This build support is experimental. Specifically, * It does not support all features of Apache httpd. * Some components may not be built correctly and/or in a manner compatible with the previous Windows build support. * Build interfaces, such as the mechanisms which are used to enable optional functionality or specify prerequisites, may change from release to release as feedback is received from users and bugs and limitations are resolved. Important: Refer to the "Known Bugs and Limitations" section for further information. It is beyond the scope of this document to document or explain how to utilize the various cmake features, such as different build backends or provisions for finding support libraries. Please refer to the cmake documentation for additional information that applies to building any project with cmake. Prerequisites ------------- The following tools must be in PATH: * cmake, version 2.8 or later cmake version 3.1.3 or later is required to work with current OpenSSL releases. (OpenSSL is an optional prerequisite of httpd.) * Perl * If the WITH_MODULES feature is used: awk * If using a command-line compiler: compiler and linker and related tools (Refer to the cmake documentation for more information.) The following support libraries are mandatory: * APR, built with cmake + Either APR 2.0-dev (trunk) or APR 1.5.x and APR-Util 1.5.x. + When building APR (but not APR-Util), specify the build option APR_INSTALL_PRIVATE_H so that non-standard files required for building Apache httpd are installed. + Additional APR settings affect httpd but are not mandatory, such as APR_HAVE_IPV6. * PCRE Certain optional features of APR 2.0-dev (trunk) or APR-Util 1.5.x allow some optional features of httpd to be enabled. For example, APU_HAVE_CRYPTO is required for mod_session_crypto. Additional support libraries allow some optional features of httpd to be enabled: * libxml2 (e.g., mod_proxy_html) * lua 5.1 (mod_lua) * nghttp2 (mod_http2) * openssl (mod_ssl and https support for ab) * zlib (mod_deflate) OpenSSL ------- If you have a binary install of OpenSSL in a well-known directory (e.g., %HOME%\OpenSSL-Win64) and you wish to build httpd against a different install of OpenSSL, the cmake build may unexpectedly select OpenSSL libraries in the well-known directory even if the expected include files are used. Check the cmake output from your httpd build to confirm that the expected OpenSSL libraries and include files are used. The cmake FindOpenSSL module searches for OpenSSL libraries in a "VC" subdirectory of the OpenSSL install with filenames that indicate the build type (e.g., "/lib/VC/ssleay32MD.lib"); defining CMAKE_PREFIX_PATH or OPENSSL_ROOT_DIR or even OPENSSL_LIBRARIES does not circumvent finding these libraries. To work around this issue, rename the well-known OpenSSL directory while building httpd. Let us know if you find a better solution. nghttp2 ------- This is required for mod_http2. cmake-based build support for nghttp2 for Windows can be found at https://github.com/trawick/nghttp2-minimal-cmake. That easily fits into a build system that already uses cmake for httpd, apr, and perhaps other packages. A dynamic build of nghttp2 using its normal Windows build system should also be usable by nghttp2. How to build ------------ 1. cd to a clean directory for building (i.e., don't build in your source tree) 2. Make sure cmake and Perl are in PATH. Additionally, some backends require compile tools in PATH. (Hint: "Visual Studio Command Prompt") In the unlikely event that you use -DWITH_MODULES, described below, make sure awk is in PATH. 3. cmake -G "some backend, like 'NMake Makefiles'" -DCMAKE_INSTALL_PREFIX=d:/path/to/httpdinst -DENABLE_foo=A|I|O|a|i -DENABLE_MODULES=A|I|O|a|i d:/path/to/httpdsource Alternately, you can use the cmake-gui and update settings in the GUI. PCRE_INCLUDE_DIR, PCRE_LIBRARIES, APR_INCLUDE_DIR, APR_LIBRARIES, NGHTTP2_INCLUDE_DIR, NGHTTP2_LIBRARIES: cmake doesn't bundle FindXXX for these packages, so the crucial information has to be specified in this manner if they aren't found in their default location. -DPCRE_INCLUDE_DIR=d:/path/to/pcreinst/include -DPCRE_LIBRARIES=d:/path/to/pcreinst/lib/pcre[d].lib These will have to be specified only if PCRE is installed to a different directory than httpd, or if debug *and* release builds of PCRE were installed there and you want to control which is used. (Currently the build will use pcred.lib (debug) if it is found in the default location and not overridden with -DPCRE_LIBRARIES.) -DAPR_INCLUDE_DIR=d:/path/to/aprinst/include -DAPR_LIBRARIES="d:/path/to/aprinst/lib/libapr-1.lib;d:/path/to/aprinst/lib/libaprutil-1.lib" These will have to be specified if APR[-Util] was installed to a different directory than httpd. When building with APR trunk (future APR 2.x, with integrated APR-Util), specify just the path to libapr-2.lib: -DAPR_LIBRARIES=d:/path/to/aprinst/lib/libapr-2.lib APR+APR-Util 1.x vs. APR trunk will be detected automatically if they are installed to the same location as httpd. APR-Util 1.x has an optional LDAP library. If APR-Util has LDAP enabled and httpd's mod_ldap and mod_authnz_ldap are being used, include the path to the LDAP library in the APR_LIBRARIES setting. (If APR and APR-Util are found in the default location, the LDAP library will be included if it is present. -DNGHTTP2_INCLUDE_DIR=d:/path/to/nghttp2inst/include (which has nghttp2/*.h) -DNGHTTP2_LIBRARIES=d:/path/to/nghttp2inst/lib/nghttp2.lib" These will have to be specified if nghttp2 was installed to a different directory than httpd. LIBXML2_ICONV_INCLUDE_DIR, LIBXML2_ICONV_LIBRARIES If using a module that requires libxml2 *and* the build of libxml2 requires iconv, set these variables to allow iconv includes and libraries to be used. For example: -DLIBXML2_ICONV_INCLUDE_DIR=c:\iconv-1.9.2.win32\include -DLIBXML2_ICONV_LIBRARIES=c:\iconv-1.9.2.win32\lib\iconv.lib CMAKE_C_FLAGS_RELEASE, _DEBUG, _RELWITHDEBINFO, _MINSIZEREL CMAKE_BUILD_TYPE For NMake Makefiles the choices are at least DEBUG, RELEASE, RELWITHDEBINFO, and MINSIZEREL Other backends may have other selections. ENABLE_foo: Each module has a default setting which can be overridden with one of the following values: A build and Activate module a build and Activate module IFF prereqs are available; if prereqs are unavailable, don't build it I build module but leave it Inactive (commented-out LoadModule directive) i build module but leave it Inactive IFF prereqs are available; if prereqs are unavailable, don't build it O Omit module completely Examples: -DENABLE_ACCESS_COMPAT=O -DENABLE_PROXY_HTML=i ENABLE_MODULES: This changes the *minimum* enablement of all modules to the specified value (one of A, a, I, i, O, as described under ENABLE_foo above). The ranking of enablement from lowest to highest is O, i, I, a, A. If a specific module has a higher rank enablement setting, either from a built-in default or from -DENABLE_foo, ENABLE_MODULES won't affect that module. However, if a specific module has a lower-rank enablement setting, presumably from a built-in default, the value of ENABLE_MODULES will be used for that module. Explanations for possible values: -DENABLE_MODULES=a build and activate all possible modules, ignoring any with missing prereqs (doesn't affect modules with A for ENABLE_foo) -DENABLE_MODULES=i build but leave inactive all possible modules, ignoring any with missing prereqs (doesn't affect modules with A, a, or I for ENABLE_foo) -DENABLE_MODULES=O no impact, since all modules are either already disabled or have a higher setting -DENABLE_MODULES=A build and activate all possible modules, failing the build if any module is missing a prereq -DENABLE_MODULES=I similar to -DENABLE_MODULES=A (doesn't affect modules with A or a for ENABLE_foo) WITH_MODULES: Comma-separated paths to single file modules to statically linked into the server, like the --with-module=modpath:/path/to/mod_foo.c with the autoconf-based build. Key differences: The modpath (e.g., "generators") isn't provided or used, and the copy of the module source being built is automatically updated when it changes. See also EXTRA_COMPILE_FLAGS, EXTRA_INCLUDES, and EXTRA_LIBS. EXTRA_COMPILE_FLAGS: Space-delimited compile flags to define with the build. EXTRA_INCLUDES: List of additional directories to search for .h files. This may be necessary when including third-party modules in the httpd build via WITH_MODULES. EXTRA_LIBS: List of additional libraries to link with. This may be necessary when including third-party modules in the httpd build via WITH_MODULES. Port and SSLPort: Port numbers for substitution into default .conf files. (The defaults are 80 and 443.) INSTALL_PDB: If .pdb files are generated for debugging, install them. Default: ON The .pdb files are generally needed for debugging low-level code problems. If they aren't installed, they are still available in the build directory for use by alternate packaging implementations or when debugging on the build machine. INSTALL_MANUAL: Install the Apache HTTP Server manual. Default: ON This could be turned off when developing changes in order to speed up installation time. 4. Build using the chosen generator (e.g., "nmake install" for cmake's "NMake Makefiles" generator). Running the server and support programs --------------------------------------- This build system does not copy binaries such as dlls from other projects into the httpd install location. Without taking some precautions, httpd and support programs can fail to start or modules can fail to load because a support library can't be found in PATH or in the directory of the httpd binary. This can be resolved in several different ways: * Install httpd and the various support libraries to a common install prefix so that support libraries and httpd programs are installed in the same bin directory and are found without setting PATH. * Update PATH to include the bin directories of all necessary support libraries. Depending on where PATH is set, it may not affect starting httpd as a service. * Maintain a script which combines required binaries into a common location, such as the httpd installion bin directory, and use that script after building or otherwise installing or updating support libraries. * AVOID THE USE of any unrepeatable process of copying dll files around from different install locations until something starts working. The result is that when you later update a support library to pick up a security fix, httpd will likely continue to use the old, vulnerable library file. Known Bugs and Limitations -------------------------- * no standard script or makefile is provided to tie together the builds of httpd and support libraries in a manner suitable for typical users * no logic to find support libraries or otherwise build these modules: + mod_socache_dc (requires distcache), mod_serf (requires serf) + additionally, mod_firehose doesn't compile on Windows anyway * buildmark.c isn't necessarily rebuilt when httpd.exe is regenerated * ApacheMonitor has a build error and is disabled * CGI examples aren't installed * dbmmanage.pl and wintty aren't built/installed * module enablement defaults are not in sync with the autoconf-based build * no support for static support library builds; unclear if that is a requirement; if so: taking PCRE as an example, we'd need to detect that it is static and then turn on PCRE_STATIC for the libhttpd build Generally: * Many httpd features have not been tested with this build. * Developers need to examine the existing Windows build in great detail and see what is missing from the cmake-based build, whether a feature or some build nuance. * Any feedback you can provide on your experiences with this build will be helpful. httpd-2.4.52/INSTALL000644 000770 000024 00000007306 12716655767 013733 0ustar00seistaff000000 000000 APACHE INSTALLATION OVERVIEW Quick Start - Unix ------------------ For complete installation documentation, see [ht]docs/manual/install.html or http://httpd.apache.org/docs/2.4/install.html $ ./configure --prefix=PREFIX $ make $ make install $ PREFIX/bin/apachectl start NOTES: * Replace PREFIX with the filesystem path under which Apache should be installed. A typical installation might use "/usr/local/apache2" for PREFIX (without the quotes). * Consider if you want to use a previously installed APR and APR-Util (such as those provided with many OSes) or if you need to use the APR and APR-Util from the apr.apache.org project. If the latter, download the latest versions and unpack them to ./srclib/apr and ./srclib/apr-util (no version numbers in the directory names) and use ./configure's --with-included-apr option. This is required if you don't have the compiler which the system APR was built with. It can also be advantageous if you are a developer who will be linking your code with Apache or using a debugger to step through server code, as it removes the possibility of version or compile-option mismatches with APR and APR-Util code. As a convenience, prepackaged source-code bundles of APR and APR-Util are occasionally also provided as a httpd-2.X.X-deps.tar.gz download. * If you are a developer building Apache directly from Subversion, you will need to run ./buildconf before running configure. This script bootstraps the build environment and requires Python as well as GNU autoconf and libtool. If you build Apache from a release tarball, you don't have to run buildconf. * If you want to build a threaded MPM (for instance worker) on FreeBSD, be aware that threads do not work well with Apache on FreeBSD versions before 5.4-RELEASE. If you wish to try a threaded Apache on an earlier version of FreeBSD, use the --enable-threads parameter to ./configure in addition to the --with-mpm parameter. * If you are building directly from Subversion on Mac OS X (Darwin), make sure to use GNU Libtool 1.4.2 or newer. All recent versions of the developer tools on this platform include a sufficiently recent version of GNU Libtool (named glibtool, but buildconf knows where to find it). For a short impression of what possibilities you have, here is a typical example which configures Apache for the installation tree /sw/pkg/apache with a particular compiler and flags plus the two additional modules mod_rewrite and mod_speling for later loading through the DSO mechanism: $ CC="pgcc" CFLAGS="-O2" \ ./configure --prefix=/sw/pkg/apache \ --enable-rewrite=shared \ --enable-speling=shared The easiest way to find all of the configuration flags for Apache 2.4 is to run ./configure --help.

OK, we all agree pretty code is good. Probably best to clean this up by hand immediately upon branching a 2.1 tree. Status: Justin volunteers to hand-edit the entire source tree ;) Justin says: Recall when the release plan for 2.0 was written: Absolute Enforcement of an "Apache Style" for code. Watch this slip into 3.0. David says: The style guide needs to be reviewed before this can be done. http://httpd.apache.org/dev/styleguide.html The current file is dated April 20th 1998! OtherBill offers: It's survived since '98 because it's welldone :-) Suggest we simply follow whatever is documented in styleguide.html as we branch the next tree. Really sort of straightforward, if you dislike a bit within that doc, bring it up on the dev@httpd list prior to the next branch. So Bill sums up ... let's get the code cleaned up in CVS head. Remember, it just takes cvs diff -b (that is, --ignore-space-change) to see the code changes and ignore that cruft. Get editing Justin :) * Replace stat [deferred open] with open/fstat in directory_walk. Justin, Ian, OtherBill all interested in this. Implies setting up the apr_file_t member in request_rec, and having all modules use that file, and allow the cleanup to close it [if it isn't a shared, cached file handle.] * The Async Apache Server implemented in terms of APR. [Bill Stoddard's pet project.] Message-ID: <008301c17d42$9b446970$01000100@sashimi> (dev@apr) OtherBill notes that this can proceed in two parts... Async accept, setup, and tear-down of the request e.g. dealing with the incoming request headers, prior to dispatching the request to a thread for processing. This doesn't need to wait for a 2.x/3.0 bump. Async delegation of the entire request processing chain Too many handlers use stack storage and presume it is available for the life of the request, so a complete async implementation would need to happen 3.0 release. Brian notes that async writes will provide a bigger scalability win than async reads for most servers. We may want to try a hybrid sync-read/async-write MPM as a next step. This should be relatively easy to build: start with the current worker or leader/followers model, but hand off each response brigade to a "completion thread" that multiplexes writes on many connections, so that the worker thread doesn't have to wait around for the sendfile to complete. MAKING APACHE REPOSITORY-AGNOSTIC (or: remove knowledge of the filesystem) [ 2002/10/01: discussion in progress on items below; this isn't planned yet ] * dav_resource concept for an HTTP resource ("ap_resource") * r->filename, r->canonical_filename, r->finfo need to disappear. All users need to use new APIs on the ap_resource object. (backwards compat: today, when this occurs with mod_dav and a custom backend, the above items refer to the topmost directory mapped by a location; e.g. docroot) Need to preserve a 'filename'-like string for mime-by-name sorts of operations. But this only needs to be the name itself and not a full path. Justin: Can we leverage the path info, or do we not trust the user? gstein: well, it isn't the "path info", but the actual URI of the resource. And of course we trust the user... that is the resource they requested. dav_resource->uri is the field you want. path_info might still exist, but that portion might be related to the CGI concept of "path translated" or some other further resolution. To continue, I would suggest that "path translated" and having *any* path info is Badness. It means that you did not fully resolve a resource for the given URI. The "abs_path" in a URI identifies a resource, and that should get fully resolved. None of this "resolve to and then we have a magical second resolution (inside the CGI script)" or somesuch. Justin: Well, let's consider mod_mbox for a second. It is sort of a virtual filesystem in its own right - as it introduces it's own notion of a URI space, but it is intrinsically tied to the filesystem to do the lookups. But, for the portion that isn't resolved on the file system, it has its own addressing scheme. Do we need the ability to layer resolution? * The translate_name hook goes away Wrowe altogether disagrees. translate_name today even operates on URIs ... this mechanism needs to be preserved. * The doc for map_to_storage is totally opaque to me. It has something to do with filesystems, but it also talks about security and per_dir_config and other stuff. I presume something needs to happen there -- at least better doc. Wrowe agrees and will write it up. * The directory_walk concept disappears. All configuration is tagged to Locations. The "mod_filesystem" module might have some internal concept of the same config appearing in multiple places, but that is handled internally rather than by Apache core. Wrowe suggests this is wrong, instead it's private to filesystem requests, and is already invoked from map_to_storage, not the core handler. and blocks are preserved as-is, but sections become specific to the filesystem handler alone. Because alternate filesystem schemes could be loaded, this should be exposed, from the core, for other file-based stores to share. Consider an archive store where the layers become -> -> Justin: How do we map Directory entries to Locations? * The "Location tree" is an in-memory representation of the URL namespace. Nodes of the tree have configuration specific to that location in the namespace. Something like: typedef struct { const char *name; /* name of this node relative to parent */ struct ap_conf_vector_t *locn_config; apr_hash_t *children; /* NULL if no child configs */ } ap_locn_node; The following config: SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 Creates a node with name=="server_status", and the node is a child of the "/" node. (hmm. node->name is redundant with the hash key; maybe drop node->name) In the config vector, mod_access has stored its Order, Deny, and Allow configs. mod_core has stored the SetHandler. During the Location walk, we merge the config vectors normally. Note that an Alias simply associates a filesystem path (in mod_filesystem) with that Location in the tree. Merging continues with child locations, but a merge is never done through filesystem locations. Config on a specific subdir needs to be mapped back into the corresponding point in the Location tree for proper merging. * Config is parsed into a tree, as we did for the 2.0 timeframe, but that tree is just a representation of the config (for multiple runs and for in-memory manipulation and usage). It is unrelated to the "Location tree". * Calls to apr_file_io functions generally need to be replaced with operations against the ap_resource. For example, rather than calling apr_dir_open/read/close(), a caller uses resource->repos->get_children() or somesuch. Note that things like mod_dir, mod_autoindex, and mod_negotiation need to be converted to use these mechanisms so that their functions will work on logical repositories rather than just filesystems. * How do we handle CGI scripts? Especially when the resource may not be backed by a file? Ideally, we should be able to come up with some mechanism to allow CGIs to work in a repository-independent manner. - Writing the virtual data as a file and then executing it? - Can a shell be executed in a streamy manner? (Portably?) - Have an 'execute_resource' hook/func that allows the repository to choose its manner - be it exec() or whatever. - Won't this approach lead to duplication of code? Helper fns? gstein: PHP, Perl, and Python scripts are nominally executed by a filter inserted by mod_php/perl/python. I'd suggest that shell/batch scripts are similar. But to ask further: what if it is an executable *program* rather than just a script? Do we yank that out of the repository, drop it onto the filesystem, and run it? eeewwwww... I'll vote -0.9 for CGIs as a filter. Keep 'em handlers. Justin: So, do we give up executing CGIs from virtual repositories? That seems like a sad tradeoff to make. I'd like to have my CGI scripts under DAV (SVN) control. * How do we handle overlaying of Location and Directory entries? Right now, we have a problem when /cgi-bin/ is ScriptAlias'd and mod_dav has control over /. Some people believe that /cgi-bin/ shouldn't be under DAV control, while others do believe it should be. What's the right strategy? httpd-2.4.52/CHANGES000644 000770 000024 00001165363 14156134734 013670 0ustar00seistaff000000 000000 -*- coding: utf-8 -*- Changes with Apache 2.4.52 *) http: Enforce that fully qualified uri-paths not to be forward-proxied have an http(s) scheme, and that the ones to be forward proxied have a hostname, per HTTP specifications.

PR 61820 [Ruediger Pluem, Roy T. Fielding] *) core: Adding SSL related inquiry functions to the server API. These function are always available, even when no module providing SSL is loaded. They provide their own "shadowing" implementation for the optional functions of similar name that mod_ssl and impersonators of mod_ssl provide. This enables loading of several SSL providing modules when all but one of them registers itself into the new hooks. Two old-style SSL modules will not work, as they replace the others optional functions with their own. Modules using the old-style optional functions will continue to work as core supplies its own versions of those. The following has been added so far: - ap_ssl_conn_is_ssl() to query if a connection is using SSL. - ap_ssl_var_lookup() to query SSL related variables for a server/connection/request. - Hooks for 'ssl_conn_is_ssl' and 'ssl_var_lookup' where modules providing SSL can install their own value supplying functions. - ap_ssl_add_cert_files() to enable other modules like mod_md to provide certificate and keys for an SSL module like mod_ssl. - ap_ssl_add_fallback_cert_files() to enable other modules like mod_md to provide a fallback certificate in case no 'proper' certificate is available for an SSL module like mod_ssl. - ap_ssl_answer_challenge() to enable other modules like mod_md to provide a certificate as used in the RFC 8555 'tls-alpn-01' challenge for the ACME protocol for an SSL module like mod_ssl. The function and its hook provide PEM encoded data instead of file names. - Hooks for 'ssl_add_cert_files', 'ssl_add_fallback_cert_files' and 'ssl_answer_challenge' where modules like mod_md can provide providers to the above mentioned functions. - These functions reside in the new 'http_ssl.h' header file. [Stefan Eissing] *) core/mod_ssl/mod_md: adding OCSP response provisioning as core feature. This allows modules to access and provide OCSP response data without being tied of each other. The data is exchanged in standard, portable formats (PEM encoded certificates and DER encoded responses), so that the actual SSL/crypto implementations used by the modules are independant of each other. Registration and retrieval happen in the context of a server (server_rec) which modules may use to decide if they are configured for this or not. The area of changes: 1. core: defines 2 functions in include/http_ssl.h, so that modules may register a certificate, together with its issuer certificate for OCSP response provisioning and ask for current response data (DER bytes) later. Also, 2 hooks are defined that allow modules to implement this OCSP provisioning. 2. mod_ssl uses the new functions, in addition to what it did already, to register its certificates this way. If no one is interested in providing OCSP, it falls back to its own (if configured) stapling implementation. 3. mod_md registers itself at the core hooks for OCSP provisioning. Depending on configuration, it will accept registrations of its own certificates only, all certificates or none. [Stefan Eissing] *) mod_md: v2.4.0 with improvements and bugfixes - MDPrivateKeys allows the specification of several types. Beside "RSA" plus optional key lengths elliptic curves can be configured. This means you can have multiple certificates for a Managed Domain with different key types. With ```MDPrivateKeys secp384r1 rsa2048``` you get one ECDSA and one RSA certificate and all modern client will use the shorter ECDSA, while older client will get the RSA certificate. Many thanks to @tlhackque who pushed and helped on this. - Support added for MDomains consisting of a wildcard. Configuring ```MDomain *.host.net``` will match all virtual hosts matching that pattern and obtain one certificate for it (assuming you have 'dns-01' challenge support configured). Addresses #239. - Removed support for ACMEv1 servers. The only known installation used to be Let's Encrypt which has disabled that version more than a year ago for new accounts. - Andreas Ulm () implemented the ```renewing``` call to ```MDMessageCmd``` that can deny a certificate renewal attempt. This is useful in clustered installations, as discussed in #233). - New event ```challenge-setup::```, triggered when the challenge data for a domain has been created. This is invoked before the ACME server is told to check for it. The type is one of the ACME challenge types. This is invoked for every DNS name in a MDomain. - The max delay for retries has been raised to daily (this is like all retries jittered somewhat to avoid repeats at fixed time of day). - Certain error codes reported by the ACME server that indicate a problem with the configured data now immediately switch to daily retries. For example: if the ACME server rejects a contact email or a domain name, frequent retries will most likely not solve the problem. But daily retries still make sense as there might be an error at the server and un-supervised certificate renewal is the goal. Refs #222. - Test case and work around for domain names > 64 octets. Fixes #227. When the first DNS name of an MD is longer than 63 octets, the certificate request will not contain a CN field, but leave it up to the CA to choose one. Currently, Lets Encrypt looks for a shorter name in the SAN list given and fails the request if none is found. But it is really up to the CA (and what browsers/libs accept here) and may change over the years. That is why the decision is best made at the CA. - Retry delays now have a random +/-[0-50]% modification applied to let retries from several servers spread out more, should they have been restarted at the same time of day. - Fixed several places where the 'badNonce' return code from an ACME server was not handled correctly. The test server 'pebble' simulates this behaviour by default and helps nicely in verifying this behaviour. Thanks, pebble! - Set the default `MDActivationDelay` to 0. This was confusing to users that new certificates were deemed not usably before a day of delay. When clocks are correct, using a new certificate right away should not pose a problem. - When handling ACME authorization resources, the module no longer requires the server to return a "Location" header, as was necessary in ACMEv1. Fixes #216. - Fixed a theoretical uninitialized read when testing for JSON error responses from the ACME CA. Reported at . - ACME problem reports from CAs that include parameters in the Content-Type header are handled correctly. (Previously, the problem text would not be reported and retries could exceed CA limits.) - Account Update transactions to V2 CAs now use the correct POST-AS-GET method. Previously, an empty JSON object was sent - which apparently LE accepted, but others reject.

[Chris Darroch] *) Fix issue which could cause error messages to be written to access logs on Win32. PR 40476. [Tom Donovan ] *) The LockFile directive, which specifies the location of the accept() mutex lockfile, is deprecated. Instead, the AcceptMutex directive now takes an optional lockfile location parameter, ala SSLMutex. [Jim Jagielski] *) mod_authn_dbd: Export any additional columns queried in the SQL select into the environment with the name AUTHENTICATE_. This brings mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett] *) mod_dbd: Key the storage of prepared statements on the hex string value of server_rec, rather than the server name, as the server name may change (eg when the server name is set) at any time, causing weird behaviour in modules dependent on mod_dbd. [Graham Leggett] *) mod_proxy_fcgi: Added win32 build. [Mladen Turk] *) sendfile_nonblocking() takes the _brigade_ as an argument, gets the first bucket from the brigade, finds it not to be a FILE bucket and barfs. The fix is to pass a bucket rather than a brigade. [Niklas Edmundsson ] *) mod_rewrite: support rewritemap by SQL query [Nick Kew] *) ap_get_server_version() has been removed. Third-party modules must now use ap_get_server_banner() or ap_get_server_description(). [Jeff Trawick] *) All MPMs: Introduce a check_config phase between pre_config and open_logs, to allow modules to review interdependent configuration directive values and adjust them while messages can still be logged to the console. Handle relevant MPM directives during this phase and format messages for both the console and the error log, as appropriate.

Move the directives 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias into mod_authn_core. [Brad Nicholes] *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy' into the new module mod_access_compat which can be loaded to provide support for these directives. [Brad Nicholes] *) Authz: Move the 'Require' directive from the core module as well as add the directives '', '', '' and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR' logic into the authorization processing. [Brad Nicholes] *) Authz: Add the new module mod_authz_core which acts as the authorization provider vector and contains common authz directives. [Brad Nicholes] *) Authz: Renamed mod_authz_dbm authz providers from 'group' and 'file-group' to 'dbm-group' and 'dbm-file-group'.

The logging of a request and the freeing of its pool are now done when the EOR bucket is destroyed. This has the effect of delaying the logging until right after the last of the response is sent; ap_core_output_filter() calls the access logger indirectly when it destroys the EOR bucket.

Originally designed as a replacement for the NCSA HTTP Server, it has grown to be the most popular web server on the Internet. As a project of the Apache Software Foundation, the developers aim to collaboratively develop and maintain a robust, commercial-grade, standards-based server with freely available source code. The Latest Version ------------------ Details of the latest version can be found on the Apache HTTP server project page under http://httpd.apache.org/. Documentation ------------- The documentation available as of the date of this release is included in HTML format in the docs/manual/ directory. The most up-to-date documentation can be found at http://httpd.apache.org/docs/2.4/. Installation ------------ Please see the file called INSTALL. Platform specific notes can be found in README.platforms. Licensing --------- Please see the file called LICENSE. Cryptographic Software Notice ----------------------------- This distribution may include software that has been designed for use with cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See for more information. The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code. The following provides more details on the included files that may be subject to export controls on cryptographic software: Apache httpd 2.0 and later versions include the mod_ssl module under modules/ssl/ for configuring and listening to connections over SSL encrypted network sockets by performing calls to a general-purpose encryption library, such as OpenSSL or the operating system's platform-specific SSL facilities. In addition, some versions of apr-util provide an abstract interface for symmetrical cryptographic functions that make use of a general-purpose encryption library, such as OpenSSL, NSS, or the operating system's platform-specific facilities. This interface is known as the apr_crypto interface, with implementation beneath the /crypto directory. The apr_crypto interface is used by the mod_session_crypto module available under modules/session for optional encryption of session information. Some object code distributions of Apache httpd, indicated with the word "crypto" in the package name, may include object code for the OpenSSL encryption library as distributed in open source form from . The above files are optional and may be removed if the cryptographic functionality is not desired or needs to be excluded from redistribution. Distribution packages of Apache httpd that include the word "nossl" in the package name have been created without the above files and are therefore not subject to this notice.

Darwin provides these tools as part of the Developers Tools package. Under Darwin, however, GNUlibtool is installed as 'glibtool' to avoid conflicting with the Darwin 'libtool' program. Apache 2 knows about this so that's not a problem. As of OS X 10.2 (Jaguar), the bundled versions work perfectly. Partly this is due to the fact that /bin/sh is now 'bash' and not 'zsh' as well as the fact that the bundled versions are up-to-date: autoconf 2.52 and (g)libtool 1.4.2. You will note that GNU libtool should actually be installed as glibtool, to avoid conflict with a Darwin program of the same name. There have been some reports that autoconf 2.52 prevents Apache's build system from correctly handling passing multi-value envvars to the build system (eg: CFLAGS="-g -O3" ./configure), causing errors. Use of bash does not seem to help in this situation. If this affects you, downgrading to autoconf 2.13 (which is installed on Darwin) will help. With Leopard (at least up to 10.5.2), when running configure you will likely see errors such as: rm: conftest.dSYM: is a directory This is a known issue and will be fixed in a later version of the autoconf suite. These errors can be safely ignored. For later versions of OS X, (10.8 and 10.9), be sure to have Xcode AND Xcode Command Line Tools installed. httpd will built both with gcc and clang. ========== FreeBSD: autoconf 2.52 creates scripts that are incompatible with the Posix shell implementation (/bin/sh) on FreeBSD. Be sure to use v2.13 of autoconf. Threaded MPMs are not supported on FreeBSD 4.x. Current releases of FreeBSD 5.x (5.2 or later) support threaded MPMs correctly. You must pass '--enable-threads=yes' to APR's configure in order to enable threads. Additionally, you must use libthr or libkse via libmap.conf as the default libc_r is still broken as of this writing. Please consult the man page for libmap.conf for more details about configuring libthr or libkse. ================ HP-UX: The dlopen() system call in HP-UX has problems when loading/unloading C++ modules. The problem can be resolved by using shl_load() instead of dlopen(). This is fixed in the Apache 2.0.44 release. To enable loading of C++ modules, the httpd binary has to be linked with the following libraries : HP-UX (11.0 / 11i): When using shl_load : "cpprt0_stub.s -lcl" When using dlopen : "cpprt0_stub.s -lcl -lCsup" HP-UX (11i version 1.5 and greater): When using dlopen/shl_load : "cpprt0_stub.s -lcl -lunwind" The cpprt0_stub.s can be downloaded from the web site : http://h21007.www2.hp.com/hpux-devtools/CXX/hpux-devtools.0107/0083.html Compile cpprt0_stub.s with the PIC option cc -c +z cpprt0_stub.s - OR - gcc -c -fPIC cpprt0_stub.s ================ AIX, using the vendor C compiler with optimization: There is an issue with compiling server/core.c with optimization enabled which has been seen with C for AIX 5.0.2.3 and above. (5.0.2.0, 5.0.2.1, and 5.0.2.2 have an additional problem with Apache 2.0.x, so either upgrade the compiler or don't use optimization in order to avoid it.) cc_r works fine with -O2 but xlc_r does not. In order to use xlc_r with -O2, apply the patch at http://www.apache.org/dist/httpd/patches/apply_to_2.0.49/aix_xlc_optimization.patch (That patch works with many recent levels of Apache 2+.) ================ Solaris: On Solaris, better performance may be achieved by using the Sun Studio compiler instead of gcc. As of version 11, it is now free (registration required). Download the compiler from: http://developers.sun.com/prodtech/cc/downloads/index.jsp If you use Sun Studio, the following compiler flags (CFLAGS) are recommended: -XO4 -xchip=generic ================ Ubuntu: You will need to ensure that you have either libtool 1.5.6 or 2.2.6b, or later. Expat 2.0.1 and PCRE 8.02 are also recommended to be installed. If building PCRE from source, you'll also need g++. httpd-2.4.52/InstallBin.dsp000644 000770 000024 00000005535 11660326534 015433 0ustar00seistaff000000 000000 # Microsoft Developer Studio Project File - Name="InstallBin" - Package Owner=<4> # Microsoft Developer Studio Generated Build File, Format Version 6.00 # ** DO NOT EDIT ** # TARGTYPE "Win32 (x86) External Target" 0x0106 CFG=InstallBin - Win32 Debug !MESSAGE This is not a valid makefile.

directly editing the CHANGES file like it was done until now or by storing each entry for the CHANGES file correctly formated in a separate file in the changes-entries directory. The benefit of the single file per change approach is that it eases backporting the CHANGES entry to a stable branch as it avoids the frequent merge conflicts as changes are merged in different orders or not at all in the stable branch. In order to keep the current CHANGES file for the users as is there is a new make target called 'update-changes'. It merges all change files in the changes-entries directory to the top of the CHANGES file and removes them afterwards. This make target can be seen in a similar way as the scripts to update the documentation files from its xml sources. It can be executed immediately after the new file in the changes-entries directory has been created / merged and committed or it can executed later. It should be executed at least before a release gets tagged. httpd-2.4.52/config.layout000644 000770 000024 00000033544 13623623272 015371 0ustar00seistaff000000 000000 ## ## config.layout -- Pre-defined Installation Path Layouts ## ## Hints: ## - layouts can be loaded with configure's --enable-layout=ID option ## - when no --enable-layout option is given, the default layout is `Apache' ## - a trailing plus character (`+') on paths is replaced with a ## `/' suffix where is currently hardcoded to 'apache2'. ## (This may become a configurable parameter at some point.) ## #

The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicate, plan, and develop the server and its related documentation. In addition, hundreds of users have contributed ideas, code, and documentation to the project. This file is intended to briefly describe the history of the Apache Group (as it was called in the early days), recognize the many contributors, and explain how you can join the fun too. In February of 1995, the most popular server software on the Web was the public domain HTTP daemon developed by Rob McCool at the National Center for Supercomputing Applications, University of Illinois, Urbana-Champaign. However, development of that httpd had stalled after Rob left NCSA in mid-1994, and many webmasters had developed their own extensions and bug fixes that were in need of a common distribution. A small group of these webmasters, contacted via private e-mail, gathered together for the purpose of coordinating their changes (in the form of "patches"). Brian Behlendorf and Cliff Skolnick put together a mailing list, shared information space, and logins for the core developers on a machine in the California Bay Area, with bandwidth and diskspace donated by HotWired and Organic Online. By the end of February, eight core contributors formed the foundation of the original Apache Group: Brian Behlendorf Roy T. Fielding Rob Hartill David Robinson Cliff Skolnick Randy Terbush Robert S. Thau Andrew Wilson with additional contributions from Eric Hagberg Frank Peters Nicolas Pioch Using NCSA httpd 1.3 as a base, we added all of the published bug fixes and worthwhile enhancements we could find, tested the result on our own servers, and made the first official public release (0.6.2) of the Apache server in April 1995. By coincidence, NCSA restarted their own development during the same period, and Brandon Long and Beth Frank of the NCSA Server Development Team joined the list in March as honorary members so that the two projects could share ideas and fixes. The early Apache server was a big hit, but we all knew that the codebase needed a general overhaul and redesign. During May-June 1995, while Rob Hartill and the rest of the group focused on implementing new features for 0.7.x (like pre-forked child processes) and supporting the rapidly growing Apache user community, Robert Thau designed a new server architecture (code-named Shambhala) which included a modular structure and API for better extensibility, pool-based memory allocation, and an adaptive pre-forking process model. The group switched to this new server base in July and added the features from 0.7.x, resulting in Apache 0.8.8 (and its brethren) in August. After extensive beta testing, many ports to obscure platforms, a new set of documentation (by David Robinson), and the addition of many features in the form of our standard modules, Apache 1.0 was released on December 1, 1995. Less than a year after the group was formed, the Apache server passed NCSA's httpd as the #1 server on the Internet. The survey by Netcraft (http://www.netcraft.com/survey/) shows that Apache is today more widely used than all other web servers combined. ============================================================================ The current project management committee of the Apache HTTP Server project (as of March, 2011) is: Aaron Bannert André Malo Astrid Stolper Ben Laurie Bojan Smojver Brad Nicholes Brian Havard Brian McCallister Chris Darroch Chuck Murcko Colm MacCárthaigh Dan Poirier Dirk-Willem van Gulik Doug MacEachern Eric Covener Erik Abele Graham Dumpleton Graham Leggett Greg Ames Greg Stein Gregory Trubetskoy Guenter Knauf Issac Goldstand Jeff Trawick Jim Gallacher Jim Jagielski Joe Orton Joe Schaefer Joshua Slive Justin Erenkrantz Ken Coar Lars Eilebrecht Manoj Kasichainula Marc Slemko Mark J.

Many 3rd-party modules, frequently used and recommended, are also freely-available and linked from the related projects page: , and their authors frequently contribute ideas, patches, and testing. Hundreds of people have made individual contributions to the Apache project. Patch contributors are listed in the CHANGES file. ============================================================================ How to become involved in the Apache project There are several levels of contributing. If you just want to send in an occasional suggestion/fix, then you can just use the bug reporting form at . You can also subscribe to the announcements mailing list (announce-subscribe@httpd.apache.org) which we use to broadcast information about new releases, bugfixes, and upcoming events. There's a lot of information about the development process (much of it in serious need of updating) to be found at . If you'd like to become an active contributor to the Apache project (the group of volunteers who vote on changes to the distributed server), then you need to start by subscribing to the dev@httpd.apache.org mailing list. One warning though: traffic is high, 1000 to 1500 messages/month. To subscribe to the list, send an email to dev-subscribe@httpd.apache.org. We recommend reading the list for a while before trying to jump in to development. NOTE: The developer mailing list (dev@httpd.apache.org) is not a user support forum; it is for people actively working on development of the server code and documentation, and for planning future directions. If you have user/configuration questions, send them to users list or to the USENET newsgroup "comp.infosystems.www.servers.unix".or for windows users, the newsgroup "comp.infosystems.www.servers.ms-windows". There is a core group of contributors (informally called the "core") which was formed from the project founders and is augmented from time to time when core members nominate outstanding contributors and the rest of the core members agree. The core group focus is more on "business" issues and limited-circulation things like security problems than on mainstream code development. The term "The Apache Group" technically refers to this core of project contributors. The Apache project is a meritocracy--the more work you have done, the more you are allowed to do. The group founders set the original rules, but they can be changed by vote of the active members. There is a group of people who have logins on our server (apache.org) and access to the svn repository. Everyone has access to the svn snapshots. Changes to the code are proposed on the mailing list and usually voted on by active members--three +1 (yes votes) and no -1 (no votes, or vetoes) are needed to commit a code change during a release cycle; docs are usually committed first and then changed as needed, with conflicts resolved by majority vote. Our primary method of communication is our mailing list. Approximately 40 messages a day flow over the list, and are typically very conversational in tone. We discuss new features to add, bug fixes, user problems, developments in the web server community, release dates, etc. The actual code development takes place on the developers' local machines, with proposed changes communicated using a patch (output of a unified "diff -u oldfile newfile" command), and committed to the source repository by one of the core developers using remote svn. Anyone on the mailing list can vote on a particular issue, but we only count those made by active members or people who are known to be experts on that part of the server. Vetoes must be accompanied by a convincing explanation. New members of the Apache Group are added when a frequent contributor is nominated by one member and unanimously approved by the voting members. In most cases, this "new" member has been actively contributing to the group's work for over six months, so it's usually an easy decision. The above describes our past and current (as of July 2000) guidelines, which will probably change over time as the membership of the group changes and our development/coordination tools improve. ============================================================================ The Apache Software Foundation (www.apache.org) The Apache Software Foundation exists to provide organizational, legal, and financial support for the Apache open-source software projects. Founded in June 1999 by the Apache Group, the Foundation has been incorporated as a membership-based, not-for-profit corporation in order to ensure that the Apache projects continue to exist beyond the participation of individual volunteers, to enable contributions of intellectual property and funds on a sound basis, and to provide a vehicle for limiting legal exposure while participating in open-source software projects. You are invited to participate in The Apache Software Foundation. We welcome contributions in many forms. Our membership consists of those individuals who have demonstrated a commitment to collaborative open-source software development through sustained participation and contributions within the Foundation's projects. Many people and companies have contributed towards the success of the Apache projects. ============================================================================ Why The Apache HTTP Server Is Free Apache HTTP Server exists to provide a robust and commercial-grade reference implementation of the HTTP protocol. It must remain a platform upon which individuals and institutions can build reliable systems, both for experimental purposes and for mission-critical purposes. We believe the tools of online publishing should be in the hands of everyone, and software companies should make their money providing value-added services such as specialized modules and support, amongst other things. We realize that it is often seen as an economic advantage for one company to "own" a market - in the software industry that means to control tightly a particular conduit such that all others must pay. This is typically done by "owning" the protocols through which companies conduct business, at the expense of all those other companies. To the extent that the protocols of the World Wide Web remain "unowned" by a single company, the Web will remain a level playing field for companies large and small. Thus, "ownership" of the protocol must be prevented, and the existence of a robust reference implementation of the protocol, available absolutely for free to all companies, is a tremendously good thing. Furthermore, Apache httpd is an organic entity; those who benefit from it by using it often contribute back to it by providing feature enhancements, bug fixes, and support for others in public newsgroups. The amount of effort expended by any particular individual is usually fairly light, but the resulting product is made very strong. This kind of community can only happen with freeware--when someone pays for software, they usually aren't willing to fix its bugs. One can argue, then, that Apache's strength comes from the fact that it's free, and if it were made "not free" it would suffer tremendously, even if that money were spent on a real development team. We want to see Apache httpd used very widely--by large companies, small companies, research institutions, schools, individuals, in the intranet environment, everywhere--even though this may mean that companies who could afford commercial software, and would pay for it without blinking, might get a "free ride" by using Apache httpd. We would even be happy if some commercial software companies completely dropped their own HTTP server development plans and used Apache httpd as a base, with the proper attributions as described in the LICENSE file.

must balance two competing and disjoint objectives: maintain stable code for third party authors, distributors and most importantly users so that bug and security fixes can be quickly adopted without significant hardship due to user-visible changes; and continue the development process that requires ongoing redesign to correct earlier oversights and to add additional features. The Apache HTTP Server, through version 2.0, used the Module Magic Number (MMN) to reflect API changes. This had the shortcoming of often leaving users hunting to replace binary third party modules that were now incompatible. This also left module authors searching through the API change histories to determine the exact cause for the MMN change and whether their module was affected. With the simultaneous release of Apache 2.2-stable and Apache 2.3-development, the Apache HTTP Server project is moving towards a more predictable stable release cycle, while allowing forward progress to occur without concern for breaking the stable branch. This document explains the rationale between the two versions and their behavior. STABLE RELEASES, 2.{even}.{revision} ------------------------------------ All even numbered releases will be considered stable revisions. Stable revisions will retain forward compatibility to the maximum possible extent. Features may be added during minor revisions, and features may be deprecated by making appropriate notations in the documentation, but no features may be removed. In essence, that implies that you can upgrade from one minor revision to the next with a minimum of trouble. In particular, this means: * The Module API will retain forward compatibility. It will not be necessary to update modules to work with new revisions of the stable tree. * The run-time configuration will be forward compatible. No configuration changes will be necessary to work with new revisions of the stable tree. * Compile-time configuration will be forward compatible. The configure command line options that work in one release of the stable tree will also work in the next release. As always, it will be necessary to test any new release to assure that it works correctly with a particular configuration and a particular set of modules, but every effort will be made to assure that upgrades are as smooth as possible. In addition, the following development restrictions will aid in keeping the stable tree as safe as possible: * No 'Experimental' modules; while it may be possible (based on API changes required to support a given module) to load a 2.3-development module into a 2.2-stable build of Apache, there are no guarantees. Experimental modules will be introduced to the 2.3-development versions and either added to 2.2-stable once they are proven and compatible, or deferred to the 2.4-stable release if they cannot be incorporated in the current stable release due to API change requirements. * The stable subversion tree should not remain unstable at any time. Atomic commits ought be used to introduce code from the development version to the stable tree. At any given time a security release may be in preparation, unbeknownst to other contributors. At any given time, testers may be checking out SVN trunk to confirm that a bug has been corrected. And as all code was well-tested in development prior to committing to the stable tree, there is really no reason for this tree to be broken for more than a few minutes during a lengthy commit. In order to avoid 'skipped' release numbers in the stable releases, the Release Manager will generally roll a release candidate (APACHE_#_#_#_RC#) tag. Release Candidate tarballs will be announced to the stable-testers@httpd.apache.org for the stable tree. Then, the participants will vote on the quality of the proposed release tarball. The final APACHE_#_#_# tag will not exist until the APACHE_#_#_#_RC# candidate has passed the usual votes to release that version. Only then is the final tarball packaged, removing all -rc# designations from the version number, and tagging the tree with the release number. DEVELOPMENT RELEASES, 2.{odd}.{revision} ----------------------------------------- All odd numbered releases designate the 'next' possible stable release, therefore the current development version will always be one greater than the current stable release. Work proceeds on development releases, permitting the modification of the MMN at any time in order to correct deficiencies or shortcomings in the API. This means that modules from one development release to another may not be binary compatible, or may not successfully compile without modification to accommodate the API changes. The only 'supported' development release at any time will be the most recently released version. Developers will not be answering bug reports of older development releases once a new release is available. It becomes the responsibility of the reporter to use the latest development version to confirm that any issue still exists. Any new code, new API features or new ('experimental') modules may be promoted at any time to the next stable release, by a vote of the project contributors. This vote is based on the technical stability of the new code and the stability of the interface. Once moved to stable, that feature cannot change for the remainder of that stable release cycle, so the vote must reflect that the final decisions on the behavior and naming of that new feature were reached. Vetos continue to apply to this choice of introducing the new work to the stable version. At any given time, when the quality of changes to the development branch is considered release quality, that version may become a candidate for the next stable release. This includes some or all of the API changes, promoting experimental modules to stable or deprecating and eliminating older modules from the last stable release. All of these choices are considered by the project as a group in the interests of promoting the stable release, so that any given change may be 'deferred' for a future release by the group, rather than introduce unacceptable risks to adopting the next stable release. Third party module authors are strongly encouraged to test with the latest development version. This assures that the module will be ready for the next stable release, but more importantly, the author can react to shortcomings in the API early enough to warn the dev@httpd.apache.org community of the shortcomings so that they can be addressed before the stable release. The entire burden is on the module author to anticipate the needs of their module before the stable release is created. Once a new stable release cycle has begun, that API will be present for the lifetime of the stable release. Any desired changes in the stable versions must wait for inclusion into the next release cycle. When deciding to promote a development tree to being stable, a determination should be made whether the changes since the last stable version warrant a major version bump. That is, if 2.2 is the current stable version and 2.3 is 'ready' to become stable, the group needs to decide if the next stable version is 2.4 or 3.0. One suggested rule of thumb is that if it requires too much effort to port a module from 2.2 to 2.4, then the stable version should be labeled 3.0. In order to ease the burden of creating development releases, the process for packaging a development releases is less formal than for the stable release. This strategy reflects the fact that while in development, versions are cheap. Development releases may be classified as alpha, beta, or GA to reflect the group's perceived stability of the tree. Development releases may be made at any time by any committer.

(i.e. usually for logging, files, or memory allocation in * itself or a called function.) * - struct magic has been converted from an array to a single-ended linked * list because it only grows one record at a time, it's only accessed * sequentially, and the Apache API has no equivalent of realloc(). * - Functions have been changed to get their parameters from the server * configuration instead of globals. (It should be reentrant now but has * not been tested in a threaded environment.) * - Places where it used to print results to stdout now saves them in a * list where they're used to set the MIME type in the Apache request * record. * - Command-line flags have been removed since they will never be used here. * * Ian Kluft * Engineering Information Framework * Central Engineering * Cisco Systems, Inc. * San Jose, CA, USA * * Initial installation July/August 1996 * Misc bug fixes May 1997 * Submission to Apache Software Foundation July 1997 * */ #include "apr.h" #include "apr_strings.h" #include "apr_lib.h" #define APR_WANT_STRFUNC #include "apr_want.h" #if APR_HAVE_UNISTD_H #include #endif #include "ap_config.h" #include "httpd.h" #include "http_config.h" #include "http_request.h" #include "http_core.h" #include "http_log.h" #include "http_protocol.h" #include "util_script.h" /* ### this isn't set by configure? does anybody set this? */ #ifdef HAVE_UTIME_H #include #endif /* * data structures and related constants */ #define MODNAME "mod_mime_magic" #define MIME_MAGIC_DEBUG 0 #define MIME_BINARY_UNKNOWN "application/octet-stream" #define MIME_TEXT_UNKNOWN "text/plain" #define MAXMIMESTRING 256 /* HOWMANY must be at least 4096 to make gzip -dcq work */ #define HOWMANY 4096 /* SMALL_HOWMANY limits how much work we do to figure out text files */ #define SMALL_HOWMANY 1024 #define MAXDESC 50 /* max leng of text description */ #define MAXstring 64 /* max leng of "string" types */ struct magic { struct magic *next; /* link to next entry */ int lineno; /* line number from magic file */ short flag; #define INDIR 1 /* if '>(...)' appears, */ #define UNSIGNED 2 /* comparison is unsigned */ short cont_level; /* level of ">" */ struct { char type; /* byte short long */ long offset; /* offset from indirection */ } in; long offset; /* offset to magic number */ unsigned char reln; /* relation (0=eq, '>'=gt, etc) */ char type; /* int, short, long or string. */ char vallen; /* length of string value, if any */ #define BYTE 1 #define SHORT 2 #define LONG 4 #define STRING 5 #define DATE 6 #define BESHORT 7 #define BELONG 8 #define BEDATE 9 #define LESHORT 10 #define LELONG 11 #define LEDATE 12 union VALUETYPE { unsigned char b; unsigned short h; unsigned long l; char s[MAXstring]; unsigned char hs[2]; /* 2 bytes of a fixed-endian "short" */ unsigned char hl[4]; /* 2 bytes of a fixed-endian "long" */ } value; /* either number or string */ unsigned long mask; /* mask before comparison with value */ char nospflag; /* suppress space character */ /* NOTE: this string is suspected of overrunning - find it! */ char desc[MAXDESC]; /* description */ }; /* * data structures for tar file recognition * -------------------------------------------------------------------------- * Header file for public domain tar (tape archive) program. * * @(#)tar.h 1.20 86/10/29 Public Domain.

Directives can appear in * configuration files or in .htaccess files so expiry semantics can * be defined on a per-directory basis. * * DIRECTIVE SYNTAX * * Valid directives are: * * ExpiresActive on | off * ExpiresDefault <code><seconds> * ExpiresByType type/encoding <code><seconds> * * Valid values for <code> are: * * 'M' expires header shows file modification date + <seconds> * 'A' expires header shows access time + <seconds> * * [I'm not sure which of these is best under different * circumstances, I guess it's for other people to explore. * The effects may be indistinguishable for a number of cases] * * <seconds> should be an integer value [acceptable to atoi()] * * There is NO space between the <code> and <seconds>. * * For example, a directory which contains information which changes * frequently might contain: * * # reports generated by cron every hour. don't let caches * # hold onto stale information * ExpiresDefault M3600 * * Another example, our html pages can change all the time, the gifs * tend not to change often: * * # pages are hot (1 week), images are cold (1 month) * ExpiresByType text/html A604800 * ExpiresByType image/gif A2592000 * * Expires can be turned on for all URLs on the server by placing the * following directive in a conf file: * * ExpiresActive on * * ExpiresActive can also appear in .htaccess files, enabling the * behaviour to be turned on or off for each chosen directory. * * # turn off Expires behaviour in this directory * # and subdirectories * ExpiresActive off * * Directives defined for a directory are valid in subdirectories * unless explicitly overridden by new directives in the subdirectory * .htaccess files. * * ALTERNATIVE DIRECTIVE SYNTAX * * Directives can also be defined in a more readable syntax of the form: * * ExpiresDefault "<base> [plus] {<num> <type>}*" * ExpiresByType type/encoding "<base> [plus] {<num> <type>}*" * * where <base> is one of: * access * now equivalent to 'access' * modification * * where the 'plus' keyword is optional * * where <num> should be an integer value [acceptable to atoi()] * * where <type> is one of: * years * months * weeks * days * hours * minutes * seconds * * For example, any of the following directives can be used to make * documents expire 1 month after being accessed, by default: * * ExpiresDefault "access plus 1 month" * ExpiresDefault "access plus 4 weeks" * ExpiresDefault "access plus 30 days" * * The expiry time can be fine-tuned by adding several '<num> <type>' * clauses: * * ExpiresByType text/html "access plus 1 month 15 days 2 hours" * ExpiresByType image/gif "modification plus 5 hours 3 minutes" * * --- * * Change-log: * 29.Jan.96 Hardened the add_* functions. Server will now bail out * if bad directives are given in the conf files. * 02.Feb.96 Returns DECLINED if not 'ExpiresActive on', giving other * expires-aware modules a chance to play with the same * directives. [Michael Rutman] * 03.Feb.96 Call tzset() before localtime(). Trying to get the module * to work properly in non GMT timezones. * 12.Feb.96 Modified directive syntax to allow more readable commands: * ExpiresDefault "now plus 10 days 20 seconds" * ExpiresDefault "access plus 30 days" * ExpiresDefault "modification plus 1 year 10 months 30 days" * 13.Feb.96 Fix call to table_get() with NULL 2nd parameter [Rob Hartill] * 19.Feb.96 Call gm_timestr_822() to get time formatted correctly, can't * rely on presence of HTTP_TIME_FORMAT in Apache 1.1+. * 21.Feb.96 This version (0.0.9) reverses assumptions made in 0.0.8 * about star/star handlers. Reverting to 0.0.7 behaviour. * 08.Jun.96 allows ExpiresDefault to be used with responses that use * the DefaultType by not DECLINING, but instead skipping * the table_get check and then looking for an ExpiresDefault. * [Rob Hartill] * 04.Nov.96 'const' definitions added. * * TODO * add support for Cache-Control: max-age=20 from the HTTP/1.1 * proposal (in this case, a ttl of 20 seconds) [ask roy] * add per-file expiry and explicit expiry times - duplicates some * of the mod_cern_meta.c functionality. eg: * ExpiresExplicit index.html "modification plus 30 days" * * BUGS * Hi, welcome to the internet. */ #include "apr.h" #include "apr_strings.h" #include "apr_lib.h" #define APR_WANT_STRFUNC #include "apr_want.h" #include "ap_config.h" #include "httpd.h" #include "http_config.h" #include "http_log.h" #include "http_request.h" #include "http_protocol.h" typedef struct { int active; int wildcards; char *expiresdefault; apr_table_t *expiresbytype; } expires_dir_config; /* from mod_dir, why is this alias used? */ #define DIR_CMD_PERMS OR_INDEXES #define ACTIVE_ON 1 #define ACTIVE_OFF 0 #define ACTIVE_DONTCARE 2 module AP_MODULE_DECLARE_DATA expires_module; static void *create_dir_expires_config(apr_pool_t *p, char *dummy) { expires_dir_config *new = (expires_dir_config *) apr_pcalloc(p, sizeof(expires_dir_config)); new->active = ACTIVE_DONTCARE; new->wildcards = 0; new->expiresdefault = NULL; new->expiresbytype = apr_table_make(p, 4); return (void *) new; } static const char *set_expiresactive(cmd_parms *cmd, void *in_dir_config, int arg) { expires_dir_config *dir_config = in_dir_config; /* if we're here at all it's because someone explicitly * set the active flag */ dir_config->active = ACTIVE_ON; if (arg == 0) { dir_config->active = ACTIVE_OFF; } return NULL; } /* check_code() parse 'code' and return NULL or an error response * string.

Previous versions of the module defined behaviour * on a per-server basis. The upshot is that you'll need to revisit your * configuration files in order to make use of the new module. * *** * * Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP * headers that can be output in addition to the normal range of * headers for each file accessed. They appear rather like the Apache * .asis files, and are able to provide a crude way of influencing * the Expires: header, as well as providing other curiosities. * There are many ways to manage meta information, this one was * chosen because there is already a large number of CERN users * who can exploit this module. It should be noted that there are probably * more sensitive ways of managing the Expires: header specifically. * * The module obeys the following directives, which can appear * in the server's .conf files and in .htaccess files. * * MetaFiles <on|off> * * turns on|off meta file processing for any directory. * Default value is off * * # turn on MetaFiles in this directory * MetaFiles on * * MetaDir <directory name> * * specifies the name of the directory in which Apache can find * meta information files. The directory is usually a 'hidden' * subdirectory of the directory that contains the file being * accessed. eg: * * # .meta files are in the *same* directory as the * # file being accessed * MetaDir . * * the default is to look in a '.web' subdirectory. This is the * same as for CERN 3.+ webservers and behaviour is the same as * for the directive: * * MetaDir .web * * MetaSuffix <meta file suffix> * * specifies the file name suffix for the file containing the * meta information. eg: * * # our meta files are suffixed with '.cern_meta' * MetaSuffix .cern_meta * * the default is to look for files with the suffix '.meta'. This * behaviour is the same as for the directive: * * MetaSuffix .meta * * When accessing the file * * DOCUMENT_ROOT/somedir/index.html * * this module will look for the file * * DOCUMENT_ROOT/somedir/.web/index.html.meta * * and will use its contents to generate additional MIME header * information. * * For more information on the CERN Meta file semantics see: * * http://www.w3.org/hypertext/WWW/Daemon/User/Config/General.html#MetaDir * * Change-log: * 29.Jan.96 pfopen/pfclose instead of fopen/fclose * DECLINE when real file not found, we may be checking each * of the index.html/index.shtml/index.htm variants and don't * need to report missing ones as spurious errors. * 31.Jan.96 log_error reports about a malformed .meta file, rather * than a script error. * 20.Jun.96 MetaFiles <on|off> default off, added, so that module * can be configured per-directory. Prior to this the module * was running for each request anywhere on the server, naughty.. * 29.Jun.96 All directives made per-directory. */ #include "apr.h" #include "apr_strings.h" #define APR_WANT_STRFUNC #include "apr_want.h" #if APR_HAVE_SYS_TYPES_H #include <sys/types.h> #endif #include "ap_config.h" #include "httpd.h" #include "http_config.h" #include "util_script.h" #include "http_log.h" #include "http_request.h" #include "http_protocol.h" #include "apr_lib.h" #define DIR_CMD_PERMS OR_INDEXES #define DEFAULT_METADIR ".web" #define DEFAULT_METASUFFIX ".meta" #define DEFAULT_METAFILES 0 module AP_MODULE_DECLARE_DATA cern_meta_module; typedef struct { const char *metadir; const char *metasuffix; int metafiles; } cern_meta_dir_config; static void *create_cern_meta_dir_config(apr_pool_t *p, char *dummy) { cern_meta_dir_config *new = (cern_meta_dir_config *) apr_palloc(p, sizeof(cern_meta_dir_config)); new->metadir = NULL; new->metasuffix = NULL; new->metafiles = DEFAULT_METAFILES; return new; } static void *merge_cern_meta_dir_configs(apr_pool_t *p, void *basev, void *addv) { cern_meta_dir_config *base = (cern_meta_dir_config *) basev; cern_meta_dir_config *add = (cern_meta_dir_config *) addv; cern_meta_dir_config *new = (cern_meta_dir_config *) apr_palloc(p, sizeof(cern_meta_dir_config)); new->metadir = add->metadir ? add->metadir : base->metadir; new->metasuffix = add->metasuffix ? add->metasuffix : base->metasuffix; new->metafiles = add->metafiles; return new; } static const char *set_metadir(cmd_parms *parms, void *in_dconf, const char *arg) { cern_meta_dir_config *dconf = in_dconf; dconf->metadir = arg; return NULL; } static const char *set_metasuffix(cmd_parms *parms, void *in_dconf, const char *arg) { cern_meta_dir_config *dconf = in_dconf; dconf->metasuffix = arg; return NULL; } static const char *set_metafiles(cmd_parms *parms, void *in_dconf, int arg) { cern_meta_dir_config *dconf = in_dconf; dconf->metafiles = arg; return NULL; } static const command_rec cern_meta_cmds[] = { AP_INIT_FLAG("MetaFiles", set_metafiles, NULL, DIR_CMD_PERMS, "Limited to 'on' or 'off'"), AP_INIT_TAKE1("MetaDir", set_metadir, NULL, DIR_CMD_PERMS, "the name of the directory containing meta files"), AP_INIT_TAKE1("MetaSuffix", set_metasuffix, NULL, DIR_CMD_PERMS, "the filename suffix for meta files"), {NULL} }; /* XXX: this is very similar to ap_scan_script_header_err_core... * are the differences deliberate, or just a result of bit rot? */ static int scan_meta_file(request_rec *r, apr_file_t *f) { char w[MAX_STRING_LEN]; char *l; int p; apr_table_t *tmp_headers; tmp_headers = apr_table_make(r->pool, 5); while (apr_file_gets(w, MAX_STRING_LEN - 1, f) == APR_SUCCESS) { /* Delete terminal (CR?)LF */ p = strlen(w); if (p > 0 && w[p - 1] == '\n') { if (p > 1 && w[p - 2] == '\015') w[p - 2] = '\0'; else w[p - 1] = '\0'; } if (w[0] == '\0') { return OK; } /* if we see a bogus header don't ignore it.

This means you should not * *** use cookies generated by this module for authentication purposes * * This Apache module is designed to track users paths through a site. * It uses the client-side state ("Cookie") protocol developed by Netscape. * It is known to work on most browsers. * * Each time a page is requested we look to see if the browser is sending * us a Cookie: header that we previously generated. * * If we don't find one then the user hasn't been to this site since * starting their browser or their browser doesn't support cookies. So * we generate a unique Cookie for the transaction and send it back to * the browser (via a "Set-Cookie" header) * Future requests from the same browser should keep the same Cookie line. * * By matching up all the requests with the same cookie you can * work out exactly what path a user took through your site. To log * the cookie use the " %{Cookie}n " directive in a custom access log; * * Example 1 : If you currently use the standard Log file format (CLF) * and use the command "TransferLog somefilename", add the line * LogFormat "%h %l %u %t \"%r\" %s %b %{Cookie}n" * to your config file. * * Example 2 : If you used to use the old "CookieLog" directive, you * can emulate it by adding the following command to your config file * CustomLog filename "%{Cookie}n \"%r\" %t" * * Mark Cox, mjc@apache.org, 6 July 95 * * This file replaces mod_cookies.c */ #include "apr.h" #include "apr_lib.h" #include "apr_strings.h" #define APR_WANT_STRFUNC #include "apr_want.h" #include "httpd.h" #include "http_config.h" #include "http_core.h" #include "http_request.h" #include "http_log.h" module AP_MODULE_DECLARE_DATA usertrack_module; typedef struct { int always; int expires; } cookie_log_state; typedef enum { CT_UNSET, CT_NETSCAPE, CT_COOKIE, CT_COOKIE2 } cookie_type_e; typedef struct { int enabled; cookie_type_e style; const char *cookie_name; const char *cookie_domain; char *regexp_string; /* used to compile regexp; save for debugging */ ap_regex_t *regexp; /* used to find usertrack cookie in cookie header */ int is_secure; int is_httponly; const char *samesite; } cookie_dir_rec; /* Make Cookie: Now we have to generate something that is going to be * pretty unique.

'name' may be a regex when it is used * to specify an HTTP request header name. The 'value' of the header & (or the value of the special value from below) are compared against * the regex argument.

Essentially "everywhere" should include all possible * httpds across all servers at a particular "site". We make some assumptions * that if the site has a cluster of machines then their time is relatively * synchronized. We also assume that the first address returned by a * gethostbyname (gethostname()) is unique across all the machines at the * "site". * * The root is assumed to absolutely uniquely identify this one child * from all other currently running children on all servers (including * this physical server if it is running multiple httpds) from each * other. * * The stamp and counter are used to distinguish all hits for a * particular root. The stamp is updated using r->request_time, * saving cpu cycles. The counter is never reset, and is used to * permit up to 64k requests in a single second by a single child. * * The 144-bits of unique_id_rec are encoded using the alphabet * [A-Za-z0-9@-], resulting in 24 bytes of printable characters. That is then * stuffed into the environment variable UNIQUE_ID so that it is available to * other modules. The alphabet choice differs from normal base64 encoding * [A-Za-z0-9+/] because + and / are special characters in URLs and we want to * make it easy to use UNIQUE_ID in URLs. * * Note that UNIQUE_ID should be considered an opaque token by other * applications. No attempt should be made to dissect its internal components. * It is an abstraction that may change in the future as the needs of this * module change. * * It is highly desirable that identifiers exist for "eternity". But future * needs (such as much faster webservers, or moving to a * multithreaded server) may dictate a need to change the contents of * unique_id_rec. Such a future implementation should ensure that the first * field is still a time_t stamp. By doing that, it is possible for a site to * have a "flag second" in which they stop all of their old-format servers, * wait one entire second, and then start all of their new-servers. This * procedure will ensure that the new space of identifiers is completely unique * from the old space. (Since the first four unencoded bytes always differ.) * * Note: previous implementations used 32-bits of IP address plus pid * in place of the PRNG output in the "root" field. This was * insufficient for IPv6-only hosts, required working DNS to determine * a unique IP address (fragile), and needed a [0, 1) second sleep * call at startup to avoid pid reuse. Use of the PRNG avoids all * these issues. */ /* * Sun Jun 7 05:43:49 CEST 1998 -- Alvaro * More comments: * 1) The UUencoding procedure is now done in a general way, avoiding the problems * with sizes and paddings that can arise depending on the architecture. Now the * offsets and sizes of the elements of the unique_id_rec structure are calculated * in unique_id_global_init; and then used to duplicate the structure without the * paddings that might exist. The multithreaded server fix should be now very easy: * just add a new "tid" field to the unique_id_rec structure, and increase by one * UNIQUE_ID_REC_MAX. * 2) unique_id_rec.stamp has been changed from "time_t" to "unsigned int", because * its size is 64bits on some platforms (linux/alpha), and this caused problems with * htonl/ntohl.

The RequestHeader directive can be used * to add/replace/remove HTTP headers before a request message is processed. * Valid in both per-server and per-dir configurations. * * Syntax is: * * Header action header value * RequestHeader action header value * * Where action is one of: * set - set this header, replacing any old value * add - add this header, possible resulting in two or more * headers with the same name * append - append this text onto any existing header of this same * merge - merge this text onto any existing header of this same, * avoiding duplicate values * unset - remove this header * edit - transform the header value according to a regexp * * Where action is unset, the third argument (value) should not be given. * The header name can include the colon, or not. * * The Header and RequestHeader directives can only be used where allowed * by the FileInfo override. * * When the request is processed, the header directives are processed in * this order: firstly, the main server, then the virtual server handling * this request (if any), then any <Directory> sections (working downwards * from the root dir), then an <Location> sections (working down from * shortest URL component), the any <File> sections. This order is * important if any 'set' or 'unset' actions are used. For example, * the following two directives have different effect if applied in * the reverse order: * * Header append Author "John P. Doe" * Header unset Author * * Examples: * * To set the "Author" header, use * Header add Author "John P. Doe" * * To remove a header: * Header unset Author * */ #include "apr.h" #include "apr_lib.h" #include "apr_strings.h" #include "apr_buckets.h" #include "apr_hash.h" #define APR_WANT_STRFUNC #include "apr_want.h" #include "httpd.h" #include "http_config.h" #include "http_request.h" #include "http_ssl.h" #include "http_log.h" #include "util_filter.h" #include "http_protocol.h" #include "ap_expr.h" /* format_tag_hash is initialized during pre-config */ static apr_hash_t *format_tag_hash; typedef enum { hdr_add = 'a', /* add header (could mean multiple hdrs) */ hdr_set = 's', /* set (replace old value) */ hdr_append = 'm', /* append (merge into any old value) */ hdr_merge = 'g', /* merge (merge, but avoid duplicates) */ hdr_unset = 'u', /* unset header */ hdr_echo = 'e', /* echo headers from request to response */ hdr_edit = 'r', /* change value by regexp, match once */ hdr_edit_r = 'R', /* change value by regexp, everymatch */ hdr_setifempty = 'i', /* set value if header not already present*/ hdr_note = 'n' /* set value of header in a note */ } hdr_actions; /* * magic cmd->info values */ static char hdr_in = '0'; /* RequestHeader */ static char hdr_out_onsuccess = '1'; /* Header onsuccess */ static char hdr_out_always = '2'; /* Header always */ /* Callback function type. */ typedef const char *format_tag_fn(request_rec *r, char *a); /* * There is an array of struct format_tag per Header/RequestHeader * config directive */ typedef struct { format_tag_fn *func; char *arg; } format_tag; /* 'Magic' condition_var value to run action in post_read_request */ static const char* condition_early = "early"; /* * There is one "header_entry" per Header/RequestHeader config directive */ typedef struct { hdr_actions action; const char *header; apr_array_header_t *ta; /* Array of format_tag structs */ ap_regex_t *regex; const char *condition_var; const char *subs; ap_expr_info_t *expr; ap_expr_info_t *expr_out; } header_entry; /* echo_do is used for Header echo to iterate through the request headers*/ typedef struct { request_rec *r; header_entry *hdr; } echo_do; /* edit_do is used for Header edit to iterate through the request headers */ typedef struct { request_rec *r; header_entry *hdr; apr_table_t *t; } edit_do; /* * headers_conf is our per-module configuration.

The database provider decides how and where to ** store these databases. ** ** The DBM keys for the properties have the following form: ** ** namespace ":" propname ** ** For example: 5:author ** ** The namespace provides an integer index into the namespace table ** (see below). propname is simply the property name, without a namespace ** prefix. ** ** A special case exists for properties that had a prefix starting with ** "xml". The XML Specification reserves these for future use. mod_dav ** stores and retrieves them unchanged. The keys for these properties ** have the form: ** ** ":" propname ** ** The propname will contain the prefix and the property name. For ** example, a key might be ":xmlfoo:name" ** ** The ":name" style will also be used for properties that do not ** exist within a namespace. ** ** The DBM values consist of two null-terminated strings, appended ** together (the null-terms are retained and stored in the database). ** The first string is the xml:lang value for the property. An empty ** string signifies that a lang value was not in context for the value. ** The second string is the property value itself. ** ** ** NAMESPACE TABLE ** ** The namespace table is an array that lists each of the namespaces ** that are in use by the properties in the given propdb. Each entry ** in the array is a simple URI. ** ** For example: http://www.foo.bar/standards/props/ ** ** The prefix used for the property is stripped and the URI for it ** is entered into the namespace table. Also, any namespaces used ** within the property value will be entered into the table (and ** stripped from the child elements). ** ** The namespaces are stored in the DBM database under the "METADATA" key. ** ** ** STRIPPING NAMESPACES ** ** Within the property values, the namespace declarations (xmlns...) ** are stripped. Each element and attribute will have its prefix removed ** and a new prefix inserted. ** ** This must be done so that we can return multiple properties in a ** PROPFIND which may have (originally) used conflicting prefixes. For ** that case, we must bind all property value elements to new namespace ** values. ** ** This implies that clients must NOT be sensitive to the namespace ** prefix used for their properties. It WILL change when the properties ** are returned (we return them as "ns", e.g. "ns5"). Also, the ** property value can contain ONLY XML elements and CDATA. PI and comment ** elements will be stripped. CDATA whitespace will be preserved, but ** whitespace within element tags will be altered. Attribute ordering ** may be altered. Element and CDATA ordering will be preserved. ** ** ** ATTRIBUTES ON PROPERTY NAME ELEMENTS ** ** When getting/setting properties, the XML used looks like: ** ** ** value ** value ** ** ** This implementation (mod_dav) DOES NOT save any attributes that are ** associated with the element. The property value is deemed ** to be only the contents ("value" in the above example). ** ** We do store the xml:lang value (if any) that applies to the context ** of the element. Whether the xml:lang attribute is on ** itself, or from a higher level element, we will store it ** with the property value. ** ** ** VERSIONING ** ** The DBM db contains a key named "METADATA" that holds database-level ** information, such as the namespace table. The record also contains the ** db's version number as the very first 16-bit value. This first number ** is actually stored as two single bytes: the first byte is a "major" ** version number. The second byte is a "minor" number. ** ** If the major number is not what mod_dav expects, then the db is closed ** immediately and an error is returned. A minor number change is ** acceptable -- it is presumed that old/new dav_props.c can deal with ** the database format. For example, a newer dav_props might update the ** minor value and append information to the end of the metadata record ** (which would be ignored by previous versions). ** ** ** ISSUES: ** ** At the moment, for the dav_get_allprops() and dav_get_props() functions, ** we must return a set of xmlns: declarations for ALL known namespaces ** in the file. There isn't a way to filter this because we don't know ** which are going to be used or not. Examining property names is not ** sufficient because the property values could use entirely different ** namespaces. ** ** ==> we must devise a scheme where we can "garbage collect" the namespace ** entries from the property database. */ #include "apr.h" #include "apr_strings.h" #define APR_WANT_STDIO #define APR_WANT_BYTEFUNC #include "apr_want.h" #include "mod_dav.h" #include "http_log.h" #include "http_request.h" /* ** There is some rough support for writable DAV:getcontenttype and ** DAV:getcontentlanguage properties.

 *
 * /server-status - Returns page using tables
 * /server-status?notable - Returns page for browsers without table support
 * /server-status?refresh - Returns page with 1 second refresh
 * /server-status?refresh=6 - Returns page with refresh every 6 seconds
 * /server-status?auto - Returns page with data for automatic parsing
 *
 * Mark Cox, mark@ukweb.com, November 1995
 *
 * 12.11.95 Initial version for www.telescope.org
 * 13.3.96  Updated to remove rprintf's [Mark]
 * 18.3.96  Added CPU usage, process information, and tidied [Ben Laurie]
 * 18.3.96  Make extra Scoreboard variables #definable
 * 25.3.96  Make short report have full precision [Ben Laurie suggested]
 * 25.3.96  Show uptime better [Mark/Ben Laurie]
 * 29.3.96  Better HTML and explanation [Mark/Rob Hartill suggested]
 * 09.4.96  Added message for non-STATUS compiled version
 * 18.4.96  Added per child and per slot counters [Jim Jagielski]
 * 01.5.96  Table format, cleanup, even more spiffy data [Chuck Murcko/Jim J.]
 * 18.5.96  Adapted to use new rprintf() routine, incidentally fixing a missing
 *          piece in short reports [Ben Laurie]
 * 21.5.96  Additional Status codes (DNS and LOGGING only enabled if
 *          extended STATUS is enabled) [George Burgyan/Jim J.]
 * 10.8.98  Allow for extended status info at runtime (no more STATUS)

/*
 * mod_userdir... implement the UserDir command.  Broken away from the
 * Alias stuff for a couple of good and not-so-good reasons:
 *
 * 1) It shows a real minimal working example of how to do something like
 *    this.
 * 2) I know people who are actually interested in changing this *particular*
 *    aspect of server functionality without changing the rest of it.  That's
 *    what this whole modular arrangement is supposed to be good at...
 *
 * Modified by Alexei Kosut to support the following constructs
 * (server running at www.foo.com, request for /~bar/one/two.html)
 *
 * UserDir public_html      -> ~bar/public_html/one/two.html
 * UserDir /usr/web         -> /usr/web/bar/one/two.html
 * UserDir /home/ * /www     -> /home/bar/www/one/two.html
 *  NOTE: theses ^ ^ space only added allow it to work in a comment, ignore
 * UserDir http://x/users   -> (302) http://x/users/bar/one/two.html
 * UserDir http://x/ * /y     -> (302) http://x/bar/y/one/two.html
 *  NOTE: here also ^ ^
 *
 * In addition, you can use multiple entries, to specify alternate
 * user directories (a la Directory Index). For example:
 *
 * UserDir public_html /usr/web http://www.xyz.com/users
 *
 * Modified by Ken Coar to provide for the following:
 *
 * UserDir disable[d] username ...
 * UserDir enable[d] username ...
 *
 * If "disabled" has no other arguments, *all* ~ references are
 * disabled, except those explicitly turned on with the "enabled" keyword.

/* mod_speling.c - by Alexei Kosut  June, 1996
 *
 * This module is transparent, and simple. It attempts to correct
 * misspellings of URLs that users might have entered, namely by checking
 * capitalizations. If it finds a match, it sends a redirect.
 *
 * Sep-1999 Hugo Haas 
 * o Added a CheckCaseOnly option to check only miscapitalized words.
 *
 * 08-Aug-1997 
 * o Upgraded module interface to apache_1.3a2-dev API (more NULL's in
 *   speling_module).
 * o Integrated tcsh's "spelling correction" routine which allows one
 *   misspelling (character insertion/omission/typo/transposition).
 *   Rewrote it to ignore case as well. This ought to catch the majority
 *   of misspelled requests.
 * o Commented out the second pass where files' suffixes are stripped.
 *   Given the better hit rate of the first pass, this rather ugly
 *   (request index.html, receive index.db ?!?!) solution can be
 *   omitted.
 * o wrote a "kind of" html page for mod_speling
 *
 * Activate it with "CheckSpelling On"

 *
 *  URL Rewriting Module
 *
 *  This module uses a rule-based rewriting engine (based on a
 *  regular-expression parser) to rewrite requested URLs on the fly.
 *
 *  It supports an unlimited number of additional rule conditions (which can
 *  operate on a lot of variables, even on HTTP headers) for granular
 *  matching and even external database lookups (either via plain text
 *  tables, DBM hash files or even external processes) for advanced URL
 *  substitution.
 *
 *  It operates on the full URLs (including the PATH_INFO part) both in
 *  per-server context (httpd.conf) and per-dir context (.htaccess) and even
 *  can generate QUERY_STRING parts on result.   The rewriting result finally
 *  can lead to internal subprocessing, external request redirection or even
 *  to internal proxy throughput.
 *
 *  This module was originally written in April 1996 and
 *  gifted exclusively to the The Apache Software Foundation in July 1997 by
 *
 *      Ralf S. Engelschall

 * mod_actions.c: executes scripts based on MIME type or HTTP method
 *

 * adapted by rst from original NCSA code by Rob McCool
 *
 * Usage instructions:
 *
 * Action mime/type /cgi-bin/script
 *
 * will activate /cgi-bin/script when a file of content type mime/type is
 * requested. It sends the URL and file path of the requested document using
 * the standard CGI PATH_INFO and PATH_TRANSLATED environment variables.
 *
 * Script PUT /cgi-bin/script
 *
 * will activate /cgi-bin/script when a request is received with the
 * HTTP method "PUT".  The available method names are defined in httpd.h.
 * If the method is GET, the script will only be activated if the requested
 * URI includes query information (stuff after a ?-mark).

/*
 * This imagemap module started as a port of the original imagemap.c
 * written by Rob McCool (11/13/93 robm@ncsa.uiuc.edu).
 * This version includes the mapping algorithms found in version 1.3
 * of imagemap.c.
 *
 * Contributors to this code include:
 *
 * Kevin Hughes, kevinh@pulua.hcc.hawaii.edu
 *
 * Eric Haines, erich@eye.com
 * "macmartinized" polygon code copyright 1992 by Eric Haines, erich@eye.com
 *
 * Randy Terbush, randy@zyzzyva.com
 * port to Apache module format, "base_uri" and support for relative URLs
 *
 * James H. Cloos, Jr., cloos@jhcloos.com
 * Added point datatype, using code in NCSA's version 1.8 imagemap.c
 * program, as distributed with version 1.4.1 of their server.
 * The point code is originally added by Craig Milo Rogers, Rogers@ISI.Edu
 *
 * Nathan Kurz, nate@tripod.com
 * Rewrite/reorganization.  New handling of default, base and relative URLs.
 * New Configuration directives:
 *    ImapMenu {none, formatted, semiformatted, unformatted}
 *    ImapDefault {error, nocontent, referer, menu, URL}
 *    ImapBase {map, referer, URL}
 * Support for creating non-graphical menu added.  (backwards compatible):
 *    Old:  directive URL [x,y ...]
 *    New:  directive URL "Menu text" [x,y ...]
 *     or:  directive URL x,y ... "Menu text"
 * Map format and menu concept courtesy Joshua Bell, jsbell@acs.ucalgary.ca.
 *
 * Mark Cox, mark@ukweb.com, Allow relative URLs even when no base specified

     *    credentials that are in the store (or missing there).
     *    Expiry times, MD state, etc.
     * 8. Determine the list of MDs that need driving/supervision.
     * 9. Cleanup any left-overs in registry/store that are no longer needed for
     *    the list of MDs as we know it now.
     * 10. If this list is non-empty, setup a watchdog to run.

 * mod_isapi.c - Internet Server Application (ISA) module for Apache

 *
 * This module implements the ISAPI Handler architecture, allowing
 * Apache to load Internet Server Applications (ISAPI extensions),
 * similar to the support in IIS, Zope, O'Reilly's WebSite and others.
 *
 * It is a complete implementation of the ISAPI 2.0 specification,

 * asynchronous I/O.  It is further extended to include additional
 * "Microsoft extensions" through IIS 5.0, with some deficiencies
 * where one-to-one mappings don't exist.
 *
 * Refer to /manual/mod/mod_isapi.html for additional details on
 * configuration and use, but check this source for specific support
 * of the API,

/*
 * based on mod_tls.c - Apache SSL/TLS module for NetWare by Mike Gardiner.
 *
 * This module gives Apache the ability to do SSL/TLS with a minimum amount
 * of effort.  All of the SSL/TLS logic is already on NetWare versions 5 and
 * above and is interfaced through WinSock on NetWare.  As you can see in
 * the code below SSL/TLS sockets can be created with three WinSock calls.
 *
 * To load, simply place the module in the modules directory under the main
 * apache tree.  Then add a "SecureListen" with two arguments.  The first
 * argument is an address and/or port.  The second argument is the key pair
 * name as created in ConsoleOne.
 *
 *  Examples:
 *
 *          SecureListen 443 "SSL CertificateIP"
 *          SecureListen 123.45.67.89:443 mycert
 *
 * The module also supports RFC 2817 / TLS Upgrade for HTTP 1.1.
 * For this add a "NWSSLUpgradeable" with two arguments.  The first
 * argument is an address and/or port.  The second argument is the key pair
 * name as created in ConsoleOne.
 *
 *  Examples:
 *
 *          NWSSLUpgradeable 8080 "SSL CertificateIP"
 *          NWSSLUpgradeable 123.45.67.89:8080 mycert
 *

/*
 * Apache example_hooks module.  Provide demonstrations of how modules do things.
 * It is not meant to be used in a production server.  Since it participates
 * in all of the processing phases, it could conceivable interfere with
 * the proper operation of other modules -- particularly the ones related
 * to security.
 *
 * In the interest of brevity, all functions and structures internal to
 * this module, but which may have counterparts in *real* modules, are
 * prefixed with 'x_' instead of 'example_'.
 *
 * To use mod_example_hooks, configure the Apache build with
 * --enable-example-hooks and compile.  Set up a  block in your
 * configuration file like so:
 *
 * 
 *    SetHandler example-hooks-handler
 * 
 *
 * When you look at that location on your server, you will see a backtrace of
 * the callbacks that have been invoked up to that point.  See the ErrorLog for
 * more information on code paths that  touch mod_example_hooks.
 *
 * IMPORTANT NOTES
 * ===============
 *
 * Do NOT use this module on a production server. It attaches itself to every
 * phase of the server runtime operations including startup, shutdown and
 * request processing, and produces copious amounts of logging data.  This will
 * negatively affect server performance.
 *
 * Do NOT use mod_example_hooks as the basis for your own code.  This module
 * implements every callback hook offered by the Apache core, and your
 * module will almost certainly not have to implement this much.  If you
 * want a simple module skeleton to start development, use apxs -g.
 *
 * XXX TO DO XXX
 * =============
 *
 * * Enable HTML backtrace entries for more callbacks that are not directly
 *   associated with a request
 * * Make sure every callback that posts an HTML backtrace entry does so in the *   right category, so nothing gets overwritten
 * * Implement some logic to show what happens in the parent, and what in the
 *   child(ren)

[April, 1997, updated May 2000]

The files in the src/modules/examples directory under the Apache
distribution directory tree are provided as an example to those that
wish to write modules that use the Apache API.

The main file is mod_example_hooks.c, which illustrates all the different
callback mechanisms and call syntaces.  By no means does an add-on
module need to include routines for all of the callbacks - quite the
contrary!

The example module is an actual working module.  If you link it into
your server, enable the "example-hooks-handler" handler for a location,
and then browse to that location, you will see a display of some of the
tracing the example module did as the various callbacks were made.

To include the example module in your server add --enable-example-hooks
to the other ./configure arguments executed from the httpd source tree.
After that run 'make'.

To add another module of your own:

    A. cp modules/examples/mod_example_hooks.c modules/examples/mod_myexample.c
    B. Modify the file
    C. Add an entry to modules/examples/config.m4, e.g.
         APACHE_MODULE(myexample, my new module, , , no)
       The last argument specifies if the module is built by-default
    D. Build the server with --enable-myexample

For windows, the process is slightly different;

    A. copy modules\examples\mod_example_hooks.c modules\examples\mod_myexample.c
    B. copy modules\examples\mod_example_hooks.dsp modules\examples\mod_myexample.dsp
    C. replace the occurrences of 'example_hooks' with your module name.
    D. add the new .dsp to your Apache.dsw workspace, with dependencies
       on the libapr, libaprutil and libhttpd projects.  With the newer
       Developer Studio 2002 through 2005, when you add the new .dsp
       file it will be converted to a .vcproj file.

To activate the example module, include a block similar to the
following in your httpd.conf file:

    
	SetHandler example-hooks-handler
    

As an alternative, you can put the following into a .htaccess file and
then request the file "test.example" from that location:

    AddHandler example-hooks-handler .example

After reloading/restarting your server, you should be able to browse
to this location and see the brief display mentioned earlier.
httpd-2.4.52/modules/examples/mod_example_ipc.c000644 000770 000024 00000030712 12661357032 021435 0ustar00seistaff000000 000000 /* Licensed to the Apache Software Foundation (ASF) under one or more

/*
 *  mod_example_ipc -- Apache sample module
 *
 * This module illustrates the use in an Apache 2.x module of the Interprocess
 * Communications routines that come with APR. It is example code, and not meant
 * to be used in a production server.
 *
 * To play with this sample module first compile it into a DSO file and install
 * it into Apache's modules directory by running:
 *
 *    $ /path/to/apache2/bin/apxs -c -i mod_example_ipc.c
 *
 * Then activate it in Apache's httpd.conf file for instance for the URL
 * /example_ipc in as follows:
 *
 *    #   httpd.conf
 *    LoadModule example_ipc_module modules/mod_example_ipc.so
 *    
 *    SetHandler example_ipc
 *    
 *
 * Then restart Apache via
 *
 *    $ /path/to/apache2/bin/apachectl restart
 *
 * The module allocates a counter in shared memory, which is incremented by the
 * request handler under a mutex. After installation, activate the handler by
 * hitting the URL configured above with ab at various concurrency levels to see
 * how mutex contention affects server performance.

/* Here we deal with getting the request message body from the client.

 *
 * Note that this is more complicated than it was in Apache 1.1 and prior
 * versions, because chunked support means that the module does less.
 *
 * The proper procedure is this:
 *
 * 1. Call ap_setup_client_block() near the beginning of the request
 *    handler. This will set up all the necessary properties, and will
 *    return either OK, or an error code. If the latter, the module should
 *    return that error code. The second parameter selects the policy to
 *    apply if the request message indicates a body, and how a chunked
 *    transfer-coding should be interpreted. Choose one of
 *
 *    REQUEST_NO_BODY          Send 413 error if message has any body
 *    REQUEST_CHUNKED_ERROR    Send 411 error if body without Content-Length
 *    REQUEST_CHUNKED_DECHUNK  If chunked, remove the chunks for me.
 *    REQUEST_CHUNKED_PASS     If chunked, pass the chunk headers with body.
 *
 *    In order to use the last two options, the caller MUST provide a buffer
 *    large enough to hold a chunk-size line, including any extensions.
 *
 * 2. When you are ready to read a body (if any), call ap_should_client_block().
 *    This will tell the module whether or not to read input. If it is 0,
 *    the module should assume that there is no message body to read.
 *
 * 3. Finally, call ap_get_client_block in a loop. Pass it a buffer and its size.
 *    It will put data into the buffer (not necessarily a full buffer), and
 *    return the length of the input block. When it is done reading, it will
 *    return 0 if EOF, or -1 if there was an error.
 *    If an error occurs on input, we force an end to keepalive.
 *
 *    This step also sends a 100 Continue response to HTTP/1.1 clients if appropriate.

Specifically, it supports the protocols "h2" (HTTP2 over TLS) and "h2c" 
(HTTP2 over plain HTTP connections via Upgrade). Additionally it offers
the "direct" mode for both encrypted and unencrypted connections.

You may enable it for the whole server or specific virtual hosts only. 


BUILD

If you have libnghttp2 (https://nghttp2.org) installed on your system, simply
add 

    --enable-http2

to your httpd ./configure invocation. Should libnghttp2 reside in a unusual
location, add

    --with-nghttp2=

to ./configure.  is expected to be the installation prefix, so there
should be a /lib/libnghttp2.*. If your system support pkg-config,
/lib/pkgconfig/libnghttp2.pc will be inspected.

If you want to link nghttp2 statically into the mod_http2 module, you may
similarly to mod_ssl add

    --enable-nghttp2-staticlib-deps

For this, the lib directory should only contain the libnghttp2.a, not its
shared cousins.


CONFIGURATION

If mod_http2 is enabled for a site or not depends on the new "Protocols"
directive. This directive list all protocols enabled for a server or
virtual host.

If you do not specify "Protocols" all available protocols are enabled. For
sites using TLS, the protocol supported by mod_http2 is "h2". For cleartext
http:, the offered protocol is "h2c".

The following is an example of a server that only supports http/1.1 in
general and offers h2 for a specific virtual host.

    ...
    Protocols http/1.1
    
        Protocols h2 http/1.1
        ...
    

Please see the documentation of mod_http2 for a complete list and explanation 
of all options.


TLS CONFIGURATION

If you want to use HTTP/2 with a browser, most modern browsers will support
it without further configuration. However, browsers so far only support
HTTP/2 over TLS and are especially picky about the certificate and
encryption ciphers used.

Server admins may look for up-to-date information about "modern" TLS
compatibility under:

/**
 * A h2_task fakes a HTTP/1.1 request from the data in a HTTP/2 stream 
 * (HEADER+CONT.+DATA) the module receives.
 *
 * In order to answer a HTTP/2 stream, we want all Apache httpd infrastructure
 * to be involved as usual, as if this stream can as a separate HTTP/1.1
 * request. The basic trickery to do so was derived from google's mod_spdy
 * source. Basically, we fake a new conn_rec object, even with its own
 * socket and give it to ap_process_connection().
 *
 * Since h2_task instances are executed in separate threads, we may have
 * different lifetimes than our h2_stream or h2_session instances. Basically,
 * we would like to be as standalone as possible.
 *
 * Finally, to keep certain connection level filters, such as ourselves and
 * especially mod_ssl ones, from messing with our data, we need a filter
 * of our own to disable those.

 * The H2_PING connection sub-state: a state independant of the H2_SESSION state
 * of the connection:
 * - H2_PING_ST_NONE: no interference with request handling, ProxyTimeout in effect.
 *   When entered, all suspended streams are unsuspended again.
 * - H2_PING_ST_AWAIT_ANY: new requests are suspended, a possibly configured "ping"
 *   timeout is in effect. Any frame received transits to H2_PING_ST_NONE.
 * - H2_PING_ST_AWAIT_PING: same as above, but only a PING frame transits 
 *   to H2_PING_ST_NONE.
 *
 * An AWAIT state is entered on a new connection or when re-using a connection and
 * the last frame received has been some time ago. The latter sends a PING frame
 * and insists on an answer, the former is satisfied by any frame received from the
 * backend.
 *
 * This works for new connections as there is always at least one SETTINGS frame
 * that the backend sends. When re-using connection, we send a PING and insist on
 * receiving one back, as there might be frames in our connection buffers from
 * some time ago. Since some servers have protections against PING flooding, we
 * only ever have one PING unanswered.
 *
 * Requests are suspended while in a PING state, as we do not want to send data
 * before we can be reasonably sure that the connection is working (at least on
 * the h2 protocol level). This also means that the session can do blocking reads
 * when expecting PING answers.

 * push diary

 * - The push diary keeps track of resources already PUSHed via HTTP/2 on this
 *   connection. It records a hash value from the absolute URL of the resource
 *   pushed.
 * - Lacking openssl, 
 * - with openssl, it uses SHA256 to calculate the hash value, otherwise it
 *   falls back to apr_hashfunc_default()
 * - whatever the method to generate the hash, the diary keeps a maximum of 64
 *   bits per hash, limiting the memory consumption to about 
 *      H2PushDiarySize * 8 
 *   bytes. Entries are sorted by most recently used and oldest entries are
 *   forgotten first.
 * - While useful by itself to avoid duplicated PUSHes on the same connection,
 *   the original idea was that clients provided a 'Cache-Digest' header with
 *   the values of *their own* cached resources. This was described in
 *    
 *   and some subsequent revisions that tweaked values but kept the overall idea.
 * - The draft was abandoned by the IETF http-wg, as support from major clients,
 *   e.g. browsers, was lacking for various reasons.
 * - For these reasons, mod_h2 abandoned its support for client supplied values
 *   but keeps the diary. It seems to provide value for applications using PUSH,
 *   is configurable in size and defaults to a very moderate amount of memory
 *   used.
 * - The cache digest header is a Golomb Coded Set of hash values, but it may
 *   limit the amount of bits per hash value even further. For a good description
 *   of GCS, read here:

/**
 * A h2_bucket_beam solves the task of transferring buckets, esp. their data,
 * across threads with zero buffer copies.
 *
 * When a thread, let's call it the sender thread, wants to send buckets to
 * another, the green thread, it creates a h2_bucket_beam and adds buckets
 * via the h2_beam_send(). It gives the beam to the green thread which then
 * can receive buckets into its own brigade via h2_beam_receive().
 *
 * Sending and receiving can happen concurrently.
 *
 * The beam can limit the amount of data it accepts via the buffer_size. This
 * can also be adjusted during its lifetime. Sends and receives can be done blocking. 
 * A timeout can be set for such blocks.
 *
 * Care needs to be taken when terminating the beam. The beam registers at
 * the pool it was created with and will cleanup after itself. However, if
 * received buckets do still exist, already freed memory might be accessed.
 * The beam does a assertion on this condition.
 * 
 * The proper way of shutting down a beam is to first make sure there are no
 * more green buckets out there, then cleanup the beam to purge eventually
 * still existing sender buckets and then, possibly, terminate the beam itself
 * (or the pool it was created with).
 *
 * The following restrictions apply to bucket transport:
 * - only EOS and FLUSH meta buckets are copied through. All other meta buckets
 *   are kept in the beams hold.
 * - all kind of data buckets are transported through:
 *   - transient buckets are converted to heap ones on send
 *   - heap and pool buckets require no extra handling
 *   - buckets with indeterminate length are read on send
 *   - file buckets will transfer the file itself into a new bucket, if allowed
 *   - all other buckets are read on send to make sure data is present
 *
 * This assures that when the sender thread sends its sender buckets, the data
 * is made accessible while still on the sender side. The sender bucket then enters
 * the beams hold storage.
 * When the green thread calls receive, sender buckets in the hold are wrapped
 * into special beam buckets. Beam buckets on read present the data directly
 * from the internal sender one, but otherwise live on the green side. When a
 * beam bucket gets destroyed, it notifies its beam that the corresponding
 * sender bucket from the hold may be destroyed.
 * Since the destruction of green buckets happens in the green thread, any
 * corresponding sender bucket can not immediately be destroyed, as that would
 * result in race conditions.
 * Instead, the beam transfers such sender buckets from the hold to the purge
 * storage. Next time there is a call from the sender side, the buckets in
 * purge will be deleted.
 *
 * There are callbacks that can be registesender with a beam:
 * - a "consumed" callback that gets called on the sender side with the
 *   amount of data that has been received by the green side. The amount
 *   is a delta from the last callback invocation. The sender side can trigger
 *   these callbacks by calling h2_beam_send() with a NULL brigade.
 * - a "can_beam_file" callback that can prohibit the transfer of file handles
 *   through the beam. This will cause file buckets to be read on send and
 *   its data buffer will then be transports just like a heap bucket would.
 *   When no callback is registered, no restrictions apply and all files are
 *   passed through.
 *   File handles transfersender to the green side will stay there until the
 *   receiving brigade's pool is destroyed/cleared. If the pool lives very
 *   long or if many different files are beamed, the process might run out
 *   of available file handles.
 *
 * The name "beam" of course is inspired by good old transporter
 * technology where humans are kept inside the transporter's memory
 * buffers until the transmission is complete. Star gates use a similar trick.

/**
 * A HTTP/2 connection, a session with a specific client.
 * 
 * h2_session sits on top of a httpd conn_rec* instance and takes complete
 * control of the connection data. It receives protocol frames from the
 * client. For new HTTP/2 streams it creates h2_task(s) that are sent
 * via callback to a dispatcher (see h2_conn.c).
 * h2_session keeps h2_io's for each ongoing stream which buffer the
 * payload for that stream.
 *
 * New incoming HEADER frames are converted into a h2_stream+h2_task instance
 * that both represent a HTTP/2 stream, but may have separate lifetimes. This
 * allows h2_task to be scheduled in other threads without semaphores
 * all over the place. It allows task memory to be freed independent of
 * session lifetime and sessions may close down while tasks are still running.

         * some modules (and maybe external code) uses this id as an identifier
         * for the request_rec they handle, it needs to be unique for secondary 
         * connections also.
         *
         * The MPM module assigns the connection ids and mod_unique_id is using
         * that one to generate identifier for requests. While the implementation
         * works for HTTP/1.x, the parallel execution of several requests per
         * connection will generate duplicate identifiers on load.
         * 
         * The original implementation for secondary connection identifiers used 
         * to shift the master connection id up and assign the stream id to the 
         * lower bits. This was cramped on 32 bit systems, but on 64bit there was
         * enough space.
         * 
         * As issue 195 showed, mod_unique_id only uses the lower 32 bit of the
         * connection id, even on 64bit systems. Therefore collisions in request ids.
         *
         * The way master connection ids are generated, there is some space "at the
         * top" of the lower 32 bits on allmost all systems. If you have a setup
         * with 64k threads per child and 255 child processes, you live on the edge.
         *
         * The new implementation shifts 8 bits and XORs in the worker
         * id. This will experience collisions with > 256 h2 workers and heavy
         * load still. There seems to be no way to solve this in all possible 
         * configurations by mod_h2 alone.

/*
 * mod_auth_digest: MD5 digest authentication
 *
 * Originally by Alexei Kosut 
 * Updated to RFC-2617 by Ronald Tschal�r 
 * based on mod_auth, by Rob McCool and Robert S. Thau
 *
 * This module an updated version of modules/standard/mod_digest.c
 * It is still fairly new and problems may turn up - submit problem
 * reports to the Apache bug-database, or send them directly to me
 * at ronald@innovation.ch.
 *
 * Open Issues:
 *   - qop=auth-int (when streams and trailer support available)
 *   - nonce-format configurability
 *   - Proxy-Authorization-Info header is set by this module, but is
 *     currently ignored by mod_proxy (needs patch to mod_proxy)
 *   - The source of the secret should be run-time directive (with server
 *     scope: RSRC_CONF)
 *   - shared-mem not completely tested yet. Seems to work ok for me,
 *     but... (definitely won't work on Windoze)
 *   - Sharing a realm among multiple servers has following problems:
 *     o Server name and port can't be included in nonce-hash
 *       (we need two nonce formats, which must be configured explicitly)
 *     o Nonce-count check can't be for equal, or then nonce-count checking
 *       must be disabled. What we could do is the following:
 *       (expected < received) ? set expected = received : issue error
 *       The only problem is that it allows replay attacks when somebody
 *       captures a packet sent to one server and sends it to another
 *       one. Should we add "AuthDigestNcCheck Strict"?
 *   - expired nonces give amaya fits.
 *   - MD5-sess and auth-int are not yet implemented. An incomplete
 *     implementation has been removed and can be retrieved from svn history.

/*
 * client list code
 *
 * Each client is assigned a number, which is transferred in the opaque
 * field of the WWW-Authenticate and Authorization headers. The number
 * is just a simple counter which is incremented for each new client.
 * Clients can't forge this number because it is hashed up into the
 * server nonce, and that is checked.
 *
 * The clients are kept in a simple hash table, which consists of an
 * array of client_entry's, each with a linked list of entries hanging
 * off it. The client's number modulo the size of the array gives the
 * bucket number.
 *
 * The clients are garbage collected whenever a new client is allocated
 * but there is not enough space left in the shared memory segment. A
 * simple semi-LRU is used for this: whenever a client entry is accessed
 * it is moved to the beginning of the linked list in its bucket (this
 * also makes for faster lookups for current clients). The garbage
 * collecter then just removes the oldest entry (i.e. the one at the
 * end of the list) in each bucket.
 *
 * The main advantages of the above scheme are that it's easy to implement
 * and it keeps the hash table evenly balanced (i.e. same number of entries
 * in each bucket). The major disadvantage is that you may be throwing
 * entries out which are in active use. This is not tragic, as these
 * clients will just be sent a new client id (opaque field) and nonce
 * with a stale=true (i.e. it will just look like the nonce expired,
 * thereby forcing an extra round trip). If the shared memory segment
 * has enough headroom over the current client set size then this should
 * not occur too often.
 *
 * To help tune the size of the shared memory segment (and see if the
 * above algorithm is really sufficient) a set of counters is kept
 * indicating the number of clients held, the number of garbage collected
 * clients, and the number of erroneously purged clients. These are printed
 * out at each garbage collection run. Note that access to the counters is
 * not synchronized because they are just indicaters, and whether they are
 * off by a few doesn't matter; and for the same reason no attempt is made
 * to guarantee the num_renewed is correct in the face of clients spoofing
 * the opaque field.
 */

/*
 * Get the client given its client number (the key). Returns the entry,
 * or NULL if it's not found.
 *
 * Access to the list itself is synchronized via locks. However, access
 * to the entry returned by get_client() is NOT synchronized. This means
 * that there are potentially problems if a client uses multiple,
 * simultaneous connections to access url's within the same protection
 * space. However, these problems are not new: when using multiple
 * connections you have no guarantee of the order the requests are
 * processed anyway, so you have problems with the nonce-count and
 * one-time nonces anyway.

/**
 * This module makes it easy to restrict what HTTP methods can be ran against
 * a server.
 *
 * It provides one command:
 *    AllowMethods
 * This command takes a list of HTTP methods to allow.
 *
 *  The most common configuration should be like this:
 *   
 *    AllowMethods GET HEAD OPTIONS
 *   
 *   
 *      AllowMethods GET HEAD OPTIONS POST
 *   
 *  Non-matching methods will be returned a status 405 (method not allowed)
 *
 *  To allow all methods, and effectively turn off mod_allowmethods, use:
 *    AllowMethods reset

 * Adapted to allow anonymous logins, just like with Anon-FTP, when
 * one gives the magic user name 'anonymous' and ones email address
 * as the password.
 *
 * Just add the following tokes to your  setup:
 *
 * Anonymous                    magic-userid [magic-userid]...
 *
 * Anonymous_MustGiveEmail      [ on | off ] default = on
 * Anonymous_LogEmail           [ on | off ] default = on
 * Anonymous_VerifyEmail        [ on | off ] default = off
 * Anonymous_NoUserId           [ on | off ] default = off
 *
 * The magic user id is something like 'anonymous', it is NOT case sensitive.
 *
 * The MustGiveEmail flag can be used to force users to enter something
 * in the password field (like an email address). Default is on.
 *
 * Furthermore the 'NoUserID' flag can be set to allow completely empty
 * usernames in as well; this can be is convenient as a single return
 * in broken GUIs like W95 is often given by the user. The Default is off.

** Apache HTTPD 2.4 ( http://httpd.apache.org/ ) or higher

* Documentation
  See docs/README

* Building
  For now, see docs/building-from-subversion.txt


* Task List
** TODO Use r->file to determine file, doing rewriting in translate_name   
** TODO Provide means to get useful output from lua errors in response body
   Probably have to put it on the vm spec for pre-handler errors, as
   it is pre-handler, will prolly be on the request_config somewhere,
   but sometimes cannot put there, so... fun
** TODO Mapping in the server_rec
** TODO Figure out how reentrancy works regarding filter chain stuff. 
   Do we need new "threads"?
** TODO: Flatten LuaHook* to LuaHook phase file fn ?
** TODO: document or remove block sections
** TODO: test per-dir behavior of block sections
** TODO: Suppress internal details (fs path to scripts, etc) in error responses
** TODO: Check whether we can tighten the mode flag in lua_load(),
         luaL_loadfile() an dluaL_loadbuffer() from NULL (="bt")
         to e.g. "t".

    http://www.lua.org/download.html
    
    Lua does not use autoconf for compiling. This means that you do not use
    ./configure. It has good build instructions, though, so hopefully things
    will go smoothly.
    
    I like to change the directory Lua installs to. In order to do this you
    need to set LUA_TOP in the configuration makefile for Lua. For these 
    instructions I have set LUA_TOP to /Users/brianm/.opt/lua-5.1.2 -- you
    will see this directory referred to later.
    
    
Install Apache HTTPD 2.2
    http://httpd.apache.org/download.cgi
    
    You can build apache pretty much any way you like, as long as you enable
    dynamic module loading (--enable-so) so that mod_wombat can be loaded.
    
    You may user (and I encourage you to!) the threaded MPMs -- mod_wombat
    plays nicely with them.

    I build it with these flags:
        
    ./configure --prefix=/Users/brianm/.opt/httpd-2.2.4-worker-wombat \
                --with-mpm=worker  \
                --enable-so
    
    
Install libapreq2
    http://httpd.apache.org/apreq/download.cgi
        The download link is in the page body, NOT under the "Download!" link
        in the left hand column.
    
    Right now, mod_wombat requires libapreq2 for parsing entity bodies. This
    dependency will probably be made optional in the near future, but for now
    you need it.
    
    I build it with these flags:
    
    ./configure --prefix=/Users/brianm/.opt/libapreq2-2.0.8 \
      --with-apache2-apxs=/Users/brianm/.opt/httpd-2.2.4-worker-wombat/bin/apxs
    
    
Install mod_wombat from subversion
    http://svn.apache.org/repos/asf/httpd/mod_wombat/trunk
    
    The first step, when building from subversion, is to bootstrap autoconf. 
    To do this run the bootstrap script:
    
    ./bootstrap
    
    The bootstrap script may report an error that it cannot find
    libtoolize or glibtoolize. That is fine as long as it 
    doesn't report that it cannot find both of them. The script
    just sets up the autoconf magic. 
    
    After that, it is a normal configure and build:
    
    ./configure  --with-lua=/Users/brianm/.opt/lua-5.1.2/ \
      --with-apxs=/Users/brianm/.opt/httpd-2.2.4-worker-wombat/bin/apxs \
      --with-apreq2=/Users/brianm/.opt/libapreq2-2.0.8/
      
    If compiling (make) reports an error that it cannot find the
    libapreq2 header file, please tell me ( brianm@apache.org )
    as this occurs under some configurations but we haven't 
    hammered down the weird things libapreq2 does with its
    install. If you build libapreq2 with a --prefix configuration
    option, it always seems to work.
  
      
That is it. To configure mod_wombat, look at the basic-configuration.txt document.httpd-2.4.52/modules/lua/docs/running-developer-tests.txt000644 000770 000024 00000001011 11366570643 023377 0ustar00seistaff000000 000000 -*- mode:org -*-
* Building mod_lua
  The first step is to build mod_lua per the instructions in
  building-from-subversion.txt.

* Build and install LuaSocket
    http://www.cs.princeton.edu/~diego/professional/luasocket/
    FreeBSD: /usr/ports/net/luasocket

* Running Tests
  1. Replace apache's httpd.conf with test/test_httpd.conf
  2. Customize the new httpd.conf to match your directories
  3. Finally, to run the tests, start apache and run:
     $ cd test
     $ lua ./test.lua
     FreeBSD: lua-5.1 ./test.lua

just evaluating a script body CGI style. A handler function looks
something like this:

    -- example.lua --
    require "string"

    function handle_something(r)
        r.content_type = "text/plain"
        r:puts("Hello Lua World!\n")
    
        if r.method == 'GET' then
            for k, v in pairs( r:parseargs() ) do
                r:puts( string.format("%s: %s", k, v) )
            end
        elseif r.method == 'POST' then
            for k, v in pairs( r:parsebody() ) do
                r:puts( string.format("%s: %s", k, v) )
            end
        else
            r:puts("unknown HTTP method " .. r.method)
        end 
    end

This handler function just prints out the uri or form encoded
arguments to a plaintext page.

This means (and in fact encourages) that you can have multiple
handlers (or hooks, or filters) in the same script.

Data Structures:
    request_rec:
        the request_rec is mapped in as a userdata. It has a metatable
        which lets you do useful things with it. For the most part it
        has the same fields as the request_rec struct (see httpd.h 
        until we get better docs here) many of which are writeable as
        well as readable, and has (at least) the following methods:
        
        r:puts("hello", " world", "!") -- print to response body
        
        -- logging functions
        r:debug("This is a debug log message")
        r:info("This is an info log message")
        r:notice("This is an notice log message")
        r:warn("This is an warn log message")
        r:err("This is an err log message")
        r:alert("This is an alert log message")
        r:crit("This is an crit log message")
        r:emerg("This is an emerg log message")
httpd-2.4.52/modules/lua/docs/basic-configuration.txt000644 000770 000024 00000013023 11376506251 022523 0ustar00seistaff000000 000000 See sample_httpd.conf for examples

The basic module loading directive is
    LoadModule lua_module modules/mod_lua.so

The handler name is "lua-script" so you can use the normal
AddHandler directive, such as "AddHandler lua-script .lua" to
set anything ending in .lua to use mod_lua to evaluate

mod_lua exports several additional directives:

    LuaRoot /path/to/a/directory
        Specify the base path which will be used to evaluate all
        relative paths within mod_lua. If not specified they
        will be resolved relative to the current working directory,
        which may not always work well for a server.

    LuaScope once|request|conn|server [max|min max]
        Specify the lifecycle scope of the Lua interpreter which will
        be used by handlers in this "Directory." The default is "once"
        
        once: use the interpreter once and throw it away.
        
        request: use the interpreter to handle anything based on 
                 the same file within this request, which is also 
                 request scoped.
                 
        conn: Same as request but attached to the connection_rec
        
        server: This one is different than others because the
                server scope is quite long lived, and multiple threads
                will have the same server_rec. To accommodate this
                server scoped interpreter are stored in an apr
                resource list. The min and max arguments are intended
                to specify the pool size, but are unused at this time.

    LuaMapHandler uri-pattern /path/to/lua/script.lua [function-name]
        This directive matches a uri pattern to invoke a specific
        handler function in a specific file. It uses PCRE regular
        expressions to match the uri, and supports interpolating
        match groups into both the file path and the function name
        be careful writing your regular expressions to avoid security
        issues.
        
        Examples:
            LuaMapHandler /(\w+)/(/w+) /scripts/$1.lua handle_$2
                This would match uri's such as /photos/show?id=9
                to the file /scripts/photos.lua and invoke the
                handler function handle_show on the lua vm after
                loading that file.
                
            LuaMapHandler /bingo /scripts/wombat.lua
                This would invoke the "handle" function, which
                is the default if no specific function name is
                provided.
    
    LuaPackagePath /path/to/include/?.lua
        Add a path to lua's module search path. Follows the same
        conventions as lua. This just munges the package.path in the 
        lua vms.
        
        Examples:
            LuaPackagePath /scripts/lib/?.lua
            LuaPackagePath /scripts/lib/?/init.lua

    LuaPackageCPath /path/to/include/?.soa
        Add a path to lua's shared library search path. Follows the same
        conventions as lua. This just munges the package.cpath in the 
        lua vms.
        
        Examples:
            LuaPackagePath /scripts/lib/?.so

    LuaCodeCache stat|forever|never
        Specify the behavior of the in-memory code cache. The default
        is stat, which stats the top level script (not any included
        ones) each time that file is needed, and reloads it if the
        modified time indicates it is newer than the one it has
        already loaded. The other values cause it to keep the file
        cached forever (don't stat and replace) or to never cache the 
        file.
        
        In general stat or forever is good production and stat or never
        for development.
        
        Examples:
            LuaCodeCache stat
            LuaCodeCache forever
            LuaCodeCache never
    
    LuaHookTranslateName  /path/to/lua/script.lua  hook_function_name
        Add a hook (at APR_HOOK_MIDDLE) to the translate name phase of
        request processing. The hook function receives a single
        argument, the request_rec, and should return a status code, 
        which is either an HTTP error code, or the constants defined
        in the apache2 module: apache2.OK, apache2.DECLINED, or
        apache2.DONE. 

        For those new to hooks, basically each hook will be invoked
        until one of them returns apache2.OK. If your hook doesn't
        want to do the translation it should just return
        apache2.DECLINED. If the request should stop processing, then
        return apache2.DONE.

        Example:
            LuaHookTranslateName /scripts/conf/hooks.lua silly_mapper

            -- /scripts/conf/hooks.lua --
            function silly_mapper(r)
                if r.uri == "/" then
                    r.file = "/var/www/home.lua"
                    return apache2.OK
                else
                    return apache2.DECLINED
                end
            end

- Building on generic Unix:

  Add generic ldap support and the TWO ldap modules to the build, like this:

  ./configure --with-ldap --enable-ldap --enable-authnz-ldap

  The --with-ldap switches on LDAP library linking in apr-util. Make
  sure that you have an LDAP client library available such as those
  from Netscape/iPlanet/Sun One or the OpenLDAP project.

  The --enable-ldap option switches on the LDAP caching module. This
  module is a support module for other LDAP modules, and is not useful
  on its own.  This module is required, but caching can be disabled
  via the configuration directive LDAPCacheEntries.

  The --enable-auth-ldap option switches on the LDAP authentication
  module.

- Building on AIX:

  The following ./configure line is reported to work for AIX:

    CC=cc_r; export CC
    CPPFLAGS=-qcpluscmt;export CPPFLAGS
    ./configure --with-mpm=worker --prefix=/usr/local/apache \
      --enable-dav=static --enable-dav_fs=static --enable-ssl=static
      --with-ldap=yes --with-ldap-include=/usr/local/include
      --with-ldap-lib=/usr/local/lib --enable-ldap=static
      --enable-authnz-ldap=static


Quick installation instructions (win32):

1. copy the file srclib\apr-util\include\apr_ldap.hw to apr_ldap.h
2. the netscape/iplanet ldap libraries are installed in srclib\ldap
3. Compile the two modules util_ldap and mod_authnz_ldap using the dsp files
4. You get a mod_authnz_ldap.so and a mod_ldap.so module
5. Put them in the modules directory, don't forget to copy the
   nsldap32v50.dll somewhere where httpd.exe will find it
6. Load the two modules in your httpd.conf, like below:
   LoadModule ldap_module modules/mod_ldap.so
   LoadModule authnz_ldap_module modules/mod_authnz_ldap.so
7. Configure the directories as described in the docus.

 * Does a recursive lookup operation to try to find a user within (cached)

 * DON'T CALL THIS UNLESS YOU CALLED uldap_cache_compare FIRST!!!!!
 *
 *
 * 1. Call uldap_cache_compare for each subgroupclass value to check the
 *    generic, user-agnostic, cached group entry. This will create a new generic
 *    cache entry if there
 *    wasn't one. If nothing returns LDAP_COMPARE_TRUE skip to step 5 since we
 *    have no groups.
 * 2. Lock The cache and get the generic cache entry.
 * 3. Check if there is already a subgrouplist in this generic group's cache
 *    entry.
 *    A. If there is, go to step 4.
 *    B. If there isn't:
 *       i)   Use ldap_search to get the full list
 *            of subgroup "members" (which may include non-group "members").
 *       ii)  Use uldap_cache_compare to strip the list down to just groups.
 *       iii) Lock and add this stripped down list to the cache of the generic
 *            group.
 * 4. Loop through the sgl and call uldap_cache_compare (using the user info)
 *    for each
 *    subgroup to see if the subgroup contains the user and to get the subgroups
 *    added to the
 *    cache (with user-afinity, if they aren't already there).
 *    A. If the user is in the subgroup, then we'll be returning
 *       LDAP_COMPARE_TRUE.
 *    B. if the user isn't in the subgroup (LDAP_COMPARE_FALSE via
 *       uldap_cache_compare) then recursively call this function to get the

     * the first request comes back with either new content or confirmation
     * that the stale content is still fresh.
     *

     * the key of the cached object. We attempt to open the lock file with
     * exclusive write access. If we succeed, woohoo! we're first, and we
     * follow the stale path to the backend server. If we fail, oh well,
     * we follow the fresh path, and avoid being a thundering herd.
     *
     * The lock lives only as long as the stale request that went on ahead.
     * If the request succeeds, the lock is deleted. If the request fails,
     * the lock is deleted, and another request gets to make a new lock
     * and try again.
     *
     * At any time, a request marked "no-cache" will force a refresh,
     * ignoring the lock, ensuring an extended lockout is impossible.

/*
 * Author: mod_file_cache by Bill Stoddard 
 *         Based on mod_mmap_static by Dean Gaudet 
 *
 * v0.01: initial implementation
 */

/*
    Documentation:

    Some sites have a set of static files that are really busy, and
    change infrequently (or even on a regular schedule). Save time
    by caching open handles to these files. This module, unlike
    mod_mmap_static, caches open file handles, not file content.
    On systems (like Windows) with heavy system call overhead and
    that have an efficient sendfile implementation, caching file handles
    offers several advantages over caching content. First, the file system
    can manage the memory, allowing infrequently hit cached files to
    be paged out. Second, since caching open handles does not consume
    significant resources, it will be possible to enable an AutoLoadCache
    feature where static files are dynamically loaded in the cache
    as the server runs. On systems that have file change notification,
    this module can be enhanced to automatically garbage collect
    cached files that change on disk.

    This module should work on Unix systems that have sendfile. Place
    cachefile directives into your configuration to direct files to
    be cached.

        cachefile /path/to/file1
        cachefile /path/to/file2
        ...

    These files are only cached when the server is restarted, so if you
    change the list, or if the files are changed, then you'll need to
    restart the server.

    To reiterate that point:  if the files are modified *in place*
    without restarting the server you may end up serving requests that
    are completely bogus.  You should update files by unlinking the old
    copy and putting a new copy in place.

    There's no such thing as inheriting these files across vhosts or
    whatever... place the directives in the main server only.

    Known problems:

    Don't use Alias or RewriteRule to move these files around...  unless
    you feel like paying for an extra stat() on each request.  This is
    a deficiency in the Apache API that will hopefully be solved some day.
    The file will be served out of the file handle cache, but there will be
    an extra stat() that's a waste.

#define SHMCB_MAX_SIZE (UINT_MAXsubcache_num SHMCBSubcache
 * structures.  The hash table is indexed by SHMCB_MASK(id). Each
 * SHMCBSubcache structure has a fixed size (header->subcache_size),
 * which is determined at creation time, and looks like the following:
 *
 *   [ SHMCBSubcache | Indexes | Data ]
 *
 * Each subcache is prefixed by the SHMCBSubcache structure.
 *
 * The subcache's "Data" segment is a single cyclic data buffer, of
 * total size header->subcache_data_size; data inside is referenced
 * using byte offsets. The offset marking the beginning of the cyclic
 * buffer is subcache->data_pos; the buffer's length is
 * subcache->data_used.
 *
 * "Indexes" is an array of header->index_num SHMCBIndex structures,
 * which is used as a cyclic queue; subcache->idx_pos gives the array
 * index of the first in use, subcache->idx_used gives the number in
 * use.  Both ->idx_* values have a range of [0, header->index_num)
 *
 * Each in-use SHMCBIndex structure represents a single cached object.
 * The ID and data segment are stored consecutively in the subcache's
 * cyclic data buffer.  The "Data" segment can thus be seen to
 * look like this, for example
 *
 * offset:  [ 0     1     2     3     4     5     6    ...
 * contents:[ ID1   Data1       ID2   Data2       ID3  ...

 *
 * idx1 = { data_pos = 0, data_used = 3, id_len = 1, ...}
 * idx2 = { data_pos = 3, data_used = 3, id_len = 1, ...}

 * server, and behaves as a discrete RFC2616 caching proxy
 * implementation.
 *
 * Under certain circumstances, an admin might want to run the cache as
 * a normal handler instead of a quick handler, allowing the cache to
 * run after the authorisation hooks, or by allowing fine control over
 * the placement of the cache in the filter chain. This option comes at
 * a performance penalty, and should only be used to achieve specific
 * caching goals where the admin understands what they are doing.

* PLEASE NOTE: Now that development for  *
* mod_proxy has been folded back into    *
* the httpd-2.1 tree, this file has      *
* been deprecated. Proxy changes should *
* be noted in httpd-2.x's CHANGES file.  *
* This file exists for historical        *
* purposes.                              *
******************************************

mod_proxy changes for httpd 2.0.29-dev
  *) don't do keepalives for sub-requests. [Ian Holsman]
  
  *) fix up proxypass handling [Ian Holsman]

  *) don't send If-Modified-Since, Cache-Control, or If-None-Match on 
     a subrequest [Ian Holsman]

mod_proxy changes for httpd 2.0.26-dev
  *) Add New option 'HTTPProxyOverrideReturnedErrors'. By Turning the
     Flag on, you will mask the error pages returned by the proxied
     server, and will it will be handled as if your server generated
     the error. This change was put in so that a 404 on a included
     r-proxied component will act in the same manner as a 404 on a 
     included file. [Ian Holsman ]

mod_proxy changes for httpd 2.0.25-dev

  *) Split proxy: space using  directive blocks from
     the  and  blocks.  Mod_proxy
     now bypasses the directory and files testing phase (and skips 
     the http TRACE default handler on it's own, as well).  Note that 
      blocks continue to be processed for proxy: requests.
     [William Rowe ]

  *) apr_uri type/function namespace changes in apr_uri functions
     [Doug MacEachern ]

mod_proxy changes for httpd 2.0.23-dev

  *) break the proxy_http_handler into multiple smaller functions.
     [John Barbee ]

  *) Fix the proxy when the origin server sends back a 100
     Continue response.  [John Barbee ]

  *) Change 'readbytes' from apr_size_t to apr_off_t due to change
     in ap_get_brigade's parameters [John Barbee ]

mod_proxy changes for httpd 2.0.20-dev
  *) Timeout added for backend connections.
     [Victor Orlikowski ]

  *) Fix abort code path in proxy_http.c, similar to FTP fix.
     [Chuck Murcko ]

  *) Fix FTP ABOR command execution path.
     [Victor Orlikowski ]

  *) FTP return code variable cleanup; fixed problem in login
     [Chuck Murcko ]

  *) Get PORT working again in the ftp proxy.
     [Victor Orlikowski ]

  *) Return result code check for FTP QUIT, after fixing
     problems with passive connection handling.
     [Victor Orlikowski ]

  *) Reorganize ap_proxy_string_read() internally to not process eos
     buckets.
     [Chuck Murcko ]
     [Victor Orlikowski ]

  *) Remove result code check for FTP QUIT command. Some servers send
     nothing at all back in response to QUIT.
     [Chuck Murcko ]
     [Victor Orlikowski ]

mod_proxy changes for httpd 2.0.19

  *) Reverse previous patch since the core reverted.
     [Chuck Murcko ]

  *) Remove indirection on number of bytes to read for input filters.
     [Chuck Murcko ]

  *) Fixed a problem with directory listing corruption in the
     PROXY_DIR filter.
     [Graham Leggett ]

  *) mod_proxy and the proxy submodules now build properly as DSOs.
     [Graham Leggett ]

  *) Stopped the HTTP proxy from trying to read entity bodies when there
     wasn't one (response was 1xx, 204, 205 or 304).
     [Graham Leggett ]

  *) Made sure dates were canonicalised correctly when passed to the client
     browser through the HTTP proxy.
     [Graham Leggett ]

  *) Split each individual proxy protocol into separate modules.
     [Graham Leggett ]

  *) Added Max-Forwards support for all request types so as to prevent
     loops.
     [Graham Leggett ]

  *) Fix warnings about byte count type on Darwin (connect handler).
     [Chuck Murcko ]

mod_proxy changes for httpd 2.0.18

  *) IPV6 EPSV support for IPV6 in FTP proxy.
     [Graham Leggett ]

  *) FTP directory filter works now.
     [Graham Leggett ]

  *) Fixed some thread-safety issues with the HTTP proxy in mod_proxy.
     [Graham Leggett ]

  *) PASV FTP works now.
     [Graham Leggett ]

  *) Reworked the line-at-a-time read from the control connection to
     workaround a stray empty bucket returned by the HTTP_IN filter.
     [Graham Leggett ]

  *) Stopped the CORE filter from sending off an HTTP response when a
     CONNECT tunnel was closed.
     [Graham Leggett ]

  *) Fixed the poll() loop in proxy_connect.c -> it works now!!!
     [Graham Leggett ]

  *) Converted send_dir() to ap_proxy_send_dir_filter() in proxy_ftp.c.
     [Graham Leggett ]

mod_proxy changes for httpd 2.0.17

  *) Major rework of ap_proxy_ftp_handler() to use filters (begone foul
     BUFF!!!). It compiles, but is untested, and the build environment needs
     to be fixed to include proxy_ftp.c.
     [Graham Leggett ]

  *) Cleanup of dead functions within proxy_util.c.
     [Graham Leggett ]

  *) Reworked the storage of the client socket between keepalive connections
     to fix some nasty problems with the socket lasting longer than the
     memory pool it was allocated from.
     [Graham Leggett ]

  *) Fixed bug where a hostname without a "." in it (such as "localhost")
     would not trigger an IP address check with ProxyBlock.
     [Graham Leggett ]

mod_proxy changes for httpd 2.0.16

  *) Fixed ProxyBlock bugs with ap_proxy_http_handler() and
     ap_proxy_connect_handler().
     [Graham Leggett ]

  *) Updated ap_proxy_connect_handler() to support APR, while
     moving some common code between http_handler and connect_handler
     to proxy_util.c.
     [Graham Leggett ]

  *) Updated mod_proxy.html docs to include v2.0 configuration.
     [Graham Leggett ]

  *) Fixed problem where responses without entity bodies would cause
     the directly following proxy keepalive request to fail.
     [Graham Leggett ]

mod_proxy changes for httpd 2.0.15

  *) Added support for downstream keepalives in mod_proxy.
     [Graham Leggett ]

  *) Changed mod_proxy ap_proxy_http_handler() to support APR properly.
     [Graham Leggett ]

  *) Fix problem where incoming response headers were not being returned
     to the client in mod_proxy.
     [Graham Leggett ]

  *) Added X-Forwarded-For, X-Forwarded-Host and X-Forwarded-Server to
     reverse proxied request headers in mod_proxy.
     [Graham Leggett ]

  *) replace INADDR_NONE with APR_INADDR_NONE [Ian Holsman ]

  *) Fix problem with proxy configuration where globally set
     configuration options were overridden inside virtual hosts.
     [Graham Leggett ]

  *) Fix ProxyReceiveBufferSize where default value was left
     uninitialised.
     [Graham Leggett ]

  *) Some small changes:
     - Ensured hop-by-hop headers were stripped as per
       RFC2616 13.5.1.
     - Upgraded version code to HTTP/1.1.
     - Added Connection: close until Keepalives come.
     - Some cosmetic fixes and commenting.
     [Graham Leggett ]

mod_proxy changes for httpd 2.0.14

  *) removed ProxyNoCache and ProxyCacheForceCompletion config directives,
     since we no longer directly cache from this module
     [Chuck Murcko ]

  *) removed cache
     [Chuck Murcko ]

  *) initial rerebuild for 2.0
     [Chuck Murcko ]

 * The idea behind the find_best_byrequests scheduler is the following:
 *
 * lbfactor is "how much we expect this worker to work", or "the worker's
 * normalized work quota".
 *
 * lbstatus is "how urgent this worker has to work to fulfill its quota
 * of work".
 *
 * We distribute each worker's work quota to the worker, and then look
 * which of them needs to work most urgently (biggest lbstatus).  This
 * worker is then selected for work, and its lbstatus reduced by the
 * total work quota we distributed to all workers.  Thus the sum of all
 * lbstatus does not change.(*)
 *
 * If some workers are disabled, the others will
 * still be scheduled correctly.
 *
 * If a balancer is configured as follows:
 *
 * worker     a    b    c    d
 * lbfactor  25   25   25   25
 *
 * And b gets disabled, the following schedule is produced:
 *
 *    a c d a c d a c d ...
 *
 * Note that the above lbfactor setting is the *exact* same as:
 *
 * worker     a    b    c    d
 * lbfactor   1    1    1    1
 *
 * Asymmetric configurations work as one would expect. For
 * example:
 *
 * worker     a    b    c    d
 * lbfactor   1    1    1    2
 *
 * would have a, b and c all handling about the same
 * amount of load with d handling twice what a or b
 * or c handles individually. So we could see:
 *
 *   b a d c d a c d b d ...

/*
 * This module is used to load Apache modules at runtime. This means that the
 * server functionality can be extended without recompiling and even without
 * taking the server down at all. Only a HUP or AP_SIG_GRACEFUL signal
 * needs to be sent to the server to reload the dynamically loaded modules.
 *
 * To use, you'll first need to build your module as a shared library, then
 * update your configuration (httpd.conf) to get the Apache core to load the
 * module at start-up.
 *
 * The easiest way to build a module as a shared library is to use the
 * `SharedModule' command in the Configuration file, instead of `AddModule'.
 * You should also change the file extension from `.o' to `.so'. So, for
 * example, to build the status module as a shared library edit Configuration
 * and change
 *   AddModule    modules/standard/mod_status.o
 * to
 *   SharedModule modules/standard/mod_status.so
 *
 * Run Configure and make. Now Apache's httpd binary will _not_ include
 * mod_status. Instead a shared object called mod_status.so will be build, in
 * the modules/standard directory. You can build most of the modules as shared
 * libraries like this.
 *
 * To use the shared module, move the .so file(s) into an appropriate
 * directory. You might like to create a directory called "modules" under you
 * server root for this (e.g. /usr/local/httpd/modules).
 *
 * Then edit your conf/httpd.conf file, and add LoadModule lines. For
 * example
 *   LoadModule  status_module   modules/mod_status.so
 *
 * The first argument is the module's structure name (look at the end of the
 * module source to find this). The second option is the path to the module
 * file, relative to the server root.  Put these directives right at the top
 * of your httpd.conf file.
 *
 * Now you can start Apache. A message will be logged at "debug" level to your
 * error_log to confirm that the module(s) are loaded (use "LogLevel debug"
 * directive to get these log messages).
 *
 * If you edit the LoadModule directives while the server is live you can get
 * Apache to re-load the modules by sending it a HUP or AP_SIG_GRACEFUL
 * signal as normal.  You can use this to dynamically change the capability
 * of your server without bringing it down.
 *
 * Because currently there is only limited builtin support in the Configure
 * script for creating the shared library files (`.so'), please consult your
 * vendors cc(1), ld(1) and dlopen(3) manpages to find out the appropriate
 * compiler and linker flags and insert them manually into the Configuration
 * file under CFLAGS_SHLIB, LDFLAGS_SHLIB and LDFLAGS_SHLIB_EXPORT.
 *
 * If you still have problems figuring out the flags both try the paper
 *     http://developer.netscape.com/library/documentation/enterprise
 *                                          /unix/svrplug.htm#1013807

/*
 * Modified by djm@va.pubnix.com:
 * If no TransferLog is given explicitly, decline to log.
 *
 * This is module implements the TransferLog directive (same as the
 * common log module), and additional directives, LogFormat and CustomLog.
 *
 *
 * Syntax:
 *
 *    TransferLog fn      Logs transfers to fn in standard log format, unless
 *                        a custom format is set with LogFormat
 *    LogFormat format    Set a log format from TransferLog files
 *    CustomLog fn format
 *                        Log to file fn with format given by the format
 *                        argument
 *
 * There can be any number of TransferLog and CustomLog
 * commands. Each request will be logged to _ALL_ the
 * named files, in the appropriate format.
 *
 * If no TransferLog or CustomLog directive appears in a VirtualHost,
 * the request will be logged to the log file(s) defined outside
 * the virtual host section. If a TransferLog or CustomLog directive
 * appears in the VirtualHost section, the log files defined outside
 * the VirtualHost will _not_ be used. This makes this module compatible
 * with the CLF and config log modules, where the use of TransferLog
 * inside the VirtualHost section overrides its use outside.
 *
 * Examples:
 *
 *    TransferLog    logs/access_log
 *    
 *    LogFormat      "... custom format ..."
 *    TransferLog    log/virtual_only
 *    CustomLog      log/virtual_useragents "%t %{user-agent}i"
 *    
 *
 * This will log using CLF to access_log any requests handled by the
 * main server, while any requests to the virtual host will be logged
 * with the "... custom format..." to virtual_only _AND_ using
 * the custom user-agent log to virtual_useragents.
 *
 * Note that the NCSA referer and user-agent logs are easily added with
 * CustomLog:
 *   CustomLog   logs/referer  "%{referer}i -> %U"
 *   CustomLog   logs/agent    "%{user-agent}i"
 *
 * RefererIgnore functionality can be obtained with conditional
 * logging (SetEnvIf and CustomLog ... env=!VAR).
 *
 * But using this method allows much easier modification of the
 * log format, e.g. to log hosts along with UA:
 *   CustomLog   logs/referer "%{referer}i %U %h"
 *
 * The argument to LogFormat and CustomLog is a string, which can include
 * literal characters copied into the log files, and '%' directives as
 * follows:
 *
 * %...B:  bytes sent, excluding HTTP headers.
 * %...b:  bytes sent, excluding HTTP headers in CLF format, i.e. a '-'
 *         when no bytes where sent (rather than a '0'.
 * %...{FOOBAR}C:  The contents of the HTTP cookie FOOBAR
 * %...{FOOBAR}e:  The contents of the environment variable FOOBAR
 * %...f:  filename
 * %...h:  remote host
 * %...a:  remote IP-address
 * %...A:  local IP-address
 * %...{Foobar}i:  The contents of Foobar: header line(s) in the request
 *                 sent to the client.
 * %...k:  number of keepalive requests served over this connection
 * %...l:  remote logname (from identd, if supplied)
 * %...{Foobar}n:  The contents of note "Foobar" from another module.
 * %...{Foobar}o:  The contents of Foobar: header line(s) in the reply.
 * %...p:  the canonical port for the server
 * %...{format}p: the canonical port for the server, or the actual local
 *                or remote port
 * %...P:  the process ID of the child that serviced the request.
 * %...{format}P: the process ID or thread ID of the child/thread that
 *                serviced the request
 * %...r:  first line of request
 * %...s:  status.  For requests that got internally redirected, this
 *         is status of the *original* request --- %...>s for the last.
 * %...t:  time, in common log format time format
 * %...{format}t:  The time, in the form given by format, which should
 *                 be in strftime(3) format.
 * %...T:  the time taken to serve the request, in seconds.
 * %...{s}T:  the time taken to serve the request, in seconds, same as %T.
 * %...{us}T:  the time taken to serve the request, in micro seconds, same as %D.
 * %...{ms}T:  the time taken to serve the request, in milliseconds.
 * %...D:  the time taken to serve the request, in micro seconds.
 * %...u:  remote user (from auth; may be bogus if return status (%s) is 401)
 * %...U:  the URL path requested.
 * %...v:  the configured name of the server (i.e. which virtual host?)
 * %...V:  the server name according to the UseCanonicalName setting
 * %...m:  the request method
 * %...H:  the request protocol
 * %...q:  the query string prepended by "?", or empty if no query string
 * %...X:  Status of the connection.
 *         'X' = connection aborted before the response completed.
 *         '+' = connection may be kept alive after the response is sent.
 *         '-' = connection will be closed after the response is sent.
 *         (This directive was %...c in late versions of Apache 1.3, but
 *          this conflicted with the historical ssl %...{var}c syntax.)
 * %...L:  Log-Id of the Request (or '-' if none)
 * %...{c}L:  Log-Id of the Connection (or '-' if none)
 *
 * The '...' can be nothing at all (e.g. "%h %u %r %s %b"), or it can
 * indicate conditions for inclusion of the item (which will cause it
 * to be replaced with '-' if the condition is not met).  Note that
 * there is no escaping performed on the strings from %r, %...i and
 * %...o; some with long memories may remember that I thought this was
 * a bad idea, once upon a time, and I'm still not comfortable with
 * it, but it is difficult to see how to "do the right thing" with all
 * of '%..i', unless we URL-escape everything and break with CLF.
 *
 * The forms of condition are a list of HTTP status codes, which may
 * or may not be preceded by '!'.  Thus, '%400,501{User-agent}i' logs
 * User-agent: on 400 errors and 501 errors (Bad Request, Not
 * Implemented) only; '%!200,304,302{Referer}i' logs Referer: on all
 * requests which did *not* return some sort of normal status.
 *
 * The default LogFormat reproduces CLF; see below.
 *
 * The way this is supposed to work with virtual hosts is as follows:
 * a virtual host can have its own LogFormat, or its own TransferLog.
 * If it doesn't have its own LogFormat, it inherits from the main
 * server.  If it doesn't have its own TransferLog, it writes to the
 * same descriptor (meaning the same process for "| ...").

 *
 * The structure is treated as mostly immutable after a single config
 * parse has completed; the post_config hook (ssl_init_Module) flips
 * the bFixed flag to true and subsequent invocations of the config
 * callbacks hence do nothing.
 *
 * This odd lifetime strategy is used so that encrypted private keys
 * can be decrypted once at startup and continue to be used across
 * subsequent server reloads where the interactive password prompt is
 * not possible.

 * It is really an ABI nightmare waiting to happen since DSOs are
 * reloaded across restarts, and nothing prevents the struct type
 * changing across such reloads, yet the cached structure will be
 * assumed to match regardless.
 *
 * This should really be fixed using a smaller structure which only
 * stores that which is absolutely necessary (the private keys, maybe
 * the random seed), and have that structure be strictly ABI-versioned

 This Apache module provides strong cryptography for the Apache 2 webserver
 via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS
 v1) protocols by the help of the SSL/TLS implementation library OpenSSL which
 is based on SSLeay from Eric A. Young and Tim J. Hudson. 

 The mod_ssl package was created in April 1998 by Ralf S. Engelschall 
 and was originally derived from software developed by Ben Laurie for 
 use in the Apache-SSL HTTP server project.  The mod_ssl implementation 
 for Apache 1.3 continues to be supported by the modssl project 
 .

SOURCES

 See the top-level LAYOUT file for file descriptions.

 The source files are written in clean ANSI C and pass the ``gcc -O -g
 -ggdb3 -Wall -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
 -Wmissing-declarations -Wnested-externs -Winline'' compiler test
 (assuming `gcc' is GCC 2.95.2 or newer) without any complains. When
 you make changes or additions make sure the source still passes this
 compiler test.

FUNCTIONS
  
 Inside the source code you will be confronted with the following types of
 functions which can be identified by their prefixes:

   ap_xxxx() ............... Apache API function
   ssl_xxxx() .............. mod_ssl function
   SSL_xxxx() .............. OpenSSL function (SSL library)
   OpenSSL_xxxx() .......... OpenSSL function (SSL library)
   X509_xxxx() ............. OpenSSL function (Crypto library)
   PEM_xxxx() .............. OpenSSL function (Crypto library)
   EVP_xxxx() .............. OpenSSL function (Crypto library)
   RSA_xxxx() .............. OpenSSL function (Crypto library)

DATA STRUCTURES

 Inside the source code you will be confronted with the following
 data structures:

   server_rec .............. Apache (Virtual) Server
   conn_rec ................ Apache Connection
   request_rec ............. Apache Request
   SSLModConfig ............ mod_ssl (Global)  Module Configuration
   SSLSrvConfig ............ mod_ssl (Virtual) Server Configuration
   SSLDirConfig ............ mod_ssl Directory Configuration
   SSLConnConfig ........... mod_ssl Connection Configuration
   SSLFilterRec ............ mod_ssl Filter Context
   SSL_CTX ................. OpenSSL Context
   SSL_METHOD .............. OpenSSL Protocol Method
   SSL_CIPHER .............. OpenSSL Cipher
   SSL_SESSION ............. OpenSSL Session
   SSL ..................... OpenSSL Connection
   BIO ..................... OpenSSL Connection Buffer

 For an overview how these are related and chained together have a look at the
 page in README.dsov.{fig,ps}. It contains overview diagrams for those data
 structures. It's designed for DIN A4 paper size, but you can easily generate
 a smaller version inside XFig by specifying a magnification on the Export
 panel.

INCOMPATIBILITIES

 The following intentional incompatibilities exist between mod_ssl 2.x
 from Apache 1.3 and this mod_ssl version for Apache 2:

 o The complete EAPI-based SSL_VENDOR stuff was removed.
 o The complete EAPI-based SSL_COMPAT stuff was removed.
 o The  variable MOD_SSL is no longer provided automatically 

MAJOR CHANGES 

 For a complete history of changes for Apache 2 mod_ssl, see the 
 CHANGES file in the top-level directory.  The following 
 is a condensed summary of the major changes were made between 
 mod_ssl 2.x from Apache 1.3 and this mod_ssl version for Apache 2:

 o The DBM based session cache is now based on APR's DBM API only.
 o The shared memory based session cache is now based on APR's APIs.
 o SSL I/O is now implemented in terms of filters rather than BUFF
 o Eliminated ap_global_ctx. Storing Persistent information in 
   process_rec->pool->user_data. The ssl_pphrase_Handle_CB() and 
   ssl_config_global_* () functions have an extra parameter now - 
   "server_rec *" -  which is used to retrieve the SSLModConfigRec.
 o Properly support restarts, allowing mod_ssl to be added to a server
   that is already running and to change server certs/keys on restart
 o Various performance enhancements
 o proxy support is no longer an "extension", much of the mod_ssl core
   was re-written (ssl_engine_{init,kernel,config}.c) to be generic so
   it could be re-used in proxy mode.
   - the optional function ssl_proxy_enable is provide for mod_proxy
     to enable proxy support
   - proxy support now requires 'SSLProxyEngine on' to be configured
   - proxy now supports SSLProxyCARevocation{Path,File} in addition to
     the original SSLProxy* directives
 o per-directory SSLCACertificate{File,Path} is now thread-safe but
   requires SSL_set_cert_store patch to OpenSSL
 o the ssl_engine_{ds,ext}.c source files are obsolete and no longer
   exist

/* This file is designed to be the bridge between OpenSSL and httpd.
 * However, we really don't expect anyone (let alone ourselves) to
 * remember what is in this file.  So, first, a quick overview.
 *
 * In this file, you will find:
 * - ssl_io_filter_input    (Apache input filter)
 * - ssl_io_filter_output   (Apache output filter)
 *
 * - bio_filter_in_*        (OpenSSL input filter)
 * - bio_filter_out_*       (OpenSSL output filter)
 *
 * The input chain is roughly:
 *
 * ssl_io_filter_input->ssl_io_input_read->SSL_read->...
 * ...->bio_filter_in_read->ap_get_brigade/next-httpd-filter
 *
 * In mortal terminology, we do the following:
 * - Receive a request for data to the SSL input filter
 * - Call a helper function once we know we should perform a read
 * - Call OpenSSL's SSL_read()
 * - SSL_read() will then call bio_filter_in_read
 * - bio_filter_in_read will then try to fetch data from the next httpd filter
 * - bio_filter_in_read will flatten that data and return it to SSL_read
 * - SSL_read will then decrypt the data
 * - ssl_io_input_read will then receive decrypted data as a char* and
 *   ensure that there were no read errors
 * - The char* is placed in a brigade and returned
 *
 * Since connection-level input filters in httpd need to be able to
 * handle AP_MODE_GETLINE calls (namely identifying LF-terminated strings),
 * ssl_io_input_getline which will handle this special case.
 *
 * Due to AP_MODE_GETLINE and AP_MODE_SPECULATIVE, we may sometimes have
 * 'leftover' decoded data which must be setaside for the next read.  That
 * is currently handled by the char_buffer_{read|write} functions.  So,
 * ssl_io_input_read may be able to fulfill reads without invoking
 * SSL_read().
 *
 * Note that the filter context of ssl_io_filter_input and bio_filter_in_*
 * are shared as bio_filter_in_ctx_t.
 *
 * Note that the filter is by choice limited to reading at most
 * AP_IOBUFSIZE (8192 bytes) per call.
 *
 */

/* this custom BIO allows us to hook SSL_write directly into
 * an apr_bucket_brigade and use transient buckets with the SSL
 * malloc-ed buffer, rather than copying into a mem BIO.
 * also allows us to pass the brigade as data is being written
 * rather than buffering up the entire response in the mem BIO.
 *
 * when SSL needs to flush (e.g. SSL_accept()), it will call BIO_flush()
 * which will trigger a call to bio_filter_out_ctrl() -> bio_filter_out_flush().
 * so we only need to flush the output ourselves if we receive an
 * EOS or FLUSH bucket. this was not possible with the mem BIO where we
 * had to flush all over the place not really knowing when it was required
 * to do so.

Broadcasts the current Apache Connection status over multicast.

Example Configuration:
  HeartbeatAddress 239.0.0.1:27999

Dependencies:
  mod_status must be either a static module, or if a dynamic module, it must be 
  loaded before mod_heartbeat.


Consuming:
  Every 1 second, this module generates a single multicast UDP packet,
  containing the number of busy and idle workers.
  
  The packet is a simple ASCII format, similar to GET query parameters in UDP.
  
  An Example packet:
    v=1&ready=75&busy=0

  Consumers should handle new variables besides busy and ready, separated by '&'
  being added in the future.
  
Misc:
  The interval of 1 seconds is controlled by the HEARTBEAT_INTERVAL
  compile time define.  This is not currently tunable at run time. To make this
  module send the status packet more often, you must add to the CFLAGS used to
  compile the module to include:
    -DHEARTBEAT_INTERVAL=3
  Would cause the broadcasts to be sent every 3 seconds.

Collects the Apache Connection status data over multicast.

Example Configuration:
  # First parameter is the interface to listen on
  HeartbeatListen 239.0.0.1:27999
  # Absolute path, or relative path to ServerRoot
  HeartbeatStorage logs/hb.dat

Dependencies:
  Due to a bug in APR's apr_socket_recvfrom, version 1.2.12 or newer must be
  used:
    

Consuming:
  This module atomically writes to the configured path, a list of servers, 
  along with metadata about them.
  
  Included data about each server:
    - IP Address
    - Busy Slots
    - Open Slots
    - Last Seen

  Every 5 seconds, this file will be updated with the current status of the 
  cluster.

dnl find_apu.m4 : locate the APR-util (APU) include files and libraries
dnl
dnl This macro file can be used by applications to find and use the APU
dnl library. It provides a standardized mechanism for using APU. It supports
dnl embedding APU into the application source, or locating an installed
dnl copy of APU.
dnl
dnl APR_FIND_APU(srcdir, builddir, implicit-install-check, acceptable-majors,
dnl              detailed-check)
dnl
dnl   where srcdir is the location of the bundled APU source directory, or
dnl   empty if source is not bundled.
dnl
dnl   where builddir is the location where the bundled APU will be built,
dnl   or empty if the build will occur in the srcdir.
dnl
dnl   where implicit-install-check set to 1 indicates if there is no
dnl   --with-apr-util option specified, we will look for installed copies.
dnl
dnl   where acceptable-majors is a space separated list of acceptable major
dnl   version numbers. Often only a single major version will be acceptable.
dnl   If multiple versions are specified, and --with-apr-util=PREFIX or the
dnl   implicit installed search are used, then the first (leftmost) version
dnl   in the list that is found will be used.  Currently defaults to [0 1].
dnl
dnl   where detailed-check is an M4 macro which sets the apu_acceptable to
dnl   either "yes" or "no". The macro will be invoked for each installed
dnl   copy of APU found, with the apu_config variable set appropriately.
dnl   Only installed copies of APU which are considered acceptable by
dnl   this macro will be considered found. If no installed copies are
dnl   considered acceptable by this macro, apu_found will be set to either
dnl   either "no" or "reconfig".
dnl
dnl Sets the following variables on exit:
dnl
dnl   apu_found : "yes", "no", "reconfig"
dnl
dnl   apu_config : If the apu-config tool exists, this refers to it.  If
dnl                apu_found is "reconfig", then the bundled directory
dnl                should be reconfigured *before* using apu_config.
dnl
dnl Note: this macro file assumes that apr-config has been installed; it
dnl       is normally considered a required part of an APR installation.
dnl
dnl Note: At this time, we cannot find *both* a source dir and a build dir.
dnl       If both are available, the build directory should be passed to
dnl       the --with-apr-util switch.
dnl
dnl Note: the installation layout is presumed to follow the standard
dnl       PREFIX/lib and PREFIX/include pattern. If the APU config file
dnl       is available (and can be found), then non-standard layouts are
dnl       possible, since it will be described in the config file.
dnl
dnl If a bundled source directory is available and needs to be (re)configured,
dnl then apu_found is set to "reconfig". The caller should reconfigure the
dnl (passed-in) source directory, placing the result in the build directory,
dnl as appropriate.
dnl
dnl If apu_found is "yes" or "reconfig", then the caller should use the
dnl value of apu_config to fetch any necessary build/link information.

## Global variables. ##
## ----------------- ##

# Except for the global variables explicitly listed below, the following
# functions in the '^func_' namespace, and the '^require_' namespace
# variables initialised in the 'Resource management' section, sourcing
# this file will not pollute your global namespace with anything
# else. There's no portable way to scope variables in Bourne shell
# though, so actually running these functions will sometimes place
# results into a variable named after the function, and often use
# temporary variables in the '^_G_' namespace. If you are careful to
# avoid using those namespaces casually in your sourcing script, things
# should continue to work as you expect. And, of course, you can freely
# overwrite any of the functions or variables defined here before
# calling anything to customize them.

# Allow overriding, eg assuming that you follow the convention of
# putting '$debug_cmd' at the start of all your functions, you can get
# bash to show function call trace with:
#
#    debug_cmd='eval echo "${FUNCNAME[0]} $*" >&2' bash your-script-name

# By convention, finish your script with:

# the point of failure.

## ------ ##
## Usage. ##
## ------ ##

# This file is a library for parsing options in your shell scripts along
# with assorted other useful supporting features that you can make use
# of too.
#
# For the simplest scripts you might need only:
#
#   #!/bin/sh
#   . relative/path/to/funclib.sh
#   . relative/path/to/options-parser
#   scriptversion=1.0
#   func_options ${1+"$@"}
#   eval set dummy "$func_options_result"; shift
#   ...rest of your script...
#
# In order for the '--version' option to work, you will need to have a
# suitably formatted comment like the one at the top of this file
# starting with '# Written by ' and ending with '# warranty; '.
#
# For '-h' and '--help' to work, you will also need a one line
# description of your script's purpose in a comment directly above the
# '# Written by ' line, like the one at the top of this file.
#
# The default options also support '--debug', which will turn on shell
# execution tracing (see the comment above debug_cmd below for another
# use), and '--verbose' and the func_verbose function to allow your script
# to display verbose messages only when your user has specified
# '--verbose'.
#
# After sourcing this file, you can plug processing for additional
# options by amending the variables from the 'Configuration' section
# below, and following the instructions in the 'Option parsing'
# section further down.

## -------------- ##
## Configuration. ##
## -------------- ##

# You should override these variables in your script after sourcing this
# file so that they reflect the customisations you have added to the
# option parser.

# The usage line for option parsing errors and the start of '-h' and
# '--help' output messages. You can embed shell variables for delayed
# expansion at the time the message is displayed, but you will need to
# quote other shell meta-characters carefully to prevent them being
# expanded when the contents are evaled.
usage='$progpath [OPTION]...'

# Short help message in response to '-h' and '--help'.  Add to this or
# override it after sourcing this library to reflect the full set of
# options your script accepts.
usage_message="\
       --debug        enable verbose shell tracing
   -W, --warnings=CATEGORY
                      report the warnings falling in CATEGORY [all]
   -v, --verbose      verbosely report processing
       --version      print version information and exit
   -h, --help         print short or long help message and exit
"

# Additional text appended to 'usage_message' in response to '--help'.
long_help_message="
Warning categories include:
       'all'          show all warnings
       'none'         turn off all the warnings
       'error'        warnings are treated as fatal errors"

treated as uninstalled libtool libraries, other files are standard or library
object files.

If the OUTPUT-FILE ends in '.la', then a libtool library is created,
only library objects ('.lo' files) may be specified, and '-rpath' is
required, except when creating a convenience library.

If OUTPUT-FILE ends in '.a' or '.lib', then a standard library is created
using 'ar' and 'ranlib', or on Windows using 'lib'.

If OUTPUT-FILE ends in '.lo' or '.$objext', then a reloadable object file
is created, otherwise an executable program is created."

   - Space and tab are interpreted as delimiters. They are not treated as
     delimiters if they are surrounded by double quotes: "...".
   - Unescaped double quotes are removed from the input. Their only effect is
     that within double quotes, space and tab are treated like normal
     characters.
   - Backslashes not followed by double quotes are not special.
   - But 2*n+1 backslashes followed by a double quote become
     n backslashes followed by a double quote (n >= 0):

# the user asked for that or because the platform doesn't support

# support having both static and shared libraries enabled at the same
# time on that platform, so we default to a shared-only configuration.
# If a disable-shared tag is given, we'll fallback to a static-only

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.

# You can get the latest version of this script from:
# https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub

# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support.  The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.

# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.

dnl find_apr.m4 : locate the APR include files and libraries
dnl
dnl This macro file can be used by applications to find and use the APR
dnl library. It provides a standardized mechanism for using APR. It supports
dnl embedding APR into the application source, or locating an installed
dnl copy of APR.
dnl
dnl APR_FIND_APR(srcdir, builddir, implicit-install-check, acceptable-majors,
dnl              detailed-check)
dnl
dnl   where srcdir is the location of the bundled APR source directory, or
dnl   empty if source is not bundled.
dnl
dnl   where builddir is the location where the bundled APR will will be built,
dnl   or empty if the build will occur in the srcdir.
dnl
dnl   where implicit-install-check set to 1 indicates if there is no
dnl   --with-apr option specified, we will look for installed copies.
dnl
dnl   where acceptable-majors is a space separated list of acceptable major
dnl   version numbers. Often only a single major version will be acceptable.
dnl   If multiple versions are specified, and --with-apr=PREFIX or the
dnl   implicit installed search are used, then the first (leftmost) version
dnl   in the list that is found will be used.  Currently defaults to [0 1].
dnl
dnl   where detailed-check is an M4 macro which sets the apr_acceptable to
dnl   either "yes" or "no". The macro will be invoked for each installed
dnl   copy of APR found, with the apr_config variable set appropriately.
dnl   Only installed copies of APR which are considered acceptable by
dnl   this macro will be considered found. If no installed copies are
dnl   considered acceptable by this macro, apr_found will be set to either
dnl   either "no" or "reconfig".
dnl
dnl Sets the following variables on exit:
dnl
dnl   apr_found : "yes", "no", "reconfig"
dnl
dnl   apr_config : If the apr-config tool exists, this refers to it. If
dnl                apr_found is "reconfig", then the bundled directory
dnl                should be reconfigured *before* using apr_config.
dnl
dnl Note: this macro file assumes that apr-config has been installed; it
dnl       is normally considered a required part of an APR installation.
dnl
dnl If a bundled source directory is available and needs to be (re)configured,
dnl then apr_found is set to "reconfig". The caller should reconfigure the
dnl (passed-in) source directory, placing the result in the build directory,
dnl as appropriate.
dnl
dnl If apr_found is "yes" or "reconfig", then the caller should use the
dnl value of apr_config to fetch any necessary build/link information.

out of a source tree for httpd.

To build a package, make sure you are in the root of the source tree,
and run:

build/pkg/buildpkg.sh

A Solaris package called httpd---local.gz will be
created in the root of the source tree.

By default, the script will attempt to find a system installed version of
APR and APR-util v1. You may override the location of apr or apr-util like so:

build/pkg/buildpkg.sh --with-apr=some/other/path --with-apr-util=some/other/path

out of a source tree for ASF project

REQUIREMENTS:
  Fileset                      Level  State  Type  Description (Uninstaller)
  ----------------------------------------------------------------------------
  bos.adt.insttools          5.3.7.2    C     F    Tool to Create installp
                                                   Packages
  Fileset                      Level  State  Type  Description (Uninstaller)
  ----------------------------------------------------------------------------
  rpm.rte                   3.0.5.41    C     F    RPM Package Manager

Additional:
Preferred: download zlib sources and copy zlib.h and zconf.h to /opt/include
and, if configure cannot find them directly, add symbolic links from /usr/include to /opt/include

To build a package, make sure you are in the root of the source tree,
and run:

build/aix/buildaix.ksh

An AIX fileset named $PKG.$NAME.$ARCH.$VERSION.I will be
created in the build/aix directory. the .template file created is also there.

KNOWN issues:
on AIX libtool is known to have issues with the install command.
Some of these issues have been resolved by extracting the apr/apu utilities
from the projects (i.e. NOT using the embedded version)
In case of problems I recommend that you install the GNU 'install' program (part of coreutils)
If make DESTDIR=$TEMPDIR install command continues to fail, try 'make install' and then run
the buildaix.ksh command again

TODO
Add Copyright display/banner
Add Apache LICENSE to fileset and require acceptance
Add special instructions for TCB - to ignore /etc/* /var/httpd/htdocs/*
Add _config_i scripts to setup autostart
Add _pre_i scripts to verify pre-requisites, required users/groups, etc.

# This layout is intended to put customizeable data in /etc and /var

/* This apr_table_t is (almost) identical to the previous one. The only difference
 * is the fact that it maps every EBCDIC *except 0x0A* to its ASCII
 * equivalent. The reason for this apr_table_t is simple: Throughout the
 * server, protocol strings are used in the form
 *  "Content-Type: text/plain\015\012". Now all the characters in the string
 * are stored as EBCDIC, only the semantics of \012 is completely
 * different from LF (look it up in the apr_table_t above). \015 happens to be
 * mapped to \015 anyway, so there's no special case for it.
 *
 * In THIS table, EBCDIC-\012 is mapped to ASCII-\012.
 * This apr_table_t is therefore used wherever an EBCDIC to ASCII conversion is
 * needed in the server.

ab
	ABuse your server with this benchmarker. Rudimentary
	command line testing tool.

apachectl
	Apache run-time Control script. To facilitate the
	administrator and/or your rc.d scripts to control the 
	functioning of the Apache httpd daemon.

apxs
	APache eXtenSion tool. Eases building and installing
	DSO style modules.

dbmmanage
	Create and update user authentication files in the faster
	DBM format used by mod_auth_db.

htcacheclean
    Keep the size of mod_cache_disk store within a certain limit.

htdigest
	Create and update user authentication files used in
	DIGEST authentification. See mod_auth_digest.

htpasswd 
	Create and update user authentication files used in
	BASIC authentification. I.e. the htpasswd files.
	See mod_auth.

httpd.8
	General apache man page.

log_server_status
	This script is designed to be run at a frequent interval by something
	like cron.  It connects to the server and downloads the status
	information.  It reformats the information to a single line and logs
	it to a file. 

logresolve
	resolve hostnames for IP-adresses in Apache logfiles

phf_abuse_log.cgi
	This script can be used to detect people trying to abuse an ancient
	and long plugged security hole which existed in a CGI script distributed
	with Apache 1.0.3 and earlier versions.

rotatelogs
	rotate Apache logs without having to kill the server.

split-logfile
	This script will take a combined virtual hosts access
	log file and break its contents into separate files.

suexec
	Switch User For Exec. Used internally by apache, 
        see  the  document  `Apache  suEXEC  Support'
	under http://www.apache.org/docs/suexec.html .

SHA1
	This directory includes some utilities to allow Apache 1.3.6 to 
	recognize passwords in SHA1 format, as used by Netscape web 
	servers. It is not installed by default.

# v 1.2 by robh imdb.com
# 
# usage: logresolve.pl outfile
#
# input = Apache/NCSA/.. logfile with IP numbers at start of lines
# output = same logfile with IP addresses resolved to hostnames where
#  name lookups succeeded.
#
# this differs from the C based 'logresolve' in that this script
# spawns a number ($CHILDREN) of subprocesses to resolve addresses
# concurrently and sets a short timeout ($TIMEOUT) for each lookup in
# order to keep things moving quickly.
#
# the parent process handles caching of IP->hostnames using a Perl hash
# it also avoids sending the same IP to multiple child processes to be
# resolved multiple times concurrently.
#
# Depending on the settings of $CHILDREN and $TIMEOUT you should see
# significant reductions in the overall time taken to resolve your
# logfiles. With $CHILDREN=40 and $TIMEOUT=5 I've seen 200,000 - 300,000
# logfile lines processed per hour compared to ~45,000 per hour
# with 'logresolve'.
#
# I haven't yet seen any noticeable reduction in the percentage of IPs
# that fail to get resolved. Your mileage will no doubt vary. 5s is long
# enough to wait IMO.
#
# Known to work with FreeBSD 2.2
# Known to have problems with Solaris
#
# 980417 - use 'sockaddr_un' for bind/connect to make the script work
#  with linux. Fix from Luuk de Boer

/*
 * logresolve 2.0
 *
 * Tom Rathborne - tomr uunet.ca - http://www.uunet.ca/~tomr/
 * UUNET Canada, April 16, 1995
 *
 * Rewritten by David Robinson. (drtr ast.cam.ac.uk)
 * Rewritten again, and ported to APR by Colm MacCarthaigh
 *
 * Usage: logresolve [-s filename] [-c] < access_log > new_log
 *
 * Arguments:
 *    -s filename     name of a file to record statistics
 *    -c              check the DNS for a matching A record for the host.
 *
 * Notes:             (For historical interest)
 *
 * To generate meaningful statistics from an HTTPD log file, it's good
 * to have the domain name of each machine that accessed your site, but
 * doing this on the fly can slow HTTPD down.
 *
 * Compiling NCSA HTTPD with the -DMINIMAL_DNS flag turns IP#->hostname
 * resolution off. Before running your stats program, just run your log
 * file through this program (logresolve) and all of your IP numbers will
 * be resolved into hostnames (where possible).
 *
 * logresolve takes an HTTPD access log (in the COMMON log file format,
 * or any other format that has the IP number/domain name as the first
 * field for that matter), and outputs the same file with all of the
 * domain names looked up. Where no domain name can be found, the IP
 * number is left in.
 *
 * To minimize impact on your nameserver, logresolve has its very own
 * internal hash-table cache. This means that each IP number will only
 * be looked up the first time it is found in the log file.
 *
 * The -c option causes logresolve to apply the same check as httpd
 * compiled with -DMAXIMUM_DNS; after finding the hostname from the IP
 * address, it looks up the IP addresses for the hostname and checks
 * that one of these matches the original address.

**  mod_%NAME%.c -- Apache sample %NAME% module
**  [Autogenerated via ``apxs -n %NAME% -g'']
**
**  To play with this sample module first compile it into a
**  DSO file and install it into Apache's modules directory 
**  by running:
**
**    $ apxs -c -i mod_%NAME%.c
**
**  Then activate it in Apache's %TARGET%.conf file for instance
**  for the URL /%NAME% in as follows:
**
**    #   %TARGET%.conf
**    LoadModule %NAME%_module modules/mod_%NAME%.so
**    
**    SetHandler %NAME%
**    
**
**  Then after restarting Apache via
**
**    $ apachectl restart
**
**  you immediately can request the URL /%NAME% and watch for the
**  output of this module. This can be achieved for instance via:
**
**    $ lynx -mime_header http://localhost/%NAME% 
**
**  The output should be similar to the following one:
**
**    HTTP/1.1 200 OK
**    Date: Tue, 31 Mar 1998 14:42:22 GMT
**    Server: Apache/1.3.4 (Unix)
**    Connection: close
**    Content-Type: text/html

/*
   ** HISTORY:
   **    - Originally written by Adam Twiss , March 1996
   **      with input from Mike Belshe  and
   **      Michael Campanella 
   **    - Enhanced by Dean Gaudet , November 1997
   **    - Cleaned up by Ralf S. Engelschall , March 1998
   **    - POST and verbosity by Kurt Sussman , August 1998
   **    - HTML table output added by David N. Welton , January 1999
   **    - Added Cookie, Arbitrary header and auth support. , April 1999
   ** Version 1.3d
   **    - Increased version number - as some of the socket/error handling has
   **      fundamentally changed - and will give fundamentally different results
   **      in situations where a server is dropping requests. Therefore you can
   **      no longer compare results of AB as easily. Hence the inc of the version.
   **      They should be closer to the truth though. Sander & , End 2000.
   **    - Fixed proxy functionality, added median/mean statistics, added gnuplot
   **      output option, added _experimental/rudimentary_ SSL support. Added
   **      confidence guestimators and warnings. Sander & , End 2000
   **    - Fixed serious int overflow issues which would cause realistic (longer
   **      than a few minutes) run's to have wrong (but believable) results. Added
   **      trapping of connection errors which influenced measurements.
   **      Contributed by Sander Temme, Early 2001
   ** Version 1.3e
   **    - Changed timeout behavior during write to work whilst the sockets
   **      are filling up and apr_write() does writes a few - but not all.
   **      This will potentially change results. , April 2001
   ** Version 2.0.36-dev
   **    Improvements to concurrent processing:
   **      - Enabled non-blocking connect()s.
   **      - Prevent blocking calls to apr_socket_recv() (thereby allowing AB to
   **        manage its entire set of socket descriptors).
   **      - Any error returned from apr_socket_recv() that is not EAGAIN or EOF
   **        is now treated as fatal.
   **      Contributed by Aaron Bannert, April 24, 2002
   **
   ** Version 2.0.36-2
   **     Internalized the version string - this string is part
   **     of the Agent: header and the result output.
   **
   ** Version 2.0.37-dev
   **     Adopted SSL code by Madhu Mathihalli 
   **     [PATCH] ab with SSL support  Posted Wed, 15 Aug 2001 20:55:06 GMT
   **     Introduces four 'if (int == value)' tests per non-ssl request.
   **
   ** Version 2.0.40-dev
   **     Switched to the new abstract pollset API, allowing ab to
   **     take advantage of future apr_pollset_t scalability improvements.
   **     Contributed by Brian Pane, August 31, 2002
   **
   ** Version 2.3
   **     SIGINT now triggers output_results().
   **     Contributed by colm, March 30, 2006

/* Note: this version string should start with \d+[\d\.]* and be a valid

 * It should reflect the version of AB - and not that of the apache server
 * it happens to accompany. And it should be updated or changed whenever
 * the results are no longer fundamentally comparable to the results of
 * a previous version of ab. Either due to a change in the logic of
 * ab - or to due to a change in the distribution it is compiled with

/*
 * BUGS:
 *
 * - uses strcpy/etc.
 * - has various other poor buffer attacks related to the lazy parsing of

 * - doesn't implement much of HTTP/1.x, only accepts certain forms of
 *   responses
 * - (performance problem) heavy use of strstr shows up top in profile
 *   only an issue for loopback usage

 * wintty : a Apache/WinNT support utility for monitoring and

 *          stdin/stdout, even as running within the service context.
 *
 * Originally contributed by William Rowe 
 *
 * Note: this implementation is _very_ experimental, and error handling
 * is far from complete.  Using it as a cgi or pipe process allows the
 * programmer to discover if facilities such as reliable piped logs
 * are working as expected, or answer operator prompts that would
 * otherwise be discarded by the service process.
 *
 * Also note the isservice detection semantics, which far exceed any
 * mechanism we have discovered thus far.

recognize passwords in SHA1 format, as used by Netscape web servers.  

From Netscape's admin interface, export the password database to an 
ldif file and then use convert.pl in this distribution to generate 
apache style password files.  

Note: SHA1 support is useful for migration purposes, but is less
      secure than Apache's password format, since Apache's (MD5)
      password format uses a random eight character salt to generate
      one of many possible hashes for the same password.  Netscape
      uses plain SHA1 without a salt, so the same password
      will always generate the same hash, making it easier
      to break since the search space is smaller.

This code was contributed by Clinton Wong .

 Multi Language Custom Error Documents
 -------------------------------------

 The 'error' directory contains HTTP error messages in multiple languages.
 If the preferred language of a client is available it is selected
 automatically via the MultiViews feature. This feature is enabled
 by default via the Options, Language and ErrorDocument directives.

 You may configure the design and markup of the documents by modifying
 the HTML files in the directory 'error/include'.

# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See  for detailed information.
# In particular, see 
# 
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 
# will be interpreted as '/logs/access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "@@ServerRoot@@"

#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:@rel_runtimedir@

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the 
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.

# 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a

# All of these directives may appear inside  containers,
# in which case these default settings will be overridden for the
# virtual host being defined.

# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. admin@your-domain.com
#
ServerAdmin you@example.com

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.

    # Redirect: Allows you to tell clients about documents that used to

    # Example:
    # Redirect permanent /foo http://www.example.com/bar

    #
    # Alias: Maps web paths into filesystem paths and is used to
    # access content that does not live under the DocumentRoot.
    # Example:
    # Alias /webpath /full/filesystem/path
    #
    # If you include a trailing / on /webpath then the server will

    #
    # AddHandler allows you to map certain file extensions to "handlers":

# This is the Apache server configuration file providing SSL support.
# It contains the configuration directives to instruct the server how to
# serve pages over an https connection. For detailed information about these 
# directives see 
# 
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Required modules: mod_log_config, mod_setenvif, mod_ssl,
#          socache_shmcb_module (for default value of SSLSessionCache)

#
# Pseudo Random Number Generator (PRNG):
# Configure one or more sources to seed the PRNG of the SSL library.
# The seed data should be of good random quality.
# WARNING! On some platforms /dev/random blocks if not enough entropy
# is available. This means you then cannot use the /dev/random device
# because it would lead to very long connection times (as long as
# it requires to make more entropy available). But usually those
# platforms additionally provide a /dev/urandom device which doesn't
# block. So, if available, use this one instead. Read the mod_ssl User
# Manual for more details.

##  SSL Global Context
##
##  All SSL configuration in this context applies both to
##  the main server and all SSL-enabled virtual hosts.
##

#   SSL Cipher Suite:
#   List the ciphers that the client is permitted to negotiate,
#   and that httpd will negotiate as the client of a proxied server.
#   See the OpenSSL documentation for a complete list of ciphers, and
#   ensure these follow appropriate best practices for this deployment.
#   httpd 2.2.30, 2.4.13 and later force-disable aNULL, eNULL and EXP ciphers,
#   while OpenSSL disabled these by default in 0.9.8zf/1.0.0r/1.0.1m/1.0.2a.
SSLCipherSuite HIGH:MEDIUM:!MD5:!RC4:!3DES
SSLProxyCipherSuite HIGH:MEDIUM:!MD5:!RC4:!3DES

#  By the end of 2016, only TLSv1.2 ciphers should remain in use.
#  Older ciphers should be disallowed as soon as possible, while the
#  kRSA ciphers do not offer forward secrecy.  These changes inhibit
#  older clients (such as IE6 SP2 or IE8 on Windows XP, or other legacy
#  non-browser tooling) from successfully connecting.  
#
#  To restrict mod_ssl to use only TLSv1.2 ciphers, and disable
#  those protocols which do not support forward secrecy, replace
#  the SSLCipherSuite and SSLProxyCipherSuite directives above with
#  the following two directives, as soon as practical.
# SSLCipherSuite HIGH:MEDIUM:!SSLv3:!kRSA
# SSLProxyCipherSuite HIGH:MEDIUM:!SSLv3:!kRSA

#   User agents such as web browsers are not configured for the user's
#   own preference of either security or performance, therefore this
#   must be the prerogative of the web server administrator who manages
#   cpu load versus confidentiality, so enforce the server's cipher order.
SSLHonorCipherOrder on 

#   SSL Protocol support:
#   List the protocol versions which clients are allowed to connect with.
#   Disable SSLv3 by default (cf. RFC 7525 3.1.1).  TLSv1 (1.0) should be
#   disabled as quickly as practical.  By the end of 2016, only the TLSv1.2
#   protocol or later should remain in use.
SSLProtocol all -SSLv3
SSLProxyProtocol all -SSLv3

#   Pass Phrase Dialog:
#   Configure the pass phrase gathering process.
#   The filtering dialog program (`builtin' is an internal
#   terminal dialog) has to provide the pass phrase on stdout.
SSLPassPhraseDialog  builtin

#   Inter-Process Session Cache:
#   Configure the SSL Session Cache: First the mechanism 
#   to use and second the expiring timeout (in seconds).
#SSLSessionCache         "dbm:@exp_runtimedir@/ssl_scache"
SSLSessionCache        "shmcb:@exp_runtimedir@/ssl_scache(512000)"
SSLSessionCacheTimeout  300

#   OCSP Stapling (requires OpenSSL 0.9.8h or later)
#
#   This feature is disabled by default and requires at least
#   the two directives SSLUseStapling and SSLStaplingCache.
#   Refer to the documentation on OCSP Stapling in the SSL/TLS
#   How-To for more information.
#
#   Enable stapling for all SSL-enabled servers:
#SSLUseStapling On

#   Define a relatively small cache for OCSP Stapling using
#   the same mechanism that is used for the SSL session cache
#   above.  If stapling is used with more than a few certificates,
#   the size may need to be increased.  (AH01929 will be logged.)
#SSLStaplingCache "shmcb:@exp_runtimedir@/ssl_stapling(32768)"

#   Seconds before valid OCSP responses are expired from the cache
#SSLStaplingStandardCacheTimeout 3600

#   Seconds before invalid OCSP responses are expired from the cache
#SSLStaplingErrorCacheTimeout 600

#   SSL Engine Switch:
#   Enable/Disable SSL for this virtual host.
SSLEngine on

#   Server Certificate:
#   Point SSLCertificateFile at a PEM encoded certificate.  If
#   the certificate is encrypted, then you will be prompted for a
#   pass phrase.  Note that a kill -HUP will prompt again.  Keep
#   in mind that if you have both an RSA and a DSA certificate you
#   can configure both in parallel (to also allow the use of DSA
#   ciphers, etc.)
#   Some ECC cipher suites (http://www.ietf.org/rfc/rfc4492.txt)
#   require an ECC certificate which can also be configured in
#   parallel.
SSLCertificateFile "@exp_sysconfdir@/server.crt"
#SSLCertificateFile "@exp_sysconfdir@/server-dsa.crt"
#SSLCertificateFile "@exp_sysconfdir@/server-ecc.crt"

#   Server Private Key:
#   If the key is not combined with the certificate, use this
#   directive to point at the key file.  Keep in mind that if
#   you've both a RSA and a DSA private key you can configure
#   both in parallel (to also allow the use of DSA ciphers, etc.)
#   ECC keys, when in use, can also be configured in parallel
SSLCertificateKeyFile "@exp_sysconfdir@/server.key"
#SSLCertificateKeyFile "@exp_sysconfdir@/server-dsa.key"
#SSLCertificateKeyFile "@exp_sysconfdir@/server-ecc.key"

#   Server Certificate Chain:
#   Point SSLCertificateChainFile at a file containing the
#   concatenation of PEM encoded CA certificates which form the
#   certificate chain for the server certificate. Alternatively
#   the referenced file can be the same as SSLCertificateFile
#   when the CA certificates are directly appended to the server
#   certificate for convenience.
#SSLCertificateChainFile "@exp_sysconfdir@/server-ca.crt"

#   Certificate Authority (CA):
#   Set the CA certificate verification path where to find CA
#   certificates for client authentication or alternatively one
#   huge file containing all of them (file must be PEM encoded)
#   Note: Inside SSLCACertificatePath you need hash symlinks
#         to point to the certificate files. Use the provided
#         Makefile to update the hash symlinks after changes.
#SSLCACertificatePath "@exp_sysconfdir@/ssl.crt"
#SSLCACertificateFile "@exp_sysconfdir@/ssl.crt/ca-bundle.crt"

#   Certificate Revocation Lists (CRL):
#   Set the CA revocation path where to find CA CRLs for client
#   authentication or alternatively one huge file containing all
#   of them (file must be PEM encoded).
#   The CRL checking mode needs to be configured explicitly
#   through SSLCARevocationCheck (defaults to "none" otherwise).

#   Client Authentication (Type):
#   Client certificate verification type and depth.  Types are
#   none, optional, require and optional_no_ca.  Depth is a
#   number which specifies how deeply to verify the certificate
#   issuer chain before deciding the certificate is not valid.
#SSLVerifyClient require
#SSLVerifyDepth  10

#   TLS-SRP mutual authentication:
#   Enable TLS-SRP and set the path to the OpenSSL SRP verifier
#   file (containing login information for SRP user accounts). 
#   Requires OpenSSL 1.0.1 or newer. See the mod_ssl FAQ for
#   detailed instructions on creating this file. Example:
#   "openssl srp -srpvfile @exp_sysconfdir@/passwd.srpv -add username"
#SSLSRPVerifierFile "@exp_sysconfdir@/passwd.srpv"

#   Access Control:
#   With SSLRequire you can do per-directory access control based
#   on arbitrary complex boolean expressions containing server
#   variable checks and other lookup directives.  The syntax is a
#   mixture between C and Perl.  See the mod_ssl documentation
#   for more details.
#
#SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
#            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
#            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
#            and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
#            and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20       ) \
#           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
#

#   SSL Engine Options:
#   Set various options for the SSL engine.
#   o FakeBasicAuth:
#     Translate the client X.509 into a Basic Authorisation.  This means that
#     the standard Auth/DBMAuth methods can be used for access control.  The
#     user name is the `one line' version of the client's X.509 certificate.
#     Note that no password is obtained from the user. Every entry in the user
#     file needs this password: `xxj31ZMTZzkVA'.
#   o ExportCertData:
#     This exports two additional environment variables: SSL_CLIENT_CERT and
#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
#     server (always existing) and the client (only existing when client
#     authentication is used). This can be used to import the certificates
#     into CGI scripts.
#   o StdEnvVars:
#     This exports the standard SSL/TLS related `SSL_*' environment variables.
#     Per default this exportation is switched off for performance reasons,
#     because the extraction step is an expensive operation and is usually
#     useless for serving static content. So one usually enables the
#     exportation for CGI and SSI requests only.
#   o StrictRequire:
#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
#     under a "Satisfy any" situation, i.e. when it applies access is denied
#     and no other module can change it.
#   o OptRenegotiate:
#     This enables optimized SSL connection renegotiation handling when SSL
#     directives are used in per-directory context. 
#SSLOptions +FakeBasicAuth +ExportCertData +StrictRequire

    SSLOptions +StdEnvVars

#   SSL Protocol Adjustments:
#   The safe and default but still SSL/TLS standard compliant shutdown
#   approach is that mod_ssl sends the close notify alert but doesn't wait for
#   the close notify alert from client. When you need a different shutdown
#   approach you can use one of the following variables:
#   o ssl-unclean-shutdown:
#     This forces an unclean shutdown when the connection is closed, i.e. no
#     SSL close notify alert is sent or allowed to be received.  This violates
#     the SSL/TLS standard but is needed for some brain-dead browsers. Use
#     this when you receive I/O errors because of the standard approach where
#     mod_ssl sends the close notify alert.
#   o ssl-accurate-shutdown:
#     This forces an accurate shutdown when the connection is closed, i.e. a
#     SSL close notify alert is send and mod_ssl waits for the close notify
#     alert of the client. This is 100% SSL/TLS standard compliant, but in
#     practice often causes hanging connections with brain-dead browsers. Use
#     this only for browsers where you know that their SSL implementation
#     works correctly. 
#   Notice: Most problems of broken clients are also related to the HTTP
#   keep-alive facility, so you usually additionally want to disable
#   keep-alive for those clients, too. Use variable "nokeepalive" for this.
#   Similarly, one has to force some clients to use HTTP/1.0 to workaround
#   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
#   "force-response-1.0" for this.
BrowserMatch "MSIE [2-5]" \
         nokeepalive ssl-unclean-shutdown \
         downgrade-1.0 force-response-1.0

#   Per-Server Logging:
#   The home of a custom SSL log file. Use this when you want a
#   compact non-error SSL logfile on a virtual host basis.
CustomLog "@exp_logfiledir@/ssl_request_log" \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

# Settings for hosting different languages.
#
# Required modules: mod_mime, mod_negotiation

# DefaultLanguage and AddLanguage allows you to specify the language of 
# a document. You can then use content negotiation to give a browser a 
# file in a language the user can understand.
#
# Specify a default language. This means that all data
# going out without a specific language tag (see below) will 
# be marked with this one. You probably do NOT want to set
# this unless you are sure it is correct for all cases.
#
# * It is generally better to not mark a page as 
# * being a certain language than marking it with the wrong
# * language!
#
# DefaultLanguage nl
#
# Note 1: The suffix does not have to be the same as the language
# keyword --- those with documents in Polish (whose net-standard
# language code is pl) may wish to use "AddLanguage pl .po" to
# avoid the ambiguity with the common suffix for perl scripts.
#
# Note 2: The example entries below illustrate that in some cases 
# the two character 'Language' abbreviation is not identical to 
# the two character 'Country' code for its country,
# E.g. 'Danmark/dk' versus 'Danish/da'.
#
# Note 3: In the case of 'ltz' we violate the RFC by using a three char
# specifier. There is 'work in progress' to fix this and get
# the reference data for rfc1766 cleaned up.

#
# Required modules: mod_log_config

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# 
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any  block.

=============

`mod_lua` version of the Apache httpd's mod_status using dynamic charts

## What does it do? ##
This script is an extended version of the known mod_status statistics page for httpd.
It uses the simple Quokka Chart API to visualize many of the elements that are sometimes hard 
to properly diagnose using plain text information.

Take a look at https://www.apache.org/server-status to see how it works.

## Requirements ##
* Apache httpd 2.4.6 or higher
* mod_lua (with either Lua 5.1, 5.2 or LuaJIT)
* mod_status loaded (for enabling traffic statistics)

## Installing ##
First, install mod_lua (you can enable this during configure time with --enable-lua)

### Installing as a handler:
To install it as a handler, add the following to your httpd.conf in the appropriate VirtualHost:

    LuaMapHandler ^/server-status$ /path/to/server-status.lua
    
### Installing as a web app:
To install as a plain web-app, enable .lua scripts to be handled by mod_lua, by adding the following 
to your appropriate VirtualHost configuration:

    AddHandler lua-script .lua

Then just put the `.lua` script somewhere in your document root and visit the page.

## Configuring
There are a few options inside the Lua script that can be set to `true` or `false`:

- `show_warning`: Whether or not to show a notice that this page is there on purpose.
- `redact_ips`: Whether or not to replace the last few bits of every IP with 'x.x'
- `show_modules`: Whether to show the list of loaded modules or not
- `show_threads`: Whether to show thread details or not.

    Public Domain Icons
    


    These icons were originally made for Mosaic for X and have been
included in the NCSA httpd and Apache server distributions in the
past. They are in the public domain and may be freely included in any
application. The originals were done by Kevin Hughes (kevinh@kevcom.com).
Andy Polyakov tuned the icon colors and added few new images.
    


    If you'd like to contribute additions to this set, contact the httpd
documentation project http://httpd.apache.org/docs-project/.
    


    Almost all of these icons are 20x22 pixels in size.  There are
alternative icons in the "small" directory that are 16x16 in size,
provided by Mike Brown (mike@hyperreal.org).

     documentation project .

     Almost all of these icons are 20x22 pixels in size.  There are

    Das Dokument beschreibt, was ein Multi-Processing-Modul ist und wie solche
    Module beim Apache HTTP Server verwendet werden.
    

    


    top
    

    

    Einführung
    

  
    Der Apache HTTP Server wurde als leistungsfähiger und flexibler Webserver
    konzipiert, der auf einer Vielzahl von Plattformen in einer
    Reihe unterschiedlicher Umgebungen arbeiten kann. Unterschiedliche
    Plattformen und unterschiedliche Umgebungen verlangen oftmals verschiedene
    Fähigkeiten oder kennen verschiedene Wege, die gleiche
    Funktionaltät sehr effizient zu implementieren. Der Apache hat durch
    seinen modularen Aufbau schon immer eine breite Auswahl von Umgebungen
    unterstützt. Dieses Design erlaubt es dem Webmaster, durch Auswahl der
    Module, die zur Kompilierungszeit oder zur Laufzeit geladen werden, die
    Features auszuwählen, die in den Server intregiert werden.
    

  
    Der Apache 2.0 erweitert dieses modulare Design auf die grundlegenden
    Funktionen eines Webservers. Der Server wird mit einer Auswahl von
    Multi-Processing-Modulen (MPMs) ausgeliefert, die für die Bindung an
    Netzwerkports der Maschine, die Annahme von Anfragen und die Abfertigung von
    Kindprozessen zur Behandlung der Anfragen zuständig sind.
    

  
    Die Erweiterung des modularen Aufbaus auf diese Ebene des Servers
    bringt zwei wesentliche Vorteile:
    

  
      
    
    • Der Apache kann nun eine Vielfalt von Betriebssystemen sauberer und
      effizienter unterstützen. Insbesondere die Windows-Version des Apache
      ist jetzt deutlich effizienter, da mpm_winnt native
      Netzwerkfähigkeiten anstelle der im Apache 1.3 verwendeten
      POSIX-Schicht benutzen kann. Dieser Vorteil gilt auch für andere
      Betriebssysteme, für die spezielle MPMs implementiert sind.
      • 
    
    
    • Der Server läßt sich besser auf die Bedürfnisse der
      jeweiligen Website anpassen. Sites beispielsweise, die eine hohe
      Skalierbarkeit benötigen, können ein Threaded-MPM wie
      worker oder event wählen,
      während Sites, die Stabilität oder Kompatibilität mit
      älterer Software erfordern, prefork wählen
      können.
      • 
  
    

  
    Auf Anwenderebene erscheinen MPMs fast wie andere Apache-Module. Der
    Hauptunterschied ist, dass jeweils nur ein einziges MPM in den Server
    geladen werden kann. Die Liste der verfügbaren MPMs finden Sie im Modul-Index.
    


    top
    

    

    Auswahl eines MPMs
    

  
    MPMs müssen während der
    (Anm.d.Ü.: Quelltext-)Konfiguration ausgewählt und in den
    Server einkompiliert werden. Compiler sind in der Lage eine Reihe von
    Funktionen zu optimieren, wenn Threads verwendet werden. Sie können
    dies allerdings nur, wenn sie wissen, dass Threads benutzt werden.
    

  
    Um das gewünschte MPM tatsächlich auszuwählen, verwenden Sie
    beim configure-Skript das Argument
    --with-mpm=NAME. NAME ist der Name des
    gewünschten MPMs.
    

  
    Ist der Server kompiliert, so ist es mittels ./httpd -l
    möglich, das ausgewählte MPM zu ermitteln. Dieser Befehl listet
    alle in den Server einkompilierten Module auf, einschließlich des
    MPM.
    

    top
    

    

    MPM-Voreinstellungen
    

  
    Die folgende Tabelle gibt die voreingestellten MPMs für verschiedene
    Betriebssysteme an. Wenn Sie während der Kompilierung keine andere
    Auswahl treffen, wird dieses MPM gewählt.

    SuEXEC özelliği, Apache HTTP Sunucusu kullanıcılarına
      CGI ve SSI programlarını sunucunun
      aidiyetinde çalıştığı kullanıcıdan farklı bir kullanıcının aidiyetinde
      çalıştırma olanağı verir. Normalde, CGI ve
      SSI programlarını çalıştıranla sunucuyu çalıştıran
      aynı kullanıcıdır.
    

    
    Gerektiği gibi kullanıldığında bu özellik, kullanıcılara
      CGI ve SSI programlarını çalıştırma
      ve geliştirmeye izin vermekle ortaya çıkan güvenlik risklerini azaltır.
      Bununla birlikte, suEXEC gerektiği gibi
      yapılandırılmadığı takdirde bazı sorunlara yol açabilir ve bilgisayar
      güvenliğinizde yeni delikler ortaya çıkmasına sebep olabilir.
      Güvenlikle ilgili mevcut sorunlarla başa çıkmada ve setuid
      root programları yönetmekte bilgi ve deneyim sahibi değilseniz
      suEXEC kullanmayı kesinlikle düşünmemenizi
      öneririz.

    Başlamadan önce
    

    
    Belgeye balıklama dalmadan önce, suexec'i kullanacağınız ortam ve
      kendiniz hakkında yapılmış çeşitli kabuller hakkında bilgi sahibi
      olmalısınız.
    

    
    Öncelikle, üzerinde setuid va setgid
      işlemlerinin yapılabildiği Unix türevi bir işletim sistemi
      kullandığınızı varsayıyoruz. Tüm komut örnekleri buna dayanarak
      verilmiştir. Bu desteğe sahip başka platformlar varsa onlardaki
      yapılandırma burada anlattığımız yapılandırmadan farklı olabilir.
    

    
    İkinci olarak, bilgisayarınızın güvenliği ve yönetimi ile ilgili bazı
      temel kavramları bildiğinizi kabul ediyoruz. Buna
      setuid/setgid işlemlerinin sisteminiz ve güvenlik
      seviyesi üzerindeki etkilerini bilmek dahildir.
    

    
    Üçüncü olarak, suEXEC kodunun
      değiştirilmemiş bir sürümünü kullandığınızı
      varsayıyoruz. Tüm suEXEC kodu, geliştiricilerin yanında sayısız beta
      kullanıcısı tarafından dikkatle incelenmiş ve denenmiştir. Kodların hem
      basit hem de sağlam bir şekilde güvenli olması için gerekli tüm
      önlemler alınmıştır. Bu kodun değiştirilmesi beklenmedik sorunlara ve
      yeni güvenlik risklerine yol açabilir. Özellikle güvenlikle ilgili
      programlarda deneyimli değilseniz suEXEC kodunda kesinlikle bir
      değişiklik yapmamalısınız. Değişiklik yaparsanız kodlarınızı gözden
      geçirmek ve tartışmak üzere Apache HTTP Sunucusu geliştirme ekibi ile
      paylaşmanızı öneririz.
    

    
    Dördüncü ve son olarak, Apache HTTP Sunucusu geliştirme ekibinin
      suEXEC’i öntanımlı httpd kurulumunun bir parçası yapmama kararından
      bahsetmek gerekir. Bunun sonucu olarak, suEXEC yapılandırması sistem
      yöneticisinin ayrıntılı bir incelemesini gerektirir. Gerekli incelemeden
      sonra yönetici tarafından suEXEC yapılandırma seçeneklerine karar
      verilip, normal yollardan sisteme kurulumu yapılır. Bu seçeneklerin
      belirlenmesi, suEXEC işlevselliğinin kullanımı sırasında sistem
      güvenliğini gerektiği gibi sağlamak için yönetici tarafından dikkatle
      saptanmayı gerektirir. Bu sürecin ayrıntılarının yöneticiye bırakılma
      sebebi, suEXEC kurulumunu, suEXEC’i dikkatle kullanacak yeterliliğe sahip
      olanlarla sınırlama  beklentimizdir.

    SuEXEC Güvenlik Modeli
    

    
    SuEXEC yapılandırması ve kurulumuna girişmeden önce biraz da
      gerçekleşmesini istediğiniz güvenlik modelinin ayrıntıları üzerinde
      duralım. Böylece, suEXEC’in içinde olup bitenleri ve sisteminizin
      güvenliği için alınacak önlemleri daha iyi anlayabilirsiniz.
    

    
    suEXEC işlevselliği, Apache HTTP Sunucusu tarafından
      gerektiği takdirde artalanda çalıştırılan bir setuid programa dayanır.
      Bu program, bir CGI veya SSI betiğine bir HTTP isteği yapıldığı zaman,
      bu betiği, yöneticinin ana sunucunun aidiyetinde çalıştığı kullanıcıdan
      farklı olarak seçtiği bir kullanıcının aidiyetinde çalıştırmak için
      çağrılır. Böyle bir istek geldiğinde, Apache httpd artalandaki setuid
      programına, HTTP isteği yapılan programın ismiyle beraber aidiyetinde
      çalışacağı kullanıcı ve grup kimliklerini de aktarır.
    

    
    Artalanda çalıştırılan setuid program başarıyı ve başarısızlığı
      aşağıdaki süreci izleyerek saptar. Bunlardan herhangi biri başarısız
      olursa program başarısızlık durumunu günlüğe kaydeder ve bir hata
      vererek çıkar. Aksi takdirde çalışmaya devam eder.
    

    
      
      
    1. 
        Setuid programı çalıştıran kullanıcı sistemin geçerli
        kullanıcılarından biri mi?

        
      Bu, setuid programı çalıştıran kullanıcının
        sistemin gerçek bir kullanıcısı olduğunudan emin olunmasını sağlar.
        
      
     
      2. 

     
    2. 
        Setuid program yeterli sayıda argümanla çağrılmış mı?
        

        
      Apache HTTP Sunucusunun artalanda çağırdığı
          setuid program ancak yeterli sayıda argüman sağlandığı takdirde
          çalışacaktır. Argümanların sayısını ve sırasını Apache HTTP sunucusu
          bilir. Eğer setuid program yeterli sayıda argümanla çağrılmamışsa
          ya kendisinde bir değişiklik yapılmıştır ya da kurulu Apache httpd
          çalıştırılabilirinin suEXEC ile ilgili kısmında yanlış giden bir
          şeyler vardır.
      
      
      3. 

      
    3. 
        Bu geçerli kullanıcının bu setuid programı çalıştırma
          yetkisi var mı?

        
      Sadece tek bir kullanıcı (Apache’nin aidiyetinde
          çalıştığı kullanıcı) bu programı çalıştırmaya yetkilidir.
      
      
      4. 

      
    4. 
        Hedef CGI veya SSI programı hiyerarşik olarak güvenliği
          bozacak bir dosya yolu üzerinde mi?

        
      Hedef CGI veya SSI programının dosya yolu '/' veya
          '..' ile başlıyor  mu? Buna izin verilmez. Hedef CGI veya SSI
          programı suEXEC’in belge kök dizininde yer almalıdır (aşağıda
          --with-suexec-docroot=DİZİN seçeneğine
          bakınız).
      
      
      5. 

      
    5. 
        Hedef kullanıcı ismi geçerli mi?

        
      Hedef kullanıcı mevcut mu?
      
      
      6. 

      
    6. 
        Hedef grup ismi geçerli mi?

        
      Hedef grup mevcut mu?
      
      
      7. 

      
    7. 
        Hedef kullanıcı root değil, değil mi?

        
      Mevcut durumda, root kullanıcısının
          CGI/SSI programlarını çalıştırmasına izin verilmemektedir.
      
      
      8. 

      
    8. 
        Hedef kullanıcı kimliği asgari kullanıcı numarasından
          BÜYÜK mü?

        
      Asgari kullanıcı numarası yapılandırma sırasında
          belirtilir. Böylece CGI/SSI programlarını çalıştırmasına izin
          verilecek olası en düşük kullanıcı numarasını belirlemeniz mümkün
          kılınmıştır. Bu bazı “sistem” hesaplarını devreden çıkarmak için
          yararlıdır.
      
      
      9. 

      
    9. 
        Hedef grup root  değil, değil mi?

        
      root grubunun CGI/SSI
          programlarını çalıştırmasına izin verilmemektedir.
      
      
      10. 

      
    10. 
        Hedef grup numarası asgari grup numarasından
          BÜYÜK mü?

        
      Asgari grup numarası yapılandırma sırasında
          belirtilir. Böylece CGI/SSI programlarını çalıştırmasına izin
          verilecek olası en düşük grup numarasını belirlemeniz mümkün
          kılınmıştır. Bu bazı “sistem” hesaplarını devreden çıkarmak için
          yararlıdır.
      
      
      11. 

      
    11. 
        Apache’nin artalanda çağırdığı setuid program hedef
          kullanıcı ve grubun aidiyetine geçebildi mi?

        
      Bu noktadan itibaren program setuid ve setgid
          çağrıları üzerinden hedef kullanıcı ve grubun aidiyetine geçer.
          Erişim grubu listesi de ayrıca kullanıcının üyesi olduğu tüm
          gruplara genişletilir.
      
      
      12. 

      
    12. 
        Hedef CGI/SSI programının bulunduğu dizine geçebildik mi?
        

        
      Dizin mevcut değilse dosyaları da içeremez. Hedef
          dizine geçemiyorsak bu, dizin mevcut olmadığından olabilir.
      
      
      13. 

      
    13. 
        Hedef dizin Apache için izin verilen yerlerden biri mi?
        

        
      İstek sunucunun normal bir bölümü için yapılmış
          olsa da istenen dizin acaba suEXEC’in belge kök dizini altında mı?
          Yani, istenen dizin, suEXEC’in aidiyetinde çalıştığı kullanıcının
          ev dizini altında bulunan, UserDir ile belirtilen dizinin altında mı? (suEXEC’in yapılandırma seçeneklerine
          bakınız).
      
      
      14. 

      
    14. 
        Hedef dizin başkaları tarafından yazılabilen bir dizin değil,
          değil mi?

        
      Başkaları da yazabilsin diye bir dizin açmıyoruz;
          dizin içeriğini sadece sahibi değiştirebilmelidir.
      
      
      15. 

      
    15. 
        Hedef CGI/SSI programı mevcut mu?

        
      Mevcut değilse çalıştırılamaz.
      
      
      16. 

      
    16. 
        Hedef CGI/SSI program dosyasına başkaları tarafından
          yazılamıyor, değil mi?

        
      Hedef CGI/SSI programının dosyasına sahibinden
          başka kimsenin bir şeyler yazmasını istemeyiz.
      
      
      17. 

      
    17. 
        Hedef CGI/SSI program setuid veya setgid değil,
          değil mi?

        
      UID/GID‘i tekrar değiştirecek programlar
          çalıştırmayı istemeyiz.
      
      
      18. 

      
    18. 
        Hedef kullanıcı/grup, programın kullanıcı/grubu ile aynı mı?
        

        
      Hedef kullanıcı dosyanın sahibi mi?
      
      
      19. 

      
    19. 
        İşlemlerin güvenle yapılabilmesi için süreç ortamını
          başarıyla temizleyebildik mi?

        
      suEXEC, sürecin çalışacağı ortama güvenli bir
          program çalıştırma yolu sağlamaktan başka, yapılandırma sırasında
          oluşturulan güvenli ortam değişkenleri listesinde isimleri bulunan
          ortam değişkenlerinden başkasını aktarmayacaktır.
      
      
      20. 

      
    20. 
        Hedef CGI/SSI programı haline gelip çalışabildik mi?

        
      Burası suEXEC’in bitip CGI/SSI programının
          başladığı yerdir.
      
      
      21. 
    
    

    
    Bu süreç suEXEC güvenlik modelinin standart işlemlerini oluşturur.
      Biraz zorlayıcı ve CGI/SSI tasarımına yeni kurallar ve sınırlamalar
      getiriyor olsa da düşünülen güvenliği adım adım sağlayacak şekilde
      tasarlanmıştır.
    

    
    Düzgün bir suEXEC yapılandırmasının hangi güvenlik risklerinden
      kurtulmayı sağladığı ve bu güvenlik modelinin sunucu yapılandırmasıyla
      ilgili sorumluluklarınızı nasıl sınırlayabildiği hakkında daha
      ayrıntılı bilgi edinmek için bu belgenin "Uyarılar ve Örnekler" bölümüne bakınız.

    suEXEC’in Yapılandırılması ve Kurulumu
    

    
    Eğlence başlıyor.
    

    
    suEXEC yapılandırma seçenekleri
    
    
    

    
    
      
    --enable-suexec
    

      
    Bu seçenek, hiçbir zaman öntanımlı olarak kurulmayan ve
        etkinleştirilmeyen suEXEC özelliğini etkin kılar. suEXEC özelliğini
        kullanma isteğinizi Apache’nin kabul edebilmesi için
        --enable-suexec seçeneğinin yanında en azından bir tane
        de --with-suexec-xxxxx seçeneği belirtilmiş
        olmalıdır.
    

      
    --with-suexec-bin=YOL
    

      
    Güvenlik sebebiyle suexec çalıştırılabilirinin
        bulunduğu yer sunucu koduna yazılır. Bu seçenekle öntanımlı yol
        değiştirilmiş olur. Örnek:
    
        --with-suexec-bin=/usr/sbin/suexec
    

      
    --with-suexec-caller=KULLANICI
    

      
    Normalde httpd’nin aidiyetinde çalıştığı kullanıcıdır. Bu, suEXEC
        çalıştırıcısını çalıştırmasına izin verilen tek kullanıcıdır.
    

      
    --with-suexec-userdir=DİZİN
    

      
    Kullanıcıların ev dizinleri altında suEXEC’in erişmesine izin
        verilen alt dizinin yerini tanımlar. Bu dizin altında suEXEC
        kullanıcısı tarafından çalıştırılacak tüm programlar "güvenilir"
        olmalıdır. Eğer “basit” bir UserDir yönergesi kullanıyorsanız ( içinde “*”
        bulunmayan), bunun aynı dizin olması gerekir. Eğer burada belirtilen
        dizin, passwd dosyasında kullanıcı için belirtilmiş
        dizinin altında UserDir
        yönergesinde belirtilen dizin olmadığı takdirde suEXEC işini
        gerektiği gibi yapmayacaktır. Öntanımlı değer
        public_html’dir.
    

      
    Eğer, sanal konaklarınızın herbiri farklı UserDir yönergeleri içeriyorsa
        burada belirtilecek dizinin üst dizininin hepsinde aynı olması
        gerekir. Aksi takdirde, "~kullanıcı"
        istekleri düzgün çalışmayacaktır.
    

      
    --with-suexec-docroot=DİZİN
    

      
    httpd için belge kök dizinini belirler. Bu, (UserDir’lardan başka) suEXEC için
        kullanılacak tek hiyerarşi olacaktır. Öntanımlı dizin sonuna
        "/htdocs" eklenmiş --datadir dizinidir.
        Yani, seçeneği "--datadir=/home/apache" olarak
        belirtmişseniz suEXEC çalıştırıcısı için belge kök dizini
        "/home/apache/htdocs" olur.
    

      
    --with-suexec-uidmin=UID
    

      
    suEXEC kullanıcısının kullanıcı kimliği olarak izin verilen en
        düşük değeri belirler. Çoğu sistemde bu ya 500’dür ya da 100; 100
        öntanımlıdır.
    

      
    --with-suexec-gidmin=GID
    

      
    suEXEC kullanıcısının grup kimliği olarak izin verilen en düşük
        değeri belirler. Çoğu sistemde bu 100 olup, seçeneğin de öntanımlı
        değeridir.
    

      
    --with-suexec-logfile=DOSYA
    

      
    suEXEC hareketlerinin ve hatalarının kaydedileceği günlük
        dosyasının adını belirler (denetim ve hata ayıklama için
        kullanışlıdır). Öntanımlı günlük dosyası ismi
        "suexec_log" olup yeri (--logfiledir
        seçeneği ile belirtilen) günlük dosyaları dizinidir.
    

      
    --with-suexec-safepath=YOL
    

      
    CGI çalıştırılabilirlerine aktarılacak güvenilir PATH
        ortam değişkeninin değerini tanımlar.
        "/usr/local/bin:/usr/bin:/bin" öntanımlıdır.
    
    
    

    
    SuEXEC çalıştırıcısının derlenmesi ve kurulumu
    
      

      
    SuEXEC özelliğini --enable-suexec seçeneği ile
        etkinleştirdiyseniz make komutunu verdiğinizde httpd
        ile birlikte suexec çalıştırılabilir dosyası da
        derlenecektir.
    

      
    Tüm bileşenler derlendikten sonra make install komutunu
        vererek kurulumu tamamlayabilirsiniz. suexec
        çalıştırılabilir dosyası --sbindir seçeneği ile
        tanımlanan dizine kurulacaktır; öntanımlı yeri
        /usr/local/apache2/bin/ dizinidir.
    

      
    Kurulum adımında root yetkisine sahip
        olmanız gerektiğini unutmayın. Çalıştırıcıya kullanıcı kimliğinin
        atanabilmesi ve dosyanın sahibi olan kullanıcı kimliği ile
        çalıştırılabilmesini mümkün kılan bitinin etkin kılınabilmesi için
        kurulumun root tarafından yapılması
        önemlidir.
    
    

    
    Paranoyak yetkilendirme
    
      

      
    SuEXEC çalıştırıcısı kendini çalıştıran kullanıcının
        configure betiğine
        --with-suexec-caller seçeneği ile belirtilen kullanıcı
        olup olmadığına bakacaksa da, bu sınamanın da bir sistem veya
        kütüphane çağrısı ile istismar edilmiş olma ihtimali gözardı
        edilmemelidir. Bunun meydana gelmesini önlemek için ve genelde
        yapıldığı gibi dosyanın izinlerini suEXEC çalıştırıcısı sadece
        httpd'nin aidiyetinde çalıştığı grup tarafından çalıştırılacak
        şekilde ayarlayınız.
    

      
    Örneğin, sunucunuz şöyle yapılandırılmışsa:
    

      
    User www
Group webgroup
    


      
    Ve suexec çalıştırılabilir de
        /usr/local/apache2/bin/ dizinine kurulmuşsa şu komutları
        vermelisiniz:
    

      
    
          chgrp apache-grup /usr/local/apache2/bin/suexec
    
          chmod 4750 /usr/local/apache2/bin/suexec
    
      
    

      
    Böylece suEXEC çalıştırıcısını httpd’yi çalıştıran grubun
        üyelerinden başkasının çalıştıramayacağından emin olabilirsiniz.
    
    

    top
    

    

    suEXEC’in etkin kılınması ve iptal edilmesi
    
    

    
    httpd başlatıldığı sırada suexec çalıştırıcısı için
      --sbindir seçeneği ile tanımlanan dizine bakar (seçeneğin
      öntanımlı değeri /usr/local/apache/sbin/suexec’tir). httpd
      düzgün yapılandırılmış bir suEXEC çalıştırıcısı bulduğu takdirde hata
      günlüğüne şöyle bir ileti yazacaktır:
    


    
    [notice] suEXEC mechanism enabled (wrapper: /dosya/yolu/suexec)

    

    
    Sunucu başlatıldığında bu ileti yazılmazsa sunucu ya çalıştırıcı
      programı umduğu yerde bulamamıştır ya da dosyanın setuid biti
      root tarafından etkin kılınmamıştır.
    

     
    SuEXEC mekanizmasını etkin kılmak istediğiniz sunucu çalışmaktaysa
      sunucuyu önce öldürmeli sonra yeniden başlatmalısınız.  Basit bir
      HUP veya USR1 sinyali ile yeniden başlamasını
      sağlamak yeterli olmayacaktır.
    

     
    SuEXEC mekanizmasını iptal etmek için ise suexec
      dosyasını sildikten sonra httpd'yi öldürüp yeniden başlamalısınız.
    

    top
    

    

    SuEXEC’in kullanımı
    

    
    CGI programlarına yapılan isteklerin suEXEC çalıştırıcısı tarafından
      yerine getirilebilmesi için sanal konağın bir SuexecUserGroup yönergesi içermesi veya
      isteğin mod_userdir tarafından işleme konulması
      gerekir.
    

    
    Sanal Konaklar:
    SuEXEC çalıştırıcısını farklı
      bir kullanıcı ile etkin kılmanın tek yolu VirtualHost bölümleri içinde SuexecUserGroup yönergesini
      kullanmaktır. Bu yönergede ana sunucuyu çalıştıran kullanıcıdan farklı
      bir kullanıcı  belirterek ilgili sanal konak üzerinden CGI kaynakları
      için yapılan tüm isteklerin belirtilen kullanıcı ve
      grup tarafından çalıştırılması sağlanır. Bu yönergeyi
      içermeyen sanal konaklar için ana sunucunun kullanıcısı
      öntanımlıdır.
    

    
    Kullanıcı dizinleri:
    
    mod_userdir tarafından işleme sokulan tüm istekler için
    suEXEC çalıştırıcısı istek yapılan kullanıcı dizininin sahibinin
    aidiyetinde çalıştırılacaktır. Bu özelliğin çalışması için tek
    gereklilik, kullanıcının SuEXEC çalıştırıcısı için etkin kılınmış olması
    ve çalıştırıcının yukarıdaki güvenlik sınamalarından
    geçebilmesidir. Ayrıca,  --with-suexec-userdir derleme seçeneğinin açıklamasına da bakınız.
    

    top
    

    

    SuEXEC ve hata ayıklama
    

    
    SuEXEC çalıştırıcısı yukarıda değinildiği gibi günlük bilgilerini
      --with-suexec-logfile seçeneği ile belirtilen dosyaya
      yazacaktır. Çalıştırıcıyı doğru yapılandırarak kurduğunuzdan emin olmak
      istiyorsanız, yolunda gitmeyen şeyler var mı diye bu günlük dosyasına
      bakmayı ihmal etmeyin.

    Uyarılar ve Örnekler
    
    

    
    UYARI! Bu bölüm henüz bitmedi.
    

    
    SuEXEC çalıştırıcısından dolayı sunucu ayarlarına bazı sınırlamalar
      getiren bir kaç önemli nokta mevcuttur. SuEXEC ile ilgili hata
      bildiriminde bulunmadan önce bunlara bir göz atmalısınız.
    

    
    suEXEC ile ilgili önemli noktalar
      
    
      
      
    • Hiyerarşik sınırlamalar

        
      Güvenlik ve verimlilik adına, tüm suEXEC
          isteklerinin sanal konaklar için üst düzey belge kökünün altındaki
          dosyalarla, kullanıcı dizinleri için ise üst düzey bireysel belge
          köklerinin altındaki dosyalarla sınırlı kalması gerekir. Örneğin,
          dört sanal konağınız varsa ve suEXEC çalıştırıcısının
          getirilerinden faydalanmak istiyorsanız, sanal konaklarınızın belge
          kök dizinlerini ana sunucunun belge kök dizininin altında kalacak
          şekilde yapılandırmanız gerekir (örnek yolda).
      
      
      • 

      
    • SuEXEC'in PATH ortam değişkeni

        
      Bunu değiştirmek tehlikeli olabilir. Bu değişkende
          tanımladığınız her yolun güvenli bir dizini işaret
          ettiğinden emin olmalısınız. Başkalarının oralarda bir truva atı
          çalıştırmasını istemiyorsanız buna çok dikkat ediniz.

    Améliorations du noyau
    
    
    
    
      
    Modules multiprocessus (MPMs) chargeables à l'exécution
    
      
    Plusieurs MPMs peuvent maintenant être compilés en tant que modules
      chargeables. Le choix du MPM à utiliser s'effectue
      à l'exécution via la directive LoadModule.
    

      
    MPM Event
    
      
    Le MPM Event n'en est plus au stade expérimental et est
      maintenant pleinement supporté.
    

      
    Support du mode asynchrone
    
      
    Le support des lectures/écritures asynchrones pour les MPMs et
      les plateformes qui l'implémentent a été amélioré.
    

      
    Configuration du niveau de journalisation (LogLevel) par
      module et par répertoire
    
      
    La directive LogLevel
      peut maintenant être définie par module et par répertoire. Les
      nouveaux niveaux trace1 à trace8 ont été
      ajoutés au dessus du niveau de journalisation debug.
    

      
    Sections de configuration au niveau requête
    
      
    Les sections If,
      <ElseIf> et
      <Else>
      permettent de définir une configuration en fonction de critères
      liés à la requête.
    

      
    Interpréteur d'expressions à usage général
    
      
    Un nouvel interpréteur d'expressions permet de spécifier des
      conditions complexes via des directives à
      syntaxe commune comme SetEnvIfExpr, RewriteCond, Header,
      <If>, etc...
      
    

      
    KeepAliveTimeout en millisecondes
    
      
    Il est maintenant possible de définir la directive KeepAliveTimeout en millisecondes.
      
    

      
    Directive NameVirtualHost
    
      
    Cette directive n'est plus nécessaire et est maintenant obsolète.
    

      
    Directives autorisées dans les fichiers .htaccess
    
      
    La nouvelle directive AllowOverrideList permet de contrôler de
      manière plus précise la liste des directives autorisées dans les
      fichiers .htaccess.
    

      
    Variables dans les fichiers de configuration
    
      
    La directive Define
      permet de définir des variables dans les fichiers de
      configuration, améliorant ainsi la clareté de la présentation si
      la même valeur est utilisée en plusieurs points de la
      configuration.
      
    

      
    Diminution de la mémoire utilisée
    
      
    Bien qu'elle propose de nombreuses nouvelles fonctionnalités,
      la version 2.4.x tend à utiliser moins de mémoire que la version
      2.2.x.

    Améliorations des modules
    
    
    
    
      
    mod_ssl
    

      
    mod_ssl peut maintenant vérifier la
      validité des certificats clients en se connectant à
      un serveur OCSP. Il est possible de définir un
      répondeur par défaut, et de choisir si l'on
      préfère le répondeur désigné
      dans le certificat client.
    

	
    En outre, mod_ssl supporte maintenant
	l'estampillage OCSP (OCSP stapling), qui permet au serveur
	d'attester la validité de son certificat auprès du client au
	cours de la phase de négociation de la connexion.
    

      
    Enfin, mod_ssl peut maintenant être configuré pour
      que celui-ci partage les données de session SSL entre les serveurs
      via memcached.
    

      
    Le support des clés EC a été ajouté à celui des clés RSA et
      DSA.
    

      
    Support de TLS-SRP (disponible à partir de la version 2.4.4).
    

      
    mod_proxy
    

      
    La directive ProxyPass est maintenant configurée
      de manière optimale dans les sections Location ou LocationMatch, et offre un gain de
      performances important par rapport à la syntaxe traditionnelle à
      deux paramètres lorsqu'elle est présente en grand nombre.
    

      
    Il est maintenant possible de configurer l'adresse source dans
      les requêtes mandatées.
    

      
    Support des sockets de type Unix vers le serveur
      d'arrière-plan (disponible à partir de la version 2.4.7).
    

      
    mod_proxy_balancer
    

      
    Le gestionnaire de répartition de charge propose de nouvelles
      fonctionnalités. Ainsi, les possibilités de configuration des
      membres du groupe de répartition de charge pendant l'exécution ont
      été améliorées (possibilité d'ajout d'un membre supplémentaire).
    

      
    Configuration à l'exécution d'un sous-ensemble de paramètres
      de répartition de charge.
    

      
    Les membres du groupe de répartition peuvent être définis à
      'Drain' de façon à ce qu'ils ne répondent qu'aux sessions
      persistantes existantes, ce qui permet de les mettre hors ligne en
      douceur.
    

      
    Les règlages du répartiteur de charge peuvent être rendus
      persistants après redémarrage.
    

      
    mod_cache
    

      
    Le filtre CACHE du module mod_cache peut être
      inséré à un certain point de la chaîne de filtrage pour contrôler
      plus finement la mise en cache.
      
    

      
    mod_cache peut maintenant mettre en cache des
      requêtes HEAD.
    

      
    Chaque fois que cela est possible, les directives de
      mod_cache peuvent maintenant être définies au
      niveau du répertoire, et non plus seulement au niveau du serveur
      principal.
    

      
    L'URL de base des URLs en cache peut être personnalisée de
      façon à ce qu'un cluster de caches puisse partager le même préfixe
      d'URL.
    

      
    mod_cache peut maintenant servir du contenu
      non mis à jour lorsqu'un serveur d'arrière-plan n'est pas
      disponible (erreur 5xx).
    

      
    mod_cache peut maintenant insérer
      HIT/MISS/REVALIDATE dans un en-tête X-Cache.
    

      
    mod_include
    
      
    Support de l'attribut 'onerror' dans un élément 'include',
      permettant de renvoyer un message d'erreur personnalisé à la place
      du message d'erreur par défaut.
    

      
    mod_cgi, mod_include,
          mod_isapi, ...
    
      
    La traduction des en-têtes en variables d'environnement est
      plus stricte qu'avant, ce qui permet de diminuer l'exposition aux attaques
      de type cross-site-scripting via injection d'en-têtes. Les noms
      d'en-têtes contenant des caractères invalides (comme les caractères
      de soulignement) ne sont plus convertis en variables d'environnement. Le document Les variables d'environnement dans Apache
      présente quelques pistes pour contourner ce problème avec les
      clients anciens qui nécessitent de tels en-têtes (Ceci affecte
      tous les modules qui utilisent ces variables d'environnement).
    

      
    mod_authz_core Conteneurs de logique d'autorisation
    

      
    La directive Require et les directives de
      conteneurs associées, comme <RequireAll>, permettent de définir une
      logique d'autorisation avancée.
    

      

      
    mod_rewrite
    
      
    La directive RewriteRule dispose maintenant
      des drapeaux [QSD] (Query String Discard) et
      [END] qui permettent de simplifier les scénarios de
      réécriture courants.
    
      
    Possibilité d'utiliser des expressions booléennes complexes
      dans la directive RewriteCond.
    
      
    Possibilité d'utiliser des requêtes SQL en tant que fonctions
      dans la directive RewriteMap.
    

      
    mod_ldap, mod_authnz_ldap
    
      
    mod_authnz_ldap ajoute le support des
      groupes imbriqués.
    
      
    mod_ldap apporte les directives LDAPConnectionPoolTTL et LDAPTimeout, ainsi que d'autres
      améliorations dans le traitement des délais. Ceci s'avère utile
      pour les configurations où un pare-feu à mémoire d'état (stateful)
      rejète les connexions inactives vers le serveur LDAP.
    
      
    mod_ldap propose la directive LDAPLibraryDebug qui permet de
      journaliser les informations de débogage fournies par la boîte à
      outils LDAP utilisée.
    

      
    mod_info
    
      
    mod_info est maintenant capable d'afficher la
      configuration préinterprétée sur stdout au cours du démarrage du
      serveur.
    

      
    mod_auth_basic
    
      
    Nouveau mécanisme générique permettant d'effectuer une
      authentification basique (disponible à partir de la version 2.4.5).

    Améliorations des programmes
    
    
    
    
        
    fcgistarter
    
        
    Nouvel utilitaire pour le démarrage des démons
	FastCGI.
    
	
    htcacheclean
    
        
    Les URLs présentes dans le cache peuvent maintenant être
	affichées, accompagnées éventuellement de leurs métadonnées.
    
        
    Possibilité de supprimer explicitement des URLs individuelles
	présentes dans le cache.
    
        
    Les tailles de fichiers peuvent maintenant être arrondies au
	multiple de la taille de bloc donnée, les limites de taille
	collant de ce fait d'avantage à la taille réelle sur disque.
    
        
    La taille du cache peut maintenant être limitée par le
	nombre d'inodes, en plus de la possibilité de limitation par la
	taille des fichiers.
    

	
    rotatelogs
    
        
    Possibilité de créer un lien vers le fichier journal
	courant.
    
        
    Possibilité d'invoquer un script personnalisé après la
	rotation.
    

	
    htpasswd, htdbm
    
        
    Support de l'algorithme bcrypt (disponible à partir de la
	version 2.4.4).

    Documentation
    
    
    
    
        
    mod_rewrite
    
        
    La documentation du module mod_rewrite a
	été réorganisée et presque entièrement réécrite en mettant
	l'accent sur les exemples et l'utilisation courante, ainsi que
	sur l'incitation à utiliser d'autres solutions lorsque cela
	s'avère plus approprié. Le document Rewrite
	Guide constitue maintenant une section de premier niveau ;
	il est mieux organisé et contient beaucoup plus de détails.
    

        
    mod_ssl
    
        
    La documentation du module mod_ssl a été
	grandement améliorée, avec plus d'exemples et un niveau "Bien
	démarrer" qui s'ajoutent aux détails techniques déjà présents
	dans la précédente documentation.
    

        
    Caching Guide
    
        
    Le Guide de la mise en cache a
	été réécrit afin de bien faire la différence entre les
	fonctionnalités de mise en cache de la RFC2616 HTTP/1.1 fournies
	par le module mod_cache, et la mise en cache
	générique de type clé/valeur fournie par l'interface socache, mais aussi pour couvrir la mise
	en cache spécialisée fournie par des mécanismes tels que ceux du
	module mod_file_cache.

    Modifications concernant les développeur de modules
    
    
    
    
      
    Ajout de code pour la vérification de la configuration
    

      
    Une nouvelle fonction, check_config, a été ajoutée et
      s'exécute entre les fonctions pre_config et
      open_logs. Elle s'exécute aussi avant la fonction
      test_config si l'option -t est passée au
      démon httpd. La fonction check_config
      permet aux modules de vérifier l'interdépendance des valeurs des
      directives de configuration et d'ajuster ces valeurs, alors que les
      messages du serveur peuvent encore être affichés sur la console.
      L'utilisateur est ainsi averti des erreurs de configuration avant que la
      fonction du noyau open_logs ne redirige les sorties de la
      console vers le journal des erreurs.
    

      
    Ajout d'un analyseur syntaxique d'expressions
    
      
    Nous disposons à présent d'un analyseur générique d'expressions, dont l'API
      est décrite dans ap_expr.h. Il s'agit d'une adaptation de
      l'analyseur qu'on trouvait auparavant dans mod_ssl.
    

      
    Conteneurs de logique d'autorisation
    

      
    Afin de fournir une logique d'autorisation avancée via des
      directives telles que <RequireAll>, les modules d'autorisation
      s'enregistrent maintenant en tant
      que fournisseur par le biais de ap_register_auth_provider().
    

      
    Interface de mise en cache des petits objets
    

      
    Le fichier d'en-têtes ap_socache.h fournit une
      interface à base de fournisseur pour la mise en cache des petits
      objets de données, en s'inspirant de
      l'implémentation précédente
      du cache de session par mod_ssl. Sont supportés
      actuellement : les fournisseurs utilisant un tampon cyclique en
      mémoire partagée, les fichiers dbm sur disque, et les caches
      distribués de type memcache.
    

      
    Ajout du point d'ancrage Cache Status
    

      
    Le module mod_cache inclut maintenant un
      nouveau point d'ancrage, cache_status, qui est appelé
      lorsque la décision à propos de la mise en cache est connue. Il en
      existe une implémentation par défaut qui ajoute les en-têtes
      optionnels X-Cache et X-Cache-Detail à
      la réponse.
    


    
    
    
    La documentation du développeur contient une liste détaillée des modifications
    de l'API.

    Bir HTTP sunucusunu verimli şekilde yönetebilmek için oluşabilecek
      sorunlardan başka sunucunun başarımı ve etkinliği hakkında da bazı geri
      bildirimler almak gerekir. Apache HTTP Sunucusu çok kapsamlı ve esnek
      bir günlükleme yeteneğine sahiptir. Bu belgede sunucunun günlükleme
      yeteneğini nasıl yapılandıracağınızdan ve günlük kayıtlarını nasıl
      yorumlayacağınızdan bahsedilecektir.

    Giriş
    
    

  
    İlgili Modüllerİlgili Yönergeler
    

  
    Apache HTTP Sunucusu, isteğin ilk alınışından itibaren, URL eşleme
    işlemleri, bağlantının son çözümlemesi ve bu işlemler sırasına ortaya çıkan
    hatalar da dahil olmak üzere sunucunuzda meydana gelen herşeyi günlüklemek
    için çok çeşitli mekanizmalar içerir. Buna ek olarak, günlükleme
    yetenekleri sağlayan üçüncü parti modüller de kullanılabilir veya mevcut
    günlük dosyalarına girdiler enjekte edilebilir. Ayrıca, CGI programları,
    PHP betikleri ve benzerleri sunucu hata günlüğüne kendi iletilerini
    gönderebilirler.
    

  
    Bu belgede Apache HTTP Sunucusunun standart parçası olan günlükleme
    modülleri hakkında bilgi verilecektir.

    Güvenlik Uyarısı
    
    

    
    Apache httpd’nin günlük dosyalarını yazdığı dizine yazabilen birinin sunucuyu
      başlatan kullanıcı kimliğine (bu genellikle root olur) erişim
      kazanabileceğine hemen hemen kesin gözüyle bakılabilir. Sonuçlarının
      neler olacağını kestiremiyorsanız günlüklerin yazıldığı dizinde hiç
      kimseye yazma erişimi vermeyin; ayrıntılı bilgi için güvenlik ipuçları belgesine
      bakınız.
    

    
    Buna ilaveten, günlük dosyaları istemci tarafından sağlanmış bilgiler
      de içerebilir. Bu nedenle, kötü niyetli istemcilerin günlük dosyalarına
      denetim karakterleri girmeleri olasılığına karşı ham günlükler ele
      alınırken dikkatli olunmalıdır.

    Hata Günlüğü
    
    
    
    İlgili Modüllerİlgili Yönergeler
    

    
    İsmi ve yeri ErrorLog yönergesi
      ile belirtilen sunucu hata günlüğü, en önemli günlük dosyasıdır. Apache
      httpd tarafından istekler işlenirken saptanan hatalar ve tanı bilgileri
      bu dosyaya gönderilir. Sunucuyu başlatırken veya sunucu çalışırken bir
      sorunla karşılaşıldığında, neyin yanlış gittiğini öğrenmek için
      bakılacak ilk yer burasıdır. Günlük kaydı çoğunlukla sorunun nasıl
      düzeltileceği ile ilgili ayrıntıları da içerir.
    

    
    Hata günlüğü normal olarak bir dosyaya yazılır (genellikle, dosyanın
      ismi Unix sistemlerinde error_log, OS/2 ve Windows’ta ise
      error.log’dur). Ayrıca, Unix sistemlerinde sunucunun
      hataları syslog’a veya borulamak suretiyle
      bir programa aktarması da mümkündür.
    

    
    Hata günlüğünün biçemi ErrorLogFormat yönergesi ile belirlenir. Bu yönergeyi
      kullanarak günlüklenen değerleri özelleştirebilirsiniz. Bir biçem
      belirtmezseniz öntanımlı biçem kullanılır. Örnek tipik bir hata iletisi
      içermektedir:
    

    
    
    [Fri Sep 09 10:42:29.902022 2011] [core:error] [pid 35708:tid 4328636416]
    [client 72.15.99.187] Dosya yok: /usr/local/apache2/htdocs/favicon.ico
    
    

    
    Günlük girdisinin ilk öğesi iletinin yazıldığı tarih ve saatten oluşur.
      İkincisi iletiyi üreten modülün ismi (bu durumda: core) ile raporlanan
      bilginin önem derecesini belirtir. Bunu varsa sürecin kimliği ve yine
      varsa evre kimliği izler. Sonraki öğe hatanın üretilmesine sebep olan
      istemcinin IP adresini içerir. Kalanı iletinin kendisidir (duruma
      bakılırsa bir dosyaya yapılan istek yerine getirilememiş).
    

    
    Hata günlüğünde görünebilecek ileti çeşitliliği oldukça fazladır. Çoğu
      yukarıdaki örneğin benzeridir. Hata günlüğü ayrıca, CGI betiklerinin
      hata ayıklama çıktılarını da içerir. Bir CGI betiği tarafından standart
      hataya (stderr) yazılan her türlü bilgi doğrudan hata
      günlüğüne kopyalanır.
    

    
    Hata günlüğüne ve erişim günlüğüne  %L dizgeciği konularak
      erişim günlüğündeki girdi ile hata günlüğündeki girdiyi ilişkilendirecek
      bir günlük girdisi kimliği oluşturulabilir.
      mod_unique_id yüklüyse günlük girdisi kimliği olarak
      onun eşsiz istek kimliği de kullanılır.
    

    
    Sunucuyu denerken olası sorunlara karşı hata günlüğünü sürekli
      izlemelisiniz. Unix sistemlerinde bunu şöyle bir komutla
      sağlayabilirsiniz:
    

    
    
      tail -f error_log
    
    
  
    top
    

    

    Modüllere göre günlükleme
    
    

    
    LogLevel yönergesi, günlük
      iletisinin üretilmesine sebep olan modüle bağlı bir önem seviyesi
      belirleyebilmenizi sağlar. Bu yolla sorun yaşadığınız modülle ilgili
      günlük musluklarını sonuna kadar açabiliri ek olarak ilgilendiğiniz diğer
      modüllerle ilgili ayrıntıları da edinebilirsiniz. Özellikle
      mod_proxy veya mod_rewrite gibi
      modüllerde yapılmak isteneni denerken neler olup bittiğini ayrıntılarıyla
      bilmek istediğiniz durumlarda kullanışlıdır.
    

    
    Bunu LogLevel yönergesinde modülün ismini
      belirterek yapabilirsiniz:
    

    
    LogLevel info rewrite:trace5
    


    
    Bu satırla ana LogLevel info'ya ayarlanırken
      mod_rewrite için musluk trace5 seviyesine
      kadar açılmaktadır.
    

    
    Bu yönerge, Apache HTTP Sunucusunun evvelki sürümlerinde mevcut olan
      RewriteLog gibi günlükleme modüllerinin yerini almıştır.
    
    
  
    top
    

    

    Erişim Günlüğü
    
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    Sunucu erişim günlüğü sunucu tarafından işleme alınan tüm istekleri
      kaydeder. Erişim günlüğünün yeri ve içeriği  CustomLog yönergesi ile belirlenir.
      LogFormat yönergesi ile
      günlük içeriğini kişiselleştirmek mümkündür. Bu bölümde sunucunun
      bilgileri erişim günlüğüne kaydetmesi için nasıl yapılandırılacağından
      bahsedilecektir.
    

    
    Şüphesiz, bilginin erişim günlüğünde saklanması günlük yönetiminde ilk
      adımı oluşturur.  Sonraki adım yararlı istatistikleri üretmek için bu
      bilgiyi incelemektir. Günlük incelemesi bu belgenin kapsamına dahil
      değildir ve aslında bu işlem sunucunun yaptığı işlerden biri değildir.
      Bu konu ve günlük incelemesi yapan uygulamalar hakkında daha ayrıntılı
      bilgi edinmek için dmoz.org'a bakınız.
    

    
    Apache httpd’nin çeşitli sürümlerinde erişim günlüklerini denetlemek
      için kullanılan diğer modüller ve yönergeler arasında mod_log_referer,
      mod_log_agent modülleri ve TransferLog yönergesi
      sayılabilir. Artık, daha eski tüm diğer yönergelerin işlevselliklerini
      bir araya toplayan CustomLog yönergesi kullanılmaktadır.
    

    
    Erişim günlüğünün girdi biçemi kolayca isteğe göre
      düzenlenebilmektedir. Biçemi belirtmekte kullanılan biçem dizgesi, C
      tarzı printf(1) biçem dizgesini andırır. Sonraki bölümlerde bazı
      örneklere yer verilmiştir. Biçem dizgesini oluşturan belirteçlerin tam
      listesi için mod_log_config belgesinin Günlük Girdilerinin
      Kişiselleştirilmesi bölümüne bakınız.
    

    
    Ortak Günlük Biçemi (OGB)
    
      

      
    Erişim günlüğü için sıklıkla kullanılan bir yapılandırma:
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog logs/access_log common
    


      
    İlk satırda belli bir biçem dizgesi için common diye bir
        takma ad tanımlanmaktadır. Biçem dizgesi, sunucuya hangi
        belli bir bilgi parçalarını günlükleyeceğini söyleyen % imli biçem
        belirteçlerinden oluşur. Biçem dizgesine ayrıca dizgesel sabitler de
        yerleştirilebilir ve bunlar erişim günlüğüne oldukları gibi
        kopyalanırlar. Biçem dizgesi içinde çift tırnak karakteri (") biçem
        dizgesini vaktinden önce sonlandırmaması için ters bölü çizgisi ile
        öncelenmelidir. Biçem dizgesi ayrıca, satır sonlarını belirtmek için
        "\n" ve sekmeleri belirtmek için "\t"
        denetim karakterlerini de içerebilir.
    

      
    CustomLog yönergesi
        evvelce tanımlanmış bir takma adı kullanarak yeni bir günlük
        dosyası tanımlar. Erişim günlüğünün dosya ismi bölü çizgisi ile
        başlamadıkça dosya yolunun ServerRoot değerine göreli olduğu varsayılır.
    

      
    Yukarıdaki yapılandırma günlük dosyasına girdileri Ortak Günlük
        Biçemi (Common Log Format) adı verilen standart biçemde yazar.
        Bu standart biçem başka HTTP sunucuları tarafından da kullanılır ve
        çoğu günlük inceleme yazılımı tarafından tanınır. Ortak Günlük
        Biçeminde üretilen günlük girdileri şöyle görünür:
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
      
    

      
    Bu günlük girdisini parça parça açıklayalım:
    

      
    
        
    127.0.0.1 (%h)
    

        
    Bu, sunucuya istek yapan istemcinin (uzak konağın) IP adresidir.
          Eğer HostnameLookups
          yönergesine On değeri atanmışsa sunucu bu IP adresi
          için DNS sorgusu yapacak ve IP adresi yerine bulduğu konak ismini
          yazmaya çalışacaktır. Bununla birlikte, bu işlem sunucuyu epeyce
          yavaşlattığından önerilmemektedir. Konak isimlerini saptamak için en
          iyisi günlük girdilerini logresolve gibi bir
          günlük işlemcisinden geçirmektir. Burada raporlanan IP adresi
          doğrudan istemcinin IP adresi olmayabilir. Eğer sunucu ile istemci
          arasında bir vekil sunucu varsa bu IP adresi, vekil sunucunun IP
          adresi olacaktır.
    

        
    - (%l)
    

        
    Çıktıdaki bir "tire" imi istenen bilgi parçasının mevcut olmadığı
          anlamına gelir. Bu durumda, mevcut olmayan bilgi istemci makine
          üzerinde identd tarafından belirlenen istemcinin RFC
          1413 kimliğidir. Bu bilgi oldukça güvenilmezdir ve sıkıca denetlenen
          iç ağlar haricinde hemen hemen asla kullanılmamalıdır. Apache,
          IdentityCheck yönergesine
          On değeri atanmış olmadıkça bu bilgiyi saptamaya
          uğraşmaz.
    

        
    frank (%u)
    

        
    Bu, belge isteğinde bulunan kişinin HTTP kimlik doğrulamasıyla
          saptanan kullanıcı kimliğidir. Bu değer CGI betiklerine
          REMOTE_USER ortam değişkeni ile sağlanır. Eğer istek
          için durum kodu 401 ise (aşağıya bakınız) henüz kullanıcının kimliği
          doğrulanmamış olacağından bu değere güvenilmemelidir. Eğer belge
          parola korumalı değilse günlüğün bu kısmı da yukarıdaki gibi
          "-" olacaktır.
    

        
    [10/Oct/2000:13:55:36 -0700]
        (%t)
    

        
    İsteğin alındığı tarih ve saat. Biçemi şöyledir:

          
    
            [gün/ay/yıl:saat:dakika:saniye dilim]
    
             gün    = 2 hane
    
             ay     = 3 harf
    
             yıl    = 4 hane
    
             saat   = 2 hane
    
             dakika = 2 hane
    
             saniye = 2 hane
    
             dilim  = (`+' | `-') 4 hane    
          
    
          
    Günlük biçem dizgesinde zaman gösterim biçemini
          %{biçem}t şeklinde belirtmek de mümkündür.
          Buradaki biçem dizgesi, stardart C
          kütüphanesindeki strftime(3) işlevi için tanımlanmış
          biçem belirteçleriyle veya desteklenen özel belirteçlerle
          oluşturulabilir. Ayrıntılı bilgi için mod_log_config
          biçem dizgelerine
          bakın.
    
        
    

        
    "GET /apache_pb.gif HTTP/1.0"
        (\"%r\")
    

        
    İstemciden alınan istek satırının çift tırnaklar arasında
          gösterilmesi istenmiştir. İstek satırı en yararlı bilgi parçalarını
          içerir. Birincisi, istemci tarafından kullanılan yöntem
          GET’miş. İkinci olarak istemci
          /apache_pb.gif dosyasını istemiş ve üçüncü olarak
          istemci HTTP/1.0 protokolünü kullanmış. İstek satırının
          bazı parçalarını bağımsız olarak da günlüklemek mümkündür. Örneğin,
          "%m %U%q %H" dizgesi, yöntem, yol, sorgu dizgesi ve
          protokolü kaydedecektir; bu dizge "%r" biçem
          belirtecinin tek başına yaptığı işi yapar.
    

        
    200 (%>s)
    

        
    Bu, sunucunun istemciye gönderdiği durum kodudur. İsteğin
          başarıyla yerine getirilip getirilmediğini gösterdiği için bu bilgi
          çok değerlidir. Durum kodu 2 ile başlıyorsa istek başarıyla yerine
          getirilmiştir, 3 ile başlıyorsa yönlendirilmiştir, 4 ile başlıyorsa
          istemci tarafında bir hata oluşmuştur, 5 ile başlıyorsa sunucuda bir
          hata oluşmuştur. Olası hata kodlarının tam listesi RFC2616 Hiper
          Metin Aktarım Protokolünün 10. bölümünde bulunabilir.
    

        
    2326 (%b)
    

        
    Son parça istemciye döndürülen nesnenin yanıt başlığı hariç
          uzunluğudur. Eğer istemciye bir içerik döndürülmemişse bu değer
          "-" olacaktır. Bunun yerine günlüğe "0"
          yazdırmak için %B belirtecini kullanınız.
    
      
    
    

    
    Birleşik Günlük Biçemi
    
      

      
    Sıklıkla kullanılan diğer bir biçem dizgesi Birleşik Günlük Biçemi
        (Combined Log Format) olup şöyle kullanılabilir:
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined

    Bu biçem ilaveten 2 alan içermesi dışında Ortak Günlük Biçemi ile
        aynıdır. İlave alanların ikisi de %{başlık}i
        biçeminde olup buradaki başlık, HTTP isteğindeki
        başlık alanlarından biridir. Bu biçemin kullanıldığı bir erişim
        günlüğü girdisi şöyle olurdu:
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
        "http://www.example.com/start.html" "Mozilla/4.08 [en]
        (Win98; I ;Nav)"
      
    

      
    Ek alanlar:
    

      
    
        
    "http://www.example.com/start.html"
        (\"%{Referer}i\")
    

        
    HTTP istek başlığı "Referer". İstemcinin raporladığı isteğin
          kaynaklandığı URI. (Bu isteğin yapılmasını sağlayan bağlantıyı
          içeren URL veya istek bir sayfanın bileşenleri ile ilgiliyse istenen
          sayfanın URL’si olabilir.)
    

        
    "Mozilla/4.08 [en] (Win98; I ;Nav)"
        (\"%{User-agent}i\")
    

        
    Tarayıcı kimliğini içeren HTTP istek başlığı. Bu istemcinin
          tarayıcısının raporladığı kendi tanıtım bilgisidir.
    
      
    
    

    
    Çok Sayıda Erişim Günlüğü
    
      

      
    Yapılandırma dosyasında çok sayıda CustomLog yönergesi kullanarak çok
        sayıda erişim günlüğü kolayca oluşturulabilir. Örneğin aşağıdaki
        yönergelerle 3 tane erişim günlüğü oluşturulacaktır. İlki temel OGB
        bilgisini içerirken diğer ikisi isteğin kaynaklandığı yeri ve tarayıcı
        kimliğini içerir. Son iki CustomLog satırı ayrıca, ReferLog ve
        AgentLog yönergelerinin etkilerinin nasıl taklit
        edileceğini de göstermektedir.
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog logs/access_log common
CustomLog logs/referer_log "%{Referer}i -> %U"
CustomLog logs/agent_log "%{User-agent}i"
    


      
    Bu örnek ayrıca, LogFormat yönergesi ile bir takma ad tanımlamanın şart
        olmadığını da göstermektedir. Günlük biçemi doğrudan CustomLog yönergesinde
        belirtilebilir.
    
    

    
    Şarta Bağlı Günlükler
    
      

      
    Bazı durumlarda istemcinin yaptığı isteğe bağlı olarak erişim
        günlüğünde belli girdilerin dışlanması gerekebilir. Bu, ortam değişkenleri sayesinde kolayca yerine
        getirilebilir. Önce isteğin belli koşulları sağladığını belirten bir
        ortam değişkeni ataması yapılır. Bu işlem SetEnvIf yönergesi ile yapılır.
        Sonra da, ortam değişkenine bağlı olarak isteklerin günlüğe dahil
        edilip edilmeyeceği CustomLog yönergesinin
        env= deyimi kullanılarak belirtilir. Bazı örnekler:
    

      
    # yerel konaktan kaynaklanan istekleri imleyelim
SetEnvIf Remote_Addr "127\.0\.0\.1" kaydetme
# robots.txt dosyası isteklerini imleyelim
SetEnvIf Request_URI "^/robots\.txt$" kaydetme
# Kalanları günlüğe kaydedelim
CustomLog logs/access_log common env=!kaydetme
    


      
    Başka bir örnek olarak, Türkçe belge isteklerini bir dosyaya diğer
        dillerdeki istekleri başka bir dosyaya kaydedelim.
    

      
    SetEnvIf Accept-Language "tr" turkce
CustomLog logs/turkce_log common env=turkce
CustomLog logs/diger_diller_log common env=!turkce
    


      
    Bir arabellekleme senaryosuna arabelleğin verimli kullanılıp
        kullanılmadığını bilmek isteyelim. Bu basitçe şöyle yapılabilir:
    

      
    SetEnv CACHE_MISS 1
LogFormat "%h %l %u %t "%r " %>s %b %{CACHE_MISS}e" common-cache
CustomLog logs/access_log common-cache
    


      
    mod_cache önce mod_env modülünü
        çalıştıracak ve başarılı olunduğu takdirde içeriği onsuz teslim
        edecektir. Bu durumda arabellek kaybı 1 olarak
        günlüklenirken arabellek sunumu - olarak
        günlüklenecektir.
    

      
    env= sözdizimine ek olarak, LogFormat HTTP yanıt kodudaki koşul
        değerlerini günlüklemeyi de destekler:
    

      
    LogFormat "%400,501{User-agent}i" browserlog
LogFormat "%!200,304,302{Referer}i" refererlog
    


      
    Bu örnekte, HTTP durum kodu 400 veya 501 ise User-agent
        başlığı günlüklenecektir. Aksi takdirde, günlüğe bir "-" yazılacaktır.
        Benzer şekilde ikinci örnekte, HTTP durum kodu 200, 204 veya 302
        değilse (durum kodlarının öncesindeki "!" imine
        dikkat) Referer başlığı günlüklenecektir.
    

      
    Koşula bağlı günlük kaydının çok esnek ve güçlü olabileceğini
        göstermiş olsak da günlük içeriğini denetlemenin tek yolu bu değildir.
        Günlük dosyaları sunucu etkinliğini eksiksiz olarak kaydedebildikleri
        takdirde daha yararlı olurlar. Günlük dosyalarını sonradan işleme tabi
        tutarak istenmeyen girdileri kaldırılmış bir kopya almak hem kolay hem
        de daha yararlıdır.
    
    
  
    top
    

    

    Günlük Çevrimi
    
    

    
    Yükü ağır sunucularda günlük dosyalarına kaydedilen bilginin miktarı
      çok büyük boyutlara ulaşabilir. 10.000 istek içeren bir erişim günlüğü
      yaklaşık 1MB yer kaplar. Etkin günlük dosyasını belirli aralıklarla
      değiştirmek veya silmek gerekebilir. Apache httpd çalışırken dosyayı sürekli
      açık tuttuğu ve yazdığı için bu işlem sunucu çalışırken yapılamaz. Bu
      bakımdan, günlük dosyası değiştirildikten veya silindikten sonra yeni
      dosyanın açılması için sunucunun yeniden
      başlatılması gerekir.
    

    
    Nazikçe yeniden başlatmak
      suretiyle sunucunun, mevcut ve bekleyen bağlantıları kaybetmeden yeni
      günlük dosyalarını açması sağlanabilir. Bununla birlikte, bu işlem
      sırasında sunucunun eski isteklere sunumu bitirene kadar eski günlük
      dosyalarına yazmaya devam edebilmesi gerekir. Bu bakımdan, yeniden
      başlatmanın ardından eski günlük dosyaları üzerinde bir işlem yapmadan
      önce biraz beklemek gerekir. Günlük dosyalarını döndürürken kullanılan
      senaryolarda genellikle eski günlük dosyaları yer kazanmak için
      sıkıştırılırlar:
    

    
    
      mv access_log access_log.old
    
      mv error_log error_log.old
    
      apachectl graceful
    
      sleep 600
    
      gzip access_log.old error_log.old
    
    

    
    Günlük çevrimi yapmanın başka bir yolu da sonraki bölümde açıklandığı
      gibi borulu günlükler kullanmaktır.
    
  
    top
    

    

    Borulu Günlükler
    
    

    
    Apache httpd hata ve erişim günlüklerini doğrudan bir dosyaya yazmak
      yerine bir boru üzerinden başka bir sürece yazabilir. Bu yetenek ana
      sunucuya herhangi bir kod eklemeksizin günlükleme esnekliğini şaşırtıcı
      derecede arttırır. Günlükler boruya yazılmak istenirse dosya ismini boru
      karakteriyle ("|") değiştirip ardına günlük girdilerini
      standart girdisinden kabul edecek programın ismini eklemek yeterlidir.
      Apache httpd başlatıldığı zaman borulu günlük işlemini de
      başlatacaktır. Eğer sunucu çalışırken günlükleri kabul eden süreç
      çökerse Apache httpd bu programı yeniden başlatır. (Bu son özelliği
      sebebiyle bu tekniğe “güvenilir borulu günlükleme” adını veriyoruz.)
    

    
    Borulu günlük süreçleri ana Apache httpd süreci tarafından başlatılır
      ve bu süreçler ana Apache httpd sürecinin kullanıcı kimliğini miras
      alırlar. Yani borulu günlükleme programları aslında root tarafından
      çalıştırılmış gibi olur. Bu bakımdan, bu programları basit ve güvenilir
      kılmak çok önemlidir.
    

    
    Borulu günlüklerin önemli kullanım alanlarından biri de sunucuyu
      yeniden başlatmak gerekmeksizin günlük çevrimini mümkün kılmaktır.
      Apache HTTP sunucusu bu amaçla kullanılmak üzere
      rotatelogs diye bir program içerir. Örneğin,
      günlükleri 24 saatte bir döndürmek isterseniz bunu şöyle
      yapabilirsiniz:
    

    
    CustomLog "|/usr/local/apache/bin/rotatelogs /var/log/access_log 86400" common
    


    
    Borunun diğer ucundaki süreci başlatacak komutun tırnak içine
      alındığına dikkat ediniz. Bu örnekler erişim günlüğü için verilmişse de
      aynı teknik hata günlüğü için de kullanılabilir.
    

    
    Hariçten bir uygulama olarak cronolog isminde buna benzer ancak
      çok daha esnek bir program daha vardır.
    

    
    Borulu günlükler de şarta bağlı günlükleme kadar güçlü olmakla beraber
      çevrimdışı ardıl işlemler gibi daha basit çözümler için
      kullanılmamalıdır.
    

    
    Öntanımlı olarak borulu günlük süreci bir kabuk kullanmadan
      çalıştırılır. Kabuk kullanarak (genelde /bin/sh -c ile)
      yapılmak istenirse "|" yerine "|$"
      kullanılır:
    

    
    # Kabuk kullanarak "rotatelogs" çalıştırmak
CustomLog "|$/usr/local/apache/bin/rotatelogs /var/log/access_log 86400" common
    


    
    Bu, Apache 2.2 için öntanımlı davranıştı. Kabuk özelliklerine bağlı
      olarak, yeniden başlatma sırasındaki sinyal işleme sorunları ve günlük
      borulama uygulamasının yaşam süresi için ek bir kabuk süreci ile
      sonuçlanabilir. Apache 2.2 ile uyumluluk açısından "||"
      gösterimi de desteklenmekte olup "|" kullanımına
      eşdeğerdir.
    

    
    Windows'ta yığın alanı
    
    
    Windows'ta çok sayıda borulu günlükleme süreci çalışırken ve özellikle
      HTTPD bir hizmet olarak çalışıyorsa sorunlar baş gösterebilir. Bunun
      başlıca sebebi masaüstü yığın alanının (heap) dışına taşılmasıdır. Her
      hizmete ayrılan masüstü yığın alanı, kayıt defterindeki
      HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\SubSystems\Windows
      kaydındaki üçüncü değiştirge olan SharedSection
      değeridir. Bu değeri değiştirirken çok dikkatli olun;
      bu, Windows kayıt defterini değiştirirken verilen normal
      uyarılardandır, fakat eğer bu değer çok yüksek olursa masaüstü yığın
      alanının tükenebileceği dikkate alınmalıdır.
    
    
    
  
    top
    

    

    Sanal Konaklar
    
    

    
    Bir sunucu çok sayıda sanal konak ile hizmet
      sunarken bunların günlük kayıtları için çeşitli seçenekler mevcuttur.
      İlk seçenekte, sanki sunucu tek bir konakla hizmet sunuyormuş gibi
      günlük kaydı yapılır. Günlükleme yönergelerini <VirtualHost> bölümlerinin dışına, ana sunucu
      bağlamına yerleştirerek tüm isteklerin aynı erişim ve hata günlüğüne
      yazılmasını sağlamak olasıdır. Bu teknik, tek tek sanal konaklar için
      kolayca istatistik toplamaya izin vermez.
    

    
    Eğer  CustomLog
      veya ErrorLog yönergesi bir
      <VirtualHost> bölümüne
      yerleştirilirse bu sanal konağa bütün erişimler veya hatalar belirtilen
      dosyaya günlüklenecektir. Böyle günlükleme yönergeleri içermeyen sanal
      konakların günlükleri hala ana sunucunun hata ve erişim günlüklerine
      yazılmaya devam edecektir. Bu teknik az sayıda sanal konak barındıran
      sunucular için çok kullanışlıdır. Fakat sanal konak sayısı çok fazlaysa
      bu teknikle günlük dosyalarını yönetmek çok karmaşık bir hal alabilir.
      Ayrıca, yetersiz dosya tanıtıcısı
      sorunlarıyla çok sık karşılaşılabilir.
    

    
    Erişim günlükleri için çok az bir fedakarlıkla çok iyi bir çözüm vardır.
      Günlük biçemine sanal konaklarla ilgili bilgi eklemek suretiyle tüm
      konakların aynı günlük dosyasını kullanmaları olasıdır. Böylece günlük
      dosyası sonradan her sanal konak için ayrı bir dosya oluşturmak üzere
      ayrıştırılabilir. Örneğin, bu işlem için şu yönergeler kullanılıyor
      olsun:
    

    
    LogFormat "%v %l %u %t \"%r\" %>s %b" ortaksankon
CustomLog logs/access_log ortaksankon
    


    
    %v belirteci isteği sunan sanal konağın ismini günlüğe
      yazmak için kullanılır. Daha sonra split-logfile gibi bir program
      kullanarak, bu dosyadan her sanal konak için ayrı birer dosya elde
      edilebilir.
    
  
    top
    

    

    Diğer Günlük Dosyaları
    
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    Gönderilen ve alınan bayt sayısının günlüklenmesi
    
      

      
    mod_logio modülü LogFormat yönergesinde kullanılan
        biçem belirteçlerine alınan ve gönderilen bayt sayıları için iki
        belirteç (%I ve %O) ekler.
    
    

    
    Adli Günlük
    
      

      
    mod_log_forensic modülü istemci isteklerinin kanıt
        olarak kullanılmak amacıyla günlüklenmesini sağlar. Günlükleme her
        istek için isteğe hizmet sunmadan önce ve sonra olmak üzere iki defa
        yapılır. Böylece günlük dosyasında başarılı her istek için iki satır
        bulunur. Adli günlükleme çok sıkı kurallara tabi olup
        kişiselleştirilemez. Güvenlik ve hata ayıklama aracı olarak yararlı
        değildir.
    
    

    
    PID Dosyası
    
      

      
    Apache httpd başlatıldığında, ana httpd sürecinin kimliği (PID)
        logs/httpd.pid dosyasına kaydedilir. Bu dosyanın ismi
        PidFile yönergesi ile
        değiştirilebilir. Bu süreç kimliği sistem yöneticisi tarafından ana
        sürece sinyal göndererek artalan sürecini sonlandırmak veya yeniden
        başlatmak için kullanılır. Windows üzerinde bu işlem için
        -k komut satırı seçeneği kullanılır. Bu konuda daha
        ayrıntılı bilgi edinmek için Durdurma ve
        Yeniden Başlatma belgesine bakınız.
    
    

    
    Betik Günlüğü
    
      

      
    ScriptLog yönergesi CGI
        betiklerinin girdi ve çıktılarını kaydetmenizi mümkün kılmak suretiyle
        hata ayıklamaya yardımcı olur. Bu sadece deneysel amaçla kullanılmalı,
        asıl sunucuya uygulanmamalıdır. mod_cgi
        belgesinde daha fazla bilgi bulunabilir.

    NN は最新のバージョンナンバーに、
    PREFIX はインストールするサーバでのファイルシステムのパスに、
    置き換えてください。PREFIX を指定しなかった場合は、
    デフォルトの /usr/local/apache2 になります。
    

    
    Apache httpd のコンパイルとインストールに必要なものをはじめとして、
    コンパイルとインストールについては、次に詳しく記述されています。
    

    top
    

    

    必要なもの
    

    
    Apache のビルドには次のものが必要です:
    

    
    
      
    ディスクスペース
    
      
    ディスクに少なくとも 50 MB の一時的な空き容量があるように
      気を付けてください。インストール後は Apache は 10 MB 程度の
      ディスクスペースを占めます。実際に必要になるディスクスペースは、
      設定オプションやサードパーティー製モジュールをどう選択するかによって
      大きく変わるでしょう。
    

      
    ANSI-C コンパイラとビルドシステム
    
      
    ANSI-C コンパイラをインストールしておいて下さい。お薦めは Free Software Foundation (FSF)
      による GNU C
      compiler (GCC) です。GCC がない場合は、
      少なくとも提供されているコンパイラが ANSI 準拠であることを確認しておいて下さい。
      それから、変数 PATH には make
      といった基本的なビルドツールが含まれている必要があります。
    

      
    時刻を正確にする
    
      
    HTTP プロトコルの要素は日時の時刻で表現されています。ですから、
      正確な時刻にシンクロさせる機能をシステムに設定することを吟味してみて下さい。
      Network Time Protocol (NTP) をベースとした ntpdate や xntpd プログラムが
      この目的によく用いられます。NTP ソフトウェアや公開 NTP 
      サーバに関する詳細は、NTP ホームページ をご覧下さい。
    

      
    Perl 5
      [オプション]
    
      
    提供されているスクリプト幾つか、例えば apxs や
      dbmmanage は
      Perl で書かれているので、Perl 
      5 インタプリタが必要になります (5.003 以降)。
      Perl インタプリタを複数インストールしている (たとえば全体のシステムの一部
      としてインストールされている Perl 4 と、自分で追加でインストールした
      Perl 5 があるなどの) 場合、--with-perl オプション (下記参照)
      を使って configure が意図したものを使うように
      明示的に指定すると良いでしょう。
      configure スクリプトで Perl 5 インタプリタが
      見つからない場合は、この影響を受けるサポートスクリプトが使えなくなります。
      もちろん、Apache httpd のコンパイルとインストールは問題なく行えます。

    ダウンロード
    

    
    Apache HTTP サーバは Apache HTTP
    サーバダウンロードサイトからダウンロードできますし、
    同じ場所に幾つかのミラーサイトもリストしています。
    UNIX に類似するシステムで Apache を使うユーザは、ソースを
    ダウンロードしてビルドしたほうが良いでしょう。
    ビルドの手順（下記）は簡単ですし、そのおかげでニーズに
    見合ったカスタマイズを簡単にできます。
    さらに、バイナリのリリースはソースリリースよりも
    遅れていることがよくあります。
    それでもバイナリをダウンロードしたのであれば、
    ディストリビューションの中にある INSSTALL.bindist 
    ファイルの説明に従ってください。
    

    
    ダウンロード後、ダウンロードしたものが Apache HTTP 
    サーバの完全で改竄されていないバージョンであることを
    検証することが重要です。これはダウンロードした tarball の PGP 署名を
    テストすることによって検証します。
    この手順の詳細は ダウンロード
    ページ にあり、さらに詳しい例は PGP の使用
     に記載されています。
    


    top
    

    

    展開
    

    
    Apache HTTPD の tarball
    からソースファイルを展開して取り出すとは、
    単なる圧縮の解除と tar の展開です:
    


    
$ gzip -d httpd-NN.tar.gz
    
$ tar xvf httpd-NN.tar

    

    
    配布用のソースコードがある現在いるディレクトリの下に、
    新しいディレクトリが作られます。

    cd で移動してください。

    ソースツリーを設定する
    

    
    次のステップは、あなたのプラットホームと
    個人的な要求に合うように Apache
    ソースツリーを設定することです。
    これは配布ディレクトリのルートディレクトリにある、
    configure
    スクリプトで行ないます。
     (Apache ソースツリーの未リリース
    版をダウンロードした開発者は、次のステップに進む前に
    autoconf とlibtool
    をインストールして buildconf
    を実行する必要があります。
    公式リリースではこの作業は必要ありません。) 
    

    
    デフォルトオプションを使ってソースツリーを全て設定する
    のであれば、単純に ./configure とタイプしてください。
    デフォルトオプションを変更できるように、configure
    には様々な変数やコマンドラインオプションが用意されています。
    

    
    最も重要なオプションは、Apache がこの後でインストールされる位置
    --prefix です。Apache は、このインストール位置に
    おいて正常に動作するように設定しなければならないからです。
    さらに詳細なファイル位置の制御は追加の 設定オプション
     でできます。
    

    
    この時点で、モジュール を有効にしたり
    無効にしたりすることで Apache 本体に含まれる 機能
    を指定できます。Apache 本体にはデフォルトで、モジュールの Base セットが
    含まれます。その他のモジュールは 
    --enable-module オプションで
    有効になります。ここで module はモジュールの名前で、
    つまりそれはモジュールの名前から mod_ 文字列を取り除いた後に
    アンダースコアをダッシュで置換した文字列です。
    これとは別の方法で --enable-module=shared
    オプションを使って、モジュールを
    シェアードオブジェクト (DSO) -- 実行時にロードしたり
    アンロードしたりできる形式 -- としてコンパイルすることもできます。
    同様に、--disable-module オプションで
    Base モジュールを無効化することもできます。
    これらのオプションを使っているときに、もし指定したモジュールが存在しなくても
    configure は警告を上げることなく、単純にオプションを
    無視することに気をつけてください。
    

    
    上記に加えて、configure スクリプトに、
    コンパイラ、ライブラリ、ヘッダファイルの位置を追加情報として渡す
    必要がある場合があります。このような場合には、環境変数あるいは
    コマンドラインオプションで configure に渡します。
    詳細に関しては configure マニュアルページ
    をご覧ください。あるいは --help オプションつきで
    configure を呼び出してください。
    

    
    ちょっとどんなことができるかを見せましょう。
    ここで典型的な例として、/sw/pkg/apache 
    というインストールツリーでコンパイラとフラグを指定して、
    さらに二つの追加モジュール mod_rewrite と
    mod_speling を後で DSO 
    メカニズムでロードするようにコンパイルしてみます:
    


    
      $ CC="pgcc" CFLAGS="-O2" \
    
       ./configure --prefix=/sw/pkg/apache \
    
       --enable-rewrite=shared \
    
       --enable-speling=shared

    

    
    configure を実行したら、システムの機能を
    テストしたり、後でサーバをコンパイルするために必要な Makefile
    を生成したりするのに数分間かかるでしょう。
    

    
    個々の configure オプションの詳細に関しては
    configure マニュアルページ
    をご覧ください。
    

    top
    

    

    ビルド
    

    
    これで Apache の様々なパーツをビルドすることができます。
    次のコマンドを単純に実行するだけです:
    


    $ make
    

    
    基本的な設定をするのに数分かかりますが、
    あらかじめご了承ください。
    また、時間はハードウェアや有効にしたモジュールの数に
    大きく依存するでしょう。
    

    top
    

    

    インストール
    

    
    さて、設定したインストール PREFIX 
     (前述の --prefix オプションを参照) 
    以下にパッケージをインストールする段階になりました。
    次のコマンドを実行してください:
    


    $ make install
    

    
    通常 PREFIX は書き込みパーミッションが制限されている
    ディレクトリになっているので、このステップは通常は
    ルート権限が必要です。
    

    
    アップグレードする場合は、インストールでは設定ファイルや
    ドキュメントファイルの上書きは行いません。
    

    top
    

    

    カスタマイズ
    

    
    次に PREFIX/conf/ 以下にある 設定ファイルを編集して、
    Apache HTTP サーバをカスタマイズします。
    


    $ vi PREFIX/conf/httpd.conf
    

    
    PREFIX/docs/manual/ や
    docs/manual/ にある Apache マニュアルをざっと見てください。
    または、http://httpd.apache.org/docs/2.4/
    にあるマニュアル最新版、設定ディレクティブに当たってみてください。
    

    top
    

    

    テスト
    

    
    次のコマンドを実行して Apache HTTP サーバを開始できます:
    


    $ PREFIX/bin/apachectl -k start
    

    
    URL http://localhost/ を通して最初のドキュメントに対する
    リクエストを発行する事ができるはずです。これで見える
    ウェブページは DocumentRoot
    以下に置かれたもので、通常は
    PREFIX/htdocs/ でしょう。
    サーバを再び停止するには、
    次のコマンドを実行します:
    


    $ PREFIX/bin/apachectl -k stop
    

    top
    

    

    アップグレード
    

    
    アップグレードでまず行なうべきことは、リリースアナウンスと
    ソースディストリビューションに入っている CHANGES を読んで、
    自身のサイトに対して影響を及ぼす変更点を探すことです。
    メジャーリリース間の変更をする場合 (例えば 1.3 から 2.0 へ、2.0 から 2.2 へ)
    は、コンパイル時や実行時の設定に大きな差異があるでしょうから、
    手動の調整が必要になるでしょう。モジュールも全て、API
    の変更に合わせるためにアップグレードが必要になるでしょう。
    

    
    マイナーバージョンから次のバージョンにアップグレードする場合
    (例えば 2.2.55 から 2.2.57 へ) は、もっと簡単です。
    make install を実行しても今あるドキュメント、
    ログファイル、設定ファイルは上書きされません。
    さらに、マイナーバージョン間では configure オプション、
    実行時の設定、モジュール API に不整合が起こらないように、
    開発者は最大限の努力をしています。
    大抵の場合、同一の configure コマンドライン、
    同一の設定ファイル、モジュール全てが正常に動作するはずです。
    

    
    マイナーバージョンでアップグレードする場合は、
    既にインストールされているサーバの build ディレクトリ内か、
    以前インストールに使ったソースコードツリーの最上位ディレクトリ内にある、
    config.nice ファイルを探してください。
    このファイルにはソースツリーを設定した時に使った
    configure コマンドラインが、そのまま入っています。
    次のバージョンにアップグレードする場合は config.nice
    ファイルを新しいバージョンのソースツリーにコピーし、
    必要であればそれを編集した後に、次のように実行します。
    

    
    
    $ ./config.nice
    
    $ make
    
    $ make install
    
    $ PREFIX/bin/apachectl -k graceful-stop
    
    $ PREFIX/bin/apachectl -k start
    
    
    

    
    新しいバージョンを使用する場合は、
    実際に運用を始める前に、必ず自分用の環境でテストすべきです。
    最終的にアップグレードする前に、非互換性がないかをテストするために、
    例えば、異なる --prefix と異なるポート (Listen ディレクティブで設定します) 
    を使用することで、古いバージョンに影響を与えずに新しいバージョンを
    インストールし、実行できます。
    

    
    もとの configure に追加する形で、
    追加の引数を config.nice に渡すこともできます:
    

    
    
    $ ./config.nice --prefix=/home/test/apache --with-port=90

    Directives in the configuration files may apply to the
entire server, or they may be restricted to apply only to particular
directories, files, hosts, or URLs.  This document describes how to
use configuration section containers or .htaccess files
to change the scope of other configuration directives.

    Types of Configuration Section Containers
    


    Related ModulesRelated Directives
    


    There are two basic types of containers.  Most containers are
evaluated for each request.  The enclosed directives are applied only
for those requests that match the containers.  The <IfDefine>, <IfModule>, and
<IfVersion>
containers, on the other hand, are evaluated only at server startup
and restart.  If their conditions are true at startup, then the
enclosed directives will apply to all requests.  If the conditions are
not true, the enclosed directives will be ignored.
    


    The <IfDefine> directive
encloses directives that will only be applied if an appropriate
parameter is defined on the httpd command line.  For example,
with the following configuration, all requests will be redirected
to another site only if the server is started using
httpd -DClosedForNow:
    


    <IfDefine ClosedForNow>
    Redirect "/" "http://otherserver.example.com/"
</IfDefine>
    



    The <IfModule>
directive is very similar, except it encloses directives that will
only be applied if a particular module is available in the server.
The module must either be statically compiled in the server, or it
must be dynamically compiled and its LoadModule line must be earlier in the
configuration file.  This directive should only be used if you need
your configuration file to work whether or not certain modules are
installed.  It should not be used to enclose directives that you want
to work all the time, because it can suppress useful error messages
about missing modules.
    


    In the following example, the MimeMagicFile directive will be
applied only if mod_mime_magic is available.
    


    <IfModule mod_mime_magic.c>
    MimeMagicFile "conf/magic"
</IfModule>
    



    The <IfVersion>
directive is very similar to <IfDefine> and <IfModule>, except it encloses directives that will
only be applied if a particular version of the server is executing.  This
module is designed for the use in test suites and large networks which have to
deal with different httpd versions and different configurations.
    


    <IfVersion >= 2.4>
    # this happens only in versions greater or
    # equal 2.4.0.
</IfVersion>
    



    <IfDefine>,
<IfModule>, and the
<IfVersion>
can apply negative conditions by preceding their test with "!".
Also, these sections can be nested to achieve more complex
restrictions.

    Filesystem, Webspace, and Boolean Expressions
    


    The most commonly used configuration section containers are the
ones that change the configuration of particular places in the
filesystem or webspace.  First, it is important to understand the
difference between the two.  The filesystem is the view of your disks
as seen by your operating system.  For example, in a default install,
Apache httpd resides at /usr/local/apache2 in the Unix
filesystem or "c:/Program Files/Apache Group/Apache2" in
the Windows filesystem.  (Note that forward slashes should always be
used as the path separator in Apache httpd configuration files, even for Windows.)  In contrast,
the webspace is the view of your site as delivered by the web server
and seen by the client.  So the path /dir/ in the
webspace corresponds to the path
/usr/local/apache2/htdocs/dir/ in the filesystem of a
default Apache httpd install on Unix.  The webspace need not map directly to
the filesystem, since webpages may be generated dynamically
from databases or other locations.
    


    Filesystem Containers
    


    The <Directory>
and <Files>
directives, along with their regex
counterparts, apply directives to
parts of the filesystem.  Directives enclosed in a <Directory> section apply to
the named filesystem directory and all subdirectories of that
directory (as well as the files in those directories).
The same effect can be obtained using .htaccess files.  For example, in the
following configuration, directory indexes will be enabled for the
/var/web/dir1 directory and all subdirectories.
    


    <Directory "/var/web/dir1">
    Options +Indexes
</Directory>
    



    Directives enclosed in a <Files> section apply to any file with
the specified name, regardless of what directory it lies in.
So for example, the following configuration directives will,
when placed in the main section of the configuration file,
deny access to any file named private.html regardless
of where it is found.
    


    <Files "private.html">
    Require all denied
</Files>
    



    To address files found in a particular part of the filesystem, the
<Files> and
<Directory> sections
can be combined.  For example, the following configuration will deny
access to /var/web/dir1/private.html,
/var/web/dir1/subdir2/private.html,
/var/web/dir1/subdir3/private.html, and any other instance
of private.html found under the /var/web/dir1/
directory.
    


    <Directory "/var/web/dir1">
    <Files "private.html">
        Require all denied
    </Files>
</Directory>
    




    Webspace Containers
    


    The <Location>
directive and its regex counterpart, on
the other hand, change the
configuration for content in the webspace.  For example, the following
configuration prevents access to any URL-path that begins in /private.
In particular, it will apply to requests for
http://yoursite.example.com/private,
http://yoursite.example.com/private123, and
http://yoursite.example.com/private/dir/file.html as well
as any other requests starting with the /private string.
    


    <LocationMatch "^/private">
    Require all denied
</LocationMatch>
    



    The <Location>
directive need not have anything to do with the filesystem.
For example, the following example shows how to map a particular
URL to an internal Apache HTTP Server handler provided by mod_status.
No file called server-status needs to exist in the
filesystem.
    


    <Location "/server-status">
    SetHandler server-status
</Location>
    




    Overlapping Webspace
    

    In order to have two overlapping URLs one has to consider the order in which
certain sections or directives are evaluated. For
<Location> this would be:
    

    <Location "/foo">
</Location>
<Location "/foo/bar">
</Location>
    


    <Alias>es on the other hand,
are mapped vice-versa:
    

    Alias "/foo/bar" "/srv/www/uncommon/bar"
Alias "/foo"     "/srv/www/common/foo"
    


    The same is true for the ProxyPass
directives:
    

    ProxyPass "/special-area" "http://special.example.com" smax=5 max=10
ProxyPass "/" "balancer://mycluster/" stickysession=JSESSIONID|jsessionid nofailover=On
    




    Wildcards and Regular Expressions
    


    The <Directory>,
<Files>, and
<Location>
directives can each use shell-style wildcard characters as in
fnmatch from the C standard library.  The character "*"
matches any sequence of characters, "?" matches any single character,
and "[seq]" matches any character in seq.  The "/"
character will not be matched by any wildcard; it must be specified
explicitly.
    


    If even more flexible matching is required, each
container has a regular expression (regex) counterpart <DirectoryMatch>, <FilesMatch>, and <LocationMatch> that allow
perl-compatible
regular expressions
to be used in choosing the matches.  But see the section below on
configuration merging to find out how using regex sections will change
how directives are applied.
    


    A non-regex wildcard section that changes the configuration of
all user directories could look as follows:
    


    <Directory "/home/*/public_html">
    Options Indexes
</Directory>
    



    Using regex sections, we can deny access to many types of image files
at once:
    

    <FilesMatch "\.(?i:gif|jpe?g|png)$">
    Require all denied
</FilesMatch>
    



    Regular expressions containing named groups and
backreferences are added to the environment with the
corresponding name in uppercase. This allows elements of filename paths
and URLs to be referenced from within expressions
and modules like mod_rewrite.
    


    <DirectoryMatch "^/var/www/combined/(?<SITENAME>[^/]+)">
    Require ldap-group "cn=%{env:MATCH_SITENAME},ou=combined,o=Example"
</DirectoryMatch>
    





    Boolean expressions
    

    The <If>
directive change the configuration depending on a condition which can be
expressed by a boolean expression. For example, the following configuration
denies access if the HTTP Referer header does not start with
"http://www.example.com/".
    

    <If "!(%{HTTP_REFERER} -strmatch 'http://www.example.com/*')">
    Require all denied
</If>
    





    What to use When
    


    Choosing between filesystem containers and webspace containers is
actually quite easy.  When applying directives to objects that reside
in the filesystem always use <Directory> or <Files>.  When applying directives to objects
that do not reside in the filesystem (such as a webpage generated from
a database), use <Location>.
    


    It is important to never use <Location> when trying to restrict
access to objects in the filesystem.  This is because many
different webspace locations (URLs) could map to the same filesystem
location, allowing your restrictions to be circumvented.
For example, consider the following configuration:
    


    <Location "/dir/">
    Require all denied
</Location>
    



    This works fine if the request is for
http://yoursite.example.com/dir/.  But what if you are on
a case-insensitive filesystem?  Then your restriction could be easily
circumvented by requesting
http://yoursite.example.com/DIR/.  The <Directory> directive, in
contrast, will apply to any content served from that location,
regardless of how it is called.  (An exception is filesystem links.
The same directory can be placed in more than one part of the
filesystem using symbolic links.  The <Directory> directive will follow the symbolic
link without resetting the pathname.  Therefore, for the highest level
of security, symbolic links should be disabled with the appropriate
Options directive.)
    


    If you are, perhaps, thinking that none of this applies to you
because you use a case-sensitive filesystem, remember that there are
many other ways to map multiple webspace locations to the same
filesystem location.  Therefore you should always use the filesystem
containers when you can.  There is, however, one exception to this
rule.  Putting configuration restrictions in a <Location
"/"> section is perfectly safe because this section will apply
to all requests regardless of the specific URL.
    



    Nesting of sections
    


    Some section types can be nested inside other section types. On the one
hand, <Files> can be used
inside <Directory>.  On
the other hand, <If> can
be used inside <Directory>,
<Location>, and <Files> sections (but not inside another
<If>). The regex
counterparts of the named section behave identically.
    


    Nested sections are merged after non-nested sections of the same type.
    




    top
    

    

    Virtual Hosts
    


    The <VirtualHost>
container encloses directives that apply to specific hosts.
This is useful when serving multiple hosts from the same machine
with a different configuration for each.  For more information,
see the Virtual Host Documentation.
    

    top
    

    

    Proxy
    


    The <Proxy>
and <ProxyMatch>
containers apply enclosed configuration directives only
to sites accessed through mod_proxy's proxy server
that match the specified URL. For example, the following configuration
will allow only a subset of clients to access the
www.example.com website using the proxy server:
    


    <Proxy "http://www.example.com/*">
    Require host yournetwork.example.com
</Proxy>
    


    top
    

    

    What Directives are Allowed?
    


    To find out what directives are allowed in what types of
configuration sections, check the Context of the directive.
Everything that is allowed in
<Directory>
sections is also syntactically allowed in
<DirectoryMatch>,
<Files>,
<FilesMatch>,
<Location>,
<LocationMatch>,
<Proxy>,
and <ProxyMatch>
sections.  There are some exceptions, however:
    



    top
    

    

    How the sections are merged
    


    The configuration sections are applied in a very particular order.
Since this can have important effects on how configuration directives
are interpreted, it is important to understand how this works.
    

    
    The order of merging is:
    

    
      
      
    1.  <Directory> (except regular expressions)
      and .htaccess done simultaneously (with
      .htaccess, if allowed, overriding
      <Directory>)
      2. 

      
    2. <DirectoryMatch>
      (and <Directory "~">)
      3. 

      
    3. <Files> and <FilesMatch> done
      simultaneously
      4. 

      
    4. <Location>
      and <LocationMatch> done simultaneously
      5. 

      
    5. <If>
      
      6. 

    
    

    
    Some important remarks:
    
    
      
        
    • Apart from <Directory>, within each group the sections are
        processed in the order they appear in the configuration files.
        For example, a request for /foo/bar will match
        <Location "/foo/bar"> and 
        <Location "/foo"> (group 4 in this case):
        both sections will be evaluated
        but in the order they appear in the configuration files.
      • 
        
    • <Directory>
        (group 1 above) is processed in the order shortest directory
        component to longest. For example,
        <Directory "/var/web/dir"> will be processed before
        <Directory "/var/web/dir/subdir">.
      • 
        
    • If multiple <Directory> sections apply
        to the same directory they are processed in the configuration file
        order.
      • 
        
    • Configurations included via the Include directive will be treated as if
        they were inside the including file at the location of the
        Include directive.
      • 
        
    • Sections inside <VirtualHost> sections
        are applied after the corresponding sections outside
        the virtual host definition. This allows virtual hosts to
        override the main server configuration.
      • 
        
    • When the request is served by mod_proxy, the
        <Proxy>
        container takes the place of the <Directory> container in the processing
        order.
      • 
    
    

    
    Technical Note
    
      There is actually a
      <Location>/<LocationMatch>
      sequence performed just before the name translation phase
      (where Aliases and DocumentRoots
      are used to map URLs to filenames). The results of this
      sequence are completely thrown away after the translation has
      completed.
    
    


    Relationship between modules and configuration sections
    
    
    One question that often arises after reading how configuration sections are
    merged is related to how and when directives of specific modules like mod_rewrite
    are processed. The answer is not trivial and needs a bit of background. 
    Each httpd module manages its own configuration, and each of its directives in httpd.conf specify one piece 
    of configuration in a particular context. httpd does not execute a command as it is read.
    
    
    At runtime, the core of httpd iterates over the defined configuration sections in the order
    described above to determine which ones apply to the current request. When the first section matches, 
    it is considered the current configuration for this request. If a subsequent section matches too, 
    then each module with a directive in either of the sections is given a chance to merge its configuration between the two sections. The result is a third configuration, and the process goes on until all the configuration sections
    are evaluated.
    
    
    After the above step, the "real" processing of the HTTP request begins: each module has a chance to run 
    and perform whatever tasks they like. They can retrieve their own final merged configuration from the core
    of the httpd to determine how they should act.
    
    
    An example can help to visualize the whole process. The following configuration uses the 
        Header directive of mod_headers to set
        a specific HTTP header. What value will httpd set in the CustomHeaderName header for a request to
        /example/index.html ?
    
    
    
    <Directory "/">
    Header set CustomHeaderName one
    <FilesMatch ".*">
        Header set CustomHeaderName three
    </FilesMatch>
</Directory>

<Directory "/example">
    Header set CustomHeaderName two
</Directory>
    
    
    
      
        
    • Directory "/" matches and an initial configuration to set the CustomHeaderName header with the value one is created.
      • 
        
    • Directory "/example" matches, and since mod_headers specifies in its code to override in case of a merge, a new configuration is created to set the CustomHeaderName header with the value two.
      • 
        
    • FilesMatch ".*" matches and another merge opportunity arises, causing the CustomHeaderName header to be set with the value three.
      • 
        
    • Eventually during the next steps of the HTTP request processing mod_headers will be called and it will receive the configuration to set the CustomHeaderName header with the value three. mod_headers normally uses this configuration to perform its job, namely setting the foo header. This does not mean that a module can't perform a more complex action like discarding directives because not needed or deprecated, etc..
      • 
    
    

    
    This is true for .htaccess too since they have the same priority as Directory in the merge order. The important concept to understand is that configuration sections like  Directory and FilesMatch are not comparable to module specific directives like Header or RewriteRule because they operate on different levels.
    
    



    Some useful examples
    


    Below is an artificial example to show the order of
merging. Assuming they all apply to the request, the directives in
this example will be applied in the order A > B > C > D >
E.
    


    <Location "/">
    E
</Location>

<Files "f.html">
    D
</Files>

<VirtualHost *>
    <Directory "/a/b">
        B
    </Directory>
</VirtualHost>

<DirectoryMatch "^.*b$">
    C
</DirectoryMatch>

<Directory "/a/b">
    A
</Directory>
    




    For a more concrete example, consider the following.  Regardless of
any access restrictions placed in <Directory> sections, the <Location> section will be
evaluated last and will allow unrestricted access to the server.  In
other words, order of merging is important, so be careful!
    


    <Location "/">
    Require all granted
</Location>

# Whoops!  This <Directory> section will have no effect
<Directory "/">
    <RequireAll>
        Require all granted
        Require not host badguy.example.com
    </RequireAll>
</Directory>

    Apache のハンドラの使用に関して記述しています。

    ハンドラとは
    
    
    
    関連モジュール関連ディレクティブ
    


    
    「ハンドラ」とは、ファイルが呼ばれたときに実行される動作の
    Apache における内部表現です。
    通常、ファイルはファイルタイプ(訳注: MIME-type)に基づいた暗黙のハンドラがあります。
    普通はすべてのファイルは単にサーバに扱われますが、
    ファイルタイプの中には別に「ハンドル」(訳注: 扱う)
    されるものもあります。
    

    
    ファイルの拡張子や置いている場所に基づいてファイルタイプと関係なく、
    ハンドラを明示的に設定することもできます。
    これはより優雅な解決法という点と、ファイルにタイプとハンドラの両方を関連付けることができるという点で優れています。
    (複数の拡張子のあるファイルも参照してください)。
    

    
    ハンドラはサーバに組み込んだり、モジュールとして含めたり、
    Action
    ディレクティブとして追加したりすることができます。
    以下は標準配布に組み込まれているハンドラです。
    
    

    
      
      
    • default-handler:default_handelr()
      を使ってファイルを送ります。
      静的なコンテンツを扱うときにデフォルトで使用されるハンドラです。
      (core)
      • 

      
    • send-as-is:
      HTTP ヘッダのあるファイルをそのまま送ります。
      (mod_asis)
      • 

      
    • cgi-script: ファイルを CGI
      スクリプトとして扱います。
      (mod_cgi)
      • 

      
    • imap-file:
      イメージマップのルールファイルとして解析します。
      (mod_imagemap)
      • 

      
    • server-info: サーバの設定情報を取得します。
      (mod_info)
      • 

      
    • server-status: サーバの状態報告を取得します。
      (mod_status)
      • 

      
    • type-map:
      コンテントネゴシエーションのためのタイプマップとして解析します。
      (mod_negotiation)
      • 
    
    
  
    top
    

    

    例
    
    

    
    CGI スクリプトを用いて静的なコンテンツを変更する
    
      

      
    以下のディレクティブによって、拡張子が html
      であるファイルは footer.pl
      CGI スクリプトを起動するようになります。
    

      
    Action add-footer /cgi-bin/footer.pl
AddHandler add-footer .html
    


      
    CGI スクリプトは希望の修正や追加を行なって、元々要求された文書
      (環境変数 PATH_TRANSLATED
      で指されています) を送る責任があります。
      
    

    
    
    HTTP ヘッダのあるファイル
    
      

      
    以下のディレクティブは send-as-is
      ハンドラを使用するように指示します。このハンドラは自分自身の HTTP
      ヘッダを持っているファイルに使用されます。ここでは、拡張子に関わらず、
      /web/htdocs/asis ディレクトリにある全てのファイルは
      send-as-is ハンドラによって扱われます。
    

      
    <Directory /web/htdocs/asis>
    SetHandler send-as-is
</Directory>
    


    
  
    top
    

    

    プログラマ向けのメモ
    
    

    
    ハンドラの機能を実装するために、利用すると便利かもしれないものが
    Apache API
    に追加されました。詳しく言うと、request_rec
    構造体に新しいレコードが追加されたということです。
    

    
    char *handler
    


    
    もしモジュールがハンドラに関わりたい場合、
    やらなければならないことは、リクエストが invoke_handler
    ステージに達する以前に r->handler
    を設定することだけです。ハンドラはコンテントタイプの代わりに
    ハンドラ名を使うようになっていること以外は、以前と同じように実装されています。
    必ず要求されているわけではありませんが、メディアタイプ
    の名前空間を侵さないように、ハンドラの名前にはスラッシュを含まない、
    ダッシュ(訳注: "-")で分離された名前を付ける習慣になっています。

    Konfiguration der vom Apache HTTP Server verwendeten Adressen und
    Ports.
    
  
    


    top
    

    

    Überblick
    
    

    
    Referenzierte ModuleReferenzierte Direktiven
    

    
    Beim Start bindet sich der httpd an bestimmte Adressen und Ports
    der lokalen Maschine und wartet auf eingehende Anfragen.
    Standardmäßig lauscht er an allen Adressen des Systems.
    Es kann jeodch notwendig sein, ihm mit zuteilen, nur an bestimmten
    Ports zu lauschen oder nur an ausgewählten Adressen, bzw. einer
    Kombination aus beidem. Dies wird oft mit der Funktionalität virtueller Hosts kombiniert, die bestimmt, wie
    der httpd auf verschiedene IP-Adressen, Hostnamen und
    Ports reagiert.
    

    
    Die Direktive Listen
    weist den Server an, eingehende Anfragen nur an bestimmten Port(s)
    oder Adress/Port-Kombinationen zu akzeptieren. Wenn bei der
    Listen-Direktive nur eine
    Portnummer angegeben wird, dann lauscht der Server auf allen
    Netzwerkinterfaces an dem angegebenen Port. Ist auch eine IP-Adresse
    angegeben, dann lauscht der Server an der angegebenen Schnittstelle
    auf dem angegebenen Port.  Es können mehrere Listen-Anweisungen verwendet werden,
    um eine Reihe von Adressen und Ports anzugeben, an denen gelauscht
    werden soll. Der Server wird dann auf Anfragen an jeder der
    abgehörten Adressen und Ports antworten.
    

    
    Um beispielsweise den Server zu veranlassen, auf allen
    Netzwerkinterfaces sowohl an Port 80, als auch an Port 8000
    Verbindungen zu akzeptieren, geben Sie an:
    

    
    Listen 80
Listen 8000
    

    

    
    Um den Server Verbindungen an Port 80 auf einem Netzwerkinterface
    akzeptieren zu lassen und an Port 8080 auf einem anderen Interface, geben
    Sie an:
    
      
    
    Listen 192.0.2.1:80
Listen 192.0.2.5:8000
    

    

    
    IPv6-Adressen müssen wie im folgenden Beispiel in eckigen
      Klammern angegeben werden:
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    

    

    
    Sich überlappende Listen-Direktiven generieren einen
    fatalen Fehler, der verhindert, dass der Server hochfährt.
    

    
    
      (48)Address already in use: make_sock: could not bind to address [::]:80
    
    

    
    Diese
    Diskussion im Wiki gibt weitere Tipps zur Fehlerbehebung.
    
    
    
  
    top
    

    

    Betrachtung von IPv6-Besonderheiten
    
    

    
    Eine wachsende Anzahl von Plattformen implementiert IPv6. Die
    APR unterstützt IPv6 auf den meisten
    dieser Plattformen und ermöglicht dem httpd, IPv6-Sockets zu
    verwenden und über IPv6 gesendete Anfragen zu behandeln.
    

    
    Für httpd-Administratoren kommt erschwerend die Frage hinzu,
    ob IPv6-Sockets sowohl IPv4- als auch IPv6-Verbindungen handhaben
    können. Zum Betrieb von IPv4-Verbindungen an IPv6-Sockets
    werden auf IPv6 abgebildete IPv4-Adressen (Anm.d.Ü.: so genannete
    IPv4-gemappte IPv6-Adressen) verwendet, welche
    standardmäßig auf den meisten Plattformen erlaubt sind.
    Unter FreeBSD, NetBSD und OpenBSD jedoch sind sie
    standardmäßig deaktiviert, um den Systemgrundsätzen
    dieser Plattformen zu entsprechen. Auf Systemen, wo dies
    standardmäßig dekativiert ist, kann dieses Verhalten mit
    einem speziellen configure-Parameter für den
    httpd geändert werden.
    

    
    Auf der anderen Seite ist die Verwendung von gemappten Adressen
    bei einigen Plattformen wie Linux und True64 der
    einzige Weg, sowohl IPv4 wie auch IPv6 zu
    verwenden. Wenn Sie möchten, dass der httpd IPv4-
    und IPv6-Verbindungen mit einem Minimum an Sockets behandelt, was
    die Verwendung von IPv4-gemappten IPv6-Adressen erfordert, dann
    müssen Sie die configure-Option
    --enable-v4-mapped angeben.
    

    
    --enable-v4-mapped ist die Voreinstellung auf allen
    Plattformen außer FreeBSD, NetBSD und OpenBSD, so dass Ihr
    httpd wahrscheinlich so übersetzt wurde.
    

    
    Geben Sie wie in dem folgenden Beispiel bei allen Listen-Anweisungen eine IPv4-Adresse
    an, wenn Sie möchten, dass Ihr httpd lediglich IPv4-Adressen
    behandelt, unabhängig davon, was Ihre Plattform und die APR
    unterstützen:
    

    
    Listen 0.0.0.0:80
Listen 192.0.2.1:80
    

    

    
    Wenn Sie möchten, dass der httpd IPv4- und IPv6-Verbindungen
    an separaten Sockets behandelt (d.h. IPv4-gemappte Adressen
    deaktiviert werden sollen) und Ihre Plattform es unterstützt,
    dann müssen Sie die configure-Option
    --disable-v4-mapped angeben.  Unter FreeBSD, NetBSD und
    OpenBSD ist --disable-v4-mapped voreingestellt.
    
  
    top
    

    

    Angabe des Protokolls bei Listen
    
    
    
    Das optionale zweite Protokoll-Argument von Listen ist für die meisten
    Konfigurationen gar nicht erforderlich. Wenn nicht angegeben, sind
    https für Port 443 und http für
    alle anderen Ports die Voreinstellungen. Die Protokollangabe wird
    sowohl dazu verwendet, herauszufinden, welches Modul Anfragen
    verarbeiten soll, als auch, um protokollspezifische Optimierungen
    bei der AcceptFilter-Direktive
    zu aktivieren.
    

    
    Sie müssen das Protokoll nur angeben, wenn Sie
    ungewöhnliche Ports benutzen, beispielsweise https
    auf Port 8443:
    

    
    Listen 192.170.2.1:8443 https
    

    
  
    top
    

    

    Das Zusammenspiel mit virtuellen Hosts
    
    

    
    Die Direktive Listen
    implementiert keine virtuellen Hosts - sie teilt dem Hauptserver
    lediglich mit, an welchen Adressen und Ports er zu lauschen hat.
    Werden keine <VirtualHost>-Container verwendet, dann
    verhält sich der Server bei allen angenommenen Anfragen gleich.
    <VirtualHost>-Abschnitte können jedoch
    dazu verwendet werden, ein unterschiedliches Verhalten für eine
    oder mehrere Adressen und Ports festzulegen. Um einen virtuellen
    Host einzurichten, muss dem Server zunächst mitgeteilt werden,
    an den betreffenden Adressen oder Ports zu lauschen. Dann sollte ein
    <VirtualHost>-Abschnitt für die
    angebene Adresse und den angegebenen Port erstellt werden, um das
    Verhalten dieses virtuellen Hosts festzulegen. Beachten Sie bitte,
    dass auf einen <VirtualHost> nicht zugegriffen werden
    kann, wenn er für eine Adresse und einen Port eingerichtet
    wurde, an dem der Server nicht lauscht.

    Apache HTTP Sunucusunu etkileyen ortam değişkenleri iki çeşittir.
    

    
    İlki, işletim sisteminin denetimindeki ortam değişkenleridir. Bu
      değişkenlere değer atama işlemi sunucu başlatılmadan önce yapılır.
      Bunlar yapılandırma dosyalarının içinde kullanılabilir. Ayrıca,
      istenirse PassEnv yönergesi kullanılarak bunlar CGI betiklerine ve
      SSI sayfalarına da aktarılabilir.
    

    
    İkincisi ise, Apache HTTP Sunucusunun kendi ortam değişkenleridir.
      Bu değişkenlerde saklanan bilgi erişim denetimi, günlük kaydı gibi
      çeşitli işlemleri denetlemekte kullanılabilir. Değişkenler ayrıca, CGI
      betikleri gibi harici uygulamalarla iletişim mekanizması olarak da
      kullanılabilir. Bu belgede bu değişkenler üzerindeki işlemlere ve
      kullanım şekillerine değinilmiştir.
    

    
    Bu değişkenlere ortam değişkenleri dense de işletim sisteminin
      ortam değişkenleri gibi değillerdir. Bunlar sadece Apache ortamında
      geçerli değişkenler olup işletim sisteminin bu değişkenlerden haberi
      olmaz. Sadece CGI betikleri ve SSI sayfaları gibi harici uygulamalar
      tarafından üretilen ortam değişkenleri sistem ortamının değişkenleri
      haline gelirler. İşletim sistemi ortamına çalışmakta olan sunucudan
      müdahale etmek isterseniz işletim sisteminizin kabuğu tarafından sağlanan
      standart ortam müdahale mekanizmalarını kullanmalısınız.

    Ortam Değişkenlerinin Atanması
    
    
    
    İlgili Modüllerİlgili Yönergeler
    

    
    Temel Ortamda Değişiklik
    
        

        
    Apache ortamında bir ortam değişkenine müdahale etmenin en temel
          yolu hiçbir koşula tabi olmayan SetEnv yönergesini kullanmaktır. Bu değişkenleri Apache
          başlatılırken sistem ortam değişkenleri haline getirmek için
          PassEnv yönergesi
          kullanılabilir.
    

    
    
    İsteğe Bağlı Şartlı Atamalar
    
        

        
    Esnekliği arttırmak için, mod_setenvif modülü ile
          isteğin özelliklerine uygun olarak her isteğe özel değişkenler
          atayabilmek mümkün kılınmıştır. Örneğin, bir değişken sadece isteği
          yapan tarayıcıya özgü bir değerle veya sadece belli bir başlık
          alanınına bağlı olarak atanabilir. Daha da esnek bir mekanizma,
          ortam değişkeni atamak için [E=...] seçeneğinin
          kullanıldığı mod_rewrite modülünün RewriteRule yönergesi ile
          sağlanmıştır.
    

    
    
    Eşsiz Betimleyiciler
    
        

        
    Son olarak, mod_unique_id UNIQUE_ID
          ortam değişkenine her istek için o isteğin çok özel koşullar altında
          tüm diğer istekler arasında eşsizliğini garanti edecek bir değer
          atar.
    

    
    
    Standart CGI Değişkenleri
    
        

        
    Apache yapılandırmasıyla atanan ve kabuğa aktarılan ortam
          değişkenlerinden başka CGI
          Belirtiminin gerektirdiği istekler hakkında temel bilgileri
          içeren ortam değişkenlerinin CGI betikleri ve SSI sayfalarınca
          atanabilmesi sağlanmıştır.
    

    
    
    Bazı Yetersizlikler
    
        

        
      
          
    • Standart CGI değişkenlerini ortam değişkenlerine müdahale
            yönergelerini kullanarak değiştirmek veya geçersiz kılmak mümkün
            değildir.
      • 

          
    • CGI betiklerini çalıştırmak için suexec
            kullanıldığında ortam, CGI betikleri çalıştırılmadan önce
            güvenilir değişkenler kalacak şekilde temizlenir.
            Güvenilir değişken listesi suexec.c içinde
            derleme sırasında tanımlanır.
      • 

          
    • Taşınabilirlik adına, ortam değişkenlerinin isimleri sadece
            harfler, rakamlar ve alt çizgi imlerini içerebilir. Bunlara ek
            olarak ismin ilk karakteri bir rakam olmamalıdır. Değişkenler CGI
            betiklerine ve SSI sayfalarına aktarılırken bu sınırlamalara uygun
            olmayan karakterlerin yerlerine alt çizgi imleri konur.
      • 

          
    • Bir özel durum, CGI betiklerine ve benzerlerine ortam
            değişkenleri üzerinden aktarılan HTTP başlıklarıdır (aşağıya
            bakın). Bunlar büyük harfe dönüştürülür ve sadece tireler
            altçizgilere dönüştürülür. Eğer HTTP başlığı geçersiz karakter
            içeriyorsa başlığın tamamı yoksayılır. Böyle bir durumda ne
            yapılacağı öğrenmek için aşağıya
            bakın.
      • 

          
    • İsteklerin işleme konması sırasında SetEnv yönergesi geç çalıştırılır,
            yani SetEnvIf ve
            RewriteCond gibi
            yönergeler SetEnv ile
            atanan değişken değerlerini görmezler.
      • 

          
    • mod_autoindex ile dizin listesi oluşturulması
            veya bir DirectoryIndex
            için yol aranması gibi bir dahili alt
            istek için sunucu yol araması yaparken isteklere özgü
            ortam değişkenleri alt istekler tarafından miras alınMAZ. Buna ek
            olarak, mod_setenvif modülünün devreye girdiği API

    Ortam Değişkenlerinin Kullanımı
    
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    CGI Betikleri
    
        

        
    Ortam değişkenlerinin başlıca amaçlarından biri CGI betikleriyle
          iletişim kurmaktır. Yukarıda bahsedildiği gibi CGI betiklerine
          aktarılan ortam Apache yapılandırmasında atanan değişkenlere ek
          olarak istek hakkında standart temel bilgileri de içerir. Bu konuda
          ayrıntılı bilgi edinmek için CGI
          Öğreticisine bakabilirsiniz.
    

    
    
    SSI Sayfaları
    
        

        
    Sunucu tarafında mod_include modülünün
          INCLUDES süzgeci ile yorumlanan SSI sayfalarında ortam
          değişkenleri echo elemanı ile basılabilir ve sayfayı
          isteğin özelliklerine uygun olarak oluşturmak için ortam
          değişkenleri akış denetim elemanları içinde kullanılabilir. Apache
          ayrıca, yukarıda bahsedildiği gibi standart CGI ortam değişkenli SSI
          sayfalarını da sağlayabilmektedir. Daha ayrıntılı bilgi edinmek için
          SSI Öğreticisine bakabilirsiniz.
    

    
    
    Erişim Denetimi
    
        

        
    Require env ve Require not env
          yönergeleri sayesinde ortam değişkenlerine dayalı olarak sunucuya
          erişim denetim altında tutulabilir. Bunlar SetEnvIf yönergesi ile birlikte
          kullanılmak suretiyle sunucuya erişim isteğin özelliklerine bağlı
          olarak daha esnek bir tarzda denetlenebilir. Örneğin, belli bir
          tarayıcının sunucuya erişimi bu yönergelerle engellenebilir.
    

    
    
    Şartlı Günlük Kaydı
    
        

        
    Ortam değişkenleri LogFormat yönergesinin %e seçeneği
          kullanılarak erişim günlüğüne kaydedilebilir. Bundan başka,
          CustomLog yönergesi
          sayesinde isteklerin günlüğe kaydedilip kaydedilmeyeceğine ortam
          değişkenlerine dayalı olarak karar verilmesi sağlanabilir. Bunlar
          SetEnvIf yönergesi ile
          birlikte kullanılmak suretiyle günlük kayıtları isteğin
          özelliklerine bağlı olarak daha esnek bir tarzda denetlenebilir.
          Örneğin, gif uzantılı dosyalar için yapılan isteklerin
          günlüğe kaydedilmemesi veya sadece alt ağınızın dışından gelen
          isteklerin günlüğe kaydedilmesini isteyebilirsiniz.
    

    
    
    Şartlı Yanıt Başlıkları
    
        

        
    Header yönergesi belli
          bir yanıt başlığının istemciye gönderilip gönderilmeyeceğine belli
          bir ortam değişkeninin varlığına bakarak karar vermek için
          kullanılabilir. Böylece örneğin, belli bir başlığın istemciye
          gönderilmesine istemciden belli bir başlığın alınıp alınmadığına
          bağlı olarak karar verilebilir.
    

    

    
    Harici Süzgeçlerin Etkinleştirilmesi
    
        

        
    mod_ext_filter tarafından yapılandırılan harici
          süzgeçler ExtFilterDefine yönergesinin disableenv= ve
          enableenv= seçenekleri kullanılarak bir ortam
          değişkenine bağlı olarak etkinleştirilebilir.
    
    

    
    URL Kurgulaması
    
        

        
    RewriteCond
          yönergesinin SınamaDizgesi olarak kullanılan
          %{ENV:değişken} biçemi
          mod_rewrite yeniden yazma motorunun ortam
          değişkenlerine bağlı kararlar almasını mümkün kılar. Yalnız şuna
          dikkat ediniz: mod_rewrite’ta ENV:
          öneki kullanılmadan belirtilen değişkenler ortam değişkenleri
          değillerdir. Onlar mod_rewrite’a özgü diğer
          modüllerden erişilemeyen özel değişkenlerdir.

    Özel Amaçlı Ortam Değişkenleri
    
    

        
    Birlikte çalışabilirlik sorunları Apache’nin belli istemcilerle
          veri alışverişi sırasında davranışını değiştirmesini gerektirebilir.
          Genellikle SetEnv ve
          PassEnv yönergelerinden
          başka BrowserMatch
          gibi yönergelerle ortam değişkenleri atanarak bunu sağlayan
          mekanizmaların olabildiğince esnek davranabilmesi sağlanabilir.
    

    
    downgrade-1.0
    
        

        
    İstek, daha yüksek bir HTTP protokolüyle yapılmış olsa bile
          HTTP/1.0 isteği olarak ele alınır.
    

    
    
    force-gzip
    
        
          
    DEFLATE süzgeci etkinse tarayıcının tercih ettiği
            kodlama koşulsuz olarak yoksayılarak sıkıştırılmış çıktı
            gönderilir.
    
    
    
    force-no-vary
    
        

        
    İstemciye gönderilmeden önce yanıttan Vary alanının
          çıkarılmasına sebep olur. Bazı istemciler bu alanı gerektiği gibi
          yorumlayamazlar, bu değişken atanarak bu sorunla karşılaşılmamaya
          çalışılır. Bu değişkenin atanması ayrıca
          force-response-1.0 değişkeninin de atanmasına sebep
          olur.
    

    
    
    force-response-1.0
    
        

      
    HTTP/1.0 isteği yapan istemcilere HTTP/1.0 yanıtı verilmesini zorunlu
        kılar. AOL vekillerindeki bir sorun nedeniyle gerçeklenmiştir. Bazı
        HTTP/1.0 istemciler HTTP/1.1 yanıtlarında doğru davranmayabilirler; bu
        değişken atanarak bunların sorunları giderilebilir.
    

    

    
    gzip-only-text/html
    
        

        
    Bu değişkene "1" değeri atandığında text/html’den
          farklı içerik türleri için mod_deflate modülü
          tarafından sağlanan DEFLATE  çıktı süzgeci iptal
          edilir. Sıkıştırılmış olarak saklanan dosyalar kullanıyorsanız bu
          değişkeni mod_negotiation modülü de dikkate alır
          (kimliğine bakarak sadece gzip için değil, tüm kodlamalar için bunu
          yapar).
    
    

    
    no-gzip
    

        
    Bu değişken atandığında, mod_deflate modülünün
          DEFLATE süzgeci kapatılır ve
          mod_negotiation modülü kodlanmış kaynak teslimatını
          reddeder.
    

    

    
    no-cache
    
        
    2.2.12 sürümünden beri kullanılabilmektedir.
    

        
    Atandığı takdirde, mod_cache artık
        önbelleklenebilecek yanıtları kaydetmeyecektir. Bu ortam değişkeni bir
        yanıtın halihazırda mevcut bir isteğe sunulmak üzere önbellekte olup
        olmadığından etkilenmez.
    

    

    
    nokeepalive
    
        

        
    Bu değişken atandığında, KeepAlive yönergesi iptal edilir.
    

    

    
    prefer-language
    
        

        
    Değer olarak en, ja veya
          x-klingon gibi bir dil kısaltması verilerek atanmışsa
          mod_negotiation modülünün normal davranışını
          değiştirerek belirtilen dilde bir teslimat yapılmaya çalışılır.
          Böyle bir belge yoksa normal uzlaşım süreci uygulanır.
    

    

    
    redirect-carefully
    
        

        
    İstemciye bir yönlendirme gönderirken sunucuyu daha dikkatli olmaya
          zorlar. Bu genellikle istemcinin yönlendirmeler konusunda sorunlu
          olduğu bilindiği takdirde yararlı olur. Bu değişkenin gerçeklenme
          sebebi, dizin kaynaklarına yönlendirmeler için DAV yöntemlerini
          kullanan Microsoft'un WebFolders yazılımındaki bir sorundur.
    

    

   
    suppress-error-charset
    
       

    
    2.0.54 sürümünden beri mevcuttur.
    

    
    Apache bir isteğe bir yönlendirme ile yanıt verdiğinde istemci
      yönlendirmeyi kendiliğinden yapmaz veya yapamazsa kullanıcıya yanıtla
      birlikte gönderilen metin gösterilir. Apache normal olarak bu metni
      ISO-8859-1 ile kodlar.
    

    
    Ancak, yönlendirmenin yapıldığı sayfa farklı bir karakter kümesine
      sahipse bazı tarayıcı sürümleri asıl sayfanın karakter kodlaması yerine
      yönlendirmenin kodlamasını kullanmaya çalışırlar. Bu özellikle Yunanca
      gibi dillerde hedef sayfanın hatalı yorumlanmasına yol açar.
    

    
    Bu ortam değişkeninin atanması Apache’nin yönlendirme için karakter
      kümesi belirtmemesini sağlamak suretiyle hatalı tarayıcıların hedef
      sayfayı yanlış karakter kodlamasıyla yorumlamasını önler.
    

    
    
      
    Güvenlik Uyarısı
    

      
    Hata sayfalarının bir karakter kümesi belirtilmeksizin yollanması,
        HTTP/1.1 belirtimine uymayan ve karakter kümesini içeriğe bakarak
        tahmin etmeye çalışan tarayıcılarda (MSIE) karşı siteden betik
        saldırısı yorumuna sebep olabilir.  Girdi verisindeki UTF-7 içerik
        (istek betimleyici gibi) karşı siteden betik saldırılarını engellemek
        için tasarlanmış normal önceleme mekanizmalarıyla öncelenmeyeceği için
        böyle tarayıcılar UTF-7 karakter kodlaması kullanılarak kolayca
        aldatılabilir.
    
    
    

   

   
    force-proxy-request-1.0,
    proxy-nokeepalive, proxy-sendchunked ve
    proxy-sendcl, proxy-chain-auth,
    proxy-interim-response, proxy-initial-not-pooled
    
    

   
    Bu yönergeler mod_proxy modülünün normal protokol
    davranışını değiştirirler. Daha ayrıntılı bilgi için
    mod_proxy ve mod_proxy_http
    belgelerine bakınız.
    
   

  
    top
    

    

    Örnekler
    
    

    
    Bozuk başlıkların CGI betiklerine aktarılması
    
      

      
    2.4 sürümünden itibaren, mod_cgi modülü ve diğer
        modüllerde HTTP başlıklarının ortam değişkenlerine dönüştürülmesi
        bağlamında Apache daha seçici davranmaktadır. Önce HTTP başlığındaki
        geçersiz karakterlerin tamamı altçizgilere dönüştürülür. Bu, başlık
        zerki yoluyla yapılan karşı-site-betiklerini-çalıştırma saldırısını
        önlemeye yöneliktir. (Bakınız: Unusual Web Bugs, slide 19/20).
    

      
    Bozuk başlıklar gönderdiği halde bunlara dokunulmamasını gerektiren
        bir istemciniz varsa, mod_setenvif ve
        mod_headers modüllerinin sunduğu yapıyı örnekteki gibi
        kullanarak bu sorunun üstesinden gelebilirsiniz:
    

      
    #
# Aşağıdaki satırlarla bir istemcinin gönderdiği bozuk
# Accept_Encoding başlıklarının istenildiği gibi işlenmesi
# sağlanabilir.
#
SetEnvIfNoCase ^Accept.Encoding$ ^(.*)$ fix_accept_encoding=$1
RequestHeader set Accept-Encoding %{fix_accept_encoding}e env=fix_accept_encoding
    


    

    
    Protokolü yanlış yorumlayan tarayıcıların davranışlarının
        değiştirilmesi
    
        

        
    Önceki sürümlerde bilinen istemci davranışlarına karşı önlem olarak
          aşağıdaki satırların httpd.conf içinde bulunması
          önerilirdi. Fakat, böyle tarayıcılar artık ortalıkta görünmediğinden
          bu yapılandırmaya da artık gerek kalmamıştır.
    

        
    #
# Aşağıdaki yönergeler normal HTTP yanıt davranışını değiştirirler.
# İlk yönerge Netscape 2.x ve kendini öyle gösteren tarayıcılar için
# kalıcı bağlantıyı (keepalive) iptal eder. İkinci yönerge ise HTTP/1.1
# protokolü bozuk olan ve 301/302 durum kodlu yönlendirme yanıtları
# kullanıldığında kalıcı bağlantıları gerektiği gibi desteklemeyen
# Microsoft Internet Explorer 4.0b2 içindir.
#
BrowserMatch "Mozilla/2" nokeepalive
BrowserMatch "MSIE 4\.0b2;" nokeepalive downgrade-1.0 force-response-1.0

#
# Aşağıdaki yönergeler HTTP/1.0 yanıtlarından başkasına yabancı olan
# tarayıcılara HTTP/1.1 yanıtlarının gönderilmesini iptal eder.
#
BrowserMatch "RealPlayer 4\.0" force-response-1.0
BrowserMatch "Java/1\.0" force-response-1.0
BrowserMatch "JDK/1\.0" force-response-1.0
    


    
    
    Resim isteklerinin erişim günlüğüne kaydedilmemesi
    
        

        
    Bu örnek resim isteklerinin erişim günlüğüne yazılmasını engeller.
          Bu örnek değiştirilerek belli dizinlerin veya belli konaklardan
          gelen isteklerin günlüğe kaydedilmesini engellemek amacıyla da
          kullanılabilir.
    

        
    SetEnvIf Request_URI \.gif image-request
SetEnvIf Request_URI \.jpg image-request
SetEnvIf Request_URI \.png image-request
CustomLog "logs/access_log" common env=!image-request
    



    
    
    “Resim Hırsızlığı” için önlem alınması
    
        

        
    Bu örnekte sunucunuzda bulunmayan sayfalarda sunucunuzdaki
          resimlerin kullanılmasının nasıl önleneceği gösterilmiştir. Bu
          yapılandırma önerilmemekle birlikte nadir durumlarda işe yarar. Tüm
          resimlerin /siteler/resimler dizini altında tutulduğu
          varsayılmıştır.
    

        
    SetEnvIf Referer "^http://www\.example\.com/" local_referal
# Referrer bilgisi göndermeyen tarayıcılara izin verelim
SetEnvIf Referer "^$" local_referal
<Directory "/siteler/resimler">
  Require env local_referal
</Directory>
    


        
    Bu teknik hakkında daha ayrıntılı bilgi edinmek için ServerWatch
          üzerindeki  "Diğer sitelerin sizin resimlerinizle donatılmasını engellemek"
          belgesine bakınız.

    Esse documento descreve algumas das principais mudanças
     entre as versões 2.0 e 2.2 do Servidor HTTP Apache.
     Para a lista de mudanças desde a versão 1.3, veja a página
     de documentação novas funcionalidades
     do Apache 2.0.
    

    


    top
    

    

    Principais Melhorias
    
    
    
    

      
    Authn/Authz
    
      
    ...
    

      
    Caching
    
      
    ...
    

      
    Proxying
    
      
    O novo módulo mod_proxy_balancer fornece
          serviços de carregamento de balenceamento para mod_proxy. O novo módulo mod_proxy_ajp oferece suporte para o Protocolo Apache JServ
          versão 1.3, usado pelo Apache Tomcat.
    

      
    Filtragem Inteligente (Smart Filtering)
    
      
    O mod_filter introduz configuração dinâmica para
          o filtro de saída de dados. Permitindo que os filtros sejam
	  condicionalmente inseridos, baseando-se nos cabeçalhos Request ou Response ou em variáveis do
	  ambiente, ele acaba com os problemas de dependências e pedidos
          da arquitetura 2.0.

    Melhorias nos Módulos
    
    
    
    
      
    mod_authnz_ldap
    
      
    Este módulo é uma migração do mod_auth_ldap,
          da versão 2.0 para a estrutura 2.2 de Authn/Authz.
	  As novas funcionalidades incluem o uso de atributos LDAP e
	  filtros de procura complexos na diretriz Require.
    

      
    mod_info
    
      
    Adicionado um novo argumento ?config que
          mostra a configuração das diretrizes analisadas pelo
	  Apache, incluindo o nome do arquivo e o número da linha.
	  Esse módulo também mostra a ordem de todos os ganchos de
          pedidos (request hooks) e informações adicionais sobre
          a compilação, similar ao comando httpd -V.
    
    
    
  
    top
    

    

    Mudanças ao Desenvolvedor de Módulos
    
    
    
    
      
    API do APR 1.0
    

      
    O Apache 2.2 utiliza a API do APR 1.0. Todas as funções e
          símbolos antigos foram removidos do APR e
	  APR-Util. Para mais detalhes, visite o
          Website do APR.
    

      
    Registros de Erros de Conexão (logs)
    

      
    Uma nova função ap_log_cerror, foi adicionada
          para registrar erros que ocorrem na conexão do cliente.
	  Quando documentado no diário de log, a mensagem inclui o
	  endereço IP do cliente.
    

      
    Adicionado Gancho de Teste de Configuração
    

      
    Um novo gancho (hook), test_config foi
          adicionado para auxiliar módulos que querem executar
	  códigos especiais apenas quando o usuário passa o
	  parâmetro -t para o httpd.
    

      
    Ajustar o Stacksize dos "Threaded MPM's"
    

      
    Uma nova diretriz chamada ThreadStackSize,
          foi adicionada para ajustar o tamanho das stacks em todos
          os threadeds MPMs. Essa é uma prática necessário para alguns
	  módulos de terceiros em plataformas com tamanhos de stacks
	  pequenos por padrão.
    

      
    Negociação de Protocolo para filtros de saída
    

      
    No passado, todo filtro era responsável por garantir
          a geração de cabeçalhos de resposta correto que os afetava.
	  Os filtros agora podem delegar o gerenciamento de protocolos
	  comuns para mod_filter, usando chamadas
	  de ap_register_output_filter_protocol ou
          ap_filter_protocol.

    Configuration du serveur HTTP Apache pour l'écoute

    Vue d'ensemble
    
    

    
    Modules ApparentésDirectives Apparentées
    


    
    Au démarrage de httpd, un port et une adresse lui sont associés sur
    l'hôte local et le serveur se met en attente de l'arrivée d'une requête.
    Par défaut, le serveur écoute toutes les adresses de l'hôte local.
    Cependant, on peut lui préciser des ports et des adresses spécifiques à
    écouter, ou une combinaison des deux.  Tout ceci est souvent associé avec la
    fonctionnalité des serveurs virtuels qui détermine la
    manière dont httpd répond aux différents ports, noms d'hôtes et
    adresses IP.
    

    
    La directive Listen permet
    d'indiquer au serveur qu'il ne doit accepter des requêtes que sur le(s)
    port(s) spécifiés ou une combinaison adresse/port. Si seul un numéro de port
    est spécifié dans la directive Listen, le serveur se met à l'écoute sur ce
    port et sur toutes les interfaces réseau.  Si une adresse IP est spécifiée
    en plus du port, le serveur va écouter sur ce port et uniquement sur
    l'interface réseau correspondante. On peut utiliser plusieurs directives
    Listen pour spécifier plusieurs
    adresses et ports à écouter. Le serveur répondra alors aux requêtes sur tous
    les ports et adresses spécifiés.
    

    
    Par exemple, pour faire en sorte que le serveur accepte des connexions
    sur les ports 80 et 8000 et sur toutes les interfaces, utilisez :
    

    
    Listen 80
Listen 8000
    

    

    
    Pour faire en sorte que le serveur accepte des connexions sur le port 80
    pour une interface, et sur le port 8000 pour une
    autre interface, utilisez :
    

    
    Listen 192.0.2.1:80
Listen 192.0.2.5:8000
    

    

    
    Les adresses IPv6 doivent être mises entre crochets, comme dans
    l'exemple suivant :
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    

    

    
    Des directives Listen
    imbriquées provoqueront une erreur fatale qui
    empêchera le serveur de démarrer.
    

    
    
      (48)Address already in use: make_sock: could not bind to address [::]:80
    
    

    
    Voir cette
    discussion dans le wiki pour plus de détails à propos de la résolution
    de ce problème.
    

    
    

  
    top
    

    

    Changer la configuration de l'écoute au redémarrage
    
    

    
    Lorsque httpd est redémarré, certaines remarques sont à prendre en compte
    quant aux modifications apportées aux directives Listen. Au cours du redémarrage, httpd
    conserve la liaison avec les ports de la configuration précédente afin
    d'éviter l'obtention d'un message d'erreur "Connection refused" lors d'une
    tentative ultérieure de connexion au serveur. Si les modifications apportées au jeu de
    directives Listen utilisé entrent
    en conflit avec ce dernier, le serveur refusera de redémarrer.
    

    
    Par exemple, modifier la configuration suivante :
    
    
    
    Listen 127.0.0.1:80
    

    

    
    pour utiliser la suivante pourra échouer car écouter le port 80 sur
    toutes les adresses IP entre en conflit avec une écoute sélective du port 80
    sur la seule adresse IP 127.0.0.1.
    
    
    
    Listen 80
    

    

    
    Pour qu'une telle modification de configuration soit prise en compte avec
    succès, il est nécessaire d'arrêter, puis de démarrer le serveur.
    
    
  
    top
    

    

    Remarques spécifiques à IPv6
    
    

    
    Un nombre croissant de plateformes implémentent IPv6, et
    APR supporte IPv6 sur la plupart d'entre elles,
    ce qui permet à httpd d'allouer des points de connexion (sockets) IPv6
    et de traiter des requêtes envoyées sur IPv6.
    

    
    Les administrateurs de httpd doivent se préoccuper de la possibilité
    pour un point de connexion IPv6 de traiter à la fois des connexions IPv4
    et des connexions IPv6.
    Le traitement de connexions IPv4 avec un point de connexion IPv6 utilise
    des adresses IPv6 traduites en IPv4 qui sont autorisées par défaut sur la
    plupart des plateformes, mais sont interdites par défaut sous FreeBSD, NetBSD,
    et OpenBSD, afin de respecter la politique de sécurité du système sur ces plateformes.
    Sur les systèmes où ces adresses sont interdites par défaut, un
    paramètre spécial du script configure permet de modifier
    ce comportement pour httpd.
    

    
    En revanche, sur certaines plateformes comme Linux et Tru64, la
    seule manière de gérer à la fois IPv6 et IPv4 passe
    par l'utilisation d'adresses traduites. Si vous voulez que httpd gère
    des connexions IPv4 et IPv6 avec un minimum de points de connexion,
    ce qui nécessite l'utilisation d'adresses IPv6 traduites en IPv4,
    utilisez l'option --enable-v4-mapped du script configure.
    

    
    L'option --enable-v4-mapped est utilisée par défaut sur
    toutes les plateformes sauf FreeBSD, NetBSD, et OpenBSD;
    votre httpd a donc probablement été construit avec cette option.
    

    
    Si vous souhaitez que httpd ne gère que des connexions IPv4, sans se
    soucier de ce que votre plateforme et APR supportent, spécifiez une adresse
    IPv4 dans toutes les directives
    Listen, comme dans l'exemple
    suivant :
    

    
    Listen 0.0.0.0:80
Listen 192.0.2.1:80
    

    

    
    Si votre plateforme le supporte et si vous souhaitez que httpd gère
    des connexions IPv4 et IPv6 sur des points de connexion séparés
    (c'est à dire désactiver la traduction des adresses IPv6 au format IPv4),
    utilisez l'option --disable-v4-mapped du script
    configure. --disable-v4-mapped est
    utilisé par défaut sur FreeBSD, NetBSD, et OpenBSD.
    
  
    top
    

    

    Spécification du protocole avec Listen
    
    
    
    Dans la plupart des configurations, le second paramètre optionnel
    protocol de la directive Listen n'est pas obligatoire. S'il
    n'est pas spécifié, les protocoles par défaut
    sont https pour le port 443, et http pour
    tous les autres ports. Le protocole sert à déterminer quel module
    doit traiter une requête, et à appliquer les optimisations
    spécifiques au protocole via la directive AcceptFilter.
    

    
    Vous ne devez définir le protocole que si vous travaillez avec
    des ports non standards. Par exemple, pour travailler en
    https sur le port 8443 :
    

    
    Listen 192.170.2.1:8443 https
    

    
  
    top
    

    

    Qu'en est-il avec les serveurs virtuels
    
    

    
     La directive Listen n'implémente pas les serveurs virtuels.
    Elle indique simplement au serveur principal sur quels adresses et ports
    il doit écouter. Si aucune directive
    <VirtualHost>
    n'est présente, le serveur se comportera de la même façon pour toutes
    les requêtes acceptées. En revanche, la directive
    <VirtualHost>
    peut être utilisée pour provoquer une réaction différente du serveur
    pour un ou plusieurs adresses ou ports. Pour implémenter un serveur virtuel,
    on doit d'abord indiquer au serveur sur quels adresses et ports il doit écouter.
    Ensuite, une section
    <VirtualHost>
    doit être créée pour le couple adresse+port spécifié afin de définir le
    comportement de cet hôte virtuel. Notez que si la directive
    <VirtualHost>
    est définie pour une adresse et un port sur lesquels le serveur n'est pas censé
    écouter, cet hôte virtuel ne sera pas accessible.

Dynamic Shared Object (DSO) Support - Apache HTTP Server Version 2.4

    Dynamic Shared Object (DSO) Support

    The Apache HTTP Server is a modular program where the
    administrator can choose the functionality to include in the
    server by selecting a set of modules.
    Modules will be compiled as Dynamic Shared Objects (DSOs)
    that exist separately from the main httpd
    binary file. DSO modules may be compiled at the time the server
    is built, or they may be compiled and added at a later time
    using the Apache Extension Tool (apxs).
    
    
    Alternatively, the modules can be statically compiled into
    the httpd binary when the server is built.
    

    
    This document describes how to use DSO modules as well as
    the theory behind their use.

    Implementation
    


    Related ModulesRelated Directives
    

    
    The DSO support for loading individual Apache httpd modules is based
    on a module named mod_so which must be statically
    compiled into the Apache httpd core. It is the only module besides
    core which cannot be put into a DSO
    itself. Practically all other distributed Apache httpd modules will then
    be placed into a DSO. After a module is compiled into a DSO named
    mod_foo.so you can use mod_so's LoadModule directive in your
    httpd.conf file to load this module at server startup
    or restart.
    
    
    The DSO builds for individual modules can be disabled via
    configure's --enable-mods-static
    option as discussed in the install
    documentation.
    

    
    To simplify this creation of DSO files for Apache httpd modules
    (especially for third-party modules) a support program
    named apxs (APache
    eXtenSion) is available. It can be used to build DSO based
    modules outside of the Apache httpd source tree. The idea is
    simple: When installing Apache HTTP Server the configure's
    make install procedure installs the Apache httpd C
    header files and puts the platform-dependent compiler and
    linker flags for building DSO files into the apxs
    program. This way the user can use apxs to compile
    his Apache httpd module sources without the Apache httpd distribution
    source tree and without having to fiddle with the
    platform-dependent compiler and linker flags for DSO
    support.

    Usage Summary
    

    
    To give you an overview of the DSO features of Apache HTTP Server 2.x,
    here is a short and concise summary:
    

    
      
      
    1. 
        
      Build and install a distributed Apache httpd module, say
        mod_foo.c, into its own DSO
        mod_foo.so:
      


      
$ ./configure --prefix=/path/to/install --enable-foo
      
$ make install

      
      
      2. 

      
    2. 
      
      Configure Apache HTTP Server with all modules enabled. Only a basic
      set will be loaded during server startup. You can change the set of loaded
      modules by activating or deactivating the LoadModule directives in
      httpd.conf.
      


      
$ ./configure --enable-mods-shared=all
      
$ make install

      
      
      3. 

      
    3. 
      
      Some modules are only useful for developers and will not be build.
      when using the module set all. To build all available modules
      including developer modules use reallyall. In addition the
      LoadModule directives for all
      built modules can be activated via the configure option
      --enable-load-all-modules.
      


      
$ ./configure --enable-mods-shared=reallyall --enable-load-all-modules
      
$ make install

        Build and install a third-party Apache httpd module, say
        mod_foo.c, into its own DSO
        mod_foo.so outside of the Apache httpd
        source tree using apxs:


      
$ cd /path/to/3rdparty
      
$ apxs -cia mod_foo.c

      
      
      5. 
    
    

    
    In all cases, once the shared module is compiled, you must
    use a LoadModule
    directive in httpd.conf to tell Apache httpd to activate
    the module.
    

    
    See the apxs documentation for more details.

    Background
    

    
    On modern Unix derivatives there exists a mechanism
    called dynamic linking/loading of Dynamic Shared
    Objects (DSO) which provides a way to build a piece of
    program code in a special format for loading it at run-time
    into the address space of an executable program.
    

    
    This loading can usually be done in two ways: automatically
    by a system program called ld.so when an
    executable program is started or manually from within the
    executing program via a programmatic system interface to the
    Unix loader through the system calls
    dlopen()/dlsym().
    

    
    In the first way the DSO's are usually called shared
    libraries or DSO libraries and named
    libfoo.so or libfoo.so.1.2. They
    reside in a system directory (usually /usr/lib)
    and the link to the executable program is established at
    build-time by specifying -lfoo to the linker
    command. This hard-codes library references into the executable
    program file so that at start-time the Unix loader is able to
    locate libfoo.so in /usr/lib, in
    paths hard-coded via linker-options like -R or in
    paths configured via the environment variable
    LD_LIBRARY_PATH. It then resolves any (yet
    unresolved) symbols in the executable program which are
    available in the DSO.
    

    
    Symbols in the executable program are usually not referenced
    by the DSO (because it's a reusable library of general code)
    and hence no further resolving has to be done. The executable
    program has no need to do anything on its own to use the
    symbols from the DSO because the complete resolving is done by
    the Unix loader. (In fact, the code to invoke
    ld.so is part of the run-time startup code which
    is linked into every executable program which has been bound
    non-static). The advantage of dynamic loading of common library
    code is obvious: the library code needs to be stored only once,
    in a system library like libc.so, saving disk
    space for every program.
    

    
    In the second way the DSO's are usually called shared
    objects or DSO files and can be named with an
    arbitrary extension (although the canonical name is
    foo.so). These files usually stay inside a
    program-specific directory and there is no automatically
    established link to the executable program where they are used.
    Instead the executable program manually loads the DSO at
    run-time into its address space via dlopen(). At
    this time no resolving of symbols from the DSO for the
    executable program is done. But instead the Unix loader
    automatically resolves any (yet unresolved) symbols in the DSO
    from the set of symbols exported by the executable program and
    its already loaded DSO libraries (especially all symbols from
    the ubiquitous libc.so). This way the DSO gets
    knowledge of the executable program's symbol set as if it had
    been statically linked with it in the first place.
    

    
    Finally, to take advantage of the DSO's API the executable
    program has to resolve particular symbols from the DSO via
    dlsym() for later use inside dispatch tables
    etc. In other words: The executable program has to
    manually resolve every symbol it needs to be able to use it.
    The advantage of such a mechanism is that optional program
    parts need not be loaded (and thus do not spend memory) until
    they are needed by the program in question. When required,
    these program parts can be loaded dynamically to extend the
    base program's functionality.
    

    
    Although this DSO mechanism sounds straightforward there is
    at least one difficult step here: The resolving of symbols from
    the executable program for the DSO when using a DSO to extend a
    program (the second way). Why? Because "reverse resolving" DSO
    symbols from the executable program's symbol set is against the
    library design (where the library has no knowledge about the
    programs it is used by) and is neither available under all
    platforms nor standardized. In practice the executable
    program's global symbols are often not re-exported and thus not
    available for use in a DSO. Finding a way to force the linker
    to export all global symbols is the main problem one has to
    solve when using DSO for extending a program at run-time.
    

    
    The shared library approach is the typical one, because it
    is what the DSO mechanism was designed for, hence it is used
    for nearly all types of libraries the operating system
    provides.

    Advantages and Disadvantages
    

    
    The above DSO based features have the following
    advantages:
    

    
      
      
    • The server package is more flexible at run-time because
      the server process can be assembled at run-time via
      LoadModule
      httpd.conf configuration directives instead of
      configure options at build-time. For instance,
      this way one is able to run different server instances
      (standard & SSL version, minimalistic & dynamic
      version [mod_perl, mod_php], etc.) with only one Apache httpd
      installation.
      • 

      
    • The server package can be easily extended with
      third-party modules even after installation. This is
      a great benefit for vendor package maintainers, who can create
      an Apache httpd core package and additional packages containing
      extensions like PHP, mod_perl, mod_security, etc.
      • 

      
    • Easier Apache httpd module prototyping, because with the
      DSO/apxs pair you can both work outside the
      Apache httpd source tree and only need an apxs -i
      command followed by an apachectl restart to
      bring a new version of your currently developed module into
      the running Apache HTTP Server.
      • 
    
    

    
    DSO has the following disadvantages:
    

    
      
      
    • The server is approximately 20% slower at startup time
      because of the symbol resolving overhead the Unix loader now
      has to do.
      • 

      
    • The server is approximately 5% slower at execution time
      under some platforms, because position independent code (PIC)
      sometimes needs complicated assembler tricks for relative
      addressing, which are not necessarily as fast as absolute
      addressing.
      • 

      
    • Because DSO modules cannot be linked against other
      DSO-based libraries (ld -lfoo) on all platforms
      (for instance a.out-based platforms usually don't provide
      this functionality while ELF-based platforms do) you cannot
      use the DSO mechanism for all types of modules. Or in other
      words, modules compiled as DSO files are restricted to only
      use symbols from the Apache httpd core, from the C library
      (libc) and all other dynamic or static libraries
      used by the Apache httpd core, or from static library archives
      (libfoo.a) containing position independent code.
      The only chances to use other code is to either make sure the
      httpd core itself already contains a reference to it or
      loading the code yourself via dlopen().

    Diese Übersetzung ist möglicherweise
            nicht mehr aktuell. Bitte prüfen Sie die englische Version auf
            die neuesten Änderungen.
    

    
    Dieses Dokument beschreibt die Dateien, die zur Konfiguration des Apache
      HTTP Servers verwendet werden.
    
  
    


    top
    

    

    Hauptkonfigurationsdateien
    
    
    
    Referenzierte ModuleReferenzierte Direktiven
    

    
    Der Apache wird konfiguriert, indem Direktiven in einfache Textdateien
      eingetragen werden. Die Hauptkonfigurationsdatei heißt
      üblicherweise httpd.conf. Der Ablageort dieser Datei
      wird bei der Kompilierung festgelegt, kann jedoch mit der
      Befehlszeilenoption -f überschrieben werden. Durch
      Verwendung der Direktive  Include
      können außerdem weitere Konfigurationsdateien hinzugefügt
      werden. Zum Einfügen von mehreren Konfigurationsdateien können
      Platzhalter verwendet werden. Jede Direktive darf in jeder dieser
      Konfigurationsdateien angegeben werden. Änderungen in den
      Hauptkonfigurationsdateien werden vom Apache nur beim Start oder Neustart
      erkannt.
    

    
    Der Server liest auch eine Datei mit MIME-Dokumenttypen ein. Der
      Name dieser Datei wird durch die Direktive TypesConfig bestimmt. Die Voreinstellung
      ist mime.types.
    
  
    top
    

    

    Syntax der Konfigurationsdateien
    
    

    
    Die Konfigurationsdateien des Apache enthalten eine Direktive pro Zeile.
      Der Backslash "\" läßt sich als letztes Zeichen in einer Zeile
      dazu verwenden, die Fortsetzung der Direktive in der nächsten Zeile
      anzuzeigen. Es darf kein weiteres Zeichen oder Whitespace zwischen dem
      Backslash und dem Zeilenende folgen.
    

    
    In den Konfigurationsdateien wird bei den Direktiven nicht zwischen
      Groß- und Kleinschreibung unterschieden. Bei den Argumenten der
      Direktiven wird dagegen oftmals zwischen Groß- und Kleinschreibung
      differenziert. Zeilen, die mit dem Doppelkreuz "#" beginnen, werden als
      Kommentare betrachtet und ignoriert. Kommentare dürfen
      nicht am Ende einer Zeile nach der Direktive
      eingefügt werden. Leerzeilen und Whitespaces vor einer Direktive
      werden ignoriert. Dadurch lassen sich Direktiven zur besseren Lesbarbeit
      einrücken.
    

    
    Sie können die Syntax Ihrer Konfigurationsdateien auf Fehler
      prüfen, ohne den Server zu starten, indem Sie apachectl
        configtest oder die Befehlszeilenoption -t
      verwenden.
    
  
    top
    

    

    Module
    
    

    
    Referenzierte ModuleReferenzierte Direktiven
    

    
    Der Apache ist ein modularer Server. Das bedeutet, dass nur die abolute
      Grundfunktionalität im Kernserver enthalten ist. Weitergehende
      Fähigkeiten sind mittels Modulen verfügbar,
      die in den Apache geladen werden können. Standardmäßig
      wird bei der Kompilierung ein Satz von Basismodulen (Anm.d.Ü.: die so
        genannten Base-Module) in den Server eingebunden. Wenn der
      Server für die Verwendung von dynamisch
        ladbaren Modulen kompiliert wurde, dann können Module separat
      kompiliert und jederzeit mittels der Direktive LoadModule hinzugefügt werden.
      Andernfalls muss der Apache neu kompiliert werden, um Module
      hinzuzufügen oder zu entfernen. Konfigurationsanweisungen können
      abhängig vom Vorhandensein eines bestimmten Moduls eingesetzt werden,
      indem sie in einen <IfModule>-Block eingeschlossen werden.
    

    
    Um zu sehen, welche Module momentan in den Server einkompiliert sind,
      kann die Befehlszeilenoption -l verwendet werden.
    
  
    top
    

    

    Der Gültigkeitsbereich von Direktiven
    
    

    
    Referenzierte ModuleReferenzierte Direktiven
    

    
    Direktiven in den Hauptkonfigurationsdateien gelten für den
      gesamten Server. Wenn Sie die Konfiguration nur für einen Teil des
      Servers verändern möchten, können Sie den
      Gültigkeitsbereich der Direktiven beschränken, indem Sie diese
      in <Directory>-,
      <DirectoryMatch>-,
      <Files>-,
      <FilesMatch>-,
      <Location>- oder
      <LocationMatch>-Abschnitte eingefügen.
      Diese Abschnitte begrenzen die Anwendung der umschlossenen Direktiven
      auf bestimmte Pfade des Dateisystems oder auf
      bestimmte URLs. Sie können für eine fein abgestimmte
      Konfiguration auch ineinander verschachtelt werden.
    
    
    
    
    Der Apache besitzt die Fähigkeit, mehrere verschiedene Websites
      gleichzeitig zu bedienen. Dies wird virtuelles
        Hosten genannt. Direktiven können auch in ihrem
      Gültigkeitsgereich eingeschränkt werden, indem sie innerhalb
      eines <VirtualHost>-Abschnittes angegeben werden.
      Sie werden dann nur auf Anfragen für eine bestimmte Website
      angewendet.
    

    
    Obwohl die meisten Direktiven in jedem dieser Abschnitte platziert
      werden können, ergeben einige Direktiven in manchen Kontexten
      keinen Sinn. Direktiven zur Prozesssteuerung beispielsweise
      dürfen nur im Kontext des Hauptservers angegeben werden. Prüfen
      Sie den Kontext der
      Direktive, um herauszufinden, welche Direktiven in welche Abschnitte
      eingefügt werden können.  Weitere Informationen finden Sie unter
      "Wie Directory-, Location- und Files-Abschnitte
        arbeiten".

    .htaccess-Dateien
    
    

    
    Referenzierte ModuleReferenzierte Direktiven
    

    
    Der Apache ermöglicht die dezentrale Verwaltung der
      Konfiguration mittes spezieller Dateien innerhalb des
      Web-Verzeichnisbaums. Diese speziellen Dateien heißen
      gewöhnlich .htaccess, mit der Direktive AccessFileName kann jedoch auch ein anderer
      Name festgelegt werden. In .htaccess-Dateien angegebene
      Direktiven werden auf das Verzeichnis und dessen Unterverzeichnisse
      angewendet, in dem die Datei abgelegt ist. .htaccess-Dateien
      folgen der gleichen Syntax wie die Hauptkonfigurationsdateien. Da
      .htaccess-Dateien bei jeder Anfrage eingelesen werden,
      werden Änderungen in diesen Dateien sofort wirksam.
    

    
    Prüfen Sie den Kontext der Direktive, um
      herauszufinden, welche Direktiven in .htaccess-Dateien
      angegeben werden können. Darüber hinaus steuert der
      Serveradministrator mit der Einstellung der Direktive AllowOverride in den
      Hauptkonfigurationsdateien welche Direktiven in
      .htaccess-Dateien verwendet werden dürfen.
    

    
    Weitere Informationen über .htaccess-Dateien finden
      Sie in der .htaccess-Einführung.

    La conception modulaire du serveur HTTP Apache permet à l'administrateur
    de choisir les fonctionnalités à inclure dans le serveur en sélectionnant
    un certain nombre de modules. Les modules seront compilés en tant
    qu'Objets Dynamiques Partagés (Dynamic Shared Objects ou DSOs)
    qui mènent une existence séparée du fichier binaire principal
    httpd. Les modules DSO peuvent être compilés en
    même temps que le serveur, ou compilés et ajoutés ultérieurement via
    l'Outil des Extensions à Apache (Apache Extension Tool ou
    apxs).
    
    
    Les modules peuvent aussi être intégrés statiquement dans le
    binaire httpd lors de la compilation de ce
    dernier.
    

    
    Ce document décrit l'utilisation des modules DSO ainsi que les dessous
    de leur fonctionnement.

    Implémentation
    


    Modules ApparentésDirectives Apparentées
    

    
    Le support DSO pour le chargement de modules individuels d'Apache
    httpd est
    assuré par un module nommé mod_so qui doit être compilé
    statiquement dans le coeur d'Apache httpd. Il s'agit du seul module avec le
    module core à ne pas pouvoir être compilé en tant que
    module DSO lui-même. Pratiquement tous les autres modules d'Apache httpd
    distribués seront alors compilés en tant que modules DSO. Une fois
    compilé en tant que module DSO nommé mod_foo.so, un
    module peut être chargé en mémoire au
    démarrage ou redémarrage du serveur à l'aide de
    la directive LoadModule du module
    mod_so, placée
    dans votre fichier httpd.conf.
    
    
    La compilation en mode DSO peut être désactivée pour certains
    modules via l'option --enable-mods-static du script
    configure, comme expliqué dans la Documentation sur l'installation.
    

    
    Un utilitaire permet de simplifier la création de
    fichiers DSO pour les modules d'Apache httpd
    (particulièrement pour les modules tiers) ; il s'agit du programme nommé
    apxs (APache
    eXtenSion). On peut l'utiliser pour construire des modules de type
    DSO en dehors de l'arborescence des sources d'Apache httpd. L'idée est
    simple : à l'installation du serveur HTTP Apache, la procédure make install
    du script configure installe les fichiers d'en-têtes
    d'Apache httpd et positionne, pour la plateforme de compilation,  les drapeaux du compilateur et de
    l'éditeur de liens à l'intérieur du programme
    apxs, qui sera utilisé pour la construction de fichiers DSO.
    Il est ainsi possible d'utiliser le programme apxs
    pour compiler ses sources de modules Apache httpd sans avoir besoin de
    l'arborescence des sources de la distribution d'Apache, et sans avoir à
    régler les drapeaux du compilateur et de l'éditeur de liens pour le support DSO.

    Mode d'emploi succinct
    

    
    Afin que vous puissiez vous faire une idée des fonctionnalités DSO
    du serveur HTTP Apache 2.x, en voici un résumé court et concis :
    

    
      
      
    1. 
        
      Construire et installer un module Apache httpd faisant partie de la
	distribution, par exemple mod_foo.c,
	en tant que module DSO mod_foo.so :
      


      
$ ./configure --prefix=/chemin/vers/installation --enable-foo
      
$ make install

      
      
      2. 

      
    2. 
        
      Configure le serveur HTTP Apache avec tous les modules
	activés. Seul un jeu de modules de base sera chargé au
	démarrage du serveur. Vous pouvez modifier ce jeu de modules
	chargés au démarrage en activant ou désactivant les directives LoadModule correspondantes dans le
      fichier httpd.conf.
      


      
$ ./configure --enable-mods-shared=all
      
$ make install

      

        
      L'argument most de l'option
	--enable-modules indique que tous les modules
	non-expérimentaux ou qui ne sont pas là à titre d'exemple seront
	compilés.
      
      
      3. 

      
    3. 
      
      Certains modules ne sont utilisés que par les développeurs et
      ne seront pas compilés. Si vous voulez les utiliser, spécifiez
      l'option all. Pour compiler tous les modules disponibles,
      y compris les modules de développeurs, spécifiez l'option
      reallyall. En outre, la directive LoadModule peut être activée pour tous
      les modules compilés via l'option du script configure
      --enable-load-all-modules.
      


      
$ ./configure --enable-mods-shared=reallyall --enable-load-all-modules
      
$ make install

      
      
      4. 

      
    4. 
        Construire et installer un module Apache httpd tiers, par exemple
        mod_foo.c, en tant que module DSO
        mod_foo.so en dehors de l'arborescence des sources
	d'Apache httpd à l'aide du programme apxs :


      
$ cd /chemin/vers/module_tiers
      
$ apxs -cia mod_foo.c

      
      
      5. 
    
    

    
    Dans tous les cas, une fois le module partagé compilé, vous devez
    ajouter une directive LoadModule
    dans le fichier httpd.conf pour qu'Apache httpd active le module.
    

    
    Voir la documentation sur apxs
    pour plus de détails.

    Les dessous du fonctionnement des DSO
    

    
    Les clônes modernes d'UNIX proposent un mécanisme
    appelé édition de liens et chargement dynamiques d'
    Objets Dynamiques Partagés (DSO), qui permet de construire un
    morceau de programme dans un format spécial pour le rendre chargeable
    à l'exécution dans l'espace d'adressage d'un programme exécutable.
    

    
    Ce chargement peut s'effectuer de deux manières : automatiquement par
    un programme système appelé ld.so quand un programme
    exécutable est démarré, ou manuellement à partir du programme en cours
    d'exécution via sa propre interface système vers le chargeur Unix à l'aide
    des appels système dlopen()/dlsym().
    

    
    Dans la première méthode, les DSO sont en général appelés
    bibliothèques partagées ou encore bibliothèques DSO, et
    possèdent des noms du style
    libfoo.so ou libfoo.so.1.2. Ils résident dans un
    répertoire système (en général /usr/lib)
    et le lien avec le programme exécutable est établi à la compilation en
    ajoutant -lfoo à la commande de l'éditeur de liens. Les
    références à la bibliothèque sont ainsi codées en dur dans le fichier du
    programme exécutable de façon à ce qu'au démarrage du programme, le
    chargeur Unix soit capable de localiser libfoo.so dans
    /usr/lib, dans des chemins codés en dur à l'aide d'options de
    l'éditeur de liens comme -R ou dans des chemins définis par la
    variable d'environnement
    LD_LIBRARY_PATH. Le chargeur peut dès lors résoudre tous les symboles
    (jusque là non encore résolus) du DSO dans le programme exécutable.
    

    
    Les symboles du programme exécutable ne sont en général pas
    référencés par le DSO (car c'est une bibliothèque de code à usage général
    et réutilisable),
    et ainsi aucune résolution supplémentaire n'est nécessaire. De son côté,
    le programme exécutable ne doit accomplir aucune action particulière
    pour utiliser les
    symboles du DSO car toutes les résolutions sont effectuées par le chargeur
    Unix. En fait, le code permettant d'invoquer
    ld.so fait partie du code de démarrage pour l'exécution qui
    est lié dans tout programme exécutable non statiquement lié.
    L'avantage du chargement dynamique du code d'une bibliothèque partagée est
    évident : le code de la bibliothèque ne doit être stocké qu'une seule fois
    dans une bibliothèque système telle que libc.so, ce qui permet
    d'économiser de l'espace disque pour les autres programmes.
    

    
    Dans la seconde méthode, les DSO sont en général appelés objets
    partagés ou fichiers DSO, et peuvent être nommés avec
    l'extension de son choix (bien que le nom conseillé soit du style
    foo.so). Ces fichiers résident en général dans un répertoire
    spécifique à un programme, et aucun lien n'est automatiquement établi avec
    le programme exécutable dans lequel ils sont utilisés.
    Le programme exécutable charge manuellement le DSO à l'exécution dans son
    espace d'adressage à l'aide de l'appel système dlopen().
    A ce moment, aucune résolution de symboles du DSO n'est effectuée pour le
    programme exécutable. Par contre le chargeur Unix
    résoud automatiquement tout symbole du DSO (non encore résolu)
    faisant partie de l'ensemble de symboles exporté par le programme
    exécutable et ses bibliothèques DSO déjà chargées (et en particulier tous
    les symboles de la bibliothèque à tout faire libc.so).
    De cette façon, le DSO prend connaissance de l'ensemble de symboles du
    programme exécutable comme s'il avait été lié statiquement avec lui
    auparavant.
    

    
    Finalement, pour tirer profit de l'API des DSO, le programme exécutable
    doit résoudre certains symboles du DSO à l'aide de l'appel système
    dlsym() pour une utilisation ultérieure dans les tables de
    distribution, etc... En d'autres termes, le programme exécutable doit
    résoudre manuellement tous les symboles dont il a besoin pour pouvoir les
    utiliser.
    Avantage d'un tel mécanisme : les modules optionnels du programme n'ont pas
    besoin d'être chargés (et ne gaspillent donc pas de ressources mémoire)
    tant qu'il ne sont pas nécessaires au programme en question. Si nécessaire,
    ces modules peuvent être chargés dynamiquement afin d'étendre les
    fonctionnalités de base du programme.
    

    
    Bien que ce mécanisme DSO paraisse évident, il comporte au moins une
    étape difficile : la résolution des symboles depuis le programme exécutable
    pour le DSO lorsqu'on utilise un DSO pour étendre les fonctionnalités d'un
    programme (la seconde méthode). Pourquoi ? Parce que la "résolution
    inverse" des symboles DSO à partir du jeu de symboles du programme
    exécutable dépend de la conception de la bibliothèque (la bibliothèque n'a
    aucune information sur le programme qui l'utilise) et n'est ni standardisée
    ni disponible sur toutes les plateformes. En pratique, les symboles globaux
    du programme exécutable ne sont en général pas réexportés et donc
    indisponibles pour l'utilisation dans un DSO. Trouver une méthode pour
    forcer l'éditeur de liens à exporter tous les symboles globaux est le
    principal problème que l'on doit résoudre lorsqu'on utilise un DSO pour
    étendre les fonctionnalités d'un programme au moment de son exécution.
    

    
    L'approche des bibliothèques partagées est la plus courante, parce que
    c'est dans cette optique que le mécanisme DSO a été conçu ; c'est cette
    approche qui est ainsi
    utilisée par pratiquement tous les types de bibliothèques que fournit le
    système d'exploitation.
    


    top
    

    

    Avantages et inconvénients
    

    
    Les fonctionnalités ci-dessus basées sur les DSO présentent les
    avantages suivants :
    

    
      
      
    • Le paquetage du serveur est plus flexible à l'exécution car le
      processus serveur peut être assemblé à l'exécution via la
      directive LoadModule du fichier de
      configuration httpd.conf plutôt que par des options du script
      configure à la compilation. Par exemple,
      on peut ainsi exécuter différentes instances du serveur
      (standard et version SSL, version minimale et version dynamique
      [mod_perl, mod_php], etc...) à partir d'une seule installation
      d'Apache httpd.
      • 

      
    • Le paquetage du serveur peut être facilement étendu avec des modules
      tiers, même après l'installation. Ceci présente un gros
      avantage pour les mainteneurs de paquetages destinés aux distributions,
      car ils peuvent créer un paquetage Apache httpd de base, et des paquetages
      additionnels contenant des extensions telles que PHP, mod_perl, mod_fastcgi,
      etc...
      • 

      
    • Une facilité de prototypage des modules Apache httpd, car la paire
      DSO/apxs vous permet d'une part de travailler en
      dehors de l'arborescence des sources d'Apache httpd, et d'autre part de n'avoir
      besoin que de la commande apxs -i
      suivie d'un apachectl restart pour introduire une nouvelle
      version de votre module fraîchement développé dans le serveur HTTP Apache
      en cours d'exécution.
      • 
    
    

    
    Inconvénients des DSO :
    

    
      
      
    • Le serveur est environ 20 % plus lent au démarrage
      à cause des résolutions de symboles supplémentaires que le chargeur
      Unix doit effectuer.
      • 

      
    • Le serveur est environ 5 % plus lent à l'exécution
      sur certaines plates-formes, car le code indépendant de la position (PIC)
      nécessite parfois des manipulations compliquées en assembleur pour
      l'adressage relatif qui ne sont pas toujours aussi rapides que celles
      que permet l'adressage absolu.
      • 

      
    • Comme les modules DSO ne peuvent pas être liés avec d'autres
      bibliothèques basées sur DSO (ld -lfoo) sur toutes les
      plates-formes
      (par exemple, les plates-formes basées sur a.out ne fournissent en
      général pas cette fonctionnalité alors que les plates-formes basées sur
      ELF le font), vous ne pouvez pas utiliser le mécanisme DSO pour tous les
      types de modules. Ou en d'autres termes, les modules compilés comme
      fichiers DSO sont contraints de n'utiliser que les symboles du coeur
      d'Apache httpd, de la bibliothèque C
      (libc) et toutes autres bibliothèques statiques ou
      dynamiques utilisées par le coeur d'Apache httpd, ou d'archives statiques
      (libfoo.a) contenant du code indépendant de la
      position (PIC).
      Il y a deux solutions pour utiliser un autre type de code : soit le
      coeur d'Apache httpd contient déjà lui-même une référence au code, soit vous
      chargez le code vous-même via dlopen().

    Environment Variables in Apache
    

    

    Available Languages:  en  |

 tr 
    

    

    
    There are two kinds of environment variables that affect
    the Apache HTTP Server.
    

    
    First, there are the environment variables controlled by
    the underlying operating system.  These are set before the
    server starts.  They can be used in expansions in configuration
    files, and can optionally be passed to CGI scripts and SSI
    using the PassEnv directive.
    

    
    Second, the Apache HTTP Server provides a mechanism for storing
    information in named variables that are also called environment
    variables. This information can be used to control various
    operations such as logging or access control. The variables are
    also used as a mechanism to communicate with external programs
    such as CGI scripts. This document discusses different ways to
    manipulate and use these variables.
    

    
    Although these variables are referred to as environment
    variables, they are not the same as the environment
    variables controlled by the underlying operating system.
    Instead, these variables are stored and manipulated in an
    internal Apache structure. They only become actual operating
    system environment variables when they are provided to CGI
    scripts and Server Side Include scripts. If you wish to
    manipulate the operating system environment under which the
    server itself runs, you must use the standard environment
    manipulation mechanisms provided by your operating system
    shell.

    Setting Environment Variables
    
    
    
    Related ModulesRelated Directives
    

    
    Basic Environment Manipulation
    
        

        
    The most basic way to set an environment variable in Apache
        is using the unconditional SetEnv directive. Variables may also be passed from
        the environment of the shell which started the server using the
        PassEnv directive.
    

    
    
    Conditional Per-Request Settings
    
        

        
    For additional flexibility, the directives provided by
        mod_setenvif allow environment variables to be set
        on a per-request basis, conditional on characteristics of particular
        requests. For example, a variable could be set only when a
        specific browser (User-Agent) is making a request, or only when
        a specific Referer [sic] header is found. Even more flexibility
        is available through the mod_rewrite's RewriteRule which uses the
        [E=...] option to set environment variables.
    

    
    
    Unique Identifiers
    
        

        
    Finally, mod_unique_id sets the environment
        variable UNIQUE_ID for each request to a value which is
        guaranteed to be unique across "all" requests under very
        specific conditions.
    

    
    
    Standard CGI Variables
    
        

        
    In addition to all environment variables set within the
        Apache configuration and passed from the shell, CGI scripts and
        SSI pages are provided with a set of environment variables
        containing meta-information about the request as required by
	the CGI
        specification.
    

    
    
    Some Caveats
    
        

        
      
          
    • It is not possible to override or change the standard CGI
          variables using the environment manipulation directives.
      • 

          
    • When suexec is used to launch
          CGI scripts, the environment will be cleaned down to a set of
          safe variables before CGI scripts are launched. The
          list of safe variables is defined at compile-time in
          suexec.c.
      • 

          
    • For portability reasons, the names of environment
          variables may contain only letters, numbers, and the
          underscore character. In addition, the first character may
          not be a number. Characters which do not match this
          restriction will be replaced by an underscore when passed to
          CGI scripts and SSI pages.
      • 

          
    • A special case are HTTP headers which are passed to CGI
          scripts and the like via environment variables (see below).
          They are converted to uppercase and only dashes are replaced with
          underscores; if the header contains any other (invalid) character,
          the whole header is silently dropped. See 
          below for a workaround.
      • 

          
    • The SetEnv directive runs
          late during request processing meaning that directives such as
          SetEnvIf and RewriteCond will not see the
          variables set with it.
      • 

          
    • When the server looks up a path via an internal
          subrequest such as looking
          for a DirectoryIndex
          or generating a directory listing with mod_autoindex,
          per-request environment variables are not inherited in the 
          subrequest. Additionally, 
          SetEnvIf directives
          are not separately evaluated in the subrequest due to the API phases
           mod_setenvif takes action in.

    Using Environment Variables
    
    

    
    Related ModulesRelated Directives
    

    
    CGI Scripts
    
        

        
    One of the primary uses of environment variables is to
        communicate information to CGI scripts. As discussed above, the
        environment passed to CGI scripts includes standard
        meta-information about the request in addition to any variables
        set within the Apache configuration. For more details, see the
        CGI tutorial.
    

    
    
    SSI Pages
    
        

        
    Server-parsed (SSI) documents processed by
        mod_include's
        INCLUDES filter can print environment variables
        using the echo element, and can use environment
        variables in flow control elements to makes parts of a page
        conditional on characteristics of a request. Apache also
        provides SSI pages with the standard CGI environment variables
        as discussed above. For more details, see the SSI tutorial.
    

    
    
    Access Control
    
        

        
    Access to the server can be controlled based on
        environment variables using the Require env
        and Require not env directives. In combination with
        SetEnvIf, this
        allows for flexible control of access to the server based on
        characteristics of the client. For example, you can use these
        directives to deny access to a particular browser (User-Agent).
        
    

    
    
    Conditional Logging
    
        

        
    Environment variables can be logged in the access log using
        the LogFormat
        option %e. In addition, the decision on whether
        or not to log requests can be made based on the status of
        environment variables using the conditional form of the
        CustomLog
        directive. In combination with SetEnvIf this allows for flexible control of which
        requests are logged. For example, you can choose not to log
        requests for filenames ending in gif, or you can
        choose to only log requests from clients which are outside your
        subnet.
    

    
    
    Conditional Response Headers
    
        

        
    The Header
        directive can use the presence or
        absence of an environment variable to determine whether or not
        a certain HTTP header will be placed in the response to the
        client. This allows, for example, a certain response header to
        be sent only if a corresponding header is received in the
        request from the client.
    

    

    
    External Filter Activation
    
        

        
    External filters configured by mod_ext_filter
        using the ExtFilterDefine directive can
        by activated conditional on an environment variable using the
        disableenv= and enableenv= options.
    
    

    
    URL Rewriting
    
        

        
    The %{ENV:variable} form of
        TestString in the RewriteCond allows mod_rewrite's rewrite
        engine to make decisions conditional on environment variables.
        Note that the variables accessible in mod_rewrite
        without the ENV: prefix are not actually environment
        variables. Rather, they are variables special to
        mod_rewrite which cannot be accessed from other
        modules.

    Special Purpose Environment Variables
    
    

        
    Interoperability problems have led to the introduction of
        mechanisms to modify the way Apache behaves when talking to
        particular clients. To make these mechanisms as flexible as
        possible, they are invoked by defining environment variables,
        typically with BrowserMatch, though SetEnv and  PassEnv could also be used, for example.
    

    
    downgrade-1.0
    
        

        
    This forces the request to be treated as a HTTP/1.0 request
        even if it was in a later dialect.
    

    
    
    force-gzip
    
        
          
    If you have the DEFLATE filter activated, this
          environment variable will ignore the accept-encoding setting of
          your browser and will send compressed output unconditionally.
    
    
    
    force-no-vary
    
        

        
    This causes any Vary fields to be removed from
        the response header before it is sent back to the client. Some
        clients don't interpret this field correctly; setting this
        variable can work around this problem. Setting this variable
        also implies force-response-1.0.
    

    
    
    force-response-1.0
    
        

      
    This forces an HTTP/1.0 response to clients making an HTTP/1.0
      request. It was originally
      implemented as a result of a problem with AOL's proxies. Some
      HTTP/1.0 clients may not behave correctly when given an HTTP/1.1
      response, and this can be used to interoperate with them.
    

    

    
    gzip-only-text/html
    
        

        
    When set to a value of "1", this variable disables the
        DEFLATE output filter provided by
        mod_deflate for content-types other than
        text/html. If you'd rather
        use statically compressed files, mod_negotiation
        evaluates the variable as well (not only for gzip, but for all
        encodings that differ from "identity").
    
    

    
    no-gzip
    

        
    When set, the DEFLATE filter of
        mod_deflate will be turned off and
        mod_negotiation will refuse to deliver encoded
        resources.
    

    

    
    no-cache
    
        
    Available in versions 2.2.12 and later
    

        
    When set, mod_cache will not save an otherwise
        cacheable response.  This environment variable does not influence
        whether a response already in the cache will be served for the current
        request.
    

    

    
    nokeepalive
    
        

        
    This disables KeepAlive
        when set.
    

    

    
    prefer-language
    

        
    This influences mod_negotiation's behaviour. If
        it contains a language tag (such as en, ja
        or x-klingon), mod_negotiation tries
        to deliver a variant with that language. If there's no such variant,
        the normal negotiation process
        applies.
    

    

    
    redirect-carefully
    
        

        
    This forces the server to be more careful when sending a redirect
        to the client.  This is typically used when a client has a known
        problem handling redirects.  This was originally implemented as a
        result of a problem with Microsoft's WebFolders software which has
        a problem handling redirects on directory resources via DAV
        methods.
    

    

   
    suppress-error-charset
    
       

    
    Available in versions after 2.0.54
    

    
    When Apache issues a redirect in response to a client request,
    the response includes some actual text to be displayed in case
    the client can't (or doesn't) automatically follow the redirection.
    Apache ordinarily labels this text according to the character set
    which it uses, which is ISO-8859-1.
    

    
     However, if the redirection is to a page that uses a different
    character set, some broken browser versions will try to use the
    character set from the redirection text rather than the actual page.
    This can result in Greek, for instance, being incorrectly rendered.
    

    
    Setting this environment variable causes Apache to omit the character
    set for the redirection text, and these broken browsers will then correctly
    use that of the destination page.
    

    
    
      
    Security note
    

      
    Sending error pages without a specified character set may
      allow a cross-site-scripting attack for existing browsers (MSIE)
      which do not follow the HTTP/1.1 specification and attempt to
      "guess" the character set from the content.  Such browsers can
      be easily fooled into using the UTF-7 character set, and UTF-7
      content from input data (such as the request-URI) will not be
      escaped by the usual escaping mechanisms designed to prevent
      cross-site-scripting attacks.
    
    
    

   

   
    force-proxy-request-1.0, proxy-nokeepalive, proxy-sendchunked,
   proxy-sendcl, proxy-chain-auth, proxy-interim-response, proxy-initial-not-pooled
    

   
    These directives alter the protocol behavior of
   mod_proxy.  See the mod_proxy and mod_proxy_http
   documentation for more details.
    
   

  
    top
    

    

    Examples
    
    

    
    Passing broken headers to CGI scripts
    
      

      
    Starting with version 2.4, Apache is more strict about how HTTP
      headers are converted to environment variables in mod_cgi
       and other modules:  Previously any invalid characters
      in header names were simply translated to underscores.  This allowed
      for some potential cross-site-scripting attacks via header injection
      (see 
      Unusual Web Bugs, slide 19/20).
    

      
    If you have to support a client which sends broken headers and
      which can't be fixed, a simple workaround involving mod_setenvif
       and mod_headers allows you to still accept
      these headers:
    


    #
# The following works around a client sending a broken Accept_Encoding
# header.
#
SetEnvIfNoCase ^Accept.Encoding$ ^(.*)$ fix_accept_encoding=$1
RequestHeader set Accept-Encoding %{fix_accept_encoding}e env=fix_accept_encoding
    


    

    
    Changing protocol behavior with misbehaving clients
    
        

        
    Earlier versions recommended that the following lines be included in
        httpd.conf to deal with known client problems.  Since the affected clients
        are no longer seen in the wild, this configuration is likely no-longer
        necessary.
    

    #
# The following directives modify normal HTTP response behavior.
# The first directive disables keepalive for Netscape 2.x and browsers that
# spoof it. There are known problems with these browser implementations.
# The second directive is for Microsoft Internet Explorer 4.0b2
# which has a broken HTTP/1.1 implementation and does not properly
# support keepalive when it is used on 301 or 302 (redirect) responses.
#
BrowserMatch "Mozilla/2" nokeepalive
BrowserMatch "MSIE 4\.0b2;" nokeepalive downgrade-1.0 force-response-1.0

#
# The following directive disables HTTP/1.1 responses to browsers which
# are in violation of the HTTP/1.0 spec by not being able to understand a
# basic 1.1 response.
#
BrowserMatch "RealPlayer 4\.0" force-response-1.0
BrowserMatch "Java/1\.0" force-response-1.0
BrowserMatch "JDK/1\.0" force-response-1.0
    


    
    
    Do not log requests for images in the access log
    
        

        
    This example keeps requests for images from appearing in the
        access log. It can be easily modified to prevent logging of
        particular directories, or to prevent logging of requests
        coming from particular hosts.
    

        
    SetEnvIf Request_URI \.gif image-request
SetEnvIf Request_URI \.jpg image-request
SetEnvIf Request_URI \.png image-request
CustomLog "logs/access_log" common env=!image-request
    


    
    
    Prevent "Image Theft"
    
        

        
    This example shows how to keep people not on your server
        from using images on your server as inline-images on their
        pages. This is not a recommended configuration, but it can work
        in limited circumstances. We assume that all your images are in
        a directory called /web/images.
    

        
    SetEnvIf Referer "^http://www\.example\.com/" local_referal
# Allow browsers that do not send Referer info
SetEnvIf Referer "^$" local_referal
<Directory "/web/images">
    Require env local_referal
</Directory>
    


        
    For more information about this technique, see the
        "Keeping Your Images from Adorning Other Sites"
        tutorial on ServerWatch.

    Ce document décrit quelques uns des changements principaux entre
     les versions 2.0 et 2.2 du serveur HTTP Apache. Pour les
     nouvelles fonctionnalités ajoutées depuis la version 1.3, se
     référer au document
     2.0 new features.
    

    


    top
    

    

    Améliorations du système de base
    
    
    
    

      
    Authn/Authz
    
      
    Les modules d'authentification et d'autorisation intégrés
	ont été refondus. Le nouveau module
	mod_authn_alias (supprimé dans la version 2.3/2.4) permet de
	simplifier considérablement certaines configurations d'authentification.
          Voir modification des noms de modules,
	  et
	  les changements pour le développeur
	  pour plus d'informations sur les conséquences de ces
	  changements pour les utilisateurs et les développeurs de
	  modules.
    

      
    Mise en cache
    
      
    mod_cache, mod_cache_disk, et
          mod_mem_cache (supprimés dans la version 2.3/2.4) ont subi de nombreuses
	  modifications, et l'on considère qu'ils ont maintenant atteint
	  un degré de qualité suffisant pour leur mise en production. Le programme
	  htcacheclean a été ajouté afin de rendre
	  plus propre la configuration du module
	  mod_cache_disk.
    

      
    Configuration
    
      
    L'agencement de la configuration par défaut a été simplifié
      	et modularisé. Les portions de configuration qui peuvent être
	utilisées pour activer des fonctionnalités courantes sont
	maintenant intégrées à Apache, et peuvent être facilement
	ajoutées à la configuration principale du serveur.
    

      
    Arrêt en douceur
    
      
    Les modules MPM prefork,
        worker et event permettent
	maintenant l'arrêt en douceur de httpd
          au moyen du signal
          graceful-stop.
	  La directive GracefulShutdownTimeout a été ajoutée dans le but
	  de spécifier un délai optionnel, après lequel
          httpd s'arrêtera quel que soit le statut
          des requêtes en cours.
    

      
    Mise en oeuvre du proxy
    
      
    Le nouveau module mod_proxy_balancer fournit
          des services de répartition de charge (load balancing) pour le
	  module mod_proxy.
          Le nouveau module mod_proxy_ajp ajoute le
	  support pour le
          Protocole JServ de Apache version 1.3 qu'utilise
          Apache Tomcat.
    

      
    Mise à jour de la bibliothèque des expressions rationnelles
    
      
    La version 5.0 de la
          Perl Compatible Regular Expression
          Library (PCRE) est maintenant disponible.
	  httpd peut être configuré pour utiliser une
	  PCRE choisie en passant l'option --with-pcre au
	  script configure.
    

      
    Filtrage intelligent
    
      
    Le module mod_filter permet la configuration
          dynamique de la chaîne de filtrage en sortie. Il permet
	  d'insérer des filtres conditionnels basés sur toute
	  requête, en-tête de réponse ou variable
	  d'environnement, et fait table rase des problèmes de dépendances
	  et d'ordonnancement rencontrés avec l'architecture 2.0.
    

      
    Support des gros fichiers
    
      
    httpd supporte maintenant les fichiers d'une taille supérieure
      à 2GB sur les systèmes 32 bits UNIX modernes.  Le support des
      corps de requête d'une taille supérieure à 2GB a aussi été
      ajouté.
    

      
    Module MPM Event
    
      
    Le module MPM event utilise un thread séparé
      	pour gérer les requêtes "Keep alive" et accepter des connexions.
	Les requêtes "Keep alive" requéraient traditionnellement un
	processus httpd dédié pour leur gestion. Ce processus dédié
	ne pouvait plus être réutilisé jusqu'à ce que le délai "Keep Alive"
          soit écoulé.
    

      
    Support des bases de données SQL
    
      
    Le module mod_dbd, associé à l'environnement
      	apr_dbd, fournit le support SQL direct aux modules
	qui en ont besoin.  Supporte la mise en commun des connexions
          dans les modules MPM threadés.
    

    
    
  
    top
    

    

    Améliorations des modules
    
    
    
    
      
    Authn/Authz
    
      
    Les modules du répertoire aaa ont été renommés et fournissent
          un support amélioré pour la méthode d'authentification digest.  Par exemple, mod_auth
          est maintenant scindé en deux modules : mod_auth_basic et
          mod_authn_file; mod_auth_dbm s'appelle maintenant
          mod_authn_dbm; mod_access a été renommé en
          mod_authz_host.  Est également apparu le nouveau module
          mod_authn_alias (supprimé dans la version 2.3/2.4) qui simplifie
          certaines configurations d'authentification.
      
    

      
    mod_authnz_ldap
    
      
    Ce module est un portage de la version 2.0 du module
          mod_auth_ldap vers la version 2.2 du framework
	  Authn/Authz.
	  Les nouvelles fonctionnalités comprennent l'utilisation des valeurs
	  d'attributs LDAP et des filtres de recherche avancés dans la
          directive Require.
    

      
    mod_authz_owner
    
	
    Un nouveau module qui autorise l'accès à un fichier
	en fonction de son propriétaire dans le système de
	fichiers
    

	
    mod_version
    
	
    Un nouveau module qui permet d'activer des blocs de
	configuration en fonction de la version du serveur en cours
	d'exécution.
    

      
    mod_info
    
      
    Un nouvel argument ?config a été ajouté, qui permettra d'afficher
          les directives de configuration telles qu'elles sont interprétées
	  par Apache, y compris le nom de fichier et le numéro de ligne.
	  Le module montre aussi l'ordre des points d'entrée de traitement d'une
	  requête (request hooks) ainsi que des informations de construction
	  supplémentaires, d'une manière similaire à httpd -V.
    

      
    mod_ssl
    
      
      
    Le support de la RFC 2817 a été ajouté, ce qui permet de passer d'une
	connexion en clair au chiffrement TLS.
    

      
    mod_imagemap
    
      
    mod_imap a été renommé en mod_imagemap afin
      d'éviter une confusion pour les utilisateurs.
    
    
    

  
    top
    

    

    Améliorations des programmes
    
    
    
    
      
    httpd
    
      
    Une nouvelle option de ligne de commande -M
     a été ajoutée, qui fournit la liste de tous les modules chargés
     en fonction de la configuration réelle. À la différence de l'option
     -l, cette liste inclut les Objets Dynamiques Partagés
     (DSOs) chargés par l'intermédiaire du module
     mod_so.
    
      
    httxt2dbm
    
      
    Un nouveau programme servant à générer des fichiers dbm à partir
      d'une source au format texte, à utiliser avec la directive
      RewriteMap
          et le type de mise en correspondance dbm.
    
    
    
  
    top
    

    

    Changements pour le développeur de module
    
    
    
    
      
    APR 1.0 API
    

      
    Apache 2.2 utilise l'API APR 1.0.  Toutes les fonctions et
      symboles obsolètes ont été supprimés du code de APR et
          APR-Util. Pour plus de détails, consultez le
          site web d'APR.
    

      
    Authn/Authz
    
      
    Les modules d'authentification et d'autorisation intégrés ont
          été renommés de la manière suivante:
          
      
          
    • mod_auth_*  -> Modules qui implémentent un mécanisme
	  	d'authentification HTTP
      • 
          
    • mod_authn_* -> Modules qui fournissent un dispositif
	  	d'authentification en arrière-plan
      • 
          
    • mod_authz_* -> Modules qui implémentent l'autorisation (ou l'accès)
      • 
          
    • mod_authnz_* -> Modules qui implémentent à la fois
	  l'authentification & l'autorisation
      • 
          
    
	  L'organisation des méthodes d'authentification a également été revue, ce qui va simplifier
	  grandement l'ajout de nouvelles méthodes d'authentification.
    

      
    Journalisation des erreurs de connexion
    

      
    Une nouvelle fonction a été ajoutée, ap_log_cerror,
      afin de pouvoir enregistrer les erreurs qui surviennent au cours de
      la connexion du client.  Une fois enregistré, le message inclut l'adresse IP du client.
    

      
    Ajout d'une portion de code pour la vérification de la configuration
    

      
    Un nouvel élément de traitement a été ajouté, test_config,
      afin d'aider les modules qui ne veulent exécuter un code spécial
      que si l'utilisateur passe le paramètre -t à
      httpd.
    

      
    Définition de la taille de la pile pour les modules MPM en processus légers
    

      
    Une nouvelle directive a été ajoutée, ThreadStackSize
     afin de définir la taille de la pile pour tous les modules MPM en processus légers (modules threadés).
     Ceci s'avère nécessaire pour certains modules tiers sur des plateformes
     dont la taille de la pile des threads par défaut est
     trop petite.
    

      
    Gestion de protocole pour les filtres en sortie
    

      
    Par le passé, chaque filtre devait s'assurer que les en-têtes de
      réponse corrects étaient générés dans la mesure où il les affectait.
      Les filtres peuvent maintenant déléguer la gestion courante du
      protocole au module
          mod_filter, à l'aide des appels
          ap_register_output_filter_protocol ou
          ap_filter_protocol.
    

      
    Ajout d'un élément de traitement pour le processus père (monitor hook)
    
      
    Ce nouvel élément de traitement permet aux modules de lancer
      des jobs réguliers/planifiés au niveau du processus père
      (root).
    

      
    Modifications de l'API de traitement des expressions rationnelles
    

      
    Le fichier d'en-tête pcreposix.h n'est plus disponible ;
      il a été remplacé par le nouveau fichier
      d'en-tête ap_regex.h.  L'implémentation
      POSIX.2 regex.h exposée dans l'ancien fichier d'en-tête
      est maintenant disponible dans l'espace de nommage ap_
      depuis ap_regex.h.  Les appels à regcomp,
      regexec, etc... peuvent être remplacés par des appels à
      ap_regcomp, ap_regexec.
    

      
    Cadre d'application DBD (API pour base de données SQL)
    

      
    Avec Apache 1.x et 2.0, les modules nécessitant un processus
      SQL d'arrière-plan devaient s'en charger eux-mêmes.  En dehors du fait
      de réinventer la roue, ceci peut s'avérer très inefficace, par
      exemple lorsque plusieurs modules maintiennent chacun leurs
      propres connexions.
    
      
    Apache 2.1 et supérieur fournissent l'API ap_dbd qui
      permet la gestion des connexions à la base de données (y compris
      les stratégies optimisées pour les modules MPM threadés
      et non threadés), tandis que APR 1.2 et supérieur fournissent
      l'API apr_dbd qui permet l'interaction avec la
      base de données.
    
      
    Les nouveaux modules DEVRAIENT désormais utiliser ces APIs pour
      toutes les opérations liées aux bases de données SQL.
      De même, les applications existantes DEVRAIENT être mises à jour
      lorsque c'est possible, que ce soit de manière transparente ou sous forme
      d'une option recommandée à leurs utilisateurs.

    Filtros en Apache 2
    
      
      
    Módulos RelacionadosDirectivas Relacionadas
    

        
    La cadena de filtrado está disponible en Apache 2.0 y superiores.
        Un filtro es un proceso que se aplica a los datos que
        se reciben o se envían por el servidor. Los datos enviados
        por los clientes al servidor son procesados por filtros de
        entrada mientras que los datos enviados por el servidor se
        procesan por los filtros de salida. A los datos se les
        pueden aplicar varios filtros, y el orden en que se aplica cada
        filtro puede especificarse explícitamente.
        Todo este proceso es independiente de las tradicionales fase de
        peticiones
    
        
    
      Filters can be chained, in a Data Axis orthogonal to request processing
      
    
      
    Algunos ejemplos de filtrado en la distribución estándar de Apache son:
    
      
        
    Los filtros se usan internamente por Apache para llevar a cabo
        funciones tales como chunking y servir peticiones de
        byte-range. Además, los módulos contienen filtros que se
        pueden seleccionar usando directivas de configuración al
        iniciar el servidor.
    

        
    Una mayor amplitud de aplicaciones son implementadas con módulos de 
        filtros de terceros que estan disponibles en modules.apache.org y en otros lados.
        algunos de ellos son:
    

        
      
      
    • Procesamiento y reescritura de HTML y XML.
      • 
      
    • Transformaciones de XSLT y XIncludes.
      • 
      
    • Soporte de espacios de nombres en XML.
      • 
      
    • Manipulación de carga de archivos y decodificación de los 
        formularios HTML.
      • 
      
    • Procesamiento de imágenes.
      • 
      
    • Protección de aplicaciones vulnerables, tales como scripts PHP
      • 
      
    • Edición de texto de búsqueda y remplazo.

    Filtrado Inteligente
    
      
        
    
        Smart filtering applies different filter providers according to the state of request processing
        
    
        
    mod_filter, incluido en Apache 2.1 y posterior,
        habilita la cadena de filtrado para ser configurada dinámicamente en
        tiempo de ejecución. Así, por ejemplo, usted puede configurar un 
        proxy para que reescriba HTML con un filtro de HTML y imágenes JPEG
        con filtros completos por separado, a pesar de que el proxy no tiene 
        información previa sobre lo que enviará al servidor de origen.
        Esto funciona usando un engranaje filtros, que envía a diferentes 
        proveedores dependiendo del contenido en tiempo de ejecución.
        Cualquier filtro puede ser, ya sea insertado directamente en la
        cadena y ejecutado incondicionalmente, o usado como proveedor y
        añadido dinámicamente
        Por ejemplo:
    
        
      
        
    • Un filtro de procesamiento de HTML sólo se ejecuta si el 
          contenido es text/html o application/xhtml + xml.
      • 
        
    • Un filtro de compresión sólo se ejecuta si la entrada es un tipo 
          compresible y no está ya comprimida.
      • 
        
    • Se insertará un filtro de conversión de juego de caracteres,
          si un documento de texto no está ya en el juego de caracteres 
          deseado.
      •

    Filtros expuestos como un servicio HTTP
    

    
    
    Los filtros pueden ser usados para procesar contenido originado 
    desde el cliente además de usarse para procesar el contenido originado
    desde el propio servidor usando el módulo mod_reflector.
    

    
    mod_reflector acepta peticiones POST de los clientes, y
    refleja el cuerpo de la petición POST recibida, dentro del contenido de la 
    respuesta de la petición, pasa a través de la pila del filtro de salida en 
    el camino de vuelta al cliente.
    

    
    Esta técnica se puede utilizar como una alternativa a un servicio web
    que se ejecuta en una pila de de aplicaciones dentro del servidor,
    en donde el filtro de salida proporciona la transformación requerida en el
    cuerpo de la petición. Por ejemplo, el módulo mod_deflate
    puede ser usado para proporcionar un servicio de compresión general,
    o un filtro de transformación de imagen, puede ser convertido en un
    servicio de conversión de imágenes.
    
    

    
    top
    

    

    Usando los Filtros
    
    
    
    Hay dos formas de usar el filtrado: de forma Simple y Dinámica.
    Generalmente, deberá usar una forma u otra; ya que mezclarlas puede
    causar consecuencias inesperadas (a pesar de que reglas de Entrada de 
    tipo simple pueden ser combinadas libremente con reglas de filtrado 
    de Salidas de tipo simple o dinámico).
    
    
    La forma más sencilla es la única manera de configurar filtros de 
    Entrada, y es suficiente para filtros de Salida donde se necesita una
    cadena de filtros estática.
    Las directivas más relevantes son:
        SetInputFilter,
        SetOutputFilter,
        AddInputFilter,
        AddOutputFilter,
        RemoveInputFilter, and
        RemoveOutputFilter.
    

    
    La forma Dinámica habilita ambas configuraciones estática, y dinámica, para los filtros de Salida, como se plantea en la página mod_filter.
    Las directivas más relevantes son:
        FilterChain,
        FilterDeclare, and
        FilterProvider.
    

    
    Una directiva más como es AddOutputFilterByType sigue siendo 
    soportada pero esta obsoleta. Usa en cambio la configuración dinámica.

    This document describes some of the major changes between the
     1.3 and 2.0 versions of the Apache HTTP Server.
    

    


    top
    

    

    Core Enhancements
    
    

    
    
      
    Unix Threading
    

      
    On Unix systems with POSIX threads support, Apache httpd can
      now run in a hybrid multiprocess, multithreaded mode. This
      improves scalability for many, but not all configurations.
    

      
    New Build System
    

      
    The build system has been rewritten from scratch to be
      based on autoconf and libtool.
      This makes Apache httpd's configuration system more similar to
      that of other packages.
    

      
    Multiprotocol Support
    

      
    Apache HTTP Server now has some of the infrastructure in place to
      support serving multiple protocols. mod_echo has
      been written as an example.
    

      
    Better support for non-Unix
      platforms
    

      
    Apache HTTP Server 2.0 is faster and more stable on non-Unix
      platforms such as BeOS, OS/2, and Windows. With the
      introduction of platform-specific multi-processing modules (MPMs) and the
      Apache Portable Runtime (APR), these platforms are now
      implemented in their native API, avoiding the often buggy and
      poorly performing POSIX-emulation layers.
    

      
    New Apache httpd API
    

      
    The API for modules has changed significantly for 2.0.
      Many of the module-ordering/-priority problems from 1.3 should
      be gone. 2.0 does much of this automatically, and module ordering
      is now done per-hook to allow more flexibility. Also, new calls
      have been added that provide additional module capabilities
      without patching the core Apache HTTP Server.
    

      
    IPv6 Support
    

      
    On systems where IPv6 is supported by the underlying
      Apache Portable Runtime library, Apache httpd gets IPv6 listening
      sockets by default. Additionally, the Listen, NameVirtualHost, and VirtualHost directives support
      IPv6 numeric address strings (e.g., "Listen
      [2001:db8::1]:8080").
    

      
    Filtering
    

      
    Apache httpd modules may now be written as filters which act on
      the stream of content as it is delivered to or from the
      server. This allows, for example, the output of CGI scripts to
      be parsed for Server Side Include directives using the
      INCLUDES filter in mod_include. The
      module mod_ext_filter allows external programs to
      act as filters in much the same way that CGI programs can act as
      handlers.
    

      
    Multilanguage Error Responses
    

      
    Error response messages to the browser are now provided in
      several languages, using SSI documents. They may be customized
      by the administrator to achieve a consistent look and feel.
    

      
    Simplified configuration
    

      
    Many confusing directives have been simplified. The often
      confusing Port and BindAddress directives
      are gone; only the Listen
      directive is used for IP address binding; the ServerName directive specifies the
      server name and port number only for redirection and vhost
      recognition.
    

      
    Native Windows NT Unicode Support
    

      
    Apache httpd 2.0 on Windows NT now uses utf-8 for all filename
      encodings. These directly translate to the underlying Unicode
      file system, providing multilanguage support for all Windows
      NT-based installations, including Windows 2000 and Windows XP.
      This support does not extend to Windows 95, 98 or ME, which
      continue to use the machine's local codepage for filesystem
      access.
    

      
    Regular Expression Library Updated
    

      
    Apache httpd 2.0 includes the Perl
      Compatible Regular Expression Library (PCRE).  All regular
      expression evaluation now uses the more powerful Perl 5
      syntax.
    

    
    
  
    top
    

    

    Module Enhancements
    
    

    
    
      
    mod_ssl
    

      
    New module in Apache httpd 2.0. This module is an interface
      to the SSL/TLS encryption protocols provided by
      OpenSSL.
    

      
    mod_dav
    

      
    New module in Apache httpd 2.0. This module implements the HTTP
      Distributed Authoring and Versioning (DAV) specification for
      posting and maintaining web content.
    

      
    mod_deflate
    

      
    New module in Apache httpd 2.0.  This module allows supporting
      browsers to request that content be compressed before delivery,
      saving network bandwidth.
    

      
    mod_auth_ldap
    

      
    New module in Apache httpd 2.0.41.  This module allows an LDAP
      database to be used to store credentials for HTTP Basic
      Authentication.  A companion module, mod_ldap
      provides connection pooling and results caching.
    

      
    mod_auth_digest
    

      
    Includes additional support for session caching across
      processes using shared memory.
    

      
    mod_charset_lite
    

      
    New module in Apache httpd 2.0. This experimental module allows
      for character set translation or recoding.
    

      
    mod_file_cache
    

      
    New module in Apache httpd 2.0. This module includes the
      functionality of mod_mmap_static in Apache HTTP
      Server version 1.3, plus adds further caching abilities.
    

      
    mod_headers
    

      
    This module is much more flexible in Apache httpd 2.0. It can now
      modify request headers used by mod_proxy, and
      it can conditionally set response headers.
    

      
    mod_proxy
    

      
    The proxy module has been completely rewritten to take
      advantage of the new filter infrastructure and to implement a
      more reliable, HTTP/1.1 compliant proxy. In addition, new
      <Proxy>
      configuration sections provide more readable (and internally
      faster) control of proxied sites; overloaded <Directory
      "proxy:..."> configuration are not supported. The module
      is now divided into specific protocol support modules including
      proxy_connect, proxy_ftp and
      proxy_http.
    

      
    mod_negotiation
    

      
    A new ForceLanguagePriority directive can be used to assure that
      the client receives a single document in all cases, rather than
      NOT ACCEPTABLE or MULTIPLE CHOICES responses. In addition, the
      negotiation and MultiViews algorithms have been cleaned up to
      provide more consistent results and a new form of type map that
      can include document content is provided.
    

      
    mod_autoindex
    

      
    Autoindex'ed directory listings can now be configured to
      use HTML tables for cleaner formatting, and allow finer-grained
      control of sorting, including version-sorting, and wildcard
      filtering of the directory listing.
    

      
    mod_include
    

      
    New directives allow the default start and end tags for SSI elements
      to be changed and allow for error and time format configuration
      to take place in the main configuration file rather than in the
      SSI document. Results from regular expression parsing and grouping
      (now based on Perl's regular expression syntax) can be retrieved
      using mod_include's variables $0
      .. $9.
    

      
    mod_auth_dbm
    

      
    Now supports multiple types of DBM-like databases using the
      AuthDBMType directive.

    Shared Object Cache in Apache HTTP Server
    

    

    Available Languages:  en  |
 fr 
    

    

    
    The Shared Object Cache provides a means to share simple data
    across all a server's workers, regardless of thread
    and process models.  It is used where the advantages of sharing
    data across processes outweigh the performance overhead of
    inter-process communication.
    
  
    

    top
    

    

    Shared Object Cache Providers
    
    
    
    The shared object cache as such is an abstraction.  Five different
    modules implement it.  To use the cache, one or more of these modules
    must be present, and configured.
    
    
    The only configuration required is to select which cache provider
    to use.  This is the responsibility of modules using the cache, and
    they enable selection using directives such as
    CacheSocache,
    AuthnCacheSOCache,
    SSLSessionCache, and
    SSLStaplingCache.
    
    
    Currently available providers are:
    
    
    
    
    "dbm" (mod_socache_dbm)
    
    
    This makes use of a DBM hash file.
     The choice of underlying DBM used may be configurable
     if the installed APR version supports multiple DBM implementations.
    
    
    "dc" (mod_socache_dc)
    
    
    This makes use of the distcache
    distributed session caching libraries.
    
    
    "memcache" (mod_socache_memcache)
    
    
    This makes use of the memcached
    high-performance, distributed memory object caching system.
    
    
    "redis" (mod_socache_redis)
    
    
    This makes use of the Redis
    high-performance, distributed memory object caching system.
    
    
    "shmcb" (mod_socache_shmcb)
    
    
    This makes use of a high-performance cyclic buffer inside a
     shared memory segment.
    
    
    

    
    The API provides the following functions:
    

    
    
      
    const char *create(ap_socache_instance_t **instance, const char *arg,
                          apr_pool_t *tmp, apr_pool_t *p);
    
      
    Create a session cache based on the given configuration string.
      The instance pointer returned in the instance parameter will be
      passed as the first argument to subsequent invocations.
    

      
    apr_status_t init(ap_socache_instance_t *instance, const char *cname,
                         const struct ap_socache_hints *hints,
                         server_rec *s, apr_pool_t *pool)
    
      
    Initialize the cache.  The cname must be of maximum length 16
      characters, and uniquely identifies the consumer of the cache
      within the server; using the module name is recommended, e.g.
      "mod_ssl-sess".  This string may be used within a filesystem
      path so use of only alphanumeric [a-z0-9_-] characters is
      recommended.  If hints is non-NULL, it gives a set of hints for
      the provider.  Return APR error code.
    

      
    void destroy(ap_socache_instance_t *instance, server_rec *s)
    
      
    Destroy a given cache instance object.
    

      
    apr_status_t store(ap_socache_instance_t *instance, server_rec *s,
                          const unsigned char *id, unsigned int idlen,
                          apr_time_t expiry,
                          unsigned char *data, unsigned int datalen,
                          apr_pool_t *pool)
    
      
    Store an object in a cache instance.
    

      
    apr_status_t retrieve(ap_socache_instance_t *instance, server_rec *s,
                             const unsigned char *id, unsigned int idlen,
                             unsigned char *data, unsigned int *datalen,
                             apr_pool_t *pool)
    
      
    Retrieve a cached object.
    

      
    apr_status_t remove(ap_socache_instance_t *instance, server_rec *s,
                           const unsigned char *id, unsigned int idlen,
                           apr_pool_t *pool)
    
      
    Remove an object from the cache.
    

      
    void status(ap_socache_instance_t *instance, request_rec *r, int flags)
    
      
    Dump the status of a cache instance for mod_status.
    

      
    apr_status_t iterate(ap_socache_instance_t *instance, server_rec *s,
                            void *userctx, ap_socache_iterator_t *iterator,
                            apr_pool_t *pool)
    
      
    Dump all cached objects through an iterator callback.

      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,

      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You

          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided

      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing

      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

    Ce document couvre l'arrêt et le redémarrage du
    serveur HTTP Apache sur
    les systèmes Unix et similaires. Les utilisateurs de Windows NT, 2000
    and XP doivent consulter
    Exécuter httpd en tant que
    service et les utilisateurs de Windows 9x et ME doivent consulter
    Exécuter httpd comme une
    application de type console pour plus d'informations sur le contrôle
    de httpd à partir de ces plateformes.
    

    


    top
    

    

    Introduction
    

    
    Afin d'arrêter ou redémarrer le serveur HTTP Apache, vous devez envoyer un signal aux
    processus httpd en cours d'exécution.  Les signaux
    peuvent être envoyés de deux manières. La
    première méthode consiste à
    utiliser la commande unix kill
    pour envoyer directement des signaux aux processus. Vous pouvez remarquer
    que plusieurs processus httpd s'exécutent sur votre
    système, mais il vous suffit d'envoyer les signaux au processus parent,
    dont le PID est enregistré dans le fichier précisé par la directive
    PidFile. Autrement dit, vous
    n'aurez jamais besoin d'envoyer des signaux à aucun des
    processus enfants, mais seulement au processus parent. Quatre types
    de signaux peuvent être envoyés au processus parent :
    TERM,
    USR1,
    HUP, et
    WINCH, qui
    seront décrit plus loin.
    

    
    Pour envoyer un signal au processus parent, vous devez entrer une commande
    du style :
    


    kill -TERM `cat /usr/local/apache2/logs/httpd.pid`
    

    
    La seconde méthode permettant d'envoyer des signaux aux processus
    httpd
    consiste à utiliser les options stop,
    restart, graceful et
    graceful-stop du commutateur -k de la ligne
    de commande comme décrit ci-dessous.  Ce sont des arguments du binaire
    httpd, mais il est recommandé de les utiliser
    avec le script de contrôle apachectl, qui se
    chargera de les passer à httpd.
    

    
    Après avoir envoyé un signal à httpd, vous pouvez
    suivre le cours de son action en entrant :
    


    tail -f /usr/local/apache2/logs/error_log
    

    
    Adaptez ces exemples en fonction de la définition de vos directives
    ServerRoot et
    PidFile.
    

    top
    

    

    Arrêter immédiatement
    


    Signal: TERM
    

    apachectl -k stop
    

    

    
    A la réception du signal TERM ou stop,
    le processus parent tente immédiatement
    de tuer tous ses processus enfants. Cela peut durer plusieurs secondes.
    Après cela, le processus parent lui-même se termine. Toutes les requêtes
    en cours sont terminées, et plus aucune autre n'est traitée.
    

    top
    

    

    Redémarrage en douceur
    


    Signal: USR1
    

    apachectl -k graceful
    

    

    
    A la réception du signal USR1 ou
    graceful, le
    processus parent envoie aux processus enfants
    l'ordre de se terminer une fois leur requête courante
    traitée (ou de se terminer immédiatement s'ils n'ont plus rien à traiter).
    Le processus parent relit ses fichiers de configuration et
    réouvre ses fichiers de log. Chaque fois qu'un enfant s'éteint, le
    processus parent le remplace par un processus
    enfant de la nouvelle génération de la
    configuration, et celui-ci commence immédiatement à traiter les
    nouvelles requêtes.
    

    
    Ce code est conçu pour toujours respecter la directive de contrôle
    de processus des modules MPMs, afin que les nombres de processus et de
    threads
    disponibles pour traiter les demandes des clients soient maintenus à
    des valeurs appropriées tout au long du processus de démarrage.
    En outre, il respecte la directive
    StartServers de la manière
    suivante : si après une seconde au moins StartServers nouveaux processus
    enfants n'ont pas été créés, un nombre suffisant de processus
    supplémentaires est créé pour combler le manque. Ainsi le code
    tente de maintenir à la fois le nombre approprié de processus enfants
    en fonction de la charge du serveur, et le nombre de processus défini par la
    directive StartServers.
    

    
    Les utilisateurs du module mod_status
    noteront que les statistiques du serveur ne sont pas
    remises à zéro quand un signal USR1 est envoyé. Le code
    a été conçu à la fois pour minimiser la durée durant laquelle le
    serveur ne peut pas traiter de nouvelles requêtes (elle sont mises en
    file d'attente par le système d'exploitation, et ne sont ainsi jamais
    perdues) et pour respecter vos paramètres de personnalisation.
    Pour y parvenir, il doit conserver le
    tableau utilisé pour garder la trace de tous les processus
    enfants au cours des différentes générations.
    

    
    Dans son état des processus,
    le module status utilise aussi un caractère G afin d'indiquer
    quels processus enfants ont encore des traitements de requêtes en cours
    débutés avant que l'ordre graceful restart ne soit donné.
    

    
    Pour l'instant, il est impossible pour un script de rotation
    des logs utilisant
    USR1 de savoir de manière certaine si tous les processus
    enfants inscrivant des traces de pré-redémarrage sont terminés.
    Nous vous suggérons d'attendre un délai suffisant après l'envoi du
    signal USR1
    avant de faire quoi que ce soit avec les anciens logs. Par exemple,
    si la plupart de vos traitements durent moins de 10 minutes pour des
    utilisateurs empruntant des liaisons à faible bande passante, alors vous
    devriez attendre 15 minutes avant de faire quoi que ce soit
    avec les anciens logs.
    

    
    
    
    Lorsque vous initiez un redémarrage, une vérification de
    la syntaxe est tout d'abord effectuée, afin de s'assurer qu'il n'y a
    pas d'erreurs dans les fichiers de configuration. Si votre fichier de
    configuration comporte des erreurs de syntaxe, vous recevrez un message
    d'erreur les concernant, et le serveur refusera de redémarrer. Ceci
    permet d'éviter la situation où un serveur a
    été arrêté et ne peut plus redémarrer,
    et où vous vous retrouvez avec un serveur hors-service.
    

    
    Ceci ne garantit pas encore que le serveur va redémarrer
    correctement. Pour vérifier la sémantique des fichiers de configuration
    en plus de leur syntaxe, vous pouvez essayer de démarrer
    httpd sous un utilisateur non root.
    S'il n'y a pas d'erreur, il tentera d'ouvrir ses sockets et ses fichiers
    de log et échouera car il n'a pas les privilèges root (ou parce que
    l'instance actuelle de
    httpd est déjà associée à ces ports). S'il échoue
    pour toute autre raison, il y a probablement une erreur dans le
    fichier de configuration et celle-ci doit être corrigée avant de lancer
    le redémarrage en douceur.
    

    top
    

    

    Redémarrer immédiatement
    


    Signal: HUP
    

    apachectl -k restart
    

    

    
    A la réception du signal HUP ou
    restart, le
    processus parent tue ses processus enfants comme pour le signal
    TERM, mais le processus parent ne se termine pas.
    Il relit ses fichiers de configuration, et réouvre ses fichiers de log.
    Puis il donne naissance à un nouveau jeu de processus enfants
    et continue de traiter les requêtes.
    

    
    Les utilisateurs du module mod_status
    noteront que les statistiques du serveur sont remises à zéro quand un
    signal HUP est envoyé.
    


    Comme dans le cas d'un redémarrage "graceful", une
vérification de la syntaxe est effectuée avant que le
redémarrage ne soit tenté. Si votre fichier de configuration comporte
des erreurs de syntaxe, le redémarrage ne sera pas effectué, et
vous recevrez un message concernant ces erreurs.
    

    top
    

    

    Arrêt en douceur
    


    Signal : WINCH
    

    apachectl -k graceful-stop
    

    

    
    A la réception du signal WINCH ou
    graceful-stop, le
    processus parent ordonne à ses processus enfants
    de s'arrêter après le traitement de leur requête en cours
    (ou de s'arrêter immédiatement s'ils n'ont plus de requête à traiter).
    Le processus parent va alors supprimer son fichier
    PidFile et cesser l'écoute
    de tous ses ports. Le processus parent va continuer à s'exécuter,
    et va surveiller les processus enfants
    qui ont encore des requêtes à traiter. Lorsque tous les processus enfants
    ont terminé leurs traitements et se sont arrêtés ou lorsque le délai
    spécifié par la directive GracefulShutdownTimeout a été atteint,
    le processus parent s'arrêtera à son tour.  Si ce délai est atteint,
    tout processus enfant encore en cours d'exécution se verra envoyer
    le signal TERM
    afin de le forcer à s'arrêter.
    

    
    L'envoi du signal TERM va arrêter immédiatement
    les processus parent et enfants en état "graceful". Cependant,
    comme le fichier PidFile
    aura été supprimé, vous ne pourrez pas utiliser
    apachectl ou httpd pour envoyer ce signal.
    

    
    Le signal graceful-stop vous permet d'exécuter
    simultanément plusieurs instances de httpd
    avec des configurations identiques. Ceci s'avère une fonctionnalité
    puissante quand vous effectuez des mises à jour "en douceur"
    de httpd ; cependant, cela peut aussi causer des blocages fatals et des
    situations de compétition (race conditions)
    avec certaines configurations.
    

    
    On a pris soin de s'assurer que les fichiers sur disque
    comme les fichiers verrou (Mutex) et les fichiers socket Unix
    (ScriptSock) contiennent le PID
    du serveur, et coexistent sans problème. Cependant, si une directive de
    configuration, un module tiers ou une CGI résidente utilise un autre
    verrou ou fichier d'état sur disque, il faut prendre soin de s'assurer
    que chaque instance de httpd qui s'exécute
    n'écrase pas les fichiers des autres instances.
    

    
    Vous devez aussi prendre garde aux autres situations de compétition,
    comme l'enregistrement des logs avec un transfert de ceux-ci
    via un pipe vers le programme rotatelogs. Plusieurs instances
    du programme rotatelogs qui tentent d'effectuer
    une rotation des mêmes fichiers de log en même temps peuvent détruire
    mutuellement leurs propres fichiers de log.

    Apache HTTPD supporte la négociation de
    contenu telle qu'elle est décrite
    dans la spécification HTTP/1.1. Il peut choisir la meilleure représentation
    d'une ressource en fonction des préférences du navigateur pour ce qui
    concerne le type de media, les langages, le jeu de caractères et son
    encodage. Il implémente aussi quelques fonctionnalités pour traiter de
    manière plus intelligente les requêtes en provenance de navigateurs qui
    envoient des informations de négociation incomplètes.
    

    
    La négociation de contenu est assurée par le module
    mod_negotiation qui est compilé par défaut
    dans le serveur.

    À propos de la négociation de contenu
    

    
    Une ressource peut être disponible selon différentes représentations.
    Par exemple, elle peut être disponible en différents langages ou pour
    différents types de média, ou une combinaison des deux.
    Pour faire le meilleur choix, on peut fournir à l'utilisateur une page
    d'index, et le laisser choisir. Cependant, le serveur peut souvent faire
    ce choix automatiquement. Ceci est possible car les navigateurs peuvent
    envoyer des informations sur les
    représentations qu'ils préfèrent à l'intérieur de chaque requête.
    Par exemple, un navigateur peut indiquer
    qu'il préfère voir les informations en français, mais qu'en cas
    d'impossibilité l'anglais peut convenir. Les navigateurs indiquent leurs
    préférences à l'aide d'en-têtes dans la requête. Pour ne demander que des
    représentations en français, le navigateur peut utiliser l'en-tête :
    


    Accept-Language: fr
    

    
    Notez qu'il ne sera tenu compte de cette préférence que s'il existe un
    choix de représentations et que ces dernières varient en fonction
    du langage.
    

    
    À titre d'exemple d'une requête plus complexe, ce navigateur a été
    configuré pour accepter le français et l'anglais, avec une préférence pour
    le français, et accepter différents types de média, avec une préférence
    pour HTML par rapport à au texte plat ("plain text") ou autres types de fichiers texte, et
    avec une préférence pour GIF ou JPEG par rapport à tout autre type de
    média, mais autorisant tout autre type de média en dernier ressort :
    


    
  Accept-Language: fr; q=1.0, en; q=0.5
    
  Accept: text/html; q=1.0, text/*; q=0.8, image/gif; q=0.6, image/jpeg; q=0.6, image/*; q=0.5, */*; q=0.1

    

    
    httpd supporte la négociation de contenu "server driven" (telle qu'elle
    est définie dans la spécification HTTP/1.1), où c'est le serveur qui
    décide quelle est la meilleure représentation à retourner pour la ressource
    demandée. Il supporte entièrement les en-têtes de requête
    Accept, Accept-Language,
    Accept-Charset et Accept-Encoding.
    httpd supporte aussi la négociation de contenu transparente, qui est un
    protocole de négociation expérimental défini dans les RFC 2295 et 2296.
    Il ne supporte pas la négociation de fonctionnalité (feature negotiation)
    telle qu'elle est définie dans ces RFCs.
    

    
    Une ressource est une entité conceptuelle identifiée
    par une URI (RFC 2396). Un serveur HTTP comme le serveur HTTP Apache
    propose l'accès à des
    représentations de la ressource à l'intérieur de son
    espace de nommage, chaque représentation étant composée d'une séquence
    d'octets avec la définition d'un type de media, d'un jeu de caractères,
    d'un encodage, etc... A un instant donné, chaque ressource peut être
    associée avec zéro, une ou plusieurs représentations. Si plusieurs
    représentations sont disponibles, la ressource est qualifiée de
    négociable et chacune de ses représentations se nomme
    variante. Les différences entre les
    variantes disponibles d'une ressource négociable constituent les
    dimensions de la négociation.

    La négociation avec httpd
    

    
    Afin de négocier une ressource, on doit fournir au serveur des
    informations à propos de chacune des variantes. Il y a deux manières
    d'accomplir ceci :
    

    
      
      
    • Utiliser une liste de correspondances de type ("type-map") (c'est à dire
      un fichier *.var) qui nomme explicitement les fichiers
      contenant les variantes, ou
      • 

      
    • Utiliser une recherche "multivues", où le serveur effectue une
      recherche de correspondance sur un motif de nom de fichier implicite et
      fait son choix parmi les différents résultats.
      • 
    
    

   
    Utilisation d'un fichier de
   correspondances de types (type-map)
    

    
    Une liste de correspondances de types est un document associé au
    gestionnaire type-map (ou, dans un souci de compatibilité
    ascendante avec des configurations de httpd plus anciennes, le
    type MIME
    application/x-type-map). Notez que pour utiliser cette
    fonctionnalité, vous devez, dans le fichier de configuration, définir un
    gestionnaire qui associe un suffixe de fichier à une type-map;
    ce qui se fait simplement en ajoutant
    


    AddHandler type-map .var
    


    
    dans le fichier de configuration du serveur.
    

    
    Les fichiers de correspondances de types doivent posséder le même nom que
    la ressource qu'ils décrivent, avec pour extension
    .var. Dans l'exemple ci-dessous, la ressource a pour
    nom foo, et le fichier de correspondances se nomme donc
    foo.var.
    

    
    Ce fichier doit comporter une entrée pour chaque variante
    disponible; chaque entrée consiste en une ligne contiguë d'en-têtes au
    format HTTP. les entrées sont séparées par des lignes vides. Les lignes
    vides à l'intérieur d'une entrée sont interdites. Par convention, le
    fichier de correspondances de types débute par une entrée concernant l'entité
    considérée dans son ensemble (bien que ce ne soit pas obligatoire, et
    ignoré si présent). Un exemple de fichier de
    correspondance de types est fourni
    ci-dessous.
    

    
    Les URIs de ce fichier sont relatifs à la localisation du fichier
    de correspondances de types. En général, ces fichiers se trouveront dans le
    même répertoire que le fichier de correspondances de types, mais ce
    n'est pas obligatoire. Vous pouvez utiliser des URIs absolus ou
    relatifs pour tout fichier situé sur le même serveur que le fichier
    de correspondances.
    


    
  URI: foo
    

    
  URI: foo.en.html
    
  Content-type: text/html
    
  Content-language: en
    

    
  URI: foo.fr.de.html
    
  Content-type: text/html;charset=iso-8859-2
    
  Content-language: fr, de
    

    

    
    Notez aussi qu'un fichier de correspondances de types prend le pas sur
    les extensions de noms de fichiers, même si les Multivues sont activées.
    Si les variantes sont de qualités différentes, on doit l'indiquer
    à l'aide du paramètre "qs" à la suite du type de média, comme pour cette
    image
    (disponible aux formats JPEG, GIF, ou ASCII-art) : 
    


    
  URI: foo
    

    
  URI: foo.jpeg
    
  Content-type: image/jpeg; qs=0.8
    

    
  URI: foo.gif
    
  Content-type: image/gif; qs=0.5
    

    
  URI: foo.txt
    
  Content-type: text/plain; qs=0.01
    

    

    
    Les valeurs de qs peuvent varier de 0.000 à 1.000. Notez que toute
    variante possédant une valeur de qs de 0.000 ne sera jamais choisie.
    Les variantes qui n'ont pas de paramètre qs défini se voient attribuer
    une valeur de 1.0. Le paramètre qs indique la qualité relative de la
    variante comparée à celle des autres variantes disponibles, sans tenir
    compte des capacités du client. Par exemple, un fichier JPEG possède
    en général une qualité supérieure à celle d'un fichier ASCII s'il
    représente une photographie. Cependant, si la ressource représentée est
    à un ASCII art original, la représentation ASCII sera de meilleure qualité
    que la représentation JPEG. Ainsi une valeur de qs est associée à une
    variante en fonction de la nature de la ressource qu'elle représente.
    

    
    La liste complète des en-têtes reconnus est disponible dans la
    documentation sur les correspondances de types du
    module mod_negotiation.
    



    Multivues (option Multiviews)
    

    
    MultiViews est une option qui s'applique à un répertoire,
    ce qui signifie qu'elle peut être activée à l'aide d'une directive
    Options à l'intérieur d'une section
    <Directory>, <Location> ou <Files> dans
    httpd.conf, ou (si AllowOverride est correctement positionnée) dans
    des fichiers
    .htaccess. Notez que Options All
    n'active pas MultiViews; vous devez activer cette option en
    la nommant explicitement.
    

    
    L'effet de MultiViews est le suivant : si le serveur reçoit
    une requête pour /tel/répertoire/foo, si
    MultiViews est activée pour
    /tel/répertoire, et si
    /tel/répertoire/foo n'existe pas, le serveur parcourt
    le répertoire à la recherche de fichiers nommés foo.*, et simule
    littéralement une correspondance de types (type map) qui liste tous ces
    fichiers, en leur associant les mêmes types de média et encodages de
    contenu qu'ils auraient eu si le client avait demandé l'accès à l'un
    d'entre eux par son nom. Il choisit ensuite ce qui correspond le mieux
    aux besoins du client.
    

    
    MultiViews peut aussi s'appliquer à la recherche du fichier
    nommé par la directive DirectoryIndex, si le serveur tente d'indexer
    un répertoire. Si les fichiers de configuration spécifient
    

    DirectoryIndex index
    

    
    le serveur va choisir entre index.html
    et index.html3 si les deux fichiers sont présents. Si aucun
    n'est présent, mais index.cgi existe,
    le serveur l'exécutera.
    

    
    Si, parcequ'elle n'est pas reconnue par mod_mime,
    l'extension d'un des fichiers du répertoire ne permet pas de
    déterminer son jeu de caractères, son type de contenu, son langage, ou son
    encodage,  alors
    le résultat dépendra de la définition de la directive MultiViewsMatch. Cette directive détermine
    si les gestionnaires (handlers), les filtres, et autres types d'extensions
    peuvent participer à la négociation MultiVues.

    Les méthodes de négociation
    

    
    Une fois obtenue la liste des variantes pour une ressource donnée,
    httpd dispose de deux méthodes pour choisir la meilleure variante à
    retourner, s'il y a lieu, soit à partir d'un fichier de
    correspondances de types, soit en se basant sur les noms de fichiers du
    répertoire. Il n'est pas nécessaire de connaître en détails comment la
    négociation fonctionne réellement pour pouvoir utiliser les fonctionnalités
    de négociation de contenu de httpd. La suite de ce document explique
    cependant les méthodes utilisées pour ceux ou celles qui sont
    intéressés(ées). 
    

    
    Il existe deux méthodes de négociation :
    

    
      
      
    1. La négociation effectuée par le serveur selon l'algorithme
      de httpd est normalement utilisée. l'algorithme de
      httpd est
      expliqué plus en détails ci-dessous. Quand cet algorithme est utilisé,
      httpd peut parfois "bricoler" le facteur de qualité (qs) d'une dimension
      particulière afin d'obtenir un meilleur résultat.
      La manière dont httpd peut modifier les facteurs de qualité est
      expliquée plus en détails ci-dessous.
      2. 

      
    2. La négociation de contenu transparente est utilisée
      quand le navigateur le demande explicitement selon le mécanisme défini
      dans la RFC 2295. Cette méthode de négociation donne au navigateur le
      contrôle total du choix de la meilleure variante; le résultat dépend
      cependant de la spécificité des algorithmes utilisés par le navigateur.
      Au cours du processus de négociation transparente, le navigateur peut
      demander à httpd d'exécuter l'"algorithme de sélection de variante à
      distance" défini dans la RFC 2296.
      3. 
    
    


    Les dimensions de la négociation
    

    
    
      
      
    
        Dimension

        Notes
      
    

      
    
        Type de média

        Le navigateur affiche ses préférences à l'aide du champ d'en-tête
	Accept. Chaque type de média peut se voir associé un facteur de
	qualité. La description de la variante peut aussi avoir un facteur de
	qualité (le paramètre "qs").
      
    

      
    
        Langage

        Le navigateur affiche ses préférences à l'aide du champ d'en-tête
        Accept-Language. Chaque langue peut se voir associé un facteur de
	qualité. Les variantes peuvent être associées avec zéro, un ou
	plusieurs langages.
      
    

      
    
        Encoding

        Le navigateur affiche ses préférences à l'aide du champ d'en-tête
        Accept-Encoding. Chaque encodage peut se voir associé un facteur de
	qualité.
      
    

      
    
        Charset

        Le navigateur affiche ses préférences à l'aide du champ d'en-tête
        Accept-Charset. Chaque jeu de caractère peut se voir associé un facteur de
	qualité. Les variantes peuvent préciser un jeu de caractères comme
	paramètre du type de média.
      
    
    
    



    L'algorithme de négociation de
httpd
    

    
    httpd peut utiliser l'algorithme suivant pour choisir la "meilleure"
    variante (s'il y en a une) à retourner au navigateur. Cet algorithme n'est pas
    configurable. Il fonctionne comme suit :
    

    
      
      
    1. En premier lieu, pour chaque dimension de la négociation, consulter
      le champ d'en-tête Accept* approprié et assigner une qualité à
      chaque variante. Si l'en-tête Accept* pour toute dimension
      implique que la variante n'est pas acceptable, éliminer cette dernière.
      S'il ne reste plus de variante, aller à l'étape 4.
      2. 

      
    2. 
        Choisir la "meilleure" variante par élimination. Chacun des tests
	suivants est effectué dans cet ordre. Toute variante non sélectionnée
	à l'issue d'un test est éliminée. Après chaque test, s'il reste une
	seule variante, choisir cette dernière comme celle qui correspond le
	mieux puis aller à l'étape 3. S'il reste plusieurs variantes, passer
	au test suivant.

        
        
          
      1. Multiplier le facteur de qualité de l'en-tête
	  Accept par le facteur de qualité "qs" pour le type de
	  média de ces variantes, et choisir la variante qui possède la valeur
	  la plus importante.
        2. 

          
      2. Sélectionner les variantes qui possèdent le facteur de qualité
	  de langage le plus haut.
        3. 

          
      3. Sélectionner les variantes dont le langage correspond le mieux,
          en se basant sur l'ordre des langages de l'en-tête
          Accept-Language (s'il existe), ou de la directive
	  LanguagePriority (si elle existe).
        4. 

          
      4. Sélectionner les variantes possédant le paramètre de média
	  "level" le plus élevé (utilisé pour préciser la version des types de
	  média text/html).
        5. 

          
      5. Sélectionner les variantes possédant le paramètre de média
	  "charset" (jeu de caractères) qui correspond le mieux, en se basant
	  sur la ligne d'en-tête Accept-Charset . Le jeu de
	  caractères ISO-8859-1 est acceptable sauf s'il est explicitement
	  exclus. Les variantes avec un type de média text/*
          mais non explicitement associées avec un jeu de caractères
	  particulier sont supposées être en ISO-8859-1.
        6. 

          
      6. Sélectionner les variantes dont le paramètre de média "charset"
	  associé n'est pas ISO-8859-1. S'il n'en existe pas,
	  sélectionner toutes les variantes.
        7. 

          
      7. Sélectionner les variantes avec le meilleur encodage. S'il existe
	  des variantes avec un encodage acceptable pour le client,
	  sélectionner celles-ci. Sinon, s'il existe des variantes encodées et
	  des variantes non encodées, ne sélectionner que les variantes non
	  encodées. Si toutes les variantes sont encodées ou si aucune
	  ne l'est, sélectionner toutes les variantes.
        8. 

          
      8. Sélectionner les variantes dont le contenu a la longueur
	  la plus courte.
        9. 

          
      9. Sélectionner la première des variantes restantes. Il s'agira
	  soit de la première variante listée dans le fichier de
	  correspondances de types, soit, quand les variantes sont lues depuis
	  le répertoire, la première par ordre alphabétique quand elles sont
	  triées selon le code ASCII.
        10. 
        
      
      
      3. 

      
    3. L'algorithme a maintenant sélectionné une variante considérée comme
      la "meilleure", il la retourne donc au client en guise de réponse.
      L'en-tête HTTP Vary de la réponse est renseigné de façon à
      indiquer les dimensions de la négociation (les navigateurs et les caches
      peuvent utiliser cette information lors de la mise en cache de la
      ressource).  Travail terminé.
      4. 

      
    4. Le passage par cette étape signifie qu'aucune variante n'a été
      sélectionnée (parcequ'aucune n'est acceptable pour le navigateur).
      Envoyer une réponse avec un code de statut 406 (qui signifie "Aucune
      représentation acceptable") et un corps comportant un document HTML qui
      affiche les variantes disponibles. Renseigner aussi l'en-tête HTTP
      Vary de façon à indiquer les dimensions de la variante.
      5.

    Ajustement des valeurs de qualité
    

    
    Parfois httpd modifie les valeurs de qualité par rapport à celles qui
    découleraient d'une stricte interprétation de l'algorithme de négociation
    de httpd ci-dessus, ceci pour améliorer les résultats de l'algorithme pour
    les navigateurs qui envoient des informations incomplètes ou inappropriées.
    Certains des navigateurs les plus populaires envoient des informations dans
    l'en-tête Accept qui, sans ce traitement, provoqueraient la
    sélection d'une variante inappropriée dans de nombreux cas. Quand un
    navigateur envoie des informations complètes et correctes ces ajustements
    ne sont pas effectués.
    


    Types de média et caractères génériques
    

    
    L'en-tête de requête Accept: indique les types de média
    souhaités. Il peut aussi contenir des types de média avec caractères
    génériques, comme "image/*" ou "*/*" où * correspond à n'importe quelle
    chaîne de caractères. Ainsi une requête contenant :
    


    Accept: image/*, */*
    

    
    indiquerait que tout type de média est acceptable, avec une préférence
    pour les types commençant par "image/".
    Certains navigateurs ajoutent par défaut des types de média avec caractères
    génériques aux types explicitement nommés qu'ils peuvent gérer.
    Par exemple :
    


    
  Accept: text/html, text/plain, image/gif, image/jpeg, */*

    
    
    Ceci indique que les types explicitement listés sont préférés, mais
    qu'une représentation avec un type différent de ces derniers conviendra
    aussi.  Les valeurs de qualités explicites,
    afin de préciser ce que veut vraiment le navigateur, s'utilisent
    comme suit :
    

    
  Accept: text/html, text/plain, image/gif, image/jpeg, */*; q=0.01

    
    
    Les types explicites n'ont pas de facteur de qualité, la valeur par
    défaut de leur préférence est donc de 1.0 (la plus haute). Le type avec
    caractères génériques */* se voit attribuer une préférence basse de 0.01,
    si bien que les types autres que ceux explicitement listés ne seront retournés
    que s'il n'existe pas de variante correspondant à un type explicitement
    listé.
    

    
    Si l'en-tête Accept: ne contient pas aucun
    facteur de qualité, httpd positionne la valeur de qualité de
    "*/*", si present, à 0.01 pour simuler l'effet désiré. Il positionne aussi
    la valeur de qualité des types avec caractères génériques au format
    "type/*" à 0.02 (ils sont donc préférés à ceux correspondant à "*/*"). Si
    un type de média dans l'en-tête Accept: contient un facteur de
    qualité, ces valeurs spéciales ne seront pas appliquées, de façon
    à ce que les requêtes de navigateurs qui envoient les informations
    explicites à prendre en compte fonctionnent comme souhaité.
    



    Exceptions dans la négociation du
langage
    

    
    A partir de la version 2.0 de httpd, certaines exceptions ont été
    ajoutées à l'algorithme de négociation afin de ménager une issue de secours
    quand la négociation ne trouve aucun langage correspondant.
    

    
    Quand un client demande une page sur votre serveur, si ce dernier ne
    parvient pas à trouver une page dont la langue corresponde à l'en-tête
    Accept-language envoyé par le navigateur, il enverra au client
    une réponse "Aucune variante acceptable" ou "Plusieurs choix possibles".
    Pour éviter ces
    messages d'erreur, il est possible de configurer httpd de façon à ce que,
    dans ces cas, il ignore l'en-tête Accept-language et fournisse
    tout de même un document, même s'il ne correspond pas exactement à la
    demande explicite du client. La directive ForceLanguagePriority
    peut être utilisée pour éviter ces messages d'erreur et leur substituer une
    page dont le langage sera déterminé en fonction du contenu de la directive
    LanguagePriority.
    

    
    Le serveur va aussi essayer d'étendre sa recherche de correspondance aux
    sous-ensembles de langages quand aucune correspondance exacte ne peut être
    trouvée. Par exemple, si un client demande des documents possédant le
    langage en-GB, c'est à dire anglais britannique, le standard
    HTTP/1.1 n'autorise normalement pas le serveur à faire correspondre cette
    demande à un document dont le langage est simplement en.
    (Notez qu'inclure en-GB et non en dans l'en-tête
    Accept-Language constitue une quasi-erreur de configuration,
    car il est très peu probable qu'un lecteur qui comprend l'anglais
    britannique, ne comprenne pas l'anglais en général. Malheureusement, de
    nombreux clients ont réellement des configurations par défaut de ce type.)
    Cependant, si aucune autre correspondance de langage n'est possible, et que le
    serveur est sur le point de retourner une erreur "Aucune variable
    acceptable" ou de choisir le langage défini par la directive LanguagePriority, le serveur ignorera
    la spécification du sous-ensemble de langage et associera la demande en
    en-GB à des documents en en.  Implicitement,
    httpd ajoute le langage parent à la liste de langues acceptés par le
    client avec une valeur de qualité très basse. Notez cependant que si le
    client demande "en-GB; q=0.9, fr; q=0.8", et le serveur dispose de
    documents estampillés "en" et "fr", alors c'est le document "fr" qui sera
    retourné, tout ceci dans un souci de compatibilité avec la spécification
    HTTP/1.1 et afin de fonctionner efficacement avec les clients
    correctement configurés.
    

    
    Pour supporter les techniques avancées (comme les cookies ou les chemins
    d'URL spéciaux) afin de déterminer le langage préféré de l'utilisateur, le
    module mod_negotiation reconnaît la
    variable d'environnement
    prefer-language
    depuis la version 2.0.47 de httpd. Si elle est définie et contient un
    symbole de langage approprié, mod_negotiation va essayer
    de sélectionner une variante correspondante. S'il n'existe pas de telle
    variante, le processus normal de négociation sera lancé.
    

    
    Exemple
    SetEnvIf Cookie "language=(.+)" prefer-language=$1
Header append Vary cookie

    Extensions à la négociation de contenu
transparente
    


    httpd étend le protocole de négociation de contenu transparente (RFC
2295) comme suit. Un nouvel élément {encodage ..} est utilisé dans
les listes de variantes pour marquer celles qui ne sont disponibles qu'avec un
encodage de contenu spécifique. L'implémentation de l'algorithme
RVSA/1.0 (RFC 2296) est étendue à la reconnaissance de variantes encodées dans
la liste, et à leur utilisation en tant que variantes candidates à partir du
moment où leur encodage satisfait au contenu de l'en-tête de requête
Accept-Encoding. L'implémentation RVSA/1.0 n'arrondit pas les
facteurs de qualité calculés à 5 décimales avant d'avoir choisi la meilleure
variante.

    Remarques à propos des liens hypertextes et des
conventions de nommage
    

    
    Si vous utilisez la négociation de langage, vous avez le choix entre
    différentes conventions de nommage, car les fichiers peuvent posséder
    plusieurs extensions, et l'ordre dans lequel ces dernières apparaissent
    est en général sans rapport (voir la documentation sur le module mod_mime
    pour plus de détails).
    

    
    Un fichier type possède une extension liée au type MIME
    (par exemple, html), mais parfois aussi une
    extension liée à l'encodage (par exemple, gz),
    et bien sûr une extension liée au langage
    (par exemple, en) quand plusieurs variantes de
    langage sont disponibles pour ce fichier.
    

    
    Exemples :

    En regardant la table ci-dessus, vous remarquerez qu'il est toujours
    possible d'utiliser le nom de fichier sans extension dans un lien
    (par exemple, foo). L'avantage est de pouvoir
    dissimuler le type réel du fichier associé à un document et de pouvoir
    le modifier
    ultérieurement, par exemple, de html à
    shtml ou cgi sans avoir à
    mettre à jour aucun lien.
    

    
    Si vous souhaitez continuer à utiliser un type MIME dans vos liens
    (par exemple  foo.html), l'extension liée au langage
    (y compris une extension liée à l'encodage s'il en existe une)
    doit se trouver à droite de l'extension liée au type MIME
    (par exemple, foo.html.en).

    Remarque sur la mise en cache
    

    
    Quand un cache stocke une représentation, il l'associe avec l'URL de la
    requête. Lorsque cette URL est à nouveau demandée, le cache peut utiliser
    la représentation stockée. Cependant, si la ressource est négociable au
    niveau du serveur, il se peut que seule la première variante demandée soit
    mise en cache et de ce fait, la correspondance positive du cache peut
    entraîner une réponse inappropriée. Pour
    éviter ceci, httpd marque par
    défaut toutes les réponses qui sont retournées après une négociation de
    contenu comme "non-cachables" par les clients HTTP/1.0. httpd supporte
    aussi les fonctionnalités du protocole HTTP/1.1 afin de permettre la mise
    en cache des réponses négociées.
    

    
    Pour les requêtes en provenance d'un client compatible HTTP/1.0
    (un navigateur ou un cache), la directive CacheNegotiatedDocs peut être utilisée
    pour permettre la mise en cache des réponses qui ont fait l'objet d'une
    négociation. Cette directive peut intervenir dans la configuration au
    niveau du serveur ou de l'hôte virtuel, et n'accepte aucun argument. Elle
    n'a aucun effet sur les requêtes en provenance de clients HTTP/1.1.
    

    
    Pour les clients HTTP/1.1, httpd envoie un en-tête de réponse HTTP
    Vary afin d'indiquer les dimensions de la négociation pour
    cette réponse. Les caches peuvent
    utiliser cette information afin de déterminer
    si une requête peut être servie à partir de la copie locale. Pour inciter
    un cache à utiliser la copie locale sans tenir compte des dimensions de la
    négociation, définissez la
    variable d'environnement
    force-no-vary.

    suEXEC
    機能により、Apache ユーザは Web サーバを実行しているユーザ ID とは
    異なるユーザ ID で CGI プログラムや SSI 
    プログラムを実行することができます。CGI プログラムまたは SSI
    プログラムを実行する場合、通常は web サーバと同じユーザで実行されます。
    
    

    
    適切に使用すると、この機能によりユーザが個別の CGI
    や SSI プログラムを開発し実行することで生じるセキュリティ上の危険を、
    かなり減らすことができます。しかし、suEXEC の設定が不適切だと、
    多くの問題が生じ、あなたのコンピュータに新しいセキュリティホールを
    作ってしまう可能性があります。あなたが setuid root
    されたプログラムと、それらから生じるセキュリティ上の問題の管理に
    詳しくないようなら、suEXEC の使用を検討しないように強く推奨します。

    始める前に
    

    
    この文書の先頭に飛ぶ前に、Apache
    グループとこの文書での仮定を知っておくべきでしょう。
    
    

    
    第 1 に、あなたが setuid と
    setgid 操作が可能な UNIX
    由来のオペレーティングシステムを使っていることを想定しています。
    これは、すべてのコマンド例にあてはまります。
    その他のプラットホームでは、もし suEXEC
    がサポートされていたとしても設定は異なるかもしれません。
    

    
    第 2 に、あなたが使用中のコンピュータの
    セキュリティに関する基本的な概念と、それらの管理について詳しいことを
    想定しています。これは、setuid/setgid
    操作、あなたのシステム上でのその操作による様々な効果、
    セキュリティレベルについてあなたが理解しているということを含みます。
    
    

    
    第 3 に、改造されていない suEXEC
    コードの使用を想定しています。suEXEC のコードは、
    多くのベータテスタだけでなく、開発者によっても注意深く精査され
    テストされています。それらの注意により、簡潔で信頼できる安全な
    コードの基盤が保証されます。このコードを改変することで、
    予期されない問題や新しいセキュリティ上の危険が生じることがあります。
    セキュリティプログラミングの詳細に通じていて、
    今後の検討のために成果を Apache
    グループと共有しようと思うのでなければ、suEXEC
    コードは変えないことを 強く推奨します。
    

    
    第 4 に、これが最後ですが、suEXEC を Apache
    のデフォルトインストールには含めないことが
    Apache グループで決定されています。これは、suEXEC
    の設定には管理者の詳細にわたる慎重な注意が必要だからです。
    suEXEC の様々な設定について検討が終われば、管理者は suEXEC
    を通常のインストール方法でインストールすることができます。
    これらの設定値は、suEXEC
    機能の使用中にシステムセキュリティを適切に保つために、
    管理者によって慎重に決定され指定されることが必要です。
    この詳細な手順により、Apache グループは、suEXEC
    のインストールについて、注意深く十分に検討してそれを使用することを
    決定した場合に限っていただきたいと考えています。
    
    

    
    それでも進みますか? よろしい。では、先へ進みましょう!

    suEXEC セキュリティモデル
    

    
    suEXEC の設定とインストールを始める前に、
    まず実装しようとしているセキュリティモデルについて論じておきます。
    それには、suEXEC の内部で行なわれていること、
    システムのセキュリティを保証するために警告されることを
    よく理解しておいた方がよいでしょう。
    

    
    suEXEC は、Apache web
    サーバから呼び出される setuid された "wrapper"
    プログラムが基本となっています。設計した CGI、または SSI
    プログラムへの HTTP リクエストがあると、この wrapper
    が呼び出されます。このようなリクエストがあると、Apache
    はそのプログラムが実行される際のプログラム名とユーザ ID とグループ
    ID を指定して suEXEC wrapper を実行します。
    
    

    
    それから、wrapper は成功または失敗を決定するため
    以下の処理を行ないます。これらの状態のうち一つでも失敗した場合、
    プログラムは失敗をログに記録してエラーで終了します。
    そうでなければ、後の処理が続けられます。
    

    
      
      
    1. 
        wrapper
        を実行しているユーザはこのシステムの正当なユーザか?

        
      
          これは、wrapper を実行しているユーザが
          本当にシステムの利用者であることを保証するためです。
        
      
      
      2. 


     
    2. 
        wrapper が適切な数の引数で呼び出されたか?


        
      
          wrapper は適切な数の引数が与えられた場合にのみ実行されます。
          適切な引数のフォーマットは Apache Web サーバに解釈されます。
          適切な数の引数を受け取らなければ、攻撃をされたか
          あなたの Apache バイナリの suEXEC の部分が
          どこかおかしい可能性があります。
        
      
      
      3. 

      
    3. 
        この正当なユーザは wrapper
        の実行を許可されているか?

        
      
          このユーザは wrapper 実行を許可されたユーザですか?
          ただ一人のユーザ (Apache ユーザ) だけが、
          このプログラムの実行を許可されます。
        
      
      
      4. 

      
    4. 
        対象の CGI, SSI プログラムが安全でない階層の参照をしているか?
        

        
      
          対象の CGI, SSI プログラムが '/' から始まる、または
          '..' による参照を行なっていますか? これらは許可されません。
          対象のプログラムは suEXEC のドキュメントルート
          (下記の --with-suexec-docroot=DIR を参照)
          内に存在しなければなりません。
        
      
      
      5. 

      
    5. 
        対象となるユーザ名は正当なものか?

        
      
          対象となるユーザ名は存在していますか?
        
      
      
      6. 

      
    6. 
        対象となるグループ名は正当なものか?

        
      
          対象となるグループ名は存在していますか?
        
      
      
      7. 

      
    7. 
        目的のユーザはスーパーユーザではないか?
        

        
      
          今のところ、suEXEC は root による CGI/SSI
          プログラムの実行を許可していません。
        
      
      
      8. 

      
    8. 
        対象となるユーザ ID は、最小の ID
        番号よりも大きいか?  

        
      
          最小ユーザ ID 番号は設定時に指定されます。これは、
          CGI/SSI プログラム実行を許可されるユーザ ID
          のとりうる最小値です。これは
          "system" 用のアカウントを閉め出すのに有効です。
        
      
      
      9. 

      
    9. 
        対象となるグループはスーパーユーザのグループでは
        ないか?

        
      
         今のところ、suEXEC は 'root' グループによる CGI/SSI
         プログラムの実行を許可していません。
        
      
      
      10. 

      
    10. 
        対象となるグループ ID は最小の ID
          番号よりも大きいか?

        
      
          最小グループ ID 番号は設定時に指定されます。これは、
          CGI/SSI プログラム実行を許可されるグループ
          ID のとりうる最小値です。
          これは "system" 用のグループを閉め出すのに有効です。
        
      
      
      11. 

      
    11. 
        wrapper が正常に対象となるユーザとグループになれるか?
        

        
      
          ここで、setuid と setgid
          の起動によりプログラムは対象となるユーザとグループになります。
          グループアクセスリストは、
          ユーザが属しているすべてのグループで初期化されます。
        
      
      
      12. 

      
    12. 
        CGI/SSI プログラムが置かれているディレクトリに移動
        (change directory) できるか?

        
      
          ディレクトリが存在しないなら、そのファイルも存在しないかもしれません。
          ディレクトリに移動できないのであれば、おそらく存在もしないでしょう。
        
      
      
      13. 

      
    13. 
        ディレクトリが Apache のドキュメントツリー内にあるか?
        

        
      
          リクエストがサーバ内のものであれば、
          要求されたディレクトリが suEXEC のドキュメントルート配下にありますか?
          リクエストが UserDir のものであれば、要求されたディレクトリが suEXEC 
          のユーザのドキュメントルート配下にありますか?
          (suEXEC 設定オプション 参照)
        
      
      
      14. 

      
    14. 
        ディレクトリを他のユーザが書き込めるようになって
        いないか?

        
      
          ディレクトリを他ユーザに開放しないようにします。
          所有ユーザだけがこのディレクトリの内容を改変できるようにします。
        
      
      
      15. 


      
    15. 
        対象となる CGI/SSI プログラムは存在するか?

        
      
          存在しなければ実行できません。
        
      
      
      16. 

      
    16. 
        対象となる CGI/SSI プログラムファイルが他アカウントから
        書き込めるようになっていないか?

        
      
          所有者以外には CGI/SSI プログラムを変更する権限は与えられません。
        
      
      
      17. 


      
    17. 
        対象となる CGI/SSI プログラムが setuid または setgid 
        されていないか?

        
      
          UID/GID を再度変更してのプログラム実行はしません
        
      
      
      18. 


      
    18. 
        対象となるユーザ/グループがプログラムの
        ユーザ/グループと同じか?

        
      
          ユーザがそのファイルの所有者ですか?
        
      
      
      19. 

      
    19. 
        安全な動作を保証するための環境変数クリアが可能か?
        

        
      
          suEXEC は、安全な環境変数のリスト
          (これらは設定時に作成されます) 内の変数として渡される安全な
          PATH 変数 (設定時に指定されます) を設定することで、
          プロセスの環境変数をクリアします。
        
      
      
      20. 


      
    20. 
        対象となる CGI/SSI プログラムを exec して実行できるか?


        
      
          ここで suEXEC が終了し、対象となるプログラムが開始されます。
        
      
      
      21. 
    
    

    
    ここまでが suEXEC の wrapper
    におけるセキュリティモデルの標準的な動作です。もう少し厳重に
    CGI/SSI 設計についての新しい制限や規定を取り入れることもできますが、
    suEXEC はセキュリティに注意して慎重に少しずつ開発されてきました。
    
    

    
    このセキュリティモデルを用いて
    サーバ設定時にどのように許すことを制限するか、また、suEXEC
    を適切に設定するとどのようなセキュリティ上の危険を避けられるかに
    関するより詳しい情報については、"とかげに注意"
    (Beware the Jabberwock) の章を参照してください。

    suEXEC
    の設定とインストール
    

    
    ここから楽しくなります。
    

    
    suEXEC
    設定オプション
    
    
    

    
    
      
    --enable-suexec
    

      
    このオプションは、デフォルトではインストールされず、
      有効にはならない suEXEC 機能を有効にします。
      suEXEC を使うように APACI に要求するには、--enable-suexec
      オプションにあわせて少なくとも一つは --with-suexec-xxxxx
      オプションが指定されなければなりません。
    

      
    --with-suexec-bin=PATH
    

      
    セキュリティ上の理由により、suexec バイナリのパスはサーバに
      ハードコードされている必要があります。デフォルトのパスを
      変えたいときはこのオプションを使ってください。例えば、
      --with-suexec-bin=/usr/sbin/suexec のように。
    

      
    --with-suexec-caller=UID
    

      
    Apache を通常動作させるユーザ名を指定します。
      このユーザだけが suexec の実行を許可されたユーザになります。
    

      
    --with-suexec-userdir=DIR
    

      
    suEXEC がアクセスを許されるユーザホームディレクトリ配下の
      サブディレクトリを指定します。
      このディレクトリ以下の全実行ファイルは、"安全な"プログラムになるよう、
      suEXEC がそのユーザとして実行できるようにします。
      "単純な" UserDir ディレクティブを使っている場合 
      (すなわち "*" を含まないもの)、これと同じ値を設定すべきです。
      Userdir ディレクティブがそのユーザのパスワードファイル内の
      ホームディレクトリと同じ場所を指していなければ、
      suEXEC は適切に動作しません。デフォルトは "public_html" です。
      
    
      各 UserDir が異なった仮想ホストを設定している場合、
      それらを全て一つの親ディレクトリに含めて、
      その親ディレクトリの名前をここで指定する必要があります。
      このように指定されなければ "~userdir" cgi
      へのリクエストが動作しません。
    

      
    --with-suexec-docroot=DIR
    

      
    Apache のドキュメントルートを設定します。これが suEXEC
      の動作で使用する唯一のディレクトリ階層になります (UserDir
      の指定は別)。デフォルトでは --datedir に "/htdocs"
      というサフィックスをつけたものです。
      "--datadir=/home/apache" として設定すると、
      suEXEC wrapper にとって "/home/apache/htdocs"
      がドキュメントルートとして使われます。
    

      
    --with-suexec-uidmin=UID
    

      
    suEXEC の対象ユーザとして許される UID の最小値を指定します。
      大抵のシステムでは 500 か 100 が一般的です。
      デフォルト値は 100 です。
    

      
    --with-suexec-gidmin=GID
    

      
    suEXEC の対象グループとして許される GID
      の最小値を指定します。大抵のシステムでは 100 が一般的なので、
      デフォルト値としても 100 が使われています。
    

      
    --with-suexec-logfile=FILE
    

      
    suEXEC の処理とエラーが記録されるファイル名を指定します。
      (監査やデバッグ目的に有用)
      デフォルトではログファイルは "suexec_log" という名前で、
      標準のログファイルディレクトリ (--logfiledir) に置かれます。
      
    

      
    --with-suexec-safepath=PATH
    

      
    CGI 実行ファイルに渡される安全な PATH 環境変数です。
      デフォルト値は "/usr/local/bin:/usr/bin:/bin" です。
      
    
    
    

    
    suEXEC wrapper
    のコンパイルとインストール
    
    --enable-suexec オプションで suEXEC 機能を有効にすると、
    "make" コマンドを実行した時に suexec のバイナリ (Apache 自体も)
    が自動的に作成されます。
    
    
    すべての構成要素が作成されると、それらのインストールには
    make install コマンドが実行できます。バイナリイメージの suexec
    は --sbindir オプションで指定されたディレクトリにインストールされます。
    デフォルトの場所は "/usr/local/apache/bin/suexec" です。
    
    インストール時には root
    権限が必要なので注意してください。wrapper がユーザ ID
    を設定するために、所有者 root
    でのセットユーザ ID
    ビットをそのファイルのモードに設定しなければなりません。
    
    

    
    安全なパーミッションを設定する
    
    suEXEC ラッパーは、--with-suexec-caller configure 
    オプションで指定した正しいユーザで起動されていることを確認しますが、
    システム上でこのチェックが行なわれる前に、
    suEXEC が呼ぶシステムやライブラリが脆弱である可能性は残ります。対抗策として、
    一般に良い習慣ともされいますが、
    ファイルシステムパーミッションを使って
    Apache の実行時のグループのみが suEXEC を実行できるように
    するのが良いでしょう。
    

    
    たとえば、次のようにサーバが設定されていたとします。
    


    
    User www
    
    Group webgroup
    

    

    
    suexec が "/usr/local/apache2/bin/suexec" 
    にインストールされていた場合、次のように設定する必要があります。
    


    
    chgrp webgroup /usr/local/apache2/bin/suexec
    
    chmod 4750 /usr/local/apache2/bin/suexec
    

    

    
    これで Apache が実行されるグループのみが 
    suEXEC ラッパーを実行できるということを
    確証します。
    
  
    top
    

    

    suEXEC
    の有効化と無効化
    

    
    起動時に、Apache は --sbindir
    オプションで設定されたディレクトリで
    suexec を探します
    (デフォルトは "/usr/local/apache/sbin/suexec") 。
    適切に設定された suEXEC がみつかると、
    エラーログに以下のメッセージが出力されます。
    


    
    [notice] suEXEC mechanism enabled (wrapper: /path/to/suexec)

    

    
    サーバ起動時にこのメッセージが出ない場合、
    大抵はサーバが想定した場所で wrapper プログラムが見つからなかったか、
    setuid root としてインストールされていないかです。
    

    
    suEXEC の仕組みを使用するのが初めてで、Apache が既に動作中であれば、
    Apache を kill して、再起動しなければなりません。HUP シグナルや
    USR1 シグナルによる単純な再起動では不十分です。
    
    
    suEXEC を無効にする場合は、suexec ファイルを削除してから
    Apache を kill して再起動します。
    
    
  
    top
    

    

    suEXEC の使用
    

    
    CGI プログラムへのリクエストが suEXEC ラッパーを呼ぶのは、
    SuexecUserGroup ディレクティブを
    含むバーチャルホストへのリクエストか、mod_userdir により
    処理されたリクエストの場合に限ります。
    

    
    仮想ホスト:
    
    suEXEC wrapper の使い方として、
    VirtualHost 設定での
    SuexecUserGroup
    ディレクティブを通したものがあります。
    このディレクティブをメインサーバのユーザ ID
    と異なるものにすると、CGI リソースへのすべてのリクエストは、その
    <VirtualHost> で指定された User と
    Group として実行されます。<VirtualHost>
    でこのディレクティブが指定されていない場合、
    メインサーバのユーザ ID が想定されます。
    

    
    ユーザディレクトリ:
    
    mod_userdir により処理されたリクエストは
    リクエストされたユーザディレクトリのユーザ ID で CGI プログラムを
    実行するために suEXEC ラッパーを呼びます。
    この機能を動作させるために必要なことは、CGI
    をそのユーザで実行できること、そのスクリプトが上記のセキュリティ検査をパスできることです。
    コンパイル
     時のオプション --with-suexec-userdir も参照してください。
    
  
    top
    

    

    suEXEC のデバッグ
    

    
    suEXEC wrapper は、上記で述べた --with-suexec-logfile
    オプションで指定されたファイルにログ情報を記録します。
    wrapper を適切に設定、インストールできていると思う場合、
    どこで迷っているか見ようとするならこのログとサーバの
    エラーログを見るとよいでしょう。

          ユーザディレクトリへのリクエストにおける個々のユーザの最上位の
          ドキュメントルート内に残らなければなりません。

    This document describes the use of filters in Apache.

    Filtering in Apache 2
    
    
    
    Related ModulesRelated Directives
    


    The Filter Chain is available in Apache 2.0 and higher,
and enables applications to process incoming and outgoing data
in a highly flexible and configurable manner, regardless of
where the data comes from.  We can pre-process incoming data,
and post-process outgoing data, at will.  This is basically
independent of the traditional request processing phases.
    

    
Filters can be chained, in a Data Axis orthogonal to request processing

    

    Some examples of filtering in the standard Apache distribution are:
    


    Apache also uses a number of filters internally to perform
functions like chunking and byte-range handling.
    


    A wider range of applications are implemented by third-party filter
modules.  A few of these are:
    


      

    • HTML and XML processing and rewriting
      • 

    • XSLT transforms and XIncludes
      • 

    • XML Namespace support
      • 

    • File Upload handling and decoding of HTML Forms
      • 

    • Image processing
      • 

    • Protection of vulnerable applications such as PHP scripts
      • 

    • Text search-and-replace editing
      • 

    

    top
    

    

    Smart Filtering
    


    
Smart filtering applies different filter providers according to the state of request processing

    

    mod_filter, included in Apache 2.1 and later,
enables the filter chain to be configured dynamically at run time.
So for example you can set up a proxy to rewrite
HTML with an HTML filter and JPEG images with a completely
separate filter, despite the proxy having no prior information
about what the origin server will send.  This works by using a
filter harness, that dispatches to different providers according
to the actual contents at runtime.  Any filter may be either
inserted directly in the chain and run unconditionally, or
used as a provider and inserted dynamically.  For example,
    

      

    • an HTML processing filter will only run if the content is
text/html or application/xhtml+xml
      • 

    • A compression filter will only run if the input is a
compressible type and not already compressed
      • 

    • A charset conversion filter will be inserted if a text
document is not already in the desired charset
      • 

    

    top
    

    

    Exposing Filters as an HTTP Service
    



    Filters can be used to process content originating from the client in
addition to processing content originating on the server using the
mod_reflector module.
    


    mod_reflector accepts POST requests from clients, and reflects
the content request body received within the POST request back in the response,
passing through the output filter stack on the way back to the client.
    


    This technique can be used as an alternative to a web service running within
an application server stack, where an output filter provides the transformation
required on the request body. For example, the mod_deflate
module might be used to provide a general compression service, or an image
transformation filter might be turned into an image transformation service.
    


    top
    

    

    Using Filters
    


    There are two ways to use filtering: Simple and Dynamic.
In general, you should use one or the other; mixing them can
have unexpected consequences (although simple Input filtering
can be mixed freely with either simple or dynamic Output filtering).
    

    The Simple Way is the only way to configure input filters, and is
sufficient for output filters where you need a static filter chain.
Relevant directives are
    SetInputFilter,
    SetOutputFilter,
    AddInputFilter,
    AddOutputFilter,
    RemoveInputFilter, and
    RemoveOutputFilter.
    


    The Dynamic Way enables both static and flexible, dynamic configuration
of output filters, as discussed in the mod_filter page.
Relevant directives are
    FilterChain,
    FilterDeclare, and
    FilterProvider.
    


    One further directive AddOutputFilterByType is still supported,
but deprecated.  Use dynamic configuration instead.

            die neuesten Änderungen.
    

    
    Dieses Dokument umfaßt nur die Kompilierung und Installation des
    Apache auf Unix und Unix-ähnlichen Systemen. Für die
    Kompilierung und Installation unter Windows lesen Sie bitte Den Apache unter Microsoft Windows
    betreiben. Für andere Plattformen lesen Sie bitte die
    Dokumentation Plattformen.
    

    
    Die Konfigurations- und Installationsumgebung des Apache 2.0 hat sich
    seit dem Apache 1.3 komplett verändert. Der Apache 1.3 benutzt einen
    speziellen Satz von Skripten, um eine einfache Installation zu
    ermöglichen. Der Apache 2.0 dagegen verwendet nun
    libtool und autoconf, um eine Umgebung zu
    schaffen, die der vieler anderer Open Source Projekte ähnlich
    sieht.
    

    
    Wenn Sie von einer Unterversion auf die nächste aktualisieren (z.B.
    von 2.0.50 auf 2.0.51), springen Sie bitte zum Abschnitt Upgrade.

        $ lynx http://httpd.apache.org/download.cgi
        
      
    

      
    
        Auspacken

        $ gzip -d httpd-2_1_NN.tar.gz
    
         $ tar xvf httpd-2_1_NN.tar         		
      
    

      
    
        Konfigurieren

        $ ./configure --prefix=PREFIX
        
      
    

      
    
        Kompilieren

        $ make

        $ make install 
      
    

      
    
        Anpassen

        $ vi PREFIX/conf/httpd.conf 
      
    

      
    
        Testen

        $ PREFIX/bin/apachectl start
        
      
    
    
    

    
    NN muss durch die Nummer der Unterversion ersetzt werden,
    und PREFIX durch den Verzeichnispfad,
    in dem der Server installiert werden soll. Wenn PREFIX nicht
    angegeben ist, wird die Voreinstellung /usr/local/apache2
    verwendet.
    

    
    Beginnend mit den Anforderungen
    für die Kompilierung und Installation des Apache HTTPD ist
    weiter unten jeder Abschnitt des Kompilierungs- und
    Installationsvorganges genauer beschrieben.
    

    top
    

    

    Anforderungen
    

    
    Folgende Anforderungen gelten für die Erstellung des
    Apache:
    

    
    
      
    Plattenplatz
    
      
    Stellen Sie sicher, dass Sie kurzzeitig wenigstens 50 MB freien
      Festplattenplatz zur Verfügung haben. Nach der Installation
      belegt der Apache ungefähr 10 MB Plattenplatz. Der
      tatsächliche Platzbedarf variiert in Abhängigkeit von den
      gewählten Konfigurationseinstellungen und
      Modulen von Drittanbietern.
    

      
    ANSI-C-Compiler und Generierungswerkzeuge
    
      
    Stellen Sie sicher, dass Sie einen ANSI-C Compiler installiert
      haben. Der GNU C
      Compiler (GCC) der Free Software
      Foundation (FSF) ist empfehlenswert (Version 2.7.2 ist gut). Wenn
      Sie den GCC nicht besitzen, stellen Sie zumindest sicher, dass der
      Compiler Ihres Anbieters ANSI-kompatibel ist. Außerdem muss Ihr
      PATH wesentliche Generierungswerkzeuge wie
      make enthalten.
    

      
    Zeitgenauigkeit bewahren
    
      
    Elemente des HTTP-Protokolls werden in Form einer Tageszeit
      ausgedrückt. Darum sollten Sie jetzt prüfen, ob Ihr System
      die Fähigkeit zur Zeitsynchronisation besitzt, und diese
      gegebenenfalls installieren. Üblicherweise werden hierfür
      die Programme ntpdate oder xntpd verwendet,
      die auf dem Network Time Protocol (NTP) basieren. Nähere
      Informationen über NTP Software und öffentliche Zeitserver
      finden Sie in der Usenet Newsgroup comp.protocols.time.ntp
      und auf der NTP
      Homepage.
    

      
    Perl 5
      [OPTIONAL]
    
      
    Für einige Hilfsskripte wie apxs
      oder dbmmanage (die in Perl
      geschrieben sind) wird der Perl 5 Interpreter benötigt (die
      Versionen ab 5.003 sind ausreichend). Wenn Sie mehrere Perl
      Interpreter haben (beispielsweise eine systemweite Installation von
      Perl 4 und Ihre eigene Perl 5-Installation), dann sollten Sie die
      --with-perl-Option (siehe unten) verwenden, um
      sicherzustellen, dass der richtige Interpreter von
      configure ausgewählt wird.
      Wenn kein Perl 5-Interpreter vom configure-Skript
      gefunden werden kann, können Sie die betroffenen Hilfsskripte nicht
      verwenden, sind jedoch selbstverständlich nach wie vor in der Lage,
      den Apache 2.0 zu bauen und zu installieren.
    
    
    

    top
    

    

    Download
    

    
    Der Apache kann von der Apache HTTP Server
    Downloadseite heruntergeladen werden, auf der verschiedene Spiegelserver
    angegeben sind. Für die meisten Benutzer des Apache ist es auf
    Unix-ähnlichen Systemen am Besten, die Quellcodeversion herunterzuladen
    und zu kompilieren. Der Erstellungsprozess (weiter unten beschrieben) ist
    einfach und erlaubt es Ihnen, den Server Ihren Bedürfnissen anzupassen.
    Dazu kommt, dass Binärdistributionen gegenüber der aktuellen
    Quellcodeversion oft veraltet sind. Wenn Sie tatsächlich ein
    Binärpaket herunterladen, folgen Sie bitte den Anweisungen in der Datei
    INSTALL.bindist, die der Distribution beiliegt.
    

    
    Es ist wichtig, dass Sie nach dem Herunterladen überprüfen,
    dass es sich um einer vollständige und unveränderte Version des
    Apache HTTP Servers handelt. Das können Sie erreichen, indem Sie das
    heruntergeladene Paket gegen die PGP-Signatur prüfen. Einzelheiten dazu
    erfahren Sie auf der Download-Seite. Es
    ist auch ein erweitertes Beispiel verfügbar, dass die Anwendung von PGP
    beschreibt.
    


    top
    

    

    Auspacken
    

    
    Das Auspacken des Quellcodes aus dem Apache HTTPD Tarball besteht
    aus einem simplen Dekomprimieren und danach "Ent-tarren":
    

  
    
      $ gzip -d httpd-2_1_NN.tar.gz
    
      $ tar xvf httpd-2_1_NN.tar
  
    

    
    Dies erstellt unterhalb des aktuellen Verzeichnisses ein neues
    Verzeichnis, das den Quellcode für die Distribution enthält.
    Sie sollten mit cd in dieses Verzeichnis wechseln,
    bevor Sie mit der Kompilierung des Servers weitermachen. 
    


    top
    

    

    Den Codebaum konfigurieren
    

    
    Der nächste Schritt ist die Konfiguration des
    Apache-Codebaumes für Ihre spezielle Plattform und Ihre
    persönlichen Bedürfnisse. Dies wird mit dem Skript
    configure durchgeführt, das im Wurzelverzeichnis
    der Distribution enthalten ist. (Entwickler, welche die CVS Version
    des Apache-Codebaumes herunterladen, müssen autoconf
    und libtool installiert haben und müssen
    buildconf ausführen, bevor sie mit den
    nächsten Schritten fortfahren können. Dies wird bei
    offiziellen Releases nicht notwendig sein.)
    

    
    Um den Codebaum mit den Standardeinstellungen zu konfigurieren,
    geben Sie einfach ./configure ein. Zur Änderung
    dieser Voreinstellungen akzeptiert configure eine
    Reihe von Variablen und Kommandozeilenoptionen.
    

    
    Die wichtigste Option ist --prefix, der Ablageort, an dem
    der Apache später installiert wird, da er für diesen Ort
    konfiguriert werden muss, um korrekt zu arbeiten. Eine feinere Einstellung
    der Dateiablagen ist mit weiteren configure-Optionen
    möglich.
    

    
    Weiterhin können Sie zu diesem Zeitpunkt festlegen, welche Funktionalität Sie
    in den Apache aufnehmen möchten, indem Sie Module
    aktivieren oder deaktivieren. Der Apache bindet standardmäßig
    einen Satz von Basismodulen ein.
    Andere Module werden mit Hilfe der Option
    --enable-module aktiviert, wobei module
    den Namen des Moduls ohne das Präfix mod_ darstellt.
    Ausserdem sind alle Unterstriche durch Bindestriche zu ersetzen. Sie
    können sich auch entscheiden, Module als "Shared
    Objects (DSOs)" zu kompilieren, welche zur Laufzeit ge- und entladen
    werden können. Dazu verwenden Sie die Option
    --enable-module=shared. Entsprechend können Sie
    Basismodule mit der Option --disable-module
    deaktivieren. Lassen Sie Vorsicht walten. wenn Sie diese Optionen verwenden,
    da configure Sie nicht warnen kann, wenn die von Ihnen
    angegebenen Module nicht existieren; die Option wird dann einfach
    ignoriert.
    

    
    Zusätzlich ist es zuweilen notwendig, das
    configure-Skript mit Extrainformationen zum Ablageort
    Ihres Compilers, Ihrer Bibliotheken oder Header-Dateien zu versorgen. Das
    tun Sie, indem Sie entweder Umgebungsvariablen oder Kommandozeilenoptionen
    an configure übergeben. Für mehr Informationen
    lesen Sie bitte die Hilfeseite zu configure.
    

    
    Um einen kurzen Eindruck zu gewinnen, welche Möglichkeiten Sie
    haben, folgt hier ein typisches Beispiel, das den Apache mit einem
    speziellen Compiler und Compilerflags für das
    Installationsverzeichnis /sk/pkg/apache kompiliert, sowie
    die beiden zusätzlichen Module mod_rewrite und
    mod_speling für späteres Laden durch den
    DSO-Mechanismus:
    

  
    
      $ CC="pgcc" CFLAGS="-O2" \
    
       ./configure --prefix=/sw/pkg/apache \
    
       --enable-rewrite=shared \
    
       --enable-speling=shared
  
    

    
    Wenn configure startet, benötigt es mehrere
    Minuten, um die Verfügbarkeit von Features auf Ihrem System zu
    prüfen und ein Makefile zu generieren, das später zur
    Kompilierung des Servers verwendet wird.
    

    
    Einzelheiten zu den vielen verschiedenen configure-Optionen finden Sie auf der Hilfeseite zu
    configure.

    Erstellen
    

    
    Nun können Sie die verschiedenen Teile, die das Apache-Paket
    bilden, einfach durch Ausführen des folgenden Befehls erstellen:
    

  
    $ make
    

    
    Seien Sie hierbei bitte geduldig, denn eine Basiskonfiguration
    benötigt ungefähr 3 Minuten auf einem Pentium III/Linux 2.2.
    System. Dies kann aber abhängig von Ihrer Hardware und der Anzahl
    der Module, die Sie aktiviert haben, sehr stark variieren.
    

    top
    

    

    Installieren
    

    
    Nun endlich installieren Sie das Package unter dem konfigurierten
    Installations-PREFIX (siehe oben: Option --prefix
    durch Aufrufen von:
    

  
    $ make install
    

    
    Wenn Sie upgraden, wird die Installation Ihre Konfigurationsdateien
    oder Dokumente nicht überschrieben.
    

    top
    

    

    Anpassen
    

    
    Als nächstes können Sie Ihren Apache HTTP Server anpassen,
    indem Sie die Konfigurationsdateien
    unterhalb von PREFIX/conf/ editieren.

    Testen
    

    
    Sie können nun Ihren Apache HTTP Server starten, indem Sie einfach
    

  
    $ PREFIX/bin/apachectl start
    

    
    ausführen.
    

    
    Danach sollten Sie Ihr erstes Dokument unter dem URL
    http://localhost/ anfordern können. Die Webseite,
    die Sie sehen, ist im DocumentRoot
    abgelegt, welches üblicherweise PREFIX/htdocs/
    ist. Den Server stoppen Sie wieder durch
    Ausführen von:
    

  
    $ PREFIX/bin/apachectl stop

    Upgrade
    

    
    Der erste Schritt beim Aktualisieren besteht darin, die
    Versionsankündigung sowie die CHANGES-Datei in der
    Quelltextdistribution zu lesen, um Änderungen zu finden, die Ihr
    System möglicherweise betreffen. Wenn Sie einen größeren
    Versionssprung durchführen (z.B. vom 1.3 auf 2.0 oder von 2.0 auf
    2.2), wird es wahrscheinlich auch größere Unterschiede in der
    Kompilier- und Laufzeitkonfiguration geben, die manuelle Nacharbeiten
    erfordern. Außerdem müssen alle Module aktualisiert
    werden, um den Änderungen der Modul-API gerecht zu werden.
    

    
    Die Aktualisierung einer Unterversion auf eine andere (z.B. von 2.0.55
    auf 2.0.57) ist einfacher. make install überschreibt
    keine der bereits existierenden Dokumente, Log- und Konfigurationsdateien.
    Ausserdem bemühen sich die Entwickler, inkompatible Änderungen
    der configure-Optionen, der Laufzeitkonfiguration sowie
    der Modul-API zu vermeiden. In den meisten Fällen sollten Sie in der
    Lage sein, den gleichen configure-Befehl, die gleiche
    Konfiguration und die gleichen Module wieder zu verwenden. (Das gilt erst
    seit Version 2.0.41 -- frühere Versionen enthielten noch inkompatible
    Änderungen).
    

    
    Um auf eine neue Unterversion zu aktualisieren, suchen Sie zunächst
    die Datei config.nice im build-Verzeichnis
    Ihrer Serverinstallation oder im Wurzelverzeichnis des Quelltextbaums
    der alten Installation. Die Datei enthält den genauen
    configure-Befehl, der verwendet wurde, um den
    Quellcode zu konfigurieren. Um jetzt von einer Version auf die
    nächste zu aktualisieren, kopieren Sie einfach die
    config.nice in das Verzeichnis der neuen Version,
    passen sie bei Bedarf an, und führen Sie sie aus:
    

    
    
      $ ./config.nice
    
      $ make
    
      $ make install
    
      $ PREFIX/bin/apachectl stop
    
      $ PREFIX/bin/apachectl start
    
    
    

    
    Sie sollten jede neue Version immer in Ihrer Umgebung
    testen, bevor Sie sie produktiv schalten. Beispielsweise können Sie
    die neue Version neben der alten installieren, indem Sie ein anderes
    --prefix und einen anderen Port wählen (durch Anpassen der
    Listen-Direktive). So
    können Sie auf eventuelle Inkompatibilitäten testen, bevor Sie
    endgültig die neue Version verwenden.

    The suEXEC feature provides users of the Apache
    HTTP Server the ability
    to run CGI and SSI programs
    under user IDs different from the user ID of the calling
    web server. Normally, when a CGI or SSI program executes, it
    runs as the same user who is running the web server.
    

    
    Used properly, this feature can reduce
    considerably the security risks involved with allowing users to
    develop and run private CGI or SSI programs. However, if suEXEC
    is improperly configured, it can cause any number of problems
    and possibly create new holes in your computer's security. If
    you aren't familiar with managing setuid root programs
    and the security issues they present, we highly recommend that
    you not consider using suEXEC.
    
  
    


    top
    

    

    Before we begin
    

    
    Before jumping head-first into this document,
    you should be aware that certain assumptions are made about you and
    the environment in which you will be using suexec.
    

    
    First, it is assumed that you are using a UNIX
    derivative operating system that is capable of
    setuid and setgid operations.
    All command examples are given in this regard. Other platforms,
    if they are capable of supporting suEXEC, may differ in their
    configuration.
    

    
    Second, it is assumed you are familiar with
    some basic concepts of your computer's security and its
    administration. This involves an understanding of
    setuid/setgid operations and the various
    effects they may have on your system and its level of
    security.
    

    
    Third, it is assumed that you are using an
    unmodified version of suEXEC code. All code
    for suEXEC has been carefully scrutinized and tested by the
    developers as well as numerous beta testers. Every precaution
    has been taken to ensure a simple yet solidly safe base of
    code. Altering this code can cause unexpected problems and new
    security risks. It is highly recommended you
    not alter the suEXEC code unless you are well versed in the
    particulars of security programming and are willing to share
    your work with the Apache HTTP Server development team for consideration.
    

    
    Fourth, and last, it has been the decision of
    the Apache HTTP Server development team to NOT make suEXEC part of
    the default installation of Apache httpd. To this end, suEXEC
    configuration requires of the administrator careful attention
    to details. After due consideration has been given to the
    various settings for suEXEC, the administrator may install
    suEXEC through normal installation methods. The values for
    these settings need to be carefully determined and specified by
    the administrator to properly maintain system security during
    the use of suEXEC functionality. It is through this detailed
    process that we hope to limit suEXEC
    installation only to those who are careful and determined
    enough to use it.
    

    
    Still with us? Yes? Good. Let's move on!
    

    top
    

    

    suEXEC Security Model
    

    
    Before we begin configuring and installing
    suEXEC, we will first discuss the security model you are about
    to implement. By doing so, you may better understand what
    exactly is going on inside suEXEC and what precautions are
    taken to ensure your system's security.
    

    
    suEXEC is based on a setuid
    "wrapper" program that is called by the main Apache HTTP Server.
    This wrapper is called when an HTTP request is made for a CGI
    or SSI program that the administrator has designated to run as
    a userid other than that of the main server. When such a
    request is made, Apache httpd provides the suEXEC wrapper with the
    program's name and the user and group IDs under which the
    program is to execute.
    

    
    The wrapper then employs the following process
    to determine success or failure -- if any one of these
    conditions fail, the program logs the failure and exits with an
    error, otherwise it will continue:
    

    
      
      
    1. 
        Is the user executing this wrapper a valid user of
        this system?

        
      
          This is to ensure that the user executing the wrapper is
          truly a user of the system.
        
      
     
      2. 

     
    2. 
        Was the wrapper called with the proper number of
        arguments?

        
      
          The wrapper will only execute if it is given the proper
          number of arguments. The proper argument format is known
          to the Apache HTTP Server. If the wrapper is not receiving
          the proper number of arguments, it is either being
          hacked, or there is something wrong with the suEXEC
          portion of your Apache httpd binary.
        
      
      
      3. 

      
    3. 
        Is this valid user allowed to run the
        wrapper?

        
      
          Is this user the user allowed to run this wrapper? Only
          one user (the Apache user) is allowed to execute this
          program.
        
      
      
      4. 

      
    4. 
        Does the target CGI or SSI program have an unsafe
        hierarchical reference?

        
      
          Does the target CGI or SSI program's path contain a leading
          '/' or have a '..' backreference? These are not allowed; the
          target CGI/SSI program must reside within suEXEC's document
          root (see --with-suexec-docroot=DIR
          below).
        
      
      
      5. 

      
    5. 
        Is the target user name valid?

        
      
          Does the target user exist?
        
      
      
      6. 

      
    6. 
        Is the target group name valid?

        
      
          Does the target group exist?
        
      
      
      7. 

      
    7. 
        Is the target user NOT superuser?


        
      
          suEXEC does not allow root
          to execute CGI/SSI programs.
        
      
      
      8. 

      
    8. 
        Is the target userid ABOVE the minimum ID
        number?

        
      
          The minimum user ID number is specified during
          configuration. This allows you to set the lowest possible
          userid that will be allowed to execute CGI/SSI programs.
          This is useful to block out "system" accounts.
        
      
      
      9. 

      
    9. 
        Is the target group NOT the superuser
        group?

        
      
          Presently, suEXEC does not allow the root
          group to execute CGI/SSI programs.
        
      
      
      10. 

      
    10. 
        Is the target groupid ABOVE the minimum ID
        number?

        
      
          The minimum group ID number is specified during
          configuration. This allows you to set the lowest possible
          groupid that will be allowed to execute CGI/SSI programs.
          This is useful to block out "system" groups.
        
      
      
      11. 

      
    11. 
        Can the wrapper successfully become the target user
        and group?

        
      
          Here is where the program becomes the target user and
          group via setuid and setgid calls. The group access list
          is also initialized with all of the groups of which the
          user is a member.
        
      
      
      12. 

      
    12. 
        Can we change directory to the one in which the target
        CGI/SSI program resides?

        
      
          If it doesn't exist, it can't very well contain files. If we
          can't change directory to it, it might as well not exist.
        
      
      
      13. 

      
    13. 
        Is the directory within the httpd webspace?

        
      
          If the request is for a regular portion of the server, is
          the requested directory within suEXEC's document root? If
          the request is for a UserDir, is the requested directory
          within the directory configured as suEXEC's userdir (see
          suEXEC's configuration options)?
        
      
      
      14. 

      
    14. 
        Is the directory NOT writable by anyone
        else?

        
      
          We don't want to open up the directory to others; only
          the owner user may be able to alter this directories
          contents.
        
      
      
      15. 

      
    15. 
        Does the target CGI/SSI program exist?

        
      
          If it doesn't exists, it can't very well be executed.
        
      
      
      16. 

      
    16. 
        Is the target CGI/SSI program NOT writable
        by anyone else?

        
      
          We don't want to give anyone other than the owner the
          ability to change the CGI/SSI program.
        
      
      
      17. 

      
    17. 
        Is the target CGI/SSI program NOT setuid or
        setgid?

        
      
          We do not want to execute programs that will then change
          our UID/GID again.
        
      
      
      18. 

      
    18. 
        Is the target user/group the same as the program's
        user/group?

        
      
          Is the user the owner of the file?
        
      
      
      19. 

      
    19. 
        Can we successfully clean the process environment
        to ensure safe operations?

        
      
          suEXEC cleans the process's environment by establishing a
          safe execution PATH (defined during configuration), as
          well as only passing through those variables whose names
          are listed in the safe environment list (also created
          during configuration).
        
      
      
      20. 

      
    20. 
        Can we successfully become the target CGI/SSI program
        and execute?

        
      
          Here is where suEXEC ends and the target CGI/SSI program begins.
        
      
      
      21. 
    
    

    
    This is the standard operation of the
    suEXEC wrapper's security model. It is somewhat stringent and
    can impose new limitations and guidelines for CGI/SSI design,
    but it was developed carefully step-by-step with security in
    mind.
    

    
    For more information as to how this security
    model can limit your possibilities in regards to server
    configuration, as well as what security risks can be avoided
    with a proper suEXEC setup, see the "Beware the Jabberwock" section of this
    document.

    Configuring & Installing
    suEXEC
    

    
    Here's where we begin the fun.
    

    
    suEXEC configuration
    options
    
    
    

    
    
      
    --enable-suexec
    

      
    This option enables the suEXEC feature which is never
      installed or activated by default. At least one
      --with-suexec-xxxxx option has to be provided
      together with the --enable-suexec option to let
      APACI accept your request for using the suEXEC feature.
    

      
    --with-suexec-bin=PATH
    

      
    The path to the suexec binary must be hard-coded
      in the server for security reasons. Use this option to override
      the default path. e.g.
      --with-suexec-bin=/usr/sbin/suexec
    

      
    --with-suexec-caller=UID
    

      
    The username under which
      httpd normally runs. This is the only user allowed to
      execute the suEXEC wrapper.
    

      
    --with-suexec-userdir=DIR
    

      
    Define to be the subdirectory under users' home
      directories where suEXEC access should be allowed. All
      executables under this directory will be executable by suEXEC
      as the user so they should be "safe" programs. If you are
      using a "simple" UserDir
      directive (ie. one without a "*" in it) this should be set to the same
      value. suEXEC will not work properly in cases where the UserDir directive points to
      a location that is not the same as the user's home directory
      as referenced in the passwd file. Default value is
      "public_html".
    
      If you have virtual hosts with a different UserDir for each,
      you will need to define them to all reside in one parent
      directory; then name that parent directory here. If
      this is not defined properly, "~userdir" cgi requests will
      not work!
    

      
    --with-suexec-docroot=DIR
    

      
    Define as the DocumentRoot set for httpd. This will be
      the only hierarchy (aside from UserDirs) that can be used for suEXEC behavior. The
      default directory is the --datadir value with the suffix
      "/htdocs", e.g. if you configure with
      "--datadir=/home/apache" the directory
      "/home/apache/htdocs" is used as document root for the
      suEXEC wrapper.
    

      
    --with-suexec-uidmin=UID
    

      
    Define this as the lowest UID allowed to be a target user
      for suEXEC. For most systems, 500 or 100 is common. Default
      value is 100.
    

      
    --with-suexec-gidmin=GID
    

      
    Define this as the lowest GID allowed to be a target
      group for suEXEC. For most systems, 100 is common and
      therefore used as default value.
    

      
    --with-suexec-logfile=FILE
    

      
    This defines the filename to which all suEXEC
      transactions and errors are logged (useful for auditing and
      debugging purposes). By default the logfile is named
      "suexec_log" and located in your standard logfile
      directory (--logfiledir).
    

      
    --with-suexec-safepath=PATH
    

      
    Define a safe PATH environment to pass to CGI
      executables. Default value is
      "/usr/local/bin:/usr/bin:/bin".
    
    
    

    
    Compiling and installing the suEXEC wrapper
    
      

      
    If you have enabled the suEXEC feature with the
      --enable-suexec option the suexec binary
      (together with httpd itself) is automatically built if you execute
      the make command.
    

      
    After all components have been built you can execute the
      command make install to install them. The binary image
      suexec is installed in the directory defined by the
      --sbindir option. The default location is
      "/usr/local/apache2/bin/suexec".
    

      
    Please note that you need root
      privileges for the installation step. In order
      for the wrapper to set the user ID, it must be installed as
      owner root and must have the setuserid
      execution bit set for file modes.
    
    

    
    Setting paranoid permissions
    
      

      
    Although the suEXEC wrapper will check to ensure that its
      caller is the correct user as specified with the
      --with-suexec-caller configure
      option, there is
      always the possibility that a system or library call suEXEC uses
      before this check may be exploitable on your system. To counter
      this, and because it is best-practise in general, you should use
      filesystem permissions to ensure that only the group httpd
      runs as may execute suEXEC.
    

      
    If for example, your web server is configured to run as:
    

      
    User www
Group webgroup
    


      
    and suexec is installed at
      "/usr/local/apache2/bin/suexec", you should run:
    

      
    
          chgrp webgroup /usr/local/apache2/bin/suexec
    
          chmod 4750 /usr/local/apache2/bin/suexec
    
      
    

      
    This will ensure that only the group httpd runs as can even
      execute the suEXEC wrapper.
    
    

    top
    

    

    Enabling & Disabling
    suEXEC
    

    
    Upon startup of httpd, it looks for the file
    suexec in the directory defined by the
    --sbindir option (default is
    "/usr/local/apache/sbin/suexec"). If httpd finds a properly
    configured suEXEC wrapper, it will print the following message
    to the error log:
    


    
    [notice] suEXEC mechanism enabled (wrapper: /path/to/suexec)

    

    
    If you don't see this message at server startup, the server is
    most likely not finding the wrapper program where it expects
    it, or the executable is not installed setuid root.
    

     
    If you want to enable the suEXEC mechanism for the first time
    and an Apache HTTP Server is already running you must kill and
    restart httpd. Restarting it with a simple HUP or USR1 signal
    will not be enough. 
    
     
    If you want to disable suEXEC you should kill and restart
    httpd after you have removed the suexec file.

    Using suEXEC
    

    
    Requests for CGI programs will call the suEXEC wrapper only if
    they are for a virtual host containing a SuexecUserGroup directive or if
    they are processed by mod_userdir.
    

    
    Virtual Hosts:
     One way to use the suEXEC
    wrapper is through the SuexecUserGroup directive in
    VirtualHost definitions.  By
    setting this directive to values different from the main server
    user ID, all requests for CGI resources will be executed as the
    User and Group defined for that <VirtualHost>. If this
    directive is not specified for a <VirtualHost> then the main server userid
    is assumed.
    

    
    User directories:
     Requests that are
     processed by mod_userdir will call the suEXEC
     wrapper to execute CGI programs under the userid of the requested
     user directory.  The only requirement needed for this feature to
     work is for CGI execution to be enabled for the user and that the
     script must meet the scrutiny of the security
     checks above.  See also the
     --with-suexec-userdir compile
     time option.

    Debugging suEXEC
    

    
    The suEXEC wrapper will write log information
    to the file defined with the --with-suexec-logfile
    option as indicated above. If you feel you have configured and
    installed the wrapper properly, have a look at this log and the
    error_log for the server to see where you may have gone astray.

    Warnings & Examples
    

    
    NOTE! This section may not be

    There are a few points of interest regarding

    suEXEC Points Of Interest
    
    
      

      
    • 
        Hierarchy limitations

        
      
          For security and efficiency reasons, all suEXEC requests
          must remain within either a top-level document root for
          virtual host requests, or one top-level personal document
          root for userdir requests. For example, if you have four
          VirtualHosts configured, you would need to structure all
          of your VHosts' document roots off of one main httpd
          document hierarchy to take advantage of suEXEC for
          VirtualHosts. (Example forthcoming.)
        
      
      
      • 

      
    • 
        suEXEC's PATH environment variable

        
      
          This can be a dangerous thing to change. Make certain
          every path you include in this define is a
          trusted directory. You don't want to
          open people up to having someone from across the world
          running a trojan horse on them.
        
      
      
      • 

      
    • 
        Altering the suEXEC code

        
      
          Again, this can cause Big Trouble if you
          try this without knowing what you are doing. Stay away
          from it if at all possible.

    Apache HTTPD supports content negotiation as described in
    the HTTP/1.1 specification. It can choose the best
    representation of a resource based on the browser-supplied
    preferences for media type, languages, character set and
    encoding. It also implements a couple of features to give
    more intelligent handling of requests from browsers that send
    incomplete negotiation information.
    

    
    Content negotiation is provided by the
    mod_negotiation module, which is compiled in
    by default.

    About Content Negotiation
    

    
    A resource may be available in several different
    representations. For example, it might be available in
    different languages or different media types, or a combination.
    One way of selecting the most appropriate choice is to give the
    user an index page, and let them select. However it is often
    possible for the server to choose automatically. This works
    because browsers can send, as part of each request, information
    about what representations they prefer. For example, a browser
    could indicate that it would like to see information in French,
    if possible, else English will do. Browsers indicate their
    preferences by headers in the request. To request only French
    representations, the browser would send
    


    Accept-Language: fr
    

    
    Note that this preference will only be applied when there is
    a choice of representations and they vary by language.
    

    
    As an example of a more complex request, this browser has
    been configured to accept French and English, but prefer
    French, and to accept various media types, preferring HTML over
    plain text or other text types, and preferring GIF or JPEG over
    other media types, but also allowing any other media type as a
    last resort:
    


    
  Accept-Language: fr; q=1.0, en; q=0.5
    
  Accept: text/html; q=1.0, text/*; q=0.8, image/gif; q=0.6, image/jpeg; q=0.6, image/*; q=0.5, */*; q=0.1

    

    
    httpd supports 'server driven' content negotiation, as
    defined in the HTTP/1.1 specification. It fully supports the
    Accept, Accept-Language,
    Accept-Charset and Accept-Encoding
    request headers. httpd also supports 'transparent'
    content negotiation, which is an experimental negotiation
    protocol defined in RFC 2295 and RFC 2296. It does not offer
    support for 'feature negotiation' as defined in these RFCs.
    

    
    A resource is a conceptual entity
    identified by a URI (RFC 2396). An HTTP server like Apache HTTP Server
    provides access to representations of the
    resource(s) within its namespace, with each representation in
    the form of a sequence of bytes with a defined media type,
    character set, encoding, etc. Each resource may be associated
    with zero, one, or more than one representation at any given
    time. If multiple representations are available, the resource
    is referred to as negotiable and each of its
    representations is termed a variant. The ways
    in which the variants for a negotiable resource vary are called
    the dimensions of negotiation.
    

    top
    

    

    Negotiation in httpd
    

    
    In order to negotiate a resource, the server needs to be
    given information about each of the variants. This is done in
    one of two ways:
    

    
      
      
    • Using a type map (i.e., a *.var
      file) which names the files containing the variants
      explicitly, or
      • 

      
    • Using a 'MultiViews' search, where the server does an
      implicit filename pattern match and chooses from among the
      results.
      • 
    
    

   
    Using a type-map file
    

    
    A type map is a document which is associated with the handler
    named type-map (or, for backwards-compatibility with
    older httpd configurations, the MIME-type
    application/x-type-map). Note that to use this
    feature, you must have a handler set in the configuration that
    defines a file suffix as type-map; this is best done
    with
    


    AddHandler type-map .var
    


    
    in the server configuration file.
    

    
    Type map files should have the same name as the resource
    which they are describing, followed by the extension
    .var. In the examples shown below, the resource is
    named foo, so the type map file is named
    foo.var.
    

    
    This file should have an entry for each available
    variant; these entries consist of contiguous HTTP-format header
    lines. Entries for different variants are separated by blank
    lines. Blank lines are illegal within an entry. It is
    conventional to begin a map file with an entry for the combined
    entity as a whole (although this is not required, and if
    present will be ignored). An example map file is shown below.
    

    
    URIs in this file are relative to the location of the type map
    file. Usually, these files will be located in the same directory as
    the type map file, but this is not required. You may provide
    absolute or relative URIs for any file located on the same server as
    the map file.
    


    
  URI: foo
    

    
  URI: foo.en.html
    
  Content-type: text/html
    
  Content-language: en
    

    
  URI: foo.fr.de.html
    
  Content-type: text/html;charset=iso-8859-2
    
  Content-language: fr, de
    

    

    
    Note also that a typemap file will take precedence over the
    filename's extension, even when Multiviews is on. If the
    variants have different source qualities, that may be indicated
    by the "qs" parameter to the media type, as in this picture
    (available as JPEG, GIF, or ASCII-art): 
    


    
  URI: foo
    

    
  URI: foo.jpeg
    
  Content-type: image/jpeg; qs=0.8
    

    
  URI: foo.gif
    
  Content-type: image/gif; qs=0.5
    

    
  URI: foo.txt
    
  Content-type: text/plain; qs=0.01
    

    

    
    qs values can vary in the range 0.000 to 1.000. Note that
    any variant with a qs value of 0.000 will never be chosen.
    Variants with no 'qs' parameter value are given a qs factor of
    1.0. The qs parameter indicates the relative 'quality' of this
    variant compared to the other available variants, independent
    of the client's capabilities. For example, a JPEG file is
    usually of higher source quality than an ASCII file if it is
    attempting to represent a photograph. However, if the resource
    being represented is an original ASCII art, then an ASCII
    representation would have a higher source quality than a JPEG
    representation. A qs value is therefore specific to a given
    variant depending on the nature of the resource it
    represents.
    

    
    The full list of headers recognized is available in the mod_negotiation
    typemap documentation.
    



    Multiviews
    

    
    MultiViews is a per-directory option, meaning it
    can be set with an Options
    directive within a <Directory>, <Location> or <Files> section in
    httpd.conf, or (if AllowOverride is properly set) in
    .htaccess files. Note that Options All
    does not set MultiViews; you have to ask for it by
    name.
    

    
    The effect of MultiViews is as follows: if the
    server receives a request for /some/dir/foo, if
    /some/dir has MultiViews enabled, and
    /some/dir/foo does not exist, then the
    server reads the directory looking for files named foo.*, and
    effectively fakes up a type map which names all those files,
    assigning them the same media types and content-encodings it
    would have if the client had asked for one of them by name. It
    then chooses the best match to the client's requirements.
    

    
    MultiViews may also apply to searches for the file
    named by the DirectoryIndex directive, if the
    server is trying to index a directory. If the configuration files
    specify
    

    DirectoryIndex index
    

    
    then the server will arbitrate between index.html
    and index.html3 if both are present. If neither
    are present, and index.cgi is there, the server
    will run it.
    

    
    If one of the files found when reading the directory does not
    have an extension recognized by mod_mime to designate
    its Charset, Content-Type, Language, or Encoding, then the result
    depends on the setting of the MultiViewsMatch directive.  This
    directive determines whether handlers, filters, and other
    extension types can participate in MultiViews negotiation.

    The Negotiation Methods
    

    
    After httpd has obtained a list of the variants for a given
    resource, either from a type-map file or from the filenames in
    the directory, it invokes one of two methods to decide on the
    'best' variant to return, if any. It is not necessary to know
    any of the details of how negotiation actually takes place in
    order to use httpd's content negotiation features. However the
    rest of this document explains the methods used for those
    interested. 
    

    
    There are two negotiation methods:
    

    
      
      
    1. Server driven negotiation with the httpd
      algorithm is used in the normal case. The httpd
      algorithm is explained in more detail below. When this
      algorithm is used, httpd can sometimes 'fiddle' the quality
      factor of a particular dimension to achieve a better result.
      The ways httpd can fiddle quality factors is explained in
      more detail below.
      2. 

      
    2. Transparent content negotiation is used
      when the browser specifically requests this through the
      mechanism defined in RFC 2295. This negotiation method gives
      the browser full control over deciding on the 'best' variant,
      the result is therefore dependent on the specific algorithms
      used by the browser. As part of the transparent negotiation
      process, the browser can ask httpd to run the 'remote
      variant selection algorithm' defined in RFC 2296.
      3. 
    
    


    Dimensions of Negotiation
    

    
    
      
      
    
        Dimension

        Notes
      
    

      
    
        Media Type

        Browser indicates preferences with the Accept
        header field. Each item can have an associated quality factor.
        Variant description can also have a quality factor (the "qs"
        parameter).
      
    

      
    
        Language

        Browser indicates preferences with the
        Accept-Language header field. Each item can have
        a quality factor. Variants can be associated with none, one or
        more than one language.
      
    

      
    
        Encoding

        Browser indicates preference with the
        Accept-Encoding header field. Each item can have
        a quality factor.
      
    

      
    
        Charset

        Browser indicates preference with the
        Accept-Charset header field. Each item can have a
        quality factor. Variants can indicate a charset as a parameter
        of the media type.
      
    
    
    



    httpd Negotiation Algorithm
    

    
    httpd can use the following algorithm to select the 'best'
    variant (if any) to return to the browser. This algorithm is
    not further configurable. It operates as follows:
    

    
      
      
    1. First, for each dimension of the negotiation, check the
      appropriate Accept* header field and assign a
      quality to each variant. If the Accept* header for
      any dimension implies that this variant is not acceptable,
      eliminate it. If no variants remain, go to step 4.
      2. 

      
    2. 
        Select the 'best' variant by a process of elimination. Each
        of the following tests is applied in order. Any variants
        not selected at each test are eliminated. After each test,
        if only one variant remains, select it as the best match
        and proceed to step 3. If more than one variant remains,
        move on to the next test.

        
        
          
      1. Multiply the quality factor from the Accept
          header with the quality-of-source factor for this variants
          media type, and select the variants with the highest
          value.
        2. 

          
      2. Select the variants with the highest language quality
          factor.
        3. 

          
      3. Select the variants with the best language match,
          using either the order of languages in the
          Accept-Language header (if present), or else
          the order of languages in the LanguagePriority
          directive (if present).
        4. 

          
      4. Select the variants with the highest 'level' media
          parameter (used to give the version of text/html media
          types).
        5. 

          
      5. Select variants with the best charset media
          parameters, as given on the Accept-Charset
          header line.  Charset ISO-8859-1 is acceptable unless
          explicitly excluded. Variants with a text/*
          media type but not explicitly associated with a particular
          charset are assumed to be in ISO-8859-1.
        6. 

          
      6. Select those variants which have associated charset
          media parameters that are not ISO-8859-1. If
          there are no such variants, select all variants
          instead.
        7. 

          
      7. Select the variants with the best encoding. If there
          are variants with an encoding that is acceptable to the
          user-agent, select only these variants. Otherwise if
          there is a mix of encoded and non-encoded variants,
          select only the unencoded variants. If either all
          variants are encoded or all variants are not encoded,
          select all variants.
        8. 

          
      8. Select the variants with the smallest content
          length.
        9. 

          
      9. Select the first variant of those remaining. This
          will be either the first listed in the type-map file, or
          when variants are read from the directory, the one whose
          file name comes first when sorted using ASCII code
          order.
        10. 
        
      
      
      3. 

      
    3. The algorithm has now selected one 'best' variant, so
      return it as the response. The HTTP response header
      Vary is set to indicate the dimensions of
      negotiation (browsers and caches can use this information when
      caching the resource).  End.
      4. 

      
    4. To get here means no variant was selected (because none
      are acceptable to the browser). Return a 406 status (meaning
      "No acceptable representation") with a response body
      consisting of an HTML document listing the available
      variants. Also set the HTTP Vary header to
      indicate the dimensions of variance.
      5.

    Fiddling with Quality
    Values
    

    
    httpd sometimes changes the quality values from what would
    be expected by a strict interpretation of the httpd
    negotiation algorithm above. This is to get a better result
    from the algorithm for browsers which do not send full or
    accurate information. Some of the most popular browsers send
    Accept header information which would otherwise
    result in the selection of the wrong variant in many cases. If a
    browser sends full and correct information these fiddles will not
    be applied.
    


    Media Types and Wildcards
    

    
    The Accept: request header indicates preferences
    for media types. It can also include 'wildcard' media types, such
    as "image/*" or "*/*" where the * matches any string. So a request
    including:
    


    Accept: image/*, */*
    

    
    would indicate that any type starting "image/" is acceptable,
    as is any other type.
    Some browsers routinely send wildcards in addition to explicit
    types they can handle. For example:
    


    
  Accept: text/html, text/plain, image/gif, image/jpeg, */*

    
    
    The intention of this is to indicate that the explicitly listed
    types are preferred, but if a different representation is
    available, that is ok too.  Using explicit quality values,
    what the browser really wants is something like:
    

    
  Accept: text/html, text/plain, image/gif, image/jpeg, */*; q=0.01

    
    
    The explicit types have no quality factor, so they default to a
    preference of 1.0 (the highest). The wildcard */* is given a
    low preference of 0.01, so other types will only be returned if
    no variant matches an explicitly listed type.
    

    
    If the Accept: header contains no q
    factors at all, httpd sets the q value of "*/*", if present, to
    0.01 to emulate the desired behavior. It also sets the q value of
    wildcards of the format "type/*" to 0.02 (so these are preferred
    over matches against "*/*". If any media type on the
    Accept: header contains a q factor, these special
    values are not applied, so requests from browsers which
    send the explicit information to start with work as expected.
    



    Language Negotiation Exceptions
    

    
    New in httpd 2.0, some exceptions have been added to the
    negotiation algorithm to allow graceful fallback when language
    negotiation fails to find a match.
    

    
    When a client requests a page on your server, but the server
    cannot find a single page that matches the
    Accept-language sent by
    the browser, the server will return either a "No Acceptable
    Variant" or "Multiple Choices" response to the client.  To avoid
    these error messages, it is possible to configure httpd to ignore
    the Accept-language in these cases and provide a
    document that does not explicitly match the client's request.  The
    ForceLanguagePriority
    directive can be used to override one or both of these error
    messages and substitute the servers judgement in the form of the
    LanguagePriority
    directive.
    

    
    The server will also attempt to match language-subsets when no
    other match can be found.  For example, if a client requests
    documents with the language en-GB for British
    English, the server is not normally allowed by the HTTP/1.1
    standard to match that against a document that is marked as simply
    en.  (Note that it is almost surely a configuration
    error to include en-GB and not en in the
    Accept-Language header, since it is very unlikely
    that a reader understands British English, but doesn't understand
    English in general.  Unfortunately, many current clients have
    default configurations that resemble this.)  However, if no other
    language match is possible and the server is about to return a "No
    Acceptable Variants" error or fallback to the LanguagePriority, the server
    will ignore the subset specification and match en-GB
    against en documents.  Implicitly, httpd will add
    the parent language to the client's acceptable language list with
    a very low quality value.  But note that if the client requests
    "en-GB; q=0.9, fr; q=0.8", and the server has documents
    designated "en" and "fr", then the "fr" document will be returned.
    This is necessary to maintain compliance with the HTTP/1.1
    specification and to work effectively with properly configured
    clients.
    

    
    In order to support advanced techniques (such as cookies or
    special URL-paths) to determine the user's preferred language,
    since httpd 2.0.47 mod_negotiation recognizes
    the environment variable
    prefer-language. If it exists and contains an
    appropriate language tag, mod_negotiation will
    try to select a matching variant. If there's no such variant,
    the normal negotiation process applies.
    

    
    Example
    SetEnvIf Cookie "language=(.+)" prefer-language=$1
Header append Vary cookie

    Extensions to Transparent Content
Negotiation
    


    httpd extends the transparent content negotiation protocol (RFC
2295) as follows. A new {encoding ..} element is used in
variant lists to label variants which are available with a specific
content-encoding only. The implementation of the RVSA/1.0 algorithm
(RFC 2296) is extended to recognize encoded variants in the list, and
to use them as candidate variants whenever their encodings are
acceptable according to the Accept-Encoding request
header. The RVSA/1.0 implementation does not round computed quality
factors to 5 decimal places before choosing the best variant.
    

    top
    

    

    Note on hyperlinks and naming conventions
    

    
    If you are using language negotiation you can choose between
    different naming conventions, because files can have more than
    one extension, and the order of the extensions is normally
    irrelevant (see the mod_mime documentation
    for details).
    

    
    A typical file has a MIME-type extension (e.g.,
    html), maybe an encoding extension (e.g.,
    gz), and of course a language extension
    (e.g., en) when we have different
    language variants of this file.
    

    
    Examples:
    

    
      
      
    • foo.en.html
      • 

      
    • foo.html.en
      • 

      
    • foo.en.html.gz
      • 
    
    

    
    Here some more examples of filenames together with valid and
    invalid hyperlinks:
    

    
    
      
      
    
        Filename

        Valid hyperlink

        Invalid hyperlink
      
    

      
    
        foo.html.en

        foo
    
         foo.html    		

        -
      
    

      
    
        foo.en.html

        foo

        foo.html
      
    

      
    
        foo.html.en.gz

        foo
    
         foo.html    		

        foo.gz
    
         foo.html.gz    		
      
    

      
    
        foo.en.html.gz

        foo

        foo.html
    
         foo.html.gz
    
         foo.gz    		
      
    

      
    
        foo.gz.html.en

        foo
    
         foo.gz
    
         foo.gz.html    		

        foo.html
      
    

      
    
        foo.html.gz.en

        foo
    
         foo.html
    
         foo.html.gz    		

        foo.gz
      
    
    
    

    
    Looking at the table above, you will notice that it is always
    possible to use the name without any extensions in a hyperlink
    (e.g., foo). The advantage is that you
    can hide the actual type of a document rsp. file and can change
    it later, e.g., from html to
    shtml or cgi without changing any
    hyperlink references.
    

    
    If you want to continue to use a MIME-type in your
    hyperlinks (e.g. foo.html) the language
    extension (including an encoding extension if there is one)
    must be on the right hand side of the MIME-type extension
    (e.g., foo.html.en).

    Note on Caching
    

    
    When a cache stores a representation, it associates it with
    the request URL. The next time that URL is requested, the cache
    can use the stored representation. But, if the resource is
    negotiable at the server, this might result in only the first
    requested variant being cached and subsequent cache hits might
    return the wrong response. To prevent this, httpd normally
    marks all responses that are returned after content negotiation
    as non-cacheable by HTTP/1.0 clients. httpd also supports the
    HTTP/1.1 protocol features to allow caching of negotiated
    responses.
    

    
    For requests which come from a HTTP/1.0 compliant client
    (either a browser or a cache), the directive CacheNegotiatedDocs can be
    used to allow caching of responses which were subject to
    negotiation. This directive can be given in the server config or
    virtual host, and takes no arguments. It has no effect on requests
    from HTTP/1.1 clients.
    

    
    For HTTP/1.1 clients, httpd sends a Vary HTTP
    response header to indicate the negotiation dimensions for the
    response.  Caches can use this information to determine whether a
    subsequent request can be served from the local copy.  To
    encourage a cache to use the local copy regardless of the
    negotiation dimensions, set the force-no-vary environment variable.

    ウェブサーバを効果的に管理するためには、サーバの活動やパフォーマンス、
    今発生しているかもしれない問題に関するフィードバックを得ることが必要です。
    Apache HTTP サーバには非常に包括的で柔軟なロギング機能があります。
    この文書はロギング機能の設定の仕方と、ログに何が書かれているかを
    理解するための方法を説明します。

    セキュリティに関する警告
    

    
    Apache がログファイルを書いているディレクトリに書き込める人は、
    ほぼ確実にサーバが起動された uid へのアクセスを手に入れることができます。
    そして、それは通常は root ユーザです。
    ちゃんと結果を考えることなく、そのディレクトリへの
    書き込み権限を与えないでください。詳しくは
    セキュリティのこつの文書を
    読んでください。
    

    
    加えて、ログファイルにはクライアントからの情報がそのまま、
    エスケープされることなく書かれています。ですから、悪意のある
    クライアントがログファイルに制御文字を挿入することができます。
    生のログを扱うときは注意してください。

    エラーログ
    
    
    
    関連モジュール関連ディレクティブ
    

    
    ErrorLog ディレクティブにより
    名前と場所が決まるサーバのエラーログは、一番重要なログファイルです。
    Apache の診断情報はここに送られ、リクエストを処理しているときに
    発生したエラーはすべてここに記録されます。サーバを起動したときや、
    サーバの動作に問題が起こったときは、一番最初に調べるべき
    ところです。間違いの詳細や修正方法がそこに書かれていることが
    よくあります。
    

    
    エラーログは普通はファイルに書かれます (通常 Unix システムでは
    error_log、Windows と OS/2 では error.log)。
    Unix システムではエラーを syslog や
    パイプでプログラムに送る ことができます。
    

    
    エラーログの書式は比較的自由度の高いもので、説明的に書かれています。
    ただし、いくつかの情報はほとんどのエラーログのエントリにあります。
    例えば、代表的なものに次のようなメッセージがあります。
    

    
    
      [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1]
      client denied by server configuration:
      /export/home/live/ap/htdocs/test
    
    

    
    ログエントリの最初の項目はメッセージの日付と時刻です。
    二つめの項目は報告されているエラーの重要度です。
    LogLevel で重要度のレベルを
    制限することによりエラーログに送られるエラーの種類を制御することが
    できます。三つ目の項目はエラーを発生させたクライアントの IP アドレス
    です。残りはメッセージで、この場合はサーバがクライアントのアクセスを
    拒否するように設定されている、ということを示しています。
    サーバはリクエストされた文書の (ウェブのパスではなく) ファイルシステムの
    パスを報告します。
    

    
    非常に広範囲のメッセージがエラーログに現れます。たいていのものは
    上の例のような感じです。エラーログには CGI スクリプトのデバッグ
    出力も書かれます。CGI スクリプトが stderr に書いた
    すべての情報は直接エラーログにコピーされます。
    

    
    情報を追加したり削除したりしてエラーログをカスタマイズすることは
    できません。しかし、リクエストに対するエラーログのエントリは、
    対応するエントリがアクセスログにあります。
    例えば、上の例のエントリはアクセスログのステータスコード 403 の
    エントリに対応します。アクセスログはカスタマイズ可能ですので、
    そちらを使うことによりエラーの状況に関する情報をより多く
    手に入れることができます。
    

    
    テストの最中は、問題が発生しているかどうかを見るために、
    常にエラーログを監視するのが役に立つ場合がよくあります。
    Unix システムでは、次のものを使うことができます。
    

    
    
      tail -f error_log
    
    
  
    top
    

    

    アクセスログ
    
    

    
    関連モジュール関連ディレクティブ
    

    
    サーバアクセスログはサーバが処理をしたすべてのリクエストを
    記録します。アクセスログの場所と内容は CustomLog
    ディレクティブにより決まります。ログの内容の選択を簡潔にするために
    LogFormat
    ディレクティブを使用することができます。このセクションはアクセスログに
    情報を記録するためのサーバの設定方法を説明します。
    

    
    もちろん、アクセスログに情報を蓄積することはログ管理の
    始まりに過ぎません。次の段階は有用な統計を取るためにこの情報を
    解析することです。一般的なログ解析はこの文書の範囲外で、
    ウェブサーバ自身の仕事というわけでもありません。この話や、
    ログ解析を行なうアプリケーションの情報を得るには、
    Open Directory を調べてください。
    

    
    いろんなバージョンの Apache httpd が mod_log_config,
    mod_log_agent, TransferLog ディレクティブといった、
    他のモジュールやディレクティブを使ってアクセスのロギングを
    制御してきました。今では、CustomLog がすべての古い
    ディレクティブの機能を含むようになっています。
    

    
    アクセスログの書式は非常に柔軟な設定が可能です。
    書式は C の printf(1) フォーマット文字列に非常に似た
    フォーマット文字列
    により指定されます。いくつか次の節で例を示します。
    フォーマット文字列に使用できる内容の一覧は mod_log_config の文書
    を見てください。
    

    
    Common Log Format
    
      

      
    アクセスログのよくある設定に以下のものがあります。
    

      
    
        LogFormat "%h %l %u %t \"%r\" %>s %b" common
    
         CustomLog logs/access_log common
      
    

      
    これは、ニックネーム common を定義し、
      ログのフォーマット文字列の一つと関連付けます。フォーマット文字列は
      パーセントディレクティブからなり、それぞれのパーセントディレクティブは
      サーバにどの情報をロギングするかを指示します。フォーマット文字列に
      文字をそのまま入れることもでき、それらはログの出力に直接コピーされます。
      そこに引用文字 (") を書くときは、
      フォーマット文字列の最後として解釈
      されることを防ぐためにバックスラッシュでエスケープする必要があります。
      フォーマット文字列には改行用の "\n"、タブ用の
      "\t" という特別な制御文字も含めることができます。
    

      
    CustomLog ディレクティブは
      既に定義された
      ニックネーム を使って新しいログファイルを設定します。
      アクセスログのファイル名はスラッシュで始まらない限り、
      ServerRoot からの相対パスとして
      扱われます。
    

      
    上の設定は Common Log Format (CLF) と呼ばれる形式で
      ログエントリを書きます。この標準の形式は異なるウェブサーバの多くが
      生成することができ、多くのログ解析プログラムが読みこむことができます。
      CLF により生成されたログファイルのエントリは以下のようになります:
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
      
    

      
    このログエントリのそれぞれの部分の意味は以下で説明します。
    

      
    
	
    127.0.0.1 (%h)
    

	
    これはサーバへリクエストをしたクライアント (リモートホスト)
	の IP アドレスです。HostnameLookups が
	On の場合は、サーバはホスト名を調べて、
	IP アドレスが書かれているところに記録します。しかし、この設定は
	サーバをかなり遅くするので、あまりお勧めできません。
	そうではなく、logresolve の
	ようなログの後処理を行なうプログラムでホスト名を調べるのが良いでしょう。
	ここに報告される IP アドレスは必ずしもユーザが使っているマシンの
	ものであるとは限りません。ユーザとサーバの間にプロキシサーバが
	あれば、このアドレスは元のマシンのものではなく、プロキシの
	アドレスになります。
    

	
    - (%l)
    

	
    出力中の「ハイフン」は要求された情報が手に入らなかったということを
	意味します。この場合、取得できなかった情報はクライアントのマシンの
	identd により決まる RFC 1413 のクライアントの
	アイデンティティです。この情報はあまり信用することができず、
	しっかりと管理された内部ネットワークを除いては使うべきではありません。
	Apache は IdentityCheck が
	On になっていない限り、この情報を得ようとすらしません。
    

	
    frank (%u)
    

	
    これは HTTP 認証による、ドキュメントをリクエストした人の
	ユーザ ID です。CGI スクリプトには通常同じ値が REMOTE_USER
	環境変数として与えられます。リクエストのステータスコード
	(以下を参照) が 401 であった場合は、ユーザは認証に失敗しているので、
	この値は信用できません。ドキュメントがパスワードで保護されていない
	場合は、この部分は前のものと同じように "-" に
	なります。
    

	
    [10/Oct/2000:13:55:36 -0700]
	(%t)
    

	
    
	  サーバがリクエストを受け取った時刻です。書式は:

	    
    
	      [day/month/year:hour:minute:second zone]
    
	       day = 2*digit
    
	       month = 3*letter
    
	       year = 4*digit
    
	       hour = 2*digit
    
	       minute = 2*digit
    
	       second = 2*digit
    
	       zone = (`+' | `-') 4*digit    
	    
    
	  ログのフォーマット文字列に %{format}t を
	  指定することで、別の形式で時刻を表示させることもできます。
	  このとき、format は C の標準ライブラリの
	  strftime(3) の形式になります。
	
    

	
    "GET /apache_pb.gif HTTP/1.0"
	(\"%r\")
    

	
    クライアントからのリクエストが二重引用符の中に示されています。
	リクエストには多くの有用な情報があります。まず、この場合クライアントが
	使ったメソッドは GET です。次に、クライアントは
	リソース /apache_pb.gif を要求しました。そして、
	クライアントはプロトコル HTTP/1.0 を使用しました。
	リクエストの各部分を独立にログ収集することもできます。例えば、
	フォーマット文字列 "%m %U%q %H" は
	メソッド、パス、クエリ文字列、プロトコルをログ収集し、
	結局 "%r" とまったく同じ出力になります。
    

	
    200 (%>s)
    

	
    サーバがクライアントに送り返すステータスコードです。
	この情報は、リクエストが成功応答 (2 で始まるコード) であったか、
	リダイレクション (3 で始まるコード) であったか、クライアントによる
	エラー (4 で始まるコード) であったか、サーバのエラー (5 で始まるコード)
	であったか、を表すので、非常に大切です。ステータスコードの
	完全なリストは HTTP
	規格 (RFC2616 第 10 節) にあります。
    

	
    2326 (%b)
    

	
    この最後の部分はクライアントに送信されたオブジェクトの、
	応答ヘッダを除いたサイズを表します。コンテントがクライアントに送られなかった
	場合は、この値は "-" になります。コンテントが無い場合に
	"0" をログ収集するには、%b ではなく
	%B を使ってください。
    

      
    
    

    
    Combined Log Format
    
      

      
    もう一つのよく使われる書式は Combined Log Format と呼ばれています。
      以下のようにして使うことができます。
    

      
    
        LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
        \"%{User-agent}i\"" combined
    
         CustomLog log/access_log combined
      
    

      
    この書式の最初の方は Common Log Format とまったく同じで、最後に
      二つ追加のエントリがあります。追加のエントリはパーセントディレクティブ
      %{header}i を使っています。ここで
      header は HTTP のリクエストヘッダのどれかです。この書式による
      アクセスログは以下のような感じになります:
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
        "http://www.example.com/start.html" "Mozilla/4.08 [en]
        (Win98; I ;Nav)"
      
    

      
    追加のエントリは:
    

      
    
	
    "http://www.example.com/start.html"
	(\"%{Referer}i\")
    

	
    "Referer" (意図的な綴り間違い) HTTP リクエストヘッダです。
	これはクライアントが報告してくる参照元のサイトを表します。
	(この場合は、/apache_pb.gif にリンクしているか、
	それを含んでいるページです)。
    

	
    "Mozilla/4.08 [en] (Win98; I ;Nav)"
	(\"%{User-agent}i\")
    

	
    User-Agent HTTP リクエストヘッダです。これはクライアントのブラウザが
	自分自身のことを報告してくる情報です。
    
      
    
    

    
    複数のアクセスログ
    
      

    
    複数のアクセスログは単に設定ファイルに複数の CustomLog
    ディレクティブを書くことで作成されます。例えば、以下のディレクティブは
    三つのアクセスログを作ります。最初のものは基本的な CLF の情報で、
    二つ目と三つ目は referer とブラウザの情報です。最後二つの
    CustomLog は
    ReferLog ディレクティブと
    AgentLog ディレクティブの効果をまねる方法を示しています。
    

      
    
        LogFormat "%h %l %u %t \"%r\" %>s %b" common
    
        CustomLog logs/access_log common
    
        CustomLog logs/referer_log "%{Referer}i -> %U"
    
        CustomLog logs/agent_log "%{User-agent}i"
      
    

    
    この例は LogFormat で
    ニックネームを定義する必要がない、
    ということも示しています。ニックネームの代わりに、
    CustomLog ディレクティブに
    直接ログの書式を指定することができます。
    
    

    
    条件付きログ
    
      

    
    クライアントのリクエストの特徴に基づいてアクセスログにエントリの
    一部をロギングしない方が便利なことがあります。これは 環境変数 の補助により簡単に実現できます。まず、
    リクエストが何らかの条件に合うということを表すために環境変数が
    設定される必要があります。これは通常は SetEnvIf により
    行なわれます。そして、CustomLog ディレクティブの
    env= 節を使って環境変数が設定されているリクエストを
    含めたり排除したりすることができます。いくつか例を挙げます:
    

      
    
        # Mark requests from the loop-back interface
    
        SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog
    
        # Mark requests for the robots.txt file
    
        SetEnvIf Request_URI "^/robots\.txt$" dontlog
    
        # Log what remains
    
        CustomLog logs/access_log common env=!dontlog
      
    

    
    他の例として、英語を話す人からのリクエストとそれ以外の人からのリクエストを
    分けたい、という場合を考えてみてください。
    

      
    
        SetEnvIf Accept-Language "en" english
    
        CustomLog logs/english_log common env=english
    
        CustomLog logs/non_english_log common env=!english
      
    

    
    ここまででは条件付きロギングが非常に強力で柔軟であることを示してきましたが、
    それがログの内容を制御する唯一の方法というわけではありません。ログファイルは
    サーバの活動の完全な記録である方がより役に立ちます。単純にログファイルを
    後処理して、考慮したくないログを削除する方が簡単であることがよくあります。
    
    
  
    top
    

    

    ログの交替
    
    

    
    普通の負荷のサーバでさえ、ログファイルに保存される情報の量は
    膨大になります。アクセスログのファイルは普通 10,000 リクエスト毎に
    1 MB 以上増えます。ですから、既存のログを移動したり、削除したりして、
    定期的にログを交替させることが必要になります。これはサーバの実行中には
    行なえません。というのは、Apache はファイルが open されている間は
    ずっと古いログファイルに書き続けるからです。
    新しいログファイルを open できるように、ログファイルが移動されたり
    削除された後に、サーバを再起動する
    必要があります。
    

    
    優雅な 再起動を行なうことで、サーバは既存のコネクションや
    処理待ちのコネクションを失うことなく新しいログファイルを open させる
    ことができます。しかし、これを実現するために、サーバは古いリクエストを
    扱っている間は古いログファイルに書き続ける必要があります。
    ですから、再起動の後ではログファイルの処理を始める前に、しばらく待たなければ
    なりません。単にログを交替させて、ディスクの節約のために古いログを
    圧縮する普通のシナリオは:
    

    
    
      mv access_log access_log.old
    
      mv error_log error_log.old
    
      apachectl graceful
    
      sleep 600
    
      gzip access_log.old error_log.old
    
    

    
    ログの交替をするもう一つの方法はパイプ経由のログを使うもので、次の節で説明されています。
    
  
    top
    

    

    パイプ経由のログ
    
    

    
    Apache httpd はエラーログとアクセスログをファイルに直接書く代わりに、
    パイプを通して別のプログラムに書き出すことができます。
    この機能により、主サーバにコードを追加することなく
    ロギングの柔軟性が非常に高まっています。パイプにログを書くためには、
    単にファイル名をパイプ文字 "|" に置き換え、その続きに
    標準入力からログのエントリを受けとる実行プログラムの名前を書くだけです。
    Apache はパイプ経由のログ用のプロセスをサーバの起動時に実行し、
    サーバの実行中にそのプログラムがクラッシュしたときはそれを再び
    実行します。(この最後の機能がこの技術が「信頼性のあるパイプ経由のロギング」
    と呼ばれている理由です。)
    

    
    パイプ経由のログ用のプロセスは Apache httpd の親プロセスから起動され、
    そのプロセスのユーザ ID を継承します。これは、パイプ経由のログ用の
    プログラムは普通 root として実行されることを意味します。
    ですから、プログラムを簡単で安全に保つことが非常に重要です。
    

    
    パイプ経由のログの重要な利用法は、サーバの再起動なしでログの交替を
    することです。Apache HTTP サーバにはこのための  rotatelogs と呼ばれる簡単な
    プログラムが付属しています。たとえば、24 時間毎にログを交替させるには、
    以下のものを使うことができます:
    

    
    
      CustomLog "|/usr/local/apache/bin/rotatelogs
      /var/log/access_log 86400" common
    
    

    
    パイプの先で呼ばれるコマンド全体が引用符で囲まれていることに注目して
    ください。この例はアクセスログを使っていますが、エラーログにも同じ技術を
    使うことができます。
    

    
    似ているけれど、よりずっと柔軟な
    cronolog というログ交替用の
    プログラムが外部のサイトにあります。
    

    
    条件付きロギングと同様、パイプ経由のログは非常に強力な
    道具ですが、オフラインの後処理のような、より簡単な解決方法があるときは
    使わない方が良いでしょう。
    
  
    top
    

    

    バーチャルホスト
    
    

    
    多くの バーチャルホスト のあるサーバを実行している
    ときは、ログファイルの扱い方にいくつかの方法があります。
    まず、単独のホストのみのサーバとまったく同じようにログを使うことができます。
    ロギングディレクティブを主サーバのコンテキストの
    <VirtualHost> セクションの外に置くことで、
    すべてのログを同じアクセスログとエラーログにログ収集することができます。
    この手法では個々のバーチャルホストの統計を簡単にとることはできません。
    

    
    CustomLog や
    ErrorLog ディレクティブが
    <VirtualHost> の中に
    置かれた場合は、そのバーチャル
    ホストへのすべてのリクエストやエラーがそこで指定されたファイルにのみ
    ログ収集されます。ロギングディレクティブのないバーチャルホストは
    依然としてリクエストが主サーバのログに送られます。この手法は少ない
    バーチャルホストに対しては非常に有用ですが、ホストの数が非常に多くなると
    管理が大変になります。さらに、ファイル記述子の限界の問題を起こすことが
    あります。
    

    
    アクセスログには、非常に良い妥協案があります。バーチャルホストの
    情報をログのフォーマット文字列に加えることで、すべてのホストへの
    リクエストを同じログにログ収集して、後でログを個々のファイルに分割することが
    できます。たとえば、以下のディレクティブを見てください。
    

    
    
      LogFormat "%v %l %u %t \"%r\" %>s %b"
      comonvhost
    
      CustomLog logs/access_log comonvhost
    
    

    
    %v がリクエストを扱っているバーチャルホストの名前を
    ログ収集するために使われています。そして、split-logfile のようなプログラムを
    使ってアクセスログを後処理することで、
    バーチャルホスト毎のファイルにログを分割することができます。
    

    
    残念ながら、エラーログには同様の手法はありません。ですから、
    すべてのバーチャルホストを同じエラーログの中に混ぜるか、
    バーチャルホスト毎にエラーログを使うかを選ばなければなりません。
    
  
    top
    

    

    他のログファイル
    
    

    
    関連モジュール関連ディレクティブ
    

    
    実際に送受信したバイト数のログ
    
      

      
    mod_logio は、
         ネットワーク上で実際に送受信した数をログする
         二つのフィールド (%I と %O) を
         LogFormat 
         ディレクティブに追加します。
    
    

    
    Forensic ログ
    
      

      
    mod_log_forensic はクライアントリクエストの
         forensic ログを取ります。ログはリクエスト処理前と処理後に
         行われますので、1 リクエストに対して 2 行のログが出力されます。
         forensic ロガーはとても厳密でカスタマイズできません。
         デバッグやセキュリティ用のツールとして有効かもしれません。
    
    

    
    PID ファイル
    
      

      
    起動時に、Apache は親 httpd プロセスのプロセス ID を
      logs/httpd.pid に保存します。この
      ファイル名は PidFile ディレクティブを使って
      変更することができます。プロセス ID は管理者が親プロセスに
      シグナルを送ることでデーモンを再起動したり終了させたりするときに
      使用します。Windows では、代わりに -k コマンドオプションを
      使ってください。詳しい情報は 終了と
      再起動 のページを見てください。
    
    

    
    スクリプトログ
    
      

      
    デバッグの補助のために、ScriptLog ディレクティブは
      CGI スクリプトの入力と出力を記録するようにできます。
      これはテスト用にのみ使用して、通常のサーバでは使用しないでください。
      詳しい情報は mod_cgi の文書 にあります。
    
    

    
    リライトログ
    
      

      
    mod_rewrite の強力で
      複雑な機能を
      使っているときは、ほぼいつもデバッグを簡単にするために
      RewriteLog の使用が
      必要でしょう。このログファイルにはリライトエンジンがリクエストを
      書き換える方法の詳細な解析が出力されます。詳しさの度合は RewriteLogLevel
      で制御できます。

    Gereksinimler
    

    
    Apache httpd’yi derleyebilmek için şunlar mevcut olmalıdır:
    

    
    
      
    APR ve APR-Util
    
      
    APR ve APR-Util'in sisteminizde kurulu olduğundan emin olun. Kurulu
        değilse veya sisteminizce sağlanmış sürümlerini kullanmak
        istemiyorsanız APR ve APR-Util'in ikisini birden Apache APR'den indirin ve onları
        Apache httpd dağıtımını açtığınız dizinin altında
        /httpd_kaynakkod_kök_dizini/srclib/apr ve
        /httpd_kaynakkod_kök_dizini/srclib/apr-util dizinlerine
        açın (Dizin isimlerinin sürüm numarası içermemesine dikkat edin,
        örneğin, APR dağıtımı
        /httpd_kaynakkod_kök_dizini/srclib/apr/ altında olsun.)
        ve ./configure betiğinin --with-included-apr
        seçeneğini kullanın. Bazı platformlarda, httpd'nin, kurulu APR ve
        APR-Util kopyanıza karşın derlenmesini sağlamak için ilgili
        -dev paketlerini kurmanız gerekebilir.
    

      
    Perl-Uyumlu Düzenli İfade Kütüphanesi (PCRE)
    
      
    Bu kütüphane gereklidir, ancak artık httpd ile birlikte
        dağıtılmamaktadır. Kaynak kodunu http://www.pcre.org sitesinden indirin ve bir port veya paket
        olarak kurun. Eğer derleme sisteminiz PCRE kurulumunuz tarafından
        kurulan pcre-config betiğini bulamazsa
        --with-pcre seçeneğini kullanarak yerini belirtin. Bazı
        platformlarda, httpd'nin, kurulu PCRE kopyanıza karşın derlenmesini
        sağlamak için ilgili -dev paketlerini kurmanız
        gerekebilir.
    

      
    Disk Alanı
    
      
    Geçici olarak en azından 50 MB boş disk alanınız olduğundan emin
        olunuz. Kurulumdan sonra sunucu yaklaşık 10 MB disk alanı kaplıyor
        olacaktır. Asıl disk alanı gereksinimi seçtiğiniz yapılandırma
        seçeneklerine, üçüncü parti modüllere ve şüphesiz sitenizin veya sunucu
        üzerindeki sitelerin boyutlarına göre değişiklik
        gösterecektir.
    

      
    ANSI-C Derleyici ve Derleme Sistemi
    
      
    Bir ANSI-C derleyicinin kurulu olduğundan emin olunuz. Free Software Foundation (FSF)
        tarafından dağıtılan GNU C derleyicisini
        (GCC) kullanmanız önerilir. GCC yoksa en azından satıcınızın
        derleyicisinin ANSI uyumlu olduğundan emin olunuz. Ayrıca,
        PATH ortam değişkeninizin içerdiği yollarda
        make gibi temel derleme araçları da bulunmalıdır.
    

      
    Zamanın doğru belirlenmesi
    
      
    HTTP protokolünün elemanları sunuldukları tarih ve saate göre ifade
        edilirler. Bu bakımdan sisteminizdeki zaman ayarlama oluşumunun
        ayarlarını gözden geçirmenizin tam sırasıdır. Bu amaçla, Ağ Zaman
        Protokolüne (NTP) göre çalışan ntpdate veya
        xntpd programları kullanılır. NTP yazılımları ve halka
        açık zaman sunucuları hakkında daha ayrıntılı bilgi için NTP sitesine bakınız.
    

      
    Perl 5 [SEÇİMLİK]
    
      
    Perl ile yazılmış apxs veya
        dbmmanage gibi bazı betikleri desteklemek için
        Perl 5 yorumlayıcısı gerekir (5.003 veya daha yeni sürümleri
        yeterlidir). Eğer configure betiği sisteminizde
        Perl 5 yorumlayıcısı
        bulamazsa bu betikleri kullanamazsınız. Ancak, bu durum Apache
        HTTPd’nin derlenip kurulmasına engel değildir.

    İndirme
    

    
    Apache HTTP Sunucusunu, çeşitli yansıların da listelendiği Apache HTTP Sunucusu
      indirme sayfasından indirebilirsiniz. Unix benzeri sistemler
      kullanan Apache HTTPd kullanıcılarının kaynak paketlerinden birini
      indirip derlemeleri daha iyi olacaktır. Derleme işlemi (aşağıda
      açıklanmıştır) kolaydır ve sunucunuzu ihtiyaçlarınıza uygun olarak
      kişiselleştirmenize imkan tanır. Ayrıca, hazır derlenmiş paketler
      çoğunlukla en son kaynak sürüm kadar güncel değildirler. Eğer böyle bir
      paket indirmişseniz, kurarken paketin içinde bulunan
      INSTALL.bindist dosyasındaki talimatlara uyunuz.
    

    
    İndirme işleminin ardından Apache HTTP Sunucusunun eksiksiz ve
      değişikliğe uğramamış olduğunun doğrulanması önemlidir. Bu indirilen
      tar paketinin PGP imzasına göre sınanması ile sağlanabilir. Bunun nasıl
      yapılacağı indirme
      sayfasında anlatıldığı gibi PGP
      kullanımının anlatıldığı daha geniş bir örnek de vardır.

    Paketi açma
    

    
    Apache HTTP Sunucusu tar paketinden sıkıştırmayı kaldırdıktan sonra tar
      arşivinden dosyaları çıkarmak basit bir işlemdir:
    

    
    
      $ gzip -d httpd-NN.tar.gz
    
      $ tar xvf httpd-NN.tar
    
    

    
    Bu işlem bulunduğunuz dizinin içinde dağıtımın kaynak dosyalarını
      içeren yeni bir dizin oluşturacaktır. Sunucuyu derleme işlmine
      başlayabilmek için önce cd ile bu dizine geçmelisiniz.
    

    top
    

    

    Kaynak ağacının yapılandırılması
    

    
    Sonraki adım, Apache HTTPd kaynak ağacının platformunuza ve kişisel
      gereksinimlerinize uygun olarak yapılandırılmasıdır. Bu işlem dağıtımın
      kök dizininde bulunan configure betiği kullanılarak
      yapılır. (Apache HTTPd kaynak ağacının resmen dağıtıma girmemiş bir
      sürümünü indiren geliştiricilerin sistemlerinde autoconf ve
      libtool kurulu olması ve sonraki adıma geçmek için
      buildconf çalıştırmaları gerekir. Bu işlem resmi
      dağıtımlar için gerekli değildir.)
    

    
    Kaynak ağacını tamamen öntanımlı seçenekler kullanılarak derlemek için
      ./configure komutunu vermek yeterlidir. Öntanımlı
      seçenekleri değiştirmek için configure betiği
      çeşitli değişkenler ve komut satırı seçenekleri kabul eder.
    

    
    En önemli seçenek, Apache HTTP Sunucusunun kurulacağı yerin
      belirlenmesini, dolayısıyla Apache’nin bu konumda doğru olarak
      çalışması için yapılandırılmasını sağlayan --prefix’tir.
      Kurulacak dosyaların yerleri ile ilgili daha ayrıntılı denetim ek yapılandırma
      seçenekleri ile mümkün kılınmıştır.
    

    
    Bu noktada ayrıca, Apache HTTPd’de hangi özelliklerin bulunmasını
      istediğinizi modülleri etkin kılarak veya iptal
      ederek belirtebilirsiniz. Apache, öntanımlı olarak içerilmiş pek çok
      modülle gelir. Bunlar çalışma anında devereye sokulup çıkarılabilen paylaşımlaı nesneler (DSO'lar) olarak derlenebilir.
      Ayrıca, istediğiniz modülleri derleme sırasında
      --enable-module=static seçeneğini kullanarak
      durağan olarak derleyebilirsiniz. Ek modüller --enable-
      modül seçenekleri kullanılarak etkinleştirilir.
      Buradaki modül, önünden mod_ dizgesi
      kaldırılmış ve içindeki altçizgi imleri tire imleri ile değiştirilmiş
      modül ismidir. Temel modülleri de benzer şekilde
      --disable-modül seçenekleriyle iptal
      edebilirsiniz. configure betiği mevcut olmayan
      modüller için sizi uyarmayıp, seçeneği yok saymakla yetineceğinden, bu
      seçenekleri kullanırken dikkatli olmalısınız.
    

    
    Ek olarak, bazen kullandığınız derleyici, kütüphaneler veya başlık
      dosyalarının yerleri hakkında configure betiğine
      ilave bilgiler sağlamanız gerekir. Bu işlem
      configure betiğine ya ortam değişkenleriyle ya da
      komut satırı seçenekleriyle bilgi aktarılarak yapılır. Daha fazla bilgi
      için configure kılavuz sayfasına bakınız.
    

    
    Apache’yi derlerken ne gibi olasılıklara sahip olduğunuz hakkında bir
      izlenim edinmeniz için aşağıda tipik bir örneğe yer verilmiştir. Bu
      örnekte, Apache’nin /sw/pkg/apache önekiyle başlayan
      dizinlere kurulması, belli bir derleyici ve derleyici seçenekleriyle
      derlenmesi ve mod_ldap ve
      mod_luamodüllerinin de DSO mekanizması üzerinden
      daha sonra yüklenmek üzere derlenmesi istenmektedir:
    

    
    
      $ CC="pgcc" CFLAGS="-O2" \
    
       ./configure --prefix=/sw/pkg/apache \
    
       --enable-ldap=shared \
    
       --enable-lua=shared
    
    

    
    configure betiği başlatıldığında sisteminizde
      mevcut özelliklerin işe yararlığını sınamak ve sonradan sunucuyu
      derlemek için kullanılacak Makefile dosyalarını oluşturmak için bir kaç
      dakika çalışacaktır.
    

    
    configure seçeneklerinin tamamı ayrıtılı olarak
      configure kılavuz sayfasında açıklanmıştır.
    

    top
    

    

    Derleme
    

    
    Artık, Apache HTTPd paketini şekillendiren çeşitli parçaları derlemek
      için basitçe aşağıdaki komutu verebilirsiniz:
    

    
    $ make
    

    
    Bu komutu verdikten sonra lütfen sabırlı olunuz. Temel yapılandırmanın
      derlenmesi bir kaç dakika alsa da modüllerin derlenmesi donanımınıza ve
      seçtiğiniz modüllerin sayısına bağlı olarak daha uzun süre
      gerektirecektir.
    

    top
    

    

    Kurulum
    

    
    Şimdi sıra ÖNEK dizini altına kurulmak üzere
      yapılandırdığınız (yukarı --prefix seçeneğine bakınız)
      paketi kurmaya geldi. Basitçe şu komutu veriniz:
    


    # make install
    

    
    ÖNEK dizininde genellikle yazma izinlerinin
      sınırlı oluşu nedeniyle bu adım genellikle root yetkilerini
      gerektirir.
    

    
    Eğer sürüm yükseltiyorsanız, kurulum sırasında mevcut yapılandırma
      dosyalarının ve belgelerin üzerine yazılmayacaktır.
    

    top
    

    

    Kişiselleştirme
    

    
    Bu adımda, Apache HTTP Sunucunuzu ÖNEK/conf/
      dizini altındaki yapılandırma
      dosyalarını düzenleyerek kişiselleştirebilirsiniz.
    

    
    $ vi ÖNEK/conf/httpd.conf
    

    
    Bu kılavuz ve kullanılabilecek yapılandırma yönergelerinin kılavuzlarını
      ÖNEK/docs/manual/ altında
      bulabileceğiniz gibi en son sürümünü daima http://httpd.apache.org/docs/2.4/ adresinde
      bulabilirsiniz.
    

    top
    

    

    Deneme
    

    
    Artık Apache HTTP Sunucunuzu başlatmaya
      hazırsınız. Hemen şu komutu verin:
    

    
    $ ÖNEK/bin/apachectl -k start
    

    
    http://localhost/ üzerinden ilk belgeniz için bir istek
      yapmalısınız. Genellikle DocumentRoot olarak bilinen
      ÖNEK/htdocs/ altındaki sayfayı görürsünüz.
      Çalışmakta olan sunucuyu durdurmak için şu
      komutu verebilirsiniz:
    

    
    $ ÖNEK/bin/apachectl -k stop
    

    top
    

    

    Yükseltme
    

    
    Sürüm yükseltme işleminin ilk adımı, sitenizi etkileyen değişiklikleri
      öğrenmek için dağıtım duyurusunu ve kaynak paketindeki
      CHANGES dosyasını okumaktır. Ana sürümlerden yükseltme
      yapıyorsanız (2.0’ten 2.2’ye veya 2.2’den 2.4’e gibi), derleme anı ve
      çalışma anı yapılandırmalarındaki ana farklılıklar elle ayarlamalar
      yapmanızı gerektirecektir. Ayrıca, tüm modüllerin de modül API’sindeki
      değişikliklere uyum sağlaması için yükseltilmesi gerekecektir.
    

    
    Aynı ana sürüm içinde yükseltme yapmak (2.2.55’ten 2.2.57’ye
      yükseltmek gibi) daha kolaydır. make install işlemi,
      mevcut yapılandırma ve günlük dosyalarınızın ve belgelerin üzerine
      yazmayacaktır. Ek olarak, geliştiriciler alt sürüm değişikliklerinde
      configure seçenekleri, çalışma anı yapılandırması
      veya modül API’sinde uyumsuz değişiklikler yapmamaya özen
      göstereceklerdir. Çoğu durumda, aynı configure komut
      satırını, aynı yapılandırma dosyasını kullanabileceksiniz ve tüm
      modülleriniz de çalışmaya devam edebilecektir.
    

    
    Aynı ana sürüm içinde yükseltme işlemine, eski kaynak ağacının kök
      dizininde veya kurulu sunucunuzun build dizininde
      bulacağınız config.nice dosyasını yeni kaynak ağacının kök
      dizinine kopyalamak suretiyle başlayabilirsiniz. Bu dosya evvelce
      kaynak ağacını yapılandırmakta kullandığınız
      configure komut satırını içerir.
      config.nice dosyasında yapmak istediğiniz değişiklikler
      varsa yaptıktan sonra şu komutları veriniz:
    

    
    
    $ ./config.nice
    
    $ make
    
    $ make install
    
    $ ÖNEK/bin/apachectl -k graceful-stop
    
    $ ÖNEK/bin/apachectl -k start
    
    
    

    
    Her yeni sürümü hizmete sokmadan önce daima çalışma
      ortamınızda denemeniz gerekir. Örneğin, yükseltme işlemini
      sonuçlandırmadan önce eski sürümün çalışmasını durdurmadan yenisini
      farklı bir --prefix ile kurabilir ve farklı bir port ile
      (Listen yönergesini
      ayarlamak suretiyle) çalıştırabilirsiniz.
    

    
    Özgün configure seçeneklerinizi değiştirmek veya
      yeni seçenekler eklemek isterseniz bunları config.nice
      betiğine komut satırı argümanları olarak belirtebilirsiniz:
    

    
    
    $ ./config.nice --prefix=/home/dnm/apache --with-port=90
    
    

    top
    

    

    Üçüncü parti paketler
    

    
    Üçüncü partilerin çoğunun, Apache HTTP Sunucusunun belli bir platforma
      kurulumu için paketlenmiş kendi dağıtımları vardır. Çeşitli Linux
      dağıtımları, üçüncü parti Windows paketleri, Mac OS X, Solaris ve daha
      pek çokları bunlar arasında sayılabilir.r
    

    
    Yazılım lisansımız bu çeşit yeniden dağıtımlara izin verdiği gibi
      bunları cesaretlendirir de. Ancak, sunucunun kurulum ve yapılandırmasının
      belgelerimizde belittiğimizden farklı olması gibi bir durum ortaya
      çıkabilir. Ne yazık ki, bu durum yakın zamanda değişecekmiş gibi
      görünmüyor.
    

    
    Bu üçüncü parti
      dağıtımlarla ilgili bir açıklamaya HTTP
      Sunucu wikisinde yer verilmiş olup bunların şu anki durumunu
      yansıtmaktadır. Ancak, yine de, dağıtımınızın belli platformlarla ilgili
      paket yönetimi ve kurulum işlemleri hakkında bilgi sahibi olmanız
      gerekmektir.

    In order to assist folks upgrading, we maintain a document
  describing information critical to existing Apache HTTP Server users. These
  are intended to be brief notes, and you should be able to find
  more information in either the New Features document, or in
  the src/CHANGES file.  Application and module developers
  can find a summary of API changes in the API updates overview.
    

  
    This document describes changes in server behavior that might
  require you to change your configuration or how you use the server
  in order to continue using 2.4 as you are currently using 2.2.
  To take advantage of new features in 2.4, see the New Features
  document.
    

  
    This document describes only the changes from 2.2 to 2.4.  If you
  are upgrading from version 2.0, you should also consult the 2.0 to 2.2
  upgrading document.

    Compile-Time Configuration Changes
    
    

    
    The compilation process is very similar to the one used in
    version 2.2.  Your old configure command line (as
    found in build/config.nice in the installed server
    directory) can be used in most cases.  There are some changes in
    the default settings.  Some details of changes:
    

    
      
      
    • These modules have been removed: mod_authn_default,
      mod_authz_default, mod_mem_cache.  If you were using
      mod_mem_cache in 2.2, look at mod_cache_disk in
      2.4.
      • 

      
    • All load balancing implementations have been moved to
      individual, self-contained mod_proxy submodules, e.g.
      mod_lbmethod_bybusyness.  You might need
      to build and load any of these that your configuration
      uses.
      • 

      
    • Platform support has been removed for BeOS, TPF, and
      even older platforms such as A/UX, Next, and Tandem.  These were
      believed to be broken anyway.
      • 

      
    • configure: dynamic modules (DSO) are built by default
      • 

      
    • configure: By default, only a basic set of modules is loaded. The
      other LoadModule directives are commented
      out in the configuration file.
      • 

      
    • configure: the "most" module set gets built by default
      • 

      
    • configure: the "reallyall" module set adds developer modules
      to the "all" set
      •

    Run-Time Configuration Changes
    
    
    
    There have been significant changes in authorization configuration,
    and other minor configuration changes, that could require changes to your 2.2
    configuration files before using them for 2.4.
    

    
    Authorization
    
      

      
    Any configuration file that uses authorization will likely
      need changes.
    

    
    You should review the Authentication,
    Authorization and Access Control Howto, especially the section
    Beyond just authorization
    which explains the new mechanisms for controlling the order in
    which the authorization directives are applied.
    

    
    Directives that control how authorization modules respond when they don't match
    the authenticated user have been removed: This includes 
    AuthzLDAPAuthoritative, AuthzDBDAuthoritative, AuthzDBMAuthoritative, 
    AuthzGroupFileAuthoritative, AuthzUserAuthoritative,
    and AuthzOwnerAuthoritative.   These directives have been replaced by the
    more expressive RequireAny, 
    RequireNone, and
    RequireAll.
    

    
    If you use mod_authz_dbm, you must port your 
    configuration to use Require dbm-group ... in place
    of Require group ....
    

    
    Access control
    
      

      
    In 2.2, access control based on client hostname, IP address,
      and other characteristics of client requests was done using the
      directives Order, Allow, Deny, and Satisfy.
    

      
    In 2.4, such access control is done in the same way as other
      authorization checks, using the new module
      mod_authz_host.  The old access control idioms
      should be replaced by the new authentication mechanisms,
      although for compatibility with old configurations, the new
      module mod_access_compat is provided.
    

      
    Mixing old and new directives
    
      
    Mixing old directives like Order, Allow or Deny with new ones like
      Require is technically possible 
      but discouraged. mod_access_compat was created to support 
      configurations containing only old directives to facilitate the 2.4 upgrade. 
      Please check the examples below to get a better idea about issues that might arise.
      
    
      
    

      
    Here are some examples of old and new ways to do the same
      access control.
    

      
    In this example, there is no authentication and all requests are denied.
    
      
    2.2 configuration:
    Order deny,allow
Deny from all
    

    
      
    2.4 configuration:
    Require all denied
    

    

      
    In this example, there is no authentication and all requests are allowed.
    
      
    2.2 configuration:
    Order allow,deny
Allow from all
    

    
      
    2.4 configuration:
    Require all granted
    

    

      
    In the following example, there is no authentication and all hosts in the example.org domain
      are allowed access; all other hosts are denied access.
    

      
    2.2 configuration:
    Order Deny,Allow
Deny from all
Allow from example.org
    

    
      
    2.4 configuration:
    Require host example.org
    

    

      
    In the following example, mixing old and new directives leads to 
      unexpected results.
    
 
      
    Mixing old and new directives: NOT WORKING AS EXPECTED
    DocumentRoot "/var/www/html"

<Directory "/">
    AllowOverride None
    Order deny,allow
    Deny from all
</Directory>

<Location "/server-status">
    SetHandler server-status
    Require local
</Location>

access.log - GET /server-status 403 127.0.0.1
error.log - AH01797: client denied by server configuration: /var/www/html/server-status
    

    
      
    Why httpd denies access to servers-status even if the configuration seems to allow it?
        Because mod_access_compat directives take precedence
        over the mod_authz_host one in this configuration 
        merge scenario.
    

      
    This example conversely works as expected:
    

      
    Mixing old and new directives: WORKING AS EXPECTED
    DocumentRoot "/var/www/html"

<Directory "/">
    AllowOverride None
    Require all denied
</Directory>

<Location "/server-status">
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow From 127.0.0.1
</Location>

access.log - GET /server-status 200 127.0.0.1
    

     
      
    So even if mixing configuration is still
        possible, please try to avoid it when upgrading: either keep old directives and then migrate
        to the new ones on a later stage or just migrate everything in bulk.  
      
    
    

     
    In many configurations with authentication, where the value of the
     Satisfy was the default of ALL, snippets
     that simply disabled host-based access control are omitted:
    

      
    2.2 configuration:
    # 2.2 config that disables host-based access control and uses only authentication
Order Deny,Allow
Allow from all
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    
      
    2.4 configuration:
    # No replacement of disabling host-based access control needed
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    

     
    In configurations where both authentication and access control were meaningfully combined, the 
        access control directives should be migrated. This example allows requests meeting both criteria:
    
      
    2.2 configuration:
    Order allow,deny
Deny from all
# Satisfy ALL is the default
Satisfy ALL
Allow from 127.0.0.1
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    
      
    2.4 configuration:
    AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
<RequireAll>
  Require valid-user
  Require ip 127.0.0.1
</RequireAll>
    

    

     
    In configurations where both authentication and access control were meaningfully combined, the 
        access control directives should be migrated. This example allows requests meeting either criteria:
    
      
    2.2 configuration:
    Order allow,deny
Deny from all
Satisfy any
Allow from 127.0.0.1
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    
      
    2.4 configuration:
    AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
# Implicitly <RequireAny>
Require valid-user
Require ip 127.0.0.1
    

    

    

    
    Other configuration changes
    
      

      
    Some other small adjustments may be necessary for particular
      configurations as discussed below.
    

      
      
        
    • MaxRequestsPerChild has been renamed to
        MaxConnectionsPerChild,
        describes more accurately what it does. The old name is still
        supported.
      • 

        
    • MaxClients has been renamed to
        MaxRequestWorkers,
        which describes more accurately what it does. For async MPMs, like
        event, the maximum number of clients is not
        equivalent than the number of worker threads. The old name is still
        supported.
      • 

        
    • The DefaultType
        directive no longer has any effect, other than to emit a
        warning if it's used with any value other than
        none.  You need to use other configuration
        settings to replace it in 2.4.
        
      • 

        
    • AllowOverride now
        defaults to None.
      • 

        
    • EnableSendfile now
        defaults to Off.
      • 

        
    • FileETag now
        defaults to "MTime Size" (without INode).
      • 

        
    • mod_dav_fs: The format of the DavLockDB file has changed for
        systems with inodes.  The old DavLockDB file must be deleted on
        upgrade.
        
      • 

        
    • KeepAlive only
        accepts values of On or Off.
        Previously, any value other than "Off" or "0" was treated as
        "On".
      • 

        
    • Directives AcceptMutex, LockFile, RewriteLock, SSLMutex,
        SSLStaplingMutex, and WatchdogMutexPath have been replaced
        with a single Mutex
        directive.  You will need to evaluate any use of these removed
        directives in your 2.2 configuration to determine if they can
        just be deleted or will need to be replaced using Mutex.
      • 

        
    • mod_cache: CacheIgnoreURLSessionIdentifiers
        now does an exact match against the query string instead of a
        partial match.  If your configuration was using partial
        strings, e.g. using sessionid to match
        /someapplication/image.gif;jsessionid=123456789,
        then you will need to change to the full string
        jsessionid.
        
      • 

        
    • mod_cache: The second parameter to 
        CacheEnable only
        matches forward proxy content if it begins with the correct
        protocol. In 2.2 and earlier, a parameter of '/' matched all
        content.
      • 

        
    • mod_ldap: LDAPTrustedClientCert is now
        consistently a per-directory setting only.  If you use this
        directive, review your configuration to make sure it is
        present in all the necessary directory contexts.
      • 

        
    • mod_filter: FilterProvider syntax has changed and
        now uses a boolean expression to determine if a filter is applied.
        
      • 

        
    • mod_include:
            
        
            
      • The #if expr element now uses the new expression parser. The old syntax can be
            restored with the new directive SSILegacyExprParser.
            
        • 
            
      • An SSI* config directive in directory scope no longer causes
            all other per-directory SSI* directives to be reset to their
            default values.
        • 
            
      
        
      • 

        
    • mod_charset_lite: The DebugLevel
        option has been removed in favour of per-module LogLevel configuration.
        
      • 

        
    • mod_ext_filter: The DebugLevel
        option has been removed in favour of per-module LogLevel configuration.
        
      • 

        
    • mod_proxy_scgi: The default setting for
        PATH_INFO has changed from httpd 2.2, and
        some web applications will no longer operate properly with
        the new PATH_INFO setting.  The previous setting
        can be restored by configuring the proxy-scgi-pathinfo
        variable.
      • 

        
    • mod_ssl: CRL based revocation checking
        now needs to be explicitly configured through SSLCARevocationCheck.
        
      • 

        
    • mod_substitute: The maximum line length is now
        limited to 1MB.
        
      • 

        
    • mod_reqtimeout: If the module is loaded, it
        will now set some default timeouts.
      • 

        
    • mod_dumpio: DumpIOLogLevel
        is no longer supported.  Data is always logged at LogLevel trace7.
      • 

        
    • On Unix platforms, piped logging commands configured using
        either ErrorLog or
        CustomLog were invoked using
        /bin/sh -c in 2.2 and earlier.  In 2.4 and later,
        piped logging commands are executed directly.  To restore the
        old behaviour, see the piped logging
        documentation.
      • 

      
    
    
  
    top
    

    

    Misc Changes
    
    

    
      
      
    • mod_autoindex: will now extract titles and
      display descriptions for .xhtml files, which were previously
      ignored.
      • 

      
    • mod_ssl: The default format of the *_DN
      variables has changed. The old format can still be used with the new
      LegacyDNStringFormat argument to SSLOptions. The SSLv2 protocol is
      no longer supported. SSLProxyCheckPeerCN
	   and SSLProxyCheckPeerExpire
	   now default to On, causing proxy requests to HTTPS hosts
	  with bad or outdated certificates to fail with a 502 status code (Bad 
	  gateway)
      • 

      
    • htpasswd now uses MD5 hash by default on
      all platforms.
      • 

      
    • The NameVirtualHost
      directive no longer has any effect, other than to emit a
      warning.  Any address/port combination appearing in multiple
      virtual hosts is implicitly treated as a name-based virtual host.
      
      • 

      
    • mod_deflate will now skip compression if it knows
      that the size overhead added by the compression is larger than the data
      to be compressed.
      
      • 

      
    • Multi-language error documents from 2.2.x may not work unless
      they are adjusted to the new syntax of mod_include's
      #if expr= element or the directive
      SSILegacyExprParser is
      enabled for the directory containing the error documents.
      
      • 

      
    • The functionality provided by mod_authn_alias
      in previous versions (i.e., the AuthnProviderAlias directive)
      has been moved into mod_authn_core.  
      
      • 

      
    • The RewriteLog and RewriteLogLevel directives have been removed.
      This functionality is now provided by configuring the appropriate
      level of logging for the mod_rewrite module using
      the LogLevel directive.
      See also the mod_rewrite logging
      section.

    Third Party Modules
    
    
    
    All modules must be recompiled for 2.4 before being loaded.
    

    
    Many third-party modules designed for version 2.2 will
    otherwise work unchanged with the Apache HTTP Server version 2.4.
    Some will require changes; see the API
    update overview.
    
  
    top
    

    

    Common problems when upgrading
    
    
    
    • Startup errors:
    
        
      
      • Invalid command 'User', perhaps misspelled or defined by a module not included in the server configuration - load module mod_unixd
        • 
      
      • Invalid command 'Require', perhaps misspelled or defined by a module not included in the server configuration, or
Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration
 - load module mod_access_compat, or update configuration to 2.4 authorization directives.
        • 
      
      • Ignoring deprecated use of DefaultType in line NN of /path/to/httpd.conf - remove DefaultType
      and replace with other configuration settings.
        • 
      
      • Invalid command 'AddOutputFilterByType', perhaps misspelled 
      or defined by a module not included in the server configuration
       - AddOutputFilterByType 
      has moved from the core to mod_filter, which must be loaded.
        • 
    
      • 
    
    • Errors serving requests:
    
        
      
      • configuration error:  couldn't check user: /path -
      load module mod_authn_core.
        • 
      
      • .htaccess files aren't being processed - Check for an
      appropriate AllowOverride directive;
      the default changed to None in 2.4.
        •

    Bu belgede Apache Eylemcilerinin kullanımı açıklanmıştır.

    Eylemci Nedir?
    
    
    
    İlgili Modüllerİlgili Yönergeler
    


    
    Bir eylemci bir dosya çağrıldığında uygulanacak eylemin Apache
      dahilindeki gösterimidir. Genellikle dosyaların kendi türüne bağlı
      olarak örtük eylemcileri vardır. Normalde tüm dosyalar basitçe sunucu
      tarafından sunulurlar, fakat bazı dosya türleri normalden farklı şekilde
      ele alınırlar.
    

    
    Eylemciler, dosya türünden bağımsız olarak dosyanın bulunduğu yere veya
      dosya ismi uzantısına göre de yapılandırılabilirler. Gerek, zarif bir
      çözüm oluşuyla gerekse, hem dosya türünü hem de bir dosya ile ilişkili
      bir eylemciyi mümkün kılması sebebiyle bunun getirisi daha yüksektir.
      (Ayrıca, çok uzantılı
      dosyalara da bakınız.)
    

    
    Eylemciler sunucu içinde derlenebileceği gibi bir modül olarak ya da
      Action yönergesi ile de
      sunucuya dahil edilebilirler. Standart dağıtımda bulunan yerleşik
      eylemciler şunlardır:
    

    
      
      
    • default-handler: Dosyayı, öntanımlı olarak durağan
        içeriği işlemekte kullanılan default_handler() işlevini
        kullanarak gönderir. (core)
      • 

      
    • send-as-is: Dosyayı HTTP başlıklarıyla olduğu gibi
        gönderir. (mod_asis)
      • 

      
    • cgi-script: Dosyayı bir CGI betiği olarak ele alır.
        (mod_cgi)
      • 

      
    • imap-file: Dosyayı bir resim eşleme kuralları
        dosyası olarak çözümler. (mod_imagemap)
      • 

      
    • server-info: Sunucunun yapılandırma bilgisini
        döndürür. (mod_info)
      • 

      
    • server-status: Sunucunun durum raporunu döndürür.
        (mod_status)
      • 

      
    • type-map: Dosyayı içerik uzlaşımı için bir tür
        eşlem dosyası olarak çözümler. (mod_negotiation)
      • 
    
    
  
    top
    

    

    Örnekler
    
    

    
    Bir CGI betiği kullanarak durağan içeriğin değiştirilmesi
    
      

      
    Aşağıdaki yönergeler sayesinde, html uzantılı dosyalar
        için yapılan istekler footer.pl CGI betiğininin
        çalıştırılmasına sebep olacaktır.
    

      
    Action add-footer /cgi-bin/footer.pl
AddHandler add-footer .html
    


      
    Bu yapılandırmayla, istenen belgenin özgün haliyle mi (yeri
        PATH_TRANSLATED ortam değişkenindedir) yoksa istenen
        değişiklikler veya eklemeler yapıldıktan sonra mı gönderileceğinden
        CGI betiği sorumlu olacaktır.
    

    
    
    HTTP başlıklı dosyalar
    
      

      
    Aşağıdaki yönergeler kendi HTTP başlıklarını içeren dosyalar için
        kullanılan send-as-is eylemcisini etkinleştirmek amacıyla
        kullanılmıştır. /siteler/htdocs/asis/ dizinindeki tüm
        dosyalar dosya ismi uzantılarına bakılmaksızın send-as-is
        eylemcisi tarafından işleme sokulacaktır.
    

      
    <Directory "/web/htdocs/asis">
    SetHandler send-as-is
</Directory>
    


    
  
    top
    

    

    Yazılım Geliştirenler İçin
    
    

    
    Eylemci özellikleri gerçeklenirken kullanılmak üzere Apache API’ye bir ekleme yapılmıştır.
      Özellikle de, request_rec yapısına yeni bir kayıt
      eklenmiştir:
    

    
    char *handler
    


    
    Modülünüzün bir eylemciyi devreye sokmasını isterseniz, tek yapacağınız
      isteğin invoke_handler aşamasının hemen öncesinde
      r->handler alanına eylemcinin ismini atamak olacaktır.
      Eylemciler daha önce de bahsedildiği gibi bir içerik türü yerine bir
      eylemci ismi kullanılarak gerçeklenirler. Çok gerekli olmamakla
      birlikte, eylemciler için kullanılan adlandırma uzlaşımları gereğince,
      ismi oluşturan sözcükler, ortam türü isim alanını ihlal etmemek amacıyla
      bölü imleri ile değil tire imleri ile ayrılırlar.

    Cette page pourrait se résumer ainsi : configurez le
    serveur HTTP Apache de façon
    à ce qu'il n'ait pas besoin de résolution DNS pour interpréter les
    fichiers de configuration. Si httpd doit effectuer des résolutions
    DNS pour interpréter les fichiers de configuration, votre serveur
    pourra présenter des problèmes de fiabilité (en d'autres termes,
    il est possible qu'il refuse de démarrer), ou d'attaques par déni ou
    usurpation de service (y compris l'attribution de requêtes à un
    serveur virtuel autre que le serveur virtuel voulu).
    
  
    


    top
    

    

    Un exemple simple
    
    

    
    # Ceci est un exemple de mauvaise configuration ; ne l'utilisez pas comme base
# de configuration
<VirtualHost www.example.dom>
  ServerAdmin webgirl@example.dom
  DocumentRoot "/www/example"
</VirtualHost>
    


    
    Pour fonctionner correctement, le serveur a absolument besoin de deux
    informations à propos de chaque serveur virtuel : le nom du serveur
    défini par la directive ServerName, et au moins une adresse IP à
    laquelle le serveur va se rattacher et répondre. L'exemple ci-dessus
    ne comporte pas d'adresse IP, si bien que httpd devra utiliser le
    DNS pour trouver l'adresse IP de www.example.dom. Si pour
    une raison quelconque, le DNS n'est pas disponible au moment où
    votre serveur interprète son fichier de configuration, ce serveur
    virtuel ne sera pas pris en compte dans la
    configuration. Il sera incapable de
    répondre à toute requête pour ce serveur virtuel.
    

    
    Supposons que l'adresse de www.example.dom soit
    192.0.2.1, et examinons cet extrait de configuration :
    

    
    # Ceci est un exemple de mauvaise configuration ; ne l'utilisez pas comme base
# de configuration
<VirtualHost 192.0.2.1>
  ServerAdmin webgirl@example.dom
  DocumentRoot "/www/example"
</VirtualHost>
    


    
    Cette fois, httpd doit effectuer une recherche DNS inverse pour
    trouver le nom ServerName de ce serveur virtuel. Si
    cette recherche inverse échoue, le serveur virtuel sera
    partiellement désactivé. Si le serveur
    virtuel est à base de nom, il sera en fait totalement désactivé,
    mais s'il est à base d'adresse IP, il fonctionnera probablement.
    Cependant, httpd échouera s'il doit générer une URL complète pour
    le serveur qui inclut ce nom de serveur (comme dans le cas d'une
    redirection).
    

    
    Voici un extrait de configuration qui permet d'éviter ces deux
    types de problèmes :
    

    
    <VirtualHost 192.0.2.1>
  ServerName www.example.dom
  ServerAdmin webgirl@example.dom
  DocumentRoot "/www/example"
</VirtualHost>
    

  
    top
    

    

    Déni de service
    
    

    
    Considérons cet extrait de configuration :
    

    
    <VirtualHost www.example1.dom>
  ServerAdmin webgirl@example1.dom
  DocumentRoot "/www/example1"
</VirtualHost>
<VirtualHost www.example2.dom>
  ServerAdmin webguy@example2.dom
  DocumentRoot "/www/example2"
</VirtualHost>
    


    
    Supposons que vous ayez assigné 192.0.2.1 à
    www.example1.dom et 192.0.2.2 à www.example2.dom. En
    outre, supposons que example1.dom gère son propre DNS. Avec
    cette configuration, example1.dom sera en mesure de
    détourner tout trafic destiné à example2.dom. Pour y
    parvenir, tout ce qu'ils ont à faire consiste à
    assigner 192.0.2.2 à
    www.example1.dom. Comme ils gèrent leur propre DNS, vous ne
    pouvez pas les empêcher de faire pointer l'enregistrement
    www.example1.dom vers l'adresse qu'ils veulent.
    

    
    Les requêtes à destination de 192.0.2.2 (y compris toutes celles
    où l'utilisateur à tapé une URL de la forme
    http://www.example2.dom/quelquepart), seront toutes servies
    par le serveur virtuel example1.dom. Une meilleur
    compréhension de la raison pour laquelle ceci peut se produire
    nécessite une discussion plus approfondie à propos de la manière
    dont httpd associe les requêtes entrantes aux différents serveurs
    virtuels qui vont les servir. Un document de base décrivant ceci est disponible.
    
  
    top
    

    

    L'adresse du "serveur principal"
    
    

    
    Le support des
    serveurs virtuels à base de nom oblige httpd à
    connaître la/les adresse(s) IP de l'hôte sur
    lequel httpd s'exécute. Pour obtenir cette
    adresse, soit il utilise la directive ServerName globale (si elle est présente),
    soit il fait appel à la fonction C gethostname (qui
    doit renvoyer le même nom que la commande shell "hostname"). Il
    effectue ensuite une recherche DNS sur cette adresse. Pour le
    moment, il n'existe aucun moyen d'éviter cette recherche DNS.
    

    
    Si vous craignez que cette recherche DNS échoue parce que votre
    serveur DNS est arrêté, vous pouvez insérer le nom d'hôte dans le
    fichier /etc/hosts (où il est probablement déjà
    enregistré afin que la machine démarre correctement). Assurez-vous
    ensuite que la machine est configurée pour utiliser
    /etc/hosts dans le cas où la recherche DNS échoue.
    Suivant le système d'exploitation que vous utilisez, vous y
    parviendrez en éditant /etc/resolv.conf, ou
    /etc/nsswitch.conf.
    

    
    Si votre serveur n'a aucune autre raison d'effectuer des
    recherches DNS, vous pouvez définir la variable d'environnement
    HOSTRESORDER à "local", et vous serez alors en mesure
    d'exécuter httpd. Tout dépend du système d'exploitation et des
    bibliothèques de résolution de noms que vous utilisez. Elle affecte
    aussi les programmes CGI, à moins que vous n'utilisiez
    mod_env pour contrôler l'environnement. Il est
    conseillé de consulter les pages de manuel ou les FAQs de votre
    système d'exploitation.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    
    Apache HTTP サーバは環境変数と呼ばれる、名前のついた
    変数に情報を記憶する仕組みを提供しています。この情報はログ収集や
    アクセス制御などのいろいろな操作を制御するために使うことができます。
    これらの変数は CGI スクリプトなどの外部プログラムと通信するためにも
    使われます。この文書はそれらの変数の操作方法と使用方法をいくつか
    紹介します。
    

    
    これらの変数は環境変数と呼ばれていますが、オペレーティング
    システムによって制御されている環境変数と同じではありません。
    実際は、これらの変数は Apache の内部構造の中に記憶され、操作されています。
    それらは、CGI や SSI スクリプトに渡されたときだけ、実際の
    オペレーティングシステムの環境変数になります。サーバ自身が
    実行されているオペレーティングシステムの環境を操作したい場合は、
    オペレーティングシステムのシェルが提供している標準の環境変数の
    操作方法を使わなければなりません。

    環境変数の設定
    
    
    
    関連モジュール関連ディレクティブ
    

    
    基本的な環境の操作
    
        

        
    Apache において環境変数を設定する一番基本的な方法は、
        無条件に環境変数を設定する SetEnv ディレクティブを使用することです。
	PassEnv 
        ディレクティブにより、Apache が起動されたシェルの
        環境変数を渡すこともできます。
    

    
    
    リクエスト毎に条件に基づいて設定する
    
        

        
    より柔軟性を高めるために、mod_setenvif
        で提供されているディレクティブを使用することで、リクエストの
        特性に基づいて環境変数を設定することができます。例えば、特定のブラウザ
        (User-Agent) のリクエストや特定の Referer [意図的な綴りです]
        (訳注: 正しい綴りは referrer ですが、HTTP の仕様では Referer
        となっています)ヘッダが見つかったときのみ変数を設定することができます。
        mod_rewrite の RewriteRule
	ディレクティブにおいて環境変数を設定する [E=...]
	オプションを使用することで、
        より柔軟な設定を行なうことができます。
    

    
    
    一意な識別子
    
        

        
    mod_unique_id は、非常に限られた条件の下で
        「すべて」のリクエストについて、一意であることが保証されている値を環境変数
        UNIQUE_ID に設定します。
    

    
    
    標準 CGI 変数
    
        

        
    Apache の設定ファイルで設定された環境変数とシェルから渡される
        環境変数に加えて、CGI スクリプトと SSI ページには CGI の仕様で要求されている、
        リクエストのメタ情報を持った環境変数の組が提供されます。
    

    
    
    いくつかの注意
    
        

        
      
          
    • 環境を操作するディレクティブを使って標準 CGI
          変数を上書きしたり変更したりすることはできません。
      • 

          
    • CGI スクリプトを起動するために suexec
          が使用されている場合、CGI スクリプトが起動するために、環境変数は安全な環境変数の組に整理されます。
          この安全な環境変数の集合は、コンパイル時に suexec.c
          で定義されます。
      • 

          
    • 移植性のために、環境変数の名前はアルファベット、
          数字とアンダースコア (訳注: '_') だけから成ります。
          さらに、最初の文字は数字であってはいけません。
          この制限に合わない文字は CGI スクリプトと SSI
          ページに渡されるときにアンダースコアに置換されます。
      • 
          
          
    • SetEnv はリクエスト処理の
          段階の中でも遅くに実行されます。つまり
          SetEnvIf や
          RewriteCond
          などからは、変数がそこで設定されていることがわかりません。
      •

    環境変数の使用
    
    

    
    関連モジュール関連ディレクティブ
    

    
    CGI スクリプト
    
        

        
    環境変数の主な利用法の一つは、CGI スクリプトに情報を伝えることです。
        上で説明されているように、CGI スクリプトに渡される環境変数は Apache
        の設定により設定される変数に加えて、リクエストの標準のメタ情報を含んでいます。
        詳細は CGI チュートリアル
	を参照してください。
    

    
    
    SSI ページ
    
        

        
    mod_include の INCLUDES フィルタで処理される
        server-parsed (SSI) ドキュメントでは、echo
        要素を使用すると環境変数が出力されます。
        また、ページのある部分がリクエストの性質に応じて変更されるように、
        環境変数をフロー制御要素で使うことができます。詳細は
        SSI チュートリアル を参照してください。
    

    
    
    アクセス制御
    
        

        
    allow from env= ディレクティブと deny from env=
        ディレクティブを使用して、サーバへのアクセスを環境変数の値で制御することができます。
        SetEnvIf
	ディレクティブと組み合わせることで、クライアントの特性に基づいて
        サーバへのアクセス制御を柔軟に行なうことができるようになります。
        たとえば、これらのディレクティブを使用して、特定のブラウザ (User-Agent)
        からのアクセスを拒否することができます。
    

    
    
    条件付きログ記録
    
        

        
    LogFormat
        ディレクティブのオプション %e
        を使用することで、環境変数をアクセスログに記録することができます。さらに、
        CustomLog
	ディレクティブの条件分岐式を使用することで、
        環境変数の値によってリクエストをログに記録するかどうかを決めることができます。
        SetEnvIf
	ディレクティブと組み合わせることで、
        どのリクエストをログに記録するかを柔軟に制御することが可能になります。たとえば、
        gif で終わるファイル名へのリクエストはログに記録しない、
        違うサブネットのクライアントからのリクエストだけをログに記録する、
	という選択が可能です。
    

    
    
    条件付き応答ヘッダ
    
        

        
    Header
	ディレクティブは環境変数の存在や不在によってクライアントへの応答に特定の
	HTTP ヘッダを付けるかどうかを決めることができます。
	これにより、たとえば、クライアントからのリクエスト
        にあるヘッダがある場合にのみ特定の応答ヘッダを送る、というようなことが
        できます。
    

    

    
    外部フィルタの適用
    
        

        
    ExtFilterDefine
        ディレクティブを使用して
        mod_ext_filter で設定される外部フィルタは、
	disableenv= と enableenv=
	オプションを使って、環境変数による条件付き適用ができます。
    
    

    
    URL の書き換え
    
        

        
    RewriteCond
	ディレクティブで評価文字列として
        %{ENV:...} 式を指定することで、mod_rewrite
        の書き換えエンジンが環境変数に基いて条件分岐を行なうことができます。
        mod_rewrite が使用可能な変数で ENV: が前についていない変数は、
        実際は環境変数ではないということに注意してください。
        それらは他のモジュールからは使用できない mod_rewrite 用の特別な変数です。
        
    
    
  
    top
    

    

    特別な目的の環境変数
    
    

        
    互換性の問題を解決するために、特定のクライアントと通信しているときは
        Apache の動作を変更できる機構が導入されました。できるだけ柔軟にするために、
        これらの機構は環境変数を定義することで呼び出されます。普通は、
        BrowserMatch
        ディレクティブを使いますが、たとえば SetEnv ディレクティブや PassEnv ディレクティブも使用することができます。
    

    
    downgrade-1.0
    
        

        
    これを指定することで、リクエストが HTTP/1.0
        より新しいプロトコルの場合でも、HTTP/1.0 として扱われます。
    

    
    
    force-gzip
    
        
          
    DEFLATE フィルタが使用するように設定されているときに、
          この環境変数はブラウザの accept-encoding の設定を無視して常に
          圧縮された出力を送るようにします。
    
    
    
    force-no-vary
    
        

        
    応答ヘッダがクライアントに送られる前に Vary
        フィールドを取り除きます。
        クライアントの中にはこのフィールドを正しく解釈しないものがあります。
        この変数を設定することでその問題を回避することができます。
        この変数を設定すると、force-response-1.0
        が設定されたことになります。
    

    
    
    force-response-1.0
    
        

        
    これが設定されていると、HTTP/1.0 リクエストを発行するクライアントに対しては
	常に HTTP/1.0 で応答するようになります。この機能は、
        元々は AOL のプロキシの問題のために実装されました。HTTP/1.0 クライアントの中には、
        HTTP/1.1 の応答を返されると正しく動作しないものがあるかもしれません。
        この機能を使用することで、そのようなクライアントとの間の互換性問題を解決できます。
    
    

    
    gzip-only-text/html
    
        

	
    これが 1 に設定されると、この変数は text/html
	以外のコンテントタイプに対する、mod_deflate
	提供の DEFLATE 出力フィルタを無効にします。
        また、静的に、既に圧縮されたファイルを使用したい場合、
        (gzip だけでなく、"identity" と異なる全てのエンコードに対して)
        mod_negotiation も変数を評価します。
    
    

    
    no-gzip
    
        
    セットされると、mod_deflate の
	DEFLATE フィルタがオフになります。
        そして mod_negotiation
        はエンコードされたリソースを送らないようにします。
    
    

    
    nokeepalive
    
        

        
    これが設定されている場合は、KeepAlive を使用しないようにします。
    

    
    prefer-language
    

        
    mod_negotiation の挙動に影響を与えます。
        (en, ja, x-klingonといった)
        言語タグが格納されていれば、その言語の variant を送信しようとします。
        そのような variant がない場合は、
        通常のネゴシエーション処理が
        適用されます。
    

    

    
    
    redirect-carefully
    
        

        
    これはクライアントへのリダイレクトの送信をサーバがより注意深く
        行なうようにします。
        これは通常、リダイレクトに際してクライアントに
        問題があることが分かっている場合に使われます。この機能は元々は
        マイクロソフトのウェブフォルダのソフトが DAV
        メソッドによるディレクトリのリソースへのリダイレクトの扱いに
        問題がり、それを回避するために実装されました。
    

    

   
    suppress-error-charset
    
       

    
    Apache 2.2 以降で利用可能
    

    
    クライアントのリクエストに対する応答としてリダイレクトを送信する際、
    レスポンスにはリダイレクトが自動的に行なえない (行なわれない)
    場合に表示するテキストが含まれます。
    通常、このテキストに合致したキャラクタセット、ISO-8859-1
    でラベル付けをします。
    
    
    しかし、リダイレクト先が別の文字セットを使っている場合、
    ある問題のあるブラウザのバージョンでは、
    リダイレクト先の実際の文字セットの代わりに、
    リダイレクト元の文字セットを使ってしまうことがあります。
    その結果、例えば変な描画が行なわれたりして、読めなくなったりします。
    
    
    この環境変数を設定することで、リダイレクションテキストに対する
    キャラクタセットの指定を除去しますので、それら問題のあるブラウザでも
    リダイレクト先の文字セットを正しく使うようにできます。
    

    
    
      
    セキュリティ
     

      
    文字セットを指定せずにエラーページを送信すると、
      クロスサイトスクリプティング (訳注: XSS)
      攻撃の危険性がでてきます。
      HTTP/1.1 仕様に準拠していなくて、コンテンツの中身から文字セットを
      "推測" しようとするブラウザ (MSIE) が実際にあるからです。
      そのようなブラウザは UTF-7 文字セットを使って簡単に騙すことができます。
      クロスサイトスクリプティング攻撃を防ぐために実装されている
      通常のエスケープ機構が、入力データ中にある UTF-7 で
      エンコードされたコンテンツ (リクエスト URI など) には
      うまく動作しないからです。
    
    
    

   

   
    force-proxy-request-1.0, proxy-nokeepalive, proxy-sendchunked, proxy-sendcl
    

   
    これらの指示子は mod_proxy の挙動を変更します。
   詳細は mod_proxy のドキュメントをご参照ください。

    クライアントに関する既知の問題に対処するために、以下の行を
        httpd.conf に入れることを推奨しています。
    
        
    古いバージョンの Apache では、クライアントの問題に対応するために
        httpd.conf に次の行を加えるよう推奨されていましたが、
        今となっては、問題としていたクライアントは実際には見かけることは
        なくなってきたので、この設定はもはや必要ないかもしれません。

    Sous Windows, Apache est habituellement lancé en tant que
    service. Pour plus de détails, voir Démarrer Apache en tant
    que service.
    

    
    Sous Unix, le programme httpd
    est lancé en mode démon et s'exécute de manière permanente en
    arrière-plan pour gérer les requêtes.  Ce document décrit comment invoquer
     httpd.
    

    


    top
    

    

    Comment Apache démarre
    

    
    Si la directive Listen
    spécifiée dans le fichier de configuration est à sa valeur par défaut
    de 80 (ou tout autre port inférieur à 1024), il est nécessaire de
    posséder les privilèges root pour pouvoir démarrer apache, et lui
    permettre d'être associé à ce port privilégié. Lorsque le serveur est
    démarré, il effectue quelques opérations préliminaires
    comme ouvrir ses fichiers de log, puis il lance plusieurs processus
    enfants qui ont pour rôle d'écouter et de répondre aux
    requêtes des clients. Le processus httpd principal
    continue à s'exécuter sous l'utilisateur root, tandis que les processus
    enfants s'exécutent sous un utilisateur aux privilèges restreints.
    Ceci s'effectue par la voie du
    Module Multi-Processus (MPM).
    

    
    Il est recommandé d'utiliser le script de contrôle
    apachectl pour invoquer l'exécutable
    httpd. A cet effet, ce script définit certaines variables
    d'environnement nécessaires pour permettre à
    httpd de fonctionner correctement sous certains systèmes
    d'exploitation.
    apachectl accepte des arguments de ligne de
    commande ;
    ainsi toute option de httpd peut aussi être utilisée avec
    apachectl.  Vous pouvez aussi éditer directement le
    script apachectl en modifiant la variable
    HTTPD située en début de script pour spécifier la
    localisation du binaire httpd et tout argument de ligne
    de commande que vous souhaitez voir systématiquement présent.
    

    
    La première chose qu'effectue httpd quand il est
    invoqué est de localiser et lire le fichier de configuration
    httpd.conf. La localisation de ce fichier est définie à la
    compilation, mais il est possible d'en spécifier une autre à
    l'exécution en utilisant l'option de ligne de commande -f comme suit:
    


    /usr/local/apache2/bin/apachectl -f
      /usr/local/apache2/conf/httpd.conf
    

    
    Si tout se passe bien pendant le démarrage, le serveur va se dissocier
    du terminal et l'invite de commande réapparaîtra presque immédiatement.
    Ceci indique que le serveur a démarré et est en cours d'exécution.
    À partir de ce moment, vous pouvez utiliser votre navigateur pour vous connecter
    au serveur et afficher la page de test située dans le répertoire défini
    par la directive DocumentRoot
    

    top
    

    

    Erreurs en cours de démarrage
    

    
    Si un problème fatal survient pendant le démarrage
    d'Apache, ce dernier va
    afficher un message décrivant le problème sur la console ou
    enregistrer ces informations dans le fichier défini par la directive
    ErrorLog avant de quitter.
    Un des messages d'erreur les plus courants est "Unable
    to bind to Port ...". Ce message d'erreur est habituellement
    provoqué par :
    

    
      
      
    • Une tentative de démarrage du serveur avec un port privilégié sans
      être connecté root
      • 

      
    • Une tentative de démarrage du serveur alors qu'une autre instance
      d'Apache ou un autre serveur web est déjà associé au même port.
      • 
    
    

    
    Pour plus d'instructions de dépannage, consultez la
    FAQ Apache.
    

    top
    

    

    Lancement au démarrage du système
    

    
    Si vous souhaitez que votre serveur web soit automatiquement
    disponible après
    un redémarrage du système, vous devez ajouter un appel à
    apachectl à vos
    fichiers de démarrage système (en général rc.local ou un
    fichier dans un répertoire rc.N), ce qui démarrera Apache sous
    l'utilisateur root. Avant de faire ceci, assurez-vous que votre serveur
    soit correctement configuré en ce qui concerne la sécurité et les
    restrictions d'accès.
    

    
    Le script apachectl est conçu pour fonctionner
    comme un script d'initialisation SysV standard ; il accepte les arguments
    start, restart, et stop
    et les traduit en signaux appropriés pour
    httpd, et il suffit en général d'installer
    un lien vers
    apachectl dans le répertoire d'initialisation approprié.
    Mais prenez soin de vérifier les besoins exacts de votre système
    en la matière.

    Если вы абсолютный новичок в работе с HTTP-сервером Apache или 
в запуске веб-сайтов вообще, вы можете не знать с чего начать или какие
вопросы задавать. Этот документ познакомит вас с основами.
    

    


    top
    

    

    Клиенты, серверы и URL-адреса
    



    Адреса в Интернете записываются с помощью URL — Uniform Resource
Locator (унифицированный указатель ресурса), который указывает на
используемый протокол (например, http), имя сервера
(например, www.apache.org), URL-путь (например,
/docs/current/getting-started.html) и, возможно,
строку запроса (например, ?arg=value), используемую для
передачи серверу дополнительных аргументов.
    


    Клиент (например, веб-браузер) подключается к серверу
(например, вашему HTTP-серверу Apache), используя определённый протокол,
и отправляет запрос на ресурс, используя URL-путь.
    


    URL-путь может обозначать множество вещей на сервере. Это может быть
файл (как getting-started.html), обработчик
(как server-status) или файл какой-то
программы (как index.php). Мы рассмотрим это подробней ниже,
в разделе Контент веб-сайта.
    


    Сервер отправляет ответ, содержащий код состояния и,
опционально, тело ответа. Код состояния указывает, был ли запрос успешно
обработан, а если нет, то какая ошибка произошла.
Это говорит клиенту, что он должен делать с ответом.
Вы можете прочитать о возможных кодах ответа на 

Вики HTTP-сервера Apache.
    


    Детали транзакции и условия возникновения ошибки записываются
в файлы журналов. Это описывается более подробно ниже, в разделе
Файлы журналов и устранение неполадок.
    


    top
    

    

    Имена хостов и DNS
    



    Для того чтобы соединиться с сервером, клиент сначала должен преобразовать
имя сервера в IP-адрес — место в Интернете, где находится сервер.
Таким образом, чтобы ваш веб-сервер был доступен, необходимо,
чтобы имя сервера было в DNS.
    


    Если вы не знаете как это сделать, вам нужно обратиться к сетевому
администратору или поставщику услуг Интернета (провайдеру).
Они могут сделать это для вас.
    


    Несколько хостов могут указывать на один и тот же IP-адрес,
а один физический сервер может иметь больше одного IP-адреса.
Таким образом на одном физическом сервере вы можете запустить больше одного
сайта с помощью особенности: виртуальные хосты.
    


    Если вы тестируете сервер, не имеющий выхода в Интернет, можете поместить
имена хостов в файл hosts для того что бы имя разрешалось локально.
Например, вы можете добавить запись для отправки запросов к
www.example.com на локальный компьютер, для тестирования.
Эта запись будет выглядеть так:
    


    
127.0.0.1 www.example.com

    


    Файл hosts, скорее всего, расположен в /etc/hosts или 
C:\Windows\system32\drivers\etc\hosts.
    


    Вы можете узнать больше о файле 
hosts и больше о
DNS.
    

    top
    

    

    Файлы конфигурации и директивы
    



    HTTP-сервер Apache настроен с помощью простых текстовых файлов.
Эти файлы могут располагаться в разных местах, в зависимости от того как вы 
установили сервер. Общие места расположения файлов можно найти в 
Вики
HTTP-сервера Apache. Если вы установили httpd из исходного кода,
то расположение файлов конфигурации по умолчанию следующее:
/usr/local/apache2/conf.
По умолчанию файл конфигурации называется httpd.conf.
Это тоже может варьироваться в сторонних дистрибутивах сервера.
    


    Конфигурация часто разбивается на несколько небольших файлов, для
удобства управления. Эти файлы загружаются через директиву
Include.
Имена или расположения этих файлов конфигурации
могут сильно отличаться от одной установки к другой.
Расположите и разделите эти файлы наиболее подходящим для
вас образом. Если расположение файлов по умолчанию,
не имеет смысла для вас, не стесняйтесь изменить его.
    


    Сервер настраивается путём размещения 
директив конфигурации в этих файлах конфигурации.
Директива — это ключевое слово с одним или несколькими аргументами,
устанавливающими её значение.
    


    На вопрос: «Где я должен прописать эту директиву?» – обычно
отвечают, там где ты хочешь использовать её. Если это глобальная настройка,
она должна располагаться в конфигурационном файле вне разделов
<Directory>,
<Location>,
<VirtualHost> или других
разделов. Если настройка относится только к конкретному каталогу,
значит она должна быть внутри секции
<Directory>,
которая описывает этот каталог, и так далее.
Смотри документ Разделы конфигурации
с подробным описанием вышеуказанных разделов.
    


    В дополнение к основному файлу конфигурации, некоторые директивы могут
располагаться в файлах .htaccess, расположенных в папках с
контентом. Файлы .htaccess в первую очередь предназначены для
людей у которых нет доступа к главному конфигурационному файлу сервера.
Вы можете узнать больше о файлах .htaccess в инструкции
.htaccess.
    


    top
    

    

    Контент веб-сайта
    



    Содержимое сайта может принимать различные формы, но в широком смысле
разделяется на статический и динамический контент.
    


    Статический контент — это, например, HTML-файлы, файлы изображений,
CSS-файлы и другие файлы, которые просто лежат на диске.
Директива DocumentRoot указывает
где в вашей файловой системе, вы должны разместить эти файлы.
Эта директива устанавливается глобально или отдельно для каждого
виртуального хоста. Посмотрите в своём файле(ах) конфигурации,
чтобы узнать, как именно эта директива используется на вашем сервере.
    


    Обычно, когда запрашивается каталог, без указания имени файла, то будет
отдан документ с именем index.html. Например, если для директивы
DocumentRoot установлено значение /var/www/html 
и приходит запрос на адрес
http://www.example.com/work/,
то файл расположенный по пути
/var/www/html/work/index.html
будет отдан клиенту.
    


    Динамический контент — это всё что генерируется во время запроса и может 
изменяться от запроса к запросу. Существует множество способов создания
динамического контента. Различные обработчики
доступны для генерации содержимого. Могут быть написаны специальные
CGI программы для генерации контента на сайте.
    


    Для написания кода с разнообразным функционалом
могут использоваться сторонние модули, такие как mod_php.
Множество сторонних приложений, написанных на различных языках
программирования, и утилит доступны для скачивания и установки
на ваш HTTP-сервер Apache.
Поддержка сторонних продуктов выходит за рамки этой документации.
При необходимости вы должны самостоятельно найти их документацию
или форумы поддержки, где вы сможете получить ответы на свои вопросы.
    

    top
    

    

    Файлы журналов и устранение неполадок
    


    Для вас, как администратора HTTP-сервера Apache,
самые ценные активы — это файлы журналов (лог-файлы),
в частности, журнал ошибок. Исправление любой проблемы без журнала ошибок
можно сравнить с вождением автомобиля с закрытыми глазами.
    


    Расположение журнала ошибок задаётся директивой
ErrorLog,
которая может быть установлена глобально или для каждого виртуального хоста.
Записи в журнале ошибок расскажут вам, что и когда пошло не так.
Зачастую они также смогут подсказать, как что-то исправить.
Каждая запись в журнале ошибок содержит код ошибки,
по которому вы можете поискать в Интернете более подробное
описание того, как решить проблему.
Вы также можете настроить журнал ошибок так, чтобы в него записывался
идентификатор журнала, который можно сопоставить с записями в журнале
доступа — это поможет определить, какой запрос какую ошибку вызвал.
    


    Больше о логирование вы можете узнать в
документации о журналах.
    

    top
    

    

    Что дальше?
    



    Теперь, когда вы знакомы с основами, пора двигаться дальше.
    


    Этот документ содержит только базовую информацию.
Мы надеемся, что она поможет вам начать работу,
но есть множество других вещей, о которых вам, возможно, нужно узнать.

    Éste documento hace referencia a la compilación y la instalación del Apache 
    HTTP Server sólo para los sistemas Unix y  tipo Unix. Para la compilación e instalación en Windows  ir a  Usando Apache HTTP Server con Microsoft
    Windows y Compilando Apache para Microsoft Windows.
    Para otras plataformas visite la documentación sobre plataformas.
    

    
    Apache httpd usa libtool y autoconf
    para crear un entorno de compilación que se parece a muchos otros proyectos de código abierto
    

    
    Si está actualizando desde una versión menor a la siguiente (por
    ejemplo, 2.4.8 a 2.4.9), pasa a la sección de  actualización.

    Descripción general para los impacientes
    

    
    
      
      
    
        Descarga

        Descarga la última versión 
          desde 
          http://httpd.apache.org/download.cgi
        
      
    

      
    
        Extraer

        $ gzip -d httpd-NN.tar.gz
    
         $ tar xvf httpd-NN.tar
    
         $ cd httpd-NN    		
      
    

      
    
        Configura

        $ ./configure --prefix=PREFIX
        
      
    

      
    
        Compila

        $ make 
      
    

      
    
        Instala

        $ make install 
      
    

      
    
        Personalizalo

        $ vi PREFIX/conf/httpd.conf 
      
    

      
    
        Prueba

        $ PREFIX/bin/apachectl -k start
        
      
    
    
    

    
    NN hay que reemplazarlo por el número de la versión menor, y PREFIX hay que reemplazarlo por la ruta en la que se va a instalar Apache. Si no especifica ningún valor en PREFIX, el valor por defecto que se toma es /usr/local/apache2.
    

    
    Cada parte del proceso de configuración e instalación se describe detalladamente más abajo, empezando por los requisitos para compilar e instalar Apache.
    

    top
    

    

    Requisitos
    

    
    Estos son los requisitos necesarios para compilar Apache:
    

    
    
      
    APR y APR-Util
    
      
    Asegúrate de que tiene instalado ya en su sistema APR y APR-Util. Si no es así, o no quiere utilizar la versión que le proporciona el sistema, puede descargar la última versión de ambos APR y APR-Util de
      Apache APR, descomprimelo en
       /httpd_source_tree_root/srclib/apr y /httpd_source_tree_root/srclib/apr-util
      (cerciórate de que no existen directorios con números de versiones; por ejemplo,
      la distribución de APR debe estar en /httpd_source_tree_root/srclib/apr/) y usa el comando
      ./configure --con-las-opciones-incluidas-en-apr.
      En algunas plataformas deberás instalar la parte correspondiente a los paquetes 
      -dev para permitir que httpd se genere contra la instalación de la copia de APR y APR-Util.
    

      
    Librería Compatible de expresiones regulares de Perl (PCRE)
    
      
    Esta librería es requerida, pero ya no incluido con httpd.
      Descarga el código fuente de http://www.pcre.org,
      o instala un Port o un  Paquete. Si la distrubución de su sistema no puede encontrar el escript pcre-config instalado por PCRE, seleccione utilizando el parámetro--with-pcre.En algunas plataformas,
      deberás instalar la correspondiente versión -dev
      del paquete para permitir a httpd que se genere contra la instalación de la copia del PCRE que se ha instalado.
    

      
    Espacio en disco
     
      
    Compruebe que tiene disponibles al
      menos 50 MB de espacio libre en disco. Después de la
      instalación, Apache ocupa aproximadamente 10 MB. No
      obstante, la necesidad real de espacio en disco varía
      considerablemente en función de las opciones de
      configuración que elija y de los módulos externos que
      use, y como no del tamaño de la página web
    

      
    Systema de compilación ANSI-C
    
      
    Compruebe que tiene instalado un compilador de ANSI-C. Se recomienda el Compilador GNU C
      (GCC) de la Free Software
      Foundation (FSF) es el recomendado. Si no tiene instalado el GCC, entonces compruebe que
      el compilador que va a utilizar cumple con los estándares
      ANSI. Además, su PATH debe contener la
      ubicación donde de encuentran las herramientas básicas
      para compilar tales como make.
    

      
    Ajuste exacto del reloj del sistema
     
      
    Los elementos
      del protocolo HTTP están expresados según la hora del
      día. Por eso, si quiere puede investigar como instalar alguna
      utilidad para sincronizar la hora de su sistema. Para esto,
      normalmente, se usan los programas ntpdate o
      xntpd, que están basados en el protocolo
      "Network Time Protocol" (NTP). Consulte elsitio web de NTP
       para obtener más información sobre NTP y los
      servidores públicos de tiempo.
    

      
    Perl 5[OPCIONAL]
    
      
    Para algunos de los scripts de soporte comoapxs o dbmmanage (que están
      escritos en Perl) es necesario el intérprete de Perl 5 (las
      versiones 5.003 o posteriores son suficientes). Si el escript
      configure no se encuentra, no podrá usar los
	  escripts correspondientes que lo necesiten. Pero por supuesto
	  podrás compilar y usar Apache httpd.

    Descargar
    

    
    Puede descargar Apache desde la sección de
    descargas del sitio web de Apache el cual tiene varios
    mirrors. Para la mayoría de los usuarios de Apache que tienen
    sistemas tipo Unix, se recomienda que se descarguen y compilen el
    código fuente. El proceso de compilación (descrito
    más abajo) es fácil, y permite adaptar el servidor
    Apache a sus necesidades. Además, las versiones de
    disponibles en archivos binarios no están siempre actualizadas
    con las últimas modificaciones en el código fuente. Si se
    descarga un binario, siga las instrucciones contenidas en el
    archivo INSTALL.bindist incluido en la
    distribución
    

    
    Después de la descarga, es importante que verifique que el
    archivo descargado del servidor HTTP Apache está completo y
    sin modificaciones.  Esto puede hacerlo comparando el archivo
    descargado (.tgz) con su firma PGP. Instrucciones detalladas de
    cómo hacer esto están disponibles en  la
    sección de descargas junto con un ejemplo de cómo usar
    PGP.
    


    top
    

    

    Descomprimir
    

    
    Extraer el código fuente del archivo .tgz del Servidor Apache HTTP que acabada 
      de descargar es muy fácil. Ejecute los siguientes comandos:
    


    
$ gzip -d httpd-NN.tar.gz
    
$ tar xvf httpd-NN.tar

    

    
    Estos comandos crearán un nuevo directorio dentro del
    directorio en el que se encuentra y que contendrá el
    código fuente de distribución. Debe cambiarse a ese
    directorio con cd para proceder a compilar el
    servidor Apache.
    

    top
    

    

    Configuración de la estructura de
directorios
    

    
    El siguiente paso es configurar la estructura de directorios
    para su plataforma y sus necesidades personales. Esto se hace
    usando el script configure incluido en el directorio
    raíz de la distribución que acaba de descargar. (Los
    desarrolladores que se descarguen la versión del CVS de la
    estructura de directorios necesitarán tener instalados
    autoconf y libtool, y necesitarán
    ejecutar buildconf antes de continuar con los
    siguientes pasos. Esto no es preciso para las versiones
    oficiales.)
    

    
    Para configurar la estructura de directorios a partir del
    código fuente usando las opciones por defecto, solo tiene que
    ejecutar ./configure.Para cambiar las opciones por
    defecto, configure acepta una serie de variables y
    opciones por la línea de comandos.
    

    
    La opción más importante es --prefix
    que es el directorio en el que Apache va a ser instalado después,
    porque Apache tiene que ser configurado para el directorio que se
    especifique para que funcione correctamente.  Es posible lograr un
    mayor control del lugar donde se van a instalar los ficheros de
    Apache con otras opciones de
    configuración.
    

    
    Llegados a este punto, puede especificar que características
    o funcionalidades quiere incluir en Apache activando o
    desactivando modules.Apache vine con una amplia
    selección de módulos incluidos por defecto. Que serán compilados como .
    Objetos Compartidos (DSOs) Que pueden ser activados
    o desactivados en tiempo de ejecución.
    También puede elegir por compilar módulos de forma estática usando las opciones
    --enable-module=static.
    



    
    Se pueden activar otros módulos usando la opción 
    --enable-module, where
    module es el nombre del módulo sin el
    mod_ y convirtiendo los guiones bajos que tenga en
    guiones normales.  Del mismo modo, puede desactivar los módulos con la
    opción --disable-module. Tenga cuidado al utilizar esta opción, ya que
    configure no le avisará si el módulo que especifica no existe;
    simplemente ignorará esa opción.
    

    
    Además, a veces es necesario pasarle al script
    configure información adicional sobre donde esta
    su compilador, librerías o ficheros de cabecera.  Esto se puede
    hacer, tanto pasando variables de entorno, como pasandole opciones
    a configure.  Para más información, consulte el manual de
    configure. O use configure con la 
    opción --help.
    

     
    Para que se haga una idea sobre las posibilidades que tiene,
    aquí tiene un ejemplo típico que configura Apache para
    la ruta /sw/pkg/apache con un compilador y unos flags
    determinados, y además, con dos módulos adicionales
    mod_ldap y mod_ldap para
    cargarlos después a través del mecanismo DSO:
    


    
      $ CC="pgcc" CFLAGS="-O2" \
    
       ./configure --prefix=/sw/pkg/apache \
    
       --enable-ldap=shared \
    
       --enable-lua=shared

    

    
    Cuando se ejecuta configure se comprueban que
    características o funcionalidades están disponibles en
    su sistema y se crean los Makefiles que serán usados a continuación
    para compilar el servidor. Esto tardará algunos minutos.
    

    
    Los detalles de todas las opciones de configure están disponibles
    en el manual de configure .
    
  
    top
    

    

    Build
    

    
    Ahora puede compilar las diferentes partes que forman Apache
    simplemente ejecutando el siguiente comando:
    


    $ make
    

    
    Por favor sea paciente llegado a este punto, ya que una configuración básica lleva unos minutos
      para su compilación, y el tiempo puede variar mucho dependiendo de su hardware 
      y del número de módulos que haya habilitado para la compilación.(Se recomienda añadir al make el
      parámetro -j3 como mínimo para que vaya más rápido)
    

    top
    

    

    Instalar
    

    
    Ahora es el momento de instalar el paquete en el diretorio
    elegido en PREFIX (consulte más arriba la opción
    --prefix) ejecutando:
    


    $ make install
    

    
    Este paso requiere de forma típica privilegios de root, ya que 
      el directorio de PREFIX es normalmente un directorio con 
      restricciones de permisos escritura.
    

    
    Si lo que esta es sólo actualizando, la instalación no sobreescribirá los
      archivos de configuración.
    

    top
    

    

    Personalizar APACHE
    

    
    Tras la instalación puede personalizarla, editando los 
    archivos de configuracion  en el directorio de
    PREFIX/conf/.
    


    $ vi PREFIX/conf/httpd.conf
    

    
    Échele un vistazo al Manual de Apache que está en
    PREFIX/docs/manual/ o consulta http://httpd.apache.org/docs/2.4/ para la versión más
    reciente de este manual y su completa
    referencia de las directivas de configuracion disponibles.
    

    top
    

    

    Comprobar que la instalación
funciona
    

    
    Ahora puedes  ejecutar tu Apache
    HTTP server ejecutando directamente:
    


    $ PREFIX/bin/apachectl -k start
    

    
    Ahora debe poder acceder a su primer documento
    bajo la URL http://localhost/. La página o documento que ve se encuentra en
    DocumentRoot,
    que por norma general casi siempre será PREFIX/htdocs/.
    Si quiere  parar el servidor, puede hacerlo ejecutando:
    


    $ PREFIX/bin/apachectl -k stop
    

    top
    

    

    Actualizar una instalación previa
    

    
    El primer paso para actualizar una instalación anterior es
    leer las especificaciones de la versión y el fichero
    CHANGES en la distribución de código fuente
    que ha descargado para encontrar los cambios que puedan afectar a
    su instalación actual. Cuando el cambio sea entre versiones
    mayores(por ejemplo, de la 2.0 a 2.2 o de la 2.2 a la 2.4),
    entonces es más probable que haya diferencias importantes en
    la compilación y en la ejecución que necesitarán
    ajustes manuales. Todos los módulos necesitarán
    también ser actualizados para adaptarse a los cambios en el
    interfaz de programación (API) de módulos.
    

    
    Actualizando de una versión menor a la siguiente
      (por ejemplo, de la 2.2.55 a la  2.2.57) es mas fácil. El prodeso de realizar el make install
    no sobreescribirá ninguno de tus documentos existentes,archivos
    log, o archivos de configuración. De hecho, los desarrolladores están haciendo los esfuerzos
    necerarios para evitar cambios que generen incompatibilidades en las opciones de
    configure, la configuración al ser ejecutado, o el módulo de la API
    entre versiones menores. En la mayor parte de los casos debe poder usar un
    comando configure idéntico, un fichero de
    configuración idéntico, y todos sus módulos deben
    seguir funcionando.
    

    
    Para actualizar entre versiones menores, empecemos encontrando el archivo de configuración
    config.nice el directorio de instalación del servidor
    o en el directorio raiz del código fuente de tu antigua instalación. Este archivo contendrá
    los parámetros exactos para pasarle al 
    configure que usaste anteriormente para configurar tus directorios.
    Entonces, para actualizar su instalación de una versión a la
    siguinete, solo tiene que copiar el archivo
    config.nice a la estructura de directorios del
    código fuente de la nueva versión, editarlo, hacer
    cualquier cambio que desee, y ejecutarlo :
    

    
    
    $ ./config.nice
    
    $ make
    
    $ make install
    
    $ PREFIX/bin/apachectl -k graceful-stop
    
    $ PREFIX/bin/apachectl -k start
    
    
    

    
    Tenga en cuenta que antes de poner una nueva
    versión de Apache en producción, debe siempre probarla
    antes en un entorno de pruebas. Por ejemplo, puede instalar y ejecutar la
    nueva versión junto con la antigua usando un
    --prefix diferente y un puerto diferente (modificando
    la directiva Listen)
    para comprobar que no existe ninguna incompatibilidad antes de
    hacer la actualización definitiva.
    

    
    Puede pasarle argumentos adicionales a config.nice,
    que se agregarán a susopciones originales de configure:
    

    
    
    $ ./config.nice --prefix=/home/test/apache --with-port=90
    
    

    top
    

    

    Paquetes de terceros
    

    
    Un gran número de terceros proporcionan sus propias 
    distribuciones empaquetadas del Apache HTTP Server para su
    instalación en plataformas específicas. Esto incluye las distintas
    distribuciones de Linux, varios paquetes de Windows de terceros,
    Mac OS X, Solaris, y muchos más.
    

    
    Nuestra licencia de software no sólo permite, sino que anima, 
    este tipo de redistribución. Sin embargo, se da lugar a una situación
    en la que el diseño y la configuración de los valores predeterminados
    de la instalación del servidor pueden diferir de lo que se indica
    en la documentación. Mientras lamentablemente, esta situación no es probable que cambie a corto plazo.
    

    
    Una descripción
    de estas distribuciones de terceros  está siendo actualizada en el servidor de la WIKI de HTTP
    Server, y debería reflejar el actual estado de éstas distribuciones de terceros. 
    Sin embargo, tendrá que familiarizarse con los procedimientos de gestión
    e instalación de paquetes de su plataforma (SO) en particular.

    Ce document complète la documentation de référence des modules
    mod_cache, mod_cache_disk,
    mod_file_cache et du programme htcacheclean.
    Il décrit l'utilisation des fonctionnalités de mise en
    cache du serveur HTTP Apache
    pour accélérer les services web et proxy, tout en évitant les problèmes
    courants et les erreurs de configuration.
    
  
    


    top
    

    

    Introduction
    
    

    
    Le serveur HTTP Apache offre tout un ensemble de fonctionnalités
    de mise en cache qui ont été conçues pour améliorer les performances
    du serveur de différentes manières.
    

    
    
        
    Mise en cache HTTP à trois états RFC2616
    
        
    mod_cache et son module de fournisseur
	mod_cache_disk proposent une mise en cache
	intelligente de niveau HTTP. Le contenu proprement dit est
	stocké dans le cache, et mod_cache vise à respecter tous les
	en-têtes HTTP, ainsi que les options qui contrôlent la mise en
	cache du contenu comme décrit dans la Section
	13 de la RFC2616. mod_cache peut gérer des
	configurations de mise en cache simples, mais aussi complexes
	comme dans les cas où vous avez à faire à des contenus mandatés,
	à des contenus locaux dynamiques, ou lorsque vous avez besoin
	d'accélérer l'accès aux fichiers locaux situés sur disque
	supposé lent.
        
    

        
    Mise en cache d'objets partagés de forme clé/valeur à deux
	états
    
        
    
            L'API du cache d'objets partagés (socache)
	    et ses modules de fournisseurs
	    proposent une mise en cache d'objets partagés à base de
	    couples clé/valeur de niveau serveur. Ces modules sont
	    conçus pour la mise en cache de données de bas niveau comme
	    les sessions SSL et les données d'authentification. les
	    serveurs d'arrière-plan permettent le stockage des données
	    au niveau serveur en mémoire partagée, ou au niveau
	    datacenter dans un cache comme memcache ou distcache.
        
    

        
    Mise en cache de fichiers spécialisée
    
        
    
            mod_file_cache offre la possibilité de
	    précharger des fichiers en mémoire au démarrage du serveur,
	    et peut améliorer les temps d'accès et sauvegarder les
	    gestionnaires de fichiers pour les fichiers qui font l'objet
	    d'accès fréquents, évitant ainsi d'avoir à accéder au disque
	    à chaque requête.
        
    
    
    

    
    Pour tirer parti efficacement de ce document, les bases de HTTP doivent
    vous être familières, et vous devez avoir lu les sections
    Mise en correspondance des
    URLs avec le système de fichiers et
    Négociation sur le contenu
    du guide de l'utilisateur.
    

  
    top
    

    

    Mise en cache HTTP à trois états RFC2616
    

    

    
    Modules ApparentésDirectives Apparentées
    

    
    Le module mod_cache permet de tirer avantage du
    mécanisme de mise en cache en ligne faisant partie
    intégrante du protocole HTTP, et décrit dans la section
    13 de la RFC2616.
    

    
    A la différence d'un cache simple clé/valeur à deux états où le
    contenu est supprimé lorsqu'il est périmé, un cache HTTP comporte un
    mécanisme permettant de conserver temporairement un contenu périmé,
    de demander au serveur original si ce contenu périmé a été modifié,
    et dans le cas contraire de le rendre à nouveau valide.
    

    
    Une entrée d'un cache HTTP peut se présenter sous un de ces trois
    états :
    

    
    
    
    Frais
    
    
    
        Si un contenu est suffisamment récent (plus jeune que sa
	durée de fraîcheur), il est considéré comme
	frais. Un cache HTTP peut servir un contenu
	frais sans avoir à demander quoi que ce soit au serveur
	d'origine.
    
    
    
    Périmé
    
    
    
        
    Si le contenu est trop ancien (plus vieux que sa
	durée de fraîcheur), il est considéré comme
	périmé. Un cache HTTP doit contacter le serveur
	original pour vérifier si le contenu, même s'il est périmé, est
	encore à jour avant de le servir au client. Soit le serveur
	original va répondre en envoyant un contenu de remplacement si
	le contenu périmé n'est plus à jour, soit dans le cas idéal il
	renverra un code pour signaler au cache que le contenu est
	encore à jour, et qu'il est inutile de le générer ou de
	l'envoyer à nouveau. Le contenu repasse à l'état "frais" et le
	cycle continue.
    

        
    Le protocole HTTP permet au cache de servir des données
	périmées dans certaines circonstances, comme lorsqu'une
	tentative de rafraîchir une entrée depuis un serveur original
	se solde par un échec avec un code d'erreur 5xx, ou lorsqu'une
	autre requête est déjà en train d'essayer de rafraîchir la même
	entrée. Dans ces cas, un en-tête Warning est ajouté
	à la réponse.
    
    
    
    
    Non Existent
    
    
    
        Si le cache est plein, il se réserve la possibilité de supprimer
	des entrées pour faire de la place. Une entrée peut être
	supprimée à tout moment, qu'elle soit fraîche ou périmée.
	L'outil htcacheclean
	peut être utilisé à la demande, ou lancé en tant que démon afin
	de conserver la taille du cache ou le nombre d'inodes en deçà de
	valeurs spécifiées. Cet outil essaie cependant de
	supprimer les entrées périmées avant les entrées fraîches.
    
    
    
    

    
    Le fonctionnement détaillé d'un cache HTTP est décrit dans la Section
    13 de la RFC2616.
    

    
    Interaction avec le serveur
    
      

      
    Le module mod_cache interagit avec le serveur
      à deux niveaux possibles en fonction de la directive CacheQuickHandler :
      
    

      
    
        
    Phase de gestion rapide
    
        
    
          
    Cette phase se déroule très tôt au cours du traitement de
	  la requête, juste après l'interprétation de cette dernière. Si
	  le contenu se trouve dans le cache, il est servi immédiatement
	  et pratiquement tout le reste du traitement de la requête est
	  court-circuité.
    

              
    Dans ce scénario, le cache se comporte comme s'il avait
	      été "boulonné" à l'entrée du serveur.
    
              
              
    Ce mode possède les meilleures performances car la
	      majorité des traitements au niveau du serveur sont
	      court-circuités. Cependant, il court-circuite aussi les
	      phases d'authentification et d'autorisation du traitement
	      au niveau du serveur, et il doit donc être utilisé avec
	      prudence lorsque que ces phases sont importantes.
    

	      
    Les requêtes comportant un en-tête "Authorization"
	      (comme par exemple l'authentification HTTP basique) ne
	      peuvent être ni mises en cache, ni servies depuis ce
	      dernier lorsque mod_cache s'exécute dans
	      cette phase.
    
          
    
          
    Phase de gestion normale
    
          
    
              
    Cette phase se déroule très tard au cours du traitement
	      de la requête, en fait après toutes les phases de ce
	      traitement.
    

              
    Dans ce scénario, le cache se comporte comme s'il avait
	      été "boulonné" à la sortie du serveur.
    

              
    Ce mode offre la plus grande souplesse, car il permet
	      de faire intervenir la mise en cache en un point
	      précisément spécifié de la chaîne de filtrage, et le
	      contenu issu du cache peut être filtré ou personnalisé
	      avant d'être servi au client.
    
          
    
        
    

        
    Si l'URL ne se trouve pas dans le cache,
	mod_cache ajoutera un filtre à la chaîne de filtrage afin
	d'enregistrer la réponse dans le cache, puis passera la main
	pour permettre le déroulement normal de la suite du traitement
	de la requête. Si la mise en cache du contenu est autorisée, il
	sera enregistré dans le cache pour pouvoir être servi à nouveau
	; dans le cas contraire, le contenu sera ignoré.
    

        
    Si le contenu trouvé dans le cache est périmé, le module
	mod_cache convertit la requête en
	requête conditionnelle. Si le serveur original
	renvoie une réponse normale, elle est enregistrée dans le cache
	en lieu et place du contenu périmé. Si le serveur original
	renvoie une réponse "304 Not Modified", le contenu repasse à
	l'état "frais" et est servi par le filtre au lieu d'être
	sauvegardé.
    
    

    
    Amélioration du taux de présence dans le cache
    
      

      
    Lorsqu'un serveur virtuel est connu sous la forme d'un des
      nombreux alias du serveur, la définition de la directive
      UseCanonicalName à
      On peut augmenter de manière significative le nombre
      de correspondances positives dans le cache. Ceci est du au fait
      que la clé du cache contient le nom d'hôte du serveur virtuel.     
      Avec UseCanonicalName positionnée
      à On,
      les hôtes virtuels possédant plusieurs noms de serveur ou alias ne
      généreront pas d'entités de cache différentes, et le contenu sera mis en
      cache en faisant référence au nom d'hôte canonique.
    

    

    
    Durée de fraîcheur
    
      

       
    Un contenu bien formé destiné à être mis en cache doit déclarer
       explicitement une durée de fraîcheur via les champs
       max-age ou s-maxage de l'en-tête
       Cache-Control, ou en incluant un en-tête
       Expires.
    
      
      
    De plus, un client peut passer outre la durée de fraîcheur
      définie pour le serveur original en ajoutant son propre en-tête
      Cache-Control à la requête. Dans ce cas, c'est la
      durée de fraîcheur la plus basse entre la requête et la réponse
      qui l'emporte.
    

      
    Lorsque cette durée de fraîcheur est absente de la requête ou
      de la réponse, une durée de fraîcheur par défaut s'applique. La
      durée de fraîcheur par défaut des entrées du cache est d'une heure
      ; elle peut cependant être facilement modifiée à l'aide de
      la directive CacheDefaultExpire.
    

      
    Si une réponse ne contient pas d'en-tête Expires mais
      inclut un en-tête Last-Modified, mod_cache
      peut déduire une durée de fraîcheur en se basant sur une
      heuristique, qui peut être contrôlée via la directive CacheLastModifiedFactor.
    

      
    Pour les contenus locaux, ou les contenus distants qui ne
      spécifient pas leur propre en-tête Expires,
      mod_expires permet de régler finement la durée de
      fraîcheur via les paramètres max-age et
      Expires.
    

      
    On peut aussi contrôler la durée de fraîcheur maximale en utilisant
      la directive CacheMaxExpire.
    

    

    
    Guide succinct des requêtes conditionnelles
    
      

     
    Lorsqu'un contenu du cache est périmé, httpd modifie la requête
     pour en faire une requête conditionnelle
    

      
    Lorsque la réponse originale du cache contient un en-tête
      ETag, mod_cache ajoute un en-tête
      If-None-Match à la requête envoyée au serveur
      d'origine. Lorsque la réponse originale du cache contient un en-tête
      Last-Modified, mod_cache ajoute un en-tête
      If-Modified-Since à la requête envoyée au serveur
      d'origine. Dans ces deux cas, la requête devient une requête
      conditionnelle.
    

      
    Lorsqu'un serveur d'origine reçoit une requête conditionnelle,
      il vérifie si le paramètre Etag ou Last-Modified a été modifié en
      fonction des paramètres de la requête. Si ce n'est pas le cas, il
      répondra avec le message lapidaire "304 Not Modified". Ceci
      informe le cache que le contenu est périmé mais encore à jour, et
      peut être utilisé tel quel pour les prochaines requêtes jusqu'à ce
      qu'il atteigne à nouveau sa date de péremption.
    

      
    Si le contenu a été modifié, il est servi comme s'il s'agissait
      d'une requête normale et non conditionnelle.
    

      
    Les requêtes conditionnelles offrent deux avantages. D'une
      part, il est facile de déterminer si le contenu du serveur
      d'origine correspond à celui situé
      dans le cache, et ainsi d'économiser la consommation de ressources
      nécessaire au transfert du contenu dans son ensemble.
    

      
    D'autre part, un serveur d'origine bien conçu sera configuré de
      telle manière que les requêtes conditionnelles nécessitent pour
      leur production bien moins de ressources qu'une réponse complète.
      Dans le cas des fichiers statiques, il suffit en général d'un
      appel système de type stat() ou similaire pour
      déterminer si la taille ou la date de modification du fichier a
      été modifiée. Ainsi, même un contenu local pourra être servi plus
      rapidement depuis le cache s'il n'a pas été modifié.
    
      
      
    Il serait souhaitable que tous les serveurs d'origine
      supportent les requêtes conditionnelles, car dans le cas
      contraire, ils répondent comme s'il s'agissait d'une requête
      normale, et le cache répond comme si le contenu avait été
      modifié et enregistre ce dernier. Le cache se comporte alors
      comme un simple cache à deux état, où le contenu est servi s'il
      est à jour, ou supprimé dans le cas contraire.
    
    

    
    Que peut-on mettre en cache ?
    
      

      
    La liste complète des conditions nécessaires pour qu'une
      réponse puisse être enregistrée dans un cache HTTP est fournie
      dans la section
      13.4 Response Cacheability de la RFC2616, et peut se résumer
      ainsi :
    

      
      
        
    1. La mise en cache doit être activée pour cette URL. Voir les
	directives CacheEnable et CacheDisable.
      2. 

        
    2. Si la reponse possède un code de statut HTTP autre que 200, 203, 300, 301
	ou 410, elle doit aussi comporter un en-tête "Expires" ou
	"Cache-Control".
      3. 

        
    3. La requête doit être de type HTTP GET.
      4. 

        
    4. Si la réponse contient un en-tête "Authorization:", elle doit aussi
	contenir une option "s-maxage", "must-revalidate" ou "public"
	dans l'en-tête "Cache-Control:".
      5. 

        
    5. Si l'URL contient une chaîne de requête
	(provenant par exemple d'une méthode GET de formulaire HTML), elle ne
	sera pas mise en cache, à moins que la réponse ne
	spécifie explicitement un délai d'expiration via un
	en-tête "Expires:" ou une directive max-age ou s-maxage de
	l'en-tête "Cache-Control:" comme indiqué dans les
	sections 13.2.1. et 13.9 de la RFC2616.
      6. 

        
    6. Si la réponse a un statut de 200 (OK), elle doit aussi contenir
	au moins un des en-têtes "Etag", "Last-Modified" ou
        "Expires", ou une directive max-age ou s-maxage de
	l'en-tête "Cache-Control:", à moins que la directive
        CacheIgnoreNoLastMod
        ne précise d'autres contraintes.
      7. 

        
    7. Si la réponse contient l'option "private" dans un en-tête
	"Cache-Control:", elle ne sera pas mise en cache à moins que la
	directive
        CacheStorePrivate
	ne précise d'autres contraintes.
      8. 

        
    8. De même, si la réponse contient l'option "no-store" dans un en-tête
        "Cache-Control:", elle ne sera pas mise en cache à moins que la
	directive
        CacheStoreNoStore
	n'ait été utilisée.
      9. 

        
    9. Une réponse ne sera pas mise en cache si elle comporte un en-tête
	"Vary:" contenant le caractère "*" qui correspond à toute
	chaîne de caractères.
      10. 
      
    
    

    
    Qu'est ce qui ne doit pas être mis en cache ?
    
      

      
    Le client qui crée la requête ou le serveur d'origine qui
      génère la réponse doit être à même de déterminer si le contenu
      doit pouvoir être mis en cache ou non en définissant correctement
      l'en-tête Cache-Control, et
      mod_cache sera alors en mesure de satisfaire les
      souhaits du client ou du serveur de manière appropriée.
      
    

      
    Les contenus qui varient au cours du temps, ou en fonction de
      particularités de la requête non prises en compte par la
      négociation HTTP ne doivent pas être mis en cache. Ce type de
      contenu doit se déclarer lui-même "à ne pas mettre en cache" via
      l'en-tête Cache-Control.
    
      
      
    Si le contenu change souvent, suite par exemple à une durée de
      fraîcheur de l'ordre de la minute ou de la seconde, il peut tout
      de même être mis en cache, mais il est alors fortement souhaitable
      que le serveur d'origine supporte correctement les
      requêtes conditionnelles afin que des réponses
      complètes ne soient pas systématiquement générées.
    

      
    Un contenu qui varie en fonction d'en-têtes de requête fournis
      par le client peut être mis en cache, sous réserve d'une
      utilisation appropriée de l'en-tête de réponse Vary.
    
    

    
    Contenu variable et/ou négocié
    
      

      
    Lorsque le serveur d'origine est configuré pour servir des
      contenus différents en fonction de la valeur de certains en-têtes
      de la requête, par exemple pour servir une ressource en plusieurs
      langages à partir d'une seule URL, le mécanisme de mise en cache
      d'HTTP permet de mettre en cache plusieurs variantes de la même
      page à partir d'une seule URL.
    
      
      
    Pour y parvenir, le serveur d'origine ajoute un en-tête
      Vary pour indiquer quels en-têtes doivent être pris
      en compte par un cache pour déterminer si deux variantes sont
      différentes l'une de l'autre.
    

      
    Si par exemple, une réponse est reçue avec l'en-tête Vary suivant,
    

      
    
Vary: negotiate,accept-language,accept-charset
      
    

      
    mod_cache ne servira aux demandeurs que le contenu
      mis en cache qui correspond au contenu des en-têtes accept-language et
      accept-charset de la requête originale.
    

      
    Plusieurs variantes d'un contenu peuvent être mises en cache
      simultanément ; mod_cache utilise l'en-tête
      Vary et les valeurs correspondantes des en-têtes de
      la requête spécifiés dans ce dernier pour
      déterminer quelle variante doit être servie au client.

    Exemples de configuration du cache
    

    

    
    Modules ApparentésDirectives Apparentées
    

    
    Mise en cache sur disque
    
      

      
    Le module mod_cache s'appuie sur des
      implémentations de stockage sous-jacentes spécifiques pour gérer
      le cache ; à ce titre, mod_cache_disk fournit le
      support de la mise en cache sur disque.
    

      
    En général, le module se configure comme suit :
    

      
    CacheRoot   "/var/cache/apache/"
CacheEnable disk /
CacheDirLevels 2
CacheDirLength 1
    


    
    Il est important de savoir que, les fichiers mis en cache étant stockés
    localement, la mise en cache par l'intermédiaire du système d'exploitation
    sera en général aussi appliquée à leurs accès. Si bien que même si les
    fichiers sont stockés sur disque, s'il font l'objet d'accès fréquents,
    il est probable que le système d'exploitation s'appliquera à ce qu'ils
    soient servis à partir de la mémoire.
    

    

    
    Comprendre le stockage dans le cache
    
      

      
    Pour stocker des entités dans le cache,
      le module mod_cache_disk crée une empreinte (hash) de 22
      caractères de l'URL qui a fait l'objet d'une requête. Cette empreinte
      comprend le nom d'hôte, le protocole, le port, le chemin et tout argument
      de type CGI associé à l'URL, ainsi que les éléments
      spécifiés dans l'en-tête Vary afin d'être sur que plusieurs URLs
      n'interfèrent pas entre elles.
    

      
    Chaque position de l'empreinte peut contenir un caractère
      choisi parmi 64 caractères différents, il y a donc
      64^22 possibilités pour une empreinte. Par exemple, une URL peut posséder
      l'empreinte xyTGxSMO2b68mBCykqkp1w. Cette empreinte est
      utilisée pour préfixer les noms de fichiers spécifiques à cette URL à
      l'intérieur du cache; cependant, elle est tout d'abord placée dans les
      répertoires du cache selon les directives
      CacheDirLevels et
      CacheDirLength.
    

      
    La directive
      CacheDirLevels
      définit le nombre de niveaux de sous-répertoires, et
      CacheDirLength
      le nombre de caractères composant le nom des sous-répertoires. Dans
      l'exemple donné plus haut, l'empreinte se trouvera à :
      /var/cache/apache/x/y/TGxSMO2b68mBCykqkp1w.
    

      
    Cette technique a pour but principal de réduire le nombre de
      sous-répertoires ou de fichiers contenus dans un répertoire particulier,
      car le fonctionnement de la plupart des systèmes de fichiers est ralenti
      quand ce nombre augmente. Avec la valeur "1" pour la directive
      CacheDirLength,
      il peut y avoir au plus 64 sous-répertoires à un niveau quelconque.
      Avec la valeur "2", il peut y en avoir 64 * 64, etc...
      A moins d'avoir une bonne raison pour ne pas le faire, l'utilisation de
      la valeur "1" pour la directive
      CacheDirLength
      est recommandée.
    

      
    Le paramétrage de la directive
      CacheDirLevels
      dépend du nombre de fichiers que vous pensez stocker dans le cache.
      Avec une valeur de "2" comme dans l'exemple donné plus haut,
      4096 sous-répertoires peuvent être créés au total. Avec 1 million de
      fichiers dans le cache, cela équivaut à environ 245 URLs mises en cache
      dans chaque répertoire.
    

      
    Chaque URL nécessite au moins deux fichiers dans le cache. Ce sont en
      général un fichier ".header", qui contient des meta-informations à propos
      de l'URL, comme la date de son arrivée à expiration,
      et un fichier ".data" qui est la copie exacte du contenu à servir.
    

      
    Dans le cas d'un contenu négocié via l'en-tête "Vary", un répertoire
      ".vary" sera créé pour l'URL en question. Ce répertoire contiendra de
      multiples fichiers ".data" correspondant aux différents contenus
      négociés.
    
    

    
    Maintenance du cache sur disque
    
      

      
    Le module mod_cache_disk n'effectue aucune
      régulation de l'espace disque utilisé par le cache, mais s'il
      s'arrête en douceur en cas d'erreur disque et se comporte alors
      comme si le cache n'avait jamais existé.
    

      
    Par contre l'utilitaire
      htcacheclean fourni avec
      httpd
      vous permet de nettoyer le cache périodiquement.
      Déterminer la fréquence à laquelle lancer htcacheclean et la taille souhaitée
      pour le cache est une tâche relativement complexe et il vous faudra de
      nombreux essais et erreurs pour arriver à sélectionner des valeurs
      optimales.
    

      
    htcacheclean opère selon deux
      modes. Il peut s'exécuter comme démon résident, ou être lancé
      périodiquement par cron. htcacheclean peut mettre une heure
      ou plus pour traiter de très grands caches (plusieurs dizaines de
      Gigaoctets) et si vous l'exécutez à partir de cron, il vous est
      conseillé de déterminer la durée typique d'un traitement, afin d'éviter
      d'exécuter plusieurs instances à la fois.
    

      
    Il est aussi conseillé d'attribuer un niveau de priorité "nice"
      approprié à htcacheclean de façon à ce qu'il n'effectue pas trop
      d'accès disque pendant le fonctionnement du serveur.
    

      
    
      
    
      Figure 1: Croissance
      typique du cache / séquence de nettoyage.
    

      
    Comme mod_cache_disk ne tient pas compte de l'espace
      utilisé dans le cache, vous devez vous assurer que
      htcacheclean est configuré de
      façon à laisser suffisamment d'"espace de croissance"
      à la suite d'un nettoyage.
    
    

    
    Cache en mémoire
    
      

      
    En utilisant le module mod_cache_socache,
      mod_cache peut mettre en cache des données à partir de
      diverses implémentations aussi nommées "fournisseurs". Par exemple, en
      utilisant le module mod_socache_memcache, on peut
      spécifier que c'est memcached qui doit
      être utilisé comme mécanisme de stockage sous-jacent.
    

      
    Typiquement, le module sera configuré comme suit :
    

      
    CacheEnable socache /
CacheSocache memcache:memcd.example.com:11211
    


      
    En outre, il est possible de spécifier plusieurs serveurs
      memcached en les ajoutant à la fin de la ligne
      CacheSocache memcache: et en les séparant par des virgules :
    

      
    CacheEnable socache /
CacheSocache memcache:mem1.example.com:11211,mem2.example.com:11212
    


      
    Divers autres fournisseurs mod_cache_socache utilisent
      aussi ce format. Par exemple :
    

      
    CacheEnable socache /
CacheSocache shmcb:/path/to/datafile(512000)
    


      
    CacheEnable socache /
CacheSocache dbm:/path/to/datafile

    Mise en cache à base de fichiers spécialisés
    

    

    
    Modules ApparentésDirectives Apparentées
    

    
    Sur les plateformes où le système de fichiers peut être lent, ou
    lorsque les descripteurs de fichiers sont gourmands en ressources,
    il est possible de précharger des fichiers en mémoire au démarrage
    du serveur.
    

    
    Sur les systèmes où l'ouverture des fichiers est lente, il est
    possible d'ouvrir le fichier au démarrage du serveur et de mettre en
    cache le descripteur de fichier. Ces options peuvent vous aider sur
    les systèmes où l'accès aux fichiers statiques est lent.
    

    
    Mise en cache des descripteurs de fichier
    
      

      
    Le processus d'ouverture d'un fichier peut être en soi une
      source de ralentissement, en particulier sur les systèmes de
      fichiers sur le réseau. httpd permet d'éviter ce ralentissement en
      maintenant un cache des descripteurs de fichiers ouverts pour les
      fichiers souvent servis. Actuellement, httpd fournit une seule
      implémentation de mise en cache des descripteurs de fichiers.
    

      
    CacheFile
    
        

        
    La forme la plus basique de mise en cache que propose httpd
	est la mise en cache des descripteurs de fichiers fournie par le
	module mod_file_cache. Plutôt que de mettre en
	cache le contenu des fichiers, ce cache maintient une table des
	descripteurs de fichiers ouverts. Les fichiers devant faire
	l'objet d'une mise en cache de ce type sont spécifiés dans le
	fichier de configuration via la directive CacheFile.
    

        
    La directive CacheFile informe httpd
	qu'il doit ouvrir le fichier lors de son démarrage et qu'il doit
	réutiliser le descripteur de fichier mis en cache pour tous les
	accès futurs à ce fichier.
    

        
    CacheFile /usr/local/apache2/htdocs/index.html
    


        
    Si vous désirez mettre en cache un grand nombre de fichiers
	de cette manière, vous devez vous assurer que le nombre maximal
	de fichiers ouverts pour votre système d'exploitation est défini
	à une valeur suffisante.
    

        
    Bien que l'utilisation de la directive CacheFile n'entraîne pas de
	mise en cache du contenu du fichier proprement dit, elle
	implique que si le fichier est modifié pendant l'exécution du
	serveur, ces modifications ne seront pas prises en compte. Le
	fichier sera toujours servi dans l'état où il se trouvait au
	moment du démarrage du serveur.
    

        
    Si le fichier est supprimé pendant l'exécution du serveur, ce
	dernier conservera le descripteur de fichier ouvert associé et
	servira le fichier dans l'état où il se trouvait au
	moment du démarrage du serveur. Cela signifie aussi que même si
	le fichier a été supprimé, et n'apparaît donc plus dans le
	système de fichiers, l'espace disque libéré ne sera disponible
	qu'une fois le serveur httpd arrêté et donc le descripteur de
	fichier fermé.
    
      

    

    
    In-Memory Caching
    
      

    
    Servir un contenu directement depuis la mémoire système est
    universellement reconnu comme la méthode la plus rapide. Lire des fichiers
    depuis un contrôleur de disque ou pire, depuis un réseau distant est plus
    lent de plusieurs ordres de grandeur. Les contrôleurs de disque réalisent
    en général des opérations mécaniques, et l'accès au réseau est limité par la
    bande passante dont vous disposez. Par contre, les temps d'accès à la
    mémoire sont de l'ordre de la nano-seconde.
    

    
    Cependant la mémoire système n'est pas bon marché; à capacité égale,
    c'est de loin le type de stockage le plus coûteux et il est important de
    s'assurer qu'elle est utilisée efficacement. Le fait de mettre en cache
    des fichiers en mémoire diminue d'autant la quantité de mémoire système
    disponible. Comme nous le verrons plus loin, ce n'est pas un problème en
    soi dans le cas de la mise en cache par l'intermédiaire du système
    d'exploitation, mais si l'on utilise la mise en cache en mémoire propre à
    httpd, il faut prendre garde à ne pas allouer trop de mémoire au cache.
    Sinon le système sera contraint d'utiliser le swap, ce qui dégradera
    sensiblement les performances.
    

      
    Mise en cache par l'intermédiaire du système d'exploitation
    
      

      
    Dans la plupart des systèmes d'exploitation modernes, c'est le noyau
      qui gère directement la mise en cache en mémoire des données relatives
      aux fichiers. C'est une fonctionnalité puissante, et les systèmes
      d'exploitation s'en acquittent fort bien pour la plus grande partie.
      Considérons par exemple, dans le cas de Linux, la différence entre le
      temps nécessaire à la première lecture d'un fichier et le temps
      nécessaire à sa deuxième lecture;
    

        
    colm@coroebus:~$ time cat testfile > /dev/null
real    0m0.065s
user    0m0.000s
sys     0m0.001s
colm@coroebus:~$ time cat testfile > /dev/null
real    0m0.003s
user    0m0.003s
sys     0m0.000s
    

      
    Même pour ce petit fichier, il y a une grande différence entre les
      temps nécessaires pour lire le fichier. Ceci est du au fait que le
      noyau a mis en cache le contenu du fichier en mémoire.
    

      
    Du fait de toujours pouvoir disposer de mémoire système, vous pouvez
      être assuré qu'il y aura de plus en plus de contenus de fichiers stockés
      dans ce cache. Ceci peut s'avérer une méthode de mise en cache en mémoire
      très efficace, et ne nécessite aucune configuration supplémentaire
      de httpd.
    

      
    De plus, comme le système d'exploitation sait si des fichiers
      ont été
      supprimés ou modifiés, il peut effacer automatiquement des contenus de
      fichiers du cache lorsque cela s'avère nécessaire. Ceci constitue un gros
      avantage par rapport à la mise en cache en mémoire
      de httpd qui n'a
      aucune possibilité de savoir si un fichier a été modifié.
    
      

    
    En dépit des performances et des avantages de la mise en cache
    automatique par le système d'exploitation, la mise en cache en mémoire
    peut être effectuée plus efficacement par httpd dans certaines
    circonstances.
    

    
    Mise en cache à l'aide de la directive MMapFile
    
      

      
    La directive MMapFile
      fournie par le module mod_file_cache vous permet de
      demander à httpd de charger un contenu de fichier statique en mémoire
      lors de son démarrage (à l'aide de l'appel
      système mmap). httpd
      utilisera le contenu chargé en mémoire pour satisfaire ultérieurement
      toutes les demandes d'accès à ce fichier.
    

        
    MMapFile /usr/local/apache2/htdocs/index.html
    


      
    Comme dans le cas de la directive
      CacheFile, toute
      modification du fichier ne sera plus prise en compte par httpd une fois
      ce dernier démarré.
    

      
     La directive
      MMapFile ne gardant
      pas la trace de la quantité de mémoire qu'elle alloue, vous devez prendre
      garde de ne pas en abuser. Chaque processus enfant de httpd utilisant
      sa propre réplique de la mémoire allouée, il est donc d'une importance
      critique de s'assurer que les fichiers chargés ne sont pas d'une taille
      trop importante afin d'épargner au système l'utilisation du swap.

    Considérations sur la sécurité
    
    

    
    Autorisation et contrôle d'accès
    
      

      
    Utiliser mod_cache revient sensiblement à la même
      chose qu'avoir un mandataire inverse intégré (reverse-proxy). Les requêtes
      seront servies par le module de mise en cache sauf si ce dernier
      détermine qu'un processus d'arrière-plan doit être appelé. La mise en
      cache de ressources locales modifie considérablement le modèle de
      sécurité de httpd.
    

      
    Comme le parcours de la hiérarchie d'un système de fichiers pour
      examiner le contenu d'éventuels fichiers
      .htaccess serait une opération très coûteuse en ressources,
      annulant partiellement de ce fait l'intérêt de la mise en cache
      (accélérer le traitement des requêtes),
      mod_cache ne se préoccupe pas de savoir s'il a
      l'autorisation de servir une entité mise en cache. En d'autres termes,
      si mod_cache a mis en cache un certain contenu, ce
      dernier sera servi à partir du cache tant qu'il ne sera pas arrivé à
      expiration.
    

      
    Si par exemple, votre configuration autorise l'accès à une ressource
      en fonction de l'adresse IP, vous devez vous assurer que ce contenu n'est
      pas mis en cache. Ceci est possible en utilisant la directive
      CacheDisable, ou le module
      mod_expires. Livré à lui-même,
      mod_cache - pratiquement comme un mandataire inverse -
      mettrait en cache le contenu lors de son service, et le servirait ensuite
      à tout client, vers n'importe quelle adresse IP.
    

      
    Lorsque la directive CacheQuickHandler est définie à
      Off, toutes les phases du traitement de la requête
      sont exécutées et le modèle de sécurité reste le même.
    

    

    
    Piratages locaux
    
      

      
    Etant donné que les requêtes des utilisateurs finaux peuvent être
      servies depuis le cache, ce dernier est une cible potentielle pour ceux
      qui veulent défigurer un contenu ou interférer avec lui. Il est important
      de garder à l'esprit que l'utilisateur sous lequel tourne
      httpd doit
      toujours avoir l'accès en écriture dans le cache. Ceci est en contraste
      total avec la recommandation usuelle d'interdire à l'utilisateur sous
      lequel tourne Apache
      l'accès en écriture à tout contenu.
    

      
    Si l'utilisateur sous lequel tourne Apache est compromis,
      par exemple à cause d'une
      faille de sécurité dans un processus CGI, il est possible que le cache
      fasse l'objet d'une attaque. Il est relativement aisé d'insérer ou de
      modifier une entité dans le cache en utilisant le module
      mod_cache_disk.
    

      
    Cela représente un risque relativement élévé par rapport aux autres
      types d'attaques qu'il est possible de mener sous l'utilisateur apache.
      Si vous utilisez mod_cache_disk, vous devez garder ceci
      à l'esprit : effectuez toujours les mises à jour de
      httpdquand des
      correctifs de sécurité sont annoncés et exécutez les processus CGI sous
      un utilisateur autre qu'apache en utilisant
      suEXEC dans la mesure du possible.
    

    

    
    Empoisonnement du cache (Cache Poisoning)
    
      

      
    Si vous utilisez httpd comme serveur mandataire avec mise en cache,
      vous vous exposez aussi à un éventuel "Empoisonnement du
      cache" (Cache poisoning). L'empoisonnement du cache est un terme général
      pour désigner les attaques au cours desquelles l'attaquant fait en sorte
      que le serveur mandataire renvoie à un contenu incorrect (et souvent
      indésirable) suite à en provenance du serveur d'arrière-plan.
      
    

      
    Par exemple, si les serveur DNS qu'utilise votre système où tourne
      httpd sont vulnérables à l'empoisonnement du cache des DNS, un attaquant
      pourra contrôler vers où httpd se connecte lorsqu'il demande un contenu
      depuis le serveur d'origine.
      Un autre exemple est constitué par les attaques ainsi nommées
      "Dissimulation de requêtes HTTP" (HTTP request-smuggling).
    

      
    Ce document n'est pas le bon endroit pour une discussion approfondie
      à propos de la Dissimulation de requêtes HTTP (utilisez plutôt votre
      moteur de recherche favori); il est cependant important de savoir qu'il
      est possible d'élaborer une série de requêtes, et d'exploiter une
      vulnérabilité d'un serveur web d'origine de telle façon que l'attaquant
      puisse contrôler entièrement le contenu renvoyé par le mandataire.
    
    

    
    Déni de Service / Cachebusting
    
      

      
    Le mécanisme utilisé via l'en-tête Vary permet de mettre en
      cache simultanément plusieurs variantes d'une ressource avec la
      même URL. Le cache sélectionne la variante correcte à envoyer au
      client en fonction des valeurs d'en-tête fournies par ce dernier.
      Ce mécanisme peut devenir un problème lorsqu'on tente d'appliquer
      le mécanisme des variantes à un en-tête connu pour pouvoir
      posséder un grand nombre de valeurs
      possibles en utilisation normal, comme par exemple l'en-tête
      User-Agent. En fonction de la popularité du site web,
      des milliers ou même des millions d'entrées de cache dupliquées
      peuvent être créées pour la même URL, submergeant les autres
      entrées du cache.
    
      
      
    Dans d'autres cas, il peut être nécessaire de modifier l'URL
      d'une ressource particulière à chaque requête, en général en lui
      ajoutant une chaîne "cachebuster". Si ce contenu est déclaré comme
      pouvant être mis en cache par un serveur avec une durée de
      fraîcheur significative, ces entrées peuvent submerger les entrées
      légitimes du cache. Alors que mod_cache fournit
      une directive CacheIgnoreURLSessionIdentifiers,
      cette dernière doit être utilisée avec prudence pour s'assurer que
      les caches du navigateur ou du mandataire le plus proche
      (downstream proxy) ne sont pas victimes du même problème de Déni de
      service.

    Bu sözlük, genelinde HTML sayfa sunumuna, özelinde Apache HTTP Sunucusuna
      özgü ortak terminolojinin bir kısmını içerir. Her kavram ile ilgili daha
      ayrıntılı bilgi bağlarla sağlanmıştır.
    
  
    

    top
    

    

    Tanımlar
    

  
    
    
    Algoritma
    

    
    Bir sorunu sonlu sayıda adımda çözümlemek için uygulanan kurallar
      kümesi veya anlam belirsizliği içermeyen bir formül. Şifreleme için
      kullanılan algoritmalara şifre denir.
    
    

    
    Aktarım Katmanı Güvenliği
    
    
    İngilizcesi: Transport Layer Security (TLS)
    
    
    TCP/IP ağları üzerinden genel iletişimin kimlik doğrulamalı ve şifreli
      yapılabilmesi için SSL’nin ardılı olarak Genel Ağ Mühendisliği Görev Gücü
      (IETF) tarafından oluşturulmuş protokol. TLS’nin 1. sürümü ile SSL’in 3.
      sürümü hemen hemen aynıdır.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Alt istek
    
    
    Diğer dosya sistemlerini veya URL yollarını kısmen veya tamamen
      değerlendiren modüller için sunucuda bir alt istek API'si mevcuttur. Bu
      API'nin olası müşterileri için
      DirectoryIndex,
      mod_autoindex ve mod_include örnek
      verilebilir.
    
    

    
    Anahtar Parolası
    
    
    Özel anahtar dosyalarını yetkisiz kişilerden koruyan sözcük veya
      cümle. Genellikle sadece şifreler
      için kullanılan gizli şifreleme/şifre çözme anahtarını korur.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Apache Eklenti
      Aracı (apxs)
    
    
    İngilizcesi: APache eXtension Tool - apxs
    
    
    Modül kaynak kodlarının devinen
      paylaşımlı nesneler (DSO) halinde
      derlenmesine ve Apache Sunucusu içinde kurulmasına yardım eden bir Perl
      betiği.
    Daha ayrıntılı bilgi için apxs kılavuz
      sayfasına bakınız.
    
    

    
    Apache Taşınabilir Arayüzü (APR)
    
    
    İngilizcesi: Apache Portable Runtime - APR
    
    
    Sunucu ile işletim sistemi arasındaki temel arayüzleri oluşturan
      kütüphaneler kümesine verilen ad. APR, Apache HTTP Sunucusuna paralel
      bağımsız bir proje olarak geliştirilmektedir.
    
      Bakınız: Apache Taşınabilir Arayüzü
      Projesi
    
    

    
    Bağlam
    
    
    Yapılandırma dosyalarında
      sadece belli türdeki yönergelerin
      bulunmasına izin verilen bir bölge.
    
      Bakınız: Apache Yönergelerini
      Açıklamak için Kullanılan Terimler
    
    

    
    Bakışımlı Şifreleme Tekniği
    
    
    Şifreleme ve şifre çözme için tek bir anahtarın kullanıldığı
      bir şifreleme tekniği.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Başlık
    
    
    Bir HTTP isteğinin parçası olarak,
      gönderilen yanıtta asıl içerikten önce yer alan ve içerik hakkında
      mecazlar içeren veri.
    
    

    
    CONNECT
    
    
    Ham veri kanallarını HTTP üzerinden yönlendirmek için kullanılan bir HTTP yöntemi. SSL protokolü gibi diğer protokolleri sarmalamakta kullanılabilir.
    
    

    
    Devingen
      Paylaşımlı Nesne (DSO)
    
    
    İngilizcesi: Dynamic Shared Object (DSO)
    
    
    İstek halinde yüklenebilen, Apache httpd
      çalıştırılabilir dosyasından ayrı olarak derlenmiş modüllerin ortak adı.
    
      Bakınız: Devingen Paylaşımlı Nesne Desteği
    
    

    
    Düz Metin
    
    
    Şifrelenmemiş metin.
    

    
    Düzenli İfade
      (Regex)
    
    
    Metin içinde bir şablon tanımlama yolu. Örneğin, “A harfi ile
      başlayan bütün sözcükler” veya “10 rakamlı telefon numaraları” ya da
      “Baş harfi Z olmayan ve iki virgül içeren cümleler” gibi. Düzenli
      ifadeler, Apache’de belli özniteliklere uygun dosya veya özkaynakları
      toplamak için esnek bir yol sağlamasından ötürü oldukça yararlıdır.
      Örneğin, “resimler” dizini altındaki dosyalardan .gif ve .jpg uzantılı
      olanları toplamak için “/resimler/.*(jpg|gif)$” düzenli
      ifadesi yazılabilir. Dizgileri değiştirmek için düzenli ifadelerin
      kullanıldığı yerlerde, eşleşen (parantezlerin içinde) gruplanmış
      parçalara başvurmak için $1 ... $9 özel değişkenleri kullanılır. $0 özel
      değişkeni eşleşen ifadenin tamamına karşılık gelir. Bir dizgi içinde $
      işaretini kendisi olarak kullanmak isterseniz önüne bir \ imi
      koymalısınız. Geçmişe uyumluluk adına bazı yerlerde $0 yerine &
      değişkeni kullanılabilir. Ancak 2.3.6 sürümünden beri bu artık mümkün
      değildir. Apache, PCRE kütüphanesi ile
      sağlanan Perl uyumlu düzenli ifadeleri kullanır. PCRE düzenli
      ifadelerinin sözdizimi ile ilgili ayrıntılı bilgiyi Wikipedia'da bulabilirsiniz.
    
    

    
    Erişim Denetimi
    
    
    
    Ağ bölgelerine erişimin kısıtlanması. Apache bağlamında normal
      olarak belli URL’lere erişimi kısıtlamak şeklinde
      uygulanır.
     Bakınız:  Kimlik Doğrulama,
      Yetkilendirme ve Erişim Denetimi
    
    

    
    Eylemci
    
    
    Bir dosya istendiğinde uygulanacak eylemi Apache içinde gerçekleştiren
      nesne. Genellikle dosyalar, dosya türüne bağlı dolaylı eylemcilere
      sahiptir. Normalde tüm dosyalar sunucu tarafından sıradan birer dosya
      olarak işleme sokulduğu halde bazı belli dosyalar diğerlerinden ayrı
      ele alınır. Örneğin, cgi-script eylemcisi dosyaları
      CGI’ler tarafından işlenebilir hale
      getirmek üzere işleme sokar.
    
      Bakınız: Apache Eylemcilerinin Kullanımı
    
    

    
    Genel Anahtar
    
    
    Genel Anahtarlı
      Şifreleme Tekniğinde, sahibinin yaptığı imzaları çözmeye ve
      sahibine gönderilen iletileri şifrelemeye yarayan genel erişime açık
      anahtar.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Genel Anahtarlı Şifreleme Tekniği
    
    
    Şifreleme ve şifre çözme için iki ayrı anahtarın kullanıldığı
      bakışımsız şifreleme sistemlerinin konusu veya uygulaması. Bu amaçla
      kullanılan anahtarlar bir anahtar çiftinden oluşur. Genel Anahtarlı
      Şifrelemeye Bakışımsız Şifreleme de denir.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Gizli Anahtar
    
    
    Genel Anahtarlı
      Şifreleme Tekniğinde, giden iletileri imzalamak ve gelen
      iletilerin şifrelerini çözmek amacıyla kullanılan gizli anahtar.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Güvenli Hiper Metin Aktarım Protokolü
      (HTTPS)
    
    
    İngilizcesi: The HyperText Transfer Protocol (Secure), (HTTPS)
    
    
    Güvenli Hiper Metin Aktarım Protokolü, Genel Ağ’da kullanılan standart
      şifreli iletişim mekanizmasıdır. Aslında HTTP protokolünün SSL üzerinden gerçekleştirilmesinden başka bir
      şey değildir.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Güvenli Soket Katmanı
    
    
    İngilizcesi: Secure Sockets Layer (SSL)
    
    
    TCP/IP ağları üzerinden genel iletişimin kimlik doğrulamalı ve şifreli
      yapılabilmesi için Netscape Communications Corporation tarafından
      oluşturulmuş bir protokol. Günümüzde en çok HTTPS, yani SSL
      üzerinden Hiper Metin Aktarım Protokolü şeklinde kullanılmaktadır.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Hiper Metin Aktarım Protokolü
      (HTTP)
    
    
    İngilizcesi: HyperText Transfer Protocol (HTTP)
    
    
    Genel Ağ’da kullanılan standart aktarım protokollerinden biri.

      tanımlanmış protokolün HTTP/1.1 olarak bilinen 1.1 sürümünü gerçekler.
    
    

    
    .htaccess
    
    
    Belge dosyaları ağacı içine yerleştirilen bir yapılandırma dosyası olup yerleştiği
      dizine ve o dizinin alt dizinlerine yapılandırma yönergeleri
      uygulanmasını sağlar. İsmine rağmen böyle bir dosyanın içerebileceği
      yönergeler erişim denetleme yönergeleri ile sınırlı değildir; hemen
      her tür yönergeyi içerebilir.
    
      Bakınız: Yapılandırma Dosyaları
    
    

    
    httpd.conf

      dosyası.  Dosya sistemindeki öntanımlı yeri
      /usr/local/apache2/conf/httpd.conf olup derleme
      sırasındaki yapılandırmayla veya çalışma anındaki yapılandırmayla
      başka bir yer belirtilebilir.
    
      Bakınız: Yapılandırma Dosyaları
    
    

    
    İhracat Engelli
    
    
    İngilizcesi: Export-Crippled
    
    
    Amerika Birleşik Devletlerinin İhracat Yönetim Düzenlemelerine (EAR)
      uymak için şifreleme yoluyla sakatlanmış yazılım. İhracat engelli olması
      için şifrelenmiş yazılımları birer şifreli metin haline getiren şifre
      anahtarları küçük boyutlu olduğundan şifreleme zor
      kullanılarak kırılabilir.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    İleti Özeti
    
    
    İngilizcesi: Message Digest

    Karşı Vekil
    
    
    İstemciye kendini asıl sunucu imiş gibi gösteren bir
      vekil sunucu. Güvenlik, yük dengelemesi
      gibi sebeplerle asıl sunucuyu istemcilerden gizlemek için yararlıdır.
    
    

    
    Kimlik Doğrulama
    
    
    Sunucu, istemci veya kullanıcı gibi bir ağ öğesinin kimliğinin
      olumlanması.
    Bakınız: Kimlik Doğrulama,
      Yetkilendirme ve Erişim Denetimi
    
    

    
    MIME türü
    
    
    Aktarılan belgenin çeşidini betimlemenin bir yolu. MIME, Türkçe’ye
      ‘Çok Amaçlı Genel Ağ Posta Eklentileri’ olarak çevrilebilecek olan
      "Multipurpose Internet Mail Extensions" sözcüklerinden türetilmiş bir
      kısaltmadır. MIME türleri bir bölü çizgisi ile ayrılmış bir ana ve bir
      alt belge türünün birleşiminden oluşur. text/html,
      image/gif ve application/octet-stream örnek
      olarak verilebilir. HTTP protokolünde MIME türleri
      Content-Type başlığında
      aktarılır.
    Bakınız: mod_mime
    
    

    
    Modül
    
    
    Bir programın bağımsız parçalarından her biri. Apache işlevselliğinin
      çoğu yapılandırmaya dahil edilip edilmeyeceğine kullanıcı tarafından
      karar verilebilen modüllerden oluşur. Apache httpd
      çalıştırılabiliri içinde derlenmiş modüllere durağan modüller
      adı verilirken ayrı bir yerde saklanan ve çalışma anında isteğe bağlı
      olarak yüklenebilen modüllere devingen modüller veya
      DSO’lar denir. Yapılandırmaya öntanımlı
      olarak dahil edilen modüllere temel modüller denir. Apache
      için kullanılabilecek modüllerin çoğu Apache HTTP Sunucusunun
      tar paketi içinde dağıtılmaz; bunlara
      üçüncü parti modüller denir.
    
      Bakınız: Modül Dizini
    
    

    
    OpenSSL
    
    
    SSL/TLS için açık kaynak kodlu araç kiti.

    İşletim sistemi kabuğu tarafından yönetilen ve programlar arasında
      bilgi alışverişi amacıyla kullanılan isimli değişkenler. Ayrıca,
      Apache de ortam değişkenleri olarak tanımlanabilecek dahili değişkenler
      içerir fakat bunlar kabuk ortamında değil dahili Apache yapıları içinde
      saklanır.
    
      Bakınız: Apache Ortam Değişkenleri
    
    

    
    Oturum
    
    
    Bir iletişimin bağlamsal bilgileri.
    

    
    Özet
    
    
    Uzunluğu değişebilen bir dizgenin belli bir durumuna ilişkin sabit
      uzunlukta bir dizge üretmek için kullanılan geri dönüşümsüz bir
      algoritma. Algoritmaya girdi olan farklı uzunluktaki dizgeler (özet
      işlevine bağlı olarak) aynı uzunlukta farklı özetler üretir.
    
    

    
    Sanal Konaklık
    
    
    Tek bir Apache sunucusundan çok sayıda site sunulması. IP tabanlı
      sanal konaklıkta siteler birbirlerinden IP adreslerine göre
      ayrılırken, isim tabanlı sanal konaklıkta siteler aynı IP
      adresinden kendi isimleriyle sunulabilirler.
    
      Bakınız: Apache Sanal Konak Belgeleri
    
    

    
    Sayısal İmza
    
    
    Bir sertifikayı veya bir dosyayı doğrulamakta kullanılan şifreli bir
      metin. Bir imza Sertifika
      Makamı tarafından bir sertifikaya gömülü olan
      genel anahtardan bir özet üretilerek oluşturulur. İmza şifresi
      sadece sertifika sahibi ağ öğesinin kimliğini doğrulayacak
      SM’nin genel anahtarı kullanılarak çözülebilir.
    
      Bakınız: SSL/TLS Şifrelemesi
    
    

    
    Sertifika
    
    
    Sunucu, istemci gibi ağ öğelerinin kimliğini kanıtlamakta kullanılan
      bir veri kaydı. Bir sertifika, sertifika sahibi (buna sertifikanın
      konusu da denir), sertifikayı imzalayan Sertifika Makamı (SM) (buna
      sertifika yayıncısı da denir), sertifika sahibinin genel anahtarı ve SM tarafından üretilen imza

    Dieses Dokument beschreibt einige der wichtigsten Änderungen
     des Apache HTTP Servers 2.0 gegenüber der Version 1.3.
    

    


    top
    

    

    Core-Erweiterungen
    
    

    
    
      
    Unix-Threading
    

      
    Auf Unix-Systemen mit Unterstützung für
      POSIX-Threads, kann der Apache httpd jetzt in einem Multi-Process,
      Multi-Threaded Hybrid-Mode gestartet werden. Dies verbessert die
      Skalierfähigkeit für viele, jedoch nicht unbedingt alle
      Konfigurationen.
    

      
    Neues Build-System
    

      
    Das Build-System wurde komplett auf der Basis von
      autoconf und libtool neu geschrieben.
      Dadurch wird das Konfigurationssystem des Apache httpd dem vieler
      anderer Packages ähnlicher.
    

      
    Multi-Protokoll-Unterstützung
    

      
    Der Apache HTTP Server stellt jetzt die notwendigen
      Grundfunktionalitäten bereit, um mehrere Protokolle
      unterstützen und verarbeiten zu können.
      mod_echo wurde hierfür als Beispiel
      geschrieben.
    

      
    Bessere Unterstützung von
      Nicht-Unix-Plattformen
    

      
    Der Apache HTTP Server 2.0 ist schneller und stabiler auf
      Nicht-Unix-Plattformen wie BeOS, OS/2 und Windows. Mit der
      Einführung von Plattform-spezifischen Multi-Processing Modulen (MPMs) und der Apache
      Portable Runtime (APR), sind diese Plattformen jetzt in ihrem
      nativen API implementiert, wodurch die Verwendung der häufig
      fehlerbehafteten und schlecht funktionierenden
      POSIX-Emulation-Layer vermieden wird.
    

      
    Neues Apache-httpd API
    

      
    Das API für Module hat sich in 2.0 stark verändert.
      Die meisten der Sortierungs-/Prioritätsprobleme von Modulen bei
      1.3 sollten nun verschwunden sein. In 2.0 wird hiervon vieles
      automatisch durchgeführt. Die Modulsortierung wird jetzt
      über einen pre-hook vorgenommen, um mehr Flexibilität
      zu bieten. Außerdem wurden neue API-Calls hinzugefügt,
      die zusätzliche Modulfähigkeiten zur Verfügung stellen,
      ohne den Kern des Apache HTTP Servers anpassen zu müssen.
    

      
    IPv6-Unterstützung
    

      
    Auf Systemen, bei denen die zugrundeliegende Apache Portable
      Runtime-Bibliothek IPv6 unterstützt, bekommt der Apache httpd
      standarmäßig IPv6 Listening Sockets. Zusätzlich
      unterstützen die Konfigurationsanweisungen Listen, NameVirtualHost und VirtualHost numerische IPv6-Adressangaben
      (z.B., "Listen [2001:db8::1]:8080").
    

      
    Filterung
    

      
    Apache-httpd-Module können jetzt als Filter entwickelt
      und zur Filterung des rein- und rausgehenden Datenstroms des
      Servers eingesetzt werden. Hierdurch kann beispielsweise die
      Ausgabe von CGI-Skripten durch den INCLUDES-Filter
      von mod_include bearbeitet werden und so
      Server-Side Include-Anweisungen ausgeführt werden. Das Modul
      mod_ext_filter erlaubt externen Programmen als
      Filter zu agieren, in der gleichen Weise wie CGI-Programme als
      Eingabe dienen können.
    

      
    Mehrsprachige Fehlermeldungen
    

      
    Fehlermeldungen die an den Browser rausgehen, stehen jetzt als
      SSI-Dokumente in verschiedenen Sprachen zur Verfügung. Sie
      können bei Bedarf durch den Administrator angepasst werden,
      um ein einheitliches Design zu erreichen.
    

      
    Vereinfachte Konfiguration
    

      
    Viele der verwirrenden Konfigurationsanweisungen wurden vereinfacht.
      Die oft für Verwirrung sorgenden Port- und
      BindAddress-Anweisungen wurden entfernt.
      Ausschließlich die Listen-Anweisung wird nun zum
      Setzen von IP-Addressen und Portnummern benutzt.
      Der Servername und die Portnummer, die für Weiterleitungen und
      zur Erkennung virtueller Server verwendet werden, werden über
      die ServerName-Anweisung
      konfiguriert.
    

      
    Native Windows NT Unicode-Unterstützung
    

      
    Der Apache httpd 2.0 auf Windows NT benutzt jetzt utf-8
      für alle Dateinamen-Kodierungen. Diese werden direkt auf das
      zugrundeliegende Unicode-Dateisystem abgebildet, wodurch
      Mehrsprach-Unterstützung für alle Windows NT-basierten
      Installationen, inklusive Windows 2000 und Windows XP, zur
      Verfügung gestellt wird.  Diese Unterstützung ist
      nicht auf Windows 95, 98 oder ME verfügbar. Hier wird
      weiterhin die jeweils lokale Codepage des Rechners für den
      Zugriff auf das Dateisystem verwendet.
    

      
    Bibliothek für reguläre Ausdrücke aktualisiert
    

      
    Der Apache httpd 2.0 enthält die "Perl Compatible
      Regular Expression Library" (PCRE).
      Bei der Auswertung aller regulären Ausdrücke wird nun
      die leistungsfähigere Syntax von Perl 5 verwendet.
    

    
    
  
    top
    

    

    Modul-Erweiterungen
    
    

    
    
      
    mod_ssl
    

      
    Neues Modul in Apache httpd 2.0. Dieses Modul ist ein
      Interface zu den von OpenSSL bereitgestellten SSL/TLS
      Verschlüsselungs-Protokollen.
    

      
    mod_dav
    

      
    Neues Modul in Apache httpd 2.0. Dieses Modul implementiert
      die HTTP Distributed Authoring and Versioning (DAV) Spezifikation
      zur Erzeugung und Pflege von Web-Inhalten.
    

      
    mod_deflate
    

      
    Neues Modul in Apache httpd 2.0. Dieses Modul erlaubt es
      Browsern, die dies unterstützen, eine Komprimierung des
      Inhaltes vor der Auslieferung anzufordern, um so
      Netzwerk-Bandbreite zu sparen.
    

      
    mod_auth_ldap
    

      
    Neues Modul in Apache httpd 2.0.41. Diese Modul
      ermöglicht die Verwendung einer LDAP-Datenbank zur
      Speicherung von Berechtigungsdaten für die
      HTTP-Basic-Authentication.  Ein Begleitmodul,
      mod_ldap, stellt einen Verbindungs-Pool und die
      Pufferung von Abfrageergebnissen zur Verfügung.
    

      
    mod_auth_digest
    

      
    Zusätzliche Unterstützung für
      prozessübergreifendes Session-Caching mittels Shared-Memory.
      
    

      
    mod_charset_lite
    

      
    Neues Modul in Apache httpd 2.0.
      Dieses experimentelle Modul erlaubt Zeichensatz-Übersetzungen oder
      -Umschlüsselung.
    

      
    mod_file_cache
    

      
    Neues Modul in Apache httpd 2.0. Dieses Modul beinhaltet die
      Funktionalität von mod_mmap_static aus Version
      1.3 des Apache HTTP Server zuzüglich einiger weiterer
      Caching-Funktionen.
    

      
    mod_headers
    

      
    Dieses Modul ist in Apache httpd 2.0 deutlich flexibler
      geworden. Es kann jetzt die von mod_proxy
      genutzten Request-Header manipulieren und es ist möglich
      Response-Header auf Basis von definierten Bedingungen zu
      verändern.
    

      
    mod_proxy
    

      
    Das Proxy Modul wurde komplett neu geschrieben um die
      Möglichkeiten der neuen Filter-Funktionalität
      auszuschöpfen und um einen zuverlässigen Proxy zu haben, der
      den HTTP/1.1-Spezifikationen entspricht. Neue <Proxy>
      -Konfigurationsabschnitte bieten eine besser lesbare (und intern
      schnellere) Kontrolle der vermittelten Seiten.
      Die überladenen <Directory
      "proxy:...">-Konfigurationen werden nicht
      mehr unterstützt. Das Modul ist nun in mehrere Module
      unterteilt, die jeweils ein bestimmtes Übertragungsprotokoll
      unterstützen, wie proxy_connect,
      proxy_ftp und proxy_http.
    

      
    mod_negotiation
    

      
    Die neue Konfigurationsanweisung ForceLanguagePriority
      kann benutzt werden, um sicherzustellen, dass ein Client auf jeden
      Fall ein einzelnes Dokument, anstatt einer NOT ACCEPTABLE- oder
      MULTIPLE CHOICES-Antwort, bekommt. Zusätzlich wurden die
      Negotiation- und Multiview-Algorithmen angepasst um einheitlichere
      Ergebnisse zu liefern. Außerdem wird ein neues
      Type-Map-Format bereitgestellt, das Dokumenteninhalte direkt
      enthalten kann.
    

      
    mod_autoindex
    

      
    Automatisch erzeugte Verzeichnisindizes können zur besseren
      Übersichtlichkeit durch HTML-Tabellen dargestellt werden.
      Genauere Sortierungen, wie Sortierung nach Versionsnummer und
      Wildcard-Filterung des Verzeichnisindizes werden unterstützt.
    

      
    mod_include
    

      
    Neue Anweisungen erlauben es, die Standard Start- und Endtags von
      SSI-Elementen zu ändern. Zudem können die Default-Formate
      für Fehlermeldungen und Zeitangaben nun ebenfalls in der
      Serverkonfiguration vorgenommen werden. Auf die Ergebnisse der
      Auswertung und Gruppierung von regulären Ausdrücken (jetzt
      auf Basis der Perl-Syntax für reguläre Ausdrücke) kann
      über die mod_include Variablen $0
      bis $9 zugegriffen werden.
    

      
    mod_auth_dbm
    

      
    DBM-ähnliche Datenbanken werden jetzt durch die
      Konfigurationsaweisung AuthDBMType
      unterstützt.

    Esse documento descreve algumas das mudanças principais
     entre as versões 1.3 e 2.0 do Servidor HTTP Apache.
    

    


    top
    

    

    Principais Melhorias
    
    

    
    
      
    Threading Unix
    

      
    Em sistemas Unix com suporte a threads POSIX, o Apache pode
      funcionar em modo híbrido multiprocesso e multithread. Não funciona
      em todas configurações, mas melhora a escalabilidade em muitas.
    

      
    Novo Sistema de Compilação
    

      
    O sistema de compilação foi reescrito do zero para utilizar o
      autoconf e o libtool, tornando a
      configuração do sistema Apache mais similar a de outros
      pacotes.
    

      
    Suporte Multi-protocolo
    

      
    O Apache possui agora uma infraestrutura feita para suportar
      múltiplos protocolos. O módulo mod_echo é  um
      exemplo ilustrativo de sua utilização.
    

      
    Suporte Aperfeiçoado para Plataformas Não-Unix
    

      
    O Apache 2.0 está  mais rápido e mais estável em plataformas
      Não-Unix como BeOS, OS/2 e Windows. Com a introdução de módulos
      multi-processamento (MPMs) específicos e a
      Apache Portable Runtime (APR), essas plataformas estão implementando
      as suas APIs nativas, evitando as camadas de emulação POSIX que se
      mostravam lentas e defeituosas.
    

      
    Nova API Apache
    

      
    A API para módulos mudou significativamente na versão 2.0.
      Muitos dos problemas de ordenamento/prioridade da versão
      1.3 foram resolvidos. A versão 2.0 faz o ordenamento automático
      "per-hook" para permitir mais flexibilidade. Novas chamadas foram
      adicionadas para fornecer capacidades adicionais sem a necessidade
      de se aplicar nenhum patch ao servidor Apache principal.
    

      
    Suporte IPv6
    

      
    Em sistemas onde o IPv6 é suportado pela biblioteca de base
      Apache Portable Runtime, o Apache monitora por padrão
      as interfaces IPv6. Em adição as diretrizes  Listen, NameVirtualHost e VirtualHost, suportam correntes (strings) de
      endereços numéricos do tipo IPv6. (ex. "Listen
      [2001:db8::1]:8080").
    

      
    Filtrando
    

      
    Os módulos do Apache agora são feito filtros que
      agem na corrente do conteúdo na medida que este é entregue, tanto
      na entrada quando na saída de dados do servidor. É possível então,
      por exemplo, que o retorno de dados de scripts CGI sejam analisados
      pelas diretrizes do "Server Side Include" usando o filtro INCLUDES do mod_include. O módulo mod_ext_filter, permite que programas externos trabalhem
      como filtros do mesmo modo que aplicações CGI funcionam como
      manipuladores.
    

      
    Respostas de Erro Multi-linguais
    

      
    Mensagens de erro para o navegador agora são fornecidas em
      diversas línguas, usando documentos SSI. Podem ser personalizadas
      pelo administrador que desejar definir seus próprios
      padrões.
    

      
    Configuração Simplificada
    

      
    Muitas diretrizes confusas foram simplificadas. Entre elas,
      Port e BindAddress não existem
      mais; apenas a diretriz Listen
      é usada para direcionar endereços IP; a diretriz ServerName especifica o nome do servidor
      e o número da porta apenas para redirecionamento e reconhecimento

    Suporte Nativo ao Unicode do Windows NT
    

      
    O Apache 2.0 para Windows NT agora usa utf-8 para codificação
      de todos os nomes de arquivos. A tradução para o sistema
      base Unicode, torna possível o suporte multi-lingual para todas
      as instalações da família NT, incluindo o Windows 2000 e Windows XP.
      Esse suporte não se estende ao Windows 95, 98 ou ME, que
      continuam usando o código de páginas da máquina local para o
      acesso ao sistema de arquivos.
    

      
    Biblioteca de Expressões Regulares Atualizada
    

      
    O Apache 2.0 inclui a Biblioteca
      de Expressões Regulares Compatíveis Perl (PCRE).  Todas as
      avaliações de expressões regulares usam a mais poderosa sintaxe
      do Perl 5.

    Melhorias nos Módulos
    
    

    
    
      
    mod_ssl
    

      
    Novo módulo no Apache 2.0. Esse módulo é uma interface
      para os protocolos de codificação SSL/TLS fornecidos pela
      OpenSSL.
    

      
    mod_dav
    

      
    Novo módulo no Apache 2.0. Este módulo implementa as
      especificações de Autoria Distribuída e Versões (Distributed
      Authoring and Versioning - DAV) para HTTP, para a publicação
      e a manutenção de conteúdo da web.
    

      
    mod_deflate
    

      
    Novo módulo no Apache 2.0.  Esse módulo permite o suporte
      a navegadores que solicitam que o conteúdo seja comprimido antes
      da entrega, economizando banda da rede.
    

      
    mod_auth_ldap
    

      
    Novo módulo no Apache 2.0.41. Este módulo permite que 
      bancos de dados LDAP sejam usados para armazenar credenciais
      para Autenticação Básica HTTP. Um módulo que o acompanha mod_ldap, fornece a conciliação de conexões e armazenamento
      de resultados.
    

      
    mod_auth_digest
    

      
    Inclui suporte adicional para armazenamento de sessões
      através de processos que usam memória compartilhada.
    

      
    mod_charset_lite
    

      
    Novo módulo no Apache 2.0. Este modo experimental permite a
      tradução de tabelas de caracteres ou re-codificação.
    

      
    mod_file_cache
    

      
    Novo módulo no Apache 2.0. Esse módulo inclui a funcionalidade
      do mod_mmap_static do Apache 1.3, além de disponibilizar
      outras possibilidades de armazenamento.
    

      
    mod_headers
    

      
    Este módulo está muito mais flexível no Apache 2.0. Pode
      modificar pedidos de cabeçalhos usados pelo mod_proxy, e incondicionalmente pode ajustar cabeçalhos de respostas.
    

      
    mod_proxy
    

      
    O módulo proxy foi totalmente reescrito para levar vantagem
      da nova infraestrutura de filtro e implementar um proxy mais fiel e 
      de acordo com o padrão HTTP/1.1. Além disso, uma nova seção
      de configuração <Proxy> fornece controles mais legíveis (e internamente
      mais rápidos) para sites com proxies; configurações
      sobrecarregadas <Directory "proxy:...">, não
      são suportadas. O módulo agora é dividido em suporte
      de protocolos específicos incluindo proxy_connect,
      proxy_ftp e proxy_http.
    

      
    mod_negotiation
    

      
    A nova diretriz ForceLanguagePriority pode ser usada para assegurar que
      o cliente receba um único documento em todos os casos, ao invés de
      respostas "NOT ACCEPTABLE" ou "MULTIPLE CHOICES". Novos algoritmos
      de negociação e visões múltiplas (MultiViews) foram organizados para
      obter resultados mais consistentes e uma nova forma de tipo de mapa
      (map type) que podem incluir o conteúdo de documentos é fornecido.
    

      
    mod_autoindex
    

      
    As listagens de diretórios automáticas podem ser
      configuradas para usar tabelas HTML para formatações mais limpas
      e permitir controles mais acurados de classificação, incluindo
      ordenação por versão e filtro da lista de
      diretórios através de caracteres-coringa.
    

      
    mod_include
    

      
    Novas diretrizes permitem que as tags padrões start e
      end para elementos SSI, possam ser alteradas e permitir que
      as configurações de formatos de erro e hora sejam incluídos no
      arquivo de configuração principal, ao invés de serem adicionadas
      ao documento SSI. Resultados de análises de expressões regulares
      e agrupamento (baseadas na sintaxe de expressões regulares do Perl)
      podem ser obtidas usando as variáveis do módulo mod_include, de $0 a $9.
    

      
    mod_auth_dbm
    

      
    Agora suporta múltiplos tipos de banco de dados similares ao DBM,
      usando a diretriz 
	  AuthDBMType
      .

    Les directives des fichiers de configuration peuvent s'appliquer
au serveur dans son ensemble, ou seulement à des répertoires, fichiers, hôtes,
ou URLs particuliers.  Ce document décrit comment utiliser les conteneurs de
sections de configuration ou les fichiers .htaccess pour
modifier la portée des directives de configuration.

    Types de conteneurs de sections de
configuration
    


    Modules ApparentésDirectives Apparentées
    


    Il existe deux grands types de conteneurs.  La plupart des conteneurs sont
évalués pour chaque requête.  Les directives qu'ils contiennent s'appliquent
seulement aux requêtes qui sont concernées par le conteneur.  En revanche,
les conteneurs
<IfDefine>, <IfModule>, et
<IfVersion> sont
évalués seulement au démarrage et au redémarrage du serveur.
Si leurs conditions sont vérifiées au démarrage, les directives qu'ils contiennent
s'appliqueront à toutes les requêtes.  Si leurs conditions ne sont pas vérifiées, les
directives qu'ils contiennent seront ignorées.
    


    Le conteneur <IfDefine>
contient des directives qui ne seront appliquées que si un paramètre
approprié a été défini dans la ligne de commande de httpd.
Par exemple,
avec la configuration suivante, toutes les requêtes seront redirigées vers
un autre site si le serveur est démarré en utilisant la ligne de commande :
httpd -DClosedForNow:
    


    <IfDefine ClosedForNow>
    Redirect "/" "http://otherserver.example.com/"
</IfDefine>
    



    Le conteneur <IfModule>
est similaire; les directives qu'il contient ne s'appliqueront que si
un module particulier est disponible au niveau du serveur.
Le module doit être soit compilé statiquement dans le serveur, soit
dynamiquement et dans ce cas, la ligne LoadModule correspondante doit apparaître
plus haut dans le fichier de configuration.  Ce conteneur ne doit être
utilisé que dans le cas où votre fichier de configuration doit fonctionner
indépendamment de la présence ou de l'absence de certains modules.
Il ne doit pas contenir de directives que vous souhaitez voir s'appliquer
systématiquement, car vous pouvez perdre ainsi de précieux messages d'erreur
à propos de modules manquants.
    


    Dans l'exemple suivant, la directive MimeMagicFile ne s'appliquera que si le
module mod_mime_magic est disponible.
    


    <IfModule mod_mime_magic.c>
    MimeMagicFile "conf/magic"
</IfModule>
    



    Le conteneur
<IfVersion>
est similaire aux conteneurs <IfDefine> et <IfModule>; les directives qu'il contient ne
s'appliqueront que si une version particulière du serveur s'exécute.  Ce
conteneur a été conçu pour une utilisation dans les suites de tests
et les grands réseaux qui doivent prendre en compte différentes versions
et configurations de httpd.
    


    <IfVersion >= 2.4>
    # les directives situées ici ne s'appliquent que si la version 
    
    # est supérieure ou égale à 2.4.0.
</IfVersion>
    



    <IfDefine>,
<IfModule>, et
<IfVersion>
peuvent inverser leur test conditionnel en le faisant précéder d'un "!".
De plus, ces sections peuvent être imbriquées afin de définir des restrictions
plus complexes.

    Système de fichiers,
arborescence du site web et expressions booléennes
    


    Les conteneurs de sections de configuration les plus couramment utilisés
sont ceux qui modifient la configuration de points particuliers du système de
fichiers ou de l'arborescence du site web.  Tout d'abord, il est important de
comprendre la différence entre les deux.  Le système de fichiers est une vue
de vos disques tels qu'ils sont perçus par votre système d'exploitation.
Par exemple, avec une installation par défaut,
Apache httpd est situé dans /usr/local/apache2 pour le système de
fichiers UNIX, ou "c:/Program Files/Apache Group/Apache2" pour
le système de fichiers Windows.  (Notez que des slashes directs doivent
toujours être utilisés comme séparateur de chemin
dans les fichiers de configuration d'Apache httpd, même sous
Windows.)  Quant à
l'arborescence du site web, il s'agit d'une vue de votre site
tel que présenté par le
serveur web et perçue par le client.  Ainsi le chemin /dir/ dans
l'arborescence du site web correspond au chemin
/usr/local/apache2/htdocs/dir/ dans le système de fichiers pour
une installation d'Apache httpd par défaut sous UNIX.
En outre, l'arborescence du site web n'a pas besoin de correspondre en permanence au
système de fichiers, car les pages web peuvent être générées dynamiquement
à partir de bases de données ou d'autres emplacements.
    


    Conteneurs de système de fichiers
    


    Les conteneurs <Directory>
et <Files>,
ainsi que leurs équivalents acceptant les
expressions rationnelles,
appliquent des directives à certaines parties du système de fichiers.
Les directives contenues dans une section <Directory> s'appliquent au répertoire
précisé, ainsi qu'à tous ses sous-répertoires et aux fichiers que ces
derniers contiennent.
Le même effet peut être obtenu en utilisant les fichiers .htaccess.  Par exemple, avec la
configuration suivante, l'indexation sera activée pour le répertoire
/var/web/dir1 et tous ses sous-répertoires.
    


    <Directory "/var/web/dir1">
    Options +Indexes
</Directory>
    



    Les directives contenues dans une section <Files> s'appliquent à tout fichier
avec le nom spécifié, quel que soit le répertoire dans lequel il se trouve.
Ainsi par exemple, les directives de configuration suivantes, si elles sont
placées dans la section principale du fichier de configuration, vont interdire
l'accès à tout fichier nommé private.html quel que soit
l'endroit où il se trouve.
    


    <Files "private.html">
    Require all denied
</Files>
    



    Pour faire référence à des fichiers qui se trouvent en des points
particuliers du système de fichiers, les sections
<Files> et
<Directory>
peuvent être combinées.  Par exemple, la configuration suivante va interdire
l'accès à /var/web/dir1/private.html,
/var/web/dir1/subdir2/private.html,
/var/web/dir1/subdir3/private.html, ainsi que toute instance de
private.html qui se trouve dans l'arborescence
/var/web/dir1/.
    


    <Directory "/var/web/dir1">
    <Files "private.html">
        Require all denied
    </Files>
</Directory>
    




    Conteneurs de l'arborescence du site web
    


    le conteneur <Location>
et son équivalent acceptant les
expressions rationnelles, modifient quant à eux la
configuration de parties de l'arborescence du site web.  Par exemple, la
configuration suivante interdit l'accès à toute URL dont la partie chemin
commence par /private.
En particulier, l'interdiction s'appliquera aux requêtes pour :
http://yoursite.example.com/private,
http://yoursite.example.com/private123, et
http://yoursite.example.com/private/dir/file.html ainsi qu'à
toute requête commençant par la chaîne de caractères /private.
    


    <LocationMatch "^/private">
    Require all denied
</LocationMatch>
    



    Le conteneur <Location>
n'a pas besoin de faire référence à un élément du système de fichiers.
Par exemple, l'exemple suivant montre comment faire référence à une URL
particulière vers un gestionnaire interne du serveur HTTP Apache fourni par le module
mod_status.
Il n'est pas nécessaire de trouver un fichier nommé server-status
dans le système de fichiers.
    


    <Location "/server-status">
    SetHandler server-status
</Location>
    




    Espace web imbriqué
    

    Pour contrôler deux URLs imbriquées, on doit tenir compte de l'ordre
dans lequel certaines sections ou directives sont évaluées. Pour
<Location>, on doit
avoir :
    

    <Location "/foo">
</Location>
<Location "/foo/bar">
</Location>
    


    Les directives <Alias>, quant à elles, sont évaluées vice-versa :
    

    Alias "/foo/bar" "/srv/www/uncommon/bar"
Alias "/foo" "/srv/www/common/foo"
    


    Ceci est aussi vrai pour les directives ProxyPass :
    

    ProxyPass "/special-area" "http://special.example.com" smax=5 max=10
ProxyPass "/" "balancer://mycluster/" stickysession=JSESSIONID|jsessionid nofailover=On
    





    Caractères de remplacement
et expressions rationnelles
    


    Les conteneurs
<Directory>,
<Files>, et
<Location>
peuvent utiliser des caractères de remplacement de style shell comme dans
la fonction fnmatch de la bibliothèque C standard.
Le caractère "*"
correspond à toute séquence de caractères, "?" à un caractère seul,
et "[seq]" à tout caractère contenu dans seq.
Le caractère "/"
ne peut pas faire l'objet d'un remplacement;
il doit être spécifié explicitement.
    


    Si une définition des critères de correspondance
encore plus souple est nécessaire, chaque conteneur
possède son équivalent acceptant les expressions rationnelles : <DirectoryMatch>, <FilesMatch>, et <LocationMatch> acceptent les
expressions rationnelles compatibles Perl
pour définir les critères de correspondance.  Mais voyez plus loin la section
à propos de la combinaison des sections de configuration
pour comprendre comment l'utilisation de
conteneurs avec des expressions rationnelles va modifier la manière
dont les directives sont appliquées.
    


    Un conteneur qui modifie la configuration de tous les
répertoires utilisateurs à l'aide de caractères de remplacement
mais sans utiliser
les expressions rationnelles pourrait ressembler à ceci :
    


    <Directory "/home/*/public_html">
    Options Indexes
</Directory>
    



    Avec les conteneurs utilisant les expressions rationnelles,
on peut interdire l'accès à de nombreux types de fichiers d'images
simultanément :
    

    +<FilesMatch "\.(?i:gif|jpe?g|png)$">
    Require all denied
</FilesMatch>
    



    Les expressions rationnelles contenant des groupes nommés et
des références arrières sont ajoutées à l'environnement avec
leur nom en majuscules. Ceci permet de référencer des éléments de
chemins de fichiers et d'URLs depuis une expression et au sein de modules comme
mod_rewrite.
    


    <DirectoryMatch "^/var/www/combined/(?<SITENAME>[^/]+)">
    Require ldap-group "cn=%{env:MATCH_SITENAME},ou=combined,o=Example"
</DirectoryMatch>
    





    Expressions booléennes
    

    La directive <If>
permet de modifier la configuration en fonction d'une condition qui peut
être définie sous la forme d'une expression booléenne. Dans l'exemple
suivant, l'accès est interdit si l'en-tête HTTP Referer ne commence pas
par "http://www.example.com/".
    

    <If "!(%{HTTP_REFERER} -strmatch 'http://www.example.com/*')">
    Require all denied
</If>
    





    Que faut-il utiliser et quand ?
    


    Choisir entre des conteneurs de système de fichiers et des conteneurs
d'arborescence du site web est vraiment très simple.
Pour appliquer des directives à des objets qui résident dans le système de
fichiers, utilisez toujours un conteneur <Directory> ou <Files>.  Pour appliquer des directives à des objets
qui ne résident pas dans le système de fichiers (comme une page web générée
par une base de données), utilisez un conteneur <Location>.
    


    Il ne faut jamais utiliser un conteneur <Location> pour restreindre l'accès à des
objets du système de fichiers, car plusieurs localisations de
l'arborescence du site web (URLs) peuvent correspondre à la même localisation
du système de fichier, ce qui peut permettre de contourner vos restrictions.
Par exemple, imaginez la configuration suivante :
    


    <Location "/dir/">
    Require all denied
</Location>
    



    Elle fonctionne correctement si la requête appelle
http://yoursite.example.com/dir/.  Mais que va-t-il se passer si
votre système de fichiers est insensible à la casse ?
Votre restriction va pouvoir être tout simplement contournée en envoyant une
requête sur
http://yoursite.example.com/DIR/.  Le conteneur <Directory>, quant à lui, s'appliquera
à tout contenu servi à partir de cette localisation,
sans tenir compte de la manière dont il est appelé.
(Les liens du système de fichiers constituent une exception.
Le même répertoire peut être placé dans plusieurs parties du système de
fichiers en utilisant des liens symboliques.  Le conteneur
<Directory> va suivre le
lien symbolique sans modifier le nom du chemin.  Par conséquent, pour plus de
sécurité, les liens symboliques doivent être désactivés à l'aide de la
directive
Options appropriée.)
    


    Si vous pensez que vous n'êtes pas concerné par ce problème
parceque vous utilisez un système de fichiers sensible à la casse,
gardez à l'esprit qu'il y a de nombreuses autres manières pour faire
correspondre plusieurs localisations de l'arborescence du site web à la même
localisation du système de fichiers.  C'est pourquoi vous devez autant que
possible toujours utiliser les conteneurs de système de fichiers.
Il y a cependant une exception à cette règle.  Placer des restrictions de
configuration dans un conteneur <Location
"/"> est tout à fait sans rique car ce conteneur va s'appliquer à
toutes les requêtes sans tenir compte de l'URL spécifique.
    



    Imbrication des sections
    


    Certains types de sections peuvent être imbriqués : d'une part, on peut
utiliser les sections <Files>
à l'intérieur des sections <Directory>, d'autre part, on peut utiliser les
directives <If> à l'intérieur
des sections <Directory>,
<Location> et <Files> (mais pas à l'intérieur d'une
autre section <If>). Les
valeurs des expressions rationnelles correspondant aux sections nommées se
comportent de manière identique.
    


    Les sections imbriquées sont fusionnées après les sections
non-imbriquées de même type.

    Serveurs virtuels
    


    Le conteneur <VirtualHost>
contient des directives qui s'appliquent à des serveurs virtuels spécifiques.
Ceci s'avère utile pour servir les contenus de plusieurs serveurs virtuels à
partir de la même machine, chacun d'entre eux possédant une configuration
différente.  Pour de plus amples informations, voir la Documentation sur les serveurs virtuels.
    

    top
    

    

    Mandataire
    


    Les conteneurs
<Proxy>
et <ProxyMatch>
appliquent les directives de configuration qu'ils contiennent uniquement aux
sites qui correspondent à l'URL spécifiée et auxquels on a
accédé via le serveur mandataire du module mod_proxy.
Par exemple, la configuration suivante n'autorisera qu'un sous-ensemble de
clients à accéder au site www.example.com en passant par le serveur
mandataire :.
    


    <Proxy "http://www.example.com/*">
    Require host yournetwork.example.com
</Proxy>
    


    top
    

    

    Quelles sont les directives autorisées ?
    


    Pour déterminer quelles sont les directives autorisées pour tel type de
section de configuration, vérifiez le Contexte de la directive.
Tout ce qui est autorisé dans les sections
<Directory>
l'est aussi d'un point de vue syntaxique dans les sections
<DirectoryMatch>,
<Files>,
<FilesMatch>,
<Location>,
<LocationMatch>,
<Proxy>,
et <ProxyMatch>.
Il y a cependant quelques exceptions :
    



    top
    

    

    Comment les sections sont combinées entre elles
    


    Les sections de configuration sont appliquées dans un ordre très particulier.
Il est important de savoir comment cet ordre est défini car il peut avoir
des effets importants sur la manière dont les directives de configuration
sont interprétées.
    

    
    L'ordre dans lequel les sections sont appliquées est :
    

    
      
      
    1.  Les sections <Directory> (à l'exception des
      expressions rationnelles)
      et les fichiers .htaccess sont appliquées simultanément (avec
      la possibilité pour .htaccess, s'il y est autorisé, de
      prévaloir sur
      <Directory>)
      2. 

      
    2. Les sections
      <DirectoryMatch>
      (et <Directory "~">)
      3. 

      
    3. Les sections <Files> et <FilesMatch> sont appliquées
      simultanément
      4. 

      
    4. Les sections
      <Location>
      et <LocationMatch> sont appliquées
      simultanément
      5. 

      
    5. Les directives <If>
      
      6. 
    
    

    
    Quelques remarques importantes :
    
    
      
    
    • Mises à part les sections <Directory>, dans chaque groupe, les sections sont
    traitées selon
    l'ordre dans lequel elles apparaissent dans les fichiers de configuration.
    Par exemple, une requête pour /foo/bar correspondra à
    <Location "/foo/bar"> et <Location
    "/foo"> (dans ce cas le groupe 4) : les deux sections seront
    évaluées mais selon l'ordre dans lequel elles apparaissent dans le fichier
    de configuration..
      • 
    
    • Les sections <Directory> (groupe 1 ci-dessus)
    sont traitées dans l'ordre du répertoire le plus court vers le plus long.
    Par exemple, <Directory "/var/web/dir"> sera
    traitée avant <Directory
    "/var/web/dir/subdir">.
      • 
    
    • Si plusieurs sections <Directory> s'appliquent au même
    répertoire, elles sont traitées selon l'ordre dans lequel elles
    apparaissent dans le fichier de configuration.
      • 
    
    • Les sections de configuration incluses via la directive Include sont traitées comme si elles se
    trouvaient réellement dans le fichier qui les inclut à la position de la
    directive
    Include.
      • 
    
    • Les sections situées à l'intérieur de sections <VirtualHost>
    sont appliquées après les sections correspondantes situées en
    dehors de la définition de l'hôte virtuel, ce qui permet à l'hôte virtuel
    de prévaloir sur la configuration du serveur principal.

    Note technique
    
	Une séquence <Location>/<LocationMatch>
	est réellement traitée juste avant la phase de traduction du nom
	(où Aliases et DocumentRoots
      sont utilisés pour faire correspondre les URLs aux noms de fichiers).
      Les effets de cette séquence disparaissent totalement lorsque
      la traduction est terminée.
	
    


    Interactions entre
modules et sections de configuration
    
    
    Une question se pose souvent après avoir lu comment les sections de
    configuration sont fusionnées : comment et quand les directives de modules
    particuliers comme mod_rewrite sont-elles interprétées ? La
    réponse n'est pas triviale et nécessite un approfondissement. Chaque module
    httpd gère sa propre configuration, et chacune de ses directives dans
    httpd.conf définit un élément de configuration dans un contexte particulier.
    httpd n'exécute pas une commande au moment où elle est lue.
    
    
    A l'exécution, le noyau de httpd parcourt les sections de configuration
    dans l'ordre décrit ci-dessus afin de déterminer lesquelles s'appliquent à
    la requête courante. Lorsqu'une première section s'applique, elle est
    considérée comme la configuration courante pour cette requête. Si une
    section suivante s'applique aussi, chaque module qui possède des directives
    dans chacune de ces sections a la possibilité de fusionner sa configuration
    entre ces deux sections. Il en résulte une troisième configuration et le
    processus de fusion se poursuit jusqu'à ce que toutes les sections de
    configuration aient été évaluées.
    
    
    Après l'étape précédente, le traitement proprement dit de la requête HTTP
    peut commencer : chaque module peut effectuer toute tâche qui lui incombe,
    et pour déterminer de quelle manière dont il doit agir, il peut s'appuyer
    sur le noyau de httpd pour retrouver sa configuration globale issue de la
    fusion précédente.
    
    
    Un exemple permet de mieux visualiser l'ensemble du processus. La
    configuration suivante utilise la directive Header du module
    mod_headers pour définir un en-tête HTTP spécifique. Quelle
    valeur httpd va-t-il affecter à l'en-tête CustomHeaderName pour
    une requête vers /example/index.html ?
    
    
    
    <Directory "/">
    Header set CustomHeaderName one
    <FilesMatch ".*">
        Header set CustomHeaderName three
    </FilesMatch>
</Directory>

<Directory "/example">
    Header set CustomHeaderName two
</Directory>
    

    
      
        
    • Directory "/" s'applique, et une configuration
	initiale est créée qui définit l'en-tête CustomHeaderName
	avec la valeur one.
      • 
        
    • Directory "/example" s'applique, et comme
	mod_headers spécifie dans son code que
	la valeur d'un en-tête doit être écrasée si ce dernier est défini à
	nouveau, une nouvelle configuration est créée qui définit l'en-tête
	CustomHeaderName avec la valeur two.
      • 
        
    • FilesMatch ".*" s'applique, une nouvelle
	opportunité de fusion surgit, et l'en-tête CustomHeaderName
	est défini à la valeur three.
      • 
        
    • Finalement, au cours des étapes suivantes du traitement de la
	requête HTTP, mod_headers sera sollicité, et il se
	basera sur la configuration qui a défini l'en-tête
	CustomHeaderName à la valeur three.
	mod_headers utilise normalement cette configuration pour
	accomplir sa tâche, à savoir définir des en-têtes HTTP. Cela ne veut
	cependant pas dire qu'un module ne peut pas effectuer des actions plus
	complexes comme désactiver des directives car elle ne sont pas
	nécessaires ou obsolètes, etc...
      • 
    
    

    
    Ceci est aussi vrai pour les fichiers .htaccess car ils possèdent la même
    priorité que les sections Directory dans l'ordre de
    fusion. Il faut bien comprendre que les sections de configuration comme
    Directory et FilesMatch ne
    sont pas comparables avec les directives spécifiques de modules comme
    Header ou RewriteRule car elles agissent à des
    niveaux différents.
    
    



    Quelques exemples utiles
    


    Voici un exemple imaginaire qui montre l'ordre de combinaison des sections.
En supposant qu'elles s'appliquent toutes à la requête, les directives de
cet exemple seront appliquées dans l'ordre suivant : A > B > C > D >
E.
    


    <Location "/">
    E
</Location>

<Files "f.html">
    D
</Files>

<VirtualHost *>
   <Directory "/a/b">
        B
   </Directory>
</VirtualHost>

<DirectoryMatch "^.*b$">
    C
</DirectoryMatch>

<Directory "/a/b">
    A
</Directory>
    



    Pour un exemple plus concret, considérez ce qui suit.  Sans tenir compte
de toute restriction d'accès placée dans les sections <Directory>, la section <Location> sera
évaluée en dernier et permettra un accès au serveur sans aucune restriction.
En d'autres termes, l'ordre de la combinaison des sections est important,
soyez donc prudent !
    


    <Location "/">
    Require all granted
</Location>

# Arrghs!  Cette section <Directory> n'aura aucun effet
<Directory "/">
    <RequireAll>
        Require all granted
        Require not host badguy.example.com
    </RequireAll>
</Directory>

Server.

    Main Configuration Files
    
    
    
    Related ModulesRelated Directives
    

    
    Apache HTTP Server is configured by placing directives in plain text
    configuration files. The main configuration file is usually called
    httpd.conf. The location of this file is set at
    compile-time, but may be overridden with the -f
    command line flag. In addition, other configuration files may be
    added using the Include
    directive, and wildcards can be used to include many configuration
    files. Any directive may be placed in any of these configuration
    files. Changes to the main configuration files are only
    recognized by httpd when it is started or restarted.
    

    
    The server also reads a file containing mime document types;
    the filename is set by the TypesConfig directive,
    and is mime.types by default.
    
  
    top
    

    

    Syntax of the Configuration Files
    
    

    
    httpd configuration files contain one directive per line.
    The backslash "\" may be used as the last character on a line
    to indicate that the directive continues onto the next line.
    There must be no other characters or white space between the
    backslash and the end of the line.
    

    
    Arguments to directives are separated by whitespace. If an 
    argument contains spaces, you must enclose that argument in quotes.
    

    
    Directives in the configuration files are case-insensitive,
    but arguments to directives are often case sensitive. Lines
    that begin with the hash character "#" are considered
    comments, and are ignored. Comments may not be
    included on the same line as a configuration directive. 
    White space occurring before a directive is ignored, so
    you may indent directives for clarity. Blank lines are also ignored.
    

    
    The values of variables defined with the Define of or shell environment variables can
    be used in configuration file lines using the syntax ${VAR}.
    If "VAR" is the name of a valid variable, the value of that variable is
    substituted into that spot in the configuration file line, and processing
    continues as if that text were found directly in the configuration file.
    Variables defined with Define take
    precedence over shell environment variables.
    If the "VAR" variable is not found, the characters ${VAR}
    are left unchanged, and a warning is logged.
    Variable names may not contain colon ":" characters, to avoid clashes with
    RewriteMap's syntax.
    

    
    Only shell environment variables defined before the server is started
    can be used in expansions. Environment variables defined in the
    configuration file itself, for example with SetEnv, take effect too late to be used for
    expansions in the configuration file.
    

    
    The maximum length of a line in normal configuration files, after
    variable substitution and joining any continued lines, is approximately
    16 MiB. In .htaccess files, the
    maximum length is 8190 characters.
    

    
    You can check your configuration files for syntax errors
    without starting the server by using apachectl
    configtest or the -t command line
    option.
    

    
    You can use mod_info's -DDUMP_CONFIG to
    dump the configuration with all included files and environment
    variables resolved and all comments and non-matching
    <IfDefine> and
    <IfModule> sections
    removed. However, the output does not reflect the merging or overriding
    that may happen for repeated directives.

    Modules
    
    

    
    Related ModulesRelated Directives
    

    
    httpd is a modular server. This implies that only the most
    basic functionality is included in the core server. Extended
    features are available through modules which can be loaded
    into httpd. By default, a base set of modules is
    included in the server at compile-time. If the server is
    compiled to use dynamically loaded
    modules, then modules can be compiled separately and added at
    any time using the LoadModule
    directive.
    Otherwise, httpd must be recompiled to add or remove modules.
    Configuration directives may be included conditional on a
    presence of a particular module by enclosing them in an <IfModule> block. However,
    <IfModule> blocks are not
    required, and in some cases may mask the fact that you're missing an
    important module.
    

    
    To see which modules are currently compiled into the server,
    you can use the -l command line option. You can also
    see what modules are loaded dynamically using the -M
    command line option.
    
  
    top
    

    

    Scope of Directives
    
    

    
    Related ModulesRelated Directives
    

    
    Directives placed in the main configuration files apply to
    the entire server. If you wish to change the configuration for
    only a part of the server, you can scope your directives by
    placing them in <Directory>, <DirectoryMatch>, <Files>, <FilesMatch>, <Location>, and <LocationMatch>
    sections. These sections limit the application of the
    directives which they enclose to particular filesystem
    locations or URLs. They can also be nested, allowing for very
    fine grained configuration.
    

    
    httpd has the capability to serve many different websites
    simultaneously. This is called Virtual
    Hosting. Directives can also be scoped by placing them
    inside <VirtualHost>
    sections, so that they will only apply to requests for a
    particular website.
    

    
    Although most directives can be placed in any of these
    sections, some directives do not make sense in some contexts.
    For example, directives controlling process creation can only
    be placed in the main server context. To find which directives
    can be placed in which sections, check the Context of the
    directive. For further information, we provide details on How Directory, Location and Files sections
    work.
    
  
    top
    

    

    .htaccess Files
    
    

    
    Related ModulesRelated Directives
    

    
    httpd allows for decentralized management of configuration
    via special files placed inside the web tree. The special files
    are usually called .htaccess, but any name can be
    specified in the AccessFileName
    directive. Directives placed in .htaccess files
    apply to the directory where you place the file, and all
    sub-directories. The .htaccess files follow the
    same syntax as the main configuration files. Since
    .htaccess files are read on every request, changes
    made in these files take immediate effect.
    

    
    To find which directives can be placed in
    .htaccess files, check the Context of the
    directive. The server administrator further controls what
    directives may be placed in .htaccess files by
    configuring the AllowOverride
    directive in the main configuration files.
    

    
    For more information on .htaccess files, see
    the .htaccess tutorial.

     2.0 and 2.2 versions of the Apache HTTP Server. For new features since
     version 1.3, see the 2.0 new features
     document.
    

    


    top
    

    

    Core Enhancements
    
    
    
    

      
    Authn/Authz
    
      
    The bundled authentication and authorization modules have
          been refactored.  The new mod_authn_alias(already removed from 2.3/2.4)
          module can greatly simplify certain authentication configurations.
          See module name changes, and
          the developer changes for more
          information about how these changes affects users and module
          writers.
    

      
    Caching
    
      
    mod_cache, mod_cache_disk, and
          mod_mem_cache(already removed from 2.3/2.4) have undergone a lot of changes, and
          are now considered production-quality. htcacheclean
          has been introduced to clean up mod_cache_disk
          setups.
    

      
    Configuration
    
      
    The default configuration layout has been simplified and
          modularised. Configuration snippets which can be used to
          enable commonly-used features are now bundled with Apache, and
          can be easily added to the main server config.
    

      
    Graceful stop
    
      
    The prefork, worker and
          event  MPMs now allow httpd
          to be shutdown gracefully via the
          graceful-stop
          signal. The GracefulShutdownTimeout directive
          has been added to specify an optional timeout, after which
          httpd will terminate regardless of the status
          of any requests being served.
    

      
    Proxying
    
      
    The new mod_proxy_balancer module provides
          load balancing services for mod_proxy.
          The new mod_proxy_ajp module adds support for the
          Apache JServ Protocol version 1.3 used by
          Apache Tomcat.
    

      
    Regular Expression Library Updated
    
      
    Version 5.0 of the
          Perl Compatible Regular Expression
          Library (PCRE) is now included.  httpd can be
          configured to use a system installation of PCRE by passing the
          --with-pcre flag to configure.
    

      
    Smart Filtering
    
      
    mod_filter introduces dynamic configuration
          to the output filter chain.  It enables filters to be conditionally
          inserted, based on any Request or Response header or environment
          variable, and dispenses with the more problematic dependencies and
          ordering problems in the 2.0 architecture.
    

      
    Large File Support
    
      
    httpd is now built with support for files larger
          than 2GB on modern 32-bit Unix systems.  Support for handling
          >2GB request bodies has also been added.
    

      
    Event MPM
    
      
    The event MPM uses a separate thread to handle
          Keep Alive requests and accepting connections.  Keep Alive requests
          have traditionally required httpd to dedicate a worker to handle it.
          This dedicated worker could not be used again until the Keep Alive
          timeout was reached.
    

      
    SQL Database Support
    
      
    mod_dbd, together with the apr_dbd
          framework, brings direct SQL support to modules that need it.
          Supports connection pooling in threaded MPMs.
    

    
    
  
    top
    

    

    Module Enhancements
    
    
    
    
      
    Authn/Authz
    
      
    Modules in the aaa directory have been renamed and offer
          better support for digest authentication.  For example,
          mod_auth is now split into
          mod_auth_basic and
          mod_authn_file; mod_auth_dbm is now
          called mod_authn_dbm; mod_access has
          been renamed mod_authz_host.  There is also a new
          mod_authn_alias(already removed from 2.3/2.4) module for simplifying
          certain authentication configurations.
      
    

      
    mod_authnz_ldap
    
      
    This module is a port of the 2.0
          mod_auth_ldap module to the 2.2 Authn/Authz
          framework.  New features include using LDAP attribute values and
          complicated search filters in the
          Require directive.
    

      
    mod_authz_owner
    
      
    A new module that authorizes access to files based
          on the owner of the file on the file system
    

      
    mod_version
    
      
    A new module that allows configuration blocks to be enabled based on the
          version number of the running server.
    

      
    mod_info
    
      
    Added a new ?config argument which will show
          the configuration directives as parsed by Apache, including
          their file name and line number.  The module also
          shows the order of all request hooks and additional
          build information, similar to httpd -V.
    

      
    mod_ssl
    
      
      
    Added a support for
         RFC 2817, which
         allows connections to upgrade from clear text to TLS encryption.
    

      
    mod_imagemap
    
      
    mod_imap has been renamed to
          mod_imagemap to avoid user confusion.

    Program Enhancements
    
    
    
    
      
    httpd
    
      
    A new command line option -M has been added that
      lists all modules that are loaded based on the current
      configuration. Unlike the -l option, this list
      includes DSOs loaded via mod_so.
    

      
    httxt2dbm
    
      
    A new program used to generate dbm files from text input,
          for use in RewriteMap
          with the dbm map type.

    Module Developer Changes
    
    
    
    
      
    APR 1.0 API
    

      
    Apache 2.2 uses the APR 1.0 API.  All deprecated functions and
          symbols have been removed from APR and
          APR-Util. For details, see the
          APR Website.
    

      
    Authn/Authz
    
      
    The bundled authentication and authorization modules have
          been renamed along the following lines:
          
      
          
    • mod_auth_*  -> Modules that implement an HTTP
          authentication mechanism
      • 
          
    • mod_authn_* -> Modules that provide a backend
          authentication provider
      • 
          
    • mod_authz_* -> Modules that implement
          authorization (or access)
      • 
          
    • mod_authnz_* -> Module that implements both
          authentication & authorization
      • 
          
    
          There is a new authentication backend provider
          scheme which greatly eases the construction of new authentication
          backends.
    

      
    Connection Error Logging
    

      
    A new function, ap_log_cerror has been added to log
          errors that occur with the client's connection.  When logged,
          the message includes the client IP address.
    

      
    Test Configuration Hook Added
    

      
    A new hook, test_config has been added to aid
          modules that want to execute special code only when the user passes
          -t to httpd.
    

      
    Set Threaded MPM's Stacksize
    

      
    A new directive, ThreadStackSize has been added to
          set the stack size on all threaded MPMs.  This is required
          for some third-party modules on platforms with small default
          thread stack size.
    

      
    Protocol handling for output filters
    

      
    In the past, every filter has been responsible for ensuring
          that it generates the correct response headers where it affects
          them.  Filters can now delegate common protocol management to
          mod_filter, using the
          ap_register_output_filter_protocol or
          ap_filter_protocol calls.
    

      
    Monitor hook added
    
      
    Monitor hook enables modules to run regular/scheduled jobs
          in the parent (root) process.
    

      
    Regular expression API changes
    

      
    The pcreposix.h header is no longer available;
      it is replaced by the new ap_regex.h header.  The
      POSIX.2 regex.h implementation exposed by the old
      header is now available under the ap_ namespace
      from ap_regex.h.  Calls to regcomp,
      regexec and so on can be replaced by calls to
      ap_regcomp, ap_regexec.
    

      
    DBD Framework (SQL Database API)
    

      
    With Apache 1.x and 2.0, modules requiring an SQL backend
      had to take responsibility for managing it themselves.  Apart
      from reinventing the wheel, this can be very inefficient, for
      example when several modules each maintain their own connections.
    

      
    Apache 2.1 and later provides the ap_dbd API for
      managing database connections (including optimised strategies
      for threaded and unthreaded MPMs), while APR 1.2 and later provides
      the apr_dbd API for interacting with the database.
    

      
    New modules SHOULD now use these APIs for all SQL database
      operations.  Existing applications SHOULD be upgraded to use it
      where feasible, either transparently or as a recommended option
      to their users.

    Bu belgede Apache HTTP Sunucusunu yapılandırmakta kullanılan dosyalar
açıklanmıştır.

    Ana Yapılandırma Dosyaları
    
    
    
    İlgili Modüllerİlgili Yönergeler
    

    
    Apache HTTP Sunucusu düz metin yapılandırma dosyalarına yönergeler yerleştirilerek yapılandırılır.
    Ana yapılandırma dosyasının ismi normalde httpd.conf’tur.
    Bu dosyanın yeri derleme sırasında belirlenir, ancak çalıştırma
    sırasında -f komut satırı seçeneği ile başka bir yer
    belirtilebilir. Ayrıca, Include
    yönergesi kullanılarak başka yapılandırma dosyaları da eklenebilir
    ve bu dosyaların isimleri belirtilirken dosya ismi şablonları
    kullanılabilir. Bu dosyaların içine de ana yapılandırma dosyasında
    olduğu gibi her türlü yönerge yerleştirilebilir. Ana yapılandırma
    dosyalarındaki değişiklikler httpd tarafından sadece başlatma veya
    yeniden başlatma sırasında etkin kılınır.
    

    
    Sunucu ayrıca MIME belge türlerini içeren bir dosya daha okur;
    dosya ismi öntanımlı olarak mime.types olup TypesConfig yönergesi ile başka bir dosya
    belirtilebilir.
    
  
    top
    

    

    Yapılandırma Dosyalarının Sözdizimi
    
    

    
    httpd yapılandırma dosyalarının her satırında sadece bir yönerge
    bulunur ve bir yönergenin birden fazla satıra yayılması daha iyi
    olacaksa satır katlanabilir; devamı bir alt satırda olan her satırın
    son karakteri “\” (tersbölü) olmalı, satırsonu karakteri ile bu tersbölü
    karakteri arasında başka karakter bulunmamalıdır.
    

    
    Yönergelerdeki değiştirgeler boşluklarla ayrılır. Eğer bir değiştirge
    kendi içinde boşluklar içeriyorsa tırnak içine alınır.
    

    
    Yapılandırma dosyalarındaki yönergelerin isimleri harf büyüklüğüne
    duyarlı olduğu halde argümanları genellikle harf büyüklüğüne duyarlı
    değildir. Diyez (“#”) karakteri ile başlayan satırlar açıklama olarak
    ele alınır ve yok sayılırlar. Yapılandırma yönergesi içeren satırlara
    açıklama yerleştirilemez. Yönerge isminden önce yer alan boşluklar
    yoksayılır; bu özellik, okunabilirliği sağlamak için yönergelerin
    girintilenebilmesi olanağını verir. Ayrıca, boş satırlar da
    yoksayılır.
    


    
    Define ile veya kabuğun ortam
    değişkenleri ile tanımlanmış değişkenlerin değerleri, yapılandırma
    dosyasının satırlarında ${VAR} sözdizimi ile kullanılabilir.
    "VAR" geçerli bir değişkenin adı olduğu takdirde, bu değişkenin değeri
    yapılandırma dosyasının bu noktasında yerine konacak ve orada zaten
    değişken yerine değeri varmış gibi işlem kaldığı yerden devam edecektir.
    Define ile tanımlanmış değişkenler
    kabuğun ortam değişkenlerinden önceliklidir. "VAR" diye bir değişken yoksa
    ${VAR} içindeki karakterler değişmeden kalır ve günlüğe bir
    uyarı çıktılanır. RewriteMap
    sözdizimi ile olası bir karışıklığı önlemek için, değişken isimleri iki
    nokta imini (":") içeremez.
    

    
    Kabuğun ortam değişkenlerinin, sadece, sunucu başlatılmadan önce
    tanımlanmış değerleri kullanılabilir.  Yapılandırma dosyasının kendisinde
    tanımlanmış ortam değişkenleri (örneğin,
    SetEnv ile), yapılandırma
    dosyasındaki işlemlerde çok daha sonra yer alır.
    

    
    Yapılandırma dosyasındaki bir satırın uzunluğu, değişken ikamesi
    yapıldıkta, devam satırları eklenditen sonra en fazla 16MiB olabilir. .htaccess dosyalarında azami uzunluk
    8190 karakterdir.
    

    
    Sunucuyu başlatmadan önce apachectl configtest ile veya
    -t komut satırı seçeneği ile yapılandırma dosyalarınızı
    sözdizimi hatalarına karşı sınayabilirsiniz.
    

    
    Eşleşmeyen <IfDefine>
    ve <IfModule> bölümleri
    kaldırılmış, tüm açıklamalar, çözümlenmiş ortam değişkenleri ve içerilmiş
    tüm dosyalar dahil yapılandırmanın bir dökümünü almak için
    mod_info'nun -DDUMP_CONFIG seçeneğini
    kullanabilirsiniz. Ancak, çıktı yinelenen yönergeler için katıştırılan veya
    geçersiz kılınanları yansıtmayacaktır.

    Modüller
    
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    httpd modüler yapıda bir sunucudur. Bu, çekirdek sunucunun sadece en
    temel işlevselliği içermesi demektir. Ek özellikler, httpd’ye modüller halinde yüklenebilir. Öntanımlı olarak, derleme
    sırasında sunucunun temel bir
    modül kümesi içermesi sağlanır. Eğer sunucu  devingen
    yüklenen modülleri kullanmak üzere yapılandırılarak derlenirse modüller
    ayrı olarak derlenip gerektiği zaman 
    LoadModule yönergesi kullanılarak yüklenebilir. Aksi takdirde,
    ek modülleri yükleyebilmek veya kaldırabilmek için httpd’nin yeniden
    derlenmesi gerekir. Yapılandırma yönergeleri belli bir modülün varlığına
    dayalı olarak bir <IfModule>
    bloku içine alınmak suretiyle sunucuya koşullu olarak eklenebilir. Ancak,
    <IfModule> yönergeleri
    gerekli değildir, önemli bir modülün yokluğu gibi durumlarda
    maskelenebilir.
    

    
    Sunucunun içinde derlenmiş modüllerin listesini görmek için
    -l komut satırı seçeneğini kullanabilirsiniz. Ayrıca,
    -M komut satırı seçeneği ile hangi modüllerin devingen olarak
    yüklendiğini görebilirsiniz.

    Yönergelerin Etki Alanı
    
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    Ana yapılandırma dosyasına yerleştirilen yönergeler sunucunun tamamına
    uygulanır. Yapılandırmanızı sunucunun belli bir parçası için değiştirmek
    isterseniz yönergelerinizi <Directory>, <DirectoryMatch>, <Files>, <FilesMatch>, <Location> ve <LocationMatch> bölümleri içine yerleştirerek etki
    alanlarını değiştirebilirsiniz. Bu bölümler yönergelerin etkilediği
    alanları dosya sistemininin belli yerleri veya belli URL’lerle sınırlar.
    Yerine göre daha hassas ayarlamalar yapmak için bu bölgeler iç içe de
    kullanılabilir.
    

    
    httpd, çok sayıda farklı siteyi aynı anda sunabilecek yetenektedir.
    Buna Sanal Konaklık adı verilir. Yönergelerin etki
    alanları ayrıca <VirtualHost>
    bölümleri içine konarak da değiştirilebilir. Böylece belli bir siteye gelen
    isteklere farklı bir uygulama yapılabilir.
    

    
    Yönergelerin çoğu bu bölümlere yerleştirilebilirse de bazı yönergelerin
    bazı bağlamlarda bir etkisi olmaz. Örneğin, süreç oluşturmayı denetleyen
    yönergeler sadece ana sunucu bağlamına yerleştirilebilir. Hangi yönergenin
    hangi bağlama yerleştirilebileceğini bulmak için yönergenin bağlamına bakınız. Bu konuda daha

    .htaccess Dosyaları
    
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    httpd yapılandırma sorumluluğunu dağıtmak için site ağaçları içine özel
    dosyalar yerleştirilmesine izin verir. Bu özel dosyalar normalde
    .htaccess dosyaları olmakla birlikte AccessFileName yönergesi kullanılarak rasgele bir isim
    belirtilebilir. .htaccess dosyalarına yerleştirilen yönergeler
    sadece dosyanın bulunduğu dizine ve alt dizinlerine uygulanır.
    .htaccess dosyalarında da ana yapılandırma dosyalarında geçerli
    sözdizimi kullanılır. .htaccess dosyaları her istek gelişinde
    yeniden okunduğundan bu dosyalarda yapılan değişiklikler hemen etkisini
    gösterir.
    

    
    .htaccess dosyalarına hangi yönergelerin
    yerleştirilebileceğini bulmak için yönerge bağlamına bakınız.
    Sunucunun yöneticisi .htaccess dosyalarına hangi yönergelerin
    yerleştirilebileceğini ana yapılandırma dosyalarında
    AllowOverride yönergesini kullanarak
    belirleyebilir.

    Bu belgede Çok Süreçlilik Modülü denince ne anlaşıldığı ve bunların
    Apache HTTP Sunucusu tarafından nasıl kullanıldıkları açıklanmıştır.
    

    


    top
    

    

    Giriş
    

    
    Apache HTTP Sunucusu çok çeşitli platformlar üstünde farklı ortamlarda
      çalışabilen güçlü ve esnek bir HTTP sunucusu olarak tasarlanmıştır.
      Farklı platformlar ve farklı ortamlar çoğunlukla farklı özellikler veya
      aynı özelliğin en yüksek verimlilikle gerçeklenmesi için farklı yöntemler
      gerektirir. Apache httpd, geniş ortam çeşitliliğini daima modüler
      tasarımı sayesinde uzlaştırmıştır.  Bu tasarım, site yöneticilerine,
      sunucularında bulunmasını istedikleri özellikleri derleme sırasında veya
      çalışma anında gerekli modülleri yüklemek suretiyle seçebilme imkanı
      verir.
    

    
    Apache HTTP Sunucusu 2.0, bu modüler tasarımı sunucunun en temel
      işlevlerine kadar indirmiştir. Sunucu, Çok Süreçlilik Modülleri adı
      verilen ve makine üzerindeki ağ portlarının bağlanmasından, isteklerin
      kabul edilmesinden ve bu istekleri yanıtlayacak çocuklara dağıtmaktan
      sorumlu olan modüllerin seçimine imkan verecek bir yapılanma ile
      gelir.
    

    
    Sunucunun modüler tasarımının bu seviyede genişletilmesi iki önemli
      yarar sağlar:
    

    
      
      
    • Apache httpd geniş çeşitlilikteki işletim sistemlerini daha temiz ve
        daha verimli bir şekilde destekleyebilmektedir. Özellikle,
        mpm_winnt modülü, Apache httpd 1.3’te kullanılan POSIX
        katmanının yerine işletim sistemine özgü özellikleri
        kullanabildiğinden, Apache HTTP Sunucusunun Windows sürümü artık çok
        daha verimli bir duruma gelmiştir. Aynı fayda özelleştirilmiş MPM’lerle
        diğer işletim sistemlerine de sağlanmıştır.
      • 

      
    • Sunucu, belli bir sitenin ihtiyaçlarına uygun olarak daha iyi
        kişiselleştirilebilmektedir. Örneğin, eski yazılım ile uyumluluk ve
        kararlılığa önem veren siteler prefork modülünü
        kullanabilirken, daha geniş ölçeklenebilirlik gerektiren siteler
        worker veya event gibi evreli MPM
        modüllerinden birini seçebilmektedir.
      • 
    
    

    
    Kullanıcı açısından MPM’lerin diğer Apache httpd modüllerinden görünüşte
      bir farkı yoktur. Asıl fark sunucuya yüklenebilecek azami MPM modülü
      sayısının bir ve yalnız bir olarak sınırlanmış olmasıdır. Mevcut MPM
      modülleri modül dizini sayfasında listelenmiştir.
    


    top
    

    

    Öntanımlı MPM’ler
    

    
    Aşağıdaki tabloda çeşitli işletim sistemlerinde öntanımlı olan MPM’ler
      listelenmiştir. Derleme sırasında başka bir seçim yapmadığınız takdirde
      bu işletim sistemlerinde bu MPM’ler seçilmiş olacaktır.

    'Unix' burada Unix benzeri işletim sistemleri anlamında
      kullanılmıştır (örn, Linux, BSD, Solaris, Mac OS X, vb.
    

    
    Unix durumunda, hangi MPM'nin kurulacağı kararı şu 2 soruya verilecek
      yanıta bağlıdır:
    
    
    1. Sistem evreleri destekliyor mu?
    
    
    2. Sistem evreleri "thread-safe polling" anlamında destekliyor mu
      (özellikle kqueue ve epoll işlevlerini)?
    

    
    Her iki soruya da verilen yanıt 'evet' ise, öntanımlı MPM'niz
      event modülüdür.
    

    
    Birincinin yanıtı 'evet' ikincinin 'hayır' ise öntanımlı MPM'niz
      worker modülüdür.
    

    
    Yanıtların her ikisi de 'hayır' ise öntanımlı MPM'niz
      prefork modülüdür.
    

    
    Uygulamada, günümüzdeki işletim sistemlerinin tümü bu iki özelliği
      desteklediğinden öntanımlı MPM'niz hemen hemen daima
      event modülü olacaktır.

    Bir MPM'i bir duruk modül olarak derlemek
    

    
    MPM'ler tüm platformlarda duruk (static) modüller olarak derlenebilir.
      Derleme sırasında tek bir modül seçilir ve sunucu ile ilintilenir. MPM
      değiştirilmek istenirse sunucunun yeniden derlenmesi gerekir.
    

    
    Öntanımlı MPM seçimin değiştirmek için configure
      betiğinin --with-mpm=AD seçeneği kullanılır.
      Buradaki AD istenen MPM'in ismidir.
    

    
    Sunucu bir kere derlendi mi, hangi MPM'in seçilmiş olduğunu
      ./httpd -l komutuyla öğrenebilirsiniz. Bu komut, içerilen
      MPM dahil, sunucu içinde derlenmiş bütüm modülleri listeler.

    Bir MPM'i bir DSO modülü olarak derlemek
    

    
    Unix ve benzeri platformlarda, MPM'ler DSO modülleri olarak derlenebilir
      ve diğer DSO modülleri gibi sunucuya devingen olarak yüklenebilir. DSO
      modülü olarak derlenen MPM'ler, sunucunun yeniden derlenmesini
      gerektirmeden LoadModule yönergesi
      güncellenerek değiştirilebilir.
    

    
    LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
    


    
    LoadModule yönergesini birden
      fazla MPM için kullanmak sunucunun başlatılması sırasında aşağıdaki
      hatanın oluşmasına sebep olur.
    

    
    AH00534: httpd: Configuration error: More than one MPM
    loaded.
    

    
    Bu özellik configure betiğinin
      --enable-mpms-shared seçeneği ile etkinleştirilebilir.
      all değeri belirtilerek platform için
      kullanılabilen tüm modüller kurulur. İstenirse, değer olarak bir MPM
      listesi de belirtilebilir.
    

    
    Özdevinimli olarak seçilerek veya  configure betiğine
      --with-mpm seçeneğiyle belirtilerek seçilen öntanımlı MPM
      üretilen sunucu yapılandırma dosyasıyla yüklenir. Farklı bir MPM seçmek
      için MPM'i LoadModule yönergesinde
      belirtin.

    Le filtrage avec Apache 2
    
    
    
    Modules ApparentésDirectives Apparentées
    


    La chaîne de filtrage est disponible depuis la version 2.0 d'Apache,
et permet aux applications de traiter les données en entrée et en sortie
d'une manière hautement flexible et configurable, quelle que soit la
provenance de ces données.  Il est possible de pré-traiter les données
en entrée, et post-traiter les données en sortie, selon
vos souhaits.
Ces traitements sont tout à fait indépendants des traditionnelles phases
de traitement des requêtes.
    

    
les filtres peuvent s'enchaîner, perpendiculairement au traitement des requêtes

    

    Voici quelques exemples de filtrage avec la distribution standard d'Apache:
    

      

    • mod_include, implémente les inclusions côté serveur.
      • 

    • mod_ssl, implémente le cryptage SSL (https).
      • 

    • mod_deflate, implémente la compression/décompression
à la volée.
      • 

    • mod_charset_lite, transcodage entre différents
jeux de caractères.
      • 

    • mod_ext_filter, utilisation d'un programme externe
comme filtre.
      • 

    

    Apache utilise aussi plusieurs filtres en interne pour accomplir des tâches
comme le découpage des grosses requêtes (chunking) et la gestion des
requêtes portant sur une partie d'un fichier (byte-range).
    


    Un grand choix d'applications sont implémentées par des modules de filtrage
tiers. En voici quelques exemples :
    


      

    • Traitement et réécriture HTML et XML
      • 

    • Transformations XSLT et inclusions XML (XIncludes)
      • 

    • Support de l'espace de nommage XML
      • 

    • Gestion du chargement de fichier et décodage des formulaires HTML
      • 

    • Traitement d'image
      • 

    • Protection des applications vulnérables comme les scripts PHP
      • 

    • Edition de texte par Chercher/Remplacer
      •

    Filtrage intelligent
    


    
Le filtrage intelligent applique différents fournisseurs de filtrage en fonction de l'état du traitement de la requête

    

    mod_filter, inclus dans les version 2.1 et supérieures
d'Apache, permet de configurer la chaîne de filtrage dynamiquement
à l'exécution.
Ainsi par exemple, vous pouvez définir un proxy pour réécrire du code HTML
avec un filtre HTML et traiter des images JPEG avec un filtre totalement
séparé, bien que le proxy ne possède aucune information préliminaire
sur ce que le serveur à l'origine des données à filtrer va envoyer.
Ceci fonctionne grâce à l'utilisation d'un gestionnaire de filtre,
qui distribue les tâches à différents fournisseurs de filtrage en fonction
du contenu réel à filtrer à l'exécution.  Tout filtre peut se voir soit
inséré directement dans la chaîne et lancé inconditionnellement, soit
utilisé comme un fournisseur de filtrage et inséré dynamiquement.
Par exemple,
    

      

    • un filtre de traitement HTML sera lancé uniquement si le contenu est
de type text/html ou application/xhtml+xml
      • 

    • Un filtre de compression sera lancé uniquement si les données en entrée
sont de type compressible et non déjà compressées
      • 

    • Un filtre de conversion de jeux de caractères ne sera inséré que si
le document texte n'est pas déjà dans le jeu de caractères voulu
      • 

    

    top
    

    

    Présentation des filtres en tant que service HTTP
    



    Les filtres permettent de traiter les requêtes des clients avant
traitement par le serveur, ainsi que les contenus issus du serveur avant de les renvoyer
au client. Le module mod_reflector permet aussi
d'utiliser les filtres pour traiter les requêtes des clients avant de
les renvoyer directement à ces derniers.
    


    Le module mod_reflector reçoit les requêtes POST des
clients, et en répercute le corps dans la requête POST constituant la
réponse, lors de l'envoi de cette dernière au client en passant à travers la
pile de filtres en sortie.
    


    Cette technique peut être utilisée comme alternative à un service web
s'exécutant à l'intérieur de la pile d'un serveur d'applications, où un
filtre en sortie effectue la transformation requise sur le corps de la
requête. Par exemple, on peut utiliser le module
mod_deflate pour fournir un service général de
compression ; un filtre de transformation d'images peut aussi se voir
mué en service de transformation d'images.
    


    top
    

    

    Utilisation des filtres
    


    Il y a deux manières d'utiliser le filtrage : Simple et Dynamique.
En général, vous utiliserez l'une ou l'autre méthode; le mélange des deux
peut avoir des conséquences inattendues (bien que le filtrage simple en entrée
puisse être associé sans problème avec le filtrage simple ou dynamique
en sortie).
    

    La méthode Simple est la seule permettant de configurer les filtres
en entrée, et suffit pour les filtres en sortie pour lesquels vous avez besoin
d'une chaîne de filtres statique.
Les directives correspondantes sont
    SetInputFilter,
    SetOutputFilter,
    AddInputFilter,
    AddOutputFilter,
    RemoveInputFilter, et
    RemoveOutputFilter.
    


    La méthode Dynamique permet une configuration dynamique des filtres en
sortie à la fois statique et flexible, comme discuté dans la page
mod_filter.
Les directives correspondantes sont
    FilterChain,
    FilterDeclare, et
    FilterProvider.
    


    Une autre directive AddOutputFilterByType est encore supportée,
mais obsolète. Utilisez la
configuration dynamique à la place.

    Bu belgede Apache HTTP Sunucusunun 1.3 ve 2.0 sürümleri arasındaki
    başlıca değişikliklerin bazılarına değinilmiştir.
    

    


    top
    

    

    Çekirdekteki Gelişmeler
    
    

    
    
      
    Unix Evreleri
    

      
    POSIX evreleri desteği olan Unix sistemlerinde Apache httpd, çok evreli
        kipte çok süreçlilik şeklinde melez bir yapıda çalışır. Bu bir çok
        bakımdan ölçeklenebilirliği arttırsa da bütün yapılandırmalarda
        sağlanamaz.
    

      
    Yeni Paket Derleme Sistemi
    

      
    Yeni kaynak paketi derleme sistemi autoconf ve
        libtool’a dayalı olarak sıfırdan, yeni baştan yazıldı.
        Böylece Apache httpd’nin paket yapılandırma sistemi diğer paketlerinkiyle
        benzerlik kazanmış oldu.
    

      
    Çok Sayıda Protokol Desteği
    

      
    Apache HTTP Sunucusu artık çok sayıda protokol ile hizmet sunacak bir
        alt yapıya sahiptir. Örneğin, mod_echo modülü bu
        amaçla yazılmıştır.
    

      
    Unix dışı platformalara daha iyi destek
    

      
    Apache HTTP Sunucusu 2.0 sürümleri,  BeOS, OS/2, Windows gibi Unix olmayan
        platformlarda daha hızlı ve daha kararlı çalışacak duruma
        getirilmiştir. Genelde iyi geliştirilmemiş olan dolayısıyla istenen
        başarımı sağlayamayan POSIX taklit katmanlarının kullanımından
        vazgeçilmiş, platforma özgü çok süreçlilik
        modülleri (MPM) ve Apache Taşınabilirlik Arayüzü (APR) sayesinde
        bu platformlar artık kendi doğal programlama arayüzleriyle
        gerçeklenir olmuştur.
    

      
    Yeni Apache httpd Programlama Arayüzü
    

      
    Modüller için kullanılan programlama arayüzü 2.0 sürümüyle önemli
        değişikliklere uğramıştır. 1.3 sürümünde görülen modüllerle ilgili
        sıralama/öncelik sorunlarının çoğu giderilmiştir. 2.0 sürümü bu
        işlemleri daha bir özdevimli yapar olmuştur; daha fazla esneklik
        sağlamak için artık kancalı modül sıralaması kullanılabilmektedir.
        Ayrıca, arayüze, Apache HTTP Sunucususu çekirdeğini yamamaya gerek kalmadan
        modüllerle sunucu yeteneklerinin arttırılabilmesini sağlayan yeni
        çağrılar eklenmiştir.
    

      
    IPv6 Desteği
    

      
    IPv6’nın Apache Taşınabilirlik Arayüzü kütüphanesi tarafından
        desteklendiği sistemlerde Apache httpd öntanımlı olarak IPv6 soketlerini
        dinler. Bundan başka, Listen, NameVirtualHost ve VirtualHost yönergelerinin IPv6 sayısal adres
        dizgelerini desteklemesi sağlanmıştır.
    Örnek: Listen
        [2001:db8::1]:8080
    

      
    Süzme
    

      
    Apache httpd modülleri, artık, sunucuya teslim edilen veya sunucudan
        teslim alınan içerik akımları üzerinde süzgeç gibi davranacak şekilde
        yazılabilmektedir. Bu sayede, örneğin CGI betiklerinin çıktılarının
        mod_include modülünün INCLUDES süzgeci
        kullanılarak SSI yönergeleri için çözümlenmesi mümkündür. CGI
        programlarının birer eylemci olarak davranması gibi,
        mod_ext_filter modülü de harici programların birer
        süzgeç olarak davranabilmesini mümkün kılar.
    

      
    Çok Dilli Hata Yanıtları
    

      
    Hata yanıtlarının tarayıcılara yönelik iletileri artık SSI
        belgeleri kullanılarak çeşitli dillerde sağlanabilmektedir. Bunlar
        ayrıca yönetici tarafından görünüş ve kullanışlılık tutarlılığı
        bakımından kişiselleştirilebilmektedir.
    

      
    Basitleştirilmiş Yapılandırma
    

      
    Bazı yönergelerle ilgili kafa karışıklıkları giderilmiştir.
        Bilhassa belli bir IP adresini dinlemek için kullanılan
        Port ve BindAddress yönergeleri ile ilgili
        karışıklığın önüne geçmek için sadece Listen yönergesi yeterli olmaktadır. ServerName yönergesi ise sadece yönlendirme
        ve sanal konak tanıma amacıyla sunucu ismi ve port belirtiminde
        kullanılmaktadır.
    

      
    Doğal Windows NT Unicode Desteği
    

      
    Apache httpd 2.0, Windows NT üzerinde artık tüm dosya sistemi
        kodlamalarında utf-8 kullanmaktadır. Bu destek, Windows 2000 ve
        Windows XP dahil tüm Windows NT temelli sistemlere çok dillilik
        desteğini sağlamak üzere mevcut Unicode dosya sistemine doğrudan
        uyarlanır. Dosya sisteminde makinenin yerel karakter kodlamasını
        kullanan kullanan Windows 95, 98 ve ME için bu destek
        yoktur.
    

      
    Düzenli İfade Kütüphanesi Güncellemesi
    

      
    Apache httpd 2.0’da Perl uyumlu düzenli
        ifade kütüphanesi bulunur. Tüm düzenli ifadelerde artık çok daha
        güçlü olan Perl 5 sözdizimi kullanılmaktadır.
    

    
    
  
    top
    

    

    Modüllerdeki Gelişmeler
    
    

    
    
      
    mod_ssl
    

      
    Apache httpd 2.0’da yeni olan bu modül,  OpenSSL tarafından sağlanan
        SSL/TLS şifreleme protokollerine bir arayüzdür.
    

      
    mod_dav
    

      
    Apache httpd 2.0’da yeni olan bu modül, site içeriğinin destek ve bakımı
        için HTTP dağıtık yazım ve sürüm yönetimi (DAV - Distributed
        Authoring and Versioning) belirtimini gerçekler.
    

      
    mod_deflate
    

      
    Apache httpd 2.0’da yeni olan bu modül sayesinde ağ band genişliğinden
        daha verimli yararlanabilmek için içeriğin sıkıştırılarak
        gönderilmesini talep eden tarayıcıların desteklenmesi mümkün
        olmuştur.
    

      
    mod_auth_ldap
    

      
    Apache httpd 2.0.41’de yeni olan bu modül, HTTP temel kimlik
        doğrulamasında kullanılan delillerin saklanması için LDAP
        veritabanının kullanılabilmesini mümkün kılar. Kardeş modülü olan
        mod_ldap ise bağlantı havuzlaması ve sonuçların
        önbelleğe alınması ile ilgilenir.
    

      
    mod_auth_digest
    

      
    Paylaşımlı belleği kullanan süreçlere karşı oturum önbelleklemesi
        için ek destek içerir.
    

      
    mod_charset_lite
    

      
    Apache httpd 2.0’da yeni olan bu deneysel modül, karakter kümesi
        dönüşümleri veya kaydı için destek sağlar.
    

      
    mod_file_cache
    

      
    Apache httpd 2.0’da yeni olan bu modül, Apache HHP Sunucusu 1.3’teki
        mod_mmap_static modülünün işlevselliğini içermenin
        yanında buna önbellekleme yetenekleri de ekler.
    

      
    mod_headers
    

      
    Bu modül Apache httpd 2.0’da daha esnek hale getirilmiştir. Artık
        mod_proxy tarafından kullanılan istek başlıkları
        değiştirilebilmekte ve bunlar yanıt başlıklarına şartlı olarak
        atanabilmektedir.
    

      
    mod_proxy
    

      
    Bu modül HTTP/1.1 uyumlu vekaleti daha güvenilir kılmak ve yeni
        süzgeç alt yapısının getirilerinden de yararlanmak amacıyla yeni
        baştan yazılmıştır. Bunun yanında, <Proxy> bölümünün yeni hali vekil siteleri
        desteklemek bakımından daha okunabilir (ve kendi içinde daha hızlı)
        olması sağlanmıştır; <Directory "proxy:...">
        yapılandırması artık desteklenmemektedir. Modül,
        proxy_connect, proxy_ftp ve
        proxy_http şeklinde her biri belli bir protokolü
        destekleyen ayrı modüllere bölünmüştür.
    

      
    mod_negotiation
    

      
    Yeni ForceLanguagePriority yönergesi sayesinde istemciye
        “Kabul edilebilir bir gösterim çeşidi yok” ya da “Çok sayıda seçim
        belirtilmiş” yanıtını döndürmek yerine tüm durumlara uyan bir
        sayfanın gönderilebilmesi sağlanmıştır. Bundan başka, uzlaşım ve
        MultiViews algoritmaları daha tutarlı sonuçlar elde
        etmek amacıyla elden geçirilmiş ve belge içeriği ile daha iyi eşleşen
        yeni bir tür eşlem yapısı sağlanmıştır.
    

      
    mod_autoindex
    

      
    Dizin içeriklerinin özdevimli listelenmesi artık HTML tabloları
        kullanılacak şekilde yapılandırılabilmektedir. Böylece sayfa daha iyi
        biçemlenebilmekte, içerik daha hassas sıralanabilmekte, sürüm
        numarasına göre sıralama yapılabilmekte ve dosya ismi kalıpları
        kullanılarak sadece istenen içerik listelenebilmektedir.
    

      
    mod_include
    

      
    Yeni yönergeler, değiştirilecek SSI elemanları için öntanımlı
        başlangıç ve bitiş etiketlerine izin vermekte, hataların ve zaman
        biçemleme yapılandırmalarının SSI belgesinde değil ana yapılandırma
        dosyasında bulunması mümkün olmaktadır. Düzenli ifadelerin gruplanmış
        sonuçları (Perl düzenli ifade sözdizimi kullanılmaktadır)
        mod_include modülünün $0 ..
        $9 değişkenleri sayesinde kullanılabilmektedir.
    

      
    mod_auth_dbm
    

      
    AuthDBMType yönergesi
        sayesinde artık çok sayıda DBM tarzı veritabanı türü
        desteklenmektedir.

    This document covers compilation and installation of the Apache HTTP Server
    on Unix and Unix-like systems only. For compiling and
    installation on Windows, see Using Apache HTTP Server with Microsoft
    Windows and Compiling Apache for Microsoft Windows.
    For other platforms, see the platform documentation.
    

    
    Apache httpd uses libtool and autoconf
    to create a build environment that looks like many other Open Source
    projects.
    

    
    If you are upgrading from one minor version to the next (for
    example, 2.4.8 to 2.4.9), please skip down to the upgrading section.

    Overview for the
    impatient
    

    
    
    
    Installing on Fedora/CentOS/Red Hat Enterprise Linux
    
    
    
    
    sudo yum install httpd
sudo systemctl enable httpd
sudo systemctl start httpd
    


    
    Newer releases of these distros use
    dnf rather than yum. See the
    Fedora project's documentation for platform-specific notes.
    
    
    

    
    Installing on Ubuntu/Debian
    
    
    

    sudo apt install apache2
sudo service apache2 start
    


    
    See Ubuntu's documentation for platform-specific notes.
    

    
    

    
    Installing from source
    
    
    
    
    
      
      
    
        Download

        Download the latest release from http://httpd.apache.org/download.cgi
        
      
    

      
    
        Extract

        $ gzip -d httpd-NN.tar.gz
    
         $ tar xvf httpd-NN.tar
    
         $ cd httpd-NN    		
      
    

      
    
        Configure

        $ ./configure --prefix=PREFIX
        
      
    

      
    
        Compile

        $ make 
      
    

      
    
        Install

        $ make install 
      
    

      
    
        Customize

        $ vi PREFIX/conf/httpd.conf 
      
    

      
    
        Test

        $ PREFIX/bin/apachectl -k start
        
      
    
    
    

        
    NN must be replaced with the current version
        number, and PREFIX must be replaced with the
        filesystem path under which the server should be installed. If
        PREFIX is not specified, it defaults to
        /usr/local/apache2.
    

        
    Each section of the compilation and installation process is
        described in more detail below, beginning with the requirements
        for compiling and installing Apache httpd.

    Requirements
    

    
    The following requirements exist for building Apache httpd:
    

    
    
      
    APR and APR-Util
    
      
    Make sure you have APR and APR-Util already installed on
      your system. If you don't, or prefer to not use the system-provided
      versions, download the latest versions of both APR and APR-Util
      from Apache APR, unpack
      them into /httpd_source_tree_root/srclib/apr and /httpd_source_tree_root/srclib/apr-util
      (be sure the directory names do not have version numbers; for example,
      the APR distribution must be under /httpd_source_tree_root/srclib/apr/) and use
      ./configure's --with-included-apr
      option.  On some platforms, you may have to install the
      corresponding -dev packages to allow httpd to build
      against your installed copy of APR and APR-Util.
    

      
    Perl-Compatible Regular Expressions Library (PCRE)
    
      
    This library is required but not longer bundled with httpd.
      Download the source code from http://www.pcre.org,
      or install a Port or Package.  If your build system can't find
      the pcre-config script installed by the PCRE build, point to it
      using the --with-pcre parameter.  On some platforms,
      you may have to install the corresponding -dev
      package to allow httpd to build against your installed copy
      of PCRE.
    

      
    Disk Space
    
      
    Make sure you have at least 50 MB of temporary free disk
      space available. After installation the server occupies
      approximately 10 MB of disk space. The actual disk space
      requirements will vary considerably based on your chosen
      configuration options, any third-party modules, and, of course,
      the size of the web site or sites that you have on the server.
    

      
    ANSI-C Compiler and Build System
    
      
    Make sure you have an ANSI-C compiler installed. The GNU C
      compiler (GCC) from the Free Software Foundation (FSF)
      is recommended. If you don't have GCC
      then at least make sure your vendor's compiler is ANSI
      compliant. In addition, your PATH must contain
      basic build tools such as make.
    

      
    Accurate time keeping
    
      
    Elements of the HTTP protocol are expressed as the time of
      day. So, it's time to investigate setting some time
      synchronization facility on your system. Usually the
      ntpdate or xntpd programs are used for
      this purpose which are based on the Network Time Protocol (NTP).
      See the NTP
      homepage for more details about NTP software and public
      time servers.
    

      
    Perl 5
      [OPTIONAL]
    
      
    For some of the support scripts like apxs or dbmmanage (which are
      written in Perl) the Perl 5 interpreter is required (versions
      5.003 or newer are sufficient).  If no Perl 5 interpreter is found by the
      configure script, you will not be able to use
      the affected support scripts. Of course, you will still be able to
      build and use Apache httpd.
    
    
    

    top
    

    

    Download
    

    
    The Apache HTTP Server can be downloaded from the Apache HTTP Server
    download site, which lists several mirrors.  Most users of
    Apache on unix-like systems will be better off downloading and
    compiling a source version.  The build process (described below) is
    easy, and it allows you to customize your server to suit your needs.
    In addition, binary releases are often not up to date with the latest
    source releases.  If you do download a binary, follow the instructions
    in the INSTALL.bindist file inside the distribution.
    

    
    After downloading, it is important to verify that you have a
    complete and unmodified version of the Apache HTTP Server. This
    can be accomplished by testing the downloaded tarball against the
    PGP signature.  Details on how to do this are available on the download
    page and an extended example is available describing the use of
    PGP.
    


    top
    

    

    Extract
    

    
    Extracting the source from the Apache HTTP Server tarball is a
    simple matter of uncompressing, and then untarring:
    


    
$ gzip -d httpd-NN.tar.gz
    
$ tar xvf httpd-NN.tar

    

    
    This will create a new directory under the current directory
    containing the source code for the distribution. You should
    cd into that directory before proceeding with
    compiling the server.
    

    top
    

    

    Configuring the source tree
    

    
    The next step is to configure the Apache source tree for your
    particular platform and personal requirements. This is done using
    the script configure included in
    the root directory of the distribution. (Developers downloading
    an unreleased version of the Apache source tree will need to have
    autoconf and libtool installed and will
    need to run buildconf before proceeding with the next
    steps. This is not necessary for official releases.)
    

    
    To configure the source tree using all the default options,
    simply type ./configure. To change the default
    options, configure accepts a variety of variables
    and command line options.
    

    
    The most important option is the location --prefix
    where Apache is to be installed later, because Apache has to be
    configured for this location to work correctly.  More fine-tuned
    control of the location of files is possible with additional configure
    options.
    

    
    Also at this point, you can specify which features you
    want included in Apache by enabling and disabling modules.  Apache comes with a wide range of modules
    included by default.  They will be compiled as
    shared objects (DSOs) which can be loaded
    or unloaded at runtime.
    You can also choose to compile modules statically by using the option
    --enable-module=static.
    

    
    Additional modules are enabled using the
    --enable-module option, where
    module is the name of the module with the
    mod_ string removed and with any underscore converted
    to a dash.  Similarly, you can disable modules with the
    --disable-module option.  Be careful when
    using these options, since configure cannot warn you
    if the module you specify does not exist; it will simply ignore the
    option.
    

    
    In addition, it is sometimes necessary to provide the
    configure script with extra information about the
    location of your compiler, libraries, or header files.  This is
    done by passing either environment variables or command line
    options to configure.  For more information, see the
    configure manual page. Or invoke
    configure using the --help option.
    

    
    For a short impression of what possibilities you have, here
    is a typical example which compiles Apache for the installation
    tree /sw/pkg/apache with a particular compiler and flags
    plus the two additional modules mod_ldap and
    mod_lua:
    


    
      $ CC="pgcc" CFLAGS="-O2" \
    
       ./configure --prefix=/sw/pkg/apache \
    
       --enable-ldap=shared \
    
       --enable-lua=shared

    

    
    When configure is run it will take several minutes to
    test for the availability of features on your system and build
    Makefiles which will later be used to compile the server.
    

    
    Details on all the different configure options are
    available on the configure manual page.
    

    top
    

    

    Build
    

    
    Now you can build the various parts which form the Apache
    package by simply running the command:
    


    $ make
    

    
    Please be patient here, since a base configuration takes
    several minutes to compile and the time will vary widely
    depending on your hardware and the number of modules that you
    have enabled.
    

    top
    

    

    Install
    

    
    Now it's time to install the package under the configured
    installation PREFIX (see --prefix option
    above) by running:
    


    $ make install
    

    
    This step will typically require root privileges, since
    PREFIX is usually a directory with restricted write
    permissions.
    

    
    If you are upgrading, the installation will not overwrite
    your configuration files or documents.
    

    top
    

    

    Customize
    

    
    Next, you can customize your Apache HTTP server by editing
    the configuration files under
    PREFIX/conf/.
    


    $ vi PREFIX/conf/httpd.conf
    

    
    Have a look at the Apache manual under
    PREFIX/docs/manual/ or consult http://httpd.apache.org/docs/2.4/ for the most recent
    version of this manual and a complete reference of available configuration directives.
    

    top
    

    

    Test
    

    
    Now you can start your Apache
    HTTP server by immediately running:
    


    $ PREFIX/bin/apachectl -k start
    

    
    You should then be able to request your first document
    via the URL http://localhost/. The web page you see is located
    under the DocumentRoot,
    which will usually be PREFIX/htdocs/.
    Then stop the server again by
    running:
    


    $ PREFIX/bin/apachectl -k stop
    

    top
    

    

    Upgrading
    

    
    The first step in upgrading is to read the release announcement
    and the file CHANGES in the source distribution to
    find any changes that may affect your site.  When changing between
    major releases (for example, from 2.0 to 2.2 or from 2.2 to 2.4),
    there will likely be major differences in the compile-time and
    run-time configuration that will require manual adjustments.  All
    modules will also need to be upgraded to accommodate changes in the
    module API.
    

    
    Upgrading from one minor version to the next (for example, from
    2.2.55 to 2.2.57) is easier.  The make install
    process will not overwrite any of your existing documents, log
    files, or configuration files.  In addition, the developers make
    every effort to avoid incompatible changes in the
    configure options, run-time configuration, or the
    module API between minor versions.  In most cases you should be able to
    use an identical configure command line, an identical
    configuration file, and all of your modules should continue to
    work.
    

    
    To upgrade across minor versions, start by finding the file
    config.nice in the build directory of
    your installed server or at the root of the source tree for your
    old install.  This will contain the exact
    configure command line that you used to
    configure the source tree.  Then to upgrade from one version to
    the next, you need only copy the config.nice file to
    the source tree of the new version, edit it to make any desired
    changes, and then run:
    

    
    
    $ ./config.nice
    
    $ make
    
    $ make install
    
    $ PREFIX/bin/apachectl -k graceful-stop
    
    $ PREFIX/bin/apachectl -k start
    
    
    

    
    You should always test any new version in your
    environment before putting it into production.  For example, you
    can install and run the new version along side the old one by
    using a different --prefix and a
    different port (by adjusting the Listen directive) to test for any
    incompatibilities before doing the final upgrade.
    

    
    You can pass additional arguments to config.nice,
    which will be appended to your original configure
    options:
    

    
    
    $ ./config.nice --prefix=/home/test/apache --with-port=90
    
    

    top
    

    

    Third-party packages
    

    
    A large number of third parties provide their own packaged
    distributions of the Apache HTTP Server for installation on
    particular platforms. This includes the various Linux distributions,
    various third-party Windows packages, Mac OS X, Solaris, and many
    more.
    

    
    Our software license not only permits, but encourages, this kind
    of redistribution. However, it does result in a situation where the
    configuration layout and defaults on your installation of the server
    may differ from what is stated in the documentation. While
    unfortunate, this situation is not likely to change any time
    soon.
    

    
    A description
    of these third-party distributions is maintained in the HTTP
    Server wiki, and should reflect the current state of these
    third-party distributions. However, you will need to familiarize
    yourself with your particular platform's package management and
    installation procedures.

    この文書では、Apache HTTP サーバを設定するのに使用するファイルについて
記述しています。
    

    


    top
    

    

    メインの設定ファイル
    
    
    
    関連モジュール関連ディレクティブ
    

    
    Apache は ディレクティブ を設定ファイルに平文で書くことにより設定します。
    メインの設定ファイルは普通は httpd.conf という名前です。
    このファイルの位置はコンパイル時に設定されますが、コマンドラインの
    -f フラグにより上書きできます。
    また、他の設定ファイルを Include
    ディレクティブによって追加でき、ワイルドカードを使用して多数の
    設定ファイルを追加することができます。
    どんなディレクティブも、これらの設定ファイルどれにでも入れることができます。
    Apache は起動時か再起動時のみメイン設定ファイルの変更を認識します。
    

    
    サーバは MIME
    ドキュメントタイプを含んでいるファイルも読み込みます。ファイル名は
    TypesConfig
    で設定され、デフォルトでは mime.types
    になっています。
    
  
    top
    

    

    設定ファイルの構文
    
    

    
    Apache の設定ファイルは 1 行に 1 つのディレクティブからなります。
    バックスラッシュ "\" はディレクティブが次の行に継続していることを
    示すために行の最後の文字として使われているかもしれません。
    行の最後とバックスラッシュの間に他の文字や空白があってはいけません。
    
    

    
    設定ファイルのディレクティブは大文字小文字を区別しませんが、
    引数にはしばしば区別するものがあります。ハッシュ文字 "#"
    で始まる行はコメントと見なされて無視されます。
    設定ディレクティブと同一行の末尾にコメントが含まれていてはいけません。ディレクティブの前の空行と空白は無視されますので、
    わかりやすくするためにディレクティブをインデントしても構いません。
    
    

    
    設定ファイルの構文エラーは、
    apachectl configtest
    かコマンドラインオプション
    -t を使って調べられます。
    
  
    top
    

    

    モジュール
    
    

    
    関連モジュール関連ディレクティブ
    

    
    Apache はモジュール化されたサーバです。
    コアサーバには最も基本的な機能だけが含まれています。拡張機能は
    Apache にロードされるモジュールとして利用可能です。デフォルトでは、コンパイル時にモジュールの
    Base セット (基本セット) が
    サーバに含まれます。サーバが動的ロードモジュールを使うようにコンパイルされている場合は、
    モジュールを別にコンパイルして、いつでも
    LoadModule
    ディレクティブを使って追加できます。
    そうでない場合は、モジュールの追加や削除をするためには Apache
    を再コンパイルする必要があります。設定ディレクティブは <IfModule>
    ブロックに入れることで特定のモジュールが存在するときだけ
    設定ファイルに含まれるようにすることができます。
    

    
    コマンドラインオプション -l を使って現時点で
    どのモジュールがサーバにコンパイルされているかを知ることができます。
    
  
    top
    

    

    ディレクティブの適用範囲
    
    

    
    関連モジュール関連ディレクティブ
    

    
    メイン設定ファイルにあるディレクティブはサーバ全体に適用されます。
    サーバの一部分の設定だけを変更したい場合は <Directory>, <DirectoryMatch>, <Files>, <FilesMatch>, <Location>, <LocationMatch>
    セクションの中に置くことで適用範囲を決められます。
    これらのセクションはその中にあるディレクティブの適用範囲を
    特定のファイルシステムの位置や URL に限定します。
    非常に細粒度の設定を可能にするために、
    セクションを入れ子にすることもできます。
    

    
    Apache は同時に多くの違うウェブサイトを扱う能力があります。
    これは バーチャルホスト と呼ばれています。
    特定のウェブサイトにのみ適用されるようにするために、
    ディレクティブは
    <VirtualHost>
    セクションの中に置くことでも適用範囲を変えることができます。
    

    
    ほとんどのディレクティブはどのセクションにでも書けますが、
    中にはコンテキストによっては意味をなさないものもあります。
    例えば、プロセスの作成を制御しているディレクティブはメインサーバの
    コンテキストにのみ書くことができます。
    どのディレクティブをどのセクションに書くことができるかを知るためには
    ディレクティブの コンテキスト を調べてください。詳しい情報は、
    Directory, Location, Files
    セクションの動作法にあります。
    
  
    top
    

    

    .htaccess ファイル
    
    

    
    関連モジュール関連ディレクティブ
    

    
    Apache ではウェブツリーの中に置かれた特別なファイルを使って
    非中央集権的な設定管理をできます。その特別なファイルは普通は
    .htaccess という名前で、
    AccessFileName
    ディレクティブでどんな名前にでも指定できます。
    .htaccess
    ファイルに書かれたディレクティブはファイルを置いた
    ディレクトリとその全てのサブディレクトリに適用されます。
    .htaccess ファイルは、メインの設定ファイルと同じ
    構文を使います。
    .htaccess
    ファイルはすべてのリクエストで読み込まれるため、
    変更はすぐに反映されます。
    

    
    どのディレクティブが .htaccess
    ファイルに書けるかを調べるには、ディレクティブのコンテキスト
    を調べてください。サーバ管理者はさらにメイン設定ファイルの
    AllowOverride
    を設定することでどのディレクティブを .htaccess
    ファイルに書けるようにするかを制御することができます。
    

    
    .htaccess ファイルに関する詳しい情報は
    .htaccess チュートリアル
    を参照してください。

            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    


    この文書ではマルチプロセッシングモジュールがどのようなもので、
Apache HTTP サーバでどのように使用されるかについて解説しています。
    

    


    top
    

    

    はじめに
    

    
    Apache HTTP サーバは異なる幅広い環境、多種多様なプラットホームで
    動作するように、パワフルで柔軟性に富んだ設計になっています。
    異なるプラットホーム・異なる環境ではしばしば、
    異なる機能が必要になったり、
    同じ機能でも効率のために異なる実装が必要になったりします。
    Apache ではモジュール化された設計により幅広い環境に適応してきました。
    この設計のおかげで、管理者は
    コンパイル時または実行時にどのモジュールをロードするか選ぶことによって、
    どの機能をサーバに取り込むか選択することができます。
    

    
    Apache 2.0 では、
    このモジュール化された設計をサーバの基本機能にまで拡張しました。
    サーバには精選されたマルチプロセッシングモジュール (MPM) 
    が付いてきて、これらはマシンのネットワークポートをバインドしたり、
    リクエストを受け付けたり、リクエストを扱うよう子プロセスに割り当てたり、
    といった役割を持ちます。
    

    
    モジュール化された設計をサーバのこのレベルまで拡張することで
    二つの重要な利点が生まれます:
    

    
      
      
    • Apache は幅広いオペレーティングシステムを
      より美しく効率的にサポートできます。
      特に Windows 版の Apache は随分効率的になりました。
      なぜなら mpm_winnt
      によって、Apache 1.3 で用いられていた POSIX 
      レイヤの代わりにネイティブのネットワーク機能を
      利用できるからです。
      特別化された MPM 
      を実装した他のオペレーティングシステムでも、
      同様にこの利点は生まれます。
      • 

      
    • サーバは特定のサイト向けに、より上手にカスタマイズできます。
      例えば、非常に大きなスケーラビリティを必要とするサイトでは、
      worker や event といったスレッド化された
      MPM を利用できる一方で、安定性や古いソフトウェアとの互換性を
      必要とするサイトでは prefork
      が利用できます。
      • 
    
    

    
    ユーザレベルでは、MPM は他の Apache 
    モジュールと同等に見えます。
    主な違いは、いつでも唯一の MPM 
    がロードされなければならないという点です。
    利用可能な MPM は 
    module インデックスにあります。
    


    top
    

    

    MPM を選ぶ
    

    
    MPM は設定中に選択して、サーバ内部にコンパイルされなければ
    なりません。
    コンパイラは、スレッドが使用されている場合に様々な機能を最適化できますが、
    そのためにはそもそもスレッドが使われているということを知る必要があります。
    

    
    望みの MPM を実際に選ぶためには、configure スクリプトで
    --with-mpm=NAME 引数を用いてください。
    NAME は望みの MPM の名前です。
    

    
    サーバコンパイル後は、どの MPM が選択されたかを
    ./httpd -l で確かめることができます。
    このコマンドは、MPM
    を含め、サーバにコンパイルで組み込まれたモジュール全てを
    列挙します。
    

    top
    

    

    MPM デフォルト値
    


    次表に様々な OS 向けのデフォルトの MPM 一覧を掲載しています。
コンパイル時に意図的に他を選択しなければ、自動的にこれらの MPM
が選択されます。

    Le serveur HTTP Apache fournit des messages d'erreur génériques
    pour les codes de statut 4xx ou 5xx ; ces messages sont cependant
    relativement austères, imprécis, et peuvent s'avérer intimidants
    pour les visiteurs du site. Si vous le souhaitez, vous pouvez
    afficher des messages d'erreur plus conviviaux, dans un langage
    autre que l'anglais, ou même sous une forme plus en adéquation avec
    le style de votre site.
    

    
    Il est possible de définir des messages d'erreur personnalisés
    pour chaque code de statut HTTP associé à une condition d'erreur -
    c'est à dire tout code de statut 4xx ou 5xx.
    

    
    De plus, il est possible de
    personnaliser le message d'erreur en fonction d'un jeu de valeurs
    fourni, en utilisant les Inclusions Côté
    Serveur (SSI). Un programme CGI ou un autre gestionnaire
    dynamique (PHP, mod_perl, etc...) peut aussi utiliser ces variables
    pour gérer les conditions d'erreur.
    


  
    


    top
    

    

    Configuration
    

    
    Les messages d'erreur personnalisés sont configurés via la
    directive ErrorDocument, qui
    peut être utilisée dans un contexte global, serveur virtuel ou
    répertoire. On peut utiliser cette directive dans les fichiers
    .htaccess si AllowOverride est
    définie à FileInfo.
    

    
    ErrorDocument 500 "Désolé, notre script s'est
crashé ; comme c'est dommage !"
ErrorDocument 500 /cgi-bin/crash-recover
ErrorDocument 500 http://error.example.com/server_error.html
ErrorDocument 404 /errors/not_found.html 
ErrorDocument 401 /subscription/how_to_subscribe.html
    



    La syntaxe de la directive ErrorDocument est :
    
      
    ErrorDocument <code_3_chiffres> <action>
    

      
    où action peut être traitée comme :
    
        
      
      
    1. Une URL de redirection local (si l'action commence par un "/").
      2. 
      
    2. Une URL de redirection externe (si action est une URL valide).
      3. 
      
    3. Le texte à afficher (si l'action ne répond à aucune des
      deux conditions précédentes). Entourez le texte de guillemets (")
      s'il contient plusieurs mots.
      4. 
        
    

    
    Dans le cas d'une redirection vers une URL locale, des variables
    d'environnement supplémentaires sont définies de façon à ce que la
    réponse puisse être personnalisée par la suite. Elles ne sont pas
    envoyées aux URLs externes.
    

  
    top
    

    

    Variables disponibles
    

      
    La redirection vers une autre URL peut être utile, mais
      seulement s'il est possible de transmettre certaines informations
      qui pourront être utilisées pour expliquer ou journaliser
      la condition d'erreur ou le problème plus clairement.
    

	
    Pour y parvenir, lorsque la redirection d'erreur est envoyée,
	des variables d'environnement supplémentaires sont définies à
	partir des en-têtes de la requête originale en préfixant le nom
	d'origine de l'en-tête par 'REDIRECT_', ce qui permet de fournir au
	message d'erreur le contexte de la requête originelle.
    

      
    Par exemple, en plus des variables d'environnement habituelles,
      vous pouvez recevoir ce qui suit :
    


      
    
        REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/jpeg, image/png
    
        REDIRECT_HTTP_USER_AGENT=Mozilla/5.0 Fedora/3.5.8-1.fc12 Firefox/3.5.8
    
        REDIRECT_PATH=.:/bin:/usr/local/bin:/sbin
    
        REDIRECT_QUERY_STRING=
    
        REDIRECT_REMOTE_ADDR=121.345.78.123
    
        REDIRECT_REMOTE_HOST=client.example.com
    
        REDIRECT_SERVER_NAME=www.example.edu
    
        REDIRECT_SERVER_PORT=80
    
        REDIRECT_SERVER_SOFTWARE=Apache/2.2.15
    
        REDIRECT_URL=/cgi-bin/buggy.pl
      
    

      
    Les variables d'environnement REDIRECT_ sont
      créées à partir des variables d'environnement préexistantes à la
      redirection qui sont préfixées par la chaîne REDIRECT_ ;
      par exemple, HTTP_USER_AGENT devient
      REDIRECT_HTTP_USER_AGENT.
    

      
    REDIRECT_URL, REDIRECT_STATUS, et
      REDIRECT_QUERY_STRING sont systématiquement définies,
      les autres variables n'étant définies que si l'en-tête
      correspondant existait avant la condition d'erreur.
    

      
    Aucune d'entre elles ne sera définie si votre
      directive ErrorDocument
      spécifie une redirection externe (toute URL commençant
      par un protocole du style http:, même si elle fait
      référence au même hôte que le serveur).
    

  
    top
    

    

    Personnalisation des messages d'erreur
    


	
    Si vous faites pointer votre directive
	ErrorDocument vers certains gestionnaires
	dynamiques comme les inclusions côté serveur, les scripts CGI ou
	d'autres gestionnaires, vous pouvez utiliser les variables
	d'environnement supplémentaires disponibles pour personnaliser
	le message.
    


      
    Si la directive ErrorDname-basedocument spécifie une redirection locale
      vers un script CGI, ce dernier doit ajouter un en-tête
      "Status:" dans sa sortie afin de s'assurer du bon
      acheminement jusqu'au client de la condition d'erreur qui a
      provoqué cette redirection. Par exemple, un script Perl spécifié
      par une directive ErrorDocument pourrait contenir ce qui suit
      :
    

      
    ...
print  "Content-type: text/html\n"; 
printf "Status: %s Condition Intercepted\n", $ENV{"REDIRECT_STATUS"}; 
...
    


      
    Si un script est dédié à la gestion d'une condition d'erreur
      spécifique, telle que 404 Not Found, il
      peut utiliser le code et le texte de l'erreur spécifiques à la
      place.
    

      
    Notez que si la réponse contient un en-tête
      Location: (afin d'initier une redirection côté
      client), le script doit émettre un en-tête approprié
      (comme 302 Found). Dans le cas contraire,
      l'en-tête Location: ne produira aucun effet.
    
  
    top
    

    

    Messages d'erreur personnalisés
  multilingues
    

    
    Vous trouverez dans la distribution du serveur HTTP Apache un
    répertoire contenant des messages d'erreur personnalisés traduits en
    16 langues différentes. Pour activer cette fonctionnalité, vous
    pouvez aussi inclure un fichier de configuration qui se trouve dans
    le répertoire de configuration conf/extra.
    

    
    Dans le fichier de configuration de votre serveur, vous trouverez
    un groupe de lignes du style :
    

    
        # Multi-language error messages
    #Include conf/extra/httpd-multilang-errordoc.conf
    


    
    Décommentez la ligne Include pour activer cette
    fonctionnalité, et présenter des messages d'erreur dont le langage
    sera négocié en fonction du langage préféré défini au niveau du
    navigateur du client.
    

    
    De plus, ces documents contiennent diverses variables
    REDIRECT_, de façon à ce que l'utilisateur final
    dispose d'informations supplémentaires à propos de ce qui a pu se
    produire, et de ce qu'il est susceptible de faire maintenant.
    

    
    Ces documents peuvent être personnalisés en fournissant autant
    d'informations utiles que vous le souhaitez aux utilisateurs à
    propos de votre site, et de ce qu'ils sont susceptibles d'y trouver.
    

    
    Pour pouvoir utiliser cette fonctionnalité, vous devez activer
    mod_include et mod_negotiation.

    Configuring Apache HTTP Server to listen on specific addresses and ports.
    
  
    


    top
    

    

    Overview
    
    

    
    Related ModulesRelated Directives
    


    
    When httpd starts, it binds to some port and address on
    the local machine and waits for incoming requests. By default,
    it listens to all addresses on the machine. However, it may need to
    be told to listen on specific ports, or only on selected
    addresses, or a combination of both. This is often combined with the
    Virtual Host feature, which determines how
    httpd responds to different IP addresses, hostnames and
    ports.
    

    
    The Listen
    directive tells the server to accept
    incoming requests only on the specified port(s) or
    address-and-port combinations. If only a port number is
    specified in the Listen
    directive, the server listens to the given port on all interfaces.
    If an IP address is given as well as a port, the server will listen
    on the given port and interface. Multiple Listen directives may be used to
    specify a number of addresses and ports to listen on. The
    server will respond to requests from any of the listed
    addresses and ports.
    

    
    For example, to make the server accept connections on both
    port 80 and port 8000, on all interfaces, use:
    

    
    Listen 80
Listen 8000
    

    

    
    To make the server accept connections on port 80 for one interface,
       and port 8000 on another, use
    

    
    Listen 192.0.2.1:80
Listen 192.0.2.5:8000
    

    

    
    IPv6 addresses must be enclosed in square brackets, as in the
    following example:
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    

    

    
    Overlapping Listen directives will result in a
    fatal error which will prevent the server from starting up.
    

    
    
      (48)Address already in use: make_sock: could not bind to address [::]:80
    
    

    
    See the
    discussion in the wiki for further troubleshooting tips.

    Changing Listen configuration on restart
    
    

    
    When httpd is restarted, special consideration must be made for
    changes to Listen directives.  During a restart, httpd keeps ports
    bound (as in the original configuration) to avoid generating
    "Connection refused" errors for any new attempts to connect to the
    server. If changes are made to the set of Listen directives used
    which conflict with the old configuration, configuration will fail
    and the server will terminate.
    

    
    For example, changing from configuration:
    
    
    
    Listen 127.0.0.1:80
    

    

    
    to the following may fail, because binding to port 80 across
    all addresses conflicts with binding to port 80 on just
    127.0.0.1.
    
    
    
    Listen 80
    

    

    
    To have such configuration changes take effect, it is necessary
    to stop and then start the server.
    
    
  
    top
    

    

    Special IPv6 Considerations
    
    

    
    A growing number of platforms implement IPv6, and
    APR supports IPv6 on most of these platforms,
    allowing httpd to allocate IPv6 sockets, and to handle requests sent
    over IPv6.
    

    
    One complicating factor for httpd administrators is whether or
    not an IPv6 socket can handle both IPv4 connections and IPv6
    connections. Handling IPv4 connections with an IPv6 socket uses
    IPv4-mapped IPv6 addresses, which are allowed by default on most
    platforms, but are disallowed by default on FreeBSD, NetBSD, and
    OpenBSD, in order to match the system-wide policy on those
    platforms. On systems where it is disallowed by default, a
    special configure parameter can change this behavior
    for httpd.
    

    
    On the other hand, on some platforms, such as Linux and Tru64, the
    only way to handle both IPv6 and IPv4 is to use
    mapped addresses. If you want httpd to handle IPv4 and IPv6 connections
    with a minimum of sockets, which requires using IPv4-mapped IPv6
    addresses, specify the --enable-v4-mapped configure option.
    

    
    --enable-v4-mapped is the default on all platforms except
    FreeBSD, NetBSD, and OpenBSD, so this is probably how your httpd was
    built.
    

    
    If you want httpd to handle IPv4 connections only, regardless of
    what your platform and APR will support, specify an IPv4 address on all
    Listen directives, as in the
    following examples:
    

    
    Listen 0.0.0.0:80
Listen 192.0.2.1:80
    

    

    
    If your platform supports it and you want httpd to handle IPv4 and
    IPv6 connections on separate sockets (i.e., to disable IPv4-mapped
    addresses), specify the --disable-v4-mapped configure option. --disable-v4-mapped is the
    default on FreeBSD, NetBSD, and OpenBSD.
    
  
    top
    

    

    Specifying the protocol with Listen
    
    
    
    The optional second protocol argument of
       Listen
       is not required for most
       configurations. If not specified, https is the default for
       port 443 and http the default for all other ports.  The
       protocol is used to determine which module should handle a request, and
       to apply protocol specific optimizations with the
       AcceptFilter directive.
    

    
    You only need to set the protocol if you are running on non-standard
       ports.  For example, running an https site on port 8443:
    

    
    Listen 192.170.2.1:8443 https
    

    
  
    top
    

    

    How This Works With Virtual Hosts
    
    

    
     The Listen directive does not implement
    Virtual Hosts - it only tells the
    main server what addresses and ports to listen on. If no
    <VirtualHost>
    directives are used, the server will behave
    in the same way for all accepted requests. However,
    <VirtualHost>
    can be used to specify a different behavior
    for one or more of the addresses or ports. To implement a
    VirtualHost, the server must first be told to listen to the
    address and port to be used. Then a
    <VirtualHost> section
    should be created for the specified address and port to set the
    behavior of this virtual host. Note that if the
    <VirtualHost>
    is set for an address and port that the
    server is not listening to, it cannot be accessed.

    This document describes what a Multi-Processing Module is and
how they are used by the Apache HTTP Server.
    

    


    top
    

    

    Introduction
    

    
    The Apache HTTP Server is designed to be a powerful and
    flexible web server that can work on a very wide variety of
    platforms in a range of different environments. Different
    platforms and different environments often require different
    features, or may have different ways of implementing the same
    feature most efficiently. Apache httpd has always accommodated a wide
    variety of environments through its modular design. This design
    allows the webmaster to choose which features will be included
    in the server by selecting which modules to load either at
    compile-time or at run-time.
    

    
    Apache HTTP Server 2.0 extends this modular design to the most basic
    functions of a web server. The server ships with a selection of
    Multi-Processing Modules (MPMs) which are responsible for
    binding to network ports on the machine, accepting requests,
    and dispatching children to handle the requests.
    

    
    Extending the modular design to this level of the server
    allows two important benefits:
    

    
      
      
    • Apache httpd can more cleanly and efficiently support a wide
      variety of operating systems. In particular, the Windows
      version of the server is now much more efficient, since
      mpm_winnt can use native
      networking features in place of the POSIX layer used in
      Apache httpd 1.3. This benefit also extends to other operating
      systems that implement specialized MPMs.
      • 

      
    • The server can be better customized for the needs of the
      particular site. For example, sites that need a great deal of
      scalability can choose to use a threaded MPM like
      worker or event, while sites requiring
      stability or compatibility with older software can use a
      prefork.
      • 
    
    

    
    At the user level, MPMs appear much like other Apache httpd
    modules. The main difference is that one and only one MPM must
    be loaded into the server at any time. The list of available
    MPMs appears on the module index page.
    


    top
    

    

    MPM Defaults
    


    The following table lists the default MPMs for various operating
systems.  This will be the MPM selected if you do not make another
choice at compile-time.
    


    Netwarempm_netware
    

    OS/2mpmt_os2
    

    Unixprefork, worker, or
    event, depending on platform capabilities
    

    Windowsmpm_winnt
    

    


    Here, 'Unix' is used to mean Unix-like operating systems, such as
Linux, BSD, Solaris, Mac OS X, etc.
    


    In the case of Unix, the decision as to which MPM is installed is
based on two questions:
    

    1. Does the system support threads?
    

    2. Does the system support thread-safe polling (Specifically, the
kqueue and epoll functions)?
    


    If the answer to both questions is 'yes', the default MPM is
event.
    


    If The answer to #1 is 'yes', but the answer to #2 is 'no', the
default will be worker.
    


    If the answer to both questions is 'no', then the default MPM will be
prefork.
    


    In practical terms, this means that the default will almost always be
event, as all modern operating systems support these
two features.

    Building an MPM as a static module
    

    
    MPMs can be built as static modules on all platforms.  A single MPM
    is chosen at build time and linked into the server.  The server must
    be rebuilt in order to change the MPM.
    

    
    To override the default MPM choice, use the
    --with-mpm=NAME option of the
    configure script. NAME is the name of the
    desired MPM.
    

    
    Once the server has been compiled, it is possible to determine which MPM
    was chosen by using ./httpd -l. This command will list every
    module that is compiled into the server, including the MPM.
    


    top
    

    

    Building an MPM as a DSO module
    

    
    On Unix and similar platforms, MPMs can be built as DSO modules and
    dynamically loaded into the server in the same manner as other DSO
    modules.  Building MPMs as DSO modules allows the MPM to be changed by
    updating the LoadModule directive
    for the MPM instead of by rebuilding the server.
    

    
    LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
    


    
    Attempting to LoadModule
    more than one MPM will result in a startup failure with the
    following error.
    

    
    AH00534: httpd: Configuration error: More than one MPM
    loaded.
    

    
    This feature is enabled using the
    --enable-mpms-shared option of the configure
    script.
    With argument all, all possible MPMs for the platform
    will be installed.  Alternately, a list of MPMs can be specified as the
    argument.
    

    
    The default MPM, either selected automatically or specified with the
    --with-mpm option of the configure
    script, will be loaded in the generated server configuration file.  Edit the
    LoadModule directive to select a
    different MPM.

    この文書では、Apache HTTP サーババージョン 1.3 と 2.0
     の主な違いについて記述しています。
    

    


    top
    

    

    コア機能の拡張
    
    

    
    
      
    Unix のスレッド
    

      
    POSIX スレッドをサポートしている Unix システム上では、
      Apache はマルチプロセス、マルチスレッドのハイブリッドモードで
      実行できるようになりました。これにより
      多くの設定においてスケーラビリティが向上します。
    

      
    新しいビルドシステム
    

      
    ビルドシステムは autoconf と libtool
      に基づいたものになるように、
      新しく書き直されました。これにより、Apache の configure のシステムは
      他のパッケージと似たものになりました。
    

      
    マルチプロトコルサポート
    

      
    Apache に複数のプロトコルを扱うための機構が備わりました。
      例として mod_echo が書かれています。
    

      
    Unix 以外のプラットフォームのサポートの改善
    

      
    Apache 2.0 は BeOS、OS/2、Windows などの Unix 以外の
      プラットフォームで、より速く、より安定して動作するようになりました。
      プラットフォーム特有の マルチプロセッシングモジュール (MPM) と
      Apache Portable Runtime (APR) の導入により、
      ネイティヴの API で実装されるようになり、
      バグが多く、性能の悪いことが多い POSIX エミュレーションレイヤの使用を
      回避することができました。
    

      
    新しい Apache API
    

      
    2.0 ではモジュールの API が大きく変わりました。
      1.3 にあったモジュールの順番/優先度の問題の多くは
      なくなっているはずです。2.0 は優先度の選択をほとんどを自動的に行ない、
      モジュールの順番はより柔軟性を高めるためにフック毎に行なわれるように
      なりました。また、コア Apache サーバにパッチをあてることなく
      追加のモジュール機能を提供することができるように新しい関数が
      追加されました。
    

      
    IPv6 サポート
    

      
    Apache が使用している Apache Portable Runtime library が
      IPv6 をサポートしているシステムでは Apache は デフォルトで
      IPv6 のソケットを listen します。さらに、
      Listen,
      NameVirtualHost,
      VirtualHost
      の各ディレクティブが IPv6 のアドレスを
      サポートするようになりました (例えば、
      "Listen [2001:db8::1]:8080")。
    

      
    フィルタ
    

      
    Apache のモジュールはサーバから送られてきたり、サーバへ
      送るストリームに対して動作するフィルタとして書くことができるように
      なりました。これにより、例えば CGI スクリプトの出力を
      mod_include の INCLUDES フィルタを使って
      Server Side Include のディレクティブを解析する、
      というようなことが可能になりました。mod_ext_filter
      で外部プログラムをフィルタとして動作させることができます。
      これは CGI プログラムをハンドラとして動作させるのと
      よく似た方法でできます。
    

      
    多言語エラー応答
    

      
    ブラウザへのエラー応答のメッセージが、SSI の文書を使って
      複数の言語で提供されるようになりました。見ための一貫性を保つために
      管理者がカスタマイズすることもできます。
    

      
    設定の簡素化
    

      
    多くの混乱を招きがちなディレクティブが簡素化されました。
      よく混乱を引き起こしていた Port ディレクティブと 
      Bind ディレクティブは
      なくなりました。Listen
      ディレクティブのみが IP アドレスのバインドに使われます。
      ServerName ディレクティブでは
      リダイレクトと vhost の認識のためだけにサーバの名前とポート番号を
      指定します。
    

      
    Windows NT のネイティヴ Unicode サポート
    

      
    Windows NT 上の Apache 2.0 はファイル名の文字エンコード全てに
      utf-8 を使うようになりました。これらは Unicode ファイルシステムに
      直接変換されるので、Windows 2000 と Windows XP を含む、全ての
      Windows NT 系で多言語サポートが提供されます。
      このサポートは、ファイルシステムのアクセス時にローカルの
      コードページを使う Windows 95, 98, ME には適用されません。
    

      
    正規表現ライブラリのアップデート
    

      
    Apache 2.0 は Perl
      互換正規表現ライブラリ (PCRE) を含んでいます。
      正規表現の評価には、より強力になった Perl 5
      構文を使用します。
    

    
    
  
    top
    

    

    モジュールの拡張
    
    

    
    
      
    mod_ssl
    

      
    Apache 2.0 の新モジュール。このモジュールは OpenSSL が
      提供する SSL/TLS 暗号プロトコルへのインタフェースです。
    

      
    mod_dav
    

      
    Apache 2.0 の新モジュール。このモジュールはウェブコンテンツを
      送り、維持するための規格
      HTTP Distributed Authoring and Versioning (DAV) を実装しています。
    

      
    mod_deflate
    

      
    Apache 2.0 の新モジュール。送信前に送信内容を圧縮して
      ネットワーク帯域を節約する、というリクエストをブラウザが
      要求できるようにします。
    

      
    mod_auth_ldap
    

      
    Apache 2.0.41 の新モジュール。HTTP 基本認証の証明書を保存するのに、
      LDAP データベースを使用できるようになります。
      関連モジュールの mod_ldap で、
      コネクションのプール機能と結果のキャッシュ機能が提供されます。
    

      
    mod_auth_digest
    

      
    このモジュールは共有メモリを使うことにより、プロセスをまたいだ
      セッションのキャッシュをサポートするようになりました。
    

      
    mod_charset_lite
    

      
    Apache 2.0 の新モジュール。この実験的なモジュールは
      キャラクタセットの変換や再符号化を可能にします。
    

      
    mod_file_cache
    

      
    Apache 2.0 の新モジュール。このモジュールには、
      Apache 1.3 における mod_mmap_static 機能が含まれ、
      また、追加のキャッシュ機能が加わっています。
    

      
    mod_headers
    

      
    このモジュールは Apache 2.0 で非常に柔軟性が
      高くなりました。mod_proxy
      で使われるリクエストのヘッダを変更できるようになりましたし、
      応答ヘッダを条件に応じて設定できるようになりました。
    

      
    mod_proxy
    

      
    proxy モジュールは新しいフィルタの機構を利用するためと、
      より信頼できる、HTTP/1.1 に準拠した proxy を実装するために
      完全に書き直されました。さらに、新しい 
      <Proxy>
      設定セクションがproxy されるサイトのより読みやすく (内部的にもより速い)
      設定を提供します。オーバーロードされた
      <Directory "proxy:... >
      設定はサポートされていません。このモジュールは proxy_connect,
      proxy_ftp, proxy_http 
      といった、特定のプロトコルをサポートする
      モジュールに分割されるようになりました。
    

      
    mod_negotiation
    

      
    クライアントが NOT ACCEPTABLE や MULTIPLE CHOICES 応答の
      代わりに常に単独の文書を受けとるようにするために、新しいディレクティブ
      ForceLanguagePriority
      を使うことができるようになりました。
      さらに、より一貫性のある結果を提供するために
      ネゴシエーションと MultiViews のアルゴリズムが改善され、
      文書の内容を含めることのできる、新しい形式のタイプマップが
      提供されるようになりました。
    

      
    mod_autoindex
    

      
    Autoindex されるディレクトリの内容一覧が、
      きれいに表示されるために HTML のテーブルを使うように
      設定できるようになりました。また、バージョンによるソーティングなど、
      より細かいソーティングの制御ができるようになり、ディレクトリ
      の内容一覧をワイルドカードにより選別することができるようにもなりました。
    

      
    mod_include
    

      
    新しいディレクティブにより、SSI のデフォルトの開始タグと終了タグを
      変更できるようになりました。また、エラーと時刻の形式の設定が SSI の
      文書中ではなく、主設定ファイル中で行なえるようになりました。
      正規表現の解析とグループ化の結果 (Perl の正規表現の構文に
      基づいたものになりました) を mod_include
      の変数 $0 .. $9 により取得できるようになりました。
    

      
    mod_auth_dbm
    

      
    AuthDBMType
      ディレクティブにより、複数の DBM 型のデータベースをサポートする
      ようになりました。

    In order to effectively manage a web server, it is necessary
    to get feedback about the activity and performance of the
    server as well as any problems that may be occurring. The Apache HTTP Server
    provides very comprehensive and flexible logging
    capabilities. This document describes how to configure its
    logging capabilities, and how to understand what the logs
    contain.

    Overview
    
    

  
    Related ModulesRelated Directives
    

  
    
  The Apache HTTP Server provides a variety of different mechanisms for
  logging everything that happens on your server, from the initial
  request, through the URL mapping process, to the final resolution of
  the connection, including any errors that may have occurred in the
  process. In addition to this, third-party modules may provide logging
  capabilities, or inject entries into the existing log files, and
  applications such as CGI programs, or PHP scripts, or other handlers,
  may send messages to the server error log.
  
    

  
    
  In this document we discuss the logging modules that are a standard
  part of the http server.

    Security Warning
    
    

    
    Anyone who can write to the directory where Apache httpd is
    writing a log file can almost certainly gain access to the uid
    that the server is started as, which is normally root. Do
    NOT give people write access to the directory the logs
    are stored in without being aware of the consequences; see the
    security tips document
    for details.
    

    
    In addition, log files may contain information supplied
    directly by the client, without escaping. Therefore, it is
    possible for malicious clients to insert control-characters in
    the log files, so care must be taken in dealing with raw
    logs.

    Error Log
    
    

    
    Related ModulesRelated Directives
    

    
    The server error log, whose name and location is set by the
    ErrorLog directive, is the
    most important log file. This is the place where Apache httpd
    will send diagnostic information and record any errors that it
    encounters in processing requests. It is the first place to
    look when a problem occurs with starting the server or with the
    operation of the server, since it will often contain details of
    what went wrong and how to fix it.
    

    
    The error log is usually written to a file (typically
    error_log on Unix systems and
    error.log on Windows and OS/2). On Unix systems it
    is also possible to have the server send errors to
    syslog or pipe them to a
    program.
    

    
    The format of the error log is defined by the ErrorLogFormat directive, with which you
    can customize what values are logged. A default is format defined
    if you don't specify one. A typical log message follows:
    

    
    
    [Fri Sep 09 10:42:29.902022 2011] [core:error] [pid 35708:tid 4328636416]
    [client 72.15.99.187] File does not exist: /usr/local/apache2/htdocs/favicon.ico
    
    

    
    The first item in the log entry is the date and time of the
    message. The next is the module producing the message (core, in this
    case) and the severity level of that message. This is followed by
    the process ID and, if appropriate, the thread ID, of the process
    that experienced the condition. Next, we have the client address
    that made the request. And finally is the detailed error message,
    which in this case indicates a request for a file that did not
    exist.
    

    
    A very wide variety of different messages can appear in the
    error log. Most look similar to the example above. The error
    log will also contain debugging output from CGI scripts. Any
    information written to stderr by a CGI script will
    be copied directly to the error log.
    

    
    Putting a %L token in both the error log and the access
    log will produce a log entry ID with which you can correlate the entry
    in the error log with the entry in the access log. If
    mod_unique_id is loaded, its unique request ID will be
    used as the log entry ID, too.
    

    
    During testing, it is often useful to continuously monitor
    the error log for any problems. On Unix systems, you can
    accomplish this using:
    

    
    
      tail -f error_log
    
    
  
    top
    

    

    Per-module logging
    
    

    
    The LogLevel directive
    allows you to specify a log severity level on a per-module basis. In
    this way, if you are troubleshooting a problem with just one
    particular module, you can turn up its logging volume without also
    getting the details of other modules that you're not interested in.
    This is particularly useful for modules such as
    mod_proxy or mod_rewrite where you
    want to know details about what it's trying to do.
    

    
    Do this by specifying the name of the module in your
    LogLevel directive:
    

    
    LogLevel info rewrite:trace5
    


    
    This sets the main LogLevel to info, but
    turns it up to trace5 for
    mod_rewrite.
    

    
    This replaces the per-module logging directives, such as
    RewriteLog, that were present in earlier versions of
    the server.

    Access Log
    
    

    
    Related ModulesRelated Directives
    

    
    The server access log records all requests processed by the
    server. The location and content of the access log are
    controlled by the CustomLog
    directive. The LogFormat
    directive can be used to simplify the selection of
    the contents of the logs. This section describes how to configure the server
    to record information in the access log.
    

    
    Of course, storing the information in the access log is only
    the start of log management. The next step is to analyze this
    information to produce useful statistics. Log analysis in
    general is beyond the scope of this document, and not really
    part of the job of the web server itself. For more information
    about this topic, and for applications which perform log
    analysis, check the 
    Open Directory.
    
    

    
    Various versions of Apache httpd have used other modules and
    directives to control access logging, including
    mod_log_referer, mod_log_agent, and the
    TransferLog directive. The CustomLog directive now subsumes
    the functionality of all the older directives.
    

    
    The format of the access log is highly configurable. The format
    is specified using a format string that looks much like a C-style
    printf(1) format string. Some examples are presented in the next
    sections. For a complete list of the possible contents of the
    format string, see the mod_log_config format strings.
    

    
    Common Log Format
    
      

      
    A typical configuration for the access log might look as
      follows.
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog logs/access_log common
    


      
    This defines the nickname common and
      associates it with a particular log format string. The format
      string consists of percent directives, each of which tell the
      server to log a particular piece of information. Literal
      characters may also be placed in the format string and will be
      copied directly into the log output. The quote character
      (") must be escaped by placing a backslash before
      it to prevent it from being interpreted as the end of the
      format string. The format string may also contain the special
      control characters "\n" for new-line and
      "\t" for tab.
    

      
    The CustomLog
      directive sets up a new log file using the defined
      nickname. The filename for the access log is relative to
      the ServerRoot unless it
      begins with a slash.
    

      
    The above configuration will write log entries in a format
      known as the Common Log Format (CLF). This standard format can
      be produced by many different web servers and read by many log
      analysis programs. The log file entries produced in CLF will
      look something like this:
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
      
    

      
    Each part of this log entry is described below.
    

      
    
        
    127.0.0.1 (%h)
    

        
    This is the IP address of the client (remote host) which
        made the request to the server. If HostnameLookups is
        set to On, then the server will try to determine
        the hostname and log it in place of the IP address. However,
        this configuration is not recommended since it can
        significantly slow the server. Instead, it is best to use a
        log post-processor such as logresolve to determine
        the hostnames. The IP address reported here is not
        necessarily the address of the machine at which the user is
        sitting. If a proxy server exists between the user and the
        server, this address will be the address of the proxy, rather
        than the originating machine.
    

        
    - (%l)
    

        
    The "hyphen" in the output indicates that the requested
        piece of information is not available. In this case, the
        information that is not available is the RFC 1413 identity of
        the client determined by identd on the clients
        machine. This information is highly unreliable and should
        almost never be used except on tightly controlled internal
        networks. Apache httpd will not even attempt to determine
        this information unless IdentityCheck is set
        to On.
    

        
    frank (%u)
    

        
    This is the userid of the person requesting the document
        as determined by HTTP authentication. The same value is
        typically provided to CGI scripts in the
        REMOTE_USER environment variable. If the status
        code for the request (see below) is 401, then this value
        should not be trusted because the user is not yet
        authenticated. If the document is not password protected,
        this part will be "-" just like the previous
        one.
    

        
    [10/Oct/2000:13:55:36 -0700]
        (%t)
    

        
    
          The time that the request was received.
          The format is:

          
    
            [day/month/year:hour:minute:second zone]
    
             day = 2*digit
    
             month = 3*letter
    
             year = 4*digit
    
             hour = 2*digit
    
             minute = 2*digit
    
             second = 2*digit
    
             zone = (`+' | `-') 4*digit    
          
    
          
    It is possible to have the time displayed in another format
          by specifying %{format}t in the log format
          string, where format is either as in
          strftime(3) from the C standard library,
          or one of the supported special tokens. For details see
          the mod_log_config format strings.
    
        
    

        
    "GET /apache_pb.gif HTTP/1.0"
        (\"%r\")
    

        
    The request line from the client is given in double
        quotes. The request line contains a great deal of useful
        information. First, the method used by the client is
        GET. Second, the client requested the resource
        /apache_pb.gif, and third, the client used the
        protocol HTTP/1.0. It is also possible to log
        one or more parts of the request line independently. For
        example, the format string "%m %U%q %H" will log
        the method, path, query-string, and protocol, resulting in
        exactly the same output as "%r".
    

        
    200 (%>s)
    

        
    This is the status code that the server sends back to the
        client. This information is very valuable, because it reveals
        whether the request resulted in a successful response (codes
        beginning in 2), a redirection (codes beginning in 3), an
        error caused by the client (codes beginning in 4), or an
        error in the server (codes beginning in 5). The full list of
        possible status codes can be found in the HTTP
        specification (RFC2616 section 10).
    

        
    2326 (%b)
    

        
    The last part indicates the size of the object returned
        to the client, not including the response headers. If no
        content was returned to the client, this value will be
        "-". To log "0" for no content, use
        %B instead.
    
      
    
    

    
    Combined Log Format
    
      

      
    Another commonly used format string is called the Combined
      Log Format. It can be used as follows.
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined
CustomLog log/access_log combined
    


      
    This format is exactly the same as the Common Log Format,
      with the addition of two more fields. Each of the additional
      fields uses the percent-directive
      %{header}i, where header can be
      any HTTP request header. The access log under this format will
      look like:
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
        "http://www.example.com/start.html" "Mozilla/4.08 [en]
        (Win98; I ;Nav)"
      
    

      
    The additional fields are:
    

      
    
        
    "http://www.example.com/start.html"
        (\"%{Referer}i\")
    

        
    The "Referer" (sic) HTTP request header. This gives the
        site that the client reports having been referred from. (This
        should be the page that links to or includes
        /apache_pb.gif).
    

        
    "Mozilla/4.08 [en] (Win98; I ;Nav)"
        (\"%{User-agent}i\")
    

        
    The User-Agent HTTP request header. This is the
        identifying information that the client browser reports about
        itself.
    
      
    
    

    
    Multiple Access Logs
    
      

      
    Multiple access logs can be created simply by specifying
      multiple CustomLog
      directives in the configuration
      file. For example, the following directives will create three
      access logs. The first contains the basic CLF information,
      while the second and third contain referer and browser
      information. The last two CustomLog lines show how
      to mimic the effects of the ReferLog and AgentLog directives.
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog logs/access_log common
CustomLog logs/referer_log "%{Referer}i -> %U"
CustomLog logs/agent_log "%{User-agent}i"
    


      
    This example also shows that it is not necessary to define a
      nickname with the LogFormat directive. Instead,
      the log format can be specified directly in the CustomLog directive.
    
    

    
    Conditional Logs
    
      

      
    There are times when it is convenient to exclude certain
      entries from the access logs based on characteristics of the
      client request. This is easily accomplished with the help of environment variables. First, an
      environment variable must be set to indicate that the request
      meets certain conditions. This is usually accomplished with
      SetEnvIf. Then the
      env= clause of the CustomLog directive is used to
      include or exclude requests where the environment variable is
      set. Some examples:
    

      
    # Mark requests from the loop-back interface
SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog
# Mark requests for the robots.txt file
SetEnvIf Request_URI "^/robots\.txt$" dontlog
# Log what remains
CustomLog logs/access_log common env=!dontlog
    


      
    As another example, consider logging requests from
      english-speakers to one log file, and non-english speakers to a
      different log file.
    

      
    SetEnvIf Accept-Language "en" english
CustomLog logs/english_log common env=english
CustomLog logs/non_english_log common env=!english
    


      
    In a caching scenario one would want to know about
      the efficiency of the cache. A very simple method to
      find this out would be:
    

      
    SetEnv CACHE_MISS 1
LogFormat "%h %l %u %t "%r " %>s %b %{CACHE_MISS}e" common-cache
CustomLog logs/access_log common-cache
    


      
    mod_cache will run before
      mod_env and, when successful, will deliver the
      content without it. In that case a cache hit will log
      -, while a cache miss will log 1.
    

      
    In addition to the env= syntax, LogFormat supports logging values
      conditional upon the HTTP response code:
    

      
    LogFormat "%400,501{User-agent}i" browserlog
LogFormat "%!200,304,302{Referer}i" refererlog
    


      
    In the first example, the User-agent will be
      logged if the HTTP status code is 400 or 501. In other cases, a
      literal "-" will be logged instead. Likewise, in the second
      example, the Referer will be logged if the HTTP
      status code is not 200, 204, or 302. (Note the
      "!" before the status codes.
    

      
    Although we have just shown that conditional logging is very
      powerful and flexible, it is not the only way to control the
      contents of the logs. Log files are more useful when they
      contain a complete record of server activity. It is often
      easier to simply post-process the log files to remove requests
      that you do not want to consider.

    Log Rotation
    
    

    
    On even a moderately busy server, the quantity of
    information stored in the log files is very large. The access
    log file typically grows 1 MB or more per 10,000 requests. It
    will consequently be necessary to periodically rotate the log
    files by moving or deleting the existing logs. This cannot be
    done while the server is running, because Apache httpd will continue
    writing to the old log file as long as it holds the file open.
    Instead, the server must be restarted after the log files are
    moved or deleted so that it will open new log files.
    

    
    By using a graceful restart, the server can be
    instructed to open new log files without losing any existing or
    pending connections from clients. However, in order to
    accomplish this, the server must continue to write to the old
    log files while it finishes serving old requests. It is
    therefore necessary to wait for some time after the restart
    before doing any processing on the log files. A typical
    scenario that simply rotates the logs and compresses the old
    logs to save space is:
    

    
    
      mv access_log access_log.old
    
      mv error_log error_log.old
    
      apachectl graceful
    
      sleep 600
    
      gzip access_log.old error_log.old
    
    

    
    Another way to perform log rotation is using piped logs as discussed in the next
    section.
    
  
    top
    

    

    Piped Logs
    
    

    
    Apache httpd is capable of writing error and access log
    files through a pipe to another process, rather than directly
    to a file. This capability dramatically increases the
    flexibility of logging, without adding code to the main server.
    In order to write logs to a pipe, simply replace the filename
    with the pipe character "|", followed by the name
    of the executable which should accept log entries on its
    standard input. The server will start the piped-log process when
    the server starts, and will restart it if it crashes while the
    server is running. (This last feature is why we can refer to
    this technique as "reliable piped logging".)
    

    
    Piped log processes are spawned by the parent Apache httpd
    process, and inherit the userid of that process. This means
    that piped log programs usually run as root. It is therefore
    very important to keep the programs simple and secure.
    

    
    One important use of piped logs is to allow log rotation
    without having to restart the server. The Apache HTTP Server
    includes a simple program called rotatelogs
    for this purpose. For example, to rotate the logs every 24 hours, you
    can use:
    

    
    CustomLog "|/usr/local/apache/bin/rotatelogs /var/log/access_log 86400" common
    


    
    Notice that quotes are used to enclose the entire command
    that will be called for the pipe. Although these examples are
    for the access log, the same technique can be used for the
    error log.
    

    
    As with conditional logging, piped logs are a very powerful
    tool, but they should not be used where a simpler solution like
    off-line post-processing is available.
    

    
    By default the piped log process is spawned without invoking
    a shell. Use "|$" instead of "|"
    to spawn using a shell (usually with /bin/sh -c):
    

    
    # Invoke "rotatelogs" using a shell
CustomLog "|$/usr/local/apache/bin/rotatelogs   /var/log/access_log 86400" common
    


    
    This was the default behaviour for Apache 2.2.
    Depending on the shell specifics this might lead to
    an additional shell process for the lifetime of the logging
    pipe program and signal handling problems during restart.
    For compatibility reasons with Apache 2.2 the notation
    "||" is also supported and equivalent to using
    "|".
    

    
    Windows note
    
    
    Note that on Windows, you may run into problems when running many piped
    logger processes, especially when HTTPD is running as a service. This is
    caused by running out of desktop heap space. The desktop heap space given
    to each service is specified by the third argument to the
    SharedSection parameter in the
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\SubSystems\Windows
    registry value. Change this value with care; the normal
    caveats for changing the Windows registry apply, but you might also exhaust
    the desktop heap pool if the number is adjusted too high.

    Virtual Hosts
    
    

    
    When running a server with many virtual
    hosts, there are several options for dealing with log
    files. First, it is possible to use logs exactly as in a
    single-host server. Simply by placing the logging directives
    outside the <VirtualHost> sections in the
    main server context, it is possible to log all requests in the
    same access log and error log. This technique does not allow
    for easy collection of statistics on individual virtual
    hosts.
    

    
    If CustomLog
    or ErrorLog
    directives are placed inside a
    <VirtualHost>
    section, all requests or errors for that virtual host will be
    logged only to the specified file. Any virtual host which does
    not have logging directives will still have its requests sent
    to the main server logs. This technique is very useful for a
    small number of virtual hosts, but if the number of hosts is
    very large, it can be complicated to manage. In addition, it
    can often create problems with insufficient file
    descriptors.
    

    
    For the access log, there is a very good compromise. By
    adding information on the virtual host to the log format
    string, it is possible to log all hosts to the same log, and
    later split the log into individual files. For example,
    consider the following directives.
    

    
    LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost
CustomLog logs/access_log comonvhost
    


    
    The %v is used to log the name of the virtual
    host that is serving the request. Then a program like split-logfile can be used to
    post-process the access log in order to split it into one file
    per virtual host.

    Logging actual bytes sent and received
    
      

      
    mod_logio adds in two additional
         LogFormat fields
         (%I and %O) that log the actual number of bytes received and sent
         on the network.
    
    

    
    Forensic Logging
    
      

      
    mod_log_forensic provides for forensic logging of
         client requests. Logging is done before and after processing a
         request, so the forensic log contains two log lines for each
         request. The forensic logger is very strict with no customizations.
         It can be an invaluable debugging and security tool.
    
    

    
    PID File
    
      

      
    On startup, Apache httpd saves the process id of the parent
      httpd process to the file logs/httpd.pid. This
      filename can be changed with the PidFile directive. The
      process-id is for use by the administrator in restarting and
      terminating the daemon by sending signals to the parent
      process; on Windows, use the -k command line option instead.
      For more information see the Stopping
      and Restarting page.
    
    

    
    Script Log
    
      

      
    In order to aid in debugging, the
      ScriptLog directive
      allows you to record the input to and output from CGI scripts.
      This should only be used in testing - not for live servers.
      More information is available in the mod_cgi documentation.

    Este documento describe que es un Módulo de Multiprocesamiento y
como los usa Apache.
    

    


    top
    

    

    Introducción
    

    
    Apache está diseñado para ser un servidor web potente
    y flexible que pueda funcionar en la más amplia variedad de
    plataformas y entornos. Las diferentes plataformas y los
    diferentes entornos, hacen que a menudo sean necesarias diferentes
    características o funcionalidades, o que una misma
    característica o funcionalidad sea implementada de diferente
    manera para obtener una mayor eficiencia. Apache se ha adaptado
    siempre a una gran variedad de entornos a través de su
    diseño modular. Este diseño permite a los
    administradores de sitios web elegir que características van
    a ser incluidas en el servidor seleccionando que módulos se
    van a cargar, ya sea al compilar o en tiempo de ejecución.
    

    
    Apache 2.0 extiende este diseño modular hasta las
    funciones más básicas de un servidor web. El servidor
    viene con una serie de Módulos de MultiProcesamiento que son
    responsables de conectar con los puertos de red de la
    máquina, aceptar las peticiones, y generar los procesos hijo
    que se encargan de servirlas.
    

    
    La extensión del diseño modular a este nivel del
    servidor ofrece dos beneficios importantes:
    

    
      
      
    • Apache puede soportar de una forma más fácil y
      eficiente una amplia variedad de sistemas operativos. En
      concreto, la versión de Windows de Apache es mucho más
      eficiente, porque el módulo mpm_winnt
      puede usar funcionalidades nativas de red en lugar de usar la
      capa POSIX como hace Apache 1.3. Este beneficio se extiende
      también a otros sistemas operativos que implementan sus
      respectivos MPMs.
      • 

      
    • El servidor puede personalizarse mejor para las necesidades
      de cada sitio web. Por ejemplo, los sitios web que necesitan
      más que nada escalabilidad pueden usar un proceso MPM como
      worker, mientras que los sitios web que
      requieran por encima de otras cosas estabilidad o compatibilidad
      con software antiguo pueden usar
      prefork.
      
      • 
    
    

    
    A nivel de usuario, los MPMs son como cualquier otro
    módulo de Apache. La diferencia más importante es que
    solo un MPM puede estar cargado en el servidor en un determinado
    momento. La lista de MPMs disponibles está en la sección índice de Módulos.
    


    top
    

    

    MPM por defecto
    


    En la siguiente tabla se muestran los MPMs por defecto para varios
sistemas operativos.  Estos serán los MPM seleccionados si no se
especifica lo contrario al compilar.
    


    Netwarempm_netware
    

    OS/2mpmt_os2
    

    Unixprefork, worker, or
    event, depending on platform capabilities
    

    Windowsmpm_winnt
    

    


    aquí, 'Unix' se usa para designar a los sistemas operativos "Unix-like", como
Linux, BSD, Solaris, Mac OS X, etc.
    


    En el caso de los Unix, la decisión de que MPM se va a instalar
  depende de dos pregunas:
    

    1. ¿Nos permite el Sistema Operativo hilos?
    

    2. -¿Nos permite el sistema operativo soporte a pila de hilos seguros 
  (Especificamente, las funciones kqueue y epoll)?

    Le cache des objets partagés du serveur HTTP Apache
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    
    Le cache des objets partagés est un concept de partage de données
    de base entre tous les processus d'un serveur, sans se préoccuper du
    modèle de threads et de processus. On
    l'utilise lorsque les avantages apportés par le partage de données
    entre processus contrebalance la perte de performances consécutive à
    la communication interprocessus.
    
  
    

    top
    

    

    Fournisseurs du cache d'objets partagés
    
    
    
    Le cache d'objets partagés en tant que tel est une abstraction.
    Il est implémenté par cinq modules différents. Pour pouvoir
    utiliser le cache, un ou plusieurs de ces modules doivent être
    présents et configurés.
    
    
    Le seul élément de configuration consiste à définir le
    fournisseur de cache à utiliser. Ceci est de la responsabilité des
    modules qui utilisent le cache, et pour cela, ils activent la
    sélection via des directives telles que CacheSocache, AuthnCacheSOCache, SSLSessionCache, et SSLStaplingCache.
    
    
    Les fournisseurs actuellement disponibles sont :
    
    
    
    
    "dbm" (mod_socache_dbm)
    
    
    Celui-ci utilise un fichier de hashage DBM. Le choix de la
    DBM sous-jacente peut être configurable si la version
    d'APR installée supporte de multiples implémentations de DBM.
    
    
    "dc" (mod_socache_dc)
    
    
    Celui-ci utilise les bibliothèques de mise en cache de sessions
    distribuées distcache.
    
    
    "memcache" (mod_socache_memcache)
    
    
    Celui-ci utilise le système à hautes performances de mise en
    cache d'objets de mémoire distribuée memcached.
    
    
    "redis" (mod_socache_redis)
    
    
    Celui-ci utilise le système de mise en cache d'objets de mémoire
    distribuée à hautes performances Redis.
    
    
    "shmcb" (mod_socache_shmcb)
    
    
    Celui-ci utilise un tampon cyclique à hautes performances au
    sein d'un segment de mémoire partagée.
    
    
    

    
    L'API fournit les fonctions suivantes :
    

    
    
      
    const char *create(ap_socache_instance_t **instance, const char *arg,
                          apr_pool_t *tmp, apr_pool_t *p);
    
      
    Cette fonction permet de créer un cache de session basé sur
      la chaîne de configuration spécifiée. Le pointeur d'instance
      renvoyé dans le paramètre instance sera passé comme premier
      argument des invocations subséquentes.
    

      
    apr_status_t init(ap_socache_instance_t *instance, const char *cname,
                         const struct ap_socache_hints *hints,
                         server_rec *s, apr_pool_t *pool)
    
      
    Cette fonction permet d'initialiser le cache. L'argument cname
      doit avoir une longueur maximale de 16 caractères et permet
      d'identifier de manière unique l'utilisateur du cache au sein du
      serveur ; il est recommandé d'utiliser le nom du module, par
      exemple "mod_ssl-sess". Comme cette chaîne peut être utilisée au
      sein d'un système de fichiers, il est conseillé de n'utiliser que
      des caractères alphanumériques [a-z0-9_-]. Si l'argument hints
      n'est pas égal à NULL, il fournit un ensemble d'indications au
      fournisseur. La valeur retournée est le code d'erreur APR.
    

      
    void destroy(ap_socache_instance_t *instance, server_rec *s)
    
      
    Cette fonction permet de détruire l'instance de cache
      spécifiée.
    

      
    apr_status_t store(ap_socache_instance_t *instance, server_rec *s,
                          const unsigned char *id, unsigned int idlen,
                          apr_time_t expiry,
                          unsigned char *data, unsigned int datalen,
                          apr_pool_t *pool)
    
      
    Cette fonction permet de stocker un objet dans une instance de
      cache.
    

      
    apr_status_t retrieve(ap_socache_instance_t *instance, server_rec *s,
                             const unsigned char *id, unsigned int idlen,
                             unsigned char *data, unsigned int *datalen,
                             apr_pool_t *pool)
    
      
    Cette fonction permet d'extraire un objet du cache.
    

      
    apr_status_t remove(ap_socache_instance_t *instance, server_rec *s,
                           const unsigned char *id, unsigned int idlen,
                           apr_pool_t *pool)
    
      
    Supprime un objet du cache.
    

      
    void status(ap_socache_instance_t *instance, request_rec *r, int flags)
    
      
    Renvoie le statut d'une instance de cache à destination de mod_status.
    

      
    apr_status_t iterate(ap_socache_instance_t *instance, server_rec *s,
                            void *userctx, ap_socache_iterator_t *iterator,
                            apr_pool_t *pool)
    
      
    Envoie tous les objets gardés en cache à une fonction pour traitement itératif.

    Ce document explique comment le serveur HTTP Apache utilise l'URL contenue dans une
    requête pour déterminer le noeud du système de fichier à partir duquel le
    fichier devra être servi.

    Racine des documents (DocumentRoot)
    

    
    La méthode par défaut de httpd pour déterminer quel fichier servir pour
    une requête donnée, consiste à extraire le chemin du fichier de la requête
    (la partie de l'URL qui suit le nom d'hôte et le port), puis de l'ajouter
    à la fin de la valeur de la directive
    DocumentRoot définie dans vos fichiers
    de configuration.
    Ainsi, les fichiers et répertoires
    situés en dessous de DocumentRoot
    constituent l'arborescence de base des documents qui seront visibles
    depuis le web.
    

    
    Par exemple, si la directive
    DocumentRoot contient
    /var/www/html, une requête pour
    http://www.example.com/fish/guppies.html retournera le
    fichier /var/www/html/fish/guppies.html au client.
    

    
    Si la requête concerne un répertoire (autrement dit un chemin se
    terminant par un slash /), le nom du fichier qui sera
    recherché et servi depuis ce répertoire est défini via la directive
    DirectoryIndex. Par exemple,
    supposons que DocumentRoot ait été définie comme
    précédemment, et que vous ayez défini DirectoryIndex
    comme suit :
    

    
    DirectoryIndex index.html index.php
    

    
    Si httpd reçoit alors une requête pour
    http://www.example.com/fish/, il tentera de servir le
    fichier /var/www/html/fish/index.html. Si ce fichier
    n'existe pas, il tentera de servir le fichier
    /var/www/html/fish/index.php.
    

    
    Si aucun de ces fichiers existe, httpd tentera de générer et
    d'afficher un index du répertoire, à condition que
    mod_autoindex ait été chargé et configuré pour le
    permettre.
    

    
    httpd supporte aussi les Hôtes virtuels,
    ce qui lui permet de traiter des requêtes pour plusieurs hôtes.
    Dans ce cas, un DocumentRoot
    différent peut être défini pour chaque hôte virtuel;
    les directives fournies par le module
    mod_vhost_alias peuvent aussi être utilisées afin de
    déterminer dynamiquement le noeud approprié du système de fichiers
    à partir duquel servir un contenu en fonction de l'adresse IP
    ou du nom d'hôte.
    

    
    La directive DocumentRoot  est
    définie dans le fichier de configuration de votre serveur principal
    (httpd.conf), mais peut aussi être redéfinie pour chaque
    Hôte virtuel supplémentaire que vous avez créé.
    

    top
    

    

    Fichiers situés en dehors de
l'arborescence DocumentRoot
    

    
    Il existe de nombreuses circonstances pour lesquelles il est nécessaire
    d'autoriser l'accès web à des portions du système de fichiers qui ne se
    trouvent pas dans l'arborescence DocumentRoot.  httpd propose de nombreuses
    solutions pour réaliser cela. Sur les systèmes Unix, les liens
    symboliques permettent de rattacher d'autres portions du système de
    fichiers au DocumentRoot. Pour des raisons de sécurité,
    httpd ne suivra les liens symboliques que si les Options pour le répertoire concerné contiennent
    FollowSymLinks ou SymLinksIfOwnerMatch.
    

    
    Une autre méthode consiste à utiliser la directive Alias pour rattacher toute portion
    du système de fichiers à l'arborescence du site web. Par exemple, avec
    


    Alias "/docs" "/var/web"
    


    
    l'URL http://www.example.com/docs/dir/file.html
    correspondra au fichier /var/web/dir/file.html. La
    directive
    ScriptAlias
    fonctionne de la même manière, excepté que tout contenu localisé dans le
    chemin cible sera traité comme un script CGI.
    

    
    Pour les situations qui nécessitent plus de flexibilité, vous disposez
    des directives AliasMatch
    et ScriptAliasMatch
    qui permettent des substitutions et comparaisons puissantes basées
    sur les expressions rationnelles.
    Par exemple,
    


    ScriptAliasMatch "^/~([a-zA-Z0-9]+)/cgi-bin/(.+)" "/home/$1/cgi-bin/$2"
    


    
    fera correspondre une requête du style
    http://example.com/~user/cgi-bin/script.cgi au chemin
    /home/user/cgi-bin/script.cgi, et traitera le fichier résultant
    comme un script CGI.
    

    top
    

    

    Répertoires des utilisateurs
    

    
    Sur les systèmes Unix, on peut traditionnellement faire référence
    au répertoire personnel d'un utilisateur particulier à l'aide de
    l'expression ~user/.
    Le module mod_userdir
    étend cette idée au web en autorisant l'accès aux fichiers situés dans les
    répertoires home des utilisateurs à l'aide d'URLs
    comme dans ce qui suit :
    


    http://www.example.com/~user/file.html
    

    
    Pour des raisons de sécurité, il est déconseillé de permettre un accès
    direct à un répertoire home d'utilisateur depuis le web. A cet effet, la
    directive UserDir
    spécifie un répertoire où sont situés les fichiers accessibles depuis le web
    dans le répertoire home de l'utilisateur.
    Avec la configuration par défaut
    Userdir public_html, l'URL ci-dessus correspondra à un fichier
    dont le chemin sera du style
    /home/user/public_html/file.html où
    /home/user/ est le répertoire home de l'utilisateur tel qu'il
    est défini dans /etc/passwd.
    

    
    La directive Userdir met à votre disposition de nombreuses
    formes différentes pour les systèmes où /etc/passwd ne
    spécifie pas la localisation du répertoire home.
    

    
    Certains jugent le symbole "~" (dont le code sur le web est souvent
    %7e) inapproprié et préfèrent utiliser une chaîne de
    caractères différente pour représenter les répertoires utilisateurs.
    mod_userdir ne supporte pas cette fonctionnalité. Cependant, si les
    répertoires home des utilisateurs sont structurés de manière rationnelle,
    il est possible d'utiliser la directive
    AliasMatch
    pour obtenir l'effet désiré. Par exemple, pour faire correspondre
    http://www.example.com/upages/user/file.html à
    /home/user/public_html/file.html, utilisez la directive
    AliasMatch suivante :
    


    AliasMatch "^/upages/([a-zA-Z0-9]+)(/(.*))?$"   "/home/$1/public_html/$3"
    


    top
    

    

    Redirection d'URL
    

    
    Les directives de configuration décrites dans les sections précédentes
    demandent à httpd d'extraire un contenu depuis un emplacement spécifique
    du système de fichiers
    et de la retourner au client. Il est cependant parfois
    souhaitable d'informer le
    client que le contenu demandé est localisé à une URL différente, et de
    demander au client d'élaborer une nouvelle requête avec la nouvelle URL.
    Ce processus se nomme redirection et est implémenté par la
    directive Redirect.
    Par exemple, si le contenu du répertoire /foo/ sous
    DocumentRoot est déplacé vers le
    nouveau répertoire /bar/, vous pouvez demander aux clients
    de le requérir à sa nouvelle localisation comme suit :
    


    Redirect permanent "/foo/"   "http://www.example.com/bar/"
    


    
    Ceci aura pour effet de rediriger tout chemin d'URL commençant par
    /foo/ vers le même chemin d'URL sur le serveur
    www.example.com en remplaçant /foo/ par
    /bar/. Vous pouvez rediriger les clients non seulement sur le
    serveur d'origine, mais aussi vers n'importe quel autre serveur.
    

    
    httpd propose aussi la directive RedirectMatch pour traiter les problèmes
    de réécriture d'une plus grande complexité. Par exemple, afin de rediriger
    les requêtes pour la page d'accueil du site vers un site différent, mais
    laisser toutes les autres requêtes inchangées, utilisez la
    configuration suivante :
    


    RedirectMatch permanent "^/$"    "http://www.example.com/startpage.html"
    


    
    De même, pour rediriger temporairement toutes les pages d'un site
    vers une page particulière d'un autre site, utilisez ce qui suit :
    


    RedirectMatch temp ".*"  "http://othersite.example.com/startpage.html"
    


    top
    

    

    Mandataire inverse (Reverse Proxy)
    


    httpd vous permet aussi de rapatrier des documents distants
dans l'espace des URL du serveur local.
Cette technique est appelée mandataire inverse ou reverse
proxying car le serveur web agit comme un serveur mandataire en
rapatriant les documents depuis un serveur distant puis les renvoyant
au client. Ceci diffère d'un service de mandataire usuel (direct) car, pour le client,
les documents semblent appartenir au serveur mandataire inverse.
    


    Dans l'exemple suivant, quand les clients demandent des documents situés
dans le répertoire
/foo/, le serveur rapatrie ces documents depuis le répertoire
/bar/ sur internal.example.com
et les renvoie au client comme s'ils appartenaient au serveur local.
    


    ProxyPass "/foo/" "http://internal.example.com/bar/"
ProxyPassReverse "/foo/" "http://internal.example.com/bar/"
ProxyPassReverseCookieDomain internal.example.com public.example.com
ProxyPassReverseCookiePath "/foo/" "/bar/"
    



    La directive ProxyPass configure
le serveur pour rapatrier les documents appropriés, alors que la directive
ProxyPassReverse
réécrit les redirections provenant de
internal.example.com de telle manière qu'elles ciblent le
répertoire approprié sur le serveur local. De manière similaire, les directives
ProxyPassReverseCookieDomain
et ProxyPassReverseCookiePath
réécrivent les cookies élaborés par le serveur d'arrière-plan.
    

    Il est important de noter cependant, que les liens situés dans les documents
ne seront pas réécrits.  Ainsi, tout lien absolu sur
internal.example.com fera décrocher le client
du serveur mandataire et effectuer sa requête directement sur
internal.example.com. Vous pouvez modifier ces liens (et
d'utres contenus) situés dans la page au moment où elle est envoyée au
client en utilisant le module mod_substitute.
    


    Substitute "s/internal\.example\.com/www.example.com/i"
    



    Le module mod_proxy_html rend possible une réécriture plus
élaborée des liens en HTML et XHTML. Il permet de créer des listes
d'URLs et de leurs réécritures, de façon à pouvoir gérer des scénarios
de réécriture complexes.
    

    top
    

    

    Moteur de réécriture
    

    
    Le moteur de réécriture mod_rewrite peut s'avérer
    utile lorsqu'une substitution plus puissante est nécessaire.
    Les directives fournies par ce module peuvent utiliser des caractéristiques de la
    requête comme le type de navigateur ou l'adresse IP source afin de décider
    depuis où servir le contenu. En outre, mod_rewrite peut utiliser des
    fichiers ou programmes de bases de données externes pour déterminer comment
    traiter une requête. Le moteur de réécriture peut effectuer les trois types
    de mise en correspondance discutés plus haut :
    redirections internes (aliases), redirections externes, et services mandataires.
    De nombreux exemples pratiques utilisant mod_rewrite sont discutés dans la
    documentation détaillée de mod_rewrite.
    

    top
    

    

    Fichier non trouvé (File Not Found)
    

    
    Inévitablement, apparaîtront des URLs qui ne correspondront à aucun
    fichier du système de fichiers.
    Ceci peut arriver pour de nombreuses raisons.
    Il peut s'agir du déplacement de documents d'une
    localisation vers une autre. Dans ce cas, le mieux est d'utiliser la
    redirection d'URL pour informer les clients de la
    nouvelle localisation de la ressource. De cette façon, vous êtes sur que
    les anciens signets et liens continueront de fonctionner, même si la
    ressource est déplacée.
    

    
    Une autre cause fréquente d'erreurs "File Not Found" est l'erreur de
    frappe accidentelle dans les URLs, soit directement dans le navigateur,
    soit dans les liens HTML. httpd propose le module
    mod_speling (sic) pour tenter de résoudre ce problème.
    Lorsque ce module est activé, il intercepte les erreurs
    "File Not Found" et recherche une ressource possédant un nom de fichier
    similaire. Si un tel fichier est trouvé, mod_speling va envoyer une
    redirection HTTP au client pour lui communiquer l'URL correcte.
    Si plusieurs fichiers proches sont trouvés, une liste des alternatives
    possibles sera présentée au client.
    

    
    mod_speling possède une fonctionnalité particulièrement utile :
    il compare les noms de fichiers sans tenir compte de la casse.
    Ceci peut aider les systèmes où les utilisateurs ne connaissent pas la
    sensibilité des URLs à la casse et bien sûr les systèmes de fichiers unix.
    Mais l'utilisation de mod_speling pour toute autre chose que la correction
    occasionnelle d'URLs peut augmenter la charge du serveur, car chaque
    requête "incorrecte" entraîne une redirection d'URL et une nouvelle requête
    de la part du client.
    

    
    mod_dir fournit la directive FallbackResource qui permet d'associer
    des URIs virtuels à une ressource réelle qui peut ainsi les servir.
    Cette directive remplace avantageusement
    mod_rewrite lors de l'implémentation d'un
    "contrôleur frontal".
    

    
    Si toutes les tentatives pour localiser le contenu
    échouent, httpd
    retourne une page d'erreur avec le code de statut HTTP 404
    (file not found). L'apparence de cette page est contrôlée à l'aide de la
    directive ErrorDocument
    et peut être personnalisée de manière très flexible comme discuté dans le
    document
    Réponses personnalisées aux erreurs.

    Apache HTTP サーバはモジュール化されたプログラムで、
    管理者がモジュールを選択することでサーバに組み込む機能を選ぶことができます。
    モジュールはサーバがビルドされるときに httpd バイナリに
    静的に組み込むことができます。もしくは、httpd バイナリとは
    別に存在する動的共有オブジェクト (訳注: Dynamic Shared Object)
    (DSO) としてコンパイルすることも
    できます。DSO モジュールはサーバがビルドされるときにコンパイルしたり、
    Apache 拡張ツール (apxs) を
    使って後でコンパイルして追加したりできます。
    

    
    この文書は DSO モジュールの使い方と、仕組みについて
    説明します。

    実装
    


    関連モジュール関連ディレクティブ
    

    
    個々の Apache モジュールをロードするための DSO サポートは
    mod_so.c というモジュールの機能に基づいています。
    このモジュール は Apache のコアに静的に組み込まれている必要があります。
    それは core.c 以外では DSO にできない唯一の
    モジュールです。事実上、他のすべての Apache のモジュールは、
    インストールの文書で説明されているように、
    configure の
    --enable-module=shared オプションでそれぞれを
    DSO ビルドにすることにより、DSO モジュールにすることができます。
    mod_foo.so のような DSO にモジュールがコンパイルされれば、
    httpd.conf ファイル中で mod_so の
    LoadModule
    ディレクティブを使うことでサーバの起動や再起動時にこのモジュールを
    ロードするようにできます。
    

    
    Apache モジュール用の (特にサードパーティモジュールの) DSO ファイルの
    作成を簡単にするために、apxs
    (APache eXtenSion) という新しいサポートプログラムがあります。
    Apache のソースツリーの外で DSO モジュールをビルドするために
    使うことができます。発想は単純です: Apache のインストール時の
    configure、make install のときに Apache の
    C ヘッダをインストールし、DSO ビルド用のプラットフォーム依存の
    コンパイラとリンカのフラグを apxs プログラムに追加します。
    これにより、ユーザが Apache の配布ソースツリーなしで、さらに
    DSO サポートのためのプラットフォーム依存のコンパイラやリンカの
    フラグをいじることなく Apache のモジュールのソースをコンパイル
    できるようになります。
    

    top
    

    

    使用法の概要
    

    
    Apache 2.x の DSO 機能の概略を知ることができるための、
    短く簡潔な概要です:
    

    
      
      
    1. 
        配布されている Apache モジュール、仮に mod_foo.c
        として、それを DSO mod_foo.so にビルド、インストール: 


      
$ ./configure --prefix=/path/to/install --enable-foo=shared
      
$ make install

      
      
      2. 

      
    2. 
        サードパーティ Apache モジュール、仮に mod_foo.c
        として、それを DSO mod_foo.so にビルド、インストール:


      
$ ./configure --add-module=module_type:/path/to/3rdparty/mod_foo.c \
      

  --enable-foo=shared
      
      
$ make install

      
      
      3. 

      
    3. 
        共有モジュールの 後々のインストール のために
        Apache を設定:


      
$ ./configure --enable-so
      
$ make install

      
      
      4. 

      
    4. 
        サードパーティ Apache モジュール、仮に mod_foo.c
        として、それを apxs を使って
        Apache ソースツリーの外で DSO にビルド、インストール:


      
$ cd /path/to/3rdparty
      
$ apxs -c mod_foo.c
      
$ apxs -i -a -n foo mod_foo.la

      
      
      5. 
    
    

    
    どの場合においても、共有モジュールをコンパイルした後で、
    httpd.conf で 
    LoadModule
    ディレクティブを使って Apache がモジュールを使用するように
    しなければなりません。
    

    top
    

    

    背景
    

    
    最近の Unix 系の OS には 動的共有オブジェクト (DSO)
    の動的リンク/ロードという気のきいた機構が
    存在します。これは、実行時にプログラムのアドレス空間に
    ロードできるような特別な形式でプログラムをビルドすることを
    可能にします。
    

    
    このロードは二つの方法で行なうことができます: 実行プログラムが
    起動されたときに ld.so というシステムプログラム
    により自動的に行なわれる方法と、実行プログラム中から、システムコール
    dlopen()/dlsym() による Unix ローダへの
    プログラムシステムのインタフェースを使って手動で行なう方法とが
    あります。
    

    
    最初の方法では DSO は普通は共有ライブラリや DSO
    ライブラリ と呼ばれていて、DSO の名前は
    libfoo.so や libfoo.so.1.2 のようになっています。
    これらはシステムディレクトリ (通常 /usr/lib) に存在し、
    実行プログラムへのリンクはビルド時に -lfoo をリンカに
    指定することで確立されます。これによりライブラリへの参照が実行プログラムの
    ファイルに書き込まれて、起動時に Unix のローダが /usr/lib や、
    リンカの -R のようなオプションによりハードコードされたパス、
    環境変数 LD_LIBRARY_PATH により設定されたパス、の中から
    libfoo.so の場所を見つけることができます。それから、
    実行プログラム中の (まだ未解決の) シンボルを DSO にあるシンボルで
    解決します。
    

    
    普通は実行プログラム中のシンボルは DSO からは参照されません
    (DSO は一般的なコードによる再利用可能なライブラリですので)。
    ですから、さらなるシンボルの解決は必要ありません。
    シンボルは Unix ローダにより完全な解決が行なわれますので、実行ファイル自身は
    何もする必要がありません。(実際のところ、静的でない方法でリンクされている
    すべての実行プログラムに組み込まれている開始用のコードの一部に
    ld.so を起動するコードが含まれています)。よく使われる
    ライブラリの動的ロードの利点は明らかです。ライブラリのコードは
    システムライブラリに libc.so のようにして一度保存するだけでよく、
    プログラムのために必要なディスクの領域を節約することができます。
    

    
    二つめの方法では DSO は普通は共有オブジェクトや
    DSO ファイルと呼ばれていて、任意の拡張子を付けることができます
    (ただし、標準的な名前は foo.so です)。
    これらのファイルは通常はプログラム専用のディレクトリに置かれ、
    これらを使う実行プログラムへのリンクは自動的にはされません。
    ですので、実行プログラムは dlopen() を使って
    実行時に手動で DSO をプログラムのアドレス空間にロードする必要があります。
    この時点では実行プログラムに対して DSO のシンボルの解決は行なわれません。
    しかし、その代わりに Unix のローダが DSO の (まだ未解決の) シンボルを
    実行プログラムによりエクスポートされたシンボルと既にロードされた
    DSO ライブラリによりエクスポートされたシンボル (特に、どこにでもある
    libc.so のすべてのシンボル) で自動的に解決します。
    こうすることで、DSO は最初から静的にリンクされていたかのように、
    実行プログラムのシンボルを知ることができます。
    

    
    最後に、DSO の API を利点を生かすために、プログラムは
    後でディスパッチテーブルなどでシンボルを使うことができるように、
    dlsym() を使っていくつかのシンボルを解決します。
    すなわち: 実行プログラムは必要なすべてのシンボルを手動で解決しなければ
    なりません。この機構の利点はプログラムのオプショナルな部分は
    必要になるまでロードする必要がない (だからメモリも消費しない)
    ことです。必要ならば、基本プログラムの機能を拡張するために
    これらの部分を動的にロードすることができます。
    

    
    この DSO 機構は簡単なように見えますが、少なくとも一つ難しい点が
    あります: プログラムを拡張するために DSO を使っているときに、
    DSO が実行プログラムからシンボルを解決する点です (二番目の方法)。
    これはなぜでしょうか。それは、DSO のシンボルを実行プログラムの
    シンボルから「逆解決」するというのはライブラリの設計
    (ライブラリはそれを使用するプログラムのことは何も
    知らない) に反していて、この機能はすべてのプラットフォームに
    あるわけではなく、標準化もされていないからです。
    実際には実行プログラムのグローバルなシンボルは再エクスポートされることは
    あまりなく、DSO から使うことができません。リンカにグローバルシンボルすべてを
    エクスポートするようにさせる方法を見つけることが、実行時にプログラムを
    拡張するために DSO を使うときの一番の問題です。
    

    
    共有ライブラリのアプローチが普通の方法です。DSO 機構はそのために
    設計されたものですから。したがって、その方法はオペレーティングシステムが
    提供するほとんどすべての種類のライブラリで使われています。
    一方、プログラムの拡張のために共有オブジェクトを使用する、という方は
    あまり使われていません。
    

    
    1998 年の時点で、実行時に実際に機能拡張のために DSO 機構を使っている
    ソフトウェアパッケージは少しだけでした: Perl 5 (XS 機構と DnaLoader モジュール
    によるもの)、Netscape サーバなどです。Apache はすでに
    モジュールの概念を使って機能拡張をしていて、内部的にディスパッチリストに
    基づいた外部モジュールの Apache コア機能へのリンクを行なっていましたので、
    バージョン 1.3 から、Apache も DSO 機構を使う仲間になりました。
    Apache は実行時に DSO を使ってモジュールをロードするようにすでに
    運命付けられていたのです。

    利点と欠点
    

    
    上記の DSO に基づいた機能は以下の利点があります:
    

    
      
      
    • 実際のサーバプロセスを組み立てるために、
      ビルド時に configure のオプションを使う代わりに
      実行時に httpd.conf の設定用コマンド
      LoadModule
      を使うことができますので、サーバパッケージの柔軟性が高まりました。
      たとえば、一つの Apache のインストールから
      違う構成のサーバ (標準版と SSL 版、最小構成と拡張版 [mod_perl, PHP3]
      など) を実行することができます。

    • インストールの後であっても、サーバのパッケージをサードパーティ
      モジュールで簡単に拡張できるようになりました。これは、Apache コア
      パッケージと、PHP3, mod_perl, mod_fastcgi など の追加の
      パッケージを作成できるので、少なくともベンダのパッケージ管理者にとって
      大きな利点があります。
      • 

      
    • Apache モジュールの開発が簡単になります。
      これは DSO と apxs の組み合わせにより、Apache ソースツリーの
      外で作業でき、開発中のモジュールの新しいバージョンを
      実行中の Apache サーバに組み込むために apxs -i と
      apachectl restart を行なうだけで良くなるからです。
      • 
    
    

    
    DSO には以下の欠点があります:
    

    
      
      
    • すべてのオペレーティングシステムがプログラムのアドレス空間に
      コードを動的ロードすることをサポートしているわではないので、
      プラットフォームによっては DSO 機構は使えません。
      • 

      
    • Unix のローダがシンボルの解決をする必要ができたので、
      そのオーバヘッドによりサーバの起動時間が約 20% 遅くなっています。
      • 

      
    • 位置非依存コード (PIC) (訳注 position independent code) は
      相対アドレスのために複雑なアセンブラのトリックが必要なことがあり、
      それは必ずしも絶対アドレスと同じくらいの速度がでるわけではありませんので、
      プラットフォームによってはサーバの実行速度が約 5% 遅くなります。
      • 

      
    • DSO モジュールはすべてのプラットフォームで他の DSO に基づいた
      ライブラリに対してリンクできる (ld -lfoo)
      というわけではありませんので (たとえば、a.out のプラットフォームでは
      この機能はありませんが、ELF のプラットフォームにはあります)、
      すべての種類のモジュールに DSO 機構を使えるわけではありません。
      言い換えると、DSO ファイルとしてコンパイルされたモジュールの
      使えるシンボルは、
      Apache のコアのシンボル、C ライブラリ (libc) と
      Apache コアが使っている他のすべての静的なライブラリと動的ライブラリの
      シンボル、PIC による静的なライブラリ (libfoo.a) の
      シンボルのみに制限されます。その他のコードを使う方法は、
      Apache コア自身がすでにそのコードへの参照があるようにするか、
      dlopen () を使ってコードを自分自身でロードするかの
     どちらかしかありません。

    Definiciones
    
		
    
		
    Algoritmo
    
		
    Un proceso definido sin ambigüedades o un conjunto de reglas 
		para solucionar un problema en un número finito de pasos.
		Los algoritmos para encriptar se llaman
		normalmente algoritmos de cifrado.
		
    


		
    Algoritmo de cifrado, (Cipher). 
    
		
    Es un algoritmo o sistema de encriptado de información. 
		Ejemplos de estos algoritmos son DES, IDEA, RC4, etc.
    
		Consulte: Encriptado SSL/TLS
    

		
    Autenticación.
    
		
    La identificación positiva de una entidad de red tal como un
		servidor, un cliente, o un usuario.
     
		Consulte: Autentificación, Autorización, 
		y Control de Acceso
    


		
    Autoridad Certificadora. (CA)
     
    Es una entidad externa de confianza cuyo fin
		es firmar certificados para las entidades de red que ha autentificado
		usando medios seguros. Otras entidades de red pueden verificar la
		firma para comprobar que una Autoridad Certificadora ha autentificado
		al poseedor del certificado.
     Consulte: Encriptado
		SSL/TLS
    


		
    Cabecera.
     
    Es la parte de la
		petición y la respuesta HTTP que se
		envía antes del contenido propiamente dicho, y que contiene
		meta-información describiendo el contenido.
    

		
    Certificado.
    
		
    Una información que se almacena para autenticar entidades
		de red tales como un servidor o un cliente. Un certificado
		contiene piezas de información X.509 sobre su poseedor
		(llamado sujeto) y sobre la Autoridad Certificadora
		(llamada el emisor) que lo firma, más la clave pública del propietario y la firma de
		la AC(Autoridad Certificadora). Las entidades de red verifican las firmas usando
		certificados de las AC.
    
		Consulte: Encriptado SSL/TLS
		
    



		
    Clave Pública.
     
		
    La clave disponible
		públicamente en un sistema
		criptográfico de Clave Pública, usado para encriptar
		mensajes destinados a su propietario y para desencriptar firmas hechas
		por su propietario.
     Consulte: Encriptado
		SSL/TLS
    



		
    Clave Privada.
    
		
    La clave secreta
		de un Sistema criptográfico de
		Clave Pública, usada para desencriptar los mensajes entrantes
		y firmar los salientes.
     Consulte: Encriptado
		SSL/TLS
    


		
    CONNECT
     
    Un método de HTTP para hacer proxy a canales de
		datos sin usar HTTP. Puede usarse para encapsular otros protocolos,
		tales como el protocolo SSL.
    



		
    Contexto
     
    Un área en los
		ficheros de configuración
		donde están permitidos ciertos tipos de directivas.
    
		Consulte: Términos 
		usados para describir las directivas de Apache
    


		
    Control de Acceso.
     
		
    La
		restricción en el acceso al entorno de una red. En el contexto de
		Apache significa normalmente la restricción en el acceso a
		ciertas URLs.
     
		Consulte: Autentificación, Autorización, y
		Control de Acceso
    


		
    Criptografía
		Simétrica
     
    El estudio y aplicación de
		Algoritmos de Cifrado que usan una sola clave secreta tanto
		para cifrar como para descifrar.
     Consulte: Encriptado SSL/TLS
    


		
    Directiva
    
		
    Un comando de
		configuración que controla uno o más aspectos del
		comportamiento de Apache.  Las directivas se ponen en el Fichero de Configuración
    
		Consulte: Índice de
		Directivas
    

		
    Directivas de
		configuración.
     
    Consulte: Directivas
    

		
    Entorno Portable de tiempo de ejecución de Apache,  (APR, Apache Portable Runtime)
    
		
    Es un conjunto de librerías que proveen las interfaces básicas 
		entre el servidor y el sistema operativo. El desarrollo de APR es 
		paralelo al del Servidor HTTP Apache, como un proyecto independiente. 
		Puedes visitar el proyecto en:
    
		Apache Portable Runtime
		Project
		
    

		
    Export-Crippled
    
		
    Disminución de la fortaleza criptográfica (y seguridad)
		para cumplir con las Regulaciones sobre Exportación de la
		Administración de los Estados Unidos (EAR). El software
		criptográfico Export-crippled está limitado a una clave de
		pequeño tamaño, de tal manera que el texto cifrado
		que se consigue con él, puede descifrarse por medio de fuerza bruta.
     Consulte: Encriptado SSL/TLS
    


		
    Expresiones Regulares 
		(Regex)
     
    Una forma de describir un patrón en un 
		texto - por ejemplo, "todas las palabras que empiezan con la letra "A"
		o "todos los números de teléfono que contienen 10
		dígitos" o incluso "Todas las frases entre comas, y que no
		contengan ninguna letra Q". Las Expresiones Regulares son útiles en
		Apache porque permiten aplicar ciertos atributos a colecciones de
		ficheros o recursos de una forma flexible - por ejemplo, todos los
		archivos .gif y .jpg que estén en el directorio "imágenes"
		podrían ser escritos como "/images/.*(jpg|gif)$".
		En los lugares donde expresiones regulares se utilizan para reemplazar
		cadenas, las variables especiales $ 1 ... $ 9 contienen 
		referencias inversa las partes agrupadas (entre paréntesis) 
		de la expresión coincidente. La variable especial $ 0 contiene 
		una referencia inversa a todo el ejemplar de la expresión.
		Para escribir un símbolo de dolar literal en una sustitución de
		una cadena, se puede escapar usando "\". Históricamente, la variable &
		se podía usar como un alias a $0 en algunos sitios. 
		Esto ya no esta soportado desde la versión 2.3.6.
		Apache usa Expresiones Regulares compatibles con Perl gracias a la
		librería PCRE.
		Puedes encontrar más documentación sobre las expresiones regulares 
		de PCRE y su sintaxis en esa página o en la
		Wikipedia.
    



		
    Fichero de Configuración.
    
		
    Un fichero de texto que contiene Directivas que controlan la configuración
		de Apache.
     Consulte: Ficheros de
		Configuración
    


		
    .htaccess
     
		
    Un fichero de configuración que se
		pone dentro de la estructura de directorios del sitio web y aplica directivas de configuración al directorio
		en el que está y a sus subdirectorios. A pesar de su nombre, este
		fichero puede contener cualquier tipo de directivas, no solo
		directivas de control de acceso.
     Consulte: Ficheros de Configuración para más información.
    

		
    httpd.conf
    
		
    Es el fichero de configuración principal
		de Apache. Su ubicación por defecto es
		/usr/local/apache2/conf/httpd.conf, pero puede moverse
		usando opciones de configuración al compilar o al iniciar
		Apache.
     Consulte: Ficheros de
		Configuración
    

		
    Filtro
    
		
    Un proceso que se aplica a la
		información que es enviada o recibida por el servidor. Los
		ficheros de entrada procesan la información enviada por un
		cliente al servidor, mientras que los filtros de salida procesan la
		información en el servidor antes de enviársela al
		cliente. Por ejemplo, el filtro de salida INCLUDES
		procesa documentos para Server Side Includes.
    
		Consulte: Filtros
    



		
    Firma Digital
    
		
    Un bloque de
		texto encriptado que verifica la validez de un certificado o de otro
		fichero. Una Autoridad
		Certificadora crea una firma generando un hash a partir de la
		Clave Pública que lleva incorporada en un
		Certificado, después encriptando el hash con su propia
		Clave Privada. Solo las claves públicas de las CAs
		pueden desencriptar la firma, verificando que la CA ha autentificado a
		la entidad de red propietaria del Certificado.
    
		Consulte: Encriptado SSL/TLS
    

		
    Handler
     
		
    Es una representación
		interna de Apache de una acción a ser ejecutada cuando se llama a
		un fichero. Generalmente, los ficheros tienen un handler (manejador)
		implícito, basado en el tipo de fichero. Normalmente, todos los
		ficheros son simplemente servidos por el servidor, pero sobre algunos
		tipos de ficheros se ejecutan acciones complementarias.  Por ejemplo,
		el handler cgi-script designa los ficheros a ser
		procesados como CGIs.
     Consulte: Uso de Handlers en Apache
    

		
    Herramienta de extensión de
		Apache. (apxs)
    
		
    Es un script escrito en Perl que ayuda a compilar el código
		fuente de algunos módulos para 
		convertirlos en Objetos Dinámicos Compartidos (DSOs)
		y ayuda a instalarlos en el Servidor Web de Apache.
     
		Consulte: Manual de: apxs
    



		
    Hash
    
		
    Algoritmo matemático de un solo sentido e irreversible, que genera
		una cadena de una determinada longitud de otra cadena de 
		cualquier tamaño. Diferentes entradas darán diferentes hashes 
		(dependiendo de la función hash.) 
		
    





		
    Hosting Virtual
     
    Se trata de
		servir diferentes sitios web con una sola entidad de Apache.  El
		hosting virtual de IPs diferencia los sitios web basándose en sus
		direcciones IP, mientras que el hosting virtual basado en
		nombres usa solo el nombre del host y de esta manera puede alojar
		muchos sitios web con la misma dirección IP.
     Consulte: Documentación sobre Hosting Virtual en
		Apache
    


		
    Identificador de Recursos
		Uniforme (URI)
     
    Una cadena de caracteres
		compacta para identificar un recurso físico o abstracto.  Se
		define formalmente en la RFC 2396.  Los URIs que
		se usan en world-wide web se refieren normalmente como URLs.
    




		
    Indicador del Nombre del servidor
		 Server Name Indication (SNI) 
    
		
    Una función SSL que permite pasar el nombre de host del servidor deseado 
		en el mensaje inicial del protocolo de enlace SSL, para que el servidor web 
		pueda seleccionar la configuración correcta del host virtual para usar en el 
		procesamiento del protocolo de enlace SSL. Se añadió a SSL 
		con las extensiones TLS en el RFC 3546.  
    
		See: the SSL FAQ
		and RFC 3546
		
    




		
    Interfaz de Pasarela Común.  Common Gateway Interface (CGI)
    
		
    Una definición estándar para
		un interfaz entre un servidor web y un programa externo que permite
		hacer peticiones de servicio a los programas externos.  Este interfaz
		esta definido en el  RFC-3875.
    
		Consulte: Contenido Dinámico con CGI
		
    

		
    Localizador de Recursos
		Uniforme (URL)
    
		
    El nombre de un recurso
		en Internet.  Es la manera informal de decir lo que formalmente se
		llama un Identificador de
		Recursos Uniforme.  Las URLs están compuestas normalmente por
		un esquema, tal como http o https, un nombre
		de host, y una ruta.  Una URL para esta página es
		http://httpd.apache.org/docs/2.4/glossary.html.
    


		
    Módulo
    
		
    Una parte independiente
		de un programa. La mayor parte de la funcionalidad de Apache
		está contenida en módulos que pueden incluirse o excluirse.
		Los módulos que se compilan con el binario httpdde Apache se
		llaman módulos estáticos, mientras que los que se
		almacenan de forma separada y pueden ser cargados de forma opcional,
		se llaman módulos dinámicos o DSOs.
		Los módulos que están incluidos por defecto de llaman
		módulos base.  Hay muchos módulos disponibles para
		Apache que no se distribuyen con la tarball del
		Servidor HTTP Apache.  Estos módulos son llamados
		módulos de terceros.
     Consulte: Índice de Módulos
    


		
    Método
     
		
    En el contexto de HTTP, es una acción a ejecutar sobre un recurso,
		especificado en la líneas de petición por el cliente.
		Algunos de los métodos disponibles en HTTP son GET,
		POST, y PUT.
    

		
    Mensaje Resumen (Message Digest)
     
		
    Un hash de un
		mensaje, el cual pude ser usado para verificar que el contenido del
		mensaje no ha sido alterado durante la transmisión.
    
		Consulte: Encriptado SSL/TLS
    

		
    MIME-type
     
		
    Una manera de describir
		el tipo de documento a ser transmitido.  Su nombre viene del hecho de
		que su formato se toma de las Extensiones del "Multipurpose Internet
		Mail".  Consiste en dos componentes, uno principal y otro secundario,
		separados por una barra.  Algunos ejemplos son text/html,
		image/gif, y application/octet-stream.  En
		HTTP, el tipo MIME se transmite en la cabecera
		del Tipo Contenido.
     Consulte: mod_mime
    

		
    Módulo del Número Mágico
		(MMN Module Magic
		Number)
     
     El módulo del número
		mágico es una constante definida en el código
		fuente de Apache que está asociado con la compatibilidad binaria
		de los módulos. Ese número cambia cuando cambian las
		estructuras internas de Apache, las llamadas a funciones y otras
		partes significativas de la interfaz de programación de manera
		que la compatibilidad binaria no puede garantizarse sin cambiarlo.  Si
		cambia el número mágico de módulo, todos los
		módulos de terceros tienen que ser al menos recompilados, y
		algunas veces, incluso hay que introducir ligeras modificaciones para
		que funcionen con la nueva versión de Apache 
    


		
    Nombre de dominio
		completamente qualificado (FQDN)
     
		
    El
		nombre único de una entidad de red, que consiste en un nombre de
		host y un nombre de dominio que puede traducirse a una dirección
		IP. Por ejemplo, www es un nombre de host,
		example.com es un nombre de dominio, y
		www.example.com es un nombre de dominio completamente
		qualificado.
    

		
    Objetos Dinámicos
		Compartidos (DSO, dinamic shared objects)
    
		
    Los Módulos compilados de forma separada al
		binario httpd de Apache se pueden cargar según se necesiten.
     Consulte: Soporte de Objetos Dinámicos
		Compartidos
    


		
    OpenSSL
    
		
    El toolkit Open Source para SSL/TLS
    
		Ver: http://www.openssl.org/
    


		
    Pass Phrase o frase de contraseña
     
		
    La palabra o frase
		que protege los archivos de clave privada.  Evita que usuarios no
		autorizados los encripten. Normalmente es solo la clave de
		encriptado/desencriptado usada por los Algoritmos de
		Cifrado.
     Consulte: Encriptado
		SSL/TLS
    

		
    Petición de firma de
		Certificado. (CSR)
     
		
    Es la petición a
		una Autoridad Certificadora para
		que firme un certificado aún sin
		firmar. La Autoridad Certificadora firma el Certificado con
		la Clave Privada de su 
		certificado. Una vez que el CSR está firmado, se 
		convierte en un auténtico certificado.
     
		Consulte: Encriptado SSL/TLS
    



		
    Protocolo de Transferencia de
		Hipertexto (HTTP)
     
		
    Es el protocolo de
		transmisión estádar usado en la World Wide Web.  Apache
		implementa la versión 1.1 de este protocolo, al que se hace
		referencia como HTTP/1.1 y definido por el RFC 2616.
    

		
    HTTPS
    
		
    Protocolo de transferencia de
		Hipertexto (Seguro), es el mecanismo de comunicación encriptado

    Proxy
     
    Un servidor intermedio que se
		pone entre el cliente y el servidor de origen.  Acepta las
		peticiones de los clientes, las transmite al servidor de origen, y
		después devuelve la respuesta del servidor de origen al
		cliente. Si varios clientes piden el mismo contenido, el proxy sirve
		el contenido desde su caché, en lugar de pedirlo cada vez que lo
		necesita al servidor de origen, reduciendo con esto el tiempo de
		respuesta.
     Consulte: mod_proxy
    


		
    Proxy Inverso
    
		
    Es un servidor
		proxy que se presenta al cliente como si fuera un
		servidor de origen.  Es útil para esconder el
		auténtico servidor de origen a los clientes por cuestiones de
		seguridad, o para equilibrar la carga.
    


		
    SSL, Capa de Conexión Segura  Secure Sockets Layer(SSL)
     
    Es un protocolo creado por Netscape
		Communications Corporation para la autenticación en
		comunicaciones en general y encriptado sobre redes TCP/IP. Su
		aplicación más popular es en HTTPS, ejemplo.: el Protocolo de
		Transferencia de Hipertexto (HTTP) sobre SSL.

    Server Side Includes (SSI)
     
    Una técnica para incluir directivas de
		proceso en archivos HTML.
     Consulte: Introducción a Server Side
		Includes
    



		
    Sesión
     
    Información del

    Sistema Criptográfico de Clave
		Pública
     
    El estudio y aplicación de sistemas de
		encriptado asimétricos, que usa una clave para encriptar y otra
		para desencriptar. Una clave de cada uno de estos tipos constituye un
		par de claves. También se llama Criptografía Asimétrica.
    
		Consulte:  Encriptado SSL/TLS
    


		
    Subconsulta
    
		
    Apache proporciona una API de subconsultasd a los módulos,
		que permiten a otros sistemas de ficheros o paths de URL ser parcial o totalmente evaluados
		por el servidor. Un ejemplo de los que usan esta API sería
		DirectoryIndex,
		mod_autoindex, y mod_include.
		
    

		
    Tarball
     
    Un grupo de ficheros
		puestos en un solo paquete usando la utilidad tar.  Las
		distribuciones Apache se almacenan en ficheros comprimidos con tar o
		con pkzip.

    Transport 
			Layer Security (TLS)
     
    Es el sucesor del protocolo SSL, creado
		por el "Internet Engineering Task Force" (IETF) para la
		autentificación en comunicaciones en general y encriptado sobre
		redes TCP/IP. La versión 1 de TLS es casi idéntica a la
		versión 3 de SSL.
     Consulte: Encriptado
		SSL/TLS
    


		
    Variable de Entorno (env-variable)
     
		
    Variables que
		gestionan el shell del sistema operativo y que se usan para guardar
		información y para la comunicación entre programas.  Apache
		también contiene variables internas que son referidas como
		variables de entorno, pero que son almacenadas en las estructuras
		internas de Apache, en lugar de en el entorno del shell.
    
		Consulte: Variables de entorno de Apache
    


		
    X.509
     
    Un esquema de certificado de
		autentificación recomendado por la International
		Telecommunication Union (ITU-T) que se usa en la autentificación
		SSL/TLS.

Les expressions dans le serveur HTTP Apache - Serveur HTTP Apache Version 2.4

    Les expressions dans le serveur HTTP Apache
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    
    Historiquement, il existe de nombreuses variantes dans la syntaxe
    des expressions permettant d'exprimer une condition dans les
    différents modules du serveur HTTP Apache. À ce titre, des travaux sont
    en cours pour n'utiliser qu'une seule variante nommée
    ap_expr, pour toutes les directives de configuration. Ce
    document décrit l'interpréteur d'expressions ap_expr.
    
    
    
    Le type d'expression ap_expr est appelé à remplacer la
    plupart des autres types d'expressions dans HTTPD. Par exemple, la
    directive obsolète SSLRequire peut être remplacée par la
    directive Require
    expr.

    Syntaxe en Forme de Backus-Naur
    
    
      
    La Forme de Backus-Naur
      (souvent abrégée en BNF, de l'anglais Backus-Naur Form) est une notation permettant de décrire
      les règles syntaxiques des langages de programmation. En
      général, les expressions représentent des valeurs booléennes. Dans
      ce cas, le point de départ de la BNF est expr.
      Cependant, certaines directives comme LogMessage utilisent comme
      paramètres des expressions qui représentent des chaînes de
      caractères. Dans ce cas, le point de départ de la BNF est
      string.
      
    

    

    expr        ::= "true" | "false"
              | "!" expr
              | expr "&&" expr
              | expr "||" expr
              | "(" expr ")"
              | comp

comp        ::= stringcomp
              | integercomp
              | unaryop word
              | word binaryop word
              | word "in" "{" wordlist "}"
              | word "in" listfunction
              | word "=~" regex
              | word "!~" regex


stringcomp  ::= word "==" word
              | word "!=" word
              | word "<"  word
              | word "<=" word
              | word ">"  word
              | word ">=" word

integercomp ::= word "-eq" word | word "eq" word
              | word "-ne" word | word "ne" word
              | word "-lt" word | word "lt" word
              | word "-le" word | word "le" word
              | word "-gt" word | word "gt" word
              | word "-ge" word | word "ge" word

wordlist    ::= word
              | wordlist "," word

word        ::= word "." word
              | digit
              | "'" string "'"
              | """ string """
              | variable
	      | rebackref
              | function

string      ::= stringpart
              | string stringpart

stringpart  ::= cstring
              | variable
	      | rebackref

cstring     ::= ...
digit       ::= [0-9]+

variable    ::= "%{" varname "}"
              | "%{" funcname ":" funcargs "}"

rebackref   ::= "$" [0-9]

function     ::= funcname "(" word ")"

listfunction ::= listfuncname "(" word ")"

    Variables
    
    

    
    L'interpréteur d'expressions fournit plusieurs variables de la
    forme %{HTTP_HOST}. Notez que la valeur d'une variable
    peut dépendre de la phase du traitement de la requête au cours de
    laquelle elle est évaluée. Par exemple, une expression utilisée dans
    une directive <If > sera évaluée avant
    la phase d'authentification. Par conséquent, la variable
    %{REMOTE_USER} ne sera pas encore définie à ce stade.
    

    
    Les variables suivantes contiennent la valeur de l'en-tête de
    requête HTTP correspondant. La fonction
    req permet d'extraire les valeurs des autres
    en-têtes. L'utilisation de ces variables peut provoquer
    l'ajout du nom d'en-tête correspondant à l'en-tête Vary de la
    réponse HTTP, sauf spécification contraire pour la directive
    qui accepte l'expression comme paramètre. La function req_novary permet de
    modifier ce comportement.

    Fonctions
    
    

    
    Normalement, les fonctions dont la valeur est une chaîne acceptent une chaîne
    comme argument et renvoient une chaîne. Les noms de fonctions sont
    insensibles à la casse. Les modules peuvent fournir des fonctions
    supplémentaires.

        Lit le contenu d'un fichier(fins de lignes incluses, si
	elles existent)limité

	fichier n'existe pas ou n'est pas un fichier régulier)limité
    

    filesize
        Renvoie la taille d'un fichier (ou 0 si le fichier n'existe
	pas ou ne correspond pas à un fichier régulier)limité
    

    

    
    Les fonctions marquées comme "limité" dans la dernière colonne ne sont
    pas disponibles avec certains modules comme
    mod_include.
    

    
    Les fonctions marquées comme "ordonnancement" dans la dernière colonne
    nécessitent une attention particulière pour l'ordonnancement des différents
    composants du serveur, spécialement lorsque la fonction est utilisée au sein
    d'une directive <If> qui est
    évaluée relativement tôt.
    
    
    
    
    Ordonnancement des variables d'environnement
    
    Lorsque des variables d'environnement sont évaluées au sein d'une directive
    <If>, il est important de tenir
    compte du moment où cette évaluation intervient dans le traitement de la
    requête. Par exemple, toute directive définie en dehors d'un contexte de
    serveur virtuel (directory, location, htaccess) aura peu de chance d'être
    déjà exécutée. Ainsi la directive SetEnvIf est une directive qui s'exécute
    avant cette évaluation.
    
    
    
    
    Lorsque reqenv est utilisé en dehors de la directive
    <If>, l'évaluation survient en
    général plus tard, mais le moment exact dépend de la directive dans laquelle
    l'expression a été utilisée.
    
    

    
    Lorsque les fonctions req ou http sont
    utilisées, le nom d'en-tête sera automatiquement ajouté à l'en-tête
    Vary de la réponse HTTP, sauf spécification contraire pour la
    directive qui accepte l'expression comme paramètre. La
    fonction req_novary permet d'empêcher l'ajout de noms
    d'en-têtes à l'en-tête Vary.
    

    
    En plus des fonctions dont la valeur est une chaîne, il existe
    aussi des fonctions dont la valeur est une liste, qui acceptent une
    chaîne comme argument, et renvoient une liste de mots, autrement dit
    une liste de chaînes. La liste de mot peut être utilisée avec
    l'opérateur spécial -in. Les noms de fonctions sont
    insensibles à la casse. Les modules peuvent fournir des fonctions
    supplémentaires.
    

    
    Il n'existe pas de fonctions internes dont la valeur est une
    liste. Le module mod_ssl fournit la fonction
    PeerExtList. Voir la description de la directive
    SSLRequire pour plus de
    détails (notez que la fonction PeerExtList peut aussi
    être utilisée en dehors de la directive SSLRequire).

Getting Started - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Getting Started
    

    

    Available Languages:  en  |
 fr  |
 ru 
    

    


    If you're completely new to the Apache HTTP Server, or even to running
a website at all, you might not know where to start, or what questions to
ask. This document walks you through the basics.
    

    


    top
    

    

    Clients, Servers, and URLs
    



    
Addresses on the Web are expressed with URLs - Uniform Resource Locators
- which specify a protocol (e.g. http), a servername (e.g.
www.apache.org), a URL-path (e.g.
/docs/current/getting-started.html), and possibly a query
string (e.g. ?arg=value) used to pass additional
arguments to the server.

    


    A client (e.g., a web browser) connects to a server (e.g., your Apache HTTP Server),
with the specified protocol, and makes a request for a resource using the
URL-path.
    


    The URL-path may represent any number of things on the server. It may
be a file (like getting-started.html) a handler (like server-status) or some kind of program
file (like index.php). We'll discuss this more below in
the Web Site Content section.
    


    
The server will send a response consisting of a status
code and, optionally, a response body.
The status code indicates whether the request was successful, and, if not, what
kind of error condition there was. This tells the client what it should
do with the response. You can read about the possible response codes in
HTTP Server
wiki.
    


    Details of the transaction, and any error conditions, are written to
log files. This is discussed in greater detail below in the Logs Files and Troubleshooting section.
    


    top
    

    

    Hostnames and DNS
    



    In order to connect to a server, the client will first have to resolve
the servername to an IP address - the location on the Internet where the
server resides. Thus, in order for your web server to be reachable, it
is necessary that the servername be in DNS.
    


    If you don't know how to do this, you'll need to contact your network
administrator, or Internet service provider, to perform this step for
you.
    


    More than one hostname may point to the same IP address, and more
than one IP address can be attached to the same physical server. Thus, you
can run more than one web site on the same physical server, using a
feature called virtual hosts.
    


    If you are testing a server that is not Internet-accessible, you
can put host names in your hosts file in order to do local resolution.
For example, you might want to put a record in your hosts file to map a
request for www.example.com to your local system, for
testing purposes. This entry would look like:
    


    
127.0.0.1 www.example.com

    


    A hosts file will probably be located at /etc/hosts or
C:\Windows\system32\drivers\etc\hosts.
    


    You can read more about the hosts file at Wikipedia.org/wiki/Hosts_(file), and
more about DNS at Wikipedia.org/wiki/Domain_Name_System.
    

    top
    

    

    Configuration Files and Directives
    



    The Apache HTTP Server is configured via simple text files.
These files may be located any of a variety of places, depending on how
exactly you installed the server. Common locations for these files may
be found in
the httpd wiki. If you installed httpd from source, the default
location of the configuration files is
/usr/local/apache2/conf. The default configuration file is
usually called httpd.conf. This, too, can vary in
third-party distributions of the server.
    


    The configuration is frequently broken into multiple smaller files,
for ease of management. These files are loaded via the Include directive. The names or locations of
these sub-files are not magical, and may vary greatly from one
installation to another. Arrange and subdivide these files as
makes the most sense to you. If the file arrangement
you have by default doesn't make sense to you, feel free to rearrange it.
    


    The server is configured by placing configuration directives in these
configuration files. A directive is a keyword followed by one or more
arguments that set its value.
    


    The question of "Where should I put that
directive?" is generally answered by considering where you want a
directive to be effective. If it is a global setting, it should appear
in the configuration file, outside of any <Directory>, <Location>, <VirtualHost>, or other section. If it is to
apply only to a particular directory, then it should go inside a
<Directory> section referring to
that directory, and so on. See the Configuration
Sections document for further discussion of these sections.
    


    In addition to the main configuration files, certain directives may go in
.htaccess files located in the content directories.
.htaccess files are primarily for people who do not have
access to the main server configuration file(s). You can read more about
.htaccess files in the .htaccess howto.
    


    top
    

    

    Web Site Content
    



    Web site content can take many different forms, but may be broadly
divided into static and dynamic content.
    


    Static content is things like HTML files, image files, CSS files,
and other files that reside in the filesystem. The DocumentRoot directive specifies where in your
filesystem you should place these files. This directive is either set
globally, or per virtual host. Look in your configuration file(s) to
determine how this is set for your server.
    


    Typically, a document called index.html will be served
when a directory is requested without a file name being specified. For
example, if DocumentRoot is set to
/var/www/html and a request is made for
http://www.example.com/work/, the file
/var/www/html/work/index.html will be served to the
client.
    


    Dynamic content is anything that is generated at request
time, and may change from one request to another. There are numerous
ways that dynamic content may be generated. Various handlers are available to generate content. CGI programs may be written to generate
content for your site.
    


    Third-party modules like mod_php may be used to write code that does a
variety of things. Many third-party applications, written using a
variety of languages and tools, are available for download and
installation on your Apache HTTP Server. Support of these third-party
things is beyond the scope of this documentation, and you should find
their documentation or other support forums to answer your questions
about them.
    

    top
    

    

    Log Files and Troubleshooting
    


    As an Apache HTTP Server administrator, your most valuable assets are
the log files, and, in particular, the error log. Troubleshooting any
problem without the error log is like driving with your eyes closed.
    


    The location of the error log is defined by the ErrorLog directive, which may be set globally,
or per virtual host. Entries in the error log tell you what went wrong,
and when. They often also tell you how to fix it. Each error log message
contains an error code, which you can search for online for even more
detailed descriptions of how to address the problem. You can also
configure your error log to contain a log ID which you can then
correlate to an access log entry, so that you can determine what request
caused the error condition.
    


    You can read more about logging in the logs
documentation.

    What's next?
    



    Once you have the prerequisites under your belt, it's time to move
on.
    


    This document covers only the bare basics. We hope that this gets you
started, but there are many other things that you might need to
know.

    この文書では Unix に類似したシステムでの
    Apache HTTP Serverの停止と再起動について扱っています。
    Windows NT, 2000, XP ユーザはサービスとして
    httpd を実行するで、Windows 9x, MEユーザはコンソールアプリケーションとして
    httpd を実行するで、
    これらのプラットホームでの使用方法をご覧下さい。

    Apache HTTP Server を停止したり再起動したりするためには、実行されている
    httpd プロセスにシグナルを送る必要があります。
    シグナルを送るには二つの方法があります。
    一つ目はプロセスに直接シグナルを送る unix の kill
    コマンドを使用する方法です。
    システムを見ればたくさんの httpd が
    実行されているのに気が付くでしょうが、シグナルを送るのは
    親プロセスだけで、それ以外の個々のプロセスには
    シグナルを送らないで下さい。その親プロセスの pid は
    PidFile
    に書かれています。これはつまり、親以外のプロセスに
    シグナルを送る必要すらない、ということです。
    親プロセスに送ることができる 4 種類のシグナルがあります:
    TERM,
    HUP, 
    USR1,
    WINCH
    です。これらの説明については続きをご覧下さい。
    

    
    親プロセスにシグナルを送るには、
    次のようなコマンドを発行して下さい:
    


    kill -TERM `cat /usr/local/apache2/logs/httpd.pid`
    

    
    httpd プロセスにシグナルを送る 2 番目の方法は
    -k というコマンドライン引数を使用することです。
    下で説明されているように、stop, restart, 
    graceful, graceful-stop を指定できます。
    これらは httpd の引数ですが、
    制御用のスクリプト apachectl はそれらの引数をそのまま
    httpd に渡します。
    

    
    httpd にシグナルを送った後、
    実行状況を次のコマンドで読むことができます:
    


    tail -f /usr/local/apache2/logs/error_log
    
    
    ここに挙げた例は、各自の
    ServerRoot
    と
    PidFile
    の設定に適合するように適宜修正して下さい。
    

    top
    

    

    急な停止
    


    シグナル: TERM
    

    apachectl -k stop
    

    

    
    TERM あるいは stop 
    シグナルを親プロセスに送ると、即座に子プロセス全てを kill しようとします。
    子プロセスを完全に kill し終わるまでに数秒かかるかもしれません。
    その後、親プロセス自身が終了します。
    処理中のリクエストは全て停止され、もはやリクエストに対する
    応答はされません。
    

    top
    

    

    緩やかな再起動
    


    シグナル: USR1
    

    apachectl -k graceful
    

    

    
    親プロセスは USR1 あるいは graceful
    シグナルを受け取ると、子プロセスに現在のリクエストの処理の後に終了する
    (あるいは何もしていなければすぐに終了する)
    ように助言します。
    親プロセスは設定ファイルを再読込して、ログファイルを開き直します。
    子プロセスが徐々になくなるに従って、
    新しい世代の設定による子プロセスに置き換えていきます。
    そして、これらが新たなリクエストに即座に応答し始めます。
    

    
    このコードは常に
    MPM のプロセス制御ディレクティブの設定を重視しますので、
    クライアントのリクエストを扱うプロセスとスレッドの数を再起動の処理中も
    適切な値に維持されます。。また、次のようにして
    StartServers
    を守ります:
    少なくとも 1 秒後に StartServers 個の新しい子プロセスが
    生成されていなければ、その数になるように適宜プロセスを生成します。
    この挙動は現在の負荷に対して適切な子プロセスの数と
    StartServers パラメータでの
    希望の数の両方を維持しようとしています。
    

    
    mod_status を
    使用している場合は、USR1 シグナルが送られた際に
    サーバ統計がゼロに設定されないことに
    注意してください。
    サーバが新しいリクエストに応答不能な時間を最小にするように
    (リクエストは OS によってキューに追加されるので絶対に紛失はしません)、
    また同時に、希望のチューニングパラメータを守るように
    コードは書かれています。
    このようにするために、世代をまたがった全子プロセスの追跡に使われている
    スコアボードを維持しなければなりません。
    

    
    status モジュールは、緩やかな再起動以前から開始して
    リクエストに応答し続けている子プロセスを特定するために、
    G を使うこともします。
    

    
    現在、USR1 を使うログ移動スクリプトでは、
    再起動前の子プロセスがログを書き終わったことを確証する方法が
    ありません。古いログに対して何かする前に、
    USR1 シグナルを送った後いくらか適当な時間待つことを
    提案します。例えば、帯域の狭い通信路のユーザのリクエストのほとんどが 10 
    分以下で完了しているということが分かっていれば、
    古いログに何かする前に 15 分待つということです。
    

    
    再起動が発行されると設定ファイルの構文チェックがまず走り、
    設定ファイルに (構文上の) 誤りがないかチェックされます。
    誤りがあった場合エラーメッセージでその旨が示され、サーバは再起動されません。
    こうすることでサーバが終了しているけれども再起動できないという状況を
    防ぎ、サーバが機能不全な状態になるのを防いでいます。
    

    
    ただしこれでもサーバが正しく再起動することは保証されません。
    設定ファイルの意味的な内容を構文と同様に検証したい場合は、
    非 root ユーザで httpd を起動しようとすればわかります。
    もしエラーがなければ、ソケットやログを開こうとして
    root でないため
    (もしくは実行中の httpd
    が既に必要なポートにバインドしているため)
    に失敗するでしょう。
    これ以外の理由で起動に失敗したのであれば、
    それは設定ファイルのエラーで、
    緩やかな再起動を行う前にその誤りを修正しなければなりません。
    
    
    

    top
    

    

    急な再起動
    


    シグナル: HUP
    

    apachectl -k restart
    

    

    
    HUP あるいは restart シグナルを親プロセスに送ると、
    TERM と同様に子プロセスを kill しますが、
    親プロセスは終了しません。
    設定ファイルを再読込して、ログファイル全てを開き直します。
    その後、新しい子プロセスを起動して応答を続けます。
    

    
    mod_status
    を使っている場合は、HUP が送られた場合に
    サーバ統計がゼロに設定されることに注意してください。
    

    
    graceful 再起動時は、再起動前に構文チェックが行われます。
    もし構文エラーがあればその旨が示され、再起動は行われません。
    

    top
    

    

    緩やかな停止
    


    Signal: WINCH
    

    apachectl -k graceful-stop
    

    

    
    WINCH や graceful-stop シグナルを受け取ると、
    親プロセスは子プロセスに現在処理中のリクエストの後に終了する
    (あるいは処理中のものが何もなければ直ちに終了する)
    ようにアドバイスします。
    その後親プロセスは PidFile
    を削除し、ポートでの Listen を全て停止します。
    親プロセスはどの子プロセスがリクエスト処理中かを監視し続けています。
    全ての子プロセスが終了するか
    GracefulShutdownTimeout
    で設定した時間が過ぎると、親プロセスも終了します。
    タイムアウトに達した場合、残りの子プロセスには TERM
    シグナルが送信され強制的に終了されます。
    
    
    
    "graceful" 状態の場合 TERM シグナルを受け取ると、
    親プロセスも子プロセスもすぐに終了します。しかしながら
    PidFile
    が削除されてしまっているので、apachectl
    や httpd にこのシグナルを送ることはできません。
    

    
    graceful-stop を使うとまったく同一に設定された
    複数の httpd を同時に実行することができます。
    httpd を緩やかにアップグレードするのにはとても便利ですが、
    設定ファイルによってはデッドロックやレースコンディションを
    引き起こすこともあります。
    

    
    ディスク上のファイルを使うもの、たとえばロックファイル
    (Mutex) や Unix ソケットファイル
    (ScriptSock) 
    などはサーバの PID を含めて管理されていて、
    共存できるよう注意が払われています。
    しかしその他設定ディレクティブやサードパーティ製のモジュール、
    CGI ユーティリティのパーシステント層などで
    ディスク上にロックファイルや状態管理ファイルを
    使っている場合は、実行されている複数の httpd
    が互いに衝突しないように気をつけなければなりません。
    

    
    rotatelogs 形式のパイプを使ったログといった、
    その他潜在的なレースコンディションについても注意しなければなりません。
    複数の rotatelogs が同じファイルを同時に
    rotate しようとすると、互いにログファイルを破壊してしまいます。

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    


    
    Apache は HTTP/1.1 の規格に記述されているコンテントネゴシエーションを
    サポートしています。
    ブラウザにより提供されたメディアタイプ、
    言語、文字セット、エンコーディングの優先傾向に基づいて、
    最適なリソースの表現を選択できます。
    また、不完全なネゴシエーション情報を送ってくるブラウザからのリクエストを
    もっと賢く取り扱えるよう、いくつか機能も実装してあります。
    

    
    コンテントネゴシエーションは
    mod_negotiation
    モジュールによって提供されていて、デフォルトで組み込まれています。
    

    


    top
    

    

    コンテントネゴシエーションについて
    

    
    リソースは、幾つか異なった表現で利用できる場合があります。
    例えば、異なる言語や異なるメディアタイプ、
    またはそれらの組み合わせで利用できるかも知れません。
    もっとも適した選択をする方法の一つには、インデックスページを
    ユーザに見せて、ユーザに選んでもらう方法があります。
    しかし、サーバが自動的に選ぶことができる場合が多くあります。
    これは、ブラウザがリクエスト毎に、
    どの表現を嗜好するかという情報を送ることで動作しています。
    例えばブラウザは、可能ならフランス語で情報を見たい、
    不可能ならその代わりに英語でもよいと、
    自分の嗜好を知らせることができます。
    ブラウザはリクエストのヘッダで自分の優先傾向を知らせます。
    フランス語のみの表現を要求する場合は、ブラウザは次を送ります。
    


    Accept-Language: fr
    

    
    この優先傾向は、選択可能な表現が存在して、
    言語によって様々な表現がある場合にのみ適用される
    ということに注意してください。
    

    
    もっと複雑なリクエストの例を挙げましょう。
    このブラウザはフランス語と英語を受け付ける、しかしフランス語を好む、
    そして様々なメディアタイプを受け付けるが、
    プレインテキストや他のタイプよりは HTML を好む、
    他のメディアタイプよりは GIF や JPEG を好む、しかし最終手段として
    他のメディアタイプも受け付ける、と設定されています。
    


    
  Accept-Language: fr; q=1.0, en; q=0.5
    
  Accept: text/html; q=1.0, text/*; q=0.8, image/gif; q=0.6, image/jpeg; q=0.6, image/*; q=0.5, */*; q=0.1

    

    
    Apache は HTTP/1.1 規格で定義されている 'server
    driven' コンテントネゴシエーションをサポートしています。
    Accept, Accept-Language, 
    Accept-Charset, Accept-Encoding
    リクエストヘッダを完全にサポートしています。Apache は
    'transparent' コンテントネゴシエーションもサポートしていますが、
    これは RFC 2295 と RFC 2296 で定義されている試験的な
    ネゴシエーションプロトコルです。
    これらの RFCで定義されている 'feature negotiation'
    はサポートしていません。
    

    
    リソースとは URI
    で特定される概念上のもののことです (RFC 2396)。 Apache
    のような HTTP サーバは、その名前空間の中での
    リソースの表現へのアクセスを提供します。
    それぞれの表現は
    定義されたメディアタイプ、文字セット、エンコーディング等の
    付属した、バイト列の形式です。
    それぞれのリソースはある時点で 0 個、1 個、それ以上の表現と
    関連付けられる可能性があります。複数の表現が利用できる場合は、
    リソースはネゴシエーション可能であるとされ、
    個々の表現は variant と呼ばれます。
    ネゴシエーション可能なリソースの variant が異なる、
    その状態を指して、
    ネゴシエーションの次元と呼びます。
    

    top
    

    

    Apache におけるネゴシエーション
    

    
    リソースをネゴシエーションするためには、
    サーバは variant それぞれについての情報を知っておく必要があります。
    これは以下の二つの方法のどちらかで行われます。
    

    
      
      
    • タイプマップ
      (すなわち *.var ファイル)
      を使う方法。 これは variant
      を明示的に挙げているファイルを指定します。
      • 

      
    • 'Multiviews'
      を使って、サーバが暗黙の内にファイル名にパターン照合を
      行なってその結果から選択する方法。
      • 
    
    

   
    type-map ファイルを使う
    

    
    タイプマップは type-map ハンドラ
    (もしくは、古い Apache
    の設定と下位互換である MIME タイプ
    application/x-type-map)
    に関連付けられたドキュメントです。
    この機能を使うためには、あるファイルの拡張子を
    type-map
    として定義するようなハンドラを、
    設定ファイル中に置く必要があることに注意してください。
    これは
    


    AddHandler type-map .var
    

    
    をサーバ設定ファイル中に書くことが一番良い方法です。
    

    
    タイプマップファイルは記述するリソースと同じ名前を持っていて、
    利用可能な variant それぞれのエントリを持っている必要があります。
    そして、このエントリは連続した HTTP のヘッダ行で構成されます。
    異なる variant のためのエントリは空行で区切られています。
    エントリ中に空行が複数あってはいけません。
    習慣的には、マップファイルは全体を結合したもののエントリから始まります
    (しかしこれは必須ではなく、あったとしても無視されるものです)。
    次に例を示します。このファイルはリソース foo 
    を記述しているので、foo.var という名前になります。
    


    
  URI: foo
    

    
  URI: foo.en.html
    
  Content-type: text/html
    
  Content-language: en
    

    
  URI: foo.fr.de.html
    
  Content-type: text/html;charset=iso-8859-2
    
  Content-language: fr, de
    

    
    
    たとえ MultiViews を使用するようになっていたとしても、
    ファイル名の拡張子よりタイプマップの方が優先権を持つということにも
    注意してください。
    variant の品質が違うときは、この画像のように (JPEG, GIF, ASCII
    アートがあります) メディアタイプの "qs"
    パラメータで指定されます。
    


    
  URI: foo
    

    
  URI: foo.jpeg
    
  Content-type: image/jpeg; qs=0.8
    

    
  URI: foo.gif
    
  Content-type: image/gif; qs=0.5
    

    
  URI: foo.txt
    
  Content-type: text/plain; qs=0.01
    

    

    
    qs 値の範囲は 0.000 から 1.000 です。qs 値が
    0.000 の variant は決して
    選択されないことに注意してください。'qs' 値のない variant
    は qs 値 1.0 を 与えられます。qs
    パラメータはクライアントの能力に関係無く、他の variant と
    比較したときの variant
    の相対的な「品質」を示します。
    例えば、写真を表現しようとしているときは JPEG
    ファイルの方が普通は ASCII
    ファイルよりも高い品質になります。しかし、リソースが元々
    ASCII アートで表現されているときは、ASCII ファイルの
    方が JPEG ファイルよりも高い品質になります。このように、qs
    は 表現されるリソースの性質によって variant
    毎に特有の値を取ります。
    

    
    認識されるヘッダの一覧は
    mod_negotiation
    ドキュメントにあります。
    



    Multiviews
    

    
    MultiViews はディレクトリ毎のオプションで、
    httpd.confファイルの
    <Directory>, 
    <Location>, 
    <Files>
    セクション中や、(AllowOverride
    が適切な値に 設定されていると) .htaccess
    ファイルで Options
    ディレクティブによって設定することができます。
    Options All は
    MultiViews
    をセットしないことに注意してください。明示的に
    その名前を書く必要があります。
    

    
    MultiViews の効果は以下のようになります:
    サーバが /some/dir/foo
    へのリクエストを受け取り、/some/dir で
    MultiViews が有効であって、
    /some/dir/foo が存在しない場合、
    サーバはディレクトリを読んで foo.*
    にあてはまる全てのファイルを探し、
    事実上それらのファイルをマップするタイプマップを作ります。
    そのとき、メディアタイプとコンテントエンコーディングは、そのファイル名を
    直接指定したときと同じものが割り当てられます。
    それからクライアントの要求に一番合うものを選びます。
    

    
    サーバがディレクトリの索引を作ろうとしている場合、
    MultiViews
    は DirectoryIndex
    ディレクティブで指定されたファイルを探す過程にも
    適用されます。設定ファイルに
    

    DirectoryIndex index
    
    
    が書かれていて、index.html と
    index.html3 が
    両方存在していると、サーバはその中からどちらかを適当に選びます。
    もしその両方が存在せずに index.cgi
    が存在していると、 サーバはそれを実行します。
    

    
    もしディレクトリを読んでいる際に、
    文字セット、コンテントタイプ、言語、エンコーディングを
    指定するための mod_mime 
    で認識できる拡張子を持たないファイルが見つかると、結果は
    MultiViewsMatch
    ディレクティブの設定に依存します。このディレクティブは
    ハンドラ、フィルタ、他のファイル拡張子タイプのどれが
    MultiViews ネゴシエーションで使用できるかを決定します。
    


    top
    

    

    ネゴシエーション方法
    

    
    Apache はリソースの variant の一覧を、タイプマップファイルか
    ディレクトリ内のファイル名からかで取得した後、
    「最適な」 variant を決定するために二つの方法の
    どちらかを起動します。
    Apache のコンテントネゴシエーションの機能を使うために、
    どのようにしてこの調停が行われるか詳細を知る必要はありません。
    しかしながら、この文書の残りでは関心のある人のために、
    使用されている方法について説明しています。
    

    
    ネゴシエーション方法は二つあります。
    

    
      
      
    1. 通常は Apache のアルゴリズムを用いた Server
      driven negotiation が使用されます。Apache
      のアルゴリズムは後に詳細に説明されています。
      このアルゴリズムが使用された場合、Apache
      はより良い結果になるように、特定の次元において品質の値を
      「変える」ことができます。Apache
      が品質の値を変える方法は後で詳細に説明されています。
      2. 

      
    2. RFC 2295
      で定義されている機構を用いてブラウザが特に指定した場合、
      transparent content negotiation
      が使用されます。このネゴシエーション方法では、「最適な」
      variant の決定をブラウザが完全に制御することができます。
      ですから、結果はブラウザが使用しているアルゴリズムに依存します。
      Transparent negotiation の処理の過程で、ブラウザは RFC 2296
      で 定義されている 'remote variant selection algorithm'
      を実行するように頼むことができます。
      3. 
    
    


    ネゴシエーションの次元
    

    
    
      
      
    
        次元

        説明
      
    

      
    
        メディアタイプ

        ブラウザは Accept
	ヘッダフィールドで優先傾向を指定します。
	アイテムそれぞれは、関連した品質数値を持つことができます。
	variant の説明も品質数値を持つことができます
	("qs" パラメータをご覧下さい)。
      
    

      
    
        言語

	ブラウザは Accept-Language
	ヘッダフィールドで優先傾向を指定します。
	要素それぞれに品質数値を持たせることができます。
	variants は 0 か 1 つかそれ以上の言語と
	関連づけることができます。
      
    

      
    
        エンコーディング

	ブラウザは Accept-Encoding
	ヘッダフィールドで優先傾向を指定します。
	要素それぞれに品質数値を持たせることができます。
      
    

      
    
        文字セット

	ブラウザは Accept-Charset
	ヘッダフィールドで優先傾向を指定します。
	要素それぞれに品質数値を持たせることができます。
	variant はメディアタイプのパラメータとして文字セットを
	指定することもできます。
      
    
    
    



    Apache ネゴシエーションアルゴリズム
    

    
    ブラウザに返す「最適な」variant を (もしあれば) 選択するように
    Apache は次のアルゴリズムを使うことができます。
    このアルゴリズムを設定により変更することはできません。
    次のように動作します:
    

    
      
      
    1. まずはじめに、ネゴシエーションの次元それぞれについて適切な
      Accept* ヘッダフィールドを調べ、
      variant それぞれに品質を割り当てます。
      もしある次元の Accept* ヘッダでその variant
      が許容できないことが示されていれば、それを削除します。
      variant が一つも残っていなければ、ステップ 4 に行きます。
      2. 

      
    2. 
	消去法で「最適な」 variant を選びます。
	次のテストが順番に適用されます。
	テストで選択されなかった variant は削除されていきます。
	テスト後 variant が一つだけ残っていれば、それを最適なものとして
	ステップ 3 に進みます。
	複数 variant が残っていれば、次のテストに進みます。

        
        
	  
      1. variant のメディアタイプの品質数値と Accept
	  ヘッダの品質数値との積を計算して、最高値の variant
	  を選びます。
        2. 

	  
      2. 言語品質数値が最高の variant を選びます。
        3. 

	  
      3. (もしあれば) Accept-Language ヘッダの言語順か、
	  (もしあれば)
	  LanguagePriority 
	  ディレクティブの言語順で最適な言語の variant を選びます。
        4. 

	  
      4. 最高「レベル」のメディアパラメータ
	  (text/html メディアタイプのバージョンを与えるために使われます)
	  を持つ variant を選びます。
        5. 

	  
      5. Accept-Charset ヘッダ行で与えられている最高の文字セット
	  メディアパラメータを持つ variant を選びます。
	  明示的に除外されていない限り、ISO-8859-1
	  が許容されるようになっています。
	  text/* メディアタイプであるけれども
	  特定の文字セットに明示的に関連づけられているわけではない
	  variant は ISO-8859-1 であると仮定されます。
        6. 

	  
      6. ISO-8859-1 ではない文字セットメディアパラメータと
	  関連づけられている variant を選びます。
	  そのような variant がない場合は、代わりに全ての
	  variant を選びます。
        7. 

	  
      7. 最適なエンコーディングの variant を選びます。
	  もし user-agent が許容するエンコーディングがあれば、
	  その variant のみを選びます。
	  そうではなく、もしエンコードされたものとそうでない
	  variant が混ざって存在していたらエンコードされていない
	  variant のみを選びます。
	  variant が全部エンコードされているか
	  variant が全部エンコードされていないという場合は、
	  全ての variant を選びます。
        8. 

	  
      8. 内容の最も短い variant を選びます。
        9. 

	  
      9. 残っている variant の最初のものを選びます。
	  タイプマップファイルの最初にリストされているか、
	  variant がディレクトリから最初に読み込まれる時に
	  ASCII順でソートしてファイル名が先頭になったか、のどちらかです。
        10. 
        
      
      
      3. 

      
    3. アルゴリズムを使って一つの「最適な」variant を選びましたので、
      それを応答として返します。ネゴシエーションの次元を指定するために
      HTTP レスポンスヘッダ Vary が設定されます
      (リソースのキャッシュをする時に、
      ブラウザやキャッシュはこの情報を使うことができます)。
      以上で終わり。
      4. 

      
    4. ここに来たということは、variant が一つも選択されなかった
      (ブラウザが許容するものがなかったため) ということです。
      406 ステータス ("No Acceptable representation" を意味する)
      が、利用可能な variant のリストのついた HTML 
      ドキュメントとともに返されます。
      相違の次元を示す HTTP Vary ヘッダも設定されます。

    品質の値を変える
    

    
    上記の Apache ネゴシエーションアルゴリズムの厳格な解釈で
    得られるであろう値から、Apache は品質数値を時々変えます。
    これは、このアルゴリズムで完全ではない、あるいは正確でない情報を送る
    ブラウザ向けによりよい結果を得るために行われます。
    かなりポピュラーなブラウザで、もしないと間違った variant
    を選択する結果になってしまうような Accept
    ヘッダ情報を送るものもあります。
    ブラウザが完全で正しい情報を送っていれば、
    この数値変化は適用されません。
    


    メディアタイプとワイルドカード
    

    
    Accept: リクエストヘッダはメディアタイプの優先傾向を指定します。
    これはまた、"image/*" や "*/*"
    といった「ワイルドカード」メディアタイプを含むことができます。
    ここで * は任意の文字列にマッチします。
    ですから、次の:
    


    Accept: image/*, */*
    

    
    を含むリクエストは、"image/" ではじまるタイプ全てが許容できる、
    そして他のどんなタイプも許容できる
    (この場合はじめの "image/*" は冗長になります)
    ことを示します。
    扱うことのできる明示的なタイプに加えて、機械的に
    ワイルドカードを送るブラウザもあります。例えば:
    


    
  Accept: text/html, text/plain, image/gif, image/jpeg, */*

    
    
    こうすることの狙いは、明示的にリストしているタイプが優先されるけれども、
    異なる表現が利用可能であればそれでも良い、ということです。
    しかしながら、上の基本的なアルゴリズムでは、
    */* ワイルドカードは他の全てのタイプと全く同等なので優先されません。
    ブラウザは */* にもっと低い品質 (優先) 
    値を付けてリクエストを送るべきなのです。例えば:
    

    
  Accept: text/html, text/plain, image/gif, image/jpeg, */*; q=0.01

    
    
    明示的なタイプには品質数値が付けられていませんので、
    デフォルトの 1.0 (最高値) の優先になります。
    ワイルドカード */* は低い優先度 0.01 を与えられているので、
    明示的にリストされているタイプに合致する variant がない場合にのみ、
    他のタイプが返されます。
    

    
    もし Accept: ヘッダが q 値を全く含んでいなければ、
    望みの挙動をするために、
    Apache は "*/*" があれば 0.01 の q 値を設定します。
    また、"type/*" の形のワイルドカードには 0.02 の q 値を設定します
    (ですからこれらは "*/*" のマッチよりも優先されます)。
    もし Accept: ヘッダ中のメディアタイプのどれかが q
    値を含んでいれば、これらの特殊な値は適応されず、
    正しい情報を送るブラウザからのリクエストは期待通りに
    動作するようになります。
    



    言語ネゴシエーションの例外処理
    

    
    Apache 2.0 では新たに、言語ネゴシエーションが適合するものを
    見つけるのに失敗した時に、優雅にフォールバックできるような
    ネゴシエーションアルゴリズムが幾つか追加されました。
    

    
    サーバのページをクライアントがリクエストしたけれども、
    ブラウザの送ってきた Accept-Language に合致するページが一つも
    見つからなかった場合に、サーバは "No Acceptable Variant"
    か "Multiple Choices" レスポンスをクライアントに返します。
    これらのエラーメッセージを返さないように、
    このような場合には Apache が Accept-Language を無視して、
    クライアントのリクエストに明示的には合致しないドキュメントを
    提供するように設定できます。
    ForceLanguagePriority
    ディレクティブは、これらのエラーの一つか両方をオーバーライドするために
    使用できて、
    LanguagePriority
    ディレクティブの内容を使ってサーバの判断を代行するようにできます。
    

    
    サーバは他に適合するものが見つからなければ、
    言語サブセットで適合するものを試そうともします。
    例えばクライアントが英国英語である en-GB 言語で
    ドキュメントをリクエストした場合、サーバは HTTP/1.1
    規格では、単に en とマークされているドキュメントを
    マッチするものとすることは通常は許されていません。
    (英国英語は理解できるけど一般的な英語は理解できないという読み手は
    考えられないので、Accept-Language ヘッダで en-GB 
    を含んで en を含まないのはほぼ確実に設定の間違いである、
    ということに注意してください。
    ですが不幸なことに、多くのクライアントではデフォルトで
    このような設定になっています。)
    しかしながら、他の言語にはマッチせず、"No Acceptable Variants"
    エラーを返したり、
    LanguagePriority
    にフォールバックしようとしているときは、
    サブセット指定を無視して、en-GB を en
    にマッチします。
    Apache はクライアントの許容言語リストに暗黙に
    非常に低い品質値の親言語を加えることになります。
    しかし、クライアントが "en-GB; q=0.9, fr; q=0.8" とリクエストして、
    サーバが "en" と "fr" と設計されたドキュメントを持っている場合は、
    "fr" ドキュメントが返されることに注意してください。
    このような処理は、HTTP 1.1 規格との整合性を維持して、
    適切に設定されたクライアントともきちんと動作するために
    必要です。
    

    
    より高度なテクニック (Cookie や特殊な URL パス等)
    においてもユーザの言語選択をサポートするため、
    Apache 2.0.47 からは、mod_negotiation
    が環境変数 prefer-language
    を認識するようになりました。
    この変数が存在して、適切な言語タグが代入されているのであれば、
    mod_negotiation は合致する variant
    を選択しようとします。合致するものが無ければ、
    通常のネゴシエーション手順が適用されます。
    

    
    Example
    
      SetEnvIf Cookie "language=(.+)" prefer-language=$1
    
      Header append Vary cookie 
    
    


    top
    

    

    Transparent Content Negotiation
の拡張
     


    Apache は transparent content negotiation プロトコル
(RFC 2295) を次のように拡張しています。
特定のコンテントエンコーディングのみが利用可能である variant 
に印を付けるために、新たに {encoding ..} 
要素を variant リスト中に使っています。
リスト中のエンコードされた variant を認識し、
Accept-Encoding リクエストヘッダに従って許容される
エンコードをもった variant は、どれでも候補 variant
として使用するように、
RVSA/1.0 アルゴリズム (RFC 2296) の実装が拡張されました。
RVSA/1.0 の実装では、最適な variant が見つかるまで、
計算した品質数値は小数点以下 5 桁まで丸めません。

    リンクと名前の変換に関する注意点
    

    
    言語ネゴシエーションを使っている場合は、
    ファイルが一つ以上の拡張子を持てて、
    拡張子の順番は通常は考慮されない
    (詳細は mod_mime 
    を参照) ので、
    幾つかの異なる名前の変換を選べることになります。
    

    
    典型的なファイルでは、MIME タイプ拡張子 (例えば
    html) を持っていて、エンコーディング拡張子
    (例えば gz) を持っているかもしれなくて、
    このファイルに異なる言語 variant を用意していれば、
    もちろん言語拡張子 (例えば en)
    を持っているでしょう。
    

    
    例:
    

    
      
      
    • foo.en.html
      • 

      
    • foo.html.en
      • 

      
    • foo.en.html.gz
      • 
    
    

    
    ファイル名と、それに対して使えるリンクと使えないリンクの例です:
    

    
    
      
      
    
        ファイル名

        使えるリンク

        使えないリンク
      
    

      
    
        foo.html.en

        foo
    
         foo.html    		

        -
      
    

      
    
        foo.en.html

        foo

        foo.html
      
    

      
    
        foo.html.en.gz

        foo
    
         foo.html    		

        foo.gz
    
         foo.html.gz    		
      
    

      
    
        foo.en.html.gz

        foo

        foo.html
    
         foo.html.gz
    
         foo.gz    		
      
    

      
    
        foo.gz.html.en

        foo
    
         foo.gz
    
         foo.gz.html    		

        foo.html
      
    

      
    
        foo.html.gz.en

        foo
    
         foo.html
    
         foo.html.gz    		

        foo.gz
      
    
    
    

    
    上の表を見て、拡張子なしのリンク (例えば foo) 
    がいつでも使えることに気が付くでしょう。
    この利点は、ドキュメントとして応答するファイルの
    実際のファイルタイプを隠蔽して、リンクの参照を変更することなく
    後からファイルを変更できる、
    例えば html から shtml
    に、あるいは cgi に変更できる点です。
    

    
    リンクに MIME タイプを使い続けたい (例えば
    foo.html)時は、言語拡張子は
    (エンコーディング拡張子もあればそれも含めて)
    MIME タイプ拡張子の右側になければなりません
    (例えば foo.html.en)。

    キャッシュに関する注意事項
    

    
    キャッシュが一つの表現を保存しているときは、
    リクエスト URL と関連づけられています。
    次にその URL がリクエストされた時に、キャッシュは
    保存されている表現を使用できます。しかし、
    リソースがサーバでネゴシエーション可能であれば、
    最初のリクエストでキャッシュされて続くキャッシュヒットでは
    間違った応答を返してしまうということになりかねません。
    これを防ぐために、Apache はコンテントネゴシエーションの
    後に返された応答全てに、HTTP/1.0 クライアントでは
    キャッシュ不可能の印をつけます。
    また、ネゴシエーションされた応答のキャッシュを可能にする
    HTTP/1.1 プロトコルの機能も Apache はサポートします。
    

    
    HTTP/1.0 準拠のクライアントからのリクエストに対しては、
    (ブラウザであろうとキャッシュであろうと)
    ネゴシエーションを受けた応答のキャッシュを許すために、
    CacheNegotiatedDocs
    ディレクティブを使用できます。
    このディレクティブは、サーバ設定ファイルやバーチャルホストに書くことができ、
    引数をとりません。
    HTTP/1.1 クライアントからのリクエストには効力を持ちません。
    

    
    HTTP/1.1 クライアントに対しては、レスポンスのネゴシエーション次元
    を示すために Vary HTTP レスポンスヘッダを送ります。
    キャッシュは、これを使って後続のリクエストに対してローカルコピーで応答できるか
    どうかを決定できます。
    ネゴシエーション次元とは関係なしにローカルコピーの使用を優先するようにするには、
    force-no-vary 環境変数を
    設定します。

    La fonctionnalité suEXEC permet
    l'exécution des programmes CGI et
    SSI sous un utilisateur autre que celui sous
    lequel s'exécute le serveur web qui appelle ces programmes.
    Normalement, lorsqu'un programme CGI ou SSI est lancé, il
    s'exécute sous le même utilisateur que celui du serveur web qui
    l'appelle.
    

    
    Utilisée de manière appropriée, cette fonctionnalité peut
    réduire considérablement les risques de sécurité encourus
    lorsqu'on autorise les utilisateurs à développer et faire
    s'exécuter des programmes CGI ou SSI de leur cru. Cependant, mal
    configuré, suEXEC peut causer de nombreux problèmes et même créer
    de nouvelles failles dans la sécurité de votre ordinateur. Si
    vous n'êtes pas familier avec la gestion des programmes
    setuid root et les risques de sécurité qu'ils comportent,
    nous vous recommandons vivement de ne pas tenter
    d'utiliser suEXEC.
    
  
    


    top
    

    

    Avant de commencer
    

    
    Avant de foncer tête baissée dans la lecture de ce document,
    vous devez tenir compte de certaines hypothèses concernant vous-même
    et l'environnement dans lequel vous allez utiliser suexec.
    

    
    Premièrement, vous devez utiliser un système d'exploitation
    UNIX ou dérivé, capable d'effectuer des opérations
    setuid et setgid. Tous les
    exemples de commande sont donnés en conséquence. D'autres
    plates-formes, même si elles supportent suEXEC, peuvent
    avoir une configuration différente.
    

    
    Deuxièmement, vous devez être familier avec les concepts de base
    relatifs à la sécurité de votre ordinateur et son administration.
    Ceci implique la compréhension des opérations
    setuid/setgid et des différents effets qu'elles
    peuvent produire sur votre système et son niveau de sécurité.
    

    
    Troisièmement, vous devez utiliser une version
    non modifiée du code de suEXEC. L'ensemble du
    code de suEXEC a été scruté et testé avec soin par les développeurs
    et de nombreux bêta testeurs. Toutes les précautions ont été prises
    pour s'assurer d'une base sûre de code non seulement simple, mais
    aussi solide. La modification de ce code peut causer des problèmes
    inattendus et de nouveaux risques de sécurité. Il est
    vivement recommandé de ne pas modifier le code de
    suEXEC, à moins que vous ne soyez un programmeur spécialiste des
    particularités liées à la sécurité, et souhaitez partager votre
    travail avec l'équipe de développement du serveur HTTP Apache afin
    de pouvoir en discuter.
    

    
    Quatrièmement et dernièrement, l'équipe de développement du
    serveur HTTP Apache a décidé de ne
    PAS inclure suEXEC dans l'installation par défaut
    d'Apache httpd. Pour pouvoir mettre en oeuvre suEXEC, l'administrateur
    doit porter la plus grande attention aux détails. Après avoir bien
    réfléchi aux différents points de la configuration de suEXEC,
    l'administrateur peut l'installer selon les méthodes classiques.
    Les valeurs des paramètres de configuration doivent être
    déterminées et spécifiées avec soin par l'administrateur, afin de
    maintenir la sécurité du système de manière appropriée lors de
    l'utilisation de la fonctionnalité suEXEC. C'est par le biais de
    ce processus minutieux que nous espérons réserver
    l'installation de suEXEC aux administrateurs prudents et
    suffisamment déterminés à vouloir l'utiliser.
    

    
    Vous êtes encore avec nous ? Oui ? Bien.
    Alors nous pouvons continuer !
    

    top
    

    

    Modèle de sécurité de suEXEC
    

    
    Avant d'installer et configurer suEXEC, nous allons tout d'abord
    décrire le modèle de sécurité que vous êtes sur le point
    d'implémenter. Vous devriez ainsi mieux comprendre ce qui se passe
    vraiment à l'intérieur de suEXEC et quelles précautions ont été
    prises pour préserver la sécurité de votre système.
    

    
    suEXEC est basé sur un programme "conteneur"
    (wrapper) setuid qui est appelé par le serveur HTTP Apache principal.
    Ce conteneur est appelé quand une requête HTTP concerne
    un programme CGI ou SSI que l'administrateur
    a décidé de faire s'exécuter
    sous un utilisateur autre que celui du serveur principal.
    Lorsqu'il reçoit une telle requête, Apache httpd fournit au conteneur
    suEXEC le nom du programme, ainsi que les identifiants utilisateur
    et groupe sous lesquels le programme doit s'exécuter.
    

    
    Le conteneur effectue ensuite les vérifications suivantes afin
    de déterminer la réussite ou l'échec du processus -- si une seule
    de ces conditions n'est pas vérifiée, le programme journalise
    l'erreur et se termine en retournant un code d'erreur, sinon il
    continue :
    

    
      
      
    1. 
        L'utilisateur qui exécute le conteneur est-il un
	utilisateur valide de ce système ?

        
      
          Ceci permet de s'assurer que l'utilisateur qui exécute le
	  conteneur est vraiment un utilisateur appartenant au système.
        
      
     
      2. 

     
    2. 
        Le conteneur a-t-il été appelé avec un nombre
	d'arguments correct ?

        
      
          Le conteneur ne s'exécutera que si on lui fournit un nombre
	  d'arguments correct. Le serveur HTTP apache sait quel est le
	  bon format des arguments. Si le conteneur ne reçoit pas un
	  nombre d'arguments correct, soit il a été modifié,
	  soit quelque chose ne va pas dans la portion suEXEC de
	  votre binaire Apache httpd.
        
      
      
      3. 

      
    3. 
        Cet utilisateur valide est-il autorisé à exécuter le
	conteneur ?

        
      
          Cet utilisateur est-il celui autorisé à exécuter le
	  conteneur ? Un seul utilisateur (celui d'Apache) est
	  autorisé à exécuter ce programme.
        
      
      
      4. 

      
    4. 
        Le chemin du programme CGI ou SSI cible est-il
	non sûr ?

        
      
          Le chemin du programme CGI ou SSI cible débute-t-il par un
	  '/' ou contient-il une référence arrière '..' ? Ceci est
	  interdit ; le programme CGI ou SSI cible doit se trouver dans
	  la hiérarchie de la racine des documents de suEXEC (voir
	  --with-suexec-docroot=DIR ci-dessous).
        
      
      
      5. 

      
    5. 
        Le nom utilisateur cible est-il valide ?

        
      
          L'utilisateur cible existe-t-il ?
        
      
      
      6. 

      
    6. 
        Le nom du groupe cible est-il valide ?

        
      
          Le groupe cible existe-t-il ?
        
      
      
      7. 

      
    7. 
        L'utilisateur cible n'est-il PAS
	superutilisateur ?


        
      
          suEXEc ne permet pas à
	  root d'exécuter des programmes CGI/SSI.
        
      
      
      8. 

      
    8. 
        Le numéro de l'identifiant de l'utilisateur cible
	est-il SUPERIEUR au numéro d'identifiant
	minimum ?

        
      
          Le numéro d'identifiant utilisateur minimum est défini à
	  l'exécution du script configure. Ceci vous permet de définir
	  le numéro d'identifiant utilisateur le plus bas qui sera
	  autorisé à éxécuter des programmes CGI/SSI. En particulier,
	  cela permet d'écarter les comptes système.
        
      
      
      9. 

      
    9. 
        Le groupe cible n'est-il PAS le groupe
	superutilisateur ?

        
      
          Actuellement, suEXEC ne permet pas au groupe
	  root d'exécuter des programmes CGI/SSI.
        
      
      
      10. 

      
    10. 
         Le numéro d'identifiant du groupe cible est-il
	SUPERIEUR au numéro d'identifiant minimum ?

        
      
          Le numéro d'identifiant de groupe minimum est spécifié lors
	  de l'exécution du script configure. Ceci vous permet de
	  définir l'identifiant de groupe le plus bas possible qui sera
	  autorisé à exécuter des programmes CGI/SSI, et est
	  particulièrement utile pour écarter les groupes "système".
        
      
      
      11. 

      
    11. 
        Le conteneur peut-il obtenir avec succès l'identité
	des utilisateur et groupe cibles ?

        
      
          C'est ici que le programme obtient l'identité des utilisateur
	  et groupe cibles via des appels à setuid et setgid. De même,
	  la liste des accès groupe est initialisée avec tous les
	  groupes auxquels l'utilisateur cible appartient.
        
      
      
      12. 

      
    12. 
        Peut-on se positionner dans le répertoire dans dequel
	sont situés les programmes CGI/SSI ?

        
      
          S'il n'existe pas, il ne peut pas contenir de fichier. Et si
	  l'on ne peut pas s'y positionner, il n'existe probablement
	  pas.
        
      
      
      13. 

      
    13. 
        Le répertoire est-il dans l'espace web
	de httpd ?

        
      
          Si la requête concerne une portion de la racine du serveur,
	  le répertoire demandé est-il dans la hiérarchie de la racine
	  des documents de suEXEC ? Si la requête concerne un
	 UserDir, le répertoire demandé est-il dans
	  la hiérarchie du répertoire défini comme le répertoire
	  utilisateur de suEXEC (voir les
	  options de configuration de suEXEC) ?
        
      
      
      14. 

      
    14. 
        L'écriture dans le répertoire est-elle interdite pour
	un utilisateur autre que le propriétaire 

        
      
          Le répertoire ne doit pas être ouvert aux autres
	  utilisateurs ; seul l'utilisateur propriétaire doit pouvoir

    Ce sont les opérations standards effectuées par le modèle de
    sécurité du conteneur suEXEC. Il peut paraître strict et est
    susceptible d'imposer de nouvelles limitations et orientations
    dans la conception des programmes CGI/SSI, mais il a été développé
    avec le plus grand soin, étape par étape, en se focalisant sur
    la sécurité.
    

    
    Pour plus d'informations sur la mesure dans laquelle ce modèle
    de sécurité peut limiter vos possibilités au regard de la
    configuration du serveur, ainsi que les risques de sécurité qui
    peuvent être évités grâce à une configuration appropriée de suEXEC,

    Configurer et installer suEXEC
    

    
    C'est ici que nous entrons dans le vif du sujet.
    

    
    Options de configuration de suEXEC
    
    
    

    
    
      
    --enable-suexec
    

      
    Cette option active la fonctionnalité suEXEC qui n'est
      jamais installée ou activée par défaut. Au moins une option
      --with-suexec-xxxxx doit accompagner l'option
      --enable-suexec pour qu'APACI (l'utilitaire de
      configuration de la compilation d'Apache) accepte votre demande
      d'utilisation de la fonctionnalité suEXEC.
    

      
    --with-suexec-bin=PATH
    

      
    Le chemin du binaire suexec doit être codé en
      dur dans le serveur pour des raisons de sécurité. Cette option
      vous permet de modifier le chemin par défaut.
      Par exemple
      --with-suexec-bin=/usr/sbin/suexec
    

      
    --with-suexec-caller=UID
    

      
    L'utilisateur sous
      lequel httpd s'exécute habituellement. C'est le seul utilisateur
      autorisé à exécuter le wrapper suEXEC.
    

      
    --with-suexec-userdir=DIR
    

      
    Cette option définit le sous-répertoire de la hiérarchie des
      répertoires utilisateurs dans lequel l'utilisation
      de suEXEC sera autorisée. Tous les exécutables situés dans ce
      répertoire seront exécutables par suEXEC sous l'utilisateur
      cible ; ces programmes doivent donc être sûrs. Si vous utilisez
      une directive UserDir
      "simple" (c'est à dire ne contenant pas de
      "*"), l'option --with-suexec-userdir
      devra contenir la même valeur. SuEXEC ne fonctionnera pas
      correctement si la directive UserDir contient une valeur
      différente du répertoire home de l'utilisateur tel qu'il est
      défini dans le fichier passwd. la valeur par défaut
      est "public_html".
    
      Si vous avez plusieurs hôtes virtuels avec une directive
      UserDir différente
      pour chacun d'entre eux, vous devrez faire en sorte que chaque
      UserDir possède un répertoire parent commun ; donnez alors à
      l'option --with-suexec-userdir le nom
      de ce répertoire commun. Si tout ceci n'est pas défini
      correctement, les requêtes CGI "~userdir" ne fonctionneront
      pas !
    

      
    --with-suexec-docroot=DIR
    

      
    Cette option fonctionne comme la directive DocumentRoot pour
      httpd. Il s'agit de la seule hiérarchie (en dehors des directives
      UserDir) dans laquelle la fonctionnalité suEXEC
      pourra être utilisée. La valeur par défaut est la valeur de
      --datadir accompagnée du suffixe
      "/htdocs" ;
      Par exemple, si vous exécutez configure avec
      "--datadir=/home/apache", la valeur
      "/home/apache/htdocs" sera utilisée par défaut comme
      racine des documents pour le conteneur suEXEC.
    

      
    --with-suexec-uidmin=UID
    

      
    Cette option définit l'identifiant utilisateur le plus bas
      avec lequel un utilisateur pourra être la cible de
      suEXEC. 500 ou 100 sont des valeurs courantes sur la plupart des
      systèmes. la valeur par défaut est 100.
    

      
    --with-suexec-gidmin=GID
    

      
    Cette option définit l'identifiant de groupe le plus bas
      avec lequel un utilisateur pourra être la cible de
      suEXEC. 100 est une valeur courante sur la plupart des
      systèmes et est par conséquent la valeur par défaut.
    

      
    --with-suexec-logfile=FILE
    

      
    Cette option permet de définir le fichier dans lequel
      toutes les transactions et erreurs de suEXEC seront journalisées
      (à des fins d'analyse ou de débogage). Par défaut, le fichier
      journal se nomme "suexec_log" et se trouve dans votre
      répertoire standard des fichiers journaux défini par
      --logfiledir
    

      
    --with-suexec-safepath=PATH
    

      
    Cette option permet de définir une variable d'environnement
      PATH sûre à passer aux exécutables CGI. La valeur par défaut
      est "/usr/local/bin:/usr/bin:/bin".
    
    
    

    
    Compilation et installation du conteneur suEXEC
    
      

    
    Si vous avez activé la fonctionnalité suEXEC à l'aide de
     l'option --enable-suexec, le binaire
     suexec sera automatiquement construit (en même temps
     que httpd) lorsque vous exécuterez la commande
     make.
    

     
    Lorsque tous les composants auront été construits, vous pourrez
     exécuter la commande make install afin de les
     installer. Le binaire suexec sera installé dans le
     répertoire défini à l'aide de l'option --sbindir. La
     localisation par défaut est "/usr/local/apache2/bin/suexec".
    
     
    Veuillez noter que vous aurez besoin des
     privilèges root pour passer l'étape de
     l'installation. Pour que le conteneur puisse changer
     l'identifiant utilisateur, il doit avoir comme propriétaire
     root, et les droits du fichier doivent
     inclure le bit d'exécution setuserid.
    
   

   
    >Mise en place de permissions pour
    paranoïaque
    
	
    
    Bien que le conteneur suEXEC vérifie que l'utilisateur qui
    l'appelle correspond bien à l'utilisateur spécifié à l'aide de
    l'option --with-suexec-caller du programme
    configure, il subsiste toujours le risque qu'un
    appel système ou une bibliothèque fasse appel à suEXEC avant que
    cette vérification ne soit exploitable sur votre système. Pour
    tenir compte de ceci, et parce que c'est en général la meilleure
    pratique, vous devez utiliser les permissions du système de
    fichiers afin de vous assurer que seul le groupe sous lequel
    s'exécute httpd puisse faire appel à suEXEC.
    

    
    Si, par exemple, votre serveur web est configuré pour
    s'exécuter en tant que :
    


    User www
Group webgroup
    


    
    et suexec se trouve à
    "/usr/local/apache2/bin/suexec", vous devez exécuter les
    commandes
    


    
    chgrp webgroup /usr/local/apache2/bin/suexec
    
    chmod 4750 /usr/local/apache2/bin/suexec
    

    

    
    Ceci permet de s'assurer que seul le groupe sous lequel httpd
    s'exécute (ici webgroup) puisse faire appel au conteneur
    suEXEC.
    
  

    top
    

    

    Activation et désactivation
de suEXEC
    

    
    Au démarrage, httpd vérifie la présence du fichier
    suexec dans le répertoire défini par
    l'option --sbindir du script configure (le
    répertoire par défaut est "/usr/local/apache/sbin/suexec"). Si
    httpd trouve un conteneur suEXEC correctement configuré, il
    enregistrera le message suivant dans le journal des erreurs :
    


    
    [notice] suEXEC mechanism enabled (wrapper: /path/to/suexec)

    

    
    Si ce message n'est pas généré au démarrage du serveur, ce
    dernier ne trouve probablement pas le programme conteneur à
    l'endroit où il est sensé être, ou l'exécutable suexec n'est pas
    installé en setuid root.
    

     
    Si le serveur HTTP Apache est déjà en cours d'exécution, et si
     vous activez le mécanisme suEXEC pour la première fois, vous
     devez arrêter et redémarrer httpd. Un redémarrage
     à l'aide d'un simple signal HUP ou USR1 suffira. 
    
     
    Pour désactiver suEXEC, vous devez supprimer le fichier
     suexec, puis arrêter et redémarrer
     httpd.
    

    top
    

    

    Utilisation de suEXEC
    

    
    Les requêtes pour des programmes CGI ne feront appel au
    conteneur suEXEC que si elles concernent un hôte virtuel
    contenant une directive SuexecUserGroup, ou si elles sont
    traitées par mod_userdir.
    

    
    Hôtes virtuels :
     Une des méthodes
    d'utilisation du conteneur suEXEC consiste à insérer une
    directive SuexecUserGroup dans une section
    VirtualHost. En définissant
    des valeurs différentes de celles du serveur principal, toutes les
    requêtes pour des ressources CGI seront exécutées sous
    les User et Group définis pour cette section
    <VirtualHost>. Si cette
    directive est absente de la section <VirtualHost>, l'utilisateur du
    serveur principal sera pris par défaut
    

    
    Répertoires des utilisateurs :
     Avec
    cette méthode, les
    requêtes traitées par mod_userdir appelleront le
    conteneur suEXEC pour exécuter le programme CGI sous l'identifiant
    utilisateur du répertoire utilisateur concerné. Seuls prérequis
    pour pouvoir accéder à cette fonctionnalité : l'exécution des CGI
    doit être activée pour l'utilisateur concerné, et le script doit
    passer avec succès le test des vérifications de
    sécurité décrit plus haut. Voir aussi l'
    option de compilation
    --with-suexec-userdir.
     
    top
    

    

    Débogage de suEXEC
    

    
    Le conteneur suEXEC va écrire ses informations de journalisation
    dans le fichier défini par l'option de compilation
    --with-suexec-logfile comme indiqué plus haut. Si vous
    pensez avoir configuré et installé correctement le conteneur,
    consultez ce journal, ainsi que le journal des erreurs du serveur
    afin de déterminer l'endroit où vous avez fait fausse route.

    serveur. Veuillez en prendre connaissance avant de soumettre un
    rapport de bogue à propos de suEXEC.
    

    
    Points importants à propos de suEXEC
    
    
      
 
      
    • 
        Limitations concernant la hiérarchie.

        
      
          Pour des raisons de sécurité et d'efficacité, toutes les
	  requêtes suEXEC ne doivent concerner que des ressources
	  situées dans la racine des documents définie pour les
	  requêtes concernant un hôte virtuel, ou des ressources
	  situées dans la racine des documents définies pour les
	  requêtes concernant un répertoire utilisateur. Par exemple,
	  si vous avez configuré quatre hôtes virtuels, vous devrez
	  définir la structure des racines de documents de vos hôtes
	  virtuels en dehors d'une hiérarchie de documents principale
	  de httpd, afin de tirer parti de suEXEC dans le contexte des
	  hôtes virtuels (Exemple à venir).
        
      
      
      • 

      
    • 
        La variable d'environnement PATH de suEXEC

        
      
          Modifier cette variable peut s'avérer dangereux. Assurez-vous
	  que tout chemin que vous ajoutez à cette variable est un
	  répertoire de confiance. Vous n'avez
	  probablement pas l'intention d'ouvrir votre serveur de façon
	  à ce que l'on puisse y exécuter un cheval de Troie.
        
      
      
      • 

      
    • 
        Modification de suEXEC

        
      
          Encore une fois, ceci peut vous causer de
	  graves ennuis si vous vous y essayez sans
	  savoir ce que vous faites. Evitez de vous y risquer dans la
	  mesure du possible.

        kendisinde tasarlanmış yanıtlayıcının tercih edilip edilmeyeceği
        kararına bağlı olarak yapılandırılabilir.
    

      
    mod_ssl, ayrıca, sunucunun istemciyle anlaşma
        sırasında kendi sertifikasının OCSP doğrulamasını umursamazca sağlayıp
        aktardığı durumda OCSP zımbalamasını da destekler.
    

      
    mod_ssl, sunucular arasında SSL Oturumu verisini
        memcached üzerinden paylaşmak üzere yapılandırılabilir.

    ProxyPass yönergesi bir
        Location veya
        LocationMatch bloku içinde en
        verimli şekilde yapılandırılabilir ve büyük sayıların varlığı durumunda
        geleneksel iki değiştirgeli sözdiziminin de üzerinde belirgin bir
        başarım artışı sağlar.
    

      
    Vekil istekleri için kullanılan kaynak adresi artık
        yapılandırılabilmektedir.
    

      
    Artalanda Unix alan soketleri için destek (2.4.7 itibariyle
        kullanılabilir).
    

      
    mod_proxy_balancer
    

      
    Dengeleme yöneticisi üzerinden BalancerMembers için daha fazla
        çalışma anı yapılandırması
    

      
    Çalışma anında dengeleme yöneticisi üzerinden başka BalancerMembers
        eklenebilir.
    

      
    Çalışma anı yapılandırmasına yönelik dengeleyici değiştirgeleri
    

      
    BalancerMembers için 'Drain' değeri belirtilebilir; böylece sadece
        mevcut yapışık oturumlara yanıt verirler ve bunların güzellikle hattan
        alınması mümkün olur.
    

      
    Balancer ayarları sunucu yeniden başlatılssa bile kalıcı olabilir.
        
    

      
    mod_cache
    

      
    mod_cache CACHE süzgeci, arabellekleme üzerinde daha
        hassas denetim sağlamak için istenirse süzgeç zincirinin belli bir
        noktasına yerleştirilebilmektedir.
    

      
    mod_cache artık HEAD isteklerini
        arabellekleyebiliyor.
    

      
    Mümkün olduğunda, mod_cache yönergeleri sunucu
        bazında değil, dizin bazında belirtilebiliyor.
    

      
    Arabellekli URL'lerin temel URL'si özelleştirilebiliyor; böylece
         arabelleğin bir bölümü aynı uç URL önekini paylaşabiliyor.
    

      
    mod_cache, ardalanda bir sağlayıcının olmadığı
        durumda (5xx hatası), arabelleklenmiş bayat içeriği sunabiliyor.
    

      
    mod_cache artık bir X-Cache başlığına bir
        HIT/MISS/REVALIDATE yerleştirebiliyor.

        destek.
    

      
    mod_cgi, mod_include,
          mod_isapi, ...
    
      
    Başlıkların ortam değişkenlerine dönüşümü, başlık zerki yoluyla bazı
        olası karşı-site-betik saldırılarının hafifletilmesinden önce daha
        hızlı ve doğru yapılmaktadır. Geçersiz karakterler (altçizgiler dahil)
        içeren başlık isimleri artık sessizce bırakılmaktadır.Apache'deki Ortam değişkenleri, böyle başlıkları
        gerektiren bozulmuş meşru istemcilerin çevresinden dolanabilen
        göstericilere sahiptir. (Bu durum, bu değişkenleri kullanan tüm
        modülleri etkiler.)
    

      
    mod_authz_core Yetkilendirme Kuralları
        Taşıyıcıları
    

      
    Gelişkin yetkilendirme kuralları artık Require yönergesi ve <RequireAll> gibi
        ilgili taşıyıcı yönergeler kullanılarak belirtilebilmektedir.
    

      
    mod_rewrite
    
      
    mod_rewrite bildik yeniden yazma senaryolarını
        basitleştirmek için RewriteRule yönergesine
        [QSD] (Query String Discard=sorgu dizgisini iptal) ve
        [END] seçeneklerini sağlamaktadır.
    
      
    RewriteCond içinde
        karmaşık mantıksal ifadeler kullanımını mümkün kılmaktadır.

    mod_ldap zaman aşımlarını işleme sokabilmek için
          LDAPConnectionPoolTTL,
          LDAPTimeout ve birtakım
          başka geliştirmeler sahiptir. Özellikle, bir LDAP sunucusunun boşta
          kalmış bağlantılarını bıraktıran bir durumsal güvenlik duvarı
          varlığında gerekli ayarlamaları yapmak için kullanışlıdır.
    
      
    mod_ldap, artık, LDAP araç kiti kullanarak sağlanan
        hata ayıklama bilgisini günlüklemek için LDAPLibraryDebug yönergesini
        içermektedir.
    

      
    mod_info
    
      
    mod_info önceden çözümlenmiş yapılandırmayı artık
        sunucunun başlatılması sırasında standart çıktıya
        dökümleyebilmektedir.
    

      
    mod_auth_basic

    Dosya boyutları belirtilen blok boyutuna yukarı doğru
          yuvarlanabilmekte, böylece dosya boyutu sınırları diskteki gerçek
          boyutlarla daha iyi eşlenebilmektedir.
    
        
    Arabellek boyutu artık, diskteki dosyaların boyutuna göre bir
          sınıra ek olarak veya bunun yerine dosya düğümü sayısı ile
          sınırlanabilmektedir.
    

        
    rotatelogs
    
        
    Artık geçerli günlük dosyasına bir bağ oluşturulabiliyor.
    
        
    Artık özel bir döndürme sonrası betiği çalıştırılabiliyor.
    

      
    htpasswd, htdbm
    
      
    Bcrypt algoritması için destek (2.4.4 itibariyle
        kullanılabilmektedir).

    Belgelendirme
    
    
    
    
        
    mod_rewrite
    
        
    mod_rewrite belgeleri, yeniden düzenlenerek,
          genel kullanıma ve örneklere odaklı olarak ve diğer çözümlerin hangi
          durumlarda daha uygun olduğu da gösterilerek hemen hemen tamamen
          yeniden yazıldı. Yeniden Yazma Kılavuzu artık
          bir sayfa olmaktan çıkıp, çok daha ayrıntılı ve daha iyi düzenlenmiş
          bir bölüm haline geldi.
    

        
    mod_ssl
    
        
    mod_ssl belgeleri, evvelki teknik ayrıntılara ek
          olarak başlarken seviyesinde daha fazla örnekle büyük oranda
          genişletildi.
    

        
    Önbellek Kullanım Kılavuzu
    
        
    Önbellek Kullanım Kılavuzu
          mod_cache tarafından sağlanan RFC2616 HTTP/1.1
          önbellekleme özellikleri arasıda daha iyi ayrım yapılabilmesi için ve
          socache arayüzü ile sağlanan soysal
          anahtar/değer önbelleklemesi yanında mod_file_cache
          gibi mekanizmalarla sağlanan özelleştirilebilir arabelleklemeyi de
          kapsamak üzere yeniden yazıldı.

    Modül Geliştirici Değişiklikleri
    
    
    
    
      
    Yapılandırma Denetleme Kancası Eklendi
    

      
    Yeni bir kanca, check_config kancası,
        pre_config ve open_logs kancaları arasında
        çalışmak üzere eklendi. Ayrıca, httpd'ye
        -t seçeneği verildiğinde test_config
        kancasından önce çalışır. check_config kancası, modüllerin
        karşılıklı bağımlı yapılandırma yönergesi değerlerini yeniden
        yoklamasını ve iletiler konsola hala günlüklenebiliyorken bunların
        ayarlanabilmesini sağlar. Temel open_logs kanca işlevi
        konsol çıktısını hata günlüğüne yönlendirmeden önce hatalı yapılandırma
        sorunlarına karşı kullanıcı uyarılabilir.
    

      
    İfade Çözümleyici Eklendi
    

      
    Artık genel amaçlı bir ifade çözümleyicimiz var. API
        ap_expr.h içinde incelenebilir. Evvelce
        mod_ssl içinde gerçeklenmiş olan ifade çözümleyiciden
        esinlenildi.
    

      
    Yetkilendirme Kuralları Taşıyıcıları
    

      
    Yetkilendirme modülleri, <RequireAll> gibi gelişmiş yetkilendirme
        kuralı taşıyıcılarını desteklemek için ap_register_auth_provider()
        üzerinden artık bir sağlayıcı olarak çalıştırılabilmektedir.
    

      
    Küçük Nesne Arabellekleme Arayüzü
    

      
    ap_socache.h, evvelki mod_ssl oturum
        arabelleği gerçeklenimine dayalı olarak küçük veri nesnelerini
        arabelleklemek için sağlayıcı temelli bir arayüz ortaya koyar.
        Paylaşımlı bellek çevrimsel tamponu kullanan sağlayıcılar, disk bazlı
        dbm dosyaları ve memcache ile dağıtılan arabellekler şu an
        desteklenmektedir.
    

      
    Arabellek Durum Kancası Eklendi
    

      
    mod_cache modülü artık, arabellekleme kararı bilinir
        olduğunda çağrılan yeni bir cache_status kancası içeriyor.
        Öntanımlı gerçeklenim, yanıta istemlik bir X-Cache ve
        X-Cache-Detail ekleyebilmektedir.
    
    
    

    
    Geliştirici belgeleri API
      değişikliklerinin ayrıntılı bir listesini içermektedir.

    介绍
    

    
    Apache HTTP 服务器被设计为一个功能强大，并且灵活的 web 服务器，
    可以在很多平台与环境中工作。不同平台和不同的环境往往需要不同
    的特性，或可能以不同的方式实现相同的特性最有效率。Apache httpd
    通过模块化的设计来适应各种环境。这种设计允许网站管理员通过在
    编译时或运行时，选择哪些模块将会加载在服务器中，来选择服务器特性。
    

    
    Apache HTTP 服务器 2.0 扩展此模块化设计到最基本的 web 服务器功能。
    它提供了可以选择的多处理模块(MPM)，用来绑定到网络端口上，接受请求，
    以及调度子进程处理请求。
    

    
    扩展到这一级别的服务器模块化设计，带来两个重要的好处:
    

    
      
      
    • Apache httpd 能更优雅，更高效率的支持不同的平台。尤其是
      Apache httpd 的 Windows 版本现在更有效率了，因为
      mpm_winnt 能使用原生网络特性取代在
      Apache httpd 1.3 中使用的 POSIX 层。它也可以扩展到其它平台
      来使用专用的 MPM。
      • 

      
    • Apache httpd 能更好的为有特殊要求的站点定制。例如，要求
      更高伸缩性的站点可以选择使用线程的 MPM，即
      worker 或 event；
      需要可靠性或者与旧软件兼容的站点可以使用
      prefork。
      • 
    
    

    
    在用户看来，MPM 很像其它 Apache httpd 模块。主要是区别是，在任何时间，
    必须有一个，而且只有一个 MPM 加载到服务器中。可用的 MPM 列表位于
    模块索引页面。
    


    top
    

    

    默认 MPM
    


    下表列出了不同系统的默认 MPM。如果你不在编译时选择，那么它就是你将要使用的 MPM。

    Unixprefork，worker 或
    event，取决于平台特性
    

    Windowsmpm_winnt
    

    

    top
    

    

    构建 MPM 为静态模块
    

    
    在全部平台中，MPM 都可以构建为静态模块。在构建时选择一种
    MPM，链接到服务器中。如果要改变 MPM，必须重新构建。
    

    
    为了使用指定的 MPM，请在执行 configure 脚本
      时，使用参数 --with-mpm=NAME。NAME
      是指定的 MPM 名称。
    

    
    编译完成后，可以使用 ./httpd -l 来确定选择的 MPM。
    此命令会列出编译到服务器程序中的所有模块，包括 MPM。
    


    top
    

    

    构建 MPM 为动态模块
    

    
    在 Unix 或类似平台中，MPM 可以构建为动态模块，与其它动态模块一样在运行时加载。
    构建 MPM 为动态模块允许通过修改 LoadModule
    指令内容来改变 MPM，而不用重新构建服务器程序。
    

    
    在执行 configure 脚本时，使用
    --enable-mpms-shared 选项可以启用此特性。
    当给出的参数为 all 时，所有此平台支持的 MPM
    模块都会被安装。还可以在参数中给出模块列表。
    

    
    默认 MPM，可以自动选择或者在执行 configure
    脚本时通过 --with-mpm 选项来指定，然后出现在生成的服务器配置文件中。
    编辑 LoadModule 指令内容可以选择不同的 MPM。

    This document supplements the mod_cache,
    mod_cache_disk, mod_file_cache and htcacheclean reference documentation.
    It describes how to use the Apache HTTP Server's caching features to accelerate web and
    proxy serving, while avoiding common problems and misconfigurations.
    
  
    


    top
    

    

    Introduction
    
    
    
    
    The Apache HTTP server offers a range of caching features that
    are designed to improve the performance of the server in various
    ways.
    

    
    
        
    Three-state RFC2616 HTTP caching
    
        
    
            mod_cache
            and its provider modules
            mod_cache_disk
            provide intelligent, HTTP-aware caching. The content itself is stored
            in the cache, and mod_cache aims to honor all of the various HTTP
            headers and options that control the cacheability of content
            as described in
            Section
            13 of RFC2616.
            mod_cache
            is aimed at both simple and complex caching configurations, where
            you are dealing with proxied content, dynamic local content or
            have a need to speed up access to local files on a potentially
            slow disk.
        
    

        
    Two-state key/value shared object caching
    
        
    
            The shared object cache API (socache)
            and its provider modules provide a
            server wide key/value based shared object cache. These modules
            are designed to cache low level data such as SSL sessions and
            authentication credentials. Backends allow the data to be stored
            server wide in shared memory, or datacenter wide in a cache such
            as memcache or distcache.
        
    

        
    Specialized file caching
    
        
    
            mod_file_cache
            offers the ability to pre-load
            files into memory on server startup, and can improve access
            times and save file handles on files that are accessed often,
            as there is no need to go to disk on each request.
        
    
    
    

    
    To get the most from this document, you should be familiar with
    the basics of HTTP, and have read the Users' Guides to
    Mapping URLs to the Filesystem and
    Content negotiation.

    Three-state RFC2616 HTTP caching
    

    

    
    Related ModulesRelated Directives
    

    
    The HTTP protocol contains built in support for an in-line caching
    mechanism 
    
    described by section 13 of RFC2616, and the
    mod_cache module can be used to take advantage of
    this.
    

    
    Unlike a simple two state key/value cache where the content
    disappears completely when no longer fresh, an HTTP cache includes
    a mechanism to retain stale content, and to ask the origin server
    whether this stale content has changed and if not, make it fresh
    again.
    

    
    An entry in an HTTP cache exists in one of three states:
    

    
    
    
    Fresh
    
    
    
        If the content is new enough (younger than its freshness
        lifetime), it is considered fresh. An
        HTTP cache is free to serve fresh content without making any
        calls to the origin server at all.
    
    
    
    Stale
    
    
    
        
    If the content is too old (older than its freshness
        lifetime), it is considered stale. An
        HTTP cache should contact the origin server and check whether
        the content is still fresh before serving stale content to a
        client. The origin server will either respond with replacement
        content if not still valid, or ideally, the origin server will
        respond with a code to tell the cache the content is still
        fresh, without the need to generate or send the content again.
        The content becomes fresh again and the cycle continues.
    

        
    The HTTP protocol does allow the cache to serve stale data
        under certain circumstances, such as when an attempt to freshen
        the data with an origin server has failed with a 5xx error, or
        when another request is already in the process of freshening
        the given entry. In these cases a Warning header
        is added to the response.
    
    
    
    
    Non Existent
    
    
    
        If the cache gets full, it reserves the option to delete content
        from the cache to make space. Content can be deleted at any time,
        and can be stale or fresh. The htcacheclean tool can be
        run on a once off basis, or deployed as a daemon to keep the size
        of the cache within the given size, or the given number of inodes.
        The tool attempts to delete stale content before attempting to
        delete fresh content.
    
    
    
    

    
    Full details of how HTTP caching works can be found in
    
    Section 13 of RFC2616.
    

    
    Interaction with the Server
    
      

      
    The mod_cache module hooks into the server in two
      possible places depending on the value of the
      CacheQuickHandler directive:
      
    

      
    
        
    Quick handler phase
    
        
    
          
    This phase happens very early on during the request processing,
              just after the request has been parsed. If the content is
              found within the cache, it is served immediately and almost
              all request processing is bypassed.
    

              
    In this scenario, the cache behaves as if it has been "bolted
              on" to the front of the server.
    
              
              
    This mode offers the best performance, as the majority of
              server processing is bypassed. This mode however also bypasses the
              authentication and authorization phases of server processing, so
              this mode should be chosen with care when this is important.
    
  
              
     Requests with an "Authorization" header (for example, HTTP Basic
              Authentication) are neither cacheable nor served from the cache 
              when mod_cache is running in this phase.
    
          
    
          
    Normal handler phase
    
          
    
              
    This phase happens late in the request processing, after all
              the request phases have completed.
    

              
    In this scenario, the cache behaves as if it has been "bolted
              on" to the back of the server.
    

              
    This mode offers the most flexibility, as the potential exists
              for caching to occur at a precisely controlled point in the filter
              chain, and cached content can be filtered or personalized before
              being sent to the client.
    
          
    
        
    

        
    If the URL is not found within the cache, mod_cache
        will add a filter to the filter stack in order
        to record the response to the cache, and then stand down, allowing normal
        request processing to continue. If the content is determined to be
        cacheable, the content will be saved to the cache for future serving,
        otherwise the content will be ignored.
    

        
    If the content found within the cache is stale, the
        mod_cache module converts the request into a
        conditional request. If the origin server responds with
        a normal response, the normal response is cached, replacing the content
        already cached. If the origin server responds with a 304 Not Modified
        response, the content is marked as fresh again, and the cached content
        is served by the filter instead of saving it.
    
    

    
    Improving Cache Hits
    
      

      
    When a virtual host is known by one of many different server aliases,
      ensuring that UseCanonicalName is
      set to On can dramatically improve the ratio of cache hits.
      This is because the hostname of the virtual-host serving the content is
      used within the cache key. With the setting set to On
      virtual-hosts with multiple server names or aliases will not produce
      differently cached entities, and instead content will be cached as
      per the canonical hostname.
    

    

    
    Freshness Lifetime
    
      

      
    Well formed content that is intended to be cached should declare an
      explicit freshness lifetime with the Cache-Control
      header's max-age or s-maxage fields, or
      by including an Expires header.
    
      
      
    At the same time, the origin server defined freshness lifetime can
      be overridden by a client when the client presents their own
      Cache-Control header within the request. In this case,
      the lowest freshness lifetime between request and response wins.
    

      
    When this freshness lifetime is missing from the request or the
      response, a default freshness lifetime is applied. The default
      freshness lifetime for cached entities is one hour, however
      this can be easily over-ridden by using the CacheDefaultExpire directive.
    

      
    If a response does not include an Expires header but does
      include a Last-Modified header, mod_cache
      can infer a freshness lifetime based on a heuristic, which can be
      controlled through the use of the CacheLastModifiedFactor directive.
    

      
    For local content, or for remote content that does not define its own
      Expires header, mod_expires may be used to
      fine-tune the freshness lifetime by adding max-age and
      Expires.
    

      
    The maximum freshness lifetime may also be controlled by using the
      CacheMaxExpire.
    

    

    
    A Brief Guide to Conditional Requests
    
      

      
    When content expires from the cache and becomes stale, rather than
      pass on the original request, httpd will modify the request to make
      it conditional instead.
    

      
    When an ETag header exists in the original cached
      response, mod_cache will add an
      If-None-Match header to the request to the origin server.
      When a Last-Modified header exists in the original
      cached response, mod_cache will add an
      If-Modified-Since header to the request to the origin
      server. Performing either of these actions makes the request
      conditional.
    

      
    When a conditional request is received by an origin server, the
      origin server should check whether the ETag or the Last-Modified
      parameter has changed, as appropriate for the request. If not, the
      origin should respond with a terse "304 Not Modified" response. This
      signals to the cache that the stale content is still fresh should be
      used for subsequent requests until the content's new freshness lifetime
      is reached again.
    

      
    If the content has changed, then the content is served as if the
      request were not conditional to begin with.
    

      
    Conditional requests offer two benefits. Firstly, when making such
      a request to the origin server, if the content from the origin
      matches the content in the cache, this can be determined easily and
      without the overhead of transferring the entire resource.
    

      
    Secondly, a well designed origin server will be designed in such
      a way that conditional requests will be significantly cheaper to
      produce than a full response. For static files, typically all that is
      involved is a call to stat() or similar system call, to
      see if the file has changed in size or modification time. As such, even
      local content may still be served faster from the cache if it has not
      changed.
    
      
      
    Origin servers should make every effort to support conditional
      requests as is practical, however if conditional requests are not
      supported, the origin will respond as if the request was not
      conditional, and the cache will respond as if the content had changed
      and save the new content to the cache. In this case, the cache will
      behave like a simple two state cache, where content is effectively
      either fresh or deleted.
    
    

    
    What Can be Cached?
    
      

      
    The full definition of which responses can be cached by an HTTP
      cache is defined in
      
      RFC2616 Section 13.4 Response Cacheability, and can be summed up as
      follows:
    

      
      
        
    1. Caching must be enabled for this URL. See the CacheEnable and CacheDisable directives.
      2. 

        
    2. If the response has an HTTP status code other than 200, 203, 300, 
        301 or 410 it must also specify an "Expires" or "Cache-Control" header.
        
      3. 

        
    3. The request must be a HTTP GET request.
      4. 

        
    4. If the response contains an "Authorization:" header, it must
        also contain an "s-maxage", "must-revalidate" or "public" option
        in the "Cache-Control:" header, or it won't be cached.
      5. 

        
    5. If the URL included a query string (e.g. from a HTML form GET
        method) it will not be cached unless the response specifies an
        explicit expiration by including an "Expires:" header or the max-age
        or s-maxage directive of the "Cache-Control:" header, as per RFC2616
        sections 13.9 and 13.2.1.
      6. 

        
    6. If the response has a status of 200 (OK), the response must
        also include at least one of the "Etag", "Last-Modified" or
        the "Expires" headers, or the max-age or s-maxage directive of
        the "Cache-Control:" header, unless the
        CacheIgnoreNoLastMod
        directive has been used to require otherwise.
      7. 

        
    7. If the response includes the "private" option in a "Cache-Control:"
        header, it will not be stored unless the
        CacheStorePrivate has been
        used to require otherwise.
      8. 

        
    8. Likewise, if the response includes the "no-store" option in a
        "Cache-Control:" header, it will not be stored unless the
        CacheStoreNoStore has been
        used.
      9. 

        
    9. A response will not be stored if it includes a "Vary:" header
        containing the match-all "*".
      10. 
      
    
    

    
    What Should Not be Cached?
    
      

      
    It should be up to the client creating the request, or the origin
      server constructing the response to decide whether or not the content
      should be cacheable or not by correctly setting the
      Cache-Control header, and mod_cache should
      be left alone to honor the wishes of the client or server as appropriate.
      
    

      
    Content that is time sensitive, or which varies depending on the
      particulars of the request that are not covered by HTTP negotiation,
      should not be cached. This content should declare itself uncacheable
      using the Cache-Control header.
    
      
      
    If content changes often, expressed by a freshness lifetime of minutes
      or seconds, the content can still be cached, however it is highly
      desirable that the origin server supports
      conditional requests correctly to ensure that
      full responses do not have to be generated on a regular basis.
    

      
    Content that varies based on client provided request headers can be
      cached through intelligent use of the Vary response
      header.
    

    

    
    Variable/Negotiated Content
    
      

      
    When the origin server is designed to respond with different content
      based on the value of headers in the request, for example to serve
      multiple languages at the same URL, HTTP's caching mechanism makes it
      possible to cache multiple variants of the same page at the same URL.
    
      
      
    This is done by the origin server adding a Vary header
      to indicate which headers must be taken into account by a cache when
      determining whether two variants are different from one another.
    

      
    If for example, a response is received with a vary header such as;
    

      
    
Vary: negotiate,accept-language,accept-charset
      
    

      
    mod_cache will only serve the cached content to
      requesters with accept-language and accept-charset headers
      matching those of the original request.
    
      
      
    Multiple variants of the content can be cached side by side,
      mod_cache uses the Vary header and the
      corresponding values of the request headers listed by Vary
      to decide on which of many variants to return to the client.

    Cache Setup Examples
    

    

    
    Related ModulesRelated Directives
    

    
    Caching to Disk
    
      

      
    The mod_cache module relies on specific backend store
      implementations in order to manage the cache, and for caching to disk
      mod_cache_disk is provided to support this.
    

      
    Typically the module will be configured as so;
    

      
    CacheRoot   "/var/cache/apache/"
CacheEnable disk /
CacheDirLevels 2
CacheDirLength 1
    


      
    Importantly, as the cached files are locally stored, operating system
      in-memory caching will typically be applied to their access also. So
      although the files are stored on disk, if they are frequently accessed
      it is likely the operating system will ensure that they are actually
      served from memory.
    

    

    
    Understanding the Cache-Store
    
      

      
    To store items in the cache, mod_cache_disk creates
      a 22 character hash of the URL being requested. This hash incorporates
      the hostname, protocol, port, path and any CGI arguments to the URL,
      as well as elements defined by the Vary header to ensure that multiple
      URLs do not collide with one another.
    

      
    Each character may be any one of 64-different characters, which mean
      that overall there are 64^22 possible hashes. For example, a URL might
      be hashed to xyTGxSMO2b68mBCykqkp1w. This hash is used
      as a prefix for the naming of the files specific to that URL within
      the cache, however first it is split up into directories as per
      the CacheDirLevels and
      CacheDirLength
      directives.
    

      
    CacheDirLevels
      specifies how many levels of subdirectory there should be, and
      CacheDirLength
      specifies how many characters should be in each directory. With
      the example settings given above, the hash would be turned into
      a filename prefix as
      /var/cache/apache/x/y/TGxSMO2b68mBCykqkp1w.
    

      
    The overall aim of this technique is to reduce the number of
      subdirectories or files that may be in a particular directory,
      as most file-systems slow down as this number increases. With
      setting of "1" for
      CacheDirLength
      there can at most be 64 subdirectories at any particular level.
      With a setting of 2 there can be 64 * 64 subdirectories, and so on.
      Unless you have a good reason not to, using a setting of "1"
      for CacheDirLength
      is recommended.
    

      
    Setting
      CacheDirLevels
      depends on how many files you anticipate to store in the cache.
      With the setting of "2" used in the above example, a grand
      total of 4096 subdirectories can ultimately be created. With
      1 million files cached, this works out at roughly 245 cached
      URLs per directory.
    

      
    Each URL uses at least two files in the cache-store. Typically
      there is a ".header" file, which includes meta-information about
      the URL, such as when it is due to expire and a ".data" file
      which is a verbatim copy of the content to be served.
    

      
    In the case of a content negotiated via the "Vary" header, a
      ".vary" directory will be created for the URL in question. This
      directory will have multiple ".data" files corresponding to the
      differently negotiated content.
    
    

    
    Maintaining the Disk Cache
    
      

      
    The mod_cache_disk module makes no attempt to
      regulate the amount of disk space used by the cache, although it
      will gracefully stand down on any disk error and behave as if the
      cache was never present.
    

      
    Instead, provided with httpd is the htcacheclean tool which allows you
      to clean the cache periodically. Determining how frequently to run htcacheclean and what target size to
      use for the cache is somewhat complex and trial and error may be needed to
      select optimal values.
    

      
    htcacheclean has two modes of
      operation. It can be run as persistent daemon, or periodically from
      cron. htcacheclean can take up to an hour
      or more to process very large (tens of gigabytes) caches and if you are
      running it from cron it is recommended that you determine how long a typical
      run takes, to avoid running more than one instance at a time.
    
 
      
    It is also recommended that an appropriate "nice" level is chosen for
      htcacheclean so that the tool does not cause excessive disk io while the
      server is running.
    

      
    
      
    
      Figure 1: Typical
      cache growth / clean sequence.
    

      
    Because mod_cache_disk does not itself pay attention
      to how much space is used you should ensure that
      htcacheclean is configured to
      leave enough "grow room" following a clean.
    
    

    
    Caching to memcached
    
      

      
    Using the mod_cache_socache module, mod_cache
      can cache data from a variety of implementations (aka: "providers"). Using the
      mod_socache_memcache module, for example, one can specify that
      memcached is to be used as the
      the backend storage mechanism.
    

      
    Typically the module will be configured as so:
    

      
    CacheEnable socache /
CacheSocache memcache:memcd.example.com:11211
    


      
    Additional memcached servers can be specified by
      appending them to the end of the CacheSocache memcache:
      line separated by commas:
    

      
    CacheEnable socache /
CacheSocache memcache:mem1.example.com:11211,mem2.example.com:11212
    


      
    This format is also used with the other various mod_cache_socache
      providers. For example:
    

      
    CacheEnable socache /
CacheSocache shmcb:/path/to/datafile(512000)
    


      
    CacheEnable socache /
CacheSocache dbm:/path/to/datafile

    Specialized File Caching
    

    

    
    Related ModulesRelated Directives
    

    
    On platforms where a filesystem might be slow, or where file
    handles are expensive, the option exists to pre-load files into
    memory on startup.
    

    
    On systems where opening files is slow, the option exists to
    open the file on startup and cache the file handle. These
    options can help on systems where access to static files is
    slow.
    

    
    File-Handle Caching
    
      

      
    The act of opening a file can itself be a source of delay, particularly
      on network filesystems. By maintaining a cache of open file descriptors
      for commonly served files, httpd can avoid this delay. Currently httpd
      provides one implementation of File-Handle Caching.
    

      
    CacheFile
    
        

        
    The most basic form of caching present in httpd is the file-handle
        caching provided by mod_file_cache. Rather than caching
        file-contents, this cache maintains a table of open file descriptors. Files
        to be cached in this manner are specified in the configuration file using
        the CacheFile
        directive.
    

        
    The
        CacheFile directive
        instructs httpd to open the file when it is started and to re-use
        this file-handle for all subsequent access to this file.
    

        
    CacheFile /usr/local/apache2/htdocs/index.html
    


        
    If you intend to cache a large number of files in this manner, you
        must ensure that your operating system's limit for the number of open
        files is set appropriately.
    

        
    Although using CacheFile
        does not cause the file-contents to be cached per-se, it does mean
        that if the file changes while httpd is running these changes will
        not be picked up. The file will be consistently served as it was
        when httpd was started.
    

        
    If the file is removed while httpd is running, it will continue
        to maintain an open file descriptor and serve the file as it was when
        httpd was started. This usually also means that although the file
        will have been deleted, and not show up on the filesystem, extra free
        space will not be recovered until httpd is stopped and the file
        descriptor closed.
    
      

    

    
    In-Memory Caching
    
      

      
    Serving directly from system memory is universally the fastest method
      of serving content. Reading files from a disk controller or, even worse,
      from a remote network is orders of magnitude slower. Disk controllers
      usually involve physical processes, and network access is limited by
      your available bandwidth. Memory access on the other hand can take mere
      nano-seconds.
    

      
    System memory isn't cheap though, byte for byte it's by far the most
      expensive type of storage and it's important to ensure that it is used
      efficiently. By caching files in memory you decrease the amount of
      memory available on the system. As we'll see, in the case of operating
      system caching, this is not so much of an issue, but when using
      httpd's own in-memory caching it is important to make sure that you
      do not allocate too much memory to a cache. Otherwise the system
      will be forced to swap out memory, which will likely degrade
      performance.
    

      
    Operating System Caching
    
        

        
    Almost all modern operating systems cache file-data in memory managed
        directly by the kernel. This is a powerful feature, and for the most
        part operating systems get it right. For example, on Linux, let's look at
        the difference in the time it takes to read a file for the first time
        and the second time;
    

        
    colm@coroebus:~$ time cat testfile > /dev/null
real    0m0.065s
user    0m0.000s
sys     0m0.001s
colm@coroebus:~$ time cat testfile > /dev/null
real    0m0.003s
user    0m0.003s
sys     0m0.000s
    

        
    Even for this small file, there is a huge difference in the amount
        of time it takes to read the file. This is because the kernel has cached
        the file contents in memory.
    

        
    By ensuring there is "spare" memory on your system, you can ensure
        that more and more file-contents will be stored in this cache. This
        can be a very efficient means of in-memory caching, and involves no
        extra configuration of httpd at all.
    

        
    Additionally, because the operating system knows when files are
        deleted or modified, it can automatically remove file contents from the
        cache when necessary. This is a big advantage over httpd's in-memory
        caching which has no way of knowing when a file has changed.
    
      

      
    Despite the performance and advantages of automatic operating system
      caching there are some circumstances in which in-memory caching may be
      better performed by httpd.
    

      
    MMapFile Caching
    
        

        
    mod_file_cache provides the
        MMapFile directive, which
        allows you to have httpd map a static file's contents into memory at
        start time (using the mmap system call). httpd will use the in-memory
        contents for all subsequent accesses to this file.
    

        
    MMapFile /usr/local/apache2/htdocs/index.html
    


        
    As with the
        CacheFile directive, any
        changes in these files will not be picked up by httpd after it has
        started.
    

        
     The MMapFile
        directive does not keep track of how much memory it allocates, so
        you must ensure not to over-use the directive. Each httpd child
        process will replicate this memory, so it is critically important
        to ensure that the files mapped are not so large as to cause the
        system to swap memory.

    Security Considerations
    
    

    
    Authorization and Access Control
    
      

      
    Using mod_cache in its default state where
      CacheQuickHandler is set to
      On is very much like having a caching reverse-proxy bolted
      to the front of the server. Requests will be served by the caching module
      unless it determines that the origin server should be queried just as an
      external cache would, and this drastically changes the security model of
      httpd.
    

      
    As traversing a filesystem hierarchy to examine potential
      .htaccess files would be a very expensive operation,
      partially defeating the point of caching (to speed up requests),
      mod_cache makes no decision about whether a cached
      entity is authorised for serving. In other words; if
      mod_cache has cached some content, it will be served
      from the cache as long as that content has not expired.
    

      
    If, for example, your configuration permits access to a resource by IP
      address you should ensure that this content is not cached. You can do this
      by using the CacheDisable
      directive, or mod_expires. Left unchecked,
      mod_cache - very much like a reverse proxy - would cache
      the content when served and then serve it to any client, on any IP
      address.
    

      
    When the CacheQuickHandler
      directive is set to Off, the full set of request processing
      phases are executed and the security model remains unchanged.
    
    

    
    Local exploits
    
      

      
    As requests to end-users can be served from the cache, the cache
      itself can become a target for those wishing to deface or interfere with
      content. It is important to bear in mind that the cache must at all
      times be writable by the user which httpd is running as. This is in
      stark contrast to the usually recommended situation of maintaining
      all content unwritable by the Apache user.
    

      
    If the Apache user is compromised, for example through a flaw in
      a CGI process, it is possible that the cache may be targeted. When
      using mod_cache_disk, it is relatively easy to
      insert or modify a cached entity.
    

      
    This presents a somewhat elevated risk in comparison to the other
      types of attack it is possible to make as the Apache user. If you are
      using mod_cache_disk you should bear this in mind -
      ensure you upgrade httpd when security upgrades are announced and
      run CGI processes as a non-Apache user using suEXEC if possible.
    

    

    
    Cache Poisoning
    
      

      
    When running httpd as a caching proxy server, there is also the
      potential for so-called cache poisoning. Cache Poisoning is a broad
      term for attacks in which an attacker causes the proxy server to
      retrieve incorrect (and usually undesirable) content from the origin
      server.
    

      
    For example if the DNS servers used by your system running httpd
      are vulnerable to DNS cache poisoning, an attacker may be able to control
      where httpd connects to when requesting content from the origin server.
      Another example is so-called HTTP request-smuggling attacks.
    

      
    This document is not the correct place for an in-depth discussion
      of HTTP request smuggling (instead, try your favourite search engine)
      however it is important to be aware that it is possible to make
      a series of requests, and to exploit a vulnerability on an origin
      webserver such that the attacker can entirely control the content
      retrieved by the proxy.
    
    

    
    Denial of Service / Cachebusting
    
      

      
    The Vary mechanism allows multiple variants of the same URL to be
      cached side by side. Depending on header values provided by the client,
      the cache will select the correct variant to return to the client. This
      mechanism can become a problem when an attempt is made to vary on a
      header that is known to contain a wide range of possible values under
      normal use, for example the User-Agent header. Depending
      on the popularity of the particular web site thousands or millions of
      duplicate cache entries could be created for the same URL, crowding
      out other entries in the cache.
    
      
      
    In other cases, there may be a need to change the URL of a particular
      resource on every request, usually by adding a "cachebuster" string to
      the URL. If this content is declared cacheable by a server for a
      significant freshness lifetime, these entries can crowd out
      legitimate entries in a cache. While mod_cache
      provides a
      CacheIgnoreURLSessionIdentifiers
      directive, this directive should be used with care to ensure that
      downstream proxy or browser caches aren't subjected to the same denial
      of service issue.

    Clients, serveurs et URLs
    



    
Les adresses des pages web sur la Toile se présentent sous forme d'URLs
- Uniform Resource Locators - qui comportent un protocole (par
  exemple http), un nom de serveur (par exemple
  www.apache.org), un chemin (par exemple
  /docs/current/getting-started.html), et le cas échéant
  une chaîne de paramètres (query string) (par exemple ?arg=value)
  permettant de transmettre des informations supplémentaires au serveur.

    


    Un client (par exemple un navigateur web) se connecte à un serveur
(par exemple votre serveur HTTP Apache) avec un protocole spécifique, et
effectue une requête pour une ressource en spécifiant
son chemin.
    


    Un chemin peut représenter plusieurs types de ressources sur le
serveur. Ce peut être un fichier (comme
getting-started.html), un gestionnaire (comme server-status), ou toute sorte de
programme (comme index.php). Nous décrirons tout ceci plus
en détails ci-dessous dans la section Contenu d'un
site web.
    


    
Le serveur envoie alors une réponse comportant un code
d'état, et éventuellement un corps de réponse. Le code d'état indique si
la requête a été traitée avec succès, ou dans la négative quel type
d'erreur a été rencontré. Le client est alors censé savoir quoi faire de
la réponse. Vous pouvez vous familiariser avec les différents codes
d'état en consultant le Wiki du
serveur HTTP Apache.
    


    Les détails de la transaction, ainsi que les erreurs rencontrées,
sont enregistrés dans des fichiers journaux. Tout ceci est décrit en
détails ci-dessous dans la section Débogage et fichiers
journaux.
    


    top
    

    

    Noms d'hôte et DNS
    



    Pour se connecter à un serveur, le client doit tout d'abord traduire
le nom du serveur en adresse IP, cette dernière permettant de localiser
le serveur sur Internet. Ainsi, pour que votre serveur web soit
accessible, son nom doit être enregistré dans le DNS.
    


    Si vous ne savez pas comment effectuer cet enregistrement, vous
devez contacter votre administrateur réseau ou votre fournisseur
d'accès à Internet afin qu'il effectue cette opération pour vous.
    


    Plusieurs noms d'hôte peuvent pointer vers la même adresse IP, et
plusieurs adresses IP peuvent être attachées au même serveur physique.
Vous pouvez ainsi héberger plusieurs serveurs web sur le même serveur
physique grâce au mécanisme des serveurs virtuels.
    


    Pour tester un serveur non encore accessible sur Internet, vous
pouvez renseigner son nom d'hôte dans votre fichier hosts afin
d'effectuer une résolution de nom locale. Par exemple, pour tester le
serveur web www.example.com depuis le serveur physique qui
l'héberge, vous pouvez ajouter la ligne suivante au fichier hosts de ce
dernier : 
    


    
127.0.0.1 www.example.com

    


    En général, le fichier hosts se trouve dans le répertoire
/etc sur les systèmes de style Unix, ou
C:\Windows\system32\drivers\etc sous Windows.
    


    Vous trouverez plus de détails à propos du fichier hosts à Wikipedia.org/wiki/Hosts_(file),
et à propos du DNS à Wikipedia.org/wiki/Domain_Name_System.

    Fichiers de configuration et directives
    



    La configuration du serveur HTTP Apache s'effectue via de simples
fichiers textes. Ces fichiers peuvent se trouver dans de nombreux
endroits différents en fonction du mode d'installation du serveur. Vous
trouverez les positions courantes de ces fichiers dans le wiki httpd.
Si vous installez httpd depuis le code source, le répertoire par défaut
des fichiers de configuration est /usr/local/apache2/conf.
Le nom du fichier de configuration par défaut est en général
httpd.conf, mais peut aussi varier en fonction des
distributions tierces du serveur.
    


    L'ensemble de la configuration est en général divisé en plusieurs
fichiers afin d'en faciliter la gestion. Ces fichiers sont inclus dans
le fichier de configuration principal via la directive Include. Les noms ou positions de ces fichiers
ne sont pas figés et peuvent varier considérablement d'une distribution
à l'autre. N'hésitez pas à les arranger et subdiviser selon
vos goûts et besoins, quitte à en modifier
l'organisation par défaut.
    


    La configuration du serveur s'effectue via des directives de configuration que l'on
insère dans les fichiers de configuration. Une directive se compose d'un
mot-clé suivi d'un ou plusieurs arguments qui définissent sa valeur.
    


    La réponse à la question "Où dois-je placer cette directive
?" dépend en général du niveau auquel cette directive doit être
prise en compte. S'il s'agit du niveau global, elle doit être placée
dans le fichier de configuration principal, et en dehors de toute
section  <Directory>, <Location>, <VirtualHost>, ou de toute autre section. Si
par exemple elle ne doit s'appliquer qu'à un répertoire particulier,
elle doit être placée dans la section <Directory> qui fait référence à ce répertoire.
Voir la documentation sur les Sections de
configuration pour plus de détails.
    


    En complément des fichiers de configuration principaux, certaines
directives peuvent être insérées dans des fichiers
.htaccess que l'on place directement dans le répertoire
concerné. Les fichiers .htaccess sont essentiellement
destinés aux personnes qui n'ont pas accès aux fichiers de configuration
du serveur. Vous trouverez plus de détails à propos des fichiers
.htaccess dans ce .htaccesshowto.

    Contenu du site web
    



    Si le contenu du site web peut se présenter sous de nombreuses
formes, il en existe deux principales : les
contenus statiques et les contenus dynamiques.
    


    Les contenus statiques sont par exemple les fichiers HTML, les
images, les fichiers CSS et tout autre fichier résidant dans le système
de fichiers. La directive DocumentRoot permet de définir la position
dans l'arborescence du site où vous devez placer ces fichiers. Cette
directive peut être définie au niveau global, ou au niveau de chaque
serveur virtuel. Vous pouvez consulter vos fichiers de configuration
pour vérifier la manière dont cette directive est définie pour votre
serveur.
    


    En général, et si aucun nom de fichier n'est spécifié dans la
requête, c'est une page de nom index.html qui sera
renvoyée. Par exemple, si la directive DocumentRoot est
définie à /var/www/html, et si une requête est effectuée
pour l'adresse http://www.example.com/work/, c'est le
fichier /var/www/html/work/index.html qui sera envoyé au
client par le serveur.
    


    Un contenu dynamique est un contenu qui est généré au moment du
traitement de la requête, et qui peut différer d'une requête à l'autre.
Ces contenus dynamiques peuvent être générés de nombreuses manières par
l'intermédiaire de gestionnaires de contenu
ou "handlers". Il est aussi possible de créer des programmes CGI pour générer le contenu de
votre site.
    


    Enfin, on peut utiliser des modules tiers comme mod_php pour écrire
du code permettant d'effectuer de nombreuses choses. De nombreuses
applications tierces écrites à partir de divers langages ou outils sont
disponibles en téléchargement et peuvent être installées sur votre
serveur HTTP Apache. Le support de ces applications est en dehors du sujet de
ce document, et nous vous invitons à consulter le site de leur éditeur
pour accéder à leur documentation.

    Fichiers journaux et résolution des problèmes
    


    En tant qu'administrateur d'un serveur HTTP Apache, vos sources
d'informations principales sont les fichiers journaux, et en particulier
le journal des erreurs. Toute tentative de résolution d'un problème sans
consulter le journal des erreurs revient à essayer de conduire les yeux
fermés.
    


    La position dans le système de fichiers du journal des erreurs est
spécifiée par la directive ErrorLog
qui peut être définie au niveau global, ou au niveau de chaque serveur
virtuel. Chaque entrée du journal des erreurs vous informe sur la nature
des problèmes et le moment de leur survenue. En outre, elle vous indique
souvent comment résoudre le problème. Chaque message d'erreur contient
un code d'erreur que vous pouvez utiliser pour effectuer une recherche
en ligne afin d'obtenir une description plus détaillée de la manière de
résoudre le problème. Vous pouvez aussi configurer votre journal des
erreurs de manière à ce qu'il enregistre un identifiant d'erreur que
vous pourrez ensuite utiliser pour effectuer une corrélation avec le
journal des accès afin de déterminer quelle requête est à l'origine de
l'erreur.
    


    Vous trouverez plus de détails à ce sujet dans la Documentation sur la journalisation.

    Et maintenant, comment faire pour aller plus loin ?
    



    La question des prérequis étant réglée, il est temps de passer aux
choses sérieuses.
    


    Ce document ne couvre que les notions de base. Nous espérons qu'il
vous permettra de mettre le pied à l'étrier, mais il y a encore de
nombreuses choses que vous devez savoir.

    Definitions
    

  
    
    
    Access Control
    
    
    The restriction of access to network realms. In an Apache context
      usually the restriction of access to certain URLs.
     See:  Authentication, Authorization, and Access
      Control
    
    

    
    Algorithm
    
    
    An unambiguous formula or set of rules for solving a problem in a finite
      number of steps. Algorithms for encryption are usually called
      Ciphers.
    
    

    
    APache
        eXtension Tool (apxs)
    
    
    A perl script that aids in compiling module sources into Dynamic Shared Objects
      (DSOs) and helps install them in the
      Apache Web server.
    
      See: Manual Page: apxs
    
    

    
    Apache Portable Runtime (APR)
    
    
    A set of libraries providing many of the basic interfaces
      between the server and the operating system.  APR is developed
      parallel to the Apache HTTP Server as an independent project.
    
      See: Apache Portable Runtime
      Project
    
    

    
    Authentication
    
    
    The positive identification of a network entity such as a server, a
      client, or a user.
    
      See: Authentication, Authorization, and Access
      Control
    
    

    
    Certificate
    
    
    A data record used for authenticating network entities such
      as a server or a client. A certificate contains X.509 information pieces
      about its owner (called the subject) and the signing Certification Authority (called
      the issuer), plus the owner's public
      key and the
      signature made by the CA. Network entities verify these signatures
      using CA certificates.
    
      See: SSL/TLS Encryption
    
    

    
    Certificate Signing Request
      (CSR)
    
    
    An unsigned certificate for
      submission to a Certification
      Authority, which signs it with the Private Key of their CA
      Certificate. Once the CSR is signed, it becomes a real
      certificate.
    
      See: SSL/TLS Encryption
    
    

    
    Certification Authority
      (CA)
    
    
    A trusted third party whose purpose is to sign certificates for network
      entities it has authenticated using secure means. Other network entities
      can check the signature to verify that a CA has authenticated the bearer
      of a certificate.
    
      See: SSL/TLS Encryption
    
    

    
    Cipher
    
    
    An algorithm or system for data encryption. Examples are DES, IDEA, RC4,
      etc.
    
      See: SSL/TLS Encryption
    
    

    
    Ciphertext
    
    
    The result after Plaintext is
      passed through a Cipher.
     See: SSL/TLS Encryption
    
    

    
    Common
        Gateway Interface (CGI)
    
    
    A standard definition for an interface between a web server and an
      external program that allows the external program to service requests.
      There is an Informational
      RFC which covers the specifics.
    
      See: Dynamic Content with CGI
    
    

    
    Configuration Directive
    
    
    See: Directive
    

    
    Configuration
        File
    
    
    A text file containing Directives
      that control the configuration of Apache.
    
      See: Configuration Files
    
    

    
    CONNECT
    
    
    An HTTP method for proxying raw data
      channels over HTTP. It can be used to encapsulate other protocols, such as
      the SSL protocol.
    
    

    
    Context
    
    
    An area in the configuration
      files where certain types of directives are allowed.
    
      See: Terms Used to Describe
      Apache Directives
    
    

    
    Digital
        Signature
    
    
    An encrypted text block that validates a certificate or other file. A
      Certification Authority
      creates a signature by generating a hash of the Public Key
      embedded in a Certificate, then encrypting the hash with its own
      Private Key. Only the CA's public key can decrypt the signature,
      verifying that the CA has authenticated the network entity that owns the
      Certificate.
    
      See: SSL/TLS Encryption
    
    

    
    Directive
    
    
    A configuration command that controls one or more aspects of Apache's
      behavior.  Directives are placed in the Configuration File
    
    See: Directive Index
    
    

    
    Dynamic
        Shared Object (DSO)
    
    
    Modules compiled separately from the
      Apache httpd binary that can be loaded on-demand.
    
      See: Dynamic Shared Object Support
    
    

    
    Environment
        Variable (env-variable)
    
    
    Named variables managed by the operating system shell and used to store
      information and communicate between programs.  Apache also contains
      internal variables that are referred to as environment variables, but are
      stored in internal Apache structures, rather than in the shell
      environment.
    
      See: Environment Variables in Apache
    
    

    
    Export-Crippled
    
    
    Diminished in cryptographic strength (and security) in order to comply
      with the United States' Export Administration Regulations (EAR).
      Export-crippled cryptographic software is limited to a small key size,
      resulting in Ciphertext which usually can be decrypted by brute
      force.
    
      See: SSL/TLS Encryption
    
    

    
    Filter
    
    
    A process that is applied to data that is sent or received by the
      server.  Input filters process data sent by the client to the server,
      while output filters process documents on the server before they are sent
      to the client.  For example, the INCLUDES output filter
      processes documents for Server Side
      Includes.
    
      See: Filters
    
    

    
    Fully-Qualified Domain-Name
      (FQDN)
    
    
    The unique name of a network entity, consisting of a hostname and a
      domain name that can resolve to an IP address. For example,
      www is a hostname, example.com is a domain name,
      and www.example.com is a fully-qualified domain name.
    
    

    
    Handler
    
    
    An internal Apache representation of the action to be performed when a
      file is called. Generally, files have implicit handlers, based on the file
      type. Normally, all files are simply served by the server, but certain
      file types are "handled" separately.  For example, the
      cgi-script handler designates files to be processed as
      CGIs.
    
      See: Apache's Handler Use
    
    

    
    Hash
    
    
    A mathematical one-way, irreversible algorithm generating a string with
      fixed-length from another string of any length. Different input strings
      will usually produce different hashes (depending on the hash function).
    
    

    
    Header
    
    
    The part of the HTTP request and
      response that is sent before the actual content, and that contains
      meta-information describing the content.
    
    

    
    .htaccess
    
    
    A configuration file that
      is placed inside the web tree and applies configuration directives to the directory where it is
      placed and all sub-directories.  Despite its name, this file can hold
      almost any type of directive, not just access-control directives.
    
      See: Configuration Files
    
    

    
    httpd.conf
    
    
    The main Apache configuration
      file.  The default location is
      /usr/local/apache2/conf/httpd.conf, but it may be moved using
      run-time or compile-time configuration.
    
      See: Configuration Files
    
    

    
    HyperText Transfer Protocol
      (HTTP)
    
    
    The standard transmission protocol used on the World Wide Web.  Apache
      implements version 1.1 of the protocol, referred to as HTTP/1.1 and
      defined by RFC 2616.
    
    

    
    HTTPS
    
    
    The HyperText Transfer Protocol (Secure), the standard encrypted
      communication mechanism on the World Wide Web. This is actually just HTTP
      over SSL.
    
      See: SSL/TLS Encryption
    
    

    
    Method
    
    
    In the context of HTTP, an action to
      perform on a resource, specified on the request line by the client.  Some
      of the methods available in HTTP are GET, POST,
      and PUT.
    
    

    
    Message Digest
    
    
    A hash of a message, which can be used to verify that the contents of
      the message have not been altered in transit.
    
      See: SSL/TLS Encryption
    
    

    
    MIME-type
    
    
    A way to describe the kind of document being transmitted.  Its name
      comes from that fact that its format is borrowed from the Multipurpose
      Internet Mail Extensions.  It consists of a major type and a minor type,
      separated by a slash.  Some examples are text/html,
      image/gif, and application/octet-stream.  In
      HTTP, the MIME-type is transmitted in the Content-Type
      header.
    
      See: mod_mime
    
    

    
    Module
    
    
    An independent part of a program.  Much of Apache's functionality is
      contained in modules that you can choose to include or exclude.  Modules
      that are compiled into the Apache httpd binary are
      called static modules, while modules that are stored
      separately and can be optionally loaded at run-time are called
      dynamic modules or DSOs.
      Modules that are included by default
      are called base modules. Many modules are available for Apache
      that are not distributed as part of the Apache HTTP Server tarball.  These are referred to as
      third-party modules.
    
      See: Module Index
    
    

    
    Module Magic
      Number (MMN)
    
    
    Module Magic Number is a constant defined in the Apache source code that
      is associated with binary compatibility of modules. It is changed when
      internal Apache structures, function calls and other significant parts of
      API change in such a way that binary compatibility cannot be guaranteed
      any more. On MMN change, all third party modules have to be at least
      recompiled, sometimes even slightly changed in order to work with the new
      version of Apache.
    
    

    
    OpenSSL
    
    
    The Open Source toolkit for SSL/TLS
    
      See http://www.openssl.org/#
    
    

    
    Pass Phrase
    
    
    The word or phrase that protects private key files. It prevents
      unauthorized users from encrypting them. Usually it's just the secret
      encryption/decryption key used for Ciphers.
    
      See: SSL/TLS Encryption
    
    

    
    Plaintext
    
    
    The unencrypted text.
    

    
    Private Key
    
    
    The secret key in a Public Key
      Cryptography system, used to decrypt incoming messages and
      sign outgoing ones.
    
      See: SSL/TLS Encryption
    
    

    
    Proxy
    
    
    An intermediate server that sits between the client and the origin
        server.  It accepts requests from clients, transmits those requests
      on to the origin server, and then returns the response from the origin
      server to the client.  If several clients request the same content, the
      proxy can deliver that content from its cache, rather than requesting it
      from the origin server each time, thereby reducing response time.
    
      See: mod_proxy
    
    

    
    Public Key
    
    
    The publicly available key in a Public Key Cryptography system,
      used to encrypt messages bound for its owner and to decrypt signatures
      made by its owner.
    
      See: SSL/TLS Encryption
    
    

    
    Public Key Cryptography
    
    
    The study and application of asymmetric encryption systems, which use
      one key for encryption and another for decryption. A corresponding pair of
      such keys constitutes a key pair. Also called Asymmetric Cryptography.
      
    
      See: SSL/TLS Encryption
    
    

    
    Regular Expression
      (Regex)
    
    
    A way of describing a pattern in text - for example, "all the words that
      begin with the letter A" or "every 10-digit phone number" or even "Every
      sentence with two commas in it, and no capital letter Q". Regular
      expressions are useful in Apache because they let you apply certain
      attributes against collections of files or resources in very flexible ways
      - for example, all .gif and .jpg files under any "images" directory could
      be written as "/images/.*(jpg|gif)$".  In places where
      regular expressions are used to replace strings, the special variables
      $1 ... $9 contain backreferences to the grouped parts (in parentheses) of
      the matched expression. The special variable $0 contains a backreference
      to the whole matched expression. To write a literal dollar sign in a
      replacement string, it can be escaped with a backslash. Historically, the
      variable & could be used as alias for $0 in some places. This is no
      longer possible since version 2.3.6.  Apache uses Perl Compatible Regular
      Expressions provided by the PCRE
      library.  You can find more documentation about PCRE's regular expression
      syntax at that site, or at
      Wikipedia.
    
    

    
    Reverse Proxy
    
    
    A proxy server that appears to the client
      as if it is an origin server.  This is useful to hide the real
      origin server from the client for security reasons, or to load balance.
    
    

    
    Secure Sockets
        Layer (SSL)
    
    
    A protocol created by Netscape Communications Corporation for general
      communication authentication and encryption over TCP/IP networks.  The most
      popular usage is HTTPS, i.e. the HyperText Transfer Protocol (HTTP)
      over SSL.
    
      See: SSL/TLS Encryption
    
    

    
    Server Name
        Indication (SNI)
    
    
    An SSL function that allows passing the desired server
      hostname in the initial SSL handshake message, so that the web
      server can select the correct virtual host configuration to use
      in processing the SSL handshake.  It was added to SSL starting
      with the TLS extensions, RFC 3546.  
    
      See: the SSL FAQ
      and RFC 3546
    
    

    
    Server Side
        Includes (SSI)
    
    
    A technique for embedding processing directives inside HTML files.
    
      See: Introduction to Server Side Includes
    
    

    
    Session
    
    
    The context information of a communication in general.
    

    
    SSLeay
    
    
    The original SSL/TLS implementation library developed by Eric A.
      Young
    
    

    
    Subrequest
    
    
    Apache provides a subrequest API to modules that allows other
        filesystem or URL paths to be partially or fully evaluated by
        the server. Example consumers of this API are 
        DirectoryIndex, 
        mod_autoindex, and mod_include.
    
    

    
    Symmetric
        Cryptography
    
    
    The study and application of Ciphers that use a single secret key
      for both encryption and decryption operations.
    
      See: SSL/TLS Encryption
    
    

    
    Tarball
    
    
    A package of files gathered together using the tar utility.
      Apache distributions are stored in compressed tar archives or using
      pkzip.
    
    

    
    Transport
        Layer Security (TLS)
    
    
    The successor protocol to SSL, created by the Internet Engineering Task
      Force (IETF) for general communication authentication and encryption over
      TCP/IP networks. TLS version 1 is nearly identical with SSL version 3.
    
      See: SSL/TLS Encryption
    
    

    
    Uniform
        Resource Locator (URL)
    
    
    The name/address of a resource on the Internet.  This is the common
      informal term for what is formally called a Uniform Resource Identifier.
      URLs are usually made up of a scheme, like http or
      https, a hostname, and a path.  A URL for this page might
      be http://httpd.apache.org/docs/2.4/glossary.html.
    
    

    
    Uniform Resource Identifier
      (URI)
    
    
    A compact string of characters for identifying an abstract or physical
      resource.  It is formally defined by RFC 2396.  URIs used on the
      world-wide web are commonly referred to as URLs.
    
    

    
    Virtual Hosting
    
    
    Serving multiple websites using a single instance of Apache.  IP
      virtual hosting differentiates between websites based on their IP
      address, while name-based virtual hosting uses only the name of the
      host and can therefore host many sites on the same IP address.
    
      See: Apache Virtual Host documentation
    
    

    
    X.509
    
    
    An authentication certificate scheme recommended by the International
      Telecommunication Union (ITU-T) which is used for SSL/TLS authentication.
     See: SSL/TLS Encryption

    Pour véritablement gérer un serveur web,
    il est nécessaire de disposer d'un
    retour d'informations à propos de l'activité et des performances du
    serveur, ainsi que de tout problème qui pourrait survenir. Le serveur HTTP
    Apache propose des fonctionnalités de journalisation souples et très
    complètes. Ce document décrit comment configurer ces fonctionnalités de
    journalisation et interpréter le contenu des journaux.

    Vue d'ensemble
    
    

  
    Modules ApparentésDirectives Apparentées
    

  
    
  Le serveur HTTP Apache fournit toute une variété de mécanismes
  différents pour la journalisation de tout ce qui peut se passer au
  sein de votre serveur, depuis la requête initiale, en passant par le
  processus de mise en correspondance des URLs, et jusqu'à la fermeture
  de la connexion, y compris toute erreur pouvant survenir au cours du
  traitement. De plus, certains modules tiers fournissent des
  fonctionnalités de journalisation ou insèrent des entrées dans les
  fichiers journaux existants, et les applications comme les programmes
  CGI, les scripts PHP ou autres gestionnaires peuvent envoyer des
  messages vers le journal des erreurs du serveur.
  
    

  
    
  Ce document décrit le fonctionnement des modules de journalisation
  fournis en standard avec le serveur httpd.

    Avertissement à propos de la sécurité
    
    

    
    Tout utilisateur qui a les droits en écriture sur le répertoire dans
    lequel Apache httpd écrit ses journaux pourra quasi
    certainement avoir accès à l'uid sous lequel le serveur est démarré, en
    l'occurrence habituellement root. N'accordez PAS aux utilisateurs
    l'accès en écriture au répertoire dans lequel les journaux sont stockés
    sans savoir exactement quelles en seraient les conséquences ; voir le
    document conseils sur la sécurité
    pour plus de détails.
    

    
    En outre, les journaux peuvent contenir des informations fournies
    directement par un client, sans caractères d'échappement. Des clients mal
    intentionnés peuvent donc insérer des caractères de contrôle dans les
    journaux, et il convient par conséquent d'être très prudent lors de la
    manipulation des journaux bruts.

    Journal des erreurs
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Le journal des erreurs du serveur, dont le nom et la localisation sont
    définis par la directive ErrorLog,
    est le journal le plus important. C'est dans celui-ci
    que le démon Apache httpd va envoyer les informations de diagnostic et
    enregistrer toutes les erreurs qui surviennent lors du traitement des
    requêtes. Lorsqu'un problème survient au démarrage du serveur ou pendant
    son fonctionnement, la première chose à faire est de regarder dans ce
    journal, car il vous renseignera souvent sur le problème rencontré et
    la manière d'y remédier.
    

    
    Le journal des erreurs est habituellement enregistré dans un fichier
    (en général error_log sur les systèmes de type Unix et
    error.log sur Windows et OS/2). Sur les systèmes de type Unix,
    le serveur peut aussi enregistrer ses erreurs dans
    syslog ou les
    rediriger vers un programme par l'intermédiaire d'un
    tube de communication (pipe).
    

    
    Le format par défaut du journal des erreurs est descriptif et de forme
    relativement libre. Certaines informations apparaissent cependant dans la
    plupart des entrées du journal. Voici un message typique
    à titre d'exemple : 
    

    
    
      [Wed Oct 11 14:32:52 2000] [error] [client 127.0.0.1]
      client denied by server configuration:
      /export/home/live/ap/htdocs/test
    
    

    
    Le premier champ de l'entrée du journal est la date et l'heure du
    message. Le second champ indique la sévérité de l'erreur rapportée. La
    directive LogLevel permet de
    restreindre le type des erreurs qui doivent être enregistrées
    dans le journal des erreurs en définissant leur niveau de sévérité. Le
    troisième champ contient l'adresse IP du client qui a généré l'erreur.
    Vient ensuite le message proprement dit, qui indique dans ce cas que le
    serveur a été configuré pour interdire l'accès au client. Le serveur
    indique le chemin système du document requis (et non
    son chemin web).
    

    
    Une grande variété de messages différents peuvent apparaître dans le
    journal des erreurs. La plupart d'entre eux sont similaires à l'exemple
    ci-dessus. Le journal des erreurs peut aussi contenir des informations de
    débogage en provenance de scripts CGI. Toute information qu'un script CGI
    écrit sur la sortie d'erreurs standard stderr sera recopiée
    telle quelle dans le journal des erreurs.
    

    
    La directive ErrorLogFormat
    vous permet de personnaliser le format du journal des erreurs, et de
    définir les informations à journaliser. Si
    mod_unique_id est présent, vous pouvez utiliser le
    drapeau %L à la fois dans le journal des erreurs et
    dans le
    journal des accès, ce qui aura pour effet de générer un identifiant
    d'entrée qui vous permettra de corréler les entrées du journal des
    erreurs avec celles du journal des accès.
    

    
    Pendant la phase de test, il est souvent utile de visualiser en continu
    le journal des erreurs afin de détecter tout problème éventuel. Sur les
    systèmes de type Unix, ceci s'effectue à l'aide de la commande :
    

    
    
      tail -f error_log
    
    
  
    top
    

    

    Journalisation par module
    
    

    
    La directive LogLevel permet
    de spécifier un niveau de sévérité de journalisation pour chaque
    module. Vous pouvez ainsi résoudre un problème propre à un module particulier
    en augmentant son volume de journalisation sans augmenter ce volume
    pour les autres modules. Ceci est particulièrement utile lorsque
    vous voulez obtenir des détails sur le fonctionnement de modules
    comme mod_proxy ou mod_rewrite.
    

    
    Pour ce faire, vous devez spécifier le nom du module dans votre
    directive LogLevel :
    

    
    LogLevel info rewrite:trace5
    


    
    Dans cet exemple, le niveau de journalisation général est défini
    à info, et à trace5 pour mod_rewrite.
    

    
    Cette directive remplace les directives de journalisation par
    module des versions précédentes du serveur, comme
    RewriteLog.
    
 
    top
    

    

    Journal des accès
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Le journal des accès au serveur
    enregistre toutes les requêtes que traite
    ce dernier. La localisation et le contenu du journal des accès sont définis
    par la directive CustomLog.
    La directive LogFormat
    permet de simplifier la sélection du contenu du journal. Cette section
    décrit comment configurer le serveur pour l'enregistrement des informations
    dans le journal des accès.
    

    
    Bien évidemment, le stockage d'informations dans le journal des accès
    n'est que le point de départ de la gestion de la journalisation. L'étape
    suivante consiste à analyser ces informations de façon à pouvoir en
    extraire des statistiques utiles. L'analyse de journaux en général est en
    dehors du sujet de ce document et ne fait pas vraiment partie intégrante
    du travail du serveur web lui-même. Pour plus d'informations à propos de ce
    sujet et des applications dédiées à l'analyse de journaux, vous pouvez vous
    référer à Open Directory.
    

    
    Différentes versions du démon Apache httpd utilisaient d'autres modules
    et directives pour contrôler la journalisation des accès, à l'instar de
    mod_log_referer, mod_log_agent, et de la directive
    TransferLog. La directive
    CustomLog rassemble
    désormais les fonctionnalités de toutes les anciennes directives.
    

    
    Le format du journal des accès est hautement configurable. Il est
    défini à l'aide d'une chaîne de format qui ressemble sensiblement à la
    chaîne de format de style langage C de printf(1). Vous trouverez quelques
    exemples dans les sections suivantes. Pour une liste exhaustive de ce que
    peut contenir une chaîne de format, vous pouvez vous référer au chapitre
    chaînes de format de la
    documentation du module mod_log_config.
    

    
    Format habituel du journal
    
      

      
    Voici une configuration typique pour le journal des accès :
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog logs/access_log common
    


      
    Ici est définie l'identité common qui est
      ensuite associée à une chaîne de format de journalisation particulière.
      La chaîne de format est constituée de directives débutant par le
      caractère %, chacune d'entre elles indiquant au serveur d'enregistrer
      un élément particulier d'information. Des caractères littéraux peuvent
      aussi être insérés dans la chaîne de format ; il seront copiés tels
      quels dans le flux de sortie destiné à la journalisation.
      Les guillemets (") doivent être échappées en les faisant
      précéder d'un anti-slash (\) afin qu'elles ne soient pas
      interprétées comme la fin de la chaîne de format. La chaîne de format
      peut aussi contenir les caractères de contrôle spéciaux
      "\n" et "\t" pour insérer respectivement
      un passage à la ligne et une tabulation.
    

      
    La directive CustomLog
      définit un nouveau fichier journal en l'associant à l'identité
      précédemment définie. Le chemin du nom de fichier associé au journal
      des accès est relatif au chemin défini par la directive
      ServerRoot, sauf s'il
      débute par un slash.
    

      
    La configuration ci-dessus va enregistrer les entrées de
      journalisation selon un format connu sous le nom de
      Common Log Format (CLF) pour "Format de journalisation standard".
      Ce format standard peut être produit par de nombreux serveurs web
      différents et lu par de nombreux programmes d'analyse de journaux.
      Les entrées de fichier journal générées selon le format CLF
      ressemblent à ceci :
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
      
    

      
    Chaque partie de cette entrée de journal est décrite
      dans ce qui suit.
    

      
    
        
    127.0.0.1 (%h)
    

        
    Il s'agit de l'adresse IP du client (l'hôte distant) qui a envoyé
	la requête au serveur. Si la directive
	HostnameLookups est positionnée à
	On, le serveur va essayer de déterminer le nom de l'hôte
	et de l'enregistrer à la place de l'adresse IP. Cette configuration
	n'est cependant pas recommandée car elle peut ralentir le serveur de
	manière significative. Il est par conséquent préférable d'utiliser un
	processeur d'analyse de journaux a posteriori
	tel que logresolve
	pour déterminer les noms d'hôte. L'adresse IP indiquée ici n'est pas
	nécessairement l'adresse IP de la machine devant laquelle se trouve
	l'utilisateur. Si un serveur mandataire s'intercale entre le serveur
	et l'utilisateur, l'adresse indiquée sera celle du mandataire et non
	celle de la machine à l'origine de la requête.
    

        
    - (%l)
    

        
    Le "trait d'union" indique que la portion d'information
	correspondante n'est pas disponible. Dans le cas présent, l'information
	non disponible est l'identité (RFC 1413) du client telle que déterminée
	par identd sur la machine cliente. Cette information est
	très peu fiable et ne devrait jamais être utilisée, sauf dans le cas
	de réseaux internes étroitement contrôlés. Le démon httpd ne cherchera
	d'ailleurs à obtenir cette information que si la directive
	IdentityCheck est positionnée
	à On.
    

        
    frank (%u)
    

        
    Il s'agit de l'identifiant utilisateur de la personne qui a
	demandé le document, issu d'une authentification HTTP.
	Ce même identifiant est en général fourni aux scripts CGI par
	l'intermédiaire de la valeur de la variable d'environnement
	REMOTE_USER. Si le statut de la requête (voir plus loin)
	est 401, cette identifiant n'est pas fiable car l'utilisateur n'est
	pas encore authentifié. Si le document n'est pas protégé par
	mot de passe, cette partie d'information sera représentée par
	"-", comme la partie précédente.
    

        
    [10/Oct/2000:13:55:36 -0700]
        (%t)
    

        
    
          L'heure à laquelle la requête a été reçue.
          Le format est le suivant :

          
    
            [jour/mois/année:heure:minutes:secondes zone]
    
             jour = 2*chiffre
    
             mois = 3*lettre
    
             année = 4*chiffre
    
             heure = 2*chiffre
    
             minutes = 2*chiffre
    
             secondes = 2*chiffre
    
             zone = (`+' | `-') 4*chiffre    
          
    Il est possible de modifier le format d'affichage de l'heure
	  en spécifiant %{format}t dans la chaîne de format du
	  journal, où format est une chaîne de format
	  de la forme de celle de la fonction strftime(3)
	  de la bibliothèque C standard, ou choisie parmi les
	  formats spéciaux supportés. Pour plus de détails,
	  reportez-vous aux. chaînes de format
	  de mod_log_config.
        
    

        
    "GET /apache_pb.gif HTTP/1.0"
        (\"%r\")
    

        
    La ligne de la requête du client est placée entre guillemets.
	Elle contient de nombreuses informations utiles. Tout d'abord, la
	méthode utilisée par le client est GET. Ensuite, le
	client a demandé la ressource /apache_pb.gif, et enfin,
	le client a utilisé le protocole HTTP/1.0. Il est aussi
	possible d'enregistrer séparément une ou plusieurs parties de la
	requête. Par exemple, la chaîne de format "%m %U %q %H"
	va enregistrer la méthode, le chemin, la chaîne de la requête et le
	protocole, ce qui donnera le même résultat que
	"%r".
    

        
    200 (%>s)
    

        
    C'est le code de statut que le serveur retourne au client. Cette
	information est très importante car elle indique si la requête a fait
	l'objet d'une réponse positive (codes commençant par 2), une
	redirection (codes commençant par 3), une erreur due au client (codes
	commençant par 4), ou une erreur due au serveur (codes commençant
	par 5). Vous trouverez la liste complète des codes de statut possibles
	dans la specification HTTP (RFC2616 section 10).
    

        
    2326 (%b)
    

        
    La dernière partie indique la taille de l'objet retourné au client,
	en-têtes non compris. Si aucun contenu n'a été retourné au client, cette
	partie contiendra "-". Pour indiquer l'absence de contenu
	par "0", utilisez %B au lieu de
	%b.
    
      
    
    

    
    Combined Log Format (Format de journalisation combiné)
    
      

      
    Une autre chaîne de format couramment utilisée est le
      "Combined Log Format" (Format de journalisation combiné). Il s'utilise
      comme suit :
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined
CustomLog log/access_log combined
    


      
    Ce format est identique au Common Log Format, avec deux champs
      supplémentaires. Chacun de ces deux champs utilise la directive
      commençant par le caractère "%" %{header}i,
      où header peut être n'importe quel en-tête de requête HTTP.
      Avec ce format, le journal des accès se présentera comme suit :
    

      
    
        127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET
        /apache_pb.gif HTTP/1.0" 200 2326
        "http://www.example.com/start.html" "Mozilla/4.08 [en]
        (Win98; I ;Nav)"
      
    

      
    Les champs supplémentaires sont :
    

      
    
        
    "http://www.example.com/start.html"
        (\"%{Referer}i\")
    

        
    L'en-tête "Referer" (sic) de la requête HTTP. Il indique le site
	depuis lequel le client prétend avoir lancé sa requête. (Ce doit être
	la page qui contient un lien vers /apache_pb.gif ou
	inclut ce dernier fichier).
    

        
    "Mozilla/4.08 [en] (Win98; I ;Nav)"
        (\"%{User-agent}i\")
    

        
    L'en-tête User-Agent de la requête HTTP. C'est une information
	d'identification que le navigateur du client envoie à propos
	de lui-même.
    
      
    
    

    
    Journaux d'accès multiples
    
      

      
    Plusieurs journaux d'accès peuvent être créés en spécifiant tout
      simplement plusieurs directives
      CustomLog dans le
      fichier de configuration. Par exemple, les directives suivantes vont
      créer trois journaux d'accès. Le premier contiendra les informations
      de base CLF, le second les informations du Referer, et le troisième
      les informations sur le navigateur. Les deux dernières directives
      CustomLog montrent
      comment simuler les effets des directives ReferLog et
      AgentLog.
    

      
    LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog logs/access_log common
CustomLog logs/referer_log "%{Referer}i -> %U"
CustomLog logs/agent_log "%{User-agent}i"
    


      
    Cet exemple montre aussi qu'il n'est pas obligatoire d'associer
      une chaîne de format à un alias au moyen de la directive
      LogFormat. Elle peut
      être définie directement dans la ligne de la directive
      CustomLog.
    
    

    
    Journalisation conditionnelle
    
      

      
    Il est parfois souhaitable d'exclure certaines entrées des journaux
      d'accès en fonction des caractéristiques de la requête du client. On
      peut aisément accomplir ceci à l'aide des
      variables d'environnement. Tout d'abord, une
      variable d'environnement doit être définie pour indiquer que la
      requête remplit certaines conditions. Pour ceci, on utilise en général
      la directive SetEnvIf,
      puis la clause env= de la directive
      CustomLog pour inclure
      ou exclure les requêtes pour lesquelles
      la variable d'environnement est définie.
      Quelques exemples :
    

      
    # Marque les requêtes en provenance de l'interface loop-back
SetEnvIf Remote_Addr "127\.0\.0\.1" dontlog
# Marque les requêtes pour le fichier robots.txt
SetEnvIf Request_URI "^/robots\.txt$" dontlog
# Journalise toutes les autres requêtes
CustomLog logs/access_log common env=!dontlog
    


      
    Autre exemple, imaginons l'enregistrement des requêtes en provenance
      d'utilisateurs de langue anglaise dans un journal, et celles des autres
      utilisateurs dans un autre journal.
    

      
            SetEnvIf Accept-Language "en" english
        CustomLog logs/english_log common env=english
        CustomLog logs/non_english_log common env=!english
    


	
    Dans le contexte d'une mise en cache, il peut être
	intéressant de connaître l'efficacité du cache. Pour y parvenir,
	on pourrait utiliser cette méthode simple :
    

      
    SetEnv CACHE_MISS 1
LogFormat "%h %l %u %t "%r " %>s %b %{CACHE_MISS}e" common-cache
CustomLog logs/access_log common-cache
    


      
    mod_cache va s'exécuter avant
      mod_env, et si son action est couronnée de
      succès, il délivrera le contenu sans faire appel à ce dernier. Si
      l'URL se trouve dans le cache, la valeur journalisée sera alors
      -, tandis que dans le cas contraire elle sera
      1.
    

      
    En plus de la syntaxe env=, la directive LogFormat supporte les
      valeurs de journalisation conditionnelles basées sur le code de la
      réponse HTTP :
    

      
    LogFormat "%400,501{User-agent}i" browserlog
LogFormat "%!200,304,302{Referer}i" refererlog
    


      
    Dans le premier exemple, le User-agent sera
      enregistré si le code d'état HTTP est 400 ou 501. Dans le cas
      contraire, c'est un caractère "-" qui sera enregistré à la place.
      Dans le second exemple, le Referer sera enregistré si
      le code d'état HTTP n'est pas 200, 204, ou 302
      (remarquez le caractère "!" avant les codes d'état).
    

      
    Bien que nous venions de montrer que la journalisation conditionnelle
      est souple et très puissante, cette méthode de contrôle du contenu des
      journaux n'est pas la seule. Les fichiers journaux sont plus utiles
      quand ils contiennent un enregistrement complet de l'activité du serveur,
      et il est souvent plus aisé de simplement traiter à posteriori les fichiers
      journaux pour supprimer les requêtes que vous ne voulez pas y voir
      apparaître.

    Rotation des journaux
    
    

    
    Même dans le cas d'un serveur modérément sollicité, la quantité
    d'informations stockées dans les fichiers journaux est très importante.
    Le fichier journal des accès grossit en général d'1 Mo ou plus toutes
    les 10000 requêtes. Il est par conséquent nécessaire d'effectuer
    périodiquement la rotation des journaux en déplaçant ou supprimant les
    fichiers correspondants. On ne peut pas le faire pendant que le serveur
    est en cours d'exécution, car Apache httpd va continuer à écrire dans l'ancien
    fichier journal aussi longtemps qu'il le maintiendra ouvert.
    C'est pourquoi le serveur doit être
    redémarré après le déplacement ou la
    suppression des fichiers journaux de façon à ce qu'il en ouvre
    de nouveaux.
    

    
    Avec un redémarrage graceful, on peut faire en sorte que le
    serveur ouvre de nouveaux fichiers journaux sans perdre de connexions
    existantes ou en cours avec les clients. Cependant, pour que ceci soit
    possible, le serveur doit continuer à écrire dans les anciens fichiers
    journaux pendant qu'il termine le traitement des requêtes en cours.
    Il est donc nécessaire d'attendre un certain temps après le rédémarrage
    avant d'effectuer tout traitement sur les fichiers journaux. Voici un
    scénario typique dans lequel on effectue une simple rotation des
    journaux en compressant les anciens fichiers correspondants afin
    de gagner de l'espace disque :
    

    
    
      mv access_log access_log.old
    
      mv error_log error_log.old
    
      apachectl graceful
    
      sleep 600
    
      gzip access_log.old error_log.old
    
    

    
    La section suivante présente une autre méthode de rotation des journaux
    qui consiste à utiliser les
    journaux redirigés.
    
  
    top
    

    

    Journaux redirigés
    
    

    
    Nous avons vu que le démon httpd écrivait les informations de
    journalisation des erreurs et des accès dans un fichier journal ;
    il peut aussi
    rediriger ces informations vers un autre processus par l'intermédiaire d'un
    tube de communication (pipe). Cette fonctionnalité améliore
    considérablement la souplesse de la journalisation, sans ajouter de code
    au serveur principal. Pour rediriger les informations de journalisation
    vers un tube de communication, remplacez simplement le nom de fichier
    journal par
    le caractère pipe "|", suivi du nom de l'exécutable qui va
    recueillir les entrées de journal sur son entrée
    standard. Le serveur va
    lancer le processus de redirection des journaux au moment du démarrage du
    serveur, et le relancera s'il cesse de fonctionner
    pendant l'exécution du serveur.
    (Nous dénommons cette technique "journalisation
    redirigée fiable" grâce à cette dernière fonctionnalité.)
    

    
    Les processus de journalisation redirigée sont lancés par le processus
    httpd parent, et héritent de l'UID de ce dernier. Cela signifie que les
    programmes de journalisation dirigée s'exécutent généralement en tant que
    root. Il est donc très important que ces programmes soient simples et
    sécurisés.
    

    
    Un des grands avantages de la journalisation redirigée est la possibilité
    d'effectuer la rotation des journaux sans avoir à redémarrer le serveur. Pour
    accomplir cette tâche, le serveur HTTP Apache fournit un programme simple
    appelé rotatelogs. Par exemple, pour une rotation des
    journaux toutes les 24 heures, ajoutez ces lignes :
    

    
    CustomLog "|/usr/local/apache/bin/rotatelogs /var/log/access_log 86400" common
    


    
    Notez que l'ensemble de la commande qui sera appelée par le tube de
    communication a été placée entre guillemets. Bien que cet exemple
    concerne le journal des accès, la même technique peut être utilisée
    pour le journal des erreurs.
    

    
    Comme la journalisation conditionnelle, la journalisation redirigée est
    un outil très puissant, mais si elle existe, il est préférable d'utiliser
    une solution plus simple comme le traitement à posteriori hors ligne.
    


  
    Par défaut, le processus de redirection du journal est lancé sans
  invoquer un shell. Pour invoquer un shell, utilisez "|$"
  au lieu de "|" (en général avec /bin/sh -c)
  :
    

    
    # Invocation de "rotatelogs" en utilisant un shell
CustomLog "|$/usr/local/apache/bin/rotatelogs   /var/log/access_log 86400" common
    



    
    Il s'agissait du comportement par défaut sous Apache 2.2. Selon
    les spécificités du shell, ceci peut générer un processus shell
    supplémentaire pour toute la durée du programme de redirection du
    journal, et induire des problèmes de gestion de signaux au cours du
    redémarrage. La notation "||" est aussi supportée pour
    des raisons de compatibilité avec Apache 2.2 et est équivalente à
    "|".
    

    
    Note à propos de la plateforme Windows
    
    
    Notez que sous Windows, la mémoire allouée au bureau (desktop
    heap) peut devenir insuffisante si vous utilisez de nombreux
    processus vers lesquels sont redirigés des journaux via un pipe, et
    ceci particulièrement si httpd s'exécute en tant que service. La
    quantité de mémoire du bureau allouée à chaque service est spécifiée
    dans le troisième argument du paramètre SharedSection
    de la clé de registre
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\SubSystems\Windows.
    Modifiez cette valeur avec prudence ; les
    précautions d'usage s'imposent lorsqu'on modifie la base de registre,
    mais vous pouvez aussi saturer la mémoire du bureau si vous
    spécifiez une valeur trop élevée.

    Hôtes virtuels
    
    

    
    Lorsqu'un serveur possède plusieurs hôtes virtuels, il existe de nombreuses solutions pour gérer
    les fichiers journaux. Par exemple, on peut utiliser les journaux comme
    s'il s'agissait d'un serveur avec un seul hôte. Il suffit pour cela de
    placer les directives de journalisation en dehors des sections
    <VirtualHost> au niveau
    du serveur principal, ce qui a pour effet de journaliser toutes les
    requêtes dans le même journal des accès et des erreurs. Cette technique
    est cependant inappropriée pour recueillir des statistiques sur chaque
    hôte virtuel individuellement.
    

    
    Si des directives CustomLog ou
    ErrorLog sont placées dans une section
    <VirtualHost>, toutes les
    requêtes ou erreurs pour cet hôte virtuel ne seront enregistrées que dans
    le fichier spécifié. Tout hôte virtuel qui ne possède pas de directives de
    journalisation verra ses requêtes enregistrées dans le journal du serveur
    principal. Cette technique est appropriée pour un petit nombre d'hôtes
    virtuels, mais si ce nombre est important, elle peut devenir compliquée à
    gérer. En outre, des problèmes de nombre de descripteurs
    de fichiers insuffisant peuvent rapidement apparaître.
    

    
    Il existe un très bon compromis pour le journal des accès. En intégrant
    les informations à propos de l'hôte virtuel à la chaîne de format du
    journal, il est possible de journaliser tous les hôtes dans le même
    journal, puis de séparer ultérieurement le journal en plusieurs journaux
    individuels. Considérons par exemple les directives suivantes :
    

    
    LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost
CustomLog logs/access_log comonvhost
    


    
    Le champ %v sert à enregistrer le nom de l'hôte virtuel qui
    traite la requête. Un programme tel que split-logfile peut ensuite être utilisé
    pour générer "à froid" autant de journaux que d'hôtes virtuels.

    Enregistrement du nombre réel d'octets envoyés et reçus
    
      

      
    Le module mod_logio fournit deux champs
      LogFormat supplémentaires
      (%I et %O) qui permettent d'enregistrer le nombre réel d'octets reçus et
      envoyés sur le réseau.
    
    

    
    Journalisation de style investigation judiciaire (forensic logging)
    
      

      
    Le module mod_log_forensic permet la journalisation
      à des fins d'investigation judiciaire des requêtes des clients. La
      journalisation est effectuée avant et après le traitement de la requête,
      qui fait donc l'objet de deux entrées dans le journal. Le générateur de
      journaux d'investigation est très strict et ne permet aucune
      personnalisation. C'est un inestimable outil de débogage et de sécurité.
    
    

    
    Fichier PID
    
      

      
    Au démarrage, le démon httpd Apache enregistre l'identifiant du
      processus httpd parent dans le fichier logs/httpd.pid.
      Le nom de ce fichier peut être modifié à l'aide de la directive
      PidFile. Cet identifiant
      permet à l'administrateur de redémarrer et arrêter le démon en
      envoyant des signaux au processus parent ; sous Windows, vous devez
      utiliser l'option de ligne de commande -k. Pour plus de détails,
      consulter la page Arrêt et redémarrage.
    
    

    
    Journal des scripts
    
      

      
    Afin de faciliter le débogage, la directive
      ScriptLog vous permet
      d'enregistrer les entrées et sorties des scripts CGI. Elle ne doit être
      utilisée que pendant la phase de test, et en aucun cas sur un
      serveur en production. Vous trouverez plus d'informations dans la
      documentation du module mod_cgi.

    Apache HTTPD sunucusunun belli adresleri ve portları dinlemek üzere
    yapılandırılması.
    
  
    


    top
    

    

    Genel Bakış
    
    

    
    İlgili Modüllerİlgili Yönergeler
    


    
    httpd başlatıldığında yerel makinedeki bazı adres ve portları kendine
      bağlar ve gelecek istekleri bekler. Öntanımlı olarak makine üzerindeki
      tüm adresleri dinler. Bununla birlikte, belli portları veya sadece
      seçilmiş bazı adresleri ya da her ikisini de dinlemesi için bunun
      belirtilmesi gerekebilir. Bu çoğunlukla, httpd’nin farklı IP
      adreslerine, konak isimlerine ve portlarına nasıl yanıt vereceğinin
      belirlendiği sanal konak özelliği ile birlikte
      yürür.
    

    
    Listen yönergesi sunucuya
      gelen istekleri sadece belli port(lar)dan veya belli adres ve port
      birleşimlerinden kabul etmesini söyler. Listen yönergesinde sadece port
      numarası belirtilmişse sunucu tüm arabirimlerin belirtilen portunu
      dinleyecektir. Portla birlikte bir IP adresi de belirtilmişse sunucu
      belirtilen portu ve arabirimi dinleyecektir. Çok sayıda adres ve portu
      dinlemek için çok sayıda Listen yönergesi kullanılabilir. Sunucu
      böyle bir durumda belirtilen bütün adres ve portlardan gelen isteklere
      yanıt verecektir.
    

    
    Örneğin, sunucunun hem 80 portundan hem de 8000 portundan gelen
      bağlantıları kabul etmesini sağlamak için,
    

    
    Listen 80
Listen 8000
    

    

    
    yapılandırmasını kullanabilirsiniz. Sunucunun 80 portuna gelen
      bağlantıları bir arabirimden 8000 portuna gelenleri ise başka bir
      arabirimden kabul etmesini sağlamak için ise,
    

    
    Listen 192.0.2.1:80
Listen 192.0.2.5:8000
    

    

    
    yapılandırmasını kullanabilirsiniz. IPv6 adresleri aşağıdaki örnekteki
      gibi köşeli ayraçlar içine alınarak belirtilmelidir:
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    

    

    
    
      
    Bir Listen yönergesinin
      aynısının tekrarı sunucunun başlatılmasını engelleyen ölümcül bir hatayla
      sonuçlanacaktır.
    

      
    
      (48)Address already in use: make_sock: could not bind to address [::]:80

    top
    

    

    Dinleme yapılandırmasının yeniden başlatırken değiştirilmesi
    
    

    
    httpd yeniden başlatılırken, 
    Listen yönergelerindeki 
    değişiklikler için özel değerlendirmeler yapılmalıdır. Yeniden başlatma 
    sırasında, httpd, yeni bağlanma çabalarında "Connection refused" (bağlantı 
    reddedildi) hatasından kaçınmak için [özgün yapılandırmadaki gibi] portları 
    bağlı tutar. Bu bakımdan, Listen
    yönergelerinden yapılan değişiklikler yenden başlatılrken yapılandırmanın 
    başarısız olmasına ve sunucunun sonlanmasına sebep olur.
    

    
    Örneğin:
    
    
    
    Listen 127.0.0.1:80
    

    

    
    yapılandırmasını aşağıdakiyle değiştirmek yenden başlatma sırasında 
    sucunun hta verip sonlanmasına sebep olur. Çünkü, tüm adreslerden 80 porta 
    bağlanmak sadece 127.0.0.1 adresine bağlanmakla çelişir.
    
    
    
    Listen 80
    

    

    
    Böyle değişikliklerin etkili olabilmesi için sunucu önce durdurulmalı 
    sonra başlatımalıdır (restart yerine stop ve start kullanılmalıdır).
    
    
  
    top
    

    

    IPv6 Adreslerin Durumu
    
    

    
    IPv6’yı gerçekleyen platformların sayısı giderek artmaktadır. Bu
      platformların çoğunda APR, httpd’nin IPv6
      soketleri ayırmasını mümkün kılarak IPv6’yı desteklemekte ve IPv6
      üzerinden gönderilmiş istekleri elde etmektedir.
    

    
    httpd yöneticilerinin kafasını karıştırıran tek şey IPv6 soketlerin
      hem IPv4 hem de IPv6 bağlantılarını kabul edip etmeyeceğidir. IPv4
      bağlantılarını kabul eden IPv6 soketleri IPv4 eşlemli IPv6 adresleri
      kullanırlar. Bu çoğu sistemde öntanımlı olarak böyleyken, FreeBSD,
      NetBSD ve OpenBSD’de sistem geneline uygulanan kurallar gereğince
      öntanımlı olarak buna izin verilmez; bu sistemlerde özel bir
      configure parametresi ile httpd’nin
      davranışı değiştirilebilir.
    

    
    Diğer taraftan, Linux ve Tru64 gibi bazı platformlarda hem IPv4 hem de
      IPv6 adresleri kabul etmenin tek yolu eşlemli adresler
      kullanmaktır. httpd’nin IPv4 ve IPv6 adresleri, IPv4 eşlemli
      IPv6 adreslerin kullanımını gerektiren en az sayıda soketle kabul etmesini
      istiyorsanız, configure betiğine
      --enable-v4-mapped seçeneğini belirtiniz.
    

    
    --enable-v4-mapped seçeneği, FreeBSD, NetBSD ve OpenBSD
      hariç tüm platformlarda öntanımlıdır. Muhtemelen siz de
      httpd’nin böyle derlenmesini isterdiniz.
    

    
    Platformunuzun ve APR’nin neyi desteklediğine bakmaksızın
      httpd’nin sadece IPv4 adresleri kabul etmesini istiyorsanız,
      tüm Listen yönergelerinde
      örnekteki gibi IPv4 adresleri belirtiniz:
    

    
    Listen 0.0.0.0:80
Listen 192.0.2.1:80
    

    

    
    Platformunuz IPv4 ve IPv6 adresleri ayrı soketlerden kabul ediyorsa ve
      httpd’nin de buna uygun davranmasını (yani IPv4 eşlemli IPv6
      adreslerin iptalini)  istiyorsanız configure
      betiğine --disable-v4-mapped seçeneğini belirtiniz. Bu
      seçenek FreeBSD, NetBSD ve OpenBSD’de öntanımlıdır.
    
  
    top
    

    

    Protokolü Listen ile Belirtme
    
    
    
    Listen yönergesinin isteğe
      bağlı ikinci değiştirgesi protokol çoğu yapılandırmada gerekli
      olmaz. Belirtilmediği takdirde, https için 443,
      http için ise diğer bütün portlar öntanımlıdır. Protokol,
      isteğin hangi modül tarafından işleneceğini ve AcceptFilter yönergesi ile uygulanacak
      protokole özgü en iyilemeleri belirlemekte kullanılır.
    

    
    Sadece standartdışı bir port kullanmak isterseniz protokolü belirtmeniz
      gerekir. Örneğin, birhttps sitesini port 8443 üzerinde
      çalıştırmak isterseniz:
    

    
    Listen 192.170.2.1:8443 https
    

    
  
    top
    

    

    Sanal Konaklarla Nasıl Çalışır?
    
    

    
    Listen yönergesi sanal
      konaklar için gerçeklenmemiştir; sadece ana sunucuya hangi adresleri ve
      portları dinleyeceğini söyler. Hiç <VirtualHost> yönergesi kullanılmamışsa sunucu
      kabul edilen tüm isteklere aynı şekilde davranacaktır. Eğer bir veya
      daha fazla adres ve port için farklı bir davranış belirtmek
      istiyorsanız <VirtualHost> kullanabilirsiniz. Bir sanal
      konağı gerçeklemek için önce sunucunun sanal konak için kullanacağı
      adres ve portu dinleyeceğini belirtmek gerekir. Bundan sonra bu sanal
      konağın davranışını ayarlamak üzere belirtilen adres ve port için bir
      <VirtualHost> bölümü
      oluşturulmalıdır. Yalnız dikkat edin, eğer <VirtualHost> için belirtilen adres ve port
      sunucu tarafından dinlenmiyorsa ona erişemezsiniz.

            nicht mehr aktuell. Bitte prüfen Sie die englische Version auf
            die neuesten Änderungen.
    

    
    Unter Windows läuft der Apache üblicherweise als Dienst
    (Windows NT, 2000 und XP) oder als Konsolenanwendung (Windows 9x und
    ME). Für Einzelheiten lesen Sie bitte Apache als Dienst betreiben
    und Apache als Konsolenanwendung betreiben.
    

    
    Unter Unix wird das httpd-Programm als Daemon
    ausgeführt, der im Hintergrund fortlaufend aktiv ist, um
    Anfragen zu bearbeiten. Dieses Dokument beschreibt, wie
    httpd aufgerufen wird.

    Wie der Apache startet
    

    
    Wenn die in der Konfigurationsdatei angegebene Listen-Anweisung auf die Voreinstellung
    von 80 gesetzt ist (oder einen anderen Port unterhalb von 1024), dann
    müssen Sie root-Berechtigung besitzen, um den Apache starten
    zu können. Nur dann kann er sich an diesen privilegierten
    Port binden. Sobald der Server gestartet ist und einige vorbereitende
    Aktionen wie das Öffnen seiner Log-Dateien ausgeführt hat,
    startet er mehrere Kind-Prozesse, welche die Arbeit erledigen:
    das Lauschen auf und Beantworten von Anfragen von Clients. Der
    Haupt-httpd-Prozess läuft unter dem Benutzer root
    weiter, die Kind-Prozesse jedoch werden unter weniger privilegierten
    Benutzerkennungen ausgeführt. Dies wird von dem ausgewählten
    Multi-Processing-Modul gesteuert.
    

    
    Die Verwendung des Steuerskripts apachectl ist die
    empfohlene Methode, das httpd-Programm zu starten.
    Dieses Skript setzt verschiedene Umgebungsvariablen, die für die
    korrekte Funktion von httpd unter einigen
    Betriebssystemen notwendig sind, und startet dann das
    httpd-Programm. apachectl
    reicht alle Kommandozeilenargumente durch, so dass alle
    httpd-Optionen auch mit apachectl
    verwendet werden können. Um den korrekten Ablageort des
    httpd-Programms sowie einige Kommandozeilenargumente
    anzugeben, die Sie immer verwenden möchten, können
    Sie auch das Skript apachectl direkt editieren und die
    Variable HTTPD am Anfang ändern.
    

    
    Das Erste was httpd macht, wenn es startet, ist das
    Suchen und Einlesen der Konfigurationsdatei httpd.conf.
    Der Ablageort dieser Datei wird zur Kompilierungszeit festgelegt. Es ist
    aber möglich, den Ablageort zur Laufzeit anzugeben, indem die
    Kommandozeilenoption -f wie folgt verwendet wird:
    

    
    /usr/local/apache2/bin/apachectl -f

    Wenn während des Starts alles gutgeht, trennt sich der Server
    vom Terminal ab und die Eingabeaufforderung erscheint gleich darauf
    wieder. Dies zeigt an, dass der Server hochgefahren ist und läuft.
    Sie können nun Ihren Browser benutzen, um Verbindung zum Server
    aufzunehmen und sich die Testseite im DocumentRoot-Verzeichnis anzusehen wie auch
    die lokale Kopie der Dokumentation, die von dieser Seite aus verlinkt
    ist.

    Fehler während des Hochfahrens
    

    
    Wenn der Apache während des Hochfahrens einen schweren Fehler
    feststellt, schreibt er entweder eine Nachricht, die das Problem
    näher schildert, auf die Konsole oder ins ErrorLog, bevor er sich selbst beendet.
    Eine der häufigsten Fehlermeldungen ist "Unable
    to bind to Port ..." (Anm.d.Ü.: "Kann nicht an Port ...
    binden"). Diese Meldung wird üblicherweise verursacht:
    

    
      
      
    • entweder durch den Versuch, den Server an einem privilegierten
      Port zu starten, während man nicht als Benutzer root angemeldet
      ist,
      • 

      
    • oder durch den Versuch, den Server zu starten, wenn bereits eine
      andere Instanz des Apache oder ein anderer Webserver an den gleichen
      Port gebunden ist.
      • 
    
    

    
    Für weitere Anleitungen zur Fehlerbehebung lesen Sie bitte die
    Apache-FAQ.

    Beim Bootvorgang starten
    

    
    Wenn Sie möchten, dass Ihr Server direkt nach einem
    System-Neustart weiterläuft, sollten Sie einen Aufruf von
    apachectl zu den Startdateien Ihres Systems
    hinzufügen (üblicherweise rc.local oder
    eine Datei in einem rc.N-Verzeichnis). Dies startet
    den Apache als root. Stellen Sie zuvor jedoch sicher, dass Ihr
    Server hinsichtlich Sicherheit und Zugriffsbeschränkungen
    richtig konfiguriert ist.
    

    
    Das apachectl-Skript ist dafür ausgelegt, wie
    ein Standard-SysV-init-Skript zu arbeiten. Es akzeptiert die Argumente
    start, restart und stop
    und übersetzt sie in die entsprechenden Signale für
    httpd. Daher können Sie oftmals
    einfach apachectl in das entsprechende init-Verzeichnis
    linken. Überprüfen Sie bitte auf jeden Fall die genauen
    Anforderungen Ihres Systems.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    
    本文書の内容は次の一言に尽きます。「Apache が設定ファイルを読み込むときに
    DNS を使用する必要がないようにして下さい」。Apache が設定ファイルを
    読み込むときに DNS を使用する必要がある場合、信頼性の問題
    (起動しないかもしれません) やサービス拒否や盗用アタック
    (他のユーザからヒットを盗むことを含みます)
    の問題に直面するかもしれません。
    
  
    


    top
    

    

    簡単な例
    
    

    
    
      <VirtualHost www.abc.dom> 
    
      ServerAdmin webgirl@abc.dom 
    
      DocumentRoot /www/abc 
    
      </VirtualHost>
    
    

    
    Apache が正常に機能するには、バーチャルホスト毎に必ず二つの
    情報が必要になります。それは、
    ServerName
    と、そのサーバが応答するための IP (最低一つ) です。
    上記例では IP アドレスを含んでいませんので、Apache は DNS
    を使用して www.abc.dom を見つけなければなりません。
    何らかの理由で設定ファイルを読み込んでいるときに DNS 
    が利用できなかった場合、
    バーチャルホストは設定されません。
    そして、そのバーチャルホストに対するヒットには応答がなされません
    (Apache 1.2 以前では起動すらしません)。
    

    
    www.abc.dom のアドレスが 192.0.2.1
    だとします。では、次の設定について考えてみましょう。
    

    
    
      <VirtualHost 192.0.2.1> 
    
      ServerAdmin webgirl@abc.dom 
    
      DocumentRoot /www/abc 
    
      </VirtualHost>
    
    

    
    現在のリリースでは Apache は DNS 逆引きを使用して
    このバーチャルホストの ServerName
    を見つけます。
    その逆引きが失敗した場合は部分的にバーチャルホストを無効にします
    (Apache 1.2 より前では起動すらしません)。
    バーチャルホストが名前ベースであれば完全に無効になりますが、
    IP ベースであれば概ね動作します。しかしながら、サーバ名を
    含む完全な URL を生成しなければならない場合は、正しい URL
    の生成ができません。
    

    
    次の例は上記の問題を解決しています。
    

    
    
      <VirtualHost 192.0.2.1> 
    
      ServerName www.abc.dom 
    
      ServerAdmin webgirl@abc.dom 
    
      DocumentRoot /www/abc 
    
      </VirtualHost>
    
    
  
    top
    

    

    サービス拒否
    
    

    
    サービス拒否が起こる場合、(少なくとも) 二つのケースがあります。
    Apache 1.2 より前を実行している場合、バーチャルホストのための
    上記の二つの DNS 検索のうち一つ失敗すれば起動すらしません。
    そしてこの DNS 検索が自分の制御下にすらない場合もありえます。
    例えば、abc.dom が顧客のサーバの一つで、
    DNS は顧客自身で管理している場合、単に
    www.abc.dom レコードを削除するだけで、
    (1.2 より前の) サーバを起動不能にすることができます。
    

    
    もう一つのケースは、より気付きにくいものです。
    次の設定について考えてみましょう。
    

    
    
      <VirtualHost www.abc.dom> 
    
      
        ServerAdmin webgirl@abc.dom 
    
        DocumentRoot /www/abc 
    
          
      </VirtualHost> 
    
      
    
      <VirtualHost www.def.dom> 
    
      
        ServerAdmin webguy@def.dom 
    
        DocumentRoot /www/def 
    
          
      </VirtualHost>
    
    

    
    192.0.2.1 を www.abc.dom に、
    192.0.2.2 を www.def.dom に割り当てているとします。
    また、def.dom は顧客自身の DNS
    の制御下にあるとします。この設定で、abc.dom
    に向けられたトラフィック全てを奪うことができる位置に
    def.dom を設置できています。後は単に 
    www.def.dom が 192.0.2.1 を参照するように
    設定するだけです。DNS は顧客側の DNS でコントロールされているので、
    www.def.dom レコードが好きな場所を指すように
    設定できてしまうのを止めさせることができません。
    

    
    192.0.2.1 に対するリクエスト
    (http://www.abc.dom/whatever 形式の URL 
    を入力したユーザからのもの全てを含みます) 
    は、def.dom バーチャルホストで応答されます。
    このようなことが何故起こるかもっと良く知るためには、
    応答の必要なバーチャルホストへのリクエストに対して、
    Apache がどのように整合性を確保するかについて、
    深い議論が必要になります。おおざっぱな説明はこちらに記述されています。
    
  
    top
    

    

    「主サーバ」アドレス
    
    

    
    Apache 1.1 での 名前ベースのバーチャルホストのサポート 追加の際に、
    Apache は httpd の実行されているホストの IP
    アドレスを知る必要が出てきました。このアドレスを得るために、
    (もしあれば) グローバルな
    ServerName を使用するか、
    C 言語の関数 gethostname (コマンドプロンプトで
    hostname とタイプしたときと同じものを返します)
    を呼び出すかをします。
    その後、得られたアドレスで DNS 検索を行ないます。
    現在のところ、この DNS 検索を回避する方法はありません。
    

    
    DNS サーバがダウンして、この検索ができない事態が起こることを
    恐れているのであれば、/etc/hosts
    にホスト名を記述しておくことができます
    (マシンが正常に起動するように既に設定されているかもしれません)。
    その場合、DNS 参照が失敗した場合にマシンが /etc/hosts
    を使用するように設定していることを確認してください。
    その方法は、どの OS を使用しているかに依存しますが、
    /etc/resolv.conf か /etc/nsswitch.conf
    を編集することで設定できます。
    

    
    もし他の理由で DNS を利用する必要がない場合は、
    HOSTRESORDER 環境変数を「 local
    」に設定することでそのようにできます。以上これらの事柄は、どんな
    OS 、レゾルバライブラリを使用しているかに依存します。また、
    mod_env を使用して環境変数を制御しない限り、
    CGI にも影響を与えます。man ページや使用している OS
    の FAQ で調べると良いでしょう。
    
  
    top
    

    

    以上の問題を解決する方法
    
    

    
      
      
    • 
        VirtualHost
        で IP アドレスを使用する。
      
      • 

      
    • 
        Listen
        で IP アドレスを使用する。
      
      • 

      
    • 
        全てのバーチャルホストが明示的に
        ServerName
        を持つようにする。
      
      • 

      
    • 何も応答しない
      <VirtualHost _default_:*>
      サーバを作る。
      • 
    
    
  
    top
    

    

    付録: 将来的な方向性
    
    

    
    DNS に関して、現状は全く宜しくありません。Apache 1.2 で、
    DNS のイベントが失敗しても少なくとも起動プロセスが続くようにしましたが、
    これが最高の解決方法ではないでしょう。アドレスの再割り当てが必要不可避
    となっている今日のインターネットにおいては、
    設定ファイルの中で明示的な IP アドレスを要求する仕様は、
    全く宜しくありません。
    

    
    盗用のサービスアタックに関して行なうべき事は、
    DNS 順引きを行なって得られたアドレスに対する DNS 
    逆引きを行なって、二つの名前を比較することです。
    この二つが一致しなければバーチャルホストは無効になるようにします。
    こうするためには逆引き DNS が適切に設定されている必要があります
    (FTP サーバや TCP ラッパーのおかげで「二重逆引き」DNS は一般的に
    なっていますので、管理者にはお馴染みものでしょう)。
    

    
    IP アドレスが使用されていなくて DNS が失敗した場合は、
    どうしてもバーチャルホストウェブサーバを信頼性を確保して
    起動させることは不可能のようです。
    設定の一部を無効にするというような部分的な解決では、
    サーバが何をするようにするかにもよりますが、
    そのサーバが起動しないより確実に悪い状況になるでしょう。
    

    
    HTTP/1.1 が開発され、ブラウザやプロキシが Host
    ヘッダを発行するようになったので、IP ベースのバーチャルホストを
    全く使用しなくても済むようになるかもしれません。
    この場合、ウェブサーバは設定中に DNS 参照をしなくても済みます。
    しかし 1997 年 3 月時点の状況では、
    商用レベルのウェブサーバで使用できるほどには、
    これらの機能は広く開発が進んでいません。

    Apache et les variables d'environnement
    

    

    Langues Disponibles:  en  |

 tr 
    

    

     
    Deux types de variables d'environnement affectent le serveur
     HTTP Apache.
    

    
    Le premier type correspond aux variables d'environnement
    contrôlées par le système d'exploitation sous-jacent et définies
    avant le démarrage du serveur. Leurs valeurs peuvent être utilisées
    directement dans les fichiers de configuration, et peuvent
    éventuellement être transmises aux scripts CGI et SSI via la
    directive PassEnv.
    

    
    Le second type correspond aux variables nommées appelées aussi
    variables d'environnement dans lesquelles le serveur HTTP
    Apache stocke des informations via un mécanisme spécial. Ces
    informations peuvent servir à contrôler diverses opérations comme
    l'enregistrement des traces ou le contrôle d'accès. On utilise aussi ces
    variables dans le mécanisme de communication avec les programmes externes
    comme les scripts CGI. Ce document présente différentes méthodes pour
    manipuler et utiliser ces variables.
    

    
    Bien que ces variables soient référencées comme variables
    d'environnement, il ne faut pas les confondre avec les variables
    d'environnement contrôlées par le système d'exploitation sous-jacent.
    En fait, ces variables sont stockées et manipulées dans une structure
    interne à Apache. Elles ne deviennent de véritables variables
    d'environnement du système d'exploitation que lorsqu'elles sont mises à la
    disposition de scripts CGI et de scripts inclus côté serveur (SSI). Si vous
    souhaitez manipuler l'environnement du système d'exploitation sous lequel
    le serveur s'exécute, vous devez utiliser les mécanismes standards de
    manipulation de l'environnement fournis par l'interpréteur de commandes
    (shell) de votre système d'exploitation.

    Définition des variables d'environnement
    
    
    
    Modules ApparentésDirectives Apparentées
    

    
    Manipulations de base de l'environnement
    
        

        
    La méthode la plus élémentaire pour définir une variable
	d'environnement au niveau d'Apache consiste à utiliser la directive
	inconditionnelle SetEnv. Les variables peuvent aussi être transmises depuis
	l'environnement du shell à partir duquel le serveur a été démarré en
	utilisant la directive
        PassEnv.
    

    
    
    Définitions conditionnelles en fonction des requêtes
    
        

        
    Pour plus de souplesse, les directives fournies par le module
        mod_setenvif permettent de définir les
	variables d'environnement en tenant compte des caractéristiques
	de chaque requête. Par exemple, une
	variable pourrait n'être définie que lorsqu'un navigateur spécifique
	(User-Agent) a généré la requête, ou seulement quand un en-tête
	Referer particulier est présent. La directive
	RewriteRule du module
	mod_rewrite qui utilise l'option
	[E=...] pour définir
	les variables d'environnement apporte encore plus de souplesse.
    

    
    
    Identifiants uniques
    
        

        
    Finalement, le module mod_unique_id définit la variable
	d'environnement UNIQUE_ID pour chaque requête à une valeur
	qui est garantie unique parmi "toutes" les requêtes sous des
	conditions très spécifiques.
    

    
    
    Variables CGI standards
    
        

        
    En plus de l'ensemble des variables d'environnement internes à la
	configuration d'Apache et de celles transmises depuis le shell,
	les scripts CGI	et les pages SSI
	se voient affectés un ensemble de variables
	d'environnement contenant des méta-informations à propos de la requête
	comme préconisé dans la
	spécification
	sur les CGIs.
    

    
    
    Quelques mises en garde
    
        

        
      
          
    • Les directives de manipulation de l'environnement ne permettent
	  pas de supplanter ou modifier les variables CGI standards.
      • 

          
    • Lorsqu'on utilise suexec pour exécuter des
	  scripts CGI, l'environnement est nettoyé et réduit à un ensemble de
	  variables sûres avant l'exécution du script. La liste des
	  variables sûres est définie à la compilation dans
          suexec.c.
      • 

          
    • Pour des raisons de portabilité, les noms des variables
	  d'environnement ne peuvent contenir que des lettres, des chiffres, et
	  le caractère "sousligné". En outre, le premier caractère ne doit pas
	  être un chiffre. Les caractères qui ne satisfont pas à ces conditions
	  seront remplacés par un caractère "sousligné" quand ils seront
	  transmis aux scripts CGI et aux pages SSI.
      • 

	  
    • Les contenus d'en-têtes HTTP transmis aux scripts de type
	  CGI ou autre via des variables d'environnement constituent un
	  cas particulier (voir plus loin). Leur nom est converti en
	  majuscules et seuls les tirets sont remplacés par des
	  caractères '_' ("souligné") ; si le format du nom de l'en-tête
	  n'est pas valide, celui-ci est ignoré. Voir plus loin pour une solution de
	  contournement du problème.
      • 

          
    • La directive SetEnv s'exécute assez tard au
	  cours du traitement de la requête, ce qui signifie que des
	  directives telles que SetEnvIf et RewriteCond ne verront pas
	  les variables qu'elle aura définies.
      • 

	  
    • Lorsque le serveur cherche un chemin via une sous-requête interne (par exemple la
   recherche d'un DirectoryIndex), ou lorsqu'il génère un
   listing du contenu d'un répertoire via le module
   mod_autoindex, la sous-requête n'hérite pas des
   variables d'environnement spécifiques à la requête. En outre, à cause
   des phases de l'API auxquelles mod_setenvif prend
   part, les directives SetEnvIf ne sont pas évaluées
   séparément dans la sous-requête.
      •

    Utilisation des variables d'environnement
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Scripts CGI
    
        

        
    La communication d'informations aux scripts CGI constitue une des
	principales utilisations des variables d'environnement. Comme indiqué
	plus haut, l'environnement transmis aux scripts CGI comprend des
	méta-informations standards à propos de la requête, en plus des
	variables définies dans la configuration d'Apache. Pour plus de
	détails, se référer au
        tutoriel CGI.
    

    
    
    Pages SSI
    
        

        
    Les documents inclus côté serveur (SSI) traités par le filtre
        INCLUDES du module mod_include,
	peuvent afficher les
	variables d'environnement à l'aide de l'élément echo,
	et peuvent utiliser des variables d'environnement dans les éléments
	de contrôle de flux pour rendre certaines parties d'une page
        conditionnelles en fonction des caractéristiques de la requête.
	Apache fournit aussi les variables d'environnement CGI standards
	aux pages SSI
	comme indiqué plus haut. Pour plus de détails, se référer au
	tutoriel SSI.
    

    
    
    Contrôle d'accès
    
        

        
    L'accès au serveur peut être contrôlé en fonction de la valeur de
	variables d'environnement à l'aide des directives
	Require env et Require not env.
	En association avec la directive
        SetEnvIf, ceci confère une
	grande souplesse au contrôle d'accès au serveur en fonction des
	caractéristiques du client. Par exemple, vous pouvez utiliser ces
        directives pour interdire l'accès depuis un navigateur particulier
	(User-Agent).
        
    

    
    
    Enregistrement conditionnel des traces
    
        

        
    Les variables d'environnement peuvent être enregistrées dans le
	fichier de log des accès à l'aide de l'option %e de la
	directive LogFormat.
	En outre, la décision de tracer ou non les requêtes peut être prise
	en fonction de l'état de variables d'environnement en utilisant la
	forme conditionnelle de la directive
        CustomLog. En
	association avec la directive SetEnvIf, ceci confère une grande souplesse au contrôle
	du traçage des requêtes. Par exemple, vous pouvez choisir de ne pas
	tracer les requêtes pour des noms de fichiers se terminant par
	gif, ou encore de ne tracer que les requêtes des clients
	n'appartenant pas à votre sous-réseau.
    

    
    
    En-têtes de réponse conditionnels
    
        

        
    La directive Header
        peut se baser sur la présence ou l'absence d'une variable
	d'environnement pour décider si un certain en-tête HTTP sera placé
	dans la réponse au client. Ceci permet, par exemple, de n'envoyer un
	certain en-tête de réponse que si un en-tête correspondant est présent
	dans la requête du client.
    

    

    
    Activation de filtres externes
    
        

        
    Les filtres externes configurés par le module
	mod_ext_filter à l'aide de la directive ExtFilterDefine peuvent être
	activés de manière conditionnelle en fonction d'une variable

    La forme %{ENV:variable} de

        Notez que les variables accessibles dans

        ENV: ne sont pas de véritables variables

        qui ne sont pas accessibles pour les autres modules.

    Variables d'environnement à usage spécial
    
    

        
    Des problèmes d'interopérabilité ont conduit à l'introduction de
	mécanismes permettant de modifier le comportement d'Apache lorsqu'il
	dialogue avec certains clients. Afin de rendre ces mécanismes aussi
	souples que possible, ils sont invoqués en définissant des variables
	d'environnement, en général à l'aide de la directive
	BrowserMatch, bien que les
	directives SetEnv et
	PassEnv puissent aussi être
	utilisées, par exemple.
    

    
    downgrade-1.0
    
        

        
    Ceci force le traitement d'une requête comme une requête HTTP/1.0
        même si elle a été rédigée dans un langage plus récent.
    

    
    
    force-gzip
    
        
          
    Si le filtre DEFLATE est activé, cette variable
	  d'environnement ignorera les réglages accept-encoding de votre
	  navigateur et enverra une sortie compressée inconditionnellement.
    
    
    
    force-no-vary
    
        

        
    Cette variable entraîne la suppression de tout champ
	Vary des en-têtes de la réponse avant que cette dernière
	soit renvoyée au client. Certains clients n'interprètent pas ce champ
	correctement, et la définition de cette variable permet de contourner
	ce problème, mais implique aussi la définition de
	force-response-1.0.
    

    
    
    force-response-1.0
    
        

      
    Cette variable force une réponse en langage HTTP/1.0 aux clients
      qui envoient des requêtes dans le même langage. Elle fut implémentée à
      l'origine suite à des problèmes avec les mandataires d'AOL. Certains
      clients en langage HTTP/1.0 ne réagissent pas correctement face à une
      réponse en langage HTTP/1.1, et cette variable peut être utilisée pour
      assurer l'interopérabilité avec eux.
    

    

    
    gzip-only-text/html
    
        

        
    Positionnée à "1", cette variable désactive le filtre en sortie
	DEFLATE fourni par le module mod_deflate pour les
	types de contenu autres que text/html. Si vous préférez
	utiliser des fichiers compressés statiquement,
	mod_negotiation évalue aussi la variable (non
	seulement pour gzip, mais aussi pour tous les encodages autres que
	"identity").
    
    

    
    no-gzip
    

        
    Quand cette variable est définie, le filtre DEFLATE du
	module mod_deflate est désactivé, et
        mod_negotiation refusera de délivrer des ressources
	encodées.
    

    

    
    no-cache
    
    	
    Disponible dans les versions 2.2.12 et ultérieures d'Apache
    

        
    Lorsque cette variable est définie,
	mod_cache ne sauvegardera pas de réponse
	susceptible d'être mise en cache. Cette variable d'environnement
	n'a aucune incidence sur le fait qu'une réponse déjà enregistrée
	dans la cache soit utilisée ou non pour la requête courante.
    

    

    
    nokeepalive
    
        

        
    Quand cette variable est définie, la directive
	KeepAlive est désactivée.
    

    

    
    prefer-language
    

        
    Cette variable modifie le comportement du module
	mod_negotiation. Si elle contient un symbole de
	langage (tel que en, ja
        ou x-klingon), mod_negotiation essaie de
	délivrer une variante dans ce langage. S'il n'existe pas de telle
	variante, le processus normal de
	négociation s'applique.
    

    

    
    redirect-carefully
    
        

        
    Cette variable force le serveur à être plus prudent lors de l'envoi
	d'une redirection au client. Elle est en général utilisée quand un
	client présente un problème connu avec les redirections. Elle fut
	implémentée à l'origine suite a un problème rencontré avec le logiciel
	WebFolders de Microsoft qui ne gère pas correctement les redirections
	vers des ressources de type répertoire via des méthodes DAV.
    

    

   
    suppress-error-charset
    
       

    
    Disponible dans les versions postérieures à 2.0.54
    

    
    Quand Apache génère une redirection en réponse à une requête client,
    la réponse inclut un texte destiné à être affiché au cas où le client ne
    suivrait pas, ou ne pourrait pas suivre automatiquement la redirection.
    Habituellement, Apache marque ce texte en accord avec le jeu de caractères
    qu'il utilise, à savoir ISO-8859-1.
    
    
     Cependant, si la redirection fait référence à une page qui utilise un
    jeu de caractères différent, certaines versions de navigateurs obsolètes
    essaieront d'utiliser le jeu de caractères du texte de la redirection
    plutôt que celui de la page réelle.
    Ceci peut entraîner, par exemple, un rendu incorrect du Grec.
    
    
    Si cette variable d'environnement est définie, Apache omettra le jeu de
    caractères pour le texte de la redirection, et les navigateurs obsolètes
    précités utiliseront correctement celui de la page de destination.
    

    
    
      
    Note concernant la sécurité
    

      
    L'envoi de pages d'erreur sans spécifier un jeu de caractères peut
      conduire à des attaques de type "cross-site-scripting" pour les
      navigateurs qui ne respectent pas la spécification HTTP/1.1 (MSIE) et
      tentent de déduire le jeu de caractères à partir du contenu. De tels
      navigateurs peuvent être facilement trompés et utiliser le jeu de
      caractères UTF-7 ; les contenus des données en entrée de type UTF-7
      (comme les URI de requête) ne seront alors plus protégés par les
      mécanismes d'échappement usuels conçus pour prévenir les attaques
      de type "cross-site-scripting".
    
    
    

   

   
    force-proxy-request-1.0, proxy-nokeepalive, proxy-sendchunked,
   proxy-sendcl, proxy-chain-auth, proxy-interim-response, proxy-initial-not-pooled
    

   
    Ces directives modifient le comportement protocolaire du module
   mod_proxy.  Voir la documentation sur
   mod_proxy et mod_proxy_http pour plus de détails.
    
   

  
    top
    

    

    Exemples
    
    

    
    Transmission du contenu d'en-têtes non valides aux scripts
      CGI
    
      

      
    Avec la version 2.4, Apache est plus strict avec la conversion
      des en-têtes HTTP en variables d'environnement dans
      mod_cgi et d'autres modules : dans les versions
      précédentes, tout caractère invalide dans les noms d'en-têtes
      était tout simplement remplacé par un caractère '_', ce qui
      pouvait exposer à des attaques de type cross-site-scripting via
      injection d'en-têtes (voir Bogues
      du Web inhabituelles, planche 19/20).
    

      
    Si vous devez supporter un client qui envoie des en-têtes non
      conformes et si ceux-ci ne peuvent pas être corrigés, il existe
      une solution de contournement simple mettant en jeu les modules
      mod_setenvif et mod_headers,
      et permettant de prendre en compte ces en-têtes :
    


    # L'exemple suivant montre comment prendre en compte un en-tête
    
# Accept_Encoding non conforme envoyé par un client.
#
SetEnvIfNoCase ^Accept.Encoding$ ^(.*)$ fix_accept_encoding=$1
RequestHeader set Accept-Encoding %{fix_accept_encoding}e env=fix_accept_encoding
    


    

    
    Modification du comportement protocolaire face à des clients
	réagissant de manière non conforme
    
        

        
    Les versions antérieures recommandaient l'ajout de ces lignes dans
        httpd.conf pour tenir compte de problèmes connus avec certains clients.
	Comme les clients concernés sont maintenant très peu utilisés, cet
	ajout n'est pratiquement plus nécessaire.
    

    #
# The following directives modify normal HTTP response behavior.
# The first directive disables keepalive for Netscape 2.x and browsers that
# spoof it. There are known problems with these browser implementations.
# The second directive is for Microsoft Internet Explorer 4.0b2
# which has a broken HTTP/1.1 implementation and does not properly
# support keepalive when it is used on 301 or 302 (redirect) responses.
#
BrowserMatch "Mozilla/2" nokeepalive
BrowserMatch "MSIE 4\.0b2;" nokeepalive downgrade-1.0 force-response-1.0

#
# The following directive disables HTTP/1.1 responses to browsers which
# are in violation of the HTTP/1.0 spec by not being able to grok a
# basic 1.1 response.

BrowserMatch "RealPlayer 4\.0" force-response-1.0
BrowserMatch "Java/1\.0" force-response-1.0
BrowserMatch "JDK/1\.0" force-response-1.0

    Cet exemple montre comment empêcher les utilisateurs ne faisant pas
	partie de votre serveur d'utiliser des images de votre serveur comme
	images en ligne dans leurs pages. Cette configuration n'est pas
	recommandée, mais elle peut fonctionner dans des circonstances bien
	définies. Nous supposons que toutes vos images sont enregistrées dans
	un répertoire nommé /web/images.

    Giriş
    

    
    Apache HTTP Sunucusunu durdurmak ve yeniden başlatmak için çalışan
      httpd süreçlerine bir sinyal göndermeniz gerekir.
      Sinyal göndermek için iki yol vardır. İlki, süreçlere doğrudan sinyal
      göndermek için unix kill komutunun kullanımıdır. Bu
      suretle, sisteminizde çalışmakta olan bir çok httpd
      sürecini uyarabilirsiniz ama süreç kimliği PidFile yönergesi ile belirtilen dosyada
      tutulan ana süreç dışında hiçbirine sinyal göndermemelisiniz. Başka
      bir deyişle, ana süreç haricinde hiçbir sürece sinyal göndermeye normal
      olarak ihtiyacınız olmaması gerekir. Ana sürece gönderebileceğiniz
      dört çeşit sinyal vardır:
      TERM,
      USR1,
      HUP ve
      WINCH. Bunlar yeri geldikçe
      açıklanacaktır.
    

    
    Ana sürece kill ile sinyal göndermek için şöyle bir
      komut verebilirsiniz:
    

    
    kill -TERM `cat /usr/local/apache2/logs/httpd.pid`
    

    
    httpd süreçlerine sinyal göndermenin ikinci yolu
      -k komut satırı seçeneğini şu değerlerden biri ile
      kullanmaktır: stop, restart,
      graceful ve graceful-stop. Bunlar aşağıda
      açıklanacaktır. -k komut satırı seçeneği
      httpd’ye ait olsa da ana sürece bu sinyalleri
      göndermek için apachectl betiğini kullanmanızı
      öneririz. apachectl, komut satırı seçeneklerini
      httpd’ye aktaracaktır.
    

    
    httpd’ye sinyal gönderdikten sonra olup biteni şu
      komutla izleyebilirsiniz:
    

    
    tail -f /usr/local/apache2/logs/error_log
    

    
    Bu örnekleri, kendi ServerRoot ve
      PidFile yönergelerinizdeki
      ayarlara uygun olarak değiştirdikten sonra kullanınız.
    

    top
    

    

    Hemen Durdur
    

  
    Sinyal: TERM
    
    
    apachectl -k stop
    
  
    

    
    Ana sürece TERM veya stop sinyali
      göndererek tüm çocukların bir an önce öldürülmeye çalışılmasını sağlamış
      olursunuz. Tüm çocukların öldürülmesi bir kaç saniye sürebilir. Son
      olarak ana süreç çıkacaktır. Yanıtlanmakta olan istekler hemen
      sonlandırılacak ve artık isteklere yanıt verilmeyecektir.
    

    top
    

    

    Nazikçe Yeniden Başlat
    

  
    Sinyal: USR1
    
    
    apachectl -k graceful
    
  
    

    
    Ana sürece USR1 veya graceful sinyalinin
      gönderilmesi, çocuklara ellerindeki mevcut işleri bitirdikten sonra
      (veya sundukları bir şey yoksa hemen) çıkmalarının önerilmesi
      demektir. Ana süreç kendi yapılandırma dosyalarını yeniden okur ve
      kendi günlük dosyalarını yeniden açar. Ana sürecin öldürdüğü her sürecin
      yerine yeni yapılandırma kuşağından bir süreç başlatır ve hemen
      yeni isteklere hizmet sunulmaya başlanır.
    

    
    Bu kod MPM’lerin süreçleri denetleyen yönergelerine daima uyacak
      şekilde tasarlanmıştır. Bu suretle, istemcilere hizmet sunacak çocuk
      süreçler ve evreler, yeniden başlatma işleminde de uygun sayıda
      sağlanmış olur. Bununla birlikte, StartServers yönergesinde şöyle
      davranılır: İlk saniye içinde en azından StartServers sayıda yeni çocuk
      oluşturulmamışsa iş olmayan bir devreyi geçiştirecek kadarı oluşturulur.
      Ardından sunucunun mevcut yükünü karşılamak için gereken sayıda çocuk
      süreç oluşturulur. Bu suretle, kod her ikisi için de gereğini yerine
      getirmeye çalışmış olur.
    

    
    mod_status kullanıcıları USR1
      gönderildiği zaman sunucu istatistiklerinin sıfırlanmadığı konusunda
      uyarılacaktır. Kod, sunucunun yeni isteklere yanıt veremediği zamanı en
      aza indirmenin yanısıra ayar parametrelerinize de uymak üzere
      tasarlanmıştır (yeni istekler işletim sistemi tarafından kuyruğa
      alınacağından bir istek kaybı olayı yaşanmaz). Bunu sağlamak için, her
      iki kuşağın çocuklarının izini sürecek bir çetele tutulur.
    

    
    mod_status modülü, nazikçe yeniden başlat komutunun
      verilmesinden önce başlamış ve sunulmaya devam eden isteklere bakan
      çocukları imlemek için ayrıca bir G (Graceful’un baş harfi)
      kullanır.
    

    
    Günlük dosyası döndürme betiğine, yeniden başlatma öncesi günlüğe yazan
      tüm çocukların işini bitirdiğini USR1 kullanarak
      bildirmenin bir yolu yoktur.  Önerimiz, eski günlük kaydı üzerinde bir
      işlem yapmaya başlamadan önce USR1 sinyali gönderilmesinin
      ardından belli bir süre beklenilmesi olacaktır. Örneğin, düşük band
      genişliğine sahip istemcilere hizmet sunan çoğu sürecin işinin 10
      dakikadan önce bitmeyeceğini gözönüne alarak eski günlük üzerinde işlem
      yapmaya başlamak için 15 dakika beklenebilir.
    

    
    
    
    Bir yeniden başlatma isteğinde, yapılandırma dosyalarında bir hata
      olmadığından emin olmak için önce bir sözdizimi denetimi yapılır. Eğer
      yapılandırma dosyalarınızda bir hata varsa bu sözdizimi hatasıyla ilgili
      bir hata iletisi alırsınız ve sunucu yeniden başlamayı reddeder. Bu
      yolla, bir hata sonucu sunucunun çökerek yeniden başlamaması nedeniyle
      işlevsiz bir sunucuyla başbaşa kalmanız önlenmiştir.
    

    
    Ancak, bu hala sunucunuzun düzgünce yeniden başlatılmasını garanti
      etmeyecektir. Yapılandırma dosyalarınızı sözdizimi denetiminin yanında
      anlamlandırılması bakımından da sınamak için
      httpd’nin root olmayan bir kullanıcı tarafından
      çalıştırılmasını deneyebilirsiniz. Eğer yapılandırma dosyalarında bir
      hata yoksa soketleri ve günlük dosyalarını açmaya çalışırken root
      aidiyetinde çalışmadığından veya çalışmakta olan asıl sunucu bu portları
      zaten dinlediğinden başarısız olacaktır. Eğer başka bir sebeple
      başarısız olursa olası sebep bir yapılandırma dosyası hatasıdır ve asıl
      sunucuya ‘nazikçe yeniden başla’ komutunu vermeden önce bu hatayı
      düzeltmeniz gerekir.
    

    top
    

    

    Hemen Yeniden Başlat
    

  
    Sinyal: HUP
    
    
    apachectl -k restart
    
  
    

    
    Ana sürece HUP veya restart sinyalinin
      gönderilmesi tüm çocukların TERM sinyali gönderilmiş gibi
      öldürülmesine sebep olur fakat ana sürecin çıkmasını sağlamaz.
      Ana süreç yapılandırma dosyalarını yeniden okur ve günlük kayıt
      dosyalarını yeniden açar. Bunların ardından isteklere yanıt verecek yeni
      kuşak çocukları oluşturmaya başlar.
    

    
    mod_status kullanıcıları bir HUP sinyalı
      gönderildiğinde sunucu istatistiklerinin sıfırlandığı konusunda
      uyarılırlar.
    

    
    ‘Nazikçe yeniden başlat’ komutundaki gibi yeniden başlatma öncesi
      bir sözdizimi denetimi yapılır. Eğer yapılandırma dosyalarınızda
      sözdizimi hatası varsa yeniden başlatma işlemi gerçekleşmez ve sözdizimi
      hatalarıyla ilgili bildirim alırsınız.
    

    top
    

    

    Nazikçe Durdur
    

  
    Sinyal: WINCH
    
    
    apachectl -k graceful-stop
    
  
    

    
    Ana sürecin WINCH veya graceful-stop
      sinyalini alması, çocuklara ellerindeki mevcut işleri bitirdikten sonra
      (veya sundukları bir şey yoksa hemen) çıkmalarının önerilmesine
      sebep olur. Ana süreç bunun hemen ardından PidFile dosyasını siler ve port
      dinlemeyi keser. Ana süreç  çalışmaya ve isteklere yanıt vermekte olan
      çocuk süreçleri izlemeye devam eder. Tüm çocuklar işlerini bitirip
      çıktığında veya GracefulShutdownTimeout ile belirtilen
      zaman aşımı dolduğunda ana süreç de kendini sonlandırır. Eğer zaman aşımı
      devreye girmişse o an çalışmakta olan çocuk süreçlere TERM
      sinyali gönderilerek hemen çıkmaları sağlanır.
    

    
    Bir TERM sinyali ile "graceful" durumundaki tüm çocuklar
      ve ana süreç hemen sonlandırılacaktır. Bununla birlikte, PidFile dosyası da silineceğinden, artık
      apachectl veya httpd’yi bu sinyali göndermek
      için kullanamayacaksınız.
    

    
    graceful-stop sinyali, aynı anda, aynı yapılandırma
      ile çok sayıda httpd kopyasının çalıştırılabilmesine
      imkan verir.  Bu, Apache nazikçe yükseltileceği zaman güçlü bir özellik
      haline gelmekteyse de, bazı yapılandırmalarda yarış koşullarının
      oluşmasına ve kısır çekişmelere (deadlock) sebep olabilir.
    

    
    Sunucunun süreç kimliğini içeren kilit dosyaları (Mutex) ve Unix soket dosyaları
      (ScriptSock) gibi dosyaların
      disk üzerindeki mevcudiyetlerinin sorunsuz olarak devam ettiğinden emin
      olunmaya çalışılmalıdır.  Ayrıca, bir yapılandırma yönergesi, üçüncü
      parti bir modül veya kalıcı CGI uygulamalarına ait disk kilit veya durum
      dosyaları olabilir; httpd’nin birden fazla kopyasının
      çalışması nedeniyle bu dosyaların da üzerine yazılmadığından emin
      olunmaya çalışılmalıdır.
    

    
    rotatelogs tarzı borulu günlükleme kullanımı gibi
      durumlarda yarış koşullarının oluşması olasılığına karşı uyanık
      olunmalıdır. Aynı günlük kayıt dosyalarını aynı anda döndürmeye çalışan
      birden fazla rotatelogs kopyasının çalıştırılması
      halinde bunların her biri diğerlerinin günlük kayıt dosyalarının kaybına
      sebep olabilir.

    Apache HTTPD, içerik uzlaşımını HTTP/1.1 belirtiminde bahsedildiği şekliyle
      destekler. Bir özkaynağın en iyi gösterimini, tarayıcının sağladığı
      karakter kodlaması, karakter kümesi, dil, ortam türü gibi kullanıcı
      tercihlerine bağlı olarak seçebilir. Ayrıca, tarayıcının kullanıcı
      tercihlerini tam yansıtamadığı durumlarda istekleri daha akıllıca ele
      alabilmeyi sağlayacak bir takım özelliklere de sahiptir.
    

    
    İçerik uzlaşımı öntanımlı olarak derlenen
      mod_negotiation modülü tarafından sağlanır.

    İçerik Uzlaşımı Hakkında
    

    
    Bir özkaynağın bir çok farklı gösterimi olabilir. Örneğin, bir belgenin
      farklı ortam türleri ve/veya farklı diller için gösterimleri olabilir.
      En uygun seçimi yapmanın tek yolu kullanıcıya bir liste verip seçmesini
      istemektir. Bununla birlikte sunucunun bu seçimi kendiliğinden yapması
      da mümkündür. Tarayıcılar isteğin bir parçası olarak kullanıcı
      tercihlerini de gönderdiğinden bu istendiği gibi çalışır. Örneğin bir
      tarayıcı, kullanıcısınının mümkünse Fransızca içerik tercih ettiğini
      yoksa İngilizce içeriğe de razı olabileceğini belirtebilirdi.
      Tarayıcılar bu tercihleri başlıkta belirtirler. Tarayıcı sadece Türkçe
      içerik istendiğini şöyle belirtebilirdi:
    

    
    Accept-Language: tr
    

    
    Bu tercihin yerine getirilebilmesininin sadece, desteklenen diller
      arasında bu dilin varlığına ve istenen belgenin bu dilde bir
      gösteriminin bulunmasına bağlı oluşuna dikkat ediniz.
    

    
    Daha karmaşık bir istek örneği olarak, tarayıcının Fransızca ve
      İngilizce içerik kabul etmeye ayarlandığını fakat Fransızcayı tercih
      ettiğini ve çeşitli ortam türlerini kabul etmekle birlikte salt metin ve
      diğer metin türlerinden ziyade HTML tercih ettiğini, ayrıca, diğer ortam
      türleri üzerinde GIF veya JPEG tercih ettiğini fakat başka çare yoksa
      her ortam türüne de izin verdiğini belirtiyor olsun:
    

    
    
      Accept-Language: fr; q=1.0, en; q=0.5
    
      Accept: text/html; q=1.0, text/*; q=0.8, image/gif; q=0.6, image/jpeg;
      q=0.6, image/*; q=0.5, */*; q=0.1
    
    

    
    httpd, HTTP/1.1 belirtiminde tanımlanan şekliyle ‘sunucu yönetiminde’
      içerik uzlaşımını destekler. Accept,
      Accept-Language, Accept-Charset ve
      Accept-Encoding istek başlıklarını tamamen destekler.
      httpd ayrıca, RFC 2295 ve RFC 2296’da tanımlanan bir deneysel uzlaşım
      olarak ‘şeffaf’ içerik uzlaşımını da destekler. Fakat ‘özellik
      uzlaşımını’ bu RFC’lerde tanımlandığı gibi desteklemez.
    

    
    Bir özkaynak bir URI (RFC 2396) tarafından betimlenen
      kavramsal bir öğedir. Apache gibi bir HTTP sunucusu, ortam türü,
      karakter kümesi, kodlama ve saire ile tanımlanmış bir bayt dizisi
      şeklindeki her gösterimiyle, özkaynaklara kendi isim alanları dahilinde
      erişim sağlar. Her özkaynağın aynı anda bir veya daha fazla gösterimi
      mevcut olabileceği gibi hiç mevcut olmayabilir de. Eğer çok sayıda
      gösterim mevcutsa, bu özkaynağın uzlaşılabilir
      olduğundan ve her gösteriminin  bir çeşitlilik
      oluşturduğundan bunun da uzlaşımın boyutlarından
      kaynaklandığından bahsedilebilir.

    httpd’de İçerik Uzlaşımı
    

    
    Bir özkaynak üzerinde uzlaşılırken gösterim çeşitlerinin her biri
      hakkında sunucuya bilgi verilmesi gerekir. Bu iki yolla yapılabilir:
    

    
      
      
    • Ya gösterim çeşitlerini içeren dosyaların isimleriyle eşleşmeyi
        sağlayan bir tür eşlemi kullanılır (bir *.var dosyası
        gibi).
      • 

      
    • Ya da sunucu örtük bir dosya ismi kalıbı eşleşmesinin ardından
        sonuçlar arasından seçim yapar; buna ‘Çoklu Görünüm’ araması adı
        verilir.
      • 
    
    

   
    Bir türeşlem dosyası kullanmak
    

    
    Bir türeşlem dosyası, type-map eylemcisi ile ilişkili bir
      belgedir (ya da eski httpd yapılandırmaları ile geriye uyumluluk için,
      application/x-type-map MIME türünde
      bir belgedir). Bu özelliği kullanmak için, yapılandırmada bir tür
      eşleyici olarak her dosya ismi uzantısı için bir type-map
      eylemcisi tanımlamalısınız. Bu, sunucu yapılandırma dosyasında en iyi
      şöyle yapılabilir:
    

    
    AddHandler type-map .var
    


    
    Türeşlem dosyaları kendilerini tanımlayan özkaynak ile aynı isimde
      olmalı ve isim bir .var uzantısı içermelidir. Aşağıdaki
      örneklerde özkaynak ismi foo olduğundan türeşlem dosyasının
      ismi foo.var'dır.
    

    
    Bu dosya her gösterim çeşidi için bir girdi içermelidir; bu girdiler
      ardarda belirtilen HTTP biçem başlık satırlarından oluşur. Farklı
      gösterimlerin girdileri bir boş satırla diğerlerinden ayrılır. Aynı
      girdi içinde boş satır kullanılamaz. Bir eşlem dosyasını bir birleşik
      öğenin tamamı için bir girdi ile başlatmak adet olmuştur (ise de, bu
      gerekli değildir, hele yoksayılacaksa hiç gerekli değildir). Eşlem
      dosyası için aşağıda bir örnek verilmiştir.
    

   
    Bu dosyadaki URI'ler türeşlem dosyasının yerine görelidir. Dolayısıyla,
     bu dosyaların aynı dizinde bulunması beklenirse de bu gerekli değildir.
     Aynı sunucuda bulunan tüm dosyalar için türeşlem dosyasındaki gibi mutlak
     veya göreli URI'ler belirtebilirsiniz.
    

    
    
      URI: misal
    
    
    
      URI: misal.en.html
    
      Content-type: text/html
    
      Content-language: en
    
    
    
      URI: misal.fr.de.html
    
      Content-type: text/html;charset=iso-8859-2
    
      Content-language: fr, de
    
    
    

    
    Ayrıca, MultiViews etkin olsa bile bir türeşlem dosyasının
      dosya ismi uzantılarının taranmasına göre öncelik alacağına dikkat
      ediniz. Eğer gösterimler bu örnekteki resim dosyasında olduğu gibi
      farklı kaynak üstünlüklerine sahipseler, ortam türünün qs
      parametresi kullanılarak kaynak üstünlükleri belirtilebilir: 
    

    
    
      URI: misal
    
    
    
      URI: misal.jpeg
    
      Content-type: image/jpeg; qs=0.8
    
    
    
      URI: misal.gif
    
      Content-type: image/gif; qs=0.5
    
    
    
      URI: misal.txt
    
      Content-type: text/plain; qs=0.01
    
    
    

    
    qs değerleri 0.000-1.000 değer aralığı içinde
      belirtilebilir. 0.000 qs değerine sahip gösterimin asla
      seçilmeyeceğine dikkat ediniz. Bir qs değeri belirtilmeyen
      gösterimlerin kaynak üstünlüğü 1.000 kabul edilir. qs
      parametresinin belirttiği değer istemcinin yeteneklerinden bağımsız
      olarak olası gösterimler arasında göreli bir üstünlük ifade eder.
      Örneğin bir fotoğraf sözkonusu olduğunda bir JPEG dosyasının kaynak
      üstünlüğü bir ASCII çiziminkinden yüksek olacaktır. Diğer taraftan özgün
      resim bir ASCII çizim olduğu takdirde, ASCII çizim, bir JPEG gösterimine
      göre öncelikli olacaktır. Bu nedenle qs değeri özkaynağın
      doğasına bakarak belirlenir.
    

    
    Tanınan başlıkların tam listesini mod_negotiation modülünün
      belgesinde bulabilirsiniz.
    
  

  
    Çoklu Görünümler
    

    
    MultiViews, httpd.conf dosyasındaki veya
      (AllowOverride yönergesinin
      değerine bağlı olarak) .htaccess dosyalarındaki <Directory>, <Location> veya <Files> bölümleri içinde
      Options yönergeleri ile
      belirtilebilen, dizine özgü bir seçenektir. Yalnız, dikkatli olun,
      Options All yaparak MultiViews seçeneğini
      etkin kılamazsınız; seçeneği ismiyle açıkça belirtmelisiniz.
    

    
    MultiViews şöyle etki eder: Sunucudan,
      MultiViews seçeneğinin etkin olduğu /bir/dizin
      dizininden filanca dosyası için bir istekte bulunulmuşsa
      fakat dizinde bu dosya yoksa, sunucu dizin içeriğini
      filanca.* dosyaları için tarar ve bu dosyalar için
      istemcinin ismiyle talep ettiği ortam türlerini ve kodlamaları
      kullanarak bir türeşlem dosyası uydurup bu gösterimler arasından
      istemcinin gereksinimlerine en uygun gösterimi seçer.
    

    
    MultiViews ayrıca, sunucunun bir dizin içeriğini
      listelemeye çalıştığı durumda DirectoryIndex yönergesi ile belirtilen dosya için de bir
      arama tertipleyebilir. Eğer yapılandırma dosyalarında
    

    
    DirectoryIndex index
    


    
    şeklinde bir atama varsa ve dizinde index.html ve
      index.html3 dosyaları varsa sunucu bunlar arasından hakem
      sıfatıyla bir seçim yapacaktır; ama bu ikisi yerine dizinde sadece
      index.cgi mevcutsa sunucu sadece bu dosyayı
      çalıştıracaktır.
    

    
    Okunan dizinde bulunan dosyalar arasında mod_mime
      tarafından tanınan karakter kümesi, içerik türü, dil ve kodlama
      başlıklarına uygun gösterim uzantılarından birine sahip bir dosya yoksa
      sonuç MultiViewsMatch
      yönergesiyle yapılan tanıma bağlı olur. Bu yönerge hangi diğer dosya
      uzantılarının, eylemcilerin veya süzgeçlerin çok gösterimli uzlaşımla
      ilintileneceğini belirler.

    Uzlaşım Yöntemleri
    

    
    httpd’nin, bir türeşlem dosyası veya dizin içindeki bir dosya
      sayesinde belli bir özkaynağın gösterim çeşitlerinin bir listesini elde
      ettikten sonra ‘en uygun’ gösterime karar vermek için kullanabileceği
      iki yöntem vardır. httpd’nin içerik uzlaşım özelliklerinin kullanımı
      sırasında uzlaşımın nasıl yerine getirileceği ile ilgili ayrıntıları
      bilmek aslında gerekli değildir. Bununla birlikte belgenin kalanında bu
      konu açıklanmaya çalışılmıştır.
    

    
    İki uzlaşım yöntemi vardır:
    

    
      
      
    1. Normal durumda sunucu yönetiminde httpd uzlaşım
        algoritması kullanılır. Bu algoritma aşağıda ayrıntılı olarak
        açıklanmıştır. Bu algoritma kullanıldığı zaman, httpd, en iyi sonuca
        ulaşmak için bazen belli boyutların üstünlük katsayılarıyla ‘oynar’.
        httpd’nin bu katsayılarla oynama işini nasıl yaptığı aşağıda daha
        ayrıntılı açıklanmıştır.
      2. 

      
    2. İstemci bu işlem için özellikle RFC 2295’te tanımlanan mekanizmanın
        kullanılmasını isterse şeffaf içerik uzlaşımı
        kullanılır. Bu uzlaşım yöntemi, en uygun gösterimin seçilmesi
        konusunda tarayıcıya tam denetim imkanı verir; dolayısıyla sonuç
        tarayıcının bu işlem için kullandığı algoritmanın başarısına bağlıdır.
        Şeffaf uzlaşım sürecinin bir parçası olarak, tarayıcı, RFC 2296’da
        tanımlanan ‘gösterim çeşidini uzaktan seçme algoritması’nın
        çalıştırılmasını httpd’den isteyebilir.
      3. 
    
    

  
    Uzlaşımın Boyutları
    

    
    
      
      
    
        Boyut

        Açıklama
      
    

      
    
        Ortam Türü

        Tarayıcı ortam türü tercihlerini Accept başlık alanı
          ile belirtir. Her öğenin kendine özgü bir üstünlük katsayısı
          olabilir. Gösterimin açıklaması da ayrıca bir kaynak üstünlüğüne
          (qs parametresi) sahip olabilir.
      
    

      
    
        Dil

        Tarayıcı dil tercihlerini Accept-Language başlık
          alanı ile belirtir. Her öğenin kendine özgü bir üstünlük katsayısı
          olabilir. Gösterimler bir kaç dilde olabileceği gibi hiç bir dille
          ilişkilendirimemiş de olabilir.
      
    

      
    
        Kodlama

        Tarayıcı kodlama tercihlerini Accept-Encoding başlık
          alanı ile belirtir. Her öğenin kendine özgü bir üstünlük katsayısı
          olabilir.
      
    

      
    
        Karakter Kümesi

        Tarayıcı karakter kümesi tercihlerini Accept-Charset
          başlık alanı ile belirtir. Her öğenin kendine özgü bir üstünlük
          katsayısı olabilir. Gösterim çeşitleri karakter kümesini ortam
          türünün bir parametresi olarak belirtebilirler.
      
    
    
    
  

  
    httpd Uzlaşım Algoritması
    

    
    httpd, tarayıcıya döndürülecek en uygun gösterim çeşidini (varsa)
      seçmek için aşağıdaki algoritmayı kullanabilir. Bu algoritma pek de
      yapılandırılabilir değildir. Şöyle çalışır:
    

    
      
      
    1. Önce her uzlaşım boyutu için ilgili Accept* başlık alanına
        bakılıp her gösterim çeşidine bir üstünlük katsayısı atanır. Eğer
        boyutlardan bazıları için ilgili Accept* başlığı
        uygulanabilir değilse bu boyut elenir ve sonuçta hiçbir gösterim
        çeşidi kalmasza 4. adıma atlanır.
      2. 

      
    2. ‘En uygun’ gösterim çeşidi bir eleme süreciyle seçilir. Bu süreç
        sırasında aşağıdaki sınamalar sırayla uygulanır. Sınamalardan
        geçemeyen bir gösterim çeşidi elenir.  Sınamaların bir aşamasında tek
        bir gösterim çeşidi kalırsa bu en uygun eşleşme olarak seçilmiş olur
        ve 3. adıma atlanır. Eğer birden fazla gösterim çeşidi kalırsa sonraki
        sınamaya geçilir.

        
        
          
      1. Accept başlığındaki üstünlük katsayısı ile
            gösterimin ortam türünde belirtilen kaynak üstünlüğünün çarpımı en
            büyük olan gösterim çeşidi seçilir.
        2. 

          
      2. En yüksek dil üstünlük katsayısına sahip gösterim çeşidi seçilir.
          
        3. 

          
      3. En uygun dil eşleşmesine sahip gösterim çeşidini seçmek için
            önce varsa Accept-Language başlığındaki dil
            sıralamasına bakılır, aksi takdirde LanguagePriority
            yönergesi ile atanmışsa oradaki dil sıralamasına bakılır.
        4. 

          
      4. En yüksek ‘seviyeden’ ortam parametresine (text/html ortam türü
            sürümünü belirtmekte kullanılır) sahip gösterim çeşitleri
            seçilir.
        5. 

          
      5. Accept-Charset başlık satırında belirtilene bakarak
            en uygun karakter kümesine sahip gösterim çeşitleri seçilir.
            Alenen dışlanmadıkça ISO-8859-1 kabul edilebilir karakter
            kümesidir. text/* ortam türüne sahip gösterim
            çeşitlerinden belli bir karakter kümesi ile ilişkilendirilmemiş
            olanların karakter kümesinin ISO-8859-1 olduğu varsayılır.
        6. 

          
      6. ISO-8859-1 karakter kümesi ile ilişkilendirilmemiş gösterim
            çeşitleri seçilir. Böyle hiçbir gösterim yoksa bütün gösterimler
            seçilir.
        7. 

          
      7. En uygun kodlamaya sahip gösterim çeşitleri seçilir. Tarayıcı
            tarafından kabul edilebilir kodlamaya sahip gösterim çeşitleri
            varsa bunlar seçilir. Yoksa kodlanmış ve kodlanmamış gösterim
            çeşitleri karışık olarak mevcutsa sadece kodlanmamış olanlar
            seçilir. Eğer bütün gösterim çeşitlerinin sadece kodlanmış ya da
            sadece kodlanmamış gösterimleri mevcutsa hepsi seçilir.
        8. 

          
      8. En küçük içerik uzunluğuna sahip gösterim çeşitleri seçilir.
        9. 

          
      9. Kalan gösterim çeşitlerinin ilki seçilir. Bu ilk, ya türeşlem
            dosyasında listelenen ilk çeşittir ya da gösterimler bir dizinden
            okunuyorsa ASCII kod sıralamasına göre ilk sıradaki dosya ismine
            sahip gösterimdir.
        10. 
        
      
      
      3. 

      
    3. Algoritma, artık seçilmiş en uygun gösterim çeşidine sahipse bu
        artık yanıt olarak döndürülebilir. HTTP yanıt başlığı
        Vary’ye uzlaşım boyutları atanır (tarayıcı ve
        arabellekler özkaynağı kaydederken bu bilgiyi kullanırlar)
        ve algoritma sonlandırılır.
      4. 

      
    4. Buraya gelinmişse hiçbir gösterim seçilmemiş demektir (hiçbiri
        tarayıcı tarafından kabul edilebilir bulunmadığından dolayı).
        Gövdesinde mevcut gösterim çeşitlerini listeleyen bir HTML belgesi 406
        durum koduyla döndürülür (406: ‘kabul edilebilir bir gösterim yok’).
        Ayrıca HTTP Vary başlığında gösterim çeşitliliğinin
        boyutları belirtilir.
      5.

    Üstünlük Değerleriyle Oynamak
    

    
    httpd bazen yukarıdaki httpd uzlaşım algoritmasının kesin sonucunun
      beklenenden farklı olması için üstünlük değerleriyle oynar. Bunu tam ve
      doğru bilgi göndermeyen tarayıcılar için algoritmadan en iyi sonucu elde
      etmek amacıyla yapar. Bazen günümüzün en tanınmış tarayıcıları bile çoğu
      durumda yanlış bir seçimle sonuçlanmayacaksa Accept başlık
      bilgilerini göndermemektedir. Eğer tarayıcı eksiksiz ve doğru bilgi
      gönderirse httpd bu değerlerle oynamayacaktır.
    

  
    Ortam Türleri ve Dosyaismi Kalıpları
    

    
    Accept: istek başlığı ortam türü tercihlerini yansıtır.
      Ayrıca, * bir dizge ile eşleşmek üzere "image/*" veya  "*/*" gibi ortam
      türü kalıpları da içerebilir. Dolayısıyla şöyle bir istek,
    

    
    Accept: image/*, */*
    

    
    diğer türler gibi "image/" ile başlayan ortam türlerini kabul
      edilebilir kılacaktır. Bazı tarayıcılar ortam türlerini örtük olarak
      elde etmek amacıyla hep bu tür kalıplar gönderirler. Örnek:
    

    
    
      Accept: text/html, text/plain, image/gif, image/jpeg, */*
    
    

    
    Bunun amacı, açıkça listelenmiş türlerin tercih edildiğini, fakat
      farklı gösterimler varsa onların da kabul edilebileceğini belirtmektir.
      Üstünlük değerlerini doğrudan kullanarak tarayıcılar gerçekte ne
      istediklerini şuna benzer şekilde belirtebilirler:
    

    
    
      Accept: text/html, text/plain, image/gif, image/jpeg, */*; q=0.01
    
    

    
    Açıkça belirtilen türler için üstünlük katsayısı belirtilmemiştir,
      dolayısıyla üstünlük katsayılarının 1.0 (en yüksek) olduğu
      varsayılmaktadır. */* kalıbı 0.01 gibi çok daha düşük bir öncelik
      belirtmektedir. Bu bakımdan, ancak, açıkça belirtilen türlerden
      hiçbirinin bulunmaması halinde diğer türler eşleşecektir.
    

    
    Eğer Accept: başlığı hiçbir q
      katsayısı içermiyorsa ve başlıkta "*/*" belirtilmişse, httpd istenen
      davranışı taklit etmek için bu kalıba 0.01 katsayısını atar. Keza
      "type/*" kalıbına da 0.02 katsayısını atar (yani, */* kalıbına göre
      tercihli olur). Eğer  Accept: alanındaki her ortam türü bir
      q katsayısı içeriyorsa bu özel değerler uygulanmaz.
      Dolayısıyla gerekli bilgiyi açıkça bildiren tarayıcılardan gelen
      istekler umulduğu gibi işlem görecektir.
    
  

  
    Dil Uzlaşımında İstisnalar
    

    
    httpd 2.0’dan itibaren, uzlaşım algoritmasına, bir eşleşme bulmak
      konusunda algoritma başarılı olamadığı takdirde hoş bir son çareye izin
      vermek için bazı istisnalar eklenmiştir.
    

    
    İstemci sunucudan bir sayfa istediğinde, sunucu, tarayıcı tarafından
      gönderilen Accept-language başlığıyla eşleşen tek bir sayfa
      bulamadığı takdirde istemciye ya “Kabul edilebilir bir gösterim çeşidi
      yok” ya da “Çok sayıda seçim belirtilmiş” yanıtını döndürür. Bu hata
      iletilerinden kaçınmak için bu gibi durumlarda httpd
      Accept-language başlığını yoksaymaya ayarlanabilir. Böylece
      istemcinin isteğine tam olarak uymasa da bir belge sağlanır. Bu hata
      iletilerinin birini veya her ikisini de geçersiz kılmak için ForceLanguagePriority yönergesi
      kullanılabilir ve sunucunun kararını LanguagePriority yönergesine
      dayanarak vermesi sağlanabilir.
    

    
    Sunucu ayrıca, tam bir eşleşme bulunmadığı zaman lehçelerle de eşleşme
      arayabilir. Örneğin, bir istemci Britanya İngilizcesi
      (en-GB) ile yazılmış belgeler için istekte bulunursa,
      sunucu normalde HTTP/1.1 standardına göre bir belgenin basitçe
      en olarak imlenmesine izin vermez. (Bir okuyucu Britanya
      İngilizcesini anlıyor ama genel İngilizceyi anlamıyor diye
      Accept-Language başlığında en  değil de
      en-GB’yi belirtmesinin hemen hemen daima bir yapılandırma
      hatasına yol açacağına dikkat ediniz. Maalesef, mevcut istemcilerin çoğu
      öntanımlı yapılandırmalarında buna benzer şeyler yapmaktadır.) Bununla
      birlikte, başka bir dille eşleşme mümkün değilse ve sunucu “Kabul
      edilebilir bir gösterim çeşidi yok” hatasını döndürmeye hazırsa veya
      LanguagePriority son
      çaresine ayarlanmışsa alt küme belirtimini yok sayacak ve
      en belge isteklerine en-GB belgelerle yanıt
      verecektir. httpd, lehçenin üyesi olduğu anadili, istemcinin kabul
      edilebilir diller listesine örtük olarak düşük bir üstünlük değeri ile
      ekler. Yalnız şuna dikkat edin, eğer istemci tercihini "en-GB; q=0.9,
      fr; q=0.8" olarak belirtirse ve sunucuda sadece "en" ve "fr" belgeleri
      varsa sunucu "fr" belge ile yanıt verecektir. HTTP/1.1 belirtimi ile
      uyumluluğu sağlamak ve düzgün yapılandırılmış istemcilerle gerektiği
      gibi çalışabilmek için bu gereklidir.
    

    
    Gelişmiş tekniklerin (çerezler, özel URL yolları gibi) desteklenmesi
      sırasında, kullanıcının tercih ettiği dili saptamak için httpd 2.0.47
      sürümünden beri mod_negotiation modülü
      prefer-language ortam değişkenini
      tanımaktadır. Değişken mevcutsa ve uygun bir dil yaftası içeriyorsa
      mod_negotiation uygun gösterimi seçmeyi deneyecektir.
      Böyle bir gösterim çeşidi mevcut değilse normal uzlaşım işlemi
      uygulanacaktır.
    

    
    Örnek
    SetEnvIf Cookie "language=(.+)" prefer-language=$1
Header append Vary cookie

    Şeffaf İçerik Uzlaşımının Genişletilmesi
    
  

  
    httpd, şeffaf içerik uzlaşımı protokolünü (RFC 2295) şöyle genişletir:
    Sadece içerik kodlamasına özgü olmak üzere gösterim çeşidi listelerinde
    gösterim çeşitlerini imlemek için yeni bir {encoding ..}
    elemanı kullanılır. RVSA/1.0 algoritmasının (RFC 2296) gerçeklenimi,
    listedeki kodlanmış gösterim çeşitlerini tanımak ve onları
    Accept-Encoding başlık alanıyla ilgili olarak kabul
    edilebilir kodlamalara aday gösterim çeşitleri olarak kullanmak üzere
    genişletilmiştir. RVSA/1.0 gerçeklenimi, en uygun gösterim çeşidi
    seçiminin öncesinde hesaplanmış üstünlük katsayısını virgülden sonra beş
    haneye yuvarlamaz.

    Hiperbağlar ve İsimlendirme Uzlaşımları
    

    
    Eğer dil uzlaşımı kullanıyorsanız ve birden fazla dosya ismi uzantısına
      sahip dosyalarınız varsa uzantıların sıralamasının normalde uygunsuz
      düştüğü farklı isimlendirme yaklaşımlarında bulunabilirsiniz (ayrıntılar
      için mod_mime belgesine
      bakınız).
    

    
    Bir MIME türü uzantısına sahip bir dosyanın (html gibi),
      kodlanmış bir gösterimi (gz gibi) mevcut olabilir. Bu
      dosyanın ayrıca farklı dillerdeki gösterimleri için de bir uzantısı
      (en gibi) olabilir.
    

    
    Örnekler:
    

    
      
      
    • misal.en.html
      • 

      
    • misal.html.en
      • 

      
    • misal.en.html.gz
      • 
    
    

    
    Hiperbağ olarak geçerli ve geçersiz bazı dosya ismi örnekleri:
    

    
    
      
      
    
        Dosya ismi

        Geçerli Hiperbağ

        Geçersiz Hiperbağ
      
    

      
    
        misal.html.en

        misal
    
         misal.html    		

        -
      
    

      
    
        misal.en.html

        misal

        misal.html
      
    

      
    
        misal.html.en.gz

        misal
    
         misal.html    		

        misal.gz
    
         misal.html.gz    		
      
    

      
    
        misal.en.html.gz

        misal

        misal.html
    
         misal.html.gz
    
         misal.gz    		
      
    

      
    
        misal.gz.html.en

        misal
    
         misal.gz
    
         misal.gz.html    		

        misal.html
      
    

      
    
        misal.html.gz.en

        misal
    
         misal.html
    
         misal.html.gz    		

        misal.gz
      
    
    
    

    
    Yukarıdaki tabloya bakarak hiperbağlarda bir dosya ismini uzantısız
      olarak (misal gibi) kullanmanın daima mümkün olduğunu
      farkedeceksiniz. Böylece bir belgenin asıl türünü gizleyebilir ve
      sonradan bir hiperbağ değişikliği yapmaksızın örneğin
      html’den shtml veya cgi’ye
      geçebilirsiniz.
    

    
    Hiperbağlarda MIME türlerini (misal.html gibi) kullanmaya
      devam etmek istiyorsanız dil uzantısı MIME türü uzantısının sağında
      kalmalıdır (misal.html.en gibi).

    Arabellekler Hakkında
    

    
    Bir arabellek, bir gösterimi istek URL’si ile ilişkilendirerek saklar.
      Böylece, sonradan aynı URL için bir istek yapıldığında kaydettiği
      gösterimi kullanabilir. Fakat özkaynak sunucuyla uzlaşılan türdeyse
      arabelleğe ilk istenen çeşit saklanmış olacağından isteğe yanlış
      gösterimle yanıt verilmiş olacaktır. Bunun olmaması için httpd, normal
      olarak içerik uzlaşımının sonucu olarak döndürülen tüm yanıtları
      HTTP/1.0 istemciler tarafından arabelleklenemez olarak imler. httpd
      ayrıca, uzlaşımlı yanıtların arabelleklenmesini mümkün kılan HTTP/1.1
      protokolünü de destekler.
    

    
    HTTP/1.0 uyumlu istemcilerden (bir tarayıcı veya arabellek) gelen
      istekler için, uzlaşıma konu yanıtların arabelleklenmesini mümkün kılmak
      üzere CacheNegotiatedDocs yönergesi kullanılabilir. Bu yönerge
      argümansızdır ve sunucu genelinde veya sanal konakların
      yapılandırılmasında kullanılabilir. Bunun HTTP/1.1 istemcilerinden gelen
      isteklere bir etkisi yoktur.
    

    
    HTTP/1.1 istemciler için, httpd, yanıtın uzlaşım boyutlarını göstermek
      üzere bir Vary HTTP yanıt başlığı gönderir. Arabellekler bu
      bilgiyi sonraki istekleri yerel kopyadan sunarken kullanabilirler. Bir
      arabelleğin uzlaşım boyutlarına bakmaksızın yerel kopyasını kullanmaya
      teşvik etmek için force-no-vary ortam değişkenini etkin kılabilirsiniz.

    Ce document explique le fonctionnement de certaines directives du serveur
de base qui sont utilisées pour configurer les opérations élémentaires du
serveur.
    

    


    top
    

    

    Identification du serveur
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Les directives ServerAdmin et
    ServerTokens contrôlent la nature des
    informations à propos du serveur qui seront affichées dans les documents
    générés par le serveur comme les messages d'erreur. La directive
    ServerTokens définit la valeur du
    champ d'en-tête de la réponse du serveur HTTP.
    

    
    Le serveur utilise les directives
    ServerName,
    UseCanonicalName et
    UseCanonicalPhysicalPort pour
    déterminer la manière de construire des URLs vers ses propres ressources.
    Par exemple, quand un client émet une requête vers un répertoire, mais
    n'ajoute pas le slash final au nom du répertoire, httpd doit rediriger le
    client vers le nom complet incluant le slash final afin que le client
    puisse résoudre correctement les références relatives présentes dans
    le document.
    
  
    top
    

    

    Localisation des fichiers
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Ces directives contrôlent la localisation des différents fichiers
    nécessaires au bon fonctionnement de httpd. Quand le chemin utilisé ne
    commence pas par un slash (/), la localisation des fichiers est relative
    à la valeur de la directive
    ServerRoot. Soyez prudent avec la
    localisation de fichiers dans des répertoires où les utilisateurs non root
    ont les droits en écriture. Voir la documention sur les
    Conseils à propos
    de la sécurité pour plus de détails.
    
  
    top
    

    

    Limitation de l'utilisation des ressources
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Les directives LimitRequest* permettent de
    limiter la quantité de ressources consommées par httpd pour le traitement
    des requêtes des clients. Cette limitation permet de minimiser les effets
    de certains types d'attaques par déni de service.
    

    
    Les directives RLimit* permettent de limiter la
    quantité de ressources utilisable par les processus initiés (forked) par
    les processus enfants httpd. Elles permettent en particulier de contrôler
    les ressources utilisées par les scripts CGI et les commandes exec des
    "Inclusions côté serveur" (Server Side Includes ou SSI).
    

    
    La directive ThreadStackSize
    permet sur certaines plates-formes de contrôler la taille de la pile.
    
  
    top
    

    

    Choix d'implémentation
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    La directive Mutex permet de modifier
    l'implémentation sous-jacente des mutex, afin de résoudre les
    problèmes de fonctionnement ou de performance dus au choix par
    défaut d'APR.

    top
    

    

    Prérequis
    

    
    Les prérequis pour la construction d'Apache httpd sont les suivants:
    

    
    
      
    APR et APR-Util
    
      
    APR et APR-Util doivent être déjà installés sur votre système.
      Si ce n'est pas le cas, ou si vous préférez ne pas utiliser les
      versions fournies par le système, téléchargez les dernières
      versions d'APR et APR-Util depuis Apache APR, décompressez-les
      respectivement dans /racine_sources_httpd/srclib/apr et
      /racine_sources_httpd/srclib/apr-util (les noms des répertoires ne
      doivent pas comporter de numéros de versions ; par exemple, la
      distribution d'APR doit se trouver dans /racine_sources_httpd/srclib/apr/), et
      utilisez l'option --with-included-apr du script
      ./configure. Sur certaines plateformes, vous devrez
      peut-être installer les paquets -dev correspondants
      pour permettre la compilation de httpd avec les versions
      installées d'APR et APR-Util.
    

      
    Bibliothèque d'expressions rationnelles compatibles Perl
      (PCRE)
    
      
    Cette bibliothèque est nécessaire mais n'est plus fournie avec la
      distribution de httpd. Téléchargez le code source depuis http://www.pcre.org ou installez
      un portage du paquet. Si votre suite de compilation ne trouve pas
      le script pcre-config installé au cours du processus de
      construction de PCRE, indiquez son chemin via l'option
      --with-pcre du script ./configure. Sur
      certaines plateformes, vous devrez
      peut-être installer les paquets -dev correspondants
      pour permettre la compilation de httpd avec la version
      installée de PCRE.
    

      
    Espace disque
    
      
    Assurez-vous d'avoir au moins 50 Mo d'espace disque disponible
      temporaire. Après l'installation le serveur occupe
      approximativement 10 Mo d'espace disque. L'espace disque réellement
      nécessaire va varier considérablement en fonction de vos options
      de configuration, de la présence éventuelle de
      modules tiers, et bien entendu de la taille de votre site web et
      des sites que vous hébergez sur votre serveur.
    

      
    Compilateur ANSI-C et système de construction
    
      
    Vous devez disposer d'un compilateur ANSI-C. Le compilateur GNU C (GCC) de la Free Software Foundation (FSF)
      est recommandé. Si vous ne possédez pas GCC,
      assurez-vous au moins que votre compilateur soit compatible ANSI.
      En outre, votre PATH doit contenir
      les outils de construction de base tels que make.
    

      
    Connaissance de l'heure exacte
    
      
    Les éléments du protocole HTTP font référence à l'heure du jour.
      Par conséquent, il est nécessaire d'équiper votre système d'un
      dispositif de synchronisation du temps. Les programmes
      ntpdate ou xntpd, basés sur le protocole NTP,
      sont couramment utilisés à cet effet.
      Voir la page d'accueil de NTP
      pour plus de détails à propos du logiciel NTP et des serveurs
      de temps publics.
    

      
    Perl 5
      [OPTIONNEL]
    
      
    L'interpréteur Perl 5 (les versions 5.003 ou supérieures conviennent)
      est nécessaire pour l'exécution de certains scripts comme
      apxs ou dbmmanage
      (qui sont écrits en Perl).
      Si le script configure ne trouve pas d'interpréteur
      Perl 5, vous ne pourrez pas utiliser les scripts qui en ont besoin.
      Bien entendu, vous pourrez tout de même construire et utiliser
      Apache httpd.

    Téléchargement
    

    
    Le serveur HTTP Apache peut être téléchargé à partir du
    site de téléchargement
    du serveur HTTP Apache, qui fournit la liste de nombreux miroirs.
    Il sera plus commode à la plupart des utilisateurs d'Apache sur les
    systèmes UNIX ou similaires de télécharger et de compiler
    la version sources.  Le processus de construction (décrit ci-dessous) est
    simple, et vous permet de personnaliser votre serveur selon vos besoins.
    En outre, les versions binaires sont souvent plus anciennes que les
    dernières versions sources. Si vous téléchargez une version binaire,
    suivez les instructions décrites dans le fichier
    INSTALL.bindist inclus dans la distribution.
    

    
    Après le téléchargement, il est important de vérifier que vous
    disposez d'une version complète et non modifiée du serveur HTTP Apache.
    Vous pouvez le faire en testant l'archive téléchargée à l'aide de
    la signature PGP. Vous trouverez les détails de cette opération sur la page de téléchargement ainsi qu'un exemple précis décrivant l'utilisation de
    PGP.
    


    top
    

    

    Extraction
    

    
    L'extraction des sources depuis l'archive du serveur HTTP Apache consiste
    simplement à décompresser et à désarchiver cette dernière :
    


    
$ gzip -d httpd-NN.tar.gz
    
$ tar xvf httpd-NN.tar

    

    
    Ceci créera, dans le répertoire courant, un nouveau répertoire
    contenant le code source de la distribution. Vous devrez vous positionner
    dans ce répertoire avant de procéder à la compilation du serveur.
    

    top
    

    

    Configuration de l'arborescence des sources
    

    
    L'étape suivante consiste à configurer l'arborescence des sources
    d'Apache en fonction de votre plateforme et de vos besoins personnels.
    Le script  configure, situé à la racine du
    répertoire de la distribution, a été conçu à cet effet
    (Les développeurs qui téléchargent
    une version non officielle de l'arborescence des sources d'Apache
    devront disposer de
    autoconf et libtool et
    exécuter buildconf avant de passer à l'étape suivante,
    ce qui n'est pas nécessaire pour les versions officielles).
    

    
    Pour configurer l'arborescence des sources avec les valeurs par défaut
    pour toutes les options, entrez simplement ./configure.
    Pour modifier les valeurs des options, configure
    accepte toute une variété de variables et
    d'options de ligne de commande.
    

    
    L'option la plus importante --prefix est le chemin
    du répertoire d'installation d'Apache, car Apache doit être configuré
    en fonction de ce chemin pour pouvoir fonctionner correctement.
    Il est possible de définir plus finement le chemin d'installation des fichiers
    à l'aide d'options
    supplémentaires de configure.
    

    
    À ce niveau, vous pouvez aussi spécifier de quelles fonctionnalités vous
    voulez disposer dans Apache en activant ou désactivant des modules.  Apache est fourni avec un grand nombre de
    modules inclus par défaut. Ils seront compilés en tant qu'objets partagés (DSOs) qui pourront être chargés
    ou déchargés à l'exécution. Vous pouvez aussi choisir de compiler
    les modules statiquement via l'option
    --enable-module=static.
    
    
    Des modules supplémentaires peuvent être activés à l'aide de l'option
    --enable-module, où
    module est le nom du module sans la chaîne
    mod_ et où tout caractère de soulignement est converti
    en tiret. D'une manière similaire,
    vous pouvez désactiver des modules à l'aide de l'option
    --disable-module.  Faites très attention
    en utilisant ces options, car configure n'est pas en
    mesure de vous avertir si le module que vous avez spécifié n'existe pas;
    il ignorera tout simplement l'option.
    

    
    En outre, vous devrez peut-être fournir au script
    configure des informations supplémentaires sur
    le chemin de votre compilateur, de vos bibliothèques, ou de vos fichiers
    d'en-têtes.  A cet effet, vous pouvez passer des options de ligne de
    commande ou des variables d'environnement au script
    configure. Pour plus d'informations, voir la
    page de manuel de configure, ou lancez le script
    configure avec l'option --help.
    
    

    
    Pour vous faire une idée des possibilités qui s'offrent à vous, voici
    un exemple typique de compilation d'Apache avec le répertoire
    d'installation /sw/pkg/apache, un compilateur et des drapeaux
    particuliers et les deux modules additionnels mod_ldap
    et mod_lua :
    


    
      $ CC="pgcc" CFLAGS="-O2" \
    
       ./configure --prefix=/sw/pkg/apache \
    
       --enable-ldap=shared \
    
       --enable-lua=shared

    

    
    Plusieurs minutes peuvent être nécessaires à
    configure pour tester la disponibilité des
    fonctionnalités
    au sein de votre système, et construire les Makefiles qui seront utilisés
    par la suite pour compiler le serveur.
    

    
    Vous trouverez une description détaillée des options de
    configure dans sa page de manuel.
    

    top
    

    

    Construction
    

    
    Vous pouvez maintenant construire les différents éléments qui
    composent le paquet Apache en lançant tout simplement la commande :
    


    $ make
    

    
    Vous devez être patient, car il faut plusieurs minutes pour compiler
    une configuration de base, et cette durée peut varier considérablement
    en fonction de votre matériel et du nombre de modules que vous avez activés.
    

    top
    

    

    Installation
    

    
    Il est temps maintenant d'installer le paquet dans le répertoire
    d'installation défini par PREFIX (voir plus haut l'option
    --prefix) en lançant:
    


    $ make install
    

    
    Cette étape nécessite habituellement les privilèges
    de root, car PREFIX est en général un
    répertoire possèdant des droits en écriture
    restreints.
    

    
    Si vous effectuez une mise à jour, l'installation n'écrasera pas
    vos fichiers de configuration ou autres documents.
    

    top
    

    

    Personnalisation
    

    
    Ensuite, vous pourrez personnaliser votre Serveur HTTP Apache en
    éditant les fichiers de configuration
    situés dans PREFIX/conf/.
    


    $ vi PREFIX/conf/httpd.conf
    

    
    Consultez le manuel d'Apache situé dans
    PREFIX/docs/manual/ ou
    http://httpd.apache.org/docs/2.4/ pour la version la plus
    récente de ce manuel et la liste complète des directives de configuration disponibles.
    

    top
    

    

    Test
    

    
    Vous pouvez maintenant démarrer votre
    serveur HTTP Apache en lançant:
    


    $ PREFIX/bin/apachectl -k start
    

    
    Vous devriez alors pouvoir requérir votre premier document
    à l'aide de l'URL http://localhost/. La page web que vous
    voyez est située dans le répertoire défini par la directive
    DocumentRoot,
    qui est généralement PREFIX/htdocs/.
    Pour arrêter le serveur, lancez:
    


    $ PREFIX/bin/apachectl -k stop
    

    top
    

    

    Mise à jour
    

    
    La première étape d'une mise à jour consiste à lire l'annonce de la
    sortie de la nouvelle version et le fichier CHANGES
    dans la distribution des sources afin de déceler toutes les modifications
    qui pourraient affecter votre site. Lors d'un changement majeur de version
    (par exemple de 2.0 à 2.2 ou de 2.2 à 2.4),
    il y aura certainement des différences importantes quant à la
    configuration de la compilation et de l'exécution qui nécessiteront des
    ajustements manuels.  Tous les
    modules devront aussi être mis à jour pour qu'ils s'adaptent aux
    changements de l'API des modules.
    

    
    La mise à jour d'une version mineure à la suivante (par exemple, de
    2.2.55 à 2.2.57) est plus aisée.  Le processus make install
    n'écrasera aucun de vos documents existants, fichiers de log,
    ou fichiers de configuration.  De plus, les développeurs font tout
    leur possible pour éviter les changements entraînant une
    incompatibilité dans les options de
    configure, la configuration de l'exécution, ou l'API
    des modules d'une version mineure à l'autre.  Dans la plupart des cas,
    vous pourrez utiliser une ligne de commande
    configure identique, le même fichier de configuration,
    et tous vos modules continueront de fonctionner.
    

    
    Pour effectuer une mise à jour entre deux versions mineures,
    commencez par trouver le fichier
    config.nice dans le répertoire de construction
    de votre serveur installé ou à la racine de l'arborescence des sources
    de votre ancienne installation.  Il contient la reproduction exacte de la
    ligne de commande configure que vous avez utilisée pour
    configurer l'arborescence des sources.  Ensuite, pour mettre à jour
    l'ancienne version vers la nouvelle,
    il vous suffit de copier le fichier config.nice dans
    l'arborescence des sources de la nouvelle version, de l'éditer pour
    effectuer toute modification souhaitée, et de lancer :
    

    
    
    $ ./config.nice
    
    $ make
    
    $ make install
    
    $ PREFIX/bin/apachectl -k graceful-stop
    
    $ PREFIX/bin/apachectl -k start
    
    
    

    
    Vous devez toujours effectuer un test de la nouvelle
    version dans votre environnement avant de la mettre en production.
    Par exemple, vous pouvez installer et exécuter la nouvelle version
    en parallèle avec l'ancienne en utilisant une option
    --prefix et un port différents (en ajustant la directive
    Listen) afin de déceler toute
    incompatibilité avant d'effectuer la mise à jour définitive.
    

    
    Vous pouvez ajouter des arguments supplémentaires à
    config.nice ; ils seront alors ajoutés aux options de
    votre script configure original :
    

     
    
     $ ./config.nice --prefix=/home/test/apache --with-port=90
     
    

    
    top
    

    

    Paquets tiers
    

    
    De nombreux tiers fournissent leur propre distribution du
    serveur HTTP Apache à installer sur une plate-forme particulière. On
    peut citer les différentes distributions Linux, divers
    paquets tiers Windows, Mac OS X, Solaris et de nombreux autres.
    

    
    Notre license logicielle non seulement permet, mais aussi
    encourage ce genre de redistribution. Cependant, ceci conduit à une
    situation ou l'organisation de la configuration et les valeurs par
    défaut de votre installation du serveur peuvent ne pas correspondre
    à ce qui est écrit dans la documentation. Bien que fâcheuse, cette
    situation n'est pas appelée à évoluer de sitôt.
    

    
    Une  description
    de ces distributions tierces est maintenue dans le wiki du
    serveur HTTP, et doit en refléter l'état actuel. Vous devrez
    cependant vous familiariser par vous-même avec la gestion du paquet
    de votre plate-forme particulière et les procédures d'installation.

    This document covers stopping and restarting Apache HTTP Server on
    Unix-like systems. Windows NT, 2000 and XP users should see
    Running httpd as a
    Service and Windows 9x and ME users should see Running httpd as a
    Console Application for information on how to control
    httpd on those platforms.
    

    


    top
    

    

    Introduction
    

    
    In order to stop or restart the Apache HTTP Server, you must send a signal to
    the running httpd processes.  There are two ways to
    send the signals.  First, you can use the unix kill
    command to directly send signals to the processes. You will
    notice many httpd executables running on your system,
    but you should not send signals to any of them except the parent,
    whose pid is in the PidFile. That is to say you
    shouldn't ever need to send signals to any process except the
    parent. There are four signals that you can send the parent:
    TERM,
    USR1,
    HUP, and
    WINCH, which
    will be described in a moment.
    

    
    To send a signal to the parent you should issue a command
    such as:
    


    kill -TERM `cat /usr/local/apache2/logs/httpd.pid`
    

    
    The second method of signaling the httpd processes
    is to use the -k command line options: stop,
    restart, graceful and graceful-stop,
    as described below.  These are arguments to the httpd binary, but we recommend that
    you send them using the apachectl control script, which
    will pass them through to httpd.
    

    
    After you have signaled httpd, you can read about
    its progress by issuing:
    


    tail -f /usr/local/apache2/logs/error_log
    

    
    Modify those examples to match your ServerRoot and PidFile settings.
    

    top
    

    

    Stop Now
    


    Signal: TERM
    

    apachectl -k stop
    

    

    
    Sending the TERM or stop signal to
    the parent causes it to immediately attempt to kill off all of its
    children. It may take it several seconds to complete killing off
    its children.  Then the parent itself exits. Any requests in
    progress are terminated, and no further requests are served.
    

    top
    

    

    Graceful Restart
    


    Signal: USR1
    

    apachectl -k graceful
    

    

    
    The USR1 or graceful signal causes
    the parent process to advise the children to exit after
    their current request (or to exit immediately if they're not
    serving anything). The parent re-reads its configuration files and
    re-opens its log files. As each child dies off the parent replaces
    it with a child from the new generation of the
    configuration, which begins serving new requests immediately.
    

    
    This code is designed to always respect the process control
    directive of the MPMs, so the number of processes and threads
    available to serve clients will be maintained at the appropriate
    values throughout the restart process.  Furthermore, it respects
    StartServers in the
    following manner: if after one second at least StartServers new children have not
    been created, then create enough to pick up the slack. Hence the
    code tries to maintain both the number of children appropriate for
    the current load on the server, and respect your wishes with the
    StartServers
    parameter.
    

    
    Users of mod_status
    will notice that the server statistics are not
    set to zero when a USR1 is sent. The code was
    written to both minimize the time in which the server is unable
    to serve new requests (they will be queued up by the operating
    system, so they're not lost in any event) and to respect your
    tuning parameters. In order to do this it has to keep the
    scoreboard used to keep track of all children across
    generations.
    

    
    The status module will also use a G to indicate
    those children which are still serving requests started before
    the graceful restart was given.
    

    
    At present there is no way for a log rotation script using
    USR1 to know for certain that all children writing
    the pre-restart log have finished. We suggest that you use a
    suitable delay after sending the USR1 signal
    before you do anything with the old log. For example if most of
    your hits take less than 10 minutes to complete for users on
    low bandwidth links then you could wait 15 minutes before doing
    anything with the old log.
    

    
    
    
    When you issue a restart, a syntax check is first run, to
    ensure that there are no errors in the configuration files.
    If your configuration file has errors in it, you will get an
    error message about that syntax error, and the server will refuse to
    restart. This avoids the situation where the server halts and then
    cannot restart, leaving you with a non-functioning server.
    

    
    This still will not
    guarantee that the server will restart correctly. To check the
    semantics of the configuration files as well as the syntax, you
    can try starting httpd as a non-root user. If there
    are no errors it will attempt to open its sockets and logs and fail
    because it's not root (or because the currently running
    httpd already has those ports bound). If it fails
    for any other reason then it's probably a config file error and the error
    should be fixed before issuing the graceful restart.

    Signal: HUP
    

    apachectl -k restart
    

    

    
    Sending the HUP or restart signal to
    the parent causes it to kill off its children like in
    TERM, but the parent doesn't exit. It re-reads its
    configuration files, and re-opens any log files. Then it spawns a
    new set of children and continues serving hits.
    

    
    Users of mod_status
    will notice that the server statistics are set to zero when a
    HUP is sent.
    


    As with a graceful restart, a syntax check is run before the
restart is attempted. If your configuration file has errors in it, the
restart will not be attempted, and you will receive notification of the
syntax error(s).
    

    top
    

    

    Graceful Stop
    


    Signal: WINCH
    

    apachectl -k graceful-stop
    

    

    
    The WINCH or graceful-stop signal causes
    the parent process to advise the children to exit after
    their current request (or to exit immediately if they're not
    serving anything). The parent will then remove its PidFile and cease listening on
    all ports. The parent will continue to run, and monitor children
    which are handling requests. Once all children have finalised
    and exited or the timeout specified by the GracefulShutdownTimeout has been
    reached, the parent will also exit.  If the timeout is reached,
    any remaining children will be sent the TERM signal
    to force them to exit.
    

    
    A TERM signal will immediately terminate the
    parent process and all children when in the "graceful" state. However
    as the PidFile will
    have been removed, you will not be able to use
    apachectl or httpd to send this signal.
    

    
    The graceful-stop signal allows you to run multiple
    identically configured instances of httpd at the
    same time. This is a powerful feature when performing graceful
    upgrades of httpd, however it can also cause deadlocks and race
    conditions with some configurations.
    

    
    Care has been taken to ensure that on-disk files such as lock files
    (Mutex) and Unix socket files
    (ScriptSock) contain the server
    PID, and should coexist without problem. However, if a configuration
    directive, third-party module or persistent CGI utilises any other on-disk
    lock or  state files, care should be taken to ensure that multiple running
    instances of httpd do not clobber each other's files.
    

    
    You should also be wary of other potential race conditions, such as
    using rotatelogs style piped logging. Multiple running
    instances of rotatelogs attempting to rotate the same
    logfiles at the same time may destroy each other's logfiles.

    Ce document décrit l'utilisation des gestionnaires d'Apache (handlers).

    Qu'est-ce qu'un gestionnaire ?
    
    
    
    Modules ApparentésDirectives Apparentées
    


    
    Un "gestionnaire" est une représentation interne à Apache de l'action
    qui doit être entreprise quand un fichier est appelé. En général, les
    fichiers ont des gestionnaires implicites, basés sur le type du fichier.
    Normalement, tous les fichiers sont traités simplement par le serveur,
    mais certains types de fichiers sont "gérés" séparément.
    

    
    Les gestionnaires peuvent aussi être configurés explicitement,
    soit en fonction des extensions des noms de fichier, soit en fonction
    du chemin du fichier,
    sans faire référence au type de fichier. Ceci a le double avantage d'être
    une solution plus élégante, et aussi d'autoriser à associer à la fois
    un type et un gestionnaire avec un fichier. (Voir aussi Fichiers avec extensions
    multiples.)
    

    
    Les gestionnaires peuvent être soit partie intégrante
    du serveur ou inclus dans un module, soit ajoutés à l'aide de la directive
    Action. Les gestionnaires
    intégrés dans la distribution standard se présentent comme suit :
    

    
      
      
    • default-handler: envoie le fichier en utilisant
      le default_handler(), qui est le gestionnaire utilisé par
      défaut pour traiter les contenus statiques. (core)
      • 

      
    • send-as-is: envoie les fichiers avec en-têtes HTTP
      tels quels. (mod_asis)
      • 

      
    • cgi-script: traite le fichier comme un
      script CGI. (mod_cgi)
      • 

      
    • imap-file: Traite le fichier comme un ensemble
      de règles de descriptions d'images (imagemap).
      (mod_imagemap)
      • 

      
    • server-info: Extrait des informations sur la
      configuration du serveur. (mod_info)
      • 

      
    • server-status: Rédige un rapport sur le statut
      du serveur. (mod_status)
      • 

      
    • type-map: Traite le fichier comme une description
      de type pour la négociation du contenu.
      (mod_negotiation)
      • 
    
    
  
    top
    

    

    Exemples
    
    

    
    Modification d'un contenu statique à l'aide d'un script CGI
    
      

      
    Les directives suivantes vont faire en sorte que les requêtes pour
      des fichiers possédant une extension html déclenchent
      l'exécution du script CGI footer.pl.
    

      
    Action add-footer /cgi-bin/footer.pl
AddHandler add-footer .html
    


      
    À ce moment-là, le script CGI se charge d'envoyer le document
      initialement demandé (référencé par la variable d'environnement
      PATH_TRANSLATED) et d'effectuer tous ajout ou modification
      voulus.
    

    
    
    Fichiers avec en-têtes HTTP
    
      

      
    Les directives suivantes vont activer le gestionnaire
      send-as-is, qui est utilisé pour les fichiers qui possèdent
      leurs propres en-têtes HTTP. Tous les fichiers situés dans le répertoire
      /web/htdocs/asis/ seront traités par le gestionnaire
      send-as-is, sans tenir compte de l'extension
      de leur nom de fichier.
    

      
    <Directory "/web/htdocs/asis">
    SetHandler send-as-is
</Directory>
    


    
  
    top
    

    

    Note du développeur
    
    

    
    Pour implémenter la fonctionnalité des gestionnaires, l'
    API Apache a fait l'objet d'un ajout
    que vous pourriez être amené à utiliser.

    Plus précisément, un nouvel enregistrement a été ajouté à la structure
    request_rec :
    

    
    char *handler
    


    
    Si vous voulez que votre module déclenche l'utilisation d'un
    gestionnaire, il vous suffit de définir r->handler avec
    le nom du gestionnaire à n'importe quel moment avant l'étape
    invoke_handler
    de la requête. Les gestionnaires sont implémentés comme auparavant,
    quoique l'on utilise le nom du gestionnaire à la place d'un type
    de contenu. Bien que ce ne soit pas obligatoire, la convention de nommage
    des gestionnaires stipule l'utilisation d'un mot composé séparé par des
    tirets, sans slashes, afin de ne pas interférer avec l'espace de nommage
    des types de média.

    Bu sayfanın konusu şöyle özetlenebilirdi: Yapılandırma dosyalarınızda
      DNS sorguları yapılmasını gerektirecek ayarlamalardan kaçınınız. Eğer
      yapılandırma dosyalarınızda DNS sorgusu yapılarak çözümlenebilecek
      adresler bulunursa sunucunuz beklenmedik davranışlar (hiç
      başlamayabilir) gösterebileceği gibi hizmet reddi veya hizmet
      hırsızlığı (bazı sanal konakların diğerlerine giden sayfaları çalma
      olasılığı dahil) saldırılarına açık hale gelebilir.
    
  
    


    top
    

    

    Basit Bir Örnek
    
    

    
    # Bu yetersiz bir yapılandırma örneğidir, sunucunuzda kullanmayın.
<VirtualHost falan.fesmekan.dom>
  ServerAdmin filanca@fesmekan.dom
  DocumentRoot "/siteler/fesmekan"
</VirtualHost>
    


    
    httpd’nin beklendiği gibi işlemesi için her sanal konak için iki
      veriye mutlaka ihtiyacı vardır: ServerName ve sunucunun bağlantı kabul edip hizmet
      sunacağı en az bir IP adresi. Yukarıdaki örnekte IP adresi
      bulunmamaktadır, dolayısıyla Apache, falan.fesmekan.dom
      adresi için bir DNS sorgusu yapmak zorundadır. Eğer sunucu,
      yapılandırma dosyasını çözümlediği sırada bir sebeple DNS sunucusuna
      erişemezse bu sanal konak yapılandırılmayacak ve bu sanal konağa
      yapılan isteklere yanıt verilemeyecektir.
    

    
    falan.fesmekan.dom’un 192.168.2.1 IP adresine sahip
      olduğunu varsayarsak yapılandırma şöyle olurdu:
    

    
    # Bu yetersiz bir yapılandırma örneğidir, sunucunuzda kullanmayın.
<VirtualHost 192.168.2.1>
  ServerAdmin filanca@fesmekan.dom
  DocumentRoot "/siteler/fesmekan"
</VirtualHost>
    


    
    Ancak, bu sefer de bu sanal konağın sunucu ismini öğrenmek için
      httpd’nin bir ters DNS sorgusu yapması gerekecektir. Eğer bu sorgu
      başarısız olursa kısmi bir yapılandırmaya gidilir.
      Eğer sanal konak isme dayalı ise sanal konak
      kısmen bile yapılandırılmaz. IP’ye dayalı sanal konaklar büyük oranda
      çalışır, fakat (örneğin, bir Redirect varlığında olduğu gibi) sunucu ismini
      içeren tam bir adres üretilmesini gerektiren bir durumda, sunucu geçerli
      bir adres üretemez.
    

    
    Her iki sorunu da çözen yapılandırma şöyle olurdu:
    

    
    <VirtualHost 192.168.2.1>
  ServerName falan.fesmekan.dom
  ServerAdmin filanca@fesmekan.dom
  DocumentRoot "/siteler/fesmekan"
</VirtualHost>
    

  
    top
    

    

    Hizmet Reddi
    
    

    
    Şöyle bir yapılandırmanız olsun:
    

    
    <VirtualHost falan.fesmekan.dom>
  ServerAdmin filanca@fesmekan.dom
  DocumentRoot "/siteler/fesmekan"
</VirtualHost>

<VirtualHost misal.mesela.dom>
  ServerAdmin falanca@mesela.dom
  DocumentRoot "/siteler/mesela"
</VirtualHost>
    


    
    falan.fesmekan.dom’a 192.168.2.1,
      misal.mesela.dom’a 192.168.2.2 atadığınızı fakat,
      mesela.dom’un DNS kaydının sizin denetiminizde olmadığını
      varsayalım. Bu yapılandırmayla, mesela.dom’u
      fesmekan.dom’a giden tüm trafiği çalabilecek duruma
      getirirsiniz. Bunu gerçekleştirmek için DNS kaydında
      misal.mesela.dom’a 192.168.2.1 adresinin atanması
      yeterlidir. Kendi DNS’lerine sahip olduklarından dolayı
      misal.mesela.dom’a istedikleri IP adresini atamaktan
      onları alıkoyamazsınız.
    

    
    192.168.2.1’e gelen isteklerin hepsine
      (http://falan.fesmekan.dom/biryer şeklinde yazılan
      adresler dahil) mesela.dom sanal konağınca hizmet
      sunulacaktır. Apache’nin gelen istekleri sunduğu sanal konaklarla nasıl
      eşleştirdiğini bilirseniz bunun sebebini kolayca anlarsınız. Bunu
      kabataslak açıklayan  bir belgemiz
      mevcuttur.
    
  
    top
    

    

    "Ana Sunucu" Adresi
    
    

    
    İsme dayalı sanal konak
      desteği, httpd’nin çalıştığı makinenin IP adres(ler)ini de bilmesini
      gerektirir. Bu adresi elde etmek için sunucu, ya sunucu genelinde geçerli
      ServerName yönergesine bakar ya da bir
      C işlevi olan gethostname’i kullanır (işlev, komut
      isteminden hostname komutuna dönen yanıtın aynısını
      döndürür) ve ardından bu adresle ilgili olarak bir DNS sorgusu yapar.
      Bu sorgudan kaçınmanın henüz bir yolu yoktur.
    

    
    Eğer bu sorgunun (DNS sunucusunun çökmüş olması gibi bir nedenle)
      başarısız olabileceğinden korkuyorsanız, makine ismini ve IP adresini
      /etc/hosts dosyanıza yazabilirsiniz (Makinenizin düzgün
      olarak açılabilmesi için zaten bu kaydı yapmış olmanız gerekir).
      Kullandığınız işletim sistemine bağlı olarak bu kaydın
      /etc/resolv.conf veya /etc/nsswitch.conf
      dosyasında bulunması gerekebilir.
    

    
    Herhangi bir nedenle sunucunuz bir DNS sorgusu yapmıyorsa veya
      yapmamalıysa, httpd’yi HOSTRESORDER ortam değişkenine
      "local" değerini atadıktan sonra çalıştırabilirsiniz. Bu
      tamamen işletim sistemine ve kullandığınız çözümleyici kütüphanelere
      bağlıdır. Ayrıca, ortamı denetlemek için mod_env
      kullanmıyorsanız, CGI’ler de bundan etkilenir. En iyisi işletim
      sisteminizin SSS belgelerini ve kılavuz sayfalarını okumaktır.

    Bu Sorunlardan Kaçınmak için İpuçları
    
    

    
      
      
    • VirtualHost yönergelerinizde
        IP adresleri kullanınız.
      • 

      
    • Listen yönergelerinizde
        IP adresleri kullanınız.
      • 

      
    • Tüm sanal konakların ayrı birer ServerName yönergesi olsun.
      • 

      
    • Hiçbir sayfa sunulmayan bir <VirtualHost
        _default_:*> sanal konağınız olsun.
      •

    Apache が使用するアドレスとポートの設定をします。
    
  
    


    top
    

    

    概要
    
    

    
    関連モジュール関連ディレクティブ
    


    
    Apache は起動時に、ローカルマシンのあるポートおよびアドレス
    に対して接続し、リクエストが来るのを待ちます。
    デフォルトではマシンのすべてのアドレスに対して Listen します。
    特定のポートか、特定のアドレスのみか、
    またはそれらの組み合わせで Listen するように指定したい場合もあります。
    異なる IP アドレス、ホスト名、ポートに対して Apache がどのように
    応答するかを制御するバーチャルホスト機能と組み合わせてよく使われます。
    

    
    Listen
    ディレクティブで、特定のポートやアドレス・ポートの組から入ってくる
    リクエストのみを受け付けるようにできます。
    もしポート番号だけが Listen
    ディレクティブで指定された場合は、
    すべてのインターフェースの与えられたポート番号に対して
    Listen します。 IP アドレスとポート番号とが同時に与えられた場合は、
    サーバは与えられたインターフェースのポートを Listen します。
    Listen ディレクティブを複数使って
    Listen するアドレスとポートをいくつも指定できます。
    サーバは指定されたアドレスやポートからのリクエストすべてに
    対して応答します。
    

    
    たとえば、全てのインターフェースのポート 80 と 8000 の両方において
    接続を受け付けるには
    

    
    
      Listen 80
    
      Listen 8000
    
    

    
    とします。
    あるインターフェースでは 80 番で、また、同時に他のインターフェースの
    8000 番ポートで接続を受け付けるには、
    
    

    
    
      Listen 192.0.2.1:80
    
      Listen 192.0.2.5:8000
    
    

    
    とします。
    IPv6 アドレスは、角括弧で次の例のように囲まなければいけません。
    

    
    
      Listen [2001:db8::a00:20ff:fea7:ccea]:80
    
    
  
    top
    

    

    IPv6 の特記事項
    
    

    
    多くのプラットホームで IPv6 がサポートされてきていて、
    APR はこれらのほとんどで IPv6 をサポートしているので、
    Apache は IPv6 ソケットを割り当てて IPv6
    経由で送られてきたリクエストを扱うことができます。
    

    
    IPv6 ソケットが IPv4 と IPv6 コネクションの両方を扱うことができるか
    どうかは、Apache 管理者にとって厄介な問題です。
    IPv4 コネクションを IPv6 ソケットで扱う場合は、
    IPv4 マップされた IPv6 アドレスを使用していて、
    ほとんどのプラットホームではデフォルトで使用可能ですが、
    FreeBSD, NetBSD, OpenBSD では、システム全体としてのポリシーとの整合性から、
    デフォルトでは使用不可に設定されています。
    これらのデフォルトで使用不可のプラットホームであっても、
    特別な configure の
    設定パラメータで Apache の挙動を変化させることができます。
    

    
    一方で、Linux や Tru64 といったプラットホームで IPv4 と IPv6
    の両方を扱うには、マップドアドレスを使用する以外の方法はありません。
    IPv4 と IPv6 のコネクションを最小限のソケットで扱いたいのであれば、
    IPv4 マップの IPv6 アドレスを使用する必要があり、
    --enable-v4-mapped configure
    オプションを指定します。
    

    
    --enable-v4-mapped は、
    FreeBSD, NetBSD, OpenBSD 以外の全てのプラットホームでのデフォルトです。
    ですから、おそらくお手元の Apache はこの設定でビルドされているでしょう。
    

    
    プラットフォームや APR が何をサポートするかに関わらず、
    IPv4 コネクションのみを扱うようにしたい場合は、
    次の例のように全ての
    Listen ディレクティブで
    IPv4 アドレスを指定してください。
    

    
    
      Listen 0.0.0.0:80
    
      Listen 192.0.2.1:80
    
    

    
    条件を満たすプラットホームで、Apache が
    IPv4 と IPv6 のコネクションを別々のソケットで扱うようにしたい場合
    (つまり IPv4 マップのアドレスを無効にしたい場合)
    は、--disable-v4-mapped
    configure
    オプションを指定して、次のように個別指定の
    Listen
    ディレクティブを使用してください。
    --disable-v4-mapped は、
    FreeBSD, NetBSD, OpenBSD プラットホームでのデフォルトです。
    
  
    top
    

    

    バーチャルホストに対してどう働くのか
    
    

    
    Listen ディレクティブ
    でバーチャルホストが実装されるわけではありません。
    Listen は単にメインサーバにどのアドレスとポートを Listen すべきかを
    教えるだけです。
    <VirtualHost>
    ディレクティブが使われない場合は、
    受け入れたリクエストすべてに対して全く同じ挙動をします。
    しかしながら
    <VirtualHost>
    を使って、
    一つ以上のアドレスやポートに対して異なる挙動をするように
    指定することができます。
    VirtualHost を実装するには、まず初めに使用したいアドレスとポートに対して
    サーバが Listen していなければなりません。
    そして、その指定したアドレスとポートでの
    このバーチャルホストの挙動を設定するために、
    <VirtualHost>
    セクションを作ります。もし
    <VirtualHost>
    が Listen していないアドレスとポートに対して
    設定されてしまうと、
    それにはアクセスできないということに注意してください。

    Apache HTTP Sunucusu modüler bir program olup, yönetici sadece bir
      grup modül seçerek sunucuya işlevsellik ekleyebilir. Modüller, Devingen
      Paylaşımlı Nesneler (DSO - Dynamic Shared Object) halinde
      httpd programından ayrı olarak derlenir. DSO modülleri
      sunucunun derlenmesi sırasında derlenebileceği gibi ayrı olarak derlenip
      daha sonra Apache Eklenti Aracı (Apache Extension Tool)
      apxs programı kullanılarak da sunucuya eklenebilir.
    

    
    Bu belgede DSO modüllerinin kullanımının yanında teorisine de
      değinilecektir.

    Gerçeklenim
    


    İlgili Modüllerİlgili Yönergeler
    

    
    Apache httpd modüllerini yüklemek için DSO desteği, Apache httpd
      çekirdeğine durağan olarak ilintilenerek derlenmiş olan
      mod_so adında bir modül tarafından sağlanır.
      core modülünden  başka, bir DSO modülü olamayan tek modül
      mod_so modülüdür. Apache ile dağıtılan hemen hemen tüm
      diğer Apache modülleri bir DSO modülüne yerleştirilebilir. Derlenmiş
      modüller mod_filanca.so biçeminde birer DSO ismi alırlar ve
      her biri istenirse httpd.conf dosyasında
      mod_so modülünün LoadModule yönergesiyle belirtilerek sunucu başlatılırken
      veya yeniden başlatılırken sunucuya yüklenebilir.
    

    
    Kurulum belgesinde açıklandığı gibi, her DSO
      modülü configure programının
      --enable-mods-static seçeneği ile devredışı bırakılabilir.
    

    
    Apache httpd modülleri için (özellikle üçüncü parti modüller için) DSO
      dosyası üretimini kolaylaştırmak amacıyla apxs
      (APache eXtenSion) adında yeni bir destek programı
      kullanılmaktadır. Bu program Apache httpd modüllerini Apache httpd kaynak
      ağacından ayrı olarak derlemek için kullanılabilir. Fikir basittir: Apache
      HTTP Sunucusu derlenirken DSO dosyalarını derlemek için platforma bağımlı
      derleyici ve ilintileyici seçenekleri apxs
      programının içine konur ve make install ile kurulum sırasında
      Apache httpd C başlık dosyaları da kurulur. Böylece
      kullanıcı Apache httpd dağıtımının kaynak ağacına ihtiyaç duymadan ve
      platforma bağımlı derleyici ve ilintileyici seçeneklerini bilmek zorunda
      kalmadan istediği Apache httpd modülünü apxs
      programını kullanarak derleyebilir.
    

    top
    

    

    Kullanım Özeti
    

    
    Apache HTTP Sunucusu 2.x’in DSO özelliklerine bir giriş olarak burada
      kısaca bir bilgi vermekle yetinilecektir:
    

    
      
      
    1. Kaynak dosyası mod_filanca.c dosyasında dağıtılan bir
        özgün Apache htpd modülünü mod_filanca.so isminde
        bir  DSO modülü olarak derlemek ve kurmak için şöyle yapılır:
      


      
  $ ./configure --prefix=/kurulum/yeri --enable-filanca
      
  $ make install

      
      
      2. 

      
    2. Apache HTTP Sunucusunu tüm modüller etkin olarak
        derleyebilirsiniz. Fakat sunucunun başlatılması sırasında sadece temel
        modüller yüklenir.  Daha sonra httpd.conf içindeki
        LoadModule yönergelerini etkin
        veya etkisiz hale getirerek yüklenecek modülleri
        değiştirebilirsiniz.
      


      
$ ./configure --enable-mods-shared=all
      
$ make install

      
      
      3. 

      
    3. Bazı modüller sadece geliştiriciler içindir ve bunlar tüm
        modüllerin derlenmesini (all) seçseniz bile derlenmeyecektir.
        Geliştirici modülleri dehil tüm modülleri derlemek isterseniz
        reallyall kullanınız. Ek olarak, derlenmiş modüller için
        kullanılan LoadModule
        yönergelerinin tamamını --enable-load-all-modules derleme
        seçeneği ile etkin kılabilirsiniz.
      


      
$ ./configure --enable-mods-shared=reallyall --enable-load-all-modules
      
$ make install

      
      
      4. 

      
    4. Kaynak dosyası mod_filanca.c dosyasında dağıtılan bir
        üçüncü parti Apache httpd modülü mod_filanca.so
        isminde bir DSO modülü olarak Apache httpd kaynak ağacının dışında
        apxs kullanarak derlemek ve kurmak için şöyle
        yapılır:
      


      
$ cd /bir/kurulum/yeri
      
$ apxs -c mod_filanca.c
      
$ apxs -aci filanca mod_filanca.la

      
      
      5. 
    
    

    
    Tüm durumlarda derlenen paylaşımlı modülü Apache httpd’nin etkin
      kılabilmesi  için httpd.conf dosyasında o modül için bir
      LoadModule yönergesi
      bulunmalıdır.
    

    
    Ayrıntılı bilgi için apxs belgelerine
      bakınız.

    Artalan Bilgisi
    

    
    Günümüzün Unix türevlerinde var olan bir mekanizma sayesinde
      çalıştırılabilir bir programın adres uzayına çalışma anında yüklenmek
      veya ilintilenmek üzere Devingen Paylaşımlı Nesneler (DSO -
      Dynamic Shared Object) adı verilen, özel bir biçem kullanarak kodlanmış
      program parçaları oluşturulabilir.
    

    
    Bu yükleme normalde iki yolla yapılabilir: Ya çalıştırılabilir
      programın başlatılması sırasında yüklenen ld.so adlı bir
      sistem programınının devingen olarak yüklenmesi ile ya da
      çalıştırılabilir programın içinden Unix yükleyicisine programsal sistem
      arayüzü sağlayan dlopen()/dlsym() sistem çağrılarının elle
      yapılması suretiyle.
    

    
    İlk yöntemde kullanılan DSO’lara genelde paylaşımlı
      kütüphaneler veya DSO kütüphaneleri adı verilir ve
      bunların dosyaları libfilanca.so veya
      libfilanca.so.1.2 biçiminde isimlendirilir. Belli bir
      sistem dizininde (normalde /usr/lib) bulunurlar ve derleme
      sırasında ilintileyici komutuna -lfilanca şeklinde
      belirtilerek çalıştırılabilir programla ilintilenirler. Doğrudan
      çalıştırılabilir koda eklenen bu kodlar Unix yükleyicisinin programın
      başlatılması sırasında kütüphaneyi /usr/lib altında
      libfilanca.so adıyla bulabilmesini sağlar. Kütüphanelerin
      aranacağı yerler ya -R gibi bir ilintileyici seçeneği ile
      koda eklenir ya da arama yolları LD_LIBRARY_PATH ortam
      değişkeni aracılığıyla yapılandırılır. Böylece çalıştırılabilir
      programda henüz çözümlenmemiş simgeler DSO içinde bulunarak
      çözümlenebilir.
    

    
    Çalıştırılabilir program içindeki simgelere normalde DSO içinden
      atıfta bulunulmaz (genel kod kütüphanesinin başka programlarca da
      kullanılması nedeniyle). Bu bakımdan DSO tarafında böyle bir çözümleme
      yapılmaz. Çalıştırılabilir program da DSO’daki simgeleri kendisi
      çözümlemeye uğraşmaz, bu işlemlerden tamamen Unix yükleyicisi
      (ld.so) sorumludur. (Aslında, ld.so’yu
      çağıracak kod, her çalıştırılabilir programın içine ilintilenmiş
      (durağan değil) başlatma kodunun bir parçasıdır.) Programlar tarafından
      ortaklaşa kullanılan kütüphanelerin devingen olarak yüklenmesinin sebebi
      basittir: Kütüphane kodu libc.so gibi bir sistem
      kütüphanesine bir kere kaydedilip disk alanından yer kazanılmış
      olur.
    

    
    İkinci yöntemde kullanılan DSO’lara yine paylaşımlı
      kütüphaneler veya DSO kütüphaneleri adı verilir fakat
      bunların dosyaları geçerli kabule göre filanca.so gibi
      isimlendirilse de genelde keyfi olarak seçilen bir dosya uzantısı
      kullanılarak isimlendirilirler. Bu dosyalar genellikle programa özel bir
      dizinde dururlar ve bu dosyaları kullanacak olan çalıştırılabilir
      programla aralarında özdevimli olarak bağ kurulmamıştır. Bunun yerine,
      çalıştırılabilir program DSO’yu çalışma anında dlopen()
      sayesinde kendi adres uzayına ekler. Çalıştırılabilir program için
      DSO’daki simgeler bu sırada çözümlenmez. Özdevimli olarak devreye
      giren Unix yükleyicisi, (varsa) artakalan simgeleri, çalıştırılabilir
      ihraç edilen simge kümelerini (ve özellikle her yerde hazır ve nazır
      libc.so içindeki tüm simgeleri) kullanarak çözümler. Bu
      yolla DSO, çalıştırılabilir programın simge kümesi bilgilerini sanki
      kendisine baştan durağan olarak ilintilenmiş gibi ulaşabilir.
    

    
    Son olarak, DSO’nun programlama arayüzünün getirilerinden yararlanmak
      amacıyla çalıştırılabilir program, daha sonra dağıtım tabloları vb.
      yerlerde kullanmak üzere dlsym() üzerinden DSO’daki belli
      simgeleri çözümlemek zorundadır. Başka bir deyişle: Çalıştırılabilir
      program ihtiyaç duyduğu her simgeyi kullanmak için kendisi çözümleme
      yapmak zorundadır. Böyle bir mekanizmanın getirisi, programın isteğe
      bağlı parçalarının gerekli olana kadar yüklenmemesidir (böylece daha az
      bellek alanı kullanılır). Gerektiği zaman programın işlevselliğini
      arttırmak amacıyla bu parçalar devingen olarak programa
      yüklenebilir.
    

    
    DSO mekanizmasının bu basit gibi görünen işleyişinde zorluk içeren bir
      adım şudur (başkaları da olabilir): Bir programın işlevselliğini
      genişletmek için DSO kullanılırken (ikinci yöntem) çalıştırılabilir
      programdan DSO için simgelerin çözümlenmesi.  Zorluğun sebebi,
      "tersine çözümleme" yapılmasıdır; çalıştırılabilir programın simge
      kümesindeki DSO simgeleri kütüphane tasarımına aykırı bir şekilde
      çözümlenir ve bu uygulama tüm platformlarda hazır olarak
      desteklenmediği gibi standartlaşmış da değildir. Geçer uygulamada
      çalıştırılabilir programın evrensel simgeleri çoğunlukla yeniden dışa
      verilmez ve bu bakımdan bir DSO içinde kullanılmaları uygun değildir.
      Esas sorun, çalıştırılabilir bir programın işlevselliğini çalışma
      anında genişletmek için DSO kullanımı sırasında ilintileyicinin tüm
      evrensel simgeleri dışa vermesini zorlamanın bir yolunu bulmaktır.
    

    
    Paylaşımlı kütüphane yaklaşımı bu bakımdan türünün tek örneğidir,
      çünkü DSO mekanizması özellikle bunun için tasarlanmıştır, dolayısıyla
      işletim sisteminin sağladığı hemen hemen tüm kütüphaneler için
      kullanılabilir.
    

    top
    

    

    Getiriler ve Götürüler
    

    
    Yukarıda bahsedilen DSO’ya dayalı özelliklerin getirileri
      şunlardır:
    

    
      
      
    • Sunucu paketi çalışma anında daha esnektir çünkü, sunucuyu
        oluşturan parçalar derleme sırasında configure
        seçenekleriyle birleştirilmek yerine httpd.conf içinde
        LoadModule yönergeleri
        sayesinde çalışma anında birleştirilebilmektedir. Bu yolla, örneğin
        tek bir Apache kurulumuyla birbirinden farklı yapılandırmalara sahip
        çok sayıda sunucu çalıştırmak mümkündür. (standart veya SSL sürümü;
        basitleştirilmiş veya devingen sürümü [mod_perl, PHP3], vs.)
      • 

      
    • Sunucu paketi kurulumdan sonra bile üçüncü parti modüllerle kolayca
        genişletilebilir. Bu özellikle, bir Apache temel paketinin yanında
        PHP, mod_perl, mod_security gibi ek paketler oluşturan paket
        dağıtıcılarına büyük yarar sağlar.
      • 

      
    • Yeni Apache httpd modülleri için daha kolay prototip
        geliştirilebilir: Modül kaynak kodunu DSO/apxs çifti
        sayesinde Apache httpd kaynak ağacının dışında derleyip modülün yeni
        bir sürümünü bir apxs -i komutunun ardından
        apachectl restart yaparak çalışan bir Apache HTTP
        Sunucusunda denemek daha kolay hale getirilmiştir.
      • 
    
    

    
    DSO kullanımının götürüleri ise şunlardır:
    

    
      
      
    • İlk yüklemede %20 yavaşlama: Unix yükleyicisi simgeleri çözümlemek
        zorunda olduğundan sunucu ilk başlatılırken yaklaşık %20 daha yavaş
        faaliyete geçer.
      • 

      
    • Çalışma sırasında % 5 yavaşlama: Konumdan bağımsız kodun (PIC -
        Position Independent Code) göreli adresleme için karmaşık oyunlara
        girmesi ve bunun mutlak adresleme kadar hızlı olmaması nedeniyle
        sunucu bazı platformlarda çalışma anında yaklaşık %5 daha yavaş
        çalışabilir.
      • 

      
    • DSO'nun tüm modüller için uygun olmaması: DSO modülleri bazı
        platformlarda diğer DSO temelli kütüphanelerle ilintilenemediğinden
        (ld -lfilanca) DSO mekanizmasını tüm modül türleri için
        kullanamazsınız (örneğin a.out temelli platformlar bu işlevselliği
        ELF temelli platformlar kadar iyi sağlamaz). Başka bir deyişle, DSO
        dosyaları olarak derlenmiş modüllerin kullanabileceği simgeler ya
        Apache httpd temel kodunda vardır ya Apache httpd temel kodunun
        kullandığı C kütüphanesinde (libc) ve diğer durağan ve
        devingen kütüphanelerde vardır ya da konumdan bağımsız kodu içeren
        durağan kütüphane arşivlerinde (libfilanca.a)
        vardır. Diğer modülleri kullanmak için tek şansınız ya Apache httpd
        çekirdeğinin modüle bir atıf içermesini sağlamak ya da modül kodunu
        dlopen() vasıtasıyla yüklemektir.

    Este documento explica como iniciar y parar el servidor Apache
     en sistemas tipo Unix. Los usuarios de Windows NT, 2000 y XP
     deben consultar la sección Ejecutar Apache como un
     servicio y los usuario de Windows 9x y ME deben consultar Ejecutar Apache como una
     Aplicación de Consola para obtener información
     sobre como controlar Apache en esas plataformas.

    Introducción
    

    
    Para parar y reiniciar Apache, hay que enviar la señal
    apropiada al proceso padre httpd que se esté
    ejecutando.  Hay dos maneras de enviar estas señales.  En
    primer lugar, puede usar el comando de Unix kill que
    envía señales directamente a los procesos. Puede que
    tenga varios procesos httpd ejecutandose en su
    sistema, pero las señales deben enviarse solamente al proceso
    padre, cuyo pid está especificado en la directiva PidFile. Esto quiere decir que no
    debe necesitar enviar señales a ningún proceso excepto
    al proceso padre. Hay tres señales que puede enviar al
    proceso padre: TERM, HUP, y USR1, que van a ser descritas a
    continuación.
    

    
    Para enviar una señal al proceso padre debe escribir un
    comando como el que se muestra en el ejemplo:
    


    kill -TERM `cat /usr/local/apache2/logs/httpd.pid`
    

    
    La segunda manera de enviar señales a los procesos
    httpd es usando las opciones de línea de
    comandos -k: stop, restart,
    y graceful, como se muestra más abajo.  Estas
    opciones se le pueden pasar al binario httpd, pero se recomienda que se
    pasen al script de control apachectl, que a su vez los
    pasará a httpd.
    

    
    Después de haber enviado las señales que desee a
    httpd, puede ver como progresa el proceso
    escribiendo:
    


    tail -f /usr/local/apache2/logs/error_log
    

    
    Modifique estos ejemplos para que coincidan con la
    configuración que tenga especificada en las directivas
    ServerRoot y PidFile en su fichero principal de
    configuración.
    

    top
    

    

    Parar Apache
    


    Señal: TERM
    

    apachectl -k stop
    

    

    
    Enviar las señales TERM o stop
    al proceso padre hace que se intenten eliminar todos los procesos
    hijo inmediatamente. Esto puede tardar algunos minutos. Una vez
    que hayan terminado todos los procesos hijo, terminará el
    proceso padre. Cualquier petición en proceso terminará
    inmediatanmente, y ninguna petición posterior será
    atendida.
    

    top
    

    

    Reinicio Graceful
    


    Señal: USR1
    

    apachectl -k graceful
    

    

    
    Las señales USR1 o graceful
    hacen que el proceso padre indique a sus hijos que
    terminen después de servir la petición que estén
    atendiendo en ese momento (o de inmediato si no están
    sirviendo ninguna petición). El proceso padre lee de nuevo
    sus ficheros de configuración y vuelve a abrir sus ficheros
    log. Conforme cada hijo va terminando, el proceso padre lo va
    sustituyendo con un hijo de una nueva generación con
    la nueva configuración, que empeciezan a servir peticiones
    inmediatamente.
    

    
    En algunas plataformas que no permiten usar
    USR1 para reinicios graceful, puede usarse una
    señal alternativa (como WINCH). Tambien puede
    usar apachectl graceful y el script de control
    enviará la señal adecuada para su plataforma.
    

    
    Apache está diseñado para respetar en todo momento la
    directiva de control de procesos de los MPM, así como para
    que el número de procesos y hebras disponibles para servir a
    los clientes se mantenga en los valores adecuados durante el
    proceso de reinicio.  Aún más, está diseñado
    para respetar la directiva StartServers de la siguiente
    manera: si después de al menos un segundo el nuevo hijo de la
    directiva StartServers
    no ha sido creado, entonces crea los suficientes para se atienda
    el trabajo que queda por hacer. Así, se intenta mantener
    tanto el número de hijos adecuado para el trabajo que el
    servidor tenga en ese momento, como respetar la configuración
    determinada por los parámetros de la directiva
    StartServers.
    

    
    Los usuarios del módulo mod_status
    notarán que las estadísticas del servidor
    no se ponen a cero cuando se usa la señal
    USR1. Apache fue escrito tanto para minimizar el
    tiempo en el que el servidor no puede servir nuevas peticiones
    (que se pondrán en cola por el sistema operativo, de modo que
    se no se pierda ningún evento), como para respetar sus
    parámetros de ajuste. Para hacer esto, tiene que guardar el
    scoreboard usado para llevar el registro de los procesos
    hijo a través de las distintas generaciones.
    

    
    El mod_status también usa una G para indicar
    que esos hijos están todavía sirviendo peticiones
    previas al reinicio graceful.
    

    
    Actualmente no existe ninguna manera de que un script con un
    log de rotación usando USR1 sepa con seguridad
    que todos los hijos que se registraron en el log con anterioridad
    al reinicio han terminado. Se aconseja que se use un retardo
    adecuado después de enviar la señal USR1
    antes de hacer nada con el log antiguo. Por ejemplo, si la mayor
    parte las visitas que recibe de usuarios que tienen conexiones de
    baja velocidad tardan menos de 10 minutos en completarse, entoces
    espere 15 minutos antes de hacer nada con el log antiguo.
    

    
    Si su fichero de configuración tiene errores cuando
    haga el reinicio, entonces el proceso padre no se reinciciará
    y terminará con un error. En caso de un reinicio graceful,
    también dejará a los procesos hijo ejecutandose mientras
    existan.  (Estos son los hijos de los que se está saliendo de
    forma graceful y que están sirviendo sus últimas
    peticiones.) Esto provocará problemas si intenta reiniciar el
    servidor -- no será posible conectarse a la lista de puertos
    de escucha. Antes de reiniciar, puede comprobar que la sintaxis de
    sus ficheros de configuracion es correcta con la opción de
    línea de comandos -t (consulte httpd). No obstante, esto no
    garantiza que el servidor se reinicie correctamente. Para
    comprobar que no hay errores en los ficheros de
    configuración, puede intentar iniciar httpd con
    un usuario diferente a root. Si no hay errores, intentará
    abrir sus sockets y logs y fallará porque el usuario no es
    root (o porque el httpd que se está ejecutando
    en ese momento ya está conectado a esos puertos). Si falla
    por cualquier otra razón, entonces casi seguro que hay
    algún error en alguno de los ficheros de configuración y
    debe corregir ese o esos errores antes de hacer un reinicio
    graceful.

    Reiniciar Apache
    


    Señal: HUP
    

    apachectl -k restart
    

    

    
    El envío de las señales HUP o
    restart al proceso padre hace que los procesos hijo
    terminen como si le enviá ramos la señal
    TERM, para eliminar el proceso padre. La diferencia
    está en que estas señales vuelven a leer los archivos de
    configuración y vuelven a abrir los ficheros log. Se genera
    un nuevo conjunto de hijos y se continúa sirviendo
    peticiones.
    

    
    Los usuarios del módulo mod_status
    notarán que las estadísticas del servidor se ponen a
    cero cuando se envía la señal HUP.
    


    Si su fichero de configuración contiene errores, cuando
intente reiniciar, el proceso padre del servidor no se
reiniciará, sino que terminará con un error. Consulte
más arriba cómo puede solucionar este problema.

    Apéndice: señales y race conditions
    

    
    Con anterioridad a la versión de Apache 1.2b9 había
    varias race conditions implicadas en las señales
    para parar y reiniciar procesos (una descripción sencilla de
    una race condition es: un problema relacionado con el momento en
    que suceden las cosas, como si algo sucediera en momento en que no
    debe, y entonces el resultado esperado no se corresponde con el
    obtenido). Para aquellas arquitecturas que tienen el conjunto de
    características "adecuadas", se han eliminado tantas race
    conditions como ha sido posible. Pero hay que tener en cuenta que
    todavía existen race conditions en algunas arquitecturas.
    

    
    En las arquitecturas que usan un ScoreBoardFile en disco, existe la
    posibilidad de que se corrompan los scoreboards. Esto puede hacer
    que se produzca el error "bind: Address already in use"
    (después de usarHUP) o el error "long lost child
    came home!"  (después de usar USR1). En el
    primer caso se trata de un error irrecuperable, mientras que en el
    segundo, solo ocurre que el servidor pierde un slot del
    scoreboard. Por lo tanto, sería aconsejable usar reinicios
    graceful, y solo hacer reinicios normales de forma
    ocasional. Estos problemas son bastante complicados de solucionar,
    pero afortunadamente casi ninguna arquitectura necesita un fichero
    scoreboard. Consulte la documentación de la directiva
    ScoreBoardFile para ver
    las arquitecturas que la usan.
    

    
    Todas las arquitecturas tienen una pequeña race condition
    en cada proceso hijo implicada en la segunda y subsiguientes
    peticiones en una conexión HTTP persistente
    (KeepAlive). Puede ser que el servidor termine después de
    leer la línea de petición pero antes de leer cualquiera
    de las cebeceras de petición. Hay una solución que fue
    descubierta demasiado tarde para la incluirla en versión
    1.2. En teoria esto no debe suponer ningún problema porque el
    cliente KeepAlive ha de esperar que estas cosas pasen debido a los
    retardos de red y a los timeouts que a veces dan los
    servidores. En la practica, parece que no afecta a nada más
    -- en una sesión de pruebas, un servidor se reinició
    veinte veces por segundo y los clientes pudieron navegar sin
    problemas por el sitio web sin encontrar problemas ni para
    descargar una sola imagen ni encontrar un solo enlace roto.

    Issues Regarding DNS and Apache HTTP Server

    This page could be summarized with the statement: don't
    configure Apache HTTP Server in such a way that it relies on DNS resolution
    for parsing of the configuration files. If httpd requires DNS
    resolution to parse the configuration files then your server
    may be subject to reliability problems (ie. it might not start up),
    or denial and theft of service attacks (including virtual hosts able
    to steal hits from other virtual hosts).
    
  
    


    top
    

    

    A Simple Example
    
    

    
    # This is a misconfiguration example, do not use on your server
<VirtualHost www.example.dom>
  ServerAdmin webgirl@example.dom
  DocumentRoot "/www/example"
</VirtualHost>
    


    
    In order for the server to function properly, it absolutely needs
    to have two pieces of information about each virtual host: the
    ServerName and at least one
    IP address that the server will bind and respond to. The above
    example does not include the IP address, so httpd must use DNS
    to find the address of www.example.dom. If for some
    reason DNS is not available at the time your server is parsing
    its config file, then this virtual host will not be
    configured. It won't be able to respond to any hits
    to this virtual host.
    

    
    Suppose that www.example.dom has address 192.0.2.1.
    Then consider this configuration snippet:
    

    
    # This is a misconfiguration example, do not use on your server
<VirtualHost 192.0.2.1>
  ServerAdmin webgirl@example.dom
  DocumentRoot "/www/example"
</VirtualHost>
    


    
    This time httpd needs to use reverse DNS to find the
    ServerName for this virtualhost. If that reverse
    lookup fails then it will partially disable the virtualhost.
    If the virtual host is name-based then it will effectively be
    totally disabled, but if it is IP-based then it will mostly
    work. However, if httpd should ever have to generate a full
    URL for the server which includes the server name (such as when a
    Redirect is issued), then it will fail to generate a valid URL.
    

    
    Here is a snippet that avoids both of these problems:
    

    
    <VirtualHost 192.0.2.1>
  ServerName www.example.dom
  ServerAdmin webgirl@example.dom
  DocumentRoot "/www/example"
</VirtualHost>
    

  
    top
    

    

    Denial of Service
    
    

    
    Consider this configuration snippet:
    

    
    <VirtualHost www.example1.dom>
  ServerAdmin webgirl@example1.dom
  DocumentRoot "/www/example1"
</VirtualHost>
<VirtualHost www.example2.dom>
  ServerAdmin webguy@example2.dom
  DocumentRoot "/www/example2"
</VirtualHost>
    


    
    Suppose that you've assigned 192.0.2.1 to
    www.example1.dom and 192.0.2.2 to
    www.example2.dom. Furthermore, suppose that
    example1.dom has control of their own DNS. With this
    config you have put example1.dom into a position where
    they can steal all traffic destined to example2.dom. To
    do so, all they have to do is set www.example1.dom to
    192.0.2.2. Since they control their own DNS you can't stop them
    from pointing the www.example1.dom record wherever they
    wish.
    

    
    Requests coming in to 192.0.2.2 (including all those where
    users typed in URLs of the form
    http://www.example2.dom/whatever) will all be served by
    the example1.dom virtual host. To better understand why
    this happens requires a more in-depth discussion of how httpd
    matches up incoming requests with the virtual host that will
    serve it. A rough document describing this is available.
    
  
    top
    

    

    The "main server" Address
    
    

    
    Name-based
    virtual host support requires httpd to know
    the IP address(es) of the host that httpd
    is running on. To get this address it uses either the global
    ServerName
    (if present) or calls the C function gethostname
    (which should return the same as typing "hostname" at the
    command prompt). Then it performs a DNS lookup on this address.
    At present there is no way to avoid this lookup.
    

    
    If you fear that this lookup might fail because your DNS
    server is down then you can insert the hostname in
    /etc/hosts (where you probably already have it so
    that the machine can boot properly). Then ensure that your
    machine is configured to use /etc/hosts in the
    event that DNS fails. Depending on what OS you are using this
    might be accomplished by editing /etc/resolv.conf,
    or maybe /etc/nsswitch.conf.
    

    
    If your server doesn't have to perform DNS for any other
    reason then you might be able to get away with running httpd
    with the HOSTRESORDER environment variable set to
    "local". This all depends on what OS and resolver libraries you
    are using. It also affects CGIs unless you use
    mod_env to control the environment. It's best
    to consult the man pages or FAQs for your OS.

    Tips to Avoid These Problems
    
    

    
      
      
    • 
        use IP addresses in
        VirtualHost
      
      • 

      
    • 
        use IP addresses in
        Listen
      
      • 

      
    • 
        ensure all virtual hosts have an explicit
        ServerName
      
      • 

      
    • create a <VirtualHost _default_:*>
      server that has no pages to serve
      •

    Çekirdekteki Gelişmeler
    
    
    
    

      
    Authn/Authz
    
      
    Mevcut kimlik doğrulama ve yetkilendirme modüllerinin iç işleyişi
        yeniden düzenlendi. Yeni mod_authn_alias modülü
        (2.3/2.4 sürümlerinde kaldırılmıştır) belli kimlik doğrulama
        yapılandırmalarını büyük oranda basitleştirebilir. Bu değişikliklerin
        kullanıcıları ve modül yazarlarını nasıl etkilediğini öğrenmek için
        modül değişikliklerine ve geliştirici değişikliklerine bakabilirsiniz.
    

      
    Önbellekleme
    
      
    mod_cache, mod_cache_disk ve
        mod_mem_cache (2.3/2.4 sürümlerinde kaldırılmıştır)
        modüllerinde büyük oranda değişikliğe gidilerek bunlar deneysel
        olmaktan çıkarılıp üretim amaçlı modüller haline getirildiler.
        mod_cache_disk tarafından kullanılan disk
        alanının  htcacheclean tarafından
        düzenli aralıklarla temizlenebilmesi sağlandı.
    

      
    Yapılandırma
    
      
    Öntanımlı yapılandırma basitleştirildi ve modüler bir yapıya
        kavuşturuldu. Sık kullanılan ortak özellikleri etkinleştirmekte
        kullanılan yapılandırmalar gruplanarak bunların Apache ile gelmesi ve
        ana sunucu yapılandırılırken yapılandırmaya kolayca eklenebilmesi
        sağlandı.
    

      
    Nazikçe Durdurma
    
      
    prefork, worker ve
        event  MPM’leri artık httpd’yi graceful-stop
        sinyali sayesinde nazikçe durdurabilmektedir.
        httpd programının sonlandırılmasındaki gecikmelere
        karşı bir önlem olarak, isteğe bağlı bir zaman aşımı belirtmeyi
        mümkün kılan GracefulShutdownTimeout yönergesi
        sayesinde sunum sürüyor olsa bile httpd

    Vekil Sunucu
    
      
    Yeni mod_proxy_balancer modülü ile
        mod_proxy için yük dengeleme hizmetleri sağlanmış,
        yeni mod_proxy_ajp modülü ile Apache Tomcat tarafından
        kullanılan Apache JServ Protokolünün 1.3 sürümü için destek
        eklenmiştir.
    

      
    Düzenli İfade Kütüphanesi Güncellemesi
    
      
    Apache, Perl uyumlu düzenli ifade
        kütüphanesinin 5.0 sürümünü (PCRE) içermektedir.
        configure betiğinin --with-pcre
        seçeneği sayesinde httpd programı PCRE destekli

        başlığına veya bir ortam değişkenine dayanarak koşullu olarak
        yerleştirilmesini mümkün kılar ve bunu yaparken 2.0 mimarisindeki

        gelir.
    

      
    Büyük Dosya (>2GB) Desteği
    
      
    httpd artık günümüzün 32 bitlik Unix
        sistemlerinde bulunan 2 GB’lık büyük dosyaları destekleyecek tarzda
        derlenebilmektedir. 2 GB’lık istek gövdelerine destek de ayrıca

    event MPM modülü sürekli bağlantı isteklerinin
        işlenmesi ve bağlantıların kabul edilmesi için ayrı bir evre
        kullanır. Sürekli bağlantı (keepalive) isteklerinin işlenmesi
        geleneksel olarak httpd’nin buna bir worker
        adamasını gerektirirdi. Bu adanmış worker bağlantı
        zaman aşımına uğrayıncaya değin tekrar kullanılamazdı.

    Modül Geliştirici Değişiklikleri
    
    
    
    
      
    APR 1.0 Programlama Arayüzü
    

      
    Apache 2.2’de APR 1.0 API kullanılmıştır.  Kullanımı önerilmeyen
        tüm işlevler ve simgeler APR ve
        APR-Util’den kaldırılmıştır. Ayrıntılar için APR Sitesine bakınız.
    

      
    Authn/Authz
    
      
    Dağıtımla gelen kimlik doğrulama ve yetkilendirme modüllerinin
          isimleri aşağıdaki gibi değiştirildi:
          
      
          
    • mod_auth_*  -> HTTP kimlik doğrulamasını
            gerçekleştiren modüller.
      • 
          
    • mod_authn_* -> Kimlik doğrulamasının artalanına
            destek sağlayan modüller.
      • 
          
    • mod_authz_* -> Yetkilendirmeyi (veya erişimi)
            gerçekleştiren modüller.
      • 
          
    • mod_authnz_* -> Kimlik doğrulama ve
            yetkilendirmeyi birlikte gerçekleştiren modüller.
      • 
          
    
          Yeni kimlik doğrulama artalanının oluşturulmasını büyük oranda
          kolaylaştıran yeni bir kimlik doğrulama artalanı sağlayıcı şeması
          vardır.
    

      
    Bağlantı Hatalarının Günlüklenmesi
    

      
    İstemci bağlantısında ortaya çıkan hataları günlüğe kaydetmek için
        ap_log_cerror isminde yeni bir işlev eklendi. Böyle bir
        durumda günlük kaydı istemcinin IP adresini içermektedir.
    

      
    Deneme Yapılandırma Kancası Eklendi
    

      
    Kullanıcı, httpd’yi sadece -t
        seçeneği ile kullandığı takdirde özel kod icra edilmesini isteyen
        modüllere yardımcı olmak üzere test_config diye yeni bir
        kanca işlev eklendi.
    

      
    Evreli MPM’lerin Yığıt Boyutunun Ayarlanması
    

      
    Tüm evreli MPM’lerin yığıt boyutunu ayarlamak üzere ThreadStackSize isminde yeni bir
        yönerge eklendi. Öntanımlı yığıt boyutunun küçük olduğu platformlarda
        bazı üçüncü parti modüller tarafından buna ihtiyaç duyulmaktadır.
    

      
    Çıktı süzgeçlerinde protokoller
    

      
    Evvelce her süzgeç etkilediğini yanıt başlıklarının doğru olarak

        ap_register_output_filter_protocol veya
        ap_filter_protocol işlevi üzerinden
        mod_filter modülüne devredebilmektedir.
    

      
    İzleme kancası eklendi
    
      
    İzleme kancası, modüllerin ana (tepe) süreçteki sıradan/zamanlanmış
        işlerini yapacak modülleri etkinleştirir.
    

      
    Düzenli ifade programlama aryüzü değişti
    

      
    pcreposix.h başlık dosyası artık yok; yerine
        ap_regex.h dosyası geçti. Eski başlık dosyasınca ifade
        olunan POSIX.2 regex.h gerçeklenimi şimdi
        ap_ isim alanı altında ap_regex.h başlık
        dosyasındadır. regcomp, regexec gibi
        işlevlerin yerine de artık ap_regcomp,
        ap_regexec işlevleri geçerlidir.
    

      
    DBD Arayüzü (SQL Veritabanı API)
    

      
    Apache 1.x ve 2.0’da, modüller, SQL veritabanlarını kendileri
        yönetebilmek için sorumluluğu alacak bir SQL artalanına ihtiyaç
        duymaktadır. Her biri kendi bağlantısına sahip bir sürü modül
        olduğunda bu yöntem çok verimsiz olabilmektedir.
    

      
    Apache 2.1 ve sonrasında veritabanı bağlantılarını (evreli olsun
        olmasın MPM’lerin eniyilenmiş stratejileri dahil) yönetmek için
        ap_dbd arayüzü kullanılmıştır. APR 1.2 ve sonrasında ise
        veritabanı ile etkileşim apr_dbd arayüzüyle
        sağlanmıştır.
    

      
    Yeni modüllerin tüm SQL veritabanı işlemlerinde bu arayüzü
        kullanmaları ÖNERİlir.  Mevcut uygulamaların uygulanabildiği takdirde
        hem kullanıcılarına önerilen bir seçenek olarak hem de şeffaf olarak
        kullanmak üzere kendilerini güncellemeleri ÖNERİir.

    Dieses Dokument umfasst das Beenden und Neustarten des
    Apache auf Unix-ähnlichen Systemen. Anwender von Windows NT, 2000
    und XP sollten Betreiben
    des Apache als Dienst lesen, während hingegen Anwender von
    Windows 9x sowie ME Betreiben
    des Apache als Konsolenanwendung lesen sollten, um mehr Informationen
    zur Handhabung des Apache auf diesen Systemen zu erhalten.

    Einleitung
    

    
    Um den Apache zu stoppen oder neu zu starten, müssen Sie
    ein Signal an den laufenden httpd-Prozess senden. Es gibt
    zwei Möglichkeiten, diese Signale zu senden. Zum einen können
    Sie den Unix-Befehl kill verwenden, um den Prozessen
    direkt Signale zu senden. Sie werden feststellen, dass auf Ihrem
    System mehrere httpd-Programme laufen. Sie sollten
    jedoch nicht jedem dieser Prozesse ein Signal senden, sondern nur dem
    Elternprozess, dessen PID im PidFile steht. Das heißt, Sie
    sollten es niemals nötig haben, einem anderen Prozess, als dem
    Elternprozess, ein Signal zu senden. Es gibt drei Signale, die Sie an den
    Elternprozess senden können: TERM,
    HUP und
    USR1, die nachfolgend beschrieben
    werden.
    

    
    Um dem Elternprozess ein Signal zu senden, verwenden Sie einen
    Befehl wie z.B.:
    

    
    kill -TERM `cat /usr/local/apache2/logs/httpd.pid`
    

    
    Die zweite Methode, dem httpd-Prozess zu
    signalisieren, ist die Verwendung der -k-Befehlszeilenoptionen
    stop, restart und graceful, wie
    unten beschrieben. Dies sind Argumente des httpd-Programms, es wird jedoch
    empfohlen, sie unter Verwendung des Steuerskripts apachectl zu senden, welches diese
    an httpd durchreicht.
    

    
    Nachdem Sie httpd signalisiert haben, können Sie
    dessen Fortschritt beobachten, indem Sie eingeben:
    

    
    tail -f /usr/local/apache2/logs/error_log
    

    
    Passen Sie diese Beispiele entsprechend Ihren ServerRoot- und PidFile-Einstellungen an.
    

    top
    

    

    Beenden
    

    
    Signal: TERM
    
      
    apachectl -k stop
    
    
    

    
    Das Senden des TERM- oder stop-Signals an
    den Elternprozess veranlasst diesen, sofort zu versuchen, alle seine
    Kindprozesse zu beenden. Es kann einige Sekunden dauern, bis alle
    Kindprozesse komplett beendet sind. Danach beendet sich der Elternprozess
    selbst. Alle gerade bearbeiteten Anfragen werden abgebrochen.
    Es werden keine weiteren Anfragen mehr bedient.
    

    top
    

    

    Unterbrechungsfreier Neustart
    

    
    Signal: USR1
    
      
    apachectl -k graceful
    
    
    

    
    Das USR1- oder graceful-Signal
    veranlasst den Elternprozess, die Kinder anzuweisen, sich
    nach Abschluß ihrer momentanen bearbeiteten Anfrage zu beenden
    (oder sich sofort zu beenden, wenn sie gerade keine Anfrage bedienen).
    Der Elternprozess liest seine Konfigurationsdateien erneut ein und
    öffnet seine Logdateien neu. Wenn ein Kindprozess stirbt,
    ersetzt der Elternprozess ihn durch ein Kind der neuen
    Konfigurations-Generation. Dieses beginnt sofort damit,
    neue Anfragen zu bedienen.
    

    
    Auf bestimmten Plattformen, welche kein USR1
    für einen unterbrechungsfreien Neustart erlauben, kann ein
    alternatives Signal verwendet werden (wie z.B.
    WINCH). Der Befehl apachectl graceful
    sendet das jeweils richtige Signal für Ihre Platform.
    

    
    Der Code ist dafür ausgelegt, stets die MPM-Direktiven
    zur Prozesssteuerung zu beachten, so dass die Anzahl der Prozesse
    und Threads, die zur Bedienung der Clients bereitstehen, während
    des Neustarts auf die entsprechenden Werte gesetzt werden.
    Weiterhin wird StartServers
    auf folgende Art und Weise interpretiert: Wenn nach einer Sekunde
    nicht mindestens StartServers
    neue Kindprozesse erstellt wurden, dann werden, um den Durchsatz zu
    beschleunigen, entsprechend weitere erstellt. Auf diese Weise versucht
    der Code sowohl die Anzahl der Kinder entsprechend der Serverlast
    anzupassen als auch Ihre Wünsche hinsichtlich des Parameters
    StartServers zu
    berücksichtigen.
    

    
    Benutzer von mod_status werden feststellen,
    dass die Serverstatistiken nicht auf Null
    zurückgesetzt werden, wenn ein USR1 gesendet
    wurde. Der Code wurde so geschrieben, dass sowohl die Zeit minimiert
    wird, in der der Server nicht in der Lage ist, neue Anfragen zu
    bedienen (diese werden vom Betriebssystem in eine Warteschlange
    gestellt, so dass sie auf keinen Fall verloren gehen) als auch
    Ihre Parameter zur Feinabstimmung berücksichtigt werden.
    Um dies zu erreichen, muss die Statustabelle (Scoreboard),
    die dazu verwendet wird, alle Kinder über mehrere Generationen
    zu verfolgen, erhalten bleiben.
    

    
    Das Statusmodul benutzt außerdem ein G, um
    diejenigen Kinder zu kennzeichen, die noch immer Anfragen bedienen,
    welche gestartet wurden, bevor ein unterbrechungsfreier Neustart
    veranlaßt wurde.
    

    
    Derzeit gibt es keine Möglichkeit für ein
    Log-Rotationsskript, das USR1 verwendet, sicher
    festzustellen, dass alle Kinder, die in ein vor dem Neustart
    geöffnetes Log schreiben, beendet sind. Wir schlagen vor, dass
    Sie nach dem Senden des Signals USR1 eine angemessene
    Zeitspanne warten, bevor Sie das alte Log anfassen. Wenn beispielsweise
    die meisten Ihrer Zugriffe bei Benutzern mit niedriger Bandbreite
    weniger als 10 Minuten für eine vollständige Antwort
    benötigen, dann könnten Sie 15 Minuten warten, bevor Sie auf
    das alte Log zugreifen.
    

    
    Wenn Ihre Konfigurationsdatei Fehler enthält, während
    Sie einen Neustart anweisen, dann wird Ihr Elternprozess nicht neu starten,
    sondern sich mit einem Fehler beenden. Im Falle eines unterbrechungsfreien
    Neustarts läßt er die Kinder weiterlaufen, wenn er sich beendet.
    (Dies sind die Kinder, die sich "sanft beenden", indem sie ihre letzte
    Anfrage erledigen.) Das verursacht Probleme, wenn Sie versuchen,
    den Server neu zu starten -- er ist nicht in der Lage, sich an die Ports zu
    binden, an denen er lauschen soll. Bevor Sie einen Neustart
    durchführen, können Sie die Syntax der Konfigurationsdateien
    mit dem Befehlszeilenargument -t überprüfen
    (siehe auch httpd). Das garantiert
    allerdings nicht, dass der Server korrekt starten wird. Um sowohl die
    Syntax als auch die Semantik der Konfigurationsdateien zu prüfen,
    können Sie versuchen, httpd als nicht-root-Benutzer
    zu starten. Wenn dabei keine Fehler auftreten, wird er versuchen, seine
    Sockets und Logdateien zu öffnen und fehlschlagen, da er nicht root
    ist (oder weil sich der gegenwärtig laufende httpd
    bereits diese Ports gebunden hat). Wenn er aus einem anderen Grund
    fehlschlägt, dann liegt wahrscheinlich ein Konfigurationsfehler vor.
    Der Fehler sollte behoben werden, bevor der unterbrechungsfreie Neustart
    angewiesen wird.

    Neustarten
    

    
    Signal: HUP
    
      
    apachectl -k restart
    
    
    

    
    Das Senden des Signals HUP oder restart
    veranlaßt den Elternprozess, wie bei TERM alle seine
    Kinder zu beenden. Der Elternprozess beendet sich jedoch nicht. Er liest
    seine Konfigurationsdateien neu ein und öffnet alle Logdateien
    erneut. Dann erzeugt er einen neuen Satz Kindprozesse und setzt die
    Bedienung von Zugriffen fort.
    

    
    Benutzer von mod_status werden feststellen, dass
    die Serverstatistiken auf Null gesetzt werden, wenn ein HUP
    gesendet wurde.
    

    
    Wenn Ihre Konfigurationsdatei einen Fehler enthält,
    während Sie einen Neustart anweisen, dann wird Ihr Elternprozess
    nicht neu starten, sondern sich mit einem Fehler beenden. Lesen Sie oben,
    wie Sie das vermeiden können.

    Anhang: Signale und Wettkampfsituationen
    

    
    Vor der Version 1.2b9 des Apache existierten verschiedene
    Wettkampfsituationen (race conditions), die den Neustart und
    die Signale beeinflußt haben. (Einfach erklärt ist eine
    Wettkampfsituation ein zeitabhängiges Problem - wenn
    etwas zum falschen Zeitpunkt erfolgt oder Dinge in der falschen
    Reihenfolge passieren, ist unerwartetes Verhalten die Folge. Wenn die
    gleichen Dinge zur richtigen Zeit geschehen, funktioniert alles korrekt.)
    Bei Architekturen mit dem "richtigen" Funktionsumfang
    haben wir so viele eliminiert wie wir nur konnten. Dennoch
    sollte beachtet werden, dass noch immer Wettkampfsituationen auf
    bestimmten Architekturen existieren.
    

    
    Bei Architekturen, die ein ScoreBoardFile auf Platte verwenden,
    besteht die Gefahr, dass die Statustabelle beschädigt wird.
    Das kann zu "bind: Address already in use" ("bind: Adresse wird
    bereits verwendet", nach einem HUP) oder "long lost
    child came home!" ("Der verlorene Sohn ist heimgekehrt", nach einem
    USR1) führen. Ersteres ist ein schwerer Fehler,
    wärend letzteres lediglich bewirkt, dass der Server einen Eintrag
    in der Statustabelle verliert. So kann es ratsam sein, unterbrechungsfreie
    Neustarts zusammen mit einem gelegentlichen harten Neustart zu verwenden.
    Diese Probleme lassen sich nur sehr schwer umgehen, aber
    glücklicherweise benötigen die meisten Architekturen keine
    Statustabelle in Form einer Datei. Bitte lesen Sie für Architekturen,
    die sie benötigen, die Dokumentation zu ScoreBoardFile.
    

    
    Alle Architekturen haben in jedem Kindprozess eine kleine
    Wettkampfsituation, welche die zweite und nachfolgende Anfragen
    einer persistenten HTTP-Verbindung (KeepAlive) umfaßt. Der Prozess
    kann nach dem Lesen der Anfragezeile aber vor dem Lesen der Anfrage-Header
    enden. Es existiert eine Korrektur, die für 1.2 zu spät kam.
    Theoretisch sollte das kein Problem darstellen, da
    der KeepAlive-Client derartige Ereignisse aufgrund von
    Netzwerk-Latenzzeiten und Auszeiten des Servers erwarten sollte.
    In der Praxis scheint keiner von beiden beeinflußt zu werden
    -- in einem Testfall wurde der Server zwanzig mal
    pro Sekunde neu gestartet, während Clients das Angebot abgegrast
    haben, ohne kaputte Bilder oder leere Dokumente zu erhalten.

    Fichiers de configuration principaux
    
    
    
    Modules ApparentésDirectives Apparentées
    

    
    La configuration du serveur HTTP Apache est effectuée en plaçant des directives dans des fichiers de
    configuration au format texte. Le fichier de configuration principal se nomme
    en général
    httpd.conf. La localisation de ce fichier est définie
    à la compilation, mais peut être redéfinie à l'aide de l'option
    de ligne de commande -f. En outre, d'autres fichiers de
    configuration peuvent être ajoutés à l'aide de la directive
    Include, et des caractères de
    remplacement
    peuvent être utilisés pour inclure de nombreux fichiers de configuration.
    Des directives de tous types peuvent être placées dans chacun de ces fichiers
    de configuration.  Les modifications dans les fichiers de configuration
    principaux ne sont prises en compte par httpd que lorsque le serveur
    est démarré ou redémarré.
    

    
    Le serveur lit aussi un fichier contenant les types de document mime;
    ce fichier est défini par la directive TypesConfig,
    et se nomme mime.types par défaut.
    
  
    top
    

    

    Syntaxe des fichiers de configuration
    
    

    
    Les fichiers de configuration de httpd contiennent une directive
    par ligne.
    On peut utiliser l'anti-slash "\" comme dernier caractère d'une ligne
    pour indiquer que la directive continue à la ligne suivante.
    Il ne doit y avoir aucun caractère ni espace entre l'anti-slash et
    la fin de la ligne.
    

    
    Les arguments des directives sont séparés les uns des autres par
    des espaces. Si un argument contient des espaces, il doit être
    entouré de guillemets.
    

    
    Les directives dans les fichiers de configuration ne sont pas
    sensibles à la casse, mais leurs arguments le sont souvent. Les lignes
    qui débutent par le caractère "#" sont interprétées comme des
    commentaires, et sont ignorées. Les commentaires ne doivent
    pas apparaître sur la même ligne qu'une directive
    de configuration. Les espaces précédant une directive
    sont ignorés; vous pouvez par conséquent indenter les directives
    afin d'améliorer la lisibilité. Les lignes vides sont
    aussi ignorées.
    

    
    Les valeurs des variables d'environnement ou des variables
    définies via la directive Define peuvent être utilisées dans le
    fichier de configuration en utilisant la syntaxe
    ${VAR}. Si "VAR" est le nom d'une variable valide, la
    valeur de la variable est alors substituée à la chaîne
    ${VAR}, et le processus de lecture du fichier de
    configuration continue comme si la chaîne correspondant à la valeur
    de la variable s'y était trouvée littéralement. Les variables définies
    via la directive Define
    l'emportent sur les autres variables d'environnement du shell. Si la
    variable "VAR" n'est pas trouvée, la chaîne ${VAR}
    n'est pas modifiée, et un avertissement est enregistré dans le
    journal. Le caractère ":" est interdit dans les noms de variables
    afin d'éviter tout conflit avec la syntaxe de la directive RewriteMap.
    

    
    Seules les variables d'environnement du shell définies avant le démarrage
    du serveur peuvent être utilisées en extension.
    Les variables d'environnement
    définies dans le fichier de configuration lui-même, par exemple avec SetEnv, prennent effet trop tard pour
    pouvoir être utilisées en extension au sein du fichier de
    configuration.
    

    
    La longueur maximale d'une ligne dans un fichier de configuration
    normal, après substitution des variables et fusion des lignes
    interrompues, est approximativement de 16 Mo. Dans les fichiers .htaccess, la longueur
    maximale est de 8190 caractères.
    

    
    Vous pouvez vérifier l'absence d'erreurs de syntaxe dans vos fichiers
    de configuration sans démarrer le serveur à l'aide de la commande
    apachectl configtest ou de l'option de ligne de commande
    -t.
    

    
    Vous pouvez utiliser la définition -DDUMP_CONFIG de
    mod_info pour afficher la configuration avec tous
    les fichiers inclus et les variables d'environnement évaluées, tous
    les commentaires et les sections <IfDefine> et <IfModule> non actives ayant
    été supprimés. Cependant, la sortie ne reflète
    pas les fusions ou écrasements pouvant intervenir en cas de
    définitions multiples de directives.

    Modules
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    httpd est un serveur modulaire. Ceci implique que seules les
    fonctionnalités les plus courantes sont incluses dans le serveur de base.
    Les fonctionnalités étendues sont fournies à l'aide de modules qui peuvent être chargés dans httpd.
    Par défaut, un jeu de modules de base est inclus dans le
    serveur à la compilation. Si le serveur est compilé de façon à utiliser
    les modules chargés dynamiquement,
    alors les modules peuvent être compilés séparément et chargés à
    n'importe quel moment à l'aide de la directive
    LoadModule.
    Dans le cas contraire, httpd doit être recompilé pour ajouter ou
    supprimer des modules.
    Les directives de configuration peuvent être incluses de manière
    conditionnelle selon la présence ou l'absence d'un module particulier
    en les plaçant dans un bloc <IfModule>.
    

    
    Pour voir quels modules ont été compilés avec le serveur,
    vous pouvez utiliser l'option de ligne de commande -l.
    
  
    top
    

    

    Portée des directives
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    Les directives placées dans les fichiers de configuration principaux
    s'appliquent au serveur dans son ensemble. Si vous souhaitez modifier la
    configuration d'une partie du serveur seulement, vous pouvez limiter la
    portée de vos directives en les plaçant dans une section
    <Directory>, <DirectoryMatch>, <Files>, <FilesMatch>, <Location>, ou <LocationMatch>.
    Ces sections limitent le champ d'application des directives qu'elles
    contiennent à des URls ou des portions du système de fichiers particulières.
    Elles peuvent aussi être imbriquées, ce qui permet
    une configuration très fine.
    

    
    httpd peut servir simultanément de nombreux sites web au travers des
    Hôtes Virtuels. La portée des directives peut ainsi
    être limitée en les plaçant dans des sections
    <VirtualHost>,
    afin qu'elles ne s'appliquent qu'aux requêtes
    pour un site web particulier.
    

    
    Bien que la plupart des directives puissent être placées dans
    chacune de ces sections, certaines d'entre elles n'ont aucun sens
    dans certains contextes.
    Par exemple, les directives qui contrôlent la création des processus
    n'ont de sens que dans le contexte du serveur principal. Pour déterminer
    quelles directives peuvent être placées dans quelles sections, consultez
    le Contexte de la
    directive. Pour plus d'informations, nous fournissons des détails dans
    Comment fonctionnent les sections Directory,
    Location et Files.

    Fichiers .htaccess
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    httpd permet la gestion décentralisée de la configuration
    via des fichiers spéciaux placés dans l'arborescence du site web.
    Ces fichiers spéciaux se nomment en général .htaccess,
    mais tout autre nom peut être spécifié à l'aide de la directive
    AccessFileName.
    Les directives placées dans les fichiers .htaccess
    s'appliquent au répertoire dans lequel vous avez placé le fichier,
    ainsi qu'à tous ses sous-répertoires.
    La syntaxe des fichiers .htaccess est la même que celle
    des fichiers de configuration principaux. Comme les fichiers
    .htaccess sont lus à chaque requête, les modifications de
    ces fichiers prennent effet immédiatement.
    

    
    Pour déterminer quelles directives peuvent être placées
    dans les fichiers .htaccess, consultez le
    Contexte de la
    directive. L'administrateur du serveur peut contrôler quelles
    directives peuvent être placées dans les fichiers
    .htaccess en définissant la directive
    AllowOverride
    dans les fichiers de configuration principaux.
    

    
    Pour plus d'informations sur les fichiers .htaccess,
    se référer au tutoriel .htaccess.

    Ce document décrit ce qu'est un Module Multi-Processus, ainsi
que la manière dont ces modules sont utilisés par le serveur HTTP Apache.
    

    


    top
    

    

    Introduction
    

    
    La conception du serveur HTTP Apache en fait un serveur web puissant et
    flexible pouvant fonctionner sur une très grande variété de
    plateformes et toute une gamme d'environnements différents. Plateformes
    différentes et environnements différents signifient souvent fonctionnalités
    différentes, ou utilisation de différentes méthodes pour
    implémenter la même fonctionnalité le plus efficacement possible.
    Apache httpd s'est toujours accomodé d'une grande variété d'environnements
    grâce à sa conception modulaire. Cette conception autorise le webmaster
    à choisir quelles fonctionnalités seront incluses
    dans le serveur en sélectionnant les modules à charger soit à la
    compilation, soit à l'exécution.
    

    
    Le serveur HTTP Apache 2.0 a étendu cette conception modulaire aux
    fonctions les plus
    élémentaires d'un serveur web. Le serveur est fourni avec une variété de
    Modules Multi-Processus (MPMs) qui
    sont responsables de l'association aux ports réseau de la machine,
    acceptent les requêtes, et se chargent de répartir ces dernières
    entre les différents processus enfants.
    

    
    L'extension de la conception modulaire à ce niveau du serveur
    comporte deux avantages importants :
    

    
      
      
    • Apache httpd peut supporter plus proprement et efficacement une grande
      variété de systèmes d'exploitation. En particulier, la version Windows
      du serveur est maintenant beaucoup plus efficace, depuis que
      mpm_winnt peut utiliser les fonctionnalités réseau
      natives à la place de la couche POSIX utilisée par
      Apache httpd 1.3. Cet avantage s'étend aussi aux systèmes d'exploitation
      qui implémentent des MPMs spécialisés.
      • 

      
    • le serveur est plus à même de répondre aux besoins d'un site
      particulier. Par exemple, les sites qui sont très sollicités peuvent
      utiliser un MPM threadé comme
      worker ou event, tandis que les sites
      qui privilégient la stabilité ou la compatibilité avec des logiciels
      plus anciens peuvent utiliser un module comme
      prefork.
      • 
    
    

    
    Du point de vue de l'utilisateur, les MPMs ne sont pas différents des
    autres modules Apache httpd. La principale différence réside dans le fait qu'un
    et un seul MPM à la fois doit être chargé
    lorsque le serveur s'exécute. La liste des
    MPMs disponibles est fournie dans l'index des
    modules.
    


    top
    

    

    MPM par défaut
    


    La table suivante fournit la liste des MPMs par défaut pour divers
systèmes d'exploitation.  Il s'agit du MPM qui sera utilisé si
vous n'en spécifiez pas un autre à la compilation.
    


    Netwarempm_netware
    

    OS/2mpmt_os2
    

    Unixprefork, worker,
ou event, selon les possibilités de la plate-forme
    

    Windowsmpm_winnt
    

    


    Ici, 'Unix' sous-entend les systèmes d'exploitation de type
Unix, comme Linux, BSD, Solaris, Mac OS X, etc...
    


    Dans le cas des systèmes d'exploitation de type Unix, le choix du MPM
à installer est orienté par deux questions :
    

    1. Est-ce que le système supporte les threads ?
    

    2. Est-ce que le système supporte le polling thread-safe (et en
particulier les fonctions kqueue et epoll) ?
    


    Si la réponse aux deux questions est 'oui', le MPM par défaut sera
event.
    


    Si la réponse à la première question est 'oui', et la réponse à la
deuxième 'non', le MPM par défaut sera worker.
    


    Si la réponse aux deux questions est 'non', le MPM par défaut sera
prefork.
    


    En pratique, cela signifie que le MPM par défaut sera presque
toujours event car tous les systèmes d'exploitation
modernes satisfont aux deux conditions.

    Compiler un module MPM en tant que module
statique
    

    
    Les modules MPM peuvent être compilés en tant que modules
statiques sur toutes les plates-formes. A la compilation d'Apache, un
seul module MPM doit être choisi pour être compilé et lié avec le
serveur. La recompilation du serveur sera donc nécessaire si vous
souhaitez changer de module MPM.
    

    
    Pour choisir un module MPM autre que le MPM par défaut,
    utiliser l'argument
      --with-mpm=NOM du script
      configure. NOM est le nom
      du MPM désiré.
    

    
    Une fois le serveur compilé, il est possible de savoir quel MPM
    a été choisi à l'aide de la commande ./httpd -l.
    Cette commande fournit la liste de tous les modules compilés
    avec le serveur, y compris le MPM.
    


    top
    

    

    Compiler un module MPM en tant que module
DSO (Dynamic Shared Object)
    

    
    Sous Unix et les plates-formes similaires, les modules MPM
    peuvent être compilés en tant que modules DSO et chargés
    dynamiquement dans le serveur comme tout module DSO. Compiler les
    modules MPM en tant que modules DSO permet de changer de MPM en
    modifiant la directive LoadModule concernée, sans avoir à
    recompiler le serveur.
    

    
    LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
    


    
    Toute tentative de charger plusieurs modules MPM via la directive
    LoadModule empêchera le
    serveur de démarrer et affichera l'erreur suivante :
    

    
    AH00534: httpd: Configuration error: More than one MPM
    loaded.
    

    
    Cette fonctionnalité est activée via l'option
    --enable-mpms-shared du script
    configure. Si on ajoute l'argument
    all, tous les modules MPM disponibles sur la
    plate-forme considérée seront installés. Cet argument peut aussi
    contenir une liste de modules MPM à installer.
    

    
    Le module MPM par défaut, sélectionné automatiquement ou spécifié
    via l'option --with-mpm du script
    configure, sera chargé via une directive
    LoadModule du fichier de
    configuration du serveur généré. Pour choisir un autre module MPM,
    vous devrez donc modifier cette directive

    動作
    
    

    
    古い動作
    
      

      
    NCSA httpd 1.3 は、古くて退屈なエラー/問題メッセージを
      返していました。それはしばしばユーザには無意味であり、
      またそれを発生させた原因を記録する方法も提供していませんでした。
    
    

    
    新しい動作
    
      

        
      
          
    1. NCSA のハードコードされたメッセージの代わりに
          他のテキストを表示
      2. 

          
    2. ローカルの URL にリダイレクト
      3. 

          
    3. 外部の URL にリダイレクト
      4. 
        
    

        
    するようにサーバを設定できます。
    

        
    別の URL にリダイレクトすることは役に立ちますが、
        それは説明をしたり、より明確に誤り/問題を記録したりするために
        何か情報を伝えられるときに限ります。
    

        
    これを実現するために、 Apache は新しく CGI のような環境変数を
        定義します:
    

        
    
          REDIRECT_HTTP_ACCEPT=*/*, image/gif,
          image/x-xbitmap, image/jpeg
    
           REDIRECT_HTTP_USER_AGENT=Mozilla/1.1b2 (X11; I; HP-UX
          A.09.05 9000/712)
    
           REDIRECT_PATH=.:/bin:/usr/local/bin:/etc
    
           REDIRECT_QUERY_STRING=
    
           REDIRECT_REMOTE_ADDR=121.345.78.123
    
           REDIRECT_REMOTE_HOST=ooh.ahhh.com
    
           REDIRECT_SERVER_NAME=crash.bang.edu
    
           REDIRECT_SERVER_PORT=80
    
           REDIRECT_SERVER_SOFTWARE=Apache/0.8.15
    
           REDIRECT_URL=/cgi-bin/buggy.pl
        
    

        
    頭に付く REDIRECT_ に注目してください。
    

        
    少なくとも REDIRECT_URL と
        REDIRECT_QUERY_STRING は新しい URL (CGI スクリプトか
        CGI インクルードであると仮定されます) に渡されます。
        他の変数は、エラーや問題が起きる前に存在した場合にだけ存在します。
        もしあなたの設定した ErrorDocument が 外部リダイレクト
        (すなわち、http: 
        のような体系名から始まるすべてのもの。たとえ同じホストを指していても)
        ならば、これらはまったく設定されません。
    
    
  
    top
    

    

    設定
    
    

    
    AllowOverride が適切に設定されていれば、
    .htaccess ファイルで ErrorDocument
    を使用することができます。
    

        
    ここに、いくつかの例を挙げます。
    

    
    
      ErrorDocument 500 /cgi-bin/crash-recover 
    
      ErrorDocument 500 "Sorry, our script crashed. Oh dear" 
    
      ErrorDocument 500 http://xxx/ 
    
      ErrorDocument 404 /Lame_excuses/not_found.html 
    
      ErrorDocument 401 /Subscription/how_to_subscribe.html
    
    

    
    構文
    

    
    
      ErrorDocument <3-digit-code> <action>
    
    

        
    action (動作) は、下記のいずれかです
    

        
      
          
    1. 表示するテキスト。テキストは引用符 (") で囲んで指定します。
      2. 

          
    2. リダイレクト先の外部 URL 
      3. 

          
    3. リダイレクト先のローカル URL 
      4. 
        
    
  
    top
    

    

    カスタムエラーレスポンスとリダイレクト
    
    

      
    スクリプト/SSI に追加の環境変数が利用可能になるように、
      リダイレクトされた URL に対する Apache の動作が変更されました。
    

    
    古い動作
    
      

      
    リダイレクトされたスクリプトは標準の CGI
      環境変数を利用可能でした。しかし、どこからリダイレクト
      されたかの情報は提供されていませんでした。
    
    

    
    新しい動作
    
      

      
    リダイレクトされた先のスクリプトが使用可能なように、
      新しいたくさんの環境変数が初期化されます。新しい変数は、それぞれ
      REDIRECT_ で始まります。
      REDIRECT_ で始まる環境変数はリダイレクトされる前に存在していた
      CGI 環境変数の頭に REDIRECT_ を付けて作成されます。
      すなわち、HTTP_USER_AGENT は 
      REDIRECT_HTTP_USER_AGENT になります。
      これらの新しい変数に加えて、Apache は、
      スクリプトがリダイレクト元のトレースを助けるために
      REDIRECT_URL と REDIRECT_STATUS
      を定義します。アクセスログには元の URL とリダイレクトされた URL
      の両方が記録されます。
    

    
    ErrorDocument が CGI スクリプトへのローカルリダイレクトを
    指定している場合は、それを起動することになったエラーの状態を
    クライアントまで確実に伝えるために "Status:" 
    ヘッダを含むべきです。例えば、ErrorDocument 用の Perl
    スクリプトは以下のようなものを含むかもしれません。
    
    

      
    
        ... 
    
        print  "Content-type: text/html\n"; 
    
        printf "Status: %s Condition Intercepted\n", $ENV{"REDIRECT_STATUS"}; 
    
        ...
      
    

    
    スクリプトが 404 Not Found のような
    特定のエラーコンディションを扱うためだけに使われる場合は、
    代わりに特定のコードとエラーテキストを使用することができます。

    Este documento describe el uso de los Handlers en Apache.
    
  
    


    top
    

    

    ¿Qué es un Handler?
    
    
    
    Módulos RelacionadosDirectivas Relacionadas
    


    
    Un "handler" es una representación interna de Apache de
    una acción que se va a ejecutar cuando hay una llamada a un
    fichero. Generalmente, los ficheros tienen handlers
    implícitos, basados en el tipo de fichero de que se
    trata. Normalmente, todos los ficheros son simplemente servidos
    por el servidor, pero algunos tipos de ficheros se tratan de forma
    diferente.
    

    
    Handlers pueden ser usados de manera explicita,
     basándose en la extensión del fichero o en
    la ubicación en la que esté, se pueden especificar handlers
    sin tener en cuenta el tipo de fichero que se trate. Esto es
    una ventaja por dos razones. Primero, es una solución
    más elegante. Segundo, porque a un fichero se le pueden
    asignar tanto un tipo como un handler. (Consulte
    también la sección Ficheros y extensiones
    múltiples.)
    

    
    Los Handlers pueden tanto ser compilados con el servidor
    como incluidos en un módulo, o añadidos con la
    directiva Action. Los
    handlers que vienen incluidos en el core con el servidor de la distribución
    estándar de Apache son:
    

    
      
      
    • default-handler: Envía el fichero
      usando el default_handler(), que es el handler
      usado por defecto para tratar contenido
      estático. (core)
      • 

      
    • send-as-is: Envía el fichero con
      cabeceras HTTP tal y como es. (mod_asis)
      • 

      
    • cgi-script: Trata el fichero como un sript
      CGI. (mod_cgi)
      • 

      
    • imap-file: Trata el fichero como un mapa de
      imágenes. (mod_imagemap)
      • 

      
    • server-info: Extrae la información de
      configuración del
      servidor. (mod_info)
      • 

      
    • server-status: Extrae el informe del estado
      del servidor. (mod_status)
      • 

      
    • type-map: Trata el fichero como una
      correspondencia de tipos para la negociación de contenidos.
      (mod_negotiation)
      •  
    
     
  
    top
    

    

    Ejemplos
     
      

      
    Modificar contenido estático usando un script
      CGI
    
      

      
    Las siguientes directivas hacen que cuando haya una
      petición de ficheros con la extensión
      html se lance el script CGI
      footer.pl.
    

      
    
        Action add-footer /cgi-bin/footer.pl
    
        AddHandler add-footer .html
      
    

      
    En este caso, el script CGI es el responsable de enviar el
      documento originalmente solicitado (contenido en la variable de
      entorno PATH_TRANSLATED) y de hacer cualquier
      modificación o añadido deseado.
    

    
    
    Archivos con cabeceras HTTP
    
      

      
    Las siguientes directivas activan el handler
      send-as-is, que se usa para ficheros que contienen
      sus propias cabeceras HTTP. Todos los archivos en el directorio
      /web/htdocs/asis/ serán procesados por el
      handler send-as-is, sin tener en cuenta su
      extension.
    

      
    <Directory "/web/htdocs/asis">
    SetHandler send-as-is
</Directory>
    


    
  
    top
    

    

    Nota para programadores
    
    

    
    Para implementar las funcionalidades de los handlers, se ha
    hecho un añadido a la API de
    Apache que puede que quiera usar. Para ser más
    específicos, se ha añadido un nuevo registro a la
    estructura request_rec:
    

    
    char *handler
    


    
    Si quiere que su módulo llame a un handler , solo tiene
    que añadir r->handler al nombre del handler
    en cualquier momento antes de la fase invoke_handler
    de la petición. Los handlers se implementan siempre como se
    hacía antes, aunque usando el nombre del handler en vez de un
    tipo de contenido. Aunque no es de obligado cumplimiento, la
    convención de nombres para los handlers es que se usen
    palabras separadas por guiones, sin barras, de manera que no se
    invada el media type name-space.

    Apache 2’de Süzme İşlemi
     
    
    İlgili Modüllerİlgili Yönergeler
    

    
    Apache 2.0 ve sonrasında mevcut olan Süzgeç Zinciri, uygulamaların
      nereden geldiğine bakmaksızın gelen ve giden verileri oldukça esnek ve
      yapılandırılabilir tarzda işlemesini mümkün kılar. Böylece, gelen veriyi
      bir takım ön işlemlerden geçirebilir, giden veriyi de son bir defa bazı
      işlemlere sokabiliriz. Bu işlem temel olarak geleneksel istek işleme
      aşamalarından bağımsızdır.
    

    
    
      Süzgeçler, İstek işleme eksenine dik bir veri eksenine peş peşe  yerleştirilebilir.
    
    

    
    Standard Apache dağıtımıyla gelen süzgeç uygulamalarından bazıları:
    

    
      
      
    • mod_include, sunucu taraflı içerik yerleştirmeyi
      gerçekler.
      • 
      
    • mod_ssl, SSL şifrelemesini gerçekler (https).
      • 
      
    • mod_deflate, veri sıkıştırma/açma işlemlerini
      çalışma anında gerçekleştirir.
      • 
      
    • mod_charset_lite, karakter kümeleri arasında
      dönüşümü gerçekleştirir.
      • 
      
    • mod_ext_filter, harici bir yazılımı bir süzgeç
      olarak çalıştırır.
      • 
    
    

    
    Apache, bunlardan başka, bayt dizilerinin elde edilmesi ve içeriğin
      bölünmesi gibi işlemleri gerçekleştirmek için bir takım dahili süzgeçler
      de  kullanabilir.
    

    
    Üçüncü parti süzgeç modülleri tarafından gerçeklenmiş
      modüllerden bazılarının uygulama alanları:
    

    
      
      
    • HTML ve XML belgelerin işlenmesi ve yazılması
      • 
      
    • XSLT dönüşümleri ve XInclude’lar
      • 
      
    • XML İsim-alanı desteği
      • 
      
    • HTML Formlarının çözümlenmesi ve sunucuya dosya yükleme
      • 
      
    • Resim işleme
      • 
      
    • PHP betikleri gibi zararlı olabilecek uygulamalardan korunma
      • 
      
    • Metin düzenleme ve arama işlemleri
      • 
    
    
  
    top
    

    

    Akıllı Süzme
    
    
    
      Farklı süzgeç üreticilerinin uygulamaları istek işlemenin durumuna  bağlı olarak akıllıca uygulanabilir.
    
    

    
    mod_filter, Apache 2.1 ve sonrasında mevcut olup,
      süzgeç zincirinin çalışma anında devingen olarak yapılandırılabilmesini
      mümkün kılar. Böylece, örneğin, bir vekili, özgün sunucunun ne
      göndereceğini bilmeden HTML’yi bir HTML süzgeciyle yazmaya ve JPEG
      resimleri tamamen farklı bir süzgeçten geçirmeye ayarlayabilirsiniz. Bu,
      asıl içeriğe bağlı olarak çalışma anında içeriği farklı içerik
      sağlayıcılara dağıtan bir süzgeç düzeneği kullanılarak çalışır. Bir
      süzgeç, doğrudan zincire yerleştirilip koşulsuz olarak
      çalıştırılabileceği gibi bir içerik sağlayıcı gibi kullanılarak zincire
      devingen olarak yerleştirilebilir. Örneğin:
    

    
      
      
    • Bir HTML işleme süzgeci sadece içerik text/html veya
      application/xhtml+xml olduğu takdirde çalışır.
      • 
      
    • Bir sıkıştırma süzgeci sadece girdi sıkıştırılabilir nitelikteyse ve
      sıkıştırılmamışsa çalışır.
      • 
      
    • Bir karakter kümesi dönüşüm süzgeci, bir metin belgesi istenen
      karakter kümesine sahip değilse zincire yerleştirilir.
      • 
    
    
  
    top
    

    

    Süzgeçleri bir HTTP Hizmeti gibi göstermek 
    
    
    
    Süzgeçler, istemciden kaynaklanan içeriği işlemekte kullanılabileceği
      gibi mod_reflector modülü kullanılarak sunucudan
      kaynaklanan içeriği işlemekte de kullanılabilir.
    

    
    mod_reflector istemcilerden gelen POST isteklerini
      kabul eder ve çıktı süzgeç yığıtı yoluyla istemciye aktararak, POST
      isteği içinde alınan içerik istek gövdesini yanıt içinde geri
      gönderir.
    

    
    Bu teknik, bir çıktı süzgeciyle istek gövdesinde gerekli dönüşümün
      sağlandığı durumda, bir uygulama sunucusu yığıtı içinde çalışan bir http
      hizmetinin yerine de kullanılabilir. Örneğin,
      mod_deflate modülü genel bir sıkıştırma hizmeti
      sağlamakta kullanılabilir veya bir resim dönüştürme süzgeci bir resim
      dönüşüm hizmeti haline getirilebilir.
    

  
    top
    

    

    Süzgeçlerin Kullanımı
    
    
    Süzgeçler iki şekilde kullanılır: Basit ve Devingen.
      Genelde ikisinden biri kullanılır; karışık kullanılırsa istenmeyen
      sonuçlara yol açabilir (ise de, basit girdi süzme ile çıktı süzme işlemi
      basit olsun olmasın karışık kullanılabilir).
    

    
    Basit yol, girdi süzgeçlerini yapılandırmanın tek yoludur ve bir
      durağan süzgeç zincirinin gerektiği yerlerde çıktı süzgeçleri için
      yeterlidir. İlgili yönergeler:
      SetInputFilter,
      SetOutputFilter,
      AddInputFilter,
      AddOutputFilter,
      RemoveInputFilter ve
      RemoveOutputFilter.
    

    
    Devingen yol, mod_filter belgesinde açıklandığı gibi,
      çıktı süzgeçlerinin hem durağan hem de esnek ve devingen olarak
      yapılandırılabilmesini mümkün kılar. İlgili yönergeler:
      FilterChain,
      FilterDeclare ve
      FilterProvider.
    

    
    AddOutputFilterByType yönergesi
      hala desteklenmekteyse de kullanımı artık
      önerilmemektedir. Onun yerine devingen yapılandırma kullanınız.

    Améliorations du Système de Base
    
        

        
    
            
    Threading Unix
    

            
    Sur les systèmes Unix qui supportent les threads
	    POSIX, Apache httpd
            peut à présent tourner en mode hybride multi-processus et 
            multi-threadé, ce qui augmente l'extensibilité et la performance 
            du serveur pour la plupart des configurations.
    

            
    Nouveau Système de Compilation
    

            
    Le processus de compilation a été refait de A à Z; 
            il utilise à présent autoconf et libtool, 
            ce qui rend la compilation d'Apache httpd plus familière aux utilisateurs 
            d'autre logiciels de mème type.
    

            
    Support Multiprotocole
    

            
    Le serveur HTTP Apache dispose désormais de
	    l'infrastructure nécessaire pour supporter
            d'autres protocoles. Le module mod_echo illustre ces 
            possibilités.
    

            
    Support amélioré des Plate-formes non-Unix
    
        
            
    Le serveur HTTP Apache 2.0 se montre plus rapide et plus stable sur les plate-formes 
            non Unix, telles BeOS, OS/2, NetWare et Windows. L'apparition des 
            Modules Multi-Processus (MPMs), ainsi que de 
            la bibliothèque "Apache Portable Runtime" (APR) permet à Apache de 
            tirer parti des API natives de ces plate-formes, sans s'appuyer sur leurs 
            couches POSIX souvent boguées et peu optimisées.
    

            
    Nouvelle API d'Apache httpd
    

            
    L'Interface de Programmation (API) des modules a beaucoup changé 
            avec le passage à la version 2.0.
            Les problèmes d'ordre et de priorité des modules, rencontrés 
            avec la version 1.3, devraient maintenant être résolus. Apache 2.0 
            gère ces problèmes de façon automatique. L'ordre des modules 
            est géré au moyen de "crochets" (hooks), ce qui rend la gestion 
            flexible. De nouveaux appels ont été également créés 
            afin de permettre l'implémentation d'autres fonctions dans les modules, 
            sans devoir corriger le noyau du serveur HTTP Apache.
    

            
    Support IPv6
    

            
    Sur les systèmes où la bibliothèque Apache Portable Runtime 
            supporte IPv6, Apache peut par défaut écouter sur des interfaces 
            de connexions IPv6. Les directives Listen, 
            NameVirtualHost et 
            VirtualHost supportent également 
            les adresses IPv6 (comme par exemple, dans "Listen[2001:db8::1]:8080").
    

            
    Filtering
    

            
    Il est maintenant possible d'écrire des modules
	    pour Apache  httpd pour filtrer
            les flux de données entrant ou sortant du serveur. A titre d'exemple, 
            il est possible de filtrer des directives Server Side Include de la sortie 
            standard d'un script CGI, au moyen du filtre INCLUDES fourni
            par le module mod_include. Le module
            mod_ext_filter permet quant à lui l'utilisation comme
            filtres de programmes externes à Apache, de la même manière 
            qu'on peut utiliser des programmes CGI comme Handlers.
    

            
    Réponses d'Erreurs Multilangues
    

            
    Les messages d'erreur envoyés au navigateur existent à présent en
            plusieurs langues avec des documents SSI. Ces messages peuvent être
            personnalisés par l'administrateur afin de s'intégrer avec le site web.
    

            
    Simplification de la Configuration
    

            
    Beaucoup de directives, auparavant peu claires, ont été simplifiées.
            Les directives Port et BindAddress, souvent
            sources d'incompréhension, ont disparus. Désormais seule la directive 
            Listen sert de liaison pour les 
            adresses IP; la directive ServerName ne 
            précise le nom du serveur et son port que pour les redirections et la
            gestion des hôtes virtuels.
    

            
    Support natif de l'Unicode sous Windows NT
    

            
    Apache httpd 2.0 sur Windows NT utilise à présent l'utf-8 pour tous les 
            noms de fichiers. Ces noms de fichiers sont directement traduits vers
            l'encodage Unicode du système de fichiers, ce qui permet le support
            multilangue pour toutes les installations sur la famille NT de Windows, y
            compris Windows 2000 et Windows XP.Ce support n'est pas fonctionnel
            pour Windows 95, 98 ni ME, qui utilisent les pages de code locales pour
            les accès au système de fichiers, comme auparavant.
    

            
    Mise à jour de la Bibliothèque d'Expressions Rationnelles
    

            
    Apache httpd 2.0 contient la bibliothèque 
            d'expressions rationnelles compatible Perl (Perl Compatible Regular 
            Expression Library - PCRE). Toutes les expressions rationnelles sont dont
            gérées avec la syntaxe de Perl 5, plus puissante.

    Amélioration des Modules
    
        

        
    
            
    mod_ssl
    

            
    Apparu dans Apache httpd 2.0, ce module est une interface aux protocoles de 
            chiffrement SSL/TLS fournis par OpenSSL.
    

            
    mod_dav
    

            
    Apparu dans Apache httpd 2.0, ce module implémente les spécifications HTTP de 
            gestion distribuée de versions et de rédaction (Distributed Authoring and 
            Versioning - DAV), destinées à la mise en ligne et à la maintenance des 
            contenus Web.
    

            
    mod_deflate
    

            
    Module apparu dans Apache httpd 2.0, mod_deflate permet aux navigateurs qui 
            le supportent de demander la compression des contenus envoyés par le serveur. 
            Cela a l'avantage de réduite l'occupation de la bande passante.
    

            
    mod_auth_ldap
    

            
    Apparu dans Apache httpd 2.0.41, ce module permet aux administrateurs
            d'utiliser un arbre LDAP pour gérer la base d'utilisateurs pour les 
            Authentifications Basiques HTTP. Un module voisin,
            mod_ldap, permet de globaliser les connexions à l'arbre LDAP
            et de garder en mémoire cache ces accès.
    
    
            
    mod_auth_digest
    

            
    Améliore les fonctions de cache sur une session entre les différents
            processus, en utilisant de la mémoire partagée.
    

            
    mod_charset_lite
    

            
    Apparu dans Apache httpd 2.0, ce module expérimental permet la conversion 
            et l'enregistrement entre jeux de caractères.
    

            
    mod_file_cache
    

            
    Apparu dans Apache httpd 2.0, ce module implémente les fonctionnalités du 
            module mod_mmap_static présent du serveur
	    HTTP Apache 1.3, et offre des 
            fonctions plus avancées pour la gestion du cache.
    

            
    mod_headers
    

            
    Ce module gagne beaucoup de flexibilité avec Apache
	    httpd 2.0 : on peut 
            désormais l'utiliser pour modifier les en-têtes des requêtes 
            utilisés par mod_proxy, et pour positionner les 
            en-têtes des réponses de manière conditionnelle.
    

            
    mod_proxy
    

            
    Le module proxy a été réécrit de A à Z. Il tire 
            maintenant avantage de la nouvelle infrastructure de filtrage, et implémente 
            un mandataire plus fiable, et conforme aux normes HTTP/1.1. De nouvelles 
            sections de configuration ajoutées à 
            <Proxy> 
            donnent un contrôle plus lisible et un traitement plus rapide des requêtes 
            mandatées ; les configurations surchargées <Directory 
            "proxy:..."> ne sont pas supportées. Le module a aussi été 
            fragmenté en plusieurs modules qui gèrent chacun leur protocole : 
            proxy_connect, proxy_ftp et 
            proxy_http.
    

            
    mod_negotiation
    

            
    Une nouvelle directive, ForceLanguagePriority a été ajoutée, 
            elle permet de garantir que le client reçoit un seul document dans tous les 
            cas, au lieu de réponses NOT ACCEPTABLE ou MULTIPLE CHOICES. Les 
            algorithmes gérant la négociation et les vues multiples (MultiViews) ont 
            été nettoyés et donnent des réponses plus logiques. Un nouveau format de 
            carte de types (map type) qui peut gérer le contenu de documents a 
            aussi été ajouté.
    
    
            
    mod_autoindex
    

            
    Les listes auto-générées par Autoindex sont à présent 
            configurables, et peuvent utiliser des tables HTML pour une mise en forme plus propre. 
            L'ordre d'affichage des fichiers est également finement paramètrable, 
            comme pour le tri par version, et le filtrage par caractères jokers du 
            listage du répertoire.
    

            
    mod_include
    

            
    De nouvelles directives permettent de modifier la valeur par défaut 
            des drapeaux start et end des éléments SSI. Ces directives 
            permettent à la configuration d'affichage de dates et heures d'être 
            effectuée dans le fichier de configuration principal, plutôt que dans le 
            document SSI. Les réponses données par des recherches par expressions 
            rationnelles (qui gèrent à présent les regex Perl) sont 
            recupérées au moyen des variables $0 à $9.
    

            
    mod_auth_dbm
    

            
    Plusieurs bases de données DBM sont supportées, et sélectionnables 
            via la directive AuthDBMType.

    Although the Apache HTTP Server provides generic error responses
    in the event of 4xx or 5xx HTTP status codes, these responses are
    rather stark, uninformative, and can be intimidating to site users.
    You may wish to provide custom error responses which are either
    friendlier, or in some language other than English, or perhaps which
    are styled more in line with your site layout.
    

    
    Customized error responses can be defined for any HTTP status
    code designated as an error condition - that is, any 4xx or 5xx
    status.
    

    
    Additionally, a set of values are provided, so
    that the error document can be customized further based on the
    values of these variables, using Server
    Side Includes. Or, you can have error conditions handled by a
    cgi program, or other dynamic handler (PHP, mod_perl, etc) which
    makes use of these variables.
    

  
    


    top
    

    

    Configuration
    

    
    Custom error documents are configured using the ErrorDocument directive,
    which may be used in global,
    virtualhost, or directory context. It may be used in .htaccess files
    if AllowOverride is set to
    FileInfo.
    

    
    ErrorDocument 500 "Sorry, our script crashed. Oh dear"
ErrorDocument 500 /cgi-bin/crash-recover
ErrorDocument 500 http://error.example.com/server_error.html
ErrorDocument 404 /errors/not_found.html
ErrorDocument 401 /subscription/how_to_subscribe.html
    


    
    The syntax of the ErrorDocument directive is:
    

    
    ErrorDocument <3-digit-code> <action>
    


    
    where the action will be treated as:
    

    
      
      
    1. A local URL to redirect to (if the action begins with a "/").
      2. 
      
    2. An external URL to redirect to (if the action is a valid URL).
      3. 
      
    3. Text to be displayed (if none of the above). The text must be
          wrapped in quotes (") if it consists of more than one word.
      4. 
    
    

    
    When redirecting to a local URL, additional environment variables
    are set so that the response can be further customized. They are not sent to
    external URLs.
    

  
    top
    

    

    Available Variables
    

      
    Redirecting to another URL can be useful, but only if some
      information can be passed which can then be used to explain or log
      the error condition more clearly.
    

      
    To achieve this, when the error redirect is sent, additional
      environment variables will be set, which will be generated from
      the headers provided to the original request by prepending
      'REDIRECT_' onto the original header name. This provides the error
      document the context of the original request.
    

      
    For example, you might receive, in addition to more usual
      environment variables, the following.
    

      
    
        REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/jpeg, image/png
    
        REDIRECT_HTTP_USER_AGENT=Mozilla/5.0 Fedora/3.5.8-1.fc12 Firefox/3.5.8
    
        REDIRECT_PATH=.:/bin:/usr/local/bin:/sbin
    
        REDIRECT_QUERY_STRING=
    
        REDIRECT_REMOTE_ADDR=121.345.78.123
    
        REDIRECT_REMOTE_HOST=client.example.com
    
        REDIRECT_SERVER_NAME=www.example.edu
    
        REDIRECT_SERVER_PORT=80
    
        REDIRECT_SERVER_SOFTWARE=Apache/2.2.15
    
        REDIRECT_URL=/cgi-bin/buggy.pl
      
    

      
    REDIRECT_ environment variables are created from
      the environment variables which existed prior to the
      redirect. They are renamed with a REDIRECT_
      prefix, i.e., HTTP_USER_AGENT becomes
      REDIRECT_HTTP_USER_AGENT.
    

      
    REDIRECT_URL, REDIRECT_STATUS, and
      REDIRECT_QUERY_STRING are guaranteed to be set, and
      the other headers will be set only if they existed prior to the
      error condition.
    

      
    None of these will be
      set if the ErrorDocument target is an
      external redirect (anything starting with a
      scheme name like http:, even if it refers to the same host
      as the server).
    
  
    top
    

    

    Customizing Error Responses
    

      
    If you point your ErrorDocument to some variety of
      dynamic handler such as a server-side include document, CGI
      script, or some variety of other handler, you may wish to use the
      available custom environment variables to customize this
      response.
    

      
    If the ErrorDocument specifies a local redirect to a CGI
      script, the script should include a "Status:"
      header field in its output in order to ensure the propagation
      all the way back to the client of the error condition that
      caused it to be invoked. For instance, a Perl ErrorDocument
      script might include the following:
    

       
    ...
print  "Content-type: text/html\n";
printf "Status: %s Condition Intercepted\n", $ENV{"REDIRECT_STATUS"};
...
    


      
    If the script is dedicated to handling a particular error
      condition, such as 404 Not Found, it can
      use the specific code and error text instead.
    

      
    Note that if the response contains Location:
      header (in order to issue a client-side redirect), the script
      must emit an appropriate Status: header
      (such as 302 Found). Otherwise the
      Location: header may have no effect.
    

  
    top
    

    

    Multi Language Custom Error Documents
    

    
    Provided with your installation of the Apache HTTP Server is a
    directory of custom error documents translated into 16 different
    languages. There's also a configuration file in the
    conf/extra configuration directory that can be included
    to enable this feature.
    

    
    In your server configuration file, you'll see a line such as:
    

    
    # Multi-language error messages
#Include conf/extra/httpd-multilang-errordoc.conf
    


    
    Uncommenting this Include line will enable this
    feature, and provide language-negotiated error messages, based on
    the language preference set in the client browser.
    

    
    Additionally, these documents contain various of the
    REDIRECT_ variables, so that additional information can
    be provided to the end-user about what happened, and what they can
    do now.
    

    
    These documents can be customized to whatever degree you wish to
    provide more useful information to users about your site, and what
    they can expect to find there.
    

    
    mod_include and mod_negotiation
    must be enabled to use this feature.

      mod_cache_disk, mod_file_cache
      modülleri ve htcacheclean
      için bir başvuru kılavuzu niteliğindedir. HTTP sunucusu ve vekil
      olarak çalışmada işlemleri hızlandırmak için bilinen sorunlar ve
      yanlış yapılandırmalardan kaçınarak Apache HTTPD sunucusunun önbellekleme
      özelliklerinin nasıl kullanılacağı açıklanmıştır.
    
  
    


    top
    

    

    Giriş
    
    

    
    Apache HTTP sunucusu, sunucunun başarımını çeşitli yollarla arttırmak
      üzere tasarlanmış bir dizi önbellekleme özelliğine sahiptir.
    

    
    
        
    Üç durumlu RFC2616 HTTP önbelleklemesi
    
        
    
            mod_cache ve destek modülü
            mod_cache_disk akılcı ve HTTP'ye uygun
            önbellekleme sağlar. İçeriğin kendisi önbellekte saklanır ve
            mod_cache, RFC2616'nın 13. bölümünde açıklandığı gibi, içeriğin
            önbelleklenebilirliğini denetleyen çeşitli HTTP başlıklarının ve
            seçeneklerinin tümünü onurlandırmayı hedefler.
            Devingen yerel içerik veya vekalet edilen içerik ile ilgilendiğiniz
            durumda veya muhtemel bir yavaş disk üzerinde yerel dosyalara
            erişimi hızlandırmak ihtiyacında olduğunuz durumda
            mod_cache hem basit hem de karmaşık önbellekleme
            yapılandırmalarını hedefler.
        
    
        
    İki durumlu anahtar/değer paylaşımlı nesne önbellekleme
    
        
    
            Paylaşımlı nesne önbellek API'si
            (socache) ve destek modülleri sunucu taraflı bir anahtar/değer
            paylaşımlı nesne önbelleklemesi sağlar. Bu modüller SSL oturumları
            ve kimlik doğrulama bilgileri gibi düşük seviyeli verileri
            önbelleklemek için tasarlanmıştır. Destek modülleri verinin sunucu
            tarafı bir paylaşımlı bellekte veya veri merkezi tarafı memcache
            veya distcache gibi bir önbellekte saklanmasını mümkün kılar.
        
    
        
    Uzmanlaşmış dosya önbellekleme
    
        
    
            mod_file_cache dosyaların sunucunun başlatılması
            sırasında  belleğe yüklenmesi ile ilgilenir. Böylece dosyalara
            erişim zamanını kısaltabilir, sıkça erişilen dosyaların dosya
            tanıtıcılarını kaydedebilir, her istekte diske gitme ihtiyacını
            ortadan kaldırır.
        
    
    
    

    
    Bu belgeden azami yararı sağlayabilmek için temel bir HTTP bilginizin
      olması ve URL’lerin Dosya Sistemine
      Eşlenmesi ile İçerik Uzlaşımı
      belgelerini okumuş olmanız gerekir.

    Üç durumlu RFC2616 HTTP önbelleklemesi
    

    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    HTTP protokolü
      RFC2616'nın 13. bölümünde açıklanan satıriçi önbellekleme
      mekanizması için yerleşik bir destek içerir ve bunun getirilerinden
      yararlanmak için mod_cache modülü kullanılabilir.
    

    
    İçeriğin taze olmadığı durumda içeriğin kaybolmasına sebep olan basit
      iki durumlu anahtar/değer önbelleklemesinin tersine, HTTP önbelleği
      eskimiş içeriği tutan ve bu eski içeriğin değişip değişmediğini özgün
      sunucuya soran ve duruma göre onu tekrar taze duruma getiren bir
      mekanizma içerir.
    

    
    HTTP önbelleğinde bulunan bir girdi şu üç durumdan birinde olabilir:
    

    
    
    
    Taze
    
    
    
        İçerik yeteri kadar yeni (tazelik ömründen daha genç)
        ise taze sayılır. Bir HTTP önbelleği böyle bir içeriği
        özgün sunucuya birşey sormadan sunabilir.
    
    
    
    Bayat
    
    
    
        
    İçerik çok eski (tazelik ömründen daha yaşlı)
        ise bayat sayılır. Bir HTTP önbelleği böyle bir
        içeriği istemciye sunmadan önce özgün sunucuya bağlanıp bayat içeriğin
        hala yeterince taze olup olmadığına bakmalıdır. Özgün sunucu, içerik
        geçersizse yenisini gönderecektir, aksi takdirde, (ideal olanı budur)
        içeriğin hala geçerli olduğunu belirten bir kod ile yanıt verecektir.
        İçerik tekrar taze hale gelince süreç kaldığı yerden devam eder.
    

        
    HTTP protokolü belli koşullar altında önbelleğin bayat içeriği
        sunmasına izin vermez. Örneğin, bir içeriği özgün sunucuda tazeleme
        çabasının bir 5xx hatasıyla başarısız olması veya başka bir tazeleme
        isteğinin henüz sonuçlanmamış olması bu çeşit koşullardandır. Bu
        durumlarda yanıta bir Warning başlığı eklenir.
    
    
    
    
    Yok
    
    
    
        Önbellekte yer kalmazsa yer açmak için içeriğin silinmesi seçenek
        dahilindedir. İçerik taze olsun olmasın her zaman silinebilir. Önlem
        olarak htcacheclean elle veya bir artalan süreci
        olarak çalıştırılabilir. Böylece önbelleğin boyutunun belirtilen
        boyutta veya belirtilen dosya düğümü sayısında kalması sağlanabilir.
        Araç içeriği silerken bayat içeriğe öncelik verir.
    
    
    
    

    
    HTTP önbelleklemesinin çalışması ile ilgili bütün ayrıntılar
    RFC2616'nın 13. bölümünde bulunabilir.
    

    
    Sunucu ile etkileşim
    
      

      
    mod_cache modülü
      CacheQuickHandler yönergesinin
      değerine bağlı olarak iki olası yerde sunucuya bağlanır:
      
    

      
    
      
    Çabuk eylem aşaması
    
      
    
          
    Bu aşama çok erken gerçekleşen bir aşama olup isteğin işlenmesi
          sırasında isteğin çözümlenmesinin hemen sonrasıdır. İçerik
          önbellekte mevcutsa hemen sunulur ve geri kalan istek işleme işlemi
          iptal edilir.
    

          
    Bu senaryoda önbellek sunucunun önüne vidalanmış gibi
          davranır.
    

          
    Sunucuda gerçekleşecek bir dizi işlemin büyük çoğunluğunun
          yapılmadan geçilmesi nedeniyle bu en yüksek başarımlı kiptir.
          Bu kip ayrıca, sunucu işlemlerinin kimlik doğrulama ve yetkilendirme
          aşamalarının da yapılmadan geçilmesini sağlar. Bu bakımdan bu kip
          seçilirken bu durum dikkate alınmalıdır.
    

          
    "Authorization" başlığı içeren istekler (örneğin, HTTP Temel
          Kimlik Kanıtlaması gibi) mod_cache bu kipte
          çalışırken önbelleğe alınmadıkları gibi önbellekten bir işleme de
          sokulmazlar.
    
      
    
      
    Normal eylem aşaması
    
      
    
          
    Bu aşama geç bir aşama olup, isteğin tamamen işlenmesinin
          sonrasıdır.
    

          
    Bu senaryoda önbellek sunucunun arkasına vidalanmış gibi
          davranır.
    

          
    Bu kip en esneğidir. Önbelleğin, süzme zincirinin hassas olarak
          denetlenen bir noktasında oluşması sağlanabilir ve önbelleklenen
          içerik istemciye gönderilmeden önce süzülüp
          kişiselleştirilebilir.
    
          
    
        
    

        
    URL önbellekte yoksa mod_cache modülü yanıtı
          önbelleğe kaydetme aşamasında süzgeç yığıtına bir
          süzgeç ekler ve geri çekilerek normal istek
          işlemlerinin devam etmesine izin verir. İçeriğin önbelleklenebilir
          olduğu saptanırsa içerik gelecekte sunulmak üzere önbelleğe
          kaydedilir, aksi takdirde içerik yok sayılır.
    

        
    Önbellekteki içerik bayatsa, mod_cache modülü
          isteği bir koşullu istek haline getirir. Özgün
          sunucu normal bir yanıt verirse bu yanıt mevcut içeriğin yerine
          önbelleklenir. Özgün sunucu bir 304 Not Modified yanıtı
          verirse içerik tekrar taze olarak imlenir ve önbellekteki içerik
          süzgeç tarafından kaydedilmeden sunulur.
    
    

    
    Önbelleğin Hızlandırılması
    
      

      
    Bir sanal konak birçok farklı sunucu takma adından biri olarak
        bilindiği takdirde UseCanonicalName yönergesine On
        değeri atanmışsa önbellekten sunulan sayfa sayısında büyük bir artış
        olduğu görülür. Bunun sebebi içeriği sunan sanal konağın isminin
        önbellek anahtarının içinde kullanılmasıdır. Yönergeye
        On değerini atamak suretiyle çok isimli ve rumuzlu sanal
        konaklar için farklı önbellek girdileri oluşturulmaz, bunun yerine her
        meşru sanal konak için ayrı bir önbellek tutulur.
    
    

    
    Tazelik Ömrü
    
      

      
    Önbelleklenmek üzere tasarlanmış iyi biçimli bir içerik tazelik ömrünü
        Cache-Control başlığının  max-age veya
        s-maxage alanlarıyla ya da bir Expires
        başlığını içererek bildirmelidir.
    

      
    Aynı zamanda, özgün sunucunun tanımladığı tazelik ömrü, bir istemci
        tarafından istekte bir Cache-Control başlığı kullanılarak
        geçersiz kılınmak istenebilir. Bu durumda hangi tazelik ömrü daha
        kısaysa o geçerli olur.
    

      
    Tazelik ömrü istekte veya yanıtta mevcut değilse öntanımlı bir tazelik
        ömrü kullanılır. Öntanımlı tazelik ömrü önbellekli içerik için bir saat
        olmakla birlikte CacheDefaultExpire yönergesi
        kullanılarak kolayca değiştirilebilir.
    

      
    Bir yanıt Expires başlığını değil de
        Last-Modified başlığını içeriyorsa
        mod_cache tazelik ömrünü CacheLastModifiedFactor yönergesine
        bakarak saptar.
    

      
    Yerel içerik için, ya da kendi Expires başlığını
        tanımlamayan uzak içerik için tazelik ömrünü max-age ve
        Expires ekleyerek hassas olarak ayarlamak
        için mod_expires kullanılabilir.
    

      
    Tazelik ömrünün üst sınırı CacheMaxExpire yönergesi ile
        belirlenebilir.
    
    

    
    Şartlı İstekler için Özlü Kılavuz
    
      

      
    Önbellekteki içeriğin zaman aşımına uğrayıp bayat hale gelmesi,
        httpd’nin özgün isteği aktarmak yerine isteği değişikliğe uğratarak
        şartlı bir istek yapması sonucunu doğurur.
    

      
    Özgün önbellekli yanıtta bir ETag başlığı mevcutsa,
        mod_cache modülü özgün sunucuya yapılan isteğe
        bir If-None-Match başlığı ekler.
        Özgün önbellekli yanıtta bir Last-Modified başlığı
        mevcutsa, mod_cache modülü özgün sunucuya yapılan
        isteğe bir If-Modified-Since başlığı ekler. Bunlardan
        birinin varlığı isteği koşullu yapar.
    

      
    Bir koşullu istek özgün sunucu tarafından alındığında, özgün sunucu
        ETag veya Last-Modified başlığının isteğe
        uygun olarak değişip değişmediğine bakmalıdır. Değişmemişse, özgün
        sunucu kısa ve öz bir "304 Not Modified" yanıtı ile yanıt vermelidir.
        Bunun önbellekteki anlamı şudur: Eskimiş içerik hala tazedir ve içerik
        yeni tazelik ömrüne ulaşıncaya kadar sonraki isteklerde
        kullanılmalıdır.
    

      
    İçerik değişmişse, bir şartlı istek yapılmamış gibi içeriğin kendisi
        sunulur.
    

      
    Şartlı istekler çifte yarar sağlar. Birinci olarak, böyle bir istek
        özgün sunucuya yapılıyorsa ve iki içerik de aynıysa bunu saptamak kolay
        olur ve özkaynağın tamamını aktarma külfetinden kurtulunur.
    

      
    İkinci olarak, iyi tasarlanmış bir özgün sunucu, koşullu istekler tam
        bir yanıt üretmekten önemli ölçüde ucuz olacak şekilde tasarlanmış
        olacaktır. Durağan dosyalar için bu genellikle
        stat() veya  benzeri bir sistem çağrısıyla dosya
        boyutları ve değişiklik zamanına bakmak şeklinde gerçekleşir.
        Böylelikle, yerel içeriği bir değişiklik olmadığı takdirde önbellekten
        sunmak daha hızlı olacaktır.
    

      
    Özgün sunucular koşullu istekleri desteklemek için her türlü çabayı
        göstermelidir. Ancak, koşullu istekler desteklenmiyorsa, özgün sunucu
        istek koşullu değilmiş gibi yanıt vermeli, önbellek ise, içerik
        değişmiş ve yani içerik önbelleğe kaydedilmiş gibi yanıt vermelidir. Bu
        durumda, önbellek basit bir iki durumlu (içerik ya tazedir ya da
        silinmiş) önbellek gibi davranacaktır.
    
    

    
    Neler Önbelleklenebilir?
    
      

      
    HTTP önbelleğin tarafından önbelleklenebilecek içerik

       RFC2616 Section 13.4 Response Cacheability belgesinde tanımlanmış
       olup, bunlar şöyle özetlenebilir:
    

      
      
        
    1. Önbellekleme bu URL ile etkin kılınabilmelidir. CacheEnable ve CacheDisable yönergelerine bakınız.
      2. 

        
    2. Yanıtın HTTP durum kodu 200, 203, 300, 301 veya 410 olmalıdır.
      3. 
        
        
    3. Yanıtın HTTP durum kodu 200, 203, 300, 301 veya 410 değilse 
          yanıtın ayrıca, "Expires" veya "Cache-Control" başlığı da içermesi 
          gerekir.
      4. 

        
    4. İstek bir HTTP GET isteği olmalıdır.
      5. 

        
    5. Eğer yanıt bir "Authorization:" başlığı içeriyorsa ayrıca
          "Cache-Control:" başlığında da "s-maxage", "must-revalidate" veya
          "public" değerlerinden birini içermelidir, aksi takdirde
          önbelleklenmez.
      6. 

        
    6. Eğer URL (GET yöntemi kullanan bir HTML formunun yaptığı gibi) bir
          sorgu dizgesi içeriyorsa  yanıt, RFC2616’nın 13.9. bölümünde
          açıklandığı gibi bir "Expires:" başlığı içermedikçe veya
          "Cache-Control:" başlığının max-age veya max-age yönergesini
          içermedikçe yanıt içeriği önbelleğe alınmayacaktır.
      7. 

        
    7. CacheIgnoreNoLastMod
          yönergesinin kullanımını gerektiren bir durum olmadıkça 200 durum
          koduna sahip bir yanıtın "Etag", "Last-Modified" ve "Expires"
          başlıklarından birini veya "Cache-Control:" başlığının "max-age" veya
          "s-maxage" yönergelerinden birini (en azından) içermesi gerekir.
      8. 

        
    8. CacheStorePrivate
          yönergesinin kullanımını gerektiren bir durum olmadıkça yanıt
          "private" değerli bir "Cache-Control:" başlığı içerdiği takdirde
          yanıtın içeriği önbelleğe alınmayacaktır.
      9. 

        
    9. Benzer şekilde, CacheStoreNoStore yönergesi kullanılmamışsa yanıt
          "no-store" değerli bir "Cache-Control:" başlığı içeriyorsa yanıt
          içeriği önbelleğe alınmayacaktır.
      10. 

        
    10. Herşeyle eşleşen "*" değerli bir "Vary:" başlığı içeren bir
          yanıtın içeriği önbelleğe alınmaz.
      11. 
      
    
    

    
    Neler Önbelleklenmemeli?
    
      

      
    İçerik zamana bağımlıysa ya da istek kısmen bile olsa HTTP uzlaşımıyla
        bağdaşmıyorsa önbelleğe alınmamalıdır. Bu içerik önbelleklenemeyeceğini
        Cache-Control başlığını kullanarak sunucuya
        bildirmelidir.
    

      
    İçerik sıkça değişiyorsa, tazelik ömrü dakikalar veya saniyelerle
        ifade ediliyorsa, içerik yine de önbelleklenebilir. Ancak, tam
        yanıtların düzenli olarak üretilmemesinin temini için  özgün sunucunun
        koşullu istekleri doğru olarak desteklemesi
        sağlanmalıdır.
    

      
    İstemcinin sağladığı istek başlıklarına dayanarak değişen içerik,
        Vary yanıt başlığının akıllıca kullanımıyla
        önbelleklenebilir.
    
    

    
    Değişken/Uzlaşımlı İçerik
    
      

      
    Özgün sunucu, istekteki başlık değerlerine dayanarak farklı
        içeriklerle yanıt vermeye ayarlandığı takdirde, örneğin aynı URL'de
        farklı dillerde içerik sunmak gibi, HTTP'nin önbellekleme mekanizması
        aynı URL'de aynı sayfanın değişik sürümlerini önbelleklemeyi mümkün
        kılar.
    

      
    Bu özgün sunucu tarafından bir Vary başlığı eklenerek
        yapılır. Bir sayfanın farklı sürümleri arasındaki farkları saptarken
        önbellek tarafından hangi başlıkların hesaba katılacağını
        Vary başlığı belirler.
    

      
    Örneğin, bir yanıt şöyle bir başlık ile alınmışsa,
    

      
    
        Vary: negotiate,accept-language,accept-charset
      
    

      
    mod_cache sadece accept-language ve accept-charset
        başlıkları özgün istekle eşleşen önbellekli içeriği sunacaktır.
    

      
    İçeriğin farklı sürümleri yan yana önbelleklenebilir.
        mod_cache modülü Vary başlığını
        kullanarak başlıkta listelenmiş istek başlıklarının uygun değerlerini
        saptar ve istemciye hangi sürümle yanıt verileceğine karar verir.

    Önbellek Ayarlama Örnekleri
    

    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    Disk Üzerinde Önbellekleme
    
      

      
    mod_cache modülü önbelleği yönetmek için çeşitli
      depolama ortamlarına özgü gerçeklenimleri kullanır. Diske önbellekleme
      desteğini mod_cache_disk sağlar.
    

      
    Tipik olarak modül şöyle yapılandırılır:
    

      
    CacheRoot   "/var/cache/apache/"
CacheEnable disk /
CacheDirLevels 2
CacheDirLength 1
    


      
    En önemlisi önbelleklenen dosyaların yerel olarak saklanması olup
        işletim sisteminin sağladığı bellekiçi önbelleklemeden de ayrıca
        faydalanılmış olur. Bu bakımdan, dosyalar disk üzerinde saklansa bile
        sıkça erişilen dosyalar işletim sistemi sayesinde aslında bellekten
        sunulmuş olacaklardır.
    
    

    
    Önbellekte Saklamanın Anlamı
    
      

      
    mod_cache_disk öğeleri önbellekte saklamak için
        istek yapılan URL’nin 22 karakterlik özetini oluşturur. Bu özet, çok
        sayıda URL’nin aynı özeti oluşturmaması için konak ismi, protokol,
        port ve varsa CGI argümanlarından başka Vary başlığında
        tanımlı elemanlardan oluşur.
    

      
    Özeti oluşturan karakterler 64 karakterlik bir karakter kümesinden
        seçildiğinden oluşturulması olası farklı özet sayısı 64^22’dir.
        Örneğin, bir URL’nin xyTGxSMO2b68mBCykqkp1w gibi bir
        özeti olabilir. Bu özet, bu URL ile erişilen dosyalar önbellek içinde
        saklanırken dosya ismi öneki olarak kullanılır. Ancak bununla
        yetinilmez ve içerik CacheDirLevels ve CacheDirLength yönergelerinin
        değerlerine göre önce dizinlere ayrılır.
    

      
    CacheDirLevels
        yönergesi kaç alt seviye dizin olacağını ve CacheDirLength her dizinde kaç
        karakter olacağını belirler. Örneğin, yukarıdaki
        özete sahip bir dosyanın isminin başına yukarıdaki yapılandırma
        örneğine uygun olarak
        /var/cache/apache/x/y/TGxSMO2b68mBCykqkp1w gibi bir önek
        getirilebilirdi.
    

      
    Bu tekniğin asıl amacı belli bir dizin içinde bulunabilecek
        dosyaların ve alt dizinlerin sayısını düşük tutmaktır. Bu sayının
        büyük olması çoğu işletim sisteminde başarımın düşmesine sebep olur.
        CacheDirLength
        yönergesi "1" değeriyle kullanıldığında her dizin altında en fazla 64
        alt dizin veya dosya açılabilir. "2" değeriyle kullanıldığında ise bu
        sayı 64^2’ye yükselir ve böyle artarak gider. İyi bir sebebiniz
        olmadıkça CacheDirLength için değer olarak
        "1" belirtmenizi öneririz.
    

      
    CacheDirLevels
        yönergesine atanacak değer önbellekte saklamayı düşündüğünüz olası
        dosya sayısı ile ilgilidir. Yukarıdaki örnekte olduğu gibi "2"
        değerini belirtirseniz, toplamda en fazla 4096 dizin oluşturulabilir.
        1 milyon dosyanın önbelleklendiği bir durumda bu, her dizinde yaklaşık
        olarak 245 önbelleklenmiş URL demektir.
    

      
    Her URL için önbellekte en az iki dosya saklanır. Biri genellikle URL
        hakkındaki temel verilerden oluşan ".header" dosyasıdır, diğeri ise
        sunulacak içeriğin bire bir kopyası olan ".data" dosyasıdır.
    

      
    "Vary" başlığı üzerinden içeriğin uzlaşıldığı durumda URL için bir
        ".vary" dizini oluşturulur. Bu dizin her biri farklı bir uzlaşıma ait
        çok sayıda ".data" dosyası içerebilir.
    
    

    
    Disk Önbelleğinin Bakımı
    
      

      
    mod_cache_disk zaman aşımına uğrayan önbellekli
        içeriği silse de önbelleğin toplam boyu ve ne kadar boş bellek kaldığı
        hakkında bilgi vermez.
    

      
    Bunun yerine httpd önbellek içeriğini düzenli aralıklarla
        temizleyebilmeniz için htcacheclean adında bir araç
        içerir.  Önbellek için azami ne kadar yer kullanılacağının ve bunun
        üzerinde htcacheclean’i hangi sıklıkta
        çalıştırılacağının tespiti biraz karmaşık bir işlem olup uygun değerler
        genellikle deneme yanılma yoluyla bulunur.
    

      
    htcacheclean iki işlem kipine sahiptir. Kalıcı bir
        artalan süreci olarak çalışabileceği gibi cron üzerinden belli
        aralıklarla da çalıştırılabilir. Çok büyük (onlarca GB) önbelleklerde
        htcacheclean’in işini bitirmesi 1 saatten fazla
        sürebileceğinden, cron ile çalıştırma durumunda aynı anda birden fazla
        kopyanın çalışıyor durumda olmaması için
        htcacheclean’in çalıştırılma aralığını iyi
        belirlemek gerekir.
    

      
    Ayrıca, htcacheclean için uygun bir "nice" seviyesi
        seçilmesi önerilr. Böylece, sunucu çalışırken aracın ölçüsüz disk g/ç
        yapmasına sebebiyet verilmemiş olur.
    

      
    
      
    
      Şekil 1:
 Önbelleğin büyümesi ve düzenli aralıklarla temizlenmesi.
    

      
    mod_cache_disk ne kadar bellek kullanıldığı hakkında
        bilgi vermediğinden, htcacheclean'in bir temizliğin
        ardından yeterli bir büyüme alanı kalacak şekilde yapılandırılması
        temin edilmelidir.
    
    
    
    
    memcached ile önbellekleme
    
      

      
    mod_cache_socache modülünü kullanarak, 
        mod_cache çeşitli gerçeklenimlerden (diğer adıyla: 
        "sağlayıcılar"dan) gelen veriyi önbellekleyebilir.   
        mod_socache_memcache modülü kullanılarak, örneğin, 
        artalan saklama mekanizması olarak 
        memcached kullanıldığı 
        söylenebilir.
    

      
    Genelde modül şöyle yapılandırılır:
    

      
    CacheEnable socache /
CacheSocache memcache:memcd.example.com:11211
    


      
    İlave memcached sunucular 
        CacheSocache memcache: satırının ardına virgüllerle 
        ayrılarak eklenebilir:
    

      
    CacheEnable socache /
CacheSocache memcache:mem1.example.com:11211,mem2.example.com:11212
    


      
    Bu biçim diğer mod_cache_socache sağlayıcıları için de kullanılabilir:
    

      
    CacheEnable socache /
CacheSocache shmcb:/path/to/datafile(512000)
    


      
    CacheEnable socache /

    Uzmanlaşmış Dosya Önbellekleme
    
    

     
    İlgili Modüllerİlgili Yönergeler
    

    
    Dosya sisteminin yavaş olabildiği veya dosya tanıtıcılarının
      kullanımının pahalıya mal olduğu sistemlerde, sunucunun başlatılması
      sırasında dosyaların belleğe yüklenmesi seçeneği vardır.
    

    
    Dosyaların açılmasının yavaş olduğu sistemlerde, dosyaların sunucunun
      başlatılması sırasında açılması ve dosya tanıtıcısını önbelleklenmesi
      seçeneği vardır. Bu seçeneklerin duruk dosyalara erişimin yavaş olduğu
      sistemlere de bir yardımı olabilir.
    

    
    Dosya Tanıtıcı Önbelleklemesi
    
      

      
    Bir dosyanın açılması işlemi, özellikle de ağ dosya sistemlerinde
        bulunan dosyalar için önemli bir gecikme kaynağı olabilir. Önbellekte,
        çok sunulan dosyaların kendilerinin değil, açık dosya tanıtıcılarının
        saklanması httpd’yi bu tür gecikmelerden koruyabilir. httpd’de tek
        türde dosya tanıtıcı önbelleklemesi yapılabilmektedir.
    

      
    CacheFile yönergesi ile
    
        

        
    httpd’de mevcut önbelleklemenin en temel şekli
          mod_file_cache tarafından sağlanan dosya tanıtıcı
          önbelleklemesidir. Bu önbellek türü dosyaların kendilerini değil açık
          dosya tanıtıcılarının bir listesini saklar. Dosyaların bu anlamda
          önbelleklenmesi, CacheFile yönergesi yapılandırma dosyasında belirtilerek
          sağlanabilir.
    

        
    CacheFile yönergesi
          belirtilen dosyanın httpd başlatıldığında açılmasını ve dosya için
          yapılan sonraki her istekte bu dosya tanıtıcısının kullanılmasını
          sağlar.
    

        
    CacheFile /usr/local/apache2/htdocs/index.html
    


        
    Büyük miktarda dosyayı bu anlamda önbelleklemeyi tasarlıyorsanız
          işletim sisteminizin açık dosya tanıtıcılarının sayısı ile ilgili
          sınırlamasını uygun bir değere ayarlamanız gerekebilir.
    

        
    CacheFile yönergesini
          kullandığınız takdirde dosya içeriğindeki değişiklikleri anında
          isteğe yansıtamazsınız. httpd dosyayı ilk başlatıldığındaki haliyle
          sunar.
    

        
    Eğer httpd çalışırken dosya silinmişse httpd ilk başlatıldığındaki
          haline ilişkin dosya tanıtıcıyı sağlamaya ve dolayısıyla dosya
          içeriğini sunmaya devam edecektir. Yani, dosya silinmiş ve artık
          dosya sisteminde görünmüyor olsa bile httpd durdurulup dosya
          tanıtıcıları kapanmadıkça dosyaların silinmesiyle açılan yer serbest
          kalmayacaktır.
    
      

    

    
    Sistem Belleğinde Önbellekleme
    
      

      
    İçeriğin sistem belleğinden sunulması içerik sunmanın evrensel olarak
      en hızlı yoludur. Dosyaların bir disk denetleyiciden okunması ya da daha
      kötüsü uzak bir ağdan okunması bellekten okumayla karşılaştırılamayacak
      ölçüde yavaş işlemlerdir. Disk denetleyiciler genellikle fiziksel
      süreçleri denetlerler. Ağ erişimi ise band genişliği sınırlamalarından
      etkilenir. Halbuki bellek erişimi sadece nano saniyeler mertebesinde
      gerçekleşir.
    

      
    Sistem belleği en pahalı saklama ortamı olması sebebiyle en verimli
      şekilde kullanımı önemlidir. Dosyaları sistem belleğinde saklamakla
      sistemin kullanabileceği bellek miktarını azaltmış olursunuz. İşletim
      sistemi önbelleklemesinde göreceğiniz gibi bu öyle basit bir konu
      değildir. httpd’nin kendi kullandığı belleğin bir kısmını önbellek
      olarak ayırırken çok fazla bellek kullanmamak önemlidir. Aksi takdirde
      işletim sistemi belleğin yetmediği noktada belleği diske
      takaslayacağından istenen başarım artışı sağlanamayacaktır.
    

      
    İşletim Sistemi Önbelleklemesi
    
        

        
    Günümüz iştetim sistemlerinin hemen hemen tamamında bellek içi
        dosya/veri saklama işlemlerini çekirdek yönetir. Bu güçlü bir
        özelliktir ve işletim sistemlerinin büyük çoğunluğu bunu böyle yapar.
        Örneğin, Linux’ta bir dosyanın ilk defa okunduğunda ve ikinci kez
        okunduğunda işlemcinin ne kadar meşgul edildiğine bakalım:
    

        
    
          colm@coroebus:~$ time cat testfile > /dev/null
    
          real    0m0.065s
    
          user    0m0.000s
    
          sys     0m0.001s
    
          colm@coroebus:~$ time cat testfile > /dev/null
    
          real    0m0.003s
    
          user    0m0.003s
    
          sys     0m0.000s
        
    

        
    Küçük bir dosya için bile okuma süresi bakımından büyük fark ortaya
          çıkmaktadır. Bunun sebebi çekirdeğin dosya içeriğini bellek daha
          güncel amaçlar için lazım olana dek bellek içinde saklamasıdır.
    

        
    Sisteminizde yeterince yedek bellek olduğundan eminseniz, bu
          önbellekte daha fazla dosya saklanacağından emin olabilirsiniz.
          Bundan, önbelleğin sistem belleğinde verimli biçimde tutulması için
          httpd’de ek bir yapılandırmaya gidilmesinin gerekmediği sonucu
          çıkarılabilir.
    

        
    Bundan başka, işletim sistemi dosyaların değiştiği ve silindiği
          zamanları bildiğinden bu tür dosyaların içerikleri gerektiğinde
          önbellekten kendiliğinden silinmiş olur. Bellek içinde dosya
          saklarken dosyaların değiştirilme zamanlarını bilme olanağı
          olmadığından bu durum httpd’ye büyük yarar sağlar.
    
      

      
    İşletim sisteminin dosyaların önbelleklenmesi için sağladığı bunca
        yarara ve başarım artışına karşın bellek içinde dosya önbelleklemenin
        httpd tarafından yerine getirilmesinin daha iyi olacağı bazı durumlar
        vardır.
    

      
    MMapFile yönergesi ile
    
        

        
    mod_file_cache modülü, bir durağan dosyanın
          içeriğini sunucunun başlatılması sırasında (mmap sistem çağrısıyla)
          belleğe eşlenmesini mümkün kılmak için MMapFile yönergesini sağlar.
          httpd bu dosyaya gelecek sonraki istekler için dosyanın bellekiçi
          içeriğini kullanacaktır.
    

        
    MMapFile /usr/local/apache2/htdocs/index.html
    


        
    CacheFile
          yönergesinde olduğu gibi bu dosyalarda httpd başlatıldıktan sonra
          yapılacak bir değişiklikten httpd’nin haberi olmayacaktır.
    

        
    MMapFile yönergesi
          ayırdığı belleğin toplam miktarı ile ilgilenmez, dolayısıyla
          yönergenin aşırı kullanımından kaçınmalısınız. httpd’nin çocuk
          süreçlerinin her biri bu belleğin kendilerine ait birer kopyasını
          yapacağından belleğe eşlenen dosyaların çok yer kaplamaması büyük
          önem taşımaktadır; aksi takdirde işletim sistemi belleği diske
          takaslayacağından beklenen fayda sağlanamayacaktır.

    Güvenlik Kaygıları
    
    

    
    Erişim Denetimi ve Yetkilendirme
    
      

      
    CacheQuickHandler
        yönergesine On değerinin atandığı öntanımlı durumda
        mod_cache kullanımı, daha çok sunucunun önüne
        vidalanmış önbelleklemeli bir karşı vekile sahip olmak gibidir. Özgün
        sunucunun bir harici önbellekmiş gibi sorgulanmasını gerektirmeyen tüm
        istekler önbellekleme modülü tarafından karşılanacaktır. Bu durum
        httpd'nin güvenlik modelini büyük ölçüde değiştirir.
    

      
    Olası .htaccess dosyalarının dosya sisteminin tamamında
        taranması çok pahalı bir işlem olduğundan mod_cache,
        (işlemi hızlandırmak için) önbelleğe almanın temel amacını kısmen
        gözardı ederek, önbellekteki içeriğin sunumu için gerekli
        yetkilendirmenin olup olmadığı konusunda bir karar üretmez. Başka bir
        deyişle, eğer mod_cache bir kısım içeriği önbelleğe
        almışsa içerik zaman aşımına uğramadığı sürece bu içerik önbellekten
        sunulacaktır.
    

      
    Örneğin, yapılandırmanız bir özkaynağa IP adresine göre erişime izin
        veriyorsa bu içeriğin önbelleğe alınmayacağından emin olmalısınız.
        Bunu CacheDisable
        yönergesini veya mod_expires modülünü kullanarak
        yapabilirsiniz. Bunu yapmaz, olayı kendi haline bırakırsanız
        mod_cache bir karşı vekil gibi çalışarak sunulan her
        içeriği önbelleğe alacak ve hangi IP adresinden gelirse gelsin her
        istemciye bunu sunacaktır.
    

      
    CacheQuickHandler
        yönergesine Off atandığı takdirde, istek işleme
        aşamalarının tamamı yerine getirilir ve güvenlik modeli değişmeden
        kalır.
    
    

    
    Yerel İstismarcılar
    
      

      
    Son kullanıcılarıın isteklerine önbellekten hizmet sunulduğundan
        önbelleğin kendisi içerikle etkileşime geçmek isteyenlerin veya
        içeriği tahrif etmek isteyenlerin hedefi haline gelebilir. httpd’yi
        çalıştıran kullanıcı tarafından her zaman önbelleğe yazılabileceğini
        akıldan çıkarmamak önemlidir. Bu durumda alışılmışın tersine tüm
        içeriğin Apache kullanıcısı tarafından yazılamamasının sağlanması
        önerilir.
    

      
    Eğer Apache kullanıcısı, örneğin bir CGI sürecindeki açık nedeniyle
        tehlikeye atılırsa, önbellek hedef alınabilir.
        mod_cache_disk kullanılırken önbellekteki bir öğeyi
        değiştirmek veya önbelleğe yeni bir öğe eklemek görece daha
        kolaydır.
    

      
    Bu risk, Apache kullanıcısını kullanan diğer saldırı türleriyle
        karşılaştırıldığında daha yüksektir. mod_cache_disk
        kullanıyorsanız şunları aklınızdan çıkarmayın: (1) httpd güvenlik
        güncellemelerini takip edin ve sunucunuzu buna göre güncelleyin. (2)
        Mümkünse suEXEC kullanarak CGI süreçlerini
        Apache kullanıcısı olmayan bir kullanıcının aidiyetinde çalıştırın.
    
    

    
    Önbellek Zehirlenmeleri
    
      

      
    httpd bir önbellekli vekil sunucu olarak çalıştığında önbellek
        zehirlenmesi adı verilen sorunla karşılaşılma olasılığı vardır.
        Önbellek zehirlenmesi, vekil sunucunun özgün sunucudan yanlış (ve
        genellikle istenmeyen) içerik almasına sebep olan bir saldırı türünü
        betimlemek için yaygın olarak kullanılan bir terimdir.
    

      
    Örneğin httpd’nin çalıştığı sistemin kullandığı DNS sunucuları DNS
        önbellek zehirlenmesinden etkilenebilecek durumdaysa, bir saldırgan
        httpd’nin istekleri almak için başvuracağı kaynak sunucunun yerini
        değiştirebilir. Diğer bir örnek, HTTP istek kaçakçılığı adı verilen
        bir saldırı türüdür.
    

      
    Bu belge HTTP istek kaçakçılığını derinliğine incelenmesi için uygun
        yer değildir (böyle kaynaklara arama motorunuzla erişebilirsiniz).
        Bununla birlikte, vekil tarafından kaynak sunucudan alınan içeriği
        tamamen denetim altına almak amacıyla kaynak sunucudaki bir açığı
        istismar etmeye yönelik bir dizi istek yapılabileceğinin olasılık
        dahilinde olduğunu bilmenizde yarar vardır.
    
    

    
    Hizmet Reddi / Önbelleğin Engellenmesi
    
      

      
    Vary mekanizması aynı URL'nin çok sayıda sürümünün yan yana
        önbelleklenmesini mümkün kılar. İstemci tarafından sağlanan başlık
        değerlerine bağlı olarak, önbellek istemciye gönderilecek doğru yanıtı
        bulacaktır. Normal kullanımda olası değerlerin çok geniş olduğunun
        bilindiği durumda bir başlığı (örn, User-Agent)
        değişikliğe uğratma çabası bu mekanizmayı bir sorun haline getirebilir.
        Sitenin tanınırlığına bağlı olarak aynı URL'nin binlerce hatta
        milyonlarca önbellek girdisi oluşabilir ve bunlar önbellekteki diğer
        girdilerin yerini alabilir.
    

      
    Diğer yandan, belli bir özkaynağın URL'sinin her istekte
      değiştirilmesi ihtiyacı ortaya çıkabilir. Bu normalde URL dizgesine bir
      "cachebuster" dizgesi eklenerek yapılır. Bu içerik sunucu tarafından
      anlamlı bir tazelik ömrüyle önbelleklenebilir olarak imlenmişse bu
      girdiler kısa zamanda önbellekteki meşru girdilerin yerini alabilir.
      mod_cache modülü bunun önlenmesi için CacheIgnoreURLSessionIdentifiers
      yönergesine sahipse de bu yönerge, yoldaki vekillerin veya tarayıcı
      önbelleklerinin aynı hizmet reddi saldırısına maruz kalmamaları için
      dikkatle kullanılmalıdır.

    d'informations X509 à propos de son propriétaire (appelé sujet/subject)
    et de l'Autorité de Certification
      (Certification Authority) ou CA signataire (appelée
      le fournisseur/issuer), ainsi que la
      clé publique (public
      key) du propriétaire et la
      signature de la CA. Les entités du réseau vérifient ces signatures
      en utilisant les certificats des Autorités de Certification.

      certificat.
    
      Voir : chiffrement SSL/TLS
    
    

    
    Directive
    
    
    Une commande de configuration qui contrôle un ou plusieurs aspects du
    comportement d'Apache.  Les directives sont placées dans le Fichier de configuration
    
    Voir : Index des directives
    
    


    Directive de configuration
	(Configuration Directive)
    
    
    Voir : Directive
    

    
    En-tête (Header)
    
    
    La partie de la requête et de la réponse
    HTTP qui est envoyée avant le contenu
    proprement dit, et contient des méta-informations décrivant le contenu.
    
    

    
    Expression Rationnelle
    (Regular Expression)
      (Regex)
    
    
    Une méthode pour décrire un modèle sous forme de texte - par exemple,
    "tous les mots qui commencent par la lettre A" ou "tous les numéros de
    téléphone à 10 chiffres" ou encore "Toutes les phrases contenant 2 virgules,
    et aucun Q majuscule". Les expressions rationnelles sont très utiles dans
    Apache car elles vous permettent d'appliquer certains attributs à des
    ensembles de fichiers ou ressources avec une grande flexibilité
      - par exemple, tous les fichiers .gif et .jpg situés dans tout répertoire
      nommé "images", pourraient être enregistrés comme
      "/images/.*(jpg|gif)$".  Lorsque l'on utilise des
      expressions rationnelles pour la substitution de chaînes, les
      variables spéciales $1 ... $9 contiennent des références arrières
      vers les parties regroupées (entre parenthèses) de l'expression
      qui correspond. La variable spéciale $0 contient une référence
      arrière vers l'ensemble de l'expression qui correspond. Pour
      insérer un caractère littéral "dollar" dans la chaîne de
      remplacement, il faut l'échapper avec un anti-slash. Pour des
      raisons historiques, la variable & peut être utilisée en tant
      qu'alias de $0 dans certains cas, mais ceci n'est plus possible
      depuis la version 2.3.6. Apache utilise les Expressions
      Rationnelles Compatibles avec Perl fournies par la librairie PCRE. Vous trouverez plus
      d'information à propos de la syntaxe des expressions rationnelles
      PCRE sur ce site, ou dans le Wikipedia de la PCRE.
  
    

    
    
    Fichier de configuration
    (Configuration File)
    
    
    Un fichier texte contenant des
    Directives
      qui contrôlent la configuration d'Apache.
    
      Voir : Fichiers de configuration
    
    

    
    Filtre (Filter)
    
    
    Un traitement appliqué aux données envoyées ou reçues par le serveur.
      Les filtres en entrée traitent les données envoyées au serveur par le
      client, alors que les filtres en sortie traitent les documents sur le
      serveur avant qu'ils soient envoyés au client.
      Par exemple, le filtre en sortie
      INCLUDES
      traite les documents pour les
      Server Side Includes (Inclusions côté Serveur)
      .
    
      Voir : Filtres
    
    


    Gestionnaire (Handler)
    
    
    Une représentation interne à Apache de l'action à entreprendre
    quand un fichier est appelé. En général, les fichiers ont des gestionnaires
    implicites, basés sur le type de fichier. Normalement, tous les
    fichiers sont directement servis par le serveur, mais certains
    types de fichiers sont "gérés" séparément.  Par exemple, le gestionnaire
      cgi-script désigne les fichiers qui doivent être traités
      comme CGIs.
    
      Voir : Utilisation des gestionnaires d'Apache
    
    

    
    Hachage (Hash)
    
    
    Un algorithme mathématique à sens unique, irréversible, générant une
    chaîne de longueur fixe à partir d'une autre chaîne de longueur quelconque.
    Des chaînes différentes en entrée vont normalement produire des chaînes
    différentes en sortie (selon la fonction de hachage).
    
    

    
    Hébergement Virtuel
    (Virtual Hosting)
    
  
    Servir des sites web multiples en utilisant une seule instance d'Apache.
  Les Hôtes virtuels basés sur IP différencient les sites web en se
  basant sur leur adresse IP, alors que les
  Hôtes virtuels basés sur le nom utilisent uniquement le nom d'hôte
  et peuvent en conséquence héberger de nombreux sites avec la même
  adresse IP.
    
    Voir la Documentation des Hôtes Virtuels d'Apache
  
    


    
    .htaccess
    
    
    Un fichier de configuration
    placé à un certain niveau de l'arborescence du site web, et appliquant des
    directives de configuration au
    répertoire dans lequel il est placé, ainsi qu'à tous ses sous-répertoires.

    Une fonctionnalité SSL permettant de spécifier le
    nom du serveur désiré dans le message initial de la
    négociation SSL, de façon à ce que le serveur web
    puisse choisir la bonne configuration de serveur virtuel à
    utiliser pendant le déroulement de la négociation SSL.
    Cette fonctionnalité a été ajoutée
    à SSL lorsque sont apparues les extensions TLS, RFC 3546.
    
      Voir la FAQ SSL
      et la RFC 3546

Localisation de Ressource Uniformisée
(Uniform Resource Locator)
       (URL)
    
  
    Le nom/adresse d'une ressource sur l'Internet.  Il s'agit du terme
  informel commun pour ce qui est formellement défini comme 
      Identificateur de Ressource Uniformisé.
    Les URLs sont généralement construites selon un schéma, comme

    Mandataire (Proxy)
    
    
    Un serveur intermédiaire qui se situe entre le client et le
    serveur d'origine.
    Il prend en compte les requêtes des clients, les transmet au serveur
    d'origine, puis renvoie la réponse du serveur d'origine au client.
    Si plusieurs clients demandent le même contenu, le mandataire peut l'extraire
    de son cache, plutôt que le demander au serveur d'origine
    à chaque fois, ce qui réduit le temps de réponse.
    
      Voir : mod_proxy
    
    

    
    Mandataire inverse
    (Reverse Proxy)
    
  
    Un serveur mandataire qui est vu du client
    comme un serveur d'origine.  Ceci peut s'avérer utile pour
    dissimuler le serveur d'origine réel au client pour des raisons de sécurité,
    ou pour répartir la charge.
  
    

    
    Méthode (Method)

    ou d'exclure.  Les modules qui sont compilés dans le binaire
    httpd sont appelés modules statiques, alors
    que les modules qui existent séparément et peuvent être chargés
    optionnellement à l'exécution sont appelés
      modules dynamiques ou DSOs.
      Les modules qui sont inclus par défaut sont appelés
      modules de base. De nombreux modules disponibles pour Apache
      ne se trouvent pas dans l'archive
      du Serveur HTTP Apache .  Il sont appelés
      modules tiers.

      entièrement qualifié.
    
    

    
    
    Nombre Magique des Modules
    (Module Magic Number)
      (MMN)
    
    
    Le Nombre Magique des Modules est une constante définie dans le code
    source d'Apache et associée à la compatibilité binaire des modules.
    Sa valeur est modifiée quand des structures internes d'Apache, des appels
    de fonctions et d'autres parties significatives de l'API sont modifiées
    de telle façon que la compatibilité binaire ne peut plus être garantie.
    En cas de changement de MMN, tous les modules tiers doivent être au
    moins recompilés, et parfois même légèrement modifiés afin de pouvoir
    fonctionner avec la nouvelle version d'Apache.

    此翻译可能过期。要了解最近的更改，请阅读英文版。
    

    
    本页描述 Apache 处理器的用法。
    
  
    


    top
    

    

    什么是处理器
    
    
    
    相关模块相关指令
    


    
    “处理器”是当文件被调用时，Apache 要执行的动作的内部表示形式。
    一般来说，每个文件都有基于其文件类型的隐式处理器。通常的文件会被
    服务器简单处理，但是某些文件类型会被分别“处理”。
    

    
    处理器也可以被基于扩展名或位置来明确配置。它们都很有用，这不仅
    因为它是优雅的方案，而且还允许类型与处理器关联到文件
    (参见文件与多个扩展名)。
    

    
    处理器可以编译到服务器中，或者包含在模块中，它们还可以被 Action 指令增加。标准发行版中内置的处理器有:
    

    
      
      
    • default-handler: 使用
      default_handler() 发送文件，它是用来处理静态内容的处理器(核心)。
      • 

      
    • send-as-is: 直接发送，不增加 HTTP 头(mod_asis)。
      • 

      
    • cgi-script: 按 CGI 脚本处理(mod_cgi)。
      • 

      
    • imap-file: 按 imagemap 规则处理(mod_imagemap)。
      • 

      
    • server-info: 取得服务器配置信息(mod_info)。
      • 

      
    • server-status: 取得服务器状态报告(mod_status)。
      • 

      
    • type-map: 用于内容协商，按类型映射文件处理(mod_negotiation)。
      • 
    
    
  
    top
    

    

    例子
    
    

    
    使用 CGI 脚本修改静态内容
    
      

      
    下面的指令将会使具有html扩展名的文件，触发 CGI 脚本footer.pl的执行。
    

      
    
        Action add-footer /cgi-bin/footer.pl
    
        AddHandler add-footer .html
      
    

      
    于是 CGI 负责发送请求的文档(PATH_TRANSLATED 环境变量指向它)，按照需要作出  and making
      whatever modifications or additions are desired.
    

    
    
    含有 HTTP 头的文件
    
      

      
    下面的指令会启用
      send-as-is 处理器，用于包含自己的 HTTP 的文件。不管什么扩展名，
      所有位于 /web/htdocs/asis/ 目录的文件会被
      send-as-is 处理器处理。
    

      
    
        <Directory /web/htdocs/asis>
    
        SetHandler send-as-is
    
        </Directory>
      
    

    
  
    top
    

    

    对程序员的说明
    
    

    
    为了实现处理器特性，增加了需要使用的 Apache API。
    特别的，结构 request_rec 增加了新成员:
    

    
    
      char *handler
    
    

    
    如果你想要模块实现处理器，只需要在在处理请求，调用 invoke_handler
    之前，将 r->handler 指向处理器名称。处理器的实现与以前一样，只是用处理器名称取代了内容类型。
    虽然不是必要，处理器的命名约定是使用破折号分割的单词，没有斜杠，从而不侵入媒体类型名称空间。

    Apache normal olarak, Windows'ta bir hizmet olarak çalışır. Ayrıntılı
      bilgi için Apache HTTPD’nin bir
      hizmet olarak çalıştırılması bölümüne bakınız.
    

    
    Unix’te ise artalanda isteklere yanıt vermek için sürekli çalışan bir
      artalan sürecidir. Bu belgede httpd’nin nasıl
      çalıştırılacağı açıklanmaktadır.

    Apache Nasıl Başlatılır?
    

    
    Yapılandırma dosyasında Listen yönergesi ile öntanımlı olan port
      80 (veya 1024’ten küçük herhangi bir port) belirtilmişse Apache HTTP
      Sunucusunu başlatmak için root yetkileri gerekecektir. Sunucu başlatılıp
      günlük dosyalarını açmak gibi bazı ön hazırlık etkinliklerinde
      bulunduktan sonra istemcilerden gelen istekleri dinlemek ve yanıt vermek
      için çeşitli çocuk süreçler başlatır. Ana
      httpd süreci root kullanıcısının aidiyetinde
      çalışmasını sürdürürken çocuk süreçler daha az yetkili bir kullanıcının
      aidiyetinde çalışır. Bu işlem seçilen Çok Süreçlilik
      Modülü tarafından denetlenir.
    

    
    httpd’yi çalıştırmak için önerilen yöntem
      apachectl betiğini kullanmaktır. Bu betik,
      httpd’nin bazı işletim sistemlerinde işlevini
      gerektiği gibi yerine getirebilmesi için gereken belli ortam
      değişkenlerini ayarlar ve httpd’yi çalıştırır.
      apachectl, komut satırı argümanlarını
      httpd’ye aktarabildiğinden gerekli
      httpd seçenekleri apachectl
      betiğine komut satırı seçenekleri olarak belirtilebilir. Ayrıca,
      apachectl betiğinin içeriğini doğrudan düzenlemek
      suretiyle betiğin başlangıç satırlarındaki HTTPD
      değişkenine httpd çalıştırılabilir dosyasının doğru
      yerini ve daima mevcut olmasını istediğiniz komut satırı
      seçeneklerini belirtebilirsiniz.
    

    
    httpd çalıştırıldığında yaptığı ilk şey yapılandırma dosyası
      httpd.conf’u bulup okumaktır. Bu dosyanın yeri derleme
      sırasında belirtilmekteyse de -f komut satırı seçeneği
      kullanılarak çalıştırma sırasında belirtmek de mümkündür:
    

    
    /usr/local/apache2/bin/apachectl -f
      /usr/local/apache2/conf/httpd.conf
    

    
    Başlatma sırasında herşey yolunda giderse sunucu kendini uçbirimden
      ayıracak ve hemen ardından uçbirim, komut istemine düşecektir. Bu,
      sunucunun etkin ve çalışmakta olduğunu gösterir. Artık tarayıcınızı
      kullanarak sunucuya bağlanabilir ve DocumentRoot dizinindeki deneme sayfasını
      görebilirsiniz.
    

    top
    

    

    Başlatma Sırasındaki Hatalar
    

    
    Apache başlatma sırasında ölümcül bir sorunla karşılaşacak olursa
      çıkmadan önce sorunu açıklayan bir iletiyi konsola veya ErrorLog yönergesi ile belirtilen hata
      günlüğüne yazacaktır. En çok karşılaşılan hata iletilerinden biri
      "Unable to bind to Port ..." dizgesidir. Bu iletiye
      genellikle şu iki durumdan biri sebep olur:
    

    
      
      
    • Sunucunun, root yetkileri gerektiren bir portu kullanmak üzere root
        kullanıcısı tarafından çalıştırılmamış olması.
      • 

      
    • Aynı portu kullanan başka bir Apache Sunucusunun veya başka bir HTTP
        sunucusunun zaten çalışmakta oluşu.
      • 
    
    

    
    Bu ve diğer sorun çözme talimatları için Apache SSS’sini inceleyiniz.
    

    top
    

    

    Sistem Açılışında Başlatma
    

    
    Sunucunuzun sistem yeniden başlatıldıktan sonra çalışmasına devam
      etmesini istiyorsanız sistem başlatma betiklerinize (genellikle ya
      rc.local dosyasıdır ya da bir rc.N dizininde
      bir dosyadır) apachectl betiği için bir çağrı
      eklemelisiniz. Bu, Apache sunucunuzu root yetkileriyle başlatacaktır.
      Bunu yapmadan önce sunucunuzun güvenlik ve erişim kısıtlamaları
      bakımından gerektiği gibi yapılandırıldığından emin olunuz.
    

    
    apachectl betiği, bir standart SysV init betiği gibi
      davranacak şekilde tasarlanmıştır. start,
      restart ve stop argümanlarını kabul edebilir
      ve bunları httpd’ye uygun sinyallere dönüştürebilir.
      Bu bakımdan, çoğunlukla uygun init dizinlerinden birine
      apachectl betiği için basitçe bir bağ
      yerleştirebilirsiniz. Fakat bunu yapmadan önce betiğin sisteminizin
      gereklerini yerine getirdiğinden emin olunuz.

    Ek Bilgiler
    

    
    httpd, apachectl ve sunucuyla
      gelen diğer destek programlarının komut satırı seçenekleri hakkında ek
      bilgi  Sunucu ve Destek Programları sayfasında
      bulunabilir. Ayrıca, Apache dağıtımında bulunan tüm modüller ve bunlarla sağlanan yönergeler hakkında da belgeler
      vardır.

    Apache ofrece la posibilidad de que los webmasters puedan
    configurar las respuestas que muestra el servidor Apache cuando se
    producen algunos errores o problemas.
    

    
    Las respuestas personalizadas pueden definirse para activarse
    en caso de que el servidor detecte un error o problema.
    

    
    Si un script termina de forma anormal y se produce una respuesta
    "500 Server Error", esta respuesta puede ser sustituida por otro
    texto de su elección o por una redirección a otra URL
    (local o externa).

    Comportamiento
    
    

    
    Comportamiento anterior
    
      

      
    NCSA httpd 1.3 devolvía mensajes antiguos del error o
      problema encontrado que con frecuencia no tenían
      significado alguno para el usuario, y que no incluían en
      los logs información que diera pistas sobre las causas de
      lo sucedido.
    
    

    
    Comportamiento actual
    
      

      
    Se puede hacer que el servidor siga uno de los siguientes
      comportamientos:
    

      
      
        
    1. Desplegar un texto diferente, en lugar de los mensajes de
        la NCSA, o
      2. 

        
    2. redireccionar la petición a una URL local, o
      3. 

        
    3. redireccionar la petición a una URL externa.
      4. 
      
    

      
    Redireccionar a otra URL puede resultar de utilidad, pero
      solo si con ello se puede también pasar alguna
      información que pueda explicar el error o problema y/o
      registrarlo en el log correspondiente más claramente.
    

      
    Para conseguir esto, Apache define ahora variables de entorno
      similares a las de los CGI:
    

      
    
        REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/x-xbitmap, 
            image/jpeg
    
        REDIRECT_HTTP_USER_AGENT=Mozilla/1.1b2 (X11; I; HP-UX A.09.05 
            9000/712)
    
        REDIRECT_PATH=.:/bin:/usr/local/bin:/etc
    
        REDIRECT_QUERY_STRING=
    
        REDIRECT_REMOTE_ADDR=121.345.78.123
    
        REDIRECT_REMOTE_HOST=ooh.ahhh.com
    
        REDIRECT_SERVER_NAME=crash.bang.edu
    
        REDIRECT_SERVER_PORT=80
    
        REDIRECT_SERVER_SOFTWARE=Apache/0.8.15
    
        REDIRECT_URL=/cgi-bin/buggy.pl
      
    

      
    Tenga en cuenta el prefijo REDIRECT_.
    

      
    Al menos REDIRECT_URL y
      REDIRECT_QUERY_STRING se pasarán a la nueva
      URL (asumiendo que es un cgi-script o un cgi-include). Las otras
      variables existirán solo si existían antes de aparecer
      el error o problema. Ninguna de estas variables
      se creará si en la directiva ErrorDocument ha especificado una
      redirección externa (cualquier cosa que empiece
      por un nombre de esquema del tipo http:, incluso si
      se refiere al mismo servidor).
    
    
  
    top
    

    

    Configuración
    
    

    
    El uso de ErrorDocument
    está activado para los ficheros .htaccess cuando AllowOverride tiene el valor
    adecuado.
    

    
    Aquí hay algunos ejemplos más...
    

    
    
      ErrorDocument 500 /cgi-bin/crash-recover 
    
      ErrorDocument 500 "Sorry, our script crashed. Oh dear" 
    
      ErrorDocument 500 http://xxx/ 
    
      ErrorDocument 404 /Lame_excuses/not_found.html 
    
      ErrorDocument 401 /Subscription/how_to_subscribe.html
    
    

    
    La sintaxis es,
    

    
    
      ErrorDocument <3-digit-code> <action>
    
    

    
    donde action puede ser,
    

    
      
      
    1. Texto a mostrar. Ponga antes del texto que quiere que se
      muestre unas comillas ("). Lo que sea que siga a las comillas se
      mostrará. Nota: las comillas (") no se
      muestran.
      2. 

      
    2. Una URL local a la que se redireccionará la
      petición.
      3. 

      
    3. Una URL externa a la que se redireccionará la
      petición.
      4. 
    
    
  
    top
    

    

    Mesajes de error personalizados y redirecciones
    
    

    
    El comportamiento de Apache en cuanto a las redirecciones ha
    cambiado para que puedan usarse más variables de entorno con
    los script/server-include.
    

    
    Antiguo comportamiento
    
      

      
    Las variables CGI estándar estaban disponibles para el
      script al que se hacía la redirección. No se incluía
      ninguna indicación sobre la precedencia de la
      redirección.
    
    

    
    Nuevo comportamiento
    
      

      
    Un nuevo grupo de variables de entorno se inicializa para que
      las use el script al que ha sido redireccionado. Cada
      nueva variable tendrá el prefijo REDIRECT_.
      Las variables de entorno REDIRECT_ se crean a
      partir de de las variables de entorno CGI que existen antes de
      la redirección, se les cambia el nombre
      añadiéndoles el prefijo REDIRECT_, por
      ejemplo, HTTP_USER_AGENT pasa a ser
      REDIRECT_HTTP_USER_AGENT. Además, para esas
      nuevas variables, Apache definirá REDIRECT_URL
      y REDIRECT_STATUS para ayudar al script a seguir su
      origen. Tanto la URL original como la URL a la que es redirigida
      la petición pueden almacenarse en los logs de acceso.
    

      
    Si ErrorDocument especifica una redirección local a un
      script CGI, el script debe incluir una campo de cabeceraa
      "Status:" en el resultado final para asegurar que
      es posible hacer llegar al cliente de vuelta la condición
      de error que lo provocó. Por ejemplo, un script en Perl
      para usar con ErrorDocument podría incluir lo
      siguiente:
    

      
    
        ... 
    
        print  "Content-type: text/html\n"; 
    
        printf "Status: %s Condition Intercepted\n", $ENV{"REDIRECT_STATUS"}; 
    
        ...
      
    

      
    Si el script tiene como fin tratar una determinada
      condición de error, por ejemplo
      404 Not Found, se pueden usar los
      códigos de error y textos específicos en su lugar.
    

      
    Tenga en cuenta que el script debe incluir un campo
      de cabecera Status: apropiado (como
      302 Found), si la respuesta contiene un campo de
      cabecera Location: (para poder enviar una
      redirección que se interprete en el cliente). De otra
      manera, la cabecera
      Location: puede que no tenga efecto.

    This document describes the use of Apache's Handlers.
    
  
    


    top
    

    

    What is a Handler
    
    
    
    Related ModulesRelated Directives
    


    
    A "handler" is an internal Apache representation of the
    action to be performed when a file is called. Generally, files
    have implicit handlers, based on the file type. Normally, all
    files are simply served by the server, but certain file types
    are "handled" separately.
    

    
    Handlers may also be configured explicitly,
    based on either filename extensions or on location,
    without relation to file type. This is
    advantageous both because it is a more elegant solution, and
    because it also allows for both a type and a
    handler to be associated with a file. (See also Files with Multiple
    Extensions.)
    

    
    Handlers can either be built into the server or included in
    a module, or they can be added with the Action directive. The
    built-in handlers in the standard distribution are as
    follows:
    

    
      
      
    • default-handler: Send the file using the
      default_handler(), which is the handler used by
      default to handle static content. (core)
      • 

      
    • send-as-is: Send file with HTTP headers
      as is. (mod_asis)
      • 

      
    • cgi-script: Treat the file as a CGI
      script. (mod_cgi)
      • 

      
    • imap-file: Parse as an imagemap rule
      file. (mod_imagemap)
      • 

      
    • server-info: Get the server's
      configuration information. (mod_info)
      • 

      
    • server-status: Get the server's status
      report. (mod_status)
      • 

      
    • type-map: Parse as a type map file for
      content negotiation. (mod_negotiation)
      • 
    
    
  
    top
    

    

    Examples
    
    

    
    Modifying static content using a CGI script
    
      

      
    The following directives will cause requests for files with
      the html extension to trigger the launch of the
      footer.pl CGI script.
    

      
    Action add-footer /cgi-bin/footer.pl
AddHandler add-footer .html
    


      
    Then the CGI script is responsible for sending the
      originally requested document (pointed to by the
      PATH_TRANSLATED environment variable) and making
      whatever modifications or additions are desired.
    

    
    
    Files with HTTP headers
    
      

      
    The following directives will enable the
      send-as-is handler, which is used for files which
      contain their own HTTP headers. All files in the
      /web/htdocs/asis/ directory will be processed by
      the send-as-is handler, regardless of their
      filename extensions.
    

      
    <Directory "/web/htdocs/asis">
    SetHandler send-as-is
</Directory>
    


    
  
    top
    

    

    Programmer's Note
    
    

    
    In order to implement the handler features, an addition has
    been made to the Apache API that
    you may wish to make use of. Specifically, a new record has
    been added to the request_rec structure:
    

    
    char *handler
    


    
    If you wish to have your module engage a handler, you need
    only to set r->handler to the name of the
    handler at any time prior to the invoke_handler
    stage of the request. Handlers are implemented as they were
    before, albeit using the handler name instead of a content
    type. While it is not necessary, the naming convention for
    handlers is to use a dash-separated word, with no slashes, so
    as to not invade the media type name-space.

    This document explains some of the directives provided by
the core server which are used to configure
the basic operations of the server.

    Server Identification
    
    

    
    Related ModulesRelated Directives
    

    
    The ServerAdmin and
    ServerTokens directives
    control what information about the server will be presented
    in server-generated documents such as error messages. The
    ServerTokens directive
    sets the value of the Server HTTP response header field.
    

    
    The ServerName,
    UseCanonicalName and
    UseCanonicalPhysicalPort
    directives are used by the server to determine how to construct
    self-referential URLs. For example, when a client requests a
    directory, but does not include the trailing slash in the
    directory name, httpd must redirect the client to the full
    name including the trailing slash so that the client will
    correctly resolve relative references in the document.
    
  
    top
    

    

    File Locations
    
    

    
    Related ModulesRelated Directives
    

    
    These directives control the locations of the various files
    that httpd needs for proper operation. When the pathname used
    does not begin with a slash (/), the files are located relative
    to the ServerRoot. Be careful
    about locating files in paths which are writable by non-root users.
    See the security tips
    documentation for more details.

    Limiting Resource Usage
    
    

    
    Related ModulesRelated Directives
    

    
    The LimitRequest*
    directives are used to place limits on the amount of resources
    httpd will use in reading requests from clients. By limiting
    these values, some kinds of denial of service attacks can be
    mitigated.
    

    
    The RLimit* directives
    are used to limit the amount of resources which can be used by
    processes forked off from the httpd children. In particular,
    this will control resources used by CGI scripts and SSI exec
    commands.
    

    
    The ThreadStackSize
    directive is used with some platforms to control the stack size.

    Implementation Choices
    
    

    
    Related ModulesRelated Directives
    

    
    The Mutex directive can be used to change
    the underlying implementation used for mutexes, in order to relieve
    functional or performance problems with APR's
    default choice.

    Expressions in Apache HTTP Server
    

    

    Available Languages:  en  |

    Historically, there are several syntax variants for expressions
    used to express a condition in the different modules of the Apache
    HTTP Server.  There is some ongoing effort to only use a single
    variant, called ap_expr, for all configuration directives.
    This document describes the ap_expr expression parser.
    
    
    
    The ap_expr expression is intended to replace most other
    expression variants in HTTPD. For example, the deprecated SSLRequire expressions can be replaced
    by Require expr.

    Grammar in Backus-Naur Form notation
    
    
      
    Backus-Naur
      Form (BNF) is a notation technique for context-free grammars,
      often used to describe the syntax of languages used in computing.
      In most cases, expressions are used to express boolean values.
      For these, the starting point in the BNF is expr.
      However, a few directives like LogMessage accept expressions
      that evaluate to a string value. For those, the starting point in
      the BNF is string.
      
    

    

    expr        ::= "true" | "false"
              | "!" expr
              | expr "&&" expr
              | expr "||" expr

    Variables
    
    

    
    The expression parser provides a number of variables of the form
    %{HTTP_HOST}. Note that the value of a variable may depend
    on the phase of the request processing in which it is evaluated.  For
    example, an expression used in an <If >
    directive is evaluated before authentication is done. Therefore,
    %{REMOTE_USER} will not be set in this case.
    

    
    The following variables provide the values of the named HTTP request
    headers. The values of other headers can be obtained with the
    req function. Using these
    variables may cause the header name to be added to the Vary
    header of the HTTP response, except where otherwise noted for the
    directive accepting the expression. The req_novary
    function may be used to circumvent this
    behavior.

    Unary operators
    
    

    
    Unary operators take one argument and have the form
    "-[a-zA-Z]", i.e. a minus and one character.
    The name is case sensitive.
    Modules may register additional unary operators.
    

    
    NameDescriptionRestricted
    

    -d
        The argument is treated as a filename.
            True if the file exists and is a directoryyes
    

    -e
        The argument is treated as a filename.
            True if the file (or dir or special) existsyes
    

    -f
        The argument is treated as a filename.
            True if the file exists and is regular fileyes
    

    -s
        The argument is treated as a filename.
            True if the file exists and is not emptyyes
    

    -L
        The argument is treated as a filename.

    -F
        True if string is a valid file, accessible via all the server's
            currently-configured access controls for that path. This uses an
            internal subrequest to do the check, so use it with care - it can
            impact your server's performance!
    

    -U
        True if string is a valid URL, accessible via all the server's
            currently-configured access controls for that path. This uses an
            internal subrequest to do the check, so use it with care - it can
            impact your server's performance!
    

    -A
        Alias for -U
    

    -n
        True if string is not empty
    

    -z
        True if string is empty
    

    -T
        False if string is empty, "0", "off",
            "false", or "no" (case insensitive).

        Same as "%{REMOTE_ADDR} -ipmatch ...", but more
        efficient
        
    

    

    
    The operators marked as "restricted" are not available in some modules
    like mod_include.

    Functions
    
    

    
    Normal string-valued functions take one string as argument and return
    a string. Functions names are not case sensitive.
    Modules may register additional functions.

        Decode base64 encoded string, return truncated string if 0x00 is
            found
    

    md5
        Hash the string using MD5, then encode the hash with hexadecimal
            encoding
    

    sha1
        Hash the string using SHA1, then encode the hash with hexadecimal
            encoding
    

    file
        Read contents from a file (including line endings, when present)
        restricted
    

    filemod
        Return last modification time of a file (or 0 if file does not exist
            or is not regular file)restricted
    

    filesize
        Return size of a file (or 0 if file does not exist or is not
            regular file)restricted
    

    

    
    The functions marked as "restricted" in the final column are not 
    available in some modules like mod_include.
    

    
    The functions marked as "ordering" in the final column require some
    consideration for the ordering of different components of the server,
    especially when the function is used within the 
    <If> directive which is
    evaluated relatively early.
    
    
    
    
    Environment variable ordering
    
    When environment variables are looked up within an 
    <If> condition, it's important 
    to consider how extremely early in request processing that this 
    resolution occurs. As a guideline, any directive defined outside of virtual host 
    context (directory, location, htaccess) is not likely to have yet had a 
    chance to execute. SetEnvIf
    in virtual host scope is one directive that runs prior to this resolution
    
    
    
    
    When reqenv is used outside of <If>, the resolution will generally occur later, but the 
    exact timing depends on the directive the expression has been used within.
    
    

    
    When the functions req or http are used,
    the header name will automatically be added to the Vary header of the
    HTTP response, except where otherwise noted for the directive accepting
    the expression. The req_novary function can be used to
    prevent names from being added to the Vary header.
    

    
    In addition to string-valued functions, there are also
    list-valued functions which take one string as argument and return a
    wordlist, i.e. a list of strings. The wordlist can be used with the
    special -in operator.  Functions names are not case
    sensitive.  Modules may register additional functions.
    

    
    There are no built-in list-valued functions. mod_ssl
    provides PeerExtList.  See the description of
    SSLRequire for details
    (but PeerExtList is also usable outside
    of SSLRequire).

    Example expressions
    

    
    
    The following examples show how expressions might be used to
    evaluate requests:
    

    
    
    # Compare the host name to example.com and redirect to www.example.com if it matches
<If "%{HTTP_HOST} == 'example.com'">
    Redirect permanent "/" "http://www.example.com/"
</If>

# Force text/plain if requesting a file with the query string contains 'forcetext'
<If "%{QUERY_STRING} =~ /forcetext/">
    ForceType text/plain
</If>

# Only allow access to this content during business hours
<Directory "/foo/bar/business">
    Require expr %{TIME_HOUR} -gt 9 && %{TIME_HOUR} -lt 17
</Directory>

# Check a HTTP header for a list of values
<If "%{HTTP:X-example-header} in { 'foo', 'bar', 'baz' }">
    Header set matched true
</If>

# Check an environment variable for a regular expression, negated.
<If "! reqenv('REDIRECT_FOO') =~ /bar/">
    Header set matched true
</If>

# Check result of URI mapping by running in Directory context with -f
<Directory "/var/www">
    AddEncoding x-gzip gz
<If "-f '%{REQUEST_FILENAME}.unzipme' && ! %{HTTP:Accept-Encoding} =~ /gzip/">
      SetOutputFilter INFLATE
</If>

# Check against the client IP
<If "-R '192.168.1.0/24'">
    Header set matched true
</If>

# Function example in boolean context
<If "md5('foo') == 'acbd18db4cc2f85cedef654fccc4a4d8'">
  Header set checksum-matched true
</If>

# Function example in string context
Header set foo-checksum "expr=%{md5:foo}"

# This delays the evaluation of the condition clause compared to <If>
Header always set CustomHeader my-value "expr=%{REQUEST_URI} =~ m#^/special_path\.php$#"

    Yapılandırma dosyalarındaki
       yönergeler sunucunun tamamına uygulanacağı gibi sadece belli dizinler,
       dosyalar, konaklar veya URL’lere uygulanmakla sınırlanabilir. Bu
       belgede, yapılandırma bölümü taşıyıcılarınının veya
       .htaccess dosyalarının, yapılandırma dosyalarındaki diğer
       yönergelerin etki alanlarını değiştirtirmek için nasıl kullanılacağı
       açıklanmıştır.

    Yapılandırma Bölümü Taşıyıcılarının Türleri
    

    
    İlgili Modüllerİlgili Yönergeler
    

    
    İki temel taşıyıcı türü vardır. Taşıyıcıların çoğu her istek için
      değerlendirmeye alınır. Taşıyıcılardaki yönergeler ise sadece bu
      taşıyıcılarla eşleşen istekler için uygulanır. Diğer yandan,
      <IfDefine>,
      <IfModule> ve
      <IfVersion>
      taşıyıcıları sadece sunucu başlatılırken veya yeniden başlatılırken
      değerlendirmeye alınır. Başlatma sırasında gerektirdikleri koşullar
      sağlanıyorsa içerdikleri yönergeler tüm isteklere uygulanır. Aksi
      takdirde, içerdikleri yönergeler yok sayılır.
    

    
    <IfDefine> yönergesi
      sadece httpd komut satırında uygun parametreler
      tanımlanmışsa uygulanabilecek yönergeleri içerir. Örneğin, aşağıdaki
      yapılandırma ile tüm isteklerin diğer siteye yönlendirilebilmesi sadece
      sunucu httpd -DClosedForNow komut satırı ile başlatıldığı
      takdirde mümkün olur:
    

    
    <IfDefine ClosedForNow>
  Redirect "/" "http://otherserver.example.com/"
</IfDefine>
    


    
    <IfModule> yönergesi
      sadece belli bir modülün sunucuda kullanılabilir durumda olması halinde
      uygulanabilecek yönergeleri içerir. Modülün ya sunucuyla birlikte durağan
      olarak derlenmiş olması ya da devingen olarak derlenmiş ve yapılandırma
      dosyasında yönergeden önce o modüle ilişkin bir LoadModule satırının bulunması gerekir. Bu
      yönergeyi sadece belli bir modülün varlığının veya yokluğunun
      yapılandırma dosyanızın çalışmasını etkilememesini istediğiniz durumlarda
      kullanmalısınız. Eksik modüllerle ilgili hata iletilerini
      engellediğinden, taşıyıcı içine, her zaman çalışması istenen yönergeler
      konulmamalıdır.
    

    
    Aşağıdaki örnekte, MimeMagicFile yönergesi sadece
      mod_mime_magic modülü mevcutsa uygulanacaktır.
    

    
    <IfModule mod_mime_magic.c>
  MimeMagicFile "conf/magic"
</IfModule>
    


    
    <IfVersion>
      yönergesi sunucunun belli bir sürümünün çalıştırılması halinde
      uygulanabilecek yönergeleri içerebilmesi dışında <IfDefine> ve <IfModule> yönergeleri gibidir.
      mod_version modülü farklı httpd sürümleri ve farklı
      yapılandırmalarla büyük ağlarda çalışmayı mümkün kılmak veya sürüm
      denemeleri yapabilmek amacıyla tasarlanmıştır.
    

    
    <IfVersion >= 2.4>
  # burası sadece 2.4.0 veya daha üstü sürümlerde
  # iş görür.
</IfVersion>
    


    
    <IfDefine>,
      <IfModule> ve
      <IfVersion>
      yönergelerinin önüne "!" konularak olumsuz koşullar için uygulanabilir.
      Ayrıca, bu bölümler daha karmaşık sınırlamalar elde etmek amacıyla bir
      diğerinin içinde kullanılabilirler.

    Dosya Sistemi, Site Alanı ve Mantıksal İfadeler
    
    

    
    En sık kullanılan yapılandırma bölümü taşıyıcıları dosya sistemindeki
      veya site alanındaki belli yerlerin yapılandırmalarını değiştirmekte
      kullanılanlardır. Öncelikle, bu ikisi arasındaki farkları bilmek
      önemlidir. Dosya sistemi disklerinizin işletim sistemi tarafından size
      gösterilen halidir. Örneğin, öntanımlı kurulumda Apache httpd, Unix
      sistemlerinde  /usr/local/apache2 altındayken Windows
      sistemlerinde  "c:/Program Files/Apache Group/Apache2"
      altındadır. (Bilgi: Windows için bile, Apache httpd yapılandırma
      dosyalarında dosya yolu belirtilirken tersbölü değil normal bölü
      karakterleri kullanılır.) Site alanı ise sunucu tarafından istemciye
      sunulan dizin ağacıdır. Yani, site alanı içindeki /dir/
      dizini, Apache httpd’nin Unix üzerinde dosya sistemine öntanımlı olarak
      kurulduğu yer göz önüne alınarak, dosya sistemindeki
      /usr/local/apache2/htdocs/dir/ dizinine karşılıktır. Site
      sayfaları veritabanlarından veya başka yerlerden devingen olarak
      üretilebildiğinden site alanlarının doğrudan dosya sistemine eşlenmesi
      gerekli değildir.
    

  
    Dosya Sistemi Taşıyıcıları
    

    
    <Directory>
      ve <Files>
      taşıyıcıları, düzenli ifade karşılıkları
      ile beraber, yönergeleri dosya sisteminin parçalarına uygularlar. Bir
      <Directory> bölümü
      içindeki yönergeler belli bir dosya sistemi dizinine ve onun alt
      dizinlerine uygulanır. Aynı etki .htaccess
      dosyaları kullanılarak da sağlanabilir. Örneğin aşağıdaki
      yapılandırmada, /var/web/dir1 dizini ve alt dizinlerinde
      dizin içeriğinin listelenmesi etkin kılınmaktadır.
    

    
    <Directory "/var/web/dir1">
  Options +Indexes
</Directory>
    


    
    Bir <Files> bölümü
      içindeki yönergeler, hangi dizinde bulunduğuna bakılmaksızın ismi
      belirtilen dosyalara uygulanır. Örneğin, aşağıdaki yapılandırma
      yönergeleri yapılandırma dosyasının ana bölümüne yerleştirildiği takdirde
      gizli.html isimli dosyalara nerede bulunursa bulunsun
      erişime izin vermeyecektir.
    

    
    <Files "gizli.html">
  Require all denied
</Files>
    


    
    Dosya sisteminin belli bir yerindeki belli dosyalarla ilgili yaptırımlar
      için <Files> ve
      <Directory> bölümleri
      birlikte kullanılabilir. Örneğin, aşağıdaki yapılandırma
      /var/web/dir1/gizli.html,
      /var/web/dir1/subdir2/gizli.html,
      /var/web/dir1/subdir3/gizli.html ve
      /var/web/dir1/ altında bulunabilecek diğer tüm
      gizli.html dosyalarına erişimi yasaklar.
    

    
    <Directory "/var/web/dir1">
    
  <Files "gizli.html">
    
    Require all denied
  </Files>
    
</Directory>
    

  

  
    Site Alanı Taşıyıcıları
    

    
    <Location> yönergesi
      ve yönergenin düzenli ifade karşılığı
      site alanındaki içerik için yapılandırmayı değiştirir.  Örneğin aşağıdaki
      yapılandırma, /gizli ile başlayan URL yollarına erişimi
      engeller. Özellikle, http://siteniz.mesela.dom/gizli,
      http://siteniz.mesela.dom/gizli123 ve
      http://siteniz.mesela.dom/gizli/dir/dosya.html
      istekleri yanında /gizli ile başlayan diğer isteklere de
      uygulanır.
    

    
    <LocationMatch "^/gizli">
    Require all denied
</LocationMatch>
    


    
    Dosya sistemi ile etkileşime girmeyen herşey için
      <Location>
      yönergesi gerekir. Aşağıdaki örnekte, belli bir URL’nin
      mod_status modülü tarafından sağlanan bir dahili
      Apache eylemcisine nasıl eşlenebileceği gösterilmiştir. Bu örnek
      için dosya sisteminde server-status adında bir dosya
      veya dizin bulunması gerekli değildir.
    

    
    <Location "/server-status">
    SetHandler server-status
</Location>
    

  

  
    Site Alanında Çakışma
    
    
    Belli bölümler ve yönergeler değerlendirilirken çakışan iki URL bir URL
    olarak dikkate alınır. <Location> yönergesi için bu şöyle olurdu:
    

    
    <Location "/foo">
</Location>
<Location "/foo/bar">
</Location>
    


    
    Diğer yandan <Takma
      adlar> tam tersi eşlenir:
    

    
    Alias "/foo/bar" "/srv/www/uncommon/bar"
Alias "/foo"     "/srv/www/common/foo"
    


    
    Aynısı ProxyPass
      yönergeleri için de geçerlidir:
    

    
    ProxyPass "/special-area" "http://special.example.com" smax=5 max=10
ProxyPass "/" "balancer://mycluster/" stickysession=JSESSIONID|jsessionid nofailover=On
    

  

  
    Dosya Adı Şablonları ve Düzenli İfadeler
    
    

    
    <Directory>,
      <Files> ve
      <Location>
      yönergelerinde, Standart C kütüphanesindeki fnmatch
      işlevindeki gibi kabuk tarzı dosya ismi kalıpları kullanılabilir. "*"
      karakteri herhangi bir karakter dizisi ile eşleşirken "?" karakteri tek
      tek karakterlerle ve "[seq]" kalıbı ise seq içindeki
      her karakterle eşleşir. "/" karakteri her hangi bir kalıp karakteri ile
      eşleşmez; açıkça belirtilmesi gerekir.
    

    
    Daha esnek bir eşleşmenin gerekli olduğu durumlar için her taşıyıcının
      bir düzenli ifade karşılığı vardır. <DirectoryMatch>, <FilesMatch> ve <LocationMatch> yönergelerinde gerekli
      eşleşmeleri seçmek için perl uyumlu düzenli
      ifadelerin kullanımına izin verilir. Ayrıca, yönergelerin
      uygulanışının düzenli ifade bölümleri kullanılarak nasıl
      değiştirileceğini öğrenmek için, aşağıda, yapılandırmanın
      katıştırılmasıyla ilgili bölüme de bakınız.
    

    
    Tüm kullanıcı dizinlerine ilişkin yapılandırmayı değiştirmek için dosya
      ismi kalıpları şöyle kullanılabilirdi:
    

    
    <Directory "/home/*/public_html">
    Options Indexes
</Directory>
    


    
    Düzenli ifade bölümleri kullanarak çeşitli türlerdeki resim dosyalarına
      erişimi bir defada yasaklayabiliriz:
    

    
    <FilesMatch "\.(?i:gif|jpe?g|png)$">
    Require all denied
</FilesMatch>
    


    
    İsimli gruplar ve geriye başvurular içeren düzenli
      ifadeler ortama eklenirken ilgili isimler büyük harfli yapılır. Böylece,
      URL'lere ve dosya yolları elemanlarına ifadelerin
      içinden ve mod_rewrite gibi modüllerden başvurmak
      mümkün olur.
    


    <DirectoryMatch "^/var/www/combined/(?<SITENAME>[^/]+)">
    Require ldap-group "cn=%{env:MATCH_SITENAME},ou=combined,o=Example"
</DirectoryMatch>
    

  

  
    Mantıksal İfadeler
    
    
    <If> yönergesi bir
      mantıksal ifade olarak belirtilebilen bir kurala bağlı olarak
      yapılandırmayı değiştirebilir. Örneğin, aşağıdaki yapılandırmada,
      HTTP Referer başlığı "http://www.example.com/" ile
      başlamıyorsa erişimi yasaklar.
    

    
    <If "!(%{HTTP_REFERER} -strmatch 'http://www.example.com/*')">
    Require all denied
</If>
    

  

  
    Ne, Ne Zaman Kullanılır?
    
    
    Dosya sistemi taşıyıcıları ile site alanı taşıyıcıları arasında seçim
      yapmak aslında oldukça kolaydır. Dosya sisteminde bulunan nesnelere
      uygulanacak yönergeler için daima <Directory> veya <Files> kullanılır. Dosya sisteminde bulunmayan nesnelere
      (bir sayfanın bir veritabanı tarafından üretilmesi gibi) uygulanacak
      yönergeler için ise <Location> kullanılır.
    

    
    Dosya sistemindeki nesnelere erişimi kısıtlarken asla
      <Location>
      kullanmamak önemlidir. Bunun sebebi farklı site alanı konumlarının
      (URL’ler) aynı dosya sistemi konumuna eşlenebilmesi dolayısıyla
      kısıtlamalarınızın etrafından dolaşılabilmesine izin vermesidir.
      Örneğin, aşağıdaki yapılandırmayı ele alalım:
    

    
    <Location "/dir/">
    Require all denied
</Location>
    


    
    http://siteniz.mesela.dom/dir/ için bir istek yapılmışsa
      bu doğru çalışacaktır. Fakat dosya sistemi harf büyüklüğüne duyarsızsa
      ne olacak? Kısıtlamanız, istek
      http://siteniz.mesela.dom/DIR/
      şeklinde yapılarak kolayca geçersiz kılınabilir. Halbuki <Directory> yönergesi isteğin
      nasıl yapıldığına bakılmaksızın bu konumdan sunulan her türlü içeriğe
      uygulanacaktı. (Dosya sistemi bağlarıyla bu da aşılabilir. Sembolik
      bağlar kullanılarak aynı dizin dosya sisteminin bir çok yerine
      yerleştirilebilir. <Directory> yönergesi dosya yolunu sıfırlamaksızın sembolik
      bağları izleyecektir. Bu bakımdan, en yüksek seviyede güvenlik için uygun
      Options yönergesi ile sembolik
      bağların izlenmesi devredışı bırakılabilir.)
    

    
    Belki de siz sırf harf büyüklüğüne duyarlı bir dosya sistemi
      kullanıyorsunuz diye böyle uygulamalara ihtiyacınız olmadığını düşünüyor
      olabilirsiniz, fakat aynı site alanını çok sayıda dosya sistemi konumuna
      eşleyecek daha bir sürü yol bulunduğunu unutmayınız. Bu bakımdan dosya
      sisteminde yapacağınız kısıtlamalarda daima dosya sistemi taşıyıcılarını
      kullanmalısınız. Bununla birlikte bu kuralın da bir istisnası vardır.
      Yapılandırma kısıtlamalarının bir <Location "/"> bölümü
      içine koyulması, bu bölüme konan yönergelerin etki alanının belli bir URL
      ile sınırlı olmaması nedeniyle mükemmelen güvenlidir.
    
  

  
    Bölüm iç içeliği
    
    
    Bazı bölüm türleri başka bölüm türlerinin içinde olabilir. Bir yandan,
      <Files> bölümü
      <Directory> bölümünün
      içinde bulunabilirken diğer yandan bir <If> bölümü <Directory>, <Location> ve <Files> bölümlerinde bulunabilir fakat 
      başka bir <If> bölümünün 
      içinde bulunamaz. Bu bölümlerin düzenli ifadeli türevleri de benzer tarzda 
      davranır.
    

    
    İç içe bölümler, aynı türdeki iç içe olmayan bölümlerin sonrasına
      yerleştirilir.

      example.com sitesine erişim için vekil sunucunun
      sadece ağdaki bazı kullanıcılar tarafından kullanılabilmesini sağlayacaktır.

    Bölümler Nasıl Katıştırılır?
    

    
    Yapılandırma bölümleri belli bir sıra ile uygulanır. Yapılandırma
      yönergelerinin yorumlanışı üzerinde önemli etkilere sahip olabilmesi
      nedeniyle neyin ne zaman çalıştığını anlamak çok önemlidir.
    

    
    Yapılandırma bölümlerinin katıştırılma sırası şöyledir:
    

    
      
      
    1. <Directory> (düzenli ifadeler hariç)
      ve .htaccess aynı anda işleme sokulur
      (.htaccess ile eğer izin verilmişse <Directory> içindeki bazı
      yönergeler geçersiz kılınabileceği için).
      2. 

      
    2. <DirectoryMatch>
      (ve <Directory "~">).
      3. 

      
    3. <Files> ve
      <FilesMatch> aynı anda
      işleme sokulur.
      4. 

      
    4. <Location>
      ve <LocationMatch>
      aynı anda işleme sokulur.
      5. 

      
    5. <If>
      
      6. 
    
    

    
    Bazı önemli durumlar:
    
    
      
        
    • <Directory>
        bölümündekiler hariç, her grup, yapılandırma dosyasında bulundukları
        sıraya göre işleme sokulurlar. Örneğin, 4. grupta /foo/bar için yapılan 
        bir istek <Location "/foo/bar"> ve <Location 
        "/foo"> bölümleriyle de eşleşir ve bunlar yapılandırma 
        dosyalarında bulundukları sıraya göre değerlendirilir.
      • 
      
        
    • Yukarıda 1. grup olan <Directory> bölümü en kısa dizin elemanından en uzun 
        dizin elemanına doğru işleme sokulur. Yani, örneğin, <Directory 
        "/var/web/dir"> bölümü <Directory    
        "/var/web/dir/subdir"> bölümünden önce işleme sokulacaktır.
      • 
    
        
    • Eğer aynı dizin için birden fazla <Directory> bölümü varsa bunlar yapılandırma 
        dosyasında bulundukları sıraya göre işleme sokulurlar.
      • 
      
        
    • Include yönergeleri ile 
        yapılandırmaya dahil edilen dosyaların içerikleri Include yönergesinin bulunduğu yere konulduktan 
        sonra işleme sokulurlar.
      • 

       
    • <VirtualHost>
       bölümlerinin içindeki bölümler, sanal konak tanımı dışındaki
       karşılıklarından sonra uygulanırlar. Bu yöntemle ana sunucu 
       yapılandırmasındaki tanımlar geçersiz kılınabilir
      • 

       
    • İstek mod_proxy tarafından sunulduğu takdirde,
       <Proxy> taşıyıcısı
       işlem sırasında <Directory> taşıyıcısının yerini alır.
      • 
    
    

    
    Bazı Teknik Bilgiler
    
      Aslında, isim dönüşüm aşamasından (Aliases ve
      DocumentRoots, URL’leri dosya isimlerine eşlemek için
      kullanılırken) hemen önce uygulanan bir
      <Location>/<LocationMatch> dizisi
      vardır. Bu dizinin sonuçları isim dönüşüm aşaması tamamlandıktan sonra
      tamamen elden çıkarılır.
    
    

  
    Modüllerle 
    yapılandırma bölümleri arasındaki ilişki
    
  
    
    Yapılandırma bölümlerini okurken örneğin mod_rewrite  
      gibi belli modüllerin yönergelerinin bu bölümlere nasıl katılacağı ve  
      ne zaman nasıl işleneceği gibi sorular sıkça aklımızdan geçer. Bunun 
      belli bir yanıtı yoktur ve biraz temel bilgi gerektirir. Her httpd 
      modülü yapılandırmasını kendi yönetir ve httpd.conf içindeki 
      yönergelerinin her biri belli bir bağlamdaki bir yapılandırmayı 
      belirtir. httpd bir komutu okunduğu sırada çalıştırmaz.
    
    
    
    Çalışma anında, httpd çekirdeği geçerli isteğe hangilerinin 
      uygulanacağını belirlemek için yukarıda açıklanan sırada tanımlı 
      yapılandırma bölümlerini tekrar tekrar okur. Eşleşen ilk bölümün bu 
      istek için geçerli yapılandırmayı içerdiği varsayılır. Eğer alt 
      bölümlerden biri de eşleşmişse bu bölümlerde yönergeleri bulunan her 
      modüle yapılandırmasını iki bölüm arasında katıştırma şansı verilir. 
      Sonuç üçüncü bir yapılandırma olup işlem bütün yapılandırma bölümleri 
      değerlendirilene kadar sürer.
    
    
    
    Yukarıdaki adımların ardından HTTP isteğiyle ilgili "asıl" işlem 
      başlar: her modül ondan istenen görevleri gerçekleştirme şansına sahip 
      olur. Nasıl davranacaklarını belirlemek için kendilerinin katıştırılmış 
      son yapılandırmalarını http çekirdeğinden alabilirler.
    
    
    
    Sürecin tamamı bir örnekle görselleştirilebilir. Aşağıdaki örnekte 
      belli bir HTTP başlığını ayarlamak için mod_headers 
      modülünün Header yönergesi 
      kullanılmıştır. /example/index.html isteği için httpd 
      CustomHeaderName başlığına hangi değeri atayacaktır?
    
    
    
    <Directory "/">
    Header set CustomHeaderName bir
    <FilesMatch ".*">
        Header set CustomHeaderName yedi
    </FilesMatch>
</Directory>

<Directory "/example">
    Header set CustomHeaderName iki
</Directory>
    
    
    
      
        
    • Directory "/" eşleşir ve ilk yapılandırma 
          olarak CustomHeaderName başlığı bir 
          değeriyle oluşturulur.
      • 
        
        
    • Directory "/example" eşleşir ve 
          mod_headers modülünün koduna göre bir katıştırma 
          durumundan yeni değer eskiyi geçersiz kılacağından yeni bir 
          yapılandırma ile CustomHeaderName başlığının değeri 
          iki yapılır.
      • 
        
        
    • FilesMatch ".*" eşleşir ve başka bir 
          katıştırma fırsatı doğar: CustomHeaderName başlığının 
          değeri yedi yapılır.
      • 
        
        
    • Neticede HHP isteğinin sonraki adımlarında 
          mod_headers çağrılıp yedi değeri 
          atanmış CustomHeaderName başlığını işleme sokması 
          istenecektir. mod_headers normalde işini yapmak 
          için bu yapılandırmayı kullanacaktır. Fakat bundan, bir yönergenin  
          gerekli olmaması veya kullanımdan kaldırılması ve benzeri nedenlerle 
          yapılandırmada iptal edilmesi gibi daha karmaşık bir eylemi bir 
          modülün gerçekleştiremeyeceği anlamı çıkarılmamalıdır.
      • 
    
    

    
    Directory ile aynı katıştırma sırasından dolayı 
      bu durum .htaccess için de geçerlidir. Burada anlaşılması gereken husus, 
      Directory ve FilesMatch 
      gibi yapılandırma bölümlerinin Header veya RewriteRule gibi modüle özgü 
      yönergelerle karşılaştırılmamasıdır, çünkü bunlar farklı seviyelerde 
      işlem görür.
    
    
  

  
    Bazı Örnekler
    

    
    Aşağıdaki yapay örnekte katıştırma sırası gösterilmiştir. Hepsinin aynı
      isteğe uygulandığı varsayımıyla, bu örnekteki yönergeler A > B > C
      > D > E sırasıyla uygulanacaktır.
    

    
    <Location "/">
    E
</Location>

<Files "f.html">
    D
</Files>

<VirtualHost *>
    <Directory "/a/b">
        B
    </Directory>
</VirtualHost>

<DirectoryMatch "^.*b$">
    C
</DirectoryMatch>

<Directory "/a/b">
    A
</Directory>
    


    
    Daha somut bir örnek olarak aşağıdakini ele alalım.
      <Directory>
      bölümlerindeki erişim sınırlamaları ne olursa olsun <Location> bölümü son olarak
      değerlendirmeye alınacak ve sunucuya sınırsız erişim verecektir.
      Başka bir deyişle, katıştırma sırası önemlidir, bu nedenle dikkatli
      olmalısınız!
    

    
    <Location "/">
    Require all granted
</Location>

# Alooo!  Bu <Directory> bölümünün hiçbir hükmü yok.
<Directory "/">
    <RequireAll>
        Require all granted
        Require not host kkadam.example.com
    </RequireAll>
</Directory>

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    
    この文書は Apache がリクエストの URL から送信するファイルの
    ファイルシステム上の位置を決定する方法を説明します。

    DocumentRoot
    

    
    リクエストに対してどのファイルを送信するかを決定するときの
    Apache のデフォルトの動作は、リクエストの URL-Path (URL のホスト名と
    ポート番号の後に続く部分) を取り出して設定ファイルで指定されている
    DocumentRoot 
    の最後に追加する、というものです。ですから、
    DocumentRoot 
    の下のディレクトリやファイルがウェブから見える基本のドキュメントの木構造を
    なします。
    

    
    Apache にはサーバが複数のホストへのリクエストを受け取る
    バーチャルホスト の機能もあります。
    この場合、それぞれのバーチャルホストに対して違う
    DocumentRoot
    を指定することができます。また、mod_vhost_alias
    モジュールにより提供されるディレクティブを使って、
    送信するためのコンテンツの場所をリクエストされた IP
    アドレスやホスト名から動的に決めることもできます。
    

    top
    

    

    DocumentRoot 外のファイル
    

    
    ファイルシステム上の、
    厳密には DocumentRoot
    の下にはない部分へのウェブアクセスを許可する必要がある
    場合がよくあります。Apache はこのために複数の方法を用意しています。
    Unix システムでは、ファイルシステムの他の部分をシンボリックリンクを
    使って DocumentRoot
    の下に持ってくることができます。セキュリティ上の理由により、
    Apache は該当するディレクトリの
    Options の設定に
    FollowSymLinks か SymLinksIfOwnerMatch が
    ある場合にのみシンボリックリンクをたどります。
    

    
    代わりの方法として、Alias
    ディレクティブを使ってファイルシステムの任意の部分をウェブの空間に
    マップできます。たとえば、
    


    Alias /docs /var/web
    

    
    という設定のときは、URL
    http://www.example.com/docs/dir/file.html には
    /var/web/dir/file.html が送信されます。
    ScriptAlias も、
    対象となっているパスが CGI スクリプトとして扱われるという追加の
    効果以外は同じように動作します。
    

    
    もっと柔軟な設定が必要な状況では、
    AliasMatch ディレクティブや
    ScriptAliasMatch ディレクティブ
    を使って強力な正規表現に基づいたマッチと置換を行なうことができます。
    たとえば、
    


    ScriptAliasMatch ^/~([a-zA-Z0-9]+)/cgi-bin/(.+)
      /home/$1/cgi-bin/$2
    

    
    は http://example.com/~user/cgi-bin/script.cgi への
    リクエストを /home/user/cgi-bin/script.cgi というパスへ
    マップし、このマップの結果としてのファイルを CGI スクリプトとして
    扱います。
    

    top
    

    

    ユーザディレクトリ
    

    
    伝統的に Unix システムではユーザ user のホームディレクトリを
    ~user/ として参照できます。mod_userdir 
    モジュールはこの概念をウェブに拡張して、
    それぞれのユーザのホームディレクトリのファイルを
    以下のような URL を使ってアクセスできるようにします。
    


    http://www.example.com/~user/file.html
    

    
    セキュリティの観点から、ウェブからユーザのホームディレクトリへ
    直接アクセスできるようにすることは適切ではありません。ですから、
    UserDir ディレクティブには
    ユーザのホームディレクトリの下の、ウェブファイルの
    置かれているディレクトリを指定します。デフォルトの設定の
    Userdir public_html を使うと、上の URL は
    /home/user/public_html/file.html というようなファイルに
    マップされます。ここで、/home/user/ は
    /etc/passwd で指定されているユーザのホームディレクトリです。
    

    
    Userdir には、
    /etc/passwd にホームディレクトリの位置が書かれていない
    システムでも使うことのできる他の形式もあります。
    

    
    中にはシンボル "~" (%7e のように符号化されることが多い)
    を格好が悪いと思って、ユーザのディレクトリを表すために別の文字列の
    使用を好む人がいます。mod_userdir はこの機能をサポートしていません。
    しかし、ユーザのホームディレクトリが規則的な構成のときは、
    AliasMatch を使って望みの
    効果を達成することができます。たとえば、
    http://www.example.com/upages/user/file.html が
    /home/user/public_html/file.html にマップされるようにするには、
    以下のように AliasMatch ディレクティブを使います:
    


    AliasMatch ^/upages/([a-zA-Z0-9]+)/?(.*)
      /home/$1/public_html/$2
    

    top
    

    

    URL リダイレクション
    

    
    上の節で説明した設定用のディレクティブは Apache に
    ファイルシステムの特定の場所からコンテンツを取ってきて
    クライアントに送り返すようにします。ときには、その代わりに
    クライアントにリクエストされたコンテンツは別の URL にあることを
    知らせて、クライアントが新しい URL へ新しいリクエストを行なうように
    する方が望ましいことがあります。これはリダイレクションと
    呼ばれていて、Redirect
    ディレクティブにより実装されています。たとえば、
    DocumentRoot の下のディレクトリ
    /foo/ が新しいディレクトリ /bar/ に移動したときは、
    以下のようにしてクライアントが新しい場所のコンテンツをリクエストするように
    指示することができます:
    


    Redirect permanent /foo/
      http://www.example.com/bar/
    

    
    これは、/foo/ で始まるすべての URL-Path を、
    www.example.com サーバの /bar/ が
    /foo/ に置換されたものにリダイレクトします。
    サーバは自分自身のサーバだけでなく、どのサーバにでもクライアントを
    リダイレクトすることができます。
    

    
    Apache はより複雑な書き換えの問題のために、
    RedirectMatch ディレクティブを
    提供しています。たとえば、サイトのホームページを違うサイトにリダイレクト
    するけれど、他のリクエストはそのまま扱う、というときは以下の設定を
    使います:
    


    RedirectMatch permanent ^/$
      http://www.example.com/startpage.html
    

    
    あるいは、一時的にサイトのすべてのページを他のサイトの特定の
    ページへリダイレクトするときは、以下を使います:
    


    RedirectMatch temp .*
      http://othersite.example.com/startpage.html
    

    top
    

    

    リバースプロキシ
    


    Apache は遠隔地にあるドキュメントをローカルのサーバの URL 空間に
持ってくることもできます。この手法はリバースプロキシと呼ばれています。
ウェブサーバが遠隔地のドキュメントを取得してクライアントに送り返すのが
プロキシサーバの動作のように見えるからです。クライアントにはドキュメントが
リバースプロキシサーバから送られてきているように見える点が通常の
プロキシとは異なります。
    


    次の例では、クライアントが /foo/ ディレクトリの下にある
ドキュメントをリクエストすると、サーバが internal.example.com の
/bar/ ディレクトリから取得して、さもローカルサーバからの
ドキュメントのようにしてクライアントに返します。
    


    
ProxyPass /foo/ http://internal.example.com/bar/
    
ProxyPassReverse /foo/ http://internal.example.com/bar/
    
ProxyPassReverseCookieDomain internal.example.com public.example.com
    
ProxyPassReverseCookiePath /foo/ /bar/

    


    ProxyPass ディレクティブは
サーバが適切なドキュメントを取得するように設定し、
ProxyPassReverse ディレクティブは
internal.example.com からのリダイレクトがローカルサーバの
適切なディレクトリを指すように書き換えます。
同様に ProxyPassReverseCookieDomain
と ProxyPassReverseCookiePath
でバックエンド側サーバの発行した Cookie を書き換えることができます。
    

    ただし、ドキュメントの中のリンクは書き換えられない、
ということは知っておいてください。
ですから、internal.example.com への絶対パスによるリンクでは、
クライアントがプロキシサーバを抜け出して internal.example.com に
直接リクエストを送る、ということになります。
サードパーティ製モジュールの mod_proxy_html
は、HTML と XHTML 中のリンクを書き換えることができます。
    

    top
    

    

    リライトエンジン
    

    
    より一層強力な置換が必要なときは、mod_rewrite
    が提供するリライトエンジンが役に立つでしょう。
    このモジュールにより提供されるディレクティブは
    ブラウザの種類、リクエスト元の IP アドレスなどのリクエストの特徴を
    使って送り返すコンテンツの場所を決めます。さらに、mod_rewrite
    は外部のデータベースファイルやプログラムを使ってリクエストの扱い方を
    決めることもできます。リライトエンジンは上で挙げられている三つのマッピング
    すべてを行なうことができます: 内部のリダイレクト (エイリアス)、
    外部のリダイレクト、プロキシです。mod_rewrite を使う多くの実用的な例は
    URL リライトガイド
    で説明されています。
    

    top
    

    

    File Not Found
    

    
    必ず、リクエストされた URL に対応するファイルがファイルシステムに
    無いという場合が発生します。これが起こるのにはいくつかの理由があります。
    場合によっては、ドキュメントを別の場所に移動した結果であることがあります。
    この場合は、クライアントにリソースの新しい位置を知らせるために
    URL リダイレクションを使うのが最善の方法です。
    そうすることによって、リソースは新しい位置に移動しているけれども、
    古いブックマークやリンクが動作し続けるようにすることができます。
    

    
    "File Not Found" エラーのもう一つのよくある理由は、
    ブラウザへの直接入力や HTML リンクからの偶発的な URL の入力間違いです。
    Apache はこの問題を改善するために、mod_speling
    モジュール (意図的な綴り間違い)
    (訳注: 正しくは spelling) を提供しています。このモジュールが
    使用されているときは、"File Not Found" エラーを横取りして、
    似たファイル名のリソースを探します。もし一つだけ見つかった場合は
    mod_speling はクライアントに正しい位置を知らせるために HTTP リダイレクトを
    送ります。もし複数の「近い」ファイルが見つかった場合は、それら
    代替となりえるもののリストがクライアントに表示されます。
    

    
    mod_speling の非常に有用な機能は、大文字小文字を区別せずに
    ファイル名を比較するものです。これは URL と unix の
    ファイルシステムが両方とも大文字小文字を区別するものである、
    ということをユーザが知らないシステムで役に立ちます。ただし、
    時折の URL 訂正程度で済まず、mod_speling をより多く使用すると、サーバに
    さらなる負荷がかかります。すべての「正しくない」リクエストの後に
    URL のリダイレクトとクライアントからの新しいリクエストがくることに
    なりますから。
    

    
    コンテンツの位置を決めようとするすべての試みが失敗すると、
    Apache は、HTTP ステータスコード 404 (file not found) と共に
    エラーページを返します。このエラーページの外観は
    ErrorDocument 
    ディレクティブで制御され、
    カスタムエラーレスポンス で
    説明されているように、柔軟な設定を行なうことができます。

  méthode pour utiliser la version 2.4 du serveur en parallèle avec la
  version 2.2. Pour tirer parti des nouvelles fonctionnalités de la
  version 2.4, reportez-vous au document "Nouvelles fonctionnalités".
    

  
    Ce document ne décrit que les modifications intervenues entre les versions
  2.2 et 2.4. Si vous effectuez une mise à jour depuis la version 2.0, vous
  devez aussi consulter le
  document de mise
  à jour de 2.0 vers 2.2.

    Modifications des paramètres de compilation
    
    
     
    Le processus de compilation est très similaire à celui de la
     version 2.2. Dans la plupart des cas, vous pourrez utiliser votre
     ancienne ligne de commande configure (telle qu'elle
     est enregistrée dans le fichier build/config.nice
     situé dans le répertoire de compilation du serveur). Voici certains
     changements intervenus dans la configuration par défaut :
    

    
      
      
    • Les modules suivants ont été supprimés : mod_authn_default,
      mod_authz_default et mod_mem_cache. Si vous utilisiez
      mod_mem_cache sous la version 2.2, vous devez maintenant utiliser
      mod_cache_disk dans la version 2.4.
      • 

      
    • Toutes les implémentations de répartition de charge ont été
      déplacées vers des sous-modules spécifiques de mod_proxy, comme
      mod_lbmethod_bybusyness. Vous devrez compiler et
      chargés tous les modules correspondants que votre configuration
      utilise.
      • 

      
    • Le support de BeOS, TPF, et des anciennes plates-formes telles
      que A/UX, Next, et Tandem a été supprimé, car
      elles ne sont plus considérées comme maintenues.
      • 

      
    • configure: les modules dynamiques (DSO) sont compilés par
      défaut
      • 

      
    • configure: par défaut, seul un jeu de modules de base est
      chargé. Les autres directives LoadModule
      sont mises en commentaires dans le fichier de configuration.
      • 

      
    • configure: le jeu de modules "most" est compilé par défaut
      • 

      
    • configure: le jeu de modules "reallyall" ajoute les modules de
      développeur au jeu "all".
      •

    Modifications de la configuration à l'exécution
    
    

    Des changements significatifs dans la configuration de
l'autorisation, ainsi que quelques changements mineurs, peuvent
nécessiter une mise à jour des fichiers de configuration de la version
2.2 avant de les utiliser sous la version 2.4.
    

    
    Autorisation
    
      

      
    Tout fichier de configuration qui gère des autorisations devra
      probablement être mis à jour.
    

    
    Vous devez vous reporter au document Authentification, autorisation et contrôle
    d'accès, et plus particulièrement à la section Pour aller plus loin qu'une simple
    autorisation qui explique les nouveaux mécanismes permettant de
    contrôler l'ordre dans lequel les directives d'autorisation sont
    appliquées.
    

    
    Les directives qui contrôlent la manière dont les modules
    d'autorisation réagissent lorsqu'ils ne reconnaissent pas
    l'utilisateur authentifié ont été supprimées : elles comprennent les
    directives AuthzLDAPAuthoritative, AuthzDBDAuthoritative,
    AuthzDBMAuthoritative, AuthzGroupFileAuthoritative,
    AuthzUserAuthoritative et AuthzOwnerAuthoritative. Ces directives
    ont été remplacées par les directives plus explicites RequireAny, RequireNone, et RequireAll.
    

    
    Si vous utilisez mod_authz_dbm, vous devez
    mettre à jour votre configuration en remplaçant les directives du
    style Require group ... par des directives du style
    Require dbm-group ....
    

    
    Contrôle d'accès
    
      

      
    Dans la version 2.2, le contrôle d'accès basé sur le nom d'hôte
      du client, son adresse IP, ou d'autres caractéristiques de la
      requête était assuré via les directives Order, Allow, Deny, et Satisfy.
    

      
    Dans la version 2.4, ce contrôle d'accès est assuré, comme tout
      contrôle d'autorisation, par le nouveau module
      mod_authz_host. Bien que le module
      mod_access_compat soit fourni à des fins de
      compatibilité avec les anciennes configurations, les anciennes
      directives de contrôle d'accès devront être remplacées par les
      nouveaux mécanismes d'authentification.
    

      
    Mélanger anciennes et nouvelles directives
    
      
    Mélanger d'anciennes directives comme Order, Allow ou Deny avec des nouvelles comme
      Require est techniquement
      possible mais déconseillé. En effet, mod_access_compat a
      été conçu pour supporter des configurations ne contenant que des anciennes
      directives afin de faciliter le passage à la version 2.4. Les
      exemples ci-dessous vous permettront de vous faire une meilleure idée des
      problèmes qui peuvent survenir.
      
    
      
    

      
    Voici quelques exemples de contrôle d'accès avec l'ancienne et
      la nouvelle méthode :
    

      
    Dans cet exemple, il n'y a pas d'authentification et toutes les requêtes sont rejetées :
    
      
    version 2.2 :
    Order deny,allow
Deny from all
    

    
      
    version 2.4 :
    Require all denied
    

    

      
    Dans cet exemple, il n'y a pas d'authentification et toutes les requêtes sont acceptées :
    
      
    version 2.2 :
    Order allow,deny
Allow from all
    

    
      
    version 2.4 :
    Require all granted
    

    

      
    Dans l'exemple suivant, il n'y a pas d'authentification et tous les
      hôtes du domaine example.org ont l'autorisation d'accès, tous les autres
      étant rejetés :
    

      
    version 2.2 :
    Order Deny,Allow
Deny from all
Allow from example.org
    

    
      
    version 2.4 :
    Require host example.org
    

    
    
    Dans l'exemple suivant, tous les hôtes du domaine example.org
      ont l'autorisation d'accès, tous les autres sont rejetés :
    

      
    version 2.2 :
    Order Deny,Allow
Deny from all
Allow from example.org
    

    
      
    version 2.4 :
    Require host example.org
    

    

      
    Dans l'exemple suivant, le mélange d'anciennes et de nouvelles
      directives produit des résultats inattendus.
    
 
      
    Mélange d'anciennes et de nouvelles directives : RESULTAT
	INATTENDU
    DocumentRoot "/var/www/html"

<Directory "/">
    AllowOverride None
    Order deny,allow
    Deny from all
</Directory>

<Location "/server-status">
    SetHandler server-status
    Require local
</Location>

access.log - GET /server-status 403 127.0.0.1
error.log - AH01797: client denied by server configuration: /var/www/html/server-status
    

    
      
    Pourquoi httpd interdit l'accès à server-status alors que la
      configuration semble l'autoriser ? Parce que dans ce scénario de fusion de configuration, les
      directives de mod_access_compat sont prioritaires par
      rapport à celles de mod_authz_host.
    

      
    L'exemple suivant quant à lui produit un résultat conforme :
    

      
    Mélange d'anciennes et de nouvelles directives : RESULTAT
	CONFORME
    DocumentRoot "/var/www/html"

<Directory "/">
    AllowOverride None
    Require all denied
</Directory>

<Location "/server-status">
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow From 127.0.0.1
</Location>

access.log - GET /server-status 200 127.0.0.1
    

     
      
    En conclusion, même si une configuration hybride peut fonctionner,
      essayez de l'éviter lors de la mise à jour : soit conservez les anciennes
      directives, puis migrez-les vers les nouvelles ultérieurement, soit
      effectuez une migration immédiate de toutes les anciennes directives vers
      les nouvelles.  
      
          
    

    
    Dans de nombreuses configurations avec authentification où la directive
     Satisfy était définie à sa valeur par défaut
     ALL, les lignes de configuration qui désactivent le contrôle
     d'accès basé sur l'hôte sont maintenant omises :
    

      
    Version 2.2 :
    # configuration en version 2.2 qui désactive le contrôle d'accès basé sur le nom
# d'hôte pour n'utiliser que l'authentification
Order Deny,Allow
Allow from all
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    
      
    Version 2.4 :
    # Pas besoin de remplacer les directives de contrôle d'accès basées sur le nom
# d'hôte désactivées
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    

     
    Dans les configurations où l'authentification et le contrôle d'accès se
     combinaient dans un but précis, les directives de contrôle d'accès doivent
     être migrées. Dans l'exemple suivant, les requêtes qui correspondent aux
     deux critères sont acceptées :
    
      
    Version 2.2 :
    Order allow,deny
Deny from all
# ALL est la valeur par défaut de Satisfy
Satisfy ALL
Allow from 127.0.0.1
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    
      
    Version 2.4 :
    AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
<RequireAll>
  Require valid-user
  Require ip 127.0.0.1
</RequireAll>
    

    

     
    Dans les configurations où l'authentification et le contrôle d'accès se
     combinaient dans un but précis, les directives de contrôle d'accès doivent
     être migrées. Dans l'exemple suivant, les requêtes qui correspondent à
     au moins un critère sont acceptées :
    
      
    Version 2.2 :
    Order allow,deny
Deny from all
Satisfy any
Allow from 127.0.0.1
AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
Require valid-user
    

    
      
    Version 2.4 :
    AuthType Basic
AuthBasicProvider file
AuthUserFile /example.com/conf/users.passwd
AuthName secure
# Implicite : <RequireAny>
Require valid-user
Require ip 127.0.0.1
    

    

    
    
    
    Autres changements dans la configuration
    
      

      
    D'autres ajustements mineurs peuvent s'avérer nécessaires pour
      certaines configurations particulières, comme décrit ci-dessous.
    

      
      
        
    • La directive MaxRequestsPerChild a été renommée en
	MaxConnectionsPerChild;
	ce nouveau nom reflète mieux l'usage de cette directive.
	L'ancien nom est encore supporté.
      • 

	
    • La directive MaxClients a
	été renommée en MaxRequestWorkers; ce nouveau
	nom reflète mieux l'usage de cette directive. Pour les
	modules multiprocessus asynchrones, comme event, le nombre
	maximal de clients n'est pas équivalent au nombre de threads du
	worker. L'ancien nom est encore supporté.
      • 

        
    • La directive DefaultType ne produit plus aucun
	effet, si ce n'est d'émettre un avertissement si elle est
	définie à une valeur autre que none. D'autres
	directives de configuration la remplacent dans la version 2.4.
        
      • 

	
    • La valeur par défaut de la directive AllowOverride est maintenant
	None.
      • 

	
    • La valeur par défaut de la directive EnableSendfile est maintenant Off.
      • 

	
    • La valeur par défaut de la directive FileETag est maintenant "MTime Size"
	(sans INode).
      • 

        
    • mod_dav_fs: le format du fichier DavLockDB a changé pour les systèmes
	avec inodes. L'ancien fichier DavLockDB doit être supprimé dans le
	cadre de la mise à jour.
        
      • 

        
    • La directive KeepAlive
	n'accepte que les valeurs On ou Off.
	Avant, toute valeur autre que "Off" ou "0" était traitée comme
	"On".
      • 

        
    • Les directives AcceptMutex, LockFile, RewriteLock, SSLMutex,
	SSLStaplingMutex et WatchdogMutexPath ont été remplacées par la
	directive unique Mutex.
	Vous devez évaluer l'impact de ces directives obsolètes dans
	votre configuration version 2.2 afin de déterminer si elles
	peuvent être simplement supprimées, ou si elles doivent être
	remplacées par la directive Mutex.
      • 

        
    • mod_cache: la directive CacheIgnoreURLSessionIdentifiers
	effectue maintenant une correspondance exacte dans la chaîne de
	paramètres au lieu d'une correspondance partielle. Si votre
	configuration mettait en jeu des sous-chaînes comme
	sessionid pour correspondre à
	/une-application/image.gif;jsessionid=123456789,
	vous devez maintenant utiliser la chaîne de correspondance
	complète jsessionid.
        
      • 

	
    • mod_cache: le second paramètre de la
	directive CacheEnable
	ne concerne les contenus en mandat direct que s'ils débutent par
	le protocole approprié. Dans les versions 2.2 et antérieures, un
	paramètre tel que '/' concernait tous les contenus.
      • 

        
    • mod_ldap: la directive LDAPTrustedClientCert s'utilise
	maintenant exclusivement au sein d'une configuration de niveau
	répertoire. Si vous utilisez cette directive, passez en revue
	votre configuration pour vous assurer qu'elle est bien présente
	dans tous les contextes de répertoire nécessaires.
      • 

	
    • mod_filter: la syntaxe de la directive
	FilterProvider utilise
	maintenant une expression booléenne pour déterminer si un filtre
	s'applique.
        
      • 

	
    • mod_include:
            
        
            
      • L'élément #if expr utilise maintenant le
	    nouvel interpréteur d'expressions.
	    L'ancienne syntaxe peut être réactivée via la directive
	    SSILegacyExprParser.
            
        • 
            
      • Dans la portée du répertoire, une directive de
	    configuration SSI* ne provoque plus la réinitialisation à
	    leur valeur par défaut de toutes les directives SSI* de
	    niveau répertoire.
        • 
            
      
        
      • 

        
    • mod_charset_lite : l'option
	DebugLevel a été supprimée en faveur d'une
	configuration de la directive LogLevel au niveau répertoire.
        
      • 

        
    • mod_ext_filter : l'option
	DebugLevel a été supprimée en faveur d'une
	configuration de la directive LogLevel au niveau répertoire.
        
      • 

	
    • mod_proxy_scgi: certaines applications web
	ne fonctionneront plus correctement avec la nouvelle
	configuration de PATH_INFO qui est différente de
	celle de la version 2.2. La configuration
	précédente peut être
	restaurée en définissant la variable
	proxy-scgi-pathinfo.
      • 

	
    • mod_ssl: le contrôle de révocation des
	certificats basé sur les CRL doit être maintenant explicitement
	configuré via la directive SSLCARevocationCheck.
        
      • 

        
    • mod_substitute: la taille maximale d'une
	ligne est maintenant 1Mo.
        
      • 

        
    • mod_reqtimeout: si ce module est chargé, il
	définit maintenant certains temps d'attente par défaut.
      • 

	
    • mod_dumpio: la directive
	DumpIOLogLevel n'est plus supportée. Les
	données sont toujours enregistrées au niveau trace7
	de LogLevel
      • 

        
    • Jusqu'à la version 2.2, sur les plateformes de style Unix, 
	les commandes de redirection des logs définies via ErrorLog ou CustomLog étaient invoquées
	en utilisant /bin/sh -c. A
	partir de la version 2.4, les commandes de redirection des logs
	sont exécutées directement. Pour retrouver l'ancien
	comportement, voir la documentation
	sur la redirection des logs
      • 

    
    
    
  
    top
    

    

    Changements divers
    
    

    
      
      
    • mod_auto_index: extrait maintenant les titres
      et affiche la description pour les fichiers .xhtml qui étaient
      jusqu'alors ignorés.
      • 

      
    • mod_ssl : le format par défaut des variables
      *_DN a changé. Il est cependant encore possible
      d'utiliser l'ancien format via la nouvelle option
      LegacyDNStringFormat de la directive SSLOptions. Le protocole SSLv2 n'est
      plus supporté. Les directives SSLProxyCheckPeerCN et
      SSLProxyCheckPeerExpire
      sont maintenant définies par défaut à On, et les requêtes mandatées
      vers des serveurs HTTPS possèdant des certificats non conformes ou
      périmés échoueront donc avec un code d'erreur 502 (Bad gateway).
      • 

      
    • htpasswd utilise maintenant par défaut les
      condensés MD5 sur toutes les plates-formes.
      • 

      
    • La directive NameVirtualHost n'a plus aucun effet, si
      ce n'est l'émission d'un avertissement. Toute combinaison
      adresse/port apparaissant dans plusieurs serveurs virtuels est
      traitée implicitement comme un serveur virtuel basé sur le nom.
      
      • 

      
    • mod_deflate n'effectue plus de compression
      s'il s'aperçoit que la quantité de données ajoutée par la
      compression est supérieure à la quantité de données à compresser.
      
      • 

      
    • Les pages d'erreur multilingues de la version 2.2.x ne
      fonctionneront qu'après avoir été corrigées pour
      respecter la nouvelle syntaxe de l'élément #if expr=
      du module mod_include, ou si la directive
      SSILegacyExprParser a
      été activée pour le répertoire contenant les pages d'erreur.
      
      • 

      
    • La fonctionnalité fournie par mod_authn_alias
      dans les précédentes versions (en fait la directive
      AuthnProviderAlias)
      est maintenant fournie par mod_authn_core.  
      
      • 

      
    • Les directives RewriteLog et RewriteLogLevel ont été
      supprimées. Leur fonctions sont maintenant assurées par la
      directive LogLevel qui permet de définir
      un niveau de journalisation approprié pour le module
      mod_rewrite. Voir aussi la section journalisation de
      mod_rewrite.

    Modules tiers
    
    

	
    Tous les modules tiers doivent être recompilés pour la
	version 2.4 avant d'être chargés.
    

    
    De nombreux modules tiers conçus pour la version 2.2
    fonctionneront sans changement avec le serveur HTTP Apache
    version 2.4. Certains nécessiteront cependant des modifications ; se
    reporter à la vue d'ensemble Mise à jour de l'API.

    Problèmes de mise à jour courants
    
    
    
    • Erreurs au démarrage :
    
        
      
      • Invalid command 'User', perhaps misspelled or defined by
      a module not included in the server configuration - chargez
      le module mod_unixd
        • 

      
      • Invalid command 'Require', perhaps misspelled or defined
      by a module not included in the server configuration, ou
      Invalid command 'Order', perhaps misspelled or defined by a
      module not included in the server configuration - chargez
      le module mod_access_compat, ou mettez à jour
      vers la version 2.4 les directives d'autorisation.
        • 

      
      • Ignoring deprecated use of DefaultType in line NN of
      /path/to/httpd.conf - supprimez la directive DefaultType et remplacez-la par les
      directives de configuration appropriées.
        • 

      
      • Invalid command 'AddOutputFilterByType', perhaps misspelled 
      or defined by a module not included in the server configuration
       - la directive AddOutputFilterByType qui était
      jusqu'alors implémentée par le module core, l'est maintenant par
      le module mod_filter, qui doit donc être chargé.
        • 

    
      • 
    
    • Erreurs de traitement des requêtes :
    
        
      
      • configuration error:  couldn't check user: /path -
      chargez le module mod_authn_core.
        • 
      
      • Les fichiers .htaccess ne sont pas traités -
      Vérifiez la présence d'une directive AllowOverride appropriée ; sa valeur par
      défaut est maintenant None.

    権限が必要になりますが、
    これはこの特権ポートにバインドするためです。
    起動して、一度ログファイルを開くといった準備のための
    動作を幾つか実行した後は、クライアントからのリクエストに対する
    listen と応答を実際に行う子プロセスを起動します。
    メインの httpd プロセスは root 権限で走り続けますが、
    子プロセスはもっと低い権限で走ります。
    これは選択したマルチプロセッシングモジュールで制御されます。
    

    
    推奨の httpd 実行プログラムの起動方法は、
    apachectl
    制御スクリプトを使用する方法です。このスクリプトは、httpd 
    がオペレーティングシステム上で正常に動作するように必要な環境変数を
    適切に設定して、httpd バイナリを起動します。
    apachectl はどんなコマンドライン引数も通過させますので、
    httpd のどのコマンドラインオプションも
    apachectl のオプションとして使用できます。
    また、apachectl スクリプトを直接編集し、
    スクリプト先頭付近の HTTPD 変数を変更することで、
    httpd バイナリの正しい位置を指定したり、常に
    付加させるコマンドライン引数を指定したりすることができます。
    

    
    httpd が起動されてまず最初にすることは、
    設定ファイル
    httpd.conf の位置を特定して読み込むことです。
    このファイルの位置はコンパイル時に設定されますが、実行時に
    -f コマンドラインオプションを使って
    位置を指定することもできます。例えば次のようにです。
    


    /usr/local/apache2/bin/apachectl -f
      /usr/local/apache2/conf/httpd.conf
    

    
    スタートアップが万事上手くいったら、サーバはターミナルから
    切り離されて、コマンドプロンプトが即座に戻ってくるでしょう。
    これはサーバが起動している状態を示しています。
    その後はブラウザでサーバに接続して、
    DocumentRoot
    ディレクトリのテストページを見ることができるでしょう。
    

    top
    

    

    起動時のエラー
    

    
    Apache は、起動時に致命的な問題に遭遇すると、
    終了する前に、コンソールか
    ErrorLog
    のどちらかに問題を記述したメッセージを出力します。
    最もよくあるエラーメッセージは
    「Unable to bind to Port ...」
    です。このメッセージは普通は次のどちらかが原因です。
    

    
      
      
    • root でログインしていない時に、
      特権ポートでサーバを起動しようとした。
      • 

      
    • 同じポートに既にバインドされている Apache
      がもう一つあるときや他のウェブサーバが存在している時に、
      サーバを開始しようとした。
      • 
    
    

    
    より多くの問題解決の方策の説明は、
	Apache FAQ をご覧下さい。
    

    top
    

    

    ブート時の起動
    

    
    システムがリブートした後でも
    サーバが実行され続けるようにしたい場合は、
    apachectl
    を呼び出すものをシステムスタートアップファイル
    (通常 rc.local や rc.N
    内のファイル) に追加しなければなりません。
    この方法では Apache を root 権限で起動します。
    これをする前に、セキュリティやアクセス制限が
    適切に設定されていていることを確認してください。
    

    
    apachectl スクリプトは通常は、標準的な SysV init 
    スクリプトとして動作するように設計されています。
    start, restart, stop
    といった引数をとって、httpd 
    への適切なシグナルに変換します。
    ですから、通常は単に適切な init ディレクトリ内から
    apachectl へリンクすることができます。しかし、
    念のためシステムの要求に合致していることを確認してください。

    httpd や
    apachectl、サーバに含まれていたその他補助プログラムの、
    コマンドラインオプションに関する追加情報は、

    Core Enhancements
    
    
    
    
      
    Run-time Loadable MPMs
    
      
    Multiple MPMs can now be built
      as loadable modules at compile time.
      The MPM of choice can be configured at run time via LoadModule directive.
    

      
    Event MPM
    
      
    The Event MPM is no longer experimental
      but is now fully supported.
    

      
    Asynchronous support
    
      
    Better support for asynchronous read/write for supporting MPMs and
      platforms.
    

      
    Per-module and per-directory LogLevel configuration
    
      
    The LogLevel can now be
      configured per module and per directory.  New levels trace1
      to trace8 have been added above the debug log
      level.
    

      
    Per-request configuration sections
    
      
    <If>,
          <ElseIf>,
          and <Else>
          sections can be used to set the configuration based on per-request
          criteria.
    

      
    General-purpose expression parser
    
      
    A new expression parser allows to specify
          complex conditions using a common syntax
          in directives like
          SetEnvIfExpr,
          RewriteCond,
          Header,
          <If>,
          and others.
      
    

      
    KeepAliveTimeout in milliseconds
    
      
    It is now possible to specify KeepAliveTimeout in milliseconds.
      
    

      
    NameVirtualHost directive
    
      
    No longer needed and is now deprecated.
    

      
    Override Configuration
    
      
    The new AllowOverrideList
          directive allows more fine grained control which directives are
          allowed in .htaccess files. 
    

      
    Config file variables
    
      
    It is now possible to Define
          variables in the configuration, allowing a clearer representation
          if the same value is used at many places in the configuration.
      
    

      
    Reduced memory usage
    
      
    Despite many new features, 2.4.x tends to use less memory than
      2.2.x.

    top
    

    

    Module Enhancements
    
    
    
    
      
    mod_ssl
    

      
    mod_ssl can now be configured to use an
      OCSP server to check the validation status of a client
      certificate.  The default responder is configurable, along with
      the decision on whether to prefer the responder designated in
      the client certificate itself.
    

      
    mod_ssl now also supports OCSP stapling, where the
      server pro-actively obtains an OCSP verification of its certificate and
      transmits that to the client during the handshake. 
    

      
    mod_ssl can now be configured to share SSL Session
      data between servers through memcached
    

      
    EC keys are now supported in addition to RSA and DSA.
    

      
    Support for TLS-SRP (available in 2.4.4 and later).
    

      
    mod_proxy
    

      
    The ProxyPass directive
      is now most optimally configured within a
      Location or
      LocationMatch
      block, and offers a significant performance advantage over the traditional
      two-parameter syntax when present in large numbers.
    
      
    The source address used for proxy requests is now configurable.
    
      
    Support for Unix domain sockets to the backend (available in 2.4.7
      and later).
    

      
    mod_proxy_balancer
    

      
    More runtime configuration changes for BalancerMembers via balancer-manager
    

      
    Additional BalancerMembers can be added at runtime via balancer-manager
    

      
    Runtime configuration of a subset of Balancer parameters
    

      
    BalancerMembers can be set to 'Drain' so that they only respond to existing sticky
      sessions, allowing them to be taken gracefully offline.
    

      
    Balancer settings can be persistent after restarts.
    

      
    mod_cache
    

      
    The mod_cache CACHE filter can be optionally inserted
      at a given point in the filter chain to provide fine control over caching.
      
    

      
    mod_cache can now cache HEAD requests.
    

      
    Where possible, mod_cache directives can now be set
      per directory, instead of per server.
    

      
    The base URL of cached URLs can be customised, so that a cluster of
      caches can share the same endpoint URL prefix.
    

      
    mod_cache is now capable of serving stale cached
      data when a backend is unavailable (error 5xx).
    

      
    mod_cache can now insert HIT/MISS/REVALIDATE into
      an X-Cache header.
    

      
    mod_include
    
      
    Support for the 'onerror' attribute within an 'include' element,
      allowing an error document to be served on error instead of the default
      error string.
    

      
    mod_cgi, mod_include,
          mod_isapi, ...
    
      
    Translation of headers to environment variables is more strict than
      before to mitigate some possible cross-site-scripting attacks via header
      injection. Header names containing invalid characters (including underscores)
      are no longer converted to environment variables. Environment Variables
      in Apache has some pointers on how to work around broken legacy
      clients which require such headers. (This affects all modules which
      use these environment variables.)
    

      
    mod_authz_core Authorization Logic Containers
    

      
    Advanced authorization logic may now be specified using the
          Require directive
          and the related container directives, such as
          <RequireAll>.
    

      
    mod_rewrite
    
      
    mod_rewrite adds the [QSD]
          (Query String Discard) and [END] flags for
          RewriteRule to
          simplify common rewriting scenarios.
    
      
    Adds the possibility to use complex boolean expressions in RewriteCond.
    
      
    Allows the use of SQL queries as RewriteMap functions.
    

      
    mod_ldap, mod_authnz_ldap
    
      
    mod_authnz_ldap adds support for nested groups.
    
      
    mod_ldap adds
          LDAPConnectionPoolTTL,
          LDAPTimeout, and
          other improvements in the handling of timeouts.
          This is especially useful for setups where a
          stateful firewall drops idle connections to the LDAP server.
    
      
    mod_ldap adds
          LDAPLibraryDebug to log
          debug information provided by the used LDAP toolkit.
    

      
    mod_info
    
      
    mod_info can now dump the pre-parsed configuration
          to stdout during server startup.
    

      
    mod_auth_basic
    
      
    New generic mechanism to fake basic authentication (available in
      2.4.5 and later).
    

    
    
  
    top
    

    

    Program Enhancements
    
    
    
    
        
    fcgistarter
    
        
    New FastCGI daemon starter utility
    

        
    htcacheclean
    
        
    Current cached URLs can now be listed, with optional metadata
        included.
    
        
    Allow explicit deletion of individual cached URLs from the
        cache.
    
        
    File sizes can now be rounded up to the given block size, making
        the size limits map more closely to the real size on disk.
    
        
    Cache size can now be limited by the number of inodes, instead
        of or in addition to being limited by the size of the files on
        disk.
    

        
    rotatelogs
    
        
    May now create a link to the current log file.
    
        
    May now invoke a custom post-rotate script.
    

        
    htpasswd, htdbm
    
        
    Support for the bcrypt algorithm (available in 2.4.4 and later).
        
    
    
    
  
    top
    

    

    Documentation
    
    
    
    
        
    mod_rewrite
    
        
    The mod_rewrite documentation has been
        rearranged and almost completely rewritten, with a focus on
        examples and common usage, as well as on showing you when other
        solutions are more appropriate. The Rewrite
        Guide is now a top-level section with much more detail and
        better organization.
    

        
    mod_ssl
    
        
    The mod_ssl documentation has been greatly
        enhanced, with more examples at the getting started level, in
        addition to the previous focus on technical details.
    

        
    Caching Guide
    
        
    The Caching Guide has been rewritten
        to properly distinguish between the RFC2616 HTTP/1.1 caching
        features provided by mod_cache, and the generic
        key/value caching provided by the socache
        interface, as well as to cover specialised caching provided by
        mechanisms such as mod_file_cache.

    Module Developer Changes
    
    
    
    
      
    Check Configuration Hook Added
    

      
    A new hook, check_config, has been added which runs
          between the pre_config and open_logs
          hooks.  It also runs before the test_config hook
          when the -t option is passed to
          httpd.  The check_config hook
          allows modules to review interdependent configuration directive
          values and adjust them while messages can still be logged to the
          console.  The user can thus be alerted to misconfiguration problems
          before the core open_logs hook function redirects
          console output to the error log.
    

      
    Expression Parser Added
    

      
    We now have a general-purpose expression parser, whose API is
          exposed in ap_expr.h.  This is adapted from the
          expression parser previously implemented in
          mod_ssl.
    

      
    Authorization Logic Containers
    

      
    Authorization modules now register as a provider, via
      ap_register_auth_provider(), to support advanced authorization logic,
      such as <RequireAll>.
    

      
    Small-Object Caching Interface
    

      
    The ap_socache.h header exposes a provider-based
      interface for caching small data objects, based on the previous
      implementation of the mod_ssl session cache.
      Providers using a shared-memory cyclic buffer, disk-based dbm
      files, and a memcache distributed cache are currently
      supported.
    

      
    Cache Status Hook Added
    

      
    The mod_cache module now includes a new
      cache_status hook, which is called when the caching
      decision becomes known. A default implementation is provided
      which adds an optional X-Cache and
      X-Cache-Detail header to the response.
    
    
    

    
    The developer documentation contains a
    detailed list of API changes.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    
 
    設定ファイル中のディレクティブは
サーバ全体に適用されたり、特定のディレクトリやファイル、ホスト、URL にのみ
適用されるように制限したりすることができます。この文書は設定用のセクションの
コンテナや .htaccess ファイルを使って他の設定ディレクティブの
スコープを変更する方法を説明します。
    

    


    top
    

    

    設定用セクションコンテナの種類
    


    関連モジュール関連ディレクティブ
    


    コンテナには二つの基本となる種類があります。ほとんどのコンテナは
各リクエストに対して評価されます。その場合、コンテナ中のディレクティブは
コンテナにマッチするリクエストにのみ適用されます。一方、
<IfDefine>, 
<IfModule>, 
<IfVersion>
コンテナは
サーバの起動時と再起動時にのみ評価されます。起動時に条件が真であれば、
コンテナ中のディレクティブはすべてのリクエストに適用されます。条件が
偽であれば、コンテナ中のディレクティブは無視されます。
    


    <IfDefine> ディレクティブは
httpd コマンドラインで適切なパラメータが定義されたときにのみ
適用されるディレクティブを囲います。例えば次の設定では、サーバが
httpd -DClosedForNow を使って起動されたときだけすべての
リクエストを別のサイトにリダイレクトします:
    


    
<IfDefine ClosedForNow>
    
Redirect / http://otherserver.example.com/
    
</IfDefine>

    


    <IfModule> は
非常に似ていますが、代わりにサーバ上でモジュールが使用可能な場合にのみ
適用可能なディレクティブを囲います。モジュールはサーバに
静的に組み込まれているか、動的に組み込むようになっていて、設定ファイル中で
LoadModule の行がより前の
部分に書かれている必要があります。このディレクティブは特定のモジュールの
存在に関わらず設定ファイルが動作する必要がある場合にのみ使ってください。
常に動作して欲しいディレクティブを囲むために使うべきではありません。
存在しないモジュールに関する有用なエラーメッセージの発生を抑制してしまいますので。

    


    次の例では、mod_mime_magic があるときにのみ MimeMagicFiles ディレクティブが
適用されます。
    


    
<IfModule mod_mime_magic.c>
    
MimeMagicFile conf/magic
    
</IfModule>

    


    <IfVersion>
ディレクティブは
<IfDefine> や
<IfModule>と、
とてもよく似ていますが、稼働中のサーバのバージョンが特定のバージョンの時にのみ
適用されます。様々なバージョンの httpd を様々な設定で動作させることになる場合で、
テストスイートや巨大なネットワークでの用途を想定して、
このモジュールは設計されています。
    


    
  <IfVersion >= 2.1>
    
  
    # this happens only in versions greater or
    
    # equal 2.1.0.
    
      
  </IfVersion>

    


    <IfDefine>, 
<IfModule>,
<IfVersion> ディレクティブは
テストの前に "!" を付けることで否定の条件を適用することができます。
また、これらのセクションはより複雑な制限を課すために入れ子にすることができます。

    ファイルシステムとウェブ空間
    


    最もよく使われる設定のセクションコンテナはファイルシステムやウェブ空間の
特定の場所の設定を変更するものです。まず、この二つの違いを理解することが
大切です。ファイルシステムはオペレーティングシステムから見たディスクの内容です。
たとえば、デフォルトのインストールでは Apache は Unix ファイルシステムでは
/usr/local/apache2 に、Windows ファイルシステムでは
"c:/Program Files/Apache Group/Apache2" に存在します。
(Apache では Windows でもパスセパレータとしてスラッシュを使うことに
気をつけてください。) 対照的に、ウェブ空間はあなたのサイトを
ウェブサーバから配信されるものとして見たもので、クライアントに見えるものです。
デフォルトの Unix 上の Apache のインストールではウェブ空間の
/dir/ というパスはファイルシステムの
/usr/local/apache2/htdocs/dir/ というパスに対応します。
ウェブページはデータベースや他の場所から動的に生成することもできますので、
ウェブ空間はファイルシステムに直接マップする必要はありません。
    


    ファイルシステムコンテナ
    


    <Directory> ディレクティブと
<Files> ディレクティブ、それと
それらの正規表現版はディレクティブをファイルシステムの一部分に対して適用します。
<Directory> セクションの
中のディレクティブは指定されたディレクトリとそのすべてのサブディレクトリに
適用されます。.htaccess ファイルを
使うことでも同じ効果を得ることができます。例えば、次の設定では
/var/web/dir1 とすべてのサブディレクトリに対して
ディレクトリインデックスを行ないます。
    


    
<Directory /var/web/dir1>
    
Options +Indexes
    
</Directory>

    


    <Files> セクションの
中にあるディレクティブはどのディレクトリにあるかに関わらず、指定された名前の
すべてのファイルに適用されます。ですから例えば以下の設定ディレクティブが
設定ファイルの主セクションに書かれたときには、すべての場所の
private.html という名前のファイルへのアクセスを拒否します。
    


    
<Files private.html>
    
Order allow,deny
    
Deny from all
    
</Files>

    


    ファイルシステムの特定の場所にあるファイルを指定するために、
<Files> セクションと
<Directory> セクションを
組み合わせることができます。例えば、次の設定では
/var/web/dir1/private.html, 
/var/web/dir1/subdir2/private.html, 
/var/web/dir1/subdir3/private.html など、
/var/web/dir1/ ディレクトリの下にあるすべての
private.html へのアクセスを拒否します。
    


    
<Directory /var/web/dir1>
    
<Files private.html>
    
Order allow,deny
    
Deny from all
    
</Files>
    
</Directory>

    



    ウェブ空間コンテナ
    


    一方、<Location>
ディレクティブとその正規表現版は
ウェブ空間上の内容に対して設定を変更します。
たとえば、次の設定では /private で始まる URL パスへのアクセスを制限します。
具体的には、
http://yoursite.example.com/private,
http://yoursite.example.com/private123, 
http://yoursite.example.com/private/dir/file.html 
へのリクエストや、
他の同様に /private 文字列で始まるリクエストに
適用されます。
    


    
<Location /private>
    
Order Allow,Deny
    
Deny from all
    
</Location>

    


    <Location>
ディレクティブはファイルシステムと関係ある必要が全くありません。
たとえば次の例では、どのようにして特定の URL を
mod_statusで提供されている Apache 
内部ハンドラにマップするかを示しています。ファイルシステムに
server-status というファイルが存在する必要はありません。
    


    
<Location /server-status>
    
SetHandler server-status
    
</Location>

    



    ワイルドカードと正規表現
    


    <Directory>, 
<Files>, 
<Location> 
ディレクティブでは、 C 標準ライブラリの fnmatch のように
shell スタイルのワイルドカードキャラクタが使用できます。
"*" 文字は任意の文字列にマッチし、"?" 文字は任意の 1 文字にマッチし、
"[seq]" は seq の任意の文字にマッチします。
"/" 文字はどのワイルドカードでもマッチされません。
明示的に指定する必要があります。
    


    これより柔軟なマッチングが必要な場合は、これらのコンテナに正規表現
(regex) 版である
<DirectoryMatch>, 
<FilesMatch>, 
<LocationMatch>
があり、マッチを選択するのに perl 互換正規表現を使用できます。しかし、次の設定のマージに目を通して、
regex セクションを使用することで、ディレクティブの適用がどのように
変化するか把握しておいてください。
    


    全ユーザディレクトリの設定を変更する、非 regex
ワイルドカードセクションは次のようになります。
    


    
<Directory /home/*/public_html>
    
Options Indexes
    
</Directory>

    


    regex セクションを使用することで、画像ファイルの多くのタイプに対する
アクセスを一度に拒否できます。
    

    
<FilesMatch \.(?i:gif|jpe?g|png)$>
    
Order allow,deny
    
Deny from all
    
</FilesMatch>

    




    いつ何を使うか
    


    ファイルシステムコンテナとウェブ空間コンテナを使い分けるのは、
実際には非常に簡単です。ファイルシステムに依存する
オブジェクトにディレクティブを適応する場合は、必ず
<Directory> か
<Files>
を使用します。ファイルシステムに依存しないオブジェクト
(データベースから生成されるウェブページなど) 
にディレクティブを適用する際には、
<Location>
を使用します。
    


    ファイルシステム上のオブジェクトへのアクセスを制限するために、
<Location>
を決して使用ないようにしましょう。
同一のファイルシステム位置にマップしている、ウェブ空間位置 (URL)
が多数あって、設定した制限を迂回されてしまうかもしれないからです。
例えば次の設定を考えてみましょう。
    


    
<Location /dir/>
    
Order allow,deny
    
Deny from all
    
</Location>

    


    http://yoursite.example.com/dir/
へのリクエストでは上手く動作します。しかし大文字小文字を区別しない
ファイルシステムを使っていたらどうなるでしょう?
http://yoursite.example.com/DIR/ 
へのリクエストで簡単にアクセス制限を迂回されてしまいます。これに対して
<Directory>
ディレクティブを使用すると、どのように呼び出されたかに関わらず
その場所から提供される内容に適用されます。
(例外はファイルシステムのリンクです。シンボリックリンクを使って、
同一のディレクトリを複数のファイルシステムに設置できます。
<Directory>
ディレクティブはパス名をリセットすることなくシンボリックリンクを
辿ります。ですから、高度なセキュリティが要求される場合は、
適切に Options 
ディレクティブを使用してシンボリックリンクを無効にするべきです。)
    


    大文字小文字を区別するファイルシステムを使用しているから上記のことは
無関係だと思われるかもしれませんが、
同一のファイルシステム位置に複数のウェブ空間位置をマップする方法は、
他にいくらでもあるということを覚えていてください。
ですからできる限りファイルシステムコンテナを使用してください。
しかしながら一つだけ例外があります。
<Location /> セクションはどんな URL 
にも関わらず適用されるので、完全に安全です。
    



    top
    

    

    バーチャルホスト
    


    <VirtualHost>
コンテナは特定のホストに適用するディレクティブを格納します。
一台のマシンで複数のホストを異なる設定で提供したいときに有用です。
詳細に関してはバーチャルホストドキュメントを
ご覧下さい。
    

    top
    

    

    プロクシ
    


    <Proxy>
と <ProxyMatch>
コンテナは、特定の URL にマッチする mod_proxy
プロクシサーバを経由してアクセスしたサイトに対してのみ適用される
設定ディレクティブを格納します。例えば次の設定は、cnn.com 
ウェブサイトにアクセスするために用いられるプロクシサーバを
制限します。
    


    
<Proxy http://cnn.com/*>
    
Order allow,deny
    
Deny from all
    
</Proxy>

    

    top
    

    

    どのディレクティブが使えるの?
    


    どのタイプの設定セクションでどのディレクティブが使用できるかは、
ディレクティブの Context
を見てください。
<Directory>
で使用可能なものは全て、同様に
<DirectoryMatch>,
<Files>,
<FilesMatch>,
<Location>,
<LocationMatch>,
<Proxy>,
<ProxyMatch>
セクションで使用可能です。しかしながら幾つか例外も存在します。
    


      

    • AllowOverride ディレクティブは
<Directory>
セクションでのみ使用可能です。
      • 


    • FollowSymLinks と SymLinksIfOwnerMatch の
Options は、
<Directory>
セクションか .htaccess ファイルでのみ使用可能です。
      • 


    • Options ディレクティブは、
<Files>
と <FilesMatch>
セクションでは使用できません。
      • 

    

    top
    

    

    セクションのマージ方法
    

    
    マージの順番は以下のようになっています:
    

    
      
      
    1. <Directory> (正規表現無し) と
      .htaccess を同時に (.htaccess が許可されていれば、それが
      <Directory> を上書きします)
      
      2. 

      
    2. <DirectoryMatch>
      (と <Directory ~>
      3. 

      
    3. <Files> と
      <FilesMatch> を同時に
      4. 

      
    4. <Location> と
      <LocationMatch> を同時に
      5. 
    
    

    
    <Directory>
    以外は、それぞれのグループは設定ファイルに現れた順番に処理されます。
    <Directory> (上のグループ 1)
    はディレクトリが短いものから長いものへと処理されます。ですから、
    例えば <Directory /var/web/dir1> は
    <Directory /var/web/dir/subdir> の前に処理されます。複数の
    <Directory> セクションが
    同じディレクトリに
    適用される場合は、設定ファイル中の順番に従って処理されます。
    Include
    によって挿入された設定は 挿入しているファイルの
    Include
    ディレクティブの位置にあったかのように扱われます。
    

    
    <VirtualHost> セクション中のセクションは
    バーチャルホストの定義の外側の対応するセクションの
    後に適用されます。これによりバーチャルホストが
    メインのサーバ設定を上書きできるようなります。
    

    
    mod_proxy でリクエストが処理される場合は、
    処理順番のうち、<Directory> コンテナの部分が
    <Proxy>
    コンテナに取って代わられます。
    

    
    後のセクションのディレクティブが前のセクションのものを上書きします。
    



    技術メモ
    
      実際には、名前を変換する段階 (URL
      をファイル名にマップするために Alias や
      DocumentRoot が使用されるところ) の直前に
      <Location>/<LocationMatch>
      が行なわれます。
      これらを適用した結果は変換が終わった後に完全に捨てられます。

    

    例
    


    次はマージの順番を示すための恣意的な例になっています。
リクエスト全てに適用されるとして、本例のディレクティブは
A > B > C > D > E の順番に適用されます。
    


    
<Location />
    
E
    
</Location>
    

    
<Files f.html>
    
D
    
</Files>
    

    
<VirtualHost *>
    
<Directory /a/b>
    
B
    
</Directory>
    
</VirtualHost>
    

    
<DirectoryMatch "^.*b$">
    
C
    
</DirectoryMatch>
    

    
<Directory /a/b>
    
A
    
</Directory>
    

    

    


    もっと具体的な、次の例を考えてみましょう。
<Directory> 
セクションに設置されたアクセス制限に関わらず、
<Location>
セクションが最後に評価されて、サーバへのアクセスは制限されません。
言い換えれば、マージの順番は重要で、注意して使用してください!
    


    
<Location />
    
Order deny,allow
    
Allow from all
    
</Location>
    

    
# Woops!  This <Directory> section will have no effect
    
<Directory />
    
Order allow,deny
    
Allow from all
    
Deny from badguy.example.com
    
</Directory>

    En Windows, Apache se ejecuta normalmente como un servicio. 
        Para obtener más información, consulte
    Ejecutar Apache como un
    servicio.
    

    
    En Unix, el programa httpd se
    ejecuta como un demonio (daemon) de forma contíniua y en segundo plano
    y atiende las peticiones que le lleguen.  Este documento describe cómo
    invocar el programa httpd.
    

    


    top
    

    

    Cómo iniciar Apache
    

    
    Si el puerto especificado en la directiva Listen del fichero de
    configuración es el que viene por defecto, es decir, el
    puerto 80 (o cualquier otro puerto por debajo del 1024), entonces
    es necesario tener privilegios de usuario root (superusuario) para
    iniciar Apache, de modo que pueda establecerse una conexión a
    través de esos puertos privilegiados. Una vez que el servidor
    Apache se ha iniciado y ha completado algunas tareas preliminares,
    tales como abrir sus ficheros log, lanzará varios procesos,
    procesos hijo, que hacen el trabajo de escuchar y atender
    las peticiones de los clientes.  El proceso principal,
    httpd continúa ejecutándose con el usuario root, pero los
    procesos hijo se ejecutan con menores privilegios de usuario.
    Esto lo controla el Módulo de
    MultiProcesamiento (MPM) seleccionado.
    

    
    La forma recomendada para invocar el ejecutable
    httpd es usando el script de control 
    apachectl.  Este script fija
    determinadas variables de entorno que son necesarias para que
    httpd funcione correctamente en el sistema operativo,
    y después invoca el binario httpd.
    apachectl pasa a httpd
    cualquier argumento que se le pase a través de la línea de comandos, 
    de forma que cualquier opción de httpd puede ser usada
    también con apachectl.  Puede editar
    directamente el script apachectl y cambiar la
    variable HTTPD variable que está al principio y
    que especifica la ubicación exacta en la que está el
    binario httpd y cualquier argumento de línea de
    comandos que quiera que esté siempre presente.
    

    
    La primera cosa que hace httpd cuando es invocado
    es localizar y leer el fichero de
    configuración httpd.conf. El lugar en el que
    está ese fichero se determina al compilar, pero también
    es posible especificar la ubicación en la que se encuentra al
    iniciar el servidor Apache usando la opción de línea de
    comandos -f
    


    /usr/local/apache2/bin/apachectl -f
      /usr/local/apache2/conf/httpd.conf
    

    
    Si todo va bien durante el arranque, la sesión de terminal
    se suspenderá un momento y volverá a estar activa casi
    inmediatamente. Esto quiere decir que el servidor está activo
    y funcionando. Puede usar su navegador para conectarse al
    servidor y ver la página de prueba que hay en el directorio de
    la directiva
    DocumentRoot.

    Errores Durante el Arranque
    

    
    Si Apache encuentra una error irrecuperable durante el
    arranque, escribirá un mensaje describiendo el problema en la
    consola o en el archivo ErrorLog antes de abortar la
    ejecución. Uno de los mensajes de error más comunes es
    "Unable to bind to Port ...". Cuando se recibe este
    mensaje es normalmente por alguna de las siguientes razones:
    

    
      
      
    • Está intentando iniciar el servidor Apache en un puerto
      privilegiado (del 0 al 1024) sin haber hecho login como usuario
      root; ó bien
      • 

      
    • Está intentando iniciar el servidor Apache mientras
      está ya ejecutando Apache o algún otro servidor web en
      el mismo puerto.
      • 
    
    

    
    Puede encontrar más información sobre cómo
    solucionar problemas, en la sección de Preguntas Frecuentes de Apache.

    Iniciar Apache al Iniciar el Sistema
    

    
    Si quiere que el servidor Apache continúe su ejecución
    después de reiniciar el sistema, debe añadir una llamada
    a apachectl en sus archivos de arranque (normalmente
    rc.local o un fichero en ese directorio del tipo
    rc.N). Esto iniciará Apache como usuario
    root. Antes de hacer esto, asegúrese de que la
    configuración de seguridad y las restricciones de acceso de
    su servidor Apache están correctamente configuradas.
    

    
    El script apachectl está diseñado para
    actuar como un script estándar de tipo SysV init; puede tomar los
    argumentos start, restart, y
    stop y traducirlos en las señales apropiadas
    para httpd.  De esta manera, casi siempre puede
    simplemente enlazar apachectlcon el directorio init
    adecuado. Pero asegúrese de comprobar los requisitos exactos
    de su sistema.

    Bu belgede, bir istekte belirtilen URL’nin sunulacak dosyanın dosya
      sistemindeki yerini bulmak için Apache HTTP Sunucusu tarafından nasıl
      kullanıldığı açıklanmaktadır.

    DocumentRoot
    

    
    Yapılan bir isteğe hangi dosyanın sunulacağına karar verirken
      httpd’nin öntanımlı davranışı istek için URL yolunu (URL’den konak ismi
      ve port ayrıldıktan sonra kalan kısım) alıp bunu yapılandırma dosyasında
      DocumentRoot yönergesi ile
      belirtilen dizinin sonuna eklemektir. Bu nedenle, DocumentRoot altındaki dizinler ve dosyalar
      sitenin dışardan görünen temel belge ağacını oluştururlar.
    

    
    Örneğin, DocumentRoot yönergesine
      /var/http/html atanmış olsun.
      http://example.com/balıklar/zargana.html şeklindeki bir
      istek için istemciye /var/http/html/balıklar/zargana.html
      dosyası sunulur.
    

    
    Bir dizin istenirse (/ ile biten bir yol belirtilmesi
      durumu), sunulacak dosya DirectoryIndex yönergesinde belirtilen dosya olacaktır.
      Örneğin, DocumentRoot yukarıdaki gibi belirtimiş ve siz de
      şunu belirtmişseniz:
    

    
    DirectoryIndex index.html index.php
    

    
    http://www.example.com/fish/ isteği, httpd'nin
      /var/www/html/fish/index.html dosyasını sunmaya, bu dosya
      bulunmuyorsa /var/www/html/fish/index.php dosyasını sunmaya
      çalışmasına sebep olacaktır.
    

    
    Bu dosyaların ikisi de bulunmuyorsa sonraki adım,
      mod_autoindex yüklü ve uygun şekilde yapılandırılmışsa
      bir dizin içeriği dosyası sağlamaya çalışmak olacaktır.
    

    
    httpd ayrıca, sunucunun birden fazla konak için istek kabul etmesini
      sağlayan sanal barındırmaya da muktedirdir. Bu
      durumda her sanal konak için ayrı bir DocumentRoot belirtilebileceği gibi sunulacak içeriğin
      istekte bulunulan IP adresi veya konak ismine dayanarak devingen olarak
      saptanmasını sağlayabilen mod_vhost_alias modülüyle
      gelen yönergeler de kullanılabilir.
    

    
    DocumentRoot yönergesi
      yapılandırma dosyanızda ana sunucu için bir tane ve muhtemelen
      oluşturduğunuz her sanal konak için de birer
      tanedir.
    

    top
    

    

    Belge Kök Dizini Dışındaki Dosyalar
    

    
    Bazen dosya sisteminde doğrudan DocumentRoot altında bulunmayan dosyalara da erişim izni
      vermek gerekir. httpd’de bunu sağlamanın çeşitli yolları vardır. Unix
      sistemlerinde sembolik bağlar sayesinde dosya sisteminin farklı
      yerlerindeki dosyaları ve dizinleri DocumentRoot altındaymış gibi göstermek mümkündür.
      Options yönergesine değer olarak
      FollowSymLinks veya SymLinksIfOwnerMatch
      atanmadıkça httpd olası güvenlik açıklarına karşı öntanımlı olarak
      sembolik bağları izlemez.
    

    
    Bundan başka, dosya sisteminin farklı parçalarını belge kök dizini
      altında göstermek için Alias
      yönergesi de kullanılabilir. Örneğin,
    

    
    Alias "/belgeler" "/var/http"
    


    
    yapılandırması ile
      http://example.com/belgeler/dizin/dosya.html URL’si için
      dosya sistemindeki /var/http/dizin/dosya.html dosyası
      sunulacaktır. Hedef dizindeki dosyaları birer CGI betiği olarak imlemesi dışında ScriptAlias yönergesi de aynı şekilde
      çalışır.
    

    
    Biraz daha fazla esnekliğin gerektiği durumlarda  düzenli ifadelere dayalı eşleşmeler sağlamak
      üzere AliasMatch ve ScriptAliasMatch yönergelerinin gücünden
      yararlanılabilir. Örneğin,
    

    
    ScriptAliasMatch "^/~([a-zA-Z0-9]+)/cgi-bin/(.+)" "/home/$1/cgi-bin/$2"
    


    
    satırı sayesinde http://example.com/~user/cgi-bin/betik.cgi
      URL’si /home/user/cgi-bin/betik.cgi dosyası ile
      eşleştirilir ve dosya bir CGI betiği olarak çalıştırılırdı.
    

    top
    

    

    Kullanıcı Dizinleri
    

    
    Geleneksel olarak Unix sistemlerinde belli bir kullanıcının (örn,
      birisi) ev dizinine ~birisi/ şeklinde atıfta
      bulunulabilir. mod_userdir modülü bu özelliği site
      üzerinden kullanıcıların ev dizinlerindeki dosyaları kişisel sayfalar
      olarak sunmalarını sağlamak üzere kullanır. Örnek:
    

    
    http://example.com/~birisi/dosya.html
    

    
    Güvenlik sebebiyle kullanıcıların ev dizinlerine doğrudan HTTP erişimi
      vermek uygun olmaz. Bu bakımdan, kullanıcının ev dizini altında HTTP
      erişimi verilecek dosyaların bulunduğu dizini belirtmek için UserDir yönergesi sağlanmıştır.
      Öntanımlı olan Userdir public_html yapılandırması ile
      yukarıdaki gibi bir URL kullanıcının ev dizini (/etc/passwd
      dosyasında belirtilir) /home/birisi/ altında yer alan
      /home/birisi/public_html/dosya.html dosyası ile
      eşleşirdi.
    

    
    Ev dizininin yerinin /etc/passwd dosyasında belirtilmediği
      sistemlerde kullanılmak üzere Userdir yönergesinin başka
      kullanım şekilleri de vardır.
    

    
    Bazı kişiler (genellikle URL üzerinde %7e olarak
      kodlanması sebebiyle) "~" simgesini biçimsiz bulabilir ve kullanıcı
      dizinlerini imlemek için başka bir karakter kullanmayı tercih
      edebilirler. Bu işlevsellik mod_userdir tarafından
      desteklenmemektedir. Ancak, kullanıcı dizinleri düzgün şekilde
      yapılandırılmışsa istenen etki AliasMatch yönergesi ile sağlanabilir.
      Örneğin, http://example.com/sayfalar/birisi/dosya.html
      URL’si ile /home/birisi/public_html/dosya.html dosyasını
      eşlemek için AliasMatch yönergesi şöyle
      kullanılabilirdi:
    

    
    AliasMatch "^/sayfalar/([a-zA-Z0-9]+)(/(.*))?$" "/home/$1/public_html/$3"
    


    top
    

    

    URL Yönlendirme
    

    
    Yukarıdaki bölümlerde açıklanan yapılandırma yönergeleri httpd’ye
      içeriği dosya sisteminin belli bir yerinden alıp istemciye göndermesini
      söyler. Bazen istemciye, istediği içeriğe farklı bir URL ile
      erişebileceğini ve bu URL için ayrı bir istek yapması gerektiğini
      bildirmek gerekir. Bu işleme yönlendirme adı verilir ve bu
      işlevsellik Redirect yönergesi
      ile sağlanır. Örneğin, DocumentRoot
      altındaki /foo/ dizininin içeriğinin /bar/
      adında yeni bir dizine taşınması halinde istemciye yeni konumun
      bildirilmesi şöyle sağlanabilirdi:
    

    
    Redirect permanent "/foo/" "http://example.com/bar/"
    


    
    Bu atama sayesinde /foo/ ile başlayan URL yolları
      example.com sunucundaki /bar/ dizini altındaki
      içeriğe yönlendirilmektedir. Yönlendirmeyi aynı sunucu üzerinde yapmak
      zorunda değilsiniz, bu yönerge ile başka bir sunucuya da yönlendirme
      yapabilirsiniz.
    

    
    httpd ayrıca, yeniden yazma ile ilgili daha karmaşık sorunlara çözüm
      olarak RedirectMatch diye bir
      yönerge daha sağlar. Örneğin bir sitenin baş sayfasını diğer isteklerden
      ayrı olarak farklı bir siteye yönlendirmek için yönergeyi şöyle
      kullanabilirsiniz:
    

    
    RedirectMatch permanent "^/$" "http://example.com/ilksayfa.html"
    


    
    Bundan başka, bir sitedeki tüm sayfalara yapılan istekleri başka bir
      siteye geçici olarak yönlendirmek için şöyle bir şey yapabilirsiniz:
    

    
    RedirectMatch temp ".*" "http://mesela.example.com/ilksayfa.html"
    


    top
    

    

    Karşı Vekil
    

    
    httpd ayrıca, uzak sunuculardaki belgelerin yerel sunucunun URL
      alanına getirilmesini de mümkün kılar. Bu tekniğe HTTP sunucunun
      belgeleri uzak bir sunucudan alıp istemciye sunmasını sağlayarak bir
      vekil sunucu gibi davranması nedeniyle ters vekalet adı
      verilir. Belgelerin istemciye özkaynağın bulunduğu sunucudan
      geliyormuş gibi değilde doğrudan isteği yaptığı sunucudan geliyormuş
      gibi sunulması nedeniyle bu işlem normal vekaletten farklıdır.
    

    
    Aşağıdaki örnekte, istemci /foo/ dizini altından bir belge
      istemekte, sunucu ise bu belgeyi dahili.example.com
      üzerindeki /bar/ dizininden alıp istemciye yerel sunucudan
      geliyormuş gibi sunmaktadır:
    

    
    ProxyPass "/foo/" "http://dahili.example.com/bar/"
ProxyPassReverse "/foo/" "http://dahili.example.com/bar/"
ProxyPassReverseCookieDomain dahili.example.com harici.example.com
ProxyPassReverseCookiePath "/foo/" "/bar/"
    


    
    ProxyPass sunucuyu uygun
      belgeleri alması için yapılandırırken ProxyPassReverse yönergesi dahili.example.com
      sunucusundan kaynaklanan yönlendirmeleri yeniden yazar, böylece bunların
      yerel sunucudaki yerleri belirlenmiş olur. Benzer şekilde,  ProxyPassReverseCookieDomain ve
      ProxyPassReverseCookiePath
      yönergeleri de arka sunucu tarafından atanan çerezleri yeniden yazar.
    

    
    Yalnız, belgelerin içindeki hiperbağların yeniden yazılmayacağına
      dikkat ediniz. Dolayısıyla, belge içinde
      dahili.example.com’u ismiyle hedef alan mutlak hiperbağlar
      varsa bunlar istemci tarafından vekil sunucudan değil doğrudan
      dahili.example.com’dan istenecektir. Bir sayfanın içindeki bu
      bağları (ve diğer içeriği) mod_substitute modülü
      kullanılarak istemciye sunuluyormuşçasına değiştirebilirsiniz.
    

    
    Substitute "s/dahili\.example\.com/harici.example.com/i"
    


     
    HTML ve XHTML’de hiperbağları daha bilgece yeniden yazabilen
      mod_proxy_html modülü de kullanılabilir. Yeniden
      yazılması gereken URL eşlemlerini oluşturmanızı sağlar, böylece karmaşık
      vekil senaryoları oluşturulabilir.
    

    top
    

    

    Yeniden Yazma Motoru
    

    
    Daha güçlü ikameler gerektiğinde mod_rewrite modülü
      tarafından sağlanan yeniden yazma motoru işe yarayabilir. Bu modüldeki
      yönergeler sunulacak içeriğin yerine karar vermek için kaynak IP adresi,
      tarayıcı türü gibi isteğe özgü özellikleri kullanırlar.
      mod_rewrite modülü buna ek olarak isteğin nasıl ele
      alınacağına karar vermek için harici yazılımları ve veritabanlarını
      kullanabilir. Yeniden yazma motoru yukarıda değinilen üç eşleşme türünü
      de uygulayabilecek yetenektedir: Dahili yönlendirmeler (rumuzlar),
      harici yönlendirmeler ve vekalet. mod_rewrite modülü
      tarafından sağlanan yeteneklerin ayrıntılı açıklamaları ve bunların
      kullanım örnekleri ayrıntılı olarak mod_rewrite
      belgelerinde bulunmaktadır.
    

    top
    

    

    Dosya orada yok
    

    
    Kaçınılmaz olarak, dosya sisteminde mevcut olmayan dosyalar için de
      istek yapılacaktır. Bunun çeşitli sebepleri olabilir.  Bazı durumlarda
      bu, belgelerin yerlerininin değiştirilmesinin bir sonucu olabilir. Bu
      durumda yapılacak en iyi şey, istemciyi belgeyi yeni yerinden istemesi
      için bilgilendirmek amacıyla  URL yönlendirmesi
      kullanmaktır. Bu şekilde, içeriğin yeri değişse bile eski yer imlerinin
      ve hiperbağların çalışmaya devam edeceklerinden emin olabilirsiniz.
    

    
    "Dosya orada yok" ("File Not Found") hatalarının diğer bir bildik
      sebebi de URL’lerin hiperbağlarda veya doğrudan tarayıcıda kasıtlı ya da
      kasıtsız, yanlış yazılmasıdır. Bu tür sorunlarda yardımcı olması için
      httpd mod_speling (sic) adında bir modülle gelir. Bu
      modül etkin kılındığında htpd, "Dosya orada yok" ("File Not Found")
      hatalarının önünü kesip başka bir yerde benzer isimde bir dosya var mı
      diye bakar. Böyle bir dosya varsa, mod_speling
      istemciye dosyanın doğru yerini bildiren bir HTTP yönlendirmesi yollar.
      Benzer çok sayıda dosya varsa bunlar istemciye bir liste halinde
      sunulur.
    

    
    mod_speling modülünün en yararlı özelliklerinden biri
      de dosya isimlerini harf büyüklüğüne duyarsız olarak arayabilmesidir.
      Dosya isimlerinde harf büyüklüğünün önemli olduğu Unix benzeri sistemler
      hakkında bilgisi olmayan kullanıcılara sahip sistemlerin kullanıcılarına
      bu büyük yarar sağlar. Fakat modülün URL düzeltmekten başka şeyler için
      de kullanılması, istemcilerden gelen neredeyse her isteğin URL
      yönlendirmesine konu olmasına sebep olarak sunucunun yükünü
      arttırabilir.
    

    
    mod_dir modülü sanal URI'leri, onları sunan gerçek
      kaynağa eşlemekte kullanılan FallbackResource yönergesini içerir. Bir 'ön denetleyici'
      gerçeklerken mod_rewrite modülünün kullanılmasını
      sağlamak için çok kullanışlıdır.
    

    
    Yerinde bulunmayan içeriğin bulunması çabalarının tümü Apache’nin 404
      (Dosya orada yok) HTTP durum kodlu bir hata sayfası döndürmesine yol
      açar. Bu sayfanın içeriği ErrorDocument yönergesi ile denetlenebilir ve Hata Yanıtlarının Kişiselleştirilmesi
      bölümünde anlatıldığı gibi oldukça esnek bir şekilde
      kişiselleştirilebilir.

    This document explains how the Apache HTTP Server uses the URL of a request
    to determine the filesystem location from which to serve a
    file.

    DocumentRoot
    

    
    In deciding what file to serve for a given request, httpd's
    default behavior is to take the URL-Path for the request (the part
    of the URL following the hostname and port) and add it to the end
    of the DocumentRoot specified
    in your configuration files. Therefore, the files and directories
    underneath the DocumentRoot
    make up the basic document tree which will be visible from the
    web.
    

    
    For example, if DocumentRoot
    were set to /var/www/html then a request for
    http://www.example.com/fish/guppies.html would result
    in the file /var/www/html/fish/guppies.html being
    served to the requesting client.
    

    
    If a directory is requested (i.e. a path ending with
    /), the file served from that directory is defined by
    the DirectoryIndex directive.
    For example, if DocumentRoot were set as above, and 
    you were to set:
    

    
    DirectoryIndex index.html index.php
    

    
    Then a request for http://www.example.com/fish/ will
    cause httpd to attempt to serve the file
    /var/www/html/fish/index.html. In the event that
    that file does not exist, it will next attempt to serve the file
    /var/www/html/fish/index.php.
    

    
    If neither of these files existed, the next step is to
    attempt to provide a directory index, if
    mod_autoindex is loaded and configured to permit
    that.
    

    
    httpd is also capable of Virtual
    Hosting, where the server receives requests for more than one
    host. In this case, a different DocumentRoot can be specified for each
    virtual host, or alternatively, the directives provided by the
    module mod_vhost_alias can
    be used to dynamically determine the appropriate place from which
    to serve content based on the requested IP address or
    hostname.
    

    
    The DocumentRoot directive
    is set in your main server configuration file
    (httpd.conf) and, possibly, once per additional Virtual Host you create.
    

    top
    

    

    Files Outside the DocumentRoot
    

    
    There are frequently circumstances where it is necessary to
    allow web access to parts of the filesystem that are not strictly
    underneath the DocumentRoot. httpd offers several
    different ways to accomplish this. On Unix systems, symbolic links
    can bring other parts of the filesystem under the DocumentRoot. For security reasons,
    httpd will follow symbolic links only if the Options setting for the relevant
    directory includes FollowSymLinks or
    SymLinksIfOwnerMatch.
    

    
    Alternatively, the Alias directive will map any part
    of the filesystem into the web space. For example, with
    


    Alias "/docs" "/var/web"
    


    
    the URL http://www.example.com/docs/dir/file.html
    will be served from /var/web/dir/file.html. The
    ScriptAlias directive
    works the same way, with the additional effect that all content
    located at the target path is treated as CGI scripts.
    

    
    For situations where you require additional flexibility, you
    can use the AliasMatch
    and ScriptAliasMatch
    directives to do powerful regular
    expression based matching and substitution. For
    example,
    

    
    ScriptAliasMatch "^/~([a-zA-Z0-9]+)/cgi-bin/(.+)"   "/home/$1/cgi-bin/$2"
    


    
    will map a request to
    http://example.com/~user/cgi-bin/script.cgi to the
    path /home/user/cgi-bin/script.cgi and will treat
    the resulting file as a CGI script.
    

    top
    

    

    User Directories
    

    
    Traditionally on Unix systems, the home directory of a
    particular user can be referred to as
    ~user/. The module mod_userdir
    extends this idea to the web by allowing files under each user's
    home directory to be accessed using URLs such as the
    following.
    


    http://www.example.com/~user/file.html
    

    
    For security reasons, it is inappropriate to give direct
    access to a user's home directory from the web. Therefore, the
    UserDir directive
    specifies a directory underneath the user's home directory
    where web files are located. Using the default setting of
    Userdir public_html, the above URL maps to a file
    at a directory like
    /home/user/public_html/file.html where
    /home/user/ is the user's home directory as
    specified in /etc/passwd.
    

    
    There are also several other forms of the
    Userdir directive which you can use on systems
    where /etc/passwd does not contain the location of
    the home directory.
    

    
    Some people find the "~" symbol (which is often encoded on the
    web as %7e) to be awkward and prefer to use an
    alternate string to represent user directories. This functionality
    is not supported by mod_userdir. However, if users' home
    directories are structured in a regular way, then it is possible
    to use the AliasMatch
    directive to achieve the desired effect. For example, to make
    http://www.example.com/upages/user/file.html map to
    /home/user/public_html/file.html, use the following
    AliasMatch directive:
    

    
    AliasMatch "^/upages/([a-zA-Z0-9]+)(/(.*))?$"   "/home/$1/public_html/$3"
    


    top
    

    

    URL Redirection
    

    
    The configuration directives discussed in the above sections
    tell httpd to get content from a specific place in the filesystem
    and return it to the client. Sometimes, it is desirable instead to
    inform the client that the requested content is located at a
    different URL, and instruct the client to make a new request with
    the new URL. This is called redirection and is
    implemented by the Redirect directive. For example, if
    the contents of the directory /foo/ under the
    DocumentRoot are moved
    to the new directory /bar/, you can instruct clients
    to request the content at the new location as follows:
    

    
    Redirect permanent "/foo/"   "http://www.example.com/bar/"
    


    
    This will redirect any URL-Path starting in
    /foo/ to the same URL path on the
    www.example.com server with /bar/
    substituted for /foo/. You can redirect clients to
    any server, not only the origin server.
    

    
    httpd also provides a RedirectMatch directive for more
    complicated rewriting problems. For example, to redirect requests
    for the site home page to a different site, but leave all other
    requests alone, use the following configuration:
    

    
    RedirectMatch permanent "^/$"    "http://www.example.com/startpage.html"
    


    
    Alternatively, to temporarily redirect all pages on one site
    to a particular page on another site, use the following:
    

    
    RedirectMatch temp ".*"  "http://othersite.example.com/startpage.html"
    


    top
    

    

    Reverse Proxy
    


    httpd also allows you to bring remote documents into the URL space
of the local server.  This technique is called reverse
proxying because the web server acts like a proxy server by
fetching the documents from a remote server and returning them to the
client.  It is different from normal (forward) proxying because, to the client,
it appears the documents originate at the reverse proxy server.
    


    In the following example, when clients request documents under the
/foo/ directory, the server fetches those documents from
the /bar/ directory on internal.example.com
and returns them to the client as if they were from the local
server.
    


    ProxyPass "/foo/" "http://internal.example.com/bar/"
ProxyPassReverse "/foo/" "http://internal.example.com/bar/"
ProxyPassReverseCookieDomain internal.example.com public.example.com
ProxyPassReverseCookiePath "/foo/" "/bar/"
    



    The ProxyPass configures
the server to fetch the appropriate documents, while the
ProxyPassReverse
directive rewrites redirects originating at
internal.example.com so that they target the appropriate
directory on the local server.  Similarly, the
ProxyPassReverseCookieDomain
and ProxyPassReverseCookiePath
rewrite cookies set by the backend server.
    

    It is important to note, however, that
links inside the documents will not be rewritten. So any absolute
links on internal.example.com will result in the client
breaking out of the proxy server and requesting directly from
internal.example.com. You can modify these links (and other
content) in a page as it is being served to the client using
mod_substitute.
    


    Substitute "s/internal\.example\.com/www.example.com/i"
    



    For more sophisticated rewriting of links in HTML and XHTML, the 
mod_proxy_html module is also available. It allows you
to create maps of URLs that need to be rewritten, so that complex
proxying scenarios can be handled.
    

    top
    

    

    Rewriting Engine
    

    
    When even more powerful substitution is required, the rewriting
    engine provided by mod_rewrite
    can be useful. The directives provided by this module can use
    characteristics of the request such as browser type or source IP
    address in deciding from where to serve content. In addition,
    mod_rewrite can use external database files or programs to
    determine how to handle a request. The rewriting engine is capable
    of performing all three types of mappings discussed above:
    internal redirects (aliases), external redirects, and proxying.
    Many practical examples employing mod_rewrite are discussed in the
    detailed mod_rewrite documentation.

    File Not Found
    

    
    Inevitably, URLs will be requested for which no matching
    file can be found in the filesystem. This can happen for
    several reasons. In some cases, it can be a result of moving
    documents from one location to another. In this case, it is
    best to use URL redirection to inform
    clients of the new location of the resource. In this way, you
    can assure that old bookmarks and links will continue to work,
    even though the resource is at a new location.
    

    
    Another common cause of "File Not Found" errors is
    accidental mistyping of URLs, either directly in the browser,
    or in HTML links. httpd provides the module
    mod_speling (sic) to help with
    this problem. When this module is activated, it will intercept
    "File Not Found" errors and look for a resource with a similar
    filename. If one such file is found, mod_speling will send an
    HTTP redirect to the client informing it of the correct
    location. If several "close" files are found, a list of
    available alternatives will be presented to the client.
    

    
    An especially useful feature of mod_speling, is that it will
    compare filenames without respect to case. This can help
    systems where users are unaware of the case-sensitive nature of
    URLs and the unix filesystem. But using mod_speling for
    anything more than the occasional URL correction can place
    additional load on the server, since each "incorrect" request
    is followed by a URL redirection and a new request from the
    client.
    

    
    mod_dir provides FallbackResource, which can be used to map virtual
    URIs to a real resource, which then serves them. This is a very
    useful replacement for mod_rewrite when implementing
    a 'front controller'
    

    
    If all attempts to locate the content fail, httpd returns
    an error page with HTTP status code 404 (file not found). The
    appearance of this page is controlled with the
    ErrorDocument directive
    and can be customized in a flexible manner as discussed in the
    Custom error responses
    document.

    Other URL Mapping Modules
    



    
    Other modules available for URL mapping include:
    

    
      
    
    • mod_actions - Maps a request to a CGI script
    based on the request method, or resource MIME type.
      • 
    
    • mod_dir - Provides basic mapping of a trailing
    slash into an index file such as index.html.
      • 
    
    • mod_imagemap - Maps a request to a URL based
    on where a user clicks on an image embedded in a HTML document.
      • 
    
    • mod_negotiation - Selects an appropriate
    document based on client preferences such as language or content
    compression.

      Dynamic-Shared-Objects
    
    

    
    exportbeschränkt
    
    
    Verminderte kryptografische Stärke (und Sicherheit), um den
      Exportbesimmungen der Vereinigten Staaten (Anm.d.Ü.: konkret: United
      States' Export Administration Regulations (EAR)) zu
      entsprechen. Exportbeschränkte Verschlüsselungssoftware ist
      auf eine kurze Schlüssellänge begrenzt, was zu
      Chiffretexten führt, die gewöhnlich mittels
      Brute-Force dekodiert werden können.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Filter
    
    
    Ein Verfahren, dass auf vom Server empfangene oder zu sendende Daten
      angewendet wird. Eingabefilter verarbeiten vom Client an den Server
      gesendetet Daten, während Ausgabefilter vom Server an den Client zu
      sendende Daten verarbeiten. Der Ausgabefilter INCLUDES
      beispielsweise untersucht Dokumente nach Server-Side-Includes und führt sie aus.
    
      Siehe: Filter
    
    

    
    Handler
      [ˈhændlə]
    
    
    Eine Apache-interne Darstellung der Aktion, die beim Aufruf einer
      Datei auszuführen ist. Im Allgemeinen besitzen Dateien implizite,
      auf dem Dateityp basierende Handler. Gewöhnlich werden alle Dateien
      vom Server bedient, einige Dateitypen werden jedoch separat "behandelt"
      (Anm.d.Ü.: besitzen einen separaten Handler). Der
      cgi-script-Handler beispielsweise kennzeichnet Dateien, die
      als CGI-Programme ausgeführt werden
      sollen.
    
      Siehe: Verwendung von Apache-Handlern
    
    

    
    Hash
      [hæʃ]
    
    
    Ein mathematischer, unumkehrbarer Einweg-Algorithmus zur Generierung
      einer Zeichenfolge fester Länge aus einer anderen Zeichenfolge
      beliebiger Länge. Unterschiedliche Zeichenfolgen bei der Eingabe
      ergeben üblischerweise unterschiedliche Hashes (abhängig von
      der Hash-Funktion).
    
    

    
    Header
      [hedə]
    
    
    Der Teil der HTTP-Anfrage und -Antwort,

    .htaccess
    
    
    Eine Konfigurationsdatei,
      die innerhalb des Web-Verzeichnisbaums abgelegt wird und zu dem
      Verzeichnis, in dem sie abgelegt ist, sowie allen Unterverzeichnissen
      Konfigurationsdirektiven
      enthält. Trotz ihres Namens kann diese Datei nahezu alle Arten von
      Direktiven enthalten, nicht nur Direktiven zur Zugriffskontrolle.
    
      Siehe: Konfigurationsdateien
    
    

    
    httpd.conf
    
    
    Die Haupt-Konfigurationsdatei ist
      /usr/local/apache2/conf/httpd.conf. Dies kann aber zur
      Laufzeit oder zur Kompilierungszeit anders konfiguriert werden.
    
      Siehe: Konfigurationsdateien
    
    

    
    HTTPS

      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Methode
    
    
    Im HTTP-Kontext eine in der
      Anfrage(zeile) des Clients angegeben Aktion, die auf eine Ressource
      angewendet wird. GET, POST und PUT
      sind einige der verfügbaren HTTP-Methoden.
    
    

    
    MIME-Typ
      [maim tyːp]
    
    
    Eine Art und Weise, den Typ des übermittelten Dokuments zu
      beschreiben. Sein Name leitet sich davon ab, dass sein Format den
      Multipurpose Internet Mail Extensions entlehnt wurde. Er besteht aus
      einem Haupttyp und einem Untertyp, getrennt durch einen 
      Schrägstrich. Einige Beispiele sind text/html,
      image/gif und application/octet-stream.
      Bei HTTP wird der MIME-Typ mit dem Header Content-Type
      übermittelt.
    
      Siehe: mod_mime
    
    

    
    Modul
    
    
    Ein selbstständiger Teil eines Programms. Ein Großteil der
      Funktionalität des Apache ist in Modulen enthalten, die Sie einbinden
      oder entfernen können. In die Apache-Binärdatei httpd einkompilierte Module werden statische Module
      genannt, während Module, die separat gespeichert sind und optional
      zur Laufzeit geladen werden können, dynamische Module oder
      DSOs genannt werden.
      Standardmäßig eingebundene Module werden Basismodule
      genannt. Für den Apache sind viele Module verfügbar, die nicht
      als Bestandteil des Apache-HTTP-Server-Tarballs ausgeliefert
      werden. Diese werden als Drittmodule bezeichnet.
    
      Siehe: Modulverzeichnis
    
    

    
    Module-Magic-Number
      [ˈmɔjuːl mædʒik
      ˈnʌmbə]
      (MMN)
    
    
    Die Module-Magic-Number ist eine Konstante, die im Apache-Quelltext
      definiert ist und im Zusammenhang mit der Binärkompatibilität
      von Modulen steht. Sie wird geändert, wenn sich interne
      Apache-Strukturen, -Funktionen oder andere signifikante Teile der API
      derart ändern, dass eine Binärkompatibilität nicht mehr
      gewährleistet werden kann. Bei einer MMN-Änderung müssen
      alle Module von Drittanbietern zumindest neu kompiliert und zuweilen auch
      geringfügig angepaßt werden, um mit der neuen Apache-Version zu
      funktionieren.
    
    

    
    Öffentlicher
      Schlüssel
    
    
    Der öffentlich verfügbare Schlüssel in einem Public-Key-Kryptographie-System,
      mit dem für seinen Eigentümer bestimmte Nachrichten
      verschlüsselt und Signaturen von seinem Eigentümer
      entschlüsselt werden.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    
    
    
    OpenSSL
      [ˈəupənɛsɛsˈɛl]
    
    
    
    Das Open-Source-Toolkit für SSL/TLS
    
      Siehe: http://www.openssl.org/
    
    

    
    Passphrase
      [paːfreiz]
    
    
    Das Wort oder die Phrase, welches private Schlüssel-Dateien
      schützt. Sie verhindert die Entschlüsselung durch nicht
      authorisierte Benutzer. Normalerweise ist dies einfach der geheimen
      (De-)Codierungsschlüssel, der für Chiffren verwendet wird.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Privater Schlüssel
    
    
    Der geheime Schlüssel in einem Public-Key-Kryptographie-System,
      mit dem hereinkommende Nachrichten decodiert und ausgehende signiert
      werden.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Proxy
    
    
    Ein zwischen dem Client und dem ursprünglichen Server
      (Anm.d.Ü.: der Server, den der Client tatsächlich erreichen
      möchte) liegender Server. Er nimmt Anfragen von
      Clients entgegen, übermittelt diese Anfragen dem
      ursprünglichen Server und liefert die Antwort des
      ursprünglichen Servers an den Client zurück. Wenn mehrere
      Clients den gleichen Inhalt abfragen, dann kann der Proxy diesen Inhalt
      aus seinem Zwischenspeicher ausliefern, anstatt ihn jedesmal vom
      ursprünglichen Server anzufordern, und dadurch die Antwortzeit
      verringern.
    
      Siehe: mod_proxy
    
    

    
    Public-Key-Kryptographie
      [ˈpʌblik kiː
      ˈkyptograˈfiː]
    
    
    Theorie und Anwendung asymmetrischer Verschlüsselungssysteme,
      die einen Schlüssel zur Verschlüsselung und einen anderen zur
      Entschlüsselung verwenden. Zwei derart zusammengehörende
      Schlüssel bilden Schüsselpaar. Man spricht auch von
      "Asymetrischer Kryptographie".
    
      Siehe: SSL/TLS-Verschlüsselung
    
    
    
    
    Regulärer
      Ausdruck (Regex)
    
    
    Eine Form, ein Muster im Text zu beschreiben - zum Beispiel: "alle
      Wörter, die mit dem Buchstaben A beginnen" oder "Jeder Satz mit
      zwei Kommata und ohne großes Q". Beim Apache sind reguläre
      Ausdrücke hilfreich, da sie auf sehr flexible Art und Weise die
      Anwendung bestimmter Eigenschaften auf eine Auswahl von Dateien oder
      Ressourcen ermöglichen. - Zum Beispiel können alle .gif- und
      .jpg-Dateien eines Verzeichnis "images" mit
      "/images/.*(jpg|gif)$" beschrieben werden. Der Apache
      verwendet Perl-kompatible reguläre Ausdrücke, wie sie die
      PCRE-Bibliothek bereitstellt.
    
    

    
    Reverse Proxy
      [riːvəːs
      ˈprɔksi]
    
    
    Ein Proxy-Server, der dem Client
      gegenüber als ursprünglicher Server erscheint. Dies
      ist nützlich, um den tatsächlichen Server aus
      Sicherheitsgründen oder zur Lastverteilung vor dem Client zu
      verstecken.

      Entschlüsselung benutzen.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Tarball
      [taːbɔːl]
    
    
    Ein Paket von Dateien, die mit dem Hilfsprogramm tar
      zusammengefasst wurden. Apache-Distributionen werden in komprimierten

      riˈsɔːs ləuˈkeitə]
      (URL)
    
    
    Der Name bzw. die Adresse einer Ressource im Internet. Dies ist der
      allgemein gebräuchliche Audruck für die formale Bezeichnung
      Uniform Resource
      Identifier. URLs bestehen üblicherweise aus einem
      Schema wie http oder https, einem Hostnamen
      und einem Pfad. Die URL für diese Seite ist
      http://httpd.apache.org/docs/2.4/glossary.html.

      [ˈjuːnifɔːm
      riˈsɔːs aiˈdentifaiə] 
      (URI)
    
    
    Eine kompakte Zeichenfolge zur Identifizierung einer abstrakten oder
      physischen Ressource. Er wird in dem RFC 2396 formell
      definiert. Im World Wide Web verwendete URIs werden üblicherweise
      als URLs bezeichnet.
    
    

    
    Virtual-Hosting
      [vəˈtjuəl
      həustiŋ]
    
    
    Die Bedienung mehrere Websites mit einer einzigen Apache-Instanz.
      IP-basierte virtuelle Hosts unterscheiden zwischen
      verschiedenen Websites aufgrund ihrer IP-Adressen, während
      namensbasierte virtuelle Hosts nur den Namen des Hosts
      verwenden und daher mehrere Angebote unter der gleichen IP-Adresse
      hosten können.
    
      Siehe: Apache-Dokumentation zu virtuellen
      Hosts

      (FQDN)
    
    
    Der eindeutige Name einer Netzwerkeinheit, bestehend aus einem
      Hostnamen und dem Domainnamen, welcher zu einer IP-Adresse
      aufgelöst werden kann. Zum Beispiel ist www ein
      Hostname, example.com ein Domainname und
      www.example.com ein voll-qualifizierter Domainname.
    
    

    
    
    Website
      [websait]
    
    
    Im Gegensatz zur Webseite, die einer konkreten URL entspricht, ist mit
      Website ein komplettes Angebot unter einem bestimmten Hostnamen (und Port)
      gemeint. Dieses kann aus vielen verschiedenen Webseiten bestehen.
    
    

    
    X.509
    
    
    Ein von der International Telecommunication Union (ITU-T) empfohlenes
      Schema für Authentifizierungszertifikate. Es wird für
      SSL/TLS-Authentifizierungen verwendet.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Zertifikat
    
    
    Ein Datensatz zur Authentisierung einer 
      Nertzwerkeinheit wie Server oder Client. Ein Zertifikat
      enthält X.509-Informationen
      über seinen Eigentümer (das sogenannte Betreff
      (Anm.d.Ü.: engl.: subject)) und die
      signierende Certification
      Authority (der sogenannte Aussteller (Anm.d.Ü.: engl.:
      issuer)) sowie den öffentlichen Schlüssel des
      Eigentümers und die Signatur der CA. Netzwerkeinheiten
      überprüfen diese Signatur mit Hilfe von CA-Zertifikaten.
    
      Siehe: SSL/TLS-Verschlüsselung
    
    

    
    Zugriffskontrolle
    
    
    Die Beschränkung des Zugriffs auf Netzwerkbereiche. Im
      Apache-Kontext in der Regel die Zugriffsbeschränkung auf bestimmte
      URLs.

    On Windows, Apache is normally run as a service.
    For details, see Running Apache as a Service.
    
    

    
    On Unix, the httpd program
    is run as a daemon that executes continuously in the
    background to handle requests.  This document describes how
    to invoke httpd.
    

    


    top
    

    

    How Apache Starts
    

    
    If the Listen
    specified in the configuration file is default of 80 (or any other
    port below 1024), then it is necessary to have root privileges in
    order to start apache, so that it can bind to this privileged
    port. Once the server has started and performed a few preliminary
    activities such as opening its log files, it will launch several
    child processes which do the work of listening for and
    answering requests from clients. The main httpd
    process continues to run as the root user, but the child processes
    run as a less privileged user. This is controlled by the selected
    Multi-Processing Module.
    

    
    The recommended method of invoking the httpd
    executable is to use the apachectl control script. This
    script sets certain environment variables that are necessary for
    httpd to function correctly under some operating
    systems, and then invokes the httpd binary.
    apachectl will pass through any command line
    arguments, so any httpd options may also be used with
    apachectl.  You may also directly edit the
    apachectl script by changing the HTTPD
    variable near the top to specify the correct location of the
    httpd binary and any command-line arguments that you
    wish to be always present.
    

    
    The first thing that httpd does when it is
    invoked is to locate and read the configuration file
    httpd.conf. The location of this file is set at
    compile-time, but it is possible to specify its location at run
    time using the -f command-line option as in
    


    /usr/local/apache2/bin/apachectl -f
      /usr/local/apache2/conf/httpd.conf
    

    
    If all goes well during startup, the server will detach from
    the terminal and the command prompt will return almost
    immediately. This indicates that the server is up and running.
    You can then use your browser to connect to the server and view
    the test page in the DocumentRoot directory.
    

    top
    

    

    Errors During Start-up
    

    
    If Apache suffers a fatal problem during startup, it will
    write a message describing the problem either to the console or
    to the ErrorLog before
    exiting. One of the most common error messages is "Unable
    to bind to Port ...". This message is usually caused by
    either:
    

    
      
      
    • Trying to start the server on a privileged port when not
      logged in as the root user; or
      • 

      
    • Trying to start the server when there is another instance
      of Apache or some other web server already bound to the same
      Port.
      • 
    
    

    
    For further trouble-shooting instructions, consult the
    Apache FAQ.
    

    top
    

    

    Starting at Boot-Time
    

    
    If you want your server to continue running after a system
    reboot, you should add a call to apachectl to your
    system startup files (typically rc.local or a file in
    an rc.N directory). This will start Apache as
    root. Before doing this ensure that your server is properly
    configured for security and access restrictions.
    

    
    The apachectl script is designed to act like a
    standard SysV init script; it can take the arguments
    start, restart, and stop
    and translate them into the appropriate signals to
    httpd.  So you can often simply link
    apachectl into the appropriate init directory. But be
    sure to check the exact requirements of your system.
    

    top
    

    

    Additional Information
    

    
    Additional information about the command-line options of httpd and apachectl as well as other support
    programs included with the server is available on the
    Server and Supporting Programs page.
    There is also documentation on all the modules included with the Apache distribution
    and the directives that they
    provide.

    Apache HTTP Sunucusu 4xx veya 5xx HTTP durum kodları ile ilgili
      olaylarda soysal hata yanıtları üretse de bu yanıtlar site
      kullanıcılarına aşırı sade, bilgi vermez ve hatta korkutucu gelebilir.
      Daha dostça yazılmış, İngilizce değil de kendi dilinizde ve belki
      sayfalarınızın yerleşimine uygun daha hoş satırlarda özel hata yanıtları
      üretmek isteyebilirsiniz.
    

    
    Kişiselleştirilmiş hata yanıtları, bir hata durumuna göre tasarlanmış
      herhangi bir HTTP durum kodu (yani 4xx ve 5xx kodlarından biri) için
      tanımlanabilir.
    

    
    Ek olarak bir değer kümesi de sağlanmıştır. Böylece hata belgeleri, Sunucu taraflı İçerik Yerleştirme kullanılarak
      bu değişkenlerin değerlerine göre özelleştirilebilir. İsterseniz bunun
      yerine bir CGI programı veya devingen bir eylemci (PHP, mod_perl, vs.)
      kullanarak da bu değişkenlerin değerlerine göre hata sayfalarınızı
      üretebilirsiniz.
    

  
    


    top
    

    

    Yapılandırma
    

    
    Kişiselleştirilmiş hata belgeleri ErrorDocument yönergesi kullanılarak yapılandırılabilir. Bu
      yönerge küresel bağlamda olabileceği gibi sanal konak ve dizin
      bağlamlarında da kullanılabilir. AllowOverride yönergesine FileInfo
      atanarak .htaccess dosyalarında da kullanılabilir.
    

    
    ErrorDocument 500 "Pardon, galiba bizim betik hata verdi."
ErrorDocument 500 /cgi-bin/hata-kurtarma
ErrorDocument 500 http://error.example.com/server_error.html
ErrorDocument 404 /ozuru_kabahatinden_buyuk/yok.html
ErrorDocument 401 /Uyeler/NASIL_uye_olunur.html
    


    
    ErrorDocument yönergesinin sözdizimi:
    

    
    ErrorDocument <3-rakamlı-kod> <eylem>
    


    
    eylem şunlardan biri olabilir:
    

    
      
      
    1. Yönlendirmenin yapılacağı dahili adres (eylem bir "/" ile
        başlıyorsa).
      2. 
      
    2. Yönlendirmenin yapılacağı harici adres (eylem geçerli bir
        URL ise).
      3. 
      
    3. Gösterilecek metin (yukardakilerin hiçbiri yoksa). Birden fazla
        sözcük içeriyorsa tırnak (") içine alınmalıdır.
      4. 
    
    

    
    Yerel bir adrese yönlendirme yapılırken ek ortam değişkenleri de
      atanarak yanıt daha da özelleştirilebilir. Bunlar harici URL'lere
      gönderilmez.
    

  
    top
    

    

    Kullanılabilen Değişkenler
    

      
    Hata durumunu açıklayacak veya hata günlüğüne daha açıkça
        kaydedilebilecek bazı bilgilerin aktarılması koşuluyla, başka bir
        adrese yönlendirme kullanışlı olabilir
    

      
    Hata yönlendirmesi yapılırken bunu sağlamak için ek ortam değişkenleri
        tanımlanır. Bu değişkenlerin isimleri, özgün istekle sağlanan
        başlık isimlerinin  önüne 'REDIRECT_' dizgesi getirilerek üretilir.
        Böylece özgün istek bağlamından hata belgesi üretilebilir.
    

      
    Örneğin, aşağıdaki gibi, daha yararlı olacak ek ortam değişkenleri
        alabilirsiniz.
    

      
    
        REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/jpeg, image/png
    
        REDIRECT_HTTP_USER_AGENT=Mozilla/5.0 Fedora/3.5.8-1.fc12 Firefox/3.5.8
    
        REDIRECT_PATH=.:/bin:/usr/local/bin:/sbin
    
        REDIRECT_QUERY_STRING=
    
        REDIRECT_REMOTE_ADDR=121.345.78.123
    
        REDIRECT_REMOTE_HOST=client.example.com
    
        REDIRECT_SERVER_NAME=www.example.edu
    
        REDIRECT_SERVER_PORT=80
    
        REDIRECT_SERVER_SOFTWARE=Apache/2.2.15
    
        REDIRECT_URL=/cgi-bin/buggy.pl
      
    

      
    REDIRECT_ ortam değişkenleri, yönlendirme öncesi varolan
        ortam değişkenlerinden üretilir. Bunlar önlerine REDIRECT_
        getirilerek yeniden isimlendirilir. Örneğin,
        HTTP_USER_AGENT değişkeni
        REDIRECT_HTTP_USER_AGENT haline gelir.
    

      
    REDIRECT_URL, REDIRECT_STATUS ve
        REDIRECT_QUERY_STRING mutlaka atanır. Diğer başlıklarla
        ilgili olanlar ise hata durumu öncesinde mevcut oldukları takdirde
        üretilirler.
    

      
    Eğer ErrorDocument hedefi bir
        harici yönlendirme ise bunların hiçbiri
        üretilmez (sunucunun bulunduğu konağı hedeflese bile http:
        ile başlayan herşey harici yönlendirme sayılır).
    
  
    top
    

    

    Özel Hata Yanıtları
    

      
    Hata yanıtınızı üretmek için sunucu taraflı içerik yerleştirme, bir
        CGI betiği veya başka bir eylemciyi devingen eylemci olarak
        kullanıyorsanız, bu yanıtı özelleştirmek için bu kullanıma özel
        üretilmiş ortam değişkenlerini kullanmak isteyebilirsiniz.
    

      
    ErrorDocument yönergesi bir CGI
        betiğine bir yerel yönlendirme belirtiyorsa, hatanın kaynağı hakkında
        istemciye bilgi vermek amacıyla betiğin çıktısında bir
        "Status:" başlık alanına yer verilmelidir. Örneğin, bir
        Perl betiği şunları içerebilirdi:
    

      
    ...
print  "Content-type: text/html\n";
printf "Status: %s durumu saptandı.\n", $ENV{"REDIRECT_STATUS"};
...
    


      
    Eğer betik, 404 Not Found gibi, belli bir hata
        durumunu ele almaya adanmışsa duruma özel kod ve hata metni
        kullanılabilir.
    

      
    Eğer yanıt, (istemci taraflı yönlendirme yapılırken) bir
        Location: başlığı da içeriyorsa betiğin çıktıya uygun bir
        Status: başlığı (302 Found) eklemesinin
        gerekli oluşuna dikkat ediniz. Aksi takdirde, Location:
        başlığı etkisiz olabilir.
    

  
    top
    

    

    Çok Dilli Özel Hata Belgeleri
    

    
    Apache HTTP Sunucusunun kurulumunda, 16 dile çevrilmiş özel hata
      iletileri belgeleri içeren bir dizin bulunmaktadır. Ayrıca,
      conf/extra yaplandırma dizininde bu özelliği etkin kılmak
      için yapılandırmaya dahil edilebilecek bir yapılandırma dosyası
      vardır.
    

    
    Sunucu yapılandırma dosyanızda şöyle satırlar görebilirsiniz:
    

    
    # Multi-language error messages
#Include conf/extra/httpd-multilang-errordoc.conf
    


    
    Bu Include satırını açıklama olmaktan çıkarırsanız
      bu özelliği etkinleştirmiş olursunuz. Böylece, istemcinin tarayıcısında
      belirtilmiş dil tercihine uygun dil uzlaşımlı hata iletileri
      sağlanır.
    

    
    Ek olarak, bu belgeler çeşitli REDIRECT_ değişkenleri
      içerir. Böylece, son kullanıcıya neler olduğu ve şimdi ne yapması
      beklendiği hakkında ek bilgiler sağlanabilir.
    

    
    Bu belgeleri istediğiniz kadar özelleştirebilir, kullanıcıya siteniz
      hakkında ve orada bulabilecekleri şeylere dair faydalı bilgiler de
      sağlayabilirsiniz.
    

    
    Bu özelliği kullanmak için mod_include ve
      mod_negotiation etkin kılınmalıdır.

    フィルタ とは、サーバが送受信したデータに
    適用される処理プロセスのことをいいます。クライアントからサーバに
    送られたデータは 入力フィルタ によって、サーバから
    クライアントに送られるデータは出力フィルタによって
    処理されます。複数のフィルタを適用することができ、
    その順番を厳密に指定することもできます。
    

    
    Apache 内部では、チャンク (データのぶつ切り) を行ったり、

    Çok büyük sayıda sanal konak kullanıyorsanız ve bunların her biri için
      ayrı günlük kayıtları tutuyorsanız, Apache dosya tanıtıcılarını
      tüketebilir. Apache tarafından, dahili olarak 10-20 dosya tanıtıcıya ek
      olarak her hata günlüğü için bir ve her diğer günlük kaydı için bir dosya
      tanıcı kullanılır. Unix işletim sisteminde dosya tanıtıcıların sayısı
      süreç başına 64 taneyle sınırlıdır ve gerekirse donanıma bağlı olarak
      arttırılabilir.
    

    
    Apache gerektiğinde bu sınırı kendisi arttırmaya çalışırsa da bu her
      zaman mümkün olmaz. Şöyle ki:
    

    
      
      
    1. Sisteminiz setrlimit() sistem çağrısını
        sağlamıyordur.
      2. 

      
    2. Sisteminizde setrlimit(RLIMIT_NOFILE) çağrısı hiçbir işe
        yaramıyordur (örneğin, Solaris 2.3).
      3. 

      
    3. Dosya tanıtıcılarının sayısı donanıma bağlı olarak daha fazla
        arttırılamıyordur.
      4. 

      
    4. Sisteminiz dosya tanıtıcı sayısını başka sınırlara bağlı kılmıştır:
        örneğin stdio akımları ile ilgili sınır, dosya tanıtıcı sayısının
        256’nın altında ollmasını gerektiriyordur (Solaris 2).
      5. 
    
    

    
    Böyle sorunlar karşısında yapabilecekleriniz:
    

    
    • Ana günlük dosyaları hariç, <VirtualHost> bölümlerinde günlük dosyası
      belirtmeyerek günlük dosyası sayısını düşürürsünüz. (Bunun nasıl
      yapılacağını öğrenmek için Günlük kayıtlarının
      ayrıştırılması bölümüne bakınız.)
      • 

      
    • Sisteminizde serbest dosya tanıtıcı sayısı 1-2 civarına düşerse
        Apache’yi aşağıdaki gibi bir betikle yeniden çalıştırarak dosya
        tanıtıcı sayısını arttırabilirsiniz:

        
      
          #!/bin/sh
      
           ulimit -S -n 100
      
           exec httpd      
        
      
      
      • 
    
    


    

    top
    

    

    Günlük kayıtlarının ayrıştırılması
    

    
    Günlük dosyalarını çok sayıda sanal konak için ortak olarak
      kullanıyorsanız, sanal konaklar için istatistiksel çözümlemeler yapmak
      amacıyla sırası geldiğinde bunları ayrıştırabilirsiniz. Bu işlem aşağıda
      anlatıldığı gibi yapılabilir.
    

    
    İlk iş olarak, sanal konak bilgilerini günlük girdilerine eklemeniz
      gerekir. Bu işlem, LogFormat yönergesi ve
      %v biçem değişkeni ile yapılabilir. Günlük girdisi biçem
      dizgesinin başına bunu ekleyiniz:
    

    
    LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost
CustomLog logs/multiple_vhost_log vhost
    


    
    Bu yapılandırma ile her günlük kaydının başında sanal konağın
      ServerName yönergesine belirtilen
      ismi eklenir. (Günlük dosyalarınızın kişiselleştirilmesi ile ilgili daha
      fazla bilgi için mod_log_config belgesine bakınız.)
    

    
    Günlük dosyanızdaki kayıtları bileşenlere göre gruplamak isterseniz
      split-logfile
      programını kullanabilirsiniz. Bu programı Apache dağıtımının
      support dizininde bulabilirsiniz.
    

    
    Programı aşağıdaki gibi çalıştırın:
    

    
    
    split-logfile < /logs/multiple_vhost_log
    
    

    
    Bu programı sanal konaklar için tuttuğunuz günlük dosyasının ismini
      argüman olarak belirterek çalıştırdığınızda o dosyadaki kayıtlardan her
      sanal konak için ayrı bir günlük dosyası
      (konakadı.log) üretilir.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    
    この文書では名前ベースのバーチャルホストをどんなとき、
    どうやって使うかを説明します。
    

    


    top
    

    

    名前ベースと IP ベースのバーチャルホストの比較
    

    
    IP ベースのバーチャルホストでは、応答する
    バーチャルホストへのコネクションを決定するために IP
    アドレスを使用します。ですから、それぞれのホストに個々に IP
    アドレスが必要になります。これに対して名前ベースのバーチャルホストでは、
    クライアントが HTTP ヘッダの一部としてホスト名を告げる、
    ということに依存します。この技術で同一 IP 
    アドレスを異なる多数のホストで共有しています。
    

    
    名前ベースのバーチャルホストは通常単純で、それぞれのホスト名と
    それに対応する正確な IP アドレスを DNS で設定し、異なる
    ホスト名を区別するように Apache HTTP サーバを設定するだけです。
    さらに、名前ベースのバーチャルホストは不足する IP
    アドレスの需要を緩和します。したがって、IP ベースのバーチャルホストを
    選択すべき特定の理由がなければ名前ベースのバーチャルホストを使うべきです。
    IP ベースのバーチャルホストを使用することを考慮する理由として、
    

    
       
      
    • 名前ベースのバーチャルホストに対応していない古いクライアントがある
      名前ベースのバーチャルホストが働くためには、クライアントは
      HTTP ホストヘッダを送ってこなければなりません。
      これは HTTP/1.1 の仕様で要求されていて、すべての現代的な
      HTTP/1.0 ブラウザでも拡張として実装されています。
      とても古いクライアントをサポートしつつ、名前ベースの
      バーチャルホストを行いたい場合は、この文書の最後の方に
      書かれている解決策になるかもしれない方法を見てください。
      • 

      
    • 名前ベースのバーチャルホストは SSL プロトコルの特徴により、
      SSL セキュアサーバには使えません。
      • 

      
    • オペレーティングシステムやネットワーク装置のなかには、
      別の IP アドレス上でない場合、複数のホストを別扱いできないような
      帯域管理の方法を実装しているものがあります。

    名前ベースのバーチャルホストを利用する
    


    関連モジュール関連ディレクティブ
    

    
    名前ベースのバーチャルホストを使うには、そのホストへの
    リクエストを受け付けるサーバの IP アドレス (もしかしたらポートも)
    を指定する必要があります。
    これは NameVirtualHost
    ディレクティブで設定します。通常、NameVirtualHost で
    * の属性を使ってサーバの全ての IP アドレスを使います。
    (例えば SSL の使用などで) 複数のポートを使うことを計画しているのであれば、
    引数に *:80 のようにポートも含めるようにしてください。
    NameVirtualHost ディレクティブで
    IP アドレスを書いても、
    自動的にサーバがその IP アドレスをリッスンするということはないことに
    注意してください。詳細は「Apache の使うアドレスと
    ポートを設定する」を読んでください。さらに、ここで指定された
    IP アドレスは全てサーバのネットワークインターフェースと関連付けられて
    いなければなりません。
    

    
    次は、扱うホストそれぞれに対して <VirtualHost> ブロックを
    作成してください。<VirtualHost>
    ディレクティブの引数は NameVirtualHost
    ディレクティブの引数と同じにしてください (すなわち、IP アドレスか、全てのアドレスを意味する
    *)。それぞれの <VirtualHost>
    ディレクティブの中には、最低限、どのホストが扱われるかを示す ServerName ディレクティブと、
    そのホスト用のコンテンツがファイルシステム上のどこにあるかを示す
    DocumentRoot ディレクティブを
    書く必要があります。
    

    
    メインホストはなくなります
    
        
    既にあるウェブサーバにバーチャルホストを追加する場合、
        既存のウェブサーバに対しても <VirtualHost>
        ブロックを作らなければなりません。このバーチャルホストの
        ServerName と
        DocumentRoot
        は、グローバルな ServerName と
        DocumentRoot
        と同じものにします。また、このバーチャルホストを設定ファイルの中で
        先頭に置いて、デフォルトホストとして動作するようにします。
    
    
    

    
    たとえば、www.domain.tld を動かしていて、
    さらにバーチャルホスト www.otherdomain.tld
    を追加するとしましょう。このバーチャルホストは同一 IP を指しているとします。
    そのような場合は、httpd.conf
    に以下のようなコードを追加するだけです
    

    
    
        NameVirtualHost *:80
    
        
    
        <VirtualHost *:80>
    
        
            ServerName www.domain.tld
    
            ServerAlias domain.tld *.domain.tld
    
            DocumentRoot /www/domain
    
            
        </VirtualHost>
    
        
    
        <VirtualHost *:80>
    
        ServerName www.otherdomain.tld
    
            DocumentRoot /www/otherdomain
    
            
        </VirtualHost>
    
    
    

    
    NameVirtualHost 及び
    VirtualHost のどちらの場合も、
    * の部分には明示的に IP アドレスを指定することができます。
    例えば、ある IP アドレスでは名前ベースのバーチャルホストを使いたい一方で、
    別の IP アドレスでは、他の IP ベースのバーチャルホストや
    別組の名前ベースのバーチャルホストを使いたい場合、
    そう設定することになるでしょう。
    

    
    複数の名前でサーバアクセスができるようにしたいことも多いでしょう。
    このようなことは、ServerAlias ディレクティブを <VirtualHost>
    セクションに記述することで実現できます。
    例えば上記の <VirtualHost> の例であれば、
    次のように一覧に挙げられた名前が、
    ユーザが同一のウェブサイトとして目にして使用できるサーバ名である、
    と ServerAlias
    ディレクティブで指定できます。
     

    
    
        ServerAlias domain.tld *.domain.tld
    
    

    
    domain.tld ドメインへの全てのホストへのリクエストは
    www.domain.tld のバーチャルホストが処理します。
    名前をマッチさせるために、ワイルドカード文字 * や ? 
    を使用することもできます。もちろん思いつきの名前を作って、
    ServerName や 
    ServerAlias
    にその名前を書くといったことはできません。まずは、
    これらの名前が サーバに付けられた IP アドレスにマップされるように
    DNS サーバを適切に設定しなければなりません。
    

    
    最後に、<VirtualHost> コンテナの中に
    他のディレクティブを書くことで、バーチャルホストの設定を細かく調整
    することができます。
    ほとんどのディレクティブはこれらのコンテナに設置することができて、
    変更点はそのバーチャルホストに対してのみ有効になります。
    どのディレクティブを書くことができるかは、ディレクティブの コンテキスト を
    調べてください。主サーバコンテキスト
    (<VirtualHost>
    コンテナの外) の設定用ディレクティブはバーチャルホストでの設定で
    上書きされない場合のみ使用されます。
    

    
    リクエストが来ると、サーバはまず最初に <NameVirtualHost>
    にマッチする IP アドレスかどうかをチェックします。マッチすれば
    マッチした IP アドレスの <VirtualHost>
    のそれぞれのセクションの中から 
    ServerName か
    ServerAlias 
    に要求されたホスト名があるか探します。
    見つかればそのサーバ用の設定を使います。マッチするバーチャルホスト
    が見つからなければ、マッチした IP アドレスの 
    リストの最初にあるバーチャルホスト が使われます。
    

    
    結果として、リストの最初のバーチャルホストが デフォルト の
    バーチャルホストになります。IP アドレスが NameVirtualHost
    ディレクティブにマッチした場合は、メインのサーバ の
    DocumentRoot 
    は決して使われません
    どのバーチャルホストにもマッチしないリクエストに対して、
    特別な設定をしたいのであれば、設定ファイル中の最初の
    <VirtualHost> コンテナにそれを記述してください。
    


    top
    

    

    古いブラウザとの互換性
    

    
    以前述べたように、名前ベースのバーチャルホストが正しく動作する
    ために必要な情報を送ってこないクライアントが依然として存在しています。
    そのようなクライアントに対しては、該当する IP アドレスについて、
    一番最初に設定されているバーチャルホスト
    (プライマリの名前ベースのバーチャルホスト)
    からページが送り返されます。
    

    
    どのぐらい古いの ?
    
    
    「古い」と表現している場合、本当に古いことを意味して使っています。
    不幸にして今現在でもこのような古いブラウザに遭遇することがあります。
    現在のブラウザは全て、名前ベースのバーチャルホストに必要な
    Host ヘッダを送ります。
    
    
    

    
    ServerPath
    ディレクティブで対処が可能です。ちょっと不格好ですけれども。
    

    
    設定例
    

    
    
        NameVirtualHost 111.22.33.44
    
        
    
        <VirtualHost 111.22.33.44>
    
        
            ServerName www.domain.tld
    
            ServerPath /domain
    
            DocumentRoot /web/domain
    
            
        </VirtualHost>
    
    
    

    
    この例にはどういう意味があるでしょうか? これは
    "/domain" で始まる URI へのリクエストはすべて、
    バーチャルホスト www.domain.tld で処理される、
    という意味です。つまり、すべてのクライアントで
    http://www.domain.tld/domain/ でアクセスできるページが、
    Host: ヘッダを送ってくるクライアントであれば
    http://www.domain.tld/ としてもアクセスできる、
    という意味です。
    

    
    これが動作するようにするには、
    プライマリのバーチャルホストのページに
    http://www.domain.tld/domain/ へのリンクを設置します。
    そして、バーチャルホストのページでは、純粋な相対リンク (例:
    "file.html" や "../icons/image.gif")、
    あるいは /domain/ で始まるリンク (例:
    "http://www.domain.tld/domain/misc/file.html" や
    "/domain/misc/file.html") だけを設置します。
    

    
    これには、幾分かの規律が必要となりますが、
    このようなガイドラインを忠実に守ることにより、たいていの場合、
    すべてのブラウザで ― 新しいブラウザでも古いものでも ―
    作成したページが見えるということを保証します。

    This document describes how to efficiently serve an
    arbitrary number of virtual hosts with the Apache HTTP Server. A
    separate document discusses using
    mod_rewrite to create dynamic mass virtual hosts.
    
    


    


    top
    

    

    Motivation
    

    
    The techniques described here are of interest if your
    httpd.conf contains many
    <VirtualHost> sections that are
    substantially the same, for example:
    


    <VirtualHost 111.22.33.44>
    ServerName                 customer-1.example.com
    DocumentRoot        "/www/hosts/customer-1.example.com/docs"
    ScriptAlias  "/cgi-bin/"  "/www/hosts/customer-1.example.com/cgi-bin"

<VirtualHost 111.22.33.44>
    ServerName                 customer-2.example.com

</VirtualHost>
    


    
    We wish to replace these multiple
    <VirtualHost> blocks with a mechanism
    that works them out dynamically. This has a number of
    advantages:
    

    
      
      
    1. Your configuration file is smaller, so Apache starts
      more quickly and uses less memory. Perhaps more importantly, the
      smaller configuration is easier to maintain, and leaves less room
      for errors.
      2. 

      
    2. Adding virtual hosts is simply a matter of creating the
      appropriate directories in the filesystem and entries in the
      DNS - you don't need to reconfigure or restart Apache.
      3. 
    
    

    
    The main disadvantage is that you cannot have a different log file for
    each virtual host; however, if you have many virtual hosts, doing
    this can be a bad idea anyway, because of the number of file descriptors needed.
    It is better to log to a pipe or a fifo,
    and arrange for the process at the other end to split up the log
    files into one per virtual host. One example of such a process can
    be found in the split-logfile
    utility.

    Overview
    

    
    A virtual host is defined by two pieces of information: its
    IP address, and the contents of the Host: header
    in the HTTP request. The dynamic mass virtual hosting technique
    used here is based on automatically inserting this information into the
    pathname of the file that is used to satisfy the request. This
    can be most easily done by using mod_vhost_alias
    with Apache httpd. Alternatively,
    mod_rewrite can
    be used.
    
    
    Both of these modules are disabled by default; you must enable
    one of them when configuring and building Apache httpd if you want to
    use this technique.
    

    
    A couple of things need to be determined from the request in
    order to make the dynamic
    virtual host look like a normal one. The most important is the
    server name, which is used by the server to generate
    self-referential URLs etc. It is configured with the
    ServerName directive, and it is available to CGIs
    via the SERVER_NAME environment variable. The
    actual value used at run time is controlled by the UseCanonicalName
    setting. With UseCanonicalName Off, the server name
    is taken from the contents of the Host: header in the
    request. With UseCanonicalName DNS, it is taken from a
    reverse DNS lookup of the virtual host's IP address. The former
    setting is used for name-based dynamic virtual hosting, and the
    latter is used for IP-based hosting. If httpd cannot work out
    the server name because there is no Host: header,
    or the DNS lookup fails, then the value configured with
    ServerName is used instead.
    

    
    The other thing to determine is the document root (configured
    with DocumentRoot and available to CGI scripts via the
    DOCUMENT_ROOT environment variable). In a normal
    configuration, this is used by the core module when
    mapping URIs to filenames, but when the server is configured to
    do dynamic virtual hosting, that job must be taken over by another
    module (either mod_vhost_alias or
    mod_rewrite), which has a different way of doing
    the mapping. Neither of these modules is responsible for
    setting the DOCUMENT_ROOT environment variable so
    if any CGIs or SSI documents make use of it, they will get a
    misleading value.

    Dynamic Virtual Hosts with
mod_vhost_alias
    

    
    This extract from httpd.conf implements the
    virtual host arrangement outlined in the Motivation section above
    using mod_vhost_alias.
    


    # get the server name from the Host: header
UseCanonicalName Off

# this log format can be split per-virtual-host based on the first field
# using the split-logfile utility.
LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# include the server name in the filenames used to satisfy requests
VirtualDocumentRoot "/www/hosts/%0/docs"
VirtualScriptAlias  "/www/hosts/%0/cgi-bin"
    


    
    This configuration can be changed into an IP-based virtual
    hosting solution by just turning UseCanonicalName
    Off into UseCanonicalName DNS. The server
    name that is inserted into the filename is then derived from
    the IP address of the virtual host. The variable %0
    references the requested servername, as indicated in the
    Host: header.
    


    See the mod_vhost_alias documentation for more usage
examples.

    Simplified Dynamic Virtual Hosts
    

    
    This is an adjustment of the above system, tailored for an
    ISP's web hosting server. Using %2,
    we can select substrings of the server name to
    use in the filename so that, for example, the documents for
    www.user.example.com are found in
    /home/user/www. It uses a single cgi-bin
    directory instead of one per virtual host.
    


    UseCanonicalName Off

LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# include part of the server name in the filenames
VirtualDocumentRoot "/home/%2/www"

# single cgi-bin directory
ScriptAlias  "/cgi-bin/"  "/www/std-cgi/"
    


    
    There are examples of more complicated
    VirtualDocumentRoot settings in the
    mod_vhost_alias documentation.
    


    top
    

    

    Using Multiple Virtual
  Hosting Systems on the Same Server
    

    
    With more complicated setups, you can use httpd's normal
    <VirtualHost> directives to control the
    scope of the various virtual hosting configurations. For
    example, you could have one IP address for general customers' homepages,
    and another for commercial customers, with the following setup.
    This can be combined with conventional
    <VirtualHost> configuration sections, as shown
    below.
    


    UseCanonicalName Off

LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon

<Directory "/www/commercial">
    Options FollowSymLinks
    AllowOverride All
</Directory>

<Directory "/www/homepages">
    Options FollowSymLinks
    AllowOverride None
</Directory>

<VirtualHost 111.22.33.44>
    ServerName www.commercial.example.com

    CustomLog "logs/access_log.commercial" vcommon

    VirtualDocumentRoot "/www/commercial/%0/docs"
    VirtualScriptAlias  "/www/commercial/%0/cgi-bin"
</VirtualHost>

<VirtualHost 111.22.33.45>
    ServerName www.homepages.example.com

    CustomLog "logs/access_log.homepages" vcommon

    VirtualDocumentRoot "/www/homepages/%0/docs"
    ScriptAlias         "/cgi-bin/" "/www/std-cgi/"
</VirtualHost>
    



    
    
    Note
    
    
    If the first VirtualHost block does not include a
    ServerName directive, the reverse
    DNS of the relevant IP will be used instead.
    If this is not the server name you
    wish to use, a bogus entry (eg. ServerName
    none.example.com) can be added to get around this
    behaviour.
    

    


    top
    

    

    More Efficient IP-Based Virtual Hosting
    

    
    The configuration changes suggested to turn the first
    example into an IP-based virtual hosting setup result in
    a rather inefficient setup. A new DNS lookup is required for every
    request. To avoid this overhead, the filesystem can be arranged to
    correspond to the IP addresses, instead of to the host names, thereby
    negating the need for a DNS lookup. Logging will also have to be adjusted
    to fit this system.
    


    # get the server name from the reverse DNS of the IP address
UseCanonicalName DNS

# include the IP address in the logs so they may be split
LogFormat "%A %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# include the IP address in the filenames
VirtualDocumentRootIP "/www/hosts/%0/docs"
VirtualScriptAliasIP  "/www/hosts/%0/cgi-bin"
    



    top
    

    

    Mass virtual hosts with
mod_rewrite
    


    
Mass virtual hosting may also be accomplished using
mod_rewrite, either using simple RewriteRule directives, or using more
complicated techniques such as storing the vhost definitions externally
and accessing them via RewriteMap. These techniques are
discussed in the rewrite
documentation.
    

    top
    

    

    Mass virtual hosts with mod_macro
    


    Another option for dynamically generated virtual hosts is
mod_macro, with which you can create a virtualhost
template, and invoke it for multiple hostnames. An example of this is
provided in the Usage section of the module
documentation.

    The term Virtual Host refers to the practice of
    running more than one web site (such as
    company1.example.com and company2.example.com)
    on a single machine. Virtual hosts can be "IP-based", meaning that you have a
    different IP address for every web site, or "name-based", meaning that you have
    multiple names running on each IP address. The fact that they
    are running on the same physical server is not apparent to the
    end user.
    

    
    Apache was one of the first servers to support IP-based
    virtual hosts right out of the box. Versions 1.1 and later of
    Apache support both IP-based and name-based virtual hosts
    (vhosts). The latter variant of virtual hosts is sometimes also
    called host-based or non-IP virtual hosts.
    

    
    Below is a list of documentation pages which explain all
    details of virtual host support in Apache HTTP Server:

    Configuration directives
    

    

    
    If you are trying to debug your virtual host configuration, you
    may find the -S command line switch
    useful.
    

    
    Unix example
    
    
    apachectl -S
    
    

    
    Windows example
    
    
    httpd.exe -S
    
    


    
    This command will dump out a description of how Apache parsed
    the configuration file. Careful examination of the IP addresses and
    server names may help uncover configuration mistakes. (See
    the docs for the httpd program for
    other command line options)

    virtuel de masse dynamique.
    
    


    


    top
    

    

    A qui ce document est-il destiné ?
    

    
    Les techniques décrites ici vous concernent si votre
    httpd.conf contient de nombreuses sections
    <VirtualHost> très semblables,
    dans le style :
    


    <VirtualHost 111.22.33.44>
    ServerName                 customer-1.example.com
    DocumentRoot        "/www/hosts/customer-1.example.com/docs"
    ScriptAlias  "/cgi-bin/" "/www/hosts/customer-1.example.com/cgi-bin"
</VirtualHost>

<VirtualHost 111.22.33.44>
    ServerName                 customer-2.example.com
    DocumentRoot        "/www/hosts/customer-2.example.com/docs"
    ScriptAlias  "/cgi-bin/" "/www/hosts/customer-2.example.com/cgi-bin"
</VirtualHost>

<VirtualHost 111.22.33.44>
    ServerName                 customer-N.example.com
    DocumentRoot        "/www/hosts/customer-N.example.com/docs"
    ScriptAlias  "/cgi-bin/" "/www/hosts/customer-N.example.com/cgi-bin"
</VirtualHost>
    


    
    Nous voulons remplacer toutes les configurations
    <VirtualHost> par un mécanisme qui les génère
    dynamiquement. Ceci présente certains avantages :
    

    
      
      
    1. Votre fichier de configuration est plus petit, ainsi Apache
      démarre plus rapidement et consomme moins de mémoire. Et ce qui
      est peut-être le plus important, le fichier de configuration plus
      petit est plus facile à maintenir, et le risque d'erreurs en est
      diminué d'autant.
      
      2. 

      
    2. Pour ajouter des serveurs virtuels, il suffit de créer les
      répertoires appropriés dans le système de fichiers et les entrées
      dans le DNS - il n'est plus nécessaire de reconfigurer ou de
      redémarrer Apache.
      3. 
    
    

    
    Le principal désavantage réside dans le fait que vous ne pouvez
    pas définir un fichier journal différent pour chaque serveur
    virtuel. De toute façon, ce serait une mauvaise idée si vous avez de
    nombreux serveurs virtuels, car cela nécessiterait un nombre important de descripteurs de
    fichier. Il est préférable de rediriger les journaux via un pipe ou
    une file fifo vers un
    programme, et faire en sorte que ce dernier éclate les journaux
    en un journal par serveur virtuel. L'utilitaire split-logfile
    constitue un exemple de ce traitement.
    


    top
    

    

    Vue d'ensemble
    

    
    Un serveur virtuel peut être défini par deux informations : son
    adresse IP, et le contenu de l'en-tête Host: de la
    requête HTTP. La technique d'hébergement virtuel dynamique de masse
    utilisée ici consiste à insérer automatiquement ces informations
    dans le chemin du fichier à utiliser pour répondre à la requête. On
    peut y parvenir assez facilement en utilisant
    mod_vhost_alias avec Apache httpd, mais on peut aussi
    utiliser mod_rewrite. 
    
    
    Par défaut, ces deux modules
    sont désactivés ; vous devez activer l'un d'eux lors de la
    compilation et de la configuration d'Apache httpd si vous voulez utiliser
    cette technique.
    

    
    Certains paramètres doivent être extraits de la requête pour que le serveur
    dynamique se présente comme un serveur dynamique normal. Le plus
    important est le nom du serveur, que le serveur utilise pour générer des
    URLs d'auto-référencement, etc... Il est défini via la directive
    ServerName, et les CGIs peuvent s'y référer via la
    variable d'environnement SERVER_NAME. Sa véritable
    valeur utilisée à l'exécution est contrôlée par la définition de la
    directive
    UseCanonicalName. Avec
    UseCanonicalName Off, le nom du serveur correspond au
    contenu de l'en-tête Host: de la requête. Avec
    UseCanonicalName DNS, il est extrait d'une recherche
    DNS inverse sur l'adresse IP du serveur virtuel. La première
    configuration est utilisée pour l'hébergement virtuel dynamique par
    nom, et la deuxième pour l'hébergement virtuel dynamique par IP. Si
    httpd ne peut pas déterminer le nom du serveur, soit parce qu'il
    n'y a pas d'en-tête Host:, soit parce que la recherche
    DNS a échoué, il prend en compte la valeur définie par la directive
    ServerName.
    

    
    L'autre paramètre à extraire est la racine des documents (définie
    via la directive DocumentRoot et disponible pour les
    scripts CGI via la variable d'environnement DOCUMENT_ROOT).
    Dans une configuration classique, il est utilisé par le module core
    pour faire correspondre les URIs aux noms de fichiers, mais lorsque
    la configuration du serveur comporte des serveurs virtuels, ce
    traitement doit être pris en charge par un autre module (soit
    mod_vhost_alias, soit mod_rewrite), qui
    utilise un méthode de correspondance différente. Aucun de ces
    modules ne se chargeant de définir la variable d'environnement
    DOCUMENT_ROOT, si des CGIs ou des documents SSI
    doivent en faire usage, ils obtiendront une valeur erronée.

    Hébergement virtuel
dynamique avec mod_vhost_alias
    

    
    Cet extrait de fichier httpd.conf implémente
    l'hébergement virtuel décrit dans la section À qui ce document est-il destiné ? ci-dessus
    en utilisant mod_vhost_alias.
    


    # extrait le nom du serveur de l'en-tête Host:
UseCanonicalName Off

# ce format de journal peut être éclaté en journaux par serveur virtuel
# à l'aide du premier champ via l'utilitaire split-logfile
LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# inclut le nom du serveur dans les noms de fichiers ressources
# nécessaires aux traitements des requêtes
VirtualDocumentRoot "/www/hosts/%0/docs"
VirtualScriptAlias  "/www/hosts/%0/cgi-bin"
    


    
    Pour changer cette configuration en solution de serveur virtuel
    par IP, il suffit de remplacer UseCanonicalName
    Off par UseCanonicalName DNS. Le nom du serveur
    inséré dans le nom de fichier sera alors déduit de l'adresse IP du
    serveur virtuel. La variable %0 fait référence au nom
    de serveur de la requête, tel qu'il est indiqué dans l'en-tête
    Host:.
    

    
    Voir la documentation du module mod_vhost_alias
    pour d'avantages d'exemples d'utilisation.

    Système de serveurs virtuels dynamiques
simplifié
    

    
    Il s'agit d'une adaptation du système ci-dessus, ajusté pour un
    serveur d'hébergement web de FAI. Grâce à la variable
    %2, on peut extraire des sous-chaînes de caractères du
    nom du serveur pour les utiliser dans le nom de fichier afin, par
    exemple, de définir /home/user/www comme emplacement des
    documents pour www.user.example.com. Un seul répertoire
    cgi-bin suffit pour l'ensemble des
    serveurs virtuels.
    


    UseCanonicalName Off

LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# insertion d'une partie du nom du serveur dans les noms de fichiers
VirtualDocumentRoot "/home/%2/www"

# répertoire cgi-bin unique
ScriptAlias  "/cgi-bin/"  "/www/std-cgi/"
    


    
    Vous trouverez des exemples plus élaborés d'utilisation de la
    directive VirtualDocumentRoot dans la documentation du
    module mod_vhost_alias.
    


    top
    

    

    Utiliser plusieurs systèmes
d'hébergement virtuel sur le même serveur
    

    
    Moyennant une configuration un peu plus compliquée, vous pouvez
    contrôler la portée des différentes configurations d'hébergement
    virtuel à l'aide des directives <VirtualHost>
    normales de httpd. Par exemple, on peut associer une adresse IP pour
    les pages d'accueil des clients en général, et une autre pour les
    clients commerciaux avec la configuration suivante. Cette
    configuration peut être combinée avec les sections
    <VirtualHost> conventionnelles, comme indiqué
    plus loin.
    


    UseCanonicalName Off

LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon

<Directory "/www/commercial">
    Options FollowSymLinks
    AllowOverride All
</Directory>

<Directory "/www/homepages">
    Options FollowSymLinks
    AllowOverride None
</Directory>

<VirtualHost 111.22.33.44>
    ServerName www.commercial.example.com
    
    CustomLog "logs/access_log.commercial" vcommon
    
    VirtualDocumentRoot "/www/commercial/%0/docs"
    VirtualScriptAlias  "/www/commercial/%0/cgi-bin"
</VirtualHost>

<VirtualHost 111.22.33.45>
    ServerName www.homepages.example.com
    
    CustomLog "logs/access_log.homepages" vcommon
    
    VirtualDocumentRoot "/www/homepages/%0/docs"
    ScriptAlias         "/cgi-bin/" "/www/std-cgi/"
</VirtualHost>
    



    
	
    Note
    
	
    Si le premier bloc VirtualHost ne comporte pas de
	directive ServerName, c'est
	le nom issu d'une recherche DNS inverse à partir de l'adresse IP
	du serveur virtuel qui sera utilisé. Si ce nom ne correspond pas
	à celui que vous voulez utiliser, vous pouvez ajouter une entrée
	de remplacement (par exemple ServerName
	none.example.com) pour éviter ce comportement.

    Pour un hébergement virtuel par IP plus
efficace
    

    
    Les changements de configuration suggérés pour transformer le premier exemple en hébergement virtuel par IP
    conduisent à une configuration peu efficace. Chaque requête
    nécessite une nouvelle recherche DNS. Pour éviter cette surcharge de
    travail, le système de fichiers peut être organisé pour correspondre
    aux adresses IP, plutôt qu'aux noms de serveurs, supprimant par
    la-même la nécessité d'une recherche DNS. La journalisation doit
    aussi être adaptée pour fonctionner sur un tel système.
    


    # obtention du nom du serveur par recherche DNS inverse
# sur l'adresse IP
UseCanonicalName DNS

# insertion de l'adresse IP dans les journaux afin de pouvoir les
# éclater
LogFormat "%A %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# insertion de l'adresse IP dans les noms de fichiers
VirtualDocumentRootIP "/www/hosts/%0/docs"
VirtualScriptAliasIP  "/www/hosts/%0/cgi-bin"

    Hébergement virtuel de masse avec
mod_rewrite
    


    
L'hébergement virtuel de masse peut aussi être effectué en utilisant
mod_rewrite, soit à l'aide de simples directives RewriteRule, soit en utilisant des
techniques plus compliquées comme le stockage externe des définitions
des serveurs virtuels, ces dernières étant accessibles via des
directives RewriteMap. Ces
techniques sont décrites dans la documentation sur la réécriture.
    


    top
    

    

    Hébergement virtuel en masse avec mod_macro
    


    Une autre option pour générer dynamiquement des serveurs virtuels :
mod_macro ; ce module permet de créer un modèle de serveur virtuel que
vous pourrez invoquer pour des noms d'hôtes multiples. La section
Usage de la documentation du module présente un exemple qui
illustre cette méthode.

    たくさんのバーチャルホストを運用する場合、もし、
    各バーチャルホストごとに異なるログファイルが指定してあると、
    Apache がファイル記述子 (ファイルハンドルとも呼ばれます)
    を使い切ってしまうことがあります。Apache が使用するファイル
    記述子の数は、各エラーログファイルにつき 1 つ、他のログファイルの
    ディレクティブにつき 1 つ、さらに内部で使用する 10 から 20、
    の合計になります。Unix オペレーティングシステムではプロセスごとに
    使用可能なファイル記述子の数を制限しています。たいていの場合は 64 で、
    普通は大きな値のハードリミットまで増やすことができます。
    

    
    Apache は必要に応じて上限を拡大しようと試みますが、
    以下のような場合にはうまくいかないかもしれません。
    

    
      
      
    1. 利用しているシステムで setrlimit()
      システムコールが提供されていない。
      2. 

      
    2. システム上で setrlimit(RLIMIT_NOFILE) が動作しない
      (たとえば Solaris 2.3 のように)。
      3. 

      
    3. 要求されるファイル記述子の数が
      ハードリミットを超えてしまう。
      4. 
      
      
    4. システムにファイル記述子に関して別の制限が存在してしまっている。
      たとえば、stdio ストリームではファイル記述子を 256 以上使えない
      (Solaris 2)、など。
      5. 
    
    

    
    問題が発生した時に取り得る対処方法は次のとおり:
    

    
      
      
    • ログファイルの数を減らす。<VirtualHost>
      セクションでログファイルを指定せず、メインのログファイルにのみ記録する。
      (これに関する詳しい情報は以下のログファイルの分割を読んでください。)
      • 

      
    • 
        もし、前述の 1 または 2 の場合であれば、
        Apache を起動する前にファイル記述子を増やします。
        たとえば次のようなスクリプトを使います。

        
      
          #!/bin/sh
      
           ulimit -S -n 100
      
           exec httpd      
        
      
      
      • 
    
    

    

    top
    

    

    ログファイルの分割
    


    複数のバーチャルホストのログを同じログファイルに収集しようとしているときには、
各バーチャルホストについて統計的な解析を実行するために後でログファイルを
分割したくなるかもしれません。これは以下のようにして実現できます。
    


    まず、バーチャルホストの情報をログのエントリに追加する必要があります。
これは LogFormat
ディレクティブの %v 変数を使うことでできます。
これをログのフォーマット文字列の先頭に追加します:
    


    
LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost
    
CustomLog logs/multiple_vhost_log vhost

    


    これは common log format のログを作成しますが、それぞれの行の先頭に
正規化されたバーチャルホストの名前
(ServerName
ディレクティブに書かれているもの) が付加されます。
(ログファイルのカスタマイズの詳細については Custom Log Formats を
読んでください。)
    


    ログファイルを各部分 (バーチャルホスト毎に 1 ファイル) に分けたいときは、
split-logfile
を使って行なうことができます。プログラムは Apache 配布の 
support ディレクトリにあります。
    


    以下のようなコマンドでこのプログラムを実行します:
    


    
split-logfile < /logs/multiple_vhost_log

    


    このプログラムはバーチャルホストのログファイルの名前とともに実行され、
ログファイルに現れるそれぞれのバーチャルホスト毎に一つのファイルを作成します。
それぞれのファイルは ホスト名.log という名前になります。

    İsme dayalı ve IP’ye dayalı Sanal Konaklar
    

    
    IP’ye dayalı sanal konaklarda sunulacak
      sanal konağı doğru tespit edebilmek için bağlantının yapıldığı IP
      adresine bakılır. Bu bakımdan her konak için ayrı bir IP adresine
      gereksinim vardır.
    

    
    İsme dayalı sanal konaklarda ise sunucu, istemcinin HTTP başlığının bir
      parçası olarak gönderdiği konak adını kullanır. Bu teknikte aynı IP
      adresini çok sayıda farklı konak kullanabilir.
    

    
    İsme dayalı sanal barındırma nispeten daha kolaydır, çünkü her konak
      ismini doğru IP adresiyle eşlemek için DNS sunucunuzu yapılandırdıktan
      sonra Apache HTTP sunucusunu farklı konak isimlerini tanıyacak şekilde
      yapılandırmanız yeterli olur. İsme dayalı sanal barındırma ayrıca zaten
      kıt olan IP adreslerine talebi de azaltır. Bu nedenle, IP’ye dayalı sanal
      konakları kullanmanızı gerektiren donanım kullanmadıkça isme  dayalı
      sanal konaklar kullanmalısınız. İstemci uyumuna bağlı IP’ye dayalı
      sanal barındırma için eskiden varolan sebepler genel amaçlı bir HTTP
      sunucusu için artık uygulanabilir değildir.
    

    
    İsme dayalı sanal barındırma, IP'ye dayalı sanal barındırma seçim
      algoritmasını kullanmaz, yani uygun sunucu ismini arama işlemi sadece en
      iyi IP'ye dayalı adrese sahip sanal konaklar arasında gerçekleşir.
    


    top
    

    

    Sunucu isme dayalı sanal konaklardan uygun olanını nasıl seçer
    
  

    
    İsme dayalı sanal konak çözümlemesinin ilk adımının IP'ye dayalı
      çözümleme olduğunun anlaşılması çok önemlidir. İsme dayalı sanal konak
      çözümlemesi en uygun isme dayalı sanal konağı seçerken önce en iyi IP'ye
      dayalı eşleşme adaylarının sayısını azaltır, sonra bunlar arasından en
      uygununu seçer. Tüm VirtualHost yönergelerinde IP adresi
      yerine joker kullanımı bu IP'ye dayalı eşlemeyi yersiz kılar.
    

    
    Bir istek geldiğinde, sunucu, istekte kullanılan IP adresi ve portu ile
      en iyi eşleşen <VirtualHost> bileşenini bulur. Bu IP adresi ve port çifti ile
      eşleşen birden fazla sanal konak varsa, Apache httpd istekte kullanılan
      sunucu ismini ServerName ve
      ServerAlias yönergelerindeki
      isimlerle karşılaştırır.
    

    
    Herhangi bir isme dayalı sanal konakta ServerName yönergesini kullanmazsanız, sunucu
      bu yönergeye sistem konak adından türetilmiş tam nitelenmiş alan adının
      (FQDN) tanımlandığını varsayacaktır. Bu örtük atama sezgiselliğin
      istenmediği bir sanal konak eşleşmesi ile sonuçlanabilir ve bu
      önerilmez.
    

  
    Bir IP adresi ve port çifti için öntanımlı isme dayalı sankon
    
   
    
    ServerName ve
      ServerAlias yönergelerinde bir
      eşleşme bulunamazsa, Apache httpd bu çift ile eşleşen sanal
      konaklar listesindeki ilk sanal konağı kullanır.

    İsme Dayalı Sanal Konakların Kullanımı
    


    İlgili Modüllerİlgili Yönergeler
    

    
    İlk adım sunacağınız her konak için ayrı bir <VirtualHost> bölümü oluşturmaktır. Her
      <VirtualHost> bölümü
      içinde sunulan konağı belirtmek üzere en azından bir adet ServerName yönergesine ve konak içeriğinin
      dosya sisteminde bulunduğu yeri gösteren bir DocumentRoot yönergesine ihtiyacınız
      olacaktır.
    

    
    Ana konağı unutmayın
    
      
    Mevcut <VirtualHost>
        yönergelerinin hiçbiriyle eşleşmeyen bir istek için, sunucu veya konak
        ismine bakılmaksızın genel sunucu yapılandırmanız kullanılır.
    

      
    Mevcut sitenize isme dayalı bir sanal konak eklerseniz ve bu sanal
        konak ana sunucunun IP adresi ve portuna sahipse, ana sunucuya yapılan
        istekler için bu sanal konak kullanılır. Bu bakımdan, ServerName yönergesi ana sunucununki ile aynı
        olan bir öntanımlı sanal konak oluşturmak
        akıllıca olacaktır. Aynı arayüz ve portu kullanan fakat farklı
        yapılandırmalara sahip diğer alan isimlerinin sanal konakları (yani
        öntanımlı olmayanlar) bu öntanımlı sanal konağın sonrasına
        yerleştirilmelidir.
    
    
    

    
    ServerName miras alma
    
       
    İsme dayalı her sanal konak için daima bir ServerName belirtmek en iyisidir.
    

       
    Eğer bir VirtualHost bölümü
       içinde bir ServerName
       belirtilmezse, sunucu ismi olarak ana sunucu yapılandırmasındaki isim
       kullanılır. Orada da bir sunucu ismi belirtilmemişse, başlatma sırasında
       dinlenen ilk IP adresinden ters DNS araması ile elde edilen isim
       kullanılır. Her iki durumda da miras alınan isim gereksiz yere isme
       dayalı sanal konak ismi haline gelecektir; bu bakımdan isme dayalı her
       sanal konak için daima bir ServerName belirtmek en iyisidir.
    
    
    

    
    Örnek olarak, site1.example.com adresinden sitenizi
      sunmakta olduğunuzu ve bunun yanına aynı IP adresini kullanan
      site2.example.com sanal konağını eklemek istediğinizi
      varsayalım. Bunun için httpd.conf dosyanıza basitçe şu
      satırları ekleyebilirsiniz:
    

    
    <VirtualHost *:80>
    #İlk sanal konak aynı zamanda *:80 için de öntanımlıdır.
    ServerName site1.example.com
    ServerAlias example.com
    DocumentRoot "/siteler/site1"
</VirtualHost>

<VirtualHost *:80>
    ServerName site2.example.com
    DocumentRoot "/siteler/site2"
</VirtualHost>
    


    
    İsterseniz, <VirtualHost> yönergesinde argüman olarak *
      yerine doğrudan bir IP adresi belirtebilirsiniz. Hatta, daha sonra, isme
      dayalı sanal konakları bir IP adresinden ve IP’ye dayalı olanları veya
      isme dayalı diğer bir sanal konak grubunu diğer IP adreslerinden sunmak
      isteyebilirsiniz.
    

    
    Çoğu sunucunun birden fazla isim ile erişilebilir olması istenir. Bu,
      <VirtualHost> bölümü
      içine bir ServerAlias yönergesi
      yerleştirmek suretiyle mümkün olur. Örneğin yukarıdaki örnekte,
      kullanıcıların aynı siteye farklı isimlerle erişmelerini mümkün kılmak
      için bölüm içine şu satırı ekleyebilirsiniz:
    

    
    ServerAlias example.com *.example.com
    


    
    Böylece example.com alanındaki tüm konaklar için gelen
      isteklere www.example.com sanal konağından hizmet sunulmuş
      olur. Konak isimleriyle eşleşmek üzere dosya ismi kalıp karakterleri
      * ve ? kullanılabilir. Şüphesiz bu isimleri
      sırf ServerName veya
      ServerAlias yönergesinde belirtmiş olmakla bu isimleri
      erişilebilir kılamazsınız. Öncelikle, bu isimleri sunucunuzdaki IP
      adresleriyle eşlemek üzere yapılandıracağınız bir DNS sunucunuz
      olmalıdır.
    

    
    İsme dayalı sanal konaklardan en iyi eşleşme kümesinde olanlar
      yapılandırmada göründükleri sıraya göre işleme sokulur. Joker
      kullanımları arasında fark gözetilmeksizin ServerName veya ServerAlias yönergesi eşleşen ilk sanal konak
      kullanılır.
    

    
    VirtualHost içindeki isimlerin sırası (jokersiz) bir
      ServerAlias gibi ele alınır (fakat hiçbir
      ServerAlias yönergesi ile geçersiz kılınmaz).
    

    
    Son olarak, sanal konak yapılandırmanıza, <VirtualHost> bölümlerinin içine başka yönergeler
      yerleştirerek ince ayar çekebilirsiniz. Çoğu yönerge bu bölümlere
      yerleştirilebilir ve sadece o sanal konakla ilgili yapılandırmayı
      değiştirmek için kullanılabilir. Belli bir yönergenin sanal konak
      bölümlerinde kullanılıp kullanılmayacağını yönergenin açıklamasında Bağlam satırına bakarak
      öğrenebilirsiniz. Ana sunucu bağlamındaki (<VirtualHost> bölümleri dışındaki)
      yapılandırma yönergelerinden sadece sanal konak bölümlerinde geçersiz
      kılınmamış olanlar kullanılacaktır.

    This document attempts to answer the commonly-asked questions about
    setting up virtual hosts. These scenarios are those involving multiple
    web sites running on a single server, via name-based or IP-based virtual hosts.
    
    


    


    top
    

    

    Running several name-based web
    sites on a single IP address.
    

    
    Your server has multiple hostnames that resolve to a single address,
    and you want to respond differently for www.example.com
    and www.example.org.
    

    
    Note
    Creating virtual
          host configurations on your Apache server does not magically
          cause DNS entries to be created for those host names. You
          must have the names in DNS, resolving to your IP
          address, or nobody else will be able to see your web site. You
          can put entries in your hosts file for local
          testing, but that will work only from the machine with those
          hosts entries.
    
    
    

    
    # Ensure that Apache listens on port 80
Listen 80
<VirtualHost *:80>
    DocumentRoot "/www/example1"
    ServerName www.example.com

    # Other directives here
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/www/example2"
    ServerName www.example.org

    # Other directives here
</VirtualHost>
    


    
    The asterisks match all addresses, so the main server serves no
    requests. Due to the fact that the virtual host with
    ServerName www.example.com is first
    in the configuration file, it has the highest priority and can be seen
    as the default or primary server. That means
    that if a request is received that does not match one of the specified
    ServerName directives, it will be served by this first
    <VirtualHost>.
    

    
    The above configuration is what you will want to use in almost
    all name-based virtual hosting situations. The only thing that this
    configuration will not work for, in fact, is when you are serving
    different content based on differing IP addresses or ports.
    

    
    
            
    Note
    

           
    You may replace * with a specific IP address
           on the system.  Such virtual hosts will only be used for
           HTTP requests received on connection to the specified IP
           address.
    

           
    However, it is additionally useful to use *
           on systems where the IP address is not predictable - for
           example if you have a dynamic IP address with your ISP, and
           you are using some variety of dynamic DNS solution. Since
           * matches any IP address, this configuration
           would work without changes whenever your IP address
           changes.
    
    
    
  
    top
    

    

    Name-based hosts on more than one
    IP address.
    

    
    
      
    Note
    
      
    Any of the techniques discussed here can be extended to any
      number of IP addresses.
    
    
    

    
    The server has two IP addresses. On one (172.20.30.40), we
    will serve the "main" server, server.example.com and on the
    other (172.20.30.50), we will serve two or more virtual hosts.
    

    
    Listen 80

# This is the "main" server running on 172.20.30.40
ServerName server.example.com
DocumentRoot "/www/mainserver"

<VirtualHost 172.20.30.50>
    DocumentRoot "/www/example1"
    ServerName www.example.com

    # Other directives here ...
</VirtualHost>

<VirtualHost 172.20.30.50>
    DocumentRoot "/www/example2"
    ServerName www.example.org

    # Other directives here ...
</VirtualHost>
    


    
    Any request to an address other than 172.20.30.50 will be
    served from the main server. A request to 172.20.30.50 with an
    unknown hostname, or no Host: header, will be served from
    www.example.com.
    

  
    top
    

    

    Serving the same content on
    different IP addresses (such as an internal and external
    address).
    

    
    The server machine has two IP addresses (192.168.1.1
    and 172.20.30.40). The machine is sitting between an
    internal (intranet) network and an external (internet) network. Outside
    of the network, the name server.example.com resolves to
    the external address (172.20.30.40), but inside the
    network, that same name resolves to the internal address
    (192.168.1.1).
    

    
    The server can be made to respond to internal and external requests
    with the same content, with just one <VirtualHost> section.
    

    
    <VirtualHost 192.168.1.1 172.20.30.40>
    DocumentRoot "/www/server1"
    ServerName server.example.com
    ServerAlias server
</VirtualHost>
    


    
    Now requests from both networks will be served from the same
    <VirtualHost>.
    

    
    
          
    Note:
    On the internal
          network, one can just use the name server rather
          than the fully qualified host name
          server.example.com.
    

          
    Note also that, in the above example, you can replace the list
          of IP addresses with *, which will cause the server to
          respond the same on all addresses.
    
    
    

  
    top
    

    

    Running different sites on different
    ports.
    

    
    You have multiple domains going to the same IP and also want to
    serve multiple ports.  The example below illustrates that the name-matching
    takes place after the best matching IP address and port combination
    is determined.
    

    
    Listen 80
Listen 8080

<VirtualHost 172.20.30.40:80>
    ServerName www.example.com
    DocumentRoot "/www/domain-80"

    www.example.com and www.example.org
    respectively.

    Requests for any address not specified in one of the
    <VirtualHost> directives (such as

    The server machine has two IP addresses (172.20.30.40 and
    172.20.30.50) which resolve to the names
    www.example.com and www.example.org
    respectively. In each case, we want to run hosts on ports 80 and
    8080.

    Using Virtual_host and
    mod_proxy together
    

    
    The following example allows a front-end machine to proxy a
    virtual host through to a server running on another machine. In the
    example, a virtual host of the same name is configured on a machine
    at 192.168.111.2. The ProxyPreserveHost
    On directive is used so that the desired hostname is
    passed through, in case we are proxying multiple hostnames to a
    single machine.
    

    
    <VirtualHost *:*>
    ProxyPreserveHost On
    ProxyPass        "/" "http://192.168.111.2/"
    ProxyPassReverse "/" "http://192.168.111.2/"
    ServerName hostname.example.com
</VirtualHost>
    


    
    top
    

    

    Using _default_
    vhosts
    

    
    _default_ vhosts
    for all ports
    

    
    Catching every request to any unspecified IP address and
    port, i.e., an address/port combination that is not used for
    any other virtual host.
    

    
    <VirtualHost _default_:*>
    DocumentRoot "/www/default"
</VirtualHost>
    


    
    Using such a default vhost with a wildcard port effectively prevents
    any request going to the main server.
    

    
    A default vhost never serves a request that was sent to an
    address/port that is used for name-based vhosts. If the request
    contained an unknown or no Host: header it is always
    served from the primary name-based vhost (the vhost for that
    address/port appearing first in the configuration file).
    

    
    You can use AliasMatch or
    RewriteRule to rewrite any
    request to a single information page (or script).
    
    

    
    _default_ vhosts
    for different ports
    

    
    Same as setup 1, but the server listens on several ports and we want
    to use a second _default_ vhost for port 80.
    

    
    <VirtualHost _default_:80>
    DocumentRoot "/www/default80"
    # ...
</VirtualHost>

<VirtualHost _default_:*>
    DocumentRoot "/www/default"
    # ...
</VirtualHost>
    


    
    The default vhost for port 80 (which must appear before any
    default vhost with a wildcard port) catches all requests that were sent
    to an unspecified IP address. The main server is never used to serve a
    request.
    
    

    
    _default_ vhosts
    for one port
    

    
    We want to have a default vhost for port 80, but no other default
    vhosts.
    

    
    <VirtualHost _default_:80>
    DocumentRoot "/www/default"
...
</VirtualHost>
    


    
    A request to an unspecified address on port 80 is served from the
    default vhost. Any other request to an unspecified address and port is
    served from the main server.
    

    
    Any use of * in a virtual host declaration will have
    higher precedence than _default_.
    

    

  
    top
    

    

    Migrating a name-based vhost to an
    IP-based vhost
    

    
    The name-based vhost with the hostname
    www.example.org (from our name-based example, setup 2) should get its own IP
    address. To avoid problems with name servers or proxies who cached the
    old IP address for the name-based vhost we want to provide both
    variants during a migration phase.
    

    
    
     The solution is easy, because we can simply add the new IP address
    (172.20.30.50) to the VirtualHost
    directive.
    

    
    Listen 80
ServerName www.example.com
DocumentRoot "/www/example1"

<VirtualHost 172.20.30.40 172.20.30.50>
    DocumentRoot "/www/example2"
    ServerName www.example.org
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/www/example3"
    ServerName www.example.net
    ServerAlias *.example.net
    # ...
</VirtualHost>
    


    
    The vhost can now be accessed through the new address (as an
    IP-based vhost) and through the old address (as a name-based
    vhost).
    

  
    top
    

    

    Using the ServerPath
  directive
    

    
    We have a server with two name-based vhosts. In order to match the
    correct virtual host a client must send the correct Host:
    header. Old HTTP/1.0 clients do not send such a header and Apache has
    no clue what vhost the client tried to reach (and serves the request
    from the primary vhost). To provide as much backward compatibility as
    possible we create a primary vhost which returns a single page
    containing links with an URL prefix to the name-based virtual
    hosts.
    

    
    <VirtualHost 172.20.30.40>
    # primary vhost
    DocumentRoot "/www/subdomain"
    RewriteEngine On
    RewriteRule "." "/www/subdomain/index.html"
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/www/subdomain/sub1"
    ServerName www.sub1.domain.tld
    ServerPath "/sub1/"
    RewriteEngine On
    RewriteRule "^(/sub1/.*)" "/www/subdomain$1"
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/www/subdomain/sub2"
    ServerName www.sub2.domain.tld
    ServerPath "/sub2/"
    RewriteEngine On
    RewriteRule "^(/sub2/.*)" "/www/subdomain$1"
    # ...
</VirtualHost>
    


    
    Due to the ServerPath
    directive a request to the URL
    http://www.sub1.domain.tld/sub1/ is always served
    from the sub1-vhost.
     A request to the URL
    http://www.sub1.domain.tld/ is only
    served from the sub1-vhost if the client sent a correct
    Host: header. If no Host: header is sent the
    client gets the information page from the primary host.
    

    
    Please note that there is one oddity: A request to
    http://www.sub2.domain.tld/sub1/ is also served from the
    sub1-vhost if the client sent no Host: header.
    

    
    The RewriteRule directives
    are used to make sure that a client which sent a correct
    Host: header can use both URL variants, i.e.,
    with or without URL prefix.

    术语虚拟主机指的是在单一机器上运行多个网站
    (例如 company1.example.com 和
    company2.example.com) 。
    虚拟主机可以“基于 IP”，即每个 IP 一个站点；
    或者“基于名称”，
    即每个 IP 多个站点。这些站点运行在同一物理服务器上的事实不会明显的透漏给最终用户。
    

    
    Apache 是第一个支持基于 IP 的虚拟主机的服务器。
    Apache 版本 1.1 和更新的版本同时支持基于 IP 和基于名称的虚拟主机。
    基于名称的虚拟主机有时候称为基于主机或非 IP 的虚拟主机.
    

    
    以下解释是在 Apache 中支持虚拟主机的所有详细信息的文档页面列表。

    配置指令
    

    

    
    如果你要调试虚拟主机配置，你会发现 Apache 的命令行参数 -S
    非常有用。即输入以下命令:
    

    
    
    /usr/local/apache2/bin/httpd -S
    
    

    
    这个命令将会显示 Apache 是如何解析配置文件的。仔细检查 IP
    地址与服务器名称可能会帮助你发现配置错误
    (参见 httpd 程序文档，以便了解其它命令行选项)。

    Diese Übersetzung ist möglicherweise
            nicht mehr aktuell. Bitte prüfen Sie die englische Version auf
            die neuesten Änderungen.
    

    
    Der Begriff virtueller Host (Anm.d.Ü.: engl. 'virtual
    host') bezieht sich auf die Praxis, mehr als ein Webangebot
    (z.B. www.company1.com und www.company2.com)
    auf einer einzigen Maschine zu betreiben. Virtuelle Hosts können
    "IP-basiert" sein, was bedeutet, dass jedes
    Webangebot eine andere IP besitzt, oder  "Namens-basiert", was bedeutet, dass
    unter jeder IP-Adresse mehrere Namen laufen. Die Tatsache, dass sie
    auf dem gleichen physischen Server laufen, ist für den Endbenutzer
    nicht offensichtlich.
    

    
    Der Apache war einer der ersten Server, der IP-basierte
    virtuelle Hosts von Haus aus direkt unterstützt hat. Seit Version 1.1
    unterstützt der Apache sowohl IP-basierte als auch namensbasierte
    virtuelle Hosts (vhosts). Letzteres wird zuweilen auch
    Host-basiert oder non-IP-Virtual-Host genannt.
    

    
    Nachfolgend finden Sie eine Liste von Dokumenten, die alle Details
    der Unterstützung von virtuellen Hosts ab Apache Version 1.3
    beschreiben.

    Konfigurationsdirektiven
    

    

    
    Bei der Suche von Fehlern in Ihrer Virtual-Host-Konfiguration ist
    die Apache-Befehlszeilenoption -S möglicherweise
    hilfreich. Geben Sie dazu den folgenden Befehl ein:
    

    
    
    /usr/local/apache2/bin/httpd -S
    
    

    
    Diese Anweisung gibt eine Beschreibung aus, wie der Apache die
    Konfigurationsdatei analysiert hat. Eine sorgfältige
    Überprüfung der IP-Adressen und Servernamen kann helfen,
    Konfigurationsfehler aufzudecken. (Lesen Sie die Dokumentation zum
    httpd-Programm für weitere
    Befehlszeilenoptionen.)

    Système requis
    

    
    Comme l'indique le terme par IP, le serveur
    doit disposer de différentes paires adresses IP/port pour chaque
    serveur virtuel par IP. La machine peut posséder
    plusieurs connexions physiques au réseau, ou utiliser des
    interfaces virtuelles qui sont supportées par la plupart des
    systèmes d'exploitation modernes (Consultez la documentation des
    systèmes d'exploitation pour plus de détails, notamment les "alias
    IP" et la commande "ifconfig" pour les activer), et/ou utiliser
    plusieurs numéros de port.
    

    
    Selon la terminologie du serveur HTTP Apache, l'utilisation d'une
    seule adresse IP avec plusieurs ports TCP s'apparente aussi à de
    l'hébergement virtuel basé sur IP.
    

    top
    

    

    Comment configurer Apache
    

    
    Il y a deux manières de configurer Apache pour le support de
    multiples serveurs virtuels. Il suffit soit de faire tourner un
    processus résident httpd pour chaque nom de
    domaine, soit de faire tourner un unique processus résident qui
    gère tous les serveurs virtuels.
    

    
    Utilisez des processus résidents multiples lorsque :
    

    
      
      
    • il y a des problèmes de répartition de sécurité, tels
      qu'une entreprise1 ne souhaite que personne d'une entreprise2
      ne puisse lire ses données excepté via le Web. Dans ce cas,
      vous aurez besoin de deux processus résidents, chacun fonctionnant
      avec des paramètres User,
      Group,
      Listen, et
      ServerRoot différents.
      • 

      
    • vous disposez suffisamment de mémoire et de
      descripteurs de fichiers
      pour l'écoute de chaque alias IP de la machine. Il est seulement
      possible d'appliquer la directive
      Listen, soit sur toutes
      les adresses avec le joker "*", soit uniquement sur des adresses
      spécifiques. Donc, si vous avez besoin d'écouter une adresse
      en particulier, vous devrez le faire pour l'ensemble des
      autres adresses (Bien qu'il soit plus simple de lancer un
      processus httpd pour écouter N-1 adresses,
      et un autre pour l'adresse restante).
      • 
    
    

    
    Utilisez un unique processus résident lorsque :
    

    
      
      
    • le partage de la configuration httpd entre les serveurs
      virtuels est acceptable.
      • 

      
    • la machine assume déjà une grande quantité de requêtes, et
      que l'ajout de processus résidents supplémentaires en affecterait
      les performances.
      • 
    
    


    top
    

    

    Configuration de processus multiples
    

    
    Créez une installation indépendante du programme
    httpd pour chaque serveur virtuel. Pour
    chacune d'elle, utilisez la directive
    Listen dans le fichier
    de configuration pour définir l'adresse IP (ou serveur virtuel)
    que le processus résident doit gérer. Par exemple :
    

    
    Listen 192.0.2.100:80
    


    
    Il est recommandé d'utiliser une adresse IP plutôt qu'un nom
    de domaine (consultez Problèmes DNS
    avec Apache).
    


    top
    

    

    Configuration d'un unique processus
résident pour des serveurs virtuels
    

    
    Dans ce cas, un unique processus httpd va gérer les requêtes
    pour le serveur principal et tous les serveurs virtuels. Dans le
    fichier de configuration, la directive
    VirtualHost va servir à
    définir les autres directives
    ServerAdmin,
    ServerName,
    DocumentRoot,
    ErrorLog et
    TransferLog ou
    CustomLog avec des
    valeurs différentes pour chaque serveur virtuel. Par exemple :
    

    
    <VirtualHost 172.20.30.40:80>
    ServerAdmin webmaster@www1.example.com
    DocumentRoot "/www/vhosts/www1"
    ServerName www1.example.com
    ErrorLog "/www/logs/www1/error_log"
    CustomLog "/www/logs/www1/access_log" combined
</VirtualHost>

<VirtualHost 172.20.30.50:80>
    ServerAdmin webmaster@www2.example.org
    DocumentRoot "/www/vhosts/www2"
    ServerName www2.example.org
    ErrorLog "/www/logs/www2/error_log"
    CustomLog "/www/logs/www2/access_log" combined
</VirtualHost>
    


    
    Il est recommandé d'utiliser une adresse IP plutôt qu'un nom
    de domaine comme argument à la directive <VirtualHost>
     (consultez Problèmes DNS
    avec Apache).
    

    
    Presque toutes les directives de configuration
    peuvent être employées dans une directive VirtualHost, à l'exception
    des directives qui contrôlent la création du processus et de
    quelques autres. Pour connaître celles utilisables dans une
    directive VirtualHost, vérifiez leur
    Contexte en utilisant
    l'directive index.
    


    
    SuexecUserGroup peut être
    utilisées à l'intérieur d'une directive VirtualHost si l'exécution se fait
    sous suEXEC. (Voir suEXEC).
    

    
    SÉCURITÉ : lorsque vous spécifiez où écrire les
    fichiers journaux, soyez attentif aux risques si quelqu'un d'autre
    que celui qui a démarré Apache dispose des droits d'écriture
    sur l'emplacement de ces fichiers. Consultez les
    Conseils sur la sécurité
    pour plus de détails.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    


    
    バーチャルホストという用語は、1 台のマシン上で
    (www.company1.com and www.company2.com のような)
    二つ以上のウェブサイトを扱う運用方法のことを指します。
    バーチャルホストには、各ウェブサイトに違う IP アドレスがある
    「IP ベース」と、それぞれの IP アドレスに
    複数の名前がある「名前ベース」とがあります。
    複数のサイトが物理的に同じサーバで扱われている、ということはエンドユーザには
    明らかではありません。
    

    
    Apache は、特に手を入れない状態で IP ベースのバーチャルホスト
    をサポートした最初のサーバの一つです。バージョン 1.1 以降の Apache
    では、IP ベースとネームベースのバーチャルホストの両方をサポート
    しています。ネームベースのバーチャルホストは、ホストベースあるいは
    非 IP ベースのバーチャルホストと呼ばれることもあります。
    

    
    以下のページでは、Apache バージョン 1.3
    以降でのバーチャルホストのサポートについての詳細を説明します。

    設定ディレクティブ
    

    

    
    バーチャルホストの設定のデバッグをするには
    Apache のコマンドラインスイッチ -S が便利です。
    つまり、以下のコマンドを入力します:
    

    
    
    /usr/local/apache2/bin/httpd -S
    
    

    
    このコマンドは Apache が設定ファイルをどう解析したかについて出力します。
    IP アドレスとサーバ名を注意深く調べれば、
    設定の間違いを見つける助けになるでしょう。
    (他のコマンドラインのオプションは httpd
    プログラムの説明文書を見てください)

    File Descriptor Limits

    When using a large number of Virtual Hosts, Apache may run
    out of available file descriptors (sometimes called file
    handles) if each Virtual Host specifies different log
    files. The total number of file descriptors used by Apache is
    one for each distinct error log file, one for every other log
    file directive, plus 10-20 for internal use. Unix operating
    systems limit the number of file descriptors that may be used
    by a process; the limit is typically 64, and may usually be
    increased up to a large hard-limit.
    

    
    Although Apache attempts to increase the limit as required,
    this may not work if:
    

    
      
      
    1. Your system does not provide the setrlimit()
      system call.
      2. 

      
    2. The setrlimit(RLIMIT_NOFILE) call does not
      function on your system (such as Solaris 2.3)
      3. 

      
    3. The number of file descriptors required exceeds the hard
      limit.
      4. 

      
    4. Your system imposes other limits on file descriptors,
      such as a limit on stdio streams only using file descriptors
      below 256. (Solaris 2)
      5. 
    
    

    
    In the event of problems you can:
    

    
      
      
    • Reduce the number of log files; don't specify log files
      in the <VirtualHost>
      sections, but only log to the main log files. (See Splitting up your log files, below, for more
      information on doing this.)
      • 

      
    • 
        If your system falls into 1 or 2 (above), then increase the
        file descriptor limit before starting Apache, using a
        script like:

        
      
          #!/bin/sh
      
           ulimit -S -n 100
      
           exec httpd      
        
      
      
      •

    Splitting up your log files
    


    If you want to log multiple virtual hosts to the same log file, you
may want to split up the log files afterwards in order to run
statistical analysis of the various virtual hosts. This can be
accomplished in the following manner.
    


    First, you will need to add the virtual host information to the log
entries. This can be done using the 
LogFormat
directive, and the %v variable. Add this to the beginning
of your log format string:
    


    LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost
CustomLog logs/multiple_vhost_log vhost
    



    This will create a log file in the common log format, but with the
canonical virtual host (whatever appears in the
ServerName directive) prepended to
each line. (See mod_log_config for
more about customizing your log files.)
    


    When you wish to split your log file into its component parts (one
file per virtual host), you can use the program split-logfile to accomplish
this. You'll find this program in the support directory
of the Apache distribution.
    


    Run this program with the command:
    


    
split-logfile < /logs/multiple_vhost_log

    


    This program, when run with the name of your vhost log file, will
generate one file for each virtual host that appears in your log file.
Each file will be called hostname.log.

    Sanal Konak (Virtual Host) terimi tek bir makine üzerinde
      birden fazla sitenin (sirket1.example.com, sirket2.example.com gibi)
      barındırılma uygulamasını betimler. Sanal konaklar,
      "IP’ye dayalı" veya
      "isme dayalı" olabilir;
      birincisinde, her site ayrı bir IP adresinden sunulurken, ikincisinde her
      IP adresinde birden fazla site sunulur. Olayda aynı fiziksel sunucu
      kullanıldığı halde bu sunucu son kullanıcıya görünür değildir.
    

    
    Apache yazılımsal olarak IP’ye dayalı sanal konakları destekleyen ilk
      sunuculardan biridir. 1.1 sürümünden itibaren Apache hem IP’ye dayalı hem
      de isme dayalı sanal konakları desteklemektedir. İsme dayalı sanal
      konaklara bazen konağa dayalı sanal konaklar veya IP’ye
      dayanmayan sanal konaklar da denmektedir.
    

    
    Aşağıda, Apache HTTP Suncusundaki sanal konak desteğini bütün
      ayrıntıları ile açıklayan belgeler listelenmiştir.

    Yapılandırma Yönergeleri
    

    

    
    Sanal konak yapılandırmanız üzerinde hata ayıklamaya çalışıyorsanız
      -S komut satırı seçeneği şu şekilde çok işinize
      yarayabilir:
    

    
    Unix örneği
    
    apachectl -S
    
    

    
    Windows örneği
    
    httpd.exe -S
    
    
    
    
    Bu komut, yapılandırma dosyasının Apache yorumunu dökümler. IP
      adreslerinin ve sunucu isimlerinin dikkatli bir incelemesi, yapılandırma
      yanlışlarınızı keşfetmenize yardımcı olabilir. (Diğer komut satırı
      seçenekleri için httpd programının belgelerine
      bakınız.)

    Bu belgede, bir istek aldığında Apache’nin hangi sanal konak
      ile hizmet sunacağına nasıl karar verdiği açıklanmaya çalışılmıştır.
    

    
    Çoğu kullanıcı hangi türü kullanacağına karar vermek için önce İsme dayalı ve IP’ye dayalı Sanal
      Konak bölümünü, sonra İsme Dayalı Sanal
      Konak Desteği veya IP’ye Dayalı Sanal Konak
      Desteği belgesini okumalı ve bazı
      örneklere göz atmalıdır.

    Yapılandırma Dosyası
    

    
    Bu belgede <VirtualHost> bölümleri dışında kalan
      tanımlardan bahsederken ana_sunucu diyeceğiz.
    

    
    <VirtualHost>
      bölümlerindeki tanımlamalardan bahsederken sankonlar
      diyeceğiz.
    

    
    Her VirtualHost bölümü en az bir adres ve isteğe bağlı
      portlar içerir.
    

    
    Sanal konak tanımlarının içindeki IP adreslerinin yerine konak isimleri
      kullanılabilir, fakat bunlar başlatma sırasında çözümleneceklerinden
      çözümlemedeki bir başarısızlık bu sanal konak tanımlarının yoksayılması
      ile sonuçlanacaktır. Bu bakımdan önerilmez.
    

    
    VirtualHost yönergesinde görünen her adresin seçimlik bir
      portu olabilir. Eğer bir port belirtilmemişse, port olarak *
      belirtilmiş gibi bütün portlar dinlenir.
    

    
    (VirtualHost yönergesinde belirtilen port numaraları Apache
      httpd'nin dinleyeceği port numaraları olarak yorumlanmaz, sadece bir
      isteği işleme sokarken hangi VirtualHost bölümünün
      seçileceğini belirlerler. Sunucunun dinleyeceği adresleri ve portları
      belirtmek için Listen
      yönergesini kullanın.)
    

    
    Adreslerin tamamını (DNS sorgularındaki çoklu sonuçlar dahil) içeren
      kümeye sankonların adres kümesi denir.
    

    
    Apache httpd, bir IP adresi ve port birleşimi için en belirgin
      eşleşmelerin listelendiği çok sayıdaki sanal konak arasında ayırdedici
      olarak istemci tarafından sağlanan HTTP Host başlığını
      kullanır.
    

    
    ServerName yönergesi sunucu
      tanımının içinde herhangi bir yerde görünebilirse de her göründüğü yerde
      bir öncekini iptal eder. Hiç ServerName belirtilmemişse,
      Apache httpd, sunucu ismini sunucunun IP adresinden saptamaya
      çalışır.
    

    
    Belli bir IP adresi ve port çifti için yapılandırma dosyasındaki ilk
      isme dayalı sankon önemlidir, çünkü başka hiçbir sankonun ServerName veya
      ServerAlias yönergesi ile eşleşmeyen bu adres ve port çifti için alınmış
      tüm isteklerde bu sankon kullanılır. Ayrıca, sunucunun Sunucu İsmi Belirtimini
      desteklemediği durumlarda tüm SSL bağlantıları için bu sankon
      kullanılır.
    

    
    VirtualHost içindeki isimlerin sırası (jokersiz) bir
      ServerAlias gibi ele alınır (fakat hiçbir
      ServerAlias yönergesi ile geçersiz kılınmaz).
    

    
    Her sankon için bazı değerler öntanımlı olarak atanır. Bunların
      başlıcaları:
    

    
      
      
    1. Sankon bir ServerAdmin
        yönergesi içermiyorsa,
        Timeout,
        KeepAliveTimeout,
        KeepAlive,
        MaxKeepAliveRequests,
        ReceiveBufferSize ve
        SendBufferSize yönergeleri için
        öntanımlı değerler ana_sunucudaki eşdeğerlerinden miras alınır. (Yani,
        bu yönergeler için ana_sunucudaki son değerler miras alınır.)
      2. 

      
    2. Sankon için öntanımlı dizin erişim izinlerinin tanımlandığı "arama
        öntanımlıları" ana_sunucununkilere katılır. Buna her modülün dizinlere
        özgü yapılandırma bilgileri dahildir.
      3. 

      
    3. Her modülün ana_sunucudaki sunuculara özgü yapılandırmaları sankon
        sunucusununkilerle katıştırılır.
      4. 
    
    

    
    Esasen, ana_sunucu, sankon sunucularını oluştururken bir öntanımlılar
      listesi veya öntanımlı değerlere dayanak noktası olarak ele alınır.
      Fakat bu ana_sunucu tanımlarının yapılandırma dosyasındaki yerlerinin
      saptanmasının konumuzla ilgisi yoktur; ana_sunucu yapılandırmasının
      tamamı son katıştırma yapılacağı zaman çözümlenir. Bu bakımdan,
      ana_sunucu tanımlarından bir kısmı sankon tanımlarından sonra yer alsa
      bile sankon tanımlarında etkili olabilir.
    

    
    Eğer, bu noktada ana_sunucu hiçbir ServerName satırı
      içermiyorsa httpd programının çalıştığı makinenin
      konak ismi öntanımlıdır. Ana_sunucunun ServerName için
      yaptığı DNS sorgusundan dönen IP adreslerine ana_sunucu adres
      kümesi diyoruz.
    

    
    Tanımsız ServerName alanları için bir isme dayalı sankon,
      sankonu tanımlayan VirtualHost yönergesinde belirtilen ilk
      adresi öntanımlı değer kabul eder.
    

    
    Sihirli _default_ sankonları için ana_sunucunun
      ServerName değeri kullanılır.

    Sanal Konağın Belirlenmesi
    

    
    Sunucu bir istek durumunda hangi sankonun kullanılacağını şöyle
      belirler:
    

    
    IP adresi aranır
    

    
    Bir adres ve port için bağlantı ilk alındığında Apache httpd tüm
      VirtualHost tanımlarında bu çifti arar.
    

    
    Arama başarısız olursa * (herşey) eşleşmelerine
      bakılır.
    

    
    Bir eşleşme bulunamazsa hizmet ana sunucudan sunulur.
    

    
    Arama sonucunda bu IP adresi için bulunmuş VirtualHost
      tanımları varsa sonraki adım hizmetin bir IP’ye dayalı sankondan mı yoksa
      isme dayalı bir sankondan mı sunulacağına karar vermektir.
    

    

    
    IP’ye dayalı sankon
    

    
    Eğer en iyi eşleşme olarak saptanmış IP adresi ve port çiftini içeren
      sadece bir VirtualHost yönergesi varsa artık karar vermek
      için başka bir şey yapmaya gerek yoktur ve istek bu sankondan
      sunulur.
    

    

    
    İsme dayalı sankon
    

    
    Eğer en iyi eşleşme olarak saptanmış IP adresi ve port çiftini içeren
      birden fazla VirtualHost yönergesi varsa, sonraki
      adımlardaki "liste" eşleşen sankonların listesi olup sankonlar listede
      yapılandırma dosyasındaki yerlerine göre sıralanırlar.
    

    
    Bağlantı SSL kullanıyorsa, sunucunun Sunucu İsmi Belirtimini
      desteklediği durumlarda SSL istemci uzlaşımı, istenen konak ismiyle
      birlikte TLS eklentisini de içeriyorsa, konak ismi, SSL olmayan
      bağlantılardaki Host: başlığı kullanımına benzer şekilde
      aşağıdaki gibi kullanılır. Aksi takdirde, SSL bağlantıları için adresin
      eşleştiği ilk isme dayalı sankon kullanılır. Sunucunun bağlantı için
      hangi sertifikayı kullanacağını sankon belirlediği için bu önemlidir.
    

    
    İstek bir Host: başlık alanı içeriyorsa, listede
      ServerName veya ServerAlias alanı başlık alanı
      ile eşleşen ilk sankona bakılır. Host: alanı bir port
      içerebilirse de Apache httpd bunu yoksayarak daima istemcinin isteği
      gönderdiği portu gerçek port kabul eder.
    

    
    Yapılandırma dosyasındaki belirtilen IP adresiyle eşleşen ilk sankon en
      yüksek önceliğe sahiptir ve sunucu ismi bilinmeyen ve (bir HTTP/1.0
      isteği gibi) Host: başlık alanı içermeyen istekleri de
      yakalar.
    

    

    
    Kalıcı bağlantılar
    

    
    Yukarıda açıklanan IP araması belli bir TCP/IP oturumunda
      bir defaya mahsus yapıldığı halde bir kalıcı/KeepAlive bağlantı
      sırasında her istek için ayrı bir arama yapılır. Başka
      bir deyişle, bir istemci tek bir kalıcı bağlantı üzerinde farklı isme
      dayalı sankonlardan sayfa talebinde bulunabilir.
    

    

    
    Mutlak URI
    

    
    Eğer istekte belirtilen URI bir mutlak URI ise ve istek yapılan konak
      ismi ve port ana sunucuyla veya sankonlardan biriyle eşleşiyorsa,
      şema/konakadı/port öneki ayrılır ve elde edilen göreli URI ilgili
      sankondan veya ana sunucudan sunulur. Eğer bir eşleşme sağlanamazsa
      URI’ye dokunulmaz ve istek bir vekil isteği olarak ele alınır.
    



    İzlenimler
    

    
      
      
    • İsme dayalı sanal konak işlemleri, sunucunun en iyi eşleşen IP'ye
        dayalı sanal konağı seçmesinin ardından uygulanır.
      • 

      
    • İstemcinin hangi IP adresine bağlandığını umursamıyorsanız, sanal
        konaklarınızda adres olarak "*" kullanın, böylece yapılandırılmış
        sankonların hepsine isme dayalı sanal konak işlemleri uygulanır.
      • 

      
    • Bir IP’ye dayalı sankon için asla ServerAlias ve
        ServerPath değerine bakılmaz.
      • 

      
    • Sıralama sadece aynı IP adresine sahip isme dayalı sankonlar arasında
        önemlidir. Aynı adres kümesine mensup isme dayalı sankonlardan
        yapılandırma dosyasında ilk sırada yer alanı en yüksek önceliğe
        sahiptir.
      • 

      
    • Eşleştirme işlemi sırasında Host:
        başlık alanında belirtilen port asla kullanılmaz. Apache httpd daima
        istemcinin isteği gönderdiği gerçek portu kullanır.
      • 

      
    • Eğer aynı IP adresine sahip IP’ye dayalı iki sankon varsa, bunlara
        örtük olarak isme dayalı sanal konak işlemleri uygulanır. 2.3.11
        sürümünden beri yeni davranış şekli budur.
      • 

      
    • Ana_sunucunun bir isteğe hizmet sunabilmesi için istemcinin
        bağlandığı IP adresi ve port hiçbir yerde belirtilmemiş ve
        hiçbir sankon ile eşleşme sağlanamamış olmalıdır. Başka bir deyişle,
        istemcinin bağlandığı port ile eşleşen bir _default_
        sankon olmadıkça adres ve port belirtmeyen bir isteğe ana_sunucu yanıt
        verecektir.
      • 

      
    • VirtualHost yönergelerinde asla DNS isimleri
        belirtmemelisiniz. Aksi takdirde sunucuyu başlatma sırasında DNS
        sorgusu yapmaya zorlamış olursunuz. Listelenen tüm alanlar için DNS
        üzerinde tam denetime sahip değilseniz bu ayrıca bir güvenlik
        tehdidine yol açar. Bu konuda daha ayrıntılı bilgi edinmek için DNS ile ilgili konular ve Apache
        belgesine bakınız.
      • 

      
    • ServerName her sankon için ayrı ayrı belirlenmiş
        olmalıdır. Aksi takdirde her sankon için bir DNS sorgusu gerekir.
      •

    İpuçları
    

    
    DNS konuları sayfasındaki
      ipuçlarına ilaveten burada da bazı ipuçları bulacaksınız:
    

    
      
      
    • Ana sunucu tanımlarının hepsini VirtualHost
        tanımlarının öncesinde bitirin. Bu ayrıca yapılandırmanızın
        okunabilirliğini de arttırır; VirtualHost tanımlarının
        sonrasına sarkan yapılandırmaların katıştırılması işlemi tüm sanal
        konakları etkileyebilen tanımlar bakımından bir
        karışıklığa/belirsizliğe sebep olabilir.)

    What is IP-based virtual hosting
    

    IP-based virtual hosting is a method to apply different directives
based on the IP address and port a request is received on.  Most commonly,
this is used to serve different websites on different ports or interfaces.
    


    In many cases, name-based
virtual hosts are more convenient, because they allow
many virtual hosts to share a single address/port.
See Name-based vs. IP-based
Virtual Hosts to help you decide.  
    

    top
    

    

    System requirements
    

    
    As the term IP-based indicates, the server
    must have a different IP address/port combination for each IP-based
    virtual host. This can be achieved by the machine
    having several physical network connections, or by use of
    virtual interfaces which are supported by most modern operating
    systems (see system documentation for details, these are
    frequently called "ip aliases", and the "ifconfig" command is
    most commonly used to set them up), and/or using multiple
    port numbers.
    

    
     In the terminology of Apache HTTP Server, using a single IP address
    but multiple TCP ports, is also IP-based virtual hosting.

    How to set up Apache
    

    
    There are two ways of configuring apache to support multiple
    hosts. Either by running a separate httpd daemon for
    each hostname, or by running a single daemon which supports all the
    virtual hosts.
    

    
    Use multiple daemons when:
    

    
      
      
    • There are security partitioning issues, such as company1
      does not want anyone at company2 to be able to read their
      data except via the web. In this case you would need two
      daemons, each running with different User, Group, Listen, and ServerRoot settings.
      • 

      
    • You can afford the memory and file descriptor
      requirements of listening to every IP alias on the
      machine. It's only possible to Listen to the "wildcard"
      address, or to specific addresses. So if you have a need to
      listen to a specific address for whatever reason, then you
      will need to listen to all specific addresses. (Although one
      httpd could listen to N-1 of the addresses, and another could
      listen to the remaining address.)
      • 
    
    

    
    Use a single daemon when:
    

    
      
      
    • Sharing of the httpd configuration between virtual hosts
      is acceptable.
      • 

      
    • The machine services a large number of requests, and so
      the performance loss in running separate daemons may be
      significant.
      • 
    
    


    top
    

    

    Setting up multiple daemons
    

    
    Create a separate httpd installation for each
    virtual host. For each installation, use the Listen directive in the
    configuration file to select which IP address (or virtual host)
    that daemon services. e.g.
    

    
    Listen 192.0.2.100:80
    


    
    It is recommended that you use an IP address instead of a
    hostname (see DNS caveats).
    


    top
    

    

    Setting up a single daemon
  with virtual hosts
    

    
    For this case, a single httpd will service
    requests for the main server and all the virtual hosts. The VirtualHost directive
    in the configuration file is used to set the values of ServerAdmin, ServerName, DocumentRoot, ErrorLog and TransferLog
    or CustomLog
    configuration directives to different values for each virtual
    host. e.g.
    

    
    <VirtualHost 172.20.30.40:80>
    ServerAdmin webmaster@www1.example.com
    DocumentRoot "/www/vhosts/www1"
    ServerName www1.example.com
    ErrorLog "/www/logs/www1/error_log"
    CustomLog "/www/logs/www1/access_log" combined
</VirtualHost>

<VirtualHost 172.20.30.50:80>
    ServerAdmin webmaster@www2.example.org
    DocumentRoot "/www/vhosts/www2"
    ServerName www2.example.org
    ErrorLog "/www/logs/www2/error_log"
    CustomLog "/www/logs/www2/access_log" combined
</VirtualHost>
    


    
    It is recommended that you use an IP address instead of a
    hostname in the <VirtualHost> directive
    (see DNS caveats).
    

    
     Specific IP addresses or ports have precedence over their wildcard
    equivalents, and any virtual host that matches has precedence over
    the servers base configuration.
    

    
    Almost any configuration directive can be
    put in the VirtualHost directive, with the exception of
    directives that control process creation and a few other
    directives. To find out if a directive can be used in the
    VirtualHost directive, check the Context using the
    directive index.
    

    
    SuexecUserGroup
    may be used inside a
    VirtualHost directive if the suEXEC
    wrapper is used.
    

    
    SECURITY: When specifying where to write log files,
    be aware of some security risks which are present if anyone
    other than the user that starts Apache has write access to the
    directory where they are written. See the security tips document
    for details.

    Le but de ce document est d'essayer de répondre aux questions 
    les plus répandues sur la configuration des serveurs virtuels. 
    Les scénarios présentés ici se rencontrent quand plusieurs 
    serveurs Webs doivent tourner sur une seule et même machine au 
    moyen de serveurs virtuels par nom 
    ou par IP.
    


    


    top
    

    

    Fonctionnement de plusieurs serveurs 
  virtuels par nom sur une seule adresse IP.
    

    
    Votre serveur possède plusieurs noms d'hôte qui correspondent à une seule
    adresse IP, et vous souhaitez des réponses différentes si on demande
    www.example.com ou www.example.org.
    

    
    Note :
    La configuration de serveurs virtuels 
    sous Apache ne provoque pas leur apparition magique dans la 
    configuration du DNS. Il faut que leurs noms soient 
    définis dans le DNS, et qu'ils y soient résolus sur l'adresse IP 
    du serveur, faute de quoi personne ne pourra visiter votre site Web. 
    Il est possible d'ajouter des entrées dans le fichier 
    hosts pour tests locaux, mais qui ne fonctionneront 
    que sur la machine possédant ces entrées.
    
    
    

    
    # Apache doit écouter sur le port 80
Listen 80
<VirtualHost *:80>
    DocumentRoot "/www/example1"
    ServerName www.example.com
  
    # Autres directives ici
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/www/example2"
    ServerName www.example.org

    # Autres directives ici
</VirtualHost>
    

   

    
    Les astérisques correspondent à toutes les adresses, si bien que 
    le serveur principal ne répondra jamais à aucune requête. Comme le
    serveur virtuel
    ServerName www.example.com se trouve en premier dans le fichier 
    de configuration, il a la plus grande priorité et peut être vu 
    comme serveur par défaut ou primaire ; 
    ce qui signifie que toute requête reçue ne correspondant à aucune 
    des directives ServerName sera servie par ce premier 
    <VirtualHost>.
    

    
    La configuration ci-dessus correspond à ce que l'on souhaite pour
    la plupart des serveurs virtuels à base de nom. Il faudra cependant
    utiliser une configuration différente si vous souhaitez servir un
    contenu différent en fonction de l'adresse IP ou du port.
    

    
    
            
    Note :
    

            
    Vous pouvez remplacer * 
            par une adresse IP du système. Le serveur virtuel concerné
	    ne sera alors sélectionné que pour les requêtes HTTP vers
	    cette adresse IP.
    

           
    En général, il est commode d'utiliser * sur 
           les systèmes dont l'adresse IP n'est pas constante - par 
           exemple, pour des serveurs dont l'adresse IP est attribuée 
           dynamiquement par le FAI, et où le DNS est géré au moyen 
           d'un DNS dynamique quelconque. Comme * signifie 
           n'importe quelle adresse, cette configuration 
           fonctionne sans devoir être modifiée quand l'adresse IP du 
           système est modifiée.
    
    
    

    
    top
    

    

    Serveurs virtuels par nom sur plus 
    d'une seule adresse IP.
    

  	
    
          
    Note :
    Toutes les techniques présentées ici 
          peuvent être étendues à un plus grand nombre d'adresses IP.
    
    
    

    
    Le serveur a deux adresses IP. Sur l'une 
    (172.20.30.40), le serveur "principal" 
    server.example.com doit répondre, et sur l'autre 
    (172.20.30.50), deux serveurs virtuels (ou plus) 
    répondront.
    

    
    Listen 80

# Serveur "principal" sur 172.20.30.40
ServerName server.example.com
DocumentRoot "/www/mainserver"

<VirtualHost 172.20.30.50>
    DocumentRoot "/www/example1"
    ServerName www.example.com
    
    # D'autres directives ici ...
</VirtualHost>

<VirtualHost 172.20.30.50>
    DocumentRoot "/www/example2"
    ServerName www.example.org
    
    # D'autres directives ici ...
</VirtualHost>
    


    
    Toute requête arrivant sur une autre adresse que 
    172.20.30.50 sera servie par le serveur principal. 
    Les requêtes vers 172.20.30.50 avec un nom de serveur 
    inconnu, ou sans en-tête Host:, seront servies par 
    www.example.com.
    

    
    top
    

    

    Servir le même contenu sur des 
    adresses IP différentes (telle qu'une adresse interne et une 
    externe).
    

    
    La machine serveur dispose de deux adresses IP 
    (192.168.1.1 et 172.20.30.40). Cette 
    machine est placée à la fois sur le réseau interne (l'Intranet) 
    et le réseau externe (Internet). Sur Internet, le nom 
    server.example.com pointe vers l'adresse externe 
    (172.20.30.40), mais sur le réseau interne, ce même 
    nom pointe vers l'adresse interne (192.168.1.1).
    

    
    Le serveur peut être configuré pour répondre de la même manière 
    aux requêtes internes et externes, au moyen d'une seule section 
    <VirtualHost>.
    

    
    <VirtualHost 192.168.1.1 172.20.30.40>
    DocumentRoot "/www/server1"
    ServerName server.example.com
    ServerAlias server
</VirtualHost>
    


    
    Ainsi, les requêtes en provenance de chacun des deux réseaux 
    seront servies par le même <VirtualHost>.
    

    
    
          
    Note :
    Sur le réseau interne, il est possible 
          d'utiliser le nom raccourci server au lieu du nom 
          complet server.example.com.
    

          
    Notez également que dans l'exemple précédent, vous pouvez 
          remplacer la liste des adresses IP par des * afin 
          que le serveur réponde de la même manière sur toutes ses 
          adresses.
    
    
    

    
    top
    

    

    Servir différents sites sur différents 
    ports.
    

    
    Vous disposez de plusieurs domaines pointant sur la même adresse 
    IP et vous voulez également servir de multiples ports. L'exemple
    suivant montre que la sélection en fonction du nom intervient après
    la sélection de la meilleure correspondance du point de vue adresse
    IP/port.

Listen 8080

    Utilisation simultanée de 
    Virtual_host et de mod_proxy
    

    
    L'exemple suivant montre comment une machine peut mandater 
    un serveur virtuel fonctionnant sur le serveur d'une autre machine. 
    Dans cet exemple, un serveur virtuel de même nom est configuré sur 
    une machine à l'adresse 192.168.111.2. La directive 
    ProxyPreserveHost On est
    employée pour permette au nom de domaine d'être préservé lors du 
    transfert, au cas où plusieurs noms de domaines cohabitent sur 
    une même machine.
    

    
    <VirtualHost *:*>
    ProxyPreserveHost On
    ProxyPass        "/" "http://192.168.111.2/"
    ProxyPassReverse "/" "http://192.168.111.2/"
    ServerName hostname.example.com
</VirtualHost>
    


    
    top
    

    

    Utilisation de serveurs virtuels 
    _default_
    

    
    Serveurs virtuels 
    _default_ pour tous les ports
    

    
    Exemple de capture de toutes les requêtes émanant 
    d'adresses IP ou de ports non connus, c'est-à-dire, d'un 
    couple adresse/port non traité par aucun autre serveur virtuel.
    

    
    <VirtualHost _default_:*>
    DocumentRoot "/www/default"
</VirtualHost>
    


    
    L'utilisation d'un tel serveur virtuel avec un joker pour le 
    port empêche de manière efficace qu'une requête n'atteigne le 
    serveur principal.
    

    
    Un serveur virtuel par défaut ne servira jamais une requête 
    qui est envoyée vers un couple adresse/port utilisée par un 
    serveur virtuel par nom. Si la requête contient un en-tête 
    Host: inconnu, ou si celui-ci est absent, elle 
    sera toujours servie par le serveur virtuel primaire par nom 
    (celui correspondant à ce couple adresse/port trouvé en premier 
    dans le fichier de configuration).
    

    
    Vous pouvez utiliser une directive 
    AliasMatch ou 
    RewriteRule afin de 
    réécrire une requête pour une unique page d'information (ou pour 
    un script).
    
    

    
    Serveurs virtuels 
    _default_ pour des ports différents
    

    
    La configuration est similaire à l'exemple précédent, mais 
    le serveur écoute sur plusieurs ports et un second serveur virtuel 
    _default_ pour le port 80 est ajouté.
    

    
    <VirtualHost _default_:80>
    DocumentRoot "/www/default80"
    # ...
</VirtualHost>

<VirtualHost _default_:*>
    DocumentRoot "/www/default"
    # ...
</VirtualHost>
    


    
    Le serveur virtuel par défaut défini pour le port 80 (il doit 
    impérativement être placé avant un autre serveur virtuel par 
    défaut traitant tous les ports grâce au joker *) capture toutes 
    les requêtes envoyées sur une adresse IP non spécifiée. Le 
    serveur principal n'est jamais utilisé pour servir une requête.
    
    

    
    Serveurs virtuels 
    _default_ pour un seul port
    

    
    Nous voulons créer un serveur virtuel par défaut seulement 
    pour le port 80.
    

    
    <VirtualHost _default_:80>
    DocumentRoot "/www/default"
...
</VirtualHost>
    


    
    Une requête vers une adresse non spécifiée sur le port 80 
    sera servie par le serveur virtuel par défaut, et toute autre 
    requête vers une adresse et un port non spécifiés sera servie 
    par le serveur principal.
    

    
    L'utilisation du caractère générique * dans la
    déclaration d'un serveur virtuel l'emporte sur
    _default_.

    Migration d'un serveur virtuel 
	par nom en un serveur virtuel par IP
    

    
    Le serveur virtuel par nom avec le nom de domaine 
    www.example.org (de notre exemple 
    par nom) devrait obtenir sa propre adresse IP. Pendant la 
    phase de migration, il est possible d'éviter les problèmes avec 
    les noms de serveurs et autres serveurs mandataires qui mémorisent 
    les vielles adresses IP pour les serveurs virtuels par nom.
    
    La solution est simple, car il suffit d'ajouter la nouvelle 
    adresse IP (172.20.30.50) dans la directive 
    VirtualHost.
    

    
    Listen 80
ServerName www.example.com
DocumentRoot "/www/example1"

<VirtualHost 172.20.30.40 172.20.30.50>
    DocumentRoot "/www/example2"
    ServerName www.example.org
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/www/example3"
    ServerName www.example.net
    ServerAlias *.example.net
    # ...
</VirtualHost>
    


    
    Le serveur virtuel peut maintenant être joint par la nouvelle 
    adresse (comme un serveur virtuel par IP) et par l'ancienne 
    adresse (comme un serveur virtuel par nom).
    

	
    top
    

    

    Utilisation de la directive 
    ServerPath
    

    
    Dans le cas où vous disposez de deux serveurs virtuels par nom, 
    le client doit transmettre un en-tête Host: correct 
    pour déterminer le serveur concerné. Les vieux clients HTTP/1.0 
    n'envoient pas un tel en-tête et Apache n'a aucun indice pour 
    connaître le serveur virtuel devant être joint (il sert la 
    requête à partir d'un serveur virtuel primaire). Dans un soucis 
    de préserver la compatibilité descendante, il suffit de créer 
    un serveur virtuel primaire chargé de retourner une page contenant 
    des liens dont les URLs auront un préfixe identifiant les serveurs 
    virtuels par nom.
    

    
    <VirtualHost 172.20.30.40>
    # serveur virtuel primaire
    DocumentRoot "/www/subdomain"
    RewriteEngine On
    RewriteRule "." "/www/subdomain/index.html"
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/www/subdomain/sub1"
    ServerName www.sub1.domain.tld
    ServerPath "/sub1/"
    RewriteEngine On
    RewriteRule "^(/sub1/.*)" "/www/subdomain$1
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/www/subdomain/sub2"
    ServerName www.sub2.domain.tld
    ServerPath "/sub2/"
    RewriteEngine On
    RewriteRule "^(/sub2/.*)" "/www/subdomain$1"
    # ...
</VirtualHost>
    


    
    À cause de la directive 
    ServerPath, une requête sur 
    une URL http://www.sub1.domain.tld/sub1/ est 
    toujours servie par le serveur sub1-vhost.
    
    Une requête sur une URL http://www.sub1.domain.tld/ n'est 
    servie par le serveur sub1-vhost que si le client envoie un en-tête 
    Host: correct. Si aucun en-tête Host: 
    n'est transmis, le serveur primaire sera utilisé.
    
    
    Notez qu'il y a une singularité : une requête sur 
    http://www.sub2.domain.tld/sub1/ est également servie 
    par le serveur sub1-vhost si le client n'envoie pas d'en-tête 
    Host:.
    
    
    Les directives RewriteRule 
    sont employées pour s'assurer que le client qui envoie un en-tête 
    Host: correct puisse utiliser d'autres variantes d'URLs, 
    c'est-à-dire avec ou sans préfixe d'URL.

Limites des descripteurs de fichiers - Serveur HTTP Apache Version 2.4

    Serveur HTTP Apache Version 2.4

    Limites des descripteurs de fichiers
    

    

    Langues Disponibles:  en  |

 tr 
    

    


    
    Quand de nombreux serveurs virtuels sont créés, Apache peut
    dépasser les limites en descripteurs de fichiers ('file descriptors',
    également appelés gestionnaires de fichiers) si chacun
    des serveurs virtuels utilise ses propres fichiers journaux. Le
    nombre total de descripteurs de fichiers utilisés par Apache est
    d'un par fichier journal, un pour chacune des autres directives
    de fichiers journaux, plus un nombre constant compris entre 10 et 20
    pour son fonctionnement interne. Les systèmes d'exploitation Unix
    limitent le nombre de descripteurs de fichiers utilisables par
    processus ; une valeur courante pour cette limite est de 64, et
    cette valeur peut le plus souvent être augmentée.
    

    
    Apache tente d'accroître cette valeur limite si nécessaire, mais
    sans y parvenir dans les cas suivants :
    

    
      
      
    1. Le système d'exploitation ne permet pas l'utilisation d'appels
      systèmes setrlimit().
      2. 

      
    2. L'appel setrlimit(RLIMIT_NOFILE) ne fonctionne pas
      sur votre système d'exploitation (c'est le cas sous Solaris 2.3).
      3. 

      
    3. Le nombre de descripteurs de fichiers nécessaires à Apache
      dépasse la limite physique du matériel.
      4. 

      
    4. Le système impose d'autres limites sur l'utilisation des
      descripteurs de fichiers, comme par exemple une limite sur les
      flux stdio, utilisables uniquement sur les descripteurs de
      fichiers inférieurs à 256. (sous Solaris 2).
      5. 
    
    

    
    En cas de problème, Vous pouvez :
    

    
      
      
    • Réduire le nombre de fichiers journaux, en ne spécifiant
      aucun fichier journal dans les sections
      <VirtualHost>,
      en donc en envoyant les informations aux fichiers journaux du
      serveur principal (Voir Éclatement des
      fichiers journaux ci-dessous pour plus d'informations sur
      cette possibilité).
      • 

      
    • 
        Dans les cas 1 ou 2 (évoqués ci-dessus), augmentez la limite sur
        les descripteurs de fichiers avant le démarrage d'Apache, au
        moyen d'un script comme

        
      
          #!/bin/sh
      
           ulimit -S -n 100
      
           exec httpd      
        
      
      
      • 
    
    




    

    top
    

    

    Éclatement des fichiers journaux
    


    Lorsque vous choisissez d'enregistrer les informations émanant de
plusieurs serveurs virtuels dans un même fichier journal, vous voudrez
ensuite pouvoir scinder ces informations à des fins de statistiques, par
exemple, sur les différents serveurs virtuels. Il est possible de procéder
de la manière suivante :
    


    Tout d'abord, vous devez ajouter le nom du serveur virtuel à chaque
entrée du journal. Ceci se paramètre au moyen de la directive
 LogFormat et de la
variable %v. Ajoutez cette variable au début de la chaîne
de définition du format de journalisations :
    


    LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost
CustomLog logs/multiple_vhost_log vhost
    



    Cette configuration va provoquer la création d'un fichier de
journalisation au format standard (CLF : 'Common Log Format'), mais dont
chaque ligne débutera par le nom canonique du serveur virtuel (spécifié
par la directive ServerName).
(Voir mod_log_config pour d'autres informations sur la
personnalisation des fichiers journaux.)
    


    Au moment de séparer les informations du fichier journal en un fichier
par serveur virtuel, le programme 
split-logfile peut être
utilisé. Ce programme peut être trouvé dans le répertoire
support de la distribution d'Apache.
    


    Exécutez ce programme au moyen de la commande :
    


    
split-logfile < /logs/multiple_vhost_log

    


    Une fois exécuté avec le nom du fichier contenant tous les journaux,
ce programme va générer un fichier pour chacun des serveurs virtuels
qui apparaît dans le fichier d'entrée. Chaque fichier en sortie est
nommé nomduserveur.log.

    Ce document décrit quand et comment utiliser des serveurs
    virtuels par nom.
    

    


    top
    

    

    Serveurs virtuels par nom vs. par IP
    

    
    Les serveurs virtuels par IP utilisent l'adresse IP
    de la connexion afin de déterminer quel serveur virtuel doit
    répondre. Par conséquent, vous devez disposer d'adresses IP
    différentes pour chaque serveur.
    

    
    Avec un hébergement
    virtuel par nom, le serveur s'appuie sur les informations
    transmises par le client dans les en-têtes HTTP de ses requêtes.
    La technique présentée ici vous permet de disposer de serveurs
    virtuels différents partagés sur une même adresse IP.
    

    
    L'hébergement virtuel par nom est habituellement plus simple,
    car il vous suffit de configurer votre serveur DNS pour que
    chaque domaine pointe sur l'adresse IP dont vous disposez, et de
    configurer votre serveur Apache HTTP afin qu'il reconnaisse
    ces domaines. Il réduit aussi la pénurie en adresses IP. Par
    conséquent, vous devriez utiliser l'hébergement virtuel par
    nom, sauf dans le cas où vous utiliseriez des équipements qui
    nécessitent un hébergement basé sur IP. Les raisons historiques de
    l'hébergement basé sur IP dans un but de support de certains clients ne
    s'appliquent plus à un serveur web d'usage général.
    

    
    La sélection du serveur virtuel en fonction du nom s'opère en
    dehors de l'algorithme de sélection du serveur virtuel en fonction
    de l'adresse IP, ce qui signifie que les recherches du point de vue
    du nom du serveur ne s'effectuent que parmi le jeu de serveurs
    virtuels pour lesquels la correspondance avec la paire adresse
    IP/port est la plus exacte.
    


    top
    

    

    Comment le serveur sélectionne-t-il le serveur
virtuel basé sur le nom approprié
    

    
    Il est important de savoir que la première étape de la résolution
    de serveur virtuel basée sur le nom est une résolution basée sur IP.
    La résolution de serveur virtuel basée sur le nom ne fait que
    choisir le serveur virtuel basé sur le nom le plus approprié, en se
    limitant aux candidats qui conviennent le mieux du point de vue IP.
    La résolution basée sur IP est sans objet si l'on
    utilise un caractère générique (*) pour l'adresse IP dans
    toutes les directives VirtualHost.
    

    
    A l'arrivée d'une requête, le serveur va rechercher l'argument de
    section <VirtualHost> présentant la meilleure
    (la plus exacte) correspondance avec la paire adresse IP/port
    utilisée dans la requête. Si plusieurs serveurs virtuels possèdent
    cette même paire adresse IP/port, Apache va ensuite comparer les
    valeurs des directives ServerName et ServerAlias avec le nom de serveur
    présent dans la requête.
    

    
    Si vous ne définissez pas de directive ServerName pour un serveur virtuel à base
    de nom, le serveur utilisera par défaut le nom de domaine
    entièrement qualifié (FQDN) déduit du nom d'hôte système. Cette
    configuration sans nom de serveur explicite peut conduire à des
    erreurs de choix du serveur virtuel à utiliser et est déconseillée.
    

    
    Le serveur virtuel à base de nom
    par défaut pour une paire adresse IP/port
    
    
    Si aucune directive ServerName ou ServerAlias ne correspond dans
    la liste de serveurs virtuels présentant la meilleure correspondance
    du point de vue adresse IP/port, c'est le premier serveur
    virtuel de cette liste qui sera utilisé.

    Utilisation de serveurs virtuels par nom
    


    Modules ApparentésDirectives Apparentées
    


    
    La première étape consiste à créer une section
    <VirtualHost>
    pour chacun des serveurs à définir. Dans chaque section
    <VirtualHost>,
    vous devez définir au minimum une directive
    ServerName pour désigner
    le serveur concerné et une directive
    DocumentRoot pour préciser
    l'emplacement sur le système de fichiers du contenu de ce serveur.
    

    
    Le serveur principal disparaît
    
        
    Toute requête qui ne correspond à aucune section <VirtualHost> existante
	est traitée avec la configuration du serveur principal, sans
	tenir compte du nom d'hôte ou de la directive ServerName.
    

        
    Lorsque vous ajoutez un serveur virtuel basé sur le nom à un
	serveur existant, et si les caractéristiques de ce serveur
	virtuel correspondent à des combinaisons IP/port préexistantes,
	les requêtes seront alors traitées par un serveur virtuel
	explicite. Dans ce cas, il est en général judicieux de créer un
	serveur virtuel par défaut
	comportant une directive ServerName correspondant au nom du
	serveur principal. De nouveaux domaines sur les mêmes interface
	et port, mais nécessitant des configurations distinctes,
	pourront alors être ajoutés en tant que serveurs virtuels
	spécifiques (et non par défaut).
    
    
    

    
    Héritage du nom de serveur
    
       
    Il est toujours préférable de définir une directive ServerName au niveau de chaque serveur
       virtuel à base de nom. Si un serveur virtuel ne définit pas
       de directive  ServerName, le
       nom de ce serveur virtuel sera hérité du serveur principal. Si
       aucun nom de serveur n'a été explicitement défini au niveau du
       serveur principal, le serveur tentera de déterminer son nom via
       une résolution de nom DNS inverse sur la première adresse
       d'écoute. Dans tous les cas, ce nom de serveur hérité influencera
       la sélection du serveur virtuel à base de nom, c'est pourquoi il
       est toujours préférable de définir une directive ServerName pour chaque serveur virtuel
       à base de nom.
    
    
    

    
    Par exemple, supposez que vous hébergez le domaine
    www.example.com et que vous souhaitez ajouter le
    serveur virtuel other.example.com qui pointe sur
    la même adresse IP. Il vous suffit d'ajouter la configuration
    suivante à httpd.conf :
    

    
    <VirtualHost *:80>
    # Le premier serveur virtuel de la liste est aussi le
    # serveur par défaut pour *:80
    ServerName www.example.com
    ServerAlias example.com
    DocumentRoot "/www/domain"
</VirtualHost>

<VirtualHost *:80>
    ServerName other.example.com
    DocumentRoot "/www/otherdomain"
</VirtualHost>
    


    
    Autrement, vous pouvez spécifiez une adresse IP explicite
    à la place de * dans la directive
    <VirtualHost>.
    Par exemple, cette méthode est utile si vous souhaitez faire
    tourner quelques serveurs virtuels par nom sur une même adresse
    IP, et d'autres, soit par IP, soit basés sur un autre jeu de
    serveurs virtuels par nom sur une autre adresse IP.
    

    
    Plusieurs serveurs sont accessibles par plus d'un nom. Il
    suffit de placer la directive
    ServerAlias dans une section
    <VirtualHost>.
    Par exemple, dans la première section
    <VirtualHost>
    ci-dessus, la directive ServerAlias
    indique aux utilisateurs les autres noms permis pour accéder au
    même site Web :
    

    
    ServerAlias example.com *.example.com
    


    
    ainsi, toutes les requêtes portant sur un domaine
    example.com seront servies par le serveur virtuel
    www.example.com. Les caractères joker *
    et ? peuvent être utilisés pour les correspondances.
    Bien entendu, vous ne pouvez pas inventer des noms et les placer
    dans une directive ServerName
    ou ServerAlias. Tout d'abord, votre serveur DNS
    doit être correctement configuré pour lier ces noms à une
    adresse IP associée avec votre serveur.
    

    
    La recherche du serveur virtuel à base de nom qui correspond au
    plus près à la requête s'effectue parmi les <virtualhost> selon leur
    ordre d'apparition dans le fichier de configuration. Le premier
    serveur virtuel dont le ServerName ou le ServerAlias correspond est utilisé, sans
    priorité particulière en cas de présence de caractères génériques
    (que ce soit pour le ServerName ou le ServerAlias).
    

    
    La liste complète des noms dans la section VirtualHost sont traités comme une
    directive ServerAlias sans
    caractères génériques.
    

    
    Finalement, vous pouvez affiner la configuration des serveurs
    virtuels en plaçant d'autres directives à l'intérieur des sections
    <VirtualHost>.
    La plupart des directives peut être placée dans ces sections en
    y changeant seulement la configuration du serveur virtuel associé.
    Pour déterminer si une directive particulière est permise,
    consultez le contexte de la
    directive. Le jeu de directives configurées dans le contexte
    du serveur principal (en dehors de toutes sections
    <VirtualHost>)
    sera utilisé seulement s'il n'y a pas de configuration contraire
    par un serveur virtuel.

    This document describes when and how to use name-based virtual hosts.
    

    


    top
    

    

    Name-based vs. IP-based Virtual Hosts
    

    
    IP-based virtual hosts use the IP address of the connection to
    determine the correct virtual host to serve.  Therefore you need to
    have a separate IP address for each host.
    

    
    With name-based virtual hosting, the server relies on the client to
    report the hostname as part of the HTTP headers.  Using this technique,
    many different hosts can share the same IP address.
    

    
    Name-based virtual hosting is usually simpler, since you need
    only configure your DNS server to map each hostname to the correct
    IP address and then configure the Apache HTTP Server to recognize
    the different hostnames. Name-based virtual hosting also eases
    the demand for scarce IP addresses. Therefore you should use
    name-based virtual hosting unless you are using equipment
    that explicitly demands IP-based hosting.  Historical reasons for
    IP-based virtual hosting based on client support are no longer
    applicable to a general-purpose web server.
    

    
     Name-based virtual hosting builds off of the IP-based virtual host
    selection algorithm, meaning that searches for the proper server name
    occur only between virtual hosts that have the best IP-based address.
    


    top
    

    

    How the server selects the proper name-based virtual host
    

    
    It is important to recognize that the first step in name-based virtual
    host resolution is IP-based resolution.  Name-based virtual host
    resolution only chooses the most appropriate name-based virtual host
    after narrowing down the candidates to the best IP-based match.  Using a wildcard (*)
    for the IP address in all of the VirtualHost directives makes this
    IP-based mapping irrelevant.
    

    
    When a request arrives, the server will find the best (most specific) matching
    <VirtualHost> argument based on
    the IP address and port used by the request.  If there is more than one virtual host
    containing this best-match address and port combination, Apache will further
    compare the ServerName and ServerAlias directives to the server name
    present in the request.
    

    
    If you omit the ServerName 
    directive from any name-based virtual host, the server will default
    to a fully qualified domain name (FQDN) derived from the system hostname.
    This implicitly set server name can lead to counter-intuitive virtual host
    matching and is discouraged.
    
 
    
    The default name-based vhost for an IP and port combination 
    
    
     If no matching ServerName or ServerAlias is found in the set of
    virtual hosts containing the most specific matching IP address and port
    combination, then the first listed virtual host that
    matches that will be used.
    

    top
    

    

    Using Name-based Virtual Hosts
    


    Related ModulesRelated Directives
    

    
    The first step is to create a <VirtualHost> block for
    each different host that you would like to serve.  Inside each <VirtualHost> block, you will need at minimum a
    ServerName directive to designate
    which host is served and a DocumentRoot
    directive to show where in the filesystem the content for that host
    lives.
    

    
    Main host goes away
    
        
     Any request that doesn't match an existing <VirtualHost> is handled by the global
        server configuration, regardless of the hostname or ServerName.
    

        
     When you add a name-based virtual host to an existing server, and
        the virtual host arguments match preexisting IP and port combinations,
        requests will now be handled by an explicit virtual host.  In this case,
        it's usually wise to create a default virtual host
        with a ServerName matching that of
        the base server.  New domains on the same interface and port, but
        requiring separate configurations,  can then be added as subsequent (non-default)
        virtual hosts.
    
    
    

    
    ServerName inheritance
    
       
     It is best to always explicitly list a  ServerName in every name-based virtual host.
    
       
    If a VirtualHost doesn't specify 
       a ServerName, a server name will be 
       inherited from the base server configuration.  If no server name was 
       specified globally, one is detected at startup through reverse DNS resolution
       of the first listening address.  In either case, this inherited server name
       will influence name-based virtual host resolution, so it is best to always
       explicitly list a  ServerName in every
       name-based virtual host.
    
    
    

    
    For example, suppose that you are serving the domain
    www.example.com and you wish to add the virtual host
    other.example.com, which points at the same IP address.
    Then you simply add the following to httpd.conf:
    

    
    <VirtualHost *:80>
    # This first-listed virtual host is also the default for *:80
    ServerName www.example.com
    ServerAlias example.com 
    DocumentRoot "/www/domain"
</VirtualHost>

<VirtualHost *:80>
    ServerName other.example.com
    DocumentRoot "/www/otherdomain"
</VirtualHost>
    


    
    You can alternatively specify an explicit IP address in place of the
    * in <VirtualHost> directives. For example, you might want to do this
    in order to run some name-based virtual hosts on one IP address, and either
    IP-based, or another set of name-based virtual hosts on another address.
    

    
    Many servers want to be accessible by more than one name. This is
    possible with the ServerAlias
    directive, placed inside the <VirtualHost> section. For example in the first <VirtualHost> block above, the
    ServerAlias directive indicates that
    the listed names are other names which people can use to see that same
    web site:
    

    
    ServerAlias example.com *.example.com
    


    
    then requests for all hosts in the example.com domain will
    be served by the www.example.com virtual host. The wildcard
    characters * and ? can be used to match names.
    Of course, you can't just make up names and place them in ServerName or ServerAlias. You must
    first have your DNS server properly configured to map those names to an IP
    address associated with your server.
    

    
    Name-based virtual hosts for the best-matching set of  <virtualhost>s are processed 
    in the order they appear in the configuration.  The first matching ServerName or ServerAlias is used, with no different precedence for wildcards
    (nor for ServerName vs. ServerAlias).  
    

    
    The complete list of names in the VirtualHost
    directive are treated just like a (non wildcard) 
    ServerAlias.
    

    
    Finally, you can fine-tune the configuration of the virtual hosts
    by placing other directives inside the <VirtualHost> containers. Most directives can be
    placed in these containers and will then change the configuration only of
    the relevant virtual host. To find out if a particular directive is allowed,
    check the Context of the
    directive. Configuration directives set in the main server context
    (outside any <VirtualHost>
    container) will be used only if they are not overridden by the virtual host
    settings.

    Bu belgede sanal konakların sonu belirsiz bir şekilde artışı karşısında
      Apache HTTP Sunucusunun nasıl daha verimli kullanılacağı açıklanmıştır.
      Devingen kitlesel konakları oluşturmak için mod_rewrite
      modülünün kullanımını açıklayan ayrı bir
      belge de mevcuttur.

    Amaç
    

    
    Burada açıklanan teknikler, httpd.conf dosyanızın
      örnekteki gibi, aslında hemen hemen birbirinin aynı çok sayıda
      <VirtualHost> bölümü içereceği zaman yapılacaklar ile
      ilgilidir.
    


    <VirtualHost 111.22.33.44>
    ServerName                 musteri-1.example.com
    DocumentRoot        "/siteler/musteri-1/belgeler"
    ScriptAlias  "/cgi-bin/"  "/siteler/musteri-1/cgi-bin"
</VirtualHost>

<VirtualHost 111.22.33.44>
    ServerName                 musteri-2.example.com
    DocumentRoot        "/siteler/musteri-2/belgeler"
    ScriptAlias   "/cgi-bin/"   "/siteler/musteri-2/cgi-bin"
</VirtualHost>

<VirtualHost 111.22.33.44>
    ServerName                 musteri-N.example.com
    DocumentRoot          "/siteler/musteri-N/belgeler"
    ScriptAlias   "/cgi-bin/"  "/siteler/musteri-N/cgi-bin"
</VirtualHost>
    


    
    İsteğimiz çok sayıda <VirtualHost> bölümünü devingen
      olarak çalışan tek bir <VirtualHost> bölümüyle
      değiştirmektir. Bunun elbette bazı getirileri olacaktır:
    

    
      
      
    1. Yapılandırma dosyanız küçüleceği için Apache daha çabuk
        başlatılabilecek ve daha az bellek harcayacaktır. Muhtemelen daha da
        önemlisi, küçülmüş bir yapılandırmanın bakımı da kolaylaşacağı için
        hatalar da azalacaktır.
      2. 

      
    2. Yeni sanal konakların eklenmesi, DNS’de yeni girdiler oluşturmak ve
        dosya sisteminde bununla ilgili dizinleri açmak dışında biraz daha
        basit olacaktır; en azından Apache’yi yeniden yapılandırmak ve yeniden
        başlatmak zorunda kalmayacaksınız.
      3. 
    
    

    
    Ana götürüsü ise her sanal konak için ayrı birer günlük dosyasına sahip
      olamayacak olmanızdır. Öte yandan, dosya
      tanıtıcılarının sınırlı olması  nedeniyle bunu yapmayı zaten
      istemezsiniz. Günlük kayıtları için bir fifo
      veya bir boru hattı oluşturmak ve diğer uçta çalışan bir süreç
      vasıtasıyla günlükleri müşterilere paylaştırmak daha iyidir. Böyle bir
      işlemle ilgili bir örneği split-logfile aracının belgesinde bulabilirsiniz.

    Genel Bakış
    

    
    Bir sanal konak iki bilgiye bakarak belirlenir: IP adresi ve HTTP
      isteğindeki Host: başlığının içeriği. Devingen sanal
      barındırma tekniği, isteği yerine getirmek için kullanılacak dosya
      yoluna bu bilgiyi kendiliğinden girmek esasına dayanır. Bu, Apache httpd
      ile mod_vhost_alias modülünü kullanarak oldukça kolay
      yapılabileceği gibi mod_rewrite modülü
      de kullanılabilir.
    

    
    Bu modüllerin her ikisi de öntanımlı olarak devre dışıdır. Bu tekniği
      kullanmak isterseniz  Apache httpd'yi yeniden yapılandırıp derleyerek bu
      iki modülü etkin duruma getirmeniz gerekir.
    

    
    Devingen sanal konağı normal bir sanal konak gibi göstermek için
      bazı bilgileri istekten saptamak gerekir. Bunlardan en önemlisi,
      httpd tarafından göreli URL’lerden normal URL’leri ve benzerlerini
      üretmek için kullanılan sunucu ismidir. Sunucu ismi
      ServerName yönergesi ile yapılandırılır ve CGI’ler
      tarafından SERVER_NAME ortam değişkeni üzerinden
      kullanılır. Çalışma anındaki asıl değer UseCanonicalName yönergesi tarafından denetlenir.
      UseCanonicalName Off olduğunda sunucu ismi isteğin
      Host: başlık alanından elde edilir. UseCanonicalName
      DNS belirtilmişse, sunucu ismi, sanal konağın IP adresinden
      tersine DNS sorgusu yapılarak elde edilir. Birincisi isme dayalı sanal
      konaklar tarafından ikincisi ise IP’ye dayalı sanal konaklar tarafından
      kullanılır. Eğer httpd, istekte Host: başlığının olmayışı
      veya DNS sorgusunun başarısız olması sebebiyle sunucu ismini elde
      edemezse son çare olarak ServerName yönergesinde yazılı
      değeri kullanır.
    

    
    Saptanan bilgilerden biri de DocumentRoot
      yönergesi ile yapılandırılan belge kök dizini olup CGI’ler tarafından
      DOCUMENT_ROOT ortam değişkeni üzerinden kullanılır. Normal
      yapılandırmada core modülü tarafından dosya isimlerini
      URI’lere eşlerken kullanılır. Fakat sunucu devingen sanal konakları
      kullanmak üzere yapılandırıldığında, eşleştirmeyi farklı yollardan yapan
      başka bir modül devreye girer (mod_vhost_alias veya
      mod_rewrite). DOCUMENT_ROOT ortam
      değişkenine değerini atamaktan sorumlu olan bu iki modülden biri
      kullanılmazsa CGI veya SSI belgeleri yanlış değerlerle üretilirler.

    mod_vhost_alias ile Kitlesel Sanal Konaklar
    

    
    Yukarıda Amaç bölümünde özetlenen sanal konak
      düzenlemesinin mod_vhost_alias kullanarak gerçekleştirilmiş
      halini içeren httpd.conf bölümü aşağıdadır.
    


    # sunucu ismini Host: başlığından elde edelim
UseCanonicalName Off

# Bu günlükleme biçiminde split-logfile aracı kullanılarak
# sanal konak günlükleri ilk alana göre ayrıştırılabilir
LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log vcommon"

# istekleri yerine getirmek için kullanılacak
# dosya isimlerine sunucu ismini ekleyelim
VirtualDocumentRoot "/siteler/%0/belgeler"
VirtualScriptAlias  "/siteler/%0/cgi-bin"
    


    
    Bu yapılandırmayı IP’ye dayalı sanal konaklar için kullanmak isterseniz
      UseCanonicalName Off yerine UseCanonicalName
      DNS yazmanız yeterlidir. Böylece dosya ismine eklenecek konak
      ismi sanal konağın IP adresinden türetilir. %0 değişkeni,
      Host: başlığı ile belirlenen istekteki sunucu isminin
      ifadesidir.
    

    
    Kullanım örnekleri için mod_vhost_aliasmodülünün
      belgesine bakınız.

    Basitleştirilmiş Kitlesel Sanal Konaklar
    

    
    Bu sistem, yukarıdaki yapılandırmanın bir ISS’nin sunucusuna
      uyarlanmasından başka bir şey değildir. %2 değişkenini
      kullanarak, dosya isminde kullanmak üzere sunucu isminin alt dizgelerini
      seçebiliriz, böylece, örneğin www.user.example.com belgeleri
      /home/user/www dizininde bulunabilir. Farklı olarak her
      sanal konak için bir tane değil hepsi için bir tane cgi-bin
      olacaktır.
    

    
    UseCanonicalName Off

LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# sunucu ismini içerecek dosya isimlerini oluşturalım
VirtualDocumentRoot "/home/%2/www"

# ortak cgi-bin dizini
ScriptAlias  "/cgi-bin/"  "/siteler/std-cgi/"

      VirtualDocumentRoot örnekleri vardır.

    Aynı Sunucuda Kişisel ve Kurumsal Sanal Konaklar
    

    
    Daha karmaşık ayarlamalar yaparak httpd’nin normal
      <VirtualHost> bölümlerini farklı kitlesel sanal konak
      yapılandırmaları için kullanabilirsiniz. Örneğin, bireysel
      müşterileriniz için bir IP adresiniz, kurumsal müşterileriniz için de
      başka bir IP adresiniz olsun. Her biri için ayrı ayrı sanal konaklar
      ayarlamak yerine aşağıdaki gibi bir yapılandırma kullanabilirsiniz:
    


    UseCanonicalName Off

LogFormat "%V %h %l %u %t \"%r\" %s %b" vcommon

<Directory "/siteler/kurumsal">
    Options FollowSymLinks
    AllowOverride All
</Directory>

<Directory "/siteler/bireysel">
    Options FollowSymLinks
    AllowOverride None
</Directory>

<VirtualHost 111.22.33.44>
    ServerName kurumsal.example.com

    CustomLog "logs/access_log.kurumsal" vcommon

    VirtualDocumentRoot "/siteler/kurumsal/%0/belgeler"

    Bilginize
    
      
    Eğer ilk <VirtualHost> bölümü bir ServerName yönergesi içermezse ilgili IP
        için ters DNS sorgusu yapılır. Eğer sorgudan elde edilen isim
        sunucunun ismi değilse bu istenmeyen duruma bir çözüm olarak bir
        bilgilendirme bölümü (örn, ServerName bilgi.example.com)
        eklenebilir.

    IP’ye dayalı sanal konakları daha verimli kılmak
    
    

    
    İlk örnekte IP’ye dayalı sanal konaklar için
      kullanılmak istenirse yapılandırmada neyin nasıl değiştirileceği
      belirtilmişti. Her istek için ayrı bir DNS sorgusu gerekeceğinden bu
      başarım düşmesine yol açar. DNS sorgusu ihtiyacını ortadan kaldırmak
      için, bir çözüm olarak dosya sistemi, konak isimleri yerine IP
      adreslerine göre düzenlenebilir. Günlük kayıtları da IP adreslerine göre
      ayrıştırılacak şekilde ayarlanabilir.
    


    # Sunucu ismini IP adresinden ters DNS sorgusu ile elde edelim
UseCanonicalName DNS

# Günlük kayıtları IP adreslerine göre ayrıştırılabilsin
LogFormat "%A %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

# dosya isimleri IP adreslerini içersin
VirtualDocumentRootIP "/siteler/%0/belgeler"
VirtualScriptAliasIP  "/siteler/%0/cgi-bin"

    mod_rewrite ile Kitlesel Sanal Konaklar
    
    

    
    Kitlesel sanal barındırma mod_rewrite modülü kullanarak
      da gerçeklenebilir. Ya basitçe RewriteRule yönergelerini kullanırsınız ya da daha karmaşık
      olarak sanal konak tanımlarınızı harici bir yerde tutar ve bunlara
      RewriteMap yönergesini
      kullanarak erişirsiniz. Bu teknikler ayrıntılı olarak
      rewrite belgelerinde
      açıklanmıştır.

    mod_macro ile Kitlesel Sanal Konaklar
    
    

    
    Devingen olarak üretilen sanal konaklar için diğer bir seçenek 
      mod_macro modülüdür. Bir sanal konak şablonu oluşturup 
      bunu çok sayıda konak ismi için çağırabilirsiniz. Modül belgelerinin 
      Kullanım bölümünde böyle bir örneğe yer verilmiştir.

    IP'ye dayalı sanal konak desteği nedir
    
    
    IP'ye dayalı sanal konak desteği, bir isteğin alındığı IP adresi ve
      porta bağlı olarak farklı yönergeleri uygulamak için bir yoldur. Özetle,
      farklı siteleri farklı portlardan ve arayüzlerden sunmakta
      kullanılır.
    

     
    Çoğu durumda, isme dayalı sanal konaklar
       birçok sanal konağın tek bir IP adresi/port çiftini paylaşmasını
       sağladığından daha kullanışlıdır. Neyi kullanacağınıza karar vermek için
       İsme dayalı ve IP’ye dayalı Sanal
       Konaklar bölümüne bakınız.

    Sistem gereksinimleri
    

    
    IP’ye dayalı deyince, sunucunun her IP’ye dayalı
      sanal konak için ayrı bir IP adresi/port çiftine sahip olduğunu
      anlıyoruz. Bunun olması için, makine ya çok sayıda ağ bağlantısına
      sahiptir ya da makinede, günümüzde çoğu işletim sistemi tarafından
      desteklenen sanal arabirimler ve/veya çok sayıda port kullanılıyordur.
      (Sanal arabirimlerle ilgili ayrıntılar için sistem belgelerinize bakınız;
      bu konu genellikle IP rumuzları (ip aliases) olarak geçer ve ayarlamak
      için genellikle "ifconfig" komutu kullanılır.)
    

    
    Apache HTTP Sunucusu terminolojisinde, tek bir IP adresinin çok sayıda
      TCP portuyla kullanımı IP'ye dayalı sanal konak desteği olarak
      bilinir.

    Apache nasıl ayarlanır?
    

    
    Çok sayıda konağı desteklemek üzere Apache iki şekilde
      yapılandırılabilir. Ya her konak için ayrı bir httpd
      süreci çalıştırırsınız ya da tüm sanal konakları destekleyen tek bir
      süreciniz olur.
    

    
    Çok sayıda süreç kullanıyorsanız:
    

    
      
      
    • Güvenli bölgeler oluşturmanız gerekiyordur. Örneğin, şirket2’deki hiç
        kimse dosya sistemi üzerinden şirket1’e ait verileri okuyamasın, sadece
        herkes gibi tarayıcı kullanarak okuyabilsin istenebilir.  Bu durumda,
        User,
        Group,
        Listen ve
        ServerRoot yönergeleri farklı
        değerlerle yapılandırılmış iki ayrı süreç çalıştırmanız gerekir.
      • 

      
    • Makine üzerindeki her IP adresini dinlemek için gereken dosya tanıtıcı
        ve bellek miktarını makul bir seviyede tutabilirsiniz. Bu sadece belli
        adresleri dinleyerek veya çok sayıda adresle eşleşen adres kalıpları
        kullanarak mümükün olabilir. Zaten, bir sebeple belli bir adresi dinleme
        ihtiyacı duyarsanız, diğer tüm adresleri de ayrı ayrı dinlemeniz
        gerekir. (Bir httpd programı N-1 adresi dinlerken
        diğerleri kalan adresleri dinleyebilir.)
      • 
    
    

    
    Tek bir süreç kullanıyorsanız:
    

    
      
      
    • httpd yapılandırmasının sanal konaklar arasında
        paylaşılmasına izin veriliyor demektir.
      • 

      
    • Makine çok büyük miktarda isteği karşılayabilir ve ayrı ayrı
        süreçlerin çalışmasından kaynaklanan önemli başarım kayıpları
        yaşanmaz.
      •

    Çok sayıda sürecin yapılandırılması
    

    
    Her sanal konak için ayrı bir httpd yapılandırması
      oluşturulur. Her yapılandırmada, o süreç tarafından sunulacak IP adresi
      (veya sanal konak) için Listen
      yönergesi kullanılır. Örnek:
    

    
    Listen 192.0.2.100:80
    


    
    Burada konak ismi yerine IP adresi kullanmanız önerilir (ayrıntılar için
      DNS ile ilgili konular belgesine
      bakınız).
    


    top
    

    

    Sanal konaklar tek bir sürecin yapılandırılması
    

    
    Bu durum için, ana sunucu ve sanal konakların tümüne gelen istekler tek
      bir httpd süreci tarafından karşılanır. Yapılandırma
      dosyasında, her sanal konak için, farklı değerlere sahip ServerAdmin, ServerName, DocumentRoot, ErrorLogveTransferLog
      veya CustomLog yönergeleri
      içeren ayrı birer VirtualHost bölümü
      oluşturulur. Örnek:
    

    
    <VirtualHost 192.168.1.10:80>
    ServerAdmin bilgi@example.com
    DocumentRoot "/siteler/belgeler/ecom"
    ServerName example.com
    ErrorLog "/siteler/gunlukler/ecom/hatalar.log"
    CustomLog "/siteler/gunlukler/ecom/erisim.log" combined
</VirtualHost>

<VirtualHost 192.168.1.20:80>
    ServerAdmin bilgi@example.org
    DocumentRoot "/siteler/belgeler/eorg"
    ServerName example.org
    ErrorLog "/siteler/gunlukler/eorg/hatalar.log"
    CustomLog "/siteler/gunlukler/eorg/erisim.log" combined
</VirtualHost>
    


    
    <VirtualHost> yönergesinde konak ismi yerine
       IP adresi kullanmanız önerilir (ayrıntılar için
       DNS ile ilgili konular
       belgesine bakınız).
    

    
    Belli bir IP adresi veya port kullanımı bunların joker eşdeğerlerine
      göre daha yüksek öncelik sağlar ve eşleşen bir sanal konak da genel
      sunucuya göre öncelik alır.
    

    
    Süreç oluşturmayı denetleyen yönergeler ve bir kaç başka yönerge dışında
      hemen hemen tüm yapılandırma yönergeleri VirtualHost bölümleri içinde kullanılabilir.
      Bir yönergenin VirtualHost
      bölümlerinde kullanılıp kullanılmayacağını öğrenmek için yönerge dizinini kullanarak yönergenin
      Bağlam’ına bakınız.
    

    
    suEXEC sarmalayıcısı kullanıldığı takdirde
      SuexecUserGroup yönergesi de
      bir VirtualHost bölümü içinde
      kullanılabilir.
    

    
    GÜVENLİK:Günlük dosyalarının yazılacağı yeri belirlerken,
      Apache’yi başlatan kullanıcıdan başka kimsenin yazamayacağı bir yerin
      seçilmesi bazı güvenlik risklerini ortadan kaldırmak bakımından
      önemlidir. Ayrıntılar için güvenlik
      ipuçları belgesine bakınız.

    This document attempts to explain
    exactly what Apache HTTP Server does when deciding what virtual host to
    serve a request from.
    

    
    Most users should read about 
    Name-based vs. IP-based Virtual Hosts to decide which type they
    want to use, then read more about name-based
    or IP-based virtualhosts, and then see
    some examples.
    

    
    If you want to understand all the details, then you can
    come back to this page.
    


    


    top
    

    

    Configuration File
    

    
    There is a main server which consists of all the
    definitions appearing outside of
    <VirtualHost> sections.
    

    
    There are virtual
    servers, called vhosts, which are defined by
    <VirtualHost>
    sections.
    

    
    Each VirtualHost directive includes one
    or more addresses and optional ports.
    

    
    Hostnames can be used in place of IP addresses in a virtual
    host definition, but they are resolved at startup and if any name
    resolutions fail, those virtual host definitions are ignored.
    This is, therefore, not recommended.
    

    
    The address can be specified as
    *, which will match a request if no
    other vhost has the explicit address on which the request was
    received. 
    

    
    The address appearing in the VirtualHost
    directive can have an optional port. If the port is unspecified,
    it is treated as a wildcard port, which can also be indicated
    explicitly using *.
    The wildcard port matches any port.
    

    
    (Port numbers specified in the VirtualHost directive do
    not influence what port numbers Apache will listen on, they only control
    which VirtualHost will be selected to handle a request.
    Use the Listen directive to
    control the addresses and ports on which the server listens.)
    
    

    
    Collectively the
    entire set of addresses (including multiple
    results from DNS lookups) are called the vhost's
    address set.
    

    
    Apache automatically discriminates on the
    basis of the HTTP Host header supplied by the client
    whenever the most specific match for an IP address and port combination
    is listed in multiple virtual hosts.
    

    
    The
    ServerName directive
    may appear anywhere within the definition of a server. However,
    each appearance overrides the previous appearance (within that
    server).  If no ServerName is specified, the server
    attempts to deduce it from the server's IP address.
    

    
    The first name-based vhost in the configuration file for a
    given IP:port pair is significant because it is used for all
    requests received on that address and port for which no other
    vhost for that IP:port pair has a matching ServerName or
    ServerAlias.  It is also used for all SSL connections if the
    server does not support Server Name Indication.
    

    
    The complete list of names in the VirtualHost
    directive are treated just like a (non wildcard) ServerAlias
    (but are not overridden by any ServerAlias statement).
    

    
    For every vhost various default values are set. In
    particular:
    

    
      
      
    1. If a vhost has no ServerAdmin,
      Timeout,
      KeepAliveTimeout,
      KeepAlive,
      MaxKeepAliveRequests,
      ReceiveBufferSize,
      or SendBufferSize
      directive then the respective value is inherited from the
      main server. (That is, inherited from whatever the final
      setting of that value is in the main server.)
      2. 

      
    2. The "lookup defaults" that define the default directory
      permissions for a vhost are merged with those of the
      main server. This includes any per-directory configuration
      information for any module.
      3. 

      
    3. The per-server configs for each module from the
      main server are merged into the vhost server.
      4. 
    
    

    
    Essentially, the main server is treated as "defaults" or a
    "base" on which to build each vhost. But the positioning of
    these main server definitions in the config file is largely
    irrelevant -- the entire config of the main server has been
    parsed when this final merging occurs. So even if a main server
    definition appears after a vhost definition it might affect the
    vhost definition.
    

    
    If the main server has no ServerName at this
    point, then the hostname of the machine that httpd
    is running on is used instead. We will call the main server address
    set those IP addresses returned by a DNS lookup on the
    ServerName of the main server.
    

    
    For any undefined ServerName fields, a
    name-based vhost defaults to the address given first in the
    VirtualHost statement defining the vhost.
    

    
    Any vhost that includes the magic _default_
    wildcard is given the same ServerName as the
    main server.
    


    top
    

    

    Virtual Host Matching
    

    
    The server determines which vhost to use for a request as
    follows:
    

    
    IP address lookup
    

    
    When the connection is first received on some address and port,
    the server looks for all the VirtualHost definitions
    that have the same IP address and port.
    

    
    If there are no exact matches for the address and port, then
    wildcard (*) matches are considered.
    

    
    If no matches are found, the request is served by the
    main server.
    

    
    If there are VirtualHost definitions for
    the IP address, the next step is to decide if we have to
    deal with an IP-based or a name-based vhost.
    

    

    
    IP-based vhost
    

    
    If there is exactly one VirtualHost directive
    listing the IP address and port combination that was determined
    to be the best match, no further actions are performed and
    the request is served from the matching vhost.
    

    

    
    Name-based vhost
    

    
    If there are multiple VirtualHost directives listing
    the IP address and port combination that was determined to be the
    best match, the "list" in the remaining steps refers to the list of vhosts
    that matched, in the order they were in the configuration file.
    

    
    If the connection is using SSL, the server supports Server Name Indication, and
    the SSL client handshake includes the TLS extension with the
    requested hostname, then that hostname is used below just like the
    Host: header would be used on a non-SSL connection.
    Otherwise, the first name-based vhost whose address matched is
    used for SSL connections.  This is significant because the
    vhost determines which certificate the server will use for the
    connection.
    

    
    If the request contains a Host: header field, the
    list is searched for the first vhost with a matching
    ServerName or ServerAlias, and the
    request is served from that vhost. A Host: header
    field can contain a port number, but Apache always ignores it and
    matches against the real port to which the client sent the
    request.
    

    
    The first vhost in the config
    file with the specified IP address has the highest priority
    and catches any request to an unknown server name, or a request
    without a Host: header field (such as a HTTP/1.0
    request).
    

    

    
    Persistent connections
    

    
    The IP lookup described above is only done once for a
    particular TCP/IP session while the name lookup is done on
    every request during a KeepAlive/persistent
    connection. In other words, a client may request pages from
    different name-based vhosts during a single persistent
    connection.
    

    

    
    Absolute URI
    

    
    If the URI from the request is an absolute URI, and its
    hostname and port match the main server or one of the
    configured virtual hosts and match the address and
    port to which the client sent the request, then the
    scheme/hostname/port prefix is stripped off and the remaining
    relative URI is served by the corresponding main server or
    virtual host. If it does not match, then the URI remains
    untouched and the request is taken to be a proxy request.
    



    Observations
    

    
      
      
    • Name-based virtual hosting is a process applied after
      the server has selected the best matching IP-based virtual
      host.
      • 

      
    • If you don't care what IP address the client has connected to, use a
      "*" as the address of every virtual host, and name-based virtual hosting
      is applied across all configured virtual hosts.
      • 

      
    • ServerName and ServerAlias
      checks are never performed for an IP-based vhost.
      • 

      
    • Only the ordering of
      name-based vhosts for a specific address set is significant.
      The one name-based vhosts that comes first in the
      configuration file has the highest priority for its
      corresponding address set.
      • 

      
    • Any port in the Host: header field is never used during the
      matching process. Apache always uses the real port to which
      the client sent the request.
      • 

      
    • If two vhosts have an address in common, those common addresses
      act as name-based virtual hosts implicitly.  This is new behavior as of
      2.3.11.
      • 

      
    • The main server is only used to serve a request if the IP
      address and port number to which the client connected
      does not match any vhost (including a
      * vhost). In other words, the main server
      only catches a request for an unspecified address/port
      combination (unless there is a _default_ vhost
      which matches that port).
      • 

      
    • You should never specify DNS names in
      VirtualHost directives because it will force
      your server to rely on DNS to boot. Furthermore it poses a
      security threat if you do not control the DNS for all the
      domains listed. There's more
      information available on this and the next two
      topics.
      • 

      
    • ServerName should always be set for each
      vhost. Otherwise a DNS lookup is required for each
      vhost.
      •

    Tips
    

    
    In addition to the tips on the DNS Issues page, here are
    some further tips:
    

    
      
      
    • Place all main server definitions before any
      VirtualHost definitions. (This is to aid the
      readability of the configuration -- the post-config merging
      process makes it non-obvious that definitions mixed in around
      virtual hosts might affect all virtual hosts.)

    verwenden sind.
    

    


    top
    

    

    Namensbasierte gegenüber IP-basierten
    virtuellen Hosts
    

  
    IP-basierte virtuelle Hosts verwenden die IP-Adresse der Verbindung, um den
    korrekten virtuellen Host zur Bedienung einer Anfrage zu ermitteln. Folglich 
    benötigen Sie eine IP-Adresse für jeden virtuellen Host. Bei der 
    Verwendung von namensbasierten virtuellen Hosts verläßt sich der 
    Server darauf, dass der Client den Hostnamen als Bestandteil der HTTP-Header 
    angibt. Durch Anwendung dieser Technik können sich mehrere verschiedene 
    Hosts die gleiche IP-Adresse teilen.
    

  
    Die Verwendung von namensbasierten virtuellen Hosts ist gewöhnlich 
    einfacher. Sie müssen lediglich Ihren DNS-Server darauf einstellen, 
    jeden Hostnamen auf die richtige IP-Adresse abzubilden, und dann den Apache 
    HTTP Server so konfigurieren, dass er die verschiedenen Hostnamen erkennt.
    Namensbasierte virtuelle Hosts entschärfen auch den Bedarf an 
    knappen IP-Adressen. Daher sollten Sie namensbasierte virtuelle Hosts 
    verwenden, sofern kein besonderer Grund dafür existiert, IP-basierte 
    virtuelle Hosts zu wählen. Mögliche Gründe für die 
    Verwendung IP-basierter virtueller Hosts sind:
    

  
      
    
    • Einige antike Clients sind nicht kompatibel zu namensbasierten
      virtuellen Hosts. Damit namensbasierte virtuelle Hosts funktionieren,
      muss der Client den HTTP-Host-Header senden. Dies ist bei HTTP/1.1
      vorgeschrieben und in allen modernen HTTP/1.0-Browsern als Erweiterung
      implementiert. Wenn Sie Unterstützung für veraltete Clients
      benötigen und dennoch namensbasierte virtuelle Hosts verwenden,
      dann finden Sie eine mögliche Lösung dafür am Ende des
      Dokuments.
      • 

    
    • Namensbasierte virtuelle Hosts können aufgrund der Natur des
      SSL-Protokolls nicht mit SSL-gesicherten Servern verwendet werden.
      • 

    
    • Einige Betriebssysteme und Netzwerkanlagen setzen Techniken zum 
      Bandbreiten-Management ein, die nicht zwischen Hosts unterscheiden
      können, wenn diese nicht auf verschiedenen IP-Adressen liegen.
      •

    Die Verwendung von namensbasierten virtuellen Hosts
    

  
    Referenzierte ModuleReferenzierte Direktiven
    

  
    Um namensbasierte virtuelle Hosts zu verwenden, müssen Sie die
    IP-Adresse (und möglicherweise den Port) des Servers benennen, an
    der Anfragen für die Hosts entgegengenommen werden. Dies wird mit
    der Direktive NameVirtualHost
    eingestellt. Im Normalfall, wenn alle IP-Adressen des Server verwendet
    werden sollen, können Sie * als Argument für
    NameVirtualHost verwenden. Wenn Sie
    vorhaben, mehrere Ports zu nutzen (etwa wenn SSL läuft), sollten
    Sie dem Argument einen Port hinzufügen, wie zum Beispiel
    *:80. Beachten Sie,
    dass die Angabe einer IP-Adresse in einer NameVirtualHost-Anweisung den Server nicht
    automatisch an dieser Adresse lauschen läßt. Lesen Sie bitte "Bestimmen der vom Apache verwendeten Adressen und
    Ports" für weitere Details. Zusätzlich muss jede hier
    angegebene IP-Adresse einer Netzwerkkarte des Servers zugeordnet sein.
    
 
  
    Der nächste Schritt ist die Erstellung eines <VirtualHost>-Blocks für jeden einzelnen
    Host, den Sie bedienen wollen. Das Argument der Direktive <VirtualHost> sollte das gleiche
    sein wie das Argument der NameVirtualHost-Anweisung (d.h. eine IP-Adresse
    oder * für alle Adressen). Innerhalb jedes <VirtualHost>-Blocks benötigen
    Sie zumindestens eine ServerName-Anweisung, um zu bestimmen, welcher
    Host bedient wird, und eine DocumentRoot-Anweisung, um anzugeben, wo im
    Dateisystem der Inhalt des Hosts abgelegt ist.
    

  
    Der Hauptserver verschwindet
    
    Wenn Sie virtuelle Hosts zu einem bestehenden Webserver hinzufügen,
    müssen Sie auch einen <VirtualHost>-Block für den bestehenden Host
    (Anm.d.Ü.: und bisherigen Hauptserver) erstellen. 
    Die ServerName- und
    DocumentRoot-Anweisungen zu diesem
    virtuellen Host sollten die gleichen sein wie die globalen ServerName- und DocumentRoot-Anweisungen. Führen Sie diesen
    virtuellen Host als erstes in der Konfigurationsdatei auf, so dass er als
    Standard-Host fungiert.
  
    

  
    Vorausgesetzt, Sie bedienen z.B. die Domain
    www.domain.tld und möchten den virtuellen Host
    www.otherdomain.tld hinzufügen, welcher auf
    die gleiche IP-Adresse zeigt. Dann fügen Sie einfach Folgendes der
    httpd.conf hinzu:
    

    
    
    NameVirtualHost *:80
    
    
    
    <VirtualHost *:80>
    
    
    ServerName www.domain.tld
    
    ServerAlias domain.tld *.domain.tld
    
    DocumentRoot /www/domain
    
        
    </VirtualHost>
    
    
    
    <VirtualHost *:80>
    
    ServerName www.otherdomain.tld
    
    DocumentRoot /www/otherdomain
    
        
    </VirtualHost>
    
    
    

  
    Sie können anstelle des * bei den beiden Anweisungen 
    NameVirtualHost und <VirtualHost> alternativ eine 
    eindeutige IP-Adresse angeben. Das kann man beispielsweise machen, um 
    einige namensbasierte virtuelle Hosts auf einer IP-Adresse zu betreiben und 
    entweder IP-basierte oder ein anderes Set von namensbasierten virtuellen 
    Hosts auf einer anderen Adresse.
    
  
  
    Viele Server wollen unter mehr als einem Namen erreichbar sein. Die 
    Direktive ServerAlias, die innerhalb 
    des <VirtualHost>-Abschnittes angegeben wird,
    ermöglicht dies. Zum Beispiel zeigt die ServerAlias-Anweisung in dem ersten <VirtualHost>-Block oben an, dass die
    aufgeführten Namen alternative Namen sind, die man verwenden kann, um
    das gleiche Webangebot zu erreichen:
    

    
    
    ServerAlias domain.tld *.domain.tld
    
    

  
    Anfragen für alle Hosts der Domain domain.tld werden
    von dem virtuellen Host www.domain.tld bedient. Die
    Platzhalter * und ? können anstelle
    entsprechender Namen verwendet werden. Natürlich können Sie nicht
    einfach Namen erfinden und diese bei ServerName oder ServerAlias
    angeben, Sie müssen zunächst Ihren DNS Server entsprechend
    konfigurieren, dass er diese Namen auf die mit Ihrem Server verknüpfte
    IP-Adresse abbildet.
    

  
    Und schlußendlich können Sie die Konfiguration der virtuellen
    Hosts mittels Angabe weiterer Direktiven innherhalb der <VirtualHost>-Container
    feineinstellen. Die meisten Direktiven können in diesen Containern
    angegeben werden und verändern dann ausschließlich die
    Konfiguration des entsprechenden virtuellen Hosts. Prüfen Sie den Kontext einer Direktive, um
    herauszufinden, ob eine bestimmte Direktive zulässig ist.
    Im Hauptserver-Kontext (außerhalb der <VirtualHost>-Container) definierte
    Konfigurationsanweisungen werden nur dann angewendet, wenn sie nicht durch
    Einstellungen des virtuellen Hosts außer Kraft gesetzt wurden.
    

  
    Wenn nun eine Anfrage eintrifft, prüft der Server zuerst, ob sie eine
    IP-Adresse verwendet, die der NameVirtualHost-Anweisung entspricht. Ist dies der
    Fall, dann sieht er sich jeden <VirtualHost>-Abschnitt mit einer passenden
    IP-Adresse an und versucht den einen zu finden, dessen ServerName- oder ServerAlias-Anweisung mit dem gewünschten
    Hostnamen übereinstimmt. Findet er einen, dann verwendet er die
    Konfiguration dieses Servers. Wird kein passender virtueller Host gefunden,
    dann wird der erste angegeben virtuelle Host verwendet,
    dessen IP-Adresse paßt.
    

  
    Die Folge davon ist, dass der erste aufgeführte virtuelle Host der
    Standard-Virtual-Host ist. Die DocumentRoot-Anweisung des Hauptservers
    wird niemals verwendet, wenn eine IP-Adresse mit einer 
    NameVirtualHost-Anweisung
    übereinstimmt. Wenn Sie eine spezielle Konfiguration für Anfragen
    angeben möchten, die keinem bestimmten virtuellen Host entsprechen,
    packen Sie diese Konfiguration einfach in einen <VirtualHost>-Container und führen diesen als
    erstes in der Konfigurationsdatei auf.

    Kompatibilität mit älteren Browsern
    
  
  
    Wie zuvor erwähnt gibt es einige Clients, die nicht die notwendigen
    Daten senden, mit denen namensbasierte virtuelle Hosts korrekt
    funktionieren. Diesen Clients werden stets die Seiten des ersten, für
    diese IP-Adresse aufgeführten virtuellen Hosts gesendet werden (des
    primären namensbasierten virtuellen Hosts).
    

  
    Was bedeutet älter?
    
    
    Beachten Sie bitte, wenn wir von älter sprechen, meinen wir auch
    älter. Es ist sehr unwahrscheinlich, dass sie einen dieser Browser
    heutzutage in Verwendung finden werden. Alle aktuellen Browser-Versionen
    senden den Host-Header, so wie er für namensbasierte
    virtuelle Hosts benäötigt wird.
    
  
    

  
    Mit der Direktive ServerPath existiert  
    eine mögliche Behelfskonstruktion, obgleich sie etwas schwerfällig
    ist:
    

  
    Beispielkonfiguration:
    

  
    
    NameVirtualHost 111.22.33.44
    
    
    
    <VirtualHost 111.22.33.44>
    
    
    ServerName www.domain.tld
    
    ServerPath /domain
    
    DocumentRoot /web/domain
    
        
    </VirtualHost>
    
  
    

  
    Was bedeutet das? Es bedeutet, dass eine Anfrage für eine mit
    "/domain" beginnende URI von dem virtuellen Host
    www.domain.tld bedient wird. Dies heißt, dass die Seiten
    für alle Clients unter http://www.domain.tld/domain/
    abrufbar sind, wenngleich Clients, die den Header Host:
    senden, auch über http://www.domain.tld/ auf sie zugreifen
    können.
    

  
    Legen Sie einen Link auf der Seite Ihres primären virtuellen Hosts zu 
    http://www.domain.tld/domain/, um die Behelfslösung
    verfügbar zu machen. Bei den Seiten der virtuellen Hosts müssen
    Sie dann sicherstellen, entweder außschließlich relative Links
    (z.B. "file.html" oder
    "../icons/image.gif") zu verwenden oder Links, die das
    einleitende /domain/ enthalten (z.B.,
    "http://www.domain.tld/domain/misc/file.html" oder
    "/domain/misc/file.html").
    

  
    Dies erfordert etwas Disziplin, die Befolgung dieser Richtlinien stellt
    jedoch größtenteils sicher, dass Ihre Seiten mit allen Browsern
    funktionieren, alten wie neuen.

    この文書は、バーチャルホストの設定の際に
    よくある質問に答えるものです。想定している対象は 名前ベース や IP ベース のバーチャルホストを使って
    一つのサーバで複数のウェブサイトを運用している状況です。
    
    


    


    top
    

    

    一つの IP アドレスでいくつかの名前ベースの
    ウェブサイトを実行する
    

    
    サーバは IP アドレスを一つ割り当てられていて、DNS でマシンに
    複数の名前 (CNAME) が指定されています。このマシンで
    www.example.com と www.example.org
    のためのウェブサーバを実行させたいとします。
    

    
    注
    
          Apache サーバの設定でバーチャルホストの設定をしただけで、
          知らない間にそのホスト名に対応する DNS のエントリが
          作成されたりはしません。そのサーバの IP アドレスに解決される
          ように DNS に名前を登録しなければなりません。
          そうでないと誰もあなたのウェブサイトを見ることはできません。
          ローカルでのテストのために hosts ファイルに
          エントリを追加することもできますが、この場合はその
          hosts エントリのあるマシンからしか動作しません。
    
    
    

    
    サーバ設定
    
    

    # Ensure that Apache listens on port 80
    
    Listen 80
    
    
    
    # Listen for virtual host requests on all IP addresses
    
    NameVirtualHost *:80
    
    
    
    <VirtualHost *:80>
    
    
      DocumentRoot /www/example1
    
      ServerName www.example.com
    
      
    
      # Other directives here
    
      
    
        
    </VirtualHost>
    
    
    
    <VirtualHost *:80>
    
    
      DocumentRoot /www/example2
    
      ServerName www.example.org
    
      
    
      # Other directives here
    
      
    
        
    </VirtualHost>
    
    

    
    アスタリスクはすべてのアドレスにマッチしますので、主サーバは
    リクエストを扱いません。www.example.com は
    最初にあるため、優先順位は一番高くなり、default もしくは
    primary  のサーバと考えることができます。つまり、リクエストが
    どの ServerName ディレクティブにもマッチしない場合、
    一番最初の VirtualHost により扱われます。
    

    
    注
    

          
    * をシステムの実際の IP アドレスに置き換える
          こともできます。その場合は VirtualHost の引数は
          NameVirtualHost の引数と同じにしなければなりません
          :
    

            
    
            NameVirtualHost 172.20.30.40
    
            
    
            <VirtualHost 172.20.30.40>
    
             # etc ...
            
    

          
    しかし、IP アドレスが予測不可能なシステム
          ――例えばプロバイダから動的に IP アドレスを取得して何らかの
          ダイナミック DNS を使っている場合など――においては、* 
          指定はさらに便利です。* はすべての IP アドレスに
          マッチしますので、この設定にしておけば IP アドレスが変更されても
          設定変更せずに動作します。
    
    
    

    
    名前ベースのバーチャルホスティングではほぼすべての状況で、
    上記の設定で希望の設定になっていることでしょう。
    実際この設定が動作しないのは、IP アドレスやポートの違いによって
    違うコンテンツを送るときだけです。
    

    
    top
    

    

    複数の IP アドレスのあるホストで名前ベースの
    ホスティングを行なう
    
 
    
    
    
    注
    ここで説明されている方法は IP アドレスが
    何個あっても同様にできます。
    
    
    

    
    サーバには二つ IP アドレスがついています。一つ目
    (172.20.30.40) では主サーバ 
    server.domain.com を扱い、もう一方
    (172.20.30.50) では二つかそれ以上の数の
    バーチャルホストを扱います。
    

    
    サーバの設定
    
    

    Listen 80
    
    
    
    # This is the "main" server running on 172.20.30.40
    
    ServerName server.domain.com
    
    DocumentRoot /www/mainserver
    
    
    
    # This is the other address
    
    NameVirtualHost 172.20.30.50
    
    
    
    <VirtualHost 172.20.30.50>
    
    
        DocumentRoot /www/example1
    
        ServerName www.example.com
    
        
    
        # Other directives here ...
    
        
    
        
    </VirtualHost>
    
    
    
    <VirtualHost 172.20.30.50>
    
    
        DocumentRoot /www/example2
    
        ServerName www.example.org
    
        
    
        # Other directives here ...
    
        
    
        
    </VirtualHost>
    
    

    
    172.20.30.50 以外のアドレスへのリクエストは主サーバ
    が扱います。172.20.30.50 への、未知のホスト名または
    Host: ヘッダなしのリクエストは www.example.com
    が扱います。
    

    
    top
    

    

    違う IP アドレス (例えば、内部と外部アドレス)
    で同じコンテンツを送る
    

    
    サーバマシンは IP アドレスを二つ (192.168.1.1
    と 172.20.30.40) 持っています。このマシンは内部
    (イントラネット) と 外部 (インターネット) のネットワークの間に
    あります。server.example.com はネットワークの外からは
    外部アドレス (172.20.30.40) として解決されますが、
    ネットワークの中からは内部アドレス (192.168.1.1) 
    として解決されます。
    

    
    VirtualHost 一つだけでサーバが内部のリクエストと
    外部のリクエストの両方に同じコンテンツで応答するようにできます。
    

    
    サーバの設定
    
    

    NameVirtualHost 192.168.1.1
    
    NameVirtualHost 172.20.30.40
    
    
    
    <VirtualHost 192.168.1.1 172.20.30.40>
    
    
        DocumentRoot /www/server1
    
        ServerName server.example.com
    
        ServerAlias server
    
        
    </VirtualHost>
    
    

    
    これでどちらのネットワークからのリクエストも同じ VirtualHost
    で扱われるようになります。
    

    
    注:
    内部ネットワークでは完全なホスト名の
          server.example.com の代わりに、単に server
          を使うことができます。
    

          
    上の例では、IP アドレスのリストを、すべてのアドレスに
           同じコンテンツで応答する * に置き換えられます。
    
    
    

    
    top
    

    

    違うポートで違うサイトを運営する
    

    
    同じ IP に複数のドメインがあり、さらに複数のポートを使って
    リクエストを扱いたいときがあります。"NameVirtualHost" タグの中で
    ポートを定義することで、これを動作させられます。
    NameVirtualHost name:port 無しや Listen ディレクティブで
    <VirtualHost name:port> を使おうとしても、その設定は動作しません。
    

    
    サーバの設定

    Virtual_host と
    mod_proxy を併用する
    

    
    次の例は、フロント側のバーチャルホストで他のマシンへプロクシします。
    例では 192.168.111.2 のマシンではバーチャルホスト名は
    同じ名前で設定されています。複数のホスト名を一台のマシンにプロクシする
    場合は、ProxyPreserveHost On
    ディレクティブを使って、希望のホスト名を渡せるようになります。
    
    

    
    
    <VirtualHost *:*>
    
        ProxyPreserveHost On
    
        ProxyPass / http://192.168.111.2/
    
        ProxyPassReverse / http://192.168.111.2/

    _default_ のバーチャルホストを
    使う
     

    
    すべてのポートに対する
    _default_ バーチャルホスト
    

    
    未指定の IP アドレスとポート、つまり他のバーチャルホストに
    使われていないアドレスとポートの組み合わせ、へのすべてのリクエストを
    受け取ります。
    

    
    サーバの設定
    
    

    <VirtualHost _default_:*>
    
    
        DocumentRoot /www/default
    
        
    </VirtualHost>
    
    

    
    このようにワイルドカードのポートでデフォルトのバーチャルホストを
    指定すると、主サーバにリクエストが行くのを防げます。
    

    
    デフォルトのバーチャルホストは名前ベースのバーチャルホストに
    使われているアドレスとポートの組に送られたリクエストを扱うことは
    ありません。リクエストが不明な Host: ヘッダやその
    ヘッダがなかったりする場合は基本名前ベースバーチャルホスト (その
    アドレスとポートで設定ファイル中で最初のバーチャルホスト) により
    扱われます。
    

    
    どんなリクエストでも AliasMatch
    や RewriteRule を使って
    単一の情報ページ (やスクリプト) に書き換えることができます。
    
    

    
    違うポートのための
    _default_ バーチャルホスト
    

    
    一つめの設定とほぼ同じですが、サーバは複数のポートを listen しており、
    80 番ポートに対して二つめの _default_ バーチャルホストを
    設定したい場合です。
    

    
    サーバの設定
    
    

    <VirtualHost _default_:80>
    
    
        DocumentRoot /www/default80
    
        # ...
    
        
    </VirtualHost>
    
    
    
    <VirtualHost _default_:*>
    
    
        DocumentRoot /www/default
    
        # ...
    
        
    </VirtualHost>
    
    

    
    80 番ポートのデフォルトバーチャルホスト (ワイルドカードポートの

    名前ベースのバーチャルホストから IP ベースの

    ホスト名が名前 www.example.org のバーチャルホスト
    (名前ベースの例の 2 番目の設定) が専用の IP アドレスを
    得たとします。名前ベースのバーチャルホストの古い IP アドレスを
    キャッシュしているネームサーバやプロキシのために移行期間中は両方の
    バーチャルホストを提供したいとします。
    

    
    答は簡単です。単に新しい IP アドレス (172.20.30.50)
    を VirtualHost ディレクティブに追加することで
    できます。

    名前ベースのバーチャルホストが二つあるサーバがあるとします。
    正しいバーチャルホストを得るためにはクライアントは正しい
    Host: ヘッダを送らなければなりません。
    古い HTTP/1.0 はそのようなヘッダを送らないので、Apache はクライアントが
    どのバーチャルホストを意図したのかさっぱりわかりません
    (なので、主バーチャルホストでリクエストを扱います)。
    可能な限りの下位互換性を得るため、名前ベースのバーチャルホストの
    URL 接頭辞へのリンクの書かれたページを返す、
    主バーチャルホストが作成されます。

    http://www.sub2.domain.tld/sub1/ へのリクエストも
    Host: ヘッダがなければ sub1-vhost により扱われます。

    Ce document vise à expliquer dans le détail comment le serveur
    HTTP Apache procède lors du choix de l'utilisation
    d'un serveur virtuel en fonction d'une requête reçue.
    

    
    Il est recommandé de lire la documentation
    Serveurs virtuels à base de nom et serveurs virtuels à base
    d'adresse IP pour déterminer quel type de serveur virtuel nous
    convient le mieux, puis de lire les documentations serveurs virtuels à base de nom ou serveurs virtuels à base d'adresse IP, et enfin
    d'étudier quelques exemples.
    

    
    Si vous voulez entrer dans les détails, vous pouvez revenir vers
    cette page.

    Fichier de configuration
    

    
    Un serveur  principal (main_server) contient toutes
    les définitions qui apparaissent en dehors des sections
    <VirtualHost>.
    

    
    Les serveurs virtuels, aussi
    appelés vhosts (pour virtual hosts), sont définis par les
    sections <VirtualHost>.
    

    
    Chaque directive VirtualHost comporte une ou
    plusieurs adresses et des ports optionnels.
    

    
    Il est possible d'utiliser des noms d'hôtes dans la définition
    d'un serveur virtuel, mais ils seront résolus en adresses IP au
    démarrage du serveur, et si une résolution de nom échoue, cette
    définition de serveur virtuel sera ignorée. Cette méthode est par
    conséquent déconseillée.
    

    
    L'adresse peut
    être spécifiée sous la forme *, ce qui conviendra à la
    requête si aucun autre serveur virtuel ne possède l'adresse IP
    explicite correspondant à celle de la requête.
    

    
    L'adresse qui apparaît dans la directive VirtualHost
    peut être associée à un port optionnel. Si aucun port n'est
    spécifié, il s'agit d'un port générique qui peut aussi être spécifié
    comme *. Le port générique correspond à toutes les
    valeurs de port.
    

    
    (Il ne faut pas confondre les numéros de port sur lesquels Apache
    est en écoute avec les numéros de port spécifiés dans la directive
    VirtualHost ; ces derniers ne servent qu'à définir le
    serveur virtuel qui sera sélectionné pour traiter la
    requête. Pour définir les ports sur lesquels Apache est en écoute,
    utilisez la directive Listen).
    
    

    
    L'ensemble des adresses (y compris les résultats multiples
    A issus des requêtes DNS) est appelé jeu
    d'adresses du serveur virtuel.
    

    
    Apache fait automatiquement sa sélection à partir de l'en-tête
    HTTP Host fourni par le client, lorsque la
    correspondance la plus exacte du point de vue adresse IP/port a lieu
    pour plusieurs serveurs virtuels.
    

    
    La directive ServerName peut
    apparaître en quelque endroit de la définition d'un serveur.
    Cependant, chaque occurrence écrase la précédente (pour ce serveur).
    Si aucune directive ServerName n'est spécifiée, le
    serveur tente de déterminer le nom du serveur à partir de l'adresse
    IP.
    

    
    Le premier serveur virtuel à base de nom apparaissant dans le
    fichier de configuration pour une paire IP:port donnée est
    significatif car c'est lui qui sera utilisé pour toutes les requêtes
    reçues sur cette adresse IP/port et pour laquelle aucun autre
    serveur virtuel ne possède un ServerName ou un ServerAlias
    correspondant. Il sera aussi utilisé pour toutes les connexions SSL
    si le serveur ne supporte pas l'Indication du nom du serveur.
    

    
    Tous les noms spécifiés au sein d'une section
    VirtualHost sont traités comme un
    ServerAlias (sans caractères génériques), mais ne sont
    écrasés par aucune directive ServerAlias.
    

    
    Pour chaque serveur virtuel, diverses valeurs sont initialisées
    par défaut. En particulier :
    

    
      
      
    1. Dans le cas où un serveur virtuel ne contient pas de directives
      ServerAdmin,
      Timeout,
      KeepAliveTimeout,
      KeepAlive,
      MaxKeepAliveRequests,
      ReceiveBufferSize,
      ou SendBufferSize,
      alors la valeur de chacun de ces paramètres est héritée de celle du
      serveur principal. (C'est à dire, héritée de la valeur finale après
      lecture de la configuration du serveur principal.)
      2. 

      
    2. Les permissions par défaut sur les répertoires de chaque
      serveur virtuel sont assemblées avec celles du serveur principal.
      Elles concernent également toutes les informations de configuration
      par répertoire pour tous les modules.
      3. 

      
    3. Les configurations par serveur pour chaque module sont assemblées
      à partir de celles du serveur principal.
      4. 
    
    

    
    L'essentiel des valeurs de configuration des serveurs virtuels
    provient de valeurs par défaut issues du serveur principal.
    Mais la position dans le fichier de configuration des directives
    du serveur principal n'a pas d'importance -- l'ensemble de la
    configuration du serveur principal est lu avant que ces valeurs par
    défaut soient appliquées aux serveur virtuels. Ainsi, même si la
    définition d'une valeur apparaît après celle d'un serveur virtuel,
    cette valeur peut affecter la definition du serveur virtuel.
    

    
    Dans le cas où le serveur principal n'a pas de ServerName
    à ce stade, le nom de la machine sur laquelle tourne le programme
    httpd est utilisé à sa place. Nous appellerons
    jeu d'adresses du serveur principal les adresses IP
    renvoyées par une résolution DNS sur le ServerName
    du serveur principal.
    

    
    Pour tous les champs ServerName non définis, dans
    le cas d'une configuration en serveur virtuel par nom, la valeur
    adoptée par défaut est la première adresse donnée dans la section
    VirtualHost qui définit le serveur virtuel.
    

    
    Si un serveur virtuel contient la valeur magique
    _default_, il fonctionne sur le même ServerName
    que le serveur principal.
    


    top
    

    

    Choix du serveur virtuel
    

    
    À la réception d'une requête, le serveur procède comme suit pour
    déterminer quel serveur virtuel utiliser :
    

    
    Recherche de l'adresse IP
    

    
    Lors d'une première connexion sur une adresse/port, le serveur
    recherche toutes les directives VirtualHost qui
    possèdent la même adresse IP/port.
    

    
    S'il n'y a aucune correspondance exacte pour cette adresse/port,
    la recherche s'effectue sur la valeur générique (*).
    

    
    Si aucune correspondance n'est enfin trouvée, la requête sera
    servie par le serveur principal.
    

    
    S'il existe des définitions VirtualHost pour
    l'adresse IP, l'étape suivante consiste à déterminer si nous avons à
    faire à un serveur virtuel à base de nom ou d'adresse IP.
    

    

    
    Serveur virtuel par IP
    

    
    Si une seule section VirtualHost présente la
    meilleure correspondance avec la paire adresse IP/port, aucune
    action n'est entreprise et la requête est
    traitée par le serveur virtuel qui correspond.
    

    

    
    Serveur virtuel par nom
    

    
    Si plusieurs sections VirtualHost présentent la
    meilleure correspondance avec la paire adresse IP/port, le terme
    "liste" dans les étapes suivantes fait référence à la liste des
    serveurs virtuels qui correspondent, selon l'ordre dans lequel ils
    apparaissent dans le fichier de configuration.
    

    
    Si la connexion utilise SSL, si le serveur supporte l'Indication de nom de serveur,
    et si la négociation du client SSL inclut l'extension TLS dans le
    nom d'hôte requis, alors ce nom d'hôte sera utilisé par la suite, tout
    comme un en-tête Host: aurait été utilisé dans le cas
    d'une connexion non-SSL. Si ces conditions ne sont pas réunies, le
    premier serveur virtuel à base de nom dont l'adresse correspond sera
    utilisé pour les connexions SSL. Ceci est important car c'est le
    serveur virtuel qui détermine quel certificat le serveur va utiliser
    pour la connexion.
    

    
    Si la requête contient un en-tête Host:, on
    recherche dans la liste le premier serveur virtuel dont le
    ServerName ou le ServerAlias correspond,
    et c'est celui-ci qui va traiter la requête. Un en-tête
    Host: peut comporter un numéro de port mais Apache
    l'ignore systématiquement et utilise toujours le
    port sur lequel il a effectivement reçu la requête.
    

    
    Le premier serveur virtuel du fichier de configuration qui
    possède l'adresse spécifiée est prioritaire et intercepte toutes les
    requêtes à destination d'un nom de serveur inconnu, ou toute requête
    sans en-tête Host: (comme les requêtes HTTP/1.0).
    

    

    
    Connexions persistantes
    

    
    La recherche par adresse IP décrite ci-avant n'est faite
    qu'une fois pour chaque session TCP/IP, alors que la
    recherche par nom est réalisée pour chaque requête au
    cours d'une connexion persistante (KeepAlive). En d'autres termes,
    il est possible pour un client de faire des requêtes sur
    différents serveurs virtuels par nom, au cours d'une unique
    connexion persistante.
    

    

    
    URI absolu
    

    
    Au cas où l'URI de la requête est absolu, et que son nom de
    serveur et son port correspondent au serveur principal (ou l'un
    des serveurs virtuels configurés), et qu'ils correspondent
    à l'adresse et au port de la requête, alors l'URI est amputé
    de son préfixe protocole/nom de serveur/port et traité par le
    serveur correspondant (principal ou virtuel). Si cette correspondance
    n'existe pas, l'URI reste inchangé et la requête est considérée
    comme une requête d'un serveur mandataire (proxy).
    



    Observations
    

    
      
      
    • La sélection d'un serveur virtuel en fonction de son nom est
      un processus qui intervient après la sélection par le serveur du
      serveur virtuel qui correspond le mieux du point de vue adresse
      IP/port.
      • 

      
    • Si vous ne tenez pas compte de l'adresse IP à laquelle le
      client s'est connecté, indiquez un caractère "*" comme adresse
      pour tous les serveurs virtuels, et la sélection du serveur
      virtuel en fonction du nom s'appliquera alors à tous les serveurs
      virtuels définis.
      • 

      
    • Les vérifications sur ServerName et
      ServerAlias ne sont jamais
      réalisées pour les serveurs virtuels par IP.
      • 

      
    • Seul l'ordre des serveurs virtuels par nom
      pour une adresse donnée a une importance. Le serveur virtuel
      par nom qui est présent en premier dans la configuration se
      voit attribué la priorité la plus haute pour les requêtes
      arrivant sur son jeu d'adresses IP.
      • 

      
    • Le numéro de port contenu dans l'en-tête Host: n'est jamais utilisé
      pour les tests de correspondances. Apache ne prend en compte
      que le numéro de port sur lequel le client a envoyé la requête.
      • 

      
    • Si deux serveurs virtuels partagent la même adresse, la
      sélection se fera implicitement sur le nom. Il s'agit d'une
      nouvelle fonctionnalité de la version 2.3.11.
      • 

      
    • Le serveur principal ne sert les requêtes que
      lorsque l'adresse IP et le port demandés par le client ne
      correspondent à aucun serveur virtuel (y compris un serveur
      virtuel *). En d'autres termes, le serveur
      principal n'est utile que pour les combinaisons adresse/port
      non spécifiées (sauf quand un serveur virtuel _default_
      correspond au port).
      • 

      
    • Il ne faut jamais employer de noms DNS dans des directives
      VirtualHost, car cela oblige le serveur a s'appuyer
      sur le DNS au moment du démarrage. De plus, vous vous exposez
      à des problèmes de sécurité si vous n'avez pas la maîtrise du
      DNS pour la totalité de vos domaines. Voir la documentation
      disponible ici, ainsi que
      les deux points précisés ci-après.
      • 

      
    • Un nom de serveur ServerName devrait toujours
      être indiqué pour chaque serveur virtuel. Sans cela, une
      résolution DNS est nécessaire pour chaque serveur virtuel.

    Trucs et astuces
    

    
    En plus des points évoqués sur la page des
    problèmes liés au DNS,
    voici quelques points intéressants :
    

    
      
      
    • Toujours positionner les définitions relatives au serveur
      principal avant toute définition VirtualHost.
      (Ceci améliore grandement la lisibilité de la configuration
      -- la manière dont la configuration est interprétée après la
      lecture des fichiers ne met pas en évidence le fait que les
      définitions positionnées avant et surtout après les serveurs
      virtuels peuvent impacter le fonctionnement de tous les
      serveurs virtuels.)

    Bu belgede sanal konaklarla ile ilgili olarak
      karşılaşılması olası tüm  senaryolara yer verilmeye çalışılmıştır.
      Buradaki senaryolar, tek bir  sunucu üzerinde  isme dayalı veya IP’ye dayalı
      sanal konaklar aracılığıyla çok sayıda sitenin sunumu ile ilgilidir.

    Tek bir IP ile çok sayıda isme dayalı site
    
    

    
    Bu örnekte, makinenizin tek bir IP adresine çözümlenen çok sayıda konak 
      adına sahip olduğunu, example.com ve 
      example.org gibi farklı isimlere farklı yanıtlar vermek 
      istediğinizi varsayalım.
    
    
    
    Bilginize
    Apache sunucusu üzerinde sanal konakları
      yapılandırmakla bu konak isimleri için sihirli bir şekilde DNS
      kayıtlarının da oluşturulmasını sağlamış olmazsınız. Bu isimler için
      ilgili DNS kayıtlarında sizin IP adresinize çözümlenen A kayıtlarının
      olması gerekir, yoksa sitenize kimse erişemez. Sitelere erişimi yerel
      olarak denemek isterseniz, bu girdileri hosts dosyanıza
      yazabilirsiniz. Fakat bu sadece sizin makinenizde çalışır. Yerel
      ağınızdaki her makinenin hosts dosyasına bu girdileri
      yazarak yerel ağdan erişimi bu yolla sağlayabilirsiniz ama dış ağdan
      gelecek ziyaretçileriniz için DNS kayıtlarınızın olması şarttır.
    
    
    

    
    # Apache’nin 80. portu dinlediğinden emin olalım
Listen 80
<VirtualHost *:80>
  DocumentRoot "/siteler/ecom"
  ServerName example.com

  # Diğer yönergeler, burada ...
</VirtualHost>

<VirtualHost *:80>
  DocumentRoot "/siteler/eorg"
  ServerName example.org

  # Diğer yönergeler, burada ...
</VirtualHost>
    


    
    Yıldız imleri tüm adreslerle eşleşmeyi sağladığından ana sunucu
      (yapılandırma dosyası genelindeki yapılandırma - sunucu geneli)
      erişilebilir olmayacaktır. Yapılandırma
      dosyasındaki ServerName example.com yönergeli konak, ilk
      sanal konak olduğundan en yüksek önceliğe sahiptir ve
      öntanımlı veya baskın site olarak davranır.
      Yani, hiçbir ServerName yönergesi 
      ile eşleşmeyen bir istek alındığında bu istek ilk <VirtualHost> yapılandırması ile
      karşılanır.
    
    
    
    Yukarıdaki yapılandırmayı hemen hemen tüm isme dayalı sanal konaklar
      için kullanabilirsiniz. Bu yapılandırmanın çalışmayacağı tek durum,
      farklı içerikleri farklı IP adres veya portlardan sunma gereğiyle
      karşılaşmaktır.
    

    
    Bilginize
    
      
    * yerine sisteminizdeki belli bir IP adresini 
        yazabilirsiniz. Böyle sanal konaklar sadece, HTTP isteklerinin sadece 
        belirtilen IP adreslerinden alınması için kullanilabilir.
    

      
    NameVirtualHost 192.168.1.22

<VirtualHost 192.168.1.22>
  # vs. ...
</VirtualHost>
    


      
    Bununla birlikte, IP adresinin önceden kestirilebilir olmadığı
        sistemlerde, örneğin, hizmet sağlayıcınıza çevirmeli ağ ile bağlanıyor
        ve onun rasgele atadığı bir IP adresi için bir devingen DNS çözümü
        kullanıyorsanız, IP adresi değil de * kullanmak daha çok
        işinize yarayacaktır. Yıldız imi her IP adresi ile eşleşeceğinden IP
        adresiniz değişse bile bu yapılandırmayı değiştirmeden
        kullanabilirsiniz.

    IP adresleri farklı çok sayıda isme dayalı site
    
    

    
    Bilginize
    
      
    Burada açıklanan teknikler istendiği kadar çok IP adresine
        genişletilebilir.
    
    
    

    
    Sunucunun iki IP adresi olsun. Birinden "ana sunucu"
      (192.168.1.2) diğerinden example.com
      192.168.2.2 hizmet versin. Bu arada başka sanal konakları
      da sunabilelim istiyoruz.
    

    
    Listen 80

# Bu, 192.168.1.2 adresindeki "ana sunucu" olsun
ServerName sunucu.example.com
DocumentRoot "/siteler/anasunucu"

<VirtualHost 192.168.1.20>
    DocumentRoot "/siteler/ecom"
    ServerName example.com

    # Diğer yönergeler, burada ...
</VirtualHost>

<VirtualHost 192.168.1.20>
    DocumentRoot "/siteler/eorg"
    ServerName example.org

    # Diğer yönergeler, burada ...
</VirtualHost>
    


    
    192.168.1.20 adresinden gelmeyen tüm isteklere ana sunucu
      (sunucu.example.com), 192.168.1.20 adresinden
      gelen sunucu ismi belirtmeyenler ile Host: başlığı
      belirtmeyenlere ise  example.com hizmet verecektir.
    

  
    top
    

    

    Aynı içeriği farklı IP adresleriyle sunmak
    (örn., dahili ve harici ağlara)
    

    
    Sunucu makine iki IP adresine sahip olsun. Biri iç ağa
      (192.168.1.1) diğeri dış ağa (172.20.30.40)
      bakıyor olsun. sunucu.example.com ismi dış ağda dış ağa
      bakan IP’ye, iç ağda ise iç ağa bakan IP’ye çözümleniyor olsun.
    

    
    Bu durumda, sunucu hem iç hem de dış ağdan gelen isteklere aynı içerik,
      dolayısıyla aynı <VirtualHost> bölümü ile hizmet verebilir.
    

    
    <VirtualHost 192.168.1.1 172.20.30.40>
    DocumentRoot "/siteler/sunucu"
    ServerName sunucu.example.com
    ServerAlias sunucu
</VirtualHost>
    


    
    Artık, hem iç hem de dış ağdan gelen isteklere aynı
      <VirtualHost> 
      bölümünden hizmet sunulacaktır.
    

    
    Bilginize:
    
      
    İç ağdan istek yapan biri, tam nitelenmiş konak ismi
        sunucu.example.com yerine makine ismini
        (sunucu) kullanabilir (ServerAlias sunucu
        satırına dikkat).
    

      
    Ayrıca, yukarıdaki gibi iki ayrı IP adresi belirtmek yerine sadece
        * belirtmekle sunucunun tüm IP adreslerine yine aynı
        içerikle yanıt vereceğine dikkat ediniz.

    Aynı IP adresine sahip çok sayıda konak ismine sahip olduğunuzu ve
      bunların bazılarının farklı portları kullanmasını istediğinizi
      varsayalım. Aşağıdaki örnekte, isim eşleşmesinin, en iyi eşleşen IP
      adresi ve port çifti saptandıktan sonra yer alması gösterilmiştir.

    Virtualhost ve
    mod_proxy’nin birlikte kullanımı
    

    
    Bu örnekte bir arabirimi dışarıya bakan bir makinede, başka bir
      makinede çalışan bir sunucuya sanal konak olarak, bir vekil sunucu
      çalıştırmak istediğimizi varsayıyoruz. 192.168.111.2 IP
      adresli bir makinede aynı isimde bir sanal konak yapılandırılmış olsun.
      Çok sayıda konak ismi için vekil olarak tek bir makine kullandığımızdan
      ve konak isminin de aktarılmasını arzuladığımızdan ProxyPreserveHost
      On yönergesini kullandık.
    

    
    <VirtualHost *:*>
    ProxyPreserveHost On
    ProxyPass        "/" "http://192.168.111.2/"
    ProxyPassReverse "/" "http://192.168.111.2/"
    ServerName konak.example.com

    _default_ sanal konakları
    

    
    Tüm portlar için _default_
    
      

    
    Bir IP adresi ve port belirtilmeyen veya hiçbir sanal konağın hiçbir
      adresi/portu ile eşleşmeyen istekleri yakalamak istersek...
    

    
    <VirtualHost _default_:*>
    DocumentRoot "/siteler/default"
</VirtualHost>
    


    
    Bütün portlarla eşleşen böyle bir öntanımlı sanal konağın kullanımı
      hiçbir isteğin ana sunucuya gitmemesi sonucunu doğurur.
    

    
    Bir öntanımlı sanal konak, asla, isme dayalı sanal konaklar için
      kullanılmış bir adrese/porta gönderilmiş bir isteğe hizmet sunmaz. Eğer
      istek bilinmeyen bir Host: başlığına sahipse veya hiç
      Host: başlığı içermiyorsa isteğe daima ilk (yapılandırma
      dosyasındaki ilk) isme dayalı sanal konak hizmet sunar.
    

    
    Her isteği tek bir bilgilendirme sayfasına (veya betiğe) yönlendirmek
      isterseniz AliasMatch veya
      RewriteRule yönergesini
      kullanabilirsiniz.
    
    

    
    Farklı portlardan _default_
    
      

    
    Önceki yapılandırmaya ek olarak 80. portta ayrı bir
      _default_ sanal konağı kullanmak istersek...
    

    
    <VirtualHost _default_:80>
    DocumentRoot "/siteler/default80"
    # ...
</VirtualHost>

<VirtualHost _default_:*>
    DocumentRoot "/siteler/default"
    # ...
</VirtualHost>
    


    
    80. porttan hizmet sunan _default_ sanal konağı IP adresi
      belirtilmeyen tüm istekleri yakalar, bunu yapabilmesi için yapılandırma
      dosyasında tüm portlara hizmet sunan benzerinden önce yer almalıdır. Bu
      durumda ana sunucu hiçbir isteğe yanıt vermeyecektir.
    
    

    
    Tek portluk _default_
    
      

    
    _default_ sanal konağının sadece 80. porttan hizmet
      sunmasını istersek...
    

    
    <VirtualHost _default_:80>
    DocumentRoot "/siteler/default"
    ...
</VirtualHost>
    


    
    80. porttan gelen IP adresi belirtilmemiş isteklere
      _default_ sanal konağı, diğer portlardan gelen adres
      belirtilmemiş isteklere ise ana sunucu hizmet verecektir.
    

    
    Bir sanal konak bildiriminde * kullanımı
      _default_ kullanımından daha yüksek öncelik sağlar.

    Bir isme dayalı sanal konağı bir IP’ye dayalı
    sanal konakla yansılamak
    

    
    İsme dayalı sanal konak örneklerinin 2. sinde adı
      geçen example.org bu örnekte kendi IP adresinden hizmet
      veriyor olsun. İsme dayalı sanal konağı eski IP adresiyle kaydetmiş
      vekiller ve isim sunucularından kaynaklanacak olası sorunlardan kaçınmak
      için yansılama sırasında sanal konağı hem eski hem de yeni IP adresiyle
      sunmamız lazım.
    

    
    Çözüm kolay, çünkü yapacağımız sadece VirtualHost
      yönergesine yeni IP adresini (192.168.1.2) eklemek
      olacak.
    

    
    Listen 80
ServerName example.com
DocumentRoot "/siteler/ecom"

<VirtualHost 192.168.1.20 192.168.1.2>
    DocumentRoot "/siteler/eorg"
    ServerName example.org
    # ...
</VirtualHost>

<VirtualHost 192.168.1.20>
    DocumentRoot "/siteler/enet"
    ServerName example.enet
    ServerAlias *.example.net
    # ...
</VirtualHost>
    


    
    Böylece sanal konağa hem yeni (bir IP’ye dayalı sanal konak olarak)
      hem de eski adresinden (bir isme dayalı sanal konak olarak)
      erişilebilecektir.

    ServerPath yönergesinin kullanımı
    
    

    
    İsme dayalı iki sanal konağı olan bir sunucumuz olsun. Doğru sanal
      konağa erişebilmek için istemcinin doğru Host: başlığı
      göndermesi gerekir. Eski HTTP/1.0 istemcileri böyle bir başlık
      göndermedikleri için Apache istemcinin hangi sanal konağa erişmek
      istediğini bilemez (ve isteğe ilk sanal konaktan hizmet sunar). Daha iyi
      bir geriye uyumluluk sağlamak için isme dayalı sanal konağa bir önek
      bağlantısı içeren bir bilgilendirme sayfası sunmak üzere yeni bir sanal
      konak oluşturabiliriz.
    

    
    <VirtualHost 172.20.30.40>
    # ilk sanal konak
    DocumentRoot "/siteler/baska"
    RewriteEngine On
    RewriteRule "." "/siteler/baska/index.html"
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot /siteler/baska/bir
    ServerName "bir.baska.tld"
    ServerPath "/bir/"
    RewriteEngine On
    RewriteRule "^(/bir/.*) /siteler/baska$1"
    # ...
</VirtualHost>

<VirtualHost 172.20.30.40>
    DocumentRoot "/siteler/baska/iki"
    ServerName iki.baska.tld
    ServerPath "/iki/"
    RewriteEngine On
    RewriteRule "^(/iki/.*)" "/siteler/baska$1"
    # ...
</VirtualHost>
    


    
    ServerPath yönergesinden dolayı
      http://bir.baska.tld/bir/ şeklinde yapılan isteklere
      daima “bir” sanal konağı hizmet sunacaktır.
    

    
    http://bir.baska.tld/ şeklinde yapılan isteklere ise
      istemcinin doğru Host: başlığı göndermesi şartıyla
      “bir” sanal konağı hizmet sunacaktır. İstemci, bir
      Host: başlığı göndermediği takdirde ilk konaktan bir
      bilgilendirme sayfası alacaktır.
    

    
    Yalnız buradaki bir tuhaflığa dikkat edin: Eğer istemci bir
      Host: başlığı göndermeden
      http://iki.baska.tld/bir/ şeklinde bir istek yaparsa bu
      isteğe de “bir” sanal konağı hizmet sunacaktır.
    

    
    RewriteRule yönergesi, bir
      istemcinin, bir URL öneki belirtsin ya da belirtmesin doğru
      Host: başlığı gönderdiğinden emin olmak için
      kullanılmıştır.

    システム要件
    

    
    IP ベース という名前が示すように、サーバには
    IP ベースのバーチャルホストそれぞれにつき、別々の IP アドレスが
    必要です。複数の物理コネクションを持っているマシンを用意するか、
    最近のオペレーティングシステムでサポートされているバーチャル
    インタフェース (詳細はシステムの説明書を読んでください。たいていは
    "ip エイリアス" と呼ばれていて、設定には普通 "ifconfig" コマンドを
    使います) を使うかで実現できます。
    

    top
    

    

    Apache の設定方法
    

    
    複数のホストをサポートするように Apache を設定する方法は
    二通りあります。別の httpd デーモンを各ホスト毎に実行するか、
    すべてのバーチャルホストをサポートするデーモンを一つ実行するかです。
    

    
    以下のときには複数のデーモンを使うと良いでしょう:
    

    
      
      
    • 会社1 はウェブ経由以外では会社2 からはデータを読まれたくない、
      といったセキュリティの分離の問題があるとき。この場合、それぞれ
      User, Group, Listen, ServerRoot の設定が違う二つのデーモンを
      実行する必要があります。
      • 

      
    • マシンのすべての IP エイリアスを listen するだけの
      メモリとファイル記述子の余裕があるとき。Listen は「ワイルドカード」
      アドレスか、特定のアドレスのみを listen することができます。
      ですから、何らかの理由で特定のアドレスを listen しなけばならない
      ときは、その特定のアドレスをすべて listen する必要があります。
      (ただし、一つの httpd が N-1 個のアドレスを listen し、
      別の httpd が残りのアドレスを listen するといったことは可能です。)
      • 
    
    

    
    以下のときには単独のデーモンを使うと良いでしょう:
    

    
      
      
    • バーチャルホスト間での httpd の設定を共有してもよいとき。
      • 

      
    • マシンが多くのリクエストを扱うため、別デーモンを実行することによる
      性能の低下の影響が著しいとき。
      • 
    
    


    top
    

    

    複数デーモンの設定
    

    
    各バーチャルホストに対して別の httpd のインストールを行ないます。
    設定ファイル中の Listen 
    ディレクティブを使って、
    各インストールでデーモンが扱う IP アドレス (バーチャルホスト) 
    を選択します。例えば
    

    
    
    Listen www.smallco.com:80
    
    

    
    ここで、ホスト名の代わりに IP アドレスを使う方が推奨されていることに
    注意しておいてください
    (DNS の注意事項 参照)。
    


    top
    

    

    複数のバーチャルホストの設定をした
デーモンを一つ設定する
    

    
    この場合は、一つの httpd が主サーバとすべてのバーチャルホストのリクエストを
    処理します。設定ファイルの VirtualHost ディレクティブを使って、
    ServerAdmin, ServerName, DocumentRoot, ErrorLog, TransferLog
    や CustomLog
    設定ディレクティブの値が各ホスト毎に異なる値に設定されるようにします。
    例えば
    

    
    
    <VirtualHost www.smallco.com>
    
    ServerAdmin webmaster@mail.smallco.com
    
    DocumentRoot /groups/smallco/www
    
    ServerName www.smallco.com
    
    ErrorLog /groups/smallco/logs/error_log
    
    TransferLog /groups/smallco/logs/access_log
    
    </VirtualHost>
    
    
    
    <VirtualHost www.baygroup.org>
    
    ServerAdmin webmaster@mail.baygroup.org
    
    DocumentRoot /groups/baygroup/www
    
    ServerName www.baygroup.org
    
    ErrorLog /groups/baygroup/logs/error_log
    
    TransferLog /groups/baygroup/logs/access_log
    
    </VirtualHost>
    
    

    
    ここで、ホスト名の代わりに IP アドレスを使う方が推奨されていることに
    注意しておいてください
    (DNS の注意事項 参照)。
    

    
    プロセス生成を制御するディレクティブやその他のいくつかのディレクティブを
    除いて、ほぼすべての設定ディレクティブを VirtualHost
    ディレクティブの中に書くことができます。ディレクティブが VirtualHost
    ディレクティブで使用できるかどうかは ディレクティブ索引を使ってコンテキストの
    欄を調べてください。
    

    
    suEXECラッパーを使っている場合は、
    SuexecUserGroup
    ディレクティブを VirtualHost
    ディレクティブの中で使用することができます。
    

    
    セキュリティ: ログファイルを書く場所を指定するときは、
    Apache を起動したユーザ以外がそのディレクトリに書き込み権限を
    持っている場合にセキュリティ上の危険があることに注意してください。
    詳細はセキュリティのこつドキュメントを
    参照してください。

    Le principe des Serveurs Virtuels consiste à 
    faire fonctionner un ou plusieurs serveurs Web (comme 
    www.company1.example.com et www.company2.example.com) 
    sur une même machine. Les serveurs virtuels peuvent être soit 
    "par-IP" où une adresse IP est 
    attribuée pour chaque serveur Web, soit "par-nom" où plusieurs noms de domaine se côtoient sur 
    des mêmes adresses IP. L'utilisateur final ne perçoit pas 
    qu'en fait il s'agit d'un même serveur physique.
    

    
    Apache a été le précurseur des serveurs proposant cette 
    méthode de serveurs virtuels basés sur les adresses IP. Ses 
    versions 1.1 et suivantes proposent les deux 
    méthodes de serveurs virtuels : par-IP et par-nom. Cette 
    deuxième méthode est parfois également appelée host-based 
    ou serveur virtuel non-IP.
    

    
    Vous trouverez ci-dessous une liste documentaire qui vous 
    expliquera en détails le fonctionnement du support des serveurs
    virtuels par le serveur HTTP Apache.

    Directives de configuration
    

    

    
    Pour vérifier et analyser la configuration de vos serveurs 
    virtuels, vous pouvez utiliser l'argument -S sur 
    la ligne de commande.
    

    
    Exemple Unix
    
    
    apachectl -S
    
    

    
    Exemple Windows
    
    
    httpd.exe -S
    
    

    
    Cette commande affichera dans le détail comment Apache a 
    traité son fichier de configuration. Les erreurs de configuration 
    peuvent être corrigées par l'examen attentif des adresses IP et 
    des noms de serveurs. (Consultez la documentation du programme 
    httpd pour les autres arguments de la ligne de 
    commande)

    説明:ホストファイルシステム上のいろいろな違う場所を
    ドキュメントツリーにマップする機能と、
    URL のリダイレクトを行なう機能を提供する
    

    ステータス:Base
    

    モジュール識別子:alias_module
    

    ソースファイル:mod_alias.c
    

    概要
    

    
    このモジュールのディレクティブはサーバにリクエストが到着したときに
    URL の操作や制御をすることを可能にします。Alias
    ディレクティブと ScriptAlias
    ディレクティブは
    URL とファイルシステムのパスをマップするために使用されます。これは
    DocumentRoot
    の下にないドキュメントをウェブのドキュメントツリーの一部として
    送られるようにします。ScriptAlias
    ディレクティブにはマップ先のディレクトリが CGI
    スクリプトのみであることを示すという追加の効果があります。
    
    

    
    Redirect ディレクティブは
    クライアントに違った
    URL に新しいリクエストを送るように指示します。これは、
    リソースが新しい場所に移動したときによく使用されます。
    

    
    mod_alias は簡単な URL 操作向けに設計されています。
    より複雑な操作、クエリーストリングの操作には、mod_rewrite
    で提供されるツールを使用してください。
    


    


    top
    

    

    処理の順番
    


    様々なコンテキスト中での Alias や Redirect は他のディレクティブと
同じように標準の マージ規則 に
従って処理されます。ただし、(例えば <VirtualHost> セクションの中のように) 複数の Alias や Redirect が
同じコンテキスト中に現れた場合は決まった順番で処理されます。
    


    まず、Alias の前にすべての Redirect が処理されます。ですから、Redirect か RedirectMatch にマッチするリクエストには
Alias は決して適用されません。次に、Alias と Redirect が設定ファイル中の
順番に適用され、最初にマッチしたものが優先されます。
    


    ですから、二つ以上のディレクティブが同じパスに適用されるときは、
すべてのディレクティブの効果を得るためにはより詳しいパスを先に書く
必要があります。例えば、次の設定は期待通りの動作をします:
    


    
Alias /foo/bar /baz
    
Alias /foo /gaq

    


    しかし、上記の二つのディレクティブの順番が逆になると、
/foo Alias が
常に /foo/bar Alias より先にマッチしますので、後者は
決して適用されることはありません。
    


    

    top
    

    Alias ディレクティブ
    

    

    説明:URL をファイルシステムの位置にマップする
    

    構文:Alias URL-path
file-path|directory-path
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    Alias ディレクティブはドキュメントを
    ローカルファイルシステムの
    DocumentRoot
    以外の場所に保管することを可能にします。
    URL の (% が復号された) パスが url-path で始まるものは
    directory-filename
    で始まるローカルファイルにマップされます。
    

    
    例
    
      Alias /image /ftp/pub/image
    
    

    
    http://myserver/image/foo.gif へのリクエストに対して、サーバは
    ファイル /ftp/pub/image/foo.gif を返します。
    

    
    もし url-path の最後に /
    を書いたなら、サーバがエイリアスを展開するためには、最後の /
    が必要になることに注意してください。すなわち、Alias /icons/
     /usr/local/apache/icons/ というものを使用している場合は、
    /icons という url はエイリアスされません。
    

    
    エイリアスの行き先を含んでいる <Directory>
    セクションを追加する必要があるかもしれないことに注意してください。
    エイリアスの展開は <Directory>
    セクションを調べる前に行なわれますので、
    エイリアスの行き先の <Directory> セクションのみ
    効果があります。
    (しかし、<Location>
    セクションはエイリアスが処理される前に実行されますので、
    こちらは適用されます。)
    

    
    特に、Alias を
    DocumentRoot
    ディレクトリの外側に配置した場合は、行き先のディレクトリに対する
    アクセス権限を明示的に制限しなければならないでしょう。
    

    
    例
    
        Alias /image /ftp/pub/image
    
        <Directory /ftp/pub/image>
    
        
            Order allow,deny
    
            Allow from all
    
            
        </Directory>
    
    



    

    top
    

    AliasMatch ディレクティブ
    

    

    説明:正規表現を使って URL をファイルシステムの位置にマップする
    

    構文:AliasMatch regex
file-path|directory-path
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    このディレクティブは Alias
    とほとんど同じですが、簡単な先頭からのマッチを行なうのではなく、
    標準正規表現を利用します。ここで指定された正規表現と URL のパス
    が合うかどうかを調べ、合う場合は括弧で括られたマッチを
    与えられた文字列で置き換え、それをファイル名として使用します。たとえば、
    /icons ディレクトリを使う
    ためには以下のようなものが使用できます:
    

    
    
      AliasMatch ^/icons(.*) /usr/local/apache/icons$1
    
    


    

    top
    

    Redirect ディレクティブ
    

    

    説明:クライアントが違う URL を取得するように外部へのリダイレクトを
送る
    

    構文:Redirect [status] URL-path
URL
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    Redirect ディレクティブは古い URL を新しいものへマップします。
    新しい URL がクライアントに返されます。そして、
    クライアントは新しいアドレスをもう一回取得しようとします。
    URL-path (% が復号された) パスで始まるドキュメントへの
    すべてのリクエストは URL で始まる新しい
    (% が符号化された) URL へのリダイレクトエラーが返されます。
    

    
    例
    
      Redirect /service http://foo2.bar.com/service
    
    

    
    クライアントは http://myserver/service/foo.txt
    へのリクエストを行なうと、代わりに http://foo2.bar.com/service/foo.txt
    をアクセスするように告げられます。
    


    注意
    設定ファイル中の順番に関わらず、
Redirect 系のディレクティブは Alias
ディレクティブと ScriptAlias ディレクティブよりも優先されます。
また、.htaccess ファイルや <Directory>
セクションの中で使われていたとしても、URL-path
は相対パスではなく、完全な URL でなければなりません。
    

    
    もし status 引数が与えられていなければ、リダイレクトは
    "temporary" (HTTP ステータス 302) になります。これはクライアントに
    リソースが一時的に移動したということを示します。Status
    引数は 他の HTTP のステータスコードを返すために使用することができます:
    

    
    
      
    permanent
    

      
    永久にリダイレクトをするステータス (301) を返します。
      これはリソースが永久に移動したということを意味します。
    

      
    temp
    

      
    一時的なリダイレクトステータス (302)
      を返します。これがデフォルトです。
    

      
    seeother
    

      
    "See Other" ステータス (303) を返します。
      これはリソースが他のもので置き換えられたことを意味します。
    

    
    gone
    

      
    "Gone" ステータス (410) を返します。これはリソースが永久に
      削除されたことを意味します。このステータスが使用された場合、
      url 引数は省略されなければなりません。
    
    
    

    
    Status の値にステータスコードを数値で与えることで
    他のステータスコードも返すことができます。ステータスが 300 と 399
    の間にある場合、url 引数は存在していなければいけません。
    その他の場合は省略されていなければなりません。ただし、
    ステータスは Apache のコードが知っているものである必要があります
    (http_protocol.c の関数 send_error_response
    を見てください)。
    
    
    例:
    

    
    例
    
      Redirect permanent /one http://example.com/two
    
      Redirect 303 /three http://example.com/other
    
    



    

    top
    

    RedirectMatch ディレクティブ
    

    

    説明:現在の URL への正規表現のマッチにより
外部へのリダイレクトを送る
    

    構文:RedirectMatch [status] regex
URL
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    このディレクティブは Redirect
    とほとんど同じですが、簡単な先頭からのマッチを行なうのではなく、
    標準正規表現を利用します。ここで指定された正規表現と URL-path
    が合うかどうかを調べ、合う場合は括弧で括られたマッチを
    与えられた文字列で置き換え、それをファイル名として使用します。
    たとえば、すべての GIF ファイルを別サーバの同様な名前の JPEG
    ファイルにリダイレクトするには、以下のようなものを使います:
    
    

    
    
      RedirectMatch (.*)\.gif$ http://www.anotherserver.com$1.jpg
    
    


    

    top
    

    RedirectPermanent ディレクティブ
    

    

    説明:クライアントが違う URL を取得するように外部への永久的な
リダイレクトを送る
    

    構文:RedirectPermanent URL-path URL
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    このディレクティブはクライアントに Redirect が永久的なもの
    (ステータス 301) であることを知らせます。
    Redirect permanent とまったく同じです。
    


    

    top
    

    RedirectTemp ディレクティブ
    

    

    説明:クライアントが違う URL を取得するように外部への一時的な

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    このディレクティブはクライアントに Redirect
    が一時的なものである (ステータス 302) ことを知らせます。
    Redirect temp とまったく同じです。

    ScriptAlias ディレクティブ
    

    

    説明:URL をファイルシステムの位置へマップし、マップ先を
CGI スクリプトに指定
    

    構文:ScriptAlias URL-path
file-path|directory-path
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_alias
    

    
    
    ScriptAlias ディレクティブは、対象ディレクトリに
    mod_cgi の cgi-script
    ハンドラで処理される CGI
    スクリプトがあることを示す以外は
    Alias
    ディレクティブと同じ振る舞いをします。
    URL の (% が復号された) パスが URL-path で始まるものは
    ローカルのファイルシステムの
    フルパスである二番目の引数にマップされます。
    

    
    例
    
      ScriptAlias /cgi-bin/ /web/cgi-bin/
    
    

    
    http://myserver/cgi-bin/foo
    へのリクエストに対してサーバはスクリプト
    /web/cgi-bin/foo を実行します。

    Sommaire
    

    
    Le module Status permet à un administrateur de déterminer le
    niveau de performances de son serveur. Les statistiques instantanées
    du serveur sont présentées dans une page HTML sous une forme
    aisément lisible. Si nécessaire, cette page peut être configurée
    pour être automatiquement actualisée (sous réserve de
    compatibilité du navigateur). Une autre page fournit l'état
    instantané du serveur sous la forme d'une simple liste lisible par
    une machine.
    

    
    Les détails fournis sont :
    

    
      
      
    • Le nombre de processus servant les requêtes
      • 

      
    • Le nombre de processus inactifs
      • 

      
    • L'état de chaque processus, le nombre de requêtes qu'il a
      traitées et le nombre total d'octets qu'il a servis (*)
      • 

      
    • Le nombre total d'accès effectués et d'octets servis (*)
      • 

      
    • Le moment où le serveur a été démarré/redémarré et le temps
      écoulé depuis
      • 

      
    • Les valeurs moyennes du nombre de requêtes par seconde, du
      nombre d'octets servis par seconde et du nombre d'octets par
      requête (*)
      • 

      
    • Le pourcentage CPU instantané utilisé par chaque processus et
      par l'ensemble des processus (*)
      • 

      
    • Les hôtes et requêtes actuellement en cours de traitement
      (*)
      • 
    
    

    
    Les lignes se terminant par "(*)" ne sont disponibles que si la
    directive ExtendedStatus
    est définie à On. Depuis la version
    2.3.6, le chargement de mod_status définit automatiquement
    ExtendedStatus à On.
    

    


    top
    

    

    Activation du rapport d'état
    
    

    
    Pour n'activer les rapports d'état que pour les navigateurs
    appartenent au domaine example.com, ajoutez ces lignes à votre
    fichier de configuration httpd.conf :
    

    <Location "/etat-serveur">
    SetHandler server-status
    Require host example.com
</Location>
    


    
    Il est alors possible d'obtenir les statistiques du serveur en
    utilisant un navigateur web et en accédant à la page
    http://votre.serveur/etat-serveur.
    

    top
    

    

    Actualisation automatique
    

    
    
    Vous pouvez faire en sorte que cette page d'état s'actualise
    elle-même automatiquement si votre navigateur supporte "refresh".
    Pour ce faire, accédez à la page
    http://votre.serveur/etat-serveur?refresh=N, pour que
    cette dernière soit actualisée toutes les N secondes.
    


    top
    

    

    Fichier d'état lisible par une machine
    

    
    
    La page http://votre.serveur/etat-serveur?auto
    permet d'obtenir une version du fichier d'état lisible par une
    machine. Ceci s'avère intéressant dans le cadre d'une exécution
    automatique : voir le programme en Perl
    log_server_status situé dans le répertoire
    /support de votre distribution du serveur HTTP Apache.
    

    
    
      Veuillez noter que si mod_status a été
      chargé dans le serveur, son gestionnaire sera disponible dans
      tous les fichiers de configuration, y compris les
      fichiers de configuration de niveau répertoire (par
      exemple .htaccess), ce qui peut avoir des
      répercutions quant à la sécurité de votre site.

    Utilisation de server-status pour la recherche de défauts de
    fonctionnement
    
    

    
    La page server-status peut servir de point de départ
    à la recherche de défauts de fonctionnement lorsque votre serveur
    mobilise toutes les ressources disponibles (CPU ou mémoire), pour
    identifier quels clients ou requêtes sont la cause du problème.
    

    
    Tout d'abord, assurez-vous que la directive ExtendedStatus est bien définie à on, de
    façon à ce que vous puissiez avoir accès à toutes les informations à
    propos de la requête et du client pour chaque processus enfant ou
    thread.
    

    
    Consultez ensuite la liste des processus en cours (à l'aide de
    top, ou d'un utilitaire de listage des processus
    similaire), afin d'identifier les processus coupables. Triez
    l'affichage de top par utilisation CPU ou mémoire, en
    fonction du problème rencontré.
    

    
    Rechargez la page server-status et recherchez
    les identifiants des processus trouvés précédemment ; vous pourrez
    alors déterminer quelle requête est traitée par ces processus, pour
    quel client. Les requêtes peuvent apparaître de manière fugitive, et
    il se peut que vous deviez effectuer plusieurs essais avant de
    parvenir à les prendre en flagrant délit, pour ainsi dire.
    

    
    Cette procédure devrait vous permettre de cerner quel
    client, ou type de requête, sont à l'origine de vos problèmes de
    charge. Il est probable que vous identifiiez une application web au
    comportement anormal, ou un client en train d'attaquer votre site.

    Summary
    

        
    
            mod_tls is an alternative to mod_ssl for providing https to a server.
            It's feature set is a subset, described in more detail below. It can
            be used as a companion to mod_ssl, e.g. both modules can be loaded at
            the same time.
        
    
            mod_tls, being written in C, used the Rust implementation of TLS named
            rustls via its C interface
            rustls-ffi. This gives
            memory safe cryptography and protocol handling at comparable
            performance.
        
    
            It can be configured for frontend and backend connections. The configuration
            directive have been kept mostly similar to mod_ssl ones.

            The above is a minimal configuration. Instead of enabling mod_tls
            in every virtual host, the port for incoming TLS connections is
            specified.
        
    
            You cannot mix virtual hosts with mod_ssl and mod_tls on the same
            port. It's either or. SNI and ALPN are supported. You may use several
            virtual hosts on the same port and a mix of protocols like http/1.1
            and h2.

    Feature Comparison with mod_ssl
    
        
    
            The table below gives a comparison of feature between
            mod_ssl and mod_tls. If a feature of mod_ssl is no listed here,
            it is not supported by mod_tls. The one difference, probably most relevant
            is the lack for client certificate support in the current version of
            mod_tls.

    TLS Protocols
    
        
    
            mod_tls supports TLS protocol version 1.2 and 1.3. Should there ever be
            a version 1.4 and rustls supports it, it will be available as well.
        
    
        
    
            In mod_tls, you configure the minimum version to use, never the maximum:
        
    
        
    TLSProtocol TLSv1.3+
    

        
    
            This allows only version 1.3 and whatever may be its successor one day when talking
            to your server or to a particular virtual host.
    	
    
        
    top
    

    

    TLS Ciphers
    
        
    
            The list of TLS ciphers supported in the rustls library,
            can be found here. All TLS v1.3
            ciphers are supported. For TLS v1.2, only ciphers that rustls considers
            secure are available.
        
    
            mod_tls supports the following names for TLS ciphers:
        
    
        
      
            
    1. 
                The IANA assigned name
                which uses `_` to separate parts. Example: TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
            
      2. 
            
    2. 
                The OpenSSL name, using `-` as separator (for 1.2). Example: ECDHE-ECDSA-AES256-SHA384.
                Such names often appear in documentation. `mod_tls` defines them for all TLS v1.2 ciphers.
                For TLS v1.3 ciphers, names starting with TLS13_ are also supported.
            
      3. 
            
    3. 
                The IANA assigned identifier,
                which is a 16-bit numeric value. Example: 0xc024.
                You can use this in configurations as TLS_CIPHER_0xc024.
            
      4. 
        
    
        
    
            You can configure a preference for ciphers, which means they will be used
            for clients that support them. If you do not configure a preference, rustls
            will use the one that it considers best. This is recommended.
        
    
        
    
            Should you nevertheless have the need to prefer one cipher over another, you
            may configure it like this:
        
    
        
    TLSCiphersPrefer ECDHE-ECDSA-AES256-SHA384
# or several
TLSCiphersPrefer ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305
    

        
    
            If you name a cipher that is unknown, the configuration will fail.
            If you name a cipher is not supported by rustls (or no
            longer supported in an updated version of rustls for security
            reasons), mod_tls will log a WARNING, but continue to work.
    	
    
        
    
            A similar mechanism exists, if you want to disable a particular cipher:
        
    
        
    TLSCipherSuppress ECDHE-ECDSA-AES256-SHA384
    

        
    
            A suppressed cipher will not longer be used.
            If you name a cipher that is unknown, the configuration will fail.
            If you name a cipher is not supported by rustls (or no
            longer supported in an updated version of rustls for security
            reasons), mod_tls will log a WARNING, but continue to work.
        
    
        
    top
    

    

    Virtual Hosts
    
        
    
            mod_tls uses the SNI (Server Name Indicator) to select one of the
            configured virtual hosts that match the port being served. Should
            the client not provide an SNI, the first configured
            virtual host will be selected. If the client does provide
            an SNI (as all today's clients do), it must match one
            virtual host (ServerName or ServerAlias)
            or the connection will fail.
        
    
        
    
            As with mod_ssl, you may specify ciphers and protocol
            versions for the base server (global) and/or individual virtual hosts
            that are selected via SNI by the client.

            The example above show different TLS settings for virtual hosts on the
            same port. This is supported. example1 can be contacted via
            all TLS versions and example2 only allows v1.3 or later.

    ACME Certificates
    
        
    
            ACME certificates via mod_md are supported, just as
            for mod_ssl. A minimal configuration:

    OCSP Stapling
    
        
    
            mod_tls has no own implementation to retrieve OCSP information for
            a certificate. However, it will use such for Stapling if it is provided
            by mod_md. See mod_md's documentation
            on how to enable this.

    TLS Variables
    
        
    
            Via the directive TLSOptions, several variables
            are placed into the environment of requests and can be inspected, for
            example in a CGI script.
        
    
        
    
            The variable names are given by mod_ssl. Note that these
            are only a subset of the many variables that mod_ssl exposes.

    Client Certificates
    
        
    
            While rustls supports client certificates in principle, parts
            of the infrastructure to make use of these in a server are not
            offered.
        
    
        
    
            Among these features are: revocation lists, inspection of certificate
            extensions and the matched issuer chain for OCSP validation. Without these,
            revocation of client certificates is not possible. Offering authentication
            without revocation is not considered an option.
        
    
        
    
            Work will continue on this and client certificate support may become
            available in a future release.

                If you do not specify a separate key file, the key is assumed to also be

    TLSCiphersPrefer Directive

                This will not disable any ciphers supported by `rustls`. If you
                specify a cipher that is completely unknown, the configuration will
                fail. If you specify a cipher that is known but not supported by `rustls`,
                a warning will be logged but the server will continue.
            
    
            
    
            
    Example
    TLSCiphersPrefer ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305
    

    
            
    
                The example gives 2 ciphers preference over others, in the
                order they are mentioned.

    Example
    TLSCiphersSuppress ECDHE-ECDSA-CHACHA20-POLY1305

                It will affect all `VirtualHost` that match the specified address/port.
                You can use `TLSEngine` several times to use more than one address/port.
            
    
            
    
            
    Example
    TLSEngine 443
    

    
            
    
                The example tells mod_tls to handle incoming connection on port 443 for

    Context:server config, virtual host, directory, .htaccess
    

    Status:Experimental
    

    Module:mod_tls
    

    
            
    
                TLSOptions is analog to `SSLOptions` in mod_ssl.
                It can be set per directory/location and `option` can be:
            
    
            
      
                
    • `StdEnvVars`: adds more variables to the requests environment,
                    as forwarded for example to CGI processing and other applications.
                
      • 
                
    • `ExportCertData`: adds certificate related variables to the request environment.
                
      • 
                
    • `Defaults`: resets all options to their default values.
      • 
            
    
            
    
                Adding variables to a request environment adds overhead, especially
                when certificates need to be inspected and fields extracted.
                Therefore most variables are not set by default.
            
    
            
    
                You can configure `TLSOptions` per location or generally on a
                server/virtual host. Prefixing an option with `-` disables this
                option while leaving others unchanged.
                A `+` prefix is the same as writing the option without one.
            
    
            
    
                The `Defaults` value can be used to reset any options that are
                inherited from other locations or the virtual host/server.
            
    
            
    Example
    <Location /myplace/app>
  TLSOptions Defaults StdEnvVars
  ...

    Source File:mod_version.c
    

    Summary
    

    
    This module is designed for the use in test suites and large
    networks which have to deal with different httpd versions and
    different configurations. It provides a new container -- <IfVersion>, which
    allows a flexible version checking including numeric comparisons and
    regular expressions.
    

    
    Examples
    <IfVersion 2.4.2>
    # current httpd version is exactly 2.4.2
</IfVersion>

<IfVersion >= 2.5>
    # use really new features :-)
</IfVersion>
    

    

    
    See below for further possibilities.

    <IfVersion> Directive
    

    

    Description:contains version dependent configuration

    Context:server config, virtual host, directory, .htaccess
    

    Override:All
    

    Status:Extension
    

    Module:mod_version
    

    
    
    The <IfVersion> section encloses
    configuration directives which are executed only if the
    httpd version
    matches the desired criteria. For normal (numeric) comparisons the
    version argument has the format
    major[.minor[.patch]], e.g.
    2.1.0 or 2.2. minor and
    patch are optional. If these numbers are omitted, they are
    assumed to be zero. The following numerical operators are
    possible:
    

    
    operatordescription
    

    = or ==
        httpd version is equal
    

    >
        httpd version is greater than
    

    >=
        httpd version is greater or equal
    

    <
        httpd version is less than
    

    <=
        httpd version is less or equal
    

    

    
    Example
    <IfVersion >= 2.3>
    # this happens only in versions greater or
    # equal 2.3.0.
</IfVersion>
    

    

    
    Besides the numerical comparison it is possible to match a
    regular expression
    against the httpd version. There are two ways to write it:
    

    
    operatordescription
    

    = or ==
        version has the form
            /regex/
    

    ~
        version has the form
            regex
    

    

    
    Example
    <IfVersion = /^2.4.[01234]$/>
    # e.g. workaround for buggy versions
</IfVersion>
    

    

    
    In order to reverse the meaning, all operators can be preceded by an
    exclamation mark (!):
    

    
    <IfVersion !~ ^2.4.[01234]$>
    # not for those versions
</IfVersion>
    


    
    If the operator is omitted, it is assumed to be
    =.

de certainescaractéristiques de la requête

    Identificateur de Module:setenvif_module
    

    Fichier Source:mod_setenvif.c
    

    Sommaire
    


    
    Le module mod_setenvif vous permet de définir
    des variables d'environnement internes de manière conditionnelle en fonction
    de critères que vous pouvez spécifier. Ces variables d'environnement
    peuvent être utilisées par d'autres parties du serveur pour prendre
    des décisions quant aux actions à entreprendre, et pour déterminer
    si les scripts CGI et les pages SSI doivent pouvoir y accéder.
    

    
    Les directives sont interprétées selon l'ordre dans lequel elles
    apparaîssent dans les fichiers de configuration. Ainsi, des
    séquences plus complexes peuvent être utilisées, comme dans cet
    exemple qui définit netscape si le navigateur est Mozilla et non
    MSIE.
    


    BrowserMatch ^Mozilla netscape
BrowserMatch MSIE !netscape
    


   
    Lorsque le serveur cherche un chemin via une sous-requête interne (par exemple la
   recherche d'un DirectoryIndex), ou lorsqu'il génère un
   listing du contenu d'un répertoire via le module
   mod_autoindex, la sous-requête n'hérite pas des
   variables d'environnement spécifiques à la requête. En outre, à cause
   des phases de l'API auxquelles mod_setenvif prend
   part, les directives SetEnvIf ne sont pas évaluées
   séparément dans la sous-requête.

  d'environnement en fonction du contenu de l'en-tête de requête HTTP
  User-Agent. Les deux lignes suivantes produisent le même
  effet :

    La directive BrowserMatchNoCase est
    identique sur le plan sémantique à la directive BrowserMatch. Elle permet
    cependant une comparaison insensible à la casse. Par exemple :
    

    BrowserMatchNoCase mac platform=macintosh
BrowserMatchNoCase win platform=windows
    


    
    Les directives BrowserMatch et
    BrowserMatchNoCase sont des cas particuliers
    des directives SetEnvIf
    et SetEnvIfNoCase.
    Ainsi, les deux lignes suivantes produisent le même effet :
    

    BrowserMatchNoCase Robot is_a_robot
SetEnvIfNoCase User-Agent Robot is_a_robot

    Directive SetEnvIf
    

    

    Description:Définit des variables d'environnement en fonction des
attributs de la requête
    

    Syntaxe:SetEnvIf attribut
    regex [!]env-variable[=valeur]
    [[!]env-variable[=valeur]] ...

    Statut:Base
    

    Module:mod_setenvif
    

    
    
    La directive SetEnvIf permet de définir
    des variables d'environnement en fonction des attributs de la
    requête. L'attribut spécifié comme premier argument peut
    se présenter sous l'une des trois formes suivantes :
    


      

    1. Un champ d'en-tête de requête HTTP (voir la RFC2616 pour
    plus d'information à leur propos) ; par exemple : Host,
    User-Agent, Referer, ou
    Accept-Language. Il est possible d'utiliser une
    expression rationnelle pour spécifier un jeu d'en-têtes de
    requête.
      2. 


    2. Une des caractéristiques de la requête suivantes :
    
        
      
      • Remote_Host - le nom d'hôte (s'il est disponible)
      du client qui effectue la requête
        • 

      
      • Remote_Addr - l'adresse IP du client qui effectue
      la requête
        • 

      
      • Server_Addr - l'adresse IP du serveur qui a reçu
      la requête (uniquement à partir des versions supérieures à
      2.0.43)
        • 

      
      • Request_Method - Le nom de la méthode HTTP
      utilisée (GET, POST, et
      cetera...)
        • 

      
      • Request_Protocol - le nom et la version du
      protocole utilisé pour la requête (par exemple "HTTP/0.9",
      "HTTP/1.1", etc...)
        • 

      
      • Request_URI - la ressource demandée dans la ligne
      de requête HTTP -- en général la partie de l'URL suivant le
      protocole et le nom du serveur, sans la chaîne d'arguments. Voir
      la directive RewriteCond du module
      mod_rewrite pour plus d'informations sur la
      manière de mettre en correspondance votre chaîne d'arguments.
        • 
    
      

      3. 


    3. Le nom d'une variable d'environnement parmi la liste de celles qui
sont associées à la requête. Ceci permet à la directive
SetEnvIf d'effectuer des tests en fonction du
résultat de comparaisons précédentes. Seules les variables
d'environnement définies par des directives
SetEnvIf[NoCase] précédentes sont disponibles pour
effectuer des tests de cette manière. 'Précédentes' signifie qu'elles se
trouvent à un niveau plus global de la configuration (par exemple au
niveau du serveur principal), ou plus haut chronologiquement dans le
contexte de la directive. Les variables d'environnement ne seront prises
en compte que si aucune correspondance n'a été trouvée parmi les
caractéristiques de la requête, et si attribut n'a pas été
spécifié sous la forme d'une expression rationnelle.
      4. 


    


    Le second argument (regex) est une expression rationnelle. Si  regex
correspond à l'attribut, les arguments suivants sont évalués.
    


    Le reste des arguments constitue les noms des variables à définir,
ainsi que les valeurs optionnelles qui doivent leur être affectées. Ils
peuvent se présenter sous les formes suivantes :
    

    
      
      
    1. nom-variable, ou
      2. 

      
    2. !nom-variable, ou
      3. 

      
    3. nom-variable=valeur
      4. 
    
    

    
    Dans la première forme, la valeur sera définie à "1". Dans la
    seconde forme, la variable sera supprimée si elle a été définie au
    préalable, et dans la troisième forme, la variable sera définie à la
    valeur littérale spécifiée par valeur. Depuis
    la version 2.0.51, Apache httpd reconnaît les occurrences de variables
    $1..$9 à l'intérieur de
    valeur, et les remplace par les
    sous-expressions entre parenthèses correspondantes de
    regex. $0 permet d'accéder à l'ensemble de la chaîne
    qui correspond à ce modèle.
    


    SetEnvIf Request_URI "\.gif$" object_is_image=gif
SetEnvIf Request_URI "\.jpg$" object_is_image=jpg
SetEnvIf Request_URI "\.xbm$" object_is_image=xbm
    
SetEnvIf Referer www\.mydomain\.example\.com intra_site_referral
    
SetEnvIf object_is_image xbm XBIT_PROCESSING=1

SetEnvIf Request_URI "\.(.*)$" EXTENSION=$1
    
SetEnvIf ^TS  ^[a-z]  HAVE_TS
    


    
    Les trois premières lignes définissent la variable
    d'environnement objet_est_une_image si l'objet de la
    requête est un fichier image, et la quatrième définit la variable
    intra_site_referral si la page référante se trouve
    quelque part dans le site web
    www.mydomain.example.com.
    

    
    La dernière ligne définit la variable d'environnement
    HAVE_TS si la requête contient un en-tête dont le nom
    commence par "TS" et dont la valeur commence par tout caractère du
    jeu [a-z].

    Statut:Base
    

    Module:mod_setenvif
    

    
    
    La directive SetEnvIfExpr permet de
    définir des variables d'environnement en fonction d'une expression
    <If> ap_expr. Cette
    expression est évaluée à l'exécution, et utilise les variables
    d'environnement env-variable de la même manière que la
    directive SetEnvIf.
    


    SetEnvIfExpr "tolower(req('X-Sendfile')) == 'd:\images\very_big.iso')" iso_delivered
    


    
    Dans cet exemple, la variable d'environnement
    iso_delivered est définie chaque fois que notre
    application tente de l'envoyer via X-Sendfile.
    

    
    Il pourrait être plus utile de définir une variable rfc1918 si
    l'adresse IP distante est une adresse privée au sens de la RFC 1918
    :
    


    SetEnvIfExpr "-R '10.0.0.0/8' || -R '172.16.0.0/12' || -R '192.168.0.0/16'" rfc1918

    La directive SetEnvIfNoCase est identique
    d'un point de vue sémantique à la directive SetEnvIf, et ne s'en distingue que
    par le fait que la comparaison des expressions rationnelles est
    effectuée sans tenir compte de la casse. Par exemple :
    

    SetEnvIfNoCase Host Example\.Org site=example
    


    
    Cette ligne va définir la variable d'environnement
    site avec la valeur "example" si le champ
    d'en-tête de requête HTTP Host: est présent et contient
    Example.Org, example.org, ou une autre
    combinaison des mêmes caractères, sans tenir compte de la casse.

    Description:Provides a rule-based rewriting engine to rewrite requested
URLs on the fly
    

    Status:Extension
    

    Module Identifier:rewrite_module
    

    Source File:mod_rewrite.c
    

    Summary
    

	
    The mod_rewrite module uses a rule-based rewriting
      engine, based on a PCRE regular-expression parser, to rewrite requested URLs on
      the fly. By default, mod_rewrite maps a URL to a filesystem
      path. However, it can also be used to redirect one URL to another URL, or
      to invoke an internal proxy fetch.
    
      
    mod_rewrite provides a flexible and powerful way to
      manipulate URLs using an unlimited number of rules. Each rule can have an
      unlimited number of attached rule conditions, to allow you to rewrite URL
      based on server variables, environment variables, HTTP headers, or time
      stamps.
    
      
    mod_rewrite operates on the full URL path, including the
      path-info section. A rewrite rule can be invoked in
      httpd.conf or in .htaccess. The path generated
      by a rewrite rule can include a query string, or can lead to internal
      sub-processing, external request redirection, or internal proxy
      throughput.
    

      
    Further details, discussion, and examples, are provided in the
      detailed mod_rewrite documentation.

    Logging
    

    
    mod_rewrite offers detailed logging of its actions
    at the trace1 to trace8 log levels. The
    log level can be set specifically for mod_rewrite
    using the LogLevel directive: Up to
    level debug, no actions are logged, while trace8
    means that practically all actions are logged.
    

    
    
      Using a high trace log level for mod_rewrite
      will slow down your Apache HTTP Server dramatically! Use a log
      level higher than trace2 only for debugging!
    
    

    
    Example
    LogLevel alert rewrite:trace3
    

    

    
    RewriteLog
    
      
    Those familiar with earlier versions of
      mod_rewrite will no doubt be looking for the
      RewriteLog and RewriteLogLevel
      directives. This functionality has been completely replaced by the
      new per-module logging configuration mentioned above.
      
    

      
    To get just the mod_rewrite-specific log
      messages, pipe the log file through grep:
    
    
    
    tail -f error_log|fgrep '[rewrite:'

    RewriteBase Directive
    

    

    Description:Sets the base URL for per-directory rewrites
    

    Syntax:RewriteBase URL-path
    

    Default:None
    

    Context:directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_rewrite
    

    
      
    The RewriteBase directive specifies the
      URL prefix to be used for per-directory (htaccess)
      RewriteRule directives that
      substitute a relative path.
    
      
     This directive is required when you use a relative path
      in a substitution in per-directory (htaccess) context unless any 
      of the following conditions are true:
    
      
      
          
    •  The original request, and the substitution, are underneath the
               DocumentRoot
               (as opposed to reachable by other means, such as
               Alias).
      • 
          
    •  The filesystem path to the directory containing the
               RewriteRule,
               suffixed by the relative
               substitution is also valid as a URL path on the server
               (this is rare).
      • 
          
    •  In Apache HTTP Server 2.4.16 and later, this directive may be
                omitted when the request is mapped via
                Alias
                or mod_userdir.
      • 
      
    


     In the example below, RewriteBase is necessary
    to avoid rewriting to http://example.com/opt/myapp-1.2.3/welcome.html
    since the resource was not relative to the document root.  This
    misconfiguration would normally cause the server to look for an "opt"
    directory under the document root.
    

    DocumentRoot "/var/www/example.com"
AliasMatch "^/myapp" "/opt/myapp-1.2.3"
<Directory "/opt/myapp-1.2.3">
    RewriteEngine On
    RewriteBase "/myapp/"
    RewriteRule "^index\.html$"  "welcome.html"
</Directory>

    RewriteCond Directive
    

    

    Description:Defines a condition under which rewriting will take place

    

    Syntax: RewriteCond
      TestString CondPattern [flags]
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_rewrite
    

    
      
    The RewriteCond directive defines a
      rule condition. One or more RewriteCond
      can precede a RewriteRule
      directive. The following rule is then only used if both
      the current state of the URI matches its pattern, and if these conditions are met.
    

      
    TestString is a string which can contain the
      following expanded constructs in addition to plain text:
    

      
      
        
    • 
          RewriteRule backreferences: These are
          backreferences of the form $N
          (0 <= N <= 9). $1 to $9 provide access to the grouped
          parts (in parentheses) of the pattern, from the
          RewriteRule which is subject to the current
          set of RewriteCond conditions. $0 provides
          access to the whole string matched by that pattern.
        
      • 
        
    • 
          RewriteCond backreferences: These are
          backreferences of the form %N
          (0 <= N <= 9). %1 to %9 provide access to the grouped
          parts (again, in parentheses) of the pattern, from the last matched
          RewriteCond in the current set
          of conditions. %0 provides access to the whole string matched by
          that pattern.
        
      • 
        
    • 
          RewriteMap expansions: These are
          expansions of the form ${mapname:key|default}.
          See the documentation for
          RewriteMap for more details.
        
      • 
        
    • 
          Server-Variables: These are variables of
          the form
            %{ NAME_OF_VARIABLE
            }
          where NAME_OF_VARIABLE can be a string taken
          from the following list:

                or elsewhere in the Manual or in the CGI specification.
      

                
      SERVER_NAME and SERVER_PORT depend on the values of
                UseCanonicalName and
                UseCanonicalPhysicalPort
                respectively.
      

                
      Those that are special to mod_rewrite include those below.
      
                
      
                  
      API_VERSION
      

                  
      This is the version of the Apache httpd module API
                  (the internal interface between server and
                  module) in the current httpd build, as defined in
                  include/ap_mmn.h. The module API version
                  corresponds to the version of Apache httpd in use (in
                  the release version of Apache httpd 1.3.14, for
                  instance, it is 19990320:10), but is mainly of
                  interest to module authors.
      

                  
      CONN_REMOTE_ADDR
      

                  
      Since 2.4.8: The peer IP address of the connection (see the
                  mod_remoteip module).
      

                  
      HTTPS
      

                  
      Will contain the text "on" if the connection is
                  using SSL/TLS, or "off" otherwise.  (This variable
                  can be safely used regardless of whether or not
                  mod_ssl is loaded).
      

                  
      IS_SUBREQ
      

                  
      Will contain the text "true" if the request
                  currently being processed is a sub-request,
                  "false" otherwise. Sub-requests may be generated
                  by modules that need to resolve additional files
                  or URIs in order to complete their tasks.
      

                  
      REMOTE_ADDR
      

                  
      The IP address of the remote host (see the
                  mod_remoteip module).
      

                  
      REQUEST_FILENAME
      

                  
      The full local filesystem path to the file or
                  script matching the request, if this has already
                  been determined by the server at the time
                  REQUEST_FILENAME is referenced. Otherwise,
                  such as when used in virtual host context, the same
                  value as REQUEST_URI.  Depending on the value of
                  AcceptPathInfo, the
                  server may have only used some leading components of the
                  REQUEST_URI to map the request to a file.
                  
      

                  
      REQUEST_SCHEME
      

                  
      Will contain the scheme of the request (usually
                  "http" or "https"). This value can be influenced with
                  ServerName.
      

                  
      REQUEST_URI
      

                  
      The path component of the requested URI,
                  such as "/index.html".  This notably excludes the
                  query string which is available as its own variable
                  named QUERY_STRING.
      

                  
      THE_REQUEST
      

                  
      The full HTTP request line sent by the
                  browser to the server (e.g., "GET
                  /index.html HTTP/1.1"). This does not
                  include any additional headers sent by the
                  browser.  This value has not been unescaped
                  (decoded), unlike most other variables below.
      

                
      
        
      • 
      
    

      
    If the TestString has the special value expr,
      the CondPattern will be treated as an
      ap_expr. HTTP headers referenced in the
      expression will be added to the Vary header if the novary
      flag is not given.
    

      
    Other things you should be aware of:
    

      
      
        
    1. 
        
      The variables SCRIPT_FILENAME and REQUEST_FILENAME
        contain the same value - the value of the
        filename field of the internal
        request_rec structure of the Apache HTTP Server.
        The first name is the commonly known CGI variable name
        while the second is the appropriate counterpart of
        REQUEST_URI (which contains the value of the
        uri field of request_rec).
      
        
      If a substitution occurred and the rewriting continues,
        the value of both variables will be updated accordingly.
      
        
      If used in per-server context (i.e., before the
        request is mapped to the filesystem) SCRIPT_FILENAME and
        REQUEST_FILENAME cannot contain the full local filesystem
        path since the path is unknown at this stage of processing.
        Both variables will initially contain the value of REQUEST_URI
        in that case. In order to obtain the full local filesystem
        path of the request in per-server context, use an URL-based
        look-ahead %{LA-U:REQUEST_FILENAME} to determine
        the final value of REQUEST_FILENAME.
      2. 

        
    2. 
        %{ENV:variable}, where variable can be
        any environment variable, is also available.
        This is looked-up via internal
        Apache httpd structures and (if not found there) via
        getenv() from the Apache httpd server process.
      3. 

        
    3. 
        %{SSL:variable}, where variable is the
        name of an SSL environment
        variable, can be used whether or not
        mod_ssl is loaded, but will always expand to
        the empty string if it is not.  Example:
        %{SSL:SSL_CIPHER_USEKEYSIZE} may expand to
        128. These variables are available even without
        setting the StdEnvVars option of the
        SSLOptions directive.
      4. 

        
    4. 
        %{HTTP:header}, where header can be
        any HTTP MIME-header name, can always be used to obtain the
        value of a header sent in the HTTP request.
        Example: %{HTTP:Proxy-Connection} is
        the value of the HTTP header
        ``Proxy-Connection:''.
        
      If a HTTP header is used in a condition this header is added to
        the Vary header of the response in case the condition evaluates
        to true for the request. It is not added if the
        condition evaluates to false for the request. Adding the HTTP header
        to the Vary header of the response is needed for proper caching.
      
        
      It has to be kept in mind that conditions follow a short circuit
        logic in the case of the 'ornext|OR' flag
        so that certain conditions might not be evaluated at all.
      5. 

        
    5. 
        %{LA-U:variable}
        can be used for look-aheads which perform
        an internal (URL-based) sub-request to determine the final
        value of variable. This can be used to access
        variable for rewriting which is not available at the current
        stage, but will be set in a later phase.
        
      For instance, to rewrite according to the
        REMOTE_USER variable from within the
        per-server context (httpd.conf file) you must
        use %{LA-U:REMOTE_USER} - this
        variable is set by the authorization phases, which come
        after the URL translation phase (during which
        mod_rewrite operates).
      
        
      On the other hand, because mod_rewrite implements
        its per-directory context (.htaccess file) via
        the Fixup phase of the API and because the authorization
        phases come before this phase, you just can use
        %{REMOTE_USER} in that context.
      6. 

        
    6. 
        %{LA-F:variable} can be used to perform an internal
        (filename-based) sub-request, to determine the final value
        of variable. Most of the time, this is the same as
        LA-U above.
      7. 
      
    

      
    CondPattern is the condition pattern,
       a regular expression which is applied to the
      current instance of the TestString.
      TestString is first evaluated, before being matched against
      CondPattern.
    

      
    CondPattern is usually a
      perl compatible regular expression, but there is
      additional syntax available to perform other useful tests against
      the Teststring:
    

      
      
        
    1. You can prefix the pattern string with a
        '!' character (exclamation mark) to negate the result
        of the condition, no matter what kind of CondPattern is used.
        
      2. 

        
    2. 
          You can perform lexicographical string comparisons:

          
      
            
      <CondPattern
      
            
      Lexicographically precedes
      
            Treats the CondPattern as a plain string and
            compares it lexicographically to TestString. True if
            TestString lexicographically precedes
            CondPattern.
      

            
      >CondPattern
      
            
      Lexicographically follows
      
            Treats the CondPattern as a plain string and
            compares it lexicographically to TestString. True if
            TestString lexicographically follows
            CondPattern.
      

            
      =CondPattern
      
            
      Lexicographically equal
      
            Treats the CondPattern as a plain string and
            compares it lexicographically to TestString. True if
            TestString is lexicographically equal to
            CondPattern (the two strings are exactly
            equal, character for character). If CondPattern
            is "" (two quotation marks) this
            compares TestString to the empty string.
      

            
      <=CondPattern
      
            
      Lexicographically less than or equal to
      
            Treats the CondPattern as a plain string and
            compares it lexicographically to TestString. True
            if TestString lexicographically precedes
            CondPattern, or is equal to CondPattern
            (the two strings are equal, character for character).
      

            
      >=CondPattern
      
            
      Lexicographically greater than or equal to
      
            Treats the CondPattern as a plain string and
            compares it lexicographically to TestString. True
            if TestString lexicographically follows
            CondPattern, or is equal to CondPattern
            (the two strings are equal, character for character).
      
        
      
        
      Note
      
        The string comparison operator is part of the CondPattern
        argument and must be included in the quotes if those are used. Eg.
        
        
      RewriteCond %{HTTP_USER_AGENT} "=This Robot/1.0"
      

        
      
        
        
      3. 

        
    3. 
          You can perform integer comparisons:
          
      

            
      -eq
      
            
      Is numerically equal to
      
            The TestString is treated as an integer, and is
            numerically compared to the CondPattern. True if
            the two are numerically equal.
      

            
      -ge
      
            
      Is numerically greater than or equal to
      
            The TestString is treated as an integer, and is
            numerically compared to the CondPattern. True if
            the TestString is numerically greater than or equal
            to the CondPattern.
      

            
      -gt
      
            
      Is numerically greater than
      
            The TestString is treated as an integer, and is
            numerically compared to the CondPattern. True if
            the TestString is numerically greater than
            the CondPattern.
      

            
      -le
      
            
      Is numerically less than or equal to
      
            The TestString is treated as an integer, and is
            numerically compared to the CondPattern. True if
            the TestString is numerically less than or equal
            to the CondPattern. Avoid confusion with the
            -l by using the -L or
            -h variant.
      

            
      -lt
      
            
      Is numerically less than
      
            The TestString is treated as an integer, and is
            numerically compared to the CondPattern. True if
            the TestString is numerically less than
            the CondPattern. Avoid confusion with the
            -l by using the -L or
            -h variant.
      

            
      -ne
      
            
      Is numerically not equal to
      
            The TestString is treated as an integer, and is
            numerically compared to the CondPattern. True if
            the two are numerically different. This is equivalent to
            !-eq.
      

           
      
        
      4. 

        
    4. You can perform various file attribute tests:


          
      

          
      -d
      

          
      Is directory.
      
             Treats the TestString as a pathname and tests
            whether or not it exists, and is a directory.
          
      

          
      -f
      

          
      Is regular file.
      

             Treats the TestString as a pathname and tests
            whether or not it exists, and is a regular file.
        
      

           
      -F
      

           
      Is existing file, via subrequest.
      
            Checks whether or not TestString is a valid file,
            accessible via all the server's currently-configured
            access controls for that path. This uses an internal
            subrequest to do the check, so use it with care -
            it can impact your server's performance!
           
      

            
      -h
      
            
      Is symbolic link, bash convention.
      
            See -l.
            
      

            
      -l
      

            
      Is symbolic link.
      
            Treats the TestString as a pathname and tests
            whether or not it exists, and is a symbolic link. May also
            use the bash convention of -L or
            -h if there's a possibility of confusion
            such as when using the -lt or
            -le tests.
            
      

            
      -L
      
            
      Is symbolic link, bash convention.
      
            See -l.
      

            
      -s
      
            
      Is regular file, with size.
      
            Treats the TestString as a pathname and tests
            whether or not it exists, and is a regular file with size greater
            than zero.
      

            
      -U
      
            
      Is existing URL, via subrequest.
      
            Checks whether or not TestString is a valid URL,
            accessible via all the server's currently-configured
            access controls for that path. This uses an internal
            subrequest to do the check, so use it with care -
            it can impact your server's performance!
      
            
       This flag only returns information about things
            like access control, authentication, and authorization.  This flag
            does not return information about the status code the
            configured handler (static file, CGI, proxy, etc.) would have
            returned.
       
      

            
      -x
      
            
      Has executable permissions.
      
            Treats the TestString as a pathname and tests
            whether or not it exists, and has executable permissions.
            These permissions are determined according to
            the underlying OS.
      

          
      

          For example:

        
      RewriteCond /var/www/%{REQUEST_URI} !-f
RewriteRule ^(.+) /other/archive/$1 [R]
      


        
      5. 

        
    5. 
           
      If the TestString has the special value expr, the
           CondPattern will be treated as an
           ap_expr.
      

           
      
            In the below example, -strmatch is used to
            compare the REFERER against the site hostname,
            to block unwanted hotlinking.
           
      

           
      RewriteCond expr "! %{HTTP_REFERER} -strmatch '*://%{HTTP_HOST}/*'"
RewriteRule "^/images" "-" [F]
      

        
      6. 
     
    

     
    You can also set special flags for CondPattern by appending
        [flags]
      as the third argument to the RewriteCond
      directive, where flags is a comma-separated list of any of the
      following flags:
    
      
      
      
        
    • 'nocase|NC'
        (no case)
      
        This makes the test case-insensitive - differences
        between 'A-Z' and 'a-z' are ignored, both in the
        expanded TestString and the CondPattern.
        This flag is effective only for comparisons between
        TestString and CondPattern. It has no
        effect on filesystem and subrequest checks.
      • 

        
    • 
          'ornext|OR'
          (or next condition)
      
          Use this to combine rule conditions with a local OR
          instead of the implicit AND. Typical example:


      RewriteCond "%{REMOTE_HOST}"  "^host1"  [OR]
RewriteCond "%{REMOTE_HOST}"  "^host2"  [OR]
RewriteCond "%{REMOTE_HOST}"  "^host3"
RewriteRule ...some special stuff for any of these hosts...
      


          Without this flag you would have to write the condition/rule
          pair three times.
        
      • 

        
    • 'novary|NV'
        (no vary)
      
        If a HTTP header is used in the condition, this flag prevents
        this header from being added to the Vary header of the response. 
      
        Using this flag might break proper caching of the response if
        the representation of this response varies on the value of this header.
        So this flag should be only used if the meaning of the Vary header
        is well understood.

    Example:
    

       
    To rewrite the Homepage of a site according to the
        ``User-Agent:'' header of the request, you can
        use the following: 
    


    RewriteCond  "%{HTTP_USER_AGENT}"  "(iPhone|Blackberry|Android)"
RewriteRule  "^/$"                 "/homepage.mobile.html"  [L]

RewriteRule  "^/$"                 "/homepage.std.html"     [L]
    


        
    Explanation: If you use a browser which identifies itself
        as a mobile browser (note that the example is incomplete, as
        there are many other mobile platforms), the mobile version of
        the homepage is served. Otherwise, the standard page is served.

    RewriteEngine Directive
    

    

    Description:Enables or disables runtime rewriting engine
    

    Syntax:RewriteEngine on|off
    

    Default:RewriteEngine off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_rewrite
    

    

      
    The RewriteEngine directive enables or
      disables the runtime rewriting engine. If it is set to
      off this module does no runtime processing at
      all. It does not even update the SCRIPT_URx
      environment variables.
    

      
    Use this directive to disable rules in a particular context,
      rather than commenting out all the RewriteRule directives.
    

      
    Note that rewrite configurations are not
      inherited by virtual hosts. This means that you need to have a
      RewriteEngine on directive for each virtual host
      in which you wish to use rewrite rules.
    

      
    RewriteMap directives
      of the type prg

    RewriteMap Directive
    

    

    Description:Defines a mapping function for key-lookup
    

    Syntax:RewriteMap MapName MapType:MapSource
    [MapTypeOptions]

    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_rewrite
    

    Compatibility:The 3rd parameter, MapTypeOptions, in only available from Apache
2.4.29 and later
    

    
      
    The RewriteMap directive defines a
      Rewriting Map which can be used inside rule
      substitution strings by the mapping-functions to
      insert/substitute fields through a key lookup. The source of
      this lookup can be of various types.
    

      
    The MapName is
      the name of the map and will be used to specify a
      mapping-function for the substitution strings of a rewriting
      rule via one of the following constructs:
    

      
    
        ${ MapName :
        LookupKey }
    
         ${ MapName :
        LookupKey | DefaultValue
        }    
      
    

      
    When such a construct occurs, the map MapName is
      consulted and the key LookupKey is looked-up. If the
      key is found, the map-function construct is substituted by
      SubstValue. If the key is not found then it is
      substituted by DefaultValue or by the empty string
      if no DefaultValue was specified. Empty values
      behave as if the key was absent, therefore it is not possible
      to distinguish between empty-valued keys and absent keys.
    

      
    For example, you might define a
      RewriteMap as:
    

      
    RewriteMap examplemap "txt:/path/to/file/map.txt"
    


      
    You would then be able to use this map in a
      RewriteRule as follows:
    

      
    RewriteRule "^/ex/(.*)" "${examplemap:$1}"
    


      
    The meaning of the MapTypeOptions argument depends on
      particular MapType. See the
      Using RewriteMap for
      more information.
    

      
    The following combinations for MapType and
      MapSource can be used:
    

    
    

    
    txt
    
        
    A plain text file containing space-separated key-value
        pairs, one per line. (Details ...)
    

    
    rnd
    
        
    Randomly selects an entry from a plain text file (Details ...)
    

    
    dbm
    
        
    Looks up an entry in a dbm file containing name, value
        pairs. Hash is constructed from a plain text file format using
        the httxt2dbm
        utility.  (Details ...)
    

    
    int
    
        
    One of the four available internal functions provided by
        RewriteMap: toupper, tolower, escape or
        unescape. (Details ...)
    

    
    prg
    
        
    Calls an external program or script to process the
        rewriting. (Details ...)
    

    
    dbd or fastdbd
    
        
    A SQL SELECT statement to be performed to look up the
        rewrite target. (Details ...)

    RewriteOptions Directive
    

    

    Description:Sets some special options for the rewrite engine
    

    Syntax:RewriteOptions Options
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_rewrite
    

    

      
    The RewriteOptions directive sets some
      special options for the current per-server or per-directory
      configuration. The Option string can currently
      only be one of the following:
    

      
    
      
    Inherit
    
      
    

      
    This forces the current configuration to inherit the
      configuration of the parent. In per-virtual-server context,
      this means that the maps, conditions and rules of the main
      server are inherited. In per-directory context this means
      that conditions and rules of the parent directory's
      .htaccess configuration or
      <Directory>
      sections are inherited. The inherited rules are virtually copied
      to the section where this directive is being used. If used in
      combination with local rules, the inherited rules are copied behind
      the local rules. The position of this directive - below or above
      of local rules - has no influence on this behavior. If local
      rules forced the rewriting to stop, the inherited rules won't
      be processed.
    

      
    
      Rules inherited from the parent scope are applied
      after rules specified in the child scope.
      
    
      
    

      
    InheritBefore
    
      
    
      
     Like Inherit above, but the rules from the parent scope
      are applied before rules specified in the child scope.
    
      Available in Apache HTTP Server 2.3.10 and later.
    
      
    

      
    InheritDown
    
      
    

      
    If this option is enabled, all child configurations will inherit
      the configuration of the current configuration. It is equivalent to
      specifying RewriteOptions Inherit in all child
      configurations. See the Inherit option for more details
      on how the parent-child relationships are handled.
    
      Available in Apache HTTP Server 2.4.8 and later.
    
      
    

      
    InheritDownBefore
    
      
    

      
    Like InheritDown above, but the rules from the current
      scope are applied before rules specified in any child's
      scope.
    
      Available in Apache HTTP Server 2.4.8 and later.
    
      
    

      
    IgnoreInherit
    
      
    

      
    This option forces the current and child configurations to ignore
      all rules that would be inherited from a parent specifying
      InheritDown or InheritDownBefore.
    
      Available in Apache HTTP Server 2.4.8 and later.
    
      
    

      
    AllowNoSlash
    
      
    
      
    By default, mod_rewrite will ignore URLs that map to a
      directory on disk but lack a trailing slash, in the expectation that
      the mod_dir module will issue the client with a redirect to
      the canonical URL with a trailing slash.
    

      
    When the DirectorySlash directive
      is set to off, the AllowNoSlash option can be enabled to ensure
      that rewrite rules are no longer ignored. This option makes it possible to
      apply rewrite rules within .htaccess files that match the directory without
      a trailing slash, if so desired.
    
      Available in Apache HTTP Server 2.4.0 and later.
    
      
    

      
    AllowAnyURI
    
      
    

      
    When RewriteRule
      is used in VirtualHost or server context with
      version 2.2.22 or later of httpd, mod_rewrite
      will only process the rewrite rules if the request URI is a URL-path.  This avoids
      some security issues where particular rules could allow
      "surprising" pattern expansions (see CVE-2011-3368
      and CVE-2011-4317).
      To lift the restriction on matching a URL-path, the
      AllowAnyURI option can be enabled, and
      mod_rewrite will apply the rule set to any
      request URI string, regardless of whether that string matches
      the URL-path grammar required by the HTTP specification.
    
      Available in Apache HTTP Server 2.4.3 and later.
    

      
    
      
    Security Warning
    

      
    Enabling this option will make the server vulnerable to
      security issues if used with rewrite rules which are not
      carefully authored.  It is strongly recommended
      that this option is not used.  In particular, beware of input
      strings containing the '@' character which could
      change the interpretation of the transformed URI, as per the
      above CVE names.
    
      
    
      
    

      
    MergeBase
    
      
    

      
    With this option, the value of RewriteBase is copied from where it's explicitly defined
      into any sub-directory or sub-location that doesn't define its own
      RewriteBase. This was the
      default behavior in 2.4.0 through 2.4.3, and the flag to restore it is
      available Apache HTTP Server 2.4.4 and later.
    
      
    

      
    IgnoreContextInfo
    
      
    

      
    When a relative substitution is made
         in directory (htaccess) context and RewriteBase has not been set, this module uses some
         extended URL and filesystem context information to change the
         relative substitution back into a URL. Modules such as
         mod_userdir and mod_alias
         supply this extended context info.  Available in 2.4.16 and later.
    
      
    


      
    LegacyPrefixDocRoot
    
      
    

      
    Prior to 2.4.26, if a substitution was an absolute URL that matched
         the current virtual host, the URL might first be reduced to a URL-path
         and then later reduced to a local path. Since the URL can be reduced 
         to a local path, the path should be prefixed with the document root. 
         This prevents a file such as /tmp/myfile from being accessed when a 
         request is made to http://host/file/myfile with the following 
         RewriteRule.
    
      
    RewriteRule /file/(.*) http://localhost/tmp/$1
    

      
    This option allows the old behavior to be used where the document
         root is not prefixed to a local path that was reduced from a 
         URL.  Available in 2.4.26 and later.

    RewriteRule Directive
    

    

    Description:Defines rules for the rewriting engine
    

    Syntax:RewriteRule
      Pattern Substitution [flags]
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_rewrite
    

    
      
    The RewriteRule directive is the real
      rewriting workhorse. The directive can occur more than once,
      with each instance defining a single rewrite rule. The
      order in which these rules are defined is important - this is the order
      in which they will be applied at run-time.
    

      
    Pattern is
      a perl compatible regular
      expression.  What this pattern is compared against varies depending
      on where the RewriteRule directive is defined. 
    


    What is matched?
    


      
      
    • In VirtualHost context,
      The Pattern will initially be matched against the part of the
      URL after the hostname and port, and before the query string (e.g. "/app1/index.html").
      This is the (%-decoded) URL-path.
      • 

      
    • In per-directory context (Directory and .htaccess),
      the Pattern is matched against only a partial path, for example a request
      of "/app1/index.html" may result in comparison against "app1/index.html" 
      or "index.html" depending on where the RewriteRule is 
      defined.
      

      
      The directory path where the rule is defined is stripped from the currently mapped
      filesystem path before comparison (up to and including a trailing slash). 
      The net result of this per-directory prefix stripping is that rules in
      this context only match against the portion of the currently mapped filesystem path 
      "below" where the rule is defined.
      

      
      Directives such as DocumentRoot and Alias, or even the 
      result of previous RewriteRule substitutions, determine
      the currently mapped filesystem path.  
      
      
      
      • 

      
    • If you wish to match against the hostname, port, or query string, use a
      RewriteCond with the
      %{HTTP_HOST}, %{SERVER_PORT}, or
      %{QUERY_STRING} variables respectively.
      • 

    

    


    Per-directory Rewrites
    

      

    • The rewrite engine may be used in .htaccess files and in <Directory> sections, with some additional
complexity.
      • 


    • To enable the rewrite engine in this context, you need to set
"RewriteEngine On" and
"Options FollowSymLinks" must be enabled. If your
administrator has disabled override of FollowSymLinks for
a user's directory, then you cannot use the rewrite engine. This
restriction is required for security reasons.
      • 


    • See the RewriteBase
directive for more information regarding what prefix will be added back to
relative substitutions.
      • 


    •  If you wish to match against the full URL-path in a per-directory
(htaccess) RewriteRule, use the %{REQUEST_URI} variable in
a RewriteCond.
      • 


    • The removed prefix always ends with a slash, meaning the matching occurs against a string which
never has a leading slash.  Therefore, a Pattern with ^/ never
matches in per-directory context.
      • 


    • Although rewrite rules are syntactically permitted in <Location> and <Files> sections
(including their regular expression counterparts), this
should never be necessary and is unsupported. A likely feature
to break in these contexts is relative substitutions.
      • 


    • The If blocks
follow the rules of the directory context.
      • 


    • By default, mod_rewrite overrides rules when 
merging sections belonging to the same context. The RewriteOptions directive can change this behavior,
for example using the Inherit setting.
      • 


    • The RewriteOptions also regulates the
behavior of sections that are stated at the same nesting level of the configuration. In the
following example, by default only the RewriteRules stated in the second 
If block
are considered, since the first ones are overridden. Using RewriteOptions Inherit forces mod_rewrite to merge the two
sections and consider both set of statements, rather than only the last one.
      • 

    

    <If "true">
  # Without RewriteOptions Inherit, this rule is overridden by the next
  # section and no redirect will happen for URIs containing 'foo'
  RewriteRule foo http://example.com/foo [R]
</If>
<If "true">
  RewriteRule bar http://example.com/bar [R]
</If>
    

    

    

      
    For some hints on regular
      expressions, see
      the mod_rewrite
      Introduction.
    

      
    In mod_rewrite, the NOT character
      ('!') is also available as a possible pattern
      prefix. This enables you to negate a pattern; to say, for instance:
      ``if the current URL does NOT match this
      pattern''. This can be used for exceptional cases, where
      it is easier to match the negative pattern, or as a last
      default rule.
    


    Note
    
When using the NOT character to negate a pattern, you cannot include
grouped wildcard parts in that pattern. This is because, when the
pattern does NOT match (ie, the negation matches), there are no
contents for the groups. Thus, if negated patterns are used, you
cannot use $N in the substitution string!

    

      
    The Substitution of a
      rewrite rule is the string that replaces the original URL-path that
      was matched by Pattern.  The Substitution may
      be a:
    

      
    

        
    file-system path
    

        
    Designates the location on the file-system of the resource
        to be delivered to the client.  Substitutions are only
        treated as a file-system path when the rule is configured in
        server (virtualhost) context and the first component of the
        path in the substitution exists in the file-system
    

        
    URL-path
    

        
    A DocumentRoot-relative path to the
        resource to be served. Note that mod_rewrite
        tries to guess whether you have specified a file-system path
        or a URL-path by checking to see if the first segment of the
        path exists at the root of the file-system. For example, if
        you specify a Substitution string of
        /www/file.html, then this will be treated as a
        URL-path unless a directory named www
        exists at the root or your file-system (or, in the case of
        using rewrites in a .htaccess file, relative to
        your document root), in which case it will
        be treated as a file-system path. If you wish other
        URL-mapping directives (such as Alias) to be applied to the
        resulting URL-path, use the [PT] flag as
        described below.
    

        
    Absolute URL
    

        
    If an absolute URL is specified,
        mod_rewrite checks to see whether the
        hostname matches the current host. If it does, the scheme and
        hostname are stripped out and the resulting path is treated as
        a URL-path. Otherwise, an external redirect is performed for
        the given URL. To force an external redirect back to the
        current host, see the [R] flag below.
    

        
    - (dash)
    

        
    A dash indicates that no substitution should be performed
        (the existing path is passed through untouched). This is used
        when a flag (see below) needs to be applied without changing
        the path.
    

      
    

      
    In addition to plain text, the Substitution string can include
    

      
      
        
    1. back-references ($N) to the RewriteRule
        pattern
      2. 

        
    2. back-references (%N) to the last matched
        RewriteCond pattern
      3. 

        
    3. server-variables as in rule condition test-strings
        (%{VARNAME})
      4. 

        
    4. mapping-function calls
        (${mapname:key|default})
      5. 
      
    

      
    Back-references are identifiers of the form
      $N
      (N=0..9), which will be replaced
      by the contents of the Nth group of the
      matched Pattern. The server-variables are the same
      as for the TestString of a
      RewriteCond
      directive. The mapping-functions come from the
      RewriteMap
      directive and are explained there.
      These three types of variables are expanded in the order above.
    

      
    Rewrite rules are applied to the results of previous rewrite
      rules, in the order in which they are defined
      in the config file. The URL-path or file-system path (see "What is matched?", above) is completely
      replaced by the Substitution and the
      rewriting process continues until all rules have been applied,
      or it is explicitly terminated by an
      L flag,
      or other flag which implies immediate termination, such as
      END or
      F.
    

     
    Modifying the Query String
    
      
    By default, the query string is passed through unchanged. You
      can, however, create URLs in the substitution string containing
      a query string part. Simply use a question mark inside the
      substitution string to indicate that the following text should
      be re-injected into the query string. When you want to erase an
      existing query string, end the substitution string with just a
      question mark. To combine new and old query strings, use the
      [QSA] flag.
    
     
    

      
    Additionally you can set special actions to be performed by
      appending [flags]
      as the third argument to the RewriteRule
      directive. Flags is a comma-separated list, surround by square
      brackets, of any of the flags in the following table. More
      details, and examples, for each flag, are available in the Rewrite Flags document.

    Home directory expansion
    

     When the substitution string begins with a string
resembling "/~user" (via explicit text or backreferences), mod_rewrite performs
home directory expansion independent of the presence or configuration
of mod_userdir.
    


     This expansion does not occur when the PT
flag is used on the RewriteRule
directive.
    

    


     
    Here are all possible substitution combinations and their
      meanings:

    Description:Context-sensitive smart filter configuration module
    

    Status:Base
    

    Module Identifier:filter_module
    

    Source File:mod_filter.c
    

    Compatibility:Version 2.1 and later
    

    Summary
    

    
    This module enables smart, context-sensitive configuration of
    output content filters.  For example, apache can be configured to
    process different content-types through different filters, even
    when the content-type is not known in advance (e.g. in a proxy).
    

    
    mod_filter works by introducing indirection into
    the filter chain.  Instead of inserting filters in the chain, we insert
    a filter harness which in turn dispatches conditionally
    to a filter provider.  Any content filter may be used as a provider
    to mod_filter; no change to existing filter modules is
    required (although it may be possible to simplify them).

    Smart Filtering
    
    
    In the traditional filtering model, filters are inserted unconditionally
    using AddOutputFilter and family.
    Each filter then needs to determine whether to run, and there is little
    flexibility available for server admins to allow the chain to be
    configured dynamically.
    

    
    mod_filter by contrast gives server administrators a
    great deal of flexibility in configuring the filter chain.  In fact,
    filters can be inserted based on complex boolean
    expressions This generalises the limited
    flexibility offered by AddOutputFilterByType.

    Filter Declarations, Providers and Chains
    
    
    
    [This image displays the traditional filter model]
    
    Figure 1: The traditional filter model
    

    
    In the traditional model, output filters are a simple chain
    from the content generator (handler) to the client.  This works well
    provided the filter chain can be correctly configured, but presents
    problems when the filters need to be configured dynamically based on
    the outcome of the handler.
    

    
    
    [This image shows the mod_filter model]
    
    Figure 2: The mod_filter model
    

    
    mod_filter works by introducing indirection into
    the filter chain.  Instead of inserting filters in the chain, we insert
    a filter harness which in turn dispatches conditionally
    to a filter provider.  Any content filter may be used as a provider
    to mod_filter; no change to existing filter modules
    is required (although it may be possible to simplify them).  There can be
    multiple providers for one filter, but no more than one provider will
    run for any single request.
    

    
    A filter chain comprises any number of instances of the filter
    harness, each of which may have any number of providers.  A special
    case is that of a single provider with unconditional dispatch: this
    is equivalent to inserting the provider filter directly into the chain.
    

    top
    

    

    Configuring the Chain
    
    
    There are three stages to configuring a filter chain with
    mod_filter. For details of the directives, see below.
    

    
    
    
    Declare Filters
    
    
    The FilterDeclare directive
    declares a filter, assigning it a name and filter type.  Required
    only if the filter is not the default type AP_FTYPE_RESOURCE.
    

    
    Register Providers
    
    
    The FilterProvider
    directive registers a provider with a filter. The filter may have
    been declared with FilterDeclare; if not, FilterProvider will implicitly
    declare it with the default type AP_FTYPE_RESOURCE. The provider
    must have been
    registered with ap_register_output_filter by some module.
    The final argument to FilterProvider is an expression: the provider will be
    selected to run for a request if and only if the expression evaluates
    to true.  The expression may evaluate HTTP request or response
    headers, environment variables, or the Handler used by this request.
    Unlike earlier versions, mod_filter now supports complex expressions
    involving multiple criteria with AND / OR logic (&& / ||)
    and brackets. The details of the expression syntax are described in
    the ap_expr documentation.
    

    
    Configure the Chain
    
    
    The above directives build components of a smart filter chain,
    but do not configure it to run.  The FilterChain directive builds a filter chain from smart
    filters declared, offering the flexibility to insert filters at the
    beginning or end of the chain, remove a filter, or clear the chain.
    

    

    top
    

    

    Filtering and Response Status
    
    
    mod_filter normally only runs filters on responses with
    HTTP status 200 (OK).  If you want to filter documents with
    other response statuses, you can set the filter-errordocs
    environment variable, and it will work on all responses
    regardless of status.  To refine this further, you can use
    expression conditions with FilterProvider.
    

    top
    

    

    Upgrading from Apache HTTP Server 2.2 Configuration
    
    
    The FilterProvider
    directive has changed from httpd 2.2: the match and
    dispatch arguments are replaced with a single but
    more versatile expression.  In general, you can convert
    a match/dispatch pair to the two sides of an expression, using
    something like:
    
    
    "dispatch = 'match'"
    
    
    The Request headers, Response headers and Environment variables
    are now interpreted from syntax %{req:foo},
    %{resp:foo} and %{env:foo} respectively.
    The variables %{HANDLER} and %{CONTENT_TYPE}
    are also supported.
    
    
    Note that the match no longer support substring matches.  They can be
    replaced by regular expression matches.
    

    top
    

    

    Examples
    
    
    
    
    Server side Includes (SSI)
    
    
    A simple case of replacing AddOutputFilterByType
    
    FilterDeclare SSI
FilterProvider SSI INCLUDES "%{CONTENT_TYPE} =~ m|^text/html|"
FilterChain SSI
    

    
    

    
    Server side Includes (SSI)
    
    
    The same as the above but dispatching on handler (classic
    SSI behaviour; .shtml files get processed).
    
    FilterProvider SSI INCLUDES "%{HANDLER} = 'server-parsed'"
FilterChain SSI
    

    
    

    
    Emulating mod_gzip with mod_deflate
    
    
    Insert INFLATE filter only if "gzip" is NOT in the
    Accept-Encoding header.  This filter runs with ftype CONTENT_SET.
    
    FilterDeclare gzip CONTENT_SET
FilterProvider gzip inflate "%{req:Accept-Encoding} !~ /gzip/"
FilterChain gzip
    

    
    

    
    Image Downsampling
    
    
    Suppose we want to downsample all web images, and have filters
    for GIF, JPEG and PNG.
    
    FilterProvider unpack jpeg_unpack "%{CONTENT_TYPE} = 'image/jpeg'"
FilterProvider unpack gif_unpack  "%{CONTENT_TYPE} = 'image/gif'"
FilterProvider unpack png_unpack  "%{CONTENT_TYPE} = 'image/png'"

FilterProvider downsample downsample_filter "%{CONTENT_TYPE} = m|^image/(jpeg|gif|png)|"
FilterProtocol downsample "change=yes"

FilterProvider repack jpeg_pack "%{CONTENT_TYPE} = 'image/jpeg'"
FilterProvider repack gif_pack  "%{CONTENT_TYPE} = 'image/gif'"
FilterProvider repack png_pack  "%{CONTENT_TYPE} = 'image/png'"
<Location "/image-filter">
    FilterChain unpack downsample repack
</Location>
    

    
    
    
    

    top
    

    

    Protocol Handling
    
    
    Historically, each filter is responsible for ensuring that whatever
    changes it makes are correctly represented in the HTTP response headers,
    and that it does not run when it would make an illegal change.  This
    imposes a burden on filter authors to re-implement some common
    functionality in every filter:
    

    
      
    
    • Many filters will change the content, invalidating existing content
    tags, checksums, hashes, and lengths.
      • 

    
    • Filters that require an entire, unbroken response in input need to
    ensure they don't get byteranges from a backend.
      • 

    
    • Filters that transform output in a filter need to ensure they don't
    violate a Cache-Control: no-transform header from the
    backend.
      • 

    
    • Filters may make responses uncacheable.
      • 
    
    

    
    mod_filter aims to offer generic handling of these
    details of filter implementation, reducing the complexity required of
    content filter modules. This is work-in-progress; the
    FilterProtocol implements
    some of this functionality for back-compatibility with Apache 2.0
    modules.  For httpd 2.1 and later, the
    ap_register_output_filter_protocol and
    ap_filter_protocol API enables filter modules to
    declare their own behaviour.
    

    
    At the same time, mod_filter should not interfere
    with a filter that wants to handle all aspects of the protocol.  By
    default (i.e. in the absence of any FilterProtocol directives), mod_filter
    will leave the headers untouched.
    

    
    At the time of writing, this feature is largely untested,
    as modules in common use are designed to work with 2.0.
    Modules using it should test it carefully.

    AddOutputFilterByType Directive

    Status:Base
    

    Module:mod_filter
    

    Compatibility:Had severe limitations before
being moved to mod_filter in version 2.3.7
    

    
    
    This directive activates a particular output filter for a request depending on the
    response media-type.
    

    
    The following example uses the DEFLATE filter, which
    is provided by mod_deflate. It will compress all
    output (either static or dynamic) which is labeled as
    text/html or text/plain before it is sent
    to the client.
    

    
    AddOutputFilterByType DEFLATE text/html text/plain
    


    
    If you want the content to be processed by more than one filter, their
    names have to be separated by semicolons. It's also possible to use one
    AddOutputFilterByType directive for each of
    these filters.
    

    
    The configuration below causes all script output labeled as
    text/html to be processed at first by the
    INCLUDES filter and then by the DEFLATE
    filter.
    

    
    <Location "/cgi-bin/">
    Options Includes
    AddOutputFilterByType INCLUDES;DEFLATE text/html

    Module:mod_filter
    

    
    
    This directive declares an output filter together with a
    header or environment variable that will determine runtime
    configuration.  The first argument is a filter-name
    for use in FilterProvider,
    FilterChain and
    FilterProtocol directives.
    

    
    The final (optional) argument
    is the type of filter, and takes values of ap_filter_type
    - namely RESOURCE (the default), CONTENT_SET,
    PROTOCOL, TRANSCODE, CONNECTION
    or NETWORK.

    FilterProtocol Directive
    

    

    Description:Deal with correct HTTP protocol handling
    

    Syntax:FilterProtocol filter-name [provider-name]
    proto-flags
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Base
    

    Module:mod_filter
    

    
    
    This directs mod_filter to deal with ensuring the
    filter doesn't run when it shouldn't, and that the HTTP response
    headers are correctly set taking into account the effects of the
    filter.
    

    
    There are two forms of this directive.  With three arguments, it
    applies specifically to a filter-name and a
    provider-name for that filter.
    With two arguments it applies to a filter-name whenever the
    filter runs any provider.
    

    
    Flags specified with this directive are merged with the flags 
    that underlying providers may have registered with 
    mod_filter. For example, a filter may internally specify
    the equivalent of change=yes, but a particular 
    configuration of the module can override with change=no.
    
    

    
    proto-flags is one or more of
    

    
    
    
    change=yes|no
    
    
    Specifies whether the filter changes the content, including possibly 
    the content length.  The "no" argument is supported in 2.4.7 and later.
    

    
    change=1:1
    
    
    The filter changes the content, but will not change the content
    length
    

    
    byteranges=no
    
    
    The filter cannot work on byteranges and requires complete input
    

    
    proxy=no
    
    
    The filter should not run in a proxy context
    

    
    proxy=transform
    
    
    The filter transforms the response in a manner incompatible with
    the HTTP Cache-Control: no-transform header.
    

    
    cache=no
    
    
    The filter renders the output uncacheable (eg by introducing randomised
    content changes)

    Module:mod_filter
    

    
    
    This directive registers a provider for the smart filter.
    The provider will be called if and only if the expression
    declared evaluates to true when the harness is first called.
    

    
    
    provider-name must have been registered by loading
    a module that registers the name with
    ap_register_output_filter.
    
    

    
    expression is an
    ap_expr.

    FilterTrace Directive
    

    

    Description:Get debug/diagnostic information from

    Syntax:FilterTrace filter-name level
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_filter
    

    
    
    This directive generates debug information from
    mod_filter.
    It is designed to help test and debug providers (filter modules), although
    it may also help with mod_filter itself.
    

    
    The debug output depends on the level set:
    
    
    
    
    0 (default)
    
    
    No debug information is generated.
    

    
    1
    
    
    mod_filter will record buckets and brigades
    passing through the filter to the error log, before the provider has
    processed them. This is similar to the information generated by
    mod_diagnostics.
    
    

    
    2 (not yet implemented)
    
    
    Will dump the full data passing through to a tempfile before the
    provider. For single-user debug only; this will not
    support concurrent hits.

    Source File:mod_watchdog.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    


    mod_watchdog defines programmatic hooks for other modules to
periodically run tasks.  These modules can register handlers for
mod_watchdog hooks.  Currently, the following modules in the
Apache distribution use this functionality:
    


    
To allow a module to use mod_watchdog functionality,
mod_watchdog itself must be statically linked to the server
core or, if a dynamic module, be loaded before the calling module.

    Module Apache mod_heartbeat
    

    

    Langues Disponibles:  en  |

    Description:Envoie des messages d'état au mandataire frontal
    

    Statut:Expérimental
    

    Identificateur de Module:heartbeat_module
    

    Fichier Source:mod_heartbeat
    

    Compatibilité:Disponible à partir de la version 2.3
du serveur HTTP Apache
    

    Sommaire
    

    
    mod_heartbeat envoie à un moniteur
    mod_heartmonitor des messages multicast l'informant
    du nombre de connexions courantes. En général,
    mod_heartmonitor est chargé sur un serveur
    mandataire où mod_lbmethod_heartbeat est chargé, ce
    qui permet d'utiliser la lbmethod "heartbeat" au sein des
    directives ProxyPass.
    

    
    
    Le module mod_heartbeat est chargé sur le
    serveur d'origine qui sert les requêtes via le
    serveur mandataire.

    

    
    
        Pour utiliser mod_heartbeat,
	mod_status et mod_watchdog
	doivent être soit des modules statiques, soit des modules
	dynamiques, et dans ce dernier cas, ils doivent être chargés
	avant mod_heartbeat.
    
    


    


    top
    

    

    Utilisation de la sortie de mod_heartbeat
    
    
  
    
      Chaque seconde, ce module génère un paquet multicast UDP contenant
      le nombre de threads/processus occupés et en attente. Le paquet
      possède un format ASCII simple similaire aux paramètres de requête
      GET en HTTP.
  
    


    Exemple de paquet
    
v=1&ready=75&busy=0

    

  
    
    Les utilisateurs disposeront dans le futur de nouvelles variables en
    plus de busy et ready, et toujours séparées par des '&'.

    Statut:Expérimental
    

    Module:mod_heartbeat
    

    
    
    La directive HeartbeatAddress permet de
    spécifier l'adresse multicast à laquelle mod_heartbeat va
    envoyer ses informations. En général, cette adresse correspond à la
    valeur définie par la directive  HeartbeatListen sur le serveur
    mandataire frontal.
    
    
    HeartbeatAddress 239.0.0.1:27999

    ソースファイル:mod_dav_fs.c
    

    概要
    

    
    このモジュールは mod_dav
    のサービスを必要とします。mod_dav
    のサポートモジュールとして動作し、サーバファイルシステム上に
    位置するリソースへのアクセスを提供します。このプロバイダの正式な名前は
    filesystem です。mod_dav
    バックエンドプロバイダは Dav
    ディレクティブを使用して起動されます。
    

    
    例
    
      Dav filesystem
    
    

    
    filesystem は mod_dav
    のデフォルトプロバイダになっていますから、代わりに単に
    On と指定することもできます。

    モジュール識別子:log_config_module
    

    ソースファイル:mod_log_config.c
    

    概要
    

    
    
    このモジュールはクライアントのリクエストを柔軟にログ収集する機能を
    提供します。ログはカスタマイズ可能な書式で書かれ、ファイルに直接
    書いたり、外部プログラムに渡したりすることができます。個々のリクエストを
    特徴に応じてログに書いたり書かなかったりできるように、条件による
    ログ収集も提供されています。
    

    
    このモジュールは三つのディレクティブ提供します:
    ログファイルを作成するための TransferLog,
    新しい書式を 定義する LogFormat,
    ログファイルと 書式を一度に定義する CustomLog です。
    各リクエストが複数回ログ収集されるようにするために
    TransferLog ディレクティブと
    CustomLog
    ディレクティブは複数回使用することができます。
    

    


    top
    

    

    カスタムログ書式
    

    
    LogFormat ディレクティブと
    CustomLog
    ディレクティブの書式を指定する引数は文字列です。この文字列を使ってそれぞれの
    リクエストがログファイルにログ収集されます。その文字列には
    ログファイルにそのまま
    書かれる文字列や、それぞれ改行とタブを表す C 言語
    形式の制御文字 "\n" と "\t"
    とを含めることができます。そのまま出力させたい引用符とバックスラッシュは
    バックスラッシュでエスケープする必要があります。
    

    
    リクエストの特徴そのものは "%"
    ディレクティブを書式の文字列に書くことで
    ログ収集されます。"%"
    ディレクティブはログファイル中では以下のような
    値で置換されます:

        これを使用するためには mod_logio が必要
    

    %O
        ヘッダを含む、送信したバイト数。0 にはならない。
        これを使用するためには mod_logio が必要
    

    

    
    修飾子
    

      
    特定の要素は "%" の直後に HTTP ステータスコードをカンマ区切りで
      指定することで、表示を制限することができます。例えば 
      "%400,501{User-agent}i" では、
      400 と 500 番エラーでのみ User-agent をログします。
      他のステータスコードでは "-" という文字列が
      ログされます。ステータスコードのリストは "!" 
      で否定を指定することができます :
      "%!200,304,302{Referer}i" は、指定された
      3 つのコードのどれにも該当しないリクエスト全てで
      Referer をログします。
    

      
    修飾子 "<" と ">" は内部リダイレクトされたリクエストのログに
      元のリクエストか最終的なリクエストのどちらを使用するかを
      指定するために使います。デフォルトでは、% ディレクティブの
      %s, %U, %T, %D, %r は元のリクエストを、他は最終的なリクエストを
      使用します。例えば、リクエストの最終ステータスを記録するには
      %>s を、内部的に認証されていないリソースへリダイレクトされた
      リクエストで元のリクエストで認証されたユーザを記録するためには
      %<u を使うことができます。
    

    

    
    その他注意点
    

      
    セキュリティ上の理由により 2.0.46 より、
      %r, %i, %o に入っている、
      印字不可能な文字と他の特別な文字は、\xhh 
      という形式の文字列でエスケープされるようになりました。hh は
      そのままのバイトの値の 16 進での値です。この規則の例外には、
      バックスラッシュを使ってエスケープされる " と \ と、
      C 形式の表記法が使われる空白文字 (\n, \t など)
      があります。2.0.46 以前のバージョンではエスケープ処理は行われませんので、
      生ログファイルを扱う際に注意が必要です。
    

      
    httpd 2.0 では 1.3 とは異なり、%b と %B
      フォーマット文字列はクライアントに送信されたバイト数そのものではなく、
      HTTP レスポンスのバイト数です (これらは異なるもので、たとえば、
      コネクションが途中で破棄された場合や、SSL 使用時に一致しません) 。
      mod_logio で提供されている %O
      フォーマット文字列で、ネットワーク経由で実際に転送されたバイト数を
      記録できます。
    

    

    
    例
    

      
    よく使われるフォーマット文字列は:
    

      
    
        
    Common Log Format (CLF)
    
        
    "%h %l %u %t \"%r\" %>s %b"
    

        
    バーチャルホスト付き Common Log Format
    
        
    "%v %h %l %u %t \"%r\" %>s %b"
    

        
    NCSA extended/combined ログ書式
    
        
    "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
        \"%{User-agent}i\""
    

        
    Referer ログ書式
    
        
    "%{Referer}i -> %U"
    

        
    Agent (ブラウザ) ログ書式
    
        
    "%{User-agent}i"

    BufferedLogs ディレクティブ
    

    

    説明:ディスクに書き出す前にメモリにログエントリをバッファする

    デフォルト:BufferedLogs Off
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:Base
    

    モジュール:mod_log_config
    

    互換性:2.0.41 以降
    

    
    
    BufferedLogs ディレクティブを使うと
    mod_log_config の挙動が変化して、
    複数のログを書き出す際に、それぞれのリクエスト処理後毎に
    書き出すのではなく、いったんメモリに蓄えてから、
    まとめてディスクに書き出すようになります。
    この結果ディスクアクセスがより効率的になり、
    高いパフォーマンスの得られるシステムもあるでしょう。
    このディレクティブはサーバ全体で一度だけ設定できます; 
    バーチャルホストごとに設定することはできません。
    

    
    このディレクティブは実験的なものですので、
    使用する際は注意してください。

    CustomLog ディレクティブ
    

    

    説明:ログファイルの名前と書式を設定する
    

    構文:CustomLog  file|pipe
format|nickname
[env=[!]environment-variable]
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_log_config
    

    
    
    CustomLog ディレクティブはサーバへのリクエストを
    ログ収集するために使われます。ログの書式が指定され、
    環境変数を使ってロギングが条件に応じて行なわれるようにすることもできます。
    

    
    ログが書かれる場所を指定する最初の引数は以下の二つの形式の値を
    とることができます:
    

    
    
      
    file
    
      
    ServerRoot
      からの相対パスで表されるファイル名。
    

      
    pipe
    
      
    パイプ文字 "|" と、その後に標準入力からログの
      情報を受けとるプログラムへのパスが続いたもの。

      
    セキュリティ
    
      
    もしプログラムが使用された場合、
      httpd が起動されたユーザとして実行されます。これはサーバが
      root によって起動された場合は root になります。プログラムが
      安全であるように留意してください。
    
      
    
      
    注
    
        
    Unix でないプラットフォームでファイルのパスを入力しているときは、
        使用しているプラットフォームがバックスラッシュの使用を許可していた
        として、通常のスラッシュだけを使うように気をつけてください。
        一般的に、設定ファイル中では常に普通のスラッシュのみを使うようにする
        方が良いです。
    
      
    
    
    

    
    二つめの引数はログファイルに何が書かれるかを指定します。
    前にある LogFormat ディレクティブにより
    定義された nickname か、ログの書式
    のところで説明されている、明示的な format 文字列の
    どちらかを指定することができます。
    

    
    例えば、以下の二つのディレクティブ群は全く同じ効果をもたらします:
    

    
    
      # CustomLog with format nickname
    
      LogFormat "%h %l %u %t \"%r\" %>s %b" common
    
      CustomLog logs/access_log common
    
      
    
      # CustomLog with explicit format string
    
      CustomLog logs/access_log "%h %l %u %t \"%r\" %>s %b"
    
    

    
    三つ目の引数は省略可能で、サーバの環境にある変数があるかないかに
    応じてリクエストをログ収集するかどうかを制御するために使うことができます。
    指定された環境変数がリクエストに対して
    設定されていた場合 ('env=!name' 文が使われたときは
    設定されていない場合)、リクエストがログ収集されます。
    

    
    環境変数は mod_setenvif モジュールと
    mod_rewrite モジュールの両方もしくは
    片方を用いてリクエストごとに設定することができます。
    例えば、サーバにあるすべての GIF 画像へのリクエストを別のログファイル
    には記録したいけれど、メインログには記録したくない、というときは
    以下のものを使うことができます:
    
    
    
    
      SetEnvIf Request_URI \.gif$ gif-image
    
      CustomLog gif-requests.log common env=gif-image
    
      CustomLog nongif-requests.log common env=!gif-image
    
    

    
    古い RefererIgnore ディレクティブと同じ挙動をさせたい場合は、
    次のようにします:
    

    
    
    SetEnvIf Referer example\.com localreferer
    
    CustomLog referer.log referer env=!localreferer

    LogFormat ディレクティブ
    

    

    説明:ログファイルで使用する書式を設定する
    

    構文:LogFormat format|nickname
[nickname]
    

    デフォルト:LogFormat "%h %l %u %t \"%r\" %>s %b"
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_log_config
    

    
    
    このディレクティブはアクセスログファイルの書式を指定します。
    

    
    LogFormat ディレクティブは二つの形式のどちらかを
    とることができます。最初の形式では一つの引数のみが指定され、
    続く TransferLog
    で指定されたログで使われるログの書式を設定します。この単独の引数では
    上のカスタムログ書式で説明されているように
    format を明示的に指定することができます。
    もしくは、下で説明されているように前に LogFormat
    ディレクティブで定義されたログの書式を nicknameを使って
    参照することもできます。
    

    
    LogFormat ディレクティブの二つめの形式は
    format に nickname を与えます。
    フォーマット文字列全体を再び書くかわりに、
    この nickname を続きの LogFormat ディレクティブや
    CustomLog ディレクティブで使うことができます。
    Nickname を定義する LogFormat ディレクティブは
    他には何もしません -- すなわち、ニックネームを定義
    するだけで、実際に書式を適用してデフォルトにするということは行ないません。
    ですから、これは続く TransferLog
    ディレクティブには影響を与えません。
    さらに、LogFormat ディレクティブは既存の nickname を
    使って別の nickname を定義することはできません。Nickname には
    パーセント記号 (%) が含まれていてはいけないことにも注意
    してください。
    

    
    例
    
      LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost_common
    
    


    

    top
    

    TransferLog ディレクティブ
    

    

    説明:ログファイルの位置を指定
    

    構文:TransferLog file|pipe
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_log_config
    

    
    
    このディレクティブは、ログ書式を直接指定できないことと、
    条件付きロギングが無いことを除くと、CustomLog と全く同じ引数と効果があります。
    直接ログ書式を指定する代わりに、ログの書式はそこまでで一番最後に指定された
    ニックネームを定義しない
    LogFormat ディレクティブ
	で定義されたものを使います。
    もし他の書式が全く指定されていないときは Common Log Format
    が使われます。
    

    
    例
    
      LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""
    
      TransferLog logs/access_log

    Le document de référence rapide des directives montre l'usage,
    les valeurs par défaut, le statut,
    et le contexte de chaque directive de configuration d'Apache.  Pour plus
    d'informations sur chacun de ces termes, voir le Dictionnaire des directives.
    

    
    La première colonne donne le nom de la directive et son usage.
    Si la directive possède une valeur par défaut, elle est indiquée dans la
    deuxième colonne.
    Si la valeur par défaut est trop grande pour pouvoir être affichée,
    elle sera tronquée et suivie d'un "+".
    

    
    La troisième colonne énumère les contextes dans
    lesquels la directive est applicable, et la quatrième indique son statut en accord avec le
    tableau des légendes ci-dessous.

    Description:Allows a FastCGI authorizer application to handle Apache
httpd authentication and authorization
    

    Status:Extension
    

    Module Identifier:authnz_fcgi_module
    

    Source File:mod_authnz_fcgi.c
    

    Compatibility:Available in version 2.4.10 and later
    

    Summary
    

    
    This module allows FastCGI authorizer applications to
    authenticate users and authorize access to resources.  It supports
    generic FastCGI authorizers which participate in a single phase
    for authentication and authorization as well as Apache httpd-specific
    authenticators and authorizors which participate in one or both
    phases.
    

    
    FastCGI authorizers can authenticate using user id and password, 
    such as for Basic authentication, or can authenticate using arbitrary
    mechanisms.
    

    


    top
    

    

    Invocation modes
    

    
    The invocation modes for FastCGI authorizers supported by this 
    module are distinguished by two characteristics, type and
    auth mechanism.
    

    
    Type is simply authn for authentication,
    authz for authorization, or authnz for
    combined authentication and authorization.
    

    
    Auth mechanism refers to the Apache httpd configuration
    mechanisms and processing phases, and can be 
    AuthBasicProvider, Require, or 
    check_user_id.  The first two of these
    correspond to the directives used to enable participation in the
    appropriate processing phase.
    

    
    Descriptions of each mode:
    

    
    
      
    Type authn, mechanism
      AuthBasicProvider
    

      
    In this mode, 
      FCGI_ROLE is set to AUTHORIZER and
      FCGI_APACHE_ROLE is set to AUTHENTICATOR.
      The application must be defined as provider type authn
      using 
      AuthnzFcgiDefineProvider and enabled with
      AuthBasicProvider.
      When invoked, the application is
      expected to authenticate the client using the provided user id and
      password.  Example application:


    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHENTICATOR";
    die if $ENV{'FCGI_ROLE'}        ne "AUTHORIZER";
    die if !$ENV{'REMOTE_PASSWD'};
    die if !$ENV{'REMOTE_USER'};

    print STDERR "This text is written to the web server error log.\n";

    if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &&
        $ENV{'REMOTE_PASSWD'} eq "bar" ) {
        print "Status: 200\n";
        print "Variable-AUTHN_1: authn_01\n";
        print "Variable-AUTHN_2: authn_02\n";
        print "\n";
    }
    else {
        print "Status: 401\n\n";
    }
}
    


      Example configuration:

    AuthnzFcgiDefineProvider authn FooAuthn fcgi://localhost:10102/
<Location "/protected/">
  AuthType Basic
  AuthName "Restricted"
  AuthBasicProvider FooAuthn
  Require ...
</Location>
    

      
    

      
    Type authz, mechanism
      Require
    
      
    In this mode, FCGI_ROLE is set to 
      AUTHORIZER and FCGI_APACHE_ROLE is set to
      AUTHORIZER.  The application must be defined as
      provider type authz using 
      AuthnzFcgiDefineProvider.  When invoked, the application 
      is expected to authorize the client using the provided user id and other
      request data.  Example application:

    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHORIZER";
    die if $ENV{'FCGI_ROLE'}        ne "AUTHORIZER";
    die if $ENV{'REMOTE_PASSWD'};

    print STDERR "This text is written to the web server error log.\n";

    if ($ENV{'REMOTE_USER'} eq "foo1") {
        print "Status: 200\n";
        print "Variable-AUTHZ_1: authz_01\n";
        print "Variable-AUTHZ_2: authz_02\n";
        print "\n";
    }
    else {
        print "Status: 403\n\n";
    }
}
    


      Example configuration:

    AuthnzFcgiDefineProvider authz FooAuthz fcgi://localhost:10103/
<Location "/protected/">
  AuthType ...
  AuthName ...
  AuthBasicProvider ...
  Require FooAuthz
</Location>
    

      
    

      
    Type authnz, mechanism
      AuthBasicProvider + Require
    

      
    In this mode, which supports the web server-agnostic FastCGI
      AUTHORIZER protocol, FCGI_ROLE is set to
      AUTHORIZER and FCGI_APACHE_ROLE is not set.
      The application must be defined as provider type authnz
      using 
      AuthnzFcgiDefineProvider.  The application is expected to
      handle both authentication and authorization in the same invocation
      using the user id, password, and other request data.  The invocation 
      occurs during the Apache httpd API authentication phase.  If the 
      application returns 200 and the same provider is invoked during the
      authorization phase (via Require), mod_authnz_fcgi
      will return success for the authorization phase without invoking the
      application.  Example application:

    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'};
    die if $ENV{'FCGI_ROLE'} ne "AUTHORIZER";
    die if !$ENV{'REMOTE_PASSWD'};
    die if !$ENV{'REMOTE_USER'};

    print STDERR "This text is written to the web server error log.\n";

    if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &&
        $ENV{'REMOTE_PASSWD'} eq "bar" &&
        $ENV{'REQUEST_URI'} =~ m%/bar/.*%) {
        print "Status: 200\n";
        print "Variable-AUTHNZ_1: authnz_01\n";
        print "Variable-AUTHNZ_2: authnz_02\n";
        print "\n";
    }
    else {
        print "Status: 401\n\n";
    }
}
    


      Example configuration:

    AuthnzFcgiDefineProvider authnz FooAuthnz fcgi://localhost:10103/
<Location "/protected/">
  AuthType Basic
  AuthName "Restricted"
  AuthBasicProvider FooAuthnz
  Require FooAuthnz
</Location>
    

      
    

      
    Type authn, mechanism
      check_user_id
    

      
    In this mode, FCGI_ROLE is set to 
      AUTHORIZER and FCGI_APACHE_ROLE is set to
      AUTHENTICATOR.  The application must be defined as
      provider type authn using 
      AuthnzFcgiDefineProvider.  AuthnzFcgiCheckAuthnProvider
      specifies when it is called.  Example application:

    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHENTICATOR";
    die if $ENV{'FCGI_ROLE'} ne "AUTHORIZER";

    # This authorizer assumes that the RequireBasicAuth option of 
    # AuthnzFcgiCheckAuthnProvider is On:
    die if !$ENV{'REMOTE_PASSWD'};
    die if !$ENV{'REMOTE_USER'};

    print STDERR "This text is written to the web server error log.\n";

    if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &&
        $ENV{'REMOTE_PASSWD'} eq "bar" ) {
        print "Status: 200\n";
        print "Variable-AUTHNZ_1: authnz_01\n";
        print "Variable-AUTHNZ_2: authnz_02\n";
        print "\n";
    }
    else {
        print "Status: 401\n\n";
        # If a response body is written here, it will be returned to
        # the client.
    }
}
    


      Example configuration:

    AuthnzFcgiDefineProvider authn FooAuthn fcgi://localhost:10103/
<Location "/protected/">
  AuthType ...
  AuthName ...
  AuthnzFcgiCheckAuthnProvider FooAuthn \
                               Authoritative On \
                               RequireBasicAuth Off \
                               UserExpr "%{reqenv:REMOTE_USER}"
  Require ...

    top
    

    

    Additional examples
    

  
      
    
    1. If your application supports the separate authentication and
    authorization roles (AUTHENTICATOR and AUTHORIZER), define 
    separate providers as follows, even if they map to the same
    application:


      AuthnzFcgiDefineProvider authn  FooAuthn  fcgi://localhost:10102/
AuthnzFcgiDefineProvider authz  FooAuthz  fcgi://localhost:10102/
      


    Specify the authn provider on 
    AuthBasicProvider
    and the authz provider on
    Require:


      AuthType Basic
AuthName "Restricted"
AuthBasicProvider FooAuthn
Require FooAuthz
      

    
      2. 

    
    2. If your application supports the generic AUTHORIZER role 
    (authentication and authorizer in one invocation), define a
    single provider as follows:


      AuthnzFcgiDefineProvider authnz FooAuthnz fcgi://localhost:10103/
      


    Specify the authnz provider on both AuthBasicProvider
    and Require:


      AuthType Basic
AuthName "Restricted"
AuthBasicProvider FooAuthnz
Require FooAuthnz
      

    
      3.

    Limitations
    

    
    The following are potential features which are not currently
    implemented:
    

    
    
      
    Apache httpd access checker
    
      
    The Apache httpd API access check phase is a separate
      phase from authentication and authorization.  Some other FastCGI
      implementations implement this phase, which is denoted by the 
      setting of FCGI_APACHE_ROLE to ACCESS_CHECKER.
    

      
    Local (Unix) sockets or pipes
    
      
    Only TCP sockets are currently supported.
    

      
    Support for mod_authn_socache
    
      
    mod_authn_socache interaction should be implemented for
      applications which participate in Apache httpd-style
      authentication.
    

      
    Support for digest authentication using AuthDigestProvider
    
      
    This is expected to be a permanent limitation as there is
      no authorizer flow for retrieving a hash.
    

      
    Application process management
    
      
    This is expected to be permanently out of scope for
      this module.  Application processes must be controlled by
      other means.  For example, fcgistarter can be used to
      start them.
    

      
    AP_AUTH_INTERNAL_PER_URI
    
      
    All providers are currently registered as 
      AP_AUTH_INTERNAL_PER_CONF, which means that checks are not
      performed again for internal subrequests with the same
      access control configuration as the initial request.
    

      
    Protocol data charset conversion
    
      
    If mod_authnz_fcgi runs in an EBCDIC compilation
      environment, all FastCGI protocol data is written in EBCDIC
      and expected to be received in EBCDIC.
    

      
    Multiple requests per connection
    
      
    Currently the connection to the FastCGI authorizer is
      closed after every phase of processing.  For example, if the
      authorizer handles separate authn and authz
      phases then two connections will be used.
    

      
    URI Mapping
    
      
    URIs from clients can't be mapped, such as with the 
      ProxyPass used with FastCGI responders.
    

    
    


    top
    

    

    Logging
    

    
      
        
    1. Processing errors are logged at log level error
        and higher.
      2. 
        
    2. Messages written by the application are logged at log
        level warn.
      3. 
        
    3. General messages for debugging are logged at log level
        debug.
      4. 
        
    4. Environment variables passed to the application are
        logged at log level trace2. The value of the 
        REMOTE_PASSWD variable will be obscured,
        but any other sensitive data will be visible in the 
        log.
      5. 
        
    5. All I/O between the module and the FastCGI application,
        including all environment variables, will be logged in printable
        and hex format at log level trace5.  All
        sensitive data will be visible in the log.
      6. 
    
    

    
    LogLevel can be used
    to configure a log level specific to mod_authnz_fcgi.  For
    example:
    


    LogLevel info authnz_fcgi:trace8

    AuthnzFcgiCheckAuthnProvider Directive
    

    

    Description:Enables a FastCGI application to handle the check_authn
authentication hook.
    

    Syntax:AuthnzFcgiCheckAuthnProvider provider-name|None
option ...
    

    Default:none
    

    Context:directory
    

    Status:Extension
    

    Module:mod_authnz_fcgi
    

    
    
    This directive is used to enable a FastCGI authorizer to
    handle a specific processing phase of authentication or
    authorization.
    

    
    Some capabilities of FastCGI authorizers require enablement
    using this directive instead of
    AuthBasicProvider:
    

    
      
      
    • Non-Basic authentication; generally, determining the user
      id of the client and returning it from the authorizer; see the
      UserExpr option below
      • 
      
    • Selecting a custom response code; for a non-200 response
      from the authorizer, the code from the authorizer will be the
      status of the response
      • 
      
    • Setting the body of a non-200 response; if the authorizer
      provides a response body with a non-200 response, that body
      will be returned to the client; up to 8192 bytes of text are
      supported
      • 
    
    

    
    
      
    provider-name
    
      
    This is the name of a provider defined with 
      AuthnzFcgiDefineProvider.
    

      
    None
    
      
    Specify None to disable a provider enabled
      with this directive in an outer scope, such as in a parent
      directory.
    

      
    option
    
      
    The following options are supported:
      
      
    
         
    Authoritative On|Off (default On)
    
         
    This controls whether or not other modules are allowed
         to run when this module has a FastCGI authorizer configured
         and it fails the request.
    

         
    DefaultUser userid
    
         
    When the authorizer returns success and UserExpr
         is configured and evaluates to an empty string (e.g., authorizer
         didn't return a variable), this value will be used as the user
         id.  This is typically used when the authorizer has a concept of
         guest, or unauthenticated, users and guest users are mapped to
         some specific user id for logging and other purposes.
    

         
    RequireBasicAuth On|Off (default Off)
    
         
    This controls whether or not Basic auth is required
         before passing the request to the authorizer.  If required,
         the authorizer won't be invoked without a user id and
         password; 401 will be returned for a request without that.
    

         
    UserExpr expr (no default)
    
         
    When Basic authentication isn't provided by the client
         and the authorizer determines the user, this expression,
         evaluated after calling the authorizer, determines the
         user.  The expression follows 
         ap_expr syntax and must resolve to a string.  A typical
         use is to reference a Variable-XXX 
         setting returned by the authorizer using an option like
         UserExpr "%{reqenv:XXX}".  If
         this option is specified and the user id can't be retrieved
         using the expression after a successful authentication, the
         request will be rejected with a 500 error.

    AuthnzFcgiDefineProvider Directive
    

    

    Description:Defines a FastCGI application as a provider for
authentication and/or authorization
    

    Syntax:AuthnzFcgiDefineProvider type provider-name
backend-address
    

    Default:none
    

    Context:server config
    

    Status:Extension
    

    Module:mod_authnz_fcgi
    

    
    
    This directive is used to define a FastCGI application as
    a provider for a particular phase of authentication or
    authorization.
    

    
    
      
    type
    
      
    This must be set to authn for authentication,
      authz for authorization, or authnz for
      a generic FastCGI authorizer which performs both checks.
    

      
    provider-name
    
      
    This is used to assign a name to the provider which is
      used in other directives such as 
      AuthBasicProvider
      and 
      Require.
    

      
    backend-address
    
      
    This specifies the address of the application, in the form
      fcgi://hostname:port/.  The application process(es)
      must be managed independently, such as with
      fcgistarter.

    Description:Slot-based shared memory provider.
    

    Status:Extension
    

    Module Identifier:slotmem_shm_module
    

    Source File:mod_slotmem_shm.c
    

    Summary
    

    
    mod_slotmem_shm is a memory provider which
    provides for creation and access to a shared memory segment
    in which the datasets are organized in "slots."
    
    

    
    All shared memory is cleared and cleaned with each
    restart, whether graceful or not. The data itself is
    stored and restored within a file noted by the name
    parameter in the create and attach
    calls. If not specified with an absolute path, the file will be
    created relative to the path specified by the
    DefaultRuntimeDir directive.
    
    

    
    mod_slotmem_shm provides the following API functions:
    
    


    /* call the callback on all worker slots */
apr_status_t doall(ap_slotmem_instance_t *s, ap_slotmem_callback_fn_t *func, void *data, apr_pool_t *pool)

/* create a new slotmem with each item size is item_size. 'name' is used to generate a filename for the persistent
   store of the shared memory if configured. Values are:
      "none"                - Anonymous shared memory and no persistent store
      "file-name"           - [DefaultRuntimeDir]/file-name
      "/absolute-file-name" - Absolute file name */
apr_status_t create(ap_slotmem_instance_t **new, const char *name, apr_size_t item_size, unsigned int item_num, ap_slotmem_type_t type, apr_pool_t *pool)

/* attach to an existing slotmem. See 'create()' for description of 'name' parameter */
apr_status_t attach(ap_slotmem_instance_t **new, const char *name, apr_size_t *item_size, unsigned int *item_num, apr_pool_t *pool)

/* get the direct pointer to the memory associated with this worker slot */
apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void **mem)

/* get/read the memory from this slot to dest */
apr_status_t get(ap_slotmem_instance_t *s, unsigned int item_id, unsigned char *dest, apr_size_t dest_len)

/* put/write the data from src to this slot */
apr_status_t put(ap_slotmem_instance_t *slot, unsigned int item_id, unsigned char *src, apr_size_t src_len)

/* return the total number of slots in the segment */
unsigned int num_slots(ap_slotmem_instance_t *s)

/* return the total data size, in bytes, of a slot in the segment */
apr_size_t slot_size(ap_slotmem_instance_t *s)

/* grab or allocate the first free slot and mark as in-use (does not do any data copying) */
apr_status_t grab(ap_slotmem_instance_t *s, unsigned int *item_id)

/* forced grab or allocate the specified slot and mark as in-use (does not do any data copying) */
apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id)

/* release or free a slot and mark as not in-use (does not do any data copying) */
apr_status_t release(ap_slotmem_instance_t *s, unsigned int item_id)

    Summary
    


    lbmethod=heartbeat uses the services of mod_heartmonitor to balance between origin servers that are providing
heartbeat info via the mod_heartbeat module.
    


     This modules load balancing algorithm favors servers with more ready (idle)
capacity over time, but does not select the server with the most ready capacity
every time.  Servers that have 0 active clients are penalized, with the
assumption that they are not fully initialized.

    Description:Génère automatiquement des index de répertoires d'une
manière similaire à la commande Unix ls, ou à la commande
shell Win32 dir
    

    Statut:Base
    

    Identificateur de Module:autoindex_module
    

    Fichier Source:mod_autoindex.c
    

    Sommaire
    

      
    L'index d'un répertoire peut être généré de deux manières :
    

    
      
      
    • Un fichier situé dans ce répertoire, en général appelé
      index.html, mais dont le nom de ce ou ces fichiers peut être défini par la
      directive DirectoryIndex. C'est le module
      mod_dir qui traite alors cet index.
      • 

      
    • Un listing généré par le serveur, dont le format est contrôlé
      par un certain nombre de directives. Les directives AddIcon, AddIconByEncoding et AddIconByType permettent de
      définir une liste d'icônes à afficher en fonction des différents
      types de fichiers ; pour chaque fichier listé, le premier icône
      qui correspond au type du fichier est affiché. C'est le module
      mod_autoindex qui traite alors cet index.
      • 
    
    
    
    Les deux fonctions sont séparées, si bien que vous pouvez
    entièrement supprimer (ou remplacer) la génération automatique
    d'index, si vous le souhaitez.
    

    
    On active la génération automatique d'index en spécifiant
    Options +Indexes. Voir la directive Options pour plus de détails.
    

    
    Si la directive IndexOptions est spécifiée avec
    l'option FancyIndexing, les en-têtes de colonnes sont des liens
    qui permettent de contrôler l'ordre de tri de l'affichage. Si vous
    actionnez le lien d'un en-tête, le listing sera généré à nouveau,
    trié en fonction des valeurs de la colonne concernée. Si l'on
    actionne de manière répétitive le même en-tête, l'ordre de tri est
    commuté entre les ordres croissant et décroissant. On peut supprimer
    ces liens d'en-têtes de colonnes à l'aide de l'option
    SuppressColumnSorting
    de la directive IndexOptions.
    

    
    Notez que lorsque l'affichage est trié en fonction de la taille,
    c'est la taille réelle qui est prise en compte, et non la
    valeur affichée - ainsi, un fichier de 1010 octets sera toujours
    affiché avant un fichier de 1011 octets (en ordre croissant), même
    si la taille affichée des deux fichiers est "1K".

    Arguments de la requête d'autoindexation
    
    

    
    La chaîne de paramètres de la requête peut contenir de nombreux
    arguments permettant dans une certaine mesure au client de contrôler
    l'ordre de l'index du répertoire, ainsi que la liste des fichiers à
    afficher. Si vous souhaitez désactiver cette fonctionnalité,
    utilisez l'option IndexOptions
    IgnoreClient.
    

    
    Les en-têtes de tri des colonnes eux-mêmes sont des hyper-liens
    auto-référant qui ajoutent les options de tri à la requête énumérées
    ci-dessous qui peuvent être ajoutées à toute requête concernant la
    ressource répertoire.
    

    
      
      
    • C=N trie l'affichage en fonction du nom de
      fichier
      • 

      
    • C=M trie l'affichage en fonction de la date de
      dernière modification, puis du nom de fichier
      • 

      
    • C=S trie l'affichage en fonction de la taille,
      puis du nom de fichier
      • 

      
    • C=D trie l'affichage en fonction
      de la description, puis du nom de fichier
      • 

      
    • O=A trie l'affichage selon l'ordre croissant
      • 

      
    • O=D trie l'affichage selon
      l'ordre décroissant
      • 

      
    • F=0 affiche le listing sous la forme d'une simple
      liste (sans FancyIndex)
      • 

      
    • F=1 affiche le listing avec en-têtes de colonnes
      sous forme de liens hyper-textes (FancyIndexed)
      • 

      
    • F=2 affiche le listing sous
      forme de table HTML avec en-têtes de colonnes contenant des liens
      hyper-textes (FancyIndexed)
      • 

      
    • V=0 désactive le tri en fonction de la
      version
      • 

      
    • V=1 active le tri en fonction de
      la version
      • 

      
    • P=modèle n'affiche que les fichiers
      correspondant au modèle spécifié
      • 
    
    

    
    Notez que l'argument 'P' (pour Pattern) n'est testé
    qu'après que les directives habituelles IndexIgnore ont été traitées,
    et que tous les noms de fichiers sont encore assujettis aux mêmes
    critères que pour tout autre listing auto-indexé. L'interpréteur
    d'arguments de requête de mod_autoindex s'arrête
    immédiatement s'il rencontre une option non reconnue. Les arguments
    de requête doivent être bien formés, selon la table ci-dessus.
    

    
    Les options de requêtes sont illustrées par l'exemple ci-dessous, qui
    peut être copié et collé dans un fichier header.html. Notez que l'argument
    inconnu "X", pour le bouton submit, est introduit en dernier afin de
    s'assurer que tous les arguments ont été interprétés avant que
    mod_autoindex ne rencontre l'entrée X=Go.
    

    
    Exemple
    <form action="" method="get">
    Show me a <select name="F">
        <option value="0"> Plain list</option>
        <option value="1" selected="selected"> Fancy list</option>
        <option value="2"> Table list</option>
    </select>
    Sorted by <select name="C">
        <option value="N" selected="selected"> Name</option>
        <option value="M"> Date Modified</option>
        <option value="S"> Size</option>
        <option value="D"> Description</option>
    </select>
    <select name="O">
        <option value="A" selected="selected"> Ascending</option>
        <option value="D"> Descending</option>
    </select>
    <select name="V">
        <option value="0" selected="selected"> in Normal order</option>
        <option value="1"> in Version order</option>
    </select>
    Matching <input type="text" name="P" value="*" />
    <input type="submit" name="X" value="Go" />
</form>

    La directive AddAlt permet d'afficher un
    texte optionnel pour un fichier, à la place d'un icône, dans le cas
    d'un affichage FancyIndexing.
    fichier est une extension de fichier, un nom de fichier
    partiel, une expression avec caractères génériques ou un nom de
    fichier complet permettant de caractériser le(s) fichier(s)
    concerné(s). Si texte contient des espaces, vous devez
    l'entourer de guillemets ou d'apostrophes (" ou
    '). Ce texte optionnel sera affiché si le client ne
    peut pas afficher d'images, si le chargement d'images est désactivé
    ou si l'icône ne peut pas être trouvé.

    La directive AddAltByEncoding permet
    d'afficher un texte optionnel à la place d'un icône pour un fichier
    dans le cas d'un affichage FancyIndexing.
    codage MIME doit être un type valide, comme
    x-compress. Si texte contient des espaces,
    vous devez l'entourer de guillemets ou d'apostrophes ("
    ou '). Ce texte optionnel sera affiché si le client ne
    peut pas afficher d'images, si le chargement d'images est désactivé
    ou si l'icône ne peut pas être trouvé.

    Directive AddDescription
    

    

    Description:Afficher la description d'un fichier
    

    Syntaxe:AddDescription texte [fichier] ...
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_autoindex
    

    
    
    Cette directive permet d'afficher une description pour un
    fichier, dans le cas d'un affichage FancyIndexing.
    fichier est une extension de fichier, un nom de fichier
    partiel, une expression avec caractères génériques ou un nom de
    fichier complet permettant de caractériser le fichier.
    texte doit être entouré de guillemets
    (").
    

    
    AddDescription "The planet Mars" mars.gif
AddDescription "My friend Marshall" friends/mars.gif
    


    
    La taille par défaut, habituelle du champ de description est de
    23 octets. L'option IndexOptions SuppressIcon ajoute 6 octets, l'option
    IndexOptions
    SuppressSize en ajoute 7 et l'option IndexOptions
    SuppressLastModified en ajoute 19. Ainsi, la plus grande
    taille par défaut qui peut être assignée à la colonne description
    est de 55 octets.
    

    
    Comme l'argument fichier peut être un nom de fichier
    partiel, vous devez garder à l'esprit qu'un nom de fichier partiel
    trop court pourra correspondre à des fichiers non voulus. Par
    exemple, le.html correspondra au fichier
    le.html, mais aussi au fichier
    example.html. En cas d'ambiguïté, utilisez un nom de
    fichier aussi complet que possible, et ordonnez votre liste de
    directives AddDescription en conséquence.
    

    
    Voir le mot-clé DescriptionWidth de la directive IndexOptions pour plus de
    détails sur la manière d'augmenter la taille de cette colonne, ou
    pour permettre des descriptions de taille illimitée.
    

    
    Avertissement
    
      
    Le texte descriptif défini par la directive
      AddDescription peut contenir des marquages
      HTML, comme des balises ou des entités caractères. Si la limite de
      taille de la colonne description venait à tronquer une balise (par
      exemple couper la fin d'une phrase en caractères gras), le
      résultat pourrait en affecter toute la suite du listing du
      répertoire.
    
    
    

    
    Arguments avec chemins
    
      
    Les chemins absolus ne sont actuellement pas supportés et ne
      peuvent correspondre à aucun chemin réel à l'exécution. Les
      arguments contenant des chemins relatifs, qui ne devraient être
      normalement utilisés que dans les fichiers htaccess, sont
      implicitement préfixés par '*/' afin d'éviter toute association
      avec des noms de répertoires partiels.

    La directive HeaderName permet de définir
    le nom du fichier qui sera inséré au début de la page contenant
    l'index. nom fichier est le nom du fichier à inclure.
    

    
    HeaderName HEADER.html
    


    
    
      
    Les deux directives HeaderName et ReadmeName traitent maintenant
      nom fichier comme un chemin URI relatif au chemin
      utilisé pour accéder au répertoire faisant l'objet de l'index. Si
      nom fichier commence par un slash '/', il sera
      considéré comme relatif au répertoire défini par la directive
      DocumentRoot.
    

      
    HeaderName /include/HEADER.html
    


      
    nom fichier doit correspondre à un document dont le
      type MIME est du style text/* (par exemple
      text/html, text/plain, etc...). Cela
      signifie que nom fichier peut faire référence à un
      script CGI si le véritable type MIME du script (et non celui de sa
      sortie) est marqué comme text/html par exemple à
      l'aide d'une directive comme :
    

      
    AddType text/html .cgi
    


      
    Une négociation de
      contenu sera effectuée si Options MultiViews a été
      précisé. Si nom fichier correspond à un document
      statique text/html (et non à un script CGI), et une
      des deux options
      Includes ou IncludesNOEXEC est activée,
      le fichier sera traité en tant qu'inclusion côté serveur (Server
      Side Include) (voir la documentation de
      mod_include).
    
    
    

    
    Si le fichier spécifié par la directive
    HeaderName contient les en-têtes d'un
    document HTML (<html>, <head>, etc...), vous serez
    probablement amenés à définir IndexOptions
    +SuppressHTMLPreamble, de manière à ce que ces balises ne

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_autoindex
    

    
    
    La directive IndexOptions permet de
    spécifier les options de configuration de l'indexation du
    répertoire. option peut prendre l'une des valeurs
    suivantes :
    

    
    
      
    AddAltClass
    
      
    Ajoute une déclaration de classe CSS supplémentaire à chaque
      enregistrement de la table du listing du répertoire dans le cas où
      IndexOptions HTMLTable est activé et où un
      IndexStyleSheet a été défini. Plutôt que d'appliquer
      à chaque enregistrement de la table les classes standards
      even et odd, c'est ici une classe
      even-ALT ou odd-ALT
      qui sera appliquée, où ALT sera soit le texte alternatif
      standard associé au style du fichier (par exemple snd,
      txt, img, etc...), soit le texte alternatif
      défini par une des différentes directives AddAlt*.
      
    


      
    Charset=jeu de caractères
    

      
    Le mot-clé Charset vous permet de spécifier le
      jeu de caractères de la page générée. La valeur par défaut est
      UTF-8 sous Windows et MAC OS X, et
      ISO-8859-1 dans les autres cas (en fait selon que le
      système de fichiers sous-jacent utilise les noms de fichiers en
      Unicode ou non).

      
    IndexOptions Charset=UTF-8
    

      
    

      
    DescriptionWidth=[n | *]
    

      
    Le mot-clé DescriptionWidth vous permet de
      spécifier la taille en caractères de la colonne description.
    

      
    Avec -DescriptionWidth (ou si l'option n'est pas
      définie), mod_autoindex calcule la meilleure
      taille.
    

      
    DescriptionWidth=n fixe la taille de
      la colonne à n octets.
    

      
    DescriptionWidth=* ajuste la taille de la colonne
      à la plus longue chaîne de description.

      Voir la section concernant AddDescription pour les dangers
      inhérants à la troncature des descriptions.
    

      
    FancyIndexing
    

      
    Cette option active l'indexation "améliorée" des répertoires,
      c'est à dire avec en-têtes de colonnes sous forme d'hyper-liens
      auto-référants.
    

      
    FoldersFirst
    

      
    Lorsque cette option est activée, la liste des
      sous-répertoires apparaîtra toujours en premier, suivie
      de la liste des fichiers normaux du répertoire. Le listing
      comporte principalement deux parties, les fichiers et les
      sous-répertoires, chacun d'eux étant trié séparément et les
      sous-répertoires affichés en premier. Par exemple, si l'ordre de
      tri est décroissant par nom, et si FoldersFirst est
      activé, le sous-répertoire Zed sera affiché avant le
      sous-répertoire Beta, qui sera lui-même affiché avant
      les fichiers normaux Gamma et Alpha.
      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

      
    HTMLTable
    

      
    Cette option pour l'affichage
      FancyIndexing permet de construire une table simple
      pour l'affichage de l'index du répertoire. Cette option s'avèrera
      particulièrement nécessaire pour les plates-formes où utf-8 est
      activé et dans le cas où les noms de fichiers ou les chaînes
      de description alternent entre les ordres de lecture gauche à
      droite et droite à gauche.
    

      
    IconsAreLinks
    

      
    Configure la partie réservée aux icônes de l'ancrage pour le
      nom de fichier, dans le cas d'un affichage "amélioré".
    

      
    IconHeight[=pixels]
    

      
    Si cette option est présente, en combinaison avec
      IconWidth, le serveur va inclure les attributs
      height et width dans la balise
      img qui référence le fichier de l'icône. Ceci va
      permettre au navigateur de prévoir les caractéristiques de la page
      sans devoir attendre que toutes les images aient été chargées. En
      l'absence de cette option, c'est la hauteur standard définie par
      le logiciel Apache httpd qui est choisie comme valeur par défaut.

      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

      
    IconWidth[=pixels]
    

      
    Si cette option est présente, en combinaison avec
      IconHeight, le serveur va inclure les attributs
      height et width dans la balise
      img qui référence le fichier de l'icône. Ceci va
      permettre au navigateur de prévoir les caractéristiques de la page
      sans devoir attendre que toutes les images aient été chargées. En
      l'absence de cette option, c'est la largeur standard définie par
      le logiciel Apache httpd qui est choisie comme valeur par défaut.
    

      
    IgnoreCase
    

      
    Si cette option est activée, les noms sont triés sans tenir
      compte de la casse. Par exemple, si le tri s'effectue sur les noms
      dans l'ordre croissant, et si IgnoreCase est activé,
      le fichier Zeta apparaîtra après le fichier alfa (Note : le
      fichier GAMMA apparaîtra toujours avant le fichier gamma).
      
    

      
    IgnoreClient
    

      
    Si cette option est activée, mod_autoindex va
      ignorer toutes les variables de requête fournies par le client, y
      compris les informations de tri (ce qui implique l'activation de
      l'option SuppressColumnSorting).
    

      
    NameWidth=[n
               | *]
    

      
    Le mot-clé NameWidth vous permet de spécifier la
      largeur en octets de la colonne correspondant au nom du
      fichier.
    

      
    Avec -NameWidth (ou si l'option n'est pas
      définie), mod_autoindex va calculer la meilleure largeur
      possible, mais jusqu'à une largeur maximale de 20 octets.
    

      
    NameWidth=n fixe la largeur de la
      colonne à n octets.
    

      
    NameWidth=* définit la largeur de colonne à la
      valeur nécessaire.
    

      
    ScanHTMLTitles
    

      
    L'activation de cette option permet d'extraire le titre des
      documents HTML dans le cas d'un affichage "amélioré". Si le fichier
      ne possède aucune description définie par la directive AddDescription, httpd va lire
      le document pour tenter d'en extraire le titre. Ce
      processus est coûteux en ressources disque et CPU.
    

      
    ShowForbidden
    

      
    Si cette option est activée, Apache httpd affichera les fichiers
      normalement cachés suite au retour des valeurs
      HTTP_UNAUTHORIZED ou HTTP_FORBIDDEN par
      la sous-requête.
    

      
    SuppressColumnSorting
    

      
    Si cette option est activée, Apache httpd supprimera les liens
      hyper-texte dans les en-têtes de colonnes dans le cas d'un
      affichage "amélioré". Par défaut, ces en-têtes constituent des liens
      hyper-texte, et la sélection de l'un d'entre eux va trier l'index
      du répertoire en fonction des valeurs de la colonne
      correspondante. Cependant, les arguments de la chaîne de
      paramètres de la requête ajoutés à l'URL seront toujours ignorés.
      Ce comportement est contrôlé par l'option IndexOptions
      IgnoreClient.
    

      
    SuppressDescription
    

      
    L'activation de cette option va supprimer la description des
      fichiers dans le cas d'un affichage "amélioré". Par défaut aucune
      description de fichier n'est définie, et par conséquent
      l'utilisation de cette option va permettre de récupérer un espace
      à l'écran de 23 caractères pouvant être utilisé pour autre chose.
      Voir la directive AddDescription pour plus d'informations à propos de
      la définition des descriptions de fichiers. Voir aussi l'option
      d'index DescriptionWidth
      pour limiter la taille de la colonne description.

      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

      
    SuppressHTMLPreamble
    

      
    Si le répertoire contient effectivement le fichier spécifié
      par la directive HeaderName, le module inclut
      en général le contenu du fichier après avoir inséré un préambule
      HTML standard (<html>,
      <head>, etc...). L'activation de
      l'option SuppressHTMLPreamble supprime l'insertion de
      ce préambule, et le module va alors commencer l'affichage
      directement par le contenu du fichier d'en-tête. Dans ce cas par
      contre, le fichier d'en-tête doit contenir des instructions HTML
      appropriées. S'il n'y a pas de fichier d'en-tête, le préambule est
      généré comme dans le cas général. Si vous spécifiez aussi une
      directive ReadmeName, et si ce
      fichier existe, les balises de fermeture closing
      </body></html> seront aussi omises dans la sortie, en
      supposant que vous ayez placé ces balises de fermeture dans ce
      fichier.
    

      
    SuppressIcon
    

      
    L'activation de cette option supprime l'affichage des icônes
      dans le cas d'un affichage "amélioré". La combinaison de
      SuppressIcon et SuppressRules permet de
      générer une sortie au format HTML 3.2 qui, selon les dernières
      spécifications, interdit les éléments img et
      hr dans les blocs pre (utilisés pour
      formater les affichages "améliorés").
    

      
    SuppressLastModified
    

      
    L'activation de cette option supprime l'affichage de la date
      de dernière modification dans le cas d'un affichage "amélioré".

      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

      
    SuppressRules
      
    

      
    L'activation de cette option supprime l'affichage des lignes
      horizontales (éléments hr) dans les index de
      répertoires. La combinaison de
      SuppressIcon et SuppressRules permet de
      générer une sortie au format HTML 3.2 qui, selon les dernières
      spécifications, interdit les éléments img et
      hr dans les blocs pre (utilisés pour
      formater les affichages "améliorés").

      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

      
    SuppressSize
    

      
    L'activation de cette option supprime l'affichage de la taille
      du fichier dans le cas d'un affichage "amélioré".

      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

      
    TrackModified
    

      
    Cette option renvoie les valeurs Last-Modified et
      ETag pour le répertoire indexé dans l'en-tête HTTP.
      Elle n'est valide que si le système d'exploitation et le système
      de fichiers renvoient des résultats appropriés pour la fonction
      stat(). C'est le cas de certains systèmes Unix, ainsi que JFS sous
      OS/2 ou
      les volumes NTFS sous Win32. Ce n'est par contre pas le cas
      des volumes FAT Win32 et OS/2. Lorsque cette option est activée, le
      client ou le mandataire peuvent détecter les changements dans la
      liste des fichiers lorsqu'ils effectuent une requête
      HEAD. Notez que certains systèmes d'exploitation
      détectent correctement les nouveaux fichiers et les fichiers
      supprimés, mais ne détectent pas les modifications de tailles ou
      de dates des fichiers du répertoire. Les modifications de
      taille ou de date d'un fichier existant ne mettent pas à jour
      l'en-tête Last-Modified sur toutes les plate-formes
      Unix. Si c'est le cas, laissez cette option
      désactivée.
    

      
    Type=type MIME
    

      
    Le mot-clé Type vous permet de spécifier le type
      MIME de la page générée. La valeur par défaut est
      text/html.

      
    IndexOptions Type=text/plain
    

      
    

      
    UseOldDateFormat
      (Apache HTTP Server versions 2.4.26 et ultérieures)
    

      
    Le format de date utilisé dans le champ Last Modified
      avait été modifié par inadvertance de "%d-%b-%Y %H:%M" en
      "%Y-%m-%d %H:%M" dans la version 2.4.0. Cette option permet
      de restaurer le format de date des versions 2.2 et antérieures.
    

      
    VersionSort
    

      
    Le mot-clé VersionSort permet de trier les
      fichiers contenant des numéros de version d'une manière
      spécifique. Les chaînes sont triées comme d'habitude, excepté les
      sous-chaînes de chiffres du nom de fichier et de sa description
      qui sont comparées en fonction de leur valeur numérique.

      
    Exemple :
    
        foo-1.7
    
        foo-1.7.2
    
        foo-1.7.12
    
        foo-1.8.2
    
        foo-1.8.2a
    
        foo-1.12
      
    

      
    Si le nombre commence par le chiffre 0, il est considéré comme
      la partie fractionnaire d'un nombre :
    

      
    
        foo-1.001
    
        foo-1.002
    
        foo-1.030
    
        foo-1.04
      
    
      
    

      
    XHTML
    

      
    Le mot-clé XHTML enjoint
      mod_autoindex de générer du code XHTML 1.0 au
      lieu de HTML 3.2.

      Cette option n'a d'effet que si FancyIndexing
      est aussi activé.
      
    

    
    

   
   
    Options d'index incrémentales
    
   
    
     
    Vous devez porter une attention particulière à la manière dont
     les IndexOptions multiples sont traitées.
    

     
      
     
    • Plusieurs directives IndexOptions
     apparaissant dans la même section directory sont maintenant
     fusionnées. Le résultat de :

     
      <Directory "/foo">
    IndexOptions HTMLTable
    IndexOptions SuppressColumnsorting
</Directory>
      


     
      est équivalent à
      

     
      IndexOptions HTMLTable SuppressColumnsorting
      

     
      • 

     
    • L'ajout de la syntaxe incrémentale (en préfixant les mots-clés
     avec + ou -).
      • 
     
    

     
    Chaque fois qu'un mot-clé préfixé par '+' ou '-' est trouvé, il
     est appliqué aux définitions des
     IndexOptions courantes (qui ont été
     éventuellement héritées d'un directory de niveau supérieur). Par
     contre, si un mot-clé non préfixé est trouvé, il supprime toutes
     les definitions héritées, ainsi que toute
     définition incrémentale. Considérons l'exemple
     suivant :
    

     
    IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
IndexOptions +SuppressSize
    


     
    L'effet global est équivalent à l'effet qu'aurait provoqué
     IndexOptions FancyIndexing +SuppressSize, car l'option
     non préfixée FancyIndexing annule les mots-clés
     incrémentaux situés avant elle, mais leur permet ensuite de
     s'incrémenter à nouveau.
    

     
    Pour définir inconditionnellement les
     IndexOptions pour un répertoire particulier,
     tout en supprimant les définitions héritées, spécifiez les
     mots-clés sans préfixe + ou -

    Module:mod_autoindex
    

    
    
    La directive IndexOrderDefault s'utilise
    en combinaison avec l'option d'index FancyIndexing. Par
    défaut, les index de répertoires "améliorés" sont affichés selon l'ordre
    croissant des noms de fichiers ; la directive
    IndexOrderDefault vous permet de modifier ce
    comportement.
    

    
    La directive IndexOrderDefault accepte
    deux arguments. Le premier est soit Ascending, soit
    Descending, et indique l'ordre de tri. Le second doit
    prendre une des valeurs Name, Date,
    Size, ou Description, et permet
    d'identifier la clé primaire. La clé secondaire est
    toujours le nom du fichier selon un ordre croissant.
    

    
    Si vous le désirez, vous pouvez empêcher le client de modifier
    l'ordre de tri de la liste en ajoutant l'option d'index  SuppressColumnSorting
    qui supprime le lien de définition du tri de l'en-tête de la
    colonne, ainsi que l'option IgnoreClient qui
    empêche ce même client de passer outre vos préférences de tri en
    ajoutant manuellement des options de tri à la chaîne de paramètres
    de la requête.

    La directive ReadmeName permet de définir
    le nom du fichier dont le contenu sera ajouté à la fin de l'index.
    nom-fichier est le nom du fichier à inclure, et est
    considéré comme relatif au répertoire faisant l'objet de l'index. Si
    nom-fichier commence par un slash '/', comme dans
    l'exemple 2, il sera considéré
    comme relatif au répertoire défini par la directive DocumentRoot.
    
    

    
    # Example 1
ReadmeName FOOTER.html
    


    
    # Example 2
ReadmeName /include/FOOTER.html

    説明:起動時や再起動時に実行コードとモジュールをサーバにロードする

    

    ステータス:Extension
    

    モジュール識別子:so_module
    

    ソースファイル:mod_so.c
    

    互換性:このモジュールは Window では (常に含まれている) Base
モジュールです
    

    概要
    


    
    いくつかのオペレーティングシステムでは、サーバの再コンパイルをする代わりに、
    このモジュールを使用して
    動的共有オブジェクト
    (DSO) 機構により、実行時に Apache HTTP Server にモジュールを読み込ませることが
    できます。
    

    
    Unix 上では、読み込まれるコードは通常は共有オブジェクトファイル
    (普通 .so という拡張子が付いています) からです。
    Windows 上ではこのモジュールの拡張子は .so か .dll
    です。
    

    
    警告
    
    
    Apache HTTP Server のあるメジャーバージョン向けにビルドされたモジュールは一般に
    他のメジャーバージョンでは動きません。(例えば 1.3 と 2.0、 2.0 と 2.2)
    またメジャーバージョン間ではAPIの変更がしばしば発生し、そのため新しい
    メジャーバージョン向けにモジュールの修正が必要になることがあります。

    Windows 用のロード可能なモジュールを作成する
    

    
    注
    
    
    Windows において動的にロードされるモジュールの拡張子は普通 .dll
    ですが、Apache httpd のモジュールは mod_whatever.so
    といった名前を持ちます。これは、他のプラットフォームでの通常の形式に
    あわせたものです。しかしながら、サードパーティ製モジュール、例えばPHPなど、
    は今でも .dll の拡張子を使っています。
    

    
    まだ mod_so で ApacheModuleFoo.dll という名前の
    モジュールもロードされますが、新しい名前の付け方を使う方が好まれます。
    モジュールを 2.0 用に移植しているのであれば、2.0 の習慣に合うように名前を
    修正してください。
    

    
    Apache httpd のモジュール API は UNIX と Windows 間では変更されていません。
    多くのモジュールは全く変更なし、もしくは簡単な変更により Windows 
    で実行できるようになります。ただし、それ以外の Windows には無い Unix
    アーキテクチャーの機能に依存したモジュールは動作しません。
    

    
    モジュールが実際に動作するときは、
    二つの方法のどちらかでサーバに追加することができます。まず、Unix
    と同様にサーバにコンパイルして組み込むことができます。Windows
    用の Apache httpd は Unix 用の Apache にある Configure
    プログラムがありませんので、モジュールのソースファイルを
    ApacheCore プロジェクトファイルに追加し、シンボルを
    os\win32\modules.c ファイルに追加する必要があります。
    

    
    二つ目はモジュールを DLL としてコンパイルする方法です。
    DLL は共有ライブラリで、実行時に
    LoadModule
    ディレクティブによりサーバに読み込むことができます。これらのモジュール
    DLL はそのまま配布することが可能で、サーバを再コンパイルすることなく、Windows
    用の Apache httpd のすべてのインストールで実行することができます。
    

    
    モジュール DLL を作成するためには、
    モジュールの作成に小さな変更を行なう必要があります。
    つまり、モジュールのレコード (これは後で作成されます。
    以下を参照してください) が DLL からエクスポートされなければなりません。
    これを行なうには、AP_MODULE_DECLARE_DATA (Apache httpd
    のヘッダファイルで定義されています) をモジュールのモジュールレコード
    定義の部分に追加してください。たとえば、モジュールに
    

    
    module foo_module;

    

    
    があるとすると、それを次のもので置き換えてください。
    

    
    module AP_MODULE_DECLARE_DATA foo_module;

    

    
    Unix 上でもこのモジュールを
    変更無しで使い続けられるように、このマクロは Windows
    上でのみ効力を持ちます。.DEF
    ファイルの方を良く知っているという場合は、
    代わりにそれを使ってモジュールレコードを
    エクスポートすることもできます。
    
    
    さあ、あなたのモジュールの DLL を作成しましょう。これを、
    libhttpd.lib 共有ライブラリがコンパイルされたときに作成された
    ibhttpd.lib エクスポートライブラリとリンクしてください。この時に、
    Apache httpd のヘッダファイルが正しい位置にあるように、
    コンパイラの設定を変える必要があるかもしれません。
    このライブラリはサーバルートの modules ディレクトリにあります。
    ビルド環境が正しく設定されるように、既存のモジュール用の .dsp を
    取ってくるのが一番良いでしょう。もしくは、あなたの .dsp と
    コンパイラとリンクのオプションを比較する、というものでも良いです。
    

    
    これで DLL 版のモジュールが作成されているはずです。
    サーバルートの modules
    ディレクトリにモジュールを置いて、
    LoadModule
    ディレクティブを使って読み込んでください。

    モジュール識別子として書かれているものです。例 :
    

   
    LoadModule status_module modules/mod_status.so
    


    
    これは ServerRoot の modules サブディレクトリから指定された名前の
    モジュールをロードします。

    Apache Module mod_authn_dbm

    Description:User authentication using DBM files
    

    Status:Extension
    

    Module Identifier:authn_dbm_module
    

    Source File:mod_authn_dbm.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module provides authentication front-ends such as
    mod_auth_digest and mod_auth_basic
    to authenticate users by looking up users in dbm password
    files. Similar functionality is provided by
    mod_authn_file.
    

    
    When using mod_auth_basic or
    mod_auth_digest, this module is invoked via the
    AuthBasicProvider or
    AuthDigestProvider
    with the dbm value.

    AuthDBMType Directive
    

    

    Description:Sets the type of database file that is used to
store passwords
    

    Syntax:AuthDBMType default|SDBM|GDBM|NDBM|DB
    

    Default:AuthDBMType default
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_dbm
    

    
    
    Sets the type of database file that is used to store the passwords.
    The default database type is determined at compile time. The
    availability of other types of database files also depends on
    compile-time settings.
    

    
    For example, in order to enable the support for Berkeley DB
    (correspondent to the db type) the
    --with-berkeley-db option needs to be added to httpd's
    configure to generate the necessary DSO.
    

    
    It is crucial that whatever program you use to create your password
    files is configured to use the same type of database.

    AuthDBMUserFile Directive
    

    

    Description:Sets the name of a database file containing the list of users and
passwords for authentication
    

    Syntax:AuthDBMUserFile file-path
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_dbm
    

    
    
    The AuthDBMUserFile directive sets the
    name of a DBM file containing the list of users and passwords for
    user authentication. File-path is the absolute path to
    the user file.
    

    
    The user file is keyed on the username. The value for a user is
    the encrypted password, optionally followed by a colon and arbitrary
    data. The colon and the data following it will be ignored by the
    server.
    

    
    Security:
    
      
    Make sure that the AuthDBMUserFile is stored
      outside the document tree of the web-server; do not put it in
      the directory that it protects. Otherwise, clients will be able to
      download the AuthDBMUserFile.
    
    
    

    
    The encrypted password format depends on which authentication
    frontend (e.g. mod_auth_basic or
    mod_auth_digest) is being used.  See Password Formats for
    more information.
    

    
    Important compatibility note: The implementation of
    dbmopen in the Apache modules reads the string length of
    the hashed values from the DBM data structures, rather than relying
    upon the string being NULL-appended. Some applications, such as
    the Netscape web server, rely upon the string being
    NULL-appended, so if you are having trouble using DBM files
    interchangeably between applications this may be a part of the
    problem.
    

    
    A perl script called
    dbmmanage is included with
    Apache. This program can be used to create and update DBM
    format password files for use with this module. Another
    tool for maintaining the DBM files is the included program
    htdbm.

    Algorithme d'attribution des requêtes en attente
    

    

    
    Activé via lbmethod=bybusyness, ce planificateur
    surveille le nombre de requêtes assignées à chaque processus worker
    à l'instant présent. Une nouvelle requête est automatiquement
    assignée au processus worker auquel est assigné le plus petit nombre de
    requêtes. Ceci s'avère utile dans le cas où les
    processus worker mettent en file d'attente les requêtes entrantes
    indépendamment d'Apache, et permet de s'assurer que la longueur des
    files reste raisonnable, et qu'une requête est toujours assignée au
    processus worker qui sera à même de la servir le plus
    rapidement et avec une latence réduite.
    

    
    Si plusieurs processus worker s'avèrent les moins chargés, le
    choix d'un de ces derniers est effectué à partir des statistiques
    (et des estimations de charges) qu'utilise la méthode de décompte
    des requêtes. Au fil du temps, la distribution des tâches finit par
    ressembler à celle de byrequests (tel qu'implémenté par
    mod_lbmethod_byrequests).

    Description:mod_proxy extension for load balancing 
    

    Status:Extension
    

    Module Identifier:proxy_balancer_module
    

    Source File:mod_proxy_balancer.c
    

    Compatibility:Available in version 2.1 and later
    

    Summary
    

    
    This module requires the service of mod_proxy and it provides load balancing for
    all the supported protocols. The most important ones are:
    
    
    
    
    The Load balancing scheduler algorithm is not provided by this
    module but from other ones such as:
    
    

    
    Thus, in order to get the ability of load balancing,
    mod_proxy, mod_proxy_balancer
    and at least one of load balancing scheduler algorithm modules have
    to be present in the server.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.
    
    
    

    


    top
    

    

    Load balancer scheduler algorithm
    
    
    
    At present, there are 4 load balancer scheduler algorithms available
    for use: Request Counting (mod_lbmethod_byrequests),
    Weighted Traffic Counting (mod_lbmethod_bytraffic),
    Pending Request Counting (mod_lbmethod_bybusyness) and
    Heartbeat Traffic Counting (mod_lbmethod_heartbeat).
    These are controlled via the lbmethod value of
    the Balancer definition. See the ProxyPass
    directive for more information, especially regarding how to
    configure the Balancer and BalancerMembers.
    

    top
    

    

    Load balancer stickyness
    
    
    
    The balancer supports stickyness. When a request is proxied
    to some back-end, then all following requests from the same user
    should be proxied to the same back-end. Many load balancers implement
    this feature via a table that maps client IP addresses to back-ends.
    This approach is transparent to clients and back-ends, but suffers
    from some problems: unequal load distribution if clients are themselves
    hidden behind proxies, stickyness errors when a client uses a dynamic
    IP address that changes during a session and loss of stickyness, if the
    mapping table overflows.
    
    
    The module mod_proxy_balancer implements stickyness
    on top of two alternative means: cookies and URL encoding. Providing the
    cookie can be either done by the back-end or by the Apache web server
    itself. The URL encoding is usually done on the back-end.
    

    top
    

    

    Examples of a balancer configuration
    
    
    
    Before we dive into the technical details, here's an example of
    how you might use mod_proxy_balancer to provide
    load balancing between two back-end servers:
    
    

    
    <Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80"
    BalancerMember "http://192.168.1.51:80"
</Proxy>
ProxyPass        "/test" "balancer://mycluster"
ProxyPassReverse "/test" "balancer://mycluster"
    


    
    Another example of how to provide load balancing with stickyness
    using mod_headers, even if the back-end server does
    not set a suitable session cookie:
    
    

    
    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED
<Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80" route=1
    BalancerMember "http://192.168.1.51:80" route=2
    ProxySet stickysession=ROUTEID
</Proxy>
ProxyPass        "/test" "balancer://mycluster"
ProxyPassReverse "/test" "balancer://mycluster"
    


    top
    

    

    Exported Environment Variables
    
    
    
    At present there are 6 environment variables exported:
    

    
    
    
    
    BALANCER_SESSION_STICKY
    
    
    
    
    This is assigned the stickysession value used for the current
    request.  It is the name of the cookie or request parameter used for sticky sessions
    
    
    

    
    
    BALANCER_SESSION_ROUTE
    
    
    
    
    This is assigned the route parsed from the current
    request.
    
    
    

    
    
    BALANCER_NAME
    
    
    
    
    This is assigned the name of the balancer used for the current
    request. The value is something like balancer://foo.
    
    
    

    
    
    BALANCER_WORKER_NAME
    
    
    
    
    This is assigned the name of the worker used for the current request.
    The value is something like http://hostA:1234.
    
    
    

    
    
    BALANCER_WORKER_ROUTE
    
    
    
    
    This is assigned the route of the worker that will be
    used for the current request.
    
    
    

    
    
    BALANCER_ROUTE_CHANGED
    
    
    
    
    This is set to 1 if the session route does not match the
    worker route (BALANCER_SESSION_ROUTE != BALANCER_WORKER_ROUTE) or the
    session does not yet have an established route.  This can be used to
    determine when/if the client needs to be sent an updated route
    when sticky sessions are used.

    Enabling Balancer Manager Support
    
    
    
    This module requires the service of
    mod_status.
    Balancer manager enables dynamic update of balancer
    members. You can use balancer manager to change the balance
    factor of a particular member, or put it in the off line
    mode.
    
    

    
    Thus, in order to get the ability of load balancer management,
    mod_status and mod_proxy_balancer
    have to be present in the server.
    

    
    To enable load balancer management for browsers from the example.com
    domain add this code to your httpd.conf
    configuration file
    

    <Location "/balancer-manager">
    SetHandler balancer-manager
    Require host example.com
</Location>
    


    
    You can now access load balancer manager by using a Web browser
    to access the page
    http://your.server.name/balancer-manager. Please note
    that only Balancers defined outside of <Location ...>
    containers can be dynamically controlled by the Manager.

    Details on load balancer stickyness
    
    
    
    When using cookie based stickyness, you need to configure the
    name of the cookie that contains the information about which back-end
    to use. This is done via the stickysession attribute added
    to either ProxyPass or
    ProxySet. The name of
    the cookie is case-sensitive. The balancer extracts the value of the
    cookie and looks for a member worker with route equal
    to that value. The route must also be set in either
    ProxyPass or
    ProxySet. The cookie can either
    be set by the back-end, or as shown in the above
    example by the Apache web server itself.
    
    
    Some back-ends use a slightly different form of stickyness cookie,
    for instance Apache Tomcat. Tomcat adds the name of the Tomcat instance
    to the end of its session id cookie, separated with a dot (.)
    from the session id. Thus if the Apache web server finds a dot in the value
    of the stickyness cookie, it only uses the part behind the dot to search
    for the route. In order to let Tomcat know about its instance name, you
    need to set the attribute jvmRoute inside the Tomcat
    configuration file conf/server.xml to the value of the
    route of the worker that connects to the respective Tomcat.
    The name of the session cookie used by Tomcat (and more generally by Java
    web applications based on servlets) is JSESSIONID
    (upper case) but can be configured to something else.
    
    
    The second way of implementing stickyness is URL encoding.
    The web server searches for a query parameter in the URL of the request.
    The name of the parameter is specified again using stickysession.
    The value of the parameter is used to lookup a member worker with route
    equal to that value. Since it is not easy to extract and manipulate all
    URL links contained in responses, generally the work of adding the parameters
    to each link is done by the back-end generating the content.
    In some cases it might be feasible doing
    this via the web server using mod_substitute or
    mod_sed. This can have negative impact on performance though.
    
    
    The Java standards implement URL encoding slightly different. They use
    a path info appended to the URL using a semicolon (;)
    as the separator and add the session id behind. As in the cookie case,
    Apache Tomcat can include the configured jvmRoute in this path
    info. To let Apache find this sort of path info, you need to set
    scolonpathdelim to On in
    ProxyPass or
    ProxySet.
    
    
    Finally you can support cookies and URL encoding at the same time, by
    configuring the name of the cookie and the name of the URL parameter
    separated by a vertical bar (|) as in the following example:
    
    
    ProxyPass "/test" "balancer://mycluster" stickysession=JSESSIONID|jsessionid scolonpathdelim=On
<Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80" route=node1
    BalancerMember "http://192.168.1.51:80" route=node2
</Proxy>
    

    
    If the cookie and the request parameter both provide routing information
    for the same request, the information from the request parameter is used.

    Troubleshooting load balancer stickyness
    
    
    
    If you experience stickyness errors, e.g. users lose their
    application sessions and need to login again, you first want to
    check whether this is because the back-ends are sometimes unavailable
    or whether your configuration is wrong. To find out about possible
    stability problems with the back-ends, check your Apache error log
    for proxy error messages.
    
    
    To verify your configuration, first check, whether the stickyness
    is based on a cookie or on URL encoding. Next step would be logging
    the appropriate data in the access log by using an enhanced
    LogFormat.
    The following fields are useful:
    
    
    
    
    %{MYCOOKIE}C
    
    
    The value contained in the cookie with name MYCOOKIE.
    The name should be the same given in the stickysession
    attribute.
    
    
    %{Set-Cookie}o
    
    
    This logs any cookie set by the back-end. You can track,
    whether the back-end sets the session cookie you expect, and
    to which value it is set.
    
    
    %{BALANCER_SESSION_STICKY}e
    
    
    The name of the cookie or request parameter used
    to lookup the routing information.
    
    
    %{BALANCER_SESSION_ROUTE}e
    
    
    The route information found in the request.
    
    
    %{BALANCER_WORKER_ROUTE}e
    
    
    The route of the worker chosen.
    
    
    %{BALANCER_ROUTE_CHANGED}e
    
    
    Set to 1 if the route in the request
    is different from the route of the worker, i.e.
    the request couldn't be handled sticky.
    
    
    
    
    Common reasons for loss of session are session timeouts,
    which are usually configurable on the back-end server.
    
    
    The balancer also logs detailed information about handling
    stickyness to the error log, if the log level is set to
    debug or higher. This is an easy way to
    troubleshoot stickyness problems, but the log volume might
    be too high for production servers under high load.

    概要
    

    
    mod_access_compat により提供されるディレクティブは
    サーバの特定の部分への
    アクセスを制御するために <Directory>, <Files>, <Location>
    と .htaccess ファイルで使用されます。クライアントのホスト名、IP
    アドレスや、環境変数などのリクエストの特徴に基づいて
    アクセス制御を行なうことができます。Allow と
    Deny ディレクティブを使って、
    どのようなクライアントにアクセスを
    許可する、しないを指定します。また
    Order ディレクティブを使って、
    デフォルトのアクセス状態と、
    Allow ディレクティブと
    Deny
    ディレクティブとのお互いへの影響の仕方を設定します。
    
    

    
    ホストによるアクセス制限とパスワードによる認証を、
    同時に組み合わせて使うこともできます。
    この場合、その二つの制限の関係を指定するために
    Satisfy
    ディレクティブを使用します。
    

    
    Note
    
      
    mod_access_compatが提供するディレクティブは、
      承認の仕組みの一新に伴い、非推奨になったものです。
      mod_authz_host も見てください。
      デフォルトの承認の取り扱い機能を使用するために
      mod_authz_default
      モジュールもロードされなければなりません。
    
    
    

    
    一般的には、アクセス制限ディレクティブはすべてのアクセスメソッド
    (GET, PUT, POST など)
    に適用されます。そして、ほとんどの場合これが望ましい動作です。
    しかし、<Limit>
    セクションの中にディレクティブを書くことで、
    一部のメソッドにのみ制限をかけることもできます。

    Allow ディレクティブ
    

    

    説明:サーバのある領域にアクセスできるホストを制御する
    

    構文: Allow from all|host|env=[!]env-variable
[host|env=[!]env-variable] ...
    

    コンテキスト:ディレクトリ, .htaccess

    モジュール:mod_access_compat
    

    
    
    Allow ディレクティブは、どのホストが
    サーバのある領域にアクセスできるかに影響を与えます。
    アクセスはホスト名、IP アドレス、IP アドレスの範囲や、
    環境変数などのクライアントのリクエストの
    特徴に基づいてアクセス制御することができます。
     

    
    このディレクティブの最初の引数は常に from です。
    それに続く引数は三つの違った形式があります。Allow from
    all が指定されていれば、すべてのホストにアクセスを許可し、
    アクセス制限は下で説明されているように、
    Deny
    ディレクティブと Order
    ディレクティブの設定で決まります。
    特定のホストやホスト群にのみサーバへのアクセスを許可するためには、
    以下のどれかの形式で host を指定することができます:
    

    
    
      
    ドメイン名 (の一部)
    

      
    
      
    例
    
        Allow from apache.org
    
        Allow from .net example.edu
      
    
      
    この文字列に合うか、これで終わる名前のホストのアクセスが許可されます。
      各部分が完全に合うものだけに適用されますので、上の例は
      foo.apache.org にはマッチしますが、
      fooapache.org にはマッチしません。
      この設定をすると、Apache は
      HostnameLookups
      の設定に関わらず、クライアントの IP アドレスに対して
      DNS の 2 重逆引きを行ないます。
      ホスト名からオリジナルの IP アドレスを順引きします。
      順引きと逆引きが一致し、ホスト名が該当した場合にのみ、
      アクセスが許可されます。
    

      
    完全な IP アドレス
    

      
    
      
    例
    
        Allow from 10.1.2.3
    
        Allow from 192.168.1.104 192.168.1.205
      
    
      
    アクセスを許可する IP アドレスです。
    

      
    IP アドレスの一部
    

      
    
      
    例
    
        Allow from 10.1
    
        Allow from 10 172.20 192.168.2
      
    
      
    サブネットの制限用の、IP
      アドレスの最初の一つから三つまでのバイトです。
    

      
    ネットワーク/ネットマスク の対
    

      
    
      
    例
    
        Allow from 10.1.0.0/255.255.0.0
      
    
      
    ネットワーク a.b.c.d とネットマスク w.x.y.z です。
      より細粒度のサブネット制限用です。
    

      
    ネットワーク/nnn CIDR 指定
    

      
    
      
    例
    
        Allow from 10.1.0.0/16
      
    
      
    ネットマスクが nnn の上位ビットが 1
      となっているものからなること以外は前のものと同じです。
    
    
    

    
    注: 最後の三つの例はまったく同じホストに合います。
    


    
    IPv6 アドレスと IPv6 のサブネットは以下のように指定できます:
    

    
    
       Allow from 2001:db8::a00:20ff:fea7:ccea
    
       Allow from 2001:db8::a00:20ff:fea7:ccea/10
    
    

    
    Allow ディレクティブの引数の三つ目の形式は、
    環境変数
    の存在によりアクセスの制御を行なえるようにするものです。
    Allow from env=env-variable
    が指定されていると、環境変数 env-variable
    が存在した場合にリクエストはアクセスを許可されます。
    Allow from env=!env-variable
    が指定されていると、環境変数 env-variable
    が存在しない場合にアクセス許可されます。
    サーバは mod_setenvif
    のディレクティブにより、クライアントのリクエスト
    の特徴に基づいて柔軟に環境変数を設定する機能を提供します。
    ですから、このディレクティブはクライアントの
    User-Agent (ブラウザの種類)、Referer
    や他の HTTP リクエストのヘッダフィールドなどに基づいて
    アクセス許可をするために使うことができます。
    
    

    
    Example:
    
      SetEnvIf User-Agent ^KnockKnock/2\.0 let_me_in
    
      <Directory /docroot>
    
      
        Order Deny,Allow
    
        Deny from all
    
        Allow from env=let_me_in
    
          
      </Directory>
    
    

    
    この場合、user-agent の文字列が KnockKnock/2.0
    で始まるブラウザのみがアクセスが許可され、
    他のものはアクセスが拒否されます。
    



    

    top
    

    Deny ディレクティブ
    

    

    説明:サーバがアクセスを拒否するホストを制御する
    

    構文: Deny from all|host|env=[!]env-variable
[host|env=[!]env-variable] ...

    上書き:Limit
    

    ステータス:Extension
    

    モジュール:mod_access_compat
    

    
    
    このディレクティブはホスト名、IP
    アドレス、環境変数に基づいてサーバへのアクセスを制限します。
    Deny ディレクティブの引数は Allow
    ディレクティブとまったく同じです。
    


    

    top
    

    Order ディレクティブ
    

    

    説明:デフォルトのアクセス可能な状態と、Allow と
Deny が評価される順番を制御する
    

    構文: Order ordering
    

    デフォルト:Order Deny,Allow
    

    コンテキスト:ディレクトリ, .htaccess
    

    上書き:Limit
    

    ステータス:Extension
    

    モジュール:mod_access_compat
    

    

    
    Order ディレクティブは Allow ディレクティブとDeny と共に"3段階アクセス制御システム"
    を制御します。第1段階目では Order ディレクティブで1番目に
    指定したディレクティブ(Allow 
    または Deny)を全て処理します。
    第2段階目で、残りのディレクティブ(Deny または Allow)
    を全て処理します。第3段階目で、第1段階目と第2段階目で
    マッチしなかったリクエストを処理します。
    

    
    全ての Allow と Deny が処理され、結局のところ最後にマッチ
    した条件が有効となることに注意してください。これは最初にマッチした条件だけが有効
    となる、典型的なファイアウォールの動作とは異なっています。
    また、設定ファイルに書く順番には意味はありません。Allow 行は全部一つのグループとして扱われ、
    Deny 行はもう一つのグループとみなされます。
    またデフォルト状態は単独で一つのグループとみなされます。
    

    
    Order 設定は以下のどれかです。
    

    
    
      
    Allow,Deny
    

      
    まず Allow 
      ディレクティブが適用されます。どれにもマッチしなかった場合、この時点で
      リクエストは拒否されます。次に、全ての 
      Deny ディレクティブが適用されます。どれか一つでもマッチした場合は、
      リクエストは拒否されます。
      最後に、 Allow にも Deny にもマッチしなかったリクエストは
      デフォルト設定が適用されるので拒否されます。
    

      
    Deny,Allow
    

      
    まず Deny 
      ディレクティブが適用されます。どれか一つでもマッチした場合は、
      Allow のどれにも
      マッチしなければ、アクセスは拒否されます。
      どの Allow にも Deny にもマッチしないリクエストは
      許可されます。
    

      
    Mutual-failure
    

      
    これは Order Allow,Deny と全く同じ効果を持ち、 
      そのため非推奨となっています。
      
    
    
    

    
    キーワードの間に置けるのはコンマだけです。

        どちらにもマッチしない
        2番目のディレクティブがデフォルト: 拒否
        2番目のディレクティブがデフォルト: 許可
      
    
        Allow と Deny 両方にマッチ
        最後にマッチしたほう: 拒否
        最後にマッチしたほう: 許可
      
    
    
    

    
    以下の例では、apache.org
    ドメインのすべてのホストはアクセスを許可されます。
    他のすべてのホストはアクセスを拒否されます。
    

    
    
      Order Deny,Allow
    
      Deny from all
    
      Allow from apache.org
    
    

    
    次の例では、foo.apache.org サブドメインにあるホスト以外の、
    apache.org ドメインのすべてのホストがアクセスを許可されます。
    apache.org
    ドメインでないホストは、デフォルトの状態が Deny のため、
    サーバへのアクセスを拒否されます。
    

    
    
      Order Allow,Deny
    
      Allow from apache.org
    
      Deny from foo.apache.org
    
    

    
    一方、上の例の Order が Deny,Allow
    に変わっていれば、すべのホストにアクセスが許可されます。
    これは、設定ファイル中の実際の順番に関わらず、
    Allow from apache.org が最後に評価されて、
    Deny from foo.apache.org を上書きするからです。
    apache.org
    ドメインにないホストも、デフォルトの状態が Allow
    なので、アクセスを許可されます。
    
    

    
    Order
    ディレクティブはデフォルトのアクセスの状態に影響を与えるので、
    Allow ディレクティブと
    Deny
    ディレクティブが無くても、サーバのアクセスに影響を与えることができます。
    たとえば、
    

    
    
      <Directory /www>
    
      
        Order Allow,Deny
    
          
      </Directory>
    
    

    
    はデフォルトのアクセス状態が 
    Deny になるため、
    /www ディレクトリへのすべてのアクセスを拒否します。
    
    

    
    Order
    ディレクティブはサーバの設定処理の各段階でだけ
    アクセスディレクティブの処理の順番を変更します。これは、たとえば、
    Order ディレクティブの設定に関わらず、
    <Location> セクションの
    Allow ディレクティブや
    Deny ディレクティブは、
    Directory セクションや
    .htaccess ファイルの Allow
    ディレクティブや Deny
    ディレクティブよりも常に後に評価されるということを意味します。
    設定セクションのマージの詳細については、
    Directory,Location, Files
    セクションの動作方法 を参照してください。

    Allow と
    Require の両方が使われているときの
    アクセスポリシーを設定します。パラメータは All か Any
    です。このディレクティブはある場所へのアクセスがユーザ名/パスワード
    とクライアントのホストのアドレスで制限されているときにのみ
    役立ちます。デフォルトの動作 (All) はクライアントがアドレスによる
    アクセス制限を満たし、かつ正しいユーザ名とパスワードを入力することを
    要求します。Any では、クライアントはホストの制限を満たすか、
    正しいユーザ名とパスワードの入力をするかをすればアクセスを許可されます。
    これは、ある場所をパスワードで保護するけれど、特定のアドレスからの
    クライアントにはパスワードの入力を要求せずにアクセスを許可する、
    というようなときに使用できます。
    

    
    例えば、同じネットワーク上にいる人にはウェブサイトのある部分について
    無制限のアクセスを許したいけれど、外のネットワークの人には
    パスワードを提供させるようにするためには、次のような設定をすることが
    できます:
    

    
    
    Require valid-user
    
    Allow from 192.168.1
    
    Satisfy Any
    
    
   
    
    バージョン 2.0.51 からは
    <Limit> セクションと
    <LimitExcept> セクションを使用することで
    Satisfy ディレクティブが
    適用されるメソッドを制限することが
    できるようになりました。

    Apache HTTP Server Version 2.4
    

    

    <-
    


    

    Apache Module mod_reflector
    

    

    Available Languages:  en  |

    Description:Reflect a request body as a response via the output filter stack.
    

    Status:Base
    

    Module Identifier:reflector_module
    

    Source File:mod_reflector.c
    

    Compatibility:Version 2.3 and later
    

    Summary
    

    
    This module allows request bodies to be reflected back to the
    client, in the process passing the request through the output filter
    stack. A suitably configured chain of filters can be used to transform
    the request into a response. This module can be used to turn an output
    filter into an HTTP service.

    Examples
    
    
    
    
    Compression service
    
    
    Pass the request body through the DEFLATE filter to compress the
    body. This request requires a Content-Encoding request header containing
    "gzip" for the filter to return compressed data.
    
    <Location "/compress">
    SetHandler reflector
    SetOutputFilter DEFLATE
</Location>
    

    
    

    
    Image downsampling service
    
    
    Pass the request body through an image downsampling filter, and reflect
    the results to the caller.
    
    <Location "/downsample">
    SetHandler reflector
    SetOutputFilter DOWNSAMPLE
</Location>

    Description:Reflect an input header to the output headers
    

    Syntax:ReflectorHeader inputheader [outputheader]
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Base
    

    Module:mod_reflector
    

    
    
    This directive controls the reflection of request headers to the response.
    The first argument is the name of the request header to copy. If the optional
    second argument is specified, it will be used as the name of the response
    header, otherwise the original request header name will be used.

    Description:Provides for "trailing slash" redirects and
    serving directory index files
    

    Status:Base
    

    Module Identifier:dir_module
    

    Source File:mod_dir.c
    

    Summary
    

    
    The index of a directory can come from one of two sources:
    

    
      
      
    • A file written by the user, typically called
      index.html. The DirectoryIndex directive sets the
      name of this file. This is controlled by
      mod_dir.
      • 

      
    • Otherwise, a listing generated by the server. This is
      provided by mod_autoindex.
      • 
    
    
    
    The two functions are separated so that you can completely
    remove (or replace) automatic index generation should you want
    to.
    

    
    A "trailing slash" redirect is issued when the server
    receives a request for a URL
    http://servername/foo/dirname where
    dirname is a directory. Directories require a
    trailing slash, so mod_dir issues a redirect to
    http://servername/foo/dirname/.

    DirectoryCheckHandler Directive
    

    

    Description:Toggle how this module responds when another handler is configured
    

    Syntax:DirectoryCheckHandler On|Off
    

    Default:DirectoryCheckHandler Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_dir
    

    Compatibility:Available in 2.4.8 and later.  Releases prior to 2.4 implicitly
act as if "DirectoryCheckHandler ON" was specified.
    

    
    
    The DirectoryCheckHandler directive determines 
    whether mod_dir should check for directory indexes or
    add trailing slashes when some other handler has been configured for
    the current URL.  Handlers can be set by directives such as 
    SetHandler or by other modules,
    such as mod_rewrite during per-directory substitutions.
    
    

    
     In releases prior to 2.4, this module did not take any action if any
    other handler was configured for a URL. This allows directory indexes to 
    be served even when a SetHandler directive is 
    specified for an entire directory, but it can also result in some conflicts
    with modules such as mod_rewrite.

    DirectoryIndex Directive
    

    

    Description:List of resources to look for when the client requests
a directory
    

    Syntax:DirectoryIndex
    disabled | local-url [local-url] ...
    

    Default:DirectoryIndex index.html
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_dir
    

    
    
    The DirectoryIndex directive sets the
    list of resources to look for, when the client requests an index
    of the directory by specifying a / at the end of the directory
    name.  Local-url is the (%-encoded) URL of a document on
    the server relative to the requested directory; it is usually the
    name of a file in the directory. Several URLs may be given, in
    which case the server will return the first one that it finds.  If
    none of the resources exist and the Indexes option is
    set, the server will generate its own listing of the
    directory.
    

    
    Example
    DirectoryIndex index.html
    

    

    
    then a request for http://example.com/docs/ would
    return http://example.com/docs/index.html if it
    exists, or would list the directory if it did not.
    

    
    Note that the documents do not need to be relative to the
    directory;
    

    
    DirectoryIndex index.html index.txt  /cgi-bin/index.pl
    


    
    would cause the CGI script /cgi-bin/index.pl to be
    executed if neither index.html or index.txt
    existed in a directory.
    

    
    A single argument of "disabled" prevents mod_dir from
    searching for an index.  An argument of "disabled" will be interpreted
    literally if it has any arguments before or after it, even if they are "disabled"
    as well.
    

    
    Note: Multiple DirectoryIndex
    directives within the same context will add
    to the list of resources to look for rather than replace:
    
    
    
    # Example A: Set index.html as an index page, then add index.php to that list as well.
<Directory "/foo">
    DirectoryIndex index.html
    DirectoryIndex index.php
</Directory>

# Example B: This is identical to example A, except it's done with a single directive.
<Directory "/foo">
    DirectoryIndex index.html index.php
</Directory>

# Example C: To replace the list, you must explicitly reset it first:
# In this example, only index.php will remain as an index resource.
<Directory "/foo">
    DirectoryIndex index.html
    DirectoryIndex disabled
    DirectoryIndex index.php
</Directory>

    DirectoryIndexRedirect Directive
    

    

    Description:Configures an external redirect for directory indexes.

    

    Syntax:DirectoryIndexRedirect on | off | permanent | temp | seeother |
3xx-code

    

    Default:DirectoryIndexRedirect off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_dir
    

    Compatibility:Available in version 2.3.14 and later
    

    
    
    By default, the DirectoryIndex is selected
    and returned transparently to the client.  DirectoryIndexRedirect causes an external redirect
    to instead be issued.
    

    
    The argument can be:
    
    
      
     
    • on: issues a 302 redirection to the index resource.
      • 
     
    • off: does not issue a redirection. This is the legacy behaviour of mod_dir.
      • 
     
    • permanent: issues a 301 (permanent) redirection to the index resource.
      • 
     
    • temp: this has the same effect as on
      • 
     
    • seeother: issues a 303 redirection (also known as "See Other") to the index resource.
      • 
     
    • 3xx-code: issues a redirection marked by the chosen 3xx code.
      • 
    
    


    
    Example
    DirectoryIndexRedirect on
    

    

    
    A request for http://example.com/docs/ would
    return a temporary redirect to http://example.com/docs/index.html
    if it exists.

    DirectorySlash Directive
    

    

    Description:Toggle trailing slash redirects on or off
    

    Syntax:DirectorySlash On|Off
    

    Default:DirectorySlash On
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_dir
    

    
    
    The DirectorySlash directive determines whether
    mod_dir should fixup URLs pointing to a directory or
    not.
    

    
    Typically if a user requests a resource without a trailing slash, which
    points to a directory, mod_dir redirects him to the same
    resource, but with trailing slash for some good reasons:
    

    
      
    
    • The user is finally requesting the canonical URL of the resource
      • 
    
    • mod_autoindex works correctly. Since it doesn't emit
    the path in the link, it would point to the wrong path.
      • 
    
    • DirectoryIndex will be evaluated
    only for directories requested with trailing slash.
      • 
    
    • Relative URL references inside html pages will work correctly.
      • 
    
    

    
    If you don't want this effect and the reasons above don't
    apply to you, you can turn off the redirect as shown below. However,
    be aware that there are possible security implications to doing
    this.
    

    
    # see security warning below!
<Location "/some/path">
    DirectorySlash Off
    SetHandler some-handler
</Location>
    


    
    Security Warning
    
    
    Turning off the trailing slash redirect may result in an information
    disclosure. Consider a situation where mod_autoindex is
    active (Options +Indexes) and DirectoryIndex is set to a valid resource (say,
    index.html) and there's no other special handler defined for
    that URL. In this case a request with a trailing slash would show the
    index.html file. But a request without trailing slash
    would list the directory contents.
    
    
    
	
    Also note that some browsers may erroneously change POST requests into GET
	(thus discarding POST data) when a redirect is issued.

    FallbackResource Directive
    

    

    Description:Define a default URL for requests that don't map to a file
    

    Syntax:FallbackResource disabled | local-url
    

    Default:disabled - httpd will return 404 (Not Found)
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_dir
    

    Compatibility:The disabled argument is available in version 2.4.4 and
later
    

    
    
    Use this to set a handler for any URL that doesn't map to anything
    in your filesystem, and would otherwise return HTTP 404 (Not Found).
    For example
    
    
    FallbackResource /not-404.php
    

    
    will cause requests for non-existent files to be handled by
    not-404.php, while requests for files that exist
    are unaffected.
    
    
    It is frequently desirable to have a single file or resource
    handle all requests to a particular directory, except those requests
    that correspond to an existing file or script. This is often
    referred to as a 'front controller.'
    
    
    In earlier versions of httpd, this effect typically required
    mod_rewrite, and the use of the -f and
    -d tests for file and directory existence. This now
    requires only one line of configuration.
    
    
    FallbackResource /index.php
    

    
    Existing files, such as images, css files, and so on, will be
    served normally.
    
    
    Use the disabled argument to disable that feature
    if inheritance from a parent directory is not desired.
    
    
    In a sub-URI, such as http://example.com/blog/ this
    sub-URI has to be supplied as local-url:
    
    
    <Directory "/web/example.com/htdocs/blog">
    FallbackResource /blog/index.php
</Directory>
<Directory "/web/example.com/htdocs/blog/images">
    FallbackResource disabled
</Directory>
    

    
    A fallback handler (in the above case, /blog/index.php)
    can access the original requested URL via the server variable
    REQUEST_URI. For example, to access this variable in PHP,
    use $_SERVER['REQUEST_URI'].

mod_authz_host - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4
    

    

    <-
    


    

    Apache Module mod_authz_host
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Group authorizations based on host (name or IP
address)
    

    Status:Base
    

    Module Identifier:authz_host_module
    

    Source File:mod_authz_host.c
    

    Compatibility:The forward-dns provider was added in 2.4.19
    

    Summary
    

    
    The authorization providers implemented by mod_authz_host are
    registered using the Require
    directive. The directive can be referenced within a
    <Directory>,
    <Files>,
    or <Location> section
    as well as .htaccess
     files to control access to particular parts of the server.
    Access can be controlled based on the client hostname or IP address.
    

    
    In general, access restriction directives apply to all
    access methods (GET, PUT,
    POST, etc). This is the desired behavior in most
    cases. However, it is possible to restrict some methods, while
    leaving other methods unrestricted, by enclosing the directives
    in a <Limit> section.
    

    


    top
    

    

    The Require Directives
    

    
    Apache's Require
    directive is used during the authorization phase to ensure that a user is allowed or
    denied access to a resource.  mod_authz_host extends the
    authorization types with ip, host,
    forward-dns and local.
    Other authorization types may also be
    used but may require that additional authorization modules be loaded.
    

    
    These authorization providers affect which hosts can
    access an area of the server. Access can be controlled by
    hostname, IP Address, or IP Address range.
    

    
    Since v2.4.8, expressions are supported
    within the host require directives.
    


    Require ip
    

    
    The ip provider allows access to the server
    to be controlled based on the IP address of the remote client.
    When Require ip ip-address is specified,
    then the request is allowed access if the IP address matches.
    

    
    A full IP address:
    

    
    Require ip 10.1.2.3
Require ip 192.168.1.104 192.168.1.205
    


    
    An IP address of a host allowed access
    

    
    A partial IP address:
    

    
    Require ip 10.1
Require ip 10 172.20 192.168.2
    

    
    The first 1 to 3 bytes of an IP address, for subnet
    restriction.
    

    
    A network/netmask pair:
    

    
    Require ip 10.1.0.0/255.255.0.0
    

    
    A network a.b.c.d, and a netmask w.x.y.z. For more
    fine-grained subnet restriction.
    

    
    A network/nnn CIDR specification:
    

    
    Require ip 10.1.0.0/16
    

    
    Similar to the previous case, except the netmask consists of
    nnn high-order 1 bits.
    

    
    Note that the last three examples above match exactly the
    same set of hosts.
    

    
    IPv6 addresses and IPv6 subnets can be specified as shown
    below:
    

    
    Require ip 2001:db8::a00:20ff:fea7:ccea
Require ip 2001:db8:1:1::a
Require ip 2001:db8:2:1::/64
Require ip 2001:db8:3::/48
    


    
    Note: As the IP addresses are parsed on startup, expressions are
    not evaluated at request time.
    




    Require host
    

    
    The host provider allows access to the server
    to be controlled based on the host name of the remote client.
    When Require host host-name is specified,
    then the request is allowed access if the host name matches.
    

    
    A (partial) domain-name
    

    
    Require host example.org
Require host .net example.edu
    


    
    Hosts whose names match, or end in, this string are allowed
    access. Only complete components are matched, so the above
    example will match foo.example.org but it will not
    match fooexample.org. This configuration will cause
    Apache to perform a double reverse DNS lookup on the client IP
    address, regardless of the setting of the HostnameLookups directive.  It will do
    a reverse DNS lookup on the IP address to find the associated
    hostname, and then do a forward lookup on the hostname to assure
    that it matches the original IP address.  Only if the forward
    and reverse DNS are consistent and the hostname matches will
    access be allowed.
    




    Require forward-dns
    

    
    The forward-dns provider allows access to the server
    to be controlled based on simple host names.  When
    Require forward-dns host-name is specified,
    all IP addresses corresponding to host-name
    are allowed access.
    

    
    In contrast to the host provider, this provider does not
    rely on reverse DNS lookups: it simply queries the DNS for the host name
    and allows a client if its IP matches.  As a consequence, it will only
    work with host names, not domain names.  However, as the reverse DNS is
    not used, it will work with clients which use a dynamic DNS service.
    

    
    Require forward-dns dynamic.example.org
    


    
    A client the IP of which is resolved from the name
    dynamic.example.org will be granted access.
    

    
    The forward-dns provider was added in 2.4.19.
    



    Require local
    

    
    The local provider allows access to the server if any
    of the following conditions is true:
    

    
      
        
    • the client address matches 127.0.0.0/8
      • 
        
    • the client address is ::1
      • 
        
    • both the client and the server address of the connection are
        the same
      • 
    
    

    
    This allows a convenient way to match connections that originate from
    the local host:
    

    
    Require local
    





    Security Note
    

    
    If you are proxying content to your server, you need to be aware
    that the client address will be the address of your proxy server,
    not the address of the client, and so using the Require
    directive in this context may not do what you mean. See
    mod_remoteip for one possible solution to this
    problem.

    Summary
    

    
    Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP
    headers that can be output in addition to the normal range of
    headers for each file accessed. They appear rather like the
    Apache .asis files, and are able to provide a crude way of
    influencing the Expires: header, as well as providing other
    curiosities. There are many ways to manage meta information,
    this one was chosen because there is already a large number of
    CERN users who can exploit this module.
    

    
    More information on the CERN metafile semantics is available.

    Specifies the name of the directory in which Apache can find
    meta information files. The directory is usually a 'hidden'
    subdirectory of the directory that contains the file being
    accessed. Set to "." to look in the same directory
    as the file:
    

    
    MetaDir .
    


    
    Or, to set it to a subdirectory of the directory containing the

    Specifies the file name suffix for the file containing the
    meta information. For example, the default values for the two
    directives will cause a request to
    DOCUMENT_ROOT/somedir/index.html to look in
    DOCUMENT_ROOT/somedir/.web/index.html.meta and
    will use its contents to generate additional MIME header
    information.
    

    
    Example:
    MetaSuffix .meta

    Summary
    

    
    This module provides core authorization capabilities so that
    authenticated users can be allowed or denied access to portions
    of the web site. mod_authz_core provides the
    functionality to register various authorization providers. It is
    usually used in conjunction with an authentication
    provider module such as mod_authn_file and an
    authorization module such as mod_authz_user. It
    also allows for advanced logic to be applied to the
    authorization processing.

    Authorization Containers
    

    
    The authorization container directives
    <RequireAll>,
    <RequireAny>
    and
    <RequireNone>
    may be combined with each other and with the
    Require
    directive to express complex authorization logic.
    

    
    The example below expresses the following authorization logic.
    In order to access the resource, the user must either be the
    superadmin user, or belong to both the
    admins group and the Administrators LDAP
    group and either belong to the sales group or
    have the LDAP dept attribute sales.
    Furthermore, in order to access the resource, the user must
    not belong to either the temps group or the
    LDAP group Temporary Employees.
    

    
    <Directory "/www/mydocs">
    <RequireAll>
        <RequireAny>
            Require user superadmin
            <RequireAll>
                Require group admins
                Require ldap-group "cn=Administrators,o=Airius"
                <RequireAny>
                    Require group sales
                    Require ldap-attribute dept="sales"
                </RequireAny>
            </RequireAll>
        </RequireAny>
        <RequireNone>
            Require group temps
            Require ldap-group "cn=Temporary Employees,o=Airius"
        </RequireNone>
    </RequireAll>
</Directory>
    


    top
    

    

    The Require Directives
    

  
    mod_authz_core provides some generic authorization
  providers which can be used with the
  Require directive.
    

  
    Require env
    

    
    The env provider allows access to the server
    to be controlled based on the existence of an environment variable. When Require
    env env-variable is specified, then the request is
    allowed access if the environment variable env-variable
    exists. The server provides the ability to set environment
    variables in a flexible way based on characteristics of the client
    request using the directives provided by
    mod_setenvif. Therefore, this directive can be
    used to allow access based on such factors as the clients
    User-Agent (browser type), Referer, or
    other HTTP request header fields.
    

    
    SetEnvIf User-Agent "^KnockKnock/2\.0" let_me_in
<Directory "/docroot">
    Require env let_me_in
</Directory>
    


    
    In this case, browsers with a user-agent string beginning
    with KnockKnock/2.0 will be allowed access, and all
    others will be denied.
    

    
    When the server looks up a path via an internal
    subrequest such as looking
    for a DirectoryIndex
    or generating a directory listing with mod_autoindex,
    per-request environment variables are not inherited in the
    subrequest. Additionally,
    SetEnvIf directives
    are not separately evaluated in the subrequest due to the API phases
    mod_setenvif takes action in.
    

  

  
    Require all
    

    
    The all provider mimics the functionality that
    was previously provided by the 'Allow from all' and 'Deny from all'
    directives.  This provider can take one of two arguments which are
    'granted' or 'denied'.  The following examples will grant or deny
    access to all requests.
    

    
    Require all granted
    


    
    Require all denied
    


  

  
    Require method
    

    
    The method provider allows using the HTTP method in
    authorization decisions. The GET and HEAD methods are treated as
    equivalent. The TRACE method is not available to this provider,
    use TraceEnable instead.
    

    
    The following example will only allow GET, HEAD, POST, and OPTIONS
    requests:
    

    
    Require method GET POST OPTIONS
    


    
    The following example will allow GET, HEAD, POST, and OPTIONS
    requests without authentication, and require a valid user for all other
    methods:
    

    
    <RequireAny>
     Require method GET POST OPTIONS
     Require valid-user
</RequireAny>
    


  

  
    Require expr
    

  
    The expr provider allows basing authorization
  decisions on arbitrary expressions.
    

    
    Require expr "%{TIME_HOUR} -ge 9 && %{TIME_HOUR} -le 17"
    


    
    <RequireAll>
    Require expr "!(%{QUERY_STRING} =~ /secret/)"
    Require expr "%{REQUEST_URI} in { '/example.cgi', '/other.cgi' }"
</RequireAll>
    


    
    Require expr "!(%{QUERY_STRING} =~ /secret/) && %{REQUEST_URI} in { '/example.cgi', '/other.cgi' }"
    


  
    The syntax is described in the ap_expr
  documentation. Before httpd 2.4.16, the surrounding double-quotes MUST be
  omitted.
    

  
    Normally, the expression is evaluated before authentication. However, if
  the expression returns false and references the variable
  %{REMOTE_USER}, authentication will be performed and
  the expression will be re-evaluated.

    Creating Authorization Provider Aliases
    

    
    Extended authorization providers can be created within the configuration
    file and assigned an alias name.  The alias providers can then be referenced
    through the Require directive
    in the same way as a base authorization provider.  Besides the ability to
    create and alias an extended provider, it also allows the same extended
    authorization provider to be referenced by multiple locations.
    
    

    
    Example
    
        
    The example below creates two different ldap authorization provider
        aliases based on the ldap-group authorization provider.  This example
        allows a single authorization location to check group membership within
        multiple ldap hosts:
        
    

        
    <AuthzProviderAlias ldap-group ldap-group-alias1 "cn=my-group,o=ctx">
    AuthLDAPBindDN "cn=youruser,o=ctx"
    AuthLDAPBindPassword yourpassword
    AuthLDAPUrl "ldap://ldap.host/o=ctx"
</AuthzProviderAlias>

<AuthzProviderAlias ldap-group ldap-group-alias2 "cn=my-other-group,o=dev">
    AuthLDAPBindDN "cn=yourotheruser,o=dev"
    AuthLDAPBindPassword yourotherpassword
    AuthLDAPUrl "ldap://other.ldap.host/o=dev?cn"
</AuthzProviderAlias>

Alias "/secure" "/webpages/secure"
<Directory "/webpages/secure">
    Require all granted

    AuthBasicProvider file

    AuthType Basic
    AuthName LDAP_Protected_Place

    #implied OR operation
    Require ldap-group-alias1
    Require ldap-group-alias2
</Directory>

    AuthMerging Directive
    

    

    Description:Controls the manner in which each configuration section's
authorization logic is combined with that of preceding configuration
sections.
    

    Syntax:AuthMerging Off | And | Or
    

    Default:AuthMerging Off
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authz_core
    

    
    
    When authorization is enabled, it is normally inherited by each
    subsequent configuration section,
    unless a different set of authorization directives is specified.
    This is the default action, which corresponds to an explicit setting
    of AuthMerging Off.
    

    
    However, there may be circumstances in which it is desirable
    for a configuration section's authorization to be combined with
    that of its predecessor while configuration sections are being
    merged.  Two options are available for this case, And
    and Or.
    

    
    When a configuration section contains AuthMerging And
    or AuthMerging Or,
    its authorization logic is combined with that of the nearest
    predecessor (according to the overall order of configuration sections)
    which also contains authorization logic as if the two sections
    were jointly contained within a
    <RequireAll> or
    <RequireAny>
    directive, respectively.
    

    
    The setting of AuthMerging is not
    inherited outside of the configuration section in which it appears.
    In the following example, only users belonging to group alpha
    may access /www/docs.  Users belonging to either
    groups alpha or beta may access
    /www/docs/ab.  However, the default Off
    setting of AuthMerging applies to the
    <Directory>
    configuration section for /www/docs/ab/gamma, so
    that section's authorization directives override those of the
    preceding sections.  Thus only users belong to the group
    gamma may access /www/docs/ab/gamma.
    

    
    <Directory "/www/docs">
    AuthType Basic
    AuthName Documents
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    Require group alpha
</Directory>

<Directory "/www/docs/ab">
    AuthMerging Or
    Require group beta
</Directory>

<Directory "/www/docs/ab/gamma">
    Require group gamma
</Directory>

    <AuthzProviderAlias> Directive
    

    

    Description:Enclose a group of directives that represent an
extension of a base authorization provider and referenced by the specified

    If several parameters are needed in Require-Parameters,
    they must be enclosed in quotation marks.  Otherwise, only the first one
    is taken into account.
    
    
    
    # In this example, for both addresses to be taken into account, they MUST be enclosed
# between quotation marks

    AuthzSendForbiddenOnFailure Directive
    

    

    Description:Send '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if
authentication succeeds but authorization fails

    

    Syntax:AuthzSendForbiddenOnFailure On|Off
    

    Default:AuthzSendForbiddenOnFailure Off
    

    Context:directory, .htaccess
    

    Status:Base
    

    Module:mod_authz_core
    

    Compatibility:Available in Apache HTTPD 2.3.11 and later
    

    
    
    If authentication succeeds but authorization fails, Apache HTTPD will
    respond with an HTTP response code of '401 UNAUTHORIZED' by default. This
    usually causes browsers to display the password dialogue to the user
    again, which is not wanted in all situations.
    AuthzSendForbiddenOnFailure allows to change the
    response code to '403 FORBIDDEN'.
    

    
    Security Warning
    
    
    Modifying the response in case of missing authorization weakens the
    security of the password, because it reveals to a possible attacker, that
    his guessed password was right.

    Require Directive

    Context:directory, .htaccess
    

    Override:AuthConfig

    Module:mod_authz_core
    

    
    
    This directive tests whether an authenticated user is authorized
    according to a particular authorization provider and the specified
    restrictions. mod_authz_core provides the following
    generic authorization providers:
    

    
    
      
    Require all granted
    
      
    Access is allowed unconditionally.
    

      
    Require all denied
    
      
    Access is denied unconditionally.
    

      
    Require env env-var [env-var]
      ...
    
      
    Access is allowed only if one of the given environment variables is
          set.
    

      
    Require method http-method [http-method]
      ...
    
      
    Access is allowed only for the given HTTP methods.
    

      
    Require expr expression 
    
      
    Access is allowed if expression evaluates to true.
    
    
    

    
    Some of the allowed syntaxes provided by mod_authz_user,
       mod_authz_host,
       and mod_authz_groupfile are:
    

    
    
      
    Require user userid [userid]
      ...
    
      
    Only the named users can access the resource.
    

      
    Require group group-name [group-name]
      ...
    
      
    Only users in the named groups can access the resource.
    

      
    Require valid-user
    
      
    All valid users can access the resource.
    

      
    Require ip 10 172.20 192.168.2
    
      
    Clients in the specified IP address ranges can access the
      resource.
    

      
    Require forward-dns dynamic.example.org
    
      
    A client the IP of which is resolved from the name dynamic.example.org will be granted access.
      
    

    
    

    
    Other authorization modules that implement require options
    include mod_authnz_ldap,
    mod_authz_dbm, mod_authz_dbd,
    mod_authz_owner and mod_ssl.
    

    
    In most cases, for a complete authentication and authorization
    configuration, Require must be accompanied by
    AuthName, AuthType and
    AuthBasicProvider or
    AuthDigestProvider
    directives, and directives such as
    AuthUserFile
    and AuthGroupFile (to
    define users and groups) in order to work correctly. Example:
    

    
    AuthType Basic
AuthName "Restricted Resource"
AuthBasicProvider file
AuthUserFile "/web/users"
AuthGroupFile "/web/groups"
Require group admin
    


    
    Access controls which are applied in this way are effective for
    all methods. This is what is normally
    desired. If you wish to apply access controls only to
    specific methods, while leaving other methods unprotected, then
    place the Require statement into a
    <Limit>
    section.
    

    
    The result of the Require directive
    may be negated through the use of the
    not option.  As with the other negated authorization
    directive <RequireNone>,
    when the Require directive is negated it can
    only fail or return a neutral result, and therefore may never
    independently authorize a request.
    

    
    In the following example, all users in the alpha
    and beta groups are authorized, except for those who
    are also in the reject group.
    

    
    <Directory "/www/docs">
    <RequireAll>
        Require group alpha beta
        Require not group reject
    </RequireAll>
</Directory>
    


    
    When multiple Require directives are
    used in a single
    configuration section
    and are not contained in another authorization directive like
    <RequireAll>,
    they are implicitly contained within a
    <RequireAny>
    directive.  Thus the first one to authorize a user authorizes the
    entire request, and subsequent Require directives
    are ignored.
    

    
    Security Warning
    
    
    Exercise caution when setting authorization directives in
    Location sections
    that overlap with content served out of the filesystem.
    By default, these configuration sections overwrite authorization configuration
    in Directory,
    and Files sections.
    
    
    The AuthMerging directive
    can be used to control how authorization configuration sections are
    merged.

    <RequireAll> Directive
    

    

    Description:Enclose a group of authorization directives of which none
must fail and at least one must succeed for the enclosing directive to
succeed.

    <RequireAll> and
    </RequireAll> are used to enclose a group of
    authorization directives of which none must fail and at least one
    must succeed in order for
    the <RequireAll> directive to
    succeed.
    

    
    If none of the directives contained within the
    <RequireAll> directive fails,
    and at least one succeeds, then the
    <RequireAll> directive
    succeeds.  If none succeed and none fail, then it returns a
    neutral result.  In all other cases, it fails.

    <RequireAny> Directive
    

    

    Description:Enclose a group of authorization directives of which one
must succeed for the enclosing directive to succeed.
    

    Syntax:<RequireAny> ... </RequireAny>
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authz_core
    

    
    
    <RequireAny> and
    </RequireAny> are used to enclose a group of
    authorization directives of which one must succeed in order for
    the <RequireAny> directive to
    succeed.
    

    
    If one or more of the directives contained within the
    <RequireAny> directive succeed,
    then the <RequireAny> directive
    succeeds.  If none succeed and none fail, then it returns a
    neutral result.  In all other cases, it fails.
    

    
    Because negated authorization directives are unable to
    return a successful result, they can not significantly influence
    the result of a <RequireAny>
    directive.  (At most they could cause the directive to fail in
    the case where they failed and all other directives returned a
    neutral value.)  Therefore negated authorization directives
    are not permitted within a <RequireAny>
    directive.

    <RequireNone> Directive
    

    

    Description:Enclose a group of authorization directives of which none
must succeed for the enclosing directive to not fail.
    

    Syntax:<RequireNone> ... </RequireNone>
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authz_core
    

    
    
    <RequireNone> and
    </RequireNone> are used to enclose a group of
    authorization directives of which none must succeed
    in order for the
    <RequireNone> directive to
    not fail.
    

    
    If one or more of the directives contained within the
    <RequireNone> directive succeed,
    then the <RequireNone> directive
    fails.  In all other cases, it returns a neutral result.  Thus as with
    the other negated authorization directive Require not,
    it can never independently
    authorize a request because it can never return a successful result.
    It can be used, however, to restrict the set of users who are
    authorized to access a resource.
    

    
    Because negated authorization directives are unable to
    return a successful result, they can not significantly influence
    the result of a <RequireNone>
    directive.  Therefore negated authorization directives
    are not permitted within a
    <RequireNone> directive.

mod_proxy - Apache HTTP サーバ バージョン 2.4








    

    モジュール | ディレクティブ | FAQ | 用語 | サイトマップ
    

    Apache HTTP サーバ バージョン 2.4
    

    

    <-
    


    

    Apache モジュール mod_proxy
    

    

    翻訳済み言語:  en  |
 fr  |
 ja 
    

    

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:HTTP/1.1 プロキシ/ゲートウェイサーバ
    

    ステータス:Extension
    

    モジュール識別子:proxy_module
    

    ソースファイル:mod_proxy.c
    

    概要
    

    
    警告
    
      
    サーバを安全にするまで ProxyRequests は有効にしないでください。
      オープンプロキシサーバはあなた自身のネットワークにとっても、
      インターネット全体にとっても危険です。
    
    
    

    
    このモジュールは Apache のプロキシ/ゲートウェイ機能を実装しています。
    AJP13 (Apache JServe Protocol version 1.3),
    FTP, CONNECT (SSL 用),
    HTTP/0.9, HTTP/1.0, HTTP/1.1
    のプロキシ機能を実装しています。これらのプロトコルやその他のプロトコル用の
    プロキシ機能を持った、他のモジュールに接続するようにも設定できます。
    

    
    Apache のプロキシ機能は mod_proxy の他に、
    いくつかのモジュールに分割されています:
    mod_proxy_http, mod_proxy_ftp,
    mod_proxy_ajp, mod_proxy_balancer, 
    mod_proxy_connect です。ですから、
    特定のプロキシの機能を使いたい場合は、mod_proxy と
    該当するモジュールをサーバに (コンパイル時に静的に行なうか
    LoadModule で動的に読み込むかして) 
    組み込む必要があります。
    

    
    これに加えて、他のモジュールによって拡張機能が提供されています。
    キャッシュは mod_cache と関連モジュールで
    提供されています。SSL/TLS で遠隔サーバに接続する機能は
    mod_ssl の SSLProxy* ディレクティブで
    提供されています。これらの機能を利用するためには、該当するモジュールを
    組み込んで設定しなければなりません。

    フォワードプロキシとリバースプロキシ
    
      
    Apache はフォワードプロキシとしても、
      リバースプロキシとしても設定することができます。
    

      
    通常のフォワードプロキシはクライアントと
      オリジンサーバ (訳注: コンテンツ生成元のサーバ)
      の間に位置する中間サーバです。
      オリジンサーバからコンテンツを取得する過程では、クライアントは
      行き先としてオリジンサーバを指定しつつプロキシにリクエストを送り、
      プロキシはオリジンサーバからコンテンツ取得のリクエストを送り、
      コンテンツが取得できればそれをクライアントに返します。
      クライアントが他のサイトにフォワードプロクシ経由でアクセスするには、
      特別にそれ用の設定をしなければなりません。
    

      
    フォワードプロキシの一般的な使用方法は、ファイアウォールによって
      制限されている内部のクライアントにインターネットへのアクセスを
      提供するものです。フォワードプロキシはネットワークの使用量を
      減らすために (mod_cache で提供されている) 
      キャッシュ機能を用いることもできます。
    

      
    フォワードプロキシは ProxyRequests ディレクティブで
      有効になります。フォワードプロキシでは、クライアントは本当の身元を
      隠して任意のサイトにアクセスできるようになるため、フォワードプロキシを
      有効にする前に、承認されたクライアントのみがプロキシにアクセスできるように
      サーバを安全にすることが重要です。
    

      
    一方リバースプロキシは、クライアントには普通の
      ウェブサーバのように見えます。クライアント側に特別な設定は必要ありません。
      クライアントはリバースプロキシの名前空間に対して通常のコンテンツへの
      リクエストを行ないます。プロキシはリクエストをどこに送れば良いかを判定し、
      あたかも自分自身がオリジンサーバであったかのようにクライアントに
      コンテンツを返します。
    

      
    リバースプロキシのよくある利用方法は、インターネットユーザに
      ファイアウォールの中にあるサーバにアクセスを与えるというものです。
      リバースプロキシは複数のバックエンドサーバへ負荷分散をするために
      使ったり、遅いバックエンドエンドサーバのためにキャッシュ機能を提供したり
      するために使えます。また、リバースプロキシは複数のサーバを
      同じ URL 空間にまとめるために使うこともできます。
    

      
    リバースプロキシは ProxyPass ディレクティブや
      RewriteRule ディレクティブの
      [P] フラグを使うことで有効になります。リバースプロキシの
      設定のために ProxyRequests を設定する必要は
      ありません。

    基本の例
    

    
    以下の例は手始めの簡単な例です。個々のディレクティブの意味は
    それぞれの説明をお読みください。
    

    
    またキャッシュ機能を有効にしたい場合は、mod_cache 
    の説明を読んでください。
    

    
    フォワードプロキシ
    
    ProxyRequests On
    
    ProxyVia On
    
    
    
    <Proxy *>
    
    
      Order deny,allow
    
      Deny from all
    
      Allow from internal.example.com
    
        
    </Proxy>
    
    

    
    リバースプロキシ
    
    ProxyRequests Off
    
    
    
    <Proxy *>
    
    
      Order deny,allow
    
      Allow from all
    
        
    </Proxy>
    
    
    
    ProxyPass /foo http://foo.example.com/bar
    
    ProxyPassReverse /foo http://foo.example.com/bar
    
    
    
    top
    

    

    プロキシへのアクセス制御
    
      
    プロキシのアクセスは以下のように <Proxy> コンテナの中に
      ディレクティブを書くことで制御できます:
    

      
    
        <Proxy *>
    
        
          Order Deny,Allow
    
          Deny from all
    
          Allow from 192.168.0
    
            
        </Proxy>
      
    

      
    アクセス制御のためのディレクティブのより詳しい情報は
      mod_authz_host をお読みください。
    

      
    (ProxyRequests ディレクティブを
      使って) フォワードプロキシを設定している場合は、厳しくアクセス
      制限を行なうことが非常に大切です。そうしないと、任意のクライアントが
      身元を明かすことなく任意のホストにアクセスするためにサーバを使うことが
      できてしまいます。これはあなた自身のネットワークにとっても、インターネット
      全体にとっても危険なことです。(ProxyRequests Off にして
      ProxyPass ディレクティブを使って)
      リバースプロキシを使っている場合には、クライアントはあなたが明示的に
      設定したホストにしかアクセスできないため、フォワードプロキシのとき
      ほどアクセス制御に力を注がなくても大丈夫です。
    

    
    top
    

    

    遅い起動
    
      
    ProxyBlock ディレクティブを使っている場合、
      後のテストのために起動時にホストの
      IP アドレスが調べられてキャッシュされます。ホスト名のルックアップの
      速さによっては、数秒 (かそれ以上) かかるかもしれません。
    
    
    top
    

    

    イントラネットプロキシ
    
      
    イントラネットにある Apache プロキシサーバは外部へのリクエストを
      会社のファイアウォールを通して送らなければなりません。(このためには
      個々の scheme についてそれぞれ、ファイアウォールの
      プロキシにフォワードされるように
      ProxyRemote ディレクティブを
      設定してください)。しかしイントラネット内のリソースにアクセスするときは、
      ファイアウォールを通さないでもアクセスできます。
      どのホストがイントラネットに属し、直接アクセスすべきかを指定するには、
      NoProxy ディレクティブが
      役に立ちます。
    

      
    イントラネット内のユーザは WWW のリクエストでローカルドメインを
      省略することがよくあります。http://somehost.example.com/ 
      というリクエストの代わりに "http://somehost/" をリクエストしたりします。
      このようなリクエストを受け付け、サーバに設定されているローカルドメインが
      暗黙のうちに使われていると解釈して、単純にリクエストを処理するものも
      商用プロキシサーバの中にはあります。
      サーバが プロキシのサービス用に設定されていて
      ProxyDomain ディレクティブが
      使用された場合には、Apache はクライアントにリダイレクト応答を送って、
      正しい、完全な ((訳注: fully qualified)) 
      サーバのアドレスに送ることができます。このように
      リダイレクトすると、ユーザのブックマークが正しい完全なホスト名を含む
      ことにもなるため、より好ましい方法と言えるでしょう。
    
    
    top
    

    

    プロトコルの調整
    
      
    Keepalive や HTTP/1.1 を適切に実装していないアプリケーションサーバに対して
      mod_proxy がリクエストを送信する場合、
      HTTP/1.0 を使って keepalive を無しにしてリクエストを送るようにする
      環境変数が二つあります。これらは SetEnv ディレクティブで設定します。
    

      
    force-proxy-request-1.0 と proxy-nokeepalive
      がその環境変数です。
    

      
    
        <Location /buggyappserver/>
    
        
          ProxyPass http://buggyappserver:7001/foo/
    
          SetEnv force-proxy-request-1.0 1
    
          SetEnv proxy-nokeepalive 1
    
            
        </Location>
      
    

    
    top
    

    

    リクエストボディ
    

    
    POST メソッドなどのリクエストには、リクエストボディがあります。
    HTTP プロトコル仕様によると、ボディのあるリクエストは chunked 
    転送を使うか、Content-Length
    ヘッダを送信しなければなりません。
    このようなリクエストをオリジンサーバに送信する場合、
    mod_proxy_http は常に Content-Length
    を送ろうと試みます。しかし。ボディが大きく、オリジナルのリクエストで
    chunked 転送が使われている場合、上流へのリクエストに
    chunked 転送も使われます。
    この挙動は 環境変数で制御できます。
    proxy-sendcl を設定すると、可能な限り常に 
    Content-Length を付与して、
    上流サーバに送信するようになります。
    逆に proxy-sendchunked を設定すると、リソース消費を抑え、
    chnked エンコードを使って送信するようになります。

    ステータス:Extension
    

    モジュール:mod_proxy
    

    
    
    このディレクティブはイントラネット中の Apache プロキシサーバにのみ
    有用です。NoProxy ディレクティブは空白区切りで、
    サブネット、IP アドレス、ホスト、ドメインのリストを指定します。
    これらのどれかにマッチするホストへのリクエストは ProxyRemote で設定されたプロキシサーバに
    フォワードされず、直接処理されます。
    

    
    例
    
      ProxyRemote  *  http://firewall.mycompany.com:81
    
      NoProxy         .mycompany.com 192.168.112.0/21
    
    

    
    NoProxy ディレクティブの host 引数は
    以下の種類のどれかです:
    

    
    
    
    
    Domain
    
    
    
    
    Domain は先頭にピリオドの着いた部分 DNS ドメイン名です。
    同一 DNS ドメイン及びゾーン (すなわち、ホスト名の末尾がすべて
    Domain で終わっているということ) に属するホストのリストを
    表します)。
    

    
    例
    
      .com .apache.org.
    
    

    
    Domain を Hostname と区別するために (意味的にも構文的にも。DNS ドメインも
    DNS の A レコードを持つことができるのです!)、Domain は
    常にピリオドで始まります。
    
    
    
    注
    
      
    ドメイン名の比較は大文字小文字を区別せずに行なわれ、Domain
      は常に DNS ツリーのルートから始まるものとみなされます。ですから、
      次の二つのドメイン .MyDomain.com と
      .mydomain.com. (最後のピリオドに注目) は同一であると
      みなされます。ドメインの比較は DNS ルックアップなしで行なわれるため、
      サブネットの比較よりもずっと効率的です。
    
    
    

    
    
    SubNet
    
    
    
    
    SubNet は数値形式 (ドットで区切られた四つの数字) の
    部分インターネットアドレスです。後にスラッシュと Subnet
    の意味のあるビット数を指定するネットマスクとを続けることができます。
    共通のネットワークインタフェースを使って到達することのできるサブネットを
    表すために使われます。明示的にネットマスクを指定しない場合は
    最後の省略された (もしくは値が 0 の) 数字がマスクを指定します。
    (この場合は、ネットマスクは 8 ビット単位でしか指定できません。)
    例:
    

    
    
    
    192.168 もしくは 192.168.0.0
    
    
    サブネット 192.168.0.0 と暗黙の 16 ビット有効なネットマスク
    (255.255.0.0 というネットマスクの形式で使われることも
    あります)
    
    
    192.168.112.0/21
    
    
    サブネット192.168.112.0/21 と 21 ビット有効な
    ネットマスク (255.255.248.0 という形式で使われることも
    あります)
    
    
    

    
    特別な場合に、32 ビット有効な SubNet は
    IPAddr と同等で、
    0 ビット有効な SubNet (例えば、0.0.0.0/0) は
    すべての IP アドレスにマッチする定数 _Default_ と同じです。
    
    
    

    
    
    IPAddr
    
    
    
    
    IPAddr は数値形式 (ドットで区切られた四つの数字) の
    完全インターネットアドレスです。通常はこのアドレスはホストを
    表しますが、必ずしもアドレスに対応する DNS ドメイン名があるわけでは
    ありません。
    

    
    例
    
      192.168.123.7
    
    
    
    
    注
    
      
    IPAddr は DNS システムにより解決される必要がないので、
      apache の性能が向上するかもしれません。
    
    
    

    
    
    Hostname
    
    
    
    
    Hostname は DNS ドメインサービスにより一つもしくは
    複数の IPAddr に解決可能な
    完全な DNS ドメイン名です。これは (Domain
    と違って、説明は上記を参照) 論理的なホストを表し、少くとも一つの
    IPAddr (もしくは違う
    IPAddr のホストのリスト) に解決
    されなければなりません)。
    

    
    例
    
      prep.ai.mit.edu
    
      www.apache.org
    
    

    
    注
    
      
    多くの場合、Hostname の代わりに IPAddr を指定した方が、DNS ルックアップを
      避けることができるため、効率が良くなります。Apache の名前解決は
      ネームサーバへの接続が遅い PPP 上の場合などにかなり時間を取られる
      ことがあります。
    
      
    Hostname の比較は大文字小文字を区別せずに行なわれ、
      Hostname は常に DNS ツリーのルートから始まるものとみなされます。
      ですから、二つのドメイン WWW.MyDomain.com と
      www.mydomain.com. (最後のピリオドに注目) は同一であると
      みなされます。

    ProxyMaxForwards ディレクティブは
    リクエストに Max-Forwards ヘッダが指定されていない場合に
    リクエストが通過可能なプロキシの最大数を設定します。これは
    プロキシの無限ループや DoS 攻撃を防ぐために設定されています。

    ProxyPass ディレクティブ
    

    

    説明:リモートサーバをローカルサーバの URL 空間にマップする
    

    構文:ProxyPass [path] !|url [key=value key=value ...]]
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ
    

    ステータス:Extension
    

    モジュール:mod_proxy
    

    
    
    このディレクティブはリモートサーバをローカルサーバの名前空間に
    マップできるようにします。ローカルサーバは通常の意味でのプロキシと
    しては動作せず、リモートサーバのミラーとして振る舞います。
    path はローカルの仮想パスの名前です。url は
    リモートサーバの部分 URL になり、クエリー文字列を含むことはできません。
    

    
    ProxyPass ディレクティブを
    使っているときは ProxyRequests ディレクティブは通常は
    off に設定されているべきです。
    

    
    ローカルサーバのアドレスが http://example.com/ であると
    します。すると、
    

    
    
      ProxyPass /mirror/foo/ http://backend.example.com/
    
    

    
    と設定すると http://example.com/mirror/foo/bar への
    リクエストが内部的に http://backend.example.com/bar への
    プロキシリクエストに変換されることになります。
    

    
    サブディレクトリをリバースプロキシしたくないときに ! は
    役に立ちます。例えば、
    

    
    
      ProxyPass /mirror/foo/i !
    
      ProxyPass /mirror/foo http://backend.example.com
    
    

    
    は /mirror/foo/i を除く
    /mirror/foo へのすべてのリクエストを
    backend.example.com にプロキシします。
    

    
    注
    
      
    順番は重要です。一般的な ProxyPass
      ディレクティブの前に
      除外ディレクティブを置く必要があります。
    
    
    

    
    2.1 の機能で、バックエンドサーバとの接続にプールされたコネクションを
    使えるようになりました。key=value 形式のパラメータで
    このコネクションプーリングの調整ができます。Hard Maximum 
    のデフォルト値は、有効になっている MPM でのプロセス当たりのスレッド数と
    同じ数のコネクション数です。prefork MPM では通常は 1 で、worker MPM では
    ThreadsPerChild で調整されます。
    

    
    min の設定で、バックエンドサーバとの間に何本のコネクションを
    常時開くかが決まります。Soft Maximum smax の数に
    達するまで必要に応じてコネクションは生成されます。smax
    を超えた数のコネクションは、生存時間 ttl で切断されます。
    バックエンドサーバと Hard Maximum max の数以上のコネクションを
    生成することはありません。
    

    
    
        ProxyPass /example http://backend.example.com smax=5 max=20 ttl=120 retry=300
    
    

    
    
    
    パラメータ
        デフォルト値
        説明
    
    
    min
        0
        バックエンドサーバとの接続で
            常に開いているコネクション数の最小値
    
    
    max
        1...n
        バックエンドサーバとの接続数の Hard Maximum
        (訳注: ハードリミット)。
        デフォルト値は、使用している MPM のプロセスあたりのスレッド数になっています。
        Prefork MPM では常に 1 で、Worker MPM では ThreadsPerChild
        で調節できます。Hard Maximum 以上にバックエンドサーバとのコネクションを
        生成することはありません。
    
    
    smax
        max
        接続数の Soft Maximum (訳注: ソフトリミット)まで、
        コネクションは必要に応じて生成されます。
        smax を超えた数のコネクションは生存時間 ttl
        で切断されます。
    
    
    
    ttl
        -
        smax 数を超えた非活動状態のコネクションの生存時間を、
        秒で指定します。この期間内に使用されなかったコネクションは、
        全て閉じられます。
    
    
    
    timeout
        Timeout
        コネクションタイムアウトを秒で指定します。特に指定されなければ、
        フリーなコネクションを取得できるまで待ちます。このディレクティブは
        max パラメータと合わせて使うことで、バックエンドサーバとの
        接続数を制御するのに使います。
    
    
    
    acquire
        -
        設定すると、コネクションプールからフリーのコネクションを取得するために
        待機する待ち時間の最大値になります。フリーのコネクションがプールになかった場合は、
        SERVER_BUSY ステータスがクライアントに返されます。
    
    
    
    keepalive
        Off
        バックエンドサーバと Apache の間にファイアーウォールがある場合には、
        このパラメータを使ってください。ファイアウォールは往々にして、
        非活動状態のコネクションを落とそうとします。
        このフラグは OS に指示して、KEEP_ALIVE メッセージを非活動状態の
        コネクションでも送るようにします (間隔は OS のグローバル設定に依存し、
        通常は 120ms 間隔) 。これによってファイアウォールによってコネクションが
        落とされることを防げます。keepalive を有効にするには、このプロパティを
        On にしてください。
    
    
    
    retry
        60
        コネクションをプーリングするための、リトライのタイムアウトを秒で
        指定します。バックエンドサーバへのコネクションプーリングが失敗した場合は、
        タイムアウトの期間が過ぎるまで、そのサーバにリクエストをフォワードしません。
        この機能を使うと、バックエンドサーバをメンテナンスのためにシャットダウンし、
        後でオンラインに復帰させるといったことができます。
    
    
    
    loadfactor
        1
        ワーカーあたりの負荷係数です。BalancerMember で使います。
        1 から 100 までの数字でそのワーカーに対する正規化された負荷率を指定します。
    
    
    
    route
        -
        ロードバランサで使った場合、ワーカーのルーティングをします。
        ルートはセッション ID に付加された値になります。
    
    
    
    redirect
        -
        ワーカーのリダイレクション経路です。この値は通常は、
        安全にクラスタからノードを取り去る設定を動的に入れるために使います。
        セッション ID の無いリクエスト全てを指定した場合は、
        この値と同じルーティングパラメータを持つ 
        BalancerMember にリダイレクトされます。
    
    

    
    

    
    Proxy ディレクティブのスキームが balancer:// になっている場合は、
    バックエンドサーバと実際には通信しない仮想ワーカーが生成されます。
    このワーカーは幾つかの "本物の" ワーカーの管理をつかさどります。
    この場合パラメータは、この仮想ワーカーに対して設定されます。
    
    
    
    
    
    パラメータ
        デフォルト値
        説明
    
    
    lbmethod
        -
        Balancer のロードバランス方法。使用するロードバランスの
        スケジューリング方法を選びます。処理したリクエストの数で重み付けする
        byrequests か、転送量のバイト数で重み付けする
        bytraffic を設定できます。デフォルトは
        byrequests です。
    
    
    
    stickysession
        -
        バランサーのスティッキーセッション名です。通常はこの値は JSESSIONID
        や PHPSESSIONID といったものになりますが、この値は
        バックエンドアプリケーションのサポートするセッションに依存します。
    
    
    
    nofailover
        Off
        On になっていると、ワーカーがエラーを起こしたり
        無効になっている場合にセッションが切れます。
        バックエンドサーバがセッションレプリケーションをサポートしていない場合は、
        On にしてください。
    
    
    
    timeout
        0
        バランサーのタイムアウトを秒で指定します。
        この値を設定すると、フリーのワーカーを取得するまでの最大待機時間になります。
        デフォルトでは待機しません。
    
    
    
    maxattempts
        1
        フェイルオーバーを試みる最大の回数を指定します。
    
    
    
    
    
    
    
      ProxyPass /special-area http://special.example.com/ smax=5 max=10

URL を調整する
    

    構文:ProxyPassReverse [path] url
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ
    

    ステータス:Extension
    

    モジュール:mod_proxy
    

    
    
    このディレクティブは Apache に HTTP リダイレクト応答の
    Location, Content-Location, URI
    ヘッダの調整をさせます。これは、Apache がリバースプロキシとして使われている
    ときに、リバースプロキシを通さないでアクセスすることを防ぐために
    重要です。これによりバックエンドサーバの HTTP リダイレクトが
    リバースプロキシとバックエンドの間で扱われるようになります。
    

    
    ディレクティブで明示されている HTTP 応答ヘッダのみが書き換えられます。
    Apache は他の応答ヘッダを書き換えたり、HTML ページの中の URL 参照を
    書き換えたりすることはありません。HTML の中を見て、URL 参照を書き換える
    モジュールに Nick Kew さんの mod_proxy_html があります。
    

    
    path はローカル仮想パスの名前です。url は
    リモートサーバの部分 URL です。これらは ProxyPass ディレクティブと同様です。
    

    
    例えば、ローカルサーバのアドレスが http://example.com/
    だとします。すると
    

    
    
      ProxyPass         /mirror/foo/ http://backend.example.com/
    
      ProxyPassReverse  /mirror/foo/ http://backend.example.com/
    
      ProxyPassReverseCookieDomain  backend.example.com  public.example.com
    
      ProxyPassReverseCookiePath  /  /mirror/foo/
    
    

    
    という設定をすると、http://example.com/mirror/foo/bar
    へのローカルリクエストが http://backend.example.com/bar
    へのプロキシリクエストに内部でリダイレクトされるだけではありません
    (これは ProxyPass の機能です)。backend.example.com
    が送るリダイレクトの面倒もみます。http://backend.example.com/bar
    が http://backend.example.com/quux にリダイレクトされたとき、
    Apache は HTTP リダイレクト応答をクライアントに送る前に、
    http://example.com/mirror/foo/quux に変更します。
    URL を構成するのに使われるホスト名は UseCanonicalName の設定に応じて選択されることに
    注意してください。
    

    
    ProxyPassReverse ディレクティブは
    対応する ProxyPass ディレクティブには依存しないため、
    mod_rewrite のプロキシ通過機能
    (RewriteRule ...  [P]) と併せて使用することができます。
    

    
    <Location> セクションの中で使われた場合は、
    最初の引数は省略され、ローカルディレクトリは <Location> から取得されます。

    で指定したホスト名の代わりに、受け付けたリクエストの Host: 行を
    プロキシ先のホストに送ります。
    

    
    このオプションは通常は Off に設定してください。
    ほとんどの場合、これは大量の名前ベースのバーチャルホスティングを行なっていて、
    元々の Host ヘッダをバックエンドサーバが解釈する必要のあるときのような、
    特別な設定が必要な場合にのみ有用です。

    モジュール:mod_proxy
    

    
    
    このディレクティブはこのプロキシに対するリモートプロキシを定義します。
    match はリモートサーバがサポートする URL スキーム、
    リモートサーバが使うはずの URL の一部分、サーバがすべての
    リクエストに使われることを示す * のどれかになります。
    remote-server はリモートサーバの部分 URL です。構文:
    

    
    
      remote-server =
          scheme://hostname[:port]
    
    

    
    scheme は実際上リモートサーバとの通信に使われるプロトコルを
    決定します。このモジュールでは http だけがサポートされて
    います。
    

    
    例
    
      ProxyRemote http://goodguys.com/ http://mirrorguys.com:8000
    
      ProxyRemote * http://cleversite.com
    
      ProxyRemote ftp http://ftpproxy.mydomain.com:8080
    
    

    
    この例では、プロキシは FTP リクエストを別の HTTP リクエストで包んで
    そのようなリクエストを扱える別のプロキシに転送します。
    

    
    このオプションはリバースプロキシの設定もサポートします。
    サーバが別のフォワードプロキシの後ろに隠されている場合でも
    バックエンドウェブサーバをバーチャルホストの URL 空間に入れることが
    できます。

    Apache Module mod_cgid
    

    

    Available Languages:  en  |
 fr  |

    Description:Execution of CGI scripts using an
    external CGI daemon
    

    Status:Base
    

    Module Identifier:cgid_module
    

    Source File:mod_cgid.c
    

    Compatibility:Unix threaded MPMs only
    

    Summary
    

    
    Except for the optimizations and the additional ScriptSock directive noted below,
    mod_cgid behaves similarly to mod_cgi.
    See the mod_cgi summary for additional details
    about Apache and CGI.
    

    
    On certain unix operating systems, forking a process from a
    multi-threaded server is a very expensive operation because the
    new process will replicate all the threads of the parent
    process. In order to avoid incurring this expense on each CGI
    invocation, mod_cgid creates an external daemon that is
    responsible for forking child processes to run CGI scripts. The
    main server communicates with this daemon using a unix domain
    socket.
    

    
    This module is used by default instead of
    mod_cgi whenever a multi-threaded MPM
    is selected during the compilation process. At the user level,
    this module is identical in configuration and operation to
    mod_cgi. The only exception is the
    additional directive ScriptSock which gives the
    name of the socket to use for communication with the cgi
    daemon.

    CGIDScriptTimeout Directive
    

    

    Description:The length of time to wait for more output from the
CGI program
    

    Syntax:CGIDScriptTimeout time[s|ms]
    

    Default:value of Timeout directive when 
unset or set to 0
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Base
    

    Module:mod_cgid
    

    Compatibility:Available in httpd 2.4.10 and later; in prior releases no timeout was applied
    

    
    
    This directive limits the length of time to wait for more output from
    the CGI program.  If the time is exceeded, the request and CGI are 
    terminated.
    

    
    Example
    CGIDScriptTimeout 20
    

    



    

    top
    

    ScriptSock Directive
    

    

    Description:The filename prefix of the socket to use for communication with
the cgi daemon
    

    Syntax:ScriptSock file-path
    

    Default:ScriptSock cgisock
    

    Context:server config
    

    Status:Base
    

    Module:mod_cgid
    

    
    
    This directive sets the filename prefix of the socket to use for
    communication with the CGI daemon, an extension corresponding to
    the process ID of the server will be appended. The socket will be opened
    using the permissions of the user who starts Apache (usually
    root). To maintain the security of communications with CGI
    scripts, it is important that no other user has permission to
    write in the directory where the socket is located.
    

    
    If file-path is not an absolute path, the location specified
    will be relative to the value of 
    DefaultRuntimeDir.
    

    
    Example
    ScriptSock /var/run/cgid.sock

    Environment Variables
    


    This module can be configured to provide several items of SSL information
as additional environment variables to the SSI and CGI namespace. Except for
HTTPS and SSL_TLS_SNI which are always defined, this
information is not provided by default for performance reasons. (See
SSLOptions StdEnvVars, below)
The generated variables
are listed in the table below. For backward compatibility the information can
be made available under different names, too. Look in the Compatibility chapter for details on the
compatibility variables.

    x509 specifies a component of an X.509 DN; one of
C,ST,L,O,OU,CN,T,I,G,S,D,UID,Email.  In httpd 2.2.0 and
later, x509 may also include a numeric _n
suffix.  If the DN in question contains multiple attributes of the
same name, this suffix is used as a zero-based index to select a
particular attribute.  For example, where the server certificate
subject DN included two OU attributes, SSL_SERVER_S_DN_OU_0
and
SSL_SERVER_S_DN_OU_1 could be used to reference each.  A
variable name without a _n suffix is equivalent to that
name with a _0 suffix; the first (or only) attribute.
When the environment table is populated using
the StdEnvVars option of
the SSLOptions directive, the
first (or only) attribute of any DN is added only under a non-suffixed
name; i.e. no _0 suffixed entries are added.
    


    In httpd 2.4.32 and later, an optional _RAW suffix may be
added to x509 in a DN component, to suppress conversion of
the attribute value to UTF-8. This must be placed after the index
suffix (if any). For example, SSL_SERVER_S_DN_OU_RAW or
SSL_SERVER_S_DN_OU_0_RAW could be used.
    


    The format of the *_DN variables has changed in Apache HTTPD
2.3.11. See the LegacyDNStringFormat option for
SSLOptions for details.
    


    SSL_CLIENT_V_REMAIN is only available in version 2.1
and later.
    


    A number of additional environment variables can also be used
in SSLRequire expressions, or in custom log
formats:
    


    HTTP_USER_AGENT        PATH_INFO             AUTH_TYPE
HTTP_REFERER           QUERY_STRING          SERVER_SOFTWARE
HTTP_COOKIE            REMOTE_HOST           API_VERSION
HTTP_FORWARDED         REMOTE_IDENT          TIME_YEAR
HTTP_HOST              IS_SUBREQ             TIME_MON
HTTP_PROXY_CONNECTION  DOCUMENT_ROOT         TIME_DAY
HTTP_ACCEPT            SERVER_ADMIN          TIME_HOUR
THE_REQUEST            SERVER_NAME           TIME_MIN
REQUEST_FILENAME       SERVER_PORT           TIME_SEC
REQUEST_METHOD         SERVER_PROTOCOL       TIME_WDAY
REQUEST_SCHEME         REMOTE_ADDR           TIME
REQUEST_URI            REMOTE_USER
    


    In these contexts, two special formats can also be used:
    


    
  
    ENV:variablename
    
  
    This will expand to the standard environment
  variable variablename.
    

  
    HTTP:headername
    
  
    This will expand to the value of the request header with name
  headername.

    Custom Log Formats
    


    When mod_ssl is built into Apache or at least
loaded (under DSO situation) additional functions exist for the Custom Log Format of
mod_log_config. First there is an
additional ``%{varname}x''
eXtension format function which can be used to expand any variables
provided by any module, especially those provided by mod_ssl which can
you find in the above table.
    

    
For backward compatibility there is additionally a special
``%{name}c'' cryptography format function
provided. Information about this function is provided in the Compatibility chapter.
    

    Example
    CustomLog "logs/ssl_request_log" "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
    

    

    These formats even work without setting the StdEnvVars
option of the SSLOptions
directive.
    

    top
    

    

    Request Notes
    


    mod_ssl sets "notes" for the request which can be
used in logging with the %{name}n format
string in mod_log_config.
    


    The notes supported are as follows:
    


    
  
    ssl-access-forbidden
    
  
    This note is set to the value 1 if access was
  denied due to an SSLRequire
  or SSLRequireSSL directive.
    

  
    ssl-secure-reneg
    
  
    If mod_ssl is built against a version of
  OpenSSL which supports the secure renegotiation extension, this note
  is set to the value 1 if SSL is in used for the current
  connection, and the client also supports the secure renegotiation
  extension.  If the client does not support the secure renegotiation
  extension, the note is set to the value 0.
  If mod_ssl is not built against a version of
  OpenSSL which supports secure renegotiation, or if SSL is not in use
  for the current connection, the note is not set.

    Expression Parser Extension
    


    When mod_ssl is built into Apache or at least
loaded (under DSO situation) any variables
provided by mod_ssl can be used in expressions
for the ap_expr Expression Parser.
The variables can be referenced using the syntax
``%{varname}''. Starting
with version 2.4.18 one can also use the
mod_rewrite style syntax
``%{SSL:varname}'' or
the function style syntax
``ssl(varname)''.
    

    Example (using mod_headers)
    Header set X-SSL-PROTOCOL "expr=%{SSL_PROTOCOL}"
Header set X-SSL-CIPHER "expr=%{SSL:SSL_CIPHER}"
    

    

    This feature even works without setting the StdEnvVars
option of the SSLOptions
directive.

    Authorization providers for use with Require
    

  
    mod_ssl provides a few authentication providers for use
  with mod_authz_core's
  Require directive.
    

  
    Require ssl
    

    
    The ssl provider denies access if a connection is not
       encrypted with SSL. This is similar to the
       SSLRequireSSL directive.
    

    
    Require ssl
    


  

  
    Require ssl-verify-client
    

    
    The ssl provider allows access if the user is
       authenticated with a valid client certificate. This is only
       useful if SSLVerifyClient optional is in effect.
    

    
    The following example grants access if the user is authenticated
       either with a client certificate or by username and password.
    

    
    Require ssl-verify-client
Require valid-user

    SSLCACertificateFile Directive
    

    

    Description:File of concatenated PEM-encoded CA Certificates
for Client Auth
    

    Syntax:SSLCACertificateFile file-path
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive sets the all-in-one file where you can assemble the
Certificates of Certification Authorities (CA) whose clients you deal
with. These are used for Client Authentication. Such a file is simply the
concatenation of the various PEM-encoded Certificate files, in order of
preference. This can be used alternatively and/or additionally to
SSLCACertificatePath.
    

    Example
    SSLCACertificateFile "/usr/local/apache2/conf/ssl.crt/ca-bundle-client.crt"
    

    


    

    top
    

    SSLCACertificatePath Directive
    

    

    Description:Directory of PEM-encoded CA Certificates for
Client Auth
    

    Syntax:SSLCACertificatePath directory-path
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive sets the directory where you keep the Certificates of
Certification Authorities (CAs) whose clients you deal with. These are used to
verify the client certificate on Client Authentication.
    

    
The files in this directory have to be PEM-encoded and are accessed through
hash filenames. So usually you can't just place the Certificate files
there: you also have to create symbolic links named
hash-value.N. And you should always make sure this directory
contains the appropriate symbolic links.
    

    Example
    SSLCACertificatePath "/usr/local/apache2/conf/ssl.crt/"

    When a client certificate is requested by mod_ssl, a list of
acceptable Certificate Authority names is sent to the client
in the SSL handshake.  These CA names can be used by the client to
select an appropriate client certificate out of those it has
available.
    


    If neither of the directives SSLCADNRequestPath or SSLCADNRequestFile are given, then the
set of acceptable CA names sent to the client is the names of all the
CA certificates given by the SSLCACertificateFile and SSLCACertificatePath directives; in other
words, the names of the CAs which will actually be used to verify the
client certificate.
    


    In some circumstances, it is useful to be able to send a set of
acceptable CA names which differs from the actual CAs used to verify
the client certificate - for example, if the client certificates are
signed by intermediate CAs.  In such cases, SSLCADNRequestPath and/or SSLCADNRequestFile can be used; the
acceptable CA names are then taken from the complete set of
certificates in the directory and/or file specified by this pair of
directives.
    


    SSLCADNRequestFile must
specify an all-in-one file containing a concatenation of
PEM-encoded CA certificates.

    SSLCADNRequestFile "/usr/local/apache2/conf/ca-names.crt"

    The files in this directory have to be PEM-encoded and are accessed
through hash filenames. So usually you can't just place the
Certificate files there: you also have to create symbolic links named
hash-value.N. And you should always make sure
this directory contains the appropriate symbolic links.

Enables certificate revocation list (CRL) checking. At least one of
SSLCARevocationFile
or SSLCARevocationPath must be
configured. When set to chain (recommended setting),
CRL checks are applied to all certificates in the chain, while setting it to
leaf limits the checks to the end-entity cert.

    

    The available flags are:
    

      

    • no_crl_for_cert_ok
    
      
    Prior to version 2.3.15, CRL checking in mod_ssl also succeeded when
    no CRL(s) for the checked certificate(s) were found in any of the locations
    configured with SSLCARevocationFile
    or SSLCARevocationPath.
    
      
    
      
    With the introduction of SSLCARevocationFile,
    the behavior has been changed: by default with chain or
    leaf, CRLs must be present for the
    validation to succeed - otherwise it will fail with an
    "unable to get certificate CRL" error.
    
      
    
      
    The flag no_crl_for_cert_ok allows to restore
    previous behaviour.

    SSLCertificateChainFile is deprecated
    

    SSLCertificateChainFile became obsolete with version 2.4.8,
when SSLCertificateFile
was extended to also load intermediate CA certificates from the server
certificate file.
    

    


    
This directive sets the optional all-in-one file where you can
assemble the certificates of Certification Authorities (CA) which form the
certificate chain of the server certificate. This starts with the issuing CA
certificate of the server certificate and can range up to the root CA
certificate. Such a file is simply the concatenation of the various
PEM-encoded CA Certificate files, usually in certificate chain order.
    

    
This should be used alternatively and/or additionally to SSLCACertificatePath for explicitly
constructing the server certificate chain which is sent to the browser
in addition to the server certificate. It is especially useful to
avoid conflicts with CA certificates when using client
authentication. Because although placing a CA certificate of the
server certificate chain into SSLCACertificatePath has the same effect
for the certificate chain construction, it has the side-effect that
client certificates issued by this same CA certificate are also
accepted on client authentication.
    

    
But be careful: Providing the certificate chain works only if you are using a
single RSA or DSA based server certificate. If you are
using a coupled RSA+DSA certificate pair, this will work only if actually both
certificates use the same certificate chain. Else the browsers will be
confused in this situation.

    SSLCertificateChainFile "/usr/local/apache2/conf/ssl.crt/ca.crt"

This directive points to a file with certificate data in PEM format, or the certificate identifier through a configured cryptographic token.
If using a PEM file, at minimum, the file must include an end-entity (leaf) certificate.
The directive can be used multiple times (referencing different filenames)
to support multiple algorithms for server authentication - typically
RSA, DSA, and ECC. The number of supported algorithms depends on the
OpenSSL version being used for mod_ssl: with version 1.0.0 or later,
openssl list-public-key-algorithms will output a list
of supported algorithms, see also the note below about limitations
of OpenSSL versions prior to 1.0.2 and the ways to work around them.

    


    
The files may also include intermediate CA certificates, sorted from
leaf to root. This is supported with version 2.4.8 and later,
and obsoletes SSLCertificateChainFile.
When running with OpenSSL 1.0.2 or later, this allows
to configure the intermediate CA chain on a per-certificate basis.

    


    
Custom DH parameters and an EC curve name for ephemeral keys,
can also be added to end of the first file configured using
SSLCertificateFile.
This is supported in version 2.4.7 or later.
Such parameters can be generated using the commands
openssl dhparam and openssl ecparam.
The parameters can be added as-is to the end of the first
certificate file. Only the first file can be used for custom
parameters, as they are applied independently of the authentication
algorithm type.

    


    
Finally the end-entity certificate's private key can also be
added to the certificate file instead of using a separate
SSLCertificateKeyFile
directive. This practice is highly discouraged. If it is used,
the certificate files using such an embedded key must be configured
after the certificates using a separate key file. If the private
key is encrypted, the pass phrase dialog is forced at startup time.

    


    As an alternative to storing certificates and private keys in
files, a certificate identifier can be used to identify a certificate
stored in a token.  Currently, only PKCS#11 URIs are
recognized as certificate identifiers, and can be used in conjunction
with the OpenSSL pkcs11 engine.  If SSLCertificateKeyFile is omitted, the
certificate and private key can be loaded through the single
identifier specified with SSLCertificateFile.
    


    

    DH parameter interoperability with primes > 1024 bit
    

    
Beginning with version 2.4.7, mod_ssl makes use of
standardized DH parameters with prime lengths of 2048, 3072 and 4096 bits
and with additional prime lengths of 6144 and 8192 bits beginning with
version 2.4.10
(from RFC 3526), and hands
them out to clients based on the length of the certificate's RSA/DSA key.
With Java-based clients in particular (Java 7 or earlier), this may lead
to handshake failures - see this
FAQ answer for working around
such issues.

    

    


    

    Default DH parameters when using multiple certificates and OpenSSL
versions prior to 1.0.2
    

    
When using multiple certificates to support different authentication algorithms
(like RSA, DSA, but mainly ECC) and OpenSSL prior to 1.0.2, it is recommended
to either use custom DH parameters (preferably) by adding them to the
first certificate file (as described above), or to order the
SSLCertificateFile directives such that RSA/DSA
certificates are placed after the ECC one.

    

    
This is due to a limitation in older versions of OpenSSL which don't let the
Apache HTTP Server determine the currently selected certificate at handshake
time (when the DH parameters must be sent to the peer) but instead always
provide the last configured certificate. Consequently, the server may select
default DH parameters based on the length of the wrong certificate's key (ECC
keys are much smaller than RSA/DSA ones and their length is not relevant for
selecting DH primes).

    

    
Since custom DH parameters always take precedence over the default ones, this
issue can be avoided by creating and configuring them (as described above),
thus using a custom/suitable length.

    

    


    Example
    # Example using a PEM-encoded file.

This directive points to the PEM-encoded private key file for the

The directive can be used multiple times (referencing different filenames)
to support multiple algorithms for server authentication. For each
SSLCertificateKeyFile
directive, there must be a matching SSLCertificateFile
directive.
    


    
The private key may also be combined with the certificate in the file given by
SSLCertificateFile, but this practice
is highly discouraged. If it is used, the certificate files using such
an embedded key must be configured after the certificates using a separate
key file.
    


    As an alternative to storing private keys in files, a key

This complex directive uses a colon-separated cipher-spec string
consisting of OpenSSL cipher specifications to configure the Cipher Suite the
client is permitted to negotiate in the SSL handshake phase. The optional 
protocol specifier can configure the Cipher Suite for a specific SSL version.
Possible values include "SSL" for all SSL Protocols up to and including TLSv1.2.

    

    
Notice that this
directive can be used both in per-server and per-directory context. 
In per-server context it applies to the standard SSL handshake when a connection
is established. In per-directory context it forces a SSL renegotiation with the
reconfigured Cipher Suite after the HTTP request was read but before the HTTP
response is sent.
    

    
If the SSL library supports TLSv1.3 (OpenSSL 1.1.1 and later), the protocol 
specifier "TLSv1.3" can be used to configure the cipher suites for that protocol.
Since TLSv1.3 does not offer renegotiations, specifying ciphers for it in
a directory context is not allowed.
    

    
For a list of TLSv1.3 cipher names, see 
the OpenSSL
documentation.
    

    
An SSL cipher specification in cipher-spec is composed of 4 major
attributes plus a few extra minor ones:
    

      

    • Key Exchange Algorithm:
      
    RSA, Diffie-Hellman, Elliptic Curve Diffie-Hellman, Secure Remote Password

      • 

    • Authentication Algorithm:
      
    RSA, Diffie-Hellman, DSS, ECDSA, or none.

      • 

    • Cipher/Encryption Algorithm:
      
    AES, DES, Triple-DES, RC4, RC2, IDEA, etc.

      • 

    • MAC Digest Algorithm:
      
    MD5, SHA or SHA1, SHA256, SHA384.

      • 

    

    An SSL cipher can also be an export cipher. SSLv2 ciphers are no longer
supported. To specify which ciphers to use, one can either specify all the
Ciphers, one at a time, or use aliases to specify the preference and order
for the ciphers (see Table
1). The actually available ciphers and aliases depends on the used
openssl version. Newer openssl versions may include additional ciphers.

Now where this becomes interesting is that these can be put together
to specify the order and ciphers you wish to use. To speed this up
there are also aliases (SSLv3, TLSv1, EXP, LOW, MEDIUM,
HIGH) for certain groups of ciphers. These tags can be joined
together with prefixes to form the cipher-spec. Available
prefixes are:
    

      

    • none: add cipher to list
      • 

    • +: move matching ciphers to the current location in list
      • 

    • -: remove cipher from list (can be added later again)
      • 

    • !: kill cipher from list completely (can not be added later again)
      • 

    


    

    aNULL, eNULL and EXP
ciphers are always disabled
    

    Beginning with version 2.4.7, null and export-grade
ciphers are always disabled, as mod_ssl unconditionally adds
!aNULL:!eNULL:!EXP to any cipher string at initialization.
    

    


    A simpler way to look at all of this is to use the ``openssl ciphers
-v'' command which provides a nice way to successively create the
correct cipher-spec string. The default cipher-spec string
depends on the version of the OpenSSL libraries used. Let's suppose it is
``RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5'' which
means the following: Put RC4-SHA and AES128-SHA at
the beginning. We do this, because these ciphers offer a good compromise
between speed and security. Next, include high and medium security ciphers.
Finally, remove all ciphers which do not authenticate, i.e. for SSL the
Anonymous Diffie-Hellman ciphers, as well as all ciphers which use
MD5 as hash algorithm, because it has been proven insufficient.
    

    $ openssl ciphers -v 'RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5'
RC4-SHA                 SSLv3 Kx=RSA      Au=RSA  Enc=RC4(128)  Mac=SHA1

    This directive allows to enable compression on the SSL level.

This directive enables use of a cryptographic hardware accelerator
board to offload some of the SSL processing overhead.  This directive
can only be used if the SSL toolkit is built with "engine" support;
OpenSSL 0.9.7 and later releases have "engine" support by default, the
separate "-engine" releases of OpenSSL 0.9.6 must be used.
    


    To discover which engine names are supported, run the command
"openssl engine".

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive toggles the usage of the SSL/TLS Protocol Engine. This
is should be used inside a <VirtualHost> section to enable SSL/TLS for a
that virtual host. By default the SSL/TLS Protocol Engine is
disabled for both the main server and all configured virtual hosts.
    

    Example
    <VirtualHost _default_:443>
SSLEngine on
#...
</VirtualHost>
    

    

    In Apache 2.1 and later, SSLEngine can be set to
optional. This enables support for
RFC 2817, Upgrading to TLS
Within HTTP/1.1. At this time no web browsers support RFC 2817.

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive toggles the usage of the SSL library FIPS_mode flag.
It must be set in the global server context and cannot be configured
with conflicting settings (SSLFIPS on followed by SSLFIPS off or
similar).  The mode applies to all SSL library operations.

    

    
If httpd was compiled against an SSL library which did not support
the FIPS_mode flag, SSLFIPS on will fail.  Refer to the
FIPS 140-2 Security Policy document of the SSL provider library for
specific requirements to use mod_ssl in a FIPS 140-2 approved mode
of operation; note that mod_ssl itself is not validated, but may be
described as using FIPS 140-2 validated cryptographic module, when
all components are assembled and operated under the guidelines imposed
by the applicable Security Policy.

    As originally specified, all versions of the SSL and TLS protocols
(up to and including TLS/1.2) were vulnerable to a Man-in-the-Middle
attack
(CVE-2009-3555)
during a renegotiation.  This vulnerability allowed an attacker to
"prefix" a chosen plaintext to the HTTP request as seen by the web
server.  A protocol extension was developed which fixed this
vulnerability if supported by both client and server.
    


    If mod_ssl is linked against OpenSSL version 0.9.8m
or later, by default renegotiation is only supported with
clients supporting the new protocol extension.  If this directive is
enabled, renegotiation will be allowed with old (unpatched) clients,
albeit insecurely.
    


    Security warning
    

    If this directive is enabled, SSL connections will be vulnerable to
the Man-in-the-Middle prefix attack as described
in CVE-2009-3555.
    

    


    Example
    SSLInsecureRenegotiation on
    

    


    The SSL_SECURE_RENEG environment variable can be used
from an SSI or CGI script to determine whether secure renegotiation is
supported for a given SSL connection.

    This option enables OCSP validation of the client certificate
chain.  If this option is enabled, certificates in the client's
certificate chain will be validated against an OCSP responder after
normal verification (including CRL checks) have taken place. In 
mode 'leaf', only the client certificate itself will be validated.
    


    The OCSP responder used is either extracted from the certificate
itself, or derived by configuration; see the
SSLOCSPDefaultResponder and

    Compatibility:Available in httpd 2.4.8 and later, if using OpenSSL 1.0.2 or later
    

    

    This directive exposes OpenSSL's SSL_CONF API to mod_ssl,
allowing a flexible configuration of OpenSSL parameters without the need
of implementing additional mod_ssl directives when new
features are added to OpenSSL.
    


    The set of available SSLOpenSSLConfCmd commands
depends on the OpenSSL version being used for mod_ssl
(at least version 1.0.2 is required). For a list of supported command
names, see the section Supported configuration file commands in the
SSL_CONF_cmd(3) manual page for OpenSSL.
    


    Some of the SSLOpenSSLConfCmd commands can be used
as an alternative to existing directives (such as
SSLCipherSuite or
SSLProtocol),
though it should be noted that the syntax / allowable values for the parameters
may sometimes differ.

    SSLOptions Directive
    

    

    Description:Configure various SSL engine run-time options

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive can be used to control various run-time options on a
per-directory basis. Normally, if multiple SSLOptions
could apply to a directory, then the most specific one is taken
completely; the options are not merged. However if all the
options on the SSLOptions directive are preceded by a
plus (+) or minus (-) symbol, the options
are merged. Any options preceded by a + are added to the
options currently in force, and any options preceded by a
- are removed from the options currently in force.
    

    
The available options are:
    

      

    • StdEnvVars
    
      
    When this option is enabled, the standard set of SSL related CGI/SSI
    environment variables are created. This per default is disabled for
    performance reasons, because the information extraction step is a
    rather expensive operation. So one usually enables this option for
    CGI and SSI requests only.
      

      • 

    • ExportCertData
    
      
    When this option is enabled, additional CGI/SSI environment variables are
    created: SSL_SERVER_CERT, SSL_CLIENT_CERT and
    SSL_CLIENT_CERT_CHAIN_n (with n = 0,1,2,..).
    These contain the PEM-encoded X.509 Certificates of server and client for
    the current HTTPS connection and can be used by CGI scripts for deeper
    Certificate checking. Additionally all other certificates of the client
    certificate chain are provided, too. This bloats up the environment a
    little bit which is why you have to use this option to enable it on
    demand.
      

      • 

    • FakeBasicAuth
    
      
    When this option is enabled, the Subject Distinguished Name (DN) of the
    Client X509 Certificate is translated into a HTTP Basic Authorization
    username. This means that the standard Apache authentication methods can
    be used for access control. The user name is just the Subject of the
    Client's X509 Certificate (can be determined by running OpenSSL's
    openssl x509 command: openssl x509 -noout -subject -in
    certificate.crt). Note that no password is
    obtained from the user. Every entry in the user file needs this password:
    ``xxj31ZMTZzkVA'', which is the DES-encrypted version of the
    word `password''. Those who live under MD5-based encryption
    (for instance under FreeBSD or BSD/OS, etc.) should use the following MD5
    hash of the same word: ``$1$OXLyS...$Owx8s2/m9/gfkcRVXzgoE/''.
      

    
      Note that the AuthBasicFake
    directive within mod_auth_basic can be used as a more
    general mechanism for faking basic authentication, giving control over the
    structure of both the username and password.
      

      • 

    • StrictRequire
    
      
    This forces forbidden access when SSLRequireSSL or
    SSLRequire successfully decided that access should be
    forbidden. Usually the default is that in the case where a ``Satisfy
    any'' directive is used, and other access restrictions are passed,
    denial of access due to SSLRequireSSL or
    SSLRequire is overridden (because that's how the Apache
    Satisfy mechanism should work.) But for strict access restriction
    you can use SSLRequireSSL and/or SSLRequire in
    combination with an ``SSLOptions +StrictRequire''. Then an
    additional ``Satisfy Any'' has no chance once mod_ssl has
    decided to deny access.
      

      • 

    • OptRenegotiate
    
      
    This enables optimized SSL connection renegotiation handling when SSL
    directives are used in per-directory context. By default a strict
    scheme is enabled where every per-directory reconfiguration of
    SSL parameters causes a full SSL renegotiation handshake. When this
    option is used mod_ssl tries to avoid unnecessary handshakes by doing more
    granular (but still safe) parameter checks. Nevertheless these granular
    checks sometimes may not be what the user expects, so enable this on a
    per-directory basis only, please.
      

      • 

    • LegacyDNStringFormat
    
      
    This option influences how values of the
    SSL_{CLIENT,SERVER}_{I,S}_DN variables are formatted. Since
    version 2.3.11, Apache HTTPD uses a RFC 2253 compatible format by
    default. This uses commas as delimiters between the attributes, allows the
    use of non-ASCII characters (which are converted to UTF8), escapes
    various special characters with backslashes, and sorts the attributes
    with the "C" attribute last.
      

    
      If LegacyDNStringFormat is set, the old format will be
    used which sorts the "C" attribute first, uses slashes as separators, and
    does not handle non-ASCII and special characters in any consistent way.

    SSLPassPhraseDialog Directive
    

    

    Description:Type of pass phrase dialog for encrypted private
keys
    

    Syntax:SSLPassPhraseDialog type
    

    Default:SSLPassPhraseDialog builtin
    

    Context:server config
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
When Apache starts up it has to read the various Certificate (see
SSLCertificateFile) and
Private Key (see SSLCertificateKeyFile) files of the
SSL-enabled virtual servers. Because for security reasons the Private
Key files are usually encrypted, mod_ssl needs to query the
administrator for a Pass Phrase in order to decrypt those files. This
query can be done in two ways which can be configured by
type:
    

      

    • builtin
    
      
    This is the default where an interactive terminal dialog occurs at startup
    time just before Apache detaches from the terminal. Here the administrator
    has to manually enter the Pass Phrase for each encrypted Private Key file.
    Because a lot of SSL-enabled virtual hosts can be configured, the
    following reuse-scheme is used to minimize the dialog: When a Private Key
    file is encrypted, all known Pass Phrases (at the beginning there are
    none, of course) are tried. If one of those known Pass Phrases succeeds no
    dialog pops up for this particular Private Key file. If none succeeded,
    another Pass Phrase is queried on the terminal and remembered for the next
    round (where it perhaps can be reused).
      
    
      
    This scheme allows mod_ssl to be maximally flexible (because for N encrypted
    Private Key files you can use N different Pass Phrases - but then
    you have to enter all of them, of course) while minimizing the terminal
    dialog (i.e. when you use a single Pass Phrase for all N Private Key files
    this Pass Phrase is queried only once).
      • 


    • |/path/to/program [args...]

   
      This mode allows an external program to be used which acts as a
   pipe to a particular input device; the program is sent the standard
   prompt text used for the builtin mode on
   stdin, and is expected to write password strings on
   stdout.  If several passwords are needed (or an
   incorrect password is entered), additional prompt text will be
   written subsequent to the first password being returned, and more
   passwords must then be written back.
      • 


    • exec:/path/to/program
    
      
    Here an external program is configured which is called at startup for each
    encrypted Private Key file. It is called with two arguments (the first is
    of the form ``servername:portnumber'', the second is either
    ``RSA'', ``DSA'', ``ECC'' or an
    integer index starting at 3 if more than three keys are configured), which
    indicate for which server and algorithm it has to print the corresponding
    Pass Phrase to stdout. In versions 2.4.8 (unreleased)
    and 2.4.9, it is called with one argument, a string of the
    form ``servername:portnumber:index'' (with index
    being a zero-based integer number), which indicate the server, TCP port
    and certificate number.  The intent is that this external
    program first runs security checks to make sure that the system is not
    compromised by an attacker, and only when these checks were passed
    successfully it provides the Pass Phrase.
      
    
      
    Both these security checks, and the way the Pass Phrase is determined, can
    be as complex as you like. Mod_ssl just defines the interface: an
    executable program which provides the Pass Phrase on stdout.
    Nothing more or less! So, if you're really paranoid about security, here
    is your interface. Anything else has to be left as an exercise to the
    administrator, because local security requirements are so different.
      
    
      
    The reuse-algorithm above is used here, too. In other words: The external
    program is called only once per unique Pass Phrase.

    A new version of the TLS protocol, as defined in
    RFC 8446.
      • 


    • all
    
      
    This is a shortcut for ``+SSLv3 +TLSv1'' or
    - when using OpenSSL 1.0.1 and later -
    ``+SSLv3 +TLSv1 +TLSv1.1 +TLSv1.2'', respectively
    (except for OpenSSL versions compiled with the ``no-ssl3'' configuration
    option, where all does not include +SSLv3).
      • 

    

    Example
    SSLProtocol TLSv1
    

    

    

    SSLProtocol for name-based virtual hosts
    

    
Before OpenSSL 1.1.1, even though the Server Name Indication (SNI) allowed to
determine the targeted virtual host early in the TLS handshake, it was not
possible to switch the TLS protocol version of the connection at this point,
and thus the SSLProtocol negotiated was always based off
the one of the base virtual host (first virtual host declared on the
listening IP:port of the connection).

    

    
Beginning with Apache HTTP server version 2.4.42, when built/linked against
OpenSSL 1.1.1 or later, and when the SNI is provided by the client in the TLS
handshake, the SSLProtocol of each (name-based) virtual
host can and will be honored.

    

    
For compatibility with previous versions, if no
SSLProtocol is configured in a name-based virtual host,
the one from the base virtual host still applies, unless
SSLProtocol is configured globally in which case the
global value applies (this latter exception is more sensible than compatible,
though).

This directive sets the all-in-one file where you can assemble the
Certificates of Certification Authorities (CA) whose remote servers you deal
with. These are used for Remote Server Authentication. Such a file is simply the
concatenation of the various PEM-encoded Certificate files, in order of

This directive sets the directory where you keep the Certificates of
Certification Authorities (CAs) whose remote servers you deal with. These are used to
verify the remote server certificate on Remote Server Authentication.
    

    
The files in this directory have to be PEM-encoded and are accessed through
hash filenames. So usually you can't just place the Certificate files
there: you also have to create symbolic links named
hash-value.N. And you should always make sure this directory
contains the appropriate symbolic links.

Enables certificate revocation list (CRL) checking for the
remote servers you deal with. At least one of
SSLProxyCARevocationFile
or SSLProxyCARevocationPath must be
configured. When set to chain (recommended setting),
CRL checks are applied to all certificates in the chain, while setting it to
leaf limits the checks to the end-entity cert.

    

    

    When set to chain or leaf,
CRLs must be available for successful validation
    

    
Prior to version 2.3.15, CRL checking in mod_ssl also succeeded when
no CRL(s) were found in any of the locations configured with
SSLProxyCARevocationFile
or SSLProxyCARevocationPath.
With the introduction of this directive, the behavior has been changed:
when checking is enabled, CRLs must be present for the validation
to succeed - otherwise it will fail with an
"unable to get certificate CRL" error.

    Module:mod_ssl
    

    Compatibility:The proxy section context is allowed in httpd 2.4.30 and later
    

    

    
This directive sets whether the remote server certificate's CN field is
compared against the hostname of the request URL. If both are not equal
a 502 status code (Bad Gateway) is sent. SSLProxyCheckPeerCN is
superseded by SSLProxyCheckPeerName
in release 2.4.5 and later. 

    

    
In all releases 2.4.5 through 2.4.20, setting
SSLProxyCheckPeerName off was sufficient to enable this behavior
(as the SSLProxyCheckPeerCN default was on.) In 
these releases, both directives must be set to off to completely
avoid remote server certificate name validation. Many users reported this
to be very confusing.

    

    
As of release 2.4.21, all configurations which enable either one of the
SSLProxyCheckPeerName or SSLProxyCheckPeerCN options
will use the new SSLProxyCheckPeerName
behavior, and all configurations which disable either one of the 
SSLProxyCheckPeerName or SSLProxyCheckPeerCN options
will suppress all remote server certificate name validation. Only the following
configuration will trigger the legacy certificate CN comparison in 2.4.21 and
later releases;

    Compatibility:Apache HTTP Server 2.4.5 and later
    
The proxy section context is allowed in httpd 2.4.30 and later
    

    

    
This directive configures host name checking for server certificates when 
mod_ssl is acting as an SSL client. The check will succeed if the host name 
from the request URI matches one of the CN attribute(s) of the certificate's 
subject, or matches the subjectAltName extension. If the check fails, the SSL 
request is aborted and a 502 status code (Bad Gateway) is returned.

    

    
Wildcard matching is supported for specific cases: an subjectAltName entry
of type dNSName, or CN attributes starting with *. will match
with any host name of the same number of name elements and the same suffix.
E.g. *.example.org will match foo.example.org,
but will not match foo.bar.example.org, because the number of
elements in the respective host names differs.

    

    
This feature was introduced in 2.4.5 and superseded the behavior of the 
SSLProxyCheckPeerCN directive, which 
only tested the exact value in the first CN attribute against the host name.
However, many users were confused by the behavior of using these directives
individually, so the mutual behavior of SSLProxyCheckPeerName 
and SSLProxyCheckPeerCN directives were improved in release 
2.4.21. See the SSLProxyCheckPeerCN 
directive description for the original behavior and details of these 
improvements.

This directive toggles the usage of the SSL/TLS Protocol Engine for proxy. This
is usually used inside a <VirtualHost> section to enable SSL/TLS for proxy
usage in a particular virtual host. By default the SSL/TLS Protocol Engine is
disabled for proxy both for the main server and all configured virtual hosts.
    


    Note that the SSLProxyEngine directive should not, in
general, be included in a virtual host that will be acting as a
forward proxy (using <Proxy>
or ProxyRequests directives).
SSLProxyEngine is not required to enable a forward proxy
server to proxy SSL/TLS requests.

This directive sets the all-in-one file where you keep the certificates and
keys used for authentication of the proxy server to remote servers.

    

    
This referenced file is simply the concatenation of the various
PEM-encoded certificate files. Use this directive alternatively or
additionally to SSLProxyMachineCertificatePath.  The
referenced file can contain any number of pairs of client certificate
and associated private key.  Each pair can be specified in either
(certificate, key) or (key, certificate) order.  If the file includes
any non-leaf certificate, or any unmatched key and certificate pair, a
configuration error will be issued at startup.

    


    When challenged to provide a client certificate by a remote server,
the server should provide a list of acceptable certificate
authority names in the challenge.  If such a list is not
provided, mod_ssl will use the first configured
client cert/key.  If a list of CA names is provided,
mod_ssl will iterate through that list, and attempt
to find a configured client cert which was issued either directly by
that CA, or indirectly via any number of intermediary CA certificates.
The chain of intermediate CA certificates can be built from those
configured with SSLProxyMachineCertificateChainFile.  The
first configured matching certificate will then be supplied in
response to the challenge.
    


    If the list of CA names is provided by the remote server,
and no matching client certificate can be found, no client
certificate will be provided by mod_ssl, which will
likely fail the SSL/TLS handshake (depending on the remote server
configuration).

    When a proxy is configured to forward requests to a remote SSL
server, this directive can be used to configure certificate
verification of the remote server. 
    

    
The following levels are available for level:
    

      

    • none:
     no remote server Certificate is required at all
      • 

    • optional:
     the remote server may present a valid Certificate
      • 

    • require:
     the remote server has to present a valid Certificate
      • 

    • optional_no_ca:
     the remote server may present a valid Certificate
      
     but it need not to be (successfully) verifiable.
      • 

    

    In practice only levels none and
require are really interesting, because level
optional doesn't work with all servers and level
optional_no_ca is actually against the idea of
authentication (but can be used to establish SSL test pages, etc.)

This directive sets how deeply mod_ssl should verify before deciding that the
remote server does not have a valid certificate. 
    

    
The depth actually is the maximum number of intermediate certificate issuers,
i.e. the number of CA certificates which are max allowed to be followed while
verifying the remote server certificate. A depth of 0 means that self-signed
remote server certificates are accepted only, the default depth of 1 means
the remote server certificate can be self-signed or has to be signed by a CA
which is directly known to the server (i.e. the CA's certificate is under
SSLProxyCACertificatePath), etc.

[bytes]
    

    Context:server config
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This configures one or more sources for seeding the Pseudo Random Number
Generator (PRNG) in OpenSSL at startup time (context is
startup) and/or just before a new SSL connection is established
(context is connect). This directive can only be used
in the global server context because the PRNG is a global facility.
    

    
The following source variants are available:
    

      

    • builtin
    
       This is the always available builtin seeding source. Its usage
    consumes minimum CPU cycles under runtime and hence can be always used
    without drawbacks. The source used for seeding the PRNG contains of the
    current time, the current process id and a randomly
    chosen 128 bytes extract of the stack.
    The drawback is that this is not really a strong source and at startup
    time (where the scoreboard is still not available) this source just
    produces a few bytes of entropy. So you should always, at least for the
    startup, use an additional seeding source.
      • 

    • file:/path/to/source
    
      
    This variant uses an external file /path/to/source as the
    source for seeding the PRNG. When bytes is specified, only the
    first bytes number of bytes of the file form the entropy (and
    bytes is given to /path/to/source as the first
    argument). When bytes is not specified the whole file forms the
    entropy (and 0 is given to /path/to/source as
    the first argument). Use this especially at startup time, for instance
    with an available /dev/random and/or
    /dev/urandom devices (which usually exist on modern Unix
    derivatives like FreeBSD and Linux).
      
    
      
    But be careful: Usually /dev/random provides only as
    much entropy data as it actually has, i.e. when you request 512 bytes of
    entropy, but the device currently has only 100 bytes available two things
    can happen: On some platforms you receive only the 100 bytes while on
    other platforms the read blocks until enough bytes are available (which
    can take a long time). Here using an existing /dev/urandom is
    better, because it never blocks and actually gives the amount of requested
    data. The drawback is just that the quality of the received data may not
    be the best.
      • 


    • exec:/path/to/program
    
      
    This variant uses an external executable
    /path/to/program as the source for seeding the
    PRNG. When bytes is specified, only the first
    bytes number of bytes of its stdout contents
    form the entropy. When bytes is not specified, the
    entirety of the data produced on stdout form the
    entropy. Use this only at startup time when you need a very strong
    seeding with the help of an external program (for instance as in
    the example above with the truerand utility you can
    find in the mod_ssl distribution which is based on the AT&T
    truerand library). Using this in the connection context
    slows down the server too dramatically, of course.  So usually you
    should avoid using external programs in that context.
      • 

    • egd:/path/to/egd-socket (Unix only)
    
      
    This variant uses the Unix domain socket of the
    external Entropy Gathering Daemon (EGD) (see http://www.lothar.com/tech
    /crypto/) to seed the PRNG. Use this if no random device exists
    on your platform.
      •

    SSLRandomSeed startup builtin
SSLRandomSeed startup "file:/dev/random"
SSLRandomSeed startup "file:/dev/urandom" 1024

    If an SSL renegotiation is required in per-location context, for
example, any use of SSLVerifyClient in a Directory or
Location block, then mod_ssl must buffer any HTTP
request body into memory until the new SSL handshake can be performed.
This directive can be used to set the amount of memory that will be
used for this buffer. 
    


    
Note that in many configurations, the client sending the request body
will be untrusted so a denial of service attack by consumption of
memory must be considered when changing this configuration setting.

    SSLRequire is deprecated
    

    SSLRequire is deprecated and should in general be replaced
by Require expr. The so called
ap_expr syntax of Require expr is
a superset of the syntax of SSLRequire, with the following
exception:
    


    In SSLRequire, the comparison operators <,
<=, ... are completely equivalent to the operators
lt, le, ... and work in a somewhat peculiar way that
first compares the length of two strings and then the lexical order.
On the other hand, ap_expr has two sets of
comparison operators: The operators <,
<=, ... do lexical string comparison, while the operators
-lt, -le, ... do integer comparison.
For the latter, there are also aliases without the leading dashes:
lt, le, ...

    


    


    
This directive specifies a general access requirement which has to be
fulfilled in order to allow access. It is a very powerful directive because the
requirement specification is an arbitrarily complex boolean expression
containing any number of access checks.
    

    
The expression must match the following syntax (given as a BNF
grammar notation):
    

    

    expr     ::= "true" | "false"
           | "!" expr
           | expr "&&" expr
           | expr "||" expr
           | "(" expr ")"
           | comp

comp     ::= word "==" word | word "eq" word
           | word "!=" word | word "ne" word
           | word "<"  word | word "lt" word
           | word "<=" word | word "le" word
           | word ">"  word | word "gt" word
           | word ">=" word | word "ge" word
           | word "in" "{" wordlist "}"
           | word "in" "PeerExtList(" word ")"
           | word "=~" regex
           | word "!~" regex

wordlist ::= word
           | wordlist "," word

word     ::= digit
           | cstring
           | variable
           | function

digit    ::= [0-9]+
cstring  ::= "..."
variable ::= "%{" varname "}"
function ::= funcname "(" funcargs ")"
    

    

    For varname any of the variables described in Environment Variables can be used.  For
funcname the available functions are listed in
the ap_expr documentation.
    


    The expression is parsed into an internal machine
representation when the configuration is loaded, and then evaluated
during request processing.  In .htaccess context, the expression is
both parsed and executed each time the .htaccess file is encountered during
request processing.
    


    Example
    SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)-/                   \
            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd."          \
            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"}    \
            and %{TIME_WDAY} -ge 1 and %{TIME_WDAY} -le 5          \
            and %{TIME_HOUR} -ge 8 and %{TIME_HOUR} -le 20       ) \
           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
    

    


    The PeerExtList(object-ID) function expects
to find zero or more instances of the X.509 certificate extension
identified by the given object ID (OID) in the client certificate.
The expression evaluates to true if the left-hand side string matches
exactly against the value of an extension identified with this OID.
(If multiple extensions with the same OID are present, at least one
extension must match).
    


    Example
    SSLRequire "foobar" in PeerExtList("1.2.3.4.5.6")
    

    


    Notes on the PeerExtList function
    


      


    • The object ID can be specified either as a descriptive
name recognized by the SSL library, such as "nsComment",
or as a numeric OID, such as "1.2.3.4.5.6".
      • 


    • Expressions with types known to the SSL library are rendered to
a string before comparison.  For an extension with a type not
recognized by the SSL library, mod_ssl will parse the value if it is
one of the primitive ASN.1 types UTF8String, IA5String, VisibleString,
or BMPString.  For an extension of one of these types, the string
value will be converted to UTF-8 if necessary, then compared against
the left-hand-side expression.

This directive forbids access unless HTTP over SSL (i.e. HTTPS) is enabled for
the current connection. This is very handy inside the SSL-enabled virtual
host or directories for defending against configuration errors that expose
stuff that should be protected. When this directive is present all requests
are denied which are not using SSL.

Cache
    

    Syntax:SSLSessionCache type
    

    Default:SSLSessionCache none
    

    Context:server config
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This configures the storage type of the global/inter-process SSL Session
Cache. This cache is an optional facility which speeds up parallel request
processing. For requests to the same server process (via HTTP keep-alive),
OpenSSL already caches the SSL session information locally. But because modern
clients request inlined images and other data via parallel requests (usually
up to four parallel requests are common) those requests are served by
different pre-forked server processes. Here an inter-process cache
helps to avoid unnecessary session handshakes.
    

    
The following five storage types are currently supported:
    

      

    • none

    
      This disables the global/inter-process Session Cache.  This
    will incur a noticeable speed penalty and may cause problems if
    using certain browsers, particularly if client certificates are
    enabled.  This setting is not recommended.
      • 


    • nonenotnull

    
      This disables any global/inter-process Session Cache.  However
    it does force OpenSSL to send a non-null session ID to
    accommodate buggy clients that require one.
      • 


    • dbm:/path/to/datafile

    
      This makes use of a DBM hashfile on the local disk to
    synchronize the local OpenSSL memory caches of the server
    processes. This session cache may suffer reliability issues under
    high load. To use this, ensure that
    mod_socache_dbm is loaded.
      • 


    • shmcb:/path/to/datafile[(size)]

    
      This makes use of a high-performance cyclic buffer
    (approx. size bytes in size) inside a shared memory
    segment in RAM (established via /path/to/datafile) to
    synchronize the local OpenSSL memory caches of the server
    processes.  This is the recommended session cache. To use this,
    ensure that mod_socache_shmcb is loaded.
      • 


    • dc:UNIX:/path/to/socket

    
      This makes use of the distcache distributed session
    caching libraries.  The argument should specify the location of
    the server or proxy to be used using the distcache address syntax;
    for example, UNIX:/path/to/socket specifies a UNIX
    domain socket (typically a local dc_client proxy);
    IP:server.example.com:9001 specifies an IP
    address. To use this, ensure that
    mod_socache_dc is loaded.
      • 


    


    Examples
    SSLSessionCache "dbm:/usr/local/apache/logs/ssl_gcache_data"
SSLSessionCache "shmcb:/usr/local/apache/logs/ssl_gcache_data(512000)"
    

    


    The ssl-cache mutex is used to serialize access to
the session cache to prevent corruption.  This mutex can be configured
using the Mutex directive.

This directive sets the timeout in seconds for the information stored in the
global/inter-process SSL Session Cache, the OpenSSL internal memory cache and
for sessions resumed by TLS session resumption (RFC 5077).

    Compatibility:Available in httpd 2.4.0 and later, if using OpenSSL 0.9.8h or later
    

    

    Optionally configures a secret key for encrypting and decrypting
TLS session tickets, as defined in
RFC 5077.
Primarily suitable for clustered environments where TLS sessions information
should be shared between multiple nodes. For single-instance httpd setups,
it is recommended to not configure a ticket key file, but to
rely on (random) keys generated by mod_ssl at startup, instead.
    

    The ticket key file must contain 48 bytes of random data,
preferably created from a high-entropy source. On a Unix-based system,
a ticket key file can be created as follows:
    


    
dd if=/dev/random of=/path/to/file.tkey bs=1 count=48

    


    Ticket keys should be rotated (replaced) on a frequent basis,
as this is the only way to invalidate an existing session ticket -
OpenSSL currently doesn't allow to specify a limit for ticket lifetimes.
A new ticket key only gets used after restarting the web server.
All existing session tickets become invalid after a restart.
    


    

    The ticket key file contains sensitive keying material and should
be protected with file permissions similar to those used for
SSLCertificateKeyFile.

    This option enables OCSP stapling, as defined by the "Certificate
Status Request" TLS extension specified in RFC 6066. If enabled (and
requested by the client), mod_ssl will include an OCSP response
for its own certificate in the TLS handshake. Configuring an
SSLStaplingCache is a
prerequisite for enabling OCSP stapling.
    


    OCSP stapling relieves the client of querying the OCSP responder
on its own, but it should be noted that with the RFC 6066 specification,
the server's CertificateStatus reply may only include an
OCSP response for a single cert. For server certificates with intermediate
CA certificates in their chain (the typical case nowadays),
stapling in its current implementation therefore only partially achieves the
stated goal of "saving roundtrips and resources" - see also
RFC 6961
(TLS Multiple Certificate Status Extension).

    


    When OCSP stapling is enabled, the ssl-stapling mutex is used
to control access to the OCSP stapling cache in order to prevent corruption,
and the sss-stapling-refresh mutex is used to control refreshes
of OCSP responses.  These mutexes can be configured using the
Mutex directive.

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive sets the Certificate verification level for the Client
Authentication. Notice that this directive can be used both in per-server and
per-directory context. In per-server context it applies to the client
authentication process used in the standard SSL handshake when a connection is
established. In per-directory context it forces a SSL renegotiation with the
reconfigured client verification level after the HTTP request was read but
before the HTTP response is sent.
    

    
The following levels are available for level:
    

      

    • none:
     no client Certificate is required at all
      • 

    • optional:
     the client may present a valid Certificate
      • 

    • require:
     the client has to present a valid Certificate
      • 

    • optional_no_ca:
     the client may present a valid Certificate
      
     but it need not to be (successfully) verifiable. This option
     cannot be relied upon for client authentication.  
      • 

    

    Example
    SSLVerifyClient require

    SSLVerifyDepth Directive
    

    

    Description:Maximum depth of CA Certificates in Client
Certificate verification
    

    Syntax:SSLVerifyDepth number
    

    Default:SSLVerifyDepth 1
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_ssl
    

    

    
This directive sets how deeply mod_ssl should verify before deciding that the
clients don't have a valid certificate. Notice that this directive can be
used both in per-server and per-directory context. In per-server context it
applies to the client authentication process used in the standard SSL
handshake when a connection is established. In per-directory context it forces
a SSL renegotiation with the reconfigured client verification depth after the
HTTP request was read but before the HTTP response is sent.
    

    
The depth actually is the maximum number of intermediate certificate issuers,
i.e. the number of CA certificates which are max allowed to be followed while
verifying the client certificate. A depth of 0 means that self-signed client
certificates are accepted only, the default depth of 1 means the client
certificate can be self-signed or has to be signed by a CA which is directly
known to the server (i.e. the CA's certificate is under
SSLCACertificatePath), etc.
    

    Example
    SSLVerifyDepth 10

    Serveur HTTP Apache Version 2.4

    Module Apache mod_proxy_ftp
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Module fournissant le support FTP à
mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_ftp_module
    

    Fichier Source:mod_proxy_ftp.c
    

    Sommaire
    

    
    Pour pouvoir fonctionner, ce module requiert le
    chargement de mod_proxy. Il fournit le support du
    mandatement des sites FTP. Notez que le support FTP est
    actuellement limité à la méthode GET.
    

    
    Ainsi, pour pouvoir traiter les requêtes FTP mandatées,
    mod_proxy, et mod_proxy_ftp
    doivent être chargés dans le serveur.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large.
    
    
    

    


    top
    

    

    Pourquoi les fichiers du type
    xxx ne sont-ils pas téléchargeables par FTP ?
    
      
    Ce type particulier de fichier n'est probablement pas défini en
      temps que application/octet-stream dans le fichier
      de configuration mime.types de votre mandataire. La ligne suivante
      peut y remédier :
    

      
    application/octet-stream   bin dms lha lzh exe class tgz taz
    
    
    Vous pouvez aussi utiliser la directive ForceType pour définir par défaut tous les types
    de fichiers en tant que fichiers binaires :
    
      
    ForceType application/octet-stream
    

    
    
    top
    

    

    Comment puis-je forcer le téléchargement
    FTP en mode ASCII du fichier xxx ?
    
      
    Dans les rares siruations où vous devez télécharger un fichier
      spécifique en utilisant la méthode de transfert FTP
      ASCII (alors que le mode transfert par défaut est
      binary), vous pouvez modifier le mode de transfert de
      mod_proxy en suffixant la requête avec
      ;type=a pour forcer un transfert en mode ASCII (les
      listings de répertoires FTP sont cependant quant à eux transmis en
      mode ASCII).
    
    
    top
    

    

    Comment puis-je effectuer un
    chargement FTP ?
    
    
    Actuellement, seule la méthode GET est supportée pour FTP dans
    mod_proxy. Vous pouvez par contre utiliser le chargement HTTP (POST
    or PUT) via un mandataire Apache.
    
    
    top
    

    

    Comment puis-je accéder par FTP à
    des fichiers situés en dehors de mon répertoire home ?
    
      
    Un URI FTP est considéré comme relatif au répertoire home de
      l'utilisateur connecté. Hélas, vous ne pouvez pas utiliser /../
      pour atteindre des répertoires de niveau supérieur, car les points
      sont interprétés par le navigateur et ne sont donc pas vraiment
      envoyés au serveur FTP. Pour traiter ce problème, une méthode
      nommée Squid %2f hack a été implémentée dans le
      mandataire FTP Apache ; cette solution est aussi utilisée par
      d'autres serveurs mandataires courants comme le Cache mandataire Squid. En
      préfixant par /%2f le chemin de votre requête, vous
      pouvez faire en sorte que le mandataire modifie le répertoire FTP
      racine en / (au lieu du répertoire home). Par
      exemple, pour extraire le fichier /etc/motd, vous
      pourriez utiliser l'URL :
    

      
    
        ftp://utilisateur@serveur/%2f/etc/motd
      
    
    
    top
    

    

    Comment puis-je dissimuler le mot de
    passe FTP apparaissant en clair dans la ligne d'URL de mon
    navigateur ?
    
      
    Apache utilise différentes stratégies pour effectuer une
      connexion à un serveur FTP à l'aide d'un nom d'utilisateur et d'un
      mot de passe. En l'absence de nom d'utilisateur et de mot de passe
      dans l'URL, Apache tente une connexion anonyme auprès du serveur
      FTP comme suit :
    

      
    
        utilisateur : anonymous
    
        mot de passe : apache-proxy@
      
    

      
    Ceci fonctionne avec tous les serveurs FTP courants configurés
      pour accepter les connexions anonymes.
    

      
    Pour une connexion personnalisée avec un nom d'utilisateur
      spécifique, vous pouvez intégrer ce dernier dans l'URL comme suit
      :
    

      
    
        ftp://nom-utilisateur@serveur/mon-fichier
      
    

      
    Si le serveur FTP demande un mot de passe pour ce nom
      d'utilisateur (ce qu'il est censé faire), Apache va renvoyer au
      client une réponse 401 (Autorisation requise), ce qui
      fera afficher au navigateur une boîte de dialogue utilisateur/mot
      de passe. Une fois le mot de passe saisi, la connexion est tentée
      à nouveau, et si elle réussit, la ressource demandée est
      présentée. L'avantage de cette procédure réside dans le fait que
      votre navigateur n'affiche pas le mot de passe en clair, ce qu'il
      aurait fait si vous aviez utilisé l'URL :
    

      
    
        ftp://nom-utilisateur:mot-de-passe@serveur/mon-fichier
      
    

      
    Note
    
        
    Le mot de passe transmis de cette manière n'est pas chiffré
	lorsqu'il est envoyé. Il transite entre votre navigateur et le
	serveur mandataire Apache sous la forme d'une chaîne de texte en
	clair codée en base64, et entre le mandataire Apache et le
	serveur FTP en texte pur. Vous devez par conséquent réfléchir à
	deux fois avant d'accéder à votre serveur FTP via HTTP (et d'une
	manière générale avant d'accéder à vos fichiers personnels via
	FTP !) sur des canaux non sécurisés, car des oreilles
	indiscrètes pourraient intercepter votre mot de passe au cours
	de son transfert.

    Pourquoi reçois-je un listing de
    fichiers alors que j'ai demandé le téléchargement d'un fichier
    ?
    
      
    Apache examine l'URL de la requête afin de permettre la
      navigation dans les répertoires d'un serveur FTP ainsi que le
      téléchargement de fichiers. Si elle ressemble à un répertoire, ou
      contient des caractères génériques ("*?[{~"), alors Apache
      considère que c'est un listing qui est demandé, et non un
      téléchargement.
    
      
    Vous pouvez désactiver le traitement spécial des noms contenant
      des caractères génériques. Voir à cet effet la directive
      ProxyFtpListOnWildcard.

    Compatibilité:Disponible depuis la version 2.3.3 du serveur HTTP Apache
    

    
  
    La directive ProxyFtpEscapeWildcards permet
  de déterminer si les caractères génériques ("*?[{~") que contiennent
  les noms de fichiers demandés doivent être échappés pas un slash
  inversé avant d'être envoyés au serveur FTP. Il s'agit du comportement
  par défaut ; cependant, de nombreux serveurs FTP n'ont aucune
  connaissance de la notion d'échappement, et tentent de servir le
  fichier demandé sous sa forme littérale, en incluant les slashes
  inversés dans son nom.
    
    
    Définissez cette directive à "off" pour permettre le
    téléchargement de fichiers dont les noms contiennent des caractères
    génériques depuis des serveurs FTP qui ne connaissent pas
    l'échappement des caractères génériques.

  les noms de fichiers demandés provoquent l'affichage d'un listing de
  fichiers par mod_proxy_ftp au lieu de télécharger un
  fichier. Il s'agit de leur comportement par défaut (valeur on).
    
  
    Définissez cette directive à "off" pour permettre le téléchargement de
  fichiers même si leur nom contient des caractères génériques.

    Description:Associe les extensions des fichiers demandés avec l'action
déclenchée par ces fichiers et avec leur contenu (type MIME, langue,
jeu de caractère et codage)
    

    Statut:Base
    

    Identificateur de Module:mime_module
    

    Fichier Source:mod_mime.c
    

    Sommaire
    

    
    Ce module permet d'assigner des métadonnées aux contenus
    sélectionnés pour une réponse HTTP, en associant des modèles d'URI
    ou de noms de fichiers aux valeurs des métadonnées. Par exemple, les
    extensions de noms de fichiers définissent souvent le type de médium
    Internet, la langue, le jeu de caractères et le codage du contenu.
    Ces informations sont relayées par les messages HTTP véhiculant ces
    contenus, et utilisées au cours de la négociation de contenu lors de
    la sélection des différentes possibilités, de manière à ce que les
    préférences des utilisateurs soient respectées lors du choix d'un
    contenu à servir parmi plusieurs autres contenus. Voir
    mod_negotiation pour plus d'informations à propos
    de la négociation de
    contenu.
    

    
    Les directives AddCharset, AddEncoding, AddLanguage et AddType permettent d'associer des
    extensions de fichiers aux métadonnées de ces fichiers. Elles
    définissent respectivement le jeu de caractères, le codage du
    contenu, la langue du contenu et le type de
    médium (content-type) des documents. La directive
    TypesConfig permet de
    spécifier un fichier qui contient lui-même des associations entre
    extensions et types de media.
    

    
    De plus, mod_mime peut définir le gestionnaire et les filtres qui sont à l'origine du contenu et
    le traitent. Les directives AddHandler, AddOutputFilter, et AddInputFilter permettent de contrôler
    les modules ou les scripts qui vont servir le document. La directive
    MultiviewsMatch permet à
    mod_negotiation de déterminer les extensions de
    fichiers à inclure lors des tests de correspondances multivues.
    

    
    Alors que mod_mime associe des métadonnées avec
    des extensions de fichiers, le serveur de base core
    fournit des directives permettant d'associer tous les fichiers d'un
    conteneur donné (par exemple <Location>, <Directory>, ou <Files>) avec des métadonnées particulières.
    Parmi ces directives, on trouve ForceType, SetHandler, SetInputFilter, et SetOutputFilter. Les directives du serveur
    de base l'emportent sur toute directive d'association d'extensions
    de noms de fichiers définie par mod_mime.
    

    
    Notez que la modification des métadonnées d'un fichier ne modifie
    pas la valeur de l'en-tête Last-Modified. Ainsi,
    certaines copies de documents préalablement mises en cache peuvent
    encore être utilisées par un client ou un mandataire avec les
    anciens en-têtes. Si vous modifiez les métadonnées (langue, type de
    contenu, jeu de caractère ou codage), vous devez donc enregistrer
    une modification du fichier concerné (afin de mettre à jour sa date
    de dernière modification), pour être sûr que tous les visiteurs
    recevront le documents avec les en-têtes corrects. 
    

    


    top
    

    

    Fichiers avec extensions
multiples
    
    
    Les fichiers peuvent posséder plusieurs extensions dont l'ordre
    est normalement sans importance. Par exemple, si
    le fichier welcome.html.fr est associé au type de
    contenu text/html et à la langue française, le fichier
    welcome.fr.html possèdera exactement les même
    métadonnées. Si le fichier possède plusieurs extensions associées
    au même type de métadonnée, c'est celle de ces extensions la plus à
    droite qui sera utilisée, excepté pour ce qui concerne les langues
    et les codages de contenu. Par exemple, si .gif est
    associé au type de médium
    image/gif, et .html au type de médium
    text/html, le fichier welcome.gif.html
    sera associé au type de médium text/html.
    

    
    Les Languages et les codages de contenu sont traités de
    manière cumulative, car il est possible d'assigner plusieurs
    langues ou codages à une ressource particulière. Par exemple, le
    fichier welcome.html.en.de sera servi avec les en-têtes
    Content-Language: en, de et Content-Type:
    text/html.
    

    
    Des précautions doivent être prises lorsqu'un fichier avec
    extensions multiples est associé à la fois à un type de
    médium et à un gestionnaire. En général, cela impliquera
    la gestion de la requête par le module associé au gestionnaire. Par
    exemple, si l'extension .imap est associée au
    gestionnaire imap-file (du module
    mod_imagemap), et si l'extension .html
    est associée au type de médium text/html, le fichier
    world.imap.html sera à la fois associé au gestionnaire
    imap-file et au type de médium text/html.
    Pour son traitement, c'est le gestionnaire imap-file
    qui sera utilisé, et il sera donc traité en tant que fichier
    imagemap.
    

    
    Si vous préférez que seule la dernière partie d'un nom de fichier
    séparée du reste du nom par un point soit associée à une métadonnée
    particulière, n'utilisez pas les directives Add*. Par
    exemple, si vous souhaitez que le fichier foo.html.cgi
    soit traité en tant que script CGI, mais pas le fichier
    bar.cgi.html, alors, au lieu d'utiliser
    AddHandler cgi-script .cgi, utilisez plutôt :
    

    
    Configuration du gestionnaire en se basant seulement
    sur la dernière extension
    <FilesMatch "[^.]+\.cgi$">
  SetHandler cgi-script
</FilesMatch>
    

    


    top
    

    

    Codage du contenu
    
    
    Un fichier d'un type de médium particulier
    peut être également codé d'une certaine manière pour simplifier sa
    transmission sur Internet. Alors que cela concerne en général la
    compression, comme gzip, il peut aussi s'agir de
    chiffrement, comme pgp ou d'un codage comme UUencoding,
    qui est conçu pour transmettre un fichier binaire sous un format
    ASCII (texte).
    

    
    La RFC
    HTTP/1.1, section 14.11 stipule à ce titre :
    

    
    
      
    Le champ d'en-tête Content-Encoding de l'entité est utilisé en
      tant que modificateur du type de médium. Lorsqu'il est présent, sa
      valeur indique quels codages de contenu additionnels ont été
      appliqués au corps de l'entité, et ainsi quels mécanismes de
      décodage doivent être appliqués afin de retrouver le type de
      médium référencé par le champ d'en-tête Content-Type. Le codage de
      contenu est principalement utilisé pour permettre la compression
      d'un document sans perdre l'information concernant le type de
      médium sous-jacent.
    
    
    

    
    En utilisant plusieurs extensions (voir la section ci-dessus à propos des extensions de
    fichiers multiples), vous pouvez indiquer qu'un fichier est d'un
    type, particulier, et possède aussi un codage
    particulier.
    

    
    Considérons par exemple un fichier contenant un document
    Microsoft Word et compressé par pkzip pour réduire sa taille. Si
    l'extension .doc est associée au type de fichier
    Microsoft Word, et si l'extension .zip est associée au
    codage de fichier pkzip, alors le fichier
    Resume.doc.zip sera identifié comme document Word
    compressé par pkzip.
    

    
    Apache joint un en-tête Content-encoding à la
    ressource afin d'informer le navigateur client à propos de la
    méthode de codage.
    

    
    Content-encoding: pkzip
    


    top
    

    

    Jeux de caractères et langues
    
    
    En plus du type de fichier et du codage, un autre élément
    important d'information est la langue dans laquelle le document est
    écrit, et avec quel jeu de caractères le contenu du fichier doit
    être affiché. Par exemple, un document peut être écrit en alphabet
    vietnamien ou cyrillique, et doit être affiché en conséquence. Cette
    information est également transmise via des en-têtes HTTP.
    

    
    Les jeu de caractères, langue, codage et type MIME sont tous
    utilisés au cours du processus de négociation de contenu (voir
    mod_negotiation) afin de déterminer quel document
    servir au client, lorsque plusieurs choix sont possibles en fonction
    du jeu de caractères, de la langue, du codage ou du type MIME. Toutes
    les associations d'extensions de noms de fichiers créées via les
    directives AddCharset,
    AddEncoding, AddLanguage et AddType (ainsi que les associations
    d'extensions listées dans le fichier défini par la directive
    MimeMagicFile),
    participent à ce processus de sélection. Les extensions de noms de
    fichiers qui n'ont été associés que par des directives AddHandler, AddInputFilter ou AddOutputFilter, peuvent être incluses
    ou exclues du processus de sélection en utilisant la directive
    MultiviewsMatch.
    

    
    Jeu de caractères
    
      
    Pour transmettre cette information supplémentaire, Apache peut
      ajouter un en-tête Content-Language, afin de
      spécifier la langue dans laquelle le document est écrit, et peut
      ajouter des informations additionnelles à l'en-tête
      Content-Type pour indiquer le jeu de caractères
      particulier qui doit être utilisé pour restituer correctement le
      document.
    

      
    
        Content-Language: en, fr
Content-Type: text/plain; charset=ISO-8859-1
      
    

      
    La langue est spécifiée via son abréviation en deux lettres. Le
      jeu de caractères est le nom du jeu de caractères
      particulier qui doit être utilisé.

    Surcharges autorisées:FileInfo
    

    Statut:Base
    

    Module:mod_mime
    

    
    
    La directive AddCharset permet d'associer
    les extensions de noms de fichiers spécifiées au jeu de caractères
    spécifié (le nom enregistré sur l'Internet d'un codage de caractères
    donné). jeu-car est le paramètre jeu
    de caractères du type de médium pour les ressources dont le nom
    de fichier contient extension. Cette association est
    ajoutée à toutes les autres déjà en vigueur, et écrase toute
    association préexistante pour la même extension.
    

    
    Exemple
    AddLanguage ja .ja
AddCharset EUC-JP .euc
AddCharset ISO-2022-JP .jis
AddCharset SHIFT_JIS .sjis
    

    

    
    Avec cet exemple, le document xxxx.ja.jis sera
    traité en tant que document japonais dont le jeu de caractère est
    ISO-2022-JP (idem pour le document
    xxxx.jis.ja). La directive
    AddCharset sert à la fois à informer le
    client sur le codage des caractères du document afin que ce dernier
    puisse être interprété et affiché correctement, et à la négociation de contenu, au
    cours de laquelle le serveur décide lequel parmi plusieurs
    documents possibles il renvoie au client en fonction des préférences
    de ce dernier en matière de jeu de caractères.
    

    
    L'argument extension est insensible à la casse et peut
    être spécifié avec ou sans le point initial. Les noms de fichiers
    peuvent posséder plusieurs extensions, et
    l'argument extension sera comparé à chacune d'entre
    elles.

    Module:mod_mime
    

    
    
    La directive AddEncoding permet d'associer
    les extensions de noms de fichiers données au codage de contenu HTTP
    spécifié. codage est le codage de contenu HTTP à ajouter
    à la valeur du champ d'en-tête Content-Encoding pour les documents
    possédant l'extension spécifiée. Cette association est
    ajoutée à toutes les autres déjà en vigueur, et écrase toute
    association préexistante pour la même extension.
    

    
    Exemple
    AddEncoding x-gzip .gz
AddEncoding x-compress .Z
    

    

    
    Avec cet exemple, les noms de fichiers possédant l'extension
    .gz seront marqués comme codés à l'aide du codage
    x-gzip, et les noms de fichiers possédant l'extension
    .Z comme codés avec x-compress.
    

    
    Les clients anciens n'acceptent que x-gzip et
    x-compress, bien que les standards stipulent qu'ils
    sont respectivement équivalents à gzip et
    compress. Apache effectue ses comparaisons de codages
    de contenu en ignorant tout préfixe x-. Lorsqu'il
    répond avec un codage, Apache utilise l'une ou l'autre forme (c'est
    à dire x-foo ou foo) selon les besoins du
    client. Si le client n'a pas besoin d'une forme particulière, Apache
    utilisera la forme employée par la directive
    AddEncoding. Pour résumer, vous devez toujours utiliser
    x-gzip et x-compress pour ces deux
    codages spécifiques. Certains codages plus récents, comme
    deflate, doivent être spécifiés sans le préfixe
    x-.

    Module:mod_mime
    

    
    
    La directive AddLanguage permet d'associer
    l'extension de nom de fichier donnée à la langue spécifiée. Les
    fichiers dont l'extension correspond à la valeur
    de l'argument extension se voient attribuer la valeur de
    l'argument symbole-langue comme en-tête HTTP
    Content-Language en accord avec les identifiants de langues définis
    par la RFC 3066. Cette directive l'emporte sur toute association
    préexistante pour la même extension.
    

    
    Exemple
    AddEncoding x-compress .Z
AddLanguage en .en
AddLanguage fr .fr
    

    

    
    Avec cet exemple, le document xxxx.en.Z sera traité
    en tant que document compressé de langue anglaise (idem pour le
    document xxxx.Z.en). Bien que la langue soit fournie au
    client, le navigateur n'utilise habituellement pas cette
    information. La directive AddLanguage est
    principalement utilisée au cours de la négociation de contenu, où le
    serveur choisit d'envoyer un document parmi plusieurs documents
    possibles en fonction de la préférence du client en matière de
    langue.
    

    
    Si une extension fait l'objet de plusieurs associations de
    langues, c'est la dernière qui sera utilisée. Ainsi, dans le cas
    suivant,
    

    
    AddLanguage en .en
AddLanguage en-gb .en
AddLanguage en-us .en
    


    
    les documents possédant l'extension .en seront
    traités en tant que documents de langue en-us.

    La directive AddOutputFilter permet

    extension aux filtres qui traiteront les réponses en
    provenance du serveur avant de les envoyer au client. Ces filtres
    s'ajoutent à tout filtre défini par d'autres directives comme
    SetOutputFilter et AddOutputFilterByType. Cette association
    est fusionnée avec toute autre association en vigueur, et l'emporte
    sur toute association préexistante pour la même
    extension.

    sortie sera compressée à l'aide du module
    mod_deflate.
    

    
    AddOutputFilter INCLUDES;DEFLATE shtml

    Surcharges autorisées:FileInfo
    

    Statut:Base
    

    Module:mod_mime
    

    
    
    La directive AddType permet d'associer les
    extensions de noms de fichiers données au type de contenu spécifié.
    type-médium est le Type
    MIME à utiliser pour les fichiers dont le nom possède
    l'extension extension. Cette association s'ajoute à toute
    autre association en vigueur, et l'emporte sur toute association
    préexistante pour la même extension.
    

    
    
      Plutôt que d'éditer directement le fichier TypesConfig, il est recommandé
      d'utiliser la directive AddType pour
      ajouter de nouveaux types de médias.
    
    

    
    Exemple
    AddType image/gif .gif
    

    

    
    Ou, pour spécifier plusieurs extensions dans une seule directive
    :
    

    
    Exemple
    AddType image/jpeg jpeg jpg jpe
    

    

    
    L'argument extension est insensible à la casse et peut
    être spécifié avec ou sans le point initial. Les noms de fichiers
    peuvent posséder plusieurs extensions, et
    l'argument extension sera comparé à chacune d'entre
    elles.
    

    
    Il est possible d'obtenir un effet similaire à celui de la
    directive LanguagePriority du module
    mod_negotiation en qualifiant un type de
    média avec qs :
    

    
    Exemple
    AddType application/rss+xml;qs=0.8 .xml
    

    

    
    Ceci peut s'avérer utile dans certaines situations, par exemple
    lorsqu'un client qui a ajouté un en-tête Accept: */* à
    sa requête n'est pas en mesure de traiter le contenu renvoyé par le
    serveur.
    

    
    À la base, cette directive configure le type de contenu généré
    pour les fichiers statiques servis à partir du système de fichiers.
    Dans le cas des ressources autres que les fichiers statiques pour
    lesquelles le générateur de la réponse spécifie en général un
    Content-Type, cette directive n'a aucun effet.
    

    
    Note
    
    
    Si aucun gestionnaire n'est explicitement défini pour une
    requête, le type de contenu spécifié sera aussi utilisé comme nom du
    gestionnaire.
    

    
    Lorsqu'aucune directive comme SetHandler ou
    AddHandler ne s'applique à
    une requête, le nom de gestionnaire interne normalement défini
    par une de ces directives est en fait défini par le type de contenu
    spécifié par la présente directive.
    
    
    
    Pour des raisons historiques, certains modules tiers comme mod_php
    peuvent adopter ce type de comportement pour prendre en compte la
    requête concernée.
    
    
    
    Il est conseillé d'éviter les configurations qui reposent sur de
    tels types "synthétiques". En outre, les configurations qui
    limitent l'accès aux directives SetHandler ou AddHandler doivent aussi limiter
    l'accès à la directive AddType.

    <Directory>
    courant) qui ne possèdent pas d'extension de langue explicite
    (comme .fr ou .de tel que défini par la
    directive AddLanguage),
    verront leur en-tête HTTP Content-Language affecté de la langue
    symbole-langue. Ceci permet de marquer des arborescences
    de répertoires entières comme contenant des documents en français,
    par exemple, sans avoir à renommer chaque fichier. Notez qu'à la
    différence de l'utilisation des extensions pour spécifier des
    langues, DefaultLanguage ne permet de
    spécifier qu'une seule langue.
    

    
    Si aucune directive DefaultLanguage n'est
    en vigueur, et si un fichier ne possède pas d'extension configurée
    par la directive AddLanguage, aucun champ d'en-tête

    Considérons une requête pour /index.php/foo.shtml,
    mod_mime ne traitera pas la requête entrante comme
    /index.php/foo.shtml et les directives comme
    AddOutputFilter INCLUDES .shtml ajouteront le filtre
    INCLUDES à la requête. Si la directive
    ModMimeUsePathInfo n'est pas définie, le
    filtre INCLUDES ne sera pas ajouté. Le fonctionnement
    sera identique dans le cas des chemins virtuels, tels que ceux
    définis par la directive <Location>

    Surcharges autorisées:FileInfo
    

    Statut:Base
    

    Module:mod_mime
    

    
    
    La directive MultiviewsMatch permet trois
    comportements différents pour la fonctionnalité Multiviews du module
    mod_negotiation. Les vues
    multiples permettent d'associer une requête pour un fichier, par
    exemple index.html, à toute extension négociée
    s'ajoutant à la requête de base, par exemple
    index.html.en, index.html.fr, ou
    index.html.gz.
    

    
    L'option NegotiatedOnly implique que toute extension
    s'ajoutant au nom de base doit correspondre à une extension de
    mod_mime reconnue pour la négociation de contenu,
    par exemple Charset, Content-Type, Language, ou Encoding. C'est la
    valeur d'option par défaut, et la contrainte la plus stricte
    dont les effets de bord inattendus sont les moins nombreux.
    

    
    Pour inclure des extensions associées avec des gestionnaires
    et/ou des filtres, définissez la directive
    MultiviewsMatch avec les mots-clés
    Handlers, Filters, ou les deux. Si tous
    les autres facteurs sont égaux, c'est le fichier de plus petite
    taille qui sera servi ; par exemple, si le choix doit s'opérer entre
    index.html.cgi de 500 octets et
    index.html.pl de 1000 octets, c'est le fichier
    .cgi qui l'emportera dans cet exemple. Les utilisateurs
    de fichiers .asis auront avantage à utiliser l'option
    Handler, si les fichiers .asis sont associés au
    gestionnaire asis-handler.
    

    
    Vous pouvez enfin autoriser l'association de toute extension avec
    l'option Any, même si mod_mime ne
    reconnaît pas l'extension. Ceci
    peut conduire à des résultats imprévisibles, comme l'envoi de
    fichiers .old ou .bak contrairement aux souhaits du webmaster.
    

    
    Par exemple, la configuration suivante va permettre l'inclusion
    des extensions associées aux gestionnaires et aux filtres dans les
    vues multiples, tout en excluant les fichiers de type inconnu :
    

    
    MultiviewsMatch Handlers Filters
    


    
    L'utilisation de la directive
    MultiviewsMatch dans une section <Location> ou <LocationMatch> n'est pas
    permise.

    chemin-fichier est un chemin relatif au répertoire défini
    par la directive ServerRoot. Ce
    fichier contient la liste des associations par défaut des extensions
    de noms de fichiers aux types de contenus. La plupart des
    administrateurs utilisent le fichier mime.types fourni
    par leur système d'exploitation,
    qui associe les extensions de noms de fichiers courantes à la liste
    officielle des types de média enregistrés par l'IANA et maintenue à
    http://www.iana.org/assignments/media-types/index.html, ainsi
    qu'un grand nombre de types non officiels. Ce fichier permet de
    simplifier le fichier httpd.conf en fournissant la
    majorité des définitions de types de média, et ses définitions
    peuvent être écrasées par des directives AddType, selon les besoins. Il est
    déconseillé de modifier le contenu du fichier
    mime.types car il peut être remplacé lors d'une mise à
    jour du serveur.
    

    
    Le fichier contient des lignes dont le format est identique à
    celui des arguments d'une directive AddType :
    

    
    
      type-médium [extension] ...
    
    

    
    Les extensions sont insensibles à la casse. Les lignes vides et
    les lignes commençant par un dièse (#) sont
    ignorées. Les lignes vides servent à compléter le fichier
    mime.types. Apache httpd peut encore déterminer ces types via le
    module mod_mime_magic.
    

    
    
      Merci de ne pas soumettre de requêtes au Projet
      de Serveur HTTP Apache pour ajouter une entrée dans le fichier
      mime.types fourni, sauf si :
      1) le type de médium est déjà enregistré à l'IANA
      2) et si l'extension est largement acceptée et ne provoque pas de
      conflits d'extensions entre les différentes plate-formes. Les
      requêtes du type catégorie/x-sous-type seront
      systématiquement rejetées, ainsi que toute nouvelle extension de
      deux lettres, car elle ont de fortes chances d'entrer en conflit
      par la suite avec les inombrables langues préexistantes et les
      espaces de nommage des jeux de caractères.

    Description:LDAP connection pooling and result caching services for use
by other LDAP modules
    

    Status:Extension
    

    Module Identifier:ldap_module
    

    Source File:util_ldap.c
    

    Summary
    

    
    This module was created to improve the performance of
    websites relying on backend connections to LDAP servers. In
    addition to the functions provided by the standard LDAP
    libraries, this module adds an LDAP connection pool and an LDAP
    shared memory cache.
    

    
    To enable this module, LDAP support must be compiled into
    apr-util. This is achieved by adding the --with-ldap
    flag to the configure script when building
    Apache.
    

    
    SSL/TLS support is dependent on which LDAP toolkit has been
    linked to APR. As of this writing, APR-util supports:
    OpenLDAP SDK (2.x or later),
    Novell LDAP
    SDK, 
    Mozilla LDAP SDK, native Solaris LDAP SDK (Mozilla based) or the
    native Microsoft LDAP SDK. See the APR
    website for details.

    Example Configuration
    
    
    The following is an example configuration that uses
    mod_ldap to increase the performance of HTTP Basic
    authentication provided by mod_authnz_ldap.
    

    
    # Enable the LDAP connection pool and shared
# memory cache. Enable the LDAP cache status
# handler. Requires that mod_ldap and mod_authnz_ldap
# be loaded. Change the "yourdomain.example.com" to
# match your domain.

LDAPCacheEntries 1024
LDAPCacheTTL 600
LDAPOpCacheEntries 1024

</Location>

    LDAP Connection Pool
    

    
    LDAP connections are pooled from request to request. This
    allows the LDAP server to remain connected and bound ready for
    the next request, without the need to unbind/connect/rebind.
    The performance advantages are similar to the effect of HTTP
    keepalives.
    

    
    On a busy server it is possible that many requests will try
    and access the same LDAP server connection simultaneously.
    Where an LDAP connection is in use, Apache will create a new
    connection alongside the original one. This ensures that the
    connection pool does not become a bottleneck.
    

    
    There is no need to manually enable connection pooling in
    the Apache configuration. Any module using this module for
    access to LDAP services will share the connection pool.
    

    
    LDAP connections can keep track of the ldap client
    credentials used when binding to an LDAP server. These
    credentials can be provided to LDAP servers that do not
    allow anonymous binds during referral chasing. To control
    this feature, see the
    LDAPReferrals and
    LDAPReferralHopLimit
    directives. By default, this feature is enabled.

    LDAP Cache
    

    
    For improved performance, mod_ldap uses an aggressive
    caching strategy to minimize the number of times that the LDAP
    server must be contacted. Caching can easily double or triple
    the throughput of Apache when it is serving pages protected
    with mod_authnz_ldap. In addition, the load on the LDAP server
    will be significantly decreased.
    

    
    mod_ldap supports two types of LDAP caching during
    the search/bind phase with a search/bind cache and
    during the compare phase with two operation
    caches. Each LDAP URL that is used by the server has
    its own set of these three caches.
    

    
    The Search/Bind Cache
    
      
    The process of doing a search and then a bind is the
      most time-consuming aspect of LDAP operation, especially if
      the directory is large. The search/bind cache is used to
      cache all searches that resulted in successful binds.
      Negative results (i.e., unsuccessful searches, or searches
      that did not result in a successful bind) are not cached.
      The rationale behind this decision is that connections with
      invalid credentials are only a tiny percentage of the total
      number of connections, so by not caching invalid
      credentials, the size of the cache is reduced.
    

      
    mod_ldap stores the username, the DN
      retrieved, the password used to bind, and the time of the bind
      in the cache. Whenever a new connection is initiated with the
      same username, mod_ldap compares the password
      of the new connection with the password in the cache. If the
      passwords match, and if the cached entry is not too old,
      mod_ldap bypasses the search/bind phase.
    

      
    The search and bind cache is controlled with the LDAPCacheEntries and LDAPCacheTTL directives.
    
    

    
    Operation Caches
    
      
    During attribute and distinguished name comparison
      functions, mod_ldap uses two operation caches
      to cache the compare operations. The first compare cache is
      used to cache the results of compares done to test for LDAP
      group membership. The second compare cache is used to cache
      the results of comparisons done between distinguished
      names.
    

      
    Note that, when group membership is being checked, any sub-group
      comparison results are cached to speed future sub-group comparisons.
    

      
    The behavior of both of these caches is controlled with
      the LDAPOpCacheEntries
      and LDAPOpCacheTTL
      directives.
    
    

    
    Monitoring the Cache
    
      
    mod_ldap has a content handler that allows
      administrators to monitor the cache performance. The name of
      the content handler is ldap-status, so the
      following directives could be used to access the
      mod_ldap cache information:
    

      
    <Location "/server/cache-info">
    SetHandler ldap-status
</Location>
    


      
    By fetching the URL http://servername/cache-info,
      the administrator can get a status report of every cache that is used
      by mod_ldap cache. Note that if Apache does not
      support shared memory, then each httpd instance has its
      own cache, so reloading the URL will result in different
      information each time, depending on which httpd
      instance processes the request.

    Using SSL/TLS
    

    
    The ability to create an SSL and TLS connections to an LDAP server
    is defined by the directives
    LDAPTrustedGlobalCert,
    LDAPTrustedClientCert
     and LDAPTrustedMode.
    These directives specify the CA and optional client certificates to be used,
    as well as the type of encryption to be used on the connection (none, SSL or
    TLS/STARTTLS).
    

    
    # Establish an SSL LDAP connection on port 636. Requires that
# mod_ldap and mod_authnz_ldap be loaded. Change the
# "yourdomain.example.com" to match your domain.

    SSL/TLS Certificates
    

    
    The different LDAP SDKs have widely different methods of setting
    and handling both CA and client side certificates.
    

    
    If you intend to use SSL or TLS, read this section CAREFULLY so as to
    understand the differences between configurations on the different LDAP
    toolkits supported.
    

    
    Netscape/Mozilla/iPlanet SDK
    
        
    CA certificates are specified within a file called cert7.db.
        The SDK will not talk to any LDAP server whose certificate was
        not signed by a CA specified in this file. If
        client certificates are required, an optional key3.db file may
        be specified with an optional password. The secmod file can be
        specified if required. These files are in the same format as
        used by the Netscape Communicator or Mozilla web browsers. The easiest
        way to obtain these files is to grab them from your browser
        installation.
    

        
    Client certificates are specified per connection using the
        LDAPTrustedClientCert
        directive by referring
        to the certificate "nickname". An optional password may be
        specified to unlock the certificate's private key.
    

        
    The SDK supports SSL only. An attempt to use STARTTLS will cause
        an error when an attempt is made to contact the LDAP server at
        runtime.
    

        
    # Specify a Netscape CA certificate file
LDAPTrustedGlobalCert CA_CERT7_DB "/certs/cert7.db"
# Specify an optional key3.db file for client certificate support
LDAPTrustedGlobalCert CERT_KEY3_DB "/certs/key3.db"
# Specify the secmod file if required
LDAPTrustedGlobalCert CA_SECMOD "/certs/secmod"
<Location "/ldap-status">
    SetHandler ldap-status

    Require host yourdomain.example.com

    Satisfy any
    AuthType Basic
    AuthName "LDAP Protected"
    AuthBasicProvider ldap
    LDAPTrustedClientCert CERT_NICKNAME <nickname> [password]
    AuthLDAPURL "ldaps://127.0.0.1/dc=example,dc=com?uid?one"
    Require valid-user
</Location>
    


    

    
    Novell SDK
    

        
    One or more CA certificates must be specified for the Novell
        SDK to work correctly. These certificates can be specified as
        binary DER or Base64 (PEM) encoded files.
    

        
    Note: Client certificates are specified globally rather than per
        connection, and so must be specified with the LDAPTrustedGlobalCert
        directive as below. Trying to set client certificates via the
        LDAPTrustedClientCert
        directive will cause an error to be logged
        when an attempt is made to connect to the LDAP server.
    

        
    The SDK supports both SSL and STARTTLS, set using the
        LDAPTrustedMode parameter.
        If an ldaps:// URL is specified,
        SSL mode is forced, override this directive.
    

        
    # Specify two CA certificate files
LDAPTrustedGlobalCert CA_DER "/certs/cacert1.der"
LDAPTrustedGlobalCert CA_BASE64 "/certs/cacert2.pem"
# Specify a client certificate file and key
LDAPTrustedGlobalCert CERT_BASE64 "/certs/cert1.pem"
LDAPTrustedGlobalCert KEY_BASE64 "/certs/key1.pem" [password]
# Do not use this directive, as it will throw an error
#LDAPTrustedClientCert CERT_BASE64 "/certs/cert1.pem"
    


    

    
    OpenLDAP SDK
    

        
    One or more CA certificates must be specified for the OpenLDAP
        SDK to work correctly. These certificates can be specified as
        binary DER or Base64 (PEM) encoded files.
    

        
    Both CA and client certificates may be specified globally
        (LDAPTrustedGlobalCert) or
        per-connection (LDAPTrustedClientCert).
        When any settings are specified per-connection, the global
        settings are superseded.
    

        
    The documentation for the SDK claims to support both SSL and
        STARTTLS, however STARTTLS does not seem to work on all versions
        of the SDK. The SSL/TLS mode can be set using the
        LDAPTrustedMode parameter. If an ldaps:// URL is specified,
        SSL mode is forced. The OpenLDAP documentation notes that SSL
        (ldaps://) support has been deprecated to be replaced with TLS,
        although the SSL functionality still works.

    Solaris SDK
    

        
    SSL/TLS for the native Solaris LDAP libraries is not yet
        supported. If required, install and use the OpenLDAP libraries
        instead.
    

    

    
    Microsoft SDK
    

        
    SSL/TLS certificate configuration for the native Microsoft
        LDAP libraries is done inside the system registry, and no
        configuration directives are required.
    

        
    Both SSL and TLS are supported by using the ldaps:// URL
        format, or by using the LDAPTrustedMode directive accordingly.
    

        
    Note: The status of support for client certificates is not yet known
        for this toolkit.

    LDAPCacheEntries Directive
    

    

    Description:Maximum number of entries in the primary LDAP cache

    Context:server config
    

    Status:Extension
    

    Module:mod_ldap
    

    
    
    Specifies the maximum size of the primary LDAP cache. This
    cache contains successful search/binds. Set it to 0 to turn off
    search/bind caching. The default size is 1024 cached

    LDAPConnectionPoolTTL Directive
    

    

    Description:Discard backend connections that have been sitting in the connection pool too long
    

    Syntax:LDAPConnectionPoolTTL n
    

    Default:LDAPConnectionPoolTTL -1
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_ldap
    

    Compatibility:Apache HTTP Server 2.3.12 and later
    

    
    
    Specifies the maximum age, in seconds, that a pooled LDAP connection can remain idle
    and still be available for use.  Connections are cleaned up when they are next needed,
    not asynchronously.
    

    
    A setting of 0 causes connections to never be saved in the backend
    connection pool.  The default value of -1, and any other negative value,
    allows connections of any age to be reused.
    

    
    For performance reasons, the reference time used by this directive is
    based on when the LDAP connection is returned to the pool, not the time
    of the last successful I/O with the LDAP server.  
    

    
    Since 2.4.10, new measures are in place to avoid the reference time
    from being inflated by cache hits or slow requests.  First, the reference
    time is not updated if no backend LDAP conncetions were needed. Second,
    the reference time uses the time the HTTP request was received instead
    of the time the request is completed.
    

    
    This timeout defaults to units of seconds, but accepts
    suffixes for milliseconds (ms), minutes (min), and hours (h).

    LDAPConnectionTimeout Directive

    Syntax:LDAPConnectionTimeout seconds
    

    Context:server config
    

    Status:Extension
    

    Module:mod_ldap
    

    
    
    This directive configures the LDAP_OPT_NETWORK_TIMEOUT (or LDAP_OPT_CONNECT_TIMEOUT)
    option in the underlying LDAP client library, when available.  This value
    typically controls how long the LDAP client library will wait for the TCP
    connection to the LDAP server to complete.
    

    
     If a connection is not successful with the timeout period, either an error will be
    returned or the LDAP client library will attempt to connect to a secondary LDAP
    server if one is specified (via a space-separated list of hostnames in the
    AuthLDAPURL).
    

    
    The default is 10 seconds, if the LDAP client library linked with the
    server supports the LDAP_OPT_NETWORK_TIMEOUT option.
    

    
    LDAPConnectionTimeout is only available when the LDAP client library linked
    with the server supports the LDAP_OPT_NETWORK_TIMEOUT
    (or LDAP_OPT_CONNECT_TIMEOUT) option, and the ultimate behavior is
    dictated entirely by the LDAP client library.

    Context:server config
    

    Status:Extension
    

    Module:mod_ldap
    

    
    
    Turns on SDK-specific LDAP debug options that generally cause the LDAP
    SDK to log verbose trace information to the main Apache error log.
    The trace messages from the LDAP SDK provide gory details that
    can be useful during debugging of connectivity problems with backend LDAP servers
    

    
    This option is only configurable when Apache HTTP Server is linked with
    an LDAP SDK that implements LDAP_OPT_DEBUG or
    LDAP_OPT_DEBUG_LEVEL, such as OpenLDAP (a value of 7 is verbose)
    or Tivoli Directory Server (a value of 65535 is verbose).
    

    
    
    
    The logged information will likely contain plaintext credentials being used or
    validated by LDAP authentication, so care should be taken in protecting and purging
    the error log when this directive is used.

    This directive, if enabled by the LDAPReferrals directive,
    limits the number of referral hops that are followed before terminating an
    LDAP query.
    


    

     Support for this tunable is uncommon in LDAP SDKs.

    Context:directory, .htaccess
    

    Override:AuthConfig

    Module:mod_ldap
    

    Compatibility:The default parameter is available in Apache 2.4.7 and later
    

    
    
    Some LDAP servers divide their directory among multiple domains and use referrals
    to direct a client when a domain boundary is crossed. This is similar to a HTTP redirect.
    LDAP client libraries may or may not chase referrals by default. This directive
    explicitly configures the referral chasing in the underlying SDK.
    


    
    LDAPReferrals takes the following values:
    
    
    
     
    "on"
    
     
     
     When set to "on", the underlying SDK's referral chasing state
              is enabled, LDAPReferralHopLimit is used to
              override the SDK's hop limit, and an LDAP rebind callback is
              registered.
    
     
    "off"
    
     
     
     When set to "off", the underlying SDK's referral chasing state
              is disabled completely.
    
     
    "default"
    
     
     
     When set to "default", the underlying SDK's referral chasing state
              is not changed, LDAPReferralHopLimit is not
              used to override the SDK's hop limit, and no LDAP rebind callback is
              registered.
    
    
    

    
    The directive LDAPReferralHopLimit works in conjunction with
    this directive to limit the number of referral hops to follow before terminating the LDAP query.
    When referral processing is enabled by a value of "On", client credentials will be provided,
    via a rebind callback, for any LDAP server requiring them.

    The server will retry failed LDAP requests up to
    LDAPRetries times.  Setting this

    Module:mod_ldap
    

    Compatibility:Apache HTTP Server 2.3.5 and later
    

    
    
    This directive configures the timeout for bind and search operations, as well as
    the LDAP_OPT_TIMEOUT option in the underlying LDAP client library, when available.
    

    
     If the timeout expires, httpd will retry in case an existing connection has
    been silently dropped by a firewall. However, performance will be much better if
    the firewall is configured to send TCP RST packets instead of silently dropping
    packets.
    

    
    
    
    Timeouts for ldap compare operations requires an SDK with LDAP_OPT_TIMEOUT, such as OpenLDAP >= 2.4.4.

    It specifies the directory path, file name or nickname of a
    per connection client certificate used when establishing an SSL
    or TLS connection to an LDAP server. Different locations or
    directories may have their own independent client certificate
    settings. Some LDAP toolkits (notably Novell)
    do not support per connection client certificates, and will throw an
    error on LDAP server connection if you try to use this directive
    (Use the LDAPTrustedGlobalCert
    directive instead for Novell client
    certificates - See the SSL/TLS certificate guide above for details).
    The type specifies the kind of certificate parameter being
    set, depending on the LDAP toolkit being used. Supported types are:
    
    
      
      
    • CA_DER - binary DER encoded CA certificate

    It specifies the directory path and file name of the trusted CA
    certificates and/or system wide client certificates mod_ldap
    should use when establishing an SSL or TLS connection to an LDAP
    server. Note that all certificate information specified using this directive
    is applied globally to the entire server installation. Some LDAP toolkits
    (notably Novell) require all client certificates to be set globally using
    this directive. Most other toolkits require clients certificates to be set
    per Directory or per Location using LDAPTrustedClientCert. If you get this
    wrong, an error may be logged when an attempt is made to contact the LDAP
    server, or the connection may silently fail (See the SSL/TLS certificate
    guide above for details).

    Summary
    

    
    The Server consists of a main, parent process and a small, static
    number of child processes.
    

    
    The parent process's job is to manage the child processes. This
    involves spawning children as required to ensure there are always
    StartServers processes
    accepting connections.
    

    
    Each child process consists of a pool of worker threads and a
    main thread that accepts connections and passes them to the workers via
    a work queue. The worker thread pool is dynamic, managed by a
    maintenance thread so that the number of idle threads is kept between
    MinSpareThreads and
    MaxSpareThreads.

SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-brotli
    


      
    Si vous voulez restreindre la compression à certains types MIME
      particuliers, vous pouvez utiliser la directive AddOutputFilterByType. Dans l'exemple
      suivant, l'activation de la compression est restreinte aux fichiers html
      de la documentation d'Apache :
    

      
    <Directory "/your-server-root/manual">
    AddOutputFilterByType BROTLI_COMPRESS text/html
</Directory>
    


      
    Note
    
        Le filtre BROTLI_COMPRESS est toujours inséré après les
	filtres RESOURCE comme PHP ou SSI. Il n'affecte jamais les sous-requêtes
	internes.
      
    
      
    Note
    
        Définie via SetEnv, la variable
	d'environnement no-brotli permet de désactiver la
	compression brotli pour une requête particulière, et ceci même si elle
	est supportée par le client.

    Interaction avec les serveurs mandataires
    

    
    Le module mod_brotli envoie un en-tête de réponse HTTP
    Vary:Accept-Encoding pour indiquer aux mandataires qu'une
    réponse mise en cache ne doit être envoyée qu'aux clients qui envoient
    l'en-tête de requête Accept-Encoding approprié. Ceci permet
    d'éviter d'envoyer du contenu compressé à un client qui ne sera pas en
    mesure de le décompresser.
    

    
    Si vous utilisez des exclusions spéciales dépendant, par exemple, de
    l'en-tête User-Agent, vous devez faire un ajout manuel à
    l'en-tête Vary afin d'informer les mandataires des restrictions
    supplémentaires. Par exemple, dans une configuration typique où l'addition
    du filtre BROTLI_COMPRESS dépend de l'en-tête User-Agent,
    vous devez ajouter :
    

    
    Header append Vary User-Agent
    


    
    Si votre décision d'utiliser la compression ou non dépend d'autres
    informations que le contenu d'en-têtes de requêtes (par exemple la version
    HTTP), vous devez affecter la valeur * à l'en-tête
    Vary. Ceci permet d'éviter que des mandataires qui le
    supportent n'effectuent une mise en cache intégrale.
    

    
    Exemple
    Header set Vary *
    

    

    top
    

    

    Servir un contenu pré-compressé
    

    
    comme mod_brotli compresse systématiquement un contenu
    pour chaque requête le concernant, il est possible d'obtenir un gain en
    performance en pré-compressant le contenu et en disant à mod_brotli de le
    servir sans le recompresser. Pour cela, vous pouvez utiliser une
    configuration du style :
    

    
    <IfModule mod_headers.c>
    # Sert des fichiers CSS compressés par brotli, s'ils existent
    # et si le client supporte brotli.
    RewriteCond "%{HTTP:Accept-encoding}" "br"
    RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
    RewriteRule "^(.*)\.css"              "$1\.css\.br" [QSA]

    # Sert des fichiers JS compressés par brotli, s'ils existent
    # et si le client supporte brotli.
    RewriteCond "%{HTTP:Accept-encoding}" "br"
    RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
    RewriteRule "^(.*)\.js"               "$1\.js\.br" [QSA]


    # Sert des types de contenu corrects, et évite la double compression.
    RewriteRule "\.css\.gz$" "-" [T=text/css,E=no-brotli:1]
    RewriteRule "\.js\.gz$"  "-" [T=text/javascript,E=no-brotli:1]


    <FilesMatch "(\.js\.br|\.css\.br)$">
      # Sert un type d'encodage correct.
      Header append Content-Encoding br

      # Force les mandataires à mettre en cache séparément les fichiers css/js
      # compressés ou non par brotli.
      Header append Vary Accept-Encoding
    </FilesMatch>
</IfModule>

    comment l'en-tête ETag doit être modifié lorsqu'une réponse est compressée.
    
    
    
    
    AddSuffix
    
    
    Ajoute la méthode de compression à la fin de l'en-tête ETag, ce qui
    implique que les représentations compressées et non compressées possèderont
    des en-têtes ETag uniques. C'est le comportement par défaut depuis la
    version 2.4.0 avec un autre module de compression dynamique,
    mod-deflate. Ce paramètre permet d'éviter l'envoi de messages
    "HTTP Not Modified" (304) en réponse aux requêtes conditionnelles pour des
    contenus compressés.
    
    
    NoChange
    
    
    Ne modifie pas l'en-tête ETag d'une réponse compressée. C'était le
    comportement par défaut avant la version 2.4.0 avec un autre module de
    compression dynamique, mod-deflate. Ce paramètre ne respecte pas la
    propriété HTTP/1.1 selon laquelle toutes les représentations d'une même
    ressource ont des en-têtes ETag uniques.
    
    
    Remove
    
    
    Supprime l'en-tête ETag des réponses compressées, ce qui rend
    impossibles certaines requêtes conditionnelles, mais évite les inconvénients
    des options précédentes.

    La directive BrotliFilterNote permet d'indiquer
    qu'une note à propos du taux de compression doit être attachée à la
    requête. L'argument notename permet de spécifier le nom de la
    note. Vous pouvez utiliser cette note à des fins de statistiques en ajoutant
    l'information correspondante à votre access
    log.
    

    
    Exemple
    BrotliFilterNote ratio

LogFormat '"%r" %b (%{ratio}n) "%{User-agent}i"' brotli
CustomLog "logs/brotli_log" brotli
    

    

    
    Si vous souhaitez que l'information enregistrée dans vos journaux soit
    plus pertinente, vous pouvez renseigner l'argument optionnel type
    afin de spécifier le type de données à enregistrer dans la note à
    journaliser. L'argument type accepte les valeurs suivantes :
    

    
    
      
    Input
    
      
    Enregistre dans la note le nombre d'octets contenus dans le flux
      d'entrée du filtre.
    

      
    Output
    
      
    Enregistre dans la note le nombre d'octets contenus dans le flux
      de sortie du filtre.
    

      
    Ratio
    
      
    Enregistre dans la note le taux de compression (output/input *
      100). Il s'agit de l'option par défaut si l'argument
      type est omis.
    
    
    

    
    Vous pouvez alors configurer vos journaux de la manière suivante :
    

    
    Journalisation spécifique
    BrotliFilterNote Input instream
BrotliFilterNote Output outstream
BrotliFilterNote Ratio ratio

LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' brotli
CustomLog "logs/brotli_log" brotli

    Serveur HTTP Apache Version 2.4

    Module Apache mod_proxy_http2
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Support de HTTP/2 pour mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_http2_module
    

    Fichier Source:mod_proxy_http2.c
    

    Compatibilité:Disponible à partir de la version 2.4.19 du serveur HTTP Apache
    

    Sommaire
    

    
    mod_proxy_http2 ne
    supporte que HTTP/2 et ne permet pas de rétrogradation vers HTTP/1.1. Cela
    signifie que le serveur d'arrière-plan doit supporter HTTP/2 car HTTP/1.1 ne
    pourra alors pas être utilisé.
    

    
    Ce module nécessite la présence de mod_proxy ;
    pour pouvoir traiter les requêtes mandatées HTTP/2,
    mod_proxy et mod_proxy_http2 doivent donc
    être chargés par le serveur.
    

    
    mod_proxy_http2 travaille avec des requêtes entrantes en
    HTTP/1.1 ou HTTP/2. Dans les deux cas, les requêtes vers le même serveur
    d'arrière-plan sont envoyées
    via une seule connexion TCP, dans la mesure du possible (autrement dit
    lorsque la connexion peut être réutilisée).
    

    
    Avertissement : il ne sera effectué aucune tentative de fusion de
    plusieurs requêtes entrantes HTTP/1 (devant être mandatées vers le même
    serveur d'arrière-plan) vers des flux HTTP/2 appartenant à la même requête
    HTTP/2.  Chaque requête HTTP/1 entrante sera mandatée vers le serveur
    d'arrière-plan en utilisant une requête HTTP/2 séparée (tout en réutilisant
    si possible la même connexion TCP).
    

    
    Ce module s'appuie sur libnghttp2 pour
    fournir le moteur central http/2.
    

    
    Avertissement
    
    
    Ce module en est au
    stade expérimental. Ses comportement, directives et valeurs par défauts sont
    donc susceptibles de modifications d'une version à l'autre plus fréquentes
    que pour les autres modules. A ce titre, il est fortement conseillé aux
    utilisateurs de consulter le fichier "CHANGES" pour prendre connaissance de
    ces modifications.
     
    

    
    Avertissement
    
      
    N'activez pas le mandatement avant d'avoir sécurisé votre serveur. Les serveurs
      mandataires ouverts sont dangereux non seulement pour votre propre réseau,
      mais aussi pour l'Internet au sens large.
    
    
    

    


    top
    

    

    Exemples de base
    

    
    Les exemples ci-dessous montrent comment configurer HTTP/2 pour des
    connexions d'arrière-plan vers un mandataire inverse.
    

    
    HTTP/2 (TLS)
    ProxyPass "/app" "h2://app.example.com"
ProxyPassReverse "/app" "https://app.example.com"
    

    

    
    HTTP/2 (non sécurisé)
    ProxyPass "/app" "h2c://app.example.com"
ProxyPassReverse "/app" "http://app.example.com"
    

    

    
    
      
    Pour mandater en inverse les protocoles h2 ou
      h2c, on utilise la directive
      ProxyPassReverse avec les schèmes habituels
      https et respectivement
      http qui sont connus et utilisés par l'agent utilisateur.
    
    
    
    
    top
    

    

    Informations sur les requêtes
    
    
    mod_proxy_http fournit les informations sur les requêtes
    suivantes pour enregistrement dans les journaux en utilisant le format
    %{VARNAME}n avec les directives LogFormat ou ErrorLogFormat :
    
    
    
    
        
    proxy-source-port
    
        
    Le numéro de port local utilisé pour la connexion vers le serveur
	d'arrière-plan.
    
        
    proxy-status
    
        
    Le statut HTTP/2 en provenance du serveur d'arrière-plan.

la répartition de charge
    

    Statut:Extension
    

    Identificateur de Module:proxy_balancer_module
    

    Fichier Source:mod_proxy_balancer.c
    

    Compatibilité:Disponible depuis la version 2.1 d'Apache
    

    Sommaire
    

    
    Pour pouvoir fonctionner, ce module requiert le
    chargement de mod_proxy, et il fournit le support de
    la répartition de charge pour tous les protocoles supportés. Parmi ces
    protocoles, les plus importants sont :
    
    
    

    
    L'algorithme de planification de la répartition de charge n'est pas
    fourni par ce module, mais par ceux-ci :
    
    

    
    Ainsi, pour mettre en oeuvre la répartition de charge,
    mod_proxy, mod_proxy_balancer et
    au moins un des modules fournissant l'algorithme de planification de
    la répartition de charge doivent être chargés dans le serveur.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large.
    
    
    

    


    top
    

    

    L'algorithme de planification de la répartition de
    charge
    
    
    
    A l'heure actuelle, 4 algorithmes de planification de la répartition de
    charge sont disponibles : ils se basent respectivement sur le comptage des
    requêtes (mod_lbmethod_byrequests), la mesure de
    l'intensité du trafic (mod_lbmethod_bytraffic), le comptage
    des requêtes en attente (mod_lbmethod_bybusyness) et la
    mesure de l'activité du serveur (mod_lbmethod_heartbeat).
    Ils sont contrôlés par la valeur de lbmethod dans la définition
    du répartiteur.  Voir la directive ProxyPass pour plus de détails, et en
    particulier la configuration du répartiteur et de ses membres.
    

    top
    

    

    Répartition de charge avec abonnement utilisateur
    (stickyness)
    
    
    
    Le répartiteur supporte l'abonnement utilisateur. Lorsqu'une
    requête est mandatée vers un serveur d'arrière-plan particulier,
    toutes les requêtes suivantes du même utilisateur seront alors
    mandatées vers le même serveur d'arrière-plan. De nombreux
    répartiteurs de charge implémentent cette fonctionnalité via une
    table qui associe les adresses IP des clients aux serveurs
    d'arrière-plan. Cette approche est transparente aux clients et aux
    serveurs d'arrière-plan, mais induit certains problèmes :
    distribution de charge inégale si les clients se trouvent eux-mêmes
    derrière un mandataire, erreurs d'abonnement lorsqu'un client
    possède une adresse IP dynamique qui peut changer au cours d'une
    session et perte d'abonnement en cas de dépassement de la table de
    correspondances.
    
    
    Le module mod_proxy_balancer implémente
    l'abonnement selon deux alternatives : les cookies et le codage
    d'URL. Le cookie peut être fourni par le serveur d'arrière-plan ou
    par le serveur web Apache lui-même, alors que le codage d'URL est en
    général effectué par le serveur d'arrière-plan.
    


    top
    

    

    Exemples de configuration d'un répartiteur
    
    
    
    Avant de nous plonger dans les détails techniques, voici un
    exemple d'utilisation de mod_proxy_balancer mettant
    en oeuvre la répartition de charge entre deux serveurs
    d'arrière-plan :
    
    

    
    <Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80"
    BalancerMember "http://192.168.1.51:80"
</Proxy>
ProxyPass        "/test" "balancer://mycluster"
ProxyPassReverse "/test" "balancer://mycluster"
    



    
    Voici un autre exemple de répartiteur de charge avec
    abonnement utilisant mod_headers,
    fonctionnant même si le serveur d'arrière-plan ne définit pas de
    cookie de session approprié :
    
    

    
    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED
<Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80" route=1
    BalancerMember "http://192.168.1.51:80" route=2
    ProxySet stickysession=ROUTEID
</Proxy>
ProxyPass        "/test" "balancer://mycluster"
ProxyPassReverse "/test" "balancer://mycluster"
    



    top
    

    

    Variables d'environnement exportées
    
    
    
    A l'heure actuelle, 6 variables d'environnement sont exportées :
    

    
    
    
    
    BALANCER_SESSION_STICKY
    
    
    
    
    Cette variable se voir assignée la valeur de
    stickysession pour la requête courante. Il s'agit du
    nom du cookie ou du paramètre de requête utilisé pour les sessions
    avec abonnement.
    
    
    

    
    
    BALANCER_SESSION_ROUTE
    
    
    
    
    Cette variable se voit assignée la route interprétée
    pour la requête courante.
    
    
    

    
    
    BALANCER_NAME
    
    
    
    
    Cette variable se voit assigné le nom du répartiteur pour la
    requête courante. Il s'agit d'une valeur du style
    balancer://foo.
    
    
    

    
    
    BALANCER_WORKER_NAME
    
    
    
    
    Cette variable se voit assigné le nom du membre du groupe de
    répartition de charge utilisé pour la requête courante. Il s'agit
    d'une valeur du style http://hostA:1234.
    
    
    

    
    
    BALANCER_WORKER_ROUTE
    
    
    
    
    Cette variable se voit assignée la route du membre du
    groupe de répartition de charge qui sera utilisé pour la requête
    courante.
    
    
    

    
    
    BALANCER_ROUTE_CHANGED
    
    
    
    
    Cette variable est définie à 1 si la route de la session ne
    correspond pas à celle du membre du groupe de répartition de charge
    (BALANCER_SESSION_ROUTE != BALANCER_WORKER_ROUTE), ou si la session
    ne possède pas encore de route établie. Elle peut servir à
    déterminer quand il est éventuellement nécessaire d'envoyer au
    client une route mise à jour lorsque les sessions persistantes sont
    utilisées.

    Activation du support du gestionnaire de répartiteur
    
    
    
    Cette fonctionnalité nécessite le chargement du module
    mod_status. Le gestionnaire de répartiteur permet
    la mise à jour dynamique des membres du groupe de répartition de
    charge. Vous pouvez utiliser le gestionnaire de répartiteur pour
    modifier le facteur de charge d'un membre particulier, ou passer ce
    dernier en mode hors ligne.
    
    

    
    Ainsi, pour mettre en oeuvre la gestion du répartiteur de charge,
    mod_status et mod_proxy_balancer
    doivent être chargés dans le serveur.
    

    
    Pour permettre la gestion du répartiteur de charge aux
    navigateurs appartenant au domaine example.com, ajoutez ces lignes à
    votre fichier de configuration httpd.conf :
    

    <Location "/balancer-manager">
    SetHandler balancer-manager
    Require host example.com
</Location>
    


    
    Vous pourrez alors accéder au gestionnaire du répartiteur de
    charge en utilisant un navigateur web pour afficher la page
    http://nom.de.votre.serveur/balancer-manager. Notez que
    pour pouvoir contrôler dynamiquement un membre de groupe de
    répartition, ce dernier ne doit pas être défini au sein d'une
    section <Location ...>.

    Détails à propos de la répartition de charge par abonnement
    (stickyness)
    
    
    
    Si l'abonnement s'appuie sur un cookie, vous devez définir le nom
    de ce cookie dont le contenu précise le serveur d'arrière-plan à
    utiliser. Pour ce faire, on utilise l'attribut
    stickysession avec la directive ProxyPass ou ProxySet. Le nom du cookie est
    sensible à la casse. Le répartiteur extrait le contenu du cookie et
    recherche un serveur membre dont la route correspond à
    cette valeur. La route doit aussi être définie dans la directive ProxyPass ou ProxySet. Le cookie peut être défini
    soit par le serveur d'arrière-plan, soit, comme indiqué dans l'exemple ci-dessus par le serveur web Apache
    lui-même.
    
    
    Certains serveurs d'arrière-plan, tels qu'Apache Tomcat,
    utilisent une forme sensiblement différente de cookie d'abonnement.
    Tomcat ajoute le nom de l'instance Tomcat à la fin de son
    identifiant de session, précédé par un point. Ainsi, si le serveur
    web Apache trouve un point dans la valeur du cookie d'abonnement, il
    n'utilisera que la partie située après ce point pour
    rechercher sa route. Pour que Tomcat puisse connaître son nom
    d'instance, vous devez définir l'attribut jvmRoute dans
    son fichier de configuration conf/server.xml à la
    valeur de la route du serveur qui se connecte au Tomcat
    considéré. Le nom du cookie de session utilisé par Tomcat (et plus
    généralement par les applications web Java à base de servlets) est
    JSESSIONID (en majuscules), mais peut être modifié.
    

    
    La seconde méthode pour implémenter l'abonnement est le codage
    d'URL. Ici, le serveur web recherche un paramètre dans l'URL de la
    requête. Le nom du paramètre est spécifié par l'attribut
    stickysession. Pour trouver un serveur membre, on
    recherche un serveur dont la route est égale à la valeur
    du paramètre. Comme il n'est pas aisé d'extraire et de manipuler
    tous les liens URL contenus dans les réponses, le travail consistant
    à ajouter les paramètres à chaque lien est généralement effectué par
    le serveur d'arrière-plan qui génère le contenu. Bien qu'il soit
    possible dans certains cas d'effectuer ces ajouts au niveau du
    serveur web via les modules mod_substitute ou
    mod_sed, cette méthode peut dégrader les
    performances.
    

    
    Les standards Java implémentent le codage d'URL de manière
    sensiblement différente. Ils ajoutent une information de chemin à
    l'URL en utilisant un point-virgule (;) comme
    séparateur, puis ajoutent enfin l'identifiant de session. Comme dans
    le cas des cookies, Apache Tomcat peut insérer la valeur de
    l'attribut jvmRoute dans cette information de chemin.
    Pour qu'Apache puisse trouver ce genre d'information de chemin, vous
    devez définir scolonpathdelim à On dans la
    directive ProxyPass ou
    ProxySet.
    

    
    Enfin, vous pouvez utiliser simultanément les cookies et le codage
    d'URL en définissant le nom du cookie et le nom du paramètre d'URL
    séparés par une barre verticale (|) comme dans
    l'exemple suivant :
    
    
    ProxyPass "/test" "balancer://mycluster" stickysession=JSESSIONID|jsessionid scolonpathdelim=On
<Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80" route=node1
    BalancerMember "http://192.168.1.51:80" route=node2
</Proxy>
    

    
    Si le cookie et le paramètre de requête fournissent tous deux une
    information de route correcte pour la même requête, c'est
    l'information en provenance du paramètre de requête qui sera
    retenue.

    Résolution des problèmes liés à la répartition de charge par
    abonnement
    
    
    
    Si vous êtes confronté à des erreurs d'abonnement, comme la
    nécessité pour les utilisateurs de se reconnecter suite à une perte
    de session d'application, vous devez tout d'abord vérifier si ceci
    n'est pas du à une indisponibilité sporadique des serveurs
    d'arrière-plan ou à une erreur de configuration. La présence de
    messages d'erreur de type proxy dans le journal des erreurs d'Apache
    pourra révéler des problèmes de stabilité au niveau des serveurs
    d'arrière-plan.
    
    
    Pour contrôler votre configuration, regardez tout d'abord si
    l'abonnement est à base de cookie ou de codage d'URL. L'étape
    suivante consiste à enregistrer certaines données dans le journal
    des accès en utilisant un format
    de journalisation personnalisé. Les champs intéressants
    sont les suivants :
    
    
    
    
    %{MONCOOKIE}C
    
    
    La valeur que contient le cookie de nom MONCOOKIE.
    Le nom doit correspondre au nom défini par l'attribut
    stickysession.
    
    
    %{Set-Cookie}o
    
    
    Ce champ contient tout cookie défini par le serveur
    d'arrière-plan. Vous pouvez ainsi vérifier si le serveur
    d'arrière-plan définit bien le cookie de session auquel vous vous
    attendez, et à quelle valeur il est défini.
    
    
    %{BALANCER_SESSION_STICKY}e
    
    
    Le nom du cookie ou du paramètre de requête utilisé pour la
    recherche de l'information de routage.
    
    
    %{BALANCER_SESSION_ROUTE}e
    
    
    L'information de routage extraite de la requête.
    
    
    %{BALANCER_WORKER_ROUTE}e
    
    
    La route du serveur choisi.
    
    
    %{BALANCER_ROUTE_CHANGED}e
    
    
    Contient la valeur 1 si la route extraite de la
    requête est différente de la route du serveur ; autrement dit, le
    traitement de la requête n'a pas pu être effectué dans le cadre
    d'une répartition de charge par abonnement.
    
    
    
    
    Les pertes de session sont souvent dues à des expirations de
    session dont la valeur peut en général être configurée au niveau du
    serveur d'arrière-plan.
    
    
    Si le niveau de journalisation est défini à debug ou
    plus, le répartiteur journalise aussi des informations détaillées à
    propos de l'abonnement dans le journal des erreurs, ce qui facilite
    la résolution des problèmes d'abonnement. Notez cependant que le
    volume de journalisation pourra alors s'avérer trop important pour
    un serveur en production sous forte charge.

    Sommaire
    

    
    Il s'agit d'une émulation de la sémantique des métafichiers du
    serveur httpd du CERN. Les métafichiers consistent en en-têtes HTTP
    qui peuvent s'ajouter au jeu d'en-têtes habituels pour chaque
    fichier accédé. Ils ressemblent beaucoup aux fichiers .asis
    d'Apache, et permettent d'influencer de manière rudimentaire
    l'en-tête Expires:, ainsi que d'autres curiosités. Il existe de
    nombreuses méthodes pour gérer les métainformations, mais le choix
    s'est porté sur celle-ci car il existe déjà un grand nombre
    d'utilisateurs du CERN qui peuvent exploiter ce module.

    Fichier Source:mod_dialup.c
    

    Sommaire
    


    Il s'agit d'un module qui envoie le contenu statique avec une bande
passante limitée définie par les différents standards des anciens
modems. Ainsi, il est possible de naviguer sur votre site avec un modem
56k V.92 en positionnant une configuration de ce type :
    


    <Location "/mysite">
    ModemStandard "V.92"
</Location>
    



    Auparavant, pour faire des modules de limitation de bande passante,
il fallait monopoliser un thread, pour chaque client, et insérer des
temporisations pour diminuer la bande passante. Grâce à cette nouvelle
fonctionnalité, un gestionnaire peut recevoir les réponses à ses
callbacks après N millisecondes, et il sera invoqué par le module MPM
Event dans un thread différent à la fin du délai indiqué. À partir de ce
moment, le gestionnaire peut continuer à envoyer des données au
client.

    Description:Conserve le corps de la requête à concurrence de la taille

comme mod_include.

    Dans une situation normale, les gestionnaires de requête tels que
    le gestionnaire par défaut des fichiers statiques suppriment le
    corps de la requête s'il n'est pas nécessaire au gestionnaire de
    requête. Il en résulte que les filtres comme mod_include sont
    limités à des requêtes GET lors de l'inclusion d'autres
    URLs en tant que sous-requêtes, et ceci même si la requête originale
    était une requête POST, car le corps de la requête a
    été supprimé et n'est donc plus disponible une fois le traitement du
    filtre mis en oeuvre.
    

    
    Lorsque l'argument de cette directive a une valeur supérieure à
    zéro, les gestionnaires de requête qui suppriment habituellement les
    corps de requête vont alors conserver ces corps de requête, à
    concurrence de la taille maximale spécifiée, pour être
    éventuellement utilisés par des filtres. Dans le cas du filtre
    mod_include, une tentative de requête POST pour un
    fichier shtml statique se traduira par des sous-requêtes
    POST, et non par des sous-requêtes GET
    comme avant.
    

    
    Cette fonctionnalité permet de découper des pages web complexes
    et des applications web en petits éléments individuels, et de
    combiner ces éléments avec la structure de la page web sous-jacente
    en utilisant mod_include. Les éléments peuvent se
    présenter sous la forme de programmes CGI, de langages de scripts,
    ou d'URLs issues d'un mandataire inverse dans l'espace d'URL d'un
    autre serveur en utilisant mod_proxy.
    

    
    Note : Chaque requête dont le corps est ainsi
    conservé doit être enregistrée temporairement en mémoire vive
    jusqu'à la fin du traitement de la requête. Il faut donc s'assurer
    que la mémoire RAM du serveur est suffisante pour pouvoir supporter
    la charge induite. L'utilisation de cette directive doit être
    limitée à certaines portions de votre espace d'URL bien précises qui
    le nécessitent, et en spécifiant comme taille maximale une valeur la
    plus petite possible, mais tout de même suffisante pour un corps de
    requête.
    

    
    Si la taille de la requête envoyée par le client dépasse la taille
    maximale autorisée par cette directive, le serveur renverra l'erreur
    413 Request Entity Too Large.

    Sommaire
    


    Ce module ne fournit pas lui-même de directive de configuration. Il
nécessite les services de mod_proxy_balancer, et
fournit la méthode de répartition de charge byrequests.
    

    


    top
    

    

    Algorithme d'attribution des requêtes
    
    
    
    Activé via lbmethod=byrequests, ce planificateur a
    été conçu dans le but de distribuer les requêtes à tous les
    processus worker afin qu'ils traitent tous le nombre de requêtes
    pour lequel ils ont été configurés. Il fonctionne de la manière
    suivante : 
    

    
    lbfactor correspond à la quantité de travail que
    nous attendons de ce processus worker, ou en d'autres termes
    son quota de travail. C'est une valeur normalisée
    représentant leur part du travail à accomplir.
    

    
    lbstatus représente combien il est urgent que
    ce processus worker travaille pour remplir son quota de
    travail.
    

    
    Le worker est un membre du dispositif de répartition
    de charge, en général un serveur distant traitant un des protocoles
    supportés.
    

    
    On distribue à chaque processus worker son quota de travail, puis
    on regarde celui qui a le plus besoin de travailler
    (le plus grand lbstatus). Ce processus est alors sélectionné pour
    travailler, et son lbstatus diminué de l'ensemble des quotas de
    travail que nous avons distribués à tous les processus. La somme de
    tous les lbstatus n'est ainsi pas modifiée, et nous pouvons
    distribuer les requêtes selon nos souhaits.
    

    
    Si certains processus workers sont désactivés, les autres feront
    l'objet d'une planification normale.
    

    
    for each worker in workers
    worker lbstatus += worker lbfactor
    total factor    += worker lbfactor
    if worker lbstatus > candidate lbstatus
        candidate = worker

candidate lbstatus -= total factor
    

    
    Si un répartiteur de charge est configuré comme suit :
    

    
    worker
        a
        b
        c
        d
    

    lbfactor
        25
        25
        25
        25
    

    lbstatus
        0
        0
        0
        0
    

    

    
    Et si b est désactivé, la planification suivante est
    mise en oeuvre :
    

    
    worker
        a
        b
        c
        d
    

    lbstatus
        -50
        0
        25
        25
    

    lbstatus
        -25
        0
        -25

Terms Used to Describe Modules - Apache HTTP Server Version 2.4

    Terms Used to Describe Modules
    

    

    Available Languages:  en  |

 tr 
    

    

   
    This document describes the terms that are used to describe
    each Apache module.
    

    


    top
    

    

    Description
    


    A brief description of the purpose of the module.
    

    top
    

    

    Status
    

    
    This indicates how tightly bound into the Apache Web server
    the module is; in other words, you may need to recompile the
    server in order to gain access to the module and its
    functionality. Possible values for this attribute are:
    

    
    
      
    MPM
    

      
    A module with status "MPM" is a Multi-Processing Module. Unlike the
      other types of modules, Apache must have one and only one MPM
      in use at any time. This type of module is responsible for
      basic request handling and dispatching.
    

      
    Base
    

      
    A module labeled as having "Base" status is compiled and
      loaded into the server by default, and is therefore normally
      available unless you have taken steps to remove the module
      from your configuration.
    

      
    Extension
    

      
    A module with "Extension" status is not normally compiled
      and loaded into the server. To enable the module and its
      functionality, you may need to change the server build
      configuration files and re-compile Apache.
    

      
    Experimental
    

      
    "Experimental" status indicates that the module is
      available as part of the Apache kit, but you are on your own
      if you try to use it. The module is being documented for
      completeness, and is not necessarily supported.
    

      
    External
    

      
    Modules which are not included with the base Apache
      distribution ("third-party modules") may use the "External"
      status. We are not responsible for, nor do we support such
      modules.
    
    
    

    top
    

    

    Source File
    

    
    This quite simply lists the name of the source file which
    contains the code for the module. This is also the name used by
    the <IfModule>
    directive.
    

    top
    

    

    Module Identifier
    

    
    This is a string which identifies the module for use in the
    LoadModule directive when
    dynamically loading modules. In particular, it is the name of
    the external variable of type module in the source file.
    

    top
    

    

    Compatibility
    

    
    If the module was not part of the original Apache version 2
    distribution, the version in which it was introduced should be
    listed here.  In addition, if the module is limited to
    particular platforms, the details will be listed here.

    Sommaire
    

    
    mod_substitute fournit un mécanisme permettant
    d'effectuer des substitutions de chaînes fixes ou d'expressions
    rationnelles sur les corps de réponses.
    

    



    top
    

    Directive Substitute
    

    

    Description:Modèle de substition dans le contenu de la
réponse
    

    Syntaxe:Substitute s/modèle/substitution/[infq]
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_substitute
    

    
    
    La directive Substitute permet de
    spécifier un modèle de recherche/remplacement à appliquer au corps
    de la réponse.
    

    
    La signification du modèle peut être modifiée via toute
    combinaison de ces drapeaux :
    

    
    
        
    i
    
        
    Effectue une comparaison sans tenir compte de la casse.
    
        
    n
    
        
    Par défaut, le modèle est traité en tant qu'expression
	rationnelle. Le drapeau n force le traitement du
	modèle en tant que chaîne fixe.
    
        
    f
    
	
        
    Avec le drapeau f, mod_substitute met à plat le
	résultat d'une substitution (les conteneurs ou buckets ne sont
	pas dissociés), ce qui permet à d'éventuelles substitutions
	ultérieures de s'effectuer sur cette dernière. C'est le
	comportement par défaut.
    
        
    q
    
	
        
    Avec le drapeau q, mod_substitute dissocie les
	conteneurs (ou buckets) après chaque substitution. Ceci peut
	améliorer la rapidité de la réponse et diminuer la quantité de
	mémoire utilisée, mais ne doit être utilisé que s'il n'existe
	aucune possibilité pour que le résultat d'une substitution ne
	corresponde au modèle ou à l'expression rationnelle d'une
	substitution ultérieure.
    
    
    

    
    substitution peut contenir du texte et des références arrières
    d'expressions rationnelles.
    

    
    Exemple
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    Substitute "s/foo/bar/ni"
</Location>
    

    

    
    Le caractère utilisé pour séparer (ou "délimiter") les différentes partie
    de la valeur de substitution est référencé sous le nom de "délimiteur", et
    il s'agit le plus souvent d'un "slash".
    

    
    Si le modèle ou la chaîne de substitution contient un caractère
    slash '/', il est possible d'utiliser un autre délimiteur afin de rendre la
    directive plus lisible :
    

    
    Exemple d'utilisation d'un délimiteur
    alternatif
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    Substitute "s|<BR */?>|<br />|i"
</Location>
    

    

    
    Lorsqu'on utilise des expressions rationnelles, on peut insérer
    des références arrières dans les opérations de comparaison et de
    substitution, comme illustré dans l'exemple suivant :
    
    
    Exemple d'utilisation de références arrières et de captures
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    # "foo=k,bar=k" -> "foo/bar=k"
    Substitute "s|foo=(\w+),bar=\1|foo/bar=$1|"
</Location>
    

    

    
    Un scénario courant d'utilisation de mod_substitute
    est la situation où un serveur frontal mandate des requêtes pour un
    serveur d'arrière-plan qui renvoie des documents HTML contenant des
    URLs intégrées codées en dur qui font référence à ce serveur
    d'arrière-plan. Ces URLs ne fonctionnent pas pour l'utilisateur
    final car le serveur d'arrière-plan est hors d'atteinte.
    

    
    On peut, dans ce cas, utiliser mod_substitute pour
    réécrire ces URLs afin qu'elles soit utilisables dans la partie
    située derrière le mandataire :
    

    
    Réécriture des URLs intégrées à un contenu mandaté
    ProxyPass        "/blog/" "http://internal.blog.example.com/"
ProxyPassReverse "/blog/" "http://internal.blog.example.com/"

Substitute "s|http://internal.blog.example.com/|http://www.example.com/blog/|i"
    

    

    
    La directive ProxyPassReverse modifie tout en-tête
    Location (redirection) envoyé par le serveur
    d'arrière-plan et, dans cet exemple, la directive
    Substitute se charge à son tour de la modification de
    la réponse HTML.

    Cette directive permet de définir si l'on applique les modèles
Substitute hérités en premier
(valeur on), ou après ceux du
contexte courant (valeur off). La valeur de la directive
SubstituteInheritBefore est
elle-même héritée, et les contextes qui en héritent (ceux qui ne
définissent pas explicitement leur propre directive
SubstituteInheritBefore) appliqueront donc
l'ordre de fusion défini le plus proche.

    Description:Définit la longueur de ligne maximale
    

    Syntaxe:SubstituteMaxLineLength octets(b|B|k|K|m|M|g|G)
    

    Défaut:SubstituteMaxLineLength 1m

Apache
    

    
    
    La taille de la ligne traitée par mod_substitute
    est limitée afin de restreindre l'utilisation des ressources
    mémoire. La directive SubstituteMaxLineLength
    permet de définir cette limite. La valeur de la limite peut être
    spécifiée sous la forme d'un nombre d'octets, et peut être suffixée
    par une des lettres b, B, k,
    K, m, M, g ou
    G pour fournir une valeur respectivement en octets,
    kiloOctets, mégaOctets ou gigaOctets.
    

    
    Example
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    SubstituteMaxLineLength 10m
    Substitute "s/foo/bar/ni"
</Location>

    Description:Managing domains across virtual hosts, certificate provisioning 
        via the ACME protocol
    
    

    Status:Experimental
    

    Module Identifier:md_module
    

    Source File:mod_md.c
    

    Compatibility:Available in version 2.4.30 and later
    

    Summary
    

        
    
        This module manages common properties of domains for one or more virtual hosts. 
        Its serves two main purposes: for one, supervise/renew https: certificates via the 
        ACME protocol (RFC 8555). 
        Certificates will be renewed by the module ahead of their expiration to account 
        for disruption in internet services. There are ways to monitor the status of all 
        certififcates managed this way and configurations that will run your own 
        notification commands on renewal, expiration and errors.
        
    
        Second, mod_md offers an alternate OCSP Stapling implementation. This works with
        managed certificates as well as with certificates you configure yourself. OCSP
        Stapling is a necessary component for any https: site, influencing page load
        times and, depending on other setups, page availability. More in the
        stapling section below.
        
    
        The default ACME Authority for managing certificates is 
        Let's Encrypt, but it is possible 
        to configure another CA that supports the protocol.
        
    
        
        
    Simple configuration example:
    
        
        
    TLS in a VirtualHost context
    
        
    MDomain example.org

<VirtualHost *:443>
    ServerName example.org
    DocumentRoot htdocs/a

    SSLEngine on
    # no certificates specification
</VirtualHost>
    

        
    
            This setup will, on server start, contact
            Let's Encrypt
            to request a certificate for the domain. If Let's Encrypt can verify the ownership
            of the domain, the module will retrieve the certificate and its chain, store it
            in the local file system (see MDStoreDir)
            and provide it, on next restart, to mod_ssl.
        
    
            This happens while the server is already running. All other hosts will continue
            to work as before. While a certificate is not available, requests for the managed
            domain will be answered with a '503 Service Unavailable'. 
        
    
        
    

        
    Prerequisites
    
        
    
            This module requires mod_watchdog to be loaded as well.
        
    
            Certificate sign-up and renewal with Let's Encrypt requires your server to be
            reachable on port 80 (http:) and/or port 443 (https:) from the public internet.
            (Unless your server is configured to use DNS for challenges - more on that under
             'wildcard certificates')  
        
    
            The module will select from the methods offered by Let's Encrypt. Usually LE offers
            challenges on both ports and DNS and Apache chooses a method available.
        
    
            To determine which one is available, the module looks at the ports
            Apache httpd listens on. If those include port 80, it assumes that the
            http: challenge (named http-01) is available. If the server listens
            on port 443, the https: challenge (named tls-alpn-01) is also added to
            the list. (And if MDChallengeDns01 
            is configured, the challenge dns-01 is added as well.) 
        
    
            If your setup is not so straight forward, there are two methods available
            to influence this. First, look at MDPortMap
            if the server is behind a portmapper, such as a firewall. Second, you may
            override the module's guesswork completely by configuring
            MDCAChallenges directly.  
        
    
        
    

        
    https: Challenges
    
        
    
            For domain verification via the TLS protocol `tls-alpn-01` is the name
            of the challenge type. It requires the Apache server to listen on port 443
            (see MDPortMap if you map that port
            to something else).
        
    
            Let's Encrypt will open a TLS connection to Apache using the special indicator
            `acme-tls/1` (this indication part of TLS is called ALPN, therefore the name
            of the challenge. ALPN is also used by browsers to request a HTTP/2 connection).
        
    
            As with the HTTP/2 protocol, to allow this, you configure:
        
    
        
    Protocols h2 http/1.1 acme-tls/1
    

        
    
            And the `tls-alpn-01` challenge type is available.
	
    
        
    

        
    Wildcard Certificates
    
        
    
            Wildcard certificates are possible, but not straight-forward to use out of
            the box. Let's Encrypt requires the `dns-01` challenge verification 
            for those. No other is considered good enough.
        
    
            The difficulty here is that Apache cannot do that on its own. As the name implies, `dns-01` 
            requires you to show some specific DNS records for your domain that contain 
            some challenge data. So you need to _write_ your domain's DNS records.
        
    
            If you know how to do that, you can integrated this with mod_md. Let's 
            say you have a script for that in `/usr/bin/acme-setup-dns` you configure 
            Apache with:
        
    
        
    MDChallengeDns01 /usr/bin/acme-setup-dns
    

        
    
            and Apache will call this script when it needs to setup/teardown a DNS challenge 
            record for a domain. 
        
    
            Assuming you want a certificate for `*.mydomain.com`, mod_md will call:
        
    
        
    /usr/bin/acme-setup-dns setup mydomain.com challenge-data
# this needs to remove all existing DNS TXT records for 
# _acme-challenge.mydomain.com and create a new one with 
# content "challenge-data"
    

        
    
            and afterwards it will call
        
    
        
    /usr/bin/acme-setup-dns teardown mydomain.com
# this needs to remove all existing DNS TXT records for 
# _acme-challenge.mydomain.com
    

        
    

        
    Monitoring
    
            
    
                Apache has a standard module for monitoring: mod_status.
                mod_md contributes a section and makes monitoring your 
                domains easy.
            
    
                You see all your MDs listed alphabetically, the domain names they contain, 
                an overall status, expiration times and specific settings. The settings 
                show your selection of renewal times (or the default), the CA that is used, 
                etc.
            
    
                The 'Renewal' column will show activity and error descriptions for certificate 
                renewals. This should make life easier for people to find out if everything 
                is all right or what went wrong.
            
    
                If there is an error with an MD it will be shown here as well. This let's 
                you assess problems without digging through your server logs.
            
    
                There is also a new 'md-status' handler available to give you the MD information 
                from 'server-status' in JSON format. You configure it as
            
    
            
    <Location "/md-status">
  SetHandler md-status

                on your server. As with 'server-status' you will want to add 
                authorization for this. 
            
    
                If you just want to check the JSON status of a specific domain, simply append 
                that to your status url:
            
    
            
    > curl https://<yourhost>/md-status/another-domain.org
{
  "name": "another-domain.org",
  "domains": [
    "another-domain.org",
    "www.another-domain.org"
  ],
  ...
    

            
    
                This JSON status also shows a log of activities when domains are renewed:
            
    
            
    {
"when": "Wed, 19 Jun 2019 14:45:58 GMT",
"type": "progress", "detail": "The certificate for the managed domain has been renewed successfully and can be used. A graceful server restart now is recommended."
},{
"when": "Wed, 19 Jun 2019 14:45:58 GMT",
"type": "progress", "detail": "Retrieving certificate chain for test-901-003-1560955549.org"
},{
"when": "Wed, 19 Jun 2019 14:45:58 GMT",
"type": "progress", "detail": "Waiting for finalized order to become valid"
},{
"when": "Wed, 19 Jun 2019 14:45:50 GMT",
"type": "progress", "detail": "Submitting CSR to CA for test-901-003-1560955549.org"
},
...
    

            
    
                You will also find this information in the file `job.json` in your staging and, 
                when activated, domains directory. This allows you to inspect these at
                any later point in time as well. 
            
    
                In addition, there is MDCertificateStatus which
                gives access to relevant certificate information in JSON format.
            
    
        
    

        
    Stapling
    
            
    
                If you want to try the stapling in one Managed Domain alone at first,
                configure:
            
    
            
    <MDomain mydomain.net>
  MDStapling on
</MDomain>
    

            
    
                and use the 'server-status' and/or MDMessageCmd to see how it operates. You will
                see if Stapling information is there, how long it is valid, from where it came and
                when it will be refreshed.
            
    
                If this all works to your satisfaction, you can switch it on for all your
                certificates or just your managed ones.
            
    
                The existing stapling implementation by mod_ssl is used by many sites
                for years. There are two main differences between the mod_ssl and mod_md
                one:
            
    
            
      
                
    1. On demand vs. scheduled: mod_ssl retrieves the stapling information
                when it is requested, e.g. on a new connection. mod_md retrieves it
                right at server start and after 2/3rds of its lifetime.
      2. 
                
    2. In memory vs. persisted: mod_ssl can persist this
                information, but most example configurations use a memory cache. mod_md
                always stores in the file system.
      3. 
            
    
            
    
                If you are unlucky and restart your server during an outage of your CA's
                OCSP service, your users may no longer reach your sites. Without persistence
                your server cannot provide the client with the data and the client browser
                cannot get it as well, since the OCSP service is not responding. 
            
    
                The implementation in mod_md will have peristed it, load it again after
                restart and have it available for incoming connections. A day or two before
                this information expires, it will renew it, making it able to copy with
                a long OCSP service downtime.
            
    
                Due to backward compatibility, the existing implementation in mod_ssl could
                not be changed drastically. For example, mod_ssl is unable to add a dependency 
                to mod_watchdog without braking many existing installations (that do not load it).

    MDCAChallenges Directive

                Sets challenge types (in order of preference) when proving domain ownership.
                Supported by the module are the challenge methods 'tls-alpn-01', 'dns-01'  
                and 'http-01'. The module will look at the overall configuration of the server 
                to find out which methods can be used. 
            
    
                If the server listens on port 80, for example, the 'http-01' method is available. 
                The prerequisite for 'dns-01' is a configured  MDChallengeDns01 command. 
                'tls-alpn-01' is described above in 'https: Challenges'.
            
    
                This auto selection works for most setups. But since Apache is a very powerful 
                server with many configuration options, the situation is not clear for all 
                possible cases. For example: it may listen on multiple IP addresses where some 
                are reachable on `https:` and some not.
            
    
                If you configure MDCAChallenges directly, this auto selection is disabled. 
                Instead, the module will use the configured challenge list when talking to 
                the ACME server (a challenge type must be offered by the server as well). 
                This challenges are examined in the order specified.

                Let's Encrypt offers, right now, four such URLs. Two for
                the own legacy version of the ACME protocol, commonly named ACMEv1.
                And two for the RFC 8555 version, named ACMEv2.
            
    
                Each version has 2 endpoints, as their is a production endpoint and a
                "staging" endpoint for testing. The testing endpoint works the same, but will
                not give you certificates recognized by browsers. However, it also has
                very relaxed rate limits. This allows testing of the service repeatedly
                without you blocking yourself.

                the file holding the certificate chain for the Managed Domain. The matching
                key is specified via MDCertificateKeyFile.
            
    
            
    Example
    <MDomain mydomain.com>

                This is that equivalent of the mod_ssl 
                SSLCertificateFile directive. It 
                has several uses. 
            
    
                If you want to migrate an existing domain, using static files, to
                automated Let's Encrypt certificates, for one. You define the
                MDomainSet, add the files here and remove
                the SSLCertificateFile from
                your VirtualHosts. 
            
    
                This will give you the same as before, with maybe less repeating lines
                in your configuration. Then you can add MDRenewMode
                'always' to it and the module will get a new certificate before
                the one from the file expires. When it has done so, you remove the
                MDCertificateFile and reload the server.
            
    
                Another use case is that you renew your Let's Encrypt certificates with
                another ACME clients, for example the excellent 
                certbot. Then let your MDs point
                to the files from certbot and have both working together.

                page for easy checking of a certificate monitor. The SHA256 fingerprint 
                of the certificate is appended to the configured url.
            
    
                Certificate Monitors offer supervision of Certificate Transparency (CT) 
                Logs to track the use of certificates for domains. The least you may see 
                is that Let's Encrypt (or whichever CA you have configured) has entered 
                your certificates into the CTLogs.
            
    
                Caveat: certificate logs update and monitor's intakes of those
                updates suffer some delay. This varies between logs and monitors. A
                brand new certificate will not be known immediately.

                'hmac' value.
            
    
            
    
                You can configure those globally or for a specific MDomain. Since
                these values allow anyone to register under the same account, it is
                adivsable to give the configuration file restricted permissions,
                e.g. root only.
            
    
            
    
                The value can also be taken from a JSON file, to keep more open
                permissions on the server configuration and restrict the ones on that
                file. The JSON itself is:
            
    
            
    EAB JSON Example file
    {"kid": "kid-1", "hmac": "zWND..."}
    

    
            
    
                If you change EAB values, the new ones will be used when the next
                certificate renewal is due.

                This command gets called when one of the following events happen for
                a Managed Domain: "renewed", "installed", "expiring", "errored". The command may
                be invoked for more than these in the future and ignore events
                it is not prepared to handle.
            
    
                This is the more flexible companion to MDNotifyCmd.
            
    
            
    Example
    MDMessageCmd /etc/apache/md-message
    

    

# will be invoked when a new certificate for mydomain.org is available as:
/etc/apache/md-message renewed mydomain.com
            
    
            
    
                The program should not block, as the module will wait for it to finish. A
                return code other than 0 is regarded as an error. 
            
    
                'errored' is no immediate cause for concern since renewal is attempted
                early enough to allow the internet to come back. This is reported at most
                once per hour. 
            
    
                'expiring' should be taken serious. It is issued when the
                MDWarnWindow is reached. By default this is
                10% of the certificate lifetime, so for Let's Encrypt this currently
                means 9 days before it expires. The warning is repeated at most once
                a day. 
            
    
                'renewed' means that a new certificate has been obtained and is stored
                in the 'staging' area in the MD store. It will be activated on the next
                server restart/reload.
            
    
                'installed' is triggered when a new certificate has been transferred from
                staging into the domains location in MD store. This happens at server
                startup/reload. Different to all other invocations, MDMessageCmd is run
                with root permissions (on *nix systems) and has access to the certificate
                files (and keys). Certificates needed for other applications or
                in different formats can be processed on this event.
            
    
                'renewing' event is triggered before starting renew process for the managed
                 domain. Should the command return != 0 for this reason, renew will be
                 aborted and repeated on next cycle. Some cluster setups use this to
                 allow renewals to run only on a single node.
            
    
                'challenge-setup:type:domain' event is triggered when the challenge data for a domain has
                been created. This is invoked before the ACME server is told to check for it.
                The type is one of the ACME challenge types. This is invoked for every
                DNS name in a MDomain. Cluster setups may use this event to distribute
                challenge files to all nodes in a cluster.
            
    
                ocsp-errored happens when MDStapling is enabled for a domain, this indicates
                that an error was encountered retrieving the OCSP response from the
                Certificate Authority. mod_md will continue trying.

                All the names in the list are managed as one Managed Domain (MD). 
                mod_md will request one single certificate that is valid for all these names. This
                directive uses the global settings (see other MD directives below). If you
                need specific settings for one MD, use
                the <MDomainSet>.
            
    
                There are 2 additional settings that are necessary for a Managed Domain:
                a contact Email address (via MDContactEmail or ServerAdmin)
                and MDCertificateAgreement.
                The mail address of ServerAdmin
                is used to register at the CA (Let's Encrypt by default).
                The CA may use it to notify you about
                changes in its service or status of your certificates.
            
    
                The second setting, MDCertificateAgreement, 
                should have the value "accepted". By specifying this, you confirm that your
                accept the Terms of Service of the CA. 
            
    
            
    Example
    MDContactEmail admin@example.org
MDCertificateAgreement accepted
MDomain example.org www.example.org

<VirtualHost *:443>
    ServerName example.org
    DocumentRoot htdocs/root

    SSLEngine on
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.org
    DocumentRoot htdocs/www

    SSLEngine on
</VirtualHost>
    

    
            
    
                There are two special names that you may use in this directive: 'manual'
                and 'auto'. This determines if a Managed Domain shall have exactly the 
                name list as is configured ('manual') or offer more convenience. With 'auto'
                all names of a virtual host are added to a MD. Conveniently, 'auto' is also
                the default.
            
    
            
    Example
    MDomain example.org

<VirtualHost *:443>
    ServerName example.org
    ServerAlias www.example.org
    DocumentRoot htdocs/root

    SSLEngine on
</VirtualHost>

MDomain example2.org auto

<VirtualHost *:443>
    ServerName example2.org
    ServerAlias www.example2.org
    ...
</VirtualHost>
    

    
            
    
                In this example, the domain 'www.example.org' is automatically added to
                the MD 'example.org'. Similarly for 'example2.org' where 'auto' is configured
                explicitly. Whenever you add more ServerAlias names to this
                virtual host, they will be added as well to the Managed Domain.
            
    
                If you prefer to explicitly declare all the domain names, use 'manual' mode. 
                An error will be logged if the names do not match with the expected ones.

                with the added possibility to add setting just for this MD. In fact,
                you may also use "<MDomain ..>" as a shortcut.
            
    
            
    
                This allows you to configure an MD that uses another Certificate Authority,
                have other renewal requirements, etc.

            A common use case is to configure https: requirements separately for
            your domains.

    Module:mod_md
    

    
            
    
                The ACME protocol provides two methods to verify domain ownership via
                HTTP: one that uses 'http:' urls (port 80) and one for 'https:' urls
                (port 443). If your server is not reachable by at least one
                of the two, ACME may only work by configuring your DNS server,
                see MDChallengeDns01.
            
    
                On most public facing servers, 'http:' arrives on port 80 and
                'https:' on port 443. The module checks the ports your Apache server
                is listening on and assumes those are available. This means that
                when your server does not listen on port 80, it assumes that
                'http:' requests from the internet will not work.
            
    
                This is a good guess, but it may be wrong. For example, your Apache
                might listen to port 80, but your firewall might block it. 'http:' 
                is only available in your intranet. So, the module will falsely assume
                that Let's Encrypt can use 'http:' challenges with your server. This 
                will then fail, because your firewall will drop those.
            
    
            
    Example
    MDPortMap http:- https:8433
    

    
            
    
                The above example shows how you can specify that 'http:' requests from 
                the internet will never arrive. In addition it says that 'https:' requests
                will arrive on local port 8433.
            
    
                This is necessary if you have port forwarding in place, your server may be
                reachable from the Internet on port 443, but the local port that httpd uses is
                another one. Your server might only listen on ports 8443 and 8000, but be reached
                on ports 443 and 80 (from the internet).

    Status:Experimental
    

    Module:mod_md
    

    
            
    
                Defines what kind of private keys are generated for a managed domain and with
                what parameters. You can have more than one private key type configured and
                the module will obtain a certificate for each key.
            
    
                For example, you may configure an RSA and an Elliptic Curve (EC) key, so
                that 2 certicates are created for a domain. On a client connection, the first
                one supported by the client will then be used.
            
    
                Since EC keys and certificates are smaller, you might want to offer
                them first for all compatible (modern) clients. This can enable
                faster handshakes. Add an RSA key type to support older clients.
            
    
            
    Example
    MDPrivateKeys secp256r1 rsa3072
    

    
            
    
                The EC types supported depend on the CA you use. For Let's encrypt
                the supported curves include 'secp256r1' and 'secp384r1'.
            
    
                Each key and certificate type is stored in its own file in the
                MD store. The key type is part of the file name with some backward
                compatible naming for RSA certificates. So you may continue sharing
                these files with other applications.
            
    
                Please note that this setting only has an effect on new keys. Any existing
                private key you have remains unaffected. Also, this only affects private keys
                generated for certificates. ACME account keys are unaffected by this.

                In the default 'auto' mode, the module will do what makes most sense
                of each Managed Domain. For a domain without any certificates, it will
                obtain them from the Certificate Authority. 
            
    
            
    
                However, if you have defined an MD that is not used by any of Apache's 
                VirtualHosts, it will not bother. And for MDs with static certificate
                files (see MDCertificateFile), 
                it assumes that you have your own source, and will not renew them either.
            
    
            
    
                You can override this default in either way. If you specify 'always',
                the module will renew certificates for an MD, regardless if the
                domains are in use or if there are static files.
            
    
            
    
                For the opposite effect, configure 'manual' and no renewal will
                be attempted.

    Module:mod_md
    

    
            
    
            If the validity of the certificate falls below duration, mod_md
            will get a new signed certificate.
            
    
            Normally, certificates are valid for around 90 days and mod_md will renew 
            them the earliest 33% of their complete lifetime before they expire (so for 
            90 days validity, 30 days before it expires). If you think this is not what 
            you need, you can specify either the exact time, as in:
            
    
            
    Example
    # 21 days before expiry
MDRenewWindow 21d 
# 30 seconds (might be close)
MDRenewWindow 30s
# 10% of the cert lifetime
MDRenewWindow 10%
    

    
            
    When in auto drive mode, the module will check every 12 hours at least 
            what the status of the managed domains is and if it needs to do something. 
            On errors, for example when the CA is unreachable, it will initially retry 
            after some seconds. Should that continue to fail, it will back off to a 
            maximum interval of hourly checks.

    MDRequireHttps Directive
    

    

    Description:Redirects http: traffic to https: for Managed Domains.
    

    Syntax:MDRequireHttps off|temporary|permanent
    

    Default:MDRequireHttps off
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_md
    

    
            
    This is a convenience directive to ease http: to https: migration of 
            your Managed Domains. With:
            
    
            
    Example
    MDRequireHttps temporary
    

    
            
    you announce that you want all traffic via http: URLs to be redirected 
            to the https: ones, for now. This is safe and you can remove this again at
            any time.
            
    
                The following has consequences: if you want client to no longer use the
             http: URLs, configure:
            
    
            
    Permanent (for at least half a year!)
    MDRequireHttps permanent
    

    
            
    This does two things:
            
    
            
      
                
    1. All request to the http: resources are redirected to the
                    same url with the https: scheme using the 301
                status code. This tells clients that this is intended to be forever and
                the should update any links they have accordingly.
                
      2. 
                
    2. All answers to https: requests will carry the header
                    Strict-Transport-Security with a life time of half a year.
                    This tells the browser that it never (for half a year) shall use http:
                    when talking to this domain name. Browsers will, after having seen this, refuse
                    to contact your unencrypted site. This prevents malicious middleware to
                    downgrade connections and listen/manipulate the traffic. Which is good. But
                    you cannot simply take it back again.
                
      3. 
            
    
            
    You can achieve the same with mod_alias and some
            Redirect configuration,
            basically. If you do it yourself, please make sure to exclude the paths 
            /.well-known/* from your redirection, otherwise mod_md 
            might have trouble signing on new certificates.
            
    
            
    If you set this globally, it applies to all managed domains. If you want 
            it for a specific domain only, use:
            
    
            
    Example
    <MDomain xxx.yyy>
  MDRequireHttps temporary
</MDomain>

                Apaches 'server-status' handler allows you configure a resource to monitor
                what is going on. This includes now a section listing all Managed Domains
                with the DNS names, renewal status, lifetimes and main properties.
            
    
                You can switch that off using this directive.

                This setting only takes effect when MDStapling is enabled. It controls 
                if mod_md should also provide stapling information for certificates 
                that are not directly controlled by it, e.g. renewed via an ACME CA.

    MDStapling Directive

    Module:mod_md
    

    Compatibility:Available in version 2.4.42 and later
    

    
            
    
                mod_md offers an implementation for providing OCSP stapling information. 
                This is an alternative to the one provided by mod_ssl. For backward 
                compatibility, this is disabled by default.
            
    
                The stapling can be switched on for all certificates on the server or 
                for an individual MDomain.
                This will replace any stapling configuration 
                in mod_ssl for these hosts. When disabled, the mod_ssl stapling 
                will do the work (if it is itself enabled, of course). This allows for
                a gradual shift over from one implementation to the other.
            
    
                The stapling of mod_md will also work for domains where the certificates 
                are not managed by this module (see MDStapleOthers for how to control this). 
                This allows use of the new stapling without using any ACME certificate 
                management.

                This time window specifies when OCSP response data used in stapling 
                shall be removed from the store again. Response information older than 
                7 days (default) is deleted on server restart/reload. This keeps the store 
                from growing when certificates are renewed/reconfigured frequently.

    MDStaplingRenewWindow Directive
    

    

    Description:Control when the stapling responses will be renewed.
    

    Syntax:MDStaplingRenewWindow duration
    

    Default:MDStaplingRenewWindow 33%
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_md
    

    Compatibility:Available in version 2.4.42 and later
    

    
            
    
                If the validity of the OCSP response used in stapling falls below duration, 
                mod_md will obtain a new OCSP response.
            
    
                The CA issuing a certificate commonly also operates the OCSP responder 
                service and determines how long its signed response about the validity 
                of a certificate are itself valid. The longer a response is valid, the longer 
                it can be cached which mean better overall performance for everyone. 
                The shorter the life time, the more rapidly certificate revocations
                spread to clients. Also, service reliability is a consideration.
            
    
                By adjusting the stapling renew window you can control parts of this yourself. 
                If you make the renew time short (e.g. a short time before the current
                information expires), you gain maximum cache time. But a service outage
                (down for maintenance, for example) will affect you. If you renew a long
                time before expiry, updates will be made more frequent, cause more load
                on the CA server infrastructure and also more coordination between
                the child processes of your server.
            
    
                The default is chosen as 33%, which means renewal is started when only 
                a third of the response lifetime is left. For a CA that issues OCSP 
                responses with lifetime of 3 days, this means 2 days of caching and 1 day 
                for renewal attempts. A service outage would have to last full 24 hours 
                to affect your domains.
            
    
                Setting an absolute renew window, like `2d` (2 days), is also possible.

    MDStoreDir Directive
    

    

    Description:Path on the local file system to store the Managed Domains data.

    Default:MDStoreDir md

                Defines where on the local file system the Managed Domain data is stored. This is
                an absolute path or interpreted relative to the server root. The default will create
                a directory 'md' in your server root.
            
    
                If you move this and have already data, be sure to move/copy the data first to
                the new location, reconfigure and then restart the server. If you reconfigure
                and restart first, the server will try to get new certificates that it thinks
                are missing.

                how you can specify the time.
            
    
                The modules checks the remaining lifetime of certificates and invokes
                MDMessageCmd when there is less than the warn
                window left. With the default, this mean 9 days for certificates from
                Let's Encrypt.
            
    
                It also applies to Managed Domains with static certificate files (
                see MDCertificateFile).

    Description:Module de stockage sur disque pour le filtre de mise en
cache HTTP.
    

    Statut:Extension
    

    Identificateur de Module:cache_disk_module
    

    Fichier Source:mod_cache_disk.c
    

    Sommaire
    

    
    mod_cache_disk implémente un gestionnaire de
    stockage sur disque pour le module mod_cache.
    

    
    Les en-têtes et corps des réponses mises en cache sont stockés
    séparément sur le disque, dans une structure de répertoires basée
    sur le condensé md5 de l'URL mise en cache.
    

    
    Plusieurs réponses au contenu négocié peuvent être stockées en
    même temps, mais la mise en cache de contenus partiels n'est pas
    supportée actuellement par ce module.
    

    
    Les mises à jour atomiques du cache pour les fichiers d'en-tête
    et de corps peuvent être effectuées sans verrouillage en
    enregistrant les numéros d'inode et de périphérique du fichier de
    corps dans le fichier d'en-tête. Ceci implique que les entrées du
    cache déplacées manuellement dans le cache seront ignorées.
    

    
    L'utilitaire htcacheclean permet de lister et
    de supprimer les URLs du cache, ou de maintenir le cache en deçà de
    certaines limites de taille et/ou de nombre d'inodes. L'utilitaire
    peut être exécuté à la demande, ou automatiquement pour assurer un
    contrôle continu des tailles des répertoires.
    

    
    Note :
    
      
    mod_cache doit être chargé avant
      mod_cache_disk pour que ce dernier puisse
      fonctionner.
    
    
    
    
    Note :
    
    
    Lorsque la plate-forme la supporte, et si elle est activée via la
    directive EnableSendfile,
    mod_cache_disk utilise la fonctionnalité sendfile
    pour servir les fichiers à partir du cache. Cependant,
    mod_cache_disk ignore la configuration de la
    directive EnableSendfile dans
    un contexte de répertoire ou de fichier .htaccess, car le module ne
    dispose pas des définitions correspondantes lorsque la requête est
    servie depuis le cache.

    Module:mod_cache_disk
    

    
    
    La directive CacheReadTime permet de
    définir le temps minimum qui doit s'écouler avant d'essayer
    d'envoyer des données au client. Pendant ce temps, les données sont
    mises en tampon avant de pouvoir être envoyées au client. Les
    performances peuvent s'en trouver améliorées lorsqu'on met en cache
    du contenu en provenance d'un mandataire inverse.
    

    
    La valeur par défaut zéro désactive cette option.
    

    
    Cette directive ne prend effet que lorsque les données sont
    enregistrées dans le cache, et non lorsque les données sont servies à
    partir du cache. Il est recommandé d'harmoniser l'utilisation de cette
    directive avec celle de la directive CacheReadSize, afin de s'assurer
    que le serveur n'effectue pas une mise en tampon excessive au cas
    où les données arriveraient plus vite que prévu.

    Module:mod_cache_disk
    

    
    
    La directive CacheRoot permet de définir
    le nom du répertoire sur disque qui contiendra les fichiers du
    cache. Si le module mod_cache_disk a été chargé ou
    compilé dans le serveur Apache, cette directive doit être
    définie. L'absence de définition de la directive
    CacheRoot provoquera une erreur de traitement
    du fichier de configuration. Les directives CacheDirLevels et CacheDirLength permettent de
    définir la structure des sous-répertoires du répertoire racine
    spécifié.

    Açıklama:Bölü çizgisiyle biten yönlendirmeleri yapar ve dizin içeriği dosyalarını sunar.
    

    Durum:Temel
    

    Modül Betimleyici:dir_module
    

    Kaynak Dosyası:mod_dir.c
    

    Özet
    

    
    Bir dizin içerik dosyası şu iki kaynaktan birinden gelebilir:
    

    
      
      
    • Kullanıcı tarafından yazılmış ve ismi genellikle
        index.html olan bir dosya. Dosya ismi DirectoryIndex yönergesi ile belirlenir.
        Bu, mod_dir modülü tarafından denetlenir.
      • 

      
    • Aksi takdirde içerik listesi sunucu tarafından üretilir. Bu,
        mod_autoindex modülü tarafından sağlanır.
      • 
    
    
    
    Bu iki işlev tamamen birbirinden ayrıdır, dolayısıyla eğer isterseniz
      kendiliğinden dizin içerik listesi üretimini tamamen iptal
      edebilirsiniz.
    

    
    Sunucu http://example.com/filanca/birdizin şeklinde bir
      istek aldığında birdizin bir dizinin ismiyse ‘bölü
      çizgisiyle biten’ bir yönlendirme söz konusudur. Dizinler URL sonuna bir
      bölü çizgisi eklenmesini gerektirir, bu bakımdan mod_dir
      modülü isteği http://example.com/filanca/birdizin/ şeklinde
      yönlendirir.

    DirectoryCheckHandler Yönergesi
    

    

    Açıklama:Başka bir eylemci yapılandırılmışsa bu modülün nasıl yanıt
  vereceğini belirler
    

    Sözdizimi:DirectoryCheckHandler On|Off
    

    Öntanımlı:DirectoryCheckHandler Off
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_dir
    

    Uyumluluk:2.4.8 ve sonrasında kullanılabilmektedir. 2.4 öncesi sürümler
  örtük olarak "DirectoryCheckHandler ON" belirtilmiş gibi
  davranır.
    

    
    
    DirectoryCheckHandler yönergesi, geçerli URL için
    başka bir eylemcinin yapılandırılmış olması durumunda,
    mod_dir modülünün index dosyaları için dizine mi
    bakacağını yoksa URL'nin sonuna bölü çizgisi mi ekleyeceğini belirler.
    Eylemciler SetHandler gibi
    yönergelerle atanabileceği gibi dizin işlemleri sırasında
    mod_rewrite gibi modüller tarafından da atanabilir.
    
    

    
    2.4 öncesi sürümlerde, bir URL için başka bir eylemcinin yapılandılmış
    olması durumunda bu modül herhangi bir eylemde bulunmaz ve sonuç olarak,
    tüm dizin için bir SetHandler belirtildiği durumda
    index dosyalarının sunulmasının yanında  mod_rewrite
    gibi modüller de ayrıca bazı çelişkili sonuçlar oluşturabilir.

    DirectoryIndex Yönergesi
    

    

    Açıklama:İstemci bir dizin istediğinde dizin içeriğini listeler.

    

    Sözdizimi:DirectoryIndex
    disabled | yerel-url [yerel-url] ...
    

    Öntanımlı:DirectoryIndex index.html
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_dir
    

    
    
    DirectoryIndex yönergesi, istemci, dizinin
      sonuna bir bölü çizgisi ekleyerek dizin içeriğinin listelenmesini
      istediğinde bakılmak üzere özkaynakları listeler.
      yerel-url, sunucu üstünde istenen dizine göreli
      bir belgenin URL’sidir; normal olarak dizin içindeki bir dosyanın
      ismidir. Çeşitli URL’ler verilebilirse de sunucu daima ilk bulduğuyla
      dönecektir. Eğer özkaynakların hiçbiri yoksa ve Indexes
      seçeneği atanmışsa sunucu dizin içeriğinden bir liste üretecektir.
    

    
    DirectoryIndex index.html
    


    
    Bu yapılandırmadan sonra yapılan bir
      http://sunucum/belgeler/ isteğine karşılık, sunucu,
      mevcutsa http://sunucum/belgeler/index.html dosyasını
      döndürecek, değilse ürettiği dizin içerik listesini gönderecektir.
    

    
    Belgelerin dizine göreli olmasının gerekmediğine dikkat ediniz.
    

    
    DirectoryIndex index.html index.txt  /cgi-bin/index.pl
    


    
    Bu örnekte ise dizin içinde ne index.html ne de
      index.txt mevcut olduğunda /cgi-bin/index.pl
      CGI betiği çalıştırılacaktır.
    

    
    disabled değeri tek başına mod_dir’in bir
      dizin listesi aramasını engeller. disabled değiştirgesi
      öncesinde ve sonrasında başka bir değiştirge hatta bir
      disabled daha olsa bile sadece bir disabled
      verilmiş gibi yorumlanır.
    
    
    Bilginize: Aynı
      bağlamdaki çok sayıda DirectoryIndex
      yönergesi bir öncekini değiştirmek yerine onun bulunduğu listeye
      eklenir:
    
    
    # 1. örnek: İçerik dosyası olarak index.html atayıp sonraki satırda buna
# index.php'yi ekleyebilirsiniz.
<Directory "/foo">
    DirectoryIndex index.html
    DirectoryIndex index.php
</Directory>

# 2. Örnek: Atamaların tet bir satırda yapıldığı bu örnek 1. örneğe denktir.
<Directory "/foo">
    DirectoryIndex index.html index.php
</Directory>

# 3. Örnek: Listeyi tamamen değiştirmek için, listeyi önce sıfırlamalısınız:
# Bu örnekte içerik dosyası olarak listede sadece index.php kalır.
<Directory "/foo">
    DirectoryIndex index.html
    DirectoryIndex disabled
    DirectoryIndex index.php
</Directory>

    DirectoryIndexRedirect Yönergesi
    

    

    Açıklama:Dizin içerik listeleri için harici bir yönlendirme yapılandırır.

    

    Sözdizimi:DirectoryIndexRedirect on | off | permanent | temp | seeother |
3xx-kodu

    

    Öntanımlı:DirectoryIndexRedirect off
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_dir
    

    Uyumluluk:Apache HTTP Sunucusunun 2.3.14 ve sonraki sürümlerinde
    kullanılabilmektedir.
    

    
    
    Öntanımlı olarak, DirectoryIndex listeyi
      istemciye şeffaf olarak seçip gönderir.
      DirectoryIndexRedirect ise harici bir
      yönlendirmeye sebep olur.
    

    
    Bunlardan biri kullanılabilir:
    
    
      
     
    • on: Dizin listesi kaynağına bir 302 yönlendirmesi
     yapılır.
      • 
     
    • off: Bir yönlendirme yapılmaz. mod_dir için eski davranış
     böyleydi.
      • 
     
    • permanent: Dizin listesi kaynağına bir 301 (kalıcı)
     yönlendirmesi yapılır.
      • 
     
    • temp: Bu on ile aynı etkiye sahiptir.
      • 
     
    • seeother: Dizin listesi kaynağına bir 303 yönlendirmesi
     ("diğerine bak" olarak da bilinir)yapılır.
      • 
     
    • 3xx-code: 3xx kodu ile seçilen yönlendirme yapılır.
      • 
    
    

    
    Örnek
    DirectoryIndexRedirect on
    

    

    
    http://example.com/docs/ için yapılan bir istek, http://example.com/docs/index.html (mevcutsa) adresine geçici bir
      yönlendirme döndürür.

    DirectorySlash Yönergesi
    

    

    Açıklama:Bölü çizgisi ile biten yönlendirmeleri açar/kapar.
    

    Sözdizimi:DirectorySlash On|Off
    

    Öntanımlı:DirectorySlash On
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_dir
    

    
    
    DirectorySlash yönergesi, bir dizin isteğinde
      bulunan URL’lerin sonuna mod_dir modülü tarafından bir
      bölü çizgisi eklenip eklenmeyeceğini belirler.
    

    
    Normalde, bir kullanıcı sona bir bölü çizgisi eklemeden bir dizin için
      istekte bulunursa mod_dir zaten onu aynı özkaynağa
      yönlendirir, fakat isteğin sonuna bir bölü çizgisi eklenmesinin bazı iyi
      sebepleri vardır:
    

    
      
    
    • Kullanıcı bunun sonucunda meşru bir URL ile istekte bulunmuş olur.
      • 
    
    • mod_autoindex gerektiği gibi çalışır. Yoksa
      bağlantıdaki yolu sunamayacağından yanlış yolu gösterirdi.
      • 
    
    • DirectoryIndex yönergesi
      sadece bölü çizgisi ile biten dizin istekleri için değerlendirilir.
      • 
    
    • HTML sayfa içindeki göreli URL başvuruları gerektiği gibi
      çalışacaktır.
      • 
    
    

    
    Siz yine de bu etkiyi istemezseniz ve yukarıdaki sebepler de size uygun
      değilse yönlendirmeyi aşağıdaki gibi kapatabilirsiniz. Ancak bunu
      yaparken dikkatli olun, bununla ilgili bazı güvenlik sorunları olasılığı
      vardır.
    

    
    # Aşağıdaki güvenlik uyarısına bakınız!
    
<Location "/bir/yol">
    
  DirectorySlash Off
    
  SetHandler bir-eylemci
    
</Location>
    


    
    Güvenlik Uyarı
    
    
    Bölü çizgisi ile biten yönlendirmelerin kapatılması bir bilginin
      istemeyek açığa çıkmasına sebep olabilir. mod_autoindex
      modülünün etkin olduğunu (Options +Indexes) ve DirectoryIndex ile geçerli bir özkaynağın
      (index.html olsun) atandığını ama bu URL için başka hiçbir
      özel eylemci tanımlanmadığını varsayalım. Bu durumda bölü çizgisi ile
      biten bir istek olduğunda index.html dosyası sunulurdu.
      Fakat bölü çizgisi ile bitmeyen bir istek dizin içeriğinin
      listelenmesi ile sonuçlanırdı.
    
    
    
    
    Bir yönlendirme sözkonusu olduğunda bazı tarayıcıların yanlışlıkla POST
      isteklerini GET istekleri haline getirme (böylece POST verisi iptal olur)
      olasılığı olduğuna da dikkat edin.

    FallbackResource Yönergesi
    

    

    Açıklama:Bir dosya ile eşleşmeyen istekler için öntanımlı URL tanımlar

    

    Sözdizimi:FallbackResource disabled | yerel-url
    

    Öntanımlı:disabled - httpd 404 döndürecektir (Yok)
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_dir
    

    Uyumluluk:disabled değiştirgesi 2.4.4 sürümü ve sonrasında kullanılabilmektedir.
    

    
    
    Dosya sisteminde bulunmayan bir dosya için istek yapıldığında HTTP'nin
      404 (Yok) hatasını döndürmemesi için sunulacak dosyanın yolunu tanımlar.
      Örnek:
    

    
    FallbackResource /not-404.php
    


    
    Bu satırla, (mevcut dosyaları etkilemeden) mevcut olmayan dosyaların
      yerine not-404.php dosyası sunulacaktır.
    

    
    Belli bir dizindeki mevcut bir dosya veya betik için yapılanlar dışındaki
      tüm isteklerin tek bir dosya veya özkaynakla yerine getirilmesi sıkça istenen
      bir durum olup bu mekanizmaya 'ön denetleyici' adı verilir.
    

    
    httpd'nin önceki sürümlerinde bir dosya veya dizinin varlığının sınanması
      için genellikle mod_rewrite modülü ve -f ve
      -d kullanımı gerekirdi. Bunun için şimdi tek satırlık bir
      yapılandırma yeterli olmaktadır.
    

    
    FallbackResource /index.php
    


    
    Resim, CSS dosyaları gibi mevcut dosyalar normal olarak sunulur.
    

    
    Üst dizinden hiçbir şeyin miras alınmaması isteniyorsa bu özelliği
        kapatmak için disabled değiştirgesini kullanın.
    

    
    http://example.com/blog/ gibi bir alt URI yerel-url
      olarak sağlanır:
    

    
    <Directory "/web/example.com/htdocs/blog">
  FallbackResource /blog/index.php
</Directory>
<Directory "/web/example.com/htdocs/blog/images">
  FallbackResource disabled
</Directory>
    


    
    Bir acil durum işleyicisi (yukarıdaki durumda,
     /blog/index.php) özgün istek URL'sine sunucu değişkeni
     REQUEST_URI üzerinden erişebilir. Örneğin PHP'de bu 
     değişkene erişmek için $_SERVER['REQUEST_URI']
     kullanılır.

    Apache Module mod_authn_dbd
    

    

    Available Languages:  en  |

    Description:User authentication using an SQL database
    

    Status:Extension
    

    Module Identifier:authn_dbd_module
    

    Source File:mod_authn_dbd.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module provides authentication front-ends such as
    mod_auth_digest and mod_auth_basic
    to authenticate users by looking up users in SQL tables.
    Similar functionality is provided by, for example,
    mod_authn_file.
    
    
    This module relies on mod_dbd to specify
    the backend database driver and connection parameters, and
    manage the database connections.
    

    
    When using mod_auth_basic or
    mod_auth_digest, this module is invoked via the
    AuthBasicProvider or
    AuthDigestProvider
    with the dbd value.

    Performance and Caching
    


    Some users of DBD authentication in HTTPD 2.2/2.4 have reported that it
imposes a problematic load on the database.  This is most likely where
an HTML page contains hundreds of objects (e.g. images, scripts, etc)
each of which requires authentication.  Users affected (or concerned)
by this kind of problem should use mod_authn_socache
to cache credentials and take most of the load off the database.

    Configuration Example
    


    This simple example shows use of this module in the context of
the Authentication and DBD frameworks.
    

    # mod_dbd configuration
# UPDATED to include authentication caching
DBDriver pgsql
DBDParams "dbname=apacheauth user=apache password=xxxxxx"

DBDMin  4
DBDKeep 8
DBDMax  20
DBDExptime 300

<Directory "/usr/www/myhost/private">
  # mod_authn_core and mod_auth_basic configuration
  # for mod_authn_dbd
  AuthType Basic
  AuthName "My Server"

  # To cache credentials, put socache ahead of dbd here
  AuthBasicProvider socache dbd

  # Also required for caching: tell the cache to cache dbd lookups!
  AuthnCacheProvideFor dbd
  AuthnCacheContext my-server

  # mod_authz_core configuration
  Require valid-user

  # mod_authn_dbd SQL query to authenticate a user
  AuthDBDUserPWQuery "SELECT password FROM authn WHERE user = %s"
</Directory>
    


    top
    

    

    Exposing Login Information
    


    
If httpd was built against APR version 1.3.0
or higher, then whenever a query is made to the database server, all
column values in the first row returned by the query are placed in the
environment, using environment variables with the prefix "AUTHENTICATE_".

    

    If a database query for example returned the username, full name
and telephone number of a user, a CGI program will have access to
this information without the need to make a second independent database
query to gather this additional information.
    

    This has the potential to dramatically simplify the coding and
configuration required in some web applications.

    Module:mod_authn_dbd
    

    
    
    The AuthDBDUserPWQuery specifies an
    SQL query to look up a password for a specified user.  The user's ID
    will be passed as a single string parameter when the SQL query is
    executed.  It may be referenced within the query statement using
    a %s format specifier.
    
    
    AuthDBDUserPWQuery "SELECT password FROM authn WHERE user = %s"
    

    
    The first column value of the first row returned by the query
    statement should be a string containing the encrypted password.
    Subsequent rows will be ignored.  If no rows are returned, the user
    will not be authenticated through mod_authn_dbd.
    
    
    If httpd was built against APR version 1.3.0
    or higher, any additional column values in the first row returned by
    the query statement will be stored as environment variables with
    names of the form AUTHENTICATE_COLUMN.
    
    
    
    The encrypted password format depends on which authentication
    frontend (e.g. mod_auth_basic or
    mod_auth_digest) is being used.  See Password Formats for
    more information.

    digest authentication process.
    The user's ID and the realm, in that order, will be passed as string
    parameters when the SQL query is executed.  They may be referenced
    within the query statement using %s format specifiers.
    
    
    AuthDBDUserRealmQuery "SELECT password FROM authn WHERE user = %s AND realm = %s"
    

    
    The first column value of the first row returned by the query
    statement should be a string containing the encrypted password.
    Subsequent rows will be ignored.  If no rows are returned, the user
    will not be authenticated through mod_authn_dbd.
    
    
    If httpd was built against APR version 1.3.0
    or higher, any additional column values in the first row returned by
    the query statement will be stored as environment variables with
    names of the form AUTHENTICATE_COLUMN.
    
    
    
    The encrypted password format depends on which authentication
    frontend (e.g. mod_auth_basic or

    Apache Module mod_proxy_express
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Dynamic mass reverse proxy extension for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_express_module
    

    Source File:mod_proxy_express.c
    

    Compatibility:Available in Apache 2.3.13 and later
    

    Summary
    

    
    This module creates dynamically configured mass reverse
    proxies, by mapping the Host: header of the HTTP request to
    a server name and backend URL stored in a DBM file.
    This allows for easy use of a huge number of reverse proxies
    with no configuration changes. It is much less feature-full
    than mod_proxy_balancer, which also provides
    dynamic growth, but is intended to handle much, much
    larger numbers of backends. It is ideally suited as a
    front-end HTTP switch and for micro-services architectures.
    

    
    This module requires the service of mod_proxy.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.
    
    
    


    Limitations
    
  
      
    
    • This module is not intended to replace the dynamic capability of
      mod_proxy_balancer. Instead, it is intended to be mostly
      a lightweight and fast alternative to using mod_rewrite
      with RewriteMap and the
      [P] flag for mapped reverse proxying.
    
      • 
    
    • It does not support regex or pattern matching at all.
    
      • 
    
    • It emulates:
      
      <VirtualHost *:80>
   ServerName front.end.server
   ProxyPass        "/" "back.end.server:port"
   ProxyPassReverse "/" "back.end.server:port"
</VirtualHost>
      

      That is, the entire URL is appended to the mapped backend
      URL. This is in keeping with the intent of being a simple
      but fast reverse proxy switch.

    Apache Module mod_privileges
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Support for Solaris privileges and for running virtual hosts
under different user IDs.
    

    Status:Experimental
    

    Module Identifier:privileges_module
    

    Source File:mod_privileges.c
    

    Compatibility:Available in Apache 2.3 and up, on Solaris 10 and
OpenSolaris platforms
    

    Summary
    


    This module enables different Virtual Hosts to run with different
Unix User and Group IDs, and with different
Solaris Privileges.  In particular, it offers a solution to the
problem of privilege separation between different Virtual Hosts, first
promised by the abandoned perchild MPM.  It also offers other security
enhancements.
    


    Unlike perchild, mod_privileges
is not itself an MPM.  It works within a processing model to
set privileges and User/Group per request in a running process.
It is therefore not compatible with a threaded MPM, and will refuse
to run under one.
    


    mod_privileges raises security issues similar to
those of suexec.  But unlike suexec,
it applies not only to CGI programs but to the entire request processing
cycle, including in-process applications and subprocesses.
It is ideally suited to running PHP applications under mod_php,
which is also incompatible with threaded MPMs.  It is also well-suited
to other in-process scripting applications such as mod_perl,
mod_python, and mod_ruby, and to
applications implemented in C as apache modules where privilege
separation is an issue.
    


    


    top
    

    

    Security Considerations
    


    mod_privileges introduces new security concerns
in situations where untrusted code may be run
within the webserver process.  This applies to
untrusted modules, and scripts running under modules such as
mod_php or mod_perl.  Scripts running externally (e.g. as CGI
or in an appserver behind mod_proxy or mod_jk) are NOT affected.
    


    The basic security concerns with mod_privileges are:
    

    • Running as a system user introduces the same security issues
    as mod_suexec, and near-equivalents such as cgiwrap and suphp.
      • 

    • A privileges-aware malicious user extension (module or script)
    could escalate its privileges to anything available to the
    httpd process in any virtual host.  This introduces new risks
    if (and only if) mod_privileges is compiled with the
    BIG_SECURITY_HOLE option.
      • 

    • A privileges-aware malicious user extension (module or script)
    could escalate privileges to set its user ID to another system
    user (and/or group).
      • 

    


    The PrivilegesMode directive allows you to
select either FAST or SECURE mode.  You can
mix modes, using FAST mode for trusted users and
fully-audited code paths, while imposing SECURE mode where an
untrusted user has scope to introduce code.
    

    Before describing the modes, we should also introduce the target
use cases: Benign vs Hostile.  In a benign situation, you want to
separate users for their convenience, and protect them and the server
against the risks posed by honest mistakes, but you trust your users
are not deliberately subverting system security.  In a hostile
situation - e.g. commercial hosting - you may have users deliberately
attacking the system or each other.
    

    

    FAST mode
    

    In FAST mode, requests are run in-process with the
selected uid/gid and privileges, so the overhead is negligible.
This is suitable for benign situations, but is not secure against an
attacker escalating privileges with an in-process module or script.
    

    SECURE mode
    

    A request in SECURE mode forks a subprocess, which
then drops privileges.  This is a very similar case to running CGI
with suexec, but for the entire request cycle, and with the benefit
of fine-grained control of privileges.
    

    

    You can select different PrivilegesModes for
each virtual host, and even in a directory context within a virtual
host.  FAST mode is appropriate where the user(s) are
trusted and/or have no privilege to load in-process code.
SECURE mode is appropriate to cases where untrusted code
might be run in-process.  However, even in SECURE mode,
there is no protection against a malicious user who is able to
introduce privileges-aware code running before the start of the
request-processing cycle.

    DTracePrivileges Directive
    

    

    Description:Determines whether the privileges required by dtrace are enabled.

    Module:mod_privileges
    

    Compatibility:Available on Solaris 10 and OpenSolaris with
non-threaded MPMs (prefork or custom MPM).
    

    
    
    This server-wide directive determines whether Apache will run with
    the privileges required to run
    dtrace.
    Note that DTracePrivileges On will not in itself
    activate DTrace, but DTracePrivileges Off will prevent
    it working.
    


    

    top
    

    PrivilegesMode Directive
    

    

    Description:Trade off processing speed and efficiency vs security against
malicious privileges-aware code.
    

    Syntax:PrivilegesMode FAST|SECURE|SELECTIVE
    

    Default:PrivilegesMode FAST
    

    Context:server config, virtual host, directory
    

    Status:Experimental
    

    Module:mod_privileges
    

    Compatibility:Available on Solaris 10 and OpenSolaris with
non-threaded MPMs (prefork or custom MPM).
    

    This directive trades off performance vs security against
malicious, privileges-aware code.  In SECURE mode, each request
runs in a secure subprocess, incurring a substantial performance penalty.
In FAST mode, the server is not protected against escalation
of privileges as discussed above.
    

    This directive differs slightly between a <Directory>
	context (including equivalents such as Location/Files/If) and a
	top-level or <VirtualHost>.
    

    At top-level, it sets a default that will be inherited by virtualhosts.
	In a virtual host, FAST or SECURE mode acts on the entire
	HTTP request, and any settings in a <Directory>
	context will be ignored.  A third pseudo-mode
	SELECTIVE defers the choice of FAST vs SECURE to directives in a
	<Directory> context.
    

    In a <Directory> context, it is applicable only
	where SELECTIVE mode was set for the VirtualHost.  Only
	FAST or SECURE can be set in this context (SELECTIVE would be
meaningless).
    

    Warning
    
	Where SELECTIVE mode is selected for a virtual host, the activation
	of privileges must be deferred until after the mapping
	phase of request processing has determined what
	<Directory> context applies to the request.
	This might give an attacker opportunities to introduce
	code through a RewriteMap
	running at top-level or <VirtualHost> context
	before privileges have been dropped and userid/gid set.

    Determines whether the virtual host is allowed to run fork and exec,
    the privileges required to run subprocesses.  If this is set to
    Off the virtualhost is denied the privileges and will not
    be able to run traditional CGI programs or scripts under the traditional
    mod_cgi, nor similar external programs such as those
    created by mod_ext_filter or
    RewriteMap prog.
    Note that it does not prevent CGI programs running under alternative
    process and security models such as mod_fcgid, which is a recommended solution in Solaris.
    
    
    If set to On or Secure, the virtual host
    is permitted to run external programs and scripts as above.
    Setting VHostCGIMode Secure has
    the effect of denying privileges to the subprocesses, as described

    VHostCGIPrivs can be used to assign arbitrary privileges to subprocesses created by a virtual host, as discussed
    under VHostCGIMode.  Each privilege-name
    is the name of a Solaris privilege, such as file_setid

    A privilege-name may optionally be prefixed by
    + or -, which will respectively allow or deny a privilege.
    If used with neither + nor -, all privileges otherwise assigned
    to the virtualhost will be denied.  You can use this to override
    any of the default sets and construct your own privilege set.

    Sommaire
    

    
    Le module multi-processus (MPM) event est conçu
    pour permettre le traitement d'un nombre accru de requêtes
    simultanées en déléguant certaines tâches
    aux threads d'écoute, libérant par là-même les
    threads de travail et leur permettant de traiter les nouvelles requêtes.
    

    
    Pour utiliser le MPM event, ajoutez
    --with-mpm=event aux arguments du script
    configure lorsque vous compilez le programme
    httpd.

    Relations avec le MPM Worker
    

    Le MPM event s'inspire du MPM worker qui
implémente un serveur hybride multi-processus et multi-threads. Un processus de
contrôle unique (le parent) est chargé de lancer des processus enfants. Chaque
processus enfant crée un nombre de threads serveurs défini via la directive
ThreadsPerChild, ainsi qu'un thread
d'écoute qui surveille les requêtes entrantes et les distribue aux threads de
travail pour traitement au fur et à mesure de leur arrivée.
    


    Les directives de configuration à l'exécution sont identiques à celles que
propose le MPM worker, avec l'unique addition de la directive
AsyncRequestWorkerFactor.
    


    top
    

    

    Comment tout cela fonctionne
    
    
    
    Ce module MPM tente de résoudre le "problème keep
    alive" de HTTP. Lorsqu'un client a effectué une première requête, il peut
    garder la connexion ouverte et envoyer les requêtes suivante en utilisant le
    même socket, ce qui diminue considérablement la charge qui aurait été
    induite par la création de nouvelles connexions TCP. Cependant, le
    fonctionnement du serveur HTTP Apache impose de réserver un couple processus
    enfant/thread pour attendre les données en provenance du client, ce qui
    présente certains inconvénients.     
    Pour résoudre ce problème, le MPM Event utilise un thread d'écoute dédié
    pour chaque processus pour gérer les sockets d'écoute, tous les sockets qui
    sont dans un état de connexion persistante, les sockets où les
    filtres de gestionnaire et de protocole ont fait leur travail, et ceux pour
    lesquels la seule chose restant à faire est l'envoi des données au client.
    
    

    
    Cette nouvelle architecture, en exploitant les sockets non blocants et
    les fonctionnalités des noyaux modernes mis en valeur par
    APR (comme epoll de Linux), n'a plus besoin du
    Mutex mpm-accept pour
    éviter le problème de "thundering herd".
    

    
    La directive AsyncRequestWorkerFactor permet de
    définir le nombre total de connexions qu'un bloc processus/thread peut
    gérer.
    

    
    Connexions asynchrones
    
        
    Avec les MPM précédents, les connexions asynchrones nécessitaient
	un thread de travail dédié, mais ce n'est plus le cas avec le MPM Event.
	La page d'état de mod_status montre de nouvelles
	colonnes dans la section "Async connections" :
    
        
    
            
    Writing
    
            
    Lors de l'envoi de la réponse au client, il peut arriver que le
	    tampon d'écriture TCP soit plein si la connexion est trop lente. Si
	    cela se produit, une instruction write() vers le socket
	    renvoie en général EWOULDBLOCK ou EAGAIN
	    pour que l'on puisse y écrire à nouveau après un certain temps
	    d'inactivité. Le thread de travail qui utilise le socket doit alors
	    être en mesure de récupérer la tâche en attente et la restituer au
	    thread d'écoute qui, à son tour, la réattribuera au premier thread
	    de travail disponible, lorsqu'un évènement sera généré pour le socket
	    (par exemple, "il est maintenant possible d'écrire dans le socket").
	    Veuillez vous reporter à la section à propos des limitations pour
	    plus de détails.
            
    

            
    Keep-alive
    
            
    La gestion des connexions persistantes constitue la principale
	    amélioration par rapport au MPM Worker. Lorsqu'un thread de travail
	    a terminé l'envoi d'une réponse à un client, il peut restituer la
	    gestion du socket au thread d'écoute, qui à son tour va attendre un
	    évènement en provenance du système d'exploitation comme "le socket
	    est lisible". Si une nouvelle requête arrive en provenance du
	    client, le thread d'écoute l'attribuera au premier thread de travail
	    disponible. Inversement, si le délai KeepAliveTimeout est atteint, le socket
	    sera fermé par le thread d'écoute. Les threads de travail n'ont
	    donc plus à s'occuper des sockets inactifs et ils peuvent être
	    réutilisés pour traiter d'autres requêtes.
    

            
    Closing
    
            
    Parfois, le MPM doit effectuer une fermeture progressive, c'est
	    à dire envoyer au client une erreur survenue précédemment alors que
	    ce dernier est en train de transmettre des données à httpd. Envoyer la réponse et
	    fermer immédiatement la connexion n'est pas une bonne solution car
	    le client (qui est encore en train d'envoyer le reste de la requête)
	    verrait sa connexion réinitialisée et ne pourrait pas lire la
	    réponse de httpd. La fermeture progressive est limitée dans le temps,
	    mais elle peut tout de même être assez longue, si bien qu'elle est
	    confiée à un thread de travail (y compris les procédures d'arrêt et
	    la fermeture effective du socket). A partir de la version 2.4.28,
	    c'est aussi le cas lorsque des connexions finissent par dépasser
	    leur délai d'attente (le thread d'écoute ne gère jamais les
	    connexions, si ce n'est attendre et dispatcher les évènements
	    qu'elles génèrent).
    
        
    

        
    Ces améliorations sont disponible pour les connexions HTTP ou HTTPS.
     

    

    
    Arrêt de processus en douceur et
    utilisation du scoreboard
    
        
    Ce MPM présentait dans le passé des limitations de montée en
	puissance qui
	provoquaient l'erreur suivante : "scoreboard is full, not at
	MaxRequestWorkers". La directive MaxRequestWorkers permet de limiter le
	nombre de requêtes pouvant être servies simultanément à un moment donné
	ainsi que le nombre de processus autorisés (MaxRequestWorkers / ThreadsPerChild), alors que le
	scoreboard représente l'ensemble des processus en cours d'exécution et
	l'état de leurs threads de travail. Si le scoreboard est plein
	(autrement dit si aucun des threads n'est dans un état inactif) et si le
	nombre de requêtes actives servies est inférieur à MaxRequestWorkers, cela signifie que
	certains d'entre eux bloquent les nouvelles requêtes qui pourraient être
	servies et sont en l'occurrence mises en attente (dans la limite de la
	valeur imposée par la directive ListenBacklog). La plupart du temps, ces
	threads sont bloqués dans un état d'arrêt en douceur car ils attendent
	de terminer leur travail sur une connexion TCP pour s'arrêter et ainsi libérer
	une entrée dans le scoreboard (par exemple dans le cas du traitement des
	requêtes de longue durée, des clients lents ou des connexions en
	keep-alive). Voici deux scénarios courants :
    
        
      
            
    • Pendant un graceful
	    restart, le processus parent demande à tous ses processus
	    enfants de terminer leur travail et de s'arrêter pendant qu'il
	    recharge la configuration et lance de nouveaux processus. Si les
	    processus existants continuent de s'exécuter pendant un certain
	    temps avant de s'arrêter, le scoreboard sera partiellement occupé
	    jusqu'à ce que les entrées correspondantes soient libérées.
            
      • 
            
    • Lorsque la charge du serveur diminue suffisamment pour que httpd
	    commence à stopper certains processus (par exemple pour respecter la
	    valeur de la directive MaxSpareThreads). Cette situation
	    est problèmatique car lorsque la charge augmente à nouveau, httpd va
	    essayer de lancer de nouveaux processus. Si cette situation se
	    répète, le nombre de processus peut augmenter sensiblement,
	    aboutissant à un mélange d'anciens processus tentant de s'arrêter et
	    de nouveaux processus tentant d'effectuer un travail quelconque.
            
      • 
        
    
        
    A partir de la version 2.4.24, mpm-event est plus intelligent et peut
	traiter les arrêts graceful de manière plus efficace. Voici certaines de
	ces améliorations :
    
        
      
            
    • Utilisation de toutes les entrées du scoreboard dans la limite
	    de la valeur définie par ServerLimit. Les directives
	    MaxRequestWorkers et
	    ThreadsPerChild
	    permettent de limiter le nombre de processus actifs, alors que la
	    directive ServerLimit
	    prend aussi en compte les proccessus en arrêt graceful pour
	    permettre l'utilisation d'entrées supplémentaires du scoreboard en
	    cas de besoin. L'idée consiste à utiliser ServerLimit pour indiquer à httpd
	    conbien de processus supplémentaires seront tolérés avant
	    d'atteindre les limites imposées par les ressources du système.
            
      • 
            
    • Les processus en arrêt graceful doivent fermer leurs connexions
	    en keep-alive.
      • 
            
    • Lors d'un arrêt graceful, s'il y a plus de threads de travail en
	    cours d'exécution que de connexions ouvertes pour un processus
	    donné, ces threads sont arrêtés afin de libérer les ressources plus
	    vite (ce qui peut s'avérer nécessaire pour lancer de nouveaux
	    processus).
      • 
            
    • Si le scoreboard est plein, empêche d'arrêter d'autres processus
	    en mode graceful afin de réduire la charge jusqu'à ce que tous les
	    anciens processus soient arrêtés (sinon la situation empirerait lors
	    d'une remontée en charge).
      • 
        
    
        
    Le comportement décrit dans le dernier point est bien visible via
	mod_status dans la table des connexions avec les deux
	nouvelles colonnes "Slot" et "Stopping". La première indique le PID et
	la seconde si le processus est en cours d'arrêt ou non ; l'état
	supplémentaire "Yes (old gen)" indique un processus encore en exécution
	après un redémarrage graceful.
    
    

    
    Limitations
    
        
    La gestion améliorée des connexions peut ne pas fonctionner pour
	certains filtres de connexion qui se sont déclarés eux-mêmes
	incompatibles avec le MPM Event. Dans ce cas, le MPM Event réadoptera le
	comportement du MPM worker et réservera un thread de
	travail par connexion. Notez que tous les modules inclus dans la
	distribution du serveur httpd sont compatibles avec le MPM Event.
    

        
    Une restriction similaire apparaît lorsqu'une requête utilise un
	filtre en sortie qui doit pouvoir lire et/ou modifier la totalité du
	corps de la réponse. Si la connexion avec le client se bloque pendant
	que le filtre traite les données, et si la quantité de données produites
	par le filtre est trop importante pour être stockée en mémoire, le
	thread utilisé pour la requête n'est pas libéré pendant que httpd attend
	que les données soient transmises au client.
     
        Pour illustrer ce cas de figure, nous pouvons envisager les deux
	situations suivantes : servir une ressource statique (comme un fichier
	CSS) ou servir un contenu issu d'un programme FCGI/CGI ou d'un serveur
	mandaté. La première situation est prévisible ; en effet, le MPM Event a
	une parfaite visibilité sur la fin du contenu, et il peut utiliser les
	évènements : le thread de travail qui sert la réponse peut envoyer les
	premiers octets jusqu'à ce que EWOULDBLOCK ou
	EAGAIN soit renvoyé, et déléguer le reste de la réponse au thread
	d'écoute. Ce dernier en retour attend un évènement sur le socket, et
	délègue le reste de la réponse au premier
	thread de travail disponible. Dans la deuxième situation par contre
	(FCGI/CGI/contenu mandaté), le MPM n'a pas de visibilité sur la fin de
	la réponse, et le thread de travail doit terminer sa tâche avant de
	rendre le contrôle au thread d'écoute. La seule solution consisterait
	alors à stocker la réponse en mémoire, mais ce ne serait pas l'option la
	plus sure en matière de stabilité du serveur et d'empreinte mémoire.
        
    

    

    
    Matériel d'arrière-plan
    
        
    Le modèle event a été rendu possible par l'introduction de nouvelles
	APIs dans les systèmes d'exploitation supportés :
    
        
      
            
    • epoll (Linux) 
      • 
            
    • kqueue (BSD) 
      • 
            
    • event ports (Solaris) 
      • 
        
    
        
    Avant que ces APIs soient mises à disposition, les APIs
	traditionnelles select et poll devaient être
	utilisées. Ces APIs deviennent lentes si on les utilise pour gérer de
	nombreuses connexions ou si le jeu de connexions possède un taux de
	renouvellement élevé. Les nouvelles APIs permettent de gérer beaucoup
	plus de connexions et leur performances sont meilleures lorsque le jeu
	de connexions à gérer change fréquemment. Ces APIs ont donc rendu
	possible l'écriture le MPM Event qui est mieux adapté à la situation
	HTTP typique où de nombreuses connexions sont inactives.
    

        
    Le MPM Event suppose que l'implémentation de apr_pollset
	sous-jacente est raisonnablement sure avec l'utilisation des threads
	(threadsafe). Ceci évite au MPM de devoir effectuer trop verrouillages
	de haut niveau, ou d'avoir à réveiller le thread d'écoute pour lui
	envoyer un socket keep-alive. Ceci n'est possible qu'avec KQueue et
	EPoll.
    

    
        

    top
    

    

    Prérequis
    
    
    Ce MPM dépend des opérations atomiques compare-and-swap
    d'APR pour la synchronisation des threads. Si
    vous compilez pour une plate-forme x86 et n'avez pas besoin du
    support 386, ou si vous compilez pour une plate-forme SPARC et
    n'avez pas besoin du support pre-UltraSPARC, ajoutez
    --enable-nonportable-atomics=yes aux arguments du
    script configure. Ceci permettra à APR
    d'implémenter les opérations atomiques en utilisant des instructions
    performantes indisponibles avec les processeurs plus
    anciens.
    

    
    Ce MPM ne fonctionne pas de manière optimale sur les
    plates-formes plus anciennes qui ne gèrent pas correctement les
    threads, mais ce problème est sans objet du fait du prérequis
    concernant EPoll ou KQueue.
    

    
      

      
    • Pour utiliser ce MPM sous FreeBSD, la version 5.3 ou
      supérieure de ce système est recommandée. Il est cependant
      possible d'exécuter ce MPM sous FreeBSD 5.2.1 si vous utilisez
      libkse (voir man libmap.conf).
      • 

      
    • Pour NetBSD, il est recommander d'utiliser la version 2.0 ou
      supérieure.
      • 

      
    • Pour Linux, un noyau 2.6 est recommandé. Il faut aussi
      s'assurer que votre version de glibc a été compilée
      avec le support pour EPoll.

    Statut:MPM
    

    Module:event
    

    Compatibilité:Disponible depuis la version 2.3.13
    

    
    
    Le MPM event gère certaines connexions de manière asynchrone ;
    dans ce cas, les threads traitant la requête sont alloués selon les
    besoins et pour de courtes périodes. Dans les autres cas, un
    thread est réservé par
    connexion. Ceci peut conduire à des situations où tous les threads
    sont saturés et où aucun thread n'est capable d'effectuer de
    nouvelles tâches pour les connexions asynchrones établies.
    

    
    Pour minimiser les effets de ce problème, le MPM event utilise
    deux méthodes :
    
    
      
    	
    • il limite le nombre de connexions
	    simultanées par thread en fonction du nombre de processus
	    inactifs;
      • 
	
    • si tous les processus sont occupés, il ferme des connexions
	permanentes, même si la limite de durée de la connexion n'a
	pas été atteinte. Ceci autorise les clients
	concernés à se reconnecter à un autre processus
	possèdant encore des threads disponibles.
      • 
    
    

    
    Cette directive permet de personnaliser finement la limite du
    nombre de connexions par thread. Un processus n'acceptera de
    nouvelles connexions que si le nombre actuel de connexions (sans
    compter les connexions à l'état "closing") est
    inférieur à :
    

    
    
        ThreadsPerChild +
        (AsyncRequestWorkerFactor *
        nombre de threads inactifs)
    
    

    
    Il est possible d'effectuer une estimation du nombre maximum de
    connexions simultanées pour tous les processus et pour un nombre donné moyen
    de threads de travail inactifs comme suit :
    
    


    
    
        (ThreadsPerChild +
        (AsyncRequestWorkerFactor *
        number of idle workers)) * 
        ServerLimit
    
    

    
    Exemple
    
    
    ThreadsPerChild = 10
ServerLimit = 4
AsyncRequestWorkerFactor = 2
MaxRequestWorkers = 40

idle_workers = 4 (moyenne pour tous les processus pour faire simple)

max_connections = (ThreadsPerChild + (AsyncRequestWorkerFactor * idle_workers)) * ServerLimit 
                = (10 + (2 * 4)) * 4 = 72
    

    
    

    
    Lorsque tous les threads de travail sont inactifs, le nombre maximum
    absolu de connexions simultanées peut être calculé de manière plus simple :
    

    
    
        (AsyncRequestWorkerFactor + 1) *
        MaxRequestWorkers
    
    

    
    Exemple
    
    
    ThreadsPerChild = 10 
ServerLimit = 4
MaxRequestWorkers = 40
AsyncRequestWorkerFactor = 2
    


    
    Si tous les threads de tous les processus sont inactifs, alors :
    

    
    idle_workers = 10
    


    
    Nous pouvons calculer le nombre maximum absolu de connexions simultanées
    de deux manières :
    
    
    
    max_connections = (ThreadsPerChild + (AsyncRequestWorkerFactor * idle_workers)) * ServerLimit 
                = (10 + (2 * 10)) * 4 = 120
    
max_connections = (AsyncRequestWorkerFactor + 1) * MaxRequestWorkers 
                = (2 + 1) * 40 = 120
    

    
    

    
    Le réglage de la directive
    AsyncRequestWorkerFactor nécessite de connaître le
    trafic géré par httpd pour chaque style d'utilisation spécifique ; si vous
    modifiez la valeur par défaut, vous devrez par conséquent effectuer des
    tests approfondis en vous appuyant étroitement sur les données fournies par
    mod_status.
    

    
    La directive MaxRequestWorkers se nommait
    MaxClients avant la version 2.3.13. La valeur
    ci-dessus montre que cet ancien nom ne correspondait pas à sa
    signification exacte pour le MPM event.
    

    
    La directive AsyncRequestWorkerFactor
    accepte des valeurs d'argument de type non entier, comme "1.5".

    Ce document décrit les termes utilisés pour décrire chaque module Apache.
    

    


    top
    

    

    Description
    


    Une brève description des fonctions du module.
    

    top
    

    

    Statut
    

    
    Ce terme indique le degré de rapprochement du module par rapport
    au coeur du serveur web Apache ; en d'autres termes, vous pouvez
    être amené à recompiler le serveur pour pouvoir accéder au module et
    à ses fonctionnalités. Les valeurs possibles de cet attribut sont
    :
    

    
    
      
    MPM
    

      
    Un module dont le statut est "MPM" est un module Multi-Processus. A la différence des
      autres modules, un seul module MPM peut et doit être utilisé par Apache à
      la fois. Ce type de module est responsable de la répartition et du
      traitement de base des requêtes.
    

      
    Base
    

      
    Un module dont le statut est "Base" est compilé dans le
      serveur et chargé avec ce dernier par défaut ; il est donc
      toujours disponible à moins que vous n'ayez fait en sorte de
      supprimer le module de votre configuration.
    

      
    Extension
    

      
    Un module dont le statut est "Extension" n'est pas compilé et
      chargé dans le serveur par défaut. Pour activer le module et
      accéder à ses fonctionnalités, vous devez modifier la
      configuration de la compilation du serveur et recompiler
      Apache.
    

      
    Expérimental
    

      
    Le statut "Experimental" indique que le module fait partie du
      kit Apache, mais que vous devez l'utiliser à vos risques et
      périls. Le module est documenté à des fins d'exhaustivité, et
      n'est pas obligatoirement supporté.
    

      
    Externe
    

      
    Ce statut indique que le module ("module tiers") ne fait pas
      partie de la distribution de base d'Apache. Nous ne sommes pas
      responsables de ces modules et n'en assurons pas le support.
    
    
    

    top
    

    

    Fichier source
    

    
    Il s'agit tout simplement de la liste des noms des fichiers
    source qui contiennent le code du module. C'est aussi le nom utilisé
    par la directive <IfModule>.
    

    top
    

    

    Identificateur de module
    

    
    C'est une chaîne permettant d'identifier le module à utiliser
    dans la directive LoadModule
    pour le chargement dynamique des modules. En particulier, c'est le
    nom de la variable externe de type module dans le fichier
    source.
    

    top
    

    

    Compatibilité
    

    
    Si le module ne faisait pas partie de la distribution originale
    d'Apache version 2, la version à partir de laquelle il est
    disponible est indiquée ici. En outre, si le module n'est disponible
    que sur certaines plates-formes, cela sera mentionné ici.

    Description:Illustration de l'API des modules Apache
    

    Statut:Expérimental
    

    Identificateur de Module:example_hooks_module
    

    Fichier Source:mod_example_hooks.c
    

    Sommaire
    

    
    Certains fichiers situés dans le répertoire
    modules/examples de l'arborescence de la
    distribution d'Apache sont fournis à titre d'exemples pour ceux qui
    souhaitent écrire des modules qui utilisent l'API d'Apache.
    

    
    Le fichier principal est mod_example_hooks.c, qui
    constitue une illustration exhaustive des différents mécanismes et
    syntaxes d'appels. En aucun cas un module additionnel n'aura à
    inclure des routines pour tous les appels - il n'en nécessitera au
    contraire qu'un petit nombre !
    

    
    Le module example_hooks fonctionne réellement. Si vous le chargez dans
    votre serveur, activez le gestionnaire "example-hooks-handler" dans une
    section location, et essayez d'accéder à la zone du site web
    correspondante, vous verrez s'afficher certaines sorties que le
    module example_hooks produit au cours des différents appels.
    

    


    top
    

    

    Compilation du module example_hooks
    

    
    Pour inclure le module example_hooks dans votre serveur, effectuez les
    étapes suivantes :
    

    
      
      
    1. Exécutez configure avec l'option
      --enable-example-hooks.
      2. 

      
    2. Compilez le serveur (exécutez la commande
      "make").
      3. 
    
    

    
    Pour ajouter votre propre module :
    

    
      
      
    1. cp modules/examples/mod_example_hooks.c
      modules/nouveau_module/mod_monexemple.c
      2. 

      
    2. Modifiez le fichier.
      3. 

      
    3. Créez modules/nouveau_module/config.m4.
        
        
          
      1. Ajoutez APACHE_MODPATH_INIT(nouveau_module).
        2. 
          
      2. Copiez la ligne APACHE_MODULE contenant "example_hooks" depuis
	  modules/examples/config.m4.
        3. 
          
      3. Remplacez le premier argument "example-hooks" par
	  monexemple.
        4. 
          
      4. Remplacez le second argument par une brève description de
	  votre module. Cette description sera utilisée par la commande
	  configure --help.
        5. 
          
      5. Si la compilation de votre module nécessite des drapeaux
	  de compilation C, des drapeaux d'édition de liens, ou de
	  bibliothèques supplémentaires, ajoutez les respectivement à
	  CFLAGS, LDFLAGS et LIBS. Reportez-vous aux fichiers
	  config.m4 des répertoires des autres modules pour
	  plus d'exemples.
        6. 
          
      6. Ajoutez APACHE_MODPATH_FINISH.
        7. 
        
      
      
      4. 

      
    4. Créez le fichier
      module/nouveau_module/Makefile.in.
      Si la compilation de votre module ne nécessite pas d'instructions
      particulières, ce fichier ne doit contenir que la ligne
      include $(top_srcdir)/build/special.mk.
      5. 

      
    5. Exécutez ./buildconf à la racine du répertoire.
      6. 

      
    6. Compilez le serveur après avoir exécuté la commande configure
      avec l'option --enable-monexemple.
      7. 

    
    

    top
    

    

    Utilisation du module
mod_example_hooks
    

    
    Pour activer le module example_hooks, ajoutez à votre fichier
    httpd.conf un bloc du style :
    

    <Location "/example-hooks-info">
   SetHandler example-hooks-handler
</Location>
    


    
    Vous pouvez aussi ajouter ce qui suit dans un fichier .htaccess, puis
    accéder au fichier "test.example" à partir du répertoire
    correspondant :
    


    AddHandler example-hooks-handler ".example"
    


    
    Après avoir rechargé la configuration ou redémarré votre serveur,
    vous devriez pouvoir accéder à ce fichier et voir s'afficher ce qui
    a été décrit plus haut.

    Directive Example
    

    

    Description:Directive de démonstration pour illustrer l'API des modules
Apache
    

    Syntaxe:Example
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Statut:Expérimental
    

    Module:mod_example_hooks
    

    
    
    La directive Example n'a pour fonction que
    de définir un drapeau de démonstration que le gestionnaire de
    contenu du module example_hooks va afficher. Elle ne possède aucun
    argument. Si vous naviguez vers une URL à laquelle le gestionnaire
    de contenu example_hooks s'applique, vous verrez s'afficher les routines
    du module, ainsi que l'ordre dans lequel elles ont été appelées pour
    servir le document demandé. On peut observer l'effet de cette
    directive dans la phrase "Example
    directive declared here: YES/NO".

    AuthUserFile ディレクティブは、
    ユーザ認証のためのユーザとパスワードの一覧を格納した
    テキストファイルの名前を設定します。file-path
    はユーザファイルへのパスです。
    もし絶対パスでなければ、
    ServerRoot
    からの相対パスとして扱われます。
    

    
    ユーザファイルの各行には、ユーザ名、コロン、
    暗号化したパスワードを記述します。
    同一ユーザ ID が複数回登録された時は、
    mod_authn_file
    は最初に見つかったパスワードを使用して認証します。
    

    
    バイナリ配布の一部としてインストールされるか、
    あるいは src/support にある
    htpasswd
    ユーティリティで、この HTTP 基本認証
    用パスワードファイルをメインテナンスします。
    詳細は man
    ページをご覧頂くとして、簡単には:
    

    
    初期 ID username で、Filename
    というパスワードファイルを生成します。
    次のコマンドを発行するとパスワードが要求されます:
    

    
    
      htpasswd -c Filename username
    
    

    
    パスワードファイル Filename に、username2
    を追加したり修正したりします:
    

    
    
      htpasswd Filename username2
    
    

    
    (訳注: 非常に多くのユーザを登録すると大きなファイルになりますが)
    大きなテキストファイルを検索するのは非常に効率が悪い
    ということに注意してください。そのような必要のある時は、
    AuthDBMUserFile
    を代わりに使ってください。
    

    
    HTTP ダイジェスト認証を使用する場合は、
    htpasswd
    プログラムでは不十分です。その代わりに
    htdigest
    を使用してください。ダイジェスト認証用のデータと
    基本認証用のデータを同一ファイルに混ぜて保存できない、
    ということに注意してください。
    

    
    セキュリティ
    
    
    AuthUserFile 
        は、ウェブサーバのドキュメントツリーの外側に保管するようにしてください。
        保護しようとしているディレクトリ以下には、置かないで下さい。
        そうしないと AuthUserFile は
        ダウンロードできてしまいます。

    Ce module permet de convertir une réponse en URL de type données
    RFC2397.
    
    

    
    Les URLs de type données peuvent être incluses en ligne dans les
    pages web via le module mod_include par exemple,
    afin d'éviter aux clients d'avoir à effectuer des connexions
    séparées pour éventuellement extraire un grand nombre de petites
    images. Les URLs de type données peuvent aussi être incluses dans
    des pages générées par langages de scripting tels que PHP.

    Description:Module de verrouillage générique pour
mod_dav
    

    Statut:Extension
    

    Identificateur de Module:dav_lock_module
    

    Fichier Source:mod_dav_lock.c
    

    Compatibilité:Disponible depuis la version 2.1 d'Apache
    

    Sommaire
    

    
    ce module implémente une API de verrouillage générique que tout
    fournisseur support de mod_dav peut utiliser. Son
    activation nécessite l'utilisation de mod_dav. Mais
    sans fournisseur support pour l'utiliser, il n'est d'aucun service
    et ne doit pas être chargé dans le serveur. mod_dav_svn, le module qui
    implémente le fournisseur subversion, est un exemple
    de module de support qui utilise effectivement
    mod_dav_lock.
    

    
    Notez que mod_dav_fs n'a pas besoin de
    ce module de verrouillage générique, car il utilise sa propre
    version plus spécifique.
    

    
    Pour que mod_dav_lock puisse fonctionner, il
    vous suffit de spécifier le chemin de la base de données des verrous
    à l'aide de la directive DavGenericLockDB décrite
    ci-dessous.
    

    
    Note du développeur
    
      
    Pour déterminer le pointeur de la fonction du fournisseur de
      verrouillage, vous devez utiliser l'API
      ap_lookup_provider avec les arguments
      dav-lock, generic et 0.

    Directive DavGenericLockDB
    

    

    Description:Chemin de la base de données des verrous DAV
    

    Syntaxe:DavGenericLockDB chemin fichier
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_dav_lock
    

    
    
    La directive DavLockDB permet de spécifier
    le chemin complet de la base de données des verrous, sans extension.
    Si le chemin n'est pas absolu, il sera considéré comme relatif au
    répertoire défini par la directive ServerRoot. L'implémentation de
    mod_dav_lock utilise une base de données SDBM pour
    surveiller les verrous utilisateurs.
    

    
    Exemple
    DavGenericLockDB var/DavLock
    

    

    
    Les utilisateur et groupe sous lesquels Apache s'exécute et qui
    sont respectivement définis par les directives User et Group doivent pouvoir écrire dans le
    répertoire qui contient le fichier de la base de données des
    verrous. Pour des raisons de sécurité, il est recommandé de créer un
    répertoire dédié à la base de données des verrous, plutôt que de
    modifier les permissions d'un répertoire existant. Dans l'exemple
    ci-dessus, Apache va créer des fichiers dans le répertoire
    var/, lui-même sous-répertoire du répertoire défini par
    la directive ServerRoot, avec le nom de base
    DavLock suivi d'une extension choisie par le
    serveur.

    Apache Module mod_reqtimeout

    Description:Set timeout and minimum data rate for receiving requests

    

    Status:Extension
    

    Module Identifier:reqtimeout_module
    

    Source File:mod_reqtimeout.c
    

    Compatibility:Available in Apache HTTPD 2.2.15 and later
    

    Summary
    

    
    This module provides a convenient way to set timeouts and minimum data
    rates for receiving requests. Should a timeout occur or a data rate be
    to low, the corresponding connection will be closed by the server.
    

    
    This is logged at LogLevel
    info.
    
    
    
    If needed, the LogLevel directive
    can be tweaked to explicitly log it:
    
    
    LogLevel reqtimeout:info
    


    


    top
    

    

    Examples
    

    
      
      
    1. 
        Allow for 5 seconds to complete the TLS handshake, 10 seconds to
        receive the request headers and 30 seconds for receiving the
        request body:

        
      RequestReadTimeout handshake=5 header=10 body=30
      

      
      2. 

      
    2. 
        Allow at least 10 seconds to receive the request body.
        If the client sends data, increase the timeout by 1 second for every
        1000 bytes received, with no upper limit for the timeout (except for
        the limit given indirectly by
        LimitRequestBody):

        
      RequestReadTimeout body=10,MinRate=1000
      

      
      3. 

      
    3. 
        Allow at least 10 seconds to receive the request headers.
        If the client sends data, increase the timeout by 1 second for every
        500 bytes received. But do not allow more than 30 seconds for the
        request headers:

        
      RequestReadTimeout header=10-30,MinRate=500
      

      
      4. 

      
    4. 
        Usually, a server should have both header and body timeouts configured.
        If a common configuration is used for http and https virtual hosts, the
        timeouts should not be set too low:

        
      RequestReadTimeout header=20-40,MinRate=500 body=20,MinRate=500
      

      
      5.

    RequestReadTimeout Directive
    

    

    Description:Set timeout values for completing the TLS handshake, receiving
the request headers and/or body from client.

    

    Syntax:RequestReadTimeout
[handshake=timeout[-maxtimeout][,MinRate=rate]
[header=timeout[-maxtimeout][,MinRate=rate]
[body=timeout[-maxtimeout][,MinRate=rate]

    

    Default:RequestReadTimeout handshake=0 header=20-40,MinRate=500 body=20,MinRate=500
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_reqtimeout
    

    Compatibility:Available in version 2.2.15 and later; defaulted to disabled in
version 2.3.14 and earlier. The handshake stage is available since
version 2.4.39.

    

    
    
    This directive can set various timeouts for completing the TLS handshake,
    receiving the request headers and/or the request body from the client.
    If the client fails to complete each of these stages within the configured
    time, a 408 REQUEST TIME OUT error is sent.
    

    
    For SSL virtual hosts, the handshake timeout values is the time
    needed to do the initial SSL handshake.  If the user's browser is configured to
    query certificate revocation lists and the CRL server is not reachable, the
    initial SSL handshake may take a significant time until the browser gives up
    waiting for the CRL.  Therefore the handshake timeout should take
    this possible overhead into consideration for SSL virtual hosts (if necessary).
    The body timeout values include the time needed for SSL renegotiation
    (if necessary).
    

    
    When an AcceptFilter is in use
    (usually the case on Linux and FreeBSD), the socket is not sent to the
    server process before at least one byte (or the whole request for
    httpready) is received. The handshake and header timeouts
    configured with RequestReadTimeout are only effective
    after the server process has received the socket.
    

    
    For each of the three timeout stages (handshake, header or body), there are
    three ways to specify the timeout:
    
    

    
      

    
    • Fixed timeout value:
      

    
      stage=timeout
      

    
      The time in seconds allowed for completing the whole stage (handshaking,
    reading all of the request headers or body). A value of 0 means no limit.
      
    
      • 

    
    • Disable module for a vhost:
      

    
      handshake=0 header=0 body=0
      

    
      This disables mod_reqtimeout completely (note that
    handshake=0 is the default already and could be omitted).
      
    
      • 

    
    • Timeout value that is increased when data is
    received:
      
    
      
    stage=timeout,MinRate=data_rate
    
      

    
      Same as above, but whenever data is received, the timeout value is
    increased according to the specified minimum data rate (in bytes per
    second).
      
    
      • 

    
    • Timeout value that is increased when data is received, with an
    upper bound:
      
    
      
    stage=timeout-maxtimeout,MinRate=data_rate
    
      

    
      Same as above, but the timeout will not be increased above the second
    value of the specified timeout range.

    Apache Module mod_cgi
    

    

    Available Languages:  en  |
 fr  |
 ja  |
 ko 
    

    

    Description:Execution of CGI scripts
    

    Status:Base
    

    Module Identifier:cgi_module
    

    Source File:mod_cgi.c
    

    Summary
    

    
    Any file that has the handler
    cgi-script will be treated
    as a CGI script, and run by the server, with its output being
    returned to the client. Files acquire this handler either by
    having a name containing an extension defined by the
    AddHandler directive, or by being
    in a ScriptAlias
    directory.
    

    
    For an introduction to using CGI scripts with Apache, see
    our tutorial on Dynamic Content
    With CGI.
    

    
    When using a multi-threaded MPM under unix, the module
    mod_cgid should be used in place of
    this module. At the user level, the two modules are essentially
    identical.
    

    
    For backward-compatibility, the cgi-script handler will also be activated
    for any file with the mime-type application/x-httpd-cgi. The
    use of the magic mime-type is deprecated.
    

    


    top
    

    

    CGI Environment variables
    
    
    The server will set the CGI environment variables as described
    in the CGI specification,
    with the following provisions:
    

    
    
      
    PATH_INFO
    

      
    This will not be available if the AcceptPathInfo directive is explicitly set to
      off.  The default behavior, if AcceptPathInfo is not given, is that mod_cgi will accept path info (trailing 
      /more/path/info following the script filename in the URI),
      while the core server will return a 404 NOT FOUND error for requests
      with additional path info. Omitting the AcceptPathInfo directive has the same effect as setting
      it On for mod_cgi requests.
    

      
    REMOTE_HOST
    

      
    This will only be set if HostnameLookups is set to on (it
      is off by default), and if a reverse DNS lookup of the accessing
      host's address indeed finds a host name.
    

      
    REMOTE_IDENT
    

      
    This will only be set if IdentityCheck is set to
      on and the accessing host supports the ident
      protocol. Note that the contents of this variable cannot be
      relied upon because it can easily be faked, and if there is a
      proxy between the client and the server, it is usually
      totally useless.
    

      
    REMOTE_USER
    

      
    This will only be set if the CGI script is subject to
      authentication.
    

    
    
    
    This module also leverages the core functions 
       ap_add_common_vars and 
       ap_add_cgi_vars 
       to add environment variables like:
     
       
    
           
    DOCUMENT_ROOT
    

           
    Set with the content of the related DocumentRoot directive.
    

           
    SERVER_NAME
    

           
    The fully qualified domain name related to the request.
    

           
    SERVER_ADDR
    

           
    The IP address of the Virtual Host serving the request.
    

           
    SERVER_ADMIN
    

           
    Set with the content of the related ServerAdmin directive.
    
      
    
    
    For an exhaustive list it is suggested to write a basic CGI script 
       that dumps all the environment variables passed by Apache in a convenient format.

    CGI Debugging
    
    
    Debugging CGI scripts has traditionally been difficult, mainly
    because it has not been possible to study the output (standard
    output and error) for scripts which are failing to run
    properly. These directives provide more detailed logging of errors
    when they occur.
    

    
    CGI Logfile Format
    
      
    When configured, the CGI error log logs any CGI which does not
      execute properly. Each CGI script which fails to operate causes
      several lines of information to be logged. The first two lines
      are always of the format:
    

      
    
        %% [time] request-line
    
        %% HTTP-status CGI-script-filename
      
    

      
    If the error is that CGI script cannot be run, the log file
      will contain an extra two lines:
    

      
    
        %%error
    
        error-message
      
    

      
    Alternatively, if the error is the result of the script
      returning incorrect header information (often due to a bug in
      the script), the following information is logged:
    

      
    
        %request
    
        All HTTP request headers received
    
        POST or PUT entity (if any)
    
        %response
    
        All headers output by the CGI script
    
        %stdout
    
        CGI standard output
    
        %stderr
    
        CGI standard error
    
      
    

      
    (The %stdout and %stderr parts may be missing if the script did
      not output anything on standard output or standard error).
    
    

    

    top
    

    ScriptLog Directive
    

    

    Description:Location of the CGI script error logfile
    

    Syntax:ScriptLog file-path
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_cgi, mod_cgid
    

    
    
    The ScriptLog directive sets the CGI
    script error logfile. If no ScriptLog is given,
    no error log is created. If given, any CGI errors are logged into the
    filename given as argument. If this is a relative file or path it is
    taken relative to the ServerRoot.
    
    

    
    Example
    ScriptLog logs/cgi_log
    

    

    
    This log will be opened as the user the child processes run
    as, i.e. the user specified in the main User directive. This means that
    either the directory the script log is in needs to be writable
    by that user or the file needs to be manually created and set
    to be writable by that user. If you place the script log in
    your main logs directory, do NOT change the
    directory permissions to make it writable by the user the child
    processes run as.
    

    
    Note that script logging is meant to be a debugging feature
    when writing CGI scripts, and is not meant to be activated
    continuously on running servers. It is not optimized for speed
    or efficiency, and may have security problems if used in a
    manner other than that for which it was designed.

    ScriptLogBuffer Directive
    

    

    Description:Maximum amount of PUT or POST requests that will be recorded
in the scriptlog
    

    Syntax:ScriptLogBuffer bytes
    

    Default:ScriptLogBuffer 1024
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_cgi, mod_cgid
    

    
    
    The size of any PUT or POST entity body that is logged to
    the file is limited, to prevent the log file growing too big
    too quickly if large bodies are being received. By default, up
    to 1024 bytes are logged, but this can be changed with this
    directive.
    


    

    top
    

    ScriptLogLength Directive
    

    

    Description:Size limit of the CGI script logfile
    

    Syntax:ScriptLogLength bytes
    

    Default:ScriptLogLength 10385760
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_cgi, mod_cgid
    

    
    
    ScriptLogLength can be used to limit the
    size of the CGI script logfile. Since the logfile logs a lot of
    information per CGI error (all request headers, all script output)
    it can grow to be a big file. To prevent problems due to unbounded
    growth, this directive can be used to set an maximum file-size for
    the CGI logfile. If the file exceeds this size, no more
    information will be written to it.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:基本認証
    

    ステータス:Base
    

    モジュール識別子:auth_basic_module
    

    ソースファイル:mod_auth_basic.c
    

    互換性:Apache 2.1 以降
    

    概要
    

    
    与えられたプロバイダ (訳注: 認証での照会を行う問い合わせ先)
    でユーザを検索し、HTTP 基本認証でアクセス制限できるようになります。
    HTTP ダイジェスト認証については mod_auth_digest
    で提供されます。このモジュールを使う際はこのモジュールのほかに
    mod_authn_file といった認証モジュールと、
    mod_authz_user といった承認モジュールとの両方を、
    それぞれひとつ以上組み合わせて使うことになります。

    AuthBasicAuthoritative ディレクティブ
    

    

    説明:認証と承認を、より低いレベルのモジュールに移行させるかを
設定します。
    

    構文:AuthBasicAuthoritative On|Off
    

    デフォルト:AuthBasicAuthoritative On
    

    コンテキスト:ディレクトリ, .htaccess
    

    上書き:AuthConfig
    

    ステータス:Base
    

    モジュール:mod_auth_basic
    

    
    
    通常は、AuthBasicProvider
    ディレクティブで指定した承認モジュールを順に使ってユーザを検査しようとして、
    どのプロバイダでもユーザを検査できなかった場合、アクセス拒否します。
    AuthBasicAuthoritative を Off
    と明示的に設定すると ユーザ ID がなかったり、
    ルールがなかったりする際に、認証と承認の両方について、
    プロバイダー機構で実装されていないモジュールに処理を移行させることができます。
    AuthBasicProvider
    ディレクティブで設定できないサードパーティ製のモジュールと、
    mod_auth_basic
    とを組み合わせるときにのみ必要になるでしょう。
    そのようなモジュールを使う場合、処理順序はモジュールのソースコードが
    どうなっているかによって決まり、処理順序を指定することはできません。

mod_reqtimeout - Serveur HTTP Apache Version 2.4

    Serveur HTTP Apache Version 2.4

    Module Apache mod_reqtimeout
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Définit le délai maximum et le taux minimum de transfert des
données pour la réception des requêtes

    

    Statut:Extension
    

    Identificateur de Module:reqtimeout_module
    

    Fichier Source:mod_reqtimeout.c
    

    Compatibilité:Disponible depuis la version 2.2.15 du serveur HTTP Apache
    

    Sommaire
    

    
    Ce module permet de définir aisément le délai maximum et le taux de
    transfert des données minimum pour la réception des requêtes. Si ce délai
    est dépassé ou ce taux trop faible, la connexion concernée sera fermée par
    le serveur.
    

    
    Cet évènement sera alors enregistré dans le journal au niveau de LogLevel info.
    
    
    
    Au besoin, la directive LogLevel
    peut être modifiée pour un enregistrement dans le journal plus explicite :
    
    
    LogLevel reqtimeout:info
    


    


    top
    

    

    Exemples
    

    
      
      
    1. 
	Accorde 5 secondes pour terminer la négociation TLS, 10 secondes pour la
	réception des en-têtes de la requête et 30 secondes pour la réception du
	corps :

        
      RequestReadTimeout handshake=5 header=10 body=30
      

      
      2. 

      
    2. 
        Accorde au moins 10 secondes pour la réception du corps de
	la requête. Si le client envoie des données, augmente ce délai
	d'une seconde pour chaque paquet de 1000 octets reçus, sans
	limite supérieure (sauf si une limite a été
	spécifiée via la directive LimitRequestBody) :

        
      RequestReadTimeout body=10,MinRate=1000
      

      
      3. 

      
    3. 
        Accorde au moins 10 secondes pour la réception des en-têtes de la
	requête. Si le client envoie des données, augmente ce délai
	d'une seconde pour chaque paquet de 500 octets reçus, mais
	n'alloue que 30 secondes pour les en-têtes de la requête :

        
      RequestReadTimeout header=10-30,MinRate=500
      

      
      4. 

      
    4. 
        En général, un serveur doit avoir ses délais d'en-tête et de
	corps configurés. Si les serveurs virtuels http et https
	utilisent une configuration commune, les délais ne doivent pas
	être définis trop bas :

        
      RequestReadTimeout header=20-40,MinRate=500 body=20,MinRate=500

    Syntaxe:RequestReadTimeout
[handshake=timeout[-maxtimeout][,MinRate=rate]
[header=timeout[-maxtimeout][,MinRate=MinRate]
[body=timeout[-maxtimeout][,MinRate=MinRate]

    

    Défaut:RequestReadTimeout handshake=0 header=20-40,MinRate=500 body=20,MinRate=500
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_reqtimeout
    

    Compatibilité:Disponible depuis la version 2.2.15 du serveur HTTP
Apache ; désactivée par défaut depuis la version 2.3.14. La phase de
négociation est prise en compte à partir de la version 2.4.39.
    

    
    
    Cette directive permet de définir différents timeouts pour la négociation
    TLS, la réception des en-têtes et/ou corps des requêtes en provenance du
    client. Si le client ne parvient pas à respecter ces timeouts, un code
    d'erreur 408 REQUEST TIME OUT est envoyé.
    

    
    Pour les serveurs virtuels SSL, la valeur de timeout pour la
    négociation correspond au temps nécessaire pour la négociation
    SSL initiale. Si le navigateur du client est configuré pour demander des
    listes de révocations de certificats, et si le serveur correspondant n'est
    pas disponible, le timeout avant lequel le navigateur va abandonner son
    attente de CRL au cours de la négociation SSL initiale peut être assez
    important. Par conséquent, les valeurs de timeouts pour la
    négociation doivent prendre en compte un temps supplémentaire
    pour les serveurs virtuels SSL (si nécessaire). Le timeout concernant le
    corps inclut le temps nécessaire à la renégociation SSL (si elle est
    nécessaire).
    

    
    Lorsqu'une directive AcceptFilter
    est active (ce qui est en général le cas sous Linux et FreeBSD), la socket
    n'est envoyée au processus du serveur qu'après la réception du premier octet
    (ou de l'ensemble de la requête si httpready est défini). Les
    timeouts configurés pour la négociation et les en-têtes via la directive
    RequestReadTimeout n'entrent en ligne de compte
    qu'une fois le socket reçu par le processus du serveur.
    

    
    Il existe trois méthodes pour spécifier le timeout pour chacune des trois
    phases (négociation, en-tête ou corps) :
    
    

    
      

    
    • Valeur de timeout fixe:
      

    
      phase=timeout
      

    
      Le temps en secondes alloué pour terminer l'ensemble de la phase
    (négociation, lecture de tous les en-têtes de la requête ou du corps de
    cette dernière). La valeur 0 signifie aucune limite.
      
    
      • 

    
    • Désactivation du module pour un serveur virtuel:
      

    
      handshake=0 header=0 body=0
      

    
      Avec cet exemple, le module mod_reqtimeout est
    complètement désactivé (notez que handshake=0 correspond à la
    valeur par défaut et peut donc être omis).
      
    
      • 

    
    • La valeur du timeout qui est augmentée lorsque des données
    sont reçues :
      
    
      
    phase=timeout,MinRate=débit
    
      

    
      Identique à ce qui précède, mais chaque fois que des données sont
    reçues, la valeur du timeout est augmentée en fonction du MinRate
    spécifié (en octets par seconde).
      
    
      • 

    
    • La valeur du timeout augmente lorsque des données sont
    reçues, jusqu'à une limite supérieure:
      
    
      
    phase=timeout-maxtimeout,MinRate=débit
    
      

    
      Identique à ce qui précède, mais le timeout n'augmentera pas au
    delà de la borne supérieure du timeout spécifiée.

    説明:「最後のスラッシュ」のリダイレクトと、ディレクトリの
インデックスファイルを扱う機能を提供する
    

    ステータス:Base
    

    モジュール識別子:dir_module
    

    ソースファイル:mod_dir.c
    

    概要
    

    
    ディレクトリインデックスは、次の二つのうちどちらかが利用されます:
    

    
      
      
    • 一つ目は、ユーザが作成したファイルを用いるもので、通常
      index.html というファイル名を使います。このファイル名は、
      DirectoryIndex ディレクティブで
      指定することができます。この機能は mod_dir
      モジュールで提供されます。
      • 

      
    • もう一つの方法は、
      サーバによって自動的に生成されるディレクトリリストを用いる場合です。
      この機能は、mod_autoindex
      モジュールにより提供されます。
      • 
    
    

    
    自動的なインデックス生成機能を削除 (もしくは交換)
    できるように、この二つの機能は分離されています。
    

    
    なお http://servername/foo/dirname という URL
    へのリクエストがあった際に、dirname
    というディレクトリがあれば、「最後にスラッシュをつけた形」の URL
    へのリダイレクトを送出します。
    ディレクトリへのアクセスはスラッシュで終わっている必要があり、
    mod_dir は、http://servername/foo/dirname/
    へのリダイレクトを送出することになります。

    DirectoryIndex ディレクティブ
    

    

    説明:クライアントがディレクトリをリクエストしたときに調べる
リソースのリスト
    

    構文:DirectoryIndex
    local-url [local-url] ...

    ステータス:Base
    

    モジュール:mod_dir
    

    
    
    
    クライアントが、ディレクトリ名の最後に「/」
    を指定してディレクトリインデックスを要求する場合に探すリソースのリストを
    DirectoryIndex ディレクティブで設定します。
    Local-url
    は、リクエストされたディレクトリに対応する、サーバ上のドキュメントの
    (% エンコードされた) URL で、普通はディレクトリ中のファイルの名前です。
    複数の URL が設定された場合には、最初に見つかったものを返します。
    それらが見つからず、Indexes
    オプションがセットされている場合、ディレクトリのリストを生成します。
    
    

    
    例
    
      DirectoryIndex index.html
    
    

    
    http://myserver/docs/ へのアクセスがあり、
    http://myserver/docs/index.html
    が存在すれば、この URL が返されます。
    もし存在しなければ、ディレクトリのリストが返されます。
    

    
    注: ドキュメントが同じディレクトリ内に存在するは必要ありません。
    
    

    
    
      DirectoryIndex index.html index.txt  /cgi-bin/index.pl
    
    

    
    とした場合、index.html と index.txt
    のどちらもディレクトリ内に存在しない場合、CGI スクリプト
    /cgi-bin/index.pl が実行されます。

    DirectorySlash ディレクティブ
    

    

    説明:パス末尾のスラッシュでリダイレクトするかどうかのオンオフをトグルさせる
    

    構文:DirectorySlash On|Off
    

    デフォルト:DirectorySlash On
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:Indexes
    

    ステータス:Base
    

    モジュール:mod_dir
    

    互換性:2.0.51 以降
    

    
    
    要求のあった URL がディレクトリを指すかどうかを、
    mod_dir が調整するべきかどうかを
    DirectorySlash
    ディレクティブで設定します。
    

    
    典型的には、ユーザが末尾のスラッシュ無しでリソースへのリクエストを発行し、
    そして、そのリソースがディレクトリを指していた場合、mod_dir
    は、末尾にスラッシュを付加した上で同じリソースにリダイレクトさせます。
    この挙動には幾つか理由があります:
    

    
      
    
    • ユーザは、最終的にはリソースの別名 URL をリクエストすることになる。
      • 
    
    • mod_autoindex が期待通りに動く。mod_autoindex 
    の生成するリンクはパスを出力しませんので、スラッシュがない場合は間違ったパスを
    指してしまうことになります。
      • 
    
    • DirectoryIndex は、
    末尾にスラッシュがついているリクエストについてのみ評価される。
      • 
    
    • HTML ページの相対 URL 参照が正しく動作する。
      • 
    
    

    
    とはいえ、もしこういった効果を望まない、かつ、
    上記のような理由が当てはまらない場合は、リダイレクトを次のようにしてオフにできます:
    

    
    
        # see security warning below!
    
        <Location /some/path>
    
        
            DirectorySlash Off
    
            SetHandler some-handler
    
            
        </Location>
    
    

    
    セキュリティ警告
    
    
    末尾のスラッシュでのリダイレクトをオフにすると、結果的に情報漏洩を
    招くことになるかもしれません。
    mod_autoindex が有効 (Options +Indexes) で、
    DirectoryIndex が有効なリソース (例えば
    index.html) を指していて、また、要求のあった URL に特別な
    ハンドラが設定されていない場合を考えてみてください。
    この場合末尾にスラッシュのついているリクエストに対しては index.html
    ファイルが返されます。しかしスラッシュのないリクエストに対しては、
    ディレクトリの内容一覧を返してしまいます。

    Apache Module mod_example_hooks

    Description:Illustrates the Apache module API
    

    Status:Experimental
    

    Module Identifier:example_hooks_module
    

    Source File:mod_example_hooks.c
    

    Summary
    

    
    The files in the modules/examples directory
    under the Apache distribution directory tree are provided as an
    example to those that wish to write modules that use the Apache
    API.
    

    
    The main file is mod_example_hooks.c, which
    illustrates all the different callback mechanisms and call
    syntaxes. By no means does an add-on module need to include
    routines for all of the callbacks - quite the contrary!
    

    
    The example module is an actual working module. If you link
    it into your server, enable the "example-hooks-handler" handler for a
    location, and then browse to that location, you will see a
    display of some of the tracing the example module did as the
    various callbacks were made.
    

    


    top
    

    

    Compiling the example_hooks module
    

    
    To include the example_hooks module in your server, follow the
    steps below:
    

    
      
      
    1. 
        Run configure with --enable-example-hooks
        option.
      2. 

      
    2. Make the server (run "make").
      3. 
    
    

    
    To add another module of your own:
    

    
      
      
    1. cp modules/examples/mod_example_hooks.c
      modules/new_module/mod_myexample.c
      2. 

      
    2. Modify the file.
      3. 

      
    3. Create modules/new_module/config.m4.
        
        
          
      1. Add APACHE_MODPATH_INIT(new_module).
        2. 
          
      2. Copy APACHE_MODULE line with "example_hooks" from
            modules/examples/config.m4.
        3. 
          
      3. Replace the first argument "example_hooks" with myexample.
        4. 
          
      4. Replace the second argument with brief description of your module.
            It will be used in configure --help.
        5. 
          
      5. If your module needs additional C compiler flags, linker flags or
            libraries, add them to CFLAGS, LDFLAGS and LIBS accordingly.
            See other config.m4 files in modules directory for
            examples.
        6. 
          
      6. Add APACHE_MODPATH_FINISH.
        7. 
        
      
      
      4. 

      
    4. Create module/new_module/Makefile.in.
      If your module doesn't need special build instructions,
      all you need to have in that file is
      include $(top_srcdir)/build/special.mk.
      5. 

      
    5. Run ./buildconf from the top-level directory.
      6. 

      
    6. Build the server with --enable-myexample
      7. 

    
    

    top
    

    

    Using the mod_example_hooks Module
    

    
    To activate the example_hooks module, include a block similar to
    the following in your httpd.conf file:
    

    <Location "/example-hooks-info">
   SetHandler example-hooks-handler
</Location>
    


    
    As an alternative, you can put the following into a .htaccess file
    and then request the file "test.example" from that location:
    

    AddHandler example-hooks-handler ".example"
    


    
    After reloading/restarting your server, you should be able
    to browse to this location and see the brief display mentioned
    earlier.

    Example Directive
    

    

    Description:Demonstration directive to illustrate the Apache module
API
    

    Syntax:Example
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Experimental
    

    Module:mod_example_hooks
    

    
    
    The Example directive just sets a demonstration
    flag which the example module's content handler displays. It
    takes no arguments. If you browse to an URL to which the
    example-hooks content-handler applies, you will get a display of the
    routines within the module and how and in what order they were
    called to service the document request. The effect of this
    directive one can observe under the point "Example
    directive declared here: YES/NO".

    Description:Bandwidth Rate Limiting for Clients
    

    Status:Extension
    

    Module Identifier:ratelimit_module
    

    Source File:mod_ratelimit.c
    

    Compatibility:
    rate-initial-burst available in httpd 2.4.24 and later.
    Rate limiting proxied content does not work correctly up to httpd 2.4.33.

    

    Summary
    



    Provides a filter named RATE_LIMIT to limit client bandwidth.
The throttling is applied to each HTTP response while it is transferred to the client,
and not aggregated at IP/client level.
The connection speed to be simulated is specified, in KiB/s, using the environment
variable rate-limit.
    


    Optionally, an initial amount of burst data, in KiB, may be
configured to be passed at full speed before throttling to the
specified rate limit.  This value is optional, and is set using
the environment variable rate-initial-burst.
    


    Example Configuration
    <Location "/downloads">
    SetOutputFilter RATE_LIMIT
    SetEnv rate-limit 400 
    SetEnv rate-initial-burst 512
</Location>
    

    
If the value specified for rate-limit causes integer overflow, the rate-limited will be disabled.
If the value specified for rate-limit-burst causes integer overflow, the burst will be disabled.

    概要
    

    
    mod_ext_filter では フィルタ
    の慣れ親しんだ単純なプログラミングモデルが提供されます。このモジュールを
    使えば、標準入力から読み込んで、標準出力に書き出すプログラム
    (すなわち Unix 形式のフィルタコマンド) を Apache のフィルタにすることが
    できます。このフィルタの機構は、Apache API 向けに書かれた Apache
    サーバプロセス内で実行される専用のフィルタよりもずっと遅いですが、
    以下のような利点もあります。
    

    
      
      
    • ずっとシンプルなプログラミングモデル
      • 

      
    • プログラムが標準入力から読んで標準出力に書くものである限り、
      どんなプログラム言語やスクリプト言語でも使うことができる
      • 

      
    • 既存のプログラムを変更することなく Apache のフィルタとして
      使うことができる
      • 
    
    

    
    性能の問題により実運用に適さないとしても、フィルタのプロトタイプ用の
    環境としては mod_ext_filter は使えます。

    ExtFilterDefine ディレクティブ
    

    

    説明:外部フィルタを定義
    

    構文:ExtFilterDefine filtername parameters
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:Extension
    

    モジュール:mod_ext_filter
    

    
    
    ExtFilterDefine は、実行するプログラムや
    引数など、外部フィルタの特性を定義します。
    

    
    filtername は定義するフィルタの名前を指定します。
    この名前は後で SetOutputFilter
    ディレクティブで指定できます。名前は登録されるすべてのフィルタで
    一意でなくてはなりません。現時点では、フィルタの登録 API からは
    エラーは報告されません。ですから、重複する名前を使ってしまったときでも
    ユーザにはそのことは報告されません。
    

    
    続くパラメータの順番は関係無く、それらは実行する外部コマンドと、
    他の特性を定義します。cmd= だけが必須のパラメータです。
    指定可能なパラメータは:
    

    
    
      
    cmd=cmdline
    

      
    cmd= キーワードは実行する外部コマンドを指定します。
      プログラム名の後に引数がある場合は、コマンド行は引用符で囲む
      必要があります (例えば、cmd="/bin/mypgm
      arg1 arg2" のように)。プログラムは
      シェル経由でなく、直接実行されますので、通常のシェル用の
      エスケープは必要ありません。プログラムの引数は空白で区切られます。
      プログラムの引数の一部となる必要のある空白はバックスペースでエスケープ
      できます。引数の一部になるバックスラッシュはバックスラッシュで
      エスケープする必要があります。標準の CGI 環境変数に加えて、
      環境変数 DOCUMENT_URI, DOCUMENT_PATH_INFO, and 
      QUERY_STRING_UNESCAPED がプログラムのために設定されます。
    

      
    mode=mode
    

      
    応答を処理するフィルタには mode=output (デフォルト)
      を使います。リクエストを処理するフィルタには mode=input
      を使います。mode=input は Apache 2.1 以降で利用可能です。
    

      
    intype=imt
    

      
    このパラメータはフィルタされるべきドキュメントの
      インターネットメディアタイプ (すなわち、MIME タイプ) を
      指定します。デフォルトではすべてのドキュメントがフィルタされます。
      intype= が指定されていれば、フィルタは指定されていない
      ドキュメントには適用されなくなります。
    

      
    outtype=imt
    

      
    このパラメータはフィルタされたドキュメントの
      インターネットメディアタイプ (すなわち、MIME タイプ) を
      指定します。フィルタ動作にともなってインターネットメディアタイプが
      変わる場合に有用です。デフォルトではインターネットメディアタイプは
      変更されません。
    

      
    PreservesContentLength
    

      
    PreservesContentLength キーワードはフィルタが
      content length (訳注: コンテントの長さ)
      を変更しないということを指定します。ほとんどのフィルタは
      content length を変更するため、これはデフォルトではありません。
      フィルタが長さを変えないときは、このキーワードを指定すると
      よいでしょう。
    

      
    ftype=filtertype
    

      
    このパラメータはフィルタが登録されるべきフィルタタイプの
      数値を指定します。ほとんどの場合は、デフォルトの AP_FTYPE_RESOURCE で
      十分です。フィルタがフィルタチェーンの別の場所で動作する必要がある
      場合は、このパラメータを指定する必要があります。指定可能な値は
      util_filter.h の AP_FTYPE_foo 定義を参照してください。
    

      
    disableenv=env
    

      
    設定されていた場合にフィルタを無効にするための環境変数を
      指定します。
    

      
    enableenv=env
    

      
    このパラメータはフィルタが有効になるために設定されていなければ
      ならない環境変数を指定します。

    ExtFilterOptions ディレクティブ
    

    

    説明:mod_ext_filter のオプションを設定
    

    構文:ExtFilterOptions option [option] ...
    

    デフォルト:ExtFilterOptions DebugLevel=0 NoLogStderr
    

    コンテキスト:ディレクトリ
    

    ステータス:Extension
    

    モジュール:mod_ext_filter
    

    
    
    ExtFilterOptions ディレクティブは
    mod_ext_filter の特別な処理用のオプションを
    指定します。Option には以下のどれかを指定します。
    

    
    
      
    DebugLevel=n
    

      
    
        DebugLevel で mod_ext_filter 
        の生成するデバッグメッセージのレベルを設定できます。
        デフォルトでは、デバッグメッセージは生成されません。
        これは DebugLevel=0 と設定するのと同じです。
        数字が大きくなればなるほど、より多くのデバッグメッセージが
        生成され、サーバの性能は落ちます。数値の実際の意味は
        mod_ext_filter.c の先頭近くの DBGLVL_ 定数の
        定義で説明されています。

        
    注: デバッグメッセージを Apache のエラーログに
        保存するようにするためには、core のディレクティブ 
        LogLevel 
        を使う必要があります。
    
      
    

      
    LogStderr | NoLogStderr
    

      
    LogStderr キーワードは外部フィルタプログラムにより
      標準エラー (訳注: stderr) に書かれたメッセージを
      Apache のエラーログに保存するようにします。NoLogStderr は
      逆に保存しないようにします。
    
    
    

    
    例
    
      ExtFilterOptions LogStderr DebugLevel=0
    
    

    
    この例では、フィルタの標準出力に書かれたメッセージは
    Apache のエラーログに保存されます。mod_ext_filter からは
    デバッグメッセージは生成されません。

    Ce module permet de renvoyer un corps de requête au client, après
    l'avoir fait passer par la pile de filtres en sortie. Une chaîne de
    filtres configurée de manière appropriée peut être utilisée pour
    transformer la requête en réponse. Ce module peut ainsi être utilisé
    pour transformer un filtre en sortie en service HTTP.

    プロトコルの概要
    
    
    AJP13 プロトコルはパケット指向です。
    可読なプレーンテキスト形式ではなくバイナリ形式になったのは、
    おそらくパフォーマンス上の理由によります。
    ウェブサーバはサーブレットコンテナと TCP コネクションで通信します。
    ソケット生成は重い処理なので、負荷を減らすために、サーブレットコンテナとの
    TCP 接続を維持し、複数のリクエスト・レスポンス処理サイクルに対して一つの
    コネクションを使いまわすようになっています。
    
    
    あるリクエストにコネクションが割り当てられると、その処理サイクルが
    完了するまで他のものに使われることはありません。
    つまりコネクション上では、リクエストの同時処理は行われません。
    このため、コネクション両端での実行するコードを簡潔にできる一方で、
    同時に開くコネクションは多くなっています。
    
    
    サーブレットコンテナへのコネクションを開いた後は、コネクションの状態は
    次のどれかになります:
    
    
      
    
    •  Idle 
      コネクション上で処理されているリクエストはありません。

    •  Assigned 
      コネクションはリクエストを処理中です。

    コネクションが特定のリクエストにアサインされると、基本的な情報 (例えば
    HTTP ヘッダ等) が圧縮された形 (例えば通常の文字列は整数にエンコードされます)
    で転送されます。詳細は下記の「リクエストパケットの構造」を参照してください。
    リクエストにボディが存在 (content-length > 0) すれば、
    基本的な情報の直後に別パケットで転送されます。
    
    
    この時点でおそらく、サーブレットコンテナは処理を開始できるようになります。
    ですので、次のメッセージをウェブサーバに戻して知らせられるようになります。
    
    
      
    
    • SEND_HEADERS 
      ブラウザにヘッダを送信します。
      • 
    
    • SEND_BODY_CHUNK 
      ブラウザにボディデータのチャンクを送ります。
    
      • 
    
    • GET_BODY_CHUNK 
      リクエストのデータを全て受け取り終わっていないときに、
    残っているデータを受け取ります。パケットにある定まった最大長があり、任意の
    大きさのデータがリクエストのボディとして含まれうる場合 
    (例えばファイルのアップロードの場合) に必要となります。

    基本パケット構造
    
    
    このプロトコルには XDR から受け継いだ部分が少しありますが、多くの点で
    異なります (例えば 4 バイトアライメントでないことなど) 。
    
    
    バイトオーダー: 個々のバイトのエンディアンがどうなっているかは、
    私は詳しくないのですが、リトルエンディアンになっていると思います。
    XDR 仕様でそうなっているのと、素晴らしいことに sys/socket ライブラリが
    (C で) そういう風にできているのでそうなのだと思いました。
    ソケット呼び出しの内部についてより詳しい方がいらっしゃいましたら、
    ご教授ください。
    
    
    プロトコルには 4 つのデータタイプがあります: byte, boolean, 
    integer, string です。
    
    
    
    
    Byte
    バイト一つです。
    
    
    Boolean
    
      
    バイト一つで、1 = true, 0 = false です。
      (C のように) 非零を真として扱ってしまうと、ある場合は動くかもしれませんし、
      動かないかもしれません。
    
    
    Integer
    
      
    0 から 2^16 (32768) の範囲の数字。高次の 2 バイトが
      先に格納されます。
    
    
    String
    
      
    可変長の文字列 (2^16 が長さの上限) 。長さ情報のパケット 2 バイトの後に
      文字列 (終端文字 '\0' を含む) が続く形式でエンコードされます。
      エンコードされている長さ情報は最後の '\0' をカウントしない
      ことに注意してください――これは strlen と同様です。
      これらの終端文字をスキップするために、あまり意味の無いインクリメント文
      をたくさん書かないといけないのは、
      Java の側から見ると少し紛らわしく感じられるかもしれません。
      こうなった理由はおそらく、Servlet コンテナから返される文字列を読み出す時に、
      効率よく C のコードを書けるようにする――サーブレットから返される
      文字列は \0 文字で終端されているので、C のコードではわざわざコピーをせずに、
      一つのバッファへのリファレンスを取り回すように書くことができる――
      ためだと思われます。
      '\0' 文字がない場合は、C では文字列の規則に合うようにコピーしなければ
      いけなくなってしまいます。
    
    
    

  
    パケットサイズ
    
    
    多くのコードでそうなっているのですが、パケットサイズの最大サイズは
    8 * 1024 (8K) です。パケットの実際の長さはヘッダに
    エンコードされて入っています。
    
  
  
    パケットヘッダ
    
    
    サーバからコンテナに送出されるパケットは 0x1234 で始まります。
    コンテナからサーバに送られるパケットは AB (ASCII コード A と
    ASCII コード B) で始まります。この二バイトの後に、ペイロード長が (上記の形式で) 
    続きます。このため、ペイロード長の最大値は 2^16 にできるように思えますが、
    実際にはコードでは最大値は 8K に設定されています。
    
    
    
      
    
        パケット形式 (Server->Container)
      
    
      
    
        Byte
        0
        1
        2

        データ長 (n)
        Data
      
    
    
    
    
    ほとんどのパケットで、ペイロードの最初のバイトがメッセージの型をエンコード
     しています。例外はサーバからコンテナに送られるリクエストボディパケットです
     ――これらは標準的なパケット形式 (0x1234 とパケット長)
     ですが、その後に続くプレフィックスコードがありません。

    リクエストパケット構造
    
    
    サーバからコンテナへ送られるメッセージが
    Forward Request 型の場合 :
    
    
    AJP13_FORWARD_REQUEST :=
    prefix_code      (byte) 0x02 = JK_AJP13_FORWARD_REQUEST

    request_headers は次のような構造になっています :

sc_req_header_name := 0xA0xx (integer)

    attribute_name := sc_a_name | (sc_a_req_attribute string)

attribute_value := (string)
    
    
    もっとも重要なヘッダは content-length だということに

    送るかもしれません。
    
  
  
    protocol, req_uri, remote_addr, remote_host, server_name,
  server_port, is_ssl
    
    
    これらはまさに文字通りのものです。どれも必要で、リクエストの毎回につき
    送られます。
    
  
  
    Headers
    
    
    request_headers の構造は次のようなものです :
    まずヘッダの数 num_headers がエンコードされます。
    次にヘッダ名 req_header_name / 値 req_header_value
    の組が続きます。効率のため、一般的なヘッダは整数でエンコードして転送します。
    ヘッダ名が基本ヘッダの一覧に無い場合は、通常通り (文字列として、長さ
    プレフィックス付きで) 転送されます。一般的なヘッダ 
    sc_req_header_name の一覧とそのコードは次の通りです 
    (どれも大文字小文字を区別します) :
    
    
    
      
    名前コードの値コード名
    
      
    accept0xA001SC_REQ_ACCEPT

    user-agent0xA00ESC_REQ_USER_AGENT
    
    
    
    
    これを読み込む Java のコードでは、最初の 2 バイト整数を取り込み、
    目印になるバイト '0xA0' であれば、ヘッダ名の配列の
    インデックスを使います。先頭バイトが 0xA0 でない場合は、
    先頭 2 バイトは文字列長を表す整数であると解釈し、読み込みはじめます。
    
    
    ヘッダ名の長さは 0x9999 (==0xA000 -1) 以上にならないという
    仮定の下に動いていて、少しあいまいですが合理的な挙動になっています。
    
    
    注:
    
    content-length ヘッダはとても重要です。
    存在していて非ゼロであれば、リクエストにはボディがある (例えば POST 
    リクエスト) と推測し、そのボディを取り込むために
    直後のパケットを入力ストリームから読み込みはじめます。
    
    
  
  
    属性
    
    
    ? プレフィックスで始まる属性 (例 ?context)
    は。省略可能です。それぞれ属性の型を示す 1 バイトのコードと、
    値(文字列か整数)が続きます。
    これらは順不同で送ることができます (C のコードは常に下の一覧順に
    送るようですが) 。
    オプションの属性のリストの最後には、特別な終了コードが送られます。
    コードの一覧は :

    ?ssl_key_size0x0BInteger
    
      
    are_done0xFF-request_terminator
    
    
    
    
    context と servlet_path は現在の C の
    コードではセットされていません。また、ほとんどの Java のコードでも、
    このフィールドで何が送られても無視されます (これらのコードの後に文字列が
    送られると壊れるものもあります)。
    これがバグなのか、単に未実装なのか、歴史的経緯で残っているコードなのか
    分かりませんが、コネクションの両側ともで見当たりません。
    
    
    remote_user と auth_type はおそらく
    HTTP レベルの認証を参照していて、リモートユーザのユーザ名と認証に使用した
    タイプ (例 Basic, Digest) についてやり取りします。
    
    
    query_string, ssl_cert, 
    ssl_cipher, ssl_session 
    は HTTP と HTTPS の対応する部分を参照します。
    
    
    jvm_route はスティッキーセッションのサポート――
    ロードバランスしている複数のサーバ中の特定の Tomcat インスタンスと、
    ユーザのセッションとを紐付ける機能――に使われます。
    
    
    この基本属性一覧に無いものについては、req_attribute
    コード 0x0A 経由で属性を何個でも送ることができます。
    属性の名前と値の文字列の組を、それぞれこのコードの直後に送ります。
    環境変数はこの方法で伝えられます。
    
    
    最後に属性が全て送信された後に、属性の終端を示す 0xFF 
    が送出されます。この信号は属性の一覧の終わりを示すと同時に、リクエスト
    パケットの終端をも示しています。

    Get Body Chunk
    
    
    (ボディのサイズが大きすぎて最初のパケットに収まらない場合や、
    リクエストがチャンク転送された場合などには、) コンテナはリクエストからの

    request_length 最大 (8186 (8 Kbytes - 6)) 
    の範囲で、未転送で残っているリクエストボディの大きさのデータを
    送り返します。

    ボディの最後を超えて読み込もうとした場合) 、サーバは
    ペイロード長 0 の空パケット(0x12,0x34,0x00,0x00)
    を送り返します。

    Summary
    


    
    
      This module should be used with care. You can easily create a broken
      site using mod_file_cache, so read this document
      carefully.
    
    

    
    Caching frequently requested files that change very
    infrequently is a technique for reducing server load.
    mod_file_cache provides two techniques for caching
    frequently requested static files. Through configuration
    directives, you can direct mod_file_cache to either
    open then mmap() a file, or to pre-open a file and save
    the file's open file handle. Both techniques reduce server
    load when processing requests for these files by doing part of the work
    (specifically, the file I/O) for serving the file when the
    server is started rather than during each request.
    

    
    Notice: You cannot use this for speeding up CGI programs or
    other files which are served by special content handlers. It
    can only be used for regular files which are usually served by
    the Apache core content handler.
    

    
    This module is an extension of and borrows heavily from the
    mod_mmap_static module in Apache 1.3.

    Using mod_file_cache
    

    
    mod_file_cache caches a list of statically
    configured files via MMapFile or CacheFile directives in the main server configuration.
    

    
    Not all platforms support both directives. You will receive an error
    message in the server error log if you attempt to use an
    unsupported directive. If given an unsupported directive, the
    server will start but the file will not be cached. On platforms
    that support both directives, you should experiment with both to
    see which works best for you.
    

    
    MMapFile Directive
    

      
    The MMapFile
      directive of mod_file_cache maps a list of
      statically configured files into memory through the system call
      mmap(). This system call is available on most modern
      Unix derivatives, but not on all. There are sometimes system-specific
      limits on the size and number of files that can be
      mmap()ed, experimentation is probably the easiest way
      to find out.
    

      
    This mmap()ing is done once at server start or
      restart, only. So whenever one of the mapped files changes on the
      filesystem you have to restart the server (see the Stopping and Restarting documentation).
      To reiterate that point: if the files are modified in place
      without restarting the server you may end up serving requests that
      are completely bogus. You should update files by unlinking the old
      copy and putting a new copy in place. Most tools such as
      rdist and mv do this. The reason why this
      modules doesn't take care of changes to the files is that this check
      would need an extra stat() every time which is a waste
      and against the intent of I/O reduction.
    
    

    
    CacheFile Directive
    

      
    The CacheFile
      directive of mod_file_cache opens an active
      handle or file descriptor to the file (or files)
      listed in the configuration directive and places these open file
      handles in the cache. When the file is requested, the server
      retrieves the handle from the cache and passes it to the
      sendfile() (or TransmitFile() on Windows),
      socket API.
    

      

      
    This file handle caching is done once at server start or
      restart, only. So whenever one of the cached files changes on
      the filesystem you have to restart the server (see the
      Stopping and Restarting
      documentation). To reiterate that point: if the files are
      modified in place without restarting the server you
      may end up serving requests that are completely bogus. You
      should update files by unlinking the old copy and putting a new
      copy in place. Most tools such as rdist and
      mv do this.
    
    

    
    Note
    
      
    Don't bother asking for a directive which recursively
      caches all the files in a directory. Try this instead... See the
      Include directive, and consider
      this command:
    

      
    
        find /www/htdocs -type f -print \
    
        | sed -e 's/.*/mmapfile &/' > /www/conf/mmap.conf
      
    
    
    

    

    top
    

    CacheFile Directive
    

    

    Description:Cache a list of file handles at startup time
    

    Syntax:CacheFile file-path [file-path] ...
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_file_cache
    

    
    
    The CacheFile directive opens handles to
    one or more files (given as whitespace separated arguments) and
    places these handles into the cache at server startup
    time. Handles to cached files are automatically closed on a server
    shutdown.  When the files have changed on the filesystem, the
    server should be restarted to re-cache them.
    

    
    Be careful with the file-path arguments: They have
    to literally match the filesystem path Apache's URL-to-filename
    translation handlers create. We cannot compare inodes or other
    stuff to match paths through symbolic links etc.
    because that again would cost extra stat() system
    calls which is not acceptable. This module may or may not work
    with filenames rewritten by mod_alias or
    mod_rewrite.
    

    
    Example
    CacheFile /usr/local/apache/htdocs/index.html

    MMapFile Directive
    

    

    Description:Map a list of files into memory at startup time
    

    Syntax:MMapFile file-path [file-path] ...
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_file_cache
    

    
    
    The MMapFile directive maps one or more files
    (given as whitespace separated arguments) into memory at server
    startup time. They are automatically unmapped on a server
    shutdown. When the files have changed on the filesystem at
    least a HUP or USR1 signal should be send to
    the server to re-mmap() them.
    

    
    Be careful with the file-path arguments: They have
    to literally match the filesystem path Apache's URL-to-filename
    translation handlers create. We cannot compare inodes or other

    Module Apache mod_filter

    Description:Module de configuration de filtre intelligent sensible au
contexte
    

    Statut:Base
    

    Identificateur de Module:filter_module
    

    Fichier Source:mod_filter.c
    

    Compatibilité:Versions 2.1 et supérieures
    

    Sommaire
    

    
    Ce module permet une configuration intelligente et dépendant du
    contexte des filtres de contenu en sortie. Par exemple, Apache peut
    être configuré pour faire traiter différents types de contenus par
    différents filtres, même lorsque le type de contenu n'est pas connu
    à l'avance (par exemple dans un serveur mandataire).
    

    
    Le fonctionnement de mod_filter consiste à
    introduire des branchements dans la chaîne de filtrage. Plutôt que
    d'insérer directement des filtres dans la chaîne, on insère un
    sélecteur de filtre qui va effectuer un branchement conditionnel
    vers un fournisseur de filtre. mod_filter peut
    utiliser tout filtre de contenu comme fournisseur ; aucune
    modification des modules de filtrage existants n'est nécessaire
    (bien qu'il soit tout de même possible de les simplifier).
    

    


    top
    

    

    Filtrage intelligent
    
    
    Dans le modèle de filtrage traditionnel, les filtres sont insérés
    sans condition à l'aide de la directive AddOutputFilter et des directives
    apparentées. Chaque filtre doit ensuite déterminer s'il doit
    s'exécuter ou non, et les administrateurs du serveur disposent de
    peu de souplesse pour faire en sorte que la chaîne soit traitée de
    manière dynamique.
    

    
    mod_filter, à l'opposé, fournit aux
    administrateurs du serveur un grand degré de souplesse pour
    configurer la chaîne de filtrage. Concrètement, la décision
    d'insérer un filtre peut être prise en fonction d'une expression booléenne complexe. Ceci
    généralise le fonctionnement relativement souple de la directive
    AddOutputFilterByType.

    Déclarations de filtres, fournisseurs et
chaînes
    
    
    
    [Cette image illustre le modèle de filtrage traditionnel]
    
    Figure 1: Le modèle de filtrage traditionnel
    

    
    Dans le modèle traditionnel, les filtres en sortie constituent
    une simple chaîne s'étendant depuis le générateur de contenu (ou
    gestionnaire) jusqu'au client. Ce fonctionnement peut convenir s'il
    permet d'atteindre le but recherché, mais pose
    problème lorsque cette chaîne doit être configurée dynamiquement en
    fonction de la sortie du gestionnaire.
    

    
    
    [Cette image illustre le modèle de fonctionnement de     mod_filter]
    
    Figure 2: Le modèle de fonctionnement de
    mod_filter
    

    
    Le fonctionnement de mod_filter consiste à
    introduire des branchements dans la chaîne de filtrage. Plutôt que
    d'insérer directement des filtres dans la chaîne, on insère un
    sélecteur de filtre qui va effectuer un branchement conditionnel
    vers un fournisseur de filtre. mod_filter peut
    utiliser tout filtre de contenu comme fournisseur ; aucune
    modification des modules de filtrage existants n'est nécessaire
    (bien qu'il soit tout de même possible de les simplifier). Il peut y
    avoir plusieurs fournisseurs pour un seul filtre, mais un seul
    fournisseur sera choisi pour chaque requête.
    

    
    Une chaîne de filtrage peut comporter autant d'instances du
    sélecteur de filtre que l'on souhaite, chacune d'entre elles pouvant
    disposer de plusieurs fournisseurs. Un sélecteur de filtre possédant
    un seul fournisseur dont le choix est inconditionnel constitue un
    cas particulier : cette situation est équivalente à l'insertion
    directe du filtre dans la chaîne.
    

    top
    

    

    Configuration de la chaîne de
filtrage
    
    
    Trois étapes sont nécessaires pour configurer une chaîne de
    filtrage avec mod_filter. Voir ci-dessous la
    description détaillée des directives.
    

    
    
    
    Déclaration des filtres
    
    
    La directive FilterDeclare permet de déclarer un
    filtre en lui assignant un nom et un type. Elle n'est obligatoire
    que si le filtre n'est pas du type par défaut
    AP_FTYPE_RESOURCE.
    

    
    Enregistrement des fournisseurs
    
    
    La directive FilterProvider permet d'associer un
    fournisseur à un filtre. Le filtre a été éventuellement déclaré à
    l'aide de la directive FilterDeclare ; si ce n'est pas le cas, FilterProvider
    va le déclarer implicitement avec le type par défaut
    AP_FTYPE_RESOURCE. Le fournisseur doit avoir été enregistré à
    l'aide de ap_register_output_filter par un module
    quelconque. Le dernier argument de la directive FilterProvider est une expression :
    le fournisseur s'exécutera pour une requête si et seulement si
    l'expression est évaluée vraie. L'expression peut évaluer une
    requête HTTP ou les en-têtes de la réponse, des variables
    d'environnement, ou le gestionnaire utilisé par cette requête. À la
    différence des version précédentes, mod_filter supporte désormais
    les expressions complexes associant des critères multiples au moyen
    d'une logique AND / OR (&& / ||) et de parenthèses. Pour les
    détails sur la syntaxe de l'expression, voir la documentation sur ap_expr.
    

    
    Configuration de la chaîne de filtrage
    
    
    Les directives ci-dessus permettent d'élaborer les éléments
    d'une chaîne de filtrage intelligente, mais pas de les configurer en
    vue de leur exécution. La directive FilterChain élabore une chaîne de filtrage à
    partir de filtres intelligents déclarés, permettant avec souplesse
    d'insérer des filtres au début ou à la fin de la chaîne, de
    supprimer un filtre ou même la chaîne complète.
    

    

    top
    

    

    Filtrage et statut de la réponse
    
    
    Normalement, mod_filter n'applique les filtres qu'aux réponses
    possédant un statut HTTP 200 (OK). Pour pouvoir filtrer des
    documents possédant un autre statut, vous devez définir la variable
    d'environnement filter-errordocs, les réponses étant
    alors filtrées sans se préoccuper de leur statut. Pour définir ce
    comportement de manière plus fine, vous pouvez utiliser des
    conditions dans la directive
    FilterProvider.
    

    top
    

    

    Mise à jour depuis une configuration du
serveur HTTP Apache 2.2
    
    
    La directive FilterProvider a été modifiée par
    rapport à httpd 2.2 : les arguments match et
    dispatch ont été remplacés par l'argument unique
    expression plus polyvalent. En général, il est possible
    de convertir une paire match/dispatch vers les deux côtés d'une
    expression, de la manière suivante :
    
    
    "dispatch = 'match'"
    
    
    Les en-têtes de requête et de réponse et les variables
    d'environnement sont maintenant interprétés selon les syntaxes
    respectives %{req:foo}, %{resp:foo} et
    %{env:foo}. Les variables %{HANDLER} et
    %{CONTENT_TYPE} sont également supportées.
    
    
    Notez que l'évaluation de l'expression ne supporte plus les
    comparaisons de sous-chaînes. Ces dernières peuvent
    être remplacées par des comparaisons d'expressions rationnelles.
    

    top
    

    

    Exemples
    
    
    
    
    Inclusions côté serveur (SSI)
    
    
    Un exemple simple de remplacement de la directive AddOutputFilterByType
    
    FilterDeclare SSI
FilterProvider SSI INCLUDES "%{CONTENT_TYPE} =~ m|^text/html|"
FilterChain SSI
    

    
    

    
    Inclusions côté serveur (SSI)
    
    
    Même exemple que ci-dessus, mais envoi vers un gestionnaire
    (comportement classique des SSI ; les fichiers .shtml sont
    traités).
    
    FilterProvider SSI INCLUDES "%{HANDLER} = 'server-parsed'"
FilterChain SSI
    

    
    

    
    Émulation de mod_gzip avec mod_deflate
    
    
    Insertion du filtre INFLATE seulement si l'en-tête
    Accept-Encoding a une valeur autre que "gzip". Ce filtre s'exécute
    avec le type ftype CONTENT_SET.
    
    FilterDeclare gzip CONTENT_SET
FilterProvider gzip inflate "%{req:Accept-Encoding} !~ /gzip/"
FilterChain gzip
    

    
    

    
    Diminution de la résolution d'une image
    
    
    Supposons que nous voulions réduire la résolution de toutes les
    images web, et que nous disposions de filtres pour les images GIF,
    JPEG et PNG.
    
    FilterProvider unpack jpeg_unpack "%{CONTENT_TYPE} = 'image/jpeg'"
FilterProvider unpack gif_unpack  "%{CONTENT_TYPE} = 'image/gif'"
FilterProvider unpack png_unpack  "%{CONTENT_TYPE} = 'image/png'"

FilterProvider downsample downsample_filter "%{CONTENT_TYPE} = m|^image/(jpeg|gif|png)|"
FilterProtocol downsample "change=yes"

FilterProvider repack jpeg_pack "%{CONTENT_TYPE} = 'image/jpeg'"
FilterProvider repack gif_pack  "%{CONTENT_TYPE} = 'image/gif'"
FilterProvider repack png_pack  "%{CONTENT_TYPE} = 'image/png'"
<Location "/image-filter">
    FilterChain unpack downsample repack
</Location>
    

    
    
    
    

    top
    

    

    Gestion de protocole
    
    
    Historiquement, tout filtre doit s'assurer que toute modification
    qu'il effectue est correctement représentée dans les en-têtes de la
    réponse HTTP, et qu'il ne s'exécutera pas si cette exécution
    résultait en une modification interdite. Ceci impose aux auteurs de
    filtres la corvée de réimplémenter certaines fonctionnalités
    communes dans chaque filtre :
    

    
      
    
    • De nombreux filtres modifient les contenus, et de ce fait
    invalident les balises de ces contenus, leur somme de
    contrôle, leur condensé (hash) existant, ainsi que leur
    taille.
      • 

    
    • Les filtres qui nécessitent une réponse entière et non tronquée en
    entrée, doivent s'assurer qu'il n'ont pas reçu une réponse à une
    requête partielle.
      • 

    
    • Les filtres qui modifient la sortie d'un autre filtre doivent
    s'assurer qu'ils ne violent pas la directive d'un en-tête
    Cache-Control: no-transform éventuel.
      • 

    
    • Les filtres peuvent agir sur des réponses de façon à ce qu'elles
    ne puissent plus être mises en cache.
      • 
    
    

    
    mod_filter a pour but de gérer de manière
    générale ces détails de l'implémentation des filtres, réduisant par
    là-même la complexité des modules de filtrage de contenu. Le
    travail permettant d'atteindre ce but est cependant toujours en
    cours ; la directive FilterProtocol
    implémente certaines de ces fonctionnalités à des fins de
    compatibilité ascendante avec les modules d'Apache 2.0. Pour les
    versions 2.1 et supérieures de httpd, les API
    ap_register_output_filter_protocol et
    ap_filter_protocol permettent aux modules de filtrage
    de définir leurs propres comportements.
    

    
    Cependant, mod_filter ne doit pas interférer
    avec un filtre qui gère déjà tous les aspects du protocole. Par
    défaut (c'est à dire en l'absence de toute directive FilterProtocol),
    mod_filter ne modifiera donc pas les en-têtes.
    

    
    Au moment où ces lignes sont écrites, cette fonctionnalité a été
    très peu testée, car les modules d'usage courant ont été conçus pour
    fonctionner avec httpd 2.0. Les modules qui l'utilisent devront donc
    l'expérimenter avec précautions.

    Cette directive active un filtre en sortie particulier pour une
    requête en fonction du type de média de la réponse.
    

    
    L'exemple suivant active le filtre DEFLATE qui est
    fourni par le module mod_deflate. Il va compresser
    toute sortie dont le type MIME est text/html ou
    text/plain avant de l'envoyer au client.

    Si vous voulez assigner plusieurs filtres au contenu, leurs noms
    doivent être séparés par des points-virgules. On peut aussi utiliser
    une directive AddOutputFilterByType pour
    chacun des filtres à assigner.
    

    
    La configuration ci-dessous impose le traitement de toute sortie
    de script dont le type MIME est text/html en premier
    lieu par le filtre INCLUDES, puis par le filtre
    DEFLATE.

    Cette directive permet de déclarer un filtre en sortie associé à
    un en-tête ou une variable d'environnement qui déterminera les
    conditions de son exécution. Le premier argument est le nom du
    filtre destiné à être utilisé dans les directives FilterProvider, FilterChain et FilterProtocol.
    

    
    Le dernier argument (optionnel) est le type du filtre, et peut
    prendre les valeurs de ap_filter_type, à savoir

    Cette directive permet à mod_filter de s'assurer
    qu'un filtre ne s'exécutera pas s'il ne doit pas le faire, et que
    les en-têtes de la réponse HTTP sont définis correctement en tenant
    compte des effets du filtre.
    

    
    Cette directive se présente sous deux formes. Avec trois
    arguments, elle s'applique de manière spécifique à un nom
    filtre et un nom fournisseur pour ce filtre. Avec
    deux arguments, elle s'applique à un nom filtre pour
    tout fournisseur qu'il actionne.
    

    
    Les drapeaux spécifiés sont fusionnés avec les drapeaux que les
    fournisseurs sous-jacents ont éventuellement enregistrés avec
    mod_filter. Par exemple, un filtre peut avoir
    spécifié en interne un drapeau équivalent à change=yes,
    mais une configuration particulière du module peut le surcharger
    en spécifiant change=no.
    
    

    
    drapeaux_protocole peut contenir un ou plusieurs
    drapeaux parmi les suivants :
    

    
    
    
    change=yes|no
    
    
    Indique si le filtre doit modifier le contenu, y compris éventuellement sa
    taille
    

    
    change=1:1
    
    
    Le filtre modifie le contenu, mais pas sa taille
    

    
    byteranges=no
    
    
    Le filtre ne peut pas traiter de réponses à des sous-requêtes et
    nécessite des réponses complètes en entrée
    

    
    proxy=no
    
    
    Le filtre ne doit pas s'exécuter dans un contexte de mandataire
    

    
    proxy=transform
    
    
    Le filtre transforme la réponse de manière incompatible avec
    l'en-tête HTTP Cache-Control: no-transform
    

    
    cache=no
    
    
    Le filtre fait en sorte que la sortie ne puisse pas être mise en
    cache (par exemple en introduisant des modifications de contenu
    aléatoires)

    Açıklama:Belge ağacının parçalarının dosya sisteminin parçalarıyla
eşlenmesini sağlar ve URL yönlendirmesi yapar.

    Özet
    

    
    Bu modülde bulunan yönergeler sunucuya istek olarak gelen URL’lerin
      denetlenmesini ve değiştirilmesini mümkün kılar. Alias ve ScriptAlias yönergeleri URL’lerin dosya sisteminin
      dizinlerine eşlenmesini sağlar. Böylece, kök dizini DocumentRoot ile belirtilen site belge ağacı
      altında bulunmayan içeriğe erişmek mümkün olur. ScriptAlias yönergesi buna ek olarak
      hedef dizini sadece CGI betiklerini içeren dizin olarak imler.
    

    
    Redirect yönergesi,
      farklı bir URL ile yeni bir istek yapmaları için istemcileri
      yönlendirmekte kullanılır. Çoğunlukla özkaynak başka bir yere
      taşındığında kullanılır.
    

    
    Alias,
      ScriptAlias ve 
      Redirect yönergeleri
      <Location>
      veya <LocationMatch>
      bölümleri içinde kullanıldığında hedef yolu veya URL'yi betimlemek için 
      ifade sözdizimi kullanılabilir.
    
    
    
    
    mod_alias modülü basit URL değiştirme görevlerini
      yerine getirmek için tasarlanmıştır. Sorgu dizgelerini işleme sokmak
      gibi daha karmaşık görevler için mod_rewrite modülü ile
      sağlanan araçlar kullanılır.

    İşlem Sırası
    

    
    Farklı bağlamlarda bulunan Alias ve Redirect
      yönergeleri standart katıştırma
      kuralları ile ilgili diğer yönergeler gibi işleme sokulur. Fakat
      aynı bağlam dahilinde (örneğin, aynı <VirtualHost> bölümünde) çok fazla Alias ve Redirect varsa bunlar belli bir
      sıraya göre işleme sokulurlar.
    

    
    İlk adımda, Alias’lardan önce
      bütün Redirect yönergeleri
      işleme sokulur. Bu bakımdan bir Redirect veya RedirectMatch ile eşleşen bir istek için
      hiçbir Alias
      uygulanmayacaktır. İkinci adımda yapılandırma dosyasında yer aldıkları
      sıraya göre Redirect ve
      Alias yönergeleri işleme
      sokulurlar, dolayısıyla ilk eşleşme öncelikli olmuş olur.
    

    
    İlk eşleşmenin öncelikli olması sebebiyle, bu yönergelerin birden
      fazlası aynı alt yola uygulandığı takdirde, tüm yönergelerin etkili
      olabilmesi için en uzun yolu sıralamada en öne almalısınız. Örneğin
      aşağıdaki yapılandırma beklendiği gibi çalışacaktır:
    

    
    Alias "/foo/bar" "/baz"
Alias "/foo" "/gaq"
    


    
    Ama yukarıdaki iki satır ters sırada yerleştirilmiş olsaydı,
      /foo rumuzu  daima /foo/bar rumuzundan önce
      eşleşecek, dolayısıyla ikinci yönerge yok sayılacaktı.
    

    
    Alias,
      ScriptAlias ve 
      Redirect yönergeleri
      <Location>
      veya <LocationMatch>
      bölümleri içinde kullanıldığında bu yönergeler küresel olarak tanımlı
      Alias,
      ScriptAlias ve 
      Redirect yönergelerinden öncelikli olur.

    Alias Yönergesi
    

    

    Açıklama:URL’leri dosya sistemi konumlarıyla eşler.
    

    Sözdizimi:Alias [URL-yolu] dosya-yolu |
dizin-yolu
    

    Bağlam:sunucu geneli, sanal konak, dizin
    

    Durum:Temel
    

    Modül:mod_alias
    

    

    
    Alias yönergesi, belgelerin DocumentRoot dizininden farklı bir yerde
      saklanmasını mümkün kılar. URL-yolu ile başlayan
      URL’ler (% imlemesi çözüldükten sonra) dizin-yolu
      ile başlayan yerel dosyalarla eşlenir. URL-yolu,
      harf büyüklüğüne duyarsız sistemlerde bile harf büyüklüğüne
      duyarlıdır.
    

    
    Alias "/image" "/ftp/pub/image"
    


    
    http://example.com/image/foo.gif şeklinde bir istek,
      sunucunun /ftp/pub/image/foo.gif dosyasıyla yanıt vermesine
      sebep olurdu. Sadece tam yol parçaları eşleştirilir; bu bakımdan
      yukarıdaki Alias yapılandırması
      http://example.com/imagefoo.gif ile eşleşmez. Düzenli
      ifadelerin kullanıldığı daha karmaşık eşleşmeler için AliasMatch yönergesine bakınız.
    

    
    URL-yolu’nu bir / ile
      sonlandırırsanız Alias yönergesini yorumlarken
      sunucunun da sona bir / ekleyeceğine dikkat ediniz. Yani,
      eğer
    

    
    Alias "/icons/" "/usr/local/apache/icons/"
    


    
    diye bir tanım yaparsanız sona bir / ekleme ihtiyacından dolayı
      /icons URL’si için bir Alias
      kullanılmayacaktır.
    

    
    Alias hedefleri için ek <Directory> bölümleri
      belirtmeniz gerekebileceğine dikkat ediniz. <Directory> bölümlerinden önce yer alan
      Alias yönergelerine özellikle bakılır,
      dolayısıyla sadece Alias hedefleri etkilenir.
      (Bununla birlikte, Alias yönergelerinden önce
      işleme sokulan <Location> bölümlerinin uygulanacağına dikkat
      ediniz.)
    

    
    Özellikle, DocumentRoot dışında
      bir dizine bir Alias oluşturuyorsanız hedef
      dizine doğrudan erişim izni vermeniz gerekebilir.
    

    
    Alias "/image" "/ftp/pub/image"
<Directory "/ftp/pub/image">
    Require all granted
</Directory>
    


    
    URL-yolu değiştirgesindeki bölü çizgilerinin sayısı istek
      URL-yolundakiler kadardır.
    
    
    
    Eğer Alias yönergesi
      <Location>
      veya <LocationMatch>
      bölümleri içinde kullanılırsa URL-yolu yoksayılır ve dosya-yolu 
      ifade sözdizimi kullanılarak yorumlanır.
    
      Bu sözdizimi Apache 2.4.19 ve sonrasında kulanılabilir.
    
    
    
    <Location "/image">
    Alias "/ftp/pub/image"
</Location>
<LocationMatch "/error/(?<NUMBER>[0-9]+)">
    Alias "/usr/local/apache/errors/%{env:MATCH_NUMBER}.html"
</LocationMatch>
    


  

    

    top
    

    AliasMatch Yönergesi
    

    

    Açıklama:URL’leri dosya sistemi konumlarıyla düzenli ifadeleri kullanarak
eşler.
    

    Sözdizimi:AliasMatch "düzenli-ifade"
"dosya-yolu|dizin-yolu"
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Bu yönerge URL-yolu ile eşleşmek üzere bir
      düzenli ifade kabul etmesi dışında
      Alias yönergesine eşdeğerdir.
      Belirtilen düzenli ifade URL-yolu ile eşleşiyorsa
      sunucu parantezli eşleşmeleri belirtilen dizgede kullanarak dosya yolunu
      elde eder. Örneğin, /icons dizinini etkinleştirmek için şu
      yazılabilir:
    

    
    AliasMatch "^/icons(.*)" "/usr/local/apache/icons$1"
    


    
    Düzenli ifadelerin tamamı
      kullanılabilmektedir. Örneğin, URL-yolu ile harf
      büyüklüğüne duyarsız eşleşmeler sağlayacak takma adlar
      kullanılabilir:
    

    
    AliasMatch "(?i)^/image(.*)" "/ftp/pub/image$1"
    


    
    Alias
      ve AliasMatch yönergeleri
      arasındaki başlıca fark Alias
      yönergesinin, URI'nin ek parçasını, eşleşen parçayı geçip sağ tarafta
      dosya yolunun ucuna kendiliğinden kopyalamasıdır. AliasMatch bunu böyle yapmaz. Yani hemen
      her durumda, düzenli ifadenin istenen URI'nin tamamıyla baştan sona
      eşleşmesi ve yer değiştirmeyi sağ tarafta yapması istenir.
    

    
    Başka bir deyişle, basitçe
      Alias yerine
      AliasMatch yazmakla aynı etkiyi
      alamazsınız. En azından düzenli ifadenin başına bir ^ ve
      sonuna bir (.*)$, ikinci değiştirgenin sonuna da bir
      $1 eklemeniz gerekir.
    

    
    Örneğin aşağıdakini AliasMatch ile değiştirmek isteyelim:
    

    
    Alias "/image/" "/ftp/pub/image/"
    


    
    Bu eşdeğer DEĞİLdir - bunu yapmayın!  Bu herhangi bir yerinde /image/
      dizgesi bulunan tüm istekleri /ftp/pub/image/ altına gönderecektir:
    

    
    AliasMatch "/image/" "/ftp/pub/image/"
    


    
    Aynı etkiyi elde etmek için bu gerekiyor:
    

    
    AliasMatch "^/image/(.*)$" "/ftp/pub/image/$1"
    


    
    Şüphesiz, Alias yönergesini
      çalıştığı yerde AliasMatch
      kullanmanın hiç gereği yoktur. AliasMatch daha karmaşık şeyler yapmamızı sağlar. Örneğin
      farklı dosya çeşitlerini farklı dizinlerden sunmak isteyelim:
    

    
    AliasMatch "^/image/(.*)\.jpg$" "/files/jpg.images/$1.jpg"
AliasMatch "^/image/(.*)\.gif$" "/files/gif.images/$1.gif"
    


    
    İstek URL'sinin başındaki bölü çizgileri, bu modüldeki yönergeler istek
      URL-yolu ile eşleştirilmeye çalışılmadan önce sunucu tarafından
      yokedilir.

    Redirect Yönergesi
    

    

    Açıklama:İstemciyi, bir yönlendirme isteği döndürerek farklı bir URL’ye
yönlendirir.
    

    Sözdizimi:Redirect [durum] [URL-yolu]
URL
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:FileInfo
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Redirect yönergesi istemciye bir yönlendirme
      isteği döndürerek eski URL’yi yenisiyle eşler.
    

    
    Eski URL-yolu bir bölü çizgisi ile başlar ve harf
      büyüklüğüne duyarlıdır (% imlemesi çözüldükten sonra).
      URL-yolu olarak göreli yollara izin verilmez.
    

    
    URL ise ya bir şema ve konak ismi ile başlayan
      bir mutlak URL ya da bir bölü çizgisi ile başlayan bir URL yolu olabilir.
      İkinci durumda URL yolunun başına geçerli sunucu ismi ve şemayı sunucu
      ekler.
    

    
    URL-yolu ile başlayan istekler istemciye hedef
      URL konumuna bir yönlendirme isteği olarak
      dönecektir. URL-yolu’nun devamı niteliğindeki ek
      yol hedef URL’ye eklenir.
    

    
    # Farklı bir konaktaki bir URL'ye yönlendirme
Redirect "/hizmet" "http://iki.example.com/hizmet"

# Aynı konak üzerinde yönlendirme
Redirect "/bir" "/iki"
    


    
    İstemcinin yaptığı http://example.com/hizmet/fesmekan.txt
      isteğine karşılık istemciye isteği
      http://iki.example.com/hizmet/fesmekan.txt olarak yapması
      söylenecektir. Bu GET isteklerinde de geçerlidir. Örneğin,
      http://example.com/hizmet/foo.pl?q=23&a=42 isteği
      http://iki.example.com/hizmet/foo.pl?q=23&a=42 adresine
      yönlendirilir. POST'ların iptal edileceğini unutmayın.
    
      Sadece tam yol parçaları eşleştirilir, bu nedenle
      http://example.com/hizmetfesmekan.txt isteği yukarıdaki
      yönlendirme ile eşleşmeyecektir. İfade 
      sözdizimi kullanılan daha karmaşık eşleşmeler için URL-yolu seçeneği 
      aşağıda açıklandığı gibi yoksayılır. Düzenli ifadelerin kullanıldığı daha 
      karmaşık eşleşmeler için RedirectMatch
      yönergesine de bakınız.
    


    
    Bilginize
    
      
    Yapılandırma dosyasında yer alış sırasına bakmaksızın
        Redirect yönergeleri
        Alias ve ScriptAlias
        yönergelerinden önce ele alınır. <Location> bölümü içinde kullanılmış bir  
        Redirect yönergesi URL-yolu belirtilmiş  
        Redirect ve  Alias 
        yönergelerine göre önceliklidir.
    

      
    Herhangi bir durum belirtilmemişse "geçici"
        yönlendirme (HTTP durum kodu: 302) yapılır. Bu, istemciye özkaynağın
        geçici olarak başka yere taşındığını belirtir. Diğer HTTP durum
        kodlarını döndürmek için kullanılabilecek durum
        değerleri:
    

    
    
      
    permanent
    
      
    İstemciye özkaynağın kalıcı olarak taşındığını belirten kalıcı
        yönlendirme durumu (301) döndürülür.
    

      
    temp
    
      
    İstemciye geçici yönlendirme durumu (302) döner. Bu öntanımlıdır.
      
    

      
    seeother
    
      
    İstemciye özkaynağın yerine başka bir şey konduğunu belirten
        "diğerine bak" durumu (303) döndürülür.
    

      
    gone
    
      
    İstemciye özkaynağın kalıcı olarak kaldırıldığını belirten "ölü
        bağlantı" durumu (410) döner. Bu durumda URL
        belirtilmez.
    
    
    

    
    Diğer durum kodları için durum değiştirgesiyle
      sayısal durum kodu belirtilir. Eğer durum 300 ile 399 arasındaysa bir
      URL belirtmek gereklidir. Aksi takdirde,
      URL bileşeni ihmal edilmelidir. Belirtilecek durum kodunun
      geçerli bir HTTP Status kodu olmalı ve Apache HTTP Sunucusu kodu
      bilmelidir (http_protocol.c dosyasında bulunan
      send_error_response işlevine bakınız).
    

    
    Redirect permanent "/bir" "http://example.com/iki"
Redirect 30" "/yedi" http://example.com/baskabisey"
    


    
    Eğer Redirect yönergesi URL-yolu belirtilmemiş 
      bir <Location>
      veya <LocationMatch>
      bölümü içinde yer alıyorsa, URL seçeneği ifade 
      sözdizimi kullanılarak yorumlanır.
    
      Bu sözdizimi Apache 2.4.19 ve sonrasında kullanılabilir.
    

    
    <Location "/bir">
    Redirect permanent "http://example.com/iki"

<Location "/yedi">
    Redirect 303 "http://example.com/baskabisey"

    RedirectMatch Yönergesi
    

    

    Açıklama:Geçerli URL ile eşleşen bir düzenli ifadeye dayanarak bir harici
yönlendirme gönderir.
    

    Sözdizimi:RedirectMatch [durum] düzenli-ifade
URL
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:FileInfo
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Bu yönerge URL-yolu ile eşleşmek üzere bir
      düzenli ifade kabul etmesi dışında
      Redirect yönergesine
      eşdeğerdir. Belirtilen düzenli ifade URL-yolu ile
      eşleşiyorsa sunucu parantezli eşleşmeleri belirtilen dizgede kullanarak
      dosya yolunu elde eder. Örneğin, tüm GIF dosyası isteklerini başka bir
      sunucudaki aynı isimli JPEG dosyalarına yönlendirmek için şu
      yazılabilir:
    

    
    RedirectMatch "(.*)\.gif$" "http://baska.example.com$1.jpg"
    


    
    Alias ve
      AliasMatch arasındaki farklarla
      ilgili hususlar Redirect ve
      RedirectMatch arasındakilere de
      uygulanır. Ayrıntılar için  AliasMatch yönergesine bakınız.

    RedirectPermanent Yönergesi
    

    

    Açıklama:İstemciyi, kalıcı bir yönlendirme isteği döndürerek farklı bir
URL’ye yönlendirir.
    

    Sözdizimi:RedirectPermanent URL-yolu URL
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:FileInfo
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Bu yönerge istemciye daima kalıcı yönlendirme durumu (301) döndürür.
      Yani, Redirect permanent ile aynı işi yapar.
    
  

    

    top
    

    RedirectTemp Yönergesi
    

    

    Açıklama:İstemciyi, geçici bir yönlendirme isteği döndürerek farklı bir
URL’ye yönlendirir.
    

    Sözdizimi:RedirectTemp URL-yolu URL
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:FileInfo
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Bu yönerge istemciye daima geçici yönlendirme durumu (302) döndürür.
      Yani, Redirect temp ile aynı işi yapar.

    ScriptAlias Yönergesi
    

    

    Açıklama:Bir URL’yi dosya sistemindeki bir yere eşler ve hedefi bir CGI betiği olarak çalıştırır.
    

    Sözdizimi:ScriptAlias [URL-yolu]
dosya-yolu|dizin-yolu
    

    Bağlam:sunucu geneli, sanal konak, dizin
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Hedef dizini, mod_cgi modülünün CGI betiği
      yorumlayıcısı tarafından çalıştırılacak betikleri içeren dizin olarak
      imlemesi dışında Alias
      yönergesinin yaptığı işi yapar. URL-yolu ile
      başlayan harf büyüklüğüne duyarlı URL’ler (% imlemesi çözüldükten
      sonra), dosya sistemindeki bir tam yol olarak belirtilmiş
      dizin-yolu ile başlayan betiklerle eşlenir.
    

    
    ScriptAlias "/cgi-bin/" "/siteler/cgi-bin/"
    


    
    http://example.com/cgi-bin/foo şeklindeki bir istek
      sunucunun /siteler/cgi-bin/foo betiğini çalıştırmasına sebep
      olur. Bu yapılandırma aslında şuna eşdeğerdir:
    

    
    Alias "/cgi-bin/" "/siteler/cgi-bin/"
<Location "/cgi-bin">
    SetHandler cgi-script
    Options +ExecCGI
</Location>
    


    
    ScriptAlias yönergesini bir betik veya eylemci
      ile birlikte de kullanabilirsiniz. Örnek:
    

       
    ScriptAlias "/cgi-bin/" "/siteler/cgi-handler.pl"
    


    
    Bu senaryoda /cgi-bin/’den istenen tüm dosyalar sizin
      belirttiğiniz dosya tarafından işleme sokulacaktır. Bu yöntemle kendi
      özel eylemcinizi kullanabilirsiniz. İsterseniz, bunu içerik eklemek
      ya da ısmarlama bir eylem için bir CGI sarmalayıcısı olarak da
      kullanabilirsiniz.
    

    
    Yapılandırma değiştiğinde kaynak kodlarının ister
      istemez açığa çıkmasını istemiyorsanız CGI betiklerinizi DocumentRoot altına koymayınız.
      ScriptAlias yönergesi URL’yi doğru yere
      eşlemekten başka orayı bir CGI betikleri dizini olarak imler. CGI
      betiklerinizi DocumentRoot altına
      koyarsanız çalıştırmak için ScriptAlias değil,
      <Directory>,
      SetHandler ve Options yönergelerini örnekteki gibi kullanın:

    
    <Directory "/usr/local/apache2/htdocs/cgi-bin" >
    SetHandler cgi-script
    Options ExecCGI
</Directory>
    


     Aynı dosya sistemi konumu ile çok sayıda URL-yolu
     eşleşebileceğinden, bir Directory
     bölümü ile sınırlanmadığı takdirde CGI betiklerinin kaynak kodları açığa
     çıkabilir; bu bakımdan ScriptAlias yönergesini yok
     sayan URL yollarının belirtilebilme olasılığı gözardı
     edilmemelidir.
    
   
    
    Eğer ScriptAlias yönergesi URL-yolu belirtilmemiş 
      bir <Location>
      veya <LocationMatch>
      bölümü içinde yer alıyorsa, URL seçeneği ifade 
      sözdizimi kullanılarak yorumlanır.
    
      Bu sözdizimi Apache 2.4.19 ve sonrasında kullanılabilir.
    

    
    <Location "/cgi-bin">
    ScriptAlias "/siteler/cgi-bin/"
</Location>
<LocationMatch "/cgi-bin/errors/(?<NUMBER>[0-9]+)">
    ScriptAlias "/siteler/cgi-bin/errors/%{env:MATCH_NUMBER}.cgi"
</LocationMatch>

    ScriptAliasMatch Yönergesi

eşler ve hedefi bir CGI betiği olarak çalıştırır.
    

    Sözdizimi:ScriptAliasMatch düzenli-ifade
dosya-yolu|dizin-yolu
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Temel
    

    Modül:mod_alias
    

    
    
    Bu yönerge URL-yolu ile eşleşmek üzere bir
      düzenli ifade kabul etmesi dışında
      ScriptAlias yönergesine
      eşdeğerdir. Belirtilen düzenli ifade URL-yolu ile
      eşleşiyorsa sunucu parantezli eşleşmeleri belirtilen dizgede kullanarak
      dosya yolunu elde eder. Örneğin, standart /cgi-bin dizinini
      etkin kılmak için şu yazılabilir:
    

    
    ScriptAliasMatch "^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"
    


    
    AliasMatch yönergesindeki gibi, düzenli
      ifadelerin tamamı tüm güçleriyle kullanılabilmektedir.
      Örneğin, URL-yolu için harf büyüklüğüne duyarsız
      eşleşmeli bir takma ad oluşturmak mümkünür:
    

    
    ScriptAliasMatch "(?i)^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"
    


    
    Alias ve
      AliasMatch arasındaki farklarla
      ilgili hususlar ScriptAlias ve
      ScriptAliasMatch arasındakilere
      de uygulanır. Ayrıntılar için  AliasMatch yönergesine bakınız.

    Apache Module mod_actions

    Description:Execute CGI scripts based on media type or request method.
    

    Status:Base
    

    Module Identifier:actions_module
    

    Source File:mod_actions.c
    

    Summary
    

    
    This module has two directives. The Action directive lets you run CGI
    scripts whenever a file of a certain MIME content type is requested. The
    Script directive lets
    you run CGI scripts whenever a particular method is used in a
    request. This makes it much easier to execute scripts that process
    files.
     
    



    top
    

    Action Directive
    

    

    Description:Activates a CGI script for a particular handler or
content-type
    

    Syntax:Action action-type cgi-script [virtual]
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_actions
    

    Compatibility:The virtual modifier and handler passing were
introduced in Apache 2.1
    

    
    
    This directive adds an action, which will activate
    cgi-script when action-type is triggered by
    the request.  The cgi-script is the URL-path to a
    resource that has been designated as a CGI script using ScriptAlias or AddHandler.  The
    action-type can be either a handler or a MIME content type. It sends the URL and
    file path of the requested document using the standard CGI
    PATH_INFO and PATH_TRANSLATED
    environment variables. The handler used for the particular request
    is passed using the REDIRECT_HANDLER variable.
    

    
    Example: MIME type
    # Requests for files of a particular MIME content type:
Action image/gif /cgi-bin/images.cgi
    

    

    
    In this example, requests for files with a MIME content
    type of image/gif will be handled by the
    specified cgi script /cgi-bin/images.cgi.
    

    
    Example: File extension
    # Files of a particular file extension
AddHandler my-file-type .xyz
Action my-file-type "/cgi-bin/program.cgi"
    

    
    
    In this example, requests for files with a file extension of
    .xyz are handled by the specified cgi script
    /cgi-bin/program.cgi.
    

    
    The optional virtual modifier turns off the check
    whether the requested file really exists. This is useful, for example,
    if you want to use the Action directive in
    virtual locations.
    

    
    <Location "/news">
    SetHandler news-handler
    Action news-handler "/cgi-bin/news.cgi" virtual
</Location>

    Script Directive
    

    

    Description:Activates a CGI script for a particular request
method.
    

    Syntax:Script method cgi-script
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_actions
    

    
    
    This directive adds an action, which will activate
    cgi-script when a file is requested using the method of
    method. The cgi-script is the URL-path to a
    resource that has been designated as a CGI script using ScriptAlias or AddHandler.  The URL and
    file path of the requested document is sent using the standard CGI
    PATH_INFO and PATH_TRANSLATED environment
    variables.
    

    
    
      Any arbitrary method name may be used. Method names are
      case-sensitive, so Script PUT and
      Script put have two entirely different
      effects.
    
    

    
    Note that the Script command defines default
    actions only. If a CGI script is called, or some other resource that is
    capable of handling the requested method internally, it will do
    so. Also note that Script with a method of
    GET will only be called if there are query arguments present
    (e.g., foo.html?hi). Otherwise, the request will
    proceed normally.
    

    
    # All GET requests go here
Script GET "/cgi-bin/search"

# A CGI PUT handler
Script PUT "/~bob/put.cgi"

    Summary
    

    
    This module should be used with care, as when the
    CacheQuickHandler directive is
    in its default value of on, the Allow and Deny directives will be circumvented.
    You should not enable quick handler caching for any content to which you
    wish to limit access by client host name, address or environment
    variable.
    

    
    mod_cache implements an RFC 2616 compliant
    HTTP content caching filter, with support for the caching
    of content negotiated responses containing the Vary header.
    

    
    RFC 2616 compliant caching provides a mechanism to verify whether
    stale or expired content is still fresh, and can represent a significant
    performance boost when the origin server supports conditional
    requests by honouring the
    If-None-Match
    HTTP request header. Content is only regenerated from scratch when the content
    has changed, and not when the cached entry expires.
    

    
    As a filter, mod_cache can be placed in front of
    content originating from any handler, including flat
    files (served from a slow disk cached on a fast disk), the output
    of a CGI script or dynamic content
    generator, or content proxied from another
    server.
    

    
    In the default configuration, mod_cache inserts the
    caching filter as far forward as possible within the filter stack,
    utilising the quick handler to bypass all per request
    processing when returning content to the client. In this mode of
    operation, mod_cache may be thought of as a caching
    proxy server bolted to the front of the webserver, while running within
    the webserver itself.
    

    
    When the quick handler is switched off using the
    CacheQuickHandler directive,
    it becomes possible to insert the CACHE filter at a
    point in the filter stack chosen by the administrator. This provides the
    opportunity to cache content before that content is personalised by the
    mod_include filter, or optionally compressed by the
    mod_deflate filter.
    

    
    Under normal operation, mod_cache will respond to
    and can be controlled by the
    Cache-Control
    and
    Pragma
    headers sent from a client in a request, or from a
    server within a response. Under exceptional circumstances,
    mod_cache can be configured to override these headers
    and force site specific behaviour, however such behaviour will be limited
    to this cache only, and will not affect the operation of other caches
    that may exist between the client and server, and as a result is not
    recommended unless strictly necessary.
    

    
    RFC 2616 allows for the cache to return stale data while the existing
    stale entry is refreshed from the origin server, and this is supported
    by mod_cache when the
    CacheLock directive is suitably
    configured. Such responses will contain a
    Warning
    HTTP header with a 110 response code. RFC 2616 also allows a cache to return
    stale data when the attempt made to refresh the stale data returns an
    error 500 or above, and this behaviour is supported by default by
    mod_cache. Such responses will contain a
    Warning
    HTTP header with a 111 response code.
    

    
    mod_cache requires the services of one or more
    storage management modules. The following storage management modules are included in
    the base Apache distribution:
    
    
    
    
    mod_cache_disk
    
    
    Implements a disk based storage manager. Headers and bodies are
    stored separately on disk, in a directory structure derived from the
    md5 hash of the cached URL. Multiple content negotiated responses can
    be stored concurrently, however the caching of partial content is not
    supported by this module. The htcacheclean tool is
    provided to list cached URLs, remove cached URLs, or to maintain the size
    of the disk cache within size and inode limits.
    
    
    mod_cache_socache
    
    
    Implements a shared object cache based storage manager. Headers and
    bodies are stored together beneath a single key based on the URL of the
    response being cached. Multiple content negotiated responses can
    be stored concurrently, however the caching of partial content is not
    supported by this module.
    
    
    

    
    Further details, discussion, and examples, are provided in the
    Caching Guide.

    Avoiding the Thundering Herd
    
  
    When a cached entry becomes stale, mod_cache will submit
  a conditional request to the backend, which is expected to confirm whether the
  cached entry is still fresh, and send an updated entity if not.
    
  
    A small but finite amount of time exists between the time the cached entity
  becomes stale, and the time the stale entity is fully refreshed. On a busy
  server, a significant number of requests might arrive during this time, and
  cause a thundering herd of requests to strike the backend
  suddenly and unpredictably.
    
  
    To keep the thundering herd at bay, the CacheLock
  directive can be used to define a directory in which locks are created for
  URLs in flight. The lock is used as a hint
  by other requests to either suppress an attempt to cache (someone else has
  gone to fetch the entity), or to indicate that a stale entry is being refreshed
  (stale content will be returned in the mean time).
  
    
  
    Initial caching of an entry
    
    
    
    When an entity is cached for the first time, a lock will be created for the
    entity until the response has been fully cached. During the lifetime of the
    lock, the cache will suppress the second and subsequent attempt to cache the
    same entity. While this doesn't hold back the thundering herd, it does stop
    the cache attempting to cache the same entity multiple times simultaneously.
    
    
  
  
    Refreshment of a stale entry
    
    
    
    When an entity reaches its freshness lifetime and becomes stale, a lock
    will be created for the entity until the response has either been confirmed as
    still fresh, or replaced by the backend. During the lifetime of the lock, the
    second and subsequent incoming request will cause stale data to be returned,
    and the thundering herd is kept at bay.
    
  
  
    Locks and Cache-Control: no-cache
    
    
    
    Locks are used as a hint only to enable the cache to be
    more gentle on backend servers, however the lock can be overridden if necessary.
    If the client sends a request with a Cache-Control header forcing a reload, any
    lock that may be present will be ignored, and the client's request will be
    honored immediately and the cached entry refreshed.
    
    
    As a further safety mechanism, locks have a configurable maximum age.
    Once this age has been reached, the lock is removed, and a new request is
    given the opportunity to create a new lock. This maximum age can be set using
    the CacheLockMaxAge directive, and defaults
    to 5 seconds.
    
    
  
  
    Example configuration
    
    
    
    Enabling the cache lock
    #
# Enable the cache lock
#
<IfModule mod_cache.c>
    CacheLock on
    CacheLockPath "/tmp/mod_cache-lock"
    CacheLockMaxAge 5
</IfModule>

    Fine Control with the CACHE Filter
    
  
    Under the default mode of cache operation, the cache runs as a quick handler,
  short circuiting the majority of server processing and offering the highest
  cache performance available.
    

  
    In this mode, the cache bolts onto the front of the server,
  acting as if a free standing RFC 2616 caching proxy had been placed in front of
  the server.
    

  
    While this mode offers the best performance, the administrator may find that
  under certain circumstances they may want to perform further processing on the
  request after the request is cached, such as to inject personalisation into the
  cached page, or to apply authorization restrictions to the content. Under these
  circumstances, an administrator is often forced to place independent reverse
  proxy servers either behind or in front of the caching server to achieve this.
    

  
    To solve this problem the CacheQuickHandler
  directive can be set to off, and the server will
  process all phases normally handled by a non-cached request, including the
  authentication and authorization phases.
    

  
    In addition, the administrator may optionally specify the precise point
  within the filter chain where caching is to take place by adding the
  CACHE filter to the output filter chain.
    

  
    For example, to cache content before applying compression to the response,
  place the CACHE filter before the DEFLATE
  filter as in the example below:
    

  
    # Cache content before optional compression
CacheQuickHandler off
AddOutputFilterByType CACHE;DEFLATE text/plain
    


  
    Another option is to have content cached before personalisation is applied
  by mod_include (or another content processing filter). In this
  example templates containing tags understood by
  mod_include are cached before being parsed:
    

  
    # Cache content before mod_include and mod_deflate
CacheQuickHandler off
AddOutputFilterByType CACHE;INCLUDES;DEFLATE text/html
    


  
    You may place the CACHE filter anywhere you wish within the
  filter chain. In this example, content is cached after being parsed by
  mod_include, but before being processed by
  mod_deflate:
    

  
    # Cache content between mod_include and mod_deflate
CacheQuickHandler off
AddOutputFilterByType INCLUDES;CACHE;DEFLATE text/html
    


  
    Warning:
    If the location of the
  CACHE filter in the filter chain is changed for any reason,
  you may need to flush your cache to ensure that your data
  served remains consistent. mod_cache is not in a position
  to enforce this for you.

    Cache Status and Logging
    
  
    Once mod_cache has made a decision as to whether or not
  an entity is to be served from cache, the detailed reason for the decision
  is written to the subprocess environment within the request under the
  cache-status key. This reason can be logged by the
  LogFormat directive as
  follows:
    

  
    LogFormat "%{cache-status}e ..."
    


  
    Based on the caching decision made, the reason is also written to the
  subprocess environment under one the following four keys, as appropriate:
    

  
    
    
    cache-hit
    The response was served from cache.
    
    
    cache-revalidate
    The response was stale and was successfully
      revalidated, then served from cache.
    
    
    cache-miss
    The response was served from the upstream server.
    
    
    cache-invalidate
    The cached entity was invalidated by a request
      method other than GET or HEAD.
    
  
    

  
    This makes it possible to support conditional logging of cached requests
  as per the following example:
    

  
    CustomLog "cached-requests.log" common env=cache-hit
CustomLog "uncached-requests.log" common env=cache-miss
CustomLog "revalidated-requests.log" common env=cache-revalidate
CustomLog "invalidated-requests.log" common env=cache-invalidate
    


  
    For module authors, a hook called cache_status is available,
  allowing modules to respond to the caching outcomes above in customised
  ways.

    CacheDefaultExpire Directive
    

    

    Description:The default duration to cache a document when no expiry date is specified.

    The CacheDefaultExpire directive specifies a default time,
    in seconds, to cache a document if neither an expiry date nor last-modified date are provided
    with the document. The value specified with the CacheMaxExpire
    directive does not override this setting.

    Status:Extension
    

    Module:mod_cache
    

    Compatibility:Available in Apache 2.3.9 and later
    

    
  
    When the CacheDetailHeader directive
  is switched on, an X-Cache-Detail header will be added to the response
  containing the detailed reason for a particular caching decision.
    

  
    It can be useful during development of cached RESTful services to have additional
  information about the caching decision written to the response headers, so as to
  confirm whether Cache-Control and other headers have been correctly
  used by the service and client.
    

  
    If the normal handler is used, this directive may appear within a
  <Directory> or
  <Location> directive. If the quick handler
  is used, this directive must appear within a server or virtual host context, otherwise
  the setting will be ignored.
    

  
    # Enable the X-Cache-Detail header

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    The CacheDisable directive instructs
    mod_cache to not cache urls at or below
    url-string.
    

    
    Example
    CacheDisable "/local_files"
    

    

    
    If used in a <Location> directive,
    the path needs to be specified below the Location, or if the word "on"
    is used, caching for the whole location will be disabled.
    

    
    Example
    <Location "/foo">
    CacheDisable on
</Location>
    

    

    
    The no-cache environment variable can be set to
    disable caching on a finer grained set of resources in versions
    2.2.12 and later.

    CacheEnable Directive
    

    

    Description:Enable caching of specified URLs using a specified storage
manager
    

    Syntax:CacheEnable cache_type [url-string]
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_cache
    

    Compatibility:A url-string of '/' applied to forward proxy content in 2.2 and
 earlier.
    

    
    
    The CacheEnable directive instructs
    mod_cache to cache urls at or below
    url-string. The cache storage manager is specified with the
    cache_type argument. The CacheEnable
    directive can alternatively be placed inside either
    <Location> or
    <LocationMatch> sections to indicate
    the content is cacheable.
    cache_type disk instructs
    mod_cache to use the disk based storage manager
    implemented by mod_cache_disk. cache_type
    socache instructs mod_cache to use the
    shared object cache based storage manager implemented by
    mod_cache_socache.
    
    
    In the event that the URL space overlaps between different
    CacheEnable directives (as in the example below),
    each possible storage manager will be run until the first one that
    actually processes the request. The order in which the storage managers are
    run is determined by the order of the CacheEnable
    directives in the configuration file. CacheEnable
    directives within <Location> or
    <LocationMatch> sections are processed
    before globally defined CacheEnable directives.
    

    
    When acting as a forward proxy server, url-string must
    minimally begin with a protocol for which caching should be enabled.
    

    
    # Cache content (normal handler only)
CacheQuickHandler off
<Location "/foo">
    CacheEnable disk
</Location>

# Cache regex (normal handler only)
CacheQuickHandler off
<LocationMatch "foo$">
    CacheEnable disk
</LocationMatch>

# Cache all but forward proxy url's (normal or quick handler)
CacheEnable  disk  /

# Cache FTP-proxied url's (normal or quick handler)
CacheEnable  disk  ftp://

# Cache forward proxy content from www.example.org (normal or quick handler)
CacheEnable  disk  http://www.example.org/
    


    
    A hostname starting with a "*" matches all hostnames with
    that suffix. A hostname starting with "." matches all
    hostnames containing the domain components that follow.
    

    
    # Match www.example.org, and fooexample.org
CacheEnable  disk  "http://*example.org/"
# Match www.example.org, but not fooexample.org
CacheEnable  disk  "http://.example.org/"
    


    
     The no-cache environment variable can be set to
    disable caching on a finer grained set of resources in versions
    2.2.12 and later.

    Ordinarily, requests containing a Cache-Control: no-cache or
    Pragma: no-cache header value will not be served from the cache.  The
    CacheIgnoreCacheControl directive allows this
    behavior to be overridden.  CacheIgnoreCacheControl On
    tells the server to attempt to serve the resource from the cache even
    if the request contains no-cache header values.  Resources requiring
    authorization will never be cached.

    Module:mod_cache
    

    
    
    According to RFC 2616, hop-by-hop HTTP headers are not stored in
    the cache.  The following HTTP headers are hop-by-hop headers and thus
    do not get stored in the cache in any case regardless of the
    setting of CacheIgnoreHeaders:
    

    
      
      
    • Connection
      •

      • 
    
    

    
    CacheIgnoreHeaders specifies additional HTTP
    headers that should not to be stored in the cache.  For example, it makes
    sense in some cases to prevent cookies from being stored in the cache.
    

    
    CacheIgnoreHeaders takes a space separated list
    of HTTP headers that should not be stored in the cache. If only hop-by-hop
    headers not should be stored in the cache (the RFC 2616 compliant
    behaviour), CacheIgnoreHeaders can be set to
    None.

    for each unique query string. This is according to RFC 2616/13.9 done only
    if an expiration time is specified. The
    CacheIgnoreQueryString directive tells the cache to
    cache requests even if no expiration time is specified, and to reply with
    a cached reply even if the query string differs. From a caching point of
    view the request is treated as if having no query string when this
    directive is enabled.

    CacheIgnoreURLSessionIdentifiers Directive
    

    

    Description:Ignore defined session identifiers encoded in the URL when caching

    

    Syntax:CacheIgnoreURLSessionIdentifiers identifier [identifier] ...
    

    Default:CacheIgnoreURLSessionIdentifiers None
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    Sometimes applications encode the session identifier into the URL like in the following
    Examples:
    
    
    
      
      
    • /someapplication/image.gif;jsessionid=123456789
      • 
      
    • /someapplication/image.gif?PHPSESSIONID=12345678
      • 
    
    
    
    This causes cacheable resources to be stored separately for each session, which
    is often not desired. CacheIgnoreURLSessionIdentifiers lets
    define a list of identifiers that are removed from the key that is used to identify
    an entity in the cache, such that cacheable resources are not stored separately for
    each session.
    
    
    
    CacheIgnoreURLSessionIdentifiers None clears the list of ignored
    identifiers. Otherwise, each identifier is added to the list.
    

    
    Example 1
    CacheIgnoreURLSessionIdentifiers jsessionid
    

    

    
    Example 2
    CacheIgnoreURLSessionIdentifiers None

    CacheKeyBaseURL Directive
    

    

    Description:Override the base URL of reverse proxied cache keys.
    

    Syntax:CacheKeyBaseURL URL
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache
    

    Compatibility:Available in Apache 2.3.9 and later
    

    
  
    When the CacheKeyBaseURL directive
  is specified, the URL provided will be used as the base URL to calculate
  the URL of the cache keys in the reverse proxy configuration. When not specified,
  the scheme, hostname and port of the current virtual host is used to construct
  the cache key. When a cluster of machines is present, and all cached entries
  should be cached beneath the same cache key, a new base URL can be specified
  with this directive.
    

  
    # Override the base URL of the cache key.
CacheKeyBaseURL "http://www.example.com/"
    


  
    Take care when setting this directive. If two separate virtual
  hosts are accidentally given the same base URL, entries from one virtual host
  will be served to the other.

    CacheLastModifiedFactor Directive
    

    

    Description:The factor used to compute an expiry date based on the
LastModified date.
    

    Syntax:CacheLastModifiedFactor float
    

    Default:CacheLastModifiedFactor 0.1
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    In the event that a document does not provide an expiry date but does
    provide a last-modified date, an expiry date can be calculated based on
    the time since the document was last modified. The
    CacheLastModifiedFactor directive specifies a
    factor to be used in the generation of this expiry date
    according to the following formula:

    expiry-period = time-since-last-modified-date * factor
    expiry-date = current-date + expiry-period

    For example, if the document was last modified 10 hours ago, and
    factor is 0.1 then the expiry-period will be set to
    10*0.1 = 1 hour. If the current time was 3:00pm then the computed
    expiry-date would be 3:00pm + 1hour = 4:00pm.

    If the expiry-period would be longer than that set by
    CacheMaxExpire, then the latter takes
    precedence.
    

    
    CacheLastModifiedFactor 0.5

    CacheLock Directive
    

    

    Description:Enable the thundering herd lock.
    

    Syntax:CacheLock on|off
    

    Default:CacheLock off
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache
    

    Compatibility:Available in Apache 2.2.15 and later
    

    
  
    The CacheLock directive enables the thundering herd lock
  for the given URL space.
    

  
    In a minimal configuration the following directive is all that is needed to
  enable the thundering herd lock in the default system temp directory.
    

  
    # Enable cache lock
CacheLock on

    CacheLockMaxAge Directive
    

    

    Description:Set the maximum possible age of a cache lock.
    

    Syntax:CacheLockMaxAge integer
    

    Default:CacheLockMaxAge 5
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache
    

    
  
    The CacheLockMaxAge directive specifies the maximum
  age of any cache lock.
    

  
    A lock older than this value in seconds will be ignored, and the next
  incoming request will be given the opportunity to re-establish the lock.
  This mechanism prevents a slow client taking an excessively long time to refresh
  an entity.
    



    

    top
    

    CacheLockPath Directive
    

    

    Description:Set the lock path directory.
    

    Syntax:CacheLockPath directory
    

    Default:CacheLockPath /tmp/mod_cache-lock
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache
    

    
  
    The CacheLockPath directive allows you to specify the
  directory in which the locks are created. By default, the system's temporary
  folder is used. Locks consist of empty files that only exist for stale URLs
  in flight, so is significantly less resource intensive than the traditional
  disk cache.

    CacheMaxExpire Directive
    

    

    Description:The maximum time in seconds to cache a document
    

    Syntax:CacheMaxExpire seconds
    

    Default:CacheMaxExpire 86400 (one day)
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    The CacheMaxExpire directive specifies the maximum number of
    seconds for which cacheable HTTP documents will be retained without checking the origin
    server. Thus, documents will be out of date at most this number of seconds. This maximum
    value is enforced even if an expiry date was supplied with the document.
    

    
    CacheMaxExpire 604800

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    The CacheMinExpire directive specifies the minimum number of
    seconds for which cacheable HTTP documents will be retained without checking the origin
    server. This is only used if no valid expire time was supplied with the document.

    CacheQuickHandler Directive
    

    

    Description:Run the cache from the quick handler.
    

    Syntax:CacheQuickHandler on|off
    

    Default:CacheQuickHandler on
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache
    

    Compatibility:Apache HTTP Server 2.3.3 and later
    

    
    
    The CacheQuickHandler directive
    controls the phase in which the cache is handled.
    

    
    In the default enabled configuration, the cache operates within the quick
    handler phase. This phase short circuits the majority of server processing,
    and represents the most performant mode of operation for a typical server.
    The cache bolts onto the front of the server, and the
    majority of server processing is avoided.
    

    
    When disabled, the cache operates as a normal handler, and is subject to
    the full set of phases when handling a server request. While this mode is
    slower than the default, it allows the cache to be used in cases where full
    processing is required, such as when content is subject to authorization.
    

    
    # Run cache as a normal handler
CacheQuickHandler off
    


    
    It is also possible, when the quick handler is disabled, for the
    administrator to choose the precise location within the filter chain where
    caching is to be performed, by adding the CACHE filter to
    the chain.
    

    
    # Cache content before mod_include and mod_deflate
CacheQuickHandler off
AddOutputFilterByType CACHE;INCLUDES;DEFLATE text/html
    


    
    If the CACHE filter is specified more than once, the last instance will
    apply.

    CacheStaleOnError Directive
    

    

    Description:Serve stale content in place of 5xx responses.
    

    Syntax:CacheStaleOnError on|off
    

    Default:CacheStaleOnError on
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    Compatibility:Available in Apache 2.3.9 and later
    

    
  
    When the CacheStaleOnError directive
  is switched on, and when stale data is available in the cache, the cache will
  respond to 5xx responses from the backend by returning the stale data instead of
  the 5xx response. While the Cache-Control headers sent by clients will be respected,
  and the raw 5xx responses returned to the client on request, the 5xx response so
  returned to the client will not invalidate the content in the cache.
    

  
    # Serve stale data on error.
CacheStaleOnError on

    CacheStoreExpired Directive
    

    

    Description:Attempt to cache responses that the server reports as expired

    Default:CacheStoreExpired Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    Since httpd 2.2.4, responses which have already expired are not
       stored in the cache.  The CacheStoreExpired
       directive allows this behavior to be overridden.
       CacheStoreExpired On
       tells the server to attempt to cache the resource if it is stale.
       Subsequent requests would trigger an If-Modified-Since request of
       the origin server, and the response may be fulfilled from cache
       if the backend resource has not changed.

    CacheStoreNoStore Directive

    Default:CacheStoreNoStore Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache
    

    
    
    Ordinarily, requests or responses with Cache-Control: no-store header
       values will not be stored in the cache.  The
       CacheStoreNoStore directive allows this
       behavior to be overridden.  CacheStoreNoStore On
       tells the server to attempt to cache the resource even if it contains
       no-store header values.  Resources requiring authorization will
       never be cached.
    

    
    CacheStoreNoStore On
    


    
    Warning:
    
       As described in RFC 2616, the no-store directive is intended to
       "prevent the inadvertent release or retention of sensitive information
       (for example, on backup tapes)."  Enabling this option could store
       sensitive information in the cache.  You are hereby warned.

       directive allows this behavior to be overridden.
       CacheStorePrivate On
       tells the server to attempt to cache the resource even if it contains
       private header values.  Resources requiring authorization will
       never be cached.
    

    
    CacheStorePrivate On
    


    
    Warning:
    
       This directive will allow caching even if the upstream server has
       requested that the resource not be cached.  This directive is only
       ideal for a 'private' cache.

    モジュール識別子:include_module
    

    ソースファイル:mod_include.c
    

    互換性:Apache 2.0 から出力フィルタとして実装されました。
    

    概要
    

    
    このモジュールはファイルがクライアントに送られる前に処理するフィルタを
    提供します。処理の内容は要素と呼ばれる特別な形式の SGML コメントにより
    制御されます。これらの要素は条件分岐や、他のファイルや
    プログラムの出力の取り込み、環境変数の設定や表示を行なうことが
    できます。

    Server-Side Includes を有効にする
    
    

    
    Server Side Includes は INCLUDES
    フィルタ により実装されています。
    Server-side include のディレクティブを含むドキュメントの拡張子が
    .shtml の場合、以下のディレクティブでは Apache がそれらを
    パースして、その結果できるドキュメントに text/html の
    MIME タイプを割り当てます:
    

    
    
      AddType text/html .shtml
    
      AddOutputFilter INCLUDES .shtml
    
    

    
    以下のディレクティブは shtml ファイルのあるディレクトリで指定されている
    必要があります (通常は <Directory> セクションで指定しますが、
    AllowOverride Options
    が設定されていると、.htaccess ファイルに書くこともできます):
    

    
    
      Options +Includes
    
    

    
    互換性を保つために、server-parsed
    ハンドラ も INCLUDES フィルタを
    有効にします。MIME タイプ text/x-server-parsed-html や
    text/x-server-parsed-html3 のドキュメントに対しても
    Apache は INCLUDES フィルタを有効にします (出力されるものは
    MIME タイプ text/html になります)。

    基本要素
    
    
    ドキュメントは、SGML のコメントとして特別なコマンドが埋め込まれた
    HTML ドキュメントとしてパースされます。コマンドの構文は次のように
    なっています:
    

    
    
      <!--#element attribute=value
      attribute=value ... -->
    
    

    
    値 (訳注: value) は二重引用符で囲むのが一般的ですが、
    シングルクオート (') とバッククオート (`) も使用できます。
    多くのコマンドは属性-値 (訳注: attribute-value) の組を一つだけ指定できます。
    コメントの終わり (-->)
    の前には、SSI の句の一部だと解釈されないようにするために空白を
    入れてください。最初の <!--# はまとめて一つの
    句で、空白をふくんではいけないこと注意してください。

    mod_cgi で提供されていて、このモジュールが
    ロードされる場合にのみ利用可能となります。
    

    
    config 要素
    
      
    次のコマンドは解析の様々な側面を制御します。属性は次の通りです。
    

      
    
      
    echomsg (Apache 2.1 以降)
    
      
    指定される値は、echo
      要素が未定義の変数をエコーしようとした際に、
      クライアントに送られるメッセージになります。
      SSIUndefinedEcho 
      ディレクティブを上書きします。
    

      
    errmsg
    
      
    この値が、ドキュメントの解析中にエラーが発生した時に
      クライアントに送信されるメッセージになります。
      SSIErrorMsg
      ディレクティブを上書きします。
    

      
    sizefmt
    
      
    この値は、ファイルのサイズを表示する際に使用する
      フォーマットを設定します。値は バイトカウントの
      bytesか、Kb や Mb を優先的に使用する
      abbrec (例えば 1024 バイトは "1K" と表示されます)
      です。
    

      
    timefmt
    
      
    この値は strftime(3) ライブラリルーチンが
      日時をプリントする際に用いられます。
    
      
    
     

    
    echo 要素
    
      
    このコマンドは以下で定義されている include
      変数 を表示します。変数が設定されていない場合は SSIUndefinedEcho ディレクティブで
      決定される結果となります。日付はその時点での timefmt に従って
      表示されます。属性は次の通りです。
    

      
    
      
    var
    
      
    値は表示する変数の名前です。
    

      
    encoding
    
      
    変数を出力する前に、変数中の特別文字をどのようにエンコードするかを
      指定します。none に設定されていると、エンコードは行なわれません。
      url に設定されていると、URL エンコード (%-エンコードとも
      呼ばれています。これはリンク等の URL の使用に適切です) が
      行なわれます。echo 要素の開始時は、デフォルトは
      entity に設定されています。これはエンティティエンコード
      (段落やテキストなどのブロックレベルの HTML エレメントのコンテキストに
      適しています) を行ないます。これは encoding 属性
      を加えることで変更できます。変更は次の encoding 属性か、
      要素の終了まで効力を持ちます。
    

      
    encoding 属性はエンコードの変更をしたい var 
      の前に ある必要があることに注意してください。
      また、ISO-8859-1 エンコーディングで
      定義されている特別な文字だけがエンコードされます。
      別の文字のエンコーディングの場合は、このエンコーディングは
      望みの結果にならないかもしれません。
    

      
    
        クロスサイトスクリプティングの問題を避けるために、
        常にユーザからのデータをエンコードすべきです。
      
    
      
    
      
    
     

    
    exec 要素
    
      
    exec コマンドは指定されたシェルコマンドや CGI スクリプトを
      実行します。mod_cgi がサーバに組み込まれているいなければ
      なりません。Option 
      IncludesNOEXEC はこのコマンドを無効にします。
      使用可能な属性は次の通りです。
    

      
    
      
    cgi
    
      
    値は (%-エンコードされた) URL を指定します。パスが
      スラッシュ (/) で始まらないときは、ドキュメントからの
      相対パスとして扱われます。このパスで参照されているドキュメントは
      サーバが CGI スクリプトとして扱っていなくても CGI スクリプトとして
      起動されます。ただし、スクリプトのあるディレクトリでは
      (ScriptAlias
      や Option ExecCGI
      によって) CGI スクリプトの使用が許可されている必要があります。
    

      
    CGI スクリプトには、クライアントからの元々のリクエストの
      PATH_INFO とクエリー文字列 (QUERY_STRING) が渡されます。
      これらは URL パスとして特定できないものです。
      スクリプトは標準 CGI 環境に加えて、include 変数を
      使用することができます。
    

      
    例
    
        <!--#exec cgi="/cgi-bin/example.cgi" -->
      
    

      
    スクリプトが、出力の代わりに Location: ヘッダを返すと、
      HTML のアンカー (訳注: リンク) に変換されます。
    

      
    exec cgi よりも、
      include virtual
      の方を使うようにしてください。特に、CGI への追加の引数を
      クエリー文字列を使って渡すことは exec cgi は
      できませんが、include virtual は以下のようにして
      可能です。
    

      
    
        <!--#include virtual="/cgi-bin/example.cgi?argument=value" -->
      
    
      
    

      
    cmd
    
      
    サーバは指定された文字列を /bin/sh を使って
      実行します。コマンドは通常の CGI 変数に加えて include 変数も使うことができます。
    

      
    ほとんどの場合、#include 
      virtual を使う方が #exec cgi や #exec
      cmd を使うよりも良いです。前者 (#include virtual)
      は標準の Apache のサブリクエスト機構を使ってファイルやスクリプトの
      出力を取り込みます。
      こちらの方がよくテストされメンテナンスされた方法です。
    

      
    さらに、Win32 のようないくつかのプラットフォームや、suexec を使っている unix では、
      exec ディレクティブのコマンドに
      引数を渡したり、コマンドに空白を入れることはできません。
      ですから、以下のものは unix の suexec でない設定では動作しますが、
      Win32 や suexec を使っている unix では期待した結果にはなりません:
    

      
    
        <!--#exec cmd="perl /path/to/perlscript arg1 arg2" -->
      
    
      
    
      
    
     

    
    fsize 要素
    
      
    このコマンドは指定されたファイルの大きさを sizefmt の
      書式指定に基づいて出力します。属性は次の通りです。
    

      
    
      
    file
    
      
    値は解析されているドキュメントの存在するディレクトリからの
      相対パスです。
    

      
    virtual
    
      
     値は (% エンコードされた) URL-path です。スラッシュ (/) で
      始まらないときはドキュメントからの相対パスとして扱われます。
      CGI の出力のサイズはプリントされません。CGI
      スクリプト自体のサイズがプリントされることに注意してください。
    
      
    
     

    
    flastmod 要素
    
      
    このコマンドは指定されたファイルの最終修正時刻を
      timefmt 書式指定に従って表示します。
      指定可能な属性は fsize コマンドと同じです。
    
     

    
    include 要素
    
      
    このコマンドは別の文書やファイルのテキストを解析しているファイルに
      挿入します。挿入されるファイルはアクセス制御の管理下にあります。
      解析しているファイルの存在するディレクトリに
      Option IncludesNOEXEC
      が設定されている場合、text MIME タイプ
      (text/plain, text/html 等) 
      のドキュメントのみインクルードが行なわれます。
      その他の場合は、クエリー文字列も含め、コマンドで指定された
      完全な URL を使って普通に CGI スクリプトが呼び出されます。
    

      
    属性が文書の位置を指定します。include コマンドに与えられたそれぞれの
      属性に対して挿入作業が行なわれます。有効な属性は次の通りです。
    

      
    
      
    file
    
      
    値は解析されているドキュメントの存在するディレクトリからの
      相対パスです。
      ../ を含んでいたり、絶対パスを指定したりはできません。
      ですから、ドキュメントルートの外にあるファイルや、ディレクトリ構造で
      上位にあるファイルを挿入することはできません。
      常にこの属性よりは、virtual 属性を使うようにしてください。
      
    

      
    virtual
    
      
    値は解析されているドキュメントからの (% エンコードされた) URL
      です。URL にはスキームやホスト名を含めることはできません。パスと、
      もしあればクエリー文字列を指定できるだけです。スラッシュ (/) から
      始まらない場合は、ドキュメントからの相対パスとして扱われます。
    

      
    URL は属性から作られ、その URL をクライアントがアクセスしたときに
      出力される内容が解析後の出力に含められます。ですから、挿入される
      ファイルは入れ子構造にすることができます。
    

      
    指定された URL が CGI プログラムであった場合は、
      プログラムが実行され、その出力が解析しているファイル中の
      ディレクティブがあった位置に挿入されます。CGI の url に
      クエリー URL を入れることもできます。
    

      
    
        <!--#include virtual="/cgi-bin/example.cgi?argument=value" -->
      
    

      
    HTML ドキュメントに CGI プログラムの出力を含める方法としては、
      include virtual の方が exec cgi よりも
      好ましい方法です。
    

      
    KeptBodySize
      ディレクティブが設定されていて、かつ、この対象ファイルが
      (訳注: POST リクエストを)受け入れできるなら、
      POST リクエストを受け取ってサブリクエストを発行する際にも
      POST リクエストが渡されます。
      このディレクティブが設定されていない場合は、
      サブリクエストは GET リクエストとして処理されます。
    

      
    
      
    
     

    
    printenv 要素
    
      
    これは、存在するすべての変数とその値を表示します。Apache 1.3.12 から、
      特別な文字は出力される前にエンティティエンコード (詳細は echo 要素を参照)
      されるようになりました。属性はありません。
    

      
    例
    
        <!--#printenv -->
      
    
     

    
    set 要素
    
      
    これは変数の値を設定します。属性は次の通りです。
    

      
    
      
    var
    
      
    設定する変数の名前。
    

      
    value
          
      
    変数に設定する値。
    
      
    

      
    例
    
        <!--#set var="category" value="help" -->
      
    
     

    top
    

    

    Include 変数
    
    

    
    標準 CGI 環境の変数に加えて、echo コマンドや、
    if や elif, それにドキュメントから呼び出される
    すべてのプログラムから使用できる変数があります。
    

    
    
      
    DATE_GMT
    
      
    グリニッジ標準時による現在時刻。
    

      
    DATE_LOCAL
    
      
    ローカルの標準時による現在時刻。
    

      
    DOCUMENT_NAME
    
      
    ユーザがリクエストした (ディレクトリを除いた) ファイル名。
    

      
    DOCUMENT_URI
    
      
    ユーザがリクエストした (% エンコードされた) URL-path。
      挿入ファイルが入れ子になっている場合は、解析されている
     ドキュメントの URL ではないことに注意してください。
    

      
    LAST_MODIFIED
    
      
    ユーザがリクエストしたドキュメントの最終修正時刻。
    

      
    QUERY_STRING_UNESCAPED
    
      
    クエリー文字列がある場合、この変数には (%-デコードされた)
      クエリー文字列が代入されていて、shell で使用できるように
      エスケープされています (&
      といった特殊文字にはバックスラッシュが直前に置かれます)。
    
    
    

    top
    

    

    変数置換
    

    
    変数置換はたいていの場合 SSI ディレクティブの引数として妥当な場所にある
    引用符で囲まれた文字列中で行なわれます。これに該当するものには、
    config,
    exec, flastmod, fsize,
    include, echo, set の
    各ディレクティブと、条件分岐用のオペレータへの引数があります。
    ドル記号はバックスラッシュを使うことで使うことができます:
    

    
    
      <!--#if expr="$a = \$test" -->
    
    

    
    変数名としてみなされる文字列の中で変数への参照を置換する必要があるときは、
    シェルでの変数置換のように、中括弧で括ることで区別することができます:
    

    
    
      <!--#set var="Zed" value="${REMOTE_HOST}_${REQUEST_METHOD}" -->
    
    

    
    この例では、REMOTE_HOST が
    "X" で REQUEST_METHOD が
    "Y" のときに変数 Zed を "X_Y"
    に設定します。
    

    
    以下の例では、DOCUMENT_URI が /foo/file.html
    のときに "in foo" を、/bar/file.html のときに "in bar" を、
    どちらでもないときには "in neither" を表示します。
    

    
    
      <!--#if expr='"$DOCUMENT_URI" = "/foo/file.html"' -->
    
      
        in foo
    
          
      <!--#elif expr='"$DOCUMENT_URI" = "/bar/file.html"' -->
    
      
        in bar
    
          
      <!--#else -->
    
      
        in neither
    
          
      <!--#endif -->
    
    

    top
    

    

    フロー制御要素
    
    

    
    基本的なフローコントロール要素は次の通りです。
    

    
    
      <!--#if expr="test_condition" -->
    
      <!--#elif expr="test_condition" -->
    
      <!--#else -->
    
      <!--#endif -->
    
    

    
    if 要素はプログラミング言語の
    if 文と同じように動作します。条件が評価され、結果が真であれば次の
    elif か else か endif
    要素までの文字列が出力に挿入されます。
    

    
    elif や else 文は test_condition 
    が偽のときにテキストを出力に挿入するために使われます。
    これらの要素はあってもなくても構いません。
    

    
    endif 要素は if
    要素を終了させます。この要素は必須です。
    

    
    test_condition は以下のどれかです:
    

    
    
      
    string
    
      
    string が空でない場合に真です
    

      
    -A string
    
      
    (訳注: httpd の)設定を検査して、
      文字列で指定した URL にアクセスできる場合 true で、
      そうでなければ false になります。
      SSIAccessEnable が有効のときにのみ
      この検査は行われます。
      承認されていないユーザからは隠しておきたい URL についての情報、
      たとえば URL へのリンクなどがある場合に、便利です。
      検査では URL へアクセスできるかの権限のみが行われ、URL
      が存在するかどうかについては検査されないことに注意してください。
    

      
    Example
    
        <!--#if expr="-A /private" -->
    
        
          Click <a href="/private">here</a> to access private
          information.
    
            
        <!--#endif -->
      
    
      
    

      
    string1 = string2
    
      string1 == string2
    
      string1 != string2
    

      
    string1 と string2 を比較します。
      string2 が /string/
      という形式であれば、正規表現として比較されます。正規表現は
      PCRE エンジンで実装されていて、
      perl 5 と同じ構文を使用します。
      == は単に = の別名で、まったく同じ動作を
      します。
    

      
    正のマッチング (= または ==) の場合は、
      正規表現でグループ分けされたパーツをキャプチャすることができます。
      キャプチャされた部分は特殊変数 $1 .. $9
      に格納されます。
    

      
    例
    
        <!--#if expr="$QUERY_STRING = /^sid=([a-zA-Z0-9]+)/" -->
    
        
          <!--#set var="session" value="$1" -->
    
            
        <!--#endif -->
      
    
      
    

      
    string1 < string2
    
       string1 <= string2
    
       string1 > string2
    
       string1 >= string2
    

      
    string1 と string2 を比較します。
      文字列として比較される (strcmp(3) を使用)
      ことに注意してください。ですから、文字列 "100" は "20" 
      よりも小さいことになります。
    

      
    ( test_condition )
    
      
    test_condition が真のとき、真
    

      
    ! test_condition
    
      
    test_condition が偽のとき、真
    

      
    test_condition1 &&
        test_condition2
    
      
    test_condition1 かつ
      test_condition2 が真のとき、真
    

      
    test_condition1 ||
        test_condition2
    
      
    test_condition1 または
      test_condition2 が真のとき、真
    
    
    

    
    "=" と "!=" の方が "&&" より
    きつく束縛します。"!" の束縛が一番きつくなっています。
    ですから以下の二つは等価です:
    

    
    
      <!--#if expr="$a = test1 && $b = test2" -->
    
      <!--#if expr="($a = test1) && ($b = test2)" -->
    
    

    
    真偽値オペレータ && と ||
    は同じ優先度です。
    これらのオペレータで一方により強い優先度をつけたい場合には、
    括弧を使う必要があります。
    

    
    変数やオペレータとして認識されないものはすべて文字列として
    扱われます。文字列は引用符で囲むこともできます: 'string'
    のように。引用符で囲まれていない文字列には空白 (スペースとタブ)
    を含めることはできません。それらは変数などの句を分離するために
    使われているからです。複数の文字列が続いているときは、
    空白を間に入れて一つにくっつけられます。ですから、
    

    
    string1    string2 は string1 string2 になります。
    
      
    
      また、
    
      
    
      'string1    string2' は string1    string2
      になります。
    

    
    真偽値表現の最適化
    
      
    式がもっと複雑になり、処理の速度低下が顕著になった場合は、
      評価ルールに従って最適化してみると良いでしょう。
    
      
      
      
    • 評価は左から右に向かって行われます。
      • 
      
    • 二値真偽値オペレータ (&& と ||)
          は、出来る限り短絡評価されます。つまり結果として上記のルールは、
          mod_include が左の評価式を評価します。
          左側で結果を十分決定できる場合は、評価はそこで停止します。
          そうでない場合は右側を評価して、左と右の両方から結果を計算します。
      • 
      
    • 短絡評価は評価の対象に正規表現が含まれる場合、オフになります。
          後方参照する変数 ($1 .. $9) 
          を埋めるために、実際に評価する必要があるからです。
      • 
      
    
      
    特定の式がどのように扱われるかを知りたい場合は、
      -DDEBUG_INCLUDE コンパイラオプションを付けて
      mod_include をリコンパイルすると良いでしょう。
      これにより、全てのパースされた式に対して、字句解析情報、
      パースツリーと、
      それがどのようにクライアントに送られた出力まで評価されたかを
      挿入します。
    
    
    
 
    
    正規表現内での / のエスケープ
    
    
    正規表現内でデリミタとして扱いたくない / があれば、それらは全て
    エスケープしなければなりません。
    正規表現の意味がどうであろうとエスケープは必要です。

    このディレクティブは DATE 環境変数を echo して日付を現す文字列が
    表示されるときの書式を変更します。formatstring は
    C 標準ライブラリの strftime(3) と同じ形式です。
    

    
    このディレクティブは <!--#config
    timefmt=formatstring --> 要素と同じ効果になります。
    

    
    例
    
      SSITimeFormat "%R, %B %d, %Y"
    
    

    
    上のディレクティブでは、日付は "22:26, June 14, 2002" という
    形式で表示されます。

    XBitHack ディレクティブは通常の HTML
    ドキュメントの解析を制御します。このディレクティブは MIME タイプ
    text/html と関連付けられているファイルにのみ影響します。
    XBitHack は以下の値をとることができます。
    

    
    
      
    off
    
      
    実行可能ファイルに対して特別な扱いをしません。
    

      
    on
    
      
    ユーザの実行ビットが設定されている text/html
      ファイルは全てサーバで解析する html ドキュメントとして扱われます。
    

      
    full
    
      
    on と同様ですが、グループ実行ビットもテストします。
      もしそれが設定されていれば、返されるファイルの Last-modified の
      日付をファイルの最終修正時刻にします。それが設定されていないときは、
      last-modified の日付は送られません。このビットを設定すると、
      クライアントやプロキシがリクエストをキャッシュできるようになります。

      
    注意 他の CGI を #include
      するかもしれないものや、各アクセスに対して違う出力を生成する
      (もしくは後のリクエストで変わるかもしれないもの)
      すべての SSI スクリプトに対してグループ実行ビットが
      設定されていないことを確認できない場合は、full は使わない方が良い
      でしょう。

    Identificateur de Module:authz_groupfile_module

    Compatibilité:Disponible depuis les versions 2.1 et supérieures
d'Apache
    

    Sommaire
    

    
    Ce module permet d'autoriser ou d'interdire l'accès à
certaines zones du site web aux utilisateurs authentifiés en
fonction de leur appartenance à un groupe spécifié. Le module
mod_authz_dbm fournit une fonctionnalité similaire.

    Les directives Require
    

    
    Les directives Require d'Apache permettent,
    au cours de la phase d'autorisation, de s'assurer qu'un utilisateur
    est bien autorisé à accéder à une ressource. mod_authz_groupfile ajoute
    les types d'autorisation group et file-group.
    
    

    
    A partir de la version 2.4.8, les directives require groupfile
    supportent les expressions.
    


    Require group
    

    
    Cette directive permet de spécifier à quel groupe un utilisateur
    doit appartenir pour obtenir l'autorisation d'accès.
    

    
    Require group admin
    





    Require file-group
    

    
    Lorsque cette directive est définie, Les permissions système du fichier
    auquel on veut accéder sont vérifiées. L'utilisateur doit être un membre d'un
    groupe de même nom que le groupe qui possède le fichier. Voir
    mod_authz_owner pour plus de détails.
    

    
    Require file-group

    Directive AuthGroupFile
    

    

    Description:Définit le nom d'un fichier texte contenant la liste des
groupes d'utilisateurs permettant de définir les autorisations des
utilisateurs
    

    Syntaxe:AuthGroupFile chemin-fichier
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Base
    

    Module:mod_authz_groupfile
    

    
    
    La directive AuthGroupFile permet de définir
le nom d'un fichier texte contenant la liste des groupes d'utilisateurs.
L'appartenance d'un utilisateur à tel ou tel groupe pourra dès lors être utilisée
pour définir les permissions d'accès de l'utilisateur.
chemin-fichier est le chemin du fichier de groupes. S'il n'est
pas absolu, ce chemin est considéré comme relatif au répertoire défini par
la directive ServerRoot.
    

    
    Chaque ligne du fichier de groupes contient un nom de groupe
suivi du caractère ':' et des noms des utilisateurs membres du groupe
séparés par des espaces.
    

    
    Exemple :
    
      mon-groupe : bob joe anne
    
    

    
    Notez que la recherche dans de grands fichiers textes est
très inefficace ; la directive AuthDBMGroupFile fournit de bien meilleures
    performances.
    

    
    Sécurité
    
      
    Le fichier AuthGroupFile ne doit pas
être stocké dans l'arborescence des documents du site web ; ne le placez
surtout pas dans le répertoire qu'il protège, faute de quoi les
clients pourraient le télécharger.

    Module Apache mod_usertrack
    

    

    Langues Disponibles:  en  |

    Description:
Journalisation Clickstream des liens parcourus par un
utilisateur sur un site

    

    Statut:Extension
    

    Identificateur de Module:usertrack_module
    

    Fichier Source:mod_usertrack.c
    

    Sommaire
    

    
    Ce module permet de suivre le parcours d'un utilisateur à travers
    votre site web en faisant appel aux cookies de navigateur.
    

    


    top
    

    

    Journalisation
    


    
    mod_usertrack définit un cookie qui peut être
    journalisé via les formats configurables du module
    mod_log_config :
    

    
    LogFormat "%{Apache}n %r %t" usertrack
CustomLog "logs/clickstream.log" usertrack

    Directive CookieDomain
    

    

    Description:Le domaine auquel le cookie traceur
s'applique
    

    Syntaxe:CookieDomain domaine
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_usertrack
    

    

    
    Cette directive permet de définir le domaine auquel le cookie
    traceur s'applique. Si elle n'est pas présente, aucun domaine n'est
    inclus dans le champ d'en-tête cookie.
    

    
    La chaîne dommaine doit commencer par un point,
    et doit comporter au moins un point entouré
    d'autres caractères. Par exemple, .example.com est
    une chaîne valide, mais www.example.com et
    .com ne le sont pas.
    

    
    La plupart des navigateurs utilisés actuellement n'autorisent
    pas la définition de cookies pour un domaine racine de deux niveaux,
    tel que .co.uk, bien qu'un tel domaine remplisse les
    conditions de validité décrites ci-dessus.
    

    Ces domaines sont équivalents à des domaines racines comme
    .com, et autoriser de tels cookies peut constituer un
    risque en matière de sécurité. Ainsi, si vous vous situez sous un
    domaine racine de deux niveaux, vous devez encore utiliser votre
    domaine véritable, comme vous le feriez avec tout autre domaine
    racine (par exemple .example.co.uk).
    
    

    
    CookieDomain .example.com

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_usertrack
    

    
    
    Lorsqu'elle est utilisée, cette directive définit une durée avant
    l'expiration du cookie généré par le module usertrack. La
    durée peut être spécifiée sous la forme d'un nombre de
    secondes, ou sous une forme du
    style "2 weeks 3 days 7 hours". les termes valides sont : years,
    months, weeks, days, hours, minutes et seconds. Si la durée est
    spécifiée dans un format autre qu'un nombre de secondes, elle doit
    être entourée de guillemets.
    

    
    Si cette directive est absente, la durée de vie des cookies est
    limitée à la session actuelle du navigateur.
    

    
    CookieExpires "3 weeks"

    Module:mod_usertrack
    

    Compatibilité:Disponible à partir de la version 2.4.42 du serveur HTTP Apache
    

    
    
    Lorsqu'elle est définie à 'ON', cette directive ajoute l'attribut 'HTTPOnly'
    au cookie de traçage. Cet attribut indique aux navigateurs qu'ils doivent
    bloquer javascript au cours de la lecture de la valeur du cookie.
    


    

    top
    

    Directive CookieName
    

    

    Description:Nom du cookie traceur
    

    Syntaxe:CookieName symbole
    

    Défaut:CookieName Apache
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_usertrack
    

    
    
    Cette directive vous permet de modifier le nom du cookie que ce
    module utilise pour sa journalisation. Le nom par défaut du cookie
    est "Apache".
    

    
    Vous devez spécifier un nom de cookie valide ; les résultats sont
    imprévisibles si vous utilisez un nom contenant des caractères
    inhabituels. Les caractères valides font partie des intervales A-Z,
    a-z, 0-9, "_", et "-".
    

    
    CookieName clicktrack

    Défaut:unset
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_usertrack
    

    Compatibilité:Disponible à partir de la version 2.4.42 du serveur HTTP Apache
    

    
    
    Lorsque cette directive est définie à 'None', 'Lax', ou 'Strict',
    l'attribut 'SameSite' est ajouté au cookie de traçage avec la valeur
    correspondante. Cet attribut indique aux navigateurs de quelle manière ils
    doivent traiter le cookie lorsqu'il est demandé dans un contexte cross-site.
    

     
    
        
    'None' définit l'attribut 'SameSite' à 'None', ce qui correspond à la
	configuration la plus permissive. Pour ne pas ajouter cet attribut au
	cookie, il est donc préférable de ne pas définir du tout cette directive.

    Directive CookieSecure
    

    

    Description:Ajoute l'attribut 'Secure' au cookie
    

    Syntaxe:CookieSecure on|off
    

    Défaut:CookieSecure off
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_usertrack
    

    Compatibilité:Disponible à partir de la version 2.4.42 du serveur HTTP Apache
    

    
    
    Lorsqu'elle est définie à 'ON', cette directive ajoute l'attribut 'Secure'
    au cookie de traçage. Cet attribut indique aux navigateurs qu'il ne doivent
    transmettre le cookie que via HTTPS.

    Directive CookieStyle
    

    

    Description:Format du champ d'en-tête cookie

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_usertrack
    

    
    
    Cette directive permet de contrôler le format du champ d'en-tête
    cookie. Les trois formats autorisés sont :
    

    
      
      
    • Netscape : il s'agit du format original, mais
      est désormais obsolète. C'est le format par défaut et il
      correspond à la syntaxe historique utilisée par Apache.
      • 

      
    • Cookie ou RFC2109 : c'est la
      syntaxe qui remplace la syntaxe Netscape.
      • 

      
    • Cookie2 ou RFC2965 : c'est
      la syntaxe de cookie la plus actuelle.
      • 
    
    

    
    Tous les clients ne supportent pas l'ensemble de ces formats,
    mais il est conseillé d'utiliser le plus récent qui sera en général
    supporté par le navigateur utilisé par vos utilisateurs. A l'heure où ce
    document est écrit, la plupart des navigateurs supportent ces trois
    formats, Cookie2 étant le format recommandé.

    Lorsque le module mod_usertrack est chargé, et
    si CookieTracking on est définie, Apache enverra un
    cookie traceur pour toute nouvelle requête. Cette directive peut
    être utilisée pour activer ou désactiver ce comportement pour un
    serveur virtuel ou un répertoire. Par défaut, l'activation de
    mod_usertrack ne suffit pas pour
    activer les cookies.

    Apache Module mod_substitute
    

    

    Available Languages:  en  |

    Description:Perform search and replace operations on response bodies
    

    Status:Extension
    

    Module Identifier:substitute_module
    

    Source File:mod_substitute.c
    

    Compatibility:Available in Apache HTTP Server 2.2.7 and later
    

    Summary
    

    
    mod_substitute provides a mechanism to perform
    both regular expression and fixed string substitutions on
    response bodies.
    

    



    top
    

    Substitute Directive
    

    

    Description:Pattern to filter the response content
    

    Syntax:Substitute s/pattern/substitution/[infq]
    

    Context:directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_substitute
    

    
    
    The Substitute directive specifies a
    search and replace pattern to apply to the response body.
    

    
    The meaning of the pattern can be modified by using any
    combination of these flags:
    

    
    
        
    i
    
        
    Perform a case-insensitive match.
    
        
    n
    
        
    By default the pattern is treated as a regular expression.
        Using the n flag forces the pattern to be treated
        as a fixed string.
    
        
    f
    
        
    The f flag causes mod_substitute to flatten the
        result of a substitution allowing for later substitutions to
        take place on the boundary of this one. This is the default.
    
        
    q
    
        
    The q flag causes mod_substitute to not
        flatten the buckets after each substitution. This can
        result in much faster response and a decrease in memory
        utilization, but should only be used if there is no possibility
        that the result of one substitution will ever match a pattern
        or regex of a subsequent one.
    
    
    

    
    The substitution may contain literal text and regular
    expression backreferences
    

    
    Example
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    Substitute "s/foo/bar/ni"
</Location>
    

    

    
    The character which is used to separate (or "delimit") the
    various parts of the substitution string is referred to as the
    "delimiter", and it is most common to use a slash for this
    purpose.
    

    
    If either the pattern or the substitution contain a slash
    character then an alternative delimiter may be used to make the
    directive more readable:
    

    
    Example of using an alternate delimiter
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    Substitute "s|<BR */?>|<br />|i"
</Location>
    

    

    
    Backreferences can be used in the comparison and in the substitution,
    when regular expressions are used, as illustrated in the following example: 
    
    
    Example of using backreferences and captures
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    # "foo=k,bar=k" -> "foo/bar=k"
    Substitute "s|foo=(\w+),bar=\1|foo/bar=$1|"
</Location>
    

    

    
    A common use scenario for mod_substitute is the
    situation in which a front-end server proxies requests to a back-end
    server which returns HTML with hard-coded embedded URLs that refer
    to the back-end server. These URLs don't work for the end-user,
    since the back-end server is unreachable.
    

    
    In this case, mod_substitute can be used to rewrite
    those URLs into something that will work from the front end:
    

    
    Rewriting URLs embedded in proxied content
    ProxyPass        "/blog/" "http://internal.blog.example.com/"
ProxyPassReverse "/blog/" "http://internal.blog.example.com/"

Substitute "s|http://internal.blog.example.com/|http://www.example.com/blog/|i"
    

    

    
    ProxyPassReverse
    modifies any Location (redirect) headers that are sent
    by the back-end server, and, in this example,
    Substitute takes care of the rest of the problem by
    fixing up the HTML response as well.

    SubstituteInheritBefore Directive
    

    

    Description:Change the merge order of inherited patterns
    

    Syntax:SubstituteInheritBefore on|off
    

    Default:SubstituteInheritBefore off
    

    Context:directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_substitute
    

    Compatibility:Available in httpd 2.4.17 and later
    

    
    
    Whether to apply the inherited Substitute
    patterns first (on), or after the ones of the current
    context (off).
    SubstituteInheritBefore is itself inherited,
    hence contexts that inherit it (those that don't specify their own
    SubstituteInheritBefore value) will apply the
    closest defined merge order.

    SubstituteMaxLineLength Directive
    

    

    Description:Set the maximum line size
    

    Syntax:SubstituteMaxLineLength bytes(b|B|k|K|m|M|g|G)
    

    Default:SubstituteMaxLineLength 1m
    

    Context:directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_substitute
    

    Compatibility:Available in httpd 2.4.11 and later
    

    
    
    The maximum line size handled by mod_substitute
    is limited to restrict memory use. The limit can be configured
    using SubstituteMaxLineLength.
    The value can be given as the number of bytes and can be suffixed
    with a single letter b, B, k,
    K, m, M, g,
    G to provide the size in bytes, kilobytes, megabytes
    or gigabytes respectively.
    

    
    Example
    <Location "/">
    AddOutputFilterByType SUBSTITUTE text/html
    SubstituteMaxLineLength 10m
    Substitute "s/foo/bar/ni"
</Location>

    Sommaire
    

    
    Ce module possède deux directives. La directive Action vous permet de lancer
    l'exécution de scripts CGI chaque fois qu'un fichier possédant un
    certain type de contenu MIME
    fait l'objet d'une requête. La directive Script vous permet de lancer
    l'exécution de scripts CGI chaque fois que la requête utilise une
    méthode particulière. Ceci facilite grandement l'exécution de
    scripts qui traitent des fichiers.

    Directive Action
    

    

    Description:Active un script CGI pour un gestionnaire ou un type de
contenu particulier
    

    Syntaxe:Action type d'action script cgi

    Compatibilité:Le modificateur virtual et le passage de
gestionnaire ont été introduits dans Apache 2.1
    

    
    
    Cette directive ajoute une action qui va activer script
    cgi lorsque type d'action est déclenché par la
    requête. script cgi est un chemin URL vers une ressource
    qui a été désignée comme script CGI à l'aide des directives
    ScriptAlias ou AddHandler. type d'action
    peut être soit un gestionnaire, soit
    un type de contenu MIME. L'URL
    et le chemin du document correspondant sont envoyés en utilisant
    les variables d'environnement CGI standards PATH_INFO
    et PATH_TRANSLATED. Le gestionnaire utilisé pour cette
    requête particulière est transmis à l'aide de la variable
    REDIRECT_HANDLER.
    

    
    Exemple : type MIME
    # Requests for files of a particular MIME content type:
Action image/gif /cgi-bin/images.cgi
    

    

    
    Dans cet exemple, les requêtes pour des fichiers possédant
    le type de contenu MIME image/gif seront traitées par
    le script CGI /cgi-bin/images.cgi.
    

    
    Example: File extension
    # Files of a particular file extension
AddHandler my-file-type .xyz
Action my-file-type "/cgi-bin/program.cgi"
    

    
    
    Dans cet exemple, les requêtes pour des fichiers possédant
    l'extension .xyz seront traitées par
    le script CGI /cgi-bin/programme.cgi.
    

    
    Le modificateur optionnel virtual permet de
    désactiver la vérification de l'existence du fichier demandé. Ceci
    peut s'avérer utile, par exemple, si vous voulez utiliser la
    directive Action pour des localisations
    virtuelles.
    

    
    <Location "/news">
    SetHandler news-handler
    Action news-handler "/cgi-bin/news.cgi" virtual
</Location>

    Directive Script
    

    

    Description:Active un script CGI dans le cas d'une méthode de requête
particulière.
    

    Syntaxe:Script méthode script cgi
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_actions
    

    
    
    Cette directive ajoute une action qui va activer script
    cgi lorsqu'un fichier est demandé en utilisant la méthode
    méthode. script cgi est le chemin URL d'une
    ressource qui a été désignée comme script CGI en utilisant les
    directives ScriptAlias ou AddHandler. L'URL et le chemin du
    document demandé sont envoyés en utilisant les variables
    d'environnement CGI standards PATH_INFO et
    PATH_TRANSLATED.
    

    
    
      Tous les noms de méthode peuvent être utilisés. Les noms
      de méthode sont sensibles à la casse, si bien que
      Script PUT et Script put ont des effets
      totalement différents.
    
    

    
    Notez que la commande Script ne définit
    que des actions par défaut. Si un script CGI est appelé, ou toute
    autre ressource capable de gérer la méthode de la requête en
    interne, il agira en conséquence. Notez aussi que
    Script avec une méthode GET ne
    sera appelé que si la requête possède des arguments (par exemple
    foo.html?hi). Dans le cas contraire, la requête sera traitée
    normalement.
    

    
    # All GET requests go here
Script GET "/cgi-bin/search"

# A CGI PUT handler
Script PUT "/~bob/put.cgi"

    Description:Group authorizations based on host (name or IP
address)
    

    Status:Extension
    

    Module Identifier:access_compat_module
    

    Source File:mod_access_compat.c
    

    Compatibility:Available in Apache HTTP Server 2.3 as a compatibility module with
previous versions of Apache httpd 2.x.  The directives provided by this module
have been deprecated by the new authz refactoring.  Please see
mod_authz_host
    

    Summary
    

    
    The directives provided by mod_access_compat are
    used in <Directory>,
    <Files>, and
    <Location> sections
    as well as .htaccess
     files to control access to particular parts of the server.
    Access can be controlled based on the client hostname, IP address, or
    other characteristics of the client request, as captured in environment variables. The Allow and Deny directives are used to
    specify which clients are or are not allowed access to the server,
    while the Order
    directive sets the default access state, and configures how the
    Allow and Deny directives interact with each
    other.
    

    
    Both host-based access restrictions and password-based
    authentication may be implemented simultaneously. In that case,
    the Satisfy directive is used
    to determine how the two sets of restrictions interact.
    

    
    Note
    
      
    The directives provided by mod_access_compat have
      been deprecated by mod_authz_host. 
      Mixing old directives like Order, Allow or Deny with new ones like
      Require is technically possible 
      but discouraged. This module was created to support 
      configurations containing only old directives to facilitate the 2.4 upgrade. 
      Please check the upgrading guide for more
      information.
      
    
      
    

    
    In general, access restriction directives apply to all
    access methods (GET, PUT,
    POST, etc). This is the desired behavior in most
    cases. However, it is possible to restrict some methods, while
    leaving other methods unrestricted, by enclosing the directives
    in a <Limit> section.
    

    
     
    Merging of configuration sections
    
      
    When any directive provided by this module is used in a new 
      configuration section, no directives provided by this module are
      inherited from previous configuration sections.
    
    
    


    



    top
    

    Allow Directive
    

    

    Description:Controls which hosts can access an area of the
server
    

    Syntax: Allow from all|host|env=[!]env-variable
[host|env=[!]env-variable] ...
    

    Context:directory, .htaccess
    

    Override:Limit
    

    Status:Extension
    

    Module:mod_access_compat
    

    
    
    The Allow directive affects which hosts can
    access an area of the server. Access can be controlled by
    hostname, IP address, IP address range, or by other
    characteristics of the client request captured in environment
    variables.
    

    
    The first argument to this directive is always
    from. The subsequent arguments can take three
    different forms. If Allow from all is specified, then
    all hosts are allowed access, subject to the configuration of the
    Deny and Order directives as discussed
    below. To allow only particular hosts or groups of hosts to access
    the server, the host can be specified in any of the
    following formats:
    

    
    
      
    A (partial) domain-name
    

      
    
      
    Allow from example.org
Allow from .net example.edu
    

      
    Hosts whose names match, or end in, this string are allowed
      access. Only complete components are matched, so the above
      example will match foo.example.org but it will not
      match fooexample.org. This configuration will cause
      Apache httpd to perform a double DNS lookup on the client IP
      address, regardless of the setting of the HostnameLookups directive.  It will do
      a reverse DNS lookup on the IP address to find the associated
      hostname, and then do a forward lookup on the hostname to assure
      that it matches the original IP address.  Only if the forward
      and reverse DNS are consistent and the hostname matches will
      access be allowed.
    

      
    A full IP address
    

      
    
      
    Allow from 10.1.2.3
Allow from 192.168.1.104 192.168.1.205
    

      
    An IP address of a host allowed access
    

      
    A partial IP address
    

      
    
      
    Allow from 10.1
Allow from 10 172.20 192.168.2
    

      
    The first 1 to 3 bytes of an IP address, for subnet
      restriction.
    

      
    A network/netmask pair
    

      
    
      
    Allow from 10.1.0.0/255.255.0.0
    

      
    A network a.b.c.d, and a netmask w.x.y.z. For more
      fine-grained subnet restriction.
    

      
    A network/nnn CIDR specification
    

      
    
      
    Allow from 10.1.0.0/16
    

      
    Similar to the previous case, except the netmask consists of
      nnn high-order 1 bits.
    
    
    

    
    Note that the last three examples above match exactly the
    same set of hosts.
    

    
    IPv6 addresses and IPv6 subnets can be specified as shown
    below:
    

    
    Allow from 2001:db8::a00:20ff:fea7:ccea
Allow from 2001:db8::a00:20ff:fea7:ccea/10
    


    
    The third format of the arguments to the
    Allow directive allows access to the server
    to be controlled based on the existence of an environment variable. When Allow from
    env=env-variable is specified, then the request is
    allowed access if the environment variable env-variable
    exists. When Allow from env=!env-variable is
    specified, then the request is allowed access if the environment
    variable env-variable doesn't exist.
    The server provides the ability to set environment
    variables in a flexible way based on characteristics of the client
    request using the directives provided by
    mod_setenvif. Therefore, this directive can be
    used to allow access based on such factors as the clients
    User-Agent (browser type), Referer, or
    other HTTP request header fields.
    

    
    SetEnvIf User-Agent ^KnockKnock/2\.0 let_me_in
<Directory "/docroot">
    Order Deny,Allow
    Deny from all
    Allow from env=let_me_in
</Directory>
    


    
    In this case, browsers with a user-agent string beginning
    with KnockKnock/2.0 will be allowed access, and all
    others will be denied.
    

    
     
    Merging of configuration sections
    
      
    When any directive provided by this module is used in a new 
      configuration section, no directives provided by this module are
      inherited from previous configuration sections.
    
    
    



    

    top
    

    Deny Directive
    

    

    Description:Controls which hosts are denied access to the
server
    

    Syntax: Deny from all|host|env=[!]env-variable
[host|env=[!]env-variable] ...
    

    Context:directory, .htaccess
    

    Override:Limit
    

    Status:Extension
    

    Module:mod_access_compat
    

    
    
    This directive allows access to the server to be restricted
    based on hostname, IP address, or environment variables. The
    arguments for the Deny directive are
    identical to the arguments for the Allow directive.
    


    

    top
    

    Order Directive
    

    

    Description:Controls the default access state and the order in which
Allow and Deny are
evaluated.
    

    Syntax: Order ordering
    

    Default:Order Deny,Allow
    

    Context:directory, .htaccess
    

    Override:Limit
    

    Status:Extension
    

    Module:mod_access_compat
    

    

    
    The Order directive, along with the
    Allow and
    Deny directives,
    controls a three-pass access control system. The first pass
    processes either all Allow or all Deny directives, as specified
    by the Order
    directive. The second pass parses the rest of the directives
    (Deny or
    Allow). The third
    pass applies to all requests which do not match either of the first
    two.
    

    
    Note that all Allow and Deny directives are
    processed, unlike a typical firewall, where only the first match is
    used. The last match is effective (also unlike a typical firewall).
    Additionally, the order in which lines appear in the configuration
    files is not significant -- all Allow lines are processed as
    one group, all Deny lines are considered as
    another, and the default state is considered by itself.
    

    
    Ordering is one of:
    

    
    
      
    Allow,Deny
    

      
    First, all Allow directives are
      evaluated; at least one must match, or the request is rejected.
      Next, all Deny
      directives are evaluated. If any matches, the request is rejected.
      Last, any requests which do not match an Allow or a Deny directive are denied
      by default.
    

      
    Deny,Allow
    

      
    First, all Deny directives are
      evaluated; if any match, the request is denied
      unless it also matches an Allow directive. Any
      requests which do not match any Allow or Deny directives are
      permitted.
    

      
    Mutual-failure
    

      
    This order has the same effect as Order
      Allow,Deny and is deprecated in its favor.
    
    
    

    
    Keywords may only be separated by a comma; no whitespace
    is allowed between them.
    

    
    
      
    
        Match
        Allow,Deny result
        Deny,Allow result
      
    
        Match Allow only
        Request allowed
        Request allowed
      
    
        Match Deny only
        Request denied
        Request denied
      
    
        No match
        Default to second directive: Denied
        Default to second directive: Allowed
      
    
        Match both Allow & Deny
        Final match controls: Denied
        Final match controls: Allowed
      
    
    
    

    
    In the following example, all hosts in the example.org domain
    are allowed access; all other hosts are denied access.
    

    
    Order Deny,Allow
Deny from all
Allow from example.org
    


    
    In the next example, all hosts in the example.org domain are
    allowed access, except for the hosts which are in the
    foo.example.org subdomain, who are denied access. All hosts not
    in the example.org domain are denied access because the default
    state is to Deny
    access to the server.
    

    
    Order Allow,Deny
Allow from example.org
Deny from foo.example.org
    


    
    On the other hand, if the Order in the
    last example is changed to Deny,Allow, all hosts will
    be allowed access. This happens because, regardless of the actual
    ordering of the directives in the configuration file, the
    Allow from example.org will be evaluated last and will
    override the Deny from foo.example.org. All hosts not in
    the example.org domain will also be allowed access
    because the default state is Allow.
    

    
    The presence of an Order directive can
    affect access to a part of the server even in the absence of
    accompanying Allow
    and Deny
    directives because of its effect on the default access state. For
    example,
    

    
    <Directory "/www">
    Order Allow,Deny
</Directory>
    


    
    will Deny all access to the /www directory
    because the default access state is set to
    Deny.
    

    
    The Order directive controls the order of access
    directive processing only within each phase of the server's
    configuration processing. This implies, for example, that an
    Allow or Deny directive occurring in a
    <Location> section will
    always be evaluated after an Allow or Deny directive occurring in a
    <Directory> section or
    .htaccess file, regardless of the setting of the
    Order directive. For details on the merging
    of configuration sections, see the documentation on How Directory, Location and Files sections
    work.
    

    
     
    Merging of configuration sections
    
      
    When any directive provided by this module is used in a new 
      configuration section, no directives provided by this module are
      inherited from previous configuration sections.

    Satisfy Directive
    

    

    Description:Interaction between host-level access control and
user authentication
    

    Syntax:Satisfy Any|All
    

    Default:Satisfy All
    

    Context:directory, .htaccess
    

    Override:AuthConfig

later
    

    
    
    Access policy if both Allow and Require used. The parameter can be
    either All or Any. This directive is only
    useful if access to a particular area is being restricted by both
    username/password and client host address. In this case
    the default behavior (All) is to require that the client
    passes the address access restriction and enters a valid
    username and password. With the Any option the client will be
    granted access if they either pass the host restriction or enter a
    valid username and password. This can be used to password restrict
    an area, but to let clients from particular addresses in without
    prompting for a password.
    

    
    For example, if you wanted to let people on your network have
    unrestricted access to a portion of your website, but require that
    people outside of your network provide a password, you could use a
    configuration similar to the following:
    

    
    Require valid-user
Allow from 192.168.1
Satisfy Any
    


    
    
    Another frequent use of the Satisfy directive
    is to relax access restrictions for a subdirectory:
    
    

    
    <Directory "/var/www/private">
    Require valid-user
</Directory>

<Directory "/var/www/private/public">
    Allow from all
    Satisfy Any
</Directory>
    


    
    In the above example, authentication will be required for the
    /var/www/private directory, but will not be required
    for the /var/www/private/public directory.
    

    
    Since version 2.0.51 Satisfy directives can
    be restricted to particular methods by <Limit> and <LimitExcept> sections.
    

    
     
    Merging of configuration sections
    
      
    When any directive provided by this module is used in a new 
      configuration section, no directives provided by this module are
      inherited from previous configuration sections.

    Description:Shared object cache (socache) based storage module for the
HTTP caching filter.
    

    Status:Extension
    

    Module Identifier:cache_socache_module
    

    Source File:mod_cache_socache.c
    

    Summary
    

    
    mod_cache_socache implements a shared object cache
    (socache) based storage manager for mod_cache.
    

    
    The headers and bodies of cached responses are combined, and stored
    underneath a single key in the shared object cache. A
    number of implementations of shared object
    caches are available to choose from.
    

    
    Multiple content negotiated responses can be stored concurrently,
    however the caching of partial content is not yet supported by this
    module.
    

    
    # Turn on caching
CacheSocache shmcb
CacheSocacheMaxSize 102400
<Location "/foo">
    CacheEnable socache
</Location>

# Fall back to the disk cache
CacheSocache shmcb
CacheSocacheMaxSize 102400
<Location "/foo">
    CacheEnable socache
    CacheEnable disk
</Location>
    


    
    Note:
    
      
    mod_cache_socache requires the services of
      mod_cache, which must be loaded before
      mod_cache_socache.

    CacheSocache Directive
    

    

    Description:The shared object cache implementation to use
    

    Syntax:CacheSocache type[:args]
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache_socache
    

    Compatibility:Available in Apache 2.4.5 and later
    

    
    
    The CacheSocache directive defines the name of
    the shared object cache implementation to use, followed by optional
    arguments for that implementation. A number of
    implementations of shared object caches are available to choose
    from.

    CacheSocacheMaxSize Directive
    

    

    Description:The maximum size (in bytes) of an entry to be placed in the
cache
    

    Syntax:CacheSocacheMaxSize bytes
    

    Default:CacheSocacheMaxSize 102400
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache_socache
    

    Compatibility:Available in Apache 2.4.5 and later
    

    
    
    The CacheSocacheMaxSize directive sets the
    maximum size, in bytes, for the combined headers and body of a document
    to be considered for storage in the cache. The larger the headers that
    are stored alongside the body, the smaller the body may be.
    

    
    The mod_cache_socache module will only attempt to
    cache responses that have an explicit content length, or that are small
    enough to be written in one pass. This is done to allow the
    mod_cache_disk module to have an opportunity to cache
    responses larger than those cacheable within
    mod_cache_socache.
    

    
    CacheSocacheMaxSize 102400

    CacheSocacheMaxTime Directive
    

    

    Description:The maximum time (in seconds) for a document to be placed in the
cache
    

    Syntax:CacheSocacheMaxTime seconds
    

    Default:CacheSocacheMaxTime 86400
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache_socache
    

    Compatibility:Available in Apache 2.4.5 and later
    

    
    
    The CacheSocacheMaxTime directive sets the
    maximum freshness lifetime, in seconds, for a document to be stored in
    the cache. This value overrides the freshness lifetime defined for the
    document by the HTTP protocol.
    

    
    CacheSocacheMaxTime 86400

    CacheSocacheMinTime Directive
    

    

    Description:The minimum time (in seconds) for a document to be placed in the
cache
    

    Syntax:CacheSocacheMinTime seconds
    

    Default:CacheSocacheMinTime 600
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache_socache
    

    Compatibility:Available in Apache 2.4.5 and later
    

    
    
    The CacheSocacheMinTime directive sets the
    amount of seconds beyond the freshness lifetime of the response that the
    response should be cached for in the shared object cache. If a response is
    only stored for its freshness lifetime, there will be no opportunity to
    revalidate the response to make it fresh again.
    

    
    CacheSocacheMinTime 600

    CacheSocacheReadSize Directive
    

    

    Description:The minimum size (in bytes) of the document to read and be cached
  before sending the data downstream
    

    Syntax:CacheSocacheReadSize bytes
    

    Default:CacheSocacheReadSize 0
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache_socache
    

    Compatibility:Available in Apache 2.4.5 and later
    

    
    
    The CacheSocacheReadSize directive sets the
    minimum amount of data, in bytes, to be read from the backend before the
    data is sent to the client. The default of zero causes all data read of
    any size to be passed downstream to the client immediately as it arrives.
    Setting this to a higher value causes the disk cache to buffer at least
    this amount before sending the result to the client. This can improve
    performance when caching content from a slow reverse proxy.
    

    
    This directive only takes effect when the data is being saved to the
    cache, as opposed to data being served from the cache.

    CacheSocacheReadTime Directive
    

    

    Description:The minimum time (in milliseconds) that should elapse while reading
  before data is sent downstream
    

    Syntax:CacheSocacheReadTime milliseconds
    

    Default:CacheSocacheReadTime 0
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_cache_socache
    

    Compatibility:Available in Apache 2.4.5 and later
    

    
    
    The CacheSocacheReadTime directive sets the minimum amount
    of elapsed time that should pass before making an attempt to send data
    downstream to the client. During the time period, data will be buffered
    before sending the result to the client. This can improve performance when
    caching content from a reverse proxy.
    

    
    The default of zero disables this option.
    

    
    This directive only takes effect when the data is being saved to the
    cache, as opposed to data being served from the cache. It is recommended
    that this option be used alongside the
    CacheSocacheReadSize directive
    to ensure that the server does not buffer excessively should data arrive faster
    than expected.
    

    
    CacheSocacheReadTime 1000

    Apache HTTP Server Version 2.4
    

    

    <-
    


    

    Apache Module mod_data
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Convert response body into an RFC2397 data URL
    

    Status:Extension
    

    Module Identifier:data_module
    

    Source File:mod_data.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    

    
    This module provides the ability to convert a response into
    an RFC2397 data URL.
    
    

    
    Data URLs can be embedded inline within web pages using something
    like the mod_include module, to remove the need for
    clients to make separate connections to fetch what may potentially be
    many small images. Data URLs may also be included into pages generated
    by scripting languages such as PHP.
    

    
    An example of a data URL
    
        data:image/gif;base64,R0lGODdhMAAwAPAAAAAAAP///ywAAAAAMAAw

    The filter takes no parameters, and can be added to the filter stack
    using the SetOutputFilter directive,
    or any of the directives supported by the mod_filter
    module.

    Serveur HTTP Apache Version 2.4
    

    

    <-
    


    

    Module Apache mod_cgi
    

    

    Langues Disponibles:  en  |

    Description:Exécution des scripts CGI
    

    Statut:Base
    

    Identificateur de Module:cgi_module
    

    Fichier Source:mod_cgi.c
    

    Sommaire
    

    
    Tout fichier pris en compte par le gestionnaire
    cgi-script sera traité en tant que script CGI et
    exécuté par le serveur, sa sortie étant renvoyée au client. Les
    fichiers sont associés à ce gestionnaire soit parce qu'ils possèdent
    un nom contenant une extension définie par la directive AddHandler, soit parce qu'ils se
    situent dans un répertoire défini par une directive ScriptAlias.
    

    
    Comme introduction à l'utilisation des scripts CGI avec Apache,
    voir notre tutoriel Les contenus
    dynamiques avec CGI.
    

    
    Il est recommandé d'utiliser le module mod_cgid
    à la place de mod_cgi lorsqu'on utilise un module MPM
    multi-threadé sous Unix. Vus de l'utilisateur, les deux modules
    sont pratiquement identiques.
    

    
    À des fins de compatibilité ascendante, le gestionnaire
    cgi-script sera aussi activé pour tout fichier possédant le type
    MIME application/x-httpd-cgi. L'utilisation du type
    MIME magic est obsolète.
    

    


    top
    

    

    Les variables d'environnement CGI
    
    
    Le serveur va définir les variables d'environnement CGI comme
    décrit dans la Spécification CGI, de la
    manière suivante :
    

    
    
      
    PATH_INFO
    

      
    Cette variable ne sera pas disponible si la directive
      AcceptPathInfo est
      explicitement définie à off. Par défaut, si la
      directive AcceptPathInfo n'est pas définie,
      mod_cgi acceptera des informations de chemin (en
      ajoutant /infos/chemin après le nom du script dans l'URI), alors
      que le serveur de base retournera une erreur 404 NOT FOUND pour
      les requêtes contenant des informations de chemin supplémentaires.
      Ne pas définir la directive AcceptPathInfo
      a le même effet sur les requêtes avec mod_cgi que
      de la définir à On.
    

      
    REMOTE_HOST
    

      
    Cette variable ne sera définie que si la directive HostnameLookups est définie à
      on (elle est à off par défaut), et si
      une recherche DNS inverse sur l'adresse IP de l'hôte client
      aboutit effectivement à un nom d'hôte.
    

      
    REMOTE_IDENT
    

      
    Cette variable ne sera définie que si la directive IdentityCheck
      est définie à on, et si l'hôte client supporte le
      protocole ident. Notez que l'on ne peut accorder une confiance
      aveugle au contenu de cette variable car il peut être aisément
      falsifié, et si un mandataire s'intercale entre le client et le
      serveur, il est totalement inutilisable.
    

      
    REMOTE_USER
    

      
    Cette variable ne sera définie que si le script CGI fait
      l'objet d'une authentification.
    

    
    
    
    Ce module utilise aussi les fonctions de base ap_add_common_vars
    et ap_add_cgi_vars
    pour ajouter des variables d'environnement comme :
     
       
    
           
    DOCUMENT_ROOT
    

           
    Prend la valeur définie par la directive DocumentRoot.
    

           
    SERVER_NAME
    

           
    Le nom de domaine pleinement qualifié pour la requête considérée
    

           
    SERVER_ADDR
    

           
    L'adresse IP du serveur virtuel qui traite la requête
    

           
    SERVER_ADMIN
    

           
    Prend la valeur définie par la directive ServerAdmin.
    
      
    
    
    Pour une liste exhaustive de ces variables, vous pouvez écrire un script
    CGI basique qui extrait toutes les variables d'environnement passées par
    Apache selon un format adapté.

    Débogage des scripts CGI
    
    
    Le débogage des scripts CGI était difficile par le passé,
    principalement parce qu'il n'était pas possible d'étudier la sortie
    (sortie standard et erreurs) des scripts dont l'exécution échouait.
    Les directives qui suivent permettent une journalisation plus détaillée des
    erreurs.
    

    
    Format du fichier journal CGI
    
      
    Lorsqu'il est configuré, le journal des erreurs CGI enregistre
      la sortie de tout programme CGI dont l'exécution ne s'effectue pas
      correctement. Un script CGI dont l'exécution échoue provoque la
      journalisation d'une grande quantité d'informations. Les deux
      premières lignes possèdent toujours le format suivant :
    

      
    
        %% [date] requête
    
        %% état HTTP nom du script CGI
      
    

      
    Si le script CGI n'a pas pu démarrer, le fichier journal
      contiendra les deux lignes supplémentaires suivantes :
    

      
    
        %%erreur
    
        message d'erreur
      
    

      
    Par contre, si l'erreur provient du renvoi par le script
      d'informations incorrectes dans les en-têtes (dû souvent à une
      bogue du script), les informations suivantes sont journalisées
      :
    

      
    
        %requête
    
        Tous les en-têtes de requête HTTP reçus
    
        Les entités POST ou PUT (s'il en existe)
    
        %réponse
    
        Tous les en-têtes générés par le script CGI
    
        %stdout
    
        la sortie standard CGI
    
        %stderr
    
        la sortie d'erreurs standard CGI
    
      
    

      
    (Les parties %stdout et %stderr seront absentes si le script
      n'a rien envoyé sur la sortie standard ou la sortie
      d'erreurs).

    Directive ScriptLog
    

    

    Description:Chemin du fichier journal des erreurs du script
CGI
    

    Syntaxe:ScriptLog chemin fichier
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_cgi, mod_cgid
    

    
    
    La directive ScriptLog permet de définir
    le chemin du fichier journal des erreurs du script CGI. Si cette
    directive n'est pas définie, aucune journalisation des erreurs n'est
    effectuée. Si elle est définie, toute erreur CGI sera enregistrée
    dans le fichier dont le nom est fourni en argument. S'il s'agit d'un
    chemin de fichier relatif, il est considéré par rapport au
    répertoire défini par la directive ServerRoot.
    
    

    
    Exemple
    ScriptLog logs/cgi_log
    

    

    
    Ce journal sera ouvert par l'utilisateur sous lequel les
    processus enfants s'exécutent, c'est à dire l'utilisateur spécifié
    par la directive du serveur User. Ceci implique que le
    répertoire dans lequel se trouve le journal doit être accessible en
    écriture pour cet utilisateur, ou bien que le fichier est créé
    manuellement et accessible en écriture pour cet utilisateur. Si vous
    placez le journal du script dans votre répertoire principal des
    journaux, ne modifiez JAMAIS les permissions de ce
    dernier afin de le le rendre accessible en écriture par
    l'utilisateur sous lequel les processus enfants s'exécutent.
    

    
    Notez que l'on ne doit activer la journalisation des scripts
    qu'à des fins de débogage lors de l'écriture de scripts CGI, et non
    de manière permanente sur un serveur en production. Elle n'est pas
    optimisée en terme de performances et d'efficacité, et peut
    présenter des problèmes de sécurité si on l'utilise dans un cadre
    autre que celui pour lequel elle a été conçue.

    Directive ScriptLogBuffer
    

    

    Description:Taille maximale des requêtes PUT ou POST qui seront
enregistrées dans le journal du script
    

    Syntaxe:ScriptLogBuffer octets
    

    Défaut:ScriptLogBuffer 1024
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_cgi, mod_cgid
    

    
    
    Cette directive permet de limiter la taille du corps de toute
    entité PUT ou POST qui sera enregistrée dans le journal, afin
    de prévenir une croissance trop importante et trop rapide du fichier
    journal due à la réception de corps de requête de grandes tailles.
    Cette directive permet de modifier cette taille maximale, dont la
    valeur par défaut est de 1024 octets.
    


    

    top
    

    Directive ScriptLogLength
    

    

    Description:Taille maximale du fichier journal des scripts
CGI
    

    Syntaxe:ScriptLogLength octets
    

    Défaut:ScriptLogLength 10385760
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_cgi, mod_cgid
    

    
    
    La directive ScriptLogLength permet de
    définir la taille maximale du fichier journal des scripts CGI. Comme
    le fichier journal accumule une grande quantité d'informations par
    erreur CGI (tous les en-têtes de la requête, toutes les sorties du
    script), il peut vite atteindre une grande taille. En limitant la
    taille du fichier, cette directive permet d'éviter les problèmes que
    causerait sa croissance sans limites. Lorsque le fichier a atteint
    cette taille maximale, plus aucune information n'y est
    enregistrée.

    Açıklama:Sunucuya yapılan isteklerin günlük kayıtlarının tutulması

    

    Durum:Temel
    

    Modül Betimleyici:log_config_module
    

    Kaynak Dosyası:mod_log_config.c
    

    Özet
    

    
    Bu modül istemci isteklerinin esnek şekilde günlüklenmesi ile
      ilgilidir. Günlükler kişiselleştirilebilir biçemdedir ve doğrudan bir
      dosyaya yazılabileceği gibi boru üzerinden harici bir sürece de
      yazılabilir. İsteğin özelliklerine bağlı olarak bazı isteklerin
      günlüklere kaydedilmesi veya kaydedilmemesi mümkün kılınmıştır.
    

    
    Bu modül üç yönerge içermektedir: Bir günlük dosyası oluşturmak için
      TransferLog, günlük
      biçemini kişiselleştirmek için LogFormat ve tek başına bir günlük
      dosyasını hem tanımlayıp hem de biçemleyen CustomLog yönergesi. Her isteğin
      çok sayıda dosyaya günlüklenmesini sağlamak için yapılandırma dosyasında
      her sunucu için birden fazla  TransferLog ve
      CustomLog yönergesi belirtilebilir.
    

    


    top
    

    

    Günlük Girdilerinin Kişiselleştirilmesi
    

    
    LogFormat ve CustomLog yönergelerinin biçem
      argümanı bir dizgedir. Bu dizge her isteği günlük dosyasına günlüklemek
      için kullanılır. Doğrudan günlük dosyalarına kopyalanmak üzere dizgesel
      sabitler içerebileceği gibi satırsonu ve sekme karakterleri olarak C
      tarzı "\n" ve "\t" denetim karakterlerini de içerebilir. Dizgesel sabit
      olarak kullanılan tırnak ve tersbölü imlerinin tersbölü ile öncelenmesi
      gerekir.
    

    
    İstek özellikleri biçem dizgesine “%” imli belirteçler
      yerleştirilerek günlüklenir. Bu belirteçler ve anlamları:
    

    
    Belirteç
        Açıklama
    

    %%
        Yüzde imi.
    

    %a
        Uzak IP adresi ve isteğin portu
          (mod_remoteip modülüne bakın).

          biçeminde hiç bayt gönderilmemişse günlüğe '-' yerine
          '0' çıktılanır.
    

    %{DEĞİŞKEN}C
        İstek içinde sunucuya gönderilen DEĞİŞKEN çerezinin

        Mikrosaniye cinsinden isteği sunmak için harcanan zaman.
    

    %{DEĞİŞKEN}e
        DEĞİŞKEN ortam değişkeninin içeriği.
    

    %f
        Dosya ismi.
    

    %h
        Uzak konak ismi. HostnameLookups yönergesine öntanımlı olan

          kaç konak için konak ismi de günlüğe kaydoluyorsa muhtemelen onların
          isimlerini içeren erişim denetim yönergelerine sahipsinizdir. Bak: Require host.
    

    %{c}h
        %h gibi, ancak her zaman, temel TCP bağlantısının 
        konak adı kaydedilir, ancak mod_remoteip gibi modüller 
        tarafından uzak konak adında yapılan değişiklikler kaydedilmez.
    

    %H
        İstek Protokolü.
    

    %{DEĞİŞKEN}i
        İstekle birlikte sunucuya gönderilen
          DEĞİŞKEN: başlık satır(lar)ının
          içeriği. Diğer modüllerde (örn. mod_headers)
          yapılan değişikliklerden etkilenir. Modüllerin çoğu bunu
          değiştirdiğinde önceki istek başlık isminin ne olduğuyla
          ilgileniyorsanız, başlığı bir ortam değişkenine kaydetmek için
          mod_setenvif modülünü kullanın ve yukarıda
          açıklandığı gibi bu değeri %{DEĞİŞKEN}e ile
          günlüğe kaydedin.
    

    %k
        Bu bağlantıda işlenen isteklerin sayısı; yani örneğin,

    	  '2', ikinci bağlantıyı, ..., vb. gösterir;
          KeepAlive kullanılmışsa
          değer anlamlıdır; aksi takdirde değer daima 0’dır.
    

    %l
        Uzak kullanıcı kimliği (sağlanmışsa, identd üzerinden).
          mod_ident modülü mevcut ve IdentityCheck yönergesine değer
          olarak On atanmış olmadıkça bu belirteç için günlüğe
          tire imi yazılır.
    

    %L
        Hata günlüğündeki istek günlük kimliği (veya bu istek için hata
          günlüğüne hiçbir şey kaydedilmemise '-'). Bu hataya neyin sebep
          olduğunu öğrenmek için ilgili hata günlüğü satırına bakın.

        Yanıttaki DEĞİŞKEN: başlık satır(lar)ının
          içeriği.
    

    %p
        Sunucunun isteği sunduğu meşru port.
    

    %{biçem}p
        Sunucunun veya istemcinin gerçek portu veya sunucunun isteği
          sunduğu meşru port. Geçerli biçemler: canonical,
          local ve remote (anlamları sırasıyla:
          meşru, yerel ve uzak).
    

    %P
        İsteği sunan çocuk sürecin süreç kimliği.
    

    %{biçem}P
        İsteği sunan çocuk sürecin süreç kimliği (pid) veya
          evre kimliği (tid). Geçerli biçemler: pid,
          tid, hextid. hextid için APR
          1.2.0 veya üstü gerekir.
    

    %q
        Sorgu dizgesi (bir sorgu dizgesi mevcutsa önüne bir ?
          eklenir yoksa hiçbir şey eklenmez).
    

    %r
        İsteğin ilk satırı.
    

    %s
        Durum. Dahili olarak yönlendirilmiş istekler için isteğin
          özgün  durumudur. İsteğin son durumu için
          %>s kullanınız.
    

    %t
        [18/Sep/2011:19:18:28 -0400] biçeminde isteğin
          alındığı tarih ve saat. Sondaki sayı zaman diliminin GMT'ye
          uzaklığıdır.
    

    %{biçem}t
        İsteğin alındığı tarih ve saat; biçem
          uzatılmış strftime(3) biçeminde belirtilmelidir (genelde
          yerelleştirme amaçlı). begin: (öntanımlı) ile başlayan
          biçemlerde süre isteğin başlangıcına göredir. end: ile
          başlayan biçemlerde ise süre isteğin işlenmesinin bi,tmesine yakın,
          günlük girdisinin yazılmaya başladığı ana göredir.
          strftime(3) tarafından desteklenen biçemlere ek olarak
          aşağıdaki biçem dizgecikleri de desteklenmektedir:
          
    
          
    secMutlak zaman başlangıcından (epoch)
            beri geçen saniye sayısı

    usec_fracmikrosaniyelik kesir
    
          
    
          Bu dizgecikler, aynı biçem dizgesi içinde bir diğeriyle birlikte veya
          strftime(3) biçemlemesiyle birlikte yer alamazlar fakat
          çok sayıda  %{biçem}t kullanılabilir.
        
    

    %T
        Saniye cinsinden, isteği sunmak için harcanan zaman.
    

    %{BİRİM}T
        BİRİM ile belirtilen zaman birimi cinsinden, isteği
          sunmak için harcanan zaman. Geçerli birimler: milisaniye için
          ms, mikrosaniye için us, saniye için
          s. s kullanımı birimsiz %T ile
          aynı sonucu verir; us kullanımı %D ile aynı
          sonucu verir. Birimli %T kullanımı 2.4.13 ve sonrasında
          geçerlidir.
    

    %u
        Uzak kullanıcı (kimlik doğrulaması istenmişse vardır; durum kodu
          (%s) 401 ise yanlış olabilir).
    

    %U
        Herhangi bir sorgu dizgesi içermeksizin istenen URL yolu.
    

    %v
        İsteği sunan sunucunun meşru sunucu ismi (ServerName).
    

    %V
        UseCanonicalName ayarı ile
          ilgili sunucu ismi.
    

    %X
        Yanıt tamamlandığında bağlantı durumu:

        
    
        
        
    X =
            Yanıt tamamlanmadan bağlantı koptu.
    
        
    + =
            Yanıt gönderildikten sonra bağlantı canlı kalabilir.
    
        
    - = 
            Yanıt gönderildikten sonra bağlantı kapatılacak.
    
        
    

    %I
        İstek ve başlıklar dahil alınan bayt sayısı. Sıfır olamaz. Bunu
          kullanmak için mod_logio etkin olmalıdır.
    

    %O
        Başlıklar dahil gönderilen bayt sayısı. Bir yanıtın
          gönderilmesinden önce istekten vazgeçilmesi gibi nadir durumlarda
          sıfır olabilir. Bunu kullanmak için mod_logio etkin
          olmalıdır.
    

    %S
        Aktarılan bayt sayısı (alınan ve gönderilen), istekler ve başlıklar
          dahil; sıfır olamaz. %I ve %O'nun birleşimidir. Bunu kullanmak için
          mod_logio etkinleştirilmelidir.
    

    %{ALANADI}^ti
        Sunucuya gönderilen istekteki ALANADI:
          Trailer satır(lar)ının içeriği.
    

    %{VARNAME}^to
        Sunucudan gönderilen yanıttaki ALANADI:
          Trailer satır(lar)ının içeriği.
    

    

    
    Değiştiriciler
    

      
    Belli öğelerin sadece belli durum kodlarıyla ilgili yanıtlarla
        basılabilmesi için bu durum kodları % iminden hemen sonra virgüllerle
        ayrılmış olarak yazılabilir. Olumsuzlama belirtmek için durum kodu listesinin önüne bir "!" konabilir.
    

      
    Biçem Dizgesi
      Anlamı
    

    %400,501{User-agent}i
      Sadece 400 ve 501 hatalarında User-agent günlüğe
        kaydedilir. Diğer durum kodları için günlüğe "-" yazılır.
      
    

    %!200,304,302{Referer}i
      200,304,302 durum kodlarından biriyle dönmeyen tüm istekler için
        Referer başlığı durum koduyla birlikte günlüğe
        kaydedilir. Aksi takdirde günlüğe "-" yazılır.
      
    

    

      
    İsteğin dahili olarak yönlendirilmesinde özgün durumunun mu yoksa son
        durumunun mu hesaba katılacağı "<" ve ">" değiştiricileri ile
        belirtilebilir. Öntanımlı olarak %s, %U, %T, %D, ve
        %r belirteçleri isteğin özgün durumuna bakarken diğerleri
        son durumuna bakarlar. Bu bakımdan örneğin, %>s
        belirteci, özgün istekteki kimliği doğrulanmış kullanıcının, dahili
        olarak kimlik doğrulaması gerekmeyen bir özkaynağa yönlendirilmesi
        halinde isteğin son durumunu kaydetmekte kullanılabilir.
    

    

    
    Bazı Bilgiler
    

      
    Güvenlik nedeniyle, 2.0.46 sürümünden itibaren %r,
        %i ve %o belirteçlerinde basılamayan
        karakterler ve diğer özel karakterler \xhh
        dizilimleri biçeminde öncelenmektedir. Burada hh yerine
        karakter numarasının onaltılık gösterimi yazılır. Bir tersbölü ile
        öncelenmesi gereken " ve \ ile
        \n, \t gibi C tarzı gösterimler bu kuralın
        dışındadır. 2.0.46 sürümünün öncesinde bu dizgeler öncelenmezdi ve ham
        günlük dosyalarıyla çalışırken dikkatli olmak gerekirdi.
    

      
    2.0 sürümünden beri 1.3 sürümünün aksine %b ve
        %B biçem belirteçleri, istemciye gönderilen bayt sayısını
        değil, HTTP yanıtının bayt sayısını ifade ederdi (bu yanıt, örneğin,
        SSL kullanıldığında veya bağlantı koptuğunda farklı uzunlukta olur).
        Artık, ağa gönderilen gerçek bayt sayısını günlüğe kaydetmek için
        mod_logio modülü tarafından sağlanan %O
        biçem belirteci kullanılmaktadır.
    

      
    
      
    Ek bilgi: mod_cache standat bir eylemci olarak değil
        hızlı bir eylemci olarak gerçeklenmiştir. Bu nedenle, içerik
        arabelleklemesi sözkonusu olduğunda %R biçem dizgesi
        herhangi bir eylemci bilgisi döndürmeyecektir.
    
      
    

    

    
    Örnekler
    

      
    Genelde herkesçe kullanılan günlük kaydı biçemleme dizgelerinden
        bazıları:
    

      
    
        
    Ortak Günlük Biçemi (OGB)
    
        
    "%h %l %u %t \"%r\" %>s %b"
    

        
    Sanal Konaklı Ortak Günlük Biçemi
    
        
    "%v %h %l %u %t \"%r\" %>s %b"
    

        
    NCSA uzun/birleşik günlük biçemi
    
        
    "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
        \"%{User-agent}i\""
    

        
    Referer başlığını içeren günlük biçemi
    
        
    "%{Referer}i -> %U"
    

        
    User-agent başlığını içeren günlük biçemi
    
        
    "%{User-agent}i"
    
      
    

      
    msec_frac gibi ek biçem dizgeciklerini kullanan bir zaman
        biçemi belirtmek isterseniz %{format}t biçem dizgesini
        defalarca kullanabilirsiniz:
    
      
    
        
    Milisaniyeleri de içeren bir zaman damgası
    
        
    "%{%d/%b/%Y %T}t.%{msec_frac}t %{%z}t"

    BufferedLogs yönergesi,
      mod_log_config modülünün çeşitli günlük girdilerini her
      isteğin hemen ardından tek tek değil, bir bütün halinde diske yazılmak
      üzere bellekte saklanmasını sağlar. Bu, bazı sistemlerde daha verimli
      disk erişimi, dolayısıyla daha yüksek başarım sağlayabilir. Sadece
      sunucu geneli için belirtilebilir, sanal konaklar için ayrı ayrı
      yapılandırılamaz.
    

    
    Bir çökme günlük verisi kaybına sebep olacağından bu yönerge
      dikkatli kullanılmalıdır.

    CustomLog Yönergesi
    

    

    Açıklama:Günlük dosyasın ismini ve girdi biçemini belirler.
    

    Sözdizimi:CustomLog  dosya|borulu-süreç
biçem|takma-ad
[env=[!]ortam-değişkeni]|
expr=ifade]
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Temel
    

    Modül:mod_log_config
    

    
    
    CustomLog yönergesi istekleri günlüğe kaydetmek
      için kullanılır. Yönerge ile bir günlük biçemi belirtilebilir ve günlük
      kaydı isteğin özelliklerine bağlı olarak ortam değişkenleri vasıtasıyla
      şarta bağlı kılınabilir.
    

    
    İlk argümanda günlüğün yazılacağı yer belirtilir. İki tür yer
      belirtilebilir:
    

    
    
      
    dosya
    
      
    ServerRoot yönergesinin
        değerine göreli bir dosya ismi.
    

      
    borulu-süreç
    
      
    "|" boru karakteri ile öncelenmiş olarak günlük
        bilgisini standart girdisinden kabul edecek sürecin ismi (veya komut
        satırı) Daha fazla bilgi için borulu
        günlüklere bakınız.

      
    Güvenlik:
    
      
    Bir borulu süreç kullanılmışsa, süreç httpd’yi
        başlatan kullanıcı tarafından başlatılacaktır. Sunucu root tarafından
        başlatılıyorsa bu root olacaktır; bu bakımdan günlük kaydını alacak
        programın güvenilir olması önemlidir.
    
      
    
      
    Bilginize
    
        
    Dosya yolunu belirtirken tersbölü çizgisi kullanılan Unix dışı
          platformlarda bile yapılandırma dosyasında bu amaçla normal bölü
          çizgilerini kullanmaya özen gösterilmelidir.
    
      
    
    
    

    
    İkinci argümanda günlüğe ne yazılacağı belirtilir. Ya evvelce
      LogFormat yönergesi ile
      tanımlanmış bir takma-ad ya da içeriği Günlük Girdilerinin Kişiselleştirilmesi bölümünde
      açıklanmış bir biçem dizgesi olabilir.
    

    
    Örneğin, aşağıdaki iki yönerge kümesi aynı etkiye sahiptir:
    

    
    # Biçem dizgesi yerine takma ad içeren CustomLog
LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog "logs/access_log" common

# Biçem dizgesinin kendisini içeren CustomLog
CustomLog "logs/access_log" "%h %l %u %t \"%r\" %>s %b"
    


    
    Üçüncü argüman isteğe bağlı olup,belli bir isteğin günlüğe kaydedilip
      kaydedilmeyeceğini belirler. Koşul, sunucu ortamında belli bir değişkenin varlığı veya
      yokluğu olabilir (bir 'env=!isim' durumu).
      İstenirse koşul keyfi bir mantıksal ifade
      olarak da belirtilebilir. Eğer koşul sağlanmazsa istek günlüğe
      kaydedilmez. İfadede bulunan HTTP başlıklarına başvurular bu başlık
      isimlerinin Vary başlığına eklenmesine sebep olmaz.
    

    
    Ortam değişkenleri mod_setenvif
      ve/veya mod_rewrite modülleri kullanılarak her istek
      için ayrı ayrı atanabilir. Örneğin, GIF biçemli resimler için yapılan
      istekleri ana günlük dosyasına değil de başka bir dosyaya kaydetmek
      isterseniz:
    

    
    SetEnvIf Request_URI \.gif$ gif-image
CustomLog "gif-requests.log" common env=gif-image
CustomLog "nongif-requests.log" common env=!gif-image
    


    
    Veya eski RefererIgnore yönergesinin davranışını taklit
      etmek isterseniz:
    

    
    SetEnvIf Referer example\.com localreferer
CustomLog "referer.log" referer env=!localreferer

    GlobalLog yönergesi ana sunucu yapılandırması ve
       tüm tanımlı sanal konaklarca paylaşılan bir günlük tanımlar.
    

    
    GlobalLog yönergesi aşağıdaki farklar dışında
       CustomLog yönergesine eşdeğerdir:
    
    
      
       
    • GlobalLog sanal konak bağlamında belirtilirse
         geçersizdir.
      • 
       
    • Sanal konaklar küresel bağlamda belirtilmiş bir
         CustomLog yönergesinin tersine
         GlobalLog yönergesini kendi
         CustomLog yönergesiymiş gibi kullanır.

    LogFormat Yönergesi

    Modül:mod_log_config
    

    
    
    Bu yönerge erişim günlüğü dosyasının girdi biçemini belirler.
    

    
    LogFormat yönergesi iki şekilde kullanılabilir.
      Tek argüman belirtilebilen ilkinde daha sonra
      TransferLog yönergelerinde belirtilen günlüklerde
      kullanılmak üzere günlük biçemini belirler. Bu günlük biçemi yukarıda
      açıklanan biçem belirteçlerinden
      oluşur. Bu tek argüman yerine aşağıda açıklandığı gibi önceki bir
      LogFormat yönergesinde tanımlanmış bir günlük
      biçemine atıf yapan bir takma-ad da belirtilebilir.
    

    
    LogFormat yönergesinin ikinci kullanım şeklinde
      biçem bir takma-ad için tanımlanır. Bu takma ad
      daha sonraki LogFormat veya CustomLog yönergelerinde aynı biçem
      dizgesini uzun uzadıya yazmamak için takma-ad olarak
      kullanılır. Bir LogFormat yönergesi bir takma ad
      tanımlamaktan başka bir şey yapmaz; yani, yaptığı iş
      sadece bir takma ad tanımlamaktan ibarettir, biçemi uygulamaz veya
      biçemi öntanımlı hale getirmez. Bu bakımdan sonraki TransferLog yönergelerini de
      etkilemeyecektir. Ayrıca, LogFormat yönergesi bir
      takma ada başka bir takma ad tanımlamakta da kullanılamaz. Bir takma
      adın yüzde imi (%) içeremeyeceğine de dikkat ediniz.
    

    
    LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost_common

    Bir günlük biçemi tanımlanmasını ve şarta bağlı günlük kaydını mümkün
      kılmaması haricinde CustomLog yönergesi gibidir. Günlük biçemi yerine kendinden
      önce yer alan bir LogFormat yönergesinde tanımlanan
      bir takma ad kullanılır. Açıkça bir günlük biçemi takma adı
      belirtilmedikçe Ortak Günlük Biçemi öntanımlıdır.
    

    
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""

    Directive AcceptFilter
    

    

    Description:Permet d'optimiser la configuration d'une socket pour
l'écoute d'un protocole
    

    Syntaxe:AcceptFilter protocole filtre
d'acceptation
    

    Contexte:configuration globale
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Cette directive permet d'effectuer une optimisation de la socket
    d'écoute d'un type de protocole en fonction du système
    d'exploitation. Le but premier est de faire en sorte que le noyau
    n'envoie pas de socket au processus du serveur jusqu'à ce que
    des données soient reçues, ou qu'une requête HTTP complète soit mise
    en tampon. Seuls les Filtres d'acceptation de FreeBSD, le filtre plus
    primitif TCP_DEFER_ACCEPT sous Linux, et la version
    optimisée d'AcceptEx() de Windows sont actuellement supportés.
    

    
    L'utilisation de l'argument none va désactiver tout
    filtre d'acceptation pour ce protocole. Ceci s'avère utile pour les
    protocoles qui nécessitent l'envoi de données par le serveur en
    premier, comme ftp: ou nntp:
    
    
    AcceptFilter nntp none
    


    
    Les noms de protocoles par défaut sont https pour le
    port 443 et http pour tous les autres ports. Pour
    spécifier un autre protocole à utiliser avec un port en écoute,
    ajoutez l'argument protocol à la directive Listen.
    

    
    Sous FreeBSD, les valeurs par défaut sont :
    
    
    AcceptFilter http httpready
AcceptFilter https dataready
    


    
    Le filtre d'acceptation httpready met en tampon des
    requêtes HTTP entières au niveau du noyau. Quand une requête
    entière a été reçue, le noyau l'envoie au serveur. Voir la page de
    manuel de accf_http(9) pour plus de détails. Comme les requêtes
    HTTPS sont chiffrées, celles-ci n'autorisent que le filtre accf_data(9).
    

    
    Sous Linux, les valeurs par défaut sont :
    
    
    AcceptFilter http data
AcceptFilter https data
    


    
    Le filtre TCP_DEFER_ACCEPT de Linux ne supporte pas
    la mise en tampon des requêtes http. Toute valeur autre que
    none active le filtre TCP_DEFER_ACCEPT
    pour ce protocole. Pour plus de détails, voir la page de
    manuel Linux de tcp(7).
    

    
    Sous Windows, les valeurs par défaut sont :
    
    
    AcceptFilter http connect
AcceptFilter https connect
    


    
    Le module MPM pour Windows mpm_winnt utilise la directive
    AcceptFilter comme commutateur de l'API AcceptEx(), et ne supporte
    pas la mise en tampon du protocole http. connect
    utilise l'API AcceptEx(), extrait aussi les adresses réseau finales,
    mais à l'instar de none, la valeur connect
    n'attend pas la transmission des données initiales.
    

    
    Sous Windows, none utilise accept() au lieu
    d'AcceptEx(), et ne recycle pas les sockets entre les connexions.
    Ceci s'avère utile pour les interfaces réseau dont le pilote est
    défectueux, ainsi que pour certains fournisseurs de réseau comme les
    pilotes vpn, ou les filtres anti-spam, anti-virus ou
    anti-spyware.
    

    
    
      
    L'AcceptFilter data (Windows)
    

      
    Jusqu'à la version 2.4.23, le filtre d'acceptation data
      attendait que des données aient été transmises et que le tampon de données
      initial et l'adresse réseau finale aient été déterminés par l'invocation
      AcceptEx(). Cette implémentation étant vulnérable à une attaque de type
      denial of service, elle a été désactivée.
    

      
    La version actuelle de httpd prend par défaut le filtre
      connect sous Windows, et reprendra la valeur
      data si data est spécifié. Il est fortement
      conseillé aux utilisateurs des versions plus anciennes de définir
      explicitement le filtre connect pour leurs AcceptFilter
      comme indiqué plus haut.

    Directive AcceptPathInfo
    

    

    Description:Les ressources acceptent des informations sous forme d'un
nom de chemin en fin de requête.
    

    Syntaxe:AcceptPathInfo On|Off|Default
    

    Défaut:AcceptPathInfo Default
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Noyau httpd
    

    Module:core
    

    

    
    Cette directive permet de définir si les requêtes contenant des
    informations sous forme d'un nom de chemin suivant le nom d'un
    fichier réel (ou un fichier qui n'existe pas dans un répertoire qui
    existe) doivent être acceptées ou rejetées. Les scripts peuvent
    accéder à cette information via la variable d'environnement
    PATH_INFO.
    

    
    Supposons par exemple que /test/ pointe vers un
    répertoire qui ne contient que le fichier here.html.
    Les requêtes pour /test/here.html/more et
    /test/nothere.html/more vont affecter la valeur
    /more à la variable d'environnement
    PATH_INFO.
    

    
    L'argument de la directive AcceptPathInfo
    possède trois valeurs possibles :
    
    
    
    
    Off
    Une requête ne sera acceptée que si
    elle correspond à un chemin qui existe. Par conséquent, une requête
    contenant une information de chemin après le nom de fichier réel
    comme /test/here.html/more dans l'exemple ci-dessus
    renverra une erreur "404 NOT FOUND".
    

    
    On
    Une requête sera acceptée si la partie
    principale du chemin correspond à un fichier existant. Dans
    l'exemple ci-dessus /test/here.html/more, la requête
    sera acceptée si /test/here.html correspond à un nom de
    fichier valide.
    

    
    Default
    Le traitement des requêtes est
    déterminé par le gestionnaire responsable de la requête.
    Le gestionnaire de base pour les fichiers normaux rejette par défaut
    les requêtes avec PATH_INFO. Les gestionnaires qui
    servent des scripts, commecgi-script et isapi-handler, acceptent en général par
    défaut les requêtes avec PATH_INFO.
    
    
    

    
    Le but premier de la directive AcceptPathInfo est de
    vous permettre de remplacer le choix du gestionnaire d'accepter ou
    de rejeter PATH_INFO. Ce remplacement est nécessaire
    par exemple, lorsque vous utilisez un filtre, comme INCLUDES, pour générer un contenu basé
    sur PATH_INFO. Le gestionnaire de base va en général
    rejeter la requête, et vous pouvez utiliser la configuration
    suivante pour utiliser un tel script :
    

    <Files "mypaths.shtml">
  Options +Includes
  SetOutputFilter INCLUDES
  AcceptPathInfo On
</Files>

    Directive AccessFileName
    

    

    Description:Nom du fichier de configuration distribué
    

    Syntaxe:AccessFileName nom-du-fichier
[nom-du-fichier] ...
    

    Défaut:AccessFileName .htaccess
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Au cours du traitement d'une requête, le serveur recherche le
    premier fichier de configuration existant à partir de la liste
    de noms dans chaque répertoire composant le chemin du document, à
    partir du moment où les fichiers de configuration distribués sont activés pour ce répertoire. Par exemple
    :
    

    
    AccessFileName .acl
    


    
    avant de renvoyer le document
    /usr/local/web/index.html, le serveur va rechercher les
    fichiers /.acl, /usr/.acl,
    /usr/local/.acl et /usr/local/web/.acl
    pour y lire d'éventuelles directives, à moins quelles n'aient été
    désactivées avec
    

    
    <Directory "/">
    AllowOverride None
</Directory>

    Directive AddDefaultCharset
    

    

    Description:Paramètre jeu de caractères par défaut à ajouter quand le
type de contenu d'une réponse est text/plain ou
text/html
    

    Syntaxe:AddDefaultCharset On|Off|jeu de caractères
    

    Défaut:AddDefaultCharset Off
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Cette directive spécifie une valeur par défaut pour le paramètre
    jeu de caractères du type de média (le nom d'un codage de
    caractères) à ajouter à une réponse, si et seulement si le type de
    contenu de la réponse est soit text/plain, soit
    text/html. Ceci va remplacer
    tout jeu de caractères spécifié dans le corps de la réponse via un
    élément META, bien que cet effet dépende en fait
    souvent de la configuration du client de l'utilisateur. La
    définition de AddDefaultCharset Off désactive cette
    fonctionnalité. AddDefaultCharset On ajoute un jeu de
    caractères par défaut de iso-8859-1. Toute autre valeur
    peut être définie via le paramètre jeu de caractères, qui
    doit appartenir à la liste des valeurs de
    jeux de caractères enregistrés par l'IANA à utiliser dans les
    types de média Internet (types MIME).
    Par exemple :
    

    
    AddDefaultCharset utf-8
    


    
    La directive AddDefaultCharset ne doit
    être utilisée que lorsque toutes les ressources textes auxquelles
    elle s'applique possèdent le jeu de caractère spécifié, et qu'il est
    trop contraignant de définir leur jeu de caractères
    individuellement. Un exemple de ce type est l'ajout du paramètre jeu
    de caractères aux ressources comportant un contenu généré, comme les
    scripts CGI hérités qui peuvent être vulnérables à des attaques de
    type cross-site scripting à cause des données utilisateurs incluses

    Directive AllowEncodedSlashes
    

    

    Description:Détermine si les séparateurs de chemin encodés sont
autorisés à transiter dans les URLs tels quels
    

    Syntaxe:AllowEncodedSlashes On|Off|NoDecode
    

    Défaut:AllowEncodedSlashes Off
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:L'option NoDecode est disponible depuis la version
2.3.12.
    

    
    
    La directive AllowEncodedSlashes permet
    l'utilisation des URLs contenant des séparateurs de chemin
    encodés dans la partie chemin
    (%2F pour / et même %5C pour
    \ sur les systèmes concernés).
    

    
    Avec la valeur par défaut, Off, de telles URLs sont
    refusées et provoquent le renvoi d'une erreur 404 (Not found).
    

    
    Avec la valeur On, ces URLs sont acceptées, et les
    slashes encodés sont décodés comme tout autre caractère codé.
    

    
    Avec la valeur NoDecode, ces URLs sont acceptées,
    mais les slashes codés ne sont pas décodés et laissés dans leur état
    codé.
    

    
    Définir AllowEncodedSlashes à
    On est surtout utile en association avec
    PATH_INFO.
    

    
    Note
    
      
    Si le codage des slashes dans la partie chemin est nécessaire,
      l'utilisation de l'option NoDecode est fortement
      recommandée par mesure de sécurité. Permettre le décodage des
      slashes pourrait éventuellement induire l'autorisation de chemins
      non sûrs.

    Directive AllowOverride
    

    

    Description:Types de directives autorisées dans les fichiers
.htaccess
    

    Syntaxe:AllowOverride All|None|type directive
[type directive] ...
    

    Défaut:AllowOverride None à partir de la version 2.3.9, AllowOverride
All pour les versions antérieures
    

    Contexte:répertoire
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Lorsque le serveur trouve un fichier .htaccess (dont
    le nom est défini par la directive AccessFileName), il doit savoir lesquelles
    des directives placées dans ce fichier sont autorisées à modifier la
    configuration préexistante.
    

    
    Valable seulement dans les sections
    <Directory>
    
    La directive AllowOverride ne peut être
    utilisée que dans les sections <Directory> définies sans expressions
    rationnelles, et non dans les sections <Location>, <DirectoryMatch> ou
    <Files>.
    
    

    
    Lorsque cette directive et la directive AllowOverrideList sont définies à None, les
    fichiers .htaccess sont totalement
    ignorés. Dans ce cas, le serveur n'essaiera même pas de lire les
    fichiers .htaccess du système de fichiers.
    

    
    Lorsque cette directive est définie à All, toute
    directive valable dans le Contexte .htaccess sera
    autorisée dans les fichiers .htaccess.
    

    
    L'argument type directive peut contenir les
    groupements de directives suivants (voir ce
    document pour obtenir la liste à jour des directives activées pour
    chaque type de directive) :
    

    
    
      
    AuthConfig
    

      
    

      Permet l'utilisation des directives d'autorisation (AuthDBMGroupFile,
      AuthDBMUserFile,
      AuthGroupFile,
      AuthName,
      AuthType, AuthUserFile, Require, etc...).
    

      
    FileInfo
    

      
    
      Permet l'utilisation des directives qui contrôlent les types de
      documents (directives  ErrorDocument, ForceType, LanguagePriority,
      SetHandler, SetInputFilter, SetOutputFilter, et directives du
      module mod_mime Add* et Remove*), des metadonnées
      des documents (Header, RequestHeader, SetEnvIf, SetEnvIfNoCase, BrowserMatch, CookieExpires, CookieDomain, CookieStyle, CookieTracking, CookieName), des directives du
      module mod_rewrite directives (RewriteEngine, RewriteOptions, RewriteBase, RewriteCond, RewriteRule), des directives du
      module mod_alias directives (Redirect, RedirectTemp, RedirectPermanent, RedirectMatch), et de la directive
      Action du module
      mod_actions.
      
    

      
    Indexes
    

      
    
      Permet l'utilisation des directives qui contrôlent l'indexation
      des répertoires (AddDescription,
      AddIcon, AddIconByEncoding,
      AddIconByType,
      DefaultIcon, DirectoryIndex, FancyIndexing,
      HeaderName, IndexIgnore, IndexOptions, ReadmeName,
      etc...).
    

      
    Limit
    

      
    
      Permet l'utilisation des directives contrôlant l'accès au serveur
      (Allow, Deny et Order).
    

      
    Nonfatal=[Override|Unknown|All]
    

      
    
      Permet d'utiliser l'option AllowOverride pour rendre les erreurs
      de syntaxe non fatales dans les fichiers .htaccess : au lieu de
      causer une Internal Server Error, les directives non autorisées ou
      non reconnues seront ignorées et un avertissement enregistré dans
      le journal :
      
      
          
    • Nonfatal=Override rend les directives
	  interdite par AllowOverride non fatales.
      • 
          
    • Nonfatal=Unknown rend les directives
	  inconnues non fatales. Sont concernées les erreurs de frappe
	  et les directives implémentées par un module non chargé.
      • 
          
    • Nonfatal=All rend toutes les directives
	  précédentes non fatales.
      • 
      
    
      
    Notez qu'une erreur de syntaxe dans une directive valide
      causera toujours une internal server error.
    
      
    Sécurité
    
          Les erreurs non fatales peuvent être à l'origine de problèmes
	  de sécurité pour les utilisateurs de fichiers .htaccess. Par
	  exemple, si AllowOverride interdit AuthConfig, toute
	  configuration utilisateur destinée à restreindre l'accès à un
	  site ne sera pas prise en compte.
      
    
      
    

      
    Options[=Option,...]
    

      
    
      Permet l'utilisation des directives contrôlant les fonctionnalités
      spécifiques d'un répertoire (Options et XBitHack). "Options" doit être
      suivi d'un signe "égal", puis d'une liste d'options séparées par des
      virgules (pas d'espaces) ; ces options doivent être définies à
      l'aide de la commande Options.

      
    Désactivation implicite des options
    
      
    Bien que la liste des options disponibles dans les fichiers
      .htaccess puisse être limitée par cette directive, tant qu'un
      directive Options est
      autorisée, toute autre option héritée peut être désactivée en
      utilisant la syntaxe non-relative. En d'autres termes, ce
      mécanisme ne peut pas forcer une option spécifique à rester
      activée tout en permettant à toute autre option d'être
      activée.
      
    

      
    
      AllowOverride Options=Indexes,MultiViews
      
    
      
      
    
    
    

    
    Exemple :
    

    
    AllowOverride AuthConfig Indexes
    


    
    Dans l'exemple ci-dessus, toutes les directives qui ne font
    partie ni du groupe AuthConfig, ni du groupe
    Indexes, provoquent une erreur "internal
    server error".
    

    
    Pour des raisons de sécurité et de performance, ne
    définissez pas AllowOverride à autre chose que
    None dans votre bloc <Directory "/">.
    Recherchez plutôt (ou créez) le bloc <Directory>
    qui se réfère au répertoire où vous allez précisément placer un
    fichier .htaccess.

    Lorsque le serveur trouve un fichier .htaccess
    (comme spécifié par la directive AccessFileName), il doit savoir lesquelles
    des directives déclarées dans ce fichier peuvent remplacer des
    directives des fichiers de configuration du serveur.
    

    
    Seulement disponible dans les sections <Directory>
    
    La directive AllowOverrideList n'est
    disponible que dans les sections <Directory> spécifiées sans expressions
    rationnelles.
    
    

    
    Lorsque cette directive et la directive AllowOverride sont définies à
    None, les fichiers .htaccess sont totalement ignorés. Dans
    ce cas, le serveur ne cherchera même pas à lire des fichiers
    .htaccess dans le système de fichiers.
    

    
    Example:
    

    
    AllowOverride None
AllowOverrideList Redirect RedirectMatch
    


    
    Dans l'exemple ci-dessus, seules les directives
    Redirect et RedirectMatch sont autorisées.
    Toutes les autres provoqueront une erreur interne du serveur.
    

    
    Example:
    

    
    AllowOverride AuthConfig
AllowOverrideList CookieTracking CookieName
    


    
    Dans l'exemple ci-dessus, la directive AllowOverride autorise les directives du
    groupement AuthConfig, et
    AllowOverrideList n'autorise que deux
    directives du groupement FileInfo. Toutes les autres
    provoqueront une erreur interne du serveur.

    Compatibilité:Disponible à partir de la version 2.4.13 du serveur HTTP
Apache
    

    
    
    La directive CGIPassAuth permet aux
    scripts d'accéder aux en-têtes d'autorisation HTTP tels que
    Authorization, en-tête nécessaire aux scripts qui
    implémente une authentification HTTP de base. Normalement, ces
    en-têtes HTTP sont invisibles pour les scripts car ils leurs
    permettraient de voir les identifiants et mots de passe
    utilisés pour accéder au serveur lorsque l'authentification HTTP de
    base est activée au niveau du serveur web. Cette directive doit être
    définie à "On" lorsque des scripts sont autorisés à implémenter une
    authentification HTTP de base.
    

    
    Cette directive constitue une alternative à l'option de
    compilation SECURITY_HOLE_PASS_AUTHORIZATION qui était
    déjà disponible dans les versions précédentes du serveur HTTP
    Apache.
    

    
    Cette option est prise en compte par tout module qui utilise
    ap_add_common_vars(), comme mod_cgi,
    mod_cgid, mod_proxy_fcgi,
    mod_proxy_scgi, etc... En particulier, elle affecte
    les modules qui ne traitent pas à proprement parler les requêtes,
    mais utilisent quand-même cette API, comme
    mod_include ou mod_ext_filter. Les
    modules tiers qui n'utilisent pas ap_add_common_vars()
    peuvent aussi choisir de prendre en compte cette option.

    Surcharges autorisées:Options
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Cette directive active la génération d'un en-tête
    Content-MD5 selon les définitions des RFC 1864 et
    2616.
    

    
    MD5 est un algorithme permettant de générer un condensé (parfois
    appelé "empreinte") à partir de données d'une taille aléatoire ; le
    degré de précision est tel que la moindre altération des données
    d'origine entraîne une altération de l'empreinte.
    

    
    L'en-tête Content-MD5 permet de vérifier
    l'intégrité de la réponse HTTP dans son ensemble. Un serveur mandataire
    ou un client peut utiliser cet en-tête pour rechercher une
    éventuelle modification accidentelle de la réponse au cours de sa
    transmission. Exemple d'en-tête :
    

    
    
      Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
    
    

    
    Notez que des problèmes de performances peuvent affecter votre
    serveur, car l'empreinte est générée pour chaque requête (il n'y a
    pas de mise en cache).
    

    
    L'en-tête Content-MD5 n'est envoyé qu'avec les
    documents servis par le module core, à l'exclusion
    de tout autre module. Ainsi, les documents SSI, les sorties de
    scripts CGI, et les réponses à des requêtes partielles (byte range)
    ne comportent pas cet en-tête.

    La directive DefaultRuntimeDir permet de
    définir le répertoire dans lequel le serveur va créer les différents
    fichiers relatifs à son exécution (mémoire partagée, verrous,
    etc...). Si le chemin spécifié est relatif, le chemin absolu sera

    Note: si la valeur de ServerRoot n'a pas
   été spécifiée avant d'utiliser cette directive, c'est la valeur par

    Cette directive a été désactivée. Pour la compatibilité
    ascendante avec les anciens fichiers de configuration, elle peut
    être spécifiée avec la valeur none, c'est à dire sans
    type de médium par défaut. Par exemple :
    

    
    DefaultType None
    


    
    DefaultType None n'est disponible que dans les

    l'assignement d'un type de médium via les extensions de fichiers, ou
    la directive ForceType pour
    attribuer un type de médium à des ressources spécifiques. Dans le

    De plus, le second paramètre permet d'affecter une valeur à la
    variable définie par le premier. Cette variable peut être référencée
    dans le fichier de configuration via la syntaxe ${VAR}.
    La portée de la variable est toujours globale, et n'est jamais

    Directive <Directory>

sous-répertoires, et à leur contenu.
    

    Syntaxe:<Directory chemin répertoire>
... </Directory>
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Les balises <Directory> et
    </Directory> permettent de regrouper un ensemble
    de directives qui ne s'appliquent qu'au répertoire précisé,
    à ses sous-répertoires, et aux fichiers situés dans ces
    sous-répertoires. Toute directive
    autorisée dans un contexte de répertoire peut être utilisée.
    chemin répertoire est soit le chemin absolu d'un
    répertoire, soit une chaîne de caractères avec caractères génériques
    utilisant la comparaison Unix de style shell. Dans une chaîne de
    caractères avec caractères génériques, ? correspond à
    un caractère quelconque, et * à toute chaîne de
    caractères. Les intervalles de caractères [] sont aussi
    autorisés. Aucun caractère générique ne peut remplacer le caractère
    `/', si bien que l'expression <Directory
    "/*/public_html"> ne conviendra pas pour le chemin
     * /home/user/public_html, alors que <Directory
    "/home/*/public_html"> conviendra. Exemple :
    

    
    <Directory "/usr/local/httpd/htdocs">
  Options Indexes FollowSymLinks
</Directory>
    


    
    Les chemins de répertoires contenant des espaces doivent être
    entourés de guillemets afin d'empêcher l'interprétation de ces
    espaces comme fins d'arguments.
    

    
    
      
    Soyez prudent avec l'argument chemin répertoire : il
      doit correspondre exactement au chemin du système de fichier
      qu'Apache httpd utilise pour accéder aux fichiers. Les directives
      comprises dans une section <Directory> ne
      s'appliqueront pas aux fichiers du même répertoire auxquels on
      aura accédé via un chemin différent, per exemple via un lien
      symbolique.
    
    
    

    
     Les Expressions rationnelles
    peuvent aussi être utilisées en ajoutant le caractère
    ~. Par exemple :
    

    
    <Directory ~ "^/www/[0-9]{3}">

</Directory>
    


    
    pourra correspondre à tout répertoire situé dans /www/ et dont le
    nom se compose de trois chiffres.
    

    
    Si plusieurs sections <Directory> (sans expression rationnelle)
    correspondent au répertoire (ou à un de ses parents) qui contient le
    document, les directives de la section <Directory> dont le chemin est le plus
    court sont appliquées en premier, en s'intercalant avec les
    directives des fichiers .htaccess. Par
    exemple, avec
    

    
    <Directory "/">
  AllowOverride None
</Directory>

<Directory "/home">
  AllowOverride FileInfo
</Directory>
    


    
    l'accès au document /home/web/dir/doc.html emprunte
    le chemin suivant :
    

    
      
      
    • Aplication de la directive AllowOverride None
      (qui désactive les fichiers .htaccess).
      • 

      
    • Application de la directive AllowOverride
      FileInfo (pour le répertoire /home).
      • 

      
    • Application de toute directive FileInfo qui se
      trouverait dans d'éventuels fichiers /home/.htaccess,
      /home/web/.htaccess ou
      /home/web/dir/.htaccess, dans cet ordre.
      • 
    
    

    
    Les directives associées aux répertoires sous forme d'expressions
    rationnelles ne sont prises en compte qu'une fois toutes les
    directives des sections sans expressions rationnelles appliquées.
    Alors, tous les répertoires avec expressions rationnelles sont
    testés selon l'ordre dans lequel ils apparaissent dans le fichier de
    configuration. Par exemple, avec
    

    
    <Directory ~ "abc$">
  # ... directives ici ...
</Directory>
    


    
    la section avec expression rationnelle ne sera prise en compte
    qu'après les sections <Directory> sans expression rationnelle
    et les fichiers .htaccess. Alors, l'expression
    rationnelle conviendra pour /home/abc/public_html/abc
    et la section <Directory>
    correspondante s'appliquera.
    

   
    Notez que la politique d'accès par défaut
   dans les sections <Directory "/"> consiste à
   autoriser tout accès sans restriction. Ceci signifie qu'Apache httpd va servir tout fichier
   correspondant à une URL. Il est recommandé de modifier cette
   situation à l'aide d'un bloc du style
    

    
    <Directory "/">
  Require all denied
</Directory>
    


    
    puis d'affiner la configuration pour les répertoires que vous
    voulez rendre accessibles. Voir la page Conseils à propos de sécurité
    pour plus de détails.
    

    
    Les sections <Directory> se situent
    dans le fichier httpd.conf. Les directives <Directory> ne peuvent pas être imbriquées
    et ne sont pas autorisées dans les sections <Limit> ou <LimitExcept>.

    Les balises <DirectoryMatch>
    et </DirectoryMatch> permettent de regrouper un
    ensemble de directives qui ne s'appliqueront qu'au répertoire
    précisé (et aux fichiers qu'il contient), comme pour la section <Directory>. Cependant, le
    répertoire est précisé sous la forme d'une expression rationnelle. Par exemple :
    

    
    <DirectoryMatch "^/www/(.+/)?[0-9]{3}/">
    # ...
</DirectoryMatch>
    


    
    convient pour les sous-répertoires de /www/ dont
    le nom se compose de trois chiffres.
    

    
    Compatibilité
    
      Avant la version 2.3.9, cette directive s'appliquait aussi aux
      sous-répertoires (comme la directive <Directory>), et ne tenait pas compte du
      symbole de fin de ligne ($). Depuis la version 2.3.9, seuls les
      répertoires qui correspondent à l'expression sont affectés par les
      directives contenues dans la section.
    
    

    
    slash de fin
    
      Cette directive s'applique aux requêtes pour des répertoires avec
      ou sans slash de fin ; les expressions contenant un symbole de fin
      de ligne ($) doivent donc faire l'objet d'une attention
      particulière.
    
    
    
    
    A partir de la version 2.4.8, les groupes nommés et les
    références arrières sont extraits et enregistrés dans
    l'environnement avec leur nom en majuscules et préfixé
    par "MATCH_". Ceci permet
    de référencer des URLs dans des expressions
    ou au sein de modules comme mod_rewrite. Pour
    éviter toute confusion, les références arrières numérotées (non
    nommées) sont ignorées. Vous devez utiliser à la place des groupes
    nommés.
    


    <DirectoryMatch "^/var/www/combined/(?<sitename>[^/]+)">
    Require ldap-group cn=%{env:MATCH_SITENAME},ou=combined,o=Example

    Cette directive permet de définir le répertoire à partir duquel
    httpd va servir les fichiers. S'il ne correspond
    pas à un Alias, le chemin
    de l'URL sera ajouté par le serveur à la racine des documents afin
    de construire le chemin du document recherché. Exemple :
    

    
    DocumentRoot "/usr/web"
    


    
    un accès à http://my.example.com/index.html se
    réfère alors à /usr/web/index.html. Si chemin
    répertoire n'est pas un chemin absolu, il est considéré comme
    relatif au chemin défini par la directive ServerRoot.
    

    
    Le répertoire défini par la directive
    DocumentRoot ne doit pas comporter de slash
    final.

    Module:core
    

    
    
    Cette directive définit si httpd peut utiliser
    la projection en mémoire (Memory-Mapping) quand il doit lire le contenu
    d'un fichier pendant qu'il est servi. Par défaut, lorsque le
    traitement d'une requête requiert l'accès aux données contenues dans
    un fichier -- par exemple, pour servir un fichier interprété par le
    serveur à l'aide de mod_include -- Apache httpd projette
    le fichier en mémoire si le système d'exploitation le permet.
    

    
    Cette projection en mémoire induit parfois une amélioration des
    performances. Sur certains systèmes cependant, il est préférable de
    désactiver la projection en mémoire afin d'éviter certains problèmes
    opérationnels :
    

    
      
    
    • Sur certains systèmes multi-processeurs, la projection en
    mémoire peut dégrader les performances du programme
    httpd.
      • 
    
    • S'il fait l'objet d'une projection en mémoire par
    httpd, la suppression ou la troncature d'un
    fichier peut provoquer un crash de httpd avec une
    erreur de segmentation.
      • 
    
    

    
    Pour les configurations de serveur sujettes à ce genre de
    problème, il est préférable de désactiver la projection en mémoire
    des fichiers servis en spécifiant :
    
    
    
    EnableMMAP Off
    


    
    Pour les montages NFS, cette fonctionnalité peut être
    explicitement désactivée pour les fichiers concernés en spécifiant

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Par défaut à Off depuis la version 2.3.9.
    

    
    
    Cette directive définit si le programme httpd
    peut utiliser le support sendfile du noyau pour transmettre le
    contenu des fichiers aux clients. Par défaut, lorsque le traitement
    d'une requête ne requiert pas l'accès aux données contenues dans un
    fichier -- par exemple, pour la transmission d'un fichier statique
    -- Apache httpd utilise sendfile pour transmettre le contenu du fichier
    sans même lire ce dernier, si le système d'exploitation le
    permet.
    

    
    Ce mécanisme sendfile évite la séparation des opérations de
    lecture et d'envoi, ainsi que les réservations de tampons. sur
    certains systèmes cependant, ou sous certains systèmes de fichiers,
    il est préférable de désactiver cette fonctionnalité afin d'éviter
    certains problèmes opérationnels :
    

    
      
    
    • Certains systèmes peuvent présenter un support sendfile
    défectueux que le système de compilation n'a pas détecté, en
    particulier si les exécutables ont été compilés sur une autre
    machine, puis copiés sur la première avec un support sendfile
    défectueux.
      • 
    
    • Sous Linux, l'utilisation de sendfile induit des bogues lors de
    la récupération des paquets de vérification TCP (TCP-checksum) avec
    certaines cartes réseau lorsqu'on utilise IPv6.
      • 
    
    • Sous Linux sur Itanium, sendfile peut s'avérer incapable de
    traiter les fichiers de plus de 2 Go.
      • 
    
    • Avec un montage réseau de DocumentRoot (par exemple NFS, SMB, CIFS,
    FUSE), le
    noyau peut s'avérer incapable de servir un fichier de ce montage
    réseau en passant par son propre cache.
      • 
    
    

    
    Pour les configurations de serveur non sujettes à ce genre de
    problème, vous pouvez activer cette fonctionnalité en
    spécifiant :
    

    
    EnableSendfile On
    


    
    Pour les montages réseau, cette fonctionnalité peut être
    explicitement désactivée pour les fichiers concernés en spécifiant
    :
    

    
    <Directory "/path-to-nfs-files">
  EnableSendfile Off
</Directory>
    

    
    Veuillez noter que la configuration de la directive
    EnableSendfile dans un contexte de répertoire
    ou de fichier .htaccess n'est pas supportée par
    mod_cache_disk. Le module ne prend en compte la
    définition de EnableSendfile que dans un
    contexte global.

    Syntaxe:ErrorDocument code erreur document

    Surcharges autorisées:FileInfo
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Apache httpd peut traiter les problèmes et les erreurs de quatre
    manières,
    

    
      
      
    1. afficher un simple message d'erreur au contenu fixe
      2. 

      
    2. afficher un message personnalisé
      3. 

      
    3. rediriger en interne vers un chemin d'URL local pour traiter
      le problème ou l'erreur
      4. 

      
    4. rediriger vers une URL externe pour traiter
      le problème ou l'erreur
      5. 
    
    

    
    La première option constitue le comportement par défaut; pour
    choisir une des trois autres options, il faut configurer Apache à
    l'aide de la directive ErrorDocument, suivie
    du code de la réponse HTTP et d'une URL ou d'un message. Apache
    httpd fournit parfois des informations supplémentaires à propos du
    problème ou de l'erreur.
    

    
    A partir de la version 2.4.13, il est possible d'utiliser la syntaxe des expressions dans cette directive
    afin de générer des chaînes et URLs dynamiques.
    

    
    Les URLs peuvent commencer par un slash (/) pour les chemins web
    locaux (relatifs au répertoire défini par la directive DocumentRoot), ou se présenter sous la
    forme d'une URL complète que le client pourra résoudre.
    Alternativement, un message à afficher par le navigateur pourra être
    fourni. Notez que la décision de considérer le paramètre comme URL,
    chemin ou message intervient avant toute interprètation
    d'expression. Exemples :
    

    
    ErrorDocument 500 http://example.com/cgi-bin/server-error.cgi
ErrorDocument 404 /errors/bad_urls.php
ErrorDocument 401 /subscription_info.html
ErrorDocument 403 "Sorry can't allow you access today"
ErrorDocument 403 Forbidden!
ErrorDocument 403 /errors/forbidden.py?referrer=%{escape:%{HTTP_REFERER}}
    


    
    De plus, on peut spécifier la valeur spéciale default
    pour indiquer l'utilisation d'un simple message d'Apache httpd codé en
    dur. Bien que non nécessaire dans des circonstances normales, la
    spécification de la valeur default va permettre de
    rétablir l'utilisation du simple message d'Apache httpd codé en dur pour
    les configurations qui sans cela, hériteraient d'une directive
    ErrorDocument existante.
    

    
    ErrorDocument 404 /cgi-bin/bad_urls.pl

<Directory "/web/docs">
  ErrorDocument 404 default
</Directory>
    


    
    Notez que lorsque vous spécifiez une directive
    ErrorDocument pointant vers une URL distante
    (c'est à dire tout ce qui commence par le préfixe http), le serveur
    HTTP Apache va
    envoyer une redirection au client afin de lui indiquer où trouver le
    document, même dans le cas où ce document se trouve sur le serveur
    local. Ceci a de nombreuses conséquences dont la plus importante
    réside dans le fait que le client ne recevra pas le code d'erreur
    original, mais au contraire un code de statut de redirection. Ceci
    peut en retour semer la confusion chez les robots web et divers
    clients qui tentent de déterminer la validité d'une URL en examinant
    le code de statut. De plus, si vous utilisez une URL distante avec
    ErrorDocument 401, le client ne saura pas qu'il doit
    demander un mot de passe à l'utilisateur car il ne recevra pas le
    code de statut 401. C'est pourquoi, si vous utilisez une
    directive ErrorDocument 401, elle devra faire référence
    à un document par le biais d'un chemin local.
    

    
    Microsoft Internet Explorer (MSIE) ignore par défaut les messages
    d'erreur générés par le serveur lorsqu'ils sont trop courts et
    remplacent ses propres messages d'erreur "amicaux". Le seuil de
    taille varie en fonction du type d'erreur, mais en général, si la
    taille de votre message d'erreur est supérieure à 512 octets, il y a
    peu de chances pour que MSIE l'occulte, et il sera affiché par ce
    dernier. Vous trouverez d'avantage d'informations dans l'article de
    la base de connaissances Microsoft Q294807.
    

    
    Bien que la plupart des messages d'erreur internes originaux
    puissent être remplacés, ceux-ci sont cependant conservés dans
    certaines circonstances sans tenir compte de la définition de la
    directive ErrorDocument. En
    particulier, en cas de détection d'une requête mal formée, le
    processus de traitement normal des requêtes est immédiatement
    interrompu, et un message d'erreur interne est renvoyé, ceci afin de
    se prémunir contre les problèmes de sécurité liés aux requêtes mal
    formées.
    

    
    Si vous utilisez mod_proxy, il est en général préférable
    d'activer ProxyErrorOverride afin d'être en
    mesure de produire des messages d'erreur personnalisés pour le
    compte de votre serveur d'origine. Si vous n'activez pas
    ProxyErrorOverride, Apache httpd ne générera pas de messages d'erreur
    personnalisés pour le contenu mandaté.

    La directive ErrorLog permet de définir le
    nom du fichier dans lequel le serveur va journaliser toutes les
    erreurs qu'il rencontre. Si le file-path n'est pas
    absolu, il est considéré comme relatif au chemin défini par la
    directive ServerRoot.
    

    
    ErrorLog "/var/log/httpd/error_log"
    


    
    Si le file-path commence par une barre verticale
    "(|)", il est considéré comme une commande à lancer pour traiter la
    journalisation de l'erreur.
    

    
    ErrorLog "|/usr/local/bin/httpd_errors"
    


    
    Voir les notes à propos des journaux
    redirigés pour plus d'informations.
    

    
    L'utilisation de syslog à la place d'un nom de
    fichier active la journalisation via syslogd(8) si le système le
    supporte. Le dispositif syslog par défaut est local7,
    mais vous pouvez le modifier à l'aide de la syntaxe
    syslog:facility, où facility peut
    être remplacé par un des noms habituellement documentés dans la page
    de man syslog(1). Le dispositif syslog local7 est
    global, et si il est modifié dans un serveur virtuel, le dispositif
    final spécifié affecte l'ensemble du serveur. La même règle s'applique au
    tag syslog qui utilise par défaut le nom du binaire du serveur HTTP Apache
    httpd dans la plupart des cas. Vous pouvez aussi modifier cette
    valeur en utilisant la syntaxe syslog::tag.
    

    
    ErrorLog syslog:user
ErrorLog syslog:user:httpd.srv1
ErrorLog syslog::httpd.srv2
    


    
    SECURITE : Voir le document conseils à propos de
    sécurité pour des détails sur les raisons pour lesquelles votre

    Note
    
      
    Lors de la spécification d'un chemin de fichier sur les
      plates-formes non-Unix, on doit veiller à n'utiliser que des
      slashes (/), même si la plate-forme autorise l'utilisation des
      anti-slashes (\). Et d'une manière générale, il est recommandé de
      n'utiliser que des slashes (/) dans les fichiers de
      configuration.

    Directive ErrorLogFormat
    

    

    Description:Spécification du format des entrées du journal des erreurs
    

    Syntaxe: ErrorLogFormat [connection|request] format
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La directive ErrorLogFormat permet de
    spécifier quelles informations supplémentaires vont être enregistrées
    dans le journal des erreurs en plus du message habituel.
    

    
    # Exemple simple
ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M"
    


    
    La spécification de connection ou
    request comme premier paramètre permet de définir des
    formats supplémentaires, ce qui a pour effet de journaliser des
    informations additionnelles lorsque le premier message est
    enregistré respectivement pour une connexion ou une requête
    spécifique. Ces informations additionnelles ne sont enregistrées
    qu'une seule fois par connexion/requête. Si le traitement d'une
    connexion ou d'une requête ne génère aucun message dans le journal,
    alors aucune information additionnelle n'est enregistrée.
    

    
    Il peut arriver que certains items de la chaîne de format ne
    produisent aucune sortie. Par exemple, l'en-tête Referer n'est
    présent que si le message du journal est associé à une requête et s'il
    est généré à un moment où l'en-tête Referer a déjà été lu par le
    client. Si aucune sortie n'est générée, le comportement par défaut
    consiste à supprimer tout ce qui se trouve entre l'espace précédent
    et le suivant. Ceci implique que la ligne de journalisation est
    divisée en champs ne contenant pas d'espace séparés par des espaces.
    Si un item de la chaîne de format ne génère aucune sortie,
    l'ensemble du champ est omis. Par exemple, si l'adresse distante
    %a du format [%t] [%l] [%a] %M  n'est
    pas disponible, les crochets qui l'entourent ne seront eux-mêmes pas
    enregistrés. Il est possible d'échapper les espaces par un anti-slash
    afin qu'ils ne soient pas considérés comme séparateurs de champs.
    La combinaison '% ' (pourcentage espace) est un délimiteur de
    champ de taille nulle qui ne génère aucune sortie.
    

    
    Ce comportement peut être changé en ajoutant des modificateurs à
    l'item de la chaîne de format. Le modificateur -
    (moins) provoque l'enregistrement d'un signe moins si l'item
    considéré ne génère aucune sortie. Pour les formats à enregistrement
    unique par connexion/requête, il est aussi possible d'utiliser le
    modificateur + (plus). Si un item ne générant aucune
    sortie possède le modificateur plus, la ligne dans son ensemble est
    omise.
    

    
    Un modificateur de type entier permet d'assigner un niveau de
    sévérité à un item de format. L'item considéré ne
    sera journalisé que si la sévérité du message n'est pas
    plus haute que le niveau de sévérité spécifié. Les
    valeurs possibles vont de 1 (alert) à 15 (trace8), en passant par 4
    (warn) ou 7 (debug).
    

    
    Par exemple, voici ce qui arriverait si vous ajoutiez des
    modificateurs à l'item %{Referer}i qui enregistre le
    contenu de l'en-tête Referer.
    

    
    Item modifiéSignification
    

    
    %-{Referer}i
    Enregistre le caractère - si l'en-tête
    Referer n'est pas défini.
    
    

    
    %+{Referer}i
    N'enregistre rien si l'en-tête
    Referer n'est pas défini.
    
    

    
    %4{Referer}i
    N'enregistre le contenu de l'en-tête Referer que si
    la sévérité du message de journalisation est supérieure à 4.
    
    

    

    
    Certains items de format acceptent des paramètres supplémentaires
    entre accolades.

    L'item de format identifiant journal %L génère un
    identifiant unique pour une connexion ou une requête. Il peut servir
    à déterminer quelles lignes correspondent à la même connexion ou
    requête ou quelle requête est associée à tel connexion. Un item de
    format %L est aussi disponible dans le module
    mod_log_config, mais il permet dans ce contexte de
    corréler les entrées du journal des accès avec celles du journal des
    erreurs. Si le module mod_unique_id est chargé,
    c'est son identifiant unique qui sera utilisé comme identifiant de
    journal pour les requêtes.

	ces variables pendant l'exécution en configurant
	mod_status. Notez que d'autres modules sont
	susceptibles de s'appuyer sur ce tableau de bord.
    

    
    Cette directive s'applique au serveur dans son ensemble, et ne
    peut pas être activée/désactivée pour un serveur virtuel
    particulier. Notez que l'extraction des informations d'état étendues
    peut ralentir le serveur. Notez aussi que cette définition ne peut
    pas être modifiée au cours d'un redémarrage graceful.
    

    
    
    
    Notez que le chargement de mod_status définit
    automatiquement ExtendedStatus à On, et que d'autres modules tiers
    sont susceptibles d'en faire de même. De tels modules ont besoin
    d'informations détaillées à propos de l'état de tous les processus.
    Depuis la version 2.3.6, mod_status a définit la
    valeur par défaut à On, alors qu'elle était à Off dans les versions

    Directive FileETag

de l'en-tête de réponse HTTP ETag pour les fichiers statiques
    

    Syntaxe:FileETag composant ...
    

    Défaut:FileETag MTime Size

    Surcharges autorisées:FileInfo
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:La valeur par défaut était "INode MTime Size"
dans les versions 2.3.14 et antérieures.
    

    
    
    
    La directive FileETag définit les
    caractéristiques de fichier utilisées lors de la génération de
    l'en-tête de réponse HTTP ETag (entity tag) quand le
    document est contenu dans un fichier statique (la valeur de
    ETag
    est utilisée dans le cadre de la gestion du cache pour préserver la
    bande passante réseau). La directive
    FileETag vous permet maintenant de choisir
    quelles caractéristiques du fichier vont être utilisées, le cas
    échéant. Les mots-clés reconnus sont :
    
    

    
    
     
    INode
    
     
    Le numéro d'i-node du fichier sera inclus dans le processus de
     génération
    
     
    MTime
    
     
    La date et l'heure auxquelles le fichier a été modifié la
     dernière fois seront incluses
    
     
    Size
    
     
    La taille du fichier en octets sera incluse
    
     
    All
    
     
    Tous les champs disponibles seront utilisés. Cette définition
     est équivalente à : 
     
    FileETag INode MTime Size
    

    
     
    Digest
    
     
    Si un document est à base de fichier, le champ ETag sera
     généré à partir du condensé du fichier.
    
     
    None
    
     
    Si le document se compose d'un fichier, aucun champ
     ETag ne sera inclus dans la réponse
    
    
    

    
    Les mots-clés INode, MTime, 
    Size et Digest peuvent être préfixés par + ou
    -, ce qui permet de modifier les valeurs par défaut
    héritées d'un niveau de configuration plus général. Tout mot-clé
    apparaissant sans aucun préfixe annule entièrement et immédiatement
    les configurations héritées.
    

    
    Si la configuration d'un répertoire contient
    FileETag INode MTime Size, et si un de
    ses sous-répertoires contient FileETag -INode, la
    configuration de ce sous-répertoire (qui sera propagée vers tout
    sous-répertoire qui ne la supplante pas), sera équivalente à
    FileETag MTime Size.
    
    
    Inclusions côté serveur
    
    Aucun champ ETag n'est généré pour les réponses interprétées par
    mod_include, car l'entité de la réponse peut
    changer sans modification de l'INode, MTime, Size ou Digest du
    fichier statique contenant les directives SSI.

    Directive <Files>
    

    

    Description:Contient des directives qui s'appliquent aux fichiers
précisés
    

    Syntaxe:<Files nom fichier> ... </Files>
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:All
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La directive <Files> limite
    la portée des directives qu'elle contient aux fichiers précisés.
    Elle est comparable aux directives <Directory> et <Location>. Elle doit se terminer par une
    balise </Files>. Les directives contenues dans
    cette section s'appliqueront à tout objet dont le nom de base (la
    dernière partie du nom de fichier) correspond au fichier spécifié.
    Les sections <Files> sont
    traitées selon l'ordre dans lequel elles apparaissent dans le
    fichier de configuration, après les sections <Directory> et la lecture des fichiers
    .htaccess, mais avant les sections <Location>. Notez que les
    sections <Files> peuvent être
    imbriquées dans les sections <Directory> afin de restreindre la portion
    du système de fichiers à laquelle ces dernières vont
    s'appliquer.
    

    
    L'argument filename peut contenir un nom de fichier
    ou une chaîne de caractères avec caractères génériques, où
    ? remplace un caractère, et * toute chaîne
    de caractères.
    
    
    <Files "cat.html">
    # Insérer ici des directives qui s'appliquent au fichier cat.html
</Files>

<Files "?at.*">
    # Les directives insérées ici s'appliqueront aux fichiers
    # cat.html, bat.html, hat.php, et ainsi de suite.
</Files>
    

    
    
    On peut aussi utiliser les Expressions rationnelles en ajoutant la
    caractère ~. Par exemple :
    

    
    <Files ~ "\.(gif|jpe?g|png)$">
    #...
</Files>
    


    
    correspondrait à la plupart des formats graphiques de l'Internet.
    Il est cependant préférable d'utiliser la directive <FilesMatch>.
    

    
    Notez qu'à la différence des sections <Directory> et <Location>, les sections <Files> peuvent être utilisées dans les
    fichiers .htaccess. Ceci permet aux utilisateurs de
    contrôler l'accès à leurs propres ressources, fichier par
    fichier.

    La section <FilesMatch>
    limite la portée des directives qu'elle contient aux fichiers
    spécifiés, tout comme le ferait une section <Files>. Mais elle accepte aussi les
    expressions rationnelles. Par
    exemple :
    

    
    <FilesMatch ".+\.(gif|jpe?g|png)$">
    # ...
</FilesMatch>
    


    
    correspondrait à la plupart des formats graphiques de
    l'Internet.
    

    
    Les caractères .+ au début de l'expression
    rationnelle permettent de s'assurer que les fichiers de nom
    .png, ou .gif, par exemple, ne seront pas
    pris en compte.
    

    
    A partir de la version 2.4.8, les groupes nommés et les
    références arrières sont extraits et enregistrés dans
    l'environnement avec leur nom en majuscules et préfixé
    par "MATCH_". Ceci permet
    de référencer des URLs dans des expressions
    ou au sein de modules comme mod_rewrite. Pour
    éviter toute confusion, les références arrières numérotées (non
    nommées) sont ignorées. Vous devez utiliser à la place des groupes
    nommés.

    Compatibilité:Disponible à partir de la version 2.4.47 du serveur HTTP Apache
    

    
    
    Cette directive permet de définir le nombre maximal de réponses
    "pipelinées" qui restent en attente tant que des requêtes "pipelinées" sont
    reçues. Lorsque cette limite est dépassée, l'envoi des réponses sur le
    réseau est forcé en mode bloqué jusqu'à ce que leur nombre repasse en
    dessous de la limite.
    

    
    La directive FlushMaxPipelined permet de limiter
    la consommation de mémoire. Lorsqu'elle est définie à 0, le
    pipelining est désactivé, et lorsqu'elle est définie à -1, il n'y
    a plus de limite (mais la directive FlushMaxThreshold
    s'applique quand-même).

    dessous du seuil spécifié.
    

    
    La directive FlushMaxThreshold permet de limiter
    la consommation de mémoire. Lorsqu'elle est définie à 0 ou à une
    valeur trop petite, aucune donnée n'est mise en attente, mais dans le cas
    des MPMs threadés, il peut alors y avoir plus de threads occupés en attente du
    réseau, ce qui diminue d'autant le nombre de threads disponibles pour
    traiter les autres connexions simultanées.

    Lorsqu'elle est placée dans un fichier .htaccess ou
    une section <Directory>, <Location>, ou <Files>, cette directive force
    l'identification du type MIME des fichiers spécifiés à la valeur de
    l'argument type médium. Par exemple, si vous possédez un
    répertoire ne contenant que des fichiers GIF, et si vous ne voulez
    pas leur ajouter l'extension .gif, vous pouvez utiliser
    :
    

    
    ForceType image/gif
    


    
    Notez que cette directive l'emporte sur d'autres associations de
    type de médium indirectes définies dans mime.types ou via la
    directive AddType.
    

    
    Vous pouvez aussi annuler toute définition plus générale de
    ForceType en affectant la valeur
    None à l'argument type médium :
    

    
    # force le type MIME de tous les fichiers à image/gif:
<Location "/images">
  ForceType image/gif
</Location>

# mais utilise les méthodes classiques d'attribution du type MIME
# dans le sous-répertoire suivant :
<Location "/images/mixed">
  ForceType None
</Location>
    

    
    
    A la base, cette directive écrase le type de contenu généré pour
    les fichiers statiques servis à partir du sytème de fichiers. Pour
    les ressources autres que les fichiers statiques pour lesquels le
    générateur de réponse spécifie en général un type de contenu, cette
    directive est ignorée.
    

    
    Note
    
    
    Lorsque des directives explicites comme SetHandler ou
    module="mod_mime">AddHandler ne s'appliquent
    pas à la requête courante, le nom du gestionnaire interne
    normalement défini par ces directives correspondra alors au type de
    contenu spécifié par cette directive. Il s'agit d'un
    comportement historique que certains modules
    tiers, comme mod_php, peuvent interpréter comme un type de contenu
    artificiel ne servant qu'à indiquer le module qui doit prendre en
    compte la requête considérée. Dans la mesure du
    possible, il est conseillé d'éviter les
    configurations qui comportent de tels types artificiels en utilisant
    les directives SetHandler ou
    AddHandler.

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Cette directive active la recherche DNS afin de pouvoir
    journaliser les nom d'hôtes (et les passer aux programmes CGI et aux
    inclusions SSI via la variable REMOTE_HOST). La valeur
    Double déclenche une double recherche DNS inverse. En
    d'autres termes, une fois la recherche inverse effectuée, on lance
    une recherche directe sur le résultat de cette dernière. Au moins
    une des adresses IP fournies par la recherche directe doit
    correspondre à l'adresse originale (ce que l'on nomme
    PARANOID dans la terminologie "tcpwrappers").
    

    
    Quelle que soit la configuration, lorsqu'on utilise
    mod_authz_host pour contrôler l'accès en fonction
    du nom d'hôte, une double recherche DNS inverse est effectuée,
    sécurité oblige. Notez cependant que le résultat de cette double
    recherche n'est en général pas accessible, à moins que vous n'ayez
    spécifié HostnameLookups Double. Par exemple, si vous
    n'avez spécifié que HostnameLookups On, et si une
    requête concerne un objet protégé par des restrictions en fonction
    du nom d'hôte, quel que soit le résultat de la double recherche
    inverse, les programmes CGI ne recevront que le résultat de la
    recherche inverse simple dans la variable
    REMOTE_HOST.
    

    
    La valeur par défaut est Off afin de préserver le
    traffic réseau des sites pour lesquels la recherche inverse n'est
    pas vraiment nécessaire. Cette valeur par défaut est aussi bénéfique
    pour les utilisateurs finaux car il n'ont ainsi pas à subir de temps
    d'attente supplémentaires dus aux recherches DNS. Les sites
    fortement chargés devraient laisser cette directive à
    Off, car les recherches DNS peuvent prendre des temps
    très longs. Vous pouvez éventuellement utiliser hors ligne
    l'utilitaire logresolve, compilé par défaut dans
    le sous-répertoire bin de votre répertoire
    d'installation, afin de déterminer les noms d'hôtes associés aux
    adresses IP journalisées.
    

    
    Enfin, si vous avez des directives Require à base de
    nom, une recherche de nom d'hôte sera effectuée quelle que soit
    la définition de la directive HostnameLookups.

    Syntaxe:HttpProtocolOptions [Strict|Unsafe] [RegisteredMethods|LenientMethods]
 [Allow0.9|Require1.0]
    

    Défaut:HttpProtocolOptions Strict LenientMethods Allow0.9
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Disponible à partir des versions 2.2.32 et 2.4.24 du serveur HTTP
Apache
    

    
    
    Cette directive permet de modifier les règles qui s'appliquent à la ligne
    de requête HTTP (RFC 7230
    §3.1.1) et aux champs des en-têtes des requêtes HTTP (RFC 7230
    §3.2), qui s'appliquent maintenant par défaut ou en utilisant
    l'option Strict. L'option Unsafe
    a été ajoutée pour pouvoir restaurer les anciens
    comportements nécessaires aux anciens modules et applications et aux agents
    utilisateurs personnalisés considérés comme obsolètes.
    

    
    Ces règles
    s'appliquant avant le traitement de la requête, elles doivent, pour être prises en
    compte, être définies
    au niveau global ou dans la première section par défaut du serveur virtuel
    qui correspond à la requête considérée, par interface IP/port et non par
    nom.
    

    
    Cette directive accepte trois paramètres issus de la liste suivante, ceux
    qui ne sont pas spécifiés prenant leur valeur par défaut :
    

    
    
    
    Strict|Unsafe
    
    
    
    
    Avant l'introduction de cette directive, les interpréteurs de requêtes du
    serveur HTTP Apache toléraient un grand nombre de formats en entrée qui
    n'étaient pas forcément conformes au protocole. RFC 7230 §9.4
    Request Splitting et §9.5 Response
    Smuggling ne rappellent que deux des risques potentiels induits par des
    requêtes non conformes, alors que RFC 7230
    §3.5 signale les risques encourus par l'acceptation de blancs non
    conformes dans les lignes de requête. Avec l'introduction de cette
    directive, toutes les règles de grammaire de la spécification doivent être
    respectées dans le mode d'opérations par défaut Strict.
    

    
    Risques de sécurité liés au mode Unsafe
    
    
    Il est fortement déconseillé aux utilisateurs d'utiliser le mode
    d'opération Unsafe, ou
    UnsafeWhitespace, en particulier pour les déploiements de
    serveurs ouverts sur l'extérieur et/ou accessibles au public. Si un moniteur
    défectueux ou autre logiciel spécialisé ne s'exécutant que sur un intranet
    nécessite une interface, les utilisateurs ne doivent utiliser les options de
    type UnSafe qu'en cas de nécessité et uniquement au sein d'un serveur
    virtuel bien spécifique et sur un réseau privé.
    
    
    

    
    Exemple de requête provoquant l'envoi d'un message HTTP 400 en
	mode Strict
    
        
        # Missing CRLF
    
        GET / HTTP/1.0\n\n
      
    
      
    Utilitaires en ligne de commande et CRLF
    
        
    Il peut s'avérer nécessaire de forcer certains utilitaires à utiliser
	CRLF ; si ce n'est pas le cas, httpd reverra une réponse HTTP 400 comme
	dans le cas précédent. Par exemple, le client OpenSSL s_client
	doit utiliser le paramètre -crlf pour fonctionner correctement.
    
        
    Pour détecter des problèmes tels que l'absence de CRLF, vous pouvez
	utiliser la directive DumpIOInput qui permet de décortiquer
	les requêtes HTTP.
    
      
    
    
    
    
    RegisteredMethods|LenientMethods
    
    
    
    
    La section de la RFC 7231
    §4.1 "Request Methods" "Overview" indique que les serveurs doivent
    renvoyer un message d'erreur lorsque la ligne de requête comporte une
    méthode non supportée. C'est déjà le cas lorsque l'option
    LenientMethods est utilisée, mais les administrateurs ont la
    possibilité de limiter les méthodes utilisées via l'option
    RegisteredMethods en enregistrant toute méthode non standard
    via la directive RegisterHttpMethod, en particulier
    si l'option Unsafe est utilisée.
    

    
    Compatibilité avec le mandat direct
    
    
    L'option
    RegisteredMethods ne doit pas être utilisée
    pour les serveurs mandataires car ces derniers ne connaissent pas les
    méthodes supportées par les serveurs originaux.
    
    
    

    
    Exemple de requête provoquant l'envoi d'un message HTTP 501 en
	mode LenientMethods
    
        
        # Méthode HTTP inconnue
    
        WOW / HTTP/1.0\r\n\r\n

    
        # Méthode HTTP spécifiée en minuscules
    
        get / HTTP/1.0\r\n\r\n
    
      
    
      
    
      
    Allow0.9|Require1.0
    
      
    
    
    La section de la RFC 2616
    §19.6 "Compatibility With Previous Versions" encouragait les
    serveurs HTTP à supporter les anciennes requêtes HTTP/0.9. La RFC 7230 va
    cependant à son encontre via sa préconisation "Le souhait de supporter les
    requêtes HTTP/0.9 a été supprimé" et y adjoint des commentaires dans RFC 7230 Appendix
    A. A ce titre, l'option Require1.0 permet à l'utilisateur
    d'inhiber le comportement induit par l'option par défaut
    Allow0.9.
    

    
    Exemple de requête provoquant l'envoi d'un message HTTP 400 en
	mode Require1.0
    
        
        # Version HTTP non supportée
    
        GET /\r\n\r\n
      
    
    
    
    
    

    
    La consultation des messages enregistrés dans le journal
    ErrorLog, configuré via la directive
    LogLevel avec un niveau info, pourra
    vous aider à identifier de telles requêtes non conformes ainsi que leur
    provenance. Les utilisateurs devront accorder une attention particulière aux
    messages d'erreur de type 400 dans le journal access pour détecter les
    requêtes apparemment valides mais rejetées.

    Directive <If>
    

    

    Description:Contient des directives qui ne s'appliquent que si une
condition est satisfaite au cours du traitement d'une
requête
    

    Syntaxe:<If expression> ... </If>
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:All
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Les conditions imbriquées sont supportées à partir de la version
2.4.26 du serveur HTTP Apache
    

    
    
    La directive <If> évalue une
    expression à la volée, et applique les directives qu'elle contient
    si et seulement si l'expression renvoie la valeur "vrai". Par
    exemple :
    

    
    <If "-z req('Host')">
    


    
    serait satisfaite pour les requêtes HTTP/1.0 sans en-tête
    Host:. Les expressions peuvent contenir différents
    opérateurs de type shell pour la comparaison de chaînes
    (==, !=, <, ...), la
    comparaison d'entiers (-eq, -ne, ...), ou
    à usages divers (-n, -z, -f,
    ...). Les expressions rationnelles sont aussi supportées,
    

    
    <If "%{QUERY_STRING} =~ /(delete|commit)=.*?elem/">
    


    
    ainsi que les comparaison de modèles de type shell et de
    nombreuses autres opérations. Ces opérations peuvent être effectuées
    sur les en-têtes de requêtes (req), les variables
    d'environnement (env), et un grand nombre d'autres
    propriétés. La documentation complète est disponible dans Les expressions dans le serveur HTTP Apache.
    

    
    Cette section de configuration ne peut contenir que des
    directives qui supportent le contexte de répertoire.
    

    
    
    Certain variables, such as CONTENT_TYPE and other
    response headers, are set after <If> conditions have already
    been evaluated, and so will not be available to use in this
    directive.

    Directive <IfDefine>
    

    

    Description:Contient des directives qui ne s'appliqueront que si un
test retourne "vrai" au démarrage du serveur
    

    Syntaxe:<IfDefine [!]paramètre> ...
    </IfDefine>
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:All
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La section <IfDefine
    test>...</IfDefine> permet de
    conférer un caractère conditionnel à un ensemble de directives. Les
    directives situées à l'intérieur d'une section <IfDefine> ne s'appliquent que si
    test est vrai. Si test est faux, tout ce qui
    se trouve entre les balises de début et de fin est ignoré.
    

    
    test peut se présenter sous deux formes :
    

    
      
      
    • nom paramètre
      • 

      
    • !nom paramètre
      • 
    
    

    
    Dans le premier cas, les directives situées entre les balises de
    début et de fin ne s'appliqueront que si le paramètre nommé nom
    paramètre est défini. Le second format inverse le test, et
    dans ce cas, les directives ne s'appliqueront que si nom
    paramètre n'est pas défini.
    

    
    L'argument nom paramètre est une définition qui peut
    être effectuée par la ligne de commande
    httpd via le paramètre
    -Dparamètre au démarrage du serveur, ou via la
    directive Define.
    

    
    Les sections <IfDefine>
    peuvent être imbriquées, ce qui permet d'implémenter un test
    multi-paramètres simple. Exemple :
    

    
    httpd -DReverseProxy -DUseCache -DMemCache ...
    
    
    <IfDefine ReverseProxy>
  LoadModule proxy_module   modules/mod_proxy.so
  LoadModule proxy_http_module   modules/mod_proxy_http.so
  <IfDefine UseCache>
    LoadModule cache_module   modules/mod_cache.so
    <IfDefine MemCache>
      LoadModule mem_cache_module   modules/mod_mem_cache.so
    </IfDefine>
    <IfDefine !MemCache>
      LoadModule cache_disk_module   modules/mod_cache_disk.so
    </IfDefine>
  </IfDefine>
</IfDefine>

    La section <IfDirective
    test>...</IfDirective> permet de regrouper des
    directives dont le traitement n'est effectué que si une directive
    particulière est présente, autrement dit si l'expression test est
    évaluée à true. Si l'expression test est évaluée à false, toutes
    les lignes qui se trouvent entre les balises de début et de fin de la
    section sont ignorées.
    

    
    L'expression test de la section <IfDirective> peut prendre les deux formes
    suivantes :
    

    
      
      
    • directive-name
      • 

      
    • !directive-name
      • 
    
    

    
    Dans le premier cas, les directives qui se situent entre les balises de
    début et de fin de la section ne sont traitées que si une directive de nom
    directive-name est disponible à cet instant. Dans le second cas, la condition est
    inversée, et les directives ne sont traitées que si
    directive-name n'est pas disponible.
    

    
    Cette section ne doit être utilisée que si vous devez partager le même
    fichier de configuration entre plusieurs versions de
    httpd, sans tenir compte de la disponibilité de telle ou
    telle directive. Dans une configuration standard, il est inutile de placer
    les directives dans des sections <IfDirective>.

    Compatibilité:Disponible à partir de la version 2.4.34 du serveur HTTP Apache
    

    
    
    La section <IfFile filename>...</IfFile>
    permet de conditionner le traitement de directives à
    l'existence d'un fichier sur disque. Ainsi, les directives définies au sein
    d'une section <IfFile> ne seront
    traitées que si le fichier filename existe. Si le fichier
    filename n'existe pas, tout ce qui se trouve entre les marqueurs
    start et end sera ignoré. filename peut être un chemin absolu ou
    relatif au chemin défini par la directive ServerRoot.
    

    
    Le paramètre filename de l'en-tête d'une section <IfFile> peut prendre la même forme que la variable
    test de la section <IfDefine> ; à ce titre, le résultat du test peut
    être inversé en plaçant le caractère ! juste avant
    filename.
    
    
   
    
    Si filename est un chemin relatif, il sera généré par rapport
    au chemin défini par la directive ServerRoot. Lorsque la directive <IfFile> intervient avant la définition de la
    directive ServerRoot,
    filename sera relatif au répertoire racine par défaut du serveur
    ou au répertoire racine passé dans la ligne de commande via l'option
    -d.

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Les identificateurs de modules sont disponibles dans les
versions 2.1 et supérieures.
    

    
    
    La section <IfModule
    test>...</IfModule> permet de conférer à
    des directives un caractère conditionnel basé sur la présence d'un
    module spécifique. Les directives situées dans une section
    <IfModule> ne s'appliquent que
    si test est vrai. Si test est faux, tout ce
    qui se trouve entre les balises de début et de fin est ignoré.
    

    
    test peut se présenter sous deux formes :
    

    
      
      
    • module
      • 

      
    • !module
      • 
    
    

    
    Dans le premier cas, les directives situées entre les balises de
    début et de fin ne s'appliquent que si le module module
    est présent -- soit compilé avec le binaire Apache httpd, soit chargé
    dynamiquement via la directive LoadModule. Le second format inverse le test, et dans
    ce cas, les directives ne s'appliquent que si module
    n'est pas présent.
    

    
    L'argument module peut contenir soit l'identificateur
    du module, soit le nom du fichier source du module. Par exemple,
    rewrite_module est un identificateur et
    mod_rewrite.c le nom du fichier source
    correspondant. Si un module comporte plusieurs fichiers sources,
    utilisez le nom du fichier qui contient la chaîne de caractères
    STANDARD20_MODULE_STUFF.
    

    
    Les sections <IfModule>
    peuvent être imbriquées, ce qui permet d'implémenter des tests
    multi-modules simples.
    

    
    Cette section ne doit être utilisée que si votre fichier de
    configuration ne fonctionne qu'en fonction de la présence ou de
    l'absence d'un module spécifique. D'une manière générale, il n'est
    pas nécessaire de placer les directives à l'intérieur de sections

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Utilisation des caractères génériques dans la partie chemin depuis la
version 2.3.6
    

    
    
    Cette directive permet l'inclusion d'autres fichiers de
    configuration dans un des fichiers de configuration du serveur.
    

    
    On peut utiliser des caractères génériques de style Shell
    (fnmatch()) aussi bien dans la partie nom de fichier du
    chemin que dans la partie répertoires pour inclure plusieurs
    fichiers en une
    seule fois, selon leur ordre alphabétique. De plus, si la directive
    Include pointe vers un répertoire, Apache
    httpd inclura tous les fichiers de ce répertoire et de tous ces
    sous-répertoires. L'inclusion de répertoires entiers est cependant
    déconseillée, car il est fréquent d'oublier des fichiers
    temporaires dans un répertoire, ce qui causerait une erreur
    httpd en cas d'inclusion. Pour inclure des
    fichiers qui correspondent à un certain modèle, comme *.conf par
    exemple, nous vous recommandons d'utiliser plutôt la syntaxe avec
    caractères génériques comme ci-dessous.
    

    
    La directive Include
    échouera avec un code d'erreur si une expression
   contenant des caractères génériques ne correspond à aucun fichier.
   Pour ignorer les expressions contenant des caractères génériques ne
   correspondant à aucun fichier, utilisez la directive IncludeOptional.
    

    
    Le chemin fichier spécifié peut être soit un chemin absolu, soit
    un chemin relatif au répertoire défini par la directive ServerRoot.
    

    
    Exemples :
    

    
    Include /usr/local/apache2/conf/ssl.conf
Include /usr/local/apache2/conf/vhosts/*.conf
    


    
    ou encore, avec des chemins relatifs au répertoire défini par la
    directive ServerRoot :
    

    
    Include conf/ssl.conf
Include conf/vhosts/*.conf
    


    
    On peut aussi insérer des caractères génériques dans la partie
    répertoires du chemin. Dans l'exemple suivant, la directive
    échouera si aucun sous-répertoire de conf/vhosts ne contient au
    moins un fichier *.conf :
    
  
    
    Include conf/vhosts/*/*.conf
    


    
    Par contre, dans l'exemple suivant, la directive sera simplement
    ignorée si aucun sous-répertoire de conf/vhosts ne contient au
    moins un fichier *.conf :
    

    
    IncludeOptional conf/vhosts/*/*.conf

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Noyau httpd

    Compatibilité:Disponible à partir de la version 2.3.6 du serveur HTTP
Apache. Après la version 2.4.30, les chemins de fichiers non existants et
ne comportant pas de caractères génériques ne génèrent plus d'erreurs de syntaxe
    

    
    
    Cette directive permet d'inclure des fichiers dans les fichiers
    de configuration du serveur. Elle fonctionne de manière identique à
    la directive Include, mais au lieu de
    générer une erreur, elle sera ignorée silensieusement si malgré
    l'utilisation de caractères génériques, le chemin de fichier ou de
    répertoire spécifié n'existe pas dans le système de fichiers.

    Directive KeepAlive
    

    

    Description:Active les connexions HTTP persistantes
    

    Syntaxe:KeepAlive On|Off
    

    Défaut:KeepAlive On
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    L'extension Keep-Alive de HTTP/1.0 et l'implémentation des
    connexions persistantes dans HTTP/1.1 ont rendu possibles des
    sessions HTTP de longue durée, ce qui permet de transmettre
    plusieurs requêtes via la même connexion TCP. Dans certains cas, le
    gain en rapidité pour des documents comportant de nombreuses images
    peut atteindre 50%. Pour activer les connexions persistantes,
    définissez KeepAlive On.
    

    
    Pour les clients HTTP/1.0, les connexions persistantes ne seront
    mises en oeuvre que si elles ont été spécialement demandées par un
    client. De plus, une connexion persistante avec un client HTTP/1.0
    ne peut être utilisée que si la taille du contenu est connue
    d'avance. Ceci implique que les contenus dynamiques comme les
    sorties CGI, les pages SSI, et les listings de répertoires générés
    par le serveur n'utiliseront en général pas les connexions
    persistantes avec les clients HTTP/1.0. Avec les clients HTTP/1.1,
    les connexions persistantes sont utilisées par défaut, sauf
    instructions contraires. Si le client le demande, le transfert par
    tronçons de taille fixe (chunked encoding) sera utilisé afin de
    transmettre un contenu de longueur inconnue via une connexion
    persistante.
    

    
    Lorsqu'un client utilise une connexion persistante, elle comptera
    pour une seule requête pour la directive MaxConnectionsPerChild, quel
    que soit le nombre de requêtes transmises via cette connexion.

    Le nombre de secondes pendant lesquelles Apache httpd va attendre une
    requête avant de fermer la connexion. Le délai peut être défini en
    millisecondes en suffixant sa valeur par ms. La valeur du délai
    spécifiée par la directive Timeout s'applique dès qu'une requête a
    été reçue.
    

    
    Donner une valeur trop élévée à
    KeepAliveTimeout peut induire des problèmes
    de performances sur les serveurs fortement chargés. Plus le délai
    est élévé, plus nombreux seront les processus serveur en attente de
    requêtes de la part de clients inactifs.
    

    
    Si la directive KeepAliveTimeout n'est
    pas définie pour un serveur virtuel à base de nom, c'est
    la valeur de la paire adresse IP/port du serveur virtuel qui
    correspond le mieux qui sera utilisée.

    Directive <Limit>
    

    

    Description:Limite les contrôles d'accès que la section contient à
certaines méthodes HTTP
    

    Syntaxe:<Limit méthode [méthode] ... > ...
    </Limit>
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig, Limit
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Les contrôles d'accès s'appliquent normalement à
    toutes les méthodes d'accès, et c'est en général le
    comportement souhaité. Dans le cas général, les directives
    de contrôle d'accès n'ont pas à être placées dans une section
    <Limit>.
    

    
    La directive <Limit> a pour
    but de limiter les effets des contrôles d'accès aux méthodes HTTP
    spécifiées. Pour toutes les autres méthodes, les restrictions
    d'accès contenues dans la section <Limit> n'auront aucun
    effet. L'exemple suivant n'applique les contrôles d'accès
    qu'aux méthodes POST, PUT, et
    DELETE, en laissant les autres méthodes sans protection
    :
    

    
    <Limit POST PUT DELETE>
  Require valid-user
</Limit>
    


    
    La liste des noms de méthodes peut contenir une ou plusieurs
    valeurs parmi les suivantes : GET, POST,
    PUT, DELETE, CONNECT,
    OPTIONS, PATCH, PROPFIND,
    PROPPATCH, MKCOL, COPY,
    MOVE, LOCK, et UNLOCK.
    Le nom de méthode est sensible à la casse. Si la
    valeur GET est présente, les requêtes HEAD
    seront aussi concernées. La méthode TRACE ne peut pas
    être limitée (voir la directive TraceEnable).
    

    
    Une section <LimitExcept> doit toujours être préférée à
    une section <Limit> pour la
    restriction d'accès, car une section <LimitExcept> fournit une protection contre
    les méthodes arbitraires.
    

    
    Les directives <Limit> et
    <LimitExcept>
    peuvent être imbriquées. Dans ce cas, pour chaque niveau des
    directives <Limit> ou  <LimitExcept>, ces dernières
    doivent restreindre l'accès pour les méthodes auxquelles les
    contrôles d'accès s'appliquent.
    

    
    Lorsqu'on utilise les directives <Limit> ou <LimitExcept> avec la directive Require, la première directive
    Require dont la
    condition est satisfaite autorise la requête, sans tenir compte de
    la présence d'autres directives Require.
    

    
    Par exemple, avec la configuration suivante, tous les
    utilisateurs seront autorisés à effectuer des requêtes
    POST, et la directive Require group
    editors sera ignorée dans tous les cas :
    

    
    <LimitExcept GET>
  Require valid-user
</LimitExcept>
<Limit POST>
  Require group editors
</Limit>

    opposé à celui de la section <Limit>, et on peut les utiliser pour
    contrôler aussi bien les méthodes standards que les méthodes non
    standards ou non reconnues. Voir la documentation de la section
    <Limit> pour plus
    de détails.

    Directive LimitInternalRecursion
    

    

    Description:Détermine le nombre maximal de redirections internes et de
sous-requêtes imbriquées
    

    Syntaxe:LimitInternalRecursion nombre [nombre]
    

    Défaut:LimitInternalRecursion 10
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Une redirection interne survient, par exemple, quand on utilise
    la directive Action qui
    redirige en interne la requête d'origine vers un script CGI. Une
    sous-requête est le mécanisme qu'utilise Apache httpd pour déterminer ce
    qui se passerait pour un URI s'il faisait l'objet d'une requête. Par
    exemple, mod_dir utilise les sous-requêtes pour
    rechercher les fichiers listés dans la directive DirectoryIndex.
    

    
    La directive LimitInternalRecursion permet
    d'éviter un crash du serveur dû à un bouclage infini de redirections
    internes ou de sous-requêtes. De tels bouclages sont dus en général
    à des erreurs de configuration.
    

    
    La directive accepte, comme arguments, deux limites qui sont
    évaluées à chaque requête. Le premier nombre est le
    nombre maximum de redirections internes qui peuvent se succéder. Le
    second nombre détermine la profondeur d'imbrication
    maximum des sous-requêtes. Si vous ne spécifiez qu'un seul
    nombre, il sera affecté aux deux limites.

    Module:core
    

    
    
    Cette directive spécifie la taille maximale autorisée pour le
    corps d'une requête ; la valeur de l'argument octets va
    de 0 (pour une taille illimitée), à 2147483647 (2Go). Voir la note
    ci-dessous pour la limite d'applicabilité aux requêtes mandatées.
    

    
    La directive LimitRequestBody permet de
    définir une limite pour la taille maximale autorisée du corps d'une
    requête HTTP en tenant compte du contexte dans lequel la directive
    a été placée (c'est à dire au niveau du serveur, d'un répertoire,
    d'un fichier ou d'une localisation). Si la requête du client dépasse
    cette limite, le serveur répondra par un message d'erreur et ne
    traitera pas la requête. La taille du corps d'une requête normale va
    varier de manière importante en fonction de la nature de la
    ressource et des méthodes autorisées pour cette dernière. Les
    scripts CGI utilisent souvent le corps du message pour extraire les
    informations d'un formulaire. Les implémentations de la méthode
    PUT nécessitent une valeur au moins aussi élevée que la
    taille maximale des représentations que le serveur désire accepter
    pour cette ressource.
    

    
    L'administrateur du serveur peut utiliser cette directive pour
    contrôler plus efficacement les comportements anormaux des requêtes
    des clients, ce qui lui permettra de prévenir certaines formes
    d'attaques par déni de service.
    

    
    Si par exemple, vous autorisez le chargement de fichiers vers une
    localisation particulière, et souhaitez limiter la taille des
    fichiers chargés à 100Ko, vous pouvez utiliser la directive suivante
    :
    

    
    LimitRequestBody 102400
    


    
    Pour une description détaillée de la manière dont cette
    directive est interprétée par les requêtes mandatées, voir la
    documentation du module mod_proxy.

    nombre est un entier de 0 à 32767. La valeur 0 signifie un
    nombre de champs illimité. La valeur par défaut est définie à la compilation
    par la constante DEFAULT_LIMIT_REQUEST_FIELDS (100 selon la
    distribution).
    

    
    La directive LimitRequestFields permet à
    l'administrateur du serveur de modifier le nombre maximum de champs
    d'en-tête autorisés dans une requête HTTP. Pour un serveur, cette
    valeur doit être supérieure au nombre de champs qu'une requête
    client normale peut contenir. Le nombre de champs d'en-tête d'une
    requête qu'un client utilise dépasse rarement 20, mais ce nombre
    peut varier selon les implémentations des clients, et souvent en
    fonction des extensions que les utilisateurs configurent dans leurs
    navigateurs pour supporter la négociation de contenu détaillée. Les
    extensions HTTP optionnelles utilisent souvent les
    champs d'en-tête des requêtes.
    

    
    L'administrateur du serveur peut utiliser cette directive pour
    contrôler plus efficacement les comportements anormaux des requêtes
    des clients, ce qui lui permettra de prévenir certaines formes
    d'attaques par déni de service. La valeur spécifiée doit être
    augmentée si les clients standards reçoivent une erreur du serveur
    indiquant que la requête comportait un nombre d'en-têtes trop
    important.
    

    
    Par exemple :
    

    
    LimitRequestFields 50

    La directive LimitRequestFieldSize permet
    à l'administrateur du serveur de définir la taille
    maximale autorisée d'un en-tête de requête HTTP. Pour un serveur,
    cette valeur doit être suffisamment grande pour contenir tout
    en-tête d'une requête client normale. La taille d'un champ d'en-tête
    de requête normal va varier selon les implémentations des clients,
    et en fonction des extensions que les utilisateurs
    configurent dans leurs navigateurs pour supporter la négociation de
    contenu détaillée. Les en-têtes d'authentification SPNEGO peuvent
    atteindre une taille de 12392 octets.

    La directive LimitRequestLine permet à
    l'administrateur du serveur de définir la taille
    maximale autorisée d'une ligne de requête HTTP client. Comme une
    requête comporte une méthode HTTP, un URI, et une version de
    protocole, la directive LimitRequestLine
    impose une restriction sur la longueur maximale autorisée pour un
    URI dans une requête au niveau du serveur. Pour un serveur, cette
    valeur doit être suffisamment grande pour référencer les noms de
    toutes ses ressources, y compris toutes informations pouvant être
    ajoutées dans la partie requête d'une méthode GET.

    Directive <Location>
    

    

    Description:N'applique les directives contenues qu'aux URLs
spécifiées
    

    Syntaxe:<Location
    chemin URL|URL> ... </Location>
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La directive <Location>
    limite la portée des directives contenues aux URLs définies par
    l'argument URL. Elle est similaire à la directive <Directory>, et marque le
    début d'une section qui se termine par une directive
    </Location>. Les sections <Location> sont traitées selon l'ordre dans
    lequel elles apparaissent dans le fichier de configuration, mais
    après les sections <Directory> et la lecture des
    fichiers .htaccess, et après les sections <Files>.
    

    
    Les sections <Location>
    agissent complètement en dehors du système de fichiers. Ceci a de
    nombreuses conséquences. Parmi les plus importantes, on ne doit pas
    utiliser les sections <Location>
    pour contrôler l'accès aux répertoires du système de fichiers. Comme
    plusieurs URLs peuvent correspondre au même répertoire du système de
    fichiers, un tel contrôle d'accès pourrait être contourné.
    

    
    Les directives que contient cette section seront appliquées aux
    requêtes si la partie chemin de l'URL satisfait à l'un au moins de
    ces critères :
    
    
    
      
      
    • Le chemin spécifié correspond exactement à la partie chemin de
      l'URL.
      
      • 
      
    • Le chemin spécifié, qui se termine par un slash, est un
      préfixe de la partie chemin de l'URL (traité comme une racine du
      contexte).
      
      • 
      
    • Le chemin spécifié, si on lui ajoute un slash de fin, est un
      préfixe de la partie chemin de l'URL (aussi traité comme une racine du
      contexte).
      
      • 
    
    
    
    
    Dans l'exemple ci-dessous, où aucun slash de fin n'est utilisé, les
    directives contenues dans la section s'appliqueront à /private1,
    /private1/ et /private1/file.txt, mais pas à /private1other. 
    
    
    
    <Location "/private1">
    #  ...
</Location>
    

    
    
    De même, dans l'exemple ci-dessous, où l'on utilise un slash de fin, les
    directives contenues dans la section s'appliqueront à /private2/ et
    à /private2/file.txt, mais pas à /private2other.
    
    
    
    <Location "/private2/">
    # ...
</Location>
    

    
    
    Quand utiliser la section <Location>
    

    
    Vous pouvez utiliser une section <Location> pour appliquer des directives à
    des contenus situés en dehors du système de fichiers. Pour les
    contenus situés à l'intérieur du système de fichiers, utilisez
    plutôt les sections <Directory> et <Files>. <Location
    "/"> constitue une exception et permet d'appliquer aisément
    une configuration à l'ensemble du serveur.
    
    
    

    
    Pour toutes les requêtes originales (non mandatées), l'argument
    URL est un chemin d'URL de la forme
    /chemin/. Aucun protocole, nom d'hôte, port, ou chaîne
    de requête ne doivent apparaître. Pour les requêtes mandatées, l'URL
    spécifiée doit être de la forme
    protocole://nom_serveur/chemin, et vous devez inclure
    le préfixe.
    

    
    L'URL peut contenir des caractères génériques. Dans une chaîne
    avec caractères génériques, ? correspond à un caractère
    quelconque, et * à toute chaîne de caractères. Les
    caractères génériques ne peuvent pas remplacer un / dans le chemin
    URL.
    

    
    On peut aussi utiliser les Expressions
    rationnelles, moyennant l'addition d'un caractère
    ~. Par exemple :
    

    
    <Location ~ "/(extra|special)/data">
    #...
</Location>
    


    
    concernerait les URLs contenant les sous-chaîne
    /extra/data ou /special/data. La directive
    <LocationMatch>
    présente un comportement identique à la version avec expressions
    rationnelles de la directive <Location>, et son utilisation est
    préférable à l'utilisation de cette dernière pour la simple raison
    qu'il est difficile de distinguer ~ de -
    dans la plupart des fontes.
    

    
    La directive <Location>
    s'utilise principalement avec la directive SetHandler. Par exemple, pour activer les
    requêtes d'état, mais ne les autoriser que depuis des navigateurs
    appartenant au domaine example.com, vous pouvez
    utiliser :
    

    
    <Location "/status">
  SetHandler server-status
  Require host example.com
</Location>
    


      
    Note à propos du slash (/)
     
    La signification du
    caractère slash dépend de l'endroit où il se trouve dans l'URL. Les
    utilisateurs peuvent être habitués à son comportement dans le système de
    fichiers où plusieurs slashes successifs sont souvent réduits à un slash
    unique (en d'autres termes, /home///foo est identique à
    /home/foo). Dans l'espace de nommage des URLs, ce n'est
    cependant pas toujours vrai si la directive MergeSlashes a été définie à "OFF". Pour la
    directive <LocationMatch>
    et la version avec expressions rationnelles de la directive <Location>, vous devez spécifier explicitement les
    slashes multiples si les slashes ne sont pas fusionnés.
    

      
    Par exemple, <LocationMatch "^/abc"> va
      correspondre à l'URL /abc mais pas à l'URL 
      //abc. La directive <Location> sans expression rationnelle se comporte de
      la même manière lorsqu'elle est utilisée pour des requêtes
      mandatées. Par contre, lorsque la directive <Location> sans expression rationnelle
      est utilisée pour des requêtes non mandatées, elle fera
      correspondre implicitement les slashes multiples à des slashes
      uniques. Par exemple, si vous spécifiez <Location
      "/abc/def">, une requête de la forme
      /abc//def correspondra.

    chaîne de caractères. Par exemple :
    

    
    <LocationMatch "/(extra|special)/data">
    # ...
</LocationMatch>
    


    
    correspondrait à toute URL contenant les sous-chaînes
    /extra/data ou /special/data.
    

    
    Si vous recherchez une URL commençant par
    plutôt que seulement contenant /extra/data, préfixez
    l'expression rationnelle avec un ^.

    par "MATCH_". Ceci permet
    de référencer des URLs dans des expressions
    ou au sein de modules comme mod_rewrite. Pour
    éviter toute confusion, les références arrières numérotées (non
    nommées) sont ignorées. Vous devez utiliser à la place des groupes

    caractère slash '/' dépend de l'endroit où il apparaît dans une URL. Les
    utilisateurs sont habitués à voir de multiples slashes adjacents réduits à
    un seul au sein du système de fichiers (par exemple,
    /home///foo est équivalent à /home/foo). Ce n'est
    n'est cependant pas toujours vrai au sein des URLs si la directive
    MergeSlashes a été définie à "OFF". En
    effet, si vous souhaitez spécifier plusieurs slashes, vous devez le faire
    explicitement au sein de la directive <LocationMatch> et de la version regex de la
    directive <Location>, si les slashes ne
    sont pas fusionnés.
    

      
    Par exemple, <LocationMatch "^/abc"> correspondra à
      l'URL /abc, mais pas à l'URL //abc. La directive
      (non-regex) <Location> se comporte de
      la même manière lorsqu'elle est utilisée dans les requêtes de mandataire.
      Par contre, pour les autres types de requêtes, la directive <Location> considérera plusieurs slashes
      adjacents comme équivalents à un seul slash. Par exemple, si vous
      spécifiez <Location "/abc/def">, une requête pour
      /abc//def correspondra.

    Directive LogLevel
    

    

    Description:Contrôle la verbosité du journal des erreurs
    

    Syntaxe:LogLevel [module:]niveau
    [module:niveau] ...

    

    Défaut:LogLevel warn

    La directive LogLevel permet d'ajuster la
    verbosité des messages enregistrés dans les journaux d'erreur (voir
    la directive ErrorLog
    directive). Les niveaux disponibles sont présentés
    ci-après, par ordre de criticité décroissante :
    

    
    
    
      
    
        Niveau 

        Description 

        Exemple

        Messages de débogage.

        "Opening config file ..."

	données

    Lorsqu'un niveau particulier est spécifié, les messages de tous
    les autres niveaux de criticité supérieure seront aussi enregistrés.
    Par exemple, si LogLevel info est spécifié,
    les messages de niveaux notice et warn
    seront aussi émis.
    

    
    Il est recommandé d'utiliser un niveau crit ou
    inférieur.
    

    
    Par exemple :
    

    
    LogLevel notice
    


    
    Note
    
      
    Si la journalisation s'effectue directement dans un fichier,
      les messages de niveau notice ne peuvent pas être
      supprimés et sont donc toujours journalisés. Cependant, ceci ne
      s'applique pas lorsque la journalisation s'effectue vers
      syslog.
    
    
    
    
    
    Spécifier un niveau sans nom de module va attribuer ce niveau à
    tous les modules. Spécifier un niveau avec nom de module va
    attribuer ce niveau à ce module seulement. Il est possible de
    spécifier un module par le nom de son fichier source ou par son
    identificateur, avec ou sans le suffixe _module. Les
    trois spécifications suivantes sont donc équivalentes :
    

    
    LogLevel info ssl:warn
LogLevel info mod_ssl.c:warn
LogLevel info ssl_module:warn
    


    
    Il est aussi possible d'attribuer un niveau de journalisation par
    répertoire :
    

    
    LogLevel info
<Directory "/usr/local/apache/htdocs/app">
  LogLevel debug
</Directory>
    


    
    
        La configuration du niveau de journalisation par répertoire
	n'affecte que les messages journalisés après l'interprétation de
	la requête et qui sont associés à cette dernière. Les messages
	de journalisation associés à la connexion ou au serveur ne sont
	pas affectés.

    Module:core
    

    Compatibilité:Disponible à partir de la version 2.4.39 du serveur HTTP Apache
    

    
    
    Par défaut, le serveur fusionne les caractères slash ('/') multiples et
    consécutifs dans la partie chemin de l'URL d'une requête.
    

    
    Lorsque cette partie chemin de l'URL est appliquée au système de
    fichiers, ces slashes multiples sont inutiles. Il peut être cependant
    préférable de conserver ces slashes multiples et consécutifs car ils peuvent
    avoir une signification dans le cas des URLs gérées différemment, par
    exemple par CGI ou par un serveur mandataire. Il convient alors de définir
    MergeSlashes à OFF pour conserver les
    slashes multiples consécutifs, ce qui correspond au comportement
    traditionnel.
    
    
    
    Lorsque cette directive est définie à "OFF", les expressions rationnelles utilisées dans le
    fichier de configuration pour effectuer une comparaison de la partie chemin
    de l'URL ((LocationMatch,
    RewriteRule, ...) doivent en effet tenir compte de la
    présence éventuelle de slashes multiples et consécutifs. Les sections
    Location à base d'expressions non rationnelles
    correspondent toujours à des URLs avec slashes fusionnés et ne peuvent pas
    tenir compte des slashes multiples.

    Cette directive permet de contrôler la fusion des données HTTP
    supplémentaires (trailers) avec la représentation interne des

    modifier les en-têtes de la requête.
    
    
    Cette option a été introduite dans un souci de compatibilité avec

    Module:core
    

    Compatibilité:Disponible depuis la version 2.3.4 du serveur HTTP Apache
    

    
    
    La directive Mutex permet de définir le
    mécanisme de mutex, et éventuellement le répertoire du fichier
    verrou que les modules et httpd utilisent pour sérialiser l'accès aux
    ressources. Spécifiez default comme second argument
    pour modifier la configuration de tous les mutex ; spécifiez un nom
    de mutex (voir la table ci-dessous) comme second argument pour
    ne modifier que la configuration de ce mutex.
    

    
    La directive Mutex est typiquement
    utilisée dans les situations exceptionnelles suivantes :
    

    
      
        
    • choix d'un autre mécanisme de mutex lorsque le mécanisme par
	défaut sélectionné par APR présente un
	problème de fonctionnement ou de performances.
      • 

        
    • choix d'un autre répertoire utilisé par les mutex à base de
	fichier lorsque le répertoire par défaut ne supporte pas le
	verrouillage
      • 
    
    

    
    Modules supportés
    
    
    Cette directive ne configure que les mutex qui ont été
    enregistrés avec le serveur de base via l'API
    ap_mutex_register(). Tous les modules fournis avec
    httpd supportent la directive Mutex, mais il
    n'en sera pas forcément de même pour les modules tiers.
    Reportez-vous à la documentation du module tiers considéré afin de
    déterminer le(s) nom(s) de mutex qui pourront être définis si la
    directive est supportée.
    
    
    

    

    
    Les mécanismes de mutex disponibles sont les suivants :
    
    
      
        
    • default | yes
        
      C'est l'implémentation du verrouillage par défaut, telle
	qu'elle est définie par APR. On peut
	afficher l'implémentation du verrouillage par défaut via la
	commande httpd avec l'option -V.
      • 

        
    • none | no
        
      Le mutex est désactivé, et cette valeur n'est permise pour un
	mutex que si le module indique qu'il s'agit d'un choix valide.
	Consultez la documentation du module pour plus d'informations.
      • 

        
    • posixsem
        
      Une variante de mutex basée sur un sémaphore Posix.
      

        
      Avertissement
      
        
      La propriété du sémaphore n'est pas restituée si un thread du
	processus gérant le mutex provoque une erreur de segmentation,
	ce qui provoquera un blocage du serveur web.
      
        
      
        
      • 

        
    • sysvsem
        
      Une variante de mutex basée sur un sémaphore IPC SystemV.
      

        
      Avertissement
      
        
      Il peut arriver que les sémaphores SysV soient conservés si le
	processus se crashe avant que le sémaphore ne soit supprimé.
      
	
      

        
      Sécurité
      
        
      L'API des sémaphores permet les attaques par déni de service
	par tout programme CGI s'exécutant sous le même uid que le
	serveur web (autrement dit tous les programmes CGI, à moins que
	vous n'utilisiez un programme du style suexec
	ou cgiwrapper).

    • sem
        
      Sélection de la "meilleure" implémentation des sémaphores
	disponible ; le choix s'effectue entre les sémaphores posix et
	IPC SystemV, dans cet ordre.
      • 

        
    • pthread
        
      Une variante de mutex à base de mutex de thread Posix
	inter-processus.
      

        
      Avertissement
      
        
      Sur la plupart des systèmes, si un processus enfant se
	termine anormalement alors qu'il détenait un mutex qui utilise
	cette implémentation, le serveur va se bloquer et cesser de
	répondre aux requêtes. Dans ce cas, un redémarrage manuel est
	nécessaire pour récupérer le mutex.
      
        
      Solaris et Linux constituent des exceptions notables, en ceci qu'ils	fournissent
	un mécanisme qui permet en général de récupérer le mutex après
	l'arrêt anormal d'un processus enfant qui détenait le mutex.
      
        
      Si votre système est compatible POSIX ou implémente la fonction
	pthread_mutexattr_setrobust_np(), vous devriez
	pouvoir utiliser l'option pthread sans problème.
      
        
      
        
      • 

        
    • fcntl:/chemin/vers/mutex
        
      Une variante de mutex utilisant un fichier verrou physique et
	la fonction fcntl().
      

        
      Avertissement
      
        
      Lorsqu'on utilise plusieurs mutex basés sur ce mécanisme dans
	un environnement multi-processus, multi-thread, des erreurs de
	blocage (EDEADLK) peuvent être rapportées pour des opérations de
	mutex valides si la fonction fcntl() ne gère pas
	les threads, comme sous Solaris.

    • file:/chemin/vers/mutex
        
      Sélection de la "meilleure" implémentation de verrouillage

	fcntl et flock, dans cet ordre.
      • 
    
    

    
    La plupart des mécanismes ne sont disponibles que sur les
    plate-formes où ces dernières et APR les
    supportent. Les mécanismes qui ne sont pas disponibles sur toutes
    les plate-formes sont posixsem,
    sysvsem, sem, pthread, fcntl, 
    flock, et file.
    

    
    Avec les mécanismes à base de fichier fcntl et
    flock, le chemin, s'il est fourni, est un répertoire dans
    lequel le fichier verrou sera créé. Le répertoire par
    défaut est le répertoire d'exécution de httpd relatif à la
    directive ServerRoot.
    Utilisez toujours un système
    de fichiers local sur disque pour /chemin/vers/mutex et
    jamais un répertoire se trouvant dans un système de fichiers NFS ou
    AFS. Le nom de base du fichier se composera du type de mutex, d'une
    chaîne optionnelle correspondant à l'instance et fournie par le
    module ; et, sauf si le mot-clé OmitPID a été spécifié,
    l'identificateur du processus parent httpd sera ajouté afin de
    rendre le nom du fichier unique, évitant ainsi tout conflit lorsque
    plusieurs instances d'httpd partagent le même répertoire de
    verrouillage. Par exemple, si le nom de mutex est
    mpm-accept, et si le répertoire de verrouillage est
    /var/httpd/locks, le nom du fichier verrou pour
    l'instance httpd dont le processus parent a pour identifiant 12345
    sera /var/httpd/locks/mpm-accept.12345.
    

    
    Sécurité
    
    
    Il est conseillé d'éviter de placer les fichiers mutex
    dans un répertoire où tout le monde peut écrire comme
    /var/tmp, car quelqu'un pourrait initier une attaque
    par déni de service et empêcher le serveur de démarrer en créant un
    fichier verrou possédant un nom identique à celui que le serveur va
    tenter de créer.
    
    
    

    
    La table suivante décrit les noms de mutex utilisés par httpd et
    ses modules associés.

    Le mot-clé OmitPID permet d'empêcher l'addition de
    l'identifiant du processus httpd parent au nom du fichier verrou.
    


    
    Dans l'exemple suivant, le mécanisme de mutex pour le mutex
    mpm-accept est modifié pour passer du mécanisme par défaut au
    mécanisme fcntl, avec le fichier verrou associé créé
    dans le répertoire /var/httpd/locks. Le mécanisme de
    mutex par défaut pour tous les autres mutex deviendra
    sysvsem.
    

    
    Mutex sysvsem default
Mutex fcntl:/var/httpd/locks mpm-accept

    Avant la version 2.3.11, il était nécessaire de définir une
    directive NameVirtualHost pour indiquer au
    serveur qu'une paire adresse IP/port particulière pouvait être
    utilisée comme serveur virtuel à base de nom. Depuis la version
    2.3.11, chaque fois qu'une paire adresse IP/port est utilisée dans
    plusieurs serveurs virtuels, l'hébergement virtuel à base de nom est
    automatiquement activé pour cette adresse.
    
    
    
    Cette directive n'a actuellement plus aucun effet.

    Directive Options
    

    

    Description:Définit les fonctionnalités disponibles pour un répertoire
particulier
    

    Syntaxe:Options
    [+|-]option [[+|-]option] ...
    

    Défaut:Options FollowSymlinks
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Options
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Avec la version 2.3.11, la valeur par défaut passe de All
à FollowSymlinks
    

    
    
    La directive Options permet de définir
    les fonctionnalités de serveur disponibles pour un répertoire
    particulier.
    

    
    option peut être défini à None, auquel
    cas aucune fonctionnalité spécifique n'est activée, ou comprendre
    une ou plusieurs des options suivantes :
    

    
    
      
    All
    

      
    Toutes les options excepté MultiViews.
    

      
    ExecCGI
    

      
    L'exécution de scripts CGI à l'aide du module
      mod_cgi est permise.
    

      
    FollowSymLinks
    

      
    

      Le serveur va suivre les liens symboliques dans le répertoire
      concerné. Il s'agit de la valeur par défaut.
      
    
      
    Bien que le serveur suive les liens symboliques, il ne modifie
      pas le nom de chemin concerné défini par la section
      <Directory>.
    
      
      
    Les options FollowSymLinks et
      SymLinksIfOwnerMatch ne fonctionnent que dans les
      sections <Directory> ou les fichiers
      .htaccess.
    

      
    Le fait d'omettre cette option ne doit pas être considéré comme
      une mesure de sécurité efficace, car il existe toujours une
      situation de compétition (race condition) entre l'instant où l'on
      vérifie qu'un chemin n'est pas un lien symbolique, et l'instant où
      l'on utilise effectivement ce chemin.
    
      
    

      
    Includes
    

      
    
      Les inclusions côté serveur (SSI) à l'aide du module
      mod_include sont autorisées.
    

      
    IncludesNOEXEC
    

      
    

      Les inclusions côté serveur (SSI) sont permises, mais #exec
      cmd et #exec cgi sont désactivés.
      L'utilisation de #include virtual pour les scripts
      CGI est cependant toujours possible depuis des répertoires
      définis par ScriptAlias.
    

      
    Indexes
    

      
    
      Si une URL requise correspond au répertoire concerné, et si aucun
      DirectoryIndex (par
      exemple index.html) n'est défini pour ce
      répertoire, le module mod_autoindex va renvoyer
      un listing formaté du répertoire.
    

      
    MultiViews
    

      
    
      Les vues multiples ("multiviews") à contenu négocié à l'aide du
      module mod_negotiation sont autorisées.
      
    Note
     
    Cette option est ignorée si elle est
      définie en tout autre endroit qu'une section <Directory>, car
      mod_negotiation a besoin de ressources réelles
      pour effectuer ses comparaisons et ses évaluations.
    
      
      
    

      
    SymLinksIfOwnerMatch
    

      
    Le serveur ne suivra que les liens symboliques qui renvoient
      vers un fichier ou un répertoire dont le propriétaire est le même
      que celui du lien.

      
    Note
    
      
    Les options FollowSymLinks et
      SymLinksIfOwnerMatch ne fonctionnent que dans les
      sections <Directory> ou les fichiers
      .htaccess.
    

      
    Le fait d'omettre cette option ne doit pas être considéré comme
      une mesure de sécurité efficace, car il existe toujours une
      situation de compétition (race condition) entre l'instant où l'on
      vérifie qu'un chemin n'est pas un lien symbolique, et l'instant où
      l'on utilise effectivement ce chemin.
    
      
     
    
    
    

    
    Normalement, si plusieurs directives
    Options peuvent s'appliquer à un répertoire,
    c'est la plus spécifique qui est utilisée et les autres sont
    ignorées ; les options ne sont pas fusionnées (voir comment les sections sont
    fusionnées). Elles le sont cependant si toutes les
    options de la directive Options sont
    précédées d'un symbole + ou -. Toute
    option précédée d'un + est ajoutée à la liste des
    options courantes de manière forcée et toute option précédée d'un
    - est supprimée de la liste des options courantes de la
    même manière.
    

    
    Note
    
    
    Mélanger des Options avec +
    ou - avec des Options sans
    + ou - constitue une erreur de syntaxe, et
    la vérification de la syntaxe au cours du démarrage du serveur fera
    échouer ce dernier.
    
    
    

    
    Par exemple, sans aucun symbole + et -
    :
    

    
    <Directory "/web/docs">
  Options Indexes FollowSymLinks
</Directory>

<Directory "/web/docs/spec">
  Options Includes
</Directory>
    


    
    ici, seule l'option Includes sera prise en compte
    pour le répertoire /web/docs/spec. Par contre, si la
    seconde directive Options utilise les
    symboles + et - :
    

    
    <Directory "/web/docs">
  Options Indexes FollowSymLinks
</Directory>

<Directory "/web/docs/spec">
  Options +Includes -Indexes
</Directory>
    


    
    alors, les options FollowSymLinks et
    Includes seront prises en compte pour le répertoire
    /web/docs/spec.
    

    
    Note
    
      
    L'utilisation de -IncludesNOEXEC ou
      -Includes désactive complètement les inclusions côté
      serveur sans tenir compte des définitions précédentes.
    
    
    

    
    En l'absence de toute définition d'options, la valeur par défaut
    est FollowSymlinks.

    Directive Protocol
    

    

    Description:Protocole pour une socket d'écoute
    

    Syntaxe:Protocol protocole
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Disponible depuis la version 2.1.5 d'Apache, mais
seulement depuis la version 2.3.3 sous Windows.
    

    
    
    Cette directive permet de spécifier le protocole utilisé pour une
    socket d'écoute particulière. Le protocole sert à déterminer quel
    module doit traiter une requête, et d'appliquer les optimisations
    spécifiques au protocole via la directive
    AcceptFilter.
    

    
    Dans la plupart des configurations, cette directive n'est pas nécessaire.
    Si elle n'est pas définie, le protocole par défaut pour le port 443 est
    https et http pour tous les autres ports. La
    connaissance du protocole permet de déterminer quel module doit traiter la
    requête, et d'appliquer les optimisations spécifiques au protocole via la
    directive AcceptFilter.
    

    
    Par exemple, si vous travaillez avec le protocole
    https sur un port non standard, spécifiez le protocole
    de manière explicite :
    

    
    Protocol https
    


    
    Vous pouvez aussi spécifier le protocole via la directive
    Listen.

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Disponible à partir de la version 2.4.17 du serveur
    HTTP Apache.
    

    
        
    Cette directive permet de spécifier la liste des protocoles
	supportés par un serveur virtuel ou non. Cette liste énumère les
	protocoles qu'un client sera autorisé à négocier avec ce
	serveur.
    
        
        
    Par défaut,
	seul le	protocole http/1.1 est disponible (compatible avec les
	clients http/1.0 et http/0.9). Par conséquent, vous devez
	fournir cette liste si vous voulez étendre les protocoles
	disponibles pour le serveur.
    
        
        
    Par exemple, si vous voulez autoriser le protocole
	HTTP/2 pour un serveur avec TLS, utilisez
	cette directive comme suit :
    
        
        
    Protocols h2 http/1.1
    


        
    Les protocoles valides sont http/1.1 pour les
	connexions http et https, h2 pour les connections
	https et h2c pour les connexions http. D'autres
	modules peuvent fournir d'autres protocoles.
    
        
        
    Spécifier des protocoles non disponibles ou désactivés n'aura
	aucun effet, et ceux-ci seront simplement ignorés.
    
        
        
    Si un serveur virtuel ne possède pas de directive Protocols
	propre, il hérite des protocoles spécifiés pour le serveur
	principal. Autrement dit, les directives Protocols définies au
	niveau d'un serveur virtuel remplacent celles définies au niveau
	du serveur principal.

    Cette directive permet de définir si le serveur doit tenir
	compte de l'ordre des protocoles définis par la directive
	Protocols.
    
        
        
    Si cette directive est définie à Off, l'ordre de la liste des
	protocoles fournie par le client l'emporte sur l'ordre défini
	dans la configuration du serveur.
    
        
        
    Si la directive ProtocolsHonorOrder
	est définie à on (valeur par défaut),
	il n'est pas tenu compte de l'ordre de la liste des protocoles
	fournie par le client, et seul l'ordre de la liste des protocles
	définie au niveau du serveur influera la
	négociation du protocole.

serveur HTTP Apache. Jusqu'à la version 2.4.17, le serveur se comportait
comme si la directive QualifyRedirectURL était définie à On.
    

    
    
    Cette directive permet de s'assurer que le serveur vérifiera que
    la variable d'environnement REDIRECT_URL est bien pleinement
    qualifiée. Par défaut, cette variable contient l'URL textuellement
    demandée par le client, par exemple "/index.html". Avec
    QualifyRedirectURL ON, la même requête
    affectera à la variable REDIRECT_URL une valeur du style
    "http://www.example.com/index.html".
    
    
    Même si cette directive n'est pas définie, lorsqu'une requête est
    soumise avec une URL pleinement qualifiée, la variable REDIRECT_URL
    contiendra quand-même une URL pleinement qualifiée.

    Module:core
    

    Compatibilité:Win32 seulement.
    

    
    
    Cette directive permet de contrôler la méthode qu'utilise Apache
    httpd pour trouver l'interpréteur destiné à exécuter les scripts CGI. La
    définition par défaut est Script : ceci indique à
    Apache httpd qu'il doit utiliser l'interpréteur précisé dans la ligne
    shebang du script (la première ligne, commençant par
    #!). Sur les systèmes Win32, cette ligne ressemble
    souvent à ceci :
    

    
    #!C:/Perl/bin/perl.exe
    


    
    ou simplement, dans le cas où perl est dans le
    PATH :
    

    
    #!perl
    


    
    Avec ScriptInterpreterSource Registry, Windows va
    effectuer une recherche dans l'arborescence
    HKEY_CLASSES_ROOT de la base de registre avec comme
    mot-clé l'extension du fichier contenant le script (par exemple
    .pl). C'est la commande définie par la sous-clé de
    registre Shell\ExecCGI\Command ou, si elle n'existe
    pas, la sous-clé Shell\Open\Command qui est utilisée
    pour ouvrir le fichier du script. Si ces clés de registre ne sont
    pas trouvées, Apache httpd utilise la méthode de l'option
    Script.
    

    
    Sécurité
    
    
    Soyez prudent si vous utilisez ScriptInterpreterSource
    Registry avec des répertoires faisant l'objet d'un ScriptAlias, car Apache httpd va essayer
    d'exécuter tous les fichiers contenus dans
    celui-ci. L'option Registry peut causer des appels de
    programmes non voulus sur des fichiers non destinés à être exécutés.
    Par exemple, la commande par défaut open sur les fichiers
    .htm sur la plupart des systèmes Windows va lancer
    Microsoft Internet Explorer ; ainsi, toute requête HTTP pour un
    fichier .htm situé dans le répertoire des scripts
    va lancer le navigateur en arrière-plan sur le serveur, ce qui a
    toutes les chances de crasher votre système dans les minutes qui
    suivent.
    
    
    

    
    L'option Registry-Strict
    agit de manière identique à Registry, mais n'utilise
    que la sous-clé Shell\ExecCGI\Command. La présence de
    la clé ExecCGI n'étant pas systématique, Elle doit être
    définie manuellement dans le registre Windows et évite ainsi tout
    appel de programme accidentel sur votre système.

    Avec ExtendedStatus On, mod_status affiche la
    véritable requête en cours de traitement. Pour des raisons
    historiques, seuls 63 caractères de la requête sont réellement
    stockés à des fins d'affichage. Cette directive permet de déterminer
    si ce sont les 63 premiers caractères qui seront stockés (c'est le
    comportement par défaut),
    ou si ce sont les 63 derniers. Ceci ne s'applique bien entendu que
    si la taille de la requête est de 64 caractères ou plus.
    

    
    Si Apache httpd traite la requête GET /disque1/stockage/apache/htdocs/images/rep-images1/nourriture/pommes.jpg HTTP/1.1
    , l'affichage de la requête par mod_status se présentera comme suit :

    La directive ServerAdmin permet de définir
    l'adresse de contact que le serveur va inclure dans tout message
    d'erreur qu'il envoie au client. Si le programme httpd
    ne reconnait pas l'argument fourni comme une URL, il suppose que
    c'est une adresse électronique, et lui ajoute le préfixe
    mailto: dans les cibles des hyperliens. Il est
    cependant recommandé d'utiliser exclusivement une adresse
    électronique, car de nombreux scripts CGI considèrent ceci comme
    implicite. Si vous utilisez une URL, elle doit pointer vers un autre
    serveur que vous contrôlez. Dans le cas contraire, les utilisateurs
    seraient dans l'impossibilité de vous contacter en cas de problème.
    

    
    Il peut s'avérer utile de définir une adresse dédiée à
    l'administration du serveur, par exemple :
    

    
    ServerAdmin www-admin@foo.example.com
    

    
    car les utilisateurs ne mentionnent pas systématiquement le
    serveur dont ils parlent !

    Contexte:serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La directive ServerAlias permet de définir
    les noms alternatifs d'un serveur utilisables pour atteindre des serveurs virtuels à base de
    nom. La directive ServerAlias peut
    contenir des caractères génériques, si nécessaire.
    

    
    <VirtualHost *:80>
  ServerName server.example.com
  ServerAlias server server2.example.com server2
  ServerAlias *.example.com
  UseCanonicalName Off
  # ...
</VirtualHost>
    

    
    La recherche du serveur virtuel à base de nom correspondant au
    plus près à la requête s'effectue selon l'ordre d'apparition des
    directives <virtualhost> dans le fichier de
    configuration. Le premier serveur virtuel dont le ServerName ou le ServerAlias correspond est choisi, sans
    priorité particulière si le nom contient des caractères génériques
    (que ce soit pour ServerName ou ServerAlias).
    

    
    Tous les noms spécifiés au sein d'une section <VirtualHost> sont traités comme un
    ServerAlias (sans caractères génériques).

    Directive ServerName
    

    

    Description:Nom d'hôte et port que le serveur utilise pour
s'authentifier lui-même
    

    Syntaxe:ServerName
[protocole://]nom-de-domaine|adresse-ip[:port]
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La directive ServerName permet de définir
    les protocole, nom d'hôte et port d'une requête que le serveur
    utilise pour s'authentifier lui-même.
    

    
    La directive ServerName permet (éventuellement en
    conjonction avec la directive ServerAlias) d'identifier de manière unique un
    serveur virtuel, lorsqu'elle est utilisée dans un contexte de serveurs virtuels à base de noms.
    

    
    Cette directive est aussi utilisée lors de la création d'URLs de
    redirection relatives quand la directive UseCanonicalName est définie à une valeur autre
    que la valeur par défaut.
    
    
    
    Par exemple, si le nom de la
    machine hébergeant le serveur web est
    simple.example.com, la machine possède l'alias
    DNS www.example.com, et si vous voulez que le serveur
    web s'identifie avec cet alias, vous devez utilisez la définition
    suivante :
    

    
    ServerName www.example.com
    


    
    La directive ServerName peut apparaître à
    toutes les étapes de la définition du serveur. Toute occurrence
    annule cependant la précédente (pour ce serveur).
    

    
    Si la directive ServerName n'est pas
    définie, le serveur tente de déterminer le nom
    d'hôte visible du point de vue du client en demandant tout d'abord au
    système d'exploitation le nom d'hôte système, et en cas d'échec, en effectuant
    une recherche DNS inverse sur une adresse IP présente sur le système.
    
    
    
    Si la directive
    ServerName ne précise pas de port, le serveur
    utilisera celui de la requête entrante. Il est recommandé de
    spécifier un nom d'hôte et un port spécifiques à l'aide de la
    directive ServerName pour une fiabilité
    optimale et à titre préventif.
    

    
    Si vous définissez des serveurs virtuels à base de
    nom, une directive ServerName située à
    l'intérieur d'une section <VirtualHost> spécifiera quel nom d'hôte
    doit apparaître dans l'en-tête de requête Host: pour
    pouvoir atteindre ce serveur virtuel.
    


    
    Parfois, le serveur s'exécute en amont d'un dispositif qui
    implémente SSL, comme un mandataire inverse, un répartiteur de
    charge ou un boîtier dédié SSL. Dans ce cas, spécifiez le protocole
    https:// et le port auquel les clients se connectent
    dans la directive ServerName, afin de
    s'assurer que le serveur génère correctement ses URLs
    d'auto-identification.
    
    

    
    Voir la description des directives UseCanonicalName et UseCanonicalPhysicalPort pour les
    définitions qui permettent de déterminer si les URLs
    auto-identifiantes (par exemple via le module
    mod_dir) vont faire référence au port spécifié, ou
    au port indiqué dans la requête du client.
    
    

    
    
    
    Si la valeur de la directive ServerName ne
    peut pas être résolue en adresse IP, le démarrage du serveur
    provoquera un avertissement. httpd va alors utiliser le
    résultat de la commande système hostname pour
    déterminer le nom du serveur, ce qui ne correspondra pratiquement
    jamais au nom de serveur que vous souhaitez réellement.

    par le serveur (messages d'erreur, listings de répertoires ftp de
    mod_proxy, sorties de mod_info,
    etc...). Dans le cas d'une chaîne de mandataires, l'utilisateur n'a
    souvent aucun moyen de déterminer lequel des mandataires chaînés a
    généré un message d'erreur, et c'est une des raisons pour lesquelles
    on peut être amené à ajouter un tel pied de page.
    

    
    La valeur par défaut Off supprime la ligne de pied
    de page. la valeur On
    ajoute simplement une ligne contenant le numéro de version du
    serveur ainsi que le nom du serveur virtuel issu de la directive
    ServerName, alors que la valeur
    EMail ajoute en plus une référence "mailto:" à

    traitement de tous les fichiers spécifiés par le gestionnaire défini par l'argument
    nom gestionnaire. Par exemple, dans le cas d'un

    extensions, vous pouvez ajouter la ligne suivante dans un fichier
    .htaccess de ce répertoire :
    

    
    SetHandler imap-file
    


    
    Autre exemple : si vous voulez que le serveur affiche un
    compte-rendu d'état chaque fois qu'une URL du type http://nom
    serveur/status est appelée, vous pouvez ajouter ceci dans
    httpd.conf :
    

    
    <Location "/status">
  SetHandler server-status

    Vous pouvez aussi utiliser cette directive pour associer un

    Pour référencer des variables spécifiques à une requête, y compris les

    Vous pouvez écraser la définition antérieure d'une directive
    SetHandler en utilisant la valeur
    None.
    

    
    Note
    
    
    Comme SetHandler l'emporte sur la
    définition des gestionnaires par défaut, le comportement habituel
    consistant à traiter les URLs se terminant par un slash (/) comme
    des répertoires ou des fichiers index est désactivé.

dernière.
             
    

    Syntaxe:StrictHostCheck ON|OFF
    

    Défaut:StrictHostCheck OFF
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    Compatibilité:Disponible à partir de la version 2.4.49 du serveur HTTP Apache.
    

    
    
    Par défaut, le serveur répond aux requêtes quel que soit le nom d'hôte
    qu'elles contiennent, y compris un nom d'hôte non prévu dans la
    configuration. Bien que cela soit pratique, il peut s'avérer souhaitable de
    restreindre les noms d'hôte qu'une application sous-jacente devra prendre en
    compte car elle va souvent générer des réponses en se référençant elle-même.
    

    
    Si la directive StrictHostCheck est définie à
    ON, le serveur générera une erreur HTTP 400 si le nom d'hôte que
    contient la requête n'a pas été explicitement spécifié par une directive
    ServerName ou ServerAlias au niveau du serveur virtuel qui
    correspond le mieux aux caractéristiques de la connexion entrante.
    

   
    Cette directive permet aussi de rechercher une correspondance entre le nom
   d'hôte de la requête et les noms d'hôte spécifiés au sein de la balise
   ouvrante VirtualHost. Il s'agit
   cependant d'un mécanisme de configuration relativement obscur qui agit comme
   une directive ServerAlias
   supplémentaire.
    

   
    Cette directive n'a aucun effet dans les serveurs virtuels qui ne sont pas
   des serveurs par défaut. La valeur héritée de la configuration globale du
   serveur ou le serveur virtuel par défaut pour l'adresse IP/port de la
   connexion sous-jacente déterminent la valeur effective.

    Directive TimeOut
    

    

    Description:Temps pendant lequel le serveur va attendre certains
évènements avant de considérer qu'une requête a échoué
    

    Syntaxe:TimeOut secondes
    

    Défaut:TimeOut 60
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    La directive TimeOut permet de définir le
    temps maximum pendant lequel Apache httpd va attendre des entrées/sorties
    selon les circonstances :
    

    
      
      
    • Lors de la lecture de données en provenance du client, le
      temps maximum jusqu'à l'arrivée d'un paquet TCP si le tampon est
      vide.
      
      
      Pour les données initiales d'une nouvelle connexion, et tant qu'une
      directive AcceptFilter n'aura pas
      transmis cette nouvelle connexion au serveur, cette directive n'aura aucun
      effet.
      
      
      • 

      
    • Lors de l'écriture de données destinées au client, le temps
      maximum jusqu'à l'arrivée de l'accusé-réception d'un paquet si le
      tampon d'envoi est plein.
      • 

      
    • Avec mod_cgi et mod_cgid, le temps
      d'attente maximum pour un bloc individuel en sortie d'un script CGI.
      • 

      
    • Avec mod_ext_filter, le temps d'attente
      maximum des sorties d'un processus de filtrage.
      • 

      
    • Avec mod_proxy, la valeur du délai par défaut
      si ProxyTimeout n'est
      pas défini.

    Directive TraceEnable
    

    

    Description:Détermine le comportement des requêtes
TRACE
    

    Syntaxe:TraceEnable [on|off|extended]
    

    Défaut:TraceEnable on
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Cette directive l'emporte sur le comportement de
    TRACE pour le noyau du serveur et
    mod_proxy. La définition par défaut
    TraceEnable on permet des requêtes TRACE
    selon la RFC 2616, qui interdit d'ajouter tout corps à la requête.
    La définition TraceEnable off indique au noyau du
    serveur et à mod_proxy de retourner un code
    d'erreur 405 (Méthode non autorisée) au client.
    

    
    En fait, et à des fins de test et de diagnostic seulement, on
    peut autoriser l'ajout d'un corps de requête à l'aide de la
    définition non standard TraceEnable extended. Le noyau
    du serveur (dans le cas d'un serveur d'origine) va limiter la taille
    du corps de requête à 64Kb (plus 8Kb pour les en-têtes de
    fractionnement si Transfer-Encoding: chunked est
    utilisé). Le noyau du serveur va reproduire l'ensemble des en-têtes,
    y compris les en-têtes de fractionnement avec le corps de la
    réponse. Dans le cas d'un serveur mandataire, la taille du corps de
    requête n'est pas limitée à 64Kb.
    

    
    Note
    
    
    Bien que certains prétendent le contraire, activer la méthode
    TRACE ne constitue pas un problème de sécurité dans Apache
    httpd. La méthode TRACE est définie par la spécification
    HTTP/1.1 et les différentes implémentations sont censées la supporter.

    Annule l'effet d'une directive Define ou d'un argument -D de
    httpd en invalidant l'existence de la variable
    correspondante.
    
    
    On peut utiliser cette directive pour inverser l'effet d'une
    section <IfDefine>
    sans avoir à modifier les arguments -D dans les scripts
    de démarrage.
    
    
    
    Afin d'éviter tout risque de collision avec la syntaxe de la directive
    RewriteMap, les noms de
    variables ne doivent pas contenir de caractère ":".
    

    
    Piège de la portée de cette directive
    
      
    Si cette directive est définie au sein d'un bloc VirtualHost, les
      changements qu'elle induit sont visibles de toute directive
      ultérieure, au delà de tout bloc VirtualHost.

    Directive UseCanonicalName
    

    

    Description:Définit la manière dont le serveur détermine son propre nom
et son port
    

    Syntaxe:UseCanonicalName On|Off|DNS
    

    Défaut:UseCanonicalName Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Dans de nombreuses situations, Apache httpd doit construire une URL
    auto-identifiante -- c'est à dire une URL qui fait
    référence au serveur lui-même. Avec UseCanonicalName
    On, Apache httpd va utiliser le nom d'hôte et le port spécifiés par
    la directive ServerName pour
    construire le nom canonique du serveur. Ce nom est utilisé dans
    toutes les URLs auto-identifiantes, et affecté aux variables
    SERVER_NAME et SERVER_PORT dans les
    programmes CGI.
    

    
    Avec UseCanonicalName Off, Apache httpd va construire ses
    URLs auto-identifiantes à l'aide du nom d'hôte et du port fournis
    par le client, si ce dernier en a fourni un (dans la négative,
    Apache utilisera le nom canonique, de la même manière que
    ci-dessus). Ces valeurs sont les mêmes que celles qui sont utilisées
    pour implémenter les serveurs virtuels à base de
    nom, et sont disponibles avec les mêmes clients. De même, les
    variables CGI SERVER_NAME et SERVER_PORT
    seront affectées des valeurs fournies par le client.
    

    
    Cette directive peut s'avérer utile, par exemple, sur un serveur
    intranet auquel les utilisateurs se connectent en utilisant des noms
    courts tels que www. Si les utilisateurs tapent un nom
    court suivi d'une URL qui fait référence à un répertoire, comme
    http://www/splat, sans le slash terminal, vous
    remarquerez qu'Apache httpd va les rediriger vers
    http://www.example.com/splat/. Si vous avez activé
    l'authentification, ceci va obliger l'utilisateur à s'authentifier
    deux fois (une première fois pour www et une seconde
    fois pour www.example.com -- voir la
    foire aux questions sur ce sujet pour plus d'informations).
    Par contre, si UseCanonicalName est définie à
    Off, Apache httpd redirigera l'utilisateur vers
    http://www/splat/.
    

    
    Pour l'hébergement virtuel en masse à base d'adresse IP, on
    utilise une troisième option, UseCanonicalName
    DNS, pour supporter les clients anciens qui ne
    fournissent pas d'en-tête Host:. Apache httpd effectue alors
    une recherche DNS inverse sur l'adresse IP du serveur auquel le
    client s'est connecté afin de construire ses URLs
    auto-identifiantes.
    

    
    Avertissement
    
    
    Les programmes CGI risquent d'être perturbés par cette option
    s'ils tiennent compte de la variable SERVER_NAME. Le
    client est pratiquement libre de fournir la valeur qu'il veut comme
    nom d'hôte. Mais si le programme CGI n'utilise
    SERVER_NAME que pour construire des URLs
    auto-identifiantes, il ne devrait pas y avoir de problème.

    Directive UseCanonicalPhysicalPort
    

    

    Description:Définit la manière dont le serveur
détermine son propre port
    

    Syntaxe:UseCanonicalPhysicalPort On|Off
    

    Défaut:UseCanonicalPhysicalPort Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Dans de nombreuses situations, Apache httpd doit construire une URL
    auto-identifiante -- c'est à dire une URL qui fait
    référence au serveur lui-même. Avec UseCanonicalPhysicalPort
    On, Apache httpd va fournir le numéro de port physique réel utilisé
    par la requête en tant que port potentiel, pour construire le port
    canonique afin que le serveur puisse alimenter la directive
    UseCanonicalName. Avec
    UseCanonicalPhysicalPort Off, Apache httpd n'utilisera pas le
    numéro de port physique réel, mais au contraire se référera aux
    informations de configuration pour construire un numéro de port
    valide.
    

    
    Note
    
    
    L'ordre dans lequel s'effectue la recherche quand on utilise le
    port physique est le suivant :
    
     
    
     
    UseCanonicalName On
    
     
    
     
      
      
    1. Port indiqué dans Servername
      2. 
      
    2. Port physique
      3. 
      
    3. Port par défaut
      4. 
     
    
     
    
     
    UseCanonicalName Off | DNS
    
     
    
     
      
      
    1. Port spécifié dans l'en-tête Host:
      2. 
      
    2. Port physique
      3. 
      
    3. Port spécifié par Servername
      4. 
      
    4. Port par défaut
      5. 
     
    
     
    
     
    

    
    Avec UseCanonicalPhysicalPort Off, on reprend
    l'ordre ci-dessus en supprimant "Port physique".

    Directive <VirtualHost>
    

    

    Description:Contient des directives qui ne s'appliquent qu'à un nom
d'hôte spécifique ou à une adresse IP
    

    Syntaxe:<VirtualHost
    adresse IP[:port] [adresse
    IP[:port]] ...> ...
    </VirtualHost>
    

    Contexte:configuration globale
    

    Statut:Noyau httpd
    

    Module:core
    

    
    
    Les balises <VirtualHost> et
    </VirtualHost> permettent de rassembler un groupe
    de directives qui ne s'appliquent qu'à un serveur virtuel
    particulier. Toute directive autorisée dans un contexte de serveur
    virtuel peut être utilisée. Lorsque le serveur reçoit un requête
    pour un document hébergé par un serveur virtuel particulier, il
    applique les directives de configuration rassemblées dans la section
    <VirtualHost>. adresse
    IP peut être une des entités suivantes, éventuellement suivies
    d'un caractère ':' et d'un numéro de port (ou *) :
    

    
      
      
    • L'adresse IP du serveur virtuel ;
      • 

      
    • Un nom de domaine entièrement qualifié correspondant à
      l'adresse IP du serveur virtuel (non recommandé) ;
      • 

      
    • Le caractère *, qui agit comme un
      caractère générique, et correspond à toute adresse IP.
      • 

      
    • La chaîne _default_, dont la signification est
      identique à celle du caractère *
      • 

    
    

    
    <VirtualHost 10.1.2.3:80>
  ServerAdmin webmaster@host.example.com
  DocumentRoot "/www/docs/host.example.com"
  ServerName host.example.com
  ErrorLog "logs/host.example.com-error_log"
  TransferLog "logs/host.example.com-access_log"
</VirtualHost>
    



    
    Les adresses IPv6 doivent être entourées de crochets car dans le
    cas contraire, un éventuel port optionnel ne pourrait pas être
    déterminé. Voici un exemple de serveur virtuel avec adresse IPv6
    :
    

    
    <VirtualHost [2001:db8::a00:20ff:fea7:ccea]:80>
  ServerAdmin webmaster@host.example.com
  DocumentRoot "/www/docs/host.example.com"
  ServerName host.example.com
  ErrorLog "logs/host.example.com-error_log"
  TransferLog "logs/host.example.com-access_log"
</VirtualHost>
    


    
    Chaque serveur virtuel doit correspondre à une adresse IP, un
    port ou un nom d'hôte spécifique ; dans le premier cas, le serveur
    doit être configuré pour recevoir les paquets IP de plusieurs
    adresses (si le serveur n'a qu'une interface réseau, on peut
    utiliser à cet effet la commande ifconfig alias -- si
    votre système d'exploitation le permet).
    

    
    Note
    
    
    L'utilisation de la directive <VirtualHost> n'affecte en rien les
    adresses IP sur lesquelles Apache httpd est en écoute. Vous devez vous
    assurer que les adresses des serveurs virtuels sont bien incluses
    dans la liste des adresses précisées par la directive Listen.
    
    
    
    
    
    Tout bloc <VirtualHost> doit comporter une directive
    ServerName. Dans le cas
    contraire, le serveur virtuel héritera de la valeur de la directive
    ServerName issue de la
    configuration du serveur principal.
    

    
    A l'arrivée d'une requête, le serveur tente de la
    faire prendre en compte par la section <VirtualHost> qui correspond le mieux en ne
    se basant que sur la paire adresse IP/port. Les chaînes sans
    caractères génériques l'emportent sur celles qui en contiennent. Si
    aucune correspondance du point de vue de l'adresse IP/port n'est
    trouvée, c'est la configuration du serveur "principal" qui sera
    utilisée.
    
    
    
    Si plusieurs serveurs virtuels correspondent du point de vue de
    l'adresse IP/port, le serveur sélectionne celui qui correspond le
    mieux du point de vue du nom d'hôte de la requête. Si aucune
    correspondance du point de vue du nom d'hôte n'est trouvée, c'est le
    premier serveur virtuel dont l'adresse IP/port correspond qui sera
    utilisé. Par voie de conséquence, le premier serveur virtuel
    comportant une certaine paire adresse IP/port est le serveur virtuel
    par défaut pour cette paire adresse IP/port.
    

    
    Sécurité
    
    
    Voir le document sur les conseils à propos de sécurité
    pour une description détaillée des raisons pour lesquelles la
    sécurité de votre serveur pourrait être compromise, si le répertoire
    contenant les fichiers journaux est inscriptible par tout autre
    utilisateur que celui qui démarre le serveur.

    Description:Authentification utilisateur utilisant des fichiers
DBM
    

    Statut:Extension
    

    Identificateur de Module:authn_dbm_module
    

    Fichier Source:mod_authn_dbm.c
    

    Compatibilité:Disponible depuis les versions 2.1 et supérieures
d'Apache
    

    Sommaire
    

    
    Ce module permet aux frontaux comme
    mod_auth_digest et mod_auth_basic
    d'authentifier les utilisateurs en les recherchant dans des fichiers
    de mots de passe dbm. mod_authn_file
    fournit une fonctionnalité similaire.
    

    
    Lorsqu'on utilise mod_auth_basic ou
    mod_auth_digest, ce module est invoqué en affectant
    la valeur dbm à la directive AuthBasicProvider ou AuthDigestProvider.

    Statut:Extension
    

    Module:mod_authn_dbm
    

    
    
    Cette directive permet de définir le type de fichier de base de
    données utilisé pour stocker les mots de passe. Le type de base de
    données par défaut est défini à la compilation. La liste des autres
    types de bases de données disponibles dépend aussi de la configuration de la
    compilation.
    

    
    Par exemple, pour activer le support de Berkeley DB (correspondant au
    type db), il faut ajouter l'option
    --with-berkeley-db à la ligne de commande configure de httpd
    pour générer le DSO approprié.
    

    
    Il est impératif que le programme que vous utilisez pour créer
    vos fichiers de mots de passe soit configuré pour utiliser le même
    type de base de données.
    


    

    top
    

    Directive AuthDBMUserFile
    

    

    Description:Définit le nom d'un fichier de base de données pour
l'authentification contenant la liste
des utilisateurs et de leurs mots de passe
    

    Syntaxe:AuthDBMUserFile chemin-fichier
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_authn_dbm
    

    
    
    La directive AuthDBMUserFile permet de
    définir le nom d'un fichier de base de données pour
    l'authentification contenant la liste des utilisateurs et de leurs
    mots de passe. chemin-fichier doit être un chemin absolu
    vers le fichier de base de données.
    

    
    La clé du fichier de base de données est le nom de l'utilisateur.
    La valeur associée est le mot de passe chiffré, éventuellement suivi
    par un ':' et des données arbitraires. Ce ':' ainsi que les données
    arbitraires qui suivent seront ignorées par le serveur.
    

    
    Sécurité :
    
      
    Faites en sorte que le fichier spécifié par la directive
      AuthDBMUserFile soit stocké en dehors de
      l'arborescence des documents du serveur web ; en particulier, ne
      l'enregistrez pas dans le répertoire qu'il protège, faute
      de quoi, les clients auraient la possibilité de
      télécharger le fichier des mots de passe.
    
    
    

    
    Le format de mot de passe chiffré dépend du frontal
    d'authentification utilisé (par exemple
    mod_auth_basic ou
    mod_auth_digest). Voir la documentation sur les Formats de mots de
    passe pour plus de détails.
    

    
    Note importante concernant la compatibilité : l'implémentation de
    dbmopen dans les modules d'Apache lit la longueur de la
    chaîne correspondant aux données chiffrées dans la structure des
    données DBM, plutôt que de calculer cette longueur en se basant sur
    le caractère nul final. Certaines applications par contre, comme le
    serveur web Netscape, calculent cette longueur en se basant sur
    le caractère nul final ; par conséquent, si vous rencontrez des
    difficultés en échangeant des fichiers DBM entre plusieurs
    applications, le problème peut éventuellement s'expliquer par cette
    différence d'implémentation.
    

    
    Un script perl nommé dbmmanage est fourni avec
    Apache. On peut utiliser ce programme pour créer et mettre à jour
    les fichiers de mots de passe au format DBM que ce module
    utilise. Il existe également un autre outil pour gérer les fichiers DBM,
    inclus dans le programme htdbm.

    In an EBCDIC environment, Apache always translates HTTP protocol
    content (e.g. response headers) from the code page of the Apache
    process locale to ISO-8859-1, but not the body of responses.  In
    any environment, mod_charset_lite can be used to
    specify that response bodies should be translated.  For example,
    if files are stored in EBCDIC, then
    mod_charset_lite can translate them to
    ISO-8859-1 before sending them to the client.
    

    
    This module provides a small subset of configuration
    mechanisms implemented by Russian Apache and its associated
    mod_charset.

    Common Problems
    

    
    Invalid character set names
    

      
    The character set name parameters of CharsetSourceEnc and
      CharsetDefault
      must be acceptable to the translation mechanism used by
      APR on the system where
      mod_charset_lite is deployed.  These character
      set names are not standardized and are usually not the same as
      the corresponding values used in http headers.  Currently, APR
      can only use iconv(3), so you can easily test your character set
      names using the iconv(1) program, as follows:
    

      
    
        iconv -f charsetsourceenc-value -t charsetdefault-value
      
    
    

    
    Mismatch between character set of content and translation
    rules
    

      
    If the translation rules don't make sense for the content,
      translation can fail in various ways, including:
    

      
      
      
    • The translation mechanism may return a bad return code,
      and the connection will be aborted.
      • 

      
    • The translation mechanism may silently place special
      characters (e.g., question marks) in the output buffer when
      it cannot translate the input buffer.
      •

    CharsetDefault Directive
    

    

    Description:Charset to translate into
    

    Syntax:CharsetDefault charset
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_charset_lite
    

    
    
    The CharsetDefault directive specifies the
    charset that content in the associated container should be
    translated to.
    

    
    The value of the charset argument must be accepted
    as a valid character set name by the character set support in
    APR. Generally, this means that it must be
    supported by iconv.
    

    
    Example
    <Directory "/export/home/trawick/apacheinst/htdocs/convert">
    CharsetSourceEnc  UTF-16BE
    CharsetDefault    ISO-8859-1
</Directory>
    

    

     
    
     Specifying the same charset for both CharsetSourceEnc
     and CharsetDefault disables translation. The charset
     need not match the charset of the response, but it must be a valid charset on the system.

    CharsetOptions Directive
    

    

    Description:Configures charset translation behavior
    

    Syntax:CharsetOptions option [option] ...
    

    Default:CharsetOptions ImplicitAdd
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_charset_lite
    

    
    
    The CharsetOptions directive configures certain
    behaviors of mod_charset_lite. Option can
    be one of
    

    
    
      
    ImplicitAdd | NoImplicitAdd
    

      
    The ImplicitAdd keyword specifies that
      mod_charset_lite should implicitly insert its
      filter when the configuration specifies that the character
      set of content should be translated. If the filter chain is
      explicitly configured using the AddOutputFilter directive, NoImplicitAdd
      should be specified so that mod_charset_lite
      doesn't add its filter.
    

      
    TranslateAllMimeTypes | NoTranslateAllMimeTypes
    
      
    Normally, mod_charset_lite will only perform
      translation on a small subset of possible mimetypes.  When the
      TranslateAllMimeTypes keyword is specified for a given
      configuration section, translation is performed without regard for
      mimetype.

    CharsetSourceEnc Directive
    

    

    Description:Source charset of files
    

    Syntax:CharsetSourceEnc charset
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_charset_lite
    

    
    
    The CharsetSourceEnc directive specifies the
    source charset of files in the associated container.
    

    
    The value of the charset argument must be accepted
    as a valid character set name by the character set support in
    APR. Generally, this means that it must be
    supported by iconv.
    

    
    Example
    <Directory "/export/home/trawick/apacheinst/htdocs/convert">
    CharsetSourceEnc  UTF-16BE
    CharsetDefault    ISO-8859-1
</Directory>
    

    

    
    The character set names in this example work with the iconv
    translation support in Solaris 8.
    

     
    
     Specifying the same charset for both CharsetSourceEnc
     and CharsetDefault disables translation. The charset
     need not match the charset of the response, but it must be a valid charset on the system.

    Açıklama:Modüllerin ve çalıştırılabilir kodun sunucunun başlatılması veya
yeniden başlatılması sırasında yüklenmesini sağlar.
    

    Durum:Eklenti
    

    Modül Betimleyici:so_module
    

    Kaynak Dosyası:mod_so.c
    

    Uyumluluk:Windows için bu bir temel modüldür (sunucu bunu daima içerir).
    

    Özet
    


    
    Seçilen işletim sistemleri üzerinde bu modül Apache HTTP Sunucusunun
      yeniden derlenmesini gerektirmeden modüllerin Devingen Paylaşımlı Nesne (DSO) mekanizması üzerinden
      kullanılabilmesini sağlar.
    

    
    Unix’te yüklenen kod genellikle paylaşımlı nesne dosyalarından
      (.so uzantılı dosyalar), Windows’ta ise ya .so
      ya da .dll uzantılı dosyalardan gelir.
    

    
    Uyarı
    
    
    Apache HTTP Sunucusunun ana sürümlerinden biri (1.3, 2.0, 2.2, 2.4 gibi)
      için derlenmiş modüller genelde bir diğerinde çalışmaz. Genellikle
      aralarında API değişikliği sözkonusu olduğundan çalışması için modüllerde
      yeni sürüme göre değişiklik yapılması gerekir.

    Yüklenebilir Modüllerin Windows için Oluşturulması
    
    

    
    Bilginize
    
    
    Windows üzeinde yüklenebilir dosyalar genelde .dll sonekini
      alırlar. Apache httpd modülleri ise diğer platformlardaki gibi
      mod_filanca.so biçeminde isimlendirilmektedir. Bununla
      birlikte, üçüncü parti modüllerden bazılarının (PHP gibi) hala
      .dll sonekini kullandığı görülmektedir.
    

    
    mod_so modülü  ApacheModuleFoo.dll biçeminde
      isimlendirilmiş modülleri hala yüklemekteyse de yeni adlandırma uzlaşımı
      tercih edilmelidir. Yüklenebilir modülleri 2.0’a dönüştürüyorsanız,
      lütfen isimlerini de 2.0 uzlaşımına uygun hale getiriniz.
    

    
    Apache httpd modül programlama arayüzü Unix ve Windows sürümleri
      arasında değişiklik göstermez. Unix için kullanılan çoğu modül hiç
      değişiklik yapmadan ya da çok küçük bir değişiklikle Windows’ta da
      çalışmaktadır. Çalışmayanlar Unix platformunun sahip olduğu ancak Windows
      platformunun sahip olmadığı nitelikleri kullanan modüllerdir.
    

    
    Bir modül Windows’ta çalıştığı zaman, sunucuya iki şekilde
      yüklenebilir. Unix’te olduğu gibi, doğrudan sunucunun içinde
      derlenebilir. Windows için hazırlanan Apache httpd paketi, Unix için
      geçerli olan  Configure betiğini içermediğinden modülün
      kaynak dosyası ApacheCore proje dosyasına, sembolleri de
      os\win32\modules.c dosyasına eklenmelidir.
    

    
    İkinci yol ise modülü bir paylaşımlı kütüphane olarak çalışma anında
      LoadModule yönergesi ile yüklemek
      için bir DLL olarak derlemektir. Bu DLL modüller dağıtılabilir ve
      sunucuyu yeniden derlemek gerekmeksizin her Windows için Apache httpd
      kurulumunda çalışabilir.
    

    
    Bir modül DLL’i oluşturmak için modülün kaynak dosyasında küçük bir
      değişiklik yapmak gerekir: Modül kaydının daha sonra oluşturulacak olan
      DLL’den ihraç edilebilmesi gerekir (aşağıya bakınız). Bunu yapmak için
      modülün modül kaydı tanımına (Apache httpd başlık dosyalarında
      tanımlanmış olan) AP_MODULE_DECLARE_DATA eklenmelidir.
      Örneğin, modülünüz
    

    
    
        module foo_module;
    
    

    
    diye bir satır içeriyorsa bunu,
    

    
    
        module AP_MODULE_DECLARE_DATA foo_module;
    
    

    
    olarak değiştirmelisiniz. Bunun yalnız Windows üzerinde etkili olduğunu
      ve Unix için modül kodunda bir değişiklik gerekmediğini unutmayınız.
      Ayrıca, .DEF dosyaları hakkında bilgi sahibi iseniz modül
      kodunda değişiklik yapmak yerine modül kaydını bu yöntemle de ihraç
      edebilirsiniz.
    

    
    Artık modülü içeren bir DLL oluşturmaya hazırsınız. Bunu, libhttpd.dll
      paylaşımlı kütüphanesi derlenirken oluşturulan libhttpd.lib ihraç
      kütüphanesi ile ilintilemeniz gerekecektir. Ayrıca, Apache httpd başlık
      dosyalarının doğru konumlandığından emin olmak için derleyici
      seçeneklerinde değişiklik yapmanız gerekebilir. Bu kütüphaneyi
      sunucunuzun kök dizini altındaki modules dizininde
      bulabilirsiniz. En iyisi derleme ortamının doğru yapılandırıldığından
      emin olmak için ya ağaçta mevcut modüllerden birinin .dsp
      dosyasını gaspedersiniz ya da kendi .dsp dosyanızın
      ilintileme seçenekleriyle derleyicininkileri karşılaştırırsınız.
    

    
    Artık modülünüzün DLL sürümünü oluşturmalısınız. DLL’i sunucunuzun kök
      dizininin altında bulunan modules dizinine yerleştirdikten
      sonra LoadModule yönergesi ile sunucunuza
      yükleyebilirsiniz.

    AcceptFilter-Direktive
    

    

    Beschreibung:Konfiguriert Optimierungen für lauschende Sockets bestimmter
Protokolle
    

    Syntax:AcceptFilter Protokoll Filter
    

    Kontext:Serverkonfiguration
    

    Status:Core
    

    Modul:core
    

    Kompatibilität:Verfügbar ab Apache 2.1.5
    

    
    
    Diese Direktive aktiviert betriebssystemspezifische Optimierungen
    für lauschende Sockets anhand des Protokolltyps. Der grundlegende
    Ansatz ist, dass der Kernel das Socket nicht an den Serverprozess
    übergibt, bis entweder Daten verfügbar sind oder eine komplette
    HTTP-Anfrage zwischengespeichert wurde. Derzeit werden
    ausschließlich die Accept-Filter von FreeBSD und das primitivere
    TCP_DEFER_ACCEPT von Linux unterstützt.
    

    
    Die Standardeinstellungen für FreeBSD sind:
    
    
    
        AcceptFilter http httpready
    
        AcceptFilter https dataready
    
    

    
    Der httpready-Accept-Filter puffert komplette
    HTTP-Anfragen auf Kernelebene. Sobald eine Anfrage vollständig
    vorliegt, schickt der Kernel sie an den Server weiter. Bitte schlagen Sie
    in der accf_http(9)-Manpage für weitere Details nach. HTTPS-Anfragen
    sind verschlüsselt. Daher wird dafür nur der accf_data(9)-Filter verwendet.
    

    
    Die Standardeinstellungen für Linux sind:
    
    
    
        AcceptFilter http data
    
        AcceptFilter https data
    
    

    
    TCP_DEFER_ACCEPT unter Linux unterstützt keine
    Zwischenspeicherung von HTTP-Anfragen. Jeder andere Wert als
    none aktiviert TCP_DEFER_ACCEPT auf dem
    Lauschsocket. Mehr Details finden Sie in der tcp(7)-Manpage von Linux.
    

    
    Wenn Sie none als Argument verwenden, werden alle
    Accept-Filter für das Protokoll abgeschaltet. Das ist sinnvoll
    für Protokolle, bei denen der Server zuerst Daten senden muss,
    wie zum Beispiel nntp:
    
    
    AcceptFilter nttp none

    AcceptPathInfo-Direktive
    

    

    Beschreibung:Ressourcen lassen angehängte Pfadangaben zu
    

    Syntax:AcceptPathInfo On|Off|Default
    

    Voreinstellung:AcceptPathInfo Default
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis, .htaccess
    

    AllowOverride:FileInfo
    

    Status:Core
    

    Modul:core
    

    Kompatibilität:Verfügbar ab Apache 2.0.30
    

    
    
    Die Direktive steuert, ob Anfragen akzeptiert oder
    abgewiesen werden, bei denen nach der tatsächlichen
    Datei (oder einer nicht existierenden Datei in einem existierenden
    Verzeichnis) zusätzliche Pfadangaben folgen. Die angehängte
    Pfadangabe kann Skripten in der Umgebungsvariable PATH_INFO
    verfügbar gemacht werden.
    

    
    Nehmen wir beispielsweise an, dass /test/ auf ein
    Verzeichnis zeigt, welches lediglich eine Datei here.html
    enthält. Dann wird bei Anfragen nach
    /test/here.html/more und
    /test/nothere.html/more beides Mal /more
    als PATH_INFO ermittelt.
    

    
    Die drei möglichen Argumente für die Direktive
    AcceptPathInfo sind:
    

    
    
    
    Off
    Eine Anfrage wird nur dann akzeptiert,
    wenn sie exakt auf ein existierendes Verzeichnis (oder eine Datei)
    abgebildet werden kann. Daher würde eine Anfrage mit einer nach dem
    tatsächlichen Dateinamen angehängten Pfadangabe, wie
    /test/here.html/more im obigen Beispiel, den Fehler
    404 NOT FOUND (Anm.d.Ü.: nicht gefunden)
    zurückgeben.
    

    
    On
    
    
    Eine Anfrage wird akzeptiert, wenn eine vorangestellte Pfadangabe
    auf ein existierendes Verzeichnis abgebildet werden kann. Das
    obige Beispiel /test/here.html/more wird akzeptiert,
    wenn /test/here.html auf eine gültige Datei
    zeigt.
    

    
    Default
    
    
    Die Behandlung von Anfragen mit angehängten Pfadangaben
    wird von dem für die Anfrage verantwortlichen Handler bestimmt. Der Core-Handler
    für gewöhnliche Dateien weist PATH_INFO-Zugriffe
    standardmäßig zurück. Handler, die Skripte bedienen,
    wie z.B. cgi-script und
    isapi-handler, sind im Allgemeinen darauf
    voreingestellt, PATH_INFO zu akzeptieren.
    
    
    

    
    Das eigentliche Ziel von AcceptPathInfo ist es, Ihnen
    das Überschreiben der Voreinstellung der Handler bezüglich
    der Akzeptanz oder Ablehnung von PATH_INFO zu erlauben.
    Eine solche Änderung ist zum Beispiel notwendig, wenn Sie einen
    Filter wie INCLUDES verwenden, um Inhalte
    abhängig von PATH_INFO zu generieren. Der
    Core-Handler würde die Anfrage normalerweise abweisen. Verwenden
    Sie die folgende Konfiguration, um dennoch solch ein Skript zu
    ermöglichen.
    

    
    
      <Files "mypaths.shtml">
    
      
        Options +Includes
    
        SetOutputFilter INCLUDES
    
        AcceptPathInfo On
    
          
      </Files>

    Vor der Rücksendung des Dokuments
    /usr/local/web/index.html wird der Server
    /.acl, /usr/.acl,
    /usr/local/.acl und /usr/local/web/.acl
    einlesen, solange diese nicht mit
    

    
    
      <Directory />
    
      
        AllowOverride None

    AddDefaultCharset-Direktive
    

    

    Beschreibung:Standard-Charset-Parameter, der bei Antworten vom Content-Type 
  text/plain oder text/html hinzugefügt wird

    

    Syntax:AddDefaultCharset On|Off|Zeichenkodierung
    

    Voreinstellung:AddDefaultCharset Off
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis, .htaccess
    

    AllowOverride:FileInfo
    

    Status:Core
    

    Modul:core
    

    
  
    Die Direktive gibt einen Standardwert für den Charset-Paramter des
    Medientyps (den Namen einer Zeichencodierung) an, der einer Antwort
    genau dann hinzugefügt wird, wenn der Content-Type der Antwort entweder
    text/plain oder text/html ist. Dies sollte jedes
    mittels META-Element im Datenteil der Antwort angegebene
    Charset überschreiben. Das genaue Verhalten hängt jedoch oft von
    der Client-Konfiguration des Benutzers ab. Die Einstellung
    AddDefaultCharset Off deaktiviert diese Funktionalität.
    AddDefaultCharset On aktiviert die Standard-Zeichenkodierung
    iso-8859-1. Jeder andere Wert wird als die zu verwendende
    Zeichenkodierung aufgefaßt, die eines der bei IANA registrierten
      Charset-Werte zur Verwendung in MIME-Medientypen sein sollte. Zum
    Beispiel:
    

    
    
      AddDefaultCharset utf-8
    
    

    
    AddDefaultCharset sollte nur verwendet werden,
      wenn von allen Textressourcen, für die es gilt, bekannt ist, dass sie
      in dieser Zeichkodierung vorliegen, oder wenn es zu unbequem ist, ihre
      Zeichenkodierung indivuell zu benennen. Ein solches Beispiel ist das
      Hinzufügen des Charset-Parameters zu Ressourcen, die generierte
      Inhalte enthalten. Ein Beispiel sind CGI-Skript-Altlasten, die aufgrund von
      in die Ausgabe integrierten Daten, die durch den Benutzer übermittelt
      wurden, gegen Cross-Site-Scripting-Angriffe verwundbar sind. Eine bessere
      Lösung wäre jedoch, diese Skripte zu korrigieren (oder zu
      löschen), da die Angabe einer Standard-Zeichencodierung keine
      Anwender schützt, die in ihrem Browser die Funktion zur
      automatischen Erkennung der Zeichenkodierung aktiviert haben.

    Status:Core
    

    Modul:core
    

    Kompatibilität:Verfügbar ab Apache 2.0.46
    

    
    
    Die AllowEncodedSlashes-Direktive erlaubt die
    Verwendung von URLs, welche kodierte Pfadtrennzeichen (%2F
    für / und auf entsprechenden Systemen zusätzlich
    %5C für \) enthalten. Normalerweise werden
    derartige URLs mit einem 404-Fehler (Nicht gefunden) abgewiesen.
    

    
    AllowEncodedSlashes On ist
    vor allem in Verbindung mit PATH_INFO hilfreich.
    

    
    Anmerkung
    
      
    Das Erlauben von Schrägstrichen impliziert nicht deren
      Dekodierung. Vorkommen von %2F oder %5C
      (nur auf entsprechenden Systemen) werden unverändert in der
      ansonsten dekodierten URL belassen.

    Kontext:Verzeichnis
    

    Status:Core
    

    Modul:core
    

    
    
    Wenn der Server eine .htaccess-Datei (wie durch
    AccessFileName definiert)
    findet, muss er wissen, welche in der Datei angegebenen Direktiven
    frühere Konfigurationsanweisungen überschreiben
    dürfen.
    

    
    Nur in <Directory>-Abschnitten verfügbar
    
    AllowOverride ist nur in <Directory>-Abschnitten
    gültig, die ohne reguläre Ausdrücke definiert wurden, nicht
    in <Location>-, 
    <DirectoryMatch>- oder
    <Files>-Abschnitten.
    
    

    
    Wenn diese Anweisung auf None gesetzt wird, dann
    werden .htaccess-Dateien komplett
    ignoriert. In diesem Fall wird der Server nicht einmal versuchen,
    die .htaccess-Dateien im Dateisystem zu lesen.
    

    
    Wenn diese Anweisung auf All gesetzt wird, dann
    ist jede Direktive in den .htaccess-Dateien erlaubt,
    die den Kontext
    .htaccess besitzt.
    

    
    Der Direktiven-Typ kann eine der folgenden
    Anweisungsgruppen sein.
    

    
    
      
    AuthConfig
    

      
    
      Erlaubt die Verwendung von Autorisierungs-Anweisungen (AuthDBMGroupFile,
      AuthDBMUserFile,
      AuthGroupFile,
      AuthName,
      AuthType, AuthUserFile, Require usw.).
    

      
    FileInfo
    

      
    
      Erlaubt die Verwendung von Direktiven zur Steuerung der
      Dokumenttypen (DefaultType, ErrorDocument, ForceType, LanguagePriority,
      SetHandler, SetInputFilter, SetOutputFilter, und
      mod_mime-Direktiven Add* und Remove*
      usw.), Metadaten (Header, RequestHeader, SetEnvIf, SetEnvIfNoCase, BrowserMatch, CookieExpires, CookieDomain, CookieStyle, CookieTracking, CookieName),
      mod_rewrite-Direktiven RewriteEngine, RewriteOptions, RewriteBase, RewriteCond, RewriteRule) und
      Action aus
      mod_actions.
      
    

      
    Indexes
    

      
    
      Erlaubt die Verwendung von Direktiven zur Steuerung von
      Verzeichnisindizes (AddDescription,
      AddIcon, AddIconByEncoding,
      AddIconByType,
      DefaultIcon, DirectoryIndex, 
	  FancyIndexing, HeaderName, IndexIgnore, IndexOptions, ReadmeName
      usw.).
    

      
    Limit
    

      
    
      Erlaubt die Verwendung von Direktiven zur Steuerung des
      Zugriffs von Hosts (Allow, Deny und Order).
    

      
    Options[=Option,...]
    

      
    
      Erlaubt die Verwendung von Direktiven zur Steuerung spezieller
      Verzeichniseigenschaften (Options
      und XBitHack). Sie
      können mit einem Gleichheitszeichen gefolgt von einer
      kommaseparierten Liste (ohne Leerzeichen) angeben, welche Optionen mit
      der Options-Direktive gesetzt
      werden dürfen.
    
    
    

    
    Beispiel:
    

    
    
      AllowOverride AuthConfig Indexes
    
    
    
    
    Im obigen Beispiel erzeugen alle Direktiven einen internal server
      error (Anm.d.Ü.: Server-interner Fehler), die weder der
      Gruppe AuthConfig noch der Gruppe Indexes
      angehören.

    Die Direktive aktiviert die Generierung von
    Content-MD5-Headern, wie sie in RFC1864 bzw. RFC2616
    definiert sind.
    

    
    MD5 ist ein Algorithmus zur Berechnung eines "Datenextrakts"
    (zuweilen "Fingerabdruck" genannt) (Anm.d.Ü.: Der "Datenextrakt" wird im
    Englischen als "message digest" oder "fingerprint" bezeichnet.)
    aus beliebig langen Daten. Es gilt als zuverlässig, dass
    Veränderungen an den Daten sich in Veränderungen des
    Extrakts wiederspiegeln.
    

    
    Der Content-MD5-Header bietet eine
    End-to-End-Integritätsprüfung (MIC) (Anm.d.Ü.: MIC steht für
    "message integrity check".) des Daten-Inhalts. Ein Proxy oder
    Client kann diesen Header prüfen, um zufällige Veränderungen
    des Entity-Inhalts bei der Übertragung festzustellen.
    Beispielheader:
    

    
    
      Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
    
    

    
    Beachten Sie bitte, dass dies Performanceprobleme auf Ihrem
    System verursachen kann, da der Extrakt bei jeder Anfrage
    berechnet wird (der Wert wird nicht zwischengespeichert).
    

    
    Content-MD5 wird nur für Dokumente gesendet,
    die von core bedient werden, nicht jedoch bei
    Modulen. SSI-Dokumente, CGI-Skript-Ausgaben und Byte-Range-Antworten
    besitzen diesen Header beispielsweise nicht.

    Status:Core
    

    Modul:core
    

    
    
    Es kann vorkommen, dass der Server ein Dokument ausliefern muss,
    dessen Typ er nicht mit Hilfe seiner MIME-Type-Zuordnungen bestimmen kann.
    

    
    Der Server muss den Client über den Content-Type des
    Dokumentes informieren. Daher verwendet er im Falle eines
    unbekannten Typs die DefaultType-Einstellung.
    Zum Beispiel:
    

    
    
      DefaultType image/gif
    
    

    
    wäre angemessen für ein Verzeichnis, das viele GIF-Bilder
    enthält, deren Dateinamen nicht Endung .gif
    besitzen.
    

    
    Beachten Sie bitte, dass die Direktive anders als ForceType lediglich den Standard-MIME-Type
    bestimmt. Alle anderen MIME-Type-Definitionen, einschließlich
    Dateierweiterungen, die den Medien-Typ anzeigen können,
    überschreiben diese Voreinstellung.

    <Directory>-Direktive
    

    

    Beschreibung:Umschließt eine Gruppe von Direktiven, die nur auf
das genannte Verzeichnis des Dateisystems und Unterverzeichnisse angewendet
werden
    

    Syntax:<Directory Verzeichnispfad>
... </Directory>
    

    Kontext:Serverkonfiguration, Virtual Host
    

    Status:Core
    

    Modul:core
    

    
    
    <Directory> und
    </Directory> werden dazu verwendet, eine Gruppe
    von Direktiven zusammenzufassen, die nur für das genannte
    Verzeichnis und dessen Unterverzeichnisse gelten. Jede Direktive,
    die im Verzeichnis-Kontext erlaubt ist, kann verwendet werden.
    Verzeichnispfad ist entweder der vollständige Pfad zu
    einem Verzeichnis oder eine Zeichenkette mit Platzhaltern wie sie von der
    Unix-Shell zum Abgleich verwendet werden. In einer Zeichenkette
    mit Platzhaltern (Anm.d.Ü.: sogenannte wild-cards) entspricht
    ? einem einzelnen Zeichen und * einer
    Zeichenkette beliebiger Länge. Sie können auch auch
    []-Zeichenbereiche verwenden. Keiner der Platzhalter
    entspricht dem Zeichen "/". Daher passt <Directory
    /*/public_html> nicht auf /home/user/public_html,
    <Directory /home/*/public_html> jedoch tut es.
    Beispiel:
    

    
    
      <Directory /usr/local/httpd/htdocs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
    

    
    
      
    Seien Sie vorsichtig mit den Verzeichnispfad-Argumenten.
      Sie müssen buchstäblich mit dem Dateisystempfad
      übereinstimmen, den der Apache für den Zugriff auf die
      Dateien verwendet. Direktiven, die für ein bestimmtes
      Verzeichnis gelten, gelten nicht für Dateien in dem Verzeichnis,
      auf die über einen anderen Pfad zugegriffen wird, wie z.B.
      über verschiedene symbolische Links.
    
    
    

    
    Erweiterte reguläre Ausdrücke können ebenfalls
    verwendet werden, indem das Zeichen ~ hinzugefügt
    wird. Beispielsweise würde
    

    
    
      <Directory ~ "^/www/.*/[0-9]{3}">
    
    

    
    auf Verzeichnisse in /www/ passen, die aus drei
    Zahlen bestehen.
    

    
    Wenn mehrere <Directory>-Abschnitte
    (ohne reguläre Ausdrücke) auf ein Verzeichnis (oder
    ein ihm übergeordnetes Verzeichnis) passen, welches ein Dokument
    enthält, dann werden die Direktiven der Reihe nach, angefangen
    beim kürzesten passenden Muster, vermischt mit den Direktiven
    aus den .htaccess-Dateien, angewendet.
    Beispiel:
    

    
    
      <Directory />
    
      
        AllowOverride None
    
          
      </Directory>
    
      
    
      <Directory /home/>
    
      
        AllowOverride FileInfo
    
          
      </Directory>
    
    

    
    Beim Zugriff auf das Dokument /home/web/dir/doc.html
    sind die einzelnen Schritte:
    

    
      
      
    • Wende die Direktive AllowOverride None an
      (deaktiviere .htaccess-Dateien).
      • 

      
    • Wende die Direktive AllowOverride FileInfo
      (auf das Verzeichnis /home) an.
      • 

      
    • Wende jede FileInfo-Direktive aus
      /home/.htaccess, /home/web/.htaccess und
      /home/web/dir/.htaccess der Reihe nach an.
      • 
    
    

    
    Reguläre Ausdrücke werden solange nicht berücksichtigt,
    bis alle normalen Abschnitte angewendet wurden. Anschließend
    werden alle regulären Ausdrücke in der Reihenfolge
    geprüft, in der sie in der Konfigurationsdatei auftauchen.
    Beispielsweise wird bei
    

    
    
      <Directory ~ abc$>
    
      
        # ... hier die Direktiven ...
    
          
      </Directory>
    
    

    
    der Abschnitt mit dem regulären Ausdruck nicht
    berücksichtigt, bis alle normalen
    <Directory>-Abschnitte und
    .htaccess-Dateien angewendet wurden. Dann erst wird
    der reguläre Ausdruck mit /home/abc/public_html/abc
    abgeglichen und der entsprechende <Directory>-Abschnitt angewendet.
    

    
    Beachten Sie bitte, dass der vom Apache voreingestellte
    Zugriff für <Directory />
    Allow from All ist. Das bedeutet, dass der Apache
    jede Datei ausliefert, die durch eine URL abgebildet wird. Es wird
    empfohlen, dass Sie dies durch einen Block wie
    

    
    
      <Directory />
    
      
        Order Deny,Allow
    
        Deny from All
    
          
      </Directory>
    
    

    
    ändern und anschließend für
    Verzeichnisse überschreiben, die Sie verfügbar machen
    wollen. Für weitere Einzelheiten lesen Sie bitte
    die Seite zu den Sicherheitshinweisen.
    

    
    Die Verzeichnisabschnitte erscheinen in der Datei
    httpd.conf. <Directory>-Direktiven dürfen nicht
    ineinander verschachtelt werden oder innerhalb von <Limit>- oder <LimitExcept>-Abschnitten auftauchen.

    httpd Dateien ausliefert. Sofern nicht eine Direktive
    wie Alias greift, hängt
    der Server Pfade aus der angeforderten URL an das Wurzelverzeichnis
    an, um den Pfad zum Dokument zu bilden. Beispiel:
    

    
    
      DocumentRoot /usr/web
    
    

    
    Damit bezieht sich ein Zugriff auf
    http://www.my.host.com/index.html auf
    /usr/web/index.html. Wenn das Verzeichnis nicht
    absolut angegeben ist, wird es relativ zu ServerRoot betrachtet.
    

    
    DocumentRoot sollte ohne einen

    Auslieferung einer mittels mod_include serverseitig
    analysierten Datei --, dann verwendet der Apache standardmäßig
    Memory-Mapping für diese Datei, sofern das Betriebssystem es
    unterstützt.
    

    
    Memory-Mapping bedeutet zuweilen eine Performanceverbesserung.
    In einigen Umgebungen ist es jedoch besser, Memory-Mapping zu
    deaktivieren, um Problemen während des Betriebs vorzubeugen:
    

    
      
    
    • Bei einigen Multiprozessorsystemen kann Memory-Mapping die
    Performance von httpd reduzieren.
      • 
    
    • Bei einem per NFS eingebundenen DocumentRoot kann httpd mit
    einem Speicherzugriffsfehler (Anm.d.Ü.: ein so genannter "segmentation
    fault") abstürzen, wenn eine Datei gelöscht oder
    gekürzt wird, während httpd sie im Speicher
    abbildet.
      • 
    
    

    
    Bei Serverkonfigurationen, die für dieses Problem
    anfällig sind, sollten Sie das Memory-Mapping für
    auszuliefernde Dateien deaktivieren, indem Sie schreiben:
    

    
    
      EnableMMAP Off
    
    

    
    Bei per NFS eingebundenen Dateien kann diese Funktion
    explizit für die störenden Dateien deaktiviert werden,
    indem Sie angeben:
    

    
    
      <Directory "/pfad-zu-den-nfs-dateien">
      
        EnableMMAP Off

    EnableSendfile-Direktive
    

    

    Beschreibung:Verwende die sendfile-Unterstützung des Kernels, um
Dateien an den Client auszuliefern
    

    Syntax:EnableSendfile On|Off
    

    Voreinstellung:EnableSendfile On

    AllowOverride:FileInfo
    

    Status:Core
    

    Modul:core
    

    Kompatibilität:Verfügbar ab Apache Version 2.0.44
    

    
    
    Die Direktive steuert, ob httpd die
    sendfile-Unterstützung des Kernels verwenden kann, um
    Dateiinhalte an den Client zu übermitteln. Wenn die Bearbeitung
    einer Anfrage keinen Zugriff auf die Daten in der Datei erfordert --
    zum Beispiel bei der Auslieferung einer statischen Datei -- und das
    Betriebssystem es unterstützt, verwendet der Apache
    standardmäßig sendfile, um den Dateiinhalt zu
    übertragen, ohne die Datei jemals zu lesen.
    

    
    Der sendfile-Mechanismus vermeidet getrennte Lese- und
    Sendeoperationen sowie Puffer-Zuweisungen. Bei einigen Plattformen bzw.
    Dateisystemen deaktivieren Sie diese Funktion jedoch besser, um Probleme
    während des Betriebs zu vermeiden:
    

    
      
    
    • Einige Plattformen besitzen u.U. eine fehlerhafte
    sendfile-Unterstützung, die das Erstellungssystem nicht erkennt,
    insbesondere wenn die Binärdateien auf einem anderen Rechner erstellt
    und auf eine solche Maschine mit fehlerhafter sendfile-Unterstützung
    übertragen wurden.
      • 
    
    • Bei einem über das Netzwerk eingebundenen DocumentRoot (z.B. NFS oder SMB) ist der
    Kernel möglicherweise nicht in der Lage, die Netzwerkdatei
    über seinen eigenen Cache zu bedienen.
      • 
    
    • Unter Linux löst die Verwendung von sendfile
    in Verbindung mit bestimmten Netzwerkkarten und IPv6
    TCP-Checksummenfehler aus.
      • 
    
    • Unter Linux auf Itanium-Systemen kommt sendfile unter Umständen
    nicht mit Dateien größer als 2GB klar.
      • 
    
    

    
    Bei Serverkonfigurationen, die für dieses Problam
    anfällig sind, sollten die diese Funktion deaktivieren, indem
    Sie schreiben:
    

    
    
      EnableSendfile Off
    
    

    
    Bei per NFS oder SMB eingebundenen Dateien kann diese Funktion
    explizit für die störenden Dateien deaktiviert werden, indem
    Sie angeben:
    

    
    
      <Directory "/pfad-zu-den-nfs-dateien">
      
        EnableSendfile Off
      
      </Directory>
    
    
    
    Beachten Sie bitte, dass die verzeichnisbasierte und
       .htaccess-Konfiguration von EnableSendfile
       nicht vom mod_cache_disk-Modul unterstützt wird.
       Nur die globale Konfiguration von EnableSendfile
       wird vom Modul beachtet.

zurückgibt
    

    Syntax:ErrorDocument Fehlercode Dokument
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis, .htaccess
    

    AllowOverride:FileInfo
    

    Status:Core
    

    Modul:core
    

    Kompatibilität:Die Syntax der Anführungszeichen bei Textnachrichten hat
sich im Apache 2.0 geändert
    

    
    
    Im Falle eines Problems oder Fehlers kann der Apache
    konfiguriert werden, eine der vier Aktionen auszuführen:
    

    
      
      
    1. Ausgabe einer einfachen, hartkodierten Fehlermeldung
      2. 

      
    2. Ausgabe einer angepassten Meldung
      3. 

      
    3. Umleitung zu einem lokalen URL-Pfad der das
      Problem bzw. den Fehler behandelt
      4. 

      
    4. Umleitung zu einer externen URL, die das Problem
      bzw. den Fehler behandelt
      5. 
    
    

    
    Die erste Option ist Voreinstellung, während die Optionen
    2 bis 4 über die Direktive ErrorDocument
    eingestellt werden, welcher der HTTP-Statuscode und eine
    URL oder Nachricht folgen. Abhängig vom Problem bzw. Fehler bietet
    der Apache manchmal zusätzliche Informationen an.
    

    
    URLs können bei lokalen Webpfaden mit einem Schrägstrich
    (/) beginnen (relativ zum DocumentRoot-Verzeichnis) oder eine vollständige URL
    bilden, die der Client auflösen kann. Alternativ kann eine
    Nachricht für die Anzeige im Browser angeboten werden. Beispiel:
    

    
    
      ErrorDocument 500 http://foo.example.com/cgi-bin/tester
    
      ErrorDocument 404 /cgi-bin/falsche_urls.pl
    
      ErrorDocument 401 /info_zur_anmeldung.html
    
      ErrorDocument 403 "Der Zugriff ist nicht erlaubt."
    
    

    
    Außerdem kann der spezielle Wert default angegeben
      werden, um die schlichte, hartkodierte Nachricht des Apache zu verwenden.
      Es wird normalerweise nicht benötigt, doch default
      stellt die einfach, im Apache hartkodierte Meldung in Konfigurationen
      wieder her, die ansonsten von einem existierenden (Anm.d.Ü.: zuvor
        konfigurierten) ErrorDocument erben
      würden.
    

    
    
      ErrorDocument 404 /cgi-bin/bad_urls.pl

    
      <Directory /web/docs>
    
      
        ErrorDocument 404 default
    
          
      </Directory>
    
    

    
    Wenn Sie eine ErrorDocument-Anweisung
    angeben, die auf eine entfernte URL weist (d.h. irgendetwas mit der
    Methode http davor), beachten Sie bitte, dass der Apache
    eine Umleitung zum Client sendet, um diesem mitzuteilen, wo das
    Dokument zu finden ist, auch wenn das Dokument letztlich wieder zum
    gleichen Server führt. Das hat mehrere Auswirkungen. Die
    wichtigste ist, dass der Client nicht den Original-Statuscode
    erhält sondern statt dessen einen Umleitungs-Statuscode. Dies
    wiederum kann Web-Robots und andere Clients verwirren, die den
    Statuscode dazu verwenden, herauszufinden ob eine URL gültig ist.
    Wenn Sie eine entfernte URL in einer Anweisung
    ErrorDocument 401 verwenden, wird der Client
    darüber hinaus nicht wissen, dass er den Benutzer zur Eingabe
    eines Passwortes auffordern muss, da er den Statuscode 401 nicht
    erhält. Deshalb müssen Sie sich auf ein lokales
    Dokument beziehen, wenn Sie eine Anweisung ErrorDocument
    401 verwenden.
    

    
    Der Microsoft Internet Explorer (MSIE) ignoriert
    standardmäßig serverseitig generierte Fehlermeldungen, wenn
    sie "zu kurz" sind und ersetzt sie durch eigene "freundliche"
    Fehlermeldungen. Die Größe variiert abhängig von der
    Art des Fehlers, im Allgemeinen zeigt der MSIE jedoch den
    serverseitig generierten Fehler, anstatt ihn zu verstecken, wenn Ihr
    Fehlerdokument größer als 512 Bytes ist. Weitere Informationen
    sind im Artikel  Q294807 in der Microsoft Knowledgebase verfügbar.
    

    
    Obwohl die meisten Fehlermeldungen überschrieben werden
    können, werden unter bestimmten Umständen die internen
    Meldungen ungeachtet der Einstellung der ErrorDocument-Direktive verwendet. Insbesondere bei
    einer fehlerhaften Anfrage werden der normale Bearbeitungsprozess sofort
    beendet und die interne Meldung zurückgegeben. Das ist notwendig, um
    Sicherheitsprobleme zu vermeiden, die auf Grund fehlerhafter Anfragen
    entstehen.
    

    
    In Versionen vor 2.0 wurden Meldungen durch ein einzelnes
    vorangestelltes Anführungszeichen (") erkannt.

    ErrorLog-Direktive
    

    

    Beschreibung:Ablageort, an dem der Server Fehler protokolliert
    

    Syntax: ErrorLog Dateiname|syslog[:facility]
    

    Voreinstellung:ErrorLog logs/error_log (Unix) ErrorLog logs/error.log (Windows and
  OS/2)
    

    Kontext:Serverkonfiguration, Virtual Host
    

    Status:Core
    

    Modul:core
    

    
    
    Die Direktive ErrorLog bestimmt den Namen
    der Datei, in welcher der Server alle auftretenden Fehler protokolliert.
    Wenn Dateiname nicht absolut ist, wird er relativ zu ServerRoot betrachtet.
    

    
    Beispiel
    
    ErrorLog /var/log/httpd/error_log
    
    

    
    Wenn der Dateiname mit einem senkrechten Strich (|,
    engl.: Pipe) beginnt, wird angenommen, dass es sich um einen Befehl
    handelt, der ausgeführt wird, um das Fehlerprotokolls zu
    verarbeiten.
    

    
    Beispiel
    
    ErrorLog "|/usr/local/bin/httpd_errors"
    
    

    
    Die Verwendung von syslog anstelle eines Dateinamens
    aktiviert die Protokollierung mittels syslogd(8), sofern das System
    es unterstützt. Als Voreinstellung wird der syslog-Typ (syslog
    facility) local7 verwendet, Sie können dies jedoch
    auch überschreiben, indem Sie die Syntax
    syslog:facility verwenden, wobei
    facility einer der Namen sein kann, die üblicherweise
    in syslog(1) dokumentiert sind.
    

    
    Beispiel
    
    ErrorLog syslog:user
    
    

    
    SICHERHEITSHINWEIS: Lesen Sie das Dokument Sicherheitshinweise
    zu Einzelheiten darüber, warum Ihre Sicherheit gefährdet
    sein kann, wenn das Verzeichnis, in dem die Log-Dateien gespeichert
    werden, für jemand anderen, als den Benutzer, der den Server
    gestartet hat, beschreibbar ist.
    

    
    Anmerkung
    
      
    Bei der Eingabe eines Dateipfads auf nicht-Unix-Plattformen sollte
      darauf geachtet werden, nur (Vorwärts-)Schrägstriche zu
      verwenden, auch wenn die Plattform rückwärts gerichtete
      Schrägstriche (Backslashes) erlaubt. Im Allgemeinen ist es eine gute
      Idee, innerhalb der Konfigurationsdateien immer
      Vorwärts-Schrägstriche zu verwenden.

    Status:Core
    

    Modul:core
    

    
    
    Wenn dem Dokument eine Datei zugrundeliegt, bestimmt die Direktive
    FileETag die Dateiattribute, die zur Erstellung
    des HTTP-Response-Headers ETag (Entity-Tag) verwendet
    werden. (Der Wert von ETag wird bei der Cache-Verwaltung
    zur Einsparung von Netzwerk-Bandbreite benutzt.) Im Apache 1.3.22 und
    früher wurde der ETag-Wert stets aus
    der I-Node, der Größe und dem Datum der letzten
    Änderung (mtime) der Datei gebildet. Die Direktive
    FileETag erlaubt es Ihnen, zu bestimmen,
    welche dieser Eigenschaften -- falls überhaupt -- verwendet
    werden sollen. Die gültigen Schlüsselworte lauten:
    

    
    
     
    INode
    
     
    Die I-Node-Nummer wird in die Berechnung mit einbezogen
    
     
    MTime
    
     
    Datum und Uhrzeit der letzten Änderung werden mit einbezogen
    
     
    Size
    
     
    Die Anzahl der Bytes in der Datei wird mit einbezogen
    
     
    All
    
     
    Alle verfügbaren Angaben werden verwendet. Die ist
     gleichbedeutend mit:
         
    FileETag INode MTime Size
    
     
    None
    
     
    Es wird keine ETag-Angabe in die Antwort eingefügt,
     wenn dem Dokument eine Datei zugrundeliegt.
    
    
    

    
    Den Schlüsselwörtern INode, MTime
    und Size kann entweder ein + oder ein
    - vorangestellt werden, was die Änderung einer
    Vorgabe erlaubt, die von einem größeren Umfeld
    geerbt wurde. Jedes Schlüselwort ohne ein solches Prefix
    hebt die ererbte Einstellung sofort und vollständig auf.
    

    
    Wenn die Konfiguration für ein Verzeichnis
    FileETag INode MTime Size enthält
    und die eines Unterverzeichnisses FileETag -INode,
    dann ist die Einstellung für das Unterverzeichnis (die an
    jedes Unter-Unterverzeichnis weitervererbt wird, welches dies nicht
    überschreibt) äquivalent mit
    FileETag MTime Size.

    Die Direktive <Files>
    begrenzt die Reichweite der enthaltenen Anweisungen auf Dateinamen.
    Sie ist vergleichbar mit den Direktiven <Directory> und <Location>. Sie muss eine
    passende </Files>-Anweisung besitzen.
    Die innerhalb dieses Abschnittes angegebenen Direktiven werden auf
    jedes Objekt mit einem Basisnamen (letzte Komponente des Dateinamens)
    angewendet, der auf die angegebenen Dateinamen passt. <Files>-Container werden, nachdem die
    <Directory>-Container
    und .htaccess-Dateien gelesen sind, jedoch vor den
    <Location>-Containern,
    in der Reihenfolge ihres Auftretens ausgeführt. Beachten Sie, dass
    <Files>-Anweisungen innerhalb von
    <Directory>-Containern
    auftreten können, um den Teil des Dateisystems einzuschränken,
    den sie betreffen.
    

    
    Das Argument Dateiname kann einen Dateinamen oder eine
    Zeichenkette mit Platzhaltern enthalten, wobei ? auf ein
    einzelnes Zeichen passt und * auf eine beliebige Folge von
    Zeichen. Erweiterte reguläre
    Ausdrücke können ebenfalls verwendet werden, indem
    das Zeichen ~ hinzugefügt wird. Beispielsweise
    würde
    

    
    
      <Files ~ "\.(gif|jpe?g|png)$">
    
    

    
    auf die gebräuchlichsten Grafikformate im Internet passen.
    <FilesMatch> wird
    jedoch bevorzugt.
    

    
    Beachten Sie bitte, dass die <Files>-Container anders als <Directory>- und <Location>-Container innerhalb
    von .htaccess-Dateien verwendet werden können.
    Dies erlaubt den Anwendern auf Dateiebene die Kontrolle über ihre
    eigenen Dateien.

    Diese Direktive aktiviert die DNS-Abfrage (Anm.d.Ü.: ein sogenannter
    DNS-Lookup), so dass Hostnamen protokolliert (und in
    REMOTE_HOST an CGIs/SSIs übergeben) werden könnnen.
    Der Wert Double bezieht sich auf ein
    Double-Reverse-DNS-Lookup. D.h. nachdem ein Reverse-Lookup
    durchgeführt wurde, wird dann auf dem Ergebnis ein
    Forward-Lookup ausgeführt. Wenigstens eine der IP-Adressen
    aus dem Forward-Lookup muss der Originaladresse entsprechen.
    (In der "tcpwrappers"-Terminologie wird dies PARANOID
    genannt.)
    

    
    Unabhängig von der Einstellung wird ein Double-Reverse-Lookup
    durchgeführt, wenn mod_authz_host zur
    Zugriffskontrolle per Hostnamen eingesetzt wird. Dies ist aus
    Sicherheitsgründen notwendig. Beachten Sie, dass das Ergebnis dieses
    Double-Reverse-Lookups nicht generell verfügbar ist, solange Sie
    nicht HostnameLookups Double setzen. Wenn beispielsweise
    nur HostnameLookups On angegeben ist und eine Anfrage
    für ein Objekt erfolgt, welches durch Hostnamen-Beschränkungen
    geschützt ist, dann wird CGIs nur das Ergebnis des
    Singel-Reverse-Lookups in REMOTE_HOST übergeben,
    egal ob das Doble-Reverse-Lookup fehlschlug oder nicht.
    

    
    Die Voreinstellung ist Off, um Netzwerktraffic bei den
    Angeboten einzusparen, die nicht tatsächlich Reverse-Lookups
    benötigen. Es ist auch für die Endanwender besser, da sie nicht
    die zusätzliche Wartezeit ertragen müssen, die ein Lookup mit
    sich bringt. Hoch frequentierte Angebote sollten diese Direktive auf
    Offlassen. Das Hilfsprogramm logresolve, das standardmäßig in das
    Unterverzeichnis bin Ihres Installationsverzeichnisses
    kompiliert wird, kann dazu verwendet werden, um offline Hostnamen von
    protokollierten IP-Adressen nachzuschlagen.

    Beschreibung:Schließt Direktiven ein, die nur ausgeführt werden,
wenn eine Testbedingung beim Start wahr ist
    

    Syntax:<IfDefine [!]Parametername> ...

    Der Container <IfDefine Test>...</IfDefine>
     wird dazu verwendet, Direktiven als bedingt zu kennzeichnen.
    Die Direktiven innerhalb eines <IfDefine>-Abschnittes werden nur ausgeführt,
    wenn Test wahr ist. Ist Test falsch, wird alles
    zwischen der Start- und Endemarkierung ignoriert.
    

    
    In der <IfDefine>-Anweisung kann
    Test eine von zwei Formen annehmen:
    

    
      
      
    • Parametername
      • 

      
    • !Parametername
      • 
    
    

    
    Im ersten Fall werden die Direktiven zwischen der Start- und
    Endemarkierung nur ausgeführt, wenn der Parameter namens
    Parametername definiert ist. Die zweite Form kehrt den
    Test um und führt die Direktiven nur dann aus, wenn
    Parametername nicht definiert ist.
    

    
    Das Argument Parametername ist ein sogenanntes
    "Define", das beim beim Start des Servers in der
    httpd-Befehlszeile durch
    -DParameter angegeben wird.
    

    
    <IfDefine>-Container können
    ineinander verschachtelt werden, um einfache Multi-Parameter-Tests
    zu implementieren. Beispiel:
    

    
    
      httpd -DReverseProxy ...
    
      
    
      # httpd.conf

    Der Container <IfModule
    Test>...</IfModule> wird dazu verwendet,
    Direktiven als abhängig von dem Vorhandensein eines speziellen
    Moduls zu kennzeichnen. Die Direktiven innerhalb eines <IfModule>-Abschnitts werden nur
    ausgeführt, wenn Test wahr ist. Ist Test
    falsch, wird alles zwischen der Start- und Endemarkierung ignoriert.
    

    
    In der <IfModule>-Anweisung
    kann Test eine von zwei Formen annehmen:
    

    
      
      
    • Modul
      • 

      
    • !Modul
      • 
    
    

    
    Im ersten Fall werden die Direktiven zwischen der Start- und
    Endemarkierung nur ausgeführt, das Modul namens
    Modul im Apache enthalten ist -- entweder einkompiliert
    oder mittels LoadModule
    dynamisch geladen. Die zweite Form dreht den Test um und führt die
    Direktiven nur aus, wenn Modul nicht
    enthalten ist.
    

    
    Das Argument Modul kann entweder der Modulbezeichner oder
      der Dateiname des Moduls zum Zeitpunkt seiner Kompilierung sein. 
      rewrite_module beispielsweise ist der Bezeichner und
      mod_rewrite.c ist der Dateiname. Wenn ein Modul aus mehreren
      Quelltext-Dateien besteht, verwenden Sie den Namen der Datei, welche die
      Zeichenfolge STANDARD20_MODULE_STUFF enthält.
    

    
    <IfModule>-Container können
    inneinander verschachtelt werden, um einfache Multi-Modul-Tests
    durchzuführen.
    

    
    Dieser Container sollte verwendet werden, wenn Sie eine
    Konfigurationsdatei benötigen, die unabhängig davon funktioniert,
    ob ein bestimmtes Modul verfügbar ist oder nicht. Normalerweise
    ist es nicht notwendig, Direktiven in <IfModule>-Containern unterzubringen.

    Die Direktive erlaubt das Einfügen anderer Konfigurationsdateien
    in die Konfigurationsdatei des Servers.
    

    
    Shell-typische (fnmatch()) Platzhlaterzeichen können
    dazu verwendet werden, mehrere Dateien auf einmal in alphabetischer
    Reihenfolge einzufügen. Wenn Include
    darüber hinaus auf ein Verzeichnis anstatt auf eine Datei zeigt,
    liest der Apache alle Dateien in diesem Verzeichnis und allen
    Unterverzeichnissen ein. Das Einfügen ganzer Verzeichnisse ist
    jedoch nicht empfehlenswert, da temporäre Dateien sehr leicht
    versehentlich in einem Verzeichnis zurückgelassen werden, was
    httpd scheitern lassen kann.
    

    
    Der angegebene Dateiname kann ein absoluter Pfad sein oder relativ zum
    ServerRoot-Verzeichnis angegeben
    werden.
    

    
    Beispiele:
    

    
    
      Include /usr/local/apache2/conf/ssl.conf
    
      Include /usr/local/apache2/conf/vhosts/*.conf
    
    

    
    Oder Sie geben Pfade relativ zu Ihrem ServerRoot-Verzeichnis an:
    

    
    
      Include conf/ssl.conf
    
      Include conf/vhosts/*.conf
    
    

    
    Der Aufruf von apachectl configtest liefert eine Liste
    der Dateien, die während des Konfigurations-Tests verarbeitet
    werden:
    

    
    
      root@host# apachectl configtest
    
      Processing config file: /usr/local/apache2/conf/ssl.conf

    Status:Core
    

    Modul:core
    

    
    
    Die Keep-Alive-Erweiterung von HTTP/1.0 und die
    HTTP/1.1-Funktionalität persistenter Verbindungen unterstützt
    langlebige HTTP-Sitzungen, die es erlauben, mehrere Anfragen über
    die gleich TCP-Verbindung zu senden. In einigen Fällen wurde eine
    Beschleunigung der Wartezeiten von beinahe 50% für HTML-Dokumente
    mit vielen Bildern festgestellt. Um Keep-Alive-Verbindungen zu aktivieren,
    setzen Sie KeepAlive On.
    

    
    Bei HTTP/1.0-Clients werden Keep-Alive-Verbindungen nur dann verwendet,
    wenn sie vom Client eigens angefordert werden. Desweiteren können
    Keep-Alive-Verbindungen bei einem HTTP/1.0-Client nur dann verwendet
    werden, wenn die Länge des Inhalts im Voraus bekannt ist. Dies
    impliziert, dass dynamische Inhalte wie CGI-Ausgaben, SSI-Seiten und
    servergenerierte Verzeichnisauflistungen im Allgemeinen keine
    Keep-Alive-Verbindungen mit HTTP/1.0-Clients verwenden. Bei
    HTTP/1.1-Clients sind Keep-Alive-Verbindungen Voreinstellung, solange
    nichts anderes angegeben ist. Wenn der Client es anfordert, wird
    Chunked-Encoding verwendet, um Inhalte mit unbekannter Länge
    über persistente Verbindungen zu senden.

    Dies legt die Anzahl der Sekunden fest, die der Apache auf weitere
    Anfragen wartet, bevor er die Verbindung schließt. Nachdem einmal
    eine Anfrage entgegen genommen wurde, wird die durch die Direktive
    Timeout festgelegte Auszeit
    angewendet.
    

    
    Auf stark belasteten Servern kann ein hoher
    KeepAliveTimeout-Wert zu Durchsatzminderungen
    führen. Je höher die Auszeit angegeben ist, desto länger
    ist der Apache damit beschäftigt, auf untätige Clients zu
    warten.

    Zugriffskontrollen gelten normalerweise für alle
    Zugriffsmethoden, was normalerweise auch das gewünschte Verhalten ist.
    Im Allgemeinen sollten Zugriffskontrollen nicht in einen
    <Limit>-Container gepackt
    werden.
    

    
    Der Sinn der Direktive <Limit>
    ist es, den Effekt der Zugriffskontrollen auf die angegebenen
    HTTP-Methoden zu beschränken. Bei allen anderen Methoden haben
    die in der <Limit>-Gruppe
    enthaltenen Zugriffsbeschränkungen keine Wirkung.
    Im folgenden Beispiel gilt die Zugriffskontrolle nur für die
    Methoden POST, PUT und DELETE.
    Alle anderen Methoden bleiben ungeschützt:
    

    
    
      <Limit POST PUT DELETE>
    
      
        Require valid-user
    
          
      </Limit>
    
    

    
    Sie können eine oder mehrere der folgenden Methoden angeben:
    GET, POST, PUT, DELETE,
    CONNECT, OPTIONS,
    PATCH, PROPFIND, PROPPATCH,
    MKCOL, COPY, MOVE,
    LOCK und UNLOCK. Die Methodennamen
    unterscheiden zwischen Groß- und Kleinschreibung. Wenn
    GET verwendet wird, sind HEAD-Anfragen
    ebenfalls eingeschränkt. Die TRACE-Methode kann nicht
    limitiert werden.
    

    
    
      Wenn es um Zugriffsbeschränkungen geht, sollte
      ein <LimitExcept>-Container sollte immer einem <Limit>-Container vorgezogen
      werden, da <LimitExcept>
      einen Schutz gegen beliebige Methoden bietet.

    Modul:core
    

    Kompatibilität:Verfügbar ab Apache 2.0.47
    

    
    
    Eine interne Umleitung erfolgt beispielsweise, wenn die Direktive
    Action verwendet wird, welche
    die Originalanfrage intern zu einem CGI-Skript weiterleitet. Eine
    Unteranfrage (Anm.d.Ü.: engl. Subrequest) ist ein Mechanismus des
    Apache, um herauszufinden, was bei einer URI geschehen würde, wäre
    sie angefordert worden. mod_dir z.B. verwendet
    Unteranfragen, um nach den Dateien zu suchen, die in der DirectoryIndex-Anweisung aufgeführt
    sind.
    
    
    
    LimitInternalRecursion bewahrt den Server vor
      einem Absturz, wenn er in eine Endlosschleife aus internen Umleitungen
      oder Unteranfragen hineinläuft. Derartige Schleifen werden
      gewöhnlich durch Fehlkonfiguration verursacht.
    

    
    Die Direktive setzt zwei verschiedene Begrenzungen, welche je Anfrage
      ausgewertet werden. Die erste Zahl bestimmt die maximale
      Anzahl der Umleitungen, die aufeinander folgen dürfen. Die zweite
      Zahl legt fest, wie tief Unteranfragen ineinander
      verschachtelt werden dürfen. Wenn Sie lediglich eine Zahl
      angeben, wird sie beiden Begrenzungen zugewiesen.

    AllowOverride:All
    

    Status:Core
    

    Modul:core
    

    
    
    Die Direktive gibt die Anzahl der Bytes zwischen 0
    (unbegrenzt) und 2147483647 (2GB) an, die im Request-Body (Datenteil der
    Anfrage) erlaubt sind.
    

    
    Die Direktive LimitRequestBody erlaubt es dem
    Benutzer, die Größe des HTTP-Request-Bodys in dem Kontext zu
    begrenzen, in dem die Anweisung angegeben ist (Server, pro Verzeichnis,
    pro Datei oder pro Adresse). Wenn die Anfrage des Clients dieses Limit
    überschreitet, gibt der Server einen Fehler zurück anstatt die
    Anfrage zu bearbeiten. Die Größe des Datenteils einer Anfrage
    kann sehr stark variieren, abhängig von der Art der Ressource und
    den für diese Ressource erlaubten Methoden. CGI-Skripte verwenden
    den Datenteil üblicherweise zum Empfang von Formulardaten. Wird
    die PUT-Methode angewendet, dann muss der Wert mindestens
    so groß sein wie irgendeine Darstellungsform, die der Server
    für diese Ressource akzeptieren soll.
    

    
    Die Direktive gibt dem Serveradministrator eine größere
    Kontrolle gegenüber abnormalem Verhalten von Clients, was bei der
    Vermeidung einiger Formen von Denial-of-Service-Attacken hilfreich
    sein kann.
    

    
    Wenn Sie beispielsweise das Hochladen von Dateien zu einer bestimmten
    Adresse erlauben, aber die Größe der hochgeladenen Dateien
    auf 100K beschränken wollen, können Sie die folgende Anweisung
    verwenden:
    

    
    
      LimitRequestBody 102400

    Kontext:Serverkonfiguration

    Anzahl ist ein Integer-Wert (eine positive Ganzzahl)
    zwischen 0 (unbegrenzt) und 32767. Die Voreinstellung wird durch die
    Konstante DEFAULT_LIMIT_REQUEST_FIELDS (100
    bei der Auslieferung) zur Kompilierungszeit gesetzt.
    

    
    Die Direktive LimitRequestFields erlaubt es
    dem Serveradministrator, die maximale Anzahl der in einem HTTP-Request
    erlaubten HTTP-Request-Header zu verändern. Für den Server
    muss dieser Wert größer sein als die Anzahl der Headerzeilen,
    die ein normaler Client senden könnte. Die Anzahl der Request-Header,
    die ein gewöhnlicher Client verwendet, überschreitet selten 20
    Zeilen. Allerdings kann dies zwischen den verschiedenen
    Client-Ausführungen variieren, oft abhängig vom Ausmaß,
    mit dem der Anwender die genaue Content-Negotiation-Unterstützung
    seines Browsers konfiguriert hat. Optionale HTTP-Erweiterungen
    äußern sich oft in Form von HTTP-Headern.
    

    
    Die Direktive gibt dem Serveradministrator eine größere
    Kontrolle gegenüber abnormalem Verhalten von Clients, was bei der
    Vermeidung einiger Formen von Denial-of-Service-Attacken hilfreich
    sein kann. Der Wert sollte erhöht werden, wenn normale Clients
    eine Fehlermeldung vom Server erhalten, die besagt, dass mit der Anfrage
    zu viele Headerzeilen gesendet wurden.

    Die Direktive gibt die Anzahl der Bytes an, die in einem

    Die Direktive LimitRequestFieldsize erlaubt es
    dem Serveradministrator, die maximale Größe eines
    HTTP-Request-Headers zu verringern oder erhöhen. Für den Server
    muss der Wert groß genug sein, um eine beliebige Headerzeile einer
    normalen Client-Anfrage vorzuhalten. Die Größe variiert stark
    zwischen den verschiedenen Client-Ausführungen, oft abhängig vom
    Ausmaß, mit dem der Anwender die genaue
    Content-Negotiation-Unterstützung seines Browsers konfiguriert hat.

    Die Direktive gibt dem Serveradministrator eine größere
    Kontrolle gegenüber abnormalem Verhalten von Clients, was bei der
    Vermeidung einiger Formen von Denial-of-Service-Attacken hilfreich
    sein kann.
    

    
    Beispiel:
    

    
    
      LimitRequestFieldSize 4094

    Die Direktive legt die Anzahl der Bytes fest, die in der
    HTTP-Anfragezeile erlaubt sind.
    

    
    Die Direktive LimitRequestLine erlaubt es dem
    Serveradministrator, die maximale Größe der
    HTTP-Anfragezeile zu verringern oder erhöhen. Da
    die Anfragezeile aus der HTTP-Methode, der URI und der Protokollversion
    besteht, bedeutet die LimitRequestLine-Direktive
    eine Beschränkung der Länge der für eine Anfrage an den
    Server erlaubten Anfrage-URI. Für den Server muss der Wert groß
    genug sein, um jeden seiner Ressourcennamen vorzuhalten,
    einschließlich aller Informationen, die im Query-String einer
    GET-Anfrage übergeben werden können.

    <Location>-Direktive
    

    

    Beschreibung:Wendet die enthaltenen Direktiven nur auf die entsprechenden
URLs an
    

    Syntax:<Location
    URL-Pfad|URL> ... </Location>
    

    Kontext:Serverkonfiguration, Virtual Host
    

    Status:Core
    

    Modul:core
    

    
    
    Die Direktive <Location>
    begrenzt die Reichweite der enthaltenen Anweisungen auf URLs.
    Sie ist der Direktive <Directory> ähnlich und startet einen
    Abschnitt, der mit der Anweisung </Location>
    abgeschlossen wird. <Location>-Container werden, nachdem die
    <Directory>-Container
    und .htaccess-Dateien gelesen wurden, und nach den
    <Files>-Containern, in
    der Reihenfolge ausgeführt, in der sie in der Konfigurationsdatei
    erscheinen.
    

    
    <Location>-Abschnitte operieren
      vollständig außerhalb des Dateisystems. Dies hat mehrere
      Konsequenzen. An Wichtigsten, <Location>-Anweisungen sollten nicht dafür
      verwendet werden, den Zugriff zu Teilen des Dateisystems zu steuern. Da
      mehrere unterschiedliche URLs auf die gleiche Stelle des Dateisystems
      zeigen können, könnte eine solche Zugriffskontrolle u.U.
      umgangen werden.
    
      
    
    Wann sollte<Location> verwendet werden
    

      
    Verwenden Sie <Location>, um
        Anweisungen auf Inhalte anzuwenden, die außerhalb des Dateisystems
        abgelegt sind. Benutzen Sie <Directory> und <Files> für Inhalte, die
        innerhalb des Dateisystems abgelegt sind. Eine Ausnahme bildet 
        <Location />, welches ein einfacher Weg ist, um eine 
        Konfiguration auf den gesamten Server anzuwenden.
    
    
    
 
    
    Für alle nicht-Proxy-Anfragen ist die entsprechende URL
    ein URL-Pfad in der Form /path/. Es dürfen weder ein
    Schema, noch ein Hostname, noch ein Port, noch ein Query-String einbezogen
    werden. Für Proxy-Anfragen hat die Vergleichs-URL die Form
    schema://servername/path. Das Präfix muss angegeben
    werden.
    

    
    Die URL kann Platzhalter verwenden. In einer Zeichenfolge mit
    Platzhaltern entspricht ? einem einzelnen Zeichen und
    *einer beliebigen Zeichenfolge.
    

    
    Erweiterte reguläre
    Ausdrücke können ebenfalls verwendet werden, indem
    das Zeichen ~ hinzugefügt wird. Beispielsweise
    würde
    

    
    
      <Location ~ "/(extra|special)/data">
    
    

    
    auf URLs passen, welche die Zeichenfolge /extra/data
    oder /special/data enthalten. Die Direktive <LocationMatch> verhält sich
    genauso wie <Location> mit
    regulären Ausdrücken.
    

    
    Die Funktionalität von <Location> ist insbesondere dann nützlich,
    wenn sie mit der SetHandler-Direktive
    kombiniert wird. Um zum Beispiel Statusabfragen zu aktivieren, sie aber
    nur von Browsern aus foo.com zuzulassen, könnten Sie
    schreiben:
    

    
    
      <Location /status>
    
      
        SetHandler server-status
    
        Order Deny,Allow
    
        Deny from all
    
        Allow from .foo.com
    
          
      </Location>
    
    

    
    Anmerkung zu / (Schrägstrich, Slash)
    
      
    Das Slash-Zeichen hat eine besondere Bedeutung, je nachdem, wo es
      in der URL erscheint. Manche werden sein Verhalten vom Dateisystem
      gewohnt sein, wo mehrere aufeinanderfolgende Schrägstriche
      häufig zu einem Schrägstrich zusammengefaßt werden
      (d.h. /home///foo ist das gleiche wie
      /home/foo). Im URL-Raum ist dies nicht notwendigerweise
      genauso. Bei der Direktive  <LocationMatch> und der <Location>-Version mit regulären Ausdrücken
      müssen Sie explizit mehrere Schrägstriche angeben, wenn Sie
      genau dies beabsichtigen.
    

      
    Beispielsweise würde <LocationMatch ^/abc>
      auf die angeforderte URL /abc passen, nicht aber auf
      //abc. Die Direktive <Location> (ohne reguläre Ausdrücke) verhält
      sich ähnlich, wenn sie für Proxy-Anfragen verwendet wird.
      Wenn <Location> (ohne
      reguläre Ausdrücke) jedoch für nicht-Proxy-Anfragen
      verwendet wird, werden stillscheigend mehrere Schrächstriche mit
      mit einem einzigen Schrägstrich gleichgesetzt. Geben Sie
      beispielsweise <Location /abc/def> an und die
      Anfrage lautet auf /abc//def, dann greift die Anweisung.

    Kontext:Serverkonfiguration
    

    Status:Core
    

    Modul:core
    

    
    
    Die Direktive NameVirtualHost ist erforderlich,
    wenn Sie namensbasierte virtuelle Hosts
    konfigurieren möchten.
    

    
    Obwohl Adresse eine Hostname sein kann, wird empfohlen,
    dass Sie stets eine IP-Adresse verwenden, z.B.:
    

    
    
      NameVirtualHost 111.22.33.44
    
    

    
    Mit der NameVirtualHost-Anweisung geben Sie
    die IP-Adresse an, unter der der Server Anfragen für
    namensbasierte virtuelle Hosts entgegennimmt. Das ist üblicherweise
    die Adresse, zu der die Namen Ihrer namensbasierten virtuellen Hosts
    aufgelöst werden. Falls eine Firewall oder ein anderer Proxy die
    Anfrage in Empfang nimmt und Sie zu einer weiteren IP-Adresse des Servers
    weiterleitet, müssen Sie die IP-Adresse der physikalischen
    Schnittstelle der Maschine angeben, welche die Anfragen bedient.
    Wenn Sie mehrere namensbasierte Hosts an verschiedenen Adressen
    betreiben, wiederholen Sie einfach die Anweisung für jede
    Adresse.
    

    
    Anmerkung
    
      
    Beachten Sie, dass der "Hauptserver" und jeder
      _default_-Server niemals bei einer
      Anfrage an einer NameVirtualHost-IP-Adresse
      bedient wird (es sei denn, Sie geben aus irgendwelchen Gründen
      NameVirtualHost an, definieren dann aber keine
      VirtualHosts für diese Adresse).
    
    
    

    
    Optional können Sie die Nummer eines Ports angeben, an dem
    namensbasierte virtuelle Hosts verwendet werden sollen. Beispiel:
    

    
    
      NameVirtualHost 111.22.33.44:8080
    
    

    
    IPv6-Adressen müssen, wie im folgenden Beispiel angegeben, in
    eckige Klammern eingeschlossen werden:
    

    
    
      NameVirtualHost [2001:db8::a00:20ff:fea7:ccea]:8080
    
    

    
    Um an allen Schnittstellen Anfragen zu empfangen, können Sie
    * als Argument verwenden.
    

    
    
      NameVirtualHost *
    
    

    
    Argument der Direktive <VirtualHost>
    
      
    Beachten Sie, dass das Argument der <VirtualHost>-Anweisung exakt auf das Argument
      der NameVirtualHost-Anweisung passen muss.
    

      
    
        NameVirtualHost 1.2.3.4
    
        <VirtualHost 1.2.3.4>
    
        # ...

        mod_negotiation erlaubt (siehe Content-Negotiation).
    

      
    SymLinksIfOwnerMatch
    

      
    Der Server folgt nur symbolischen Links, bei denen die Zieldatei
      bzw. das Zielverzeichnis der gleichen Benutzerkennung gehört, wie
      der Link.
      
    Anmerkung
     Diese Option wird innerhalb eines
      <Location>-Abschnitts
      ignoriert.
    
    
    

    
    Wenn mehrere Options auf ein Verzeichnis
    angewandt werden können, dann wird normalerweise die
    spezifischste (Anm.d.Ü.: Gemeint ist die zuletzt
    ausgeführte Option.) verwendet und alle anderen werden
    ignoriert; die Optionen werden nicht vermischt. (Siehe auch Wie Abschnitte zusammengeführt 
    werden..) Wenn jedoch allen Optionen der 
    Options-Anweisung eines der Zeichen
    + oder - vorangestellt wird, werden die Optionen
    zusammengemischt. Jede Option mit vorangestelltem + wird
    zu den momentan gültigen Optionen hinzugefügt und jede Option
    mit vorangestelltem - wird aus den derzeit gültigen
    Optionen entfernt.
    

    
    Warnung
    
    
    Die Vermischung von Optionen mit + oder - mit
    Optionen ohne diese (Zeichen) ist keine gültige Syntax und führt
    mit hoher Wahrscheinlichkeit zu unerwarteten Effekten.
    
    
    

    
    So wird zum Beispiel ohne die Zeichen + und
    -
    

    
    
      <Directory /web/docs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
      
    
      <Directory /web/docs/spec>
    
      
        Options Includes
    
          
      </Directory>
    
    

    
    für das Verzeichnis /web/docs/spec wird jetzt
    lediglich Includes gesetzt. Wenn die zweite
    Options-Anweisung jedoch +-
    und --Zeichen verwenden würde,
    

    
    
      <Directory /web/docs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
      
    
      <Directory /web/docs/spec>
    
      
        Options +Includes -Indexes
    
          
      </Directory>
    
    

    
    dann würden die Optionen FollowSymLinks und
    Includes für das Verzeichnis /web/docs/spec
    gesetzt.
    

    
    Anmerkung
    
      
    Die Verwendung von -IncludesNOEXEC oder
      -Includes deaktiviert Server Side Includes unabhängig
      von der vorigen Einstellung vollständig.
    
    
    

    
    Die Voreinstellung ist All, sofern keine anderen Angaben

    ScriptInterpreterSource-Direktive
    

    

    Beschreibung:Methode zur Ermittlung des Interpreters von
CGI-Skripten
    

    Syntax:ScriptInterpreterSource Registry|Registry-Strict|Script
    

    Voreinstellung:ScriptInterpreterSource Script
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis, .htaccess
    

    AllowOverride:FileInfo
    

    Status:Core
    

    Modul:core
    

    Kompatibilität:ausschließlich Win32;
Die Option Registry-Strict ist verfügbar seit Apache
2.0.
    

    
    
    Die Direktive steuert, wie der Apache den Interpreter zur Ausführung
    von CGI-Skripten bestimmt. Die Voreinstellung ist Script. Dies
    veranlaßt den Apache, den Interpreter zu verwenden, auf den die
    Shebang-Zeile (erste Zeile, beginnt mit #!) im Skript zeigt.
    Auf Win32-Systemen sieht diese Zeile üblicherweise so aus:
    

    
    
      #!C:/Perl/bin/perl.exe
    
    

    
    oder, wenn perl im Pfad (Umgebungsvariable PATH) liegt,
      einfach:
    

    
    
      #!perl
    
    

    
    Die Einstellung ScriptInterpreterSource Registry
    veranlaßt eine Suche in HKEY_CLASSES_ROOT der
    Windows-Registrierungsdatenbank und verwendet die Endung der Skript-Datei
    (z.B. .pl) als Suchargument. Der durch den Unterschlüssel
    Shell\ExecCGI\Command oder, falls dieser nicht existiert,
    Shell\Open\Command definierte Befehl wird zum Öffnen der
    Skript-Datei verwendet. Wenn der Schlüssel zur Dateiendung oder
    beide Unterschlüssel fehlen, dann verwendet der Apache die Option
    Script.
    

    
    Sicherheit
    
      
    Seien Sie vorsichtig, ScriptInterpreterSource Registry bei
      Verzeichnissen zu verwenden, auf die eine ScriptAlias-Anweisung zeigt, denn der
      Apache versucht jede Datei innerhalb des Verzeichnisses
      auszuführen. Die Einstellung Registry kann
      unerwünschte Programmaufrufe bei Dateien verursachen, die
      üblicherweise nicht ausgeführt werden. Auf den meisten
      Windows-Systemen beispielsweise startet der voreingestellte
      Öffnen-Befehl für .htm-Dateien den Microsoft
      Internet Explorer, so dass jede HTTP-Anfrage nach einer existierenden
      .htm-Datei im Skript-Verzeichnis den Browser im Hintergrund
      starten würde. Dies ist eine wirksame Methode, Ihr System binnen
      etwa einer Minute zum Absturz zu bringen.
    
    
    
          
    
    Die seit Apache 2.0 neue Option Registry-Strict
    macht das gleiche wie Registry, verwendet jedoch nur den
    Unterschlüssel Shell\ExecCGI\Command. Der Schlüssel
    ExecCGI ist gewöhnlich nicht voreingestellt. Er muss
    manuell eingerichtet werden und schützt Ihr System so for
    versehentlichen Programmaufrufen.

    ServerAdmin legt die Kontaktadresse fest,

    Client zurückschickt. Wenn httpd das übergebene
    Argument nicht als URL erkennt, nimmt er an, dess es sich um eine
    E-Mail-Adresse handelt und stellt in Hyperlinks
    mailto: voran. Es ist jedoch sogar sinnvoll, eine
    E-Mail-Adresse zu verwenden, da viele CGI-Skripte davon ausgehen. Wenn Sie
    eine URL verwenden möchten, sollten Sie auf einem anderen unter Ihrer
    Kontrolle stehenden Server verweisen. Andernfalls können Besucher Sie
    im Fehlerfall möglicherweise nicht kontaktieren.
    

    
    Es kann sich lohnen, hierfür eine reservierte Adresse
    anzugeben, z.B.

    Modul:core
    

    Kompatibilität:Diese Direktive löst in Version 2.0 die
     Funktionalität der Direktive Port aus
     Version 1.3 ab.
    

    
    
    Die Direktive ServerName bestimmt den
    Rechnernamen und Port, den der Server dazu verwendet, sich selbst
    zu identifizieren. Diese werden bei der Erstellung von Umleitungs-URLs
    benötigt. Wenn beispielsweise der Name der Maschine, die den Webserver
    beherbergt, simple.example.com lautet, die Maschine jedoch
    auch einen DNS-Alias www.example.com besitzt und Sie den
    Webserver so identifizieren möchten, sollten Sie die folgende
    Anweisung verwenden:
    

    
    
      ServerName www.example.com:80
    
    

    
    Wenn kein ServerName angegeben wurde,
    dann versucht der Server den Rechnernamen mittels eines Reverse-Lookup
    herzuleiten. Wenn kein Port in der
    ServerName-Anweisung angegeben wurde, dann
    verwendet der Server den Port der eingegangenen Anfrage. Für eine
    optimale Zuverlässigkeit und Berechenbarkeit sollten Sie einen
    eindeutigen Rechnernamen und Port angeben, in dem Sie die Direktive
    ServerName verwenden.
    

    
    Wenn Sie namensbasierte
    virtuelle Hosts verwenden, gibt ServerName
    innerhalb eines <VirtualHost>-Abschnitts an, welcher
    Hostname im Host:-Header der Anfrage auftauchen muss,
    damit sie diesem virtuellen Host zugeordnet wird.
    

    
    Lesen Sie bitte die Beschreibung der Direktiven UseCanonicalName und UseCanonicalPhysicalPort für Einstellungen, die
    bestimmen, ob selbstreferenzierende URLs (z.B. vom Modul
    mod_dir) auf den angegebenen Port zeigen oder auf die
    Portnummern die in der Anfrage des Clients angegeben ist.

    Die Direktive ServerSignature ermöglicht
    die Gestaltung einer unter servergenerierten Dokumenten (z.B.
    Fehlerdokumente, FTP-Verzeichnislisten von mod_proxy,
    mod_info-Ausgaben, ...) angefügten
    Fußzeile. Ein möglicher Grund für die Aktivierung einer
    solchen Fußzeile ist, dass der Anwender bei einer Kette von
    Proxy-Servern oft keine Möglichkeit hat, zu erkennen, welcher der
    verketteten Server gegenwärtig die zurückgegebene Fehlermeldung
    produziert hat.
    

    
    Die (Vor-)Einstellung Off unterdrückt die
    Fußzeile (und ist damit kompatibel zum Verhalten des Apache 1.2 und
    früher). Die Einstellung On fügt schlicht eine
    Zeile mit der Versionsnummer des Servers und dem Servernamen (ServerName) des bedienenden virtuellen Hosts an.
    Die Einstellung EMail erstellt zusätzlich einen
    "mailto:"-Verweis zum Serveradministrator (ServerAdmin) des referenzierten Dokuments.
    

    
    Ab Version 2.0.44 werden die Details der angegebenen Versionsnummer des
    Servers von der Direktive  ServerTokens kontrolliert.

    SetHandler-Direktive
    

    

    Beschreibung:Erzwingt die Verarbeitung aller passenden Dateien durch
einen Handler
    

    Syntax:SetHandler Handlername|None
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis, .htaccess
    

    AllowOverride:FileInfo
    

    Status:Core
    

    Modul:core
    

    Kompatibilität:Seit Apache 2.0 im Core
    

    
    
    Wenn die Direktive innerhalb einer .htaccess-Datei
    oder in einem <Directory>- oder
    <Location>-Abschnitt
    angegeben wird, erzwingt sie, dass alle entsprechenden Dateien von dem
    durch Handlername angegebenen Handler analysiert werden. Wenn Sie
    beispielsweise ein Verzeichnis haben, dessen Dateien unabhängig von
    der Endung gänzlich als Image-Maps interpretiert werden sollen,
    können Sie folgendes in eine .htaccess-Datei in
    dem Verzeichnis schreiben:
    

    
    
      SetHandler imap-file
    
    

    
    Noch ein Beispiel: wenn Sie den Server immer, wenn die URL
    http://servername/status aufgerufen wird, einen
    Statusbericht anzeigen lassen möchten, dann können
    Sie folgendes in die httpd.conf schreiben:
    

    
    
      <Location /status>
    
      
        SetHandler server-status
    
          
      </Location>
    
    
    
    Sie können eine zuvor definierte
    SetHandler-Anweisung aufheben, indem Sie den Wert
    None verwenden.
    
    
    Hinweis: SetHandler setzt die Standard-Handler
    außer Kraft und unterdrückt gewohnte Verhaltensweisen, wie
    beispielsweise die Behandlung von URLs, die auf einen Schrägstrich
    (/) enden als Verzeichnisse oder (die Auslieferung von) Index-Dateien.

    Die Direktive TimeOut definiert derzeit die
    Zeitspanne, die der Apache auf drei Dinge wartet:
    

    
      
      
    1. Die gesamte Zeispanne, die benötigt wird, um eine GET-Anfrage
      zu empfangen.
      2. 

      
    2. Die Zeitspanne zwischen dem Empfang von TCP-Paketen einer
      POST- oder PUT-Anfrage.
      3. 

      
    3. Die Zeitspanne zwischen ACKs bei der Übermittlung der
      TCP-Pakete der Antwort.
      4. 
    
    

    
    Wir haben vor, diese Zeitspannen in Zukunft separat konfigurierbar zu
    machen. Vor Version 1.2 war der Zeitgeber auf 1200 voreingestellt, wurde
    dann aber auf 300 herabgesetzt, was immer noch weit mehr ist, als in den
    meisten Situationen benötigt wird. Die Voreinstellung wurde nicht
    weiter herabgesetzt, da gelegentlich noch Stellen im Code existieren
    können, wo der Zeitgeber nicht zurückgesetzt wird, wenn ein
    Paket verschickt wird. Seit Apache 2.4 ist die Voreinstellung 60.

    TraceEnable-Direktive

    Voreinstellung:TraceEnable on
    

    Kontext:Serverkonfiguration

    Modul:core
    

    Kompatibilität:Verfügbar ab Apache 1.3.34 und 2.0.55
    

    
    
    Diese Direktive beeinflusst das Verhalten von TRACE sowohl
    für den Server selbst als auch mod_proxy. Die
    Voreinstellung TraceEnable on erlaubt
    TRACE-Anfragen gemäß RFC 2616. Dort werden
    nur Anfragen ohne Datenteil zugelassen. TraceEnable off
    sorgt dafür, dass der Serverkern und mod_proxy den
    Fehler 405 (Zugriffsmethode nicht erlaubt) an den Client
    senden.
    

    
    Zu Test- und Diagnosezwecken können Sie auch
    nicht-standardkonforme Anfragen mit Datenteil erlauben, indem Sie die
    Direktive TraceEnable extended verwenden. Der Server (als
    Ursprungsserver) beschränkt den Anfrageinhalt auf 64k. (Wenn
    Transfer-Encoding: chunked benutzt wird, können
    weitere 8k für die Chunk-Kopfzeilen verwendet werden.) Der
    Server selbst reflektiert dann die vollständigen HTTP- und
    Chunk-Kopfzeilen in seiner Antwort. Die Einschränkung auf 64k gilt
    nicht, wenn der Server als Proxy arbeitet.

    UseCanonicalName-Direktive
    

    

    Beschreibung:Bestimmt, wie der Server seinen eigenen Namen und Port
ermittelt
    

    Syntax:UseCanonicalName On|Off|DNS
    

    Voreinstellung:UseCanonicalName Off
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis
    

    Status:Core
    

    Modul:core
    

    
    
    In vielen Situationen muss der Apache eine
    selbstreferenzierende URL -- d.h. eine URL, die auf den selben
    Server zurück verweist -- zusammenbauen. Bei UseCanonicalName
    On verwendet der Apache den Hostnamen und Port, der in der
    ServerName-Anweisung angegeben ist,
    um den kanonischen Namen des Servers zu erstellen. Dieser Name wird in
    allen selbstreferenzierenden URLs sowie in CGI-Skripten für die
    Werte von SERVER_NAME und SERVER_PORT
    verwendet.
    

    
    Bei UseCanonicalName Off bildet der Apache
    selbstreferenzierende URLs, indem er den vom Client übermittelten
    Hostnamen und Port verwendet, sofern diese vorhanden sind (andernfalls
    wird der kanonische Name, wie oben beschrieben, benutzt). Die Werte
    sind die gleichen, die zur Anwendung von namensbasierten virtuellen Hosts
    verwendet werden, und sie sind mit den gleichen Clients verfügbar
    (Anm.d.Ü.: , die auch in der Lage sind, auf namensbasierte virtuelle Hosts
    zuzugreifen, d.h. einen Host-Header mitschicken).
    Die CGI-Variablen SERVER_NAME und SERVER_PORT
    werden ebenfalls aus den vom Client angeboten Werten erstellt.
    

    
    Ein Intranet-Server, auf den Anwender mit kurzen Namen wie
    www zugreifen, ist ein Beispiel, wo dies sinnvoll sein kann.
    Sie werden bemerken, dass der Apache den Benutzer auf
    http://www.domain.com/splat/ umleitet, wenn dieser einen
    Kurznamen und eine URL, die einem Verzeichnis entspricht, ohne
    abschließenden Schrägstrich eingibt, wie z.B.
    http://www/splat. Wenn Sie Authentisierung aktiviert haben,
    bewirkt dies, dass der Benutzer sich zweimal identifizieren muss
    (einmal für www und noch einmal für
    www.domain.com -- lesen Sie für weitere Informationen die
    FAQ zu diesem Thema). Wenn UseCanonicalName
    jedoch auf Off gesetzt ist, denn wird der Apache zu
    http://www/splat/ umleiten.
    

    
    Es existiert noch eine dritte Option, UseCanonicalName DNS,
    die für den Betrieb von IP-basierten Massen-Virtual-Hosts gedacht ist,
    um antiquierte Clients zu unterstützen, die keinen
    Host:-Header bereit stellen. Um selbstreferenzierende
    URLs zu ermitteln, führt der Apache bei dieser Option ein
    Reverse-DNS-Lookup auf die IP-Adresse des Servers aus, zu der der Client
    Verbindung aufgenommen hat.
    

    
    Warnung
    
      
    Wenn CGI-Skripte Vermutungen aufgrund des Wertes von
      SERVER_NAME anstellen, können sie durch diese
      Option fehlschlagen. Clients steht es im Wesentlichen frei, einen Wert
      für den Hostnamen anzugeben, wie er will. Wenn das
      CGI-Skript SERVER_NAME jedoch lediglich dazu verwendet,
      selbstreferenzierende URLs zu erstellen, sollte das gerade noch
      in Ordnung sein.

    UseCanonicalPhysicalPort-Direktive

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis
    

    Status:Core
    

    Modul:core
    

    
    
    In vielen Situationen muss der Apache eine
    selbstreferenzierende URL zusammenbauen, d.h. eine URL, die auf
    den selben Server zurück verweist. Wenn der Apache für die
    UseCanonicalName-Direktive den Port
    bestimmt, wird mit UseCanonicalPhysicalPort On die
    tatsächlich für die Anfrage verwendete physische Portnummer
    in Betracht gezogen. Mit UseCanonicalPhysicalPort Off
    verläßt sich der Apache nur auf die Konfiguration, um eine
    gültige Portnummer zu bestimmen und läßt die
    physische Portnummer außer acht.
    

    
    Hinweis
    
    
    Wenn der physische Port verwendet wird, ist die Reihenfolge wie
    folgt:

    
     UseCanonicalName On
    
     
      
      
    • Der in Servername angegebene Port
      • 
      
    • Der physische Port
      • 
      
    • Der Standardport
      • 
     
    
     UseCanonicalName Off | DNS
     
      
      
    • Der Port, der aus dem Host:-Header gewonnen wurde
      • 
      
    • Der physische Port
      • 
      
    • Der in Servername angegebene Port
      • 
      
    • Der Standardport
      • 
     
    

    
    Bei UseCanonicalPhysicalPort Off werden die physischen
    Ports aus der Suchreihe entfernt.

    <VirtualHost>-Direktive
    

    

    Beschreibung:Enthält Direktiven, die nur auf bestimmte Hostnamen oder
IP-Adressen angewendet werden
    

    Syntax:<VirtualHost
    Adresse[:Port] [Adresse[:Port]]
    ...> ... </VirtualHost>
    

    Kontext:Serverkonfiguration
    

    Status:Core
    

    Modul:core
    

    
    
    <VirtualHost> und
    </VirtualHost> werden dazu verwendet, eine Gruppe
    von Direktiven zusammenzufassen, die nur auf einen bestimmten virtuellen
    Host angewendet werden. Jede Direktive, die im Virtual-Host-Kontext
    zulässig ist, kann verwendet werden. Wenn der Server eine Anfrage
    für ein bestimmtes Dokument eines bestimmten virtuellen Hosts
    empfängt, dann benutzt er die im
    <VirtualHost>-Container enthaltenen
    Konfigurationsanweisungen. Adresse kann sein:
    

    
      
      
    • Die IP-Adresse des virtuellen Hosts.
      • 

      
    • Ein voll qualifizierter Domainname für die IP-Adresse des
      virtuellen Hosts.
      • 

      
    • Das Zeichen *, welches nur in Kombination mit
      NameVirtualHost * verwendet wird, um allen IP-Adressen
      zu entsprechen.
      • 

      
    • Die Zeichenkette _default_, die nur mit IP-basierten
      virtuellen Hosts verwendet wird, um nicht zugewiesene IP-Adressen
      aufzufangen.
      • 
    
    

    
    Beispiel
    
      <VirtualHost 10.1.2.3>
    
      
        ServerAdmin webmaster@host.foo.com
    
        DocumentRoot /www/docs/host.foo.com
    
        ServerName host.foo.com
    
        ErrorLog logs/host.foo.com-error_log
    
        TransferLog logs/host.foo.com-access_log
    
          
      </VirtualHost>
    
    

    
    IPv6-Adressen müssen in eckigen Klammern angegeben werden, da die
    optionale Portnummer sonst nicht erkannt werden kann. Hier ein
    IPv6-Beispiel:
    

    
    
      <VirtualHost [2001:db8::a00:20ff:fea7:ccea]>
    
      
        ServerAdmin webmaster@host.example.com
    
        DocumentRoot /www/docs/host.example.com
    
        ServerName host.example.com
    
        ErrorLog logs/host.example.com-error_log
    
        TransferLog logs/host.example.com-access_log
    
          
      </VirtualHost>
    
    

    
    Jeder virtuelle Host muss einer anderen IP-Adresse, einem anderen Port
    oder einem anderen Hostnamen für den Server entsprechen. Im ersten
    Fall muss die Servermaschine so eingerichtet sein, dass sie IP-Pakete
    für mehrere Adressen akzeptiert. (Wenn der Rechner nicht mehrere
    Netzwerkkarten besitzt, kann dies mit dem Befehl ifconfig
    alias durchgeführt werden -- sofern Ihr Betriebssystem das
    unterstützt).
    

    
    Anmerkung
    
      
    Die Verwendung von <VirtualHost>
      beeinflusst nicht, an welchen Adressen der Apache
      lauscht. Sie müssen mit Listen sicherstellen, dass der Apache
      an der richtigen Adresse lauscht.
    
    
    

    
    Bei der Verwendung IP-basierter virtuellen Hosts kann der spezielle
    Name _default_ benutzt werden. In diesem Fall weist
    der Apache jede IP-Adresse diesem virtuellen Host zu, die nicht explizit in
    einem anderen virtuellen Host angegeben ist. Falls kein virtueller Host
    _default_ angegeben ist, wird die "Hauptserver"-Konfiguration,
    die aus allen Definitionen außerhalb der Virtual-Host-Abschnitte
    besteht, für nicht passende IPs verwendet. (Beachten Sie jedoch,
    dass eine IP-Adressen die zu einer NameVirtualHost-Anweisung passt, weder den
    "Hauptserver" noch den virtuellen Host _default_ verwendet.
    Lesen Sie für weitere Details die Dokumentation zu namensbasierten virtuell Hosts.)
    

    
    Sie können einen speziellen :Port angeben,
    um den entsprechenden Port zu wechseln. Falls nicht angegeben, wird
    er auf den gleichen Port voreingestellt, wie die letzte
    Listen-Anweisung des
    Hauptservers. Sie können auch :* angeben, um alle
    Ports dieser Adresse zu akzeptieren. (Dies wird zusammen mit
    _default_ empfohlen.)
    

    
    Sicherheit
    
      
    Lesen Sie das Dokument Sicherheitshinweise für
      Details, warum Ihre Sicherheit gefährdet sein kann, wenn das
      Verzeichnis, in dem Protokolldateien gespeichert werden, für
      jemanden anderes als den Benutzer beschreibbar ist, der den Server
      gestartet hat.

    Source File:mod_deflate.c
    

    Summary
    

    
    The mod_deflate module provides
    the DEFLATE output filter that allows output from
    your server to be compressed before being sent to the client over
    the network.

    Supported Encodings
    
  
    The gzip encoding is the only one supported to ensure complete compatibility
  with old browser implementations. The deflate encoding is not supported, 
  please check the zlib's documentation
  for a complete explanation.

    Sample Configurations
    
    
    Compression and TLS
    
        
    Some web applications are vulnerable to an information disclosure
        attack when a TLS connection carries deflate compressed data. For more
        information, review the details of the "BREACH" family of attacks.
    
    
    
    
    This is a simple configuration that compresses common text-based content types.
    

    
    Compress only a few types
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript

    Enabling Compression
    
    
    Compression and TLS
    
        
    Some web applications are vulnerable to an information disclosure
        attack when a TLS connection carries deflate compressed data. For more
        information, review the details of the "BREACH" family of attacks.
    
    
    

    
    Output Compression
    
      
    Compression is implemented by the DEFLATE
      filter. The following directive
      will enable compression for documents in the container where it
      is placed:
    

      
    SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI "\.(?:gif|jpe?g|png)$" no-gzip
    


      
    If you want to restrict the compression to particular MIME types
      in general, you may use the AddOutputFilterByType directive. Here is an example of
      enabling compression only for the html files of the Apache
      documentation:
    

      
    <Directory "/your-server-root/manual">
    AddOutputFilterByType DEFLATE text/html
</Directory>
    


      
    Note
    
        The DEFLATE filter is always inserted after RESOURCE
        filters like PHP or SSI. It never touches internal subrequests.
      
    
      
    Note
    
        There is an environment variable force-gzip,
        set via SetEnv, which
        will ignore the accept-encoding setting of your browser and will
        send compressed output.
      
    

    
    
    Output Decompression
    
      
    The mod_deflate module also provides a filter for
      inflating/uncompressing a gzip compressed response body. In order to activate
      this feature you have to insert the INFLATE filter into
      the output filter chain using SetOutputFilter or AddOutputFilter, for example:
    

      
    <Location "/dav-area">
    ProxyPass "http://example.com/"
    SetOutputFilter INFLATE
</Location>
    


      
    This Example will uncompress gzip'ed output from example.com, so other
      filters can do further processing with it.
      
    

    
    
    Input Decompression
    
      
    The mod_deflate module also provides a filter for
      decompressing a gzip compressed request body . In order to activate
      this feature you have to insert the DEFLATE filter into
      the input filter chain using SetInputFilter or AddInputFilter, for example:
    

      
    <Location "/dav-area">
    SetInputFilter DEFLATE
</Location>
    


      
    Now if a request contains a Content-Encoding:
      gzip header, the body will be automatically decompressed.
      Few browsers have the ability to gzip request bodies. However,
      some special applications actually do support request
      compression, for instance some WebDAV clients.
    

      
    Note on Content-Length
    
        
    If you evaluate the request body yourself, don't trust
        the Content-Length header!
        The Content-Length header reflects the length of the
        incoming data from the client and not the byte count of
        the decompressed data stream.

    Dealing with proxy servers
    

    
    The mod_deflate module sends a Vary:
    Accept-Encoding HTTP response header to alert proxies that
    a cached response should be sent only to clients that send the
    appropriate Accept-Encoding request header.  This
    prevents compressed content from being sent to a client that will
    not understand it.
    

    
    If you use some special exclusions dependent
    on, for example, the User-Agent header, you must
    manually configure an addition to the Vary header
    to alert proxies of the additional restrictions.  For example,
    in a typical configuration where the addition of the DEFLATE
    filter depends on the User-Agent, you should add:
    

    
    Header append Vary User-Agent
    


    
    If your decision about compression depends on other information
    than request headers (e.g. HTTP version), you have to set the
    Vary header to the value *. This prevents
    compliant proxies from caching entirely.
    

    
    Example
    Header set Vary *
    

    

    top
    

    

    Serving pre-compressed
content
    

    
    Since mod_deflate re-compresses content each
    time a request is made, some performance benefit can be derived by
    pre-compressing the content and telling mod_deflate to serve them
    without re-compressing them. This may be accomplished using a
    configuration like the following:
    

    
    <IfModule mod_headers.c>
    # Serve gzip compressed CSS and JS files if they exist
    # and the client accepts gzip.
    RewriteCond "%{HTTP:Accept-encoding}" "gzip"
    RewriteCond "%{REQUEST_FILENAME}\.gz" -s
    RewriteRule "^(.*)\.(css|js)"         "$1\.$2\.gz" [QSA]

    # Serve correct content types, and prevent mod_deflate double gzip.
    RewriteRule "\.css\.gz$" "-" [T=text/css,E=no-gzip:1]
    RewriteRule "\.js\.gz$"  "-" [T=text/javascript,E=no-gzip:1]


    <FilesMatch "(\.js\.gz|\.css\.gz)$">
      # Serve correct encoding type.
      Header append Content-Encoding gzip

      # Force proxies to cache gzipped &
      # non-gzipped css/js files separately.
      Header append Vary Accept-Encoding
    </FilesMatch>
</IfModule>

    The DeflateBufferSize directive specifies
    the size in bytes of the fragments that zlib should compress at one
    time. If the compressed response size is bigger than the one specified
    by this directive then httpd will switch to chunked encoding 
    (HTTP header Transfer-Encoding set to Chunked), with the
    side effect of not setting any Content-Length HTTP header. This is particularly 
    important when httpd works behind reverse caching proxies or when httpd is configured with 
    mod_cache and mod_cache_disk because
    HTTP responses without any Content-Length header might not be cached.

    The DeflateCompressionLevel directive specifies
        what level of compression should be used, the higher the value,
        the better the compression, but the more CPU time is required to
        achieve this.
    
    
    The value must between 1 (less compression) and 9 (more compression).

    DeflateFilterNote Directive
    

    

    Description:Places the compression ratio in a note for logging
    

    Syntax:DeflateFilterNote [type] notename
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_deflate
    

    
    
    The DeflateFilterNote directive
    specifies that a note about compression ratios should be attached
    to the request. The name of the note is the value specified for
    the directive. You can use that note for statistical purposes by
    adding the value to your access log.
    

    
    Example
    DeflateFilterNote ratio

LogFormat '"%r" %b (%{ratio}n) "%{User-agent}i"' deflate
CustomLog "logs/deflate_log" deflate
    

    

    
    If you want to extract more accurate values from your logs, you
    can use the type argument to specify the type of data
    left as a note for logging. type can be one of:
    

    
    
      
    Input
    
      
    Store the byte count of the filter's input stream in the note.
    

      
    Output
    
      
    Store the byte count of the filter's output stream in the note.
    

      
    Ratio
    
      
    Store the compression ratio (output/input * 100)
      in the note. This is the default, if the type argument
      is omitted.
    
    
    

    
    Thus you may log it this way:
    

    
    Accurate Logging
    DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio

LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
CustomLog "logs/deflate_log" deflate

    Description:Authorization based on file ownership
    

    Status:Extension
    

    Module Identifier:authz_owner_module
    

    Source File:mod_authz_owner.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module authorizes access to files by comparing the userid used
    for HTTP authentication (the web userid) with the file-system owner or
    group of the requested file. The supplied username and password
    must be already properly verified by an authentication module,
    such as mod_auth_basic or
    mod_auth_digest. mod_authz_owner
    recognizes two arguments for the Require directive, file-owner and
    file-group, as follows:
    

    
    
      
    file-owner
    
      
    The supplied web-username must match the system's name for the
      owner of the file being requested. That is, if the operating system
      says the requested file is owned by jones, then the
      username used to access it through the web must be jones
      as well.
    

      
    file-group
    
      
    The name of the system group that owns the file must be present
      in a group database, which is provided, for example, by mod_authz_groupfile or mod_authz_dbm,
      and the web-username must be a member of that group. For example, if
      the operating system says the requested file is owned by (system)
      group accounts, the group accounts must
      appear in the group database and the web-username used in the request
      must be a member of that group.
    
    
    

    
    Note
    
      
    If mod_authz_owner is used in order to authorize
      a resource that is not actually present in the filesystem
      (i.e. a virtual resource), it will deny the access.
    

      
    Particularly it will never authorize content negotiated
      "MultiViews" resources.

    Configuration Examples
    

    
    Require file-owner
    
      
    Consider a multi-user system running the Apache Web server, with
      each user having his or her own files in ~/public_html/private. Assuming that there is a single
      AuthDBMUserFile database
      that lists all of their web-usernames, and that these usernames match
      the system's usernames that actually own the files on the server, then
      the following stanza would allow only the user himself access to his
      own files. User jones would not be allowed to access
      files in /home/smith/public_html/private unless they
      were owned by jones instead of smith.
    

      
    <Directory "/home/*/public_html/private">
    AuthType Basic
    AuthName MyPrivateFiles
    AuthBasicProvider dbm
    AuthDBMUserFile "/usr/local/apache2/etc/.htdbm-all"
    Require file-owner
</Directory>
    

    

    
    Require file-group
    
      
    Consider a system similar to the one described above, but with
      some users that share their project files in
      ~/public_html/project-foo. The files are owned by the
      system group foo and there is a single AuthDBMGroupFile database that
      contains all of the web-usernames and their group membership,
      i.e. they must be at least member of a group named
      foo. So if jones and smith
      are both member of the group foo, then both will be
      authorized to access the project-foo directories of
      each other.
    

      
    <Directory "/home/*/public_html/project-foo">
    AuthType Basic
    AuthName "Project Foo Files"
    AuthBasicProvider dbm
    
    # combined user/group database
    AuthDBMUserFile  "/usr/local/apache2/etc/.htdbm-all"
    AuthDBMGroupFile "/usr/local/apache2/etc/.htdbm-all"
    
    Satisfy All
    Require file-group
</Directory>

    Apache Module mod_proxy_fcgi
    

    

    Available Languages:  en  |

    Description:FastCGI support module for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_fcgi_module
    

    Source File:mod_proxy_fcgi.c
    

    Compatibility:Available in version 2.3 and later
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the
    FastCGI protocol.
    

    
    Thus, in order to get the ability of handling the FastCGI
    protocol, mod_proxy and
    mod_proxy_fcgi have to be present in the server.
    

    
    Unlike mod_fcgid
    and mod_fastcgi,
    mod_proxy_fcgi has no provision for starting the
    application process; fcgistarter is provided
    (on some platforms) for that purpose. Alternatively, external launching
    or process management may be available in the FastCGI application
    framework in use.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.
    
    
    

    


    top
    

    

    Examples
    
    
    Remember, in order to make the following examples work, you have to
    enable mod_proxy and mod_proxy_fcgi.
    

    
    Single application instance
    ProxyPass "/myapp/" "fcgi://localhost:4000/"
    

    

    
     mod_proxy_fcgi disables connection reuse by
    default, so after a request has been completed the connection will NOT be
    held open by that httpd child process and won't be reused.  If the
    FastCGI application is able to handle concurrent connections
    from httpd, you can opt-in to connection reuse as shown in the following
    example:
    

    
    Single application instance, connection reuse (2.4.11 and later)
    ProxyPass "/myapp/" "fcgi://localhost:4000/" enablereuse=on
    

    

    
    Enable connection reuse to a FCGI backend like PHP-FPM
    
    
    Please keep in mind that PHP-FPM (at the time of writing, February 2018)
    uses a prefork model, namely each of its worker processes can handle one
    connection at the time.
     
    By default mod_proxy (configured with enablereuse=on)
    allows a connection pool of
    ThreadsPerChild connections to the
    backend for each httpd process when using a threaded mpm (like
    worker or event),
    so the following use cases should be taken into account:
    
    
      
      
    • Under HTTP/1.1 load it will likely cause the creation of up to
      MaxRequestWorkers
      connections to the FCGI backend.
      • 
      
    • Under HTTP/2 load, due to how mod_http2 is implemented,
      there are additional h2 worker threads that may force the creation of other
      backend connections. The overall count of connections in the pools may raise
      to more than MaxRequestWorkers.
      • 
    
    
    
    The maximum number of PHP-FPM worker processes needs to be configured wisely,
    since there is the chance that they will all end up "busy" handling idle
    persistent connections, without any room for new ones to be established,
    and the end user experience will be a pile of HTTP request timeouts.
    
    
    

    
     The following example passes the request URI as a filesystem
    path for the PHP-FPM daemon to run. The request URL is implicitly added
    to the 2nd parameter. The hostname and port following fcgi:// are where
    PHP-FPM is listening.  Connection pooling/reuse is enabled.
    
    
    PHP-FPM
    ProxyPassMatch "^/myapp/.*\.php(/.*)?$" "fcgi://localhost:9000/var/www/" enablereuse=on
    

    

    
     The following example passes the request URI as a filesystem
    path for the PHP-FPM daemon to run. In this case, PHP-FPM is listening on
    a unix domain socket (UDS).  Requires 2.4.9 or later. With this syntax,
    the hostname and optional port following fcgi:// are ignored.
    
    
    PHP-FPM with UDS
    ProxyPassMatch "^/(.*\.php(/.*)?)$" "unix:/var/run/php5-fpm.sock|fcgi://localhost/var/www/"
    

    

    
    The balanced gateway needs mod_proxy_balancer and
    at least one load balancer algorithm module, such as
    mod_lbmethod_byrequests, in addition to the proxy
    modules listed above.  mod_lbmethod_byrequests is the
    default, and will be used for this example configuration.

    ProxyPass "/myapp/" "balancer://myappcluster/"
<Proxy "balancer://myappcluster/">
    BalancerMember "fcgi://localhost:4000"
    BalancerMember "fcgi://localhost:4001"
</Proxy>
    

    

      
    You can also force a request to be handled as a reverse-proxy
        request, by creating a suitable Handler pass-through. The example
        configuration below will pass all requests for PHP scripts to the
        specified FastCGI server using reverse proxy.
        This feature is available in Apache HTTP Server 2.4.10 and later. For performance
       reasons, you will want to define a worker
       representing the same fcgi:// backend. The benefit of this form is that it
       allows the normal mapping of URI to filename to occur in the server, and the
       local filesystem result is passed to the backend.  When FastCGI is
       configured this way, the server can calculate the most accurate
       PATH_INFO.
      
    
    
    Proxy via Handler
    <FilesMatch "\.php$">
    # Note: The only part that varies is /path/to/app.sock
    SetHandler  "proxy:unix:/path/to/app.sock|fcgi://localhost/"
</FilesMatch>

# Define a matching worker.
# The part that is matched to the SetHandler is the part that
# follows the pipe. If you need to distinguish, "localhost; can
# be anything unique.
<Proxy "fcgi://localhost/" enablereuse=on max=10>
</Proxy>

<FilesMatch ...>
    SetHandler  "proxy:fcgi://localhost:9000"
</FilesMatch>

<FilesMatch ...>
    SetHandler  "proxy:balancer://myappcluster/"
</FilesMatch>

    Environment Variables
    
    
    In addition to the configuration directives that control the
    behaviour of mod_proxy, there are a number of
    environment variables that control the FCGI protocol
    provider:
    
    
    
        
    proxy-fcgi-pathinfo
    
        
    When configured via ProxyPass or  ProxyPassMatch, mod_proxy_fcgi will not
        set the PATH_INFO environment variable. This allows
        the backend FCGI server to correctly determine SCRIPT_NAME
        and Script-URI and be compliant with RFC 3875 section 3.3.
        If instead you need mod_proxy_fcgi to generate
        a "best guess" for PATH_INFO, set this env-var.
        This is a workaround for a bug in some FCGI implementations.  This
        variable can be set to multiple values to tweak at how the best guess
        is chosen (In 2.4.11 and later only):
        
    
          
    first-dot
    
          
    PATH_INFO is split from the slash following the
              first "." in the URL.
    
          
    last-dot
    
          
    PATH_INFO is split from the slash following the
              last "." in the URL.
    
          
    full
    
          
    PATH_INFO is calculated by an attempt to map the URL to the
              local filesystem.
    
          
    unescape
    
          
    PATH_INFO is the path component of the URL, unescaped /
              decoded.
    
          
    any other value
    
          
    PATH_INFO is the same as the path component of the URL.
              Originally, this was the only proxy-fcgi-pathinfo option.

    ProxyFCGIBackendType Directive
    

    

    Description:Specify the type of backend FastCGI application
    

    Syntax:ProxyFCGIBackendType FPM|GENERIC
    

    Default:ProxyFCGIBackendType FPM
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_proxy_fcgi
    

    Compatibility:Available in version 2.4.26 and later
    

    

    This directive allows the type of backend FastCGI application to be
specified. Some FastCGI servers, such as PHP-FPM,  use historical quirks of
environment variables to identify the type of proxy server being used.  Set
this directive to "GENERIC" if your non PHP-FPM application has trouble
interpreting environment variables such as SCRIPT_FILENAME or PATH_TRANSLATED
as set by the server.
    


    One example of values that change based on the setting of this directive is
SCRIPT_FILENAME. When using mod_proxy_fcgi historically,
SCRIPT_FILENAME was prefixed with the string "proxy:fcgi://". This variable is
what some generic FastCGI applications would read as their script input, but
PHP-FPM would strip the prefix then remember it was talking to Apache.  In
2.4.21 through 2.4.25, this prefix was automatically stripped by the server,
breaking the ability of PHP-FPM to detect and interoperate with Apache in some
scenarios.

    ProxyFCGISetEnvIf Directive
    

    

    Description:Allow variables sent to FastCGI servers to be fixed up
    

    Syntax:ProxyFCGISetEnvIf conditional-expression
    [!]environment-variable-name
    [value-expression]
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_proxy_fcgi
    

    Compatibility:Available in version 2.4.26 and later
    

    

    Just before passing a request to the configured FastCGI server, the core of
the web server sets a number of environment variables based on details of the
current request. FastCGI programs often uses these environment variables
as inputs that determine what underlying scripts they will process, or what
output they directly produce.
    

    Examples of noteworthy environment variables are:
    

      
  
    • SCRIPT_NAME
      • 
  
    • SCRIPT_FILENAME
      • 
  
    • REQUEST_URI
      • 
  
    • PATH_INFO
      • 
  
    • PATH_TRANSLATED
      • 

    


    This directive allows the environment variables above, or any others of
interest, to be overridden.  This directive is evaluated after the initial
values for these variables are set, so they can be used as input into both
the condition expressions and value expressions.
    

    Parameter syntax:
    

    

    conditional-expression
    

    Specifies an expression that controls whether the environment variable that
   follows will be modified.  For information on the expression syntax, see
   the examples that follow or the full specification at the
   ap_expr documentation.
   
    

    environment-variable-name
    

     Specifies the CGI environment variable to change,
   such as PATH_INFO. If preceded by an exclamation point, the variable 
   will be unset.
    

    value-expression
    

    Specifies the replacement value for the preceding environment variable.
   Backreferences, such as "$1", can be included from regular expression
   captures in conditional-expression. If omitted, the variable is
   set (or overridden) to an empty string — but see the Note below.
    

    


    # A basic, unconditional override
ProxyFCGISetEnvIf "true" PATH_INFO "/example"

# Use an environment variable in the value
ProxyFCGISetEnvIf "true" PATH_INFO "%{reqenv:SCRIPT_NAME}"

# Use captures in the conditions and backreferences in the replacement
ProxyFCGISetEnvIf "reqenv('PATH_TRANSLATED') =~ m|(/.*prefix)(\d+)(.*)|" PATH_TRANSLATED "$1$3"
    

    


    Note: Unset vs. Empty
    
  The following will unset VARIABLE, preventing it from being sent
  to the FastCGI server:

    
    ProxyFCGISetEnvIf true !VARIABLE
    


  Whereas the following will erase any existing value of
  VARIABLE (by setting it to the empty string), but the empty
  VARIABLE will still be sent to the server:

    
    ProxyFCGISetEnvIf true VARIABLE
    


  The CGI/1.1 specification
  does not
  distinguish between a variable with an empty value and a variable that
  does not exist. However, many CGI and FastCGI implementations distinguish (or
  allow scripts to distinguish) between the two. The choice of which to use is
  dependent upon your implementation and your reason for modifying the variable.

    Serveur HTTP Apache Version 2.4

    Module Apache mod_authz_dbm
    

    

    Langues Disponibles:  en  |
 fr  |
 ko 
    

    

    Description:Autorisation basée sur les groupes à l'aide de fichiers
DBM
    

    Statut:Extension
    

    Identificateur de Module:authz_dbm_module
    

    Fichier Source:mod_authz_dbm.c
    

    Compatibilité:Disponible depuis les versions 2.1 et supérieures
d'Apache
    

    Sommaire
    

    
    Ce module permet d'autoriser ou d'interdire l'accès à certaines
    zones du site web aux utilisateurs authentifiés en fonction de leur
    appartenance à un groupe spécifié. Le module
    mod_authz_groupfile fournit une fonctionnalité
    similaire.
    

    


    top
    

    

    The Require Directives
    

    
    Les directives Require d'Apache permettent,
    au cours de la phase d'autorisation, de s'assurer qu'un utilisateur
    est bien autorisé à accéder à une ressource.  mod_authz_dbm ajoute
    les types d'autorisation dbm-group et dbm-file-group.
    

    
    A partir de la version 2.4.8, les directives require DBM
    supportent les expressions.
    


    Require dbm-group
    

    
    Cette directive permet de spécifier à quel groupe un utilisateur
    doit appartenir pour obtenir l'autorisation d'accès.
    

    
    Require dbm-group admin
    





    Require dbm-file-group
    

    
    Lorsque cette directive est définie, l'utilisateur doit
    appartenir au groupe du fichier pour pouvoir y accéder.
    

    
    Require dbm-file-group
    





    top
    

    

    Exemple d'utilisation
    


    Notez que si vous utilisez mod_authz_dbm, le mot-clé pour les
groupes d'authentification qui était auparavant group est
maintenant dbm-group :

    

    <Directory "/foo/bar">
  AuthType Basic 
  AuthName "Secure Area"
  AuthBasicProvider dbm 
  AuthDBMUserFile "site/data/users"
  AuthDBMGroupFile "site/data/users" 
  Require dbm-group admin 
</Directory>
    


    

    top
    

    Directive AuthDBMGroupFile
    

    

    Description:Définit le nom du fichier de base de données contenant la
liste des groupes d'utilisateurs permettant de définir les
autorisations des utilisateurs
    

    Syntaxe:AuthDBMGroupFile chemin-fichier
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_authz_dbm
    

    
    
    La directive AuthDBMGroupFile sert à
    définir le nom d'un fichier DBM contenant la liste des groupes
    d'utilisateurs. Les utilisateurs peuvent dès lors se voir autoriser ou
    refuser leurs accès selon l'appartenance à tel ou tel groupe.
    chemin-fichier est le chemin absolu du
    fichier de groupes.
    

    
    La clé du fichier de groupes est le nom d'utilisateur. La valeur
    de chaque clé est la liste des groupes, séparés par des virgules,
    auxquels l'utilisateur appartient. Cette liste ne doit comporter
    ni espace, ni caractère ':'.
    

    
    Sécurité
    
      
    Le fichier spécifié par la directive
AuthDBMGroupFile doit être situé en dehors de
l'arborescence des documents du serveur web. Ne le placez
surtout pas dans le répertoire qu'il protège, faute
de quoi, les clients pourraient le télécharger, en l'abscence de
protection supplémentaire.
    
    
    

    
    Utilisation combinée de fichiers DBM de groupes et de mots de
    passe : dans certains cas, il est plus simple de gérer une seule
    base de données contenant les groupes et mots de passe de chaque
    utilisateur. L'écriture de programmes de support en est ainsi
    simplifiée car ils n'ont plus qu'un seul fichier DBM à gérer et
    à verrouiller. Pour ce faire, on attribue le même nom de fichier
    DBM aux fichiers de groupes et de mots de passe :
    

    
    AuthDBMGroupFile "/www/userbase"
AuthDBMUserFile "/www/userbase"
    


    
    La clé du fichier DBM unique est le nom d'utilisateur. La
    valeur associée à la clé contient :
    

    
    
      Mot de passe chiffré : Liste de groupes [ : (ignoré) ]
    
    

    
    La partie mot de passe contient comme d'habitude le mot de
    passe chiffré. Viennent ensuite le caractère ':' et la liste des
    groupes séparés par des virgules. Il est possible d'ajouter
    d'autres données en fin de ligne après un autre caractère ':',
    mais elles seront ignorées par le module d'autorisation. Il s'agit
    du format utilisé par www.telescope.org pour sa base de données
    combinée groupes et mots de passe.

    Directive AuthzDBMType
    

    

    Description:Définit le type de fichier de base de données contenant
la liste des groupes d'utilisateurs
    

    Syntaxe:AuthzDBMType default|SDBM|GDBM|NDBM|DB
    

    Défaut:AuthzDBMType default
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_authz_dbm
    

    
    
    Définit le type de fichier de base de données contenant la
    liste des groupes d'utilisateurs. Le type de base de données par
    défaut est déterminé à la compilation. Les autres types de bases
    de données disponibles dépendent aussi de la
    configuration de la
    compilation.
    

    
    Quel que soit le programme que vous utilisez pour créer votre
    fichier de groupes, il est impératif que celui-ci soit configuré
    pour utiliser le même type de base de données.

    Module Apache mod_sed
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Filtre les contenus en entrée (requêtes) et en sortie
(réponses) en utilisant la syntaxe de sed
    

    Statut:
    

    Identificateur de Module:sed_module
    

    Fichier Source:mod_sed.c sed0.c sed1.c regexp.c regexp.h sed.h
    

    Compatibilité:Disponible depuis la version 2.3 d'Apache
    

    Sommaire
    


    mod_sed est un filtre de contenu "in-process". Le
filtre mod_sed fournit les commandes d'édition de
sed implémentées par le programme sed de
Solaris 10 comme décrit dans la page de
manuel. Cependant, à la différence de sed,
mod_sed ne reçoit pas de données sur son entrée
standard. Au lieu de cela, le filtre agit sur les données échangées
entre le client et le serveur. mod_sed peut être
utilisé comme filtre en entrée ou en sortie. mod_sed
est un filtre de contenu, ce qui signifie qu'on ne peut pas l'utiliser
pour modifier les en-têtes http du client ou du serveur.

    

    
Le filtre en sortie mod_sed accepte un tronçon de
données, exécute le script sed sur ces données, puis génère
une sortie qui est transmise au filtre suivant dans la chaîne.

    


    
Le filtre en entrée mod_sed reçoit des données en
provenance du filtre suivant dans la chaîne, exécute les scripts
sed, et renvoie les données générées au filtre appelant
dans la chaîne de filtrage.

    


    
Les filtres en entrée ou en sortie ne traitent les données que si des
caractères newline sont détectés dans le contenu à filtrer. A la fin des
données, ce qui reste est traité comme la dernière ligne.

    


    


    top
    

    

    Exemple de configuration
    
    
    Ajout d'un filtre en sortie
    # Dans l'exemple suivant, le filtre sed va remplacer la chaîne
	 # "monday" par "MON" et la chaîne "sunday" par "SUN" dans les
	 # documents html avant de les envoyer au client.
<Directory "/var/www/docs/sed"> 
    AddOutputFilter Sed html 
    OutputSed "s/monday/MON/g" 
    OutputSed "s/sunday/SUN/g" 
</Directory>
    

    

    
    Ajout d'un filtre en entrée
             # Dans l'exemple suivant, le filtre sed va remplacer la chaîne
	 # "monday" par "MON" et la chaîne "sunday" par "SUN" dans les
	 # données POST envoyées à PHP.
        <Directory "/var/www/docs/sed"> 
    AddInputFilter Sed php 
    InputSed "s/monday/MON/g" 
    InputSed "s/sunday/SUN/g"

    Ce module permet de contrôler les variables d'environnement
    internes utilisées par divers modules du serveur HTTP Apache. Ces
    variables sont aussi accessibles aux scripts CGI en tant que
    variables d'environnement système natives, et disponibles dans les
    pages SSI. Les variables d'environnement peuvent
    être transmises depuis le shell qui a lancé le processus
    httpd. Elles peuvent également être définies ou
    supprimées au cours du processus de configuration.

    Module:mod_env
    

    
    
    Cette directive permet de spécifier quelles variables
    d'environnement système natives doivent être disponibles en tant que
    variables d'environnement internes pour les modules du serveur HTTP
    Apache, et propagées vers les scripts CGI et les pages SSI. Leurs
    valeurs sont issues de l'environnement natif de l'OS associé au
    shell qui a invoqué le processus httpd.

    Statut:Base
    

    Module:mod_env
    

    
    
    Définit une variable d'environnement interne, cette dernière étant
    ensuite disponible pour les modules du serveur HTTP Apache et
    transmise aux scripts CGI et aux pages SSI.
    

    
    Exemple
    SetEnv SPECIAL_PATH /foo/bin
    

    

    
    Si l'argument valeur est absent, la variable est
    définie à la valeur d'une chaîne vide.
    

    
    Les variables d'environnement internes définies par cette
    directive le sont après l'exécution de la plupart des
    directives du traitement initial des requêtes, comme les contrôles
    d'accès et la mise en correspondance des URIs avec les noms de
    fichiers. Si la variable d'environnement est sensée intervenir au
    cours de cette phase initiale du traitement, par exemple pour la
    directive RewriteRule,
    vous devez plutôt utiliser la directive SetEnvIf pour définir cette
    variable.

    Description:Module multi-processus implémentant un serveur web hybride
multi-processus multi-thread
    

    Statut:MPM
    

    Identificateur de Module:mpm_worker_module
    

    Fichier Source:worker.c
    

    Sommaire
    

    
    Ce module multi-processus (MPM) implémente un serveur hybride
    multi-processus multi-thread. En utilisant les threads pour servir
    les requêtes, il peut en traiter un grand nombre tout en consommant
    moins de ressources qu'un serveur à base de processus. Cependant, il
    conserve une grande partie de la stabilité d'un serveur à base de
    processus en maintenant plusieurs processus disponibles, chacun de
    ces derniers possédant de nombreux threads.
    

    
    Les directives les plus importantes qui permettent de contrôler
    ce MPM sont ThreadsPerChild, qui définit le
    nombre de threads lancés par chaque processus enfant et MaxRequestWorkers, qui définit le nombre
    global maximum de threads qui peuvent être lancés.
    

    


    top
    

    

    Comment ça marche
    
    
    Un processus de contrôle unique (le parent) a pour tâche de
    lancer les processus enfants. Chaque processus enfant crée un nombre
    fixe de threads serveurs selon la valeur de la directive ThreadsPerChild, ainsi
    qu'un thread chargé d'attendre les connexions et de les passer à un
    thread serveur pour traitement au fur et à mesure de leur arrivée.
    

    
    Le serveur HTTP Apache essaie toujours de maintenir un jeu de
    threads serveurs
    inactifs ou en réserve, qui se tiennent prêts à traiter
    les requêtes entrantes. De cette façon, les clients n'ont pas besoin
    d'attendre la création d'un nouveau thread ou d'un nouveau processus
    pour que leurs requêtes puissent être traitées. Le nombre de
    processus lancés initialement est défini par la directive StartServers. En cours de
    fonctionnement, le serveur évalue le nombre total de threads inactifs
    dans tous les processus, et en crée ou en arrête de façon à
    maintenir ce nombre à l'intérieur des limites définies par les
    directives MinSpareThreads et MaxSpareThreads. Comme ce module
    s'auto-contrôle de manière efficace, on peut en général conserver
    les valeurs par défaut. Le nombre maximum de clients pouvant être
    servis simultanément (c'est à dire le nombre global maximum de
    threads pour tous les processus) est défini par la directive
    MaxRequestWorkers. Le nombre
    maximum de processus enfants actifs est défini par la valeur de la
    directive MaxRequestWorkers
    divisée par la valeur de la directive 
    ThreadsPerChild.
    

    
    Deux directives permettent de fixer des limites absolues pour le
    nombre de processus enfants actifs et le nombre de threads serveurs
    par processus enfant, et ne peuvent être modifiées qu'en
    arrêtant complètement le serveur et en le démarrant à nouveau.
    La valeur de la directive ServerLimit constitue une limite
    absolue pour le nombre de processus enfants actifs, et doit être
    supérieure ou égale à la valeur de la directive MaxRequestWorkers divisée par la valeur de
    la directive 
    ThreadsPerChild. La valeur de la directive ThreadLimit constitue une limite
    absolue pour le nombre de threads par processus enfant, et doit être
    supérieure ou égale à la valeur de la directive ThreadsPerChild.
    

    
    En plus du jeu de processus enfants actifs, il peut exister
    quelques processus enfants en cours d'arrêt, mais dont au moins un
    thread serveur est encore en train de traiter une connexion client
    existante. Il peut subsister en théorie jusqu'à MaxRequestWorkers processus en cours
    d'arrêt, bien qu'en réalité, ce nombre sera en général beaucoup plus
    petit. Ce comportement peut être évité en désactivant l'arrêt de
    processus enfants individuels de la manière suivante :
    

    

    
    Voici un exemple typique de configuration du contrôle
    processus-thread pour le MPM worker :
    

    
    ServerLimit         16
StartServers         2
MaxRequestWorkers  150
MinSpareThreads     25
MaxSpareThreads     75
ThreadsPerChild     25
    


    
    Alors que le processus parent est en général démarré en tant que
    root sous Unix afin de se mettre en écoute du port 80,
    les processus enfants et les threads sont lancés par le serveur sous un
    utilisateur avec privilèges restreints. On peut utiliser les
    directives User et Group pour définir les privilèges
    des processus enfants. Les processus enfants doivent pouvoir être en
    mesure de lire tous les contenus destinés à être servis, mais
    doivent avoir des privilèges aussi bas que possible. De plus, ces
    directives définissent également les privilèges dont vont hériter les
    scripts CGI (sauf si on utilise suexec).
    

    
    La directive MaxConnectionsPerChild permet de
    définir la fréquence à laquelle le serveur recycle ses processus en
    arrêtant les plus anciens et en en lançant de nouveaux.
    

    
    Ce module MPM utilise le mutex mpm-accept pour
    sérialiser l'accès aux connexions entrantes lorsqu'un problème
    d'afflux de requêtes peut survenir (en général, lorsqu'il y a
    plusieurs sockets en écoute). Les différents aspects de
    l'implémentation de ce mutex peuvent être configurés via la
    directive Mutex. Vous
    trouverez des informations plus détaillées à propos de ce mutex dans
    la documentation sur les conseils en matière de
    performances.

    Module Apache mod_systemd
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Fournit un support amélioré pour l'intégration de systemd
    

    Statut:Extension
    

    Identificateur de Module:systemd_module
    

    Fichier Source:mod_systemd.c
    

    Sommaire
    

    
    Ce module implémente le support de l'intégration de systemd. Il
    permet d'utiliser httpd en temps que service avec le paramètre de
    systemd Type=notify (voir la page de manuel
    systemd.service(5)
    pour plus de détails). Le module est activé s'il est chargé.
    

    
    Exemple basique d'unité de service systemd (à étoffer pour un système en
    production)
    [Unit]
Description=The Apache HTTP Server
After=network.target

[Service]
Type=notify
ExecStart=/usr/local/apache2/bin/httpd -D FOREGROUND -k start
ExecReload=/usr/local/apache2/bin/httpd -k graceful
KillMode=mixed

[Install]
WantedBy=multi-user.target
    

   
    Si vous utilisez ExecStop et/ou KillMode, vous
   devez prêter une attention particulière à leur configuration pour ce service.
   Si elle est présente, une commande ExecStop doit être une
   operation synchrone qui se termine elle-même en même temps que le
   démon. Cette condition n'est pas satisfaite si vous exécutez la commande
   httpd -k stop de manière asynchrone, car elle initie
   l'arrêt du démon. L'exemple ci-dessus utilise KillMode=mixed
   afin que systemd envoie SIGTERM au processus parent (et
   seulement à ce dernier) pour lui indiquer qu'il doit s'arrêter. Les processus
   encore en cours d'exécution après un temps égal à TimeoutStopSec
   recevront alors le signal SIGKILL. Voir systemd.kill(5)
   pour plus d'informations.
    
    
   
    Ce module ne fournit pas le support de l'activation du socket Systemd.
    

    
    ExtendedStatus est activé par défaut
    si le module est chargé. Si ExtendedStatus n'est pas explicitement désactivé
    dans le fichier de configuration, les statistiques à propos de la charge et
    des requêtes pendant l'exécution apparaîtront dans la sortie de la commande
    systemctl status.
    

    

    Support Apache!

    Module Apache mod_imagemap
    

    

    Langues Disponibles:  en  |

    Description:Traitement des cartes des zones interactives d'une image
(imagemaps) au niveau du serveur
    

    Statut:Base
    

    Identificateur de Module:imagemap_module
    

    Fichier Source:mod_imagemap.c
    

    Sommaire
    

    
    Ce module traite les fichiers .map, et remplace
    ainsi la fonctionnalité du programme CGI imagemap. Tout
    répertoire ou type de document configuré pour utiliser le
    gestionnaire imap-file (à l'aide des directives
    AddHandler ou SetHandler), sera traité par ce
    module.
    

    
    La directive suivante confère aux fichiers possèdant l'extension
    .map le statut de fichiers imagemap :
    

    
    AddHandler imap-file map
    


    
    Notez que la syntaxe suivante reste encore supportée :
    

    
    AddType application/x-httpd-imap map
    


    
    Cependant, nous essayons d'abandonner progressivement les "types
    MIME magiques", et cette syntaxe est sur le point de devenir
    obsolète.

    Nouvelles fonctionnalités
    

    
    Le module imagemap propose quelques nouvelles fonctionnalités qui
    n'étaient pas disponibles avec les programmes imagemap précédemment
    distribués.
    

    
      
      
    • Références d'URLs relatives à l'information contenue dans
      l'en-tête Referer: .
      • 

      
    • Assignement <base> par défaut via la
      nouvelle directive base.
      • 

      
    • Fichier imagemap.conf non requis.
      • 

      
    • Références à des points.
      • 

      
    • Génération configurable de menus d'images interactives.
      • 
    
    

    top
    

    

    Fichier imagemap
    

    
    Les lignes d'un fichier imagemap peuvent se présenter sous
    plusieurs formats :
    

    
    
      directive valeur [x,y ...]
    
      directive valeur "Texte de menu" [x,y
      ...]
    
      directive valeur x,y ... "Texte de menu"
    
    

    
    Les directives sont base, default,
    poly, circle, rect, ou
    point. valeur est une URL absolue ou relative, ou une
    des valeurs spéciales énumérées ci-dessous. Les coordonnées sont des
    paires x,y séparées par des
    espaces. Le texte entre guillemets est le texte du lien si un menu
    imagemap est généré. Les lignes commençant par '#' sont des
    commentaires.
    

    
    Directives d'un fichier
    imagemap
    
      
    Les directives autorisées dans un fichier imagemap sont au
      nombre de six. Elles peuvent se trouver à n'importe quelle
      position dans le fichier, mais sont traitées dans l'ordre selon
      lequel elles sont enregistrées dans le fichier imagemap.
    

      
    
      
    Directive base
    

      
    Elle a le même effet que <base
      href="valeur">. Les URLs non absolues du
      fichier imagemap sont considérées comme relatives à cette valeur.
      La directive base l'emporte sur une directive
      ImapBase définie dans
      un fichier .htaccess ou dans le fichier de
      configuration du serveur. En l'absence de directive de
      configuration ImapBase, la valeur par
      défaut de base est
      http://nom_serveur/.
    
      
    base_uri est un synonyme de base.
      Notez que la présence ou l'absence d'un slash de fin dans l'URL
      est importante.
    

      
    Directive default
    

      
    La décision à prendre si les coordonnées fournies ne
      correspondent à aucune des directives poly,
      circle, ou rect, et si aucune directive
      point n'est présente. En l'absence de définition
      d'une directive de configuration ImapDefault, la valeur par défaut est
      nocontent et provoque l'envoi d'un code de statut
      204 No Content. Le client verra toujours la même
      page s'afficher.
    

      
    Directive poly
    

      
    Accepte comme arguments trois à cent points, et est actionnée
      si les coordonnées sélectionnées par l'utilisateur tombent dans le
      polygone défini par ces points.
    

      
    Directive circle
    

      
    Accepte comme arguments les coordonnées du centre d'un cercle
      et celles d'un point de ce cercle. Elle est actionnée si les
      coordonnées sélectionnées par l'utilisateur tombent dans ce
      cercle.
    

      
    Directive rect
    

      
    Accepte comme arguments les coordonnées des sommets de deux
      angles opposés d'un rectangle. Elle est actionnée si les
      coordonnées sélectionnées par l'utilisateur tombent dans ce
      rectangle.
    

      
    Directive point
    

      
    Elle n'accepte qu'un seul point comme argument. Si aucune
      autre directive ne correspond, c'est la directive
      dont le point spécifié est le plus près du point sélectionné par
      l'utilisateur qui est actionnée. Notez que la directive
      default ne sera pas suivie si une directive
      point est présente et si des coordonnées valides sont
      fournies.
    
      
    
    

    
    Valeurs
    

      
    Les valeurs passées aux directives peuvent contenir :
    

      
    
      
    une URL
    

      
    L'URL peut être absolue ou relative. Les URLs relatives
      peuvent contenir '..' et seront considérées comme relatives à la
      valeur de base.
    
      
    base en lui-même, ne sera pas résolu en fonction
      de la valeur courante. Cependant, une directive base
      mailto: fonctionnera correctement.
    

      
    map
    

      
    Équivalent à l'URL du fichier imagemap lui-même. Aucune
      coordonnée n'est spécifiée, et un menu sera donc généré, à moins
      qu'une directive ImapMenu n'ait été définie à
      none.
    

      
    menu
    
      
    Équivalent à map.
    

      
    referer
    

      
    Équivalent à l'URL du document référant. La valeur par défaut
      est http://nom_serveur/ si aucun en-tête
      Referer: n'est présent.
    

      
    nocontent
    

      
    Envoie un code de statut 204 No Content,
      indiquant au client qu'il doit continuer à afficher la même page.
      Valide pour toutes les directives, sauf base.
    

      
    error
    

      
    Envoie un code de statut d'échec 500 Server
      Error. Valide pour toutes les directives, sauf
      base, mais n'a de sens qu'avec la directive
      default.
    
      
    
    

    
    Coordonnées
    

      
    
      
    0,0 200,200
    

      
    Une coordonnée se compose de deux valeurs,  x et
      y, séparées par une virgule. Les coordonnées sont
      séparées entre elles par des espaces. Pour s'adapter à la manière
      dont Lynx traite les images interactives, la sélection par un
      utilisateur de la coordonnée 0,0 a le même effet que
      si aucune coordonnée n'a été sélectionnée.
    
      
    

    

    
    Texte entre
    guillemets
    

      
    
      
    "Texte du menu"
    

      
    Après la valeur ou les coordonnées, la ligne peut
      éventuellement contenir un texte entre guillemets. Cette chaîne
      constitue le texte du lien si un menu est généré :
    

      
    
        <a href="http://example.com/">Texte de
	menu</a>
      
    

      
    Si aucun texte entre guillemets n'est présent, le texte sera
      constitué du nom du lien :
    

      
    
        <a href="http://example.com/">http://example.com</a>
      
    

      
    Si vous voulez insérer des guillemets dans le texte, vous devez
      les inscrire sous la forme &quot;.
    
      
    

    

    top
    

    

    Exemple de fichier imagemap
    

    
    
      #Les commentaires sont affichés dans un menu 'formaté' ou
      #'semi-formaté'.
    
      #Et peuvent contenir des balises html. <hr>
    
      base referer
    
      poly map "Puis-je avoir un menu, s'il vous plait ?" 0,0 0,10 10,10 10,0

    Statut:Base
    

    Module:mod_imagemap
    

    
    
    La directive ImapBase permet de définir la
    valeur par défaut de la directive base des fichiers
    imagemap. Sa valeur est écrasée par la présence éventuelle d'une
    directive base dans le fichier imagemap. Si cette
    directive est absente, la valeur par défaut de la directive
    base est
    http://nom_serveur/.

    Directive ImapDefault
    

    

    Description:Action à entreprendre par défaut lorsqu'un fichier imagemap
est invoqué avec des coordonnées qui ne correspondent à aucune
cible
    

    Syntaxe:ImapDefault error|nocontent|map|referer|URL
    

    Défaut:ImapDefault nocontent
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_imagemap
    

    
    
    La directive ImapDefault permet de définir
    la valeur par défaut de la directive default utilisée
    dans les fichiers imagemap. Sa valeur est écrasée par la présence
    éventuelle d'une directive default dans le fichier
    imagemap. Si cette directive est absente, l'action associée à
    default est nocontent, ce qui implique
    l'envoi d'un code de statut 204 No Content au client.
    Dans ce cas, le client doit continuer à afficher la même page.
    


    

    top
    

    Directive ImapMenu
    

    

    Description:Action à entreprendre si aucune coordonnée n'est fournie
lorsqu'on invoque un fichier imagemap
    

    Syntaxe:ImapMenu none|formatted|semiformatted|unformatted
    

    Défaut:ImapMenu formatted
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_imagemap
    

    
    
    La directive ImapMenu permet de spécifier
    l'action à entreprendre lorsqu'un fichier imagemap est invoqué sans
    coordonnées valides.
    

    
    
      
    none
    
      
    Si l'argument d'ImapMenu est none, aucun menu
      n'est généré, et l'action default est effectuée.
    

      
    formatted
    
      
    Le menu formatted est le menu le plus simple. Les
      commentaires du fichier imagemap sont ignorés. Un en-tête de
      niveau un est affiché, puis un séparateur horizontal, puis chacun
      des liens sur une ligne séparée. L'aspect du menu est similaire à
      celui d'un listing de répertoire.
    

      
    semiformatted
    
      
    Dans le menu semiformatted, les commentaires sont
      affichés au moment où ils apparaissent dans le fichier imagemap.
      Les lignes vides sont interprètées comme des lignes de séparation
      HTML. Aucun en-tête ni séparateur horizontal n'est affiché. À part
      ces différences, le menu semiformatted est identique
      au menu formatted.
    

      
    unformatted
    
      
    Les commentaires sont affichés et les lignes vides sont
      ignorées. N'est affiché que ce qui apparait dans le fichier
      imagemap. Toutes les lignes de séparation HTML et les
      en-têtes doivent être inclus en tant que commentaires dans le
      fichier imagemap. Cela vous procure une grande souplesse pour
      définir l'apparence de vos menus, mais vous oblige à rédiger vos
      fichiers imagemap en HTML, et non en texte plat.

    説明:リクエスト毎に入力バイト数と出力バイト数とをロギング
    

    ステータス:Extension
    

    モジュール識別子:logio_module
    

    ソースファイル:mod_logio.c
    

    概要
    


    
    このモジュールはリクエストごとに受け取ったバイト数と
    送信したバイト数のロギングを行なう機能を提供します。
    記録される数字はリクエストのヘッダとレスポンスの本体を
    反映した、実際にネットワークで受け取ったバイト値です。
    入力では SSL/TLS の前に、出力では SSL/TLS の後に数えるので、
    数字は暗号による変化も正しく反映したものになります。
    

    
    このモジュールの使用には mod_log_config モジュールが
    必要です。
    


    


    top
    

    

    カスタムログ書式
    


    
    このモジュールは新しいロギング用ディレクティブを加えます。
    リクエスト自身の特徴はフォーマット文字列に、以下の様に置換される
     "%" ディレクティブを
    入れることでログ収集されます:
    

    
    フォーマット文字列
        説明
    

    %...I
        リクエストとヘッダを含む、受け取ったバイト数。
        0 にはならない。
    

    %...O
        ヘッダを含む、送信したバイト数。0 にはならない。
    

    

    
    通常、この機能は以下の様に使用されます:
    

    
    
      
    結合 I/O ログ書式:
    
      
    "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
      \"%{User-agent}i\" %I %O"

    説明:分散オーサリングとバージョン管理
(WebDAV) 機能
    

    ステータス:Extension
    

    モジュール識別子:dav_module
    

    ソースファイル:mod_dav.c
    

    概要
    

    
    このモジュールはクラス 1 とクラス 2 の
    WebDAV
    ('ウェブベースの分散オーサリングとバージョン管理')
    機能を Apache に提供します。
    この HTTP プロトコルの拡張により、リモートのウェブサーバ上にある
    リソースやコレクションを
    作成、移動、複製、削除できるようになります。
    

    


    top
    

    

    Enabling WebDAV
    
    
    mod_dav を有効にするには、httpd.conf
    ファイル中のコンテナに次を加えます:
    

    
    Dav On
    


    
    これは DAV ファイルシステムプロバイダを有効にします。DAV
    ファイルシステムプロバイダは mod_dav_fs
    モジュールで実装されています。ですから、このモジュールはコンパイル時に
    サーバに組み込まれているか、あるいは
    LoadModule
    を使用して実行時にロードされている必要があります。
    
    
    
    さらに、DAV ロックデータベースの場所が
    DavLockDB ディレクティブを使って
    httd.conf ファイルのグローバルセクションに指定されている
    必要があります。
    

    
    DavLockDB /usr/local/apache2/var/DavLock
    


    
    ロックデータベースファイルのあるディレクトリは Apache が実行されている
    User と Group に書き込み権限がある必要があります。
    

    
    <Limit>
    節を <Location>
    ディレクティブ内部に追加して、DAV が有効な場所への
    アクセスを制限することもできます。DAV クライアントが
    一度のリクエストで送信できる最大バイト数を指定したいときは、
    LimitXMLRequestBody
    ディレクティブを使用する必要があります。「通常の」
    LimitRequestBody
    ディレクティブは DAV リクエストに対しては効力を持ちません。
    

    
    完全な例
    DavLockDB /usr/local/apache2/var/DavLock

<Directory /usr/local/apache2/htdocs/foo>
    Require all granted
    Dav On

    AuthType Basic
    AuthName DAV
    AuthUserFile user.passwd

    <LimitExcept GET POST OPTIONS>
        Require user admin
    </LimitExcept>
</Directory>
    

    


    top
    

    

    セキュリティの問題
    

    
    DAV のアクセスメソッドは遠隔クライアントがサーバのファイルを
    操作することを可能にしますので、 mod_dav を使用する
    前に、サーバが安全であることを特に注意して確認しなければなりません。
    

    
    サーバ上の DAV が使用可能になっている場所はすべて認証で保護してください。
    HTTP 基本認証の使用は推奨できません。少なくとも 
    mod_auth_digest モジュールで提供される HTTP 
    ダイジェスト認証を用いるべきです。WebDAV クライアントのほとんどは
    この認証方法に対応しています。代わりに、SSL が
    有効なコネクションを通した基本認証を使うこともできます。
    

    
    mod_dav がファイルを操作できるようにするためには、
    管理下のディレクトリとファイルとに Apache が実行されている User と Group で書き込み可能である必要があります。
    新しく作成されるファイルもこの User
    と Group に所有される
    ことになります。この理由から、そのアカウントへのアクセスを制御することは
    重要です。DAV リポジトリは Apache 専用のものだとみなされています。
    Apache 以外の方法でファイルを修正すること (例えば FTP やファイルシステム
    用のツールなどを使って) は許可されていません。
    

    
    mod_dav はいろいろな種類のサービス拒否攻撃にさらされる
    かもしれません。LimitXMLRequestBody ディレクティブを使うと
    大きな DAV リクエストを解析するときに消費されるメモリの量を制限することが
    できます。DavDepthInfinity ディレクティブは
    PROPFIND リクエストが巨大リポジトリで大量のメモリを消費するのを
    防ぐことができます。他のサービス拒否攻撃には単純に使用可能なディスク領域を
    多くの大きなファイルで埋めてしまうんものがあります。これを直接防ぐ方法は
    Apache にはありませんので、信用できないユーザに DAV アクセスを提供するのは
    避けた方が良いでしょう。
    

    top
    

    

    複雑な設定
    

    
    よくある要求に、mod_dav を使って動的なファイル
    (PHP スクリプト、CGI スクリプトなど) を操作したいというものがあります。
    これの実現は、GET リクエストはスクリプトの内容をダウンロードさせる
    代わりに、スクリプトを常に実行させてしまうので難しくなっています。
    これを回避する方法には、二つの違う URL を同じコンテンツにマップし、
    一つはスクリプトを実行させ、もう一つはダウンロードさせたり、DAV から
    操作されたりするように設定するというものがあります。
    


    Alias /phparea /home/gstein/php_files
Alias /php-source /home/gstein/php_files
<Location /php-source>
    Dav On
    ForceType text/plain
</Location>
    


    
    この設定により、http://example.com/phparea を PHP スクリプトの
    出力をアクセスするために使うことができ、
    http://example.com/php-source を DAV クライアントによる
    が操作のために使うことができます。
    

    

    top
    

    Dav ディレクティブ
    

    

    説明:WebDAV HTTP メソッドを有効にします
    

    構文:Dav On|Off|provider-name
    

    デフォルト:Dav Off
    

    コンテキスト:ディレクトリ
    

    ステータス:Extension
    

    モジュール:mod_dav
    

    
    
    与えられたコンテナで WebDAV HTTP メソッドが使えるようにするには
    次のようにします。
    

    
    <Location /foo>
    Dav On
</Location>
    


    
    On という指定は実際には mod_dav_fs
    で提供されているデフォルトのプロバイダ、filesystem
    へのエイリアスになっています。一度あるロケーションで DAV 
    を有効にした後は、そのサブロケーションで無効化することはできない
    ということに注意してください。完全な設定例は上記のセクション をご覧下さい。
    

    
    
      サーバのセキュリティが確保できるまで WebDAV を有効にしないでください。
      そうしなければ誰でもそのサーバでファイルを配布することができるように
      なってしまいます。
    
    


    

    top
    

    DavDepthInfinity ディレクティブ
    

    

    説明:PROPFIND, Depth: Infinity リクエストを許可します
    

    構文:DavDepthInfinity on|off
    

    デフォルト:DavDepthInfinity off
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ
    

    ステータス:Extension
    

    モジュール:mod_dav
    

    
    
    'Depth: Infinity' を含んでいる
    PROPFIND リクエストを処理できるようにするには、
    DavDepthInfinity
    ディレクティブを使います。このタイプのリクエストは
    denial-of-service アタックとなりうるので、
    デフォルトでは許可されていません。
    


    

    top
    

    DavMinTimeout ディレクティブ
    

    

    説明:サーバが DAV リソースのロックを維持する最小時間です。

    

    構文:DavMinTimeout seconds
    

    デフォルト:DavMinTimeout 0
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ
    

    ステータス:Extension
    

    モジュール:mod_dav
    

    
    
    クライアントが DAV リソースロックを要求した場合、
    ロックがサーバによって自動的に解除されるまでの時間を
    同時に指定することができます。この値は単なるリクエストであって、
    サーバはこれを無視することもできますし、
    任意の値をクライアントに通知することもできます。
    

    
    クライアントに戻すロックタイムアウトの最小時間を、
    秒で、指定するために DavMinTimeout
    ディレクティブを使います。
    マイクロソフトのウェブフォルダのデフォルトでは 120 秒ですが；
    ネットワークの遅延のせいでクライアントがロックを失うのを減らすために、
    DavMinTimeout を使って
    これをもっと大きな値 (例えば 600 秒) に上書きできます。
    

    
    例
    <Location /MSWord>
    DavMinTimeout 600
</Location>

    CoreDumpDirectory ディレクティブ
    

    

    説明:Apache がコアダンプする前に移動を試みるディレクトリ

    

    構文:CoreDumpDirectory directory
    

    デフォルト:デフォルトの設定は説明文を読んでください
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_winnt, perchild, prefork, threadpool, worker
    

    
    
    Apache がコアダンプする前に移動を試みるディレクトリを制御します。
    デフォルト値は ServerRoot
    ディレクトリですが、このディレクトリはサーバの実行されているユーザ権限で
    書き込み可能であるべきではないので、通常はコアダンプは書き込まれません。
    デバッグのためにコアダンプが必要であれば、
    このディレクティブを使って他の位置にコアダンプを書き出すようにできます。
    

    
    Linux でのコアダンプ
    
      
    Apache が root として起動されて、別のユーザの権限に以降した場合は
      Linux のカーネルはディレクトリがプロセスの権限で書き込み可能な場合でさえも
      コアダンプを無効にします。Apache (2.0.46 以降) は
      Linux 2.4 以降ではコアダンプを行なうように再指定しますが、それは
      CoreDumpDirectory を明示的に設定したときに
      限ります。

    EnableExceptionHook ディレクティブ
    

    

    説明:クラッシュの後に例外ハンドラを実行するフックを有効にする
    

    構文:EnableExceptionHook On|Off
    

    デフォルト:EnableExceptionHook Off
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:leader, perchild, prefork, threadpool, worker
    

    互換性:2.0.49 以降
    

    
    
    安全上の理由から、--enable-exception-hook configure
    オプションを有効にした場合にのみ、このディレクティブを利用できます。
    外部モジュールをプラグインして、子がクラッシュした後に何か実行できるような
    フックを有効にします。
    
    
    
    このような外部モジュールは、既に二つ存在していて、
    mod_whatkilledus と mod_backtrace
    がこのフックを活用します。これらの詳細については Jeff Trawick 
    さんの EnableExceptionHook site を参照してください。

    GracefulShutdownTimeout ディレクティブ
    

    

    説明:穏やかな停止をかけた後、終了するまで待つ時間
    

    構文:GracefulShutDownTimeout seconds
    

    デフォルト:GracefulShutDownTimeout 0
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:prefork, worker, event
    

    互換性:2.2 以降
    

    
    
    GracefulShutdownTimeout には
    サーバーが "graceful-stop" シグナルを受け取ってから現在の
    リクエストの処理を最大で何秒間続けるかを指定します。
    

    
    この値をゼロに設定すると、処理中として残っているリクエストが
    全て完了するまでサーバーは終了しません。

    Listen ディレクティブ
    

    

    説明:サーバが listen するIP アドレスとポート番号
    

    構文:Listen [IP-address:]portnumber [protocol]
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_netware, mpm_winnt, mpmt_os2, perchild, prefork, threadpool, worker, event
    

    互換性:Apache 2.0 から必須ディレクティブ。protocol
引数は 2.1.5 で追加。
    

    
    
    Listen ディレクティブは Apache
    が特定の IP アドレスやポート番号だけを listen するように指定します。
    デフォルトでは全ての IP インターフェースのリクエストに応答します。
    Listen ディレクティブは
    現在は必須のディレクティブとなりました。
    もし設定ファイルになければ、サーバは起動に失敗します。
    これは以前のバージョンの Apache から変更のあった部分です。
    

    
    Listen ディレクティブでは、特定のポートあるいは
    アドレスとポートの組み合わせから入ってくるリクエストに対して
    応答するように指定します。
    もしポート番号だけが指定された場合は、サーバは全インターフェースの
    指定されたポート番号に対して listen します。
    IP アドレスがポートとともに指定された場合は、
    サーバは指定されたポートとインターフェースに対して listen 
    します。
    

    
    複数のアドレスとポートに対して listen するように、
    複数の Listen ディレクティブを使うこともできます。
    サーバは列挙されたアドレスとポート全てからのリクエストに対して
    応答します。
    

    
    例えば、サーバが 80 番ポートと 8000 番ポートの両方の
    コネクションを受け入れる場合は、次のようにします。
    

    
    
       Listen 80
    
       Listen 8000
    
    

    
    二つの特定のインターフェースとポート番号からのコネクションを
    受け入れるようにするには、次のようにします。
    

    
    
       Listen 192.170.2.1:80
    
       Listen 192.170.2.5:8000
    
    

    
    IPv6 アドレスは角括弧で囲まなければなりません。
    例えば次の例のようにです。
    

    
    
       Listen [2001:db8::a00:20ff:fea7:ccea]:80
    
    

    
    protocol オプション引数は通常の設定では必要ありません。
       無指定の場合、443 番ポートには https が、他のポートには
       http がデフォルト値として使用されます。
       protocol 指定は、どのモジュールがリクエストを処理するかを決定し、
       AcceptFilter 
       によるプロトコル特有の最適化を行うようにします。
    

    
    非標準なポートで運用している際にのみ protocol 指定が必要になります。
       たとえば https なサイトを 8443 番ポートで運用している場合 :
    

    
    
      Listen 192.170.2.1:8443 https
    
    

    
    エラー条件
    
      同一 IP アドレスとポートの組に、複数の Listen 
      ディレクティブを指定してしまうと、Address already in use 
      というエラーメッセージを受けることになります。

    ListenBackLog ディレクティブ
    

    

    説明:保留状態のコネクションのキューの最大長
    

    構文:ListenBacklog backlog
    

    デフォルト:ListenBacklog 511
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_netware, mpm_winnt, mpmt_os2, perchild, prefork, threadpool, worker
    

    
    
    保留状態のコネクションのキューの最大長です。
    一般的には調整する必要はありませんし、調整は望ましくありません。
    しかし、TCP SYN フラッドアタックの状況下におかれる場合に、
    増やした方が望ましいシステムもあります。
    listen(2) システムコールのバックログパラメータを
    ご覧下さい。
    

    
    この値は OS により、小さな数に抑えられます。
    値は OS 毎に異なっています。また多くの OS では、
    バックログとして指定されている値ちょうどまで使っているわけではなく、
    設定されている値に基づいて (通常は設定値よりも大きな値を)
    使っていることに注意してください。

    ListenCoresBucketsRatio ディレクティブ
    

    

    説明:Ratio between the number of CPU cores (online) and the number of
listeners' buckets
    

    構文:ListenCoresBucketsRatio ratio
    

    デフォルト:ListenCoresBucketsRatio 0 (disabled)
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:event, worker, prefork

the socket option SO_REUSEPORT and distributing new connections
evenly across listening processes' (or threads') sockets using it (eg. Linux
3.9 and later, but not the current implementations of SO_REUSEPORT
in *BSDs.

    ステータス:MPM
    

    モジュール:beos, leader, mpm_netware, prefork, threadpool, worker, mpm_winnt
    

    
    
    MaxMemFree ディレクティブは
    free() が呼ばれない限り、
    主アロケータが保持できる空のメモリの最大値をキロバイト単位で設定します。
    設定されていないか、零に設定されているときは、無制限になります。

    MaxSpareThreads ディレクティブ
    

    

    説明:アイドルスレッドの最大数
    

    構文:MaxSpareThreads number
    

    デフォルト:詳細は使用法をご覧下さい。
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_netware, mpmt_os2, perchild, threadpool, worker
    

    
    
    アイドルなスレッドの最大数です。異なる MPM ではそれぞれ、
    このディレクティブは異なる取り扱われ方をされます。
    

    
    perchild では、
    デフォルトは MaxSpareThreads 10 です。
    この MPM はアイドルスレッド数を、それぞれの子プロセスごとに監視します。
    子プロセスにアイドルスレッドが多すぎる場合は、
    サーバはその子プロセスに含まれるスレッドを終了し始めます。
    

    
    worker, leader,
    threadpool では、
    デフォルトは MaxSpareThreads 250 です。
    この MPM はアイドルスレッド数をサーバ全体で監視します。
    サーバでアイドルスレッド数が多すぎる場合は、
    この数字よりも少ない数になるまで子プロセスを終了します。
    

    
    mpm_netware では、
    デフォルトは MaxSpareThreads 100 です。
    この MPM はシングルプロセスで実行されますので、
    スペアスレッド数もサーバ全体で勘定します。
    

    
    beos と mpmt_os2 は
    mpm_netware と似た挙動をします。
    beos でのデフォルト値は MaxSpareThreads 50
    です。mpmt_os2 でのデフォルト値は 10
    です。
    

    
    制限事項
    
      
    MaxSpareThreads の取る値には制限があります。
      Apache は次の規則に従って自動的に補正します。

    MinSpareThreads ディレクティブ
    

    

    説明:リクエストに応答することのできる
アイドルスレッド数の最小数
    

    構文:MinSpareThreads number
    

    デフォルト:詳細は使用方法をご覧下さい。
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_netware, mpmt_os2, perchild, threadpool, worker
    

    
    
    リクエストに応答するスレッド数の最小値です。
    異なる MPM ではそれぞれ、
    このディレクティブは異なる取り扱われ方をします。
    

    
    perchild では、
    デフォルトは MinSpareThreads 5 で、
    アイドルスレッド数を子プロセス毎に監視します。
    もし子プロセスに十分な数のスレッドがなければ、
    サーバはその子プロセスに新しいスレッドを作り始めます。
    ですから、NumServers
    を 10 に、MinSpareThreads を
    5 にした場合は、最小でも 50 のアイドルスレッドが
    システム上にあることになります。
    

    
    worker, leader,
    threadpool では、
    デフォルトは MinSpareThreads 75 で、
    アイドルスレッド数をサーバ全体で監視します。
    もしサーバに十分な数のアイドルスレッドがなければ、
    アイドルスレッド数がこの数 number よりも大きくなるまで
    新しい子プロセスが生成されます。
    

    
    mpm_netware では、
    デフォルトは MinSpareThreads 10 で、
    シングルプロセス MPM ですので、サーバ全体で管理されます。
    

    
    beos と mpmt_os2 は、
    mpm_netwareによく似ています。
    beos でのデフォルトは MinSpareThreads 1
    です。mpmt_os2 でのデフォルトは
    5 です。

    PidFile ディレクティブ
    

    

    説明:デーモンのプロセス ID
をサーバが記録するためのファイル
    

    構文:PidFile filename
    

    デフォルト:PidFile logs/httpd.pid
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_winnt, mpmt_os2, perchild, prefork, threadpool, worker
    

    
    
    PidFile ディレクティブで、
    デーモンのプロセス ID をサーバが記録するファイルを設定します。
    ファイル名が絶対パスでない場合は、
    ServerRoot
    からの相対的なものとして扱われます。
    

    
    例
    
    PidFile /var/run/apache.pid
    
    

    
    サーバが ErrorLog
    や TransferLog
    を閉じて開き直したり、設定ファイルを
    再読込したりさせるために、サーバにシグナルを送ることができると
    便利なことがあります。
    これは SIGHUP (kill -1) シグナルを PidFile
    に書かれているプロセス ID に送ることでできます。
    

    
    PidFile には、ログファイルの設置位置や
    セキュリティ
    と全く同じ注意点があります。
    

    
    注意
    
      
    Apache 2 では、
      apachectl
      スクリプトのみを使用してサーバの (再) 起動や停止を
      行なうことを推奨しています。

    ReceiveBufferSize ディレクティブ
    

    

    説明:TCP 受信バッファサイズ
    

    構文:ReceiveBufferSize bytes
    

    デフォルト:ReceiveBufferSize 0
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, mpm_netware, mpm_winnt, mpmt_os2, prefork, worker
    

    
    
    サーバは TCP 受信バッファサイズを指定されたバイト数に設定します。
    

    
    0にした場合、OS のデフォルト値が使用されます。
    


    

    top
    

    ScoreBoardFile ディレクティブ
    

    

    説明:子プロセスと連携するためのデータを保存する
ファイルの位置
    

    構文:ScoreBoardFile file-path
    

    デフォルト:ScoreBoardFile logs/apache_status
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:beos, leader, mpm_winnt, perchild, prefork, threadpool, worker
    

    
    
    Apache は親プロセスと子プロセス間の通信にスコアボードを用います。
    この通信機能にファイルを必要とするアーキテクチャもあります。
    ファイルが指定されていなければ、Apache はまずメモリ上
    (匿名共有メモリ) にスコアボードを作ろうとし、それが失敗すると
    ディスク上にファイル (ファイルベースの共有メモリ) を作ろうとします。
    このディレクティブを指定すると、Apache
    は必ずディスクにファイルを生成します。
    

    
    例
    
      ScoreBoardFile /var/run/apache_status
    
    

    
    ファイルベースの共有メモリは、サードパーティー製のアプリケーションで
    スコアボードに直接アクセスする必要がある場合に役に立ちます。
    

    
    ScoreBoardFile を使う場合、
    RAM ディスク上に置くとスピードが向上するでしょう。
    しかし、ログファイルの設置位置や
    セキュリティ
    と同様の注意点があるので、注意してください。

    サーバは TCP 送信バッファサイズを指定されたバイト数に設定します。
    高速で高レイテンシな環境で
    (例 100ms 程度、大陸横断高速通信路など)
    古い一般的な OS のデフォルト値を増やすのに非常に便利です。
    

    
    0にした場合、OS のデフォルト値が使用されます。

    デフォルト:詳細は使用法を参照
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:MPM
    

    モジュール:leader, perchild, prefork, threadpool, worker
    

    
    
    prefork MPM の場合は、このディレクティブは
    Apache プロセス稼働中における
    MaxClients
    に設定可能な上限値を設定することになります
    (訳注: prefork の場合は同時クライアント数 = サーバプロセス数なので)。
    worker MPM の場合には、このディレクティブは
    ThreadLimit
    ディレクティブと組み合わせて、
    Apache プロセス稼働中における
    MaxClients
    に設定可能な上限値を設定することになります。
    このディレクティブを変更して再起動(訳注: apachectl
    restart)しても無視されますが、
    MaxClients
    は再起動で変更することができます。
    
    

    
    このディレクティブを使用する際は特に注意してください。
    ServerLimit が必要以上に大きな値に
    設定された場合は、余計な未使用共有メモリが割り当てられます。
    ServerLimit と
    MaxClients
    がシステムの扱える範囲を越えた設定値になっていると、
    Apache は起動しないか、起動しても不安定になるでしょう。
    

    
    prefork MPM では、
    MaxClients
    を 256 (デフォルト) よりも大きな値に設定する必要がある時にだけ使用してください。
    希望の MaxClients
    数とくらべて、必要以上に大きな値を指定することは避けてください。
    

    
    worker, leader, 
    threadpool MPM では、
    MaxClients と
    ThreadsPerChild
    の設定で 16 サーバプロセス (デフォルト) 
    以上必要になる場合にのみ使用してください。希望の
    MaxClients  と
    ThreadsPerChild
    とくらべて、必要となるサーバプロセス数以上に大きな値を
    設定することは避けてください。
    

    
    perchild MPM では、
    NumServers を 8 (デフォルト)
    よろいも大きな値に設定する必要があるときにのみ使用してください。
    

    
    注意
    
      
    ServerLimit 20000 という制限付きでコンパイルされています
      (prefork MPM では 200000) 。
      これはスペルミスによって誤って酷い状況になるのを、
      回避するための処置です。

    起動時に生成されるスレッドの数です。
    スレッド数は負荷に応じて動的に制御されますので、
    通常はこの値を調整する理由はあまりないでしょう。
    

    
    perchild でのデフォルトは
    StartThreads 5 で、このディレクティブは起動時に
    プロセス毎のスレッド数を追跡します。
    

    
    mpm_netware でのデフォルトは
    StartThreads 50 で、
    この場合プロセスは一つしかないので、
    起動時にリクエストに応答するスレッドの総数となります。
    

    
    beos でのデフォルトは StartThreads
    10 です。
    また、起動時に生成されるスレッドの総数にも反映されます。

    このディレクティブは
    Apache プロセス稼働中における
    ThreadsPerChild
    に設定可能な上限値を設定します。再起動時にこのディレクティブの値を
    変更しても無視されますが、
    ThreadsPerChild
    は再起動中に、このディレクティブで指定された上限値まで
    変更することができます。
    

    
    このディレクティブを使用する際は特に注意してください。
    ThreadLimit が
    ThreadsPerChild
    よりもずっと大きな値に設定された場合は、
    余計な未使用共有メモリが割り当てられてしまいます。
    ThreadLimit が
    ThreadsPerChild
    の両方がシステムの扱える範囲を超えている場合は、
    Apache は起動しないか、起動したとしても不安定になるでしょう。
    このディレクティブの値は今使用している Apache の ThreadsPerChild の予想上限値を
    超えた値には設定しないでください。
    
    

    
    ThreadLimit のデフォルト値は
    mpm_winnt のときは 1920 で、
    他の場合は 64 です。
    

    
    注意
    
      
    ThreadLimit 20000 (mpm_winnt
      の場合は ThreadLimit 15000 )
      という制限付きでコンパイルされています。
      これはスペルミスによって誤って酷い状況になるのを、
      回避するための処置です。

    子プロセスが一つしかないような MPM を利用しているのであれば、
    この値はサーバの負荷全体を十分取り扱える程度に、
    大きくなければなりません。worker のような、
    子プロセスが複数あるような MPM を利用しているのであれば、
    サーバの通常負荷を十分扱える程度に、
    スレッド総数が多くなければなりません。

    クライアントコネクションを受け持ち、コネクション処理に必要なモジュールの
    呼び出しを行なっているスレッドの、(自動変数用の) スタックサイズは
    ThreadStackSize ディレクティブで指定します。
    大抵の場合 OS の指定しているスタックサイズのデフォルト値は
    適切なものですが、調整が必要になる場合もあります:
    

    
      
      
    • スレッドスタックサイズのデフォルト値が比較的小さく設定されている
      プラットホーム (例えば HP-UX) では、自動変数用の領域で大きな容量を
      使用するサードパーティ製モジュールのために Apache がクラッシュする
      場合もあります。そのモジュールは他のプラットホームでは
      スタックサイズが大きいために、快調に動作するかもしれません。
      このタイプのクラッシュは、ThreadStackSize
      で OS のデフォルト値より大きな値を指定することで解決します。
      サードパーティ製モジュールでこの処置が必要であると記載されている
      場合か、Apache の出力するメッセージでスレッドスタックサイズが
      小さすぎると指摘されている場合にのみ、この調整をしてください。
      • 

      
    • デフォルトスレッドスタックサイズが、Web サーバ用途に必要な量よりも
      明らかに大きすぎる場合、ThreadStackSize 
      を OS のデフォルト値よりも小さな値にすることで、子プロセスあたりの
      スレッド数をより多く持たせられるようになります。
      このタイプの調整は、テスト環境でウェブサーバを完全に
      テストできる場合に限って行なうべきです。
      まれに多数のスタックが要求されるリクエストを受けることがあるかも
      しれないからです。
      Web サーバの設定を変更すると、現在の ThreadStackSize 
      の設定が取り消される場合があります。

    Sommaire
    

    
    Ce module implémente l'authentification HTTP basée sur les
    condensés MD5 (RFC2617), et
    fournit une alternative à mod_auth_basic en
    ne transmettant plus le mot de passe en clair. Cependant, cela ne
    suffit pas pour améliorer la sécurité de manière significative par
    rapport à l'authentification basique. En outre, le stockage du mot
    de passe sur le serveur est encore moins sûr dans le cas
    d'une authentification à base de condensé que dans le cas d'une
    authentification basique. C'est pourquoi l'utilisation de
    l'authentification basique associée à un chiffrement de la connexion
    via mod_ssl constitue une bien meilleure
    alternative.
    

    


    top
    

    

    Utilisation de l'authentification à base de
condensés
    

    
    Pour utiliser l'authentification à base de condensés MD5, vous
    devez simplement remplacer AuthType Basic et AuthBasicProvider respectivement
    par AuthType Digest et AuthDigestProvider lorsque vous
    configurez l'authentification, puis ajouter une directive AuthDigestDomain contenant au
    moins la(les) URI(s) racine(s) de la zone à protéger.
    

    
    On peut créer les fichiers utilisateur appropriés (au format
    texte) à l'aide de l'outil htdigest.
    

    
    Exemple :
    <Location "/private/">
    AuthType Digest
    AuthName "private area"
    AuthDigestDomain "/private/" "http://mirror.my.dom/private2/"
    
    AuthDigestProvider file
    AuthUserFile "/web/auth/.digest_pw"
    Require valid-user
</Location>
    

    

    
    Note
    
    
    L'authentification à base de condensé a été conçue pour améliorer
    la sécurité par rapport à l'authentification basique, mais il
    s'avère que ce but n'a pas été atteint. Un attaquant de type
    "man-in-the-middle" peut facilement forcer le navigateur à revenir à
    une authentification basique. Même une oreille indiscrète passive
    peut retrouver le mot de passe par force brute avec les moyens
    modernes, car l'algorithme de hashage utilisé par l'authentification
    à base de condensé est trop rapide. Autre problème, le stockage des
    mots de passe sur le serveur n'est pas sûr. Le contenu d'un fichier
    htdigest volé peut être utilisé directement pour l'authentification
    à base de condensé. Il est donc fortement recommandé d'utiliser
    mod_ssl pour chiffrer la connexion.
    
    
    mod_auth_digest ne fonctionne correctement que
    sur les plates-formes où APR supporte la mémoire partagée.

    Directive AuthDigestAlgorithm

    sélectionner l'algorithme utilisé pour calculer les condensés du
    défit et de sa réponse.
    

    
    
      MD5-sess n'est pas encore correctement implémenté.

    Directive AuthDigestDomain
    

    

    Description:Les URIs qui se trouvent dans le même espace de protection
concernant l'authentification à base de condensés
    

    Syntaxe:AuthDigestDomain URI [URI] ...
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_auth_digest
    

    
    
    La directive AuthDigestDomain vous permet
    de spécifier un ou plusieurs URIs se trouvant dans le même
    espace de protection (c'est à dire utilisant le même utilisateur/mot
    de passe et se trouvant dans le même domaine). Les URIs spécifiés
    sont des préfixes ; le client doit savoir que tous les URIs situés
    sous ces préfixes seront protégés par le même utilisateur/mot de
    passe. Les URIs peuvent être soit des URIs absolus (c'est à dire
    avec protocole, nom serveur, port, etc...), soit des URIs
    relatifs.
    

    
    Cette directive doit toujours être présente et contenir au moins
    le(s) URI(s) racine(s) pour cet espace. Dans le cas contraire, le
    client va envoyer un en-tête d'autorisation avec chaque
    requête à destination de ce serveur.
    

    
    Les URIs spécifiés peuvent aussi référencer différents serveurs,
    auquel cas les clients (qui sont à même de le comprendre) vont
    partager l'utilisateur/mot de passe entre plusieurs serveurs sans le
    demander à l'utilisateur à chaque fois.

    La directive AuthDigestNonceLifetime
    permet de contrôler la durée de validité du nombre à valeur unique
    du serveur (nonce). Lorsque le client contacte le serveur en
    utilisant un nonce dont la validité a expiré, le serveur renvoie un
    code d'erreur 401 avec stale=true. Si
    secondes est supérieur à 0, il spécifie la durée de
    validité du nonce ; il est en général déconseillé d'affecter à cet
    argument une valeur inférieure à 10 secondes. Si
    secondes est inférieur à 0, le nonce n'expire jamais.

    La directive AuthDigestProvider permet de
    définir quel fournisseur d'authentification sera utilisé pour
    authentifier les utilisateurs pour la zone du site web concernée.
    Assurez-vous que le module implémentant le fournisseur
    d'authentification choisi soit bien présent dans le serveur. Le
    fournisseur par défaut file est implémenté par le
    module mod_authn_file.
    

    
    Voir mod_authn_dbm,

    Module:mod_auth_digest
    

    
    
    La directive AuthDigestQop permet de
    définir le niveau de protection fourni. auth
    ne fournit que l'authentification (nom utilisateur/mot de passe) ;
    auth-int fournit l'authentification plus un contrôle
    d'intégrité (un condensé MD5 de l'entité est aussi calculé et
    vérifié) ; avec none, le module va utiliser l'ancien
    algorithme de condensés RFC-2069 (qui n'effectue pas de contrôle
    d'intégrité). On peut spécifier à la fois auth et
    auth-int, auquel cas c'est le navigateur qui va choisir
    lequel des deux utiliser. none ne doit être utilisé que
    dans le cas où le navigateur ne serait pas à même (pour une raison
    ou pour une autre) de relever le défit qu'il recevrait si un autre
    niveau de protection était défini.
    

    
    
      auth-int n'est pas encore implémenté.

    Contexte:configuration globale
    

    Statut:Extension
    

    Module:mod_auth_digest
    

    
    
    La directive AuthDigestShmemSize permet de
    définir la quantité de mémoire partagée à allouer au démarrage du
    serveur afin de conserver les informations à propos des clients.
    Notez que le segment de mémoire partagée ne peut pas être défini à
    une taille inférieure à l'espace nécessaire pour conserver les
    informations à propos d'un client. Cette valeur dépend de
    votre système. Si vous voulez en déterminer la valeur exacte, vous
    pouvez simplement définir AuthDigestShmemSize
    à 0 et consulter le message d'erreur que renverra le
    serveur lorsqu'on essaiera de le démarrer.
    

    
    L'argument size s'exprime par défaut en octets, mais
    vous pouvez suffixer le nombre par un K ou un
    M pour spécifier respectivement des KiloOctets ou des
    MégaOctets. Par exemple, les directives qui suivent sont toutes
    équivalentes :
    

    
    AuthDigestShmemSize 1048576
AuthDigestShmemSize 1024K
AuthDigestShmemSize 1M

    Summary
    


    
    This module provides a magic token for each request which is
    guaranteed to be unique across "all" requests under very
    specific conditions. The unique identifier is even unique
    across multiple machines in a properly configured cluster of
    machines. The environment variable UNIQUE_ID is
    set to the identifier for each request. Unique identifiers are
    useful for various reasons which are beyond the scope of this
    document.

    Theory
    
    

    
    First a brief recap of how the Apache server works on Unix
    machines. This feature currently isn't supported on Windows NT.
    On Unix machines, Apache creates several children, the children
    process requests one at a time. Each child can serve multiple
    requests in its lifetime. For the purpose of this discussion,
    the children don't share any data with each other. We'll refer
    to the children as httpd processes.
    

    
    Your website has one or more machines under your
    administrative control, together we'll call them a cluster of
    machines. Each machine can possibly run multiple instances of
    Apache. All of these collectively are considered "the
    universe", and with certain assumptions we'll show that in this
    universe we can generate unique identifiers for each request,
    without extensive communication between machines in the
    cluster.
    

    
    The machines in your cluster should satisfy these
    requirements. (Even if you have only one machine you should
    synchronize its clock with NTP.)
    

    
      
      
    • The machines' times are synchronized via NTP or other
      network time protocol.
      • 

      
    • The machines' hostnames all differ, such that the module
      can do a hostname lookup on the hostname and receive a
      different IP address for each machine in the cluster.
      • 
    
    

    
    As far as operating system assumptions go, we assume that
    pids (process ids) fit in 32-bits. If the operating system uses
    more than 32-bits for a pid, the fix is trivial but must be
    performed in the code.
    

    
    Given those assumptions, at a single point in time we can
    identify any httpd process on any machine in the cluster from
    all other httpd processes. The machine's IP address and the pid
    of the httpd process are sufficient to do this. A httpd process
    can handle multiple requests simultaneously if you use a
    multi-threaded MPM. In order to identify threads, we use a thread
    index Apache httpd uses internally. So in order to
    generate unique identifiers for requests we need only
    distinguish between different points in time.
    

    
    To distinguish time we will use a Unix timestamp (seconds
    since January 1, 1970 UTC), and a 16-bit counter. The timestamp
    has only one second granularity, so the counter is used to
    represent up to 65536 values during a single second. The
    quadruple ( ip_addr, pid, time_stamp, counter ) is
    sufficient to enumerate 65536 requests per second per httpd
    process. There are issues however with pid reuse over time, and
    the counter is used to alleviate this issue.
    

    
    When an httpd child is created, the counter is initialized
    with ( current microseconds divided by 10 ) modulo 65536 (this
    formula was chosen to eliminate some variance problems with the
    low order bits of the microsecond timers on some systems). When
    a unique identifier is generated, the time stamp used is the
    time the request arrived at the web server. The counter is
    incremented every time an identifier is generated (and allowed
    to roll over).
    

    
    The kernel generates a pid for each process as it forks the
    process, and pids are allowed to roll over (they're 16-bits on
    many Unixes, but newer systems have expanded to 32-bits). So
    over time the same pid will be reused. However unless it is
    reused within the same second, it does not destroy the
    uniqueness of our quadruple. That is, we assume the system does
    not spawn 65536 processes in a one second interval (it may even
    be 32768 processes on some Unixes, but even this isn't likely
    to happen).
    

    
    Suppose that time repeats itself for some reason. That is,
    suppose that the system's clock is screwed up and it revisits a
    past time (or it is too far forward, is reset correctly, and
    then revisits the future time). In this case we can easily show
    that we can get pid and time stamp reuse. The choice of
    initializer for the counter is intended to help defeat this.
    Note that we really want a random number to initialize the
    counter, but there aren't any readily available numbers on most
    systems (i.e., you can't use rand() because you need
    to seed the generator, and can't seed it with the time because
    time, at least at one second resolution, has repeated itself).
    This is not a perfect defense.
    

    
    How good a defense is it? Suppose that one of your machines
    serves at most 500 requests per second (which is a very
    reasonable upper bound at this writing, because systems
    generally do more than just shovel out static files). To do
    that it will require a number of children which depends on how
    many concurrent clients you have. But we'll be pessimistic and
    suppose that a single child is able to serve 500 requests per
    second. There are 1000 possible starting counter values such
    that two sequences of 500 requests overlap. So there is a 1.5%
    chance that if time (at one second resolution) repeats itself
    this child will repeat a counter value, and uniqueness will be
    broken. This was a very pessimistic example, and with real
    world values it's even less likely to occur. If your system is
    such that it's still likely to occur, then perhaps you should
    make the counter 32 bits (by editing the code).
    

    
    You may be concerned about the clock being "set back" during
    summer daylight savings. However this isn't an issue because
    the times used here are UTC, which "always" go forward. Note
    that x86 based Unixes may need proper configuration for this to
    be true -- they should be configured to assume that the
    motherboard clock is on UTC and compensate appropriately. But
    even still, if you're running NTP then your UTC time will be
    correct very shortly after reboot.
    

    
    
    The UNIQUE_ID environment variable is
    constructed by encoding the 144-bit (32-bit IP address, 32 bit
    pid, 32 bit time stamp, 16 bit counter, 32 bit thread index)
    quadruple using the
    alphabet [A-Za-z0-9@-] in a manner similar to MIME
    base64 encoding, producing 24 characters. The MIME base64
    alphabet is actually [A-Za-z0-9+/] however
    + and / need to be specially encoded
    in URLs, which makes them less desirable. All values are
    encoded in network byte ordering so that the encoding is
    comparable across architectures of different byte ordering. The
    actual ordering of the encoding is: time stamp, IP address,
    pid, counter. This ordering has a purpose, but it should be
    emphasized that applications should not dissect the encoding.
    Applications should treat the entire encoded
    UNIQUE_ID as an opaque token, which can be
    compared against other UNIQUE_IDs for equality
    only.
    

    
    The ordering was chosen such that it's possible to change
    the encoding in the future without worrying about collision
    with an existing database of UNIQUE_IDs. The new
    encodings should also keep the time stamp as the first element,
    and can otherwise use the same alphabet and bit length. Since
    the time stamps are essentially an increasing sequence, it's
    sufficient to have a flag second in which all machines
    in the cluster stop serving any request, and stop using the old
    encoding format. Afterwards they can resume requests and begin
    issuing the new encodings.
    

    
    This we believe is a relatively portable solution to this
    problem. The identifiers
    generated have essentially an infinite life-time because future
    identifiers can be made longer as required. Essentially no
    communication is required between machines in the cluster (only
    NTP synchronization is required, which is low overhead), and no
    communication between httpd processes is required (the
    communication is implicit in the pid value assigned by the
    kernel). In very specific situations the identifier can be
    shortened, but more information needs to be assumed (for
    example the 32-bit IP address is overkill for any site, but
    there is no portable shorter replacement for it).

    説明:ユーザの指定した基準に基づいた Expires と
Cache-Control HTTP ヘッダの生成
    

    ステータス:Extension
    

    モジュール識別子:expires_module
    

    ソースファイル:mod_expires.c
    

    概要
    

    
    このモジュールはサーバ応答の Expires HTTP ヘッダ
    と Cache-Control ヘッダの max-age ディレクティブの
    設定を制御します。元のファイルが作成された時刻または
    クライアントのアクセス時刻のどちらかに基づいて期限切れ日を
    設定することができます。
    

    
    これらのヘッダはクライアントに文書の
    有効性と継続性を指示します。文書がキャッシュされた場合には、
    指定時刻に達するまでは、元の場所から取得する代わりに
    キャッシュされているものを使うことができます。その後は、
    キャッシュにあるコピーは期限切れ (expired) で無効であるとされ、
    元の場所から新しいものを取得する必要があります。
    

    
    max-age 以外 (RFC
    2616 section 14.9 参照) の Cache-Control のディレクティブを
    操作するには Header ディレクティブを
    使うことができます。

    代替期間指定構文
    
   
    
    ExpiresDefault ディレクティブと
    ExpiresByType ディレクティブは
    以下のより読み易い構文を使って定義することができます:
    

    
    
      ExpiresDefault "<base> [plus] {<num>
      <type>}*"
    
      ExpiresByType type/encoding "<base> [plus]
      {<num> <type>}*"
    
    

    
    <base> は以下のどれかです:
    

    
      
      
    • access
      • 

      
    • now ('access' と等価)
      • 

      
    • modification
      • 
    
    

    
    plus キーワードは省略可能です。<num>
    は (atoi() が受け付ける) 整数値、
    <type> は以下のどれかです:
    

    
      
      
    • years
      • 
      
    • months
      • 
      
    • weeks
      • 
      
    • days
      • 
      
    • hours
      • 
      
    • minutes
      • 
      
    • seconds
      • 
    
    

    
    例えば、以下のディレクティブはどれもデフォルトで文書がアクセスの 1 ヶ月後に
    期限が切れるようにするために使えます:
    

    
    
      ExpiresDefault "access plus 1 month"
    
      ExpiresDefault "access plus 4 weeks"
    
      ExpiresDefault "access plus 30 days"
    
    

    
    期限切れ時刻はいくつか
    '<num> <type>' 節を追加することでより細かく
    制御することができます:
    

    
    
      ExpiresByType text/html "access plus 1 month 15
      days 2 hours"
    
      ExpiresByType image/gif "modification plus 5 hours 3
      minutes"
    
    

    
    修正時刻に基づいた設定を使用している場合、Expires ヘッダは
    ディスクのファイル以外のコンテンツには追加されないことに注意
    してください。そのようなコンテンツには修正時刻は存在しないからです。

    ExpiresActive ディレクティブ

    このディレクティブは対応するドキュメントの領域で
    Expires と Cache-Controlヘッダを
    有効にするか無効にするかを決めます。
    (例えば、.htaccess ファイルではそのディレクトリの
    文書のみに適用されるということです。) Off に
    設定された場合は対応領域でそれらのヘッダは
    生成されません (.htaccess がサーバ設定ファイルの設定を
    上書きする、というような下位レベルでの上書きがされていなければ)。
    On に設定されていれば、ヘッダは ExpiresByType ディレクティブと
    ExpiresDefault ディレクティブ
    の基準に従って文書にヘッダを追加します (各ディレクティブ参照)。
    

    
    このディレクティブは Expires と
    Cache-Control ヘッダの存在を
    保証するわけではないことに注意してください。基準が満たされて
    いない場合はヘッダは追加されず、結果としてこのディレクティブが
    指定されていなかったかのようにさえ見えることになります。

    説明:MIME タイプによって設定される Expires ヘッダの値

    このディレクティブは指定されたタイプのドキュメント
    (例えば text/html)
    に対して生成される Expires ヘッダと Cache-Control
    ヘッダの max-age ディレクティブの値を定義します。
    二つ目の引数は期限切れの日時を生成するための基準時刻に追加される
    秒数を設定します。Cache-Control:
    max-age は期限切れの時刻からリクエスト時刻を引いたものを秒で
    表すことで生成されます。
    

    
    基準時刻はファイルの最終修正時刻か、クライアントのドキュメントへの
    アクセス時刻です。どちらを使うべきかは <code>
    によって指定します。M は基準時刻として
    ファイルの最終修正時刻をという意味で、A はクライアントの
    アクセス時刻を使うという意味になります。
    

    
    効果には微妙な違いがあります。M が使用された場合は、
    すべてのキャッシュにある現在のドキュメントキャッシュは同時に期限が
    切れます。これは同じ URL に毎週常に置かれる報せのようなものには
    非常に有効です。A が使用された場合は、期限切れの
    時間は各クライアントよって異なります。これはあまり変更されない
    画像ファイルなど、特に関連するドキュメント群がすべて同じ画像を
    参照するとき (すなわち画像が比較的短い期間内に繰り返し
    アクセスされるとき) に有効です。
    

    
    例:
    
      # enable expirations
    
      ExpiresActive On
    
      # expire GIF images after a month in the client's cache
    
      ExpiresByType image/gif A2592000
    
      # HTML documents are good for a week from the
    
      # time they were changed
    
      ExpiresByType text/html M604800
    
    

    
    このディレクティブは ExpiresActive On が指定されている
    ときのみ有効であることに注意してください。これは、
    指定された MIME タイプに対してのみ ExpiresDefault ディレクティブで
    設定された期限切れ期日を上書きします。
    

    
    この文書の前の方で説明されている代替構文を
    使って期限切れ期日の計算方法を指定することもできます。

    Sommaire
    

    
    lbmethod=heartbeat utilise les services du module
    mod_heartmonitor pour répartir la charge entre les
    serveurs d'origine qui fournissent des données heartbeat via le
    module mod_heartbeat.
    


    Son algorithme de répartition de charge favorise les serveurs dont la
capacité de traitement moyenne répartie dans le temps est la plus
importante, mais il ne sélectionne pas forcément le serveur qui présente
la disponibilité instantanée la plus importante. Les serveurs qui ne
possèdent aucun client actif sont pénalisés, car ils sont considérés
comme non entièrement initialisés.

    Açıklama:Evresiz ön çatallamalı HTTP sunucusu oluşturur

    Modül Betimleyici:mpm_prefork_module
    

    Kaynak Dosyası:prefork.c
    

    Özet
    

    
    Bu çok süreçlilik modülü (MPM) evresiz ve
      çocuk süreçlerin önceden çatallandığı bir HTTP sunucusu oluşturur. Her
      çocuk süreç gelen bir isteğe yanıt verirken ebeveyn süreç çocuk süreç
      havuzunu yönetir. Evresiz kütüphanelerle uyumluluk için evrelemeden
      kaçınma ihtiyacında olan siteler için uygundur. Ayrıca istekleri
      birbirlerinden yalıtmak için en iyi MPM’dir, dolayısıyla herhangi bir
      istekle ilgili bir sorun diğerlerini etkilemez.
    

    
    Bu MPM kendi kendine her duruma çok iyi uyum sağladığından
      yapılandırma yönergeleri ile yapılandırılmaya nadiren ihtiyaç gösterir.
      Yönergelerin en önemlisi MaxRequestWorkers olup, değeri aynı anda almayı umduğunuz
      istek sayısını işleyebilecek kadar büyük, fiziksel belleğin tüm
      süreçlerin ihtiyaçlarını karşılamasına yetecek kadar da küçük olması
      gerekir.

    Nasıl çalışır?
    
    
    Bağlantıları dinleyip gerektiğinde onlara hizmet sunan çocuk süreçleri
      devreye almak tek bir denetim sürecinin sorumluluğundadır. Apache httpd
      daima, gelen isteklere hizmet vermeye hazır bekleyen en fazla sayıda
      sunucu sürecini yedekte tutmaya veya boşta bekletmeye
      çalışır. Bu suretle, istemcilere isteklerinin sunulması için yeni çocuk
      süreçlerin çatallanmasını beklemek gerekmez.
    

    
    Ana sürecin istekleri sunacak çocuk süreçleri oluşturma işlemini nasıl
      gerçekleştireceği StartServers, MinSpareServers, MaxSpareServers ve MaxRequestWorkers yönergeleri ile düzenlenir. Apache httpd
      kendiliğinden her duruma çok iyi uyum sağladığından, genelde, çoğu
      sitenin bu yönergelerin öntanımlı değerlerini değiştirmesi gerekmez.
      Aynı anda 256’dan fazla isteğe hizmet sunacak sitelerin MaxRequestWorkers değerini arttırmaları
      gerekebilir. Ancak, fiziksel belleği yeterli olmayan sitelerin de
      sunucunun belleği diske takaslamasını önlemek için bu değeri
      azaltmaları gerekebilir. Süreç oluşturmanın ayarlanması ile ilgili daha
      fazla bilgi edinmek için başarım
      arttırma ipuçları belgesine bakınız.
    

    
    Unix altında 80. portu dinleyebilmek için ana sürecin
      root tarafından çalıştırılmış olması gerekirse de çocuk
      süreçler Apache httpd tarafından daha az yetkili bir kullanıcının
      aidiyetinde çalıştırılırlar. Apache httpd’nin çocuk süreçlerinin
      kullanıcı ve gruplarını ayarlamak için User ve Group
      yönergeleri kullanılır. Çocuk süreçlerin sunacakları içeriği okumaya
      yetkili olmaları gerekir, fakat bu yetkinin mümkün olduğunca kısıtlı
      tutulmasına çalışılmalıdır.
    

    
    MaxConnectionsPerChild
      yönergesi ana sunucunun eski süreçleri öldürüp yenilerini oluşturmayı
      ne kadar sıklıkla yapacağını denetler.
    

    
    Bu MPM, gürleyen sürü sorunu ortaya çıktığında (genelde çok sayıda
      dinlenen soket varlığında) gelen bağlantılara erişimi dizgileştirmek için
      mpm-accept muteksini kullanır. Bu muteksin gerçeklenimle
      ilgili hususları Mutex yönergesi ile
      yapılandırılabilir. Bu muteks hakkında ek bilgi  için başarımın arttırılması
      belgesine bakınız.

    MaxSpareServers Yönergesi
    

    

    Açıklama:Boştaki çocuk süreçlerin azami sayısı
    

    Sözdizimi:MaxSpareServers sayı
    

    Öntanımlı:MaxSpareServers 10
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:prefork
    

    
    
    MaxSpareServers yönergesi boştaki
      çocuk sunucu süreçlerinin azami sayısını belirler. Boştaki süreç, o an
      bir isteğe hizmet sunmayan süreçtir. Eğer
      MaxSpareServers sayıda süreçten daha fazla boşta
      süreç varsa ana süreç bu fazlalıkları öldürecektir.
    

    
    Bu parametrenin ayarlanması sadece çok meşgul siteler için gerekli
      olabilir. Bu parametreye çok büyük bir değerin atanması oldukça kötü
      bir fikirdir. Eğer bu değeri MinSpareServers değerine eşit veya daha küçük bir değere
      ayarlarsanız, Apache HTTP Sunucusu bu değeri kendiliğinden MinSpareServers + 1 olarak

    MinSpareServers Yönergesi
    

    

    Açıklama:Boştaki çocuk süreçlerin asgari sayısı
    

    Sözdizimi:MinSpareServers sayı
    

    Öntanımlı:MinSpareServers 5
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:prefork
    

    
    
    MinSpareServers yönergesi boştaki
      çocuk sunucu süreçlerinin asgari sayısını belirler. Boştaki süreç, o an
      bir isteğe hizmet sunmayan süreçtir. Eğer
      MinSpareServers sayıda süreçten daha az boşta
      süreç varsa ana süreç sayıyı tamamlamak için yeni çocuk süreçler
      oluşturacaktır: Bir tane oluşturur, 1 saniye bekler, sonra 2 tane
      oluşturur, 1 saniye bekler, sonra 4 tane oluşturur ve saniyede 32 çocuk
      süreç oluşturuluncaya kadar böyle üstel olarak artar. Artış
      MinSpareServers ile belirlenen sayıda
      duracaktır.
    

    
    Bu parametrenin ayarlanması sadece çok meşgul siteler için gerekli
      olabilir. Bu parametreye çok büyük bir değerin atanması oldukça kötü
      bir fikirdir.

    Description:Manages SQL database connections
    

    Status:Extension
    

    Module Identifier:dbd_module
    

    Source File:mod_dbd.c
    

    Compatibility:Version 2.1 and later
    

    Summary
    

    
    mod_dbd manages SQL database connections using
    APR.  It provides database connections on request
    to modules requiring SQL database functions, and takes care of
    managing databases with optimal efficiency and scalability
    for both threaded and non-threaded MPMs.  For details, see the
    APR website and this overview of the
    Apache DBD Framework
    by its original developer.

    Connection Pooling
    
    
    This module manages database connections, in a manner
    optimised for the platform.  On non-threaded platforms,
    it provides a persistent connection in the manner of
    classic LAMP (Linux, Apache, Mysql, Perl/PHP/Python).
    On threaded platform, it provides an altogether more
    scalable and efficient connection pool, as
    described in this
    article at ApacheTutor.  Note that mod_dbd
    supersedes the modules presented in that article.

    Connecting
    

    
    To connect to your database, you'll need to specify
    a driver, and connection parameters. These vary from
    one database engine to another. For example, to connect
    to mysql, do the following:
    


    DBDriver mysql
DBDParams host=localhost,dbname=pony,user=shetland,pass=appaloosa
    


    
    You can then use this connection in a variety of other
    modules, including mod_rewrite,
    mod_authn_dbd, and mod_lua.
    Further usage examples appear in each of those modules'
    documentation.
    

    
    See DBDParams for connection string
    information for each of the supported database drivers.
    


    top
    

    

    Apache DBD API
    
    
    mod_dbd exports five functions for other modules
    to use. The API is as follows:
    


    typedef struct {
    apr_dbd_t *handle;
    apr_dbd_driver_t *driver;
    apr_hash_t *prepared;
} ap_dbd_t;

/* Export functions to access the database */

/* acquire a connection that MUST be explicitly closed.
 * Returns NULL on error
 */
AP_DECLARE(ap_dbd_t*) ap_dbd_open(apr_pool_t*, server_rec*);

/* release a connection acquired with ap_dbd_open */
AP_DECLARE(void) ap_dbd_close(server_rec*, ap_dbd_t*);

/* acquire a connection that will have the lifetime of a request
 * and MUST NOT be explicitly closed.  Return NULL on error.
 * This is the preferred function for most applications.
 */
AP_DECLARE(ap_dbd_t*) ap_dbd_acquire(request_rec*);

/* acquire a connection that will have the lifetime of a connection
 * and MUST NOT be explicitly closed.  Return NULL on error.
 */
AP_DECLARE(ap_dbd_t*) ap_dbd_cacquire(conn_rec*);

/* Prepare a statement for use by a client module */
AP_DECLARE(void) ap_dbd_prepare(server_rec*, const char*, const char*);

/* Also export them as optional functions for modules that prefer it */
APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_open, (apr_pool_t*, server_rec*));
APR_DECLARE_OPTIONAL_FN(void, ap_dbd_close, (server_rec*, ap_dbd_t*));
APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_acquire, (request_rec*));
APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_cacquire, (conn_rec*));
APR_DECLARE_OPTIONAL_FN(void, ap_dbd_prepare, (server_rec*, const char*, const char*));

    SQL Prepared Statements
    
    
    mod_dbd supports SQL prepared statements on behalf
    of modules that may wish to use them.  Each prepared statement
    must be assigned a name (label), and they are stored in a hash:
    the prepared field of an ap_dbd_t.
    Hash entries are of type apr_dbd_prepared_t
    and can be used in any of the apr_dbd prepared statement
    SQL query or select commands.
    

    
    It is up to dbd user modules to use the prepared statements
    and document what statements can be specified in httpd.conf,
    or to provide their own directives and use ap_dbd_prepare.
    
	
	
    Caveat
    
	When using prepared statements with a MySQL database, it is preferred to set
	reconnect to 0 in the connection string as to avoid errors that
	arise from the MySQL client reconnecting without properly resetting the
	prepared statements. If set to 1, any broken connections will be attempted
	fixed, but as mod_dbd is not informed, the prepared statements will be invalidated.

    SECURITY WARNING
    

    
    Any web/database application needs to secure itself against SQL
    injection attacks.  In most cases, Apache DBD is safe, because
    applications use prepared statements, and untrusted inputs are
    only ever used as data.  Of course, if you use it via third-party
    modules, you should ascertain what precautions they may require.
    
    
    However, the FreeTDS driver is inherently
    unsafe.  The underlying library doesn't support
    prepared statements, so the driver emulates them, and the
    untrusted input is merged into the SQL statement.
    
    
    It can be made safe by untainting all inputs:
    a process inspired by Perl's taint checking.  Each input
    is matched against a regexp, and only the match is used,
    according to the Perl idiom:
    
    
      $untrusted =~ /([a-z]+)/;
  $trusted = $1;
    
    
    To use this, the untainting regexps must be included in the
    prepared statements configured.  The regexp follows immediately
    after the % in the prepared statement, and is enclosed in
    curly brackets {}.  For example, if your application expects
    alphanumeric input, you can use:
    
    
    
       "SELECT foo FROM bar WHERE input = %s"
    
    
    
    with other drivers, and suffer nothing worse than a failed query.
    But with FreeTDS you'd need:
    
    
    
       "SELECT foo FROM bar WHERE input = %{([A-Za-z0-9]+)}s"
    
    
    
    Now anything that doesn't match the regexp's $1 match is
    discarded, so the statement is safe.
    
    
    An alternative to this may be the third-party ODBC driver,
    which offers the security of genuine prepared statements.

    DBDInitSQL Directive
    

    

    Description:Execute an SQL statement after connecting to a database
    

    Syntax:DBDInitSQL "SQL statement"
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_dbd
    

    
    
    Modules, that wish it, can have one or more SQL statements 
    executed when a connection to a database is created. Example 
    usage could be initializing certain values or adding a log 
    entry when a new connection is made to the database.

    As required by the underlying driver.  Typically this will be
    used to pass whatever cannot be defaulted amongst username,
    password, database name, hostname and port number for connection.
    
    
    Connection string parameters for current drivers include:
    
    
    
    
    FreeTDS (for MSSQL and SyBase)
    
    
    username, password, appname, dbname, host, charset, lang, server
    
    
    MySQL
    
    
    host, port, user, pass, dbname, sock, flags, fldsz, group, reconnect
    
    
    Oracle
    
    
    user, pass, dbname, server
    
    
    PostgreSQL
    
    
    The connection string is passed straight through to PQconnectdb
    
    
    SQLite2
    
    
    The connection string is split on a colon, and part1:part2 is used as sqlite_open(part1, atoi(part2), NULL)
    
    
    SQLite3
    
    
    The connection string is passed straight through to sqlite3_open
    
    
    ODBC
    
    
    datasource, user, password, connect, ctimeout, stimeout, access, txmode, bufsize

    DBDPersist Directive
    

    

    Description:Whether to use persistent connections
    

    Syntax:DBDPersist On|Off
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_dbd
    

    
    
    If set to Off, persistent and pooled connections are disabled.
    A new database connection is opened when requested by a client,
    and closed immediately on release.  This option is for debugging
    and low-usage servers.
    

    
    The default is to enable a pool of persistent connections
    (or a single LAMP-style persistent connection in the case of a
    non-threaded server), and should almost always be used in operation.
    

    
    Prior to version 2.2.2, this directive accepted only the values
    0 and 1 instead of Off and
    On, respectively.

    DBDPrepareSQL Directive
    

    

    Description:Define an SQL prepared statement
    

    Syntax:DBDPrepareSQL "SQL statement" label
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_dbd
    

    
    
    For modules such as authentication that repeatedly use a
    single SQL statement, optimum performance is achieved by preparing
    the statement at startup rather than every time it is used.
    This directive prepares an SQL statement and assigns it a label.
    


    

    top
    

    DBDriver Directive
    

    

    Description:Specify an SQL driver
    

    Syntax:DBDriver name
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_dbd
    

    
    
    Selects an apr_dbd driver by name.  The driver must be installed
    on your system (on most systems, it will be a shared object or dll).
    For example, DBDriver mysql will select the MySQL
    driver in apr_dbd_mysql.so.

    Apache Module mod_proxy_wstunnel
    

    

    Available Languages:  en  |

    Description:Websockets support module for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_wstunnel_module
    

    Source File:mod_proxy_wstunnel.c
    

    Compatibility:Available in httpd 2.4.5 and later
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the tunnelling of web
    socket connections to a backend websockets server. The connection
    is automatically upgraded to a websocket connection:
    

    
    HTTP Response
    Upgrade: WebSocket
Connection: Upgrade
    

    


    Proxying requests to a websockets server like echo.websocket.org can be done using the
ProxyPass directive:
    
    
    ProxyPass "/ws2/"  "ws://echo.websocket.org/"
ProxyPass "/wss2/" "wss://echo.websocket.org/"
    


    
    Proxying both HTTP and websockets at the same time, with a specific set of URL's being
websocket-only, can be done by specifying the websockets 
ProxyPass directive before the
HTTP directive:
    

    ProxyPassMatch ^/(myApp/ws)$  ws://backend.example.com:9080/$1
ProxyPass / http://backend.example.com:9080/
    



    Proxying both HTTP and websockets at the same time, where the websockets URL's are not
websocket-only or not known in advance can be done by using the
RewriteRule directive to
configure the websockets proxying:
    

    ProxyPass / http://example.com:9080/
RewriteEngine on
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "ws://example.com:9080/$1" [P,L]
    




    Load balancing for multiple backends can be achieved using mod_proxy_balancer.
    


    In fact the module can be used to upgrade to other protocols, you can set the upgrade
parameter in the ProxyPass
directive to allow the module to accept other protocol.
NONE means you bypass the check for the header but still upgrade to WebSocket.
ANY means that Upgrade will read in the request headers and use
in the response Upgrade

    ProxyWebsocketFallbackToProxyHttp Directive
    

    

    Description:Instructs this module to let mod_proxy_http handle the request
    

    Syntax:ProxyWebsocketFallbackToProxyHttp On|Off
    

    Default:ProxyWebsocketFallbackToProxyHttp On
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy_wstunnel
    

    Compatibility:Available in httpd 2.4.48 and later
    

    
    
    Since httpd 2.4.47, mod_proxy_http can handle WebSocket
    upgrading and tunneling in accordance to RFC 7230, this directive controls
    whether mod_proxy_wstunnel should hand over to
    mod_proxy_http to this, which is the case by default.
    
    
    Setting to Off lets mod_proxy_wstunnel handle
    WebSocket requests as in httpd 2.4.46 and earlier.

    Module Apache mod_rewrite
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Ce module fournit un moteur de réécriture à base de
règles permettant de réécrire les URLs des requêtes
à la volée
    

    Statut:Extension
    

    Identificateur de Module:rewrite_module
    

    Fichier Source:mod_rewrite.c
    

    Sommaire
    

      
    Le module mod_rewrite utilise un moteur de
      réécriture à base de règles, basé sur un interpréteur
      d'expressions rationnelles PCRE, pour réécrire les URLs à la volée. Par
      défaut, mod_rewrite met en correspondance une URL
      avec le système de fichiers. Cependant, on peut aussi l'utiliser
      pour rediriger une URL vers une autre URL, ou pour invoquer une
      requête interne à destination du mandataire.
    
      
    mod_rewrite fournit une méthode souple et
      puissante pour manipuler les URLs en utilisant un nombre illimité
      de règles. Chaque règle peut être associée à un nombre illimité de
      conditions, afin de vous permettre de réécrire les URLs en
      fonction de variables du serveur, de variables d'environnement,
      d'en-têtes HTTP, ou de repères temporels.
    
      
    mod_rewrite agit sur la totalité de l'URL, y
      compris la partie chemin. Une règle de réécriture peut être
      invoquée dans httpd.conf ou dans un fichier
      .htaccess. Le chemin généré par une règle de
      réécriture peut inclure une chaîne de paramètres, ou peut renvoyer
      vers un traitement secondaire interne, une redirection vers une
      requête externe ou vers le mandataire interne.
    

      
    Vous trouverez d'avantage de détails, discussions et exemples
      dans la
      documentation détaillée
      sur mod_rewrite.

    Journalisation
    

    
    mod_rewrite offre une journalisation détaillée
    de ses actions aux niveaux de journalisation trace1 à
    trace8. Le niveau de journalisation peut être défini de
    manière spécifique à mod_rewrite via la directive
    LogLevel : jusqu'au niveau
    debug aucune action n'est journalisée, alors qu'elles
    le sont pratiquement toutes au niveau trace8.
    

    
    
      L'utilisation d'un niveau de journalisation élevé pour
      mod_rewrite va ralentir votre serveur HTTP Apache
      de manière dramatique ! N'utilisez un niveau de journalisation
      supérieur à trace2 qu'à des fins de débogage !
    
    

    
    Exemple
    LogLevel alert rewrite:trace3
    

    

    
    RewriteLog
    
      
    Ceux qui sont familiers avec les versions précédentes de
      mod_rewrite vont probablement rechercher en vain les
      directives RewriteLog et
      RewriteLogLevel. Elles ont été en effet remplacées
      par une configuration de la journalisation par module, comme
      mentionné plus haut.
      
    

      
    Pour extraire les traces spécifiques à
      mod_rewrite, affichez le fichier journal en
      redirigeant la sortie vers grep :
    
    
    
    tail -f error_log|fgrep '[rewrite:'

    Directive RewriteBase
    

    

    Description:Définit l'URL de base pour les réécritures au niveau
répertoire
    

    Syntaxe:RewriteBase chemin_URL
    

    Défaut:Pas de valeur par défaut
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_rewrite
    

    
      
    La directive RewriteBase permet de
      spécifier le préfixe d'URL à utiliser dans un contexte de
      répertoire (htaccess) pour les directives
      RewriteRule qui réécrivent vers un chemin
      relatif.
    
      
    Cette directive est obligatoire si vous utilisez un
      chemin relatif dans une substitution, et dans un contexte de
      répertoire (htaccess), sauf si au moins une de ces conditions est
      vérifiée :
    
      
      
          
    • La requête initiale, ainsi que la substitution, se
	  situent par raport à la valeur de la directive
	  DocumentRoot (c'est à
	  dire que pour y accéder, il n'est pas nécessaire d'utiliser
	  une directive telle qu'Alias).
      • 
          
    • Le chemin du système de fichiers vers le répertoire
	  contenant la RewriteRule, suffixé par
	  la substitution relative est aussi valide en tant qu'URL sur
	  le serveur (ce qui est rare).
      • 
	  
    • A partir de la version 2.4.16 du serveur HTTP Apache,
	  cette directive peut être omise lorsque la requête est mise en
	  correspondance avec le système de fichiers via la directive
	  Alias ou le module
	  mod_userdir.
      • 
      
    


    Dans l'exemple ci-dessous, la directive
RewriteBase est nécessaire afin d'éviter une
réécriture en http://example.com/opt/myapp-1.2.3/welcome.html car la
ressource n'était pas relative à la racine des documents. Cette erreur
de configuration aurait conduit le serveur à rechercher un répertoire
"opt" à la racine des documents.
    


    DocumentRoot "/var/www/example.com"
AliasMatch "^/myapp" "/opt/myapp-1.2.3"
<Directory "/opt/myapp-1.2.3">
 RewriteEngine On
    RewriteBase "/myapp/"
    RewriteRule "^index\.html$"  "welcome.html"
</Directory>

    Directive RewriteCond
    

    

    Description:Définit une condition qui devra être satisfaite pour que
la réécriture soit effectuée

    

    Syntaxe: RewriteCond
      chaîne_de_test expression_de_comparaison [drapeaux]
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_rewrite
    

    
      
    La directive RewriteCond permet de définir une
      condition d'exécution d'une règle. Une ou plusieurs conditions
      RewriteCond peuvent précéder une
      directive RewriteRule. La règle de réécriture correspondante n'est
      ainsi exécutée que si ces conditions sont satisfaites,
      et si l'URI correspond au modèle spécifié dans la
      règle.
    

      
    TestString est une chaîne qui peut contenir les
      extensions suivantes en plus du texte simple :
    

      
      
        
    • 
          références arrières de règle de réécriture :
	  ce sont des références arrières de la forme
	  $N (0 <= N <= 9). $1 à $9
	  permettent d'accéder aux parties regroupées (entre
	  parenthèses) du modèle, issues de la RewriteRule
	  concernée par le jeu de conditions RewriteCond
	  courant. $0 donne accès à l'ensemble de la chaîne
	  correspondant au modèle.
      • 
        
    • 
          Références arrières de condition de réécriture
	   : ce sont des références arrières de la forme
	  %N (0 <= N <= 9). %1 à %9
	  permettent d'accéder aux parties regroupées (entre
	  parenthèses) du modèle, issues de la dernière
	  condition RewriteCond satisfaite du jeu de conditions RewriteCond
	  courant. %0 donne accès à l'ensemble de la chaîne
	  correspondant au modèle.
      • 
        
    • 
          extensions de table de réécriture :
	  ce sont des extensions de la forme ${nomTable:clé|défaut}. Voir la href="#mapfunc">documentation sur RewriteMap
	   pour plus de détails.
        
      • 
        
    • 
          Variables du serveur :
	  ce sont des variables de la forme
	  %{ NAME_OF_VARIABLE },
            où NOM_DE_VARIABLE peut contenir une chaîne issue
	    de la liste suivante :

      SERVER_NAME et SERVER_PORT dépendent respectivement
		des valeurs des directives UseCanonicalName et UseCanonicalPhysicalPort.
      

		
      Parmi les variables
		spécifiques à mod_rewrite, ou trouve les suivantes :
      
        
                
      
                  
      API_VERSION
      

                  
      C'est la version de l'API des modules Apache httpd
		  (l'interface interne entre le serveur et les modules)
		  pour la construction courante de httpd, telle qu'elle
		  est définie dans include/ap_mmn.h. La version de l'API
		  des modules correspond à la version du serveur Apache
		  httpd
		  utilisé (par exemple, pour la version 1.3.14 d'Apache
		  httpd,
		  il s'agit de la version 19990320:10), mais intéresse
		  principalement les auteurs de modules.
      

                  
      CONN_REMOTE_ADDR
      

		  
      A partir de la version 2.4.8 : l'adresse IP distante de
		  la connexion (voir le module
		  mod_remoteip).
      

		  
      HTTPS
      

                  
      Contient le texte "on" si la connexion
		  utilise SSL/TLS, "off" dans le cas contraire
		  (Cette variable peut être utilisée sans problème, que
		  mod_ssl soit chargé ou non).
      

		  
      IS_SUBREQ
      

                  
      Contient le texte "true" si la requête en cours
		  de traitement est une sous-requête, "false" dans le
		  cas contraire. Une sous-requête est générée quand un
		  module a besoin de se référer à des fichiers ou URIs
		  addidionnels pour pouvoir mener à bien sa tâche.
      

		  
      REMOTE_ADDR
      
                  
      L'adresse IP de l'hôte distant (se référer au
		  module mod_remoteip).
      

                  
      REQUEST_FILENAME
      

                  
      Le chemin complet local au système de fichiers
		  du fichier ou du script correspondant
		  à la requête, s'il a déjà été déterminé par le serveur
		  au moment où on y fait référence. Dans le cas
		  contraire, et en particulier dans le cas d'un serveur
		  virtuel, REQUEST_FILENAME contient la
		  valeur de REQUEST_URI. En fonction de la
		  valeur de la directive AcceptPathInfo, le serveur
		  peut n'utiliser que certains éléments de tête du
		  REQUEST_URI pour déterminer à quel
		  fichier correspond la requête.
      

		  
      REQUEST_SCHEME
      

                  
      Contient le protocole de la requête (en général
		  "http" ou "https"). La valeur peut être modifiée par
		  la directive ServerName.
      

		  
      REQUEST_URI
      

		  
      La partie chemin de l'URI de la requête, comme
		  "/index.html". Ceci exclut en particulier la chaîne de
		  paramètres de la requête qui est contenue dans la
		  variable QUERY_STRING.
      

                  
      THE_REQUEST
      

                  
      La ligne de requête HTTP complète envoyée par le
		  navigateur au serveur (par exemple, "GET
                  /index.html HTTP/1.1"), à l'exclusion de tout
		  en-tête ajouté par le navigateur. Cette
		  valeur n'a pas été déséchappée (décodée), à la
		  différence de la plupart des variables suivantes.
      
                
      

        
      • 
      
    

      
    Si la chaîne_de_test contient la valeur spéciale
      expr, expression_de_comparaison sera traité
      en tant qu'expression rationnelle de type ap_expr. Si des en-têtes HTTP sont
      référencés dans l'expression rationnelle, et si le drapeau
      novary n'est pas activé, ils seront ajoutés à
      l'en-tête Vary.
    

      
    Autres points à connaître ::
    
      
      
        
    1. 
        
      Les variables SCRIPT_FILENAME et
	REQUEST_FILENAME contiennent toutes deux la valeur
	du champ filename de la
	structure interne request_recdu serveur HTTP Apache.
	Le premier nom correspond au nom de variable bien connu CGI,
	alors que le second est l'équivalent de REQUEST_URI (qui
	contient la valeur du champ uri de
	request_rec).
      
        
      Si une substitution intervient et si la réécriture se
	poursuit, la valeur des deux variables sera mise à jour en
	conséquence.
      
        
      Dans le contexte du serveur principal (c'est à dire avant que
	la requête ne soit mise en correspondance avec le système de
	fichiers), SCRIPT_FILENAME et REQUEST_FILENAME  ne peuvent pas
	contenir le chemin entier dans le système de fichiers local car
	ce chemin b'est pas connu à ce stade du traitement. Dans ce cas,
	les deux variables contiendront la valeur de REQUEST_URI. Pour
	obtenir le chemin complet de la requête dans le système de
	fichiers local dans le contexte du serveur principal, utilisez une
	référence avant à base d'URL
	%{LA-U:REQUEST_FILENAME} pour déterminer la valeur
	finale de REQUEST_FILENAME.
      2. 


        
    2. 
	%{ENV:variable}, où variable peut
	correspondre à une variable d'environnement quelconque.
      3. 
	
    3. 
        %{ENV:variable} est aussi disponible, où
	variable peut correspondre à toute variable
	d'environnement. Peut être consulté via des structures internes
	d'Apache httpd et (si on ne les trouve pas ici) via la fonction
	getenv() à partir du processus du serveur Apache
	httpd.
      4. 

        
    4. Que mod_ssl soit chargé ou non, on peut
	utiliser %{SSL:variable}, où variable
	peut être remplacé par le nom d'une
	variable
	d'environnement SSL . Si mod_ssl n'est pas
	chargé, cette variable contiendra toujours une chaîne vide.
	Exemple : %{SSL:SSL_CIPHER_USEKEYSIZE} pourra
	contenir la valeur 128. Ces variables sont
	disponibles même si l'option StdEnvVars de la
	directive SSLOptions n'a
	pas été définie.
      5. 

	
    5. 
        On peut utiliser %{HTTP:en-tête}, où
	en-tête peut correspondre à tout nom d'en-tête MIME
	HTTP, pour extraire la valeur d'un en-tête envoyé dans la
	requête HTTP. Par exemple, %{HTTP:Proxy-Connection}
	contiendra la valeur de l'en-tête HTTP
	"Proxy-Connection:".
	Si on utilise un en-tête HTTP
	dans une condition, et si cette condition est évaluée à
	vrai pour la requête, cet en-tête sera ajouté à l'en-tête Vary de
	la réponse. Il ne le sera pas si la condition est évaluée à
	faux. L'ajout de l'en-tête HTTP à l'en-tête Vary
	est nécessaire à une mise en cache appropriée.
	
      Il faut garder à l'esprit que les conditions suivent une
	logique de cout-circuit si le drapeau
	'ornext|OR' est utilisé, et que de
	ce fait, certaines d'entre elles ne seront pas évaluées.
      
	
      6. 

        
    6. A des fins de référence avant, on peut utiliser,
	%{LA-U:variable}, qui
	permet d'effectuer une sous-requête interne à base d'URL, afin
	de déterminer la valeur finale de variable. Ceci permet
	d'accéder à la valeur d'une variable pour la réécriture inconnue
	à ce stade du traitement, mais qui sera définie au
	cours d'une phase ultérieure.
	
      Par exemple, pour effectuer une réécriture dépendant de la
	variable REMOTE_USER dans le contexte du serveur
	principal (fichier httpd.conf), vous devez utiliser
	%{LA-U:REMOTE_USER} - cette variable est définie
	par la phase d'autorisation qui intervient après la
	phase de traduction d'URL (pendant laquelle mod_rewrite
	opère).
      
        
      Par contre, comme mod_rewrite implémente son contexte de
	répertoire (fichier .htaccess) via la phase Fixup
	de l'API, et comme la phase d'autorisation intervient
	avant cette dernière, vous pouvez vous contenter
	d'utiliser %{REMOTE_USER} dans ce contexte.
      7. 

        
    7. 
        %{LA-F:variable} peut être utilisée pour effectuer
	une sous-requête interne (basée sur le nom de fichier), afin de
	déterminer la valeur finale de variable. La plupart du
	temps, elle est identique à LA-U (voir ci-dessus).
      8. 
      
    


      
    expression_de_comparaison est une expression
      rationnelle qui est appliquée à l'instance actuelle de
      chaîne_de_test. chaîne_de_test est d'abord
      évaluée, puis comparée à
      l'expression_de_comparaison.
    

      
    expression_de_comparaison est en général une
      expression rationnelle compatible perl, mais vous
      disposez des syntaxes supplémentaires suivantes pour effectuer
      d'autres tests utiles sur chaîne_de_test :
      
    

      
      
        
    1. Vous pouvez préfixer l'expression avec un caractère
	'!' (point d'exclamation) pour inverser le résultat
	de la condition, quelle que soit l'expression de
	comparaison utilisée.
      2. 

        
    2. Vous pouvez effectuer des comparaisons lexicographiques de
	chaînes	:

         
      
            
      <expression
      
	    
      inférieur au sens lexicographique
      
	    Traite l'expression comme une chaîne de
	    caractères et la compare lexicographiquement à
	    chaîne_de_test. La condition est satisfaite si
	    chaîne_de_test est inférieure au sens
	    lexicographique à l'expression.
      

            
      >expression
      
	    
      supérieur au sens lexicographique
      
	    Traite l'expression comme une chaîne de
	    caractères et la compare lexicographiquement à
	    chaîne_de_test. La condition est satisfaite si
	    chaîne_de_test est supérieure au sens
	    lexicographique à l'expression.
      

            
      =expression
      
	    
      égal au sens lexicographique
      
	    Traite l'expression comme une chaîne de
	    caractères et la compare lexicographiquement à
	    chaîne_de_test. La condition est satisfaite si
	    chaîne_de_test est égale au sens
	    lexicographique à l'expression (les deux chaînes
	    sont exactement identiques, caractère pour caractère). Si
	    expression est "" (deux guillemets),
	    chaîne_de_test est comparée à la
	    chaîne vide.
      

	    
      <=expression de comparaison
      
	    
      inférieur ou égal à au sens lexicographique
      
            Considère l'expression_de_comparaison comme une
	    chaîne de caractères et la compare au sens lexicographique à
	    la chaîne_de_test. Vrai si chaîne_de_test
	    précède lexicographiquement expression_de_comparaison, ou est
	    égale à expression_de_comparaison (les deux chaînes
	    sont identiques, caractère pour caractère).
      

            
      >=expression de comparaison
      
	    
      supérieur ou égal à au sens lexicographique
      
            Considère l'expression_de_comparaison comme une
	    chaîne de caractères et la compare au sens lexicographique à
	    la chaîne_de_test. Vrai si chaîne_de_test
	    suit lexicographiquement expression_de_comparaison, ou est
	    égale à expression_de_comparaison (les deux chaînes
	    sont identiques, caractère pour caractère).
      
        
      
	
      Note
      
        L'opérateur de comparaison de chaînes fait partie des arguments de la
	CondPattern et doit par conséquent se trouver entre les
	guillemets s'ils sont présents. Exemple :
	        
        
      RewriteCond %{HTTP_USER_AGENT} "=This Robot/1.0"
      

        
      

	
      3. 

        
    3. 
          Vous pouvez effectuer des comparaisons d'entiers :
          
      

            
      -eq
      
	    
      est numériquement égal à
      
            La chaîne_de_test est considérée comme un entier,
	    et est comparée numériquement à l'expression de
	    comparaison. Vrai si les deux expressions sont
	    numériquement égales.
      

            
      -ge
      
	    
      est numériquement supérieur ou égal à
      
            La chaîne_de_test est considérée comme un entier,
	    et est comparée numériquement à l'expression de
	    comparaison. Vrai si chaîne_de_test est
	    numériquement supérieure ou égale à
	    expression_de_comparaison.
      

             
      -gt
      
	     
      est numériquement supérieur à
      
            La chaîne_de_test est considérée comme un entier,
	    et est comparée numériquement à l'expression de
	    comparaison. Vrai si chaîne_de_test est
	    numériquement
	    supérieure à expression_de_comparaison.
      

            
      -le
      
	    
      est numériquement inférieur ou égal à
      
            La chaîne_de_test est considérée comme un entier,
	    et est comparée numériquement à l'expression de
	    comparaison. Vrai si chaîne_de_test est
	    numériquement
	    inférieure ou égale à expression_de_comparaison.
	    Attention à la confusion avec le drapeau -l
	    en utilisant la variante the -L ou
	    -h.
      

             
      -lt
      
	     
      est numériquement inférieur à
      
            La chaîne_de_test est considérée comme un entier,
	    et est comparée numériquement à l'expression de
	    comparaison. Vrai si chaîne_de_test est
	    numériquement
	    inférieure à expression_de_comparaison.
	    Attention à la confusion avec le drapeau -l
	    en utilisant la variante the -L ou
	    -h.
      

            
      -ne
      
            
      Est numériquement non égal à
      
	     La Chaîne de test est considérée comme un entier et est
	     numériquement comparée à l'expression de comparaison. Vrai
	     si les deux éléments comparés sont numériquement différents.
	     Equivalent à !-eq.
      	    

           
      
        
      4. 

        
    4. Vous pouvez effectuer différents tests sur les attributs de
	fichier :
          
      

            
      -d
      
	    
      est un répertoire
      
	    Traite chaîne_de_test comme un chemin et vérifie
	    s'il existe ou pas, et s'il s'agit d'un répertoire.
      

            
      -f
      
	    
      est un fichier régulier
      
	    Traite chaîne_de_test comme un chemin et vérifie
	    s'il existe ou pas, et s'il s'agit d'un fichier régulier.
      

            
      -F
      
	    
      test de l'existence d'un fichier via une sous-requête
      
	    Vérifie si chaîne_de_test est un fichier valide,
	    accessible à travers tous les contrôles d'accès du serveur
	    actuellement configurés pour ce chemin. C'est une
	    sous-requête interne qui effectue cette vérification - à
	    utiliser avec précautions car les performances du serveur
	    peuvent s'en trouver affectées !
      

	    
      -h
      
	    
      est un lien symbolique, selon la convention bash
      
            Voir -l.
      

            
      -l
      
	    
      est un lien symbolique
      
            Considère la chaîne_de_test comme un chemin et
	    vérifie son existence et si elle est un lien symbolique. On
	    peut aussi utiliser la convention bash -L
	    ou -h lorsqu'il y a risque de confusion
	    avec les tests -lt ou -le.
      

            
      -L
      
	    
      est un lien symbolique, selon la convention bash
      
            Voir -l.
      

            
      -s
      
	    
      est un fichier régulier d'une certaine taille
      
            Considère la chaîne_de_test comme un chemin et
	    vérifie son existence et si elle est un fichier régulier
	    d'une taille supérieure à zéro.
      

            
      -U
      
	    
      test de l'existence d'une
	    URL via une sous-requête
      
	    Vérifie si chaîne_de_test est une URL valide,
	    accessible à travers tous les contrôles d'accès du serveur
	    actuellement configurés pour ce chemin. C'est une
	    sous-requête interne qui effectue cette vérification - à
	    utiliser avec précautions car les performances du serveur
	    peuvent s'en trouver affectées !
      
	    
      Ce drapeau ne renvoie que des informations
	    concernant le contrôle d'accès, l'authentification et
	    l'autorisation. Il ne renvoie pas d'informations
	    concernant le code d'état que le gestionnaire configuré
	    (static file, CGI, proxy, etc...) aurait, quant à lui,
	    retourné.
      

	  
      -x
      
	  
      a l'attribut d'exécution positionné
      
            Considère la chaîne_de_test comme un chemin et
	    vérifie son existence et si elle a son attribut d'exécution
	    positionné. Ce positionnement est déterminé en fonction de
	    l'OS sous-jacent.
      

	    
      

	    Par exemple:

        
      RewriteCond /var/www/%{REQUEST_URI} !-f
RewriteRule ^(.+) /other/archive/$1 [R]
      


        
      5. 

	
    5. 
           
      Si la chaîne_de_test contient la valeur spéciale
	   expr, la chaîne de comparaison sera
	   traitée en tant qu'expression rationnelle de type ap_expr.
      

	   
      
            Dans l'exemple ci-dessous, on utilise -strmatch
	    pour comparer le REFERER avec le nom d'hôte du
	    site afin de bloquer le hotlinking (référencement direct)
	    non désiré.
           
      

           
                 RewriteCond expr "! %{HTTP_REFERER} -strmatch '*://%{HTTP_HOST}/*'"
           RewriteRule "^/images" "-" [F]
      

        
      6. 
    
    

	
    Vous pouvez aussi définir certains drapeaux pour
	l'expression_de_comparaison en ajoutant ces
	[drapeaux]
	comme troisième argument de la directive
	RewriteCond, où drapeaux est un
	sous-ensemble séparé par des virgules des drapeaux suivants :
    

      
      
        
    • 'nocase|NC'
	(no case)
      
	Rend le test insensible à la casse - il n'est pas fait de
	distinction entre majuscules et minuscules, à la fois dans le
	développement de chaîne_de_test et dans
	expression_de_comparaison. Ce drapeau n'est pris en
	compte que lors d'une comparaison entre chaîne_de_test
	et expression_de_comparaison. Il ne l'est pas pour les
	vérification par sous-requêtes ou sur le système de
	fichiers.
      • 

        
    • 
          'ornext|OR'
	  (ou condition suivante)
      
	  Permet de chaîner les conditions de règles avec un OU au
	  lieu du AND implicite. Exemple typique :


      RewriteCond "%{REMOTE_HOST}"  "^host1"  [OR]
RewriteCond "%{REMOTE_HOST}"  "^host2"  [OR]
RewriteCond "%{REMOTE_HOST}"  "^host3"
RewriteRule ...règles concernant tous ces hôtes...
      


          Sans ce drapeau, les paires
	  condition/règle devraient être écrites trois fois.
        
      • 

        
    • 'novary|NV'
	(no vary)
      
	Si la condition contient un en-tête HTTP, ce drapeau empêche
	ce dernier d'être ajouté à l'en-tête Vary de la réponse. 
      
	L'utilisation de ce drapeau peut provoquer une mise en cache
	incorrecte de la réponse, si la représentation de cette réponse
	varie avec la valeur de l'en-tête considéré. Ce drapeau ne
	devrait donc être utilisé que si l'on maîtrise parfaitement le
	fonctionnement de l'en-tête Vary.
        
      • 
      
    
      

      
    Exemple :
    

       
    Pour réécrire la page d'accueil d'un site en fonction de
       l'en-tête ``User-Agent:'' de la requête, vous
       pouvez utiliser ce qui suit : 
    


    RewriteCond  "%{HTTP_USER_AGENT}"  "(iPhone|Blackberry|Android)"
RewriteRule  "^/$"               "/homepage.mobile.html"  [L]

RewriteRule  "^/$"                 "/homepage.std.html"  [L]
    


        
    Explications : si vous utilisez un navigateur
	qui s'identifie comme un
	navigateur de plateforme mobile (notez que l'exemple est
	incomplet car il existe de nombreuses autres plateformes
	mobiles), c'est la version pour mobile de la page d'accueil qui
	sera renvoyée. Dans le cas contraire, ce sera la page d'accueil
	standard.

    Directive RewriteEngine
    

    

    Description:Active ou désactive l'exécution du
moteur de réécriture
    

    Syntaxe:RewriteEngine on|off
    

    Défaut:RewriteEngine off
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_rewrite
    

    

      
    La directive RewriteEngine active ou
      désactive l'exécution du moteur de réécriture. Si sa valeur est
      off, ce module n'exécutera aucun traitement et ne
      mettra pas à jour les variables d'environnement
      SCRIPT_URx.
    

      
    Plutôt que de commenter toutes les directives RewriteRule, il est préférable
      d'utiliser cette directive si l'on souhaite désactiver les
      règles de réécriture dans un contexte particulier.
    

      
    Notez que les  hôtes virtuels n'héritent pas des
      configurations de réécriture. Ceci implique que vous devez
      insérer une directive RewriteEngine on dans chaque
      hôte virtuel pour lequel vous souhaitez utiliser des règles
      de réécriture.
    

      
    Les directives RewriteMap du type
      prg ne sont pas prises en compte au cours de
      l'initialisation du serveur si elle ont été définies dans un
      contexte où la directive RewriteEngine n'a
      pas été définie à on.

    Directive RewriteMap
    

    

    Description:Définit une fonction de mise en correspondance pour la
recherche de mots-clés
    

    Syntaxe:RewriteMap MapName MapType:MapSource [MapTypeOptions]

    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_rewrite
    

    Compatibilité:Le troisième paramètre, MapTypeOptions, est disponible à partir
de la version 2.4.29 du serveur HTTP Apache
    

    
      
    La directive RewriteMap définit une
      Table de correspondance pour la réécriture que les
      fonctions de mise en correspondance
      peuvent utiliser dans les chaînes de substitution des règles
      pour insérer/substituer des champs en recherchant des mots-clés.
      La source utilisée pour cette recherche peut être de plusieurs
      types.
    

      
    MapName est le nom de la table de correspondance
      et servira à spécifier une fonction de mise en correspondance
      pour les chaînes de substitution d'une règle de réécriture selon
      une des constructions suivantes :
    

      
    
        ${ MapName :
        mot-clé }
    
         ${ MapName :
        mot-clé | valeur par défaut
        }    
      
    

      
    Lorsqu'une telle construction est rencontrée, la table de
      correspondance MapName est consultée
      et la clé mot-clé recherchée. Si la clé est trouvée, la
      construction est remplacée par
      la valeur de remplacement. Si la clé n'est pas trouvée,
      elle est remplacée par la valeur par défaut, ou par une
      chaîne vide si aucune valeur par défaut n'est
      spécifiée. La valeur vide se comporte comme si la
      clé était absente ; il est donc impossible de distinguer une
      valeur vide d'une absence de clé.
    

      
    Par exemple, vous pouvez définir une directive
      RewriteMap comme suit 
    

      
    RewriteMap map-exemple "txt:/chemin/vers/fichier/map.txt"
    


      
    Vous pourrez ensuite utiliser cette table dans une
      directive RewriteRule comme suit :
    

      
    RewriteRule "^/ex/(.*)" "${map-exemple:$1}"
    


      
    La signification de l'argument MapTypeOptions dépend du MapType
      spécifié. Veuillez vous référer au document Utiliser RewriteMap pour
      plus de détails.

    Directive RewriteOptions
    

    

    Description:Configure certaines options spéciales
pour le moteur de réécriture
    

    Syntaxe:RewriteOptions Options
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_rewrite
    

    

      
    La directive RewriteOptions définit
      certaines options spéciales pour la configuration au niveau du
      serveur ou du répertoire. La chaîne de caractères Option
      ne peut actuellement prendre qu'une des valeurs suivantes :
    

      
    
      
    Inherit
    
      
    

      
    Ceci force la configuration locale à hériter de la
      configuration du niveau supérieur. Dans le contexte des hôtes
      virtuels, cela signifie que les correspondances, conditions et
      règles du serveur principal sont héritées. Dans le contexte des
      répertoires, cela signifie que les conditions et règles de la
      configuration .htaccess ou les sections <Directory> du répertoire
      parent sont héritées. Les règles héritées sont virtuellement
      copiées dans la section où cette directive est utilisée. Si elles
      sont utilisées avec des règles locales, les règles héritées sont
      placées après ces dernières. La place de cette directive - avant
      ou après les règles locales - n'a aucune influence sur ce
      comportement. Si des règles locales ont forcé l'arrêt de la
      réécriture, les règles héritées ne seront pas traitées.
    

      
    
      Les règles héritées du niveau parent sont appliquées
      after après les règles spécifiées dans le niveau
      enfant.
      
    
      
    

      
    InheritBefore
    
      
    
      
    Même effet que l'option Inherit ci-dessus, mais
      les règles spécifiées dans le niveau parent s'appliquent
      avant les règles spécifiées dans le niveau
      enfant.
    
      Disponible depuis la version 2.3.10 du serveur HTTP Apache.
    
      
    

      
    InheritDown
    
      
    

      
    Si cette option est activée, toutes les configurations enfants
      hériteront de la configuration courante. Il en est de même si l'on
      spécifie RewriteOptions Inherit dans toutes les
      configurations enfants. Voir l'option Inherit pour
      plus de détails à propos de la manière dont les relations
      parent-enfants sont traitées.
    
      Cette option est disponible à partir
      de la version 2.4.8 du serveur HTTP Apache.
    
      
    

      
    InheritDownBefore
    
      
    

      
    L'effet de cette option est équivalent à celui de l'option
      InheritDown ci-dessus, mais les règles de la
      configuration parente s'appliquent avant toute
      règle de la configuration enfant.
    
      Cette option est disponible à partir
      de la version 2.4.8 du serveur HTTP Apache.
    
      
    

      
    IgnoreInherit
    
      
    

      
    Si cette option est activée, les configurations courante et
      enfants ignoreront toute règle héritée d'une configuration parente
      via les options InheritDown ou
      InheritDownBefore.
    
      Cette option est disponible à partir
      de la version 2.4.8 du serveur HTTP Apache.
    
      
    
      
      
    AllowNoSlash
    
      
    
      
    Par défaut, mod_rewrite ignore les URLs qui
      correspondent à un répertoire sur disque, mais ne comportent pas
      de slash final, afin que le module mod_dir
      redirige le client vers l'URL canonique avec un slash final.
    
      
      
    Lorsque la directive DirectorySlash est définie à off, il
      est possible de spécifier l'option AllowNoSlash pour
      s'assurer que les règles de réécriture ne soient plus ignorées.
      Si on le souhaite, cette option permet de faire s'appliquer des
      règles de réécriture qui correspondent à un répertoire sans slash
      final au sein de fichiers .htaccess.
    
      Elle est disponible à
      partir de la version 2.4.0 du serveur HTTP Apache.
    
      
    

      
    AllowAnyURI
    
      
    

      
    A partir de la version 2.2.22 de httpd, lorsqu'une directive RewriteRule se situe dans un
      contexte de serveur virtuel ou de serveur principal,
      mod_rewrite ne traitera les règles de réécriture
      que si l'URI de la requête respecte la syntaxe d'un chemin URL. Ceci permet
      d'éviter certains problèmes de sécurité où des règles
      particulières pourraient permettre  des développements de modèles
      inattendus (voir CVE-2011-3368
      et CVE-2011-4317).
      Pour s'affranchir de la restriction relative à la syntaxe des chemins URL, on peut
      utiliser l'option AllowAnyURI, afin de permettre à
      mod_rewrite d'appliquer le jeu de règles à toute
      chaîne de requête URI, sans vérifier si cette dernière respecte la
      grammaire des chemins URL définie dans la spécification HTTP.
    
      Disponible depuis la version 2.4.3 du serveur HTTP Apache.
    

      
    
      
    Avertissement à propos de la sécurité
     

      
    L'utilisation de cette option rendra le serveur vulnérable à
      certains problèmes de sécurité si les règles de réécritures
      concernées n'ont pas été rédigées avec soin. Il est par conséquent
      fortement recommandé de ne pas utiliser cette
      option. En particulier, prêtez attention aux chaînes en entrée contenant le
      caractère '@', qui peuvent modifier l'interprétation
      de l'URI réécrite, comme indiqué dans les liens ci-dessus.
    
      
    
      
    

      
    MergeBase
    
      
    

      
    Avec cette option, la valeur de la directive RewriteBase est recopiée depuis
      une valeur explicitement définie dans tout sous-répertoire qui ne
      définit pas sa propre directive RewriteBase. Il s'agissait du
      comportement par défaut avec les versions 2.4.0 à 2.4.3, et ce
      drapeau qui permet de retrouver ce comportement est disponible
      depuis la version 2.4.4 du serveur HTTP Apache.
    
      
    

      
    IgnoreContextInfo
    
      
    

      
    Lors d'une
      substitution relative dans un contexte de répertoire (htaccess),
      et si la directive RewriteBase n'a pas été définie,
      ce module utilise des informations en provenance d'une extension
      d'URL et du contexte du système de fichiers pour transformer la
      sustitution relative en URL. Par exemple, les modules
      mod_userdir et mod_alias
      utilisent ces informations de contexte étendu. Disponible à partir de la
      version 2.4.16 du serveur HTTP Apache.
    
      
    

      
    LegacyPrefixDocRoot
    
      
    

      
    Avant la version 2.4.26, si une substitution était une URL absolue qui
      correspondait au serveur virtuel courant, l'URL pouvait être tout d'abord
      réduite à sa partie chemin, puis enfin en chemin local. Comme l'URL peut
      être réduite en chemin local, le chemin doit être préfixé par la
      valeur de la directive DocumentRoot, ce qui permet d'interdire l'accès à
      un fichier tel que /tmp/myfile suite à une requête pour
      http://host/file/myfile avec la RewriteRule suivante :
    
      
    RewriteRule /file/(.*) http://localhost/tmp/$1
    

      
    Cette option permet de restaurer l'ancien comportement lorsqu'un chemin
      local obtenu à partir de la réduction d'une URL n'est pas préfixé par la
      valeur de la directive DocumentRoot. Disponible à partir de la version
      2.4.26 du serveur HTTP Apache.

    Directive RewriteRule
    

    

    Description:Définit les règles pour le moteur de réécriture
    

    Syntaxe:RewriteRule
      Modèle Substitution [drapeaux]
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_rewrite
    

    
      
    La directive RewriteRule est le
      véritable cheval de trait de la réécriture. La directive peut
      apparaître plusieurs fois, chaque instance définissant une
      règle de réécriture particulière. L'ordre dans lequel ces règles
      sont définies est important - il s'agit de l'ordre dans lequel
      les règles seront appliquées au cours du processus de
      réécriture.
    

      
    Modèle est une
      expression rationnelle
      compatible perl. Ce avec quoi ce modèle est comparé dépend de l'endroit où
      la directive RewriteRule est définie.
    


    Qu'est-ce qui est comparé ?
    


      
      
    • Dans un contexte de serveur virtuel VirtualHost, le modèle est tout
      d'abord comparé à la portion de l'URL située entre le nom d'hôte
      éventuellement accompagné du port, et la chaîne de paramètres (par
      exemple "/app1/index.html"). Il s'agit du URL-path décodé de sa valeur "%xx".
      • 

      
    • Dans un contexte de répertoire (sections Directory et fichiers .htaccess), le
      Modèle est comparé avec une partie de chemin ; par exemple une
      requête pour "/app1/index.html" entraînera une comparaison avec
      "app1/index.html" ou "index.html" selon l'endroit où la directive
      RewriteRule est définie.
      

      
      Le chemin où la règle est défini est supprimé du chemin correspondant
      du système de fichiers avant comparaison (jusqu'au slash final compris).
      En conséquence de cette suppression, les règles définies dans
      ce contexte n'effectuent des comparaisons qu'avec la portion du chemin
      du système de fichiers "en dessous" de l'endroit où la règle est définie.
      

      
      Le chemin correspondant actuel du système de fichiers est déterminé par
      des directives telles que DocumentRoot et
      Alias, ou même le résultat de
      substitutions dans des règles RewriteRule précédentes.  
      
      
      
      • 

      
    • Si vous souhaitez faire une comparaison sur le nom
      d'hôte, le port, ou la chaîne de requête, utilisez une
      directive RewriteCond
      comportant respectivement les variables
      %{HTTP_HOST}, %{SERVER_PORT}, ou
      %{QUERY_STRING}.
      • 

    
      

    


    Réécritures dans un contexte de répertoire
    

      

    • L'utilisation du moteur de réécriture dans les
fichiers .htaccess et les sections
<Directory> est un peu plus
complexe.
      • 


    • Pour activer le moteur de réécriture dans ces contextes, vous devez
définir "RewriteEngine On" et
"Options FollowSymLinks". Si l'administrateur a désactivé
la possibilité de modifier l'option FollowSymLinks au
niveau du répertoire d'un utilisateur, vous ne pouvez pas utiliser le
moteur de réécriture. Cette restriction a été instaurée à des fins de
sécurité.
      • 


    • Voir la directive
RewriteBase pour plus de détails à
propos de l'ajout du préfixe après les substitutions relatives.
      • 


    • Si vous souhaitez effectuer une comparaison en prenant en compte
l'intégralité du
chemin de l'URL dans un contexte de répertoire (htaccess), vous devez
utiliser la variable %{REQUEST_URI} dans la directive
RewriteCond.
      • 


    • Le prefixe supprimé se termine toujours par un slash, ce qui
signifie que la comparaison s'effectue avec une chaîne qui ne comporte
jamais de slash de début. Ainsi, un modèle contenant
^/ ne correspondra jamais dans un contexte de répertoire.
      • 


    • Bien que les règles de réécriture soient permises du point de vue de
la syntaxe dans les sections <Location> et <Files> (y compris leurs versions sous forme
d'expression rationnelle), elles n'y sont pas prises en compte, et
n'y sont à priori d'aucune utilité. Les substitutions
relatives sont une fonctionnalité qui n'est, elle non-plus pas supportée
dans ce genre de contexte.
      • 


    • Les blocs If suivent les règles
du contexte de répertoire.
      • 


    • Par défaut, mod_rewrite écrase les règles précédentes au sein de sections combinées appartenant au même
contexte. Pour modifier ce comportement, on peut utiliser la directive
RewriteOptions pour définir par exemple
l'option Inherit.
      • 


    • La directive RewriteOptions permet
aussi de contrôler le comportement des sections définies au même niveau
d'imbrication dans la configuration. Dans l'exemple suivant, par défaut seule la
règle RewriteRules définie dans le second bloc If est prise en compte car celle définie dans le
premier bloc est écrasée. Définir RewriteOptions Inherit force mod_rewrite à combiner
les deux sections en prenant en compte les deux règles et pas seulement la
dernière.
      • 

    

    <If "true">
  # Sans RewriteOptions Inherit, cette règle est écrasée par celle de la section
  # suivante et aucune redirection ne sera effectuée pour les URIs contenant
  # 'foo'
  RewriteRule foo http://example.com/foo [R]
</If>
<If "true">
  RewriteRule bar http://example.com/bar [R]
</If>
    

    

    

	
    Pour quelques conseils à propos des expressions rationnelles, voir le
	document Introduction à
	mod_rewrite.
    

      
    Dans mod_rewrite, on peut aussi utiliser le caractère
      NOT ('!') comme préfixe de modèle. Ceci vous permet
      d'inverser la signification d'un modèle, soit pour dire
      ``si l'URL considérée ne correspond PAS à
      ce modèle''. Le caractère NON peut donc être utilisé à
      titre exceptionnel, lorsqu'il est plus simple d'effectuer une
      comparaison avec le modèle inversé, ou dans la dernière règle
      par défaut.
    


    Note
    
Si vous utilisez le caractère NON pour inverser la signification d'un
modèle, vous ne pouvez pas inclure de parties génériques groupées dans
le modèle. Ceci est dû au fait que, lorsque le modèle ne correspond
pas (autrement dit, sa négation correspond), les groupes sont vides.
Ainsi, si vous utilisez des modèles inversés, vous ne pouvez
pas vous référer aux groupes par $N dans la chaîne de
substitution !

    

      
    Dans une règle de réécriture,
      Substitution est la chaîne
      de caractères qui remplace le chemin de l'URL original qui
      correspondait au Modèle. Substitution peut
      être :
    

      
    

        
    un chemin du système de fichiers
    

        
    Il indique alors la localisation dans le système de
	fichiers de la ressource qui doit être envoyée au
	client. Les substitutions ne sont traitées en tant que chemins du
	système de fichiers que si la règle est configurée dans un
	contexte de serveur (serveur virtuel), et si le premier
	composant du chemin dans la substitution existe dans le système
	de fichiers.
    

        
    chemin d'URL
    

        
    Un chemin relatif à la valeur de DocumentRoot vers la ressource qui
	doit être servie. Notez que mod_rewrite
	essaie de deviner si vous avez spécifié un chemin du système
	de fichiers ou un chemin d'URL en vérifiant si la première
	partie du chemin existe à la racine du système de fichiers.
	Par exemple, si vous avez spécifié comme chaîne de
	Substitution /www/file.html, cette
	dernière sera traitée comme un chemin d'URL à moins
	qu'un répertoire nommé www n'existe à la racine
	de votre système de fichiers (ou dans le cas d'une
	réécriture au sein d'un fichier .htaccess,
	relativement à la racine des documents), auquel cas la chaîne de
	substitution sera traitée comme un chemin du système de
	fichiers. Si vous désirez que d'autres directives de
	correspondance d'URL (comme la directive Alias) soient appliquées au
	chemin d'URL résultant, utilisez le drapeau [PT]
	comme décrit ci-dessous.
    

        
    URL absolue
    

        
    Si une URL absolue est spécifiée,
	mod_rewrite vérifie si le nom d'hôte
	correspond à celui de l'hôte local. Si c'est le cas, le
	protocole et le nom d'hôte sont supprimés, et ce qui reste est
	traité comme un chemin d'URL. Dans le cas contraire, une
	redirection externe vers l'URL indiquée est effectuée. Pour
	forcer une redirection externe vers l'hôte local, voir le
	drapeau [R] ci-dessous.
    

        
    - (tiret)
    

        
    Un tiret indique qu'aucune substitution ne doit être
	effectuée (le chemin considéré est transmis sans changement).
	Ceci est utile quand un drapeau doit être appliqué sans
	modifier le chemin (voir ci-dessous).
    

      
    

      
    En plus du texte, la chaîne Substitution peut
      comporter :
    

      
      
        
    1. des références arrières ($N) vers le modèle
	d'une directive RewriteRule
      2. 

        
    2. des références arrières (%N) vers le dernier
	modèle d'une directive RewriteCond qui correspondait
      3. 

        
    3. des variables du serveur comme dans les chaînes de test de
	condition d'une règle (%{VARNAME})
      4. 

        
    4. des appels de
	fonctions de comparaison
	(${nom correspondance:clé|défaut})
      5. 
      
    

      
    Les références arrières sont des identificateurs de la forme
      $N (N=0..9), qui
      seront remplacés par le contenu du Nème groupe
      du Modèle qui correspondait. Les variables du serveur
      sont les mêmes que dans la Chaîne_de_test d'une
      directive RewriteCond. Les
      fonctions de comparaison sont issues de la directive RewriteMap dans la
      section de laquelle elles sont décrites. Ces trois types de
      variables sont évaluées dans l'ordre ci-dessus.
    

       
    Chaque règle de réécriture s'applique au résultat de la règle
       précédente, selon l'ordre dans lequel elles ont été définies dans
       le fichier de configuration. Le chemin de l'URL ou du système de fichier (voir
       ci-dessus Qu'est-ce qui est
       comparé ?) est intégralement
      remplacée par la chaîne de Substitution et le
      processus de réécriture se poursuit jusqu'à ce que toutes les
      règles aient été appliquées, ou qu'il soit explicitement stoppé
      par un drapeau L,
      ou par un autre drapeau qui implique un arrêt immédiat, comme
      END ou
      F.
    

     
    Modifier la chaîne de requête
    
      
    Par défaut, la chaîne de requête est transmise sans
      modification. Vous pouvez cependant créer dans la chaîne de
      substitution des URLs dont une partie constitue une chaîne de
      requête. Pour cela, ajoutez simplement un point d'interrogation
      dans la chaîne de substitution pour indiquer que le texte qui
      suit doit être réinjecté dans la chaîne de requête. Pour
      supprimer une chaîne de requête, terminez simplement la chaîne de
      substitution par un point d'interrogation. Pour combiner les
      nouvelles chaînes de requête avec les anciennes, utilisez le
      drapeau [QSA].
    
     
    


      
    En outre, vous pouvez spécifier des actions spéciales à effectuer en ajoutant
      des
      [drapeaux]
      comme troisième argument de la directive
      RewriteRule. Séparés par des virgules au sein d'une
      liste encadrée par des crochets, les drapeaux peuvent
      être choisis dans la table suivante. Vous trouverez plus de
      détails, et des exemples pour chaque drapeau dans le document à propos des drapeaux de
      réécriture.
    

      
    Drapeaux et syntaxe
        Fonction
    
    

    
        B

	d'appliquer la transformation. détails ...
    
    

    
        backrefnoplus|BNP
        Avec ce drapeau, si les références arrières sont échappées,
	les espaces seront échappés en %20 au lieu de +. Ceci s'avère
	utile lorsqu'une référence arrière est utilisée dans la partie
	chemin, et non dans la chaîne de paramètres de la requête ;
	pour plus de détails, voir ici.
    
    

            
	chain|C
        La règle est chaînée avec la règle suivante. Si la règle

    Développement du répertoire home
    

     Quand la chaîne de substitution commence par quelque chose comme
"/~user" (de manière explicite ou par références arrières), mod_rewrite
développe le répertoire home sans tenir compte de la présence ou de la
configuration du module mod_userdir.
    


     Ce développement n'est pas effectué si le drapeau PT est
utilisé dans la directive RewriteRule

    Apache Module mod_authn_core

    Description:Core Authentication
    

    Status:Base

    Source File:mod_authn_core.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    

    
    This module provides core authentication capabilities to
    allow or deny access to portions of the web site.
    mod_authn_core provides directives that are
    common to all authentication providers.
    

    


    top
    

    

    Creating Authentication Provider Aliases
    

    
    Extended authentication providers can be created
    within the configuration file and assigned an alias name.  The alias
    providers can then be referenced through the directives
    AuthBasicProvider or
    AuthDigestProvider in
    the same way as a base authentication provider.  Besides the ability
    to create and alias an extended provider, it also allows the same
    extended authentication provider to be reference by multiple
    locations.
    

    
    Examples
    

        
    This example checks for passwords in two different text
        files.
    

        
    Checking multiple text password files
    # Check here first
<AuthnProviderAlias file file1>
    AuthUserFile "/www/conf/passwords1"
</AuthnProviderAlias>

# Then check here
<AuthnProviderAlias file file2>   
    AuthUserFile "/www/conf/passwords2"
</AuthnProviderAlias>

<Directory "/var/web/pages/secure">
    AuthBasicProvider file1 file2
    
    AuthType Basic
    AuthName "Protected Area"
    Require valid-user
</Directory>
    

    

        
    The example below creates two different ldap authentication
        provider aliases based on the ldap provider.  This allows
        a single authenticated location to be serviced by multiple ldap
        hosts:
    

        
    Checking multiple LDAP servers
    <AuthnProviderAlias ldap ldap-alias1>
    AuthLDAPBindDN cn=youruser,o=ctx
    AuthLDAPBindPassword yourpassword
    AuthLDAPURL ldap://ldap.host/o=ctx
</AuthnProviderAlias>
<AuthnProviderAlias ldap ldap-other-alias>
    AuthLDAPBindDN cn=yourotheruser,o=dev
    AuthLDAPBindPassword yourotherpassword
    AuthLDAPURL ldap://other.ldap.host/o=dev?cn
</AuthnProviderAlias>

Alias "/secure" "/webpages/secure"
<Directory "/webpages/secure">
    AuthBasicProvider ldap-other-alias  ldap-alias1
    
    AuthType Basic
    AuthName "LDAP Protected Place"
    Require valid-user
    # Note that Require ldap-* would not work here, since the 
    # AuthnProviderAlias does not provide the config to authorization providers
    # that are implemented in the same module as the authentication provider.
</Directory>

    AuthName Directive
    

    

    Description:Authorization realm for use in HTTP
authentication
    

    Syntax:AuthName auth-domain
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authn_core
    

    
    
    This directive sets the name of the authorization realm for a
    directory. This realm is given to the client so that the user
    knows which username and password to send.
    AuthName takes a single argument; if the
    realm name contains spaces, it must be enclosed in quotation
    marks.  It must be accompanied by AuthType and Require directives, and directives such
    as AuthUserFile and
    AuthGroupFile to
    work.
    

   
    For example:
    

   
    AuthName "Top Secret"
    


    
    The string provided for the AuthName is what will
    appear in the password dialog provided by most browsers.

    <AuthnProviderAlias> Directive
    

    

    Description:Enclose a group of directives that represent an
extension of a base authentication provider and referenced by
the specified alias
    

    Syntax:<AuthnProviderAlias baseProvider Alias>
... </AuthnProviderAlias>
    

    Context:server config
    

    Status:Base
    

    Module:mod_authn_core
    

    
    
    <AuthnProviderAlias> and
    </AuthnProviderAlias> are used to enclose a group of
    authentication directives that can be referenced by the alias name
    using one of the directives 
    AuthBasicProvider or 
    AuthDigestProvider.
    

    
    This directive has no affect on authorization, even for modules that
    provide both authentication and authorization.
    


    

    top
    

    AuthType Directive
    

    

    Description:Type of user authentication
    

    Syntax:AuthType None|Basic|Digest|Form
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authn_core
    

    
    
    This directive selects the type of user authentication for a
    directory. The authentication types available are None,
    Basic (implemented by
    mod_auth_basic), Digest
    (implemented by mod_auth_digest), and
    Form (implemented by mod_auth_form).
    

    
    To implement authentication, you must also use the AuthName and Require directives.  In addition, the
    server must have an authentication-provider module such as
    mod_authn_file and an authorization module such
    as mod_authz_user.
    

    
    The authentication type None disables authentication.
    When authentication is enabled, it is normally inherited by each
    subsequent configuration section,
    unless a different authentication type is specified.  If no
    authentication is desired for a subsection of an authenticated
    section, the authentication type None may be used;
    in the following example, clients may access the
    /www/docs/public directory without authenticating:
    

    
    <Directory "/www/docs">
    AuthType Basic
    AuthName Documents
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    Require valid-user
</Directory>

<Directory "/www/docs/public">
    AuthType None
    Require all granted
</Directory>
    


    
    When disabling authentication, note that clients which have
    already authenticated against another portion of the server's document
    tree will typically continue to send authentication HTTP headers
    or cookies with each request, regardless of whether the server
    actually requires authentication for every resource.

    モジュール識別子:proxy_connect_module
    

    ソースファイル:mod_proxy_connect.c
    

    概要
    

    
    本モジュールには mod_proxy が必要です。
    CONNECT HTTP メソッドをサポートします。
    このメソッドは主にプロキシに SSL リクエストを通す
    (訳注: SSLトンネリング)に使われます。
    

    
    CONNECT リクエストを扱えるようにするには
    mod_proxy と mod_proxy_connect
    をサーバに組み込む必要があります。
    

    
    警告
    
      
    安全なサーバにするまでプロキシ機能は有効にしないでください。
      オープンプロキシサーバはあなた自身のネットワークにとっても、
      インターネット全体にとっても危険です。

    Description:UWSGI gateway module for mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_uwsgi_module
    

    Source File:mod_proxy_uwsgi.c
    

    Compatibility:Available in version 2.4.30 and later
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the
    UWSGI protocol.
    

    
    Thus, in order to get the ability of handling the UWSGI protocol,
    mod_proxy and mod_proxy_uwsgi have to
    be present in the server.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.
    
    
    

    

    Support Apache!

    Examples
    
    
    Remember, in order to make the following examples work, you have to
    enable mod_proxy and mod_proxy_uwsgi.
    

    
    Simple gateway
    ProxyPass "/uwsgi-bin/" "uwsgi://localhost:4000/"
    

    

    
    The balanced gateway needs mod_proxy_balancer and
    at least one load balancer algorithm module, such as
    mod_lbmethod_byrequests, in addition to the proxy
    modules listed above.  mod_lbmethod_byrequests is the
    default, and will be used for this example configuration.
    

    
    Balanced gateway
    ProxyPass "/uwsgi-bin/" "balancer://somecluster/"
<Proxy balancer://somecluster>
    BalancerMember uwsgi://localhost:4000
    BalancerMember uwsgi://localhost:4001
</Proxy>

    Sommaire
    


    Ce module ne fournit pas lui-même de directive de configuration. Il
nécessite les services de mod_proxy_balancer, et
fournit la méthode de répartition de charge bytraffic.
    

    


    top
    

    

    Algorithme de répartition en fonction d'un certain
    trafic
    
    
    
    Activé via lbmethod=bytraffic, l'idée directrice de
    ce planificateur est similaire à celle de la méthode reposant sur le
    nombre de requêtes, avec les différences suivantes :
    

    
    lbfactor représente la quantité de trafic, en
    octets, que nous voulons voir traitée par le processus. Il
    s'agit là aussi d'une valeur normalisée représentant la part de
    travail à effectuer par le processus, mais au lieu de se baser sur
    un nombre de requêtes, on prend en compte la quantité de trafic que
    ce processus a traité.
    

    
    Si un répartiteur est configuré comme suit :
    

    
    worker
        a
        b
        c
    

    lbfactor
        1
        2
        1
    

    

    
    Cela signifie que nous souhaitons que b traite 2 fois
    plus d'octets que a ou c. Cela n'entraîne pas
    nécessairement que b va traiter deux fois plus de
    requêtes, mais qu'il va traiter deux fois plus de trafic en termes
    d'entrées/sorties. A cet effet, les tailles de la requête et de sa
    réponse assocciée sont prises en compte par l'algorithme de
    sélection et d'évaluation du trafic.
    

    
    Note : les octets en entrée sont évalués avec la même pondération
    que les octets en sortie.

    Module Apache mod_authz_core
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Autorisation basique
    

    Statut:Base
    

    Identificateur de Module:authz_core_module
    

    Fichier Source:mod_authz_core.c
    

    Compatibilité:Disponible depuis la version 2.3
d'Apache HTTPD
    

    Sommaire
    

    
    Ce module fournit des fonctionnalités d'autorisation basiques
    permettant d'accorder ou refuser l'accès à certaines zones du site
    web aux utilisateurs authentifiés. mod_authz_core
    donne la possibilité d'enregistrer divers fournisseurs
    d'autorisation. Il est en général utilisé avec un module fournisseur
    d'authentification comme mod_authn_file, et un
    module d'autorisation comme mod_authz_user. Il
    permet aussi l'application d'une logique élaborée au déroulement du
    processus d'autorisation.
    

    


    top
    

    

    Conteneurs d'autorisation
    

    
    Les directives de conteneur d'autorisation <RequireAll>,
    <RequireAny> et <RequireNone>
    peuvent être combinées entre elles et avec la directive Require pour confectionner une
    logique d'autorisation complexe.
    

    
    L'exemple ci-dessous illustre la logique d'autorisation suivante.
    Pour pouvoir accéder à la ressource, l'utilisateur doit être
    l'utilisateur superadmin, ou appartenir aux deux
    groupes LDAP admins et Administrateurs et
    soit appartenir au groupe ventes ou avoir
    ventes comme valeur de l'attribut LDAP
    dept. De plus, pour pouvoir accéder à la ressource,
    l'utilisateur ne doit appartenir ni au groupe temps, ni
    au groupe LDAP Employés temporaires.
    

    
    <Directory "/www/mydocs">
    <RequireAll>
        <RequireAny>
            Require user superadmin
            <RequireAll>
            Require group admins
            Require ldap-group "cn=Administrators,o=Airius"
                <RequireAny>
                Require group sales
                Require ldap-attribute dept="sales"
                </RequireAny>
            </RequireAll>
        </RequireAny>
        <RequireNone>
            Require group temps
            Require ldap-group "cn=Temporary Employees,o=Airius"
        </RequireNone>
    </RequireAll>
</Directory>

    Les directives Require
    

  
    Le module mod_authz_core met à disposition des
  fournisseurs d'autorisation génériques utilisables avec la directive
  Require.
    

  
    Require env
    

    
    Le fournisseur env permet de contrôler l'accès au
    serveur en fonction de l'existence d'une variable d'environnement. Lorsque Require
    env env-variable est spécifié, la requête se voit
    autoriser l'accès si la variable d'environnement
    env-variable existe. Le serveur permet de définir
    facilement des variables d'environnement en fonction des
    caractéristiques de la requête du client via les directives fournies
    par le module mod_setenvif. Cette directive Require
    env permet donc de contrôler l'accès en fonction des
    valeurs des en-têtes de la requête HTTP tels que
    User-Agent (type de navigateur), Referer,
    entre autres.
    

    
    SetEnvIf User-Agent "^KnockKnock/2\.0" let_me_in
<Directory "/docroot">
    Require env let_me_in
</Directory>
    


    
    Avec cet exemple, les navigateurs dont la chaîne user-agent
    commence par KnockKnock/2.0 se verront autoriser
    l'accès, alors que tous les autres seront rejetés.
    

    
    Lorsque le serveur cherche un chemin via une sous-requête interne (par exemple la
   recherche d'un DirectoryIndex), ou lorsqu'il génère un
   listing du contenu d'un répertoire via le module
   mod_autoindex, la sous-requête n'hérite pas des
   variables d'environnement spécifiques à la requête. En outre, à cause
   des phases de l'API auxquelles mod_setenvif prend
   part, les directives SetEnvIf ne sont pas évaluées
   séparément dans la sous-requête.
    

  

  
    Require all
    

    
    Le fournisseur all reproduit la fonctionnalité
    précédemment fournie par les directives 'Allow from all' et 'Deny
    from all'. Il accepte un argument dont les deux valeurs possibles
    sont : 'granted' ou 'denied'. Les exemples suivants autorisent ou
    interdisent l'accès à toutes les requêtes.
    

    
    Require all granted
    


    
    Require all denied
    


  

  
    Require method
    

    
    Le fournisseur method permet d'utiliser la méthode
    HTTP dans le processus d'autorisation. Les méthodes GET et HEAD sont
    ici considérées comme équivalentes. La méthode TRACE n'est pas
    supportée par ce fournisseur ; utilisez à la place la directive
    TraceEnable.
    

    
    Dans l'exemple suivant, seules les méthodes GET, HEAD, POST, et
    OPTIONS sont autorisées :
    

    
    Require method GET POST OPTIONS
    


    
    Dans l'exemple suivant, les méthodes GET, HEAD, POST, et OPTIONS
    sont autorisées sans authentification, alors que toutes les autres
    méthodes nécessitent un utilisateur valide :
    

    
    <RequireAny>
     Require method GET POST OPTIONS
     Require valid-user
</RequireAny>
    


  
  
    Require expr
    

  
    Le fournisseur expr permet d'accorder l'autorisation
  d'accès de base en fonction d'expressions arbitraires.
    

    
    Require expr "%{TIME_HOUR} -ge 9 && %{TIME_HOUR} -le 17"
    


    
    <RequireAll>
    Require expr "!(%{QUERY_STRING} =~ /secret/)"
    Require expr "%{REQUEST_URI} in { '/example.cgi', '/other.cgi' }" 
</RequireAll>
    


    
    Require expr "!(%{QUERY_STRING} =~ /secret/) && %{REQUEST_URI} in { '/example.cgi', '/other.cgi' }"
    


    
    La syntaxe de l'expression est décrite dans la documentation de ap_expr. Avant la version 2.4.16, les doubles-quotes
    étaient prohibées
    

    
    Normalement, l'expression est évaluée avant l'authentification.
    Cependant, si l'expression renvoie false et se réfère à la variable
    %{REMOTE_USER}, le processus d'authentification sera
    engagé et l'expression réévaluée.

    Création des alias du fournisseur
d'autorisation
    

    
    Il est possible de créer des fournisseurs d'autorisation étendus
    dans le fichier de configuration et de leur assigner un nom d'alias.
    On peut ensuite utiliser ces fournisseurs aliasés dans une
    directive Require de
    la même manière qu'on le ferait pour des fournisseurs d'autorisation
    de base. En plus de la possibilité de créer et d'aliaser un
    fournisseur étendu, le même fournisseur d'autorisation étendu peut
    être référencé par plusieurs localisations.
    
    

    
    Exemple
    
        
    Dans l'exemple suivant, on crée deux alias de fournisseur
	d'autorisation ldap différents basés sur le fournisseur
	d'autorisation ldap-group. Il est ainsi possible pour un seul
	répertoire de vérifier l'appartenance à un groupe dans plusieurs
	serveurs ldap :
        
    

        
    <AuthzProviderAlias ldap-group ldap-group-alias1 "cn=my-group,o=ctx">
    AuthLDAPBindDN "cn=youruser,o=ctx"
    AuthLDAPBindPassword yourpassword
    AuthLDAPURL "ldap://ldap.host/o=ctx"
</AuthzProviderAlias>

<AuthzProviderAlias ldap-group ldap-group-alias2 "cn=my-other-group,o=dev">
    AuthLDAPBindDN "cn=yourotheruser,o=dev"
    AuthLDAPBindPassword yourotherpassword
    AuthLDAPURL "ldap://other.ldap.host/o=dev?cn"
</AuthzProviderAlias>

Alias "/secure" "/webpages/secure"
<Directory "/webpages/secure">
    Require all granted
    
    AuthBasicProvider file
    
    AuthType Basic
    AuthName LDAP_Protected_Place
    
    #implied OR operation
    Require ldap-group-alias1
    Require ldap-group-alias2
</Directory>

    Directive AuthMerging
    

    

    Description:Définit la manière dont chaque logique d'autorisation des
sections de configuration se combine avec celles des sections de
configuration précédentes.
    

    Syntaxe:AuthMerging Off | And | Or
    

    Défaut:AuthMerging Off
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Base
    

    Module:mod_authz_core
    

    
    
    Lorsque l'autorisation est activée, elle est normalement héritée
    par chaque section de
    configuration suivante, à moins qu'un jeu de directives
    d'autorisations différent ne soit spécifié. Il s'agit du
    comportement par défaut, qui correspond à la définition explicite
    AuthMerging Off.
    

    
    Dans certaines situations cependant, il peut être souhaitable de
    combiner la logique d'autorisation d'une section de configuration
    avec celle de la section précédente lorsque les sections de
    configuration se combinent entre elles. Dans ce cas, deux options
    sont disponibles, And et Or.
    

    
    Lorsqu'une section de configuration contient AuthMerging
    And ou AuthMerging Or, sa logique d'autorisation
    se combine avec celle de la section de configuration qui la précède
    (selon l'ordre général des sections de configuration), et qui
    contient aussi une logique d'autorisation, comme si les deux
    sections étaient concaténées respectivement dans une directive
    <RequireAll> ou <RequireAny>.
    

    
    La définition de la directive
    AuthMerging ne concerne que la section de
    configuration dans laquelle elle apparaît. Dans l'exemple suivant,
    seuls les utilisateurs appartenant au groupe alpha sont
    autorisés à accéder à /www/docs. Les utilisateurs
    appartenant au groupe alpha ou au groupe
    beta sont autorisés à accéder à
    /www/docs/ab. Cependant, la définition implicite à
    Off de la directive AuthMerging
    s'applique à la section de configuration <Directory> concernant le répertoire
    /www/docs/ab/gamma, ce qui implique que les directives
    d'autorisation de cette section l'emportent sur celles des sections
    précédentes. Par voie de conséquence, seuls les utilisateurs
    appartenant au groupe gamma sont autorisés à accéder à
    /www/docs/ab/gamma.
    

    
    <Directory "/www/docs">
    AuthType Basic
    AuthName Documents
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    Require group alpha
</Directory>

<Directory "/www/docs/ab">
    AuthMerging Or
    Require group beta
</Directory>

<Directory "/www/docs/ab/gamma">
    Require group gamma
</Directory>

    Directive <AuthzProviderAlias>
    

    

    Description:Regroupe des directives représentant une extension d'un
fournisseur d'autorisation de base qui pourra être référencée à l'aide
de l'alias spécifié
    

    Syntaxe:<AuthzProviderAlias fournisseur-de-base Alias

... </AuthzProviderAlias>

    

    Contexte:configuration globale

    Module:mod_authz_core
    

    
    
    Les balises <AuthzProviderAlias> et
    </AuthzProviderAlias> permettent de regrouper des
    directives d'autorisation auxquelles on pourra faire référence à
    l'aide de l'alias spécifié dans une directive Require.
    

    
    Si Require-Parameters comporte plusieurs paramètres, la liste
    de ces derniers doit être entourée de guillemets. Dans le cas contraire,
    seul le premier paramètre de la liste sera pris en compte.
    
    
    
    # Dans cet exemple, pour que les deux adresses IP soient prises en compte, elles
# DOIVENT être entourées de guillemets
<AuthzProviderAlias ip reject-ips "XXX.XXX.XXX.XXX YYY.YYY.YYY.YYY">
</AuthzProviderAlias>

    Directive AuthzSendForbiddenOnFailure
    

    

    Description:Envoie '403 FORBIDDEN' au lieu de '401 UNAUTHORIZED' si
l'authentification réussit et si l'autorisation a été refusée.

    

    Syntaxe:AuthzSendForbiddenOnFailure On|Off
    

    Défaut:AuthzSendForbiddenOnFailure Off
    

    Contexte:répertoire, .htaccess
    

    Statut:Base
    

    Module:mod_authz_core
    

    Compatibilité:Disponible depuis la version 2.3.11 d'Apache HTTPD
    

    
    
    Par défaut, si l'authentification réussit, alors que
    l'autorisation est refusée, Apache HTTPD renvoie un code de réponse
    HTTP '401 UNAUTHORIZED'. En général, les navigateurs proposent alors
    une nouvelle fois à l'utilisateur la boîte de dialogue de saisie du
    mot de passe, ce qui n'est pas toujours souhaitable. La directive
    AuthzSendForbiddenOnFailure permet de changer
    le code de réponse en '403 FORBIDDEN'.
    

    
    Avertissement de sécurité
    
    
    La modification de la réponse en cas de refus d'autorisation
    diminue la sécurité du mot de passe, car elle indique à un éventuel
    attaquant que le mot de passe qu'il a saisi était correct.

    Cette directive permet de vérifier si un utilisateur authentifié
    a l'autorisation d'accès accordée pour un certain fournisseur
    d'autorisation et en tenant compte de certaines restrictions.
    mod_authz_core met à disposition les fournisseurs
    d'autorisation génériques suivants :
    

    
    
      
    Require all granted
    
      
    L'accès est autorisé sans restriction.

    L'accès est systématiquement refusé.
    

      
    Require env env-var [env-var]
      ...
    
      
    L'accès n'est autorisé que si l'une au moins des variables
      d'environnement spécifiées est définie.
    

      
    Require method http-method [http-method]
      ...
    
      
    L'accès n'est autorisé que pour les méthodes HTTP spécifiées.
    

      
    Require expr expression 
    
      
    L'accès est autorisé si expression est évalué à
      vrai.
    
    
    

    
    Voici quelques exemples de syntaxes autorisées par
    mod_authz_user, mod_authz_host et

    Tous les utilisateurs valides auront accès à la
      ressource.
    

      
    Require ip 10 172.20 192.168.2
    
      
    Les clients dont les adresses IP font partie des tranches
      spécifiées auront accès à la ressource.
    

      
    Require forward-dns dynamic.example.org
    
      
    Un client dont l'adresse IP est résolue à partir du nom
      dynamic.example.org aura l'autorisation d'accès.
      
    

    
        

    
    D'autres modules d'autorisation comme
    mod_authnz_ldap, mod_authz_dbm,
    mod_authz_dbd,
    mod_authz_owner et mod_ssl
    implémentent des options de la directive Require.
    

    
    Pour qu'une configuration d'authentification et d'autorisation
    fonctionne correctement, la directive Require
    doit être accompagnée dans la plupart des cas de directives AuthName, AuthType et AuthBasicProvider ou AuthDigestProvider, ainsi que
    de directives telles que AuthUserFile et AuthGroupFile (pour la
    définition des utilisateurs et des groupes). Exemple :
    

    
    AuthType Basic
AuthName "Restricted Resource"
AuthBasicProvider file
AuthUserFile "/web/users"
AuthGroupFile "/web/groups"
Require group admin
    


    
    Les contrôles d'accès appliqués de cette manière sont effectifs
    pour toutes les méthodes. C'est d'ailleurs
    ce que l'on souhaite en général. Si vous voulez n'appliquer
    les contrôles d'accès qu'à certaines méthodes, tout en laissant les
    autres méthodes sans protection, placez la directive
    Require dans une section <Limit>.
    

    
    Le résultat de la directive Require peut
    être inversé en utilisant l'option not. Comme dans le
    cas de l'autre directive d'autorisation inversée <RequireNone>, si la directive
    Require est inversée, elle ne peut qu'échouer
    ou produire un résultat neutre ; elle ne peut donc alors pas
    autoriser une requête de manière indépendante.
    

    
    Dans l'exemple suivant, tous les utilisateurs appartenant aux
    groupes alpha et beta ont l'autorisation
    d'accès, à l'exception de ceux appartenant au groupe
    reject.
    

    
    <Directory "/www/docs">
    <RequireAll>
        Require group alpha beta
        Require not group reject
    </RequireAll>
</Directory>
    


    
    Lorsque plusieurs directives Require sont
    placées dans une même section de
    configuration, et ne se trouvent pas dans une autre directive
    d'autorisation comme <RequireAll>, elles sont implicitement
    contenues dans une directive <RequireAny>. Ainsi, la première directive
    Require qui autorise l'accès à un utilisateur
    autorise l'accès pour l'ensemble de la requête, et les directives
    Require suivantes sont ignorées.
    

    
    Avertissement à propos de la sécurité
    
    
    Prettez une attention particulière aux directives d'autorisation
    définies
    au sein des sections Location
    qui se chevauchent avec des contenus servis depuis le système de
    fichiers. Par défaut, les configurations définies dans ces sections l'emportent sur les
    configurations d'autorisations définies au sein des sections
    Directory et Files sections.
    
    
    La directive AuthMerging permet de contrôler
    la manière selon laquelle les configurations d'autorisations sont
    fusionnées au sein des sections précitées.

    directives d'autorisation dont au moins une doit retourner un
    résultat positif pour que la directive <RequireAny> retourne elle-même un résultat
    positif.
    

    
    Si une ou plusieurs directives contenues dans la directive
    <RequireAny> retournent un
    résultat positif, alors la directive <RequireAny> retourne elle-même un résultat
    positif. Si aucune ne retourne un résultat positif et aucune
    n'échoue, la directive globale retourne un résultat neutre. Dans
    tous les autres cas, elle échoue.
    

    
    Comme les directives d'autorisation inversées sont incapables
    de retourner un résultat positif, elles ne peuvent pas impacter de
    manière significative le résultat d'une directive <RequireAny> (elles pourraient tout au plus
    faire échouer la directive dans le cas où elles échoueraient
    elles-mêmes, et où
    toutes les autres directives retourneraient un résultat neutre).
    C'est pourquoi il n'est pas permis d'utiliser les directives
    d'autorisation inversées dans une directive <RequireAny>.

    Directive <RequireNone>

    positif pour que la directive <RequireNone> n'échoue pas.
    

    
    Si une ou plusieurs directives contenues dans la directive
    <RequireNone> retournent un
    résultat positif, la directive <RequireNone> échouera. Dans tous les
    autres cas, cette dernière retournera un résultat neutre. Ainsi,
    comme pour la directive d'autorisation inversée Require
    not, elle ne peut jamais autoriser une requête de manière
    indépendante car elle ne pourra jamais retourner un résultat
    positif. Par contre, on peut l'utiliser pour restreindre l'ensemble
    des utilisateurs autorisés à accéder à une ressource.
    

    
    Comme les directives d'autorisation inversées sont incapables
    de retourner un résultat positif, elles ne peuvent pas impacter de
    manière significative le résultat d'une directive <RequireNone>.

    Directiva AcceptFilter
    

    

    Descripción:Configura mejoras para un Protocolo de Escucha de Sockets
    

    Sintaxis:AcceptFilter protocol accept_filter
    

    Contexto:server config
    

    Estado:Core
    

    Módulo:core
    

    Compatibilidad:Disponible en Apache httpd 2.1.5 y posteriores.
En Windows desde Apache httpd 2.3.3 y posteriores.
    

    
    
    Esta directiva hace posible mejoras específicas a nivel de sistema operativo
       y a través del tipo de Protocolo para un socket que escucha.
       La premisa básica es que el kernel no envíe un socket al servidor
       hasta que o bien los datos se hayan recibido o bien se haya almacenado
       en el buffer una Respuesta HTTP completa.  
       Actualmente sólo están soportados
       
       Accept Filters sobre FreeBSD, TCP_DEFER_ACCEPT sobre Linux, 
       y AcceptEx() sobre Windows.
    

    
    El uso de none para un argumento desactiva cualquier filtro 
       aceptado para ese protocolo. Esto es útil para protocolos que requieren que un
       servidor envíe datos primeros, tales como ftp: o nntp:
    
    
    AcceptFilter nntp none
    

    
    Los nombres de protocolo por defecto son https para el puerto 443
       y http para todos los demás puertos. Para especificar que se está
       utilizando otro protocolo con un puerto escuchando, añade el argumento protocol
       a la directiva Listen.
    

    
    Sobre FreeBDS los valores por defecto:
    
    
    
        AcceptFilter http httpready 
    
        AcceptFilter https dataready
    
    
    
    
    El filtro httpready almacena en el buffer peticiones HTTP completas
       a nivel de kernel.  Una vez que la petición es recibida, el kernel la envía al servidor. 
       Consulta la página man de
       
       accf_http(9) para más detalles.  Puesto que las peticiones HTTPS
       están encriptadas, sólo se utiliza el filtro
       accf_data(9).
    

    
    Sobre Linux los valores por defecto son:
    
    
    
        AcceptFilter http data 
    
        AcceptFilter https data
    
    

    
    En Linux, TCP_DEFER_ACCEPT no soporta el buffering en peticiones http.
       Cualquier valor además de none habilitará 
       TCP_DEFER_ACCEPT en ese socket. Para más detalles 
       ver la página man de Linux 
       
       tcp(7).
    

    
    Sobre Windows los valores por defecto son:
    
    
    
        AcceptFilter http data 
    
        AcceptFilter https data
    
    

    
    Sobre Windows mpm_winnt interpreta el argumento AcceptFilter para conmutar la API
       AcceptEx(), y no soporta el buffering sobre el protocolo http.  Hay dos valores
       que utilizan la API Windows AcceptEx() y que recuperan sockets de red
       entre conexciones.  data espera hasta que los datos han sido
       transmitidos como se comentaba anteriormente, y el buffer inicial de datos y las
       direcciones de red son recuperadas a partir de una única llamada AcceptEx().
       connect utiliza la API AcceptEx() API, y recupera también
       las direcciones de red, pero a diferencia de none 
       la opción connect no espera a la transmisión inicial de los datos.
    

    
    Sobre Windows, none prefiere accept() antes que AcceptEx()
       y no recuperará sockets entre las conexiones.  Lo que es útil para los adaptadores de
       red con un soporte precario de drivers, así como para algunos proveedores de red
       tales como drivers vpn, o filtros de spam, de virus o de spyware.

    Directiva AcceptPathInfo
    

    

    Descripción:Los recursos aceptan información sobre su ruta
    

    Sintaxis:AcceptPathInfo On|Off|Default
    

    Valor por defecto:AcceptPathInfo Default
    

    Contexto:server config, virtual host, directory, .htaccess
    

    Anula:FileInfo
    

    Estado:Core
    

    Módulo:core
    

    Compatibilidad:Disponible en Apache httpd 2.0.30 y posteriores
    

    

    
    Esta directiva controla si las peticiones que contienen información sobre la ruta
    que sigue un fichero que existe (o un fichero que no existe pero en un directorio que
    sí existe) serán aceptadas o denegadas.  La información de ruta puede estar disponible
    para los scripts en la variable de entorno PATH_INFO.
    

    
    Por ejemplo, asumamos que la ubicación /test/ apunta a
    un directorio que contiene únicamente el fichero
    here.html.  Entonces, las peticiones tanto para
    /test/here.html/more como para
    /test/nothere.html/more recogen
    /more como PATH_INFO.
    

    
    Los tres posibles argumentos para la directiva
    AcceptPathInfo son los siguientes:
    
    
    
    
    Off
    Una petición sólo será aceptada si
    se corresponde con una ruta literal que existe.  Por lo tanto, una petición
    con una información de ruta después del nombre de fichero tal como
    /test/here.html/more en el ejemplo anterior devolverá
    un error 404 NOT FOUND.
    

    
    On
    Una petición será aceptada si una
    ruta principal de acceso se corresponde con un fichero que existe. El ejemplo
    anterior /test/here.html/more será aceptado si
    /test/here.html corresponde a un fichero válido.
    

    
    Default
    La gestión de las peticiones
    con información de ruta está determinada por el controlador responsable de la petición.
    El controlador principal para para ficheros normales rechaza por defecto
    peticiones PATH_INFO. Los controladores que sirven scripts, tales como cgi-script e isapi-handler, normalmente aceptan
    PATH_INFO por defecto.
    
    
    

    
    El objetivo principal de la directiva AcceptPathInfo
    es permitirte sobreescribir la opción del controlador
    de aceptar or rechazar PATH_INFO. Este tipo de sobreescritura se necesita,
    por ejemplo, cuando utilizas un filtro, tal como
    INCLUDES, para generar contenido
    basado en PATH_INFO. El controlador principal normalmente rechazaría
    la petición, de modo que puedes utilizar la siguiente configuración para habilitarla
    como script:
    

    
    
      <Files "mypaths.shtml">
    
      
        Options +Includes
    
        SetOutputFilter INCLUDES
    
        AcceptPathInfo On
    
          
      </Files>

    Directiva AccessFileName
    

    

    Descripción:Nombre del fichero distribuido de configuración
    

    Sintaxis:AccessFileName filename [filename] ...
    

    Valor por defecto:AccessFileName .htaccess
    

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    
    
    Mientras que procesa una petición el servidor busca
    el primer fichero de configuración existente dentro de un listado de nombres en
    cada directorio de la ruta del documento, si los ficheros distribuidos
    de configuración están habilitados para ese
    directorio. Por ejemplo:
    

    
    
      AccessFileName .acl
    
    

    
    antes de servir el documento
    /usr/local/web/index.html, el servidor leerá
    /.acl, /usr/.acl,
    /usr/local/.acl and /usr/local/web/.acl
    para las directivas, salvo que estén deshabilitadas with
    

    
    
      <Directory />
    
      
        AllowOverride None

    Directiva AddDefaultCharset
    

    

    Descripción:Default charset parameter to be added when a response
content-type is text/plain or text/html
    

    Sintaxis:AddDefaultCharset On|Off|charset
    

    Valor por defecto:AddDefaultCharset Off
    

    Contexto:server config, virtual host, directory, .htaccess
    

    Anula:FileInfo
    

    Estado:Core
    

    Módulo:core
    

    
    
    This directive specifies a default value for the media type
    charset parameter (the name of a character encoding) to be added
    to a response if and only if the response's content-type is either
    text/plain or text/html.  This should override
    any charset specified in the body of the response via a META
    element, though the exact behavior is often dependent on the user's client
    configuration. A setting of AddDefaultCharset Off
    disables this functionality. AddDefaultCharset On enables
    a default charset of iso-8859-1. Any other value is assumed
    to be the charset to be used, which should be one of the
    IANA registered
    charset values for use in Internet media types (MIME types).
    For example:
    

    
    
      AddDefaultCharset utf-8
    
    

    
    AddDefaultCharset should only be used when all
    of the text resources to which it applies are known to be in that
    character encoding and it is too inconvenient to label their charset
    individually. One such example is to add the charset parameter
    to resources containing generated content, such as legacy CGI
    scripts, that might be vulnerable to cross-site scripting attacks
    due to user-provided data being included in the output.  Note, however,
    that a better solution is to just fix (or delete) those scripts, since
    setting a default charset does not protect users that have enabled
    the "auto-detect character encoding" feature on their browser.

    Directiva AllowEncodedSlashes
    

    

    Descripción:Determines whether encoded path separators in URLs are allowed to
be passed through
    

    Sintaxis:AllowEncodedSlashes On|Off
    

    Valor por defecto:AllowEncodedSlashes Off
    

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    Compatibilidad:Available in Apache httpd 2.0.46 and later
    

    
    
    The AllowEncodedSlashes directive allows URLs
    which contain encoded path separators (%2F for /
    and additionally %5C for \ on according systems)
    to be used. Normally such URLs are refused with a 404 (Not found) error.
    

    
    Turning AllowEncodedSlashes On is
    mostly useful when used in conjunction with PATH_INFO.
    

    
    Note
    
      
    Allowing encoded slashes does not imply decoding.
      Occurrences of %2F or %5C (only on
      according systems) will be left as such in the otherwise decoded URL
      string.

    Directiva AllowOverride
    

    

    Descripción:Types of directives that are allowed in
.htaccess files
    

    Sintaxis:AllowOverride All|None|directive-type
[directive-type] ...
    

    Valor por defecto:AllowOverride None (2.3.9 and later), AllowOverride All (2.3.8 and earlier)
    

    Contexto:directory
    

    Estado:Core
    

    Módulo:core
    

    
    
    When the server finds an .htaccess file (as
    specified by AccessFileName)
    it needs to know which directives declared in that file can override
    earlier configuration directives.
    

    
    Only available in <Directory> sections
    
    AllowOverride is valid only in
    <Directory>
    sections specified without regular expressions, not in <Location>, <DirectoryMatch> or
    <Files> sections.
    
    

    
    When this directive is set to None, then
    .htaccess files are completely ignored.
    In this case, the server will not even attempt to read
    .htaccess files in the filesystem.
    

    
    When this directive is set to All, then any
    directive which has the .htaccess Context is allowed in
    .htaccess files.
    

    
    The directive-type can be one of the following
    groupings of directives.
    

    
    
      
    AuthConfig
    

      
    

      Allow use of the authorization directives (AuthDBMGroupFile,
      AuthDBMUserFile,
      AuthGroupFile,
      AuthName,
      AuthType, AuthUserFile, Require, etc.).

     (ErrorDocument,
      ForceType,
      LanguagePriority,
      SetHandler,
      SetInputFilter,

      mod_mime Add* and Remove* directives),
      document meta data (Header, RequestHeader, SetEnvIf, SetEnvIfNoCase, BrowserMatch, CookieExpires, CookieDomain, CookieStyle, CookieTracking, CookieName),
      mod_rewrite directives RewriteEngine, RewriteOptions, RewriteBase, RewriteCond, RewriteRule) and
      Action from
      mod_actions.

      Allow use of the directives controlling specific directory
      features (Options and
      XBitHack).
      An equal sign may be given followed by a comma (but no spaces)
      separated lists of options that may be set using the Options command.
    
    
    

    
    Example:
    

    
    
      AllowOverride AuthConfig Indexes
    
    

    
    In the example above all directives that are neither in the group
    AuthConfig nor Indexes cause an internal
    server error.
    

    
    For security and performance reasons, do not set
    AllowOverride to anything other than None 
    in your <Directory /> block. Instead, find (or
    create) the <Directory> block that refers to the
    directory where you're actually planning to place a
    .htaccess file.

    This directive enables the generation of
    Content-MD5 headers as defined in RFC1864
    respectively RFC2616.
    

    
    MD5 is an algorithm for computing a "message digest"
    (sometimes called "fingerprint") of arbitrary-length data, with
    a high degree of confidence that any alterations in the data
    will be reflected in alterations in the message digest.
    

    
    The Content-MD5 header provides an end-to-end
    message integrity check (MIC) of the entity-body. A proxy or
    client may check this header for detecting accidental
    modification of the entity-body in transit. Example header:
    

    
    
      Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
    
    

    
    Note that this can cause performance problems on your server
    since the message digest is computed on every request (the
    values are not cached).
    

    
    Content-MD5 is only sent for documents served
    by the core, and not by any module. For example,
    SSI documents, output from CGI scripts, and byte range responses
    do not have this header.

    Directiva <Directory>
    

    

    Descripción:Enclose a group of directives that apply only to the
named file-system directory, sub-directories, and their contents.
    

    Sintaxis:<Directory directory-path>
... </Directory>
    

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    
    
    <Directory> and
    </Directory> are used to enclose a group of
    directives that will apply only to the named directory,
    sub-directories of that directory, and the files within the respective 
    directories.  Any directive that is allowed
    in a directory context may be used. Directory-path is
    either the full path to a directory, or a wild-card string using
    Unix shell-style matching. In a wild-card string, ? matches
    any single character, and * matches any sequences of
    characters. You may also use [] character ranges. None
    of the wildcards match a `/' character, so <Directory
    /*/public_html> will not match
    /home/user/public_html, but <Directory
    /home/*/public_html> will match. Example:
    

    
    
      <Directory /usr/local/httpd/htdocs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
    

    
    
      
    Be careful with the directory-path arguments:
      They have to literally match the filesystem path which Apache httpd uses
      to access the files. Directives applied to a particular
      <Directory> will not apply to files accessed from
      that same directory via a different path, such as via different symbolic
      links.
    
    
    

    
    Regular
    expressions can also be used, with the addition of the
    ~ character. For example:
    

    
    
      <Directory ~ "^/www/.*/[0-9]{3}">
    
    

    
    would match directories in /www/ that consisted of
    three numbers.
    

    
    If multiple (non-regular expression) <Directory> sections
    match the directory (or one of its parents) containing a document,
    then the directives are applied in the order of shortest match
    first, interspersed with the directives from the .htaccess files. For example,
    with
    

    
    
      <Directory />
    
      
        AllowOverride None
    
          
      </Directory>
    
      
    
      <Directory /home/>
    
      
        AllowOverride FileInfo
    
          
      </Directory>
    
    

    
    for access to the document /home/web/dir/doc.html
    the steps are:
    

    
      
      
    • Apply directive AllowOverride None
      (disabling .htaccess files).
      • 

      
    • Apply directive AllowOverride FileInfo (for
      directory /home).
      • 

      
    • Apply any FileInfo directives in
      /home/.htaccess, /home/web/.htaccess and
      /home/web/dir/.htaccess in that order.
      • 
    
    

    
    Regular expressions are not considered until after all of the
    normal sections have been applied. Then all of the regular
    expressions are tested in the order they appeared in the
    configuration file. For example, with
    

    
    
      <Directory ~ abc$>
    
      
        # ... directives here ...
    
          
      </Directory>
    
    

    
    the regular expression section won't be considered until after
    all normal <Directory>s and
    .htaccess files have been applied. Then the regular
    expression will match on /home/abc/public_html/abc and
    the corresponding <Directory> will
    be applied.
    

   
    Note that the default access for
    <Directory /> is Allow from All.
    This means that Apache httpd will serve any file mapped from an URL. It is
    recommended that you change this with a block such
    as
    

    
    
      <Directory />
    
      
        Order Deny,Allow
    
        Deny from All
    
          
      </Directory>
    
    

    
    and then override this for directories you
    want accessible. See the Security Tips page for more
    details.
    

    
    The directory sections occur in the httpd.conf file.
    <Directory> directives
    cannot nest, and cannot appear in a <Limit> or <LimitExcept> section.

    However, it takes as an argument a

      <DirectoryMatch "^/www/(.+/)?[0-9]{3}">
    
    

    
    would match directories in /www/ that consisted of three

    Compatability
    
      Prior to 2.3.9, this directive implicitly applied to sub-directories

      only directories that match the expression are affected by the enclosed
      directives.
    
    

    
    Trailing Slash
    
      This directive applies to requests for directories that may or may 
      not end in a trailing slash, so expressions that are anchored to the 
      end of line ($) must be written with care.

    This directive sets the directory from which httpd
    will serve files. Unless matched by a directive like Alias, the server appends the
    path from the requested URL to the document root to make the
    path to the document. Example:
    

    
    
      DocumentRoot /usr/web
    
    

    
    then an access to
    http://www.my.host.com/index.html refers to
    /usr/web/index.html. If the directory-path is 
    not absolute then it is assumed to be relative to the ServerRoot.
    

    
    The DocumentRoot should be specified without
    a trailing slash.

    Módulo:core
    

    
    
    This directive controls whether the httpd may use
    memory-mapping if it needs to read the contents of a file during
    delivery.  By default, when the handling of a request requires
    access to the data within a file -- for example, when delivering a
    server-parsed file using mod_include -- Apache httpd
    memory-maps the file if the OS supports it.
    

    
    This memory-mapping sometimes yields a performance improvement.
    But in some environments, it is better to disable the memory-mapping
    to prevent operational problems:
    

    
      
    
    • On some multiprocessor systems, memory-mapping can reduce the
    performance of the httpd.
      • 
    
    • Deleting or truncating a file while httpd
      has it memory-mapped can cause httpd to
      crash with a segmentation fault.
    
      • 
    
    

    
    For server configurations that are vulnerable to these problems,
    you should disable memory-mapping of delivered files by specifying:
    

    
    
      EnableMMAP Off
    
    

    
    For NFS mounted files, this feature may be disabled explicitly for
    the offending files by specifying:
    

    
    
      <Directory "/path-to-nfs-files">
      
        EnableMMAP Off

    Compatibilidad:Available in version 2.0.44 and later. Default changed to Off in
version 2.3.9.
    

    
    
    This directive controls whether httpd may use the
    sendfile support from the kernel to transmit file contents to the client.
    By default, when the handling of a request requires no access
    to the data within a file -- for example, when delivering a
    static file -- Apache httpd uses sendfile to deliver the file contents
    without ever reading the file if the OS supports it.
    

    
    This sendfile mechanism avoids separate read and send operations,
    and buffer allocations. But on some platforms or within some
    filesystems, it is better to disable this feature to avoid
    operational problems:
    

    
      
    
    • Some platforms may have broken sendfile support that the build
    system did not detect, especially if the binaries were built on
    another box and moved to such a machine with broken sendfile
    support.
      • 
    
    • On Linux the use of sendfile triggers TCP-checksum
    offloading bugs on certain networking cards when using IPv6.
      • 
    
    • On Linux on Itanium, sendfile may be unable to handle files
    over 2GB in size.
      • 
    
    • With a network-mounted DocumentRoot (e.g., NFS, SMB, CIFS, FUSE),
    the kernel may be unable to serve the network file through
    its own cache.
      • 
    
    

    
    For server configurations that are not vulnerable to these problems,
    you may enable this feature by specifying:
    

    
    
      EnableSendfile On
    
    

    
    For network mounted files, this feature may be disabled explicitly
    for the offending files by specifying:
    

    
    
      <Directory "/path-to-nfs-files">
      
        EnableSendfile Off
      
      </Directory>
    
    
    
    Please note that the per-directory and .htaccess configuration
       of EnableSendfile is not supported by
       mod_cache_disk.
       Only global definition of EnableSendfile
       is taken into account by the module.

    In the event of a problem or error, Apache httpd can be configured
    to do one of four things,
    

    
      
      
    1. output a simple hardcoded error message
      2. 

      
    2. output a customized message
      3. 

      
    3. redirect to a local URL-path to handle the
      problem/error
      4. 

      
    4. redirect to an external URL to handle the
      problem/error
      5. 
    
    

    
    The first option is the default, while options 2-4 are
    configured using the ErrorDocument
    directive, which is followed by the HTTP response code and a URL
    or a message. Apache httpd will sometimes offer additional information
    regarding the problem/error.
    

    
    URLs can begin with a slash (/) for local web-paths (relative
    to the DocumentRoot), or be a
    full URL which the client can resolve. Alternatively, a message
    can be provided to be displayed by the browser. Examples:
    

    
    
      ErrorDocument 500 http://foo.example.com/cgi-bin/tester
    
      ErrorDocument 404 /cgi-bin/bad_urls.pl
    
      ErrorDocument 401 /subscription_info.html
    
      ErrorDocument 403 "Sorry can't allow you access today"
    
    

    
    Additionally, the special value default can be used
    to specify Apache httpd's simple hardcoded message.  While not required
    under normal circumstances, default will restore
    Apache httpd's simple hardcoded message for configurations that would
    otherwise inherit an existing ErrorDocument.
    

    
    
      ErrorDocument 404 /cgi-bin/bad_urls.pl

    
      <Directory /web/docs>
    
      
        ErrorDocument 404 default
    
          
      </Directory>
    
    

    
    Note that when you specify an ErrorDocument
    that points to a remote URL (ie. anything with a method such as
    http in front of it), Apache HTTP Server will send a redirect to the
    client to tell it where to find the document, even if the
    document ends up being on the same server. This has several
    implications, the most important being that the client will not
    receive the original error status code, but instead will
    receive a redirect status code. This in turn can confuse web
    robots and other clients which try to determine if a URL is
    valid using the status code. In addition, if you use a remote
    URL in an ErrorDocument 401, the client will not
    know to prompt the user for a password since it will not
    receive the 401 status code. Therefore, if you use an
    ErrorDocument 401 directive then it must refer to a local
    document.
    

    
    Microsoft Internet Explorer (MSIE) will by default ignore
    server-generated error messages when they are "too small" and substitute
    its own "friendly" error messages. The size threshold varies depending on
    the type of error, but in general, if you make your error document
    greater than 512 bytes, then MSIE will show the server-generated
    error rather than masking it.  More information is available in
    Microsoft Knowledge Base article Q294807.
    

    
    Although most error messages can be overriden, there are certain
    circumstances where the internal messages are used regardless of the
    setting of ErrorDocument.  In
    particular, if a malformed request is detected, normal request processing
    will be immediately halted and the internal error message returned.
    This is necessary to guard against security problems caused by
    bad requests.
    
   
    
    If you are using mod_proxy, you may wish to enable
    ProxyErrorOverride so that you can provide
    custom error messages on behalf of your Origin servers. If you don't enable ProxyErrorOverride,
    Apache httpd will not generate custom error documents for proxied content.

    Directiva ErrorLog
    

    

    Descripción:Location where the server will log errors
    

    Sintaxis: ErrorLog file-path|syslog[:facility]
    

    Valor por defecto:ErrorLog logs/error_log (Unix) ErrorLog logs/error.log (Windows and OS/2)
    

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    
    
    The ErrorLog directive sets the name of
    the file to which the server will log any errors it encounters. If
    the file-path is not absolute then it is assumed to be 
    relative to the ServerRoot.
    

    
    Example
    
    ErrorLog /var/log/httpd/error_log
    
    

    
    If the file-path
    begins with a pipe character "|" then it is assumed to be a
    command to spawn to handle the error log.
    

    
    Example
    
    ErrorLog "|/usr/local/bin/httpd_errors"
    
    

    
    See the notes on piped logs for
    more information.
    

    
    Using syslog instead of a filename enables logging
    via syslogd(8) if the system supports it. The default is to use
    syslog facility local7, but you can override this by
    using the syslog:facility syntax where
    facility can be one of the names usually documented in
    syslog(1).  The facility is effectively global, and if it is changed
    in individual virtual hosts, the final facility specified affects the
    entire server.
    

    
    Example
    
    ErrorLog syslog:user
    
    

    
    SECURITY: See the security tips
    document for details on why your security could be compromised
    if the directory where log files are stored is writable by
    anyone other than the user that starts the server.
    
    
    Note
    
      
    When entering a file path on non-Unix platforms, care should be taken
      to make sure that only forward slashed are used even though the platform
      may allow the use of back slashes. In general it is a good idea to always 
      use forward slashes throughout the configuration files.

    Directiva ErrorLogFormat
    

    

    Descripción:Format specification for error log entries
    

    Sintaxis: ErrorLog [connection|request] format
    

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    Compatibilidad:Available in Apache httpd 2.3.9 and later
    

    
    
    ErrorLogFormat allows to specify what
    supplementary information is logged in the error log in addition to the
    actual log message.
    

    
    Simple example
    
        ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M"
    
    

    
    Specifying connection or request as first
    paramter allows to specify additional formats, causing additional
    information to be logged when the first message is logged for a specific
    connection or request, respectivly. This additional information is only
    logged once per connection/request. If a connection or request is processed
    without causing any log message, the additional information is not logged
    either.
    

    
    It can happen that some format string items do not produce output.  For
    example, the Referer header is only present if the log message is
    associated to a request and the log message happens at a time when the
    Referer header has already been read from the client.  If no output is
    produced, the default behaviour is to delete everything from the preceeding
    space character to the next space character.  This means the log line is
    implicitly divided into fields on non-whitespace to whitespace transitions.
    If a format string item does not produce output, the whole field is
    ommitted.  For example, if the remote address %a in the log
    format [%t] [%l] [%a] %M  is not available, the surrounding
    brackets are not logged either.  Space characters can be escaped with a
    backslash to prevent them from delimiting a field.  The combination '% '
    (percent space) is a zero-witdh field delimiter that does not produce any
    output.
    

    
    The above behaviour can be changed by adding modifiers to the format
    string item. A - (minus) modifier causes a minus to be logged if the
    respective item does not produce any output. In once-per-connection/request
    formats, it is also possible to use the + (plus) modifier. If an
    item with the plus modifier does not produce any output, the whole line is
    ommitted.
    

    
    A number as modifier can be used to assign a log severity level to a
    format item. The item will only be logged if the severity of the log
    message is not higher than the specified log severity level. The number can
    range from 1 (alert) over 4 (warn) and 7 (debug) to 15 (trace8).
    

    
    Some format string items accept additional parameters in braces.
    

    
    Format String Description
    

    %%
        The percent sign
    

    %...a

        APR/OS error status code and string
    

    %...F
        Source file name and line number of the log call

        Thread ID of current thread
    

    %...t
        The current time
    

    %...{u}t
        The current time including micro-seconds

            micro-seconds
    

    %...v

            of the current server.
    

    %...V
        The server name of the server serving the request according to the
            UseCanonicalName

        Non-field delimiting space
    

    %  (percent space)
        Field delimiter (no output)
    

    

    
    The log ID format %L produces a unique id for a connection
    or request. This can be used to correlate which log lines belong to the
    same connection or request, which request happens on which connection.
    A %L format string is also available in
    mod_log_config, to allow to correlate access log entries
    with error log lines. If mod_unique_id is loaded, its
    unique id will be used as log ID for requests.
    

    
    Example (somewhat similar to default format)
    
        ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P] %7F: %E: [client\ %a]
        %M% ,\ referer\ %{Referer}i"
    
    

    
    Example (similar to the 2.2.x format)
    
        ErrorLogFormat "[%t] [%l] %7F: %E: [client\ %a]
        %M% ,\ referer\ %{Referer}i"
    
    

    
    Advanced example with request/connection log IDs
    
        ErrorLogFormat "[%{uc}t] [%-m:%-l] [R:%L] [C:%{C}L] %7F: %E: %M"
    
        ErrorLogFormat request "[%{uc}t] [R:%L] Request %k on C:%{c}L pid:%P tid:%T"
    
        ErrorLogFormat request "[%{uc}t] [R:%L] UA:'%+{User-Agent}i'"
    
        ErrorLogFormat request "[%{uc}t] [R:%L] Referer:'%+{Referer}i'"
    
        ErrorLogFormat connection "[%{uc}t] [C:%{c}L] local\ %a remote\ %A"

    This option tracks additional data per worker about the

    can see these variables during runtime by configuring 
    mod_status.  Note that other modules may
    rely on this scoreboard.
    

    
    This setting applies to the entire server, and cannot be
    enabled or disabled on a virtualhost-by-virtualhost basis.
    The collection of extended status information can slow down
    the server.  Also note that this setting cannot be changed
    during a graceful restart.
    

    
    
    
    Note that loading mod_status will change 
    the default behavior to ExtendedStatus On, while other
    third party modules may do the same.  Such modules rely on
    collecting detailed information about the state of all workers.
    The default is changed by mod_status beginning
    with version 2.3.6; the previous default was always Off.

    The FileETag directive configures the file
    attributes that are used to create the ETag (entity
    tag) response header field when the document is based on a static file.
    (The ETag value is used in cache management to save
    network bandwidth.) The
    FileETag directive allows you to choose
    which of these -- if any -- should be used. The recognized keywords are:
    
    

    
    
     
    INode
    
     
    The file's i-node number will be included in the calculation
    
     
    MTime
    
     
    The date and time the file was last modified will be included
    
     
    Size
    
     
    The number of bytes in the file will be included
    
     
    All
    
     
    All available fields will be used. This is equivalent to:
         
    FileETag INode MTime Size
    
     
    None
    
     
    If a document is file-based, no ETag field will be
       included in the response
    
    
    

    
    The INode, MTime, and Size
    keywords may be prefixed with either + or -,
    which allow changes to be made to the default setting inherited
    from a broader scope. Any keyword appearing without such a prefix
    immediately and completely cancels the inherited setting.
    

    
    If a directory's configuration includes
    FileETag INode MTime Size, and a
    subdirectory's includes FileETag -INode,
    the setting for that subdirectory (which will be inherited by
    any sub-subdirectories that don't override it) will be equivalent to
    FileETag MTime Size.
    
    
    Warning
    
    Do not change the default for directories or locations that have WebDAV
    enabled and use mod_dav_fs as a storage provider.
    mod_dav_fs uses INode MTime Size
    as a fixed format for ETag comparisons on conditional requests.
    These conditional requests will break if the ETag format is
    changed via FileETag.
    
    
    
    Server Side Includes
    
    An ETag is not generated for responses parsed by mod_include, 
    since the response entity can change without a change of the INode, MTime, or Size 
    of the static file with embedded SSI directives.

    The <Files> directive
    limits the scope of the enclosed directives by filename. It is comparable
    to the <Directory>
    and <Location>
    directives. It should be matched with a </Files>
    directive. The directives given within this section will be applied to
    any object with a basename (last component of filename) matching the
    specified filename. <Files>
    sections are processed in the order they appear in the
    configuration file, after the <Directory> sections and
    .htaccess files are read, but before <Location> sections. Note
    that <Files> can be nested
    inside <Directory> sections to restrict the
    portion of the filesystem they apply to.
    

    
    The filename argument should include a filename, or
    a wild-card string, where ? matches any single character,
    and * matches any sequences of characters.
    Regular expressions 
    can also be used, with the addition of the
    ~ character. For example:
    

    
    
      <Files ~ "\.(gif|jpe?g|png)$">
    
    

    
    would match most common Internet graphics formats. <FilesMatch> is preferred,
    however.
    

    
    Note that unlike <Directory> and <Location> sections, <Files> sections can be used inside
    .htaccess files. This allows users to control access to
    their own files, at a file-by-file level.

    When placed into an .htaccess file or a
    <Directory>, or
    <Location> or
    <Files>
    section, this directive forces all matching files to be served
    with the content type identification given by
    media-type. For example, if you had a directory full of
    GIF files, but did not want to label them all with .gif,
    you might want to use:
    

    
    
      ForceType image/gif
    
    

    
    Note that this directive overrides other indirect media type
    associations defined in mime.types or via the
    AddType.
    

    
    You can also override more general
    ForceType settings
    by using the value of None:
    

    
    
      # force all files to be image/gif:
    
      <Location /images>
    
        
          ForceType image/gif
    
            
      </Location>
    
      
    
      # but normal mime-type associations here:
    
      <Location /images/mixed>
    
      
        ForceType None
    
          
      </Location>
    
    

    
    This directive primarily overrides the content types generated for
    static files served out of the filesystem.  For resources other than 
    static files, where the generator of the response typically specifies 
    a Content-Type, this directive has no effect.

    Directiva HostnameLookups

    This directive enables DNS lookups so that host names can be
    logged (and passed to CGIs/SSIs in REMOTE_HOST).
    The value Double refers to doing double-reverse
    DNS lookup. That is, after a reverse lookup is performed, a forward
    lookup is then performed on that result. At least one of the IP
    addresses in the forward lookup must match the original
    address. (In "tcpwrappers" terminology this is called
    PARANOID.)
    

    
    Regardless of the setting, when mod_authz_host is
    used for controlling access by hostname, a double reverse lookup
    will be performed.  This is necessary for security. Note that the
    result of this double-reverse isn't generally available unless you
    set HostnameLookups Double. For example, if only
    HostnameLookups On and a request is made to an object
    that is protected by hostname restrictions, regardless of whether
    the double-reverse fails or not, CGIs will still be passed the
    single-reverse result in REMOTE_HOST.
    

    
    The default is Off in order to save the network
    traffic for those sites that don't truly need the reverse
    lookups done. It is also better for the end users because they
    don't have to suffer the extra latency that a lookup entails.
    Heavily loaded sites should leave this directive
    Off, since DNS lookups can take considerable
    amounts of time. The utility logresolve, compiled by
    default to the bin subdirectory of your installation
    directory, can be used to look up host names from logged IP addresses
    offline.

    would match HTTP/1.0 requests without a Host: header.
    

    
    You may compare the value of any variable in the request headers
    ($req), response headers ($resp) or environment ($env) in your

    The <IfDefine test>...</IfDefine>
     section is used to mark directives that are conditional. The
    directives within an <IfDefine>
    section are only processed if the test is true. If 
    test is false, everything between the start and end markers is
    ignored.
    

    
    The test in the <IfDefine> section directive can be one of two forms:
    

    
      
      
    • parameter-name
      • 

      
    • !parameter-name
      • 
    
    

    
    In the former case, the directives between the start and end
    markers are only processed if the parameter named
    parameter-name is defined. The second format reverses
    the test, and only processes the directives if
    parameter-name is not defined.
    

    
    The parameter-name argument is a define as given on the
    httpd command line via -Dparameter
     at the time the server was started or by the Define directive.
    

    
    <IfDefine> sections are
    nest-able, which can be used to implement simple
    multiple-parameter tests. Example:
    

    
    
      httpd -DReverseProxy -DUseCache -DMemCache ...
    
      
    
      # httpd.conf

            LoadModule cache_disk_module   modules/mod_cache_disk.so

    The <IfModule test>...</IfModule>
    section is used to mark directives that are conditional on the presence of
    a specific module. The directives within an <IfModule> section are only processed if the test
    is true. If test is false, everything between the start and
    end markers is ignored.
    

    
    The test in the <IfModule> section directive can be one of two forms:
    

    
      
      
    • module
      • 

      
    • !module
      • 
    
    

    
    In the former case, the directives between the start and end
    markers are only processed if the module named module
    is included in Apache httpd -- either compiled in or
    dynamically loaded using LoadModule. The second format reverses the test,
    and only processes the directives if module is
    not included.
    

    
    The module argument can be either the module identifier or
    the file name of the module, at the time it was compiled.  For example,
    rewrite_module is the identifier and
    mod_rewrite.c is the file name. If a module consists of
    several source files, use the name of the file containing the string
    STANDARD20_MODULE_STUFF.
    

    
    <IfModule> sections are
    nest-able, which can be used to implement simple multiple-module
    tests.
    

    
    This section should only be used if you need to have one
    configuration file that works whether or not a specific module
    is available. In normal operation, directives need not be
    placed in <IfModule>
    sections.

    Compatibilidad:Wildcard matching available in 2.0.41 and later, directory
wildcard matching available in 2.3.6 and later
    

    
    
    This directive allows inclusion of other configuration files
    from within the server configuration files.
    

    
    Shell-style (fnmatch()) wildcard characters can be used
    in the filename or directory parts of the path to include several files
    at once, in alphabetical order. In addition, if
    Include points to a directory, rather than a file,
    Apache httpd will read all files in that directory and any subdirectory.
    However, including entire directories is not recommended, because it is
    easy to accidentally leave temporary files in a directory that can cause
    httpd to fail. Instead, we encourage you to use the
    wildcard syntax shown below, to include files that match a particular
    pattern, such as *.conf, for example.
    

    
    When a wildcard is specified for a file component of
    the path, and no file matches the wildcard, the
    Include
    directive will be silently ignored. When a wildcard is
    specified for a directory component of the path, and
    no directory matches the wildcard, the
    Include directive will
    fail with an error saying the directory cannot be found.
    
    

    
    For further control over the behaviour of the server when no files or
    directories match, prefix the path with the modifiers optional
    or strict. If optional is specified, any wildcard
    file or directory that does not match will be silently ignored. If
    strict is specified, any wildcard file or directory that does
    not match at least one file will cause server startup to fail.
    

    
    When a directory or file component of the path is
    specified exactly, and that directory or file does not exist,
    Include directive will fail with an
    error saying the file or directory cannot be found.
    

    
    The file path specified may be an absolute path, or may be relative 
    to the ServerRoot directory.
    

    
    Examples:
    

    
    
      Include /usr/local/apache2/conf/ssl.conf
    
      Include /usr/local/apache2/conf/vhosts/*.conf
    
    

    
    Or, providing paths relative to your ServerRoot directory:
    

    
    
      Include conf/ssl.conf
    
      Include conf/vhosts/*.conf
    
    

    
    Wildcards may be included in the directory or file portion of the
    path. In the following example, the server will fail to load if no
    directories match conf/vhosts/*, but will load successfully if no
    files match *.conf.
    
  
    
    
      Include conf/vhosts/*/vhost.conf
    
      Include conf/vhosts/*/*.conf
    
    

    
    In this example, the server will fail to load if either
    conf/vhosts/* matches no directories, or if *.conf matches no files:
    

    
    
      Include strict conf/vhosts/*/*.conf
    
    
  
    
    In this example, the server load successfully if either conf/vhosts/*
    matches no directories, or if *.conf matches no files:
    

    
    
      Include optional conf/vhosts/*/*.conf

    Módulo:core
    

    
    
    The Keep-Alive extension to HTTP/1.0 and the persistent
    connection feature of HTTP/1.1 provide long-lived HTTP sessions
    which allow multiple requests to be sent over the same TCP
    connection. In some cases this has been shown to result in an
    almost 50% speedup in latency times for HTML documents with
    many images. To enable Keep-Alive connections, set
    KeepAlive On.
    

    
    For HTTP/1.0 clients, Keep-Alive connections will only be
    used if they are specifically requested by a client. In
    addition, a Keep-Alive connection with an HTTP/1.0 client can
    only be used when the length of the content is known in
    advance. This implies that dynamic content such as CGI output,
    SSI pages, and server-generated directory listings will
    generally not use Keep-Alive connections to HTTP/1.0 clients.
    For HTTP/1.1 clients, persistent connections are the default
    unless otherwise specified. If the client requests it, chunked
    encoding will be used in order to send content of unknown
    length over persistent connections.
    

    
    When a client uses a Keep-Alive connection it will be counted
    as a single "request" for the MaxConnectionsPerChild directive, regardless
    of how many requests are sent using the connection.

    timeout can be also set in milliseconds. Once a request has been
    received, the timeout value specified by the
    Timeout directive applies.
    

    
    Setting KeepAliveTimeout to a high value
    may cause performance problems in heavily loaded servers. The
    higher the timeout, the more server processes will be kept
    occupied waiting on connections with idle clients.
    
    
    
    In a name-based virtual host context, the value of the first
    defined virtual host (the default host) in a set of NameVirtualHost will be used.

    Módulo:core
    

    
    
    Access controls are normally effective for
    all access methods, and this is the usual
    desired behavior. In the general case, access control
    directives should not be placed within a
    <Limit> section.
    

    
    The purpose of the <Limit>
    directive is to restrict the effect of the access controls to the
    nominated HTTP methods. For all other methods, the access
    restrictions that are enclosed in the <Limit> bracket will have no
    effect. The following example applies the access control
    only to the methods POST, PUT, and
    DELETE, leaving all other methods unprotected:
    

    
    
      <Limit POST PUT DELETE>
    
      
        Require valid-user
    
          
      </Limit>
    
    

    
    The method names listed can be one or more of: GET,
    POST, PUT, DELETE,
    CONNECT, OPTIONS,
    PATCH, PROPFIND, PROPPATCH,
    MKCOL, COPY, MOVE,
    LOCK, and UNLOCK. The method name is
    case-sensitive. If GET is used it will also
    restrict HEAD requests. The TRACE method
    cannot be limited (see TraceEnable).
    

    
    A <LimitExcept> section should always be
    used in preference to a <Limit>
    section when restricting access, since a <LimitExcept> section provides protection
    against arbitrary methods.
    

    
    The <Limit> and
    <LimitExcept>
    directives may be nested.  In this case, each successive level of
    <Limit> or <LimitExcept> directives must
    further restrict the set of methods to which access controls apply.
    

    
    When using
    <Limit> or
    <LimitExcept> directives with
    the Require directive,
    note that the first Require
    to succeed authorizes the request, regardless of the presence of other
    Require directives.
    

    
    For example, given the following configuration, all users will
    be authorized for POST requests, and the
    Require group editors directive will be ignored
    in all cases:
    

    
    
      <LimitExcept GET>
      
        Require valid-user
       
      </LimitExcept>
    
      <Limit POST>
      
        Require group editors
       
      </Limit>

    <LimitExcept> and

    i.e., it is the opposite of a <Limit> section and can be used to control
    both standard and nonstandard/unrecognized methods. See the
    documentation for <Limit> for more details.
    

    
    For example:

    Compatibilidad:Available in Apache httpd 2.0.47 and later
    

    
    
    An internal redirect happens, for example, when using the Action directive, which internally
    redirects the original request to a CGI script. A subrequest is Apache httpd's
    mechanism to find out what would happen for some URI if it were requested.
    For example, mod_dir uses subrequests to look for the
    files listed in the DirectoryIndex
    directive.
    

    
    LimitInternalRecursion prevents the server
    from crashing when entering an infinite loop of internal redirects or
    subrequests. Such loops are usually caused by misconfigurations.
    

    
    The directive stores two different limits, which are evaluated on
    per-request basis. The first number is the maximum number of
    internal redirects, that may follow each other. The second number
    determines, how deep subrequests may be nested. If you specify only one
    number, it will be assigned to both limits.

    This directive specifies the number of bytes from 0
    (meaning unlimited) to 2147483647 (2GB) that are allowed in a
    request body. See the note below for the limited applicability
    to proxy requests.
    

    
    The LimitRequestBody directive allows
    the user to set a limit on the allowed size of an HTTP request
    message body within the context in which the directive is given
    (server, per-directory, per-file or per-location). If the client
    request exceeds that limit, the server will return an error
    response instead of servicing the request. The size of a normal
    request message body will vary greatly depending on the nature of
    the resource and the methods allowed on that resource. CGI scripts
    typically use the message body for retrieving form information.
    Implementations of the PUT method will require
    a value at least as large as any representation that the server
    wishes to accept for that resource.
    

    
    This directive gives the server administrator greater
    control over abnormal client request behavior, which may be
    useful for avoiding some forms of denial-of-service
    attacks.
    

    
    If, for example, you are permitting file upload to a particular
    location, and wish to limit the size of the uploaded file to 100K,
    you might use the following directive:
    

    
    
      LimitRequestBody 102400
    
    
    
    
    For a full description of how this directive is interpreted by 
    proxy requests, see the mod_proxy documentation.

    Number is an integer from 0 (meaning unlimited) to
    32767. The default value is defined by the compile-time
    constant DEFAULT_LIMIT_REQUEST_FIELDS (100 as
    distributed).
    

    
    The LimitRequestFields directive allows
    the server administrator to modify the limit on the number of
    request header fields allowed in an HTTP request. A server needs
    this value to be larger than the number of fields that a normal
    client request might include. The number of request header fields
    used by a client rarely exceeds 20, but this may vary among
    different client implementations, often depending upon the extent
    to which a user has configured their browser to support detailed
    content negotiation. Optional HTTP extensions are often expressed
    using request header fields.
    

    
    This directive gives the server administrator greater
    control over abnormal client request behavior, which may be
    useful for avoiding some forms of denial-of-service attacks.
    The value should be increased if normal clients see an error
    response from the server that indicates too many fields were
    sent in the request.
    

    
    For example:
    

    
    
      LimitRequestFields 50

    This directive specifies the number of bytes
    that will be allowed in an HTTP request header.
    

    
    The LimitRequestFieldSize directive
    allows the server administrator to reduce or increase the limit 
    on the allowed size of an HTTP request header field. A server
    needs this value to be large enough to hold any one header field 
    from a normal client request. The size of a normal request header 
    field will vary greatly among different client implementations, 
    often depending upon the extent to which a user has configured
    their browser to support detailed content negotiation. SPNEGO
    authentication headers can be up to 12392 bytes.

    This directive sets the number of bytes that will be 
    allowed on the HTTP request-line.
    

    
    The LimitRequestLine directive allows
    the server administrator to reduce or increase the limit on the allowed size
    of a client's HTTP request-line. Since the request-line consists of the
    HTTP method, URI, and protocol version, the
    LimitRequestLine directive places a
    restriction on the length of a request-URI allowed for a request
    on the server. A server needs this value to be large enough to
    hold any of its resource names, including any information that
    might be passed in the query part of a GET request.

    Directiva <Location>
    

    

    Descripción:Applies the enclosed directives only to matching
URLs
    

    Sintaxis:<Location
    URL-path|URL> ... </Location>
    

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    
    
    The <Location> directive
    limits the scope of the enclosed directives by URL. It is similar to the
    <Directory>
    directive, and starts a subsection which is terminated with a
    </Location> directive. <Location> sections are processed in the
    order they appear in the configuration file, after the <Directory> sections and
    .htaccess files are read, and after the <Files> sections.
    

    
    <Location> sections operate
    completely outside the filesystem.  This has several consequences.
    Most importantly, <Location>
    directives should not be used to control access to filesystem
    locations.  Since several different URLs may map to the same
    filesystem location, such access controls may by circumvented.
    

    
    The enclosed directives will be applied to the request if the path component
    of the URL meets any of the following criteria:
    
    
    
      
      
    • The specified location matches exactly the path component of the URL.
      
      • 
      
    • The specified location, which ends in a forward slash, is a prefix 
      of the path component of the URL (treated as a context root).
      
      • 
      
    • The specified location, with the addition of a trailing slash, is a 
      prefix of the path component of the URL (also treated as a context root).
      
      • 
    
    
    
    
    In the example below, where no trailing slash is used, requests to 
    /private1, /private1/ and /private1/file.txt will have the enclosed
    directives applied, but /private1other would not. 
    
    
    
    
      <Location /private1>
          ...
    
    
    
    
    In the example below, where a trailing slash is used, requests to 
    /private2/ and /private2/file.txt will have the enclosed
    directives applied, but /private2 and /private2other would not. 
    
    
    
    
      <Location /private2/>
          ...
    
    

    
    When to use <Location>
    

    
    Use <Location> to apply
    directives to content that lives outside the filesystem.  For
    content that lives in the filesystem, use <Directory> and <Files>.  An exception is
    <Location />, which is an easy way to 
    apply a configuration to the entire server.
    
    
    

    
    For all origin (non-proxy) requests, the URL to be matched is a
    URL-path of the form /path/.  No scheme, hostname,
    port, or query string may be included.  For proxy requests, the
    URL to be matched is of the form
    scheme://servername/path, and you must include the
    prefix.
    

    
    The URL may use wildcards. In a wild-card string, ? matches
    any single character, and * matches any sequences of
    characters. Neither wildcard character matches a / in the URL-path.
    

    
    Regular expressions
    can also be used, with the addition of the ~ 
    character. For example:
    

    
    
      <Location ~ "/(extra|special)/data">
    
    

    
    would match URLs that contained the substring /extra/data
    or /special/data. The directive <LocationMatch> behaves
    identical to the regex version of <Location>, and is preferred, for the
    simple reason that ~ is hard to distinguish from
    - in many fonts.
    

    
    The <Location>
    functionality is especially useful when combined with the
    SetHandler
    directive. For example, to enable status requests, but allow them
    only from browsers at example.com, you might use:
    

    
    
      <Location /status>
    
      
        SetHandler server-status
    
        Require host example.com
    
          
      </Location>
    
    

    
    Note about / (slash)
    
      
    The slash character has special meaning depending on where in a
      URL it appears. People may be used to its behavior in the filesystem
      where multiple adjacent slashes are frequently collapsed to a single
      slash (i.e., /home///foo is the same as
      /home/foo). In URL-space this is not necessarily true.
      The <LocationMatch>
      directive and the regex version of <Location> require you to explicitly specify multiple
      slashes if that is your intention.
    

      
    For example, <LocationMatch ^/abc> would match
      the request URL /abc but not the request URL 
      //abc. The (non-regex) <Location> directive behaves similarly when used for
      proxy requests. But when (non-regex) <Location> is used for non-proxy requests it will
      implicitly match multiple slashes with a single slash. For example,
      if you specify <Location /abc/def> and the
      request is to /abc//def then it will match.

    When a particular level is specified, messages from all
    other levels of higher significance will be reported as well.
    E.g., when LogLevel info is specified,
    then messages with log levels of notice and
    warn will also be posted.
    

    
    Using a level of at least crit is
    recommended.
    

    
    For example:
    

    
    
      LogLevel notice
    
    

    
    Note
    
      
    When logging to a regular file messages of the level
      notice cannot be suppressed and thus are always
      logged. However, this doesn't apply when logging is done
      using syslog.
    
    
    

    
    Specifying a level without a module name will reset the level
    for all modules to that level.  Specifying a level with a module
    name will set the level for that module only. It is possible to
    use the module source file name, the module identifier, or the
    module identifier with the trailing _module omitted
    as module specification. This means the following three specifications
    are equivalent:
    

    
    
      LogLevel info ssl:warn
    
      LogLevel info mod_ssl.c:warn
    
      LogLevel info ssl_module:warn
    
    
    

    
    It is also possible to change the level per directory:
    

    
    
        LogLevel info
    
        <Directory /usr/local/apache/htdocs/app>
    
          LogLevel debug
    
        </Files>
    
    

    
    
        Per directory loglevel configuration only affects messages that are
	logged after the request has been parsed and that are associated with
	the request. Log messages which are associated with the connection or
	the server are not affected.

    The Mutex directive sets the mechanism,
    and optionally the lock file location, that httpd and modules use
    to serialize access to resources.  Specify default as
    the first argument to change the settings for all mutexes; specify
    a mutex name (see table below) as the first argument to override
    defaults only for that mutex.
    

    
    The Mutex directive is typically used in
    the following exceptional situations:
    

    
      
        
    • change the mutex mechanism when the default mechanism selected
        by APR has a functional or performance
        problem
      • 

        
    • change the directory used by file-based mutexes when the
        default directory does not support locking
      • 
    
    

    
    Supported modules
    
    
    This directive only configures mutexes which have been registered
    with the core server using the ap_mutex_register() API.
    All modules bundled with httpd support the Mutex
    directive, but third-party modules may not.  Consult the documentation
    of the third-party module, which must indicate the mutex name(s) which
    can be configured if this directive is supported.
    
    
    

    
    The following mutex mechanisms are available:
    
    
      
        
    • default | yes
        
      This selects the default locking implementation, as determined by
        APR.  The default locking implementation can
        be displayed by running httpd with the 
        -V option.
      • 

        
    • none | no
        
      This effectively disables the mutex, and is only allowed for a
        mutex if the module indicates that it is a valid choice.  Consult the
        module documentation for more information.
      • 

        
    • posixsem
        
      This is a mutex variant based on a Posix semaphore.
      

        
      Warning
      
        
      The semaphore ownership is not recovered if a thread in the process
        holding the mutex segfaults, resulting in a hang of the web server.
      
        
      
        
      • 

        
    • sysvsem
        
      This is a mutex variant based on a SystemV IPC semaphore.
      

        
      Warning
      
        
      It is possible to "leak" SysV semaphores if processes crash 
        before the semaphore is removed.
      
	
      

        
      Security
      
        
      The semaphore API allows for a denial of service attack by any
        CGIs running under the same uid as the webserver (i.e.,
        all CGIs, unless you use something like suexec
        or cgiwrapper).
      
	
      
        
      • 

        
    • sem
        
      This selects the "best" available semaphore implementation, choosing
        between Posix and SystemV IPC semaphores, in that order.
      • 

        
    • pthread
        
      This is a mutex variant based on cross-process Posix thread
        mutexes.
      

        
      Warning
      
        
      On most systems, if a child process terminates abnormally while
        holding a mutex that uses this implementation, the server will deadlock
        and stop responding to requests.  When this occurs, the server will
        require a manual restart to recover.
      
        
      Solaris is a notable exception as it provides a mechanism which
        usually allows the mutex to be recovered after a child process
        terminates abnormally while holding a mutex.
      
        
      If your system implements the
        pthread_mutexattr_setrobust_np() function, you may be able
        to use the pthread option safely.
      
        
      
        
      • 

        
    • fcntl:/path/to/mutex
        
      This is a mutex variant where a physical (lock-)file and the 
        fcntl() function are used as the mutex.
      

        
      Warning
      
        
      When multiple mutexes based on this mechanism are used within
        multi-threaded, multi-process environments, deadlock errors (EDEADLK)
        can be reported for valid mutex operations if fcntl()
        is not thread-aware, such as on Solaris.
      
	
      
        
      • 

        
    • flock:/path/to/mutex
        
      This is similar to the fcntl:/path/to/mutex method
        with the exception that the flock() function is used to
        provide file locking.
      • 

        
    • file:/path/to/mutex
        
      This selects the "best" available file locking implementation,
        choosing between fcntl and flock, in that
        order.
      • 
    
    

    
    Most mechanisms are only available on selected platforms, where the 
    underlying platform and APR support it.  Mechanisms
    which aren't available on all platforms are posixsem,
    sysvsem, sem, pthread, fcntl, 
    flock, and file.
    

    
    With the file-based mechanisms fcntl and flock,
    the path, if provided, is a directory where the lock file will be created.
    The default directory is httpd's run-time file directory relative to
    ServerRoot.  Always use a local disk
    filesystem for /path/to/mutex and never a directory residing
    on a NFS- or AFS-filesystem.  The basename of the file will be the mutex
    type, an optional instance string provided by the module, and unless the
    OmitPID keyword is specified, the process id of the httpd 
    parent process will be appended to to make the file name unique, avoiding
    conflicts when multiple httpd instances share a lock file directory.  For
    example, if the mutex name is mpm-accept and the lock file
    directory is /var/httpd/locks, the lock file name for the
    httpd instance with parent process id 12345 would be 
    /var/httpd/locks/mpm-accept.12345.
    

    
    Security
    
    
    It is best to avoid putting mutex files in a world-writable
    directory such as /var/tmp because someone could create
    a denial of service attack and prevent the server from starting by
    creating a lockfile with the same name as the one the server will try
    to create.
    
    
    

    
    The following table documents the names of mutexes used by httpd
    and bundled modules.
    

    
    
            Mutex name
            Module(s)
            Protected resource
	
    

    
            mpm-accept
            prefork and worker MPMs
            incoming connections, to avoid the thundering herd problem;
            for more information, refer to the
            performance tuning
            documentation
	
    

    
            authdigest-client
            mod_auth_digest
            client list in shared memory
	
    

    
            authdigest-opaque
            mod_auth_digest
            counter in shared memory
	
    

    
            ldap-cache
            mod_ldap
            LDAP result cache
	
    

    
            rewrite-map
            mod_rewrite
            communication with external mapping programs, to avoid
            intermixed I/O from multiple requests
	
    

    
            ssl-cache
            mod_ssl
            SSL session cache
	
    

    
            ssl-stapling
            mod_ssl
            OCSP stapling response cache
	
    

    
            watchdog-callback
            mod_watchdog
            callback function of a particular client module
	
    

    

    
    The OmitPID keyword suppresses the addition of the httpd
    parent process id from the lock file name.
    

    
    In the following example, the mutex mechanism for the MPM accept
    mutex will be changed from the compiled-in default to fcntl,
    with the associated lock file created in directory
    /var/httpd/locks.  The mutex mechanism for all other mutexes
    will be changed from the compiled-in default to sysvsem.
    

    
    
    Mutex default sysvsem
    
    Mutex mpm-accept fcntl:/var/httpd/locks

    Directiva NameVirtualHost
    

    

    Descripción:Designates an IP address for name-virtual
hosting
    

    Sintaxis:NameVirtualHost addr[:port]
    

    Contexto:server config
    

    Estado:Core
    

    Módulo:core
    

    


    A single NameVirtualHost directive 
identifies a set of identical virtual hosts on which the server will  
further select from on the basis of the hostname 
requested by the client.  The NameVirtualHost
directive is a required directive if you want to configure 
name-based virtual hosts.
    


    This directive, and the corresponding VirtualHost,
must be qualified with a port number if the server supports both HTTP 
and HTTPS connections.
    


    Although addr can be a hostname, it is recommended
that you always use an IP address or a wildcard.  A wildcard
NameVirtualHost matches only virtualhosts that also have a literal wildcard
as their argument.
    


    In cases where a firewall or other proxy receives the requests and 
forwards them on a different IP address to the server, you must specify the
IP address of the physical interface on the machine which will be
servicing the requests. 
    


     In the example below, requests received on interface 192.0.2.1 and port 80 
will only select among the first two virtual hosts. Requests received on
port 80 on any other interface will only select among the third and fourth
virtual hosts. In the common case where the interface isn't important 
to the mapping, only the "*:80" NameVirtualHost and VirtualHost directives 
are necessary.
    

   
    
      NameVirtualHost 192.0.2.1:80
    
      NameVirtualHost *:80

    

      <VirtualHost 192.0.2.1:80>
    
        ServerName namebased-a.example.com
    
      </VirtualHost>
    
      
    
      <VirtualHost 192.0.2.1:80>
    
        Servername namebased-b.example.com
    
      </VirtualHost>
    
      
    
      <VirtualHost *:80>
    
        ServerName namebased-c.example.com 
    
      </VirtualHost>
    
      
    
      <VirtualHost *:80>
    
        ServerName namebased-d.example.com 
    
      </VirtualHost>
    
      
    

    
    

    
    If no matching virtual host is found, then the first listed
    virtual host that matches the IP address and port will be used.
    


    
    IPv6 addresses must be enclosed in square brackets, as shown
    in the following example:
    

    
    
      NameVirtualHost [2001:db8::a00:20ff:fea7:ccea]:8080
    
    

    
    Argument to <VirtualHost>
      directive
    
      
    Note that the argument to the <VirtualHost> directive must
      exactly match the argument to the NameVirtualHost directive.
    

      
    
        NameVirtualHost 192.0.2.2:80
    
        <VirtualHost 192.0.2.2:80>
    
        # ...
    
        </VirtualHost>

    Estado:Core
    

    Módulo:core
    

    
    
    The Options directive controls which
    server features are available in a particular directory.
    

    
    option can be set to None, in which
    case none of the extra features are enabled, or one or more of
    the following:
    

    
    
      
    All
    

      
    All options except for MultiViews. This is the default
      setting.
    

      
    ExecCGI
    

      
    
      Execution of CGI scripts using mod_cgi
      is permitted.
    

      
    FollowSymLinks
    

      
    

      The server will follow symbolic links in this directory.
      
    
      
    Even though the server follows the symlink it does not
      change the pathname used to match against <Directory> sections.
    
      
    Note also, that this option gets ignored if set
      inside a <Location>
      section.
    
      
    Omitting this option should not be considered a security restriction,
      since symlink testing is subject to race conditions that make it
      circumventable.
    
      
    

      
    Includes
    

      
    
      Server-side includes provided by mod_include
      are permitted.
    

      
    IncludesNOEXEC
    

      
    

      Server-side includes are permitted, but the #exec
      cmd and #exec cgi are disabled. It is still
      possible to #include virtual CGI scripts from
      ScriptAliased
      directories.
    

      
    Indexes
    

      
    
      If a URL which maps to a directory is requested, and there
      is no DirectoryIndex
      (e.g., index.html) in that directory, then
      mod_autoindex will return a formatted listing
      of the directory.
    

      
    MultiViews
    

      
    
      Content negotiated
      "MultiViews" are allowed using
      mod_negotiation.
      
    Note
     
    This option gets ignored if set
      anywhere other than <Directory>, as mod_negotiation
      needs real resources to compare against and evaluate from.
    
      
    

      
    SymLinksIfOwnerMatch
    

      
    The server will only follow symbolic links for which the
      target file or directory is owned by the same user id as the
      link.

      
    Note
     
    This option gets ignored if
      set inside a <Location> section.
    
      
    This option should not be considered a security restriction,
      since symlink testing is subject to race conditions that make it
      circumventable.
    
      
    
    
    

    
    Normally, if multiple Options could
    apply to a directory, then the most specific one is used and
    others are ignored; the options are not merged. (See how sections are merged.)
    However if all the options on the
    Options directive are preceded by a
    + or - symbol, the options are
    merged. Any options preceded by a + are added to the
    options currently in force, and any options preceded by a
    - are removed from the options currently in
    force. 
    

    
    Warning
    
    
    Mixing Options with a + or
    - with those without is not valid syntax, and is likely
    to cause unexpected results.
    
    
    

    
    For example, without any + and - symbols:
    

    
    
      <Directory /web/docs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
      
    
      <Directory /web/docs/spec>
    
      
        Options Includes
    
          
      </Directory>
    
    

    
    then only Includes will be set for the
    /web/docs/spec directory. However if the second
    Options directive uses the + and
    - symbols:
    

    
    
      <Directory /web/docs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
      
    
      <Directory /web/docs/spec>
    
      
        Options +Includes -Indexes
    
          
      </Directory>
    
    

    
    then the options FollowSymLinks and
    Includes are set for the /web/docs/spec
    directory.
    

    
    Note
    
      
    Using -IncludesNOEXEC or
      -Includes disables server-side includes completely
      regardless of the previous setting.
    
    
    

    
    The default in the absence of any other settings is
    All.

    This directive specifies the protocol used for a specific listening socket.
       The protocol is used to determine which module should handle a request, and
       to apply protocol specific optimizations with the AcceptFilter
       directive.
    

    
    You only need to set the protocol if you are running on non-standard ports, otherwise http is assumed for port 80 and https for port 443.
    

    
    For example, if you are running https on a non-standard port, specify the protocol explicitly:
    

    
    
      Protocol https
    
    

    
    You can also specify the protocol using the Listen directive.

    Módulo:core
    

    Compatibilidad:Win32 only;
option Registry-Strict is available in Apache HTTP Server 2.0 and
later
    

    
    
    This directive is used to control how Apache httpd finds the
    interpreter used to run CGI scripts. The default setting is
    Script. This causes Apache httpd to use the interpreter pointed to
    by the shebang line (first line, starting with #!) in the
    script. On Win32 systems this line usually looks like:
    

    
    
      #!C:/Perl/bin/perl.exe
    
    

    
    or, if perl is in the PATH, simply:
    

    
    
      #!perl
    
    

    
    Setting ScriptInterpreterSource Registry will
    cause the Windows Registry tree HKEY_CLASSES_ROOT to be
    searched using the script file extension (e.g., .pl) as a
    search key. The command defined by the registry subkey
    Shell\ExecCGI\Command or, if it does not exist, by the subkey
    Shell\Open\Command is used to open the script file. If the
    registry keys cannot be found, Apache httpd falls back to the behavior of the
    Script option.
    

    
    Security
    
    
    Be careful when using ScriptInterpreterSource
    Registry with ScriptAlias'ed directories, because
    Apache httpd will try to execute every file within this
    directory. The Registry setting may cause undesired
    program calls on files which are typically not executed. For
    example, the default open command on .htm files on
    most Windows systems will execute Microsoft Internet Explorer, so
    any HTTP request for an .htm file existing within the
    script directory would start the browser in the background on the
    server. This is a good way to crash your system within a minute or
    so.
    
    
    

    
    The option Registry-Strict which is new in Apache HTTP Server
    2.0 does the same thing as Registry but uses only the
    subkey Shell\ExecCGI\Command. The
    ExecCGI key is not a common one. It must be
    configured manually in the windows registry and hence prevents
    accidental program calls on your system.

    The ServerAdmin sets the contact address
    that the server includes in any error messages it returns to the
    client. If the httpd doesn't recognize the supplied argument
    as an URL, it
    assumes, that it's an email-address and prepends it with
    mailto: in hyperlink targets. However, it's recommended to
    actually use an email address, since there are a lot of CGI scripts that
    make that assumption. If you want to use an URL, it should point to another
    server under your control. Otherwise users may not be able to contact you in
    case of errors.
    

    
    It may be worth setting up a dedicated address for this, e.g.
    

    
    
      ServerAdmin www-admin@foo.example.com

    Contexto:server config, virtual host
    

    Estado:Core
    

    Módulo:core
    

    
    
    The ServerName directive sets the
    request scheme, hostname and
    port that the server uses to identify itself.  This is used when
    creating redirection URLs.
    

    
    Additionally, ServerName is used (possibly
    in conjunction with ServerAlias) to uniquely
    identify a virtual host, when using name-based virtual hosts.
    
    
    
    For example, if the name of the
    machine hosting the web server is simple.example.com,
    but the machine also has the DNS alias www.example.com
    and you wish the web server to be so identified, the following
    directive should be used:
    

    
    
      ServerName www.example.com:80
    
    

    
    The ServerName directive
    may appear anywhere within the definition of a server. However,
    each appearance overrides the previous appearance (within that
    server).
    

    
    If no ServerName is specified, then the
    server attempts to deduce the hostname by performing a reverse
    lookup on the IP address. If no port is specified in the
    ServerName, then the server will use the
    port from the incoming request. For optimal reliability and
    predictability, you should specify an explicit hostname and port
    using the ServerName directive.
    

    
    If you are using name-based virtual hosts,
    the ServerName inside a
    <VirtualHost>
    section specifies what hostname must appear in the request's
    Host: header to match this virtual host.
    

    
    Sometimes, the server runs behind a device that processes SSL,
    such as a reverse proxy, load balancer or SSL offload
    appliance. When this is the case, specify the
    https:// scheme and the port number to which the
    clients connect in the ServerName directive
    to make sure that the server generates the correct
    self-referential URLs. 
    
    

    
    See the description of the
    UseCanonicalName and
    UseCanonicalPhysicalPort directives for
    settings which determine whether self-referential URLs (e.g., by the
    mod_dir module) will refer to the
    specified port, or to the port number given in the client's request.
    
    

    
    
    
    Failure to set ServerName to a name that
    your server can resolve to an IP address will result in a startup
    warning. httpd will then use whatever hostname it can
    determine, using the system's hostname command. This
    will almost never be the hostname you actually want.

    The ServerSignature directive allows the
    configuration of a trailing footer line under server-generated
    documents (error messages, mod_proxy ftp directory
    listings, mod_info output, ...). The reason why you
    would want to enable such a footer line is that in a chain of proxies,
    the user often has no possibility to tell which of the chained servers
    actually produced a returned error message.
    

    
    The Off
    setting, which is the default, suppresses the footer line (and is
    therefore compatible with the behavior of Apache-1.2 and
    below). The On setting simply adds a line with the
    server version number and ServerName of the serving virtual host,
    and the EMail setting additionally creates a
    "mailto:" reference to the ServerAdmin of the referenced
    document.
    

    
    After version 2.0.44, the details of the server version number
    presented are controlled by the ServerTokens directive.

    After version 2.0.44, this directive also controls the
    information presented by the ServerSignature directive.
    
    
    
    Setting ServerTokens to less than
    minimal is not recommended because it makes it more
    difficult to debug interoperational problems. Also note that
    disabling the Server: header does nothing at all to make your
    server more secure; the idea of "security through obscurity"
    is a myth and leads to a false sense of safety.

    When placed into an .htaccess file or a

    section, this directive forces all matching files to be parsed
    through the handler given by
    handler-name. For example, if you had a directory you
    wanted to be parsed entirely as imagemap rule files, regardless
    of extension, you might put the following into an
    .htaccess file in that directory:
    

    
    
      SetHandler imap-file
    
    

    
    Another example: if you wanted to have the server display a
    status report whenever a URL of
    http://servername/status was called, you might put
    the following into httpd.conf:
    

    
    
      <Location /status>
    
      
        SetHandler server-status

    You can override an earlier defined SetHandler

    in the /www/data/ directory for server-side
    includes.
    

    
    
      <Directory /www/data/>
    
      
        SetOutputFilter INCLUDES

    If more than one filter is specified, they must be separated
    by semicolons in the order in which they should process the
    content.

    1. When reading data from the client, the length of time to
      wait for a TCP packet to arrive if the read buffer is
      empty.
      2. 

      
    2. When writing data to the client, the length of time to wait
      for an acknowledgement of a packet if the send buffer is
      full.
      3. 

      
    3. In mod_cgi, the length of time to wait for
      output from a CGI script.
      4. 

      
    4. In mod_ext_filter, the length of time to
      wait for output from a filtering process.
      5. 

      
    5. In mod_proxy, the default timeout value if
      ProxyTimeout is not
      configured.
      6.

    Compatibilidad:Available in Apache HTTP Server 1.3.34, 2.0.55 and later
    

    
    
    This directive overrides the behavior of TRACE for both
    the core server and mod_proxy.  The default
    TraceEnable on permits TRACE requests per
    RFC 2616, which disallows any request body to accompany the request.
    TraceEnable off causes the core server and
    mod_proxy to return a 405 (Method not
    allowed) error to the client.
    

    
    Finally, for testing and diagnostic purposes only, request
    bodies may be allowed using the non-compliant TraceEnable 
    extended directive.  The core (as an origin server) will
    restrict the request body to 64k (plus 8k for chunk headers if
    Transfer-Encoding: chunked is used).  The core will
    reflect the full headers and all chunk headers with the response
    body.  As a proxy server, the request body is not restricted to 64k.

    Contexto:server config, virtual host, directory
    

    Estado:Core
    

    Módulo:core
    

    
    
    In many situations Apache httpd must construct a self-referential
    URL -- that is, a URL that refers back to the same server. With
    UseCanonicalName On Apache httpd will use the hostname and port
    specified in the ServerName
    directive to construct the canonical name for the server. This name
    is used in all self-referential URLs, and for the values of
    SERVER_NAME and SERVER_PORT in CGIs.
    

    
    With UseCanonicalName Off Apache httpd will form
    self-referential URLs using the hostname and port supplied by
    the client if any are supplied (otherwise it will use the
    canonical name, as defined above). These values are the same
    that are used to implement name-based virtual hosts,
    and are available with the same clients. The CGI variables
    SERVER_NAME and SERVER_PORT will be
    constructed from the client supplied values as well.
    

    
    An example where this may be useful is on an intranet server
    where you have users connecting to the machine using short
    names such as www. You'll notice that if the users
    type a shortname, and a URL which is a directory, such as
    http://www/splat, without the trailing
    slash then Apache httpd will redirect them to
    http://www.domain.com/splat/. If you have
    authentication enabled, this will cause the user to have to
    authenticate twice (once for www and once again
    for www.domain.com -- see the
    FAQ on this subject for more information). But if
    UseCanonicalName is set Off, then
    Apache httpd will redirect to http://www/splat/.
    

    
    There is a third option, UseCanonicalName DNS,
    which is intended for use with mass IP-based virtual hosting to
    support ancient clients that do not provide a
    Host: header. With this option Apache httpd does a
    reverse DNS lookup on the server IP address that the client
    connected to in order to work out self-referential URLs.
    

    
    Warning
    
    
    If CGIs make assumptions about the values of SERVER_NAME
    they may be broken by this option. The client is essentially free
    to give whatever value they want as a hostname. But if the CGI is
    only using SERVER_NAME to construct self-referential URLs
    then it should be just fine.

    In many situations Apache httpd must construct a self-referential
    URL -- that is, a URL that refers back to the same server. With
    UseCanonicalPhysicalPort On Apache httpd will, when
    constructing the canonical port for the server to honor
    the UseCanonicalName directive,
    provide the actual physical port number being used by this request
    as a potential port. With UseCanonicalPhysicalPort Off
    Apache httpd will not ever use the actual physical port number, instead
    relying on all configured information to construct a valid port number.
    

    
    Note
    
    
    The ordering of when the physical port is used is as follows:

    
     UseCanonicalName On
    
     
      
      
    • Port provided in Servername
      •

    • Default port
      • 
     
    
    
    
    With UseCanonicalPhysicalPort Off, the
    physical ports are removed from the ordering.

    Directiva <VirtualHost>
    

    

    Descripción:Contains directives that apply only to a specific

    Estado:Core
    

    Módulo:core
    

    
    
    <VirtualHost> and
    </VirtualHost> are used to enclose a group of
    directives that will apply only to a particular virtual host. Any
    directive that is allowed in a virtual host context may be
    used. When the server receives a request for a document on a
    particular virtual host, it uses the configuration directives
    enclosed in the <VirtualHost>
    section. Addr can be:
    

    
      
      
    • The IP address of the virtual host;
      • 

      
    • A fully qualified domain name for the IP address of the
      virtual host (not recommended);
      • 

      
    • The character *, which is used only in combination with
      NameVirtualHost * to match all IP addresses; or
      • 

      
    • The string _default_, which is used only
      with IP virtual hosting to catch unmatched IP addresses.
      • 
    
    

    
    Example
    
      <VirtualHost 10.1.2.3>
    
      
        ServerAdmin webmaster@host.example.com
    
        DocumentRoot /www/docs/host.example.com
    
        ServerName host.example.com
    
        ErrorLog logs/host.example.com-error_log
    
        TransferLog logs/host.example.com-access_log
    
          
      </VirtualHost>
    
    


    
    IPv6 addresses must be specified in square brackets because
    the optional port number could not be determined otherwise.  An
    IPv6 example is shown below:
    

    
    
      <VirtualHost [2001:db8::a00:20ff:fea7:ccea]>
    
      
        ServerAdmin webmaster@host.example.com
    
        DocumentRoot /www/docs/host.example.com
    
        ServerName host.example.com
    
        ErrorLog logs/host.example.com-error_log
    
        TransferLog logs/host.example.com-access_log
    
          
      </VirtualHost>
    
    

    
    Each Virtual Host must correspond to a different IP address,
    different port number or a different host name for the server,
    in the former case the server machine must be configured to
    accept IP packets for multiple addresses. (If the machine does
    not have multiple network interfaces, then this can be
    accomplished with the ifconfig alias command -- if
    your OS supports it).
    

    
    Note
    
    
    The use of <VirtualHost> does
    not affect what addresses Apache httpd listens on. You
    may need to ensure that Apache httpd is listening on the correct addresses
    using Listen.
    
    
    

    
    When using IP-based virtual hosting, the special name
    _default_ can be specified in
    which case this virtual host will match any IP address that is
    not explicitly listed in another virtual host. In the absence
    of any _default_ virtual host the "main" server config,
    consisting of all those definitions outside any VirtualHost
    section, is used when no IP-match occurs.
    

    
    You can specify a :port to change the port that is
    matched. If unspecified then it defaults to the same port as the
    most recent Listen
    statement of the main server. You may also specify :*
    to match all ports on that address. (This is recommended when used
    with _default_.)
    

    
    A ServerName should be
    specified inside each <VirtualHost> block. If it is absent, the
    ServerName from the "main"
    server configuration will be inherited.
    

    
    If no matching virtual host is found, then the first listed
    virtual host that matches the IP address will be used.  As a
    consequence, the first listed virtual host is the default virtual
    host.
    

    
    Security
    
    
    See the security tips
    document for details on why your security could be compromised if the
    directory where log files are stored is writable by anyone other
    than the user that starts the server.

    Sommaire
    

    
    Ce module multi-processus (MPM) implémente un serveur web basé
    exclusivement sur les threads et optimisé pour Novell NetWare.
    

    
    Le thread maître est chargé du lancement de threads esclaves qui
    attendent les connexions et les traitent au fur et à mesure de leur
    arrivée. Le serveur HTTP Apache essaie toujours de maintenir
    plusieurs threads
    esclaves en spare (en réserve) ou inactifs. De cette
    façon, les clients n'ont pas besoin d'attendre le lancement d'un
    nouveau thread enfant pour que leurs requêtes soient traitées.
    

    
    Les directives StartThreads, MinSpareThreads, MaxSpareThreads, et MaxThreads contrôlent
    la manière dont le thread maître crée les threads esclaves afin de
    traiter les requêtes. En général, Apache httpd s'auto-régule correctement,
    et la plupart des sites ne nécessitent aucune modification des
    valeurs par défaut de ces directives. Pour les sites dont le serveur
    est limité en mémoire, il peut s'avérer nécessaire de diminuer la
    valeur de la directive MaxThreads afin d'éviter une
    hyper-activité du serveur (arrêts de threads inactifs et lancement incessant
    de nouveau threads). Vous trouverez plus d'informations à
    propos du contrôle de la création de processus dans le document conseils en matière de
    performances.
    

    
    La directive MaxRequestsPerChild
    contrôle la fréquence à laquelle le serveur recycle ses processus
    en arrêtant les anciens et en en lançant de nouveaux. Sous le
    système d'exploitation NetWare, il est vivement recommandé de
    laisser cette directive à 0, ce qui permet aux threads esclaves de
    continuer à traiter les requêtes indéfiniment.

    le nombre maximum de threads esclaves que l'on désire autoriser. La
    valeur par défaut correspondant à la valeur codée en dur à la

    diminuée, comme dans l'exemple suivant :

    Summary
    

    
    Warning
    
      
    The session modules make use of HTTP cookies, and as such can fall
      victim to Cross Site Scripting attacks, or expose potentially private
      information to clients. Please ensure that the relevant risks have
      been taken into account before enabling the session functionality on
      your server.
    
    
    

    
    This submodule of mod_session provides support for the
    storage of user sessions within a SQL database using the
    mod_dbd module.
    

    
    Sessions can either be anonymous, where the session is
    keyed by a unique UUID string stored on the browser in a cookie, or
    per user, where the session is keyed against the userid of
    the logged in user.
    

    
    SQL based sessions are hidden from the browser, and so offer a measure of
    privacy without the need for encryption.
    

    
    Different webservers within a server farm may choose to share a database,
    and so share sessions with one another.
    

    
    For more details on the session interface, see the documentation for
    the mod_session module.

    DBD Configuration
    

      
    Before the mod_session_dbd module can be configured to maintain a
      session, the mod_dbd module must be configured to make the various database queries
      available to the server.
    

      
    There are four queries required to keep a session maintained, to select an existing session,
      to update an existing session, to insert a new session, and to delete an expired or empty
      session. These queries are configured as per the example below.
    

      
    Sample DBD configuration
    DBDriver pgsql
DBDParams "dbname=apachesession user=apache password=xxxxx host=localhost"
DBDPrepareSQL "delete from session where key = %s" deletesession
DBDPrepareSQL "update session set value = %s, expiry = %lld, key = %s where key = %s" updatesession
DBDPrepareSQL "insert into session (value, expiry, key) values (%s, %lld, %s)" insertsession
DBDPrepareSQL "select value from session where key = %s and (expiry = 0 or expiry > %lld)" selectsession
DBDPrepareSQL "delete from session where expiry != 0 and expiry < %lld" cleansession
    

    

    
    top
    

    

    Anonymous Sessions
    

      
    Anonymous sessions are keyed against a unique UUID, and stored on the
      browser within an HTTP cookie. This method is similar to that used by most
      application servers to store session information.
    

      
    To create a simple anonymous session and store it in a postgres database
      table called apachesession, and save the session ID in a cookie
      called session, configure the session as follows:
    

      
    SQL based anonymous session
    Session On
SessionDBDCookieName session path=/
    

    

      
    For more examples on how the session can be configured to be read
      from and written to by a CGI application, see the
      mod_session examples section.
    

      
    For documentation on how the session can be used to store username
      and password details, see the mod_auth_form module.
    

    
    top
    

    

    Per User Sessions
    

      
    Per user sessions are keyed against the username of a successfully
      authenticated user. It offers the most privacy, as no external handle
      to the session exists outside of the authenticated realm.
    

      
    Per user sessions work within a correctly configured authenticated
      environment, be that using basic authentication, digest authentication
      or SSL client certificates. Due to the limitations of who came first,
      the chicken or the egg, per user sessions cannot be used to store
      authentication credentials from a module like
      mod_auth_form.
    

      
    To create a simple per user session and store it in a postgres database
      table called apachesession, and with the session keyed to the
      userid, configure the session as follows:
    

      
    SQL based per user session
    Session On
SessionDBDPerUser On
    

    

    
    top
    

    

    Database Housekeeping
    
      
    Over the course of time, the database can be expected to start accumulating
      expired sessions. At this point, the mod_session_dbd module
      is not yet able to handle session expiry automatically.
    

      
    Warning
    
      
    The administrator will need to set up an external process via cron to clean
      out expired sessions.

    An optional list of cookie attributes can be specified, as per the example below.
    These attributes are inserted into the cookie as is, and are not interpreted by
    Apache. Ensure that your attributes are defined correctly as per the cookie specification.

    Module:mod_session_dbd
    

    
    
    The SessionDBDCookieRemove flag controls whether the cookies
    containing the session ID will be removed from the headers during request processing.
    

    
    In a reverse proxy situation where the Apache server acts as a server frontend for
    a backend origin server, revealing the contents of the session ID cookie to the backend
    could be a potential privacy violation. When set to on, the session ID cookie will be
    removed from the incoming HTTP headers.

    If an attempt to update the session affects no rows, the insert query will be
    called to insert the session into the database. If the database supports InsertOrUpdate,
    override this query to perform the update in one query instead of two.

    概要
    


    このモジュールは、
http://example.com/~user/
構文を使ってユーザ専用ディレクトリにアクセスできるようにします。

    UserDir ディレクティブは、
    ユーザのドキュメントへのリクエストを受けた時に使う
    ユーザのホームディレクトリ中の、実際のディレクトリを
    設定します。
    directory-filename には次のどれかを指定します:
    

    
      
      
    • ディレクトリ名か下に示すようなパターン。
      • 

      
    • disabled キーワード。
      enabled キーワード (下記参照) で明示的に
      指定されたユーザ以外の
      全てのユーザ名-ディレクトリ変換を
      しないようにします。
      • 

      
    • disabled キーワードと、スペース区切りのユーザ名リスト。
      このリスト中に含まれるユーザ名に対しては、たとえ
      enabled 節にあったとしても、
      決してディレクトリ変換は行われません。
      • 

      
    • enabled キーワードとスペース区切りのユーザ名リスト。
      全体では変換が無効になっていたとしても、
      これらのユーザ名にはディレクトリ変換が行われます。
      ただし、disabled 節にもあれば変換はされません。
      
      • 
    
    

    
    もし enabled も disabled
    キーワードも UserDir に現われていなければ、
    引数はファイル名パターンとして扱われ、
    名前からディレクトリへの変換の指定を行なう時に使われます。
    http://www.example.com/~bob/one/two.html
    へのリクエストは次のように変換されます:
    


    

    UserDir ディレクティブ
変換後のパス
    

    UserDir public_html~bob/public_html/one/two.html
    

    UserDir /usr/web/usr/web/bob/one/two.html
    

    UserDir /home/*/www/home/bob/www/one/two.html
    

    

    
    次のディレクティブはクライアントに対してリダイレクトを
    送信します:
    


    

    UserDir ディレクティブ
変換後のパス
    

    UserDir http://www.example.com/usershttp://www.example.com/users/bob/one/two.html
    

    UserDir
http://www.example.com/*/usrhttp://www.example.com/bob/usr/one/two.html
    

    UserDir
http://www.example.com/~*/http://www.example.com/~bob/one/two.html
    

     


    
      このディレクティブを使うときは注意してください;
      "UserDir ./" は
      "/~root" から "/" へマップしますが、
      これは望ましい動作ではないでしょう。
      "UserDir disabled root" 宣言を
      設定の中に含めておくことを強くお薦めします。
      追加情報に Directory
      ディレクティブや
      セキュリティ
      Tips のページもご覧下さい。

    


    追加の例:
    


    少数のユーザのみが UserDir
ディレクトリを利用し、それ以外には利用させたくない場合は
次を使いましょう:
    


    
UserDir disabled
    
UserDir enabled user1 user2 user3

    


    大部分のユーザは UserDir ディレクトリを利用するけれど、
少数の人は不許可にしたい場合は、次を使いましょう:
    


    
UserDir enabled
    
UserDir disabled user4 user5 user6

    


    他のユーザディレクトリを指定することもできます。
次のようなコマンドを使うと:
    


    
Userdir public_html /usr/web http://www.example.com/

    


    http://www.example.com/~bob/one/two.html へのリクエストはまず
~bob/public_html/one/two.html のページを調べ、その次に
/usr/web/bob/one/two.html を調べ、最後に http://www.example.com/bob/one/two.html
へのリダイレクトを送ります。
    


    リダイレクトを加える場合は、リストの最後の選択肢でなければなりません。
Apache はリダイレクトが成功するかどうかを決めることはできませんので、
リストの前の方にリダイレクトを書くと、それが必ず使用される選択肢に
なってしまいます。
    


    2.1.4 以降では、ユーザディレクトリ置換機能はデフォルトでは起動しません。
それ以前のバージョンでは、UserDir
ディレクティブが存在しなければ、UserDir public_html 
であると仮定されていました。

    Description:Personnalisation des en-têtes de requêtes et de réponses
HTTP
    

    Statut:Extension
    

    Identificateur de Module:headers_module
    

    Fichier Source:mod_headers.c
    

    Sommaire
    

    
    Ce module fournit des directives permettant de contrôler et
    modifier les en-têtes de requêtes et de réponses HTTP. Les en-têtes
    peuvent être fusionnés, remplacés ou supprimés.
    

    


    top
    

    

    Chronologie du traitement
    

    
    Les directives fournies par mod_headers peuvent
    s'insérer presque partout dans la configuration du serveur, et on
    peut limiter leur portée en les plaçant dans des sections de configuration.
    

    
    La chronologie du traitement est importante et est affectée par
    l'ordre d'apparition des directives dans le fichier de configuration
    et par leur placement dans les sections de configuration. Ainsi,
    ces deux directives ont un effet différent si leur ordre est inversé
    :
    

    
    RequestHeader append MirrorID "mirror 12"
RequestHeader unset MirrorID
    


    
    Dans cet ordre, l'en-tête MirrorID n'est pas défini.
    Si l'ordre des directives était inversé, l'en-tête
    MirrorID serait défini à "mirror 12".
    

    top
    

    

    Traitement précoce et traitement
tardif
    
    
    mod_headers peut agir soir précocement, soit
    tardivement au niveau de la requête. Le mode normal est le mode
    tardif, lorsque les en-têtes de requête sont définis, immédiatement
    avant l'exécution du générateur de contenu, et pour les en-têtes de
    réponse, juste au moment où la réponse est envoyée sur le réseau.
    Utilisez toujours le mode tardif sur un serveur en production.
    

    
    Le mode précoce a été conçu à des fins d'aide aux tests et au
    débogage pour les développeurs. Les directives définies en utilisant
    le mot-clé early sont censées agir au tout début du
    traitement de la requête. Cela signifie que l'on peut les utiliser
    pour simuler différentes requêtes et définir des situations de test,
    tout en gardant à l'esprit que les en-têtes peuvent être modifiés à
    tout moment par d'autres modules avant que le réponse ne soit
    générée.
    

    
    Comme les directives précoces sont traitées avant que le
    chemin de la requête ne soit parcouru, les en-têtes
    précoces ne peuvent être définis que dans un contexte de serveur
    principal ou de serveur virtuel. Les directives précoces ne peuvent
    pas dépendre d'un chemin de requête, si bien qu'elles échoueront
    dans des contextes tels que <Directory> ou <Location>.
    

    top
    

    

    Exemples
    

    
      
      
    1. 
        Copie tous les en-têtes de requête qui commencent par "TS" vers
	les en-têtes de la réponse :

        
      Header echo ^TS
      

      
      2. 

      
    2. 
        Ajoute à la réponse un en-tête, mon-en-tête, qui
	contient un horodatage permettant de déterminer le moment où la
	requête a été reçue, et le temps qui s'est écoulé jusqu'à ce que
	la requête ait commencé à être servie. Cet en-tête peut être
	utilisé par le client pour estimer la charge du serveur ou
	isoler les goulets d'étranglement entre le client et le
	serveur.

        
      Header set mon-en-tête "%D %t"
      


        
      le résultat est l'ajout à la réponse d'un en-tête du type :
      

        
      
          mon-en-tête: D=3775428 t=991424704447256
        
      
      
      3. 

      
    3. 
        Dit Bonjour à Joe

        
      
          Header set mon-en-tête "Bonjour Joe. Il a fallu %D microsecondes \
      
          à Apache pour servir cette requête."
        
      

        
      le résultat est l'ajout à la réponse d'un en-tête du type :
      

        
      	Header set MyHeader "Bonjour Joe. Il a fallu D=3775428 microsecondes à Apache
          pour servir cette requête."
      

      
      4. 

      
    4. 
        Ajoute l'en-tête mon-en-tête à la réponse si et
	seulement si l'en-tête mon-en-tête-requête est
	présent dans la requête. Ceci peut s'avérer utile pour générer
	des en-têtes de réponse "à la tête du client". Notez que cet
	exemple nécessite les services du module
	mod_setenvif.

        
      SetEnvIf MyRequestHeader myvalue HAVE_MyRequestHeader
Header set MyHeader "%D %t mytext" env=HAVE_MyRequestHeader
      


        
      Si l'en-tête mon-en-tête-requête: mavaleur est
	présent dans la requête HTTP, la réponse contiendra un en-tête
	du type :
      

        
      
          mon-en-tête: D=3775428 t=991424704447256 montexte
        
      
      
      5. 

      
    5. 
        Permet à DAV de fonctionner avec Apache sur SSL (voir la description
	du problème) en remplaçant https: par
	http: dans l'en-tête Destination :

        
      RequestHeader edit Destination ^https: http: early
      

      
      6. 

      
    6. 
        Définit la valeur d'un même en-tête sous de multiples conditions
	non exclusives, mais ne duplique pas une valeur déjà définie
	dans l'en-tête qui en résulte. Si toutes les conditions
	suivantes sont satisfaites pour une requête (en d'autres termes,
	si les trois variables d'environnement CGI,
	NO_CACHE et NO_STORE existent pour la
	requête) :

        
      Header merge Cache-Control no-cache env=CGI
Header merge Cache-Control no-cache env=NO_CACHE
Header merge Cache-Control no-store env=NO_STORE
      


        
      alors, la réponse contiendra l'en-tête suivant :
      

        
      
          Cache-Control: no-cache, no-store
        
      

        
      Si append avait été utilisé à la place de
	merge, la réponse aurait contenu l'en-tête suivant
	:
      

        
      
          Cache-Control: no-cache, no-cache, no-store
        
      
      
      7. 
      
    7. 
        Définit un cookie de test si et seulement si le client n'envoie
	pas de cookie
        
      Header set Set-Cookie testcookie "expr=-z %{req:Cookie}"
      

      
      8. 
      
    8. 
        Ajoute un en-tête de mise en cache pour les réponses avec un
	code d'état HTTP de 200
        
      Header append Cache-Control s-maxage=600 "expr=%{REQUEST_STATUS} == 200"

    Compatibilité:SetIfEmpty est disponible depuis la version 2.4.7 du
serveur HTTP Apache ; le paramètre expr=valeur a été introduit avec la
version 2.4.10
    

    
    
    Cette directive permet de remplacer, fusionner, ou
    supprimer des en-têtes de réponse HTTP. L'en-tête est modifié juste
    après que le gestionnaire de contenu et les filtres en sortie ne
    s'exécutent, ce qui permet la modification des en-têtes
    sortants.
    

    
    L'argument optionnel condition permet de déterminer
    sur quelle table interne d'en-têtes de réponses cette directive va
    opérer : onsuccess (valeur par défaut, peut être omis) ou
    always. A la différence de ceux de la première table, les
    en-têtes de la seconde sont ajoutés à la réponse même en cas d'erreur et
    sont conservés au fil des redirections internes (par exemple les
    gestionnaires ErrorDocument). Notez aussi que la répétition
    de cette directive avec les deux conditions peut être pertinente
    dans certains scénarios, car always n'englobe pas
    onsuccess en ce qui concerne les en-têtes existants :
    

    
      
       
    • Vous ajoutez un en-tête à une réponse
       générée localement et échouée (non-2xx),
       une redirection par exemple, et dans ce cas, seule la table
       correspondant à always est utilisée dans la réponse
       définitive.
      • 
       
    • Vous modifiez ou supprimez un en-tête généré par un script CGI ou par
       mod_proxy_fcgi, auquel cas, les en-têtes des scripts CGI
       sont dans la table correspondant à always et non dans la
       table par défaut.
      • 
       
    • Vous modifiez ou supprimez un en-tête généré par tel ou tel
       composant du serveur, mais cet en-tête n'est pas trouvé par la
       condition par défaut onsuccess.
      • 
    
    

    
    Comme il n'y a pas de liste unique "normalisée" d'en-têtes, la manière
    dont httpd stocke en interne les en-têtes des réponses HTTP est à l'origine
    de la fonctionnalité que constitue la différence entre
    onsuccess et always. Si vous ne gardez pas à
    l'esprit le concept ci-après lors de l'écriture de votre configuration,
    certaines réponses HTTP pourront contenir des en-têtes dupliqués
    (ce qui pourra dérouter les utilisateurs ou même parfois les clients HTTP). Supposons par
    exemple que votre configuration comporte un mandataire PHP simple avec
    mod_proxy_fcgi et que votre script PHP d'arrière-plan
    ajoute l'en-tête X-Foo: bar à chaque réponse HTTP. Comme décrit
    plus haut, mod_proxy_fcgi utilise la table
    always pour stocker les en-têtes, et une configuration comme la
    suivante n'aboutira pas au résultat attendu car l'en-tête sera dupliqué
    avec les deux valeurs :
    

    
    # la valeur de X-Foo est définie dans la table d'en-têtes 'onsuccess'
Header set X-Foo: baz
    
    

    
    Plusieurs modèles de configuration permettent de contourner ce problème,
    comme celui-ci :
    

        
    # 'onsuccess' peut être omis car il s'agit de la valeur par défaut
Header onsuccess unset X-Foo
Header always set X-Foo "baz"
    


    
    Outre le paramètre condition décrit ci-dessus, vous
    pouvez limiter une action en fonction de codes d'état HTTP, par
    exemple pour les requêtes mandatées ou générées par un programme
    CGI. Voir l'exemple qui utilise %{REQUEST_STATUS} dans la section
    ci-dessus.
    

    
    L'action que cette directive provoque est déterminée par le
    premier argument (ou par le second argument si une
    condition est spécifiée). Il peut prendre
    une des valeurs suivantes :
    

    
    Avertissement
    
        
    Vous devez lire la différence, décrite plus haut, entre les listes
	d'en-têtes always et onsuccess avant de lire
	la liste d'actions ci-dessous car cet important concept s'applique
	encore ici. En fait, chaque action fonctionne telle qu'elle est décrite
	mais seulement pour la liste d'en-têtes cible.
    
    
    

    
    
    
    add
    
    
    L'en-tête est ajouté au jeu d'en-têtes préexistant, même s'il
    existe déjà. Ceci peut conduire à la présence de deux (ou plusieurs)
    en-têtes possèdant le même nom et donc induire des conséquences
    imprévues ; en général, il est préférable d'utiliser
    set, append ou merge.
    

    
    append
    
    
    La valeur d'en-tête est ajoutée à tout en-tête existant de même
    nom. Lorsqu'une nouvelle valeur est ainsi ajoutée, elle est séparée
    de celles qui sont déjà présentes par une virgule. Il s'agit de la
    méthode HTTP standard permettant d'affecter plusieurs valeurs à un
    en-tête.
    

    
    echo
    
    
    Les en-têtes de la requête possédant le nom spécifié sont
    recopiés vers les en-têtes de la réponse. en-tête peut
    être une expression rationnelle, et
    valeur ne doit pas être présent.
    

    
    edit
    
    
    edit*
    
    
    Si l'en-tête existe, sa valeur est modifiée en fonction d'une
    expression rationnelle de type
    recherche/remplacement. L'argument valeur est une
    expression rationnelle, et
    l'argument remplacement une chaîne de caractères de
    remplacement qui peut contenir des références
    arrières ou des spécificateurs de format. La forme edit n'effectuera une
    recherche/remplacement qu'une seule fois dans la valeur de
    l'en-tête, alors que la forme edit* en effectuera autant
    que le nombre d'apparition de la chaîne à remplacer.
    

    
    merge
    
    
    La valeur d'en-tête est ajoutée à tout en-tête de même nom, sauf
    si elle apparaît déjà dans la liste des valeurs préexistantes de
    l'en-tête séparées par des virgules. Lorsqu'une nouvelle valeur est
    ainsi ajoutée, elle est séparée de celles qui sont déjà présentes
    par une virgule. Il s'agit de la méthode HTTP standard permettant
    d'affecter plusieurs valeurs à un en-tête. Les valeurs sont
    comparées en tenant compte de la casse, et après le traitement de
    tous les spécificateurs de format. Une valeur entourée de guillemets
    est considérée comme différente de la même valeur mais sans
    guillemets.
    

    
    set
    
    
    L'en-tête est défini, remplaçant tout en-tête préexistant avec
    le même nom. L'argument valeur peut être une chaîne de
    formatage.
    

    
    setifempty
    
    
    L'en-tête est défini, mais seulement s'il n'existe
    aucun en-tête avec le même nom.
    
    
    L'en-tête Content-Type est un cas particulier car il est possible que sa
    valeur ait été déterminée mais que l'en-tête ne soit pas présent dans la
    réponse lorsque setifempty est évalué. Dans ce cas, il est
    préférable d'utiliser set comme dans l'exemple suivant :
    
    Header set Content-Type "text/plain" "expr=-z %{CONTENT_TYPE}"
    

    
    

    
    unset
    
    
    L'en-tête est supprimé s'il existe. Si plusieurs en-têtes
    possèdent le même nom, ils seront tous supprimés. L'argument
    value ne doit pas apparaître.
    

    
    note
    
    
    La valeur de l'en-tête considéré est copiée dans une
    note interne dont le nom est spécifié via l'argument
    valeur. Ceci permet de journaliser la valeur d'un en-tête
    envoyé par un programme CGI ou une ressource mandatée, même s'il
    est prévu de l'effacer.
    
    Disponible à partir de la version 2.4.7 du serveur HTTP Apache.
    

    
        

    
    Cet argument est suivi d'un nom d'en-tête qui peut se
    terminer par un caractère ':', mais ce n'est pas obligatoire. La
    casse est ignorée avec set, append,
    merge, add, unset et
    edit. Le nom d'en-tête est sensible à la
    casse pour echo et peut être une expression rationnelle.
    

    
    Avec set, append, merge et
    add, une valeur est spécifiée comme
    argument suivant. Si valeur contient des espaces, elle
    doit être entourée de guillemets. valeur peut être une
    chaîne de caractères, une chaîne contenant des spécificateurs de
    format propres à mod_headers (et des caractères
    littéraux), ou une expression  ap_expr
    préfixée par expr=.
    
    
    
    valeur supporte les spécificateurs de format suivants :
    

    
    FormatDescription
    

    %%
        Le caractère pourcentage
    

    %t
        Le moment de réception de la requête en temps
	universel coordonné depuis le temps epoch (Jan. 1, 1970) et
	exprimé en microsecondes. La valeur est précédée de
	t=.
    

    %D
        Le temps écoulé entre la réception de la requête et l'envoi
	des en-têtes sur le réseau. Il s'agit de la durée de traitement
	de la requête. La valeur est précédée de D=. La
	valeur est exprimée en microsecondes.
    

    %l
        La charge moyenne courante du serveur proprement dit. Ce
	sont les valeurs obtenues par getloadavg() qui
	représentent la charge moyenne courante, sur 5 minutes et sur 15
	minutes. Chaque valeur est précédée de l= et
	séparée de la suivante par un /.
    
	Disponible depuis la version 2.4.4 du serveur HTTP Apache.
        
    

    %i
        Le pourcentage courant de httpd au repos (de 0 à 100)
	en se basant sur le nombre de processus et threads disponibles.
	La valeur est précédée de i=.
    
	Disponible depuis la version 2.4.4 du serveur HTTP Apache.
        
    

    %b
        Le pourcentage courant de httpd utilisé (de 0 à 100)
	en se basant sur le nombre de processus et threads disponibles.
	La valeur est précédée de b=.
    
	Disponible depuis la version 2.4.4 du serveur HTTP Apache.
        
    

    %{NOM_VARIABLE}e
        Le contenu de la variable
	d'environnement NOM_VARIABLE.
    

    %{NOM_VARIABLE}s
        Le contenu de la variable
	d'environnement SSL NOM_VARIABLE, si
	mod_ssl est activé.
    

    

    
    Note
    
      
    Le spécificateur de format %s est disponible
      depuis la version 2.1 d'Apache ; il peut être utilisé à la place
      de %e pour éviter de devoir spécifier
      SSLOptions +StdEnvVars. Cependant, si
      SSLOptions +StdEnvVars doit tout de même être
      spécifié pour une raison quelconque, %e sera plus
      efficace que %s.
    
    
    

    
    Note à propos des valeurs des expressions
    
    
    Lorsque le paramètre valeur utilise l'interpréteur ap_expr, certaines syntaxes d'expressions
    seront différentes des exemples qui évaluent des expressions
    booléennes telles que <If> :
    
    
      
      
    • Le point de départ de la syntaxe est 'string' au lieu de
      'expr'.
      • 
      
    • Les appels de fonction utilisent la syntaxe %{funcname:arg} au
      lieu de funcname(arg).
      • 
      
    • Les fonctions multi-arguments ne sont pas encore disponibles
      depuis le point de départ 'string'.
      • 
      
    • Il faut mettre entre guillemets l'ensemble du paramètre, comme
      dans l'exemple suivant : 
          
      Header set foo-checksum "expr=%{md5:foo}"
      

       
      • 
                   
    
    
    
    

    
    editnécessite les deux arguments
    valeur, qui est une expression
    rationnelle, et une chaîne additionnelle
    remplacement. Depuis la version 2.4.7, la chaîne de
    remplacement peut aussi
    contenir des spécificateurs de format.
    

    
    La directive Header peut être suivie d'un
    argument additionnel qui peut prendre les valeurs suivantes :
    

    
    
    
    early
    
    
    Spécifie traitement préalable.
    
    
    env=[!]variable
    
    
    La directive est appliquée si et seulement si la variable d'environnement
    variable existe. Un ! devant
    variable inverse le test, et la directive ne
    s'appliquera alors que si variable n'est pas définie.
    
    
    expr=expression
    
    
    La directive s'applique si et seulement si expression
    est évaluée à true. Vous trouverez plus de détails à propos de la
    syntaxe et de l'évaluation des expressions dans la documentation ap_expr.
    
             # Cet exemple retarde l'évaluation de la clause de condition par
	 # rapport à <If>
         Header always set CustomHeader my-value "expr=%{REQUEST_URI} =~ m#^/special_path.php$#"
    

    
    
    
    

    
    Excepté le cas du mode précoce, les
    directives Header sont traitées juste avant
    l'envoi de la réponse sur le réseau. Cela signifie qu'il est
    possible de définir et/ou modifier la plupart des en-têtes, à
    l'exception de certains en-têtes qui sont ajoutés par le filtre
    d'en-tête HTTP. Avant la version 2.2.12, il n'était pas
    possible de modifier l'en-tête Content-Type avec cette directive.

    Directive RequestHeader
    

    

    Description:Configure les en-têtes d'une requête HTTP
    

    Syntaxe:RequestHeader add|append|edit|edit*|merge|set|setifempty|unset
en-tête [[expr=]valeur
[remplacement]

    Surcharges autorisées:FileInfo
    

    Statut:Extension
    

    Module:mod_headers
    

    Compatibilité:SetIfEmpty est disponible depuis la version 2.4.7 du
serveur HTTP Apache ; le paramètre expr=valeur a été introduit avec la
version 2.4.10
    

    
    
    Cette directive permet de remplacer, fusionner, modifier ou
    supprimer des en-têtes de requête HTTP. L'en-tête est modifié juste
    avant que le gestionnaire de contenu ne s'exécute, ce qui permet la
    modification des en-têtes entrants. L'action effectuée est
    déterminée par le premier argument. Ce dernier accepte les valeurs
    suivantes :
    

    
    

    
    add
    
    
    L'en-tête est ajouté au jeu d'en-têtes préexistant, même s'il
    existe déjà. Ceci peut conduire à la présence de deux (ou plusieurs)
    en-têtes possèdant le même nom et donc induire des conséquences
    imprévues ; en général, il est préférable d'utiliser
    set, append ou merge.
    

    
    append
    
    
    La valeur d'en-tête est ajoutée à tout en-tête existant de même
    nom. Lorsqu'une nouvelle valeur est ainsi ajoutée, elle est séparée
    de celles qui sont déjà présentes par une virgule. Il s'agit de la
    méthode HTTP standard permettant d'affecter plusieurs valeurs à un
    en-tête.
    

    
    edit
    
    
    edit*
    
    
    Si l'en-tête existe, sa valeur est modifiée en fonction d'une
    expression rationnelle de type
    recherche/remplacement. L'argument valeur est une
    expression rationnelle, et
    l'argument remplacement une chaîne de caractères de
    remplacement qui peut contenir des références
    arrières ou des spécificateurs de format. Avec
    edit, la chaîne de l'en-tête correspondant au modèle ne
    sera recherchée et remplacée qu'une seule fois, alors qu'avec
    edit*, elle le sera pour chacune de ses instances si
    elle apparaît plusieurs fois.
    

    
    merge
    
    
    La valeur d'en-tête est ajoutée à tout en-tête de même nom, sauf
    si elle apparaît déjà dans la liste des valeurs préexistantes de
    l'en-tête séparées par des virgules. Lorsqu'une nouvelle valeur est
    ainsi ajoutée, elle est séparée de celles qui sont déjà présentes
    par une virgule. Il s'agit de la méthode HTTP standard permettant
    d'affecter plusieurs valeurs à un en-tête. Les valeurs sont
    comparées en tenant compte de la casse, et après le traitement de
    tous les spécificateurs de format. Une valeur entourée de guillemets
    est considérée comme différente de la même valeur mais sans
    guillemets.
    

    
    set
    
    
    L'en-tête est défini, remplaçant tout en-tête préexistant avec
    le même nom.
    

    
    setifempty
    
    
    L'en-tête est défini, mais seulement s'il n'existe
    aucun en-tête avec le même nom.
    
    Disponible depuis la version 2.4.7 du serveur HTTP Apache.
    

    
    unset
    
    
    L'en-tête est supprimé s'il existe. Si plusieurs en-têtes
    possèdent le même nom, ils seront tous supprimés. L'argument
    value ne doit pas apparaître.
    
    
    

    
    Cet argument est suivi d'un nom d'en-tête qui peut se terminer
    par un caractère ':', mais ce n'est pas obligatoire. La casse est
    ignorée. Avec set, append,
    merge et add, une valeur est
    fournie en troisième argument. Si une valeur contient des
    espaces, elle doit être entourée de guillemets. Avec
    unset, aucune valeur ne doit apparaître.
    valeur peut être une chaîne de caractères, une chaîne
    contenant des spécificateurs de format, ou une combinaison des deux.
    Les spécificateurs de format supportés sont les mêmes que ceux de la
    directive Header, à
    laquelle vous pouvez vous reporter pour plus de détails. Avec
    edit, les deux arguments valeur et
    remplacement sont obligatoires, et correspondent
    respectivement à une expression
    rationnelle et à une chaîne de remplacement.
    

    
    La directive RequestHeader peut être
    suivie d'un argument supplémentaire, qui pourra prendre les valeurs
    suivantes :
    
    
    
    
    early
    
    
    Spécifie traitement préalable.
    
    
    env=[!]variable
    
    
    La directive est appliquée si et seulement si la variable d'environnement
    variable existe. Un ! devant
    variable inverse le test, et la directive ne
    s'appliquera alors que si variable n'est pas définie.
    
    
    expr=expression
    
    
    La directive s'applique si et seulement si expression
    est évaluée à true. Vous trouverez plus de détails à propos de la
    syntaxe et de l'évaluation des expressions dans la documentation ap_expr.
    
    
    

    
    Excepté le cas du mode précoce, la directive
    RequestHeader est traitée juste avant la
    prise en compte de la requête par son gestionnaire, au cours de la
    phase de vérification. Ceci permet la modification des en-têtes
    générés par le navigateur, ou par les filtres en entrée
    d'Apache.

    Module Apache mod_slotmem_shm
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Fournisseur de mémoire partagée basée sur les
slots.
    

    Statut:Extension
    

    Identificateur de Module:slotmem_shm_module
    

    Fichier Source:mod_slotmem_shm.c
    

    Sommaire
    

    
    mod_slotmem_shm est un fournisseur de mémoire qui
    permet la création et l'accès à un segment de mémoire partagée dans
    lequel les ensembles de données sont organisés en "slots".
    
    

    
    L'ensemble de la mémoire partagée est effacé à chaque
    redémarrage, que ce dernier soit graceful ou non. Les données sont
    stockées et restituées dans/à partir d'un fichier défini par le
    paramètre name des appels create et
    attach. Si son chemin absolu n'est pas spécifié, le
    chemin du fichier sera relatif au chemin défini par la directive
    DefaultRuntimeDir.
    
    

    
    mod_slotmem_shm fournit les fonctions d'API suivantes
    :
    
    


    /* appelle le callback pour tous les slots actifs */
apr_status_t doall(ap_slotmem_instance_t *s, ap_slotmem_callback_fn_t *func, void *data, apr_pool_t *pool)

/* crée un nouveau slot de mémoire dont chaque taille d'item est
      item_size. 'name' est utilisé pour générer le nom du fichier
      permettant de stocker/restaurer le contenu de la mémoire partagée,
      si elle est configurée. Les valeurs possibles sont :
      "none"                - Mémoire partagée anonyme et pas de stockage permanent
      "file-name"           - [DefaultRuntimeDir]/file-name
      "/absolute-file-name" - Chemin absolu du fichier */
apr_status_t create(ap_slotmem_instance_t **new, const char *name, apr_size_t item_size, unsigned int item_num, ap_slotmem_type_t type, apr_pool_t *pool)

/* attache à un slot de mémoire existant. Voir
      'create' pour la description du paramètre
      'name'. */
apr_status_t attach(ap_slotmem_instance_t **new, const char *name, apr_size_t *item_size, unsigned int *item_num, apr_pool_t *pool)

/* obtient la mémoire associée à ce slot actif. */
apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void **mem)

/* lit la mémoire depuis ce slot et la transfert vers dest */
apr_status_t get(ap_slotmem_instance_t *s, unsigned int item_id, unsigned char *dest, apr_size_t dest_len)

/* écrit dans ce slot la mémoire en provenance de src */
apr_status_t put(ap_slotmem_instance_t *slot, unsigned int item_id, unsigned char *src, apr_size_t src_len)

/* renvoie le nombre total de slots contenus dans ce segment */
unsigned int num_slots(ap_slotmem_instance_t *s)

/* renvoie la taille totale des données, en octets, contenues
      dans un slot de ce segment */
apr_size_t slot_size(ap_slotmem_instance_t *s)

/* alloue le premier slot libre et le marque comme utilisé (n'effectue aucune
      copie de données) */
apr_status_t grab(ap_slotmem_instance_t *s, unsigned int *item_id)

/* appropriation ou allocation forcée du slot spécifié et marquage comme
      utilisé (n'effectue aucune copie de données) */
apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id)

/* libère un slot et le marque comme non utilisé (n'effectue aucune
      copie de données) */
apr_status_t release(ap_slotmem_instance_t *s, unsigned int item_id)

    Cette directive fait en sorte que le serveur effectue un
    chroot(8) vers le répertoire spécifié après le démarrage,
    mais avant d'accepter les requêtes en provenance du réseau.
    
    
    Notez que l'exécution du serveur dans un environnement chroot
    n'est pas simple et nécessite une configuration particulière, en
    particulier si vous utilisez des scripts CGI ou PHP. Il est
    conseillé de se familiariser avec l'opération chroot avant d'essayer
    d'utiliser cette fonctionnalité.

    La directive Group permet de définir le
    groupe sous lequel le serveur va traiter les requêtes. Pour
    utiliser cette directive, le serveur doit avoir été démarré par
    root. Si vous démarrez le serveur en tant
    qu'utilisateur non root, celui-ci ne pourra pas adopter le groupe
    spécifié comme groupe d'exécution, et continuera à s'exécuter sous
    le groupe de l'utilisateur qui l'aura lancé. groupe unix
    peut se présenter sous la forme :
    

    
    
      
    d'un nom de groupe
    
      
    Référence le groupe spécifié par son nom.
    

      
    du caractère # suivi d'un numéro de groupe.
    
      
    Référence le groupe spécifié par son numéro.
    
    
    

    
    Exemple
    Group www-group
    

    

    
    Il est conseillé de créer un groupe dédié à l'exécution du
    serveur. Certains administrateurs utilisent l'utilisateur
    nobody, mais ce n'est pas toujours souhaitable ou même
    possible.

    La directive User permet de définir
    l'utilisateur sous lequel le serveur va traiter les requêtes. Pour
    utiliser cette directive, le serveur doit avoir été démarré
    par root. Si vous démarrez le serveur en tant
    qu'utilisateur non root, celui-ci ne pourra pas adopter
    l'utilisateur avec privilèges restreints comme utilisateur
    d'exécution, et continuera à s'exécuter sous
    l'utilisateur qui l'aura lancé. Si vous démarrez le serveur en tant
    que root, il est normal que le processus parent
    continue à s'exécuter sous root. utilisateur unix peut se
    présenter sous la forme :

    le caractère # suivi d'un numéro d'utilisateur.
    
      
    Référence l'utilisateur spécifié par son numéro.
    
    
    

    
    L'utilisateur ne doit pas posséder de privilèges qui lui
    permettraient d'accéder à des fichiers non destinés au
    monde extérieur, et parallèlement, l'utilisateur ne doit pas
    exécuter de code dont l'usage soit destiné à un usage autre que les
    requêtes HTTP. Il est conseillé de créer un utilisateur et un groupe
    dédiés à l'exécution du serveur. Certains administrateurs utilisent
    l'utilisateur nobody, mais ce n'est pas toujours
    souhaitable, car l'utilisateur nobody peut avoir
    diverses utilisations dans le système.

    Sommaire
    


    Le module mod_watchdog définit des
branchements (hooks) programmés pour permettre à d'autres modules
d'exécuter des tâches périodiques. Ces modules peuvent enregistrer des
gestionnaires (handlers) pour les branchements de
mod_watchdog. Actuellement, seuls les modules suivants
de la distribution Apache utilisent cette fonctionnalité :
    


    
Pour qu'un module puisse utiliser la fonctionnalité de
mod_watchdog, ce dernier doit être lié statiquement
avec le serveur httpd ; s'il a été lié dynamiquement, il doit être
chargé avant l'appel au module qui doit utiliser sa fonctionnalité.

    AcceptFilter Directive
    

    

    Description:Configures optimizations for a Protocol's Listener Sockets
    

    Syntax:AcceptFilter protocol accept_filter
    

    Context:server config
    

    Status:Core
    

    Module:core
    

    
    
    This directive enables operating system specific optimizations for a
       listening socket by the Protocol type.
       The basic premise is for the kernel to not send a socket to the server
       process until either data is received or an entire HTTP Request is buffered.
       Only 
       FreeBSD's Accept Filters, Linux's more primitive
       TCP_DEFER_ACCEPT, and Windows' optimized AcceptEx()
       are currently supported.
    

    
    Using none for an argument will disable any accept filters
       for that protocol.  This is useful for protocols that require a server
       send data first, such as ftp: or nntp:
    
    
    AcceptFilter nntp none
    


    
    The default protocol names are https for port 443
       and http for all other ports.  To specify that another
       protocol is being used with a listening port, add the protocol
       argument to the Listen
       directive.
    

    
    The default values on FreeBSD are:
    
    
    AcceptFilter http httpready
AcceptFilter https dataready
    


    
    The httpready accept filter buffers entire HTTP requests at
       the kernel level.  Once an entire request is received, the kernel then
       sends it to the server. See the
       
       accf_http(9) man page for more details.  Since HTTPS requests are
       encrypted, only the 
       accf_data(9) filter is used.
    

    
    The default values on Linux are:
    
    
    AcceptFilter http data
AcceptFilter https data
    


    
    Linux's TCP_DEFER_ACCEPT does not support buffering http
       requests.  Any value besides none will enable
       TCP_DEFER_ACCEPT on that listener. For more details
       see the Linux
       
       tcp(7) man page.
    

    
    The default values on Windows are:
    
    
    AcceptFilter http connect
AcceptFilter https connect
    


    
    Window's mpm_winnt interprets the AcceptFilter to toggle the AcceptEx()
       API, and does not support http protocol buffering. connect
       will use the AcceptEx() API, also retrieve the network endpoint
       addresses, but like none the connect option
       does not wait for the initial data transmission.
    

    
    On Windows, none uses accept() rather than AcceptEx()
       and will not recycle sockets between connections.  This is useful for
       network adapters with broken driver support, as well as some virtual
       network providers such as vpn drivers, or spam, virus or spyware
       filters.
    

    
    
      
    The data AcceptFilter (Windows)
    

      
    For versions 2.4.23 and prior, the Windows data accept
         filter waited until data had been transmitted and the initial data
         buffer and network endpoint addresses had been retrieved from the
         single AcceptEx() invocation. This implementation was subject to a
         denial of service attack and has been disabled.
    

      
    Current releases of httpd default to the connect filter
         on Windows, and will fall back to connect if
         data is specified. Users of prior releases are encouraged
         to add an explicit setting of connect for their
         AcceptFilter, as shown above.

    AcceptPathInfo Directive
    

    

    Description:Resources accept trailing pathname information
    

    Syntax:AcceptPathInfo On|Off|Default
    

    Default:AcceptPathInfo Default
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Core
    

    Module:core
    

    

    
    This directive controls whether requests that contain trailing
    pathname information that follows an actual filename (or
    non-existent file in an existing directory) will be accepted or
    rejected.  The trailing pathname information can be made
    available to scripts in the PATH_INFO environment
    variable.
    

    
    For example, assume the location /test/ points to
    a directory that contains only the single file
    here.html.  Then requests for
    /test/here.html/more and
    /test/nothere.html/more both collect
    /more as PATH_INFO.
    

    
    The three possible arguments for the
    AcceptPathInfo directive are:
    
    
    
    
    Off
    A request will only be accepted if it
    maps to a literal path that exists.  Therefore a request with
    trailing pathname information after the true filename such as
    /test/here.html/more in the above example will return
    a 404 NOT FOUND error.
    

    
    On
    A request will be accepted if a
    leading path component maps to a file that exists.  The above
    example /test/here.html/more will be accepted if
    /test/here.html maps to a valid file.
    

    
    Default
    The treatment of requests with
    trailing pathname information is determined by the handler responsible for the request.
    The core handler for normal files defaults to rejecting
    PATH_INFO requests. Handlers that serve scripts, such as cgi-script and isapi-handler, generally accept
    PATH_INFO by default.
    
    
    

    
    The primary purpose of the AcceptPathInfo
    directive is to allow you to override the handler's choice of
    accepting or rejecting PATH_INFO. This override is required,
    for example, when you use a filter, such
    as INCLUDES, to generate content
    based on PATH_INFO.  The core handler would usually reject
    the request, so you can use the following configuration to enable
    such a script:
    

    
    <Files "mypaths.shtml">
  Options +Includes
  SetOutputFilter INCLUDES
  AcceptPathInfo On
</Files>

    AccessFileName Directive
    

    

    Description:Name of the distributed configuration file
    

    Syntax:AccessFileName filename [filename] ...
    

    Default:AccessFileName .htaccess
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    While processing a request, the server looks for
    the first existing configuration file from this list of names in
    every directory of the path to the document, if distributed
    configuration files are enabled for that
    directory. For example:
    

    
    AccessFileName .acl
    


    
    Before returning the document
    /usr/local/web/index.html, the server will read
    /.acl, /usr/.acl,
    /usr/local/.acl and /usr/local/web/.acl
    for directives unless they have been disabled with:
    

    
    <Directory "/">
    AllowOverride None
</Directory>

    AddDefaultCharset Directive
    

    

    Description:Default charset parameter to be added when a response
content-type is text/plain or text/html
    

    Syntax:AddDefaultCharset On|Off|charset
    

    Default:AddDefaultCharset Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Core
    

    Module:core
    

    
    
    This directive specifies a default value for the media type
    charset parameter (the name of a character encoding) to be added
    to a response if and only if the response's content-type is either
    text/plain or text/html.  This should override
    any charset specified in the body of the response via a META
    element, though the exact behavior is often dependent on the user's client
    configuration. A setting of AddDefaultCharset Off
    disables this functionality. AddDefaultCharset On enables
    a default charset of iso-8859-1. Any other value is assumed
    to be the charset to be used, which should be one of the
    IANA registered
    charset values for use in Internet media types (MIME types).
    For example:
    

    
    AddDefaultCharset utf-8
    


    
    AddDefaultCharset should only be used when all
    of the text resources to which it applies are known to be in that
    character encoding and it is too inconvenient to label their charset
    individually. One such example is to add the charset parameter
    to resources containing generated content, such as legacy CGI
    scripts, that might be vulnerable to cross-site scripting attacks
    due to user-provided data being included in the output.  Note, however,
    that a better solution is to just fix (or delete) those scripts, since
    setting a default charset does not protect users that have enabled
    the "auto-detect character encoding" feature on their browser.

    AllowEncodedSlashes Directive
    

    

    Description:Determines whether encoded path separators in URLs are allowed to
be passed through
    

    Syntax:AllowEncodedSlashes On|Off|NoDecode
    

    Default:AllowEncodedSlashes Off
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    Compatibility:
NoDecode option available in 2.3.12 and later.
    

    
    
    The AllowEncodedSlashes directive allows URLs
    which contain encoded path separators (%2F for /
    and additionally %5C for \ on accordant systems)
    to be used in the path info.
    

    
    With the default value, Off, such URLs are refused
    with a 404 (Not found) error.
    

    
    With the value On, such URLs are accepted, and encoded
      slashes are decoded like all other encoded characters.
    

    
    With the value NoDecode, such URLs are accepted, but
      encoded slashes are not decoded but left in their encoded state.
    

    
    Turning AllowEncodedSlashes On is
    mostly useful when used in conjunction with PATH_INFO.
    

    
    Note
    
      
    If encoded slashes are needed in path info, use of NoDecode is
      strongly recommended as a security measure.  Allowing slashes
      to be decoded could potentially allow unsafe paths.

    AllowOverride Directive
    

    

    Description:Types of directives that are allowed in
.htaccess files
    

    Syntax:AllowOverride All|None|directive-type
[directive-type] ...
    

    Default:AllowOverride None (2.3.9 and later), AllowOverride All (2.3.8 and earlier)
    

    Context:directory
    

    Status:Core
    

    Module:core
    

    
    
    When the server finds an .htaccess file (as
    specified by AccessFileName),
    it needs to know which directives declared in that file can override
    earlier configuration directives.
    

    
    Only available in <Directory> sections
    
    AllowOverride is valid only in
    <Directory>
    sections specified without regular expressions, not in <Location>, <DirectoryMatch> or
    <Files> sections.
    
    

    
    When this directive is set to None and AllowOverrideList is set to
    None, .htaccess files are
    completely ignored. In this case, the server will not even attempt
    to read .htaccess files in the filesystem.
    

    
    When this directive is set to All, then any
    directive which has the .htaccess Context is allowed in
    .htaccess files.
    

    
    The directive-type can be one of the following
    groupings of directives. (See the override class
    index for an up-to-date listing of which directives are enabled by each
    directive-type.)

      Allow use of AllowOverride option to treat syntax errors in
      .htaccess as nonfatal. Instead of causing an Internal Server
      Error, disallowed or unrecognised directives will be ignored
      and a warning logged:
      
      
          
    • Nonfatal=Override treats directives
              forbidden by AllowOverride as nonfatal.
      • 
          
    • Nonfatal=Unknown treats unknown directives
              as nonfatal.  This covers typos and directives implemented
              by a module that's not present.
      • 
          
    • Nonfatal=All treats both the above as nonfatal.
      • 
      
    
      
    Note that a syntax error in a valid directive will still cause
      an internal server error.
    
      
    Security
    
          Nonfatal errors may have security implications for .htaccess users.
          For example, if AllowOverride disallows AuthConfig, users'
          configuration designed to restrict access to a site will be disabled.
      
    
      
    

      
    Options[=Option,...]
    

      
    
      Allow use of the directives controlling specific directory
      features (Options and
      XBitHack).
      An equal sign may be given followed by a comma-separated list, without
      spaces, of options that may be set using the Options command.

      
    Implicit disabling of Options
    
      
    Even though the list of options that may be used in .htaccess files
         can be limited with this directive, as long as any Options directive is allowed any
         other inherited option can be disabled by using the non-relative
         syntax.  In other words, this mechanism cannot force a specific option
         to remain set while allowing any others to be set.
      
    

      
    
      AllowOverride Options=Indexes,MultiViews
      
    
      
    
    
    

    
    Example:
    

    
    AllowOverride AuthConfig Indexes
    


    
    In the example above, all directives that are neither in the group
    AuthConfig nor Indexes cause an internal
    server error.
    

    
    For security and performance reasons, do not set
    AllowOverride to anything other than None
    in your <Directory "/"> block. Instead, find (or
    create) the <Directory> block that refers to the
    directory where you're actually planning to place a
    .htaccess file.

    AllowOverrideList Directive
    

    

    Description:Individual directives that are allowed in
.htaccess files
    

    Syntax:AllowOverrideList None|directive
[directive-type] ...
    

    Default:AllowOverrideList None
    

    Context:directory
    

    Status:Core
    

    Module:core
    

    
    
    When the server finds an .htaccess file (as
    specified by AccessFileName),
    it needs to know which directives declared in that file can override
    earlier configuration directives.
    

    
    Only available in <Directory> sections
    
    AllowOverrideList is valid only in
    <Directory>
    sections specified without regular expressions, not in <Location>, <DirectoryMatch> or
    <Files> sections.
    
    

    
    When this directive is set to None and AllowOverride is set to None,
    then .htaccess files are completely
    ignored.  In this case, the server will not even attempt to read
    .htaccess files in the filesystem.
    

    
    Example:
    

    
    AllowOverride None
AllowOverrideList Redirect RedirectMatch
    


    
    In the example above, only the Redirect and
    RedirectMatch directives are allowed. All others will
    cause an internal server error.
    

    
    Example:
    

    
    AllowOverride AuthConfig
AllowOverrideList CookieTracking CookieName
    


    
    In the example above, AllowOverride
     grants permission to the AuthConfig
    directive grouping and AllowOverrideList grants
    permission to only two directives from the FileInfo directive
    grouping. All others will cause an internal server error.

    CGIMapExtension sys:\foo.nlm .foo will
    cause all CGI script files with a .foo extension to
    be passed to the FOO interpreter.

    Status:Core
    

    Module:core
    

    Compatibility:Available in Apache HTTP Server 2.4.13 and later
    

    
    
    CGIPassAuth allows scripts access to HTTP
    authorization headers such as Authorization, which is
    required for scripts that implement HTTP Basic authentication.
    Normally these HTTP headers are hidden from scripts. This is to disallow
    scripts from seeing user ids and passwords used to access the server when
    HTTP Basic authentication is enabled in the web server.  This directive
    should be used when scripts are allowed to implement HTTP Basic
    authentication.
    

    
    This directive can be used instead of the compile-time setting
    SECURITY_HOLE_PASS_AUTHORIZATION which has been available
    in previous versions of Apache HTTP Server.
    

    
    The setting is respected by any modules which use
    ap_add_common_vars(), such as mod_cgi,
    mod_cgid, mod_proxy_fcgi,
    mod_proxy_scgi, and so on.  Notably, it affects
    modules which don't handle the request in the usual sense but
    still use this API; examples of this are mod_include
    and mod_ext_filter.  Third-party modules that don't
    use ap_add_common_vars() may choose to respect the setting
    as well.

    ContentDigest Directive

    Default:ContentDigest Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Core
    

    Module:core
    

    
    
    This directive enables the generation of
    Content-MD5 headers as defined in RFC1864
    respectively RFC2616.
    

    
    MD5 is an algorithm for computing a "message digest"
    (sometimes called "fingerprint") of arbitrary-length data, with
    a high degree of confidence that any alterations in the data
    will be reflected in alterations in the message digest.
    

    
    The Content-MD5 header provides an end-to-end
    message integrity check (MIC) of the entity-body. A proxy or
    client may check this header for detecting accidental
    modification of the entity-body in transit. Example header:
    

    
    
      Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
    
    

    
    Note that this can cause performance problems on your server
    since the message digest is computed on every request (the
    values are not cached).
    

    
    Content-MD5 is only sent for documents served
    by the core, and not by any module. For example,
    SSI documents, output from CGI scripts, and byte range responses
    do not have this header.

    Compatibility:Available in Apache 2.4.2 and later
    

    
    
    The DefaultRuntimeDir directive sets the
    directory in which the server will create various run-time files
    (shared memory, locks, etc.). If set as a relative path, the full path
    will be relative to ServerRoot.
    

    
    Example
    
   
    DefaultRuntimeDir scratch/
    


    
    The default location of DefaultRuntimeDir may be
    modified by changing the DEFAULT_REL_RUNTIMEDIR #define
    at build time.
    

   
    Note: ServerRoot should be specified before this
   directive is used. Otherwise, the default value of ServerRoot
   would be used to set the base directory.

    Module:core
    

    Compatibility:The argument none is available in Apache httpd 2.2.7 and later.  All other choices are DISABLED for 2.3.x and later.
    

    
    
    This directive has been disabled.  For backwards compatibility
    of configuration files, it may be specified with the value
    none, meaning no default media type. For example:
    

    
    DefaultType None
    


    
    DefaultType None is only available in
    httpd-2.2.7 and later.
    

    
    Use the mime.types configuration file and the
    AddType to configure media
    type assignments via file extensions, or the
    ForceType directive to configure
    the media type for specific resources. Otherwise, the server will
    send the response without a Content-Type header field and the
    recipient may attempt to guess the media type.

    In its one parameter form, Define is

    <IfDefine>
    sections without needing to alter -D arguments in any
    startup scripts.
    

    
    In addition to that, if the second parameter is given, a config variable
    is set to this value. The variable can be used in the configuration using
    the ${VAR} syntax. The variable is always globally defined
    and not limited to the scope of the surrounding config section.

    <Directory> Directive
    

    

    Description:Enclose a group of directives that apply only to the
named file-system directory, sub-directories, and their contents.
    

    Syntax:<Directory directory-path>
... </Directory>
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    <Directory> and
    </Directory> are used to enclose a group of
    directives that will apply only to the named directory,
    sub-directories of that directory, and the files within the respective
    directories.  Any directive that is allowed
    in a directory context may be used. Directory-path is
    either the full path to a directory, or a wild-card string using
    Unix shell-style matching. In a wild-card string, ? matches
    any single character, and * matches any sequences of
    characters. You may also use [] character ranges. None
    of the wildcards match a `/' character, so <Directory
    "/*/public_html"> will not match
    /home/user/public_html, but <Directory
    "/home/*/public_html"> will match. Example:
    

    
    <Directory "/usr/local/httpd/htdocs">
  Options Indexes FollowSymLinks
</Directory>
    


    
    Directory paths may be quoted, if you like, however, it
    must be quoted if the path contains spaces. This is because a
    space would otherwise indicate the end of an argument.
    

    
    
      
    Be careful with the directory-path arguments:
      They have to literally match the filesystem path which Apache httpd uses
      to access the files. Directives applied to a particular
      <Directory> will not apply to files accessed from
      that same directory via a different path, such as via different symbolic
      links.
    
    
    

    
    Regular
    expressions can also be used, with the addition of the
    ~ character. For example:
    

    
    <Directory ~ "^/www/[0-9]{3}">

</Directory>
    


    
    would match directories in /www/ that consisted of
    three numbers.
    

    
    If multiple (non-regular expression) <Directory> sections
    match the directory (or one of its parents) containing a document,
    then the directives are applied in the order of shortest match
    first, interspersed with the directives from the .htaccess files. For example,
    with
    

    
    <Directory "/">
  AllowOverride None
</Directory>

<Directory "/home">
  AllowOverride FileInfo
</Directory>
    


    
    for access to the document /home/web/dir/doc.html
    the steps are:
    

    
      
      
    • Apply directive AllowOverride None
      (disabling .htaccess files).
      • 

      
    • Apply directive AllowOverride FileInfo (for
      directory /home).
      • 

      
    • Apply any FileInfo directives in
      /home/.htaccess, /home/web/.htaccess and
      /home/web/dir/.htaccess in that order.
      • 
    
    

    
    Regular expressions are not considered until after all of the
    normal sections have been applied. Then all of the regular
    expressions are tested in the order they appeared in the
    configuration file. For example, with
    

    
    <Directory ~ "abc$">
  # ... directives here ...
</Directory>
    


    
    the regular expression section won't be considered until after
    all normal <Directory>s and
    .htaccess files have been applied. Then the regular
    expression will match on /home/abc/public_html/abc and
    the corresponding <Directory> will
    be applied.
    

   
    Note that the default access for
    <Directory "/"> is to permit all access.
    This means that Apache httpd will serve any file mapped from an URL. It is
    recommended that you change this with a block such
    as
    

    
    <Directory "/">
  Require all denied
</Directory>
    


    
    and then override this for directories you
    want accessible. See the Security Tips page for more
    details.
    

    
    The directory sections occur in the httpd.conf file.
    <Directory> directives
    cannot nest, and cannot appear in a <Limit> or <LimitExcept> section.

    <DirectoryMatch> and
    </DirectoryMatch> are used to enclose a group
    of directives which will apply only to the named directory (and the files within),
    the same as <Directory>.
    However, it takes as an argument a
    regular expression.  For example:
    

    
    <DirectoryMatch "^/www/(.+/)?[0-9]{3}/">
    # ...
</DirectoryMatch>
    


    
    matches directories in /www/ (or any subdirectory thereof)
    that consist of three numbers.
    

   
    Compatibility
    
      Prior to 2.3.9, this directive implicitly applied to sub-directories
      (like <Directory>) and
      could not match the end of line symbol ($).  In 2.3.9 and later,
      only directories that match the expression are affected by the enclosed
      directives.
    
    

    
    Trailing Slash
    
      This directive applies to requests for directories that may or may
      not end in a trailing slash, so expressions that are anchored to the
      end of line ($) must be written with care.
    
    

    
    From 2.4.8 onwards, named groups and backreferences are captured and
    written to the environment with the corresponding name prefixed with
    "MATCH_" and in upper case. This allows elements of paths to be referenced
    from within expressions and modules like
    mod_rewrite. In order to prevent confusion, numbered
    (unnamed) backreferences are ignored. Use named groups instead.
    

    
    <DirectoryMatch "^/var/www/combined/(?<sitename>[^/]+)">
    Require ldap-group cn=%{env:MATCH_SITENAME},ou=combined,o=Example
</DirectoryMatch>

    This directive sets the directory from which httpd
    will serve files. Unless matched by a directive like Alias, the server appends the
    path from the requested URL to the document root to make the
    path to the document. Example:
    

    
    DocumentRoot "/usr/web"
    


    
    then an access to
    http://my.example.com/index.html refers to
    /usr/web/index.html. If the directory-path is
    not absolute then it is assumed to be relative to the ServerRoot.
    

    
    The DocumentRoot should be specified without
    a trailing slash.

    This directive controls whether the httpd may use
    memory-mapping if it needs to read the contents of a file during
    delivery.  By default, when the handling of a request requires
    access to the data within a file -- for example, when delivering a
    server-parsed file using mod_include -- Apache httpd
    memory-maps the file if the OS supports it.
    

    
    This memory-mapping sometimes yields a performance improvement.
    But in some environments, it is better to disable the memory-mapping
    to prevent operational problems:
    

    
      
    
    • On some multiprocessor systems, memory-mapping can reduce the
    performance of the httpd.
      • 
    
    • Deleting or truncating a file while httpd
      has it memory-mapped can cause httpd to
      crash with a segmentation fault.
    
      • 
    
    

    
    For server configurations that are vulnerable to these problems,
    you should disable memory-mapping of delivered files by specifying:
    

    
    EnableMMAP Off
    


    
    For NFS mounted files, this feature may be disabled explicitly for
    the offending files by specifying:
    

    
    <Directory "/path-to-nfs-files">
  EnableMMAP Off
</Directory>

    EnableSendfile Directive
    

    

    Description:Use the kernel sendfile support to deliver files to the client
    

    Syntax:EnableSendfile On|Off
    

    Default:EnableSendfile Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Core
    

    Module:core
    

    Compatibility:Default changed to Off in
version 2.3.9.
    

    
    
    This directive controls whether httpd may use the
    sendfile support from the kernel to transmit file contents to the client.
    By default, when the handling of a request requires no access
    to the data within a file -- for example, when delivering a
    static file -- Apache httpd uses sendfile to deliver the file contents
    without ever reading the file if the OS supports it.
    

    
    This sendfile mechanism avoids separate read and send operations,
    and buffer allocations. But on some platforms or within some
    filesystems, it is better to disable this feature to avoid
    operational problems:
    

    
      
    
    • Some platforms may have broken sendfile support that the build
    system did not detect, especially if the binaries were built on
    another box and moved to such a machine with broken sendfile
    support.
      • 
    
    • On Linux the use of sendfile triggers TCP-checksum
    offloading bugs on certain networking cards when using IPv6.
      • 
    
    • On Linux on Itanium, sendfile may be unable to handle
    files over 2GB in size.
      • 
    
    • With a network-mounted DocumentRoot (e.g., NFS, SMB, CIFS, FUSE),
    the kernel may be unable to serve the network file through
    its own cache.
      • 
    
    

    
    For server configurations that are not vulnerable to these problems,
    you may enable this feature by specifying:
    

    
    EnableSendfile On
    


    
    For network mounted files, this feature may be disabled explicitly
    for the offending files by specifying:
    

    
    <Directory "/path-to-nfs-files">
  EnableSendfile Off
</Directory>
    

    
    Please note that the per-directory and .htaccess configuration
       of EnableSendfile is not supported by
       mod_cache_disk.
       Only global definition of EnableSendfile
       is taken into account by the module.

    If an error can be detected within the configuration, this
    directive can be used to generate a custom error message, and halt
    configuration parsing.  The typical use is for reporting required
    modules which are missing from the configuration.
    

    
    # Example
# ensure that mod_include is loaded
<IfModule !include_module>
  Error "mod_include is required by mod_foo.  Load it with LoadModule."
</IfModule>

# ensure that exactly one of SSL,NOSSL is defined
<IfDefine SSL>
<IfDefine NOSSL>
  Error "Both SSL and NOSSL are defined.  Define only one of them."
</IfDefine>
</IfDefine>
<IfDefine !SSL>
<IfDefine !NOSSL>
  Error "Either SSL or NOSSL must be defined."

    ErrorDocument Directive
    

    

    Description:What the server will return to the client
in case of an error
    

    Syntax:ErrorDocument error-code document
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Core
    

    Module:core
    

    
    
    In the event of a problem or error, Apache httpd can be configured
    to do one of four things,
    

    
      
      
    1. output a simple hardcoded error message
      2. 

      
    2. output a customized message
      3. 

      
    3. internally redirect to a local URL-path to handle the
      problem/error
      4. 

      
    4. redirect to an external URL to handle the
      problem/error
      5. 
    
    

    
    The first option is the default, while options 2-4 are
    configured using the ErrorDocument
    directive, which is followed by the HTTP response code and a URL
    or a message. Apache httpd will sometimes offer additional information
    regarding the problem/error.
    

    
    From 2.4.13, expression syntax can be
    used inside the directive to produce dynamic strings and URLs.
    

    
    URLs can begin with a slash (/) for local web-paths (relative
    to the DocumentRoot), or be a
    full URL which the client can resolve. Alternatively, a message
    can be provided to be displayed by the browser. Note that deciding
    whether the parameter is an URL, a path or a message is performed
    before any expression is parsed. Examples:
    

    
    ErrorDocument 500 http://example.com/cgi-bin/server-error.cgi
ErrorDocument 404 /errors/bad_urls.php
ErrorDocument 401 /subscription_info.html
ErrorDocument 403 "Sorry, can't allow you access today"
ErrorDocument 403 Forbidden!
ErrorDocument 403 /errors/forbidden.py?referrer=%{escape:%{HTTP_REFERER}}
    


    
    Additionally, the special value default can be used
    to specify Apache httpd's simple hardcoded message.  While not required
    under normal circumstances, default will restore
    Apache httpd's simple hardcoded message for configurations that would
    otherwise inherit an existing ErrorDocument.
    

    
    ErrorDocument 404 /cgi-bin/bad_urls.pl

<Directory "/web/docs">
  ErrorDocument 404 default
</Directory>
    


    
    Note that when you specify an ErrorDocument
    that points to a remote URL (ie. anything with a method such as
    http in front of it), Apache HTTP Server will send a redirect to the
    client to tell it where to find the document, even if the
    document ends up being on the same server. This has several
    implications, the most important being that the client will not
    receive the original error status code, but instead will
    receive a redirect status code. This in turn can confuse web
    robots and other clients which try to determine if a URL is
    valid using the status code. In addition, if you use a remote
    URL in an ErrorDocument 401, the client will not
    know to prompt the user for a password since it will not
    receive the 401 status code. Therefore, if you use an
    ErrorDocument 401 directive, then it must refer to a local
    document.
    

    
    Microsoft Internet Explorer (MSIE) will by default ignore
    server-generated error messages when they are "too small" and substitute
    its own "friendly" error messages. The size threshold varies depending on
    the type of error, but in general, if you make your error document
    greater than 512 bytes, then MSIE will show the server-generated
    error rather than masking it.  More information is available in
    Microsoft Knowledge Base article Q294807.
    

    
    Although most error messages can be overridden, there are certain
    circumstances where the internal messages are used regardless of the
    setting of ErrorDocument.  In
    particular, if a malformed request is detected, normal request processing
    will be immediately halted and the internal error message returned.
    This is necessary to guard against security problems caused by
    bad requests.
    

    
    If you are using mod_proxy, you may wish to enable
    ProxyErrorOverride so that you can provide
    custom error messages on behalf of your Origin servers. If you don't enable ProxyErrorOverride,
    Apache httpd will not generate custom error documents for proxied content.

    ErrorLog Directive
    

    

    Description:Location where the server will log errors
    

    Syntax: ErrorLog file-path|syslog[:[facility][:tag]]
    

    Default:ErrorLog logs/error_log (Unix) ErrorLog logs/error.log (Windows and OS/2)
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The ErrorLog directive sets the name of
    the file to which the server will log any errors it encounters. If
    the file-path is not absolute then it is assumed to be
    relative to the ServerRoot.
    

    
    ErrorLog "/var/log/httpd/error_log"
    


    
    If the file-path
    begins with a pipe character "|" then it is assumed to be a
    command to spawn to handle the error log.
    

    
    ErrorLog "|/usr/local/bin/httpd_errors"
    


    
    See the notes on piped logs for
    more information.
    

    
    Using syslog instead of a filename enables logging
    via syslogd(8) if the system supports it. The default is to use
    syslog facility local7, but you can override this by
    using the syslog:facility syntax where
    facility can be one of the names usually documented in
    syslog(1).  The facility is effectively global, and if it is changed
    in individual virtual hosts, the final facility specified affects the
    entire server. Same rules apply for the syslog tag, which by default
    uses the Apache binary name, httpd in most cases. You can
    also override this by using the syslog::tag
    syntax.
    

    
    ErrorLog syslog:user
ErrorLog syslog:user:httpd.srv1
ErrorLog syslog::httpd.srv2
    


    
    SECURITY: See the security tips
    document for details on why your security could be compromised
    if the directory where log files are stored is writable by
    anyone other than the user that starts the server.
    
    
    Note
    
      
    When entering a file path on non-Unix platforms, care should be taken
      to make sure that only forward slashes are used even though the platform
      may allow the use of back slashes. In general it is a good idea to always
      use forward slashes throughout the configuration files.

    ErrorLogFormat Directive
    

    

    Description:Format specification for error log entries
    

    Syntax: ErrorLogFormat [connection|request] format
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    ErrorLogFormat allows to specify what
    supplementary information is logged in the error log in addition to the
    actual log message.
    

    
    #Simple example
ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M"
    


    
    Specifying connection or request as first
    parameter allows to specify additional formats, causing additional
    information to be logged when the first message is logged for a specific
    connection or request, respectively. This additional information is only
    logged once per connection/request. If a connection or request is processed
    without causing any log message, the additional information is not logged
    either.
    

    
    It can happen that some format string items do not produce output.  For
    example, the Referer header is only present if the log message is
    associated to a request and the log message happens at a time when the
    Referer header has already been read from the client.  If no output is
    produced, the default behavior is to delete everything from the preceding
    space character to the next space character.  This means the log line is
    implicitly divided into fields on non-whitespace to whitespace transitions.
    If a format string item does not produce output, the whole field is
    omitted.  For example, if the remote address %a in the log
    format [%t] [%l] [%a] %M  is not available, the surrounding
    brackets are not logged either.  Space characters can be escaped with a
    backslash to prevent them from delimiting a field.  The combination '% '
    (percent space) is a zero-width field delimiter that does not produce any
    output.
    

    
    The above behavior can be changed by adding modifiers to the format
    string item. A - (minus) modifier causes a minus to be logged if the
    respective item does not produce any output. In once-per-connection/request
    formats, it is also possible to use the + (plus) modifier. If an
    item with the plus modifier does not produce any output, the whole line is
    omitted.
    

    
    A number as modifier can be used to assign a log severity level to a
    format item. The item will only be logged if the severity of the log
    message is not higher than the specified log severity level. The number can
    range from 1 (alert) over 4 (warn) and 7 (debug) to 15 (trace8).
    

    
    For example, here's what would happen if you added modifiers to
    the %{Referer}i token, which logs the
    Referer request header.
    

    
    Modified TokenMeaning
    

    
    %-{Referer}i
    Logs a - if Referer is not set.
    
    

    
    %+{Referer}i
    Omits the entire line if Referer is not set.
    
    

    
    %4{Referer}i
    Logs the Referer only if the log message severity
    is higher than 4.
    
    

    

    
    Some format string items accept additional parameters in braces.
    

    
    Format String Description

    %  (percent space)
        Field delimiter (no output)
    

    

    
    The log ID format %L produces a unique id for a connection
    or request. This can be used to correlate which log lines belong to the
    same connection or request, which request happens on which connection.
    A %L format string is also available in
    mod_log_config to allow to correlate access log entries
    with error log lines. If mod_unique_id is loaded, its
    unique id will be used as log ID for requests.
    

    
    #Example (default format for threaded MPMs)
ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P:tid %T] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i"
    


    
    This would result in error messages such as:
    

    
    
    [Thu May 12 08:28:57.652118 2011] [core:error] [pid 8777:tid 4326490112] [client ::1:58619] File does not exist: /usr/local/apache2/htdocs/favicon.ico
    
    

    
    Notice that, as discussed above, some fields are omitted
    entirely because they are not defined.
    

    
    #Example (similar to the 2.2.x format)
ErrorLogFormat "[%t] [%l] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i"
    


    
    #Advanced example with request/connection log IDs

    This option tracks additional data per worker about the
    currently executing request and creates a utilization summary.
    You can see these variables during runtime by configuring
    mod_status.  Note that other modules may
    rely on this scoreboard.
    

    
    This setting applies to the entire server and cannot be
    enabled or disabled on a virtualhost-by-virtualhost basis.
    The collection of extended status information can slow down
    the server.  Also note that this setting cannot be changed
    during a graceful restart.
    

    
    
    
    Note that loading mod_status will change
    the default behavior to ExtendedStatus On, while other
    third party modules may do the same.  Such modules rely on
    collecting detailed information about the state of all workers.
    The default is changed by mod_status beginning
    with version 2.3.6. The previous default was always Off.

    Compatibility:The default used to be "INode MTime Size" in 2.3.14 and
earlier.
    

    
    
    
    The FileETag directive configures the file
    attributes that are used to create the ETag (entity
    tag) response header field when the document is based on a static file.
    (The ETag value is used in cache management to save
    network bandwidth.) The
    FileETag directive allows you to choose
    which of these -- if any -- should be used. The recognized keywords are:
    
    

    
    
     
    INode
    
     
    The file's i-node number will be included in the calculation
    
     
    MTime
    
     
    The date and time the file was last modified will be included
    
     
    Size
    
     
    The number of bytes in the file will be included
    
     
    All
    
     
    All available fields will be used. This is equivalent to:
         
    FileETag INode MTime Size
    

    
     
    Digest
    
     
    If a document is file-based, the ETag field will be
       calculated by taking the digest over the file.
    
     
    None
    
     
    If a document is file-based, no ETag field will be
       included in the response
    
    
    

    
    The INode, MTime, Size and
    Digest keywords may be prefixed with either +
    or -, which allow changes to be made to the default setting
    inherited from a broader scope. Any keyword appearing without such a prefix
    immediately and completely cancels the inherited setting.
    

    
    If a directory's configuration includes
    FileETag INode MTime Size, and a
    subdirectory's includes FileETag -INode,
    the setting for that subdirectory (which will be inherited by
    any sub-subdirectories that don't override it) will be equivalent to
    FileETag MTime Size.
    
    
    Server Side Includes
    
    An ETag is not generated for responses parsed by mod_include
    since the response entity can change without a change of the INode, MTime,
    Size or Digest of the static file with embedded SSI directives.

    The <Files> directive
    limits the scope of the enclosed directives by filename. It is comparable
    to the <Directory>
    and <Location>
    directives. It should be matched with a </Files>
    directive. The directives given within this section will be applied to
    any object with a basename (last component of filename) matching the
    specified filename. <Files>
    sections are processed in the order they appear in the
    configuration file, after the <Directory> sections and
    .htaccess files are read, but before <Location> sections. Note
    that <Files> can be nested
    inside <Directory> sections to restrict the
    portion of the filesystem they apply to.
    

    
    The filename argument should include a filename, or
    a wild-card string, where ? matches any single character,
    and * matches any sequences of characters.
    
    
    <Files "cat.html">
    # Insert stuff that applies to cat.html here
</Files>

<Files "?at.*">
    # This would apply to cat.html, bat.html, hat.php and so on.
</Files>
    

    
    Regular expressions
    can also be used, with the addition of the
    ~ character. For example:
    

    
    <Files ~ "\.(gif|jpe?g|png)$">
    #...
</Files>
    


    
    would match most common Internet graphics formats. <FilesMatch> is preferred,
    however.
    

    
    Note that unlike <Directory> and <Location> sections, <Files> sections can be used inside
    .htaccess files. This allows users to control access to
    their own files, at a file-by-file level.

    <FilesMatch> Directive

    The <FilesMatch> directive
    limits the scope of the enclosed directives by filename, just as the
    <Files> directive
    does. However, it accepts a regular
    expression. For example:
    

    
    <FilesMatch ".+\.(gif|jpe?g|png)$">
    # ...
</FilesMatch>
    


    
    would match most common Internet graphics formats.
    

    
    The .+ at the start of the regex ensures that
    files named .png, or .gif, for example,
    are not matched.
    

    
    From 2.4.8 onwards, named groups and backreferences are captured and
    written to the environment with the corresponding name prefixed with
    "MATCH_" and in upper case. This allows elements of files to be referenced
    from within expressions and modules like
    mod_rewrite. In order to prevent confusion, numbered
    (unnamed) backreferences are ignored. Use named groups instead.
    

    
    <FilesMatch "^(?<sitename>[^/]+)">
    Require ldap-group cn=%{env:MATCH_SITENAME},ou=combined,o=Example

    This directive allows to configure the maximum number of pipelined
    responses, which remain pending so long as pipelined request are received.
    When the limit is reached, reponses are forcibly flushed to the network in
    blocking mode, until passing under the limit again.
    

    
    FlushMaxPipelined helps constraining memory
    usage. When set to 0 pipelining is disabled, when set to
    -1 there is no limit (FlushMaxThreshold
    still applies).

    This directive allows to configure the threshold for pending output
    data (in bytes). When the limit is reached, data are forcibly flushed to
    the network in blocking mode, until passing under the limit again.
    

    
    FlushMaxThreshold helps constraining memory
    usage. When set to 0 or a too small value there are actually
    no pending data, but for threaded MPMs there can be more threads busy
    waiting for the network thus less ones available to handle the other
    simultaneous connections.

    ForceType Directive

    Context:directory, .htaccess
    

    Override:FileInfo
    

    Status:Core
    

    Module:core
    

    
    
    When placed into an .htaccess file or a
    <Directory>, or
    <Location> or
    <Files>
    section, this directive forces all matching files to be served
    with the content type identification given by
    media-type. For example, if you had a directory full of
    GIF files, but did not want to label them all with .gif,
    you might want to use:
    

    
    ForceType image/gif
    


    
    Note that this directive overrides other indirect media type
    associations defined in mime.types or via the
    AddType.
    

    
    You can also override more general
    ForceType settings
    by using the value of None:
    

    
    # force all files to be image/gif:
<Location "/images">
  ForceType image/gif
</Location>

# but normal mime-type associations here:
<Location "/images/mixed">
  ForceType None
</Location>
    


    
    This directive primarily overrides the content types generated for
    static files served out of the filesystem.  For resources other than
    static files, where the generator of the response typically specifies
    a Content-Type, this directive has no effect.
    

    
    Note
    
    
    When explicit directives such as
    SetHandler or
    AddHandler do not apply
    to the current request, the internal handler name normally set by those
    directives is set to match the content type specified by this directive.
    This is a historical behavior that some third-party modules
    (such as mod_php) may use "magic" content types used only to signal the
    module to take responsibility for the matching request.  Configurations
    that rely on such "magic" types should be avoided by the use of
    SetHandler or
    AddHandler.

    When the server has been compiled with gprof profiling support,
    GprofDir causes gmon.out files to
    be written to the specified directory when the process exits.  If the
    argument ends with a percent symbol ('%'), subdirectories are created
    for each process id.
    

    
    This directive currently only works with the prefork
    MPM.

    HostnameLookups Directive
    

    

    Description:Enables DNS lookups on client IP addresses
    

    Syntax:HostnameLookups On|Off|Double
    

    Default:HostnameLookups Off
    

    Context:server config, virtual host, directory
    

    Status:Core
    

    Module:core
    

    
    
    This directive enables DNS lookups so that host names can be
    logged (and passed to CGIs/SSIs in REMOTE_HOST).
    The value Double refers to doing double-reverse
    DNS lookup. That is, after a reverse lookup is performed, a forward
    lookup is then performed on that result. At least one of the IP
    addresses in the forward lookup must match the original
    address. (In "tcpwrappers" terminology this is called
    PARANOID.)
    

    
    Regardless of the setting, when mod_authz_host is
    used for controlling access by hostname, a double reverse lookup
    will be performed.  This is necessary for security. Note that the
    result of this double-reverse isn't generally available unless you
    set HostnameLookups Double. For example, if only
    HostnameLookups On and a request is made to an object
    that is protected by hostname restrictions, regardless of whether
    the double-reverse fails or not, CGIs will still be passed the
    single-reverse result in REMOTE_HOST.
    

    
    The default is Off in order to save the network
    traffic for those sites that don't truly need the reverse
    lookups done. It is also better for the end users because they
    don't have to suffer the extra latency that a lookup entails.
    Heavily loaded sites should leave this directive
    Off, since DNS lookups can take considerable
    amounts of time. The utility logresolve, compiled by
    default to the bin subdirectory of your installation
    directory, can be used to look up host names from logged IP addresses
    offline.
    

    
    Finally, if you have hostname-based Require
    directives, a hostname lookup will be performed regardless of
    the setting of HostnameLookups.

    HttpProtocolOptions Directive
    

    

    Description:Modify restrictions on HTTP Request Messages
    

    Syntax:HttpProtocolOptions [Strict|Unsafe] [RegisteredMethods|LenientMethods]
 [Allow0.9|Require1.0]
    

    Default:HttpProtocolOptions Strict LenientMethods Allow0.9
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    Compatibility:2.2.32 or 2.4.24 and later
    

    
    
    This directive changes the rules applied to the HTTP Request Line
    (RFC 7230 §3.1.1) and the HTTP Request Header Fields
    (RFC 7230 §3.2), which are now applied by default or using
    the Strict option. Due to legacy modules, applications or
    custom user-agents which must be deprecated the Unsafe
    option has been added to revert to the legacy behaviors.
    

    
    These rules are applied prior to request processing,
    so must be configured at the global or default (first) matching
    virtual host section, by IP/port interface (and not by name)
    to be honored.
    

    
    The directive accepts three parameters from the following list
       of choices, applying the default to the ones not specified:
    

    
    
    
    Strict|Unsafe
    
    
    
      
    Prior to the introduction of this directive, the Apache HTTP Server
      request message parsers were tolerant of a number of forms of input
      which did not conform to the protocol.
      RFC 7230 §9.4 Request Splitting and
      §9.5 Response Smuggling call out only two of the potential
      risks of accepting non-conformant request messages, while
      RFC 7230 §3.5 "Message Parsing Robustness" identify the
      risks of accepting obscure whitespace and request message formatting. 
      As of the introduction of this directive, all grammar rules of the
      specification are enforced in the default Strict operating
      mode, and the strict whitespace suggested by section 3.5 is enforced
      and cannot be relaxed.
    

      
    Security risks of Unsafe
    
        
    Users are strongly cautioned against toggling the Unsafe
        mode of operation, particularly on outward-facing, publicly accessible
        server deployments.  If an interface is required for faulty monitoring
        or other custom service consumers running on an intranet, users should
        toggle the Unsafe option only on a specific virtual host configured
        to service their internal private network.
    
      
    

      
    Example of a request leading to HTTP 400 with Strict mode
    
        
        # Missing CRLF
    
        GET / HTTP/1.0\n\n
      
    
      
    Command line tools and CRLF
    
        
    Some tools need to be forced to use CRLF, otherwise httpd will return
        a HTTP 400 response like described in the above use case. For example,
        the OpenSSL s_client needs the -crlf parameter to work
        properly.
    
        
    The DumpIOInput directive
        can help while reviewing the HTTP request to identify issues like the
        absence of CRLF.
    
      
    
    
    
    
    RegisteredMethods|LenientMethods
    
    
    
      
    RFC 7231 §4.1 "Request Methods" "Overview" requires that
      origin servers shall respond with a HTTP 501 status code when an
      unsupported method is encountered in the request line.
      This already happens when the LenientMethods option is used,
      but administrators may wish to toggle the RegisteredMethods
      option and register any non-standard methods using the
      RegisterHttpMethod
      directive, particularly if the Unsafe
      option has been toggled.
    

      
    Forward Proxy compatibility
    
        
    The RegisteredMethods option should not
        be toggled for forward proxy hosts, as the methods supported by the
        origin servers are unknown to the proxy server.
    
      
    

      
    Example of a request leading to HTTP 501 with LenientMethods mode
    
        
        # Unknown HTTP method
    
        WOW / HTTP/1.0\r\n\r\n

    
        # Lowercase HTTP method
    
        get / HTTP/1.0\r\n\r\n
    
      
    
      
    
      
    Allow0.9|Require1.0
    
      
    
      
    RFC 2616 §19.6 "Compatibility With Previous Versions" had
      encouraged HTTP servers to support legacy HTTP/0.9 requests. RFC 7230
      supersedes this with "The expectation to support HTTP/0.9 requests has
      been removed" and offers additional comments in 
      RFC 7230 Appendix A. The Require1.0 option allows
      the user to remove support of the default Allow0.9 option's
      behavior.
    

      
    Example of a request leading to HTTP 400 with Require1.0 mode
    
        
        # Unsupported HTTP version
    
        GET /\r\n\r\n
      
    
    
    
    
    
    
    Reviewing the messages logged to the
    ErrorLog, configured with
    LogLevel debug level,
    can help identify such faulty requests along with their origin.
    Users should pay particular attention to the 400 responses in the access
    log for invalid requests which were unexpectedly rejected.

    For example:
    

    
    <If "-z req('Host')">
    


    
    would match HTTP/1.0 requests without a Host: header.
    Expressions may contain various shell-like operators for string
    comparison (==, !=, <, ...),
    integer comparison (-eq, -ne, ...),
    and others (-n, -z, -f, ...).
    It is also possible to use regular expressions, 
    

    
    <If "%{QUERY_STRING} =~ /(delete|commit)=.*?elem/">
    


    
    shell-like pattern matches and many other operations. These operations
    can be done on request headers (req), environment variables
    (env), and a large number of other properties. The full
    documentation is available in Expressions in
    Apache HTTP Server.
    

    
    Only directives that support the directory context can be used within this configuration section.
    

    
    
    Certain variables, such as CONTENT_TYPE and other
    response headers, are set after <If> conditions have already
    been evaluated, and so will not be available to use in this
    directive.

    section are only processed if the test is true. If 
    test is false, everything between the start and end markers is
    ignored.
    

    
    The test in the <IfDefine> section directive can be one of two forms:
    

    
      
      
    • parameter-name
      • 

      
    • !parameter-name
      • 
    
    

    
    In the former case, the directives between the start and end
    markers are only processed if the parameter named
    parameter-name is defined. The second format reverses
    the test, and only processes the directives if
    parameter-name is not defined.
    

    
    The parameter-name argument is a define as given on the
    httpd command line via -Dparameter
     at the time the server was started or by the Define directive.
    

    
    <IfDefine> sections are
    nest-able, which can be used to implement simple
    multiple-parameter tests. Example:

    This section should only be used if you need to have one

    doesn't exist, everything between the start and end markers is
    ignored. filename can be an absolute path or a path
    relative to the server root.
    

    
    The filename in the <IfFile> section directive can take the same forms as the
    test variable in the <IfDefine> section, i.e. the test can be negated if the 
    ! character is placed directly before filename.
    
    
   
    
    If a relative filename is supplied, the check is
    ServerRoot relative. In the case where
    this directive occurs before the ServerRoot,
    the path will be checked relative to the compiled-in server root or
    the server root passed in on the command line via the -d
    parameter.

    In the former case, the directives between the start and end
    markers are only processed if the module named module
    is included in Apache httpd -- either compiled in or
    dynamically loaded using LoadModule. The second format reverses the test,
    and only processes the directives if module is
    not included.
    

    
    The module argument can be either the module identifier or
    the file name of the module, at the time it was compiled.  For example,
    rewrite_module is the identifier and
    mod_rewrite.c is the file name. If a module consists of
    several source files, use the name of the file containing the string
    STANDARD20_MODULE_STUFF.
    

    
    <IfModule> sections are
    nest-able, which can be used to implement simple multiple-module
    tests.
    

    
    This section should only be used if you need to have one
    configuration file that works whether or not a specific module
    is available. In normal operation, directives need not be
    placed in <IfModule>
    sections.

    <IfSection> Directive
    

    

    Description:Encloses directives that are processed conditional on the
presence or absence of a specific section directive

    The <IfSection
    test>...</IfSection> section is used
    to mark directives that are conditional on the presence of a
    specific section directive.  A section directive is any directive
    such as <VirtualHost> which
    encloses other directives, and has a directive name with a leading
    "<".
    

    
    The directives within an <IfSection> section are only processed if the test
    is true. If test is false, everything between the start and
    end markers is ignored.
    

    
    The section-name must be specified without either
    the leading "<" or closing ">".  The test in the
    <IfSection> section can be one
    of two forms:
    

    
      
      
    • section-name
      • 
      
    • !section-name
      • 
    
    

    
    In the former case, the directives between the start and end
    markers are only processed if a section directive of the given
    name is available at the time of processing.  The second format
    reverses the test, and only processes the directives if
    section-name is not an available
    section directive.
    

    
    For example:
    

    
    <IfSection VirtualHost>
   ...
</IfSection>
    

    
    
    This section should only be used if you need to have one
    configuration file that works across multiple versions of httpd,
    regardless of whether a particular section directive is
    available. In normal operation, directives need not be placed in
    <IfSection> sections.

    Include Directive
    

    

    Description:Includes other configuration files from within

wildcard matching available in 2.3.6 and later
    

    
    
    This directive allows inclusion of other configuration files
    from within the server configuration files.
    

    
    Shell-style (fnmatch()) wildcard characters can be used
    in the filename or directory parts of the path to include several files
    at once, in alphabetical order. In addition, if
    Include points to a directory, rather than a file,
    Apache httpd will read all files in that directory and any subdirectory.
    However, including entire directories is not recommended, because it is
    easy to accidentally leave temporary files in a directory that can cause
    httpd to fail. Instead, we encourage you to use the
    wildcard syntax shown below, to include files that match a particular
    pattern, such as *.conf, for example.
    

    
    The Include directive will
    fail with an error if a wildcard expression does not
    match any file. The IncludeOptional
    directive can be used if non-matching wildcards should be ignored.
    

    
    The file path specified may be an absolute path, or may be relative
    to the ServerRoot directory.
    

    
    Examples:
    

    
    Include /usr/local/apache2/conf/ssl.conf
Include /usr/local/apache2/conf/vhosts/*.conf
    


    
    Or, providing paths relative to your ServerRoot directory:
    

    
    Include conf/ssl.conf
Include conf/vhosts/*.conf
    


    
    Wildcards may be included in the directory or file portion of the
    path. This example will fail if there is no subdirectory in conf/vhosts
    that contains at least one *.conf file:
    

    
    Include conf/vhosts/*/*.conf
    


    
    Alternatively, the following command will just be ignored in case of
    missing files or directories:
    

    
    IncludeOptional conf/vhosts/*/*.conf

    This directive allows inclusion of other configuration files
    from within the server configuration files. It works identically to the
    Include directive, but it will be
    silently ignored (instead of causing an error) if wildcards are used and
    they do not match any file or directory or if a file path does not exist
    on the file system.

    KeepAlive Directive
    

    

    Description:Enables HTTP persistent connections
    

    Syntax:KeepAlive On|Off
    

    Default:KeepAlive On
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The Keep-Alive extension to HTTP/1.0 and the persistent
    connection feature of HTTP/1.1 provide long-lived HTTP sessions
    which allow multiple requests to be sent over the same TCP
    connection. In some cases this has been shown to result in an
    almost 50% speedup in latency times for HTML documents with
    many images. To enable Keep-Alive connections, set
    KeepAlive On.
    

    
    For HTTP/1.0 clients, Keep-Alive connections will only be
    used if they are specifically requested by a client. In
    addition, a Keep-Alive connection with an HTTP/1.0 client can
    only be used when the length of the content is known in
    advance. This implies that dynamic content such as CGI output,
    SSI pages, and server-generated directory listings will
    generally not use Keep-Alive connections to HTTP/1.0 clients.
    For HTTP/1.1 clients, persistent connections are the default
    unless otherwise specified. If the client requests it, chunked
    encoding will be used in order to send content of unknown
    length over persistent connections.
    

    
    When a client uses a Keep-Alive connection, it will be counted
    as a single "request" for the MaxConnectionsPerChild directive, regardless
    of how many requests are sent using the connection.

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The number of seconds Apache httpd will wait for a subsequent
    request before closing the connection. By adding a postfix of ms the
    timeout can be also set in milliseconds. Once a request has been
    received, the timeout value specified by the
    Timeout directive applies.
    

    
    Setting KeepAliveTimeout to a high value
    may cause performance problems in heavily loaded servers. The
    higher the timeout, the more server processes will be kept
    occupied waiting on connections with idle clients.
    

    
    If KeepAliveTimeout is not
    set for a name-based virtual host, the value of the first defined
    virtual host best matching the local IP and port will be used.

    <Limit> Directive
    

    

    Description:Restrict enclosed access controls to only certain HTTP
methods
    

    Syntax:<Limit method [method] ... > ...
    </Limit>
    

    Context:directory, .htaccess
    

    Override:AuthConfig, Limit
    

    Status:Core
    

    Module:core
    

    
    
    Access controls are normally effective for
    all access methods, and this is the usual
    desired behavior. In the general case, access control
    directives should not be placed within a
    <Limit> section.
    

    
    The purpose of the <Limit>
    directive is to restrict the effect of the access controls to the
    nominated HTTP methods. For all other methods, the access
    restrictions that are enclosed in the <Limit> bracket will have no
    effect. The following example applies the access control
    only to the methods POST, PUT, and
    DELETE, leaving all other methods unprotected:
    

    
    <Limit POST PUT DELETE>
  Require valid-user
</Limit>
    


    
    The method names listed can be one or more of: GET,
    POST, PUT, DELETE,
    CONNECT, OPTIONS,
    PATCH, PROPFIND, PROPPATCH,
    MKCOL, COPY, MOVE,
    LOCK, and UNLOCK. The method name is
    case-sensitive. If GET is used, it will also
    restrict HEAD requests. The TRACE method
    cannot be limited (see TraceEnable).
    

    
    A <LimitExcept> section should always be
    used in preference to a <Limit>
    section when restricting access, since a <LimitExcept> section provides protection
    against arbitrary methods.
    

    
    The <Limit> and
    <LimitExcept>
    directives may be nested.  In this case, each successive level of
    <Limit> or <LimitExcept> directives must
    further restrict the set of methods to which access controls apply.
    

    
    When using
    <Limit> or
    <LimitExcept> directives with
    the Require directive,
    note that the first Require
    to succeed authorizes the request, regardless of the presence of other
    Require directives.
    

    
    For example, given the following configuration, all users will
    be authorized for POST requests, and the
    Require group editors directive will be ignored
    in all cases:
    

    
    <LimitExcept GET>
  Require valid-user
</LimitExcept>
<Limit POST>
  Require group editors
</Limit>

    <LimitExcept> and

    a group of access control directives which will then apply to any
    HTTP access method not listed in the arguments;
    i.e., it is the opposite of a <Limit> section and can be used to control
    both standard and nonstandard/unrecognized methods. See the
    documentation for <Limit> for more details.
    

    
    For example:
    

    
    <LimitExcept POST GET>
  Require valid-user
</LimitExcept>

    LimitInternalRecursion Directive
    

    

    Description:Determine maximum number of internal redirects and nested
subrequests
    

    Syntax:LimitInternalRecursion number [number]
    

    Default:LimitInternalRecursion 10
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    An internal redirect happens, for example, when using the Action directive, which internally
    redirects the original request to a CGI script. A subrequest is Apache httpd's
    mechanism to find out what would happen for some URI if it were requested.
    For example, mod_dir uses subrequests to look for the
    files listed in the DirectoryIndex
    directive.
    

    
    LimitInternalRecursion prevents the server
    from crashing when entering an infinite loop of internal redirects or
    subrequests. Such loops are usually caused by misconfigurations.
    

    
    The directive stores two different limits, which are evaluated on
    per-request basis. The first number is the maximum number of
    internal redirects that may follow each other. The second number
    determines how deeply subrequests may be nested. If you specify only one
    number, it will be assigned to both limits.

    LimitRequestBody Directive
    

    

    Description:Restricts the total size of the HTTP request body sent

    Syntax:LimitRequestBody bytes
    

    Default:LimitRequestBody 0
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:All
    

    Status:Core
    

    Module:core
    

    
    
    This directive specifies the number of bytes from 0
    (meaning unlimited) to 2147483647 (2GB) that are allowed in a
    request body. See the note below for the limited applicability
    to proxy requests.
    

    
    The LimitRequestBody directive allows
    the user to set a limit on the allowed size of an HTTP request
    message body within the context in which the directive is given
    (server, per-directory, per-file or per-location). If the client
    request exceeds that limit, the server will return an error
    response instead of servicing the request. The size of a normal
    request message body will vary greatly depending on the nature of
    the resource and the methods allowed on that resource. CGI scripts
    typically use the message body for retrieving form information.
    Implementations of the PUT method will require
    a value at least as large as any representation that the server
    wishes to accept for that resource.
    

    
    This directive gives the server administrator greater
    control over abnormal client request behavior, which may be
    useful for avoiding some forms of denial-of-service
    attacks.
    

    
    If, for example, you are permitting file upload to a particular
    location and wish to limit the size of the uploaded file to 100K,
    you might use the following directive:
    

    
    LimitRequestBody 102400
    


    
    For a full description of how this directive is interpreted by
    proxy requests, see the mod_proxy documentation.

    Setting number at 0 means unlimited.
    The default value is defined by the compile-time
    constant DEFAULT_LIMIT_REQUEST_FIELDS (100 as
    distributed).
    

    
    The LimitRequestFields directive allows
    the server administrator to modify the limit on the number of
    request header fields allowed in an HTTP request. A server needs
    this value to be larger than the number of fields that a normal
    client request might include. The number of request header fields
    used by a client rarely exceeds 20, but this may vary among
    different client implementations, often depending upon the extent
    to which a user has configured their browser to support detailed
    content negotiation. Optional HTTP extensions are often expressed
    using request header fields.
    

    
    This directive gives the server administrator greater
    control over abnormal client request behavior, which may be
    useful for avoiding some forms of denial-of-service attacks.
    The value should be increased if normal clients see an error
    response from the server that indicates too many fields were
    sent in the request.
    

    
    For example:
    

    
    LimitRequestFields 50

    needs this value to be large enough to hold any one header field
    from a normal client request. The size of a normal request header
    field will vary greatly among different client implementations,
    often depending upon the extent to which a user has configured
    their browser to support detailed content negotiation. SPNEGO
    authentication headers can be up to 12392 bytes.

    The LimitRequestLine directive allows
    the server administrator to set the limit on the allowed size
    of a client's HTTP request-line. Since the request-line consists of the
    HTTP method, URI, and protocol version, the
    LimitRequestLine directive places a
    restriction on the length of a request-URI allowed for a request
    on the server. A server needs this value to be large enough to
    hold any of its resource names, including any information that
    might be passed in the query part of a GET request.

    <Location> Directive
    

    

    Description:Applies the enclosed directives only to matching
URLs
    

    Syntax:<Location
    URL-path|URL> ... </Location>
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The <Location> directive
    limits the scope of the enclosed directives by URL. It is similar to the
    <Directory>
    directive, and starts a subsection which is terminated with a
    </Location> directive. <Location> sections are processed in the
    order they appear in the configuration file, after the <Directory> sections and
    .htaccess files are read, and after the <Files> sections.
    

    
    <Location> sections operate
    completely outside the filesystem.  This has several consequences.
    Most importantly, <Location>
    directives should not be used to control access to filesystem
    locations.  Since several different URLs may map to the same
    filesystem location, such access controls may by circumvented.
    

    
    The enclosed directives will be applied to the request if the path component
    of the URL meets any of the following criteria:
    
    
    
      
      
    • The specified location matches exactly the path component of the URL.
      
      • 
      
    • The specified location, which ends in a forward slash, is a prefix
      of the path component of the URL (treated as a context root).
      
      • 
      
    • The specified location, with the addition of a trailing slash, is a
      prefix of the path component of the URL (also treated as a context root).
      
      • 
    
    
    
    
    In the example below, where no trailing slash is used, requests to
    /private1, /private1/ and /private1/file.txt will have the enclosed
    directives applied, but /private1other would not.
    
    
    
    <Location "/private1">
    #  ...
</Location>
    

    
    
    In the example below, where a trailing slash is used, requests to
    /private2/ and /private2/file.txt will have the enclosed
    directives applied, but /private2 and /private2other would not.
    
    
    
    <Location "/private2/">
    # ...
</Location>
    


    
    When to use <Location>
    

    
    Use <Location> to apply
    directives to content that lives outside the filesystem.  For
    content that lives in the filesystem, use <Directory> and <Files>.  An exception is
    <Location "/">, which is an easy way to
    apply a configuration to the entire server.
    
    
    

    
    For all origin (non-proxy) requests, the URL to be matched is a
    URL-path of the form /path/.  No scheme, hostname,
    port, or query string may be included.  For proxy requests, the
    URL to be matched is of the form
    scheme://servername/path, and you must include the
    prefix.
    

    
    The URL may use wildcards. In a wild-card string, ? matches
    any single character, and * matches any sequences of
    characters. Neither wildcard character matches a / in the URL-path.
    

    
    Regular expressions
    can also be used, with the addition of the ~
    character. For example:
    

    
    <Location ~ "/(extra|special)/data">
    #...
</Location>
    


    
    would match URLs that contained the substring /extra/data
    or /special/data. The directive <LocationMatch> behaves
    identical to the regex version of <Location>, and is preferred, for the
    simple reason that ~ is hard to distinguish from
    - in many fonts.
    

    
    The <Location>
    functionality is especially useful when combined with the
    SetHandler
    directive. For example, to enable status requests but allow them
    only from browsers at example.com, you might use:
    

    
    <Location "/status">
  SetHandler server-status
  Require host example.com
</Location>
    


    
    Note about / (slash)
    
      
    The slash character has special meaning depending on where in a
      URL it appears. People may be used to its behavior in the filesystem
      where multiple adjacent slashes are frequently collapsed to a single
      slash (i.e., /home///foo is the same as
      /home/foo). In URL-space this is not necessarily true if
      directive MergeSlashes  has been set
      to "OFF".
      The <LocationMatch>
      directive and the regex version of <Location> require you to explicitly specify multiple
      slashes if the slashes are not being merged.
    

      
    For example, <LocationMatch "^/abc"> would match
      the request URL /abc but not the request URL 
      //abc. The (non-regex) <Location> directive behaves similarly when used for
      proxy requests. But when (non-regex) <Location> is used for non-proxy requests it will
      implicitly match multiple slashes with a single slash. For example,
      if you specify <Location "/abc/def"> and the
      request is to /abc//def then it will match.

    <LocationMatch> Directive
    

    

    Description:Applies the enclosed directives only to regular-expression
matching URLs
    

    Syntax:<LocationMatch
    regex> ... </LocationMatch>
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The <LocationMatch> directive
    limits the scope of the enclosed directives by URL, in an identical manner
    to <Location>. However,
    it takes a regular expression
    as an argument instead of a simple string. For example:
    

    
    <LocationMatch "/(extra|special)/data">
    # ...
</LocationMatch>
    


    
    would match URLs that contained the substring /extra/data
    or /special/data.
    

    
    If the intent is that a URL starts with
    /extra/data, rather than merely
    contains /extra/data, prefix the
    regular expression with a ^ to require this.
    

    
    <LocationMatch "^/(extra|special)/data">
    

    
    

    
    From 2.4.8 onwards, named groups and backreferences are captured and
    written to the environment with the corresponding name prefixed with
    "MATCH_" and in upper case. This allows elements of URLs to be referenced
    from within expressions and modules like
    mod_rewrite. In order to prevent confusion, numbered
    (unnamed) backreferences are ignored. Use named groups instead.
    

    
    <LocationMatch "^/combined/(?<sitename>[^/]+)">
    Require ldap-group cn=%{env:MATCH_SITENAME},ou=combined,o=Example
</LocationMatch>

    LogLevel Directive

    When a particular level is specified, messages from all
    other levels of higher significance will be reported as well.
    E.g., when LogLevel info is specified,
    then messages with log levels of notice and
    warn will also be posted.
    

    
    Using a level of at least crit is
    recommended.
    

    
    For example:
    

    
    LogLevel notice
    


    
    Note
    
      
    When logging to a regular file, messages of the level
      notice cannot be suppressed and thus are always
      logged. However, this doesn't apply when logging is done
      using syslog.
    
    
    

    
    Specifying a level without a module name will reset the level
    for all modules to that level.  Specifying a level with a module
    name will set the level for that module only. It is possible to
    use the module source file name, the module identifier, or the
    module identifier with the trailing _module omitted
    as module specification. This means the following three specifications
    are equivalent:
    

    
    LogLevel info ssl:warn
LogLevel info mod_ssl.c:warn
LogLevel info ssl_module:warn
    


    
    It is also possible to change the level per directory:
    

    
    LogLevel info
<Directory "/usr/local/apache/htdocs/app">
  LogLevel debug
</Directory>
    


    
    
        Per directory loglevel configuration only affects messages that are
        logged after the request has been parsed and that are associated with
        the request. Log messages which are associated with the connection or
        the server are not affected.

    MergeSlashes Directive

    Status:Core
    

    Module:core
    

    Compatibility:Added in 2.4.39
    

    
    
    By default, the server merges (or collapses) multiple consecutive slash
    ('/') characters in the path component of the request URL.
    

    
    When mapping URL's to the filesystem, these multiple slashes are not 
    significant.  However, URL's handled other ways, such as by CGI or proxy,
    might prefer to retain the significance of multiple consecutive slashes. 
    In these cases MergeSlashes can be set to 
    OFF to retain the multiple consecutive slashes, which is the legacy behavior.
    
    
    
    When set to "OFF", regular expressions used in the configuration file that match
    the path component of the URL (LocationMatch,
    RewriteRule, ...) need to take into account multiple 
    consecutive slashes. Non regular expression based Location always
    operate against a URL with merged slashes and cannot differentiate between multiple slashes.

    Default:Mutex default
    

    Context:server config
    

    Status:Core
    

    Module:core
    

    Compatibility:Available in Apache HTTP Server 2.3.4 and later
    

    
    
    The Mutex directive sets the mechanism,
    and optionally the lock file location, that httpd and modules use
    to serialize access to resources.  Specify default as
    the second argument to change the settings for all mutexes; specify
    a mutex name (see table below) as the second argument to override
    defaults only for that mutex.
    

    
    The Mutex directive is typically used in
    the following exceptional situations:
    

    
      
        
    • change the mutex mechanism when the default mechanism selected
        by APR has a functional or performance
        problem
      • 

        
    • change the directory used by file-based mutexes when the
        default directory does not support locking
      • 
    
    

    
    Supported modules
    
    
    This directive only configures mutexes which have been registered
    with the core server using the ap_mutex_register() API.
    All modules bundled with httpd support the Mutex
    directive, but third-party modules may not.  Consult the documentation
    of the third-party module, which must indicate the mutex name(s) which
    can be configured if this directive is supported.
    
    
    

    
    The following mutex mechanisms are available:
    
    
      
        
    • default | yes
        
      This selects the default locking implementation, as determined by
        APR.  The default locking implementation can
        be displayed by running httpd with the
        -V option.
      • 

        
    • none | no
        
      This effectively disables the mutex, and is only allowed for a
        mutex if the module indicates that it is a valid choice.  Consult the
        module documentation for more information.
      • 

        
    • posixsem
        
      This is a mutex variant based on a Posix semaphore.
      

        
      Warning
      
        
      The semaphore ownership is not recovered if a thread in the process
        holding the mutex segfaults, resulting in a hang of the web server.
      
        
      
        
      • 

        
    • sysvsem
        
      This is a mutex variant based on a SystemV IPC semaphore.
      

        
      Warning
      
        
      It is possible to "leak" SysV semaphores if processes crash
        before the semaphore is removed.
      
	
      

        
      Security
      
        
      The semaphore API allows for a denial of service attack by any
        CGIs running under the same uid as the webserver (i.e.,
        all CGIs, unless you use something like suexec
        or cgiwrapper).
      
	
      
        
      • 

        
    • sem
        
      This selects the "best" available semaphore implementation, choosing
        between Posix and SystemV IPC semaphores, in that order.
      • 

        
    • pthread
        
      This is a mutex variant based on cross-process Posix thread
        mutexes.
      

        
      Warning
      
        
      On most systems, if a child process terminates abnormally while
        holding a mutex that uses this implementation, the server will deadlock
        and stop responding to requests.  When this occurs, the server will
        require a manual restart to recover.
      
        
      Solaris and Linux are notable exceptions as they provide a mechanism which
        usually allows the mutex to be recovered after a child process
        terminates abnormally while holding a mutex.
      
        
      If your system is POSIX compliant or if it implements the
        pthread_mutexattr_setrobust_np() function, you may be able
        to use the pthread option safely.
      
        
      
        
      • 

        
    • fcntl:/path/to/mutex
        
      This is a mutex variant where a physical (lock-)file and the
        fcntl() function are used as the mutex.
      

        
      Warning
      
        
      When multiple mutexes based on this mechanism are used within
        multi-threaded, multi-process environments, deadlock errors (EDEADLK)
        can be reported for valid mutex operations if fcntl()
        is not thread-aware, such as on Solaris.
      
	
      
        
      • 

        
    • flock:/path/to/mutex
        
      This is similar to the fcntl:/path/to/mutex method
        with the exception that the flock() function is used to
        provide file locking.
      • 

        
    • file:/path/to/mutex
        
      This selects the "best" available file locking implementation,
        choosing between fcntl and flock, in that
        order.
      • 
    
    

    
    Most mechanisms are only available on selected platforms, where the
    underlying platform and APR support it.  Mechanisms
    which aren't available on all platforms are posixsem,
    sysvsem, sem, pthread, fcntl,
    flock, and file.
    

    
    With the file-based mechanisms fcntl and flock,
    the path, if provided, is a directory where the lock file will be created.
    The default directory is httpd's run-time file directory relative to
    ServerRoot.  Always use a local disk
    filesystem for /path/to/mutex and never a directory residing
    on a NFS- or AFS-filesystem.  The basename of the file will be the mutex
    type, an optional instance string provided by the module, and unless the
    OmitPID keyword is specified, the process id of the httpd
    parent process will be appended to make the file name unique, avoiding
    conflicts when multiple httpd instances share a lock file directory.  For
    example, if the mutex name is mpm-accept and the lock file
    directory is /var/httpd/locks, the lock file name for the
    httpd instance with parent process id 12345 would be
    /var/httpd/locks/mpm-accept.12345.
    

    
    Security
    
    
    It is best to avoid putting mutex files in a world-writable
    directory such as /var/tmp because someone could create
    a denial of service attack and prevent the server from starting by
    creating a lockfile with the same name as the one the server will try
    to create.
    
    
    

    
    The following table documents the names of mutexes used by httpd
    and bundled modules.

    The OmitPID keyword suppresses the addition of the httpd
    parent process id from the lock file name.
    

    
    In the following example, the mutex mechanism for the MPM accept
    mutex will be changed from the compiled-in default to fcntl,
    with the associated lock file created in directory
    /var/httpd/locks.  The mutex mechanism for all other mutexes
    will be changed from the compiled-in default to sysvsem.

    Options Directive
    

    

    Description:Configures what features are available in a particular
directory
    

    Syntax:Options

    Default:Options FollowSymlinks
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Core
    

    Module:core
    

    Compatibility:The default was changed from All to FollowSymlinks in 2.3.11
    

    
    
    The Options directive controls which
    server features are available in a particular directory.
    

    
    option can be set to None, in which
    case none of the extra features are enabled, or one or more of
    the following:
    

    
    
      
    All
    

      
    All options except for MultiViews.
    

      
    ExecCGI
    

      
    
      Execution of CGI scripts using mod_cgi
      is permitted.
    

      
    FollowSymLinks
    

      
    
      The server will follow symbolic links in this directory. This is
      the default setting.
      
    
      
    Even though the server follows the symlink it does not
      change the pathname used to match against <Directory> sections.
    

      
    The FollowSymLinks and
      SymLinksIfOwnerMatch Options work only in <Directory> sections or
      .htaccess files.
    

      
    Omitting this option should not be considered a security restriction,
      since symlink testing is subject to race conditions that make it
      circumventable.
    
      
    

      
    Includes
    

      
    
      Server-side includes provided by mod_include
      are permitted.
    

      
    IncludesNOEXEC
    

      
    

      Server-side includes are permitted, but the #exec
      cmd and #exec cgi are disabled. It is still
      possible to #include virtual CGI scripts from
      ScriptAliased
      directories.
    

      
    Indexes
    

      
    
      If a URL which maps to a directory is requested and there
      is no DirectoryIndex
      (e.g., index.html) in that directory, then
      mod_autoindex will return a formatted listing
      of the directory.
    

      
    MultiViews
    

      
    
      Content negotiated
      "MultiViews" are allowed using
      mod_negotiation.
      
    Note
     
    This option gets ignored if set
      anywhere other than <Directory>, as mod_negotiation
      needs real resources to compare against and evaluate from.
    
      
    

      
    SymLinksIfOwnerMatch
    

      
    The server will only follow symbolic links for which the
      target file or directory is owned by the same user id as the
      link.

      
    Note
    
      
    The FollowSymLinks and
      SymLinksIfOwnerMatch Options work only in <Directory> sections or
      .htaccess files.
    

      
    This option should not be considered a security restriction,
      since symlink testing is subject to race conditions that make it
      circumventable.
    
      
     
    
    
    

    
    Normally, if multiple Options could
    apply to a directory, then the most specific one is used and
    others are ignored; the options are not merged. (See how sections are merged.)
    However if all the options on the
    Options directive are preceded by a
    + or - symbol, the options are
    merged. Any options preceded by a + are added to the
    options currently in force, and any options preceded by a
    - are removed from the options currently in
    force. 
    

    
    Note
    
    
    Mixing Options with a + or
    - with those without is not valid syntax and will be
    rejected during server startup by the syntax check with an abort.
    
    
    

    
    For example, without any + and - symbols:
    

    
    <Directory "/web/docs">
  Options Indexes FollowSymLinks
</Directory>

<Directory "/web/docs/spec">
  Options Includes
</Directory>
    


    
    then only Includes will be set for the
    /web/docs/spec directory. However if the second
    Options directive uses the + and
    - symbols:
    

    
    <Directory "/web/docs">
  Options Indexes FollowSymLinks
</Directory>

<Directory "/web/docs/spec">
  Options +Includes -Indexes
</Directory>
    


    
    then the options FollowSymLinks and
    Includes are set for the /web/docs/spec
    directory.
    

    
    Note
    
      
    Using -IncludesNOEXEC or
      -Includes disables server-side includes completely
      regardless of the previous setting.
    
    
    

    
    The default in the absence of any other settings is
    FollowSymlinks.

    Protocol Directive
    

    

    Description:Protocol for a listening socket
    

    Syntax:Protocol protocol
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    Compatibility:Available in Apache 2.1.5 and later.
On Windows, from Apache 2.3.3 and later.
    

    
    
    This directive specifies the protocol used for a specific listening socket.
       The protocol is used to determine which module should handle a request and
       to apply protocol specific optimizations with the AcceptFilter
       directive.
    
 
    
    This directive not required for most
       configurations. If not specified, https is the default for
       port 443 and http the default for all other ports.  The
       protocol is used to determine which module should handle a request, and
       to apply protocol specific optimizations with the
       AcceptFilter directive.
    

    
    For example, if you are running https on a non-standard port,
       specify the protocol explicitly:
    

    
    Protocol https
    


    
    You can also specify the protocol using the Listen directive.

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    Compatibility:Only available from Apache 2.4.17 and later.
    

    
        
    This directive specifies the list of protocols supported for a
            server/virtual host. The list determines the allowed protocols
            a client may negotiate for this server/host.
    
        
        
    You need to set protocols if you want to extend the available
            protocols for a server/host. By default, only the http/1.1 protocol
            (which includes the compatibility with 1.0 and 0.9 clients) is
            allowed.
    
        
        
    For example, if you want to support HTTP/2 for a server with TLS, 
            specify:
    
        
        
    Protocols h2 http/1.1
    


        
    Valid protocols are http/1.1 for http and https connections,
            h2 on https connections and h2c for http
            connections. Modules may enable more protocols.
    
        
        
    It is safe to specify protocols that are unavailable/disabled. Such
        protocol names will simply be ignored.
    
        
        
    Protocols specified in base servers are inherited for virtual hosts 
            only if the virtual host has no own Protocols directive. Or, the other
            way around, Protocols directives in virtual hosts replace any
            such directive in the base server.

    This directive specifies if the server should honor the order in which
        the Protocols directive lists protocols.
    
        
        
    If configured Off, the client supplied list order of protocols has 
            precedence over the order in the server configuration.
    
        
        
    With ProtocolsHonorOrder set to on 
            (default), the client ordering does not matter and only the ordering 
            in the server settings influences the outcome of the protocol 
            negotiation.

    This directive controls whether the server will ensure that the 
    REDIRECT_URL environment variable is fully qualified.  By default, 
    the variable contains the verbatim URL requested by the client, 
    such as "/index.html".  With QualifyRedirectURL On, the same request would result in a
    value such as "http://www.example.com/index.html".
    
    
    Even without this directive set, when a request is issued against a 
    fully qualified URL, REDIRECT_URL will remain fully qualified.

    Takes 1 or 2 parameters. The first parameter sets the soft
    resource limit for all processes, and the second parameter sets
    the maximum resource limit. Either parameter can be a number,
    or max to indicate to the server that the limit
    should be set to the maximum allowed by the operating system
    configuration. Raising the maximum resource limit requires that
    the server is running as root or in the initial startup
    phase.
    

    
    This applies to processes forked from Apache httpd children
    servicing requests, not the Apache httpd children themselves. This
    includes CGI scripts and SSI exec commands, but not any
    processes forked from the Apache httpd parent, such as piped
    logs.
    

    
    Process limits control the number of processes per user.
    

    
    Note
    
      
    If CGI processes are not running
      under user ids other than the web server user id, this directive
      will limit the number of processes that the server itself can
      create. Evidence of this situation will be indicated by
      cannot fork messages in the
      error_log.

    ScriptInterpreterSource Directive
    

    

    Description:Technique for locating the interpreter for CGI
scripts
    

    Syntax:ScriptInterpreterSource Registry|Registry-Strict|Script
    

    Default:ScriptInterpreterSource Script
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Core
    

    Module:core
    

    Compatibility:Win32 only.
    

    
    
    This directive is used to control how Apache httpd finds the
    interpreter used to run CGI scripts. The default setting is
    Script. This causes Apache httpd to use the interpreter pointed to
    by the shebang line (first line, starting with #!) in the
    script. On Win32 systems this line usually looks like:
    

    
    #!C:/Perl/bin/perl.exe
    


    
    or, if perl is in the PATH, simply:
    

    
    #!perl
    


    
    Setting ScriptInterpreterSource Registry will
    cause the Windows Registry tree HKEY_CLASSES_ROOT to be
    searched using the script file extension (e.g., .pl) as a
    search key. The command defined by the registry subkey
    Shell\ExecCGI\Command or, if it does not exist, by the subkey
    Shell\Open\Command is used to open the script file. If the
    registry keys cannot be found, Apache httpd falls back to the behavior of the
    Script option.
    

    
    Security
    
    
    Be careful when using ScriptInterpreterSource
    Registry with ScriptAlias'ed directories, because
    Apache httpd will try to execute every file within this
    directory. The Registry setting may cause undesired
    program calls on files which are typically not executed. For
    example, the default open command on .htm files on
    most Windows systems will execute Microsoft Internet Explorer, so
    any HTTP request for an .htm file existing within the
    script directory would start the browser in the background on the
    server. This is a good way to crash your system within a minute or
    so.
    
    
    

    
    The option Registry-Strict
    does the same thing as Registry but uses only the
    subkey Shell\ExecCGI\Command. The
    ExecCGI key is not a common one. It must be
    configured manually in the windows registry and hence prevents
    accidental program calls on your system.

    mod_status with ExtendedStatus On
    displays the actual request being handled.
    For historical purposes, only 63 characters of the request
    are actually stored for display purposes. This directive
    controls whether the 1st 63 characters are stored (the previous
    behavior and the default) or if the last 63 characters are. This
    is only applicable, of course, if the length of the request is
    64 characters or greater.
    

    
    If Apache httpd is handling GET /disk1/storage/apache/htdocs/images/imagestore1/food/apples.jpg HTTP/1.1 mod_status displays as follows:

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The ServerAdmin sets the contact address
    that the server includes in any error messages it returns to the
    client. If the httpd doesn't recognize the supplied argument
    as an URL, it
    assumes, that it's an email-address and prepends it with
    mailto: in hyperlink targets. However, it's recommended to
    actually use an email address, since there are a lot of CGI scripts that
    make that assumption. If you want to use an URL, it should point to another
    server under your control. Otherwise users may not be able to contact you in
    case of errors.
    

    
    It may be worth setting up a dedicated address for this, e.g.
    

    
    ServerAdmin www-admin@foo.example.com
    

    
    as users do not always mention that they are talking about the

    Context:virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The ServerAlias directive sets the
    alternate names for a host, for use with name-based virtual hosts. The
    ServerAlias may include wildcards, if appropriate.
    

    
    <VirtualHost *:80>
  ServerName server.example.com
  ServerAlias server server2.example.com server2
  ServerAlias *.example.com
  UseCanonicalName Off
  # ...
</VirtualHost>
    


    
    Name-based virtual hosts for the best-matching set of  <virtualhost>s are processed
    in the order they appear in the configuration.  The first matching ServerName or ServerAlias is used, with no different precedence for wildcards
    (nor for ServerName vs. ServerAlias).  
    

    
    The complete list of names in the <VirtualHost>
    directive are treated just like a (non wildcard)
    ServerAlias.

    ServerName Directive
    

    

    Description:Hostname and port that the server uses to identify
itself
    

    Syntax:ServerName [scheme://]domain-name|ip-address[:port]
    

    Context:server config, virtual host
    

    Status:Core
    

    Module:core
    

    
    
    The ServerName directive sets the
    request scheme, hostname and port that the server uses to identify itself.
    
    

    
    ServerName is used (possibly
    in conjunction with ServerAlias) to uniquely
    identify a virtual host, when using name-based virtual hosts.
    

    
    Additionally, this is used when
    creating self-referential redirection URLs when 
    UseCanonicalName is set to a non-default
    value.
    

    
    For example, if the name of the
    machine hosting the web server is simple.example.com,
    but the machine also has the DNS alias www.example.com
    and you wish the web server to be so identified, the following
    directive should be used:
    

    
    ServerName www.example.com
    


    
    The ServerName directive
    may appear anywhere within the definition of a server. However,
    each appearance overrides the previous appearance (within that
    server).
    

    
    If no ServerName is specified, the
    server attempts to deduce the client visible hostname by first asking 
    the operating system for the system hostname, and if that fails, 
    performing a reverse lookup on an IP address present on the system.
    

    
    If no port is specified in the
    ServerName, then the server will use the
    port from the incoming request. For optimal reliability and
    predictability, you should specify an explicit hostname and port
    using the ServerName directive.
    

    
    If you are using name-based virtual hosts,
    the ServerName inside a
    <VirtualHost>
    section specifies what hostname must appear in the request's
    Host: header to match this virtual host.
    

    
    Sometimes, the server runs behind a device that processes SSL,
    such as a reverse proxy, load balancer or SSL offload
    appliance. When this is the case, specify the
    https:// scheme and the port number to which the
    clients connect in the ServerName directive
    to make sure that the server generates the correct
    self-referential URLs.
    
    

    
    See the description of the
    UseCanonicalName and
    UseCanonicalPhysicalPort directives for
    settings which determine whether self-referential URLs (e.g., by the
    mod_dir module) will refer to the
    specified port, or to the port number given in the client's request.
    
    

    
    
    
    Failure to set ServerName to a name that
    your server can resolve to an IP address will result in a startup
    warning. httpd will then use whatever hostname it can
    determine, using the system's hostname command. This
    will almost never be the hostname you actually want.

    The ServerRoot directive sets the
    directory in which the server lives. Typically it will contain the
    subdirectories conf/ and logs/. Relative
    paths in other configuration directives (such as Include or LoadModule, for example) are taken as
    relative to this directory.
    

    
    ServerRoot "/home/httpd"
    


    
    The default location of ServerRoot may be
    modified by using the --prefix argument to
    configure, and
    most third-party distributions of the server have a different
    default location from the one listed above.

    ServerSignature Directive

    Override:All
    

    Status:Core
    

    Module:core
    

    
    
    The ServerSignature directive allows the
    configuration of a trailing footer line under server-generated
    documents (error messages, mod_proxy ftp directory
    listings, mod_info output, ...). The reason why you
    would want to enable such a footer line is that in a chain of proxies,
    the user often has no possibility to tell which of the chained servers
    actually produced a returned error message.
    

    
    The Off
    setting, which is the default, suppresses the footer line.
    The On setting simply adds a line with the
    server version number and ServerName of the serving virtual host,
    and the EMail setting additionally creates a
    "mailto:" reference to the ServerAdmin of the referenced
    document.
    

    
    The details of the server version number
    presented are controlled by the ServerTokens directive.

    This setting applies to the entire server, and cannot be
    enabled or disabled on a virtualhost-by-virtualhost basis.
    

    
    This directive also controls the
    information presented by the ServerSignature directive.
    

    
    Setting ServerTokens to less than
    minimal is not recommended because it makes it more
    difficult to debug interoperational problems. Also note that
    disabling the Server: header does nothing at all to make your
    server more secure. The idea of "security through obscurity"
    is a myth and leads to a false sense of safety.

    Compatibility:expression argument 2.4.19 and later
    

    
    
    When placed into an .htaccess file or a
    <Directory> or
    <Location>
    section, this directive forces all matching files to be parsed
    through the handler given by
    handler-name. For example, if you had a directory you
    wanted to be parsed entirely as imagemap rule files, regardless
    of extension, you might put the following into an
    .htaccess file in that directory:
    

    
    SetHandler imap-file
    


    
    Another example: if you wanted to have the server display a
    status report whenever a URL of
    http://servername/status was called, you might put
    the following into httpd.conf:
    

    
    <Location "/status">
  SetHandler server-status
</Location>
    


    
    You could also use this directive to configure a particular
    handler for files with a particular file extension. For example:
    

    
    <FilesMatch "\.php$">
    SetHandler application/x-httpd-php
</FilesMatch>
    


    
    String-valued expressions can be used to reference per-request 
    variables, including backreferences to named regular expressions:
    

    
    <LocationMatch ^/app/(?<sub>[^/]+)/>
     SetHandler "proxy:unix:/var/run/app_%{env:MATCH_sub}.sock|fcgi://localhost:8080"
</LocationMatch>
    


    
    You can override an earlier defined SetHandler
    directive by using the value None.
    

    
    Note
    
    
    Because SetHandler overrides default handlers,
    normal behavior such as handling of URLs ending in a slash (/) as
    directories or index files is suppressed.

    Compatibility:Added in 2.4.49
    

    
    
    By default, the server will respond to requests for any hostname,
    including requests addressed to unexpected or unconfigured hostnames. 
    While this is convenient, it is sometimes desirable to limit what hostnames
    a backend application handles since it will often generate self-referential
    responses.
    

    
    By setting StrictHostCheck to ON,
    the server will return an HTTP 400 error if the requested hostname
    hasn't been explicitly listed by either ServerName or ServerAlias in the virtual host that best matches the
    details of the incoming connection.
    

   
    This directive also allows matching of the requested hostname to hostnames
   specified within the opening VirtualHost
   tag, which is a relatively obscure configuration mechanism that acts like
   additional ServerAlias entries.
    

   
    This directive has no affect in non-default virtual hosts. The value
   inherited from the global server configuration, or the default virtualhost 
   for the ip:port the underlying connection, determine the effective value.

    TraceEnable on permits TRACE requests per
    RFC 2616, which disallows any request body to accompany the request.
    TraceEnable off causes the core server and
    mod_proxy to return a 405 (Method not
    allowed) error to the client.
    

    
    Finally, for testing and diagnostic purposes only, request
    bodies may be allowed using the non-compliant TraceEnable
    extended directive.  The core (as an origin server) will
    restrict the request body to 64Kb (plus 8Kb for chunk headers if
    Transfer-Encoding: chunked is used).  The core will
    reflect the full headers and all chunk headers with the response
    body.  As a proxy server, the request body is not restricted to 64Kb.
    

    
    Note
    

    
    Despite claims to the contrary, enabling the TRACE
    method does not expose any security vulnerability in Apache httpd.
    The TRACE method is defined by the HTTP/1.1
    specification and implementations are expected to support it.

    UnDefine Directive
    

    

    Description:Undefine the existence of a variable
    

    Syntax:UnDefine parameter-name
    

    Context:server config
    

    Status:Core
    

    Module:core
    

    
    
    Undoes the effect of a Define or
    of passing a -D argument to httpd.
    
    
    This directive can be used to toggle the use of <IfDefine> sections without needing to alter
    -D arguments in any startup scripts.
    

    
    Variable names may not contain colon ":" characters, to avoid clashes
    with RewriteMap's syntax.
    

    
    Virtual Host scope and pitfalls
    
      
    While this directive is supported in virtual host context,
         the changes it makes are visible to any later configuration
         directives, beyond any enclosing virtual host.

    UseCanonicalName Directive
    

    

    Description:Configures how the server determines its own name and
port
    

    Syntax:UseCanonicalName On|Off|DNS
    

    Default:UseCanonicalName Off
    

    Context:server config, virtual host, directory
    

    Status:Core
    

    Module:core
    

    
    
    In many situations Apache httpd must construct a self-referential
    URL -- that is, a URL that refers back to the same server. With
    UseCanonicalName On Apache httpd will use the hostname and port
    specified in the ServerName
    directive to construct the canonical name for the server. This name
    is used in all self-referential URLs, and for the values of
    SERVER_NAME and SERVER_PORT in CGIs.
    

    
    With UseCanonicalName Off Apache httpd will form
    self-referential URLs using the hostname and port supplied by
    the client if any are supplied (otherwise it will use the
    canonical name, as defined above). These values are the same
    that are used to implement name-based virtual hosts
    and are available with the same clients. The CGI variables
    SERVER_NAME and SERVER_PORT will be
    constructed from the client supplied values as well.
    

    
    An example where this may be useful is on an intranet server
    where you have users connecting to the machine using short
    names such as www. You'll notice that if the users
    type a shortname and a URL which is a directory, such as
    http://www/splat, without the trailing
    slash, then Apache httpd will redirect them to
    http://www.example.com/splat/. If you have
    authentication enabled, this will cause the user to have to
    authenticate twice (once for www and once again
    for www.example.com -- see 
    the FAQ on this subject for more information). But if
    UseCanonicalName is set Off, then
    Apache httpd will redirect to http://www/splat/.
    

    
    There is a third option, UseCanonicalName DNS,
    which is intended for use with mass IP-based virtual hosting to
    support ancient clients that do not provide a
    Host: header. With this option, Apache httpd does a
    reverse DNS lookup on the server IP address that the client
    connected to in order to work out self-referential URLs.
    

    
    Warning
    
    
    If CGIs make assumptions about the values of SERVER_NAME,
    they may be broken by this option. The client is essentially free
    to give whatever value they want as a hostname. But if the CGI is
    only using SERVER_NAME to construct self-referential URLs,
    then it should be just fine.

    UseCanonicalPhysicalPort Directive
    

    

    Description:Configures how the server determines its own port
    

    Syntax:UseCanonicalPhysicalPort On|Off
    

    Default:UseCanonicalPhysicalPort Off
    

    Context:server config, virtual host, directory
    

    Status:Core
    

    Module:core
    

    
    
    In many situations Apache httpd must construct a self-referential
    URL -- that is, a URL that refers back to the same server. With
    UseCanonicalPhysicalPort On, Apache httpd will, when
    constructing the canonical port for the server to honor
    the UseCanonicalName directive,
    provide the actual physical port number being used by this request
    as a potential port. With UseCanonicalPhysicalPort Off,
    Apache httpd will not ever use the actual physical port number, instead
    relying on all configured information to construct a valid port number.
    

    
    Note
    
    
    The ordering of the lookup when the physical port is used is as
    follows:
    
     
    
     
    UseCanonicalName On
    
     
    
     
      
      
    1. Port provided in Servername
      2. 
      
    2. Physical port
      3. 
      
    3. Default port
      4. 
     
    
     
    
     
    UseCanonicalName Off | DNS
    
     
    
     
      
      
    1. Parsed port from Host: header
      2. 
      
    2. Physical port
      3. 
      
    3. Port provided in Servername
      4. 
      
    4. Default port
      5. 
     
    
     
    
     
    

    
    With UseCanonicalPhysicalPort Off, the
    physical ports are removed from the ordering.

    <VirtualHost> Directive
    

    

    Description:Contains directives that apply only to a specific
hostname or IP address
    

    Syntax:<VirtualHost
    addr[:port] [addr[:port]]
    ...> ... </VirtualHost>
    

    Context:server config
    

    Status:Core
    

    Module:core
    

    
    
    <VirtualHost> and
    </VirtualHost> are used to enclose a group of
    directives that will apply only to a particular virtual host. Any
    directive that is allowed in a virtual host context may be
    used. When the server receives a request for a document on a
    particular virtual host, it uses the configuration directives
    enclosed in the <VirtualHost>
    section. Addr can be any of the following, optionally followed by
    a colon and a port number (or *):
    

    
      
      
    • The IP address of the virtual host;
      • 

      
    • A fully qualified domain name for the IP address of the
      virtual host (not recommended);
      • 

      
    • The character *, which acts as a wildcard and matches
      any IP address.
      • 

      
    • The string _default_, which is an alias for *
      • 

    
    

    
    <VirtualHost 10.1.2.3:80>
  ServerAdmin webmaster@host.example.com
  DocumentRoot "/www/docs/host.example.com"
  ServerName host.example.com
  ErrorLog "logs/host.example.com-error_log"
  TransferLog "logs/host.example.com-access_log"
</VirtualHost>
    



    
    IPv6 addresses must be specified in square brackets because
    the optional port number could not be determined otherwise.  An
    IPv6 example is shown below:
    

    
    <VirtualHost [2001:db8::a00:20ff:fea7:ccea]:80>
  ServerAdmin webmaster@host.example.com
  DocumentRoot "/www/docs/host.example.com"
  ServerName host.example.com
  ErrorLog "logs/host.example.com-error_log"
  TransferLog "logs/host.example.com-access_log"
</VirtualHost>
    


    
    Each Virtual Host must correspond to a different IP address,
    different port number, or a different host name for the server,
    in the former case the server machine must be configured to
    accept IP packets for multiple addresses. (If the machine does
    not have multiple network interfaces, then this can be
    accomplished with the ifconfig alias command -- if
    your OS supports it).
    

    
    Note
    
    
    The use of <VirtualHost> does
    not affect what addresses Apache httpd listens on. You
    may need to ensure that Apache httpd is listening on the correct addresses
    using Listen.
    
    
    

    
    A ServerName should be
    specified inside each <VirtualHost> block. If it is absent, the
    ServerName from the "main"
    server configuration will be inherited.
    

    
    When a request is received, the server first maps it to the best matching
    <VirtualHost> based on the local
    IP address and port combination only.  Non-wildcards have a higher
    precedence. If no match based on IP and port occurs at all, the
    "main" server configuration is used.
    

    
    If multiple virtual hosts contain the best matching IP address and port,
    the server selects from these virtual hosts the best match based on the
    requested hostname.  If no matching name-based virtual host is found,
    then the first listed virtual host that matched the IP address will be
    used.  As a consequence, the first listed virtual host for a given IP address
    and port combination is the default virtual host for that IP and port
    combination.
    

    
    Security
    
    
    See the security tips
    document for details on why your security could be compromised if the
    directory where log files are stored is writable by anyone other
    than the user that starts the server.

    Ce document décrit les termes utilisés pour décrire chaque directive de configuration d'Apache.
    

    


    top
    

    

    Description
    


    Une brève description des fonctions de cette directive.
    

    top
    

    

    Syntaxe
    

    
    Ce terme introduit le format sous lequel la directive doit
    apparaître dans le fichier de configuration. Cette syntaxe est très
    spécifique à la directive et est décrite en détail dans la
    définition de cette dernière. En général, le nom de la directive est
    suivi d'un ou plusieurs arguments séparés par des espaces. Si un
    argument contient un espace, il doit être entouré de guillemets. Les
    arguments optionnels sont entourés de crochets. Lorsqu'un argument
    accepte une valeur parmi une liste de valeurs possibles, cette liste
    est spécifiée en séparant les valeurs par une barre verticale "|".
    Les textes littéraux sont présentés dans la fonte par défaut, alors
    que les types d'argument pour lesquels une substitution est
    nécessaire sont en gras. La syntaxe des directives
    acceptant un nombre variable d'arguments se termine par "...", ce
    qui indique que le dernier argument peut être répété.
    

    
    Les directives utilisent un grand nombre de types d'arguments
    différents. Les plus courants sont définis ci-dessous.
    

    
    
      
    URL
    

      
    Un Localisateur de Ressource Uniforme (Uniform Resource
      Locator) complet comportant un protocole, un nom d'hôte et un nom
      de chemin optionnel comme dans
      http://www.example.com/chemin/vers/fichier.html
    

      
    chemin-URL
    

      
    La partie de l'url qui suit le protocole et le nom
      d'hôte comme dans /chemin/vers/fichier.html. Le
      chemin-URL représente la ressource vue du web, et est
      différente de la représentation de cette même ressource vue du
      système de fichiers.
    

      
    chemin-fichier
    

      
    Le chemin d'un fichier dans le système de fichiers local
      commençant par le répertoire racine comme dans
      /usr/local/apache/htdocs/chemin/vers/fichier.html.
      Sauf mention contraire, un chemin-fichier qui ne commence
      pas par un slash sera considéré comme relatif au répertoire défini
      par la directive ServerRoot.
    

      
    chemin-répertoire
    

      
    Le chemin d'un répertoire dans le système de fichiers local
      commençant par le répertoire racine comme dans
      /usr/local/apache/htdocs/chemin/vers/.
    

      
    nom-fichier
    

      
    Le nom d'un fichier sans son chemin comme dans
      fichier.html.
    

      
    regex
    

      
    Une expression rationnelle
      compatible Perl. La définition de la directive spécifiera à quoi
      regex sera comparée.
    

      
    extension
    

      
    En général, c'est la partie du nom de fichier qui
      suit le dernier point. Cependant, Apache reconnaît plusieurs
      extensions de noms de fichiers ; ainsi, si un nom de
      fichier
      contient plusieurs points, chacune des parties du nom de fichier
      séparées par des points et situées après le premier point est une
      extension. Par exemple, le nom de fichier
      fichier.html.en comporte deux extensions :
      .html et .en. Pour les directives
      Apache, vous pouvez spécifier les extensions avec ou sans
      le point initial. Enfin, les extensions ne sont pas
      sensibles à la casse.
    

      
    MIME-type
    

      
    Une méthode de description du format d'un fichier consistant
      en un type de format majeur et un type de format mineur séparés
      par un slash comme dans text/html.
    

      
    env-variable
    

      
    Le nom d'une variable
      d'environnement définie au cours du processus de configuration
      d'Apache. Notez qu'elle peut être différente d'une variable
      d'environnement du système d'exploitation. Voir la documentation sur les variables d'environnement
      pour plus de détails.
    
    
    

    top
    

    

    Défaut
    

    
    Si la directive possède une valeur par défaut (en d'autres
    termes, si le serveur Web Apache se comporte comme si vous l'aviez
    définie à une valeur particulière, alors que vous l'avez omise dans
    votre configuration), elle est spécifiée ici. Si la directive ne
    possède pas de valeur par défaut, cette section doit spécifier
    "Aucune". Notez que la valeur par défaut dont il est
    question n'est pas nécessairement la même que la valeur attribuée à
    la directive dans le fichier httpd.conf par défaut distribué avec le
    serveur.
    

    top
    

    

    Contexte
    

    
    Indique les parties des fichiers de configuration du serveur
    où cette directive est valide. Il s'agit d'une liste d'une ou
    plusieurs des valeurs suivantes séparées par des virgules :
    

    
    
      
    configuration globale
    

      
    Signifie que la directive peut être utilisée dans les fichiers
      de configuration globale (par exemple httpd.conf),
      mais pas à l'intérieur d'un conteneur <VirtualHost> ou <Directory>. De même, elle
      n'est pas valide dans les fichiers .htaccess.
    

      
    serveur virtuel
    

      
    Signifie que la directive peut apparaître à l'intérieur d'un
      conteneur <VirtualHost> dans les fichiers de
      configuration du serveur.
    

      
    répertoire
    

      
    Une directive spécifiée comme valide dans ce contexte peut
      être utilisée à l'intérieur de conteneurs <Directory>, <Location>, <Files>, <If>, et <Proxy> dans les
      fichiers de configuration du serveur, en tenant compte des
      restrictions précisées dans la documentation sur les Sections de configuration.
    

      
    .htaccess
    

      
    Si une directive est valide dans ce contexte, cela signifie
      qu'elle peut apparaître à l'intérieur de fichiers de configuration
      de niveau répertoire .htaccess. Elle sera ou
      ne sera pas traitée, selon la définition de l'option overrides pour le contexte courant.
    
    
    

    
    La directive n'est autorisée que dans le contexte
    désigné ; si vous essayez de l'utiliser ailleurs, vous générerez une
    erreur de configuration qui va soit empêcher le serveur de traiter
    les requêtes correctement dans ce contexte, soit tout simplement
    empêcher le serveur de fonctionner -- en d'autres termes, le serveur
    refusera de démarrer.
    

    
    Les lieux de définition valides pour une directive résultent en
    fait d'un
    OU logique de tous les contextes spécifiés. En d'autres termes, une
    directive spécifiée comme valide dans "configuration globale,
    .htaccess" peut être utilisée dans le fichier
    httpd.conf et dans les fichiers .htaccess,
    mais pas dans un conteneur <Directory> ou <VirtualHost>.
    

    top
    

    

    Surcharge/Écrasement
    

    
    Ce terme indique quelle autorisation de surcharge ("override") doit être
    active pour que la directive puisse être traitée lorsqu'elle
    apparaît dans un fichier .htaccess. Si le context de la directive ne lui permet pas
    d'apparaître dans un fichier .htaccess, aucun contexte
    ne sera spécifié.
    

    
    Les autorisations de surcharge sont activées via la directive
    AllowOverride, et possèdent une
    portée particulière, comme un répertoire et tous ses
    sous-répertoires, sauf si une autre directive AllowOverride apparaît à un niveau
    inférieur. La documentation pour cette directive spécifie aussi les
    noms d'autorisations de surcharge disponibles.
    

    top
    

    

    Statut
    

    
    Cet attribut indique le degré de rapprochement de la directive du
    coeur d'Apache ; en d'autres termes, vous pouvez être amené à
    recompiler le serveur avec un jeu de modules supplémentaires pour
    pouvoir utiliser la directive, et ainsi accéder à ses
    fonctionnalités. Les valeurs possible pour cet attribut sont :
    

    
    
      
    Core
    

      
    Lorsqu'une directive a pour statut "Core", cela signifie
      qu'elle fait partie du coeur du serveur web Apache, et est de ce
      fait toujours disponible.
    

      
    MPM
    

      
    Une directive dont le statut est "MPM" est fournie par un module Multi-Processus. Ce type de
      directive sera disponible si et seulement si vous utilisez un des
      MPMs spécifiés dans la ligne Module de la
      définition de la directive.
    

      
    Base
    

      
    Une directive dont le statut est "Base" est fournie par un des
      modules Apache standards qui sont compilés dans le serveur par
      défaut, et sont de ce fait toujours disponibles, sauf si vous avez
      fait en sorte de les supprimer de votre configuration.
    

      
    Extension
    

      
    Une directive dont le statut est "Extension" est fournie par
      un des modules inclus dans le kit du serveur Apache, mais qui ne
      sont pas compilés dans le serveur par défaut. Pour activer la
      directive et accéder à ses fonctionnalités, vous devez modifier
      les fichiers de configuration de la compilation du serveur, et
      recompiler Apache.
    

      
    Expérimental
    

      
    Le statut "Expérimental" indique que la directive fait partie
      du kit Apache, mais que vous l'utilisez à vos risques et périls.
      La directive est documentée à titre d'exhaustivité, et n'est pas
      obligatoirement supportée. Le module qui fournit la directive peut
      être compilé par défaut dans le serveur ou non ; consultez le haut
      de la page qui décrit la directive et son module pour vérifier sa
      disponibilité.
    
    
    

    top
    

    

    Module
    

    
    Il s'agit d'une simple liste des noms des modules sources qui
    fournissent la directive.
    

    top
    

    

    Compatibilité
    

    
    Si la directive ne faisait pas partie de la distribution
    originale d'Apache version 2, la version dans laquelle elle a été
    introduite est indiquée ici. Cette section indique aussi si la
    directive n'est disponible que sur certaines plates-formes.

    Request Counting Algorithm
    
    
    
    Enabled via lbmethod=byrequests, the idea behind this
    scheduler is that we distribute the requests among the
    various workers to ensure that each gets their configured share
    of the number of requests. It works as follows:
    

    
    lbfactor is how much we expect this worker
    to work, or the workers' work quota. This is
    a normalized value representing their "share" of the amount of
    work to be done.
    

    
    lbstatus is how urgent this worker has to work
    to fulfill its quota of work.
    

    
    The worker is a member of the load balancer,
    usually a remote host serving one of the supported protocols.
    

    
    We distribute each worker's work quota to the worker, and then look
    which of them needs to work most urgently (biggest lbstatus).  This
    worker is then selected for work, and its lbstatus reduced by the
    total work quota we distributed to all workers.  Thus the sum of all
    lbstatus does not change(*) and we distribute the requests
    as desired.
    

    
    If some workers are disabled, the others will
    still be scheduled correctly.
    

    
    for each worker in workers
    worker lbstatus += worker lbfactor
    total factor    += worker lbfactor
    if worker lbstatus > candidate lbstatus
        candidate = worker

candidate lbstatus -= total factor
    

    
    If a balancer is configured as follows:
    

    
    worker
        a
        b
        c
        d
    

    lbfactor
        25
        25
        25
        25
    

    lbstatus
        0
        0
        0
        0
    

    

    
    And b gets disabled, the following schedule is produced:
    

    
    worker
        a
        b
        c
        d
    

    lbstatus
        -50
        0
        25
        25
    

    lbstatus
        -25
        0
        -25
        50
    

    lbstatus
        0
        0
        0
        0
    

    (repeat)
    

    

    
    That is it schedules: a c d
    a c d a c
    d ... Please note that:
    

    
    worker
        a
        b
        c
        d
    

    lbfactor
        25
        25
        25
        25
    

    

    
    Has the exact same behavior as:
    

    
    worker
        a
        b
        c
        d
    

    lbfactor
        1
        1
        1
        1
    

    

    
    This is because all values of lbfactor are normalized
    with respect to the others. For:
    

    
    worker
        a
        b
        c
    

    lbfactor
        1
        4
        1
    

    

    
    worker b will, on average, get 4 times the requests
    that a and c will.
    

    
    The following asymmetric configuration works as one would expect:
    

    
    worker
        a
        b
    

    lbfactor
        70
        30
    

     
    

    lbstatus
        -30
        30
    

    lbstatus
        40
        -40
    

    lbstatus
        10
        -10
    

    lbstatus
        -20
        20
    

    lbstatus
        -50
        50
    

    lbstatus
        20
        -20
    

    lbstatus
        -10
        10
    

    lbstatus
        -40
        40
    

    lbstatus
        30
        -30
    

    lbstatus
        0
        0
    

    (repeat)
    

    

    
    That is after 10 schedules, the schedule repeats and 7 a
    are selected with 3 b interspersed.

    Açıklama:Kitlesel sanal konakların devingen olarak yapılandırılmasını sağlar
    

    Durum:Eklenti
    

    Modül Betimleyici:vhost_alias_module
    

    Kaynak Dosyası:mod_vhost_alias.c
    

    Özet
    

    
    Bu modül, hangi dosyaların sunulacağını saptamak için dosya yolunun
      parçası olarak HTTP isteğinin Host: başlığının ve/veya IP
      adresinin kullanılmasını mümkün kılarak devingen yapılandırmalı sanal
      konaklar oluşturur. Böylece benzer yapılandırmaya sahip çok büyük sayıda
      sanal konak kullanımı kolaşlaşır.
    

    
    Bilginize
    
      
    URI’leri dosya isimlerine dönüştürmek için mod_alias
        veya mod_userdir kullanılmışsa bunlar
        mod_vhost_alias yönergeleri tarafından aşağıda
        açıklandığı gibi geçersiz kılınırlar. Örneğin, aşağıdaki yapılandırma
        her durumda /cgi-bin/script.pl betiğini 
        /usr/local/apache2/cgi-bin/script.pl betiğine eşleyecektir:
    

      
    ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/"
VirtualScriptAlias "/nerede/bilinmiyor/%0/cgi-bin/"

    Dizin İsimlerinin Elde Edilmesi
    
    

    
    Bu modüldeki tüm yönergeler bir dizgeyi bir dosya yoluna dönüştürerek
      çalışırlar. Dönüşüm dizgesi (bundan sonra “isim” diyeceğiz) ya sunucu
      ismi olur (bunun nasıl belirlendiğini öğrenmek için UseCanonicalName yönergesine bakınız) ya da
      sunucu üzerindeki sanal konağın IP adresi olur. Dönüşümü,
      printf’inkilerin benzeri birkaç biçem belirteci
      denetler:
    


    


    %%
Bir % imi yerleştirir.
    


    %p
Sanal konağın IP adresini yerleştirir.
    


    %N.M
İsmin parçalarını yerleştirir.
    


    

    
    N ve M ismin alt dizgelerini belirtmek için
      kullanılır. N, ismin noktalarla ayrılmış bileşenlerinden
      seçim yaparken M, N ile seçilen parçadan
      karakter seçmekte kullanılır. M isteğe bağlı olup mevcut
      olmaması halinde öntanımlı olarak sıfırdır. Noktanın varlığı
      M’nin varlığına bağlıdır. Dönüşüm şöyle uygulanır:
    

    
    
      
      
    0
      ismin tamamı
    

      
    1
      ilk parça
    

      
    2
      ikinci parça
    

      
    -1
      son parça
    

      
    -2
      sondan bir önceki parça
    

      
    2+
      ikinci parça ve sonraki parçaların hepsi
    

      
    -2+
      sondan bir önceki parça ve daha önceki parçaların hepsi
    

      
    1+ ve -1+
      0 ile aynı
    
    
    

    
    N veya M parça sayısından büyükse dönüşüm
      dizgesi sadece alt çizgi karakterini içerir.

    Örnekler
    
    

    
    Sunucu yapılandırma dosyanızda isme dayalı sanal konaklar için
      aşağıdaki yönergeler kullanılıyor olsun:
    

    
    UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/sankonlar/%0"
    


    
    http://example.com/dizin/dosya.html için yapılan bir istek
      /usr/local/apache/sankonlar/example.com/dizin/dosya.html
      dosyası ile yerine getirilecektir.
    

    
    Çok büyük sayıda sanal konak için sankonlar dizininin
      boyutlarını küçük tutmak amacıyla dosyalar düzenlenebilir. Bunu
      yapılandırma dosyanızda şöyle yapabilirsiniz:
    

    
    UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/sankonlar/%3+/%2.1/%2.2/%2.3/%2"
    


    
    http://falan.filan.example.com/dizin/dosya.html için
      yapılan bir istek
    /usr/local/apache/sankonlar/example.com/f/i/l/filan/dizin/dosya.html
       ile yerine getirilecektir.
    

    
    Bu sefer de parçaları ismin sonundan toplayalım: 
    

    
    VirtualDocumentRoot "/usr/local/apache/sankonlar/%3+/%2.-1/%2.-2/%2.-3/%2"
    


    
    Bu durumda istek
    /usr/local/apache/sankonlar/example.com/n/a/l/filan/dizin/dosya.html
    ile karşılanırdı.
    

    
    Şöyle bir şey de yapabilirsiniz:
    

    
    VirtualDocumentRoot "/usr/local/apache/sankonlar/%3+/%2.1/%2.2/%2.3/%2.4+"
    


    
    Bu örnek için istek
      /usr/local/apache/sankonlar/example.com/f/i/l/an/dizin/dosya.html
       dosyasından karşılanırdı.
    

    
    Kullanıcıların çoğunun ortak isteği, istenen konak adının uzunluğu veya
      sayısı için endişelenmeksizin çok sayıda belge köküne çok sayıda alan
      adından erişilebilmesidir. Eğer istenen konak adı
      www.domain.example.com değil de
      sub.www.domain.example.com ise %3+ kullanımı, belge kök
      dizininin düşünüldüğü gibi example.com değil
      /usr/local/apache/vhosts/domain.example.com/... olmasını
      sağlar. Böyle durumlarda, daima alan adı ve tld ile sonuçlanan
      %-2.0.%-1.0 birleşiminin kullanımı daha yararlı olabilir.
      Böylece, tüm ilk, ikinci ve üçüncü seviye alt alan adlarını aynı dizine
      yönlendirecek bir yapılandırma yapılabilir:
    

    
    VirtualDocumentRoot "/usr/local/apache/vhosts/%-2.0.%-1.0"
    


    
    Yukarıdaki örnekte, example.com,
      www.example.com ve hatta www.sub.example.com
      bile /usr/local/apache/vhosts/example.com dizinine
      yönlendirilecektir.
    

    
    IP’ye dayalı sanal konaklar için yapılandırma dosyanızda şu satırlar
      olabilirdi:
    

    
    UseCanonicalName DNS
VirtualDocumentRootIP "/usr/local/apache/sankonlar/%1/%2/%3/%4/belgeler"
VirtualScriptAliasIP  "/usr/local/apache/sankonlar/%1/%2/%3/%4/cgi-bin"
    


    
    http://falan.filan.example.com/dizin/dosya.html için
      yapılan bir istek eğer falan.filan.example.com’un IP adresi
      10.20.30.40 olsaydı,
      /usr/local/apache/sankonlar/10/20/30/40/belgeler/dizin/dosya.html
       dosyası ile karşılanırdı.
      http://falan.filan.example.com/cgi-bin/betik.pl için yapılan
      bir istek ise
      /usr/local/apache/sankonlar/10/20/30/40/cgi-bin/betik.pl
      betiğinin çalıştırılması ile sağlanırdı.
    

    
    Bir VirtualDocumentRoot yönergesinin .
      karakterini içermesini isterseniz, bir biçem belirteci ile karışıklığa
      sebep olmaksızın bunu şöyle sağlayabilirsiniz:
    

    
    VirtualDocumentRoot "/usr/local/apache/sankonlar/%2.0.%3.0"
    


    
    Bu durumda http://falan.filan.example.com/dizin/dosya.html
      için yapılan bir istek
      /usr/local/apache/sankonlar/filan.mesela/dizin/dosya.html
      dosyası ile karşılanacaktır.
    

    
    LogFormat  yönergesinin
      %V ve %A biçem belirteçleri bu modülle
      birlikte kullanıldığında çok yararlı olurlar.

      hesaplanan-dizin’in dönüşüm sonucu DocumentRoot yönergesinin değeriymiş gibi
      belge ağacının kök dizini olarak kullanılır.
      hesaplanan-dizin yerine none

      yer alamaz.
    

    
    Bilginize
    
      VirtualDocumentRoot yönergesi aynı bağlamda veya
      alt bağlamlarda da kullanılabilen DocumentRoot yönergelerini geçersiz kılar.
      Genel sunucu etki alanına bir VirtualDocumentRoot
      konulması, daha sonra yer alan her sanal konak tanımı içinde
      VirtualDocumentRoot yönergesine None
      atamadıkça bu sanal konaklarda yapılmış DocumentRoot atamalarını geçersiz kılacaktır.

    Description:Journalisation légale des requêtes envoyées au
serveur
    

    Statut:Extension
    

    Identificateur de Module:log_forensic_module

    Sommaire
    

    
    Ce module permet la journalisation légale des requêtes client. La
    journalisation s'effectuant avant et après le traitement de la
    requête, le journal légal contient deux lignes pour chaque requête.
    Le processus de journalisation légale est très strict, à savoir
    :
    

    
      
    
    • Le format est figé. Vous ne pouvez pas modifier le format du
    journal à l'exécution.
      • 
    
    • S'il ne peut pas enregistrer ses données, le processus enfant se
    termine aussitôt, et peut éventuellement enregistrer un vidage
    mémoire (selon la définition de la directive CoreDumpDirectory).
      • 
    
    

    
    Pour interpréter les données du journal légal, vous pouvez vous
    aider du script check_forensic qui se trouve dans le
    répertoire support de la distribution.
    
    
    Note de traduction : le terme "légal" utilisé dans le présent document ne suggère aucunement que
    ce module apporte une valeur juridique aux journaux. Il est à comprendre dans le contexte
    similaire à ce que l'on trouve en analyse medico-légale. En d'autres termes, la finalité de ce module
    est de simplifier les opérations d'investigation autour du traitement des requêtes par le serveur.

    Format du journal Forensic
    
    
    Chaque requête fait l'objet d'une double journalisation. La
    requête est journalisée une première fois avant son traitement
    (c'est à dire après la réception des en-têtes). La deuxième entrée
    du journal est écrite après le traitement de la requête, en
    fait au moment de la journalisation habituelle.
    

    
    Un identifiant unique est attribué à chaque requête afin de
    pouvoir l'identifier. Cette identifiant légal peut faire l'objet
    d'un enregistrement dans le journal standard en utilisant l'élément
    de chaîne de format %{forensic-id}n. Si vous utilisez
    mod_unique_id, c'est l'identifiant qu'il génère qui
    sera utilisé.
    

    
    La première partie de la journalisation de la requête enregistre
    l'identifiant légal, la ligne de la requête et tous les en-têtes
    reçus séparés par des caractères pipe (|). Voici à
    titre d'exemple à quoi pourrait ressembler une telle entrée (tout
    étant rassemblé sur une seule ligne) :
    

    
    
        +yQtJf8CoAB4AAFNXBIEAAAAA|GET /manual/de/images/down.gif
        HTTP/1.1|Host:localhost%3a8080|User-Agent:Mozilla/5.0 (X11;
        U; Linux i686; en-US; rv%3a1.6) Gecko/20040216
        Firefox/0.8|Accept:image/png, etc...
    
    

    
    Le caractère plus ('+') de début indique qu'il s'agit de la
    première entrée de journal pour cette requête. La seconde entrée ne
    contiendra qu'un caractère moins ('-') suivi de l'identifiant :
    

    
    
      -yQtJf8CoAB4AAFNXBIEAAAAA
    
    

    
    Le script check_forensic prend comme argument le nom
    du fichier journal. Il recherche ces paires d'identifiants
    +/- et affiche un message d'erreur si la
    journalisation d'une requête n'est pas complète.

    Considérations à propos de
sécurité
    
    
    Voir le document conseils en matière de
    sécurité pour des détails sur les raisons pour lesquelles votre
    sécurité pourrait être compromise si le répertoire dans lequel les
    fichiers journaux sont stockés sont inscriptibles par tout autre
    utilisateur que celui qui démarre le serveur.
    
    
    Les fichiers journaux peuvent contenir des données sensibles
    comme le contenu des en-têtes Authorization: (qui
    peuvent contenir des mots de passe) ; ils ne doivent donc être
    lisibles que par l'utilisateur qui démarre le serveur.

    Directive ForensicLog
    

    

    Description:Définit le nom de fichier du journal légal
    

    Syntaxe:ForensicLog nom-fichier|pipe
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_log_forensic
    

    
    
    La directive ForensicLog permet de
    contrôler la journalisation des requêtes à des fins d'analyse
    légale. Chaque entrée du journal se voit assigner un identifiant
    unique qui peut être associé à la requête en utilisant la directive
    CustomLog habituelle.
    mod_log_forensic crée un élément nommé
    forensic-id, qui peut être ajouté au journal standard
    en utilisant l'élément de format %{forensic-id}n.
    

    
    L'argument, qui permet de spécifier l'emplacement vers lequel le
    journal légal sera écrit, peut contenir les deux types de valeurs
    suivants :
    

    
    
      
    nom-fichier
    
      
    Un nom de fichier relatif au répertoire défini par la
      directive ServerRoot.
    

      
    pipe
    
      
    Le caractère pipe "|", suivi du chemin vers un
      programme qui recevra les informations de la journalisation sur
      son entrée standard. Le nom du programme peut être relatif au
      répertoire défini par la directive ServerRoot.

      
    Sécurité :
    
      
    Si les journaux sont redirigés vers un programme, ce dernier
      s'exécutera sous l'utilisateur qui a démarré
      httpd. Ce sera l'utilisateur root si le serveur
      a été démarré par root ; vérifiez que le programme est
      sécurisé ou passe sous le contrôle d'un utilisateur possédant des
      droits restreints.
    
      
    

      
    Note
    
        
    Lors de la spécification d'un chemin de fichier sur les
	plate-formes non-Unix, il faut prendre soin de ne pas oublier
	que seuls les slashes directs doivent être utilisés, même si la
	plate-forme autorise l'emploi d'anti-slashes. D'une manière
	générale, c'est une bonne idée que de n'utiliser que des slashes
	directs dans les fichiers de configuration.

    Description:Loading of executable code and
modules into the server at start-up or restart time
    

    Status:Extension
    

    Module Identifier:so_module
    

    Source File:mod_so.c
    

    Compatibility:This is a Base module (always included) on
Windows
    

    Summary
    


    
    On selected operating systems this module can be used to
    load modules into Apache HTTP Server at runtime via the Dynamic Shared Object (DSO) mechanism,
    rather than requiring a recompilation.
    

    
    On Unix, the loaded code typically comes from shared object
    files (usually with .so extension), on Windows
    this may either be the .so or .dll
    extension.
    

    
    Warning
    
    
    Modules built for one major version of the Apache HTTP Server
    will generally not work on another. (e.g. 1.3 vs. 2.0, or 2.0 vs.
    2.2) There are usually API changes between one major version and
    another that require that modules be modified to work with the new
    version.

    Creating Loadable Modules for Windows
    

    
    Note
    
    
    On Windows, where loadable files typically have a file extension
    of .dll, Apache httpd modules are called
    mod_whatever.so, just as they are on other platforms.
    However, you may encounter third-party modules, such as PHP for
    example, that continue to use the .dll convention.
    

    
    While mod_so still loads modules with
    ApacheModuleFoo.dll names, the new naming convention is
    preferred; if you are converting your loadable module for 2.0,
    please fix the name to this 2.0 convention.
    

    
    The Apache httpd module API is unchanged between the Unix and
    Windows versions. Many modules will run on Windows with no or
    little change from Unix, although others rely on aspects of the
    Unix architecture which are not present in Windows, and will
    not work.
    

    
    When a module does work, it can be added to the server in
    one of two ways. As with Unix, it can be compiled into the
    server. Because Apache httpd for Windows does not have the
    Configure program of Apache httpd for Unix, the module's
    source file must be added to the ApacheCore project file, and
    its symbols must be added to the
    os\win32\modules.c file.
    

    
    The second way is to compile the module as a DLL, a shared
    library that can be loaded into the server at runtime, using
    the LoadModule
    directive. These module DLLs can be distributed and run on any
    Apache httpd for Windows installation, without recompilation of the
    server.
    

    
    To create a module DLL, a small change is necessary to the
    module's source file: The module record must be exported from
    the DLL (which will be created later; see below). To do this,
    add the AP_MODULE_DECLARE_DATA (defined in the
    Apache httpd header files) to your module's module record definition.
    For example, if your module has:
    


    
    module foo_module;

    

    
    Replace the above with:
    

    
    module AP_MODULE_DECLARE_DATA foo_module;

    

    
    Note that this will only be activated on Windows, so the
    module can continue to be used, unchanged, with Unix if needed.
    Also, if you are familiar with .DEF files, you can
    export the module record with that method instead.
    

    
    Now, create a DLL containing your module. You will need to
    link this against the libhttpd.lib export library that is
    created when the libhttpd.dll shared library is compiled. You
    may also have to change the compiler settings to ensure that
    the Apache httpd header files are correctly located. You can find
    this library in your server root's modules directory. It is
    best to grab an existing module .dsp file from the tree to
    assure the build environment is configured correctly, or
    alternately compare the compiler and link options to your
    .dsp.
    

    
    This should create a DLL version of your module. Now simply
    place it in the modules directory of your server
    root, and use the LoadModule
    directive to load it.

    LoadFile Directive
    

    

    Description:Link in the named object file or library
    

    Syntax:LoadFile filename [filename] ...
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_so
    

    

    
    The LoadFile directive links in the named object files or
    libraries when the server is started or restarted; this is used
    to load additional code which may be required for some module
    to work. Filename is either an absolute path or
    relative to ServerRoot.
    

    
    For example:
    

    
    LoadFile "libexec/libxmlparse.so"

    LoadModule Directive
    

    

    Description:Links in the object file or library, and adds to the list
of active modules
    

    Syntax:LoadModule module filename
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_so
    

    
    
    The LoadModule directive links in the object file or library
    filename and adds the module structure named
    module to the list of active modules. Module
    is the name of the external variable of type
    module in the file, and is listed as the Module Identifier
    in the module documentation.
    

    
    For example:
    

    
    LoadModule status_module "modules/mod_status.so"
    


    
    loads the named module from the modules subdirectory of the
    ServerRoot.

mod_remoteip - Serveur HTTP Apache Version 2.4

    Serveur HTTP Apache Version 2.4

    Module Apache mod_remoteip
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Remplace l'adresse IP du client
pour la requête par l'adresse IP présentée par un mandataire ou un
répartiteur de charge via les en-têtes de la requête.

    

    Statut:Base
    

    Identificateur de Module:remoteip_module
    

    Fichier Source:mod_remoteip.c
    

    Sommaire
    

    
    Ce module permet de traiter le client qui a initié la
    requête en tant que client original du point de vue de httpd à
    des fins d'autorisation et de connexion, même si ce client se
    trouve derrière un répartiteur de charge, un serveur frontal, ou un
    serveur mandataire.
    

    
    Le module remplace l'adresse IP du client
    pour la connexion par l'adresse IP indiquée dans
    l'en-tête de requête configuré via la directive
    RemoteIPHeader.
    

    
    Ce module implémente aussi la partie serveur du protocole PROXY
    de HAProxy via la directive RemoteIPProxyProtocol.
    

    
    Une fois sa valeur modifiée comme indiqué, cette adresse IP client est
    utilisée pour la fonctionnalité Require ip de mod_authz_host ;
    elle est aussi affichée par mod_status, et enregistrée via
    les chaînes de formatage %a des modules
    mod_log_config et core.  L'adresse IP
    client sous-jacente de la connexion est enregistrée via la chaîne de
    formatage %{c}a.  
    

    
    Il est essentiel de n'activer cette
    fonctionnalité que pour les requêtes en provenance des serveurs
    intermédiaires (mandataires, etc...) auxquels le serveur peut faire
    confiance, car il est trivial pour le client distant d'usurper
    l'identité d'un autre client.
    

    


    top
    

    

    Traitement des adresses distantes
    

    
    Par défaut, Apache identifie le client via la valeur client_ip de la
    connexion, et de cette valeur découlent les valeurs remote_host et
    remote_logname de la connexion. Ces champs jouent un rôle
    dans l'authentification, l'autorisation et la journalisation, ainsi que
    dans d'autres traitements effectués par d'autres modules
    chargeables.
    

    
    mod_remoteip remplace l'adresse IP client de la connexion par l'adresse IP client
    indiquée par exemple par un mandataire ou un répartiteur de charge
    pour toute la durée de la requête. Un répartiteur de charge pourra ainsi
    établir une connexion keepalive de longue durée avec le serveur, chaque
    requête conservant alors l'adresse IP client correcte bien que l'adresse IP
    client sous-jacente du répartiteur de charge reste inchangée.
    

    
    Lorsque la valeur de l'en-tête comporte plusieurs adresses IP
    client séparées par des virgules, celles-ci sont traitées de la
    droite vers la gauche. Le traitement s'arrête lorsque l'adresse IP
    client courante n'est pas digne de confiance pour présenter
    l'adresse IP précédente. Le champ d'en-tête est alors mis à jour de
    façon à ne contenir que cette liste d'adresses non confirmées, ou
    bien, si toutes les adresses IP sont dignes de confiance, cet
    en-tête est tout bonnement supprimé de la requête.
    

    
    Lors du remplacement de l'adresse IP client, le module stocke
    la liste des hôtes intermédiaires dans un mémo
    remoteip-proxy-ip-list, que l'on peut faire enregistrer par
    mod_log_config en utilisant le symbole de format
    %{remoteip-proxy-ip-list}n. Si l'administrateur doit
    stocker ceci dans un en-tête additionnel, la même valeur peut aussi
    être enregistrée sous la forme d'un en-tête en utilisant la
    directive RemoteIPProxiesHeader.
    

    
    Adresses IPv4 converties au format IPv6
    
    Avec httpd, d'une manière générale, toute adresse IPv4 convertie au
    format IPv6 est enregistrée sous sa forme IPv4.
    

    
    Adresses internes (privées)
    
    Tous les blocs d'adresses internes 10/8, 172.16/12, 192.168/16,
    169.254/16 and 127/8 (ainsi que les adresses IPv6 en dehors du bloc
    public 2000::/3 block) ne sont évaluées par mod_remoteip que lorsque
    des mandataires internes (intranet)
    RemoteIPInternalProxy sont enregistrés.

    Directive RemoteIPHeader
    

    

    Description:Définit le champ d'en-tête qui contiendra les adresses IP
du client
    

    Syntaxe:RemoteIPHeader en-tête
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_remoteip
    

    
    
    La directive RemoteIPHeader indique à
    mod_remoteip de traiter la valeur de
    l'en-tête spécifié comme l'adresse IP du client, ou comme
    une liste d'adresses IP clients intermédiaires, en fonction de la
    configuration des directives
    RemoteIPInternalProxy et
    RemoteIPTrustedProxy. Si ces
    deux dernières directives ne sont pas utilisées,
    mod_remoteip traitera tout hôte présentant une adresse non
    interne dans l'en-tête RemoteIPHeader comme hôte de confiance.
    
    
    
    Si ces deux dernières
    directives ne sont pas utilisées, mod_remoteip
    traitera tout hôte présentant une adresse non interne
    dans l'en-tête RemoteIPHeader comme hôte de
    confiance.
    

    
    Exemple à usage interne (répartiteur de
    charge)
    RemoteIPHeader X-Client-IP
    

    

    
    Exemple dans le cas d'un mandataire
    RemoteIPHeader X-Forwarded-For
    

    


    

    top
    

    Directive RemoteIPInternalProxy
    

    

    Description:Déclare les adresses IP intranet clients comme dignes de
confiance pour présenter la valeur RemoteIPHeader
    

    Syntaxe:RemoteIPInternalProxy
ip-mandataire|ip-mandataire/sous-réseau|nom-hôte ...
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_remoteip
    

    
    
    La directive RemoteIPInternalProxy permet
    d'ajouter une ou plusieurs adresses (ou blocs d'adresses) auxquelles
    on peut faire confiance pour présenter une valeur RemoteIPHeader
    valide de l'adresse IP du client. A la différence de la directive
    RemoteIPTrustedProxy, toute adresse IP
    présentée dans cet en-tête, y comprises les adresses intranet
    privées, sont considérées comme dignes de confiance lorsqu'elles
    sont indiquées par ces mandataires.
    

    
    Exemple à usage interne (répartiteur de
    charge)
    RemoteIPHeader X-Client-IP
RemoteIPInternalProxy 10.0.2.0/24
RemoteIPInternalProxy gateway.localdomain

    Directive RemoteIPInternalProxyList
    

    

    Description:Déclare les adresses IP intranet clients comme dignes de
confiance pour présenter la valeur RemoteIPHeader
    

    Syntaxe:RemoteIPInternalProxyList nom-fichier
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_remoteip
    

    
    
    La directive RemoteIPInternalProxyList
    permet de spécifier un fichier parcouru au démarrage du serveur pour
    construire une liste d'adresses (ou blocs d'adresses), auxquelles
    on peut faire confiance pour présenter une valeur RemoteIPHeader
    valide de l'adresse IP du client.
    

    
    Le caractère '#' indique une ligne de commentaires,
    sinon, toutes les lignes séparées par un caractère nouvelle
    ligne ou
    tous les éléments d'une ligne séparés par un espace sont traités de
    la même façon qu'avec la directive
    RemoteIPInternalProxy.
    

    
    Exemple à usage interne (répartiteur de
    charge)
    RemoteIPHeader X-Client-IP
RemoteIPInternalProxyList conf/trusted-proxies.lst
    

    

    
    contenu de conf/mandataires-de-confiance.lst

    Syntaxe:RemoteIPProxiesHeader Nom_en-tête
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_remoteip
    

    
    
    La directive RemoteIPProxiesHeader permet
    de spécifier l'en-tête dans lequel mod_remoteip va
    collecter une liste de toutes les adresses IP clients intermédiaires
    auxquelles on pourra faire confiance pour résoudre l'adresse IP
    client de la requête. Notez que les adresses intermédiaires
    RemoteIPTrustedProxy sont enregistrées dans
    cet en-tête, alors que toute adresse intermédiaire
    RemoteIPInternalProxy est omise.
    

    
    Exemple
    RemoteIPHeader X-Forwarded-For
RemoteIPProxiesHeader X-Forwarded-By

    Syntaxe:RemoteIPProxyProtocol On|Off
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_remoteip
    

    Compatibilité:Disponible à partir de la version 2.4.31 du serveur HTTP Apache
    

    
    
    La directive RemoteIPProxyProtocol permet
    d'activer ou de désactiver la prise en compte et la gestion de l'en-tête de
    connexion du protocole PROXY. Si elle est définie à On, la
    demande du client doit envoyer l'en-tête approprié pour chaque
    nouvelle connexion, sinon cette dernière sera fermée à moins qu'il ne fasse
    partie de la liste, définie via la directive RemoteIPProxyProtocolDisableHosts, des
    hôtes pour lesquels le protocole PROXY est désactivé.
    

    
    Bien que cette directive peut être définie au niveau de n'importe quel
    serveur virtuel, il est important de garder à l'esprit que, étant donné que
    le protocole PROXY est basé sur la connexion et agnostique quant au
    protocle, son activation/désactivation est basée sur le couple adresse
    IP/port. Cela signifie que si plusieurs serveurs virtuels à base de nom sont
    configurés avec le même couple adresse IP/port, et si vous activez le
    protocole PROXY pour l'un d'entre eux, il le sera aussi pour tous les autres
    (avec le même couple adresse IP/port). Cela signifie aussi que si vous
    tentez d'activer le protocole PROXY pour un serveur virtuel et de le
    désactiver pour un autre, cela ne marchera pas ; dans ce dernier cas, la
    dernière directive l'emporte sur les autres et une notification sera
    enregistrée dans le journal pour indiquer les réglages qui ont été annulés.

    La directive RemoteIPProxyProtocol permet de
    contrôler la prise en compte de l'en-tête de connexion du protocole PROXY.
    Il est parfois souhaitable d'exiger pour certains clients la
    présence de l'en-tête PROXY, mais aussi de permettre aux autres clients de
    se connecter sans ce dernier. Cette directive permet à l'administrateur du
    serveur d'autoriser cette possibilité à un hôte isolé ou à une gamme d'hôtes
    au format CIDR.

    Beschreibung:Dieses Modul ermöglicht die Ausführung von CGI-Skripten
  in Abhängigkeit von Medientypen und Anfragemethoden.
    

    Status:Basis
    

    Modulbezeichner:actions_module
    

    Quelltext-Datei:mod_actions.c
    

    Zusammenfassung
    

    
    Das Modul besitzt zwei Direktiven. Die Direktive Action erlaubt die Ausführung von 
      CGI-Skripten immer dann, wenn eine Anfrage zu einem bestimmten MIME-Type erfolgt. Die Direktive Script erlaubt die Ausführung von
      CGI-Skripten abhängig von einer bestimmten Methode, die in der
      Anfrage verwendet wird. Dies macht es deutlich einfacher, Skripte
      auszuführen, die Dateien verarbeiten.

    Action-Direktive
    

    

    Beschreibung:Aktiviert ein CGI-Skript für einen bestimmten Handler oder
  Content-Type
    

    Syntax:Action Aktionsart CGI-Skript [virtual]
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis, .htaccess
    

    AllowOverride:FileInfo
    

    Status:Basis
    

    Modul:mod_actions
    

    Kompatibilität:Der Schalter virtual und die Übergabe des 
  Handlers wurden in Apache 2.1 eingeführt.
    

    
    
    Die Direktive fügt eine Aktion hinzu, welche das
      CGI-Skript aktiviert, sobald die Aktionsart durch
      eine Anfrage ausgelöst wird. CGI-Skript ist der URL-Pfad
      zu einer Ressource, die unter Verwendung von ScriptAlias oder AddHandler als CGI-Skript gekennzeichnet
      wurde. Die Aktionsart kann entweder ein Handler oder ein MIME-Type sein. Die URL und
      den Dateipfad des angeforderten Dokuments in den 
      Standard-CGI-Umgebungsvariablen PATH_INFO und
      PATH_TRANSLATED übergeben. Der für die jeweilige 
      Anfrage verwendete Handler wird in der Umgebungsvariablen
      REDIRECT_HANDLER übergeben.
    

    
    Beispiele
    
      # Anfragen für Dateien eines bestimmten MIME-Types:
    
      Action image/gif /cgi-bin/images.cgi
    
      
    
      # Dateien einer bestimmten Dateiendung
    
      AddHandler my-file-type .xyz
    
      Action my-file-type /cgi-bin/program.cgi
    
    
    

    
    Im ersten Beispiel werden Anfragen für Dateien mit dem MIME-Type
      image/gif von dem angegebenen CGI-Skript
      /cgi-bin/images.cgi bearbeitet.
    

    
    Im zweiten Beispiel werden Anfragen für Dateien mit der Dateiendung
      .xyz von dem angegebenen CGI-Skript 
      /cgi-bin/program.cgi bearbeitet.
    

    
    Der optionale Schalter virtual deaktiviert die Prüfung
      auf Existenz der angeforderten Datei. Dies ist beispielsweise 
      nützlich, wenn Sie die Direktive Action in 
      Verbindung mit virtuellen Adressräumen verwenden möchten.
     

    
    Beispiel
    
      <Location /news>
    
      
        SetHandler news-handler
    
        Action news-handler /cgi-bin/news.cgi virtual
    
          
      </Location>

    Script-Direktive
    

    

    Beschreibung:Aktiviert ein CGI-Skript für eine bestimmte 
  Anfragemethode.
    

    Syntax:Script Methode CGI-Skript
    

    Kontext:Serverkonfiguration, Virtual Host, Verzeichnis
    

    Status:Basis
    

    Modul:mod_actions
    

    
  
    Die Direktive fügt eine Aktion hinzu, welche das
    CGI-Skript aktiviert, wenn eine Datei unter der Verwendung der
    Methode Methode angefordert wird. CGI-Skript ist der 
    URL-Pfad zu einer Ressource, die unter Verwendung von ScriptAlias oder AddHandler als CGI-Skript gekennzeichnet
    wurde. Die URL und der Dateipfad des angeforderten Dokuments werden in den
    Standard-CGI-Umgebungsvariablen PATH_INFO und
    PATH_TRANSLATED übergeben.
    

    
    
      Der Methodenname kann frei gewählt werden. Bei Methodennamen
      wird zwischen Groß- und Kleinschreibung unterschieden, so
      dass Script PUT und Script put zu vollkommen
      unterschiedlichen Ergebnissen führen.
    
    

    
    Beachten Sie, dass der Script-Befehl nur
      Voreinstellungen für Aktionen definiert. Wird ein CGI-Skript
      - oder eine andere Ressource, die in der Lage ist, die angeforderte 
      Methode intern zu bearbeiten - aufgerufen, so wird diese(s) verwendet.
      Beachten Sie auch, dass Script mit der Methode
      GET nur dann aufgerufen wird, wenn Query-Argumente vorhanden
      sind (z.B. foo.html?hi). Andernfalls wird die Anfrage normal
      bearbeitet.
    

    
    Beispiele
    
      # Für <ISINDEX>-ähnliches Suchen
    
      Script GET /cgi-bin/search
    
      
    
      # Ein CGI-PUT-Handler
    
      Script PUT /~bob/put.cgi

    Serveur HTTP Apache Version 2.4

    Module Apache mod_proxy_wstunnel
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Module pour mod_proxy supportant les
websockets
    

    Statut:Extension
    

    Identificateur de Module:proxy_wstunnel_module
    

    Fichier Source:mod_proxy_wstunnel.c
    

    Compatibilité:Disponible à partir de la version 2.4.5 du serveur HTTP
Apache
    

    Sommaire
    

    
    Pour utiliser ce module, mod_proxy doit être
    chargé. Il fournit le support du tunnelling pour les connexions
    websocket vers un serveur websockets d'arrière-plan. La connexion
    est automatiquement promue en connexion websocket :
    

    
    Réponse HTTP
    Upgrade: WebSocket
Connection: Upgrade
    

    	


    Le mandatement des requêtes vers un serveur websockets comme
echo.websocket.org peut être configuré via la directive ProxyPass :
    
    
    ProxyPass "/ws2/"  "ws://echo.websocket.org/"
ProxyPass "/wss2/" "wss://echo.websocket.org/"
    



    Il est possible de mandater les websockets et HTTP en même temps, avec un jeu
spécifique d'URLs pour les websockets, en définissant la directive ProxyPass concernant les
websockets avant celle concernant HTTP :
    

    ProxyPassMatch ^/(myApp/ws)$  ws://backend.example.com:9080/$1
ProxyPass / http://backend.example.com:9080/
    



    Il est possible de mandater les websockets et HTTP en même temps, lorsque
les URLs websockets ne concernent pas uniquement les websockets ou ne sont pas
connues à l'avance, en utilisant la directive RewriteRule pour configurer le mandatement des
websockets :
    

    ProxyPass / http://example.com:9080/
RewriteEngine on
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "ws://example.com:9080/$1" [P,L]
    



    La répartition de charge entre plusieurs serveurs d'arrière-plan peut être
configurée via le module mod_proxy_balancer.
    


    En fait, ce module permet d'accepter d'autres protocoles ; vous pouvez à cet
effet utiliser le paramètre upgrade de la directive ProxyPass. La valeur NONE
signifie que vous court-circuitez la consultation de l'en-tête, mais que vous
autorisez quand-même WebSocket. La valeur ANY signifie que Upgrade
va lire les en-têtes de la requête et les utilisera dans l'en-tête
Upgrade de la réponse.

    Directive ProxyWebsocketFallbackToProxyHttp
    

    

    Description:Demande à ce module de laisser mod_proxy_http
gérer la requête
    

    Syntaxe:ProxyWebsocketFallbackToProxyHttp On|Off
    

    Défaut:ProxyWebsocketFallbackToProxyHttp On
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy_wstunnel
    

    Compatibilité:Disponible à partir de la version 2.4.48 du serveur HTTP Apache
    

    
    
    Depuis la version 2.4.47 de httpd, mod_proxy_http peut
    gérer le tunneling et la mise à jour via les WebSockets en accord avec la
    RFC 7230 ; cette directive permet de définir si, pour ces actions,
    mod_proxy_wstunnel doit passer la main à
    mod_proxy_http, ce qui est le cas par défaut.
    
    
    Définir cette directive à Off revient à laisser
    mod_proxy_wstunnel gérer les requêtes WebSocket, comme avec
    les versions 2.4.46 et antérieures de httpd.

    The Require Directives
    

    
    Les directives Require d'Apache permettent,
    au cours de la phase d'autorisation, de s'assurer qu'un utilisateur
    est bien autorisé à accéder à une
    ressource.  mod_authz_user ajoute
    les types d'autorisation user et valid-user.
    
    

    
    A partir de la version 2.4.8, les directives require DBM
    supportent les expressions.
    


    Require user
    

    
    Cette directive permet de spécifier une liste d'utilisateurs
    autorisés à accéder à la ressource.
    

    
    Require user john paul george ringo
    





    Require valid-user
    

    
    Lorsque cette directive est définie, tout utilisateur qui s'est
    authentifié avec succès aura l'autorisation d'accès à la ressource.
    

    
    Require valid-user

    Description:Comprime le contenu avant de le servir au
client
    

    Statut:Extension
    

    Identificateur de Module:deflate_module
    

    Fichier Source:mod_deflate.c
    

    Sommaire
    

    
    Le module mod_deflate implémente le filtre de
    sortie DEFLATE qui permet de comprimer la sortie de
    votre serveur avant de l'envoyer au client sur le réseau.
    

    


    top
    

    

    Codages supportés
    
  
    Le seul codage supporté est gzip afin d'assurer une complète
  compatibilité avec les anciens navigateurs. Le codage deflate
  n'est donc pas supporté ; voir à ce sujet la documentation de zlib pour une
  explication détaillée.
  
    

    top
    

    

    Exemples de configurations
    
    
    Compression et TLS
    
        
    Certaines applications web sont vulnérables aux attaques
	visant le vol d'information lorsqu'une connexion TLS transmet
	des données compressées par deflate. Pour plus de détails,
	étudiez les attaques de la famille "BREACH".
    
    
    
    
    Voici une configuration simple qui comprime les contenus à base
    de texte courants.
    

    
    Ne comprime que certains types de documents
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
    

    


    top
    

    

    Activation de la compression
    

    
    Compression et TLS
    
        
    Certaines applications web sont vulnérables aux attaques pour
	vol d'information lorsque la connexion TLS transmet des données
	compressées par deflate. Pour plus d'informations, voir en
	détails la famille d'attaques de type "BREACH".
    
    
    

    
    Compression de la sortie
    
      
    La compression est implémentée par le filtre DEFLATE. La
      directive suivante active la compression des documents dans le
      conteneur où elle est placée :
    

      
    SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI "\.(?:gif|jpe?g|png)$" no-gzip
    


      
    Si vous voulez limiter la compression à certains types MIME
      particuliers, vous pouvez utiliser la directive AddOutputFilterByType. Voici un exemple
      où la compression n'est activée que pour les fichiers html de la
      documentation d'Apache :
    

      
    <Directory "/your-server-root/manual">
    AddOutputFilterByType DEFLATE text/html
</Directory>
    


      
    Note
    
        Le filtre DEFLATE est toujours inséré après les
	filtres RESOURCE comme PHP ou SSI. Il n'affecte jamais les
	sous-requêtes internes.
      
    
      
    Note
    
        La variable d'environnement force-gzip, définie à
	l'aide de la directive SetEnv, permet d'ignorer la
	configuration de votre navigateur quant aux codages acceptés, et
	d'envoyer sans condition une sortie comprimée.
      
    

    
    
    Décompression de la sortie
    
      
    Le module mod_deflate fournit aussi un filtre
      permettant de décomprimer un corps de réponse comprimé par gzip.
      Pour activer cette fonctionnalité, vous devez insérer le filtre
      INFLATE dans la chaîne de filtrage en sortie via la
      directive SetOutputFilter ou
      AddOutputFilter, comme
      dans l'exemple suivant :
    

      
    <Location "/dav-area">
    ProxyPass "http://example.com/"
    SetOutputFilter INFLATE
</Location>
    


      
    Dans cet exemple, les sorties comprimées par gzip en
      provenance de example.com seront décomprimées afin de pouvoir
      être éventuellement traitées par d'autres filtres.
      
    

    
    
    Décompression de l'entrée
    
      
    Le module mod_deflate fournit également un filtre
      permettant de décomprimer un corps de requête comprimé par gzip.
      Pour activer cette fonctionnalité, vous devez insérer le filtre
      DEFLATE dans la chaîne de filtrage en entrée via la
      directive SetInputFilter ou
      AddInputFilter, comme
      dans l'exemple suivant :
    

      
    <Location "/dav-area">
    SetInputFilter DEFLATE
</Location>
    


      
    Désormais, si une requête contient un en-tête
      Content-Encoding: gzip, son corps sera
      automatiquement décomprimé. Peu de navigateurs sont actuellement
      en mesure de comprimer les corps de requêtes. Cependant,
      certaines applications spécialisées supportent les requêtes
      comprimées, comme par exemple certains clients WebDAV.
    

      
    Note à propos de l'en-tête
      Content-Length
    
        
    Si vous évaluez vous-même la taille du corps de requête,
	ne faites pas confiance à l'en-tête
	Content-Length! L'en-tête
	Content-Length indique la longueur des données en provenance du
	client, et non la quantité d'octets que représente le
	flux de données décompressé.
    
      
    
    

    top
    

    

    Prise en compte des serveurs mandataires
    

    
    Le module mod_deflate envoie un en-tête de
    réponse HTTP Vary: Accept-Encoding pour avertir les
    mandataires qu'une réponse enregistrée dans le cache ne doit être
    envoyée qu'aux clients qui ont envoyé l'en-tête de requête
    Accept-Encoding approprié. Ceci permet d'éviter l'envoi
    d'un contenu comprimé à un client qui ne sera pas en mesure
    de l'interpréter.
    

    
    Si vous avez défini des exclusions spécifiques dépendant, par
    exemple, de l'en-tête User-Agent, vous devez
    ajouter manuellement des données à l'en-tête Vary afin
    d'informer les mandataires des restrictions supplémentaires. Par
    exemple, dans la configuration classique où l'addition du filtre
    DEFLATE dépend du contenu de l'en-tête
    User-Agent, vous devez spécifier :
    

    
    Header append Vary User-Agent
    


    
    Si votre décision de comprimer le contenu dépend d'autres
    informations que celles contenues dans les en-têtes de la requête
    (par exemple la version HTTP), vous devez attribuer à l'en-tête
    Vary la valeur *, ce qui permet d'empêcher
    les mandataires compatibles de tout mettre en cache.
    

    
    Exemple
    Header set Vary *
    

    

    top
    

    

    Servir du contenu précompressé
    

    
    Comme mod_deflate recompresse le contenu demandé à
    chaque requête, il est possible de gagner en performances en précompressant
    ce contenu, et en forçant mod_deflate à servir ce contenu
    précompressé sans avoir à le recompresser à chaque requête.  Pour ce faire,
    utilisez une configuration du style :
    

    
    <IfModule mod_headers.c>
    # Servir des fichiers CSS et JS compressés avec gzip, s'ils existent, et
    # si le client accepte gzip.
    RewriteCond "%{HTTP:Accept-encoding}" "gzip"
    RewriteCond "%{REQUEST_FILENAME}\.gz" -s
    RewriteRule "^(.*)\.(css|js)"         "$1\.$2\.gz" [QSA]

    # Servir des types de contenus corrects, et empêcher mod_deflate
    # d'effectuer un double gzip.
    RewriteRule "\.css\.gz$" "-" [T=text/css,E=no-gzip:1]
    RewriteRule "\.js\.gz$"  "-" [T=text/javascript,E=no-gzip:1]


    <FilesMatch "(\.js\.gz|\.css\.gz)$">

fois
    

    Syntaxe:DeflateBufferSize valeur
    

    Défaut:DeflateBufferSize 8096

    Statut:Extension
    

    Module:mod_deflate
    

    
    
    La directive DeflateBufferSize permet de
    spécifier la taille en octets du fragment que zlib devra comprimer
    en une seule fois. Si la taille de la réponse compressée est supérieure à
    celle spécifiée par cette directive, httpd passera à un mode d'encodage
    fragmenté (l'en-tête HTTP Transfer-Encoding prend la valeur
    Chunked), ceci ayant comme effet de bord de ne définir aucun
    en-tête HTTP Content-Length. Il est important de connaître ce
    comportement, particulièrement lorsque httpd travaille derrière des
    mandataires inverses avec mise en cache, ou lorsque httpd est configuré pour
    utiliser mod_cache et mod_cache_disk car
    les réponses HTTP sans en-tête Content-Length peuvent ne pas
    être mises en cache.

    La directive DeflateCompressionLevel
    permet de spécifier le niveau de compression à utiliser ; plus
    grande est la valeur, meilleure sera la compression, mais plus grand
    sera aussi le temps CPU nécessaire pour effectuer le
    traitement.
    
    
    La valeur doit être comprise entre 1 (compression minimale) et 9
    (compression maximale).

    Directive DeflateFilterNote
    

    

    Description:Enregistre le taux de compression sous la forme d'une note

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_deflate
    

    
    
    La directive DeflateFilterNote permet de
    spécifier qu'une note à propos du taux de compression doit être
    attachée à la requête. Le nom de la note est passé sous la forme
    d'un argument de la directive. Vous pouvez utiliser cette note à des
    fins statistiques en enregistrant sa valeur dans votre journal des accès.
    

    
    Exemple
          DeflateFilterNote ratio
    
      LogFormat '"%r" %b (%{ratio}n) "%{User-agent}i"' deflate
      CustomLog "logs/deflate_log" deflate
    

    

    
    Pour extraire des informations plus précises de vos journaux,
    vous pouvez utiliser l'argument type pour spécifier le
    type de données de la note enregistrée dans le journal.
    type peut prendre une des valeurs suivantes :
    

    
    
      
    Input
    
      
    Enregistre dans la note la taille en octets du flux en entrée
      du filtre.
    

      
    Output
    
      
    Enregistre dans la note la taille en octets du flux en sortie
      du filtre.
    

      
    Ratio
    
      
    Enregistre le taux de compression (sortie/entrée *
      100) dans la note. Il s'agit de la valeur par défaut si
      l'argument type est omis.
    
    
    

    
    Vous pouvez donc configurer votre journalisation de la manière
    suivante :
    

    
    Journalisation détaillée
    DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio

LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
CustomLog "logs/deflate_log" deflate

mod_systemd - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Apache Module mod_systemd
    

    

    Available Languages:  en  |

    Description:Provides better support for systemd integration
    

    Status:Extension
    

    Module Identifier:systemd_module
    

    Source File:mod_systemd.c
    

    Compatibility:Available in Apache 2.4.42 and later
    

    Summary
    

    
    This module provides support for systemd integration. It allows
    httpd to be used in a service with the systemd
    Type=notify (see systemd.service(5)
    for more information).  The module is activated if loaded.
    

    
    Example of systemd service unit (more settings are probably needed for production systems)
    [Unit]
Description=The Apache HTTP Server
After=network.target

[Service]
Type=notify
ExecStart=/usr/local/apache2/bin/httpd -D FOREGROUND -k start
ExecReload=/usr/local/apache2/bin/httpd -k graceful
KillMode=mixed

[Install]
WantedBy=multi-user.target
    

   
    Special attention should be given to how ExecStop
   and/or KillMode are configured for the service.  If
   configured, an ExecStop command should be a
   synchronous operation which itself exits when the daemon
   has terminated.  Running httpd -k stop
   asynchronously initiates daemon termination, so does not
   satisfy this condition.  The example above uses
   KillMode=mixed so that systemd sends
   SIGTERM to signal the parent process (and only the
   parent) to shut down.  The entire process group is then sent
   SIGKILL after TimeoutStopSec elapses, if
   any processes are still running.  See systemd.kill(5)
   for more information.
    
    
   
    This module does not provide support for Systemd socket activation.
    

    
    ExtendedStatus is
    enabled by default if the module is loaded.  If ExtendedStatus is not disabled in
    the configuration, run-time load and request statistics are made
    available in the systemctl status output.

    Sommaire
    


    
    Il arrive que des requêtes pour des documents ne puissent pas
    être traitées par le serveur Apache de base à cause d'une erreur
    de frappe ou de casse. Ce module permet de traiter ce
    problème en essayant de trouver un document correspondant, même
    lorsque tous les autres modules y ont renoncé. Sa méthode de travail
    consiste à comparer chaque nom de document du répertoire demandé
    avec le document de la requête sans tenir compte de la
    casse, et en acceptant jusqu'à une erreur
    (insertion, omission, inversion de caractère ou caractère
    erroné). Une liste de tous les documents qui correspondent est alors
    élaborée en utilisant cette stratégie. Ce module traite aussi les
    erreurs dans les extensions de fichiers.
    

    
    Si après le parcours du répertoire,
    

    
      
      
    • aucun document correspondant n'a été trouvé, Apache procèdera
      normalement et renverra une erreur (404 - document not found).
      • 

      
    • un seul document correspondant pratiquement à la requête a
      été trouvé, celui-ci est renvoyé sous la forme d'une réponse de
      redirection (301 - Moved Permanently).
      • 

      
    • plusieurs documents pouvant correspondre ont été trouvés, une
      liste des documents est envoyée au client afin que ce dernier
      puisse sélectionner le document correct (300 - Multiple
      Choices).

    Lorsqu'elle est définie, cette directive étend le processus de correction
    orthographique à l'extension des noms de fichiers. Par exemple, un fichier
    de nom foo.gif sera pris en compte par une requête pour
    foo ou foo.jpg. Ceci peut s'avérer
    particulièrement utile en conjonction avec les MultiViews.

    corrections éventuelles ne seront effectuées que si la directive CheckBasenameMatch est elle aussi définie.

    Module:mod_speling
    

    
    
    Cette directive permet d'activer ou de désactiver le module de
    correction. Lorsqu'il est activé, rappelez-vous que :
    

    
      
      
    • le parcours du répertoire nécessaire à la correction aura un
      impact sur les performances du serveur lorsque de nombreuses
      corrections devront être effectuées au même moment.
      • 

      
    • l'arborescence ne doit pas contenir de documents
      sensibles qui pourraient être considérés par erreur comme
      correspondant à la requête.
      • 

      
    • le module ne corrige pas les noms d'utilisateur mal
      orthographiés (comme dans
      http://mon.serveur/~apahce/), mais seulement les noms
      de fichiers ou de répertoires.
      • 

      
    • les corrections s'appliquent strictement aux fichiers
      existants, si bien qu'une requête pour <Location
      /status> pour être traitée de manière incorrecte comme
      une requête pour le fichier négocié "/stats.html".
      • 
    
    

    
    
    mod_speling ne doit pas être activé pour des répertoires
    où DAV l'est aussi, car il va essayer de
    "corriger" les noms des ressources nouvellement créées en fonction des noms
    de fichiers existants ; par exemple, lors du chargement d'un nouveau
    document doc43.html, il est possible qu'il redirige vers un
    document existant doc34.html, ce qui ne correspond pas à ce que
    l'on souhaite.

    Summary
    

    
    Warning
    
      
    The session modules make use of HTTP cookies, and as such can fall
      victim to Cross Site Scripting attacks, or expose potentially private
      information to clients. Please ensure that the relevant risks have
      been taken into account before enabling the session functionality on
      your server.
    
    
    

    
    This module provides support for a server wide per user session
    interface. Sessions can be used for keeping track of whether a user
    has been logged in, or for other per user information that should
    be kept available across requests.
    

    
    Sessions may be stored on the server, or may be stored on the
    browser. Sessions may also be optionally encrypted for added security.
    These features are divided into several modules in addition to
    mod_session; mod_session_crypto,
    mod_session_cookie and mod_session_dbd.
    Depending on the server requirements, load the appropriate modules
    into the server (either statically at compile time or dynamically
    via the LoadModule directive).
    

    
    Sessions may be manipulated from other modules that depend on the
    session, or the session may be read from and written to using
    environment variables and HTTP headers, as appropriate.

    What is a session?
    
      
    At the core of the session interface is a table of key and value pairs
      that are made accessible across browser requests. These pairs can be set
      to any valid string, as needed by the application making use of the
      session.
    

      
    The "session" is a application/x-www-form-urlencoded
      string containing these key value pairs, as defined by the
      HTML specification.
    

      
    The session can optionally be encrypted and base64 encoded before
      being written to the storage mechanism, as defined by the
      administrator.
    

    
    top
    

    

    Who can use a session?
    
      
    The session interface is primarily developed for the use by other
      server modules, such as mod_auth_form, however CGI
      based applications can optionally be granted access to the contents
      of the session via the HTTP_SESSION environment variable. Sessions
      have the option to be modified and/or updated by inserting an HTTP
      response header containing the new session parameters.
    

    
    top
    

    

    Keeping sessions on the server
    
      
    Apache can be configured to keep track of per user sessions stored
      on a particular server or group of servers. This functionality is
      similar to the sessions available in typical application servers.
    

      
    If configured, sessions are tracked through the use of a session ID that
      is stored inside a cookie, or extracted from the parameters embedded
      within the URL query string, as found in a typical GET request.
    

      
    As the contents of the session are stored exclusively on the server,
      there is an expectation of privacy of the contents of the session. This
      does have performance and resource implications should a large number
      of sessions be present, or where a large number of webservers have to
      share sessions with one another.
    

      
    The mod_session_dbd module allows the storage of user
      sessions within a SQL database via mod_dbd.
    

    
    top
    

    

    Keeping sessions on the browser
    
      
    In high traffic environments where keeping track of a session on a
      server is too resource intensive or inconvenient, the option exists to store
      the contents of the session within a cookie on the client browser instead.
    

      
    This has the advantage that minimal resources are required on the
      server to keep track of sessions, and multiple servers within a server
      farm have no need to share session information.
    

      
    The contents of the session however are exposed to the client, with a
      corresponding risk of a loss of privacy. The
      mod_session_crypto module can be configured to encrypt the
      contents of the session before writing the session to the client.
    

      
    The mod_session_cookie allows the storage of user
      sessions on the browser within an HTTP cookie.
    

    
    top
    

    

    Basic Examples
    

      
    Creating a session is as simple as turning the session on, and deciding
      where the session will be stored. In this example, the session will be
      stored on the browser, in a cookie called session.
    

      
    Browser based session
    Session On
SessionCookieName session path=/
    

    

      
    The session is not useful unless it can be written to or read from. The
      following example shows how values can be injected into the session through
      the use of a predetermined HTTP response header called
      X-Replace-Session.
    

      
    Writing to a session
    Session On
SessionCookieName session path=/
SessionHeader X-Replace-Session
    

    

      
    The header should contain name value pairs expressed in the same format
      as a query string in a URL, as in the example below. Setting a key to the
      empty string has the effect of removing that key from the session.
    

      
    CGI to write to a session
    #!/bin/bash
echo "Content-Type: text/plain"
echo "X-Replace-Session: key1=foo&key2=&key3=bar"
echo
env
    

    

      
    If configured, the session can be read back from the HTTP_SESSION
      environment variable. By default, the session is kept private, so this
      has to be explicitly turned on with the
      SessionEnv directive.
    

      
    Read from a session
    Session On
SessionEnv On
SessionCookieName session path=/
SessionHeader X-Replace-Session
    

    

      
    Once read, the CGI variable HTTP_SESSION should contain
      the value key1=foo&key3=bar.
    

    
    top
    

    

    Session Privacy
    

      
    Using the "show cookies" feature of your browser, you would have seen
      a clear text representation of the session. This could potentially be a
      problem should the end user need to be kept unaware of the contents of
      the session, or where a third party could gain unauthorised access to the
      data within the session.
    

      
    The contents of the session can be optionally encrypted before being
      placed on the browser using the mod_session_crypto
      module.
    

      
    Browser based encrypted session
    Session On
SessionCryptoPassphrase secret
SessionCookieName session path=/
    

    

      
    The session will be automatically decrypted on load, and encrypted on
      save by Apache, the underlying application using the session need have
      no knowledge that encryption is taking place.
    

      
    Sessions stored on the server rather than on the browser can also be
      encrypted as needed, offering privacy where potentially sensitive
      information is being shared between webservers in a server farm using
      the mod_session_dbd module.
    

    
    top
    

    

    Cookie Privacy
    

      
    The HTTP cookie mechanism also offers privacy features, such as the
      ability to restrict cookie transport to SSL protected pages only, or
      to prevent browser based javascript from gaining access to the contents
      of the cookie.
    

      
    Warning
    
      
    Some of the HTTP cookie privacy features are either non-standard, or
      are not implemented consistently across browsers. The session modules
      allow you to set cookie parameters, but it makes no guarantee that privacy
      will be respected by the browser. If security is a concern, use the
      mod_session_crypto to encrypt the contents of the session,
      or store the session on the server using the mod_session_dbd
      module.
    
      
    

      
    Standard cookie parameters can be specified after the name of the cookie,
      as in the example below.
    

      
    Setting cookie parameters
    Session On
SessionCryptoPassphrase secret
SessionCookieName session path=/private;domain=example.com;httponly;secure;
    

    

      
    In cases where the Apache server forms the frontend for backend origin servers,
      it is possible to have the session cookies removed from the incoming HTTP headers using
      the SessionCookieRemove directive.
      This keeps the contents of the session cookies from becoming accessible from the
      backend server.
      
    

    
    top
    

    

    Session Support for Authentication
    

      
    As is possible within many application servers, authentication modules can use
      a session for storing the username and password after login. The
      mod_auth_form saves the user's login name and password within
      the session.
    

      
    Form based authentication
    Session On
SessionCryptoPassphrase secret
SessionCookieName session path=/
AuthFormProvider file
AuthUserFile "conf/passwd"
AuthType form
AuthName "realm"
#...
    

    

      
    See the mod_auth_form module for documentation and complete
      examples.
    

    
    top
    

    

    Integrating Sessions with External Applications
    

      
    In order for sessions to be useful, it must be possible to share the contents
      of a session with external applications, and it must be possible for an
      external application to write a session of its own.
    

      
     A typical example might be an application that changes a user's password set by
      mod_auth_form. This application would need to read the current
      username and password from the session, make the required changes to the user's
      password, and then write the new password to the session in order to provide a
      seamless transition to the new password.
    

      
    A second example might involve an application that registers a new user for
      the first time. When registration is complete, the username and password is
      written to the session, providing a seamless transition to being logged in.
    

      
    
      
    Apache modules
    
      
    Modules within the server that need access to the session can use the
      mod_session.h API in order to read from and write to the
      session. This mechanism is used by modules like mod_auth_form.
      
    

      
    CGI programs and scripting languages
    
      
    Applications that run within the webserver can optionally retrieve the
      value of the session from the HTTP_SESSION environment
      variable. The session should be encoded as a
      application/x-www-form-urlencoded string as described by the
      HTML specification. The environment
      variable is controlled by the setting of the
      SessionEnv directive. The session
      can be written to by the script by returning a
      application/x-www-form-urlencoded response header with a name
      set by the SessionHeader
      directive. In both cases, any encryption or decryption, and the reading the
      session from or writing the session to the chosen storage mechanism is handled
      by the mod_session modules and corresponding configuration.
      
    

      
    Applications behind mod_proxy
    
      
    If the SessionHeader
      directive is used to define an HTTP request header, the session, encoded as
      a application/x-www-form-urlencoded string, will be made
      available to the application. If the same header is provided in the response,
      the value of this response header will be used to replace the session. As
      above, any encryption or decryption, and the reading the session from or
      writing the session to the chosen storage mechanism is handled by the
      mod_session modules and corresponding configuration.
    

      
    Standalone applications
    
      
    Applications might choose to manipulate the session outside the control
      of the Apache HTTP server. In this case, it is the responsibility of the
      application to read the session from the chosen storage mechanism,
      decrypt the session, update the session, encrypt the session and write
      the session to the chosen storage mechanism, as appropriate.

    Session Directive
    

    

    Description:Enables a session for the current directory or location
    

    Syntax:Session On|Off
    

    Default:Session Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_session
    

    
    
    The Session directive enables a session for the
    directory or location container. Further directives control where the
    session will be stored and how privacy is maintained.
    


    

    top
    

    SessionEnv Directive
    

    

    Description:Control whether the contents of the session are written to the
HTTP_SESSION environment variable
    

    Syntax:SessionEnv On|Off
    

    Default:SessionEnv Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_session
    

    
    
    If set to On, the SessionEnv directive
    causes the contents of the session to be written to a CGI environment
    variable called HTTP_SESSION.
    

    
    The string is written in the URL query format, for example:
    

    
    
      key1=foo&key3=bar
    
    



    

    top
    

    SessionExclude Directive
    

    

    Description:Define URL prefixes for which a session is ignored
    

    Syntax:SessionExclude path
    

    Default:none
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_session
    

    
    
    The SessionExclude directive allows sessions to
    be disabled relative to URL prefixes only. This can be used to make a
    website more efficient, by targeting a more precise URL space for which
    a session should be maintained. By default, all URLs within the directory
    or location are included in the session. The
    SessionExclude directive takes
    precedence over the
    SessionInclude directive.
    

    
    Warning
    
    
    This directive has a similar purpose to the path attribute
    in HTTP cookies, but should not be confused with this attribute. This
    directive does not set the path attribute, which must be
    configured separately.
    


    

    top
    

    SessionExpiryUpdateInterval Directive
    

    

    Description:Define the number of seconds a session's expiry may change without
the session being updated
    

    Syntax:SessionExpiryUpdateInterval interval
    

    Default:SessionExpiryUpdateInterval 0 (always update)
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_session
    

    Compatibility:Available in Apache 2.4.41 and later
    

    
    
    The SessionExpiryUpdateInterval directive allows
    sessions to avoid the cost associated with writing the session each request
    when only the expiry time has changed. This can be used to make a website
    more efficient or reduce load on a database when using
    mod_session_dbd. The session is always written if the data
    stored in the session has changed or the expiry has changed by more than the
    configured interval.
    

    
    Setting the interval to zero disables this directive, and the session
    expiry is refreshed for each request.
    

    
    This directive only has an effect when combined with
    SessionMaxAge to enable session
    expiry. Sessions without an expiry are only written when the data stored in
    the session has changed.
    

    
    Warning
    
    
    Because the session expiry may not be refreshed with each request, it's
    possible for sessions to expire up to interval seconds early.
    Using a small interval usually provides sufficient savings while having a
    minimal effect on expiry resolution.
    


    

    top
    

    SessionHeader Directive
    

    

    Description:Import session updates from a given HTTP response header
    

    Syntax:SessionHeader header
    

    Default:none
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_session
    

    
    
    The SessionHeader directive defines the name of an
    HTTP response header which, if present, will be parsed and written to the
    current session.
    

    
    The header value is expected to be in the URL query format, for example:
    

    
    
      key1=foo&key2=&key3=bar
    
    

    
    Where a key is set to the empty string, that key will be removed from the
    session.
    



    

    top
    

    SessionInclude Directive
    

    

    Description:Define URL prefixes for which a session is valid
    

    Syntax:SessionInclude path
    

    Default:all URLs
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_session
    

    
    
    The SessionInclude directive allows sessions to
    be made valid for specific URL prefixes only. This can be used to make a
    website more efficient, by targeting a more precise URL space for which
    a session should be maintained. By default, all URLs within the directory
    or location are included in the session.
    

    
    Warning
    
    
    This directive has a similar purpose to the path attribute
    in HTTP cookies, but should not be confused with this attribute. This
    directive does not set the path attribute, which must be
    configured separately.
    


    

    top
    

    SessionMaxAge Directive
    

    

    Description:Define a maximum age in seconds for a session
    

    Syntax:SessionMaxAge maxage
    

    Default:SessionMaxAge 0
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_session
    

    
    
    The SessionMaxAge directive defines a time limit
    for which a session will remain valid. When a session is saved, this time
    limit is reset and an existing session can be continued. If a session
    becomes older than this limit without a request to the server to refresh
    the session, the session will time out and be removed. Where a session is
    used to stored user login details, this has the effect of logging the user
    out automatically after the given time.
    

    
    Setting the maxage to zero disables session expiry.

      Bu yönergeyi kullanırken dikkatli olun; örneğin, "UserDir
        ./" şeklinde bir atama "/~root" isteklerini
        "/" dizinine yönlendirir ki bu elbette istenmez. Bu
        bakımdan yapılandırmanızda mutlaka bir "UserDir disabled
        root" satırının yer almasını tavsiye ederiz. Daha fazla bilgi
        için Directory yönergesine ve Güvenlik İpuçları sayfasına
        bakınız.
    
    

    
    Diğer örnekler:

    UserDir disabled
UserDir enabled birey1 birey2 birey3
    


    
    Bir kaç kullanıcı hariç kalan herkesin UserDir
      dizinlerini etkin kılmak için şunu yapabilirsiniz:

    Birden fazla dizin belirtmek de mümkündür:
    

    
    Userdir "public_html" "/usr/siteler" "http://example.com/"
    


    
    Bu örneğe göre, http://example.com/~ali/bir/iki.html
      şeklinde bir istek alındığında sunucu önce
      http://example.com/~ali/bir/iki.html yönlendirmesini
      deneyecektir. Onu bulamazsa isteği
      /usr/siteler/ali/bir/iki.html dosyasını arayacak onu da
      bulamazsa istemciyi http://example.com/ali/bir/iki.html
      adresine yönlendirecektir.
    

    
    Argüman listesine bir yönlendirme ekleyecekseniz, bu, listenin son
      elemanı olmalıdır. Apache httpd yönlendirmenin başarılı sonuç verip
      vermediğini bilemeyecektir. Bu bakımdan, listede bu yönlendirmeden
      sonra bir yönlendirme daha bulunması daha iyi olacaktır.

    Apache HTTP Server Version 2.4

    Apache Module mod_dav
    

    

    Available Languages:  en  |

    Description:Distributed Authoring and Versioning
(WebDAV) functionality
    

    Status:Extension
    

    Module Identifier:dav_module
    

    Source File:mod_dav.c
    

    Summary
    

    
    This module provides class 1 and class 2 WebDAV ('Web-based Distributed
    Authoring and Versioning') functionality for Apache. This
    extension to the HTTP protocol allows creating, moving,
    copying, and deleting resources and collections on a remote web
    server.
    

    


    top
    

    

    Enabling WebDAV
    
    
    To enable mod_dav, add the following to a
    container in your httpd.conf file:
    

    
    Dav On
    


    
    This enables the DAV file system provider, which is implemented
    by the mod_dav_fs module. Therefore, that module
    must be compiled into the server or loaded at runtime using the
    LoadModule directive.
    

    
    In addition, a location for the DAV lock database must be
    specified in the global section of your httpd.conf
    file using the DavLockDB
    directive:
    

    
    DavLockDB /usr/local/apache2/var/DavLock
    


    
    The directory containing the lock database file must be
    writable by the User
    and Group under which
    Apache is running.
    

    
    You may wish to add a <Limit> clause inside the <Location> directive to limit access to
    DAV-enabled locations. If you want to set the maximum amount of
    bytes that a DAV client can send at one request, you have to use
    the LimitXMLRequestBody
    directive. The "normal" LimitRequestBody directive has no effect on DAV
    requests.
    

    
    Full Example
    DavLockDB "/usr/local/apache2/var/DavLock"

<Directory "/usr/local/apache2/htdocs/foo">
    Require all granted
    Dav On

    AuthType Basic
    AuthName DAV
    AuthUserFile "user.passwd"

    <LimitExcept GET POST OPTIONS>
        Require user admin
    </LimitExcept>
</Directory>
    

    


    top
    

    

    Security Issues
    

    
    Since DAV access methods allow remote clients to manipulate
    files on the server, you must take particular care to assure that
    your server is secure before enabling mod_dav.
    

    
    Any location on the server where DAV is enabled should be
    protected by authentication.  The use of HTTP Basic Authentication
    is not recommended. You should use at least HTTP Digest
    Authentication, which is provided by the
    mod_auth_digest module. Nearly all WebDAV clients
    support this authentication method. An alternative is Basic
    Authentication over an SSL enabled
    connection.
    

    
    In order for mod_dav to manage files, it must
    be able to write to the directories and files under its control
    using the User and
    Group under which
    Apache is running.  New files created will also be owned by this
    User and Group.  For this reason, it is
    important to control access to this account.  The DAV repository
    is considered private to Apache; modifying files outside of Apache
    (for example using FTP or filesystem-level tools) should not be
    allowed.
    

    
    mod_dav may be subject to various kinds of
    denial-of-service attacks.  The LimitXMLRequestBody directive can be
    used to limit the amount of memory consumed in parsing large DAV
    requests.  The DavDepthInfinity directive can be
    used to prevent PROPFIND requests on a very large
    repository from consuming large amounts of memory.  Another
    possible denial-of-service attack involves a client simply filling
    up all available disk space with many large files.  There is no
    direct way to prevent this in Apache, so you should avoid giving
    DAV access to untrusted users.
    

    top
    

    

    Complex Configurations
    

    
    One common request is to use mod_dav to
    manipulate dynamic files (PHP scripts, CGI scripts, etc).  This is
    difficult because a GET request will always run the
    script, rather than downloading its contents.  One way to avoid
    this is to map two different URLs to the content, one of which
    will run the script, and one of which will allow it to be
    downloaded and manipulated with DAV.
    


    Alias "/phparea" "/home/gstein/php_files"
Alias "/php-source" "/home/gstein/php_files"
<Location "/php-source">
    Dav On
    ForceType text/plain
</Location>
    


    
    With this setup, http://example.com/phparea can be
    used to access the output of the PHP scripts, and
    http://example.com/php-source can be used with a DAV
    client to manipulate them.

    Dav Directive
    

    

    Description:Enable WebDAV HTTP methods
    

    Syntax:Dav On|Off|provider-name
    

    Default:Dav Off
    

    Context:directory
    

    Status:Extension
    

    Module:mod_dav
    

    
    
    Use the Dav directive to enable the
    WebDAV HTTP methods for the given container:
    

    
    <Location "/foo">
    Dav On
</Location>
    


    
    The value On is actually an alias for the default
    provider filesystem which is served by the mod_dav_fs module. Note, that once you have DAV enabled
    for some location, it cannot be disabled for sublocations.
    For a complete configuration example have a look at the section above.
    

    
    
      Do not enable WebDAV until you have secured your server. Otherwise
      everyone will be able to distribute files on your system.
    
    


    

    top
    

    DavDepthInfinity Directive
    

    

    Description:Allow PROPFIND, Depth: Infinity requests
    

    Syntax:DavDepthInfinity on|off
    

    Default:DavDepthInfinity off
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_dav
    

    
    
    Use the DavDepthInfinity directive to
    allow the processing of PROPFIND requests containing the
    header 'Depth: Infinity'. Because this type of request could constitute
    a denial-of-service attack, by default it is not allowed.
    


    

    top
    

    DavMinTimeout Directive
    

    

    Description:Minimum amount of time the server holds a lock on
a DAV resource
    

    Syntax:DavMinTimeout seconds
    

    Default:DavMinTimeout 0
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_dav
    

    
    
    When a client requests a DAV resource lock, it can also
    specify a time when the lock will be automatically removed by
    the server. This value is only a request, and the server can
    ignore it or inform the client of an arbitrary value.
    

    
    Use the DavMinTimeout directive to specify, in
    seconds, the minimum lock timeout to return to a client.
    Microsoft Web Folders defaults to a timeout of 120 seconds; the
    DavMinTimeout can override this to a higher value
    (like 600 seconds) to reduce the chance of the client losing
    the lock due to network latency.
    

    
    Example
    <Location "/MSWord">
    DavMinTimeout 600
</Location>

    Summary
    

    
    Warning
    
      
    The session modules make use of HTTP cookies, and as such can fall
      victim to Cross Site Scripting attacks, or expose potentially private
      information to clients. Please ensure that the relevant risks have
      been taken into account before enabling the session functionality on
      your server.
    
    
    

    
    This submodule of mod_session provides support for the
    encryption of user sessions before being written to a local database, or
    written to a remote browser via an HTTP cookie.
    

    
    This can help provide privacy to user sessions where the contents of
    the session should be kept private from the user, or where protection is
    needed against the effects of cross site scripting attacks.
    

    
    For more details on the session interface, see the documentation for
    the mod_session module.
    


    


    top
    

    

    Basic Usage
    

      
    To create a simple encrypted session and store it in a cookie called
      session, configure the session as follows:
    

      
    Browser based encrypted session
    Session On
SessionCookieName session path=/
SessionCryptoPassphrase secret
    

    

      
    The session will be encrypted with the given key. Different servers can
      be configured to share sessions by ensuring the same encryption key is used
      on each server.
    

      
    If the encryption key is changed, sessions will be invalidated
      automatically.
    

      
    For documentation on how the session can be used to store username
      and password details, see the mod_auth_form module.
    

    
    

    top
    

    SessionCryptoCipher Directive
    

    

    Description:The crypto cipher to be used to encrypt the session
    

    Syntax:SessionCryptoCipher name
    

    Default:SessionCryptoCipher aes256
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Experimental
    

    Module:mod_session_crypto
    

    Compatibility:Available in Apache 2.3.0 and later
    

    
    
    The SessionCryptoCipher directive allows the cipher to
    be used during encryption. If not specified, the cipher defaults to
    aes256.
    

    
    Possible values depend on the crypto driver in use, and could be one of:
    

    
    • 3des192
    • aes128
    • aes192
    • aes256
    



    

    top
    

    SessionCryptoDriver Directive
    

    

    Description:The crypto driver to be used to encrypt the session
    

    Syntax:SessionCryptoDriver name [param[=value]]
    

    Default:none
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_session_crypto
    

    Compatibility:Available in Apache 2.3.0 and later
    

    
    
    The SessionCryptoDriver directive specifies the name of
    the crypto driver to be used for encryption. If not specified, the driver defaults
    to the recommended driver compiled into APR-util.
    

    
    The NSS crypto driver requires some parameters for configuration,
    which are specified as parameters with optional values after the driver name.
    

    
    NSS without a certificate database
    SessionCryptoDriver nss
    

    

    
    NSS with certificate database
    SessionCryptoDriver nss dir=certs
    

    

    
    NSS with certificate database and parameters
    SessionCryptoDriver nss dir=certs key3=key3.db cert7=cert7.db secmod=secmod
    

    

    
    NSS with paths containing spaces
    SessionCryptoDriver nss "dir=My Certs" key3=key3.db cert7=cert7.db secmod=secmod
    

    

    
    The NSS crypto driver might have already been
    configured by another part of the server, for example from
    mod_nss or mod_ldap. If found to
    have already been configured, a warning will be logged, and the
    existing configuration will have taken affect.  To avoid this
    warning, use the noinit parameter as follows.
    

    
    NSS with certificate database
    SessionCryptoDriver nss noinit
    

    

    
    To prevent confusion, ensure that all modules requiring NSS are configured with
    identical parameters.
    

    
    The openssl crypto driver supports an optional parameter to specify
    the engine to be used for encryption.
    

    
    OpenSSL with engine support
    SessionCryptoDriver openssl engine=name
    

    



    

    top
    

    SessionCryptoPassphrase Directive
    

    

    Description:The key used to encrypt the session
    

    Syntax:SessionCryptoPassphrase secret [ secret ... ] 
    

    Default:none
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Experimental
    

    Module:mod_session_crypto
    

    Compatibility:Available in Apache 2.3.0 and later
    

    
    
    The SessionCryptoPassphrase directive specifies the keys
    to be used to enable symmetrical encryption on the contents of the session before
    writing the session, or decrypting the contents of the session after reading the
    session.
    

    
    Keys are more secure when they are long, and consist of truly random characters.
    Changing the key on a server has the effect of invalidating all existing sessions.
    

    
    Multiple keys can be specified in order to support key rotation. The first key
    listed will be used for encryption, while all keys listed will be attempted for
    decryption. To rotate keys across multiple servers over a period of time, add a new
    secret to the end of the list, and once rolled out completely to all servers, remove
    the first key from the start of the list.
    

    
    As of version 2.4.7 if the value begins with exec: the resulting command
    will be executed and the first line returned to standard output by the program will be
    used as the key.
    

    #key used as-is
SessionCryptoPassphrase secret

#Run /path/to/program to get key
SessionCryptoPassphrase exec:/path/to/program

#Run /path/to/otherProgram and provide arguments
SessionCryptoPassphrase "exec:/path/to/otherProgram argument1"
    

    



    

    top
    

    SessionCryptoPassphraseFile Directive
    

    

    Description:File containing keys used to encrypt the session
    

    Syntax:SessionCryptoPassphraseFile filename
    

    Default:none
    

    Context:server config, virtual host, directory
    

    Status:Experimental
    

    Module:mod_session_crypto
    

    Compatibility:Available in Apache 2.3.0 and later
    

    
    
    The SessionCryptoPassphraseFile directive specifies the
    name of a configuration file containing the keys to use for encrypting or decrypting
    the session, specified one per line. The file is read on server start, and a graceful
    restart will be necessary for httpd to pick up changes to the keys.
    

    
    Unlike the SessionCryptoPassphrase directive, the keys are
    not exposed within the httpd configuration and can be hidden by protecting the file
    appropriately.
    

    
    Multiple keys can be specified in order to support key rotation. The first key
    listed will be used for encryption, while all keys listed will be attempted for
    decryption. To rotate keys across multiple servers over a period of time, add a new
    secret to the end of the list, and once rolled out completely to all servers, remove
    the first key from the start of the list.

    Avertissement
    
      
    Les modules de session font usage des cookies HTTP, et peuvent
      à ce titre être victimes d'attaques de type Cross Site Scripting,
      ou divulguer des informations à caractère privé aux clients.
      Veuillez vous assurer que les risques ainsi encourus ont été pris
      en compte avant d'activer le support des sessions sur votre
      serveur.
    
    
    

    
    Ce sous-module du module mod_session fournit le
    support du chiffrement des sessions utilisateur avant de les
    enregistrer dans une base de données locale, ou dans un cookie HTTP
    au niveau du navigateur distant.
    

    
    Il peut contribuer à préserver la confidentialité des sessions
    lorsque leur contenu doit rester privé pour
    l'utilisateur, ou lorsqu'une protection contre les attaques de type
    cross site scripting est nécessaire.

    Utilisation de base
    

      
    Pour créer une session chiffrée et la stocker dans un cookie
      nommé session, configurez la comme suit :
    

      
    Session chiffrée stockée au niveau du
      serveur
    Session On
SessionCookieName session path=/
SessionCryptoPassphrase secret
    

    

      
    La session sera chiffrée avec la clé spécifiée. Il est possible
      de configurer plusieurs serveurs pour qu'ils puissent partager des
      sessions, en s'assurant que la même clé de chiffrement est
      utilisée sur chaque serveur.
    

      
    Si la clé de chiffrement est modifiée, les sessions seront
      automatiquement invalidées.
    

      
    Pour des détails sur la manière dont une session peut être
      utilisée pour stocker des informations de type nom
      d'utilisateur/mot de passe, voir la documentation du module
      mod_auth_form.

    La directive SessionCryptoCipher permet de
    spécifier l'algorithme à utiliser pour le chiffrement. En l'absence
    de spécification, l'algorithme par défaut est aes256.
    

    
    L'algorithme peut être choisi, en fonction du moteur de chiffrement
    utilisé, parmi les valeurs suivantes :
    

    
    • 3des192
    • aes128
    • aes192
    • aes256

    La directive SessionCryptoDriver permet de
    spécifier le nom du pilote à utiliser pour le chiffrement. Si aucun
    pilote n'est spécifié, le pilote utilisé par défaut sera le pilote
    recommandé compilé avec APR-util.
    

    
    Le pilote de chiffrement NSS nécessite certains
    paramètres de configuration, qui seront spécifiés comme arguments de
    la directive avec des valeurs optionnelles après le nom du
    pilote.
    

    
    NSS sans base de données de certificats
    SessionCryptoDriver nss
    

    

    
    NSS avec base de données de certificats
    SessionCryptoDriver nss dir=certs
    

    

    
    NSS avec base de données de certificats et
    paramètres
    SessionCryptoDriver nss dir=certs clé3=clé3.db cert7=cert7.db secmod=secmod
    

    

    
    NSS avec chemins contenant des espaces
    SessionCryptoDriver nss "dir=My Certs" key3=key3.db cert7=cert7.db secmod=secmod
    

    

    
    Le pilote de chiffrement NSS peut avoir été configuré
    au préalable dans une autre partie du serveur, par exemple depuis
    mod_nss ou mod_ldap. Si c'est le
    cas, un avertissement sera enregistré dans le journal, et la
    configuration existante s'en trouvera affectée. Pour éviter cet
    avertissement, utilisez le paramètre noinit comme suit :
    

    
    NSS avec base de données de certificats
    SessionCryptoDriver nss noinit
    

    

    
    Pour éviter la confusion, assurez-vous que tous les modules
    utilisant NSS soient configurés avec des paramètres identiques.
    

    
    Le pilote de chiffrement openssl accepte un paramètre
    optionnel permettant de spécifier le moteur de chiffrement à
    utiliser.
    

    
    OpenSSL avec spécification du moteur de chiffrement
    SessionCryptoDriver openssl engine=nom-moteur

    Directive SessionCryptoPassphrase

    La directive SessionCryptoPassphrase
    permet de spécifier les clés à utiliser pour chiffrer de manière
    symétrique le contenu de la session avant de l'enregistrer, ou pour
    déchiffrer le contenu de la session après sa lecture.
    

    
    L'utilisation de clés longues et composées de caractères vraiment
    aléatoires est plus performant en matière de sécurité. Modifier une
    clé sur un serveur a pour effet d'invalider toutes les sessions
    existantes.
    

    
    Il est possible de spécifier plusieurs clés afin de mettre en
    oeuvre la rotation de clés. La première clé spécifiée sera utilisée
    pour le chiffrement, alors que l'ensemble des clés spécifiées le
    sera pour le déchiffrement. Pour effectuer une rotation périodique
    des clés sur plusieurs serveurs, ajoutez une nouvelle clé en fin de
    liste, puis, une fois la rotation complète effectuée, supprimez la
    première clé de la liste.
    

    
    Depuis la version 2.4.7, si la valeur de l'argument commence par exec: , la commande
    spécifiée sera exécutée, et la première ligne que cette dernière
    renverra sur la sortie standard sera utilisée comme clé.
    

    # clé spécifiée et utilisée en tant que tel
SessionCryptoPassphrase secret

# exécution de /path/to/program pour générer la clé
SessionCryptoPassphrase exec:/path/to/program

# exécution de /path/to/program avec un argument pour générer la clé
SessionCryptoPassphrase "exec:/path/to/otherProgram argument1"

    La directive SessionCryptoPassphraseFile
    permet de spécifier le nom d'un fichier de configuration contenant
    les clés à utiliser pour le chiffrement et le déchiffrement de la
    session (une clé par ligne). Le fichier est lu au démarrage du
    serveur, et un redémarrage graceful est nécessaire pour prendre en
    compte un éventuel changement de clés.
    

    
    À la différence de la directive SessionCryptoPassphrase, les
    clés ne sont pas présentes dans le fichier de configuration de
    httpd et peuvent être cachées via une protection
    appropriée du fichier de clés.
    

    
    Il est possible de spécifier plusieurs clés afin de mettre
    en oeuvre la rotation de clés. La première clé
    spécifiée sera utilisée pour le chiffrement, alors que
    l'ensemble des clés spécifiées le sera pour le
    déchiffrement. Pour effectuer une rotation périodique des
    clés sur plusieurs serveurs, ajoutez une nouvelle clé en fin
    de liste, puis, une fois la rotation complète effectuée,
    supprimez la première clé de la liste.

    Sommaire
    

    
    Avertissement
    
      
    Les modules de session font usage des cookies HTTP, et peuvent
      à ce titre être victimes d'attaques de type Cross Site Scripting,
      ou divulguer des informations à caractère privé aux clients.
      Veuillez vous assurer que les risques ainsi encourus ont été pris
      en compte avant d'activer le support des sessions sur votre
      serveur.
    
    
    

    
    Ce sous-module du module mod_session fournit le
    support du stockage des sessions utilisateur au niveau du navigateur
    distant dans des cookies HTTP.
    

    
    L'utilisation de cookies pour stocker les sessions décharge le
    serveur ou le groupe de serveurs de la nécessité de stocker les
    sessions localement, ou de collaborer pour partager les sessions, et
    peut être utile dans les environnements à fort trafic où le stockage
    des sessions sur le serveur pourrait s'avérer trop consommateur de
    ressources.
    

    
    Si la confidentialité de la session doit être préservée, le
    contenu de cette dernière peut être chiffré avant d'être enregistré
    au niveau du client à l'aide du module
    mod_session_crypto.
    

    
    Pour plus de détails à propos de l'interface des sessions, voir
    la documentation du module mod_session.
    


    


    top
    

    

    Exemples simples
    

      
    Pour créer une session et la stocker dans un cookie nommé
      session, configurez-la comme suit :
    

      
    Session stockée au niveau du navigateur
    Session On
SessionCookieName session path=/
    

    

      
    Pour plus d'exemples sur la manière dont une session doit être
      configurée pour qu'une application CGI puisse l'utiliser, voir la
      section exemples de la documentation du module
      mod_session.
    

      
    Pour des détails sur la manière dont une session peut être
      utilisée pour stocker des informations de type nom
      d'utilisateur/mot de passe, voir la documentation du module
      mod_auth_form.

    Dans le cas d'un mandataire inverse où le serveur Apache sert de
    frontal à un serveur d'arrière-plan, révéler le contenu du cookie de
    session à ce dernier peut conduire à une violation de la
    confidentialité. À ce titre, si cette directive est définie à "on",
    le cookie de session sera supprimé des en-têtes HTTP entrants.

    Apache MPM event
    

    

    Available Languages:  en  |

    Description:A variant of the worker MPM with the goal
of consuming threads only for connections with active processing
    

    Status:MPM
    

    Module Identifier:mpm_event_module
    

    Source File:event.c
    

    Summary
    

    
    The event Multi-Processing Module (MPM) is
    designed to allow more requests to be served simultaneously by
    passing off some processing work to the listeners threads, freeing up
    the worker threads to serve new requests.
    

    
    To use the event MPM, add
      --with-mpm=event to the configure
      script's arguments when building the httpd.
    


    


    top
    

    

    Relationship with the Worker MPM
    

    event is based on the worker MPM, which implements a hybrid
multi-process multi-threaded server. A single control process (the parent) is responsible for launching
child processes. Each child process creates a fixed number of server
threads as specified in the ThreadsPerChild directive, as well
as a listener thread which listens for connections and passes them to a worker thread for processing when they arrive.
    


    Run-time configuration directives are identical to those provided by worker, with the only addition
of the AsyncRequestWorkerFactor.
    


    top
    

    

    How it Works
    
    
    This MPM tries to fix the 'keep alive problem' in HTTP. After a client
    completes the first request, it can keep the connection
    open, sending further requests using the same socket and saving
    significant overhead in creating TCP connections. However,
    Apache HTTP Server traditionally keeps an entire child
    process/thread waiting for data from the client, which brings its own disadvantages.
    To solve this problem, this MPM uses a dedicated listener thread for each process
    to handle both the Listening sockets, all sockets that are in a Keep Alive state,
    sockets where the handler and protocol filters have done their work
    and the ones where the only remaining thing to do is send the data to the client.
    
    

    
    This new architecture, leveraging non-blocking sockets and modern kernel
       features exposed by APR (like Linux's epoll),
       no longer requires the mpm-accept Mutex
       configured to avoid the thundering herd problem.
    

    
    The total amount of connections that a single process/threads block can handle is regulated
        by the AsyncRequestWorkerFactor directive.
    

    
    Async connections
    
        
    Async connections would need a fixed dedicated worker thread with the previous MPMs but not with event.
        The status page of mod_status shows new columns under the Async connections section:
    
        
    
            
    Writing
    
	    
    While sending the response to the client, it might happen that the TCP write buffer fills up because the connection is too slow.
	 Usually in this case, a write() to the socket returns EWOULDBLOCK or EAGAIN to become writable again after an idle time.
	 The worker holding the socket might be able to offload the waiting task to the listener thread, that in turn will re-assign it to the first idle worker thread available once an event will be raised for the socket (for example, "the socket is now writable").
	 Please check the Limitations section for more information.
            
    

            
    Keep-alive
    
            
    Keep Alive handling is the most basic improvement from the worker MPM.
            Once a worker thread finishes to flush the response to the client, it can offload the
            socket handling to the listener thread, that in turn will wait for any event from the
            OS, like "the socket is readable". If any new request comes from the client, then the
            listener will forward it to the first worker thread available. Conversely, if the
            KeepAliveTimeout occurs then the socket will be
            closed by the listener. In this way, the worker threads are not responsible for idle
            sockets, and they can be re-used to serve other requests.
    

            
    Closing
    
            
    Sometimes the MPM needs to perform a lingering close, namely sending back an early error to the client while it is still transmitting data to httpd.
            Sending the response and then closing the connection immediately is not the correct thing to do since the client (still trying to send the rest of the
	    request) would get a connection reset and could not read the httpd's response.
	    The lingering close is time-bounded, but it can take a relatively long
	    time, so it's offloaded to a worker thread (including the shutdown hooks and real socket close).
	    From 2.4.28 onward, this is also the
            case when connections finally timeout (the listener thread never handles connections besides waiting for and dispatching their events).
            
    
        
    

        
    These improvements are valid for both HTTP/HTTPS connections.
    

    

    
    Graceful process termination and Scoreboard usage
    
        
    This mpm showed some scalability bottlenecks in the past, leading to the following
        error: "scoreboard is full, not at MaxRequestWorkers".
        MaxRequestWorkers
        limits the number of simultaneous requests that will be served at any given time
        and also the number of allowed processes
        (MaxRequestWorkers 
        / ThreadsPerChild); meanwhile,
        the Scoreboard is a representation of all the running processes and
        the status of their worker threads. If the scoreboard is full (so all the
        threads have a state that is not idle) but the number of active requests
        served is not MaxRequestWorkers,
        it means that some of them are blocking new requests that could be served
        but that are queued instead (up to the limit imposed by
        ListenBacklog). Most of the time,
        the threads are stuck in the Graceful state, namely they are waiting to
        finish their work with a TCP connection to safely terminate and free up a
        scoreboard slot (for example, handling long-running requests, slow clients
        or connections with keep-alive enabled). Two scenarios are very common:
    
        
      
            
    • During a graceful restart,
            the parent process signals all its children to complete
            their work and terminate, while it reloads the config and forks new
            processes. If the old children keep running for a while before stopping,
            the scoreboard will be partially occupied until their slots are freed.
            
      • 
            
    • The server load goes down in a way that causes httpd to
            stop some processes (for example, due to
            MaxSpareThreads).
            This is particularly problematic because when the load increases again,
            httpd will try to start new processes.
            If the pattern repeats, the number of processes can rise quite a bit,
            ending up in a mixture of old processes trying to stop and new ones
            trying to do some work.

    From 2.4.24 onward, mpm-event is smarter and it is able to handle
        graceful terminations in a much better way. Some of the improvements are:
    
        
      
            
    • Allow the use of all the scoreboard slots up to
            ServerLimit.
            MaxRequestWorkers and
            ThreadsPerChild are used
            to limit the amount of active processes; meanwhile,
            ServerLimit 
            takes also into account the ones doing a graceful
            close to allow extra slots when needed. The idea is to use
            ServerLimit to instruct httpd
            about how many overall processes are tolerated before impacting
            the system resources.
            
      • 
            
    • Force gracefully finishing processes to close their
            connections in keep-alive state.
      • 
            
    • During graceful shutdown, if there are more running worker threads
            than open connections for a given process, terminate these threads to
            free resources faster (which may be needed for new processes).
      • 
            
    • If the scoreboard is full, prevent more processes from finishing
            gracefully due to reduced load until old processes have terminated
            (otherwise the situation would get worse once the load increases again).
      • 
        
    
        
    The behavior described in the last point is completely observable via
        mod_status in the connection summary table through two new
        columns: "Slot" and "Stopping". The former indicates the PID and
        the latter if the process is stopping or not; the extra state "Yes (old gen)"
        indicates a process still running after a graceful restart.
    
    

    
    Limitations
    
        
    The improved connection handling may not work for certain connection
        filters that have declared themselves as incompatible with event. In these
        cases, this MPM will fall back to the behavior of the
        worker MPM and reserve one worker thread per connection.
        All modules shipped with the server are compatible with the event MPM.
    

        
    A similar restriction is currently present for requests involving an
        output filter that needs to read and/or modify the whole response body.
        If the connection to the client blocks while the filter is processing the
        data, and the amount of data produced by the filter is too big to be
        buffered in memory, the thread used for the request is not freed while
        httpd waits until the pending data is sent to the client.
    
        To illustrate this point, we can think about the following two situations:
        serving a static asset (like a CSS file) versus serving content retrieved from
        FCGI/CGI or a proxied server. The former is predictable, namely the event MPM
        has full visibility on the end of the content and it can use events: the worker
        thread serving the response content can flush the first bytes until EWOULDBLOCK
        or EAGAIN is returned, delegating the rest to the listener. This one in turn
        waits for an event on the socket and delegates the work to flush the rest of the content
        to the first idle worker thread. Meanwhile in the latter example (FCGI/CGI/proxied content),
        the MPM can't predict the end of the response and a worker thread has to finish its work
        before returning the control to the listener. The only alternative is to buffer the
        response in memory, but it wouldn't be the safest option for the sake of the
        server's stability and memory footprint.
        
    

    

    
    Background material
    
        
    The event model was made possible by the introduction of new APIs into the supported operating systems:
    
        
      
            
    • epoll (Linux) 
      • 
            
    • kqueue (BSD) 
      • 
            
    • event ports (Solaris) 
      • 
        
    
        
    Before these new APIs where made available, the traditional select and poll APIs had to be used.
        Those APIs get slow if used to handle many connections or if the set of connections rate of change is high.
        The new APIs allow to monitor many more connections, and they perform way better when the set of connections to monitor changes frequently. So these APIs made it possible to write the event MPM, that scales much better with the typical HTTP pattern of many idle connections.
    

        
    The MPM assumes that the underlying apr_pollset
        implementation is reasonably threadsafe. This enables the MPM to
        avoid excessive high level locking, or having to wake up the listener
        thread in order to send it a keep-alive socket. This is currently
        only compatible with KQueue and EPoll.
    

    


    top
    

    

    Requirements
    
    
    This MPM depends on APR's atomic
    compare-and-swap operations for thread synchronization. If you are
    compiling for an x86 target and you don't need to support 386s, or
    you are compiling for a SPARC and you don't need to run on
    pre-UltraSPARC chips, add
    --enable-nonportable-atomics=yes to the
    configure script's arguments. This will cause
    APR to implement atomic operations using efficient opcodes not
    available in older CPUs.
    

    
    This MPM does not perform well on older platforms which lack good
    threading, but the requirement for EPoll or KQueue makes this
    moot.
    

    
      

      
    • To use this MPM on FreeBSD, FreeBSD 5.3 or higher is recommended.
      However, it is possible to run this MPM on FreeBSD 5.2.1 if you
      use libkse (see man libmap.conf).
      • 

      
    • For NetBSD, at least version 2.0 is recommended.
      • 

      
    • For Linux, a 2.6 kernel is recommended. It is also necessary to
      ensure that your version of glibc has been compiled
      with support for EPoll.

    AsyncRequestWorkerFactor Directive
    

    

    Description:Limit concurrent connections per process
    

    Syntax:AsyncRequestWorkerFactor factor
    

    Default:2
    

    Context:server config
    

    Status:MPM
    

    Module:event
    

    Compatibility:Available in version 2.3.13 and later
    

    
    
    The event MPM handles some connections in an asynchronous way, where
    request worker threads are only allocated for short periods of time as
    needed, and other connections with one request worker thread reserved per
    connection. This can lead to situations where all workers are tied up and
    no worker thread is available to handle new work on established async
    connections.
    

    
    To mitigate this problem, the event MPM does two things:
    
    
      
        
    • It limits the number of connections accepted per process, depending on the
            number of idle request workers;
      • 
        
    • If all workers are busy, it will
            close connections in keep-alive state even if the keep-alive timeout has
            not expired. This allows the respective clients to reconnect to a
            different process which may still have worker threads available.
      • 
    
    

    
    This directive can be used to fine-tune the per-process connection
    limit. A process will only accept new connections if the current number of
    connections (not counting connections in the "closing" state) is lower
    than:
    

    
    
        ThreadsPerChild +
        (AsyncRequestWorkerFactor *
        number of idle workers)
    
    

    
    An estimation of the maximum concurrent connections across all the processes given
        an average value of idle worker threads can be calculated with:
    
    


    
    
        (ThreadsPerChild +
        (AsyncRequestWorkerFactor *
        number of idle workers)) *
        ServerLimit
    
    

    
    Example
    
    
    ThreadsPerChild = 10
ServerLimit = 4
AsyncRequestWorkerFactor = 2
MaxRequestWorkers = 40

idle_workers = 4 (average for all the processes to keep it simple)

max_connections = (ThreadsPerChild + (AsyncRequestWorkerFactor * idle_workers)) * ServerLimit
                = (10 + (2 * 4)) * 4 = 72
    

    
    

    
    When all the worker threads are idle, then absolute maximum numbers of concurrent
        connections can be calculared in a simpler way:
    

    
    
        (AsyncRequestWorkerFactor + 1) *
        MaxRequestWorkers
    
    


    
    Example
    
    
    ThreadsPerChild = 10
ServerLimit = 4
MaxRequestWorkers = 40
AsyncRequestWorkerFactor = 2
    


    
    If all the processes have all threads idle then: 
    

    
    idle_workers = 10
    


    
    We can calculate the absolute maximum numbers of concurrent connections in two ways:
    

    
    max_connections = (ThreadsPerChild + (AsyncRequestWorkerFactor * idle_workers)) * ServerLimit
                = (10 + (2 * 10)) * 4 = 120

max_connections = (AsyncRequestWorkerFactor + 1) * MaxRequestWorkers
                = (2 + 1) * 40 = 120
    

    
    

    
    Tuning AsyncRequestWorkerFactor requires knowledge about the traffic handled by httpd in each specific use case, so changing the default value requires extensive testing and data gathering from mod_status.
    

    
    MaxRequestWorkers was called
    MaxClients prior to version 2.3.13. The above value
    shows that the old name did not accurately describe its meaning for the event MPM.
    

    
    AsyncRequestWorkerFactor can take non-integer
    arguments, e.g "1.5".

    Summary
    

    
    This module provides authorization capabilities so that
    authenticated users can be allowed or denied access to portions
    of the web site. mod_authz_user grants
    access if the authenticated user is listed in a Require user
    directive. Alternatively Require valid-user can be used to
    grant access to all successfully authenticated users.

    The Require Directives
    

    
    Apache's Require
    directives are used during the authorization phase to ensure that
    a user is allowed to access a resource.  mod_authz_user extends the
    authorization types with user and valid-user.
    
    

    
    Since v2.4.8, expressions are supported
    within the user require directives.
    


    Require user
    

    
    This directive specifies a list of users that are allowed to gain
    access.
    

    
    Require user john paul george ringo
    





    Require valid-user
    

    
    When this directive is specified, any successfully authenticated
    user will be allowed to gain access.
    

    
    Require valid-user

    Description:Provides for mapping different parts of the host
    filesystem in the document tree and for URL redirection
    

    Status:Base
    

    Module Identifier:alias_module
    

    Source File:mod_alias.c
    

    Summary
    

    
    The directives contained in this module allow for manipulation
    and control of URLs as requests arrive at the server. The
    Alias and ScriptAlias directives are used to
    map between URLs and filesystem paths.  This allows for content
    which is not directly under the DocumentRoot served as part of the web
    document tree. The ScriptAlias directive has the
    additional effect of marking the target directory as containing
    only CGI scripts.
    

    
    The Redirect
    directives are used to instruct clients to make a new request with
    a different URL. They are often used when a resource has moved to
    a new location.
    

    
    When the Alias,
    ScriptAlias and
    Redirect directives are used
    within a <Location>
    or <LocationMatch>
    section, expression syntax can be used
    to manipulate the destination path or URL.
    
    

    
    mod_alias is designed to handle simple URL
    manipulation tasks.  For more complicated tasks such as
    manipulating the query string, use the tools provided by
    mod_rewrite.

    Order of Processing
    

    
    Aliases and Redirects occurring in different contexts are processed
    like other directives according to standard merging rules.  But when multiple
    Aliases or Redirects occur in the same context (for example, in the
    same <VirtualHost>
    section) they are processed in a particular order.
    

    
    First, all Redirects are processed before Aliases are processed,
    and therefore a request that matches a Redirect or RedirectMatch will never have Aliases
    applied.  Second, the Aliases and Redirects are processed in the order
    they appear in the configuration files, with the first match taking
    precedence.
    

    
    For this reason, when two or more of these directives apply to the
    same sub-path, you must list the most specific path first in order for
    all the directives to have an effect.  For example, the following
    configuration will work as expected:
    

    
    Alias "/foo/bar" "/baz"
Alias "/foo" "/gaq"
    


    
    But if the above two directives were reversed in order, the
    /foo Alias
    would always match before the /foo/bar Alias, so the latter directive would be
    ignored.
    

    
    When the Alias,
    ScriptAlias and
    Redirect directives are used
    within a <Location>
    or <LocationMatch>
    section, these directives will take precedence over any globally
    defined Alias,
    ScriptAlias and
    Redirect directives.

    Alias Directive
    

    

    Description:Maps URLs to filesystem locations
    

    Syntax:Alias [URL-path]
file-path|directory-path
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_alias
    

    

    
    The Alias directive allows documents to
    be stored in the local filesystem other than under the
    DocumentRoot. URLs with a
    (%-decoded) path beginning with URL-path will be mapped
    to local files beginning with directory-path.  The
    URL-path is case-sensitive, even on case-insensitive
    file systems.
    

    
    Alias "/image" "/ftp/pub/image"
    


    
    A request for http://example.com/image/foo.gif would cause
    the server to return the file /ftp/pub/image/foo.gif.  Only
    complete path segments are matched, so the above alias would not match a
    request for http://example.com/imagefoo.gif.  For more complex
    matching using regular expressions, see the AliasMatch directive.
    

    
    Note that if you include a trailing / on the
    URL-path then the server will require a trailing / in
    order to expand the alias. That is, if you use
    

    
    Alias "/icons/" "/usr/local/apache/icons/"
    


    
    then the URL /icons will not be aliased, as it lacks
    that trailing /. Likewise, if you omit the slash on the
    URL-path then you must also omit it from the
    file-path.
    

    
    Note that you may need to specify additional <Directory> sections which
    cover the destination of aliases.  Aliasing occurs before
    <Directory> sections
    are checked, so only the destination of aliases are affected.
    (Note however <Location>
    sections are run through once before aliases are performed, so
    they will apply.)
    

    
    In particular, if you are creating an Alias to a
    directory outside of your DocumentRoot, you may need to explicitly
    permit access to the target directory.
    

    
    Alias "/image" "/ftp/pub/image"
<Directory "/ftp/pub/image">
    Require all granted
</Directory>
    


    
    Any number slashes in the URL-path parameter
    matches any number of slashes in the requested URL-path.
    

    
    If the Alias directive is used within a
    <Location>
    or <LocationMatch>
    section the URL-path is omitted, and the file-path is interpreted
    using expression syntax.
    
    This syntax is available in Apache 2.4.19 and later.
    

    
    <Location "/image">
    Alias "/ftp/pub/image"
</Location>
<LocationMatch "/error/(?<NUMBER>[0-9]+)">
    Alias "/usr/local/apache/errors/%{env:MATCH_NUMBER}.html"
</LocationMatch>

    AliasMatch Directive
    

    

    Description:Maps URLs to filesystem locations using regular
expressions
    

    Syntax:AliasMatch regex
file-path|directory-path
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_alias
    

    
    
    This directive is equivalent to Alias, but makes use of
    regular expressions,
    instead of simple prefix matching. The
    supplied regular expression is matched against the URL-path, and
    if it matches, the server will substitute any parenthesized
    matches into the given string and use it as a filename. For
    example, to activate the /icons directory, one might
    use:
    

    
    AliasMatch "^/icons(/|$)(.*)" "/usr/local/apache/icons$1$2"
    


    
    The full range of regular expression
    power is available.  For example,
    it is possible to construct an alias with case-insensitive
    matching of the URL-path:
    

    
    AliasMatch "(?i)^/image(.*)" "/ftp/pub/image$1"
    


    
    One subtle difference
    between Alias
    and AliasMatch is
    that Alias will
    automatically copy any additional part of the URI, past the part
    that matched, onto the end of the file path on the right side,
    while AliasMatch will
    not.  This means that in almost all cases, you will want the
    regular expression to match the entire request URI from beginning
    to end, and to use substitution on the right side.
    

    
    In other words, just changing
    Alias to
    AliasMatch will not
    have the same effect.  At a minimum, you need to
    add ^ to the beginning of the regular expression
    and add (.*)$ to the end, and add $1 to
    the end of the replacement.
    

    
    For example, suppose you want to replace this with AliasMatch:
    

    
    Alias "/image/" "/ftp/pub/image/"
    


    
    This is NOT equivalent - don't do this!  This will send all
    requests that have /image/ anywhere in them to /ftp/pub/image/:
    

    
    AliasMatch "/image/" "/ftp/pub/image/"
    


    
    This is what you need to get the same effect:
    

    
    AliasMatch "^/image/(.*)$" "/ftp/pub/image/$1"
    


    
    Of course, there's no point in
    using AliasMatch
    where Alias would
    work.  AliasMatch lets
    you do more complicated things.  For example, you could
    serve different kinds of files from different directories:
    

    
    AliasMatch "^/image/(.*)\.jpg$" "/files/jpg.images/$1.jpg"
AliasMatch "^/image/(.*)\.gif$" "/files/gif.images/$1.gif"
    


    
    Multiple leading slashes in the requested URL are discarded
       by the server before directives from this module compares
       against the requested URL-path.

    Redirect Directive
    

    

    Description:Sends an external redirect asking the client to fetch
a different URL
    

    Syntax:Redirect [status] [URL-path]
URL
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_alias
    

    
    
    The Redirect directive maps an old URL into a new one by asking
    the client to refetch the resource at the new location.
    

    
    The old URL-path is a case-sensitive (%-decoded) path
    beginning with a slash.  A relative path is not allowed.
    

    
    The new URL may be either an absolute URL beginning
    with a scheme and hostname, or a URL-path beginning with a slash.
    In this latter case the scheme and hostname of the current server will
    be added.
    

    
    Then any request beginning with URL-path will return a
    redirect request to the client at the location of the target
    URL.  Additional path information beyond the matched
    URL-path will be appended to the target URL.
    

    
    # Redirect to a URL on a different host
Redirect "/service" "http://foo2.example.com/service"

# Redirect to a URL on the same host
Redirect "/one" "/two"
    


    
    If the client requests http://example.com/service/foo.txt,
    it will be told to access
    http://foo2.example.com/service/foo.txt
    instead. This includes requests with GET parameters, such as
    http://example.com/service/foo.pl?q=23&a=42,
    it will be redirected to
    http://foo2.example.com/service/foo.pl?q=23&a=42.
    Note that POSTs will be discarded.
    
    Only complete path segments are matched, so the above
    example would not match a request for
    http://example.com/servicefoo.txt. For more complex matching
    using the expression syntax, omit the URL-path
    argument as described below. Alternatively, for matching using regular
    expressions, see the RedirectMatch directive.
    


    
    Note
    
    
    Redirect directives take precedence over Alias and ScriptAlias
    directives, irrespective of their ordering in the configuration
    file. Redirect directives inside a Location take
    precedence over Redirect and Alias directives with an URL-path.
    
    
    

    
    If no status argument is given, the redirect will
    be "temporary" (HTTP status 302). This indicates to the client
    that the resource has moved temporarily. The status
    argument can be used to return other HTTP status codes:
    

    
    
      
    permanent
    

      
    Returns a permanent redirect status (301) indicating that
      the resource has moved permanently.
    

      
    temp
    

      
    Returns a temporary redirect status (302). This is the
      default.
    

      
    seeother
    

      
    Returns a "See Other" status (303) indicating that the
      resource has been replaced.
    

      
    gone
    

      
    Returns a "Gone" status (410) indicating that the
      resource has been permanently removed. When this status is
      used the URL argument should be omitted.
    
    
    

    
    Other status codes can be returned by giving the numeric
    status code as the value of status. If the status is
    between 300 and 399, the URL argument must be present.
    If the status is not between 300 and 399, the
    URL argument must be omitted. The status must be a valid
    HTTP status code, known to the Apache HTTP Server (see the function
    send_error_response in http_protocol.c).
    

    
    Redirect permanent "/one" "http://example.com/two"
Redirect 303 "/three" "http://example.com/other"
    


    
    If the Redirect directive is used within a
    <Location>
    or <LocationMatch>
    section with the URL-path omitted, then the URL parameter
    will be interpreted using expression syntax.
    
    This syntax is available in Apache 2.4.19 and later.
    

    
    <Location "/one">
    Redirect permanent "http://example.com/two"
</Location>
<Location "/three">
    Redirect 303 "http://example.com/other"
</Location>
<LocationMatch "/error/(?<NUMBER>[0-9]+)">
    Redirect permanent "http://example.com/errors/%{env:MATCH_NUMBER}.html"
</LocationMatch>

    RedirectMatch Directive
    

    

    Description:Sends an external redirect based on a regular expression match
of the current URL
    

    Syntax:RedirectMatch [status] regex
URL
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_alias
    

    
    
    This directive is equivalent to Redirect, but makes use of
    regular expressions,
    instead of simple prefix matching. The
    supplied regular expression is matched against the URL-path, and
    if it matches, the server will substitute any parenthesized
    matches into the given string and use it as a filename. For
    example, to redirect all GIF files to like-named JPEG files on
    another server, one might use:
    

    
    RedirectMatch "(.*)\.gif$" "http://other.example.com$1.jpg"
    


    
    The considerations related to the difference between
    Alias and
    AliasMatch
    also apply to the difference between
    Redirect and
    RedirectMatch.
    See AliasMatch for
    details.

    Module:mod_alias
    

    
    
    This directive makes the client know that the Redirect is
    permanent (status 301). Exactly equivalent to Redirect
    permanent.

    RedirectTemp Directive

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_alias
    

    
    
    This directive makes the client know that the Redirect is
    only temporary (status 302). Exactly equivalent to
    Redirect temp.

    ScriptAlias Directive
    

    

    Description:Maps a URL to a filesystem location and designates the
target as a CGI script
    

    Syntax:ScriptAlias [URL-path]
file-path|directory-path
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_alias
    

    
    
    The ScriptAlias directive has the same
    behavior as the Alias
    directive, except that in addition it marks the target directory
    as containing CGI scripts that will be processed by mod_cgi's cgi-script handler. URLs with a case-sensitive
    (%-decoded) path beginning with URL-path will be mapped
    to scripts beginning with the second argument, which is a full
    pathname in the local filesystem.
    

    
    ScriptAlias "/cgi-bin/" "/web/cgi-bin/"
    


    
    A request for http://example.com/cgi-bin/foo would cause the
    server to run the script /web/cgi-bin/foo.  This configuration
    is essentially equivalent to:
    
    
    Alias "/cgi-bin/" "/web/cgi-bin/"
<Location "/cgi-bin">
    SetHandler cgi-script
    Options +ExecCGI
</Location>
    


    
    ScriptAlias can also be used in conjunction with
    a script or handler you have. For example:
    

    
    ScriptAlias "/cgi-bin/" "/web/cgi-handler.pl"
    


    
    In this scenario all files requested in /cgi-bin/ will be
    handled by the file you have configured, this allows you to use your own custom
    handler.  You may want to use this as a wrapper for CGI so that you can add
    content, or some other bespoke action.
    

    
    It is safer to avoid placing CGI scripts under the
    DocumentRoot in order to
    avoid accidentally revealing their source code if the
    configuration is ever changed.  The
    ScriptAlias makes this easy by mapping a
    URL and designating CGI scripts at the same time.  If you do
    choose to place your CGI scripts in a directory already
    accessible from the web, do not use
    ScriptAlias.  Instead, use <Directory>, SetHandler, and Options as in:
    
    <Directory "/usr/local/apache2/htdocs/cgi-bin">
    SetHandler cgi-script
    Options ExecCGI
</Directory>
    

    This is necessary since multiple URL-paths can map
    to the same filesystem location, potentially bypassing the
    ScriptAlias and revealing the source code
    of the CGI scripts if they are not restricted by a
    Directory section.
    

    
    If the ScriptAlias directive is used within
    a <Location>
    or <LocationMatch>
    section with the URL-path omitted, then the URL parameter will be
    interpreted using expression syntax.
    
    This syntax is available in Apache 2.4.19 and later.
    

    
    <Location "/cgi-bin">
    ScriptAlias "/web/cgi-bin/"
</Location>
<LocationMatch "/cgi-bin/errors/(?<NUMBER>[0-9]+)">
    ScriptAlias "/web/cgi-bin/errors/%{env:MATCH_NUMBER}.cgi"
</LocationMatch>

    ScriptAliasMatch Directive
    

    

    Description:Maps a URL to a filesystem location using a regular expression
and designates the target as a CGI script
    

    Syntax:ScriptAliasMatch regex
file-path|directory-path
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_alias
    

    
    
    This directive is equivalent to ScriptAlias, but makes use of
    regular expressions,
    instead of simple prefix matching. The
    supplied regular expression is matched against the URL-path,
    and if it matches, the server will substitute any parenthesized
    matches into the given string and use it as a filename. For
    example, to activate the standard /cgi-bin, one
    might use:
    

    
    ScriptAliasMatch "^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"
    


    
    As for AliasMatch, the full range of regular
    expression power is available.
    For example, it is possible to construct an alias with case-insensitive
    matching of the URL-path:
    

    
    ScriptAliasMatch "(?i)^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"
    


    
    The considerations related to the difference between
    Alias and
    AliasMatch
    also apply to the difference between
    ScriptAlias and
    ScriptAliasMatch.
    See AliasMatch for
    details.

    Fichier Source:mod_negotiation.c
    

    Sommaire
    

    
    La négociation de contenu, ou plus précisément la sélection de
    contenu, est la sélection parmi plusieurs documents disponibles, du
    document qui "colle" au plus près des possibilités du client. Pour y
    parvenir, deux méthodes sont employées.
    

    
      
      
    • Une table de correspondances de types (un fichier associé au
      gestionnaire type-map) qui contient une liste
      explicite des fichiers contenant les différentes variantes.
      • 

      
    • Une recherche multivues (Multiviews) (activée par l'Options Multiviews), où le
      serveur effectue une recherche de correspondance de modèle de nom
      de fichier implicite, et fait son choix parmi les résultats.
      • 
    
    

    


    top
    

    

    Tables de correspondances de types
    
    
    Une table de correspondances de types possède un format similaire
    à celui des en-têtes de messagerie RFC822. Elle contient des
    descriptions de documents séparées par des lignes vides, toute ligne
    commençant par un dièse ('#') étant considérée comme un
    commentaire. Une description de document comporte plusieurs
    enregistrements d'en-têtes ; chaque enregistrement peut être réparti
    sur plusieurs lignes à condition que les lignes supplémentaires
    commencent par un ou plusieurs espaces. Lors du traitement, les
    espaces de début de ligne seront supprimés et les lignes
    concaténées. L'enregistrement d'un en-tête comprend un mot-clé qui
    se termine toujours par un caractère "deux-points" ':', suivi d'une
    valeur. Les espaces sont autorisés entre le nom d'en-tête et sa
    valeur, ainsi qu'entre les différents éléments de la valeur. Les
    en-têtes autorisés sont :
    

    
    
      
    Content-Encoding:
    
      
    Le codage du fichier. Apache ne reconnaît que les codages
      définis par une directive AddEncoding. Sont normalement inclus
      les codages x-compress pour les fichiers compressés
      avec compress, et x-gzip pour les fichiers compressés
      avec gzip. Le préfixe x- est ignoré lors des
      comparaisons de codages.
    

      
    Content-Language:
    
      
    Le(s) langage(s) de la variante, sous la forme d'un symbole de
      langage Internet standard (RFC 1766). Par
      exemple, en correspond à l'anglais. Si la variante
      contient plusieurs langages, ils sont séparés par des
      virgules.
    

      
    Content-Length:
    
      
    La taille du fichier en octets. Si cet en-tête n'est pas
      présent, c'est la taille réelle du fichier qui est utilisée.
    

      
    Content-Type:
    

      
    
        Le type MIME du document
	avec des paramètres optionnels. Les paramètres sont séparés du
	type de médium ainsi qu'entre eux par un point-virgule, et
	possèdent la syntaxe nom=valeur. Les paramètres
	courants sont :

        
    
          
    level
    
          
    un entier spécifiant la version du type de média. Pour
	  text/html, la valeur par défaut est 2, sinon
	  0.
    

          
    qs
    
          
    un nombre en virgule flottante de 0[.000] à 1[.000], indiquant la
	  "qualité" relative de la variante courante par rapport aux
	  autres variantes disponibles, indépendamment des possibilités
	  du client. Par exemple, un fichier jpeg est en général une
	  source de qualité supérieure à un fichier ascii s'il est censé
	  représenter une image. Cependant, si la ressource représentée
	  est une image ascii, un fichier ascii possèdera une qualité
	  supérieure à un fichier jpeg. Toutes les valeurs de
	  qs sont donc spécifiques à une certaine
	  ressource.
    
        
    

        
    Exemple
    
          Content-Type: image/jpeg; qs=0.8
        
    
      
    

      
    URI:
    
      
    l'URI du fichier contenant la variante (du type de médium
      donné, codé selon le codage de contenu donné). Cet URI est
      considéré comme relatif au fichier de correspondances ; il doit
      être situé sur le même serveur, et doit faire référence au
      fichier auquel le client se verrait accorder l'accès s'il était
      requis directement.
    

      
    Body:
    
      
    Le contenu réel de la ressource
      peut être inclus dans la table de correspondances en utilisant
      l'en-tête Body. Cet en-tête doit contenir une chaîne désignant un
      délimiteur pour le contenu du corps. Les lignes suivantes du
      fichier de correspondances de types seront alors considérées comme
      parties du corps de la ressource jusqu'à ce que le délimiteur soit
      détecté.

      
    Exemple:
    
        Body:----xyz----
    
        <html>
    
        <body>
    
        <p>Contenu de la page.</p>
    
        </body>
    
        </html>
    
        ----xyz----
      
    
      
    
    
    

    
    Considérons une ressource, document.html, disponible
    en anglais, en français et en allemand. Les fichiers correspondants
    se nomment respectivement document.html.en,
    document.html.fr, et document.html.de. Le
    fichier de correspondances de types se nommera
    document.html.var et contiendra ce qui suit :
    

    
    
    URI: document.html
    
    
    
    Content-language: en
    
    Content-type: text/html
    
    URI: document.html.en
    
    
    
    Content-language: fr
    
    Content-type: text/html
    
    URI: document.html.fr
    
    
    
    Content-language: de
    
    Content-type: text/html
    
    URI: document.html.de
    
    
    

    
    

    
    Ces quatre fichiers doivent se trouver dans le même répertoire,
    et le fichier .var doit être associé au gestionnaire
    type-map via une directive AddHandler :
    

    
    AddHandler type-map .var
    


    
    A l'arrivée d'une requête pour la ressource
    document.html.var, la variante de
    document.html qui correspond le mieux à la préference
    de langage spécifiée dans l'en-tête de la requête de l'utilisateur
    Accept-Language sera choisie.
    

    
    Si Multiviews est activée, et si MultiviewsMatch est définie à
    "handlers" ou "any", une requête pour document.html va
    rechercher document.html.var, et continuer la
    négociation avec le gestionnaire explicite type-map.
    

    
    D'autres directives de configuration, comme Alias, peuvent être utilisées pour
    associer document.html avec
    document.html.var.
    

    top
    

    

    Multivues
    
    
    Une recherche Multivues est activée par l'Options Multiviews. Si le
    serveur reçoit une requête pour /un/répertoire/foo, et
    si /un/répertoire/foo n'existe pas, le serveur parcourt
    le répertoire à la recherche de tous les fichiers de nom
    foo.*, et simule véritablement une correspondance de
    type qui nomme tous ces fichiers en leur assignant les mêmes type
    de média et codage de contenu qu'ils auraient eus si le client avait
    requis l'un d'entre eux avec son nom complet. Il choisit ensuite le
    fichier qui correspond le mieux au profile du client, puis renvoie
    le document.
    

    
    La directive MultiviewsMatch définit si Apache doit
    prendre en compte les fichiers qui ne comportent pas de métadonnées
    de négociation de contenu lors du choix du fichier à servir.

    Directive CacheNegotiatedDocs
    

    

    Description:Permet la mise en cache au niveau des serveurs mandataires
des documents dont le contenu a été négocié
    

    Syntaxe:CacheNegotiatedDocs On|Off
    

    Défaut:CacheNegotiatedDocs Off
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_negotiation
    

    
    
    Si elle est définie à "on", cette directive permet la mise en
    cache au niveau des serveurs mandataires des documents dont le
    contenu a été négocié. Le processus de mise en cache sera alors plus
    efficace, mais des clients se trouvant derrière le mandataire
    seront alors susceptibles de se voir servir des versions de
    documents qui ne correspondent pas forcément à leurs attentes.
    

    
    Cette directive ne s'applique qu'aux requêtes en provenance de
    navigateurs HTTP/1.0. HTTP/1.1 fournit un bien meilleur contrôle de
    la mise en cache des documents au contenu négocié, et cette
    directive n'a aucun effet sur les réponses aux requêtes
    HTTP/1.1.

    Directive ForceLanguagePriority
    

    

    Description:Action à entreprendre si un document acceptable unique
n'est pas trouvé
    

    Syntaxe:ForceLanguagePriority None|Prefer|Fallback [Prefer|Fallback]
    

    Défaut:ForceLanguagePriority Prefer

    Statut:Base
    

    Module:mod_negotiation
    

    
    
    La directive ForceLanguagePriority utilise
    le langage défini par la directive LanguagePriority pour terminer
    la négociation lorsque le serveur n'est pas en mesure de trouver une
    solution satisfaisante unique.
    

    
    ForceLanguagePriority Prefer utilise la directive
    LanguagePriority pour servir le résultat d'un choix
    unique, au lieu de renvoyer un résultat HTTP 300 (MULTIPLE CHOICES),
    lorsque que plusieurs choix équivalents sont disponibles. Par
    exemple, avec les deux directives ci-dessous, si l'en-tête
    Accept-Language de l'utilisateur assigne à
    en et de une qualité de .500
    (les deux langages sont également acceptables), alors c'est la
    première variante acceptable de langue en qui sera
    servie.
    

    
    LanguagePriority en fr de
ForceLanguagePriority Prefer
    


    
    ForceLanguagePriority Fallback utilise la directive
    LanguagePriority
    pour servir un résultat valide, au lieu de renvoyer un résultat HTTP
    406 (NOT ACCEPTABLE). Avec les deux directives ci-dessous, si
    l'en-tête Accept-Language de l'utilisateur ne mentionne
    que les réponses de langage es, et si aucune variante
    dans cette langue n'est trouvée, c'est la première variante de la
    liste définie par la directive LanguagePriority qui sera servie.
    

    
    LanguagePriority en fr de
ForceLanguagePriority Fallback
    


    
    Les deux options, Prefer et Fallback,
    peuvent être spécifiées, de façon à ce que la variante servie soit
    la première variante qui convient définie par la directive
    LanguagePriority si
    plusieurs variantes sont également acceptables, ou le premier
    document disponible si aucune variante ne convient à la liste de
    langages acceptables fournie par le client.

    La directive LanguagePriority permet de
    définir, au cours du traitement d'une requête Multivues, l'ordre de
    priorité des variantes de langages pour les cas
    où le client n'a pas formulé de préférences. La liste énumère les
    langages-MIME dans un ordre de préférences
    décroissantes.

    foo.html.fr et foo.html.de existent, et si
    le client n'a pas formulé de préférences, c'est le fichier
    foo.html.fr qui sera renvoyé.
    

    
    Notez que cette directive n'a d'effet que si le 'meilleur'
    langage n'a pas pu être déterminé d'une autre manière ou si la
    valeur de la directive  ForceLanguagePriority est
    différente de None. En général, c'est le client qui
    détermine le langage préféré, non le serveur.

    説明:認証が必要な領域への "anonymous" ユーザのアクセスを許可する

    概要
    

    
    このモジュールは mod_auth_basic のような
    認証フロントエンドとして、anonymous-ftp サイトのような、「魔法の」ユーザ ID
    'anonymous' と電子メールアドレスをパスワードにしたユーザ認証を
    行なう機能を提供します。この電子メールアドレスはログ収集することが
    できます。
    

    
    他の (データベースによる) アクセス制御方法と組み合わせることで、
    「未登録」ユーザに対してサイトを公開しつつ、効率よくユーザ追跡したり、
    ユーザのプロファイルに応じたカスタマイズをしたりできます。
    このような認証に基づいたユーザ追跡の利点の一つは、
    マジッククッキーに基づくユーザ追跡方法や、
    珍妙な URL の接頭辞や接尾辞を利用したユーザ追跡方法とは異なり、
    完全にブラウザ非依存であり、ユーザ間で URL を共有することができるという
    点です。
    

    
    mod_auth_basic を使用している場合は、このモジュールは
    AuthBasicProvider に
    anon という値を設定することで起動されます。

    例
    
    
    以下の例は「普通」の htpasswd ファイルに基づいた認証と組み合わされて
    おり、以下の要件を見たすユーザを「ゲスト」として許可します:
    

    
      
      
    • ユーザは userID を入力しなければなりません。

      • 

      
    • ユーザはパスワードを入力しなければなりません。
      (Anonymous_MustGiveEmail)

    Module Apache mod_cgid
    

    

    Langues Disponibles:  en  |

    Description:Exécution des scripts CGI par l'intermédiaire d'un démon
CGI externe
    

    Statut:Base
    

    Identificateur de Module:cgid_module
    

    Fichier Source:mod_cgid.c
    

    Compatibilité:Uniquement compatible avec les MPMs Unix
threadés
    

    Sommaire
    

    
    Exceptées les optimisations et la directive additionnelle
    ScriptSock décrite
    ci-dessous, mod_cgid a un comportement similaire à
    celui de mod_cgi. Voir le résumé de
    mod_cgi pour plus de détails à propos d'Apache et
    CGI.
    

    
    Sur certains systèmes d'exploitation de type unix, le lancement
    (forking) d'un processus depuis un serveur multi-threadé est une
    opération très lourde car le nouveau processus va répliquer tous les
    threads du processus parent. Pour éviter cette dépense de ressouces
    pour chaque invocation d'un programme CGI, mod_cgid
    crée un démon externe qui est responsable du branchement de
    processus enfants destinés au lancement de scripts CGI. Le serveur
    principal communique avec ce démon par l'intermédiaire d'une socket
    de domaine unix.
    

    
    Si un MPM multi-threadé a été sélectionné lors du processus de
    compilation, c'est ce module qui est utilisé par défaut à la place
    de mod_cgi. Du point de vue de l'utilisateur, ce
    module est identique à mod_cgi quant à sa
    configuration et son utilisation. La seule différence est la
    directive additionnelle ScriptSock qui permet de
    définir le nom du socket à utiliser pour la communication avec le
    démon CGI.
    

    



    top
    

    Directive CGIDScriptTimeout
    

    

    Description:Durée maximale d'attente de la prochaine sortie du
programme CGI
    

    Syntaxe:CGIDScriptTimeout time[s|ms]
    

    Défaut:Si non définie ou définie à 0, valeur de la directive Timeout
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Statut:Base
    

    Module:mod_cgid
    

    Compatibilité:Disponible à partir de la version 2.4.10 du serveur HTTP Apache ;
dans les versions précédentes, aucune durée d'attente n'était définie
    

    
    
    Cette directive permet de limiter la durée d'attente avant les prochaines données
    reçues en sortie du programme CGI. Si ce temps est dépassé, la requête et le
    programme CGI se terminent.
    

    
    Exemple
    CGIDScriptTimeout 20
    

    



    

    top
    

    Directive ScriptSock
    

    

    Description:Le préfixe du nom de fichier du socket à utiliser pour
communiquer avec le démon CGI
    

    Syntaxe:ScriptSock chemin fichier
    

    Défaut:ScriptSock cgisock
    

    Contexte:configuration globale
    

    Statut:Base
    

    Module:mod_cgid
    

    
    
    Cette directive permet de définir le préfixe du nom de fichier de la
    socket à utiliser pour communiquer avec le démon CGI, préfixe auquel
    sera ajouté une extension correspondant à l'identifiant processus du
    serveur. La socket sera ouverte avec les permissions de l'utilisateur
    qui a démarré Apache (en général root). Afin de préserver la
    sécurité des communications avec les scripts CGI, il est impératif
    de n'accorder à aucun autre utilisateur la permission d'écrire dans
    le répertoire où se trouve la socket.
    

    
    Si chemin fichier n'est pas un chemin absolu, il est
    relatif au chemin défini par la directive DefaultRuntimeDir.
    

    
    Exemple
    ScriptSock /var/run/cgid.sock

    Module Apache mod_isapi
    

    

    Langues Disponibles:  en  |

    Description:Extensions ISAPI dans Apache pour Windows
    

    Statut:Base
    

    Identificateur de Module:isapi_module
    

    Fichier Source:mod_isapi.c
    

    Compatibilité:Win32 only
    

    Sommaire
    

    
    Ce module implémente l'API des extensions du Serveur Internet. Il
    permet à Apache pour Windows de servir les extensions du Serveur
    Internet (par exemple les modules .dll ISAPI), compte tenu des
    restrictions spécifiées.
    

    
    Les modules d'extension ISAPI (fichiers .dll) sont des modules
    tiers. Leur auteur n'est pas le Groupe Apache, et nous n'assurons
    donc pas leur support. Veuillez contacter directement l'auteur
    d'ISAPI si vous rencontrez des problèmes à l'exécution d'une
    extension ISAPI. Merci de ne pas soumettre ce genre
    de problème dans les listes d'Apache ou dans les pages de rapports
    de bogues.
    

    


    top
    

    

    Utilisation
    

    
    Dans le fichier de configuration du serveur, utilisez la
    directive AddHandler pour
    associer les fichiers ISAPI au gestionnaire
    isapi-handler à l'aide de l'extension de leur nom de
    fichier. Pour faire en sorte que tout fichier .dll soit traité en
    tant qu'extension ISAPI, éditez le fichier httpd.conf et ajoutez les
    lignes suivantes :
    
    
    AddHandler isapi-handler .dll
    


    
    Dans les versions plus anciennes du serveur Apache, le nom du
    gestionnaire était isapi-isa au lieu de
    isapi-handler. Depuis les versions de développement 2.3
    du serveur Apache, isapi-isa n'est plus valide, et vous
    devrez éventuellement modifier votre configuration pour utiliser
    isapi-handler à la place.
    

    
    Le serveur Apache ne propose aucun moyen de conserver en mémoire
    un module chargé. Vous pouvez cependant précharger et garder un
    module spécifique en mémoire en utilisant la syntaxe suivante dans
    votre httpd.conf :
    
    
    ISAPICacheFile c:/WebWork/Scripts/ISAPI/mytest.dll
    


    
    Que vous ayez ou non préchargé une extension ISAPI, ces dernières
    sont toutes soumises au mêmes restrictions et possèdent les mêmes
    permissions que les scripts CGI. En d'autres termes, Options ExecCGI doit être
    défini pour le répertoire qui contient le fichier .dll ISAPI.
    

    
    Reportez-vous aux Notes additionnelles et au
    Journal du programmeur pour plus de détails
    et une clarification à propos du support spécifique ISAPI fourni par
    le module mod_isapi.
    

    top
    

    

    Notes additionnelles
    

    
    L'implémentation ISAPI d'Apache se conforme à toutes les
    spécifications ISAPI 2.0, à l'exception de certaines extensions
    "spécifiques Microsoft" utilisant des entrées/sorties asynchrones.
    Le modèle des entrées/sorties d'Apache ne permet pas l'écriture et
    la lecture asynchrone de la manière dont ISAPI pourrait le faire. Si
    une extension tente d'utiliser des fonctionnalités non supportées,
    comme les entrées/sorties asynchrones, un message est enregistré
    dans le journal des erreurs afin d'aider au débogage. Comme ces
    messages peuvent devenir envahissants, la directive
    ISAPILogNotSupported Off permet de filter ce bruit de
    fond.
    

    
    Si aucune option de configuration particulière n'est spécifiée,
    certains serveurs, comme Microsoft IIS, chargent l'extension ISAPI
    dans le serveur et la conservent en mémoire jusqu'à ce que
    l'utilisation de cette dernière devienne trop élevée. Apache, par
    contre, charge et décharge réellement l'extension ISAPI chaque fois
    qu'elle est invoquée, si la directive ISAPICacheFile n'a pas été spécifiée.
    Ce n'est pas très performant, mais le modèle de mémoire d'Apache
    fait que cette méthode est la plus efficace. De nombreux modules
    ISAPI présentent des incompatibilités subtiles avec le serveur
    Apache, et le déchargement de ces modules permet d'assurer la
    stabilité du serveur.
    

    
    En outre, gardez à l'esprit que si Apache supporte les extensions
    ISAPI, il ne supporte pas les filtres ISAPI. Le
    support des filtres sera peut-être ajouté dans le futur, mais n'a
    pas encore été planifié.
    

    top
    

    

    Journal du programmeur
    

    
    Si vous écrivez des modules mod_isapi Apache
    2.0, vous devez limiter vos appels à
    ServerSupportFunction aux directives suivantes :
    

    
    
      
    HSE_REQ_SEND_URL_REDIRECT_RESP
    
      
    Redirige l'utilisateur vers une autre adresse.
    
      Il doit s'agir d'une URL pleinement qualifiée (comme
      http://serveur/chemin).
    

      
    HSE_REQ_SEND_URL
    
      
    Redirige l'utilisateur vers une autre adresse.
    
      Ce ne doit pas être une URL pleinement qualifiée ; la mention du
      protocole ou du nom du serveur n'est pas autorisée (par exemple,
      utilisez simplement /chemin).
    
      La redirection n'est pas assurée par le navigateur mais par le
      serveur lui-même.
    
      
    Avertissement
    
        
    Dans sa documentation récente, Microsoft semble avoir
	abandonné la distinction entre les deux fonctions
	HSE_REQ_SEND_URL. Apache, quant à lui, continue de
	les traiter comme deux fonctions distinctes avec des contraintes
	et des comportements spécifiques.
    
      
    

      
    HSE_REQ_SEND_RESPONSE_HEADER
    
      
    Apache accepte un corps de réponse après l'en-tête s'il se
      situe après la ligne vide (deux caractères newline consécutifs)
      dans la chaîne des arguments d'en-têtes. Ce corps ne doit pas
      contenir de caractères NULL, car l'argument des en-têtes est
      lui-même terminé par un caractère NULL.
    

      
    HSE_REQ_DONE_WITH_SESSION
    
      
    Apache considère ceci comme sans objet, car la session est
      fermée lorsque l'extension ISAPI termine son traitement.
    

      
    HSE_REQ_MAP_URL_TO_PATH
    
      
    Apache va traduire un nom virtuel en nom physique.
    

      
    HSE_APPEND_LOG_PARAMETER
    
      
    
        Ce paramètre peut intervenir dans un de ces journaux :

        

        
    La première option, le composant
	%{isapi-parameter}n, est préférable et toujours
	disponible.
    
      
    

      
    HSE_REQ_IS_KEEP_CONN
    
      
    retourne le statut négocié Keep-Alive.
    

      
    HSE_REQ_SEND_RESPONSE_HEADER_EX
    
      
    se comportera comme indiqué dans le documentation, bien que le
      drapeau fKeepConn soit ignoré.
    

      
    HSE_REQ_IS_CONNECTED
    
      
    renverra faux si la requête a été abandonnée.
    
    
    

    
    Apache renvoie FALSE pour tout appel non supporté à
    ServerSupportFunction, et GetLastError
    renverra la valeur ERROR_INVALID_PARAMETER.
    

    
    ReadClient extrait la partie du corps de la requête
    qui dépasse le tampon initial (défini par la directive ISAPIReadAheadBuffer). En fonction de
    la définition de la directive
    ISAPIReadAheadBuffer (nombre d'octets à
    mettre dans le tampon avant d'appeler le gestionnaire ISAPI), les
    requêtes courtes sont envoyées en entier à l'extension lorsque
    celle-ci est invoquée. Si la taille de la requête est trop
    importante, l'extension ISAPI doit faire appel à
    ReadClient pour extraire la totalité du corps de la
    requête.
    

    
    WriteClient est supporté, mais seulement avec le
    drapeau HSE_IO_SYNC ou le drapeau "aucune option"
    (valeur 0). Toute autre requête
    WriteClient sera rejetée avec une valeur de retour
    FALSE, et GetLastError renverra la valeur
    ERROR_INVALID_PARAMETER
    

    
    GetServerVariable est supporté, bien que les
    variables étendues de serveur n'existent pas (comme défini par
    d'autres serveurs). Toutes les variables d'environnement CGI
    usuelles d'Apache sont disponibles à partir de
    GetServerVariable, ainsi que les valeurs
    ALL_HTTP et ALL_RAW.
    

    
    Depuis httpd 2.0, mod_isapi propose des
    fonctionnalités supplémentaires introduites dans les versions
    actualisées de la spécification ISAPI, ainsi qu'une émulation
    limitée des entrées/sorties asynchrones et la sémantique
    TransmitFile. Apache httpd supporte aussi le préchargement
    des .dlls ISAPI à des fins de performances.

    Description:Autorisation basée sur l'appartenance des
fichiers
    

    Statut:Extension
    

    Identificateur de Module:authz_owner_module
    

    Fichier Source:mod_authz_owner.c
    

    Compatibilité:Disponible depuis les versions 2.1 et supérieures
d'Apache
    

    Sommaire
    

    
    Ce module permet de contrôler l'accès aux fichiers en comparant
    l'identifiant utilisateur ayant servi à l'authentification HTTP
    (l'identifiant utilisateur web) avec le propriétaire ou le groupe
    du fichier demandé du point de vue du système de fichiers. Le nom
    d'utilisateur et le mot de passe doivent déjà avoir été vérifiés par
    un module d'authentification comme mod_auth_basic
    ou mod_auth_digest.
    mod_authz_owner reconnaît deux arguments pour la
    directive Require :
    file-owner et file-group :
    

    
    
      
    file-owner
    
      
    Le nom d'utilisateur web utilisé pour l'authentification doit
      correspondre au nom système du propriétaire du fichier demandé. En
      d'autres termes, si le système indique jones comme
      propriétaire du fichier demandé, le nom d'utilisateur fourni pour
      l'authentification HTTP doit aussi être jones.
    

      
    file-group
    
      
    Le nom du groupe système du fichier demandé doit être présent
      dans une base de données de groupes fournie, par exemple, par
      mod_authz_groupfile ou
      mod_authz_dbm, et le nom d'utilisateur web fourni
      pour l'authentification doit être un membre de ce groupe. Par
      exemple, si le système indique que le groupe (système) du fichier
      demandé est accounts, le groupe accounts
      doit apparaître dans la base de données des groupes, et le nom
      d'utilisateur web utilisé pour l'authentification doit être un
      membre de ce groupe.
    
    
    

    
    Note
    
      
    Si le module mod_authz_owner est utilisé pour
      vérifier l'autorisation d'accès à une ressource qui n'est pas
      vraiment présente dans le système de fichiers (en d'autres termes
      une ressource virtuelle), il refusera l'accès.
    

      
    En particulier, il n'accordera jamais l'accès à une ressource
      du type "Vues
      multiples" (MultiViews) d'un contenu négocié.

    Exemples de configuration
    

    
    Require file-owner
    
      
    Considérons un serveur Web Apache fonctionnant sous un système
      multi-utilisateurs, où les fichiers de chaque utilisateur sont
      stockés dans ~/public_html/private. En supposant
      qu'il n'existe qu'une seule base de données contenant les noms
      d'utilisateurs web, et que ces noms d'utilisateurs correspondent
      aux noms d'utilisateurs système qui sont les propriétaires
      effectifs des fichiers, la configuration de l'exemple suivant
      n'accordera l'autorisation d'accès aux fichiers qu'à leur
      propriétaire. L'utilisateur jones ne sera pas
      autorisé à accéder aux fichiers situés dans
      /home/smith/public_html/private, à moins que leur
      propriétaire ne soit jones au lieu de
      smith.
    

      
    <Directory "/home/*/public_html/private">
    AuthType Basic
    AuthName MyPrivateFiles
    AuthBasicProvider dbm
    AuthDBMUserFile "/usr/local/apache2/etc/.htdbm-all"
    Require file-owner
</Directory>
    

    

    
    Require file-group
    
      
    Considérons un système similaire à celui décrit ci-dessus, mais
      où certains utilisateurs partagent leurs fichiers de projets dans
      ~/public_html/project-foo. Le groupe système des
      fichiers est foo, et il n'existe qu'une seule base de
      données AuthDBMGroupFile qui contient
      tous les noms d'utilisateurs web et leurs groupes d'appartenance.
      Ces noms d'utilisateurs web doivent alors appartenir au moins au
      groupe foo. En d'autres termes, si jones
      et smith sont tous deux membres du groupe
      foo, ils seront autorisés à accéder aux
      répertoires project-foo de chacun d'entre eux.
    

      
    <Directory "/home/*/public_html/project-foo">
    AuthType Basic
    AuthName "Project Foo Files"
    AuthBasicProvider dbm
    
    # combined user/group database
    AuthDBMUserFile  "/usr/local/apache2/etc/.htdbm-all"
    AuthDBMGroupFile "/usr/local/apache2/etc/.htdbm-all"
    
    Satisfy All
    Require file-group
</Directory>

    Description:Manages a cache of authentication credentials to relieve

    Status:Base
    

    Module Identifier:authn_socache_module
    

    Source File:mod_authn_socache.c
    

    Compatibility:Version 2.3 and later
    

    Summary
    

    
    Maintains a cache of authentication credentials, so that a new backend
    lookup is not required for every authenticated request.
    

    


    top
    

    

    Authentication Caching
    
    
    Some users of more heavyweight authentication such as SQL database
    lookups (mod_authn_dbd) have reported it putting an
    unacceptable load on their authentication provider.  A typical case
    in point is where an HTML page contains hundreds of objects
    (images, scripts, stylesheets, media, etc), and a request to the page
    generates hundreds of effectively-immediate requests for authenticated
    additional contents.
    
    
    mod_authn_socache provides a solution to this problem by
    maintaining a cache of authentication credentials.
    

    top
    

    

    Usage
    
    
    The authentication cache should be used where authentication
    lookups impose a significant load on the server, or a backend or
    network.  Authentication by file (mod_authn_file)
    or dbm (mod_authn_dbm) are unlikely to benefit,
    as these are fast and lightweight in their own right (though in some
    cases, such as a network-mounted file, caching may be worthwhile).
    Other providers such as SQL or LDAP based authentication are more
    likely to benefit, particularly where there is an observed
    performance issue.  Amongst the standard modules, mod_authnz_ldap manages its own cache, so only
    mod_authn_dbd will usually benefit from this cache.
    
    
    The basic rules to cache for a provider are:
    
    
    1. Include the provider you're caching for in an
            AuthnCacheProvideFor directive.
      2. 
        
    2. List socache ahead of the provider you're
            caching for in your AuthBasicProvider or AuthDigestProvider directive.
      3. 
    
    
    
    A simple usage example to accelerate mod_authn_dbd
    using dbm as a cache engine:
    
    
    #AuthnCacheSOCache is optional.  If specified, it is server-wide
AuthnCacheSOCache dbm
<Directory "/usr/www/myhost/private">
    AuthType Basic
    AuthName "Cached Authentication Example"
    AuthBasicProvider socache dbd
    AuthDBDUserPWQuery "SELECT password FROM authn WHERE user = %s"
    AuthnCacheProvideFor dbd
    Require valid-user
    #Optional
    AuthnCacheContext dbd-authn-example
</Directory>
    


    top
    

    

    Caching with custom modules
    
    
    Module developers should note that their modules must be enabled
    for caching with mod_authn_socache.  A single optional API function
    ap_authn_cache_store is provided to cache credentials
    a provider has just looked up or generated.  Usage examples are
    available in r957072, in which three authn providers are enabled for caching.
    

    

    top
    

    AuthnCacheContext Directive
    

    

    Description:Specify a context string for use in the cache key
    

    Syntax:AuthnCacheContext directory|server|custom-string
    

    Default:AuthnCacheContext directory
    

    Context:directory
    

    Status:Base
    

    Module:mod_authn_socache
    

    
    
    This directive specifies a string to be used along with the supplied
    username (and realm in the case of Digest Authentication) in constructing
    a cache key.  This serves to disambiguate identical usernames serving
    different authentication areas on the server.
    
    
    Two special values for this are directory, which uses
    the directory context of the request as a string, and server
    which uses the virtual host name.
    
    
    The default is directory, which is also the most
    conservative setting.  This is likely to be less than optimal, as it
    (for example) causes $app-base, $app-base/images,
    $app-base/scripts and $app-base/media each to
    have its own separate cache key.  A better policy is to name the
    AuthnCacheContext for the password
    provider: for example a htpasswd file or database table.
    
    
    Contexts can be shared across different areas of a server, where
    credentials are shared.  However, this has potential to become a vector
    for cross-site or cross-application security breaches, so this directive
    is not permitted in .htaccess contexts.
    


    

    top
    

    AuthnCacheEnable Directive
    

    

    Description:Enable Authn caching configured anywhere
    

    Syntax:AuthnCacheEnable
    

    Context:server config
    

    Status:Base
    

    Module:mod_authn_socache
    

    
    
    This directive is not normally necessary: it is implied if
    authentication caching is enabled anywhere in httpd.conf.
    However, if it is not enabled anywhere in httpd.conf
    it will by default not be initialised, and is therefore not
    available in a .htaccess context.  This directive
    ensures it is initialised so it can be used in .htaccess.
    


    

    top
    

    AuthnCacheProvideFor Directive
    

    

    Description:Specify which authn provider(s) to cache for
    

    Syntax:AuthnCacheProvideFor authn-provider [...]
    

    Default:None
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authn_socache
    

    
    
    This directive specifies an authentication provider or providers
    to cache for.  Credentials found by a provider not listed in an
    AuthnCacheProvideFor directive will not be cached.
    

    
    For example, to cache credentials found by mod_authn_dbd
    or by a custom provider myprovider, but leave those looked
    up by lightweight providers like file or dbm lookup alone:
    
    
    AuthnCacheProvideFor dbd myprovider
    



    

    top
    

    AuthnCacheSOCache Directive
    

    

    Description:Select socache backend provider to use
    

    Syntax:AuthnCacheSOCache provider-name[:provider-args]
    

    Context:server config
    

    Status:Base
    

    Module:mod_authn_socache
    

    Compatibility:Optional provider arguments are available in
Apache HTTP Server 2.4.7 and later
    

    
    
    This is a server-wide setting to select a provider for the
    shared object cache, followed by
    optional arguments for that provider.
    Some possible values for provider-name are "dbm", "dc",
    "memcache", or "shmcb", each subject to the appropriate module
    being loaded.  If not set, your platform's default will be used.
    


    

    top
    

    AuthnCacheTimeout Directive
    

    

    Description:Set a timeout for cache entries
    

    Syntax:AuthnCacheTimeout timeout (seconds)
    

    Default:AuthnCacheTimeout 300 (5 minutes)
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authn_socache
    

    
    
    Caching authentication data can be a security issue, though short-term
    caching is unlikely to be a problem.  Typically a good solution is to
    cache credentials for as long as it takes to relieve the load on a
    backend, but no longer, though if changes to your users and passwords
    are infrequent then a longer timeout may suit you.  The default 300
    seconds (5 minutes) is both cautious and ample to keep the load
    on a backend such as dbd (SQL database queries) down.
    
    
    This should not be confused with session timeout, which is an
    entirely separate issue.  However, you may wish to check your
    session-management software for whether cached credentials can
    "accidentally" extend a session, and bear it in mind when setting
    your timeout.

    Apache Module mod_authn_file
    

    

    Available Languages:  en  |

    Description:User authentication using text files
    

    Status:Base
    

    Module Identifier:authn_file_module
    

    Source File:mod_authn_file.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module provides authentication front-ends such as
    mod_auth_digest and mod_auth_basic
    to authenticate users by looking up users in plain text password files.
    Similar functionality is provided by mod_authn_dbm.
    

    
    When using mod_auth_basic or
    mod_auth_digest, this module is invoked via the
    AuthBasicProvider or
    AuthDigestProvider
    with the file value.

    AuthUserFile Directive
    

    

    Description:Sets the name of a text file containing the list of users and
passwords for authentication
    

    Syntax:AuthUserFile file-path
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authn_file
    

    
    
    The AuthUserFile directive sets the name
    of a textual file containing the list of users and passwords for
    user authentication. File-path is the path to the user
    file. If it is not absolute, it is treated as relative to the
    ServerRoot.
    

    
    Each line of the user file contains a username followed by
    a colon, followed by the encrypted password. If the same user
    ID is defined multiple times, mod_authn_file will
    use the first occurrence to verify the password.
    

    
    The encrypted password format depends on which authentication
    frontend (e.g. mod_auth_basic or
    mod_auth_digest) is being used.  See Password Formats for
    more information.
    

    
    For mod_auth_basic, use the utility htpasswd
    which is installed as part of the binary distribution, or which
    can be found in src/support. See the
    man page for more details.
    In short:
    

    
    Create a password file Filename with
    username as the initial ID. It will prompt for
    the password:
    

    
    
      htpasswd -c Filename username
    
    

    
    Add or modify username2 in the password file
    Filename:
    

    
    
      htpasswd Filename username2
    
    

    
    Note that searching large text files is very
    inefficient; AuthDBMUserFile should be used
    instead.
    

    
    For mod_auth_digest, use htdigest
    instead. Note that you cannot mix user data for Digest Authentication
    and Basic Authentication within the same file.
    

    
    Security
    
      
    Make sure that the AuthUserFile is
      stored outside the document tree of the web-server. Do
      not put it in the directory that it protects.
      Otherwise, clients may be able to download the
      AuthUserFile.

    Status:Extension

    Compatibility:Available in version 2.4.17 and later
    

    Summary
    

        
    This module provides HTTP/2 (RFC 7540) 
        support for the Apache HTTP Server.
    
        
        
    This module relies on libnghttp2
        to provide the core http/2 engine.
    
        
        
    You must enable HTTP/2 via Protocols
        in order to use the functionality described in this document. The
        HTTP/2 protocol does not require the use of encryption so two schemes are available:
        h2 (HTTP/2 over TLS) and h2c (HTTP/2 over TCP).
    

        
    Two useful configuration schemes are:
    
        
        
    HTTP/2 in a VirtualHost context (TLS only)
    
        
    Protocols h2 http/1.1
    

        
    Allows HTTP/2 negotiation (h2) via TLS ALPN in a secure
        <VirtualHost>.
        HTTP/2 preamble checking (Direct mode, see H2Direct) is disabled by default for h2.
    
        
    

        
    HTTP/2 in a Server context (TLS and cleartext)
    
        
    Protocols h2 h2c http/1.1
    

        
    Allows HTTP/2 negotiation (h2) via TLS ALPN for secure
        <VirtualHost>. Allows
        HTTP/2 cleartext negotiation (h2c) upgrading from an initial HTTP/1.1
        connection or via HTTP/2 preamble checking (Direct mode, see
        H2Direct).
    
        
    

        
    Refer to the official HTTP/2 FAQ
        for any doubt about the protocol.

    How it works
    
    
    
    HTTP/2 Dimensioning
    
        
    
            Enabling HTTP/2 on your Apache Server has impact on the resource
            consumption and if you have a busy site, you may need to consider
            carefully the implications.
        
    
        
    
            The first noticeable thing after enabling HTTP/2 is that your server
            processes will start additional threads. The reason for this is that
            HTTP/2 gives all requests that it receives to its own Worker
            threads for processing, collects the results and streams them out
            to the client.
        
    
        
    
            In the current implementation, these workers use a separate thread
            pool from the MPM workers that you might be familiar with. This is
            just how things are right now and not intended to be like this forever.
            (It might be forever for the 2.4.x release line, though.) So, HTTP/2
            workers, or shorter H2Workers, will not show up in mod_status. They
            are also not counted against directives such as ThreadsPerChild. However
            they take ThreadsPerChild
            as default if you have not configured something
            else via H2MinWorkers and
            H2MaxWorkers.
        
    
        
    
            Another thing to watch out for is is memory consumption. Since HTTP/2
            keeps more state on the server to manage all the open request, priorities
            for and dependencies between them, it will always need more memory
            than HTTP/1.1 processing. There are three directives which steer the
            memory footprint of a HTTP/2 connection:
            H2MaxSessionStreams,
            H2WindowSize and
            H2StreamMaxMemSize.
        
    
        
    
            H2MaxSessionStreams limits the
            number of parallel requests that a client can make on a HTTP/2 connection.
            It depends on your site how many you should allow. The default is 100 which
            is plenty and unless you run into memory problems, I would keep it this
            way. Most requests that browsers send are GETs without a body, so they
            use up only a little bit of memory until the actual processing starts.
        
    
        
    
            H2WindowSize controls how much
            the client is allowed to send as body of a request, before it waits
            for the server to encourage more. Or, the other way around, it is the
            amount of request body data the server needs to be able to buffer. This
            is per request.
        
    
        
    
            And last, but not least, H2StreamMaxMemSize
            controls how much response data shall be buffered. The request sits in
            a H2Worker thread and is producing data, the HTTP/2 connection tries
            to send this to the client. If the client does not read fast enough,
            the connection will buffer this amount of data and then suspend the
            H2Worker.
        
    
    
    
    
    Multiple Hosts and Misdirected Requests
    
        
    
            Many sites use the same TLS certificate for multiple virtual hosts. The 
            certificate either has a wildcard name, such as '*.example.org' or carries
            several alternate names. Browsers using HTTP/2 will recognize that and reuse
            an already opened connection for such hosts.
        
    
        
    
            While this is great for performance, it comes at a price: such vhosts 
            need more care in their configuration. The problem is that you will have
            multiple requests for multiple hosts on the same TLS connection. And that
            makes renegotiation impossible, in face the HTTP/2 standard forbids it.
        
    
        
    
            So, if you have several virtual hosts using the same certificate and
            want to use HTTP/2 for them, you need to make sure that all vhosts have
            exactly the same SSL configuration. You need the same protocol, 
            ciphers and settings for client verification.
        
    
        
    
            If you mix things, Apache httpd will detect it and return a special
            response code, 421 Misdirected Request, to the client.

    H2CopyFiles Directive
    

    

    Description:Determine file handling in responses

                This directive influences how file content is handled in
                responses. When off, which is the default, file handles
                are passed from the requestion processing down to the main
                connection, using the usual Apache setaside handling for
                managing the lifetime of the file.
            
    
            
    
                When set to on, file content is copied while the
                request is still being processed and the buffered data is passed
                on to the main connection. This is better if a third party
                module is injecting files with different lifetimes into the response. 
            
    
            
    
                An example for such a module is mod_wsgi that may place
                Python file handles into the response. Those files get close down when
                Python thinks processing has finished. That may be well before
                mod_http2 is done with them.

    H2Direct Directive

                This directive toggles the usage of the HTTP/2 Direct Mode. This
                should be used inside a 
                <VirtualHost> 
                section to enable direct HTTP/2 communication for that virtual host. 
            
    
            
    
                Direct communication means that if the first bytes received by the 
                server on a connection match the HTTP/2 preamble, the HTTP/2
                protocol is switched to immediately without further negotiation.
                This mode is defined in RFC 7540 for the cleartext (h2c) case. Its
                use on TLS connections not mandated by the standard.
            
    
            
    
                When a server/vhost does not have h2 or h2c enabled via
                Protocols,
                the connection is never inspected for a HTTP/2 preamble.
                H2Direct
                does not matter then. This is important for connections that
                use protocols where an initial read might hang indefinitely, such
                as NNTP.
            
    
            
    
                For clients that have out-of-band knowledge about a server
                supporting h2c, direct HTTP/2 saves the client from having to
                perform an HTTP/1.1 upgrade, resulting in better performance
                and avoiding the Upgrade restrictions on request bodies.
            
    
            
    
                This makes direct h2c attractive for server to server communication
                as well, when the connection can be trusted or is secured by other means.

                This setting controls if HTTP status 103 interim responses are
                forwarded to the client or not. By default, this is currently 
                not the case since a range of clients still have trouble with
                unexpected interim responses.
            
    
            
    
                When set to on, PUSH resources announced with
                H2PushResource will trigger an interim 103 response
                before the final response. The 103 response will carry Link
                headers that advise the preload of such resources.

                This directive toggles the security checks on HTTP/2 connections
                in TLS mode (https:). This can be used server wide or for specific
                <VirtualHost>s. 
            
    
            
    
                The security checks require that the TSL protocol is at least
                TLSv1.2 and that none of the ciphers listed in RFC 7540, Appendix A
                is used. These checks will be extended once new security requirements
                come into place.
            
    
            
    
                The name stems from the 
                Security/Server Side TLS
                definitions at mozilla where "modern compatibility" is defined. Mozilla Firefox and
                other browsers require modern compatibility for HTTP/2 connections. As everything
                in OpSec, this is a moving target and can be expected to evolve in the future.
            
    
            
    
                One purpose of having these checks in mod_http2 is to enforce this
                security level for all connections, not only those from browsers. The other
                purpose is to prevent the negotiation of HTTP/2 as a protocol should
                the requirements not be met.
            
    
            
    
                Ultimately, the security of the TLS connection is determined by the
                server configuration directives for mod_ssl.

                The option 'H2OutputBuffering on/off' controls the buffering of stream output.
                The default is on, which is the behaviour of previous versions. When off, all
                bytes are made available immediately to the main connection for sending them
                out to the client. This fixes interop issues with certain flavours of gRPC.

    Compatibility:Available in version 2.4.39 and later.
    

    
            
    
                With the default 0, no padding bytes are added to any payload
                frames, e.g. HEADERS, DATA and PUSH_PROMISE. This is the behaviour
                of previous versions. It means that under certain conditions, an
                observer of network traffic can see the length of those frames 
                in the TLS stream.
            
    
            
    
                When configuring numbits of 1-8, a random number in range
                [0, 2^numbits[ are added to each frame. The random value is chosen
                independently for each frame that the module sends back to the client.
            
    
            
    
                While more padding bytes give better message length obfuscation, they
                are also additional traffic. The optimal number therefore depends on
                the kind of web traffic the server carries.
            
    
            
    
                The default of 0, e.g. no padding, was chosen for maximum backward
                compatibility. There might be deployments where padding bytes are
                unwanted or do harm. The most likely cause would be a client that
                has a faults implementation.

                This directive toggles the usage of the HTTP/2 server push 
                protocol feature.
            
    
            
    
                The HTTP/2 protocol allows the server to push other resources to
                a client when it asked for a particular one. This is helpful
                if those resources are connected in some way and the client can
                be expected to ask for it anyway. The pushing then saves the
                time it takes the client to ask for the resources itself. On the
                other hand, pushing resources the client never needs or already
                has is a waste of bandwidth.
            
    
            
    
                Server pushes are detected by inspecting the Link headers of
                responses (see https://tools.ietf.org/html/rfc5988 for the 
                specification). When a link thus specified has the rel=preload
                attribute, it is treated as a resource to be pushed.
            
    
            
     
                Link headers in responses are either set by the application or
                can be configured via H2PushResource or
                using mod_headers as:
            
    
            
    mod_headers example
    <Location /index.html>
    Header add Link "</css/site.css>;rel=preload"
    Header add Link "</images/logo.jpg>;rel=preload"
</Location>
    

    
            
    
                As the example shows, there can be several link headers added
                to a response, resulting in several pushes being triggered. There
                are no checks in the module to avoid pushing the same resource
                twice or more to one client. Use with care.
            
    
            
     
                HTTP/2 server pushes are enabled by default. On a server or virtual host,
                you may enable/disable this feature for any connection to the host. In addition,
                you may disable PUSH for a set of resources in a Directory/Location. This controls
                which resources may cause a PUSH, not which resources may be sent via PUSH.

                Last but not least, pushes happen only when the client signals
                its willingness to accept those. Most browsers do, some, like Safari 9,
                do not. Also, pushes also only happen for resources from the same
                authority as the original response is for.

                This directive toggles the maximum number of HTTP/2 server pushes 
                that are remembered per HTTP/2 connection. This can be used inside the
                <VirtualHost> 
                section to influence the number for all connections to that virtual host. 
            
    
            
    
                The push diary records a digest (currently using a 64 bit number) of pushed
                resources (their URL) to avoid duplicate pushes on the same connection.
                These value are not persisted, so clients opening a new connection
                will experience known pushes again. There is ongoing work to enable
                a client to disclose a digest of the resources it already has, so
                the diary maybe initialized by the client on each connection setup.
            
    
            
    
                If the maximum size is reached, newer entries replace the oldest
                ones. A diary entry uses 8 bytes, letting a
                default diary with 256 entries consume around 2 KB of memory.
            
    
            
    
                A size of 0 will effectively disable the push diary.

    H2PushPriority Directive

    Default:H2PushPriority * After 16
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_http2
    

    Compatibility:Available in version 2.4.18 and later. For having an
            effect, a nghttp2 library version 1.5.0 or newer is necessary.
    

    
            
    
                This directive defines the priority handling of pushed responses
                based on the content-type of the response. This is usually defined
                per server config, but may also appear in a virtual host. 
            
    
            
    
                HTTP/2 server pushes are always related to a client request. Each
                such request/response pairs, or streams have a dependency
                and a weight, together defining the priority of a stream. 
            
    
            
    
                When a stream depends on another, say X depends on Y,
                then Y gets all bandwidth before X gets any. Note that this
                does not mean that Y will block X. If Y has no data to send, 
                all bandwidth allocated to Y can be used by X.
            
    
            
    
                When a stream has more than one dependent, say X1 and X2 both
                depend on Y, the weight determines the bandwidth
                allocation. If X1 and X2 have the same weight, they both get
                half of the available bandwidth. If the weight of X1 is twice
                as large as that for X2, X1 gets twice the bandwidth of X2.
            
    
            
     
                Ultimately, every stream depends on the root stream which
                gets all the bandwidth available, but never sends anything. So all
                its bandwidth is distributed by weight among its children. Which
                either have data to send or distribute the bandwidth to their
                own children. And so on. If none of the children have data
                to send, that bandwidth get distributed somewhere else according
                to the same rules.
            
    
            
     
                The purpose of this priority system is to always make use of
                available bandwidth while allowing precedence and weight
                to be given to specific streams. Since, normally, all streams
                are initiated by the client, it is also the one that sets
                these priorities.
            
    
            
    
                Only when such a stream results in a PUSH, gets the server to
                decide what the initial priority of such a pushed
                stream is. In the examples below, X is the client stream. It
                depends on Y and the server decides to PUSH streams P1 and P2
                onto X.
            
    
            
    
                The default priority rule is:
            
    
            
    Default Priority Rule
    H2PushPriority * After 16
    

    
            
    
                which reads as 'Send a pushed stream of any content-type
                depending on the client stream with weight 16'. And so P1
                and P2 will be send after X and, as they have equal weight,
                share bandwidth equally among themselves.
            
    
            
    Interleaved Priority Rule
    H2PushPriority text/css Interleaved 256
    

    
            
    
                which reads as 'Send any CSS resource on the same dependency and
                weight as the client stream'. If P1 has content-type 'text/css',
                it will depend on Y (as does X) and its effective weight will be
                calculated as P1ew = Xw * (P1w / 256). With P1w being 
                256, this will make the effective weight the same as the weight
                of X. If both X and P1 have data to send, bandwidth will be allocated
                to both equally.
            
    
            
    
                With Pw specified as 512, a pushed, interleaved stream would
                get double the weight of X. With 128 only half as much. Note that
                effective weights are always capped at 256.
            
    
            
    Before Priority Rule
    H2PushPriority application/json Before
    

    
            
    
                This says that any pushed stream of content type 'application/json'
                should be send out before X. This makes P1 dependent
                on Y and X dependent on P1. So, X will be stalled as long as
                P1 has data to send. The effective weight is inherited from the
                client stream. Specifying a weight is not allowed.
            
    
            
    
                Be aware that the effect of priority specifications is limited
                by the available server resources. If a server does not have
                workers available for pushed streams, the data for the stream
                may only ever arrive when other streams have been finished.
            
    
            
    
                Last, but not least, there are some specifics of the syntax
                to be used in this directive:
            
    
            
      
                
    1. '*' is the only special content-type that matches all others. 
                    'image/*' will not work.
      2. 
                
    2. The default dependency is 'After'. 
      3. 
                
    3. There are also default weights: for 'After' it is 16, 'interleaved' is 256. 
                
      4. 
            
    
            
    Shorter Priority Rules
    H2PushPriority application/json 32         # an After rule
H2PushPriority image/jpeg before           # weight inherited
H2PushPriority text/css   interleaved      # weight 256 default

                When added to a directory/location HTTP/2 PUSHes will be attempted
                for all paths added via this directive. This directive can be used
                several times for the same location.
            
    
            
    
                This directive pushes resources much earlier than adding 
                Link headers via mod_headers.
                mod_http2 announces these resources in a
                103 Early Hints interim response to the client.
                That means that clients not supporting PUSH will still get
                early preload hints.
            
    
            
    
                In contrast to setting Link response headers 
                via mod_headers, this directive will only
                take effect on HTTP/2 connections. 
            
    
            
    
                By adding critical to such a resource, the server
                will give processing it more preference and send its data, once
                available, before the data from the main request.

                This directive sets the number of seconds of idle time on a TLS
                connection before the TLS write size falls back to small (~1300 bytes)
                length.
                This can be used server wide or for specific
                <VirtualHost>s. 
            
    
            
    
                See H2TLSWarmUpSize for a
                description of TLS warmup. H2TLSCoolDownSecs reflects the fact
                that connections may deteriorate over time (and TCP flow adjusts)
                for idle connections as well. It is beneficial to overall performance
                to fall back to the pre-warmup phase after a number of seconds that
                no data has been sent. 
            
    
            
    
                In deployments where connections can be considered reliable, this
                timer can be disabled by setting it to 0. 
            
    
            
    
                The following example sets the seconds to zero, effectively disabling
                any cool down. Warmed up TLS connections stay on maximum record
                size.

                This directive sets the number of bytes to be sent in small
                TLS records (~1300 bytes) until doing maximum sized writes (16k)
                on https: HTTP/2 connections.
                This can be used server wide or for specific
                <VirtualHost>s. 
            
    
            
    
                Measurements by google performance
                    labs show that best performance on TLS connections is reached,
                if initial record sizes stay below the MTU level, to allow a
                complete record to fit into an IP packet.
            
    
            
    
                While TCP adjust its flow-control and window sizes, longer TLS
                records can get stuck in queues or get lost and need retransmission.
                This is of course true for all packets. TLS however needs the 
                whole record in order to decrypt it. Any missing bytes at the end
                will stall usage of the received ones.
            
    
            
    
                After a sufficient number of bytes have been send successfully,
                the TCP state of the connection is stable and maximum TLS record
                sizes (16 KB) can be used for optimal performance.
            
    
            
    
                In deployments where servers are reached locally or over reliable
                connections only, the value might be decreased with 0 disabling
                any warmup phase altogether.
            
    
            
    
                The following example sets the size to zero, effectively disabling
                any warmup phase.

                This method of switching protocols is defined in HTTP/1.1 and
                uses the "Upgrade" header (thus the name) to announce willingness
                to use another protocol. This may happen on any request of a
                HTTP/1.1 connection.
            
    
            
    
                This method of protocol switching is enabled by default on cleartext

                Please be aware that Upgrades are only accepted for requests

                This directive sets the size of the window that is used for flow control
                from client to server and limits the amount of data the server has to buffer.
                The client will stop sending on a stream once the limit has been reached until
                the server announces more available space (as it has processed some of the data).
            
    
                This limit affects only request bodies, not its meta data such as headers. Also,
                it has no effect on response bodies as the window size for those are managed
                by the clients.
            
    
            
    Example
    H2WindowSize 128000

    Description:Send static content at a bandwidth rate limit, defined by the various old modem standards
    

    Status:Experimental
    

    Module Identifier:dialup_module
    

    Source File:mod_dialup.c
    

    Summary
    


    It is a module that sends static content at a bandwidth rate limit, defined
by the various old modem standards. So, you can browse your site with a 56k
V.92 modem, by adding something like this:
    


    <Location "/mysite">
    ModemStandard "V.92"
</Location>
    



    Previously to do bandwidth rate limiting modules would have to block an entire
thread, for each client, and insert sleeps to slow the bandwidth down.
Using the new suspend feature, a handler can get callback N milliseconds in
the future, and it will be invoked by the Event MPM on a different thread,
once the timer hits.  From there the handler can continue to send data to the client.

    Description:Logging of input and output bytes per request
    

    Status:Extension
    

    Module Identifier:logio_module
    

    Source File:mod_logio.c
    

    Summary
    


    
    This module provides the logging of input and output number of
    bytes received/sent per request. The numbers reflect the actual bytes
    as received on the network, which then takes into account the
    headers and bodies of requests and responses. The counting is done
    before SSL/TLS on input and after SSL/TLS on output, so the numbers
    will correctly reflect any changes made by encryption.
    

    
    This module requires mod_log_config.
    

    
    When KeepAlive connections are used with SSL, the overhead of the SSL
    handshake is reflected in the byte count of the first request on the
    connection.  When per-directory SSL renegotiation occurs, the bytes are associated
    with the request that triggered the renegotiation.

    Custom Log Formats
    


    
    This module adds three new logging directives. The characteristics of the
    request itself are logged by placing "%" directives in
    the format string, which are replaced in the log file by the values as
    follows:
    

    
    Format String
        Description
    

    %I
        Bytes received, including request and headers, cannot be
        zero.
    

    %O
        Bytes sent, including headers, cannot be zero.
    

    %S
        Bytes transferred (received and sent), including request and headers,
        cannot be zero. This is the combination of %I and %O.
    
        Available in Apache 2.4.7 and later
    

    %^FB
        Delay in microseconds between when the request arrived and the
        first byte of the response headers are written.  Only available if 
        LogIOTrackTTFB is set to ON.
    
        Available in Apache 2.4.13 and later
    

    

    
    Usually, the functionality is used like this:
    

    
    
      
    Combined I/O log format:
    
      
    "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
      \"%{User-agent}i\" %I %O"

    LogIOTrackTTFB Directive
    

    

    Description:Enable tracking of time to first byte (TTFB)
    

    Syntax:LogIOTrackTTFB ON|OFF
    

    Default:LogIOTrackTTFB OFF
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:All
    

    Status:Extension
    

    Module:mod_logio
    

    Compatibility:Apache HTTP Server 2.4.13 and later
    

    
    
    This directive configures whether this module tracks the delay
    between the request being read and the first byte of the response
    headers being written.  The resulting value may be logged with the 
    %^FB format.

    Description:Forensic Logging of the requests made to the server
    

    Status:Extension
    

    Module Identifier:log_forensic_module
    

    Source File:mod_log_forensic.c
    

    Compatibility:mod_unique_id is no longer required since
version 2.1
    

    Summary
    

    
    This module provides for forensic logging of client
    requests. Logging is done before and after processing a request, so the
    forensic log contains two log lines for each request.
    The forensic logger is very strict, which means:
    

    
      
    
    • The format is fixed. You cannot modify the logging format at
    runtime.
      • 
    
    • If it cannot write its data, the child process
    exits immediately and may dump core (depending on your
    CoreDumpDirectory
    configuration).
      • 
    
    

    
    The check_forensic script, which can be found in the
    distribution's support directory, may be helpful in evaluating the
    forensic log output.
    

    


    top
    

    

    Forensic Log Format
    
    
    Each request is logged two times. The first time is before it's
    processed further (that is, after receiving the headers). The second log
    entry is written after the request processing at the same time
    where normal logging occurs.
    

    
    In order to identify each request, a unique request ID is assigned.
    This forensic ID can be cross logged in the normal transfer log using the
    %{forensic-id}n format string. If you're using
    mod_unique_id, its generated ID will be used.
    

    
    The first line logs the forensic ID, the request line and all received
    headers, separated by pipe characters (|). A sample line
    looks like the following (all on one line):
    

    
    
        +yQtJf8CoAB4AAFNXBIEAAAAA|GET /manual/de/images/down.gif
        HTTP/1.1|Host:localhost%3a8080|User-Agent:Mozilla/5.0 (X11;
        U; Linux i686; en-US; rv%3a1.6) Gecko/20040216
        Firefox/0.8|Accept:image/png, etc...
    
    

    
    The plus character at the beginning indicates that this is the first log
    line of this request. The second line just contains a minus character and
    the ID again:
    

    
    
      -yQtJf8CoAB4AAFNXBIEAAAAA
    
    

    
    The check_forensic script takes as its argument the name
    of the logfile. It looks for those +/- ID pairs
    and complains if a request was not completed.
    

    top
    

    

    Security Considerations
    
    
    See the security tips
    document for details on why your security could be compromised
    if the directory where logfiles are stored is writable by
    anyone other than the user that starts the server.
    
    
    The log files may contain sensitive data such as the contents of 
    Authorization: headers (which can contain passwords), so
    they should not be readable by anyone except the user that starts the
    server.
    

    

    top
    

    ForensicLog Directive
    

    

    Description:Sets filename of the forensic log
    

    Syntax:ForensicLog filename|pipe
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_log_forensic
    

    
    
    The ForensicLog directive is used to
    log requests to the server for forensic analysis. Each log entry
    is assigned a unique ID which can be associated with the request
    using the normal CustomLog
    directive. mod_log_forensic creates a token called
    forensic-id, which can be added to the transfer log
    using the %{forensic-id}n format string.
    

    
    The argument, which specifies the location to which
    the logs will be written, can take one of the following two
    types of values:
    

    
    
      
    filename
    
      
    A filename, relative to the ServerRoot.
    

      
    pipe
    
      
    The pipe character "|", followed by the path
      to a program to receive the log information on its standard
      input. The program name can be specified relative to the ServerRoot directive.

      
    Security:
    
      
    If a program is used, then it will be run as the user who
      started httpd. This will be root if the server was
      started by root; be sure that the program is secure or switches to a
      less privileged user.
    
      
    

      
    Note
    
        
    When entering a file path on non-Unix platforms, care should be taken
        to make sure that only forward slashes are used even though the platform
        may allow the use of back slashes. In general it is a good idea to always
        use forward slashes throughout the configuration files.

    Apache Module mod_remoteip
    

    

    Available Languages:  en  |

    Description:Replaces the original client IP address for the connection
with the useragent IP address list presented by a proxies or a load balancer
via the request headers.

    

    Status:Base
    

    Module Identifier:remoteip_module
    

    Source File:mod_remoteip.c
    

    Summary
    

    
    This module is used to treat the useragent which initiated the
    request as the originating useragent as identified by httpd for the
    purposes of authorization and logging, even where that useragent is
    behind a load balancer, front end server, or proxy server.
    

    
    The module overrides the client IP address for the connection
    with the useragent IP address reported in the request header configured
    with the RemoteIPHeader directive.
    

    
    Additionally, this module implements the server side of
    HAProxy's
    PROXY Protocol when
    using the RemoteIPProxyProtocol
    directive.
    

    
    Once replaced as instructed, this overridden useragent IP address is
    then used for the mod_authz_host
    Require ip
    feature, is reported by mod_status, and is recorded by
    mod_log_config %a and core
    %a format strings. The underlying client IP of the connection
    is available in the %{c}a format string.
    

    
    It is critical to only enable this behavior from
    intermediate hosts (proxies, etc) which are trusted by this server, since
    it is trivial for the remote useragent to impersonate another
    useragent.
    

    


    top
    

    

    Remote IP Processing
    

    
    Apache by default identifies the useragent with the connection's
    client_ip value, and the connection remote_host and remote_logname are
    derived from this value. These fields play a role in authentication,
    authorization and logging and other purposes by other loadable
    modules.
    

    
    mod_remoteip overrides the client IP of the connection with the
    advertised useragent IP as provided by a proxy or load balancer, for
    the duration of the request. A load balancer might establish a long
    lived keepalive connection with the server, and each request will
    have the correct useragent IP, even though the underlying client IP
    address of the load balancer remains unchanged.
    

    
    When multiple, comma delimited useragent IP addresses are listed in the
    header value, they are processed in Right-to-Left order.  Processing
    halts when a given useragent IP address is not trusted to present the
    preceding IP address.  The header field is updated to this remaining
    list of unconfirmed IP addresses, or if all IP addresses were trusted,
    this header is removed from the request altogether.
    

    
    In overriding the client IP, the module stores the list of intermediate
    hosts in a remoteip-proxy-ip-list note, which mod_log_config
    can record using the %{remoteip-proxy-ip-list}n format token.
    If the administrator needs to store this as an additional header, this
    same value can also be recording as a header using the directive
    RemoteIPProxiesHeader.
    

    
    IPv4-over-IPv6 Mapped Addresses
    
    As with httpd in general, any IPv4-over-IPv6 mapped addresses are recorded
    in their IPv4 representation.
    

    
    Internal (Private) Addresses
    
    All internal addresses 10/8, 172.16/12, 192.168/16, 169.254/16 and 127/8
    blocks (and IPv6 addresses outside of the public 2000::/3 block) are only
    evaluated by mod_remoteip when RemoteIPInternalProxy
    internal (intranet) proxies are registered.

    RemoteIPHeader Directive
    

    

    Description:Declare the header field which should be parsed for useragent IP addresses
    

    Syntax:RemoteIPHeader header-field
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_remoteip
    

    
    
    The RemoteIPHeader directive triggers
    mod_remoteip to treat the value of the specified
    header-field header as the useragent IP address, or list
    of intermediate useragent IP addresses, subject to further configuration
    of the RemoteIPInternalProxy and
    RemoteIPTrustedProxy directives.  Unless these
    other directives are used, mod_remoteip will trust all
    hosts presenting a RemoteIPHeader IP value.

    Status:Base
    

    Module:mod_remoteip
    

    
    
    The RemoteIPInternalProxy directive adds one
    or more addresses (or address blocks) to trust as presenting a valid
    RemoteIPHeader value of the useragent IP.  Unlike the
    RemoteIPTrustedProxy directive, any IP address
    presented in this header, including private intranet addresses, are
    trusted when passed from these proxies.
    

    
    Internal (Load Balancer) Example

    Status:Base
    

    Module:mod_remoteip
    

    
    
    The RemoteIPInternalProxyList directive specifies
    a file parsed at startup, and builds a list of addresses (or address blocks)
    to trust as presenting a valid RemoteIPHeader value of the useragent IP.
    

    
    The '#' hash character designates a comment line, otherwise
    each whitespace or newline separated entry is processed identically to
    the RemoteIPInternalProxy directive.

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_remoteip
    

    
    
    The RemoteIPProxiesHeader directive specifies
    a header into which mod_remoteip will collect a list of
    all of the intermediate client IP addresses trusted to resolve the useragent
    IP of the request. Note that intermediate
    RemoteIPTrustedProxy addresses are recorded in
    this header, while any intermediate
    RemoteIPInternalProxy addresses are discarded.

    RemoteIPProxyProtocol Directive
    

    

    Description:Enable or disable PROXY protocol handling
    

    Syntax:RemoteIPProxyProtocol On|Off
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_remoteip
    

    Compatibility:RemoteIPProxyProtocol is only available in httpd 2.4.31 and newer
    

    
    
    The RemoteIPProxyProtocol directive enables or 
    disables the reading and handling of the PROXY protocol connection header.
    If enabled with the On flag, the upstream client must
    send the header every time it opens a connection or the connection will
    be aborted unless it is in the list of disabled hosts provided by the
    RemoteIPProxyProtocolExceptions
    directive.
    

    
    While this directive may be specified in any virtual host, it is
    important to understand that because the PROXY protocol is connection
    based and protocol agnostic, the enabling and disabling is actually based
    on IP address and port. This means that if you have multiple name-based
    virtual hosts for the same host and port, and you enable it for any one of
    them, then it is enabled for all of them (with that host and port). It also
    means that if you attempt to enable the PROXY protocol in one and disable
    in the other, that won't work; in such a case, the last one wins and a
    notice will be logged indicating which setting was being overridden.

    Compatibility:RemoteIPProxyProtocolExceptions is only available in httpd 2.4.31 and newer
    

    
    
    The RemoteIPProxyProtocol directive enables or
    disables the reading and handling of the PROXY protocol connection header.
    Sometimes it is desirable to require clients to provide the PROXY header, but
    permit other clients to connect without it. This directive allows a server 
    administrator to configure a single host or CIDR range of hosts that may do
    so. This is generally useful for monitoring and administrative traffic to a 
    virtual host direct to the server behind the upstream load balancer.

    RemoteIPTrustedProxy Directive

    Module:mod_remoteip
    

    
    
    The RemoteIPTrustedProxy directive adds one
    or more addresses (or address blocks) to trust as presenting a valid
    RemoteIPHeader value of the useragent IP.  Unlike the
    RemoteIPInternalProxy directive, any intranet
    or private IP address reported by such proxies, including the 10/8, 172.16/12,
    192.168/16, 169.254/16 and 127/8 blocks (or outside of the IPv6 public
    2000::/3 block) are not trusted as the useragent IP, and are left in the
    RemoteIPHeader header's value.

    Özet
    


    
    Bu modül her istekte alınan ve gönderilen bayt sayısının günlüklenmesini
      sağlar. Sayılar, istekte ve yanıtta yer alan başlıklar ve gövdeleri
      hesaba dahil ederek ağ üzerinde gerçekte gidip gelen bayt sayısını
      gösterir. Bayt sayımı, girdide SSL/TLS öncesinde ve çıktıda SSL/TLS
      sonrasında yapılır, böylece sayıların, şifrelemeyle herhangi bir
      değişikliği doğru olarak yansıtması sağlanmış olur.
    

    
    Bu modül mod_log_config modülünü gerektirir.
    

    
    SSL ile KeepAlive bağlantılar kullanıldığında, SSL
      uzlaşımının ek yükü, bağlantı üzerinden yapılan ilk isteğin bayt sayısını
      yansıtır. Her dizin için yeniden uzlaşım gerektiği takdirde bayt sayısı
      yeniden uzlaşımı tetikleyen istekle ilişkilendirilir.

    Apache
    

    Sommaire
    

        
    
	Ce module permet de gérer les propriétés courantes des domaines pour un
	ou plusieurs serveurs virtuels. Il fournit deux fonctionnalités
	principales : la première permet la supervision et le renouvellement des
	certificats https: via le protocole ACME (RFC 8555). Le module
	effectue le renouvellement des certificats avant leur expiration
	afin d'éviter une interruption des services internet. Il est possible de
	monitorer l'état de tous les certificats gérés par mod_md et de configurer
	le serveur de façon à ce qu'il envoie des notifications de
	renouvellement, d'expiration ou d'erreur personnalisées.
	
    
	La seconde fonctionnalité principale fournit une implémentation
	alternative de l'agrafage OCSP, et ceci aussi bien pour les certificats
	gérés par mod_md que pour les certificats que vous gérez vous-même.
	Composant nécessaire pour tout site https, l'agrafage OCSP influence la
	vitesse de chargement des pages et suivant la configuration, la
	disponibilité de ces dernières. Vous trouverez plus de détails dans la section
	agrafage ci-dessous.
        
    
        L'autorité ACME par défaut pour la gestion des certificats est Let's Encrypt, mais il est possible
	de configurer une autre CA si cette dernière supporte le protocole.
        
    
        
        
    Exemple de configuration simple :
    
        
        
    TLS dans un contexte de serveur virtuel
    
        
    MDomain example.org

<VirtualHost *:443>
    ServerName example.org
    DocumentRoot htdocs/a

    SSLEngine on
    # aucun certificat spécifié
</VirtualHost>
    

        
    
            Au démarrage, un serveur ainsi configuré contactera Let's Encrypt pour demander un
	    certificat pour le domaine considéré. Si Let's Encrypt peut vérifier
	    le propriétaire du domaine, le module obtiendra le certificat et sa
	    chaîne de certification, le stockera dans son système de fichiers
	    (voir la directive MDStoreDir) et le proposera au prochain
	    redémarrage à mod_ssl.
        
    
            Ce processus se déroule pendant l'exécution du serveur. Tous les
	    autres serveurs virtuels continueront à fonctionner normalement,
	    mais tant que le certificat ne sera pas disponible, toute requête
	    pour le domaine considéré génèrera une réponse du type '503 Service
	    Unavailable'. 
        
    
        
    

        
    Prérequis
    
        
    
            Pour pouvoir être utilisé, ce module nécessite le chargement
	    préalable du module mod_watchdog.
        
    
            Pour que Let's Encrypt puisse signer et renouveler votre certificat,
	    votre serveur doit être accessible depuis l'internet public sur le port 80
	    (http:) et/ou 443 (https:), à moins que votre serveur soit configuré
	    pour utiliser les vérifications DNS - pour plus de détails, voir
	    "certificats génériques".
        
    
            Le module choisit une des méthodes proposées par Let's Encrypt. En
	    général, LE propose des méthodes de vérification sur les ports ou le
	    DNS et Apache choisit une des méthodes disponibles.    
        
    
            Pour déterminer quelles méthodes sont disponibles, le module
	    consulte les ports sur lesquels écoute Apache httpd. Si le port 80 en
	    fait partie, le module supposera que la vérification http: nommée
	    http-01 est disponible. Si le port 443 en fait aussi partie, la
	    vérification https: nommée tls-alpn-01 sera ajoutée à la liste des
	    méthodes disponibles. Enfin, si la directive MDChallengeDns01 est définie, la méthode
	    de vérification dns-01 sera aussi ajoutée. 
        
    
            Si votre configuration est plus complexe, deux méthodes permettent
	    d'orienter ce choix. En premier lieu, voyez du côté de la directive
	    MDPortMap si le serveur se
	    trouve derrière un redirecteur de port comme un pare-feu. En second
	    lieu, vous pouvez court-circuiter entièrement le processus de choix
	    du module en définissant directement la directive MDCAChallenges.  
        
    
        
    

        
    Vérifications https:
    
        
    
            Pour la vérification de domaine via le protocole TLS, le nom de la
	    méthode correspondante est "tls-alpn-01". Le serveur Apache doit
	    alors être en écoute sur le port 443 (voir la directive MDPortMap si vous redirigez ce port vers
	    un autre).
        
    
            Let's Encrypt ouvrira alors une connexion TLS avec Apache en
	    utilisant l'indicateur spécial "acme-tls/1" (cette portion
	    indication de TLS se nomme ALPN, d'où le nom de la méthode de
	    vérification. ALPN est aussi utilisé par les navigateurs pour ouvrir
	    une connexion HTTP/2.
        
    
            Si vous ne souhaitez cependant qu'aucun de vos sites ne soit
	    accessible sur le port 80, vous pouvez laiser ce dernier ouvert et
	    rediriger toutes les requêtes vers vos sites en https:. Pour
	    ce faire, utilisez la directive MDRequireHttps décrite plus loin. Votre
	    serveur pourra alors continuer à répondre au requêtes en http: en
	    provenance de Let's Encrypt.
	    Comme dans le cas du protocole HTTP/2, vous pouvez configurer ceci
	    de la manière suivante :
        
    
	
    Protocols h2 http/1.1 acme-tls/1
    

        
    
            La méthode de vérification "tls-alpn-01" sera alors disponible.
	
    
        
    
	
    Certificats génériques
    
        
    
            Les certificats génériques sont supportés à partir de la version 2.x
	    de mod_md, mais leur obtention n'est pas triviale. Let's Encrypt
	    impose pour ces derniers la vérification "dns-01".
	    Aucune autre n'est considérée comme suffisamment efficace.
        
    
	    Apache ne peut cependant pas implémenter cette vérification de
	    lui-même . Comme son nom l'indique, "dns-01" vous demande de
	    présenter certains enregistrement DNS spécifiques à votre domaine
	    qui doivent contenir certaines données de vérification. Vous devez
	    donc être en mesure d'éditer et modifier les enregistrements DNS de
	    votre domaine.
        
    
            Si c'est le cas, vous pouvez procéder via mod_md. Supposons que vous
	    disposiez pour cela du script /usr/bin/acme-setup-dns ; vous
	    configurez alors Apache comme suit :
        
    
        
    MDChallengeDns01 /usr/bin/acme-setup-dns
    

        
    
            Apache fera alors appel à ce script lorsqu'il aura besoin de
	    définir ou détruire un enregistrement DNS de vérification pour le
	    domaine considéré.
        
    
            Supposons ainsi que vous souhaitiez obtenir un certificat pour
	    *.mydomain.com ;  mod_md va appeler :
        
    
        
    /usr/bin/acme-setup-dns setup mydomain.com challenge-data
# ceci nécessite de supprimer tout enregistrement DNS TXT pour
# _acme-challenge.mydomain.com et d'en créer un nouveau dont le contenu sera
# "challenge-data"
    

        
    
            il appellera ensuite :
        
    
        
    /usr/bin/acme-setup-dns teardown mydomain.com
# ceci nécessite de supprimer tout enregistrement DNS TXT pour
# _acme-challenge.mydomain.com
    

        
    

        
    Monitoring
    
            
    Apache possède un module de monitoring standard :
	    mod_status. mod_md y ajoute une section et facilite
	    le monitoring de votre domaine.
            
    
                Vous pouvez alors visualiser tous vos domaines gérés par ordre
		alphabétique, les noms de domaine qu'ils contiennent, un état
		global, les date d'expiration ainsi que des paramètres
		spécifiques. Ces derniers comprennent la périodicité de
		renouvellement que vous avez sélectionnée (ou la valeur par
		défaut), la CA (autorité de certification) utilisée, etc...
            
    
                La colonne "Renewal" montre des rapports d'activité ou d'erreur
		à propos des renouvellements de certificats, ce qui devrait
		faciliter la vie des utilisateurs qui souhaitent savoir si tout
		fonctionne correctement ou si des problèmes se produisent.
            
    
                Si un des domaines gérés provoque une erreur, elle apparaîtra
		aussi ici, ce qui vous permettra de visualiser les éventuels
		problèmes sans devoir vous plonger dans les journaux du serveur.
            
    
                Il existe aussi un nouveau gestionnaire, "md-status", qui peut
		vous fournir les informations à propos des domaines gérés à
		partir de "server-status" et au format JSON. Vous pouvez le
		configurer comme suit sur votre serveur :
            
    
            
    <Location "/md-status">
  SetHandler md-status
</Location>
    

            
    
                Comme pour "server-status", vous devez
		ajouter les autorisations nécessaires. 
            
    
                Si vous ne souhaitez recevoir l'état JSON que pour un domaine
		spécifique, ajoutez le simplement à votre URL d'état :
            
    
            
    > curl https://<yourhost>/md-status/another-domain.org
{
  "name": "another-domain.org",
  "domains": [
    "another-domain.org",
    "www.another-domain.org"
  ],
  ...
    

            
    
                Cet état JSON montre aussi un journal des renouvellements de
		certificats :
            
    
            
    {
"when": "Wed, 19 Jun 2019 14:45:58 GMT",
"type": "progress", "detail": "The certificate for the managed domain has been renewed successfully and can be used. A graceful server restart now is recommended."
},{
"when": "Wed, 19 Jun 2019 14:45:58 GMT",
"type": "progress", "detail": "Retrieving certificate chain for test-901-003-1560955549.org"
},{
"when": "Wed, 19 Jun 2019 14:45:58 GMT",
"type": "progress", "detail": "Waiting for finalized order to become valid"
},{
"when": "Wed, 19 Jun 2019 14:45:50 GMT",
"type": "progress", "detail": "Submitting CSR to CA for test-901-003-1560955549.org"
},
...
    

            
    
                Vous trouverez aussi ces informations dans le fichier "job.json"
		dans votre répertoire de test et, s'il est activé, dans le
		répertoire des domaines. Vous pourrez ainsi les consulter à tout
		moment. 
            
    
                Enfin, la directive MDCertificateStatus donne accès au
		informations à propos du certificat spécifié au format JSON.
            
    
        
    

	
    Agrafage
    
            
    
                Si vous voulez commencer par tester l'agrafage pour un seul
		domaine géré, utilisez cette configuration :
            
    
            
    <MDomain mydomain.net>
  MDStapling on
</MDomain>
    

            
    
		et utilisez 'server-status' et/ou MDMessageCmd pour voir comment tout
		cela fonctionne. Vous pourrez alors vérifier si l'information
		d'agrafage est présente, sa durée de validité, son origine et à
		quel moment elle sera rafraîchie.
            
    
                Si tout fonctionne comme vous le souhaitez, vous pouvez définir
		cette configuration pour tous les certificats ou seulement vos
		certificats gérés.
            
    
                De nombreux sites utilisent l'implémentation d'agrafage
		existante de mod_ssl depuis des années. Les implémentations par
		mod-ssl et mod_md présentent deux différences principales :
            
    
            
      
                
    1. Lecture des informations à la demande ou de manière planifiée
		: mod_ssl extrait les informations d'agrafage lorsque le besoin
		s'en fait sentir, par exemple lors d'une nouvelle connexion. mod_md
		quant à lui, extrait ces informations au démarrage du serveur et
		lorsqu'elles ont atteint les deux tiers de leur durée de vie.
      2. 
                
    2. Conservation des informations en mémoire ou de manière
		persistante : mod_ssl peut conserver ces informations
		de manière persistante, mais la plupart des configurations
		exemples utilisent un cache en mémoire. mod_md quant à lui,
		stocke systématiquement les informations dans le système de
		fichiers.
      3. 
            
    
            
    
                Si par malchance vous redémarrez votre serveur alors que le
		service OCSP de votre CA est en panne, les utilisateurs ne
		pourront plus atteindre vos sites. Sans persistance des
		informations, votre serveur n'est plus en mesure de fournir au
		client les données nécessaires, et le navigateur client ne peut
		pas les obtenir lui-même car le service OCSP ne répond pas. 
            
    
                Avec l'implémentation de mod_md, l'information d'agrafage est
		stockée de manière persistante, et elle peut donc être réchargée
		au démarrage du serveur et être ainsi disponible pour les
		connexions entrantes. Un jour ou deux avant expiration des
		informations, mod_md va les renouveler, ce qui permet de faire
		face à un temps d'indisponibilité du service OCSP assez long.
            
    
                Pour conserver une compatibilité ascendante, l'implémentation de
		mod_ssl n'a pas pu être modifiée en profondeur. Par exemple,
		mod_ssl est incapable d'ajouter une dépendance à mod_watchdog
		sans rendre inutilisables de nombreuses configurations
		existantes qui ne chargent pas ce module.

		Cette directive permet de définir les types de négociation
		utilisés (par ordre de préférences) pour prouver l'appartenance
		du domaine. Les types de négociation supportés par le module
		sont 'tls-alpn-01', 'dns-01' et 'http-01'. Le module parcourt
		toute la configuration du serveur pour déterminer quelles
		méthodes peuvent être utilisées.
            
    
		Si par exemple le serveur est en écoute sur le port 80, c'est la
		méthode 'http-01' qui sera disponible. Pour 'dns-01', une
		commande MDChallengeDns01
		définie sera requise. La méthode 'tls-alpn-01' est décrite
		ci-dessus dans 'https: Challenges'.
            
    
                Cette sélection automatique fonctionne pour la plupart des
		configurations. Mais comme Apache est un serveur très puissant
		avec de nombreuses options de configuration, certains cas
		pourront poser des problèmes. Par exemple, il peut être en
		écoute sur plusieurs adresses IP, certaines étant accessibles en
		https: et d'autres non.
            
    
		Si vous définissez MDCAChallenges
		directement, la sélection automatique est désactivée. A la
		place, le module va utiliser la liste de méthodes de négociation
		spécifiée pour dialoguer avec le serveur ACME (un type de
		négociation doit aussi être proposé par le serveur). Ces
		méthodes de négociation sont examinées dans l'ordre selon lequel
		elles sont spécifiées.

                Chaque version possède deux modes de fonctionnement : un mode
		production et un mode test. Le mode test est identique au mode
		production, à la différence près que le certificat ne sera pas
		reconnu par les navigateurs. Il est aussi beaucoup plus souple
		quant aux limitations en performances. Il permet de tester de

                Cette directive s'utilise dans une section MDomainSet et permet de spécifier le
		nom du fichier qui contiendra le certificat pour le
		domaine géré. La clé correspondante est spécifiée via la
		directive MDCertificateKeyFile.
            
    
            
    Exemple
    <MDomain mydomain.com>
  MDCertificateFile /etc/ssl/my.cert
  MDCertificateKeyFile /etc/ssl/my.key
</MDomain>
    

    

            
    
                Cette directive est équivalente à la directive SSLCertificateFile de mod_ssl. Elle
		s'utilise dans de nombreuses applications. 
            
    
                Une première application est la migration de la gestion des
		certificats d'un domaine existant depuis le mode statique via des
		fichiers vers le mode automatique via Let's Encrypt. A cet
		effet, vous définissez tout d'abord la section MDomainSet dans laquelle vous
		spécifiez les fichiers, puis supprimez la directive SSLCertificateFile de la
		configuration de vos serveurs virtuels. 
            
    
		Avec cette configuration, votre serveur fonctionnera comme
		avant, avec probablement moins de lignes répétitives. Vous
		pouvez alors ajouter la directive MDRenewMode avec pour valeur
		"always", et le module obtiendra un nouveau cerificat avant que
		celui du fichier considéré n'arrive à expiration. Une fois le
		certificat renouvelé, vous pouvez supprimer la directive
		MDCertificateFile et
		recharger la configuration.
            
    
                Une autre application est le renouvellement de vos certificats
		Let's Encrypt avec d'autres clients ACME comme l'excellent certbot. A cet effet, faites
		pointer vos domaines gérés vers les fichiers de certbot et ils
		travaillerons alors ensemble.

		pour accéder facilement à un moniteur de certificat. L'empreinte
		SHA256 du certificat doit être ajoutée à l'URL spécifié.
            
    
                Les moniteurs de certificat donnent accès aux enregistrements de
		la Certificate Transparency (CT) afin de tracer l'utilisation
		des certificats pour les domaines. Vous pourrez au moins
		vérifier si Let's Encrypt (ou tout autre CA que vous aurez
		défini) a bien inscrit votre certificat dans les enregistrements
		de CT.
            
    
                Avertissement : La mise à jour des enregistrements des
		certificats et leur prise en compte par les moniteurs peut
		prendre un certain temps. Ce dernier varie en fonction des
		enregistreurs et des moniteurs. Un nouveau certificat ne sera
		donc pas connu immédiatement.

		Certains CAs ACME ont besoin de ces valeurs, mais ce n'est pas
		le cas pour Let's Encrypt. Vérifiez avec votre CA ACME si vous
		avez besoin de ces valeurs et la manière de les obtenir. Ces
		dernières se composent de deux chaînes : un identifiant de clé

		Vous pouvez définir ces valeurs de manière globale ou pour un

		Le programme ne doit pas être bloquant car le module attend
		qu'il se termine. Un code de retour autre que 0 doit indiquer
		une erreur d'exécution. 
            
    
                "errored" n'est pas l'évènement à surveiller en priorité car le
		renouvellement du certificat est censé se produire suffisammant
		tôt pour éviter toute interruption de service. Cet évènement est
		signalé au plus une fois par heure.
            
    
                L'évènement "expiring", quant à lui, doit être pris au sérieux.
		Il se produit lorsque la valeur de MDWarnWindow est atteinte. Par
		défaut, cette valeur correspond à 10% de la durée de vie du
		certificat, donc actuellement pour Let's Encrypt, 9 jours avant
		expiration du certificat. Le message d'avertissement est répété
		au plus une fois par jour.
            
    
                'renewed' indique qu'un nouveau certificat a été obtenu et
		se trouve dans la zone intermédiaire du magasin MD. Il sera
		activé au prochain restart/reload du serveur.
            
    
		'installed' indique qu'un nouveau certificat a été transféré
		depuis la zone intermédiaire vers la zone des domaines du
		magasin MD. Cet évènement se produit lors d'un restart/reload du
		serveur. A la différence des autres commandes,
		MDMessageCmd s'exécute avec les
		permissions de root (sur les systèmes *nix) et a donc accès aux
		fichiers de certificats (et aux clés). Les certificats
		nécessaires à d'autres applications ou possédant des formats
		différents peuvent être traités suite à cet évènement.
            
    
                Un évènement de type 'renewing' est déclenché avant le démarrage
		du processus de renouvellement pour le domaine géré. Si dans ce
		cas la commande renvoie une valeur non nulle, le renouvellement
		sera interrompu et tenté à nouveau au cycle suivant. Certaines
		configurations de clusters l'utilisent pour n'effectuer le
		renouvellement que sur un seul noeud.
            
    
                Un évènement de type 'challenge-setup:type:domain' est déclenché
		lorsque les données de vérification pour un domaine ont été
		créées. Il est invoqué avant qu'il soit demandé au serveur ACME
		de les vérifier. type contient une des méthodes de vérification
		ACME. Il est invoqué pour chaque nom DNS d'un MDomain. Les
		configurations de clusters peuvent utiliser cet évènement pour
		distribuer les fichiers de vérification à tous les noeuds.
            
    
                Un évènement de type ocsp-errored est déclenché lorsque le
		MDStapling est activé pour un domaine, et indique qu'une erreur
		s'est produite en essayant d'obtenir la réponse OCSP  de
		l'autorité de certification. mod_md essaiera à nouveau d'obtenir
		cette réponse.

                Tous les domaines de la liste seront gérés par
		mod_md comme un seul domaine géré (Managed Domain - MD).
		mod_md ne demandera qu'un seul certificat qui
		sera valide pour tous ces noms de domaine. Cette directive
		s'utilise au niveau de la configuration globale (voir plus loin
		les autres directives MD). Si un domaine nécessite une
		configuration particulière, utilisez la directive <MDomainSet>.
            
    
		Deux définitions supplémentaires sont nécessaires pour un
		domaine géré : une adresse Email de contact (via MDContactEmail ou ServerAdmin) et MDCertificateAgreement.  L'adresse
		électronique du ServerAdmin
		permet de s'enregistrer auprès de l'autorité de certification
		(par défaut Let's Encrypt). L'autorité de certification
		l'utilisera pour vous informer à propos du statut de vos
		certificats ou d'éventuelles modifications de ses services.
            
    
                La seconde définition, MDCertificateAgreement doit avoir
		pour valeur "accepted". Vous confirmez ainsi que vous acceptez
		les conditions d'utilisation du CA.
            
    
            
    Exemple
    MDContactEmail admin@example.org
MDCertificateAgreement accepted
MDomain example.org www.example.org

                En plus de la liste des domaines gérés, cette directive accepte
		un paramètre supplémentaire qui peut prendre pour valeur
		'manual' ou 'auto'. Ce paramètre permet de définir si un domaine
		sera géré sous le nom spécifié dans la liste seul ('manual'),
		ou si tous les noms du serveur virtuel correspondant seront
		gérés ('auto'). C'est d'ailleurs cette dernière valeur qui
		est la valeur par défaut.
            
    
            
    Exemple
    MDomain example.org

<VirtualHost *:443>
    ServerName example.org
    ServerAlias www.example.org
    DocumentRoot htdocs/root

    SSLEngine on
</VirtualHost>

MDomain example2.org auto

<VirtualHost *:443>
    ServerName example2.org
    ServerAlias www.example2.org
    ...
</VirtualHost>
    

    
	    
     Dans cet exemple, le domaine 'www.example.org' est
	    automatiquement ajouté à la liste MD 'example.org'. De manière
	    similaire, le domaine 'www.example2.org' sera automatiquement ajouté
	    à la liste MD 'example2.org' pour laquelle 'auto' est explicitement
	    spécifié.  Chaque fois que vous ajouterez des noms à ces serveurs
	    virtuels via ServerAlias, ils seront ajoutés à la liste MD
	    correspondante.
            
    
                Si vous préférez déclarer explicitement tous les noms de
		domaines, utilisez le mode 'manual'. Une erreur sera enregistrée
		dans le journal si les noms ne correspondent pas à ceux
		attendus.

    Statut:Expérimental
    

    Module:mod_md
    

    
            
    
                Le protocole ACME propose deux méthodes pour vérifier à qui
		appartient le domaine via HTTP : la première utilise les URLs en
		"http:" (port 80) et la deuxième les URLs en "https:" (port
		443). Si votre serveur n'est accessible sur aucun
		de ces ports, ACME ne pourra fonctionner que si vous configurez
		votre serveur DNS de manière adéquate (voir la directive MDChallengeDns01).
            
    
                Sur la plupart des serveurs publics, "http:" arrive sur le
		port 80 et "https:" sur le port 443. Ce module vérifie les ports
		sur lesquels votre serveur Apache est en écoute et suppose
		qu'ils sont disponibles. Autrement dit, si votre serveur n'est
		pas en écoute sur le port 80, le module suppose que les requêtes
		en "http:" en provenance d'internet ne seront pas traitées.
            
    
		Ce raisonnement est légitime, mais il peut s'avérer faux.
		Par exemple, même si votre serveur est effectivement en écoute
		sur le port 80, votre pare-feu peut bloquer ce dernier. "http:"
		ne sera alors disponible que sur votre intranet. Dans ce cas, le
		module va supposer de manière erronée que Let's Encrypt peut
		effectuer des vérifications en "http:" avec votre serveur. Ces
		dernières échouerons car elles auront été rejetées par votre
		pare-feu.
            
    
            
    Exemple
    MDPortMap http:- https:8433
    

    
            
    
                L'exemple précédent montre comment spécifier que les requêtes en
		"http:" en provenance d'internet n'arriveront jamais. En outre,
		il indique que les requêtes en "https:" arriveront sur le port
		8433.
            
    
		Cette définition peut s'avérer nécessaire si vous faites de la
		redirection de port ; votre serveur peut ainsi être accessible
		depuis l' Internet sur le port 443, alors que le port local
		utilisé par httpd sera différent. Par exemple, votre serveur
		peut n'être en écoute que sur les ports 8443 et 8000, mais
		accessible depuis internet sur les ports 443 et 80.

                Cette directive permet de définir les paramètres de construction
		des clés privées pour les domaines gérés. Vous pouvez configurer
		plusieurs types de clés privées et le module obtiendra un
		certificat pour chaque clé.
            
    
                La recommandation actuelle (en 2017) est de 2048 bits au minimum,
		et une valeur inférieure ne sera pas acceptée. Des valeurs
		supérieures offriront une plus grande sécurité mais seront plus
		gourmandes en ressources, et augmenteront donc la charge de
		votre serveur, ce qui pourra (ou non) être gênant pour vous.
            
    
                D'autres types de clés seront supportés dans le futur.
		Vous pouvez par exemple configurer une clé RSA et une clé
		Elliptic Curve (EC) de façon à ce que deux certificats soient
		créés pour le domaine concerné. Lors d'une connexion avec un
		client, c'est la première clé supportée par ce dernier qui sera
		utilisée.
            
    
                Comme les clés et certificats EC sont plus petits, vous pouvez
		les proposer en premier pour tous les clients modernes
		compatibles, ce qui peut accélérer la phase de négociation.
		Ajoutez tout de même une clé RSA pour supporter les clients plus
		anciens.		
            
    
            
    Exemple
    MDPrivateKeys secp256r1 rsa3072
    

    
            
    
                Les types EC supportés dépendent du CA que vous utilisez. Par
		exemple, Let's encrypt supporte les courbes elliptiques
		'secp256r1' et 'secp384r1'.
            
    
                Chaque type de clé et certificat est stocké dans son fichier
		propre au sein de l'espace de stockage MD. Le type de clé
		constitue une partie du nom de fichier avec une convention de
		nommage présentant une compatibilité ascendante avec les
		certificats RSA. Vous pouvez ainsi continuer à partager ces
		fichiers avec les autres applications.
            
    
		
		Notez que cette directive n'aura d'effet que sur les nouvelles
		clés. Toute clé préexistante ne sera pas affectée. En outre,
		seules les clés privées générées pour les certificats sont
		concernées, les clés de comptes ACME n'étant pas affectées.

		par aucun serveur virtuel, le module n'effectuera aucune demande
		de renouvellement. De même, pour les domaines gérés avec des

		supposera que vous avez votre propre source et n'effectuera

            Normalement, les certificats ont une validité de 90 jours, et
	    mod_md les renouvelle lorsqu'il leur reste 33% de
	    durée de vie (soit 30 jours pour une durée de vie de 90 jours). Si
	    cela ne correspond pas à ce que vous souhaitez, vous pouvez
	    spécifier une autre valeur comme dans les exemples suivants :

MDRenewWindow 21d 
# 30 secondes (peut-être un peu juste !)
MDRenewWindow 30s
# lorsqu'il reste 10% de durée de vie au certificat
MDRenewWindow 10%
    

    
	    
    En mode pilotage automatique, le module va vérifier le statut des
	    domaines gérés au moins toutes les 12 heures pour voir s'il y a
	    quelque chose à faire. En cas d'erreur, par exemple lorsque le CA
	    est inaccessible, il va dans un premier temps réessayer après

    Cette directive facilite la migration de vos domaines gérés de

    Exemple

	    est sans risque et vous pouvez la désactiver à tout moment.
            
    
                Ce qui suit par contre, a des conséquences : si
		vous souhaitez que les clients n'utilisent plus
		d'URLs en http:, spécifiez :
            
    
            
    Permanent (pour au moins 6 mois !)
    MDRequireHttps permanent
    

    
            
    Cette directive a deux effets :
            
    
            
      
                
    1. Toutes les requêtes pour une ressource en http:
		sont redirigées vers la même requête en remplaçant le protocole
		http: par https: et en renvoyant le code
		d'état 301. Ce dernier indique aux clients que
		cette modification est permanente et qu'ils doivent mettre à
		jour leurs liens en conséquence.
                
      2. 
		
    2. Toutes les réponses aux requêtes en https:
		comporteront l'en-tête Strict-Transport-Security
		avec une durée de vie de six mois. Cela indique au navigateur
		qu'il ne devra jamais utiliser
		http: (pendant six mois) lorsqu'il formulera une
		requête pour le domaine concerné.  Avec cette information, les
		navigateurs refuseront de contacter votre site en mode non
		chiffré. Ceci interdit à des middlewares malicieux de dégrader
		les connexions et d'écouter/manipuler le trafic. C'est une bonne
		chose, mais cette configuration ne peut pas être désactivée
		aussi simplement que la configuration temporaire ci-dessus.
                
      3. 
            
    
            
    Vous pouvez obtenir le même résultat de manière simple avec
	    mod_alias et une configuration basée sur la
	    directive Redirect. Si
	    vous le faites vous-même, assurez-vous d'exclure les chemins
	    /.well-known/* de votre redirection, sinon mod_md
	    aura des difficultés pour signer les nouveaux certificats.
            
    
            
    Si vous effectuez cette configuration au niveau global, elle
	    s'appliquera à tous les domaines gérés. Si vous souhaitez qu'elle ne
	    s'applique qu'à un domaine spécifique, utilisez :

		de remplacer toute configuration d'agrafage au niveau de
		mod_ssl pour ce(s) domaine(s). Lorsqu'elle est désactivée,
		l'agrafage de mod_ssl se chargera du travail (s'il a été

		L'agrafage fonctionne aussi pour les domaines non gérés par
		mod_md (voir à ce sujet la directive MDStapleOthers). En fait, l'agrafage

    Directive MDStaplingRenewWindow
    

    

    Description:Contrôle l'ancienneté des réponses OCSP au dela de laquelle
	ces dernières seront renouvelées.
    

    Syntaxe:MDStaplingRenewWindow duration
    

    Défaut:MDStaplingRenewWindow 33%
    

    Contexte:configuration globale
    

    Statut:Expérimental
    

    Module:mod_md
    

    Compatibilité:Disponible à partir de la version 2.4.42 du serveur HTTP
	Apache
    

    
            
    
		Si la durée de validité d'un réponse OCSP passe en dessous de
		duration, mod_md va tenter de la
		renouveler.
            
    
                La CA à l'origine du certificat fournit aussi en général le
		service de réponse OCSP et détermine la durée de validité de sa
		réponse signée à propos de la validité du certificat. Plus
		longtemps une réponse sera valide, plus longtemps elle pourra
		être mise en cache, ce qui arrange tout le monde en matière de
		performances. Plus courte sera la validité d'une réponse, plus
		vite seront envoyées des révocations de certificats aux clients.
		Il est donc important de prendre en compte la qualité de
		service.
            
    
                En ajustant la durée de validité des réponses vous-même, vous
		pouvez contrôler une partie du processus. Si vous spécifiez une
		durée de vie importante (autrement dit si vous spécifiez un
		petit pourcentage de validité avant que l'information n'expire),
		vous assurer un temps de mise en cache maximal, mais une
		interruption du service OCSP (par exemple un arrêt pour
		maintenance) aura plus de chance de vous affecter. Si vous
		spécifiez un pourcentage de temps avant expiration plus
		important, les mises à jour seront plus fréquentes, ce qui va
		augmenter la charge de l'infrastructure de serveurs du CA et
		nécessiter d'avantage de coordination entre les processus
		enfants de votre propre serveur.
            
    
                La valeur par défaut choisie est de 33%, ce qui signifie que la
		demande de renouvellement interviendra lorsque la durée de vie
		de la réponse OCSP passera en dessous de 33%. Pour une CA qui
		fournit des réponses OCSP avec une durée de vie de 3 jours, cela
		implique 2 jours de mise en cache et 1 jour pour les tentatives
		de renouvellement. Pour affecter votre domaine, une interruption
		de service devra donc avoir une durée supérieure à 1 jour.
            
    
                Vous pouvez aussi définir de manière absolue la durée de vie
		restante, par exemple `2d` pour 2 jours.

    Directive MDStoreDir
    

    

    Description:Chemin dans le système de fichiers local du répertoire où
	seront stockées les données à propos des domaines gérés.
    

    Syntaxe:MDStoreDir path
    

    Défaut:MDStoreDir md
    

    Contexte:configuration globale
    

    Statut:Expérimental
    

    Module:mod_md
    

    
            
    
                Cette directive permet de définir le répertoire dans le système
		de fichiers local où seront stockées les données à propos des
		domaines gérés. Il s'agit d'un chemin absolu ou relatif à la
		racine du serveur. Par défaut, le répertoire "md" sera créé à la
		racine de votre serveur.
            
    
		Si vous souhaitez changer de répertoire et si ce dernier
		contient déjà des données, copiez tout d'abord les données vers
		le nouveau répertoire, puis modifier la configuration et
		redémarrez le serveur. Si vous commencez par modifier la
		configuration et redémarrer le serveur sans copier les données,
		ce dernier croira que les certificats sont absents et il tentera
		d'en obtenir de nouveaux.

    Directive MDWarnWindow
    

    

    Description:Définit la fenêtre de temps pendant laquelle vous serez
	informé de l'expiration prochaine d'un certificat.
    

    Syntaxe:MDWarnWindow duration
    

    Défaut:MDWarnWindow 10%
    

    Contexte:configuration globale
    

    Statut:Expérimental
    

    Module:mod_md
    

    
            
    
                Voir la directive MDRenewWindow pour une description
		de la méthode à employer pour spécifier cette durée.
            
    
                Le module inspecte la durée de vie restante des certificats et
		invoque MDMessageCmd
		lorsqu'une de ces durées devient inférieure à la fenêtre de
		temps spécifiée. Si l'on conserve la valeur par défaut, cette
		durée correspond à 9 jours pour les certificats de Let's
		Encrypt.
            
    
                Cette directive s'applique aussi aux domaines gérés via des
		fichiers de certificats statiques (voir la directive MDCertificateFile).

    Summary
    

    
    This module provides the handler send-as-is
    which causes Apache HTTP Server to send the document without adding most of
    the usual HTTP headers.
    

    
    This can be used to send any kind of data from the server,
    including redirects and other special HTTP responses, without
    requiring a cgi-script or an nph script.
    

    
    For historical reasons, this module will also process any
    file with the mime type httpd/send-as-is.

    Usage
    

    
    In the server configuration file, associate files with the
    send-as-is handler e.g.
    

    
    AddHandler send-as-is asis
    


    
    The contents of any file with a .asis extension
    will then be sent by Apache httpd to the client with almost no
    changes. In particular, HTTP headers are derived from the file
    itself according to mod_cgi rules, so an asis
    file must include valid headers, and may also use the CGI
    Status: header to determine the HTTP response
    code. The Content-Length: header will automatically
    be inserted or, if included, corrected by httpd.
    

    
    Here's an example of a file whose contents are sent as
    is so as to tell the client that a file has
    redirected.
    


    
    
      Status: 301 Now where did I leave that URL
    
      Location: http://xyz.example.com/foo/bar.html
    
      Content-type: text/html
    
      
    
      <html>
    
      <head>
    
      <title>Lame excuses'R'us</title>
    
      </head>
    
      <body>
    
      <h1>Fred's exceptionally wonderful page has moved to
    
      <a href="http://xyz.example.com/foo/bar.html">Joe's</a>
      site.
    
      </h1>
    
      </body>
    
      </html>
    
    

    
    Notes:
    
    
    The server always adds a Date: and Server:
    header to the data returned to the client, so these should not be
    included in the file. The server does not add a
    Last-Modified header; it probably should.

    CoreDumpDirectory Yönergesi
    

    

    Açıklama:core dosyasını dökümlemek üzere Apache HTTP
    Sunucusunun geçmeye çalışacağı dizin.
    

    Sözdizimi:CoreDumpDirectory dizin
    

    Öntanımlı:Öntanımlı değer için aşağıdaki açıklamaya bakınız
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:event, worker, prefork
    

    
    
    Bu yönerge core dosyasını dökümlemek üzere Apache httpd’nin
      geçmeye çalışacağı dizini belirler. Eğer işletim sisteminiz, çöken bir
      sürecin olması durumunda core dosyasını çöken sürecin
      çalışma dizinine yazacak şekilde yapılandırılmışsa,
      CoreDumpDirectory yönergesinin değeri olarak,
      öntanımlı olan ve sunucuyu çalıştıran kullanıcı tarafından yazılamayan
      ServerRoot dizini yerine başka bir
      çalışma dizini belirtmek gerekir.
    

    
    Hata ayıklamak amacıyla bir core dosyası dökümlemek
      isterseniz farklı bir yer belirtmek için bu yönergeyi
      kullanabilirsiniz. Eğer işletim sisteminiz çöken bir sürecin olması
      durumunda core dosyasını çöken sürecin çalışma dizinine
      yazacak şekilde yapılandırılmamışsa, bu yönergenin bir etkisi olmaz.
    

    
    
      
    Linux sistemleri için güvenlik bilgisi
    

      
    Bu yönergenin Linux'ta kullanılması, sistemdeki diğer işlemlerin
      (benzer yetkilerle çalıştırılan CGI komut dosyaları gibi) 
      ptrace sistem çağrısı yoluyla httpd çocuklarına eklenmesine 
      izin verebilir. Bu, bazı güvenlik saldırılarına karşı korumayı 
      zayıflatabilir. Bu yönergenin üretim sistemlerinde kullanılması 
      önerilmez.
    
    
    
    
    
    Linux üzerinde core dökümlemek
    
      
    Apache httpd root olarak başlatılıp başka bir kullanıcıya geçilirse
        Linux çekirdeği, süreç tarafından yazılabilir olsa bile
        core dökümlemeyi iptal eder. Eğer
        CoreDumpDirectory yönergesi ile açıkça bir
        dizin belirtirseniz, Apache httpd (2.0.46 ve sonraki sürümleri), Linux
        2.4 ve sonrasında core dökümlemeyi yeniden
        etkinleştirecektir.
    
    
    

    
    
    
    BSD üzerinde core dökümlemek
    
    
    BSD sistemlerinde (FreeBSD gibi) suid bitli çalıştırılabilirlerin
      core dökümlemesini etkin kılmak için
      kern.sugid_coredump değişkenine 1 değerini atayın.
    
    
    
    

    
    Özel sinyaller
    
      
    CoreDumpDirectory işlemi sadece belli
        sinyaller için gerçekleşir: SIGFPE, SIGILL, SIGABORT, SIGSEGV ve
        SIGBUS.
    
      
    Bazı işletim sistemlerinde SIGQUIT sinyali de bir core
        dosyası dökümler ancak bunu CoreDumpDirectory
        veya EnableExceptionHook işlemi üzerinden
        yapmaz, dolayısıyla core dosyasının yeri tamamen işletim
        sisteminin belirlediği yer olur.

    EnableExceptionHook Yönergesi
    

    

    Açıklama:Bir çöküş sonrası olağandışılık eylemcilerini çalıştıracak
  kancayı etkin kılar.
    

    Sözdizimi:EnableExceptionHook On|Off
    

    Öntanımlı:EnableExceptionHook Off
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:event, worker, prefork
    

    
    
    Güvenlik sebebiyle bu yönerge sadece Apache
      --enable-exception-hook seçeneği ile yapılandırılmışsa
      kullanılabilir olacaktır. Bu, harici modüllerin eklenmesine ve bir çocuk
      sürecin çöküşü sonrası bir şeyler yapmaya izin veren bir kancayı etkin
      kılar.
    

    
    Bu kancayı kullanan iki modül (mod_whatkilledus ve
    mod_backtrace) zaten vardır. bunlar hakkında daha fazla bilgi
      edinmek için Jeff Trawick'in EnableExceptionHook sitesine bakabilirsiniz.

    GracefulShutdownTimeout Yönergesi
    

    

    Açıklama:Sunucunun nazikçe kapatılmasının ardından ana süreç çıkana kadar
  geçecek süre için bir zaman aşımı belirler.
    

    Sözdizimi:GracefulShutdownTimeout saniye
    

    Öntanımlı:GracefulShutdownTimeout 0
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:event, worker, prefork
    

    Uyumluluk:Sürüm 2.2 ve sonrasında mevcuttur
    

    
    
    GracefulShutdownTimeout yönergesi, sunucuya
      "nazikçe dur" sinyali gönderildikten sonra mevcut bağlantılara hizmet
      sunmaya daha kaç saniye devam edebileceğini belirtir.
    

    
    Bu değerin 0 olarak belirtilmesi, sunucunun bekleyen bütün
      isteklere hizmet sunumu tamamlanıncaya kadar (gerekirse sonsuza kadar)
      bekleyebileceği anlamına gelir.
    


    

    top
    

    Listen Yönergesi
    

    

    Açıklama:Sunucunun dinleyeceği IP adresini ve portu belirler.
    

    Sözdizimi:Listen [IP-adresi:]port-numarası
  [protokol]
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    Uyumluluk:protokol değiştirgesi 2.1.5 sürümünde
    eklenmiştir.
    

    
    
    Listen yönergesi Apache httpd’yi sadece belli IP
      adreslerini ve portlarını dinlemeye sevkeder.
      Listen artık belirtilmesi zorunlu yönergelerden
      biridir. Yapılandırma dosyasında bulunmadığı takdirde sunucu
      başlatılırken başarısız olacaktır. Bu Apache HTTP Sunucusunun önceki
      sürümünde böyle değildi.
    

    
    Listen yönergesi Apache httpd’ye, sadece belli
      portlardan veya IP adresi ve port çiftlerinden gelen istekleri kabul
      etmesini söyler. Eğer sadece port numarası belirtilmişse sunucu
      belirtilen portu bütün ağ arabirimlerinde dinleyecektir. Eğer portla
      birlikte bir IP adresi de belirtilmişse, sunucu belirtilen portu sadece
      belirtilen arabirimden dinleyecektir.
    

    
    Çok sayıda IP adresi ve port belirtmek için çok sayıda
      Listen yönergesi kullanılabilir. Sunucu bu
      durumda belirtilen bütün IP adreslerinden ve portlardan gelecek
      isteklere yanıt verecektir.
    

    
    Örneğin sunucunun hem port 80 hem de port 8000’den istek kabul etmesini
      istiyorsanız bunu şöyle belirtebilirsiniz:
    

    
    Listen 80
Listen 8000
    


    
    Sunucunun belirtilen iki ağ arabiriminden ve port numarasından gelen
      bağlantıları kabul etmesi için şu yapılandırmayı kullanabilirsiniz:
    

    
    Listen 192.170.2.1:80
Listen 192.170.2.5:8000
    


    
    IPv6 adresleri belirtilirken örnekteki gibi köşeli ayraçlar arasına
      alınmalıdır:
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    


    
    İsteğe bağlı protocol argümanı çoğu yapılandırmada gerekli
      değildir. Belirtilmediği takdirde. port 443 için https ve
      tüm diğer portlar için http öntanımlıdır. Protokol, isteği
      hangi modülün elde edeceğinin ve AcceptFilter yönergesi ile protokole özgü
      hangi en iyilemelerin uygulanacağının saptanmasında kullanılır.
    

    
    Protokol belirtme ihtiyacını sadece standartdışı portlar
      çalıştırıyorsanız duyarsınız. Örneğin, port 8443 üzerinde bir
      https sitesi çalıştırmak istiyorsanız bunu şöyle
      belirtebilirsiniz:
    

    
    Listen 192.170.2.1:8443 https
    


    
    Hata durumu
    
      Aynı IP adresi ve portun çok sayıda Listen
      yönergesinde belirtilmesi bir "adres kullanımda" (Address already
      in use) hatasına yol açar.

    ListenBackLog Yönergesi
    

    

    Açıklama:Bekleyen bağlantılar kuyruğunun azami uzunluğunu
  belirler
    

    Sözdizimi:ListenBackLog kuyruk-uzunluğu
    

    Öntanımlı:ListenBackLog 511
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    
    
    Bekleyen bağlantılar kuyruğunun azami uzunluğu. Genellikle bu ayar ne
      gerekir ne de istenir. Ancak bazı sistemlerde TCP SYN yüklenme
      saldırılarına karşı bu değerin arttırılması gerekebilir.
      kuyruk-uzunluğu parametresi için listen(2)
      işlevinin açıklamasına bakınız.
    

    
    Bu değer çoğunlukla işletim sistemi tarafından daha küçük bir sayıyla
      sınırlanır. Bu, işletim sistemine bağlı olarak değişiklik gösterir.
      Ayrıca, çoğu işletim sisteminin kuyruk-uzunluğu parametresi
      ile ne belirttiğinize bakmaksızın kendisi için atanmış değeri (fakat
      normal olarak daha büyüğünü) kullanacağına dikkat ediniz.

    ListenCoresBucketsRatio Yönergesi
    

    

    Açıklama:İşlemci çekirdek sayısının dinleyenlerin buket sayısına oranı
    

    Sözdizimi:ListenCoresBucketsRatio oran
    

    Öntanımlı:ListenCoresBucketsRatio 0 (iptal)
    

    Bağlam:sunucu geneli
    

    Durum:MPM
    

    Modül:event, worker, prefork
    

    Uyumluluk:Apache HTTP Server 2.4.17 ve sonrasında,
 SO_REUSEPORT soket seçeneğini destekleyen bir Linux çekirdeğinin
 varlığında ve yeni bağlantıların bunu kullanan dinleme süreçlerinin (veya
 evrelerinin) soketleri arasında eşit paylaştırılıyor olması halinde
 kullanılır. Örneğin Linux 3.9 ve sonrasında kullanılabilirken *BSD'lerin şu
 anki SO_REUSEPORT gerçeklenimi ile kullanılamaz.
    

    
    
    (çevrimiçi) İşlemci çekirdek sayısının dinleyenlerin buket sayısına
      oranı, Apache HTTP Sunucusunun işlemci_çekirdek_sayısı /
      oran sayıda dinleme buketi oluşturması için kullanılabilir ve bu
      buketlerin herbiri aynı portlar üzerinde kendi Listen soketlerini içeriyor olurlar. 
      Bu durumda, her çocuk süreç tek bir buketle çalışır (çocukların 
      oluşturulması sırasında buketler döner dağılımla eşleştirilir).
    

    
    "çevrimiçi" İşlemci çekirdek sayısının anlamı
    
    
    Linux için (ve ayrıca BSD) bir işlemci çekirdeği Hotplug yapılandırılarak açılıp kapatıalbilir. 
      Dolayısıyla, ListenCoresBucketsRatio yönergesi 
      oluşturulacak buket sayısını hesaplarken bu yapılandırmayı esas alır.
    
    
    

    
    ListenCoresBucketsRatio yeni bağlantılar kabul
      edilirken/darboğazlar oluşurken ölçeklenebilirliği arttırabilir. Çok
      sayıda işlemci çekirdekli sistemlerde bu özelliğin etkinleştirilmesinin
      önemli başarım artışları ve daha kısa yanıt süreleri oluşturduğu
      gözlenmiştir.
    

    
    Bu oranın etkin olabilmesi için işlemci çekirdeği çift sayıda
      olmalıdır. oran için önerilen değer 8 olup bu
      durumda çalışma anında en azından 16 çekirdek
      kullanılabiliyor olmalıdır. En iyi başarımı elde etmek gereken 
      oran her sistem için hesaplanmalı, çok sayıda değer denenmeli 
      ve başlıca başarım ölçütlerinizin çeşitli sonuçları iyi gözlemlenmelidir. 
      
    
      
    
    Bu yönerge aşağı yuvarlanan    
      MinSpareThreads ve 
      MaxSpareThreads değerlerinin 
      hesabını etkiler. Bağlantıları en uygun şekilde kabul etmek için çocuk 
      süreçlerin sayısının buket sayısının katları olması gerekir.
    

    
    
    
    Çok sayıda Listen veya aynı adres veya port 
      üstünda çok sayıda Apache HTTP sunucusu
    
    
    Dinleyen soketler üzerinde SO_REUSEPORT seçeneğini tanımlamak 
      normal bir durumda sistem tarafından oluşturulmuş bir bağlama hatası 
      olmaksızın çok sayıda sürecin aynı adres ve porta bağlanması sonucunu 
      doğurur.
    
    
    Bu ayrıca pozitif bir ListenCoresBucketsRatio 
      değeriyle aynı IP:port üzerinde yapılandırılmış çok sayıda 
      Apache httpd örneğinin hatasız başlamasının yanında gelen çağrıların her 
      iki örneğe eşit olarak dağıtılacağı anlamına da gelir. (Bu, 
      herhangi bir durumda bir öneri veya makul bir kullanım DEĞİL, böyle bir 
      olası sorunun algılanmasının engelleneceğine dair bir uyarıdır.)
    
    
    Aynı örnek dahilinde, çok sayıda Listen 
      yönergesinin tam olarak aynı IP ve port üzerinde yapılandırılması durumunda 
      Apache httpd gerekli sınamaları yaptıktan sonra başlamayacak, böylelikle 
      birbirinin benzeri çok sayıda kullanışsız buketin oluşturulması 
      engellenecektir. Ancak, olası tüm örtüşmeler (bir konak adının başka bir 
      yerde kullanılmış bir IP'ye çözümlenmesi gibi) yakalanamayacaktır.

    MaxRequestWorkers yönergesi aynı anda işleme
      sokulacak bağlantı sayısını sınırlamak için kullanılır. MaxRequestWorkers bağlantı isteğinden fazlası geldiği
      takdirde bu istekler normal olarak kuyruğa alınıp bekletilir. Kuyrukta
      bekletilecek isteklerin azami sayısı ise ListenBacklog yönergesi ile belirlenir. İstek sunmakta olan
      çocuk süreçlerden biri serbest kaldığında bekletilen bağlantılardan
      birine hizmet sunulmaya başlanır.
    

    
    Evreli olmayan sunucularda (prefork gibi)
      MaxRequestWorkers yönergesi istekleri sunmak için
      başlatılacak çocuk süreçlerin azami sayısını belirler. Öntanımlı değer
      256 olup bu değeri arttırmak isterseniz ServerLimit değerini de

      yönergesi istemcilere hizmet verecek evre sayısını sınırlar. Öntanımlı
      değer melez MPM’ler için 16'dır
      (ServerLimit ile ThreadsPerChild çarpılır: 16 x
      25). Bu bakımdan MaxRequestWorkers değerini
      16 süreçten fazlasına ayarlamak için ServerLimit değerini de arttırmalısınız.

      bağlantılarını elde eden evreler ve bu bağlantıları işlemekte yardımcı
      olan modül çağrıları tarafından kullanılan yığıtın bayt cinsinden
      uzunluğunu belirler. Çoğu durumda işletim sistemi yığıtı uygun bir
      boyuta ayarlar, fakat yine de ayarlanmasını gerektirecek bazı durumlar
      olabilir:
    

    
      
      
    • HP-UX gibi görece küçük yığıt boyuna sahip platformlarda, Apache
        httpd, görece büyük yığıt alanı kullanan bazı üçüncü parti modüller
        yüzünden çökebilir. Bu modüller öntanımlı yığıt boyu daha büyük olan
        diğer platformlarda sorunsuz çalışabilir. Bu tür çökmeler
        ThreadStackSize yönergesine daha büyük yığıt
        boyu atanarak çözümlenir. Böyle bir ayarlamayı sadece üçüncü parti
        modülün üreticisi bunun gerekliliğini belirtmişse veya Apache httpd’nin
        evre yığıt boyutunun küçüklüğünden dolayı çöktüğü teşhis edildiği
        takdirde yapınız.
      • 

      
    • Öntanımlı yığıt boyu Apache sunucusu için gerekenden belirgin
        şekilde büyük bazı platformalarda, eğer
        ThreadStackSize yönergesi ile bu boyuttan daha
        düşük bir değer atanmışsa çocuk süreç başına evre sayısının yüksek
        olduğu durumlarda bu yığıt yetmeyebilir. Böyle bir ayarlama sadece
        sunucunun öldüresiye denendiği dolayısıyla yığıt boyutlarının aşırı
        zorlandığı deneme ortamlarında yapılmalıdır. Gereken en küçük yığıt
        boyutu kullanılan modüle sıkı sıkıya bağlıdır, fakat Apache httpd
        yapılandırmasında yapılan bir değişiklik mevcut
        ThreadStackSize ayarını geçersiz hale
        getirebilir.
      • 

      
    • Linux üzerinde, ilgili sistem çağrısı en küçük yığıt boyutu
        olarak bu değeri kullanacağından, bu yönerge sadece öntanımlı yığıt
        boyutunu arttırmak için kullanılabilir. ulimit -s  için
        (çoğunlukla büyükçe) soft sınır (sınırsızsa 8MB), öntanımlı yığıt
        boyutu olarak kullanılır.
      • 
    
    

    
    Çocuk süreç başına yüksek bir evre sayısı gerekmedikçe
      ThreadStackSize değerinin azaltılmaması önerilir.
      Bazı platformlarda (Linux dahil), 128000 ayarı zaten çok düşüktür ve daha
      da azaltmak bazı modüllerle çökmeye sebep olur.

    概要
    

    
    このモジュールはハンドラ send-as-is
    を提供します。このハンドラは通常の HTTP
    ヘッダをほとんど追加することなくドキュメントを送信します。
    

    
    これはサーバからどんな種類のデータを送るときにも使用できます。
    Cgi スクリプトや nph スクリプトが無くてもリダイレクトや他の特別な
    HTTP 応答を送ることができます。
    

    
    歴史的な理由により、このモジュールは mime タイプ
    httpd/send-as-is のファイルも処理します。

    使用法
    

    
    サーバ設定ファイルで、ファイルと send-as-is
    ハンドラを例えば以下のように関連付けてください。
    

    
    AddHandler send-as-is asis
    

    
    拡張子が .asis のすべてのファイルの内容は Apache
    からクライアントへほとんど変更無く送られます。
    HTTP ヘッダは特別で、ファイルから mod_cgi
    のルールに従って取り出されます。ですから asis ファイルには
    正しいヘッダが記載されていなければなりませし、
    また CGI での表記法であるところの Status: ヘッダを使って
    HTTP レスポンスコードを決めることもできます。
    

    
    これはクライアントにファイルが移動したことを知らせるために
    as is (そのまま) で送られるファイルの内容の例です。
    
    


    
    
      Status: 301 Now where did I leave that URL
    
      Location: http://xyz.abc.com/foo/bar.html
    
      Content-type: text/html
    
      
    
      <html>

      </head>
    
      <body>
    
      <h1>Fred's exceptionally wonderful page has moved to
    
      <a href="http://xyz.abc.com/foo/bar.html">Joe's</a>
      site.
    
      </h1>
    
      </body>
    
      </html>
    
    

    
    注意
    
    
    注意: サーバはクライアントに返されるデータに常に Date:
    と Server: ヘッダを追加しますので、
    それらがファイルに書かれていてはいけません。
    サーバは Last-Modified ヘッダを追加しません。
    おそらくはそうすべきでしょうけれど。

    Apache Module mod_macro

    Description:Provides macros within apache httpd runtime configuration files
    

    Status:Base
    

    Module Identifier:macro_module
    

    Source File:mod_macro.c
    

    Compatibility:Available in httpd 2.4.5 and later
    

    Summary
    


    
    Provides macros within Apache httpd runtime configuration files,
    to ease the process of creating numerous similar configuration
    blocks. When the server starts up, the macros are expanded using the
    provided parameters, and the result is processed as along with the
    rest of the configuration file.
    


    


    top
    

    

    Usage
    


    Macros are defined using <Macro> blocks, which contain the portion of
your configuration that needs to be repeated, complete with variables
for those parts that will need to be substituted.
    


    For example, you might use a macro to define a <VirtualHost> block, in order to define
multiple similar virtual hosts:
    


    <Macro VHost $name $domain>
<VirtualHost *:80>
    ServerName $domain
    ServerAlias www.$domain

    DocumentRoot "/var/www/vhosts/$name"
    ErrorLog "/var/log/httpd/$name.error_log"
    CustomLog "/var/log/httpd/$name.access_log" combined
</VirtualHost>
</Macro>
    



    Macro names are case-insensitive, like httpd configuration
directives. However, variable names are case sensitive.
    


    You would then invoke this macro several times to create virtual
hosts:
    


    Use VHost example example.com
Use VHost myhost hostname.org
Use VHost apache apache.org

UndefMacro VHost
    



    At server startup time, each of these Use
invocations would be expanded into a full virtualhost, as
described by the <Macro>
definition.
    


    The UndefMacro directive is
used so that later macros using the same variable names don't result in
conflicting definitions.
    


    A more elaborate version of this example may be seen below in the
Examples section.
    


    top
    

    

    Tips
    


    Parameter names should begin with a sigil such as $,
%, or @, so that they are clearly
identifiable, and also in order to help deal with interactions with
other directives, such as the core Define directive. Failure to do so will
result in a warning. Nevertheless, you are encouraged to have a good
knowledge of your entire server configuration in order to avoid reusing
the same variables in different scopes, which can cause confusion.
    


    Parameters prefixed with either $ or % are
not escaped. Parameters prefixes with @ are escaped in
quotes.
    


    Avoid using a parameter which contains another parameter as a prefix,
(For example, $win and $winter) as this may
cause confusion at expression evaluation time. In the event of such
confusion, the longest possible parameter name is used.
    


    If you want to use a value within another string, it is useful to
surround the parameter in braces, to avoid confusion:
    


    <Macro DocRoot ${docroot}>
    DocumentRoot "/var/www/${docroot}/htdocs"
</Macro>
    



    top
    

    

    Examples
    



    Virtual Host Definition
    



    A common usage of mod_macro is for the creation of
dynamically-generated virtual hosts.
    


    ## Define a VHost Macro for repetitive configurations

<Macro VHost $host $port $dir>
  Listen $port
  <VirtualHost *:$port>

    ServerName $host
    DocumentRoot "$dir"

    # Public document root
    <Directory "$dir">
        Require all granted
    </Directory>

    # limit access to intranet subdir.
    <Directory "$dir/intranet">
      Require ip 10.0.0.0/8
    </Directory>
  </VirtualHost>
</Macro>

## Use of VHost with different arguments.

Use VHost www.apache.org 80 /vhosts/apache/htdocs
Use VHost example.org 8080 /vhosts/example/htdocs
Use VHost www.example.fr 1234 /vhosts/example.fr/htdocs
    

 


    Removal of a macro definition
    



    It's recommended that you undefine a macro once you've used it. This
avoids confusion in a complex configuration file where there may be
conflicts in variable names.
    


    <Macro DirGroup $dir $group>
  <Directory "$dir">
    Require group $group
  </Directory>
</Macro>

Use DirGroup /www/apache/private private
Use DirGroup /www/apache/server  admin

UndefMacro DirGroup

    The <Macro> directive controls the
    definition of a macro within the server runtime configuration files.
    The first argument is the name of the macro.
    Other arguments are parameters to the macro. It is good practice to prefix
    parameter names with any of '$%@', and not macro names
    with such characters.
    
    

    
    <Macro LocalAccessPolicy>
    Require ip 10.2.16.0/24

    Status:Base
    

    Module:mod_macro
    

    
    
    The Use directive controls the use of a macro.
    The specified macro is expanded. It must be given the same number of
    arguments as in the  macro definition. The provided values are
    associated to their corresponding initial parameters and are substituted
    before processing.
    

    
    Use LocalAccessPolicy

Use RestrictedAccessPolicy "192.54.172.0/24 192.54.148.0/24"
    


    
    is equivalent, with the macros defined above, to:
    

    
    Require ip 10.2.16.0/24
...
Require ip 192.54.172.0/24 192.54.148.0/24

mod_status - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4
    

    

    <-
    


    

    Apache Module mod_status
    

    

    Available Languages:  en  |
 fr  |
 ja  |
 ko  |
 tr 
    

    

    Description:Provides information on server activity and
performance
    

    Status:Base
    

    Module Identifier:status_module
    

    Source File:mod_status.c
    

    Summary
    

    
    The Status module allows a server administrator to find out
    how well their server is performing. A HTML page is presented
    that gives the current server statistics in an easily readable
    form. If required this page can be made to automatically
    refresh (given a compatible browser). Another page gives a
    simple machine-readable list of the current server state.
    

    
    The details given are:
    

    
      
      
    • The number of workers serving requests
      • 

      
    • The number of idle workers
      • 

      
    • The status of each worker, the number of requests that
      worker has performed and the total number of bytes served by
      the worker (*)
      • 

      
    • A total number of accesses and byte count served (*)
      • 

      
    • The time the server was started/restarted and the time it
      has been running for
      • 

      
    • Averages giving the number of requests per second, the
      number of bytes served per second and the average number of
      bytes per request (*)
      • 

      
    • The current percentage CPU used by each worker and in
      total by all workers combined (*)
      • 

      
    • The current hosts and requests being processed (*)
      • 
    
    

    
    The lines marked "(*)" are only available if
    ExtendedStatus
    is On.  In version 2.3.6, loading mod_status will
    toggle ExtendedStatus On
    by default.
    

    


    top
    

    

    Enabling Status Support
    
    

    
    To enable status reports only for browsers from the example.com
    domain add this code to your httpd.conf
    configuration file
    

    <Location "/server-status">
    SetHandler server-status
    Require host example.com
</Location>
    


    
    You can now access server statistics by using a Web browser
    to access the page
    http://your.server.name/server-status
    

    top
    

    

    Automatic Updates
    

    
    
    You can get the status page to update itself automatically if
    you have a browser that supports "refresh". Access the page
    http://your.server.name/server-status?refresh=N to
    refresh the page every N seconds.
    


    top
    

    

    Machine Readable Status File
    

    
    
    A machine-readable version of the status file is available by
    accessing the page
    http://your.server.name/server-status?auto. This
    is useful when automatically run, see the Perl program
    log_server_status, which you will find in the
    /support directory of your Apache HTTP Server installation.
    

    
    
      It should be noted that if mod_status is
      loaded into the server, its handler capability is available
      in all configuration files, including
      per-directory files (e.g.,
      .htaccess). This may have security-related
      ramifications for your site.
    
    


    top
    

    

    Using server-status to troubleshoot
    
    

    
    The server-status page may be used as a starting
    place for troubleshooting a situation where your server is consuming
    all available resources (CPU or memory), and you wish to identify
    which requests or clients are causing the problem.
    

    
    First, ensure that you have ExtendedStatus set on, so that you can see
    the full request and client information for each child or
    thread.
    

    
    Now look in your process list (using top, or similar
    process viewing utility) to identify the specific processes that are
    the main culprits. Order the output of top by CPU
    usage, or memory usage, depending on what problem you're trying to
    address.
    

    
    Reload the server-status page, and look for those process
    ids, and you'll be able to see what request is being served by that
    process, for what client. Requests are transient, so you may need to
    try several times before you catch it in the act, so to speak.
    

    
    This process should give you some idea what client, or
    what type of requests, are primarily responsible for your load
    problems. Often you will identify a particular web application that
    is misbehaving, or a particular client that is attacking your
    site.

    Description:Enhanced charset/internationalisation support for libxml2-based
filter modules
    

    Status:Base
    

    Module Identifier:xml2enc_module
    

    Source File:mod_xml2enc.c
    

    Compatibility:Version 2.4 and later.  Available as a third-party module
for 2.2.x versions
    

    Summary
    

    
    This module provides enhanced internationalisation support for
    markup-aware filter modules such as mod_proxy_html.
    It can automatically detect the encoding of input data and ensure
    they are correctly processed by the libxml2 parser, including converting to Unicode (UTF-8) where
    necessary.  It can also convert data to an encoding of choice
    after markup processing, and will ensure the correct charset
    value is set in the HTTP Content-Type header.
    

    


    top
    

    

    Usage
    
    
    There are two usage scenarios: with modules programmed to work
    with mod_xml2enc, and with those that are not aware of it:
    
    
    
    
    Filter modules enabled for mod_xml2enc
    
    
    Modules such as mod_proxy_html version 3.1
    and up use the xml2enc_charset optional function to retrieve
    the charset argument to pass to the libxml2 parser, and may use the
    xml2enc_filter optional function to postprocess to another
    encoding.  Using mod_xml2enc with an enabled module, no configuration
    is necessary: the other module will configure mod_xml2enc for you
    (though you may still want to customise it using the configuration
    directives below).
    
    
    
    
    Non-enabled modules
    
    
    To use it with a libxml2-based module that isn't explicitly enabled for
    mod_xml2enc, you will have to configure the filter chain yourself.  So to
    use it with a filter foo provided by a module
    mod_foo to improve the latter's i18n support with HTML and
    XML, you could use
    
    
    
    FilterProvider iconv    xml2enc Content-Type $text/html
    FilterProvider iconv    xml2enc Content-Type $xml
    FilterProvider markup   foo Content-Type $text/html
    FilterProvider markup   foo Content-Type $xml
    FilterChain     iconv markup
    
    
    
    mod_foo will now support any character set supported by either
    (or both) of libxml2 or apr_xlate/iconv.
    
    
    

    top
    

    

    Programming API
    
    
    Programmers writing libxml2-based filter modules are encouraged to
    enable them for mod_xml2enc, to provide strong i18n support for your
    users without reinventing the wheel.  The programming API is exposed in
    mod_xml2enc.h, and a usage example is
    mod_proxy_html.
    

    top
    

    

    Detecting an Encoding
    
    
    Unlike mod_charset_lite, mod_xml2enc is designed
    to work with data whose encoding cannot be known in advance and thus
    configured.  It therefore uses 'sniffing' techniques to detect the
    encoding of HTTP data as follows:
    
    
      
        
    1. If the HTTP Content-Type header includes a
        charset parameter, that is used.
      2. 
        
    2. If the data start with an XML Byte Order Mark (BOM) or an
        XML encoding declaration, that is used.
      3. 
        
    3. If an encoding is declared in an HTML <META>
        element, that is used.
      4. 
        
    4. If none of the above match, the default value set by
        xml2EncDefault is used.
      5. 
    
    
    
    The rules are applied in order.  As soon as a match is found,
    it is used and detection is stopped.
    

    top
    

    

    Output Encoding
    

    libxml2 always uses UTF-8 (Unicode)
internally, and libxml2-based filter modules will output that by default.
mod_xml2enc can change the output encoding through the API, but there
is currently no way to configure that directly.
    

    Changing the output encoding should (in theory, at least) never be
necessary, and is not recommended due to the extra processing load on
the server of an unnecessary conversion.
    

    top
    

    

    Unsupported Encodings
    

    If you are working with encodings that are not supported by any of
the conversion methods available on your platform, you can still alias
them to a supported encoding using xml2EncAlias.
    

    

    top
    

    xml2EncAlias Directive
    

    

    Description:Recognise Aliases for encoding values
    

    Syntax:xml2EncAlias charset alias [alias ...]
    

    Context:server config
    

    Status:Base
    

    Module:mod_xml2enc
    

    
    
    This server-wide directive aliases one or more encoding to another
    encoding.  This enables encodings not recognised by libxml2 to be handled
    internally by libxml2's encoding support using the translation table for
    a recognised encoding.  This serves two purposes: to support character sets
    (or names) not recognised either by libxml2 or iconv, and to skip
    conversion for an encoding where it is known to be unnecessary.
    


    

    top
    

    xml2EncDefault Directive
    

    

    Description:Sets a default encoding to assume when absolutely no information
can be automatically detected
    

    Syntax:xml2EncDefault name
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Base
    

    Module:mod_xml2enc
    

    
    
    If you are processing data with known encoding but no encoding
    information, you can set this default to help mod_xml2enc process
    the data correctly.  For example, to work with the default value
    of Latin1 (iso-8859-1) specified in HTTP/1.0, use:
    
    
    xml2EncDefault iso-8859-1
    



    

    top
    

    xml2StartParse Directive
    

    

    Description:Advise the parser to skip leading junk.
    

    Syntax:xml2StartParse element [element ...]
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Base
    

    Module:mod_xml2enc
    

    
    
    Specify that the markup parser should start at the first instance
    of any of the elements specified.  This can be used as a workaround
    where a broken backend inserts leading junk that messes up the parser (example here).
    
    
    It should never be used for XML, nor well-formed HTML.

    Apache HTTP Server Version 2.4
    

    

    <-
    


    

    Apache Module mod_allowmethods
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Easily restrict what HTTP methods can be used on the server
    

    Status:Experimental
    

    Module Identifier:allowmethods_module
    

    Source File:mod_allowmethods.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    


    This module makes it easy to restrict what HTTP methods can be
used on a server. The most common configuration would be:
    


    <Location "/">
   AllowMethods GET POST OPTIONS
</Location>
    



    



    top
    

    AllowMethods Directive
    

    

    Description:Restrict access to the listed HTTP methods
    

    Syntax:AllowMethods reset|HTTP-method
[HTTP-method]...
    

    Default:AllowMethods reset
    

    Context:directory
    

    Status:Experimental
    

    Module:mod_allowmethods
    

    


    The HTTP-methods are case sensitive and are generally, as per
RFC, given in upper case. The GET and HEAD methods are treated as
equivalent. The reset keyword can be used to
turn off mod_allowmethods in a deeper nested context:
    


    <Location "/svn">
   AllowMethods reset
</Location>
    



    Caution
    
  
    The TRACE method cannot be denied by this module;
  use TraceEnable instead.
    

    


    mod_allowmethods was written to replace the rather
kludgy implementation of Limit and
LimitExcept.

    説明:スレッドを使わず、先行して fork を行なうウェブサーバを実装

    

    ステータス:MPM
    

    モジュール識別子:mpm_prefork_module
    

    ソースファイル:prefork.c
    

    概要
    

    
    このマルチプロセッシングモジュール (MPM) は、
    Unix 上での Apache 1.3 のデフォルトの挙動と非常によく似た方法で
    リクエストを処理する、スレッドを使わず、先行して fork を行なう
    ウェブサーバを実装しています。
    スレッドセーフでないライブラリとの互換性をとるために、
    スレッドを避ける必要のあるサイトでは、このモジュールの使用が適切でしょう。
    あるリクエストで発生した問題が他のリクエストに影響しないように、
    個々のリクエストを単離するのにも、最適な MPM です。
    

    
    この MPM は非常に自律的なので、この MPM の設定ディレクティブを
    調整する必要はほとんどないでしょう。もっとも重要なことは、
    MaxClients
    が、予想される同時リクエスト数を十分扱えるぐらいは大きいけれども、
    全プロセスに十分な物理メモリが確実に行き渡る程度には小さい値にする、
    ということです。

    動作方法
    
    
    一つのコントロールプロセスが、
    コネクションに対して listen して、しかるべき時に応答する
    子プロセスを起動します。Apache は常に幾つかのスペア
    かアイドルなサーバプロセスを維持していて、それらは入ってきた
    リクエストに応答できるように待機しています。
    このようにしてクライアントは、リクエストが応答される前に、
    新しい子プロセスが fork されるのを待たなくてもよいように
    なっています。
    

    
    親プロセスがリクエストに応答するの子プロセスを
    どのように生成するかは、
    StartServers,
    MinSpareServers,
    MaxSpareServers,
    MaxClients
    で調整します。一般的に、Apache は非常に自律的なので、
    大抵のサイトではこれらのディレクティブをデフォルト値から調整する
    必要はないでしょう。
    同時に 256 を超えるリクエストに応答しないといけないサイトでは、
    MaxClients
    を増やす必要があるでしょう。
    一方、メモリの限られているサイトでは、スラッシング
    (メモリとディスク間で何度もスワップ) が起こるのを防ぐために
    MaxClients
    を減らす必要があるでしょう。プロセス生成のチューニングに関する
    詳しい情報は、性能に関するヒント
    にあります。
    

    
    通常 Unix では親プロセスは 80 番ポートにバインドするために
    root で起動されますが、子プロセスやスレッドは
    もっと低い権限のユーザで Apache によって起動されます。
    User と
    Group
    ディレクティブは
    Apache の子プロセスの権限を設定するのに用いられます。
    子プロセスはクライアントに送るコンテンツ全てを読めないといけませんが、
    可能な限り必要最小限の権限のみを持っているようにするべきです。
    

    
    MaxRequestsPerChild
    は、古いプロセスを停止して新しいプロセスを起動することによって、
    どの程度の頻度でサーバがプロセスをリサイクルするかを制御します。

    親プロセスは超過プロセスを kill します。
    

    
    非常に混んでいるサイトでのみ、このパラメータをチューニングするべきです。
    このパラメータを大きくするということは、大抵の場合は悪い発想です。

    Apache Module mod_info
    

    

    Available Languages:  en  |

    Description:Provides a comprehensive overview of the server
configuration
    

    Status:Extension
    

    Module Identifier:info_module
    

    Source File:mod_info.c
    

    Summary
    

    
    To configure mod_info, add the following to your
    httpd.conf file.
    

    
    <Location "/server-info">
    SetHandler server-info
</Location>
    


    
    You may wish to use mod_authz_host inside the
    <Location>
    directive to limit access to your server configuration
    information:
    

    
    <Location "/server-info">
    SetHandler server-info
    Require host example.com
</Location>
    


    
    Once configured, the server information is obtained by
    accessing http://your.host.example.com/server-info
    

    


    top
    

    

    Security Issues
    
    
    Once mod_info is loaded into the server, its
    handler capability is available in all configuration
    files, including per-directory files (e.g.,
    .htaccess). This may have security-related
    ramifications for your site.
    

    
    In particular, this module can leak sensitive information
    from the configuration directives of other Apache modules such as
    system paths, usernames/passwords, database names, etc. Therefore,
    this module should only be
    used in a controlled environment and always with caution.
    

    
    You will probably want to use mod_authz_host
    to limit access to your server configuration information.
    

    
    Access control
    <Location "/server-info">
    SetHandler server-info
    # Allow access from server itself
    Require ip 127.0.0.1

    # Additionally, allow access from local workstation
    Require ip 192.168.1.17
</Location>
    

    

    top
    

    

    Selecting the information shown
    
    
    By default, the server information includes a list of
    all enabled modules, and for each module, a description of
    the directives understood by that module, the hooks implemented
    by that module, and the relevant directives from the current
    configuration.
    

    
    Other views of the configuration information are available by
    appending a query to the server-info request. For
    example, http://your.host.example.com/server-info?config
    will show all configuration directives.
    

    
    
        
    ?<module-name>
    
            
    Only information relevant to the named module
    
        
    ?config
    
            
    Just the configuration directives, not sorted by module
    
        
    ?hooks
    
            
    Only the list of Hooks each module is attached to
    
        
    ?list
    
            
    Only a simple list of enabled modules
    
        
    ?server
    
            
    Only the basic server information
    
        
    ?providers
    
            
    List the providers that are available on your server
    
    
    

    top
    

    

    Dumping the configuration on startup
    
    
    If the config define -DDUMP_CONFIG is set,
    mod_info will dump the pre-parsed configuration to
    stdout during server startup.
    

    
    httpd -DDUMP_CONFIG -k start
    

    
    
    Pre-parsed means that directives like
    <IfDefine> and
    <IfModule> are
    evaluated and environment variables are replaced. However it does
    not represent the final state of the configuration. In particular,
    it does not represent the merging or overriding that may happen
    for repeated directives.
    

    
    This is roughly equivalent to the ?config query.
    

    top
    

    

    Known Limitations
    
    
    mod_info provides its information by reading the
    parsed configuration, rather than reading the original configuration
    file. There are a few limitations as a result of the way the parsed
    configuration tree is created:
    
    
      
      
    • Directives which are executed immediately rather than being

    Sommaire
    


    
    Ce module fournit un identifiant dont l'unicité est garantie
    parmi "toutes" les requêtes sous des conditions très précises.
    L'identifiant unique le sera aussi parmi plusieurs machines
    appartenant à un cluster correctement configuré. L'identifiant est
    affecté à la variable d'environnement UNIQUE_ID pour
    chaque requête. Les identifiants uniques sont utiles pour diverses
    raisons dont la nature se situe au delà de la portée de ce
    document.

    Théorie
    
    

    
    Tout d'abord un bref rappel de la manière dont le serveur Apache
    fonctionne sous Unix (cette fonctionnalité n'étant actuellement pas
    supportée sous Windows NT). Sous Unix, Apache crée plusieurs
    processus enfants, ces derniers traitant les requêtes une par une.
    Chaque processus enfant peut traiter plusieurs requêtes pendant sa
    durée de vie. Dans le cadre de cette discussion, nous supposerons
    que les différents processus enfants ne s'échangent pas de données
    entre eux. Nous nous référerons aux processus enfants sous le nom de
    processus httpd.
    

    
    Votre site web est réparti entre une ou plusieurs machines dont
    vous êtes l'administrateur, et que nous nommerons cluster de
    serveurs. Chaque serveur peut exécuter plusieurs instances d'Apache.
    L'ensemble de ces dernières sera considéré comme "l'Univers", et
    sous certaines hypothèses, nous montrerons qu'il est possible dans
    cet univers, de générer des identifiants uniques pour chaque
    requête, sans pour autant nécessiter une communication importante
    entre les différents serveurs du cluster.
    

    
    Les machines de votre cluster doivent satisfaire ces conditions
    (même si le cluster ne comporte qu'une machine, vous devez
    synchroniser son horloge avec NTP) :
    

    
      
      
    • Les temps des machines sont synchronisés via NTP ou tout autre
      protocole de synchronisation du temps en réseau.
      • 

      
    • Les nom d'hôtes des machines sont tous différents, de façon à
      ce que le module puisse recevoir une adresse IP différente pour
      chaque machine du cluster en effectuant une recherche sur le nom
      d'hôte.
      • 
    
    

    
    Au vu des caractéristiques actuelles du système d'exploitation,
    nous supposerons que les pids (identifiants processus) sont codés
    sur 32 bits. Si le système d'exploitation utilise plus de 32 bits
    pour un pid, la correction est triviale mais doit être effectuée
    dans le code.
    

    
    Ces hypothèses posées, à un instant donné, nous pouvons
    distinguer tout processus httpd sur toute machine du cluster de tous
    les autres processus httpd. Pour ce faire, il suffit d'utiliser
    l'adresse IP de la machine et le pid du processus httpd. Un
    processus httpd peut traiter plusieurs requêtes simultanément si
    vous utilisez un module MPM multi-threadé. Pour identifier les
    threads, Apache httpd utilise en interne un index de threads. Ainsi,
    afin de générer des identifiants uniques pour chaque requête, il
    suffit d'effectuer une distinction en fonction du temps.
    

    
    Pour déterminer le temps, nous utiliserons un repère de temps
    Unix (les secondes écoulées depuis le 1er janvier 1970 UTC), et un
    compteur 16 bits. La précision du repère de temps n'étant que d'une
    seconde, le compteur va représenter 65536 valeurs par seconde. Le
    quadruplet (adresse IP, pid, repère de temps, compteur) est
    en mesure de distinguer 65536 requêtes par seconde par processus
    httpd. Il peut cependant arriver que le même pid soit réutilisé au
    cours du temps, et le compteur est là pour pallier cet
    inconvénient.
    

    
    Lorsqu'un processus enfant httpd est créé, le compteur est
    initialisé avec (nombre de microsecondes actuel divisé par 10)
    modulo 65536 (cette formule a été choisie pour éliminer certains
    problème de variance avec les bits de poids faibles du compteur de
    microsecondes sur certains systèmes). Lorsqu'un identifiant unique
    est généré, le repère de temps utilisé est le moment où la requête
    arrive sur le serveur web. Le compteur est incrémenté à chaque
    création d'identifiant (et peut repasser à 0 lorsqu'il a atteint sa
    valeur maximale).
    

    
    Le noyau génère un pid pour chaque processus lors de sa création,
    et le compteur de pid est réinitialisé à une certaine valeur
    lorsqu'il a atteint sa valeur maximale (les pid sont codés sur 16
    bits sous de nombreux Unixes, mais les systèmes les plus récents les
    ont étendus à 32 bits). La même valeur de pid pourra donc être
    réutilisée au cours du temps. Cependant, tant qu'elle n'est pas
    réutilisée dans la même seconde, elle ne remet pas en cause
    l'unicité de notre quadruplet. Nous supposerons donc que le système
    ne créera pas plus de 65536 processus en une seconde (ce nombre peut
    être de 32768 sous certains Unixes, mais même dans ce cas, on est en
    général loin de cette situation).
    

    
    Il est possible que le temps se répète pour une raison
    quelconque.
    Supposons par exemple que l'horloge système soit retardée et repasse
    par un temps passé (ou bien, comme elle avançait, elle a été remise
    à l'heure, et elle repasse par un temps futur). Dans ce cas, il peut
    être facilement démontré que le couple pid/repère de temps peut être
    réutilisé. Le choix de la formule d'initialisation du compteur a
    été effectué dans l'intention de pallier ce problème. Notez qu'un
    nombre vraiment aléatoire serait souhaitable pour initialiser le
    compteur, mais il n'existe pas de tel nombre directement lisible sur
    la plupart des systèmes (c'est à dire que vous ne pouvez pas
    utiliser rand() car vous devez déclencher le générateur avec une
    valeur unique, et vous ne pouvez pas utiliser le temps à cet effet
    car celui-ci , au moins à la seconde près, s'est répété). Il ne
    s'agit donc pas d'une défense parfaite.
    

    
    Même si elle n'est pas parfaite, quel est le degré d'efficacité
    de cette défense ? Supposons
    qu'une de vos machines serve au plus 500 requêtes par seconde (ce
    qui constitue une limite supérieure très raisonnable au moment où ce
    document est écrit, car les systèmes ne se contentent en général pas
    de débiter des fichiers statiques). Pour y parvenir, un certain nombre
    de processus enfants sera nécessaire, qui dépendra du nombre de
    clients simultanés présents. Mais soyons pessimiste et supposons
    qu'un seul processus enfant soit capable de servir 500 requêtes par
    secondes.
    Il existe 1000 valeurs de démarrage possibles du compteur pour
    lesquelles deux séquences de 500 requêtes puissent se recouvrir. Il
    y a donc 1,5% de chance que le processus enfant répète une valeur de
    compteur si le temps se répète (avec une résolution d'une seconde),
    et l'unicité sera alors remise en cause. C'est cependant un exemple
    très pessimiste, et avec les valeurs du monde réel, il y a bien
    moins de chances que cela ne se produise. Si vous estimez que ceci a
    tout de même quelque chances de se produire sur votre système, vous
    pouvez migrer vers un compteur à 32 bits (en modifiant le code).
    

    
    On pourrait supposer que ceci a plus de chance de se produire
    lors du passage à l'heure d'hiver où l'horloge est "retardée". Cela
    ne constitue cependant pas un problème car les temps pris en compte
    ici sont des temps UTC, qui vont "toujours" de l'avant. Notez que
    les Unixes à base de processeur x86 peuvent nécessiter une
    configuration particulière pour que ceci soit vrai -- il doivent
    être configurés pour assumer que l'horloge système est en UTC et
    compenser de manière appropriée. Mais même dans ce cas, si vous
    utilisez NTP, votre temps UTC sera correct peu après le
    redémarrage.
    

    
    
    La variable d'environnement UNIQUE_ID est construite
    par codage du quadruplet de 144 bits (adresse IP sur 32 bits, pid
    sur 32 bits, repère de temps sur 32 bits, compteur 16 bits et index
    de threads sur 32 bits) en
    utilisant l'alphabet [A-Za-z0-9@-] d'une manière
    similaire à celle du codage MIME base64, et sa valeur se présente
    sous la forme d'une chaîne de 24 caractères. L'alphabet MIME base64
    est en fait [A-Za-z0-9+/] ; cependant, les caractères
    + et / nécessitent un codage particulier
    dans les URLs, ce qui rend leur utilisation peu commode. Toutes les
    valeurs sont codées dans l'ordre des octets d'une adresse réseau de
    façon à ce
    que le codage soit comparable entre des architectures où l'ordre des
    octets est différent. L'ordre réel de codage est : repère de temps,
    adresse IP, pid, compteur. Cet ordre de codage possède un but
    précis, mais il faut souligner que les applications n'ont aucun
    intérêt à entrer dans les détails de ce codage. Les applications
    doivent se contenter de traiter la variable UNIQUE_ID
    comme un symbole opaque, qui peut être comparé avec d'autres
    UNIQUE_IDs en ne testant que leur égalité.
    

    
    L'ordre a été choisi de façon à ce qu'il soit possible de
    modifier le codage dans le futur sans avoir à se préoccuper de
    conflits éventuels avec une base de données de
    UNIQUE_IDs existante. Les nouveaux codages doivent
    conserver le repère de temps comme premier élément, et pour le
    reste, utiliser les même alphabet et longueur en bits. Comme les
    repères de temps constituent essentiellement un séquence croissante,
    il suffit que toutes les machines du cluster arrêtent de traiter
    toute requête dans la même seconde repère, et n'utilisent
    alors plus l'ancien format de codage. Ensuite, elles peuvent
    reprendre le traitement des requêtes en utilisant les nouveaux
    codages.
    

    
    Nous pensons que ceci apporte une solution relativement portable
    au problème. Les
    identifiants générés possèdent une durée de vie pratiquement infinie
    car les identifiants futurs pourront être allongés selon les
    besoins. Pratiquement aucune communication n'est requise entre les
    machines du cluster (seule la synchronisation NTP est requise, ce
    qui représente une charge très faible), et aucune communication
    entre les processus httpd n'est nécessaire (la communication est
    implicite et incluse dans le pid assigné par le noyau). Dans des
    situations très spécifiques, l'identifiant peut être raccourci, mais
    dans ce cas, d'avantage d'informations doivent être admises (par
    exemple, les 32 bits de l'adresse IP sont excessifs pour la plupart
    des sites, mais il n'existe pas de valeur de remplacement portable
    plus courte).

    Description:Affiche une présentation complète de la configuration du
serveur
    

    Statut:Extension
    

    Identificateur de Module:info_module
    

    Fichier Source:mod_info.c
    

    Sommaire
    

    
    Pour activer mod_info, ajoutez les lignes
    suivantes à votre fichier httpd.conf.
    

    
    <Location "/server-info">
    SetHandler server-info
</Location>
    


    
    Il est recommandé d'utiliser mod_authz_host à
    l'intérieur de la section <Location> afin de restreindre l'accès aux
    informations de configuration de votre serveur :
    

    
    <Location "/server-info">
    SetHandler server-info
    Require host example.com
</Location>
    


    
    Une fois cette configuration effectuée, les informations du
    serveur sont disponibles à l'adresse
    http://votre-serveur.com/infos-serveur.
    

    


    top
    

    

    Problèmes liés à la sécurité
    
    
    Une fois mod_info chargé dans le serveur, sa
    fonctionnalité de gestionnaire est disponible dans tous les
    fichiers de configuration, y compris les fichiers de configuration
    des répertoires (par exemple .htaccess). Ceci peut
    avoir des répercutions en matière de sécurité pour votre site.
    

    
    En particulier, l'utilisation de ce module peut conduire à la
    divulgation d'informations sensibles à partir des directives de
    configuration d'autres modules Apache comme des chemins systèmes,
    des couples nom d'utilisateur/mot de passe, des noms de bases de
    données, etc... C'est pourquoi ce module ne doit être utilisé
    que dans un environnement sous contrôle et toujours
    avec les plus grandes précautions.
    

    
    Il est recommandé d'utiliser mod_authz_host pour
    restreindre l'accès aux informations de configuration de votre
    serveur.
    

    
    Contrôle d'accès
    <Location "/server-info">
    SetHandler server-info
    # Autorisation d'accès depuis le serveur lui-même
    Require ip 127.0.0.1

    # Autorisation d'accès depuis une station de travail du réseau
# local
    Require ip 192.168.1.17
</Location>
    

    

    top
    

    

    Filtrage des informations affichées
    
    
    Par défaut, les informations affichées comprennent une liste de
    tous les modules activés, et pour chaque module, une description des
    directives qu'il accepte, les branchements (hooks) qu'il
    implémente, ainsi que les directives concernées dans la
    configuration courante.
    

    
    Il est possible d'afficher d'autres vues de la configuration en
    ajoutant un argument à la requête infos-serveur. Par
    exemple, http://votre-serveur.com/infos-serveur?config
    affichera toutes les directives de configuration.
    

    
    
        
    ?<module-name>
    
            
    Uniquement les informations relatives au module
	    spécifié
    
        
    ?config
    
            
    Uniquement les directives de configuration, non triées
	    par module
    
        
    ?hooks
    
            
    Uniquement la liste des branchements (hooks)
	    auxquels le module est attaché
    
        
    ?list
    
            
    Une simple liste des modules activés
    
        
    ?server
    
            
    Uniquement des informations de base sur le serveur
    
        
    ?providers
    
            
    Liste des fournisseurs disponibles sur votre serveur
    	    
    
    

    top
    

    

    Affichage de la configuration au démarrage
    
    
    Si la directive de configuration define
    -DDUMP_CONFIG est utilisée, mod_info va
    envoyer la configuration préinterprétée vers stdout au
    cours du démarrage du serveur.
    
    
    
    httpd -DDUMP_CONFIG -k start
    
    
    
    
    "Préinterprétée" signifie que
    les directives telles que <IfDefine> et <IfModule> sont évaluées et les variables
    d'environnement remplacées par leurs valeurs. Cela ne représente
    cependant pas la configuration définitive. En particulier, les
    fusions ou écrasementsde définitions en cas de directives multiples ne sont pas
    représentés.
    

    
    Le résultat est équivalent à celui de la requête
    ?config.
    
    

    top
    

    

    Limitations connues
    
    
    mod_info tire ses informations de
    la configuration interprétée, et non du fichier de configuration
    original. La manière dont l'arbre de configuration interprété est
    créé induit quelques limitations :
    
    
      
      
    • Les directives qui sont traitées immédiatement sans être
      enregistrées dans l'arbre de configuration interprété ne sont pas
      prises en compte. Celles-ci comprennent ServerRoot, LoadModule et LoadFile.
      • 
      
    • Les directives qui contrôlent le fichier de configuration
      lui-même, comme Include,
      <IfModule> et
      <IfDefine> ne
      sont pas prises en compte, mais les directives de configuration
      incluses le sont.
      • 
      
    • Les commentaires ne sont pas pris en compte (Ce qui peut être
      considéré comme une fonctionnalité).
      • 
      
    • Les directives de configuration des fichiers
      .htaccess ne sont pas prises en compte (car elles ne
      font pas partie de la configuration permanente du serveur).
      • 
      
    • Les directives de conteneur comme <Directory> sont affichées
      normalement, mais mod_info est incapable de
      déterminer le numéro de ligne de la balise fermante
      </Directory>.
      • 
      
    • Les directives générées par des modules tiers comme
      mod_perl peuvent ne pas être
      prises en compte.
      •

    Description:Filtre de mise en cache HTTP conforme à la RFC 2616
    

    Statut:Extension
    

    Identificateur de Module:cache_module
    

    Fichier Source:mod_cache.c
    

    Sommaire
    

    
    Ce module doit être utilisé avec précautions
    car lorsque la directive CacheQuickHandler est définie à sa
    valeur par défaut on, les directives Allow and Deny sont court-circuitées. Vous
    ne devez donc pas activer la gestion rapide de la mise en cache pour
    un contenu auquel vous souhaitez limiter l'accès en fonction du nom
    d'hôte du client, de l'adresse IP ou d'une variable
    d'environnement.
    

    
    mod_cache implémente un filtre de mise
    en cache de contenu HTTP conforme à la RFC 2616, avec
    support de la mise en cache des réponses dont le contenu a été
    négocié et comportant l'en-tête Vary.
    

    
    La mise en cache conforme à la RFC 2616 fournit un mécanisme
    permettant de vérifier si un contenu expiré ou dépassé est encore à
    jour, et peut apporter un gain de performances significatif si le
    serveur original supporte les requêtes
    conditionnelles en prenant en compte l'en-tête de requête
    HTTP If-None-Match.
    Le contenu n'est ainsi régénéré que lorsqu'il a été modifié, et non
    lorsqu'il a expiré.
    

    
    En tant que filtre, mod_cache peut être placé
    en face d'un contenu issu de tout gestionnaire, y compris
    des fichiers à accès séquentiel (servis depuis un
    disque lent mis en
    cache sur un gros disque), la sortie d'un script
    CGI ou d'un générateur de contenu
    dynamique, ou du contenu mandaté depuis un autre
    serveur.
    

    
    Dans la configuration par défaut, mod_cache
    place le filtre de mise en cache aussi loin que possible dans la
    pile de filtres, utilisant le gestionnaire rapide
    pour court-circuiter tout traitement par requête lors de l'envoi du
    contenu au client. Dans ce mode opératoire,
    mod_cache peut être considéré comme un serveur
    mandataire avec cache fixé en tête du serveur web, alors qu'il
    s'exécute dans ce même serveur web.
    

    
    Lorsque le gestionnaire rapide est désactivé via la directive
    CacheQuickHandler, il
    devient possible d'insérer le filtre CACHE à un
    point de la pile de filtres choisi par l'administrateur. Ceci permet
    de mettre en cache un contenu avant que celui-ci ne soit
    personnalisé par le filtre mod_include, ou
    éventuellement compressé par le filtre mod_deflate.
    

    
    Dans le mode de fonctionnement normal, mod_cache
    peut être contrôlé par les en-têtes Cache-Control
    et Pragma
    envoyés par un client dans une requête, ou par un serveur dans une
    réponse. Dans des circonstances exceptionnelles,
    mod_cache peut cependant être configuré pour
    outrepasser ces en-têtes et forcer un comportement spécifique au
    site, bien qu'un tel comportement sera limité à ce cache seulement,
    et n'affectera pas les opérations des autres caches qui peuvent
    s'insérer entre le client et le serveur, et ce type de configuration
    ne doit donc être utiliser qu'en cas de nécessité absolue.
    

    
    La RFC 2616 permet au cache de renvoyer des données périmées
    pendant que l'entrée périmée correspondante est mise à jour depuis
    le serveur original, et mod_cache supporte cette
    fonctionnalité lorsque la directive CacheLock est configurée en
    conséquence. De telles réponses comportent un en-tête HTTP Warning
    contenant un code de réponse 110. La RFC 2616 permet aussi au cache
    de renvoyer des données périmées lorsque la tentative de mise à jour
    des données périmées renvoie une erreur 500 ou supérieure, et cette
    fonctionnalité est supportée par défaut par
    mod_cache. De telles réponses comportent un en-tête HTTP Warning
    contenant un code de réponse 111.
    

    
    mod_cache requiert les services d'un ou
    plusieurs modules de gestion de stockage. La distribution Apache de base
    inclut les modules de gestion de stockage suivants :
    
    
    
    
    mod_cache_disk
    

    
    implémente un gestionnaire de stockage sur disque. Les en-têtes
    et corps sont stockés séparément sur le disque dans une structure de
    répertoires basée sur le condensé md5 de l'URL mise en cache.
    Plusieurs réponses à contenu négocié peuvent être stockées en même
    temps, mais la mise en cache de contenus partiels n'est pas
    supportée par ce module. L'utilitaire
    htcacheclean permet de lister et de supprimer les
    URLs mises en cache, et de maintenir le cache en deçà de
    certaines limites de taille et de nombre d'inodes.
    
    
    mod_cache_socache
    
    
    Implémente un gestionnaire de stockage basé sur un cache d'objets
    partagés. Les en-têtes et corps sont stockés ensemble sous une seule
    clé basée sur l'URL de la réponse mise en cache. Des réponses à
    contenus multiples négociés peuvent être stockées simultanément, mais
    ce module ne supporte pas la mise en cache de contenus partiels.

    reportez-vous au Guide de la mise en
    cache.

    Eviter une tempête de requête
    
  
    Lorsqu'une entrée du cache est périmée, mod_cache
  soumet une requête conditionnelle au processus d'arrière-plan, qui est
  censé confirmer la validité de l'entrée du cache, ou dans la négative
  envoyer une entrée mise à jour.
    
  
    Un court mais non négligeable laps de temps existe entre le moment
  où l'entrée du cache est périmée, et le moment où elle est mise à
  jour. Sur un serveur fortement chargé, un certain nombre de requêtes
  peut arriver pendant ce laps de temps, et provoquer une
  tempête de requêtes susceptibles de saturer le
  processus d'arrière-plan de manière soudaine et imprédictible.
    
  
    Pour contenir cette tempête, on peut utiliser la directive CacheLock afin de définir un répertoire où
  seront créés à la volée des verrous pour les URLs.  Ces
  verrous sont utilisés comme autant d'indications par les
  autres requêtes, soit pour empêcher une tentative de mise en cache (un autre
  processus est en train de récupérer l'entité), soit pour indiquer qu'une
  entrée périmée est en cours de mise à jour (pendant ce temps, c'est le contenu
  périmé qui sera renvoyé).
  
    
  
    Mise en cache initiale d'une entrée
    
    
    
    Lorsqu'une entité est mise en cache pour la première fois, un
    verrou est créé pour cette entité jusqu'à ce que la réponse ait été
    entièrement mise en cache. Pendant la durée de vie du verrou, le
    cache va empêcher une seconde tentative de mise en cache de la même
    entité. Bien que cela ne suffise pas à contenir la tempête de
    requêtes, toute tentative de mettre en cache la même entité
    plusieurs fois simultanément est stoppée.
    
    
  
  
    Mise à jour d'une entrée périmée
    
    
    
    Lorsqu'une entrée atteint la limite de sa durée de vie, et
    devient par conséquent périmée, un verrou est créé pour cette entité
    jusqu'à ce que la réponse ait été soit confirmée comme encore
    valide, soit remplacée par le processus d'arrière-plan. Pendant la
    durée de vie du verrou, une seconde requête entrante va provoquer le
    renvoi de la donnée périmée, et la tempête de requêtes sera
    contenue.
    
  
  
    Verrous et en-tête Cache-Control: no-cache
    
    
    
    Les verrous ne sont utilisés qu'à titre
    indicatif pour enjoindre le cache à être plus coopératif
    avec les serveurs d'arrière-plan, et il est possible de passer outre
    si nécessaire. Si le client envoie une requête contenant un en-tête
    Cache-Control imposant un nouveau téléchargement de l'entité, tout
    verrou éventuel sera ignoré, la requête du client sera honorée
    immédiatement, et l'entrée du cache mise à jour.
    

    
    Comme mécanisme de sécurité supplémentaire, la durée de vie maximale des
    verrous est configurable. Lorsque cette limite est atteinte, le verrou est
    supprimé et une autre requête peut alors en créer un nouveau. Cette durée de
    vie peut être définie via la directive CacheMaxExpire, et sa valeur par défaut est
    de 5 secondes.
    
    
  
  
    Exemple de configuration
    
    
    
    Activation du verrouillage du cache
    #
# Active le verrouillage du cache
#
<IfModule mod_cache.c>
    CacheLock on
    CacheLockPath "/tmp/mod_cache-lock"
    CacheLockMaxAge 5
</IfModule>
    

    
  

    top
    

    

    Contrôle fin via le filtre CACHE
    
  
    Dans son mode de fonctionnement par défaut, le cache s'exécute sous
  la forme d'un gestionnaire rapide, court-circuitant la majorité des
  traitements du serveur et fournissant ainsi une mise en cache
  possédant les plus hautes performances disponibles.
    

  
    Dans ce mode, le cache s'incruste devant le
  serveur, comme si un mandataire de mise en cache indépendant RFC 2616
  était placé devant ce dernier.
    

  
    Bien que que ce mode offre les meilleures performances, les
  administrateurs peuvent souhaiter, dans certaines circonstances,
  effectuer des traitements sur la requête après que cette dernière ait
  été mise en cache, comme ajouter du contenu personnalisé à la page
  mise en cache, ou appliquer des restrictions d'autorisations au
  contenu. Pour y parvenir, l'administrateur sera alors souvent forcé de
  placer des serveurs mandataires inverses indépendants soit derrière,
  soit devant le serveur de mise en cache.
    

  
    Pour résoudre ce problème, la directive CacheQuickHandler peut être définie à
  off, afin que le serveur traite toutes les phases
  normalement exécutées par une requête non mise en cache, y compris les
  phases d'authentification et d'autorisation.
    

  
    En outre, l'administrateur peut éventuellement spécifier le
  point précis dans la chaîne de filtrage où devra
  intervenir la mise en cache en ajoutant le filtre
  CACHE à la chaîne de filtrage en sortie.
    

  
    Par exemple, pour mettre en cache le contenu avant d'appliquer une
  compression à la réponse, placez le filtre CACHE
  avant le filtre DEFLATE comme dans l'exemple suivant
  :
    

  
    # Mise en cache du contenu avant la compression optionnelle
CacheQuickHandler off
AddOutputFilterByType CACHE;DEFLATE text/plain
    


  
    Une autre possibilité consiste à mettre en cache le contenu avant
  l'ajout de contenu personnalisé via mod_include (ou
  tout autre filtre de traitement de contenu). Dans l'exemple suivant,
  les modèles contenant des balises comprises par
  mod_include sont mis en cache avant d'être
  interprétés :
    

  
    # Mise en cache du contenu avant l'intervention de mod_include et
   # mod_deflate
CacheQuickHandler off
AddOutputFilterByType CACHE;INCLUDES;DEFLATE text/html
    


  
    Vous pouvez insérer le filtre CACHE en tout point
  de la chaîne de filtrage. Dans l'exemple suivant, le contenu est mis
  en cache après avoir été interprété par mod_include,
  mais avant d'être traité par mod_deflate :
    

  
    # Mise en cache du contenu entre les interventions de mod_include et
   # mod_deflate
CacheQuickHandler off
AddOutputFilterByType INCLUDES;CACHE;DEFLATE text/html
    


  
    Avertissement :
    Si pour une raison
  ou pour une autre, le point d'insertion du filtre
  CACHE dans la chaîne de filtrage est modifié, vous
  devez vider votre cache pour être sûr que les données
  servies soient à jour. En effet, mod_cache n'est pas
  en mesure d'effectuer cette opération à votre place.

    Etat du cache et journalisation
    
  
    Lorsque mod_cache a décidé s'il devait ou non
  servir une entité depuis le cache, les raisons précises de cette
  décision sont enregistrées dans l'environnement du sous-processus
  interne à la requête sous la clé cache-status.
  Cette information peut être journalisée via la directive LogFormat comme suit :
    

  
    LogFormat "%{cache-status}e ..."
    


  
    En fonction de la décision prise, l'information est aussi écrite
  dans l'environnement du sous-processus sous une des quatre clés
  suivantes :
    

  
    
    
    cache-hit
    Le contenu a été servi depuis le cache.
    
    
    cache-revalidate
    Le contenu du cache était périmé, a été
    mis à jour avec succès, puis servi depuis le cache.
    
    
    cache-miss
    Le contenu n'était pas dans le cache et a été
    servi directement depuis le serveur demandé.
    
    
    cache-invalidate
    L'entité du cache est devenue invalide
    suite à une requête d'un type autre que GET ou HEAD.
    
  
    

  
    Il est alors possible d'envisager une journalisation conditionnelle
  du traitement des requêtes par rapport au cache comme dans l'exemple
  suivant :
    

  
    CustomLog "cached-requests.log" common env=cache-hit
CustomLog "uncached-requests.log" common env=cache-miss
CustomLog "revalidated-requests.log" common env=cache-revalidate
CustomLog "invalidated-requests.log" common env=cache-invalidate
    


  
    Pour les concepteurs de modules, une accroche (hook) nommée
  cache_status est disponible et permet aux modules de
  répondre aux résultats de la vérification du cache ci-dessus de manière
  personnalisée.

    La directive CacheEnable enjoint
    mod_cache de mettre en cache l'URL précisée par
    chaîne URL, ainsi que les URLs de niveaux inférieurs. Le
    gestionnaire de stockage du cache est spécifié à l'aide de l'argument
    type de cache. La directive CacheEnable
    peut être placée à l'intérieur d'une section <Location> ou <LocationMatch> pour indiquer que le contenu
    considéré peut être mis en cache. Si type de cache a pour valeur
    disk, mod_cache utilisera le gestionnaire de
    stockage sur disque implémenté par
    mod_cache_disk. Pour que mod_cache
    utilise le gestionnaire de stockage basé sur le cache d'objets
    partagés implémenté par mod_cache_socache,
    spécifiez socache comme valeur du paramètre type
    de cache.
    
    
    Si les différentes directives CacheEnable
    spécifient des URLs qui se recoupent (comme dans l'exemple
    ci-dessous), tous les gestionnaires de stockage possibles seront
    lancés, jusqu'au premier d'entre eux qui traitera effectivement la
    requête.
    L'ordre dans lequel les gestionnaires de stockage sont lancés est déterminé
    par l'ordre dans lequel apparaissent les directives
    CacheEnable dans le fichier de configuration. Les
    directives CacheEnable situées à l'intérieur de
    sections <Location> ou
    <LocationMatch> sont
    traitées avant les directives CacheEnable définies au
    niveau global.
    

    
    En fonctionnement du type serveur mandataire direct, chaîne
    URL doit au moins débuter par un protocole pour lequel la mise
    en cache doit être activée.

# Mise en cache des contenus mandatés en direct depuis www.example.org (gestionnaire normal ou rapide)

    Un nom d'hôte commençant par un caractère "*"
    correspondra à tout nom d'hôte se terminant par le suffixe
    considéré. Un nom d'hôte commençant par un caractère
    "." correspondra à tout nom d'hôte contenant le
    composant de nom de domaine qui suit ce caractère.
    

    
    # Correspond à www.example.org et fooexample.org
CacheEnable  disk  "http://*example.org/"
# Correspond à www.example.org, mais pas à fooexample.org
CacheEnable  disk  "http://.example.org/"
    


    
    Depuis la version 2.2.12, on peut définir la variable
    d'environnement no-cache pour une définition plus fine
    des ressources à mettre en cache.

    Par exemple, si la dernière modification du document date de 10

    La directive CacheLockPath permet de
  spécifier le répertoire dans lequel les verrous sont créés. Par
  défaut, c'est le répertoire temporaire du système qui est utilisé. Les
  verrous sont des fichiers vides qui n'existent que pour les URLs
  périmées en cours de mise à jour, et consomment donc bien moins de
  ressources que le traditionnel cache sur disque.

    Compatibilité:Disponible à partir de la version 2.3.3 du serveur HTTP
  Apache
    

    
    
    La directive CacheQuickHandler permet de contrôler
    la phase au cours de laquelle la mise en cache est effectuée.
    

    
    Avec la configuration par défaut, le cache agit au cours de la
    phase du gestionnaire rapide. Cette phase court-circuite la majorité
    des traitements du serveur, et constitue le mode d'opération le plus
    performant pour un serveur typique. Le cache
    s'incruste devant le serveur, et la majorité des
    traitements du serveur est court-circuitée.
    

    
    Lorsque cette directive est définie à off, le cache agit comme un
    gestionnaire normal, et est concerné par toutes les phases de
    traitement d'une requête. Bien que ce mode soit moins performant que
    le mode par défaut, il permet d'utiliser le cache dans les cas où un
    traitement complet de la requête est nécessaire, comme par exemple
    lorsque le contenu est soumis à autorisation.
    

    
    # Exécute le cache comme un gestionnaire normal
CacheQuickHandler off
    


    
    Lorsque le gestionnaire rapide est désactivé, l'administrateur a
    aussi la possibilité de choisir avec précision le point de la chaîne
    de filtrage où la mise en cache sera effectuée, en utilisant le
    filtre CACHE.
    

    
    # Mise en cache du contenu avant l'intervention de mod_include et
     # mod_deflate
CacheQuickHandler off
AddOutputFilterByType CACHE;INCLUDES;DEFLATE text/html
    


    
    Si le filtre CACHE est spécifié plusieurs fois, c'est la dernière
    instance qui sera prise en compte.

    Lorsque la directive CacheStaleOnError est définie à
  on, et si des données non mises à jour sont disponibles dans le cache, ce
  dernier renverra ces données, plutôt qu'une éventuelle réponse 5xx en
  provenance du serveur d'arrière-plan. Alors que l'en-tête Cache-Control envoyé
  par les clients sera respecté, et que les clients recevront donc dans ce cas
  la réponse 5xx brute à leur requête, cette réponse 5xx renvoyée au client
  n'invalidera pas le contenu dans le cache.

    Depuis la version 2.2.4, les réponses qui sont arrivées à
    expiration ne sont pas stockées dans le cache. La directive
    CacheStoreExpired permet de modifier ce
    comportement. Avec CacheStoreExpired On, le
    serveur tente de mettre en cache la ressource si elle est périmée.
    Les requêtes suivantes vont déclencher une requête si-modifié-depuis
    de la part du serveur d'origine, et la réponse sera renvoyée à
    partir du cache si la ressource d'arrière-plan n'a pas été modifiée.

    Normalement, les requêtes ou réponses dont l'en-tête
    Cache-Control: no-store ne sont pas stockées dans le
    cache. La directive CacheStoreNoStore permet
    de modifier ce comportement. Si
    CacheStoreNoStore est définie à On, le
    serveur tente de mettre la ressource en cache même si elle contient
    des en-têtes ayant pour valeur no-store. Les ressources
    nécessitant une autorisation ne sont jamais mises en
    cache.
    

    
    
    CacheStoreNoStore On
    

    

    
    Avertissement :
    
       Selon la RFC 2616, la valeur d'en-tête no-store est censée
       "prévenir la suppression ou la rétention par inadvertance
       d'informations sensibles (par exemple, sur des bandes de
       sauvegarde)". Autrement dit, l'activation de la directive
       CacheStoreNoCache pourrait provoquer le
       stockage d'informations sensibles dans le cache. Vous avez donc
       été prévenus.

    Si CacheStorePrivate est définie à On, le serveur
    tentera de mettre la ressource en cache, même si elle
    contient des en-têtes ayant pour valeur private. Les ressources
    nécessitant une autorisation ne sont jamais mises en

       n'est de ce fait appropriée que dans le cas d'un cache
       'privé'.

    Summary
    

    
    mod_socache_redis is a shared object cache provider
    which provides for creation and access to a cache backed by the
    Redis
    high-performance, distributed memory object caching system.
    
    


    
    This shared object cache provider's "create" method requires a
       comma separated list of memcached host/port specifications. If using
       this provider via another modules configuration (such as
       SSLSessionCache), provide
       the list of servers as the optional "arg" parameter.
    

    
    SSLSessionCache redis:redis.example.com:12345,redis2.example.com:12345
    


    
    Details of other shared object cache providers can be found
    here.

    Mise en cache des données d'authentification
    
    
    Certains utilisateurs qui mettent en oeuvre une authentification
    lourde s'appuyant par exemple sur des requêtes SQL
    (mod_authn_dbd) ont signalé une charge induite
    inacceptable sur leur fournisseur d'authentification. Cela se
    produit typiquement dans le cas où une page HTML contient des
    centaines d'objets (images, scripts, pages de styles, media,
    etc...), et où une requête pour cette page génère des centaines de
    sous-requêtes à effet immédiat pour des contenus supplémentaires
    authentifiés.
    
    
    Pour résoudre ce problème, mod_authn_socache fournit une
    solution qui permet de maintenir un cache des données
    d'authentification.
    

    top
    

    

    Utilisation
    
    
    Le cache d'authentification doit être utilisé lorsque les
    requêtes d'authentification induisent une charge significative sur le
    serveur, le serveur d'arrière-plan ou le réseau. Cette mise en cache
    n'apportera probablement aucune amélioration dans le cas d'une
    authentification à base de fichier (mod_authn_file)
    ou de base de données dbm (mod_authn_dbm) car ces
    méthodes sont de par leur conception rapides et légères (la mise en
    cache peut cependant s'avérer utile dans le cas où le fichier est
    situé sur un montage réseau). Les fournisseurs d'authentification
    basés sur SQL ou LDAP ont plus de chances de tirer parti de cette
    mise en cache, en particulier lorsqu'un problème de performances est
    détecté. mod_authnz_ldap gérant son propre cache,
    seul mod_authn_dbd est concerné par notre sujet.
    
    
    Les principales règles à appliquer pour la mise en cache sont :
    
    
    1. Inclure le fournisseur pour lequel vous voulez effectuer une
    mise en cache dans une directive
    AuthnCacheProvideFor.
      2. 
        
    2. Mettre socache avant le fournisseur pour lequel
	vous voulez effectuer une mise en cache dans votre directive
	AuthBasicProvider
	ou AuthDigestProvider.
      3. 
    
    
    
    Voici un exemple simple permettant d'accélérer
    mod_authn_dbd et utilisant dbm comme moteur de la
    mise en cache :
    
    
        #AuthnCacheSOCache est optionnel. S'il est défini, il l'est pour
    #l'ensemble du serveur
AuthnCacheSOCache dbm
<Directory "/usr/www/myhost/private">
    AuthType Basic
    AuthName "Cached Authentication Example"
    AuthBasicProvider socache dbd
    AuthDBDUserPWQuery "SELECT password FROM authn WHERE user = %s"
    AuthnCacheProvideFor dbd
    Require valid-user
    #Optionnel
    AuthnCacheContext dbd-authn-example
</Directory>
    


    top
    

    

    La mise en cache avec les modules tiers
    
    
    Les développeurs de modules doivent savoir que la mise en cache
    avec mod_authn_socache doit être activée dans leurs modules. La
    fonction de l'API ap_authn_cache_store permet de
    mettre en cache les données d'authentification qu'un fournisseur
    vient de rechercher ou de générer. Vous trouverez des exemples
    d'utilisation à r957072, où trois fournisseurs authn sont activés pour la mise
    en cache.

    Directive AuthnCacheContext
    

    

    Description:Spécifie une chaîne de contexte à utiliser dans la clé du
cache
    

    Syntaxe:AuthnCacheContext directory|server|custom-string
    

    Défaut:AuthnCacheContext directory
    

    Contexte:répertoire
    

    Statut:Base
    

    Module:mod_authn_socache
    

    
    
    Cette directive permet de spécifier une chaîne à utiliser avec le
    nom d'utilisateur fourni (et le domaine d'authentification - realm -
    dans le cas d'une authentification à base de condensés) lors de la
    construction d'une clé de cache. Ceci permet de lever l'ambiguïté
    entre plusieurs noms d'utilisateurs identiques servant différentes
    zones d'authentification sur le serveur.
    
    
    Il y a deux valeurs spéciales pour le paramètre : directory,
    qui utilise le contexte de répertoire de la requête comme chaîne, et
    server, qui utilise le nom du serveur virtuel.
    
    
    La valeur par défaut est directory, qui est aussi la
    définition la plus courante. Ceci est cependant loin d'être optimal,
    car par exemple, $app-base, $app-base/images,
    $app-base/scripts et $app-base/media
    possèderont chacun leur propre clé de cache. Il est préférable
    d'utiliser le fournisseur de mot de passe : par exemple un fichier
    htpasswd ou une table de base de données.
    
    
    Les contextes peuvent être partagés entre différentes zones du
    serveur, où les données d'authentification sont partagées. Ceci est
    cependant susceptible de créer des trous de sécurité de type
    cross-site ou cross-application, et cette directive n'est donc pas
    disponible dans les contextes .htaccess.

    Module:mod_authn_socache
    

    
    
    Normalement, cette directive n'est pas nécessaire : l'activation
    est implicite si la mise en cache de l'authentification a été
    activée en tout autre endroit du fichier httpd.conf. Par
    contre, si cette mise en cache n'a pas été activée, par défaut, elle
    ne sera pas initialisée, et ne sera donc pas disponible dans un
    contexte de fichier .htaccess. Cette directive permet
    d'être sûr que la mise en cache a bien été activée et pourra
    donc être utilisée dans les fichiers .htaccess.

    le(s)quel(s) on veut effectuer une mise en cache. Les données
    d'authentification trouvées par un fournisseur non spécifié dans une
    directive AuthnCacheProvideFor ne seront pas mises en
    cache.
    

    
    Par exemple, pour mettre en cache les données d'authentification
    trouvées par mod_authn_dbd ou par un fournisseur
    personnalisé mon-fournisseur, et ne pas mettre en cache
    celles trouvées par les fournisseurs légers comme file ou dbm :

    Module:mod_authn_socache
    

    Compatibilité:Les arguments optionnels du fournisseur sont disponibles
à partir de la version 2.4.7 du serveur HTTP Apache
    

    
    
    Cette définition s'applique à l'ensemble du serveur et permet de
    sélectionner un fournisseur pour le cache
    d'objets partagés, ainsi que des arguments éventuels pour ce
    fournisseur. Les fournisseurs disponibles sont, entre autres, "dbm",
    "dc", "memcache", ou "shmcb", chacun d'entre eux nécessitant le chargement
    du module approprié. Si elle est
    absente, c'est la valeur par défaut pour votre plate-forme qui sera
    utilisée.

    Surcharges autorisées:AuthConfig
    

    Statut:Base
    

    Module:mod_authn_socache
    

    
    
    La mise en cache des données d'authentification peut constituer
    un trou de sécurité, bien qu'un mise en cache de courte durée ne
    posera probablement pas de problème. En général, il est conseillé de
    conserver les entrées du cache de façon à ce que la charge du serveur
    d'arrière-plan reste normale, mais pas plus longtemps ;
    une durée de vie plus longue peut être paramétrée si les
    changements d'utilisateurs et de mots de passe sont peu fréquents.
    La durée de vie par défaut de 300 secondes (5 minutes) est à la fois
    raisonnable et suffisamment importante pour réduire la charge d'un
    serveur d'arrière-plan comme dbd (requêtes SQL).
    
    
    Cette durée de vie ne doit pas être confondue avec la durée de
    vie de session qui est un tout autre sujet. Cependant, vous devez
    utiliser votre logiciel de gestion de session pour vérifier si les
    données d'authentification mises en cache peuvent allonger
    accidentellement une session, et en tenir compte lorsque vous
    définissez la durée de vie.

    ステータス
    

    
    これは、そのモジュールが Apache
    ウェブサーバにどれくらい密接に組み込まれているかを示します。
    言い換えれば、モジュールを組み込み、その機能を利用するために、
    サーバを再コンパイルする必要があるかもしれないということを示します。
    この属性が取り得る値は以下のものです:
    
    
    
      
    MPM
    

      
    ステータスが "MPM" のモジュールはマルチプロセッシングモジュールです。
      他の種類のモジュールとは違って、Apache は常に MPM を一つだけ
      使用し続けます。この種類のモジュールは基本的なリクエストの扱いと
      ディスパッチを行ないます。
    

      
    Base
    

      
    ステータスが "Base"
      のモジュールは、デフォルトでコンパイルされてわざわざ設定から
      モジュールを削除していない限り、通常は利用可能です。
      
    

      
    Extension
    

      
    ステータスが "Extension" のモジュールは、
      デフォルトではコンパイルされず、サーバにも読み込まれません。
      そのモジュールとその機能を有効にするには、
      サーバをビルドするための設定を変更して、Apache
      を再コンパイルする必要があります。
    
      
    Experimental
    

      
    ステータスが "Experimental" のモジュールは、
      Apache 配布物に同梱されていますが、
      使用する場合は自己責任で行なう必要があります。
      そのモジュールは、ドキュメントも完成に向けて作成中ですし、
      サポートされるているとは限りません。
    
      
    External
    

      
    ステータスが "External" のモジュールは、基本 Apache
      配布に同梱されません ("サードパーティーモジュール")。
      そのため、我々に責任はありませんし、
      そのモジュールのサポートもしていません。

mod_proxy_http - Serveur HTTP Apache Version 2.4

    Serveur HTTP Apache Version 2.4
    

    

    <-
    


    

    Module Apache mod_proxy_http
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Module fournissant le support HTTP à
mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_http_module
    

    Fichier Source:mod_proxy_http.c
    

    Sommaire
    

    
    Pour pouvoir fonctionner, ce module requiert le
    chargement de mod_proxy. Il fournit le support du
    mandatement des requêtes HTTP et HTTPS. mod_proxy_http
    supporte HTTP/0.9, HTTP/1.0 et HTTP/1.1. Il ne fournit
    aucune fonctionnalité de mise en cache. Si vous souhaitez
    mettre en oeuvre un mandataire qui assure aussi les fonctions de
    mise en cache, vous devez utiliser les services du module
    mod_cache.
    

    
    Ainsi, pour pouvoir traiter les requêtes HTTP mandatées,
    mod_proxy, et mod_proxy_http
    doivent être chargés dans le serveur.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large.
    
    
    

    


    top
    

    

    Variables d'environnement
    
    
    Outre les directives de configuration qui contrôlent le
    comportement de mod_proxy, plusieurs variables
    d'environnement permettent de contrôler le fournisseur du
    protocole HTTP. Parmi les variables suivantes, celle qui ne
    nécessitent pas de valeur particulière sont définies quelle que soit
    la valeur qu'on leur affecte.
    
    
    
        
    proxy-sendextracrlf
    
        
    Provoque l'envoi par le mandataire d'une nouvelle ligne
	CR-LF supplémentaire à la fin de la requête.
	Ceci constitue un
	moyen de contournement d'une bogue de certains
	navigateurs.
    
        
    force-proxy-request-1.0
    
        
    Force le mandataire à envoyer des requêtes vers le serveur
	cible selon le protocole HTTP/1.0 et désactive les
	fonctionnalités propres à HTTP/1.1.
    
        
    proxy-nokeepalive
    
        
    Force le mandataire à fermer la connexion avec le serveur
	cible après chaque requête.
    
        
    proxy-chain-auth
    
        
    Si le mandataire requiert une authentification, il va lire
	et exploiter les données d'authentification pour mandataire
	envoyées par le client. Si proxy-chain-auth est
	définie, il va aussi faire suivre ces données vers le
	mandataire suivant dans la chaîne. Ceci peut s'avérer nécessaire
	si une chaîne de mandataires partagent les informations
	d'authentification.
	Avertissement concernant la sécurité :
	Ne définissez cette variable que si vous êtes sûr d'en avoir
	besoin, car elle peut provoquer la divulgation d'informations
	sensibles !
    
        
    proxy-sendcl
    
        
    Avec HTTP/1.0, toutes les requêtes qui possèdent un corps
	(par exemple les requêtes POST) doivent comporter un en-tête
	Content-Length. Cette variable d'environnement force
	le mandataire Apache à envoyer cet en-tête au serveur cible,
	sans tenir compte de ce que lui a envoyé le client. Ceci permet
	d'assurer la compatibilité lorsqu'on mandate un serveur cible
	mettant en oeuvre un protocole de type HTTP/1.0 ou inconnu. Elle
	peut cependant nécessiter la mise en tampon de l'intégralité de
	la requête par le mandataire, ce qui s'avère très inefficace
	pour les requêtes de grande taille.
    
        
    proxy-sendchunks ou proxy-sendchunked
    
        
    Cette variable constitue l'opposé de
	proxy-sendcl. Elle permet la transmission des corps
	de requêtes vers le serveur cible en utilisant un codage de
	transfert fractionné. Ceci permet une transmission des requêtes
	plus efficace, mais nécessite que le serveur cible supporte le
	protocole HTTP/1.1.
    
        
    proxy-interim-response
    
        
    Cette variable peut prendre les valeurs RFC
	(valeur par défaut) ou
	Suppress. Les versions précédentes de httpd
	supprimaient les réponses intermédiaires HTTP (1xx) envoyées par
	le serveur cible. En pratique, si un serveur cible envoie une
	réponse intermédiaire, il se peut qu'il étende lui-même le
	protocole d'une manière dont nous n'avons pas connaissance, ou
	tout simplement non conforme. Le comportement du mandataire est
	donc maintenant configurable : définissez
	proxy-interim-response RFC pour être totalement
	compatible avec le protocole, ou proxy-interim-response
	Suppress pour supprimer les réponses intermédiaires.
    
        
    proxy-initial-not-pooled
    
        
    Si cette variable est définie, aucune connexion faisant
	partie d'un jeu ne sera réutilisée si la requête
	du client est la requête initiale pour une connexion.
	Ceci permet d'éviter le message d'erreur
	"proxy: error reading status line from remote server" causé par
	la situation de compétition au cours de laquelle le serveur
	cible ferme la connexion du jeu après la vérification de la
	connexion par le mandataire,  et avant que les données envoyées
	par le mandataire n'atteignent le serveur cible. Il faut
	cependant garder à l'esprit que la définition de cette variable
	dégrade les performances, particulièrement avec les clients
	HTTP/1.0.
        
    
    
    

    top
    

    

    Informations sur les requêtes
    
    
    mod_proxy_http enregistre les informations
    suivantes pour journalisation via le format %{NOMVAR}n
    dans les directives LogFormat ou ErrorLogFormat :
    
    
    
    
        
    proxy-source-port
    
        
    Le port local utilisé pour la connexion vers le serveur
	d'arrière-plan.
    
        
    proxy-status
    
        
    Le code d'état HTTP reçu du serveur d'arrière-plan.

    Serveur HTTP Apache Version 2.4

    Module Apache mod_authn_file
    

    

    Langues Disponibles:  en  |

 ja  |
 ko 
    

    

    Description:Authentification utilisateur à l'aide de fichiers
texte
    

    Statut:Base
    

    Identificateur de Module:authn_file_module
    

    Fichier Source:mod_authn_file.c
    

    Compatibilité:Disponible depuis les versions 2.1 et supérieures
d'Apache
    

    Sommaire
    

    
    Ce module permet aux frontaux d'authentification comme
    mod_auth_digest et mod_auth_basic
    d'authentifier les utilisateurs en les recherchant dans des fichiers
    de mots de passe au format texte. mod_authn_dbm
    fournit une fonctionnalité similaire.
    

    
    Lorsqu'on utilise mod_auth_basic ou
    mod_auth_digest, ce module peut être invoqué en
    affectant la valeur file à la directive AuthBasicProvider ou AuthDigestProvider.

    Directive AuthUserFile
    

    

    Description:Définit le nom d'un fichier texte pour l'authentification
contenant la liste des utilisateurs et de leurs mots de
passe
    

    Syntaxe:AuthUserFile chemin-fichier
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Base
    

    Module:mod_authn_file
    

    
    
    La directive AuthUserFile permet de
    définir le nom d'un fichier texte pour l'authentification contenant
    la liste des utilisateurs et de leurs mots de passe.
    chemin-fichier est le chemin vers le fichier
    des utilisateurs. S'il n'est pas absolu, il est considéré comme
    relatif au répertoire défini par la directive ServerRoot.
    

    
    Chaque ligne du fichier des utilisateurs se compose du nom de
    l'utilisateur, du caractère ':' et du mot de passe chiffré. Si le
    même identifiant utilisateur est référencé plusieurs fois,
    mod_authn_file utilisera la première occurrence pour
    vérifier le mot de passe.
    

     
    Le format du mot de passe chiffré dépend du frontal
     d'authentification utilisé (par exemple
     mod_auth_basic ou
     mod_auth_digest). Voir la documentation sur les
     Formats de mots de
     passe pour plus de détails.
    

    
    Pour mod_auth_basic, utilisez le programme
    htpasswd fourni avec la distribution binaire,
    mais que vous trouverez aussi dans le répertoire
    src/support de l'arborescence des sources. Voir sa page de manuel pour plus de
    détails. En bref :
    

    
    On crée un fichier de mots de passe nom-fichier avec
    nom-utilisateur comme identifiant initial. Le mot de
    passe correspondant sera alors demandé :
    

    
    
      htpasswd -c nom-fichier nom-utilisateur
    
    

    
    Pour ajouter ou modifier nom-utilisateur2 dans le
    fichier de mots de passe nom-fichier :
    

    
    
      htpasswd nom-fichier nom-utilisateur2
    
    

    
    Noter qu'une recherche dans de grands fichiers texte peut être
    très longue ; dans ce cas, il vaut mieux utiliser les fichiers DBM
    avec la directive AuthDBMUserFile.
    

    
    Pour mod_auth_digest, vous devez utiliser
    le programme htdigest.
    Notez que vous ne pouvez pas mélanger des données utilisateur pour
    l'Authentification HTTP à base de condensé et des données pour
    l'Authentification de Base dans le même fichier.
    

    
    Sécurité
    
      
    Assurez-vous que le fichier AuthUserFile
      soit bien stocké en dehors de l'arborescence des documents du
      serveur web. Ne placez pas ce fichier dans le
      répertoire qu'il protège. Dans le cas contraire, les clients
      seraient en mesure de télécharger le fichier des mots de passe.

    Apache Module mod_expires
    

    

    Available Languages:  en  |

    Description:Generation of Expires and
Cache-Control HTTP headers according to user-specified
criteria
    

    Status:Extension
    

    Module Identifier:expires_module
    

    Source File:mod_expires.c
    

    Summary
    

    
    This module controls the setting of the Expires
    HTTP header and the max-age directive of the
    Cache-Control HTTP header in server responses. The
    expiration date can set to be relative to either the time the
    source file was last modified, or to the time of the client
    access.
    

    
    These HTTP headers are an instruction to the client about the
    document's validity and persistence. If cached, the document may
    be fetched from the cache rather than from the source until this
    time has passed. After that, the cache copy is considered
    "expired" and invalid, and a new copy must be obtained from the
    source.
    

    
    To modify Cache-Control directives other than
    max-age (see RFC
    2616 section 14.9), you can use the Header directive.
    

    
     When the Expires header is already part of the response
    generated by the server, for example when generated by a CGI script or
    proxied from an origin server, this module does not change or add
    an Expires or Cache-Control header.

    Alternate Interval Syntax
    
    
    The ExpiresDefault and
    ExpiresByType directives
    can also be defined in a more readable syntax of the form:
    

    
    ExpiresDefault "base  [plus num type] [num type] ..."
ExpiresByType type/encoding "base  [plus num type] [num type] ..."
    


    
    where base is one of:
    

    
      
      
    • access
      • 

      
    • now (equivalent to
      'access')
      • 

      
    • modification
      • 
    
    

    
    The plus keyword is optional. num
    should be an integer value [acceptable to atoi()],
    and type is one of:
    

    
      
      
    • years
      • 
      
    • months
      • 
      
    • weeks
      • 
      
    • days
      • 
      
    • hours
      • 
      
    • minutes
      • 
      
    • seconds
      • 
    
    

    
    For example, any of the following directives can be used to
    make documents expire 1 month after being accessed, by
    default:
    

    
    ExpiresDefault "access plus 1 month"
ExpiresDefault "access plus 4 weeks"
ExpiresDefault "access plus 30 days"
    


    
    The expiry time can be fine-tuned by adding several
    'num type' clauses:
    

    
    ExpiresByType text/html "access plus 1 month 15 days 2 hours"
ExpiresByType image/gif "modification plus 5 hours 3 minutes"
    


    
    Note that if you use a modification date based setting, the
    Expires header will not be added to content
    that does not come from a file on disk. This is due to the fact
    that there is no modification time for such content.

    ExpiresActive Directive
    

    

    Description:Enables generation of Expires
headers
    

    Syntax:ExpiresActive On|Off
    

    Default:ExpiresActive Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Extension
    

    Module:mod_expires
    

    
    
    This directive enables or disables the generation of the
    Expires and Cache-Control headers for
    the document realm in question.  (That is, if found in an
    .htaccess file, for instance, it applies only to
    documents generated from that directory.) If set to
    Off, the headers will not be generated for any
    document in the realm (unless overridden at a lower level, such as
    an .htaccess file overriding a server config
    file). If set to On, the headers will be added to
    served documents according to the criteria defined by the
    ExpiresByType and
    ExpiresDefault
    directives (q.v.).
    

    
    Note that this directive does not guarantee that an
    Expires or Cache-Control header will be
    generated. If the criteria aren't met, no header will be sent, and
    the effect will be as though this directive wasn't even
    specified.
    
 

    

    top
    

    ExpiresByType Directive
    

    

    Description:Value of the Expires header configured
by MIME type
    

    Syntax:ExpiresByType MIME-type
<code>seconds
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Extension
    

    Module:mod_expires
    

    
    
    This directive defines the value of the Expires
    header and the max-age directive of the
    Cache-Control header generated for documents of the
    specified type (e.g., text/html). The second
    argument sets the number of seconds that will be added to a base
    time to construct the expiration date.  The Cache-Control:
    max-age is calculated by subtracting the request time from
    the expiration date and expressing the result in seconds.
    

    
    The base time is either the last modification time of the
    file, or the time of the client's access to the document. Which
    should be used is specified by the
    <code> field; M
    means that the file's last modification time should be used as
    the base time, and A means the client's access
    time should be used.
    

    
    The difference in effect is subtle. If M is used,
    all current copies of the document in all caches will expire at
    the same time, which can be good for something like a weekly
    notice that's always found at the same URL. If A is
    used, the date of expiration is different for each client; this
    can be good for image files that don't change very often,
    particularly for a set of related documents that all refer to
    the same images (i.e., the images will be accessed
    repeatedly within a relatively short timespan).
    

    
    Example:
    # enable expirations
ExpiresActive On
# expire GIF images after a month in the client's cache
ExpiresByType image/gif A2592000
# HTML documents are good for a week from the
# time they were changed
ExpiresByType text/html M604800
    

    

    
    Note that this directive only has effect if
    ExpiresActive On has been specified. It overrides,
    for the specified MIME type only, any expiration date
    set by the ExpiresDefault
    directive.
    

    
    You can also specify the expiration time calculation using
    an alternate syntax, described earlier in
    this document.
    


    

    top
    

    ExpiresDefault Directive
    

    

    Description:Default algorithm for calculating expiration time
    

    Syntax:ExpiresDefault <code>seconds
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Extension
    

    Module:mod_expires
    

    
    
    This directive sets the default algorithm for calculating the
    expiration time for all documents in the affected realm. It can be
    overridden on a type-by-type basis by the ExpiresByType directive. See the
    description of that directive for details about the syntax of the
    argument, and the alternate syntax
    description as well.

    Zusammenfassung
    

    
    Dieses Multi-Processing-Modul (MPM) implementiert einen
    im Voraus forkenden Webserver ohne Thread-Unterstützung, der Anfragen
    auf ähnliche Weise behandelt wie der Apache 1.3. Es ist für
    Angebote geeignet, die aus Kompatibilitätsgründen mit
    nicht-Thread-sicheren Bibliotheken Threading vermeiden müssen.
    Es ist außerdem das geeignetste MPM, um jede Anfrage isoliert
    zu bearbeiten, so dass Probleme mit einem einzelnen Prozess keinen
    anderen beeinflussen.
    

    
    Das MPM ist stark selbstregulierend, so dass es selten
    notwendig ist, seine Konfigurationseinstellungen zu justieren. Das
    Wichtigste ist, dass MaxClients
    gross genug ist, so viele gleichzeitige Anfragen zu bedienen, wie Sie
    erwarten, aber klein genug, um sicherzustellen, dass genug physischer
    Arbeitsspeicher für alle Prozesse vorhanden ist.

    Arbeitsweise
    
    
    Ein einzelner Steuerprozess ist für den Start von
    Kindprozessen verantwortlich, die auf Verbindungen warten und diese
    bedienen, sobald sie eintreffen. Der Apache versucht immer, mehrere
    freie oder unbeschäftigte Serverprozesse vorzuhalten,
    die zur Bedienung eingehender Anfragen bereit stehen. Auf diese Weise
    müssen Clients nicht darauf warten, dass neue Kindprozesse
    geforkt werden, bevor ihre Anfrage bearbeitet werden kann.
    

    
    StartServers,
    MinSpareServers,
    MaxSpareServers und
    MaxClients regulieren,
    wie der Elternprozess Kindprozesse zur Bedienung von Anfragen erstellt.
    Im Allgemeinen ist der Apache sehr selbstregulierend, so dass die meisten
    Angebote die Voreinstellung dieser Direktiven nicht verändern
    müssen. Systeme, die mehr als 256 gleichzeitige Anfragen bedienen
    müssen, können MaxClients erhöhen, während
    Systeme mit begrenztem Arbeitsspeicher möglicherweise
    MaxClients heruntersetzen
    müssen, um den Server vor Flatterverhalten (Arbeitsspeicherinhalte auf
    Platte auslagern - und zurück) zu schützen. Weitere
    Informationen zur Feinabstimmung der Prozesserstellung sind in den
    Performance-Hinweisen zu
    finden.
    

    
    Währen der Elternprozess unter Unix normalerweise als
    root gestartet wird, um sich an Port 80 binden zu können,
    werden die Kindprozesse unter einem weniger privilegierten Benutzer
    gestartet. Die Direktiven User
    und Group werden dazu
    verwendet, die Privilegien der Apache-Kindprozesse festzulegen. Die
    Kindprozesse müssen in der Lage sein, alle Inhalte zu lesen, die
    sie ausliefern sollen, sollten darüber hinaus jedoch so wenig wie
    möglich Rechte besitzen.

    MaxSpareServers-Direktive
    

    

    Beschreibung:Maximale Anzahl der unbeschäftigten Kindprozesse des
  Servers
    

    Syntax:MaxSpareServers Anzahl
    

    Voreinstellung:MaxSpareServers 10
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:prefork
    

    
    
    Die Direktive MaxSpareServers bestimmt das
    gewünschte Maximum an unbeschäftigten
    Kindprozessen des Servers. Ein unbeschäftiger Prozess ist einer, der
    keine Anfrage bedient. Wenn mehr als MaxSpareServers
    Prozesse unbeschäftigt sind, wird der Elternprozess die
    überschüssigen Prozesse beenden.
    

    
    Eine Feineinstellung dieses Parameters sollte nur bei sehr
    beschäftigten Angeboten notwendig sein. Es ist nahezu immer eine
    schlechte Idee, den Parameter auf einen hohen Wert zu setzen. Wenn Sie
    versuchen, den Wert kleiner oder gleich MinSpareServers zu setzen, wird der Apache
    ihn automatisch auf MinSpareServers + 1
    korrigieren.

    Description:A collection of directives that are implemented by
more than one multi-processing module (MPM)
    

    Status:MPM

    CoreDumpDirectory Directive
    

    

    Description:Directory where Apache HTTP Server attempts to
switch before dumping core
    

    Syntax:CoreDumpDirectory directory
    

    Default:See usage for the default setting
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork
    

    
    
    This controls the directory to which Apache httpd attempts to
    switch before dumping core. If your operating system is configured to
    create core files in the working directory of the crashing process,
    CoreDumpDirectory is necessary to change working
    directory from the default ServerRoot
    directory, which should not be writable by the user the server runs as.
    

    
    If you want a core dump for debugging, you can use this directive to
    place it in a different location. This directive has no effect if your
    operating system is not configured to write core files to the working directory
    of the crashing processes.
    

    
    
      
    Security note for Linux systems
    

      
    Using this directive on Linux may allow other processes on
      the system (if running with similar privileges, such as CGI
      scripts) to attach to httpd children via the ptrace
      system call.  This may make weaken the protection from certain
      security attacks.  It is not recommended to use this directive
      on production systems.
    
    
    
    
    
    Core Dumps on Linux
    
      
    If Apache httpd starts as root and switches to another user, the
      Linux kernel disables core dumps even if the directory is
      writable for the process. Apache httpd (2.0.46 and later) reenables core dumps
      on Linux 2.4 and beyond, but only if you explicitly configure a CoreDumpDirectory.
    
    
    

    
    
    
    Core Dumps on BSD
    
    
    To enable core-dumping of suid-executables on BSD-systems (such
    as FreeBSD), set kern.sugid_coredump to 1.
    
    
    
    

    
    Specific signals
    
      
    CoreDumpDirectory processing only occurs for
      a select set of fatal signals: SIGFPE, SIGILL, SIGABORT,
      SIGSEGV, and SIGBUS.
    
      
    On some operating systems, SIGQUIT also results in a core dump but
      does not go through CoreDumpDirectory or
      EnableExceptionHook processing, so the core
      location is dictated entirely by the operating system.

    EnableExceptionHook Directive
    

    

    Description:Enables a hook that runs exception handlers
after a crash
    

    Syntax:EnableExceptionHook On|Off
    

    Default:EnableExceptionHook Off
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork
    

    
    
    For safety reasons this directive is only available if the server was
    configured with the --enable-exception-hook option. It
    enables a hook that allows external modules to plug in and do something
    after a child crashed.
    

    
    There are already two modules, mod_whatkilledus and
    mod_backtrace that make use of this hook. Please have a
    look at Jeff Trawick's EnableExceptionHook site for more information about these.

    GracefulShutdownTimeout Directive
    

    

    Description:Specify a timeout after which a gracefully shutdown server
will exit.
    

    Syntax:GracefulShutdownTimeout seconds
    

    Default:GracefulShutdownTimeout 0
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork
    

    Compatibility:Available in version 2.2 and later
    

    
    
    The GracefulShutdownTimeout specifies
    how many seconds after receiving a "graceful-stop" signal, a
    server should continue to run, handling the existing connections.
    

    
    Setting this value to zero means that the server will wait
    indefinitely until all remaining requests have been fully served.
    


    

    top
    

    Listen Directive
    

    

    Description:IP addresses and ports that the server
listens to
    

    Syntax:Listen [IP-address:]portnumber [protocol]
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    Compatibility:The protocol argument was added in 2.1.5
    

    
    
    The Listen directive instructs Apache httpd to
    listen to only specific IP addresses or ports; by default it
    responds to requests on all IP interfaces. Listen
    is now a required directive. If it is not in the config file, the
    server will fail to start. This is a change from previous versions
    of Apache httpd.
    

    
    The Listen directive tells the server to
    accept incoming requests on the specified port or address-and-port
    combination. If only a port number is specified, the server listens to
    the given port on all interfaces. If an IP address is given as well
    as a port, the server will listen on the given port and
    interface.
    

    
    Multiple Listen directives may be used to
    specify a number of addresses and ports to listen to. The server will
    respond to requests from any of the listed addresses and ports.
    

    
    For example, to make the server accept connections on both
    port 80 and port 8000, use:
    

    
    Listen 80
Listen 8000
    


    
    To make the server accept connections on two specified
    interfaces and port numbers, use 
    

    
    Listen 192.170.2.1:80
Listen 192.170.2.5:8000
    


    
    IPv6 addresses must be surrounded in square brackets, as in the
    following example:
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    


    
    The optional protocol argument is not required for most
       configurations. If not specified, https is the default for
       port 443 and http the default for all other ports.  The
       protocol is used to determine which module should handle a request, and
       to apply protocol specific optimizations with the
       AcceptFilter directive.
    

    
    You only need to set the protocol if you are running on non-standard
       ports.  For example, running an https site on port 8443:
    

    
    Listen 192.170.2.1:8443 https
    


    
    Error condition
    
      Multiple Listen directives for the same ip
      address and port will result in an Address already in use
      error message.

    ListenBackLog Directive
    

    

    Description:Maximum length of the queue of pending connections
    

    Syntax:ListenBackLog backlog
    

    Default:ListenBackLog 511
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    
    
    The maximum length of the queue of pending connections.
    Generally no tuning is needed or desired; however on some
    systems, it is desirable to increase this when under a TCP SYN
    flood attack. See the backlog parameter to the
    listen(2) system call.
    

    
    This will often be limited to a smaller number by the
    operating system. This varies from OS to OS. Also note that
    many OSes do not use exactly what is specified as the backlog,
    but use a number based on (but normally larger than) what is
    set.
    


    

    top
    

    ListenCoresBucketsRatio Directive
    

    

    Description:Ratio between the number of CPU cores (online) and the number of
listeners' buckets
    

    Syntax:ListenCoresBucketsRatio ratio
    

    Default:ListenCoresBucketsRatio 0 (disabled)
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork
    

    Compatibility:Available in Apache HTTP Server 2.4.17, with a kernel supporting
the socket option SO_REUSEPORT and distributing new connections
evenly across listening processes' (or threads') sockets using it (eg. Linux
3.9 and later, but not the current implementations of SO_REUSEPORT
in *BSDs.
    

    
    
    A ratio between the number of (online) CPU cores and the
    number of listeners' buckets can be used to make Apache HTTP Server create
    num_cpu_cores / ratio listening buckets, each containing its
    own Listen-ing socket(s) on the same port(s), and
    then make each child handle a single bucket (with round-robin distribution
    of the buckets at children creation time).
    

    
    Meaning of "online" CPU core
    
    
    On Linux (and also BSD) a CPU core can be turned on/off if 
    Hotplug 
    is configured, therefore ListenCoresBucketsRatio needs to
    take this parameter into account while calculating the number of buckets to create.
    
    
    

    
    ListenCoresBucketsRatio can improve the
    scalability when accepting new connections is/becomes the bottleneck.
    On systems with a large number of CPU cores, enabling this feature has
    been tested to show significant performances improvement and shorter
    responses time.
    

    
    There must be at least twice the number of CPU cores than the
    configured ratio for this to be active. The recommended
    ratio is 8, hence at least 16
    cores should be available at runtime when this value is used.
    The right ratio to obtain maximum performance needs to be calculated
    for each target system, testing multiple values and observing the variations in your 
    key performance metrics.
    

    
    This directive influences the calculation of the 
    MinSpareThreads and 
    MaxSpareThreads lower bound values.
    The number of children processes needs to be a multiple of the number 
    of buckets to optimally accept connections.
    

    
    
    
    Multiple Listeners or Apache HTTP servers on
    the same IP address and port
    
    
    Setting the SO_REUSEPORT option on the listening socket(s)
    consequently allows multiple processes (sharing the same EUID,
    e.g. root) to bind to the the same IP address and port,
    without the binding error raised by the system in the usual case.
    
    
    This also means that multiple instances of Apache httpd configured on a
    same IP:port and with a positive ListenCoresBucketsRatio
    would start without an error too, and then run with incoming connections
    evenly distributed across both instances (this is NOT a recommendation or
    a sensible usage in any case, but just a notice that it would prevent such
    possible issues to be detected).
    
    
    Within the same instance, Apache httpd will check and fail to start if
    multiple Listen directives on the exact same IP (or
    hostname) and port are configured, thus avoiding the creation of some
    duplicated buckets which would be useless and kill performances.  However
    it can't (and won't try harder to) catch all the possible overlapping cases
    (like a hostname resolving to an IP used elsewhere).

    MaxConnectionsPerChild Directive
    

    

    Description:Limit on the number of connections that an individual child server
will handle during its life
    

    Syntax:MaxConnectionsPerChild number
    

    Default:MaxConnectionsPerChild 0
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    Compatibility:Available Apache HTTP Server 2.3.9 and later. The old name
MaxRequestsPerChild is still supported.
    

    
    
    The MaxConnectionsPerChild directive sets
    the limit on the number of connections that an individual child
    server process will handle. After
    MaxConnectionsPerChild connections, the child
    process will die. If MaxConnectionsPerChild is
    0, then the process will never expire.
    

    
    Setting MaxConnectionsPerChild to a
    non-zero value limits the amount of memory that a process can consume
    by (accidental) memory leakage.

    MaxMemFree Directive
    

    

    Description:Maximum amount of memory that the main allocator is allowed
to hold without calling free()
    

    Syntax:MaxMemFree KBytes
    

    Default:MaxMemFree 2048
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware
    

    
    
    The MaxMemFree directive sets the
    maximum number of free Kbytes that every allocator is allowed
    to hold without calling free(). In threaded MPMs, every
    thread has its own allocator. When set
    to zero, the threshold will be set to unlimited.
    


    

    top
    

    MaxRequestWorkers Directive
    

    

    Description:Maximum number of connections that will be processed
simultaneously
    

    Syntax:MaxRequestWorkers number
    

    Default:See usage for details
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork
    

    
    
    The MaxRequestWorkers directive sets the limit
    on the number of simultaneous requests that will be served.  Any
    connection attempts over the MaxRequestWorkers
    limit will normally be queued, up to a number based on the
    ListenBacklog
    directive. Once a child process is freed at the end of a different
    request, the connection will then be serviced.
    

    
    For non-threaded servers (i.e., prefork),
    MaxRequestWorkers translates into the maximum
    number of child processes that will be launched to serve requests.
    The default value is 256; to increase it, you must also raise
    ServerLimit.
    

    
    For threaded and hybrid servers (e.g. event
    or worker), MaxRequestWorkers restricts
    the total number of threads that will be available to serve clients.
    For hybrid MPMs, the default value is 16 (ServerLimit) multiplied by the value of
    25 (ThreadsPerChild). Therefore, to increase MaxRequestWorkers to a value that requires more than 16 processes,
    you must also raise ServerLimit.
    

    
    MaxRequestWorkers was called
    MaxClients before version 2.3.13. The old name is still
    supported.

    MaxSpareThreads Directive
    

    

    Description:Maximum number of idle threads
    

    Syntax:MaxSpareThreads number
    

    Default:See usage for details
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, mpm_netware, mpmt_os2
    

    
    
    Maximum number of idle threads. Different MPMs deal with this
    directive differently.
    

    
    For worker and event, the default is
    MaxSpareThreads 250. These MPMs deal with idle threads
    on a server-wide basis. If there are too many idle threads in the
    server, then child processes are killed until the number of idle
    threads is less than this number. Additional processes/threads
    might be created if ListenCoresBucketsRatio 
    is enabled.
    

    
    For mpm_netware the default is
    MaxSpareThreads 100. Since this MPM runs a
    single-process, the spare thread count is also server-wide.
    

    
    mpmt_os2 works
    similar to mpm_netware. For
    mpmt_os2 the default value is 10.
    

    
    Restrictions
    
      
    The range of the MaxSpareThreads value
      is restricted. Apache httpd will correct the given value automatically
      according to the following rules:

    MinSpareThreads Directive
    

    

    Description:Minimum number of idle threads available to handle request
spikes
    

    Syntax:MinSpareThreads number
    

    Default:See usage for details
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, mpm_netware, mpmt_os2
    

    
    
    Minimum number of idle threads to handle request spikes.
    Different MPMs deal with this directive differently.
    

    
    worker and event use a default of
    MinSpareThreads 75 and deal with idle threads on a server-wide
    basis. If there aren't enough idle threads in the server, then child
    processes are created until the number of idle threads is greater
    than number. Additional processes/threads
    might be created if ListenCoresBucketsRatio 
    is enabled.
    

    
    mpm_netware uses a default of
    MinSpareThreads 10 and, since it is a single-process
    MPM, tracks this on a server-wide basis.
    

    
    mpmt_os2 works
    similar to mpm_netware.  For
    mpmt_os2 the default value is 5.

    PidFile Directive
    

    

    Description:File where the server records the process ID
of the daemon
    

    Syntax:PidFile filename
    

    Default:PidFile logs/httpd.pid
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpmt_os2
    

    
    
    The PidFile directive sets the file to
    which the server records the process id of the daemon. If the
    filename is not absolute, then it is assumed to be relative to the
    ServerRoot.
    

    
    Example
    PidFile /var/run/apache.pid
    

    

    
    It is often useful to be able to send the server a signal,
    so that it closes and then re-opens its ErrorLog and TransferLog, and
    re-reads its configuration files. This is done by sending a
    SIGHUP (kill -1) signal to the process id listed in the
    PidFile.
    

    
    The PidFile is subject to the same
    warnings about log file placement and security.
    

    
    Note
    
      
    As of Apache HTTP Server 2, we recommended that you only use the apachectl script, or the init script that your OS provides,
      for (re-)starting or stopping the server.

    ReceiveBufferSize Directive
    

    

    Description:TCP receive buffer size
    

    Syntax:ReceiveBufferSize bytes
    

    Default:ReceiveBufferSize 0
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    
    
    The server will set the TCP receive buffer size to the number of
    bytes specified.
    

    
    If set to the value of 0, the server will use the
    OS default.

    ScoreBoardFile Directive
    

    

    Description:Location of the file used to store coordination data for

    Syntax:ScoreBoardFile file-path
    

    Default:ScoreBoardFile logs/apache_runtime_status
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt
    

    
    
    Apache HTTP Server uses a scoreboard to communicate between its parent
    and child processes.  Some architectures require a file to facilitate
    this communication. If the file is left unspecified, Apache httpd first
    attempts to create the scoreboard entirely in memory (using anonymous
    shared memory) and, failing that, will attempt to create the file on
    disk (using file-based shared memory). Specifying this directive causes
    Apache httpd to always create the file on the disk.
    

    
    Example
    ScoreBoardFile /var/run/apache_runtime_status
    

    

    
    File-based shared memory is useful for third-party applications
    that require direct access to the scoreboard.
    

    
    If you use a ScoreBoardFile, then
    you may see improved speed by placing it on a RAM disk. But be
    careful that you heed the same warnings about log file placement
    and security.

    SendBufferSize Directive
    

    

    Description:TCP buffer size
    

    Syntax:SendBufferSize bytes
    

    Default:SendBufferSize 0
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    
    
    Sets the server's TCP send buffer size to the number of bytes
    specified. It is often useful to set this past the OS's standard
    default value on high speed, high latency connections
    (i.e., 100ms or so, such as transcontinental fast pipes).
    

    
    If set to the value of 0, the server will use the
    default value provided by your OS.
    

    
    Further configuration of your operating system may be required to elicit
    better performance on high speed, high latency connections.
    

    
     
     On some operating systems, changes in TCP behavior resulting
    from a larger SendBufferSize may not be seen unless
    EnableSendfile is set to OFF.  This
    interaction applies only to static files.

    ServerLimit Directive
    

    

    Description:Upper limit on configurable number of processes
    

    Syntax:ServerLimit number
    

    Default:See usage for details
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, prefork
    

    
    
    For the prefork MPM, this directive sets the
    maximum configured value for MaxRequestWorkers for the lifetime of the
    Apache httpd process. For the worker and event
     MPMs, this directive in combination with ThreadLimit sets
    the maximum configured value for MaxRequestWorkers for the lifetime of the
    Apache httpd process. For the event MPM, this directive
    also defines how many old server processes may keep running and finish processing
    open connections.
    Any attempts to change this directive during a restart will be ignored, but
    MaxRequestWorkers can be modified
    during a restart.
    

    
    Special care must be taken when using this directive.  If
    ServerLimit is set to a value much higher
    than necessary, extra, unused shared memory will be allocated.  If
    both ServerLimit and MaxRequestWorkers are set to values
    higher than the system can handle, Apache httpd may not start or the
    system may become unstable.
    

    
    With the prefork MPM, use this directive only
    if you need to set MaxRequestWorkers higher than 256 (default).
    Do not set the value of this directive any higher than what you
    might want to set MaxRequestWorkers to.
    

    
    With worker, use this directive only if your
    MaxRequestWorkers
     and ThreadsPerChild
    settings require more than 16 server processes (default). Do not set
    the value of this directive any higher than the number of server
    processes required by what you may want for MaxRequestWorkers  and ThreadsPerChild.
    

    
    With event, increase this directive if the process
    number defined by your MaxRequestWorkers and ThreadsPerChild settings, plus the
    number of gracefully shutting down processes, is more than 16 server
    processes (default).
    

    
    Note
    
      
    There is a hard limit of ServerLimit 20000 compiled
      into the server (for the prefork MPM 200000). This is
      intended to avoid nasty effects caused by typos. To increase it
      even further past this limit, you will need to modify the value of
      MAX_SERVER_LIMIT in the mpm source file and rebuild the server.

    Module:event, worker, prefork, mpmt_os2
    

    
    
    The StartServers directive sets the
    number of child server processes created on startup. As the number
    of processes is dynamically controlled depending on the load, (see
    MinSpareThreads,
    MaxSpareThreads,
    MinSpareServers, MaxSpareServers)
    there is usually little reason to adjust this parameter.
    

    
    The default value differs from MPM to MPM. worker and
    event default to StartServers 3; 
    prefork defaults to 5; mpmt_os2
    defaults to 2.

    Number of threads created on startup. As the
    number of threads is dynamically controlled depending on the
    load, (see
    MinSpareThreads,
    MaxSpareThreads,
    MinSpareServers, MaxSpareServers)
    there is usually little reason to adjust this
    parameter.
    

    
    For mpm_netware the default is
    StartThreads 50 and, since there is only a single
    process, this is the total number of threads created at startup to
    serve requests.

    Context:server config
    

    Status:MPM
    

    Module:event, worker, mpm_winnt
    

    
    
    This directive sets the maximum configured value for ThreadsPerChild for the lifetime
    of the Apache httpd process.  Any attempts to change this directive
    during a restart will be ignored, but ThreadsPerChild can be modified
    during a restart up to the value of this directive.
    

    
    Special care must be taken when using this directive.  If
    ThreadLimit is set to a value much higher
    than ThreadsPerChild,
    extra unused shared memory will be allocated.  If both
    ThreadLimit and ThreadsPerChild are set to values
    higher than the system can handle, Apache httpd may not start or the
    system may become unstable. Do not set the value of this directive
    any higher than your greatest predicted setting of ThreadsPerChild for the
    current run of Apache httpd.
    

    
    The default value for ThreadLimit is
    1920 when used with mpm_winnt and
    64 when used with the others.
    

    
    Note
    
      
    There is a hard limit of ThreadLimit 20000 (or
      ThreadLimit 100000 with event,
      ThreadLimit 15000 with mpm_winnt)
      compiled into the server. This is intended to avoid nasty effects
      caused by typos. To increase it even further past this limit, you
      will need to modify the value of MAX_THREAD_LIMIT in the mpm
      source file and rebuild the server.

    Default:See usage for details
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, mpm_winnt
    

    
    
    This directive sets the number of threads created by each
    child process. The child creates these threads at startup and
    never creates more. If using an MPM like mpm_winnt,
    where there is only one child process, this number should be high
    enough to handle the entire load of the server. If using an MPM
    like worker, where there are multiple child processes,
    the total number of threads should be high enough to handle
    the common load on the server.
    

    
    The default value for ThreadsPerChild is
    64 when used with mpm_winnt and
    25 when used with the others.
    
    
    
    The value of ThreadsPerChild can not exceed the
    value of ThreadLimit. If a
    higher value is configured, it will be automatically reduced at start-up
    and a warning will be logged. The relationship between these 2 directives
    is explained in ThreadLimit.

    ThreadStackSize Directive
    

    

    Description:The size in bytes of the stack used by threads handling
client connections
    

    Syntax:ThreadStackSize size
    

    Default:65536 on NetWare; varies on other operating systems
    

    Context:server config
    

    Status:MPM
    

    Module:event, worker, mpm_winnt, mpm_netware, mpmt_os2
    

    Compatibility:Available in Apache HTTP Server 2.1 and later
    

    
    
    The ThreadStackSize directive sets the
    size of the stack (for autodata) of threads which handle client
    connections and call modules to help process those connections.
    In most cases the operating system default for stack size is
    reasonable, but there are some conditions where it may need to be
    adjusted:
    

    
      
      
    • On platforms with a relatively small default thread stack size
      (e.g., HP-UX), Apache httpd may crash when using some third-party modules
      which use a relatively large amount of autodata storage.  Those
      same modules may have worked fine on other platforms where the
      default thread stack size is larger.  This type of crash is
      resolved by setting ThreadStackSize to a
      value higher than the operating system default.  This type of
      adjustment is necessary only if the provider of the third-party
      module specifies that it is required, or if diagnosis of an Apache httpd
      crash indicates that the thread stack size was too small.
      • 

      
    • On platforms where the default thread stack size is
      significantly larger than necessary for the web server
      configuration, a higher number of threads per child process
      will be achievable if ThreadStackSize is
      set to a value lower than the operating system default.  This type
      of adjustment should only be made in a test environment which allows
      the full set of web server processing to be exercised, as there
      may be infrequent requests which require more stack to process.
      The minimum required stack size strongly depends on the modules
      used, but any change in the web server configuration can invalidate
      the current ThreadStackSize setting.
      • 

      
    • On Linux, this directive can only be used to increase the default
      stack size, as the underlying system call uses the value as a
      minimum stack size.  The (often large) soft limit for
      ulimit -s (8MB if unlimited) is used as the default stack
      size.
      • 
    
    

    
    It is recommended to not reduce ThreadStackSize
    unless a high number of threads per child process is needed. On some
    platforms (including Linux), a setting of 128000 is already too low and
    causes crashes with some common modules.

    Fichier Source:mod_charset_lite.c
    

    Sommaire
    

    
    Le module mod_charset_lite permet au serveur de
    modifier le jeu de caractères des réponses avant de les envoyer aux
    clients. Dans un environnement EBCDIC, Apache traduit toujours les
    contenus au protocole HTTP (par exemples les en-têtes de réponses)
    de la page de code de la locale du processus Apache vers ISO-8859-1,
    mais pas le corps des réponses. Dans tous les environnements, on
    peut utiliser mod_charset_lite pour spécifier que
    les corps des réponses doivent être traduits. Par exemple, si les
    fichiers sont stockés sous forme EBCDIC,
    mod_charset_lite pourra les traduire en ISO-8859-1
    avant de les envoyer au client.
    

    
    Ce module fournit quelques procédés de configuration implémentés
    par Apache version russe, ainsi que son module
    mod_charset associé.

    Problèmes courants
    

    
    Noms de jeux de caractères non valides
    

      
    Les noms des jeux de caractères passés en paramètres aux
      directives  CharsetSourceEnc et
      CharsetDefault
      doivent être reconnus par le mécanisme de traduction utilisé par
      APR sur le système où
      mod_charset_lite est utilisé. Ces noms de jeux de
      caractères ne sont pas standardisés, et sont en général différents
      des valeurs qui leur correspondent dans les en-têtes HTTP.
      Actuellement, APR ne peut utiliser que iconv(3) ; vous pouvez donc
      tester facilement vos noms de jeux de caractères en utilisant le
      programme iconv(1), de la manière suivante :
    

      
    
        iconv -f valeur-charsetsourceenc -t valeur-charsetdefault
      
    
    

    
    Incompatibilité entre le jeu de caractères du
    contenu et les règles de traduction
    

      
    Si les règles de traduction ne peuvent s'appliquer au contenu,
      la traduction peut échouer avec des conséquences diverses, comme
      :
    

      
      
      
    • Le mécanisme de traduction peut renvoyer un mauvais code de
      retour, et la connexion sera interrompue.
      • 

      
    • Le mécanisme de traduction peut insérer silencieusement des
      caractères spéciaux (par exemple des points d'interrogation) dans
      le tampon de sortie lorsqu'il n'est pas en mesure de traduire le
      tampon d'entrée.

    La valeur de l'argument jeu de caractères doit être
    un nom de jeu de caractères valide du point de vue du support des
    jeux de caractères dans APR. En général, cela
    implique qu'elle doit être reconnue par iconv.
    

    
    Exemple
    <Directory "/export/home/trawick/apacheinst/htdocs/convert">
    CharsetSourceEnc  UTF-16BE

    valeurs suivantes :
    

    
    
      
    ImplicitAdd | NoImplicitAdd
    

      
    Le mot-clé ImplicitAdd indique que
      mod_charset_lite doit insérer son filtre de
      manière implicite lorsque la configuration indique que le jeu de
      caractère du contenu doit être traduit. Si la chaîne de filtrage
      est configurée de manière explicite via la directive AddOutputFilter, l'option
      NoImplicitAdd doit être utilisée afin que
      mod_charset_lite n'ajoute pas son propre
      filtre.
    

      
    TranslateAllMimeTypes | NoTranslateAllMimeTypes
    
      
    Normalement, mod_charset_lite n'effectuera
      une traduction qu'en présence d'un petit nombre de types MIME
      parmi tous les types possibles. Lorsque l'option
      TranslateAllMimeTypes est utilisée pour une section
      de configuration donnée, la traduction est effectuée sans se
      préoccuper du type MIME.

    La valeur de l'argument jeu de caractères doit être
    un nom de jeu de caractères valide du point de vue du support des
    jeux de caractères dans APR. En général, cela
    implique qu'elle doit être reconnue par iconv.
    

    
    Exemple
    <Directory "/export/home/trawick/apacheinst/htdocs/convert">
    CharsetSourceEnc  UTF-16BE
    CharsetDefault    ISO-8859-1
</Directory>
    

    

    
    Les noms de jeux de caractères de cet exemple sont reconnus par
    le mécanisme de traduction d'iconv sous Solaris 8.
    

    
    
     Spécifier le même jeu de caractères pour les deux directives
     CharsetSourceEnc
     et CharsetDefault
     désactive la traduction. Le jeu de caractères ne doit pas forcément
     correspondre au jeu de caractères de la réponse, mais il doit être
     valide du point de vue du système.

    ソースファイル:mod_dav_lock.c
    

    互換性:バージョン 2.1 以降
    

    概要
    

    
    このモジュールは mod_dav のどのバックエンド
    からでも使える汎用ロック API を提供します。
    使用には最低限 mod_dav
    を必要としますが、これを利用するバックエンドが存在しないと役に立たないので、
    そのような場合はサーバに読み込むべきではありません。
    mod_dav_lock
    を実際に利用するバックエンドモジュールの例としては subversion
    プロバイダモジュールの mod_dav_svn があります。
    

    
    mod_dav_fs は特化された専用のバージョンを
    使うため、この汎用モジュールは必要ないことに注意して
    ください。
    

    
    mod_dav_lock を機能させるには、
    以下で説明されている DavGenericLockDB を使って
    ロックデータベースの場所を指定するだけです。
    

    
    開発者向けのメモ
    
      
    ロックを提供している関数へのポインタを取得するためには、
      ap_lookup_provider API を、引数 dav-lock,
      generic, 0 を指定して使う必要が
      あります。

    Description:Allows an LDAP directory to be used to store the database
for HTTP Basic authentication.
    

    Status:Extension
    

    Module Identifier:authnz_ldap_module
    

    Source File:mod_authnz_ldap.c
    

    Compatibility:Available in version 2.1 and later
    

    Summary
    

    
    This module allows authentication front-ends such as
    mod_auth_basic to authenticate users through
    an ldap directory.
    

    
    mod_authnz_ldap supports the following features:
    

    
      
      
    • Known to support the OpenLDAP SDK (both 1.x
      and 2.x), 
      Novell LDAP SDK and the iPlanet
      (Netscape) SDK.
      • 

      
    • Complex authorization policies can be implemented by
      representing the policy with LDAP filters.
      • 

      
    • Uses extensive caching of LDAP operations via mod_ldap.
      • 

      
    • Support for LDAP over SSL (requires the Netscape SDK) or
      TLS (requires the OpenLDAP 2.x SDK or Novell LDAP SDK).
      • 
    
    

    
    When using mod_auth_basic, this module is invoked
    via the AuthBasicProvider
    directive with the ldap value.

    General caveats
    

     This module caches authentication and authorization results based
on the configuration of mod_ldap. Changes
made to the backing LDAP server will not be immediately reflected on the
HTTP Server, including but not limited to user lockouts/revocations, 
password changes, or changes to group memberships.  Consult the directives 
in mod_ldap for details of the cache tunables.

    Operation
    

    
    There are two phases in granting access to a user. The first
    phase is authentication, in which the mod_authnz_ldap
    authentication provider verifies that the user's credentials are valid.
    This is also called the search/bind phase. The second phase is
    authorization, in which mod_authnz_ldap determines
    if the authenticated user is allowed access to the resource in
    question. This is also known as the compare
    phase.
    

    
    mod_authnz_ldap registers both an authn_ldap authentication
    provider and an authz_ldap authorization handler.  The authn_ldap
    authentication provider can be enabled through the
    AuthBasicProvider directive
    using the ldap value. The authz_ldap handler extends the
    Require directive's authorization types
    by adding ldap-user, ldap-dn and ldap-group
    values.
    


    The Authentication
    Phase
    

    
    During the authentication phase, mod_authnz_ldap
    searches for an entry in the directory that matches the username
    that the HTTP client passes. If a single unique match is found,
    then mod_authnz_ldap attempts to bind to the
    directory server using the DN of the entry plus the password
    provided by the HTTP client. Because it does a search, then a
    bind, it is often referred to as the search/bind phase. Here are
    the steps taken during the search/bind phase.
    

    
      
      
    1. Generate a search filter by combining the attribute and
      filter provided in the AuthLDAPURL directive with
      the username passed by the HTTP client.
      2. 

      
    2. Search the directory using the generated filter. If the
      search does not return exactly one entry, deny or decline
      access.
      3. 

      
    3. Fetch the distinguished name of the entry retrieved from
      the search and attempt to bind to the LDAP server using that
      DN and the password passed by the HTTP client. If the bind is
      unsuccessful, deny or decline access.
      4. 
    
    

    
    The following directives are used during the search/bind
    phase
    

    
    
      
      
    
        AuthLDAPURL

        Specifies the LDAP server, the
        base DN, the attribute to use in the search, as well as the
        extra search filter to use.
      
    

      
    
        AuthLDAPBindDN

        An optional DN to bind with
        during the search phase.
      
    

      
    
        AuthLDAPBindPassword

        An optional password to bind
        with during the search phase.
      
    
    
    



    The Authorization Phase
    

    
    During the authorization phase, mod_authnz_ldap
    attempts to determine if the user is authorized to access the
    resource.  Many of these checks require
    mod_authnz_ldap to do a compare operation on the
    LDAP server. This is why this phase is often referred to as the
    compare phase. mod_authnz_ldap accepts the
    following Require
    directives to determine if the credentials are acceptable:
    

    
      
      
    • Grant access if there is a Require ldap-user directive, and the
      username in the directive matches the username passed by the
      client.
      • 

      
    • Grant access if there is a Require
      ldap-dn directive, and the DN in the directive matches
      the DN fetched from the LDAP directory.
      • 

      
    • Grant access if there is a Require ldap-group directive, and
      the DN fetched from the LDAP directory (or the username
      passed by the client) occurs in the LDAP group or, potentially, in
      one of its sub-groups.
      • 

      
    • Grant access if there is a 
      Require ldap-attribute
      directive, and the attribute fetched from the LDAP directory
      matches the given value.
      • 

      
    • Grant access if there is a 
      Require ldap-filter
      directive, and the search filter successfully finds a single user
      object that matches the dn of the authenticated user.
      • 

      
    • otherwise, deny or decline access
      • 
    
    

    
    Other Require values may also
    be used which may require loading additional authorization modules.
    

    


    
    mod_authnz_ldap uses the following directives during the
    compare phase:
    

    
    
      
      
    
        AuthLDAPURL 

        The attribute specified in the
        URL is used in compare operations for the Require
        ldap-user operation.
      
    

      
    
        AuthLDAPCompareDNOnServer

        Determines the behavior of the
        Require ldap-dn directive.
      
    

      
    
        AuthLDAPGroupAttribute

        Determines the attribute to
        use for comparisons in the Require ldap-group
        directive.
      
    

      
    
        AuthLDAPGroupAttributeIsDN

        Specifies whether to use the
        user DN or the username when doing comparisons for the
        Require ldap-group directive.
      
    

      
    
        AuthLDAPMaxSubGroupDepth

        Determines the maximum depth of sub-groups that will be evaluated
        during comparisons in the Require ldap-group directive.
      
    

      
    
        AuthLDAPSubGroupAttribute

        Determines the attribute to use when obtaining sub-group members
        of the current group during comparisons in the Require ldap-group
        directive.
      
    

      
    
        AuthLDAPSubGroupClass

        Specifies the LDAP objectClass values used to identify if queried directory
        objects really are group objects (as opposed to user objects) during the
        Require ldap-group directive's sub-group processing.

    The Require Directives
    

    
    Apache's Require
    directives are used during the authorization phase to ensure that
    a user is allowed to access a resource.  mod_authnz_ldap extends the
    authorization types with ldap-user, ldap-dn,
    ldap-group, ldap-attribute and
    ldap-filter.  Other authorization types may also be
    used but may require that additional authorization modules be loaded.
    

    
    Since v2.4.8, expressions are supported
    within the LDAP require directives.
    


    Require ldap-user
    

    
    The Require ldap-user directive specifies what
    usernames can access the resource. Once
    mod_authnz_ldap has retrieved a unique DN from the
    directory, it does an LDAP compare operation using the username
    specified in the Require ldap-user to see if that username
    is part of the just-fetched LDAP entry.  Multiple users can be
    granted access by putting multiple usernames on the line,
    separated with spaces. If a username has a space in it, then it
    must be surrounded with double quotes. Multiple users can also be
    granted access by using multiple Require ldap-user
    directives, with one user per line. For example, with a AuthLDAPURL of
    ldap://ldap/o=Example?cn (i.e., cn is
    used for searches), the following Require directives could be used
    to restrict access:
    

    Require ldap-user "Barbara Jenson"
Require ldap-user "Fred User"
Require ldap-user "Joe Manager"
    


    
    Because of the way that mod_authnz_ldap handles this
    directive, Barbara Jenson could sign on as Barbara
    Jenson, Babs Jenson or any other cn that
    she has in her LDAP entry. Only the single Require
    ldap-user line is needed to support all values of the attribute
    in the user's entry.
    

    
    If the uid attribute was used instead of the
    cn attribute in the URL above, the above three lines
    could be condensed to
    

    Require ldap-user bjenson fuser jmanager
    




    Require ldap-group
    

    
    This directive specifies an LDAP group whose members are
    allowed access. It takes the distinguished name of the LDAP
    group. Note: Do not surround the group name with quotes.
    For example, assume that the following entry existed in
    the LDAP directory:
    

    dn: cn=Administrators, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Barbara Jenson, o=Example
uniqueMember: cn=Fred User, o=Example
    

    
    The following directive would grant access to both Fred and
    Barbara:
    

    Require ldap-group cn=Administrators, o=Example
    


    
    Members can also be found within sub-groups of a specified LDAP group
    if AuthLDAPMaxSubGroupDepth
    is set to a value greater than 0. For example, assume the following entries
    exist in the LDAP directory:
    

    dn: cn=Employees, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Managers, o=Example
uniqueMember: cn=Administrators, o=Example
uniqueMember: cn=Users, o=Example

dn: cn=Managers, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Bob Ellis, o=Example
uniqueMember: cn=Tom Jackson, o=Example

dn: cn=Administrators, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Barbara Jenson, o=Example
uniqueMember: cn=Fred User, o=Example

dn: cn=Users, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Allan Jefferson, o=Example
uniqueMember: cn=Paul Tilley, o=Example
uniqueMember: cn=Temporary Employees, o=Example

dn: cn=Temporary Employees, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Jim Swenson, o=Example
uniqueMember: cn=Elliot Rhodes, o=Example
    

    
    The following directives would allow access for Bob Ellis, Tom Jackson,
    Barbara Jenson, Fred User, Allan Jefferson, and Paul Tilley but would not
    allow access for Jim Swenson, or Elliot Rhodes (since they are at a
    sub-group depth of 2):
    

    Require ldap-group cn=Employees, o=Example
AuthLDAPMaxSubGroupDepth 1
    


    
    Behavior of this directive is modified by the AuthLDAPGroupAttribute, AuthLDAPGroupAttributeIsDN, AuthLDAPMaxSubGroupDepth, AuthLDAPSubGroupAttribute, and AuthLDAPSubGroupClass
    directives.
    



    Require ldap-dn
    

    
    The Require ldap-dn directive allows the administrator
    to grant access based on distinguished names. It specifies a DN
    that must match for access to be granted. If the distinguished
    name that was retrieved from the directory server matches the
    distinguished name in the Require ldap-dn, then
    authorization is granted. Note: do not surround the distinguished
    name with quotes.
    

    
    The following directive would grant access to a specific
    DN:
    

    Require ldap-dn cn=Barbara Jenson, o=Example
    


    
    Behavior of this directive is modified by the AuthLDAPCompareDNOnServer
    directive.
    



    Require ldap-attribute
    

    
    The Require ldap-attribute directive allows the
    administrator to grant access based on attributes of the authenticated
    user in the LDAP directory.  If the attribute in the directory
    matches the value given in the configuration, access is granted.
    

    
    The following directive would grant access to anyone with
    the attribute employeeType = active
    

    
    Require ldap-attribute employeeType="active"
    


    
    Multiple attribute/value pairs can be specified on the same line
    separated by spaces or they can be specified in multiple
    Require ldap-attribute directives. The effect of listing
    multiple attribute/values pairs is an OR operation. Access will be
    granted if any of the listed attribute values match the value of the
    corresponding attribute in the user object. If the value of the
    attribute contains a space, only the value must be within double quotes.
    

    
    The following directive would grant access to anyone with
    the city attribute equal to "San Jose" or status equal to "Active"
    

    
    Require ldap-attribute city="San Jose" status="active"
    





    Require ldap-filter
    

    
    The Require ldap-filter directive allows the
    administrator to grant access based on a complex LDAP search filter.
    If the dn returned by the filter search matches the authenticated user
    dn, access is granted.
    

    
    The following directive would grant access to anyone having a cell phone
    and is in the marketing department
    

    
    Require ldap-filter "&(cell=*)(department=marketing)"
    


    
    The difference between the Require ldap-filter directive and the
    Require ldap-attribute directive is that ldap-filter
    performs a search operation on the LDAP directory using the specified search
    filter rather than a simple attribute comparison. If a simple attribute
    comparison is all that is required, the comparison operation performed by
    ldap-attribute will be faster than the search operation
    used by ldap-filter especially within a large directory.

    Examples
    

    
      
      
    • 
        Grant access to anyone who exists in the LDAP directory,
        using their UID for searches.

      AuthLDAPURL "ldap://ldap1.example.com:389/ou=People, o=Example?uid?sub?(objectClass=*)"
Require valid-user
      

      
      • 

      
    • 
        The next example is the same as above; but with the fields
        that have useful defaults omitted. Also, note the use of a
        redundant LDAP server.

      AuthLDAPURL "ldap://ldap1.example.com ldap2.example.com/ou=People, o=Example"
Require valid-user
      

      
      • 

      
    • 
        The next example is similar to the previous one, but it
        uses the common name instead of the UID. Note that this
        could be problematical if multiple people in the directory
        share the same cn, because a search on cn
        must return exactly one entry. That's why
        this approach is not recommended: it's a better idea to
        choose an attribute that is guaranteed unique in your
        directory, such as uid.

      AuthLDAPURL "ldap://ldap.example.com/ou=People, o=Example?cn"
Require valid-user
      

      
      • 

      
    • 
        Grant access to anybody in the Administrators group. The
        users must authenticate using their UID.

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid
Require ldap-group cn=Administrators, o=Example
      

      
      • 

      
    • 
        Grant access to anybody in the group whose name matches the
        hostname of the virtual host. In this example an
        expression is used to build the filter.

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid
Require ldap-group cn=%{SERVER_NAME}, o=Example
      

      
      • 

      
    • 
        The next example assumes that everyone at Example who
        carries an alphanumeric pager will have an LDAP attribute
        of qpagePagerID. The example will grant access
        only to people (authenticated via their UID) who have
        alphanumeric pagers:

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid??(qpagePagerID=*)
Require valid-user
      

      
      • 

      
    • 
        
      The next example demonstrates the power of using filters
        to accomplish complicated administrative requirements.
        Without filters, it would have been necessary to create a
        new LDAP group and ensure that the group's members remain
        synchronized with the pager users. This becomes trivial
        with filters. The goal is to grant access to anyone who has
        a pager, plus grant access to Joe Manager, who doesn't
        have a pager, but does need to access the same
        resource:
      

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid??(|(qpagePagerID=*)(uid=jmanager))
Require valid-user
      


        
      This last may look confusing at first, so it helps to
        evaluate what the search filter will look like based on who
        connects, as shown below.  If
        Fred User connects as fuser, the filter would look
        like
      

        
      (&(|(qpagePagerID=*)(uid=jmanager))(uid=fuser))
      

        
      The above search will only succeed if fuser has a
        pager. When Joe Manager connects as jmanager, the
        filter looks like
      

        
      (&(|(qpagePagerID=*)(uid=jmanager))(uid=jmanager))
      

        
      The above search will succeed whether jmanager
        has a pager or not.

    Using TLS
    

    
    To use TLS, see the mod_ldap directives LDAPTrustedClientCert, LDAPTrustedGlobalCert and LDAPTrustedMode.
    

    
    An optional second parameter can be added to the
    AuthLDAPURL to override
    the default connection type set by LDAPTrustedMode.
    This will allow the connection established by an ldap:// Url
    to be upgraded to a secure connection on the same port.

    To specify a secure LDAP server, use ldaps:// in the

    directive are placed in environment variables with the prefix "AUTHENTICATE_".
    

    
    when this module performs authorization, ldap attributes specified
    in the AuthLDAPURL
    directive are placed in environment variables with the prefix "AUTHORIZE_".
    

    
    If the attribute field contains the username, common name
    and telephone number of a user, a CGI program will have access to
    this information without the need to make a second independent LDAP
    query to gather this additional information.
    

    
    This has the potential to dramatically simplify the coding and
    configuration required in some web applications.

    Using Active Directory
    

    
    An Active Directory installation may support multiple domains at the
    same time. To distinguish users between domains, an identifier called
    a User Principle Name (UPN) can be added to a user's entry in the
    directory. This UPN usually takes the form of the user's account
    name, followed by the domain components of the particular domain,
    for example somebody@nz.example.com.
    

    
    You may wish to configure the mod_authnz_ldap
    module to authenticate users present in any of the domains making up
    the Active Directory forest. In this way both
    somebody@nz.example.com and someone@au.example.com
    can be authenticated using the same query at the same time.
    

    
    To make this practical, Active Directory supports the concept of
    a Global Catalog. This Global Catalog is a read only copy of selected
    attributes of all the Active Directory servers within the Active
    Directory forest. Querying the Global Catalog allows all the domains
    to be queried in a single query, without the query spanning servers
    over potentially slow links.
    

    
    If enabled, the Global Catalog is an independent directory server
    that runs on port 3268 (3269 for SSL). To search for a user, do a
    subtree search for the attribute userPrincipalName, with
    an empty search root, like so:
    


    AuthLDAPBindDN apache@example.com
AuthLDAPBindPassword password
AuthLDAPURL ldap://10.0.0.1:3268/?userPrincipalName?sub
    


    
    Users will need to enter their User Principal Name as a login, in
    the form somebody@nz.example.com.

    Using Microsoft
    FrontPage with mod_authnz_ldap
    

    
    Normally, FrontPage uses FrontPage-web-specific user/group
    files (i.e., the mod_authn_file and
    mod_authz_groupfile modules) to handle all
    authentication. Unfortunately, it is not possible to just
    change to LDAP authentication by adding the proper directives,
    because it will break the Permissions forms in
    the FrontPage client, which attempt to modify the standard
    text-based authorization files.
    

    
    Once a FrontPage web has been created, adding LDAP
    authentication to it is a matter of adding the following
    directives to every .htaccess file
    that gets created in the web
    

    AuthLDAPURL       "the url"
AuthGroupFile     "mygroupfile"
Require group     "mygroupfile"
    



    How It Works
    

    
    FrontPage restricts access to a web by adding the Require
    valid-user directive to the .htaccess
    files. The Require valid-user directive will succeed for
    any user who is valid as far as LDAP is
    concerned. This means that anybody who has an entry in
    the LDAP directory is considered a valid user, whereas FrontPage
    considers only those people in the local user file to be
    valid. By substituting the ldap-group with group file authorization,
    Apache is allowed to consult the local user file (which is managed by
    FrontPage) - instead of LDAP - when handling authorizing the user.
    

    
    Once directives have been added as specified above,
    FrontPage users will be able to perform all management
    operations from the FrontPage client.
    



    Caveats
    

    
      
      
    • When choosing the LDAP URL, the attribute to use for
      authentication should be something that will also be valid
      for putting into a mod_authn_file user file.
      The user ID is ideal for this.
      • 

      
    • When adding users via FrontPage, FrontPage administrators
      should choose usernames that already exist in the LDAP
      directory (for obvious reasons). Also, the password that the
      administrator enters into the form is ignored, since Apache
      will actually be authenticating against the password in the
      LDAP database, and not against the password in the local user
      file. This could cause confusion for web administrators.
      • 

      
      
    • Apache must be compiled with mod_auth_basic,
      mod_authn_file and
      mod_authz_groupfile in order to
      use FrontPage support. This is because Apache will still use
      the mod_authz_groupfile group file for determine
      the extent of a user's access to the FrontPage web.
      • 

      
    • The directives must be put in the .htaccess
      files. Attempting to put them inside <Location> or <Directory> directives won't work. This
      is because mod_authnz_ldap has to be able to grab
      the AuthGroupFile
      directive that is found in FrontPage .htaccess
      files so that it knows where to look for the valid user list. If
      the mod_authnz_ldap directives aren't in the same
      .htaccess file as the FrontPage directives, then
      the hack won't work, because mod_authnz_ldap will
      never get a chance to process the .htaccess file,
      and won't be able to find the FrontPage-managed user file.

    This directive allows you to override the prefix used for environment
    variables set during LDAP authorization.  If AUTHENTICATE_ is
    specified, consumers of these environment variables see the same information
    whether LDAP has performed authentication, authorization, or both.
    

    
    Note
    
    No authorization variables are set when a user is authorized on the basis of
    Require valid-user.

    Status:Extension
    

    Module:mod_authnz_ldap
    

    
    
    By default, subsequent authentication providers are only queried if a
    user cannot be mapped to a DN, but not if the user can be mapped to a DN and their
    password cannot be verified with an LDAP bind.
    If AuthLDAPBindAuthoritative
    is set to off, other configured authentication modules will have
    a chance to validate the user if the LDAP bind (with the current user's credentials)
    fails for any reason.
    
    
     This allows users present in both LDAP and
    AuthUserFile to authenticate
    when the LDAP server is available but the user's account is locked or password
    is otherwise unusable.

    directive identifies the
    labels of members that may be sub-groups of the current group
    (as opposed to user members). The AuthLDAPSubGroupClass
    directive specifies the LDAP objectClass values used in verifying that
    these potential sub-groups are in fact group objects. Verified sub-groups
    can then be searched for more user or sub-group members. Multiple
    attributes can be used by specifying this directive multiple times.
    If not specified, then mod_authnz_ldap uses the
    groupOfNames and groupOfUniqueNames values.

    AuthLDAPURL Directive
    

    

    Description:URL specifying the LDAP search parameters
    

    Syntax:AuthLDAPURL url [NONE|SSL|TLS|STARTTLS]
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authnz_ldap
    

    
    
    An RFC 2255 URL which specifies the LDAP search parameters
    to use. The syntax of the URL is
    

    ldap://host:port/basedn?attribute?scope?filter
    
    
    If you want to specify more than one LDAP URL that Apache should try in turn, the syntax is:
    

    AuthLDAPURL "ldap://ldap1.example.com ldap2.example.com/dc=..."
    


    Caveat: If you specify multiple servers, you need to enclose the entire URL string in quotes;
otherwise you will get an error: "AuthLDAPURL takes one argument, URL to define LDAP connection.." 
You can of course use search parameters on each of these.
    


    

    ldap
    

        
    For regular ldap, use the
        string ldap. For secure LDAP, use ldaps
        instead. Secure LDAP is only available if Apache was linked
        to an LDAP library with SSL support.
    


    host:port
    

        
    
          
    The name/port of the ldap server (defaults to
          localhost:389 for ldap, and
          localhost:636 for ldaps). To
          specify multiple, redundant LDAP servers, just list all
          servers, separated by spaces. mod_authnz_ldap
          will try connecting to each server in turn, until it makes a
          successful connection. If multiple ldap servers are specified,
          then entire LDAP URL must be encapsulated in double quotes.
    

          
    Once a connection has been made to a server, that
          connection remains active for the life of the
          httpd process, or until the LDAP server goes
          down.
    

          
    If the LDAP server goes down and breaks an existing
          connection, mod_authnz_ldap will attempt to
          re-connect, starting with the primary server, and trying
          each redundant server in turn. Note that this is different
          than a true round-robin search.
    
        
    


    basedn
    

        
    The DN of the branch of the
        directory where all searches should start from. At the very
        least, this must be the top of your directory tree, but
        could also specify a subtree in the directory.
    


    attribute
    

        
    The attribute to search for.
        Although RFC 2255 allows a comma-separated list of
        attributes, only the first attribute will be used, no
        matter how many are provided. If no attributes are
        provided, the default is to use uid. It's a good
        idea to choose an attribute that will be unique across all
        entries in the subtree you will be using.  All attributes
        listed will be put into the environment with an AUTHENTICATE_ prefix
        for use by other modules.
    


    scope
    

        
    The scope of the search. Can be either one or
        sub. Note that a scope of base is
        also supported by RFC 2255, but is not supported by this
        module. If the scope is not provided, or if base scope
        is specified, the default is to use a scope of
        sub.
    


    filter
    

        
    A valid LDAP search filter. If
        not provided, defaults to (objectClass=*), which
        will search for all objects in the tree. Filters are
        limited to approximately 8000 characters (the definition of
        MAX_STRING_LEN in the Apache source code). This
        should be more than sufficient for any application. In 2.4.10 and later,
        the keyword none disables the use of a filter; this is
        required by some primitive LDAP servers.
    

    

    
    When doing searches, the attribute, filter and username passed
    by the HTTP client are combined to create a search filter that
    looks like
    (&(filter)(attribute=username)).
    

    
    For example, consider an URL of
    ldap://ldap.example.com/o=Example?cn?sub?(posixid=*). When
    a client attempts to connect using a username of Babs
    Jenson, the resulting search filter will be
    (&(posixid=*)(cn=Babs Jenson)).
    

    
    An optional parameter can be added to allow the LDAP Url to override
    the connection type.  This parameter can be one of the following:
    


    
    
    NONE
    
        
    Establish an unsecure connection on the default LDAP port. This
        is the same as ldap:// on port 389.
    
    
    SSL
    
        
    Establish a secure connection on the default secure LDAP port.
        This is the same as ldaps://
    
    
    TLS | STARTTLS
    
        
    Establish an upgraded secure connection on the default LDAP port.
        This connection will be initiated on port 389 by default and then
        upgraded to a secure connection on the same port.
    

    

    
    See above for examples of AuthLDAPURL URLs.

    Apache MPM winnt
    

    

    Langues Disponibles:  de  |

    Description:Module multi-processus optimisé pour Windows
NT.
    

    Statut:MPM
    

    Identificateur de Module:mpm_winnt_module
    

    Fichier Source:mpm_winnt.c
    

    Sommaire
    

    
    Ce module multi-processus (MPM) est le module par défaut pour les
    systèmes d'exploitation de style Windows NT. Il consiste en un
    processus de contrôle unique qui lance un processus enfant unique,
    ce dernier créant à son tour des threads pour traiter les
    requêtes.
    

    
    La directive ThreadsPerChild définit le
    nombre maximal de connexions clientes simultanées.
    

    
    Ce MPM utilise par défaut les APIs Windows avancées pour accepter
    les nouvelles connexions des clients. Avec certaines configurations,
    des produits tiers peuvent interférer avec cette implémentation, et
    provoquer l'enregistrement des messages suivants dans les journaux
    du serveur :
    

    
    
        Child: Encountered too many AcceptEx faults accepting client connections.
    
        winnt_mpm: falling back to 'AcceptFilter none'.
    
    

    
    Le MPM se rabat sur une implémentation plus sûre, mais certaines
    requêtes n'ont pas été traitées correctement. Pour éviter cette
    erreur, définissez la directive AcceptFilter à none.
    

    
    AcceptFilter http none
AcceptFilter https none
    


    
    Avec les versions 2.0 et 2.2 d'Apache httpd, c'est la directive
    Win32DisableAcceptEx qui était utilisée à cet
    effet.
    

    
    Le MPM WinNT diffère des autres MPMs Unix comme worker et event
    à bien des égards :
    

    
      
      
    • Lorsqu'un processus enfant s'arrête suite à un arrêt ou
      redémarrage du serveur, ou lorsque que la limite MaxConnectionsPerChild est
      atteinte, les requêtes en cours de traitement par ce processus en
      cours d'arrêt n'ont que TimeOut secondes pour s'exécuter avant
      l'arrêt du processus. Les autres types de redémarrage ou arrêt ne
      sont pas implémentés.
      • 

      
    • Les nouveau processus enfants relisent les fichiers de
      configuration au lieu d'en hériter du parent. Ce comportement ne
      pose pas de problème si le processus enfant est créé au démarrage
      ou redémarrage, mais dans le cas où un processus enfant est créé
      parce qu'un autre processus enfant s'est arrêté ou a atteint la
      limite MaxConnectionsPerChild, tout
      changement survenu entre temps dans la configuration sera alors
      pris en compte dans le processus enfant, et parent et enfant
      utiliseront une configuration différente. Si des modifications
      planifiées de la configuration ont été partiellement effectuées,
      et si la configuration courante n'est pas interprétable, le
      processus enfant de remplacement ne pourra pas démarrer, et le
      serveur s'arrêtera. En conséquence, toute modification des
      fichiers de configuration doit être accompagnée d'un redémarrage
      du serveur.
      • 

      
    • Les hooks monitor et fatal_exception
      ne sont pas encore implémentés.
      • 

      
    • La directive AcceptFilter est
      implémentée par le MPM et fournit un type de contrôle différent
      sur le traitement des nouvelles connexions (Voir la documentation
      de la directive AcceptFilter
      pour plus de détails).

    Module Apache mod_proxy_express
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Extension à mod_proxy pour le mandatement
dynamique inverse de masse
    

    Statut:Extension
    

    Identificateur de Module:proxy_express_module
    

    Fichier Source:mod_proxy_express.c
    

    Compatibilité:Disponible à partir de la version 2.3.13 du serveur HTTP Apache
    

    Sommaire
    

    
    Ce module crée dynamiquement en masse des mandataires inverses en
    faisant correspondre l'en-tête Host: de la requête HTTP à un nom de
    serveur et une URL d'arrière-plan stockés dans un fichier DBM. Il
    est ainsi plus aisé d'utiliser un grand nombre de
    mandataires inverses sans avoir à modifier la configuration. Il est
    loin de posséder autant de fonctionnalités que
    mod_proxy_balancer qui propose aussi la croissance
    dynamique, mais il est conçu pour gérer un nombre beaucoup plus important
    de serveurs d'arrière-plan. Il convient parfaitement pour créer un
    commutateur HTTP frontal et pour les architectures Microservices.
    

    
    Pour pouvoir être utilisé, ce module nécessite le chargement de
    mod_proxy.
    

    
    Avertissement
    
      
    N'activez le mandatement que si vous avez sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux pour votre réseau, et
      dans une plus large mesure pour Internet.
    
    
    


    Limitations
    
  
      
    
    • Ce module n'est pas conçu pour remplacer les fonctionnalités dynamiques
    de mod_proxy_balancer. Par contre, il peut constituer une
    alternative légère et rapide à mod_rewrite lorsque ce
    dernier utilise la directive RewriteMap et le drapeau [P]
    pour le mandatement inverse à partir d'une table de correspondances.
    
      • 
    
    • Il ne supporte pas les mises en correspondance basées sur les
    expressions rationnelles ou les modèles.
    
      • 
    
    • Il émule :
      
      <VirtualHost *:80>
   ServerName front.end.server
   ProxyPass "/" "back.end.server:port"
   ProxyPassReverse "/" "back.end.server:port"
</VirtualHost>
      

      En d'autres termes, l'URL dans son ensemble est ajoutée à l'URL
      d'arrière-plan correspondante, tout ceci dans le but de
      proposer un commutateur mandataire inverse simple mais rapide.

    Module Apache mod_authz_dbd
    

    

    Langues Disponibles:  en  |

    Description:Autorisation en groupe et reconnaissance d'identité avec base
SQL
    

    Statut:Extension
    

    Identificateur de Module:authz_dbd_module
    

    Fichier Source:mod_authz_dbd.c
    

    Compatibilité:Disponible dans les versions 2.4 et supérieures
d'Apache
    

    Sommaire
    

    
    Ce module fournit des fonctionnalités d'autorisation permettant
    d'accorder ou de refuser aux utilisateurs authentifiés l'accès à
    certaines zones du site web en fonction de leur appartenance à tel
    ou tel groupe. Les modules mod_authz_groupfile et
    mod_authz_dbm fournissent une fonctionnalité
    similaire, mais ici le module interroge une base de données SQL pour
    déterminer si un utilisateur appartient ou non à tel ou tel groupe.
    
    
    Ce module propose également des fonctionnalités de connexion
    utilisateur s'appuyant sur une base de données, ce qui peut se révéler
    particulièrement utile lorsque le module est utilisé conjointement avec
    mod_authn_dbd.
    
    
    Ce module s'appuie sur mod_dbd pour spécifier le
    pilote de la base de données sous-jacente et les paramètres de
    connexion, et gérer les connexions à la base de données.
    

    


    top
    

    

    Les directives Require
    

    
    Les directives Require d'Apache permettent,
    au cours de la phase d'autorisation, de s'assurer qu'un utilisateur
    est bien autorisé à accéder à une ressource. mod_authz_dbd ajoute
    les types d'autorisation dbd-group,
    dbd-login et dbd-logout.
    

    
    A partir de la version 2.4.8, les directives require DBD
    supportent les expressions.
    


    Require dbd-group
    

    
    Cette directive permet de spécifier à quel groupe un utilisateur
    doit appartenir pour obtenir l'autorisation d'accès.
    

    
    Require dbd-group team
AuthzDBDQuery "SELECT group FROM authz WHERE user = %s"
    





    Require dbd-login
    

    
    Cette directive permet de spécifier une requête à exécuter pour
    indiquer que l'utilisateur s'est authentifié.
    

    
    Require dbd-login
AuthzDBDQuery "UPDATE authn SET login = 'true' WHERE user = %s"
    





    Require dbd-logout
    

    
    Cette directive permet de spécifier une requête à exécuter pour
    indiquer que l'utilisateur s'est déconnecté.
    

    
    Require dbd-logout
AuthzDBDQuery "UPDATE authn SET login = 'false' WHERE user = %s"
    





    top
    

    

    Reconnaissance d'identité s'appuyant sur une base de données
    


    
Outre sa fonction d'autorisation standard consistant à vérifier
l'appartenance à des groupes, ce module permet aussi de gérer des
sessions utilisateur côté serveur grâce à sa fonctionnalité de connexion utilisateur
en s'appuyant sur une base de données. En particulier, il peut mettre à
jour le statut de session de l'utilisateur dans la base de données
chaque fois que celui-ci visite certaines URLs (sous réserve bien
entendu que l'utilisateur fournissent les informations de connexion
nécessaires).
    

    Pour cela, il faut definir deux directives Require spéciales : Require
dbd-login et Require dbd-logout. Pour les détails de
leur utilisation, voir l'exemple de configuration ci-dessous.
    

    top
    

    

    Reconnaissance d'identité côté client
    


    Certains administrateurs peuvent vouloir implémenter une gestion de
session côté client fonctionnant de concert avec les fonctionnalités de
connexion/déconnexion des utilisateurs côté serveur offertes par ce module, en
définissant ou en annulant par exemple un cookie HTTP ou un jeton
similaire lorsqu'un utilisateur se connecte ou se déconnecte.
    


    Pour supporter une telle intégration, mod_authz_dbd exporte
un programme à déclenchement optionnel (hook) qui sera lancé chaque fois
que le statut d'un utilisateur sera mis à jour dans la base de données.
D'autres modules de gestion de session pourront alors utiliser ce
programme pour implémenter des fonctions permettant d'ouvrir et de
fermer des sessions côté client.

    Module Apache mod_authz_host
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Autorisations de groupe basées sur l'hôte (nom ou adresse
IP)
    

    Statut:Base
    

    Identificateur de Module:authz_host_module
    

    Fichier Source:mod_authz_host.c
    

    Compatibilité:Le fournisseur forward-dns est disponible à partir
de la version 2.4.19 du serveur HTTP Apache
    

    Sommaire
    

    
    Les fournisseurs d'autorisation implémentés par le module
    mod_authz_host sont enregistrés à l'aide de
    la directive Require. On peut
    utiliser cette directive à l'intérieur de sections <Directory>, <Files>, ou <Location> ou de fichiers
    .htaccess  pour
    contrôler l'accès à certaines zones du serveur. Le contrôle d'accès
    peut être effectué en fonction du nom d'hôte ou de l'adresse IP.
    

    
    En général, les directives de restriction d'accès s'appliquent à
    toutes les méthodes d'accès (GET, PUT,
    POST, etc...). C'est d'ailleurs ce que l'on souhaite
    dans la plupart des cas. Il est cependant possible de ne restreindre
    l'accès que pour certaines méthodes, tout en laissant les autres
    méthodes sans protection, en plaçant les directives dans une section
    <Limit>.
    

    


    top
    

    

    Les directives Require
    

    
    La directive Apache Require est utilisée au cours de
    la phase d'autorisation pour vérifier si un utilisateur se voit
    accorder ou refuser l'accès à une ressource. mod_authz_host fournit
    les types d'autorisation ip, host,
    forward-dns et local. D'autres
    types d'autorisation sont aussi disponibles, mais nécessitent le chargement
    des modules d'autorisation appropriés.
    

    
    Ces fournisseurs d'autorisation permettent de déterminer quels
    hôtes peuvent accéder à une zone du serveur. On peut contrôler
    l'accès en fonction du nom d'hôte, de l'adresse IP, ou d'un intervalle
    d'adresses IP.
    

    
    A partir de la version 2.4.8, les directives require host
    supportent les expressions.
    


    Require ip
    

    
    Le fournisseur ip permet de contrôler l'accès au
    serveur en fonction de l'adresse IP du client distant. Lorsque
    Require ip adresse-ip est spécifié, la
    requête est autorisée si l'adresse IP du client distant correspond
    à
    

    
    Une adresse IP complète :
    

    
    Require ip 10.1.2.3
Require ip 192.168.1.104 192.168.1.205
    


    
    L'adresse IP d'un hôte pour qui l'accès est accordé
    

    
    Une adresse IP partielle :
    

    
    Require ip 10.1
Require ip 10 172.20 192.168.2
    

    
    Les 1 à 3 premiers octets d'une adresse IP, pour une restriction
    à un sous-réseau.
    

    
    Une paire réseau/masque de sous-réseau :
    

    
    Require ip 10.1.0.0/255.255.0.0
    

    
    Un réseau a.b.c.d, et un masque de sous-réseau w.x.y.z. pour une
    restriction de sous-réseau plus fine.
    

    
    Une spécification CIDR réseau/nnn :
    

    
    Require ip 10.1.0.0/16
    

    
    Identique au cas précédent, excepté que le masque de sous-réseau
    représente les nnn premiers bits de poids fort.
    

    
    Notez que les trois derniers exemples correspondent exectement au
    même ensemble d'hôtes.
    

    
    On peut spécifier des adresses et des sous-réseaux IPv6 comme
    suit :
    

    
    Require ip 2001:db8::a00:20ff:fea7:ccea
Require ip 2001:db8:1:1::a
Require ip 2001:db8:2:1::/64
Require ip 2001:db8:3::/48
    


    
    Note: comme les adresses IP sont lues au démarrage, les
    expressions ne sont pas évaluées au moment de la requête.
    




    Require host
    

    
    Le fournisseur host permet de contrôler l'accès au
    serveur en fonction du nom d'hôte du client distant. Lorsque
    Require host nom-hôte est spécifié, la
    requête est autorisée si le nom d'hôte correspond à
    

    
    Un nom de domaine (éventuellement partiel)
    

    
    Require host example.org
Require host .net example.edu
    


    
    Les hôtes dont les noms correspondent ou se terminent par la
    chaîne spécifiée se voient accorder l'accès. Seuls les élément de
    nom de domaine complets sont mis en correspondance ; ainsi,
    l'exemple ci-dessus correspondra à foo.example.org, mais
    ne correspondra pas à fooexample.org. Avec cette
    configuration, Apache va effectuer une double recherche DNS sur
    l'adresse IP du client, sans tenir compte de la définition de la
    directive  HostnameLookups. Il
    va effectuer une recherche DNS inverse sur l'adresse IP pour trouver
    le nom d'hôte associé, puis une recherche DNS directe sur le nom
    d'hôte pour vérifier qu'il correspond bien à l'adresse IP originale.
    L'accès ne sera accordé que si le nom d'hôte correspond et si les
    recherches DNS inverse et directe sont cohérentes.
    




    Require forward-dns
    

    
    Le fournisseur forward-dns permet d'accéder au serveur
    sécurisé en fonction de simples noms d'hôte. Lorsque Require
    forward-dns host-name est spécifié, toute adresse IP
    correspondant à host-name se voit autoriser l'accès.
    

    
    A la différence du fournisseur host, ce fournisseur
    n'effectue pas de recherche DNS inverse : il effectue simplement une requête
    DNS directe pour le nom d'hôte spécifié et donne accès au client si son
    adresse IP correspond. Il ne fonctionnera donc qu'avec des noms d'hôte, et
    non avec des noms de domaine. Par contre, comme le DNS inverse n'est pas
    sollicité, il fonctionnera avec des clients qui utilisent un service de DNS
    dynamique.
    

    
    Require forward-dns dynamic.example.org
    


    
    Un client dont l'adresse IP correspond au nom d'hôte
    dynamic.example.org  se verra autoriser l'accès.
    




    Require local
    

    
    Le fournisseur local autorise l'accès au serveur si
    l'une au moins de ces conditions est satisfaite :
    

    
      
        
    • l'adresse IP du client correspond à 127.0.0.0/8
      • 
        
    • l'adresse IP du client est ::1
      • 
        
    • les adresses IP du client et du serveur sont identiques
      • 
    
    

    
    L'exemple suivant montre une méthode simple pour sélectionner les
    connexions en provenance de l'hôte local :
    

    
    Require local
    





    Note concernant la sécurité
    

    
    Si le contenu de votre serveur est mandaté, vous devez garder à
    l'esprit que l'adresse client correspondra à l'adresse de votre
    serveur mandataire et non à l'adresse du client, et l'utilisation de
    la directive Require dans ce contexte ne provoquera pas
    forcément l'effet désiré. Voir mod_remoteip pour
    une solution possible à ce problème.

    Description:Multi-Processing Module optimized for Windows NT.
    

    Status:MPM
    

    Module Identifier:mpm_winnt_module
    

    Source File:mpm_winnt.c
    

    Summary
    

    
    This Multi-Processing Module (MPM) is the default for the
    Windows NT operating systems. It uses a single control process
    which launches a single child process which in turn creates
    threads to handle requests
    

    
    Capacity is configured using the 
    ThreadsPerChild directive,
    which sets the maximum number of concurrent client connections.
    

    
    By default, this MPM uses advanced Windows APIs for accepting
    new client connections.  In some configurations, third-party products
    may interfere with this implementation, with the following messages
    written to the web server log:
    

    
    
        Child: Encountered too many AcceptEx faults accepting client connections.
    
        winnt_mpm: falling back to 'AcceptFilter none'.
    
    

    
    The MPM falls back to a safer implementation, but some client requests
    were not processed correctly.  In order to avoid this error, use
    AcceptFilter with accept filter 
    none.
    

    
    AcceptFilter http none
AcceptFilter https none
    

    
    
    In Apache httpd 2.0 and 2.2,
    Win32DisableAcceptEx was used for this purpose.
    

    
    The WinNT MPM differs from the Unix MPMs such as worker and event
    in several areas:
    

    
      
      
    • When a child process is exiting due to shutdown, restart, or
      MaxConnectionsPerChild,
      active requests in the exiting process have
      TimeOut seconds to finish before
      processing is aborted.  Alternate types of restart and shutdown are not
      implemented.
      • 

      
    • New child processes read the configuration files instead of
      inheriting the configuration from the parent.  The behavior will
      be the same as on Unix if the child process is created at startup
      or restart, but if a child process is created because the prior
      one crashed or reached 
      MaxConnectionsPerChild,
      any pending changes to the configuration will become active in the
      child at that point, and the parent and child will be using a
      different configuration.  If planned configuration changes have been
      partially implemented and the current configuration cannot be
      parsed, the replacement child process cannot start up and the server 
      will halt.  Because of this behavior, configuration files should not
      be changed until the time of a server restart.
      • 

      
    • The monitor and fatal_exception hooks
      are not currently implemented.
      • 

      
    • AcceptFilter is implemented in the MPM
      and has a different type of control over handling of new connections.
      (Refer to the AcceptFilter
      documentation for details.)
      •

    Normal şartlar altında, durağan dosyaların öntanımlı eylemcileri gibi
      istek eylemcileri gerek kalmadığında istek gövdesini iptal ederler. Sonuç
      olarak, mod_include gibi süzgeçler, özgün istek (süzme işlemi
      gerçekleştikten sonra artık gerekmediğinden istek gövdesini iptal eden)
      bir POST isteği olsa bile, GET isteklerinin
      yapılmasına sadece diğer URL’lerin alt istekler olarak içerilmesi
      şartıyla  izin verir.
    

    
    Bu yönergede belirtilen değer sıfırdan büyük olduğunda, istek
      eylemciler, istek gövdesini iptal etmek yerine süzgeçler tarafından
      kullanılmak üzere belirtilen azami boyuta ayarlarlar. mod_include
      süzgecinin kullanılması durumunda, bir durağan shtml dosyası için bir
      POST isteği, ardından gelen isteklerin, önceki gibi
      GET istekleri değil, POST istekleri olmasına
      yol açacaktır.
    

    
    Bu özellik, mod_include kullanılarak, karmaşık HTML
      sayfalarının ve uygulamalarının küçük küçük bileşenlere bölünüp sonra da
      sayfa yapısıyla birlikte sarmalanarak birleştirilmesini mümkün kılar.
      Bileşenler, CGI programları veya betik dilleri biçiminde olabileceği
      gibi, mod_proxy kullanarak başka bir sunucudaki URL
      uzayına ters vekil URL’ler şeklinde bile olabilir.
    

    
    Bilginize: İstekler tamamlanana kadar alınan istekler
      geçici RAM içinde biriktirilir. Sonuç olarak, bahsi geçen yükü karşılamak
      için yeterince RAM’in mevcut olması gerekir. Bu yönergeyi kullanmakla,
      istek gövdesini saklamaya yetecek olası en düşük değerle bile URL
      uzayınız için gereken yeri kısıtlamış olursunuz.
    

    
    Eğer isteğin uzunluğu bu yönerge ile ayrılan azami uzunluğu aşarsa
      sunucu yanıt olarak 413 Request Entity Too Large (413
      İstenen Öğe Çok Büyük) hatasını döndürür.

    Variables d'environnement
    


    Ce module peut être configuré pour fournir aux espaces de nommage SSI
et CGI de nombreux éléments d'informations concernant SSL par le biais
de variables d'environnement supplémentaires. Par défaut, sauf pour
HTTPS et SSL_TLS_SNI qui sont toujours définies, ces
informations ne sont pas fournies pour des raisons de performances (Voir
la directive SSLOptions
StdEnvVars ci-dessous).
Les variables générées se trouvent dans la table ci-dessous.
Ces informations peuvent également être disponible sous des noms différents
à des fins de compatibilité ascendante. Reportez-vous au chapitre Compatibilité pour plus de détails à
propos des variables de compatibilité.

    x509 spécifie un élément de DN X.509 parmi
C,ST,L,O,OU,CN,T,I,G,S,D,UID,Email. A partir de la version
2.2.0 d'Apache, x509 peut aussi comporter un suffixe numérique
_n. Si le DN en question comporte plusieurs attributs de
noms identiques, ce suffixe constitue un index débutant à zéro et
permettant de sélectionner un
attribut particulier. Par exemple, si le DN sujet du certificat du
serveur comporte deux champs OU, on peut utiliser
SSL_SERVER_S_DN_OU_0 et SSL_SERVER_S_DN_OU_1
pour référencer chacun d'entre eux. Un nom de variable sans suffixe
_n est équivalent au même nom avec le suffixe
_0, ce qui correspond au premier attribut (ou au seul)
caractérisant le DN.
Lorsque la table d'environnement est remplie en utilisant l'option
StdEnvVars de la directive SSLOptions, le premier attribut (ou le
seul) caractérisant le DN est enregistré avec un nom sans suffixe ;
autrement dit, aucune entrée possédant comme suffixe _0
n'est enregistrée.
    


    A partir de la version 2.4.32 de httpd, on peut ajouter le suffixe
_RAW à x509 dans un composant DN afin d'empêcher la conversion
de la valeur de l'attribut en UTF-8. Il doit être placé après le suffixe index
(s'il existe). On utilisera par exemple SSL_SERVER_S_DN_OU_RAW ou
SSL_SERVER_S_DN_OU_0_RAW.
    


    Le format des variables *_DN a changé depuis la version
2.3.11 d'Apache HTTPD. Voir l'option LegacyDNStringFormat
de la directive SSLOptions pour
plus de détails.
    


    SSL_CLIENT_V_REMAIN n'est disponible qu'à partir de la
version 2.1.
    


    Plusieurs variables d'environnement additionnelles peuvent être
utilisées dans les expressions SSLRequire, ou
dans les formats de journalisation personnalisés :
    


    HTTP_USER_AGENT        PATH_INFO             AUTH_TYPE
HTTP_REFERER           QUERY_STRING          SERVER_SOFTWARE
HTTP_COOKIE            REMOTE_HOST           API_VERSION
HTTP_FORWARDED         REMOTE_IDENT          TIME_YEAR
HTTP_HOST              IS_SUBREQ             TIME_MON
HTTP_PROXY_CONNECTION  DOCUMENT_ROOT         TIME_DAY
HTTP_ACCEPT            SERVER_ADMIN          TIME_HOUR
THE_REQUEST            SERVER_NAME           TIME_MIN
REQUEST_FILENAME       SERVER_PORT           TIME_SEC
REQUEST_METHOD         SERVER_PROTOCOL       TIME_WDAY
REQUEST_SCHEME         REMOTE_ADDR           TIME
REQUEST_URI            REMOTE_USER
    


    Dans ces contextes, deux formats spéciaux peuvent aussi être utilisés
:
    


    
  
    ENV:nom_variable
    
  
    Correspond à la variable d'environnement standard
  nom_variable.
    

  
    HTTP:nom_en-tête
    
  
    Correspond à la valeur de l'en-tête de requête dont le nom est
  nom_en-tête.

    Formats de journaux
personnalisés
    


    Lorsque mod_ssl est compilé dans le serveur Apache
ou même chargé (en mode DSO), des fonctions supplémentaires sont
disponibles pour le Format de journal personnalisé du
module mod_log_config. A ce titre, la fonction de
format d'eXtension ``%{nom-var}x''
peut être utilisée pour présenter en extension toute variable fournie
par tout module, et en particulier celles fournies par mod_ssl et que
vous trouverez dans la table ci-dessus.
    

    
A des fins de compatibilité ascendante, il existe une fonction de format
cryptographique supplémentaire
``%{nom}c''. Vous trouverez toutes
les informations à propos de cette fonction dans le chapitre Compatibilité.
    

    Exemple
    CustomLog "logs/ssl_request_log" "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
    

    

    Ces formats sont disponibles même si l'option StdEnvVars de la
directive SSLOptions n'a pas été
définie.
    

    top
    

    

    Information à propos de la requête
    


    mod_ssl enregistre des informations à propos de la
requête que l'on peut restituer dans les journaux avec la chaîne de
format %{nom}n via le module
mod_log_config.
    


    Les informations enregistrées sont les suivantes :
    


    
  
    ssl-access-forbidden
    
  
    Cette information contient la valeur 1 si l'accès a
  été refusé suite à une directive SSLRequire ou
  SSLRequireSSL.
    

  
    ssl-secure-reneg
    
  
    Si mod_ssl a été compilé avec une version
  d'OpenSSL qui supporte la renégociation sécurisée, si SSL est utilisé
  pour la connexion courante et si le client supporte lui aussi la
  renégociation sécurisée, cette information contiendra la valeur
  1. Si le client ne supporte pas la renégociation
  sécurisée, l'information contiendra la valeur 0. Si
  mod_ssl n'a pas été compilé avec une version
  d'OpenSSL qui supporte la renégociation sécurisée, ou si SSL n'est pas
  utilisé pour la connexion courante, le contenu de l'information ne
  sera pas défini.
    

    


    top
    

    

    Extension pour l'interprétation
des expressions
    


    Lorsque mod_ssl est compilé statiquement avec
Apache, ou même chargé dynamiquement (en tant que module DSO), toute variable en provenance de mod_ssl peut
être utilisée pour l'interprétation des
expression ap_expr. Les variables peuvent être référencées en
utilisant la syntaxe ``%{varname}''.
A partir de la version 2.4.18, on peut aussi utiliser la syntaxe de
style mod_rewrite
``%{SSL:varname}'', ou la syntaxe de
style fonction ``ssl(varname)''.
    

    Exemple (en utilisant mod_headers)
    Header set X-SSL-PROTOCOL "expr=%{SSL_PROTOCOL}"
Header set X-SSL-CIPHER "expr=%{SSL:SSL_CIPHER}"
    

    

    Cette fonctionnalité est disponible même si l'option
StdEnvVars de la directive SSLOptions n'a pas été définie.
    

    top
    

    

    Fournisseurs d'autorisation
disponibles avec Require
    

  
    mod_ssl propose quelques fournisseurs
  d'autorisation à utiliser avec la directive Require du module
  mod_authz_core.
    

  
    Require ssl
    

    
    Le fournisseur ssl refuse l'accès si une connexion
    n'est pas chiffrée avec SSL. L'effet est similaire à celui de la
    directive SSLRequireSSL.
    


    
    Require ssl
    



  

  
    Require ssl-verify-client
    

    
    Le fournisseur ssl autorise l'accès si
    l'utilisateur est authentifié via un certificat client valide. Ceci
    n'a un effet que si SSLVerifyClient optional est actif.
    

    
    Dans l'exemple suivant, l'accès est autorisé si le client est
    authentifié via un certificat client ou par nom d'utilisateur/mot de
    passe :
    

    
    Require ssl-verify-client
Require valid-user

    Directive SSLCACertificateFile
    

    

    Description:Fichier contenant une concaténation des certificats de CA
codés en PEM pour l'authentification des clients
    

    Syntaxe:SSLCACertificateFile file-path
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_ssl
    

    

    
Cette directive permet de définir le fichier tout-en-un où vous
pouvez rassembler les certificats des Autorités de Certification (CAs)
pour les clients auxquels vous avez à faire. On les utilise pour
l'authentification des clients. Un tel fichier contient la simple
concaténation des différents fichiers de certificats codés en PEM, par
ordre de préférence. Cette directive peut être utilisée à la place et/ou
en complément de la directive SSLCACertificatePath.
    

    Exemple
    SSLCACertificateFile "/usr/local/apache2/conf/ssl.crt/ca-bundle-client.crt"
    

    


    

    top
    

    Directive SSLCACertificatePath
    

    

    Description:Répertoire des certificats de CA codés en PEM pour
l'authentification des clients
    

    Syntaxe:SSLCACertificatePath chemin-répertoire
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_ssl
    

    

    
Cette directive permet de définir le répertoire où sont stockés les
certificats des Autorités de Certification (CAs) pour les clients
auxquels vous avez à faire. On les utilise pour vérifier le certificat
du client au cours de l'authentification de ce dernier.
    

    
Les fichiers de ce répertoire doivent être codés en PEM et ils sont
accédés via des noms de fichier sous forme de condensés ou hash. Il ne
suffit donc pas de placer les fichiers de certificats dans ce répertoire
: vous devez aussi créer des liens symboliques nommés
valeur-de-hashage.N, et vous devez toujours vous
assurer que ce répertoire contient les liens symboliques appropriés.
    

    Exemple
    SSLCACertificatePath "/usr/local/apache2/conf/ssl.crt/"
    

    


    

    top
    

    Directive SSLCADNRequestFile
    

    

    Description:Fichier contenant la concaténation des certificats de CA
codés en PEM pour la définition de noms de CA acceptables
    

    Syntaxe:SSLCADNRequestFile file-path
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_ssl
    

    

    Lorsque mod_ssl demande un certificat client, une liste de noms
d'Autorités de Certification acceptables est envoyée au client au
cours de la phase d'initialisation de la connexion SSL. Le client peut
alors utiliser cette liste de noms de CA pour sélectionner un certificat
client approprié parmi ceux dont il dispose.
    


    Si aucune des directives SSLCADNRequestPath ou SSLCADNRequestFile n'est définie, la liste
de noms de CsA acceptables envoyée au client est la liste des noms de
tous les certificats de CA spécifiés par les directives SSLCACertificateFile et SSLCACertificatePath ; en d'autres termes,
c'est la liste des noms de CAs qui sera effectivement utilisée pour
vérifier le certificat du client.
    


    Dans certaines situations, il est utile de pouvoir envoyer
une liste de noms de CA acceptables qui diffère de la liste des CAs
effectivement utilisés pour vérifier le certificat du client ;
considérons par exemple le cas où le certificat du client est signé par
des CAs intermédiaires. On peut ici utiliser les directives SSLCADNRequestPath et/ou SSLCADNRequestFile, et les noms de CA
acceptables seront alors extraits de l'ensemble des certificats contenus
dans le répertoire et/ou le fichier définis par cette paire de
directives.
    


    SSLCADNRequestFile doit
spécifier un fichier tout-en-un contenant une concaténation des
certificats de CA codés en PEM.
    


    Exemple
    SSLCADNRequestFile "/usr/local/apache2/conf/ca-names.crt"

    Cette directive optionnelle permet de définir la liste de noms de

client est demandé. Voir la directive SSLCADNRequestFile pour plus de
détails.
    


    Les fichiers de ce répertoire doivent être codés en PEM et ils sont
accédés via des noms de fichier sous forme de condensés ou hash. Il ne
suffit donc pas de placer les fichiers de certificats dans ce répertoire
: vous devez aussi créer des liens symboliques nommés
valeur-de-hashage.N, et vous devez toujours vous
assurer que ce répertoire contient les liens symboliques appropriés.

Active la vérification des révocations basée sur les Listes de
Révocations de Certificats (CRL). Au moins une des directives SSLCARevocationFile ou SSLCARevocationPath doit être définie.
Lorsque cette directive est définie à chain (valeur
recommandée), les vérifications CRL sont effectuées sur tous les
certificats de la chaîne, alors que la valeur leaf limite
la vérification au certificat hors chaîne (la feuille).

    

    flags peut prendre comme valeurs 
    

      

    • no_crl_for_cert_ok

      
Avant la version 2.3.15, les vérifications CRL dans mod_ssl
réussissaient même si aucune CRL n'était trouvée dans les chemins
définis par les directives SSLCARevocationFile ou SSLCARevocationPath.
      

      Le comportement a
changé avec l'introduction de la  directive
SSLCARevocationFile : par défaut avec
chain ou leaf, les CRLs doivent être présentes pour que la
validation réussisse ; dans le cas contraire, elle échouera avec une
erreur "unable to get certificate CRL".
      

      La valeur no_crl_for_cert_ok du drapeau flag permet de
retrouver le comportement précédent.

    SSLCertificateChainFile est obsolète
    

    SSLCertificateChainFile est devenue obsolète avec la
version 2.4.8, lorsque la directive
SSLCertificateFile a été étendue
pour supporter aussi les certificats de CA intermédiaires dans le
fichier de certificats du serveur.
    

    

    
Cette directive permet de définir le fichier optionnel
tout-en-un où vous pouvez rassembler les certificats des
Autorités de Certification (CA) qui forment la chaîne de certification
du certificat du serveur. Cette chaîne débute par le certificat de la CA
qui a délivré le certificat du serveur et peut remonter jusqu'au
certificat de la CA racine. Un tel fichier contient la simple
concaténation des différents certificats de CA codés en PEM, en général
dans l'ordre de la chaîne de certification.
    

    Elle doit être utilisée à la place et/ou en complément de la
directive SSLCACertificatePath
pour construire explicitement la chaîne de certification du serveur qui
est envoyée au navigateur en plus du certificat du serveur. Elle s'avère
particulièrement utile pour éviter les conflits avec les certificats de
CA lorsqu'on utilise l'authentification du client. Comme le fait de
placer un certificat de CA de la chaîne de certification du serveur dans
la directive SSLCACertificatePath produit le même effet
pour la construction de la chaîne de certification, cette directive a
pour effet colatéral de faire accepter les certificats clients fournis
par cette même CA, au cours de l'authentification du client.
    

    
Soyez cependant prudent : fournir la chaîne de certification ne
fonctionne que si vous utilisez un simple certificat de
serveur RSA ou DSA. Si vous utilisez une paire de certificats
couplés RSA+DSA , cela ne fonctionnera que si les deux certificats
utilisent vraiment la même chaîne de certification. Dans le cas
contraire, la confusion risque de s'installer au niveau des
navigateurs.

    SSLCertificateChainFile "/usr/local/apache2/conf/ssl.crt/ca.crt"

    Directive SSLCertificateFile

codées au format PEM ou identificateur de jeton
    

    Syntaxe:SSLCertificateFile file-path|certid
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_ssl
    

    Compatibilité:L'option certid est disponible à partir de la version
2.4.42 du serveur HTTP Apache.
    

    

    Cette directive permet de définir le fichier de données contenant les
informations de certificat X.509 du serveur codées au format PEM ou
l'identificateur de certificat via un jeton cryptographique. Si on utilise un
fichier au format PEM, ce dernier doit contenir au minimum un certificat
d'entité finale (feuille).
La directive peut être utilisée plusieurs fois (elle référence des
fichiers différents) pour accepter plusieurs algorithmes
d'authentification au niveau du serveur - souvent RSA, DSA et ECC. Le
nombre d'algorithmes supportés dépend de la version d'OpenSSL utilisée
avec mod_ssl : à partir de la version 1.0.0, la commande openssl
list-public-key-algorithms affiche la liste des algorithmes
supportés. Voir aussi la note ci-dessous à propos des limitations des versions
d'OpenSSL antérieures à 1.0.2 et la manière de les contourner.

    


    Les fichiers peuvent aussi contenir des certificats de CA
intermédiaires triés depuis la feuille vers la racine. Cette
fonctionnalité est disponible depuis la version 2.4.8 du serveur HTTP
Apache, et rend obsolète la directive SSLCertificateChainFile. A partir de la
version 1.0.2 d'OpenSSL, il est alors possible de configurer la chaîne
de certification en fonction du certificat.
    


    Depuis la version 2.4.7 du serveur HTTP Apache, on peut aussi ajouter
des paramètres DH personnalisés et un nom EC
curve pour les clés éphémères à la fin du premier fichier défini par la
directive SSLCertificateFile.
Ces paramètres peuvent être générés avec les commandes openssl
dhparam et openssl ecparam, et ils peuvent être
ajoutés tel quel à la fin du premier fichier de certificat. En effet,
seul le premier fichier de certificat défini peut être utilisé pour
enregistrer des paramètres personnalisés, car ces derniers s'appliquent
indépendamment de l'algorithme d'authentification utilisé.

    


    Enfin, il est aussi possible d'ajouter la clé privée du certificat de
l'entité finale au fichier de certificat, ce qui permet de se passer
d'une directive SSLCertificateKeyFile séparée. Cette
pratique est cependant fortement déconseillée. En effet, les fichiers de
certificats qui contiennent de tels clés embarquées doivent être définis
avant les certificats en utilisant un fichier de clé séparé. En outre,
si la clé est chiffrée, une boîte de dialogue pour entrer le mot de
passe de la clé s'ouvre au démarrage du serveur.

    


    Plutôt que de stocker les certificats et les clés privées dans des fichiers,
on peut utiliser un identificateur de certificat pour identifier un certificat
stocké dans un jeton. Actuellement, seuls les URIs PKCS#11 sont reconnus comme
identificateurs de certificats et peuvent être utilisés en conjonction avec le
moteur OpenSSL pkcs11. Si la directive SSLCertificateKeyFile est absente, le certificat et
la clé privée peuvent être chargés avec l'identificateur spécifié via la
directive SSLCertificateFile.
    


    

    Interopérabilité des paramètres DH avec les nombres premiers de
plus de 1024 bits
    

    
Depuis la version 2.4.7, mod_ssl utilise des
paramètres DH standardisés avec des nombres premiers de 2048, 3072 et
4096 bits, et avec des nombres premiers de 6144 et 8192 bits depuis la
version 2.4.10 (voir RFC
3526), et les fournit aux clients en fonction de la longueur de la
clé du certificat RSA/DSA. En particulier avec les clients basés sur
Java (versions 7 et antérieures), ceci peut provoquer des erreurs au
cours de la négociation - voir cette réponse de la FAQ SSL pour
contourner les problèmes de ce genre.

    

    


    

    Paramètres DH par défaut lorsqu'on utilise plusieurs certificats et une
version d'OpenSSL antérieure à 1.0.2.
    

    
Lorsqu'on utilise plusieurs certificats pour supporter différents algorithmes
d'authentification (comme RSA, DSA, mais principalement ECC) et une
version d'OpenSSL antérieure à 1.0.2, il est recommandé soit d'utiliser des
paramètres DH spécifiques (solution à privilégier) en les ajoutant au premier
fichier certificat (comme décrit ci-dessus), soit d'ordonner les directives
SSLCertificateFile de façon à ce que les certificats
RSA/DSA soit placés après les certificats ECC.

    

    
Cette limitation est présente dans les anciennes versions d'OpenSSL qui
présentent toujours le dernier certificat configuré, au lieu
de laisser le serveur HTTP Apache déterminer le certificat sélectionné lors de
la phase de négociation de la connexion (lorsque les paramètres DH doivent être
envoyés à l'hôte distant).
De ce fait, le serveur peut sélectionner des paramètres DH par défaut basés sur
la longueur de la clé du mauvais certificat (les clés ECC sont beaucoup plus
petites que les clés RSA/DSA et leur longueur n'est pas pertinente pour la
sélection des nombres premiers DH).

    

    
Ce problème peut être résolu en créant et configurant des paramètres DH
spécifiques (comme décrit ci-dessus), car ils l'emportent toujours sur les
paramètres DH par défaut, et vous pourrez ainsi utiliser une longueur spécifique
et appropriée.

Cette directive peut être utilisée plusieurs fois pour référencer
différents noms de fichiers, afin de supporter plusieurs algorithmes
pour l'authentification du serveur. A chaque directive SSLCertificateKeyFile doit être associée
une directive SSLCertificateFile correspondante.

    


    
La clé privé peut aussi être ajoutée au fichier défini par la directive

Cette directive complexe utilise la chaîne cipher-spec
contenant la liste des algorithmes de chiffrement OpenSSL que le client
peut utiliser au cours de la phase d'initialisation de la connexion SSL. La
spécification optionnelle du protocole permet de configurer la suite
d'algorithmes de chiffrement pour une version spécifique de SSL. Une des valeurs
possibles est "SSL" pour toutes les versions du protocole SSL jusqu'à TLSv1.2
compris.

    

    
Notez que cette directive peut être utilisée aussi bien dans un contexte
de serveur que dans un contexte de répertoire. Dans un contexte de
serveur, elle s'applique à l'initialisation SSL standard lorsqu'une
connexion est établie. Dans un contexte de répertoire, elle force une
renégociation SSL avec la liste d'algorithmes de chiffrement spécifiée
après la lecture d'une requête HTTP, mais avant l'envoi de la réponse
HTTP.
    

    
Si la bibliothèque SSL supporte TLSv1.3 (versions d'OpenSSL 1.1.1 et
supérieures), il est possible de spécifier le paramètre "TLSv1.3" pour
configurer la suite d'algorithmes de chiffrement pour ce protocole. Comme
TLSv1.3 n'autorise pas la renégociation, spécifier pour lui des algorithmes de
chiffrement dans un contexte de répertoire n'est pas autorisé
    

    
Pour obtenir la liste des noms d'algorithmes de chiffrement pour TLSv1.3, se
référer à la the
OpenSSL documentation.
    

    
La liste d'algorithmes de chiffrement SSL spécifiée par l'argument
cipher-spec comporte quatre attributs principaux auxquels
s'ajoutent quelques attributs secondaires :
    

      

    • Algorithme d'échange de clés:
      
    RSA, Diffie-Hellman, Elliptic Curve Diffie-Hellman, Secure Remote Password.

      • 

    • Algorithme d'authentification:
      
    RSA, Diffie-Hellman, DSS, ECDSA, ou none.

      • 

    • Algorithme de chiffrement:
      
    AES, DES, Triple-DES, RC4, RC2, IDEA, etc...

      • 

    • Algorithme de condensé MAC:
      
    MD5, SHA ou SHA1, SHA256, SHA384.

      • 

    

    L'algorithme de chiffrement peut aussi provenir de l'extérieur. Les
algorithmes SSLv2 ne sont plus supportés.
Pour définir les algorithmes à utiliser, on
peut soit spécifier tous les algorithmes à la fois, soit utiliser des
alias pour spécifier une liste d'algorithmes dans leur ordre de
préférence (voir Table 1). Les algorithmes et
alias effectivement disponibles dépendent de la version d'openssl
utilisée. Les versions ultérieures d'openssl sont susceptibles d'inclure
des algorithmes supplémentaires.

Cela devient intéressant lorsque tous ces symboles sont combinés
ensemble pour spécifier les algorithmes disponibles et l'ordre dans
lequel vous voulez les utiliser. Pour simplifier tout cela, vous
disposez aussi d'alias (SSLv3, TLSv1, EXP, LOW, MEDIUM,
HIGH) pour certains groupes d'algorithmes. Ces symboles peuvent
être reliés par des préfixes pour former la chaîne algorithmes.
Les préfixes disponibles sont :
    

      

    • none: ajoute l'algorithme à la liste
      • 

    • +: déplace les algorithmes qui conviennent à la
place courante dans la liste
      • 

    • -: supprime l'algorithme de la liste (peut être rajouté
plus tard)
      • 

    • !: supprime définitivement l'algorithme de la liste (ne
peut plus y être rajouté plus tard)
      • 

    


    

    Les algorithmes aNULL, eNULL et
EXP sont toujours désactivés
    

    Depuis la version 2.4.7, les
algorithmes de type null ou destinés à l'exportation sont toujours
désactivés car mod_ssl ajoute obligatoirement
!aNULL:!eNULL:!EXP à toute chaîne d'algorithme de
chiffrement à l'initialisation.
    

    


    Pour vous simplifier la vie, vous pouvez utiliser la commande
``openssl ciphers -v'' qui vous fournit un moyen simple de
créer la chaîne algorithmes avec succès. La chaîne
algorithmes par défaut dépend de la version des bibliothèques
SSL installées. Supposons qu'elle contienne
``RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5'', ce qui
stipule de mettre RC4-SHA et AES128-SHA en
premiers, car ces algorithmes présentent un bon compromis entre vitesse
et sécurité. Viennent ensuite les algorithmes de sécurité élevée et
moyenne. En fin de compte, les algorithmes qui n'offrent aucune
authentification sont exclus, comme les algorithmes anonymes
Diffie-Hellman pour SSL, ainsi que tous les algorithmes qui utilisent
MD5 pour le hashage, car celui-ci est reconnu comme
insuffisant.
    

    $ openssl ciphers -v 'RC4-SHA:AES128-SHA:HIGH:MEDIUM:!aNULL:!MD5'
RC4-SHA                 SSLv3 Kx=RSA      Au=RSA  Enc=RC4(128)  Mac=SHA1

Cette directive permet d'activer l'utilisation d'une carte accélératrice
de chiffrement qui prendra en compte certaines parties du traitement
relatif à SSL. Cette directive n'est utilisable que si la boîte à
outils SSL à été compilée avec le support "engine" ; les versions 0.9.7
et supérieures d'OpenSSL possèdent par défaut le support "engine", alors
qu'avec la version 0.9.6, il faut utiliser les distributions séparées
"-engine".
    


    Pour déterminer les moteurs supportés, exécutez la commande
"openssl engine".

Cette directive permet d'activer/désactiver le moteur du protocole
SSL/TLS. Elle doit être utilisée dans une section <VirtualHost> pour activer
SSL/TLS pour ce serveur virtuel particulier. Par défaut, le moteur du
protocole SSL/TLS est désactivé pour le serveur principal et tous les
serveurs virtuels configurés.
    

    Exemple
    <VirtualHost _default_:443>
SSLEngine on
#...
</VirtualHost>
    

    

    Depuis la version 2.1 d'Apache, la directive
SSLEngine peut être définie à
optional, ce qui active le support de RFC 2817, Upgrading to
TLS Within HTTP/1.1. Pour le moment, aucun navigateur web ne supporte
RFC 2817.

Cette directive permet d'activer/désactiver l'utilisation du drapeau
FIPS_mode de la bibliothèque SSL. Elle doit être définie dans le
contexte du serveur principal, et n'accepte pas les configurations
sources de conflits (SSLFIPS on suivi de SSLFIPS off par exemple). Le
mode s'applique à toutes les opérations de la bibliothèque SSL.

    

    
Si httpd a été compilé avec une bibliothèque SSL qui ne supporte pas le
drapeau FIPS_mode, la directive SSLFIPS on échouera.
Reportez-vous au document sur la politique de sécurité FIPS 140-2 de la
bibliothèque du fournisseur SSL, pour les prérequis spécifiques
nécessaires à l'utilisation de mod_ssl selon un mode d'opération
approuvé par FIPS 140-2 ; notez que mod_ssl en lui-même n'est pas
validé, mais peut être décrit comme utilisant un module de chiffrement
validé par FIPS 140-2, lorsque tous les composants sont assemblés et mis
en oeuvre selon les recommandations de la politique de sécurité
applicable.

    Compatibilité:Disponible depuis httpd 2.2.15, si une version 0.9.8m
ou supérieure d'OpenSSL est utilisée
    

    

    Comme il a été spécifié, toutes les versions des protocoles SSL et
TLS (jusqu'à la version 1.2 de TLS incluse) étaient vulnérables à une
attaque de type Man-in-the-Middle (CVE-2009-3555)
au cours d'une renégociation. Cette vulnérabilité permettait à un
attaquant de préfixer la requête HTTP (telle qu'elle était vue du
serveur) avec un texte choisi. Une extension du protocole a été
développée pour corriger cette vulnérabilité, sous réserve qu'elle soit
supportée par le client et le serveur.
    


    Si mod_ssl est lié à une version 0.9.8m ou
supérieure d'OpenSSL, par défaut, la renégociation n'est accordée qu'aux
clients qui supportent la nouvelle extension du protocole. Si
cette directive est activée, la renégociation sera accordée aux anciens
clients (non patchés), quoique de manière non sécurisée
    


    Avertissement à propos de la sécurité
    

    Si cette directive est activée, les connexions SSL seront vulnérables
aux attaques de type préfixe Man-in-the-Middle comme décrit dans CVE-2009-3555.
    

    


    Exemple
    SSLInsecureRenegotiation on
    

    


    La variable d'environnement SSL_SECURE_RENEG peut être
utilisée dans un script SSI ou CGI pour déterminer si la renégociation
sécurisée est supportée pour une connexion SSL donnée.

    Cette directive permet à mod_ssl d'accéder à l'API SSL_CONF
d'OpenSSL. Il n'est ainsi plus nécessaire d'implémenter des
directives supplémentaires pour mod_ssl lorsque de nouvelles
fonctionnalités sont ajoutées à OpenSSL, ce qui rend la configuration de
ce dernier beaucoup plus souple.
    


    Le jeu de commandes disponibles pour la directive
SSLOpenSSLConfCmd dépend de la version d'OpenSSL
utilisée pour mod_ssl (la version minimale 1.0.2 est un
prérequis). Pour obtenir la liste des commandes supportées, voir la
section Supported configuration file commands de la page de
manuel d'OpenSSL SSL_CONF_cmd(3).
    


    Certaines commandes peuvent remplacer des directives existantes

    Directive SSLOptions

    Surcharges autorisées:Options
    

    Statut:Extension
    

    Module:mod_ssl
    

    

    
Cette directive permet de contrôler différentes options d'exécution du
moteur SSL dans un contexte de répertoire. Normalement, si plusieurs
SSLOptions peuvent s'appliquer à un répertoire, c'est la
plus spécifique qui est véritablement prise en compte ; les options ne
se combinent pas entre elles. Elles se combinent cependant entre elles
si elles sont toutes précédées par un symbole plus
(+) ou moins (-). Toute option précédée d'un
+ est ajoutée aux options actuellement en vigueur, et toute
option précédée d'un - est supprimée de ces mêmes
options.

    

    
Les options disponibles sont :
    

      

    • StdEnvVars
    
      
    Lorsque cette option est activée, le jeu standard de variables
    d'environnement SSL relatives à CGI/SSI est créé. Cette option est
    désactivée par défaut pour des raisons de performances, car
    l'extraction des informations constitue une opération assez coûteuse
    en ressources. On n'active donc en général cette option que pour les
    requêtes CGI et SSI.
      

      • 

    • ExportCertData
    
      
    Lorsque cette option est activée, des variables d'environnement
    CGI/SSI supplémentaires sont créées : SSL_SERVER_CERT,
    SSL_CLIENT_CERT et
    SSL_CLIENT_CERT_CHAIN_n (avec n =
    0,1,2,..). Elles contiennent les certificats X.509 codés en PEM du
    serveur et du client pour la connexion HTTPS courante, et peuvent
    être utilisées par les scripts CGI pour une vérification de
    certificat plus élaborée. De plus, tous les autres certificats de la
    chaîne de certificats du client sont aussi fournis. Tout ceci gonfle
    un peu l'environnement, et c'est la raison pour laquelle vous ne
    devez activer cette option qu'à la demande.
      

      • 

    • FakeBasicAuth
    
      
    Lorsque cette option est activée, le Nom Distinctif (DN) sujet du
    certificat client X509 est traduit en un nom d'utilisateur pour
    l'autorisation HTTP de base. Cela signifie que les méthodes
    d'authentification standard d'Apache peuvent être utilisées pour le
    contrôle d'accès. Le nom d'utilisateur est tout simplement le Sujet
    du certificat X509 du client (il peut être déterminé en utilisant la
    commande OpenSSL openssl x509 : openssl x509
    -noout -subject -in certificat.crt).
    Notez qu'aucun mot de passe n'est envoyé par l'utilisateur. Chaque
    entrée du fichier des utilisateurs doit comporter ce mot de passe :
    ``xxj31ZMTZzkVA'', qui est la version chiffrée en DES
    du mot ``password''. Ceux qui travaillent avec un
    chiffrement basé sur MD5 (par exemple sous FreeBSD ou BSD/OS,
    etc...) doivent utiliser le condensé MD5 suivant pour le même mot :
    ``$1$OXLyS...$Owx8s2/m9/gfkcRVXzgoE/''.
      

    
      Notez que la directive AuthBasicFake implémentée par le
    module mod_auth_basic peut être utilisée d'une
    manière plus générale comme simulation d'authentification basique,
    ce qui permet de contrôler la structure nom utilisateur/mot de
    passe.
      

      • 

    • StrictRequire
    
      
    Cette option force l'interdiction d'accès lorsque
    SSLRequireSSL ou SSLRequire a décidé que
    l'accès devait être interdit. Par défaut, dans le cas où
    une directive ``Satisfy any'' est utilisée, et si
    d'autres restrictions d'accès ont été franchies, on passe en général
    outre l'interdiction d'accès due à SSLRequireSSL ou
    SSLRequire (parce que c'est ainsi que le mécanisme
    Satisfy d'Apache doit fonctionner). Pour des
    restrictions d'accès plus strictes, vous pouvez cependant utiliser
    SSLRequireSSL et/ou SSLRequire en
    combinaison avec une option ``SSLOptions
    +StrictRequire''. Une directive ``Satisfy Any''
    n'a alors aucune chance d'autoriser l'accès si mod_ssl a décidé de
    l'interdire.
      

      • 

    • OptRenegotiate
    
      
    Cette option active la gestion optimisée de la renégociation des
    connexions SSL intervenant lorsque les directives SSL sont utilisées
    dans un contexte de répertoire. Par défaut un schéma strict est
    appliqué, et chaque reconfiguration des paramètres SSL au
    niveau du répertoire implique une phase de renégociation SSL
    complète. Avec cette option, mod_ssl essaie d'éviter les
    échanges non nécessaires en effectuant des vérifications de
    paramètres plus granulaires (mais tout de même efficaces).
    Néanmoins, ces vérifications granulaires peuvent ne pas correspondre
    à ce qu'attend l'utilisateur, et il est donc recommandé de n'activer
    cette option que dans un contexte de répertoire.
      

      • 

    • LegacyDNStringFormat
    
      
    Cette option permet d'agir sur la manière dont les valeurs des
    variables SSL_{CLIENT,SERVER}_{I,S}_DN sont formatées.
    Depuis la version 2.3.11, Apache HTTPD utilise par défaut un format
    compatible avec la RFC 2253. Ce format utilise des virgules comme
    délimiteurs entre les attributs, permet l'utilisation de caractères
    non-ASCII (qui sont alors convertis en UTF8), échappe certains
    caractères spéciaux avec des slashes inversés, et trie les attributs
    en plaçant l'attribut "C" en dernière position.
      

    
      Si l'option LegacyDNStringFormat est présente, c'est
    l'ancien format qui sera utilisé : les attributs sont triés avec
    l'attribut "C" en première position, les séparateurs sont des
    slashes non inversés, les caractères non-ASCII ne sont pas supportés
    et le support des caractères spéciaux n'est pas fiable.

Lors de son démarrage, Apache doit lire les différents fichiers de
certificats (voir la directive SSLCertificateFile) et de clés privées
(voir la directive SSLCertificateKeyFile) des serveurs
virtuels où SSL est activé. Comme, pour des raisons de sécurité, les
fichiers de clés privées sont en général chiffrés,  mod_ssl doit
demander à l'administrateur un mot de passe pour déchiffrer ces
fichiers. L'argument type permet de choisir la manière dont
cette demande peut être formulée parmi les trois suivantes :
    

      

    • builtin
    
      
    C'est la méthode par défaut, et un dialogue interactive de terminal
    s'ouvre au cours du démarrage juste avant qu'Apache ne se détache du
    terminal. A ce moment, l'administrateur doit entrer manuellement un
    mot de passe pour chaque fichier de clé privée chiffré. Etant donné
    qu'il peut y avoir un grand nombre de serveurs virtuels configurés
    avec SSL activé, le protocole de réutilisation suivant est utilisé
    pour minimiser le dialogue : lorsqu'un fichier de clé privée est
    chiffré, tous les mots de passe connus (au début, il n'y en a aucun,
    bien entendu) sont essayés. Si l'un de ces mots de passe connus
    convient, aucun dialogue ne s'ouvrira pour ce fichier de
    clé privée particulier. Si aucun ne convient, un autre mot de passe
    sera demandé à partir du terminal et sera mis en mémoire pour le
    fichier de clé privée suivant (pour lequel il pourra éventuellement
    être réutilisé).
      
    
      
    Cette méthode confère à mod_ssl une grande souplesse (car pour N
    fichiers de clé privée chiffrés, vous pouvez utiliser N
    mots de passe différents - mais vous devrez alors tous les fournir,
    bien entendu), tout en minimisant le dialogue de terminal (vous
    pouvez en effet utiliser un seul mot de passe pour les N fichiers de
    clé privée et vous n'aurez alors à l'entrer qu'une seule
    fois).
      • 


    • |/chemin/vers/programme [arguments...]

   
      Ce mode permet d'utiliser un programme externe qui va se présenter
   comme une redirection vers un périphérique d'entrée particulier ; le
   texte de prompt standard utilisé pour le mode builtin
   est envoyé au programme sur stdin, et celui-ci doit
   renvoyer des mots de passe sur stdout. Si
   plusieurs mots de passe sont requis (ou si un mot de passe incorrect
   a été entré), un texte de prompt supplémentaire sera écrit après le
   retour du premier mot de passe, et d'autres mots de passe devront
   alors être réécrits.
      • 


    • exec:/chemin/vers/programme
    
      
    Ici, un programme externe est appelé au démarrage du serveur pour
    chaque fichier de clé privée chiffré.Il est appelé avec deux
    arguments (le premier est de la forme
    ``nom-serveur:port'', le second
    est ``RSA'', ``DSA'', ``ECC''
    ou un index entier commençant à 3 si plus de 3 clés ont été
    configurées), qui
    indiquent pour quels serveur et algorithme il doit écrire le mot de
    passe correspondant sur stdout. Avec les versions 2.4.8
    (non réalisée) et
    2.4.9, il est appelé avec un seul argument, une chaîne de la forme
    "servername:portnumber:index" (où index
    est un nombre entier commençant à zéro), qui spécifie le serveur,
    le port TCP et un numéro de certificat. Le but recherché est
    l'exécution de vérifications de sécurité préalables permettant de
    s'assurer que le système n'est pas victime d'une attaque, et de ne
    fournir le mot de passe que si toutes les vérifications ont été
    effectuées avec succès.
      
    
      
    Ces vérifications de sécurité, ainsi que la manière dont le mot de
    passe est déterminé peuvent être aussi sophistiqués que vous le
    désirez. Mod_ssl ne définit que l'interface : un programme
    exécutable qui écrit le mot de passe sur stdout. Ni
    plus, ni moins ! Ainsi, si vous êtes vraiment paranoïaque en matière
    de sécurité, voici votre interface. Tout le reste doit être confié à
    l'administrateur à titre d'exercice, car les besoins en sécurité
    locale sont très différents.
      
    
      
    L'algorithme de réutilisation est utilisé ici aussi. En d'autres
    termes, le programme externe n'est appelé qu'une fois par mot de
    passe unique.

Cette directive permet de définir quelles versions du protocole SSL/TLS
seront acceptées lors de l'initialisation d'une nouvelle connexion.
    

    
Les protocoles disponibles sont les suivants (sensibles à la
casse) :
    

      

    • SSLv3
    
      
    Il s'agit du protocole Secure Sockets Layer (SSL) version 3.0 de
    Netscape Corporation. C'est le successeur de SSLv2 et le
    prédécesseur de TLSv1, mais est considéré comme
    obsolète dans la RFC
    7568
      • 


    • TLSv1
    
      
    Il s'agit du protocole  Transport Layer Security (TLS) version 1.0.
    C'est le successeur de SSLv3, et il est défini dans la RFC2246. Il est
    supporté par la plupart des clients.
      • 


    • TLSv1.1 (à partir de la version 1.0.1 d'OpenSSL)
    
      
    Une révision du protocole TLS 1.0 définie dans la RFC 4346.
      • 


    • TLSv1.2 (à partir de la version 1.0.1 d'OpenSSL)
    
      
    Une révision du protocole TLS 1.1 définie dans la RFC 5246.
      • 


    • TLSv1.3 (à partir de la version 1.1.1 d'OpenSSL)
     
      
     Une nouvelle version du protocole TLS définie dans la RFC 8446.
      • 


    • all
    
      
    C'est un raccourci pour ``+SSLv3 +TLSv1'' ou - à partir
    de la version 1.0.1 d'OpenSSL - ``+SSLv3 +TLSv1 +TLSv1.1
    +TLSv1.2'' (sauf si OpenSSL a été compilé avec l'option
    ``no-ssl3'', auquel cas all n'inclura pas
    +SSLv3).
      • 

    

    Exemple
    SSLProtocol TLSv1
    

    

    

    La directive SSLProtocol et les serveurs virtuels
basés sur le nom
    

    
Avant OpenSSL 1.1.1, et même si l'indication du nom de serveur (Server Name
Indication ou SNI) permettait de déterminer le serveur virtuel cible assez tôt
au cours de la négociation TLS, il était impossible de changer de version de
protocole TLS à ce point, si bien que le SSLProtocol
négocié se basait toujours sur celui du serveur virtuel de base (le
premier serveur virtuel déclaré avec le couple IP:port de la
connexion).

    

    
A partir de la version 2.4.42, si le serveur HTTP Apache est compilé avec une
version 1.1.1. ou supérieure d'OpenSSL, et si le client fournit la SNI dans la
négociation TLS, le SSLProtocol de chaque serveur virtuel
(basé sur le nom) pourra être pris en compte et le sera.

    

    
A des fins de compatibilité avec les versions précédentes, si un serveur virtuel
basé sur le nom n'a aucune directive SSLProtocol définie,
c'est le protocole du serveur virtuel de base qui s'appliquera, à
moins qu'une directive SSLProtocol ne soit
configurée au niveau global, auquel cas c'est le protocole défini par cette
directive qui s'appliquera (ce dernier cas relève cependant plus d'un
comportement logique que d'un souci de compatibilité).

Cette directive permet de spécifier le répertoire où sont stockés les

certificat du serveur distant lors de l'authentification de ce

Les fichiers de ce répertoire doivent être codés en PEM et ils sont
accédés via des noms de fichier sous forme de condensés ou hash. Il ne

valeur-de-hashage.N, et vous devez toujours vous
assurer que ce répertoire contient les liens symboliques appropriés.

Active la vérification des révocations basée sur les Listes de
révocations de Certificats (CRL) pour les serveurs distants
auxquels vous vous connectez. A moins une des directives SSLProxyCARevocationFile ou SSLProxyCARevocationPath doit être définie.
Lorsque cette directive est définie à chain (valeur
recommandée), les vérifications CRL sont effectuées sur tous les
certificats de la chaîne, alors que la valeur leaf limite
la vérification au certificat hors chaîne (la feuille).

    

    

    Lorsque la directive est définie à chain ou
leaf, les CRLs doivent être disponibles pour que la
validation réussisse
    

    
Avant la version 2.3.15, les vérifications CRL dans mod_ssl
réussissaient même si aucune CRL n'était trouvée dans les chemins
définis par les directives SSLProxyCARevocationFile ou SSLProxyCARevocationPath. Le comportement a
changé avec l'introduction de cette directive : lorsque la vérification
est activée, les CRLs doivent être présentes pour que la
validation réussisse ; dans le cas contraire, elle échouera avec une
erreur "CRL introuvable".

    Compatibilité:Le contexte d'une section proxy est supporté à partir de la

Cette directive permet de définir si le champ CN du certificat du serveur
distant doit être comparé au nom de serveur de l'URL de la requête. S'ils ne
correspondent pas, un code d'état 502 (Bad Gateway) est envoyé. A partir de la
version 2.4.5, SSLProxyCheckPeerCN a été remplacé par SSLProxyCheckPeerName.

    

    
De la version 2.4.5 à la version 2.4.20, spécifier SSLProxyCheckPeerName
off était suffisant pour obtenir ce comportement (car la valeur par
défaut de SSLProxyCheckPeerCN était on). Avec ces
versions, les deux directives doivent être définies à off pour
éviter toute validation du nom de certificat du serveur distant, et de
nombreux utilisateurs ont signalé ce comportement comme très perturbant.

    

    
A partir de la version 2.4.21, toutes les configurations qui activent au moins
une des deux directives SSLProxyCheckPeerName ou
SSLProxyCheckPeerCN adopteront le nouveau comportement de la
directive SSLProxyCheckPeerName, et
toutes les configurations qui désactivent une des deux directives
SSLProxyCheckPeerName ou SSLProxyCheckPeerCN
éviteront toute validation du nom de certificat du serveur distant. Seule la
configuration suivante permettra de retrouver la comparaison de CN
traditionnelle pour les versions 2.4.21 et supérieures :

Apache
    
Le contexte d'une section proxy est supporté à partir de la
version 2.4.30 du serveur HTTP Apache
    

    

    
Cette directive permet de configurer la vérification du nom d'hôte pour
les certificats serveur lorsque mod_ssl agit en tant que client SSL. La
vérification réussit si le nom d'hôte de l'URI de la requête correspond à un
des attributs CN du sujet du certificat, ou à l'extension subjectAltName. Si la
vérification échoue, la requête SSL
avorte, et un code d'erreur 502 (Bad Gateway) est renvoyé.

    

    
Les caractères génériques sont supportés dans certains cas bien spécifiques :
une entrée subjectAltName de type dNSName ou les attributs CN
commençant par *. correspondront à tout nom d'hôte comportant
le même nombre de champs et le même suffixe ; par exemple,
*.example.org correspondra à foo.example.org,
mais pas à foo.bar.example.org car le nombre d'éléments dans les
nom est différent.

    

    
Cette fonctionnalité a été introduite avec la version 2.4.5 et l'emporte sur la
directive SSLProxyCheckPeerCN qui ne
comparait que la valeur exacte du premier attribut CN avec le nom d'hôte.
Cependant, de nombreux utilisateurs étaient déconcertés par le comportement
induit par l'utilisation de ces deux directives individuellement, si bien que ce
comportement a été amélioré avec la version 2.4.21. Voir la description de la
directive SSLProxyCheckPeerCN pour le
comportement original et des détails à propos de ces améliorations.

Cette directive permet d'activer/désactiver l'utilisation du moteur de

dans le cadre d'un mandataire pour un serveur virtuel particulier. Par
défaut, le moteur de protocole SSL/TLS est désactivé pour la fonction de
mandataire du serveur principal et de tous les serveurs virtuels
configurés.
    


    Notez que la directive SSLProxyEngine ne doit
généralement pas être utilisée dans le cadre d'un serveur virtuel qui agit en

SSLProxyEngine n'est pas nécessaire pour activer un

Cette directive permet de définir le fichier tout-en-un où sont stockés
les clés et certificats permettant au serveur mandataire de
s'authentifier auprès des serveurs distants.

    

    
Le fichier spécifié est la simple concaténation des différents fichiers de
certificats codés en PEM. Cette directive s'utilise à la place ou en complément
de la directive SSLProxyMachineCertificatePath. Le fichier spécifié
peut contenir un nombre quelconque de paires certificat client/clé privée
associée, et chaque paire peut être spécifiée selon l'ordre (certificat, clé) ou
(clé, certificat). Des certificats non-feuilles (CA) peuvent aussi être inclus
dans le fichier et sont traités comme s'ils avaient été définis via la directive
SSLProxyMachineCertificateChainFile.

    


    Lorsqu'un serveur distant sollicite le serveur pour obtenir un certificat
client, ce dernier doit fournir une liste de noms d'autorités de
certification acceptables au cours de la négociation. Si cette liste n'est
pas fournie, mod_ssl utilisera la première paire certificat/clé
client définie. Si par contre cette liste est fournie,
mod_ssl va la parcourir afin de trouver un certificat client
défini qui a été fourni soit directement par l'autorité de certification
considérée, soit indirectement via un nombre quelconque de certificats d'autorités de
certification intermédiaires. La chaîne de certificats d'autorités de
certification intermédiaires peut être construite à partir de ceux qui sont
inclus dans le fichier ou configurés
via la directive SSLProxyMachineCertificateChainFile. Le premier
certificat défini correspondant sera alors fourni comme réponse au cours de la
négociation
    


    Si la liste de noms de CA est fournie au serveur distant, et si
aucun certificat client correspondant n'est trouvé, aucun certificat

    Lorsqu'un mandataire est configuré pour faire suivre les requêtes
vers un serveur SSL distant, cette directive permet de configurer la
vérification du certificat de ce serveur distant.
    


    
Les valeurs de niveaux disponibles sont les suivantes :
    

      

    • none:
     aucun certificat n'est requis pour le serveur distant
      • 

    • optional:
     le serveur distant peut présenter un certificat valide
      • 

    • require:
     le serveur distant doit présenter un certificat valide
      • 

    • optional_no_ca:
     le serveur distant peut présenter un certificat valide
      
     mais il n'est pas nécessaire qu'il soit vérifiable (avec succès).
      • 

    

    En pratique, seuls les niveaux none et
require sont vraiment intéressants, car le niveau
optional ne fonctionne pas avec tous les serveurs, et
le niveau optional_no_ca va tout à fait à l'encontre de
l'idée que l'on peut se faire de l'authentification (mais peut tout de
même être utilisé pour établir des pages de test SSL, etc...).

Cette directive permet de définir le niveau de profondeur maximum
jusqu'auquel mod_ssl doit aller au cours de sa vérification avant de
décider que le serveur distant ne possède pas de certificat valide.
    

    
La profondeur correspond en fait au nombre maximum de fournisseurs de
certificats intermédiaires, c'est à dire le nombre maximum de
certificats
de CA que l'on peut consulter lors de la vérification du certificat du
serveur distant. Une profondeur de 0 signifie que seuls les certificats
de serveurs distants auto-signés sont acceptés, et la profondeur par
défaut de 1 que le certificat du serveur distant peut être soit
auto-signé, soit signé par une CA connue directement du serveur (en
d'autres termes, le certificat de CA est référencé par la directive
SSLProxyCACertificatePath),
etc...

    Contexte:configuration globale
    

    Statut:Extension
    

    Module:mod_ssl
    

    

    
Cette directive permet de définir une ou plusieurs sources de
déclenchement du Générateur de Nombres Pseudo-Aléatoires (PRNG) dans
OpenSSL au démarrage du serveur (si contexte a pour valeur
startup) et/ou juste avant l'établissement d'une nouvelle
connexion SSL (si contexte a pour valeur connect).
Cette directive ne peut être utilisée qu'au niveau du serveur global car
le PRNG est un service global.
    

    
Les différentes valeurs de source disponibles sont :
    

      

    • builtin
    
      Cette source de déclenchement intégrée est toujours disponible.  Son
    utilisation consomme un minimum de cycles CPU en cours d'exécution, et son
    utilisation ne présente de ce fait aucun problème. La source utilisée pour
    déclencher le PRNG contient la date courante, l'identifiant du processus
    courant et un extrait de 128 octets aléatoirement choisi dans la pile. Ceci
    présente un inconvénient car le caractère aléatoire de cette source n'est
    pas vraiment fort, et au démarrage (lorsque la structure d'échanges n'est
    pas encore disponible), cette source ne produit que quelques octets
    d'entropie.  Vous devez donc toujours utiliser une source de déclenchement
    additionnelle, au moins pour le démarrage.
      • 

    • file:/chemin/vers/source
    
      
    Cette variante utilise un fichier externe
    file:/chemin/vers/source comme source de déclenchement
    du PRNG. Lorsque nombre est spécifié, seuls les
    nombre premiers octets du fichier forment l'entropie (et
    nombre est fourni comme premier argument à
    /chemin/vers/source). Lorsque nombre n'est pas
    spécifié, l'ensemble du fichier forme l'entropie (et 0
    est fourni comme premier argument à
    /chemin/vers/source). Utilisez cette source en
    particulier au démarrage, par exemple avec un fichier de
    périphérique /dev/random et/ou
    /dev/urandom (qui sont en général présent sur les
    plate-formes dérivées d'Unix modernes comme FreeBSD et Linux).
      
    
      Soyez cependant prudent : en général,
    /dev/random ne fournit que l'entropie dont il dispose
    réellement ; en d'autres termes, lorsque vous demandez 512 octets
    d'entropie, si le périphérique ne dispose que de 100 octets, deux
    choses peuvent se produire : sur certaines plates-formes, vous ne
    recevez que les 100 octets, alors que sur d'autres, la lecture se
    bloque jusqu'à ce qu'un nombre suffisant d'octets soit disponible
    (ce qui peut prendre beaucoup de temps). Il est préférable ici
    d'utiliser le périphérique /dev/urandom, car il ne se
    bloque jamais et fournit vraiment la quantité de données demandées.
    Comme inconvénient, les données reçues ne sont pas forcément de la
    meilleure qualité.
      • 


    • exec:/chemin/vers/programme
    
      
    Cette variante utilise un exécutable externe
    /chemin/vers/programme comme source de déclenchement du
    PRNG. Lorsque nombre est spécifié, seules les
    nombre premiers octets de son flux stdout
    forment l'entropie. Lorsque nombre n'est pas spécifié,
    l'intégralité des données produites sur stdout forment
    l'entropie. N'utilisez cette variante qu'au démarrage où une source
    de déclenchement fortement aléatoire est nécessaire, en utilisant
    un programme externe (comme dans l'exemple
    ci-dessous avec l'utilitaire truerand basé sur la
    bibliothèque truerand de AT&T que vous trouverez
    dans la distribution de mod_ssl). Bien entendu, l'utilisation de
    cette variante dans un contexte "connection" ralentit le serveur de
    manière trop importante, et en général, vous devez donc éviter
    d'utiliser des programmes externes dans ce contexte.
      • 

    • egd:/chemin/vers/socket-egd (Unix seulement)
    
      Cette variante utilise le socket de domaine Unix du Démon
    Générateur d'Entropie externe ou Entropy Gathering Daemon ou EGD
    (voir http://www.lothar.com/tech
    /crypto/) pour déclencher le PRNG. N'utilisez cette variante que
    si votre plate-forme ne possède pas de périphérique random ou
    urandom.
      • 

    

    Exemple
    SSLRandomSeed startup builtin
SSLRandomSeed startup "file:/dev/random"
SSLRandomSeed startup "file:/dev/urandom" 1024
SSLRandomSeed startup "exec:/usr/local/bin/truerand" 16
SSLRandomSeed connect builtin
SSLRandomSeed connect "file:/dev/random"
SSLRandomSeed connect "file:/dev/urandom" 1024

    Module:mod_ssl
    

    


    Si une renégociation SSL est requise dans un contexte de répertoire,
par exemple avec l'utilisation de SSLVerifyClient dans un bloc Directory ou
Location, mod_ssl doit mettre en tampon en mémoire tout corps de requête
HTTP en attendant qu'une nouvelle initialisation de connexion SSL puisse
être effectuée. Cette directive permet de définir la quantité de mémoire
à allouer pour ce tampon.
    


    
Notez que dans de nombreuses configurations, le client qui envoie un
corps de requête n'est pas forcément digne de confiance, et l'on doit
par conséquent prendre en considération la possibilité d'une attaque de
type déni de service lorsqu'on modifie la valeur de cette directive.

    Statut:Extension
    

    Module:mod_ssl
    

    

    SSLRequire est obsolète
    

    SSLRequire est obsolète et doit en général être
remplacée par l'expression Require. La syntaxe ap_expr de l'expression Require est
une extension de la syntaxe de SSLRequire, avec les
différences suivantes :
    


    Avec SSLRequire, les opérateurs de comparaison
<, <=, ... sont strictement équivalents
aux opérateurs lt, le, ... , et fonctionnent
selon une méthode qui compare tout d'abord la longueur des deux chaînes,
puis l'ordre alphabétique. Les expressions ap_expr, quant à elles, possèdent deux jeux
d'opérateurs de comparaison : les opérateurs <,
<=, ... effectuent une comparaison alphabétique de
chaînes, alors que les opérateurs -lt, -le,
... effectuent une comparaison d'entiers. Ces derniers possèdent aussi
des alias sans tiret initial : lt, le, ...

    


    


    Cette directive permet de spécifier une condition générale d'accès
qui doit être entièrement satisfaite pour que l'accès soit autorisé.
C'est une directive très puissante, car la condition d'accès spécifiée
est une expression booléenne complexe et arbitraire contenant un nombre
quelconque de vérifications quant aux autorisations d'accès.
    

    
L'expression doit respecter la syntaxe suivante (fournie ici
sous la forme d'une notation dans le style de la grammaire BNF) :
    

    

    expr     ::= "true" | "false"
           | "!" expr
           | expr "&&" expr
           | expr "||" expr
           | "(" expr ")"
           | comp

comp     ::= word "==" word | word "eq" word
           | word "!=" word | word "ne" word
           | word "<"  word | word "lt" word
           | word "<=" word | word "le" word
           | word ">"  word | word "gt" word
           | word ">=" word | word "ge" word
           | word "in" "{" wordlist "}"
           | word "in" "PeerExtList(" word ")"
           | word "=~" regex
           | word "!~" regex

wordlist ::= word
           | wordlist "," word

word     ::= digit
           | cstring
           | variable
           | function

digit    ::= [0-9]+
cstring  ::= "..."
variable ::= "%{" varname "}"
function ::= funcname "(" funcargs ")"
    

    

    Pour varname, toute variable décrite dans Variables d'environnement pourra être utilisée.
Pour funcname, vous trouverez la liste des fonctions
disponibles dans la documentation
ap_expr.
    


    expression est interprétée et traduite
sous une forme machine interne lors du chargement de la configuration,
puis évaluée lors du traitement de la requête. Dans le contexte des
fichiers .htaccess, expression est interprétée et exécutée
chaque fois que le fichier .htaccess intervient lors du traitement de la
requête.
    

    Exemple
    SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)-/                   \
            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd."          \
            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"}    \
            and %{TIME_WDAY} -ge 1 and %{TIME_WDAY} -le 5          \
            and %{TIME_HOUR} -ge 8 and %{TIME_HOUR} -le 20       ) \
           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
    

    



    La fonction PeerExtList(identifiant objet)
recherche une instance d'extension de certificat X.509 identifiée par
identifiant objet (OID) dans le certificat client. L'expression est
évaluée à true si la partie gauche de la chaîne correspond exactement à
la valeur d'une extension identifiée par cet OID (Si plusieurs
extensions possèdent le même OID, l'une d'entre elles au moins doit
correspondre).

    


    Exemple
    SSLRequire "foobar" in PeerExtList("1.2.3.4.5.6")
    

    


    Notes à propos de la fonction PeerExtList
    


      


    • L'identifiant objet peut être spécifié soit comme un nom
descriptif reconnu par la bibliothèque SSL, tel que
"nsComment", soit comme un OID numérique tel que
"1.2.3.4.5.6".
      • 


    • Les expressions contenant des types connus de la bibliothèque
SSL sont transformées en chaînes avant comparaison. Pour les extensions
contenant un type non connu de la bibliothèque SSL, mod_ssl va essayer
d'interpréter la valeur s'il s'agit d'un des types ASN.1 primaires UTF8String,
IA5String, VisibleString, ou BMPString. Si l'extension correspond à un
de ces types, la chaîne sera convertie en UTF-8 si nécessaire, puis
comparée avec la partie gauche de l'expression.

    Statut:Extension
    

    Module:mod_ssl
    

    

    
Cette directive permet de configurer le type de stockage du cache de
session SSL global et inter-processus. Ce cache est une fonctionnalité
optionnelle qui accélère le traitement parallèle des requêtes. Pour ce
qui est des requêtes vers un même processus du serveur (via HTTP
keep-alive), OpenSSL met en cache les informations de session SSL en
interne. Mais comme les clients modernes demandent des images en ligne
et d'autres données via des requêtes parallèles (un nombre de quatre
requêtes parallèles est courant), ces requêtes vont être servies par
plusieurs processus du serveur pré-déclenchés. Ici, un cache
inter-processus permet d'éviter des négociations de session
inutiles.
    

    
Les quatre types de stockage suivants sont actuellement
supportés :
    

      

    • none

    
      Cette valeur désactive le cache de session global et
    inter-processus, ce qui va ralentir le serveur de manière sensible
    et peut poser problème avec certains navigateurs, en particulier si
    les certificats clients sont activés. Cette configuration n'est pas
    recommandée.
      • 


    • nonenotnull

    
      Cette valeur désactive tout cache de session global et
    inter-processus. Cependant, elle force OpenSSL à envoyer un
    identifiant de session non nul afin de s'adapter aux clients bogués
    qui en nécessitent un.
      • 


    • dbm:/chemin/vers/fichier-données

    
      Cette valeur utilise un fichier de hashage DBM sur disque local
    pour synchroniser les caches OpenSSL locaux en mémoire des processus
    du serveur. Ce cache de session peut être sujet à des problèmes de
    fiabilité sous forte charge. Pour l'utiliser, le module
    mod_socache_dbm doit être chargé.
      • 


    • shmcb:/chemin/vers/fichier-données[(nombre)]

    
      Cette valeur utilise un tampon cyclique à hautes performances
    (d'une taille d'environ nombre octets) dans un segment de
    mémoire partagée en RAM (établi via
    /chemin/vers/fichier-données, pour synchroniser les
    caches OpenSSL locaux en mémoire des processus du serveur. C'est le
    type de cache de session recommandé. Pour l'utiliser, le module
    mod_socache_shmcb doit être chargé.
      • 


    • dc:UNIX:/chemin/vers/socket

    
      Cette valeur utilise les bibliothèques de mise en cache de
    sessions distribuée sur distcache.
    L'argument doit spécifier le serveur ou mandataire à utiliser en
    utilisant la syntaxe d'adressage distcache ; par exemple,
    UNIX:/chemin/vers/socket spécifie une socket de domaine
    Unix (en général un mandataire de dc_client local) ;
    IP:serveur.example.com:9001 spécifie une adresse IP.
    Pour l'utiliser, le module mod_socache_dc doit être
    chargé.

    SSLSessionCache "dbm:/usr/local/apache/logs/ssl_gcache_data"
SSLSessionCache "shmcb:/usr/local/apache/logs/ssl_gcache_data(512000)"

de session afin d'éviter toute corruption. Ce mutex peut être configuré
via la directive Mutex.

    Compatibilité:Disponible depuis la version 2.4.0 du serveur HTTP

    Cette directive permet de définir une clé secrète pour le chiffrement
et le déchiffrement des tickets de session TLS selon les préconisations
de la RFC 5077. Elle a
été conçue à l'origine pour les environnements de clusters où les
données des sessions TLS doivent être partagées entre plusieurs noeuds.
Pour les configurations ne comportant qu'une seule instance de httpd, il
est préférable d'utiliser les clés (aléatoires) générées par mod_ssl au
démarrage du serveur.
    

    Le fichier doit contenir 48 octets de données aléatoires créées de
préférence par une source à haute entropie. Sur un système de type UNIX,
il est possible de créer le fichier contenant la clé de la manière
suivante :
    


    
dd if=/dev/random of=/chemin/vers/fichier.tkey bs=1 count=48

    


    Ces clés doivent être renouvelées fréquemment, car il s'agit du seul
moyen d'invalider un ticket de session existant - OpenSSL ne permet pas
actuellement de spécifier une limite à la durée de
vie des tickets. Une nouvelle clé ne peut être utilisée qu'après avoir
redémarré le serveur. Tous les tickets de session existants deviennent
invalides après le redémarrage du serveur.

par des permissions similaires à celles du fichier spécifié par la
directive SSLCertificateKeyFile.

Apache, sous réserve d'utiliser OpenSSL version 0.9.8f ou supérieure.

    

    

    Cette directive permet d'activer ou de désactiver l'utilisation des
tickets de session TLS (RFC 5077).
    

    

    Les tickets de session TLS sont activés par défaut. Les utiliser sans
redémarrer le serveur selon une périodicité appropriée (par exemple
quotidiennement) compromet cependant le niveau de confidentialité.

Cette directive permet de contrôler l'accès des clients non-SNI à un serveur
virtuel à base de nom. Si elle est définie à on dans le
serveur virtuel à base de nom par défaut, les
clients non-SNI ne seront autorisés à accéder à aucun serveur virtuel
appartenant à cette combinaison IP/port. Par
contre, si elle est définie à on dans un serveur virtuel
quelconque, les clients non-SNI ne se verront interdire l'accès qu'à ce
serveur.

    


    
Cette option n'est disponible que si httpd a été compilé avec une

    Module:mod_ssl
    

    Compatibilité:Disponible si on utilise OpenSSL version 0.9.8h ou supérieure
    

    

    Cette directive permet d'activer l'"Agrafage OCSP" (OCSP stapling)
selon la définition de l'extension TLS "Certificate Status Request"
fournie dans la RFC 6066. Si elle est activée et si le client le
demande, mod_ssl va inclure une réponse OCSP à propos de son propre
certificat dans la négociation TLS. Pour pouvoir activer l'Agrafage
OCSP, il est nécessaire de configurer un SSLStaplingCache.
    


    L'agrafage OCSP dispense le client de requérir le serveur OCSP
directement ; il faut cependant noter que selon les spécifications de la
RFC 6066, la réponse CertificateStatus du serveur ne peut
inclure une réponse OCSP que pour un seul certificat. Pour les
certificats de serveur comportant des certificats de CA intermédiaires
dans leur chaîne (c'est un cas typique de nos jours), l'implémentation
actuelle de l'agrafage OCSP n'atteint que partiellement l'objectif d'
"économie en questions/réponse et en ressources". Pour plus de détails,
voir la RFC 6961 (TLS
Multiple Certificate Status Extension).

    


    Lorsque l'agrafage OCSP est activé, le mutex
ssl-stapling contrôle l'accès au cache de l'agrafage OCSP
afin de prévenir toute corruption, et le mutex
sss-stapling-refresh contrôle le raffraîchissement des
réponses OCSP. Ces mutex peuvent être configurés via la directive
Mutex.

Cette directive permet de définir le niveau de vérification du
certificat pour l'authentification du client. Notez que cette directive
peut être utilisée à la fois dans les contextes du serveur principal et
du répertoire. Dans le contexte du serveur principal, elle s'applique au
processus d'authentification du client utilisé au cours de la
négociation SSL standard lors de l'établissement d'une connexion. Dans
un contexte de répertoire, elle force une renégociation SSL avec le
niveau de vérification du client spécifié, après la lecture d'une
requête HTTP, mais avant l'envoi de la réponse HTTP.
    

    
Les valeurs de niveau disponibles sont les suivantes :
    

      

    • none:
     aucun certificat client n'est requis
      • 

    • optional:
     le client peut présenter un certificat valide
      • 

    • require:
     le client doit présenter un certificat valide
      • 

    • optional_no_ca:
     le client peut présenter un certificat valide, mais il n'est pas
     nécessaire que ce dernier soit vérifiable (avec succès). Cette option ne
     peut pas être utilisée lors de l'authentification du client.

    Module:mod_ssl
    

    

    
Cette directive permet de spécifier la profondeur maximale à laquelle
mod_ssl va effectuer sa vérification avant de décider que le client ne
possède pas de certificat valide. Notez que cette directive peut être
utilisée à la fois dans les contextes du serveur principal et de
répertoire. Dans le contexte du serveur principal, elle s'applique au
processus d'authentification du client utilisé au cours de la
négociation SSL standard lors de l'établissement d'une connexion. Dans
un contexte de répertoire, elle force une renégociation SSL avec le
client selon la nouvelle profondeur spécifiée, après la lecture d'une
requête HTTP, mais avant l'envoi de la réponse HTTP.
    

    
La profondeur correspond au nombre maximum de fournisseurs de
certificats intermédiaires, c'est à dire le nombre maximum de
certificats de CA que l'on est autorisé à suivre lors de la vérification
du certificat du client. Une profondeur de 0 signifie que seuls les
certificats clients auto-signés sont acceptés ; la profondeur par défaut
de 1 signifie que le certificat client peut être soit auto-signé, soit
signé par une CA connue directement du serveur (c'est à dire que le
certificat de la CA doit être référencé par la directive SSLCACertificatePath), etc...
    

    Exemple
    SSLVerifyDepth 10

    Sommaire
    

    
    Ce module permet d'utiliser l'authentification basique HTTP pour
    restreindre l'accès en recherchant les utilisateurs dans les
    fournisseurs d'authentification spécifiés. Il est en général
    combiné avec au moins un module d'authentification comme
    mod_authn_file et un module d'autorisation comme
    mod_authz_user. L'authentification HTTP à
    base de condensé (digest), quant à elle, est fournie par le module
    mod_auth_digest.

    Module:mod_auth_basic
    

    
    
    Normalement, chaque module d'autorisation énuméré dans la
    directive AuthBasicProvider va tenter de
    vérifier l'utilisateur, et si ce dernier n'est trouvé dans aucun des
    fournisseurs, l'accès sera refusé. Définir explicitement la
    directive AuthBasicAuthoritative à
    Off permet de confier l'autorisation et
    l'authentification à d'autres modules non basés sur les fournisseurs
    si aucun identifiant utilisateur ou aucune
    règle ne correspondent à l'identifiant utilisateur
    spécifié. Ceci ne peut s'avérer nécessaire que lorsque
    mod_auth_basic est combiné avec des modules tiers
    qui n'ont pas été configurés à l'aide de la directive AuthBasicProvider. Lorsqu'on
    utilise de tels modules, l'ordre dans lequel s'effectue le
    traitement est défini dans le code source des modules et n'est pas
    configurable.

    Statut:Base
    

    Module:mod_auth_basic
    

    Compatibilité:Disponible à partir de la version 2.4.5 du serveur HTTP
Apache
    

    
    
    Les nom d'utilisateur et mot de passe spécifiés sont rassemblés
    dans un en-tête d'autorisation qui est transmis au serveur ou au
    service sous-jacent au serveur. Ces nom d'utilisateur et mot de
    passe sont interprétés par l'interpréteur
    d'expression, ce qui permet de les définir en fonction de
    paramètres de la requête.
    

    
    Si aucun mot de passe n'est spécifié, la valeur par défaut
    "password" sera utilisée. Pour désactiver l'authentification de base
    simulée pour un espace d'URL, définissez AuthBasicFake à "off".
    

    
    Dans l'exemple suivant, un nom d'utilisateur et un mot de passe
    prédéfinis sont transmis à un serveur d'arrière-plan :
    

    
    Exemple de transmission d'un nom d'utilisateur et
    d'un mot de passe prédéfinis
    <Location "/demo">
    AuthBasicFake demo demopass
</Location>
    

    

    
    Dans l'exemple suivant, l'adresse email extraite d'un certificat
    client est transmise au serveur, étendant par là-même la
    fonctionnalité de l'option FakeBasicAuth de la directive SSLOptions. Comme avec l'option
    FakeBasicAuth, le mot de passe se voit attribué le contenu fixe de
    la chaîne "password".
    

    
    Exemple d'utilisation avec un certificat
    <Location "/secure">
    AuthBasicFake "%{SSL_CLIENT_S_DN_Email}"
</Location>
    

    

    
    Pour compléter l'exemple précédent, il est possible de générer la
    valeur du mot de passe en procédant à un hashage de l'adresse email
    à partir d'un mot d'une passphrase initial fixée, puis de transmettre le
    résultat obtenu au serveur d'arrière-plan. Ceci peut s'avérer utile
    pour donner accès à des serveurs anciens qui ne supportent pas les
    certificats clients.
    

    
    Exemple de génération de mot de passe par hashage de
    l'adresse email
    <Location "/secure">
    AuthBasicFake "%{SSL_CLIENT_S_DN_Email}" "%{sha1:passphrase-%{SSL_CLIENT_S_DN_Email}}"
</Location>

    La directive AuthBasicProvider permet de
    définir le fournisseur utilisé pour authentifier les utilisateurs
    pour la zone du site web concernée. Le fournisseur par défaut
    file est implémenté par le module
    mod_authn_file. Assurez-vous que le module
    implémentant le fournisseur choisi soit bien présent dans le
    serveur.
    

    
    Exemple
    <Location "/secure">
    AuthType basic
    AuthName "private area"
    AuthBasicProvider  dbm
    AuthDBMType        SDBM
    AuthDBMUserFile    "/www/etc/dbmpasswd"
    Require            valid-user
</Location>
    

    
    
    Les fournisseurs sont sollicités dans l'ordre jusqu'à ce que l'un
    d'entre eux trouve une correspondance pour le nom d'utilisateur de
    la requête ; alors, ce dernier fournisseur sera le seul à vérifier
    le mot de passe. Un échec dans la vérification du mot de passe
    n'entraîne pas le passage du contrôle au fournisseur suivant.
    

    
    Les différents fournisseurs disponibles sont implémentés par les
    modules mod_authn_dbm,
    mod_authn_file, mod_authn_dbd,
    mod_authnz_ldap et mod_authn_socache.

    Directive AuthBasicUseDigestAlgorithm
    

    

    Description:Vérifie les mots de passe auprès des fournisseurs
d'authentification à la manière de l'authentification de type Digest.

    

    Syntaxe:AuthBasicUseDigestAlgorithm MD5|Off
    

    Défaut:AuthBasicUseDigestAlgorithm Off
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Base
    

    Module:mod_auth_basic
    

    Compatibilité:Disponible à partir de la version 2.4.7 du serveur HTTP
Apache
    

    
    
    Normalement, lorsqu'on utilise l'authentification basique, les
    fournisseurs spécifiés via la directive AuthBasicProvider tentent de
    contrôler l'identité d'un utilisateur en recherchant dans leurs
    bases de données l'existence d'un couple utilisateur/mot de passe
    correspondant. Les mots de passe enregistrés sont en général
    chiffrés, mais ce n'est pas systématique ; chaque fournisseur peut
    choisir son propre mode de stockage des mots de passe.
    

    
    Lorsqu'on utilise l'authentification de type Digest, les
    fournisseurs spécifiés par la directive AuthDigestProvider effectuent
    une recherche similaire dans leurs bases de
    données pour trouver un couple utilisateur/mot de passe
    correspondant. Cependant, à la différence de l'authentification
    basique, les données associées à chaque utilisateur et comportant le
    nom d'utilisateur, le domaine de protection (realm) et le mot de
    passe doivent être contenues dans une chaîne chiffrée (Voir le
    document RFC 2617,
    Section 3.2.2.2 pour plus de détails à propos du type de
    chiffrement utilisé pour cette chaîne).
    

    
    A cause de la différence entre les méthodes de stockage des
    données des authentifications de type basique et digest, le passage
    d'une méthode d'authentification de type digest à une méthode
    d'authentification de type basique requiert l'attribution de
    nouveaux
    mots de passe à chaque utilisateur, car leur mots de passe existant
    ne peut pas être extrait à partir du schéma de stockage utilisé
    par les fournisseurs d'authentification de type digest.
    

    
    Si la directive AuthBasicUseDigestAlgorithm est
    définie à la valeur MD5, le mot de passe d'un
    utilisateur dans le cas de l'authentification basique sera vérifié
    en utilisant le même format de chiffrement que dans le cas de
    l'authentification de type digest. Tout d'abord, une chaîne
    comportant le nom d'utilisateur, le domaine de protection (realm) et
    le mot de passe est générée sous forme de condensé (hash) en
    utilisant l'algorithme MD5 ; puis le nom d'utilisateur et cette
    chaîne chiffrée sont transmis aux fournisseurs spécifiés via la
    directive AuthBasicProvider comme si la
    directive AuthType
    était définie à Digest et si l'authentification de type
    Digest était utilisée.
    
    

    
    Grâce à cette directive, un site peut basculer d'une
    authentification de type digest à basique sans devoir changer les
    mots de passe des utilisateurs. 
    

    
    
      Le processus inverse consistant à passer d'une authentification de
      type basique à digest sans changer les mots de passe n'est en
      général pas possible. Les mots de passe enregistrés dans le cas
      d'une authentification de type basique ne pourront être extraits
      et chiffrés à nouveau selon le schéma de l'authentification de
      type digest, que s'ils ont été stockés en clair ou selon un schéma de
      chiffrement réversible.
    
    

    
    
      Seuls les fournisseurs qui supportent l'authentification de type
      digest pourront authentifier les utilisateurs lorsque la directive
      AuthBasicUseDigestAlgorithm
      est définie à MD5. L'utilisation d'un autre
      fournisseur provoquera un message d'erreur et le client se verra
      refuser l'accès.

    Module Apache mod_dir
    

    

    Langues Disponibles:  en  |

 tr 
    

    

    Description:Permet la redirection des adresses se terminant par un
répertoire sans slash de fin et la mise à disposition des fichiers index
de répertoire
    

    Statut:Base
    

    Identificateur de Module:dir_module
    

    Fichier Source:mod_dir.c
    

    Sommaire
    

    
    L'index d'un répertoire peut provenir de deux sources :
    

    
      
      
    • Un fichier écrit par l'utilisateur, dont le nom, en général
      appelé index.html, peut être défini à l'aide de la
      directive DirectoryIndex
      fournie par le module mod_dir.
      • 

      
    • Un listing généré par le serveur, par l'intermédiaire du
      module mod_autoindex.
      • 
    
    
    
    Les deux fonctions sont bien distinctes, si bien que vous pouvez
    supprimer (ou remplacer) la génération automatique d'index, si vous
    le souhaitez.
    

    
    Une redirection "slash de fin" est effectuée lorsque le serveur
    reçoit une requête pour une URL du style
    http://nom-serveur/foo/nom-rep où nom-rep
    est le nom d'un répertoire. Comme les répertoires nécessitent un slash de
    fin, mod_dir effectue une redirection vers
    http://nom-serveur/foo/nom-rep/.

    Directive DirectoryCheckHandler
    

    

    Description:Définit la réponse de ce module lorsqu'un autre
gestionnaire est utilisé
    

    Syntaxe:DirectoryCheckHandler On|Off
    

    Défaut:DirectoryCheckHandler Off
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_dir
    

    Compatibilité:Disponible depuis la version 2.4.8 du serveur HTTP
Apache. Les versions antérieures à 2.4 se comportaient implicitement
comme si "DirectoryCheckHandler ON" avait été spécifié.
    

    
    
    La directive DirectoryCheckHandler permet
    de faire en sorte que mod_dir recherche un index
    de répertoire ou ajoute des slashes de fin lorsqu'un autre
    gestionnaire à été défini pour l'URL considérée. Les gestionnaires
    peuvent être définis à via des directives telles que
    SetHandler ou par d'autres
    modules tels que mod_rewrite au cours des
    substitutions de niveau répertoire.
    

    
    Dans les versions antérieures à 2.4, ce module ne modifiait pas son
    comportement si un autre gestionnaire avait été défini pour l'URL
    considérée. Ceci permettait de servir des index de répertoires même si une
    directive SetHandler avait été définie pour un
    répertoire entier, mais pouvait aussi être à l'origine de conflits avec
    d'autres modules comme mod_rewrite.

    Directive DirectoryIndex
    

    

    Description:Liste des fichiers ressources à rechercher lorsque le
client envoie une requête pour un répertoire
    

    Syntaxe:DirectoryIndex
    disabled | url locale [url locale] ...
    

    Défaut:DirectoryIndex index.html
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_dir
    

    
    
    La directive DirectoryIndex permet de
    définir une liste de fichiers ressources à rechercher lorsqu'un
    client envoie une requête pour l'index d'un répertoire, en ajoutant
    un '/' à la fin du nom de ce dernier. url locale est
    l'URL (codée avec caractères '%') d'un document du serveur, relative
    au répertoire faisant l'objet de la requête ; il s'agit en général
    du nom d'un fichier situé dans le répertoire. Si plusieurs URLs sont
    fournies, le serveur renverra la première d'entre elles qui
    correspond à une ressource existante. Si aucune ressource ne
    correspond à la liste des URLs spécifiées, et si l'option
    Indexes est définie, le serveur générera son propre
    listing du répertoire.
    

    
    Exemple
    DirectoryIndex index.html
    

    

    
    Avec cette configuration, une requête pour l'URL
    http://example.com/docs/ renverrait au client la
    ressource http://example.com/docs/index.html si elle
    existe, ou provoquerait la génération du listing du répertoire si la
    ressource n'existe pas.
    

    
    Notez qu'il n'est pas nécessaire que les documents soient
    relatifs au répertoire ;
    

    
    DirectoryIndex index.html index.txt  /cgi-bin/index.pl
    


    
    provoquerait l'exécution du script CGI
    /cgi-bin/index.pl si aucun des fichiers
    index.html ou index.txt n'existe dans le
    répertoire considéré.
    

    
    La spécification du seul argument "disabled" empêche
    mod_dir de rechercher un index. Un argument
    "disabled" sera interprété de manière littérale si d'autres
    arguments sont présents avant ou après lui, même s'ils sont
    eux-mêmes des arguments "disabled".
    

    
    Note: Positionner plusieurs directives DirectoryIndex
    au coeur du même context complète la liste des ressources et ne l'écrase pas :
    
    
    
    # Exemple A: Positionner index.html en page d'index, puis ajouter index.php.
<Directory "/foo">
    DirectoryIndex index.html
    DirectoryIndex index.php
</Directory>

# Exemple B: La même chose que l'exemple A, mais réalisé au moyen d'une seule directive.
<Directory "/foo">
    DirectoryIndex index.html index.php
</Directory>

# Exemple C: Pour remplacer la liste des ressources, il faut d'abord la vider :
# Ici, seul index.php restera référencé comme ressource d'index.
<Directory "/foo">
    DirectoryIndex index.html
    DirectoryIndex disabled
    DirectoryIndex index.php
</Directory>

    Directive DirectoryIndexRedirect
    

    

    Description:Définit une redirection externe pour les index de
répertoires.

    

    Syntaxe:DirectoryIndexRedirect on | off | permanent | temp | seeother |
3xx-code

    

    Défaut:DirectoryIndexRedirect off
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_dir
    

    Compatibilité:Disponible depuis la version 2.3.14
    

    
    
    Par défaut, c'est la page définie par la directive
    DirectoryIndex qui est sélectionnée et
    renvoyée de manière transparente au client. La directive
    DirectoryIndexRedirect permet de rediriger le
    client via une redirection de type 3xx.
    

    
    Les arguments acceptés sont :
    
    
      
     
    • on : envoie une redirection 302 vers l'index choisi.
      • 
     
    • off : n'envoie aucune redirection. Il s'agit du comportement historique de mod_dir.
      • 
     
    • permanent : envoie une redirection 301 (permanent) vers l'index choisi.
      • 
     
    • temp : ceci est équivalent à on
      • 
     
    • seeother : envoie une redirection 303 (également appelée "See Other") vers l'index choisi.
      • 
     
    • 3xx-code : envoie une redirection accompagnée du code 3xx choisi.
      • 
    
    



    
    Exemple
    DirectoryIndexRedirect on
    

    

    
    Une requête pour http://example.com/docs/ se
    solderait par une redirection temporaire vers
    http://example.com/docs/index.html si cette ressource
    existe.

    Directive DirectorySlash
    

    

    Description:Activation/Désactivation de la redirection "slash de
fin"
    

    Syntaxe:DirectorySlash On|Off
    

    Défaut:DirectorySlash On
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_dir
    

    
    
    La directive DirectorySlash permet de
    déterminer si mod_dir doit corriger ou non les URLs
    pointant vers un répertoire.
    

    
    En général, si un utilisateur envoie une requête pour une
    ressource sans slash de fin, cette ressource représentant un
    répertoire, mod_dir le redirige vers la même
    ressource, mais en ajoutant un slash de fin, et ceci pour
    plusieurs bonnes raisons :
    

    
      
    
    • La requête de l'utilisateur contiendra finalement l'URL
    canonique de la ressource
      • 
    
    • mod_autoindex fonctionnera correctement. Comme
    il n'indique pas le chemin dans le lien, le chemin de l'URL serait
    incorrect.
      • 
    
    • La directive DirectoryIndex n'est évaluée
    que pour les répertoires se terminant par un slash.
      • 
    
    • Les références à des URLs relatives dans les pages html
    fonctionneront alors correctement.
      • 
    
    

    
    Si vous ne souhaitez pas voir ces effets, et si
    les raisons évoquées ci-dessus ne s'appliquent pas à vous, vous
    pouvez désactiver la redirection comme indiqué ci-dessous.
    Gardez cependant à l'esprit que ceci peut avoir des répercutions en
    matière de sécurité.
    

    
    # voir l'avertissement de sécurité ci-dessous !
<Location "/some/path">
    DirectorySlash Off
    SetHandler some-handler
</Location>
    


    
    Avertissement de sécurité
    
    
    La désactivation de la redirection "slash de fin" peut entraîner
    la divulgation d'informations. Considérons la situation où
    mod_autoindex est actif (Options
    +Indexes), où la directive DirectoryIndex a pour valeur une ressource valide (par
    exemple index.html), et où aucun gestionnaire
    particulier n'a été défini pour cette URL. Dans ce cas, une requête
    avec slash de fin afficherait le contenu du fichier
    index.html ; par contre, une requête sans slash
    de fin afficherait un listing du contenu du
    répertoire.
    
    
    
    
    Notez aussi que certains navigateurs peuvent modifier par erreur
    des requêtes POST en requêtes GET lors d'une redirection, les
    données POST étant alors perdues.

    Directive FallbackResource
    

    

    Description:Définit une URL par défaut pour les requêtes qui ne ciblent
aucun fichier
    

    Syntaxe:FallbackResource disabled | url-locale
    

    Défaut:disabled - httpd renvoie un code d'erreur 404 (Not Found)
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Base
    

    Module:mod_dir
    

    Compatibilité:L'argument disabled est disponible à partir
de la version 2.4.4 du serveur HTTP Apache.
    

    
    
    Cette directive permet de définir un traitement pour toute URL
    qui ne correspond à aucune ressource de votre système de fichiers,
    et qui provoquerait sans cela l'envoi d'un code d'erreur HTTP 404
    (Not Found).
    Par exemple
    
    
    FallbackResource /not-404.php
    

    
    fait en sorte que les requêtes ne correspondant à aucun fichier
    soient traitées par non-404.php, sans affecter les
    requêtes pour des fichiers existants.
    
    
    Il est souvent souhaitable qu'un seul fichier ou ressource traite
    toutes les requêtes à destination d'un répertoire
    particulier, sauf pour les requêtes qui correspondent à un fichier
    ou script existant. On y fait souvent référence sous le terme
    'contrôleur frontal'.
    
    
    Dans les versions plus anciennes de httpd, cet effet nécessitait
    en général mod_rewrite, et l'utilisation des tests
    conditionnels -f et -d pour vérifier
    l'existence des fichiers et répertoires. Maintenant, une seule ligne
    de configuration est nécessaire.
    
    
    FallbackResource /index.php
    

    
    Les fichiers existants comme des images, des fichiers css, etc...
    seront traités normalement.
    
    
    L'argument disabled permet de désactiver cette
    fonctionnalité dans le cas où l'héritage d'un répertoire parent
    n'est pas souhaité.
    
    
    Pour un URI intermédiaire tel que
    http://example.com/blog/, cet URI intermédiaire doit être
    spécifié en tant que url-locale :
    
    
    <Directory "/web/example.com/htdocs/blog">
    FallbackResource /blog/index.php
</Directory>
<Directory "/web/example.com/htdocs/blog/images">
    FallbackResource disabled
</Directory>
    

    
    Un gestionnaire de ressource par défaut (dans l'exemple ci-dessus
    /blog/index.php) peut accéder à l'URL de la requête originale
    via la variable de serveur REQUEST_URI. Pour accéder à cette
    variable en PHP, par exemple, utilisez $_SERVER['REQUEST_URI'].

    Module Apache mod_proxy_hcheck
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Check up dynamique des membres du groupe de répartition de charge
(équipiers) pour mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_hcheck_module
    

    Fichier Source:mod_proxy_hcheck.c
    

    Compatibilité:Disponible à partir de la version 2.4.21 du serveur HTTP Apache
    

    Sommaire
    

    
    Ce module permet d'effectuer un check up dynamique des membres du groupe
    de répartition de charge (équipiers). Ce check up peut être activé pour un
    ou plusieurs équipiers et il est indépendant des requêtes de mandataire
    inverse proprement dites.
    

    
    Pour fonctionner, ce module nécessite le chargement préalable de
    mod_watchdog.
    


    Paramètres
    
  
    Le mécanisme de check up est activé via l'utilisation de paramètres
  supplémentaires de la directive BalancerMember configurés de manière standard
  via la directive ProxyPass :
    

  
    Ce module définit un nouveau drapeau d'état status pour BalancerMember :
  "C". Lorsque l'équipier est mis hors service suite à un
  disfonctionnement déterminé par le module de check up, ce drapeau est activé
  et peut être lu (et modifié) via le balancer-manager.

    Exemples d'utilisation
    

	
    
    L'exemple suivant montre comment configurer le check up pour différents
    serveurs d'arrière-plan :
    

	
	
    ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyHCExpr gdown {%{REQUEST_STATUS} =~ /^[5]/}
ProxyHCExpr in_maint {hc('body') !~ /Under maintenance/}

<Proxy balancer://foo>
  BalancerMember http://www.example.com/  hcmethod=GET hcexpr=in_maint hcuri=/status.php
  BalancerMember http://www2.example.com/ hcmethod=HEAD hcexpr=ok234 hcinterval=10
  BalancerMember http://www3.example.com/ hcmethod=TCP hcinterval=5 hcpasses=2 hcfails=3
  BalancerMember http://www4.example.com/
</Proxy>

ProxyPass "/" "balancer://foo"
ProxyPassReverse "/" "balancer://foo"
    



    Dans ce scénario, on teste l'équipier http://www.example.com/ en lui
envoyant une requête GET /status.php et en regardant si la réponse
contient la chaîne Under maintenance. Si c'est le cas, le check up est
considéré comme ayant échoué et l'équipier est mis hors service. Ce check up
dynamique est effectué toutes les 30 secondes, ce qui correspond à la valeur par
défaut.
    


    On teste l'équipier http://www2.example.com/ en lui envoyant
simplement une requête HEAD toutes les 10 secondes et en vérifiant
que la réponse HTTP est bien un code d'état de 2xx, 3xx ou 4xx. On teste
l'équipier http://www3.example.com/  en vérifiant simplement toutes
les 5 secondes que le socket vers ce serveur est bien opérationnel. Si ce
serveur est marqué "hors service", il lui faudra 2 check up réussis pour être
réactivé et participer à nouveau à la répartition de charge. Si à ce moment-là
il échoue à 3 check up successifs, il sera à nouveau mis hors service. Enfin,
l'équipier http://www4.example.com/ ne fait l'objet d'aucun check
up.

    Directive ProxyHCExpr
    

    

    Description:Crée et nomme une expression conditionnelle à utiliser pour
déterminer la santé d'un serveur d'arrière-plan en fonction de sa valeur
    

    Syntaxe:ProxyHCExpr name {ap_expr expression}
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy_hcheck
    

    
    
    La directive ProxyHCExpr permet de créer et nommer
    une expression conditionnelle dont la valeur calculée en fonction des
    en-têtes de la réponse du serveur d'arrière-plan permettra d'évaluer la
    santé de ce dernier. Cette expression nommée peut alors être assignée aux
    serveurs d'arrière-plan via le paramètre hcexpr.
    

    
    ProxyHCExpr: interprète les réponses 2xx/3xx/4xx comme des
    check up réussis
    ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyPass "/apps"     "balancer://foo"

<Proxy balancer://foo>
  BalancerMember http://www2.example.com/  hcmethod=HEAD hcexpr=ok234 hcinterval=10
</Proxy>
    

    

    
    
    L'expression peut utiliser des accolades ("{}")
    comme délimiteurs en plus des guillemets normaux.
    
    

    
    Si l'on utilise une méthode de check up (par exemple GET)
    qui génère un corps de réponse, ce corps peut lui-même être ausculté via
    ap_expr en utilisant la fonction associée aux expressions
    hc() spécifique à ce module.
    

    
    Dans l'exemple suivant, on envoie une requête GET au serveur
    d'arrière-plan, et si le corps de la réponse contient la chaîne Under
    maintenance, ce serveur d'arrière-plan est mis hors service.
    

    
    ProxyHCExpr: auscultation du corps de la réponse
    ProxyHCExpr in_maint {hc('body') !~ /Under maintenance/}
ProxyPass "/apps"     "balancer://foo"

<Proxy balancer://foo>
  BalancerMember http://www.example.com/ hcexpr=in_maint hcmethod=get hcuri=/status.php
</Proxy>
    

    

    
    NOTE: Comme le corps de la réponse peut être assez grand, il est
    recommandé de privilégier un check up basé sur les codes d'état.

    Si Apache httpd et APR ont été compilés avec le support des threads, le
    module de check up peut confier ce travail à un jeu de threads associé au
    processus Watchdog, ce qui permet l'exécution des check up en parallèle. La
    directive ProxyHCTPsize permet de déterminer la
    taille de ce jeu de threads. Une valeur de 0 signifie qu'aucun
    jeu de threads ne sera utilisé, et le check up des différents équipiers sera
    alors effectué séquentiellement.

    Description:Mise en cache mémoire d'une liste statique de
fichiers
    

    Statut:Expérimental
    

    Identificateur de Module:file_cache_module
    

    Fichier Source:mod_file_cache.c
    

    Sommaire
    


    
    
      Ce module doit être utilisé avec précautions. Il est recommandé de
      lire attentivement ce document, car l'utilisation de
      mod_file_cache peut facilement conduire à la
      création d'un site inopérant.
    
    

    
    La mise en cache de fichiers souvent demandés mais rarement
    modifiés est une technique permettant de réduire la charge du
    serveur. mod_file_cache met en oeuvre deux
    techniques de mise en cache de fichiers statiques
    fréquemment demandés. Des directives de configuration vous
    permettent d'indiquer à mod_file_cache soit
    d'ouvrir et de charger une image en mémoire d'un fichier avec
    mmap(), soit de préouvrir un fichier et de maintenir en
    service le gestionnaire du fichier. Les deux techniques
    permettent de réduire la charge du serveur lors du traitement des
    requêtes concernant ces fichiers, en accomplissant une partie du
    travail nécessaire à la mise à disposition de ces fichiers (en
    particulier les opérations d'entrées/sorties sur les fichiers) au
    démarrage du serveur, plutôt qu'au cours de chaque requête.
    

    
    Note : ces techniques sont inutilisables pour accélérer des
    programmes CGI ou d'autres fichiers servis par des gestionnaires de
    contenu spéciaux. Elles ne peuvent être utilisées que pour des
    fichiers standards, normalement servis par le gestionnaire de contenu
    de base d'Apache.
    

    
    Ce module est une extension du module
    d'Apache 1.3 mod_mmap_staticet s'en inspire
    fortement .
    

    


    top
    

    

    Utilisation de mod_file_cache
    

    
    mod_file_cache gère la mise en cache d'une liste
    de fichiers définie de manière statique via une des directives
    MMapFile ou
    CacheFile au niveau
    de la configuration du serveur principal.
    

    
    Les deux directives ne sont pas supportées par toutes les
    plates-formes. Par exemple, Apache pour Windows ne supporte pas
    actuellement la directive MMapFile, alors que d'autres
    plates-formes, comme AIX, supportent les deux. Vous recevrez un
    message d'erreur dans le journal des erreurs du serveur si vous
    essayez d'utiliser une directive non supportée. Si vous utilisez une
    directive non supportée, le serveur démarrera, mais les fichiers ne
    seront pas mis en cache. Sur les plates-formes qui supportent les
    deux directives, vous devez faire des essais afin de déterminer
    quelle directive vous convient le mieux.
    

    
    Directive MMapFile
    

      
    La directive MMapFile du module
      mod_file_cache permet de transférer en mémoire
      une liste statique de fichiers à l'aide de l'appel système
      mmap(). Cet appel système est disponible sur la
      plupart des plates-formes de style Unix, mais pas sur toutes. Il
      existe parfois des limites spécifiques au système quant à la
      taille et au nombre de fichiers qui peuvent être
      mmap()és, et l'expérimentation est probablement la
      méthode la plus simple pour déterminer ces limites.
    

      
    Ce mmap()age n'est effectué qu'une seul fois au
      démarrage ou redémarrage du serveur. Ainsi, chaque fois qu'un des
      fichiers chargés en mémoire est modifié au niveau du système de
      fichiers, vous devez redémarrer le serveur (voir la
      documentation sur l'Arrêt et redémarrage). Pour bien
      insister sur ce point, si des fichiers sont modifiés sur
      disque, et si vous ne redémarrez pas le serveur, vous allez
      finir par servir des contenus complètement obsolètes. Vous devez
      mettre à jour les fichiers en renommant l'ancienne version et en
      enregistrant la nouvelle sur disque. Pour y parvenir, on peut
      utiliser des outils comme rdist et mv.
      La raison pour laquelle ce module ne prend pas en compte les
      modifications de fichiers réside dans le fait que cette
      vérification nécessiterait un appel à stat() à chaque
      accès, et en fin de compte, l'augmentation de la consommation de
      ressources finirait par aller contre le but initial de
      réduire les entrées/sorties.
    
    

    
    Directive CacheFile
    

      
    La directive CacheFile du module
      mod_file_cache permet d'associer un
      gestionnaire ou descripteur de fichier à chaque
      fichier énuméré dans la directive de configuration et place ces
      gestionnaires de fichiers ouverts dans le cache. Lorsqu'un des
      fichier est demandé, le serveur sélectionne son gestionnaire dans
      le cache et le transmet à l'API sendfile() (ou
      TransmitFile() sous Windows).
    

      

      
    Cette mise en cache des gestionnaire n'est effectuée qu'une
      seule fois au démarrage ou redémarrage du système. Ainsi, chaque
      fois qu'un des fichiers chargés en mémoire est modifié au niveau
      du système de fichiers, vous devez redémarrer le serveur
      (voir la documentation sur l'Arrêt et redémarrage).
      Pour bien
      insister sur ce point, si des fichiers sont modifiés sur
      disque, et si vous ne redémarrez pas le serveur, vous allez
      finir par servir des contenus complètement obsolètes. Vous devez
      mettre à jour les fichiers en renommant l'ancienne version et en
      enregistrant la nouvelle sur disque. Pour y parvenir, on peut
      utiliser des outils comme rdist et
      mv.
    
    

    
    Note
    
      
    Ne cherchez pas à trouver de directive qui met tous les
      fichiers d'un répertoire en cache, de manière récursive. Pour y
      parvenir, vous pouvez vous reporter à la directive Include directive, et considérer cette
      commande :
    

      
    
        find /www/htdocs -type f -print \
    
        | sed -e 's/.*/mmapfile &/' > /www/conf/mmap.conf

    Directive CacheFile
    

    

    Description:Met en cache une liste de gestionnaires de fichiers au
démarrage
    

    Syntaxe:CacheFile chemin fichier [chemin fichier] ...
    

    Contexte:configuration globale
    

    Statut:Expérimental
    

    Module:mod_file_cache
    

    
    
    La directive CacheFile permet d'associer
    des gestionnaires à un ou plusieurs fichiers (séparés par des
    espaces), et de placer ceux-ci dans le cache au démarrage du
    serveur. Les gestionnaires des fichiers mis en cache sont
    automatiquement fermés à l'arrêt du serveur. Lorsqu'un ou plusieurs
    fichiers ont été modifiés sur disque, le serveur doit être redémarré
    afin que les modifications soient prises en compte par le cache.
    

    
    Soyez prudent avec les arguments chemin fichier : ils
    doivent correspondre exactement au chemin du système de fichier que
    créent les gestionnaires de traduction URL-vers-nom-fichier
    d'Apache. On ne peut pas comparer des inodes ou autres identifiants
    pour mettre en correspondance des chemins à l'aide de liens
    symboliques (etc...), car là encore, ceci nécessiterait un
    appel à stat() supplémentaire, ce qui n'est pas acceptable.
    Il n'est pas garanti que ce module fonctionne avec des noms de
    fichiers réécrits par mod_alias ou
    mod_rewrite.

    CacheFile /usr/local/apache/htdocs/index.html

    Statut:Expérimental
    

    Module:mod_file_cache
    

    
    
    La directive MMapFile permet de charger un
    ou plusieurs fichiers (séparés par des espaces) en mémoire au
    démarrage du serveur. Ceux-ci sont automatiquement déchargés de la
    mémoire à l'arrêt du serveur. Lorsqu'un ou plusieurs fichiers ont
    été modifiés sur disque, on doit au minimum envoyer un signal
    HUP ou USR1 au serveur afin de les
    remmap()er.
    

    
    Soyez prudent avec les arguments chemin fichier : ils
    doivent correspondre exactement au chemin du système de fichier que

    Apache Module mod_cache_disk
    

    

    Available Languages:  en  |

    Description:Disk based storage module for the HTTP caching filter.
    

    Status:Extension
    

    Module Identifier:cache_disk_module
    

    Source File:mod_cache_disk.c
    

    Summary
    

    
    mod_cache_disk implements a disk based storage
    manager for mod_cache.
    

    
    The headers and bodies of cached responses are stored separately on
    disk, in a directory structure derived from the md5 hash of the cached
    URL.
    

    
    Multiple content negotiated responses can be stored concurrently,
    however the caching of partial content is not yet supported by this
    module.
    

    
    Atomic cache updates to both header and body files are achieved
    without the need for locking by storing the device and inode numbers of
    the body file within the header file. This has the side effect that
    cache entries manually moved into the cache will be ignored.
    

    
    The htcacheclean tool is provided to list cached
    URLs, remove cached URLs, or to maintain the size of the disk cache
    within size and/or inode limits. The tool can be run on demand, or
    can be daemonized to offer continuous monitoring of directory sizes.
    

    
    Note:
    
      
    mod_cache_disk requires the services of
      mod_cache, which must be
      loaded before mod_cache_disk.
    
    
    
    
    Note:
    
      
    mod_cache_disk uses the sendfile feature to
      serve files from the cache when supported by the platform, and
      when enabled with EnableSendfile.
      However, per-directory and .htaccess configuration of
      EnableSendfile are ignored by
      mod_cache_disk as the corresponding settings are not
      available to the module when a request is being served from the
      cache.

    Module:mod_cache_disk
    

    
    
    The CacheDirLength directive sets the number
    of characters for each subdirectory name in the cache hierarchy. It can
    be used in conjunction with CacheDirLevels to
    determine the approximate structure of your cache hierarchy.
    
    
    A high value for CacheDirLength combined
    with a low value for CacheDirLevels will result in
    a relatively flat hierarchy, with a large number of subdirectories at each
    level.
    

    
    
      
    The result of CacheDirLevels* CacheDirLength
      must not be higher than 20.

    Status:Extension
    

    Module:mod_cache_disk
    

    
    
    The CacheDirLevels directive sets the number
    of subdirectory levels in the cache. Cached data will be saved this
    many directory levels below the CacheRoot directory.
    
    
    A high value for CacheDirLevels combined
    with a low value for CacheDirLength will result in
    a relatively deep hierarchy, with a small number of subdirectories at each
    level.
    

    
    
      
    The result of CacheDirLevels*
      CacheDirLength must
      not be higher than 20.

    Status:Extension
    

    Module:mod_cache_disk
    

    
    
    The CacheReadSize directive sets the
    minimum amount of data, in bytes, to be read from the backend before the
    data is sent to the client. The default of zero causes all data read of
    any size to be passed downstream to the client immediately as it arrives.
    Setting this to a higher value causes the disk cache to buffer at least
    this amount before sending the result to the client. This can improve
    performance when caching content from a reverse proxy.
    

    
    This directive only takes effect when the data is being saved to the
    cache, as opposed to data being served from the cache.

    Status:Extension
    

    Module:mod_cache_disk
    

    
    
    The CacheReadTime directive sets the minimum amount
    of elapsed time that should pass before making an attempt to send data
    downstream to the client. During the time period, data will be buffered
    before sending the result to the client. This can improve performance when
    caching content from a reverse proxy.
    

    
    The default of zero disables this option.
    

    
    This directive only takes effect when the data is being saved to the
    cache, as opposed to data being served from the cache. It is recommended
    that this option be used alongside the
    CacheReadSize directive to
    ensure that the server does not buffer excessively should data arrive faster
    than expected.
    

    
    CacheReadTime 1000

    CacheRoot Directive
    

    

    Description:The directory root under which cache files are
stored
    

    Syntax:CacheRoot directory
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_cache_disk
    

    
    
    The CacheRoot directive defines the name of
    the directory on the disk to contain cache files. If the mod_cache_disk module has been loaded or compiled in to the
    Apache server, this directive must be defined. Failing to
    provide a value for CacheRoot will result in
    a configuration file processing error. The CacheDirLevels and CacheDirLength directives define
    the structure of the directories under the specified root directory.
    

    
    CacheRoot c:/cacheroot

    Description:Fait traiter le corps de la réponse par un programme
externe avant de l'envoyer au client

    Sommaire
    

    
    mod_ext_filter représente un modèle de
    programmation simple et bien connu pour les filtres. Avec ce module, tout programme
    qui lit l'entrée standard stdin et écrit sur la sortie standard
    stdout (autrement dit une commande filtre de style Unix) peut
    servir de filtre pour Apache. Ce mécanisme de filtrage est beaucoup
    plus lent qu'un filtre spécialement écrit pour
    l'API d'Apache et faisant partie intégrante du processus du serveur
    Apache, mais il présente les avantages suivants :
    

    
      
      
    • le modèle de programmation est beaucoup plus simple
      • 

      
    • tout langage de script ou de programmation peut être utilisé,
      pourvu qu'il permette au programme de lire l'entrée standard et
      d'écrire sur la sortie standard.
      • 

      
    • on peut utiliser des programmes existants comme filtres Apache
      sans modification.
      • 
    
    

    
    Même dans le cas où le niveau de performance est insuffisant pour
    une utilisation en production, on peut utiliser
    mod_ext_filter comme prototype d'environnement pour
    les filtres.

# Notez que sans le paramètre ftype, le type de filtre par

# mod_deflate dans la chaîne de filtrage. Le fait d'affecter
# à ce paramètre une valeur numérique sensiblement supérieure à

    Voici le filtre qui trace les données :
    #!/usr/local/bin/perl -w
use strict;

open(SAVE, ">$ARGV[0]")
    or die "can't open $ARGV[0]: $?";

while (<STDIN>) {
    print SAVE $_;

    Directive ExtFilterDefine
    

    

    Description:Définit un filtre externe
    

    Syntaxe:ExtFilterDefine nom_filtre paramètres
    

    Contexte:configuration globale
    

    Statut:Extension
    

    Module:mod_ext_filter
    

    
    
    La directive ExtFilterDefine
    définit les caractéristiques d'un filtre externe, et en particulier
    le programme à exécuter ainsi que ses arguments.
    

    
    nom_filtre spécifie le nom du filtre en cours de
    définition. On peut ensuite utiliser ce nom pour référencer le
    filtre dans les directives SetOutputFilter. Il doit être unique parmi les noms de
    tous les filtres enregistrés. Pour le moment, aucune erreur
    n'est signalée par l'API register-filter, si bien qu'un problème de
    noms dupliqués ne sera pas porté à la connaissance de
    l'utilisateur.
    

    
    Viennent ensuite un ou plusieurs paramètres dans un ordre
    indéfini, qui permettent de spécifier la commande externe à exécuter
    et certaines autres caractéristiques. Le seul paramètre obligatoire
    est cmd=. Voici la liste de ces paramètres :
    

    
    
      
    cmd=ligne de commande
    

      
    Le mot-clé cmd= spécifie la commande
      externe à exécuter. Si la ligne de commande comporte des
      arguments, elle doit être entourée de guillemets (par exemple
      cmd="/bin/mypgm arg1
      arg2"). Les guillemets habituels du shell ne
      sont pas nécessaires car le programme est lancé directement, sans
      passer par le shell. Les arguments du programme doivent être
      séparés par des espaces. Si un argument contient des espaces, ces
      derniers doivent être échappés par un antislash '\'. Si un
      argument contient des antislashes '\', ces derniers doivent être
      eux-mêmes échappés par un antislash '\'. Outre les variables
      d'environnement CGI standards, les variables DOCUMENT_URI,
      DOCUMENT_PATH_INFO, et QUERY_STRING_UNESCAPED seront également
      définies pour le programme.
    

      
    mode=mode
    

      
    Utilisez mode=output (valeur par défaut) pour les
      filtres qui traitent les réponses. Utilisez
      mode=input pour les filtres qui traitent les
      requêtes. mode=input est disponible depuis la version
      2.1 d'Apache.
    

      
    intype=type MIME
    

      
    Ce paramètre spécifie le type de médium Internet
      (c'est à dire le type MIME) des documents qui doivent être
      filtrés. Par défaut, tous les documents sont filtrés. Aucun des
      documents possédant un type MIME autre que celui spécifié par
      intype= ne sera filtré.
    

      
    outtype=type MIME
    

      
    Ce paramètre spécifie le type de médium Internet
      (c'est à dire le type MIME) des documents filtrés. Il intervient
      lorsque les opérations de filtrage comprennent une modification du
      type MIME. Par défaut, le type MIME n'est pas modifié.
    

      
    PreservesContentLength
    

      
    Le mot-clé PreservesContentLength indique que le
      filtre doit conserver la taille du contenu. Ce n'est pas le
      comportement par défaut, car la plupart des filtres modifient cette
      taille. Ce mot-clé doit être spécifié si le filtre ne doit pas
      modifier la taille du contenu.
    

      
    ftype=type de filtre
    

      
    Ce paramètre spécifie une valeur numérique
      représentant le type de filtre sous lequel le filtre doit être
      enregistré. La valeur par défaut, AP_FTYPE_RESOURCE, convient dans
      la plupart des situations. Ce paramètre devient nécessaire dès lors
      que le filtre doit opérer à un autre point de la chaîne de filtrage
      que les filtres de ressources.
      Voir les définitions de AP_FTYPE_...
      dans util_filter.h pour trouver une valeur appropriée.
    

      
    disableenv=env
    

      
    Ce paramètre spécifie le nom d'une variable
      d'environnement qui, si elle est définie, va désactiver le
      filtre.
    

      
    enableenv=env
    

      
    Ce paramètre spécifie le nom d'une variable
      d'environnement qui doit être définie pour que le filtre ne soit
      pas désactivé.

    Statut:Extension
    

    Module:mod_ext_filter
    

    
    
    La directive ExtFilterOptions
    spécifie des options de traitement particulières pour
    mod_ext_filter. Les arguments option
    peuvent contenir :
    

    
    
      
    LogStderr | NoLogStderr
    

      
    Le mot-clé LogStderr indique que les messages
      envoyés par le programme de filtrage externe sur la sortie
      d'erreurs standard doivent être enregistrés dans le journal des
      erreurs d'Apache. NoLogStderr inverse ce
      comportement.
    

      
    Onfail=[abort|remove]
    
      
    Indique la marche à suivre si le programme de filtrage externe
      ne peut pas démarrer. Avec abort (la valeur par
      défaut), le traitement de la requête sera abandonné. Avec remove, le
      filtre est supprimé, et le traitement de la requête se poursuit
      sans lui.
    
    
    

    
    ExtFilterOptions LogStderr
    


    
    Les messages envoyés vers la sortie d'erreurs standard du filtre
    seront enregistrés dans le journal des erreurs d'Apache.

    Description:Module de support AJP pour
mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_ajp_module
    

    Fichier Source:mod_proxy_ajp.c
    

    Compatibilité:Disponible à partir de la version 2.1 du serveur HTTP
Apache
    

    Sommaire
    

    
    Ce module nécessite le chargement de mod_proxy. Il fournit le support du Protocole Apache
    JServ version 1.3 (nommé dans la suite de ce document
    AJP13).
    

    
    Pour être en mesure d'exploiter le protocole AJP13,
    il est donc nécessaire de charger les modules
    mod_proxy et mod_proxy_ajp.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large. 
    
    
    

    


    top
    

    

    Utilisation
    
    
    Ce module permet de mandater en inverse un serveur d'application
    d'arrière-plan (comme Apache Tomcat) qui utilise le protocole AJP13.
    Son utilisation est similaire à celle d'un mandataire inverse HTTP,
    mais s'appuie sur le prefixe ajp:// :
    

    
    Mandataire inverse simple
    ProxyPass "/app" "ajp://backend.example.com:8009/app"
    

    

    
    Les options telles que l'option secret de Tomcat (requise
    par défaut depuis Tomcat 8.5.51 et 9.0.31) peut tout simplement être ajoutée
    en tant que paramètre séparé à la fin des directives ProxyPass ou BalancerMember. Ce paramètre est disponible à
    partir de la version 2.4.42 du serveur HTTP Apache :
    
    
    Mandataire inverse simple avec l'option secret
    ProxyPass "/app" "ajp://backend.example.com:8009/app" secret=YOUR_AJP_SECRET
    

    

    
    On peut aussi configurer un répartiteur de charge :
    
    
    Mandataire inverse avec répartiteur de charge
    <Proxy "balancer://cluster">
    BalancerMember "ajp://app1.example.com:8009" loadfactor=1
    BalancerMember "ajp://app2.example.com:8009" loadfactor=2
    ProxySet lbmethod=bytraffic
</Proxy>
ProxyPass "/app" "balancer://cluster/app"
    

    

    
    Notez qu'en général, la directive ProxyPassReverse n'est pas
    nécessaire. La requête AJP inclut l'en-tête host original fourni
    au mandataire, et le serveur d'application est sensé générer des
    en-têtes auto-référençants relatifs à cet hôte ; aucune réécriture
    n'est donc nécessaire.
    

    
    La situation la plus courante dans laquelle la directive ProxyPassReverse est nécessaire se
    rencontre lorsque le chemin de l'URL au niveau du mandataire est
    différente de celle du serveur d'arrière-plan. Dans ce cas, un
    en-tête redirect peut être réécrit relativement à l'URL de l'hôte
    original (et non du serveur d'arrière-plan ajp:// URL)
    ; par exemple :
    
    
    Réécriture d'un chemin mandaté
    ProxyPass "/apps/foo" "ajp://backend.example.com:8009/foo"
ProxyPassReverse "/apps/foo" "http://www.example.com/foo"
    

    
    
    Il est cependant préférable en général de déployer l'application
    sur le serveur d'arrière-plan avec le même chemin que sur le
    mandataire.
    
    

    top
    

    

    Variables d'environnement
    
    
    Les variables d'environnement dont le nom possède le préfixe
    AJP_ sont transmises au serveur original en tant
    qu'attributs de requête AJP (le préfixe AJP_ étant supprimé du
    nom de la clé).
    

    top
    

    

    Vue d'ensemble du protocole
    
    
    Le protocole AJP13 est orienté paquet. Le format
    binaire a été préféré, probablement pour des raisons de
    performances, au format texte pourtant plus lisible. Le serveur web
    communique avec le conteneur de servlets sur une connexion TCP. Pour
    diminuer la charge induite par le processus de création de socket,
    le serveur web va tenter d'utiliser des connexions TCP persistantes
    avec le conteneur de servlets, et de réutiliser les connexions
    pendant plusieurs cycles requêtes/réponse.
    
    
    Lorsqu'une connexion a été assignée à une requête particulière,
    elle ne sera utilisée pour aucune autre jusqu'à ce que le cycle de
    traitement de la requête se soit terminé. En d'autres termes, il n'y
    a pas de multiplexage des requêtes sur une connexion. Ceci se
    traduit par un code beaucoup plus simple à chaque extrémité de la
    connexion, un nombre plus important de connexions étant cependant
    ouvertes en même temps.
    
    
    Lorsque le serveur web a ouvert une connexion vers le conteneur
    de servlets, celle-ci peut se trouver dans l'un des états suivants
    :
    
    
      
    
    •  Idle 
       Aucune requête n'est traitée sur cette
    connexion. 
      • 
    
    •  Assigned 
       La connexion fait l'objet d'un traitement de
    requête.
      • 
    
    
    
    Lorsqu'une connexion est assignée au traitement d'une requête
    particulière, les informations de base de cette dernière (comme les
    en-têtes HTTP, etc...) sont envoyées sur la connexion sous une forme
    très condensée (par exemple les chaînes courantes sont codées sous
    forme d'entiers). Vous trouverez des détails sur ce format plus
    loin dans la structure des paquets de requête. Si la requête possède
    un corps (content-length > 0), il est envoyé dans un
    paquet séparé immédiatement après.
    
    
    A ce moment, le conteneur est probablement prêt à traiter la
    requête. Au cours de ce traitement, il peut renvoyer les messages
    suivants au serveur web :
    
    
      
    
    • SEND_HEADERS 
      Renvoie un jeu d'en-têtes au navigateur.
      • 
    
    • SEND_BODY_CHUNK 
      Renvoie un tronçon de corps de requête au
    navigateur.
    
      • 
    
    • GET_BODY_CHUNK 
      Reçoit un autre tronçon de données de la
    requête si elle n'a pas encore été transmise intégralement. Ce type
    de transmission est nécessaire car les paquets possèdent une taille
    maximale fixe, et des quantités quelconques de données peuvent être
    contenues dans le corps de la requête (pour un chargement de
    fichier, par exemple). Notez que cela n'a rien à voir avec le
    transfert HTTP fractionné.
      • 
    
    • END_RESPONSE 
       Termine le cycle du traitement de la
    requête.
      • 
    
    
    
    Chaque message est associé à un paquet de données formaté
    différemment. Voir plus loin les structures des paquets de réponses
    pour plus de détails.

    Structure de base des paquets
    
    
    Ce protocole hérite en partie de XDR, mais il diffère sur de
    nombreux points (pas d'alignement sur 4 bits, par exemple).
    
    
    AJP13 utilise les octets selon leur ordre d'arrivée par le réseau
    pour tous les types de données.
    
    
    Le protocole comporte quatre types de données : octets, booléens,
    entiers et chaînes de caractères.
    
    
    
    
    Octet
    Un seul octet.
    
    
    Booléen
    
      
    Un seul octet, 1 = vrai, 0 = faux.
      L'utilisation d'autres valeurs non nulles (dans le style C) peut
      fonctionner dans certains cas, mais pas dans certains autres..
    
    
    Entier
    
      
    Un nombre compris entre 0 et 2^16 (32768), stocké
      sur 2 octets en débutant par l'octet de poids forts.
    
    
    Chaîne
    
      
    Une chaîne de taille variable (longueur limitée à 2^16). Elle
      est codée comme suit : les deux premiers octets représentent la
      longueur de la chaîne, les octets suivants constituent la chaîne
      proprement dite (y compris le '\0' final). Notez que la longueur
      encodée dans les deux premiers octets ne prend pas en compte le
      '\0' final, de la même manière que strlen. Cela peut
      prêter à confusion du point de vue de Java qui est surchargé de
      déclarations d'autoincrémentation étranges destinées à traiter
      ces terminateurs. Je suppose que le but dans lequel cela a
      été conçu ainsi était de permettre au code C d'être plus efficace
      lors de la lecture de chaînes en provenance du conteneur de
      servlets -- avec le caractère \0 final, le code C peut transmettre
      des références dans un seul tampon, sans avoir à effectuer de
      copie. En l'absence du caractère \0 final, le code C doit
      effectuer une copie afin de pouvoir tenir compte de sa notion de
      chaîne.
    
    
    

  
    Taille du paquet
    
    
    Selon la majorité du code, la taille maximale du paquet est de
    8 * 1024 bytes (8K). La taille réelle du paquet est
    encodée dans l'en-tête.
    
  
  
    En-têtes de paquet
    
    
    Les paquets envoyés par le serveur vers le conteneur commencent
    par 0x1234. Les paquets envoyés par le conteneur vers
    le serveur commencent par AB (c'est à dire le code
    ASCII de A suivi du code ASCII de B). Ensuite, vient un entier (codé
    comme ci-dessus) représentant la longueur des données transmises.
    Bien que ceci puisse faire croire que la taille maximale des données
    est de 2^16, le code définit en fait ce maximum à 8K.

    Pour la plupart des paquets, le premier octet de la charge utile
    encode le type de message, à l'exception des paquets contenant un
    corps de requête envoyés du serveur vers le conteneur -- ils
    comportent un en-tête standard (0x1234 suivi de la taille
    du paquet), mais celui-ci n'est suivi d'aucun préfixe.

    Les significations de ces éléments sont triviales. Ils sont tous
    obligatoires et seront envoyés avec chaque requête.
    
  
  
    En-têtes
    
    
    La structure de request_headers est la suivante
    : tout d'abord, le nombre d'en-têtes num_headers est
    encodé, suivi d'une liste de paires nom d'en-tête
    req_header_name / valeur req_header_value.
    Les noms d'en-têtes courants sont codés sous forme d'entiers afin de
    gagner de la place. Si le nom d'en-tête ne fait partie de la liste
    des en-têtes courants, il est encodé normalement (une chaîne de
    caractères préfixée par la taille). La liste des en-têtes courants
    sc_req_header_name avec leurs codes se présente comme
    suit (il sont tous sensibles à la casse) :
    
    
    
      
    NomValeur du codeNom du code
    
      
    accept0xA001SC_REQ_ACCEPT

    user-agent0xA00ESC_REQ_USER_AGENT
    
    
    
    
    Le code Java qui lit ceci extrait l'entier représenté par les
    deux premiers octets, et si le premier octet est
    '0xA0', il utilise l'entier représenté par le deuxième
    octet comme index d'un tableau de noms d'en-têtes. Si le premier
    octet n'est pas 0xA0, l'entier représenté par les deux
    octets est considéré comme la longueur d'une chaîne qui est alors
    lue.
    
    
    Ceci ne peut fonctionner que si aucun nom d'en-tête ne possède
    une taille supérieure à 0x9FFF (==0xA000 - 1), ce qui
    est vraisemblable, bien qu'un peu arbitraire.
    
    
    Note:
    
    L'en-tête content-length est extrêmement important.
    S'il est présent et non nul, le conteneur considère que la requête
    possède un corps (une requête POST, par exemple), et lit
    immédiatement le paquet suivant dans le flux d'entrée pour extraire
    ce corps.
    
    
  
  
    Attributs
    
    
    Les attributs préfixés par ? (par exemple
    ?context) sont tous optionnels. Chacun d'eux est
    représenté par un octet correspondant au type de l'attribut et par
    sa valeur (chaîne ou entier). Ils peuvent être envoyés dans un ordre
    quelconque (bien que le code C les envoie dans l'ordre ci-dessous).
    Un code de terminaison spécial est envoyé pour signaler la fin de la
    liste des attributs optionnels. La liste des codes est la suivante
    :
    
    
    
      
    InformationValeur codeType de valeurNote

    ?secret0x0CStringSupporté depuis la
      version 2.4.42
    
      
    are_done0xFF-request_terminator
    
    
    
    
    context et servlet_path ne sont pas
    définis actuellement par le code C, et la majorité du code Java
    ignore complètement ce qui est envoyé par l'intermédiaire de ces
    champs (il va même parfois s'interrompre si une chaîne est
    envoyée après un de ces codes). Je ne sais pas si c'est une bogue ou
    une fonctionnalité non implémentée, ou tout simplement du code
    obsolète, mais en tout cas, il n'est pris en charge par aucune des
    deux extrémités de la connexion.
    
    
    remote_user et auth_type concernent
    probablement l'authentification au niveau HTTP, et contiennent le
    nom de l'utilisateur distant ainsi que le type d'authentification
    utilisée pour établir son identité (à savoir Basic, Digest).
    
    
    query_string, ssl_cert,
    ssl_cipher, ssl_session et
    ssl_key_size contiennent les
    éléments HTTP et HTTPS correspondants.
    
    
    jvm_route est utilisé dans le cadre des sessions
    persistantes, en associant une session utilisateur à une instance
    Tomcat particulière en présence de plusieurs répartiteurs de
    charge.
    
    
    Le mot de passe est envoyé lorsque la directive ProxyPass ou BalancerMember utilise le paramètre
    secret=secret_keyword. Le serveur d'arrière-plan doit savoir
    utiliser les mots de passe et les valeurs doivent correspondre.
    request.secret ou requiredSecret sont documentés
    dans la configuration AJP d'Apache Tomcat.
    
    
    Au delà de cette liste de base, tout autre attribut
    supplémentaire peut être envoyé via le code
    req_attribute 0x0A. Une paire de chaînes
    représentant le nom et la valeur de l'attribut est envoyée
    immédiatement après chaque instance de ce code. Les variables
    d'environnement sont transmises par cette méthode.
    
    
    Enfin, lorsque tous les attributs ont été transmis, le
    terminateur d'attributs, 0xFF, est envoyé. Ce dernier
    indique à la fois la fin de la liste d'attributs et la fin du paquet
    de la requête

    requêtes entrantes. Si reuse est à false
    (==0), la connexion sera fermée.
    
  
  
    Réception d'un tronçon de corps
    
    
    Le conteneur réclame la suite des données de la requête (dans le
    cas où la taille du corps était trop importante pour pouvoir être
    contenue dans le premier paquet envoyé, où lorsque la requête est
    fractionnée). Le serveur va alors envoyer un paquet contenant une
    quantité de données correspondant au minimum de la
    request_length, la taille maximale de corps envoyée
    (8186 (8 Koctets - 6)), et le nombre réel d'octets
    restants à envoyer pour ce corps de requête.
    
    S'il ne reste plus de données à transmettre pour ce corps de requête
    (c'est à dire si le conteneur de servlets tente de lire au delà de
    la fin du corps), le serveur va renvoyer un paquet vide
    dont la charge utile est de longueur 0 et se présentant sous la
    forme (0x12,0x34,0x00,0x00).

    Apache Module mod_brotli
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Compress content via Brotli before it is delivered to the
client
    

    Status:Extension
    

    Module Identifier:brotli_module
    

    Source File:mod_brotli.c
    

    Compatibility:Available in version 2.4.26 and later.
    

    Summary
    

    
    The mod_brotli module provides
    the BROTLI_COMPRESS output filter that allows output from
    your server to be compressed using the brotli compression format before being sent to the client over
    the network. This module uses the Brotli library found at
    https://github.com/google/brotli.

    Sample Configurations
    
    
    Compression and TLS
    
        
    Some web applications are vulnerable to an information disclosure
        attack when a TLS connection carries compressed data. For more
        information, review the details of the "BREACH" family of attacks.
    
    
    
    
    This is a simple configuration that compresses common text-based content types.
    

    
    Compress only a few types
    AddOutputFilterByType BROTLI_COMPRESS text/html text/plain text/xml text/css text/javascript application/javascript

    Enabling Compression
    
    
    Compression and TLS
    
        
    Some web applications are vulnerable to an information disclosure
        attack when a TLS connection carries compressed data. For more
        information, review the details of the "BREACH" family of attacks.
    
    
    

    
    Output Compression
    
      
    Compression is implemented by the BROTLI_COMPRESS
      filter. The following directive
      will enable compression for documents in the container where it
      is placed:
    

      
    SetOutputFilter BROTLI_COMPRESS
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-brotli
    


      
    If you want to restrict the compression to particular MIME types
      in general, you may use the AddOutputFilterByType directive. Here is an example of
      enabling compression only for the html files of the Apache
      documentation:
    

      
    <Directory "/your-server-root/manual">
    AddOutputFilterByType BROTLI_COMPRESS text/html
</Directory>
    


      
    Note
    
        The BROTLI_COMPRESS filter is always inserted after RESOURCE
        filters like PHP or SSI. It never touches internal subrequests.
      
    
      
    Note
    
        There is an environment variable no-brotli,
        set via SetEnv, which
        will disable brotli compression for a particular request, even if
        it is supported by the client.
      
    

    


    top
    

    

    Dealing with proxy servers
    

    
    The mod_brotli module sends a Vary:
    Accept-Encoding HTTP response header to alert proxies that
    a cached response should be sent only to clients that send the
    appropriate Accept-Encoding request header.  This
    prevents compressed content from being sent to a client that will
    not understand it.
    

    
    If you use some special exclusions dependent
    on, for example, the User-Agent header, you must
    manually configure an addition to the Vary header
    to alert proxies of the additional restrictions.  For example,
    in a typical configuration where the addition of the BROTLI_COMPRESS
    filter depends on the User-Agent, you should add:
    

    
    Header append Vary User-Agent
    


    
    If your decision about compression depends on other information
    than request headers (e.g. HTTP version), you have to set the
    Vary header to the value *. This prevents
    compliant proxies from caching entirely.
    

    
    Example
    Header set Vary *
    

    

    top
    

    

    Serving pre-compressed
content
    

    
    Since mod_brotli re-compresses content each
    time a request is made, some performance benefit can be derived by
    pre-compressing the content and telling mod_brotli to serve them
    without re-compressing them. This may be accomplished using a
    configuration like the following:
    

    
    <IfModule mod_headers.c>
    # Serve brotli compressed CSS files if they exist
    # and the client accepts brotli.
    RewriteCond "%{HTTP:Accept-encoding}" "br"
    RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
    RewriteRule "^(.*)\.css"              "$1\.css\.br" [QSA]

    # Serve brotli compressed JS files if they exist
    # and the client accepts brotli.
    RewriteCond "%{HTTP:Accept-encoding}" "br"
    RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
    RewriteRule "^(.*)\.js"               "$1\.js\.br" [QSA]


    # Serve correct content types, and prevent double compression.
    RewriteRule "\.css\.br$" "-" [T=text/css,E=no-brotli:1]
    RewriteRule "\.js\.br$"  "-" [T=text/javascript,E=no-brotli:1]


    <FilesMatch "(\.js\.br|\.css\.br)$">
      # Serve correct encoding type.
      Header append Content-Encoding br

      # Force proxies to cache brotli &
      # non-brotli css/js files separately.
      Header append Vary Accept-Encoding
    </FilesMatch>
</IfModule>

    BrotliAlterETag Directive
    

    

    Description:How the outgoing ETag header should be modified during compression
    

    Syntax:BrotliAlterETag AddSuffix|NoChange|Remove
    

    Default:BrotliAlterETag AddSuffix
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_brotli
    

    
    
    The BrotliAlterETag directive specifies
    how the ETag hader should be altered when a response is compressed.
    
    
    
    
    AddSuffix
    
    
    Append the compression method onto the end of the ETag, causing
        compressed and uncompressed representations to have unique ETags.
        In another dynamic compression module, mod_deflate, this has been
        the default since 2.4.0. This setting prevents serving "HTTP Not
        Modified" (304) responses to conditional requests for compressed
        content.
    
    
    NoChange
    
    
    Don't change the ETag on a compressed response. In another dynamic
        compression module, mod_deflate, this has been the default prior to
        2.4.0. This setting does not satisfy the HTTP/1.1 property that all
        representations of the same resource have unique ETags. 
    
    
    Remove
    
    
    Remove the ETag header from compressed responses. This prevents
        some conditional requests from being possible, but avoids the
        shortcomings of the preceding options.

    Status:Extension
    

    Module:mod_brotli
    

    
    
    The BrotliCompressionMaxInputBlock directive specifies
    the maximum input block size between 16 and 24, with the caveat that
    larger block sizes require more memory.

    BrotliCompressionQuality Directive
    

    

    Description:Compression quality

    Status:Extension
    

    Module:mod_brotli
    

    
    
    The BrotliCompressionQuality directive specifies
    the compression quality (a value between 0 and 11). Higher quality values
    result in better, but also slower compression.

    Module:mod_brotli
    

    
    
    The BrotliCompressionWindow directive specifies the
    brotli sliding compression window size (a value between 10 and 24). Larger
    window sizes can improve compression quality, but require more memory.

    BrotliFilterNote Directive
    

    

    Description:Places the compression ratio in a note for logging
    

    Syntax:BrotliFilterNote [type] notename
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_brotli
    

    
    
    The BrotliFilterNote directive
    specifies that a note about compression ratios should be attached
    to the request. The name of the note is the value specified for
    the directive. You can use that note for statistical purposes by
    adding the value to your access log.
    

    
    Example
    BrotliFilterNote ratio

LogFormat '"%r" %b (%{ratio}n) "%{User-agent}i"' brotli
CustomLog "logs/brotli_log" brotli
    

    

    
    If you want to extract more accurate values from your logs, you
    can use the type argument to specify the type of data
    left as a note for logging. type can be one of:
    

    
    
      
    Input
    
      
    Store the byte count of the filter's input stream in the note.
    

      
    Output
    
      
    Store the byte count of the filter's output stream in the note.
    

      
    Ratio
    
      
    Store the compression ratio (output/input * 100)
      in the note. This is the default, if the type argument
      is omitted.
    
    
    

    
    Thus you may log it this way:
    

    
    Accurate Logging
    BrotliFilterNote Input instream
BrotliFilterNote Output outstream
BrotliFilterNote Ratio ratio

LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' brotli
CustomLog "logs/brotli_log" brotli

    Sommaire
    

    
    Ce module interroge un démon compatible RFC 1413 sur un
    serveur distant afin de déterminer le propriétaire d'une
    connexion.

    Directive IdentityCheck
    

    

    Description:Active la journalisation de l'identité RFC 1413 de
l'utilisateur distant
    

    Syntaxe:IdentityCheck On|Off
    

    Défaut:IdentityCheck Off

    Statut:Extension
    

    Module:mod_ident
    

    Compatibilité:Retiré du serveur de base depuis Apache
2.1
    

    
    
    Cette directive permet d'activer la journalisation compatible RFC 1413 du nom de
    l'utilisateur distant pour chaque connexion, si la machine du client
    exécute identd ou un démon similaire. Cette information est
    enregistrée dans le journal des accès en utilisant la chaîne de formatage
    %...l.
    

    
    
      Cette information ne doit pas faire l'objet d'une confiance
      absolue, et elle ne doit être utilisée que dans le cadre d'un
      traçage grossier.
    
    

    
    Notez que de sérieux problèmes de délais peuvent survenir lors
    des accès à votre serveur, car chaque requête nécessite l'exécution
    d'un de ces processus de recherche. Lorsque des pare-feu ou des
    serveurs mandataires sont impliqués, chaque recherche est
    susceptible d'échouer et ajouter un temps de latence conformément
    à la directive IdentityCheckTimeout. En général, ces
    recherches ne se révèlent donc pas très utiles sur des serveurs
    publics accessibles depuis l'Internet.

    Module:mod_ident
    

    
    
    Cette directive permet de spécifier le délai d'attente d'une
    requête ident. Une valeur par défaut de 30 secondes est recommandée
    par la RFC 1413,
    principalement pour prévenir les problèmes qui pourraient être
    induits par la charge du réseau. Vous pouvez cependant ajuster la
    valeur de ce délai en fonction du débit de votre réseau local.

    Module Apache mod_authn_dbd
    

    

    Langues Disponibles:  en  |

    Description:Authentification utilisateur à l'aide d'une base de données
SQL
    

    Statut:Extension
    

    Identificateur de Module:authn_dbd_module
    

    Fichier Source:mod_authn_dbd.c
    

    Compatibilité:Disponible depuis la version 2.1 d'Apache
    

    Sommaire
    

    
    Ce module permet aux frontaux d'authentification comme
    mod_auth_digest et mod_auth_basic
    d'authentifier les utilisateurs en les recherchant dans une base de
    données SQL. mod_authn_file, par exemple, fournit
    une fonctionnalité similaire.
    
    
    Ce module s'appuie sur mod_dbd pour spécifier le
    pilote de la base de données sous-jacente et les paramètres de
    connexion, mais aussi pour gérer les connexions à la base de
    données.
    

    
    Si l'on utilise mod_auth_basic ou
    mod_auth_digest, on peut invoquer ce module en
    affectant la valeur dbd à la directive AuthBasicProvider ou AuthDigestProvider.

    Performances et mise en cache
    


    Certains utilisateurs de l'authentification DBD sous HTTPD 2.2/2.4 ont
signalé une charge problématique au niveau de la base de données. Cela
se produit en général lorsqu'une page HTML contient des centaines d'objets
(comme des images, des scripts, etc...), chacun d'entre eux nécessitant
une authentification. Les utilisateurs qui rencontrent ce genre de
problème peuvent utiliser le module mod_authn_socache
qui permet de mettre les données d'authentification en cache, et
soulager ainsi la base de données de la plus grande partie de la charge.
    

    top
    

    

    Exemple de configuration
    


    Voici un exemple simple d'utilisation de ce module dans un contexte
d'authentification et de bases de données.
    

    # configuration de mod_dbd
# MISE À JOUR pour inclure la mise en cache de l'authentification
DBDriver pgsql
DBDParams "dbname=apacheauth user=apache password=xxxxxx"

DBDMin  4
DBDKeep 8
DBDMax  20
DBDExptime 300

<Directory "/usr/www/mon-serveur/private">
  # configuration de mod_authn_core et mod_auth_basic
  # pour mod_authn_dbd
  AuthType Basic
  AuthName "Mon serveur"

  # Pour mettre en cache les données d'authentification, placez socache
  # avant dbd
  AuthBasicProvider socache dbd

  # Aussi nécessaire à la mise en cache : dire au cache de mettre en
  # cache les recherches dbd !
  AuthnCacheProvideFor dbd
  AuthnCacheContext mon-serveur

  # configuration de mod_authz_core
  Require valid-user

  # la requête SQL de mod_authn_dbd pour authentifier un utilisateur
  AuthDBDUserPWQuery "SELECT password FROM authn WHERE user = %s"
</Directory>

    Mise à disposition des informations de connexion
    


    
Si httpd a été compilé avec la version 1.3.0 ou supérieure de
l'APR, pour chaque requête envoyée au serveur de
base de données, toutes les valeurs de colonnes du premier
enregistrement renvoyé par la requête sont affectées à des variables
d'environnement avec le préfixe "AUTHENTICATE_".

    

    Par exemple, si une requête renvoie un nom d'utilisateur, un nom
complet et un numéro de téléphone, un programme CGI pourra accéder à ces
informations sans avoir besoin d'effectuer une deuxième requête vers la
base de données.
    

    Ceci va entraîner une simplification considérable du code et de la
configuration nécessaire de certaines applications web.

    en utilisant le spécificateur de format %s.
    
    
    AuthDBDUserPWQuery "SELECT password FROM authn WHERE user = %s"
    

    
    La première colonne du premier enregistrement renvoyé par la
    requête se présentera sous la forme d'une chaîne de caractères
    contenant le mot de passe chiffré. Les enregistrements suivants sont
    ignorés. Si aucun enregistrement n'est renvoyé, l'utilisateur ne
    sera pas authentifié par mod_authn_dbd.
    
    
    Si httpd a été compilé avec la version 1.3.0 ou supérieure de
    l'APR, toute valeur de colonne supplémentaire
    du premier enregistrement renvoyé par la requête sera stockée dans
    une variable d'environnement dont le nom aura la forme
    AUTHENTICATE_valeur-colonne.
    
    
    
    Le format du mot de passe chiffré dépend du frontal
    d'authentification utilisé (par exemple
    mod_auth_basic ou

    Description:Logging of the requests made to the server
    

    Status:Base
    

    Module Identifier:log_config_module
    

    Source File:mod_log_config.c
    

    Summary
    

    
    This module provides for flexible logging of client
    requests. Logs are written in a customizable format, and may be
    written directly to a file, or to an external program.
    Conditional logging is provided so that individual requests may
    be included or excluded from the logs based on characteristics
    of the request.
    

    
    Three directives are provided by this module:
    TransferLog to create
    a log file, LogFormat
    to set a custom format, and CustomLog to define a log file and format in one
    step. The TransferLog and CustomLog directives can be used multiple times in each
    server to cause each request to be logged to multiple files.
    

    


    top
    

    

    Custom Log Formats
    

    
    The format argument to the LogFormat and CustomLog directives is a string. This string is
    used to log each request to the log file. It can contain literal
    characters copied into the log files and the C-style control
    characters "\n" and "\t" to represent new-lines and tabs.
    Literal quotes and backslashes should be escaped with
    backslashes.
    

    
    The characteristics of the request itself are logged by
    placing "%" directives in the format string, which are
    replaced in the log file by the values as follows:
    

    
    Format String
        Description
    

    %%
        The percent sign.
    

    %a
        Client IP address of the request (see the
        mod_remoteip module).
    

    %{c}a
        Underlying peer IP address of the connection (see the
        mod_remoteip module).
    

    %A
        Local IP-address.
    

    %B
        Size of response in bytes, excluding HTTP headers.
    

    %b
        Size of response in bytes, excluding HTTP headers. In CLF format, i.e.
        a '-' rather than a 0 when no bytes are sent.
    

    %{VARNAME}C
        The contents of cookie VARNAME in the request sent
        to the server. Only version 0 cookies are fully supported.
    

    %D
        The time taken to serve the request, in microseconds.
    

    %{VARNAME}e
        The contents of the environment variable
        VARNAME.
    

    %f
        Filename.
    

    %h
        Remote hostname. Will log the IP address if HostnameLookups is set to
        Off, which is the default. If it logs the hostname
        for only a few hosts, you probably have access control
        directives mentioning them by name. See the Require host
        documentation.
    

    %{c}h
        Like %h, but always reports on the hostname of the
        underlying TCP connection and not any modifications to the 
        remote hostname by modules like mod_remoteip.
    

    %H
        The request protocol.
    

    %{VARNAME}i
        The contents of VARNAME: header line(s)
        in the request sent to the server. Changes made by other
        modules (e.g. mod_headers) affect this.  If you're
        interested in what the request header was prior to when most
        modules would have modified it, use mod_setenvif
        to copy the header into an internal environment variable and log
        that value with the %{VARNAME}e described
        above.
        
    

    %k
        Number of keepalive requests handled on this connection.  Interesting if
          KeepAlive is being used, so that,
          for example, a '1' means the first keepalive request after the initial
          one, '2' the second, etc...;
          otherwise this is always 0 (indicating the initial request).
    

    %l
        Remote logname (from identd, if supplied). This will return a
        dash unless mod_ident is present and IdentityCheck is set
        On.
    

    %L
        The request log ID from the error log (or '-' if nothing has been
            logged to the error log for this request). Look for the
            matching error log line to see what request caused what error.
    

    %m
        The request method.
    

    %{VARNAME}n
        The contents of note VARNAME from another
        module.
    

    %{VARNAME}o
        The contents of VARNAME: header line(s)
        in the reply.
    

    %p
        The canonical port of the server serving the request.
    

    %{format}p
        The canonical port of the server serving the request, or the
        server's actual port, or the client's actual port. Valid formats
        are canonical, local, or remote.
        
    

    %P
        The process ID of the child that serviced the request.
    

    %{format}P
        The process ID or thread ID of the child that serviced the
        request.  Valid formats are pid, tid,
        and hextid.  hextid requires APR 1.2.0 or
        higher.
        
    

    %q
        The query string (prepended with a ? if a query
        string exists, otherwise an empty string).
    

    %r
        First line of request.
    

    %R
        The handler generating the response (if any).
    

    %s
        Status. For requests that have been internally redirected, this is
        the status of the original request. Use %>s
        for the final status.
    

    %t
        Time the request was received, in the format [18/Sep/2011:19:18:28 -0400].
        The last number indicates the timezone offset from GMT
    

    %{format}t
        The time, in the form given by format, which should be in
        an extended strftime(3) format (potentially localized).
        If the format starts with begin: (default) the time is taken
        at the beginning of the request processing. If it starts with
        end: it is the time when the log entry gets written,
        close to the end of the request processing. In addition to the formats
        supported by strftime(3), the following format tokens are
        supported:
        
    
        
    secnumber of seconds since the Epoch
    
        
    msecnumber of milliseconds since the Epoch
    
        
    usecnumber of microseconds since the Epoch
    
        
    msec_fracmillisecond fraction
    
        
    usec_fracmicrosecond fraction
    
        
    
        These tokens can not be combined with each other or strftime(3)
        formatting in the same format string. You can use multiple
        %{format}t tokens instead.
        
    

    %T
        The time taken to serve the request, in seconds.
    

    %{UNIT}T
        The time taken to serve the request, in a time unit given by
        UNIT. Valid units are ms for milliseconds,
        us for microseconds, and s for seconds.
        Using s gives the same result as %T
        without any format; using us gives the same result
        as %D. Combining %T with a unit is
        available in 2.4.13 and later.
    

    %u
        Remote user if the request was authenticated. May be bogus if return status
        (%s) is 401 (unauthorized).
    

    %U
        The URL path requested, not including any query string.
    

    %v
        The canonical ServerName
        of the server serving the request.
    

    %V
        The server name according to the UseCanonicalName setting.
    

    %X
        Connection status when response is completed:

        
    
        
        
    X =
            Connection aborted before the response completed.
    
        
    + =
            Connection may be kept alive after the response is
            sent.
    
        
    - = 
            Connection will be closed after the response is
            sent.
    
        
    

        
    

    %I
        Bytes received, including request and headers. Cannot be zero.
        You need to enable mod_logio to use this.
    

    %O
        Bytes sent, including headers. May be zero in rare cases
        such as when a request is aborted before a response is sent.
        You need to enable mod_logio to use this.
    

    %S
        Bytes transferred (received and sent), including request and headers,
        cannot be zero. This is the combination of %I and %O. You need to
        enable mod_logio to use this.
    

    %{VARNAME}^ti
        The contents of VARNAME: trailer line(s)
        in the request sent to the server.  
    

    %{VARNAME}^to
        The contents of VARNAME: trailer line(s)
        in the response sent from the server.  
    

    

    
    Modifiers
    

      
    Particular items can be restricted to print only for
      responses with specific HTTP status codes by placing a
      comma-separated list of status codes immediately following the
      "%". The status code list may be preceded by a "!" to
      indicate negation.
    

    
    Format String
    Meaning
    

    
    %400,501{User-agent}i
    Logs User-agent on 400 errors and 501 errors only. For
      other status codes, the literal string "-" will be
      logged.
    

    %!200,304,302{Referer}i
    Logs Referer on all requests that do
    not return one of the three specified codes,
    "-" otherwise.
    
    

    

      
    The modifiers "<" and ">" can be used for requests that
      have been internally redirected to choose whether the original
      or final (respectively) request should be consulted.  By
      default, the % directives %s, %U, %T,
      %D, and %r look at the original request
      while all others look at the final request.  So for example,
      %>s can be used to record the final status of
      the request and %<u can be used to record the
      original authenticated user on a request that is internally
      redirected to an unauthenticated resource.
    

    

    
    Format Notes
    

      
    For security reasons, starting with version 2.0.46,
      non-printable and other special characters in %r,
      %i and %o are escaped using
      \xhh sequences, where hh
      stands for the hexadecimal representation of the raw
      byte. Exceptions from this rule are " and
      \, which are escaped by prepending a backslash, and
      all whitespace characters, which are written in their C-style
      notation (\n, \t, etc).  In versions
      prior to 2.0.46, no escaping was performed on these strings so
      you had to be quite careful when dealing with raw log files.
    

      
    Since httpd 2.0, unlike 1.3, the %b and
      %B format strings do not represent the number of
      bytes sent to the client, but simply the size in bytes of the
      HTTP response (which will differ, for instance, if the
      connection is aborted, or if SSL is used).  The %O
      format provided by mod_logio will log the
      actual number of bytes sent over the network.
    

      
    
      
    Note: mod_cache is implemented as a
      quick-handler and not as a standard handler. Therefore, the
      %R format string will not return any handler
      information when content caching is involved.
    
      
    

    

    
    Examples
    

      
    Some commonly used log format strings are:
    

      
    
        
    Common Log Format (CLF)
    
        
    "%h %l %u %t \"%r\" %>s %b"
    

        
    Common Log Format with Virtual Host
    
        
    "%v %h %l %u %t \"%r\" %>s %b"
    

        
    NCSA extended/combined log format
    
        
    "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
        \"%{User-agent}i\""
    

        
    Referer log format
    
        
    "%{Referer}i -> %U"
    

        
    Agent (Browser) log format
    
        
    "%{User-agent}i"
    
      
    

      
    You can use the %{format}t directive multiple
      times to build up a time format using the extended format tokens
      like msec_frac:
    
      
    

    Timestamp including milliseconds
    

    "%{%d/%b/%Y %T}t.%{msec_frac}t %{%z}t"
    

      
    

    

    top
    

    

    Security Considerations
    
    
    See the security tips
    document for details on why your security could be compromised
    if the directory where logfiles are stored is writable by
    anyone other than the user that starts the server.

    BufferedLogs Directive
    

    

    Description:Buffer log entries in memory before writing to disk
    

    Syntax:BufferedLogs On|Off
    

    Default:BufferedLogs Off
    

    Context:server config
    

    Status:Base
    

    Module:mod_log_config
    

    
    
    The BufferedLogs directive causes
    mod_log_config to store several log entries in
    memory and write them together to disk, rather than writing them
    after each request.  On some systems, this may result in more
    efficient disk access and hence higher performance.  It may be
    set only once for the entire server; it cannot be configured
    per virtual-host.
    

    
    This directive should be used with caution as a crash might
    cause loss of logging data.
    


    

    top
    

    CustomLog Directive
    

    

    Description:Sets filename and format of log file
    

    Syntax:CustomLog  file|pipe
format|nickname
[env=[!]environment-variable|
expr=expression]
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_log_config
    

    
    
    The CustomLog directive is used to
    log requests to the server. A log format is specified, and the
    logging can optionally be made conditional on request
    characteristics using environment variables.
    

    
    The first argument, which specifies the location to which
    the logs will be written, can take one of the following two
    types of values:
    

    
    
      
    file
    
      
    A filename, relative to the ServerRoot.
    

      
    pipe
    
      
    The pipe character "|", followed by the path
      to a program to receive the log information on its standard
      input. See the notes on piped logs
      for more information.

      
    Security:
    
      
    If a program is used, then it will be run as the user who
      started httpd. This will be root if the server was
      started by root; be sure that the program is secure.
    
      
    
      
    Note
    
        
    When entering a file path on non-Unix platforms, care should be taken
        to make sure that only forward slashed are used even though the platform
        may allow the use of back slashes. In general it is a good idea to always
        use forward slashes throughout the configuration files.
    
      
    
    
    

    
    The second argument specifies what will be written to the
    log file. It can specify either a nickname defined by
    a previous LogFormat
    directive, or it can be an explicit format string as
    described in the log formats section.
    

    
    For example, the following two sets of directives have
    exactly the same effect:
    

    
    # CustomLog with format nickname
LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog "logs/access_log" common

# CustomLog with explicit format string
CustomLog "logs/access_log" "%h %l %u %t \"%r\" %>s %b"
    


    
    The third argument is optional and controls whether or
    not to log a particular request. The condition can be the
    presence or absence (in the case of a 'env=!name'
    clause) of a particular variable in the server
    environment. Alternatively, the condition
    can be expressed as arbitrary boolean expression. If the condition is not satisfied, the request
    will not be logged. References to HTTP headers  in the expression
    will not cause the header names to be added to the Vary header.
    

    
    Environment variables can be set on a per-request
    basis using the mod_setenvif
    and/or mod_rewrite modules. For
    example, if you want to record requests for all GIF
    images on your server in a separate logfile but not in your main
    log, you can use:
    

    
    SetEnvIf Request_URI \.gif$ gif-image
CustomLog "gif-requests.log" common env=gif-image
CustomLog "nongif-requests.log" common env=!gif-image
    


    
    Or, to reproduce the behavior of the old RefererIgnore
    directive, you might use the following:
    

    
    SetEnvIf Referer example\.com localreferer
CustomLog "referer.log" referer env=!localreferer
    



    

    top
    

    GlobalLog Directive
    

    

    Description:Sets filename and format of log file
    

    Syntax:GlobalLogfile|pipe
format|nickname
[env=[!]environment-variable|
expr=expression]
    

    Context:server config
    

    Status:Base
    

    Module:mod_log_config
    

    Compatibility:Available in Apache HTTP Server 2.4.19 and later
    

    

    
    The GlobalLog directive defines a log shared
       by the main server configuration and all defined virtual hosts.
    

    
    The GlobalLog directive is identical to
    the CustomLog directive, apart from the following
    differences:
    
    
      
       
    • GlobalLog is not valid in virtual host
            context.
      • 
       
    • GlobalLog is used by virtual hosts that
           define their own CustomLog, unlike a 
           globally specified CustomLog.
      • 
    
    


    

    top
    

    LogFormat Directive
    

    

    Description:Describes a format for use in a log file
    

    Syntax:LogFormat format|nickname
[nickname]
    

    Default:LogFormat "%h %l %u %t \"%r\" %>s %b"
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_log_config
    

    
    
    This directive specifies the format of the access log
    file.
    

    
    The LogFormat directive can take one of two
    forms. In the first form, where only one argument is specified,
    this directive sets the log format which will be used by logs
    specified in subsequent TransferLog
    directives. The single argument can specify an explicit
    format as discussed in the custom log
    formats section above. Alternatively, it can use a
    nickname to refer to a log format defined in a
    previous LogFormat directive as described
    below.
    

    
    The second form of the LogFormat
    directive associates an explicit format with a
    nickname. This nickname can then be used in
    subsequent LogFormat or
    CustomLog directives
    rather than repeating the entire format string. A
    LogFormat directive that defines a nickname
    does nothing else -- that is, it only
    defines the nickname, it doesn't actually apply the format and make
    it the default. Therefore, it will not affect subsequent
    TransferLog directives.
    In addition, LogFormat cannot use one nickname
    to define another nickname. Note that the nickname should not contain
    percent signs (%).
    

    
    Example
    LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost_common
    

    
    


    

    top
    

    TransferLog Directive
    

    

    Description:Specify location of a log file
    

    Syntax:TransferLog file|pipe
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_log_config
    

    
    
    This directive has exactly the same arguments and effect as
    the CustomLog
    directive, with the exception that it does not allow the log format
    to be specified explicitly or for conditional logging of requests.
    Instead, the log format is determined by the most recently specified
    LogFormat directive
    which does not define a nickname. Common Log Format is used if no
    other format has been specified.
    

    
    Example
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""
TransferLog logs/access_log

    Apache Module mod_heartbeat
    

    

    Available Languages:  en  |

    Description:Sends messages with server status to frontend proxy
    

    Status:Experimental
    

    Module Identifier:heartbeat_module
    

    Source File:mod_heartbeat
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    


     mod_heartbeat sends multicast messages to a mod_heartmonitor listener 
that advertises the servers current connection count.  Usually, mod_heartmonitor
will be running on a proxy server with mod_lbmethod_heartbeat loaded, which allows
ProxyPass to use the "heartbeat" lbmethod inside
of ProxyPass.
    

    
    mod_heartbeat itself is loaded on the origin server(s) that serve requests 
    through the proxy server(s).  

    

    
    
        To use mod_heartbeat,
        mod_status and mod_watchdog
        must be either a static modules or, if a dynamic module, must
        be loaded before mod_heartbeat.
    
    


    


    top
    

    

    Consuming mod_heartbeat Output
    
    
  
    
      Every 1 second, this module generates a single multicast UDP
      packet, containing the number of busy and idle workers.  The
      packet is a simple ASCII format, similar to GET query parameters
      in HTTP.
  
    
  

    An Example Packet
    
v=1&ready=75&busy=0

    

  
    
    Consumers should handle new variables besides busy and ready,
    separated by '&', being added in the future.

    Description:Generates directory indexes,
    automatically, similar to the Unix ls command or the
    Win32 dir shell command
    

    Status:Base
    

    Module Identifier:autoindex_module
    

    Source File:mod_autoindex.c
    

    Summary
    

      
    The index of a directory can come from one of two
      sources:
    

    
      
      
    • A file located in that directory, typically called
      index.html. The DirectoryIndex directive sets the
      name of the file or files to be used. This is controlled by
      mod_dir.
      • 

      
    • Otherwise, a listing generated by the server. The other
      directives control the format of this listing. The AddIcon, AddIconByEncoding and
      AddIconByType are
      used to set a list of icons to display for various file types;
      for each file listed, the first icon listed that matches the
      file is displayed. These are controlled by
      mod_autoindex.
      • 
    
    
    
    The two functions are separated so that you can completely
    remove (or replace) automatic index generation should you want
    to.
    

    
    Automatic index generation is enabled with using
    Options +Indexes. See the
    Options directive for
    more details.
    

    
    If the FancyIndexing option is given with the IndexOptions directive,
    the column headers are links that control the order of the
    display. If you select a header link, the listing will be
    regenerated, sorted by the values in that column. Selecting the
    same header repeatedly toggles between ascending and descending
    order. These column header links are suppressed with the
    IndexOptions directive's
    SuppressColumnSorting
    option.
    

    
    Note that when the display is sorted by "Size", it's the
    actual size of the files that's used, not the
    displayed value - so a 1010-byte file will always be displayed
    before a 1011-byte file (if in ascending order) even though
    they both are shown as "1K".

    Autoindex Request Query Arguments
    
    

    
    Various query string arguments are available to give the client
    some control over the ordering of the directory listing, as well as
    what files are listed. If you do not wish to give the client this
    control, the IndexOptions
    IgnoreClient option disables that functionality.
    

    
    The column sorting headers themselves are self-referencing
    hyperlinks that add the sort query options shown below. Any
    option below may be added to any request for the directory
    resource.
    

    
      
      
    • C=N sorts the directory by file name
      • 

      
    • C=M sorts the directory by last-modified
      date, then file name
      • 

      
    • C=S sorts the directory by size, then file
      name
      • 

      
    • C=D sorts the directory by description, then
      file name
      • 

      
    • O=A sorts the listing in Ascending
      Order
      • 

      
    • O=D sorts the listing in Descending
      Order
      • 

      
    • F=0 formats the listing as a simple list
      (not FancyIndexed)
      • 

      
    • F=1 formats the listing as a FancyIndexed
      list
      • 

      
    • F=2 formats the listing as an
      HTMLTable FancyIndexed list
      • 

      
    • V=0 disables version sorting
      • 

      
    • V=1 enables version sorting
      • 

      
    • P=pattern lists only files matching
      the given pattern
      • 
    
    

    
    Note that the 'P'attern query argument is tested
    after the usual IndexIgnore directives are processed,
    and all file names are still subjected to the same criteria as
    any other autoindex listing. The Query Arguments parser in
    mod_autoindex will stop abruptly when an unrecognized
    option is encountered. The Query Arguments must be well formed,
    according to the table above.
    

    
    The simple example below, which can be clipped and saved in
    a header.html file, illustrates these query options. Note that
    the unknown "X" argument, for the submit button, is listed last
    to assure the arguments are all parsed before mod_autoindex
    encounters the X=Go input.
    

    
    Example
    <form action="" method="get">
    Show me a <select name="F">
        <option value="0"> Plain list</option>
        <option value="1" selected="selected"> Fancy list</option>
        <option value="2"> Table list</option>
    </select>
    Sorted by <select name="C">
        <option value="N" selected="selected"> Name</option>
        <option value="M"> Date Modified</option>
        <option value="S"> Size</option>
        <option value="D"> Description</option>
    </select>
    <select name="O">
        <option value="A" selected="selected"> Ascending</option>
        <option value="D"> Descending</option>
    </select>
    <select name="V">
        <option value="0" selected="selected"> in Normal order</option>
        <option value="1"> in Version order</option>
    </select>
    Matching <input type="text" name="P" value="*" />
    <input type="submit" name="X" value="Go" />

    AddDescription Directive
    

    

    Description:Description to display for a file
    

    Syntax:AddDescription string file [file] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_autoindex
    

    
    
    This sets the description to display for a file, for
    FancyIndexing.
    File is a file extension, partial filename, wild-card
    expression or full filename for files to describe.
    String is enclosed in double quotes (").
    

    
    AddDescription "The planet Mars" mars.gif
AddDescription "My friend Marshall" friends/mars.gif
    


    
    The typical, default description field is 23 bytes wide. 6
    more bytes are added by the IndexOptions SuppressIcon option, 7 bytes are
    added by the IndexOptions SuppressSize option, and 19 bytes are
    added by the IndexOptions SuppressLastModified option.
    Therefore, the widest default the description column is ever
    assigned is 55 bytes.
    

    
    Since the File argument may be a partial file name,
    please remember that a too-short partial filename may match
    unintended files. For example, le.html will match the
    file le.html but will also match the file
    example.html. In the event that there may be ambiguity,
    use as complete a filename as you can, but keep in mind that the
    first match encountered will be used, and order your list of
    AddDescription directives accordingly.
    

    
    See the DescriptionWidth IndexOptions keyword for details on overriding the size
    of this column, or allowing descriptions of unlimited length.
    

    
    Caution
    
      
    Descriptive text defined with AddDescription
      may contain HTML markup, such as tags and character entities. If the
      width of the description column should happen to truncate a tagged
      element (such as cutting off the end of a bolded phrase), the
      results may affect the rest of the directory listing.
    
    
    

    
    Arguments with path information
    
      
    Absolute paths are not currently supported and do not match
      anything at runtime. Arguments with relative path information,
      which would normally only be used in htaccess context, are implicitly
      prefixed with '*/' to avoid matching partial directory names.

    is the text tag given for an icon for non-graphical browsers.
    

    
    Name is either ^^DIRECTORY^^ for directories,
    ^^BLANKICON^^ for blank lines (to format the list
    correctly), a file extension, a wildcard expression, a partial
    filename or a complete filename.
    

    
    ^^BLANKICON^^ is only used for formatting, and so
    is unnecessary if you're using IndexOptions
    HTMLTable.

    Override:Indexes
    

    Status:Base
    

    Module:mod_autoindex
    

    
    
    The HeaderName directive sets the name
    of the file that will be inserted at the top of the index
    listing. Filename is the name of the file to include.
    

    
    HeaderName HEADER.html
    


    
    
      
    Both HeaderName and ReadmeName now treat
      Filename as a URI path relative to the one used to
      access the directory being indexed. If Filename begins
      with a slash, it will be taken to be relative to the DocumentRoot.
    

      
    HeaderName /include/HEADER.html
    


      
    Filename must resolve to a document with a major
      content type of text/* (e.g.,
      text/html, text/plain, etc.). This means
      that filename may refer to a CGI script if the script's
      actual file type (as opposed to its output) is marked as
      text/html such as with a directive like:
    

      
    AddType text/html .cgi
    


      
    Content negotiation
      will be performed if Options
      MultiViews is in effect. If filename resolves
      to a static text/html document (not a CGI script) and
      either one of the options
      Includes or IncludesNOEXEC is enabled,
      the file will be processed for server-side includes (see the
      mod_include documentation).
    
    
    

    
    If the file specified by HeaderName contains
    the beginnings of an HTML document (<html>, <head>, etc.)
    then you will probably want to set IndexOptions
    +SuppressHTMLPreamble, so that these tags are not
    repeated.

      characters.
    

      
    -DescriptionWidth (or unset) allows
      mod_autoindex to calculate the best width.
    

      
    DescriptionWidth=n fixes the column width to
      n bytes wide.
    

      
    DescriptionWidth=* grows the column to the
      width necessary to accommodate the longest description
      string.

      See the section on AddDescription for dangers
      inherent in truncating descriptions.
    

      
    FancyIndexing
    

      
    This turns on fancy indexing of directories.
    

      
    FoldersFirst
    

      
    If this option is enabled, subdirectory listings will
      always appear first, followed by normal files in the
      directory. The listing is basically broken into two
      components, the files and the subdirectories, and each is
      sorted separately and then displayed subdirectories-first.
      For instance, if the sort order is descending by name, and
      FoldersFirst is enabled, subdirectory
      Zed will be listed before subdirectory
      Beta, which will be listed before normal files
      Gamma and Alpha.
      This option only has an effect if FancyIndexing
      is also enabled.
      
    

      
    HTMLTable
    

      
    This option with FancyIndexing constructs
      a simple table for the fancy directory listing.
      It is necessary for utf-8 enabled platforms or if file
      names or description text will alternate between
      left-to-right and right-to-left reading order.
    

      
    IconsAreLinks
    

      
    This makes the icons part of the anchor for the filename, for
      fancy indexing.
    

      
    IconHeight[=pixels]
    

      
    Presence of this option, when used with IconWidth,
      will cause the server to include height and
      width attributes in the img tag for the file
      icon. This allows browser to precalculate the page layout without having
      to wait until all the images have been loaded. If no value is given for
      the option, it defaults to the standard height of the icons supplied
      with the Apache httpd software.

      This option
      only has an effect if FancyIndexing is also enabled.

      
    

      
    IconWidth[=pixels]
    

      
    Presence of this option, when used with IconHeight,
      will cause the server to include height and
      width attributes in the img tag for
      the file icon. This allows browser to precalculate the page
      layout without having to wait until all the images have been
      loaded. If no value is given for the option, it defaults to
      the standard width of the icons supplied with the Apache httpd
      software.
    

      
    IgnoreCase
    

      
    If this option is enabled, names are sorted in a case-insensitive
      manner.  For instance, if the sort order is ascending by name, and
      IgnoreCase is enabled, file Zeta  will be listed after
      file alfa (Note: file GAMMA will always be listed before file gamma).
      
    

      
    IgnoreClient
    

      
    This option causes mod_autoindex to ignore all
      query variables from the client, including sort order (implies
      SuppressColumnSorting.)
    

      
    NameWidth=[n
               | *]
    

      
    The NameWidth keyword allows you to specify the width
      of the filename column in bytes.
    

      
    -NameWidth (or unset) allows mod_autoindex to calculate the best width, but only up
      to 20 bytes wide.
    

      
    NameWidth=n fixes the column width to
      n bytes wide.
    

      
    NameWidth=* grows the column to the necessary
      width.
    

      
    ScanHTMLTitles
    

      
    This enables the extraction of the title from HTML documents
      for fancy indexing. If the file does not have a description
      given by AddDescription
      then httpd will read the document for the value of the
      title element. This is CPU and disk intensive.
    

      
    ShowForbidden
    

      
    If specified, Apache httpd will show files normally hidden because
      the subrequest returned HTTP_UNAUTHORIZED or
      HTTP_FORBIDDEN
    

      
    SuppressColumnSorting
    

      
    If specified, Apache httpd will not make the column headings in a
      FancyIndexed directory listing into links for sorting. The
      default behavior is for them to be links; selecting the
      column heading will sort the directory listing by the values
      in that column. However, query string arguments which are appended
      to the URL will still be honored. That behavior is controlled by IndexOptions
      IgnoreClient.
    

      
    SuppressDescription
    

      
    This will suppress the file description in fancy indexing
      listings. By default, no file descriptions are defined, and
      so the use of this option will regain 23 characters of screen
      space to use for something else. See AddDescription for information about setting the file
      description. See also the DescriptionWidth
      index option to limit the size of the description column.

      This option
      only has an effect if FancyIndexing is also enabled.
      
    

      
    SuppressHTMLPreamble
    

      
    If the directory actually contains a file specified by the
      HeaderName
      directive, the module usually includes the contents of the file
      after a standard HTML preamble (<html>,
      <head>, et cetera). The
      SuppressHTMLPreamble option disables this behaviour,
      causing the module to start the display with the header file
      contents. The header file must contain appropriate HTML instructions
      in this case. If there is no header file, the preamble is generated
      as usual. If you also specify a ReadmeName, and if that file
      exists, The closing </body></html> tags are also
      omitted from the output, under the assumption that you'll likely
      put those closing tags in that file.
    

      
    SuppressIcon
    

      
    This will suppress the icon in fancy indexing listings.
      Combining both SuppressIcon and
      SuppressRules yields proper HTML 3.2 output, which
      by the final specification prohibits img and
      hr elements from the pre block (used to
      format FancyIndexed listings.)
    

      
    SuppressLastModified
    

      
    This will suppress the display of the last modification date,
      in fancy indexing listings.

      This option
      only has an effect if FancyIndexing is also enabled.
      
    

      
    SuppressRules
      
    

      
    This will suppress the horizontal rule lines (hr
      elements) in directory listings. Combining both SuppressIcon and
      SuppressRules yields proper HTML 3.2 output, which
      by the final specification prohibits img and
      hr elements from the pre block (used to
      format FancyIndexed listings.)

      This option
      only has an effect if FancyIndexing is also enabled.

      
    

      
    SuppressSize
    

      
    This will suppress the file size in fancy indexing listings.

      This option
      only has an effect if FancyIndexing is also enabled.
      
    

      
    TrackModified
    

      
    This returns the Last-Modified and ETag
      values for the listed directory in the HTTP header. It is only valid
      if the operating system and file system return appropriate stat()
      results. Some Unix systems do so, as do OS2's JFS and Win32's
      NTFS volumes. OS2 and Win32 FAT volumes, for example, do not.
      Once this feature is enabled, the client or proxy can track
      changes to the list of files when they perform a HEAD
      request. Note some operating systems correctly track new and
      removed files, but do not track changes for sizes or dates of
      the files within the directory. Changes to the size
      or date stamp of an existing file will not update the
      Last-Modified header on all Unix platforms.
      If this is a concern, leave this option disabled.
    

      
    Type=MIME content-type
    

      
    The Type keyword allows you to
      specify the MIME content-type of the generated page. The default
      is text/html.

      
    IndexOptions Type=text/plain
    

      
    

      
    UseOldDateFormat
      (Apache HTTP Server 2.4.26 and later)
    

      
    The date format used for the Last Modified field was 
      inadvertently changed to "%Y-%m-%d %H:%M" from 
      "%d-%b-%Y %H:%M" in 2.4.0. Setting this option 
      restores the date format from 2.2 and earlier.
    

      
    VersionSort
    

      
    The VersionSort keyword causes files containing
      version numbers to sort in a natural way. Strings are sorted as
      usual, except that substrings of digits in the name and
      description are compared according to their numeric value.

      
    Example:
    
        foo-1.7
    
        foo-1.7.2
    
        foo-1.7.12
    
        foo-1.8.2
    
        foo-1.8.2a
    
        foo-1.12
      
    

      
    If the number starts with a zero, then it is considered to
      be a fraction:
    

      
    
        foo-1.001
    
        foo-1.002
    
        foo-1.030
    
        foo-1.04
      
    
      
    

      
    XHTML
    

      
    The XHTML keyword forces mod_autoindex
      to emit XHTML 1.0 code instead of HTML 3.2.
      This option
      only has an effect if FancyIndexing is also enabled.
      
    

    
    


   
   
    Incremental IndexOptions
    
   
    
     
    Be aware of how multiple IndexOptions are
     handled.
    

     
      
     
    • Multiple IndexOptions directives for a
     single directory are now merged together. The result of:

     
      <Directory "/foo">
    IndexOptions HTMLTable
    IndexOptions SuppressColumnsorting
</Directory>
      


     
      will be the equivalent of
      

     
      IndexOptions HTMLTable SuppressColumnsorting
      

     
      • 

     
    • The addition of the incremental syntax (i.e., prefixing
     keywords with + or -).
      • 
     
    

     
    Whenever a '+' or '-' prefixed keyword is encountered, it
     is applied to the current IndexOptions
     settings (which may have been inherited from an upper-level
     directory). However, whenever an unprefixed keyword is processed, it
     clears all inherited options and any incremental settings encountered
     so far. Consider the following example:
    

     
    IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
IndexOptions +SuppressSize
    


     
    The net effect is equivalent to IndexOptions FancyIndexing
     +SuppressSize, because the unprefixed FancyIndexing
     discarded the incremental keywords before it, but allowed them to
     start accumulating again afterward.
    

     
    To unconditionally set the IndexOptions for
     a particular directory, clearing the inherited settings, specify
     keywords without any + or - prefixes.
    
   
    
   
    


    

    top
    

    IndexOrderDefault Directive
    

    

    Description:Sets the default ordering of the directory index
    

    Syntax:IndexOrderDefault Ascending|Descending
Name|Date|Size|Description
    

    Default:IndexOrderDefault Ascending Name
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_autoindex
    

    
    
    The IndexOrderDefault directive is used
    in combination with the FancyIndexing index option. By default, fancyindexed
    directory listings are displayed in ascending order by filename; the
    IndexOrderDefault allows you to change this
    initial display order.
    

    
    IndexOrderDefault takes two
    arguments. The first must be either Ascending or
    Descending, indicating the direction of the sort.
    The second argument must be one of the keywords Name,
    Date, Size, or Description,
    and identifies the primary key. The secondary key is
    always the ascending filename.
    

    
    You can, if desired, prevent the client from reordering the list
    by also adding the SuppressColumnSorting
    index option to remove the sort link from the top of the column,
    along with the IgnoreClient index
    option to prevent them from manually adding sort options to the
    query string in order to override your ordering preferences.

    IndexStyleSheet Directive
    

    

    Description:Adds a CSS stylesheet to the directory index
    

    Syntax:IndexStyleSheet url-path
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_autoindex
    

    
    
    The IndexStyleSheet directive sets the name of
    the file that will be used as the CSS for the index listing.
    
    
    
    IndexStyleSheet "/css/style.css"
    


    
    Using this directive in conjunction with IndexOptions
    HTMLTable adds a number of CSS classes to the resulting HTML.
    The entire table is given a CSS id of indexlist and the
    following classes are associated with the various parts of the
    listing:
    

    
    ClassDefinition
    

    tr.indexheadHeader row of listing
    

    th.indexcolicon and td.indexcolicon Icon column
    

    th.indexcolname and td.indexcolname File name column
    

    th.indexcollastmod and td.indexcollastmod Last modified column
    

    th.indexcolsize and td.indexcolsize File size column
    

    th.indexcoldesc and td.indexcoldesc Description column
    

    tr.breakrow Horizontal rule at the bottom of the table
    

    tr.odd and tr.even Alternating even and odd rows
    

    



    

    top
    

    ReadmeName Directive
    

    

    Description:Name of the file that will be inserted at the end
of the index listing
    

    Syntax:ReadmeName filename
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_autoindex
    

    
    
    The ReadmeName directive sets the name
    of the file that will be appended to the end of the index
    listing. Filename is the name of the file to include, and
    is taken to be relative to the location being indexed. If
    Filename begins with a slash, as in example 2, it will be taken to be
    relative to the DocumentRoot.
    
    

    
    # Example 1
ReadmeName FOOTER.html
    


    
    # Example 2
ReadmeName /include/FOOTER.html
    


    
    See also HeaderName, where this behavior is described in greater
    detail.

    Description:Basic HTTP authentication
    

    Status:Base
    

    Module Identifier:auth_basic_module
    

    Source File:mod_auth_basic.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module allows the use of HTTP Basic Authentication to
    restrict access by looking up users in the given providers.
    HTTP Digest Authentication is provided by
    mod_auth_digest.  This module should
    usually be combined with at least one authentication module
    such as mod_authn_file and one authorization
    module such as mod_authz_user.

    AuthBasicAuthoritative Directive
    

    

    Description:Sets whether authorization and authentication are passed to
lower level modules
    

    Syntax:AuthBasicAuthoritative On|Off
    

    Default:AuthBasicAuthoritative On
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_auth_basic
    

    
    
    Normally, each authorization module listed in AuthBasicProvider will attempt
    to verify the user, and if the user is not found in any provider,
    access will be denied. Setting the
    AuthBasicAuthoritative directive explicitly
    to Off allows for both authentication and
    authorization to be passed on to other non-provider-based modules
    if there is no userID or rule
    matching the supplied userID.  This should only be necessary when
    combining mod_auth_basic with third-party modules
    that are not configured with the AuthBasicProvider
    directive.  When using such modules, the order of processing
    is determined in the modules' source code and is not configurable.

    AuthBasicFake Directive
    

    

    Description:Fake basic authentication using the given expressions for
username and password
    

    Syntax:AuthBasicFake off|username [password]
    

    Default:none
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_auth_basic
    

    Compatibility:Apache HTTP Server 2.4.5 and later
    

    
    
    The username and password specified are combined into an
    Authorization header, which is passed to the server or service
    behind the webserver. Both the username and password fields are
    interpreted using the expression parser,
    which allows both the username and password to be set based on
    request parameters.
    

    
    If the password is not specified, the default value "password"
    will be used. To disable fake basic authentication for an URL
    space, specify "AuthBasicFake off".
    

    
    In this example, we pass a fixed username and password to a
    backend server.
    

    
    Fixed Example
    <Location "/demo">
    AuthBasicFake demo demopass
</Location>
    

    

    
    In this example, we pass the email address extracted from a client
    certificate, extending the functionality of the FakeBasicAuth option
    within the SSLOptions
    directive. Like the FakeBasicAuth option, the password is set to the
    fixed string "password".
    

    
    Certificate Example
    <Location "/secure">
    AuthBasicFake "%{SSL_CLIENT_S_DN_Email}"
</Location>
    

    

    
    Extending the above example, we generate a password by hashing the
    email address with a fixed passphrase, and passing the hash to the
    backend server. This can be used to gate into legacy systems that do
    not support client certificates.
    

    
    Password Example
    <Location "/secure">
    AuthBasicFake "%{SSL_CLIENT_S_DN_Email}" "%{sha1:passphrase-%{SSL_CLIENT_S_DN_Email}}"
</Location>
    

    

    
    Exclusion Example
    <Location "/public">
    AuthBasicFake off
</Location>

    AuthBasicProvider Directive
    

    

    Description:Sets the authentication provider(s) for this location
    

    Syntax:AuthBasicProvider provider-name
[provider-name] ...
    

    Default:AuthBasicProvider file
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_auth_basic
    

    
    
    The AuthBasicProvider directive sets
    which provider is used to authenticate the users for this location.
    The default file provider is implemented
    by the mod_authn_file module.  Make sure
    that the chosen provider module is present in the server.
    
    
    Example
    <Location "/secure">
    AuthType basic
    AuthName "private area"
    AuthBasicProvider  dbm
    AuthDBMType        SDBM
    AuthDBMUserFile    "/www/etc/dbmpasswd"
    Require            valid-user
</Location>
    

    
    
     Providers are queried in order until a provider finds a match
    for the requested username, at which point this sole provider will
    attempt to check the password.  A failure to verify the password does
    not result in control being passed on to subsequent providers.
    

    
    Providers are implemented by mod_authn_dbm,
    mod_authn_file, mod_authn_dbd,
    mod_authnz_ldap and mod_authn_socache.

    AuthBasicUseDigestAlgorithm Directive
    

    

    Description:Check passwords against the authentication providers as if
Digest Authentication was in force instead of Basic Authentication.

    Default:AuthBasicUseDigestAlgorithm Off

    Compatibility:Apache HTTP Server 2.4.7 and later
    

    
    
    Normally, when using Basic Authentication, the providers listed in
    AuthBasicProvider
    attempt to verify a user by checking their data stores for
    a matching username and associated password.  The stored passwords
    are usually encrypted, but not necessarily so; each provider may
    choose its own storage scheme for passwords.
    

    
    When using AuthDigestProvider and Digest
    Authentication, providers perform a similar check to find a matching
    username in their data stores.  However, unlike in the Basic
    Authentication case, the value associated with each stored username
    must be an encrypted string composed from the username, realm name,
    and password.  (See
    
    RFC 2617, Section 3.2.2.2 for more details on the format used
    for this encrypted string.)
    

    
    As a consequence of the difference in the stored values between
    Basic and Digest Authentication, converting from Digest
    Authentication to Basic Authentication generally requires that all
    users be assigned new passwords, as their existing passwords cannot
    be recovered from the password storage scheme imposed on those
    providers which support Digest Authentication.
    

    
    Setting the AuthBasicUseDigestAlgorithm directive
    to MD5 will cause the user's Basic Authentication password
    to be checked using the same encrypted format as for Digest
    Authentication.  First a string composed from the username, realm name,
    and password is hashed with MD5; then the username and this encrypted
    string are passed to the providers listed in
    AuthBasicProvider
    as if
    AuthType
    was set to Digest and Digest Authentication was in force.
    
    

    
    Through the use of AuthBasicUseDigestAlgorithm
    a site may switch from Digest to Basic Authentication without
    requiring users to be assigned new passwords.
    

    
    
      The inverse process of switching from Basic to Digest
      Authentication without assigning new passwords is generally
      not possible.  Only if the Basic Authentication passwords
      have been stored in plain text or with a reversible encryption
      scheme will it be possible to recover them and generate a
      new data store following the Digest Authentication password
      storage scheme.
    
    

    
    
      Only providers which support Digest Authentication will be able
      to authenticate users when AuthBasicUseDigestAlgorithm
      is set to MD5.  Use of other providers will result
      in an error response and the client will be denied access.

    Özet
    

    
    mod_status modülü, sunucu yöneticisinin, HTTP sunucusunun
      ne kadar başarılı olduğu hakkında bilgi edinmesini sağlar. Bilgiler,
      kolayca okunabilen bir HTML sayfası olarak sunulur ve o anki sunucu
      istatistiklerinden oluşur. Gerekirse sayfa kendiliğinden tazelenebilir
      (uyumlu bir tarayıcı gerekir). Diğer sayfa o anki sunucu durumunu makine
      tarafından okunabilen biçimde listeler.
    

    
    Sunulan bilgiler şunlardır:
    

    
      
      
    • İstekleri sunan çocuk süreç sayısı
      • 

      
    • Boştaki çocuk süreçlerin sayısı
      • 

      
    • Her çocuk sürecin durumu, çocuk sürecin işleme tabi tuttuğu istek
        sayısı ve sunduğu bayt sayısı (*)
      • 

      
    • Toplam erişim sayısı ve sunulan toplam bayt sayısı (*)
      • 

      
    • Sunucunun kaç kere başlatıldığı/yeniden başlatıldığı ve ne kadar
        zamandır çalışmakta olduğu
      • 

      
    • Saniyedeki ortalama istek sayısı, saniyedeki bayt sayısı ve istek
        başına ortalama bayt sayısı (*)
      • 

      
    • Birlikte tüm çocuk süreçler tarafınan toplamda ve her çocuk süreç
        tarafından ayrı ayrı kullanılan o anki işlemci zamanı yüzdesi (*)
      • 

      
    • O an işlem görmekte olan konakların ve isteklerin sayısı (*)
      • 
    
    

    
    "(*)" imli bilgiler sadece ExtendedStatus yönergesinin değeri On olduğu
      takdirde mevcuttur. 2.3.6 sürümünde, bu modulün yüklenmesi öntanımlı
      olarak ExtendedStatus yönergesinin
      değerini On yapacaktır.

    Durum Bilgisi Desteğinin Etkinleştirilmesi
    
    

    
    Durum raporları, sadece example.com alanından ve sadece tarayıcılar için
      etkin kılınmak istenirse httpd.conf dosyasına şu satırlar
      eklenebilir:
    


    <Location "/server-status">
    SetHandler server-status
    Require host example.com
</Location>
    


    
    Sunucu istatistiklerine tarayıcınızla erişmek isterseniz,
      http://sunucunuzun.ismi.buraya/server-status
      şeklinde bir istek yapabilirsiniz.
    

    top
    

    

    Sayfanın Tazelenmesi
    

    
    
    Tarayıcınız “tazeleme” yeteneğine sahipse durum sayfası düzenli
      aralıklarla güncellenecektir. Sayfanın N saniyede bir güncellenmesini
      isterseniz isteği şöyle yapabilirsiniz:
    
      http://sunucunuzun.ismi.buraya/server-status?refresh=N
    


    top
    

    

    Makine Tarafından Okunabilen Durum Dosyası
    

    
    
    Durum dosyasının makine tarafından okunabilen sürümüne
      http://sunucunuzun.ismi.buraya/server-status?auto
      şeklinde bir istek yaparak erişebilirsiniz. Bu, kendiliğinden çalıştığı
      takdirde yararlıdır; Apache HTTP Sunucusu kurulumunuzun
      /support dizininde bulunan log_server_status
      isimli Perl betiğine bakınız.
    

    
    Güvenlik
    
      mod_status sunucuya yüklendiği takdirde
       istatistikleri raporlama yeteneği dizin içi yapılandırma dosyaları
       (.htaccess gibi) dahil tüm yapılandırma dosyaları
       için kullanılabilir olacaktır. Bu durum güvenlik ile ilgili olarak
       siteniz için içinden çıkılması güç durumlara yol açabilir (çapanoğlu
       durumu).
    


    top
    

    

    Sorun gidermek için server-status kullanımı
    
    

    
    Sunucunuzun kullanılabilir tüm özkaynakları (işlemci veya bellek)
      sömürdüğü ve sizin de bu soruna hangi istemcilerin veya isteklerin yol
      açtığını saptamak istediğiniz durumda sorunu gidermek için başlangıç yeri
      olarak  server-status sayfası kullanılabilir.
    

    
    Önce ExtendedStatus yönergesine On
      atadığınızsan emin olun. Böylece her çocuk süreç veya evre için tüm istek
      ve istemci bilgilerini görebilirsiniz.
    

    
    (top veya benzeri bir süreç izleme aracı kullanarak) Artık
      kendi süreç listenize  ana zanlılar olan süreçleri bulmak için
      bakabilirsiniz. Sorunun çeşidine bağlı olarak top çıktısını
      işlemci kullanımına veya bellek kullanımına göre sıralatabilirsiniz.
    

  
    server-status sayfasını yeniden yükleyip bu süreç
    kimliklerine bakın. Böylece, bu süreçler tarafından hangi isteklerin hangi
    istemcilere sunulduğunu görebilirsiniz. İstekler kısa sürelerle görünürler,
    bu bakımdan iş üstünde yakalamak için çeşitli denemeler yapmanız
    gerekebilir.
    

    
    Bu işlem, yük sorununuzdan birinci derecede sorumlu istek türleri veya
      istemciler hakkında bir fikir verecektir. Çoğu durumda belli bir HTTP
      uygulamasının yanlış davrandığını veya belli bir istemcinin sitenize
      saldırmakta olduğunu farkedersiniz.

    Description:Documents html interprétés par le serveur (Server Side
Includes ou SSI)
    

    Statut:Base
    

    Identificateur de Module:include_module
    

    Fichier Source:mod_include.c
    

    Sommaire
    

    
    Ce module fournit un filtre qui va traiter les fichiers avant
    de les envoyer au client. Le traitement est contrôlé via des
    commentaires SGML spécialement formatés, aussi nommés
    éléments. Ces éléments permettent l'insertion
    conditionnelle de texte, l'inclusion d'autres fichiers ou
    programmes, ainsi que la définition et l'affichage de variables
    d'environnement.
    

    


    top
    

    

    Activation des SSI
    
    

    
    Les SSI sont implémentés par le filtre INCLUDES. Si des
    documents contenant des directives SSI possèdent une extension
    .shtml, les directives suivantes indiqueront à Apache de les
    interpréter et d'assigner le type MIME
    text/html au document obtenu :
    

    
    AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
    


    
    L'option suivante doit être définie pour les répertoires qui
    contiennent les fichiers shtml (en général dans une section
    <Directory>, mais
    cette option peut également être définie dans un fichier
    .htaccess si AllowOverride Options a été défini pour le
    répertoire considéré) :
    

    
    Options +Includes
    


    
    Pour des raisons de compatibilité ascendante, le gestionnaire  server-parsed
    peut aussi activer le filtre INCLUDES. Ainsi, Apache va activer le
    filtre INCLUDES pour tout document de type MIME
    text/x-server-parsed-html ou
    text/x-server-parsed-html3 (et le document obtenu aura
    pour type MIME text/html).
    

    
    Pour plus d'informations, voyez notre Tutoriel SSI.
    

    top
    

    

    PATH_INFO et SSI
    
    

    
    Les fichiers traités dans le cadre des SSI n'acceptent plus par
    défaut les requêtes avec PATH_INFO (les informations
    relatives au chemin en fin de requête). La directive AcceptPathInfo permet de configurer le
    serveur de façon à ce qu'il accepte ce genre de requête.
    

    top
    

    

    Eléments disponibles
    
    
    Le document est interprété comme un document HTML, avec des
    commandes spéciales incluses sous forme de commentaires SGML. La
    syntaxe d'une commande est la suivante : 
    

    
    
      <!--#élément attribut=valeur
      attribut=valeur ... -->
    
    

    
    Les valeurs sont souvent entourées de guillemets, mais on peut
    aussi utiliser des apostrophes (') ou des apostrophes
    inverses (`). De nombreuses commandes n'acceptent
    qu'une seule paire attribut-valeur. Notez que le terminateur de
    commentaire (-->) doit être précédé d'un espace afin
    d'être sûr qu'il ne soit pas considéré comme un élément de commande
    SSI. Notez aussi que le délimiteur de début <!--#
    est un élément de commande et ne doit donc pas contenir
    d'espace.
    

    
    La table suivante contient la liste des éléments autorisés :
    

    
    
    
    ElémentDescription

    printenv
        affiche toutes les variables disponibles
    
    
    set
        définit la valeur d'une variable
    
    
    

    
    Les éléments SSI peuvent être définis par d'autres modules que
    mod_include. À ce titre, l'élément exec est fourni par
    mod_cgi, et ne sera disponible que si ce module est
    chargé.
    

    
    L'élément comment
    
      
    Cette commande n'affiche aucune information. Elle n'a pour but que
      l'ajout de commentaires dans un fichier et ces commentaires ne sont pas
      affichés.
    

      
    Cette syntaxe est disponible à partir de la version 2.4.21 du serveur
      HTTP Apache.
    

      
    
      <!--#comment Blah Blah Blah -->
    
         or
    
      <!--#comment text="Blah Blah Blah" -->
      
    
     
    
    
    L'élément config
    
      
    Cette commande contrôle divers aspects de l'interprétation. Les
      attributs valides sont :
    

      
    
      
    echomsg (Versions 2.1 et supérieures
      d'Apache)
    
      
    La valeur est un message qui sera envoyé au client si
      l'élément echo tente
      d'afficher le contenu d'une variable non définie. Cet attribut
      l'emporte sur toute directive SSIUndefinedEcho.
    

      
    
        <!--#config echomsg="[Valeur non définie]" -->
      
    

      
    

      
    errmsg
    
      
    La valeur est un message qui sera envoyé au client si une
      erreur survient lors de l'interprétation du document. Cet attribut
      l'emporte sur toute directive SSIErrorMsg.
    

      
    
       <!--#config errmsg="[Zut, quelque chose s'est mal passé.]" -->
      
    

      
    

      
    sizefmt
    
      
    La valeur définit l'unité employée lors de l'affichage de la
      taille d'un fichier. Les valeurs possibles sont bytes
      pour une taille en octets, ou abbrev pour une taille
      en Ko ou Mo selon son importance ; par exemple, une taille de 1024
      octets sera affichée sous la forme "1K".
    

      
    
      <!--#config sizefmt="abbrev" -->
      
    

      
    

      
    timefmt
    
      
    La valeur est une chaîne que pourra utiliser la fonction de la
      bibliothèque standard strftime(3) lors de l'affichage
      des dates.
    

      
    
      <!--#config timefmt=""%R, %B %d, %Y"" -->
      
    

      
    
      
      
    
     

    
    L'élément echo
    
      
    Cette commande affiche le contenu d'une des variables include définies ci-dessous. Si
      la variable n'est pas définie, le résultat est déterminé par la
      valeur de la directive SSIUndefinedEcho. Le format d'affichage des dates est
      défini par l'attribut timefmt de la commande
      config.
    

      
    Attributs:
    

      
    
      
    var
    
      
    La valeur est le nom de la variable à afficher.
    

      
    decoding
    
      
    Spécifie si Apache doit effectuer un décodage dans la
      variable avant son traitement ultérieur. La valeur par défaut est
      none, et dans ce cas, aucun décodage n'est effectué.
      Si la valeur est url, un décodage de type URL sera
      effectué (il s'agit du codage de type %-encoding utilisé dans les
      URLs des liens, etc...). Si la valeur est urlencoded,
      c'est un décodage des éléments de type
      application/x-www-form-urlencode (que l'on trouve dans les chaînes
      de paramètres) qui sera effectué. Si la valeur est
      base64, un
      decodage de type base64 sera effectué, et si elle est
      entity, c'est un décodage des entités HTML qui sera
      effectué. Ce décodage est effectué avant tout codage ultérieur de
      la variable. Il est possible d'effectuer plusieurs décodages en
      spécifiant plusieurs valeurs séparées par des virgules. Les
      spécifications de décodages restent valables jusqu'au prochain
      attribut de décodage, ou la fin de l'élément.
    

      
    Pour être pris en compte, l'attribut de décodage
      doit précéder l'attribut var correspondant.
    
      
    

      
    encoding
    
      
    Spécifie la manière dont Apache va coder les caractères
      spéciaux que la variable contient avant leur affichage. S'il est
      défini à none, aucun codage ne sera effectué. S'il
      est défini à url, un codage de type URL sera effectué
      (aussi connu sous le nom de codage avec caractères % , il convient
      pour les URLS des liens, etc...). S'il est défini à
      urlencoded, c'est un codage compatible
      application/x-www-form-urlencoded qui sera effectué (à utiliser
      dans les chaînes de paramètres). S'il est défini à
      base64, c'est un encodage de type base64 qui sera
      effectué. Au début d'un élément
      echo, la valeur par défaut est définie à
      entity, ce qui correspond à un codage de type entité
      (codage qui convient pour un élément HTML de type bloc, comme le
      paragraphe d'un texte). Cette valeur par défaut peut être modifiée
      en ajoutant un attribut encoding, qui fera effet
      jusqu'à la définition d'un nouvel attribut encoding
      ou la fin de l'élément echo.
    

      
    Pour produire son effet, l'attribut encoding doit
      précéder l'attribut var concerné.
    

      
    
        Afin de prévenir les attaques de type cross-site scripting, il
	est recommandé de toujours encoder les données fournies
	par les utilisateurs.
      
    

      
    Example
    
        <!--#echo encoding="entity" var="QUERY_STRING" -->
      
    
      
    
      
    
     

    
    L'élément exec
    
      
    La commande exec exécute la commande shell ou le
      script spécifié. Elle nécessite le chargement du module
      mod_cgi. Si Options IncludesNOEXEC est
      définie, cette commande est désactivée. Les attributs disponibles
      sont :
    

      
    
      
    cgi
    
      
    La valeur spécifie un chemin URL vers le script CGI (encodé
      avec caractères %). Si le chemin ne commence pas par un slash (/),
      il est considéré comme relatif au document courant. Le document
      référencé par ce chemin est invoqué en tant que script CGI, même
      s'il n'est pas censé être reconnu comme tel par le serveur. Les
      scripts CGI doivent cependant être activés dans le répertoire qui
      contient les scripts (via la directive ScriptAlias ou l'Options ExecCGI).
    

      
    Le PATH_INFO et la chaîne d'arguments
      (QUERY_STRING) de la requête originale du client sont
      fournis au script CGI ; ils ne peuvent pas être spécifiés
      dans le chemin de l'URL. Le script disposera des variables include
      en plus de l'environnement standard CGI.
    

      
    Exemple
    
        <!--#exec cgi="/cgi-bin/exemple.cgi" -->
      
    

      
    Si, à la place d'un flux de sortie, le script renvoie un
      en-tête Location:, ce dernier sera traduit en ancrage
      HTML.
    

      
    L'élément include
      virtual doit être préféré à exec cgi. En
      particulier, si vous devez transmettre des arguments
      supplémentaires à un programme CGI en utilisant la chaîne
      d'arguments de la requête, c'est impossible avec exec
      cgi, mais vous pouvez y parvenir avec include
      virtual comme suit :
    

      
    
        <!--#include virtual="/cgi-bin/exemple.cgi?argument=valeur" -->
      
    
      
    

      
    cmd
    
      
    Le serveur va exécuter la commande fournie en utilisant
      /bin/sh. La commande dispose des variables include, en plus du jeu habituel
      de variables CGI.
    

      
    Il est toujours préférable d'utiliser #include virtual à la place de
      #exec cgi ou #exec cmd. #include
      virtual utilise le mécanisme standard des sous-requêtes
      d'Apache pour inclure des fichiers ou des scripts. Il a fait
      l'objet de tests plus approfondis et sa maintenance est mieux
      suivie.
    

      
    De plus, sur certaines plate-formes, comme Win32, et sous unix,
      si l'on utilise suexec, il est
      impossible de transmettre des arguments à une commande dans une
      directive exec, à moins d'insérer des espaces dans la
      commande. Ainsi, alors que ce qui suit fonctionnera sous unix avec
      une configuration sans suexec, l'effet produit ne sera pas celui
      désiré sous Win32, ou dans le cas de l'utilisation de suexec
      :
    

      
    
        <!--#exec cmd="perl /chemin/vers/script_perl arg1 arg2" -->
      
    
      
    
      
    
     

    
    L'élément fsize
    
      
    Cette commande permet d'afficher la taille du fichier spécifié
      en fonction des spécifications de format de sizefmt.
      Attributs :
    

      
    
      
    file
    
      
    La valeur est le chemin du fichier, relatif au répertoire
      contenant le document en cours d'interprétation.

      
    
        Ce fichier a une taille de <!--#fsize file="mod_include.html"
	--> octets.
    
    

    La valeur de file ne peut pas faire référence à un
    fichier situé à un niveau supérieur de l'arborescence du répertoire
    courant ou en dehors de la racine des documents ; il ne peut donc
    ni commencer par un slash, ni contenir la séquence de caractères
    ../. Si c'est le cas, le message d'erreur The
    given path was above the root path sera renvoyé.
      
    

      
    virtual
    
      
    La valeur est un chemin URL (codé avec caractères %). S'il ne
      commence pas par un slash (/), il est considéré comme relatif au
      document courant. Notez que cette commande n'affiche pas
      la taille de la sortie d'un programme CGI, mais la taille du
      programme CGI lui-même.
    
      
    

      
    
        Ce fichier a une taille de <!--#fsize
	virtual="/docs/mod/mod_include.html" --> octets.
    
    

      
    Notez que dans la plupart des cas, ces deux attributs sont
      identiques. Cependant, l'attribut file ne respecte
      pas les aliases URL-space.
    
     

    
    L'élément flastmod
    
      
    Cette commande permet d'afficher la date de dernière
      modification du fichier spécifié, en fonction des spécifications
      de format de timefmt. Les attributs sont les mêmes
      que ceux de la commande fsize.
    
     

    
    L'élément include
    
      
    Cette commande permet d'insérer le texte d'un autre document ou
      fichier dans le fichier en cours d'interprétation. Tout fichier
      inclus est soumis au contrôle d'accès habituel. Si Options IncludesNOEXEC
      est défini pour le répertoire contenant le fichier
      interprété, seuls les documents possèdant un
      type MIME de type texte
      (text/plain, text/html, etc...) seront
      inclus. Les scripts CGI, quant à eux, sont invoqués de manière
      habituelle en utilisant l'URL complète fournie avec la commande, y
      compris toute chaîne d'arguments éventuelle.
    

      
    Un attribut définit le chemin du document à inclure, et peut
      apparaître plusieurs fois dans l'élément à inclure ; en retour, pour
      chaque attribut fourni à la commande include, une inclusion est
      effectuée. Les attributs disponibles sont :
    

      
    
      
    file
    
      
    La valeur est un chemin relatif au répertoire contenant le
      fichier en cours d'interprétation. Elle ne peut ni contenir
      ../, ni être un chemin absolu. Ainsi, vous ne pouvez
      pas inclure de fichiers situés en dehors de l'arborescence du
      site web ou dans un niveau supérieur à celui du fichier courant
      dans cette arborescence. Il est toujours préférable d'utiliser
      l'attribut virtual.
    

      
    virtual
    
      
    La valeur est un chemin URL (codé avec caractères %). L'URL
      ne peut contenir qu'un chemin et une chaîne d'arguments
      éventuelle, à l'exclusion de tout protocole ou nom d'hôte. S'il ne
      commence pas par un slash (/), il est considéré comme relatif au
      document courant.
    

      
    Une URL est construite à partir de l'attribut, et la sortie que
      renverrait le serveur si l'URL était accédée par le client est
      incluse dans la sortie interprétée. Les inclusions de fichiers
      peuvent ainsi être imbriquées.
    

      
    Si l'URL spécifiée correspond à un programme CGI, le programme
      sera exécuté, et son flux de sortie inséré à la place de la
      directive dans le fichier interprété. Vous pouvez insérer une
      chaîne d'arguments dans une URL correspond à un programme CGI
      :
    

      
    
        <!--#include virtual="/cgi-bin/exemple.cgi?argument=valeur" -->
      
    

      
    include virtual doit être préféré à exec
      cgi pour inclure le flux de sortie d'un programme CGI dans
      un document HTML.
    

      
    Si la directive KeptBodySize est correctement
      définie et valide pour le fichier inclus, les tentatives de
      requêtes POST vers le document HTML qui inclut des fichiers seront
      transmises aux sous-requêtes en tant que requêtes POST
      elles-mêmes. Sans cette directive, toutes les sous-requêtes sont
      traitées en tant que requêtes GET.
    

      
    

      
    onerror
    
      
    La valeur est un chemin-URL (codé-%) qui est affiché si une
      tentative précédente d'inclure un fichier ou un attribut virtuel a
      échoué. Pour produire son effet, cet attribut doit être spécifié
      après le fichier ou les attributs virtuels concernés. Si la
      tentative d'inclure le chemin onerror échoue, ou si onerror n'est
      pas spécifié, c'est le message d'erreur par défaut qui sera
      inclus.
    

      
    
        # Exemple simple
    
        <!--#include virtual="/not-exist.html" onerror="/error.html" -->
      
    

      
    
        # Chemins onerror dédiés
    
        <!--#include virtual="/path-a.html" onerror="/error-a.html" virtual="/path-b.html" onerror="/error-b.html" -->
      
    

      
    
      
    
     

    
    L'élément printenv
    
      
    Cette commande affiche la liste en mode texte de toutes les variables et de
      leurs valeurs. Les caractères spéciaux sont encodés entity avant
      d'être affichés (se reporter à l'élément echo pour plus de détails). Cette
      commande ne comporte pas d'attributs.
    

      
    Exemple
    
        <pre>
          <!--#printenv -->
        </pre>
      
    
     

    
    L'élément set
    
      
    Cette commande permet de définir la valeur d'une variable. Les
      attributs sont :
    

      
    
      
    var
    
      
    Le nom de la variable à définir.
    

      
    value
    
      
    La valeur à affecter à la variable.
    
      
    decoding
    
      
    Spécifie si Apache doit effectuer un décodage dans la
      variable avant son traitement ultérieur. La valeur par défaut est
      none, et dans ce cas, aucun décodage n'est effectué.
      Si la valeur est url, urlencoded,
      base64 ou
      entity, c'est un décodage de type URL,
      application/x-www-form-urlencoded, base64 ou
      entité HTML qui sera respectivement effectué. Il est possible
      d'effectuer plusieurs décodages en
      spécifiant plusieurs valeurs séparées par des virgules. Les
      spécifications de décodages restent valables jusqu'au prochain
      attribut de décodage, ou la fin de l'élément. Pour être pris en
      compte, l'attribut de décodage
      doit précéder l'attribut var correspondant.
    
      
    

      
    encoding
    
      
    Spécifie la manière dont Apache va encoder les caractères
      spéciaux que la variable contient avant leur affichage. S'il est
      défini à none, aucun encodage ne sera effectué. Si la
      valeur est url, urlencoding,
      base64 ou
      entity, c'est un encodage de type URL,
      application/x-www-form-urlencoded, base64 ou
      entité HTML qui sera respectivement effectué. Il est possible de
      spécifier plusieurs types d'encodage en les séparant par des
      virgules. La spécification du type d'encodage fera effet
      jusqu'à la définition d'un nouvel attribut encoding
      ou la fin de l'élément. Pour produire son effet, l'attribut encoding doit
      précéder l'attribut var concerné. Les encodages sont
      effectués après les opérations de décodage.
    
      
    

      
    

      
    Exemple
    
        <!--#set var="category" value="help" -->
      
    
     

    top
    

    

    Variables include
    
    

    
    À l'instar des variables de l'environnement CGI standard, ces
    variables sont mises à la disposition de la commande
    echo, des opérateurs conditionnels if et
    elif, et de tout programme invoqué par le document.
    

    
    
      
    DATE_GMT
    
      
    La date GMT (Greenwich Mean Time) courante.
    

      
    DATE_LOCAL
    
      
    La date locale courante.
    

      
    DOCUMENT_ARGS
    
      
    Cette variable contient la chaîne de paramètres de la requête du
      document SSI actif, ou la chaîne vide si aucune chaîne de paramètres de
      requête n'est incluse. Pour les sous-requêtes invoquées par la directive
      SSI include, QUERY_STRING contiendra la chaîne
      de paramètres de la sous-requête et DOCUMENT_ARGS la chaîne
      de paramètres du document SSI (disponible à partir de la version 2.4.19 du
      serveur HTTP Apache).
    

      
    DOCUMENT_NAME
    
      
    Le nom de base du fichier demandé par l'utilisateur (sans son
      chemin).
    

      
    DOCUMENT_PATH_INFO
    
      
    La partie terminale du chemin du fichier. Voir la directive AcceptPathInfo pour plus d'informations à
      propos de PATH_INFO.
    

      
    DOCUMENT_URI
    
      
    Le chemin URL (caractères % décodés) du document demandé par
      l'utilisateur. Notez que dans le cas d'inclusions de fichiers
      imbriquées, il ne s'agit pas de l'URL du document
      courant. Notez également que si l'URL est modifiée en interne (par
      exemple via une directive alias ou directoryindex), c'est l'URL modifiée
      que contiendra la variable.
    

      
    LAST_MODIFIED
    
      
    La date de dernière modification du document demandé par
      l'utilisateur.
    

      
    QUERY_STRING_UNESCAPED
    
      
    Si une chaîne d'arguments est présente dans la requête pour le
      document SSI actif, elle sera affectée à
      cette variable, les caractères %-décodés, et éventuellement
      échappés pour qu'ils ne soient pas interprétés par le
      shell (les caractères spéciaux comme &,etc...
      sont précédés d'anti-slashes). Cette variable n'est pas définie si aucune
      chaîne d'arguments n'est présente. Utilisez DOCUMENT_ARGS si
      l'échappement des caractères du shell n'est pas souhaité.
    

      
    USER_NAME
    
      
    Le nom d'utilisateur du propriétaire du fichier.
    
    
    

    top
    

    

    Substitution de variable
    

    
    Une substitution de variable à l'intérieur d'une chaîne entre
    guillemets s'effectue dans la plupart des situations où cette
    dernière peut raisonablement constituer un argument d'une directive
    SSI. Sont concernées les directives config,
    exec, flastmod, fsize,
    include, echo, et set. Si la
    directive SSILegacyExprParser est définie à
    on, la substitution s'effectue aussi dans les arguments
    des opérateurs conditionnels. Vous pouvez insérer
    un signe dollar en tant que caractère littéral dans une chaîne en
    utilisant un anti-slash :
    

    
    
      <!--#set var="cur" value="\$test" -->
    
    

    
    Si une référence de variable doit être substituée au beau milieu
    d'une séquence de caractères qui pourrait être elle-même considérée
    comme un identifiant valide, l'ambiguïté peut être levée en
    entourant la référence d'accolades, à la manière du shell :
    

    
    
      <!--#set var="Zed" value="${REMOTE_HOST}_${REQUEST_METHOD}" -->
    
    

    
    Dans cet exemple, la variable Zed se verra affecter
    la valeur "X_Y" si REMOTE_HOST et
    REQUEST_METHOD contiennent respectivement
    "X" et "Y".
    


    top
    

    

    Eléments de contrôle d'inclusion conditionnelle
    
    

    
    Les éléments de base du contrôle d'inclusion conditionnelle sont
    :
    

    
    
      <!--#if expr="test_condition" -->
    
      <!--#elif expr="test_condition" -->
    
      <!--#else -->
    
      <!--#endif -->
    
    

    
    L'élément if fonctionne de la même manière que
    la directive if d'un langage de programmation. La condition est
    évaluée et si le résultat est vrai, le texte qui suit jusqu'au
    prochain élément elif, else ou
    endif sera inclus dans le flux de sortie.
    

    
    Les éléments elif ou else permettent
    d'insérer du texte dans le flux de sortie si
    test_condition s'est révélé faux. Ces éléments sont
    optionnels.
    

    
    L'élément endif termine le bloc de traitement
    conditionnel if et est obligatoire.
    

    
    test_condition est une expression booléenne qui
    emprunte la syntaxe ap_expr. La directive
    SSILegacyExprParser
    permet de modifier cette syntaxe pour la rendre compatible avec
    Apache HTTPD 2.2.x.
    

    
    Le jeu de variables SSI avec l'élément var sont
    exportées vers l'environnement de la requête et sont accessibles via
    la fonction reqenv. Pour faire simple, le nom de
    fonction v est aussi disponible dans le module
    mod_include.
    

    
    Dans l'exemple suivant, "depuis le réseau local"  sera affiché si
    l'adresse IP du client appartient au sous-réseau 10.0.0.0/8.
    

    
    
      <!--#if expr='-R "10.0.0.0/8"' -->
    
      
        depuis le réseau local
    
          
      <!--#else -->
    
      
        depuis ailleurs
    
          
      <!--#endif -->
    
    

    
    Dans l'exemple suivant, "foo vaut bar" sera affiché si la variable
    foo contient la valeur "bar".
    

    
    
      <!--#if expr='v("foo") = "bar"' -->
    
      
        foo vaut bar
    
          
      <!--#endif -->

    Syntaxe des expressions héritée
    
    

    
    Cette section décrit la syntaxe de l'élément #if
    expr dans le cas où la directive SSILegacyExprParser est définie à
    on.
    

    
    
      
    chaîne
    
      
    vrai si chaîne n'est pas vide
    

      
    -A string
    
      
    vrai si l'URL que contient la chaîne est accessible du
      point de vue de la configuration, faux sinon. Il
      s'avère utile lorsqu'un lien vers une URL doit être caché aux
      utilisateurs qui ne sont pas autorisés à voir cette URL. Notez que
      le test porte sur l'autorisation d'accès à l'URL, et non sur son
      existence.
    

      
    Exemple
    
        <!--#if expr="-A /prive" -->
    
        
          Cliquez <a href="/prive">ici</a> pour accéder aux
	  informations privées.
    
            
        <!--#endif -->
      
    
      
    

      
    chaîne1 = chaîne2
    
      chaîne1 == chaîne2
    
      chaîne1 != chaîne2
    

      
    Compare chaîne1 à chaîne2. Si
      chaîne2 est de la forme
      /chaîne2/, elle est traitée comme une
      expression rationnelle. Les expressions rationnelles sont
      implémentées par le moteur PCRE
      et possèdent la même syntaxe que celles de perl 5. Notez que ==
      n'est qu'un alias pour = et se comporte exactement de
      la même manière que ce dernier.
    

      
    Si vous faites une comparaison directe (= ou
      ==), vous pouvez extraire des parties de l'expression
      rationnelle. Les parties extraites sont stockées dans les
      variables spéciales $1 .. $9. L'ensemble
      de la chaîne correspondant à l'expression rationnelle est stocké
      dans la variable spéciale $0.
    

      
    Exemple
    
        <!--#if expr="$QUERY_STRING = /^sid=([a-zA-Z0-9]+)/" -->
    
        
          <!--#set var="session" value="$1" -->
    
            
        <!--#endif -->
      
    
      
    

      
    chaîne1 < chaîne2
    
       chaîne1 <= chaîne2
    
       chaîne1 > chaîne2
    
       chaîne1 >= chaîne2
    

      
    Compare chaîne1 à chaîne2. Notez que les
      chaînes sont comparées de manière littérale (en utilisant
      strcmp(3)). Ainsi, la chaîne "100" est inférieure à
      "20".
    

      
    ( test_condition )
    
      
    vrai si test_condition est vrai
    

      
    ! test_condition
    
      
    vrai si test_condition est faux
    

      
    test_condition1 &&
        test_condition2
    
      
    vrai si test_condition1 et
      test_condition2 sont tous les deux vrais
    

      
    test_condition1 ||
        test_condition2
    
      
    vrai si au moins un des tests test_condition1 ou
      test_condition2 est vrai
    
    
    

    
    "=" et "!=" ont une priorité supérieure
    à "&&" et "||". "!" a
    la priorité la plus haute. Ainsi, les deux directives suivantes sont
    équivalentes :
    

    
    
      <!--#if expr="$a = test1 && $b = test2" -->
    
      <!--#if expr="($a = test1) && ($b = test2)" -->
    
    

    
    Les opérateurs booléens && et
    || ont la même priorité. Ainsi, si vous voulez
    augmenter la priorité d'un de ces opérateurs, vous devez utiliser
    des parenthèses.
    

    
    Tout ce qui n'est pas reconnu comme variable ou opérateur est
    traité comme une chaîne. Les chaînes peuvent aussi être entourées
    d'apostrophes : 'chaîne'. Les chaînes sans apostrophe
    ne peuvent pas contenir d'espaces (espaces ou tabulations) car
    ceux-ci servent à séparer certains éléments comme les variables. Si
    plusieurs chaînes se trouvent dans une ligne, elles sont concaténées
    en utilisant des espaces. Ainsi,
    

    
    chaîne1    chaîne2 devient chaîne1 chaîne2
    
      
    
      et
    
      
    
      'chaîne1    chaîne2' devient chaîne1    chaîne2.
    

    
    Optimisation des expressions booléennes
    
      
    Si les expressions atteignent une complexité suffisante pour
      ralentir les traitements de manière significative, vous pouvez
      essayer de les optimiser en fonction des règles d'évaluation :
    
      
      
      
    • Les expressions sont évaluées de la gauche vers la droite
      • 
      
    • Les opérateurs booléens binaires (&& et
      ||) font l'objet d'une évaluation abrégée chaque fois
      que cela est possible. En d'autres termes, et selon la règle
      ci-dessus, mod_include évalue tout d'abord la
      partie gauche de l'expression. Si le résultat de l'évaluation de
      cette partie gauche suffit à déterminer le résultat final,
      l'évaluation s'arrête ici. Dans le cas contraire, la partie droite
      est évaluée, et le résultat final tient compte des résultats des
      évaluations des parties gauche et droite.
      • 
      
    • L'évaluation abrégée est désactivée tant qu'il reste des
      expressions régulières à traiter. Ces dernières doivent être
      évaluées afin de définir les variables correspondant aux
      références arrières ($1 .. $9).
      • 
      
    
      
    Si vous voulez déterminer la manière dont une expression est
      traitée, vous pouvez recompiler mod_include en
      utilisant l'option de compilation -DDEBUG_INCLUDE.
      Ceci a pour effet d'insérer, pour chaque expression interprétée,
      des informations étiquetées, l'arbre d'interprétation et la
      manière dont elle est évaluée au sein du flux de sortie envoyé au
      client.
    
    
    

    
    Slashes d'échappement dans les expressions
    rationnelles
    
     
    Tous les caractères slashes qui ne sont pas des séparateurs dans
     votre expression rationnelle doivent être échappés, et ceci sans
     tenir compte de leur signification du point de vue du moteur
     d'expressions rationnelles.

    Dans le cas général, un fichier filtré par
      mod_include peut contenir des éléments soit
      générés dynamiquement, soit éventuellement modifiés indépendemment
      du fichier original. En conséquence, il est demandé par défaut au
      serveur de ne pas générer d'en-tête ETag à la réponse
      en ajoutant no-etag aux informations de requête.
    

      
    Ce comportement peut être modifié via la directive
      SSIETag qui permet au serveur de générer un
      en-tête ETag. On peut aussi l'utiliser pour la mise
      en cache de la sortie. Notez qu'un serveur d'arrière-plan ou un
      générateur de contenu dynamique peut lui-même générer un en-tête
      ETag, en ignorant l'information no-etag,
      cet en-tête ETag étant transmis par
      mod_include sans tenir compte de la définition de
      la présente directive. La directive SSIETag
      peut prendre une des valeurs suivantes :
    

      
    

        
    off
    
        
    no-etag sera ajouté aux informations de
	requête, et il sera demandé au serveur de ne pas générer
	d'en-tête ETag. Lorsqu'un serveur ignore la valeur
	de no-etag et génère tout de même un en-tête
	ETag, ce dernier sera respecté.

    La directive SSILastModified permet de
      modifier ce comportement en faisant en sorte que l'en-tête
      Last-Modified soit respecté s'il est déjà présent, ou
      défini dans le cas contraire. On peut aussi l'utiliser pour la mise

    Note
    
      
    Il est recommandé de n'utiliser l'option full que dans le cas
      où vous êtes certain que le bit d'exécution du groupe est non
      positionné pour les scripts SSI qui pourraient effectuer l'#include d'un programme CGI ou bien produire des sorties
      différentes à chaque accès (ou seraient susceptibles d'être

    Açıklama:Ortam değişkenlerinin isteğin özelliklerine uygun olarak atanmasını sağlar

    Kaynak Dosyası:mod_setenvif.c
    

    Özet
    


    
    mod_setenvif modülü dahili ortam değişkenlerinin
      isteğin farklı bileşenlerinin belirttiğiniz düzenli ifade ile eşleşmesine
      bağlı olarak atanmasını mümkün kılar. Bu ortam değişkenleri sunucunun
      çeşitli kısımlarında yapılacak eylemlerin yanında CGI betiklerinde ve SSI
      sayfalarında kullanılabilir hale gelmelerine karar verilirken
      kullanılır.
    

    
    Yönergeler yapılandırma dosyasında yer aldıkları sıraya göre ele
      alınırlar. Böylece daha karmaşık dizilimler kullanılabilir, bu örnekteki
      tarayıcı Mozilla ise netscape ortam değişkeni atanmakta,
      MSIE ise atanmamaktadır.
    

    
    BrowserMatch ^Mozilla netscape
BrowserMatch MSIE !netscape
    


    
    mod_autoindex ile dizin listesi oluşturulması
      veya bir DirectoryIndex
      için yol aranması gibi bir dahili alt
      istek için sunucu yol araması yaparken isteklere özgü
      ortam değişkenleri alt istekler tarafından miras alınMAZ. Buna ek
      olarak, mod_setenvif modülünün devreye girdiği API
      fazlarından dolayı yapılan alt isteklerde
      SetEnvIf yönergeleri
      ayrı ayrı değerlendirilMEZ.

    BrowserMatch ve
      BrowserMatchNoCase yönergeleri SetEnvIf ve SetEnvIfNoCase yönergelerinin özel
      halleridir. Bu bakımda aşağıdaki iki satır aynı etkiye sahiptir:

    Modül:mod_setenvif
    

    
    
    SetEnvIf yönergesi ortam değişkenlerini isteğin
      özniteliklerine göre tanımlar. İlk bileşen olarak belirtilen
      öznitelik şu dört şeyden biri olabilir:
    

    
      
      
    1. Bir HTTP istek başlığı alanı (ayrıntılı bilgi için bak: RFC2616);
        örneğin: Host, User-Agent,
        Referer ve Accept-Language.  Bir düzenli
        ifade kullanılarak birden fazla istek başlığı  belirtilebilir.
      2. 

      
    2. İsteğin aşağıdaki bileşenlerinden biri:
        
        
          
      • Remote_Host - isteği yapan istemcinin konak ismi
            (varsa)
        • 

          
      • Remote_Addr -isteği yapan istemcinin IP adresi
        • 

          
      • Server_Addr - isteği alan sunucunun IP adresi
            (sadece 2.0.43 sonrası sürümler için)
        • 

          
      • Request_Method - kullanılan yöntemin ismi
            (GET, POST, vs.)
        • 

          
      • Request_Protocol - İsteğin yapıldığı protokolün
            ismi ve numarası ("HTTP/0.9", "HTTP/1.1" gibi)
        • 

          
      • Request_URI - HTTP istek satırında belirtilen
            özkaynak; genellikle sorgu dizgesi olmaksızın şema ve konak ismini
            içeren bir URL parçasıdır. Sorgu dizgeleriyle eşleşmeler hakkında
            ayrıntılı bilgi edinmek için mod_rewrite
            modülünün RewriteCond
            yönergesinin açıklamasına bakınız.
        • 
        
      
      
      3. 

      
    3. İstek ile evvelce ilişkilendirilmiş bir ortam değişkeninin ismi. Bu
        sayede önceki bir eşleşmenin sonucuna karşı yeni bir sınama yapma
        imkanı ortaya çıkar. Böyle bir sınama için sadece evvelce
        SetEnvIf[NoCase] yönergeleri ile yapılmış atamalardaki
        ortam değişkenleri kullanılabilir.  ‘Evvelce’ derken, sunucu genelinde
        veya bölüm içinde bu yönergeden önce yer alan
        SetEnvIf[NoCase] yönerge satırları kastedilmektedir.
        Ortam değişkenlerinin dikkate alınabilmesi için istek öznitelikleri
        arasında hiçbir eşleşme olmaması ve öznitelik
        olarak bir düzenli ifade belirtilmemiş olması gerekir.
      4. 
    
    

    
    İkinci bileşen (düzifd) bir düzenli ifadedir.  düzifd
      ile öznitelik eşleştiği takdirde yönergenin kalan
      bileşenleri değerlendirmeye alınır.
    

    
    Kalan bileşenler atanacak ortam değişkenlerinin isimleri ve isteğe
      bağlı olarak bunlara atanacak değerlerden oluşur. Bunlar şöyle
      belirtilebilir:

    Apache Module mod_speling

    Description:Attempts to correct mistaken URLs by ignoring
capitalization, or attempting to correct various minor
misspellings.
    

    Status:Extension
    

    Module Identifier:speling_module
    

    Source File:mod_speling.c
    

    Summary
    


    
    Requests to documents sometimes cannot be served by the core
    apache server because the request was misspelled or
    miscapitalized. This module addresses this problem by trying to
    find a matching document, even after all other modules gave up.
    It does its work by comparing each document name in the
    requested directory against the requested document name
    without regard to case, and allowing
    up to one misspelling (character insertion /
    omission / transposition or wrong character). A list is built
    with all document names which were matched using this
    strategy. Erroneous extension can also be fixed
    by this module.
    

    
    If, after scanning the directory,
    

    
      
      
    • no matching document was found, Apache will proceed as
      usual and return an error (404 - document not found).
      • 

      
    • only one document is found that "almost" matches the
      request, then it is returned in the form of a redirection
      response (301 - Moved Permanently).
      • 

      
    • more than one document with a close match was found, then
      the list of the matches is returned to the client, and the
      client can select the correct candidate (300 - Multiple
      Choices).
      •

    CheckBasenameMatch Directive
    

    

    Description:Also match files with differing file name extensions.
    

    Syntax:CheckBasenameMatch on|off
    

    Default:CheckBasenameMatch On
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Extension
    

    Module:mod_speling
    

    Compatibility:Available in httpd 2.4.50 and later
    

    
    
    When set, this directive extends the action of the spelling correction
    to the file name extension. For example a file foo.gif will
    match a request for foo or foo.jpg. This can be
    particularly useful in conjunction with
    MultiViews.

    CheckCaseOnly Directive
    

    

    Description:Limits the action of the speling module to case corrections
    

    Syntax:CheckCaseOnly on|off
    

    Default:CheckCaseOnly Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Extension
    

    Module:mod_speling
    

    
    
    When set, this directive limits the action of the spelling correction
    to lower/upper case changes.  Other potential corrections are not performed,
    except when CheckBasenameMatch is also set.

    CheckSpelling Directive
    

    

    Description:Enables the spelling
module
    

    Syntax:CheckSpelling on|off
    

    Default:CheckSpelling Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Options
    

    Status:Extension
    

    Module:mod_speling
    

    
    
    This directive enables or disables the spelling module. When
    enabled, keep in mind that
    

    
      
      
    • the directory scan which is necessary for the spelling
      correction will have an impact on the server's performance
      when many spelling corrections have to be performed at the
      same time.
      • 

      
    • the document trees should not contain sensitive files
      which could be matched inadvertently by a spelling
      "correction".
      • 

      
    • the module is unable to correct misspelled user names (as
      in http://my.host/~apahce/), just file names or
      directory names.
      • 

      
    • spelling corrections apply strictly to existing files, so
      a request for the <Location /status> may
      get incorrectly treated as the negotiated file
      "/stats.html".
      • 
    
    

    
    
    mod_speling should not be enabled in DAV
    enabled directories, because it will try to "spell fix" newly created
    resource names against existing filenames, e.g., when trying to upload
    a new document doc43.html it might redirect to an existing
    document doc34.html, which is not what was intended.

    AuthGroupFile ディレクティブは、
    証認に使用するユーザグループの一覧が格納されている、
    テキストファイルの名前を設定します。
    file-path はグループファイルへのパスです。
    絶対パスでなければ、
    ServerRoot
    からの相対パスとして扱われます。
    

    
    グループファイル各行は、グループ名、コロン、そして
    スペース区切りでそのメンバーのユーザ名を記述します。
    

    
    例:
    
      mygroup: bob joe anne
    
     

    
    大きなファイルを探索するのは、非常に効率が悪いという点に
    注意してください。そのような場合は、
    AuthDBMGroupFile
    の方がずっと良い性能を発揮します。
    

    
    セキュリティ
    
      
    AuthGroupFile は、
      ウェブサーバのドキュメントツリーの外側に
      保管するようにしてください。
      保護しようとしているディレクトリ以下には、置かないで下さい。
      そうしないとクライアントが AuthGroupFile を
      ダウンロードできてしまう可能性があります。

mod_usertrack - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Apache Module mod_usertrack
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:
Clickstream logging of user activity on a site

    

    Status:Extension
    

    Module Identifier:usertrack_module
    

    Source File:mod_usertrack.c
    

    Summary
    

    
    Provides tracking of a user through your website via browser
    cookies.
    

    


    top
    

    

    Logging
    


    
    mod_usertrack sets a cookie which can be logged
    via mod_log_config configurable logging formats:
    

    
    LogFormat "%{Apache}n %r %t" usertrack
CustomLog "logs/clickstream.log" usertrack
    



    

    top
    

    CookieDomain Directive
    

    

    Description:The domain to which the tracking cookie applies
    

    Syntax:CookieDomain domain
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    

    
    This directive controls the setting of the domain to which
    the tracking cookie applies. If not present, no domain is
    included in the cookie header field.
    

    
    The domain string must begin with a dot, and
    must include at least one embedded dot. That is,
    .example.com is legal, but www.example.com and
    .com are not.
    

    
    Most browsers in use today will not allow cookies to be set
    for a two-part top level domain, such as .co.uk,
    although such a domain ostensibly fulfills the requirements
    above.
    

    These domains are equivalent to top level domains such as
    .com, and allowing such cookies may be a security
    risk. Thus, if you are under a two-part top level domain, you
    should still use your actual domain, as you would with any other top
    level domain (for example .example.co.uk).
    
    

    
    CookieDomain .example.com
    



    

    top
    

    CookieExpires Directive
    

    

    Description:Expiry time for the tracking cookie
    

    Syntax:CookieExpires expiry-period
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    
    
    When used, this directive sets an expiry time on the cookie
    generated by the usertrack module. The expiry-period
    can be given either as a number of seconds, or in the format
    such as "2 weeks 3 days 7 hours". Valid denominations are:
    years, months, weeks, days, hours, minutes and seconds. If the expiry
    time is in any format other than one number indicating the
    number of seconds, it must be enclosed by double quotes.
    

    
    If this directive is not used, cookies last only for the
    current browser session.
    

    
    CookieExpires "3 weeks"
    



    

    top
    

    CookieHTTPOnly Directive
    

    

    Description:Adds the 'HTTPOnly' attribute to the cookie
    

    Syntax:CookieHTTPOnly on|off
    

    Default:CookieHTTPOnly off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    Compatibility:2.4.42 and later
    

    
    
    When set to 'ON', the 'HTTPOnly' cookie attribute is added to this 
    modules tracking cookie. This attribute instructs browsers to block javascript
    from reading the value of the cookie.
    


    

    top
    

    CookieName Directive
    

    

    Description:Name of the tracking cookie
    

    Syntax:CookieName token
    

    Default:CookieName Apache
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    
    
    This directive allows you to change the name of the cookie
    this module uses for its tracking purposes. By default the
    cookie is named "Apache".
    

    
    You must specify a valid cookie name; results are
    unpredictable if you use a name containing unusual characters.
    Valid characters include A-Z, a-z, 0-9, "_", and "-".
    

    
    CookieName clicktrack
    



    

    top
    

    CookieSameSite Directive
    

    

    Description:Adds the 'SameSite' attribute to the cookie
    

    Syntax:CookieSameSite None|Lax|Strict
    

    Default:unset
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    Compatibility:2.4.42 and later
    

    
    
    When set to 'None', 'Lax', or 'Strict', the 'SameSite' cookie attribute 
    is added to this modules tracking cookie with the corresponding value.  
    This attribute instructs browser on how to treat the cookie when it is 
    requested in a cross-site context.
    

     
    
        
    A value of 'None' sets 'SameSite=None', which is the most liberal setting. To 
        omit this attribute, omit the directive entirely.
    
    
    
  


    

    top
    

    CookieSecure Directive
    

    

    Description:Adds the 'Secure' attribute to the cookie
    

    Syntax:CookieSecure on|off
    

    Default:CookieSecure off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    Compatibility:2.4.42 and later
    

    
    
    When set to 'ON', the 'Secure' cookie attribute is added to this 
    modules tracking cookie. This attribute instructs browsers to only
    transmit the cookie over HTTPS.
    


    

    top
    

    CookieStyle Directive
    

    

    Description:Format of the cookie header field
    

    Syntax:CookieStyle
    Netscape|Cookie|Cookie2|RFC2109|RFC2965
    

    Default:CookieStyle Netscape
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    
    
    This directive controls the format of the cookie header
    field. The three formats allowed are:
    

    
      
      
    • Netscape, which is the original but now deprecated
      syntax. This is the default, and the syntax Apache has
      historically used.
      • 

      
    • Cookie or RFC2109, which is the syntax that
      superseded the Netscape syntax.
      • 

      
    • Cookie2 or RFC2965, which is the most
      current cookie syntax.
      • 
    
    

    
    Not all clients can understand all of these formats, but you
    should use the newest one that is generally acceptable to your
    users' browsers. At the time of writing, most browsers support all
    three of these formats, with Cookie2 being the
    preferred format.
    

    
    CookieStyle Cookie2
    



    

    top
    

    CookieTracking Directive
    

    

    Description:Enables tracking cookie
    

    Syntax:CookieTracking on|off
    

    Default:CookieTracking off
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension
    

    Module:mod_usertrack
    

    
    
    When mod_usertrack is loaded, and
    CookieTracking on is set, Apache will send a
    user-tracking cookie for all new requests. This directive can
    be used to turn this behavior on or off on a per-server or
    per-directory basis. By default, enabling
    mod_usertrack will not
    activate cookies. 
    

    
    CookieTracking on

    概要
    

    
    このモジュールには二つのディレクティブがあります。Action
    ディレクティブは特定の MIME タイプのファイルをリクエストされた場合に
    CGI スクリプトが実行されるようにします。Script
    ディレクティブはリクエストで特定のメソッドが使用されたときに CGI
    スクリプトが実行されるようにします。
    これはファイルを処理するスクリプトの実行をずっと簡単にします。

    このディレクティブは action-type
    がリクエストされたときに cgi-script
    が実行されるという動作を追加します。cgi-script は
    ScriptAlias や
    AddHandler によって
    CGI スクリプトに設定されたリソースへの URL-path です。
    Action-type には
    handler か MIME
    コンテントタイプを指定できます。リクエストされたドキュメントの URL
    とファイルのパスは標準 CGI 環境変数 PATH_INFO と
    PATH_TRANSLATED を使って伝えられます。
    特定のリクエストに対して使用されるハンドラへは、
    REDIRECT_HANDLER 変数を使って渡せます。

      Action image/gif /cgi-bin/images.cgi
    
      
    
      # Files of a particular file extension
    
      AddHandler my-file-type .xyz
    
      Action my-file-type /cgi-bin/program.cgi
    
    
    

    
    最初の例では、MIME コンテントタイプが image/gif
    のファイルへのリクエストは、指定したスクリプト
    /cgi-bin/images.cgi で処理されます。
    

    
    2 番目の例では、拡張子が .xyz 
    のファイルへのリクエストは、指定したスクリプト
    /cgi-bin/program.cgi で処理されます。
    

    
    オプションの virtual 修飾子を使用すると、
    リクエストされたファイルが実際に存在するかどうかを検査しないようにできます。
    これは例えば、Action ディレクティブをバーチャルな
    Location に使用したい、といった場合に便利です。
    

    
    例
    
      <Location /news>
    
      
        SetHandler news-handler
    
        Action news-handler /cgi-bin/news.cgi virtual
    
          
      </Location>

    Script ディレクティブ
    

    

    説明:特定のリクエストメソッドに対して CGI スクリプトを
実行するように設定
    

    構文:Script method cgi-script
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ
    

    ステータス:Base
    

    モジュール:mod_actions
    

    
    
    このディレクティブは method
    というメソッドを使ってリクエストが行なわれたときに
    cgi-script を実行するという動作を追加します。
    cgi-script は
    ScriptAlias や
    AddHandler によって
    CGI スクリプトに設定されたリソースへの URL-path です。
    リクエストされたドキュメントの URL とファイルのパスは標準 CGI
    環境変数 PATH_INFO と PATH_TRANSLATED
    を使って伝えられます。
    

    
    
      任意のメソッド名を使用することができます。
      メソッド名は大文字小文字を区別します。ですから、
      Script PUT と Script put
      はまったく違った効果になります。
    
    

    
    Script コマンドはデフォルトの動作を
    追加するだけであることに
    注意してください。もし CGI スクリプトが呼ばれたり、リクエストされた
    メソッドを内部で扱うことのできる他のリソースがあれば、それが行なわれます。
    GET メソッドの Script は問合せ
    引数がある場合にのみ
    (たとえば、foo.html?hi) 呼ばれるということにも注意してください。
    そうでない場合は、リクエストは通常通り処理されます。
    

    
    例
    
      # For <ISINDEX>-style searching
    
      Script GET /cgi-bin/search
    
      
    
      # A CGI PUT handler
    
      Script PUT /~bob/put.cgi

    Description:Fournit des points d'entrée Lua dans différentes parties du
traitement des requêtes httpd
    

    Statut:Extension
    

    Identificateur de Module:lua_module
    

    Fichier Source:mod_lua.c
    

    Compatibilité:versions 2.3 et supérieures
    

    Sommaire
    


    Ce module permet d'ajouter au serveur des extensions sous forme de
scripts écrits dans le langage de programmation Lua.
mod_lua fournit de nombreuses extensions
(hooks) disponibles avec les modules natifs du serveur HTTP Apache,
comme les associations de requêtes à des fichiers, la génération de
réponses dynamiques, le contrôle d'accès, l'authentification et
l'autorisation.
    


    Vous trouverez davantage d'informations à propos du langage de
programmation Lua sur le site web de
Lua.
    


    Avertissement
    

    Ce module possède une grande capacité d'action sur le fonctrionnement
de httpd, ce qui lui confère une grande puissance, mais peut aussi
induire un risque de sécurité. Il est déconseillé d'utiliser ce module
sur un serveur partagé avec des utilisateurs auxquels vous ne pouvez pas
accorder une confiance absolue, car il peut permettre de modifier le
fonctionnement interne de httpd.

    Configuration de base
    


    La directive de base pour le chargement du module est
    


    LoadModule lua_module modules/mod_lua.so
    



    
mod_lua fournit un gestionnaire nommé
lua-script qui peut être utilisé avec une directive
AddHandler ou SetHandler :
    


    <Files "*.lua">
    SetHandler lua-script
</Files>
    



    
Ceci aura pour effet de faire traiter les requêtes pour les fichiers
dont l'extension est .lua par mod_lua en
invoquant cette fonction de gestion de fichier.

    


    Pour plus de détails, voir la directive
LuaMapHandler.
 
    

    top
    

    

    Ecrire des gestionnaires
    

    Dans l'API du serveur HTTP Apache, un gestionnaire est une sorte de
point d'accroche (hook) spécifique responsable de la génération de la
réponse. mod_proxy, mod_cgi et
mod_status sont des exemples de modules comportant un
gestionnaire.
    


    mod_lua cherche toujours à invoquer une fonction Lua pour le
gestionnaire, plutôt que de simplement évaluer le corps d'un script dans
le style de CGI. Une fonction de gestionnaire se présente comme suit :
    



    example.lua
    
-- exemple de gestionnaire

require "string"

--[[
     Il s'agit du nom de méthode par défaut pour les gestionnaires Lua ;
     voir les noms de fonctions optionnels dans la directive
     LuaMapHandler pour choisir un point d'entrée différent.
--]]
function handle(r)
    r.content_type = "text/plain"

    if r.method == 'GET' then
    	r:puts("Hello Lua World!\n")
        for k, v in pairs( r:parseargs() ) do
            r:puts( string.format("%s: %s\n", k, v) )
        end
    elseif r.method == 'POST' then
    	r:puts("Hello Lua World!\n")
        for k, v in pairs( r:parsebody() ) do
            r:puts( string.format("%s: %s\n", k, v) )
        end
    else
    elseif r.method == 'PUT' then
-- message d'erreur personnalisé
        r:puts("Unsupported HTTP method " .. r.method)
	r.status = 405
        return apache2.OK
    else
-- message d'erreur ErrorDocument
        return 501
    end
    return apache2.OK
end
    



    
Ce gestionnaire se contente d'afficher les arguments codés d'un uri ou
d'un formulaire dans un page au format texte.

    


    
Cela signifie que vous pouvez (et êtes encouragé à) avoir plusieurs
gestionnaires (ou points d'entrée, ou filtres) dans le même script.

    Ecriture de fournisseurs d'autorisation
    



    mod_authz_core fournit une interface d'autorisation
de haut niveau bien plus facile à utiliser que dans les hooks
correspondants. Le premier argument de la directive Require permet de spécifier le
fournisseur d'autorisation à utiliser. Pour chaque directive Require,
mod_authz_core appellera le fournisseur d'autorisation
spécifié, le reste de la ligne constituant les paramètres. Le
fournisseur considéré va alors vérifier les autorisations et fournir le
résultat dans une valeur de retour.
    


    En général, le fournisseur authz est appelé avant l'authentification.
S'il doit connaître le nom d'utilisateur authentifié (ou si
l'utilisateur est appelé à être authentifié), le fournisseur doit
renvoyer apache2.AUTHZ_DENIED_NO_USER, ce qui va
déclancher le processus d'authentification et un deuxième appel du
fournisseur authz.
    


    La fonction du fournisseur authz ci-dessous accepte deux arguments,
une adresse IP et un nom d'utilisateur. Elle autorise l'accès dans le
cas où la requête provient de l'adresse IP spécifiée, ou si
l'utilisateur authentifié correspond au second argument :
    


    authz_provider.lua
    

require 'apache2'

function authz_check_foo(r, ip, user)
    if r.useragent_ip == ip then
        return apache2.AUTHZ_GRANTED
    elseif r.user == nil then
        return apache2.AUTHZ_DENIED_NO_USER
    elseif r.user == user then
        return apache2.AUTHZ_GRANTED
    else
        return apache2.AUTHZ_DENIED
    end
end
    



    La configuration suivante enregistre cette fonction en tant que
fournisseur foo, et la configure por l'URL / :
    

    LuaAuthzProvider foo authz_provider.lua authz_check_foo
<Location "/">
  Require foo 10.1.2.3 john_doe
</Location>

    Ecriture de fonctions d'accroche
(hooks)
    


    Les fonctions d'accroche déterminent la manière dont les modules (et
les scripts Lua) participent au traitement des requêtes. Chaque type
d'accroche proposé par le serveur a un rôle spécifique, comme
l'association de requêtes au système de fichiers, le contrôle d'accès,
ou la définition de types MIME : 
    


    
        Phase d'accroche
        Directive mod_lua
        Description
    
    

    
        Gestionnaire rapide
        LuaQuickHandler
        Il s'agit de la première accroche appelée lorsqu'une requête
	a été associée à un serveur ou un serveur virtuel.
    
    

    
        Phase de pré-traduction
        LuaHookPreTranslateName
        Cette phase traduit l'URI de la requête en nom de fichier sur le
	système avant la phase de décodage. Des modules comme
	mod_proxy peuvent agir au cours de cette phase.
    
    

     
        Phase de traduction
        LuaHookTranslateName
        Cette phase traduit l'URI de la requête en nom de fichier
	sur le système. Ce sont des modules comme
	mod_alias et mod_rewrite qui
	interviennent au cours de cette phase.
    
    

    
        Choix du lieu de stockage de la ressource
        LuaHookMapToStorage
        Cette phase définit le lieu de stockage de la ressource :
	physique, en cache ou externe/mandaté. Elle est assurée par les
	modules de mandat ou de mise en cache.
    
    

    
        Autorisation d'accès
        LuaHookAccessChecker
        Cette phase vérifie si un client a l'autorisation d'accès à
	la ressource. Elle s'exécute avant l'authentification de
	l'utisateur ; il faut donc être prudent.
        
    
    

    
        Vérification de l'identifiant utilisateur
        LuaHookCheckUserID
        Cette phase vérifie l'identifiant de l'utilisateur ayant
	fait l'objet d'une négociation.
    
    

    
        Vérification de l'autorisation d'accès
        LuaHookAuthChecker
	ou
            LuaAuthzProvider
        Cette phase vérifie l'autorisation d'accès d'un utilisateur
	en fonction des ses paramètres de connexion, comme
	l'identifiant, le certificat, etc...
        
    
    

    
        Vérification du type de la ressource
        LuaHookTypeChecker
        Cette phase assigne un type de contenu et un gestionnaire à
	la ressource.
    
    

    
        Derniers réglages
        LuaHookFixups
        C'est la dernière phase avant l'activation des gestionnaires
	de contenu. Toute modification de dernière minute à la requête
	doit être effectuée ici.
    
    

    
        Gestionnaire de contenu
        fichiers fx. .lua ou directive LuaMapHandler
        C'est durant cette phase que le contenu est traité. Les
	fichiers sont lus, interprétés, certains sont exécutés, et le
	résultat obtenu est envoyé au client.
    
    

    
        Journalisation
        LuaHookLog
        Lorsqu'une requête a été traitée, plusieurs phases de
	journalisation interviennent, et enregistrent leurs résultats
	dans les fichiers d'erreur ou d'accès. Mod_lua peut
	s'intercaler au départ de ce processus et ainsi contrôler la
	journalisation.
    
    

    


    Les fonctions d'accroche reçoivent l'objet de la requête comme seul
argument (sauf LuaAuthzProvider qui reçoit aussi des arguments en
provenance de la directive Require). Elles peuvent renvoyer une valeur,
selon la fonction, mais il s'agit en général d'un
code d'état HTTP ou des valeurs OK, DONE, ou DECLINED,
que vous pouvez écrire dans Lua sous la forme apache2.OK,
apache2.DONE, ou apache2.DECLINED.
    



    translate_name.lua
    
-- exemple d'accroche qui réécrit un URI en chemin du système de fichiers.

require 'apache2'

function translate_name(r)
    if r.uri == "/translate-name" then
        r.filename = r.document_root .. "/find_me.txt"
        return apache2.OK
    end
    -- on ne gère pas cette URL et on donne sa chance à un autre module
    return apache2.DECLINED
end
    




    translate_name2.lua
    
--[[ exemple d'accroche qui réécrit un URI vers un autre URI. Il renvoie
	un apache2.DECLINED pour permettre à un autre interpréteur d'URL de
	travailler sur la substitution, y compris l'accroche translate_name
	de base dont les tables de correspondances se basent sur DocumentRoot.

     Note: utilisez le drapeau early/late de la directive pour
     l'exécuter avant ou après mod_alias.
--]]

require 'apache2'

function translate_name(r)
    if r.uri == "/translate-name" then
        r.uri = "/find_me.txt"
        return apache2.DECLINED
    end
    return apache2.DECLINED
end

    Structures de données
    


    

    request_rec
    
        
    
        
    request_rec est considérée en tant que donnée utilisateur.
	Elle possède une métatable qui vous permet d'accomplir des
	choses intéressantes. Pour la plus grande partie, elle possède
	les mêmes champs que la structure request_rec, la
	plupart d'entre eux étant accessibles en lecture et écriture (le
	contenu des champs de la table peut être modifié, mais les
	champs eux-mêmes ne peuvent pas être établis en tant que tables
	distinctes).

    Modification de contenu avec les filtres lua
    
    
    
    
    Les fonctions de filtrage implémentées via les directives LuaInputFilter ou LuaOutputFilter sont conçues comme des
    fonctions de 3ème phase non blocantes utilisant des sous-routines
    pour suspendre et reprendre l'exécution d'une fonction lorsque des
    paquets de données sont envoyés à la chaîne de filtrage. La
    structure de base d'une telle fonction est :
    
    
    
    function filter(r)
    -- Nous indiquons tout d'abord que nous sommes prêts à recevoir des
    -- blocs de données.
    -- Avant ceci, nous pouvons définir notre environnement, tester
    -- certaines conditions, et, si nous le jugeons nécessaire, refuser le
    -- filtrage d'une requête :
    if something_bad then
        return -- Le filtrage est sauté
    end
    -- Sans se préoccuper des données que nous devons éventuellement ajouter, un arrêt est réalisé ici.
    -- Noter que les filtres de sortie sont les seuls capables d'ajouter des éléments au début des données.
    -- Les filtres en entrée peuvent ajouter des éléments à la fin des données au stade final.

    coroutine.yield([optional header to be prepended to the content])

    -- Après cet arrêt, nous allons recevoir d'autres blocs de données, un par un ;
    -- nous pouvons les traiter comme il nous plaît et procéder à la réponse.
    -- Ces blocs sont conservés dans la variable globale 'bucket', nous réalisons donc
    -- une boucle pour vérifier que 'bucket' n'est pas vide :
    while bucket ~= nil do
        local output = mangle(bucket) -- Do some stuff to the content
        coroutine.yield(output) -- Return our new content to the filter chain
    end

    -- Une fois les blocs de données épuisés, 'bucket' est positionné à une valeur vide ('nil'),
    -- ce qui va nous faire sortir de cette boucle et nous amener à l'étape suivante.
    -- On peut ajouter ce qu'on veut à la fin des données à cette étape, qui constitue le dernier
    -- arrêt. Les filtres d'entrée comme de sortie peuvent servir à ajouter des éléments à la fin
    --  des données à cette étape.

    Connectivité aux bases de données
    
    
    
    Mod_lua implémente une fonctionnalité basique de connexion aux
bases de données permettant d'envoyer des requêtes ou d'exécuter des
commandes auprès des moteurs de base de données les plus courants
(mySQL, PostgreSQL, FreeTDS, ODBC, SQLite, Oracle), ainsi que mod_dbd.
    
    
    
    L'exemple suivant montre comment se connecter à une base de
données et extraire des informations d'une table :
    
    
    function handle(r)
    -- connexion à la base de données
    local database, err = r:dbacquire("mysql", "server=localhost,user=someuser,pass=somepass,dbname=mydb")
    if not err then
        -- Sélection de certaines informations
        local results, err = database:select(r, "SELECT `name`, `age` FROM `people` WHERE 1")
        if not err then
            local rows = results(0) -- extrait tous les enregistrements en mode synchrone
            for k, row in pairs(rows) do
                r:puts( string.format("Name: %s, Age: %s<br/>", row[1], row[2]) )
            end
        else
            r:puts("Database query error: " .. err)
        end
        database:close()
    else
        r:puts("Connexion à la base de données impossible : " .. err)
    end
end
    

    
    
    Pour utiliser mod_dbd, spécifiez
mod_dbd comme type de base de données, ou laissez le champ
vide :
    
    
    
    local database = r:dbacquire("mod_dbd")
    

    
    L'objet database et ses méthodes
    
        
        
    L'objet database renvoyé par dbacquire possède
les méthodes suivantes :
    
        
    Sélection normale et requête vers une base de données
:
    
    
    -- Exécution d'une requête et renvoie du nombre d'enregistrements
affectés :
local affected, errmsg = database:query(r, "DELETE FROM `tbl` WHERE 1")

-- Exécution d'une requête et renvoie du résultat qui peut être utilisé
en mode synchrone ou asynchrone :
local result, errmsg = database:select(r, "SELECT * FROM `people` WHERE 1")
    

        
    Utilisation de requêtes préparées (recommandé) :
    
    
    -- Création et exécution d'une requête préparée :
local statement, errmsg = database:prepare(r, "DELETE FROM `tbl` WHERE `age` > %u")
if not errmsg then
    local result, errmsg = statement:query(20) -- exécute la requête pour age > 20
end

-- Extrait une requête préparée depuis une directive DBDPrepareSQL :
local statement, errmsg = database:prepared(r, "someTag")
if not errmsg then
    local result, errmsg = statement:select("John Doe", 123) -- injecte les valeurs "John Doe" et 123 dans la requête
end
    

        
    Echappement de valeurs, fermeture de la base données,
etc...
    
    
    -- Echappe une valeur pour pouvoir l'utiliser dans une requête :
local escaped = database:escape(r, [["'|blabla]])

-- Ferme une base de données et libère les liens vers cette dernière :
database:close()

-- Vérifie si une connexion à une base de données est en service et
opérationnelle :
local connected = database:active()
    

    
    
    Travail avec les jeux d'enregistrements renvoyés par les requêtes
    
    
    
    Les jeux d'enregistrements renvoyés par db:select ou par des
requêtes préparées créées par db:prepare permettent de
sélectionner des enregistrements en mode synchrone ou
asynchrone, selon le nombre d'enregistrements spécifié :
    
    result(0) sélectionne tous les enregistrements en mode
synchrone en renvoyant une table d'enregistrements.
    
    result(-1) sélectionne le prochain enregistrement disponible en
mode asynchrone.
    
    result(N) sélectionne l'enregistrement numéro
N en mode asynchrone.
    
    
    
    -- extrait un jeu d'enregistrements via une requête régulière :
local result, err = db:select(r, "SELECT * FROM `tbl` WHERE 1")

local rows = result(0) -- sélectionne tous les enregistrements en mode synchrone
local row = result(-1) -- sélectionne le prochain enregistrement disponible en mode asynchrone
local row = result(1234) -- sélectionne l'enregistrement 1234 en mode asynchrone
local row = result(-1, true) -- Lit l'enregistrement suivant en utilisant les noms d'enregistrements comme index.
    

    
    Il est possible de construire une fonction qui renvoie une
fonction itérative permettant de traiter tous les enregistrement en mode
synchrone ou asynchrone selon la valeur de l'argument async :
    
    
    
    function rows(resultset, async)
    local a = 0
    local function getnext()
        a = a + 1
        local row = resultset(-1)
        return row and a or nil, row
    end
    if not async then
        return pairs(resultset(0))
    else
        return getnext, self
    end
end

local statement, err = db:prepare(r, "SELECT * FROM `tbl` WHERE `age` > %u")
if not err then
     -- sélectionne des enregistrements en mode asynchrone :
    local result, err = statement:select(20)
    if not err then
        for index, row in rows(result, true) do
            ....
        end
    end

     -- sélectionne des enregistrements en mode synchrone :
    local result, err = statement:select(20)
    if not err then
        for index, row in rows(result, false) do
            ....
        end
    end
end
    

    
    
    Fermeture d'une connexion à une base de données
    
        

    
    Lorsqu'elles ne sont plus utilisées, les connexions aux bases de
données doivent être fermées avec database:close(). Si vous
ne les fermez pas manuellement, mod_lua les fermera peut-être en tant
que résidus collectés, mais si ce n'est pas le cas, vous pouvez finir
pas avoir trop de connexions vers la base de données inutilisées. Les
deux mesures suivantes sont pratiquement identiques :
    
    
    
    -- Méthode 1 : fermeture manuelle de la connexion
local database = r:dbacquire("mod_dbd")
database:close() -- c'est tout

-- Méthode 2 : on laisse le collecteur de résidus la fermer
local database = r:dbacquire("mod_dbd")
database = nil -- on coupe le lien
collectgarbage() -- fermeture de la connexion par le collecteur de résidus
    

    
    
    Précautions à prendre lorsque l'on travaille avec les bases
de données
    
    
    
    Bien que les fonctions query et run
soient toujours disponibles, il est recommandé d'utiliser des requêtes
préparées chaque fois que possible, afin d'une part d'optimiser les
performances (si votre connexion reste longtemps en vie), et d'autre part
minimiser le risque d'attaques par injection SQL. Les fonctions
run et query ne doivent être utilisées que
lorsque la requête ne contient pas de variables (requête statique). Dans
le cas des requêtes dynamiques, utilisez db:prepare ou
db:prepared.

    Cette directive permet de définir le comportement du cache de code
    en mémoire. La valeur par défaut est stat ; dans ce cas, le script
    du niveau le plus haut (et pas les scripts inclus) est vérifié à
    chaque fois que ce fichier est nécessaire, et est rechargé si la
    date de modification est plus récente que celle du script déjà
    chargé. Les autres valeurs permettent respectivement de garder le
    fichier en cache perpétuellement (forever - jamais vérifié ni
    remplacé), ou de ne jamais le mettre en cache (never).
    

    
    En général, les valeurs stat et forever sont utilisées pour un
    serveur en production, et les valeurs stat ou never pour un serveur
    en développement.

    Invoque une fonction lua au cours de la phase auth_checker du
traitement de la requête. Cette directive peut s'utiliser pour
implémenter une vérification arbitraire de l'authentification et de
l'autorisation. Voici un exemple très simple :

    

    require 'apache2'

-- fonction d'accroche authcheck fictive
-- Si la requête ne contient aucune donnée d'authentification, l'en-tête
-- de la réponse est défini et un code 401 est renvoyé afin de demander au
-- navigateur d'effectuer une authentification basique. Si la requête
-- comporte des données d'authentification, elles ne sont pas vraiment
-- consultées, mais on admet la prise en compte de l'utilisateur 'foo' et
-- on la valide. On vérifie ensuite si l'utilisateur est bien 'foo' et on
-- accepte la requête.
function authcheck_hook(r)

   -- recherche des informations d'authentification
   auth = r.headers_in['Authorization']
   if auth ~= nil then
     -- définition d'un utilisateur par défaut
     r.user = 'foo'
   end

   if r.user == nil then
      r:debug("authcheck: user is nil, returning 401")
      r.err_headers_out['WWW-Authenticate'] = 'Basic realm="WallyWorld"'
      return 401
   elseif r.user == "foo" then
      r:debug('user foo: OK')
   else
      r:debug("authcheck: user='" .. r.user .. "'")
      r.err_headers_out['WWW-Authenticate'] = 'Basic realm="WallyWorld"'
      return 401
   end
   return apache2.OK
end

    Ce dispositif d'insertion simple permet d'exécuter une fonction
    lorsque httpd entre dans la phase de journalisation du traitement
    d'une requête. Vous pouvez ainsi ajouter des données à vos propres
    entrées de journalisation, manipuler les entrées du journal standard
    avant leur enregistrement ou empêcher l'enregistrement d'une entrée
    dans le journal. Pour empêcher l'enregistrement normal des entrées
    du journal, renvoyez simplement apache2.DONE dans votre
    gestionnaire de journalisation, ou au contraire, renvoyez
    apache2.OK pour que httpd effectue une journalisation
    normale.

    

    Exemple :
    

    LuaHookLog "/path/to/script.lua" logger
    


    -- /path/to/script.lua --
function logger(r)
    -- on joue à pile ou face :
    -- Si on obtient 1, on écrit dans notre propre journal Lua et on dit
    -- à httpd de ne pas enregistrer d'entrée dans le journal standard..
    -- Si on obtient 2, on nettoie un peu les données avant que httpd ne
    -- les enregistre dans le journal standard.

    if math.random(1,2) == 1 then
        -- On effectue notre propre journalisation et le journal
	-- standard n'est pas alimenté
        local f = io.open("/foo/secret.log", "a")
        if f then
            f:write("Quelque chose de secret est arrivé à " .. r.uri .. "\n")
            f:close()
        end
        return apache2.DONE -- On dit à httpd de ne rien enregistrer
			    --dans le journal standard
    else
        r.uri = r.uri:gsub("somesecretstuff", "") -- nettoie les données
        return apache2.OK -- et httpd doit alors les enregistrer.

    Cette directive permet d'ajouter un point d'entrée (à
    APR_HOOK_MIDDLE) à la phase du nom de traduction du traitement de la
    requête. La fonction hook accepte un seul argument, le request_rec,
    et doit renvoyer un code d'état qui est soit un code d'erreur HTTP,
    ou une constante définie dans le module apache2 :  apache2.OK,
    apache2.DECLINED, ou apache2.DONE.
    

    
    Pour ceux qui ne sont pas familiers avec les points d'entrée
    (hook), en gros, chaque hook sera invoqué jusqu'à ce que l'un
    d'entre eux renvoie apache2.OK. Si un hook n'effectuer pas la
    traduction, il doit juste renvoyer apache2.DECLINED. Si le
    traitement de la requête doit être interrompu, la valeur renvoyée
    doit être apache2.DONE.
    

    
    Exemple :
    


    # httpd.conf
LuaHookTranslateName "/scripts/conf/hooks.lua" silly_mapper

    Par défaut, si des directives LuaHook* se trouvent dans
    des sections de configuration Directory ou Location qui se
    chevauchent, les scripts
    définis dans les sections les plus spécifiques s'exécutent
    après ceux définis dans les sections plus génériques
    (LuaInherit parent-first). Vous pouvez inverser cet ordre, ou faire
    en sorte que le contexte parent ne s'applique pas du tout.
    

    
    Jusqu'aux versions 2.3.x, le comportement par défaut consistait à
    ignorer les directives LuaHook* situées dans les sections de
    configuration parentes.

    Directive LuaInputFilter
    

    

    Description:Fournit une fonction Lua pour le filtrage en entrée
    

    Syntaxe:LuaInputFilter filter_name /path/to/lua/script.lua function_name
    

    Contexte:configuration globale

    Module:mod_lua
    

    Compatibilité:Disponible depuis la version 2.4.5 du serveur HTTP
Apache
    

    

    Cette directive permet d'ajouter un filtre en entrée sous la forme
d'une fonction Lua. A l'instar des filtres en sorties, les filtres en
entrée fonctionnent comme des sous-routines, intervenant dans un premier
temps avant l'envoi du contenu des tampons, puis chaque fois qu'un
paquet de données doit être transmis à la chaîne, et éventuellement
produisant toute donnée à ajouter aux données en entrée. La variable
globale bucket contient les paquets de données tels qu'ils
sont transmis au script Lua :

    


    LuaInputFilter myInputFilter "/www/filter.lua" input_filter
<Files "*.lua">
  SetInputFilter myInputFilter
</Files>
    


    --[[
    Exemple de filtre en entrée qui convertit toutes les données POST en
    majuscules.
]]--
function input_filter(r)
    print("luaInputFilter called") -- pour débogage
    coroutine.yield() -- attend des paquets de données
    while bucket do -- Pour chaque paquet, faire ...
        local output = string.upper(bucket) -- Convertit toutes les données POST en majuscules
        coroutine.yield(output) -- Envoie les données traitées à la chaîne de filtrage
    end
    -- plus aucune donnée à traiter.
    coroutine.yield("&filterSignature=1234") -- Ajoute une signature à la fin
end
    


    
Le filtre en entrée peut interdire ou sauter un filtre s'il est
considéré comme indésirable :

    

    function input_filter(r)
    if not good then
        return -- Empêche tout simplement le filtrage et transmet le contenu original
    end
    coroutine.yield() -- attend des paquets de données
    ...               -- insert les filtres ici
end

    Module:mod_lua
    

    
    
    Cette directive permet de faire correspondre un modèle d'uri avec
    une fonction de gestionnaire située dans un fichier spécifique. Elle
    utilise les expressions rationnelles PCRE pour mettre en
    correspondance l'uri, et supporte les groupes de correspondance
    d'interpolation dans le chemin du fichier et le nom de la fonction.
    Prenez garde aux problèmes de sécurité en écrivant vos expressions
    rationnelles.
    
   
    Exemples :
    LuaMapHandler "/(\w+)/(\w+)" "/scripts/$1.lua" "handle_$2"
    

    
        
    Cette directive va faire correspondre des uri comme
	/photos/show?id=9 au fichier /scripts/photos.lua, et invoquera la
	fonction de gestionnaire handle_show au niveau de la vm lua
	après chargement de ce fichier.
    


    LuaMapHandler "/bingo" "/scripts/wombat.lua"
    

        
    Cette directive invoquera la fonction "handle" qui est la
	valeur par défaut si aucun nom de fonction spécifique n'est
	spécifié.

    if not r.content_type:match("text/html") then
        return -- Empêche tout simplement le filtrage et transmet le contenu original

    ...               -- insert les filtres ici
end
    


    Les filtres Lua avec mod_filter
    

    Lorsqu'on utilise un filtre Lua comme fournisseur sous-jacent via la
directive FilterProvider, le
filtrage ne fonctionnera que si filter-name est identique à
provider-name.

    un serveur virtuel, et permet d'effectuer certains traitements avant
    le déroulement des autres phases, ou de servir une requête sans
    avoir à la traduire, l'associer à un espace de stockage, etc...
    Comme cette phase s'exécute avant toute autre, les directives telles
    que <Location> ou
    <Directory> ne
    sont pas encore prises en compte, car Les URI n'ont pas encore été
    entièrement interprétés.

    Module:mod_lua
    

    
    
    Cette directive permet de spécifier la durée de vie de
    l'interpréteur Lua qui sera utilisé dans ce "répertoire". La valeur
    par défaut est "once".
    

   
    
    
    once:
     
    utilise l'interpréteur une fois.
    

    
    request:
     
    utilise l'interpréteur pour traiter tout ce
    qui est basé sur le même fichier dans la requête, et qui se trouve
    aussi dans la portée de la requête.
    

    
    conn:
     
    idem request, mais attaché à connection_rec
    

    
    thread:
     
    Utilise l'interpréteur pendant toute la durée
    de vie du thread qui traite la requête (disponible seulement avec
    les MPMs threadés).
    

    
    server:
      
    Le comportement est ici différent, car la
    portée du serveur présente une durée de vie assez longue, et
    plusieurs threads vont partager le même server_rec. Pour gérer tout
    ceci, les états lua du serveur sont stockés dans une liste de ressources
    apr. Les arguments min et max permettent
    de spécifier les nombres minimaux et maximaux d'états lua à stocker
    dans la liste.
    
   
    
   
    En général, les portées thread et server
   sont 2 à 3 fois plus rapides que les autres, car elles n'ont pas besoin
   de régénérer de nouveaux états Lua à chaque requête (comme c'est le
   cas avec le MPM event, où même les connexions persistantes utilisent un
   nouveau thread pour chaque requête). Si vous pensez que vos scripts
   n'auront pas de problème s'il réutilisent un état, alors les portées
   thread ou server doivent être utilisées car
   elles présenteront de meilleures performances. Alors que la portée
   thread fournira les réponses les plus rapides, la portée
   server utilisera moins de mémoire car les états sont
   rassemblés dans des jeux, permettant par exemple à 1000 threads de
   partager 100 états Lua, ne nécessitant ainsi que 10% de la mémoire
   requise par la portée thread.

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:CGI スクリプトの実行
    

    ステータス:Base
    

    モジュール識別子:cgi_module
    

    ソースファイル:mod_cgi.c
    

    概要
    

    
    ハンドラ cgi-script
    が指定されているファイルは CGI スクリプトとして扱われ、
    サーバにより実行され、その出力がクライアントに返されます。
    ファイルは、AddHandler
    ディレクティブに指定された 拡張子を名前に含むか、
    ScriptAlias
    ディレクトリに存在することによりこのハンドラになります。
    

    
    Apache で CGI スクリプトを使用するためのイントロダクションは、
    CGI による動的コンテンツ
    を参照してください。
    

    
    Unix でマルチスレッドの MPM を使っている場合は、このモジュールの
    代わりに mod_cgid を使う必要があります。
    ユーザレベルではこの二つのモジュールは本質的には同一です。
    

    
    後方互換性のため、 MIME タイプが application/x-httpd-cgi 
    であるファイルでも cgi-script ハンドラが有効になります。この特殊な MIME タイプを
    使う方法は非推奨です。

    CGI 環境変数
    
    
    サーバは CGI
    規格 で決められている CGI
    環境変数を設定します。以下のものは、条件付きで設定されます。
    

    
    
      
    PATH_INFO
    

      
    これは AcceptPathInfo ディレクティブが明示的に off
      に設定されている場合は設定されません。デフォルトの、
      AcceptPathInfo が
      指定されていないときの振る舞いでは、mod_cgi はパス情報
      (URI のスクリプトのファイル名の後に続く /more/path/info) を
      受け付けますが、コアはサーバはパス情報のあるリクエストに
      対して 404 NOT FOUND エラーを返します。AcceptPathInfo
      ディレクティブを
      省略すると、mod_cgi へのリクエストに対して
      On を
      設定したのと同じ効果になります。
    

      
    REMOTE_HOST
    

      
    HostnameLookups
      が on (デフォルトでは off です)
      で、アクセスしているホストのアドレスの DNS
      の逆引きが実際にホスト名を見つけたときにのみ設定されます。
    

      
    REMOTE_IDENT
    

      
    IdentityCheck
      が on に設定されていて、アクセスしているホストが
      ident プロトコルをサポートしているときにのみ設定されます。
      これは簡単に偽ることができ、クライアントとサーバの間に
      プロキシがあればまったく役に立たないので、
      この変数の値は信用できないということに注意してください。
      
    

      
    REMOTE_USER
    

      
    CGI
      スクリプトに認証が必要なときにのみ設定されます。
    
    
    

    top
    

    

    CGI のデバッグ
    
    
    CGI スクリプトのデバッグは、正しく動作していないスクリプトの出力
    (標準出力とエラー)
    を調べることができないために、難しい状態が続いていました。
    これらのディレクティブはより詳細なエラーのログ収集を提供します。
    

    
    CGI ログファイルの書式
    
	
    設定されているときには、CGI エラーログは適切に動作しないすべての
	CGI をログ収集します。それぞれの正しく動作しない CGI
	スクリプトは 複数の行にわたる情報がログ収集されます。最初の
	2 行は常に以下の書式です:
    

      
    
        %% [time] request-line
    
        %% HTTP-status CGI-script-filename
      
    

      
    エラーが、CGI スクリプトが実行できないというものである場合は、
      ログファイルはさらにもう 2 行書かれます:
    

      
    
        %%error
    
        error-message
      
    

      
    そうではなく、エラーが正しくないヘッダ情報を返す結果である場合
      (スクリプトのバグであることがよくあります)、
      以下の情報がログ収集されます:
    

    
    
      %request
    
      受け取ったすべての HTTP リクエストヘッダ
    
      (もしあれば) POST や PUT の中身
    
      %response
    
      CGI スクリプトにより出力されたすべてのヘッダ
    
      %stdout
    
      CGI 標準出力
    
      %stderr
    
      CGI 標準エラー
    
    
    

    
    (スクリプトが標準出力や標準エラーに何も出力しなかった場合は、
    %stdout や %stderr はありません)。
    


    

    top
    

    ScriptLog ディレクティブ
    

    

    説明:CGI スクリプトのエラーログファイルの場所
    

    構文:ScriptLog file-path
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_cgi, mod_cgid
    

    
    
    ScriptLog ディレクティブは CGI スクリプトの
    エラーログファイルを設定します。ScriptLog が
    設定されていないときは、
    エラーログは作成されません。設定されているときは、CGI
    のエラーはすべて引数として与えられているファイル名にログされます。
    相対パスで指定されているときは、
    ServerRootからの相対パスとして
    扱われます。
    

    
    例
    ScriptLog logs/cgi_log
    

    

    
    このログは子プロセスが実行されているユーザとしてオープンされます。
    すなわち、User ディレクティブで指定された
    ユーザです。これは、スクリプトログが書かれるディレクトリがそのユーザで
    書き込み可能か、スクリプトファイルが手動で作成され、そのユーザで
    書き込み可能になっている必要があるということです。スクリプトログを
    アクセスログなどのためのログディレクトリに書かれるようにしたときは、
    そのディレクトリを子プロセスを実行しているユーザの権限で
    書き込み可能にはしないようにしてください。
    

    
    スクリプトのログ収集は CGI スクリプトを書くときの
    デバッグ用の機能として意図されていて、通常のサーバで
    常に使用されるようには意図されていないということに注意してください。
    速度や効率は最適化されておらず、設計された以外の方法で使用されると
    セキュリティの問題があるかもしれません。
    


    

    top
    

    ScriptLogBuffer ディレクティブ
    

    

    説明:スクリプトログに記録される PUT や POST リクエストの内容の上限
    

    構文:ScriptLogBuffer bytes
    

    デフォルト:ScriptLogBuffer 1024
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_cgi, mod_cgid
    

    
    
    大きな本体を受け取ったときにログファイルがすぐに大きくなりすぎる
    問題を避けるために、ファイルにログ収集される PUT と POST
    の本体の大きさは制限されています。デフォルトでは、1024
    バイトまでがログ収集されますが、
    このディレクティブはそれを変更することができます。 
    
    


    

    top
    

    ScriptLogLength ディレクティブ
    

    

    説明:CGI スクリプトのログファイルの大きさの上限
    

    構文:ScriptLogLength bytes
    

    デフォルト:ScriptLogLength 10385760
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Base
    

    モジュール:mod_cgi, mod_cgid
    

    
    
    ScriptLogLength は CGI スクリプトのログファイル
    の大きさを制限するために使用することができます。ログファイルは
    CGI のエラー毎に大量の情報 (リクエストのすべてのヘッダ、
    すべての出力)をログしますので、すぐに大きなファイルになります。
    この大きさの制限がないことによる問題を防ぐために、
    このディレクティブを使って CGI のログファイルの
    最大のファイルサイズを設定することができます。
    ファイルがこの大きさを超えた場合は、それ以上は書き込まれません。

    AcceptFilter ディレクティブ
    

    

    説明:プロトコルを Listen しているソケットの最適化を設定する
    

    構文:AcceptFilter protocol accept_filter
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:Core
    

    モジュール:core
    

    互換性:2.1.5 以降
    

    
    
    Listen しているソケットに対して、OS が固有に持っているプロトコルについての最適化を
       有効にするディレクティブです。大前提となる条件は、データが受信されるか
       HTTP リクエスト全体がバッファされるかするまで、カーネルがサーバプロセスに
       ソケットを送らないようになっている、ということです。現在サポートされているのは、
       
       FreeBSD の Accept Filter と Linux のプリミティブな
       TCP_DEFER_ACCEPT のみです。
    

    
    FreeBSD のデフォルト値は :
    
    
    
        AcceptFilter http httpready 
    
        AcceptFilter https dataready
    
    
    
    
    httpready Accept Filter は HTTP リクエスト全体を、
       カーネルレベルでバッファリングします。リクエスト全体を受信し終わると、
       その後サーバプロセスにそれを送ります。詳細については accf_http(9) 
       を参照してください。HTTPS のリクエストは暗号化されているので accf_data(9)
       フィルタのみが使用されます。
    

    
    Linux でのデフォルト値は :
    
    
    
        AcceptFilter http data 
    
        AcceptFilter https data
    
    

    
    Linux の TCP_DEFER_ACCEPT は HTTP リクエストのバッファリングを
       サポートしていません。none 以外の値で
       TCP_DEFER_ACCEPT が有効になります。詳細については Linux 
       man ページ tcp(7)
       を参照してください。
    

    
    引数に none を指定すると、プロトコルに対する全ての Accept 
       Filter が無効になります。nntp といった、先にサーバにデータを
       送る必要のあるプロトコルに有効です :
    
    
    AcceptFilter nntp none

    AcceptPathInfo ディレクティブ
    

    

    説明:後に続くパス名情報を受け付けるリソースの指定
    

    構文:AcceptPathInfo On|Off|Default
    

    デフォルト:AcceptPathInfo Default
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:Core
    

    モジュール:core
    

    互換性:Apache 2.0.30 以降で使用可能
    

    

    
    このディレクティブは実際のファイル名 (もしくは存在するディレクトリの
    存在しないファイル) の後に続くパス名情報があるリクエストを受け付けるか
    拒否するかを制御します。続きのパス名情報はスクリプトには PATH_INFO
    環境変数として利用可能になります。
    

    
    例えば、/test/ が、here.html というファイル
    一つのみがあるディレクトリを指しているとします。そうすると、
    /test/here.html/more と /test/nothere.html/more
    へのリクエストは両方とも /more を PATH_INFO とします。
    

    
    AcceptPathInfo ディレクティブに指定可能な
    三つの引数は:
    

    
    
    
    Off
    リクエストは存在するパスにそのまま
    マップされる場合にのみ受け付けられます。ですから、上の例の
    /test/here.html/more のように、本当のファイル名の
    後にパス名情報が続くリクエストには 404 NOT FOUND エラーが返ります。
    

    
    On
    前の方のパスが存在するファイルにマップする場合は
    リクエストが受け付けられます。上の例の /test/here.html/more
    は /test/here.html が有効なファイルにマップすれば
    受け付けられます。
    
    
    
    Default
    続きのパス名情報の扱いはリクエストの
    ハンドラで決まります。
    普通のファイルのためのコアハンドラのデフォルトは PATH_INFO を拒否します。
    cgi-script や isapi-handler のようにスクリプトを扱うハンドラは
    一般的にデフォルトで PATH_INFO を受け付けます。
    
    
    

    
    AcceptPathInfo の主な目的はハンドラの PATH_INFO を
    受け付けるか拒否するかの選択を上書きできるようにすることです。
    例えば、これは例えば INCLUDES のような
    フィルタを使って PATH_INFO に
    基づいてコンテンツを生成しているときに必要になります。
    コアハンドラでは通常拒否されるので、そういったスクリプトを動作させるには
    次のような設定を使います。
    

    
    
      <Files "mypaths.shtml">
    
      
        Options +Includes
    
        SetOutputFilter INCLUDES
    
        AcceptPathInfo On
    
          
      </Files>

    AccessFileName ディレクティブ
    

    

    説明:分散設定ファイルの名前
    

    構文:AccessFileName filename [filename] ...
    

    デフォルト:AccessFileName .htaccess
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Core
    

    モジュール:core
    

    
    
    リクエストを処理するとき、サーバはディレクトリに
    対して分散設定ファイルが有効になっていれば、
    そのドキュメントへの
    パス上にある全てのディレクトリから、ここで指定された名前の一覧の中で
    最初に見つかったファイルをそれぞれ設定ファイルとして読み込みます。例えば:
    

    
    
      AccessFileName .acl
    
    

    
    という設定があると、以下のようにして無効にされていない限り、
    ドキュメント /usr/local/web/index.html
    を返す前に、サーバは /.acl, /usr/.acl,
    /usr/local/.acl, /usr/local/web/.acl から
    ディレクティブを読み込みます。
    

    
    
      <Directory />
    
      
        AllowOverride None
    
          
      </Directory>

    AddDefaultCharset ディレクティブ
    

    

    説明:レスポンスのコンテントタイプが text/plain あるいは
text/html の場合に追加するデフォルトの charset パラメータ
    

    構文:AddDefaultCharset On|Off|charset
    

    デフォルト:AddDefaultCharset Off
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:Core
    

    モジュール:core
    

    
    
    レスポンスのコンテントタイプが text/plain 
    あるいは text/html 
    の場合に限りますが、レスポンスに追加するメディアタイプの文字セットパラメータ
    (文字エンコーディングの名前) のデフォルト値を、このディレクティブで指定します。
    これはレスポンス (訳注: レスポンスの HTML) 内で META 
    要素で指定された、どのような文字セットも無効にしますが、
    最終的な挙動はユーザのクライアント側の設定で決まります。
    この機能は AddDefaultCharset Off という設定で無効になります。
    AddDefaultCharset On にすれば、
    Apache 内部のデフォルト文字セット iso-8859-1 に設定されます。
    その他 charset に指定できる値であれば、どんな値でも使えます。
    指定する値は、MIME メディアタイプとして使われる
    IANA 
    に登録されている文字セット名のうちの一つにすべきです。
    例えば:
    

    
    
      AddDefaultCharset utf-8
    
    

    
    AddDefaultCharset を使うときは、全てのテキストリソースが
    指定する文字エンコードになっていると分かっていて、かつ、
    リソースの個々に文字セットを指定するのが大変な場合のみです。
    例を挙げると、レガシーな CGI スクリプトなどの、動的に生成される
    コンテンツを含むリソースに文字セットパラメータを追加する場合で、
    ユーザの入力データが出力に入り、クロスサイトスクリプティングが
    引き起こされうる場合です。デフォルト文字セットをセットしたとしても、
    ブラウザの "文字エンコードの自動選択" 機能が有効になっているユーザを
    守ることにはならないので、もちろんより良い解決策は単にスクリプトを修正
    (あるいは削除) することです。

    AllowEncodedSlashes ディレクティブ
    

    

    説明:URL 中の符号化されたパス分離文字が先に伝えられるのを許可するかどうかを
決定する
    

    構文:AllowEncodedSlashes On|Off
    

    デフォルト:AllowEncodedSlashes Off
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Core
    

    モジュール:core
    

    互換性:Apache 2.0.46 以降で使用可能
    

    
    
    AllowEncodedSlashes ディレクティブは符号化された
    パス分離文字 (/ は %2F、さらにシステムによっては
    \ に対応する %5C) が存在する URL の使用を
    許可するかどうかを決定します。通常はそのような URL は 404 (Not found) エラー
    で拒否されます。
    

    
    AllowEncodedSlashes On による
    パス分離文字の使用は、PATH_INFO と合わせて
    使うときに一番役に立ちます。
    

    
    注
    
      
    符号化されたスラッシュを許可することは、復号をすることを
       意味しません。%2F や (関係するシステムでの)
       %5C は、他の部分が復号された URL の中でもそのままの形式で
       残されます。

    AllowOverride ディレクティブ
    

    

    説明:.htaccess で許可されるディレクティブの種類
    

    構文:AllowOverride All|None|directive-type 
[directive-type] ...
    

    デフォルト:AllowOverride All
    

    コンテキスト:ディレクトリ
    

    ステータス:Core
    

    モジュール:core
    

    
    
    サーバが (AccessFileName によって指定された)
    .htaccess ファイルを見つけた時、そのファイルの中で
    宣言されたどのディレクティブがより前に定義された設定ディレクティブを
    上書きできるかを知る必要があります。
    

    
    <Directory> セクションでのみ使用可能
    
    AllowOverride は正規表現無しの<Directory>
    セクションでのみ有効で、<Location> や <DirectoryMatch>
    や <Files> セクションでは無効です。
    
    

    
    このディレクティブを None に設定すると、.htaccess ファイルは完全に
    無視されます。
    この場合、サーバはファイルシステムの .htaccess ファイルを読むことを
    試みさえしません。
    

    
    このディレクティブが All に設定されている時には、
    .htaccess という コンテキスト を持つ
    全てのディレクティブが利用できます。
    

    
    directive-type には、以下のディレクティブ群の
    キーワードのどれかを指定します。
    

    
    
      
    AuthConfig
    

      
    

      認証に関するディレクティブの使用を許可する (AuthDBMGroupFile,
      AuthDBMUserFile,
      AuthGroupFile,
      AuthName, 
      AuthType, AuthUserFile, Require など)。
    

      
    FileInfo
    

      
    
      ドキュメントタイプを制御するためのディレクティブの使用を許可する (DefaultType, ErrorDocument, ForceType, LanguagePriority,
      SetHandler, SetInputFilter, SetOutputFilter, 
      mod_mime の Add* と Remove*
      ディレクティブなど),
      ドキュメントのメタデータ (Header, RequestHeader, SetEnvIf, SetEnvIfNoCase, BrowserMatch, CookieExpires, CookieDomain, CookieStyle, CookieTracking, CookieName),
      mod_rewrite のディレクティブ RewriteEngine, RewriteOptions, RewriteBase, RewriteCond, RewriteRule) と
      mod_actions の
      Action
      ディレクティブ。
      
    

      
    Indexes
    

      
    
      ディレクトリインデックスを制御するためのディレクティブの使用を許可する
      (AddDescription,
      AddIcon, AddIconByEncoding,
      AddIconByType,
      DefaultIcon, DirectoryIndex, FancyIndexing, HeaderName, IndexIgnore, IndexOptions, ReadmeName
      など)。
    

      
    Limit
    

      
    
      ホストへのアクセス制御を行うためのディレクティブの使用を許可する (Allow, Deny, Order).
    

      
    Options[=Option,...]
    

      
    
      特定のディレクトリにおける機能を指定するためのディレクティブの使用を許可する
      (Options と
      XBitHack)。
      Options で設定するオプション
      を、(空白を含めない) コンマ区切りのリストにして等号の後に続けることで
      設定できます。
    
    
    

    
    例:
    

    
    
      AllowOverride AuthConfig Indexes
    
    

    
    上の例では AuthConfig と Indexes のどちらにも
    属さないディレクティブはすべて内部サーバエラーを引き起こします。

    このディレクティブは Apache が CGI スクリプトを実行するための
    インタープリタを探す方法を制御します。
    例えば、CGIMapExtension sys:\foo.nlm .foo と設定すると
    .foo という拡張子のすべての CGI スクリプトは FOO インタープリタに
    渡されます。

    このディレクティブは、RFC1864 及び RFC2616 において定義されている
    Content-MD5 ヘッダーの生成を有効にします。
    

    
    MD5 は、任意長のデータの「メッセージダイジェスト」(「指紋」
    と表現されることもある) を計算するアルゴリズムで、
    データの変更があった場合には非常に高い信頼度でメッセージダイジェストに変更が
    反映されます。
    

    
    Content-MD5 ヘッダは、エンドツーエンドで
    エンティティボディーに含まれるメッセージの完全性チェック
    (Message Integrity Check - MIC)を提供します。
    このヘッダを調べることで、プロキシやクライアントは、
    途中経路におけるエンティティボディの予期せぬ変更などを
    検出することができます。ヘッダの例:
    

    
    
      Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
    
    

    
    リクエスト毎にメッセージダイジェストを計算する (値はキャッシュされません)
    ことから、
    サーバパフォーマンスが低下することについて注意してください。
    

    
    Content-MD5は、core 機能により処理された
    ドキュメントを送るときのみ有効であり、
    SSI ドキュメントや CGI スクリプトの出力、バイトレンジを指定した
    応答の場合にはこのヘッダは付与されません。

    ステータス:Core
    

    モジュール:core
    

    互換性:引数 none は Apache 2.2.7 以降で利用可能
    

    
    
    サーバは、MIME タイプ
    のマップからは決定できないドキュメントの送信を要求されることがあります。
    

    
    サーバは、ドキュメントのコンテントタイプをクライアントに通知するべきです。
    サーバで通常の方法ではこれが判定できない場合は、
    DefaultType で指定されたタイプを利用します。
    例:
    

    
    
      DefaultType image/gif
    
    

    
    これは .gif という拡張子がファイル名に含まれていない
    多くの GIF 画像が含まれているディレクトリに適しているでしょう。
    

    
    サーバでも管理者でも判定することができない (例えばプロクシの) 場合、
    誤った情報を与えるよりは MIME タイプの指定がない状態が望ましいことも
    あります。この場合は次のようにします :
    
    
    
      DefaultType None
    
    
    
    DefaultType None は httpd-2.2.7 
    以降でのみ利用できます。
    

    
    ForceType ディレクティブと
    違って、このディレクティブはデフォルトの MIME タイプを提供するだけで
    あることに注意してください。ファイル名の拡張子を含め、
    メディアタイプを決定できる他の MIME タイプの定義があれば
    このデフォルトは上書きされます。

    シェルにおける指定同様、文字の範囲を [] で指定できます。
    ワイルドカードは `/' 文字にはマッチしませんので、
    /home/user/public_html には
    <Directory /*/public_html> はマッチしませんが、
    <Directory /home/*/public_html> はマッチします。
    例:
    

    
    
      <Directory /usr/local/httpd/htdocs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
    

    
    
      
    directory-path 引数には注意してください: その引数は
      Apache がファイルをアクセスするために使うファイルシステムのパスに
      そのままマッチする必要があります。ある <Directory> に
      適用されるディレクティブは、別のシンボリックリンクをたどったりして
      同じディレクトリを違うパスでアクセスした場合には適用されません。
    
    
    

    
    ~ という文字を
    付加することで正規表現を利用することもできます。
    例えば:
    

    
    
      <Directory ~ "^/www/.*/[0-9]{3}">
    
    

    
    といった指定の場合、/www/ 以下にある数字
    3 文字のディレクトリにマッチします。
    

    
    もし複数の (正規表現以外の) <Directory>セクションが
    ドキュメントを含むディレクトリ (やその上位ディレクトリのどれか) とマッチしたならば、
    .htaccess ファイルのディレクティブも読み込みつつ、
    短いパスから順に適用されます。
    例えば、
    

    
    
      <Directory />
    
      
        AllowOverride None
    
          
      </Directory>
    
      
    
      <Directory /home/>
    
      
        AllowOverride FileInfo
    
          
      </Directory>
    
    

    
    と設定し、ドキュメント /home/web/dir/doc.html への
    アクセスがあった場合には以下のように動作します:
    

    
      
      
    • AllowOverride None が適用される。
      (.htaccess ファイルは無効になる)
      • 

      
    • AllowOverride FileInfo が適用される
      (/home ディレクトリに対して)。
      • 

      
    • /home/.htaccess, /home/web/.htaccess,
      /home/web/dir/.htaccess の順にそれらのファイル中の
       FileInfo ディレクティブが適用される。
      • 
    
    

    
    正規表現は、通常のセクションがすべて適用されるまで
    考慮されません。
    その後、全ての正規表現が設定ファイルに現れた順で試されます。
    例えば、以下のような場合に
    

    
    
      <Directory ~ abc$>
    
      
        # ... directives here ...
    
          
      </Directory>
    
    

    
    正規表現のセクションはすべての通常の <Directory> と
    .htaccess の適用が終わるまで考慮されません。
    その後で、正規表現は /home/abc/public_html/abc にマッチし、
    対応する <Directory> が適用されます。
    

    
    Apache のデフォルトでは <Directory /> へのアクセスは
    Allow from All になっていることに注意してください。
    これは、URL からマップされたどのファイルでも Apache は送るということです。
    これは以下のようにして変更することが推奨されています。
    

    
    
      <Directory />
    
      
        Order Deny,Allow
    
        Deny from All
    
          
      </Directory>
    
    

    
    そしてアクセスを可能にしたいディレクトリに対して
    個別に設定すればよいでしょう。
    このあたりについては、セキュリティに関するコツを
    参照してください。
    

    
    ディレクトリセクションは httpd.conf ファイルに書きます。
    <Directory>
    ディレクティブは入れ子にすることができず、
    <Limit> や <LimitExcept> セクションの中にも
    記述できません。

    このディレクティブは配送中にファイルの内容を読み込む必要があるときに
    httpd がメモリマッピングを使うかどうかを制御します。
    デフォルトでは、
    例えば、mod_include を使って SSI ファイルを配送
    するときのように、ファイルの途中のデータをアクセスする必要があるときには
    Apache は OS がサポートしていればファイルをメモリにマップします。
    

    
    
    このメモリマップは性能の向上をもたらすことがあります。
    しかし、環境によっては運用上の問題を防ぐためにメモリマッピングを
    使用しないようにした方が良い場合もあります:
    

    
      
    
    • マルチプロセッサシステムの中にはメモリマッピングをすると
    httpd の性能が落ちるものがあります。
      • 
    
    • NFS マウントされた DocumentRoot
    では、httpd がメモリマップしている間にファイルが削除されたり
    短くなったりしたときに起こるセグメンテーションフォールトのために
    httpd がクラッシュする可能性があります。
      • 
    
    

    
    これらの問題に当てはまるサーバの設定の場合は、以下のようにして
    ファイルの配送時のメモリマッピングを使用不可にしてください:
    

    
    
      EnableMMAP Off
    
    

    
    NFS マウントされたファイルには、問題のあるファイルにのみ明示的に
    この機能を使用不可にします:
    

    
    
      <Directory "/path-to-nfs-files">

    このディレクティブはクライアントにファイルの内容を送るときに
    httpd がカーネルの
    sendfile サポートを使うかどうかを制御します。デフォルトでは、
    例えば静的なファイルの配送のように、リクエストの処理にファイルの
    途中のデータのアクセスを必要としないときには、Apache は OS が
    サポートしていればファイルを読み込むことなく sendfile を使って
    ファイルの内容を送ります。
    

    
    sendfile は read と send を別々に行なうことと、バッファの割り当てを
    回避します。しかし、プラットフォームやファイルシステムの中には
    運用上の問題を避けるためにこの機能を使用不可にした方が良い場合があります:
    

    
      
    
    • プラットフォームの中にはビルドシステムが検知できなかった、壊れた
    sendfile のサポートが存在するものがあります。これは特に
    バイナリが別のマシンでビルドされ、壊れた sendfile のあるマシンに
    移動したときに起こります。
      • 
    
    • Linux では、sendfile を用いると、
    IPv6 使用時に存在する特定ネットワークカードの TCP-checksum
    オフロードのバグを踏んでしまいます。
      • 
    
    • Itanium 上の Linux では、sendfile では 2GB 以上の
    ファイルを扱うことができません。
      • 
    
    • ネットワークマウントされた DocumentRoot
    (例えば NFS や SMB)
    では、カーネルは自身のキャッシュを使ってネットワークからのファイルを
    送ることができないことがあります。
      • 
    
    

    
    これらの問題に当てはまるサーバの設定の場合は、以下のようにして
    この機能を使用不可にしてください:

    問題やエラーが発生したときの動作として、
    Apache には以下の四つのうち一つの動作を設定することができます。
    

    
      
      
    1. Apache 標準の簡単なエラーメッセージを表示
      2. 

      
    2. 自分で指定したメッセージを表示
      3. 

      
    3. 問題やエラーの処理をする為に、自サーバ内の
      URL-path へリダイレクト
      4. 

      
    4. 問題やエラーの処理をする為に、外部の URL へリダイレクト
      5. 
    
    

    
    最初のものがデフォルトの動作で、2 番目から 4 番目は、
    ErrorDocumentディレクティブにより、
    HTTP のレスポンスコードと、メッセージか URL を指定することで設定します。
    Apache が問題もしくはエラーに関する追加情報を提供することがあります。
    

    
    URL の場合は、スラッシュで始まる (/) ローカルの web-path (
    DocumentRoot からの相対パス
    ) か、クライアントが解決できる完全な URL を指定します。
    もしくは、ブラウザに表示されるメッセージを指定できます。
    例:
    

    
    
      ErrorDocument 500 http://foo.example.com/cgi-bin/tester
    
      ErrorDocument 404 /cgi-bin/bad_urls.pl
    
      ErrorDocument 401 /subscription_info.html
    
      ErrorDocument 403 "Sorry can't allow you access today"
    
    

    
    加えて、特別な値 default を使って Apache に
    ハードコードされている簡単なメッセージを指定することができます。
    通常は必要ではありませんが、default を使うと
    既存の ErrorDocument ディレクティブの設定を
    継承するところで、Apache のハードコードされた簡単なメッセージに
    戻すことができます。
    

    
    
      ErrorDocument 404 /cgi-bin/bad_urls.pl

    
      <Directory /web/docs>
    
      
        ErrorDocument 404 default
    
          
      </Directory>
    
    

    
    リモート URL (例えば、頭に http と付与した方法) を
    ErrorDocument に指定するとき、
    たとえ文書が同じサーバにあろうとも、ドキュメントがどこにあるかを通知するために、
    Apache はリダイレクトをクライアントに送出するということに、注意してください。
    これにはいろいろと関連して起こる問題があります。
    中でも最も重要なのは、クライアントは元々のエラーステータスコードを受け取らず、
    代わりにリダイレクトのステータスコードを受け取るということです。
    これにより、ステータスコードを使って URL が有効であるかどうかを決定しようとする
    ウェブロボットやその他クライアントを、混乱させるかもしれません。
    さらに、ErrorDocument 401 にリモートの URL を指定すると、
    クライアントは 401 というステータスコードを受け取らないため、
    パスワードをユーザーに入力要求しなければならないことがわかりません。
    従って、ErrorDocument 401 というディレクティブを使う場合は、
    必ずローカルな文書を参照しなければなりません。
    

    
    Microsoft Internet Explorer (MSIE) はデフォルトではサーバが生成したエラーメッセージが
    「小さすぎる」ときには無視をして自分自身の「やさしい」エラーメッセージで
    置換します。サイズのしきい値はエラーの種類によって異なりますが、
    一般的にはエラーの文書を 512 バイトよりも大きくすると、MSIE は
    サーバが生成したエラーを隠さずに表示します。詳しい情報は Microsoft
    Knowledge Base の記事 Q294807
    にあります。
    

    
    ほとんどのエラーメッセージを上書きすることができますが、特定の状況下では
    ErrorDocument の設定にかかわらず
    内蔵のメッセージが使われます。
    特に、不正な形式のリクエストが検出された場合、通常のリクエスト処理は
    即座に中止され、内蔵のエラーメッセージが返されます。
    この処置は不正なリクエストによって引き起こされる、セキュリティ問題から
    守るために必要な措置です。
    

    
    2.0 より前のバージョンでは、対になっていない二重引用符を
    先頭に付けることによりメッセージであることを指定していました。

    ErrorLog ディレクティブは、
    サーバに生じたさまざまなエラーを
    記録する為のファイルの名前を設定します。
    file-path が絶対パスでないときは、ServerRoot からの相対パスとみなされます。
    

    
    例
    
    ErrorLog /var/log/httpd/error_log
    
    
    
    
    file-path がパイプ (|) から始まる場合は、
    エラーログを処理するために実行されるコマンドが
    指定されていると解釈されます。
    

    
    例
    
    ErrorLog "|/usr/local/bin/httpd_errors"
    
    

    
    ファイル名の変わりに syslog と指定することによって、
    システムがサポートしていれば syslogd(8) を利用したロギングが有効になります。
    デフォルトでは、local7 ファシリティとなりますが、
    syslog:facility といった形で記述することにより、
    通常 syslog(1) のドキュメントで説明されているファシリティの一つを使うように
    することができます。
    

    
    例
    
    ErrorLog syslog:user

    Unix 以外のプラットフォームでファイルのパスを入力するときは、

      確実にスラッシュのみが使用されるように注意してください。一般的には、
      設定ファイル全般でスラッシュのみを使う方が良いでしょう。

    WebDAV を使っていて、mod_dav_fs をストレージプロバイダとして
    使っているような Directory や Location では、デフォルト値を変更しないでください。

    の固定フォーマットを使っています。
    FileETag で ETag フォーマットを
    変更してしまうと、条件付リクエストでうまく動作しなくなります。

    <Files> ディレクティブは、
    その中にあるディレクティブの適用範囲をファイル名で制限します。
    <Directory> ディレクティブや <Location> ディレクティブと
    同じような機能を持ちます。
    これは、</Files> ディレクティブと対に
    なっていなければなりません。
    このセクション中のディレクティブは、ベース名 (ファイル名の最後の部分)
    が指定されたファイル名にマッチするすべてのオブジェクトに適用されます。
    <Files> セクションは
    <Directory> セクションと
    .htaccess が読み込まれた後、
    <Location> セクションよりは先に
    設定ファイルに現れた順に適用されます。
    <Files> は、
    <Directory> セクション内に
    ネストさせることができ、
    ファイルシステムの一部にのみ限定して適用させることができます。
    

    
    filename 引数は、ファイル名かワイルドカード文字列
    で、ワイルドカードでは ? は一つの文字、* は任意の文字列にマッチします。
    ~ という文字を付加することで正規表現を使うこともできます。
    例えば、
    

    
    
      <Files ~ "\.(gif|jpe?g|png)$">
    
    

    
    とすることにより、一般的なインターネットの画像フォーマットにマッチします。
    ただし、
    <FilesMatch> を使う方が
    推奨されています。
    

    
    ちなみに、<Directory> と <Location> セクションとは異なり、
    <Files>
    は .htaccess ファイル内で利用することができます。
    これにより、ユーザがファイル毎にアクセスの制御を行なうことができるように
    なっています。

    このディレクティブは、ホスト名をログ収集できるように
    DNS ルックアップを有効にします
    (さらに、CGI/SSI に REMOTE_HOST 変数として渡します)。
    Doubleを指定した場合、2 重の逆引きを行ないます。
    つまり、逆引きの後に、その結果に対して正引きを行ないます。正引きの
    結果の IP アドレスの中にオリジナルのアドレスと一致するものがなければ
    なりません。("tcpwrappers" の用語では PARANOID と呼ばれています。)
    

    
    mod_authz_host でホスト名によるアクセス
    制御を行なう場合には、
    設定の如何によらず 2 重の逆引きが実行されます。
    これは、セキュリティを保つために必要です。
    HostnameLookups Double を設定しない限り、
    他の部分はこの 2 重逆引きの結果を使うことはできません。
    例えば、HostnameLookups On と設定してある状態で、
    ホスト名によるアクセス制限を行なったオブジェクトへの
    リクエストを受けたとすると、2 重の逆引きが成功するか否かによらず、
    REMOTE_HOST には通常の逆引き結果が渡されます。
    

    
    ディレクティブのデフォルトは
    本当に逆引きを必要としているわけではないサイトの
    ネットワークトラフィックを低減させるために、Off になっています。
    ルックアップによる余計な遅延がなくなるため、
    エンドユーザにとっても良いでしょう。
    DNS のルックアップには、かなりの時間が必要となる場合が多く、
    負荷の高いサイトではこのディレクティブは Off にすべきです。
    なお、/support ディレクトリに含まれ、デフォルトでは
    インストールディレクトリの bin サブディレクトリに
    インストールされる logresolve ユーティリティにより、
    Apache の動作とは別に、ログに残されている IP アドレスからホスト名を
    ルックアップすることが可能です。

    KeepAlive On と設定します。
    

    
    HTTP/1.0 に対応したクライアントの際には、
    クライアントより特に要求があった場合のみ Keep-Alive 接続となります。
    さらに、HTTP/1.0 クライアントでは、コンテンツの容量が先に
    (訳注: 要求に対して応答を返す前に) わかる場合のみ Keep-Alive
    接続を利用できます。
    これは、CGI の出力や SSI のページ、
    サーバが生成したディレクトリのリストのような動的コンテンツを
    HTTP/1.0 クライアントに送る場合には Keep-Alive 接続を使えないことを意味します。
    HTTP/1.1 に対応したクライアントの際には、
    特に指定されない限りはデフォルトとして持続的な接続が行なわれます。
    クライアントが要求すれば、コンテンツの容量を判別できないものを
    持続的な接続を通して送るために、チャンクエンコーディングが用いられます。
    

    
    クライアントが Keep-Alive コネクションを使用している場合、
    そのコネクションを通してどれだけたくさんのリクエストが処理されても、

    アクセス制御は、通常全てのアクセスメソッドに対して
    影響し、普通はこれが望ましい挙動です。
    そうしたことから、大部分の場合にはアクセス制御に関わるディレクティブを
    <Limit> セクション内に
    書くべきではありません。 
    

    
    <Limit> ディレクティブの
    目的は、アクセス制御の範囲を
    指定された HTTP メソッドに限定するためです。
    それ以外のメソッドは、<Limit> で囲われたアクセス制御の
    影響を受けません。
    以下の例は、POST, PUT, DELETE のメソッドに対してのみアクセスの制御を行ない、
    それ以外のメソッドについては制限しません:
    

    
    
      <Limit POST PUT DELETE>
    
      
        Require valid-user
    
          
      </Limit>
    
    

    
    メソッド名には以下の中から一つ以上を列挙することができます:
    GET,
    POST, PUT, DELETE,
    CONNECT, OPTIONS,
    PATCH, PROPFIND, PROPPATCH,
    MKCOL, COPY, MOVE,
    LOCK, UNLOCK. メソッド名は
    大文字小文字を区別します。 GET を指定した場合には
    HEAD リクエストにも制限がかかります。TRACE
    メソッドに制限をかけることはできません
    (<TraceEnable> 参照)。
    

    
    アクセス制御が目的の場合は
    <Limit> 
    セクションの代わりに <LimitExcept> セクションを使用した方が良いでしょう。
    <LimitExcept>
    セクションでは不特定のメソッドに対しても防御できるからです。

    内部リダイレクトは例えば Action ディレクティブを
    使っているときに起こります。Action ディレクティブは
    元々のリクエストを CGI スクリプトに内部リダイレクトを行ないます。
    サブリクエストはいくつかの URI に対して、リクエストされたときに
    何が起こるかを調べるための Apache の機構です。例えば、mod_dir
    は DirectoryIndex ディレクティブ
    がリストするファイルを調べるためにサブリクエストを使います。
    

    
    LimitInternalRecursion は内部リダイレクトや
    サブリクエストが無限ループに陥ったときのサーバクラッシュを防ぎます。
    普通、そのようなループは設定に失敗したときに発生します。
    

    
    このディレクティブは、リクエスト毎に評価される、二つの違う限界値を
    設定します。最初の number は、起こり得る
    内部リクエストの最大値を設定します。二つめの number は
    サブリクエストが入れ子にできる深さを設定します。number を
    一つだけ指定したときは、両方の限界値にその値が設定されます。

    許容する  HTTP リクエストメッセージボディのサイズに制限をかけることができます。
    クライアントのリクエストがその制限値を越えていれば、
    サーバはリクエストを処理せずにエラーを返します。
    普通のリクエストメッセージボディのサイズは、リソースの種類や
    許可されているメソッドによって大きく変わります。
    CGI スクリプトは、よく情報を受信するために
    メッセージボディを使います。
    PUT メソッドの実装は、このディレクティブの値として
    少なくともあるリソースに対してサーバが受け付けようとする
    表現の大きさほどの値を必要とします。
    

    
    このディレクティブは、

    LimitRequestBody ディレクティブは、
    サーバ管理者が HTTP リクエスト中において許可するリクエストヘッダフィールド数を
    指定します。
    サーバはこの値には通常のクライアントからのリクエストに含まれるであろう
    フィールドの数より大きな値が必要とします。
    クライアントにより使われた要求ヘッダーフィールドの数が
    20 を超えることはほとんどありませんが、
    これは種々のクライアントの実装によって変わり、
    詳細なコンテントネゴシエーションをするためのブラウザの設定までにも
    影響されることがあります。
    オプションの HTTP 拡張はリクエストヘッダフィールドを使って表される場合が

    <Location> ディレクティブは、
    URL により中に書かれたディレクティブの適用範囲を制限します。
    <Directory>
    ディレクティブと似ていて、
    </Location> ディレクティブで終了する
    サブセクションを開始します。
    <Location> セクションは、
    <Directory> セクションと
    .htaccess の読み込みの後、
    <Files> セクションを
    適用した後に、設定ファイルに現れた順に処理されます。
    

    
    <Location> セクションは
    完全にファイルシステムと関連せずに動作します。このことから導かれる
    結果にはいくつか注意する点があります。最も重要なものは、
    ファイルシステムの位置へのアクセス制御に <Location> ディレクティブを使うべきではない
    ということです。複数の URL がファイルシステムの同じ位置にマップされる
    可能がありますので、そのようなアクセス制御は回避されてしまう可能性が
    あります。
    

    
    いつ <Location> を使うか
    

    
    <Location> ディレクティブは
    ファイルシステム外のコンテンツにディレクティブを適用するときに
    使用してください。ファイルシステムに存在するコンテンツに対しては、
    <Directory> と <Files> を使ってください。
    例外は、<Location /> で、これはサーバ全体に対して
    設定を適用する簡単な方法です。
    
    
    

    
    全ての (プロキシ以外の) リクエストに対し、
    URL は /path/ という、
    接頭辞 http://servername を含まない形でマッチします。
    プロキシリクエストの場合には、scheme://servername/path
    という接頭辞を含む形でマッチし、接頭辞を含めて指定する必要があります。
    

    
    URL にはワイルドカードを利用することができます。
    ? は任意の一文字、* は任意の文字列にマッチします。
    どちらのワイルドカードも URL パス中の / にはマッチしません。
    

    
    ~ という文字を追加することで、正規表現を
    利用することもできます。
    例えば:
    

    
    
      <Location ~ "/(extra|special)/data">
    
    

    
    は URL に /extra/data か /special/data という文字列が
    含まれている場合にマッチします。
   <LocationMatch> ディレクティブは
    <Location> の正規表現
    版とまったく同じ動作をします。
    

    
    <Location> 機能は、SetHandler ディレクティブと
    組合わせて利用すると特に便利です。
    例えば、example.com のブラウザからのみステータスの参照を有効にしたければ、
    次のようにすれば良いでしょう。
    

    
    
      <Location /status>
    
      
        SetHandler server-status
    
        Order Deny,Allow
    
        Deny from all
    
        Allow from .example.com
    
          
      </Location>
    
    


    / (スラッシュ) に関する注
    
    
    スラッシュ文字は、URL 内に現れる場所に応じて変化する
    特別な意味を持っています。
    ファイルシステムにおいて利用する場合には複数のスラッシュでも一つの
    スラッシュとして扱われることが多いですが、
    (すなわち、/home///foo は
    /home/foo と同じといったように)
    URL においては必ずしもそうなるわけではありません。
    <LocationMatch>
    ディレクティブや正規表現を利用した
    <Location> ディレクティブで、
    複数のスラッシュにマッチさせたいときには、明示的に記述する
    必要があります。
    

    
    例えば、<LocationMatch ^/abc> は、
    /abc というリクエスト URL にマッチしますが、
    //abc というリクエスト URL にはマッチしません。
    (正規表現でない) <Location>
    ディレクティブは、
    proxy リクエストに対して利用する際には同様の振る舞いをしますが、
    (正規表現でない) <Location> を proxy
    でないリクエストに対して利用する際には、
    一つのスラッシュで複数のスラッシュにマッチします。
    例えば、<Location /abc/def> と指定し、
    /abc//def というリクエストがあれば、
    マッチすることになります。

    NameVirtualHost ディレクティブは、
    名前ベースのバーチャルホストの設定を行ないたい場合に
    必要となるものです。
    

    
    addr にはホスト名を指定できますが、
    常に IP アドレスを指定するのが推奨されます。
    例えば、
    

    
    
      NameVirtualHost 111.22.33.44
    
    

    
    NameVirtualHost ディレクティブは、
    名前ベースのバーチャルホストを
    利用してリクエストを受け付ける IP アドレスを指定します。
    これは、普通は名前ベースのバーチャルホストアドレスです。
    ただし、ファイアーウォールや他のプロキシがリクエストを受け付け、
    違う IP アドレスのサーバにフォワードするという場合は、
    リクエストを提供したいマシン上の物理インターフェースの
    IP アドレスを指定する必要があります。
    複数のアドレスで複数の名前ベースのバーチャルホストを指定する場合は
    各アドレスに対してディレクティブを書いてください。
    

    
    中
    
      
    「主サーバ」や、どの _default_ サーバも、
      NameVirtualHost で指定した IP アドレスへのリクエスト
      を処理することはありません (なぜか
      NameVirtualHost を
      指定したけどそのアドレスに VirtualHost を定義しなかった場合を除く)。
    
    
    

    
    名前ベースのバーチャルホストにポート番号を指定することも可能です。
    例えば
    

    
    
      NameVirtualHost 111.22.33.44:8080
    
    

    
    IPV6 のアドレスは次の例のように角括弧で囲む必要があります:
    
 
    
    
      NameVirtualHost [2001:db8::a00:20ff:fea7:ccea]:8080
    
    

    
    すべてのインタフェースへのリクエストを受け取るようにするためには、
    引数として * を使います。
    

    
    
      NameVirtualHost *
    
    

    
    <VirtualHost> ディレクティブの引数
    
      
    <VirtualHost> ディレクティブの引数は NameVirtualHost ディレクティブの引数に正確に
      合っている必要があることに注意してください。
    

      
    
        NameVirtualHost 1.2.3.4
    
        <VirtualHost 1.2.3.4>

    Options ディレクティブは、特定のディレクトリに対して
    どの機能が使用可能かを制御します。
    

    
    option を Noneに指定すると、
    特別な機能は全て無効になります。
    また、以下の示す 1 個以上のものを指定できます。
    

    
    
      
    All
    

      
    MultiViews を除いた全ての機能が有効となります。
      これがデフォルトです。
    

      
    ExecCGI
    

      
    
      mod_cgi による CGI スクリプトの実行を許可します。
    

      
    FollowSymLinks
    

      
    
      サーバが、このディレクトリ内でシンボリックリンクをたどれるようにします。
      
    サーバがシンボリックリンクをたどる場合でも、
      <Directory> セクションに
      マッチさせるための
      パス名は変更されません。
    
      
    <Location> 内に
      このオプションを指定しても無視されることに
      注意してください。
    
      
    このオプションを省略したからといってセキュリティの強化にはなりません。
      なぜなら symlink の検査はレースコンディションを引き起こす可能性があり、
      そのため回避可能になるからです。
    
      
    

      
    Includes
    

      
    
      mod_include が提供する SSI を有効にします。
    

      
    IncludesNOEXEC
    

      
    
      SSI は有効になりますが、#exec コマンド と #exec CGI は無効になります。
      ただし、#include virtual により、ScriptAlias されたディレクトリで
      CGI を実行することは可能です。
    

      
    Indexes
    

      
    
      もし、URL がディレクトリにマップするリクエストであって、
      且つ DirectoryIndex で指定したファイル (例えば、index.html) が
      ディレクトリ内に無ければ、mod_autoindex が
      ディレクトリ内の一覧を整形して返します。
    

      
    MultiViews
    

      
    
      mod_negotiation による
      コンテントネゴシエーション 
      された "MultiViews" を許可します。
    

      
    SymLinksIfOwnerMatch
    

      
    
      シンボリック先のファイルまたはディレクトリが、
      シンボリックリンクの所有ユーザ ID と同じ場合にのみシンボリックリンクを
      たどれるようにします。

      
    注
     
    <Location> 内にこのオプションを
      指定しても無視されます。
    
      
    このオプションはセキュリティの強化にはなりません。
      なぜなら symlink の検査はレースコンディションを引き起こす可能性があり、
      そのため回避可能になるからです。
    
      
    
      
    
    
    

    
    通常、ディレクトリに対して複数の Options が
    適用可能な場合、
    最も近いもの一つのみが適用され、他のものは無視されます。
    複数の指定がマージされるわけではありません。(セクションのマージ方法を参照してください。)
    しかし、すべての Options ディレクティブが + や - 付きで
    指定された場合はオプションの値はマージされます。
    + を頭につければ現在の設定に加えられ、
    - を付ければ現在の設定から削除されます。
    

    
    警告
    
    
    Options で + や
    - のついたものを、つけないものと組み合わせて
    指定する構文は正しい構文ではありませんので、期待する結果に
    ならないことがあります。
    
    
    

    
    例えば、+ や - を利用しない場合は:
    

    
    
      <Directory /web/docs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
      
    
      <Directory /web/docs/spec>
    
      
        Options Includes
    
          
      </Directory>
    
    

    
    /web/docs/spec というディレクトリには、
    Includes だけが適用されます。
    しかし、2 番目の Options で + や - を利用してみると:
    
 
    
    
      <Directory /web/docs>
    
      
        Options Indexes FollowSymLinks
    
          
      </Directory>
    
      
    
      <Directory /web/docs/spec>
    
      
        Options +Includes -Indexes
    
          
      </Directory>
    
    

    
    /web/docs/spec というディレクトリには、 FollowSymLinks と
    Includes が適用されます。
    

    
    注
    
      
    -IncludesNOEXEC もしくは
      -Includes を指定すると、
      前の設定がどのようになっていようとも SSI は無効となります。
    
    
    

    
    どのような設定もされていなければ、デフォルトでは All に
    なります。

    使われます。レジストリキーが見つからないときは、Apache は Script
    オプションが指定されたときの動作に戻ります。
    

    
    セキュリティ
     
    
    ScriptInterpreterSource Registry を ScriptAlias されたディレクトリで使うときは
    注意してください。Apache はそのディレクトリ中のすべてのファイルを
    実行しようとします。Registry という設定は通常は実行されない
    ファイルに対して望ましくないプログラムの実行が発生する可能性があります。
    例えば、ほとんどの Windows システムで、
    .htm ファイルのデフォルトの「開く」コマンドは
    Microsoft Internet Explorer を実行しますので、スクリプトに指定された
    ディレクトリにある .htm ファイルへのリクエストはサーバの
    バックグラウンドでブラウザを実行することになります。これは、一分内くらいで
    システムをクラッシュさるための良い方法です。
    
    
    

    
    Apache 2.0 から導入されたオプション Registry-Strict は
    Registry と同じことを行ないますが、サブキー
    Shell\ExecCGI\Command のみを使います。
    ExecCGI キーは普通に使われるキーではありません。Windows 
    レジストリに手動で設定する必要がありますので、システムでの偶発的なプログラムの
    実行を防ぐことができます。

    そうでないと、エラーが起こったときに連絡をすることができなくなって

    ServerName ディレクティブは、
    サーバが自分自身を示すスキーム名、ホスト名とポート番号を設定します。
    これは、リダイレクトする URL を生成する際に利用されます。
    例えば、ウェブサーバを動かしているマシンは simple.example.com
    で、DNS のエイリアス www.example.com もあるときに、
    ウェブサーバが後者として認識されて欲しいときは、以下のようにディレクティブを
    使います。
    

    
    
      ServerName www.example.com:80
    
    

    
    ServerName が指定されていないときは、
    サーバは IP アドレスから逆引きを行なうことでホスト名を知ろうとします。
    ServerName にポートが指定されていないときは、
    サーバはリクエストが来ている
    ポートを使います。最高の信頼性と確実性をもたらすためには、
    ServerName を使ってホスト名とポートを明示的に
    指定してください。
    

    
    名前ベースのバーチャルホスト
    を利用している場合、<VirtualHost> セクション内の
    ServerName はこのバーチャルホストにマッチするために
    何がリクエストの Host: ヘッダに現れる必要があるのかを指定します。
    

    
    SSL を処理するデバイス、例えばリバースプロクシやロードバランサや
    SSL 処理軽減アプライアンスの裏側でサーバが稼動する場合もあるでしょう。
    そういった場合では、クライアントが接続するときに使う
    https:// スキームとポート番号を ServerName
    ディレクティブで指定して、自己参照 URL が正しく生成できるようにします。

    多くの状況で Apache は自己参照 URL、すなわち
    同じサーバを指す URL、を作成する必要があります。
    UseCanonicalName On の場合は、ServerName ディレクティブで指定されている
    ホスト名とポート番号を使って、その正規名 (自己参照の名前) を生成します。
    この名前は、すべての自己参照 URL で使われますし、CGI の 
    SERVER_NAME と SERVER_PORT でも使われます。
    

    
    UseCanonicalName Off の場合、
    クライアントがホスト名とポートを指定したときには、
    それらを元に自己参照 URL を作成します (指定がなかったときは
    上の定義と同様にして正規名を解決します)。
    これらの値は名前ベースの
    バーチャルホストを実装で使われているのと同じ値で、
    同じクライアントで取得できる値になっています。
    CGI 変数 SERVER_NAME と SERVER_PORT 
    もクライアントから与えられた値から作成されます。
    

    
    このような挙動が便利な例は、イントラネットのサーバで www
    のような短い名前でユーザがマシンに接続するときです。
    ユーザの入力で短いホスト名が使われていて、URL が最後のスラッシュ無しの
    ディレクトリになっている http://www/splat のようなとき、
    Apache はリクエストを http://www.domain.com/splat/ 
    へリダイレクトします。
    認証をするように設定していると、この場合
    ユーザは 2 回認証をしなければならなくなります (www に
    対して 1 回、www.domain.com に対してもう 1 回 -- 
    詳細は この話題の
    FAQ を参照してください)。
    しかし UseCanonicalName が Off になっていると、
    Apache は http://www/splat/ にリダイレクトします。
    

    
    三つ目のオプション UseCanonicalName DNS は、
    大規模な IP ベースのバーチャルホスティングで、
    Host: ヘッダを提供しない古いクライアントを
    サポートする場合を想定しています。
    このオプションでは Apache は、クライアントが接続した IP アドレスに対して
    DNS の逆引きを行なって、自己参照 URL を作成します。
    

    
    警告
    
    
    CGI が SERVER_NAME に関して何らかの前提条件を
    仮定しているときには、このオプションの設定によっては動作しなく
    なるかもしれません。クライアントは実質的にはホスト名として
    何でも望みの値を指定することができます。CGI が
    SERVER_NAME を使って自己参照 URL を作成することしかしない
    場合は、どの設定を行なっても大丈夫なはずです。

    説明:特定のホスト名や IP アドレスのみに適用されるディレクティブを
囲む
    

    構文:<VirtualHost
    addr[:port] [addr[:port]]
    ...> ... </VirtualHost>

    モジュール:core
    

    
    
    <VirtualHost> 及び
    </VirtualHost> は、
    特定のバーチャルホストに対してのみ適用されるディレクティブ群を括る
    ために使われます。
    バーチャルホストコンテキストで許可される全てのディレクティブを指定可能です。
    サーバが、指定されたバーチャルホストにあるドキュメントへの
    リクエストを受け付けた場合、
    <VirtualHost> セクションの中にある
    ディレクティブが適用されます。
    Addrは、次のものが利用できます:
    

    
      
      
    • バーチャルホストの IP アドレス
      • 

      
    • バーチャルホストの IP に対応する完全なドメイン名 (非推奨)
      • 

      
    • NameVirtualHost * と共に使われる、
      すべての IP アドレスにマッチする文字 *
      • 

      
    • IP ベースのバーチャルホストで他のものにマッチしない IP アドレス
      のための文字列 _default_
      • 
    
    

    
    例
    
      <VirtualHost 10.1.2.3>
    
      
        ServerAdmin webmaster@host.example.com
    
        DocumentRoot /www/docs/host.example.com
    
        ServerName host.example.com
    
        ErrorLog logs/host.example.com-error_log
    
        TransferLog logs/host.example.com-access_log
    
          
      </VirtualHost>
    
    
 
    
    IPv6 アドレスはオプションのポート番号の指定と区別するために、
    角括弧で括って指定する必要があります。次は IPv6 の例です:
    

    
    
      <VirtualHost [2001:db8::a00:20ff:fea7:ccea]>
    
      
        ServerAdmin webmaster@host.example.com
    
        DocumentRoot /www/docs/host.example.com
    
        ServerName host.example.com
    
        ErrorLog logs/host.example.com-error_log
    
        TransferLog logs/host.example.com-access_log
    
          
      </VirtualHost>
    
    

    
    各々のバーチャルホストにはそれぞれ違う IP アドレス、ポート番号
    もしくはホスト名に対応する必要があり、
    1 番目の場合には複数のアドレスで IP パケットを受信できるように
    サーバマシンを設定しなければなりません。
    (もし、マシンが複数のネットワークインターフェースを持たない場合は、
    (OSがサポートしていれば) ifconfig alias コマンドにより
    達成できます)。
    

    
    注意点
    
    
    <VirtualHost> は Apache が Listen する
    IP アドレスには影響を与えません。
    Listen を
    使って Apache が正しいアドレスを listen するように設定する必要があります。
    
    
    

    
    IP ベースのバーチャルホストを使っている場合は、特別な名前
    _default_ を指定することができます。その場合は
    そのバーチャルホストは他のバーチャルホストで明示的に挙げられていない
    すべての IP アドレスにマッチします。_default_ バーチャルホストが無い
    場合に IP がバーチャルホストで指定されたものにマッチしないときは、
    VirtualHost セクションの外のすべての定義からなる「主」サーバ設定が
    使われます。(ただし、NameVirtualHost ディレクティブにマッチする
    すべての IP アドレスは「主」サーバ設定も _default_ バーチャルホストも
    使わないことに注意してください。詳しくは ネームベースのバーチャルホスト を
    参照してください。)
    

    
    :port といった形式で記述することにより、
    マッチさせるポートを変更可能です。
    この指定をしない場合には、主サーバ設定における
    一番最後に Port で指定されたポートが
    デフォルトとなります。
    :* を指定することにより、
    アドレス上の全てのポートにマッチします。(_default_ のときは
    これを使うことが推奨されています。)
    

    
    <VirtualHost> ブロックごとに
    ServerName を指定すべきです。
    もしなければ、メインサーバ設定の
    ServerName
    が継承されます
    

    
    セキュリティ
    
    
    サーバーを起動した以外のユーザがログファイルが保管されるディレクトリに
    書き込み可能なときになぜセキュリティが破られる可能性があるかの詳細は

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:DBM ファイルを用いたユーザ認証
    

    ステータス:Extension
    

    モジュール識別子:authn_dbm_module
    

    ソースファイル:mod_authn_dbm.c
    

    互換性:Apache 2.1 以降
    

    概要
    

    
    本モジュールは mod_auth_digest や
    mod_auth_basic といった認証フロントエンドに対して、
    dbm パスワードファイル内からのユーザ検索による
    ユーザ認証機能を提供します。似たような機能は mod_authn_file
    でも提供されています。
    

    
    mod_auth_basic や mod_auth_digest
    を使用する際には、このモジュールは
    AuthBasicProvider や
    AuthDigestPrivider
    で dbm と指定することで起動されます。

    AuthDBMType ディレクティブ
    

    

    説明:パスワードを保存するために必要なデータベースファイルの種類を
設定する
    

    構文:AuthDBMType default|SDBM|GDBM|NDBM|DB
    

    デフォルト:AuthDBMType default
    

    コンテキスト:ディレクトリ, .htaccess
    

    上書き:AuthConfig
    

    ステータス:Extension
    

    モジュール:mod_authn_dbm
    

    
    
    パスワードを保存するために使用するデータベースファイルの種類を
    設定します。デフォルトのデータベースの種類はコンパイル時に決まります。
    他の種類のデータベースが使用可能かどうかも コンパイル時の設定に依存します。
    

    
    パスワードファイルを作成するのに使用するプログラムが同じ種類のデータベースを
    使用するように設定することは非常に重要です。

    AuthDBMUserFile ディレクティブ
    

    

    説明:認証用のユーザとパスワードのリストを保持している
データベースファイル名を設定する
    

    構文:AuthDBMUserFile file-path
    

    コンテキスト:ディレクトリ, .htaccess
    

    上書き:AuthConfig
    

    ステータス:Extension
    

    モジュール:mod_authn_dbm
    

    
    
    AuthDBMUserFile ディレクティブは
    認証用のユーザとパスワードのリストを保持している DBM ファイルの
    名前を設定します。File-path はユーザファイルへの
    絶対パスです。
    

    
    ユーザファイルのキーはユーザ名です。ユーザに対して返される値は
    暗号化されたパスワードで、その後に、コロンに続いて任意のデータが
    続いていることもあります。コロンとその後のデータはサーバは
    無視します。
    

    
    セキュリティ
    
      
    AuthDBMUserFile  は、
      ウェブサーバのドキュメントツリーの外側に保管するようにしてください。
      保護しようとしているディレクトリ以下には
      置かないで下さい。
      そうしないとクライアントが AuthUserFile を
      ダウンロードできてしまいます。
    
    
    

    
    重要な互換性に関する注意: apache module の dbmopen の実装は
    文字列が NULL で終わっていることに依存するのではなく、DBM データストラクチャ
    のハッシュ値の文字列の長さを読み取ります。Netscape ウェブサーバなど、
    アプリケーションの中には文字列が NULL で終わっていることに依存している
    ものがあります。ですから、異なるアプリケーション間での DBM ファイルの
    使用に問題がある場合は、これが原因になっている可能性があります。
    

    
    Apache には dbmmanage という
    perl スクリプトが含まれています。このプログラムを使ってこの
    モジュールが使用する DBM フォーマットのパスワードファイルを作成したり
    更新したりすることができます。

    Açıklama:Unix ls veya Win32 dir kabuk komutunun
yaptığı gibi dizin içeriğini listeler.
    

    Durum:Temel
    

    Modül Betimleyici:autoindex_module
    

    Kaynak Dosyası:mod_autoindex.c
    

    Özet
    

      
    Bir dizin içerik dosyası iki kaynaktan gelebilir:
    

    
      
      
    • Bu dizinde bulunan ve genellikle index.html
        adında bir dosya olarak. Kullanılan dosyanın veya dosyaların ismi
        DirectoryIndex yönergesi ile
        belirlenir ve mod_dir tarafından denetlenir.
      • 

      
    • Kullanıcı tarafından böyle bir dosya sağlanmadığı takdirde dizin
        içerik listesini sunucu üretir. Diğer yönergeler bu listenin biçemini
        belirler. Listede gösterilen dosya türü simgeleri AddIcon, AddIconByEncoding ve AddIconByType yönergeleri ile
        belirlenir. Bunlar mod_autoindex tarafından
        denetlenir.
      • 
    
    

    
    İki işlev birbirinden ayrı tutulmuştur, böylece kendiliğinden içerik
      listesi üretimi tamamen iptal edilebilir (veya değiştirilebilir).
    

    
    Kendiliğinden içerik listesi üretimi Options +Indexes ile
      etkin kılınabilir. Daha fazla bilgi için Options yönergesinin açıklamasına bakınız.
    

    
    IndexOptions yönergesi
      FancyIndexing
      seçeneği ile kullanılmışsa sütun başlıkları listenin sıralamasını
      sütundaki sıralamaya göre değiştirecek hiper bağlar haline getirilir
      (süslü liste). Aynı başlığa peşpeşe tıklamak suretiyle sıralamayı
      büyükten küçüğe veya tersine değiştirebilirsiniz. Bu sütun başlığı
      bağlarının oluşturulması IndexOptions yönergesi SuppressColumnSorting seçeneği ile kullanılarak
      engellenebilir.
    

    
    Boyuta göre sıralamada daima dosyanın asıl boyutuna bakılır.
      Dolayısıyla ikisi de "1K" olarak gösterilen iki dosyadan 1010 baytlık
      olanı küçükten büyüğe sıralamada 1011 baytlıktan önce
      gösterilecektir.

    Sütun Sıralamada Sorgu Seçenekleri
    
    

    
    İstemciye, dizin içeriğini listelerken neleri hangi sırada
      listeleyeceğini belirleyebilmesi için içerik üzerinde biraz denetim
      sağlayabileceği çeşitli sorgu dizgesi bileşenleri sağlanmıştır.
      Çıktı üzerinde kullanıcı denetimini tamamen ortadan kaldırmak için
      IndexOptions yönergesinin
      IgnoreClient
      seçeneği kullanılabilir.
    

    
    Sütun sıralama başlıklarının her biri hedefi kendisi olan birer hiper
      bağ olup aşağıda sıralanan sorgu seçeneklerini kullanırlar. Bu
      seçeneklerin her biri her dizin içerik listesi isteğine eklenebilir.
    

    
      
      
    • C=N dizini dosya adına göre sıralar
      • 

      
    • C=M dizini son değişiklik zamanına ve ardından dosya
        ismine göre sıralar.
      • 

      
    • C=S dizini boyuta ve ardından dosya adına göre
        sıralar
      • 

      
    • C=D dizini açıklamaya ve ardından
        dosya adına göre sıralar.
      • 

      
    • O=A artan sıralama uygulanır.
      • 

      
    • O=D  azalan sıralama uygulanır.
      • 

      
    • F=0 listeleme basit listeleme biçiminde yapılır
        (FancyIndexing seçeneği ile etkinleştirilen biçimde
        değil)
      • 

      
    • F=1 listeleme FancyIndexing seçeneği ile
        etkinleştirilen biçimde yapılır
      • 

      
    • F=2 listeleme FancyIndexing ve
        HTMLTable seçeneği
        ile etkinleştirilen biçimde yapılır.
      • 

      
    • V=0 sürüme göre sıralama iptal edilir.
      • 

      
    • V=1 sürüme göre sıralama etkin
        kılınır.
      • 

      
    • P=kalıp sadece belirtilen
        kalıp ile eşleşen dosyalar istelenir.
      • 
    
    

    
    P=kalıp sorgu seçeneğinin normalde IndexIgnore yönergesi işleme
      sokulduktan sonra değerlendirildiğine ve dosya isimlerinin diğer
      kendiliğinden içerik listeleme koşullarının konusu olmaya devam ettiğine
      dikkat ediniz. mod_autoindex modülündeki Sorgu
      Seçenekleri çözümleyicisi tanımadığı bir seçeneğe rastlar rastlamaz
      işlemi durdurur. Sorgu Seçenekleri yukarıda belirtilene uygun olarak iyi
      biçimli olmak zorundadır.
    

    
    Aşağıdaki basit örnekte sorgu seçeneklerinin kullanımı gösterilmiştir.
      Son satırda bulunan "submit" düğmesindeki tanınmayan "X" girdisine
      dikkat ediniz. "X=Göster" girdisi tüm seçenekler işlendikten sonra
      mod_autoindex tarafından son argüman olarak ele
      alınacak ve çözümleme işlemi o noktada duracaktır.
    

    
    Örnek
    <form action="" method="get">
   <input type="text" name="P" value="*" /> ile eşleşen
   <select name="C">
       <option value="N" selected="selected">isme</option>
       <option value="M"> değişiklik tarihine</option>
       <option value="S"> boyuta</option>

   <select name="V">
       <option value="0" selected="selected">normal</option>

      seçeneği buna 6 bayt daha ekler; IndexOptions SuppressSize
      seçeneği 7 bayt, IndexOptions SuppressLastModified seçeneği ise 19 bayt
      ekler. Böylece en fazla 55 karakterlik öntanımlı sütun genişliğine
      ulaşılabilir.
    

    
    dosya kısmî dosya ismi içerebileceğinden çok kısa dosya ismi
      belirtilmesi yüzünden istemeden de olsa başka dosyalarla
      eşleşebileceğini unutmayın. Örneğin, le.html doğrudan
      le.html ile eşleşebileceği gibi example.html
      ile de eşleşecektir. Şüpheli durumların ortaya çıkabileceği durumlarda
      mümkün olduğunca dosya isminin tamamını kullanın ve saptanan ilk
      eşleşmenin kullanılacağını aklınızdan çıkarmayın ayrıca,
      AddDescription listesini de uygun şekilde sıralayın.
    

    
    Açıklama sütununun öntanımlı genişliği geçersiz kılınabilir hatta
      sınırsız açıklama uzunluğu atanabilir. Bu konu için IndexOptions yönergesinin DescriptionWidth
      seçeneğinin açıklamasına bakınız.
    

    
    Önemli
    
      
    AddDescription ile tanımlanan açıklama metni
        HTML etiketleri ve karakter öğeleri içerebilir. Eğer açıklama
        sütununun genişlik sınırlamasından dolayı bir HTML etiketinin içeriği
        kırpılırsa bu durum dizin listesinin kalanını etkileyebilir (örneğin,
        kalın gösterim listenin kalanına yayılabilir).
    
    
    

    
    Yol bilgisi içeren değiştirgeler
    
      
    Mutlak yollar henüz desteklenmemetedir ve çalışma anında hiçbir şeyle
        eşleşmeyeceklerdir. Normalde sadece htaccess bağlamında kullanılan,
        göreli yol bilgisi içeren değiştirgeler, kısmi dizin isimleriyle
        eşleşmemeleri için örtük olarak '*/' öneki alırlar.

    HeaderName HEADER.html
    


    
    
      
    HeaderName and ReadmeName yönergelerinde
        dosya-ismi artık içeriği listelenecek dizine
        erişmek için kullanılan bir göreli URL yolu olarak ele alınmaktadır.
        Eğer dosya-ismi bir bölü çizgisi ("/") ile
        başlıyorsa DocumentRoot
        yönergesinde belirtilen dizine göre belirtildiği varsayılır.

    dosya-ismi,  içerik türü text/*
        (text/html, text/plain gibi) olan bir belge
        olarak çözümlenmelidir. Yani, aşağıdaki örnekteki gibi betiğin asıl
        dosya türü text/html olarak imlenmişse
        dosya-ismi bir CGI betiğinin ismi bile
        olabilir:

    Options ile
        MultiViews etkin kılınmışsa dosyaya içerik dili uzlaşımı da
        uygulanabilir. dosya-ismi ile belirtilen dosya
        text/html türünde durağan bir belge (bir CGI betiği
        değil) ise ve options ile
        Includes ve IncludesNOEXEC seçeneklerinden
        biri belirtilmişse dosya bir SSI sayfası olarak ele alınır
        (mod_include belgesine bakınız).
    
    
    

    
    Eğer yönergede belirtilen dosya bir HTML belge gibi başlıyorsa
      (<html>, <head>, vs.) ve bu etiketlerin yinelenmemesini
      istiyorsanız IndexOptions +SuppressHTMLPreamble ataması yapmanız
      gerekecektir.

    IndexOptions yönergesi dizin içerik listesinin
      davranışını belirler. seçenek olarak şunlar
      belirtilebilir:
    

    
    
      
    AddAltClass
    
      
    IndexOptions HTMLTable etkin ve bir
        IndexStyleSheet tanımlı olduğunda dizin listesi
        tablosunun her satırına fazladan bir CSS sınıfı bildirimi ekler.
        Tablonun her satırına uygulanmaması için standart even ve
        odd sınıfları yerine even-ALT ve
        odd-ALT bildirimleri kullanılabilir. Burada
        ALT ya bir dosya biçimiyle ilişkili standat bir alt
        dizgesidir ya da AddAlt* yönergeleriyle tanımlanan bir
        alt dizgesidir.
      
    

      
    Charset=karakter-kümesi
    

      
    Charset seçeneği üretilen sayfa için bir karakter
        kümesi belirtebilmenizi sağlar. Dizinin bulunduğu dosya sisteminin
        karakter kodlamasına bağlı olarak öntanımlı değeri Windows ve Mac OS
        X'te UTF-8, diğerlerinde ISO-8859-1’dir (İlgili
        dosya sisteminin Unicode dosya isimleri kullanıp kullanmamasına
        bağlıdır).

      
    IndexOptions Charset=UTF-8
    

      
    

      
    DescriptionWidth=[n | *]
    

      
    DescriptionWidth seçeneği üretilen sayfada açıklama
        sütununun genişliğini sizin belirleyebilmenizi sağlar. Bu seçenek
        kullanılmadığında veya -DescriptionWidth olarak
        belirtildiğinde uygun genişliği mod_autoindex
        hesaplar.
    

        
    DescriptionWidth=n ile açıklama sütununun
          genişliği n baytla sınırlanır.
    

        
    DescriptionWidth=* ile açıklama sütununun genişliği en
          uzun açıklama metni sığacak şekilde arttırılır.
    

        
    Sütun genişliğinin sabitliği nedeniyle metnin
          kırpılmasından kaynaklanan sorunlar için AddDescription yönergesinin
          açıklamasına bakınız.
    

      
    FancyIndexing
    

      
    Dizin içerik listesi süslü olur.
    

      
    FoldersFirst
    

      
    Bu seçenek etkin kılındığında dizin içerik listesinde alt dizinler
        dosyalardan önce listelenir. Listelemede genel olarak iki bileşen
        vardır: Alt dizinler ve dosyalar. Her biri kendi arasında sıraya
        dizilir ve alt dizinlerin tamamı dosyalardan önce gösterilir. Örneğin
        sıralama isme göre azalan sırada yapılıyorsa ve
        FoldersFirst etkinse Zed dizini listede
        Beta dizininden ve Gamma ve
        Alpha dosyalarından önce yer alacaktır. Bu
        seçenek sadece FancyIndexing  seçeneği etkinse etkili
        olacaktır.
    

      
    HTMLTable
    

      
    FancyIndexing
        seçeneği ile birlikte süslü listeleme için basit bir tablo oluşturur.
        UTF-8'in etkin olduğu platformlarda gereklidir. Bununla birlikte,
        Linux, WinNT gibi sağdan sola veya soldan sağa yazım yönünün değiştiği
        platformlarda dosya isimleri ve açıklamalar için bu özellikle gerekli
        olabilir.
    

      
    IconsAreLinks
    

      
    Bu seçenek FancyIndexing  seçeneği ile birlikte süslü
        listelemede dosya simgesini dosyaya bir hiper bağ haline getirir.
    

      
    IconHeight[=benek-sayısı]
    

      
    Bu seçeneğin varlığı IconWidth seçeneği ile
        kullanıldığında dosya simgesinin img etiketinin
        height ve width özniteliklerini içermesine
        sebep olur. Böylece tarayıcının tüm simgelerin yüklenmesini beklemeden
        sayfa yerleşimi için bir ön hesaplama yapabilmesi mümkün olur. Seçenek
        bir değer belirtilmeksizin kullanıldığında Apache http tarafından
        atanmış standart simge yüksekliği öntanımlıdır. Bu
        seçenek sadece FancyIndexing  seçeneği etkinse etkili
        olacaktır.
    

      
    IconWidth[=benek-sayısı]
    

      
    Bu seçeneğin varlığı IconHeight seçeneği ile
        kullanıldığında dosya simgesinin img etiketinin
        height ve width özniteliklerini içermesine
        sebep olur. Böylece tarayıcının tüm simgelerin yüklenmesini beklemeden
        sayfa yerleşimi için bir ön hesaplama yapabilmesi mümkün olur. Seçenek
        bir değer belirtilmeksizin kullanıldığında Apache httpd tarafından
        atanmış standart simge genişliği öntanımlıdır.
    

      
    IgnoreCase
    

      
    Bu seçenek etkin kılındığında isimler harf büyüklüğüne duyarsız
        sıralanır. Örneğin, isme göre artan sıralamada IgnoreCase
        etkinse Zeta dosyası alfa dosyasından sonra listelenir (Dikkat: GAMMA
        daima gamma’dan önce listelenir.)
    

      
    IgnoreClient
    

      
    Bu seçenek mod_autoindex’in listenin sıralanmasına
        etki edenler dahil tüm sorgu değişkenlerini yoksaymasına sebep olur
        (örtük olarak SuppressColumnSorting uygulanır).
    

      
    NameWidth=[n | *]
    

      
    NameWidth seçeneği dosya ismi sütunu için bir
        genişlik belirtebilmenizi mümkün kılar.
    

      
    Hiç belirtilmediğinde veya -NameWidth biçeminde
        belirtildiğinde mod_autoindex uygun genişliği kendisi
        hesaplayacaktır, fakat en fazla 20 karakter olabilir.
    

      
    NameWidth=n ile sütun genişliği
        n bayt genişlikte sabitlenir.
    

      
    NameWidth=* olduğunda ise sütun genişliği en geniş
        satırın sığacağı kadar arttırılır.
    

      
    ScanHTMLTitles
    

      
    Bu seçenek süslü listeleme için HTML belgelerden sayfa başlığının
        okunmasını sağlar. Dosya için AddDescription ile bir açıklama tanımlanmımışsa Apache
        httpd belgenin title etiketinin içeriğini okuyacaktır. Bu
        seçenek işlemciyi ve diski fazla meşgul eder.
    

      
    ShowForbidden
    

      
    Alt istek HTTP_UNAUTHORIZED veya
        HTTP_FORBIDDEN döndürdüğünden dolayı normalde gizli olan
        dosyalar bu seçenek belirtilmişse listede gösterilir.
    

      
    SuppressColumnSorting
    

      
    Bu seçenek belirtilmişse Apache, süslü dizin listesinde sütun
        başlıklarını sıralama için hiper bağ haline getirmeyecektir. Sütun
        başlıkları için öntanımlı davranış hiper bağ olmak olup bunlar
        seçilerek dizin listesinin o sütundaki değerlere göre sıralanması
        sağlanır. Bu davranış IndexOptions IgnoreClient ile sağlanmaktadır.
    

      
    SuppressDescription
    

      
    Süslü listelemede dosya açıklamalarının gösterilmesini engeller.
        Öntanımlı olarak hiçbir dosya açıklaması tanımlı değildir, dolayısıyla
        bu seçenek kullanılarak ekran genişliğinden 23 karakterlik yer
        kazanılabilir. Dosya açıklamalarının nasıl belirlendiğini öğrenmek
        için AddDescription
        yönergesinin açıklamasına bakınız. Ayrıca, açıklama sütununun
        genişliğini ayarlayan DescriptionWidth dizin listeleme seçeneğine de
        bakınız. Bu seçenek sadece
        FancyIndexing
        seçeneği etkinse etkili olacaktır.
    

      
    SuppressHTMLPreamble
    

      
    Eğer dizin aslında HeaderName yönergesi ile belirtilmiş bir dosya içeriyorsa
        modül normal olarak bu dosyanın içeriğinin öncesine HTML başlangıç
        etiketlerini (<html>, <head>,
        vs.) yerleştirir. Bu seçenek bu davranışı iptal ederek modülün dosya
        içeriğinin başlangıcına bir şey eklememesini sağlar. Bu durumda başlık
        dosyasının uygun HTML etiketlerini içermesi gerekir. Böyle bir başlık
        dosyası yoksa normal olarak HTML başlangıç etiketleri üretilir. Eğer
        bir ReadmeName yönergesi
        de belirtilirse ve bu dosya mevcutsa, kapayan
        </body></html> etiketleri de çıktı bulunmaz. Buna
        dayanarak bu etiketleri de sizin koymanız gerekebilir.
    

      
    SuppressIcon
      
    

      
    Süslü dizin listesinde dosya simgelerinin gösterilmesini engeller.
        Son belirtim, süslü dizin listelemede kullanılan pre
        etiketinin içeriğinde img ve hr
        etiketlerinin bulunmasına izin vermediğinden SuppressIcon
        ve SuppressRules seçenekleri birlikte kullanılarak HTML
        3.2 belirtimine uyum sağlanır.
    

      
    SuppressLastModified
    

      
    Süslü dizin listelemede son değişiklik tarihinin gösterilmesi
        engellenir. Bu seçenek sadece
        FancyIndexing
        seçeneği etkinse etkili olacaktır.
    

      
    SuppressRules
      
    

      
    Dizin listelemede hr etiketinin kullanımını engeller.
        Son belirtim, süslü dizin listelemede kullanılan pre
        etiketinin içeriğinde img ve hr
        etiketlerinin bulunmasına izin vermediğinden SuppressIcon
        ve SuppressRules seçenekleri birlikte kullanılarak HTML
        3.2 belirtimine uyum sağlanır. Bu seçenek sadece
        FancyIndexing
        seçeneği etkinse etkili olacaktır.
    

      
    SuppressSize
    

      
    Süslü dizin listelemede dosya boyutunun gösterilmesi engellenir.
       Bu seçenek sadece
        FancyIndexing
        seçeneği etkinse etkili olacaktır.
      
    

      
    TrackModified
      
    

      
    Bu seçenek listelenen dizin için HTTP başlığında
        Last-Modified ve ETag alanlarının dönmesini
        sağlar. Sadece işletim sistemi veya dosya sistemi uygun stat()
        sonuçlarını döndürüyorsa bu geçerlidir. Bazı Unix sistemleri ve
        OS/2'nin JFS'si ile Win32’nin NTFS’i böyledir. Ancak OS/2 ve Win32 FAT dosya
        sistemleri böyle değildir. Bu özellik etkin kılındığında istemci veya
        vekil HEAD istekleriyle dosya listesindeki değişiklikleri
        izleyebilirler. Yalnız, bazı işletim sistemlerinin yeni ve silinmiş
        dosyaların izini iyi sürdüğü halde dizin içindeki dosyaların boyut ve
        tarih değişikliklerini izlemediklerine dikkat ediniz. Mevcut
        bir dosyanın boyut ve zaman damgasındaki değişiklikler
        Last-Modified başlığının  güncellenmesini tüm Unix
        sistemlerinde sağlamaz. Bu gibi durumlarda bu seçeneğin
        kapalı kalması daha iyidir.
    

      
    Type=MIME-türü
    

      
    Type anahtar sözcüğü üretilen sayfanın MIME içerik
        türünün belirtilebilmesini sağlar. text/html öntanımlıdır.

      
    IndexOptions Type=text/plain
    

      
    

      
    UseOldDateFormat
      (Apache HTTP Sunucusu 2.4.26 ve sonrasında)
    

      
    Last Modified alanı tarafından kullanılan tarih biçemi
        "%Y-%m-%d %H:%M" dikkatsizlik sonucu 2.4.0 sürümünde
        "%d-%b-%Y %H:%M" olarak değişmiştir. Bu seçenekle tarih
        biçemini 2.2 ve öncesindeki biçemiyle kullanabilirsiniz.
    


      
    VersionSort
      
    

      
    VersionSort seçeneği isimlerinde sürüm numarası bulunan
        dosyaların sayısal sıralamaya uygun olarak sıralanmalarını sağlar.
        Normalde sıralama karakter sıralamasına göre yapılır, ardından sürüm
        numaralı dosyalar veya açıklamalar kendi aralarında sayısal sıralamaya
        tabi tutulur.

      
    Örnek:
    
        foo-1.7
    
        foo-1.7.2
    
        foo-1.7.12
    
        foo-1.8.2
    
        foo-1.8.2a
    
        foo-1.12
      
    

      
    Sıfır ile başlalan numaralara ondalık sayı muamelesi yapılır:
    

      
    
        foo-1.001
    
        foo-1.002
    
        foo-1.030
    
        foo-1.04
      
    
      
    

      
    XHTML
    

      
    XHTML seçeneği mod_autoindex’in kodu
        HTML 3.2’ye değil XHTML 1.0’a uygun üretmesini sağlar.
        Bu seçenek sadece
        FancyIndexing
        seçeneği etkinse etkili olacaktır.
    
    
    

   
  
    + veya - Önekli Seçenekler
    
    
    
      
    Çok sayıda IndexOptions yönergesinin
        işlenebileceğine dikkat edin.
    

      
      
      
    • Tek bir dizin için çok sayıda IndexOptions
        yönergesi belirtilmişse bunlar ayrı ayrı değil birlikte ele alınır.
        Yani,

     
      <Directory "/foo">
    IndexOptions HTMLTable
    IndexOptions SuppressColumnsorting
</Directory>
      


      
      yapılandırmasındaki IndexOptions
        yönergeleri
      

     
      IndexOptions HTMLTable SuppressColumnsorting
      


      
      yönergesine eşdeğerdir.
      
      
      • 

      
    • Seçeneklerde + veya - önekleri
        kullanılabilmektedir.
      • 
      
    

      
    + veya - önekli seçeneklere rastlandığında
        bunlar mevcut (üst dizinden miras alınanlar ve/veya önceki atamalar)
        IndexOptions yönergelerine uygulanır. Ancak,
        önek kullanılmamış bir seçeneğe raslandığında, o noktada önceki ve
        miras alınmış bu tür seçenekler iptal edilir. Şu örneği ele
        alalım:
    

     
    IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
IndexOptions +SuppressSize
    


      
    Bunun net etkisi
        IndexOptions FancyIndexing +SuppressSize
        atamasına eşdeğerdir, çünkü öneksiz FancyIndexing
        seçeneği kendinden önceki önekli seçenekleri iptal etmiş fakat hemen
        ardından eklenmelerine izin vermiştir.
    

      
    Belli bir dizine önceki seçenekleri temizleyerek koşulsuz olarak
        tamamen yeni seçenekler atamak istiyorsanız
        IndexOptions yönergesinde seçenekleri
        + veya - öneklerini kullanmadan
        belirtiniz.

    IndexOrderDefault Yönergesi
    

    

    Açıklama:Dizin içerik listesinin öntanımlı sıralamasını belirler.

    

    Sözdizimi:IndexOrderDefault Ascending|Descending
Name|Date|Size|Description
    

    Öntanımlı:IndexOrderDefault Ascending Name
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_autoindex
    

    
    
    IndexOrderDefault yönergesi FancyIndexing seçeneğinin
      etkin olduğu durumda işe yarar. Öntanımlı olarak süslü listelemede dizin
      içeriği dosya ismine göre artan sıralamayla listelenir.
      IndexOrderDefault yönergesi bu öntanımlı
      sıralamanın değiştirilmesini mümkün kılar.
    

    
    IndexOrderDefault yönergesi iki değer alır. İlki
      sıralama yönünü belirtmek üzere Ascending (küçükten büyüğe)
      veya Descending (büyükten küçüğe) olmak zorundadır. İkinci
      değer ise birincil sıralama anahtarını belirtmek üzere
      Name, Date, Size ve
      Description sözcüklerinden biri olmalıdır (anlamları
      sırayla: İsim, Tarih, Boyut, Açıklama). İkincil sıralama anahtarı
      daima artan sıralamayla dosya ismidir.
    

    
    Sütunun tepesindeki sıralama bağını kaldırmak için
      SuppressColumnSorting seçeneğinin yanında, sıralama
      tercihlerinizi geçersiz kılmak için sorgu dizgesine elle sıralama
      seçenekleri eklenmesini engellemek için
      IgnoreClient
      seçeneğini de kullanarak istemcinin listeyi yeniden sıralamasını
      engelleyebilirsiniz.

    IndexStyleSheet Yönergesi
    

    

    Açıklama:Dizin listesine bir biçembent ekler.

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_autoindex
    

    
    
    IndexStyleSheet yönergesi dizin listelemesi için
      kullanılacak biçembent dosyasının ismini belirtmek için kullanılır.
    

    
    IndexStyleSheet "/css/style.css"
    


    
    Bu yönergenin IndexOptions HTMLTable ile birlikte
      kullanılması sonuçlanan HTML dosyasına bir miktar CSS sınıfı ekler.
      Tablonun tamamı indexlist için bir CSS kimliği verir ve
      aşağıdaki sınıflar listenin çeşitli parçalarıyla ilişkilendirilir:
    

    
    SınıfTanım
    

    tr.indexhead
        Liste satırının başlığı
    

    th.indexcolicon and td.indexcolicon
         Simge sütunu
    

    th.indexcolname and td.indexcolname
         Dosya ismi sütunu
    

    th.indexcollastmod and td.indexcollastmod
        Son değişiklik sütunu
    

    th.indexcolsize and td.indexcolsize
        Dosya boyutu sütunu
    

    th.indexcoldesc and td.indexcoldesc
        Açıklama sütunu
    

    tr.breakrow
        Tablonun altınaki yatay çizgi
    

    tr.odd and tr.even
        Tek ve çift satırlar

    ReadmeName Yönergesi
    

    

    Açıklama:Dizin listesinin sonuna yerleştirilecek dosyanın ismini
belirler.
    

    Sözdizimi:ReadmeName dosya-ismi
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:Indexes
    

    Durum:Temel
    

    Modül:mod_autoindex
    

    
    
    ReadmeName yönergesi dizin listesinin sonuna
      eklenecek dosyanın ismini belirler. dosya-ismi ile
      listeye dahil edilecek dosyanın ismi listelenen dizine göreli olarak
      belirtilir. Eğer dosya ismi 2. örnekteki gibi bir bölü çizgisi ile
      başlıyorsa DocumentRoot’a göreli
      belirtildiği varsayılır.
    

    
    # 1. Örnek
ReadmeName FOOTER.html
    


    
    # 2. Örnek
ReadmeName /include/FOOTER.html
    


    
    Ayrıca bu davranışın daha ayrıntılı ele alındığı HeaderName yönergesine de
      bakınız.

    Apache Module mod_session_cookie
    

    

    Available Languages:  en  |

    Description:Cookie based session support
    

    Status:Extension
    

    Module Identifier:session_cookie_module
    

    Source File:mod_session_cookie.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    

    
    Warning
    
      
    The session modules make use of HTTP cookies, and as such can fall
      victim to Cross Site Scripting attacks, or expose potentially private
      information to clients. Please ensure that the relevant risks have
      been taken into account before enabling the session functionality on
      your server.
    
    
    

    
    This submodule of mod_session provides support for the
    storage of user sessions on the remote browser within HTTP cookies.
    

    
    Using cookies to store a session removes the need for the server or
    a group of servers to store the session locally, or collaborate to share
    a session, and can be useful for high traffic environments where a
    server based session might be too resource intensive.
    

    
    If session privacy is required, the mod_session_crypto
    module can be used to encrypt the contents of the session before writing
    the session to the client.
    

    
    For more details on the session interface, see the documentation for
    the mod_session module.
    


    


    top
    

    

    Basic Examples
    

      
    To create a simple session and store it in a cookie called
      session, configure the session as follows:
    

      
    Browser based session
    Session On
SessionCookieName session path=/
    

    

      
    For more examples on how the session can be configured to be read
      from and written to by a CGI application, see the
      mod_session examples section.
    

      
    For documentation on how the session can be used to store username
      and password details, see the mod_auth_form module.

    SessionCookieName Directive
    

    

    Description:Name and attributes for the RFC2109 cookie storing the session
    

    Syntax:SessionCookieName name attributes
    

    Default:none
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_session_cookie
    

    
    
    The SessionCookieName directive specifies the name and
    optional attributes of an RFC2109 compliant cookie inside which the session will
    be stored. RFC2109 cookies are set using the Set-Cookie HTTP header.
    
    

    
    An optional list of cookie attributes can be specified, as per the example below.
    These attributes are inserted into the cookie as is, and are not interpreted by
    Apache. Ensure that your attributes are defined correctly as per the cookie specification.
    
    

    
    Cookie with attributes
    Session On
SessionCookieName session path=/private;domain=example.com;httponly;secure;version=1;

    SessionCookieName2 Directive
    

    

    Description:Name and attributes for the RFC2965 cookie storing the session
    

    Syntax:SessionCookieName2 name attributes
    

    Default:none
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_session_cookie
    

    
    
    The SessionCookieName2 directive specifies the name and
    optional attributes of an RFC2965 compliant cookie inside which the session will
    be stored. RFC2965 cookies are set using the Set-Cookie2 HTTP header.
    
    

    
    An optional list of cookie attributes can be specified, as per the example below.
    These attributes are inserted into the cookie as is, and are not interpreted by
    Apache. Ensure that your attributes are defined correctly as per the cookie specification.
    
    

    
    Cookie2 with attributes
    Session On
SessionCookieName2 session path=/private;domain=example.com;httponly;secure;version=1;
    

    



    

    top
    

    SessionCookieRemove Directive
    

    

    Description:Control for whether session cookies should be removed from incoming HTTP headers
    

    Syntax:SessionCookieRemove On|Off
    

    Default:SessionCookieRemove Off
    

    Context:server config, virtual host, directory, .htaccess
    

    Status:Extension
    

    Module:mod_session_cookie
    

    
    
    The SessionCookieRemove flag controls whether the cookies
    containing the session will be removed from the headers during request processing.
    

    
    In a reverse proxy situation where the Apache server acts as a server frontend for
    a backend origin server, revealing the contents of the session cookie to the backend
    could be a potential privacy violation. When set to on, the session cookie will be
    removed from the incoming HTTP headers.

    Module Apache mod_socache_redis
    

    

    Langues Disponibles:  en  |

    Description:Fournisseur de cache d'objets partagé basé sur Redis.
    

    Statut:Extension
    

    Identificateur de Module:socache_redis_module
    

    Fichier Source:mod_socache_redis.c
    

    Compatibilité:Disponible à partir de la version 2.4.39 du serveur HTTP Apache
    

    Sommaire
    

    
    mod_socache_redis implémente un fournisseur de cache
    d'objets partagé qui permet la création et l'accès à un cache hébergé par le
    système de mise en cache d'objets en mémoire partagée à hautes performances
    Redis.
    
    

    
    La méthode "create" de ce fournisseur de cache d'objets partagé nécessite
    une liste en mémoire de spécifications hôte/port séparées par des virgules.
    Si vous utilisez ce fournisseur dans une directive de configuration d'un autre
    module comme SSLSessionCache,
    spécifiez la liste des serveurs sous la forme du paramètre optionnel "arg" :
    

    
    SSLSessionCache redis:redis.example.com:12345,redis2.example.com:12345
    


    
    Vous trouverez une description détaillée des autres fournisseurs de cache
    d'objets partagé ici.

    Compatibilité:Disponible à partir de la version 2.4.39 du serveur HTTP Apache.
    

    
    
    Cette directive permet de définir la durée pendant laquelle les
    connexions inactives avec le(s) serveur(s) Redis seront conservées
    (plateformes threadées seulement).
    
    
    
    Les valeurs valides pour RedisConnPoolTTL sont des
    durées limitées à 1 heure . 0 signifie aucune limite.
    

    
    Par défaut, l'unité de ces valeurs est la secondes, mais on peut
    spécifier via un suffixe des valeurs en millisecondes (ms), en secondes (s),
    en minutes (min) ou en heures (h).
    
    

    
    # Définit une durée de vie de 10 minutes
RedisConnPoolTTL 10min
# Définit une durée de vie de 60 secondes
RedisConnPoolTTL 60

    Description:Permet d'atteindre différentes parties du système de
fichiers depuis l'arborescence des documents du site web, ainsi que la
redirection d'URL
    

    Statut:Base
    

    Identificateur de Module:alias_module
    

    Fichier Source:mod_alias.c
    

    Sommaire
    

    
    Les directives fournies par ce module permettent de manipuler et
    de contrôler les URLs à l'arrivée des requêtes sur le serveur. Les
    directives Alias et
    ScriptAlias permettent de
    faire correspondre des URLs avec des chemins du système de fichiers.
    Ceci permet de servir des contenus qui ne sont pas situés dans
    l'arborescence de DocumentRoot comme s'ils y étaient
    réellement. La directive ScriptAlias a pour effet
    supplémentaire de marquer le répertoire cible comme conteneur de
    scripts CGI.
    

    
    Les directives Redirect
    indiquent aux clients qu'ils doivent effectuer une nouvelle requête
    avec une URL différente. Elles sont souvent utilisées lorsqu'une
    ressource a été déplacée.
    

    
    Lorsque les directives Alias, ScriptAlias ou Redirect sont définies au sein d'une
    section <Location>
    ou <LocationMatch>, vous pouvez utiliser la syntaxe des expressions pour manipuler l'URL
    ou le chemin de destination.
	
    

    
    mod_alias est conçu pour traiter des tâches
    simples de manipulation d'URL. Pour des tâches plus complexes comme
    la manipulation des chaînes d'arguments des requêtes, utilisez
    plutôt les outils fournis par le module mod_rewrite
    


    


    top
    

    

    Chronologie du traitement
    

    
    Les alias et redirections apparaissant dans différents contextes
    sont traités comme les autres directives en respectant les règles de fusion standards. Par
    contre, ils sont traités selon une chronologie particulière
    lorsqu'ils apparaissent dans le même contexte (par exemple, dans la
    même section <VirtualHost>).
    

    
    Premièrement, toutes les redirections sont traitées avant les
    alias, et ainsi, une requête qui correspond à une directive
    Redirect ou RedirectMatch ne se verra jamais
    appliquer d'alias. Deuxièmement, les alias et redirections sont
    traités selon l'ordre dans lequel ils apparaissent dans le fichier
    de configuration, seule la première correspondance étant prise en
    compte.
    

    
    Ainsi, lorsqu'une ou plusieurs de ces directives s'appliquent au
    même sous-répertoire, vous devez classer les chemins du plus précis
    au moins précis afin que toutes les directives puissent
    éventuellement s'appliquer, comme dans l'exemple suivant :
    

    
    Alias "/foo/bar" "/baz"
Alias "/foo" "/gaq"
    


    
    Si l'ordre des directives était inversé, la directive Alias ayant pour argument
    /foo serait toujours appliquée avant la directive
    Alias ayant pour argument
    /foo/bar, et cette dernière serait toujours
    ignorée.
    

    
    La définition de directives Alias, ScriptAlias ou Redirect au sein de sections
    <Location> ou
    <LocationMatch>
    l'emporte sur d'autres définitions éventuelles de ces mêmes
    directives au niveau de la configuration générale du serveur.
    


    

    top
    

    Directive Alias
    

    

    Description:Met en correspondance des URLs avec des chemins du système
de fichiers
    

    Syntaxe:Alias [chemin URL]
chemin fichier|chemin répertoire
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_alias
    

    

    
    La directive Alias permet de stocker des
    documents (destinés à être servis) dans des zones du système de
    fichiers situées en dehors de l'arborescence du site web DocumentRoot. Les URLs dont le chemin
    (décodé avec caractères %) commence par chemin URL seront
    mises en correspondance avec des fichiers locaux dont le chemin
    commence par chemin répertoire. Le chemin URL
    est sensible à la casse, même sur les systèmes de fichiers
    insensibles à la casse.
    

    
    Alias "/image" "/ftp/pub/image"
    


    
    Une requête pour http://example.com/image/foo.gif fera
    renvoyer par le serveur le fichier
    /ftp/pub/image/foo.gif. Seuls les éléments de chemin
    complets sont testés ; ainsi l'alias précédent ne conviendra pas
    pour une requête du style http://example.com/imagefoo.gif.
    Pour des mises en correspondance plus complexes faisant intervenir
    les expressions rationnelles, veuillez vous reporter à la directive
    AliasMatch.
    

    
    Notez que si vous ajoutez un slash de fin au chemin
    URL, vous devrez aussi ajouter un slash de fin au chemin de la
    requête. Autrement dit, si vous définissez
    

    
    Alias "/icons/" "/usr/local/apache/icons/"
    


    
    l'alias précédent ne s'appliquera pas à l'URL
    /icons à cause de l'absence du slash final. Ainsi, si
    le slash final est absent du chemin de l'URL, il doit
    aussi l'être du chemin du fichier.
    

    
    Notez qu'il pourra s'avérer nécessaire de définir des sections
    <Directory>
    supplémentaires qui couvriront la  destination des alias.
    Le traitement des alias intervenant avant le traitement des sections
    <Directory>,
    seules les cibles des alias sont affectées (Notez cependant
    que les sections <Location> sont traitées avant les alias, et
    s'appliqueront donc).
    

    
    En particulier, si vous créez un alias ayant pour cible un
    répertoire situé en dehors de l'arborescence de votre site web
    DocumentRoot, vous devrez
    probablement permettre explicitement l'accès à ce répertoire.
    

    
    Alias "/image" "/ftp/pub/image"
<Directory "/ftp/pub/image">
    Require all granted
</Directory>
    


    
    Le nombre de slashes dans le paramètre chemin URL doit
    correspondre au nombre de slashes dans le chemin URL de la requête.
    

    
    Si la directive Alias est définie au sein
    d'une section <Location> ou <LocationMatch>, chemin URL est
    omis et chemin fichier est interprété en utilisant la syntaxe des expressions.
    
    Cette syntaxe est disponible à partir de la version 2.4.19 du
    serveur HTTP Apache.
    

    
    <Location "/image">
    Alias "/ftp/pub/image"
</Location>
<LocationMatch "/error/(?<NUMBER>[0-9]+)">
    Alias "/usr/local/apache/errors/%{env:MATCH_NUMBER}.html"
</LocationMatch>
    




    

    top
    

    Directive AliasMatch
    

    

    Description:Met en correspondance des URLs avec le système de fichiers
en faisant intervenir les expressions rationnelles
    

    Syntaxe:AliasMatch regex
chemin fichier|chemin répertoire
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_alias
    

    
    
    Cette directive est identique à la directive Alias, mais fait appel aux expressions rationnelles, à la place d'une
    simple mise en correspondance de préfixe. L'expression rationnelle
    fournie est mise en correspondance avec le chemin URL, et si elle
    correspond, le serveur va substituer toute partie de chemin
    correspondant à l'expression entre parenthèses dans la chaîne
    fournie et l'utiliser comme nom de fichier.
    Par exemple, pour activer le répertoire /icons, on peut
    utiliser :
    

    
    AliasMatch "^/icons(.*)" "/usr/local/apache/icons$1$2"
    


    
    Toute la puissance des expressions
    rationnelles peut être mise à contribution. Par exemple,
    il est possible de construire un alias avec un modèle de chemin URL
    insensible à la casse :
    

    
    AliasMatch "(?i)^/image(.*)" "/ftp/pub/image$1"
    


    
    Il existe une différence subtile entre Alias et AliasMatch : Alias copie automatiquement toute
    portion supplémentaire de l'URI située après la partie du modèle qui
    correspond, à la fin du chemin du fichier de la partie droite, alors
    que AliasMatch ne le fait
    pas. Cela signifie qu'il sera préférable dans la plupart des cas de
    comparer l'expression rationnelle du modèle à la totalité de l'URI
    de la requête, et d'utiliser les substitutions dans la partie
    droite.
    

    
    En d'autres termes, le remplacement d'Alias par AliasMatch ne produira pas le même
    résultat. Au minimum, vous devez ajouter ^ au début de
    l'expression rationnelle, (.*)$ à sa fin et
    $1 à la fin de la chaîne de remplacement.
    

    
    Par exemple, supposons que nous voulions reformuler cet alias
    avec AliasMatch :
    

    
    Alias "/image/" "/ftp/pub/image/"
    


    
    Le simple remplacement d'Alias par AliasMatch ne produira pas le
    même résultat. Ainsi, ce qui suit va rediriger toutes les requêtes
    qui contiennent /image/ vers /ftp/pub/image/ :
    

    
    AliasMatch "/image/" "/ftp/pub/image/"
    


    
    Voici la directive AliasMatch qui produira le même résultat que
    la directive Alias ci-dessus :
    

    
    AliasMatch "^/image/(.*)$" "/ftp/pub/image/$1"
    


    
    Bien entendu, il n'y a aucune raison d'utiliser AliasMatch dans le cas où Alias suffit. AliasMatch vous permet d'effectuer
    des choses beaucoup plus sophistiquées. Par exemple, vous pouvez
    servir différentes sortes de fichiers à partir de répertoires
    différents :
    

    
          AliasMatch "^/image/(.*)\.jpg$" "/fichiers/jpg.images/$1.jpg"
      AliasMatch "^/image/(.*)\.gif$" "/fichiers/gif.images/$1.gif"
    


    
    Les éventuels slashes de tête multiples seront supprimés par le
    serveur avant que les directives de ce module n'effectuent des
    comparaisons avec le chemin URL de la requête.

    Directive Redirect
    

    

    Description:Envoie une redirection externe demandant au client
d'effectuer une autre requête avec une URL différente
    

    Syntaxe:Redirect [état] [URL-path]
URL
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Base
    

    Module:mod_alias
    

    
    
    La directive Redirect permet de faire correspondre
    une ancienne URL à une nouvelle en demandant au client d'aller chercher la
    ressource à une autre localisation.
    

    
    L'ancien URL-path est un chemin sensible à la casse
    (décodé à l'aide de caractères %) commençant par un slash. Les
    chemins relatifs ne sont pas autorisés.
    

    
    La nouvelle URL
    peut être une URL absolue commençant par un protocole et un nom
    d'hôte, mais on peut aussi utiliser un chemin URL commençant par un
    slash, auquel cas le protocole et le nom d'hôte du serveur local
    seront ajoutés.
    

    
    Ensuite, toute requête commençant par URL-path va
    renvoyer une redirection au client vers l'URL cible. Tout
    élément de chemin supplémentaire situé en aval du URL-path sera
    ajouté à l'URL cible.
    

    
    # Redirige vers une URL sur un serveur différent
Redirect "/service" "http://foo2.example.com/service"

# Redirige vers une URL sur le même serveur
Redirect "/one" "/two"
    


    
    Si le client effectue une requête pour l'URL
    http://example.com/service/foo.txt, il lui sera demandé
    d'en effectuer une autre pour l'URL
    http://foo2.example.com/service/foo.txt. Ceci concerne
    les requêtes avec paramètres GET, comme
    http://example.com/service/foo.pl?q=23&a=42, qui
    seront redirigées vers
    http://foo2.example.com/service/foo.pl?q=23&a=42.
    Notez que les POSTs seront ignorés.
    
    Seuls les
    éléments de chemin complets sont testés, si bien que l'exemple
    précédent ne s'appliquera pas à l'URL
    http://example.com/servicefoo.txt. Pour des mises en
    correspondance plus complexes utilisant la syntaxe des expressions, ne spécifiez pas
    d'argument URL-path comme décrit ci-dessous. En outre,
    pour une mise en correspondance en utilisant les expressions
    rationnelles, veuillez vous reporter à la directive RedirectMatch.
    


    
    Note
    
    
    Les directives Redirect ont priorité sur les
    directives Alias et ScriptAlias, quel que soit leur ordre
    d'apparition dans le fichier de configuration. Les directives
    Redirect définies au sein d'une section Location
    l'emportent sur les directives Redirect et Alias comportant un argument
    URL-path.
    

    
    Si aucun argument état n'est spécifié, la
    redirection sera temporaire (code HTTP 302). Le client est alors
    informé que la ressource a été temporairement déplacée. On peut
    utiliser l'argument état pour renvoyer d'autres codes HTTP :
    

    
    
      
    permanent
    

      
    Renvoie un code de redirection permanente (301), indiquant
      que la ressource a été définitivement déplacée.
    

      
    temp
    

      
    Renvoie un code de redirection temporaire (302). C'est le
      comportement par défaut.
    

      
    seeother
    

      
    Renvoie un code "See Other" (303) indiquant que la ressource
      a été remplacée par une autre.
    

      
    gone
    

      
    Renvoie un code "Gone" (410) indiquant que la ressource a
      été définitivement supprimée. Lorsque
      ce code est utilisé, on ne
      doit pas utiliser l'argument URL.
    
    
    

    
    On peut renvoyer d'autres codes en spécifiant le code
    numérique comme valeur de l'argument of état.
    Si le code est compris entre 300 et 399, l'argument
    URL doit être présent. Si le code
    n'est pas compris entre 300 et 399, l'argument
    URL ne doit pas apparaître. Le code doit être un code
    HTTP valide, connu du serveur HTTP Apache (voir la
    fonction send_error_response dans
    http_protocol.c).
    

    
    Redirect permanent "/one" "http://example.com/two"
Redirect 303 "/three" "http://example.com/other"
    


    
    Si une directive Redirect est définie au
    sein d'une section <Location> ou <LocationMatch> et si l'argument URL-path est omis, l'argument URL sera interprété en
    utilisant la syntaxe des expressions.
    
    Cette syntaxe est disponible à partir de la version 2.4.19 du
    serveur HTTP Apache.
    

    
    <Location "/one">
    Redirect permanent "http://example.com/two"
</Location>
<Location "/three">
    Redirect 303 "http://example.com/other"
</Location>
<LocationMatch "/error/(?<NUMBER>[0-9]+)">
    Redirect permanent "http://example.com/errors/%{env:MATCH_NUMBER}.html"
</LocationMatch>

    Directive RedirectMatch
    

    

    Description:Envoie une redirection externe faisant appel aux
expressions rationnelles pour la mise en correspondance de l'URL
courante
    

    Syntaxe:RedirectMatch [état] regex
URL
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Base
    

    Module:mod_alias
    

    
    
    Cette directive est identique à la directive Redirect, mais fait appel aux
    expressions rationnelles, à la
    place d'une simple mise en correspondance de préfixe. L'expression
    rationnelle fournie est mise en correspondance avec le chemin URL,
    et si elle correspond, le serveur va substituer toute partie de
    chemin correspondante entre parenthèses dans la chaîne spécifiée et
    l'utiliser comme nom de fichier. Par exemple, pour rediriger tous
    les fichiers GIF vers les fichiers JPEG de même nom sur un autre
    serveur, on peut utiliser :
    

    
    RedirectMatch "(.*)\.gif$" "http://autre.example.com$1.jpg"
    


    
    Les remarques à propos de la différence entre Alias et AliasMatch s'appliquent aussi à la
    différence entre les directives Redirect et RedirectMatch. Voir la directive
    AliasMatch pour plus de
    détails.

    Directive RedirectPermanent
    

    

    Description:Envoie une redirection externe permanente demandant au
client d'effectuer une nouvelle requête avec une URL
différente
    

    Syntaxe:RedirectPermanent chemin URL URL
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:FileInfo
    

    Statut:Base
    

    Module:mod_alias

    Module:mod_alias
    

    
    
    Cette directive informe le client que la redirection n'est
    que temporaire (code 302). Son comportement est exactement le même
    que celui de Redirect temp.
    


    

    top
    

    Directive ScriptAlias
    

    

    Description:Fait correspondre une URL à une zone du système de fichiers
et désigne la cible comme script CGI
    

    Syntaxe:ScriptAlias [chemin URL]
chemin fichier|chemin répertoire
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_alias
    

    
    
    La directive ScriptAlias présente le même
    comportement que la directive Alias, mais désigne en plus le
    répertoire cible comme conteneur de scripts CGI qui seront traitées
    par le gestionnaire cgi-script du module mod_cgi.
    Les URLs dont le chemin URL sensible à la casse (décodé avec
    caractères %) commence par chemin URL seront mises en
    correspondance avec les scripts dont le chemin commence par le
    second argument, qui est un chemin complet dans le système de
    fichiers local.
    

    
    ScriptAlias "/cgi-bin/" "/web/cgi-bin/"
    


    
    Une requête pour http://example.com/cgi-bin/foo
    ferait exécuter par le serveur le script
    /web/cgi-bin/foo. Cette configuration est sensiblement
    équivalente à :
    
    
    Alias "/cgi-bin/" "/web/cgi-bin/"
<Location "/cgi-bin">
    SetHandler cgi-script
    Options +ExecCGI
</Location>
    


	
    Vous pouvez aussi utiliser ScriptAlias
	avec un script ou gestionnaire de votre cru. Par exemple :
    

	
    ScriptAlias "/cgi-bin/" "/web/cgi-handler.pl"
    


    
    Dans ce scénario, tous les fichiers faisant l'objet d'une requête
    dans /cgi-bin/ seront traités par le fichier que vous
    avez spécifié, ce qui vous permet d'utiliser votre propre
    gestionnaire. Vous pouvez l'utiliser comme enveloppe (wrapper) pour
    les scripts CGI afin d'ajouter du contenu, ou autre action "maison".
    

    
    Il est préférable d'éviter de placer les
    scripts CGI dans l'arborescence de DocumentRoot afin d'éviter de révéler
    accidentellement leur code source lors d'une modification de
    configuration. On y parvient aisément avec
    ScriptAlias en mettant en correspondance une
    URL et en désignant la cible comme scripts CGI par la même occasion.
    Si vous choisissez de placer vos scripts CGI dans un répertoire
    accessible depuis le web, n'utilisez pas
    ScriptAlias. Utilisez plutôt <Directory>, SetHandler, et Options comme dans l'exemple suivant :
    
    <Directory "/usr/local/apache2/htdocs/cgi-bin">
    SetHandler cgi-script
    Options ExecCGI
</Directory>
    

    Ceci est nécessaire car plusieurs chemins URL peuvent
    correspondre à la même zone du système de fichiers, court-circuitant
    ainsi la directive ScriptAlias et révélant le
    code source des scripts CGI s'ils ne sont pas protégés par une
    section Directory.
    

    
    Si la directive ScriptAlias est définie au
    sein d'une section <Location> ou <LocationMatch> et si l'argument chemin
    URL est omis, l'argument URL sera interprété en
    utilisant la syntaxe des expressions.
    
    Cette syntaxe est disponible à partir de la version 2.4.19 du
    serveur HTTP Apache.
    

    
    <Location "/cgi-bin">
    ScriptAlias "/web/cgi-bin/"
</Location>
<LocationMatch "/cgi-bin/errors/(?<NUMBER>[0-9]+)">
    ScriptAlias "/web/cgi-bin/errors/%{env:MATCH_NUMBER}.cgi"
</LocationMatch>

    standard /cgi-bin, on peut utiliser :
    

    
    ScriptAliasMatch "^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"
    


    
    Comme dans le cas d'AliasMatch, toute la puissance des expressions rationnelles peut être mise à
    contribution. Par exemple, il est possible de construire un alias
    avec une comparaison du modèle du chemin URL insensible à la casse :
    

    
    ScriptAliasMatch "(?i)^/cgi-bin(.*)" "/usr/local/apache/cgi-bin$1"

    Status を使用可能にする
    
    

    
    example.com ドメインからのブラウザのみに対して
    ステータスの報告を使用可能にするには
    以下のコードを httpd.conf 設定ファイルに追加します
    

    
    <Location /server-status>
    
    SetHandler server-status
    

    
    Order Deny,Allow
    
    Deny from all
    
    Allow from .example.com
    
    </Location>

    

    
    これで、サーバの統計情報をウェブブラウザを使って
    http://your.server.name/server-status をアクセスすることにより
    知ることができるようになります。

    自動更新
    

    
    
    ブラウザが「リフレッシュ」機能をサポートしていれば、ステータスページを
    自動的に更新するようにできます。N 秒毎に更新させるためには
    http://your.server.name/server-status?refresh=N
    というページをアクセスしてください。

    機械読み取り可能なステータスファイル
    

    
    
    http://your.server.name/server-status?auto を
    アクセスすることにより、ステータスファイルの機械読み取り可能なバージョンを
    得ることができます。これは自動的に実行されるときに便利です。
    Apache の /support ディレクトリにある
    Perl プログラム log_server_status を見てください。
    

    
    
      mod_status がサーバに組み込まれている
      場合、ハンドラの機能はディレクトリ毎のファイル
      (すなわち、.htaccess) も含むすべての
      設定ファイルで使用可能になることには注意をしておく必要があります。
      これは、サイトによってはセキュリティに関する望ましくない結果を
      もたらすことがあるかもしれません。

    SetEnvIf
    ディレクティブは、リクエストの属性に基づいて環境変数を定義します。
    最初の引数で指定できる attribute は以下の 4 つのどれかです:
    


      

    1. HTTP リクエストヘッダフィールド (詳しい情報は RFC 2616 を
    参照してください)。例えば、Host,
    User-Agent, Referer, 
    Accept-Language です。リクエストヘッダの集合を現すために
    正規表現を使うこともできます。
      2. 


    2. 以下のリクエストの一部分のどれか:

    
        
      
      • Remote_Host -
      リクエストを行なっているクライアントのホスト名 (もしあれば)
        • 

      
      • Remote_Addr -
      リクエストを行なっているクライアントの IP アドレス
        • 

      
      • Server_Addr - 
      リクエストを受け取ったサーバの IP アドレス
      (2.0.43 以降のみ)
        • 

      
      • Request_Method -
      使用されているメソッド名 (GET, POST
      など)
        • 

      
      • Request_Protocol -
      リクエストが行なわれたプロトコルの名前とバージョン
      (例えば、"HTTP/0.9", "HTTP/1.1" など。)
        • 

      
      • Request_URI -
      URL のスキームとホストの後の部分。
      追加の情報として、クエリーストリングにマッチさせる場合については
      RewriteCond
      ディレクティブを参照してください。
        • 
    
      

      3. 


    3. リクエストと関連付けられる環境変数のリスト。これにより
SetEnvIf ディレクティブが以前のマッチの結果を
使うことができるようになります。この方法のテストでは前の部分にある
SetEnvIf[NoCase] の結果のみを使用可能です。「前」とは、
より広い範囲に対して定義されている (サーバ全体のように) か、現在のディレクティブの
範囲でより前の部分で定義されているか、ということです。
環境変数である可能性は、リクエストの特性に対するマッチが存在せず、
attribute に正規表現が使われなかったときにのみ考慮されます。
      4. 


    4. 
 SSL クライアント証明書拡張への参照で、oid オブジェクト ID 
 で指定されるもの。
 SSL リクエストでない場合や oid が設定されていなかった場合は、
 変数はセットされません。oid が複数見つかった場合は
 それらの文字列はカンマ ',' 区切りで連結されます。
 oid は文字列型拡張への参照でなければなりません。

      5. 

    


    二つ目の引数 (regex) は 正規表現です。
これは POSIX.2 の egrep 形式の正規表現と似ています。regex が
attribute にマッチする場合は、残りの引数が評価されます。
    


    残りの引数は設定する変数の名前で、設定される値を指定することもできます。
これは、
    

    
      
      
    1. varname
      2. 

      
    2. !varname
      3. 

      
    3. varname=value
      4. 
    
    

    
    のどれかの形式になります。
    

    
    最初の形式では、値は "1" に設定されます。
    二つ目はもし値が定義されていればそれを取り除きます。
    三つ目は変数を value の与えられた値に設定します。
    2.0.51 以降では、value 内に $1..$9
    が存在すればそれを認識し、regex の対応する丸括弧で囲まれた部分で
    置換します。
    


    例:
    

   SetEnvIf Request_URI "\.gif$" object_is_image=gif
    
   SetEnvIf Request_URI "\.jpg$" object_is_image=jpg
    
   SetEnvIf Request_URI "\.xbm$" object_is_image=xbm
    
        :
    
   SetEnvIf Referer www\.mydomain\.example\.com intra_site_referral
    
        :
    
   SetEnvIf object_is_image xbm XBIT_PROCESSING=1
    
        :
    
   SetEnvIf OID("2.16.840.1.113730.1.13") "(.*)" NetscapeComment=$1
    
        :
    
   SetEnvIf ^TS*  ^[a-z].*  HAVE_TS
    

    

    
    初めの三つはリクエストが画像であるときに環境変数
    object_is_image を設定します。四つ目は
    参照元のページがウェブサイト www.mydomain.example.com にあるときに
    intra_site_referral を設定します。
    

    
    6番目の例では環境変数 NetscapeComment を定義して、
    その値が SSL クライアント証明書の対応するフィールドの文字列であるようにします。
    ただし SSL クライアント証明書の対応するフィールドに文字列が存在する
    ときにのみ、環境変数は設定されます。
    

    
    最後の例は、リクエストに "TS" で始まり、値が集合 [a-z] のどれかで
    始まるヘッダがあるときに HAVE_TS を設定します。

    これは HTTP リクエストヘッダにフィールド Host: が
    あり、その値が Apache.Org や apache.org、
    その他の大文字小文字の組み合わせであったときに site
    環境変数を "apache" に設定します。

    Description:Multi-Processing Module implementing a hybrid
    multi-threaded multi-process web server
    

    Status:MPM
    

    Module Identifier:mpm_worker_module
    

    Source File:worker.c
    

    Summary
    

    
    This Multi-Processing Module (MPM) implements a hybrid
    multi-process multi-threaded server. By using threads to serve
    requests, it is able to serve a large number of requests with
    fewer system resources than a process-based server. However, it
    retains much of the stability of a process-based server by
    keeping multiple processes available, each with many threads.
    

    
    The most important directives used to control this MPM are
    ThreadsPerChild, which
    controls the number of threads deployed by each child process and
    MaxRequestWorkers, which
    controls the maximum total number of threads that may be
    launched.
    

    


    top
    

    

    How it Works
    
    
    A single control process (the parent) is responsible for launching
    child processes. Each child process creates a fixed number of server
    threads as specified in the ThreadsPerChild directive, as well
    as a listener thread which listens for connections and passes them
    to a server thread for processing when they arrive.
    

    
    Apache HTTP Server always tries to maintain a pool of spare or
    idle server threads, which stand ready to serve incoming
    requests. In this way, clients do not need to wait for a new
    threads or processes to be created before their requests can be
    served. The number of processes that will initially launch is
    set by the StartServers
    directive. During operation, the server assesses the total number
    of idle threads in all processes, and forks or kills processes to
    keep this number within the boundaries specified by MinSpareThreads and MaxSpareThreads. Since this
    process is very self-regulating, it is rarely necessary to modify
    these directives from their default values. The maximum number of
    clients that may be served simultaneously (i.e., the maximum total
    number of threads in all processes) is determined by the
    MaxRequestWorkers directive.
    The maximum number of active child processes is determined by
    the MaxRequestWorkers
    directive divided by the 
    ThreadsPerChild directive.
    

    
    Two directives set hard limits on the number of active child
    processes and the number of server threads in a child process,
    and can only be changed by fully stopping the server and then
    starting it again.  ServerLimit
     is a hard limit on the number of active child
    processes, and must be greater than or equal to the
    MaxRequestWorkers
    directive divided by the 
    ThreadsPerChild directive.
    ThreadLimit is a hard
    limit of the number of server threads, and must be greater than
    or equal to the ThreadsPerChild directive.
    

    
    In addition to the set of active child processes, there may
    be additional child processes which are terminating, but where at
    least one server thread is still handling an existing client
    connection.  Up to MaxRequestWorkers terminating processes
    may be present, though the actual number can be expected to be
    much smaller.  This behavior can be avoided by disabling the
    termination of individual child processes, which is achieved using
    the following:
    

    

    
    A typical configuration of the process-thread controls in
    the worker MPM could look as follows:
    

    
    ServerLimit         16
StartServers         2
MaxRequestWorkers  150
MinSpareThreads     25
MaxSpareThreads     75
ThreadsPerChild     25
    


    
    While the parent process is usually started as root
    under Unix in order to bind to port 80, the child processes and threads
    are launched by the server as a less-privileged user. The User and Group directives are used to set
    the privileges of the Apache HTTP Server child processes. The child processes
    must be able to read all the content that will be served, but
    should have as few privileges beyond that as possible. In
    addition, unless suexec is used,
    these directives also set the privileges which will be inherited
    by CGI scripts.
    

    
    MaxConnectionsPerChild
    controls how frequently the server recycles processes by killing
    old ones and launching new ones.
    

    
    This MPM uses the mpm-accept mutex to serialize
    access to incoming connections when subject to the thundering herd
    problem (generally, when there are multiple listening sockets).
    The implementation aspects of this mutex can be configured with the
    Mutex directive.  The performance hints
    documentation has additional information about this mutex.

    Description:Permet à une application d'autorisation FastCGI de gérer
l'authentification et l'autorisation httpd.
    

    Statut:Extension
    

    Identificateur de Module:authnz_fcgi_module
    

    Fichier Source:mod_authnz_fcgi.c
    

    Compatibilité:Disponible à partir de la version 2.4.10 du serveur HTTP
Apache
    

    Sommaire
    

    
    Ce module permet aux applications d'autorisation FastCGI
    d'authentifier les utilisateurs et de contrôler leur accès aux
    ressources. Il supporte les systèmes d'autorisation FastCGI
    génériques qui participent en une seule phase à l'authentification
    et à l'autorisation, ainsi que les processus d'authentification et
    d'autorisation spécifiques à Apache httpd qui interviennent en une
    ou plusieurs phases.
    

    
    Les processus d'autorisation FastCGI peuvent authentifier un
    utilisateur via son identificateur et son mot de passe comme dans le
    processus d'authentification basique, ou via un mécanisme
    arbitraire.
    

    


    top
    

    

    Modes d'invocation
    

    
    Les modes d'invocation des processus d'autorisation FastCGI que
    ce module supporte se distinguent par deux caractéristiques : le
    type et le mécanisme d'authentification.
    

    
    Le Type est simplement authn pour
    l'authentification, authz pour l'autorisation et
    authnz l'authentification et l'autorisation.
    

    
    Le mécanisme d'authentification fait référence aux
    mécanismes d'authentification et aux phases de traitement de la
    configuration de Apache httpd, et peut être
    AuthBasicProvider, Require, ou
    check_user_id. Les deux premiers mécanismes
    correspondent aux directives utilisées pour participer aux phases de
    traitement appropriées.
    

    
    Description de chaque mode:
    

    
    
      
    Type authn, mechanism
      AuthBasicProvider
    

      
    Dans ce mode, la variable FCGI_ROLE est définie à
      AUTHORIZER, et la variable
      FCGI_APACHE_ROLE à AUTHENTICATOR.
      L'application doit être spécifiée en tant que fournisseur de type
      authn via la directive AuthnzFcgiDefineProvider, et
      activée via la directive AuthBasicProvider. Lorsqu'elle
      est invoquée, l'application est censée authentifier le client à
      l'aide de l'identifiant et du mot de passe de l'utilisateur.
      Exemple d'application :


    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHENTICATOR";
    die if $ENV{'FCGI_ROLE'}        ne "AUTHORIZER";
    die if !$ENV{'REMOTE_PASSWD'};
    die if !$ENV{'REMOTE_USER'};

    print STDERR "This text is written to the web server error log.\n";

    if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &&
        $ENV{'REMOTE_PASSWD'} eq "bar" ) {
        print "Status: 200\n";
        print "Variable-AUTHN_1: authn_01\n";
        print "Variable-AUTHN_2: authn_02\n";
        print "\n";
    }
    else {
        print "Status: 401\n\n";
    }
}
    


      Exemple de configuration httpd :

    AuthnzFcgiDefineProvider authn FooAuthn fcgi://localhost:10102/
<Location "/protected/">
  AuthType Basic
  AuthName "Restricted"
  AuthBasicProvider FooAuthn
  Require ...
</Location>
    

      
    

      
    Type authz, mechanism
      Require
    
      
    Dans ce mode, la variable FCGI_ROLE est définie à
      AUTHORIZER et FCGI_APACHE_ROLE à
      AUTHORIZER. L'application doit être spécifiée en tant
      que fournisseur de type authz via la directive AuthnzFcgiDefineProvider.
      Lorsqu'elle est invoquée, l'application est censée contrôler les
      accès du client à l'aide de l'identifiant utilisateur et d'autres
      données contenues dans la requête. Exemple d'application :

    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHORIZER";
    die if $ENV{'FCGI_ROLE'}        ne "AUTHORIZER";
    die if $ENV{'REMOTE_PASSWD'};

    print STDERR "This text is written to the web server error log.\n";

    if ($ENV{'REMOTE_USER'} eq "foo1") {
        print "Status: 200\n";
        print "Variable-AUTHZ_1: authz_01\n";
        print "Variable-AUTHZ_2: authz_02\n";
        print "\n";
    }
    else {
        print "Status: 403\n\n";
    }
}
    


      Exemple de configuration httpd :

    AuthnzFcgiDefineProvider authz FooAuthz fcgi://localhost:10103/
<Location "/protected/">
  AuthType ...
  AuthName ...
  AuthBasicProvider ...
  Require FooAuthz
</Location>
    

      
    

      
    Type authnz, mechanism
      AuthBasicProvider + Require
    

      
    Dans ce mode qui supporte le protocole d'autorisation web
      server-agnostic FastCGI, la variable FCGI_ROLE est
      définie à AUTHORIZER et FCGI_APACHE_ROLE
      n'est pas définie. L'application doit être spécifiée en tant que
      fournisseur de type authnz via la directive AuthnzFcgiDefineProvider.
      L'application est censée assurer l'authentification et
      l'autorisation au cours d'une même invocation à l'aide de
      l'identifiant et du mot de passe de l'utilisateur et d'autres
      données contenues dans la requête. L'invocation de l'application
      intervient au cours de la phase d'authentification de l'API Apache
      httpd. Si l'application renvoie le code 200, et si le même
      fournisseur est invoqué au cours de la phase d'autorisation (via
      une directive Require), mod_authnz_fcgi
      renverra un code de type success pour la phase d'autorisation sans
      invoquer l'application. Exemple d'application :

    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'};
    die if $ENV{'FCGI_ROLE'} ne "AUTHORIZER";
    die if !$ENV{'REMOTE_PASSWD'};
    die if !$ENV{'REMOTE_USER'};

    print STDERR "This text is written to the web server error log.\n";

    if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &&
        $ENV{'REMOTE_PASSWD'} eq "bar" &&
        $ENV{'REQUEST_URI'} =~ m%/bar/.*%) {
        print "Status: 200\n";
        print "Variable-AUTHNZ_1: authnz_01\n";
        print "Variable-AUTHNZ_2: authnz_02\n";
        print "\n";
    }
    else {
        print "Status: 401\n\n";
    }
}
    


      Exemple de configuration httpd :

    AuthnzFcgiDefineProvider authnz FooAuthnz fcgi://localhost:10103/

    Type authn, mechanism
      check_user_id
    

      
    Dans ce mode, la variable FCGI_ROLE est définie à
      AUTHORIZER et FCGI_APACHE_ROLE à
      AUTHENTICATOR. L'application doit être spécifiée en
      tant que fournisseur de type authn via une directive
      AuthnzFcgiDefineProvider. La
      directive AuthnzFcgiCheckAuthnProvider
      permet de l'invoquer. Exemple d'application :

    #!/usr/bin/perl
use FCGI;
my $request = FCGI::Request();
while ($request->Accept() >= 0) {
    die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHENTICATOR";
    die if $ENV{'FCGI_ROLE'} ne "AUTHORIZER";

    # This authorizer assumes that the RequireBasicAuth option of 
    # AuthnzFcgiCheckAuthnProvider is On:
    die if !$ENV{'REMOTE_PASSWD'};
    die if !$ENV{'REMOTE_USER'};

    print STDERR "This text is written to the web server error log.\n";

    if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &&
        $ENV{'REMOTE_PASSWD'} eq "bar" ) {
        print "Status: 200\n";
        print "Variable-AUTHNZ_1: authnz_01\n";
        print "Variable-AUTHNZ_2: authnz_02\n";
        print "\n";
    }
    else {
        print "Status: 401\n\n";
        # If a response body is written here, it will be returned to
        # the client.
    }
}
    


      Exemple de configuration httpd :

    AuthnzFcgiDefineProvider authn FooAuthn fcgi://localhost:10103/
<Location "/protected/">
  AuthType ...
  AuthName ...
  AuthnzFcgiCheckAuthnProvider FooAuthn \
                               Authoritative On \
                               RequireBasicAuth Off \
                               UserExpr "%{reqenv:REMOTE_USER}"
  Require ...
</Location>
    

      
    

    
    
    

    top
    

    

    Exemples supplémentaires
    

  
      
    
    1. Si votre application supporte séparément les rôles
    d'authentification et d'autorisation (AUTHENTICATOR et
    AUTHORIZER), vous pouvez définir des fournisseurs
    séparés comme suit, même s'ils correspondent à la même application :


      AuthnzFcgiDefineProvider authn  FooAuthn  fcgi://localhost:10102/
AuthnzFcgiDefineProvider authz  FooAuthz  fcgi://localhost:10102/
      


    Spécifie le fournisseur authn via la directive 
    AuthBasicProvider
    et le fournisseur authz via la directive
    Require:


      AuthType Basic
AuthName "Restricted"
AuthBasicProvider FooAuthn
Require FooAuthz
      

    
      2. 

    
    2. Si votre application supporte le rôle générique
    AUTHORIZER (authentification et autorisation en une
    seule invocation), vous pouvez définir un fournisseur unique comme
    suit :


      AuthnzFcgiDefineProvider authnz FooAuthnz fcgi://localhost:10103/
      


    Spécifie le fournisseur authnz via les directives
    AuthBasicProvider et
    Require :


      AuthType Basic
AuthName "Restricted"
AuthBasicProvider FooAuthnz
Require FooAuthnz
      

    
      3. 

    

    top
    

    

    Limitations
    

    
    Les fonctionnalités suivantes ne sont pas encore implémentées :
    

    
    
      
    Vérificateur d'accès d'Apache httpd
    
      
    La phase access check de l'API Apache httpd est
      distincte des phases d'authentification et d'autorisation.
      Certaines autres implémentations de FastCGI supportent cette phase
      et lorsque c'est le cas, la variable FCGI_APACHE_ROLE
      est définie à ACCESS_CHECKER.
    

      
    Redirections (pipes) ou sockets locaux (Unix)
    
      
    Seuls les sockets TCP sont actuellement supportés.
    

      
    Support de mod_authn_socache
    
      
    Le support de l'interaction avec mod_authn_socache pour les
      applications qui interviennent dans le processus
      d'authentification d'Apache httpd serait souhaitable.
    

      
    Support de l'authentification de type digest à l'aide de AuthDigestProvider
    
      
    Cette limitation ne sera probablement jamais franchie car il
      n'existe aucun flux de données d'autorisation capable de lire dans
      un condensé de type hash.
    

      
    Gestion des processus applicatifs
    
      
    Cette fonctionnalité restera probablement hors de portée de ce
      module. Il faudra donc gérer les processus applicatifs d'une autre
      manière ; par exemple, fcgistarter permet de
      les démarrer.
    

      
    AP_AUTH_INTERNAL_PER_URI
    
      
    Tous les fournisseurs sont actuellement enregistrés en tant
      que AP_AUTH_INTERNAL_PER_CONF, ce qui signifie que les
      vérifications ne sont pas effectuées pour les
      sous-requêtes internes avec la même configuration de contrôle
      d'accès que la requête initiale.
    

      
    Conversion du jeu de caractères des données de protocole
    
      
    Si mod_authnz_fcgi s'exécute dans un environnement de
      compilation EBCDIC, toutes les données de protocole FastCGI sont
      écrites en EBCDIC et doivent être disponibles en EBCDIC.
    

      
    Plusieurs requêtes pour une connexion
    
      
    Actuellement, la connexion au fournisseur d'autorisation
      FastCGI est fermée après chaque phase de traitement. Par exemple,
      si le fournisseur d'autorisation gère séparément les phases
      authn et authz, deux connexions seront
      nécessaires.
    

      
    Redirection de certains URIs
    
      
    Les URIs en provenance des clients ne peuvent pas être
      redirigés selon une table de redirection, comme avec la directive
      ProxyPass utilisée avec les répondeurs
      FastCGI.
    

    
    


    top
    

    

    Journalisation
    

    
      
        
    1. Les erreurs de traitement sont journalisées à un niveau
	error ou supérieur.
      2. 
        
    2. Les messages envoyés par l'application sont journalisés au
	niveau warn.
      3. 
        
    3. Les messages de deboguage à caractère général sont
	journalisés au niveau debug.
      4. 
        
    4. Les variables d'environnement transmises à l'application
	sont journalisées au niveau trace2. La valeur de la
	variable REMOTE_PASSWD sera occultée, mais
	toute autre donnée sensible sera visible dans le
	journal.
      5. 
        
    5. Toutes les entrées/sorties entre le module et l'application
	FastCGI, y compris les variables d'environnement, seront
	journalisées au format imprimable et hexadécimal au niveau
	trace5. Toutes les données sensibles seront
	visibles dans le journal.
      6. 
    
    

    
    La directive LogLevel permet
    de configurer un niveau de journalisation spécifique à
    mod_authnz_fcgi. Par exemple :
    


    LogLevel info authnz_fcgi:trace8

    Directive AuthnzFcgiCheckAuthnProvider
    

    

    Description:Permet à une application FastCGI de gérer l'accroche
d'authentification check_authn.
    

    Syntaxe:AuthnzFcgiCheckAuthnProvider provider-name|None
option ...
    

    Défaut:none
    

    Contexte:répertoire
    

    Statut:Extension
    

    Module:mod_authnz_fcgi
    

    
    
    Cette directive permet de confier à une application FastCGI la
    gestion d'une phase spécifique du processus d'authentification ou
    d'autorisation.
    

    
    Certaines fonctionnalités des fournisseurs d'autorisation FastCGI
    nécessitent cette directive en lieu et place de
    AuthBasicProvider pour pouvoir être activées :
    

    
      
      
    • L'authentification de type autre que basique ; en général,
      détermination de l'identifiant utilisateur et renvoi de sa valeur
      depuis le fournisseur d'autorisation ; voir l'option
      UserExpr ci-dessous
      • 
      
    • Sélection d'un code de réponse personnalisé ; en cas de
      code de réponse autre que 200 en provenance du fournisseur
      d'autorisation, c'est ce code qui sera utilisé comme code d'état
      de la réponse
      • 
      
    • Définition du corps d'une réponse autre que 200 ; si le
      fournisseur d'autorisation renvoie un corps de réponse avec un
      code autre que 200, c'est ce corps de réponse qui sera renvoyé au
      client ; la longueur du texte est limitée à 8192 octets
      • 
    
    

    
    
      
    provider-name
    
      
    C'est le nom du fournisseur défini au préalable via la
      directive AuthnzFcgiDefineProvider.
    

      
    None
    
      
    Spécifiez None pour désactiver un fournisseur
      activé avec cette même directive dans une autre portée, par
      exemple dans un répertoire parent.
    

      
    option
    
      
    Les options suivantes sont supportées :
      
      
    
         
    Authoritative On|Off (par défaut On)
    
         
    Cette option permet de définir si l'appel à d'autres
	 modules est autorisé lorsqu'un fournisseur d'autorisation FastCGI a
	 été configuré et si la requête échoue.
    

         
    DefaultUser id utilisateur
    
         
    Lorsque le fournisseur d'autorisation donne son accord, et
	 si UserExpr est défini et correspond à une chaîne
	 vide, (par exemple, si le fournisseur d'autorisation ne renvoie
	 aucune variable), c'est cette valeur qui sera utilisée comme id
	 utilisateur par défaut. Cela se produit souvent lorsqu'on se trouve dans
	 un contexte d'invité, ou d'utilisateur non authentifié ;
	 les utilisateurs et invités se voient alors attribué un id
	 utilisateur spécifique qui permettra de se connecter et
	 d'accéder à certaines ressources.
    

         
    RequireBasicAuth On|Off (par défaut Off)
    
         
    Cette option permet de définir si l'authentification
	 basique est requise avant de transmettre la requête au
	 fournisseur d'autorisation. Dans l'affirmative, le fournisseur
	 d'autorisation ne sera invoqué qu'en présence d'un id
	 utilisateur et d'un mot de passe ; si ces deux éléments ne sont
	 pas présents, un code d'erreur 401 sera renvoyé
    

         
    UserExpr expr (pas de valeur par défaut)
    
         
    Lorsque le client ne fournit pas l'authentification basique
	 et si le fournisseur d'autorisation détermine l'id utilisateur,
	 cette expression, évaluée après l'appel au fournisseur
	 d'autorisation, permet de déterminer l'id utilisateur. Cette
	 expression se conforme à la syntaxe
	 ap_expr et doit correspondre à une chaîne de caractères.
	 Une utilisation courante consiste à référencer la définition
	 d'une Variable-XXX renvoyée par le
	 fournisseur d'autorisation via une option du style
	 UserExpr "%{reqenv:XXX}". Si cette option
	 est spécifiée, et si l'id utilisateur ne peut pas être définie
	 via l'expression après une authentification réussie, la requête
	 sera rejetée avec un code d'erreur 500.

    Directive AuthnzFcgiDefineProvider
    

    

    Description:Définit une application FastCGI en tant que fournisseur
d'authentification et/ou autorisation
    

    Syntaxe:AuthnzFcgiDefineProvider type provider-name
backend-address
    

    Défaut:none
    

    Contexte:configuration globale
    

    Statut:Extension
    

    Module:mod_authnz_fcgi
    

    
    
    Cette directive permet de définir une application FastCGI en tant
    que fournisseur pour une phase particulière d'authentification ou
    d'autorisation.
    

    
    
      
    type
    
      
    Les valeurs de ce paramètre sont authn pour
      l'authentification, authz pour l'autorisation, ou
      authnz pour un fournisseur d'autorisation générique
      FastCGI qui effectue les deux vérifications.
    

      
    provider-name
    
      
    Ce paramètre permet d'associer un nom au fournisseur ; ce nom
      pourra être utilisé dans des directives comme AuthBasicProvider et
      Require.
    

      
    backend-address
    
      
    Ce paramètre permet de spécifier l'adresse de l'application
      sous la forme fcgi://hostname:port/. Le ou les processus
      de l'application doivent être gérés indépendamment comme avec
      fcgistarter.

    Identificateur de Module:dav_fs_module
    

    Fichier Source:mod_dav_fs.c
    

    Sommaire
    

    
    L'activation de ce module nécessite l'utilisation de
    mod_dav. C'est un module de support pour mod_dav et à ce titre, il permet l'accès à des ressources
    situées dans le système de fichiers du serveur. Le nom formel de ce
    fournisseur est filesystem. Les fournisseurs supports
    de mod_dav sont invoqués via la directive
    Dav :
    

    
    Exemple
    Dav filesystem
    

    

    
    Comme filesystem est le fournisseur par défaut de
    mod_dav, vous pouvez vous contenter d'utiliser la
    valeur On comme argument de Dav.

    Syntaxe:DavLockDB chemin fichier
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_dav_fs
    

    
    
    La directive DavLockDB permet de spécifier
    le chemin complet de la base de données des verrous, sans extension.
    Si le chemin n'est pas absolu, il sera considéré comme relatif au
    répertoire défini par la directive ServerRoot. L'implémentation de
    mod_dav_fs utilise une base de données SDBM pour
    surveiller les verrous utilisateurs.
    

    

    
    Exemple
    DavLockDB "var/DavLock"
    

    

    
    Les utilisateur et groupe sous lesquels Apache s'exécute et qui
    sont respectivement définis par les directives User et Group doivent pouvoir écrire dans le
    répertoire qui contient le fichier de la base de données des
    verrous. Pour des raisons de sécurité, il est recommandé de créer un
    répertoire dédié à la base de données des verrous, plutôt que de
    modifier les permissions d'un répertoire existant. Dans l'exemple
    ci-dessus, Apache va créer des fichiers dans le répertoire
    var/, lui-même sous-répertoire du répertoire défini par
    la directive ServerRoot, avec le nom de base
    DavLock suivi d'une extension choisie par le
    serveur.

    Description:Journalisation des requêtes envoyées au
serveur
    

    Statut:Base
    

    Identificateur de Module:log_config_module
    

    Fichier Source:mod_log_config.c
    

    Sommaire
    

    
    Ce module apporte une grande souplesse dans la journalisation des
    requêtes des clients. Les journaux sont écrits sous un format
    personnalisable, et peuvent être enregistrés directement dans un
    fichier, ou redirigés vers un programme externe. La journalisation
    conditionnelle est supportée, si bien que des requêtes individuelles
    peuvent être incluses ou exclues des journaux en fonction de leur
    caractéristiques.
    

    
    Ce module fournit trois directives : TransferLog crée un fichier
    journal, LogFormat
    définit un format personnalisé, et CustomLog définit un fichier journal et un format en
    une seule étape. Pour journaliser les requêtes dans plusieurs
    fichiers, vous pouvez utiliser plusieurs fois les directives
    TransferLog et
    CustomLog dans chaque serveur.
    

    


    top
    

    

    Formats de journaux personnalisés
    

    
    L'argument format des directives LogFormat et CustomLog est une chaîne de
    caractères. Cette chaîne définit le format de la journalisation des
    requêtes dans le fichier journal. Elle peut contenir des caractères
    littéraux qui seront reproduits dans le fichier journal, et les
    caractères de contrôle de style C "\n" et "\t" représentant
    respectivement une nouvelle ligne et une tabulation. Les guillemets
    et les anti-slashes littéraux doivent être échappés à l'aide
    d'anti-slashes.
    

    
    Les caractéristiques de la requête en elle-même sont journalisées
    en insérant des directives "%" dans la chaîne de
    format, celles-ci étant remplacées dans le fichier journal par
    certaines valeurs comme suit :
    

    
    Chaîne de format
        Description
    

    %%
        Le signe "pourcentage"
    

    %a
        L'adresse IP distante (voir le module
	mod_remoteip).
    

    %{c}a
        Adresse IP distante de la connexion(voir le module
	mod_remoteip)
    

    %A
        L'adresse IP locale
    

    %B
        La taille de la réponse en octets, en excluant les en-têtes
	HTTP.
    

    %b
        La taille de la réponse en octets, en excluant les en-têtes
	HTTP. Au format CLF , c'est à dire un '-' à la
	place d'un 0 lorsqu'aucun octet n'est renvoyé.
    

    %{NOMVAR}C
        Le contenu du cookie NOMVAR dans la requête
	envoyée au serveur. Seuls les cookies version 0 sont pleinement
	supportés.
    

    %D
        Le temps mis à servir la requête, en
	microsecondes.
    

    %{NOMVAR}e
        Le contenu de la variable d'environnement
	NOMVAR
    

    %f
        Nom de fichier
    

    %h
        Serveur distant. Contiendra l'adresse IP si la directive
	HostnameLookups est définie
	à Off, ce qui est sa valeur par défaut. Si cette
	adresse IP n'est enregistrée que pour certains serveurs, vous
	avez probablement défini des directives de contrôle d'accès qui
	mentionnent ces derniers par leurs noms. Voir la documentation de Require
	host.
    

    %{c}h
	Semblable à %h, mais exploite toujours le nom d'hôte de
	la connection TCP sous-jacente, en ignorant toute modification réalisée
	sur le nom d'hôte distant par des modules tels que
	mod_remoteip.
    

    %H
        Le protocole de la requête
    

    %{NOMVAR}i
        Le contenu des lignes d'en-tête
	NOMVAR: dans la requête envoyée au
	serveur. Ces en-têtes sont ajoutés par d'autres modules (par
	exemple mod_headers). Si vous êtes intéressé
	par ce qu'était l'en-tête de la requête avant d'être modifié
	par la plupart des modules, utilisez
	mod_setenvif pour copier l'en-tête dans une
	variable d'environnement interne et journaliser sa valeur via
	le champ %{VARNAME}e décrit plus haut.

        
    

    %k
        Nombre de requêtes persistantes en cours pour cette
	connexion. Interessant si la directive KeepAlive est utilisée ; par exemple,
	'1' signifie la première requête après la requête initiale, '2'
	la seconde, etc... ; autrement, il s'agit toujours de 0
	(indiquant la requête initiale).
    

    %l
        Le nom de connexion distant (en provenance d'identd, si
	disponible). Affiche un tiret, sauf si
	mod_ident est présent et si IdentityCheck est à
	On.
    

    %L
        L'identifiant du message de journalisation de la requête
	dans le journal des erreurs (ou '-' si aucun message n'a
	été enregistré dans le journal des erreurs pour cette requête)
    

    %m
        La méthode de la requête
    

    %{NOMVAR}n
        Le contenu de la note NOMVAR en provenance d'un
	autre module.
    

    %{NOMVAR}o
        Le contenu de la ligne d'en-tête
	NOMVAR: de la réponse.
    

    %p
        Le port canonique du serveur servant la requête
    

    %{format}p
        Le port canonique du serveur servant la requête ou le
	véritable port du serveur ou le véritable port du client. les
	formats valides sont canonical, local,
	ou remote.
        
    

    %P
        Le numéro de processus du processus enfant qui a servi la
	requête.
    

    %{format}P
        Le numéro de processus ou le numéro de thread du processus
	enfant qui a servi la requête. Les formats valides sont
	pid, tid, et hextid.
	hextid nécessite APR version 1.2.0 ou supérieure.
        
    

    %q
        La chaîne d'arguments (préfixée par un ? si une
	chaîne d'arguments existe, sinon une chaîne vide)
    

    %r
        La première ligne de la requête
    

    %R
        Le gestionnaire qui génère la réponse (s'il y en a un).
    

    %s
        Statut. Pour les requêtes redirigées en interne, il s'agit
	du statut de la requête *originale* --- %>s pour
	la dernière.
    

    %t
        Date à laquelle la requête a été reçue (au format anglais
	standard)
    

    %{format}t
        La date, sous la forme spécifiée par format, qui devrait
	être au format étendu strftime(3) (éventuellement
	localisé). Si le format commence par begin: (valeur
	par défaut), la date est extraite au début du traitement de la
	requête ; s'il commence par end:, la date
	correspond au moment où l'entrée du journal est inscrite, par
	conséquent vers la fin du traitement de la requête. Hormis les
	formats supportés par strftime(3), les formats
	suivants sont aussi disponibles :
        
    
        
    secnombre de secondes depuis Epoch
    
        
    msecnombre de millisecondes depuis  Epoch
    
        
    usecnombre de microsecondes depuis Epoch
    
        
    msec_fracfraction de milliseconde
    
        
    usec_fracfraction de microseconde
    
        
    
        Ces symboles ne peuvent pas être combinés entre eux ou avec un
	formatage strftime(3) dans la même chaîne de
	format. Par contre, vous pouvez utiliser plusieurs symboles
	%{format}t.
    

    %T
        Le temps mis pour servir la requête, en secondes.
    

    %{UNIT}T
        Le temps mis pour traiter la requête dans une unité définie
	par UNIT. Les valeurs d'unité valides sont
	ms pour millisecondes, us pour
	microsecondes et s pour secondes. Si
	UNIT est omis, la valeur de l'unité par défaut est
	la seconde ; spécifier la valeur d'unité us revient
	à utiliser le format %D. La possibilité de
	spécifier une valeur d'unité avec le format %T est
	disponible depuis la version 2.4.13 du serveur HTTP Apache.
    

    %u
        L'utilisateur distant (en provenance d'auth ; peut être faux
	si le statut de retour (%s) est 401).
    

    %U
        Le chemin de la requête, à l'exclusion de toute chaîne
	d'arguments.
    

    %v
        Le nom canonique du serveur qui a servi la requête, défini
	par la directive ServerName.
    

    %V
        La nom du serveur en tenant compte de la définition de la
	directive UseCanonicalName.
    

    %X
        Statut de la connexion lorsque la réponse a été renvoyée
	:

        
    
        
        
    X =
            connexion abandonnée avant l'envoi de la réponse.
    
        
    + =
            la connexion peut rester ouverte après l'envoi de la
	    réponse.
    
        
    - = 
            la connexion sera fermée après l'envoi de la
	    réponse.
    
        
    

        
    

    %I
        Le nombre d'octets reçus, en comptant la requête et les
	en-têtes, ne peut être nul. Nécessite l'activation de
	mod_logio.
    

    %O
        Nombre d'octets envoyés, y compris les en-têtes. Peut être
	nul dans les rares cas où une requête est avortée avant que la
	réponse ne soit envoyée. Nécessite l'activation de
	mod_logio.
    

    %S
        Nombre d'octets transmis (en émission et réception), y
	compris corps et en-têtes de requête. Ce nombre ne peut pas être
	nul, et il correspond à la combinaison des formats %I et %O.
	mod_logio doit être chargé pour pouvoir
	utiliser ce format.
    

    %{VARNAME}^ti
        Le contenu de VARNAME: dans les
	paramètres de la requête envoyée au serveur.
    

    %{VARNAME}^to
        Le contenu de VARNAME: dans les
	paramètres de la réponse envoyée par le serveur.
    

    

    
    Modificateurs
    

      
    Il est possible de restreindre l'enregistrement de certains
      éléments
      en fonction du code de statut de la réponse, en insérant une liste
      de codes de statut séparés par des virgules immédiatement après le
      caractère "%". Par exemple, "%400,501{User-agent}i"
      n'enregistrera l'en-tête User-agent que dans le cas
      d'une erreur 400 ou 501. Avec les autres codes de statut, c'est la
      chaîne littérale "-" qui sera enregistrée. La liste
      de codes peut être précédée d'un "!" pour inverser la
      condition : "%!200,304,302{Referer}i" enregistre
      l'en-tête Referer pour toutes les requêtes qui
      ne renvoient pas un des trois codes spécifiés.
    

      
    Les modificateurs "<" et ">" peuvent être utilisés pour
      les requêtes qui ont été redirigées en interne afin de choisir si
      c'est respectivement la requête originale ou finale qui doit être
      consultée. Par défaut, les directives %s, %U, %T, %D,
      et %r consultent la requête originale, alors que
      toutes les autres consultent la requête finale. Ainsi, par
      exemple, on peut utiliser %>s pour enregistrer le
      statut final de la requête, et %<u pour
      enregistrer l'utilisateur authentifié à l'origine pour une requête
      redirigée en interne vers une ressource sans authentification.
    

    

    
    Quelques Notes
    

      
    Pour des raisons de sécurité, à partir de la version 2.0.46,
      les caractères non imprimables et autres caractères spéciaux dans
      les directives %r, %i et %o
      doivent être échappés à l'aide des séquences
      \xhh,
      où hh est le code hexadécimal du caractère spécial.
      Comme exceptions à cette règle, les caractères " et
      \ doivent être échappés par un anti-slash, et tous
      les "blancs" doivent être écrits selon leur notation de style C
      (\n, \t, etc...). Avant la version
      2.0.46, aucun échappement n'était effectué sur ces chaînes, et il
      fallait être très prudent lors de l'exploitation des journaux
      bruts.
    

      
    A la différence de la version 1.3, depuis httpd 2.0, les chaînes
      de format %b et %B ne représentent pas
      le nombre d'octets envoyés au client, mais simplement la taille en
      octets de la réponse HTTP (les deux étant différents, par exemple,
      si la connexion est abandonnée, ou si SSL est utilisé). Le format
      %O fourni par mod_logio,
      enregistrera le nombre réel d'octets envoyés sur le réseau.
    

      
    Note : mod_cache est implémenté en tant que
      gestionnaire basique et non en tant que gestionnaire standard.
      C'est pourquoi la chaîne de format %R ne renverra pas
      d'information à propos du gestionnaire lorsqu'une mise en cache de
      contenu entre en jeu.
    

    

    
    Exemples
    

      
    Quelques chaînes de format couramment utilisées :
    

      
    
        
    Format de journal courant (CLF)
    
        
    "%h %l %u %t \"%r\" %>s %b"
    

        
    Format de journal courant avec un serveur virtuel
    
        
    "%v %h %l %u %t \"%r\" %>s %b"
    

        
    Format de journal NCSA étandu/combiné
    
        
    "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\"
        \"%{User-agent}i\""
    

        
    Format de journal de la page qui contient le lien vers la
	page concernée (Referer)
    
        
    "%{Referer}i -> %U"
    

        
    Format de journal de l'agent (Navigateur)
    
        
    "%{User-agent}i"
    
      
    

      
    Vous pouvez utiliser plusieurs fois la directive
      %{format}t pour construire un format de temps
      utilisant les symboles de format étendus tels que
      msec_frac :
    
      
    

    Format de temps prenant en compte les milisecondes
    

    "%{%d/%b/%Y %T}t.%{msec_frac}t %{%z}t"

    Considérations concernant la
sécurité
    
    
    Voir le document conseils à matière de
    sécurité pour plus de détails sur les raisons pour lesquelles
    votre sécurité pourrait être compromise, si le répertoire où sont
    stockés les fichiers journaux sont inscriptibles par tout autre
    utilisateur que celui qui démarre le serveur.

    Directive BufferedLogs
    

    

    Description:Enregistre les entrées du journal dans un tampon en mémoire
avant de les écrire sur disque
    

    Syntaxe:BufferedLogs On|Off
    

    Défaut:BufferedLogs Off
    

    Contexte:configuration globale
    

    Statut:Base
    

    Module:mod_log_config
    

    
    
    Lorsque la directive BufferedLogs est à
    "on", mod_log_config stocke de nombreuses entrées
    du journal en mémoire, et les écrit d'un seul bloc sur disque,
    plutôt que de les écrire après chaque requête. Sur certains
    systèmes, ceci peut améliorer l'efficacité des accès disque, et par
    conséquent les performances. La directive ne peut être définie
    qu'une seule fois pour l'ensemble du serveur ; elle ne peut pas être
    définie au niveau d'un serveur virtuel.
    

    
    Cette directive doit être utilisée avec
    précautions car un crash peut provoquer la perte de données de
    journalisation.
    


    

    top
    

    Directive CustomLog
    

    

    Description:Définit le nom et le format du fichier
journal
    

    Syntaxe:CustomLog  fichier|pipe
format|alias
[env=[!]variable-environnement|
expr=expression]
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_log_config
    

    
    
    La directive CustomLog permet de contrôler
    la journalisation des requêtes destinées au serveur. Un format de
    journal est spécifié, et la journalisation peut s'effectuer de
    manière conditionnelle en fonction des caractéristiques de la
    requête en utilisant des variables d'environnement.
    

    
    Le premier argument, qui spécifie l'emplacement où les journaux
    seront écrits, accepte deux types de valeurs :
    

    
    
      
    fichier
    
      
    Un nom de fichier, relatif au répertoire défini par la
      directive ServerRoot.
    

      
    pipe
    
      
    Le caractère pipe "|", suivi du chemin vers un
      programme qui recevra les informations de la journalisation sur
      son entrée standard. Voir les notes à propos de la journalisation redirigée pour plus
      d'informations.

      
    Sécurité :
    
      
    Si les journaux sont redirigés vers un programme, ce dernier
      s'exécutera sous l'utilisateur qui a démarré
      httpd. Ce sera l'utilisateur root si le serveur
      a été démarré par root ; vérifiez que le programme est
      sécurisé.
    
      
    
      
    Note
    
        
    Lors de la spécification d'un chemin de fichier sur les
	plate-formes non-Unix, il faut prendre soin de ne pas oublier
	que seuls les slashes directs doivent être utilisés, même si la
	plate-forme autorise l'emploi d'anti-slashes. D'une manière
	générale, c'est une bonne idée que de n'utiliser que des slashes
	directs dans les fichiers de configuration.
    
      
    
    
    

    
    Le second argument permet de définir ce qui va être écrit dans le
    fichier journal. Il peut contenir soit un alias prédéfini
    par une directive LogFormat, soit une chaîne de
    format explicite comme décrit dans la section formats de journaux.
    

    
    Par exemple, les deux blocs de directives suivants produisent le
    même effet :
    

    
    # Journal personnalisé avec alias de format
LogFormat "%h %l %u %t \"%r\" %>s %b" common
CustomLog "logs/access_log" common

# Journal personnalisé avec chaîne de format explicite
CustomLog "logs/access_log" "%h %l %u %t \"%r\" %>s %b"
    


    
    Le troisième argument est optionnel et permet de contrôler si une
    requête doit être ou non journalisée. Dans le cas d'une clause
    'env=!nom', la condition peut être la
    présence ou l'absence d'une variable particulière dans
    l'environnement du serveur. Dans le cas
    d'une clause 'expr=expression', la condition consiste
    en une expression booléenne
    quelconque. Si la condition n'est pas vérifiée, la requête ne sera
    pas journalisée. D'éventuelles références à des en-têtes HTTP dans
    l'expression rationnelle n'entraîneront pas l'ajout des noms
    d'en-tête correspondants à l'en-tête Vary.
    

    
    Les variables d'environnement peuvent être définies au niveau de
    chaque requête en utilisant les modules
    mod_setenvif et/ou mod_rewrite.
    Par exemple, si vous voulez enregistrer les requêtes pour toutes les
    images GIF sur votre serveur dans un fichier journal séparé, et pas
    dans votre journal principal, vous pouvez utiliser :
    

    
    SetEnvIf Request_URI \.gif$ gif-image
CustomLog "gif-requests.log" common env=gif-image
CustomLog "nongif-requests.log" common env=!gif-image
    


    
    Ou, pour reproduire le comportement de l'ancienne directive
    RefererIgnore, vous pouvez utiliser :
    

    
    SetEnvIf Referer example\.com localreferer
CustomLog "referer.log" referer env=!localreferer

    Compatibilité:Disponible à partir de la version 2.4.19 du serveur HTTP Apache
    

    

    
    La directive GlobalLog permet de spécifier un
    journal partagé entre le serveur principal et tous les serveurs virtuels

    Directive LogFormat
    

    

    Description:Décrit un format utilisable dans un fichier
journal
    

    Syntaxe:LogFormat format|alias
[alias]
    

    Défaut:LogFormat "%h %l %u %t \"%r\" %>s %b"
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_log_config
    

    
    
    Cette directive permet de spécifier le format du fichier journal
    des accès.
    

    
    La directive LogFormat se présente sous
    deux formes. Sous la première forme, qui ne possède qu'un seul
    argument, la directive définit le format qui sera utilisé dans les
    journaux spécifiés par les directives
    TransferLog ultérieures. L'argument unique
    peut contenir un format explicite comme décrit dans la
    section formats de journaux personnalisés
    ci-dessus. Il peut aussi contenir un alias faisant
    référence à un format de journal prédéfini par une directive
    LogFormat comme décrit plus loin.
    

    
    Sous sa seconde forme, la directive
    LogFormat associe un format
    explicite à un alias. Cet alias peut
    ensuite s'utiliser dans les directives
    LogFormat ou CustomLog ultérieures, ce qui
    évite d'avoir à répéter l'ensemble de la chaîne de format. Une
    directive LogFormat qui définit un alias
    ne fait rien d'autre -- c'est à dire qu'elle ne
    fait que définir l'alias, elle n'applique pas le format et n'en
    fait pas le format par défaut. Par conséquent, elle n'affecte pas
    les directives TransferLog ultérieures. En
    outre, la directive LogFormat ne peut pas
    utiliser un alias pour en définir un autre. Notez que l'alias ne
    doit pas contenir de caractère pourcent (%).
    

    
    Exemple
    LogFormat "%v %h %l %u %t \"%r\" %>s %b" serveur_virtuel_commun

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_log_config
    

    
    
    Cette directive possède exactement les mêmes arguments et produit
    les mêmes effets que la directive CustomLog, à l'exception qu'elle
    ne permet pas de spécifier un format de journal explicite ou la
    journalisation conditionnelle des requêtes. En l'occurrence, le
    format de journal est déterminé par la dernière définition d'une
    directive LogFormat
    qui ne définit pas d'alias. Si aucun format particulier n'a été
    spécifié, c'est le Common Log Format qui sera utilisé.
    

    
    Exemple
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""
TransferLog logs/access_log

mod_proxy
    

    Status:Extension

    Source File:mod_proxy_ajp.c
    

    Compatibility:Available in version 2.1 and later
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the
    Apache JServ Protocol version 1.3 (hereafter
    AJP13).
    

    
    Thus, in order to get the ability of handling AJP13
    protocol, mod_proxy and
    mod_proxy_ajp have to be present in the server.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.

    Usage
    
    
    This module is used to reverse proxy to a backend application server
    (e.g. Apache Tomcat) using the AJP13 protocol. The usage is similar to
    an HTTP reverse proxy, but uses the ajp:// prefix:
    

    
    Simple Reverse Proxy
    ProxyPass "/app" "ajp://backend.example.com:8009/app"
    

    

    
    Options such as the secret option of Tomcat (required by
    default since Tomcat 8.5.51 and 9.0.31) can just be added as a separate
    parameter at the end of ProxyPass
    or BalancerMember. This parameter
    is available in Apache HTTP Server 2.4.42 and later:
    
    
    Simple Reverse Proxy with secret option
    ProxyPass "/app" "ajp://backend.example.com:8009/app" secret=YOUR_AJP_SECRET
    

    

    
    Balancers may also be used:
    
    
    Balancer Reverse Proxy
    <Proxy "balancer://cluster">
    BalancerMember "ajp://app1.example.com:8009" loadfactor=1
    BalancerMember "ajp://app2.example.com:8009" loadfactor=2
    ProxySet lbmethod=bytraffic
</Proxy>
ProxyPass "/app" "balancer://cluster/app"
    

    

    
    Note that usually no
    ProxyPassReverse
    directive is necessary. The AJP request includes the original host
    header given to the proxy, and the application server can be expected
    to generate self-referential headers relative to this host, so no
    rewriting is necessary.
    

    
    The main exception is when the URL path on the proxy differs from that
    on the
    backend. In this case, a redirect header can be rewritten relative to the
    original host URL (not the backend ajp:// URL), for
    example:
    
    
    Rewriting Proxied Path
    ProxyPass "/apps/foo" "ajp://backend.example.com:8009/foo"
ProxyPassReverse "/apps/foo" "http://www.example.com/foo"
    

    
    
    However, it is usually better to deploy the application on the backend
    server at the same path as the proxy rather than to take this approach.

    Environment Variables
    
    
    Environment variables whose names have the prefix AJP_
    are forwarded to the origin server as AJP request attributes
    (with the AJP_ prefix removed from the name of the key).

    Overview of the protocol
    
    
    The AJP13 protocol is packet-oriented.  A binary format
    was presumably chosen over the more readable plain text for reasons of
    performance.  The web server communicates with the servlet container over
    TCP connections.  To cut down on the expensive process of socket creation,
    the web server will attempt to maintain persistent TCP connections to the
    servlet container, and to reuse a connection for multiple request/response
    cycles.
    
    
    Once a connection is assigned to a particular request, it will not be
    used for any others until the request-handling cycle has terminated.  In
    other words, requests are not multiplexed over connections.  This makes
    for much simpler code at either end of the connection, although it does
    cause more connections to be open at once.
    
    
    Once the web server has opened a connection to the servlet container,
    the connection can be in one of the following states:
    
    
      
    
    •  Idle 
       No request is being handled over this connection. 
      • 
    
    •  Assigned 
       The connection is handling a specific request.
      • 
    
    
    
    Once a connection is assigned to handle a particular request, the basic
    request information (e.g. HTTP headers, etc) is sent over the connection in
    a highly condensed form (e.g. common strings are encoded as integers).
    Details of that format are below in Request Packet Structure. If there is a
    body to the request (content-length > 0), that is sent in a
    separate packet immediately after.
    
    
    At this point, the servlet container is presumably ready to start
    processing the request.  As it does so, it can send the
    following messages back to the web server:
    
    
      
    
    • SEND_HEADERS 
      Send a set of headers back to the browser.
      • 
    
    • SEND_BODY_CHUNK 
      Send a chunk of body data back to the browser.
    
      • 
    
    • GET_BODY_CHUNK 
      Get further data from the request if it hasn't all
    been transferred yet.  This is necessary because the packets have a fixed
    maximum size and arbitrary amounts of data can be included the body of a
    request (for uploaded files, for example).  (Note: this is unrelated to
    HTTP chunked transfer).
      • 
    
    • END_RESPONSE 
       Finish the request-handling cycle.
      • 
    
    
    
    Each message is accompanied by a differently formatted packet of data.
    See Response Packet Structures below for details.

    Basic Packet Structure
    
    
    There is a bit of an XDR heritage to this protocol, but it differs
    in lots of ways (no 4 byte alignment, for example).
    
    
    AJP13 uses network byte order for all data types.
    
    
    There are four data types in the protocol: bytes, booleans,
    integers and strings.
    
    
    
    
    Byte
    A single byte.
    
    
    Boolean
    
      
    A single byte, 1 = true, 0 = false.
      Using other non-zero values as true (i.e. C-style) may work in some places,
      but it won't in others.
    
    
    Integer
    
      
    A number in the range of 0 to 2^16 (32768).  Stored in
      2 bytes with the high-order byte first.
    
    
    String
    
      
    A variable-sized string (length bounded by 2^16). Encoded with
      the length packed into two bytes first, followed by the string
      (including the terminating '\0').  Note that the encoded length does
      not include the trailing '\0' -- it is like
      strlen.  This is a touch confusing on the Java side, which
      is littered with odd autoincrement statements to skip over these
      terminators.  I believe the reason this was done was to allow the C
      code to be extra efficient when reading strings which the servlet
      container is sending back -- with the terminating \0 character, the
      C code can pass around references into a single buffer, without copying.
      if the \0 was missing, the C code would have to copy things out in order
      to get its notion of a string.
    
    
    

  
    Packet Size
    
    
    According to much of the code, the max packet size is 
    8 * 1024 bytes (8K).  The actual length of the packet is encoded in
    the header.
    
  
  
    Packet Headers
    
    
    Packets sent from the server to the container begin with
    0x1234.  Packets sent from the container to the server
    begin with AB (that's the ASCII code for A followed by the
    ASCII code for B).  After those first two bytes, there is an integer
    (encoded as above) with the length of the payload.  Although this might
    suggest that the maximum payload could be as large as 2^16, in fact, the
    code sets the maximum to be 8K.
    
    
    
       
      
    
        Packet Format (Server->Container)
      
    
      
    
        Byte
        0
        1
        2
        3
        4...(n+3)
      
    
      
    
        Contents
        0x12
        0x34
        Data Length (n)
        Data

        Byte
        0
        1
        2
        3

        A
        B
        Data Length (n)
        Data
      
    
    
    
    
    For most packets, the first byte of the payload encodes the type of
     message.  The exception is for request body packets sent from the server to
     the container -- they are sent with a standard packet header (
     0x1234 and then length of the packet), but without any prefix code
     after that.
    
     
    The web server can send the following messages to the servlet
     container:

        Forward Request
        Begin the request-processing cycle with the following data
      
    
      
    
        7
        Shutdown
        The web server asks the container to shut itself down.
      
    
      
    
        8
        Ping
        The web server asks the container to take control
        (secure login phase).
      
    
      
    
        10
        CPing
        The web server asks the container to respond quickly with a CPong.
        
      
    
      
    
        none
        Data
        Size (2 bytes) and corresponding body data.
      
    
    
    
    
    To ensure some basic security, the container will only actually do the
    Shutdown if the request comes from the same machine on which
    it's hosted.
    
    
    The first Data packet is send immediately after the
    Forward Request by the web server.
    
    
    The servlet container can send the following types of messages to the
    webserver:
    
    
    
       
      
    
        Code
        Type of Packet
        Meaning
      
    
      
    
        3
        Send Body Chunk
        Send a chunk of the body from the servlet container to the web
        server (and presumably, onto the browser). 
      
    
      
    
        4
        Send Headers
        Send the response headers from the servlet container to the web
        server (and presumably, onto the browser).
      
    
      
    
        5
        End Response
        Marks the end of the response (and thus the request-handling cycle).
        
      
    
      
    
        6
        Get Body Chunk
        Get further data from the request if it hasn't all been
        transferred yet.

    Each of the above messages has a different internal structure, detailed
    below.
    
  

    top
    

    

    Request Packet Structure
    
    
    For messages from the server to the container of type
    Forward Request:
    
    
    AJP13_FORWARD_REQUEST :=
    prefix_code      (byte) 0x02 = JK_AJP13_FORWARD_REQUEST
    method           (byte)
    protocol         (string)
    req_uri          (string)
    remote_addr      (string)
    remote_host      (string)
    server_name      (string)
    server_port      (integer)
    is_ssl           (boolean)
    num_headers      (integer)
    request_headers *(req_header_name req_header_value)
    attributes      *(attribut_name attribute_value)
    request_terminator (byte) OxFF
    
    
    The request_headers have the following structure:
    
    req_header_name :=
    sc_req_header_name | (string)  [see below for how this is parsed]

sc_req_header_name := 0xA0xx (integer)

req_header_value := (string)
    
    
    The attributes are optional and have the following
    structure:
    
    
    attribute_name := sc_a_name | (sc_a_req_attribute string)

attribute_value := (string)
    
    
    Not that the all-important header is content-length,
    because it determines whether or not the container looks for another
    packet immediately.

    protocol, req_uri, remote_addr, remote_host, server_name,
  server_port, is_ssl
    
    
    These are all fairly self-explanatory.  Each of these is required, and
    will be sent for every request.
    
  
  
    Headers
    
    
    The structure of request_headers is the following:
    First, the number of headers num_headers is encoded.
    Then, a series of header name req_header_name / value
    req_header_value pairs follows.
    Common header names are encoded as integers,
    to save space.  If the header name is not in the list of basic headers,
    it is encoded normally (as a string, with prefixed length).  The list of
    common headers sc_req_header_nameand their codes
    is as follows (all are case-sensitive):

    The Java code that reads this grabs the first two-byte integer and if
    it sees an '0xA0' in the most significant
    byte, it uses the integer in the second byte as an index into an array of
    header names.  If the first byte is not 0xA0, it assumes that
    the two-byte integer is the length of a string, which is then read in.
    
    
    This works on the assumption that no header names will have length
    greater than 0x9FFF (==0xA000 - 1), which is perfectly
    reasonable, though somewhat arbitrary.
    
    
    Note:
    
    The content-length header is extremely
    important.  If it is present and non-zero, the container assumes that
    the request has a body (a POST request, for example), and immediately
    reads a separate packet off the input stream to get that body.
    
    
  
  
    Attributes
    
    
    The attributes prefixed with a ?
    (e.g. ?context) are all optional.  For each, there is a
    single byte code to indicate the type of attribute, and then its value
    (string or integer).  They can be sent in any order (though the C code
    always sends them in the order listed below).  A special terminating code
    is sent to signal the end of the list of optional attributes. The list of
    byte codes is:
    
    
    
      
    InformationCode ValueType Of ValueNote
    
      
    ?context0x01-Not currently implemented
      
    
      
    ?servlet_path0x02-Not currently implemented
      
    
      
    ?remote_user0x03String
    
      
    ?auth_type0x04String
    
      
    ?query_string0x05String
    
      
    ?jvm_route0x06String
    
      
    ?ssl_cert0x07String
    
      
    ?ssl_cipher0x08String
    
      
    ?ssl_session0x09String
    
      
    ?req_attribute0x0AStringName (the name of the
      attribute follows)
    
      
    ?ssl_key_size0x0BInteger
    
      
    ?secret0x0CStringSupported since 2.4.42
    
      
    are_done0xFF-request_terminator
    
    
    
    
    The context and servlet_path are not
    currently set by the C code, and most of the Java code completely ignores
    whatever is sent over for those fields (and some of it will actually break
    if a string is sent along after one of those codes).  I don't know if this
    is a bug or an unimplemented feature or just vestigial code, but it's
    missing from both sides of the connection.
    
    
    The remote_user and auth_type presumably
    refer to HTTP-level authentication, and communicate the remote user's
    username and the type of authentication used to establish their identity
    (e.g. Basic, Digest).
    
    
    The query_string, ssl_cert,
    ssl_cipher, ssl_session and
    ssl_key_size refer to the
    corresponding pieces of HTTP and HTTPS.
    
    
    The jvm_route, is used to support sticky
    sessions -- associating a user's sesson with a particular Tomcat instance
    in the presence of multiple, load-balancing servers.
    
    
    The secret is sent when the secret=secret_keyword
    parameter is used in
    ProxyPass or
    BalancerMember directives.
    The backend needs to support secret and the values must match.
    request.secret or requiredSecret are documented in the AJP
    configuration of the Apache Tomcat.
    
    
    Beyond this list of basic attributes, any number of other attributes
    can be sent via the req_attribute code 0x0A.
    A pair of strings to represent the attribute name and value are sent
    immediately after each instance of that code.  Environment values are passed
    in via this method.
    
    
    Finally, after all the attributes have been sent, the attribute
    terminator, 0xFF, is sent.  This signals both the end of the
    list of attributes and also then end of the Request Packet.

    Response Packet Structure
    
    
    for messages which the container can send back to the server.
    
    
    AJP13_SEND_BODY_CHUNK :=
  prefix_code   3
  chunk_length  (integer)
  chunk        *(byte)
  chunk_terminator (byte) Ox00


AJP13_SEND_HEADERS :=
  prefix_code       4
  http_status_code  (integer)
  http_status_msg   (string)
  num_headers       (integer)
  response_headers *(res_header_name header_value)

res_header_name :=
    sc_res_header_name | (string)   [see below for how this is parsed]

sc_res_header_name := 0xA0 (byte)

header_value := (string)

AJP13_END_RESPONSE :=
  prefix_code       5
  reuse             (boolean)


AJP13_GET_BODY_CHUNK :=
  prefix_code       6
  requested_length  (integer)
    
  
    Details:
    
  
    Send Body Chunk
    
    
    The chunk is basically binary data, and is sent directly back to the
    browser.
    
  
  
    Send Headers
    
    
    The status code and message are the usual HTTP things
    (e.g. 200 and OK). The response header names are
    encoded the same way the request header names are. See header_encoding above
    for details about how the codes are distinguished from the strings.
    
    The codes for common headers are:
    
    
    
      
    NameCode value
    
      
    Content-Type0xA001
    
      
    Content-Language0xA002
    
      
    Content-Length0xA003
    
      
    Date0xA004
    
      
    Last-Modified0xA005
    
      
    Location0xA006
    
      
    Set-Cookie0xA007
    
      
    Set-Cookie20xA008
    
      
    Servlet-Engine0xA009
    
      
    Status0xA00A
    
      
    WWW-Authenticate0xA00B
    
    
    
    
     After the code or the string header name, the header value is
    immediately encoded.
    
  
  
    End Response
    
    
    Signals the end of this request-handling cycle.  If the
    reuse flag is true (anything other than 0 in the actual
    C code), this TCP connection can now be used to handle new incoming
    requests.  If reuse is false (==0), the connection should
    be closed.
    
  
  
    Get Body Chunk
    
    
    The container asks for more data from the request (If the body was
    too large to fit in the first packet sent over or when the request is
    chunked). The server will send a body packet back with an amount of data
    which is the minimum of the request_length, the maximum send
    body size (8186 (8 Kbytes - 6)), and the number of bytes
    actually left to send from the request body.
    
    If there is no more data in the body (i.e. the servlet container is
    trying to read past the end of the body), the server will send back an
    empty packet, which is a body packet with a payload length of 0.
    (0x12,0x34,0x00,0x00)

    Identificateur de Module:allowmethods_module
    

    Fichier Source:mod_allowmethods.c
    

    Compatibilité:Disponible à partir de la version 2.3 du serveur HTTP Apache
    

    Sommaire
    


    Ce module permet de restreindre aisément les méthodes HTTP
pouvant être utilisées sur le serveur. La configuration la plus courante
est du style :
    


    <Location "/">
   AllowMethods GET POST OPTIONS
</Location>
    



    



    top
    

    Directive AllowMethods
    

    

    Description:Restreint l'accès aux méthodes HTTP spécifiées
    

    Syntaxe:AllowMethods reset|HTTP-method
[HTTP-method]...
    

    Défaut:AllowMethods reset
    

    Contexte:répertoire
    

    Statut:Expérimental
    

    Module:mod_allowmethods
    

    


    Les noms des méthodes HTTP sont sensibles à la casse, et sont en
général définis en majuscules, comme dans les RFCs. Les méthodes GET et
HEAD sont considérées comme équivalentes. Le mot-clé
reset permet de désactiver
mod_allowmethods dans les niveaux inférieurs
d'imbrication :
    


    <Location "/svn">
   AllowMethods reset
</Location>
    



    Avertissement
    
  
    La méthode TRACE ne peut pas être rejetée par ce module ; pour ce
  faire, vous devez utiliser la directive TraceEnable.
    

    


    Le module mod_allowmethods a été écrit pour
remplacer l'implémentation "bricolée" des directives Limit et LimitExcept.

    Module Apache mod_proxy_fdpass
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Module fournissant le support des processus externes fdpass
à mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_fdpass_module
    

    Fichier Source:mod_proxy_fdpass.c
    

    Compatibilité:Disponible pour unix depuis la version 2.3
d'Apache
    

    Sommaire
    

    
    Pour fonctionner, ce module nécessite le chargement de
    mod_proxy. Il permet le passage de la socket du client
    vers un autre processus.
    

    
    mod_proxy_fdpass utilise la capacité des sockets de
    domaine AF_UNIX à transmettre un
    descripteur de fichier ouvert afin de permettre à un autre
    processus de terminer le traitement de la requête.
    
    

    
    Le module possède une interface de fournisseur
    proxy_fdpass_flusher qui permet éventuellement à un
    autre module d'envoyer les en-têtes de la réponse, ou même le début
    du corps de la réponse. Le fournisseur par défaut flush désactive la
    persistence, et envoie les en-têtes de la réponse, laissant le soin
    au processus externe d'envoyer le corps de la réponse.
    

    
    Pour utiliser un autre fournisseur, vous devez spécifier le paramètre
    flusher de la directive ProxyPass.
    
    

    
    À l'heure actuelle, la seule donnée transmise au processus
    externe est la socket du client. Pour recevoir une socket client,
    appelez recvfrom avec une structure struct cmsghdr allouée. Les versions
    futures de ce module pourront transmettre d'autres données que le
    socket client.
    
    

    

    Support Apache!

    Description:Filter Input (request) and Output (response) content using sed syntax
    

    Status:Experimental
    

    Module Identifier:sed_module
    

    Source File:mod_sed.c sed0.c sed1.c regexp.c regexp.h sed.h
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    


    
mod_sed is an in-process content filter. The mod_sed filter implements the sed editing
commands implemented by the Solaris 10 sed
program as described in the manual
page. However, unlike sed, mod_sed doesn't take data from
standard
input. Instead, the filter acts on the entity data sent between client and
server. mod_sed can be used as an input or output filter. mod_sed is a
content filter, which means that it cannot be used to modify client or
server http headers.

    

    
The mod_sed output filter accepts a chunk of data, executes the sed scripts on the data, and generates the output which is passed to the next filter in the chain.

    


    
The mod_sed input filter reads the data from the next filter in the chain, executes the sed scripts, and returns the generated data to the caller filter in the filter chain.

    


    
Both the input and output filters only process the data if newline characters are seen in the content. At the end of the data, the rest of the data is treated as the last line.

    Sample Configuration
    
    
    Adding an output filter 
    # In the following example, the sed filter will change the string
# "monday" to "MON" and the string "sunday" to SUN in html documents
# before sending to the client.
<Directory "/var/www/docs/sed"> 
    AddOutputFilter Sed html 
    OutputSed "s/monday/MON/g" 
    OutputSed "s/sunday/SUN/g" 
</Directory>
    

    

    
    Adding an input filter 
    # In the following example, the sed filter will change the string
# "monday" to "MON" and the string "sunday" to SUN in the POST data
# sent to PHP.

    AcceptFilter Yönergesi
    

    

    Açıklama:Bir protokolün dinleyici soketleri için en iyilemeleri ayarlar

    

    Sözdizimi:AcceptFilter protocol kabul_süzgeci
    

    Bağlam:sunucu geneli
    

    Durum:Çekirdek
    

    Modül:core
    

    
    
    Bu yönerge Protocol yönergesinde belirtilen
      protokol türüne göre bir dinleme soketinin işletim
      sistemine özgü en iyilemelerini etkin kılar. İşletim sistemi çekirdeği
      için temel önerme veri alınıncaya kadar veya HTTP isteğinin tamamı
      tamponlanana kadar sunucu sürecine bir soket tahsis etmemektir.
      Şimdilik sadece FreeBSD’nin Kabul Süzgeçleri ve Linux’un soket seçeneklerinden
      TCP_DEFER_ACCEPT ve Windows'un en iyilenmiş
      AcceptEx() işlevi desteklenmektedir.
    

    
    Değiştirge olarak none kullanımı, protokolün kabul
      süzgeçlerini iptal edecektir. ftp: veya nntp
      gibi sunucunun baştan bir veri göndermesinin gerekli olduğu
      protokoller için kullanışlıdır. Örnek:
    

    
    AcceptFilter nntp none
    


    
    Öntanımlı protokol isimleri port 443 için https ve tüm
      diğer portlar için http'dir. Dinlenmesi için başka bir port
      ile ilgili bir protokol belirtmek isterseniz Listen yönergesine protokol
      argümanını ekleyin.
    

    
    FreeBSD için öntanımlı değerler:
    
    
    AcceptFilter http httpready
AcceptFilter https dataready
    


    
    httpready kabul süzgeci HTTP isteklerinin tamamını
      işletim sistemi çekirdeği seviyesinde tamponlar. Çekirdek isteğin
      tamamını alır almaz sunucuya gönderir. Ayrıntılar için accf_http(9) kılavuz sayfasına bakınız. HTTPS istekleri
      şifrelenmiş olduğundan sadece accf_data(9) süzgeci kullanılır.
    

    
    Linux’taki öntanımlı değerler:
    
    
    AcceptFilter http data
AcceptFilter https data
    


    
    Linux’un TCP_DEFER_ACCEPT soket seçeneği HTTP isteklerinin
      tamponlanmasını desteklemez.  none dahil her değer
      dinleyici üzerinde TCP_DEFER_ACCEPT seçeneğini etkin kılar.
      Daha ayrıntılı bilgi edinmek için Linux
      tcp(7) kılavuz sayfasına bakınız.
    

    
    Windows’taki öntanımlı değerler::
    

    
    AcceptFilter http connect
AcceptFilter https connect
    


    
    Windows'un mpm_winnt modülü AcceptEx()
      arayüzünü açıp kapamak için AcceptFilter'i yorumlar ve
      http protokol tamponlamasını desteklemez. connect, AcceptEx() arayüzünü kullanacak, ayrıca uç ağ adresleri de alınacak, fakat none gibi connect seçeneği de ilk veri aktarımını beklemeyecektir.
    

    
    Windows'ta none AcceptEx()'ten ziyade
      accept() kullanır ve ağ soketlerini bağlantılar arasında
      yer değiştirmez. Sürücü desteği bozuk ağ bağdaştırıcılarından başka
      vpn sürücüleri gibi bazı sanal ağ sağlayıcılar veya spam, virus veya
      casus yazılım süzgeçleri için kullanışlıdır.
    

    
    
      
    data AcceptFilter (Windows)
    

      
    2.4.23 ve öncesi sürümlerde, Windows data accept
         süzgeci veri aktarılana kadar bekletildikten sonra ilk veri
         tamponlanır ve uç ağ adresi için tek bir AcceptEx() çağrısı yapılır.
         Bu gerçeklenim hizmet reddi saldırısına konu olduğundan iptal
         edilmiştir.
    

      
    httpd'nin şu anki dağıtımları için Windows'da connect
        süzgeci öntanımlıdır ve data belirtilmiş olsa dahi
        connect belirtilmiş gibi davranılır. Önceki sürümleri
        kullananların AcceptFilter satırını yukarıdaki gibi
        connect süzgecine ayarlamaları gerekmektedir.

    AcceptPathInfo Yönergesi
    

    

    Açıklama:Dosya isminden sonra belirtilen yol verisini kabul veya
  reddeder.
    

    Sözdizimi:AcceptPathInfo On|Off|Default
    

    Öntanımlı:AcceptPathInfo Default
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:FileInfo
    

    Durum:Çekirdek
    

    Modül:core
    

    
    
    Bu yönerge, istekte dosya isminden sonra (dizinde belirtilen dosya
      bulunmayabilir) belirtilen yol verisinin kabul edilip edilmeyeceğini
      denetler. Dosya isminden sonra belirtilen yol verisi
      PATH_INFO ortam değişkeninde betiklerin kullanımına
      sunulabilir.
    

    
    Örneğin, içinde sadece here.html dosyası bulunan bir
      /test/ dizinimiz olsun. /test/here.html/more
      ve /test/nothere.html/more isteklerinin her ikisi de
      PATH_INFO değişkenine /more verisinin
      atanmasını sağlar.
    

    
    AcceptPathInfo yönergesine atanabilecek argüman
      sayısı üçtür:
    
    
    
    
    Off
    Sadece dosya isminden sonra yol verisi
      bulunmayan istekler kabul edilir. Yukarıdaki örnekteki gibi
      /test/here.html/more şeklindeki istekler bir 404 (Nesne
      bulunamadı) hatasıyla sonuçlanır.
    

    
    On
    Mevcut bir dosyaya ait bir dosya isminden
      sonra bir yol verisinin de belirtildiği istekler kabul edilir.
      Yukarıdaki örnekteki gibi /test/here.html/more şeklindeki
      istekler, /test/here.html geçerli bir dosya olduğu
      takdirde kabul edilir.
    

    
    Default
    Dosya isminden sonra yol verisi
      belirtilen isteklerin nasıl ele alınacağı istekten sorumlu eylemci tarafından saptanır. Normal dosyalar
      için çekirdek eylemci öntanımlı olarak PATH_INFO
      isteklerini reddeder. cgi-script ve isapi-handler gibi betiklere
      hizmet eden eylemciler ise genellikle PATH_INFO
      isteklerini öntanımlı olarak kabul ederler.
    
    
    

    
    AcceptPathInfo yönergesinin birincil amacı eylemcinin
      PATH_INFO istekleri hakkında verdiği kabul veya red
      kararını geçersiz kılabilmenizi sağlamaktır. Örneğin,
      PATH_INFO’ya dayalı olarak içerik üretmek için INCLUDES gibi bir süzgeç kullandığınız takdirde bu
      geçersizleştirme zorunlu olur. Normal dosyalar için çekirdek eylemci
      normal olarak isteği reddederdi, böyle bir durumda bir betiği etkin
      kılmak için aşağıdaki gibi bir yapılandırma kullanabilirsiniz:
    

    
    <Files "mypaths.shtml">
  Options +Includes
  SetOutputFilter INCLUDES
  AcceptPathInfo On
</Files>

    AccessFileName Yönergesi
    

    

    Açıklama:Dağıtık yapılandırma dosyasının ismi belirtilir.
    

    Sözdizimi:AccessFileName filename [filename] ...
    

    Öntanımlı:AccessFileName .htaccess
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Çekirdek
    

    Modül:core
    

    
    
    Belge yolu üzerindeki dizinlerde dağıtık yapılandırma dosyalarının bulunmasına izin verilmişse sunucu bir isteği
      işlerken önce bu dizinlerde bu yönergede belirtilmiş yapılandırma
      dosyasını arar. Örnek:
    

    
    AccessFileName .acl
    


    
    Sunucu, /usr/local/web/index.html belgesini döndürmeden
      önce,
    

    
    <Directory "/">
    AllowOverride None
</Directory>
    


    
    şeklinde bir yapılandırma ile iptal edilmiş olmadıkça yönergeler için
      /.acl, /usr/.acl,
      /usr/local/.acl ve /usr/local/web/.acl
      dosyalarını okur.

    AddDefaultCharset Yönergesi
    

    

    Açıklama:Bir yanıtın içerik türü text/plain veya
  text/html olduğunda eklenecek öntanımlı karakter kümesi
  parametresini belirler.
    

    Sözdizimi:AddDefaultCharset On|Off|karküm
    

    Öntanımlı:AddDefaultCharset Off
    

    Bağlam:sunucu geneli, sanal konak, dizin, .htaccess
    

    Geçersizleştirme:FileInfo
    

    Durum:Çekirdek
    

    Modül:core
    

    
    
    Bu yönerge, yanıtın içerik türü text/plain veya
      text/html olmak şartıyla yanıta eklenecek karakter
      kümesini (karakter kodlamasınının ismini) belirler. Bu, asıl davranış
      çoğunlukla kullanıcının istemci yapılandırmasına bağlı olmakla
      birlikte, yanıtın gövdesinde META elemanı vasıtasıyla
      belirtilmiş karakter kümesini geçersiz kılar. AddDefaultCharset
      Off şeklinde bir atama bu işlevselliği iptal eder.
      AddDefaultCharset On ile bu işlevsellik etkin kılınmaktan
      başka iso-8859-1 karakter kümesini öntanımlı olarak yanıta
      eklenir. Yönergede karküm olarak belirtilecek değerler,
      Genel Ağ ortam türlerinde (MIME türlerinde) kullanmak üzere IANA’da kayıtlı
      karakter kümesi değerlerinden biri olmalıdır. Örnek:
    

    
    AddDefaultCharset utf-8
    


    
    AddDefaultCharset yönergesi sadece, metin
      kaynaklarının hepsinin aynı karakter kümesine sahip olduğu bilindiği
      takdirde ve her birinde ayrı ayrı karakter kümesi belirtmek çok
      külfetli olacaksa kullanılmalıdır. Buna bir örnek, CGI betikleri
      tarafından üretilmiş içeriğe sahip kaynaklara karakter kümesinin
      eklenmesidir; böyle kaynaklar çıktıda kullanıcı tarafından sağlanmış
      veri içermeleri nedeniyle karşı siteden kaynaklanan betikli
      saldırılardan zarar görebilir. Bununla birlikte, bir öntanımlı karakter
      kümesi belirtmek, tarayıcılarında “karakter kodlamasını kendiliğinden
      sapta” özelliğini etkin kılmış kullanıcıları korumayacağından daha iyi
      bir çözüm bu betikleri bu tür saldırılara karşı düzeltmek veya en iyisi
      silmektir.

    AllowEncodedSlashes Yönergesi
    

    

    Açıklama:Kodlanmış dosya yolu ayracı içeren URL’lere izin verilip
  verilmeyeceğini belirler.
    

    Sözdizimi:AllowEncodedSlashes On|Off|NoDecode
    

    Öntanımlı:AllowEncodedSlashes Off
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Çekirdek
    

    Modül:core
    

    Uyumluluk:NoDecode seçeneği Apache httpd 2.3.12 ve sonrasında
  mevcuttur.
    

    
    
    AllowEncodedSlashes yönergesi kodlanmış dosya
      yolu ayracı içeren URL’lere izin verir (/ yerine
      %2F ve ek olarak \ için ilgili sistemlerde
      %5C kullanılmış URL’ler).
    

    
    Off öntanımlı değeriyle, böyle URL’ler bir 404
      (Nesne bulunamadı) hatasıyla reddedilirler.
    

    
    On değeriyle, böyle URL’ler kabul edilir ve kodlanmış
      dosya yolu ayraçları kodlanmış diğer karakterler gibi çözümlenir.
    

    
    NoDecode değeriyle, böyle URL’ler kabul edilir fakat
      kodlanmış dosya yolu ayraçları çözümlenmeden kodlanmış halde
      bırakılır.
    

    
    AllowEncodedSlashes On, çoğunlukla
      PATH_INFO ile bir arada kullanıldığı zaman
      kullanışlıdır.
    

    
    Ek Bilgi
    
      
    Kodlanmış bölü çizgileri yol bilgisi için gerekliyse bir güvenlik
      ölçütü olarak NoDecode kullanımı şiddetle önerilir.
      Kodlanmış bölü çizgilerinin çözümlenmesine izin vermek güvensiz olması
      olası yollara izin vermek olurdu.

    Konak erişimini denetleyen
        Allow,
        Deny ve
        Order
        yönergelerinin kullanımına izin verilir.
    

      
    Nonfatal=[Override|Unknown|All]
    

      
    .htaccess dosyalarındaki sözdizimi
        hatalarının ölümcül olarak ele alınmaması için
        AllowOverride yönergesinin kullanımına izin verir; bunun
        yerine bir dahili sunucu hatasına sebep olur, izin verilmeyen veya
        tanınmayan yönergeler yoksayılır ve günlüğe bir uyarı çıktılanır:
        
      
          
    • Nonfatal=Override ile
            AllowOverride tarafından yasaklanmış yönergeler
            ölümcül olarak ele alınmaz.
      • 
          
    • Nonfatal=Unknown ile bilinmeyen yönergeler
            ölümcül olarak ele alınmaz. Yazım hatalarını ve mevcut olmayan bir
            modül tarafından gerçeklenmiş yönergeleri kapsar.
      • 
          
    • Nonfatal=All ile yukarıdakilerin ikisi de
            ölümcül olarak ele alınmaz.
      • 
        
    
        
    Geçerli bir yönergedeki yazım hatalarının hala dahili bir sunucu
          hatasına sebep olacağına dikkat ediniz.
    
        
    Güvenlik
    
          Ölümcül olmayan hatalar .htaccess
          kullanıcıları için güvenlikle ilgili sorunlara yol açabilir. Örneğin
          AllowOverride AuthConfig'e izin vermezse kullanıcıların
          siteye erişimini kısıtlayan yapılandırma iptal edilmiş olur.
      
    
      
    

      
    Options[=seçenek,...]
    

      
    Dizinlere özgü özellikleri denetleyen
        Options ve
        XBitHack yönergelerinin
        kullanımına izin verilir. Options komutunda belirtilecek seçenekler
        bir eşit işaretinden sonra aralarına sadece virgül konarak,
        fakat virgülden sonra boşluk bırakmadan belirtilebilir.

      
    Options'ın örtük iptali
    
      
    .htaccess dosyalarında kullanılabilen
        seçenek listesi bu yönergeyle sınırlanabilirse de herhangi bir
        Options yönergesine izin
        verildiği sürece miras alınmış diğer seçenekler göreli olmayan
        sözdizimi kullanılarak iptal edilebilir. Başka bir deyişle, bu
        mekanizma diğerlerinin değerlerini korumasına izin verirken belli bir
        seçeneği değerini korumaya zorlayamaz.
      
    

      
    
      AllowOverride Options=Indexes,MultiViews
      
    
      
    
    
    

    
    Örnek:
    

    
    AllowOverride AuthConfig Indexes
    


    
    Bu örnekte AuthConfig ve Indexes grubundaki
      yönergeler bir dahili sunucu hatasına yol açmayacaktır.
    

    
    Güvenlik ve başarımı arttırmak için
      <Directory "/">
      bloğu içinde AllowOverride yönergesine None
      dışında bir değer atamayın. Böyle yapmak yerine bir .htaccess
      dosyası yerleştirmeyi düşündüğünüz dizine ait bir
      <Directory> bloğu olması daha iyidir.

    Sunucu bir .htaccess dosyası (AccessFileName tarafından belirtildiği gibi)
      bulduğunda önceki yapılandırma yönergelerini geçersiz kılabilen bu
      dosyada hangi yönergelerin bildirildiğini bilmek ister.
    

    
    Sadece <Directory> bölümlerinde kullanılabilir
    
      AllowOverrideList sadece <Directory> bölümlerinde düzenli
      ifadeler olmaksızın belirtilmişse kullanılabilir; <Location>, <DirectoryMatch> veya <Files> bölümlerinde değil.
    
    

    
    Bu yönergeye ve AllowOverride
      yönergesine None atanmışsa
      .htaccess dosyaları tamamen yoksayılır. Bu
      durumda sunucu dosya sistemindeki .htaccess dosyalarını
      okumaya bile çalışmayacaktır.
    

    
    Örnek:
    

    
    AllowOverride None
AllowOverrideList Redirect RedirectMatch
    


    
    Yukarıdaki örnekte sadece Redirect ve
      RedirectMatch yönergelerine izin verilmektedir. Tüm
      diğerleri dahili bir sunucu hatasına sebep olacaktır.
    

    
    Örnek:
    

    
    AllowOverride AuthConfig
AllowOverrideList CookieTracking CookieName
    


    
    Yukarıdaki örnekte AllowOverride
       yönergesi AuthConfig yönerge grubuna izin
      verirken AllowOverrideList yönergesi
      FileInfo yönerge grubundan yalnız iki yönergeye izin
      vermektedir. Tüm diğerleri dahili bir sunucu hatasına sebep
      olacaktır.

    Bu yönerge Apache httpd’nin CGI bekitlerini çalıştırmak için
      kullanacağı yorumlayıcıyı nasıl bulacağını denetlemek için kullanılır.
      Örneğin, CGIMapExtension sys:\foo.nlm .foo satırı
      .foo uzantılı CGI betik dosyalarının FOO yorumlayıcıya

    Uyumluluk: Apache HTTP Sunucusunun 2.4.13 ve sonraki sürümlerinde kullanılabilmektedir
    

    
    
    CGIPassAuth yönergesi, HTTP Temel kimlik
      doğrulamasını gerçekleştiren betikler için gereken
      Authorization gibi HTTP yetkilendirme başlıklarına
      betiklerin erişebilmesini sağlar. Normalde bu HTTP başlıkları
      betiklerden gizli olup sunucuda HTTP Temel kimlik kanıtlaması etkin
      kılındığında sunucuya erişmekte kullanılan kullanıcı kimliklerinin ve
      parolalarının betikler tarafından görülmemesini mümkün kılar. Bu yönerge,
      HTTP Temel kimlik kanıtlamasını betiklerin gerçekleştirmesini sağlamak
      için kullanılmalıdır.
    

    
    Apache HTTP Sunucusunun önceki sürümlerinde derleme sırasında
      kullanılabilen SECURITY_HOLE_PASS_AUTHORIZATION sabitinin
      yerine bu yönerge kullanılabilir.
    

    
    Bu ayarlama mod_cgi, mod_cgid,
      mod_proxy_fcgi, mod_proxy_scgi ve
      benzerleri gibi ap_add_common_vars() kullanan modüller
      tarafından kabul görür. Özellikle, isteği alışılmış tarzda işleme
      sokmayıp bu arayüzü kullanan modülleri etkiler. Ayrıca,
      ap_add_common_vars() kullanmayan üçüncü parti modüller de
      bu ayarlamayı kullanmayı tercih edebilir.

    Durum:Çekirdek
    

    Modül:core
    

    
    
    Bu yönerge RFC2616 ve RFC1864’te tanımlandığı gibi
      Content-MD5 üretimini etkin kılar.
    

    
    MD5, verideki herhangi bir değişikliğin ileti özetinin değişmesi
      olarak yansıması nedeniyle yüksek derecede itimat sağlayan keyfi
      uzunlukta bir "ileti özeti" (bazen "parmakizi" dendiği de olur)
      hesaplama algoritmasıdır.
    

    
    Content-MD5 başlığı öğe gövdesinin iki uç arasında ileti
      bütünlük sınamasının yapılabilmesini sağlar. Bir istemci veya vekil
      aktarılan öğe gövdesinde rastlantısal bir değişiklik olup olmadığını
      saptamak için bu başlığın doğruluğunu sınayabilir. Başlık örneği:
    

    
    
      Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
    
    

    
    Her istekte ileti özeti hesaplanacağından (değerler saklanmaz), bu
      yönergenin sunucunuzda başarım sorunlarına yol açacağına dikkat
      ediniz.
    

    
    Content-MD5, herhangi bir modül değil, sadece
      core modülü tarafından sunulan belgeler için
      gönderilir. Örneğin, SSI belgeleri CGI betikleri tarafından
      çıktılanırlar ve bayt seviyesinden çıktılar bu başlığa sahip
      olmazlar.

      sarmalamakta kullanılır. Bir dizin bağlamında kullanılabilecek her
      yönergeye izin verilir. dizin-yolu bir dizinin tam yolu
      olabileceği gibi Unix kabuk tarzı bir dosya ismi eşleştirme kalıbı da
      olabilir. Kalıp dizgesinde, ? herhangi bir tek karakterle,
      * herhangi bir karakter dizisiyle eşleşir. Ayrıca
      [] karakter aralıkları da kullanılabilir. ‘/’ karakteri
      ile hiçbir kalıp karakteri eşleşmez, bu bakımdan <Directory
      "/*/public_html"> ile /home/user/public_html
      değil, ama <Directory "/home/*/public_html">
      eşleşecektir. Örnek:
    

    
    <Directory "/usr/local/httpd/htdocs">
  Options Indexes FollowSymLinks
</Directory>
    


    
    Dizin yollarında isterseniz önceleme kullanabilirsiniz, ancak eğer yol
      bazı boşluklar içeriyorsa mutlaka kullanmanız gerekir. Bir boşluk aksi
      belirtilmedikçe bir ifadenin sonunu belirlediğinden bu gereklidir.
    

    
    
      
    dizin-yolu argümanlarını belirtirken dikkatli
        olmalısınız: Apache httpd’nin dosyalara erişmekte kullandığı dosya
        sistemi yolu ile bire bir eşleşmelidir. Belli bir
        <Directory> dizinine uygulanan yönergeler, aynı
        dizine farklı bir yoldan, örneğin başka bir sembolik bağ üzerinden
        erişilen dosyalara uygulanmayacaktır.
    
    
    

    
    ~ karakterine ek olarak düzenli
      ifadeler de kullanılabilir. Örnek:
    

    
    <Directory ~ "^/www/[0-9]{3}">

</Directory>
    


    
    yönergesi /www/ içindeki üç rakamdan oluşan dizinlerle
      eşleşecektir.
    

    
    Eğer çok sayıda (düzenli ifade olmayan) <Directory> bölümü, bir dosyayı içeren bir
      dizinle veya üst dizinlerinden biri ile eşleşiyorsa, uygulama en kısa
      eşleşmedeki yönergelerden başlayarak .htaccess dosyalarındaki yönergelere kadar
      genişletilir. Örneğin,
    

    
    <Directory "/">
  AllowOverride None
</Directory>

<Directory "/home">
  AllowOverride FileInfo
</Directory>
    


    
    bölümleri ile /home/web/dir/doc.html belgesine erişirken
      şu aşamalardan geçilir:
    

    
      
      
    • AllowOverride None yönergesi uygulanır
        (.htaccess dosyaları iptal edilir).
      • 

      
    • AllowOverride FileInfo yönergesi uygulanır
        (/home dizini için).
      •

      2.3.9 öncesinde, bu yönerge örtük olarak (<Directory> gibi) alt dizinlere de uygulanırdı
      ve satır sonu simgesi ($) ile eşleşemezdi. 2.3.9 ve sonrasında, sadece
      ifade ile eşleşen dizinler sarmalanan yönerge grubundan etkilenmektedir.
    
    

    
    Sondaki bölü çizgileri
    
      Bu yönerge bir bölü çizgisi ile sonlanan veya sonlanmayan dizinler için
      yapılan isteklere uygulanır, dolayısıyla satır sonuna ($) çıpalanmış
      ifadeler dikkatli yazılmalıdır.
    
    

    
    2.4.8 itibariyle, isimli gruplar ve geriye başvurular elde edilmekte
      olup ilgili isim büyük harfe çevrildikren sonra "MATCH_" ile
      öncelendikten sonra ortama yazılmaktadır. Böylece yol elemanlarına
      mod_rewrite gibi modüllerden veya düzenli ifadelerden başvurmak mümkün
      kılınmıştır. Karışıklığı önlemek için, numaralı (isimsiz) geriye
      başvurular yoksayılmaktadır. Bunların yerine isimli geriye başvurular
      kullanılmalıdır.

    Durum:Çekirdek
    

    Modül:core
    

    Uyumluluk:none değeri Apache 2.2.7 ve sonrasında mevcuttur.

    

    
    
    Bu yönerge, sunucunun teslimat sırasında gerektiği takdirde bir dosya
      içeriğinin okunması için bellek eşleme kullanıp kullanmayacağını
      belirler. Öntanımlı olarak, bir isteğin yerine getirilmesi,
      mod_include kullanarak sunucu tarafından çözümlenen
      bir dosyanın teslimatı sırasında olduğu gibi, bir dosya içindeki veriye
      erişilmesini gerektirdiğinde Apache httpd, işletim sistemi tarafından
      desteklendiği takdirde dosyayı belleğe eşler.
    

    
    Böyle bellek eşleme kimi zaman başarım artışını beraberinde getirirse
      de bazen sorunlardan kaçınmak için bellek eşlemeyi kapatmak daha iyi
      sonuç verir:
    

    
      
    
    • Bazı çok işlemcili sistemlerde bellek eşleme
      httpd’nin başarımını düşürebilmektedir.
      • 
    
    • httpd bellek eşlemli çalışırken bir dosyanın
      silinmesi veya boyutunun küçültülmesi httpd'nin
      parçalama arızası vererek çökmesine yol açabilir.
      • 
    
    

    
    Bu tür sorunlardan dolayı zarar görülebilecek sunucu
      yapılandırmalarında dosya teslimatında bellek eşlemlerinin kullanımını
      şu şekilde iptal etmeniz gerekir:
    

    
    EnableMMAP Off
    


    
    Bu özellik, sadece NFS dosya sistemi üzerinde sunulan dosyaları
      kapsamak üzere şu şekilde kolayca kapatılabilir:
    

    
    <Directory "/nfs-dosyaları-yolu">

    Modül:core
    

    Uyumluluk:Öntanımlı değer 2.3.9 sürümünde Off olarak değişti.
    

    
    
    Bu yönerge, dosya içeriğinin istemciye teslimi için
      httpd’nin çekirdeğin dosya gönderme desteğini
      kullanıp kullanmayacağını belirler. Öntanımlı olarak, bir isteğin
      yerine getirilmesi, bir durağan dosyanın teslimatı sırasında olduğu
      gibi, bir dosya içindeki veriye erişilmesini gerektirmediği takdirde
      Apache httpd, işletim sistemi tarafından destekleniyorsa dosyayı
      istemciye teslim etmek için çekirdeğin dosya gönderme özelliğini
      kullanır.
    

    
    Çekirdeğin dosya gönderme mekanizması, okuma, gönderme ve tampon
      ayırma işlemlerini ayrı ayrı yapmaktan kaçınır. Fakat bazı
      platformlarda veya bazı dosya sistemlerinde aşağıda belirtilen işlemsel
      sorunlardan kaçınmak için bu özelliği iptal etmek daha iyidir:
    

    
      
    
    • Bazı platformlar,  derleme sistemince saptanamayan bozuk bir dosya
      gönderme desteğine sahiptir; özellikle eğer derleme işlemi dosya
      gönderme desteğinde sorun olmayan bir makinede yapılıp çalıştırılabilir
      dosyaların sorunlu makineye kurulduğu durumda bu saptama
      yapılamayacaktır.
      • 
    
    • Linux’ta IPv6 kullanırken dosya gönderme desteği bazı ağ
      kartlarındaki TCP toplama sağlaması aktarım hatasını tetikler.
      • 
    
    • Itanium üzerinde çalışan Linux’ta dosya gönderme desteği
      (sendfile) 2GB’tan büyük dosyalarla çalışamamaktadır.
      • 
    
    • DocumentRoot ağ dosya sistemi
      (NFS, SMB, CIFS, FUSE gibi) üzerinde olduğu durumda çekirdek ağ
      dosyalarını kendi arabelleği üzerinden sunamayabilir.
      • 
    
    

    
    Bu sorunlardan muzdarip sunucu yapılandırmaları için bu özelliği şöyle
      etkin kılabilirsiniz:
    

    
    EnableSendfile On
    


    
    Bu özellik, sadece bir ağ dosya sistemi üzerinde sunulan
      dosyaları kapsamak üzere şu şekilde kolayca kapatılabilir:
    

    
    <Directory "/nfs-dosyaları-yolu">
  EnableSendfile Off
</Directory>
    



    EnableSendfile yönergesinin .htaccess ve
      diziniçi yapılandırmalarının mod_cache_disk tarafından
      desteklenmediğini lütfen aklınızdan çıkarmayın.
      EnableSendfile yönergesinin sadece küresel
      tanımları hesaba katılır.

    Modül:core
    

    
    
    Bir sorun çıktığında veya hata oluştuğunda Apache httpd şu dört
      işlemden birini yapacak şekilde yapılandırılabilir:
    

    
      
      
    1. Yerleşik bir hata iletisi çıktılanır.
      2. 

      
    2. Özel bir ileti çıktılanır.
      3. 

      
    3. Sorunu/hatayı işleyecek yerel bir URL-yoluna dahili bir
        yönlendirme yapılır.
      4. 

      
    4. Sorunu/hatayı işleyecek harici bir URL-yoluna
        yönlendirme yapılır.
      5. 
    
    

    
    İlk seçenek öntanımlıdır. Diğer üç seçenek
      ErrorDocument yönergesinin argümanları (hata
      kodundan sonra bir URL veya hata iletisi) ile belirtilir. Apache httpd
      bazı durumlarda sorun/hata ile ilgili ek bilgi verecektir.
    

    
    2.4.13 itibariyle, özdevinimli dizgeler ve URLler üretmek için yönerge
      içinde ifade sözdizimi kullanılabilir.
    

    
    URL’ler yerel yollarda (DocumentRoot’a göre) bir bölü çizgisi (/) ile
      başlatılabileceği gibi istemci tarafından çözümlenecek tam bir URL
      şeklinde de belirtilebilir. Bunlar yerine, tarayıcıda gösterilmek üzere
      bir ileti de belirtilebilir. Örnekler:
    

    
    ErrorDocument 500 http://example.com/cgi-bin/server-error.cgi
ErrorDocument 404 /errors/bad_urls.php
ErrorDocument 401 /subscription_info.html
ErrorDocument 403 "Kusura bakmayın, bugün hizmet veremiyoruz."
ErrorDocument 403 /errors/forbidden.pl?referrer=%{escape:%{HTTP_REFERER}}
    


    
    Bunlardan başka, Apache httpd’nin kendi hata iletilerinin kullanılacağı
      özel default değeri ile belirtilebilir. Normal şartlar
      altında gerekmese de, bir şey belirtilmediği takdirde mevcut bir
      ErrorDocument yönergesini miras alan
      yapılandırmalarda Apache httpd’nin kendi hata iletilerinin kullanımı
      default değeri açıkça belirtilerek örnekteki gibi
      zorlanabilir:
    

    
    ErrorDocument 404 /cgi-bin/bad_urls.pl

<Directory "/web/docs">
  ErrorDocument 404 default
</Directory>
    


    
    ErrorDocument yönergesinde bir uzak URL (önünde
      http bulunan bir yol) belirtildiğinde, belge aynı sunucuda
      olsa bile, Apache HTTP Sunucusunun istemciye belgeyi bulacağı yer için bir
      yönlendirme göndereceğine dikkat ediniz. Bunun bazı istenmeyen etkileri
      vardır; en önemlilerinden biri istemcinin hata kodu yerine bir
      yönlendirme durum kodu alacak olmasıdır. Bu, bir URL’nin geçerliliğini
      durum koduna göre saptayan istemciler veya robotlar için yanıltıcı
      olacaktır. Buna ek olarak, ErrorDocument 401 için bir uzak
      URL belirttiğiniz durumda istemci 401 durum kodunu almayacağı için
      kullanıcıdan parola isteğinde bulunamayacaktır. Bu bakımdan,
      ihtiyaç duyduğunuz takdirde, ErrorDocument 401
      yönergesine yerel bir belge belirtmelisiniz.
    

    
    Sunucunun ürettiği hata iletileri "çok kısa" olduğu takdirde,
      Microsoft Internet Explorer (MSIE) öntanımlı olarak bu hata iletilerini
      yoksayar ve bunun yerine kendi "kullanıcı dostu" hata iletilerini
      kullanır. "Çok kısa" eşiği duruma göre değişmekle birlikte, genellikle,
      hata iletileriniz 512 bayttan büyük olduğu takdirde MSIE kendi hata
      iletileri yerine sunucunun ürettiği hata iletilerini gösterecektir. Bu
      konuda daha fazla bilgiyi Q294807 kodlu Microsoft Knowledge Base makalesinde
      bulabilirsiniz.
    

    
    Çoğu yerleşik hata iletisi özel iletilerle değiştirilebilse de bazı
      durumlarda ErrorDocument ile ne
      belirtildiğine bakılmaksızın yerleşik hata iletileri kullanılır.
      Özellikle, bozuk bir istek saptandığında normal istek işleme hemen
      devre dışı bırakılır ve yerleşik hata iletisi döndürülür. Bu, hatalı
      istekler yaparak güvenlik sorunlarına yol açılmak istenmesi
      durumlarında gereklidir.
    

    
    mod_proxy kullanıyorsanız,
      ProxyErrorOverride yönergesini
      etkin kılmak isteyebilirsiniz, böylece asıl sunucular adına özel hata
      iletileri üretebilirsiniz. ProxyErrorOverride etkin
      kılınmak istenmezse, Apache httpd vekalet edilen içerik için özel hata
      belgeleri üretmeyecektir.

    Dosya adı yerine syslog kullanılırsa, sistem desteklediği
      takdirde günlük kaydı syslogd(8) üzerinden yürütülür. Öntanımlı olarak
      local7 syslog oluşumu kullanılır. Bunu
      syslog:oluşum sözdizimini kullanarak
      değiştirebilirsiniz. Buradaki oluşum
      syslog.conf(5) kılavuz sayfasında belirtilen oluşum isimlerinden biri
      olabilir. Oluşum aslında küreseldir ve sanal konaklardan bazılarında
      değiştirilmişse, belirtilen en son oluşum tüm sunucuyu
      etkileyecektir. etiket için de aynı kurallar
      uygulanır. Genellikle, öntanımlı etiket olarak Apache çalıştırılabilirinin
      ismi olan httpd kullanılır. Öntanımlı etiketi
      syslog::etiket sözdizimini kullanarak
      değiştirebilirsiniz 
    

    
    ErrorLog syslog:user
ErrorLog syslog:user:httpd.srv1
ErrorLog syslog::httpd.srv2
    


    
    GÜVENLİK: Günlük dosyalarının saklandığı dizin, sunucuyu başlatan
      kullanıcı dışındakiler tarafından yazılabilir olduğu takdirde
      güvenliğinizin nasıl tehlikeye gireceği güvenlik ipuçları
      belgesinde ayrıntılı olarak açıklanmıştır.
    
    
    Ek Bilgi
    
      
    Unix-dışı platformlarda dosya yolunu girerken, platform ters bölü
        çizgilerini desteklese bile normal bölü çizgileri kullanmaya özen
        göstermelisiniz. Genel olarak, dosya yollarını belirtirken
        yapılandırma dosyası boyunca normal bölü çizgisi kullanmak her zaman
        daha iyidir.

    ErrorLogFormat yönergesi, hata günlüğünde asıl
      hata iletisine ek olarak günlüklenecek ek bilgiyi belirtmek için
      kullanılabilir.
    

    
    #Basit örnek
ErrorLogFormat "[%t] [%l] [pid %P] %F: %E: [client %a] %M"
    


    
    İlk değiştirge olarak connection veya request
      belirtilmesi ek biçemlerin belirtilebilmesini sağlar. Böylece, belli bir
      bağlantı ya da istek için ilk ileti günlüklendiğinde ek bilgininde
      günlüklenmesi sağlanır. Bu ek bilgi sadece bağlantı/istek başına bir
      kere günlüklenir. herhangi bir günlük iletisine sebep olmadan işlenmişse
      ek bilgi de günlüklenmez.
    

    
    Bu, bazı biçem dizgesi öğeleri çıktı üretmediğinde olur. Örneğin,
      Referer başlığı sadece günlük iletisi bir istekle
      ilişkilendirilmişse mevcuttur ve hata iletisi Referer
      başlığı istemcide okunduğu anda oluşur. Eğer bir çıktı üretilmezse,
      öntanımlı davranış önceki boşluk karakterinden sonraki boşluk
      karakterine kadar herşeyi silmektir. Yani, günlük satırı örtük olarak
      boşluklarla ayrılmış alanlara bölünür. Bir biçem dizgesi öğesi çıktı
      üretmezse alanın tamamı çıktılanmaz. Örneğin, [%t] [%l] [%a]
      %M  günlük biçeminde uzak adres %a
      kullanılamazsa sarmalayıcı köşeli ayraçlar da günlüklenmeyecektir.
      Boşluk karakterleri ters bölülerle öncelenerek bir alanı sınırlaması
      önlenebilir. '% ' (yüzde boşluk) çifti sıfır genişlikte bir alan
      ayracı olup herhangi bir çıktı üretmez.
    

    
    Yukarıdaki davranış, biçem dizgesi öğesine değiştirciler eklenerek
      değiştirilebilir.  - (tire) değiştircisi ilgili öğe bir
      çıktı üretmediğinde tire iminin günlüklenmesine sebep olur.
      Bağlantı/istek başına bir kere biçemlerinde + (artı)
      değiştircisini de kullanmak mümkündür.Artı değiştiricili bir öğe
      herhangi bir çıktı üretmezse satırın tamamı günlüklenmez.
    

    
    Bir biçem öğesine günlük önem derecesi atamak için değiştirici
      olarak bir sayı kullanılabilir. Bu öğenin günlüklenebilmesi için günlük
      iletisinin önem derecesinin belirtilen günlük önem derecesinden
      daha yüksek olmaması gerekir. Sayı 1'den (alarm) 4'e (uyarı) ve 7'den
      (hata ayıklama) 15'e (trace8) kadar olabilir.
    

    
    Örneğin, Referer istek başlığını günlükleyen
      %{Referer}i dizgeciğine değiştirciler eklendiğinde neler
      olduğunu burada görebilirsiniz:
    

    
    Değiştirlen DizgecikAnlamı
    

    
    %-{Referer}i
    Referer atanmamışsa bir - günüklenir.
    
    

    
    %+{Referer}i
    Referer atanmamışsa satırın tamamı çıktılanmaz.
    
    

    
    %4{Referer}i
    Sadece hata iletisinin önemi 4'ten yüksek olduğu durumda
      Referer günlüklenir.
    
    

    

    
    Bazı biçem dizfesi öğeleri ayraç içine alınmış ek değiştirgeler kabul
      eder.

    FileETag yönergesi, belge bir duruk dosyaya
      dayandığı takdirde ETag (Entity Tag - öğe etiketi
      kısaltması) yanıt başlığı alanını oluşturmakta kullanılacak dosya
      özniteliklerini yapılandırır. (ETag değeri, ağ band
      genişliğinden kazanmak için arabellek yönetiminde kullanılır.)
      FileETagyönergesi ne kullanılması gerektiğini
      belirleyebilmenizi sağlar. Değer olarak belirtilebilecek anahtar
      sözcükler şunlardır:
    

    
    
     
    INode
    
     
    Dosyanın düğüm numarası hesaba katılır.
    
     
    MTime
    
     
    Dosyanın son değişiklik tarih ve saati dahil edilir.
    
     
    Size
    
     
    Dosyanın bayt cinsinden uzunluğu dahil edilir.
    
     
    All
    
     
    Olası tüm alanlar kullanılır. Bu şuna eşdeğerdir:
         
    FileETag INode MTime Size
    

    
     
    Digest
    
     
    Bir belge dosya tabanlı ise ETag alanı dosyanın özeti
      alınarak hesaplanır.
    
     
    None
    
     
    Bir belge dosyasıyla sunulsa bile yanıta hiçbir ETag
      alanı dahil edilmez.
    
    
    

    
    Öntanımlı ayarları miras alıp bunların kapsamını genişletmek/daraltmak
      için INode, MTime, Size ve
      Digest anahtar sözcüklerinin önüne + veya
      - imi konabilir. Bu imlerin bulunmadığı bir anahtar
      sözcüğün varlığı halinde hiçbir değer miras alınmaz.
    

    
    Eğer bir dizinin yapılandırması
      FileETag INode MTime Size ve alt dizini
      FileETag -INode içeriyorsa bu alt dizinin (ve bir
      geçersizleştirme olmadığı takdirde onun alt dizinlerinin) ayarları
      FileETag MTime Size yapılandırmasına eşdeğer
      olacaktır.
    
    
    Sunucu Taraflı İçerik
    
      Gömülü SSI yönergeleri ile bir duruk dosyanın FileETag,
      MTime, Size ve Digest değerleri
      değişmeksizin yanıt öğesi değişebileceğinden mod_include
      tarafından çözümlenen yanıtlar için bir ETag üretilmez.

      yapılandırmalarda SetHandler veya
      AddHandler kullanımından
      kaçınılmalıdır.

    Açıklama:İstemci IP adresleri üzerinde DNS sorgularını etkin kılar.

    

    Sözdizimi:HostnameLookups On|Off|Double
    

    Öntanımlı:HostnameLookups Off
    

    Bağlam:sunucu geneli, sanal konak, dizin
    

    Durum:Çekirdek
    

    Modül:core
    

    
    
    Bu yönerge oturum açabilecek konak isimlerini tespit edebilmek için
      DNS sorgularını etkin kılar (ve sonuç REMOTE_HOST’ta
      belirtilerek CGI/SSI’lere aktarılır). Double değeri
      sorgunun çift yönlü yapılacağını belirtir. Yani, bir tersine sorgunun
      ardından bir normal sorgu yapılır. Normal sorguda elde edilen IP
      adreslerinden birinin istek yapan IP adresi ile eşleşmesi gerekir.
      ("tcpwrappers" terminolojisinde buna PARANOID adı
      verilir.)
    

    
    Konak ismine göre erişimi denetlemek için
      mod_authz_host kullanıldığında, nasıl bir ayar
      yapıldığına bakılmaksızın, çift yönlü sorgulama yapılır. Bu güvenlik
      için gereklidir. Bunun dışında açıkça HostnameLookups
      Double belirtilmedikçe genellikle çift yönlü sorgulama yapılmaz.
      Örneğin, sadece  HostnameLookups On belirtilmiş ve konak
      ismi kısıtlamalarıyla korunmuş bir nesne için bir istek yapılmışsa çift
      yönlü sorgunun başarısına bakılmaksızın CGI’lere
      REMOTE_HOST olarak tek yönlü sorgu sonucu aktarılır.
    

    
    Gerçekte ters yönlü sorguya gerek duyulmayan sitelerde ağ trafiğini
      yormamak için Off, öntanımlı değerdir. Ayrıca, son
      kullanıcıların DNS sorguları nedeniyle gereksiz yere bir beklemeye
      maruz kalmaması için de bu daha iyidir. Yükü zaten ağır olan sitelerde,
      DNS sorgularının görece uzun zaman alması nedeniyle bu yönergenin
      değeri Off olarak bırakılmalıdır. Öntanımlı olarak kurulum
      dizininizin bin alt dizinine kurulan
      logresolve uygulaması kullanılarak oturum açan IP
      adresleri için isim sorguları çevrim dışıyken yapılabilir.
    

    
    Son olarak, konak ismine dayalı
      Require yönergelerine sahipseniz konak ismi araması
      HostnameLookups ayarına bakılmaksızın
      gerçekleştirilecektir.

    HttpProtocolOptions Yönergesi
    

    

    Açıklama:HTTP İstek İletilerindeki sınırlamalarda değişiklik yapar
    

    Sözdizimi:HttpProtocolOptions [Strict|Unsafe] [RegisteredMethods|LenientMethods]
 [Allow0.9|Require1.0]
    

    Öntanımlı:HttpProtocolOptions Strict LenientMethods Allow0.9
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Çekirdek
    

    Modül:core
    

    Uyumluluk:2.2.32 veya 2.4.24 ve sonrası
    

    
    
    Bu yönerge HTTP istek satırına
      (RFC 7230 §3.1.1) ve the HTTP istek başlığı alanlarına
      (RFC 7230 §3.2) uygulanmış kuralları öntanımlı olarak veya
      Strict seçeneği kullanılarak  değiştirir. Eski modüller,
      uygulamalar veya kullanımı önerilmeyen özel istemciler için eski davranışlara
      dönmeyi sağlamak üzere Unsafe seçeneği eklenmiştir.
    

    
    Bu kurallar istek işlenmeden önce uygulanır. Dolayısıyla yönerge, IP/port
      arabirimine göre ana bölümde veya öntanımlı (ilk) eşleşen sanal konak
      bölümünde yapılandırılmalıdır.
    

    
    Bu yönergeye aşağıdaki parametrelerden seçilen üç tanesi uygulanabilir.
      Belirtilmeyenlerin yerine öntanımlılar uygulanır.
    

    
    
      
    Strict|Unsafe
    
      
    
        
    Bu yönerge devreye girmeden önce, Apache HTTP Sunucusunun istek iletisi
        ayrıştırıcıları protokolle uyumlu olmayan bir dizi girdi şekline
        toleranslıydı. RFC 7230 §9.4 İstek bölme ve
        §9.5 Yanıt kaçırma çağrıları uyumsuz istek iletilerinin
        kabulündeki olası risklerden yalnızca iki tanesidir.
        RFC 7230
        §3.5 "İleti Ayrıştırma Sağlamlığı" belirsiz boşlukların kabul ve
        istek iletisi biçimleme risklerini tanımlar. Bu yönergenin devreye
        girmesini takiben belirtimin tüm imla kurallarına öntanımlı
        Strict işlem kipi ve 3.5 bölümünde tavsiye edilen hoşgörüsüz
        boşluk uygulanır ve esnekliğe müsamaha edilmez.
    

        
    Unsafe için güvenlik riskleri
    
          
    Kullanıcılar, özellikle dışa bakan, herkes tarafından erişilebilen
          sunucu konuşlandırmalarında  Unsafe işlem kipine geçiş
          yapmaya karşı kesinlikle uyarılır. Eğer bir arayüz hataları izlemek
          veya bir intranette çalışan özel hizmet tüketicileri için gerekliyse,
          kullanıcılar, sadece, dahili özel ağlarına hizmet etmek üzere
          yapılandırılmış özel bir sanal konak üzerinde Unsafe işlem
          kipine geçiş yapmalıdır.
    
        
    

        
    Strict kipte HTTP 400 ile sonuçlanan bir istek örneği
    
          
          # Eksik CRLF
    
          GET / HTTP/1.0\n\n
        
    
        
    Komut satırı araçları ve CRLF
    
          
    Bazı araçların CRLF kullanmaya zorlanması gerekir, aksi takdirde httpd
          yukarıdaki örnekte belirtildiği gibi bir HTTP 400 yanıtı ile döner.
          Örneğin,  OpenSSL s_client düzgün çalışmak için -crlf
          değiştirgesine ihtiyaç duyar.
    
          
    CRLF yokluğu gibi durumları saptamak için HTTP isteğini görünümlemek
          isterseniz DumpIOInput
          yönergesi yardımcı olabilir.
    
        
    
      
    
      
    RegisteredMethods|LenientMethods
    
      
    
        
    RFC 7231
        §4.1 "İstek Yöntemleri" "Genel Bakış" bölümlerinde bir istek
        satırında desteklenmeyen bir yöntem saptadığında özgün sunucuların bir
        hatayla yanıt vermesini gerekli görmüştür. LenientMethods
        seçeneği kullanıldığında olan zaten budur. RegisteredMethods
        seçeneğine geçiş yapmak isteyen yöneticiler
        RegisterHttpMethod yönergesini kullanarak standart
        olmayan yöntemleri belirlemelidir. Özellikle Unsafe seçeneğine
        geçiş yapılacaksa bu yol izlenmelidir.
    

        
    İleri Vekil Uyumluluğu
    
          
    Özgün sunucunun kullandığı yöntemleri vekil sunucu bilemeyeceği için
          ileri vekil konaklarda RegisteredMethods seçeneğine geçiş
          yapılmamalıdır.
    
        
    

        
    Example of a request leading to HTTP 501 with LenientMethods mode
    
          
          # Unknown HTTP method
    
          WOW / HTTP/1.0\r\n\r\n

    
          # Lowercase HTTP method
    
          get / HTTP/1.0\r\n\r\n
    
        
    
      
    
      
    Allow0.9|Require1.0
    
      
    
        
    RFC 2616
        §19.6 "Önceki Sürümlerle Uyumluluk" bölümünde HTTP sunucularının
        eski HTTP/0.9 isteklerini desteklemesi tavsiye edilmektedir. RFC 7230
        "HTTP/0.9 isteklerini destekleme beklentisi kaldırılmıştır." cümlesiyle
        bunu  geçersiz kılmış ve RFC 7230 Ek A bölümünde bununla ilgili yorumlar yer almıştır.
        Require1.0 seçeneği kullanıcıya öntanımlı
        Allow0.9 seçeneğinin davranışına verilen desteği kaldırma
        imkanını vermektedir.
    

        
    Require1.0 kipinde HTTP 400 ile sonuçlanan bir istek
          örneği
    
          
          # Desteklenmeyen HTTP sürümü
    
          GET /\r\n\r\n
        
    
      
    
    
    

    
    LogLevel debug seviyesiyle
      yapılandırılmış ErrorLog ile kaydedilmiş günlüklerin
      gözden geçirilmesi, böyle hatalı isteklerin kaynaklandıkları yerle birlikte
      belirlenmesine yardımcı olabilir. Kullanıcılar, beklenmedik bir şekilde
      reddedilmiş geçersiz istekleri bulmak için erişim günlüklerindeki 400
      yanıtlarına özellikle dikkat etmelidir.

      ismi ve dizin parçalarında kabuk tarzı (fnmatch()) dosya
      ismi kalıp karakterleri kullanılabilir. Ayrıca, eğer
      Include yönergesi bir dosya değil de bir dizin
      gösteriyorsa Apache httpd bu dizindeki ve alt dizinlerindeki bütün
      dosyaları okuyacaktır. Bunula birlikte, dizinin bir bütün olarak
      okutulması önerilmez, çünkü dizinde httpd programının
      çökmesine sebep olabilecek geçici dosyalar unutulabilir. Bunun yerine,
      belli bir şablona uyan dosyaları seçebilmek için, örneğin *.conf gibi
      dosya kalıplarının kullanılmasını öneriyoruz.
    

    
    Include yönergesi, bir dosya
      kalıbı ifadesi hiçbir dosyayla eşleşmezse bir hatayla
      başarısız  olacaktır. Eşleşmeyen dosya kalıbı ifadelerinin
      yoksayılması gerekiyorsa IncludeOptional yönergesi kullanılabilir.
    

    
    Dosya yolu mutlak bir dosya yolu olarak belirtilebileceği gibi
      ServerRoot dizinine göreli olarak
      da belirtilebilir.
    

    
    Örnekler:
    

    
    Include /usr/local/apache2/conf/ssl.conf
Include /usr/local/apache2/conf/vhosts/*.conf
    


    
    Veya dizinler ServerRoot dizinine
      göre belirtilebilir:
    

    
    Include conf/ssl.conf
Include conf/vhosts/*.conf
    


     
    Dosya kalıbı karakterleri yolun dizin ve dosya parçalarına
       yerleştirilebilir. conf/vhosts altında en azından bir
       *.conf içeren hiçbir alt dizin yoksa bu örnek başarısız
       olacaktır:
    

    
    Include conf/vhosts/*/*.conf
    


    
    Bunun yerine, dizin ve dosyaların eksikliği durumunda aşağıdaki komut
      sadece yoksayılır:
    

    
    IncludeOptional conf/vhosts/*/*.conf

    Keep-Alive yönergesi HTTP/1.0 protokolüne bir eklenti olup
      HTTP/1.1 protokolünün kalıcı bağlantı özelliği aynı TCP bağlantısı
      üzerinden çok sayıda isteğin gönderilmesini mümkün kılan uzun süreli HTTP
      oturumları açılmasını sağlar. Bunun, çok sayıda resim içeren HTML
      belgelerin yanıt zamanlarında bazı durumlarda %50’lik bir hızlanmayla
      sonuçlandığı gösterilmiştir. Kalıcı bağlantıları etkin kılmak için
      yönerge KeepAlive On şeklinde kullanılır.
    

    
    HTTP/1.0 istemcileri için kalıcı bağlantılar sadece bir istemci
      tarafından özellikle istendiği takdirde kullanılabilir. Ek olarak,
      HTTP/1.0 istemci kalıcı bağlantıları sadece içerik uzunluğu baştan
      bilindiği zaman kullanılabilir. Bu, CGI çıktısı, SSI sayfaları ve
      sunucunun ürettiği dizin listeleri gibi genellikle HTTP/1.0 istemcilere
      kalıcı bağlantılar kullanmayan devingen içeriklere uygulanır. HTTP/1.1
      istemciler için kalıcı bağlantılar aksi belirtilmedikçe öntanımlıdır.
      İstemci istediği takdirde, uzunluğu bilinmeyen içerik kalıcı bağlantılar
      üzerinden gönderilirken parçalı kodlama kullanılacaktır.
    

    
    Bir istemci kalıcı bağlantı kullandığı takdirde, bağlantı üzerinden kaç
      istek gönderilirse gönderilsin,
      MaxConnectionsPerChild
      yönergesi bakımından tek bir istek olarak değerlendirilir.

    <Limit> Yönergesi

    Modül:core
    

    
    
    Erişim denetleyicileri normalde tüm erişim yöntemleri
      için etkindir ve olağan olanı da budur. Genel durum olarak,
      erişim denetim yönergeleri bir <Limit> bölümüne
      yerleştirilmemelidir.
    

    
    <Limit> bölümünün amacı, erişim
      denetleyicilerinin etkilerini belli HTTP yöntemleri için sınırlamaktır.
      <Limit> bölümü içinde listelenen
      erişim sınırlamaları, kalan tüm diğer yöntemler için etkisiz
      olacaktır. Aşağıdaki örnekte, erişim sınırlaması
      POST, PUT ve DELETE yöntemleri
      için uygulanmakta, diğer tüm yöntemler korumasız bırakılmaktadır:
    

    
    <Limit POST PUT DELETE>
  Require valid-user
</Limit>
    


    
    Birden fazla bölümde kullanılabilecek yöntem isimleri: GET,
      POST, PUT, DELETE,
      CONNECT, OPTIONS,
      PATCH, PROPFIND, PROPPATCH,
      MKCOL, COPY, MOVE,
      LOCK ve UNLOCK. Yöntem isimleri harf
      büyüklüğüne duyarlıdır. GET yöntemi sınırlanırsa
      HEAD istekleri de sınırlanmış olur. TRACE
      yöntemi sınırlanamaz (bkz, TraceEnable).
    

    
    Erişimi sınarlarken bir <Limit> bölümü yerine daima bir <LimitExcept> bölümünü tercih
      etmelisiniz, çünkü <LimitExcept> bölümü belirtilen yöntemler dışında kalanlara
      erişim koruması sağlar.
    

    
    <Limit> ve
    <LimitExcept>
    yönergeleri iç içe olabilirler. Bu durumda, başarılı her
    <Limit> veya <LimitExcept> seviyesi, erişim
    denetimlerinin uygulanacağı yöntemlerle sınırlı kalmalıdır.
    

    
    <Limit> veya
    <LimitExcept> yönergelerini
    Require yönergesi ile
    birlikte kullanılırken, ilk Require yönergesinin bir başka Require yönergesinin varlığından
    bağımsız olarak isteği başarıyla yetkilendirdiğine dikkat ediniz.
    

    
    Örneğin, aşağıdaki yapılandırmayı ele alalım; tüm kullanıcılar
    POST istekleri için yetkilendirilecek ve tüm durumlarda
    Require group editors yönergesi yoksayılacaktır:
    

    
    <LimitExcept GET>
  Require valid-user
</LimitExcept>
<Limit POST>
  Require group editors
</Limit>

      bütün yöntemler için erişimi kısıtlamakta kullanılabilir. Daha ayrıntılı
      bilgi edinmek için <Limit> yönergesinin açıklamasına bakınız.

    Örneğin, özgün istekleri dahili olarak bir CGI betiğine yönlendiren
      Action yönergesi
      kullanıldığında bir dahili yönlendirme oluşur. İstek içi istekler ise
      bazı URI’ler için istek yapıldığında ne olacağını bulmak için Apache
      httpd’nin kullandığı bir mekanizmadır. Örneğin,
      mod_dir, DirectoryIndex yönergesinde listelenen dosyalara bakmak
      için istek içi istekler kullanır.
    

    
    LimitInternalRecursion yönergesi sunucunun dahili
      yönlendirmeler ve istek içi isteklerin oluşturduğu döngülerden dolayı
      çökmemesini sağlar. Böyle döngüler genellikle yanlış yapılandırma sonucu
      ortaya çıkarlar.
    

    
    Yönerge her istek için değerlendirmeye alınacak iki farklı sınırlama
      için kullanılabilir. İlk sayı ardarda gelebilen dahili
      yönlendirmelerin azami sayısını, ikinci sayı ise istek içi
      isteklerin ne kadar iç içe olabileceğini belirler. Tek bir
      sayı belirtilirse iki sınırlama için de aynı değer
      kullanılır.

    Bu yönerge, bir istek gövdesinde izin verilen bayt sayısını 0 (sınırsız
      anlamında) ile 2147483647 (2GB) arasında sınırlamak için kullanılır.
      Vekil isteklerinin snırlı uygulanabilirliği için aşağıdaki nota
      bakınız.
    

    
    LimitRequestBody yönergesi kullanıcıya yönergenin
      kullanıldığı bağlam (sunucu, belli bir dizin, belli bir dosya, belli bir
      yer) dahilinde bir HTTP istek iletisi gövdesinin izin verilen uzunluğu
      için bir sınır belirleme imkanı verir. Eğer istemcinin isteği bu sınırı
      aşarsa sunucu isteği sunmak yerine bir hata iletisi döndürecektir. Normal
      bir istek ileti gövdesinin uzunluğu büyük oranda özkaynağın doğasına ve
      bu özkaynak üzerinde izin verilen yöntemlere bağlıdır. CGI betikleri
      genellikle ileti gövdesini form bilgisini almak için kullanır.
      PUT yöntemi gerçeklenimleri, en azından, sunucunun o
      özkaynak için kabul etmek isteyeceği herhangi bir gösterim kadar büyük
      bir değer gerektirecektir.
    

    
    Bu yönerge, bazı hizmet reddi (DoS) saldırılarından kaçınmak için sunucu
      yöneticilerine, anormal istemci istekleri üzerinde daha iyi denetim
      imkanı sağlar.
    

    
    Eğer, örneğin, belli bir yere dosya yükleme izni verir ve buraya
      yüklenebilecek dosya boyutunu 100 kB ile sınırlamak isterseniz yönergeyi
      şöyle kullanabilirsiniz:

    LimitRequestFields yönergesi sunucu
      yöneticilerine bir HTTP isteğinde izin verilen istek başlık alanlarının
      sayısı üzerindeki sınırı değiştirebilme imkanı verir. Sunucu bu değerin,
      normal bir istemci isteğinin içerebileceği alan sayısından daha büyük
      olmasına ihtiyaç duyar. Bir istemci tarafından kullanılan istek başlık
      alanlarının sayısı nadiren 20’yi geçer, fakat bu farklı istemci
      gerçeklenimleri için değişiklik gösterir ve çoğunlukla kullanıcının
      tarayıcısını ayrıntılı içerik müzakeresini desteklemek için nasıl
      yapılandırdığıyla ilgilidir. İsteğe bağlı HTTP eklentileri çoğunlukla
      istek başlık alanları kullanılarak ifade edilir.
    

    
    Bu yönerge, bazı hizmet reddi (DoS) saldırılarından kaçınmak için sunucu
      yöneticilerine, anormal istemci istekleri üzerinde daha iyi denetim
      imkanı sağlar. Eğer normal istemciler sunucudan istekte bulunurken çok
      fazla başlık alanı gönderildiğine dair bir hata iletisi alırlarsa bu
      değerin arttırılması gerekir.

    <Location> ne zaman
      kullanılmalı
    

    
    <Location> yönergesini dosya sistemi
      dışındaki içeriğe çeşitli yönergeler uygulamak için kullanın. Dosya
      sisteminde bulunan içerik için <Directory> ve <Files> bölümlerini kullanın. Bunun istisnası,
      sunucunun tamamına bir yapılandırma uygulamak için kolay bir yol olan
      <Location "/">  kullanımıdır.
    
    
    

    
    Kaynağa yapılan (vekil olmayan) tüm istekler için eşleşecek URL,
      /yol/ şeklinde bir URL yolu olmalı; ne şema, ne konak ismi
      ne port ne de sorgu dizgesi içermelidir. Vekil istekleri için eşleşecek
      URL ise şema://sunucuadı/dosya-yolu şeklinde olmalı ve önek
      içermelidir.
    

    
    URL içinde dosya kalıp karakterleri kullanılabilir. Dosya kalıp
      karakterleri bulunan bir dizgede bulunan ? karakteri
      herhangi bir tek karakterle eşleşirken * karakteri herhangi
      bir karakter dizisi ile eşleşecektir. URL yolu içindeki / karakterleri
      ile hiçbir dosya kalıp karakteri eşleşmez.
    

    
    Ayrıca, ~ karakteri eşliğinde
      düzenli ifadeler de kullanılabilir.
      Örneğin,
    

    
    <Location ~ "/(ek|hususi)/veri">
    #...
</Location>
    


    
    yönergesi /ek/veri ve /hususi/veri alt
      dizgeleriyle eşleşecektir. <LocationMatch> yönergesi <Location> yönergesinin düzenli ifade sürümüne
      eşdeğer davranır ve bir çok yazı tipinde ~ karakterini
      - karakterinden ayırmak zor olduğu için tercih edilir.
    

    
    <Location> işlevselliği özellikle
      SetHandler yönergesi ile birlikte
      kullanışlı olur. Örneğin, durum isteklerini etkin kılmak ama sadece
      example.com’dan gelen isteklere izin vermek için şöyle bir
      uygulama yapabilirsiniz:
    

    
    <Location "/status">
  SetHandler server-status
  Require host example.com
</Location>
    


    
    / (bölü çizgisi) hakkında
    
      
    Bölü çizgisinin URL içinde bulunduğu yere bağlı olarak özel anlamları
        vardır. Dosya sistemindeki çok sayıda yanyana kullanımının tek bir bölü
        çizgisi olarak ele alındığı duruma alışkın olanlar olabilir (yani,
        /home///foo ile /home/foo aynıdır).
        MergeSlashes yönergesine OFF
        atanmışsa URL uzayında bunun böyle olması gerekli değildir.
        Eğer çok sayıda bölü çizgisinin birleştirilmeden yanyana belirtilmesi
        gerekiyorsa
        <LocationMatch>
        yönergesinde ve <Location>
        yönergesinin düzenli ifadeli kullanımında bunun açıkça belirtilmesi
        gerekir.
    

      
    Örneğin, <LocationMatch "^/abc"> yönergesi
        /abc ile eşleşecek ama //abc ile
        eşleşmeyecektir. <Location>
        yönergesinin düzenli ifade içermeyen kullanımındaki davranış vekil
        isteklerinde kullanılana benzer ve doğrudan kaynağa yapılan (vekil
        olmayan) isteklerde çok sayıda bölü çizgisi dolaylı olarak tek bir bölü
        çizgisiyle eşleşecektir. Örneğin, <Location
        "/abc/def"> belirtirseniz ve istek /abc//def
        şeklinde olursa bu ikisi eşleşir.

      yönergelerin etki alanını <Location> yönergesinin yaptığı gibi belirtilen URL’lerle

    # ...
</LocationMatch>
    


    
    yönergesi /ek/veri ve /hususi/veri alt

    Eğer hedef, /ek/veri içeren değil de
        /ek/veri ile başlayan bir URL ise düzenli ifadenin önüne
        ^ getirmek gerekir.

    2.4.8 itibariyle, isimli gruplar ve geriye başvurular elde edilmekte
      olup ilgili isim büyük harfe çevrildikren sonra "MATCH_" ile
      öncelendikten sonra ortama yazılmaktadır. Böylece yol elemanlarına
      mod_rewrite gibi modüllerden veya düzenli ifadelerden başvurmak mümkün
      kılınmıştır. Karışıklığı önlemek için, numaralı (isimsiz) geriye
      başvurular yoksayılmaktadır. Bunların yerine isimli geriye başvurular
      kullanılmalıdır.

    / (bölü çizgisi) hakkında
    
      
    Bölü çizgisi karakteri URL üzerinde göründüğü yere bağlı olarak
      farklı anlamlar içerir. İnsanlar, birden çok bitişik bölü çizgisinin sık
      sık tek bir bölü çizgisine daraltıldığı dosya sistemindeki davranışına
      alışkın olabilir (örn, /home///foo ile
      /home/foo aynıdır).
      MergeSlashes yönergesine OFF
      atanmışsa URL uzayında bunun böyle olması gerekli değildir.
      Eğer çok sayıda bölü çizgisinin birleştirilmeden yanyana belirtilmesi
      gerekiyorsa
      <LocationMatch>
      yönergesinde ve <Location>
      yönergesinin düzenli ifadeli kullanımında bunun açıkça belirtilmesi
      gerekir.
    

      
    Örneğin, <LocationMatch "^/abc"> ile
      /abc isteği eşleşirken //abc isteği
      eşleşmez. <Location> yönergesinin
      regex olmayan kullanımı vekil isteklerindeki gibi davranır. Fakat
      vekil harici işlemlerde <Location>
      yönergesinin regex olmayan kullanımında çok sayıda bölü çizgisi örtük
      olarak tek bölü çizgisiyle eşleşir. Örneğin,
      <Location "/abc/def"> belirtirseniz
      /abc//def isteği bu ifade ile eşleşecektir.

    En az crit seviyesinin kullanılması önerilir.
    

    
    Örnek:
    

    
    LogLevel notice
    



    
    Ek Bilgi
    
      
    Günlük iletileri normal bir dosyaya yazılırken notice
        seviyesinden iletiler engellenemez ve dolayısıyla daima raporlanırlar.
        Ancak, günlük kaydı syslog kullanılarak yapılıyorsa bu
        uygulanmaz.
    
    
    

    
    Bir modül ismi olmaksızın bir seviye belirtmek seviyeyi bu seviyedeki
      tüm modüller için sıfırlayacaktır. Bir seviyyi bir modül ismiyle
      birlikte belirtmek seviyeyi sadece bu modül için sıfırlayacaktır. Modül
      ismi olarak, modülün kaynak dosyası ismini, modül kimliği veya
      _module sonekli modül ismi belirtmek mümkündür.
      Yani, aşağıdaki üç belirtim eşdeğerdedir:
    

    
    LogLevel info ssl:warn
LogLevel info mod_ssl.c:warn
LogLevel info ssl_module:warn
    


    
    Ayrıca seviyeyi dizin bağlamında değiştirmek de mümkündür:
    

    
    LogLevel info
<Directory "/usr/local/apache/htdocs/app">
  LogLevel debug
</Directory>
    


    
    Dizin bağlamında günük seviyesi yapılandırması sadece istek
      çözümlendikten ve istek dizinle ilişkilendirildikten sonra günlüklenen
      iletileri etkiler. Bağlantı veya sunucu ile ilişkilendirilmemiş günlük
      iletileri etkilenmez.

    birleştirilmesini önlemek için, eskiden, MergeSlashes
    yönergesine OFF atanabiliyordu.
    

    
    OFF atanması durumunda, yapılandırma dosyasında, adresin yol
    bileşeni ile eşleşen düzenli ifadelerde
    (LocationMatch, RewriteRule,
    ...) ardışık bölü çizgilerinin hesaba katılması gerekir. Düzenli ifade
    içermeyen Location yönergeleri daima birleştirilmiş
    bölü çizgileri içeren bir URL'ye karşı çalışır ve çok sayıdaki bölü
    çizgileri arasında bir ayrım yapamaz.

    Bu yönerge HTTP Trailer alanlarının dahili HTTP başlıklarına kopyalanıp
      kopyalanmayacağını belirler. Kopyalama işlemi istek gövdesi tamamen
      alındığında gerçekleşir, çoğu başlık işleminin çok sonra istek
      başlıklarını inceleme veya değiştirme şansı olur.
    
    
    Bu seçenek, Trailer alanlarını daima kopyalayan 2.4.11 öncesi
      dağıtımlarla uyumluluk için vardır.

    Mutex Yönergesi
    

    

    Açıklama:Muteks mekanizmasını ve kilit dosyası dizinini tüm muteksler veya belirtilenler için yapılandırır
    

    Sözdizimi:Mutex mekanizma [default|muteks-ismi] ... [OmitPID]
    

    Öntanımlı:Mutex default
    

    Bağlam:sunucu geneli
    

    Durum:Çekirdek
    

    Modül:core
    

    Uyumluluk:Apache HTTP Sunucusunun 2.3.4 ve sonraki sürümlerinde
    kullanılabilmektedir.
    

    
    
    Mutex yönergesi httpd ve diğer modüllerin
      özkaynaklara erişimi dizgeleştirmekte kullandıkları mekanizmanın yanında
      isteğe bağlı olarak kilit dosyasının yerini belirler. İlk değiştirge
      olarak default belirtilirse tüm mutekslerin ayarları
      değişir; ikinci değiştirge olarak bir muteks ismi belirtilirse (aşağıdaki
      tabloya bakın) yalnızca bu muteksin öntanımlıları değişir.
    

    
    Mutex yönergesi genelde aşağıdaki istisnai
      durumlarda kullanılır:
    

    
      
        
    • İşlevsel veya başarımsal bir soruna sahip APR
          tarafından öntanımlı mekanizma seçildiği takdirde muteks
          mekanizmasını değiştirmek için
      • 

        
    • Öntanımlı dizin, kilitlemeyi desteklemediği takdirde dosya tabanlı
          muteksler tarafından kullanılan dizini değiştirmek için
      • 
    
    

    
    Destekleyen modüller
    
    
    Bu yönerge sadece ap_mutex_register() API'si kullanılarak
      çekirdek sunucuda imlenmiş muteksleri yapılandırır. httpd ile birlikte
      dağıtılan tüm modüller Mutex yönergesini
      destekler, fakat üçüncü parti modüllerin hepsi desteklemeyebilir. Bu
      yönergenin desteklenip desteklenmediğini öğrenmek için üçüncü parti
      modülün belgelerini inceleyin; destekliyorsa muteks ad(lar)ı
      belirtilmiştir.
    
    
    

    
    Kullanılabilen muteks mekanizmaları:
    
    
      
        
    • default | yes
        
      APR tarafından saptanan öntanımlı kilitleme
          gerçeklenimini seçer. Öntanımlı kilitleme gerçeklenimi
          httpd -V seçeneği ile çalıştırılarak
          öğrenilebilir.
      • 

        
    • none | no
        
      Muteksi etkin şekilde iptal eder. Buna bir mutekste izin
          verilebilmesi için modülün bunun geçerli bir seçim olduğunu
          belirtmesi gerekir. Daha fazla bilgi için modül belgelerini
          inceleyin.
      • 

        
    • posixsem
        
      POSIX semaforuna dayalı bir muteks çeşididir.
      
        
      Uyarı
      
        
      Süreçteki bir evre muteks parçalama arızalarını tutuyorsa,
          httpd'nin çökmesi sonucu, semafor sahipliği geri kazanılmaz.
      
        
      
        
      • 

        
    • sysvsem
        
      SystemV IPC semaforuna dayalı bir muteks çeşididir.
      
        
      Uyarı
      
        
      Semafor geri kazanılmadan süreçler çökerse SysV semaforlarının
          "sızıntı" yapması mümkündür.
      
        
      
        
      Güvenlik
      
        
      Semafor API'si, HTTP sunucusu ile aynı kullanıcı kimliği altında
          çalışan bir CGI (örn, suexec veya
          cgiwrapper gibi bir araç kullanmıyorsanız bütün
          CGI'ler) tarafından hizmet reddi saldırısı yapılmasına izin
          verir.
      
        
      
        
      • 

        
    • sem
        
      POSIX ve SystemV IPC semaforları arasından kullanılabilir "en iyi"
          semafor gerçeklenimini seçer.
      • 

        
    • pthread
        
      Süreç çaprazlamalı POSIX evre mutekslerine dayalı bir muteks
          çeşididir.
      
        
      Uyarı
      
        
      Çoğu sistemde, bir çocuk süreç bu gerçeklenim tarafından kullanılan
          bir muteksi tutarken olağandışı bir şekilde sonlanırsa httpd donar
          ve isteklere yanıt vermeyi durdurur. Bu olduğunda sunucuyu bu
          durumdan kurtarmak için elle yeniden başlatmak gerekir.
      
        
      Bu duruma karşı bir mekanizma sağlayan Solaris ve Linux dikkate
          değer bir istisnadır. Bu mekanizma, bir muteksi tutan bir çocuk
          süreç olağandışı bir şekilde sonlandıktan sonra muteksin
          kurtarılmasını sağlar.
      
        
      Sisteminiz POSIX uyumluysa veya
          pthread_mutexattr_setrobust_np() işlevini
          sağlıyorsa pthread seçeneğini rahatça
          kullanabilirsiniz.
      
        
      
        
      • 

        
    • fcntl:/path/to/mutex
        
      Muteks olarak fcntl() işlevini ve fiziksel bir (lock-)
          dosyasını kullanan bir muteks çeşididir.
      
        
      Uyarı
      
        
      Bu mekanizmaya dayalı çok sayıda muteks, çok evreli ve çok süreçli
          ortamlarda kullanıldığında, örneğin Solaris'te olduğu gibi
          fcntl() evrelerden bihaberse, geçerli muteks
          işlemlerinde donma hataları (EDEADLK) raporlanabilir.
      
        
      
        
      • 

        
    • flock:/path/to/mutex
        
      flock() işlevinin dosya kilitlemeyi sağlaması dışında
          fcntl:/path/to/mutex yöntemine benzer.
      • 

        
    • file:/path/to/mutex
        
      fcntl ve flock arasından kullanılabilir
          "en iyi" dosya kilitleme gerçeklenimini seçer.
      • 
    
    

    
    Çoğu mekanizma, yalnız kendilerini destekleyen platformlarda
      APR tarafından da destekleniyorsa kullanılabilir.
      Tüm platformlarda kullanılamayan mekanizmalar posixsem,
      sysvsem, sem, pthread, fcntl,
      flock ve file mekanizmalarıdır.
    

    
    fcntl ve flock dosya tabanlı mekanizmaları ile bir
      yol sağlandığı takdirde bu, kilit dosyasının oluşturulacağı dizindir.
      Öntanımlı dizin, httpd'nin çalışma anı dizini ServerRoot'a görelidir.
      /path/to/mutex için daima bir yerel diskteki dosya sistemi
      kullanılır, asla NFS- veya AFS gibi bir ağ dosya sistemi kullanılmaz.
      Dosya ismi daima muteks ismi ile başlar, buna modül tarafından sağlanan
      isteğe bağlı bir aşama dizgesi eklenebilir, OmitPID değeri
      belirtilmemişse httpd ebeveyn sürecinin süreç kimliği buna eklenerek
      dosya ismi eşsiz kılınır. Böylece, çok sayıda httpd süreci aynı kilit
      dosyası dizinini paylaştığı durumda çakışmalar önlenmiş olur. Örneğin,
      muteks ismi mpm-accept ise ve kilit dosyası dizini
      /var/httpd/locks ise ve ebeveyn süreç kimliği 12345 ise bu
      httpd sürecine ait kilit dosyası ismi
      /var/httpd/locks/mpm-accept.12345 olurdu.
    

    
    Güvenlik
    
    
    Muteks dosyalarını herkesin yazabildiği /var/tmp gibi
      dizinlere koymaktan kaçınmak en iyisidir. Örneğin, birinin aynı
      dizinde oluşturmaya çalıştığı bir dosya ile aynı isimde bir kilit
      dosyasını sunucunun da oluşturmaya çalıştığı durumda sunucu engellenerek
      bir hizmet reddi saldırısı gerçekleştirilmiş gibi olur.
    
    
    

    
    httpd ve birlikte dağıtılan modüller tarafından kullanılan mutekslerin
      isimleri:
    

    
    
            Muteks ismi

    mod_cgi kullanan CGI betiklerinin çalışmasına izin
        verilir.
    

      
    FollowSymLinks
    
      
    Sunucu bu dizindeki sembolik bağları izler. Bu öntanımlıdır.
      
    
      
    Sembolik bağlar izlense bile <Directory> bölümleriyle eşleşen dosya
       yolları değiştirilmez.
    
      
    FollowSymLinks ve
        SymLinksIfOwnerMatch Options sadece <Directory> bölümlerinde veya

    Sembolik bağ sınamaları, atlatılabilir yarış koşullarına konu
        olduğundan bu seçeneğin yokluğu bir güvenlik sınırlaması olarak
        değerlendirilmemelidir.

    FollowSymLinks ve
      SymLinksIfOwnerMatch Options sadece <Directory> bölümlerinde veya
      .htaccess dosyaları içinde çalışır.
    

      
    Sembolik bağ sınamaları, atlatılabilir yarış koşullarına konu
        olduğundan bu seçenek bir güvenlik sınırlaması olarak
        değerlendirilmemelidir.
    
      
    
    
    

    
    Normalde, bir dizine çok sayıda Options
      uygulanabilirse de, dizine en uygun olanı uygulanıp diğerleri yok
      sayılır; seçenekler katıştırılmaz (bkz, Bölümler Nasıl Katıştırılır?). Bununla birlikte, önüne bir
      + veya - simgesi konmuş seçenekler varsa, o
      seçenekler katıştırılır. Önüne + konmuş seçenekler
      mevcutlara eklenirken - konmuş seçenekler silinir.
    

    
    Bilgi
    
    
    + veya - imli seçenekler içeren
      Options ile imsiz seçenekler içerenlerin karışık
      olarak kullanılması aslında geçersiz bir sözdizimi olup sunucunun
      başlatılması sırasında sözdizimi denetiminin çıkmasıyla reddedilir.

<Directory "/web/docs/spec">
  Options Includes
</Directory>

      Includes seçeneği etkin olacaktır. Bununla birlikte, ikinci
      Options yönergesinde + ve
      - imleri kullanılırsa,
    

    
    <Directory "/web/docs">
  Options Indexes FollowSymLinks
</Directory>

<Directory "/web/docs/spec">
  Options +Includes -Indexes
</Directory>
    


    
    yapılandırmasıyla /web/docs/spec dizininde
      FollowSymLinks ve Includes seçenekleri etkin
      olacaktır.
    

    
    Ek Bilgi
    
      
    -IncludesNOEXEC veya -Includes kullanımı,
        önceki ayarların ne olduğuna bakılmaksızın sunucu taraflı içeriğin
        tamamen iptaline sebep olur.
    
    
    

    
    Herhangi bir başka değer belirtilmedikçe FollowSymlinks
      öntanımlıdır.

    Windows'ta ise Apache httpd 2.3.3 ve sonrasında
    kullanılabilmektedir.

    

    
    
    Bu yönerge dinlenen belli bir soket için kullanılacak protokolü
      belirler. Belirtilen protokol bir isteği hangi modülün ele alacağını ve
      AcceptFilter yönergesiyle yapılan özel
      eniyilemelere uygulanacak protokolü belirler.
    

    
    Bu yönerge çoğu yapılandırma için gerekli değildir. Belirtilmezse,
      port 443 için https öntanımlıdır ve diğer tüm portlar
      için http ntanımlıdır. Protokol, hangi modülün bir isteği
      işleyeceğini belirlemek ve AcceptFilter yönergesi ile protokole özgü
      eniyilemeleri uygulamak için kullanılır.
    

    
    Örneğin, https'i standartdışı bir portta çalıştırmak
      isterseniz protokolü şöyle belirtebilirsiniz:
    

    
    Protocol https

    Geçerli protokoller, http ve https bağlantıları için
       http/1.1 htps bağlantıları için h2 ve
       http bağlantıları için h2c protokolleridir. Modüller

    Kullanımından vazgeçilmiş protokollerin silinmesi gerekmez. Böyle

    Ana sunucu için belirtilen protokoller, kendi protokol yönergesi
       olmayan sanal konaklar için de geçerlidir. Diğer yandan sanal
       konaklarda protokol belirtilmesi ana sunucuda belirtien
       protollerin bu sanal konaklarda geçersiz olmasına sebep olur.

    Geçersizleştirme:FileInfo
    

    Durum:Çekirdek
    

    Modül:core
    

    Uyumluluk:Sadece Win32 için.
    

    
    
    Bu yönerge Apache httpd’nin CGI betiklerini çalıştıracak yorumlayıcıyı
      nasıl tespit edeceğini belirler. Script öntanımlı olup
      Apache httpd’nin yorumlayıcı olarak betiğin diyezli ünlem satırında
      (#! ile başlayan ilk satır) belirtilen yorumlayıcıyı
      kullanacağını belirtir. Win32 sistemlerinde bu satır genellikle
      şöyledir:
    

    
    #!C:/Perl/bin/perl.exe
    


    
    perl yorumlayıcının yeri PATH değişkeninde
      kayıtlı ise şöyle de olabilir:
    

    
    #!perl
    


    
    ScriptInterpreterSource Registry değeri ise betik dosyası
      uzantısının (.pl gibi) Windows Sicili içindeki
      HKEY_CLASSES_ROOT ağacında arama yapmak için bir arama
      anahtarı olarak kullanılmasını sağlar. Betik dosyasını çalıştırmak için
      tanımlanmış komutu bulmak için Shell\ExecCGI\Command yoluna,
      orada yoksa Shell\Open\Command yoluna bakılır. İkisi de
      yoksa son çare olarak Script seçeneğinin davranışına
      dönülür.
    

    
    Güvenlik
    
    
    ScriptAlias’lı dizinlerde
      Apache httpd bulduğu her dosyayı çalıştırmayı deneyeceğinden
      ScriptInterpreterSource Registry yapılandırmasını
      kullanırken dikkatli olun. Registry seçeneği genellikle
      çalıştırılmayacak dosyalar için istenmeyen program çağrılarına sebep
      olabilir. Örneğin, çoğu Windows sisteminde .htm dosyaları
      için ön tanımlı "open" komutu Microsoft Internet Explorer’ın
      çalıştırılmasına sebep olur; bu bakımdan, betik dizininde bulunan bir
      .htm dosyası için yapılan bir HTTP isteği tarayıcının sunucu
      artalanında çalıştırılmasına sebep olacaktır. Bu, sistemi bir kaç dakika
      içinde çökertmek için iyi bir yoldur.
    
    
    

    
    Registry-Strict seçeneği Registry
      seçeneğinin yaptığını
      Shell\ExecCGI\Command yolu için yapar. ExecCGI
      sistem tarafından bilinen bir anahtar olmadığından Windows Siciline elle
      kaydedilmesi gerekir ve dolayısıyla sisteminiz üzerinde istenmeyen
      program çağrılarına sebep olmaz.

    ServerAdmin yönergesi, sunucunun bir hata

      sağlanan değerin bir URL olmadığını saptarsa değerin bir eposta adresi
      olduğuna hükmeder ve önüne mailto: getirerek onu bir hiper
      bağ hedefi olarak kullanır. Çoğu CGI betiği bir eposta adresi
      belirtildiği kabulünü yaptığından değer olarak bir URL değil bir eposta
      adresi belirtmeniz önerilir. Eğer bir URL belirtecekseniz hedef sizin
      denetiminizde olan başka bir sunucuda bulunmalıdır, yoksa kullanıcılar
      hata durumunda bu adrese erişemeyebilirler.
    

    
    Kullanıcıların sunucu hakkında konuşurken isminizden bahsetmemeleri için
      burada belirtilecek adresin sırf bu işe adanmış bir adres olması daha
      iyidir. Örnek:

    Modül:core
    

    
    
    ServerName yönergesi, sunucunun kendini
      betimlemekte kullanacağı şema, konak adı ve port değerlerini belirler.
    
    

    
    isme dayalı sanal
      konaklar kullanılırken bir sanal konağı eşsiz bir şekilde betimlemek
      için ServerName kullanılır (muhtemelen
      ServerAlias ile birlikte).
    

    
    Ek olarak, UseCanonicalName
      yönergesine öntanımlı olmayan bir değer atanarak özüne yönlendiren
      URL'ler oluştururken de bu yönerge kullanılır.
    

    
    Örneğin, HTTP
      sunucusunun barındırıldığı makinenin ismi mail.example.com
      olduğu halde makinenin bir de www.example.com diye bir de
      DNS rumuzu varsa ve HTTP sunucunuzun bu rumuzla kendini
      özdeşleştirmesini isterseniz bunu şöyle belirtebilirsiniz:
    

    
    ServerName www.example.com
    


    
    ServerName yönergesi sunucu tanımının içinde
      herhangi bir yerde görünebilirse de her göründüğü yerde bir öncekini
      iptal eder.
    

    
    Bir ServerName ataması yapılmamışsa sunucu
      istemciye görünen sunucu ismini anlamak için önce işletim sistemine
      sistemin konak adını sorar. Bu başarılı olmazsa sistem üzerinde IP
      adresine bir ters DNS sorgusu yapar.
    

    
    ServerName yönergesinde bir port belirtilmediği
      takdirde sunucu, isteğin geldiği portu kullanacaktır. Öngörülebilirlik ve
      güvenilirlik açısından en iyisi ServerName
      yönergesini kullanarak açıkça bir konak ismi ve port belirtmektir.
    

    
    İsme dayalı sanal konaklar
      kullanıyorsanız, <VirtualHost> bölümü içindeki
      ServerName yönergesi, isteğin Host:
      başlığında bu sanal konakla eşleşecek konak ismini belirler.
    


    
    Bazen sunucu, bir ters vekil, yük dengeleyici veya SSL yük aktarım
      uygulaması gibi bir aygıtın arkasında çalışır. Böyle durumlarda sunucunun
      kendine yönelik URL’leri doğru üretebildiğinden emin olmak için
      ServerName yönergesinde istemcinin bağlanacağı
      https:// şeması ve port numarası belirtilir.
    

    
    Sunucunun kendine yönelik URL’lerin belirtilen portu içerip içermediğini
      veya istemcinin yaptığı istekte belirtilen port numarasının verilip
      verilmediğinin saptamasını sağlayan (örneğin, mod_dir

    TraceEnable extended ile sadece sınama ve tanı koyma
      amaçlarına yönelik olarak istek gövdelerine izin verilir. Asıl sunucu
      istek gövdesini 64kB ile sınırlar (Transfer-Encoding: chunked
      kullanılmışsa bölüm başlıkları için 8kB daha). Asıl sunucu yanıt

    Apache httpd‘nin çoğu durumda özüne yönelik URL‘ler (isteğin tekrar
      aynı sunucuya yapıldığı bir URL türü) oluşturması gerekir.
      UseCanonicalName On ile Apache httpd, sunucu için meşru
      ismi ve portu oluşturmak için
      ServerName
      yönergesinde belirtilen ismi ve portu kullanır. Bu isim  CGI'lerde
      SERVER_NAME ve SERVER_PORT değerlerinde ve tüm
      özüne yönelik URL’lerde kullanılır.
    

    
    UseCanonicalName Off ile Apache httpd, özüne yönelik URL’leri
      varsa istemci tarafından sağlanan konak ismini ve portu kullanarak
      oluşturur; bunlar istemci tarafından sağlanmamışsa yukarıda tanımlanan
      işleme başvurulur. Bu değerler, isme
      dayalı sanal konakları gerçekleştirirken kullanılan değerlerle aynı
      olup aynı istemcilerle kullanılabilir. SERVER_NAME ve
      SERVER_PORT CGI değişkenleri de istemci tarafından sağlanan
      isim ve portla oluşturulur.
    

    
    Bir örnek olarak, iç ağdaki istemcilerin sunucuya www gibi
      bir kısa isim kullanarak bağlandığı durumu ele alırsak daha yararlı
      olur. Kullanıcılar bir kısa isim ve bir dizin isminden oluşan ve bir
      / ile sonlandırılmamış http://www/splat şeklinde bir
      istek yaparlarsa, Apache httpd onları
      http://www.example.com/splat/ adresine yönlendirecektir.
      Eğer kimlik doğrulama da etkinse bu kullanıcının iki defa kimlik
      doğrulamasına sokulmasına sebep olacaktır (bir kere www
      için bir kere de www.example.com için; daha fazla bilgi için SSS’ye bakınız). Fakat UseCanonicalName Off
      olsaydı Apache httpd isteği http://www/splat/ adresine
      yönlendirecekti.
    

    
    UseCanonicalName DNS diye üçüncü bir seçenek daha vardır ve
      istek yaparken Host: başlığını kullanmayan eski istemcileri
      desteklemek amacıyla IP’ye dayalı sanal konaklarla kullanmak için
      tasarlanmıştır. Bu seçenek etkin olduğunda Apache httpd, istemciyi özüne
      yönelik URL’lerle doğru yere bağlamak için sunucu IP adresi üzerinde bir
      ters DNS sorgusu yapar.
    

    
    Uyarı
    
    
    Eğer CGI’ler SERVER_NAME değerleri için önkabuller
      yapıyorlarsa bu seçenek işlerinin bozulmasına yol açabilir. Aslında
      istemciler konak ismi olarak istedikleri değeri vermekte özgürdürler.
      Fakat eğer CGI, özüne yönelik URL’leri oluştururken sadece
      SERVER_NAME değerini kullanıyorsa bu istendiği gibi
      çalışacaktır.

    <VirtualHost> Yönergesi
    

    

    Açıklama:Sadece belli bir konak ismine ve porta uygulanacak yönergeleri barındırır.
    

    Sözdizimi:<VirtualHost
    adres[:port] [adres[:port]]
    ...> ... </VirtualHost>

    <VirtualHost> ve
      </VirtualHost> birlikte sadece belli bir sanal konağa
      uygulanacak yönergeleri sarmalamakta kullanılırlar. Bir sanal konak
      kapsamında belirtilebilecek her yönerge kullanılabilir. Sunucu belli bir
      sanal konak üzerindeki bir belge için bir istek aldığında <VirtualHost> bölümünde bulunan yapılandırma
      yönergelerini kullanır. adres şunlardan biri olabilir,
      istemlik olarak ikinokta imi ve bir port numarası (veya *)
      eklenebilir:
    

    
      
      
    • Sanal konağın IP adresi.
      • 

      
    • Sanal konağın IP adresi için tam nitelenmiş alan adı (önerilmez).
      
      • 

      
    • Tüm IP adresleri ile eşleşmek üzere * karakteri.
      • 

      
    • * için bir takma ad olarak _default_
        dizgesi.
      • 
    
    

    
    <VirtualHost 10.1.2.3:80>
  ServerAdmin webmaster@host.example.com
  DocumentRoot "/www/docs/host.example.com"
  ServerName host.example.com
  ErrorLog "logs/host.example.com-error_log"
  TransferLog "logs/host.example.com-access_log"
</VirtualHost>
    



    
    İsteğe bağlı port numarasını belirtmeyi mümkün kılmak için IPv6
      adresleri köşeli ayraç içine alınır. IPv6 adresi kullanılan bir
      örnek:
    

    
    <VirtualHost [2001:db8::a00:20ff:fea7:ccea]:80>
  ServerAdmin webmaster@host.example.com
  DocumentRoot "/www/docs/host.example.com"
  ServerName host.example.com
  ErrorLog "logs/host.example.com-error_log"
  TransferLog "logs/host.example.com-access_log"
</VirtualHost>
    


    
    Her sanal konağın ya farklı bir IP adresi ve port ile ya da farklı bir
      konak ismiyle eşleşmesi gerekir. Birinci durumda sunucu makinesinin çok
      sayıda adresten IP paketleri kabul edecek şekilde yapılandırılması
      gerekir. (Eğer makinede çok sayıda ağ arabirimi yoksa bu, işletim sistemi
      desteklediği takdirde ifconfig alias komutuyla
      sağlanabilir.)
    

    
    Ek Bilgi
    
    
    <VirtualHost> kullanımı Apache
      httpd’nin dinleyeceği adresler üzerinde belirleyici değildir. Apache
      httpd’nin doğru adresi dinlediğinden emin olmak için Listen kullanmanız gerekebilir.
    
    
    

    
    Her <VirtualHost> bloku içinde bir
      ServerName yönergesi mutlaka
      olmalıdır. Yokluğu halinde "ana" sunucu yapılandırmasındaki ServerName miras alınacaktır.
    

    
    Bir istek alındığında, sunucu isteği, sadece yerel IP adresi ve port
      çiftine dayalı en iyi eşleşen ilk <VirtualHost> bölümüne eşler. Joker kullanmayanlar daha
      yüksek önceliğe sahiptir. IP ve port çiftine dayalı bir eşleşme
      bulunamazsa istek için ana sunucu yapılandırması kullanılır.
    

    
    En iyi eşleşen IP adresi ve port çiftini birden fazla sanal konak
      kullanıyorsa sunucu bu sanal konaklar (liste) arasından istenen konak
      ismiyle en iyi eşleşeni seçer. Eşleşen hiçbir isme dayalı sanal konak
      yoksa listedeki IP adresi ile eşleşen ilk sanal konak kullanılır. Bunun
      sonucu olarak, belirtilen IP adresi ve port çifti için listedeki ilk
      sanal konak, bu IP adresi ve port çifti için öntanımlı sanal
      konaktır.
    

    
    Güvenlik
    
    
    Günlük dosyalarının sunucuyu çalıştıran kullanıcıdan başka herkes
      tarafından yazılabilen bir yerde saklanmasından dolayı ortaya çıkabilecek
      güvenlik sorunları hakkında daha ayrıntılı bilgi için güvenlik ipuçları belgesine
      bakınız.

    説明:Unix の ls コマンドや
    Win32 の dir シェルコマンドに似た
    ディレクトリインデックスを生成する
    

    ステータス:Base
    

    モジュール識別子:autoindex_module
    

    ソースファイル:mod_autoindex.c
    

    概要
    

      
    ディレクトリのインデックスは二つの情報源のうちの
      一つから生成できます:
    

    
      
      
    • 普通は index.html と呼ばれる
      ユーザによって書かれたファイル。
      DirectoryIndex
      ディレクティブでこのファイル名を設定します。
      これは mod_dir で制御されます。
      • 

      
    • もしくは、サーバによって生成された一覧。
      その他のディレクティブでこの一覧の書式を制御します。
      AddIcon, AddIconByEncoding と
      AddIconByType
      を使うことで、様々なファイルタイプに対してアイコン一覧を
      セットします。つまり、リストされたファイル毎に、
      ファイルにマッチした一番最初のアイコンが表示されます。
      これらは mod_autoindex で制御されます。
      • 
    
    
    
    望むならば、自動インデックス生成を完全に除去 (あるいは置換)
    できるように、この二つの機能は分離されています。
    

    
    自動インデックス生成は Options +Indexes
    を使うことで有効になります。詳細については、
    Options
    ディレクティブをご覧下さい。
    

    
    もし FancyIndexingオプションが
    IndexOptions
    ディレクティブに与えられているならば、
    列の先頭は表示の順番を制御するリンクになります。
    先頭のリンクを選択すると、一覧は再生成されて
    その列の値でソートされます。
    同じ先頭を続けて選択すると、交互に昇順と降順とになります。
    これらの列の先頭のリンクは、
    IndexOptions
    ディレクティブの
    SuppressColumnSorting
    オプションで消すことができます。
    

    
    "Size" でソートした場合は、用いられるのは
    実際のファイルのサイズであって、
    表示の値ではないことに注意してください -
    たとえ両方ともが "1K" と表示されていたとしても、
    1010 バイトのファイルは必ず 1011
    バイトのファイルよりも前 (昇順の場合) に表示されます。

    Autoindex リクエストクエリー引数
    
    

    
    Apache 2.0.23 で、
    コラムソートのためにクエリー引数を再編成して、
    新しいクエリーオプションのグループを導入しました。
    出力に対するクライアントのすべての制御を効率的に抹消
    できるように、
    IndexOptions
    IgnoreClient が導入されました。
    

    
    コラムソートのヘッダそれ自体が、
    下記のソートクエリーオプションを付加する
    自分自身を参照するリンクです。
    下記のオプションのどれでも、
    ディレクトリリソースへのリクエストに加えることができます。
    

    
      
      
    • C=N は、ファイル名でソートします。
      • 

      
    • C=M は、更新日時、
      ディレクトリ、ファイル名の順でソートします。
      • 

      
    • C=S は、サイズ、
      ディレクトリ、ファイル名の順でソートします。
      • 

      
    • C=D は、説明、
      ディレクトリ、ファイル名の順でソートします。
      • 

      
    • O=A は、昇順で表をソートします。
      • 

      
    • O=D は、降順で表をソートします。
      • 

      
    • F=0 は、単純な表の書式にします。
      (FancyIndex ではありません。)
      • 

      
    • F=1 は、FancyIndex 
      表示の表の書式にします。
      • 

      
    • F=2 は、表を HTML 
      のテーブルを使った FancyIndex の書式にします。
      • 

      
    • V=0 
      は、バージョンによるソートを無効にします。
      • 

      
    • V=1 
      は、バージョンによるソートを有効にします。
      • 

      
    • P=pattern 
      は、与えられた pattern
      に適合したファイルのみを表示します。
      • 
    
    

    
    "P (パターンの P)" クエリー引数は、
    通常の IndexIgnore
    ディレクティブが処理された後に検査され、
    ファイル名全てが、他の autoindex
    リスト処理と同様の判定基準下に置かれ続ける
    ことに注意してください。
    mod_autoindex のクエリー引数パーサ (解析) は、
    認識不能なオプションにぶつかると即座に停止します。
    クエリー引数は上の表に従って
    正しい形式になっていなければなりません。
    

    
    下の単純な例は、これらのクエリーオプションを
    表します。これをそのまま切り取って HEADER.html 
    ファイルに保存することもできます。
    mod_autoindex が X=Go 入力にぶつかる前に
    引数が全て解釈されるように、
    未知の引数 "X" はリストの最後に置かれています。

    IndexOptions 
    のキーワードをご覧下さい。
    

    
    警告
    
      
    AddDescription 
      で定義された説明テキストは、タグや文字列といった
      HTML マークアップを含むことができます。
      もし、説明コラムの幅によってタグ付けされた要素が丸め込まれた
       (太字の語句の最後が切れるといった) 場合、
      出力結果は、ディレクトリ一覧の残りの部分に影響を与えるでしょう。

    インデックス一覧の先頭に挿入するファイルの名前を設定します。
    Filename は取り込むファイルの名前です。
    

    
    例
    
      HeaderName HEADER.html
    
    

    
    
      
    HeaderName も ReadmeName 
      も両方とも現在は、filename 
      をインデックスされているディレクトリに用いられた URI
      に対する相対 URI パスとして扱います。
      filename がスラッシュで始まる場合は、
      DocumentRoot
      からの相対パスとなります。
    

      
    例
    
        HeaderName /include/HEADER.html
      
    

      
    filename は
      メジャーコンテントタイプが "text/*" 
       (例えば、text/html, 
      text/plain 等です。) 
      のドキュメントとして解決
      されなければなりません。これはつまり、
      もし CGI スクリプトの実際のファイルタイプが
      次のディレクティブのようにして実際の出力とは異なって
      text/html としてマークされている場合、
      filename
      は CGI スクリプトを参照するかも知れない、
      ということを意味します:
    

      
    
        AddType text/html .cgi
      
    

      
    Options MultiViews が
      有効になっている場合は、
      コンテントネゴシエーション
      が行なわれます。
      もし filename が (CGI スクリプトでない) 静的な 
      text/html ドキュメントで解決され、
      options
      Includes か IncludesNOEXEC
      が有効になっている場合は、
      ファイルはサーバーサイドインクルードで処理されます
      (mod_include ドキュメントを参照して下さい)。
    
    
    

    
    もし HeaderName で指定されたファイルが
    HTML ドキュメントの開始部分 (<html>, <head>, 
    等) を含んでいたら、
    IndexOptions
    +SuppressHTMLPreamble
    を設定して、これらのタグが繰り返されないようにしたいと思うでしょう。

    モジュール:mod_autoindex
    

    
    
    IndexOptions 
    は、ディレクトリインデックスの挙動を指定します。
    option は次のどれかです:
    

    
    
      
    Charset=character-set (Apache 2.0.61
      以降)
    

      
    Charset キーワードで、
      生成されるページの文字セットを指定できます。
      下位のファイルシステムが Unicode ベースかどうかに依存しますが、
      デフォルト値は ISO-8859-1 か UTF-8
      になります。

      
    Example:
    
        IndexOptions Charset=UTF-8
      
    
      
    

      
    Type=MIME content-type (Apache 2.0.61
      以降)
    

      
    Type キーワードで、
      生成されるページの MIME コンテントタイプを指定できます。
      デフォルト値は text/html になります。

      
    Example:
    
        IndexOptions Type=text/plain
      
    
      
    

      
    DescriptionWidth=[n | *]
      (2.0.23 以降)
    

      
    DescriptionWidth 
      キーワードは説明コラムの幅を文字数で指定することができます。
    

      
    -DescriptionWidth (または非設定) で、
      mod_autoindex が最適な幅を計算するようにできます。
    

      
    DescriptionWidth=n 
      で、コラム幅を n バイトに固定します。
    

      
    DescriptionWidth=* 
      は、最長の説明に合わせて必要な長さまでコラムを延ばします。
    

      
    説明を丸め込んだ場合特有の危険については
      AddDescription
      セクションをお読み下さい。
    

      
    FancyIndexing
    

      
    飾り付きインデックスをオンにします。
    

      
    FoldersFirst
      (2.0.23 以降)
    

      
    このオプションが有効になった場合、サブディレクトリの一覧は
      必ず最初に現われて、通常のファイルはその後に続きます。
      一覧は基本的には、ファイルとディレクトリの二つの部分に分けられて、
      それぞれは別々にソートされ、その後サブディレクトリを先にして
      表示が行なわれます。例えばソート順が名前の降順になっていて、
      FoldersFirst が有効になっている場合は、
      サブディレクトリ Zed はサブディレクトリ
      Beta よりも前にリストされ、通常のファイル
      Gamma や Alpha
      よりも前にリストされます。このオプションは
      FancyIndexing
      も有効になっているときにのみ有効です。
    

      
    HTMLTable (実験的、
      Apache 2.0.23 以降)
    

      
    この実験的なオプションは FancyIndexing とともに指定することで、
      飾りの付いたディレクトリ一覧のためにテーブルを使った単純な表を作ります。
      これは古いブラウザを混乱させるかもしれないことに注意してください。
      WinNT やその他 utf-8 
      が有効なプラットホームのように、ファイル名や説明テキストが
      右読みになったり左読みになりえる場合は特に必要です。
    

      
    IconsAreLinks
    

      
    これは、FancyIndexing において、
      アイコンもファイル名へのリンクの一部にします。
    

      
    IconHeight[=pixels]
    

      
    このオプションが、IconWidth とともに
      使われている場合は、サーバはファイルアイコンのための
      img タグに height と width
      属性を取り込むようになります。
      これによって、イメージ全てをロードし終わるまで待たなくても、
      ブラウザはページレイアウトをあらかじめ計算することができます。
      このオプションに何も値が与えられなければ、Apache
      ソフトウェアで提供されているアイコンの標準の高さが
      デフォルトなります。
    

      
    IconWidth[=pixels]
    

      
    このオプションが、IconHeight とともに使われている場合は、
      サーバはファイルアイコンのための img
      タグに height と width
      属性を取り込むようになります。
      これによって、イメージ全てをロードし終わるまで待たなくても、
      ブラウザはページレイアウトをあらかじめ計算することができます。
      このオプションに何も値が与えられなければ、Apache
      ソフトウェアで提供されているアイコンの標準の高さが
      デフォルトなります。
    

      
    IgnoreCase
    

      
    このオプションが有効であると、ファイル名は大文字小文字を区別せずにソートされます。
      例えばファイル名が昇順でソートされ、IgnoreCase が有効であれば、
      Zeta は alfa の後にリストされます
      (注意: GAMMA は常に gamma の前になります)。
    

      
    IgnoreClient
    

      
    このオプションで mod_autoindex は、
      クライアントからの全てのクエリー変数を無視するようになります。
      これはソート順も含みます。
      (つまり SuppressColumnSorting
      も有効になります。)
    

      
    NameWidth=[n 
	       | *]
    

      
    NameWidth キーワードでファイル名コラムの幅をバイト数で
      指定できます。
    

      
    -NameWidth (または非設定) で、
      mod_autoindex が最適な幅を計算するようにできます。
    

      
    NameWidth=n 
      で、コラム幅を n バイトに固定します。
    

      
    NameWidth=*
      は、必要な長さまでコラムを延ばします。
    

      
    ScanHTMLTitles
    

      
    FancyIndexing のために、
       HTML ドキュメントからタイトルを取り出すことを可能にします。
      もしファイルに
      AddDescription
      で説明が与えられていなければ、
      httpd は title タグの値を読むためにドキュメントを読み始めます。
      これは CPU や disk に負荷をかけます。
    

      
    ShowForbidden
    

      
    通常 Apache はサブリクエストの結果がHTTP_UNAUTHORIZED や
      HTTP_FORBIDDEN のファイルは一覧に表示しません。
      このオプションを指定すると、そのようなファイルも一覧に表示します。
    

      
    SuppressColumnSorting
    

      
    もし指定されていれば、Apache は
      FancyIndexing で表示されているディレクトリ一覧での
      コラムの先頭を、ソートのためのリンクにしなくなります。
      デフォルトの挙動は、リンクとします。
      コラムの先頭を選ぶとコラムの値に従ってディレクトリリストを
      ソートします。
      Apache 2.0.23 以前では、これは同時に
      ソート文字列のためのクエリー引数の解析も無効にします。
      
      この挙動は Apache 2.0.23 では
      IndexOptions
      IgnoreClient で制御されるようになっています。
    

      
    SuppressDescription
    

      
    これは FancyIndexing におけるファイルの説明を消去します。
      デフォルトでは、説明は定義されておらず、
      このオプションを使うと他のために 23
      文字の空白を稼ぐことができます。 ファイルの説明に関する情報は、
      AddDescription 
      をご覧下さい。また、説明のコラムサイズを制限する
      DescriptionWidth
      インデックスオプションもご覧下さい。
    

      
    SuppressHTMLPreamble
    

      
    通常、
      HeaderName
      ディレクティブで指定したファイルを
      ディレクトリが実際に含んでいれば、標準的な HTML プリアンブル
      (<html>, <head>, 等) の後に、
      モジュールはファイルの中身をインクルードします。
      SuppressHTMLPreamble オプションは、
      この挙動を無効にできて、
      モジュールがヘッダーファイルの中身から表示を始めます。
      この場合、ヘッダーファイルは正しい HTML
      命令を含んでいなければなりません。
      ヘッダーファイルが存在しない場合は、プリアンブルは通常通り
      生成されます。
    

      
    SuppressIcon (Apache
      2.0.23 以降)
    

      
    
      これは FancyIndexing の一覧からアイコンを消去します。
      SuppressIcon と SuppressRules
      と組合わせることによって正しい HTML 3.2 の出力が得られます。
      HTML 3.2 の最終規格は、 img と hr
      が pre ブロックに入る (FancyIndexing 一覧で書式に使われています) 
      ことを禁止しています。
    

      
    SuppressLastModified
    

      
    FancyIndexing 一覧において最終更新日時の表示を消去します。
    

      
    SuppressRules
       (Apache 2.0.23 以降) 
    

      
    ディレクトリ一覧において水平区切り線 (hr タグ) を消去します。
      SuppressIcon と SuppressRules
      と組合わせることによって正しい HTML 3.2 の出力が得られます。
      HTML 3.2 の最終規格は、 img と hr
      が pre ブロックに入る (FancyIndexing 一覧で書式に使われています) 
      ことを禁止しています。
    

      
    SuppressSize
    

      
    FancyIndexing 一覧においてファイルサイズの表示を消去します。
    

      
    TrackModified
	       (Apache 2.0.23 以降)
    

      
    これは HTTP ヘッダ中に、
      ディレクトリの Last-Modified や 
      ETag を含めます。
      これは、オペレーティングシステムやファイルシステムが
      適切な stat() の返り値を返す場合にのみ有効です。
      いくつかの UNIX システム、OS2 の JFS や Win32 の NTFS
      ボリュームはそうなっています。
      例えば、OS2 と Win32 FAT ボリュームはそうではありません。
      この機能が有効になると、クライアントやプロキシは
      HEAD リクエストを行うことによって、
      ファイル一覧の変化を追跡することができるようになります。
      オペレーティングシステムによっては、新規ファイルや
      移動ファイルは正しく追跡するけれども、
      ディレクトリ中のファイルのサイズや日付は追跡しないということに
      注意してください。
      既に存在するファイルのサイズや日付のスタンプが変化しても、
      全ての Unix プラットホームでは、
      Last-Modified ヘッダーを更新しません。
      もしこれが重要であれば、
      このオプションを無効のままにしてください。
    

      
    VersionSort
      (Apache 2.0a3 以降)
    

      
    VersionSort キーワードはバージョン番号を含んだファイルが
      自然な方法でソートされるようにします。
      文字列は通常通りソートされ、
      それ以外の、説明や名前中の数となる部分文字列は
      その数値で比較されます。

      
    例:
    
        foo-1.7
    
        foo-1.7.2
    
        foo-1.7.12
    
        foo-1.8.2
    
        foo-1.8.2a
    
        foo-1.12
      
    

      
    番号が 0 から始まる場合は、端数と考えられます
    

      
    
        foo-1.001
    
        foo-1.002
    
        foo-1.030
    
        foo-1.04
      
    
      
    

      
    XHTML
      (Apache 2.0.49 以降)
    

      
    XHTML キーワードを指定すると、mod_autoindex
      は HTML 3.2 の代わりに XHTML 1.0 のコードを出力するようになります。
    
    
    

   
   
    増減指定できる IndexOptions
    
   
    
     
    Apache 1.3.3 では、
     IndexOptions 
     ディレクティブの扱いで幾つかの大きな変化が導入されました。
     特に、
    

     
      
     
    • 一つのディレクトリに対する複数の
     IndexOptions 
     ディレクティブは、現在では一つにマージされます。

     
      
       <Directory /foo>
       
         IndexOptions HTMLTable
      
         IndexOptions SuppressColumnsorting
             
       </Directory>
     
      

     
      の結果は、次の指定と同一の結果になります。
      

     
      
       IndexOptions HTMLTable SuppressColumnsorting
     
      
     
      • 

     
    • 増減構文
     (すなわち、'+' や '-'
     の接頭辞が付くキーワード) の追加。
      • 
     
    

     
    '+' や '-' 接頭辞の付いたキーワードに出会うとそれは、
     その時点での IndexOptions
     の設定 (これは上流のディレクトリを受け継ぎます) 
     に対して適応されます。
     しかしながら、接頭辞の付かないキーワードが処理された場合は、
     受け継いだオプション全てとそれまで出会った増減設定全てが
     消去されます。次の例を考えてみてください:
    

     
    
       IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
    
       IndexOptions +SuppressSize
     
    

     
    最終的な効果は
     IndexOptions FancyIndexing +SuppressSize
     と同一です。
     接頭辞の付かない FancyIndexing
     でそれ以前の増減キーワードは無効になり、
     その後の累積が始まるからです。
    

     
    あるディレクトリにおいて上位のディレクトリに指定された設定に影響されることなく
     IndexOptions を設定したい場合、
     + や -
     接頭辞の付かないキーワードで設定してください。

    インデックスオプションと併せて用いられます。
    デフォルトでは、FancyIndexing 
    のディレクトリ一覧はファイル名の昇順で表示されます。
    IndexOrderDefault
    で、初期状態の表示順番を変えることができます。
    

    
    IndexOrderDefault
    は二つの引数をとります。一つ目はソートの方向を指示する
    Ascending か Descending のいずれかです。
    二つ目の引数は Name, Date,
    Size か Description 
    のいずれか一つのキーワードであって、1つ目のソートキーを指定します。
    2つ目のソートキーは常にファイル名の昇順になります。
    

    
    このディレクティブと SuppressColumnSorting
    インデックスオプションとを組み合わせることで、
    ディレクトリ一覧をある特定の順番でのみ表示するようにできます。
    これは、
    クライアントが別の順番でディレクトリ一覧をリクエストすることを防ぎます。

    filename がスラッシュで始まる場合は、
    DocumentRoot
    からの相対パスとなります。
    

    
    例
    
      ReadmeName FOOTER.html

    Sommaire
    


    
    Sur les systèmes d'exploitation sélectionnés, ce module peut être
    utilisé pour charger des modules dans le serveur HTTP Apache en cours d'exécution
    grâce au mécanisme des Dynamic Shared Object ou Objets Partagés
    Dynamiquement (DSO), et évite ainsi de devoir effectuer une
    recompilation.
    

    
    Sous Unix, le code chargé provient en général de fichiers objet
    partagés possèdant en général l'extension .so, alors
    que sous Windows, l'extension peut être soit .so, soit
    .dll.
    

    
    Avertissement
    
    
    En général, les modules compilés pour une version majeure du
    serveur HTTP Apache ne fonctionneront pas avec une autre (par
    exemple de 1.3 à 2.0 ou 2.0 à 2.2). D'une version majeure à l'autre,
    il y a souvent des modifications d'API qui nécessitent des
    modifications du module pour qu'il puisse fonctionner avec la
    nouvelle version.

    Création de modules chargeables pour
Windows
    

    
    Note
    
    
    Sous Windows, où les modules chargeables possèdent en général
    l'extension de nom de fichier .dll, les modules Apache
    httpd se nomment mod_nom-module.so, tout comme sur les
    autres plates-formes. Vous trouverez cependant encore des modules
    tiers, comme PHP par exemple, qui continuent d'utiliser la
    convention de nommage avec extension .dll.
    

    
    Bien que mod_so puisse encore charger des modules
    possèdant un nom du style ApacheModuleFoo.dll,
    il est préférable d'utiliser la
    nouvelle convention de nommage ; si vous modifiez votre module
    chargeable pour la version 2.0, veuillez aussi modifier son nom pour
    respecter cette nouvelle convention.
    

    
    Les API des modules Apache httpd sous Unix et Windows sont identiques.
    Alors que certains modules s'appuient sur certains
    aspects de l'architecture Unix non présents dans Windows, et ne
    fonctionneront donc pas sur cette dernière plate-forme, de nombreux
    modules fonctionnent sous Windows avec peu ou pas de modification
    par rapport à leur version Unix.
    

    
    Lorsqu'un module fonctionne, il peut être ajouté au serveur de
    deux manières. Sous Unix, il peut être compilé dans le serveur.
    Comme Apache httpd pour Windows ne dispose pas du programme
    Configure propre à Apache httpd pour Unix, le fichier source
    du module doit être ajouté au fichier projet Apache de base, et ses
    symboles ajoutés au fichier os\win32\modules.c.
    

    
    La seconde méthode consiste à compiler le module en tant que DLL,
    à savoir une bibliothèque partagée qui pourra être chargée dans le
    serveur en cours d'exécution via la directive
    LoadModule. Ces modules DLL
    peuvent être distribués et exécutés sur toute installation d'Apache
    httpd pour Windows, sans avoir à recompiler le serveur.
    

    
    Pour créer un module DLL, il est nécessaire d'apporter une légère
    modification à son fichier source : l'enregistrement du module doit
    être exporté depuis la DLL (qui sera elle-même créée plus tard ;
    voir plus loin). Pour ce faire, ajoutez la macro
    AP_MODULE_DECLARE_DATA (définie dans les fichiers
    d'en-têtes d'Apache httpd) à la définition de l'enregistrement de votre
    module. Par exemple, si votre module est déclaré comme suit :
    


    
    module foo_module;

    

    
    Remplacez cette ligne par :
    

    
    module AP_MODULE_DECLARE_DATA foo_module;

    

    
    Notez que cette macro ne sera prise en compte que sous Windows,
    si bien que le module poura être utilisé sans changement sous Unix,
    si besoin est. Alternativement, si vous êtes familier avec les
    fichiers .DEF, vous pouvez les utiliser pour exporter
    l'enregistrement du module.
    

    
    Maintenant, nous sommes prêts à créer une DLL contenant notre
    module. Il va falloir pour cela la lier avec la bibliothèque
    d'export libhttpd.lib qui a été créée au cours de la compilation de
    la bibliothèque partagée libhttpd.dll. Il sera peut-être aussi
    nécessaire de modifier la configuration du compilateur pour
    s'assurer que les fichiers d'en-têtes d'Apache httpd seront correctement
    localisés. Vous trouverez cette bibliothèque à la racine du
    répertoire des modules de votre serveur. Il est souhaitable
    d'utiliser un fichier de module .dsp existant dans l'arborescence
    afin de s'assurer que l'environnement de compilation est
    correctement configuré, mais vous pouvez aussi comparer les options
    de compilation et d'édition de liens à votre fichier .dsp.
    

    
    Ceci devrait créer une version DLL de votre module. Il vous
    suffit maintenant de l'enregistrer dans le répertoire
    modules à la racine de votre serveur, et d'utiliser la
    directive LoadModule pour la charger.

    Apache Module mod_proxy_html
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Rewrite HTML links in to ensure they are addressable
from Clients' networks in a proxy context.
    

    Status:Base
    

    Module Identifier:proxy_html_module
    

    Source File:mod_proxy_html.c
    

    Compatibility:Version 2.4 and later.  Available as a third-party module
for earlier 2.x versions
    

    Summary
    


    This module provides an output filter to rewrite HTML links in a
proxy situation, to ensure that links work for users outside the proxy.
It serves the same purpose as Apache's ProxyPassReverse directive does
for HTTP headers, and is an essential component of a reverse proxy.
    


    For example, if a company has an application server at
appserver.example.com that is only visible from within
the company's internal network, and a public webserver
www.example.com, they may wish to provide a gateway to the
application server at http://www.example.com/appserver/.
When the application server links to itself, those links need to be
rewritten to work through the gateway. mod_proxy_html serves to rewrite
<a href="http://appserver.example.com/foo/bar.html">foobar</a> to
<a href="http://www.example.com/appserver/foo/bar.html">foobar</a>
making it accessible from outside.
    


    mod_proxy_html was originally developed at WebÞing, whose
extensive documentation may be useful to users.

    ProxyHTMLBufSize Directive
    

    

    Description:Sets the buffer size increment for buffering inline scripts and
stylesheets.
    

    Syntax:ProxyHTMLBufSize bytes
    

    Default:ProxyHTMLBufSize 8192
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    In order to parse non-HTML content (stylesheets and scripts) embedded
in HTML documents, mod_proxy_html
has to read the entire script or stylesheet into a buffer.  This buffer will
be expanded as necessary to hold the largest script or stylesheet in a page,
in increments of bytes as set by this directive.
    

    The default is 8192, and will work well for almost all pages.  However,
if you know you're proxying pages containing stylesheets and/or
scripts bigger than 8K (that is, for a single script or stylesheet,
NOT in total), it will be more efficient to set a larger buffer
size and avoid the need to resize the buffer dynamically during a request.

    ProxyHTMLCharsetOut Directive
    

    

    Description:Specify a charset for mod_proxy_html output.
    

    Syntax:ProxyHTMLCharsetOut Charset | *
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    This selects an encoding for mod_proxy_html output.  It should not
normally be used, as any change from the default UTF-8
(Unicode - as used internally by libxml2) will impose an additional
processing overhead.  The special token ProxyHTMLCharsetOut *
will generate output using the same encoding as the input.
    

    Note that this relies on mod_xml2enc being loaded.
    


    

    top
    

    ProxyHTMLDocType Directive
    

    

    Description:Sets an HTML or XHTML document type declaration.
    

    Syntax:ProxyHTMLDocType HTML|XHTML [Legacy]
    OR

    ProxyHTMLDocType fpi [SGML|XML]
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    In the first form, documents will be declared as HTML 4.01 or XHTML 1.0
according to the option selected.  This option also determines whether
HTML or XHTML syntax is used for output.   Note that the format of the
documents coming from the backend server is immaterial: the parser will
deal with it automatically.  If the optional second argument is set to
Legacy, documents will be declared "Transitional", an option that may
be necessary if you are proxying pre-1998 content or working with defective
authoring/publishing tools.
    

    In the second form, it will insert your own FPI.  The optional second
argument determines whether SGML/HTML or XML/XHTML syntax will be used.
    

    The default is changed to omitting any FPI,
on the grounds that no FPI is better than a bogus one.  If your backend
generates decent HTML or XHTML, set it accordingly.
    

    If the first form is used, mod_proxy_html
will also clean up the HTML to the specified standard.  It cannot
fix every error, but it will strip out bogus elements and attributes.
It will also optionally log other errors at LogLevel Debug.

    ProxyHTMLEnable Directive
    

    

    Description:Turns the proxy_html filter on or off.
    

    Syntax:ProxyHTMLEnable On|Off
    

    Default:ProxyHTMLEnable Off
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
module for earlier 2.x versions.
    

    
    
    A simple switch to enable or disable the proxy_html filter.
    If mod_xml2enc is loaded it will also automatically
    set up internationalisation support.
    
    
    Note that the proxy_html filter will only act on HTML data
    (Content-Type text/html or application/xhtml+xml) and when the
    data are proxied.  You can override this (at your own risk) by
    setting the PROXY_HTML_FORCE environment variable.
    


    

    top
    

    ProxyHTMLEvents Directive
    

    

    Description:Specify attributes to treat as scripting events.
    

    Syntax:ProxyHTMLEvents attribute [attribute ...]
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    Specifies one or more attributes to treat as scripting events and
apply ProxyHTMLURLMaps to where enabled.
You can specify any number of attributes in one or more
ProxyHTMLEvents directives.
    

    Normally you'll set this globally.  If you set ProxyHTMLEvents in more than
one scope so that one overrides the other, you'll need to specify a complete
set in each of those scopes.
    

    A default configuration is supplied in proxy-html.conf
and defines the events in standard HTML 4 and XHTML 1.
    


    

    top
    

    ProxyHTMLExtended Directive
    

    

    Description:Determines whether to fix links in inline scripts, stylesheets,
and scripting events.
    

    Syntax:ProxyHTMLExtended On|Off
    

    Default:ProxyHTMLExtended Off
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    Set to Off, HTML links are rewritten according to the
ProxyHTMLURLMap directives, but links appearing
in Javascript and CSS are ignored.
    

    Set to On, all scripting events (as determined by
ProxyHTMLEvents) and embedded scripts or
stylesheets are also processed by the ProxyHTMLURLMap
rules, according to the flags set for each rule.  Since this requires more
parsing, performance will be best if you only enable it when strictly necessary.

    
You'll also need to take care over patterns matched, since the parser has no
knowledge of what is a URL within an embedded script or stylesheet.
In particular, extended matching of / is likely to lead to
false matches.

    ProxyHTMLFixups Directive
    

    

    Description:Fixes for simple HTML errors.
    

    Syntax:ProxyHTMLFixups [lowercase] [dospath] [reset]
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    This directive takes one to three arguments as follows:
    

      

    • lowercase Urls are rewritten to lowercase
      • 

    • dospath Backslashes in URLs are rewritten to forward slashes.
      • 

    • reset Unset any options set at a higher level in the configuration.
      • 

    

    Take care when using these.  The fixes will correct certain authoring
mistakes, but risk also erroneously fixing links that were correct to start with.
Only use them if you know you have a broken backend server.
    


    

    top
    

    ProxyHTMLInterp Directive
    

    

    Description:Enables per-request interpolation of
ProxyHTMLURLMap rules.
    

    Syntax:ProxyHTMLInterp On|Off
    

    Default:ProxyHTMLInterp Off
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
module for earlier 2.x versions
    

    
    
    This enables per-request interpolation in
    ProxyHTMLURLMap to- and from- patterns.
    
    
    If interpolation is not enabled, all rules are pre-compiled at startup.
    With interpolation, they must be re-compiled for every request, which
    implies an extra processing overhead.  It should therefore be
    enabled only when necessary.

    ProxyHTMLLinks Directive
    

    

    Description:Specify HTML elements that have URL attributes to be rewritten.
    

    Syntax:ProxyHTMLLinks element attribute [attribute2 ...]
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    Specifies elements that have URL attributes that should be rewritten
using standard ProxyHTMLURLMaps.
You will need one ProxyHTMLLinks directive per element,
but it can have any number of attributes.
    

    Normally you'll set this globally.  If you set ProxyHTMLLinks in more than
one scope so that one overrides the other, you'll need to specify a complete
set in each of those scopes.
    

    A default configuration is supplied in proxy-html.conf
and defines the HTML links for standard HTML 4 and XHTML 1.
    

    Examples from proxy-html.conf
    ProxyHTMLLinks  a          href
ProxyHTMLLinks  area       href
ProxyHTMLLinks  link       href
ProxyHTMLLinks  img        src longdesc usemap
ProxyHTMLLinks  object     classid codebase data usemap
ProxyHTMLLinks  q          cite
ProxyHTMLLinks  blockquote cite
ProxyHTMLLinks  ins        cite
ProxyHTMLLinks  del        cite
ProxyHTMLLinks  form       action
ProxyHTMLLinks  input      src usemap
ProxyHTMLLinks  head       profile
ProxyHTMLLinks  base       href
ProxyHTMLLinks  script     src for

    ProxyHTMLMeta Directive
    

    

    Description:Turns on or off extra pre-parsing of metadata in HTML
<head> sections.
    

    Syntax:ProxyHTMLMeta On|Off
    

    Default:ProxyHTMLMeta Off
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
module for earlier 2.x versions.
    

    
    
    This turns on or off pre-parsing of metadata in HTML
    <head> sections.
    
    
    If not required, turning ProxyHTMLMeta Off will give a small
    performance boost by skipping this parse step.  However, it
    is sometimes necessary for internationalisation to work correctly.
    
    
    ProxyHTMLMeta has two effects.  Firstly and most importantly
    it enables detection of character encodings declared in the form
    
    
    <meta http-equiv="Content-Type" content="text/html;charset=foo">
    
    
    or, in the case of an XHTML document, an XML declaration.
    It is NOT required if the charset is declared in a real HTTP header
    (which is always preferable) from the backend server, nor if the
    document is utf-8 (unicode) or a subset such as ASCII.
    You may also be able to dispense with it where documents use a
    default declared using xml2EncDefault, but that risks propagating an
    incorrect declaration.  A ProxyHTMLCharsetOut
    can remove that risk, but is likely to be a bigger processing
    overhead than enabling ProxyHTMLMeta.
    
    
    The other effect of enabling ProxyHTMLMeta is to parse all
    <meta http-equiv=...> declarations and convert
    them to real HTTP headers, in keeping with the original purpose
    of this form of the HTML <meta> element.
    

    
    Warning
    
      Because ProxyHTMLMeta promotes all
      http-equiv elements to HTTP headers, it is important that you
      only enable it in cases where you trust the HTML content as much as you
      trust the upstream server. If the HTML is controlled by bad actors, it
      will be possible for them to inject arbitrary, possibly malicious, HTTP
      headers into your server's responses.

    ProxyHTMLStripComments Directive
    

    

    Description:Determines whether to strip HTML comments.
    

    Syntax:ProxyHTMLStripComments On|Off
    

    Default:ProxyHTMLStripComments Off
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
for earlier 2.x versions
    

    

    This directive will cause mod_proxy_html to strip HTML comments.
Note that this will also kill off any scripts or styles embedded in
comments (a bogosity introduced in 1995/6 with Netscape 2 for the
benefit of then-older browsers, but still in use today).
It may also interfere with comment-based processors such as SSI or ESI:
be sure to run any of those before mod_proxy_html in the
filter chain if stripping comments!
    


    

    top
    

    ProxyHTMLURLMap Directive
    

    

    Description:Defines a rule to rewrite HTML links
    

    Syntax:ProxyHTMLURLMap from-pattern to-pattern [flags] [cond]
    

    Context:server config, virtual host, directory
    

    Status:Base
    

    Module:mod_proxy_html
    

    Compatibility:Version 2.4 and later; available as a third-party
module for earlier 2.x versions.
    

    

    This is the key directive for rewriting HTML links. When parsing a document,
whenever a link target matches from-pattern, the matching
portion will be rewritten to to-pattern, as modified by any
flags supplied and by the 
ProxyHTMLExtended directive.
Only the elements specified using
the ProxyHTMLLinks directive
will be considered as HTML links.
    


    The optional third argument may define any of the following
Flags.  Flags are case-sensitive.
    

    

    h
    

    Ignore HTML links (pass through unchanged)
    

    e
    

    Ignore scripting events (pass through unchanged)
    

    c
    

    Pass embedded script and style sections through untouched.
    


    L
    

    Last-match.  If this rule matches, no more rules are applied
(note that this happens automatically for HTML links).
    

    l
    

    Opposite to L.  Overrides the one-change-only default
behaviour with HTML links.
    

    R
    

    Use Regular Expression matching-and-replace.  from-pattern
is a regexp, and to-pattern a replacement string that may be
based on the regexp.  Regexp memory is supported: you can use brackets ()
in the from-pattern and retrieve the matches with $1 to $9
in the to-pattern.
    


    If R is not set, it will use string-literal search-and-replace.
The logic is starts-with in HTML links, but
contains in scripting events and embedded script and style sections.

    

    

    x
    

    Use POSIX extended Regular Expressions.  Only applicable with R.
    

    i
    

    Case-insensitive matching.  Only applicable with R.
    


    n
    

    Disable regexp memory (for speed).  Only applicable with R.
    

    s
    

    Line-based regexp matching.  Only applicable with R.
    

    ^
    

    Match at start only.  This applies only to string matching
(not regexps) and is irrelevant to HTML links.
    

    $
    

    Match at end only.  This applies only to string matching
(not regexps) and is irrelevant to HTML links.
    

    V
    

    Interpolate environment variables in to-pattern.
A string of the form ${varname|default} will be replaced by the
value of environment variable varname.  If that is unset, it
is replaced by default.  The |default is optional.
    

    NOTE: interpolation will only be enabled if
ProxyHTMLInterp is On.
    

    


    v
    

    Interpolate environment variables in from-pattern.
Patterns supported are as above.
    

    NOTE: interpolation will only be enabled if
ProxyHTMLInterp is On.
    

    

    


    The optional fourth cond argument defines a condition
that will be evaluated per Request, provided
ProxyHTMLInterp is On.
If the condition evaluates FALSE the map will not be applied in this request.
If TRUE, or if no condition is defined, the map is applied.
    

    A cond is evaluated by the Expression Parser.  In addition, the simpler syntax of conditions
in mod_proxy_html 3.x for HTTPD 2.0 and 2.2 is also supported.

    Summary
    

    
    Warning
    
      
    Form authentication depends on the mod_session
      modules, and these modules make use of HTTP cookies, and as such can fall
      victim to Cross Site Scripting attacks, or expose potentially private
      information to clients. Please ensure that the relevant risks have
      been taken into account before enabling the session functionality on
      your server.
    
    
    

    
    This module allows the use of an HTML login form to restrict access
    by looking up users in the given providers. HTML forms require
    significantly more configuration than the alternatives, however an
    HTML login form can provide a much friendlier experience for end users.
    
    

    
    HTTP basic authentication is provided by
    mod_auth_basic, and HTTP digest authentication is
    provided by mod_auth_digest.  This module should
    be combined with at least one authentication module
    such as mod_authn_file and one authorization
    module such as mod_authz_user.
    

    
    Once the user has been successfully authenticated, the user's login
    details will be stored in a session provided by mod_session.
    
    


    


    top
    

    

    Basic Configuration
    

      
    To protect a particular URL with mod_auth_form, you need to
      decide where you will store your session, and you will need to
      decide what method you will use to authenticate. In this simple example, the
      login details will be stored in a session based on
      mod_session_cookie, and authentication will be attempted against
      a file using mod_authn_file. If authentication is unsuccessful,
      the user will be redirected to the form login page.
    

      
    Basic example
    <Location "/admin">
    AuthFormProvider file
    AuthUserFile "conf/passwd"
    AuthType form
    AuthName "/admin"
    AuthFormLoginRequiredLocation "http://example.com/login.html"

    Session On
    SessionCookieName session path=/

    Require valid-user
</Location>
    

    

      
    The directive AuthType will enable
      the mod_auth_form authentication when set to the value form.
      The directives AuthFormProvider and
      AuthUserFile specify that usernames
      and passwords should be checked against the chosen file.
    

      
    The directives Session and
      SessionCookieName 
      session stored within an HTTP cookie on the browser. For more information
      on the different options for configuring a session, read the documentation for
      mod_session.
    

      
    You can optionally add a 
      SessionCryptoPassphrase to 
      create an encrypted session cookie. This required the additional
      module mod_session_crypto be loaded.
    

      
    In the simple example above, a URL has been protected by
      mod_auth_form, but the user has yet to be given an opportunity to
      enter their username and password. Options for doing so include providing a
      dedicated standalone login page for this purpose, or for providing the login
      page inline.
    
    
    top
    

    

    Standalone Login
    

      
    The login form can be hosted as a standalone page, or can be provided inline on
      the same page.
    

      
    When configuring the login as a standalone page, unsuccessful authentication
      attempts should be redirected to a login form created by the website for this purpose,
      using the AuthFormLoginRequiredLocation
      directive. Typically this login page will contain an HTML form, asking the user to
      provide their usename and password.
    

      
    Example login form
    <form method="POST" action="/dologin.html">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
</form>
    

    

      
    The part that does the actual login is handled by the form-login-handler.
      The action of the form should point at this handler, which is configured within
      Apache httpd as follows:
    

      
    Form login handler example
    <Location "/dologin.html">
    SetHandler form-login-handler
    AuthFormLoginRequiredLocation "http://example.com/login.html"
    AuthFormLoginSuccessLocation "http://example.com/admin/index.html"
    AuthFormProvider file
    AuthUserFile "conf/passwd"
    AuthType form
    AuthName /admin
    Session On
    SessionCookieName session path=/
</Location>
    

    

      
    The URLs specified by the
      AuthFormLoginRequiredLocation directive will typically
      point to a page explaining to the user that their login attempt was unsuccessful, and they
      should try again.  The AuthFormLoginSuccessLocation
      directive specifies the URL the user should be redirected to upon successful login.
    

      
    Alternatively, the URL to redirect the user to on success can be embedded within the login
      form, as in the example below. As a result, the same form-login-handler can be
      reused for different areas of a website.
    

      
    Example login form with location
    <form method="POST" action="/dologin.html">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
  <input type="hidden" name="httpd_location" value="http://example.com/success.html" />
</form>
    

    

    
    top
    

    

    Inline Login
    

      
    Warning
    
        
    A risk exists that under certain circumstances, the login form configured
        using inline login may be submitted more than once, revealing login credentials to
        the application running underneath. The administrator must ensure that the underlying
        application is properly secured to prevent abuse. If in doubt, use the
        standalone login configuration.
    
      
    

      
    As an alternative to having a dedicated login page for a website, it is possible to
      configure mod_auth_form to authenticate users inline, without being
      redirected to another page. This allows the state of the current page to be preserved
      during the login attempt. This can be useful in a situation where a time limited
      session is in force, and the session times out in the middle of the user request. The
      user can be re-authenticated in place, and they can continue where they left off.
    

      
    If a non-authenticated user attempts to access a page protected by
      mod_auth_form that isn't configured with a
      AuthFormLoginRequiredLocation directive,
      a HTTP_UNAUTHORIZED status code is returned to the browser indicating to the user
      that they are not authorized to view the page.
    

      
    To configure inline authentication, the administrator overrides the error document
      returned by the HTTP_UNAUTHORIZED status code with a custom error document
      containing the login form, as follows:
    

      
    Basic inline example
    AuthFormProvider file
ErrorDocument 401 "/login.shtml"
AuthUserFile "conf/passwd"
AuthType form
AuthName realm
AuthFormLoginRequiredLocation "http://example.com/login.html"
Session On
SessionCookieName session path=/
    

    

      
    The error document page should contain a login form with an empty action property,
      as per the example below.  This has the effect of submitting the form to
      the original protected URL, without the page having to know what that
      URL is.
    

      
    Example inline login form
    <form method="POST" action="">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
</form>
    

    

      
    When the end user has filled in their login details, the form will make
      an HTTP POST request to the original password protected URL.
      mod_auth_form will intercept this POST request, and if
      HTML fields are found present for the username and password, the user
      will be logged in, and the original password protected URL will be returned
      to the user as a GET request.
    

    
    top
    

    

    Inline Login with Body Preservation
    

      
    A limitation of the inline login technique described above is that should an
      HTML form POST have resulted in the request to authenticate or
      reauthenticate, the
      contents of the original form posted by the browser will be lost. Depending on
      the function of the website, this could present significant inconvenience for the
      end user.
    

      
    mod_auth_form addresses this by allowing the method and body
      of the original request to be embedded in the login form. If authentication
      is successful, the original method and body will be retried by Apache httpd, preserving
      the state of the original request.
    

      
    To enable body preservation, add three additional fields to the login form as
      per the example below.
    

      
    Example with body preservation
    <form method="POST" action="">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
  
      <input type="hidden" name="httpd_method" value="POST" />
  <input type="hidden" name="httpd_mimetype" value="application/x-www-form-urlencoded" />
  <input type="hidden" name="httpd_body" value="name1=value1&name2=value2" />
    
</form>
    

    

      
    How the method, mimetype and body of the original request are embedded within the
      login form will depend on the platform and technology being used within the website.
      
    

      
    One option is to use the mod_include module along with the
      KeptBodySize directive, along with a suitable
      CGI script to embed the variables in the form.
    

      
    Another option is to render the login form using a CGI script or other dynamic
      technology.
    

      
    CGI example
    AuthFormProvider file
ErrorDocument 401 "/cgi-bin/login.cgi"
...
    

    

    
    top
    

    

    Logging Out
    

      
    To enable a user to log out of a particular session, configure a page to
      be handled by the form-logout-handler. Any attempt to access this
      URL will cause the username and password to be removed from the current
      session, effectively logging the user out.
    

      
    By setting the
      AuthFormLogoutLocation directive,
      a URL can be specified that the browser will be redirected to on successful
      logout. This URL might explain to the user that they have been logged out, and
      give the user the option to log in again.
    

      
    Basic logout example
    SetHandler form-logout-handler
AuthName realm
AuthFormLogoutLocation "http://example.com/loggedout.html"
Session On
SessionCookieName session path=/
    

    

      
    Note that logging a user out does not delete the session; it merely removes
      the username and password from the session. If this results in an empty session,
      the net effect will be the removal of that session, but this is not
      guaranteed. If you want to guarantee the removal of a session, set the
      SessionMaxAge directive to a small
      value, like 1 (setting the directive to zero would mean no session age limit).
      
    

      
    Basic session expiry example
    SetHandler form-logout-handler
AuthFormLogoutLocation "http://example.com/loggedout.html"
Session On
SessionMaxAge 1
SessionCookieName session path=/
    

    

    
    top
    

    

    Usernames and Passwords
    
    
    Note that form submission involves URLEncoding the form data:
    in this case the username and password.  You should therefore
    pick usernames and passwords that avoid characters that are
    URLencoded in form submission, or you may get unexpected results.

    AuthFormAuthoritative Directive
    

    

    Description:Sets whether authorization and authentication are passed to
lower level modules
    

    Syntax:AuthFormAuthoritative On|Off
    

    Default:AuthFormAuthoritative On
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_auth_form
    

    
    
    Normally, each authorization module listed in AuthFormProvider will attempt
    to verify the user, and if the user is not found in any provider,
    access will be denied. Setting the
    AuthFormAuthoritative directive explicitly
    to Off allows for both authentication and
    authorization to be passed on to other non-provider-based modules
    if there is no userID or rule
    matching the supplied userID.  This should only be necessary when
    combining mod_auth_form with third-party modules
    that are not configured with the AuthFormProvider
    directive.  When using such modules, the order of processing
    is determined in the modules' source code and is not configurable.

    AuthFormBody Directive
    

    

    Description:The name of a form field carrying the body of the request to attempt on successful login

    Status:Base
    

    Module:mod_auth_form
    

    Compatibility:Available in Apache HTTP Server 2.3.0 and later
    

    
    
    The AuthFormBody directive specifies
    the name of an HTML field which, if present, will contain the body of the request
    to submit should login be successful.
    

    
    By populating the form with fields described by
    AuthFormMethod,
    AuthFormMimetype and
    AuthFormBody, a website can retry
    a request that may have been interrupted by the login screen, or by a session
    timeout.

    AuthFormDisableNoStore Directive
    

    

    Description:Disable the CacheControl no-store header on the login page

    Status:Base
    

    Module:mod_auth_form
    

    Compatibility:Available in Apache HTTP Server 2.3.0 and later
    

    
    
    The AuthFormDisableNoStore flag
    disables the sending of a Cache-Control no-store header with the
    error 401 page returned when the user is not yet logged in. The purpose of the header
    is to make it difficult for an ecmascript application to attempt to resubmit the
    login form, and reveal the username and password to the backend application. Disable
    at your own risk.

    Module:mod_auth_form
    

    Compatibility:Available in Apache HTTP Server 2.3.0 and later
    

    
    
    The AuthFormFakeBasicAuth flag
    determines whether a Basic Authentication header will be added to
    the request headers. This can be used to expose the username and password to
    an underlying application, without the underlying application having to be aware
    of how the login was achieved.

    By default, if a user is not authorised to view a page, the HTTP response code
    HTTP_UNAUTHORIZED will be returned with the page specified by the
    ErrorDocument directive. This directive overrides this
    default.
    

    
    Use this directive if you have a dedicated login page to redirect users to.

    This directive can be overridden if a form field has been defined containing another URL
    using the AuthFormLocation directive.

    The AuthFormLogoutLocation directive
    specifies the URL of a page on the server to redirect to should the user attempt to log
    out. The value is parsed using the ap_expr parser before
    being sent to the client.
    

    
    When a URI is accessed that is served by the handler form-logout-handler,
    the page specified by this directive will be shown to the end user. For example:
    

    
    Example
    <Location "/logout">
    SetHandler form-logout-handler
    AuthFormLogoutLocation "http://example.com/loggedout.html"
    Session on
    #...
</Location>
    

    

    
    An attempt to access the URI /logout/ will result in the user being logged
    out, and the page /loggedout.html will be displayed. Make sure that the page
    loggedout.html is not password protected, otherwise the page will not be

    The AuthFormProvider directive sets
    which provider is used to authenticate the users for this location.
    The default file provider is implemented
    by the mod_authn_file module.  Make sure
    that the chosen provider module is present in the server.
    

    
    Example
    <Location "/secure">
    AuthType form
    AuthName "private area"
    AuthFormProvider  dbm
    AuthDBMType        SDBM
    AuthDBMUserFile    "/www/etc/dbmpasswd"
    Require            valid-user
    #...
</Location>
    

    

    
    Providers are implemented by mod_authn_dbm,
    mod_authn_file, mod_authn_dbd,
    mod_authnz_ldap and mod_authn_socache.

    Compatibility:Available in Apache HTTP Server 2.3.0 and later
    

    
    
    The AuthFormSitePassphrase directive
    specifies a passphrase which, if present in the user session, causes Apache httpd to
    bypass authentication checks for the given URL. It can be used on high traffic websites
    to reduce the load induced on authentication infrastructure.
    

    
    The passphrase can be inserted into a user session by adding this directive to the
    configuration for the form-login-handler. The form-login-handler
    itself will always run the authentication checks, regardless of whether a passphrase
    is specified or not.
    

    
    Warning
    
      
    If the session is exposed to the user through the use of
      mod_session_cookie, and the session is not protected with
      mod_session_crypto, the passphrase is open to potential exposure
      through a dictionary attack. Regardless of how the session is configured,
      ensure that this directive is not used within URL spaces where private user data
      could be exposed, or sensitive transactions can be conducted. Use at own risk.

    Syntax:AuthFormSize size
    

    Default:AuthFormSize 8192
    

    Context:directory
    

    Status:Base
    

    Module:mod_auth_form
    

    Compatibility:Available in Apache HTTP Server 2.3.0 and later
    

    
    
    The AuthFormSize directive specifies
    the maximum size of the body of the request that will be parsed to find the login form.
    

    
    If a login request arrives that exceeds this size, the whole request will be aborted
    with the HTTP response code HTTP_REQUEST_TOO_LARGE.
    

    
    If you have populated the form with fields described by
    AuthFormMethod,
    AuthFormMimetype and
    AuthFormBody, you probably want to set this
    field to a similar size as the KeptBodySize
    directive.

    Description:Autorisations de groupe à base de nom d'hôte (nom ou
adresse IP)

    Identificateur de Module:access_compat_module
    

    Fichier Source:mod_access_compat.c
    

    Compatibilité:Disponible dans la version 2.3 du serveur HTTP Apache
à des fins de compatibilité
avec les précédentes versions d'Apache httpd 2.x. Les directives fournies par
ce module sont devenues obsolètes depuis la refonte d'authz. Voir
mod_authz_host
    

    Sommaire
    

    
    Les directives fournies par le module
    mod_access_compat s'utilisent dans les sections
    <Directory>,
    <Files> et
    <Location>, ainsi
    que dans les fichiers .htaccess et permettent
    de contrôler l'accès à certaines parties du serveur. On peut
    contrôler cet accès en fonction du nom d'hôte du client, de son
    adresse IP ou d'autres caractéristiques de la requête, telles
    qu'elles sont enregistrées dans les variables
    d'environnement. Les directives Allow et Deny permettent de spécifier
    quels clients sont ou ne sont pas autorisés à accéder au serveur,
    alors que la directive Order définit le statut
    d'accès par défaut, et détermine la manière dont les directives
    Allow et
    Deny interagissent
    entre elles.
    

    
    Les restrictions d'accès à base de nom d'hôte et
    l'authentification à base de mot de passe peuvent être implémentées
    simultanément. Dans ce cas, on utilise la directive Satisfy pour déterminer la
    manière dont ces deux modes de restrictions interagissent.
    

    
    Note
    
      
    Les directives fournies par le module
      mod_access_compat sont devenues obsolètes depuis
      la refonte du module mod_authz_host. Mélanger d'anciennes
      directives comme Order, Allow ou Deny avec des nouvelles comme
      Require est techniquement
      possible mais déconseillé. En effet, mod_access_compat a
      été conçu pour supporter des configurations ne contenant que des anciennes
      directives afin de faciliter le passage à la version 2.4. Voir le document
      upgrading pour plus de détails.
      
    
    
    

    
    En général, les directives de restriction d'accès s'appliquent à
    toutes les méthodes d'accès (GET, PUT,
    POST, etc...). C'est d'ailleurs ce que l'on souhaite
    dans la plupart des cas. Il est cependant possible de restreindre
    certaines méthodes, alors que les autres méthodes ne se verront
    imposée aucune restriction, en regroupant les directives à
    l'intérieur d'une section <Limit>.
    

    
    Fusion des sections de configuration
    
      
    Lorsqu'une directive fournie par ce module est utilisée dans
      une nouvelle section de configuration, cette dernière n'hérite
      d'aucune directive définie dans une section précédente.

    Directive Allow
    

    

    Description:Spécifie quels hôtes peuvent accéder à une certaine zone du
serveur
    

    Syntaxe: Allow from all|hôte|env=[!]variable
d'environnement
[hôte|env=[!]variable d'environnement] ...
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:Limit
    

    Statut:Extension
    

    Module:mod_access_compat
    

    
    
    La directive Allow permet de définir quels
    hôtes ont le droit d'accéder à une certaine partie du serveur. On
    peut contrôler l'accès par nom d'hôte, adresse IP, intervalle
    d'adresses IP, ou toute autre caractéristique de la requête client
    enregistrée dans les variables d'environnement.
    

    
    Le premier argument de cette directive est toujours
    from. Les arguments suivants peuvent prendre trois
    formes différentes. Si Allow from all est spécifié,
    tout hôte se voit accordé l'accès, en tenant compte des directives
    Deny et Order comme décrit plus loin.
    Pour ne permettre l'accès au serveur qu'à un hôte ou un groupe
    d'hôtes particuliers, on peut spécifier un nom d'hôte sous
    une des formes suivantes :
    

    
    
      
    Un nom de domaine (partiel)
    

      
    
      
    Allow from example.org
Allow from .net example.edu
    

      
    Les hôtes dont les noms correspondent ou se terminent par la
      chaîne spécifiée ont l'autorisation d'accès. Seules les
      composantes entières du nom d'hôte doivent correspondre ; ainsi,
      dans l'exemple ci-dessus, foo.example.org
      correspondra, mais fooexample.org ne conviendra pas.
      Avec cette configuration, Apache httpd va effectuer une double recherche
      DNS sur l'adresse IP du client, sans tenir compte de la
      définition de la directive HostnameLookups. Tout d'abord, une
      recherche DNS inverse sur l'adresse IP est effectuée pour
      déterminer le nom d'hôte associé, puis une recherche directe sur
      le nom d'hôte est effectuée afin de s'assurer qu'il correspond
      bien à l'adresse IP originale. L'accès ne sera accordé que si le
      nom d'hôte correspond et si les recherches DNS inverse et directe
      concordent.
    

      
    Une adresse IP complète
    

      
    
      
    Allow from 10.1.2.3
Allow from 192.168.1.104 192.168.1.205
    

      
    L'adresse IP d'un hôte auquel on a accordé l'accès
    

      
    Une adresse IP partielle
    

      
    
      
    Allow from 10.1
Allow from 10 172.20 192.168.2
    

      
    De un à trois des premiers octets d'une adresse IP, afin de
      restreindre l'accès à un sous-réseau.
    

      
    Une paire réseau/masque de sous-réseau
    

      
    
      
    Allow from 10.1.0.0/255.255.0.0
    

      
    Un réseau a.b.c.d, et un masque de sous-réseau w.x.y.z, pour
      une définition plus précise de la restriction d'accès imposée à un
      sous-réseau.
    

      
    Une spécification CIDR réseau/nnn
    

      
    
      
    Allow from 10.1.0.0/16
    

      
    Identique au cas précédent, mis à part que le masque est
      constitué des nnn bits de poids fort.
    
    
    

    
    Notez que les trois derniers exemples désignent le même ensemble
    d'hôtes.
    

    
    On peut spécifier des adresses et sous-réseaux IPv6 de la manière
    suivante :
    

    
    Allow from 2001:db8::a00:20ff:fea7:ccea
Allow from 2001:db8::a00:20ff:fea7:ccea/10
    


    
    Le troisième format d'argument de la directive
    Allow permet de contrôler l'accès au serveur
    en fonction de l'existence d'une variable d'environnement. Lorsque Allow
    from env=variable d'environnement est spécifié, la
    requête est autorisée si la variable d'environnement variable
    d'environnement existe. En revanche, lorsque Allow from
    env=!env-variable est spécifié, la
    requête est autorisée si la variable d'environnement variable
    d'environnement n'existe pas. Le serveur permet de définir
    avec souplesse des variables d'environnement en se basant sur les
    caractéristiques de la requête client et en utilisant les directives
    fournies par le module mod_setenvif. Ainsi, on peut
    utiliser la directive Allow pour permettre
    l'accès en fonction de paramètres comme le User-Agent
    (type de navigateur) des clients, le Referer, ou
    d'autres champs d'en-tête de la requête HTTP.
    

    
    SetEnvIf User-Agent ^KnockKnock/2\.0 let_me_in
<Directory "/docroot">
    Order Deny,Allow
    Deny from all
    Allow from env=let_me_in
</Directory>
    


    
    Dans cet exemple, les navigateurs dont la chaîne user-agent
    commence par KnockKnock/2.0 se verront accorder
    l'accès, alors que tous les autres seront rejetés.
    

    
    Fusion des sections de configuration
    
      
    Lorsqu'une directive fournie par ce module est utilisée dans
      une nouvelle section de configuration, cette dernière n'hérite
      d'aucune directive définie dans une section précédente.

    Directive Deny
    

    

    Description:Définit quels hôtes ne sont pas autorisés à accéder au
serveur
    

    Syntaxe: Deny from all|hôte|env=[!]variable
d'environnement
[hôte|env=[!]variable d'environnement] ...

    Surcharges autorisées:Limit
    

    Statut:Extension
    

    Module:mod_access_compat
    

    
    
    Cette directive permet de restreindre l'accès au serveur en
    fonction du nom d'hôte, de l'adresse IP ou de variables
    d'environnement. Les arguments de la directive
    Deny sont identiques aux arguments de la
    directive Allow.
    


    

    top
    

    Directive Order
    

    

    Description:Définit le statut d'accès par défaut et l'ordre dans lequel
les directives Allow et
Deny sont évaluées.
    

    Syntaxe: Order ordre
    

    Défaut:Order Deny,Allow
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:Limit
    

    Statut:Extension
    

    Module:mod_access_compat
    

    

    
    La directive Order, associée aux
    directives Allow
    et Deny,
    implémente un système de contrôle d'accès en trois passes. Au cours
    de la première passe, ce sont soit toutes les directives Allow, soit toutes les
    directives Deny qui sont traitées, selon
    la définition de la directive Order. Le reste des
    directives (Deny
    ou Allow) est
    traité au cours de la seconde passe. La troisième passe s'applique à
    toutes les requêtes qui ne sont concernées par aucune des deux
    premières passes.
    

    
    Notez que toutes les directives Allow et Deny sont traitées, à la
    différence d'un pare-feu classique où seule la première règle qui
    correspond est utilisée. La dernière directive qui correspond
    s'applique ( à la différence là encore d'un pare-feu classique). De
    plus, l'ordre dans lequel les lignes apparaissent dans le fichier de
    configuration n'a pas d'incidence -- toutes les lignes Allow sont considérées comme
    un groupe, toutes les lignes Deny comme un autre, et le
    statut par défaut a son existence propre.
    

    
    Ordre peut être :
    

    
    
      
    Allow,Deny
    

      
    Dans un premier temps, toutes les directives Allow sont évaluées ; au
      moins une d'entre elles doit correspondre, sinon la requête est
      rejetée. Ensuite, toutes les directives Deny sont évaluées. Si au
      moins l'une d'entre elles correspond, la requête est rejetée.
      Enfin, toute requête qui ne correspond à aucune directive
      Allow ou
      Deny est rejetée
      par défaut.
    

      
    Deny,Allow
    

      
    Dans un premier temps, toutes les directives Deny sont évaluées ; Si au
      moins une d'entre elles correspond, la requête est rejetée,
      à moins qu'elle corresponde aussi à une directive
      Allow. Toute
      requête qui ne correspond à aucune directive Allow ou Deny est autorisée.
    

      
    Mutual-failure
    

      
    Cet argument a le même effet que Allow,Deny et
      est devenu de ce fait obsolète.
    
    
    

    
    Les mots-clés ne peuvent être séparés que par des virgules ;
    aucun espace ne doit s'intercaler entre eux.

        La dernière correspondance l'emporte : autorisation
      
    
    
    

    
    Dans cet exemple, tous les hôtes du domaine example.org ont
    l'autorisation d'accès ; tous les autres voient leur accès
    refusé.
    

    
    Order Deny,Allow
Deny from all
Allow from example.org
    


    
    Dans l'exemple suivant, tous les hôtes du domaine example.org ont
    l'autorisation d'accès, sauf ceux du sous-domaine foo.example.org qui
    voient leur accès refusé. Tous les hôtes qui ne sont pas dans le
    domaine example.org sont rejetés car le statut par défaut est positionné
    sur Deny, et consiste donc en un
    refus d'accès.
    

    
    Order Allow,Deny
Allow from example.org
Deny from foo.example.org
    


    
    Par contre, si la valeur de la directive
    Order, dans l'exemple précédent, est
    Deny,Allow, tout le monde a l'autorisation d'accès.
    Ceci est dû au fait que Allow from example.org sera
    évalué en dernier, sans tenir compte de l'ordre réel dans lequel les
    directives apparaissent dans le fichier de configuration, et va
    l'emporter sur Deny from foo.example.org. Tout hôte qui
    n'est pas dans le domaine example.org aura aussi
    l'autorisation d'accès car le statut par défaut est positionné sur
    Allow et constitue donc une
    autorisation d'accès.
    

    
    La présence d'une directive Order peut
    affecter le contrôle d'accès à une partie du serveur même en
    l'abscence de directives Allow et Deny associées, à cause de
    son influence sur le statut par défaut. Par exemple,
    

    
    <Directory "/www">
    Order Allow,Deny
</Directory>
    


    
    va interdire tout accès au répertoire /www à cause
    du statut d'accès par défaut qui est défini à Deny.
    

    
    La directive Order ne contrôle l'ordre
    dans lequel sont traitées les directives d'accès qu'au cours de
    chaque phase du traitement de la configuration du serveur. Ceci
    implique, par exemple, qu'une directive Allow ou Deny située dans une section
    <Location> sera
    toujours évaluée après une directive Allow ou Deny située dans une section
    <Directory> ou un
    fichier .htaccess, sans tenir compte de la
    définition de la directive Order. Pour plus
    de détails à propos de la fusion des sections de configuration, voir
    le document Comment fonctionnent les sections Directory,
    Location et Files.

      une nouvelle section de configuration, cette dernière n'hérite
      d'aucune directive définie dans une section précédente.

    Directive Satisfy
    

    

    Description:Interaction entre le contrôle d'accès en fonction de l'hôte
et l'authentification utilisateur
    

    Syntaxe:Satisfy Any|All
    

    Défaut:Satisfy All
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_access_compat
    

    Compatibilité:Affecté par <Limit> et <LimitExcept> à partir de la version
2.0.51
    

    
    
    Politique d'accès dans le cas où on utilise à la fois Allow et Require. L'argument est soit
    All, soit Any. L'utilisation de cette
    directive n'a de sens que si l'accès à une zone particulière du
    serveur est restreinte par utilisateur/mot de passe et en fonction
    de l'adresse IP de l'hôte client. Dans ce cas, par
    défaut (All), le client doit satisfaire à la
    restriction d'adresse, et fournir un couple
    utilisateur/mot de passe valide. Avec l'argument Any,
    le client se verra accorder l'accès s'il satisfait à la restriction
    d'adresse ou fournit un couple utilisateur/mot de passe valide. On
    peut utiliser cette dernière définition pour restreindre l'accès à
    une zone par mot de passe, mais accorder l'accès aux clients
    possédant certaines adresses IP sans qu'ils aient à fournir de mot
    de passe.
    

    
    Par exemple, si vous souhaitez que les utilisateurs de votre
    réseau accèdent à une zone de votre site web sans restriction, mais
    que l'accès à cette zone nécessite un mot de passe pour les autres
    utilisateurs, vous pouvez utiliser une configuration du style :
    

    
    Require valid-user
Allow from 192.168.1
Satisfy Any
    


    
    
    Une autre utilisation fréquente de la directive
    Satisfy est l'allègement des restrictions
    d'accès à un sous-répertoire par rapport aux restrictions d'accès au
    répertoire parent :
    
    

    
    <Directory "/var/www/private">
    Require valid-user
</Directory>

<Directory "/var/www/private/public">
    Allow from all
    Satisfy Any
</Directory>
    


    
    Dans l'exemple ci-dessus, l'accès au répertoire
    /var/www/private nécessitera une authentification,
    alors que l'accès au répertoire /var/www/private/public
    sera accordé sans restriction.
    


    
    Depuis la version 2.0.51, les directives
    Satisfy peuvent être restreintes à certaines
    méthodes particulières à l'aide des sections <Limit> et <LimitExcept>.
    

    
    Fusion des sections de configuration
    
      
    Lorsqu'une directive fournie par ce module est utilisée dans
      une nouvelle section de configuration, cette dernière n'hérite
      d'aucune directive définie dans une section précédente.

    Description:Server-parsed html documents (Server Side Includes)
    

    Status:Base
    

    Module Identifier:include_module
    

    Source File:mod_include.c
    

    Summary
    

    
    This module provides a filter which will process files
    before they are sent to the client. The processing is
    controlled by specially formatted SGML comments, referred to as
    elements. These elements allow conditional text, the
    inclusion of other files or programs, as well as the setting and
    printing of environment variables.
    

    


    top
    

    

    Enabling Server-Side Includes
    
    

    
    Server Side Includes are implemented by the
    INCLUDES filter. If
    documents containing server-side include directives are given
    the extension .shtml, the following directives will make Apache
    parse them and assign the resulting document the mime type of
    text/html:
    

    
    AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
    


    
    The following directive must be given for the directories
    containing the shtml files (typically in a
    <Directory> section,
    but this directive is also valid in .htaccess files if
    AllowOverride Options
    is set):
    

    
    Options +Includes
    


    
    For backwards compatibility, the server-parsed
    handler also activates the
    INCLUDES filter. As well, Apache will activate the INCLUDES
    filter for any document with mime type
    text/x-server-parsed-html or
    text/x-server-parsed-html3 (and the resulting
    output will have the mime type text/html).
    

    
    For more information, see our Tutorial on Server Side Includes.
    

    top
    

    

    PATH_INFO with Server Side Includes
    
    

    
    Files processed for server-side includes no longer accept
    requests with PATH_INFO (trailing pathname information)
    by default.  You can use the AcceptPathInfo directive to
    configure the server to accept requests with PATH_INFO.
    

    top
    

    

    Available Elements
    
    
    The document is parsed as an HTML document, with special
    commands embedded as SGML comments. A command has the syntax: 
    

    
    
      <!--#element attribute=value
      attribute=value ... -->
    
    

    
    The value will often be enclosed in double quotes, but single
    quotes (') and backticks (`) are also
    possible. Many commands only allow a single attribute-value pair.
    Note that the comment terminator (-->) should be
    preceded by whitespace to ensure that it isn't considered part of
    an SSI token. Note that the leading <!--# is one
    token and may not contain any whitespaces.
    

    
    The allowed elements are listed in the following table:
    

    
    
    
    ElementDescription
    
    
    comment
        SSI comment
    
    
    config
        configure output formats
    
    
    echo
        print variables
    
    
    exec
        execute external programs
    
    
    fsize
        print size of a file
    
    
    flastmod
        print last modification time of a file
    
    
    include
        include a file
    
    
    printenv
        print all available variables
    
    
    set
        set a value of a variable
    
    
    

    
    SSI elements may be defined by modules other than
    mod_include. In fact, the exec element is provided by
    mod_cgi, and will only be available if this
    module is loaded.
    

    
    The comment Element
    
      
    This command doesn't output anything. Its only use is to
      add comments within a file. These comments are not printed.
    

      
    This syntax is available in version 2.4.21 and later.
    

      
    
      <!--#comment Blah Blah Blah -->
    
         or
    
      <!--#comment text="Blah Blah Blah" -->
      
    
     

    
    The config Element
    
      
    This command controls various aspects of the parsing. The
      valid attributes are:
    

      
    
      
    echomsg (Apache 2.1 and later)
    
      
    The value is a message that is sent back to the
      client if the echo element
      attempts to echo an undefined variable. This overrides any SSIUndefinedEcho directives.
    

      
    
        <!--#config echomsg="[Value Undefined]" -->
      
    
      
    

      
    errmsg
    
      
    The value is a message that is sent back to the
      client if an error occurs while parsing the
      document. This overrides any SSIErrorMsg directives.
    

      
    
       <!--#config errmsg="[Oops, something broke.]" -->
      
    
      
    

      
    sizefmt
    
      
    The value sets the format to be used when displaying
      the size of a file. Valid values are bytes
      for a count in bytes, or abbrev for a count
      in Kb or Mb as appropriate, for example a size of 1024 bytes
      will be printed as "1K".
    

      
    
      <!--#config sizefmt="abbrev" -->
      
    

      
    

      
    timefmt
    
      
    The value is a string to be used by the
      strftime(3) library routine when printing
      dates.
    

      
    
      <!--#config timefmt=""%R, %B %d, %Y"" -->
      
    

      
    
      
    
     

    
    The echo Element
    
      
    This command prints one of the include
      variables defined below. If the variable is unset, the result is
      determined by the SSIUndefinedEcho directive. Any dates printed are
      subject to the currently configured timefmt.
    

      
    Attributes:
    

      
    
      
    var
    
      
    The value is the name of the variable to print.
    

      
    decoding
    
      
    Specifies whether Apache should strip an encoding from
      the variable before processing the variable further. The default
      is none, where no decoding will be done. If set to
      url, then URL decoding (also known as %-encoding;
      this is appropriate for use within URLs in links, etc.) will be
      performed. If set to urlencoded,
      application/x-www-form-urlencoded compatible encoding (found in
      query strings) will be stripped. If set to base64,
      base64 will be decoded, and if set to entity, HTML
      entity encoding will be stripped. Decoding is done prior to any
      further encoding on the variable. Multiple encodings can be
      stripped by specifying more than one comma separated encoding.
      The decoding setting will remain in effect until the next decoding
      attribute is encountered, or the element ends.
    

      
    The decoding attribute must precede the
      corresponding var attribute to be effective.
    
      
    

      
    encoding
    
      
    Specifies how Apache should encode special characters
      contained in the variable before outputting them. If set
      to none, no encoding will be done. If set to
      url, then URL encoding (also known as %-encoding;
      this is appropriate for use within URLs in links, etc.) will be
      performed. If set to urlencoded,
      application/x-www-form-urlencoded compatible encoding will be
      performed instead, and should be used with query strings. If set
      to base64, base64 encoding will be performed. At
      the start of an echo element, the default is set to
      entity, resulting in entity encoding (which is
      appropriate in the context of a block-level HTML element,
      e.g. a paragraph of text). This can be changed by adding
      an encoding attribute, which will remain in effect
      until the next encoding attribute is encountered or
      the element ends, whichever comes first.
    

      
    The encoding attribute must precede the
      corresponding var attribute to be effective.
    

      
    
        In order to avoid cross-site scripting issues, you should
        always encode user supplied data.
      
    

      
    Example
    
        <!--#echo encoding="entity" var="QUERY_STRING" -->
      
    
      
    
      
    
     

    
    The exec Element
    
      
    The exec command executes a given shell command or
      CGI script. It requires mod_cgi to be present
      in the server. If Options
      IncludesNOEXEC is set, this command is completely
      disabled. The valid attributes are:
    

      
    
      
    cgi
    
      
    The value specifies a (%-encoded) URL-path to
      the CGI script. If the path does not begin with a slash (/),
      then it is taken to be relative to the current
      document. The document referenced by this path is
      invoked as a CGI script, even if the server would not
      normally recognize it as such. However, the directory
      containing the script must be enabled for CGI scripts
      (with ScriptAlias
      or Options
      ExecCGI).
    

      
    The CGI script is given the PATH_INFO and query
      string (QUERY_STRING) of the original request from the
      client; these cannot be specified in the URL path. The
      include variables will be available to the script in addition to
      the standard CGI environment.
    

      
    Example
    
        <!--#exec cgi="/cgi-bin/example.cgi" -->
      
    

      
    If the script returns a Location: header instead of
      output, then this will be translated into an HTML anchor.
    

      
    The include virtual
      element should be used in preference to exec cgi. In
      particular, if you need to pass additional arguments to a CGI program,
      using the query string, this cannot be done with exec
      cgi, but can be done with include virtual, as
      shown here:
    

      
    
        <!--#include virtual="/cgi-bin/example.cgi?argument=value" -->
      
    
      
    

      
    cmd
    
      
    The server will execute the given string using
      /bin/sh. The include variables are available to the command, in addition
      to the usual set of CGI variables.
    

      
    The use of #include virtual is almost always preferred to using
      either #exec cgi or #exec cmd. The former
      (#include virtual) uses the standard Apache sub-request
      mechanism to include files or scripts. It is much better tested and
      maintained.
    

      
    In addition, on some platforms, like Win32, and on unix when
      using suexec, you cannot pass arguments
      to a command in an exec directive, or otherwise include
      spaces in the command. Thus, while the following will work under a
      non-suexec configuration on unix, it will not produce the desired
      result under Win32, or when running suexec:
    

      
    
        <!--#exec cmd="perl /path/to/perlscript arg1 arg2" -->
      
    
      
    
      
    
     

    
    The fsize Element
    
      
    This command prints the size of the specified file, subject
      to the sizefmt format specification. Attributes:
    

      
    
      
    file
    
      
    The value is a path relative to the directory
      containing the current document being parsed.

    
    
        This file is <!--#fsize file="mod_include.html" --> bytes.
    
    

    The value of file cannot start with a slash
    (/), nor can it contain ../ so as to
    refer to a file above the current directory or outside of the
    document root. Attempting to so will result in the error message:
    The given path was above the root path.
      
    

      
    virtual
    
      
    The value is a (%-encoded) URL-path. If it does not begin with
      a slash (/) then it is taken to be relative to the current document.
      Note, that this does not print the size of any CGI output,
      but the size of the CGI script itself.
    
      
    

    
    
        This file is <!--#fsize virtual="/docs/mod/mod_include.html" --> bytes.
    
    

      
    Note that in many cases these two are exactly the same thing.
      However, the file attribute doesn't respect URL-space
      aliases.
    
     

    
    The flastmod Element
    
      
    This command prints the last modification date of the
      specified file, subject to the timefmt format
      specification. The attributes are the same as for the
      fsize command.
    
     

    
    The include Element
    
      
    This command inserts the text of another document or file
      into the parsed file. Any included file is subject to the usual
      access control. If the directory containing the parsed file has
      Options
      IncludesNOEXEC set, then only documents with a text
      MIME-type (text/plain,
      text/html etc.) will be included. Otherwise CGI
      scripts are invoked as normal using the complete URL given in
      the command, including any query string.
    

      
    An attribute defines the location of the document, and may
      appear more than once in an include element; an inclusion is
      done for each attribute given to the include command in turn.
      The valid attributes are:
    

      
    
      
    file
    
      
    The value is a path relative to the directory
      containing the current document being parsed. It cannot
      contain ../, nor can it be an absolute path.
      Therefore, you cannot include files that are outside of the
      document root, or above the current document in the directory
      structure. The virtual attribute should always be
      used in preference to this one.
    

      
    virtual
    
      
    The value is a (%-encoded) URL-path. The URL cannot contain a
      scheme or hostname, only a path and an optional query string. If it
      does not begin with a slash (/) then it is taken to be relative to the
      current document.
    

      
    A URL is constructed from the attribute, and the output the
      server would return if the URL were accessed by the client is
      included in the parsed output. Thus included files can be nested.
    

      
    If the specified URL is a CGI program, the program will be
      executed and its output inserted in place of the directive in the
      parsed file. You may include a query string in a CGI url:
    

      
    
        <!--#include virtual="/cgi-bin/example.cgi?argument=value" -->
      
    

      
    include virtual should be used in preference
      to exec cgi to include the output of CGI programs
      into an HTML document.
    

      
    If the KeptBodySize
      directive is correctly configured and valid for this included
      file, attempts to POST requests to the enclosing HTML document
      will be passed through to subrequests as POST requests as well.
      Without the directive, all subrequests are processed as GET
      requests.
    

      
    

      
    onerror
    
      
    The value is a (%-encoded) URL-path which is shown should a
      previous attempt to include a file or virtual attribute failed.
      To be effective, this attribute must be specified after the
      file or virtual attributes being covered. If the attempt to
      include the onerror path fails, or if onerror is not specified, the
      default error message will be included.
    

      
    
        # Simple example
    
        <!--#include virtual="/not-exist.html" onerror="/error.html" -->
      
    

      
    
        # Dedicated onerror paths
    
        <!--#include virtual="/path-a.html" onerror="/error-a.html" virtual="/path-b.html" onerror="/error-b.html" -->
      
    

      
    
      
    
     

    
    The printenv Element
    
      
    This prints out a plain text listing of all existing variables and
      their values. Special characters are entity encoded (see the echo element for details)
      before being output. There are no attributes.
    

      
    Example
    
        <pre>
          <!--#printenv -->
        </pre>
      
    
     

    
    The set Element
    
      
    This sets the value of a variable. Attributes:
    

      
    
      
    var
    
      
    The name of the variable to set.
    

      
    value
    
      
    The value to give a variable.
    

      
    decoding
    
      
    Specifies whether Apache should strip an encoding from
      the variable before processing the variable further. The default
      is none, where no decoding will be done. If set to
      url, urlencoded, base64
      or entity, URL decoding,
      application/x-www-form-urlencoded decoding, base64 decoding or HTML
      entity decoding will be performed respectively. More than one
      decoding can be specified by separating with commas. The decoding
      setting will remain in effect until the next decoding attribute
      is encountered, or the element ends. The decoding
      attribute must precede the corresponding
      var attribute to be effective.
    
      
    

      
    encoding
    
      
    Specifies how Apache should encode special characters
      contained in the variable before setting them. The default is
      none, where no encoding will be done. If set to
      url, urlencoding, base64
      or entity, URL encoding,
      application/x-www-form-urlencoded encoding, base64 encoding or
      HTML entity encoding will be performed respectively. More than
      one encoding can be specified by separating with commas. The
      encoding setting will remain in effect until the next encoding
      attribute is encountered, or the element ends. The
      encoding attribute must precede the
      corresponding var attribute to be effective.
      Encodings are applied after all decodings have been
      stripped.

    Include Variables
    
    

    
    In addition to the variables in the standard CGI environment,
    these are available for the echo command, for
    if and elif, and to any program
    invoked by the document.
    

    
    
      
    DATE_GMT
    
      
    The current date in Greenwich Mean Time.
    

      
    DATE_LOCAL
    
      
    The current date in the local time zone.
    

      
    DOCUMENT_ARGS
    
      
    This variable contains the query string of the active SSI
      document, or the empty string if a query string is not
      included.  For subrequests invoked through the
      include SSI directive, QUERY_STRING
      will represent the query string of the subrequest and
      DOCUMENT_ARGS will represent the query string of
      the SSI document.  (Available in Apache HTTP Server 2.4.19 and
      later.)
    

      
    DOCUMENT_NAME
    
      
    The filename (excluding directories) of the document
      requested by the user.
    

      
    DOCUMENT_PATH_INFO
    
      
    The trailing pathname information. See directive AcceptPathInfo for more information
      about PATH_INFO.
    

      
    DOCUMENT_URI
    
      
    The (%-decoded) URL path of the document requested by the
      user. Note that in the case of nested include files, this is
      not the URL for the current document.  Note also that
      if the URL is modified internally (e.g. by an alias or directoryindex), the modified
      URL is shown.
    

      
    LAST_MODIFIED
    
      
    The last modification date of the document requested by
      the user.
    

      
    QUERY_STRING_UNESCAPED
    
      
    If a query string is present in the request for the active
      SSI document, this variable contains the (%-decoded) query
      string, which is escaped for shell usage (special
      characters like & etc. are preceded by
      backslashes).  It is not set if a query string is not
      present.  Use DOCUMENT_ARGS if shell escaping
      is not desired.
    

      
    USER_NAME
    
      
    The user name of the owner of the file.
    
    
    

    top
    

    

    Variable Substitution
    

    
    Variable substitution is done within quoted strings in most
    cases where they may reasonably occur as an argument to an SSI
    directive. This includes the config,
    exec, flastmod, fsize,
    include, echo, and set
    directives. If SSILegacyExprParser is set to on,
    substitution also occurs in the arguments to conditional operators.
    You can insert a literal dollar sign into the string using backslash
    quoting:
    

    
    
      <!--#set var="cur" value="\$test" -->
    
    

    
    If a variable reference needs to be substituted in the
    middle of a character sequence that might otherwise be
    considered a valid identifier in its own right, it can be
    disambiguated by enclosing the reference in braces,
    a la shell substitution:
    

    
    
      <!--#set var="Zed" value="${REMOTE_HOST}_${REQUEST_METHOD}" -->
    
    

    
    This will result in the Zed variable being set
    to "X_Y" if REMOTE_HOST is
    "X" and REQUEST_METHOD is
    "Y".
    

    top
    

    

    Flow Control Elements
    
    

    
    The basic flow control elements are:
    

    
    
      <!--#if expr="test_condition" -->
    
      <!--#elif expr="test_condition" -->
    
      <!--#else -->
    
      <!--#endif -->
    
    

    
    The if element works like an if statement in a
    programming language. The test condition is evaluated and if
    the result is true, then the text until the next elif,
    else or endif element is included in the
    output stream.
    

    
    The elif or else statements are used
    to put text into the output stream if the original
    test_condition was false. These elements are optional.
    

    
    The endif element ends the if element
    and is required.
    

    
    test_condition is a boolean expression which follows the
    ap_expr syntax. The syntax can be changed
    to be compatible with Apache HTTPD 2.2.x using SSILegacyExprParser.
    

    
    The SSI variables set with the var element are exported
    into the request environment and can be accessed with the
    reqenv function. As a short-cut, the function name
    v is also available inside mod_include.
    

    
    The below example will print "from local net" if client IP address
    belongs to the 10.0.0.0/8 subnet.
    

    
    
      <!--#if expr='-R "10.0.0.0/8"' -->
    
      
        from local net
    
          
      <!--#else -->
    
      
        from somewhere else
    
          
      <!--#endif -->
    
    

    
    The below example will print "foo is bar" if the variable
    foo is set to the value "bar".
    

    
    
      <!--#if expr='v("foo") = "bar"' -->
    
      
        foo is bar
    
          
      <!--#endif -->
    
    

    
    Reference Documentation
    
    
    See also: Expressions in Apache HTTP Server,
    for a complete reference and examples. The restricted functions
    are not available inside mod_include

    Legacy expression syntax
    
    

    
    This section describes the syntax of the #if expr
    element if SSILegacyExprParser
    is set to on.
    

    
    
      
    string
    
      
    true if string is not empty
    

      
    -A string
    
      
    true if the URL represented by the string is accessible by
      configuration, false otherwise. This is useful where content on a
      page is to be hidden from users who are not authorized to view the
      URL, such as a link to that URL. Note that the URL is only tested
      for whether access would be granted, not whether the URL exists.
    

      
    Example
    
        <!--#if expr="-A /private" -->
    
        
          Click <a href="/private">here</a> to access private
          information.
    
            
        <!--#endif -->
      
    
      
    

      
    string1 = string2
    
      string1 == string2
    
      string1 != string2
    

      
    Compare string1 with string2. If
      string2 has the form /string2/
      then it is treated as a regular expression. Regular expressions are
      implemented by the PCRE engine and
      have the same syntax as those in perl
      5. Note that == is just an alias for =
      and behaves exactly the same way.
    

      
    If you are matching positive (= or ==), you
      can capture grouped parts of the regular expression. The captured parts
      are stored in the special variables $1 ..
      $9. The whole string matched by the regular expression is
      stored in the special variable $0
    

      
    Example
    
        <!--#if expr="$QUERY_STRING = /^sid=([a-zA-Z0-9]+)/" -->
    
        
          <!--#set var="session" value="$1" -->
    
            
        <!--#endif -->
      
    
      
    

      
    string1 < string2
    
       string1 <= string2
    
       string1 > string2
    
       string1 >= string2
    

      
    Compare string1 with string2. Note, that
      strings are compared literally (using
      strcmp(3)). Therefore the string "100" is less than
      "20".
    

      
    ( test_condition )
    
      
    true if test_condition is true
    

      
    ! test_condition
    
      
    true if test_condition is false
    

      
    test_condition1 &&
        test_condition2
    
      
    true if both test_condition1 and
      test_condition2 are true
    

      
    test_condition1 ||
        test_condition2
    
      
    true if either test_condition1 or
      test_condition2 is true
    
    
    

    
    "=" and "!=" bind more tightly than
    "&&" and "||". "!" binds
    most tightly. Thus, the following are equivalent:
    

    
    
      <!--#if expr="$a = test1 && $b = test2" -->
    
      <!--#if expr="($a = test1) && ($b = test2)" -->
    
    

    
    The boolean operators && and ||
    share the same priority. So if you want to bind such an operator more
    tightly, you should use parentheses.
    

    
    Anything that's not recognized as a variable or an operator
    is treated as a string. Strings can also be quoted:
    'string'. Unquoted strings can't contain whitespace
    (blanks and tabs) because it is used to separate tokens such as
    variables. If multiple strings are found in a row, they are
    concatenated using blanks. So,
    

    
    string1    string2 results in string1 string2
    
      
    
      and
    
      
    
      'string1    string2' results in string1    string2.
    

    
    Optimization of Boolean Expressions
    
      
    If the expressions become more complex and slow down processing
      significantly, you can try to optimize them according to the
      evaluation rules:
    
      
      
      
    • Expressions are evaluated from left to right
      • 
      
    • Binary boolean operators (&& and ||)
          are short circuited wherever possible. In conclusion with the rule
          above that means, mod_include evaluates at first
          the left expression. If the left result is sufficient to determine
          the end result, processing stops here. Otherwise it evaluates the
          right side and computes the end result from both left and right
          results.
      • 
      
    • Short circuit evaluation is turned off as long as there are regular
          expressions to deal with. These must be evaluated to fill in the
          backreference variables ($1 .. $9).
      • 
      
    
      
    If you want to look how a particular expression is handled, you can
      recompile mod_include using the
      -DDEBUG_INCLUDE compiler option. This inserts for every
      parsed expression tokenizer information, the parse tree and how it is
      evaluated into the output sent to the client.
    
    
    

    
    Escaping slashes in regex strings
    
     
    All slashes which are not intended to act as delimiters in your regex must
     be escaped.  This is regardless of their meaning to the regex engine.

    Compatibility:Available in version 2.2.15 and later.
    

    
      
    Under normal circumstances, a file filtered by mod_include
        may contain elements that are either dynamically generated, or that may
        have changed independently of the original file. As a result, by default
        the server is asked not to generate an ETag header for the
        response by adding no-etag to the request notes.
    

      
    The SSIETag directive suppresses this
        behaviour, and allows the server to generate an ETag header.
        This can be used to enable caching of the output. Note that a backend server
        or dynamic content generator may generate an ETag of its own, ignoring
        no-etag, and this ETag will be passed by
        mod_include regardless of the value of this setting.
        SSIETag can take on the following values:
    

      
    

        
    off
    
        
    no-etag will be added to the request notes, and the server
          is asked not to generate an ETag. Where a server ignores the value of
          no-etag and generates an ETag anyway, the ETag will be
          respected.
    

        
    on
    
        
    Existing ETags will be respected, and ETags generated by the server will
          be passed on in the response.

    Under normal circumstances, a file filtered by mod_include
        may contain elements that are either dynamically generated, or that may
        have changed independently of the original file. As a result, by default
        the Last-Modified header is stripped from the response.
    

      
    The SSILastModified directive overrides this
        behaviour, and allows the Last-Modified header to be respected
        if already present, or set if the header is not already present. This can
        be used to enable caching of the output. SSILastModified
        can take on the following values:
    

      
    

        
    off
    
        
    The Last-Modified header will be stripped from responses,
          unless the XBitHack directive
          is set to full as described below.
    

        
    on
    
        
    The Last-Modified header will be respected if already
          present in a response, and added to the response if the response is a
          file and the header is missing. The
          SSILastModified directive
          takes precedence over XBitHack.

    The XBitHack directive controls the parsing
    of ordinary html documents. This directive only affects files associated
    with the MIME-type text/html. XBitHack can take on the following values:
    

    
    
      
    off
    
      
    No special treatment of executable files.
    

      
    on
    
      
    Any text/html file that has the user-execute bit
      set will be treated as a server-parsed html document.
    

      
    full
    
      
    As for on but also test the group-execute bit.
      If it is set, then set the Last-modified date of the
      returned file to be the last modified time of the file. If
      it is not set, then no last-modified date is sent. Setting
      this bit allows clients and proxies to cache the result of
      the request.

      
    Note
    
      
    You would not want to use the full option, unless you assure the
      group-execute bit is unset for every SSI script which might #include a CGI or otherwise produces different output on
      each hit (or could potentially change on subsequent requests).
    

      
    The SSILastModified

    Pending Request Counting Algorithm
    

    

    
    Enabled via lbmethod=bybusyness, this scheduler keeps
    track of how many requests each worker is currently assigned at present. A new
    request is automatically assigned to the worker with the lowest
    number of active requests. This is useful in the case of workers
    that queue incoming requests independently of Apache, to ensure that
    queue length stays even and a request is always given to the worker
    most likely to service it the fastest and reduce latency.
    

    
    In the case of multiple least-busy workers, the statistics (and
    weightings) used by the Request Counting method are used to break the
    tie. Over time, the distribution of work will come to resemble that
    characteristic of byrequests (as implemented
    by mod_lbmethod_byrequests).

    Açıklama
    


    Modülün kullanım amacının kısa bir açıklaması.
    

    top
    

    

    Durum
    

    
    Modülün Apache HTTP sunucusuna ne kadar sıkı bağlı olduğunu belirtir. Başka bir deyişle, modüle ve işlevselliğine erişim kazanmak için sunucuyu yeniden derlemek gerekip gerekmediği ile ilgili durumu belirtir. Bu özniteliğin olası değerleri şunlardır:
    

    
    
      
    MPM
    

      
    “MPM” durumlu bir modül bir Çok Süreçlilik Modülüdür. Diğer modül türlerinin aksine, sunucunun kullandığı MPM modülü sayısı birden fazla olamaz. Bu modül türü temelde sunucuya gelen isteklerin ele alınmasından ve öldürülmesinden sorumludur.
    

      
    Temel
    

      
    “Temel” durumuyla etiketlenmiş bir modül öntanımlı olarak olarak derlenir ve sunucuya öntanımlı olarak yüklenir. Bu bakımdan derleme öncesi paket yapılandırması sırasında modülün derlenmemesi özellikle istenmedikçe bu modül derlenecek ve sunucuya yüklenecektir.
    

      
    Eklenti
    

      
    “Eklenti” durumundaki bir modül normal olarak derlenmez ve sunucuya yüklenmez. Modülü ve işlevselliğini etkin kılmak için sunucunun derleme öncesi paket yapılandırması sırasında modülün derleneceğini açıkça belirttikten sonra gerekirse yeniden derlemeniz gerekir.
    

      
    Deneysel
    

      
    “Deneysel” durumu modülün Apache sunucusunun bir parçası olarak kabul edildiğini ancak modülü denemenin tamamen sizin insiyatifinize bırakıldığı anlamına gelir. Böyle bir modül her şeyiyle belgelenmiştir fakat gerektiği gibi desteklenmemiştir.
    

      
    Harici
    

      
    “Harici” durumu temel Apache dağıtımında bulunmayan (“üçüncü parti”) modüller için kullanılır. Böyle modüller için sorumluluk kabul etmediğimiz gibi bunları desteklemiyoruz.
    
    
    

    top
    

    

    Kaynak Dosyası
    

    
    Karşısına modül kodunu içeren kaynak dosyasının ismi yazılır. Bu isim ayrıca <IfModule> yönergesi tarafından da kullanılır.
    

    top
    

    

    Modül Betimleyici
    

    
    Modüller devingen olarak yüklenirken LoadModule yönergesinde kullanmak için modülü betimleyen dizgedir. Aslında, kaynak dosyasında module türündeki harici değişkenin ismidir.
    

    top
    

    

    Uyumluluk
    

    
    Eğer modül Apache’nin 2. sürüm dağıtımının özgün parçası değilse söz  konusu sürüm burada belirtilir. Ayrıca, modülün kullanımı belli platformlarla sınırlıysa bunun ayrıntıları da burada belirtilir.

    Sommaire
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avec la directive
      ProxyRequests avant
      d'avoir sécurisé votre serveur. Les serveurs
      mandataires ouverts sont dangereux pour votre réseau,
      mais aussi pour l'Internet au sens large.
    
    
    

    
    mod_proxy et ses modules associés implémentent
    un mandataire/passerelle pour le serveur HTTP Apache, et supportent
    de nombreux protocoles courants, ainsi que plusieurs algorithmes de
    répartition de charge. Le support de protocoles et d'algorithmes de
    répartition de charge supplémentaires peut être assuré par des
    modules tiers.
    

    
    Un jeu de modules chargés dans le serveur permet de fournir les
    fonctionnalités souhaitées. Ces modules peuvent être inclus
    statiquement à la compilation, ou dynamiquement via la directive
    LoadModule. Ce jeu de module
    doit comporter :
    

    

    
    En outre, d'autres modules fournissent des fonctionnalités
    étendues. mod_cache et ses modules associés
    fournissent la mise en cache. Les directives SSLProxy*
    du module mod_ssl permettent de contacter des
    serveurs distants en utilisant le protocole SSL/TLS. Ces modules
    additionnels devront être chargés et configurés pour pouvoir
    disposer de ces fonctionnalités.

    Mandataires directs et
    mandataires/passerelles inverses
    
      
    Le serveur HTTP Apache peut être configuré dans les deux modes mandataire
      direct et mandataire inverse (aussi nommé
      mode passerelle).
    

      
    Un mandataire direct standard est un serveur
      intermédiaire qui s'intercale entre le client et le serveur
      demandé. Pour obtenir un contenu hébergé par
      le serveur demandé, le client envoie une requête au
      mandataire en nommant le serveur demandé comme
      cible. Le mandataire extrait alors le contenu depuis le
      serveur demandé et le renvoie enfin au client. Le client doit être
      configuré de manière appropriée pour pouvoir utiliser le mandataire
      direct afin d'accéder à d'autres sites.
    

      
    L'accès à Internet depuis des clients situés derrière un
      pare-feu est une utilisation typique du mandataire direct. Le
      mandataire direct peut aussi utiliser la mise en cache (fournie
      par mod_cache) pour réduire la charge du
      réseau.
    

      
    La fonctionnalité de mandataire direct est activée via la
      directive ProxyRequests.
      Comme les mandataires directs permettent aux clients d'accéder à
      des sites quelconques via votre serveur et de dissimuler leur
      véritable origine, il est indispensable de sécuriser votre serveur de façon à ce que seuls
      les clients autorisés puissent accéder à votre serveur avant
      d'activer la fonctionnalité de mandataire direct.
    

      
    Un mandataire inverse (ou passerelle),
      quant à lui, apparaît au client comme un serveur web standard.
      Aucune configuration particulière du client n'est nécessaire. Le
      client adresse ses demandes de contenus ordinaires dans l'espace
      de nommage du mandataire inverse. Ce dernier décide alors où
      envoyer ces requêtes, et renvoie le contenu au client comme s'il
      l'hébergeait lui-même.
    

      
    L'accès d'utilisateurs depuis Internet vers un serveur situé
      derrière un pare-feu est une utilisation typique du mandataire
      inverse. On peut aussi utiliser les mandataires inverses pour
      mettre en oeuvre une répartition de charge entre plusieurs
      serveurs en arrière-plan, ou fournir un cache pour un serveur
      d'arrière-plan plus lent. Les mandataires inverses peuvent aussi
      tout simplement servir à rassembler plusieurs serveurs dans le
      même espace de nommage d'URLs.
    

      
    La fonctionnalité de mandataire inverse est activée via la
      directive ProxyPass ou
      le drapeau [P] de la directive RewriteRule. Il n'est
      pas nécessaire de définir ProxyRequests pour configurer
      un mandataire inverse.
    
    
    top
    

    

    Exemples simples
    

    
    Les exemples ci-dessous illustrent de manière très basique la
    mise en oeuvre de la fonctionnalité de mandataire et ne sont là que
    pour vous aider à démarrer. Reportez-vous à la documentation de
    chaque directive.
    

    
    Si en outre, vous désirez activer la mise en cache, consultez la
    documentation de mod_cache.
    

    
    Mandataire inverse
    ProxyPass "/foo" "http://foo.example.com/bar"
ProxyPassReverse "/foo" "http://foo.example.com/bar"
    

    

    
    Mandataire direct
    ProxyRequests On
ProxyVia On

<Proxy "*">
  Require host internal.example.com
</Proxy>
    

    
    
    top
    

    

    Accès via un gestionnaire
    

    
    Vous pouvez aussi forcer le traitement d'une requête en tant que
    requête de mandataire inverse en créant un gestionnaire de transfert
    approprié. Dans l'exemple suivant, toutes les requêtes pour
    des scripts PHP seront transmises au serveur FastCGI
    spécifié via un mandat inverse :
    
    

    
    Scripts PHP et mandataire inverse
    <FilesMatch "\.php$">
    # Les sockets Unix nécessitent une version 2.4.7 ou supérieure du
    # serveur HTTP Apache
    SetHandler  "proxy:unix:/path/to/app.sock|fcgi://localhost/"
</FilesMatch>
    

    

      
    Cette fonctionnalité est disponible à partir de la version
      2.4.10 du serveur HTTP Apache.
    

    
    top
    

    

    Workers
    
      
    Le mandataire gère la configuration et les paramètres de
      communication des serveurs originaux au sein d'objets nommés
      workers. Deux types de worker sont fournis : le worker
      par défaut du mandataire direct et le worker par défaut du
      mandataire inverse. Il est aussi possible de définir explicitement
      des workers supplémentaires.
    

      
    Les deux workers par défaut possèdent une configuration figée
      et seront utilisés si aucun autre worker ne correspond à la
      requête. Ils ne réutilisent pas les connexions et n'utilisent pas les
      connexions HTTP persistantes (Keep-Alive). En effet, les
      connexions TCP vers le serveur original sont fermées et ouvertes
      pour chaque requête.
    

      
    Les workers définis explicitement sont identifiés par leur URL.
      Ils sont en général définis via les directives ProxyPass ou ProxyPassMatch lorsqu'on les
      utilise dans le cadre d'un mandataire inverse :
    

      
    ProxyPass "/example" "http://backend.example.com" connectiontimeout=5 timeout=30
    

    
      

      
    Cette directive va créer un worker associé à l'URL du serveur
      original http://backend.example.com qui utilisera les
      valeurs de timeout données. Lorsqu'ils sont utilisés dans le cadre
      d'un mandataire direct, les workers sont en général définis via la
      directive ProxySet,
    

      
    ProxySet "http://backend.example.com" connectiontimeout=5 timeout=30
    

    
      

      
    ou encore via les directives Proxy et ProxySet :
    

      
    <Proxy "http://backend.example.com">
  ProxySet connectiontimeout=5 timeout=30
</Proxy>
    


      
    L'utilisation de workers définis explicitement dans le mode
      mandataire direct n'est pas très courante, car les mandataires
      directs communiquent en général avec de nombreux serveurs
      originaux. La création explicite de workers pour certains serveurs
      originaux peut cependant s'avérer utile si ces serveurs sont
      très souvent sollicités. A leur niveau, les workers explicitement
      définis ne possèdent aucune notion de mandataire direct ou
      inverse. Ils encapsulent un concept de communication commun avec
      les serveurs originaux. Un worker créé via la directive ProxyPass pour être utilisé dans le
      cadre d'un mandataire inverse sera aussi utilisé dans le cadre
      d'un mandataire directe chaque fois que l'URL vers le serveur
      original correspondra à l'URL du worker, et vice versa.
    

      
    L'URL qui identifie un worker correspond à l'URL de son serveur
      original, y compris un éventuel chemin donné :
    

      
    ProxyPass "/examples" "http://backend.example.com/examples"
ProxyPass "/docs" "http://backend.example.com/docs"
    


      
    Dans cet exemple, deux workers différents sont définis, chacun
      d'eux utilisant des configurations et jeux de connexions
      séparés.
    

      
    Partage de workers
    
        
    Le partage de workers intervient lorsque les URLs des workers
	s'entrecoupent, ce qui arrive lorsque l'URL d'un worker
	correspond au début de l'URL d'un autre worker défini plus loin
	dans le fichier de configuration. Dans l'exemple suivant,
    

        
    ProxyPass "/apps" "http://backend.example.com/" timeout=60
ProxyPass "/examples" "http://backend.example.com/examples" timeout=10
    


        
    le second worker n'est pas vraiment créé. C'est le premier
	worker qui est en fait utilisé. L'avantage de ceci réside dans
	le fait qu'il n'existe qu'un seul jeu de connexions, ces
	dernières étant donc réutilisées plus souvent. Notez que tous
	les attributs de configuration définis explicitement pour le
	deuxième worker seront ignorés, ce qui sera journalisé en tant
	qu'avertissement. Ainsi, dans l'exemple ci-dessus, la valeur de
	timeout retenue pour l'URL /exemples sera
	60, et non 10 !
    

        
    Si vous voulez empêcher le partage de workers, classez vos
	définitions de workers selon la longueur des URLs, de la plus
	longue à la plus courte. Si au contraire vous voulez favoriser
	ce partage, utilisez l'ordre de classement inverse. Voir aussi
	l'avertissement à propos de l'ordre de classement des directives
	ProxyPass.
    

      
     

      
    Les workers définis explicitement sont de deux sortes :
      workers directs et workers de répartition (de
      charge). Ils supportent de nombreux attributs de
      configuration importants décrits dans la directive ProxyPass. Ces mêmes attributs
      peuvent aussi être définis via la directive ProxySet.
    

      
    Le jeu d'options disponibles pour un worker direct dépend du
      protocole spécifié dans l'URL du serveur original. Les protocoles
      disponibles comprennent ajp, fcgi,
      ftp, http et scgi.
    

      
    Les workers de répartition sont des workers virtuels qui
      utilisent les workers directs, connus comme faisant partie de leurs
      membres, pour le traitement effectif des requêtes. Chaque
      répartiteur peut comporter plusieurs membres. Lorsqu'il traite une
      requête, il choisit un de ses membres en fonction de l'algorithme
      de répartition de charge défini.
    

      
    Un worker de répartition est créé si son URL de worker comporte
      balancer comme indicateur de protocole. L'URL du
      répartiteur permet d'identifier de manière unique le worker de
      répartition. La directive BalancerMember permet d'ajouter des
      membres au répartiteur.
    

      
    Résolution DNS pour les domaines originaux
    
      
    La résolution DNS s'effectue lorsque le socket vers le
      domaine original est créé pour la première fois. Lorsque la réutilisation
      des connexions est activée, chaque domaine d'arrière-plan n'est résolu qu'une
      seule fois pour chaque processus enfant, et cette résolution est mise en
      cache pour toutes les connexions ultérieures jusqu'à ce que le processus enfant
      soit recyclé. Ce comportement doit être pris en considération lorsqu'on
      planifie des tâches de maintenance du DNS impactant les domaines
      d'arrière-plan. Veuillez aussi vous reporter aux paramètres de la
      directive ProxyPass pour plus de
      détails à propos de la réutilisation des connexions.
    
      
    

    
    top
    

    

    Contrôler l'accès à votre
    mandataire
    
      
    Vous pouvez restreindre l'accès à votre mandataire via le bloc
      de contrôle <Proxy> comme dans
      l'exemple suivant :
    

      
    <Proxy "*">
  Require ip 192.168.0
</Proxy>
    


      
    Pour plus de détails sur les directives de contrôle d'accès,
      voir la documentation du module
      mod_authz_host.
    

      
    Restreindre l'accès de manière stricte est essentiel si vous
      mettez en oeuvre un mandataire direct (en définissant la directive
      ProxyRequests à "on").
      Dans le cas contraire, votre serveur pourrait être utilisé par
      n'importe quel client pour accéder à des serveurs quelconques,
      tout en masquant sa véritable identité. Ceci représente un danger
      non seulement pour votre réseau, mais aussi pour l'Internet au
      sens large. Dans le cas de la mise en oeuvre d'un mandataire
      inverse (en utilisant la directive ProxyPass avec ProxyRequests Off), le contrôle
      d'accès est moins critique car les clients ne peuvent contacter
      que les serveurs que vous avez spécifiés.
    

      
    Voir aussi la variable d'environnement Proxy-Chain-Auth.
    

    
    top
    

    

    Ralentissement au démarrage
    
      
    Si vous utilisez la directive ProxyBlock, les noms d'hôtes sont résolus en adresses
      IP puis ces dernières mises en cache au cours du démarrage
      à des fins de tests de comparaisons ultérieurs. Ce processus peut
      durer plusieurs secondes (ou d'avantage) en fonction de la vitesse
      à laquelle s'effectue la résolution des noms d'hôtes.
    
    
    top
    

    

    Mandataire en Intranet
    
      
    Un serveur mandataire Apache httpd situé à l'intérieur d'un Intranet
      doit faire suivre les requêtes destinées à un serveur externe à
      travers le pare-feu de l'entreprise (pour ce faire, définissez la
      directive ProxyRemote de
      façon à ce qu'elle fasse suivre le protocole concerné
      vers le mandataire du pare-feu). Cependant, lorsqu'il doit accéder
      à des ressources situées dans l'Intranet, il peut se passer du
      pare-feu pour accéder aux serveurs. A cet effet, la directive
      NoProxy permet de
      spécifier quels hôtes appartiennent à l'Intranet et peuvent donc
      être accédés directement.
    

      
    Les utilisateurs d'un Intranet ont tendance à oublier le nom du
      domaine local dans leurs requêtes WWW, et demandent par exemple
      "http://un-serveur/" au lieu de
      http://un-serveur.example.com/. Certains serveurs
      mandataires commerciaux acceptent ce genre de requête et les
      traitent simplement en utilisant un nom de domaine local
      implicite. Lorsque la directive ProxyDomain est utilisée et si le
      serveur est configuré comme
      mandataire, Apache httpd peut renvoyer une réponse de redirection et
      ainsi fournir au client l'adresse de serveur correcte,
      entièrement qualifiée. C'est la méthode à privilégier car le
      fichier des marque-pages de l'utilisateur contiendra alors des
      noms de serveurs entièrement qualifiés.
    
    
    top
    

    

    Ajustements relatifs au
    protocole
    
      
    Pour les cas où mod_proxy envoie des requêtes
      vers un serveur qui n'implémente pas correctement les connexions
      persistantes ou le protocole HTTP/1.1, il existe deux variables
      d'environnement qui permettent de forcer les requêtes à utiliser
      le protocole HTTP/1.0 avec connexions non persistantes. Elles
      peuvent être définies via la directive SetEnv.
    

      
    Il s'agit des variables force-proxy-request-1.0 et
      proxy-nokeepalive.
    

      
    <Location "/buggyappserver/">
  ProxyPass "http://buggyappserver:7001/foo/"
  SetEnv force-proxy-request-1.0 1
  SetEnv proxy-nokeepalive 1
</Location>
    


      
    A partir de la version 2.4.26 du serveur HTTP Apache, la définition de
      la variable d'environnement "no-proxy" permet de désactiver
      mod_proxy dans le traitement de la requête courante.
      Cette variable doit être définie via la directive SetEnvIf car la directive SetEnv n'est pas évaluée assez tôt.

    Corps de requêtes
    

    
    Certaines méthodes de requêtes comme POST comportent un corps de
    requête. Le protocole HTTP stipule que les requêtes qui comportent
    un corps doivent soit utiliser un codage de transmission
    fractionnée (chunked transfer encoding), soit envoyer un en-tête de requête
    Content-Length. Lorsqu'il fait suivre ce genre de
    requête vers le serveur demandé, mod_proxy_http
    s'efforce toujours d'envoyer l'en-tête Content-Length.
    Par contre, si la taille du corps est importante, et si la requête
    originale utilise un codage à fractionnement, ce dernier peut aussi
    être utilisé dans la requête montante. Ce comportement peut être
    contrôlé à l'aide de variables
    d'environnement. Ainsi, si elle est définie, la variable
    proxy-sendcl assure une compatibilité maximale avec les
    serveurs demandés en imposant l'envoi de l'en-tête
    Content-Length, alors que
    proxy-sendchunked diminue la consommation de ressources
    en imposant l'utilisation d'un codage à fractionnement.
    

    
    Dans certaines circonstances, le serveur doit mettre en file
    d'attente sur disque les corps de requêtes afin de satisfaire le
    traitement demandé des corps de requêtes. Par exemple, cette mise en
    file d'attente se produira si le corps original a été envoyé selon un
    codage morcelé (et possède une taille importante), alors que
    l'administrateur a demandé que les requêtes du serveur
    d'arrière-plan soient envoyées avec l'en-tête Content-Length ou en
    HTTP/1.0. Cette mise en file d'attente se produira aussi si le corps
    de la requête contient déjà un en-tête Content-Length, alors que le
    serveur est configuré pour filtrer les corps des requêtes entrantes.
    

    
    La directive LimitRequestBody ne s'applique qu'aux
    corps de requêtes que le serveur met en file d'attente sur disque.
    

    
    top
    

    

    En-têtes de requête du mandataire
    inverse
    

    
    Lorsqu'il est configuré en mode mandataire inverse (en utilisant
    par exemple la directive ProxyPass),
    mod_proxy_http ajoute plusieurs en-têtes de requête
    afin de transmettre des informations au serveur demandé. Ces
    en-têtes sont les suivants :
    

    
    
      
    X-Forwarded-For
    
      
    L'adresse IP du client.
    
      
    X-Forwarded-Host
    
      
    L'hôte d'origine demandé par le client dans l'en-tête de
      requête HTTP Host.
    
      
    X-Forwarded-Server
    
      
    Le nom d'hôte du serveur mandataire.
    
    
    

    
    Ces en-têtes doivent être utilisés avec précautions sur le
    serveur demandé, car ils contiendront plus d'une valeur (séparées
    par des virgules) si la requête originale contenait déjà un de ces
    en-têtes. Par exemple, vous pouvez utiliser
    %{X-Forwarded-For}i dans la chaîne de format du journal
    du serveur demandé pour enregistrer les adresses IP des clients
    originaux, mais il est possible que vous obteniez plusieurs adresses
    si la requête passe à travers plusieurs mandataires.
    

    
    Voir aussi les directives ProxyPreserveHost et ProxyVia directives, qui permettent
    de contrôler d'autres en-têtes de requête.
    

    
    Note : Si vous devez ajouter des en-têtes particuliers à la
    requête mandatée, utilisez la directive  RequestHeader.

    Cette directive permet d'ajouter un membre à un groupe de
    répartition de charge. Elle peut se trouver dans un conteneur
    <Proxy balancer://...>, et accepte
    tous les paramètres de paires clé/valeur que supporte la directive
    ProxyPass.
    
    
    La directive BalancerMember accepte un paramètre
    supplémentaire : loadfactor. Il s'agit du facteur de
    charge du membre - un nombre décimal entre 1.0 (valeur par défaut) et 100.0, qui
    définit la charge à appliquer au membre en question.
    
    
    L'argument balancerurl n'est requis que s'il ne se trouve pas
    dèjà dans la directive de conteneur <Proxy
    balancer://...>. Il correspond à l'URL d'un
    répartiteur de charge défini par une directive ProxyPass.
    
    
    La partie chemin de l'URL du répartiteur dans toute directive de
    conteneur <Proxy balancer://...> est

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    Cette directive n'a d'utilité que pour les serveurs mandataires
    Apache httpd au sein d'Intranets. La directive
    NoProxy permet de spécifier une liste de
    sous-réseaux, d'adresses IP, de serveurs et/ou de domaines séparés
    par des espaces. Une requête pour un serveur qui correspond à un ou
    plusieurs critères sera toujours servie par ce serveur directement,
    sans être redirigée vers le(s) serveur(s) mandataire(s) défini(s) par
    la directive ProxyRemote.
    

    
    Exemple
    ProxyRemote  "*"  "http://firewall.example.com:81"
NoProxy         ".example.com" "192.168.112.0/21"
    

    

    
    Le type des arguments serveur de la directive
    NoProxy appartiennent à la liste suivante
    :
    

    
    
    
    
    Domaine
    
    
    
    
    Un domaine est ici un nom de domaine DNS partiellement
    qualifié précédé d'un point. Il représente une liste de serveurs qui
    appartiennent logiquement au même domaine ou à la même zonz DNS
    (en d'autres termes, les nom des serveurs se terminent tous par
    domaine).
    

    
    Exemple
    
      .com .example.org.
    
    

    
    Pour faire la distinction entre domaines et nom d'hôtes (des points de vue à la fois
    syntaxique et
    sémantique, un domaine DNS pouvant aussi avoir un enregistrement DNS
    de type A !), les domaines sont toujours spécifiés en les
    préfixant par un point.
    

    
    Note
    
      
    Les comparaisons de noms de domaines s'effectuent sans tenir
      compte de la casse, et les parties droites des Domaines
      sont toujours censées correspondre à la racine de l'arborescence
      DNS, si bien que les domaines .ExEmple.com et
      .exemple.com. (notez le point à la fin du nom) sont
      considérés comme identiques. Comme une comparaison de domaines ne
      nécessite pas de recherche DNS, elle est beaucoup plus efficace
      qu'une comparaison de sous-réseaux.
    
    
    

    
    
    Sous-réseau
    
    
    
    
    Un Sous-réseau est une adresse internet partiellement
    qualifiée sous forme numérique (quatre nombres séparés par des
    points), optionnellement suivie d'un slash et du masque de
    sous-réseau spécifiant le nombre de bits significatifs dans le
    Sous-réseau. Il représente un sous-réseau de serveurs qui
    peuvent être atteints depuis la même interface réseau. En l'absence
    de masque de sous-réseau explicite, il est sous-entendu que les
    digits manquants (ou caractères 0) de fin spécifient le masque de
    sous-réseau (Dans ce cas, le masque de sous-réseau ne peut être
    qu'un multiple de 8). Voici quelques exemples :
    

    
    
    
    192.168 ou 192.168.0.0
    
    
    le sous-réseau 192.168.0.0 avec un masque de sous-réseau
    implicite de 16 bits significatifs (parfois exprimé sous la forme
    255.255.0.0)
    
    
    192.168.112.0/21
    
    
    le sous-réseau 192.168.112.0/21 avec un masque de
    sous-réseau implicite de 21 bits significatifs (parfois exprimé
    sous la forme255.255.248.0)
    
    
    

    
    Comme cas extrêmes, un Sous-réseau avec un masque de
    sous-réseau de 32 bits significatifs est équivalent à une adresse IP, alors qu'un Sous-réseau avec un masque de
    sous-réseau de 0 bit significatif (c'est à dire 0.0.0.0/0) est
    identique à la constante _Default_, et peut correspondre
    à toute adresse IP.
    

    
    
    Adresse IP
    
    
    
    
    Une Adresse IP est une adresse internet pleinement
    qualifiée sous forme numérique (quatre nombres séparés par des
    points). En général, cette adresse représente un serveur, mais elle
    ne doit pas nécessairement correspondre à un nom de domaine DNS.
    
    
    Exemple
    
      192.168.123.7
    
    

    
    Note
    
      
    Une Adresse IP ne nécessite pas de résolution DNS,
      et peut ainsi s'avérer plus efficace quant aux performances
      d'Apache.
    
    
    

    
    
    Nom de serveur
    
    
    
    
    Un Nom de serveur est un nom de domaine DNS pleinement
    qualifié qui peut être résolu en une ou plusieurs adresses IP par le
    service de noms de domaines DNS. Il représente un hôte logique (par
    opposition aux Domaines, voir
    ci-dessus), et doit pouvoir être résolu en une ou plusieurs adresses IP (ou souvent en une liste
    d'hôtes avec différentes adresses
    IP).
    

    
    Exemples
    
      prep.ai.example.edu
    
      www.example.org
    
    

    
    Note
    
      
    Dans de nombreuses situations, il est plus efficace de
      spécifier une adresse IP qu'un
      Nom de serveur car cela évite d'avoir à effectuer une
      recherche DNS. La résolution de nom dans Apache httpd peut prendre un
      temps très long lorsque la connexion avec le serveur de noms
      utilise une liaison PPP lente.
    
      
    Les comparaisons de Nom de serveur s'effectuent sans tenir
      compte de la casse, et les parties droites des Noms de serveur
      sont toujours censées correspondre à la racine de l'arborescence
      DNS, si bien que les domaines WWW.ExEmple.com et
      www.example.com. (notez le point à la fin du nom) sont
      considérés comme identiques.

    Description:Conteneur de directives s'appliquant à des ressources
mandatées
    

    Syntaxe:<Proxy url-avec-jokers> ...</Proxy>
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    Les directives situées dans une section <Proxy> ne s'appliquent qu'au contenu
    mandaté concerné. Les jokers de style shell sont autorisés.
    

    
    Par exemple, les lignes suivantes n'autoriseront à accéder à un
    contenu via votre serveur mandataire que les hôtes appartenant à
    votre-reseau.example.com :
    

    
    <Proxy "*">
  Require host votre-reseau.example.com
</Proxy>
    


    
    Dans l'exemple suivant, tous les fichiers du répertoire
    foo de example.com seront traités par le
    filtre INCLUDES lorsqu'ils seront envoyés par
    l'intermédiaire du serveur mandataire :
    

    
    <Proxy "http://example.com/foo/*">
  SetOutputFilter INCLUDES
</Proxy>
    


    
    Différences avec la section de configuration Location
    
      
    Une URL d'arrière-plan sera concernée par le conteneur Proxy si
      elle commence par la url-avec-jokers, même si le
      dernier segment de chemin de la directive ne correspond qu'à un
      préfixe de segment dee chemin de l'URL d'arrière-plan. Par exemple, <Proxy
      "http://example.com/foo"> correspondra entre autres aux URLs
      http://example.com/foo, http://example.com/foo/bar, et
      http://example.com/foobar. La correspondance de l'URL finale
      diffère du comportement de la section <Location> qui, pour le cas de cette note,
      traitera le segment de chemin final comme s'il se terminait par un
      slash.
    
      
    Pour un contrôle plus fin de la correspondance des URL, voir la
      directive <ProxyMatch>.

    adresses IP des éléments de la liste qui peuvent correspondre à des
    noms d'hôtes au cours du démarrage, et les mettra en cache à des

2.5.1. du serveur HTTP Apache.
    

    
    
    Cette directive est utile pour les configurations de mandataires
    inverses, lorsque vous souhaitez que les pages d'erreur envoyées
    aux utilisateurs finaux présentent un aspect homogène. Elle permet
    aussi l'inclusion de fichiers (via les SSI de
    mod_include) pour obtenir le code d'erreur et agir
    en conséquence (le comportement par défaut afficherait la page
    d'erreur du serveur mandaté, alors que c'est le message d'erreur SSI
    qui sera affiché si cette directive est à "on").
    

    
    Cette directive n'affecte pas le traitement des réponses
    informatives (1xx), de type succès normal (2xx), ou de redirection
    (3xx).
    

    
    Par défaut, ProxyErrorOverride affecte toutes les
    réponses avec un code compris entre 400 inclus et 600 exclus.
    

    
    Exemple de configuration par défaut
    ProxyErrorOverride  On
    

    

    
    Pour n'affecter que les réponses possèdant certains codes d'état
    particuliers, vous pouvez spécifier ces derniers sous la forme d'une liste
    en les séparant par des espaces. Les réponses dont le code d'état ne fait
    pas partie de la liste ne seront pas affectées. Vous ne pouvez spécifier que
    des codes d'erreurs, donc compris entre 400 inclus et 600 exclus.
    

    
    Exemple de configuration personnalisée
    ProxyErrorOverride  On 403 405 500 501 502 503 504

    Directive ProxyIOBufferSize
    

    

    Description:Détermine la taille du tampon interne de transfert de
données
    

    Syntaxe:ProxyIOBufferSize octets
    

    Défaut:ProxyIOBufferSize 8192
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    La directive ProxyIOBufferSize permet
    d'ajuster la taille du tampon interne utilisé comme bloc-note pour
    les transferts de données entre entrée et sortie. La taille minimale
    est de 512 octets.
    

    
    Dans la plupart des cas, il n'y a aucune raison de modifier cette
    valeur.
    

    
    Si elle est utilisée avec AJP, cette directive permet de définir
    la taille maximale du paquet AJP en octets. Si la valeur spécifiée
    est supérieure à 65536, elle est corrigée et prend la valeur 65536.
    Si vous ne conservez pas
    la valeur par défaut, vous devez aussi modifier l'attribut
    packetSize de votre connecteur AJP du côté de Tomcat !
    L'attribut packetSize n'est disponible que dans Tomcat
    5.5.20+ et 6.0.2+.
    
    
    Il n'est normalement pas nécessaire de modifier la taille
    maximale du paquet. Des problèmes ont cependant été rapportés avec
    la valeur par défaut lors de l'envoi de certificats ou de chaînes de
    certificats.

    Directive <ProxyMatch>
    

    

    Description:Conteneur de directives s'appliquant à des ressources
mandatées correspondant à une expression rationnelle
    

    Syntaxe:<ProxyMatch regex> ...</ProxyMatch>
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    La directive <ProxyMatch> est
    identique à la directive <Proxy>, à l'exception qu'elle définit
    les URLs auxquelles elle s'applique en utilisant une expression rationnelle.
    

    
    A partir de la version 2.4.8, les groupes nommés et les
    références arrières sont extraits et enregistrés dans
    l'environnement avec leur nom en majuscules et préfixé par "MATCH_". Ceci permet
    de référencer des URLs dans des expressions
    ou au sein de modules comme mod_rewrite. Pour
    éviter toute confusion, les références arrières numérotées (non
    nommées) sont ignorées. Vous devez utiliser à la place des groupes
    nommés.
    


    <ProxyMatch "^http://(?<sitename>[^/]+)">
    Require ldap-group cn=%{env:MATCH_SITENAME},ou=combined,o=Example
</ProxyMatch>

    Directive ProxyMaxForwards
    

    

    Description:Nombre maximum de mandataires à travers lesquelles une
requête peut être redirigée
    

    Syntaxe:ProxyMaxForwards nombre
    

    Défaut:ProxyMaxForwards -1
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    Compatibilité:Comportement par défaut
modifié dans 2.2.7
    

    
    
    La directive ProxyMaxForwards permet de
    spécifier le nombre maximum de mandataires à travers lesquels une
    requête peut passer dans le cas où la la requête ne contient pas
    d'en-tête Max-Forwards. Ceci permet de se prémunir
    contre les boucles infinies de mandataires ou contre les attaques de
    type déni de service.
    

    
    Exemple
    ProxyMaxForwards 15
    

    

    
    Notez que la définition de la directive
    ProxyMaxForwards constitue une violation du
    protocole HTTP/1.1 (RFC2616), qui interdit à un mandataire de
    définir Max-Forwards si le client ne l'a pas fait
    lui-même. Les versions précédentes d'Apache httpd la définissaient
    systématiquement. Une valeur négative de
    ProxyMaxForwards, y compris la valeur par
    défaut -1, implique un comportement compatible avec le protocole,
    mais vous expose aux bouclages infinis.

    Directive ProxyPass
    

    

    Description:Référencer des serveurs distants depuis
l'espace d'URLs du serveur local
    

    Syntaxe:ProxyPass [chemin] !|url [clé=valeur
  [clé=valeur ...]] [nocanon] [interpolate] [noquery]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy
    

    Compatibilité:Les sockets de style Unix (Unix Domain Socket - UDS)
sont supportés à partir de la version 2.4.7 du serveur HTTP Apache
    

    
    
    Cette directive permet de référencer des serveurs distants depuis
    l'espace d'URLs du serveur local. Le serveur
    local n'agit pas en tant que mandataire au sens conventionnel, mais
    plutôt comme miroir du serveur distant. Le serveur local est
    souvent nommé mandataire inverse ou
    passerelle. L'argument chemin est le nom d'un
    chemin virtuel local ; url est une URL partielle pour le
    serveur distant et ne doit pas contenir de chaîne d'arguments.
    

    
    Il est fortement recommandé de revoir le concept de Worker avant d'aller plus loin.
    

    
    Cette directive n'est pas supportée au sein des sections <Directory>, <If> et <Files>.
    

    
    En général, la directive ProxyRequests doit être définie à
    off lorsqu'on utilise la directive
    ProxyPass.
    

    
    Les sockets de style Unix sont supportés à partir de la version
    2.4.7 du serveur HTTP Apache ; pour utiliser cette fonctionnalité,
    il suffit d'utiliser une URL cible préfixée par
    unix:/path/lis.sock|. Par exemple, pour mandater HTTP
    et cibler l'UDS /home/www.socket, vous devez utiliser
    unix:/home/www.socket|http://localhost/whatever/.
    

    
    Note :Le chemin associé à l'URL
    unix: tient compte de la directive
    DefaultRuntimeDir.
    

    
    Lorsque cette directive est utilisée dans une section <Location>, le premier
    argument est omis et le répertoire local est obtenu à partir de
    l'argument de la directive <Location>. Il en est de même à l'intérieur
    d'une section <LocationMatch>, mais le résultat ne sera
    probablement pas celui attendu car ProxyPassReverse va interpréter
    l'expression rationnelle littéralement comme un chemin ; si besoin
    est dans ce cas, définissez la directive ProxyPassReverse en dehors
    de la section, ou dans une section <Location> séparée.
    

    
    Supposons que le serveur local a pour adresse
    http://example.com/ ; alors la ligne
    

    
    <Location "/mirror/foo/">
    ProxyPass "http://backend.example.com/"
</Location>
    


    
    va convertir en interne toute requête pour
    http://example.com/mirror/foo/bar en une requête
    mandatée pour http://backend.example.com/bar.
    

    
    Si vous avez besoin d'un configuration de mandataire inverse plus
    souple, reportez-vous à la documentaion de la directive RewriteRule et son drapeau
    [P].
    

    
    La syntaxe alternative suivante est valide, bien qu'elle puisse
    induire une dégradation des performances lorsqu'elle est
    présente en très grand nombre. Elle possède l'avantage de
    permettre un contrôle dynamique via l'interface Balancer Manager :
    

    
    ProxyPass "/mirror/foo/" "http://backend.example.com/"
    


    
    
    
    Si le premier argument se termine par un slash
    /, il doit en être de même pour le second argument
    et vice versa. Dans le cas contraire, il risque de manquer des
    slashes nécessaires dans la requête résultante vers le serveur
    d'arrière-plan et les résulats ne seront pas ceux attendus.
    
    
    
    

    
    Le drapeau ! permet de soustraire un sous-répertoire
    du mandat inverse, comme dans l'exemple suivant :
    

    
    <Location "/mirror/foo/">
    ProxyPass "http://backend.example.com/"
</Location>
<Location "/mirror/foo/i">
    ProxyPass "!"
</Location>
    


    
    ProxyPass "/mirror/foo/i" "!"
ProxyPass "/mirror/foo" "http://backend.example.com"
    


    
    va mandater toutes les requêtes pour /mirror/foo
    vers backend.example.com, sauf les requêtes
    pour /mirror/foo/i.
    

    
    Mélanger plusieurs configurations ProxyPass dans différents contextes ne
    fonctionne pas :
    
    
    ProxyPass "/mirror/foo/i" "!"
<Location "/mirror/foo/">
    ProxyPass "http://backend.example.com/"
</Location>
    

    
    Dans ce cas, une requête pour /mirror/foo/i sera tout de
    même mandatée car c'est la directive ProxyPass de la
    section Location qui sera évaluée en premier. Le fait que la directive
    ProxyPass supporte les deux contextes serveur
    principal et répertoire ne signifie pas que sa portée et sa position dans le
    fichier de configuration va garantir une quelconque priorité et/ou
    chronologie de prise en compte.
    

    
    Ordre de classement des directives ProxyPass
    
      
    Les directives ProxyPass et ProxyPassMatch sont évaluées dans
      l'ordre de leur apparition dans le fichier de configuration. La
      première règle qui correspond s'applique. Vous devez donc en
      général classer les règles ProxyPass qui entrent en conflit de
      l'URL la plus longue à la plus courte. Dans le cas contraire, les
      règles situées après une règle dont l'URL correspond au début de
      leur propre URL seront ignorées. Notez que tout ceci est en
      relation avec le partage de workers.
    
      
      
    
    
    Chronologie de prise en compte des directives
    ProxyPass au sein des sections Locations
    
      
    On ne peut placer
      qu'une seule directive ProxyPass dans une section
      Location, et c'est la section
      la plus spécifique qui l'emportera.
    
     
    
     
    Exclusions et variable d'environnement no-proxy
    
      
    Les exclusions doivent se situer avant
      les directives ProxyPass générales. A partir de la
      version 2.4.26 du serveur HTTP Apache, la variable
      d'environnement "no-proxy" est une alternative aux exclusions et constitue
      le seul moyen de configurer une exclusion pour une directive
      ProxyPass dans le contexte d'une section Location. Cette variable doit être définie via
      la directive SetEnvIf car la
      directive SetEnv n'est pas évaluée
      assez tôt.
    

    
     

    
    ProxyPass clé=valeur Paramètres
    

    
    Depuis la version 2.1 du serveur HTTP Apache, mod_proxy supporte
    les groupements de connexions vers un serveur d'arrière-plan. Les
    connexions créées à la demande peuvent être enregistrées dans un
    groupement pour une utilisation ultérieure. La taille du groupe
    ainsi que d'autres caractéristiques peuvent être définies via la
    directive ProxyPass au moyen de paramètres
    clé=valeur dont la description fait l'objet des
    tableaux ci-dessous.
    

    
    Nombre maximum de connexions vers
    l'arrière-plan
    
     
    Par défaut, mod_proxy permet et met en réserve le
    nombre maximum de connexions pouvant être utilisées simultanément par le
    processus enfant concerné du serveur web. Le paramètre max
    permet de réduire cette valeur par défaut. Le jeu de connexions est maintenu
    au niveau de chaque processus enfant du serveur web, max et les
    autres réglages n'étant pas coordonnés entre ces différents processus, sauf
    bien entendu lorsqu'un seul processus enfant n'est autorisé par la
    configuration ou le MPM utilisé.
     
    
    
    
    Le paramètre ttl,
    quant à lui, permet de définir une durée de vie optionnelle ; les
    connexions qui n'ont pas été utilisées pendant au moins
    ttl secondes seront fermées. ttl permet
    aussi d'empêcher l'utilisation d'une connexion susceptible d'être
    fermée suite à une fin de vie de connexion persistante sur le
    serveur d'arrière-plan.
    

    
    Exemple
    ProxyPass "/example" "http://backend.example.com" max=20 ttl=120 retry=300
    

    

    
    Paramètres de worker (directive BalancerMember)
    
    
    
    
    Paramètre
        Défaut
        Description
    
    
    min
        0
        Nombre minimum d'entrées dans le pool de connexions,
	distinct du nombre de connexions effectif. La valeur par défaut
	ne doit être modifiée que dans des circonstances particulières
	où la mémoire associée aux connexions avec le serveur
	d'arrière-plan doit être préallouée ou réservée dans le tas.
    
    
    max
        1...n
        Nombre maximum de connexions autorisées vers le serveur
	d'arrière-plan. La valeur par défaut correspond au nombre de
	threads par processus pour le MPM (Module Multi Processus)
	actif. La valeur sera toujours 1 pour le MPM Prefork, alors
	qu'elle dépendra de la définition de la directive
	ThreadsPerChild pour les autres MPMs.
    
    
    smax
        max
        Les entrées du pool de connexions conservées au delà de
	cette limite sont libérées au cours de certaines opérations si
	elles n'ont pas été utilisées au cours de leur durée de vie,
	définie par le paramètre ttl. Si l'entrée du pool
	de connexions est associée à une connexion, cette dernière sera
	fermée. La valeur par défaut ne doit être modifiée que dans des
	circonstances particulières où les entrées du pool de connexions
	et toutes connexions associées qui ont dépassé leur durée de vie
	doivent être libérées ou fermées de manière plus autoritaire.
    
    
    acquire
        -
        Cette clé permet de définir le délai maximum d'attente pour
	une connexion libre dans le jeu de connexions, en millisecondes.
	S'il n'y a pas de connexion libre dans le jeu, Apache httpd renverra
	l'état SERVER_BUSY au client.
    
    
    
    connectiontimeout
        timeout
        Délai d'attente d'une connexion en secondes.
        La durée en secondes pendant laquelle Apache httpd va attendre pour
	l'établissement d'une connexion vers le serveur d'arrière-plan.
	Le délai peut être spécifié en millisecondes en ajoutant le
	suffixe ms.
    
    
    
    disablereuse
        Off
        Vous pouvez utiliser cette clé pour forcer mod_proxy à
	fermer immédiatement une connexion vers le serveur
	d'arrière-plan après utilisation, et ainsi désactiver le jeu de
	connexions permanentes vers ce serveur. Ceci peut s'avérer utile
	dans des situations où un pare-feu situé entre Apache httpd et le
	serveur d'arrière-plan (quelque soit le protocole) interrompt
	des connexions de manière silencieuse, ou lorsque le serveur
	d'arrière-plan lui-même est accessible par rotation de DNS
	(round-robin DNS). Lorsque la réutilisation des connexions est activée,
	chaque domaine d'arrière-plan n'est résolu (via une requête DNS) qu'une
	seule fois par chaque processus enfant et mis en cache pour toutes les
	connexions ultérieures jusqu'au recyclage du processus concerné.	
	Pour désactiver la réutilisation du jeu de
	connexions, définissez cette clé à On.
    
    
    
    enablereuse
        On
        Ce paramètre est utilisé par les gestionnaires de protocole pour
	lesquels la réutilisation des connexions est optionnelle (comme
	mod_proxy_fcgi). C'est le contraire du
	paramètre 'disablereuse' ci-dessus, et il est supporté par les
	versions 2.4.11 et supérieures du serveur HTTP Apache.
    
    
    
    flushpackets
        off
        Permet de définir si le module mandataire doit vider
	automatiquement le tampon de sortie après chaque tronçon de
	données. 'off' signifie que le tampon sera vidé si
	nécessaire ;
	'on' signifie que le tampon sera vidé après chaque envoi d'un
	tronçon de données, et 'auto' que le tampon sera vidé après un
	délai de 'flushwait' millisecondes si aucune entrée n'est reçue.
	Actuellement, cette clé n'est supportée que par mod_proxy_ajp et
	mod_proxy_fcgi.
    
    
    
    flushwait
        10
        Le délai d'attente pour une entrée additionnelle, en
	millisecondes, avant le vidage du tampon en sortie dans le cas
	où 'flushpackets' est à 'auto'.
    
    
    
    iobuffersize
        8192
        Permet de définir la taille du tampon d'entrées/sorties du
	bloc-notes interne. Cette clé vous permet d'outrepasser la
	directive ProxyIOBufferSize pour un
	serveur cible spécifique. La valeur doit être au minimum 512 ou définie
	à 0 pour la valeur par défaut du système de 8192.
    
    
    
    responsefieldsize
        8192
	Contrôle la taille du tampon pour le champ de la réponse mandatée.
	Cette taille doit être au moins égale à la taille attendue du plus grand
	en-tête d'une réponse mandatée. Une valeur de 0 implique l'utilisation
	de la valeur par défaut du système, à savoir 8192 octets.
    
	Disponible à partir de la version 2.4.34 du serveur HTTP Apache.
    
    
    
    keepalive
        Off
        
    Cette clé doit être utilisée lorsque vous avez un pare-feu
	entre Apache httpd et le serveur d'arrière-plan, et si ce dernier tend
	à interrompre les connexions inactives. Cette clé va faire en
	sorte que le système d'exploitation envoie des messages
	KEEP_ALIVE sur chacune des connexions inactives et
	ainsi éviter la	fermeture de la	connexion par le pare-feu.
	Pour conserver les connexions persistantes, definissez cette
	propriété à On.
    
    
    La fréquence de vérification des connexions TCP persistantes
    initiale et subséquentes dépend de la configuration globale de l'OS,
    et peut atteindre 2 heures. Pour être utile, la fréquence configurée
    dans l'OS doit être inférieure au seuil utilisé par le pare-feu.
    

    
    
    
    lbset
        0
        Définit le groupe de répartition de charge dont le serveur cible
	est membre. Le répartiteur de charge va essayer tous les membres
	d'un groupe de répartition de charge de numéro inférieur avant
	d'essayer ceux dont le groupe possède un numéro supérieur.
    
    
    
    ping
        0
        Avec la clé Ping, le serveur web va "tester" la connexion
	vers le serveur d'arrière-plan avant de transmettre la requête.
	Avec AJP, mod_proxy_ajp envoie une requête
	CPING sur la connexion ajp13 (implémenté sur Tomcat
	3.3.2+, 4.1.28+ et 5.0.13+). Avec HTTP,
	mod_proxy_http envoie 100-Continue
	au serveur d'arrière-plan (seulement avecHTTP/1.1 - pour les
	serveurs d'arrière-plan non HTTP/1.1, cette clé ne produit
	aucun effet). Dans les deux cas, ce paramètre correspond au
	délai en secondes pour l'attente de la réponse. Cette
	fonctionnalité a été ajoutée pour éviter les problèmes avec les
	serveurs d'arrière-plan bloqués ou surchargés.

	Le trafic
	réseau peut s'en trouver augmenté en fonctionnement normal, ce
	qui peut poser problème, mais peut s'en trouver diminué dans les
	cas où les noeuds de cluster sont arrêtés ou
	surchargés. Le délai peut
	aussi être défini en millisecondes en ajoutant le suffixe
	ms.
    
    
    
    receivebuffersize
        0
        Définit la taille du tampon réseau explicite (TCP/IP) pour
	les connexions mandatées. Cette clé vous permet d'outrepasser la
	directive ProxyReceiveBufferSize pour un
	serveur cible spécifique. Sa valeur doit être au minimum 512 ou définie
	à 0 pour la valeur par défaut du système.
    
    
    
    redirect
        -
        Route pour la redirection du serveur cible. Cette valeur est en
	général définie dynamiquement pour permettre une suppression
	sécurisée du noeud du cluster. Si cette clé est définie, toutes
	les requêtes sans identifiant de session seront redirigées vers
	le membre de groupe de répartition de charge dont la route
	correspond à la valeur de la clé.
    
    
    
    retry
        60
        Délai entre deux essais du serveur cible du jeu de connexions en
	secondes. Si le serveur cible du jeu de connexions vers le serveur
	d'arrière-plan est dans un état d'erreur, Apache httpd ne redirigera
	pas de requête vers ce serveur avant l'expiration du délai
	spécifié. Ceci permet d'arrêter le serveur d'arrière-plan pour
	maintenance, et de le remettre en ligne plus tard. Une valeur de
	0 implique de toujours essayer les serveurs cibles dans un état d'erreur
	sans délai.
    
    
    
    route
        -
        La route du serveur cible lorsqu'il est utilisé au sein d'un
	répartiteur de charge. La route est une valeur ajoutée à
	l'identifiant de session.
    
    
    
    status
        -
        Valeur constituée d'une simple lettre et définissant l'état
	initial de ce serveur cible.
	 
    
         
    D: le serveur cible est désactivé et n'accepte aucune requête.
    
         
    S: le serveur cible est arrêté.
    
         
    I: le serveur cible est en mode "erreurs ignorées",
	 et sera toujours considéré comme disponible.
    
	 
    R: Le serveur cible sert de remplaçant à
	 chaud. Lorsqu'un serveur cible avec un lbset donné est inutilisable
	 (maintenance, arrêt, en erreur, etc...), un serveur de remplacement à
	 chaud libre de même lbset sera utilisé à sa place. Les remplaçants à
	 chaud permettent de s'assurer qu'un nombre déterminé de serveurs cibles
	 sera toujours disponible pour un répartiteur de charge.
    
         
    H: le serveur cible est en mode d'attente et ne sera
	 utilisé que si aucun autre serveur ou remplaçant à chaud n'est
	 disponible dans le jeu de serveurs cibles.
    
         
    E: le serveur cible est en erreur.
    
         
    N: le serveur cible est en mode vidage, n'acceptera que
	 les sessions persistantes qui lui appartiennent, et refusera
	 toutes les autres requêtes.
    
        
    
	Une valeur d'état peut être définie (ce qui
	correspond au comportement par défaut) en préfixant la valeur

	valeur 'S-E' définit l'état de ce serveur cible à "arrêté" et supprime
	le drapeau "en-erreur".
    
    
    
    timeout
        ProxyTimeout
        Délai d'attente de la connexion en secondes. Le nombre de
	secondes pendant lesquelles Apache httpd attend l'envoi de

    ttl
        -
        Durée de vie des connexions inactives et des entrées du pool

    Si l'URL de la directive Proxy débute par
    balancer:// (par exemple:
    balancer://cluster, toute information relative au
    chemin est ignorée), alors un serveur cible virtuel ne communiquant pas
    réellement avec le serveur d'arrière-plan sera créé. Celui-ci sera
    en fait responsable de la gestion de plusieurs serveurs cibles "réels". Dans
    ce cas, un jeu de paramètres particuliers s'applique à ce serveur cible
    virtuel. Voir mod_proxy_balancer pour plus
    d'informations à propos du fonctionnement du répartiteur de
    charge.
    
    
    
    Paramètres du répartiteur
    
    
    
    
    Paramètre
        Défaut
        Description
    
    
    lbmethod
        byrequests
        Méthode de répartition de charge utilisée. Permet de
	sélectionner la méthode de planification de la répartition de
	charge à utiliser. La valeur est soit byrequests,
	pour effectuer un décompte de requêtes pondérées, soit
	bytraffic, pour effectuer une répartition en
	fonction du décompte des octets transmis, soit
	bybusyness, pour effectuer une répartition en
	fonction des requêtes en attente. La valeur par défaut est
	byrequests.
    
    
    
    maxattempts
        1 de moins que le nombre de workers, ou 1 avec un seul
	worker
        Nombre maximum d'échecs avant abandon.
    
    
    
    nofailover
        Off
        Si ce paramètre est défini à On, la session va
	s'interrompre si le serveur cible est dans un état d'erreur ou
	désactivé. Définissez ce paramètre à On si le serveur
	d'arrière-plan ne supporte pas la réplication de session.
    
    
    
    stickysession
        -
        Nom de session persistant du répartiteur. La valeur est
	généralement du style JSESSIONID ou
	PHPSESSIONID, et dépend du serveur d'application
	d'arrière-plan qui supporte les sessions. Si le serveur
	d'application d'arrière-plan utilise un nom différent pour
	les cookies et les identifiants codés d'URL (comme les
	conteneurs de servlet), séparez-les par le caractère '|'. La
	première partie contient le cookie et la seconde le chemin.
    
	Disponible depuis la version 2.4.4 du serveur HTTP Apache.
    
    
    
    stickysessionsep
        "."
        Définit le caractère de séparation dans le cookie de
	session. Certains serveurs d'application d'arrière-plan
	n'utilisent pas le caractère '.' comme séparateur. Par exemple
	le serveur Oracle Weblogic utilise le caractère '!'. Cette
	option permet d'attribuer au caractère de séparation la valeur
	appropriée. Si elle est définie à 'Off', aucun caractère de
	séparation n'est utilisé.
    
    
    
    scolonpathdelim
        Off
        Si ce paramètre est défini à On, le caractère
	';' sera utilisé comme séparateur de chemin de session
	persistante additionnel. Ceci permet principalement de simuler
	le comportement de mod_jk lorsqu'on utilise des chemins du style
	JSESSIONID=6736bcf34;foo=aabfa.
    
    
    
    timeout
        0
        Délai du répartiteur en secondes. Si ce paramètre est
	défini, sa valeur correspond à la durée maximale d'attente pour
	un serveur cible libre. Le comportement par défaut est de ne pas
	attendre.
    
    
    
    failonstatus
        -
        Une liste de codes d'état HTTP séparés par des virgules. Si
	ce paramètre est présent, le worker se mettra en erreur si le
	serveur d'arrière-plan renvoie un des codes d'état spécifiés
	dans la liste. La récupération du worker s'effectue comme dans
	le cas des autres erreurs de worker.
    
    
    
    failontimeout
        Off
        Si ce paramètre est défini à "On", un délai d'attente
	dépassé en entrée/sortie après envoi d'une requête au serveur
	d'arrière-plan va mettre le processus en état d'erreur. La
	sortie de cet état d'erreur se passe de la même façon que pour
	les autres erreurs.
    
	Disponible à partir de la version 2.4.5 du serveur HTTP Apache.
    
    
    
    nonce
        <auto>
        Le nombre à usage unique de protection utilisé dans la page
	de l'application balancer-manager. Par défaut, la
	protection de la page est assurée par un nombre à usage unique
	automatique à base d'UUID. Si une valeur est précisée, elle sera
	utilisée comme nombre à usage unique. La valeur
	None désactive la vérification du nombre à usage
	unique.
    
    Note
    
      
    En plus du nombre à usage unique, la page de l'application
      balancer-manager peut être protégée par une ACL.
    
    
    
     
    
    
    growth
        0
        Nombre de membres supplémentaires que l'on peut ajouter à ce
	répartiteur en plus de ceux définis au niveau de la
	configuration.
    
    
    
    forcerecovery
        On
        Force la relance immédiate de tous les membres sans tenir
	compte de leur paramètre retry dans le cas où ils sont tous en
	état d'erreur. Il peut cependant arriver qu'un membre déjà
	surchargé entre dans une situation critique si la relance de
	tous les membres est forcée sans tenir compte du paramètre retry
	de chaque membre. Dans ce cas, définissez ce paramètre à
	Off.
    
	Disponible depuis la version 2.4.2 du serveur HTTP Apache.

    La définition de remplaçants à chaud permet de s'assurer qu'un nombre

    BalancerMember ajp://1.2.3.5:8009
    # Les serveurs ci-dessous sont des remplaçants à chaud. Pour chaque serveur
    # ci-dessus qui viendrait à être inutilisable (maintenance, arrêt, non
    # contactable, en erreur, etc...), un de ces remplaçants à chaud prendra sa
    # place. Deux serveurs seront toujours disponibles pour traiter une requête
    # (à moins qu'un ou plusieurs remplaçant à chaud soit lui aussi
    # indisponible).
    BalancerMember ajp://1.2.3.6:8009 status=+R
    BalancerMember ajp://1.2.3.7:8009 status=+R
</Proxy>
    


    
    Configuration d'un serveur cible de réserve qui ne sera utilisé que si
    aucun autre serveur cible ou remplaçant à chaud n'est disponible dans le jeu
    de serveurs cibles :
    
    
    ProxyPass "/" "balancer://hotcluster/"
<Proxy "balancer://hotcluster">
    BalancerMember "ajp://1.2.3.4:8009" loadfactor=1

    ProxySet lbmethod=bytraffic
</Proxy>
    


    
    Mots-clés additionnels de ProxyPass
    

    
    Normalement, mod_proxy va mettre sous leur forme canonique les
    URLs traitées par ProxyPass. Mais ceci peut être incompatible avec
    certains serveurs d'arrière-plan, et en particulier avec ceux qui
    utilisent PATH_INFO. Le mot-clé optionnel
    nocanon modifie ce comportement et permet de transmettre
    le chemin d'URL sous sa forme brute au serveur d'arrière-plan. Notez
    que ceci peut affecter la sécurité de votre serveur d'arrière-plan,
    car la protection limitée contre les attaques à base d'URL que
    fournit le mandataire est alors supprimée.
    

    
    Par défaut, mod_proxy inclut la chaîne de paramètres lors de la
    génération de la variable d'environnement
    SCRIPT_FILENAME. Le mot-clé optionnel noquery
    (disponible à partir de la version 2.4.1) permet d'exclure cette
    chaîne.
    

    
    Lorsque la directive ProxyPass est utilisée à l'intérieur d'une
    section <Location>, le premier argument est omis et le répertoire
    local est obtenu à partir de la section <Location>. Il en sera de même dans une
    section <LocationMatch> ; cependant, ProxyPass
    n'interprète pas les expressions rationnelles, et il sera ici
    nécessaire d'utiliser la directive
    ProxyPassMatch à la place.
    

    
    Cette directive ne peut pas être placée dans une section
    <Directory> ou
    <Files>.
    

    
    Si vous avez besoin d'un configuration de mandataire inverse plus
    souple, reportez-vous à la documentaion de la directive RewriteRule et son drapeau
    [P].
    

    
    Le mot-clé optionnel interpolate, en combinaison avec la directive
    ProxyPassInterpolateEnv, permet à ProxyPass
    d'interpoler les variables d'environnement à l'aide de la syntaxe
    ${VARNAME}. Notez que de nombreuses variables
    d'environnement standard dérivées de CGI n'existeront pas lorsque
    l'interpolation se produit ; vous devrez alors encore avoir avoir
    recours à mod_rewrite pour des règles
    complexes. Notez aussi que l'interpolation n'est supportée dans
    la partie protocole/hostname/port d'une URL que pour les variables qui sont
    disponibles au moment où la directive est interprétée (comme pour la
    directive Define). La détermination
    dynamique de ces champs peut être effectuée à l'aide de
    mod_rewrite, et l'exemple suivant décrit comment utiliser
    mod_rewrite pour définir dynamiquement le protocole à http
    ou https :
    

    
    RewriteEngine On

RewriteCond "%{HTTPS}" =off
RewriteRule "". "-" [E=protocol:http]
RewriteCond "%{HTTPS}" =on
RewriteRule "." "-" [E=protocol:https]

RewriteRule "^/mirror/foo/(.*)" "%{ENV:protocol}://backend.example.com/$1" [P]
ProxyPassReverse  "/mirror/foo/" "http://backend.example.com/"
ProxyPassReverse  "/mirror/foo/" "https://backend.example.com/"

    Compatibilité:Disponible à partir de la version 2.4.5 du serveur
HTTP Apache.
    

    
        
    Cette directive permet à un serveur virtuel d'hériter des
	directives ProxyPass définies
	au niveau du serveur principal. Si vous utilisez la fonctionnalité de
	modifications dynamiques du Balancer Manager, cette directive peut
	causer des problèmes et des comportements inattendus et doit donc
	être désactivée.
    
        
    Les valeurs définies au niveau du serveur principal
	constituent les valeurs par défaut pour tous les serveurs virtuels.
    
        
    La désactivation de ProxyPassInherit désactive aussi la
	directive BalancerInherit.

    Module:mod_proxy
    

    Compatibilité:Disponible depuis la version 2.2.9 d'Apache
    

    
    
    Cette directive, ainsi que l'argument interpolate des
    directives ProxyPass,
    ProxyPassReverse,
    ProxyPassReverseCookieDomain et
    ProxyPassReverseCookiePath, permet de
    configurer dynamiquement un mandataire inverse à l'aide de
    variables d'environnement, ces dernières pouvant être définies par un
    autre module comme mod_rewrite. Elle affecte les
    directives ProxyPass,
    ProxyPassReverse,
    ProxyPassReverseCookieDomain, et
    ProxyPassReverseCookiePath, en leur indiquant
    de remplacer la chaîne ${nom_var} dans les directives
    de configuration par la valeur de la variable d'environnement
    nom_var (si l'option interpolate est
    spécifiée).
    
    
    La partie protocole/hostname/port de ProxyPass
    peut contenir des variables, mais seulement celles qui sont accessibles au
    moment où la directive est interprétée (similairement à la directive
    Define). Pour tous les autres cas,
    utilisez plutôt mod_rewrite.
     
    
    Avertissement concernant les performances
    
    
    Laissez cette directive à off, à moins que vous n'en ayez réellemnt
    besoin ! Par exemple, ajouter des variables à
    ProxyPass peut entraîner l'utilisation des serveurs
    d'arrière-plan de mod_proxy configurés par défaut, et ceux-ci ne permettent
    pas un réglage fin comme la réutilisation des connexions, entre
    autres...).

    Directive ProxyPassMatch
    

    

    Description:Fait correspondre des serveurs distants dans l'espace d'URL
du serveur local en utilisant des expressions rationnelles
    

    Syntaxe:ProxyPassMatch [regex] !|url
[clé=valeur
	[clé=valeur ...]]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    Cette directive est identique à la directive ProxyPass, mais fait usage des
    expressions rationnelles, au lieu d'une simple comparaison de
    préfixes. L'expression rationnelle spécifiée est comparée à
    l'url, et si elle correspond, le serveur va substituer
    toute correspondance entre parenthèses dans la chaîne donnée et
    l'utiliser comme nouvelle url.
    

    
    Note : Cette directive ne peut pas être
    utilisée dans un contexte de niveau répertoire.
    

    
    Supposons que le serveur local a pour adresse
    http://example.com/ ; alors
    

    
    ProxyPassMatch "^(/.*\.gif)$" "http://backend.example.com/$1"
    


    
    va provoquer la conversion interne de la requête locale
    http://example.com/foo/bar.gif en une requête mandatée
    pour http://backend.example.com/foo/bar.gif.
    

    
    Note
    
      
    L'argument URL doit pouvoir être interprété en tant qu'URL
      avant les substitutions d'expressions rationnelles (et
      doit aussi l'être après). Ceci limite les correspondances que vous
      pouvez utiliser. Par exemple, si l'on avait utilisé
    
      
            ProxyPassMatch "^(/.*\.gif)$"
	"http://backend.example.com:8000$1"
    

      
    dans l'exemple précédent, nous aurions provoqué une erreur de
      syntaxe au démarrage du serveur. C'est une bogue (PR 46665 dans
      ASF bugzilla), et il est possible de la contourner en reformulant
      la correspondance :
    
      
    ProxyPassMatch "^/(.*\.gif)$" "http://backend.example.com:8000/$1"
    

    
    

    
    Le drapeau ! vous permet de ne pas mandater un
    sous-répertoire donné.
    

    
    Dans une section <LocationMatch>, le premier argument est
    omis et l'expression rationnelle est obtenue à partir de la directive
    <LocationMatch>.
    

    
    Si vous avez besoin d'une configuration du mandataire inverse
    plus flexible, voyez la directive RewriteRule avec le drapeau
    [P].
    

    
    
 	
    Substitution par défaut
    
 	
    Lorsque le paramètre URL n'utilise pas de références arrières
	dans l'expression rationnelle, l'URL originale sera ajoutée au
	paramètre URL.
 	
    
 	
    

    
    
      
    Avertissement à propos de la sécurité
    
      
    Lors de la construction de l'URL cible de la règle, il convient
      de prendre en compte l'impact en matière de sécurité qu'aura le
      fait de permettre au client d'influencer le jeu d'URLs pour
      lesquelles votre serveur agira en tant que mandataire.
      Assurez-vous que la partie protocole://nom-serveur de l'URL soit
      fixe, ou ne permette pas au client de l'influencer induement.

    Directive ProxyPassReverse
    

    

    Description:Ajuste l'URL dans les en-têtes de la réponse HTTP envoyée
par un serveur mandaté en inverse
    

    Syntaxe:ProxyPassReverse [chemin] url
[interpolate]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    Cette directive permet de faire en sorte qu'Apache httpd ajuste l'URL
    dans les en-têtes Location,
    Content-Location et URI des réponses de
    redirection HTTP. Ceci est essentiel lorsqu'Apache httpd est utilisé en
    tant que mandataire inverse (ou passerelle), afin d'éviter de
    court-circuiter le mandataire inverse suite aux redirections HTTP
    sur le serveur d'arrière-plan qui restent derrière le mandataire
    inverse.
    

    
    Seuls les en-têtes de réponse HTTP spécialement mentionnés
    ci-dessus seront réécrits. Apache httpd ne réécrira ni les autres en-têtes
    de réponse, ni par défaut les références d'URLs dans les pages HTML. Cela
    signifie que dans le cas où un contenu mandaté contient des
    références à des URLs absolues, elles court-circuiteront le
    mandataire. Pour réécrire un contenu HTML afin qu'il corresponde au
    mandataire, vous devez charger et activer le module
    mod_proxy_html.
    
    

    
    chemin est le nom d'un chemin virtuel local.
    url est une URL partielle pour le serveur distant. Ces
    paramètres s'utilisent de la même façon qu'avec la
    directive ProxyPass.
    

    
    Supposons par exemple que le serveur local a pour adresse
    http://example.com/ ; alors
    

    
    ProxyPass         "/mirror/foo/" "http://backend.example.com/"
ProxyPassReverse  "/mirror/foo/" "http://backend.example.com/"
ProxyPassReverseCookieDomain  "backend.example.com" "public.example.com"
ProxyPassReverseCookiePath  "/"  "/mirror/foo/"
    


    
    ne va pas seulement provoquer la conversion interne d'une requête
    locale pour http://example.com/mirror/foo/bar en une
    requête mandatée pour http://backend.example.com/bar
    (la fonctionnalité fournie par ProxyPass). Il va
    aussi s'occuper des redirections que le serveur
    backend.example.com envoie lorsqu'il redirige
    http://backend.example.com/bar vers
    http://backend.example.com/quux. Apache
    httpd corrige ceci en http://example.com/mirror/foo/quux
    avant de faire suivre la redirection HTTP au client. Notez que le
    nom d'hôte utilisé pour construire l'URL est choisi en respectant la
    définition de la directive UseCanonicalName.
    

    
    Notez que la directive ProxyPassReverse
    peut aussi être utilisée en conjonction avec la
    fonctionnalité de mandataire
    (RewriteRule ...  [P]) du module
    mod_rewrite, car elle ne dépend pas d'une directive
    ProxyPass
    correspondante.
    

    
    Le mot-clé optionnel interpolate, en
    combinaison avec la directive
    ProxyPassInterpolateEnv, permet
    l'interpolation des variables d'environnement spécifiées en
    utilisant le format ${VARNAME} Notez que l'interpolation
    n'est pas supportée dans la partie protocole d'une URL.
    
    

    
    Lorsque cette directive est utilisée dans une section <Location>, le premier
    argument est omis et le répertoire local est obtenu à partir de
    l'argument de la directive <Location>. Il en est de même à l'intérieur
    d'une section <LocationMatch>, mais le résultat ne sera
    probablement pas celui attendu car ProxyPassReverse va interpréter
    l'expression rationnelle littéralement comme un chemin ; si besoin
    est dans ce cas, définissez la directive ProxyPassReverse en dehors
    de la section, ou dans une section <Location> séparée.
    

    
    Cette directive ne peut pas être placée dans une section
    <Directory> ou
    <Files>.

    L'utilisation de cette directive est similaire à celle de la
directive ProxyPassReverse,

réécrit la chaîne correspondant au domaine dans les en-têtes
Set-Cookie.

chemin-public [interpolate]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy
    

    

    
Cette directive s'avère utile en conjonction avec la directive
ProxyPassReverse dans les
situations où les chemins d'URL d'arrière-plan correspondent à des
chemins publics sur le mandataire inverse. Cette directive permet de
réécrire la chaîne path dans les en-têtes
Set-Cookie. Si le début du chemin du cookie correspond à
chemin-interne, le chemin du cookie sera remplacé par
chemin-public.

    
Dans l'exemple fourni avec la directive ProxyPassReverse, la directive :

    
    
    ProxyPassReverseCookiePath  "/"  "/mirror/foo/"
    


    
va réécrire un cookie possédant un chemin d'arrière-plan /
(ou /example ou en fait tout chemin)

    Directive ProxyPreserveHost
    

    

    Description:Utilise l'en-tête de requête entrante Host pour la requête
du mandataire
    

    Syntaxe:ProxyPreserveHost On|Off
    

    Défaut:ProxyPreserveHost Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy
    

    Compatibilité:Utilisable
dans un contexte de répertoire depuis la version 2.3.3.
    

    
    
    Lorsqu'elle est activée, cette directive va transmettre l'en-tête
    Host: de la requête entrante vers le serveur mandaté, au lieu du nom
    d'hôte spécifié par la directive ProxyPass.
    

    
    Cette directive est habituellement définie à Off.
    Elle est principalement utile dans les configurations particulières
    comme l'hébergement virtuel mandaté en masse à base de nom, où
    l'en-tête Host d'origine doit être évalué par le serveur
    d'arrière-plan.

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    La directive ProxyReceiveBufferSize permet
    de spécifier une taille de tampon réseau explicite (TCP/IP) pour les
    connexions mandatées HTTP et FTP, afin d'améliorer le débit de
    données. Elle doit être supérieure à 512 ou définie à
    0 pour indiquer que la taille de tampon par défaut du
    système doit être utilisée.
    

    
    Exemple
    ProxyReceiveBufferSize 2048

    Directive ProxyRemote
    

    

    Description:Mandataire distant à utiliser pour traiter certaines
requêtes
    

    Syntaxe:ProxyRemote comparaison serveur-distant
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    Cette directive permet de définir des mandataires distants pour
    ce mandataire. comparaison est soit le nom d'un protocole
    que supporte le serveur distant, soit une URL partielle pour
    laquelle le serveur distant devra être utilisé, soit *
    pour indiquer que le serveur distant doit être utilisé pour toutes
    les requêtes. serveur-distant est une URL partielle
    correspondant au serveur distant. Syntaxe : 
    

    
    
      serveur-distant =
          protocole://nom-serveur[:port]
    
    

    
    protocole est effectivement le protocole à utiliser
    pour communiquer avec le serveur distant ; ce module ne supporte que
    http et https. Lorsqu'on utilise
    https, les requêtes sont redirigées par le mandataire
    distant en utilisant la méthode HTTP CONNECT.
    

    
    Exemple
    ProxyRemote "http://goodguys.example.com/" "http://mirrorguys.example.com:8000"
ProxyRemote "*" "http://cleverproxy.localdomain"
ProxyRemote "ftp" "http://ftpproxy.mydomain:8080"
    

    

    
    Dans la dernière ligne de l'exemple, le mandataire va faire
    suivre les requêtes FTP, encapsulées dans une autre requête mandatée
    HTTP, vers un autre mandataire capable de les traiter.
    

    
    Cette directive supporte aussi les configurations de mandataire
    inverse ; un serveur web d'arrière-plan peut être intégré dans
    l'espace d'URL d'un serveur virtuel, même si ce serveur est caché
    par un autre mandataire direct.

    Directive ProxyRemoteMatch

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    La directive ProxyRemoteMatch est
    identique à la directive ProxyRemote, à l'exception du
    premier argument qui est une expression
    rationnelle à mettre en correspondance avec l'URL de la
    requête.

    Directive ProxyRequests

direct
    

    Syntaxe:ProxyRequests On|Off
    

    Défaut:ProxyRequests Off
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_proxy
    

    
    
    Cette directive permet d'activer/désactiver la fonctionnalité de
    serveur mandataire direct d'Apache httpd. Définir ProxyRequests à
    Off n'interdit pas l'utilisation de la directive
    ProxyPass.
    

    
    Pour une configuration typique de mandataire inverse ou
    passerelle, cette directive doit être définie à
    Off.
    

    
    Afin d'activer la fonctionnalité de mandataire pour des sites
    HTTP et/ou FTP, les modules mod_proxy_http et/ou
    mod_proxy_ftp doivent également être chargés dans le
    serveur.
    

    
    Pour activer la fonctionnalité de mandataire sur les sites chiffrés en HTTPS, le module
    mod_proxy_connect doit également être chargé dans le serveur.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avec la directive
      ProxyRequests avant
      d'avoir sécurisé votre serveur. Les serveurs
      mandataires ouverts sont dangereux non seulement pour votre
      réseau, mais aussi pour l'Internet au sens large.

    Directive ProxySet
    

    

    Description:Définit différents paramètres relatifs à la répartition de
charge des mandataires et aux membres des groupes de répartition de
charge
    

    Syntaxe:ProxySet url clé=valeur [clé=valeur ...]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy
    

    Compatibilité:ProxySet n'est disponible que depuis la version 2.2
du serveur HTTP Apache.
    

    
    
    Cette directive propose une méthode alternative pour définir tout
    paramètre relatif aux répartiteurs de charge et serveurs cibles de
    mandataires normalement définis via la directive ProxyPass. Si elle se trouve dans un
    conteneur <Proxy url de répartiteur|url de
    serveur cible>, l'argument url n'est pas
    nécessaire. Comme effet de bord, le répartiteur ou serveur cible respectif
    est créé. Ceci peut s'avérer utile pour la mise en oeuvre d'un
    mandataire inverse via une directive RewriteRule au lieu de ProxyPass.
    

    
    <Proxy "balancer://hotcluster">
    BalancerMember "http://www2.example.com:8080" loadfactor=1
    BalancerMember "http://www3.example.com:8080" loadfactor=2
    ProxySet lbmethod=bytraffic
</Proxy>
    

    

    
    <Proxy "http://backend">
    ProxySet keepalive=On
</Proxy>
    


    
    ProxySet "balancer://foo" lbmethod=bytraffic timeout=15
    


    
    ProxySet "ajp://backend:7001" timeout=15
    


   
    Avertissement
    
      
    Gardez à l'esprit qu'une même clé de paramètre peut avoir
      différentes significations selon qu'elle s'applique à un
      répartiteur ou à un serveur cible, et ceci est illustré par les deux
      exemples précédents où il est question d'un timeout.

    répartiteur de charge du mandataire doivent être affichées via la
    page d'état du serveur du module mod_status.
    
    
    Note

    Cette directive permet à l'utilisateur de spécifier un délai pour
    les requêtes mandatées. Ceci s'avère utile dans le cas d'un serveur
    d'applications lent et bogué qui a tendance à se bloquer, et si vous
    préférez simplement renvoyer une erreur timeout et abandonner la
    connexion en douceur plutôt que d'attendre jusqu'à ce que le serveur
    veuille bien répondre.

    Module:mod_proxy
    

    
    
    Cette directive permet de contrôler l'utilisation de l'en-tête
    HTTP Via: par le mandataire. Le but recherché est de
    contrôler le flux des requêtes mandatées tout au long d'une chaîne
    de serveurs mandataires. Voir RFC 2616 (HTTP/1.1),
    section 14.45 pour une description des lignes d'en-tête
    Via:.
    

    
      
    
    • Si elle est définie à Off, valeur par défaut, cette
    directive n'effectue aucun traitement particulier. Si une requête ou
    une réponse contient un en-tête Via:, il est transmis
    sans modification.
      • 

    
    • Si elle est définie à On, chaque requête ou réponse
    se verra ajouter une ligne d'en-tête Via: pour le
    serveur courant.
      • 

    
    • Si elle est définie à Full, chaque ligne d'en-tête
    Via: se verra ajouter la version du serveur Apache
    httpd sous la forme d'un champ de commentaire Via:.
      • 

    
    • Si elle est définie à Block, chaque requête
    mandatée verra ses lignes d'en-tête Via: supprimées.
    Aucun nouvel en-tête Via: ne sera généré.

    概要
    

    
    このモジュールは拡張子を使っていろいろな「メタ情報」をファイルに
    関連付けるために使用されます。この情報はドキュメントのファイル名と
    MIME タイプ、言語、文字セット、エンコーディングとを関連付けます。
    この情報はブラウザに送られますし、複数のファイルの中からユーザの好みの
    ものが選ばれるように、コンテントネゴシエーションでも使われます。
    コンテントネゴシエーション
    に関する詳しい情報は mod_negotiation
    をご覧下さい。
    

    
    AddCharset ディレクティブ、
    AddEncoding ディレクティブ、
    AddHandler ディレクティブ、
    AddLanguage ディレクティブ、
    AddType ディレクティブはすべて、
    ファイルの拡張子をメタ情報にマップするために使用されます。
    それぞれ、ドキュメントの文字セット (訳注: charset)、content-encoding,
    content-language, MIME タイプ (content-type) を設定します。
    TypesConfig ディレクティブは拡張子を
    MIME タイプにマップするファイルを指定するために使用されます。
    

    
    さらに、mod_mime はコンテンツを作成、処理する
    ハンドラ と フィルタ
    を設定することができます。AddHandler ディレクティブ、AddOutputFilter ディレクティブ、AddInputFilter ディレクティブは
    ドキュメントを扱うモジュールやスクリプトを制御します。
    MultiviewsMatch ディレクティブは
    これらのディレクティブが指定したファイルの拡張子を
    mod_negotiation が Multiviews のマッチをとるときに
    考慮するようにできます。
    

    
    mod_mime はメタ情報をファイル名と関連付けますが、
    core サーバにはあるコンテナ
    (たとえば, <Location>, <Directory>, <Files>) の中のすべてのファイルを特定の
    メタ情報と関連付けるディレクティブがあります。これらのディレクティブには
    ForceType, SetHandler, SetInputFilter, SetOutputFilter があります。
    コアのディレクティブは mod_mime により定義された
    ファイル名の拡張子のマッピングすべてを上書きします。
    

    
    ファイルのメタ情報を変えても Last-Modified
    ヘッダの値は変わらないことに注意してください。ですから、
    それらを変更した場合は、クライアントやプロキシで以前にキャッシュされた
    コピーがそのときのヘッダとともに使われる可能性があります。
    メタ情報 (言語、コンテントタイプ、文字セット、エンコーディング) を
    変更したときは、すべての訪問者が正しいコンテントヘッダを
    受け取るように、影響を受けるファイルに 'touch' コマンドを実行する
    (最終更新日を更新する) 必要があるかもしれません。
    

    


    top
    

    

    複数の拡張子のあるファイル
    
    
    ファイルは複数の拡張子を持つことができ、拡張子の順番は通常は関係ありません。例えば、ファイル welcome.html.fr
    がコンテントタイプは text/html
    に、言語はフランス語にマップされる場合、welcome.fr.html
    もまったく同じ情報にマップされます。
    同じメタ情報にマップされる拡張子が複数あるときには、言語と
    コンテントエンコーディングを除いて、
    右側にあるものが使用されます。たとえば、.gif が MIME タイプ image/gif にマップされ、.html
    が MIME タイプ text/html
    にマップされる場合は、ファイル welcome.gif.html は
    MIME タイプ text/html に関連付けられます。
    

    
    リソースに複数の言語やエンコーディングを関連付けること
    ができるため、
    言語とコンテントエンコーディングは前のものに追加されていきます。
    たとえば、ファイル welcome.html.en.de は
    Content-Language: en, de と Content-Type:
    text/html として送信されます。
    

    
    複数の拡張子のあるファイルが MIME
    タイプとハンドラの両方に関連付けられているときは注意する必要があります。
    その場合、普通はリクエストがハンドラに関連付けられた
    モジュールによって扱われることになります。たとえば、拡張子
    .imap が (mod_imagemap の) imap-file
    にマップされていて、.html が MIME タイプ text/html
    にマップされているときは、ファイル world.imap.html は
    imap-file ハンドラと text/html MIME
    タイプに関連付けられます。ファイルが処理されるときは imap-file
    ハンドラが使用されますので、そのファイルは mod_imagemap
    のイメージマップファイルとして扱われることになります。
    

    
    ファイル名のドット区切りでの最後の部分を使って、
    特定の部分のメタデータにマッピングしたい場合は、
    Add* ディレクティブは使わないでください。
    たとえば foo.html.cgi を CGI スクリプトとして処理したいけれども、
    bar.cgi.html は CGI スクリプトとしては処理したくない場合、
    AddHandler cgi-script .cgi とする代わりに
    次のようにしてください
    

    
    Configure handler based on final extension only
    
    <FilesMatch \.cgi$>
    
      SetHandler cgi-script
    
    </FilesMatch>
    
    


    top
    

    

    コンテントエンコーディング
    
    
    特定の MIME タイプ
    のファイルはインターネットでの転送を簡単にするために、
    さらに符号化することができます。これは通常は gzip の
    ような圧縮のことを指しますが、pgp のような暗号化や、
    バイナリファイルを ASCII (テキスト) 形式で送るために考案された
    UUencoding のことを指すこともあります。
    

    
    HTTP/1.1 RFC 
    14.11 節では次のように記述されています。
    

    
    
      
    Content-Encoding エンティティヘッダフィールドはメディアタイプの
      修飾子として使われます。それが存在していれば、値はエンティティボディに
      どの追加の符号化が適用されたかを示し、Content-Type ヘッダフィールドに
      書かれているメディアタイプを得るためにどの復号機構を適用すべきか、も
      示していることになります。Content-Encoding は主に、元のメディアタイプの
      同一性を失うことなくドキュメントを圧縮することを可能にするために
      使用されます。
    
    
    

    
    複数のファイル拡張子 (複数の拡張子については 上の節 を参照) 使うことで、
    ファイルのタイプやエンコーディングを指定することが
    できます。
    

    
    たとえば、Microsoft Word のドキュメントがあり、サイズを小さくするために
    pkzip されているとします。.doc 拡張子が Microsoft Word の
    ファイルタイプと関連付けられていて、.zip 拡張子が
    pkzip ファイルエンコーディングと関連付けられていると、ファイル
    Resume.doc.zip は pkzip された Word ドキュメントである
    ということがわかります。
    

    
    クライアントのブラウザにエンコーディング方法を知らせるために、
    Apache はリソースと共に Content-Encoding ヘッダを
    送ります。
    

    
    Content-encoding: pkzip
    

    top
    

    

    文字セットと言語
    
    
    ファイルタイプとファイルエンコーディングの他に重要な情報は
    ドキュメントの書かれている言語と、どの文字セットでファイルが表示
    されるべきか、というものです。たとえば、ドキュメントはベトナムの
    アルファベットやキリル文字で書かれていて、そのように表示される
    必要があるかもしれません。この情報もまた、HTTP ヘッダで
    送信されます。
    

    
    文字セット、言語、エンコーディング、mime タイプはすべて
    コンテントネゴシエーション (mod_negotiation 参照)
    の最中に、複数の文字セット、言語、エンコーディング、MIME タイプからなる
    代替物があるときにどのドキュメントをクライアントに送るのかを
    決定するときに使われます。AddCharset,
    AddEncoding, AddLanguage,
    AddType の各ディレクティブで作成された
    拡張子の関連付け (と MimeMagicFile でリストされている
    拡張子) がこの選択に参加します。AddHandler,
    AddInputFilter,
    AddOutputFilter の
    各ディレクティブでのみ関連付けられている拡張子は
    MultiviewsMatch ディレクティブを
    使うことでマッチの
    処理に含めることも外すこともできます。
    

    
    Charset
    
      
    さらに情報を伝えるために、Apache は文書の言語を
      Content-Language ヘッダで送ることもあります。
      また、情報を正しく表示するために使用すべき文字セットを示すために
      Conten-Type ヘッダに情報を追加することもあります。
    

      
    
        Content-Language: en, fr
    
        Content-Type: text/plain; charset=ISO-8859-1
      
    

      
    言語の指定は二文字の短縮形で行なわれます。charset が
      使用すべき文字セットの名前です。

    AddCharset ディレクティブ
    

    

    説明:ファイル名の拡張子を指定された文字セットにマップする

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:
    

    モジュール:mod_mime
    

    
    
    AddCharset ディレクティブは、
    与えられた拡張子を指定された charset にマップします。charset 
    は、拡張子 extension を含んでいるファイル名の 
    MIME charset
    パラメータです。新しいマッピングは既にある他のマッピングに追加され、同じ拡張子
    extension のためのマッピングを上書きします。
    

    
    例
    
      AddLanguage ja .ja
    
      AddCharset EUC-JP .euc
    
      AddCharset ISO-2022-JP .jis
    
      AddCharset SHIFT_JIS .sjis
    
    

    
    この場合、ドキュメント xxxx.ja.jis は charset が
    ISO-2022-JP の日本語のドキュメントとして扱われます
    (xxxx.jis.ja も同様)。AddCharset
    ディレクティブは、ドキュメントが適切に解釈され表示されるように、
    ドキュメントの charset の情報をクライアントに教えるために役に立ちます。
    また、サーバがクライアントの charset
    の優先度に基づいて複数のドキュメントの中からドキュメントを選ぶコンテントネゴシエーションのためにも役に立ちます。
    

    
    引数 extensionは大文字小文字を区別せず、
    最初のドットはあってもなくても構いません。
    ファイル名は複数の拡張子を持つことができ、
    extensionはそれぞれと比較されます。

    AddEncoding ディレクティブ

    ステータス:
    

    モジュール:mod_mime
    

    
    
    AddEncoding ディレクティブは、
    与えられた拡張子を指定されたエンコーディングにマップします。
    MIME-enc は、拡張子 extension
    を含んだドキュメントに使用する MIME エンコーディングです。
    この新しいマッピングは既にある他のマッピングに追加され、
    同じ拡張子 extension のためのマッピングを上書きします。
    

    
    例
    
      AddEncoding x-gzip .gz
    
       AddEncoding x-compress .Z    
    
    

    
    これは、拡張子 .gz を含むファイル名が x-gzip
    エンコーディングを使ってエンコードされていることと、拡張子 .Z
    を含むファイル名が x-compress
    でエンコードされていることを指定します。
    

    
    古いクライアントは x-zip と x-compress
    が返ってくることを期待しますが、標準規格ではそれぞれ
    gzip と compress
    と等価であることになっています。Apache
    は、コンテントエンコーディングの比較をするときには、先頭にある
    x- を無視します。Apache
    がエンコーディング付きで応答を返すときは、クライアントが要求した形式
    (すなわち、x-foo や foo)
    を使用します。要するに、この二つのエンコーディングの場合は常に
    x-gzip と x-compress
    を使うべきである、ということです。deflate
    のようなより新しいエンコーディングでは、x-
    なしで指定してください。

    ".cgi" で終わるファイルを CGI
    スクリプトとして扱いたいときは、以下の設定をします。
    

    
    
      AddHandler cgi-script .cgi
    
    

    
    これを httpd.conf ファイルに記述することで、拡張子

    AddLanguage ディレクティブは、与えられた拡張子を指定された
    content language にマップします。MIME-lang は、拡張子
    extension を含んでいるファイル名の MIME における言語です。
    この新しいマッピングは既にあるマッピングに追加され、同じ拡張子
    extension のためのマッピングを上書きします。
    

    
    例
    
      AddEncoding x-compress .Z
    
      AddLanguage en .en
    
      AddLanguage fr .fr
    
    

    
    この場合、xxxx.en.Z ドキュメントは compress
    された英語のドキュメントとして扱われます (xxxx.Z.en
    も同様)。content language はクライアントに通知されますが、
    ブラウザがこの情報を使うことはおそらくありません。
    AddLanguage
    ディレクティブは、サーバがクライアントの言語の優先度に基づいて複数の
    ドキュメントの中からドキュメントを選ぶコンテントネゴシエーションのためにより役に立ちます。
    

    
    複数の言語が同じ拡張子に割り当てられているときは、
    最後のものが使用されます。すなわち、次のような場合、
    

    
    
      AddLanguage en .en
    
      AddLanguage en-gb .en
    
      AddLanguage en-us .en

    DefaultLanguage ディレクティブは、Apache
    がディレクティブのスコープ (例えば、その時点の
    <Directory>
    の範囲) にある、明示的な言語拡張子
    (AddLanguage で設定される
    .fr や .de) のない全てのファイルを、指定された
    MIME-lang 言語であるとみなすようにします。
    これにより、すべてのファイル名を変えることなく、
    ディレクトリがオランダ語のコンテントを含んでいる、
    というようなことを指定することができます。
    拡張子を使用して言語を指定する方法と違い、
    DefaultLanguage
    は一つの言語しか指定できないことに注意してください。
    

    
    DefaultLanguage
    ディレクティブが有効でなく、ファイルに
    AddLanguage
    で設定された言語の拡張子がないときは、
    ファイルには言語属性がないとみなされます。

    デフォルト:ModMimeUsePathInfo Off
    

    コンテキスト:ディレクトリ
    

    ステータス:
    

    モジュール:mod_mime
    

    互換性:Apache 2.0.41 以降
    

    
    
    ModMimeUsePathInfo ディレクティブは、
    mod_mime の持つディレクティブを
    リクエストに適用させるために、ファイル名と path_info URL 
    コンポーネントを結合させるために使用します。
    デフォルトでは「 Off 」で、path_info
    コンポーネントは無視されます。
    

    
    このディレクティブは、バーチャルファイルシステムを使用している際に
    推奨されるディレクティブです。
    

    
    例
    
      ModMimeUsePathInfo On
    
    

    
    /bar が存在して (foo.shtml は存在しない)
    ModMimeUsePathInfo が On であるとして、
    /bar/foo.shtml に対するリクエストを発行した場合、
    mod_mime は入ってきたリクエストを
    /bar/foo.shtml として扱い、
    AddOutputFileter INCLUDES .shtml のようなディレクティブは
    INCLUDES フィルタをリクエストに付加させます。
    ModMimeUsePathInfo が設定されなければ、
    INCLUDES フィルタは付加されません。

    MultiviewsMatch ディレクティブ
    

    

    説明:MultiViews でのマッチングの検索に含ませる
ファイルのタイプを指定する
    

    構文:MultiviewsMatch Any|NegotiatedOnly|Filters|Handlers
[Handlers|Filters]
    

    デフォルト:MultiviewsMatch NegotiatedOnly

    上書き:FileInfo
    

    ステータス:
    

    モジュール:mod_mime
    

    互換性:2.0.26 以降で使用可能
    

    
    
    MultiviewsMatch を使用することで、
    mod_negotiation の
    Multiviews に 3 種類の異なる挙動をさせることができます。
    Multiviews を使用すると、ファイル (例 index.html)
    に対するリクエストに対して、ネゴシエーションする拡張子がベースに付いたもの
    (index.html.en, index.html.fr や
    index.html.gz)
    をマッチさせることができます。
    

    
    NegotiatedOnly オプションでは、ベース名に続く拡張子全てが
    コンテントネゴシエーションで mod_mime
    が認識する拡張子 (例 文字セット、コンテントタイプ、言語やエンコーディング)
    に関連付けられていなければなりません。これは副作用の最も少ない
    最も的確な実装で、デフォルトになっています。
    

    
    ハンドラとフィルタの両方もしくは片方と関連付けられた拡張子を含めるには、
    MultiviewsMatch ディレクティブに Handlers,
    Filters またはその両方のオプションをセットします。
    もし他の条件が同じであれば、最も小さいファイルが送信されます。
    例えば、500 文字の index.html.cgi と 1000 バイトの 
    index.html.pl であれば、.cgi 
    のファイルが優先されます。.asis ファイルを利用しているユーザは、
    .asis ファイルが asis-handler に関連付けられているときには、
    ハンドラオプションの使用を好むでしょう。
    

    
    最後に、mod_mime が認識しない拡張子であろうとも、
    どんな拡張子でもマッチさせる Any が使用できます。
    この挙動は Apache 1.3 のときと同じもので、予期しない動作、例えば .old や
    .bak ファイルといったウェブマスタが送信を意図していない
    ファイルを送信する、といった動作を行なう可能性があります。
    

    
    例えば次の設定では、ハンドラやフィルタが Multiviews に参加することが
    できますし、未知のファイルは除外することができます。
    

    
    
      MultiviewsMatch Handlers Filters

    これにより、サブディレクトリにある .htaccess
    ファイルが親ディレクトリやサーバの設定ファイルから継承した関連付けを
    取り消すことができます。

        RemoveEncoding .gz
    
          
      </Files>
    
    

    
    これは、foo.gz は gzip
    でエンコードされていることを指定しますが、foo.gz.asc
    はエンコードされていないプレーンテキストの
    ファイルであるということを指定します。
    

    
    注意
    
      
    RemoveEncoding は
      AddEncoding
      ディレクティブの後で処理されますので、
      同じディレクトリの設定中に両方が現れると、
      後者の効果が打ち消される可能性があります。

    /foo/bar/.htaccess:

    Examples
    

    
      
      
    1. 
        Log message after request to /foo/* is processed:

        
      <Location "/foo/">
  LogMessage "/foo/ has been requested"
</Location>
      

      
      2. 

      
    2. 
        Log message if request to /foo/* is processed in a sub-request:
        
      <Location "/foo/">
  LogMessage "subrequest to /foo/" hook=type_checker "expr=-T %{IS_SUBREQ}"
</Location>
      


        The default log_transaction hook is not executed for sub-requests,
        therefore we have to use a different hook.
      
      3. 


      
    3. 
        Log message if an IPv6 client causes a request timeout:
        
      LogMessage "IPv6 timeout from %{REMOTE_ADDR}" "expr=-T %{IPV6} && %{REQUEST_STATUS} = 408"
      

        Note the placing of the double quotes for the expr= argument.
      
      4. 

      
    4. 
        Log the value of the "X-Foo" request environment variable in each
        stage of the request:
        
      <Location "/">
  LogMessage "%{reqenv:X-Foo}" hook=all
</Location>
      

        Together with microsecond time stamps in the error log,
        hook=all also lets you determine the times spent
        in the different parts of the request processing.

    Context:directory
    

    Status:Experimental
    

    Module:mod_log_debug
    

    
    
    This directive causes a user defined message to be logged to the
    error log. The message can use variables and functions from the
    ap_expr syntax. References to HTTP headers
    will not cause header names to be added to the Vary header. The
    messages are logged at loglevel info.
    

    
    The hook specifies before which phase of request processing the message
    will be logged. The following hooks are supported:
    

    
    Name
    

    pre_translate_name
    

    translate_name
    

    type_checker
    

    quick_handler

    check_authz
    

    fixups
    

    handler
    

    log_transaction
    

    

    
    The default is log_transaction. The special value
    all is also supported, causing a message to be logged at each
    phase. Not all hooks are executed for every request.
    

    
    The optional expression allows to restrict the message if a
    condition is met. The details of the expression syntax are described in
    the ap_expr documentation. References to HTTP
    headers will not cause the header names to be added to the Vary header.

    Description:Filesystem provider for mod_dav
    

    Status:Extension
    

    Module Identifier:dav_fs_module
    

    Source File:mod_dav_fs.c
    

    Summary
    

    
    This module requires the service of mod_dav. It acts as a support module for mod_dav and provides access to resources located in the
    server's file system. The formal name of this provider is
    filesystem. mod_dav backend providers
    will be invoked by using the Dav
    directive:
    

    
    Example
    Dav filesystem
    

    

    
    Since filesystem is the default provider for
    mod_dav, you may simply use the value
    On instead.

    Status:Extension
    

    Module:mod_dav_fs
    

    
    
    Use the DavLockDB directive to specify
    the full path to the lock database, excluding an extension. If
    the path is not absolute, it will be taken relative to ServerRoot. The implementation of
    mod_dav_fs uses a SDBM database to track user
    locks.
    

    

    
    Example
    DavLockDB "var/DavLock"
    

    

    
    The directory containing the lock database file must be
    writable by the User
    and Group under which
    Apache is running.  For security reasons, you should create a
    directory for this purpose rather than changing the permissions on
    an existing directory.  In the above example, Apache will create
    files in the var/ directory under the ServerRoot with the base filename
    DavLock and extension name chosen by the server.

    Sommaire
    

    
    Ce module permet aux frontaux d'authentification comme
    mod_auth_basic d'authentifier les utilisateurs via
    un annuaire ldap.
    

    
    mod_authnz_ldap supporte les fonctionnalités
    suivantes :
    

    
      
      
    • Support vérifié du OpenLDAP SDK (versions 1.x et
      2.x), du 
      Novell LDAP SDK et du SDK iPlanet
      (Netscape).
      • 

      
    • Implémentation de politiques d'autorisation complexes en les
      définissant via des filtres LDAP.
      • 

      
    • Mise en oeuvre d'une mise en cache des opérations LDAP
      élaborée via mod_ldap.
      • 

      
    • Support de LDAP via SSL (nécessite le SDK Netscape) ou TLS
      (nécessite le SDK OpenLDAP 2.x ou le SDK LDAP Novell).
      • 
    
    

    
    Lorsqu'on utilise mod_auth_basic, ce module est
    invoqué en affectant la valeur ldap à la directive
    AuthBasicProvider.

    Mises en garde à caractère général
    

    Ce module effectue une mise en cache des résultats du processus
d'authentification et d'autorisation en fonction de la configuration du
module mod_ldap. Les modifications effectuées au niveau
du serveur LDAP d'arrière-plan comme les
verrouillages ou révocations d'utilisateurs, les changements de mot de
passe, ou les changements d'appartenance à un groupe (et cette liste
n'est pas exhaustive), ne seront pas immédiatement propagées jusqu'au
serveur HTTP. Consultez les directives du module
mod_ldap pour plus de détails à propos de la
configuration de la mise en cache.

    

    top
    

    

    Mode opératoire
    

    
    L'utilisateur se voit accorder l'accès selon un processus en deux
    phases. La première phase est l'authentification, au cours de
    laquelle le fournisseur d'authentification
    mod_authnz_ldap vérifie que les informations de
    connexion de l'utilisateur sont valides. Elle est aussi connue sous
    le nom de phase de recherche/connexion (NdT : en anglais ou
    dans le code source : search/bind). La deuxième
    phase est l'autorisation, au cours de laquelle
    mod_authnz_ldap détermine si l'utilisateur
    authentifié a la permission d'accéder à la ressource considérée.
    Elle est aussi connue sous le nom de phase de
    comparaison (compare).
    

    
    mod_authnz_ldap comporte un fournisseur
    d'authentification authn_ldap et un gestionnaire d'autorisation
    authz_ldap. Le fournisseur d'authentification authn_ldap peut être
    invoqué en affectant la valeur ldap à la directive
    AuthBasicProvider. Le
    gestionnaire d'autorisation authz_ldap enrichit la liste des types
    d'autorisations de la directive Require en y ajoutant les
    valeurs ldap-user, ldap-dn et
    ldap-group.
    


    La phase d'authentification
    

    
    Au cours de la phase d'authentification,
    mod_authnz_ldap recherche une entrée de l'annuaire
    LDAP qui correspond au nom d'utilisateur fourni par le client HTTP.
    Si une correspondance unique est trouvée,
    mod_authnz_ldap tente de se connecter au serveur
    hébergeant l'annuaire LDAP en utilisant le DN de l'entrée et le mot
    de passe fourni par le client HTTP. Comme ce processus effectue tout
    d'abord une recherche, puis une connexion, il est aussi connu sous
    le nom de phase de recherche/connexion. Voici le détail des étapes
    constituant la phase de recherche/connexion :
    

    
      
      
    1. Confection d'un filtre de recherche en combinant les attribut
      et filtre définis par la directive AuthLDAPURL avec le nom d'utilisateur et le mot de
      passe fournis par le client HTTP.
      2. 

      
    2. Recherche dans l'annuaire LDAP en utilisant le filtre
      confectionné précédemment. Si le résultat de la recherche est
      négatif ou comporte plusieurs entrées, refus ou restriction de
      l'accès.
      3. 

      
    3. Extraction du DN (distinguished name) de l'entrée issue du
      résultat de la recherche, et tentative de connexion au serveur
      LDAP en utilisant ce DN et le mot de passe fournis par le client
      HTTP. Si la connexion échoue, refus ou restriction de
      l'accès.
      4. 
    
    

    
    Les directives utilisées durant la phase de recherche/connexion
    sont les suivantes :
    

    
    
      
      
    
        AuthLDAPURL

        Spécifie le serveur LDAP, le DN de base, l'attribut à
	utiliser pour la recherche, ainsi que les filtres de recherche
	supplémentaires.
      
    

      
    
        AuthLDAPBindDN

        Un DN optionnel pour se connecter durant la phase de
	recherche.
      
    

      
    
        AuthLDAPBindPassword

        Un mot de passe optionnel pour se connecter durant la phase
	de recherche.
      
    
    
    



    La phase d'autorisation
    

    
    Au cours de la phase d'autorisation,
    mod_authnz_ldap tente de déterminer si
    l'utilisateur est autorisé à accéder à la ressource considérée. Une
    grande partie de cette vérification consiste pour
    mod_authnz_ldap en des opérations de comparaison au
    niveau du serveur LDAP. C'est pourquoi cette phase est aussi connue
    sous le nom de phase de comparaison.
    mod_authnz_ldap accepte les directives Require suivantes pour
    déterminer si les informations de connexion permettent d'accorder
    l'accès à l'utilisateur :
    

    
      
      
    • Avec la directive Require ldap-user,
      l'autorisation d'accès est accordée si le nom d'utilisateur
      spécifié par la directive correspond au nom d'utilisateur fourni
      par le client.
      • 

      
    • Avec la directive Require
      ldap-dn, l'autorisation d'accès est accordée si le DN
      spécifié par la directive correspond au DN extrait du résultat de
      la recherche dans l'annuaire LDAP.
      • 

      
    • Avec la directive Require ldap-group,
      l'autorisation d'accès est accordée si le DN extrait du résultat de
      la recherche dans l'annuaire LDAP (ou le nom d'utilisateur fourni
      par le client) appartient au groupe LDAP spécifié par la
      directive, ou éventuellement à un de ses sous-groupes.
      • 

      
    • Avec la directive 
      Require ldap-attribute, l'autorisation d'accès
      est accordée si la valeur de l'attribut extraite de la recherche
      dans l'annuaire LDAP correspond à la valeur spécifiée par la
      directive.
      • 

      
    • Avec la directive 
      Require ldap-filter, l'autorisation d'accès
      est accordée si le filtre de recherche renvoie un objet
      utilisateur unique qui corresponde au DN de l'utilisateur
      authentifié.
      • 

      
    • dans tous les autres cas, refus ou restriction de
      l'accès.
      • 
    
    

    
    Sous réserve du chargement de modules d'autorisation
    supplémentaires, d'autres valeurs de la directive Require peuvent être
    spécifiées.
    

    


    
    Durant la phase de comparaison, mod_authnz_ldap
    utilise les directives suivantes :
    

    
    
      
      
    
        AuthLDAPURL
	

        On utilise l'attribut spécifié dans l'URL pour les
	opérations de comparaison initiées par la directive
	Require ldap-user.
      
    

      
    
        AuthLDAPCompareDNOnServer

        Détermine le comportement de la directive Require
	ldap-dn.
      
    

      
    
        AuthLDAPGroupAttribute

        Détermine l'attribut utilisé pour les opérations de
	comparaison initiées par la directive Require
	ldap-group.
      
    

      
    
        AuthLDAPGroupAttributeIsDN

        Spécifie si l'on doit utiliser le DN ou le nom de
	l'utilisateur lors des opérations de comparaison initiées par la
	directive Require ldap-group.
      
    

      
    
        AuthLDAPMaxSubGroupDepth

        Détermine la profondeur maximale de l'arborescence des
	sous-groupes qui seront évalués au cours des opérations de
	comparaisons initiées par la directive Require
	ldap-group.
      
    

      
    
        AuthLDAPSubGroupAttribute

        Détermine l'attribut à utiliser lors de l'extraction de
	membres de sous-groupes du groupe courant au cours des
	opérations de comparaison initiées par la directive
	Require ldap-group.
      
    

      
    
        AuthLDAPSubGroupClass

        Spécifie les valeurs de classe d'objet LDAP à utiliser pour
	déterminer si les objets extraits de l'annuaire sont bien des
	objets de type groupe (et non des objets de type utilisateur),
	au cours du traitement des sous-groupes initié par la directive
	Require ldap-group.

    Les directives requises
    

    
    Les directives Require d'Apache sont utilisées
    au cours de la phase d'autorisation afin de s'assurer que
    l'utilisateur est autorisé à accéder à une ressource.
    mod_authnz_ldap enrichit la liste des types d'autorisations avec les
    valeurs ldap-user, ldap-dn,
    ldap-group, ldap-attribute et
    ldap-filter. D'autres types d'autorisations sont
    disponibles, sous réserve du chargement de modules d'autorisation
    supplémentaires.
    

    
    Depuis la version 2.4.8, les directives require LDAP supportent
    les expressions.
    


    Require ldap-user
    

    
    La directive Require ldap-user permet de spécifier
    les noms des utilisateurs autorisés à accéder à la ressource.
    Lorsque mod_authnz_ldap a extrait un DN unique de
    l'annuaire LDAP, il effectue une opération de comparaison LDAP en
    utilisant le nom d'utilisateur spécifié par la directive
    Require ldap-user, pour vérifier si ce nom
    d'utilisateur correspond à l'entrée LDAP extraite. On peut accorder
    l'accès à plusieurs utilisateurs en plaçant plusieurs nom
    d'utilisateurs sur la même ligne séparés par des espaces. Si un nom
    d'utilisateur contient des espaces, il doit être entouré de
    guillemets. On peut aussi accorder l'accès à plusieurs utilisateurs
    en utilisant une directive Require ldap-user par
    utilisateur. Par exemple, avec la directive AuthLDAPURL définie à
    ldap://ldap/o=Example?cn (spécifiant donc que l'attribut
    cn sera utilisé pour les recherches), on pourra
    utiliser les directives Require suivantes pour restreindre l'accès
    :
    

    Require ldap-user "Barbara Jenson"
Require ldap-user "Fred User"
Require ldap-user "Joe Manager"
    


    
    De par la manière dont mod_authnz_ldap traite
    cette directive, Barbara Jenson peut s'authentifier comme
    Barbara Jenson, Babs Jenson ou tout autre
    cn sous lequel elle est enregistrée dans l'annuaire
    LDAP. Une seule ligne Require ldap-user suffit pour
    toutes les valeurs de l'attribut dans l'entrée LDAP de
    l'utilisateur.
    

    
    Si l'attribut uid avait été spécifié à la place de
    l'attribut cn dans l'URL précédente, les trois lignes
    ci-dessus auraient pû être condensées en une seule ligne :
    

    Require ldap-user bjenson fuser jmanager
    




    Require ldap-group
    

    
    Cette directive permet de spécifier un groupe LDAP dont les
    membres auront l'autorisation d'accès. Elle prend comme argument le
    DN du groupe LDAP. Note : n'entourez pas le nom du groupe avec des
    guillemets. Par exemple, supposons que l'entrée suivante existe dans
    l'annuaire LDAP :
    

    dn: cn=Administrators, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Barbara Jenson, o=Example
uniqueMember: cn=Fred User, o=Example
    

    
    La directive suivante autoriserait alors l'accès à Fred et
    Barbara :
    

    Require ldap-group cn=Administrators, o=Example
    


    
    Les membres peuvent aussi se trouver dans les sous-groupes du
    groupe LDAP spécifié si la directive AuthLDAPMaxSubGroupDepth a été
    définie à une valeur supérieure à 0. Par exemple, supposons que les
    entrées suivantes existent dans l'annuaire LDAP :
    

    dn: cn=Employees, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Managers, o=Example
uniqueMember: cn=Administrators, o=Example
uniqueMember: cn=Users, o=Example

dn: cn=Managers, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Bob Ellis, o=Example
uniqueMember: cn=Tom Jackson, o=Example

dn: cn=Administrators, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Barbara Jenson, o=Example
uniqueMember: cn=Fred User, o=Example

dn: cn=Users, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Allan Jefferson, o=Example
uniqueMember: cn=Paul Tilley, o=Example
uniqueMember: cn=Temporary Employees, o=Example

dn: cn=Temporary Employees, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Jim Swenson, o=Example
uniqueMember: cn=Elliot Rhodes, o=Example
    

    
    Les directives suivantes autoriseraient alors l'accès à Bob
    Ellis, Tom Jackson, Barbara Jenson, Fred User, Allan Jefferson, et
    Paul Tilley, mais l'interdiraient à Jim Swenson, ou Elliot Rhodes
    (car ils sont situés dans un sous-groupe de niveau de profondeur 2)
    :
    

    Require ldap-group cn=Employees, o=Example
AuthLDAPMaxSubGroupDepth 1
    


    
    Le comportement de cette directive est modifié par les directives
    AuthLDAPGroupAttribute,
    AuthLDAPGroupAttributeIsDN,
    AuthLDAPMaxSubGroupDepth,
    AuthLDAPSubGroupAttribute, et
    AuthLDAPSubGroupClass.
    



    Require ldap-dn
    

    
    La directive Require ldap-dn permet à
    l'administrateur d'accorder l'utorisation d'accès en fonction du DN.
    Elle permet de spécifier un DN pour lequel l'accès est autorisé. Si
    le DN extrait de
    l'annuaire correspond au DN spécifié par la directive Require
    ldap-dn, l'autorisation d'accès est accordée. Note :
    n'entourez pas Le DN de guillemets.
    

    
    La directive suivante accorderait l'accès à un DN spécifique
    :
    

    Require ldap-dn cn=Barbara Jenson, o=Example
    


    
    Le comportement ce cette directive est modifié par la directive
    AuthLDAPCompareDNOnServer.
    



    Require ldap-attribute
    

    
    La directive Require ldap-attribute permet à
    l'administrateur d'accorder l'autorisation d'accès en fonction des
    attributs de l'utilisateur authentifié dans l'annuaire LDAP. Si la
    valeur de l'attribut dans l'annuaire correspond à la valeur
    spécifiée par la directive, l'autorisation d'accès est accordée.
    

    
    La directive suivante accorderait l'autorisation d'accès à tout
    utilisateur dont l'attribut employeeType a pour valeur "actif" :
    

    
    Require ldap-attribute employeeType="active"
    


    
    Plusieurs paires attribut/valeur peuvent être spécifiées par une
    même directive en les séparant par des espaces, ou en définissant
    plusieurs directives Require ldap-attribute. La logique
    sous-jacente à une liste de paires attribut/valeur est une opération
    OU. L'autorisation d'accès sera accordée si au moins une paire
    attribut/valeur de la liste spécifiée correspond à la paire
    attribut/valeur de l'utilisateur authentifié. Si elle contient des
    espaces, la valeur, et seulement la valeur, doit être entourée de
    guillemets.
    

    
    La directive suivante accorderait l'autorisation d'accès à tout
    utilisateur dont l'attribut city aurait pour valeur "San Jose", ou
    donc l'attribut status aurait pour valeur "actif" :
    

    
    Require ldap-attribute city="San Jose" status="active"
    





    Require ldap-filter
    

    
    La directive Require ldap-filter permet à
    l'administrateur d'accorder l'autorisation d'accès en fonction d'un
    filtre de recherche LDAP complexe. L'autorisation d'accès est
    accordée si le DN renvoyé par le filtre de recherche correspond au
    DN de l'utilisateur authentifié.
    

    
    La directive suivante accorderait l'autorisation d'accès à tout
    utilisateur possédant un téléphone cellulaire et faisant partie du
    département "marketing" :
    

    
    Require ldap-filter &(cell=*)(department=marketing)
    


    
    Alors que la directive Require ldap-attribute se
    contente d'une simple comparaison d'attributs, la directive
    Require ldap-filter effectue une opération de recherche
    dans l'annuaire LDAP en utilisant le filtre de recherche spécifié.
    Si une simple comparaison d'attributs suffit, l'opération de
    comparaison effectuée par ldap-attribute sera plus
    rapide que l'opération de recherche effectuée par
    ldap-filter, en particulier dans le cas d'un annuaire
    LDAP de grande taille.

    Exemples
    

    
      
      
    • 
        Accorde l'autorisation d'accès à tout utilisateur présent dans
	l'annuaire LDAP, en utilisant son UID pour effectuer la
	recherche :

      AuthLDAPURL "ldap://ldap1.example.com:389/ou=People, o=Example?uid?sub?(objectClass=*)"
Require valid-user
      

      
      • 

      
    • 
        L'exemple suivant est similaire au précédent, mais les champs
	dont les valeurs par défaut conviennent sont omis. Notez aussi
	la présence d'un annuaire LDAP redondant :

      AuthLDAPURL "ldap://ldap1.example.com ldap2.example.com/ou=People, o=Example"
Require valid-user
      

      
      • 

      
    • 
        Encore un exemple similaire aux précédents, mais cette fois,
	c'est l'attribut cn qui est utilisé pour la recherche à la place
	de l'UID. Notez que ceci peut poser problème si plusieurs
	utilisateurs de l'annuaire partagent le même cn,
	car une recherche sur le cn doit
	retourner une entrée et une seule. C'est pourquoi cette
	approche n'est pas recommandée : il est préférable de choisir un
	attribut de votre annuaire dont l'unicité soit garantie, comme
	uid.

      AuthLDAPURL "ldap://ldap.example.com/ou=People, o=Example?cn"
Require valid-user
      

      
      • 

      
    • 
        Accorde l'autorisation d'accès à tout utilisateur appartenant au
	groupe Administrateurs. Les utilisateurs doivent s'authentifier
	en utilisant leur UID :

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid
Require ldap-group cn=Administrators, o=Example
      

      
      • 

      
    • 
      Accorde l'accès à tout utilisateur appartenant au groupe dont le
      nom correspond au nom d'hôte du serveur virtuel. Dans cet exemple,
      on utilise une expression pour
      construire le filtre.

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid
Require ldap-group cn=%{SERVER_NAME}, o=Example
      

      
      • 

      
    • 
        Pour l'exemple suivant, on suppose que tout utilisateur de chez
	Example qui dispose d'un bippeur alphanumérique possèdera un
	attribut LDAP qpagePagerID. Seuls ces utilisateurs
	(authentifiés via leur UID) se verront accorder l'autorisation
	d'accès :

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid??(qpagePagerID=*)
Require valid-user
      

      
      • 

      
    • 
        
      L'exemple suivant illustre la puissance des filtres pour
	effectuer des requêtes complexes. Sans les filtres, il aurait
	été nécessaire de créer un nouveau groupe LDAP et de s'assurer
	de la synchronisation des membres du groupe avec les
	utilisateurs possédant un bippeur. Tout devient limpide avec les
	filtres. Nous avons pour but d'accorder l'autorisation d'accès à
	tout utilisateur disposant d'un bippeur ainsi qu'à Joe Manager
	qui ne possède pas de bippeur, mais doit tout de même pouvoir
	accéder à la ressource :
      

      AuthLDAPURL ldap://ldap.example.com/o=Example?uid??(|(qpagePagerID=*)(uid=jmanager))
Require valid-user
      


        
      Ce dernier exemple peut sembler confus au premier abord ; en
	fait, il permet de mieux comprendre à quoi doit ressembler le
	filtre en fonction de l'utilisateur qui se connecte. Si Fred
	User se connecte en tant que fuser, le filtre devra
	ressembler à :
      

        
      (&(|(qpagePagerID=*)(uid=jmanager))(uid=fuser))
      

        
      Un recherche avec le filtre ci-dessus ne retournera un
	résultat positif que si fuser dispose d'un bippeur. Si
	Joe Manager se connecte en tant que jmanager, le filtre
	devra ressembler à :
      

        
      (&(|(qpagePagerID=*)(uid=jmanager))(uid=jmanager))
      

        
      Un recherche avec le filtre ci-dessus retournera un
	résultat positif que jmanager dispose d'un
	bippeur ou non

    Mise à disposition des informations de
connexion

    spécifiés par la directive AuthLDAPURL sont enregistrés dans des
    variables d'environnement préfixées par la chaîne "AUTHENTICATE_".
    

    
    Au cours du processus d'autorisation, les attributs LDAP
    spécifiés par la directive AuthLDAPURL sont enregistrés
    dans des variables d'environnement préfixées par la chaîne

    Si les champs attribut contiennent le nom, le CN et le numéro de
    téléphone d'un utilisateur, un programme CGI pourra accéder à ces
    informations sans devoir effectuer une autre requête LDAP pour
    les extraire de l'annuaire.
    

    
    Ceci a pour effet de simplifier considérablement le code et la
    configuration nécessaire de certaines applications web.

    Utilisation d'Active
Directory
    

    
    Active Directory peut supporter plusieurs domaines à la fois.
    Pour faire la distinction entre les utilisateurs de plusieurs
    domaines, on peut ajouter à l'entrée de l'utilisateur dans
    l'annuaire un identifiant appelé Nom
    Principal d'Utilisateur (User Principle Name ou UPN). Cet UPN se
    compose en général du nom de compte de l'utilisateur, suivi du nom
    du domaine considéré, par exemple untel@nz.example.com.
    

    
    Vous voudrez probablement configurer le module
    mod_authnz_ldap afin de pouvoir authentifier les
    utilisateurs de n'importe quel domaine de la forêt Active Directory.
    Ainsi, untel@nz.example.com et
    untel@au.example.com pourront être authentifiés en une
    seule fois par la même requête.
    

    
    Pour y parvenir, on utilise le concept de Catalogue Global
    d'Active Directory. Ce Catalogue Global est une copie en lecture
    seule des attributs sélectionnés de tous les serveurs de la forêt
    Active Directory. Une requête vers le
    Catalogue Global permet donc d'atteindre tous les domaines en une
    seule fois, sans avoir à se connecter aux différents serveurs, via
    des liaisons dont certaines peuvent être lentes.
    

    
    Lorsqu'il est activé, la Catalogue Global est un serveur
    d'annuaire indépendant accessible sur le port 3268 (3269 pour SSL).
    Pour rechercher un utilisateur, effectuez une recherche sur
    l'attribut userPrincipalName, avec une base de recherche
    vide, comme suit :
    


    AuthLDAPBindDN apache@example.com
AuthLDAPBindPassword password
AuthLDAPURL ldap://10.0.0.1:3268/?userPrincipalName?sub
    


    
    Les utilisateurs devront s'authentifier en entrant leur UPN, de
    la formeuntel@nz.example.com.

    Utilisation de Microsoft
    FrontPage avec mod_authnz_ldap
    

    
    Normalement, FrontPage utilise des fichiers utilisateur/groupe
    spécifiques à FrontPage-web (c'est à dire les modules
    mod_authn_file et
    mod_authz_groupfile) pour effectuer toute
    l'authentification. Malheureusement, il ne suffit pas de modifier
    l'authentification LDAP en ajoutant les directives appropriées, car
    ceci corromprait les formulaires de Permissions dans le
    client FrontPage, qui sont censés modifier les fichiers
    d'autorisation standards au format texte.
    

    
    Lorsqu'un site web FrontPage a été créé, lui adjoindre
    l'authentification LDAP consiste à ajouter les directives suivantes
    à chaque fichier .htaccess qui sera créé dans
    le site web :
    

    AuthLDAPURL       "the url"
AuthGroupFile     "mygroupfile"
Require group     "mygroupfile"
    



    Comment ça marche
    

    
    FrontPage restreint l'accès à un site web en ajoutant la
    directive Require valid-user aux fichiers
    .htaccess. La directive Require valid-user
    permettra l'accès à tout utilisateur valide du point de vue
    LDAP. Cela signifie que tout utilisateur possédant une entrée
    dans l'annuaire LDAP sera considéré comme valide, alors que
    FrontPage ne considère comme valides que les utilisateurs
    enregistrés dans le fichier des utilisateurs local. En remplaçant
    l'autorisation par groupe LDAP par une autorisation par fichier de
    groupe, Apache sera en mesure de consulter le fichier des
    utilisateurs local (géré par FrontPage) - au lieu de l'annuaire LDAP
    - lors du processus d'autorisation des utilisateurs.
    

    
    Une fois les directives ajoutées selon ce qui précède, les
    utilisateurs FrontPage pourront effectuer toutes les opérations de
    gestion à partir du client FrontPage.
    



    Avertissements
    

    
      
      
    • Lors du choix de l'URL LDAP, l'attribut à utiliser pour
      l'authentification doit aussi être valide pour le fichier des
      utilisateurs de mod_authn_file. A cette fin,
      l'UID est idéal.
      • 

      
    • Lorsqu'ils ajoutent des utilisateurs via FrontPage, les
      administrateurs de FrontPage doivent choisir des noms
      d'utilisateurs qui existent déjà dans l'annuaire LDAP (pour des
      raisons évidentes). De même, le mot de passe que l'administrateur
      entre dans le formulaire est ignoré, car pour l'authentification,
      Apache utilise le mot de passe de l'annuaire LDAP, et non le mot
      de passe enregistré dans le fichier des utilisateurs, ce qui peut
      semer la confusion parmi les administrateurs web.
      • 

      
      
    • Pour supporter FrontPage, Apache doit être compilé avec
      mod_auth_basic, mod_authn_file
      et mod_authz_groupfile. Ceci est dû au fait
      qu'Apache doit utiliser le fichier de groupes de
      mod_authz_groupfile pour déterminer le niveau
      d'accès d'un utilisateur au site web FrontPage.
      • 

      
    • Les directives doivent être placées dans les fichiers
      .htaccess. Elles ne fonctionneront pas si vous les
      placez dans une section <Location> ou <Directory>. Ceci est dû au fait que pour savoir
      où se trouve la liste des utilisateurs valides,
      mod_authnz_ldap doit être en mesure d'atteindre
      la directive AuthGroupFile qui se trouve
      dans les fichiers .htaccess de FrontPage. Si les directives
      de mod_authnz_ldap ne sont pas situées dans le
      même fichier .htaccess que les directives FrontPage,
      la configuration ne fonctionnera pas, car
      mod_authnz_ldap ne sera jamais en mesure de
      traiter le fichier .htaccess, et par conséquent ne
      pourra jamais trouver le fichier des utilisateurs géré par
      FrontPage.

    Cette directive permet de spécifier quel attribut LDAP est
    utilisé pour vérifier l'appartenance d'un utilisateur à un
    groupe. On peut spécifier plusieurs attributs en répétant cette
    directive plusieurs fois. Si la directive n'est pas définie,
    mod_authnz_ldap utilise les attributs
    member et uniqueMember.

    Lorsqu'elle est définie à on, cette directive
    indique que c'est le DN de l'utilisateur qui doit être utilisé pour
    vérifier son appartenance à un groupe. Dans le cas contraire, c'est
    le nom de l'utilisateur qui sera utilisé. Par exemple, supposons que
    le client envoie le nom d'utilisateur bjenson, qui
    correspond au DN LDAP cn=Babs Jenson,o=Example. Si la
    directive est à on, mod_authnz_ldap va
    vérifier si cn=Babs Jenson, o=Example est un membre du
    groupe. Dans le cas contraire, mod_authnz_ldap
    vérifiera si bjenson est un membre du groupe.

    Directive AuthLDAPInitialBindAsUser
    

    

    Description:Détermine si le serveur effectue la recherche initiale du
DN en utilisant le nom propre de l'utilisateur pour l'authentification

    Module:mod_authnz_ldap
    

    Compatibilité:Disponible depuis la version 2.3.6
    

    
    
    Par défaut, le serveur convertit le nom d'utilisateur pour
    l'authentification de base en nom distinctif LDAP (DN) soit de
    manière anonyme, soit avec un couple nom/mot de passe dédié. Cette
    directive permet de forcer le serveur à utiliser les véritables nom
    d'utilisateur et mot de passe fournis par l'utilisateur pour
    effectuer la recherche initiale du DN.
    

     
    Si le nom d'utilisateur ne peut pas s'authentifier directement
     et nécessite de légères modifications, voir la directive AuthLDAPInitialBindPattern.
    

     
    Cette directive ne doit être utilisée que si votre serveur LDAP
     n'autorise pas les recherches anonymes, ou si vous ne pouvez pas
     utiliser de nom d'utilisateur dédié via la directive AuthLDAPBindDN.
     
    

     
    Non disponible dans la cas d'une autorisation seule
    
         On ne peut utiliser cette directive que si ce module
	 effectue une authentification, et n'a aucun effet si ce module
	 n'est utilisé que pour les processus d'autorisation.

    Directive AuthLDAPInitialBindPattern

serveur LDAP pour effectuer une recherche de DN

    Compatibilité:Disponible depuis la version 2.3.6
    

    
    
    Si la directive AuthLDAPInitialBindAsUser est
    définie à ON, le nom utilisateur pour l'authentification de
    base sera transformé selon l'expression rationnelle
    regex et l'argument substitution spécifiés.
    

    
    L'expression rationnelle est comparée au nom d'utilisateur pour
    l'authentification de base courant. L'argument
    substitution peut contenir des références arrières, mais
    n'effectue aucune autre interpolation de variable.
    

    
    Cette directive ne doit être utilisée que si votre serveur LDAP
     n'autorise pas les recherches anonymes, ou si vous ne pouvez pas
     utiliser de nom d'utilisateur dédié via la directive AuthLDAPBindDN.

	 effectue une authentification, et n'a aucun effet si ce module
	 n'est utilisé que pour les processus d'autorisation.
     
    
    
    Débogage
    
        Le DN de substitution est enregistré dans la variable
	d'environnement LDAP_BINDASUSER. Si l'expression
	rationnelle ne convient pas, le nom d'utilisateur est utilisé
	tel quel.

    Lorsque cette directive est définie à une valeur X
   non nulle, en combinaison avec l'utilisation de la directive
   Require ldap-group DN-groupe, les données de connexion
   fournies seront utilisées pour vérifier l'appartenance de
   l'utilisateur à l'objet de l'annuaire DN-groupe ou à
   tout sous-groupe du groupe courant en tenant compte de la profondeur
   d'imbrication maximale X spécifiée par la directive.
    
   
    Se référer à la section Require
   ldap-group pour un exemple plus détaillé.
    

   
    Performances dans le cas des groupes imbriqués
    
   
    Lorsque les directives
   AuthLDAPSubGroupAttribute et
   AuthLDAPGroupAttribute se recouvrent (comme
   c'est le cas par défaut et requis par les schémas LDAP courants), la
   recherche de sous-groupes au sein de grands groupes peut être très
   longue. Si vos groupes sont très grands et non imbriqués, définissez
   la directive AuthLDAPMaxSubGroupDepth à 0.

    REMOTE_USER sera définie à la valeur de l'attribut spécifié.
    Assurez-vous que cet attribut soit bien inclus dans la liste d'attributs
    spécifiés dans la définition de AuthLDAPURL ; dans le cas contraire,
    cette directive n'aurait aucun effet. Si elle est présente, cette directive
    l'emporte sur AuthLDAPRemoteUserIsDN. Elle peut
    s'avérer utile par exemple, si vous souhaitez que les utilisateurs se
    connectent à un site web en utilisant leur adresse email, alors qu'une
    application sous-jacente nécessite un nom d'utilisateur comme
    identifiant.

    Lorsque cette directive est définie, et si
    mod_authnz_ldap a authentifié l'utilisateur, les
    recherches LDAP pour définir les autorisations utilisent le nom
    distinctif (DN) trouvé et le mot de passe pour l'authentification de
    base HTTP de l'utilisateur authentifié, au lieu des données
    d'authentification configurées au niveau du serveur.
    

    
    Les vérifications d'autorisation ldap-filter et
    ldap-dn utilisent des recherches.
    

    
    Cette directive n'a d'effet sur les comparaisons effectuées au
    cours des traitements de groupe imbriqués, et lorsque la directive

    Compatibilité:Disponible depuis la version 2.3 d'Apache
    

    Sommaire
    


    
mod_heartmonitor interprète les messages d'état générés
par les serveurs d'origine pour lesquels mod_heartbeat est activé et
fournit ces informations à mod_lbmethod_heartbeat, ce
qui permet d'utiliser la lbmethod "heartbeat" au sein des
directives ProxyPass.

    


    Ce module utilise les services de mod_slotmem_shm,
lorsqu'il est disponible, au lieu d'un simple fichier texte. Aucune
configuration supplémentaire n'est requise pour utiliser
mod_slotmem_shm.
    

    
    
        Pour utiliser mod_heartmonitor,
	mod_status et mod_watchdog
	doivent être soit des modules statiques, soit des modules
	dynamiques, et dans ce dernier cas, ils doivent être chargés
	avant mod_heartmonitor.

    La directive HeartbeatListen permet de
    spécifier l'adresse multicast sur laquelle le serveur va surveiller les
    informations d'état en provenance de serveurs où
    mod_heartbeat est activé. Cette adresse correspond
    en général à la valeur de la directive HeartbeatAddress sur le serveur
    d'origine.
    
    

    
    HeartbeatListen 239.0.0.1:27999

    La directive HeartbeatMaxServers
    spécifie le nombre maximal de serveurs qui pourront envoyer des
    requêtes heartbeat à ce serveur de monitoring. Elle permet ainsi de
    contrôler la quantité de mémoire partagée allouée pour le stockage
    des données heartbeat lorsqu'on utilise

    Module Apache mod_proxy_fcgi
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Module fournissant le support de FastCGI à
mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_fcgi_module
    

    Fichier Source:mod_proxy_fcgi.c
    

    Compatibilité:Disponible depuis la version 2.3 d'Apache
    

    Sommaire
    

    
    Pour fonctionner, ce module nécessite le chargement de
    mod_proxy. Il fournit le support du protocole FastCGI.
    

    
    Ainsi, pour pouvoir traiter le protocole FastCGI,
    mod_proxy et mod_proxy_fcgi
    doivent être chargés dans le serveur.
    

    
    A la différence de mod_fcgid et mod_fastcgi,
    mod_proxy_fcgi n'est pas en mesure de démarrer le
    processus de l'application ; fcgistarter est
    fourni à cet effet sur certaines plateformes. Le framework
    applicatif FastCGI utilisé peut aussi fournir la gestion des
    processus ou des lancements de programmes externes.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large.
    
    
    

    


    top
    

    

    Exemples
    
    
    Pour que ces exemples fonctionnent, vous ne devez pas oublier
    d'activer mod_proxy et
    mod_proxy_fcgi.
    

    
    Instance d'application unique
    ProxyPass "/mon_appli/" "fcgi://localhost:4000/"
    

    

    
    
    mod_proxy_fcgi interdisant par défaut la
    réutilisation des connexions, lorsqu'une requête a été traitée, la
    connexion ne sera pas maintenue ouverte par le processus enfant
    httpd, et ne sera donc pas réutilisée. Cependant, si l'application
    FastCGI supporte les connexions httpd simultanées, vous pouvez opter
    pour la réutilisation des connexions comme dans l'exemple suivant :
    

    
    Instance d'application unique, réutilisation
    des connexions (versions 2.4.11 et supérieures)
    ProxyPass "/myapp/" "fcgi://localhost:4000/" enablereuse=on
    

    

    
    Active la réutilisation des connexions vers un serveur FCGI
    d'arrière-plan tel que PHP-FPM
    
    
    Il faut garder à l'esprit que PHP-FPM (en février 2018) utilise un modèle
    du style prefork ; autrement dit, chacun de ses processus de travail ne peut
    gérer qu'une connexion à la fois.
     Par défaut et lorsqu'il est
    configuré avec enablereuse=on et lorsqu'un MPM à base de
    threads est utilisé (comme worker ou
    event), mod_proxy autorise un jeu de ThreadsPerChild connexions vers le serveur
    d'arrière-plan pour chaque processus httpd, et par conséquent, il faut
    prêter une attention particulière aux situations suivantes :
    
    
      
      
    • Avec une charge en HTTP/1, il est fort probable que le nombre de
      connexions vers le serveur FCGI d'arrière-plan augmente jusqu'à atteindre
      MaxRequestWorkers.
      • 
      
    • Avec une charge en HTTP/2, et vue la manière dont
      mod_http2 est implémenté, il y a des threads de travail
      h2 additionnels qui peuvent forcer la création de connexions
      supplémentaires vers le serveur d'arrière-plan. Le nombre total de
      connexions que contiennent les jeux de connexions peut alors dépasser
      MaxRequestWorkers.
      • 
    
    
    
    Le nombre maximum de processus de travail PHP-FPM doit être défini
    judicieusement car il est possible qu'ils finissent par rester dans l'état
    occupé ("busy") pour ne gérer que des connexions persistantes inactives,
    sans avoir la possibilité d'en établir de nouvelles ; ce qui se traduira
    pour l'utilisateur final par une pile de "HTTP request timeouts".
    
    
    

    
    Dans l'exemple suivant, l'URI de la requête est transmis en tant
    que chemin du système de fichiers pour l'exécution du démon PHP-FPM.
    L'URL de la requête est implicitement ajoutée au second paramètre.
    PHP-FPM est à l'écoute de l'hôte et du port qui
    suivent fcgi://. La conservation/réutilisation des connexions est activée.
    
    
    PHP-FPM
    ProxyPassMatch "^/myapp/.*\.php(/.*)?$" "fcgi://localhost:9000/var/www/" enablereuse=on
    

    

    
    Dans l'exemple suivant, l'URI de la requête est transmis en tant
    que chemin du système de fichiers pour l'exécution du démon PHP-FPM.
    Dans ce cas cependant, PHP-FPM est à l'écoute d'un socket de domaine
    unix (UDS). Cette fonctionnalité est disponible à partir de la
    version 2.4.9. Avec cette syntaxe, si un nom d'hôte et un port sont
    ajoutés après fcgi://, ils seront ignorés.
    
    
    PHP-FPM with UDS
    ProxyPassMatch "^/(.*\.php(/.*)?)$" "unix:/var/run/php5-fpm.sock|fcgi://localhost/var/www/"
    

    

    
    La passerelle à répartition de charge nécessite le chargement du
    module mod_proxy_balancer et d'au moins un module
    fournissant un algorithme de répartition de charge, comme
    mod_lbmethod_byrequests en plus des modules
    déjà cités. mod_lbmethod_byrequests est le module
    par défaut et sera utilisé dans cet exemple de configuration.
    

    
    Passerelle à répartition de charge vers plusieurs
    instances de l'application
    ProxyPass "/myapp/" "balancer://myappcluster/"
<Proxy "balancer://myappcluster/">
    BalancerMember "fcgi://localhost:4000"
    BalancerMember "fcgi://localhost:4001"
</Proxy>
    

    

    
    Vous pouvez aussi forcer le traitement d'une requête en tant que
    requête de mandataire inverse en créant un court-circuiteur de
    gestionnaire approprié. Dans l'exemple ci-dessous, toutes les
    requêtes pour des scripts PHP seront transmises au serveur FastCGI
    spécifié par mandat inverse. Cette fonctionnalité est disponible à
    partir de la version 2.4.10 du serveur HTTP Apache. Pour des raisons
    de performances, il est recommandé de définir un worker (configuration d'un
    mandataire) représentant le même serveur fcgi:// d'arrière-plan.
    Avec cette configuration, il est possible d'effectuer une
    correspondance directe entre l'URI et le chemin du fichier sur le
    serveur, et le chemin local du fichier sera alors transmis au serveur
    d'arrière-plan. Lorsque FastCGI est configuré ainsi, le serveur est
    en mesure de calculer le PATH_INFO le plus approprié.
      
    
	
    Mandataire via un gestionnaire
    <FilesMatch "\.php$">
    # Note : la seule partie variable est /path/to/app.sock
    SetHandler  "proxy:unix:/path/to/app.sock|fcgi://localhost/"
</FilesMatch>
   # Définition d'une configuration de mandataire qui convient.
   # La partie qui est mise en correspondance avec la valeur de
   # SetHandler est la partie qui suit le "pipe". Si vous devez faire
   # une distinction, "localhost" peut être changé en un nom de serveur
   # unique.
   <Proxy "fcgi://localhost/" enablereuse=on max=10>
   </Proxy>

<FilesMatch ...>
    SetHandler  "proxy:fcgi://localhost:9000"
</FilesMatch>

<FilesMatch ...>
    SetHandler  "proxy:balancer://myappcluster/"
</FilesMatch>

    Variables d'environnement
    
    
    En plus des directives de configuration qui contrôlent le
    comportement de mod_proxy, de nombreuses
    variables d'environnement permettent de piloter le
    fournisseur du protocole FCGI :
    
    
    
        
    proxy-fcgi-pathinfo
    
        
    Lorsqu'il est configuré via les directives ProxyPass ou ProxyPassMatch,
	mod_proxy_fcgi ne définit
	pas la variable d'environnement PATH_INFO,
	ce qui permet au serveur FCGI d'arrière-plan de déterminer
	correctement SCRIPT_NAME et Script-URI, et
	de se conformer à la section 3.3 de la RFC 3875. Si au contraire
	vous avez souhaitez que mod_proxy_fcgi génère une
	"estimation la plus exacte possible" de PATH_INFO,
	définissez la variable d'environnement
	proxy-fcgi-pathinfo. Ceci peut servir de
	contournement pour une bogue présente dans certaines
	implémentations de FCGI. Cette variable peut être
	multivaluée afin de pouvoir choisir la valeur la plus appropriée
	(versions 2.4.11 et supérieures) :
	
    
          
    first-dot
    
          
    PATH_INFO est extrait à partir du slash qui suit le
	  premier "." de l'URL.
    
          
    last-dot
    
          
    PATH_INFO est extrait à partir du slash qui suit le
	  dernier "." de l'URL.
    
          
    full
     
          
    PATH_INFO est calculé en supposant que l'URL correspond au
	  chemin du système de fichiers.
    
          
    unescape
    
          
    PATH_INFO correspond à la partie chemin de l'URL avec ses
	  séquences d'échappement décodées.
    
          
    toute autre valeur
    
          
    PATH_INFO correspond à la partie chemin de l'URL.  
              Auparavant, c'était la seule option pour proxy-fcgi-pathinfo.

    Directive ProxyFCGIBackendType
    

    

    Description:Spécifie le type de l'application FastCGI d'arrière-plan
    

    Syntaxe:ProxyFCGIBackendType FPM|GENERIC
    

    Défaut:ProxyFCGIBackendType FPM
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Statut:Extension
    

    Module:mod_proxy_fcgi
    

    Compatibilité:Disponible à partir de la version 2.4.26 du serveur HTTP Apache
    

    

    Cette directive permet de spécifier le type de l'application FastCGI
d'arrière-plan. Certains serveurs FastCGI, comme PHP-FPM, utilisent de manière
historique des variables d'environnement exotiques pour identifier le type du
serveur mandataire utilisé. Définissez cette directive à "GENERIC" si votre
application n'est pas de type PHP-FPM et n'interpréter pas correctement des
variables d'environnement comme SCRIPT_FILENAME ou PATH_TRANSLATED telles
qu'elles sont définies par le serveur.
    


    SCRIPT_FILENAME est un exemple de valeur modifiée par la définition de cette
directive. Historiquement, lorsqu'on utilisait le module
mod_proxy_fcgi, SCRIPT_FILENAME était préfixé par la chaîne
"proxy:fcgi://". C'est cette variable que lisent certaines applications FastCGI
génériques en tant que valeur en entrée pour leur script ; cependant, PHP-FPM
peut supprimer le préfixe, puis garder en mémoire qu'il communique avec Apache.
Avec les versions 2.4.21 à 2.4.25, ce préfixe était automatiquement supprimé par
le serveur, empêchant ainsi PHP-FPM de détecter et interopérer avec Apache dans
certains scénarios.

    Directive ProxyFCGISetEnvIf
    

    

    Description:Permet d'adapter la valeur des variables envoyées aux serveurs
FastCGI
    

    Syntaxe:ProxyFCGISetEnvIf conditional-expression
    [!]environment-variable-name
    [value-expression]
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Statut:Extension
    

    Module:mod_proxy_fcgi
    

    Compatibilité:Disponible à partir de la version 2.4.26 du serveur HTTP Apache.
    

    

    Juste avant la transmission d'une requête au serveur FastCGI configuré, le
coeur du programme du serveur web définit un certain nombre de variables
d'environnement en fonction de certains détails de la requête considérée. Les
programmes FastCGI utilisent souvent ces variables comme données en entrée afin
de déterminer quels scripts sous-jacents ils vont exécuter, ou quelles données
en sortie doivent être produites.
    

    Voici quelques exemples de variables d'environnement importantes :
    

      
  
    • SCRIPT_NAME
      • 
  
    • SCRIPT_FILENAME
      • 
  
    • REQUEST_URI
      • 
  
    • PATH_INFO
      • 
  
    • PATH_TRANSLATED
      • 

    


    Cette directive permet de passer outre les variables d'environnement
ci-dessus, entre autres. Elle est évaluée après la définition de la valeur
initiale de ces variables ; elle peuvent donc être utilisées comme entrées dans
les expressions définissants les conditions et les valeurs.
    

    Syntaxe des paramètres :
    

    

    conditional-expression
     

    Définit une condition en fonction de laquelle la
variable d'environnement qui suit sera modifiée ou non. Pour la syntaxe de cette
expression, reportez-vous aux exemples qui suivent ou à la spécification
détaillée dans le document ap_expr.
   
    

    environment-variable-name
     

    Spécifie le nom de la variable d'environnement à modifier, par exemple
PATH_INFO. Si elle est précédée d'un point d'exclamation, la définition de la
variable sera annulée.
    

    value-expression
    

    Spécifie la nouvelle valeur de la variable "environment-variable-name". On
peut inclure des
références arrières, comme "$1", issues de captures en provenance de
l'expression rationnelle conditional-expression. Si cette valeur est
omise, la variable est définie (ou sa valeur est écrasée) par une chaîne vide
— voir cependant la note ci-après.
    

    
  

    # Une modification basique, inconditionnelle
ProxyFCGISetEnvIf "true" PATH_INFO "/example"

# Utilisation d'une variable d'environnement pour spécifier la nouvelle valeur
ProxyFCGISetEnvIf "true" PATH_INFO "%{reqenv:SCRIPT_NAME}"

    
# Utilisation de captures dans la condition et de références arrières dans la
# nouvelle valeur
ProxyFCGISetEnvIf "reqenv('PATH_TRANSLATED') =~ m#(/.*prefix)(\d+)(.*)#" PATH_TRANSLATED "$1$3"
    

    


    Note : Annulation définition ou valeur vide
    
  La ligne suivante annule la définition de la variable VARIABLE,
  ce qui l'empêche d'être envoyée au serveur FastCGI :

    
    ProxyFCGISetEnvIf true !VARIABLE
    


  La ligne suivante, quant à elle, efface la valeur de la variable
  VARIABLE en lui affectant la chaîne vide ; cette variable
  VARIABLE sera alors tout de même envoyée au serveur FastCGI :

    
    ProxyFCGISetEnvIf true VARIABLE
    


  La spécification CGI/1.1 ne fait pas de
  distinction entre une variable contenant une chaîne vide et une variable qui
  n'existe pas. De nombreuses implémentations CGI et FastCGI font cependant
  cette distinction (ou permettent aux scripts de la faire). Le choix de celle
  que vous allez utiliser dépend de votre implémentation et de la raison qui
  vous pousse à modifier cette variable.

    Apache Module mod_buffer

    Description:Support for request buffering
    

    Status:Extension
    

    Module Identifier:buffer_module
    

    Source File:mod_buffer.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    

    
    This module provides the ability to buffer the input and output
    filter stacks.
    

    
    Under certain circumstances, content generators might create
    content in small chunks. In order to promote memory reuse, in
    memory chunks are always 8k in size, regardless of the size of the
    chunk itself. When many small chunks are generated by a request,
    this can create a large memory footprint while the request is
    being processed, and an unnecessarily large amount of data on the
    wire. The addition of a buffer collapses the response into the
    fewest chunks possible.
    

    
    When httpd is used in front of an expensive content generator,
    buffering the response may allow the backend to complete
    processing and release resources sooner, depending on how the
    backend is designed.
    

    
    The buffer filter may be added to either the input or the
    output filter stacks, as appropriate, using the
    SetInputFilter,
    SetOutputFilter,
    AddOutputFilter or
    AddOutputFilterByType directives.
    

      
    Using buffer with mod_include
    AddOutputFilterByType INCLUDES;BUFFER text/html
    

    

    
    The buffer filters read the request/response into
        RAM and then repack the request/response into the fewest memory
        buckets possible, at the cost of CPU time. When the request/response
        is already efficiently packed, buffering the request/response could
        cause the request/response to be slower than not using a buffer at
        all. These filters should be used with care, and only where
        necessary.

    buffered before being read from or written to each request.
    The default is 128 kilobytes.

    概要
    

    
    本モジュールには mod_proxy が必要です。
    HTTP, FTP と AJP13
    プロトコルのロードバランス機能を持っています。
    

    
    ですから、 ロードバランスを有効にする場合 mod_proxy
    と mod_proxy_balancer がサーバに組み込まれて
    いなければいけません。
    

    
    警告
    
      
    安全なサーバにするまでプロクシ機能は有効にしないでください。
      オープンプロキシサーバはあなた自身のネットワークにとっても、
      インターネット全体にとっても危険です。

    ロードバランサのスケジューラのアルゴリズム
    
    
    
    現時点では 2 種類のロードバランサスケジューラアルゴリズムから選べます。
    リクエスト回数によるもの (訳注: Request Counting)
    と、トラフィック量によるもの (訳注: Weighted Traffic Counting)
    があります。バランサの設定 lbmethod 値で、どちらを使うか指定します。
    詳細は Proxy ディレクティブを
    参照してください。
    


    top
    

    

    Request Counting アルゴリズム
    
    
    
    lbmethod=byrequests で有効になります。
    このスケジューラの背景にある考え方は、様々なワーカーがそれぞれ、
    設定されている分担リクエスト数をきちんと受け取れるように、
    リクエストを扱うという考え方です。次のように動作します:
    

    
    lbfactor は、どの程度ワーカーに仕事を振るか
    つまりワーカーのクオータを指します。この値は "分担" 
    量を表す正規化された値です。
    

    
    lbstatus は、ワーカーのクオータを満たすために
    どのぐらい急ぎで働かなければならないかを指します。
    

    
    ワーカーはロードバランサのメンバで、通常は、
    サポートされるプロトコルのうちの一つを提供しているリモートホストです。
    
    

    
    まず個々のワーカーにワーカークオータを割り振り、どのワーカーが最も急ぎで
    働かなければならないか (lbstatus が最大のもの) を調べます。
    次に仕事をするようにこのワーカーを選択し、選択したワーカーの lbstatus 
    を全体に割り振ったぶんだけ差し引きます。ですから、lbstatus の総量は
    結果的に変化しません(*)し、リクエストは期待通りに分散されます。
    

    
    あるワーカーが無効になっても、他のものは正常にスケジュールされ続けます。
    
    

    
    for each worker in workers
    worker lbstatus += worker lbfactor
    total factor    += worker lbfactor
    if worker lbstatus > candidate lbstatus
        candidate = worker

candidate lbstatus -= total factor
    

    
    バランサを次のように設定した場合:
    
    
    
    worker
        a
        b
        c
        d
    

    lbfactor
        25
        25
        25
        25
    

    lbstatus
        0
        0
        0
        0
    

    

    
    そして b が無効になった場合、次のようなスケジュールが
    行われます。
    

    
    worker
        a
        b
        c
        d
    

    lbstatus
        -50
        0
        25
        25
    

    lbstatus
        -25
        0
        -25
        50
    

    lbstatus
        0
        0
        0
        0
    

    (repeat)
    

    

    
    つまりこのようにスケジュールされます: a c
    d a c d a
    c d ... 次の点に注意してください:
    

    
    worker
        a
        b
        c
        d
    

    lbfactor
        25
        25
        25
        25
    

    

    
    この挙動は、次の設定と全く同じになります:
    

    
    worker
        a
        b
        c
        d
    

    lbfactor
        1
        1
        1
        1
    

    

    
    This is because all values of lbfactor are normalized
    with respect to the others. For:
    
    
    lbfactor は全て正規化されたもので、
    他との相対値だからです。次の設定では:
    

    
    worker
        a
        b
        c
    

    lbfactor
        1
        4
        1
    

    

    
    ワーカー b は、平均して、a と c
    の 4 倍の数のリクエストを受け持つことになります。
    

    
    次のような非対称な設定では、こうなると予想されるでしょう:
    

    
    worker
        a
        b
    

    lbfactor
        70
        30
    

     
    

    lbstatus
        -30
        30
    

    lbstatus
        40
        -40
    

    lbstatus
        10
        -10
    

    lbstatus
        -20
        20
    

    lbstatus
        -50
        50
    

    lbstatus
        20
        -20
    

    lbstatus
        -10
        10
    

    lbstatus
        -40
        40
    

    lbstatus
        30
        -30
    

    lbstatus
        0
        0
    

    (repeat)
    

    

    
    スケジュールは 10 スケジュール後に繰り返され、a 7 回と
    b 3 回でまばらに選ばれます。
    

    top
    

    

    Weighted Traffic Counting アルゴリズム
    
    
    
    lbmethod=bytraffic で有効になります。
    このスケジューラの背景にある考え方は、Request Counting 
    と非常に似ていますが、次の違いがあります:
    

    
    lbfactor は どれだけのバイト数のトラフィック量を、
    このワーカーに処理してもらいたいか を表します。
    この値も同様に正規化された値で、ワーカー全体のうちでの "分担"
    量を表現しています。リクエスト数を単純に数える代わりに、
    どれだけの転送量を処理したかを数えます。
    

    
    次のようにバランサを設定した場合:
    
    
    
    worker
        a
        b
        c
    

    lbfactor
        1
        2
        1
    

    

    
    b には a や c の 2 倍
    処理してほしいということになります。
    b は 2 倍の I/O を処理するという意味になり、
    2 倍のリクエスト数を処理するということにはなりません。
    ですからリクエストとレスポンスのサイズが、
    重み付けと振り分けのアルゴリズムに効いています。
    


    top
    

    

    バランサマネージャのサポートを有効にする
    
    
    
    このモジュールは mod_status のサービスを
    必要とします。
    バランサマネージャを使うと、バランサのメンバーの動的な更新が
    できます。バランサマネージャを使って、バランス係数 (lbfactor)
    を変更したり、メンバーを変更したり、特定のメンバーを
    オフラインモードにしたりできます。
    

    
    ですから、ロードバランサ管理機能を使いたければ、
    mod_status と mod_proxy_balancer
    をサーバに組み込まなければなりません。
    

    
    foo.com ドメインのブラウザからロードバランサ管理機能を
    使えるようにするには、次のようなコードを httpd.conf
    に追加します。
    

    
    <Location /balancer-manager>
    
    SetHandler balancer-manager
    

    
    Order Deny,Allow
    
    Deny from all
    
    Allow from .foo.com
    
    </Location>

    

    
    こうすると、http://your.server.name/balancer-manager
    のページ経由で、ウェブブラウザからロードバランサマネージャに
    アクセスできるようになります。

    Sommaire
    

    
    Le module mod_dbd gère les connexions
    à une base de données SQL via APR. Il permet
    aux modules qui requièrent des fonctions liées aux bases de données
    SQL de se connecter à une base de données à la demande, et s'efforce
    de conférer aux bases de données une efficacité et une
    évolutivité optimales pour les MPMs threadés ou non threadés. Pour
    plus de détails, voir le site web APR,
    ainsi que cette vue d'ensemble de l'environnement de
    développement d'Apache DBD par son développeur initial.

    Regroupement des connexions
    
    
    Ce module gère de manière optimisée en fonction de la plate-forme
    les connexions aux bases de données. Sur les plates-formes non
    threadées, il maintient une connexion persistente à la manière d'un
    LAMP classique (Linux, Apache, Mysql, Perl/PHP/Python). Sur les
    plates-formes threadées, il maintient un groupe de
    connexions à la fois plus évolutif et plus efficace, comme
    décrit dans cet
    article d'ApacheTutor. Notez que mod_dbd
    remplace les modules présentés dans cet article.

    Connexion
    

    
    Pour vous connecter à votre base de données, vous devez spécifier un
    pilote et des paramètres de connexion qui diffèrent selon le moteur de base
    de données. Par exemple, pour vous connecter à mysql, spécifiez ce qui suit
    :
    


    DBDriver mysql
DBDParams host=localhost,dbname=pony,user=shetland,pass=appaloosa
    


    
    Vous pourrez alors utiliser cette connexion dans de nombreux autres
    modules comme mod_rewrite, mod_authn_dbd
    et mod_lua. Vous trouverez des exemples d'utilisation dans
    la documentation de ces modules.
    

    
    Voir la syntaxe de la directive DBDParams pour les
    informations à fournir dans la chaîne de connexion en fonction des
    différents pilotes de base de données supportés.

    API DBD d'Apache
    
    
    mod_dbd exporte cinq fonctions que d'autres
    modules pourront utiliser. L'API se présente comme suit :
    

    
    typedef struct {
    apr_dbd_t *handle;
    apr_dbd_driver_t *driver;
    apr_hash_t *prepared;
} ap_dbd_t;

/* Fonctions exportées pour accéder à la base de données */

/* ouvre une connexion qui DOIT avoir été explicitement fermée.
 * Renvoie NULL en cas d'erreur
 */
AP_DECLARE(ap_dbd_t*) ap_dbd_open(apr_pool_t*, server_rec*);

/* ferme une connexion ouverte avec ap_dbd_open */
AP_DECLARE(void) ap_dbd_close(server_rec*, ap_dbd_t*);

/* acquiert une connexion qui aura la durée de vie de la requête et qui
 * NE DOIT PAS avoir été explicitement fermée. Renvoie NULL en cas
 * d'erreur. C'est la fonction recommandée pour la plupart des
 * applications.
 */
AP_DECLARE(ap_dbd_t*) ap_dbd_acquire(request_rec*);

/* acquiert une connexion qui aura la durée de vie d'une connexion et
 * qui NE DOIT PAS avoir été explicitement fermée. Renvoie NULL en cas
 * d'erreur.
 */
AP_DECLARE(ap_dbd_t*) ap_dbd_cacquire(conn_rec*);

/* Prépare une requête qu'un module client pourra utiliser */
AP_DECLARE(void) ap_dbd_prepare(server_rec*, const char*, const char*);

/* Exporte aussi ces fonctions à titre optionnel mour les modules qui
 * péfèreraient les utiliser */
APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_open, (apr_pool_t*, server_rec*));
APR_DECLARE_OPTIONAL_FN(void, ap_dbd_close, (server_rec*, ap_dbd_t*));
APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_acquire, (request_rec*));
APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_cacquire, (conn_rec*));
APR_DECLARE_OPTIONAL_FN(void, ap_dbd_prepare, (server_rec*, const char*, const char*));
    


    top
    

    

    Requêtes SQL préparées
    
    
    mod_dbd supporte les requêtes SQL préparées à
    destination des modules qui pourraient les utiliser. Chaque requête
    préparée doit posséder un nom (étiquette), et est stockée dans un
    condensé (hash) : les condensés sont du type
    apr_dbd_prepared_t et s'utilisent dans toute requête
    SQL ou commande select préparée par apr_dbd.
    

    
    Il est du ressort des modules utilisateurs de dbd d'utiliser les
    requêtes préparées et de préciser quelles requêtes doivent être
    spécifiées dans httpd.conf, ou de fournir leurs propres directives
    et d'utiliser ap_dbd_prepare.
    

    
    Avertissement
    
	Lorsqu'on utilise des requêtes préparées avec des bases de
	données MySQL, il est préférable de définir
	reconnect à 0 dans la chaîne de connexion, afin
	d'éviter des erreurs provoquées par un client MySQL qui se
	reconnecterait sans réinitialiser correctement les requêtes
	préparées. Si reconnect est défini à 1, toute
	connexion défectueuse sera sensée être réparée, mais comme
	mod_dbd n'en est pas informé, les requêtes préparées seront
	invalidées.

    AVERTISSEMENT DE SECURITE
    

    
    Toute application web impliquant une base de données doit se
    protéger elle-même contre les attaques de type injection SQL. Dans
    la plupart des cas Apache DBD est sûr, car les applications
    utilisent des requêtes préparées, et les entrées non sures ne seront
    utilisées qu'à titre de données. Bien entendu, si vous l'utilisez
    via un module tiers, vous devez être au fait des précautions à
    prendre.
    
    
    Cependant, le pilote FreeTDS est non
    sûr de par sa nature-même. Comme la bibliothèque
    sous-jacente ne supporte pas les requêtes préparées, le pilote en
    effectue une émulation, et les entrées non sûres sont fusionnées
    avec la requête SQL.
    
    
    Il peut être sécurisé en décontaminant toutes les
    entrées : un processus inspiré de la recherche de contaminations
    (taint mode) de
    Perl. Chaque entrée est comparée à une expression rationnelle, et
    seules les entrées qui correspondent sont utilisées, en accord avec
    le langage Perl :
    
    
      $untrusted =~ /([a-z]+)/;
  $trusted = $1;
    
    
    Pour utiliser ceci, les expressions rationnelles de
    décontamination doivent être incluses dans les requêtes préparées.
    L'expression rationnelle doit se situer immédiatement après le
    caractère % dans la requête préparée, et doit être entourée
    d'accolades {}. Par exemple, si votre application attend une entrée
    alphanumérique, vous pouvez utiliser :
    
    
    
       "SELECT foo FROM bar WHERE input = %s"
    
    
    
    avec d'autres pilotes, et ne risquer au pire qu'une requête
    échouée. Mais avec FreeTDS, vous devez utiliser :
    
    
    
       "SELECT foo FROM bar WHERE input = %{([A-Za-z0-9]+)}s"
    
    
    
    tout ce qui ne correspond pas à l'expression rationnelle est
    alors rejeté, et la requête est maintenant sûre.
    
    
    Alternativement, vous pouvez utiliser le pilote ODBC tiers, qui
    offre la sécurité des requêtes préparées authentiques.

    Cette directive permet de spécifier des paramètres selon les
    besoins du pilote concerné. En général, les paramètres à passer
    concernent tout ce qui n'a pas de valeur par défaut comme le nom
    d'utilisateur, le mot de passe, le nom de la base de données, le nom
    d'hôte et le numéro de port de la connexion.
    
    
    Les paramètres de la chaîne de connexion en fonction des
    différents pilotes comprennent :
    
    
    
    
    FreeTDS (pour MSSQL et SyBase)

    La chaîne de connexion est scindée avec comme séparateur le
    caractère ':', et partie1:partie2 est utilisé dans
    sqlite_open(partie1, atoi(partie2), NULL)

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_dbd
    

    
    
    Si cette directive est définie à Off, les connexions persistentes
    et les connexions groupées sont désactivées. À la demande d'un
    client, une nouvelle connexion à la base de données est ouverte, et
    fermée immédiatement à l'issue du traitement. Cette configuration ne
    doit être utilisée qu'à des fins de débogage, ou sur des serveurs à
    charge faible.
    

    
    Par défaut, les groupes de connexions persistentes sont activés
    (ou une seule connexion persistente du style LAMP pour les serveurs
    non threadés), et c'est la configuration qui devrait être utilisée
    dans la plupart des cas sur un serveur en production.
    

    
    Avant la version 2.2.2, cette directive n'acceptait que les
    valeurs 0 et 1 au lieu de Off
    et On, respectivement.

    Statut:Extension
    

    Module:mod_dbd
    

    
    
    Pour les modules tels que les modules d'authentification, qui
    utilisent de manière répétée la même requête SQL, on peut optimiser
    les performances en préparant la requête une fois pour toutes au
    démarrage, plutôt qu'à chaque utilisation. Cette directive permet de
    préparer une requête SQL et de lui assigner une étiquette.

    Statut:Extension
    

    Module:mod_dbd
    

    
    
    Cette directive permet de spécifier un pilote apr_dbd par son
    nom. Le pilote doit être installé sur votre système (sur la plupart
    des systèmes, il s'agit d'un objet partagé ou d'une dll). Par
    exemple, DBDriver mysql va sélectionner le pilote MySQL
    dans la bibliothèque apr_dbd_mysql.so.

    Module Apache mod_proxy_scgi
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Module fournissant le support de la passerelle SCGI à
mod_proxy
    

    Statut:Extension
    

    Identificateur de Module:proxy_scgi_module
    

    Fichier Source:mod_proxy_scgi.c
    

    Compatibilité:Disponible depuis la version 2.2.14 d'Apache
    

    Sommaire
    

    
    Pour pouvoir fonctionner, ce module requiert le
    chargement de mod_proxy. Il fournit le support du
    protocole SCGI, version
    1.
    

    
    Ainsi, pour être en mesure de traiter le protocole SCGI,
    mod_proxy et mod_proxy_scgi
    doivent être chargés dans le serveur.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large.
    
    
    

    


    top
    

    

    Exemples
    
    
    Rappelez-vous, pour que les exemples suivants puissent
    fonctionner, vous devez activer mod_proxy et
    mod_proxy_scgi.
    

    
    Passerelle simple
    ProxyPass "/scgi-bin/" "scgi://localhost:4000/"
    

    

    
    La passerelle à répartition de charge nécessite le chargement du
    module mod_proxy_balancer et d'au moins un module
    fournissant un algorithme de répartition de charge, comme
    mod_lbmethod_byrequests en plus des modules
    déjà cités. mod_lbmethod_byrequests est le module
    par défaut et sera utilisé dans cet exemple de configuration.
    

    
    Passerelle à répartition de charge
    ProxyPass "/scgi-bin/" "balancer://somecluster/"
<Proxy "balancer://somecluster">
    BalancerMember "scgi://localhost:4000"
    BalancerMember "scgi://localhost:4001"
</Proxy>
    

    

    top
    

    

    Variables d'environnement
    
    
    En plus des directives de configuration qui permettent de
    contrôler le comportement de mod_proxy, une
    variable d'environnement peut aussi
    contrôler le fournisseur de protocole SCGI :
    
    
    
        
    proxy-scgi-pathinfo
    
        
    Par défaut, mod_proxy_scgi ne créera ni
	exportera jamais la variable d'environnement
	PATH_INFO. Ceci permet au serveur SCGI d'arrière-plan
	de déterminer correctement SCRIPT_NAME et
	Script-URI, et de rester en conformité avec la section
	3.3 de la RFC 3875. Si au contraire vous souhaitez que
	mod_proxy_scgi génère une estimation la plus
	précise possible de PATH_INFO, définissez cette
	variable d'environnement. La variable doit être définie avant
	que la directive SetEnv ne soit effective. Il est possible
	d'utiliser à la	place la directive SetEnvIf : SetEnvIf Request_URI . proxy-scgi-pathinfo

    Directive ProxySCGIInternalRedirect
    

    

    Description:Active ou désactive les réponses de redirection interne en
provenance du serveur cible.
    

    Syntaxe:ProxySCGIInternalRedirect On|Off|Headername
    

    Défaut:ProxySCGIInternalRedirect On
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy_scgi
    

    Compatibilité:Le paramètre Headername est disponible depuis
la version 2.4.13 du serveur HTTP Apache.
    

    
    
    La directive ProxySCGIInternalRedirect
    permet au serveur cible de rediriger en interne la passerelle vers
    une URL différente. Cette fonctionnalité trouve son origine dans
    mod_cgi qui redirige la réponse en interne si
    l'état de la réponse est OK (200), et si
    la réponse contient un en-tête Location
    (ou un autre en-tête défini) dont la valeur
    débute par un slash (/). Cette valeur est interprétée
    comme une nouvelle URL locale vers laquelle Apache httpd effectue sa
    redirection.
    

    
    De ce point de vue, mod_proxy_scgi fait la même
    chose que mod_cgi, mais vous pouvez en plus
    désactiver la fonctionnalité ou spécifier
    l'utilisation d'un en-tête autre que Location.
    

    
    Exemple
        ProxySCGIInternalRedirect Off
# Django et certains autres frameworks qualifient pleinement les "URLs
# locales" définies par l'application ; il faut donc utiliser un autre
# en-tête.
<Location /django-app/>
    ProxySCGIInternalRedirect X-Location
</Location>
    

    


    

    top
    

    Directive ProxySCGISendfile
    

    

    Description:Active l'évaluation du pseudo en-tête de réponse
X-Sendfile
    

    Syntaxe:ProxySCGISendfile On|Off|nom-en-tête
    

    Défaut:ProxySCGISendfile Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_proxy_scgi
    

    
    
    La directive ProxySCGISendfile permet au
    serveur cible SCGI de faire servir les fichiers directement par la
    passerelle. Ceci s'avère bénéfique en
    matière de performances —
    httpd peut alors utiliser sendfile ou d'autres
    optimisations, ce qui n'est pas possible si les fichiers passent par
    la socket du serveur cible. En outre, les fichiers ne sont transmis
    qu'une seule fois.
    
    
    L'argument de la directive
    ProxySCGISendfile détermine le comportement
    de la passerelle :
    
    
    
    
    Off
    
    
    Aucun traitement particulier n'est effectué.
    

    
    On
    
    
    La passerelle recherche un en-tête dans la réponse du serveur
    cible nommé X-Sendfile, et interprète sa valeur comme
    le nom du fichier à servir. L'en-tête est ensuite supprimé de la
    réponse finale. Cet argument produit le même effet que
    ProxySCGISendfile X-Sendfile.
    

    
    toute autre valeur
    
    
    Identique à On, mais au lieu de rechercher le nom
    d'en-tête codé en dur X-Sendfile, c'est la
    valeur de l'argument qui constitue le nom de l'en-tête
    à rechercher.
    
    
    

    
    Exemple
        # Utilise le nom d'en-tête par défaut (X-Sendfile)
    ProxySCGISendfile On

    # Utilise un nom d'en-tête différent
    ProxySCGISendfile X-Send-Static

    Summary
    

    
    Warning
    
      
    Do not enable proxying with ProxyRequests until you have secured your server. Open proxy servers are dangerous both to your
      network and to the Internet at large.
    
    
    

    
    mod_proxy and related modules implement a
    proxy/gateway for Apache HTTP Server, supporting a number of popular
    protocols as well as several different load balancing algorithms.
    Third-party modules can add support for additional protocols and
    load balancing algorithms.
    

    
    A set of modules must be loaded into the server to provide the
    necessary features.  These modules can be included statically at
    build time or dynamically via the
    LoadModule directive).
    The set must include:
    

    

    
    In addition, extended features are provided by other modules.
    Caching is provided by mod_cache and related
    modules.  The ability to contact remote servers using the SSL/TLS
    protocol is provided by the SSLProxy* directives of
    mod_ssl.  These additional modules will need
    to be loaded and configured to take advantage of these features.

    Forward Proxies and Reverse
       Proxies/Gateways
    
      
    Apache HTTP Server can be configured in both a forward and
      reverse proxy (also known as gateway) mode.
    

      
    An ordinary forward proxy is an intermediate
      server that sits between the client and the origin
      server.  In order to get content from the origin server,
      the client sends a request to the proxy naming the origin server
      as the target. The proxy then requests the content from the
      origin server and returns it to the client.  The client must be
      specially configured to use the forward proxy to access other
      sites.
    

      
    A typical usage of a forward proxy is to provide Internet
      access to internal clients that are otherwise restricted by a
      firewall.  The forward proxy can also use caching (as provided
      by mod_cache) to reduce network usage.
    

      
    The forward proxy is activated using the ProxyRequests directive.  Because
      forward proxies allow clients to access arbitrary sites through
      your server and to hide their true origin, it is essential that
      you secure your server so that only
      authorized clients can access the proxy before activating a
      forward proxy.
    

      
    A reverse proxy (or gateway), by
      contrast, appears to the client just like an ordinary web
      server.  No special configuration on the client is necessary.
      The client makes ordinary requests for content in the namespace
      of the reverse proxy.  The reverse proxy then decides where to
      send those requests and returns the content as if it were itself
      the origin.
    

      
    A typical usage of a reverse proxy is to provide Internet
      users access to a server that is behind a firewall.  Reverse
      proxies can also be used to balance load among several back-end
      servers or to provide caching for a slower back-end server.
      In addition, reverse proxies can be used simply to bring
      several servers into the same URL space.
    

      
    A reverse proxy is activated using the ProxyPass directive or the
      [P] flag to the RewriteRule directive.  It is
      not necessary to turn ProxyRequests on in order to
      configure a reverse proxy.

    Basic Examples
    

    
    The examples below are only a very basic idea to help you
    get started.  Please read the documentation on the individual
    directives.
    

    
    In addition, if you wish to have caching enabled, consult
    the documentation from mod_cache.
    

    
    Reverse Proxy
    ProxyPass "/foo" "http://foo.example.com/bar"
ProxyPassReverse "/foo" "http://foo.example.com/bar"
    

    

    
    Forward Proxy
    ProxyRequests On
ProxyVia On

<Proxy "*">
  Require host internal.example.com
</Proxy>
    

    
    
    top
    

    

    Access via Handler
    

      
    You can also force a request to be handled as a reverse-proxy
        request, by creating a suitable Handler pass-through. The example
        configuration below will pass all requests for PHP scripts to the
        specified FastCGI server using reverse proxy:
      
    

      
    Reverse Proxy PHP scripts
    <FilesMatch "\.php$">
    # Unix sockets require 2.4.7 or later
    SetHandler  "proxy:unix:/path/to/app.sock|fcgi://localhost/"
</FilesMatch>
    

    

      
    This feature is available in Apache HTTP Server 2.4.10 and later.
    

    
    top
    

    

    Workers
    
      
    The proxy manages the configuration of origin servers and their
      communication parameters in objects called workers.
      There are two built-in workers: the default forward proxy worker and the
      default reverse proxy worker. Additional workers can be configured
      explicitly.
    

      
    The two default workers have a fixed configuration
      and will be used if no other worker matches the request.
      They do not use HTTP Keep-Alive or connection reuse.
      The TCP connections to the origin server will instead be
      opened and closed for each request.
    

      
    Explicitly configured workers are identified by their URL.
      They are usually created and configured using
      ProxyPass or
      ProxyPassMatch when used
      for a reverse proxy:
    

      
    ProxyPass "/example" "http://backend.example.com" connectiontimeout=5 timeout=30
    


      
    This will create a worker associated with the origin server URL
      http://backend.example.com that will use the given timeout
      values. When used in a forward proxy, workers are usually defined
      via the ProxySet directive:
    

      
    ProxySet "http://backend.example.com" connectiontimeout=5 timeout=30
    


      
    or alternatively using Proxy
      and ProxySet:
    

      
    <Proxy "http://backend.example.com">
  ProxySet connectiontimeout=5 timeout=30
</Proxy>
    


      
    Using explicitly configured workers in the forward mode is
      not very common, because forward proxies usually communicate with many
      different origin servers. Creating explicit workers for some of the
      origin servers can still be useful if they are used very often.
      Explicitly configured workers have no concept of forward or reverse
      proxying by themselves. They encapsulate a common concept of
      communication with origin servers. A worker created by
      ProxyPass for use in a
      reverse proxy will also be used for forward proxy requests whenever
      the URL to the origin server matches the worker URL, and vice versa.
    

      
    The URL identifying a direct worker is the URL of its
      origin server including any path components given:
    

     
    ProxyPass "/examples" "http://backend.example.com/examples"
ProxyPass "/docs" "http://backend.example.com/docs"
    


      
    This example defines two different workers, each using a separate
      connection pool and configuration.
    

      
    Worker Sharing
    
        
    Worker sharing happens if the worker URLs overlap, which occurs when
        the URL of some worker is a leading substring of the URL of another
        worker defined later in the configuration file. In the following example
    

        
    ProxyPass "/apps" "http://backend.example.com/" timeout=60
ProxyPass "/examples" "http://backend.example.com/examples" timeout=10
    


        
    the second worker isn't actually created. Instead the first
        worker is used. The benefit is, that there is only one connection pool,
        so connections are more often reused. Note that all configuration attributes
        given explicitly for the later worker will be ignored. This will be logged
        as a warning. In the above example, the resulting timeout value
        for the URL /examples will be 60 instead
        of 10!
    

        
    If you want to avoid worker sharing, sort your worker definitions
        by URL length, starting with the longest worker URLs. If you want to maximize
        worker sharing, use the reverse sort order. See also the related warning about
        ordering ProxyPass directives.
    

      
     

      
    Explicitly configured workers come in two flavors:
      direct workers and (load) balancer workers.
      They support many important configuration attributes which are
      described below in the ProxyPass
      directive. The same attributes can also be set using
      ProxySet.
    

      
    The set of options available for a direct worker
      depends on the protocol which is specified in the origin server URL.
      Available protocols include ajp, fcgi,
      ftp, http and scgi.
    

      
    Balancer workers are virtual workers that use direct workers known
      as their members to actually handle the requests. Each balancer can
      have multiple members. When it handles a request, it chooses a member
      based on the configured load balancing algorithm.
    

      
    A balancer worker is created if its worker URL uses
      balancer as the protocol scheme.
      The balancer URL uniquely identifies the balancer worker.
      Members are added to a balancer using
      BalancerMember.
    

      
    DNS resolution for origin domains
    
      
    DNS resolution happens when the socket to
        the origin domain is created for the first time.
        When connection reuse is enabled, each backend domain is resolved 
        only once per child process, and cached for all further connections 
        until the child is recycled. This information should to be considered 
        while planning DNS maintenance tasks involving backend domains. 
        Please also check ProxyPass
        parameters for more details about connection reuse.

    Controlling Access to Your Proxy
    
      
    You can control who can access your proxy via the <Proxy> control block as in
      the following example:
    

      
    <Proxy "*">
  Require ip 192.168.0
</Proxy>
    


      
    For more information on access control directives, see
      mod_authz_host.
    

      
    Strictly limiting access is essential if you are using a
      forward proxy (using the ProxyRequests directive).
      Otherwise, your server can be used by any client to access
      arbitrary hosts while hiding his or her true identity.  This is
      dangerous both for your network and for the Internet at large.
      When using a reverse proxy (using the ProxyPass directive with
      ProxyRequests Off), access control is less
      critical because clients can only contact the hosts that you
      have specifically configured.
    

      
    See Also the Proxy-Chain-Auth environment variable.
    

    
    top
    

    

    Slow Startup
    
      
    If you're using the ProxyBlock directive, hostnames' IP addresses are looked up
      and cached during startup for later match test. This may take a few
      seconds (or more) depending on the speed with which the hostname lookups
      occur.
    
    
    top
    

    

    Intranet Proxy
    
      
    An Apache httpd proxy server situated in an intranet needs to forward
      external requests through the company's firewall (for this, configure
      the ProxyRemote directive
      to forward the respective scheme to the firewall proxy).
      However, when it has to
      access resources within the intranet, it can bypass the firewall when
      accessing hosts. The NoProxy
      directive is useful for specifying which hosts belong to the intranet and
      should be accessed directly.
    

      
    Users within an intranet tend to omit the local domain name from their
      WWW requests, thus requesting "http://somehost/" instead of
      http://somehost.example.com/. Some commercial proxy servers
      let them get away with this and simply serve the request, implying a
      configured local domain. When the ProxyDomain directive is used and the server is configured for proxy service, Apache httpd can return
      a redirect response and send the client to the correct, fully qualified,
      server address. This is the preferred method since the user's bookmark
      files will then contain fully qualified hosts.
    
    
    top
    

    

    Protocol Adjustments
    
      
    For circumstances where mod_proxy is sending
      requests to an origin server that doesn't properly implement
      keepalives or HTTP/1.1, there are two environment variables that can force the
      request to use HTTP/1.0 with no keepalive. These are set via the
      SetEnv directive.
    

      
    These are the force-proxy-request-1.0 and
      proxy-nokeepalive notes.
    

      
    <Location "/buggyappserver/">
  ProxyPass "http://buggyappserver:7001/foo/"
  SetEnv force-proxy-request-1.0 1
  SetEnv proxy-nokeepalive 1
</Location>
    


      
     In 2.4.26 and later, the "no-proxy" environment variable can be set to disable 
      mod_proxy processing the current request.
      This variable should be set with SetEnvIf, as SetEnv
      is not evaluated early enough.
    

    
    top
    

    

    Request Bodies
    

    
    Some request methods such as POST include a request body.
    The HTTP protocol requires that requests which include a body
    either use chunked transfer encoding or send a
    Content-Length request header.  When passing these
    requests on to the origin server, mod_proxy_http
    will always attempt to send the Content-Length.  But
    if the body is large and the original request used chunked
    encoding, then chunked encoding may also be used in the upstream
    request.  You can control this selection using environment variables.  Setting
    proxy-sendcl ensures maximum compatibility with
    upstream servers by always sending the
    Content-Length, while setting
    proxy-sendchunked minimizes resource usage by using
    chunked encoding.
    

    
    Under some circumstances, the server must spool request bodies
    to disk to satisfy the requested handling of request bodies.  For
    example, this spooling will occur if the original body was sent with
    chunked encoding (and is large), but the administrator has
    asked for backend requests to be sent with Content-Length or as HTTP/1.0.
    This spooling can also occur if the request body already has a
    Content-Length header, but the server is configured to filter incoming
    request bodies.
    

    
    LimitRequestBody only applies to
    request bodies that the server will spool to disk
    

    
    top
    

    

    Reverse Proxy Request Headers
    

    
    When acting in a reverse-proxy mode (using the ProxyPass directive, for example),
    mod_proxy_http adds several request headers in
    order to pass information to the origin server. These headers
    are:
    

    
    
      
    X-Forwarded-For
    
      
    The IP address of the client.
    
      
    X-Forwarded-Host
    
      
    The original host requested by the client in the Host
       HTTP request header.
    
      
    X-Forwarded-Server
    
      
    The hostname of the proxy server.
    
    
    

    
    Be careful when using these headers on the origin server, since
    they will contain more than one (comma-separated) value if the
    original request already contained one of these headers. For
    example, you can use %{X-Forwarded-For}i in the log
    format string of the origin server to log the original clients IP
    address, but you may get more than one address if the request
    passes through several proxies.
    

    
    See also the ProxyPreserveHost and ProxyVia directives, which control
    other request headers.
    

    
    Note:  If you need to specify custom request headers to be
    added to the forwarded request, use the
    RequestHeader
    directive.

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    Compatibility:BalancerGrowth is only available in Apache HTTP Server 2.3.13
  and later.
    

    
    
    This directive allows for growth potential in the number of
    Balancers available for a virtualhost in addition to the
    number pre-configured. It only takes effect if there is at
    least one pre-configured Balancer.

    Module:mod_proxy
    

    Compatibility:BalancerInherit is only available in Apache HTTP Server 2.4.5 and later.
    

    
        
    This directive will cause the current server/vhost to "inherit" ProxyPass
            Balancers and Workers defined in the main server. This can cause issues and
            inconsistent behavior if using the Balancer Manager and so should be disabled
            if using that feature.
    
        
    The setting in the global server defines the default for all vhosts.

    BalancerMember Directive
    

    

    Description:Add a member to a load balancing group

    Context:directory
    

    Status:Extension
    

    Module:mod_proxy
    

    Compatibility:BalancerMember is only available in Apache HTTP Server 2.2
        and later.
    

    
        
    This directive adds a member to a load balancing group. It can be used
            within a <Proxy balancer://...> container
            directive and can take any of the key value pair parameters available to
            ProxyPass directives.
    
        
    One additional parameter is available only to BalancerMember directives:
            loadfactor. This is the member load factor - a decimal number between 1.0
            (default) and 100.0, which defines the weighted load to be applied to the
            member in question.
    
        
    The balancerurl is only needed when not within a
            <Proxy balancer://...>
            container directive. It corresponds to the url of a balancer defined in
            ProxyPass directive.
    
        
    The path component of the balancer URL in any
            <Proxy balancer://...> container directive
            is ignored.
    
        
    Trailing slashes should typically be removed from the URL of a
            BalancerMember.

    This directive will cause the shared memory storage associated
        with the balancers and balancer members to be persisted across
        restarts. This allows these local changes to not be lost during the
        normal restart/graceful state transitions.

    NoProxy Directive
    

    

    Description:Hosts, domains, or networks that will be connected to
directly
    

    Syntax:NoProxy host [host] ...
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    This directive is only useful for Apache httpd proxy servers within
    intranets.  The NoProxy directive specifies a
    list of subnets, IP addresses, hosts and/or domains, separated by
    spaces. A request to a host which matches one or more of these is
    always served directly, without forwarding to the configured
    ProxyRemote proxy server(s).
    

    
    Example
    ProxyRemote  "*"  "http://firewall.example.com:81"
NoProxy         ".example.com" "192.168.112.0/21"
    

    

    
    The host arguments to the NoProxy
    directive are one of the following type list:
    

    
    
    
    
    Domain
    
    
    
    
    A Domain is a partially qualified DNS domain name, preceded
    by a period. It represents a list of hosts which logically belong to the
    same DNS domain or zone (i.e., the suffixes of the hostnames are
    all ending in Domain).
    

    
    Examples
    
      .com .example.org.
    
    

    
    To distinguish Domains from Hostnames (both syntactically and semantically; a DNS domain can
    have a DNS A record, too!), Domains are always written with a
    leading period.
    

    
    Note
    
      
    Domain name comparisons are done without regard to the case, and
      Domains are always assumed to be anchored in the root of the
      DNS tree; therefore, the two domains .ExAmple.com and
      .example.com. (note the trailing period) are considered
      equal. Since a domain comparison does not involve a DNS lookup, it is much
      more efficient than subnet comparison.
    
    
    

    
    
    SubNet
    
    
    
    
    A SubNet is a partially qualified internet address in
    numeric (dotted quad) form, optionally followed by a slash and the netmask,
    specified as the number of significant bits in the SubNet. It is
    used to represent a subnet of hosts which can be reached over a common
    network interface. In the absence of the explicit net mask it is assumed
    that omitted (or zero valued) trailing digits specify the mask. (In this
    case, the netmask can only be multiples of 8 bits wide.) Examples:
    

    
    
    
    192.168 or 192.168.0.0
    
    
    the subnet 192.168.0.0 with an implied netmask of 16 valid bits
    (sometimes used in the netmask form 255.255.0.0)
    
    
    192.168.112.0/21
    
    
    the subnet 192.168.112.0/21 with a netmask of 21
    valid bits (also used in the form 255.255.248.0)
    
    
    

    
    As a degenerate case, a SubNet with 32 valid bits is the
    equivalent to an IPAddr, while a SubNet with zero
    valid bits (e.g., 0.0.0.0/0) is the same as the constant
    _Default_, matching any IP address.
    

    
    
    IPAddr
    
    
    
    
    A IPAddr represents a fully qualified internet address in
    numeric (dotted quad) form. Usually, this address represents a host, but
    there need not necessarily be a DNS domain name connected with the
    address.
    
    
    Example
    
      192.168.123.7
    
    

    
    Note
    
      
    An IPAddr does not need to be resolved by the DNS system, so
      it can result in more effective apache performance.
    
    
    

    
    
    Hostname
    
    
    
    
    A Hostname is a fully qualified DNS domain name which can
    be resolved to one or more IPAddrs via the
    DNS domain name service. It represents a logical host (in contrast to
    Domains, see above) and must be resolvable
    to at least one IPAddr (or often to a list
    of hosts with different IPAddrs).
    

    
    Examples
    
      prep.ai.example.edu
    
      www.example.org
    
    

    
    Note
    
      
    In many situations, it is more effective to specify an IPAddr in place of a Hostname since a
      DNS lookup can be avoided. Name resolution in Apache httpd can take a remarkable
      deal of time when the connection to the name server uses a slow PPP
      link.
    
      
    Hostname comparisons are done without regard to the case,
      and Hostnames are always assumed to be anchored in the root
      of the DNS tree; therefore, the two hosts WWW.ExAmple.com
      and www.example.com. (note the trailing period) are
      considered equal.

    <Proxy> Directive
    

    

    Description:Container for directives applied to proxied resources
    

    Syntax:<Proxy wildcard-url> ...</Proxy>
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    Directives placed in <Proxy>
    sections apply only to matching proxied content.  Shell-style wildcards are
    allowed.
    

    
    For example, the following will allow only hosts in
    yournetwork.example.com to access content via your proxy
    server:
    

    
    <Proxy "*">
  Require host yournetwork.example.com
</Proxy>
    


    
    The following example will process all files in the foo
    directory of example.com through the INCLUDES
    filter when they are sent through the proxy server:
    

   
    <Proxy "http://example.com/foo/*">
  SetOutputFilter INCLUDES
</Proxy>
    


    
    Differences from the Location configuration section
    
      
    A backend URL matches the configuration section if it begins with the
      the wildcard-url string, even if the last path segment in the
      directive only matches a prefix of the backend URL.  For example,
      <Proxy "http://example.com/foo"> matches all of
      http://example.com/foo, http://example.com/foo/bar, and
      http://example.com/foobar.  The matching of the final URL differs
      from the behavior of the <Location> section, which for purposes of this note
      treats the final path component as if it ended in a slash.
    
      
    For more control over the matching, see <ProxyMatch>.

    Status:Extension
    

    Module:mod_proxy
    

    
    
    The ProxyBadHeader directive determines the
    behavior of mod_proxy if it receives syntactically invalid
    response header lines (i.e. containing no colon) from the origin
    server. The following arguments are possible:
    

    
    
    
    IsError
    
    
    Abort the request and end up with a 502 (Bad Gateway) response. This is
    the default behavior.
    

    
    Ignore
    
    
    Treat bad header lines as if they weren't sent.
    

    
    StartBody
    
    
    When receiving the first bad header line, finish reading the headers and
    treat the remainder as body. This helps to work around buggy backend servers
    which forget to insert an empty line between the headers and the body.

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    The ProxyBlock directive specifies a list of
    words, hosts and/or domains, separated by spaces.  HTTP, HTTPS, and
    FTP document requests to sites whose names contain matched words,
    hosts or domains are blocked by the proxy server. The proxy
    module will also attempt to determine IP addresses of list items which
    may be hostnames during startup, and cache them for match test as
    well. That may slow down the startup time of the server.
    

    
    Example
    ProxyBlock "news.example.com" "auctions.example.com" "friends.example.com"
    

    

    
    Note that example would also be sufficient to match any
    of these sites.
    

    
    Hosts would also be matched if referenced by IP address.
    

    
    Note also that
    

    
    ProxyBlock "*"
    


    
    blocks connections to all sites.

    Module:mod_proxy
    

    
    
    This directive is only useful for Apache httpd proxy servers within
    intranets. The ProxyDomain directive specifies
    the default domain which the apache proxy server will belong to. If a
    request to a host without a domain name is encountered, a redirection
    response to the same host with the configured Domain appended
    will be generated.
    

    
    Example
    ProxyRemote  "*"  "http://firewall.example.com:81"
NoProxy         ".example.com" "192.168.112.0/21"

    Status:Extension
    

    Module:mod_proxy
    

    Compatibility:The list of status codes was added in 2.5.1
    

    
    
    This directive is useful for reverse-proxy setups where you want to
    have a common look and feel on the error pages seen by the end user.
    This also allows for included files (via
    mod_include's SSI) to get
    the error code and act accordingly. (Default behavior would display
    the error page of the proxied server. Turning this on shows the SSI
    Error message.)
    

    
    This directive does not affect the processing of informational (1xx),
    normal success (2xx), or redirect (3xx) responses.
    

    
    By default ProxyErrorOverride affects all responses with codes between 400 (including)
        and 600 (excluding).
    

    
    Example for default behavior
    ProxyErrorOverride  On
    

    

    
    To change the default behavior, you can specify the status codes to consider, separated by spaces.
        If you do so, all other status codes will be ignored.
        You can only specify status codes, that are considered error codes: between 400 (including)
        and 600 (excluding).
    

    
    Example for custom status codes
    ProxyErrorOverride  On 403 405 500 501 502 503 504

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    The ProxyIOBufferSize directive adjusts the size
    of the internal buffer which is used as a scratchpad for the data between
    input and output. The size must be at least 512.
    

    
    In almost every case, there's no reason to change that value.
    

    
    If used with AJP, this directive sets the maximum AJP packet size in
    bytes. Values larger than 65536 are set to 65536. If you change it from
    the default, you must also change the packetSize attribute of
    your AJP connector on the Tomcat side! The attribute
    packetSize is only available in Tomcat 5.5.20+
    and 6.0.2+
    

    
    Normally it is not necessary to change the maximum packet size.
    Problems with the default value have been reported when sending
    certificates or certificate chains.

    The <ProxyMatch> directive is
    identical to the <Proxy> directive, except that it matches URLs
    using regular expressions.
    

    
    From 2.4.8 onwards, named groups and backreferences are captured and
    written to the environment with the corresponding name prefixed with
    "MATCH_" and in upper case. This allows elements of URLs to be referenced
    from within expressions and modules like
    mod_rewrite. In order to prevent confusion, numbered
    (unnamed) backreferences are ignored. Use named groups instead.

    Default:ProxyMaxForwards -1

    Status:Extension
    

    Module:mod_proxy
    

    Compatibility:Default behaviour changed in 2.2.7
    

    
    
    The ProxyMaxForwards directive specifies the
    maximum number of proxies through which a request may pass if there's no
    Max-Forwards header supplied with the request. This may
    be set to prevent infinite proxy loops or a DoS attack.
    

    
    Example
    ProxyMaxForwards 15
    

    

    
    Note that setting ProxyMaxForwards is a
    violation of the HTTP/1.1 protocol (RFC2616), which forbids a Proxy
    setting Max-Forwards if the Client didn't set it.
    Earlier Apache httpd versions would always set it.  A negative
    ProxyMaxForwards value, including the
    default -1, gives you protocol-compliant behavior but may
    leave you open to loops.

    Module:mod_proxy
    

    Compatibility:Unix Domain Socket (UDS) support added in 2.4.7
    

    
    
    This directive allows remote servers to be mapped into the
    space of the local server. The local server does not act as a
    proxy in the conventional sense but appears to be a mirror of the
    remote server. The local server is often called a reverse
    proxy or gateway. The path is the name of
    a local virtual path; url is a partial URL for the
    remote server and cannot include a query string.
    

    
    It is strongly suggested to review the concept of a
    Worker before proceeding any further
    with this section.
    

    
    This directive is not supported within
    <Directory>,
    <If> and
    <Files> containers.
    
    

    
    The ProxyRequests directive should
    usually be set off when using
    ProxyPass.
    

    
    In 2.4.7 and later, support for using a Unix Domain Socket is available by using a target
    which prepends unix:/path/lis.sock|. For example, to proxy
    HTTP and target the UDS at /home/www.socket, you would use
    unix:/home/www.socket|http://localhost/whatever/.
    

    
    Note: The path associated with the unix:
    URL is DefaultRuntimeDir aware.
    

    
    When used inside a <Location> section, the first argument is omitted and the local
    directory is obtained from the <Location>. The same will occur inside a
    <LocationMatch> section;
    however, ProxyPass does not interpret the regexp as such, so it is necessary
    to use ProxyPassMatch in this situation instead.
    

    
    Suppose the local server has address http://example.com/;
    then
    

    
    <Location "/mirror/foo/">
    ProxyPass "http://backend.example.com/"
</Location>
    


    
    will cause a local request for
    http://example.com/mirror/foo/bar to be internally converted
    into a proxy request to http://backend.example.com/bar.
    

    
    If you require a more flexible reverse-proxy configuration, see the
    RewriteRule directive with the
    [P] flag.
    

    
    The following alternative syntax is possible; however, it can carry a
    performance penalty when present in very large numbers. The advantage of
    the below syntax is that it allows for dynamic control via the
    Balancer Manager interface:
    

    
    ProxyPass "/mirror/foo/" "http://backend.example.com/"
    


    
    
    
    If the first argument ends with a trailing /, the second
       argument should also end with a trailing /, and vice
       versa. Otherwise, the resulting requests to the backend may miss some
       needed slashes and do not deliver the expected results.
    
    
    
    

    
    The ! directive is useful in situations where you don't want
    to reverse-proxy a subdirectory, e.g.
    

    
    <Location "/mirror/foo/">
    ProxyPass "http://backend.example.com/"
</Location>
<Location "/mirror/foo/i">
    ProxyPass "!"
</Location>
    


    
    ProxyPass "/mirror/foo/i" "!"
ProxyPass "/mirror/foo" "http://backend.example.com"
    


    
    will proxy all requests to /mirror/foo to
    backend.example.com except requests made to
    /mirror/foo/i.
    

    
    Mixing ProxyPass settings in different contexts does not work:
    
    
    ProxyPass "/mirror/foo/i" "!"
<Location "/mirror/foo/">
    ProxyPass "http://backend.example.com/"
</Location>
    

    
    In this case, a request to /mirror/foo/i will get proxied,
       because the ProxyPass directive in the Location block will be evaluated
       first. The fact that ProxyPass supports both server and directory contexts
       does not mean that their scope and position in the configuration file will
       guarantee any ordering or override.
    

    
    Ordering ProxyPass Directives
    
      
    The configured ProxyPass
      and ProxyPassMatch
      rules are checked in the order of configuration. The first rule that
      matches wins. So usually you should sort conflicting
      ProxyPass rules starting with the
      longest URLs first. Otherwise, later rules for longer URLS will be hidden
      by any earlier rule which uses a leading substring of the URL. Note that
      there is some relation with worker sharing.
    
    
    
    
    Ordering ProxyPass Directives in Locations
    
      
    Only one ProxyPass directive
      can be placed in a Location block,
      and the most specific location will take precedence.
    
    
    
    
    Exclusions and the no-proxy environment variable
    
      
    Exclusions must come before the
      general ProxyPass directives. In 2.4.26 and later, the "no-proxy"
      environment variable is an alternative to exclusions, and is the only
      way to configure an exclusion of a ProxyPass
      directive in Location context. 
      This variable should be set with SetEnvIf, as SetEnv
      is not evaluated early enough.
      
    

    
     

    
    ProxyPass key=value Parameters
    

    
    In Apache HTTP Server 2.1 and later, mod_proxy supports pooled
    connections to a backend server.  Connections created on demand
    can be retained in a pool for future use.  Limits on the pool size
    and other settings can be coded on
    the ProxyPass directive
    using  key=value parameters, described in the tables
    below.
    

    
    Maximum connections to the backend
    
    
    By default, mod_proxy will allow and retain the maximum number of
    connections that could be used simultaneously by that web server child
    process.  Use the max parameter to reduce the number from
    the default. The pool of connections is maintained per web server child
    process, and max and other settings are not coordinated
    among all child processes, except when only one child process is allowed
    by configuration or MPM design.
    
    
    

    
    Use the ttl parameter to set an optional
    time to live; connections which have been unused for at least
    ttl seconds will be closed.  ttl can be used
    to avoid using a connection which is subject to closing because of the
    backend server's keep-alive timeout.
    

    
    Example
    ProxyPass "/example" "http://backend.example.com" max=20 ttl=120 retry=300
    

    

    
    Worker|BalancerMember parameters
    
    
    
    
    Parameter
        Default
        Description
    
    
    min
        0
        Minimum number of connection pool entries, unrelated to the
    actual number of connections.  This only needs to be modified from the
    default for special circumstances where heap memory associated with the
    backend connections should be preallocated or retained.
    
    
    max
        1...n
        Maximum number of connections that will be allowed to the
    backend server. The default for this limit is the number of threads
    per process in the active MPM. In the Prefork MPM, this is always 1,
    while with other MPMs, it is controlled by the
    ThreadsPerChild directive.
    
    
    smax
        max
        Retained connection pool entries above this limit are freed
    during certain operations if they have been unused for longer than
    the time to live, controlled by the ttl parameter.  If
    the connection pool entry has an associated connection, it will be
    closed.  This only needs to be modified from the default for special
    circumstances where connection pool entries and any associated
    connections which have exceeded the time to live need to be freed or
    closed more aggressively.
    
    
    acquire
        -
        If set, this will be the maximum time to wait for a free
    connection in the connection pool, in milliseconds. If there are no free
    connections in the pool, the Apache httpd will return SERVER_BUSY
    status to the client.
    
    
    
    connectiontimeout
        timeout
        Connect timeout in seconds.
        The number of seconds Apache httpd waits for the creation of a connection to
        the backend to complete. By adding a postfix of ms, the timeout can be
        also set in milliseconds.
    
    
    
    disablereuse
        Off
        This parameter should be used when you want to force mod_proxy
    to immediately close a connection to the backend after being used, and
    thus, disable its persistent connection and pool for that backend.
    This helps in various situations where a firewall between Apache
    httpd and
    the backend server (regardless of protocol) tends to silently
    drop connections or when backends themselves may be under round-
    robin DNS.
    When connection reuse is enabled each backend domain is resolved
    (with a DNS query) only once per child process and cached for all further
    connections until the child is recycled. To disable connection reuse,
    set this property value to On.
    
    
    
    enablereuse
        On
        This is the inverse of 'disablereuse' above, provided as a
        convenience for scheme handlers that require opt-in for connection
        reuse (such as mod_proxy_fcgi).  2.4.11 and later only.
    
    
    
    flushpackets
        off
        Determines whether the proxy module will auto-flush the output
        brigade after each "chunk" of data. 'off' means that it will flush
        only when needed; 'on' means after each chunk is sent; and
        'auto' means poll/wait for a period of time and flush if
        no input has been received for 'flushwait' milliseconds.
        Currently, this is in effect only for mod_proxy_ajp and mod_proxy_fcgi.
    
    
    
    flushwait
        10
        The time to wait for additional input, in milliseconds, before
        flushing the output brigade if 'flushpackets' is 'auto'.
    
    
    
    iobuffersize
        8192
        Adjusts the size of the internal scratchpad IO buffer. This allows you
        to override the ProxyIOBufferSize for a specific worker.
        This must be at least 512 or set to 0 for the system default of 8192.
    
    
    
    responsefieldsize
        8192
        Adjust the size of the proxy response field buffer. The buffer size
            should be at least the size of the largest expected header size from
            a proxied response. Setting the value to 0 will use the system
            default of 8192 bytes.
    
        Available in Apache HTTP Server 2.4.34 and later.
    
    
    
    keepalive
        Off
        
    This parameter should be used when you have a firewall between your
    Apache httpd and the backend server, which tends to drop inactive connections.
    This flag will tell the Operating System to send KEEP_ALIVE
    messages on inactive connections and thus prevent the firewall from dropping
    the connection.
    To enable keepalive, set this property value to On. 
    
    
    The frequency of initial and subsequent TCP keepalive probes
    depends on global OS settings, and may be as high as 2 hours. To be useful,
    the frequency configured in the OS must be smaller than the threshold used
    by the firewall.
    
    
    
    
    lbset
        0
        Sets the load balancer cluster set that the worker is a member
         of. The load balancer will try all members of a lower numbered
         lbset before trying higher numbered ones.
    
    
    
    ping
        0
        Ping property tells the webserver to "test" the connection to
        the backend before forwarding the request. For AJP, it causes
        mod_proxy_ajp to send a CPING
        request on the ajp13 connection (implemented on Tomcat 3.3.2+, 4.1.28+
        and 5.0.13+). For HTTP, it causes mod_proxy_http
        to send a 100-Continue to the backend (only valid for
        HTTP/1.1 - for non HTTP/1.1 backends, this property has no
        effect). In both cases, the parameter is the delay in seconds to wait
        for the reply.
        This feature has been added to avoid problems with hung and
        busy backends.
        This will increase the network traffic during the normal operation
        which could be an issue, but it will lower the
        traffic in case some of the cluster nodes are down or busy.
        By adding a postfix of ms, the delay can be also set in
        milliseconds.
    
    
    
    receivebuffersize
        0
        Adjusts the size of the explicit (TCP/IP) network buffer size for
        proxied connections. This allows you to override the
        ProxyReceiveBufferSize for a specific worker.
        This must be at least 512 or set to 0 for the system default.
    
    
    
    redirect
        -
        Redirection Route of the worker. This value is usually
        set dynamically to enable safe removal of the node from
        the cluster. If set, all requests without session id will be
        redirected to the BalancerMember that has route parameter
        equal to this value.
    
    
    
    retry
        60
        Connection pool worker retry timeout in seconds.
    If the connection pool worker to the backend server is in the error state,
    Apache httpd will not forward any requests to that server until the timeout
    expires. This enables to shut down the backend server for maintenance
    and bring it back online later. A value of 0 means always retry workers
    in an error state with no timeout.
    
    
    
    route
        -
        Route of the worker when used inside load balancer.
        The route is a value appended to session id.
    
    
    
    status
        -
        Single letter value defining the initial status of
        this worker.
        
    
         
    D: Worker is disabled and will not accept any requests.
    
         
    S: Worker is administratively stopped.
    
         
    I: Worker is in ignore-errors mode and will always be considered available.
    
         
    R: Worker is a hot spare. For each worker in a given lbset that is unusable
                    (draining, stopped, in error, etc.), a usable hot spare with the same lbset will be used in
                    its place. Hot spares can help ensure that a specific number of workers are always available
                    for use by a balancer.
    
         
    H: Worker is in hot-standby mode and will only be used if no other
                    viable workers or spares are available in the balancer set.
    
         
    E: Worker is in an error state.
    
         
    N: Worker is in drain mode and will only accept existing sticky sessions
                    destined for itself and ignore all other requests.
    
        
    Status
        can be set (which is the default) by prepending with '+' or
        cleared by prepending with '-'.
        Thus, a setting of 'S-E' sets this worker to Stopped and
        clears the in-error flag.
    
    
    
    timeout
        ProxyTimeout
        Connection timeout in seconds.
        The number of seconds Apache httpd waits for data sent by / to the backend.
    
    
    
    ttl
        -
        Time to live for inactive connections and associated connection
        pool entries, in seconds.  Once reaching this limit, a
        connection will not be used again; it will be closed at some
        later time.
    
    
    
    flusher
        flush
        
    Name of the provider used by mod_proxy_fdpass.
        See the documentation of this module for more details.
    
    
    
    
    secret
        -
        Value of secret used by mod_proxy_ajp.
        It must be identical to the secret configured on the server side of the
        AJP connection.
    
        Available in Apache HTTP Server 2.4.42 and later.
    
    
    
    upgrade
        WebSocket
        
    Protocol accepted in the Upgrade header by mod_proxy_wstunnel.
        See the documentation of this module for more details.
    
    
    
    
    mapping
        -
        
    Type of mapping between the path and the url.
        This determines the normalization and/or (non-)decoding that mod_proxy
        will apply to the requested uri-path before matching the path. If
        a mapping matches, it's committed to the uri-path such that all the directory
        contexts that use a path (like <Location>) will be matched using the
        same mapping.
    
        
    mapping=encoded prevents the %-decoding of the uri-path so
        that one can match for instance /some%2furi%2fpath%2fwith%2fslash in a
        ProxyPass or in a <Location> context.
    
        
    mapping=servlet refers to the normalization defined by the Servlet
        specification, which is for instance applied by Apache Tomcat for servlet containers
        (notably the path parameters are ignored for the mapping). An uri-path like
        /some;foo/path is then mapped as /some/path hence matches:
    
        
      <Location /some/path> or:
    
        
      ProxyPass "/some/path" "https://tomcat.example.com/some/path"
    
        
    regardless of the requested path parameters.
    
    
    Note
    
        
    It is recommended to use the same mapping on the Apache httpd side than the one
        used on the backend side. For instance when configuring authorizations in
        <Location> blocks for paths that are mapped by mod_proxy
        to some servlet containers (like applications running on Apache Tomcat), one should
        use the mapping=servlet setting to prevent path parameters and alike from
        interfering with the authorizations that are to be enforced in by the Apache httpd.
    
    
    
    
    

    
    

    
    If the Proxy directive scheme starts with the
    balancer:// (eg: balancer://cluster,
    any path information is ignored), then a virtual worker that does not really
    communicate with the backend server will be created. Instead, it is responsible
    for the management of several "real" workers. In that case, the special set of
    parameters can be added to this virtual worker. 
    See mod_proxy_balancer for more information about how 
    the balancer works.
    
    
    
    Balancer parameters
    
    
    
    
    Parameter
        Default
        Description
    
    
    lbmethod
        byrequests
        Balancer load-balance method. Select the load-balancing scheduler
        method to use. Either byrequests, to perform weighted
        request counting; bytraffic, to perform weighted
        traffic byte count balancing; or bybusyness, to perform
        pending request balancing. The default is byrequests.
    
    
    
    maxattempts
        One less than the number of workers, or 1 with a single worker.
        Maximum number of failover attempts before giving up.
    
    
    
    nofailover
        Off
        If set to On, the session will break if the worker is in
        error state or disabled. Set this value to On if backend
        servers do not support session replication.
    
    
    
    stickysession
        -
        Balancer sticky session name. The value is usually set to something
        like JSESSIONID or PHPSESSIONID,
        and it depends on the backend application server that support sessions.
        If the backend application server uses different name for cookies
        and url encoded id (like servlet containers) use | to separate them.
        The first part is for the cookie the second for the path.
    
        Available in Apache HTTP Server 2.4.4 and later.
    
    
    
    stickysessionsep
        "."
        Sets the separation symbol in the session cookie. Some backend application servers
        do not use the '.' as the symbol. For example, the Oracle Weblogic server uses
        '!'. The correct symbol can be set using this option. The setting of 'Off'
        signifies that no symbol is used.
    
    
    
    scolonpathdelim
        Off
        If set to On, the semi-colon character ';' will be
        used as an additional sticky session path delimiter/separator. This
        is mainly used to emulate mod_jk's behavior when dealing with paths such
        as JSESSIONID=6736bcf34;foo=aabfa
    
    
    
    timeout
        0
        Balancer timeout in seconds. If set, this will be the maximum time
        to wait for a free worker. The default is to not wait.
    
    
    
    failonstatus
        -
        A single or comma-separated list of HTTP status codes. If set, this will
        force the worker into error state when the backend returns any status code
        in the list. Worker recovery behaves the same as other worker errors.
    
    
    
    failontimeout
        Off
        If set, an IO read timeout after a request is sent to the backend will
        force the worker into error state. Worker recovery behaves the same as other
        worker errors.
    
        Available in Apache HTTP Server 2.4.5 and later.
    
    
    
    nonce
        <auto>
        The protective nonce used in the balancer-manager application page.
        The default is to use an automatically determined UUID-based
        nonce, to provide for further protection for the page. If set,
        then the nonce is set to that value. A setting of None
        disables all nonce checking.
    
    Note
    
      
    In addition to the nonce, the balancer-manager page
      should be protected via an ACL.
    
    
    
     
    
    
    growth
        0
        Number of additional BalancerMembers to allow to be added
        to this balancer in addition to those defined at configuration.
    
    
    
    forcerecovery
        On
        Force the immediate recovery of all workers without considering the
        retry parameter of the workers if all workers of a balancer are
        in error state. There might be cases where an already overloaded backend
        can get into deeper trouble if the recovery of all workers is enforced
        without considering the retry parameter of each worker. In this case,
        set to Off.
    
        Available in Apache HTTP Server 2.4.2 and later.
    
    

    
    
    
    A sample balancer setup:
    
    
    ProxyPass "/special-area" "http://special.example.com" smax=5 max=10
ProxyPass "/" "balancer://mycluster/" stickysession=JSESSIONID|jsessionid nofailover=On
<Proxy "balancer://mycluster">
    BalancerMember "ajp://1.2.3.4:8009"
    BalancerMember "ajp://1.2.3.5:8009" loadfactor=20
    # Less powerful server, don't send as many requests there,
    BalancerMember "ajp://1.2.3.6:8009" loadfactor=5
</Proxy>
    


    
    Configuring hot spares can help ensure that a certain number of
    workers are always available for use per load balancer set:
    
    
    ProxyPass "/" "balancer://sparecluster/"
<Proxy balancer://sparecluster>
    BalancerMember ajp://1.2.3.4:8009
    BalancerMember ajp://1.2.3.5:8009
    # The servers below are hot spares. For each server above that is unusable
    # (draining, stopped, unreachable, in error state, etc.), one of these spares
    # will be used in its place. Two servers will always be available for a request
    # unless one or more of the spares is also unusable.
    BalancerMember ajp://1.2.3.6:8009 status=+R
    BalancerMember ajp://1.2.3.7:8009 status=+R
</Proxy>
    


    
    Setting up a hot-standby that will only be used if no other
    members (or spares) are available in the load balancer set:
    
    
    ProxyPass "/" "balancer://hotcluster/"
<Proxy "balancer://hotcluster">
    BalancerMember "ajp://1.2.3.4:8009" loadfactor=1
    BalancerMember "ajp://1.2.3.5:8009" loadfactor=2.25
    # The server below is on hot standby
    BalancerMember "ajp://1.2.3.6:8009" status=+H
    ProxySet lbmethod=bytraffic
</Proxy>
    


    
    Additional ProxyPass Keywords
    

    
    Normally, mod_proxy will canonicalise ProxyPassed URLs.
    But this may be incompatible with some backends, particularly those
    that make use of PATH_INFO.  The optional nocanon
    keyword suppresses this and passes the URL path "raw" to the
    backend.  Note that this keyword may affect the security of your backend,
    as it removes the normal limited protection against URL-based attacks
    provided by the proxy.
    

    
    Normally, mod_proxy will include the query string when
    generating the SCRIPT_FILENAME environment variable.
    The optional noquery keyword (available in
    httpd 2.4.1 and later) prevents this.
    

    
    The optional interpolate keyword, in combination with
    ProxyPassInterpolateEnv, causes the ProxyPass
    to interpolate environment variables, using the syntax
    ${VARNAME}.  Note that many of the standard CGI-derived
    environment variables will not exist when this interpolation happens,
    so you may still have to resort to mod_rewrite
    for complex rules. Also note that interpolation is supported
    within the scheme/hostname/port portion of a URL only for variables that
    are available when the directive is parsed 
    (like Define). Dynamic determination of
    those fields can be accomplished with mod_rewrite.
    The following example describes how to use mod_rewrite
    to dynamically set the scheme to http or https:
    

    
    RewriteEngine On

RewriteCond "%{HTTPS}" =off
RewriteRule "." "-" [E=protocol:http]
RewriteCond "%{HTTPS}" =on
RewriteRule "." "-" [E=protocol:https]

RewriteRule "^/mirror/foo/(.*)" "%{ENV:protocol}://backend.example.com/$1" [P]
ProxyPassReverse  "/mirror/foo/" "http://backend.example.com/"
ProxyPassReverse  "/mirror/foo/" "https://backend.example.com/"

    This directive will cause the current server/vhost to "inherit"
            ProxyPass
            directives defined in the main server. This can cause issues and
            inconsistent behavior if using the Balancer Manager for dynamic changes
            and so should be disabled if using that feature.
    
        
    The setting in the global server defines the default for all vhosts.
    
        
    Disabling ProxyPassInherit also disables BalancerInherit.

    This directive, together with the interpolate argument to
    ProxyPass, ProxyPassReverse,
    ProxyPassReverseCookieDomain, and
    ProxyPassReverseCookiePath,
    enables reverse proxies to be dynamically
    configured using environment variables which may be set by
    another module such as mod_rewrite.
    It affects the ProxyPass,
    ProxyPassReverse,
    ProxyPassReverseCookieDomain, and
    ProxyPassReverseCookiePath directives
    and causes them to substitute the value of an environment
    variable varname for the string ${varname}
    in configuration directives if the interpolate option is set.
    
    
    The scheme/hostname/port portion of ProxyPass may
    contain variables, but only the ones available when the directive is parsed
    (for example, using Define).
    For all the other use cases, please consider using
    mod_rewrite instead.
    
    
    Performance warning
    
    
    Keep this turned off unless you need it!
    Adding variables to ProxyPass for example may lead to
    the use of the default mod_proxy's workers configured (that don't allow any fine
    tuning like connections reuse, etc..).

    ProxyPassMatch Directive
    

    

    Description:Maps remote servers into the local server URL-space using regular expressions
    

    Syntax:ProxyPassMatch [regex] !|url [key=value
	[key=value ...]]
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    This directive is equivalent to ProxyPass
       but makes use of regular expressions instead of simple prefix matching. The
       supplied regular expression is matched against the url, and if it
       matches, the server will substitute any parenthesized matches into the given
       string and use it as a new url.
    

    
    Note: This directive cannot be used within a
    <Directory> context.
    
    
    
    Suppose the local server has address http://example.com/;
    then
    

    
    ProxyPassMatch "^/(.*\.gif)$" "http://backend.example.com/$1"
    


    
    will cause a local request for
    http://example.com/foo/bar.gif to be internally converted
    into a proxy request to http://backend.example.com/foo/bar.gif.
    
    
    Note
    
      
    The URL argument must be parsable as a URL before regexp
      substitutions (as well as after).  This limits the matches you can use.
      For instance, if we had used
    
      
    ProxyPassMatch "^(/.*\.gif)$" "http://backend.example.com:8000$1"
    

      
    in our previous example, it would fail with a syntax error
      at server startup.  This is a bug (PR 46665 in the ASF bugzilla),
      and the workaround is to reformulate the match:
    
      
    ProxyPassMatch "^/(.*\.gif)$" "http://backend.example.com:8000/$1"
    

    
    
    
    The ! directive is useful in situations where you don't want
    to reverse-proxy a subdirectory.
    

    
    When used inside a <LocationMatch> section, the first argument is omitted and the
    regexp is obtained from the <LocationMatch>.
    

    
    If you require a more flexible reverse-proxy configuration, see the
    RewriteRule directive with the
    [P] flag.
    

    
    
      
    Default Substitution
    
      
    When the URL parameter doesn't use any backreferences into the regular
      expression, the original URL will be appended to the URL parameter.
      
    
    
    

    
    
      
    Security Warning
    
      
    Take care when constructing the target URL of the rule, considering
        the security impact from allowing the client influence over the set of
        URLs to which your server will act as a proxy.  Ensure that the scheme
        and hostname part of the URL is either fixed or does not allow the
        client undue influence.

    ProxyPassReverse Directive
    

    

    Description:Adjusts the URL in HTTP response headers sent from a reverse
proxied server
    

    Syntax:ProxyPassReverse [path] url
[interpolate]
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    This directive lets Apache httpd adjust the URL in the Location,
    Content-Location and URI headers on HTTP
    redirect responses. This is essential when Apache httpd is used as a
    reverse proxy (or gateway) to avoid bypassing the reverse proxy
    because of HTTP redirects on the backend servers which stay behind
    the reverse proxy.
    

    
    Only the HTTP response headers specifically mentioned above
    will be rewritten. Apache httpd will not rewrite other response
    headers, nor will it by default rewrite URL references inside HTML pages.
    This means that if the proxied content contains absolute URL
    references, they will bypass the proxy. To rewrite HTML content to
    match the proxy, you must load and enable mod_proxy_html.
    
    

    
    path is the name of a local virtual path; url is a
    partial URL for the remote server. 
    These parameters are used the same way as for the
    ProxyPass directive.
    

    
    For example, suppose the local server has address
    http://example.com/; then
    

    
    ProxyPass         "/mirror/foo/" "http://backend.example.com/"
ProxyPassReverse  "/mirror/foo/" "http://backend.example.com/"
ProxyPassReverseCookieDomain  "backend.example.com"  "public.example.com"
ProxyPassReverseCookiePath  "/"  "/mirror/foo/"
    


    
    will not only cause a local request for the
    http://example.com/mirror/foo/bar to be internally converted
    into a proxy request to http://backend.example.com/bar
    (the functionality which ProxyPass provides here).
    It also takes care of redirects which the server backend.example.com
    sends when redirecting http://backend.example.com/bar to
    http://backend.example.com/quux . Apache httpd adjusts this to
    http://example.com/mirror/foo/quux before forwarding the HTTP
    redirect response to the client. Note that the hostname used for
    constructing the URL is chosen in respect to the setting of the UseCanonicalName directive.
    

    
    Note that this ProxyPassReverse directive can
    also be used in conjunction with the proxy feature
    (RewriteRule ...  [P]) from mod_rewrite
    because it doesn't depend on a corresponding ProxyPass directive.
    

    
    The optional interpolate keyword, used together with
    ProxyPassInterpolateEnv, enables interpolation
    of environment variables specified using the format ${VARNAME}.
    Note that interpolation is not supported within the scheme portion of a
    URL.
    

    
    When used inside a <Location> section, the first argument is omitted and the local
    directory is obtained from the <Location>. The same occurs inside a <LocationMatch> section, but will probably not work as
    intended, as ProxyPassReverse will interpret the regexp literally as a
    path; if needed in this situation, specify the ProxyPassReverse outside
    the section or in a separate <Location> section.
    

    
    This directive is not supported in <Directory> or <Files> sections.

    ProxyPassReverseCookieDomain Directive
    

    

    Description:Adjusts the Domain string in Set-Cookie headers from a reverse-
proxied server
    

    Syntax:ProxyPassReverseCookieDomain internal-domain
public-domain [interpolate]
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy
    

    

    Usage is basically similar to
ProxyPassReverse, but instead of
rewriting headers that are a URL, this rewrites the domain
string in Set-Cookie headers.
    


    

    top
    

    ProxyPassReverseCookiePath Directive
    

    

    Description:Adjusts the Path string in Set-Cookie headers from a reverse-
proxied server
    

    Syntax:ProxyPassReverseCookiePath internal-path
public-path [interpolate]
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy
    

    

    
Useful in conjunction with
ProxyPassReverse
in situations where backend URL paths are mapped to public paths on the
reverse proxy. This directive rewrites the path string in
Set-Cookie headers. If the beginning of the cookie path matches
internal-path, the cookie path will be replaced with
public-path.

    
In the example given with
ProxyPassReverse, the directive:

    
    
    ProxyPassReverseCookiePath  "/"  "/mirror/foo/"
    


    
will rewrite a cookie with backend path / (or
/example or, in fact, anything) to /mirror/foo/.

    


    

    top
    

    ProxyPreserveHost Directive
    

    

    Description:Use incoming Host HTTP request header for proxy
request
    

    Syntax:ProxyPreserveHost On|Off
    

    Default:ProxyPreserveHost Off
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy
    

    Compatibility:Usable in directory
context in 2.3.3 and later.
    

    
    
    When enabled, this option will pass the Host: line from the incoming
    request to the proxied host, instead of the hostname specified in the
    ProxyPass line.
    

    
    This option should normally be turned Off. It is mostly
    useful in special configurations like proxied mass name-based virtual
    hosting, where the original Host header needs to be evaluated by the
    backend server.

    ProxyReceiveBufferSize Directive
    

    

    Description:Network buffer size for proxied HTTP and FTP
connections
    

    Syntax:ProxyReceiveBufferSize bytes
    

    Default:ProxyReceiveBufferSize 0
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    The ProxyReceiveBufferSize directive specifies an
    explicit (TCP/IP) network buffer size for proxied HTTP and FTP connections,
    for increased throughput. It has to be greater than 512 or set
    to 0 to indicate that the system's default buffer size should
    be used.
    

    
    Example
    ProxyReceiveBufferSize 2048

    ProxyRemote Directive
    

    

    Description:Remote proxy used to handle certain requests
    

    Syntax:ProxyRemote match remote-server
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    This defines remote proxies to this proxy. match is either the
    name of a URL-scheme that the remote server supports, or a partial URL
    for which the remote server should be used, or * to indicate
    the server should be contacted for all requests. remote-server is
    a partial URL for the remote server. Syntax:
    

    
    
      remote-server =
          scheme://hostname[:port]
    
    

    
    scheme is effectively the protocol that should be used to
    communicate with the remote server; only http and https
    are supported by this module. When using https, the requests
    are forwarded through the remote proxy using the HTTP CONNECT method.
    

    
    Example
    ProxyRemote "http://goodguys.example.com/" "http://mirrorguys.example.com:8000"
ProxyRemote "*" "http://cleverproxy.localdomain"
ProxyRemote "ftp" "http://ftpproxy.mydomain:8080"
    

    

    
    In the last example, the proxy will forward FTP requests, encapsulated
    as yet another HTTP proxy request, to another proxy which can handle
    them.
    

    
    This option also supports reverse proxy configuration; a backend
    webserver can be embedded within a virtualhost URL space even if that
    server is hidden by another forward proxy.
    


    

    top
    

    ProxyRemoteMatch Directive
    

    

    Description:Remote proxy used to handle requests matched by regular
expressions
    

    Syntax:ProxyRemoteMatch regex remote-server
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    The ProxyRemoteMatch is identical to the
    ProxyRemote directive, except that
    the first argument is a regular expression
    match against the requested URL.

    ProxyRequests Directive
    

    

    Description:Enables forward (standard) proxy requests
    

    Syntax:ProxyRequests On|Off
    

    Default:ProxyRequests Off
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy
    

    
    
    This allows or prevents Apache httpd from functioning as a forward proxy
    server. (Setting ProxyRequests to Off does not disable use of
    the ProxyPass directive.)
    

    
    In a typical reverse proxy or gateway configuration, this
    option should be set to
    Off.
    

    
    In order to get the functionality of proxying HTTP or FTP sites, you
    need also mod_proxy_http or mod_proxy_ftp
    (or both) present in the server.
    

    
    In order to get the functionality of (forward) proxying HTTPS sites, you
    need mod_proxy_connect enabled in the server.
    

    
    Warning
    
      
    Do not enable proxying with ProxyRequests until you have secured your server.  Open proxy servers are dangerous
      both to your network and to the Internet at large.

    Module:mod_proxy
    

    Compatibility:ProxySet is only available in Apache HTTP Server 2.2
  and later.
    

    
    
    This directive is used as an alternate method of setting any of the
    parameters available to Proxy balancers and workers normally done via the
    ProxyPass directive. If used
    within a <Proxy balancer url|worker url>
    container directive, the url argument is not required. As a side
    effect the respective balancer or worker gets created. This can be useful
    when doing reverse proxying via a
    RewriteRule instead of a
    ProxyPass directive.
    

    
    <Proxy "balancer://hotcluster">
    BalancerMember "http://www2.example.com:8080" loadfactor=1
    BalancerMember "http://www3.example.com:8080" loadfactor=2
    ProxySet lbmethod=bytraffic
</Proxy>
    

    

    
    <Proxy "http://backend">
    ProxySet keepalive=On

    ProxySet "balancer://foo" lbmethod=bytraffic timeout=15
    


    
    ProxySet "ajp://backend:7001" timeout=15
    


   
    Warning
    
      
    Keep in mind that the same parameter key can have a different meaning
      depending whether it is applied to a balancer or a worker, as shown by
      the two examples above regarding timeout.

    This directive allows a user to specify a timeout on proxy requests.

    proxy requests along a chain of proxy servers.  See RFC 2616 (HTTP/1.1), section
    14.45 for an explanation of Via: header lines.
    

    
      
    
    • If set to Off, which is the default, no special processing
    is performed. If a request or reply contains a Via: header,
    it is passed through unchanged.
      • 

    
    • If set to On, each request and reply will get a
    Via: header line added for the current host.
      • 

    
    • If set to Full, each generated Via: header
    line will additionally have the Apache httpd server version shown as a
    Via: comment field.
      • 

    
    • If set to Block, every proxy request will have all its
    Via: header lines removed. No new Via: header will
    be generated.

    Description:Allows "anonymous" user access to authenticated
    areas
    

    Status:Extension
    

    Module Identifier:authn_anon_module
    

    Source File:mod_authn_anon.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module provides authentication front-ends such as
    mod_auth_basic to authenticate users similar
    to anonymous-ftp sites, i.e. have a 'magic' user id
    'anonymous' and the email address as a password. These email
    addresses can be logged.
    

    
    Combined with other (database) access control methods, this
    allows for effective user tracking and customization according
    to a user profile while still keeping the site open for
    'unregistered' users. One advantage of using Auth-based user
    tracking is that, unlike magic-cookies and funny URL
    pre/postfixes, it is completely browser independent and it
    allows users to share URLs.
    

    
    When using mod_auth_basic, this module is invoked
    via the AuthBasicProvider
    directive with the anon value.
    

    


    top
    

    

    Example
    
    
    The example below is combined with "normal" htpasswd-file based
    authentication and allows users in additionally as 'guests' with the
    following properties:
    

    
      
      
    • It insists that the user enters a userID.
      (Anonymous_NoUserID)
      • 

      
    • It insists that the user enters a password.
      (Anonymous_MustGiveEmail)
      • 

      
    • The password entered must be a valid email address, i.e.
      contain at least one '@' and a '.'.
      (Anonymous_VerifyEmail)
      • 

      
    • The userID must be one of anonymous guest www test
      welcome and comparison is not case
      sensitive. (Anonymous)
      • 

      
    • And the Email addresses entered in the passwd field are
      logged to the error log file.
      (Anonymous_LogEmail)
      • 
    
    

    
    Example
    <Directory "/var/www/html/private">
    AuthName "Use 'anonymous' & Email address for guest entry"
    AuthType Basic
    AuthBasicProvider file anon
    AuthUserFile "/path/to/your/.htpasswd"

    Anonymous Directive
    

    

    Description:Specifies userIDs that are allowed access without
password verification

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_anon
    

    
    
    A list of one or more 'magic' userIDs which are allowed
    access without password verification. The userIDs are space
    separated. It is possible to use the ' and " quotes to allow a
    space in a userID as well as the \ escape character.
    

    
    Please note that the comparison is
    case-IN-sensitive.
    
    It's strongly recommended that the magic username
    'anonymous' is always one of the allowed
    userIDs.
    

    
    Example:
    Anonymous anonymous "Not Registered" "I don't know"
    

    

    
    This would allow the user to enter without password
    verification by using the userIDs "anonymous",
    "AnonyMous", "Not Registered" and "I Don't Know".
    

    
    As of Apache 2.1 it is possible to specify the userID as
    "*". That allows any supplied userID to be
    accepted.

    Anonymous_LogEmail Directive
    

    

    Description:Sets whether the password entered will be logged in the
error log
    

    Syntax:Anonymous_LogEmail On|Off
    

    Default:Anonymous_LogEmail On
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_anon
    

    
    
    When set On, the default, the 'password' entered
    (which hopefully contains a sensible email address) is logged in
    the error log.

    Anonymous_MustGiveEmail Directive
    

    

    Description:Specifies whether blank passwords are allowed
    

    Syntax:Anonymous_MustGiveEmail On|Off
    

    Default:Anonymous_MustGiveEmail On
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_anon
    

    
    
    Specifies whether the user must specify an email address as
    the password. This prohibits blank passwords.

    Anonymous_NoUserID Directive
    

    

    Description:Sets whether the userID field may be empty
    

    Syntax:Anonymous_NoUserID On|Off
    

    Default:Anonymous_NoUserID Off
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_anon
    

    
    
    When set On, users can leave the userID (and
    perhaps the password field) empty. This can be very convenient for
    MS-Explorer users who can just hit return or click directly on the
    OK button; which seems a natural reaction.

    Anonymous_VerifyEmail Directive
    

    

    Description:Sets whether to check the password field for a correctly
formatted email address
    

    Syntax:Anonymous_VerifyEmail On|Off
    

    Default:Anonymous_VerifyEmail Off
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authn_anon
    

    
    
    When set On the 'password' entered is checked for
    at least one '@' and a '.' to encourage users to enter valid email
    addresses (see the above Anonymous_LogEmail).

    説明:URI をキーにしたコンテンツキャッシュストレージ管理
    

    ステータス:Extension
    

    モジュール識別子:cache_disk_module
    

    ソースファイル:mod_cache_disk.c
    

    概要
    

    
    mod_cache_disk はディスクを使用したストレージ
    管理機構を実装しています。主に
    mod_cache と組み合わせて使われます。
    

    
    コンテンツのキャッシュへの保存と取得は URI に基づいたキーが使われます。
    アクセス保護のかけられているコンテンツはキャッシュされません。
    

    
    キャッシュの大きさを最大レベルで維持するために
    htcacheclean を使うことができます。
    

    
    注:
    
      
    mod_cache_disk は
      mod_cache を必要とします

    ステータス:Extension
    

    モジュール:mod_cache_disk
    

    
    
    CacheDirLength ディレクティブはキャッシュ
    階層の各サブディレクトリの文字数を設定します。
    CacheDirLevels と組み合わせて設定することで、
    キャッシュ階層のおおよその構造を決めることができます。
    
    
    CacheDirLength が大きくて
    CacheDirLevels が小さい場合、
    比較的浅い階層になりますが、
    各階層のサブディレクトリの数は多くなります。
    

    
    
      
    CacheDirLevels*
      CacheDirLength の
      結果は 20 以内でなければなりません。

    CacheDirLevels ディレクティブ
    

    

    説明:キャッシュのサブディレクトリの深さの数
    

    構文:CacheDirLevels levels
    

    デフォルト:CacheDirLevels 2
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Extension
    

    モジュール:mod_cache_disk
    

    
    
    CacheDirLevels ディレクティブはキャッシュの
    サブディレクトリの深さを設定します。キャッシュデータは CacheRoot ディレクトリから
    このディレクトリの深さ分下のディレクトリに保存されます。
    
    
    CacheDirLevels が大きくて
    CacheDirLength が小さい場合、
    比較的深い階層になりますが、
    各階層のサブディレクトリの数は少なくなります。
    

    
    
      
    CacheDirLevels*
      CacheDirLength の
      結果は 20 以内でなければなりません。

    CacheMaxFileSize ディレクティブ
    

    

    説明:キャッシュに保管されるドキュメントの最大の (バイトでの) サイズ
    

    構文:CacheMaxFileSize bytes
    

    デフォルト:CacheMaxFileSize 1000000
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Extension
    

    モジュール:mod_cache_disk
    

    
    
    CacheMaxFileSize ディレクティブは、ドキュメントを
    キャッシュするかどうかを判定する、最大のサイズをバイト数で設定します。
    

    
    
      CacheMaxFileSize 64000

    ステータス:Extension
    

    モジュール:mod_cache_disk
    

    
    
    CacheMinFileSize ディレクティブは、ドキュメントを
    キャッシュするかどうかを判定する、最小のサイズをバイト数で設定します。
    

    
    
      CacheMinFileSize 64

    CacheReadSize ディレクティブ
    

    

    説明:The minimum size (in bytes) of the document to read and be cached before sending the data downstream
    

    構文:
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess

    CacheRoot ディレクティブ
    

    

    説明:キャッシュファイルが保管されるルートディレクトリ
    

    構文:CacheRoot directory
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Extension
    

    モジュール:mod_cache_disk
    

    
    
    CacheRoot ディレクティブはキャッシュファイルを
    保管するためのディスク上のディレクトリを指定します。mod_cache_disk モジュールが Apache サーバにロードされて
    いるか、組み込まれていれば、このディレクティブは必ず
    定義しなければなりません。
    CacheRoot の値を指定しなければ、
    設定ファイルの処理でエラーになります。CacheDirLevels ディレクティブと CacheDirLength ディレクティブが
    指定されたルートディレクトリ下のディレクトリ構成を定義します。
    

    
    
      CacheRoot c:/cacheroot

    Module Apache mod_ratelimit
    

    

    Langues Disponibles:  en  |

    Description:Limitation de la bande passante pour les clients
    

    Statut:Extension
    

    Identificateur de Module:ratelimit_module
    

    Fichier Source:mod_ratelimit.c
    

    Compatibilité:
    rate-initial-burst est disponible à partir de la version 2.4.24
    du serveur HTTP Apache. La limitation de bande passante pour les contenus
    mandatés ne fonctionne pas correctement jusqu'à la version 2.4.33.

    

    Sommaire
    



    Ce module fournit un filtre RATE_LIMIT pour limiter la
bande passante des clients. Cette contrainte s'applique à chaque réponse HTTP au
moment où elle est envoyée au client ; elle n'affecte pas les autres échanges
entre le client et le serveur. La variable d'environnement
rate-limit permet de spécifier, en kb/s, le débit de la
connexion à simuler.
    


    Optionnellement, il est possible, via la variable d'environnement
rate-initial-burst, de définir une quantité de données en
kOctets à transmettre à pleine vitesse avant de limiter la bande passante à la
valeur voulue.
    


    Exemple de configuration
    <Location "/downloads">
    SetOutputFilter RATE_LIMIT
    SetEnv rate-limit 400
    SetEnv rate-initial-burst 512
</Location>
    

    
Si la valeur affectée à rate-limit dépasse la valeur maximale à
affecter à un entier, la limitation de bande passante sera désactivée. Si la
valeur affectée à rate-limit-burst dépasse la valeur maximale à
affecter à un entier, la transmission du burst initial sans limitation de bande
passante sera désactivée.

mod_dumpio - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Apache Module mod_dumpio
    

    

    Available Languages:  en  |

    Description:Dumps all I/O to error log as desired.
    

    Status:Extension
    

    Module Identifier:dumpio_module
    

    Source File:mod_dumpio.c
    

    Summary
    

    
    mod_dumpio allows for the logging of
    all input received by Apache and/or all output sent by
    Apache to be logged (dumped) to the error.log file.
    
    

    
    The data logging is done right after SSL decoding (for
    input) and right before SSL encoding (for output). As can
    be expected, this can produce extreme volumes of data,
    and should only be used when debugging problems.

    Enabling dumpio Support
    
    

    
    To enable the module, it should be compiled and loaded
    in to your running Apache configuration. Logging can then
    be enabled or disabled separately for input and output via
    the below directives.  Additionally, mod_dumpio
    needs to be configured to LogLevel trace7:
    
    
    
    LogLevel dumpio:trace7

    Bu yönerge sunucuya başlatıldıktan sonra ağdan gelen istekleri kabul
      etmeden önce belirtilen dizine chroot(8) yapmasını söyler.
    

    
    Sunucuyu chroot altında çalıştırmanın basit bir işlem olmadığına ve
      özellikle CGI veya PHP gibi betikler çalıştırıyorsanız ek ayarlamalar
      yapmanız gerektiğine dikkat ediniz. Lütfen, bu özelliği kullanmaya
      çalışmadan önce chroot işlemleri hakkında gerektiği kadar bilgi sahibi

    Group yönergesi, sunucunun hangi grup altında
      isteklere yanıt vereceğini belirler. Bu yönergenin uygulanabilmesi için
      sunucunun root olarak çalıştırılmış olması gerekir.
      Sunucuyu root dışında bir kullanıcı başlattığı takdirde,
      sunucu belirtilen gruba geçemez ve kullanıcının kendi grubunda
      çalışmaya devam eder. unix-grubu şunlardan biri olabilir:
    

    
    
      
    Bir grup adı
    
      
    Gruba ismiyle başvurulur.

    Çalışan sunucu için özellikle yeni bir grup atamanız önerilir. Bazı
      sistem yöneticileri nobody grubunu kullanırlar fakat
      bu her zaman mümkün olmadığı gibi arzulanan da değildir.

      yönergelerini tanımlamakta kullanılan terimler açıklanmıştır.

    Açıklama
    


    Yönergenin kullanım amacının kısa bir açıklaması.
    

    top
    

    

    Sözdizimi
    

    
    Yönergenin bir yapılandırma dosyasında hangi söz dizimiyle
      görünebileceği belirtilir. Bu sözdizimi yönergeye özeldir ve ayrıntıları
      yönerge tanımında açıklanır. Genelde yönerge ismini aralarında boşluklar
      bırakılmış bir dizi argüman izler. Eğer argümanlardan biri kendi içinde
      boşluk içeriyorsa çift tırnak içine alınır. İsteğe bağlı argümanlar
      sözdiziminde köşeli ayraçların arasında gösterilmiştir. Birden fazla
      olası değeri olan argümanlarda değerler aralarına | karakteri konarak
      ayrılmıştır. Değerin yerine ismi belirtilen argümanlarda bu isimler
      eğik yazılırken, kendisi değer olan dizgeler öntanımlı yazıtipi
      ile gösterilmiştir. Değişik sayıda argüman alan yönergelerde bu durum son
      argümanı takibeden “...” ile belirtilmiştir.
    

    
    Yönergelerde kullanılan argüman türleri çok çeşitlidir. Çok
      kullanılanlardan bazıları aşağıda tanımlanmıştır.
    

    
    
      
    URL
    

      
    http://host.example.com/yol/yordam/dosya.html
        örneğindeki gibi protokol şeması ve konak ismini isteğe bağlı bir dosya
        yolunun izlediği, açılımı “Uniform Resource Locator” olan ve Türkçe’ye
        “Tektip Özkaynak Konumlayıcı” şeklinde çevrilebilecek adresleri
        betimler.
    

      
    URL-yolu
    

      
    /yol/yordam/dosya.html örneğindeki gibi bir
        url’nin parçası olarak protokol şeması ve konak ismini izleyen
        bir yol dizgesini betimler. url-yolu, bir dosya sisteminin kök
        dizinine göre değil, DocumentRoot
        ile belirtilen dizine göre bir dosya yolu betimler.
    

      
    dosya-yolu
    

      
    /usr/local/apache/htdocs/yol/yordam/dosya.html
        örneğindeki gibi yerel dosya sisteminin kök dizini ile başlayan bir
        dosya yolunu betimler. Aksi belirtilmedikçe, bir / ile başlamayan bir
        dosya-yolu ServerRoot ile
        belirtilen dizine göre ele alınır.
    

      
    dizin-yolu
    

      
    /usr/local/apache/htdocs/yol/yordam/ örneğindeki gibi
        kök dizin ile başlayan, yerel dosya sistemindeki bir dizin yolunu
        betimler.
    

      
    dosya-ismi
    

      
    dosya.html örneğindeki gibi dizin yolu içermeyen bir
        dosya ismini betimler.
    

      
    düzifd
    

      
    Bir Perl uyumlu düzenli ifade
        betimler. Yönerge tanımında düzifd ile eşleşenler argüman
        olarak ele alınır.
    

      
    uzantı
    

      
    Bu genelde, dosya-ismi’nin bir parçası olarak son noktadan
        sonraki kısmı betimler. Bununla birlikte, Apache çok sayıda nokta
        içeren dosya isimlerinde ilk noktadan sonrasını uzantı kabul
        eden çoklu dosya ismi uzantılarını da tanır. Örneğin, dosya-
        ismi olarak dosya.html.tr değeri iki uzantı içerir:
        .html ve .tr. Apache yönergelerinde
        uzantı’ları başında noktası olmaksızın da belirtebilirsiniz.
        Ayrıca, uzantı’lar harf büyüklüğüne de duyarlı değildir.
    

      
    MIME-türü
    

      
    Dosya biçiminin, text/html örneğindeki gibi aralarına
        bir / konulmuş asıl ve alt biçimler şeklinde açıklandığı yönteme göre
        belirtileceğini betimler.
    

      
    ortam-değişkeni
    

      
    Apache yapılandırma sürecinde tanımlanmış bir ortam değişkeninin ismini betimler. Daha
        ayrıntılı bilgi için ortam değişkenleri
        belgesine bakınız.
    
    
    

    top
    

    

    Öntanımlı
    

    
    Eğer yönerge öntanımlı bir değere sahipse o burada belirtilir (öntanımlı
      değer, yönergede kullanıcı tarafından belirtilmediği halde Apache
      tarafından belirtildiği varsayılarak işlem yapılan değerdir). Eğer
      öntanımlı bir değer yoksa bu bölümde bu durum “Yok” şeklinde
      belirtilir. Burada belirtilen öntanımlı değerin sunucu ile dağıtılan
      öntanımlı httpd.conf içindeki yönergede kullanılan değerle aynı olmasının
      gerekmediğine dikkat ediniz.
    

    top
    

    

    Bağlam
    

    
    Yönergenin sunucunun yapılandırma dosyalarının nerelerinde meşru kabul
      edildiği aşağıdaki değerlerin virgül ayraçlı bir listesi halinde burada
      belirtilir.
    

    
    
      
    sunucu geneli
    

      
    Yönergenin sunucunun (httpd.conf gibi) yapılandırma
        dosyalarında <VirtualHost> ve <Directory> bölümleri dışında
        her yerde kullanılabileceğini belirtir. Ayrıca, .htaccess
        dosyalarında bulunmasına da izin verilmez.
    

      
    sanal konak
    

      
    Yönergenin sunucunun yapılandırma dosyalarının sadece <VirtualHost> bölümlerinde
        kullanıldığında geçerli kabul edileceğini belirtir.
    

      
    dizin
    

      
    Yönergenin sunucunun yapılandırma dosyalarında sadece <Directory>, <Location>, <Files>, <If> ve <Proxy> bölümlerinde
        kullanıldığında geçerli kabul edileceğini belirtir. Bu bağlama konu
        sınırlamaların çerçevesi  Yapılandırma
        Bölümleri içinde çizilmiştir.
    

      
    .htaccess
    

      
    Bu bağlamda geçerli olacağı kabul edilen bir yönerge sadece dizin içi
        .htaccess dosyalarında görüldüğü zaman işleme sokulur.
        Üzerinde bir geçersizleştirme etkin kılınmışsa
        yönerge her şeye rağmen işleme sokulmayabilir.
    
    
    

    
    Yönergeye sadece tasarlandığı bağlam içinde izin verilir; başka
      bir yerde kullanmayı denerseniz ya sunucunun bu bağlamı doğru şekilde
      işlemesine engel olan ya da sunucunun tamamen işlevsiz kalmasına sebep
      olan  -- sunucu hiç başlatılamayabilir -- bir yapılandırma hatası
      alırsınız.
    

    
    Yönergenin geçerli olacağı konumlar, aslında, listelenen bağlamların
      tamamına mantıksal VEYA uygulanarak bulunur. Başka bir deyişle, bir
      yönergenin geçerli olacağı yerler "sunucu geneli, .htaccess"
      şeklinde belirtilmişse yönerge httpd.conf dosyasında ve
      .htaccess dosyalarında, <Directory> veya <VirtualHost> bölümleri haricinde her yerde
      kullanılabilir.
    

    top
    

    

    Geçersizleştirme
    

    
    Bir .htaccess dosyasında göründüğü takdirde yönerge
      işlenirken hangi yapılandırma geçersizleşirmesinin etkin olacağı burada
      belirtilir. Eğer yönerge bağlamının
      .htaccess dosyalarında görünmesine izin verilmiyorsa hiçbir
      bağlam listelenmez.
    

    
    Geçersizleştirmeler AllowOverride
      yönergesi tarafından etkinleştirilir ve belli bir bağlama ve alt
      seviyelerde başka AllowOverride
      yönergeleri ile değiştirilmedikçe tüm çocuklarına uygulanır. Yönergenin
      belgesinde ayrıca kullanılabilecek tüm olası geçersizleştirme isimleri
      belirtilir.
    

    top
    

    

    Durum
    

    
    Yönergenin Apache HTTP sunucusuna ne kadar sıkı bağlı olduğunu belirtir.
      Başka bir deyişle, yönergeye ve işlevselliğine erişim kazanmak için
      sunucuyu belli bir modül kümesiyle yeniden derlemek gerekip gerekmediği
      ile ilgili durumu belirtir. Bu özniteliğin olası değerleri şunlardır:
    

    
    
      
    Çekirdek
    

      
    Eğer bir yönerge “Çekirdek” durumuna sahip olarak listelenmişse bu,
        yönergenin Apache HTTP sunucusunun en iç kısımlarının bir parçası
        olduğu ve daima kullanılabilir olacağı anlamına gelir.
    

      
    MPM
    

      
    “MPM” durumuna sahip bir yönerge Çok Süreklilik
        Modülü tarafından sağlanır. Bu yönerge türü sadece ve sadece
        yönerge tanımının Modül satırında listelenmiş
        MPM’lerden birini kullanıyorsanız mevcut olacaktır.
    

      
    Temel
    

      
    “Temel” durumuna sahip bir yönerge, sunucuda öntanımlı derlenmiş
        standart Apache modüllerinden biri tarafından destekleniyor demektir.
        Bu nedenle sunucuyu derlemek için yapılandırırken yönergeyi içeren
        modülü yapılandırmadan özellikle kaldırmazsanız yönerge normal olarak
        kullanılabilir olacaktır.
    

      
    Eklenti
    

      
    “Eklenti” durumuna sahip bir yönerge, Apache sunucu kitinde bulunan
        ancak normalde sunucuyla birlikte derlenmeyen modüllerden biri
        tarafından sağlanır. Yönergeyi ve işlevselliğini etkin kılmak için
        sunucunun derleme öncesi paket yapılandırması sırasında modülün
        derleneceğini açıkça belirttikten sonra gerekirse sunucuyu yeniden
        derlemeniz gerekir.
    

      
    Deneysel
    

      
    “Deneysel” durumuna sahip bir yönerge, Apache sunucu kitinde bulunan
        modüllerden biri tarafından sağlanır ve modülün denenmesi tamamen sizin
        insiyatifinize bırakılır. Böyle bir yönerge her şeyiyle belgelenmiştir
        fakat gerektiği gibi desteklenmemiştir. Yönergeyi içeren modül
        öntanımlı olarak sunucuyla birlikte derlenebileceği gibi
        derlenmeyebilir de; bunun için yönergenin açıklandığı sayfanın başına
        ve kullanılabilirliği hakkında bilgi edinmek için yönergeyi içeren
        modüle bakın.
    
    
    

    top
    

    

    Modül
    

    
    Burada sadece yönergeyi tanımlayan kaynak modülün ismi yazılır.
    

    top
    

    

    Uyumluluk
    

    
    Eğer yönerge Apache’nin 2. sürüm dağıtımının özgün parçası değilse söz
      konusu sürüm burada belirtilir. Ayrıca, yönergenin kullanımı belli
      platformlarla sınırlıysa bunun ayrıntıları da burada belirtilir.

    Description:Group Authorization and Login using SQL
    

    Status:Extension
    

    Module Identifier:authz_dbd_module
    

    Source File:mod_authz_dbd.c
    

    Compatibility:Available in Apache 2.4 and later
    

    Summary
    

    
    This module provides authorization capabilities so that
       authenticated users can be allowed or denied access to portions
       of the web site by group membership.  Similar functionality is
       provided by mod_authz_groupfile and
       mod_authz_dbm, with the exception that
       this module queries a SQL database to determine whether a
       user is a member of a group.
    
    
    This module can also provide database-backed user login/logout
       capabilities.  These are likely to be of most value when used
       in conjunction with mod_authn_dbd.
    
    
    This module relies on mod_dbd to specify
       the backend database driver and connection parameters, and
       manage the database connections.
    

    


    top
    

    

    The Require Directives
    

    
    Apache's Require
    directives are used during the authorization phase to ensure that
    a user is allowed to access a resource.  mod_authz_dbd extends the
    authorization types with dbd-group, dbd-login and
    dbd-logout.
    

    
    Since v2.4.8, expressions are supported
    within the DBD require directives.
    


    Require dbd-group
    

    
    This directive specifies group membership that is required for the
    user to gain access.
    

    
    Require dbd-group team
AuthzDBDQuery "SELECT group FROM authz WHERE user = %s"
    





    Require dbd-login
    

    
    This directive specifies a query to be run indicating the user
    has logged in.
    

    
    Require dbd-login
AuthzDBDQuery "UPDATE authn SET login = 'true' WHERE user = %s"
    





    Require dbd-logout
    

    
    This directive specifies a query to be run indicating the user
    has logged out.
    

    
    Require dbd-logout
AuthzDBDQuery "UPDATE authn SET login = 'false' WHERE user = %s"
    





    top
    

    

    Database Login
    


    
In addition to the standard authorization function of checking group
membership, this module can also provide server-side user session
management via database-backed login/logout capabilities.
Specifically, it can update a user's session status in the database
whenever the user visits designated URLs (subject of course to users
supplying the necessary credentials).
    

    This works by defining two special
Require types:
Require dbd-login and Require dbd-logout.
For usage details, see the configuration example below.
    

    top
    

    

    Client Login integration
    


    Some administrators may wish to implement client-side session
management that works in concert with the server-side login/logout
capabilities offered by this module, for example, by setting or unsetting
an HTTP cookie or other such token when a user logs in or out.
    

    To support such integration, mod_authz_dbd exports an
optional hook that will be run whenever a user's status is updated in
the database.  Other session management modules can then use the hook
to implement functions that start and end client-side sessions.

    AuthzDBDLoginToReferer Directive
    

    

    Description:Determines whether to redirect the Client to the Referring
page on successful login or logout if a Referer request
header is present
    

    Syntax:AuthzDBDLoginToReferer On|Off
    

    Default:AuthzDBDLoginToReferer Off
    

    Context:directory
    

    Status:Extension
    

    Module:mod_authz_dbd
    

    
    
    In conjunction with Require dbd-login or
    Require dbd-logout, this provides the option to
    redirect the client back to the Referring page (the URL in
    the Referer HTTP request header, if present).
    When there is no Referer header,
    AuthzDBDLoginToReferer On will be ignored.

    AuthzDBDQuery Directive
    

    

    Description:Specify the SQL Query for the required operation
    

    Syntax:AuthzDBDQuery query
    

    Context:directory
    

    Status:Extension
    

    Module:mod_authz_dbd
    

    
    
    The AuthzDBDQuery specifies an SQL
    query to run.  The purpose of the query depends on the
    Require directive in
    effect.
    
    
      
    
    • When used with a Require dbd-group directive,
    it specifies a query to look up groups for the current user.  This is
    the standard functionality of other authorization modules such as
    mod_authz_groupfile and mod_authz_dbm.
    The first column value of each row returned by the query statement
    should be a string containing a group name.  Zero, one, or more rows
    may be returned.
    
      Require dbd-group
AuthzDBDQuery "SELECT group FROM groups WHERE user = %s"
      

    
      • 
    
    • When used with a Require dbd-login or
    Require dbd-logout directive, it will never deny access,
    but will instead execute a SQL statement designed to log the user
    in or out.  The user must already be authenticated with
    mod_authn_dbd.
    
      Require dbd-login
AuthzDBDQuery "UPDATE authn SET login = 'true' WHERE user = %s"
      

    
      • 
    
    
    
    In all cases, the user's ID will be passed as a single string
    parameter when the SQL query is executed.  It may be referenced within
    the query statement using a %s format specifier.
    


    

    top
    

    AuthzDBDRedirectQuery Directive
    

    

    Description:Specify a query to look up a login page for the user
    

    Syntax:AuthzDBDRedirectQuery query
    

    Context:directory
    

    Status:Extension
    

    Module:mod_authz_dbd
    

    
    
    Specifies an optional SQL query to use after successful login
    (or logout) to redirect the user to a URL, which may be
    specific to the user.  The user's ID will be passed as a single string
    parameter when the SQL query is executed.  It may be referenced within
    the query statement using a %s format specifier.
    
    
    AuthzDBDRedirectQuery "SELECT userpage FROM userpages WHERE user = %s"
    

    
    The first column value of the first row returned by the query
    statement should be a string containing a URL to which to redirect
    the client.  Subsequent rows will be ignored.  If no rows are returned,
    the client will not be redirected.
    
    
    Note that AuthzDBDLoginToReferer takes
    precedence if both are set.

    Sommaire
    

    
    Avertissement
    
      
    L'authentification à base de formulaire dépend des modules
      mod_session qui utilisent les cookies HTTP, et en
      tant que tels s'exposent à des attaques de type Cross Site
      Scripting, ou risquent de divulguer des informations à caractère
      privé aux clients. Assurez-vous que ces risques ont bien été pris
      en compte avant d'activer les sessions sur votre serveur.
    
    
    

    
    Ce module permet de restreindre l'accès en recherchant les
    utilisateurs dans les fournisseurs spécifiés à l'aide d'un
    formulaire de connexion HTML. Les formulaires HTML requièrent
    davantage de configuration que les méthodes d'authentification
    alternatives, mais ils peuvent s'avérer beaucoup plus conviviaux
    pour les utilisateurs.
    
    

    
    L'authentification HTTP de base est fournie par le module
    mod_auth_basic, et l'authentification HTTP à base
    de condensé par le module mod_auth_digest. Le
    module mod_auth_form doit être utilisé avec au
    moins un module d'authentification du style
    mod_authn_file et un module d'autorisation comme
    mod_authz_user.
    

    
    Lorsque l'utilisateur a été authentifié avec succès, ses
    informations de connexion sont stockés dans une session fournie par
    le module mod_session.
    
    


    


    top
    

    

    Configuration de base
    

      
    Pour protéger une URL particulière avec le module
      mod_auth_form, vous devez déterminer l'endroit où
      vous allez stocker votre session, ainsi que la méthode
      d'authentification. Dans cet exemple simple, les informations de
      connexion sont stockées dans une session à l'aide du module
      mod_session_cookie, et l'authentification utilise
      un fichier en s'appuyant sur le module
      mod_authn_file. Si l'authentification échoue,
      l'utilisateur dera redirigé vers la page du formulaire de
      connexion.
    

      
    Exemple simple
    <Location "/admin">
    AuthFormProvider file
    AuthUserFile "conf/passwd"
    AuthType form
    AuthName "/admin"
    AuthFormLoginRequiredLocation "http://example.com/login.html"

    Session On
    SessionCookieName session path=/

    Require valid-user
</Location>
    

    

      
    L'authentification mod_auth_form est activée
      en affectant la valeur form à la directive AuthType. Les directives
      AuthFormProvider et
      AuthUserFile
      spécifient que les noms d'utilisateurs et mots de passe seront
      vérifiés en utilisant le fichier choisi.
    

      
    Les directives Session et SessionCookieName créent une
      session chiffrée stockée dans un cookie HTTP au niveau
      du navigateur. Pour plus d'informations à propos des différentes
      options de configuration des sessions, reportez-vous à la
      documentation du module mod_session.
    

      
    Vous pouvez éventuellement ajouter une directive SessionCryptoPassphrase pour créer
      un cookie de session chiffré. Pour utiliser cette directive, le module
      mod_session_crypto doit avoir été préalablement chargé.
    

      
    Dans l'exemple simple ci-dessus, une URL a été protégée par
      mod_auth_form, mais on doit maintenant fournir
      à l'utilisateur un moyen d'entrer un nom et un mot de passe. À cet
      effet, on peut soit écrire une page de connexion indépendante
      dédiée, soit inclure le formulaire de connexion dans la page
      courante.
    
    
    top
    

    

    Page de connexion dédiée
    

      
    Le formulaire de connexion peut être contenu dans une page
      indépendante, ou être inclus dans la page courante. 
    

      
    Lorsque la connexion s'effectue à partir d'une page
      indépendante et si la tentative d'authentification échoue,
      l'utilisateur doit être redirigé vers un formulaire de connexion,
      créé à cet effet sur le site web, en utilisant la directive
      AuthFormLoginRequiredLocation.
      En général, la page de connexion contiendra un formulaire HTML
      demandant à l'utilisateur de fournir un nom et un mot de passe.
    

      
    Exemple de formulaire de connexion
    <form method="POST" action="/dologin.html">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
</form>
    

    

      
    La partie où s'effectue la connexion proprement dite est
      traitée par le gestionnaire form-login-handler.
      L'action de ce formulaire doit pointer vers ce gestionnaire, ce
      que l'on configure dans Apache httpd comme suit :
    

      
    Exemple de configuration du gestionnaire de
      formulaire de connexion
    <Location "/dologin.html">
    SetHandler form-login-handler
    AuthFormLoginRequiredLocation "http://example.com/login.html"
    AuthFormLoginSuccessLocation "http://example.com/admin/index.html"
    AuthFormProvider file
    AuthUserFile "conf/passwd"
    AuthType form
    AuthName /admin
    Session On
    SessionCookieName session path=/
    SessionCryptoPassphrase secret
</Location>
    

    

      
    L'URL spécifiée par la directive
      AuthFormLoginRequiredLocation
      référencera en général une page expliquant à l'utilisateur que sa
      tentative de connexion a échoué, et qu'il doit la renouveler. La
      directive AuthFormLoginSuccessLocation
      spécifie l'URL vers laquelle l'utilisateur doit être redirigé s'il
      s'est authentifié avec succès.
    

      
    Alternativement, l'URL vers laquelle doit être redirigé
      l'utilisateur s'il s'est authentifié avec succès peut être
      intégrée dans le formulaire de connexion, comme dans l'exemple
      ci-dessous. Il en découle que le même gestionnaire
      form-login-handler pourra être utilisé pour différentes
      zones du site web.
    

      
    Exemple de formulaire d'authentification multizone
    <form method="POST" action="/dologin.html">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
  <input type="hidden" name="httpd_location" value="http://example.com/success.html" />
</form>
    

    

    
    top
    

    

    Connexion à la volée
    

      
    Avertissement
    
        
    Il existe un risque, dans certaines circonstances, que le
	formulaire de connexion configuré pour une connexion à la volée
	soit soumis plusieurs fois, révélant de ce fait les paramètres
	de connexion à l'application sous-jacente. L'administrateur doit
	s'assurer que cette dernière est correctement sécurisée afin
	d'éviter les éventuels abus. En cas de doute, utilisez une page
	de connexion indépendante dédiée.
    
      
    

      
    Comme alternative à la page de connexion dédiée pour un site
      web, il est possible de configurer mod_auth_form
      pour authentifier les utilisateurs à la volée, sans les rediriger
      vers une autre page, ce qui permet de conserver l'état de la page
      courante au cours de la tentative de connexion. Ceci peut s'avérer
      utile dans le cas d'une session limitée dans le temps, si le délai
      de la session a expiré pendant la requête de l'utilisateur. Ce
      dernier peut alors se réauthentifier à la même place, et
      poursuivre son activité à partir du point où il en était resté.
    

      
    Si un utilisateur non authentifié tente d'accéder à une page
      protégée par mod_auth_form, et si ce dernier
      n'est pas configuré avec une directive AuthFormLoginRequiredLocation,
      un code de statut HTTP_UNAUTHORIZED est renvoyé vers le
      navigateur, indiquant à l'utilisateur qu'il n'est pas autorisé à
      accéder à cette page.
    

      
    Pour configurer l'authentification à la volée, l'administrateur
      remplace le message d'erreur renvoyé par le code de statut
      HTTP_UNAUTHORIZED par un message d'erreur personnalisé
      contenant le formulaire de connexion comme suit :
    

      
    Exemple simple d'authentification à la volée
    AuthFormProvider file
ErrorDocument 401 "/login.shtml"
AuthUserFile "conf/passwd"
AuthType form
AuthName realm
AuthFormLoginRequiredLocation "http://example.com/login.html"
Session On
SessionCookieName session path=/
    

    

      
    La page du message d'erreur doit contenir un formulaire de
      connexion dont la propriété action est vide, comme dans l'exemple
      ci-dessous. Ceci a pour effet de soumettre le formulaire à l'URL
      protégée originale, cette dernière n'ayant pas besoin d'être
      connue de la page en cours.
    

      
    Exemple de formulaire de connexion à la volée
    <form method="POST" action="">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
</form>
    

    

      
    Lorsque l'utilisateur final a entré ses informations de
      connexion, le formulaire effectue une requête HTTP POST pour l'URL
      originale protégée par mot de passe.
      mod_auth_form va alors intercepter cette requête
      POST, et dans le cas où des champs HTML Utilisateur et Mot de
      passe corrects sont présents, l'utilisateur sera connecté, et
      l'URL originale protégée par mot de passe lui sera retournée en
      tant que requête GET.

    Connexion à la volée avec
    conservation du contenu
    

      
    Il existe une limite à la technique de connexion à la volée
      décrite ci-dessus ; si un formulaire HTML POST entraîne une
      demande d'authentification ou de réauthentification, le contenu du
      formulaire original envoyé par le navigateur sera perdu. Cela peut
      s'avérer plus ou moins gênant pour l'utilisateur final selon la
      fonction du site web.
    

      
    Comme solution à ce problème, mod_auth_form
      permet d'intégrer la méthode et le contenu de la requête originale
      dans le formulaire de connexion. Si l'authentification réussit,
      Apache httpd pourra refaire une tentative avec la méthode et le contenu
      originaux, tout en conservant l'état de la requête originale.
    

      
    Pour mettre en oeuvre la conservation du contenu, vous devez
      ajouter trois champs supplémentaires au formulaire de connexion
      comme dans l'exemple suivant :
    

      
    Exemple de formulaire avec conservation du
      contenu
    <form method="POST" action="">
  Username: <input type="text" name="httpd_username" value="" />
  Password: <input type="password" name="httpd_password" value="" />
  <input type="submit" name="login" value="Login" />
  
      <input type="hidden" name="httpd_method" value="POST" />
  <input type="hidden" name="httpd_mimetype" value="application/x-www-form-urlencoded" />
  <input type="hidden" name="httpd_body" value="name1=value1&name2=value2" />
    
</form>
    

    

      
    La manière dont la méthode, le type MIME et le contenu de la
      requête originale seront intégrés dans le formulaire de connexion
      vont dépendre de la plate-forme et de la technologie utilisées au
      sein du site web.
      
    

      
    Une option consiste à utiliser le module
      mod_include en association avec la directive
      KeptBodySize, ainsi
      qu'un script CGI adapté pour intégrer les variables dans le
      formulaire.
    

      
    Une autre option consiste à présenter le formulaire de
      connexion en utilisant un script CGI ou une autre technologie
      dynamique.
    

      
    Exemple avec script CGI
            AuthFormProvider file
        ErrorDocument 401 "/cgi-bin/login.cgi"
        ...

    Déconnexion
    

      
    Pour permettre à un utilisateur de se déconnecter d'une session
      particulière, vous devez configurer une page pour qu'elle soit
      traitée par le gestionnaire form-logout-handler. Tout
      accès à cette URL va entraîner la suppression de l'Utilisateur et
      du Mot de passe de la session courante, ce qui aura pour effet de
      déconnecter l'utilisateur.
    

      
    Vous pouvez spécifier une URL vers laquelle le navigateur sera
      redirigé en cas de déconnection réussie, en définissant la
      directive AuthFormLogoutLocation. Cette
      URL devra expliquer à l'utilisateur qu'il a été déconnecté, et lui
      donner la possibilité de se connecter à nouveau.
    

      
    Exemple simple de configuration de la
      déconnexion
    SetHandler form-logout-handler
AuthName realm
AuthFormLogoutLocation "http://example.com/loggedout.html"
Session On
SessionCookieName session path=/
    

    

      
    Notez que la déconnexion d'un utilisateur ne supprime pas la
      session ; elle supprime seulement l'utilisateur et le mot de passe
      de la session. Si la session qui en résulte est vide, elle sera
      probablement supprimée, mais ce n'est pas garanti. Si vous voulez
      être sûr que la session sera supprimée, affectez une valeur faible
      à la directive SessionMaxAge, par exemple 1
      (affecter à cette directive la valeur zéro signifie une session
      sans limite d'âge).
      
    

      
    Exemple simple avec durée de validité de session
      limitée
    SetHandler form-logout-handler
AuthFormLogoutLocation "http://example.com/loggedout.html"
Session On
SessionMaxAge 1
SessionCookieName session path=/
    

    

    
    top
    

    

    Noms d'utilisateurs et mots de
    passe
    
    
    Notez que la soumission d'un formulaire implique l'encodage URL
    (URLEncoding) des données du formulaire, ici le nom d'utilisateur et
    le mot de passe. Vous devez donc choisir des noms d'utilisateurs et
    mots de passe qui ne contiennent pas de caractères susceptibles
    d'être encodés URL lors de la soumission du formulaire, sous peine
    d'obtenir des résultats inattendus.

    Normalement, chacun des modules d'autorisation spécifiés par la
    directive AuthFormProvider va tenter de
    vérifier l'identité de l'utilisateur, et si ce dernier n'est trouvé
    dans aucun fournisseur, l'accès sera refusé. En définissant
    explicitement la directive
    AuthFormAuthoritative à Off on
    confie les processus d'authentification et d'autorisation à des
    modules ne s'appuyant pas sur des fournisseurs, si aucun
    identifiant utilisateur ou aucune règle ne
    correspond à l'identifiant utilisateur fourni. Ceci ne peut s'avérer
    nécessaire que si l'on combine mod_auth_form avec
    des modules tiers qui ne se configurent pas avec la directive
    AuthFormProvider.
    Lorsqu'on utilise de tels modules, la chronologie du processus est
    déterminée dans leur code source, et n'est pas configurable.

    Ce module fournit le support d'une interface de session pour
    chaque utilisateur au niveau du serveur global. Les sessions
    permettent de transmettre diverses informations  : l'utilisateur
    est-il connecté ou non, ou toute autre information qui doit être
    conservée d'une requête à l'autre.
    

    
    Les sessions peuvent être stockées sur le serveur, ou au niveau
    du navigateur. Les sessions peuvent également être chiffrées pour une
    sécurité accrue. Ces fonctionnalités sont réparties entre différents
    modules complémentaires de mod_session :
    mod_session_crypto,
    mod_session_cookie et
    mod_session_dbd. Chargez les modules appropriés
    en fonction des besoins du serveur (soit statiquement à la
    compilation, soit dynamiquement via la directive LoadModule).
    

    
    Les sessions peuvent être manipulées par d'autres modules qui
    dépendent de la session, ou la session peut être lue et écrite dans
    des variables d'environnement et des en-têtes HTTP, selon les
    besoins.

    Qu'est-ce qu'une session ?
    
      
    Au coeur de l'interface de session se trouve une table de
      paires clé/valeur qui sont accessibles d'une requête du navigateur
      à l'autre. Les valeurs de clés peuvent se voir affecter toute chaîne
      de caractères valide, en fonction des besoins de l'application qui
      fait usage de la session.
    

      
    Une "session" est une chaîne
      application/x-www-form-urlencoded qui contient la
      paire clé/valeur définie par la spécification HTML.
    

      
    Selon les souhaits de l'administrateur, la session peut être
      chiffrée et codée en base64 avant d'être soumise au dispositif de
      stockage.
    

    
    top
    

    

    Qui peut utiliser une session
    ?
    
      
    L'interface de session a été conçue à l'origine pour être
      utilisée par d'autres modules du serveur comme
      mod_auth_form ; les applications à base de
      programmes CGI peuvent cependant se voir accorder l'accès au
      contenu d'une session via la variable d'environnement
      HTTP_SESSION. Il est possible de modifier et/ou de mettre à jour
      une session en insérant un en-tête de réponse HTTP contenant les
      nouveaux paramètres de session.
    

    
    top
    

    

    Stockage des sessions sur le
    serveur
    
      
    Apache peut être configuré pour stocker les sessions
      utilisateurs sur un serveur particulier ou un groupe de serveurs.
      Cette fonctionnalité est similaire aux sessions disponibles sur
      les serveurs d'applications courants.
    

      
    Selon la configuration, les sessions sont suivies à
      partir d'un identifiant de session stocké dans un cookie, ou
      extraites de la chaîne de paramètres de l'URL, comme dans les
      requêtes GET courantes.
    

      
    Comme le contenu de la session est stocké exclusivement sur le
      serveur, il est nécessaire de préserver la confidentialité de ce
      contenu. Ceci a des implications en matière de performance et de
      consommation de ressources lorsqu'un grand nombre de sessions est
      stocké, ou lorsqu'un grand nombre de serveurs doivent se partager
      les sessions entre eux.
    

      
    Le module mod_session_dbd permet de stocker
      les sessions utilisateurs dans une base de données SQL via le
      module mod_dbd.
    

    
    top
    

    

    Stockage des sessions au niveau
    du navigateur
    
      
    Dans les environnements à haut trafic où le stockage d'une
      session sur un serveur consomme trop
      de ressources, il est possible de stocker le contenu de la session
      dans un cookie au niveau du navigateur client.
    

      
    Ceci a pour avantage de ne nécessiter qu'une quantité minimale de
      ressources sur le serveur pour suivre les sessions, et évite à
      plusieurs serveurs parmi une forêt de serveurs de devoir partager
      les informations de session.
    

      
    Le contenu de la session est cependant présenté au client, avec
      pour conséquence un risque de perte de confidentialité. Le module
      mod_session_crypto peut être configuré pour
      chiffrer le contenu de la session avant qu'elle soit stockée au
      niveau du client.
    

      
    Le module mod_session_cookie permet de stocker
      les sessions au niveau du navigateur dans un cookie HTTP.
    

    
    top
    

    

    Exemples simples
    

      
    La création d'une session consiste simplement à ouvrir la
      session, et à décider de l'endroit où elle doit être stockée. Dans
      l'exemple suivant, la session sera stockée au niveau du
      navigateur, dans un cookie nommé session.
    

      
    Session stockée au niveau du navigateur
    Session On
SessionCookieName session path=/
    

    

      
    Une session est inutile s'il n'est pas possible d'y lire
      ou d'y écrire. L'exemple suivant montre comment des valeurs
      peuvent être injectées dans une session à l'aide d'un en-tête de
      réponse HTTP prédéterminé nommé
      X-Replace-Session.
    

      
    Ecriture dans une session
    Session On
SessionCookieName session path=/
SessionHeader X-Replace-Session
    

    

      
    L'en-tête doit contenir des paires clé/valeur sous le même
      format que celui de la chaîne d'argument d'une URL, comme dans
      l'exemple suivant. Donner pour valeur à une clé la chaîne vide a
      pour effet de supprimer la clé de la session.
    

      
    Script CGI pour écrire dans une session
    #!/bin/bash
echo "Content-Type: text/plain"
echo "X-Replace-Session: key1=foo&key2=&key3=bar"
echo
env
    

    

      
    Selon la configuration, les informations de la session peuvent
      être extraites de la variable d'environnement HTTP_SESSION. Par
      défaut la session est privée, et cette fonctionnalité doit donc
      être explicitement activée via la directive SessionEnv.
    

      
    Lecture depuis une session
    Session On
SessionEnv On
SessionCookieName session path=/
SessionHeader X-Replace-Session
    

    

      
    Une fois la lecture effectuée, la variable CGI
      HTTP_SESSION doit contenir la valeur
      clé1=foo&clé3=bar.
    

    
    top
    

    

    Confidentialité des
    sessions
    

      
    En utilisant la fonctionnalité de votre navigateur "Afficher
      les cookies", vous pouvez voir une réprésentation de la session
      sous forme de texte en clair. Ceci peut poser problème si le
      contenu de la session doit être dissimulé à l'utilisateur final,
      ou si un tiers accède sans autorisation aux informations de
      session.
    

      
    À ce titre, le contenu de la session peut être chiffré à l'aide
      du module mod_session_crypto avant d'être stocké
      au niveau du navigateur.
    

      
    Session chiffrée avant stockage au niveau du
      navigateur
    Session On
SessionCryptoPassphrase secret
SessionCookieName session path=/
    

    

      
    La session sera automatiquement déchiffrée à la lecture, et
      rechiffrée par Apache lors de la sauvegarde, si bien que
      l'application sous-jacente qui utilise la session n'a pas à se
      préoccuper de savoir si un chiffrement a été mis en oeuvre ou
      non.
    

      
    Les sessions stockées sur le serveur plutôt qu'au niveau du
      navigateur peuvent aussi être chiffrées, préservant par là-même la
      confidentialité lorsque des informations sensibles sont partagées
      entre les serveurs web d'une forêt de serveurs à l'aide du module
      mod_session_dbd.
    

    
    top
    

    

    Confidentialité du cookie
    

      
    Le mécanisme de cookie HTTP offre aussi des fonctionnalités
      quant à la confidentialité, comme la possibilité de
      restreindre le transport du cookie aux pages protégées par SSL
      seulement, ou l'interdiction pour les scripts java qui
      s'exécutent au niveau du navigateur d'obtenir l'accès au contenu
      du cookie.
    

      
    Avertissement
    
      
    Certaines fonctionnalités de confidentialité du cookie HTTP ne
      sont pas standardisées, ou ne sont pas toujours implémentées au
      niveau du navigateur. Les modules de session vous permettent de
      définir les paramètres du cookie, mais il n'est pas garanti que la
      confidentialité sera respectée par le navigateur. Si la sécurité
      est la principale préoccupation, chiffrez le contenu de la session
      avec le module mod_session_crypto, ou stockez la
      session sur le serveur avec le module
      mod_session_dbd.
    
      
    

      
    Les paramètres standards du cookie peuvent être spécifiés après
      le nom du cookie comme dans l'exemple suivant :
    

      
    Définition des paramètres du cookie
    Session On
SessionCryptoPassphrase secret
SessionCookieName session path=/private;domain=example.com;httponly;secure;
    

    

      
    Dans les cas où le serveur Apache sert de frontal pour des
      serveurs d'arrière-plan, il est possible de supprimer les cookies
      de session des en-têtes HTTP entrants à l'aide de la directive
      SessionCookieRemove. Ceci
      permet d'empêcher les serveurs d'arrière-plan d'accéder au contenu
      des cookies de session.
      
    

    
    top
    

    

    Support des sessions pour
    l'authentification
    

      
    Comme il est possible de le faire avec de nombreux serveurs
      d'applications, les modules d'authentification peuvent utiliser
      une session pour stocker le nom d'utilisateur et le mot de passe
      après connexion. Le module mod_auth_form par
      exemple, sauvegarde les nom de connexion et mot de passe de
      l'utilisateur dans une session.
    

      
    Authentification à base de formulaire
    Session On
SessionCryptoPassphrase secret
SessionCookieName session path=/
AuthFormProvider file
AuthUserFile "conf/passwd"
AuthType form
AuthName "realm"
#...
    

    

      
    Pour la documentation et des exemples complets, voir le module
      mod_auth_form.
    

    
    top
    

    

    Intégration des sessions avec les
    applications externes
    

      
    Pour que les sessions soient utiles, leur contenu doit être
      accessible aux applications externes, et ces dernières doivent
      elles-mêmes être capables d'écrire une session.
    

      
    L'exemple type est une application qui modifie le mot de passe
      d'un utilisateur défini par mod_auth_form. Cette
      application doit pouvoir extraire les nom d'utilisateur et mot de
      passe courants de la session, effectuer les modifications
      demandées, puis écrire le nouveau mot de passe dans la session,
      afin que la transition vers le nouveau mot de passe soit
      transparente.
    

      
    Un autre exemple met en jeu une application qui enregistre un
      nouvel utilisateur pour la première fois. Une fois
      l'enregistrement terminé, le nom d'utilisateur et le mot de passe
      sont écrits dans la session, fournissant là aussi une transition
      transparente.
    

      
    
      
    Modules Apache
    
      
    Selon les besoins, les modules du serveur peuvent utiliser
      l'API mod_session.h pour lire et écrire dans les
      sessions. Les modules tels que mod_auth_form
      utilisent ce mécanisme.
      
    

      
    Programmes CGI et langages de script
    
      
    Les applications qui s'exécutent au sein du serveur web
      peuvent éventuellement extraire la valeur de la session de la
      variable d'environnement HTTP_SESSION. La session
      doit être codée sous la forme d'une chaîne
      application/x-www-form-urlencoded selon les
      préconisations de la specification HTML. Cette
      variable d'environnement est définie via la directive SessionEnv. Un script peut écrire
      dans la session en renvoyant un en-tête de réponse
      application/x-www-form-urlencoded dont le nom est
      défini via la directive SessionHeader. Dans les deux cas,
      tout chiffrement ou déchiffrement, ainsi que la lecture ou
      l'écriture de ou vers la session à partir du mécanisme de stockage
      choisi sont gérés par le module mod_session et la
      configuration correspondante.
      
    

      
    Applications situées derrière mod_proxy
    
      
    Si la directive SessionHeader est utilisée pour
      définir un en-tête de requête HTTP, la session codée sous la forme
      d'une chaîne application/x-www-form-urlencoded
      sera accessible pour l'application. Si ce même en-tête est fourni
      dans la réponse, sa valeur sera utilisée pour remplacer la
      session. Comme précédemment, tout chiffrement ou déchiffrement,
      ainsi que la lecture ou
      l'écriture de ou vers la session à partir du mécanisme de stockage
      choisi sont gérés par le module mod_session et la
      configuration correspondante.
    

      
    Applications indépendantes
    
      
    Les applications peuvent choisir de manipuler la session en
      s'affranchissant du contrôle du serveur HTTP Apache. Dans ce cas,
      c'est l'application qui doit prendre en charge la lecture de la
      session depuis le mécanisme de stockage choisi, son déchiffrement,
      sa mise à jour, son chiffrement et sa réécriture vers le mécanisme
      de stockage choisi de manière appropriée.

    La chaîne est écrite sous le même format que celui de la chaîne
    d'arguments d'une URL, comme dans l'exemple suivant :

    ciblant de manière plus précise l'espace d'URL pour lequel une
    session devra être maintenue. Par défaut, toutes les URLs du
    contexte ou du conteneur courant sont incluses dans la session. La
    directive SessionExclude
    l'emporte sur la directive SessionInclude.
    

    
    Avertissement
    
    
    Cette directive a un comportement similaire à celui de l'attribut
    chemin des cookies HTTP, mais ne doit pas être confondue
    avec cet attribut. En effet, cette directive ne définit pas
    l'attribut chemin, qui doit être configuré

    Module:mod_session
    

    Compatibilité:Disponible à partir de la version 2.4.41 du serveur HTTP Apache
    

    
    
    La directive SessionExpiryUpdateInterval
    permet d'éviter le coût de l'écriture d'une session pour chaque
    requête en n'effectuant cette mise à jour que lorsque la date
    d'expiration a changé. Ceci permet d'améliorer les performances d'un
    site web ou de réduire la charge d'une base de données lorsqu'on
    utilise mod_session_dbd. La session est
    systématiquement mise à jour si les données stockées dans la session
    ont été modifiées ou si la durée d'expiration a été modifiée d'une
    durée supérieure à l'intervalle spécifié.
    

    
    Définir l'intervalle à 0 désactive cette directive, et
    l'expiration de la session sera alors rafraîchie pour chaque requête.
    

    
    Cette directive n'a d'effet que si on l'utilise en combinaison
    avec la directive SessionMaxAge qui active
    l'expiration des sessions. Les sessions sans date d'expiration ne
    sont écrites que lorsque les données qu'elles renferment ont été
    modifiées.
    

    
    Avertissement
    
    
    Comme l'expiration de la session n'est pas systématiquement
    rafraîchie à chaque requête, une session peut arriver à expiration
    plus tôt d'un nombre de secondes spécifié dans le paramètre
    interval. Définir un petit intervalle est en général
    assez sur, mais en revenche n'a qu'un effet minime sur la prise en
    compte des durées d'expiration.

    réinitialisée et la session peut continuer d'exister. Si la durée
    d'une session dépasse cette limite sans qu'une requête au serveur ne
    vienne la rafraîchir, la session va passer hors délai et sera
    supprimée. Lorsqu'une session est utilisée pour stocker les
    informations de connexion d'un utilisateur, ceci aura pour effet de
    le déconnecter automatiquement après le délai spécifié.
    

    
    Donner à cette directive la valeur 0 empêche l'expiration de la
    session.

    Sommaire
    

    
    Ce module a été conçu pour être utilisé dans les suites de tests
    et les grands réseaux qui doivent prendre en compte différentes
    versions de httpd et différentes configurations. Il fournit un
    nouveau conteneur -- <IfVersion>, qui apporte une grande
    souplesse dans la vérification de version en permettant une
    comparaison numérique et l'utilisation d'expressions
    rationnelles.
    

    
    Exemples
    <IfVersion 2.4.2>
    # la version actuelle de httpd est exactement 2.4.2
</IfVersion>

    Directive <IfVersion>
    

    

    Description:Contient des portions de configuration dépendantes de la
version
    

    Syntaxe:<IfVersion [[!]opérateur] version> ...
</IfVersion>
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess

    Statut:Extension
    

    Module:mod_version
    

    
    
    La section <IfVersion>
    rassemble des directives de configuration qui ne sont exécutées que
    si la version de httpd satisfait aux critères spécifiés. Pour une
    comparaison normale (numérique), l'argument version doit
    être spécifié sous le format
    majeur[.mineur[.patch]],
    comme par exemple 2.1.0 ou 2.2.
    mineur et patch sont optionnels. Si ces
    numéros sont absents, il se voient affectée implicitement la valeur
    0. Les opérateurs numériques suivants sont autorisés
    :
    

    
    opérateurdescription
    

    = ou ==
        La version de httpd est égale à la valeur
	spécifiée
    

    >
        La version de httpd est supérieure à la valeur
	spécifiée
    

    >=
        La version de httpd est supérieure ou égale à la valeur
	spécifiée
    

    <
        La version de httpd est inférieure à la valeur
	spécifiée
    

    <=
        La version de httpd est inférieure ou égale à la valeur
	spécifiée
    

    

    
    Exemple
    <IfVersion >= 2.3>
    # la condition n'est satisfaite que pour les versions de httpd
	# supérieures ou égales à 2.3
</IfVersion>
    

    

    
    En plus d'une comparaison numérique, il est possible de comparer
    la version de httpd avec une expression
    rationnelle. Il existe deux méthodes pour spécifier cette
    dernière :
    

    
    opérateurdescription
    

    = ou ==
        version est de la forme
            /regex/
    

    ~
        version est de la forme
            regex
    

    

    
    Exemple
    <IfVersion = /^2.4.[01234]$/>
    # exemple de contournement pour les versions boguées
</IfVersion>
    

    

    
    Pour inverser la condition, tous les opérateurs peuvent être
    préfixés par un point d'exclamation (!) :
    

    
    <IfVersion !~ ^2.4.[01234]$>
    # pas pour ces versions
</IfVersion>
    

    

    
    Si opérateur est absent, sa valeur implicite est
    =.

    Sommaire
    

    
    Le module mod_socache_memcache est un fournisseur de cache
    d'objets partagés qui permet la création et l'accès à un cache
    maintenu par le système de mise en cache d'objets en mémoire
    distribuée à hautes performances memcached.
    
    

    
    Cette méthode "create" du fournisseur de cache d'objets partagés
    requiert une liste de spécifications hôte/port en cache mémoire
    séparées par des virgules. Si vous utilisez ce fournisseur
    dans la configuration d'autres modules (comme
    SSLSessionCache), vous devez
    fournir la liste des serveurs sous la forme du paramètre optionnel
    "arg".
    

     
    SSLSessionCache memcache:memcache.example.com:12345,memcache2.example.com:12345
    


    
    Vous trouverez des détails à propos des autres fournisseurs de
    cache d'objets partagés ici.

    Module:mod_socache_memcache
    

    Compatibilité:Disponible à partir de la version 2.4.17 du serveur HTTP
Apache.
    

    

    
    Définit la durée pendant laquelle les connexions
    inactives avec le(s) serveur(s) memcache seront conservées
    (plateformes threadées seulement).
    
    
    
    Les valeurs valides de la directive
    MemcacheConnTTL sont des durées d'une heure
    maximum. La valeur 0 signifie une absence de péremption
    

    
    L'unité par défaut pour ce délai est la seconde, mais vous
    pouvez ajouter un suffixe pour spécifier une unité différente ; ms
    pour milliseconde, s pour seconde, min pour minute et h pour heure..
    
    

    
    Dans les versions antérieures à 2.4.17, ce délai était codé en
    dur et sa valeur était 600 microsecondes. La valeur la plus proche
    de cette ancienne valeur pour la directive
    MemcacheConnTTL est donc 1ms.
    

    
    # Définition d'un délai de 10 minutes
MemcacheConnTTL 10min
# Définition d'un délai de 60 secondes
MemcacheConnTTL 60

    Description:Server-side imagemap processing
    

    Status:Base
    

    Module Identifier:imagemap_module
    

    Source File:mod_imagemap.c
    

    Summary
    

    
    This module processes .map files, thereby
    replacing the functionality of the imagemap CGI
    program. Any directory or document type configured to use the
    handler imap-file (using either
    AddHandler or
    SetHandler)
    will be processed by this module.
    

    
    The following directive will activate files ending with
    .map as imagemap files:
    

    
    AddHandler imap-file map
    


    
    Note that the following is still supported:
    

    
    AddType application/x-httpd-imap map
    


    
    However, we are trying to phase out "magic MIME types" so we
    are deprecating this method.

    New Features
    

    
    The imagemap module adds some new features that were not
    possible with previously distributed imagemap programs.
    

    
      
      
    • URL references relative to the Referer: information.
      • 

      
    • Default <base> assignment through a new map
      directive base.
      • 

      
    • No need for imagemap.conf file.
      • 

      
    • Point references.
      • 

      
    • Configurable generation of imagemap menus.
      • 
    
    

    top
    

    

    Imagemap File
    

    
    The lines in the imagemap files can have one of several
    formats:
    

    
    
      directive value [x,y ...]
    
      directive value "Menu text" [x,y
      ...]
    
      directive value x,y ... "Menu text"
    
    

    
    The directive is one of base,
    default, poly, circle,
    rect, or point. The value is an
    absolute or relative URL, or one of the special values listed
    below. The coordinates are x,y
    pairs separated by whitespace. The quoted text is used as the text of
    the link if a imagemap menu is generated. Lines beginning with '#' are
    comments.
    

    
    Imagemap File Directives
    
      
    There are six directives allowed in the imagemap file. The
      directives can come in any order, but are processed in the
      order they are found in the imagemap file.
    

      
    
      
    base Directive
    

      
    Has the effect of <base href="value">
      . The non-absolute URLs of the map-file are taken relative
      to this value. The base directive overrides
      ImapBase as set in a
      .htaccess file or in the server configuration files.
      In the absence of an ImapBase configuration
      directive, base defaults to
      http://server_name/.
    
      
    base_uri is synonymous with base.
      Note that a trailing slash on the URL is significant.
    

      
    default Directive
    

      
    The action taken if the coordinates given do not fit any
      of the poly, circle or
      rect directives, and there are no
      point directives. Defaults to nocontent
      in the absence of an ImapDefault configuration setting, causing a status
      code of 204 No Content to be returned. The client
      should keep the same page displayed.
    

      
    poly Directive
    

      
    Takes three to one-hundred points, and is obeyed if the
      user selected coordinates fall within the polygon defined by
      these points.
    

      
    circle
    

      
    Takes the center coordinates of a circle and a point on
      the circle. Is obeyed if the user selected point is with the
      circle.
    

      
    rect Directive
    

      
    Takes the coordinates of two opposing corners of a
      rectangle. Obeyed if the point selected is within this
      rectangle.
    

      
    point Directive
    

      
    Takes a single point. The point directive closest to the
      user selected point is obeyed if no other directives are
      satisfied. Note that default will not be
      followed if a point directive is present and
      valid coordinates are given.
    
      
    
    

    
    Values
    

      
    The values for each of the directives can be any of the
      following:
    

      
    
      
    a URL
    

      
    The URL can be relative or absolute URL. Relative URLs
      can contain '..' syntax and will be resolved relative to the
      base value.
    
      
    base itself will not be resolved according to the
      current value. A statement base mailto: will
      work properly, though.
    

      
    map
    

      
    Equivalent to the URL of the imagemap file itself. No
      coordinates are sent with this, so a menu will be generated
      unless ImapMenu is set to
      none.
    

      
    menu
    
      
    Synonymous with map.
    

      
    referer
    

      
    Equivalent to the URL of the referring document. Defaults
      to http://servername/ if no Referer:
      header was present.
    

      
    nocontent
    

      
    Sends a status code of 204 No Content,
      telling the client to keep the same page displayed. Valid for
      all but base.
    

      
    error
    

      
    Fails with a 500 Server Error. Valid for all
      but base, but sort of silly for anything but
      default.
    
      
    
    

    
    Coordinates
    

      
    
      
    0,0 200,200
    

      
    A coordinate consists of an x and a y
      value separated by a comma. The coordinates are separated
      from each other by whitespace. To accommodate the way Lynx
      handles imagemaps, should a user select the coordinate
      0,0, it is as if no coordinate had been
      selected.
    
      
    

    

    
    Quoted Text
    

      
    
      
    "Menu Text"
    

      
    After the value or after the coordinates, the line
      optionally may contain text within double quotes. This string
      is used as the text for the link if a menu is
      generated:
    

      
    
        <a href="http://example.com/">Menu text</a>
      
    

      
    If no quoted text is present, the name of the link will be
      used as the text:
    

      
    
        <a href="http://example.com/">http://example.com</a>
      
    

      
    If you want to use double quotes within this text, you have to
      write them as &quot;.

    ImapBase Directive
    

    

    Description:Default base for imagemap files
    

    Syntax:ImapBase map|referer|URL
    

    Default:ImapBase http://servername/
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_imagemap
    

    
    
    The ImapBase directive sets the default
    base used in the imagemap files. Its value is
    overridden by a base directive within the imagemap
    file. If not present, the base defaults to
    http://servername/.

    ImapDefault Directive
    

    

    Description:Default action when an imagemap is called with coordinates
that are not explicitly mapped
    

    Syntax:ImapDefault error|nocontent|map|referer|URL
    

    Default:ImapDefault nocontent
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_imagemap
    

    
    
    The ImapDefault directive sets the default
    default used in the imagemap files. Its value is
    overridden by a default directive within the
    imagemap file. If not present, the default action
    is nocontent, which means that a 204 No
    Content is sent to the client. In this case, the client
    should continue to display the original page.
    


    

    top
    

    ImapMenu Directive
    

    

    Description:Action if no coordinates are given when calling
an imagemap
    

    Syntax:ImapMenu none|formatted|semiformatted|unformatted
    

    Default:ImapMenu formatted
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:Indexes
    

    Status:Base
    

    Module:mod_imagemap
    

    
    
    The ImapMenu directive determines the
    action taken if an imagemap file is called without valid
    coordinates.
    

    
    
      
    none
    
      
    If ImapMenu is none, no menu is generated,
      and the default action is performed.
    

      
    formatted
    
      
    A formatted menu is the simplest menu.
      Comments in the imagemap file are ignored. A level one header
      is printed, then an hrule, then the links each on a separate
      line. The menu has a consistent, plain look close to that of
      a directory listing.
    

      
    semiformatted
    
      
    In the semiformatted menu, comments are
      printed where they occur in the imagemap file. Blank lines
      are turned into HTML breaks. No header or hrule is printed,
      but otherwise the menu is the same as a
      formatted menu.
    

      
    unformatted
    
      
    Comments are printed, blank lines are ignored. Nothing is
      printed that does not appear in the imagemap file. All breaks
      and headers must be included as comments in the imagemap
      file. This gives you the most flexibility over the appearance
      of your menus, but requires you to treat your map files as
      HTML instead of plaintext.

    specified directory after startup, but before accepting requests
    over the 'net.
    
    
    Note that running the server under chroot is not simple,
    and requires additional setup, particularly if you are running
    scripts such as CGI or PHP.  Please make sure you are properly
    familiar with the operation of chroot before attempting to use
    this feature.

    Group Directive
    

    

    Description:Group under which the server will answer
requests
    

    Syntax:Group unix-group
    

    Default:Group #-1
    

    Context:server config
    

    Status:Base
    

    Module:mod_unixd
    

    
    
    The Group directive sets the group under
    which the server will answer requests. In order to use this
    directive, the server must be run initially as root. If
    you start the server as a non-root user, it will fail to change to the
    specified group, and will instead continue to run as the group of the
    original user. Unix-group is one of:
    

    
    
      
    A group name
    
      
    Refers to the given group by name.
    

      
    # followed by a group number.
    
      
    Refers to a group by its number.
    
    
    

    
    Example
    Group www-group
    

    

    
    It is recommended that you set up a new group specifically for
    running the server. Some admins use user nobody,
    but this is not always possible or desirable.
    

    
    Security
    
      
    Don't set Group (or User) to root unless
      you know exactly what you are doing, and what the dangers are.

    Suexec Directive
    

    

    Description:Enable or disable the suEXEC feature
    

    Syntax:Suexec On|Off
    

    Default:On if suexec binary exists with proper owner and mode,
Off otherwise
    

    Context:server config
    

    Status:Base
    

    Module:mod_unixd
    

    
    
    When On, startup will fail if the suexec binary doesn't exist
    or has an invalid owner or file mode.
    
    
    When Off, suEXEC will be disabled even if the suexec binary exists
    and has a valid owner and file mode.

    User Directive
    

    

    Description:The userid under which the server will answer
requests
    

    Syntax:User unix-userid
    

    Default:User #-1
    

    Context:server config
    

    Status:Base
    

    Module:mod_unixd
    

    
    
    The User directive sets the user ID as
    which the server will answer requests. In order to use this
    directive, the server must be run initially as root.
    If you start the server as a non-root user, it will fail to change
    to the lesser privileged user, and will instead continue to run as
    that original user. If you do start the server as root,
    then it is normal for the parent process to remain running as root.
    Unix-userid is one of:
    

    
    
      
    A username
    
      
    Refers to the given user by name.
    

      
    # followed by a user number.
    
      
    Refers to a user by its number.
    
    
    

    
    The user should have no privileges that result in it being
    able to access files that are not intended to be visible to the
    outside world, and similarly, the user should not be able to
    execute code that is not meant for HTTP requests. It is
    recommended that you set up a new user and group specifically for
    running the server. Some admins use user nobody, but
    this is not always desirable, since the nobody user
    can have other uses on the system.
    

    
    Security
    
      
    Don't set User (or Group) to root unless
      you know exactly what you are doing, and what the dangers are.

    Özet
    

    
    Bu modül istemci isteklerinin adli günlük kayıtlarının tutulmasını
      sağlar. Günlük kaydı bir istek işlenmeden önce ve sonra olmak üzere iki
      kere yapılır, böylece günlükte her istek için iki girdi bulunur. Adli
      günlükleyici çok sıkı kurallara tabidir, yani:
    

    
      
    
    • Biçem sabittir. Günlük kayıt biçemi çalışma anında değiştirilemez.
      • 
    
    • Veriyi yazamadığı takdirde çocuk süreç beklemeksizin çıkar ve
      (CoreDumpDirectory
      yapılandırmasına bağlı olarak) bir core dosyası dökümler.
      • 
    
    

    
    Dağıtımın support dizininde bulunan
      check_forensic betiği adli günlük dosyalarının
      değerlendirilmesinde yardımcı olabilir.
    

    


    top
    

    

    Adli Günlük Biçemi
    
    
    Her istek günlüğe iki defa kaydedilir. İlki, işlemin başlangıcında
      (yani, başlıklar alındıktan hemen sonra), ikincisi ise istek işlem
      gördükten sonra normal günlüklemenin yapıldığı sırada yapılır.
    

    
    Her isteği betimlemek için eşsiz bir istek kimliği atanır. Bu adli
      kimliğin normal günlüğe de yazılması istenirse bu
      %{forensic-id}n biçem dizgesi ile yapılabilir.
      mod_unique_id kullanılıyorsa, onun ürettiği kimlik
      kullanılır.
    

    
    İlk satır günlüğe, adli kimliği, istek satırını ve alınan tüm
      başlıkları boru karakterleri (|) ile ayrılmış olarak
      kaydeder. Aşağıda bir örneğe yer verilmiştir (hepsi bir satırdadır):
    

    
    
        +yQtJf8CoAB4AAFNXBIEAAAAA|GET /manual/de/images/down.gif
        HTTP/1.1|Host:localhost%3a8080|User-Agent:Mozilla/5.0 (X11;
        U; Linux i686; en-US; rv%3a1.6) Gecko/20040216
        Firefox/0.8|Accept:image/png, etc...
    
    

    
    Başlangıçtaki artı imi bu günlük satırının istekle ilgili ilk günlük
      kaydı olduğunu belirtir. İkinci satırda bunun yerini bir eksi imi
      alır:
    

    
    
      -yQtJf8CoAB4AAFNXBIEAAAAA
    
    

    
    check_forensic betiği komut satırı argümanı olarak günlük
      dosyasının ismini alır. Bu +/- kimlik
      çiftlerine bakarak tamamlanmamış istekler varsa bunlar hakkında
      uyarır.
    

    top
    

    

    Güvenlik Kaygıları
    
    
    Günlük dosyarının kaydedildiği dizine sunucuyu başlatan kullanıcı
      dışında diğer kullanıcılar tarafından yazılabiliyor olması halinde
      güvenliğinizden nasıl feragat etmiş olacağınız güvenlik ipuçları
      belgesinde açıklanmıştır.
    
    
    Günlük dosyaları, Authorization: başlıklarının (parola
      içerebilen) içerikleri gibi hassas veriler içerebileceğinden bunların
      sunucuyu başlatan kullanıcıdan başkası tarafından okunamaması sağlanmış
      olmalıdır.

    ForensicLog Yönergesi
    

    

    Açıklama:Adli günlük için dosya ismini belirler.
    

    Sözdizimi:ForensicLog dosya-adı|borulu-süreç
    

    Bağlam:sunucu geneli, sanal konak
    

    Durum:Eklenti
    

    Modül:mod_log_forensic
    

    
    
    ForensicLog yönergesi adli inceleme için
      sunucuya yapılan istekleri günlüğe kaydetmekte kullanılır. Her günlük
      girdisine, normal CustomLog yönergesinde kullanılarak istekle
      ilişkilendirilebilen eşsiz bir kimlik atanır.
      mod_log_forensic modülü, aktarım günlüğünün biçem
      dizgesinde %{forensic-id}n şeklinde kullanılmak üzere
      forensic-id adı verilen bir dizgecik oluşturur.
    

    
    Günlüğün yazılacağı yeri belirleyen argüman şu iki değerden birini
      alabilir:
    

    
    
      
    dosya-adı
    
      
    ServerRoot yönergesinin
        değerine göreli bir dosya ismi.
    

      
    borulu-süreç
    
      
    "|" boru karakteri ile öncelenmiş olarak günlük
        bilgisini standart girdisinden kabul edecek sürecin ismi (veya komut
        satırı). Program adının ServerRoot yönergesinin değerine göre belirtildiği
        varsayılır.

      
    Güvenlik:
    
      
    Bir borulu süreç kullanılmışsa, süreç httpd’yi
        başlatan kullanıcı tarafından başlatılacaktır. Sunucu root tarafından
        başlatılıyorsa bu root olacaktır; bu bakımdan günlük kaydını alacak
        programın güvenilir olması veya daha az yetkili bir kullanıcıya geçiş
        yapması önemlidir.
    
      
    

      
    Bilginize
    
        
    Dosya yolunu belirtirken tersbölü çizgisi kullanılan Unix dışı
          platformlarda bile yapılandırma dosyasında bu amaçla normal bölü
          çizgilerini kullanmaya özen gösterilmelidir.

    Module Apache mod_vhost_alias
    

    

    Langues Disponibles:  en  |

    Description:Permet de configurer dynamiquement l'hébergement virtuel de
masse
    

    Statut:Extension
    

    Identificateur de Module:vhost_alias_module
    

    Fichier Source:mod_vhost_alias.c
    

    Sommaire
    

    
    Ce module permet de créer des serveurs virtuels configurés
    dynamiquement, en autorisant l'utilisation de l'adresse IP et/ou de
    l'en-tête Host: de la requête HTTP comme partie du nom
    de chemin afin de déterminer les fichiers à servir. Ceci facilite la
    gestion d'un grand nombre de serveurs virtuels possèdant des
    configurations similaires.
    

    
    Note
    
      
    Si les modules mod_alias ou
      mod_userdir sont utilisés pour traduire les URIs
      en noms de fichiers, ils l'emportent sur les directives du module
      mod_vhost_alias décrites ci-dessous. Par
      exemple, la configuration suivante fera correspondre 
      /cgi-bin/script.pl à 
      /usr/local/apache2/cgi-bin/script.pl dans tous les cas :
    

      
    ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/"
VirtualScriptAlias "/never/found/%0/cgi-bin/"

    Interpolation du nom de répertoire
    
    

    
    Toutes les directives de ce module insèrent une chaîne dans un
    nom de chemin. La chaîne insérée (que nous appellerons maintenant le
    "nom") peut être soit le nom du serveur (voir la directive
    UseCanonicalName pour les
    détails sur la manière dont il est déterminé), soit l'adresse IP du
    serveur virtuel hébergé par le serveur sous la forme d'un quadruplet
    d'octets séparés par des points. L'insertion est contrôlée par des
    spécificateurs inspirés de printf et possèdant de
    nombreux formats :
    


    


    %%
insère un %
    


    %p
insère le numéro de port du serveur virtuel
    


    %N.M
insère le nom (en partie)
    


    

    
    N et M permettent de spécifier des
    sous-chaînes du nom. N sélectionne un des composants du
    nom séparés par des points, et M sélectionne des
    caractères à l'intérieur de ce que N a sélectionné.
    M est optionnel et sa valeur par défaut est 0 s'il
    n'est pas spécifié ; le point doit être présent si et seulement si
    M l'est aussi. Les modes d'insertion sont les suivants
    :
    

    
    
      
      
    0
      le nom en entier
    

      
    1
      la première partie
    

      
    2
      la seconde partie
    

      
    -1
      la dernière partie
    

      
    -2
      l'avant-dernière partie
    

      
    2+
      toutes les parties à partir de la seconde
    

      
    -2+
      toutes les parties jusqu'à l'avant-dernière
    

      
    1+ et -1+
      identique à 0
    
    
    

    
    Si N ou M est plus grand que le nombre
    de parties disponibles, seul un caractère de soulignement est
    inséré.
    


    top
    

    

    Exemples
    
    

    
    Pour des serveurs virtuels simples à base de nom, utilisez les
    directives suivantes dans le fichier de configuration de votre
    serveur :
    

    
    UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/vhosts/%0"
    


    
    Une requête pour
    http://www.example.com/repertoire/fichier.html
    concernera alors la ressource
    /usr/local/apache/vhosts/www.example.com/repertoire/fichier.html.
    
    

    
    Pour un très grand nombre de serveurs virtuels, il est avantageux
    d'organiser les fichiers de façon à réduire la taille du répertoire
    vhosts. Pour ce faire, insérez les lignes suivantes
    dans votre fichier de configuration :
    

    
    UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2"
    


    
    Une requête pour
    http://www.domaine.example.com/repertoire/fichier.html
    concernera alors la ressource
    /usr/local/apache/vhosts/example.com/d/o/m/domaine/repertoire/fichier.html.
    

    
    Une répartition plus régulière des fichiers peut être obtenue en
    partant de la fin d'un composant du nom, comme dans l'exemple
    suivant :
    


    VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.-1/%2.-2/%2.-3/%2"
    


    
    La requête précédente concernerait alors
    /usr/local/apache/vhosts/example.com/e/n/i/domaine/repertoire/fichier.html.
    

    
    Vous pouvez également utiliser : 
    


    VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2.4+"
    


    
    La requête précédente concernerait alors
    /usr/local/apache/vhosts/example.com/d/o/m/aine/repertoire/fichier.html.
    

    
    Une demande très courante des utilisateurs concerne la possibilité de
    faire correspondre plusieurs racines de documents à plusieurs
    domaines, sans avoir à se préoccuper de la longueur ou du nombre de
    parties du nom d'hôte faisant partie de la requête. Si le nom d'hôte
    de la requête est sub.www.domain.example.com au lieu de
    simplement www.domain.example.com, alors en utilisant
    %3+, la racine des documents sera
    /usr/local/apache/vhosts/domain.example.com/... au
    lieu du répertoire example.com attendu. Dans ce genre
    de situation, il peut s'avérer préférable d'utiliser la combinaison
    %-2.0.%-1.0 qui fournira toujours le nom de domaine et
    le tld, par exemple example.com sans tenir compte du
    nombre de sous-domaines ajoutés au nom d'hôte. Dans ces conditions,
    il est possible d'élaborer une configuration qui associera les
    sous-domaines de premier, second et troisième niveau au même
    répertoire :

    

    VirtualDocumentRoot "/usr/local/apache/vhosts/%-2.0.%-1.0"
    


    
Dans l'exemple ci-dessus, www.example.com,
www.sub.example.com ou example.com
correspondront tous au répertoire
/usr/local/apache/vhosts/example.com.

    



    
    Pour l'hébergement virtuel à base d'adresse IP, vous pouvez
    insérer les lignes suivantes dans votre fichier de configuration
    :
    

    
    UseCanonicalName DNS
VirtualDocumentRootIP "/usr/local/apache/vhosts/%1/%2/%3/%4/docs"
VirtualScriptAliasIP  "/usr/local/apache/vhosts/%1/%2/%3/%4/cgi-bin"
    


    
    Si l'adresse IP de www.domaine.example.com est
    10.20.30.40, une requête pour
    http://www.domaine.example.com/repertoire/fichier.html
    concernera la ressource
    /usr/local/apache/vhosts/10/20/30/40/docs/repertoire/fichier.html.
    Une requête pour
    http://www.domaine.example.com/cgi-bin/script.pl
    concernera la ressource
    /usr/local/apache/vhosts/10/20/30/40/cgi-bin/script.pl.
    

    
    Si vous voulez insérer le caractère . dans une
    directive VirtualDocumentRoot, et si cela crée un
    conflit avec un spécificateur %, vous pouvez contourner
    le problème de la manière suivante :
    


    VirtualDocumentRoot "/usr/local/apache/vhosts/%2.0.%3.0"
    


    
    Une requête pour
    http://www.domaine.example.com/repertoire/fichier.html
    concernera alors la ressource
    /usr/local/apache/vhosts/domaine.exemple/repertoire/fichier.html.
    

    
    Les spécificateurs de format %V et %A
    de la directive LogFormat s'avèrent très utiles
    lorsqu'ils sont utilisés en conjonction avec ce module.

    Directive VirtualDocumentRoot
    

    

    Description:Permet une configuration dynamique de la racine des
documents d'un serveur virtuel donné
    

    Syntaxe:VirtualDocumentRoot répertoire-interpolé|none
    

    Défaut:VirtualDocumentRoot none
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_vhost_alias
    

    

    
    La directive VirtualDocumentRoot vous
    permet de spécifier où le serveur HTTP Apache pourra trouver vos
    documents en se basant
    sur le nom du serveur. Le résultat de l'expansion du
    répertoire-interpolé est utilisé comme racine de
    l'arborescence des documents d'une manière similaire à l'argument de
    la directive DocumentRoot. Si
    répertoire-interpolé a pour valeur none, la
    directive VirtualDocumentRoot est désactivée.
    Cette directive ne peut pas être utilisée dans le même contexte que
    la directive VirtualDocumentRootIP.
    


    Note
    
La directive VirtualDocumentRoot l'emporte sur
toute directive DocumentRoot
définie dans le même contexte ou dans des contextes enfants. Le fait de
définir une directive VirtualDocumentRoot dans le
contexte du serveur principal va effectivement l'emporter sur toute
directive DocumentRoot définie dans
un serveur virtuel quelconque, si vous n'avez pas défini
VirtualDocumentRoot à None dans ce
serveur virtuel.

    La directive VirtualDocumentRootIP est
identique à la directive VirtualDocumentRoot à l'exception
près qu'elle utilise l'adresse IP du serveur virtuel pour
l'interpolation du répertoire à la place du nom du serveur.

    La directive VirtualScriptAlias vous
    permet de spécifier où Apache httpd pourra trouver les scripts CGI selon une
    méthode similaire à celle qu'utilise la directive VirtualDocumentRoot pour les
    autres documents. Elle recherche des requêtes dont l'URI commence
    par /cgi-bin/, comme le ferait la directive ScriptAlias.

    Compatibilité:Disponible à partir de la version 2.4.30 du serveur HTTP Apache.
    

    Sommaire
    

    
    Pour pouvoir fonctionner, ce module requiert le chargement préalable de
    mod_proxy. Il fournit le support du protocole
    UWSGI.
    

    
    Pour être en mesure de gérer le protocole UWSGI, le serveur doit donc
    pouvoir disposer des modules mod_proxy et
    mod_proxy_uwsgi.
    

    
    Avertissement
    
      
    N'activez le mandatement que si vous avez sécurisé votre serveur. Les serveurs
      mandataires ouverts sont dangereux pour votre réseau, mais aussi pour
      Internet en général.

    Passerelle simple
    ProxyPass "/uwsgi-bin/" "uwsgi://localhost:4000/"
    

    

    
    La passerelle à répartition de charge nécessite
    mod_proxy_balancer et au moins un module implémentant un
    algorithme de répartition de charge comme
    mod_lbmethod_byrequests, en plus des modules de mandatement
    listés ci-dessus. Par défaut, c'est mod_lbmethod_byrequests
    qui sera utilisé, et c'est donc ce dernier qui sera utilisé dans l'exemple
    suivant :
    

    
    Passerelle à répartition de charge
    ProxyPass "/uwsgi-bin/" "balancer://somecluster/"
<Proxy balancer://somecluster>
    BalancerMember uwsgi://localhost:4000

    Zusammenfassung
    

    
    Dieses Multi-Processing-Modul (MPM) implementiert einen Hybrid-Server
    mit Multi-Thread und Multi-Prozess-Unterstützung. Durch die Verwendung
    von Threads für die Bedienung von Anfragen ist er in der Lage,
    eine große Anzahl von Anfragen mit weniger Systemressourcen als
    ein Prozess-basierter Server zu bedienen. Er behält jedoch viel von
    der Stabilität eines Prozess-basierten Servers bei, indem er
    mehrere Prozesse verfügbar hält, jeden mit etlichen Threads.
    

    
    Die wichtigsten Direktiven zur Steuerung des MPMs sind ThreadsPerChild, welche die Anzahl
    der Threads beeinflusst, die von jedem Kindprozess verwendet werden, und
    MaxClients, welche die
    maximale Gesamtzahl an Threads regelt, die gestartet werden
    können.
    

    


    top
    

    

    Arbeitsweise
    
    
    Ein einzelner Steuerprozess (der Elternprozess) ist für den
    Start der Kindprozesse verantwortlich. Jeder Kindprozess erstellt eine
    feste Anzahl von Server-Threads, wie durch die ThreadsPerChild-Direktive
    angegeben, sowie einen "Listener-Thread", der auf Verbindungen wartet und
    diese an einen Server-Thread zur Bearbeitung weiterreicht, sobald sie
    eintreffen.
    

    
    Der Apache versucht immer, einen Vorrat von freien oder
    unbeschäftigten Threads zu verwalten, die zur Bedienung
    hereinkommender Anfragen bereit stehen. Auf diese Weise brauchen
    Clients nicht auf die Erstellung eines neuen Threads oder Prozesses
    zu warten, bevor ihre Anfrage bedient werden kann. Die Anzahl der
    Prozesse, die anfangs gestartet wird, wird mit der Direktive
    StartServers festgelegt.
    Dann, während des Betriebes, berechnet der Apache die Gesamtzahl
    der unbeschäftigten Threads und forkt oder beendet Prozesse, um diese
    Anzahl innerhalb der durch MinSpareThreads und MaxSpareThreads angegebenen Grenzen
    zu halten. Da dieser Prozess sehr selbstregulierend ist, ist es nur selten
    notwendig, die Voreinstellung dieser Direktiven zu ändern. Die
    maximale Anzahl Clients, die gleichzeitig bedient werden kann (d.h.
    die maximale Gesamtzahl der Threads in allen Prozessen), wird mit der
    Direktive MaxClients
    festgelegt. Die maximale Anzahl der aktiven Kindprozesse ergibt sich aus
    MaxClients dividiert durch
    ThreadsPerChild.
    

    
    Zwei Direktiven legen harte Limits für die Anzahl der aktiven
    Kindprozesse fest und können nur geändert werden, indem der Server
    komplett gestoppt und dann wieder neu gestartet wird. ServerLimit stellt die obere Grenze für
    die Anzahl der aktiven Kindprozesse dar und muss größer oder
    gleich dem Quotienten aus MaxClients und ThreadsPerChild sein. ThreadLimit ist die obere Grenze für
    die Anzahl der Server-Threads und muss größer oder gleich
    ThreadsPerChild sein. Sofern für
    diese Direktiven keine Voreinstellungen verwendet werden, sollten sie vor
    allen anderen worker-Direktiven platziert werden.
    

    
    Neben den normalen aktiven Kindprozessen gibt es möglicherweise noch
    zusätzliche Kindprozesse, welche gerade beendet werden, wo allerdings
    zumindest noch ein Server-Thread eine existierende Verbindung bearbeitet.
    Obwohl die tatsächlich zu erwartende Anzahl deutlich kleiner ist,
    können bis zu MaxClients
    solcher Prozesse auftreten. Dieses Verhalten können Sie vermeiden,
    indem Sie die Terminierung einzelner Kindprozesse wie folgt abschalten:
    

    

    
    Eine typische Konfiguration der Prozess-Thread-Steuerung für
    das MPM worker könnte wie folgt aussehen:
    

    
    
      ServerLimit         16
    
      StartServers         2
    
      MaxClients         150
    
      MinSpareThreads     25
    
      MaxSpareThreads     75
    
      ThreadsPerChild     25
    
    

    
    Während der Elternprozess unter Unix normalerweise als
    root gestartet wird, um sich an Port 80 binden zu können,
    werden die Kindprozesse und Threads unter einem weniger privilegierten
    Benutzer gestartet. Die Direktiven User und Group werden dazu verwendet, die
    Privilegien der Apache-Kindprozesse festzulegen. Die Kindprozesse
    müssen in der Lage sein, alle Inhalte zu lesen, die sie ausliefern
    sollen, sollten darüber hinaus jedoch so wenig wie möglich Rechte
    besitzen. Zusätzlich, solange nicht suexec verwendet wird, legen diese
    Direktiven auch die Privilegien fest, die von CGI-Skripts
    geerbt werden.
    

    
    MaxRequestsPerChild
    bestimmt, wie häufig der Server Prozesse erneuert, indem er alte
    beendet und neue startet.

    概要
    

    
    コンテントネゴシエーション、より正確にはコンテンツの選択機能は、
    複数用意されているドキュメントから、クライアントの能力に一番合った
    ドキュメントを選択する機能です。この実装は二つあります。
    

    
      
      
    • タイプマップ (type-map
      ハンドラで扱われるファイル)。これは variants
      を含んでいるファイルを明示的に指定します。
      • 

      
    • MultiViews の探索 (MultiViews Option で有効になります)。
      サーバが暗黙の内にファイル名のパターンマッチを行ない、
      その結果から選択します。
      • 
    
    

    


    top
    

    

    タイプマップ
    
    
    タイプマップは RFC 822 のメールヘッダに類似した書式です。
    ドキュメントの記述が空行で分離されて書かれていて、ハッシュ文字
    ('#') で始まる行はコメントとして扱われます。
    ドキュメントの説明は複数のヘッダレコードから構成されます。
    レコードは、続きの行が空白で始まっていると複数の行にまたがります。
    最初の空白が消去されて、前の行とつなげて 1 行として扱われます。
    ヘッダレコードはキーワード名の後に値が続くという形式で、
    キーワード名は常にコロンで終わります。空白はヘッダ名と値の間、
    値のトークンの間に入れることができます。
    使用可能なヘッダは以下のとおりです:
    

    
    
      
    Content-Encoding:
    
      
    ファイルのエンコーディング。Apache は AddEncoding ディレクティブ
      で定義されたエンコーディングだけを認識します。通常 compress
      されたファイルのための x-compress と gzip
      されたファイルのための x-gzip を含みます。
      エンコーディングの比較をするときは、接頭辞 x-
      は無視されます。
    

      
    Content-Language:
    
      
    インターネット標準の言語タグ 
      (RFC 1766)
      で定義されている言語の種類。例えば、en
      は英語を表します。
      複数の言語が格納される場合はコンマで区切られます。
    

      
    Content-Length:
    
      
    ファイルの長さ (バイト数)。
      このヘッダがない場合、ファイルの実際の長さが使用されます。
    

      
    Content-Type:
    
      
    ドキュメントの MIME
      メディアタイプ、オプショナルなパラメータ付き。パラメータの構文は
      name=value
      で、メディアタイプや他のパラメータとはセミコロンで分離されます。
      共通のパラメータは以下のとおり:

        
    
          
    level
    
          
    メディアタイプのバージョンを示す整数。
          text/html では 2 がデフォルトで、その他の場合は
          0 がデフォルトです。
    

          
    qs
    
          
    クライアントの能力に関係なく、variant
          を他と比較したときの相対的な「品質」で、0.0 から 1.0
          の範囲の浮動点小数。
          例えば、写真を表現しようとしているときは普通は JPEG
          ファイルの方が ASCII ファイルよりも高い品質になります。
          しかし、リソースが ASCII アートで表現されているときは、ASCII
          ファイルの方が JPEG
          ファイルよりも高い品質になります。このように、qs
          はリソース毎に特有の値を取ります。
          
    
        
    

        
    例
    
          Content-Type: image/jpeg; qs=0.8
        
    
      
    

      
    URI:
    
      
    (指定のメディアタイプ、コンテントエンコーディングの) variant の
      ファイルの uri.  これは、マップファイルからの相対 URL として
      解釈されます。同じサーバに存在しなければならず、クライアントが
      直接リクエストしたときにアクセスを許可されるものでなければなりません。
    

      
    Body:
    
      
    Apache 2.0 で新設されたこの Body ヘッダを使って、
      リソースの実際の内容をタイプマップファイルに書くことができます。
      このヘッダは本文の内容の区切りとなる文字列で始まる必要があります。
      タイプマップファイルの続く行は、区切り文字列が見つかるまで、
      リソースの本文になります。

      
    Example:
    
        Body:----xyz----
    
        <html>
    
        <body>
    
        <p>Content of the page.</p>
    
        </body>
    
        </html>
    
        ----xyz----
      
    
      
    
    
    

    top
    

    

    MultiViews
    
    
    MultiViews 探索は、Multiviews Options ディレクティブにより有効になります。
    サーバが /some/dir/foo
    へのリクエストを受け取り、/some/dir/foo が存在
    しない場合、サーバはディレクトリを読んで、
    foo.* にあてはまる全てのファイルを探し、
    事実上それらのファイルをマップするタイプマップを作ります。
    そのとき、メディアタイプとコンテントエンコーディングは、
    そのファイル名を直接指定したときと同じものが割り当てられます。
    それからクライアントの要求に一番合うものを選び、
    そのドキュメントを返します。
    

    
    ファイルを選択する際に、関連するコンテントネゴシエーションの
    メタ情報を持たないファイルについて、判定を行うかどうかを
    MultiViewsMatch
    ディレクティブで設定します。

    このディレクティブが設定されていると、コンテントネゴシエーション

    これは、プロキシの後ろにいるクライアントが能力に一番合った
    ドキュメントではなく、
    キャッシュをより効果的にするものを得る可能性があるということです。
    

    
    このディレクティブは HTTP/1.0 ブラウザからのリクエスト
    のみに適用されます。HTTP/1.1 は、
    交渉されたドキュメントのキャッシュに対してずっとよい制御が可能なので、
    このディレクティブは HTTP/1.1 のリクエストには影響しません。
    
    
    2.0 より前のバージョンでは、
    CacheNegotiatedDocs は引数を取らず、
    ディレクティブが存在することで on の動作をしていました。

    ForceLanguagePriority Prefer は、同等の選択肢が
    いくつかあるときに、HTTP の 300 (MULTIPLE CHOICES) を返す代わりに、
    LanguagePriority を使って一つだけドキュメントを返すように
    します。以下のディレクティブが指定されていて、ユーザの Accept-Language
    ヘッダでは en と de の品質が共に
    .500 (同じくらい許容) であるときは、
    最初にマッチする variant の en が送られます。

    LanguagePriority は、MultiViews
    リクエストを扱うときに、クライアントが優先順位を提供していない場合の
    言語の優先順位を設定します。MIME-lang
    のリストが優先度の降順に並びます。
    

    
    Example:
    
      LanguagePriority en fr de
    
    

    
    foo.html がリクエストされ、foo.html.fr
    と foo.html.de が両方存在し、
    ブラウザが言語の優先順位を提供してない場合は
    foo.html.fr が返されます。
    

    
    このディレクティブは他の方法で「最善」
    の言語が決定できないときか、ForceLanguagePriority ディレクティブが
    None 以外のときにのみ効果があることに注意してください。
    一般的には、サーバ側ではなくクライアント側で好みの言語を決定します。

    Module Apache mod_authn_anon
    

    

    Langues Disponibles:  en  |

    Description:Permet un accès "anonyme" à des zones
protégées
    

    Statut:Extension
    

    Identificateur de Module:authn_anon_module
    

    Fichier Source:mod_authn_anon.c
    

    Compatibilité:Disponible depuis la version 2.1 d'Apache
    

    Sommaire
    

    
    Ce module permet aux frontaux d'authentification comme
    mod_auth_basic d'authentifier les utilisateurs
    à la manière des sites FTP anonymes, c'est à dire
    en fournissant l'identifiant utilisateur spécial 'anonymous' et
    l'adresse email comme mot de passe. Ces adresses email peuvent être
    journalisées.
    

    
    En combinaison avec d'autres méthodes de contrôle d'accès (base
    de données), ce module permet d'effectuer un véritable suivi des
    utilisateurs et une personnalisation de leurs accès en fonction de
    leur profil, tout en conservant l'accessibilité du site aux
    utilisateurs 'non enregistrés'. Un avantage du suivi des
    utilisateurs basé sur l'authentification réside dans le fait qu'il
    est, à l'opposé des cookies magiques et des drôles d'URLs avec
    préfixes ou suffixes, entièrement indépendant du navigateur et qu'il
    permet de partager des URLs entre plusieurs utilisateurs.
    

    
    Si l'on utilise le module mod_auth_basic, le
    module mod_authn_anon est invoqué en affectant la
    valeur anon à la directive AuthBasicProvider.
    

    


    top
    

    

    Exemple
    
    
    L'exemple ci-dessous présente un exemple de combinaison avec
    l'authentification à base de fichier htpasswd "normale", et permet
    la connexion d'utilisateurs en tant qu'invités avec les propriétés
    suivantes :
    

    
      
      
    • Il incite l'utilisateur à fournir un identifiant.
      (Anonymous_NoUserID)
      • 

      
    • Il incite l'utilisateur à fournir un mot de passe.
      (Anonymous_MustGiveEmail)
      • 

      
    • Le mot de passe fourni doit être une adresse email valide,
      c'est à dire contenant au moins un '@' et un '.'.
      (Anonymous_VerifyEmail)
      • 

      
    • Les valeurs possibles pour l'identifiant utilisateur sont
      anonymous, guest, www, test ou welcome, et la
      vérification n'est pas sensible à la casse.
      (Anonymous)
      • 

      
    • Les adresses email entrées dans le champ passwd sont
      enregistrées dans le fichier journal des erreurs.
      (Anonymous_LogEmail)
      • 
    
    

    
    Exemple
    <Directory "/var/www/html/private">
    AuthName "Use 'anonymous' & Email address for guest entry"
    AuthType Basic
    AuthBasicProvider file anon
    AuthUserFile "/path/to/your/.htpasswd"

    Anonymous_NoUserID off
    Anonymous_MustGiveEmail on
    Anonymous_VerifyEmail on
    Anonymous_LogEmail on
    Anonymous anonymous guest www test welcome

    Require valid-user
</Directory>

    Directive Anonymous
    

    

    Description:Définit la liste des identifiants utilisateur autorisés à
accéder sans vérification du mot de passe
    

    Syntaxe:Anonymous utilisateur [utilisateur]
...
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_authn_anon
    

    
    
    Une liste d'un ou plusieurs identifiants utilisateur spéciaux
    autorisés à accéder sans vérification du mot de passe. Les
    identifiants doivent être séparés par un espace. Pour spécifier un
    identifiant contenant un espace, on peut utiliser les guillemets '
    ou ", ou le caractère d'échappement \.
    

    
    Veuillez noter que la vérification n'est pas sensible à
    la casse.
    
    Il est fortement conseillé d'intégrer l'utilisateur spécial
    'anonymous' dans la liste des identifiants.
    

    
    Exemple:
    Anonymous anonymous "Not Registered" "I don't know"
    

    

    
    Dans cet exemple, l'utilisateur peut accéder au site sans
    vérification du mot de passe en utilisant l'identifiant "anonymous",
    "Not Registered", "I Don't Know" ou encore "AnonyMous".
    

    
    Depuis Apache 2.1, il est possible de remplacer la liste des
    identifiants autorisés par le caractère "*", ce qui
    permet d'utiliser n'importe quel identifiant pour pouvoir
    accéder au site.

    Détermine si l'utilisateur doit spécifier une adresse email comme
    mot de passe. Lorsque cette directive est définie à On,
    l'abscence de mot de passe est interdite.

    Défaut:Anonymous_NoUserID Off
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Extension
    

    Module:mod_authn_anon
    

    
    
    Lorsque cette directive est définie à On, les
    utilisateurs peuvent laisser le champ identifiant vide (et peut-être
    aussi le champ mot de passe selon la définition de la directive
    Anonymous_MustGiveEmail). Ceci
    peut s'avérer très utile pour les utilisateurs de MS-Explorer qui
    n'ont pour seule possibilité que d'appuyer sur Entrée ou de cliquer
    directement sur le bouton OK, ce qui semble être une réaction
    naturelle.

    Directive Anonymous_VerifyEmail
    

    

    Description:Détermine s'il faut vérifier que le format de l'adresse

    Statut:Extension
    

    Module:mod_authn_anon
    

    
    
    Lorsque cette directive est définie à On, Apache
    vérifie que le 'mot de passe' entré contient au moins un '@' et un
    '.' afin d'inciter les utilisateurs à fournir des adresses email
    valides (voir ci-dessus la directive Anonymous_LogEmail).

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:外部 CGI デーモンを使った CGI スクリプトの実行
    

    ステータス:Base
    

    モジュール識別子:cgid_module
    

    ソースファイル:mod_cgid.c
    

    互換性:Unix のスレッド MPM のみ
    

    概要
    

    
    最適化が施されていることと、以下で説明されている追加の ScriptSock ディレクティブを除いては、
    mod_cgid は mod_cgi と同様の
    動作をします。Apache と CGI に関する詳細は
    mod_cgi の概要を読んでください。
    

    
    Unix オペレーティングシステムの中には、マルチスレッドのサーバから
    プロセスを fork するのが非常にコストの高い動作になっているものがあります。
    理由は、新しいプロセスが親プロセスのスレッドすべてを複製するからです。
    各 CGI 起動時にこのコストがかかるのを防ぐために、mod_cgid
    は子プロセスを fork して CGI スクリプトを実行するための
    外部デーモンを実行します。
    主サーバは unix ドメインソケットを使ってこのデーモンと通信します。
    

    
    コンパイル時にマルチスレッド MPM が選ばれたときは
    mod_cgi の代わりに必ずこのモジュールが使用されます。
    ユーザのレベルではこのモジュールの設定と動作は mod_cgi
    とまったく同じです。唯一の例外は ScriptSock ディレクティブの
    追加で、このディレクティブは CGI デーモンとの通信用のソケットの名前を
    指定します。

    CGIDScriptTimeout ディレクティブ
    

    

    説明:The length of time to wait for more output from the
CGI program
    

    構文:CGIDScriptTimeout time[s|ms]
    

    デフォルト:value of Timeout directive when 
unset or set to 0
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    ステータス:Base
    

    モジュール:mod_cgid
    

    互換性:Available in httpd 2.4.10 and later; in prior releases no timeout was applied

    ScriptSock ディレクティブ
    

    

    説明:CGI デーモンとの通信に使われるソケットのファイル名の接頭辞
    

    構文:ScriptSock file-path
    

    デフォルト:ScriptSock logs/cgisock
    

    コンテキスト:サーバ設定ファイル
    

    ステータス:Base
    

    モジュール:mod_cgid
    

    
    
    このディレクティブは CGI デーモンとの通信に使われるソケットの
    ファイル名の接頭辞を設定します。また、ファイル名にはサーバのプロセスIDが
    追加されます。ソケットは Apache が起動されたユーザ (通常 root) の
    パーミッションを用いてオープンされます。CGI スクリプトとの通信の
    セキュリティを保つために、ソケットの存在するディレクトリに
    他のユーザが書き込み権限を持っていないようにすることが重要です。
    

    
    例
    
      ScriptSock /var/run/cgid.sock

    この日本語訳はすでに古くなっている
            可能性があります。
            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:ファイルの所有者に基づいた承認
    

    ステータス:Extension
    

    モジュール識別子:authz_owner_module
    

    ソースファイル:mod_authz_owner.c
    

    互換性:Apache 2.1 以降で使用可能
    

    概要
    

    
    このモジュールはリクエストされたファイルのファイルシステムの
    所有者やグループを HTTP 認証に使われたユーザ ID (ウェブユーザ ID) と
    比較することでアクセスを承認します。提供されたユーザ名とパスワードは
    mod_auth_basic や
    mod_auth_digest のような認証モジュールで既に
    適切に検証されている必要があります。mod_authz_owner
    は以下のように、Require ディレクティブの file-owner と
    file-group という二つの引数を認識します:
    

    
    
      
    file-owner
    
      
    提供されたウェブユーザ名はリクエストされたファイルの所有者の
      システムにおける名前と一致する必要があります。つまり、オペレーティング
      システムがファイルは jones により所有されている
      と言ったときは、ウェブからのアクセスに使われるユーザ名も
      jones でなければなりません。
    

      
    file-group
    
      
    ファイルを所有するシステムのグループの名前が、例えば
      mod_authz_groupfile や mod_authz_dbm
      により提供されるグループデータベースに存在していて、
      ウェブユーザ名がそのグループに属していなければなりません。
      例えば、オペレーティングシステムがファイルは (システムの) グループ
      accounts により所有されていると言ったときは、
      accounts がグループデータベースに存在して、
      リクエストに使用されたウェブユーザ名がそのグループに属している
      必要があります。
    
    
    

    
    注
    
      
    ファイルシステムに実際には存在しないリソース
      (つまり バーチャルなリソース) の承認に
      mod_authz_owner が使用されたときは、
      アクセスは拒否されます。
    

      
    特に、コンテント
      ネゴシエーションされた"MultiViews" のリソースは
      決して承認しません。

    設定例
    

    
    Require file-owner
    
      
    複数ユーザのシステムで Apache ウェブサーバが実行されていて、
      ~/public_html/private に各ユーザがファイルを置いているとします。
      AuthDBMUserFile
      データベースが一つだけあり、すべてのウェブユーザ名が列挙されており、
      このユーザ名がサーバで実際にファイルを所有しているユーザ名と一致している場合、
      次の節のような設定で、ユーザが自分自身のファイルにアクセスできるようになります。
      /home/smith/public_html/private の中のファイルは、所有者が
      smith の代わりに jones になっていない限り、
      jones にはアクセスは許可されません。
    

      
    
        <Directory /home/*/public_html/private>
    
        
          AuthType Basic
    
          AuthName MyPrivateFiles
    
          AuthBasicProvider dbm
    
          AuthDBMUserFile /usr/local/apache2/etc/.htdbm-all
    
          Require file-owner
    
            
        </Directory>
      
    
    

    
    Require file-group
    
      
    上記のようなシステムで、数人のユーザがプロジェクトのファイルを
      ~/public_html/project-foo で共有しているとします。
      ファイルはシステムのグループ foo に所有されていて、
      AuthDBMGroupFile
      データベースが一つだけあり、そこにすべてのウェブユーザ名と
      グループのメンバが列挙されている、つまり、それらの
      ユーザは少なくとも foo というグループに属している、とします。
      jones とsmith の二人共がグループ
      foo のメンバである場合、どちらの人も両方の
      project-foo にアクセスが許可されます。
    

      
    
        <Directory /home/*/public_html/project-foo>
    
        
          AuthType Basic
    
          AuthName "Project Foo Files"
    
          AuthBasicProvider dbm
    
          
    
          # combined user/group database
    
          AuthDBMUserFile  /usr/local/apache2/etc/.htdbm-all
    
          AuthDBMGroupFile /usr/local/apache2/etc/.htdbm-all
    
          
    
          Satisfy All
    
          Require file-group

    KeptBodySize Directive
    

    

    Description:Keep the request body instead of discarding it up to
the specified maximum size, for potential use by filters such as
mod_include.
    

    Syntax:KeptBodySize maximum size in bytes
    

    Default:KeptBodySize 0
    

    Context:directory
    

    Status:Base
    

    Module:mod_request
    

    
    
    Under normal circumstances, request handlers such as the
    default handler for static files will discard the request body
    when it is not needed by the request handler. As a result,
    filters such as mod_include are limited to making GET requests
    only when including other URLs as subrequests, even if the
    original request was a POST request, as the discarded
    request body is no longer available once filter processing is
    taking place.
    

    
    When this directive has a value greater than zero, request
    handlers that would otherwise discard request bodies will
    instead set the request body aside for use by filters up to
    the maximum size specified. In the case of the mod_include
    filter, an attempt to POST a request to the static
    shtml file will cause any subrequests to be POST
    requests, instead of GET requests as before.
    

    
    This feature makes it possible to break up complex web pages and
    web applications into small individual components, and combine
    the components and the surrounding web page structure together
    using mod_include. The components can take the
    form of CGI programs, scripted languages, or URLs reverse proxied
    into the URL space from another server using
    mod_proxy.
    

    
    Note: Each request set aside has to be set
    aside in temporary RAM until the request is complete. As a result,
    care should be taken to ensure sufficient RAM is available on the
    server to support the intended load. Use of this directive
    should be limited to where needed on targeted parts of your
    URL space, and with the lowest possible value that is still big
    enough to hold a request body.
    

    
    If the request size sent by the client exceeds the maximum
    size allocated by this directive, the server will return
    413 Request Entity Too Large.

    Description:Pass the response body through an external program before

    Summary
    

    
    mod_ext_filter presents a simple and familiar
    programming model for filters. With
    this module, a program which reads from stdin and writes to stdout
    (i.e., a Unix-style filter command) can be a filter for
    Apache. This filtering mechanism is much slower than using a
    filter which is specially written for the Apache API and runs
    inside of the Apache server process, but it does have the
    following benefits:
    

    
      
      
    • the programming model is much simpler
      • 

      
    • any programming/scripting language can be used, provided
      that it allows the program to read from standard input and
      write to standard output
      • 

      
    • existing programs can be used unmodified as Apache
      filters
      • 
    
    

    
    Even when the performance characteristics are not suitable
    for production use, mod_ext_filter can be used as
    a prototype environment for filters.

    Examples
    

    
    Generating HTML from some other type of response
    
      
    # mod_ext_filter directive to define a filter
# to HTML-ize text/c files using the external
# program /usr/bin/enscript, with the type of
# the result set to text/html
ExtFilterDefine c-to-html mode=output \
    intype=text/c outtype=text/html \
    cmd="/usr/bin/enscript --color -w html -Ec -o -"

<Directory "/export/home/trawick/apacheinst/htdocs/c">
    # core directive to cause the new filter to
    # be run on output
    SetOutputFilter c-to-html
    
    # mod_mime directive to set the type of .c
    # files to text/c
    AddType text/c .c
</Directory>
    

    

    
    Implementing a content encoding filter
    
      
    Note: this gzip example is just for the purposes of illustration.
      Please refer to mod_deflate for a practical
      implementation.
    

      
    # mod_ext_filter directive to define the external filter
ExtFilterDefine gzip mode=output cmd=/bin/gzip

<Location "/gzipped">
    
    # core directive to cause the gzip filter to be
    # run on output
    SetOutputFilter gzip
    
    # mod_headers directive to add
    # "Content-Encoding: gzip" header field
    Header set Content-Encoding gzip
</Location>
    

    

    
    Slowing down the server
    
      
    # mod_ext_filter directive to define a filter
# which runs everything through cat; cat doesn't
# modify anything; it just introduces extra pathlength
# and consumes more resources
ExtFilterDefine slowdown mode=output cmd=/bin/cat \
    preservescontentlength

<Location "/">
    # core directive to cause the slowdown filter to
    # be run several times on output
    #
    SetOutputFilter slowdown;slowdown;slowdown
</Location>
    

    

    
    Using sed to replace text in the response
    
      
    # mod_ext_filter directive to define a filter which
# replaces text in the response
#
ExtFilterDefine fixtext mode=output intype=text/html \
    cmd="/bin/sed s/verdana/arial/g"

<Location "/">
    # core directive to cause the fixtext filter to
    # be run on output
    SetOutputFilter fixtext
</Location>
    



    

    You can do the same thing using mod_substitute
without invoking an external process.
    

    
    

    
    Tracing another filter
    
      
    # Trace the data read and written by mod_deflate
# for a particular client (IP 192.168.1.31)
# experiencing compression problems.
# This filter will trace what goes into mod_deflate.
ExtFilterDefine tracebefore \
    cmd="/bin/tracefilter.pl /tmp/tracebefore" \
    EnableEnv=trace_this_client

# This filter will trace what goes after mod_deflate.
# Note that without the ftype parameter, the default
# filter type of AP_FTYPE_RESOURCE would cause the
# filter to be placed *before* mod_deflate in the filter
# chain.  Giving it a numeric value slightly higher than
# AP_FTYPE_CONTENT_SET will ensure that it is placed
# after mod_deflate.
ExtFilterDefine traceafter \
    cmd="/bin/tracefilter.pl /tmp/traceafter" \
    EnableEnv=trace_this_client ftype=21

<Directory "/usr/local/docs">
    SetEnvIf Remote_Addr 192.168.1.31 trace_this_client
    SetOutputFilter tracebefore;deflate;traceafter
</Directory>
    


      
    Here is the filter which traces the data:
    #!/usr/local/bin/perl -w
use strict;

open(SAVE, ">$ARGV[0]")
    or die "can't open $ARGV[0]: $?";

while (<STDIN>) {
    print SAVE $_;
    print $_;
}

close(SAVE);

    ExtFilterDefine Directive
    

    

    Description:Define an external filter
    

    Syntax:ExtFilterDefine filtername parameters
    

    Context:server config
    

    Status:Extension
    

    Module:mod_ext_filter
    

    
    
    The ExtFilterDefine directive defines the
    characteristics of an external filter, including the program to
    run and its arguments.
    

    
    filtername specifies the name of the filter being
    defined. This name can then be used in SetOutputFilter
    directives. It must be unique among all registered filters.
    At the present time, no error is reported by the
    register-filter API, so a problem with duplicate names isn't
    reported to the user.
    

    
    Subsequent parameters can appear in any order and define the
    external command to run and certain other characteristics. The
    only required parameter is cmd=. These parameters
    are:
    

    
    
      
    cmd=cmdline
    

      
    The cmd= keyword allows you to specify the
      external command to run. If there are arguments after the
      program name, the command line should be surrounded in
      quotation marks (e.g., cmd="/bin/mypgm
      arg1 arg2".) Normal shell quoting is
      not necessary since the program is run directly, bypassing the shell.
      Program arguments are blank-delimited. A backslash can be used to
      escape blanks which should be part of a program argument. Any
      backslashes which are part of the argument must be escaped with
      backslash themselves.  In addition to the standard CGI environment
      variables, DOCUMENT_URI, DOCUMENT_PATH_INFO, and
      QUERY_STRING_UNESCAPED will also be set for the program.
    

      
    mode=mode
    

      
    Use mode=output (the default) for filters which
      process the response.  Use mode=input for filters
      which process the request.  mode=input is available
      in Apache 2.1 and later.
    

      
    intype=imt
    

      
    This parameter specifies the internet media type (i.e.,
      MIME type) of documents which should be filtered. By default,
      all documents are filtered. If intype= is
      specified, the filter will be disabled for documents of other
      types.
    

      
    outtype=imt
    

      
    This parameter specifies the internet media type (i.e.,
      MIME type) of filtered documents. It is useful when the
      filter changes the internet media type as part of the
      filtering operation. By default, the internet media type is
      unchanged.
    

      
    PreservesContentLength
    

      
    The PreservesContentLength keyword specifies
      that the filter preserves the content length. This is not the
      default, as most filters change the content length. In the
      event that the filter doesn't modify the length, this keyword
      should be specified.
    

      
    ftype=filtertype
    

      
    This parameter specifies the numeric value for filter type
      that the filter should be registered as.  The default value,
      AP_FTYPE_RESOURCE, is sufficient in most cases.  If the filter
      needs to operate at a different point in the filter chain than
      resource filters, then this parameter will be necessary.  See
      the AP_FTYPE_foo definitions in util_filter.h for appropriate
      values.
    

      
    disableenv=env
    

      
    This parameter specifies the name of an environment variable
      which, if set, will disable the filter.
    

      
    enableenv=env
    

      
    This parameter specifies the name of an environment variable
      which must be set, or the filter will be disabled.

    ExtFilterOptions Directive
    

    

    Description:Configure mod_ext_filter options
    

    Syntax:ExtFilterOptions option [option] ...
    

    Default:ExtFilterOptions NoLogStderr
    

    Context:directory
    

    Status:Extension
    

    Module:mod_ext_filter
    

    
    
    The ExtFilterOptions directive specifies
    special processing options for mod_ext_filter.
    Option can be one of
    

    
    
      
    LogStderr | NoLogStderr
    

      
    The LogStderr keyword specifies that
      messages written to standard error by the external filter
      program will be saved in the Apache error log.
      NoLogStderr disables this feature.
    

      
    Onfail=[abort|remove]
    
      
    Determines how to proceed if the external filter program
      cannot be started.  With abort (the default value)
      the request will be aborted.  With remove, the
      filter is removed and the request continues without it.
    
    
    

    
    ExtFilterOptions LogStderr
    


    
    Messages written to the filter's standard error will be stored
    in the Apache error log.

    Apache Module mod_negotiation

    Description:Provides for content negotiation
    

    Status:Base
    

    Module Identifier:negotiation_module
    

    Source File:mod_negotiation.c
    

    Summary
    

    
    Content negotiation, or more accurately content selection, is
    the selection of the document that best matches the clients
    capabilities, from one of several available documents. There
    are two implementations of this.
    

    
      
      
    • A type map (a file with the handler
      type-map) which explicitly lists the files
      containing the variants.
      • 

      
    • A Multiviews search (enabled by the Multiviews
      Options), where the server does
      an implicit filename pattern match, and choose from amongst the
      results.
      • 
    
    

    


    top
    

    

    Type maps
    
    
    A type map has a format similar to RFC822 mail headers. It
    contains document descriptions separated by blank lines, with
    lines beginning with a hash character ('#') treated as
    comments. A document description consists of several header
    records; records may be continued on multiple lines if the
    continuation lines start with spaces. The leading space will be
    deleted and the lines concatenated. A header record consists of
    a keyword name, which always ends in a colon, followed by a
    value. Whitespace is allowed between the header name and value,
    and between the tokens of value. The headers allowed are: 
    

    
    
      
    Content-Encoding:
    
      
    The encoding of the file. Apache only recognizes
      encodings that are defined by an AddEncoding directive.
      This normally includes the encodings x-compress
      for compress'd files, and x-gzip for gzip'd
      files. The x- prefix is ignored for encoding
      comparisons.
    

      
    Content-Language:
    
      
    The language(s) of the variant, as an Internet standard
      language tag (RFC 1766). An example is en,
      meaning English. If the variant contains more than one
      language, they are separated by a comma.
    

      
    Content-Length:
    
      
    The length of the file, in bytes. If this header is not
      present, then the actual length of the file is used.
    

      
    Content-Type:
    

      
    
        The MIME media type of
        the document, with optional parameters. Parameters are
        separated from the media type and from one another by a
        semi-colon, with a syntax of name=value. Common
        parameters include:

        
    
          
    level
    
          
    an integer specifying the version of the media type.
          For text/html this defaults to 2, otherwise
          0.
    

          
    qs
    
          
    a floating-point number with a value in the range 0[.000]
          to 1[.000], indicating the relative 'quality' of this variant
          compared to the other available variants, independent of
          the client's capabilities. For example, a jpeg file is
          usually of higher source quality than an ascii file if it
          is attempting to represent a photograph. However, if the
          resource being represented is ascii art, then an ascii
          file would have a higher source quality than a jpeg file.
          All qs values are therefore specific to a given
          resource.
    
        
    

        
    Example
    
          Content-Type: image/jpeg; qs=0.8
        
    
      
    

      
    URI:
    
      
    uri of the file containing the variant (of the given
      media type, encoded with the given content encoding). These
      are interpreted as URLs relative to the map file; they must
      be on the same server, and they must refer to files to
      which the client would be granted access if they were to be
      requested directly.
    

      
    Body:
    
      
    The actual content of the resource may
      be included in the type-map file using the Body header.  This
      header must contain a string that designates a delimiter for
      the body content. Then all following lines in the type map
      file will be considered part of the resource body until the
      delimiter string is found.

      
    Example:
    
        Body:----xyz----
    
        <html>
    
        <body>
    
        <p>Content of the page.</p>
    
        </body>
    
        </html>
    
        ----xyz----
      
    
      
    
    
    

    
    Consider, for example, a resource called
    document.html which is available in English, French,
    and German. The files for each of these are called
    document.html.en, document.html.fr, and
    document.html.de, respectively. The type map file will
    be called document.html.var, and will contain the
    following:
    

    
    
    URI: document.html
    
    
    
    Content-language: en
    
    Content-type: text/html
    
    URI: document.html.en
    
    
    
    Content-language: fr
    
    Content-type: text/html
    
    URI: document.html.fr
    
    
    
    Content-language: de
    
    Content-type: text/html
    
    URI: document.html.de
    
    
    

    
    

    
    All four of these files should be placed in the same directory,
    and the .var file should be associated with the
    type-map handler with an AddHandler directive:
    

    
    AddHandler type-map .var
    


    
    A request for document.html.var in this directory will
    result in choosing the variant which most closely matches the language preference
    specified in the user's Accept-Language request
    header.
    

    
    If Multiviews is enabled, and MultiviewsMatch is set to "handlers" or "any",  a request to
    document.html will discover document.html.var and
    continue negotiating with the explicit type map.
    

    
    Other configuration directives, such as Alias can be used to map document.html to
    document.html.var.
    


    top
    

    

    Multiviews
    
    
    A Multiviews search is enabled by the Multiviews
    Options. If the server receives a
    request for /some/dir/foo and
    /some/dir/foo does not exist, then the
    server reads the directory looking for all files named
    foo.*, and effectively fakes up a type map which
    names all those files, assigning them the same media types and
    content-encodings it would have if the client had asked for one
    of them by name. It then chooses the best match to the client's
    requirements, and returns that document.
    

    
    The MultiviewsMatch
    directive configures whether Apache will consider files
    that do not have content negotiation meta-information assigned
    to them when choosing files.

    CacheNegotiatedDocs Directive
    

    

    Description:Allows content-negotiated documents to be
cached by proxy servers
    

    Syntax:CacheNegotiatedDocs On|Off
    

    Default:CacheNegotiatedDocs Off
    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_negotiation
    

    
    
    If set, this directive allows content-negotiated documents
    to be cached by proxy servers. This could mean that clients
    behind those proxys could retrieve versions of the documents
    that are not the best match for their abilities, but it will
    make caching more efficient.
    

    
    This directive only applies to requests which come from
    HTTP/1.0 browsers. HTTP/1.1 provides much better control over
    the caching of negotiated documents, and this directive has no
    effect in responses to HTTP/1.1 requests.
    



    

    top
    

    ForceLanguagePriority Directive
    

    

    Description:Action to take if a single acceptable document is not
found
    

    Syntax:ForceLanguagePriority None|Prefer|Fallback [Prefer|Fallback]
    

    Default:ForceLanguagePriority Prefer
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_negotiation
    

    
    
    The ForceLanguagePriority directive uses
    the given LanguagePriority to satisfy
    negotiation where the server could otherwise not return a single
    matching document.
    

    
    ForceLanguagePriority Prefer uses
    LanguagePriority to serve a one valid result, rather
    than returning an HTTP result 300 (MULTIPLE CHOICES) when there
    are several equally valid choices.  If the directives below were
    given, and the user's Accept-Language header assigned
    en and de each as quality .500
    (equally acceptable) then the first matching variant, en,
    will be served.
    

    
    LanguagePriority en fr de
ForceLanguagePriority Prefer
    


    
    ForceLanguagePriority Fallback uses
    LanguagePriority to
    serve a valid result, rather than returning an HTTP result 406
    (NOT ACCEPTABLE). If the directives below were given, and the user's
    Accept-Language only permitted an es
    language response, but such a variant isn't found, then the first
    variant from the LanguagePriority list below will be served.
    

    
    LanguagePriority en fr de
ForceLanguagePriority Fallback
    


    
    Both options, Prefer and Fallback, may be
    specified, so either the first matching variant from LanguagePriority will be served if
    more than one variant is acceptable, or first available document will
    be served if none of the variants matched the client's acceptable list
    of languages.

    LanguagePriority Directive
    

    

    Description:The precedence of language variants for cases where
the client does not express a preference
    

    Syntax:LanguagePriority MIME-lang [MIME-lang]
...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_negotiation
    

    
    
    The LanguagePriority sets the precedence
    of language variants for the case where the client does not
    express a preference, when handling a Multiviews request. The list
    of MIME-lang are in order of decreasing preference.
    

    
    LanguagePriority en fr de
    


    
    For a request for foo.html, where
    foo.html.fr and foo.html.de both
    existed, but the browser did not express a language preference,
    then foo.html.fr would be returned.
    

    
    Note that this directive only has an effect if a 'best'
    language cannot be determined by any other means or the ForceLanguagePriority directive
    is not None. In general, the client determines the
    language preference, not the server.

    Apache MPM worker

    Açıklama:Çok evreli ve çok süreçli melez bir HTTP sunucusu oluşturan çok
süreçlilik modülü.
    

    Durum:MPM
    

    Modül Betimleyici:mpm_worker_module
    

    Kaynak Dosyası:worker.c
    

    Özet
    

    
    Bu çok süreçlilik modülü (MPM) hem çok süreçli hem de çok evreli
      olabilen melez bir sunucu oluşturur. İstekleri sunmak için evreleri
      kullanması sebebiyle çok süreçli bir sunucudan daha az sistem kaynağı
      harcayarak daha çok isteğe hizmet sunabilir. Bununla birlikte, herbiri
      çok sayıda evreye sahip çok sayıda süreci canlı tutarak bir çok süreçli
      sunucu kadar kararlı olur.
    

    
    Bu MPM’i denetim altında tutmakta kullanılan en önemli yönergeler, her
      çocuk süreç için konuşlandırılacak evre sayısını belirleyen ThreadsPerChild yönergesi ile devreye
      sokulacak toplam evre sayısının azamisini belirleyen MaxRequestWorkers yönergesidir.
    

    


    top
    

    

    Nasıl çalışır?
    
    
    Çocuk süreçleri devreye almaktan tek bir süreç (ana süreç) sorumludur.
      Her çocuk süreç ThreadsPerChild yönergesinde belirtilen sayıda evre
      konuşlandırır. Bunlardan ayrı olarak, bir dinleyici evre bağlantıları
      dinleyip gelenleri işlenmek üzere bu sunucu evrelerinden birine
      aktarır.
    

    
    Apache HTTP Sunucusu daima, gelen isteklere hizmet sunmaya hazır
      yedek
      veya boştaki sunucu evrelerinden oluşan bir havuzu canlı tutmaya
      çalışır. Bu suretle, istemcilere isteklerinin sunulması için yeni çocuk
      süreçlerin çatallanmasını, dolayısıyla yeni evrelerin
      konuşlandırılmasını beklemek gerekmez. Başlangıçta çalıştırılacak çocuk
      süreçlerin sayısı StartServers yönergesinde belirtilir.
      Apache httpd, çalışma süresi boyunca MinSpareThreads ve MaxSpareThreads yönergeleri ile belirtilen sınırlar
      dahilinde kalmak üzere gerektiğinde süreçleri öldürerek gerektiğinde
      yenilerini devreye alarak tüm süreçlerdeki toplam evre sayısını sabit
      tutmaya çalışır. Bu işlem kendiliğinden çok iyi yürüdüğünden bu
      yönergelere öntanımlı değerlerinden farklı değerlerin atanması nadiren
      gerekli olur. Aynı anda hizmet sunulabilecek istemcilerin sayısı (yani,
      tüm süreçlerin toplam evre sayısı) MaxRequestWorkers yönergesi ile belirlenir. Etkin çocuk
      süreçlerin sayısı ise MaxRequestWorkers yönergesindeki değerin ThreadsPerChild yönergesindeki değere
      bölünmesi ile elde edilir.
    

    
    Bu iki yönerge aynı anda etkin olabilecek çocuk süreçlerin ve her
      çocuk süreçteki sunucu evreleri sayısının üst sınırını belirler ve bu
      sınır sadece ana sunucu tamamen durdurulup yeniden başlatılarak
      değiştirilebilir. ServerLimit yönergesinin değeri etkin çocuk süreç
      sayısının üst sınırı olup MaxRequestWorkers yönergesindeki değerin ThreadsPerChild yönergesindeki değere
      bölünmesi ile elde değere eşit veya bundan küçük olması gerekir.
      ThreadLimit yönergesinin
      değeri ise sunucu evreleri sayısının üst sınırını belirler ve ThreadsPerChild yönergesindeki değerden
      büyük veya ona eşit olması gerekir.
    

    
    Sonlandırma sırasında etkin çocuk süreçlere ek olarak mevcut istemci
      bağlantılarını işleme sokmaya çalışan tek bir sunucu evresinden başka
      fazladan bir çocuk süreç etkin kalabileceği gibi sonlandırılacak süreç
      sayısının en fazla MaxRequestWorkers olması gerekirse de gerçekte sayı bundan
      küçük olabilir.  Şöyle bir işlemle tek bir çocuk sürecin sonlandırılması
      iptal edilerek bu gibi durumlara karşı önlem alınabilir:
    

    

    
    worker modülünün öntanımlı süreç-evre yapılandırması
      genelde şöyledir:
    

    
    ServerLimit         16
StartServers         2
MaxRequestWorkers  150
MinSpareThreads     25
MaxSpareThreads     75
ThreadsPerChild     25
    


    
    Unix altında 80. portu dinleyebilmek için ana sürecin root tarafından
      çalıştırılmış olması gerekirse de çocuk süreçler ve evreler Apache
      httpd tarafından daha az yetkili bir kullanıcının aidiyetinde
      çalıştırılırlar. Apache httpd’nin çocuk süreçlerinin kullanıcı ve
      gruplarını ayarlamak için User
      ve Group yönergeleri
      kullanılır.
      Çocuk süreçlerin sunacakları içeriği okumaya yetkili olmaları gerekir,
      fakat bu yetkinin mümkün olduğunca kısıtlı tutulmasına çalışılmalıdır.
      Bundan başka, suexec kullanılmadığı takdirde, bu
      yönergeler CGI betikleri tarafından miras alınacak yetkili kullanıcı
      ve grubu da ayarlarlar.
    

    
    MaxConnectionsPerChild
      yönergesi ana sunucunun eski süreçleri öldürüp yenilerini oluşturmayı
      ne kadar sıklıkla yapacağını denetler.
    

    
    Bu MPM, gürleyen sürü sorunu ortaya çıktığında (genelde çok sayıda
      dinlenen soket varlığında) gelen bağlantılara erişimi dizgileştirmek için
      mpm-accept muteksini kullanır. Bu muteksin gerçeklenimle
      ilgili hususları Mutex yönergesi ile
      yapılandırılabilir. Bu muteks hakkında ek bilgi  için başarımın arttırılması
      belgesine bakınız.

    Sommaire
    

    
    mod_dumpio permet d'enregistrer toutes les entrées
    reçues par Apache et/ou toutes les sorties envoyées par ce dernier
    dans le fichier error.log.
    
    

    
    L'enregistrement des données s'effectue juste après le décodage
    SSL (pour les entrées), et juste avant le codage SSL (pour les
    sorties). Comme on peut s'y attendre, tout ceci peut représenter un
    volume important de données, et ne doit être utilisé qu'à des fins
    de débogage.

    Description:mod_proxy extension for
CONNECT request handling
    

    Status:Extension
    

    Module Identifier:proxy_connect_module
    

    Source File:mod_proxy_connect.c
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the CONNECT
    HTTP method. This method is mainly used to tunnel SSL requests
    through proxy servers.
    

    
    Thus, in order to get the ability of handling CONNECT
    requests, mod_proxy and
    mod_proxy_connect have to be present in the server.
    

    
    CONNECT is also used when the server needs to send an HTTPS request
    through a forward proxy. In this case the server acts as a CONNECT client.
    This functionality is part of mod_proxy and
    mod_proxy_connect is not needed in this case.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.

    Request notes
    
    
    mod_proxy_connect creates the following request notes for
        logging using the %{VARNAME}n format in
        LogFormat or
        ErrorLogFormat:
    
    
    
    
        
    proxy-source-port
    
        
    The local port used for the connection to the backend server.

    AllowCONNECT Directive
    

    

    Description:Ports that are allowed to CONNECT through the
proxy
    

    Syntax:AllowCONNECT port[-port]
[port[-port]] ...
    

    Default:AllowCONNECT 443 563
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy_connect
    

    Compatibility:Moved from mod_proxy in Apache 2.3.5.
Port ranges available since Apache 2.3.7.
    

    
    
    The AllowCONNECT directive specifies a list
    of port numbers or ranges to which the proxy CONNECT method
    may connect.  Today's browsers use this method when a https
    connection is requested and proxy tunneling over HTTP is in effect.
    

    
    By default, only the default https port (443) and the
    default snews port (563) are enabled. Use the
    AllowCONNECT directive to override this default and
    allow connections to the listed ports only.

    Module Apache mod_mime_magic
    

    

    Langues Disponibles:  en  |

    Description:Détermine le type MIME d'un fichier à partir de quelques
octets de son contenu
    

    Statut:Extension
    

    Identificateur de Module:mime_magic_module
    

    Fichier Source:mod_mime_magic.c
    

    Sommaire
    

    
    Ce module permet de déterminer le type
    MIME des fichiers de la même manière que la commande Unix
    file(1), à savoir en se basant sur les premiers octets
    du fichier. Il est conçu comme une "seconde ligne de défense" pour
    les cas où mod_mime ne parvient pas à déterminer le
    type du fichier.
    

    
    Ce module est dérivé d'une version libre de la commande Unix
    file(1) qui utilise des "nombres magiques" et autres
    marques distinctives issus du contenu du fichier pour essayer de
    déterminer le type de contenu. Ce module n'est activé que si le
    fichier magique est spécifié par la directive MimeMagicFile.
    

    


    top
    

    

    Format du fichier magique
    

    
    Le fichier contient du texte ASCII sur 4 à 5 colonnes. Les lignes
    vides sont autorisées mais ignorées. Toute ligne commençant par un
    dièse (#) est un commentaire. Les autres lignes sont
    interprétées en colonnes comme suit :
    

    
    ColonneDescription
    

    1
        numéro de l'octet à partir duquel la vérification débute
    
         ">" indique une dépendance par rapport à la
	 dernière ligne non-">"

    4
        type MIME si correspondance
    

    5
        codage MIME si correspondance (optionnel)
    

    

    
    Par exemple, les lignes du fichier magique suivantes
    permettraient de reconnaître certains formats audio :
    

    
    # Sun/NeXT audio data
0      string      .snd
>12    belong      1       audio/basic
>12    belong      2       audio/basic
>12    belong      3       audio/basic
>12    belong      4       audio/basic
>12    belong      5       audio/basic
>12    belong      6       audio/basic
>12    belong      7       audio/basic
>12    belong     23       audio/x-adpcm
    

    
    Et celles-ci permettraient de reconnaître la différence entre les
    fichiers *.doc qui contiennent des documents Microsoft
    Word et les documents FrameMaker (ce sont des formats de fichiers
    incompatibles qui possèdent le même suffixe).
    

    
    # Frame
0  string  \<MakerFile        application/x-frame
0  string  \<MIFFile          application/x-frame
0  string  \<MakerDictionary  application/x-frame
0  string  \<MakerScreenFon   application/x-frame
0  string  \<MML              application/x-frame
0  string  \<Book             application/x-frame
0  string  \<Maker            application/x-frame

# MS-Word
0  string  \376\067\0\043            application/msword
0  string  \320\317\021\340\241\261  application/msword
0  string  \333\245-\0\0\0           application/msword
    

    
    Un champ optionnel codage MIME peut être ajouté dans la cinquième
    colonne. Par exemple, cette ligne permet de reconnaître les fichiers
    compressés par gzip et définissent le type de codage.
    

    
    # gzip (GNU zip, à ne pas confondre avec
#       l'archiveur zip [Info-ZIP/PKWARE])

0  string  \037\213  application/octet-stream  x-gzip

    Problèmes liés aux performances
    
    
    Ce module n'est pas fait pour tous les systèmes. Si votre système
    parvient à peine à supporter sa charge, ou si vous testez les
    performances d'un serveur web, il est déconseillé d'utiliser ce
    module car son fonctionnement a un prix en matière de ressources
    consommées.
    

    
    Des efforts ont cependant été fournis pour améliorer les
    performances du code original de la commande file(1) en
    l'adaptant pour fonctionner sur un serveur web à forte charge. Il a
    été conçu pour un serveur sur lequel des milliers d'utilisateurs
    publient leurs propres documents, ce qui est probablement très
    courant sur un intranet. Il s'avère souvent bénéfique qu'un serveur
    puisse prendre des décisions plus pertinentes à propos du contenu
    d'un fichier que celles se basant sur le nom du fichier seul, ne
    serait-ce que pour diminuer le nombre d'appels du type "pourquoi ma
    page ne s'affiche-t-elle pas ?" survenant lorsque les utilisateurs
    nomment leurs fichiers incorrectement. Vous devez déterminer si la
    charge supplémentaire convient à votre environnement.

    Description:Customization of HTTP request and response
headers
    

    Status:Extension
    

    Module Identifier:headers_module
    

    Source File:mod_headers.c
    

    Summary
    

    
    This module provides directives to control and modify HTTP
    request and response headers. Headers can be merged, replaced
    or removed.
    

    


    top
    

    

    Order of Processing
    

    
    The directives provided by mod_headers can
    occur almost anywhere within the server configuration, and can be
    limited in scope by enclosing them in configuration sections.
    

    
    Order of processing is important and is affected both by the
    order in the configuration file and by placement in configuration sections. These
    two directives have a different effect if reversed:
    

    
    RequestHeader append MirrorID "mirror 12"
RequestHeader unset MirrorID
    


    
    This way round, the MirrorID header is not set. If
    reversed, the MirrorID header is set to "mirror 12".
    

    top
    

    

    Early and Late Processing
    
    
    mod_headers can be applied either early or late
    in the request.  The normal mode is late, when Request Headers are
    set immediately before running the content generator and Response
    Headers just as the response is sent down the wire.  Always use
    Late mode in an operational server.
    

    
    Early mode is designed as a test/debugging aid for developers.
    Directives defined using the early keyword are set
    right at the beginning of processing the request.  This means
    they can be used to simulate different requests and set up test
    cases, but it also means that headers may be changed at any time
    by other modules before generating a Response.
    

    
    Because early directives are processed before the request path's
    configuration is traversed, early headers can only be set in a
    main server or virtual host context.  Early directives cannot depend
    on a request path, so they will fail in contexts such as
    <Directory> or
    <Location>.
    

    top
    

    

    Examples
    

    
      
      
    1. 
        Copy all request headers that begin with "TS" to the
        response headers:

        
      Header echo ^TS
      

      
      2. 

      
    2. 
        Add a header, MyHeader, to the response including a
        timestamp for when the request was received and how long it
        took to begin serving the request. This header can be used by
        the client to intuit load on the server or in isolating
        bottlenecks between the client and the server.

        
      Header set MyHeader "%D %t"
      


        
      results in this header being added to the response:
      

        
      
          MyHeader: D=3775428 t=991424704447256
        
      
      
      3. 

      
    3. 
        Say hello to Joe

        
      Header set MyHeader "Hello Joe. It took %D microseconds for Apache to serve this request."
      


        
      results in this header being added to the response:
      

        
      
          MyHeader: Hello Joe. It took D=3775428 microseconds for Apache
          to serve this request.
        
      
      
      4. 

      
    4. 
        Conditionally send MyHeader on the response if and
        only if header MyRequestHeader is present on the request.
        This is useful for constructing headers in response to some client
        stimulus. Note that this example requires the services of the
        mod_setenvif module.

        
      SetEnvIf MyRequestHeader myvalue HAVE_MyRequestHeader
Header set MyHeader "%D %t mytext" env=HAVE_MyRequestHeader
      


        
      If the header MyRequestHeader: myvalue is present on
        the HTTP request, the response will contain the following header:
      

        
      
          MyHeader: D=3775428 t=991424704447256 mytext
        
      
      
      5. 

      
    5. 
        Enable DAV to work with Apache running HTTP through SSL hardware
        (problem
        description) by replacing https: with
        http: in the Destination header:

        
      RequestHeader edit Destination ^https: http: early
      

      
      6. 

      
    6. 
        Set the same header value under multiple nonexclusive conditions,
        but do not duplicate the value in the final header.
        If all of the following conditions applied to a request (i.e.,
        if the CGI, NO_CACHE and
        NO_STORE environment variables all existed for the
        request):

        
      Header merge Cache-Control no-cache env=CGI
Header merge Cache-Control no-cache env=NO_CACHE
Header merge Cache-Control no-store env=NO_STORE
      


        
      then the response would contain the following header:
      

        
      
          Cache-Control: no-cache, no-store
        
      

        
      If append was used instead of merge,
        then the response would contain the following header:
      

        
      
          Cache-Control: no-cache, no-cache, no-store

        Set a test cookie if and only if the client didn't send us a cookie

    Header Directive
    

    

    Description:Configure HTTP response headers
    

    Syntax:Header [condition] add|append|echo|edit|edit*|merge|set|setifempty|unset|note
header [[expr=]value [replacement]
[early|env=[!]varname|expr=expression]]

    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Extension

    Compatibility:SetIfEmpty available in 2.4.7 and later, expr=value
available in 2.4.10 and later
    

    
    
    This directive can replace, merge or remove HTTP response
    headers. The header is modified just after the content handler
    and output filters are run, allowing outgoing headers to be
    modified.
    

    
     The optional condition argument determines which internal
    table of responses headers this directive will operate against:
    onsuccess (default, can be omitted) or always.
    The difference between the two lists is that the headers contained in the
    latter are added to the response even on error, and persisted across
    internal redirects (for example, ErrorDocument handlers).

    Note also that repeating this directive with both conditions makes sense in
    some scenarios because always is not a superset of
    onsuccess with respect to existing headers:
    

    
      
       
    •  You're adding a header to a locally generated non-success (non-2xx) response, such
            as a redirect, in which case only the table corresponding to
            always is used in the ultimate response.
      • 
       
    •  You're modifying or removing a header generated by a CGI script
            or by mod_proxy_fcgi,
            in which case the CGI scripts' headers are in the table corresponding to
            always and not in the default table.
      • 
       
    •  You're modifying or removing a header generated by some piece of
            the server but that header is not being found by the default
            onsuccess condition.
      • 
    
    

    
    This difference between onsuccess and always is
    a feature that resulted as a consequence of how httpd internally stores
    headers for a HTTP response, since it does not offer any "normalized" single
    list of headers. The main problem that can arise if the following concept
    is not kept in mind while writing the configuration is that some HTTP responses
    might end up with the same header duplicated (confusing users or sometimes even
    HTTP clients). For example, suppose that you have a simple PHP proxy setup with
    mod_proxy_fcgi and your backend PHP scripts adds the
    X-Foo: bar header to each HTTP response. As described above,
    mod_proxy_fcgi uses the always table to store
    headers, so a configuration like the following ends up in the wrong result, namely
    having the header duplicated with both values:
    

    
    # X-Foo's value is set in the 'onsuccess' headers table
Header set X-Foo: baz
    
    

    
    To circumvent this limitation, there are some known configuration
    patterns that can help, like the following:
    

        
    # 'onsuccess' can be omitted since it is the default
Header onsuccess unset X-Foo
Header always set X-Foo "baz"
    


    
    Separately from the condition parameter described above, you
    can limit an action based on HTTP status codes for e.g. proxied or CGI
    requests. See the example that uses %{REQUEST_STATUS} in the section above.
    

    
    The action it performs is determined by the first
    argument (second argument if a condition is specified).
    This can be one of the following values:
    

    
    Warning
    
        
    Please read the difference between always
        and onsuccess headers list described above
        before start reading the actions list, since that important
        concept still applies. Each action, in fact, works as described
        but only on the target headers list.
    
    
    

    
    
    
    add
    
    
    The response header is added to the existing set of headers,
    even if this header already exists. This can result in two
    (or more) headers having the same name. This can lead to
    unforeseen consequences, and in general set,
    append or merge should be used instead.
    

    
    append
    
    
    The response header is appended to any existing header of
    the same name. When a new value is merged onto an existing
    header it is separated from the existing header with a comma.
    This is the HTTP standard way of giving a header multiple values.
    

    
    echo
    
    
    Request headers with this name are echoed back in the
    response headers. header may be a
    regular expression.
    value must be omitted.
    

    
    edit
    
    
    edit*
    
    
    If this response header exists, its value is transformed according
    to a regular expression
    search-and-replace.  The value argument is a regular expression, and the replacement
    is a replacement string, which may contain backreferences or format specifiers.
    The edit form will match and replace exactly once
    in a header value, whereas the edit* form will replace
    every instance of the search pattern if it appears more
    than once.
    

    
    merge
    
    
    The response header is appended to any existing header of
    the same name, unless the value to be appended already appears in the
    header's comma-delimited list of values.  When a new value is merged onto
    an existing header it is separated from the existing header with a comma.
    This is the HTTP standard way of giving a header multiple values.
    Values are compared in a case sensitive manner, and after
    all format specifiers have been processed.  Values in double quotes
    are considered different from otherwise identical unquoted values.
    

    
    set
    
    
    The response header is set, replacing any previous header
    with this name. The value may be a format string.
    

    
    setifempty
    
    
    The request header is set, but only if there is no previous header
    with this name.
    
    
    The Content-Type header is a special use case since there might be
    the chance that its value have been determined but the header is not part
    of the response when setifempty is evaluated.
    It is safer to use set for this use case like in the
    following example:
    
    Header set Content-Type "text/plain" "expr=-z %{CONTENT_TYPE}"
    

    
    

    
    unset
    
    
    The response header of this name is removed, if it exists.
    If there are multiple headers of the same name, all will be
    removed. value must be omitted.
    

    
    note
    
    
    The value of the named response header is copied into an
    internal note whose name is given by value.  This is useful
    if a header sent by a CGI or proxied resource is configured to be unset
    but should also be logged.
    
    Available in 2.4.7 and later.
    

    
    

    
    This argument is followed by a header name, which
    can include the final colon, but it is not required. Case is
    ignored for set, append, merge,
    add, unset and edit.
    The header name for echo
    is case sensitive and may be a regular
    expression.
    

    
    For set, append, merge and
    add a value is specified as the next argument.
    If value
    contains spaces, it should be surrounded by double quotes.
    value may be a character string, a string containing
    mod_headers specific format specifiers (and character
    literals), or an ap_expr expression prefixed
    with expr=
    

    
     The following format specifiers are supported in value:
    

    
    FormatDescription
    

    %%
        The percent sign
    

    %t
        The time the request was received in Universal Coordinated Time
        since the epoch (Jan. 1, 1970) measured in microseconds. The value
        is preceded by t=.
    

    %D
        The time from when the request was received to the time the
        headers are sent on the wire. This is a measure of the duration
        of the request. The value is preceded by D=.
        The value is measured in microseconds.
    

    %l
        The current load averages of the actual server itself. It is
        designed to expose the values obtained by getloadavg()
        and this represents the current load average, the 5 minute average, and
        the 15 minute average. The value is preceded by l= with each
        average separated by /.
    
        Available in 2.4.4 and later.
        
    

    %i
        The current idle percentage of httpd (0 to 100) based on available
        processes and threads. The value is preceded by i=.
    
        Available in 2.4.4 and later.
        
    

    %b
        The current busy percentage of httpd (0 to 100) based on available
        processes and threads. The value is preceded by b=.
    
        Available in 2.4.4 and later.
        
    

    %{VARNAME}e
        The contents of the environment
        variable VARNAME.
    

    %{VARNAME}s
        The contents of the SSL environment
        variable VARNAME, if mod_ssl is enabled.
    

    

    
    Note
    
      
    The %s format specifier is only available in
      Apache 2.1 and later; it can be used instead of %e
      to avoid the overhead of enabling SSLOptions
      +StdEnvVars.  If SSLOptions +StdEnvVars must
      be enabled anyway for some other reason, %e will be
      more efficient than %s.
    
    
    

    
    Note on expression values
    
    
     When the value parameter uses the ap_expr
    parser, some expression syntax will differ from examples that evaluate
    boolean expressions such as <If>:
    
    
      
      
    • The starting point of the grammar is 'string' rather than 'expr'.
      • 
      
    • Function calls use the %{funcname:arg} syntax rather than
          funcname(arg).
      • 
      
    • Multi-argument functions are not currently accessible from this
          starting point
      • 
      
    • Quote the entire parameter, such as
          
      Header set foo-checksum "expr=%{md5:foo}"
      

       
      • 

    
    
    
    

    
    For edit there is both a value argument
    which is a regular expression,
    and an additional replacement string. As of version 2.4.7
    the replacement string may also contain format specifiers.
    

    
    The Header directive may be followed by
    an additional argument, which may be any of:
    
    
    
    
    early
    
    
    Specifies early processing.
    
    
    env=[!]varname
    
    
    The directive is applied if and only if the environment variable varname exists.
        A ! in front of varname reverses the test,
        so the directive applies only if varname is unset.
    
    
    expr=expression
    
    
    The directive is applied if and only if expression
        evaluates to true. Details of expression syntax and evaluation are
        documented in the ap_expr documentation.
        
    # This delays the evaluation of the condition clause compared to <If>
Header always set CustomHeader my-value "expr=%{REQUEST_URI} =~ m#^/special_path.php$#"
    

        
    
    
    

    
    Except in early mode, the
    Header directives are processed just
    before the response is sent to the network. This means that it is
    possible to set and/or override most headers, except for some headers
    added by the HTTP header filter.  Prior to 2.2.12, it was not possible
    to change the Content-Type header with this directive.

    This directive can replace, merge, change or remove HTTP request
    headers. The header is modified just before the content handler
    is run, allowing incoming headers to be modified. The action it
    performs is determined by the first argument. This can be one
    of the following values:
    

    
    

    
    add
    
    
    The request header is added to the existing set of headers,
    even if this header already exists. This can result in two
    (or more) headers having the same name. This can lead to
    unforeseen consequences, and in general set,
    append or merge should be used instead.
    

    
    append
    
    
    The request header is appended to any existing header of the
    same name. When a new value is merged onto an existing header
    it is separated from the existing header with a comma. This
    is the HTTP standard way of giving a header multiple
    values.
    

    
    edit
    
    
    edit*
    
    
    If this request header exists, its value is transformed according
    to a regular expression
    search-and-replace.  The value argument is a regular expression, and the replacement
    is a replacement string, which may contain backreferences or format specifiers.
    The edit form will match and replace exactly once
    in a header value, whereas the edit* form will replace
    every instance of the search pattern if it appears more
    than once.
    

    
    merge
    
    
    The request header is appended to any existing header of
    the same name, unless the value to be appended already appears in the
    existing header's comma-delimited list of values.  When a new value is
    merged onto an existing header it is separated from the existing header
    with a comma.  This is the HTTP standard way of giving a header multiple
    values.  Values are compared in a case sensitive manner, and after
    all format specifiers have been processed.  Values in double quotes
    are considered different from otherwise identical unquoted values.
    

    
    set
    
    
    The request header is set, replacing any previous header
    with this name
    

    
    setifempty
    
    
    The request header is set, but only if there is no previous header
    with this name.
    
    Available in 2.4.7 and later.
    

    
    unset
    
    
    The request header of this name is removed, if it exists. If
    there are multiple headers of the same name, all will be removed.
    value must be omitted.
    
    
    

    
    This argument is followed by a header name, which can
    include the final colon, but it is not required. Case is
    ignored. For set, append, merge and
    add a value is given as the third argument. If a
    value contains spaces, it should be surrounded by double
    quotes. For unset, no value should be given.
    value may be a character string, a string containing format
    specifiers or a combination of both. The supported format specifiers
    are the same as for the Header,
    please have a look there for details.  For edit both
    a value and a replacement are required, and are
    a regular expression and a
    replacement string respectively.
    

    
    The RequestHeader directive may be followed by
    an additional argument, which may be any of:
    
    
    
    
    early
    
    
    Specifies early processing.
    
    
    env=[!]varname
    
    
    The directive is applied if and only if the environment variable varname exists.
        A ! in front of varname reverses the test,
        so the directive applies only if varname is unset.
    
    
    expr=expression
    
    
    The directive is applied if and only if expression
        evaluates to true. Details of expression syntax and evaluation are
        documented in the ap_expr documentation.
    
    
    

    
    Except in early mode, the
    RequestHeader directive is processed
    just before the request is run by its handler in the fixup phase.
    This should allow headers generated by the browser, or by Apache
    input filters to be overridden or modified.

    Apache Module mod_socache_memcache
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Memcache based shared object cache provider.
    

    Status:Extension
    

    Module Identifier:socache_memcache_module
    

    Source File:mod_socache_memcache.c
    

    Summary
    

    
    mod_socache_memcache is a shared object cache provider
    which provides for creation and access to a cache backed by the
    memcached
    high-performance, distributed memory object caching system.
    
    

 
    
    This shared object cache provider's "create" method requires a 
       comma separated list of memcached host/port specifications. If using
       this provider via another modules configuration (such as 
       SSLSessionCache), provide
       the list of servers as the optional "arg" parameter.
    

     
    SSLSessionCache memcache:memcache.example.com:12345,memcache2.example.com:12345
    

      
    
    Details of other shared object cache providers can be found
    here.

    MemcacheConnTTL Directive
    

    

    Description:Keepalive time for idle connections
    

    Syntax:MemcacheConnTTL num[units]
    

    Default:MemcacheConnTTL 15s
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_socache_memcache
    

    Compatibility:Available in Apache 2.4.17 and later
    

    

    
    Set the time to keep idle connections with the memcache server(s)
    alive (threaded platforms only).
    
    
    
    Valid values for MemcacheConnTTL are times
    up to one hour. 0 means no timeout.
    

    
    This timeout defaults to units of seconds, but accepts
    suffixes for milliseconds (ms), seconds (s), minutes (min), and hours (h).
    
    

    
    Before Apache 2.4.17, this timeout was hardcoded and its value was 600 usec.
    So, the closest configuration to match the legacy behaviour is to set
    MemcacheConnTTL to 1ms.
    

    
    # Set a timeout of 10 minutes
MemcacheConnTTL 10min
# Set a timeout of 60 seconds
MemcacheConnTTL 60

Override Class Index for .htaccess - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Override Class Index for .htaccess
    

    

    Available Languages:  en  |
 fr 
    

    

    
    
      This is an index of the directives that are allowed in .htaccess files for
      various AllowOverride settings,
      organized by class. Its intended purpose is to help server administrators
      verify the privileges they're granting to .htaccess users. For an overview
      of how .htaccess works, see the
      .htaccess tutorial.
    
    

    
    
      To determine the set of directives that your server configuration allows
      .htaccess users to use:
    
    

    
      
      
    1. Start with the set of directives in the AllowOverrideList
      for the directory in question. (By default, this is set to
      None.)
      2. 
      
    2. Find the AllowOverride setting for the directory in
      question. (By default, it is set to None.) There are two
      special cases:
        
        
          
      1. If your AllowOverride setting is All,
          add every directive listed on this page to the list.
        2. 
          
      2. If your AllowOverride setting is None,
          you're done. Only the directives in the AllowOverrideList
          (if any) will be allowed.
        3. 
        
      
      
      3. 
      
    3. For each override class listed in AllowOverride, look up
      the corresponding set of directives below and add them to the list.
      4. 
      
    4. Finally, add the set of directives that is always allowed in
      .htaccess (these are listed in the
      All section, below).
      5. 
    
    

    
    
      Several of the override classes are quite powerful and give .htaccess
      users a large amount of control over the server. For a stricter approach,
      set AllowOverride None and use
      AllowOverrideList to specify the
      exact list of directives that .htaccess users are allowed to use.

    All

mod_authz_dbm - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4
    

    

    <-
    


    

    Apache Module mod_authz_dbm
    

    

    Available Languages:  en  |

 ko 
    

    

    Description:Group authorization using DBM files
    

    Status:Extension
    

    Module Identifier:authz_dbm_module
    

    Source File:mod_authz_dbm.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module provides authorization capabilities so that
       authenticated users can be allowed or denied access to portions
       of the web site by group membership. Similar functionality is
       provided by mod_authz_groupfile.
    

    


    top
    

    

    The Require Directives
    

    
    Apache's Require
    directives are used during the authorization phase to ensure that
    a user is allowed to access a resource.  mod_authz_dbm extends the
    authorization types with dbm-group.
    

    
    Since v2.4.8, expressions are supported
    within the DBM require directives.
    


    Require dbm-group
    

    
    This directive specifies group membership that is required for the
    user to gain access.
    

    
    Require dbm-group admin
    





    Require dbm-file-group
    

    
    When this directive is specified, the user must be a member of the group
    assigned to the file being accessed.
    

    
    Require dbm-file-group
    





    top
    

    

    Example usage
    


    Note that using mod_authz_dbm requires you to require dbm-group
instead of group:

    

    <Directory "/foo/bar">
  AuthType Basic
  AuthName "Secure Area"
  AuthBasicProvider dbm
  AuthDBMUserFile "site/data/users"
  AuthDBMGroupFile "site/data/users"
  Require dbm-group admin
</Directory>
    


    

    top
    

    AuthDBMGroupFile Directive
    

    

    Description:Sets the name of the database file containing the list
of user groups for authorization
    

    Syntax:AuthDBMGroupFile file-path
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authz_dbm
    

    
    
    The AuthDBMGroupFile directive sets the
    name of a DBM file containing the list of user groups for user
    authorization.  File-path is the absolute path to the
    group file.
    

    
    The group file is keyed on the username. The value for a
    user is a comma-separated list of the groups to which the users
    belongs. There must be no whitespace within the value, and it
    must never contain any colons.
    

    
    Security
    
      
    Make sure that the AuthDBMGroupFile is
      stored outside the document tree of the web-server. Do
      not put it in the directory that it protects.
      Otherwise, clients will be able to download the
      AuthDBMGroupFile unless otherwise
      protected.
    
    
    

    
    Combining Group and Password DBM files: In some cases it is
    easier to manage a single database which contains both the
    password and group details for each user. This simplifies any
    support programs that need to be written: they now only have to
    deal with writing to and locking a single DBM file. This can be
    accomplished by first setting the group and password files to
    point to the same DBM:
    

    
    AuthDBMGroupFile "/www/userbase"
AuthDBMUserFile "/www/userbase"
    


    
    The key for the single DBM is the username. The value consists
    of
    

    
    
      Encrypted Password : List of Groups [ : (ignored) ]
    
    

    
    The password section contains the encrypted
    password as before. This is followed by a colon and the comma
    separated list of groups. Other data may optionally be left in the
    DBM file after another colon; it is ignored by the authorization
    module. This is what www.telescope.org uses for its combined
    password and group database.
    


    

    top
    

    AuthzDBMType Directive
    

    

    Description:Sets the type of database file that is used to
store list of user groups
    

    Syntax:AuthzDBMType default|SDBM|GDBM|NDBM|DB
    

    Default:AuthzDBMType default
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_authz_dbm
    

    
    
    Sets the type of database file that is used to store the list
    of user groups.
    The default database type is determined at compile time.  The
    availability of other types of database files also depends on
    compile-time settings.
    

    
    It is crucial that whatever program you use to create your group
    files is configured to use the same type of database.

    Compatibilité:Disponible depuis la version 2.3 d'Apache
    

    Sommaire
    

    
    Ce module fournit le coeur des fonctionnalités d'authentification
    permettant d'accorder ou de refuser l'accès à certaines zones du
    site web. Les directives fournies par le module
    mod_authn_core sont communes à tous les
    fournisseurs d'authentification.
    

    


    top
    

    

    Création d'alias de fournisseurs
d'authentification
    

    
    Il est possible de créer des fournisseurs d'authentification
    étendus dans le fichier de configuration et de leur assigner un
    alias. Le fournisseur ainsi nommé peut alors être référencé à l'aide
    des directives AuthBasicProvider ou AuthDigestProvider tout comme
    un fournisseur d'authentification de base. Outre la possibilité de
    créer et attribuer un alias à un fournisseur étendu, le même
    fournisseur d'authentification peut aussi être référencé par
    plusieurs sections relatives à une zone du site web.
    

    
    Exemples
    

	
    Cet exemple vérifie les mots de passe dans deux fichiers
	textes différents.

    Module:mod_authn_core
    

    
    
    Cette directive permet de définir l'identifiant d'autorisation
    pour un répertoire. Cet identifiant est fourni au client de façon à
    ce qu'il sache quels nom d'utilisateur et mot de passe envoyer.
    AuthName accepte un seul argument ; s'il
    contient des espaces, il doit être entouré de guillemets. Pour
    pouvoir fonctionner, la directive AuthName
    doit être utilisée en combinaison avec les directives AuthType et Require, ainsi que des
    directives comme AuthUserFile et AuthGroupFile.
    

   
    Par exemple :
    

   
    AuthName "Top Secret"
    


    
    La chaîne fournie comme argument à AuthName
    apparaîtra dans la boîte de dialogue d'authentification pour la
    plupart des navigateurs.

    Directive AuthType
    

    

    Description:Type d'authentification utilisateur
    

    Syntaxe:AuthType None|Basic|Digest|Form
    

    Contexte:répertoire, .htaccess
    

    Surcharges autorisées:AuthConfig
    

    Statut:Base
    

    Module:mod_authn_core
    

    
    
    Cette directive permet de définir le type d'authentification
    utilisateur pour un répertoire. Les types d'authentification
    disponibles sont None, Basic (implémenté
    par mod_auth_basic), Digest
    (implémenté par mod_auth_digest), et
    Form (implémenté par
    mod_auth_form).
    

    
    Pour mettre en oeuvre l'authentification, vous devez aussi
    utiliser les directives AuthName et Require. De plus, le serveur
    doit pouvoir disposer d'un module fournisseur d'authentification
    comme mod_authn_file et d'un module d'autorisation
    comme mod_authz_user.
    

    
    Le type d'authentification None désactive
    l'authentification. Lorsqu'une authentification est définie, elle
    est en général héritée par chacune des sections de configuration qui
    suivent, à moins qu'un autre type d'authentification ne soit
    spécifié. Si l'on ne souhaite pas mettre en oeuvre
    d'authentification pour une sous-section d'une section authentifiée,
    on doit utiliser le type d'authentification None ; dans
    l'exemple suivant, les clients peuvent accéder au répertoire
    /www/docs/public sans devoir s'authentifier :
    

    
    <Directory "/www/docs">
    AuthType Basic
    AuthName Documents
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    Require valid-user
</Directory>

<Directory "/www/docs/public">
    AuthType None
    Require all granted
</Directory>
    


    
    Veuillez noter que, lorsque l'authentification n'est pas
    activée, les clients qui se sont déjà authentifiés pour une autre
    zone de l'arborescence du site continueront en général à envoyer des
    en-tête d'authentification HTTP ou des cookies avec chaque requête,
    sans se préoccuper de savoir si le serveur nécessite vraiment une
    authentification pour chaque ressource.

    Description:Associates the requested filename's extensions
    with the file's behavior (handlers and filters)
    and content (mime-type, language, character set and
    encoding)
    

    Status:Base
    

    Module Identifier:mime_module
    

    Source File:mod_mime.c
    

    Summary
    

    
    This module is used to assign content metadata to the content
    selected for an HTTP response by mapping patterns in the
    URI or filenames to the metadata values.  For example, the filename
    extensions of content files often define the content's Internet
    media type, language, character set, and content-encoding. This
    information is sent in HTTP messages containing that content and
    used in content negotiation when selecting alternatives, such that
    the user's preferences are respected when choosing one of several
    possible contents to serve. See
    mod_negotiation for more information
    about content negotiation.
    

    
    The directives AddCharset, AddEncoding, AddLanguage and AddType are all used to map file
    extensions onto the metadata for that file. Respectively
    they set the character set, content-encoding, content-language,
    and media-type (content-type) of documents.  The directive TypesConfig is used to specify a
    file which also maps extensions onto media types. 
    

    
    In addition, mod_mime may define the handler and filters that originate and process
    content.  The directives AddHandler, AddOutputFilter, and AddInputFilter control the modules
    or scripts that serve the document.  The MultiviewsMatch directive allows
    mod_negotiation to consider these file extensions
    to be included when testing Multiviews matches.
    

    
    While mod_mime associates metadata
    with filename extensions, the core server
    provides directives that are used to associate all the files in a
    given container (e.g., <Location>, <Directory>, or <Files>) with particular
    metadata. These directives include ForceType, SetHandler, SetInputFilter, and SetOutputFilter.  The core directives
    override any filename extension mappings defined in
    mod_mime.
    

    
    Note that changing the metadata for a file does not
    change the value of the Last-Modified header.
    Thus, previously cached copies may still be used by a client or
    proxy, with the previous headers. If you change the
    metadata (language, content type, character set or
    encoding) you may need to 'touch' affected files (updating
    their last modified date) to ensure that all visitors are
    receive the corrected content headers.
    

    


    top
    

    

    Files with Multiple Extensions
    
    
    Files can have more than one extension; the order of the
    extensions is normally irrelevant. For example, if the
    file welcome.html.fr maps onto content type
    text/html and language French then the file
    welcome.fr.html will map onto exactly the same
    information.  If more than one extension is given that maps onto
    the same type of metadata, then the one to the right will
    be used, except for languages and content encodings. For example,
    if .gif maps to the media-type
    image/gif and .html maps to the
    media-type text/html, then the file
    welcome.gif.html will be associated with the
    media-type text/html.
    

    
    Languages and content encodings are treated accumulative, because one can assign
    more than one language or encoding to a particular resource. For example,
    the file welcome.html.en.de will be delivered with
    Content-Language: en, de and Content-Type:
    text/html.
    

    
    Care should be taken when a file with multiple extensions
    gets associated with both a media-type
    and a handler. This will
    usually result in the request being handled by the module associated
    with the handler. For example, if the .imap
    extension is mapped to the handler imap-file (from
    mod_imagemap) and the .html extension is
    mapped to the media-type text/html, then the file
    world.imap.html will be associated with both the
    imap-file handler and text/html media-type.
    When it is processed, the imap-file handler will be used,
    and so it will be treated as a mod_imagemap imagemap
    file.
    

    
    If you would prefer only the last dot-separated part of the
    filename to be mapped to a particular piece of meta-data, then do
    not use the Add* directives. For example, if you wish
    to have the file foo.html.cgi processed as a CGI
    script, but not the file bar.cgi.html, then instead
    of using AddHandler cgi-script .cgi, use
    

    
    Configure handler based on final extension only
    <FilesMatch "[^.]+\.cgi$">
  SetHandler cgi-script
</FilesMatch>
    

    


    top
    

    

    Content encoding
    
    
    A file of a particular media-type can additionally be encoded a
    particular way to simplify transmission over the Internet.
    While this usually will refer to compression, such as
    gzip, it can also refer to encryption, such a
    pgp or to an encoding such as UUencoding, which is
    designed for transmitting a binary file in an ASCII (text)
    format.
    

    
    The HTTP/1.1
    RFC, section 14.11 puts it this way:
    

    
    
      
    The Content-Encoding entity-header field is used as a modifier to
      the media-type. When present, its value indicates what additional
      content codings have been applied to the entity-body, and thus what
      decoding mechanisms must be applied in order to obtain the media-type
      referenced by the Content-Type header field. Content-Encoding is
      primarily used to allow a document to be compressed without losing
      the identity of its underlying media type.
    
    
    

    
    By using more than one file extension (see section above about multiple file
    extensions), you can indicate that a file is of a
    particular type, and also has a particular
    encoding. 
    

    
    For example, you may have a file which is a Microsoft Word
    document, which is pkzipped to reduce its size. If the
    .doc extension is associated with the Microsoft
    Word file type, and the .zip extension is
    associated with the pkzip file encoding, then the file
    Resume.doc.zip would be known to be a pkzip'ed Word
    document.
    

    
    Apache sends a Content-encoding header with the
    resource, in order to tell the client browser about the
    encoding method.
    

    
    Content-encoding: pkzip
    


    top
    

    

    Character sets and languages
    
    
    In addition to file type and the file encoding,
    another important piece of information is what language a
    particular document is in, and in what character set the file
    should be displayed. For example, the document might be written
    in the Vietnamese alphabet, or in Cyrillic, and should be
    displayed as such. This information, also, is transmitted in
    HTTP headers.
    

    
    The character set, language, encoding and mime type are all
    used in the process of content negotiation (See
    mod_negotiation) to determine
    which document to give to the client, when there are
    alternative documents in more than one character set, language,
    encoding or mime type. All filename extensions associations
    created with AddCharset,
    AddEncoding, AddLanguage and AddType directives
    (and extensions listed in the MimeMagicFile) participate in this select process.
    Filename extensions that are only associated using the AddHandler, AddInputFilter or AddOutputFilter directives may be included or excluded
    from matching by using the MultiviewsMatch directive.
    

    
    Charset
    
      
    To convey this further information, Apache optionally sends
      a Content-Language header, to specify the language
      that the document is in, and can append additional information
      onto the Content-Type header to indicate the
      particular character set that should be used to correctly
      render the information.
    

      
    
Content-Language: en, fr
Content-Type: text/plain; charset=ISO-8859-1
      
    

      
    The language specification is the two-letter abbreviation
      for the language. The charset is the name of the
      particular character set which should be used.

    AddCharset Directive
    

    

    Description:Maps the given filename extensions to the specified content
charset
    

    Syntax:AddCharset charset extension
[extension] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The AddCharset directive maps the given
    filename extensions to the specified content charset (the Internet
    registered name for a given character encoding). charset
    is the media
    type's charset parameter for resources with filenames containing
    extension. This mapping is added to any already in force,
    overriding any mappings that already exist for the same
    extension.
    

    
    Example
    AddLanguage ja .ja
AddCharset EUC-JP .euc
AddCharset ISO-2022-JP .jis
AddCharset SHIFT_JIS .sjis
    

    

    
    Then the document xxxx.ja.jis will be treated
    as being a Japanese document whose charset is ISO-2022-JP
    (as will the document xxxx.jis.ja). The
    AddCharset directive is useful for both to
    inform the client about the character encoding of the document so that
    the document can be interpreted and displayed appropriately, and for content negotiation,
    where the server returns one from several documents based on
    the client's charset preference.
    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.

    AddEncoding Directive
    

    

    Description:Maps the given filename extensions to the specified encoding
type
    

    Syntax:AddEncoding encoding extension
[extension] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The AddEncoding directive maps the given
    filename extensions to the specified HTTP content-encoding.
    encoding is the HTTP content coding to append to the
    value of the Content-Encoding header field for documents named with the
    extension. This mapping is added to any already in force,
    overriding any mappings that already exist for the same
    extension.
    

    
    Example
    AddEncoding x-gzip .gz
AddEncoding x-compress .Z
    

    

    
    This will cause filenames containing the .gz extension
    to be marked as encoded using the x-gzip encoding, and
    filenames containing the .Z extension to be marked as
    encoded with x-compress.
    

    
    Old clients expect x-gzip and x-compress,
    however the standard dictates that they're equivalent to
    gzip and compress respectively. Apache does
    content encoding comparisons by ignoring any leading x-.
    When responding with an encoding Apache will use whatever form
    (i.e., x-foo or foo) the
    client requested. If the client didn't specifically request a
    particular form Apache will use the form given by the
    AddEncoding directive. To make this long story
    short, you should always use x-gzip and
    x-compress for these two specific encodings. More
    recent encodings, such as deflate, should be
    specified without the x-.
    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.

    AddHandler Directive
    

    

    Description:Maps the filename extensions to the specified
handler
    

    Syntax:AddHandler handler-name extension
[extension] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    Files having the name extension will be served by the
    specified handler-name. This
    mapping is added to any already in force, overriding any mappings that
    already exist for the same extension. For example, to
    activate CGI scripts with the file extension .cgi, you
    might use:
    

    
    AddHandler cgi-script .cgi
    


    
    Once that has been put into your httpd.conf file, any file containing
    the .cgi extension will be treated as a CGI program.
    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    AddInputFilter maps the filename extension
    extension to the filters which
    will process client requests and POST input when they are received by
    the server. This is in addition to any filters defined elsewhere,
    including the SetInputFilter
    directive. This mapping is merged over any already in force, overriding
    any mappings that already exist for the same extension.
    

    
    If more than one filter is specified, they must be separated
    by semicolons in the order in which they should process the
    content. The filter is case-insensitive.
    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.

    AddLanguage Directive
    

    

    Description:Maps the given filename extension to the specified content
language
    

    Syntax:AddLanguage language-tag extension
[extension] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The AddLanguage directive maps the given
    filename extension to the specified content language.  Files with the
    filename extension are assigned an HTTP Content-Language
    value of language-tag corresponding to the language
    identifiers defined by RFC 3066.
    This directive overrides any mappings that already exist for the same
    extension.
    

    
    Example
    AddEncoding x-compress .Z
AddLanguage en .en
AddLanguage fr .fr
    

    

    
    Then the document xxxx.en.Z will be treated as
    being a compressed English document (as will the document
    xxxx.Z.en). Although the content language is
    reported to the client, the browser is unlikely to use this
    information. The AddLanguage directive is
    more useful for content
    negotiation, where the server returns one from several documents
    based on the client's language preference.
    

    
    If multiple language assignments are made for the same
    extension, the last one encountered is the one that is used.
    That is, for the case of:
    

    
    AddLanguage en .en
AddLanguage en-gb .en
AddLanguage en-us .en
    


    
    documents with the extension .en would be treated as
    being en-us.
    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.

    AddOutputFilter Directive

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The AddOutputFilter directive maps the
    filename extension extension to the filters which will process responses
    from the server before they are sent to the client. This is in
    addition to any filters defined elsewhere, including SetOutputFilter and AddOutputFilterByType directive. This mapping is merged
    over any already in force, overriding any mappings that already exist
    for the same extension.
    

    
    For example, the following configuration will process all
    .shtml files for server-side includes and will then
    compress the output using mod_deflate.
    

    
    AddOutputFilter INCLUDES;DEFLATE shtml
    


    
    If more than one filter is specified, they must be separated
    by semicolons in the order in which they should process the
    content. The filter argument is case-insensitive.
    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.
    

    
    Note that when defining a set of filters using the

    AddType Directive
    

    

    Description:Maps the given filename extensions onto the specified content
type
    

    Syntax:AddType media-type extension
[extension] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The AddType directive maps the given
    filename extensions onto the specified content
    type. media-type is the media
    type to use for filenames containing
    extension. This mapping is added to any already in
    force, overriding any mappings that already exist for the same
    extension.
    

    
    
      It is recommended that new media types be added using the
      AddType directive rather than changing the
      TypesConfig file.
    
    

    
    Example
    AddType image/gif .gif
    

    

    
    Or, to specify multiple file extensions in one directive:
    

    
    Example
    AddType image/jpeg jpeg jpg jpe
    

    

    
    The extension argument is case-insensitive and can
    be specified with or without a leading dot. Filenames may have multiple extensions and the
    extension argument will be compared against each of
    them.
    

    
    A similar effect to mod_negotiation's
    LanguagePriority
    can be achieved by qualifying a media-type with
    qs:
    

    
    Example
    AddType application/rss+xml;qs=0.8 .xml
    

    

    
    This is useful in situations, e.g. when a client
    requesting Accept: */* can not actually processes
    the content returned by the server.
    

    
    This directive primarily configures the content types generated for
    static files served out of the filesystem.  For resources other than
    static files, where the generator of the response typically specifies
    a Content-Type, this directive has no effect.
    


    
    Note
    
    
    If no handler is explicitly set for a request, the specified content
    type will also be used as the handler name. 
    

    
    When explicit directives such as
    SetHandler or
    AddHandler do not apply
    to the current request, the internal handler name normally set by those
    directives is instead set to the content type specified by this directive.
    
    
    
    
    This is a historical behavior that may be used by some third-party modules
    (such as mod_php) for taking responsibility for the matching request.
    
    

    
    Configurations that rely on such "synthetic" types should be avoided.
    Additionally, configurations that restrict access to
    SetHandler or
    AddHandler should
    restrict access to this directive as well.

    DefaultLanguage Directive
    

    

    Description:Defines a default language-tag to be sent in the Content-Language
header field for all resources in the current context that have not been
assigned a language-tag by some other means.
    

    Syntax:DefaultLanguage language-tag
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The DefaultLanguage directive tells Apache
    that all resources in the directive's scope (e.g., all resources
    covered by the current <Directory> container) that don't have an explicit language
    extension (such as .fr or .de as configured
    by AddLanguage) should be
    assigned a Content-Language of language-tag. This allows
    entire directory trees to be marked as containing Dutch content, for
    instance, without having to rename each file. Note that unlike using
    extensions to specify languages, DefaultLanguage
    can only specify a single language.
    

    
    If no DefaultLanguage directive is in force
    and a file does not have any language extensions as configured
    by AddLanguage, then no
    Content-Language header field will be generated.
    

    
    Example
    DefaultLanguage en

    ModMimeUsePathInfo Directive
    

    

    Description:Tells mod_mime to treat path_info
components as part of the filename
    

    Syntax:ModMimeUsePathInfo On|Off
    

    Default:ModMimeUsePathInfo Off
    

    Context:directory
    

    Status:Base
    

    Module:mod_mime
    

    
    
    The ModMimeUsePathInfo directive is used to
    combine the filename with the path_info URL component to
    apply mod_mime's directives to the request. The default
    value is Off - therefore, the path_info
    component is ignored.
    

    
    This directive is recommended when you have a virtual filesystem.
    

    
    Example
    ModMimeUsePathInfo On
    

    

    
    If you have a request for /index.php/foo.shtml
    mod_mime will now treat the
    incoming request as /index.php/foo.shtml and directives
    like AddOutputFilter INCLUDES .shtml will add the
    INCLUDES filter to the request. If ModMimeUsePathInfo is not set, the
    INCLUDES filter will not be added. This will work
    analogously for virtual paths, such as those defined by
    <Location>

    MultiviewsMatch Directive
    

    

    Description:The types of files that will be included when searching for
a matching file with MultiViews
    

    Syntax:MultiviewsMatch Any|NegotiatedOnly|Filters|Handlers
[Handlers|Filters]
    

    Default:MultiviewsMatch NegotiatedOnly
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_mime
    

    
    
    MultiviewsMatch permits three different
    behaviors for mod_negotiation's
    Multiviews feature.  Multiviews allows a request for a file,
    e.g. index.html, to match any negotiated
    extensions following the base request, e.g.
    index.html.en, index.html.fr, or
    index.html.gz.
    

    
    The NegotiatedOnly option provides that every extension
    following the base name must correlate to a recognized
    mod_mime extension for content negotiation, e.g.
    Charset, Content-Type, Language, or Encoding.  This is the strictest
    implementation with the fewest unexpected side effects, and is the
    default behavior.
    

    
    To include extensions associated with Handlers and/or Filters,
    set the MultiviewsMatch directive to either
    Handlers, Filters, or both option keywords.
    If all other factors are equal, the smallest file will be served,
    e.g. in deciding between index.html.cgi of 500
    bytes and index.html.pl of 1000 bytes, the .cgi
    file would win in this example. Users of .asis files
    might prefer to use the Handler option, if .asis files are
    associated with the asis-handler.
    

    
    You may finally allow Any extensions to match, even if
    mod_mime doesn't recognize the extension. This can cause
    unpredictable results, such as serving .old or .bak files the webmaster
    never expected to be served.
    

    
    For example, the following configuration will allow handlers
    and filters to participate in Multviews, but will exclude unknown
    files:
    

    
    MultiviewsMatch Handlers Filters
    


    
    MultiviewsMatch is not allowed in a
    <Location> or <LocationMatch> section.

    allows .htaccess files in subdirectories to undo
    any associations inherited from parent directories or the

    /foo/.htaccess:
    AddEncoding x-gzip .gz
AddType text/plain .asc
<Files "*.gz.asc">
    RemoveEncoding .gz
</Files>
    

    

    
    This will cause foo.gz to be marked as being
    encoded with the gzip method, but foo.gz.asc as an
    unencoded plaintext file.
    

    
    Note
    
      
    RemoveEncoding directives are processed
      after any AddEncoding
      directives, so it is possible they may undo the effects of the latter

    /foo/bar/.htaccess:
    RemoveHandler .html
    

    

    
    This has the effect of returning .html files in
    the /foo/bar directory to being treated as normal
    files, rather than as candidates for parsing (see the mod_include module).

    The TypesConfig directive sets the
    location of the media types
    configuration file. File-path is relative to the
    ServerRoot. This file sets
    the default list of mappings from filename extensions to content
    types. Most administrators use the mime.types file
    provided by their OS, which associates common filename
    extensions with the official list of IANA registered media types
    maintained at http://www.iana.org/assignments/media-types/index.html
    as well as a large number of unofficial types.  This
    simplifies the httpd.conf file by providing the
    majority of media-type definitions, and may be overridden by
    AddType directives as
    needed. You should not edit the mime.types file,
    because it may be replaced when you upgrade your server.
    

    
    The file contains lines in the format of the arguments to
    an AddType directive:
    

    
    
      media-type [extension] ...
    
    

    
    The case of the extension does not matter. Blank lines, and lines
    beginning with a hash character (#) are ignored.
    Empty lines are there for completeness (of the mime.types file).
    Apache httpd can still determine these types with mod_mime_magic.
    
    

    
    
      Please do not send requests to the Apache HTTP
      Server Project to add any new entries in the distributed
      mime.types file unless (1) they are already
      registered with IANA, and (2) they use widely accepted,
      non-conflicting filename extensions across platforms.
      category/x-subtype requests will be automatically
      rejected, as will any new two-letter extensions as they will
      likely conflict later with the already crowded language and
      character set namespace.

    Sommaire
    

    
    Ce module fournit le gestionnaire send-as-is qui
    permet au serveur HTTP Apache d'envoyer le document sans ajouter la plupart des
    en-têtes HTTP habituels.
    

    
    On peut l'utiliser pour envoyer tous types de données en
    provenance du serveur, y compris les redirections et autres réponses
    HTTP spéciales, sans devoir faire appel à un script CGI ou nph.
    

    
    Pour des raisons historiques, ce module traitera aussi tout
    fichier dont le type MIME est httpd/send-as-is.
    

    


    top
    

    

    Mode d'emploi
    

    
    Dans le fichier de configuration, associez les fichiers asis au
    gestionnaire send-as-is comme ceci :
    

    
    AddHandler send-as-is asis
    


    
    Le contenu de tout fichier possédant l'extension
    .asis sera envoyé par Apache httpd au client pratiquement tel
    quel. En particulier, les en-têtes HTTP seront déduits du fichier
    lui-même selon les règles du module mod_cgi, si
    bien qu'un fichier asis doit inclure des en-têtes valides, et
    utiliser l'en-tête CGI Status: pour déterminer le code de réponse
    HTTP. L'en-tête Content-Length: sera automatiquement
    inséré ou, s'il est déjà présent, corrigé par httpd.
    

    
    Voici un exemple de fichier dont le contenu est envoyé tel
    quel pour informer un client qu'un fichier a été déplacé.
    


    
    
      Status: 301 Ou se trouve cette URL maintenant
    
      Location: http://xyz.example.com/foo/bar.html
    
      Content-type: text/html
    
      
    
      <html>
    
      <head>
    
      <title>Mauvaises excuses</title>
    
      </head>
    
      <body>
    
      <h1>La merveilleuse page de Fred a été déplacée vers
    
      <a href="http://xyz.example.com/foo/bar.html">le site de
      Joe</a>.
    
      </h1>
    
      </body>
    
      </html>
    
    

    
    Notes :
    
    
    Le serveur ajoute systématiquement les en-têtes
    Date: et Server: aux données qu'il envoie
    au client, si bien qu'ils n'ont pas besoin d'être inclus dans le
    fichier. Le serveur n'ajoute pas d'en-tête
    Last-Modified, ce qu'il devrait probablement faire.

    Description:Provides Lua hooks into various portions of the httpd
request processing
    

    Status:Extension

    Source File:mod_lua.c
    

    Compatibility:2.3 and later
    

    Summary
    


    This module allows the server to be extended with scripts written in the
Lua programming language.  The extension points (hooks) available with
mod_lua include many of the hooks available to
natively compiled Apache HTTP Server modules, such as mapping requests to
files, generating dynamic responses, access control, authentication, and
authorization
    


    More information on the Lua programming language can be found at the
the Lua website.
    


    Warning
    

    This module holds a great deal of power over httpd, which is both a 
strength and a potential security risk. It is not recommended 
that you use this module on a server that is shared with users you do not 
trust, as it can be abused to change the internal workings of httpd.

    Basic Configuration
    


    The basic module loading directive is
    


    LoadModule lua_module modules/mod_lua.so
    



    
mod_lua provides a handler named lua-script,
which can be used with a SetHandler or
AddHandler directive:
    


    <Files "*.lua">
    SetHandler lua-script
</Files>
    



    
This will cause mod_lua to handle requests for files
ending in .lua by invoking that file's
handle function.

    


    For more flexibility, see LuaMapHandler.

    


    top
    

    

    Writing Handlers
    

     In the Apache HTTP Server API, the handler is a specific kind of hook
responsible for generating the response.  Examples of modules that include a
handler are mod_proxy, mod_cgi,
and mod_status.
    


    mod_lua always looks to invoke a Lua function for the handler, rather than
just evaluating a script body CGI style. A handler function looks
something like this:
    



    example.lua
    
-- example handler

require "string"

--[[
     This is the default method name for Lua handlers, see the optional
     function-name in the LuaMapHandler directive to choose a different
     entry point.
--]]
function handle(r)
    r.content_type = "text/plain"

    if r.method == 'GET' then
        r:puts("Hello Lua World!\n")
        for k, v in pairs( r:parseargs() ) do
            r:puts( string.format("%s: %s\n", k, v) )
        end
    elseif r.method == 'POST' then
        r:puts("Hello Lua World!\n")
        for k, v in pairs( r:parsebody() ) do
            r:puts( string.format("%s: %s\n", k, v) )
        end
    elseif r.method == 'PUT' then
-- use our own Error contents
        r:puts("Unsupported HTTP method " .. r.method)
        r.status = 405
        return apache2.OK
    else
-- use the ErrorDocument
        return 501
    end
    return apache2.OK
end
    



    
This handler function just prints out the uri or form encoded
arguments to a plaintext page.

    


    
This means (and in fact encourages) that you can have multiple
handlers (or hooks, or filters) in the same script.

    Writing Authorization Providers
    



    mod_authz_core provides a high-level interface to
authorization that is much easier to use than using into the relevant
hooks directly. The first argument to the
Require directive gives
the name of the responsible authorization provider. For any
Require line,
mod_authz_core will call the authorization provider
of the given name, passing the rest of the line as parameters. The
provider will then check authorization and pass the result as return
value.
    


    The authz provider is normally called before authentication. If it needs to
know the authenticated user name (or if the user will be authenticated at
all), the provider must return apache2.AUTHZ_DENIED_NO_USER.
This will cause authentication to proceed and the authz provider to be
called a second time.
    


    The following authz provider function takes two arguments, one ip
address and one user name. It will allow access from the given ip address
without authentication, or if the authenticated user matches the second
argument:
    


    authz_provider.lua
    

require 'apache2'

function authz_check_foo(r, ip, user)
    if r.useragent_ip == ip then
        return apache2.AUTHZ_GRANTED
    elseif r.user == nil then
        return apache2.AUTHZ_DENIED_NO_USER
    elseif r.user == user then
        return apache2.AUTHZ_GRANTED
    else
        return apache2.AUTHZ_DENIED
    end
end
    



    The following configuration registers this function as provider
foo and configures it for URL /:
    

    LuaAuthzProvider foo authz_provider.lua authz_check_foo
<Location "/">
  Require foo 10.1.2.3 john_doe
</Location>

    Writing Hooks
    


    Hook functions are how modules (and Lua scripts) participate in the
processing of requests. Each type of hook exposed by the server exists for
a specific purpose, such as mapping requests to the file system,
performing access control, or setting mime types:
    


    
        Hook phase
        mod_lua directive
        Description
    
    

    
        Quick handler
        LuaQuickHandler
        This is the first hook that will be called after a request has 
            been mapped to a host or virtual host
    
    

    
        Pre-Translate name
        LuaHookPreTranslateName
        This phase translates the requested URI into a filename on the
            system, before decoding occurs. Modules such as mod_proxy
            can operate in this phase.
    
    

    
        Translate name
        LuaHookTranslateName
        This phase translates the requested URI into a filename on the 
            system. Modules such as mod_alias and
            mod_rewrite operate in this phase.
    
    

    
        Map to storage
        LuaHookMapToStorage
        This phase maps files to their physical, cached or external/proxied storage. 
            It can be used by proxy or caching modules
    
    

    
        Check Access
        LuaHookAccessChecker
        This phase checks whether a client has access to a resource. This 
            phase is run before the user is authenticated, so beware.
        
    
    

    
        Check User ID
        LuaHookCheckUserID
        This phase it used to check the negotiated user ID
    
    

    
        Check Authorization
        LuaHookAuthChecker or 
            LuaAuthzProvider
        This phase authorizes a user based on the negotiated credentials, such as 
            user ID, client certificate etc.
        
    
    

    
        Check Type
        LuaHookTypeChecker
        This phase checks the requested file and assigns a content type and 
            a handler to it
    
    

    
        Fixups
        LuaHookFixups
        This is the final "fix anything" phase before the content handlers 
            are run. Any last-minute changes to the request should be made here.
    
    

    
        Content handler
        fx. .lua files or through LuaMapHandler
        This is where the content is handled. Files are read, parsed, some are run, 
            and the result is sent to the client
    
    

    
        Logging
        LuaHookLog
        Once a request has been handled, it enters several logging phases, 
            which logs the request in either the error or access log. Mod_lua
            is able to hook into the start of this and control logging output.
    
    

    


    Hook functions are passed the request object as their only argument 
(except for LuaAuthzProvider, which also gets passed the arguments from 
the Require directive).
They can return any value, depending on the hook, but most commonly
they'll return OK, DONE, or DECLINED, which you can write in Lua as
apache2.OK, apache2.DONE, or
apache2.DECLINED, or else an HTTP status code.
    



    translate_name.lua
    
-- example hook that rewrites the URI to a filesystem path.

require 'apache2'

function translate_name(r)
    if r.uri == "/translate-name" then
        r.filename = r.document_root .. "/find_me.txt"
        return apache2.OK
    end
    -- we don't care about this URL, give another module a chance
    return apache2.DECLINED
end
    




    translate_name2.lua
    
--[[ example hook that rewrites one URI to another URI. It returns a
     apache2.DECLINED to give other URL mappers a chance to work on the
     substitution, including the core translate_name hook which maps based
     on the DocumentRoot.

     Note: Use the early/late flags in the directive to make it run before
           or after mod_alias.
--]]

require 'apache2'

function translate_name(r)
    if r.uri == "/translate-name" then
        r.uri = "/find_me.txt"
        return apache2.DECLINED
    end
    return apache2.DECLINED
end

    Data Structures
    


    

    request_rec
    
        
    
        
    The request_rec is mapped in as a userdata. It has a metatable
        which lets you do useful things with it. For the most part it
        has the same fields as the request_rec struct, many of which are writable as
        well as readable.  (The table fields' content can be changed, but the
        fields themselves cannot be set to different tables.)

          content_type
          string
          yes

          string
          yes
          The file name that the request maps to, f.x. /www/example.com/foo.txt. This can be 
            changed in the pre-translate-name, translate-name or map-to-storage phases of a request to allow the

            lua-script if it is to be served by mod_lua. This is typically set by the 
            AddHandler or SetHandler 
            directives, but could also be set via mod_lua to allow another handler to serve up a specific request 
            that would otherwise not be served by it.

          string
          no
          The host name, as set by the Host: header or by a full URI.

    Built in functions
    


    The request_rec object has (at least) the following methods:
    


    r:flush()   -- flushes the output buffer.
            -- Returns true if the flush was successful, false otherwise.

while we_have_stuff_to_send do
    r:puts("Bla bla bla\n") -- print something to client
    r:flush() -- flush the buffer (send to client)

    Modifying contents with Lua filters
    
    
    
    
    Filter functions implemented via LuaInputFilter 
    or LuaOutputFilter are designed as 
    three-stage non-blocking functions using coroutines to suspend and resume a 
    function as buckets are sent down the filter chain. The core structure of 
    such a function is:
    
    
    
    function filter(r)
    -- Our first yield is to signal that we are ready to receive buckets.
    -- Before this yield, we can set up our environment, check for conditions,
    -- and, if we deem it necessary, decline filtering a request altogether:
    if something_bad then
        return -- This would skip this filter.
    end
    -- Regardless of whether we have data to prepend, a yield MUST be called here.
    -- Note that only output filters can prepend data. Input filters must use the 
    -- final stage to append data to the content.
    coroutine.yield([optional header to be prepended to the content])
    
    -- After we have yielded, buckets will be sent to us, one by one, and we can 
    -- do whatever we want with them and then pass on the result.
    -- Buckets are stored in the global variable 'bucket', so we create a loop
    -- that checks if 'bucket' is not nil:
    while bucket ~= nil do
        local output = mangle(bucket) -- Do some stuff to the content
        coroutine.yield(output) -- Return our new content to the filter chain
    end

    -- Once the buckets are gone, 'bucket' is set to nil, which will exit the 
    -- loop and land us here. Anything extra we want to append to the content
    -- can be done by doing a final yield here. Both input and output filters 
    -- can append data to the content in this phase.
    coroutine.yield([optional footer to be appended to the content])
end

    Database connectivity
    
    
    
    
    Mod_lua implements a simple database feature for querying and running commands
    on the most popular database engines (mySQL, PostgreSQL, FreeTDS, ODBC, SQLite, Oracle)
    as well as mod_dbd.
    
    
    
    The example below shows how to acquire a database handle and return information from a table:
    
    
    function handle(r)
    -- Acquire a database handle
    local database, err = r:dbacquire("mysql", "server=localhost,user=someuser,pass=somepass,dbname=mydb")
    if not err then
        -- Select some information from it
        local results, err = database:select(r, "SELECT `name`, `age` FROM `people` WHERE 1")
        if not err then
            local rows = results(0) -- fetch all rows synchronously
            for k, row in pairs(rows) do
                r:puts( string.format("Name: %s, Age: %s<br/>", row[1], row[2]) )
            end
        else
            r:puts("Database query error: " .. err)
        end
        database:close()
    else
        r:puts("Could not connect to the database: " .. err)
    end
end
    

    
    
    To utilize mod_dbd, specify mod_dbd
    as the database type, or leave the field blank:
    
    
    
    local database = r:dbacquire("mod_dbd")
    

    
    Database object and contained functions
    
        
        
    The database object returned by dbacquire has the following methods:
    
        
    Normal select and query from a database:
    
    
    -- Run a statement and return the number of rows affected:
local affected, errmsg = database:query(r, "DELETE FROM `tbl` WHERE 1")

-- Run a statement and return a result set that can be used synchronously or async:
local result, errmsg = database:select(r, "SELECT * FROM `people` WHERE 1")
    

        
    Using prepared statements (recommended):
    
    
    -- Create and run a prepared statement:
local statement, errmsg = database:prepare(r, "DELETE FROM `tbl` WHERE `age` > %u")
if not errmsg then
    local result, errmsg = statement:query(20) -- run the statement with age > 20
end

-- Fetch a prepared statement from a DBDPrepareSQL directive:
local statement, errmsg = database:prepared(r, "someTag")
if not errmsg then
    local result, errmsg = statement:select("John Doe", 123) -- inject the values "John Doe" and 123 into the statement
end
    

        
    Escaping values, closing databases etc:
    
    
    -- Escape a value for use in a statement:
local escaped = database:escape(r, [["'|blabla]])

-- Close a database connection and free up handles:
database:close()

-- Check whether a database connection is up and running:
local connected = database:active()
    

    
    
    Working with result sets
    
    
    
    The result set returned by db:select or by the prepared statement functions 
    created through db:prepare can be used to
    fetch rows synchronously or asynchronously, depending on the row number specified:
    
    result(0) fetches all rows in a synchronous manner, returning a table of rows.
    
    result(-1) fetches the next available row in the set, asynchronously.
    
    result(N) fetches row number N, asynchronously:
    
    
    
    -- fetch a result set using a regular query:
local result, err = db:select(r, "SELECT * FROM `tbl` WHERE 1")

local rows = result(0) -- Fetch ALL rows synchronously
local row = result(-1) -- Fetch the next available row, asynchronously
local row = result(1234) -- Fetch row number 1234, asynchronously
local row = result(-1, true) -- Fetch the next available row, using row names as key indexes.
    

    
    One can construct a function that returns an iterative function to iterate over all rows 
    in a synchronous or asynchronous way, depending on the async argument:
    
    
    
    function rows(resultset, async)
    local a = 0
    local function getnext()
        a = a + 1
        local row = resultset(-1)
        return row and a or nil, row
    end
    if not async then
        return pairs(resultset(0))
    else
        return getnext, self
    end
end

local statement, err = db:prepare(r, "SELECT * FROM `tbl` WHERE `age` > %u")
if not err then
     -- fetch rows asynchronously:
    local result, err = statement:select(20)
    if not err then
        for index, row in rows(result, true) do
            ....
        end
    end

     -- fetch rows synchronously:
    local result, err = statement:select(20)
    if not err then
        for index, row in rows(result, false) do
            ....
        end
    end
end
    

    
    
    Closing a database connection
    
        

    
    Database handles should be closed using database:close() when they are no longer
    needed. If you do not close them manually, they will eventually be garbage collected and 
    closed by mod_lua, but you may end up having too many unused connections to the database 
    if you leave the closing up to mod_lua. Essentially, the following two measures are
    the same:
    
    
    
    -- Method 1: Manually close a handle
local database = r:dbacquire("mod_dbd")
database:close() -- All done

-- Method 2: Letting the garbage collector close it
local database = r:dbacquire("mod_dbd")
database = nil -- throw away the reference
collectgarbage() -- close the handle via GC
    

    
    
    Precautions when working with databases
    
    
    
    Although the standard query and run functions are freely 
    available, it is recommended that you use prepared statements whenever possible, to 
    both optimize performance (if your db handle lives on for a long time) and to minimize 
    the risk of SQL injection attacks. run and query should only
    be used when there are no variables inserted into a statement (a static statement). 
    When using dynamic statements, use db:prepare or db:prepared.

    Specify the behavior of the in-memory code cache. The default
    is stat, which stats the top level script (not any included
    ones) each time that file is needed, and reloads it if the
    modified time indicates it is newer than the one it has
    already loaded. The other values cause it to keep the file
    cached forever (don't stat and replace) or to never cache the
    file.
    

    
    In general stat or forever is good for production, and stat or never
    for development.
    

    
    Examples:
    LuaCodeCache stat
LuaCodeCache forever
LuaCodeCache never

-- If request has no auth info, set the response header and
-- return a 401 to ask the browser for basic auth info.
-- If request has auth info, don't actually look at it, just
-- pretend we got userid 'foo' and validated it.
-- Then check if the userid is 'foo' and accept the request.
function authcheck_hook(r)

   -- look for auth info
   auth = r.headers_in['Authorization']
   if auth ~= nil then
     -- fake the user
     r.user = 'foo'
   end

   if r.user == nil then
      r:debug("authcheck: user is nil, returning 401")
      r.err_headers_out['WWW-Authenticate'] = 'Basic realm="WallyWorld"'
      return 401
   elseif r.user == "foo" then

    This simple logging hook allows you to run a function when httpd enters the 
    logging phase of a request. With it, you can append data to your own logs, 
    manipulate data before the regular log is written, or prevent a log entry 
    from being created. To prevent the usual logging from happening, simply return
    apache2.DONE in your logging handler, otherwise return 
    apache2.OK to tell httpd to log as normal.

    

    Example:
    

    LuaHookLog "/path/to/script.lua" logger
    


    -- /path/to/script.lua --
function logger(r)
    -- flip a coin:
    -- If 1, then we write to our own Lua log and tell httpd not to log
    -- in the main log.
    -- If 2, then we just sanitize the output a bit and tell httpd to 
    -- log the sanitized bits.

    if math.random(1,2) == 1 then
        -- Log stuff ourselves and don't log in the regular log
        local f = io.open("/foo/secret.log", "a")
        if f then
            f:write("Something secret happened at " .. r.uri .. "\n")
            f:close()
        end
        return apache2.DONE -- Tell httpd not to use the regular logging functions
    else
        r.uri = r.uri:gsub("somesecretstuff", "") -- sanitize the URI
        return apache2.OK -- tell httpd to log it.

    Add a hook (at APR_HOOK_MIDDLE) to the translate name phase of
    request processing. The hook function receives a single
    argument, the request_rec, and should return a status code,
    which is either an HTTP error code, or the constants defined
    in the apache2 module: apache2.OK, apache2.DECLINED, or
    apache2.DONE. 
    

    
    For those new to hooks, basically each hook will be invoked
    until one of them returns apache2.OK. If your hook doesn't
    want to do the translation it should just return
    apache2.DECLINED. If the request should stop processing, then
    return apache2.DONE.
    

    
    Example:
    


    # httpd.conf
LuaHookTranslateName "/scripts/conf/hooks.lua" silly_mapper
    



    -- /scripts/conf/hooks.lua --
require "apache2"
function silly_mapper(r)

    Provides a means of adding a Lua function as an input filter. 
As with output filters, input filters work as coroutines, 
first yielding before buffers are sent, then yielding whenever 
a bucket needs to be passed down the chain, and finally (optionally) 
yielding anything that needs to be appended to the input data. The 
global variable bucket holds the buckets as they are passed 
onto the Lua script:

    


    LuaInputFilter myInputFilter "/www/filter.lua" input_filter
<Files "*.lua">
  SetInputFilter myInputFilter
</Files>
    


    --[[
    Example input filter that converts all POST data to uppercase.
]]--
function input_filter(r)
    print("luaInputFilter called") -- debug print
    coroutine.yield() -- Yield and wait for buckets
    while bucket do -- For each bucket, do...
        local output = string.upper(bucket) -- Convert all POST data to uppercase
        coroutine.yield(output) -- Send converted data down the chain
    end
    -- No more buckets available.
    coroutine.yield("&filterSignature=1234") -- Append signature at the end
end
    


    
The input filter supports denying/skipping a filter if it is deemed unwanted:

    

    function input_filter(r)
    if not good then
        return -- Simply deny filtering, passing on the original content instead
    end
    coroutine.yield() -- wait for buckets
    ... -- insert filter stuff here

    This directive matches a uri pattern to invoke a specific
    handler function in a specific file. It uses PCRE regular
    expressions to match the uri, and supports interpolating
    match groups into both the file path and the function name. 
    Be careful writing your regular expressions to avoid security
    issues.
    
   
    Examples:
    LuaMapHandler "/(\w+)/(\w+)" "/scripts/$1.lua" "handle_$2"
    

    
        
    This would match uri's such as /photos/show?id=9
        to the file /scripts/photos.lua and invoke the
        handler function handle_show on the lua vm after
        loading that file.
    


    LuaMapHandler "/bingo" "/scripts/wombat.lua"
    

        
    This would invoke the "handle" function, which
        is the default if no specific function name is
        provided.

            will have the same server_rec. To accommodate this,
            server scoped Lua states are stored in an apr
            resource list. The min and max arguments 
            specify the minimum and maximum number of Lua states to keep in the 
            pool.
    
   
    
    
    
    Generally speaking, the thread and server scopes 
    execute roughly 2-3 times faster than the rest, because they don't have to 
    spawn new Lua states on every request (especially with the event MPM, as 
    even keepalive requests will use a new thread for each request). If you are 
    satisfied that your scripts will not have problems reusing a state, then 
    the thread or server scopes should be used for 
    maximum performance. While the thread scope will provide the 
    fastest responses, the server scope will use less memory, as 
    states are pooled, allowing f.x. 1000 threads to share only 100 Lua states, 
    thus using only 10% of the memory required by the thread scope.

    Sommaire
    

    
    Ce module multi-processus (MPM) implémente un serveur web avec
    démarrage anticipé de processus. Chaque processus du serveur peut
    répondre aux requêtes entrantes, et un processus parent contrôle la
    taille du jeu de processus enfants. Il est particulièrement indiqué pour les
    sites qui ne doivent pas utiliser les threads afin de maintenir une
    compatibilité avec certaines bibliothèques non sûres du point de vue
    des threads. C'est également le MPM le plus approprié si l'on veut
    isoler les requêtes les unes des autres, de façon à ce qu'un
    problème concernant une requête n'affecte pas les autres.
    

    
    Ce MPM s'auto-contrôle de manière efficace, de sorte qu'il est
    rarement nécessaire d'ajuster ses directives de configuration. Le
    plus important est la définition de la directive MaxRequestWorkers ; sa valeur doit être
    assez grande pour pouvoir traiter autant de requêtes simultanées que
    vous pensez recevoir, mais assez petite pour conserver suffisamment
    de mémoire RAM pour tous les processus.
    

    


    top
    

    

    Comment ça marche
    
    
    Un processus de contrôle unique a pour tâche de lancer les
    processus enfants qui attendent les connexions et les traitent au
    fur et à mesure qu'elles arrivent. Apache httpd essaie toujours de
    maintenir plusieurs processus serveurs inactifs ou en
    réserve, afin de pouvoir traiter les requêtes entrantes. De
    cette façon, les clients n'ont pas besoin d'attendre le démarrage
    d'un nouveau processus enfant pour que leurs requêtes puissent être
    traitées.
    

    
    Les directives StartServers, MinSpareServers, MaxSpareServers et MaxRequestWorkers permettent de contrôler
    la manière dont le processus parent crée les processus enfants pour
    traiter les requêtes. En général, Apache httpd s'auto-contrôle de manière
    efficace, de sorte que la plupart des sites peuvent conserver les
    valeurs par défaut des directives. Les sites qui doivent traiter
    plus de 256 requêtes simultanées doivent augmenter la valeur de
    MaxRequestWorkers, alors que les
    sites dont la ressource mémoire est limitée doivent la diminuer afin
    d'éviter une hyperactivité du serveur (utilisation excessive de la
    mémoire virtuelle sur disque). Vous trouverez plus d'informations à
    propos du contrôle de la création de processus dans le document conseils en matière de
    performances
    

    
    Alors que le processus parent est en général démarré en tant que
    root sous Unix afin de pouvoir se mettre à l'écoute sur le port 80, les
    processus enfants sont lancés par Apache httpd sous un utilisateur avec
    privilèges restreints. On peut contrôler les privilèges accordés aux
    processus enfants d'Apache httpd à l'aide des directives User et Group. Les processus enfants doivent
    être en mesure de lire tous les contenus destinés à être servis,
    mais leurs privilèges doivent être aussi bas que possible.
    

    
    La directive MaxConnectionsPerChild permet de
    contrôler la fréquence à laquelle le serveur recycle ses processus
    en arrêtant les plus anciens et en en lançant de nouveaux.
    

    
    Ce module MPM utilise le mutex mpm-accept pour
    sérialiser l'accès aux connexions entrantes lorsque peut se
    présenter un problème d'afflux de requêtes (en général quand il y a
    plusieurs sockets en écoute). Les aspects de l'implémentation de ce
    mutex peuvent être configurés via la directive Mutex. Vous trouverez des informations
    supplémentaires à propos de ce mutex dans la documentation à propos
    des  conseils en matière de
    performances

    Directive MaxSpareServers
    

    

    Description:Nombre maximum de processus serveurs enfants
inactifs
    

    Syntaxe:MaxSpareServers nombre
    

    Défaut:MaxSpareServers 10
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:prefork
    

    
    
    La directive MaxSpareServers permet de
    définir le nombre maximum souhaité de processus serveurs enfants
    inactifs. Un processus inactif est un processus qui ne
    traite pas de requête. S'il y a plus de
    MaxSpareServers processus inactifs, le
    processus parent arrêtera les processus excédentaires.
    

    
    La modification de ce paramètre n'est nécessaire que
    dans le cas de sites très sollicités. Définir ce paramètre à une
    valeur très grande est cependant dans la plupart des cas une
    mauvaise idée. Si vous essayez d'affecter à ce paramètre une valeur
    égale ou inférieure à la valeur de MinSpareServers, le serveur HTTP Apache
    l'ajustera automatiquement à la valeur de 
    MinSpareServers + 1.

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:prefork
    

    
    
    La directive MinSpareServers permet de
    définir le nombre minimum désiré de processus serveurs enfants
    inactifs. Un processus inactif est un processus qui ne
    traite pas de requête. S'il y a moins de
    MinSpareServers processus inactifs, le
    processus parent va créer de nouveaux enfants de la manière suivante
    : il en crée un, attend une seconde, il en crée deux, attend une
    seconde, il en crée quatre, puis continue ainsi exponentiellement
    jusu'à ce que son taux de création de processus enfants soit de 32
    par seconde. Il ne s'arrête que lorsque le nombre de processus
    enfants correspond à la définition de la directive
    MinSpareServers.
    

    
    La modification de ce paramètre n'est nécessaire que
    dans le cas de sites très sollicités. Définir ce paramètre à une
    valeur très grande est dans la plupart des cas une mauvaise
    idée.

    Summary
    

    
    This module implements the Internet Server extension API. It
    allows Internet Server extensions (e.g. ISAPI .dll
    modules) to be served by Apache for Windows, subject to the
    noted restrictions.
    

    
    ISAPI extension modules (.dll files) are written by third
    parties. The Apache Group does not author these modules, so we
    provide no support for them. Please contact the ISAPI's author
    directly if you are experiencing problems running their ISAPI
    extension. Please do not post such problems to
    Apache's lists or bug reporting pages.

    Usage
    

    
    In the server configuration file, use
    the AddHandler directive to
    associate ISAPI files with the isapi-handler handler, and map
    it to them with their file extensions. To enable any .dll file to be
    processed as an ISAPI extension, edit the httpd.conf file and add the
    following line:
    
    
    AddHandler isapi-handler .dll
    


    
    In older versions of the Apache server,
    isapi-isa was the proper handler name, rather than
    isapi-handler. As of 2.3 development versions of the Apache
    server, isapi-isa is no longer valid. You will need to
    change your configuration to use isapi-handler
    instead.
    

    
    There is no capability within the Apache server to leave a
    requested module loaded. However, you may preload and keep a
    specific module loaded by using the following syntax in your
    httpd.conf:
    
    
    ISAPICacheFile c:/WebWork/Scripts/ISAPI/mytest.dll
    


    
    Whether or not you have preloaded an ISAPI extension, all
    ISAPI extensions are governed by the same permissions and
    restrictions as CGI scripts. That is, Options ExecCGI must be set for the
    directory that contains the ISAPI .dll file.
    

    
    Review the Additional Notes and the Programmer's Journal for additional details
    and clarification of the specific ISAPI support offered by
    mod_isapi.

    Additional Notes
    

    
    Apache's ISAPI implementation conforms to all of the ISAPI
    2.0 specification, except for some "Microsoft-specific"
    extensions dealing with asynchronous I/O. Apache's I/O model
    does not allow asynchronous reading and writing in a manner
    that the ISAPI could access. If an ISA tries to access
    unsupported features, including async I/O, a message is placed
    in the error log to help with debugging. Since these messages
    can become a flood, the directive ISAPILogNotSupported
    Off exists to quiet this noise.
    

    
    Some servers, like Microsoft IIS, load the ISAPI extension
    into the server and keep it loaded until memory usage is too
    high, or unless configuration options are specified. Apache
    currently loads and unloads the ISAPI extension each time it is
    requested, unless the ISAPICacheFile directive is specified.
    This is inefficient, but Apache's memory model makes this the
    most effective method. Many ISAPI modules are subtly
    incompatible with the Apache server, and unloading these
    modules helps to ensure the stability of the server.
    

    
    Also, remember that while Apache supports ISAPI Extensions,
    it does not support ISAPI Filters. Support for
    filters may be added at a later date, but no support is planned
    at this time.

    Programmer's Journal
    

    
    If you are programming Apache 2.0 mod_isapi
    modules, you must limit your calls to ServerSupportFunction
    to the following directives:
    

    
    
      
    HSE_REQ_SEND_URL_REDIRECT_RESP
    
      
    Redirect the user to another location.
    
      This must be a fully qualified URL (e.g.
      http://server/location).
    

      
    HSE_REQ_SEND_URL
    
      
    Redirect the user to another location.
    
      This cannot be a fully qualified URL, you are not allowed to
      pass the protocol or a server name (e.g. simply
      /location).
    
      This redirection is handled by the server, not the
      browser.
    
      
    Warning
    
        
    In their recent documentation, Microsoft appears to have
        abandoned the distinction between the two
        HSE_REQ_SEND_URL functions. Apache continues to treat
        them as two distinct functions with different requirements
        and behaviors.
    
      
    

      
    HSE_REQ_SEND_RESPONSE_HEADER
    
      
    Apache accepts a response body following the header if it
      follows the blank line (two consecutive newlines) in the
      headers string argument. This body cannot contain NULLs,
      since the headers argument is NULL terminated.
    

      
    HSE_REQ_DONE_WITH_SESSION
    
      
    Apache considers this a no-op, since the session will be
      finished when the ISAPI returns from processing.
    

      
    HSE_REQ_MAP_URL_TO_PATH
    
      
    Apache will translate a virtual name to a physical
      name.
    

      
    HSE_APPEND_LOG_PARAMETER
    
      
    
        This logged message may be captured in any of the following
        logs:

        

        
    The first option, the %{isapi-parameter}n component,
        is always available and preferred.
    
      
    

      
    HSE_REQ_IS_KEEP_CONN
    
      
    Will return the negotiated Keep-Alive status.
    

      
    HSE_REQ_SEND_RESPONSE_HEADER_EX
    
      
    Will behave as documented, although the fKeepConn
      flag is ignored.
    

      
    HSE_REQ_IS_CONNECTED
    
      
    Will report false if the request has been aborted.
    
    
    

    
    Apache returns FALSE to any unsupported call to
    ServerSupportFunction, and sets the
    GetLastError value to
    ERROR_INVALID_PARAMETER.
    

    
    ReadClient retrieves the request body exceeding the
    initial buffer (defined by ISAPIReadAheadBuffer). Based on the
    ISAPIReadAheadBuffer setting (number of bytes
    to buffer prior to calling the ISAPI handler) shorter requests are sent
    complete to the extension when it is invoked. If the request is
    longer, the ISAPI extension must use ReadClient to
    retrieve the remaining request body.
    

    
    WriteClient is supported, but only with the
    HSE_IO_SYNC flag or no option flag (value of
    0). Any other WriteClient request
    will be rejected with a return value of FALSE, and a
    GetLastError value of
    ERROR_INVALID_PARAMETER.
    

    
    GetServerVariable is supported, although extended server
    variables do not exist (as defined by other servers.) All the
    usual Apache CGI environment variables are available from
    GetServerVariable, as well as the ALL_HTTP
    and ALL_RAW values.
    

    
    Since httpd 2.0, mod_isapi supports additional
    features introduced in later versions of the ISAPI specification,
    as well as limited emulation of async I/O and the
    TransmitFile semantics. Apache httpd also supports preloading
    ISAPI .dlls for performance.

    概要
    


    
    このモジュールは非常に制限された条件下で、
    それぞれのリクエストに「すべて」のリクエストに対して
    一意に決まることが保証されている魔法のトークンを提供します。
    この一意な識別子は、適切に設定されたクラスタでは複数の
    マシンの間でさえも一意になります。それぞれのリクエストに対して環境変数
    UNIQUE_ID に識別子が設定されます。
    一意な識別子が便利な理由はいろいろありますが、
    このドキュメントの目的からは外れるため、ここでは説明しません。

    理論
    
    

    
    まずはじめに、Apache サーバが Unix
    マシンでどのように動作をするかを簡単に説明します。
    この機能は現時点では Windows NT ではサポートされていません。
    Unix マシンでは Apache はいくつかの子プロセスを作成し、
    その子プロセスが一つずつリクエストを処理します。それぞれの子プロセスは、
    生存期間中に複数のリクエストを扱うことができます。
    この議論では子プロセス間では一切データを共有しないことにします。
    以後、この子プロセスのことを httpd プロセス と呼びます。
    

    
    あなたのウェブサイトにはあなたが管理するいくつかのマシンがあるとします。
    それらをまとめてクラスタと呼ぶことにします。それぞれのマシンは複数の
    Apache を実行することもできます。
    これらすべてをまとめたものが「宇宙」であると考えられます。
    いくつかの仮定の下で、クラスタのマシン間がたくさん通信をすることなく、
    この宇宙の中でそれぞれのリクエストに一意な識別子を生成できることを示します。
    
    

    
    クラスタにあるマシンは以下の要求を見たさなければなりません。
    (マシンが一つだけだとしても、NTP で時計を合わせる方が良いです。)
    

    
      
      
    • NTP や他のネットワーク上で時間を合わせるプロトコルによって
      各マシンの時間の同期が取られていること。
      • 

      
    • モジュールがホスト名を引いて違う IP
      アドレスを受け取ることができるように、
      クラスタのそれぞれのマシンのホスト名が違うこと。
      • 
    
    

    
    オペレーティングシステムにおいては、pid (プロセス ID) が
    32 ビットの範囲内であることを仮定します。オペレーティングシステムの
    pid が 32 ビットを超える場合は、簡単な修正ではありますが、
    コードを変更する必要があります。
    

    
    これらの仮定が満たされていると、ある時点において、
    クラスタ内のどのマシンのどの httpd
    プロセスでも、一意に同定することができます。これはマシンの IP
    アドレスと httpd プロセスの pid で十分に行なうことができます。
    ですから、リクエストに一意な識別子を生成するためには、
    時刻を区別する必要があるだけです。
    

    
    時刻を区別するために、Unix のタイムスタンプ (UTC の 1970 年
    1 月 1 日からの秒数) と、16 ビットのカウンタを使います。
    タイムスタンプの粒度は一秒ですので、一秒間の 65536
    までの値を表現するためにカウンタを使用します。四つの値
    ( ip_addr, pid, time_stamp, counter ) で各 httpd
    プロセスで一秒の間に 65536 リクエストを数えあげることができます。
    時間が経つと pid が再利用されるという問題がありますが、
    この問題を解決するためにカウンタが使用されます。
    

    
    httpd の子プロセスが作成されると、カウンタは
    (その時点のマイクロ秒 ÷ 10) modulo 65536 で初期化されます
    (この式はいくつかのシステムにある、マイクロ秒の
    タイマの下位ビットが異なるという問題を解決するために選ばれました)。
    一意な識別子が生成されたとき、使用されるタイムスタンプは
    ウェブサーバにリクエストが到着した時刻になります。
    カウンタは識別子が生成されるたびに増加します 
    (あふれた場合は 0 に戻ります)。
    

    
    カーネルはプロセスをフォークすると、それぞれのプロセスのために
    pid を生成します。pid は繰り返されることが許可されています
    (pid の値は多くの Unix では 16 ビットですが、新しいシステムでは
    32 ビットに拡張されています)。
    ですから、ある程度の時間が経過すると同じ pid が再び使用されます。
    しかし、一秒内に再使用されなければ、
    四つの値の一意性は保たれます。つまり、我々はシステムが一秒間
    に 65536 個のプロセスを起動しないと仮定しています (いくつかの Unix
    では 32768 プロセスですが、それですらほとんどあり得ないでしょう)。
    

    
    何らかの理由で、同じ時刻が繰り返されたとしましょう。
    つまり、システムの時計が狂っていて、もう一度過去の時刻になってしまった
    (もしくは進みすぎていたときに、
    正しい時刻に戻したために再び将来の時刻になってしまった) とします。
    この場合、pid とタイムスタンプが再使用されることが簡単に示されます。
    カウンタ初期化用の関数は、この問題の回避を手助けしようと選択されています。
    本当はカウンタの初期化をするためにランダムな数字を使いたいのですが、
    ほとんどのシステムでは簡単に使用できる数は無いことに注意してください
    (すなわち、rand ()は使えません。rand () には seed
    を与える必要があり、seed には時刻を使えません。一秒単位では、
    その時刻はすでに繰り返されているからです)。
    これは、完璧な対策ではありません。
    

    
    この対策はどのくらい効果があるでしょうか?
    ここでは、マシン群の中の一つは最大で一秒に 500
    リクエストを扱うと仮定します (これを書いている時点では妥当な上限です。
    通常システムがすることは静的なファイルを取りだすだけではありませんから)。
    それを行なうために、そのマシンは並行して来るクライアントの数に
    応じた数の子プロセスを要求します。
    しかしながら、悲観的に考えて、一つの子プロセスが一秒に 500
    リクエストを扱えるとします。そうすると、(一秒の精度において)
    時刻が同じ時を繰り返すと、この子プロセスがカウンタの値を再び使い、
    一意性が壊れる可能性が 1.5% あります。
    これは非常に悲観的な例で、実世界の値では、ほとんど起こりそうにありません。
    それでもこれが起こる可能性のあるようなシステムなら、
    (プログラムコードを編集して) 
    カウンタを 32 ビットにするのが良いでしょう。
    
    

    
    サマータイムにより時計が「戻される」ことを気にしている人が
    いるかもしれません。ここで使用される時間は UTC であり、
    それは「常に」進むのでここでは問題になりません。x86 上の Unix
    はこの条件を満たすために適切な設定が必要かもしれないことに
    注意してください。マザーボードの時計は UTC になっていて、
    他の時間はそこから適切に補正されることを仮定できるように
    設定されなければなりません。そのような場合でさえ、NTP
    を使っているならばリブート後にすぐ正しい UTC の時間になるでしょう。
    

    
    UNIQUE_ID 環境変数は 112 ビット (32 ビット IP
    アドレス、32 ビット pid, 32 ビットタイムスタンプ、16
    ビットカウンタの四つの組) をアルファベット [A-Za-z0-9@-]
    を用いて MIME の base64 符号化と同様の方法により符号化し、19
    の文字を生成することにより作成されます。MIME の base64
    のアルファベットは実際は [A-Za-z0-9+/] ですが、
    + と / とは URL
    では特別な符号化が必要なので、あまり望ましくありません。
    全ての値はネットワークバイトオーダで符号化されますので、
    符号は違ったバイトオーダのアーキテクチャ間で比較可能です。
    実際の符号化の順番は: タイムスタンプ、IP アドレス、pid,
    カウンタです。この順には目的がありますが、
    アプリケーションは符号を解析するべきではないことを強調しておきます。
    アプリケーションは符号化された UNIQUE_ID
    全体を透過的なトークンとして扱うべきです。
    UNIQUE_ID は他の UNIQUE_ID
    との等価性を調べるためだけにのみ使用できます。
    

    
    この順番は将来、既存の UNIQUE_ID
    のデータベースとの衝突を心配することなく符号を変更することが
    可能になるように選択しています。
    新しい符号はタイムスタンプを最初の要素として残すのが望ましく、
    それ以外は同じアルファベットとビット長を使うことができます。
    タイムスタンプは本質的に増加系列ですので、
    クラスタの全てのマシンがリクエストとサーバ機能を停止して、
    古い符号化方式を使用するのをやめるフラグ秒があれば十分です。
    その後は、リクエストを再開し、
    新しい符号を発行することができるようになります。
    

    
    我々はこれが、
    この問題に対する比較的移植性の高い解決法だと考えています。
    Windows NT のようなマルチスレッドのシステムに拡張することができますし、
    将来必要になればさらに増やすこともできます。
    ID は必要に応じて長くすることができますので、生成された ID
    は実質上、無限に有効です。また、クラスタのマシン間の通信も事実上必要なく
    (NTP による同期のみが必要で、これはオーバヘッドはあまりありません)、httpd
    プロセス間の通信も必要ありません (通信はカーネルにより割り当てられた
    pid の値により暗黙の内に行なわています)。
    さらに限られた状況下では、ID はさらに短くすることができますが、
    より多くの情報を仮定する必要がでてきます (例えば、32 ビット
    IP アドレスはどのサイトにおいても過剰な情報ですが、
    それの代わりになる移植性のあるものはありません)。

    概要
    

    
    mod_info を設定するには、以下を httpd.conf
    ファイルに加えます。
    

    
    
      <Location /server-info>
    
      
        SetHandler server-info
    
          
      </Location>
    
    

    
    <Location>
    の中で mod_access を使って、サーバ設定情報への
    アクセスを制限したいと思うかもしれません :
    

    
    
      <Location /server-info>
    
      
        SetHandler server-info
    
        Order deny,allow
    
        Deny from all
    
        Allow from yourcompany.com
    
          
      </Location>
    
    

    
    一旦設定すると、http://your.host.example.com/server-info
    にアクセスすることでサーバの情報を得られるようになります。

    Security Issues
    
    
    一旦 mod_info がサーバに読み込まれると、
    提供しているハンドラ機能はディレクトリ毎の設定ファイル (例えば
    .htaccess) を含む すべての設定ファイルで有効になります。
    このモジュールを有効にするときはセキュリティの問題を考慮する必要が
    あるでしょう。
    

    
    特に、このモジュールはシステムパス、ユーザ名/パスワード、
    データベース名など、他の Apache モジュールの設定ディレクティブから
    セキュリティ上微妙な情報を漏らす可能性があります。
    ですから、このモジュールはきちんとアクセス制御された環境でのみ、
    注意して使ってください。
    

    
    設定情報へのアクセスを制限するために、mod_authz_host を
    使うのが良いでしょう。
    
      
    
    アクセス制御
    
      <Location /server-info>
    
      
        SetHandler server-info
    
        Order allow,deny
    
        # Allow access from server itself
    
        Allow from 127.0.0.1
    
        # Additionally, allow access from local workstation
    
        Allow from 192.168.1.17
    
          
      </Location>

    表示される情報の選択
    
    
    デフォルトでは、サーバ情報はすべての有効なモジュールと、
    各モジュールについて、モジュールが理解するディレクティブ、
    実装している、フック、現時点での設定の関連するディレクティブに
    なっています。
    

    
    server-info リクエストへクエリーを追加することで、
    設定情報の他の表示形式を選ぶことができます。例えば、
    http://your.host.example.com/server-info?config は
    すべての設定ディレクティブを表示します。
    
    
    
    
        
    ?<module-name>
    
            
    指定されたモジュールに関連する情報のみ
    
        
    ?config
    
            
    モジュールでソートせずに、設定ディレクティブのみ
    
        
    ?hooks
    
            
    各モジュールが使用するフックのみ
    
        
    ?list
    
            
    有効なモジュールの簡単なリストのみ
    
        
    ?server
    
            
    基本サーバ情報のみ

    既知の制限
    
    
    mod_info は、元の設定ファイルを読むのではなく、
    既にパースされた設定を読み込むことで情報を提供します。従って、
    パース済みの設定情報の木が生成される方法による制限がいくつかあります:
    
    
      
      
    • パースされた設定に保存されずに、すぐに実行されるディレクティブは
          一覧に現れません。これには
          ServerRoot,
          LoadModule,
          LoadFile があります。
      • 
      
    • Include,
          <IfModule>,
          <IfDefine>,
          のような設定ファイル自身を制御するディレクティブは表示されません。
          そのディレクティブの中にあり、有効になっているディレクティブは
          表示されます。
      • 
      
    • コメントは表示されません。(これは仕様だと思ってください。)
      • 
      
    • .htaccess ファイルの設定ディレクティブは表示されません
          (永久的なサーバ設定の一部ではないからです)。
      • 
      
    • <Directory>
          のようなコンテナディレクティブは普通に表示されますが、
          mod_info は閉じタグの </Directory> などの数を知ることはできません。
      • 
      
    • mod_perl のようなサードパーティモジュール
           のディレクティブは表示されないかもしれません。

    Module Apache mod_ldap
    

    

    Langues Disponibles:  en  |

    Description:Conservation des connexions LDAP et services de mise en
cache du résultat à destination des autres modules LDAP
    

    Statut:Extension
    

    Identificateur de Module:ldap_module
    

    Fichier Source:util_ldap.c
    

    Sommaire
    

    
    Ce module a été conçu dans le but d'améliorer les performances
    des sites web s'appuyant sur des connexions en arrière-plan vers des
    serveurs LDAP. Il ajoute aux fonctions fournies par les
    bibliothèques standards LDAP la conservation des connexions LDAP
    ainsi qu'un cache LDAP partagé en mémoire.
    

    
    Pour activer ce module, le support LDAP doit être compilé dans
    apr-util. Pour ce faire, on ajoute l'option --with-ldap
    au script configure lorsqu'on construit
    Apache.
    

    
    Le support SSL/TLS est conditionné par le kit de développement
    LDAP qui a été lié à APR. Au moment où ces
    lignes sont écrites, APR-util supporte OpenLDAP SDK (version 2.x ou
    supérieure), Novell LDAP
    SDK, 
    Mozilla LDAP SDK, le SDK LDAP Solaris natif (basé sur Mozilla)
    ou le SDK LDAP Microsoft natif. Voir le site web APR pour plus de détails.

    Conservation des connexions LDAP
    

    
    Les connexions LDAP sont conservées de requête en requête. Ceci
    permet de rester connecté et identifié au serveur LDAP, ce dernier
    étant ainsi prêt pour la prochaine requête, sans avoir à se
    déconnecter, reconnecter et réidentifier. Le gain en performances
    est similaire à celui des connexions persistantes (keepalives)
    HTTP.
    

    
    Sur un serveur très sollicité, il est possible que de nombreuses
    requêtes tentent d'accéder simultanément à la même connexion au
    serveur LDAP. Lorsqu'une connexion LDAP est utilisée, Apache en crée
    une deuxième en parallèle à la première, ce qui permet d'éviter que
    le système de conservation des connexions ne devienne un goulot
    d'étranglement.
    

    
    Il n'est pas nécessaire d'activer explicitement la conservation
    des connexions dans la configuration d'Apache. Tout module utilisant
    le module ldap pour accéder aux services LDAP partagera le jeu de
    connexions.
    

    
    Les connexions LDAP peuvent garder la trace des données
    d'identification du client ldap utilisées pour l'identification
    auprès du serveur LDAP. Ces données peuvent être fournies aux
    serveurs LDAP qui ne permettent pas les connexions anonymes au cours
    lors des tentatives de sauts vers des serveurs alternatifs. Pour
    contrôler cette fonctionnalité, voir les directives LDAPReferrals et LDAPReferralHopLimit. Cette
    fonctionnalité est activée par défaut.

    Cache LDAP
    

    
    Pour améliorer les performances, mod_ldap met en oeuvre
    une stratégie de mise en cache agressive visant à minimiser le nombre de
    fois que le serveur LDAP doit être contacté. La mise en cache peut
    facilement doubler et même tripler le débit d'Apache lorsqu'il sert des
    pages protégées par mod_authnz_ldap. De plus, le serveur
    LDAP verra lui-même sa charge sensiblement diminuée.
    

    
    mod_ldap supporte deux types de mise en cache
    LDAP : un cache recherche/identification durant la phase
    de recherche/identification et deux caches d'opérations
    durant la phase de comparaison. Chaque URL LDAP utilisée par le
    serveur a son propre jeu d'instances dans ces trois caches.
    

    
    Le cache
    recherche/identification
    
      
    Les processus de recherche et d'identification sont les
      opérations LDAP les plus consommatrices en temps, en particulier
      si l'annuaire est de grande taille. Le cache de
      recherche/identification met en cache toutes les recherches qui
      ont abouti à une identification positive. Les résultats négatifs
      (c'est à dire les recherches sans succès, ou les recherches qui
      n'ont pas abouti à une identification positive) ne sont pas mis en
      cache. La raison de cette décision réside dans le fait que les
      connexions avec des données d'identification invalides ne
      représentent qu'un faible pourcentage du nombre total de
      connexions, et ainsi, le fait de ne pas mettre en cache les
      données d'identification invalides réduira d'autant la taille du
      cache.
    

      
    mod_ldap met en cache le nom d'utilisateur, le
      DN extrait, le mot de passe utilisé pour l'identification, ainsi
      que l'heure de l'identification. Chaque fois qu'une nouvelle
      connexion est initialisée avec le même nom d'utilisateur,
      mod_ldap compare le mot de passe de la nouvelle
      connexion avec le mot de passe enregistré dans le cache. Si les
      mots de passe correspondent, et si l'entrée du cache n'est pas
      trop ancienne, mod_ldap court-circuite la phase
      de recherche/identification.
    

      
    Le cache de recherche/identification est contrôlé par les
      directives LDAPCacheEntries et LDAPCacheTTL.
    
    

    
    Les caches d'opérations
    
      
    Au cours des opérations de comparaison d'attributs et de noms
      distinctifs (DN), mod_ldap utilise deux caches
      d'opérations pour mettre en cache les opérations de comparaison.
      Le premier cache de comparaison sert à mettre en cache les
      résultats de comparaisons effectuées pour vérifier l'appartenance
      à un groupe LDAP. Le second cache de comparaison sert à mettre en
      cache les résultats de comparaisons entre DNs.
    

      
    Notez que, lorsque l'appartenance à un groupe est vérifiée,
      toute comparaison de sous-groupes est mise en cache afin
      d'accélérer les comparaisons de sous-groupes ultérieures.
    

      
    Le comportement de ces deux caches est contrôlé par les
      directives LDAPOpCacheEntries et LDAPOpCacheTTL.
    
    

    
    Superviser le cache
    
      
    mod_ldap possède un gestionnaire de contenu
      qui permet aux administrateurs de superviser les performances du
      cache. Le nom du gestionnaire de contenu est
      ldap-status, et on peut utiliser les directives
      suivantes pour accéder aux informations du cache de
      mod_ldap :
    

      
    <Location "/server/cache-info">
    SetHandler ldap-status
</Location>
    


      
    En se connectant à l'URL
      http://nom-serveur/infos-cache, l'administrateur peut
      obtenir un rapport sur le statut de chaque cache qu'utilise
      mod_ldap. Notez que si Apache ne supporte pas la
      mémoire partagée, chaque instance de httpd
      possèdera son propre cache, et chaque fois que l'URL sera
      rechargée, un résultat différent pourra être affiché, en fonction
      de l'instance de httpd qui traitera la
      requête.

    Utiliser SSL/TLS
    

    
    La possibilité de créer des connexions SSL et TLS avec un serveur
    LDAP est définie par les directives 
    LDAPTrustedGlobalCert, 
    LDAPTrustedClientCert et 
    LDAPTrustedMode. Ces directives permettent de spécifier
    l'autorité de certification (CA), les certificats clients éventuels,
    ainsi que le type de chiffrement à utiliser pour la connexion (none,
    SSL ou TLS/STARTTLS).
    

    
    # Etablissement d'une connexion SSL LDAP sur le port 636.
# Nécessite le chargement de mod_ldap et mod_authnz_ldap.
# Remplacez "votre-domaine.example.com" par le nom de votre
# domaine.

    Certificats SSL/TLS
    

    
    Les différents SDKs LDAP disposent de nombreuses méthodes pour
    définir et gérer les certificats des clients et des autorités de
    certification (CA).
    

    
    Si vous avez l'intention d'utiliser SSL ou TLS, lisez cette
    section ATTENTIVEMENT de façon à bien comprendre les différences de
    configurations entre les différents SDKs LDAP supportés.
    

    
    SDK Netscape/Mozilla/iPlanet
    
        
    Les certificat de CA sont enregistrés dans un fichier nommé
	cert7.db. Le SDK ne dialoguera avec aucun serveur LDAP dont le
	certificat n'a pas été signé par une CA spécifiée dans ce
	fichier. Si des certificats clients sont requis, un fichier
	key3.db ainsi qu'un mot de passe optionnels peuvent être
	spécifiés. On peut aussi spécifier le fichier secmod si
	nécessaire. Ces fichiers sont du même format que celui utilisé
	par les navigateurs web Netscape Communicator ou Mozilla. Le
	moyen le plus simple pour obtenir ces fichiers consiste à les
	extraire de l'installation de votre navigateur.
    

	
    Les certificats clients sont spécifiés pour chaque connexion en
	utilisant la directive LDAPTrustedClientCert et en se référant au
	certificat "nickname". On peut éventuellement spécifier un mot de passe
	pour déverrouiller la clé privée du certificat.
    

        
    Le SDK supporte seulement SSL. Toute tentative d'utilisation
	de STARTTLS engendrera une erreur lors des tentatives de
	contacter le serveur LDAP pendant l'exécution.
    

        
    # Spécifie un fichier de certificats de CA Netscape
LDAPTrustedGlobalCert CA_CERT7_DB "/certs/cert7.db"
# Spécifie un fichier key3db optionnel pour le support des
# certificats clients
LDAPTrustedGlobalCert CERT_KEY3_DB "/certs/key3.db"
# Spécifie le fichier secmod si nécessaire
LDAPTrustedGlobalCert CA_SECMOD "/certs/secmod"
<Location "/ldap-status">
    SetHandler ldap-status

    Require host yourdomain.example.com

    AuthLDAPURL "ldaps://127.0.0.1/dc=example,dc=com?uid?one"
    Require valid-user
</Location>
    


    

    
    SDK Novell
    

        
    Un ou plusieurs certificats de CA doivent être spécifiés pour
	que le SDK Novell fonctionne correctement. Ces certificats
	peuvent être spécifiés sous forme de fichiers au format binaire
	DER ou codés en Base64 (PEM).
    

	
    Note: Les certificats clients sont spécifiés globalement plutôt qu'à
	chaque connexion, et doivent être spécifiés à l'aide de la directive
	LDAPTrustedGlobalCert comme
	ci-dessous. Définir des certificats clients via la directive LDAPTrustedClientCert engendrera une
	erreur qui sera journalisée, au moment de la tentative de connexion avec
	le serveur LDAP.
    

	
    Le SDK supporte SSL et STARTTLS, le choix étant défini par le
	paramètre de la directive LDAPTrustedMode. Si une URL de type
	ldaps:// est spécifiée, le mode SSL est forcé, et l'emporte sur cette
	directive.
    

        
    # Spécifie deux fichiers contenant des certificats de CA
LDAPTrustedGlobalCert CA_DER "/certs/cacert1.der"
LDAPTrustedGlobalCert CA_BASE64 "/certs/cacert2.pem"
# Spécifie un fichier contenant des certificats clients
# ainsi qu'une clé
LDAPTrustedGlobalCert CERT_BASE64 "/certs/cert1.pem"
LDAPTrustedGlobalCert KEY_BASE64 "/certs/key1.pem" [password]
# N'utilisez pas cette directive, sous peine de provoquer
# une erreur
#LDAPTrustedClientCert CERT_BASE64 "/certs/cert1.pem"
    


    

    
    SDK OpenLDAP
    

        
    Un ou plusieurs certificats de CA doivent être spécifiés pour
	que le SDK OpenLDAP fonctionne correctement. Ces certificats
	peuvent être spécifiés sous forme de fichiers au format binaire
	DER ou codés en Base64 (PEM).
    

        
    Les certificats clients et CA peuvent être spécifiés globalement
	(LDAPTrustedGlobalCert) ou pour
	chaque connexion (LDAPTrustedClientCert). Les définitions au
	niveau d'une connexion l'emportent sur les définitions globales.
    

        
    La documentation du SDK prétend que SSL et STARTTLS sont
	supportés ; cependant, STARTTLS semble ne pas fonctionner avec
	toutes les versions du SDK. Le mode SSL/TLS peut être défini en
	utilisant le paramètre de la directive LDAPTrustedMode. Si une
	URL de type
	ldaps:// est spécifiée, le mode SSL est forcé. La documentation
	OpenLDAP indique que le support SSL (ldaps://) tend à être
	remplacé par TLS, bien que le mode SSL fonctionne toujours.

    SDK Solaris
    

        
    SSL/TLS pour les bibliothèques LDAP propres à Solaris n'est
	pas encore supporté. Si nécessaire, installez et utilisez plutôt
	les bibliothèques OpenLDAP.
    

    

    
    SDK Microsoft
    

        
    La configuration des certificats SSL/TLS pour les
	bibliothèques LDAP propres à Microsoft s'effectue à l'intérieur
	du registre système, et aucune directive de configuration n'est
	requise.

    Compatibilité:Disponible à partir de la version 2.3.12 du serveur HTTP
Apache
    

    
    
    Cette directive permet de spécifier la durée maximale, en
    secondes, pendant laquelle une connexion LDAP du jeu de connexions
    peut demeurer inactive, mais rester quand-même disponible pour une
    utilisation éventuelle. Le jeu de connexions est nettoyé au fur et à
    mesure des besoins, de manière non asynchrone.
    

    
    Si cette directive est définie à 0, les connexions ne sont jamais
    sauvegardées dans le jeu de connexions d'arrière-plan. Avec la
    valeur par défaut -1, ou toute autre valeur négative, les connexions
    peuvent être réutilisées sans limite de durée.
    

    
    Dans le but d'améliorer les performances, le temps de référence
    qu'utilise cette directive correspond au moment où la connexion LDAP
    est enregistrée ou remise dans le jeu de connexions, et non au
    moment du dernier échange réussi avec le serveur LDAP.
    

    
    La version 2.4.10 a introduit de nouvelles mesures permettant
    d'éviter une augmentation excessive du temps de référence due à des
    correspondances positives dans le cache ou des requêtes lentes. A
    cet effet, le temps de référence n'est pas réactualisé si aucune
    connexion LDAP d'arrière-plan n'est requise ; d'autre part, le temps
    de référence se base sur le moment où la requête HTTP est reçue, et
    non sur le moment où la requête a été traitée.
    

    
    Cette durée de vie s'exprime par défaut en secondes, mais
    il est possible d'utiliser d'autres unités en ajoutant un suffixe :
    millisecondes (ms), minutes (min), ou heures (h).

    Cette directive configure l'option LDAP_OPT_NETWORK_TIMEOUT (ou
    LDAP_OPT_CONNECT_TIMEOUT) dans la bibliothèque client LDAP
    sous-jacente, si elle est disponible. Cette valeur représente la
    durée pendant laquelle la bibliothèque client LDAP va attendre que
    le processus de connexion TCP au serveur LDAP soit achevé.
    

    
    Si la connexion n'a pas réussi avant ce délai, une erreur sera
    renvoyée, ou la bibliothèque client LDAP tentera de se connecter à
    un second serveur LDAP, s'il en a été défini un (via une liste de
    noms d'hôtes séparés par des espaces dans la directive AuthLDAPURL).
    

    
    La valeur par défaut est 10 secondes, si la bibliothèque client
    LDAP liée avec le serveur supporte l'option
    LDAP_OPT_NETWORK_TIMEOUT.
    

    
    LDAPConnectionTimeout n'est disponible que si la bibliothèque client
    LDAP liée avec le serveur supporte l'option
    LDAP_OPT_NETWORK_TIMEOUT (ou LDAP_OPT_CONNECT_TIMEOUT), et le
    comportement final est entièrement dicté par la bibliothèque client
    LDAP.

    Active les options de débogage LDAP spécifiques au SDK, qui
    entraînent en général une journalisation d'informations verbeuses du
    SDK LDAP dans le journal principal des erreurs d'Apache. Les
    messages de traces en provenance du SDK LDAP fournissent des
    informations très détaillées qui peuvent s'avérer utiles lors du
    débogage des problèmes de connexion avec des serveurs LDAP
    d'arrière-plan.
    

    
    Cette option n'est configurable que lorsque le serveur HTTP
    Apache est lié avec un SDK LDAP qui implémente
    LDAP_OPT_DEBUG ou LDAP_OPT_DEBUG_LEVEL,
    comme OpenLDAP (une valeur de 7 est verbeuse) ou Tivoli Directory
    Server (une valeur de 65535 est verbeuse).
    

    
    
    
    Les informations journalisées peuvent contenir des données
    d'authentification en clair utilisées ou validées lors de
    l'authentification LDAP ; vous devez donc prendre soin de protéger
    et de purger le journal des erreurs lorsque cette directive est
    utilisée.

    Compatibilité:Le paramètre default est disponible depuis la
version 2.4.7 du serveur HTTP Apache.
    

    
    
    Certains serveurs LDAP partagent leur annuaire en plusieurs
    domaines et utilisent le système des redirections (referrals) pour
    aiguiller un client lorsque les limites d'un domaine doivent être
    franchies. Ce processus est similaire à une redirection HTTP. Les
    bibliothèques client LDAP ne respectent pas forcément ces
    redirections par défaut. Cette directive permet de configurer
    explicitement les redirections LDAP dans le SDK sous-jacent.
    

    
    La directive LDAPReferrals accepte les
    valeurs suivantes :
    

    
    
     
    "on"
    
     
     
    Avec la valeur "on", la prise en compte des redirections LDAP par
     le SDK sous-jacent est activée, la directive LDAPReferralHopLimit permet de surcharger la
     "hop limit" du SDK, et un "LDAP rebind callback" est enregistré.
    
     
    "off"
    
     
     
    Avec la valeur "off", la prise en compte des redirections
     LDAP par le SDK sous-jacent est complètement désactivée.
    
     
    "default"
    
     
     
    Avec la valeur "default", la prise en compte des redirections LDAP
     par le SDK sous-jacent n'est pas modifiée, la directive LDAPReferralHopLimit ne permet pas de
     surcharger la "hop limit" du SDK, et aucun "LDAP rebind callback" n'est
     enregistré.
    
    
    
    
    
    La directive LDAPReferralHopLimit travaille en conjonction
    avec cette directive pour limiter le nombre de redirections à suivre pour
    achever le traitement de la requête LDAP.  Lorsque le processus de
    redirection est activé par la valeur "On", les données d'authentification du
    client sont transmises via un "rebind callback" à tout serveur LDAP qui en
    fait la demande.

    Lorsque le délai est atteint, httpd va refaire un essai dans le
    cas où une connexion existante a été silencieusement fermée par un
    pare-feu. Les performances seront cependant bien meilleures si le
    pare-feu est configuré pour envoyer des paquets TCP RST au lieu de
    rejeter silencieusement les paquets.
    

    
    
    
    Les délais pour les opérations de comparaison LDAP nécessitent un

    概要
    

    
    このモジュールは Allow や Deny ディレクティブを無視しますので、
    注意して使って下さい。クライアントのホスト名、アドレスや環境変数を使って
    アクセスを制限したいコンテンツに対してはキャッシュ機能を有効にするべきではありません。
    
    

    
    mod_cache はローカルのコンテンツやプロキシされた
    コンテンツをキャッシュするために使われる RFC 2616 準拠の
    HTTP コンテンツキャッシュを実装しています。mod_cache
    の動作にはストレージを管理するモジュールが必要です。標準
    Apache 配布には二つストレージ管理モジュールが含まれています:
    
    
    
    
    
    mod_cache_disk
    
    
    ディスクを使用したストレージ管理機構を実装しています。
    

    
    mod_mem_cache
    
    
    メモリを使用したストレージ管理機構を実装しています。
    mod_mem_cache は次の二つのモードのどちらかで動作する
    ように設定できます: オープンされているファイル記述子をキャッシュするモードか、
    ヒープ上でのオブジェクトの自体をキャッシュをするモードです。
    mod_mem_cache はローカルで生成されるコンテンツや、
    mod_proxy が
    ProxyPass を使って設定されている
    ときの (つまりリバースプロキシ での) バックエンドサーバの
    コンテンツをキャッシュするのに使えます。
    
    
    

    
    コンテンツのキャッシュへの保存と取得は URI に基づいたキーが使われます。
    アクセス保護のかけられているコンテンツはキャッシュされません。

    CacheEnable ディレクティブで mod_cache 
    モジュールが url-string 以下の URL をキャッシュするようにします。
    キャッシュストレージ管理方式は cache_type 引数で指定します。
    cache_type  mem で、
    mod_mem_cache で実装されているメモリを使ったストレージ
    管理方式を使うように mod_cache に指示します。
    cache_type disk で、

    管理を使うように mod_cache に指示します。
    cache_type fd は mod_cache に
    mod_mem_cache により実装されているファイル記述子の
    キャッシュを使うように指示します。
    

    
    (下の例のように) CacheEnable ディレクティブの
    URL 空間が重複しているときは、該当するストレージ方式を順に試して、
    実際にリクエストの処理ができると、その方式で処理します。
    ストレージ管理方式が実行される順番は設定ファイル中の
    CacheEnable の順番により決定されます。

    RFC 2616 によると、hop-by-hop HTTP ヘッダはキャッシュには保管されません。
    以下のヘッダは hop-by-hop ヘッダに該当しますので、
    CacheIgnoreHeaders
    の設定に関係なくキャッシュには保管されません:

    CacheIgnoreHeaders で
    キャッシュに保管しない追加の HTTP ヘッダを指定します。
    例えば、クッキーをキャッシュに保管しないようにした方がよい場合も
    あるでしょう。
    

    
    CacheIgnoreHeaders の引数は、
    キャッシュに保管しない HTTP ヘッダを空白区切りにしたリスト形式です。
    キャッシュに保管しないヘッダが hop-by-hop ヘッダだけの場合
    (RFC 2616 準拠の動作のとき) は、
    CacheIgnoreHeaders を None
    に設定できます。
    

    
    例 1
    
      CacheIgnoreHeaders Set-Cookie
    
    

    
    例 2
    
      CacheIgnoreHeaders None
    
    

    
    警告:
    
      Expires のような適切のキャッシュ管理のために必要な

    CacheIgnoreQueryString ディレクティブを使うと
    有効期限が指定されていなくてもキャッシュしますし、
    クエリーストリングが異なっていてもキャッシュを返します。
    このディレクティブが有効になっている場合、キャッシュ機能の側面からみると、

    計算するようにできます。有効期限を次の計算式に従って生成するのですが、
    そのときに使われる factor を
    CacheLastModifiedFactor ディレクティブで指定します。
    
    

    
    expiry-period = time-since-last-modified-date * factor
    expiry-date = current-date + expiry-period
    

    
    例えば、ドキュメントが 10 時間前に最後に修正されていて、
    factor が 0.1 であれば、期日は 10*0.1 = 1 時間に
    設定されます。現在時刻が 3:00pm であれば、計算された期日は
    3:00pm + 1hour = 4:00pm になります。
    

    
    期日が CacheMaxExpire で設定されている値
    より大きくなってしまっている場合は、CacheMaxExpire
    の設定値が優先されます。

    Apache MPM netware

    Description:Multi-Processing Module implementing an exclusively threaded web
    server optimized for Novell NetWare
    

    Status:MPM
    

    Module Identifier:mpm_netware_module
    

    Source File:mpm_netware.c
    

    Summary
    

    
    This Multi-Processing Module (MPM) implements an exclusively
    threaded web server that has been optimized for Novell
    NetWare.
    

    
    The main thread is responsible for launching child
    worker threads which listen for connections and serve them when they
    arrive. Apache HTTP Server always tries to maintain several spare
    or idle worker threads, which stand ready to serve incoming
    requests. In this way, clients do not need to wait for a new
    child threads to be spawned before their requests can be
    served.
    

    
    The StartThreads,
    MinSpareThreads,
    MaxSpareThreads, and
    MaxThreads
    regulate how the main thread creates worker threads to serve
    requests. In general, Apache httpd is very self-regulating, so most
    sites do not need to adjust these directives from their default
    values. Sites with limited memory may need to decrease MaxThreads to keep the server from
    thrashing (spawning and terminating idle threads). More information
    about tuning process creation is provided in the performance hints
    documentation.
    

    
    MaxConnectionsPerChild
    controls how frequently the server recycles processes by killing old
    ones and launching new ones. On the NetWare OS it is highly
    recommended that this directive remain set to 0. This allows worker
    threads to continue servicing requests indefinitely.

    MaxThreads Directive
    

    

    Description:Set the maximum number of worker threads
    

    Syntax:MaxThreads number
    

    Default:MaxThreads 2048
    

    Context:server config
    

    Status:MPM
    

    Module:mpm_netware
    

    
    
    The MaxThreads directive sets the desired
    maximum number worker threads allowable. The default value is
    also the compiled in hard limit. Therefore it can only be lowered,
    for example:
    

    
    
      MaxThreads 512

mod_authz_groupfile - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Apache Module mod_authz_groupfile
    

    

    Available Languages:  en  |
 fr  |
 ja  |
 ko 
    

    

    Description:Group authorization using plaintext files
    

    Status:Base
    

    Module Identifier:authz_groupfile_module
    

    Source File:mod_authz_groupfile.c
    

    Compatibility:Available in Apache 2.1 and later
    

    Summary
    

    
    This module provides authorization capabilities so that
    authenticated users can be allowed or denied access to portions
    of the web site by group membership. Similar functionality is
    provided by mod_authz_dbm.
    

    


    top
    

    

    The Require Directives
    

    
    Apache's Require
    directives are used during the authorization phase to ensure that
    a user is allowed to access a resource.  mod_authz_groupfile extends the
    authorization types with group and group-file.
    
    

    
    Since v2.4.8, expressions are supported
    within the groupfile require directives.
    


    Require group
    

    
    This directive specifies group membership that is required for the
    user to gain access.
    

    
    Require group admin
    





    Require file-group
    

    
    When this directive is specified, the filesystem permissions on
    the file being accessed are consulted. The user must be a member of
    a group with the same name as the group that owns the file.
    See mod_authz_owner for more
    details.
    

    
    Require file-group
    





    

    top
    

    AuthGroupFile Directive
    

    

    Description:Sets the name of a text file containing the list
of user groups for authorization
    

    Syntax:AuthGroupFile file-path
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Base
    

    Module:mod_authz_groupfile
    

    
    
    The AuthGroupFile directive sets the
    name of a textual file containing the list of user groups for user
    authorization. File-path is the path to the group
    file. If it is not absolute, it is treated as relative to the ServerRoot.
    

    
    Each line of the group file contains a groupname followed by a
    colon, followed by the member usernames separated by spaces.
    

    
    Example:
    
      mygroup: bob joe anne
    
    

    
    Note that searching large text files is very
    inefficient; AuthDBMGroupFile provides a much better performance.
    

    
    Security
    
      
    Make sure that the AuthGroupFile is
      stored outside the document tree of the web-server; do not
      put it in the directory that it protects. Otherwise, clients may
      be able to download the AuthGroupFile.

mod_slotmem_plain - Apache HTTP Server Version 2.4

    Apache Module mod_slotmem_plain
    

    

    Available Languages:  en  |

    Description:Slot-based shared memory provider.
    

    Status:Extension
    

    Module Identifier:slotmem_plain_module
    

    Source File:mod_slotmem_plain.c
    

    Summary
    

    
    mod_slotmem_plain is a memory provider which
    provides for creation and access to a plain memory segment
    in which the datasets are organized in "slots."
    
    

    
    If the memory needs to be shared between threads and
    processes, a better provider would be
    mod_slotmem_shm.
    
    

    
    mod_slotmem_plain provides the following API functions:
    
    


    /* call the callback on all worker slots */
apr_status_t doall(ap_slotmem_instance_t *s, ap_slotmem_callback_fn_t *func, void *data, apr_pool_t *pool)

/* create a new slotmem with each item size is item_size */
apr_status_t create(ap_slotmem_instance_t **new, const char *name, apr_size_t item_size, unsigned int item_num, ap_slotmem_type_t type, apr_pool_t *pool)

/* attach to an existing slotmem */
apr_status_t attach(ap_slotmem_instance_t **new, const char *name, apr_size_t *item_size, unsigned int *item_num, apr_pool_t *pool)

/* get the direct pointer to the memory associated with this worker slot */
apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void **mem)

/* get/read the memory from this slot to dest */
apr_status_t get(ap_slotmem_instance_t *s, unsigned int item_id, unsigned char *dest, apr_size_t dest_len)

/* put/write the data from src to this slot */
apr_status_t put(ap_slotmem_instance_t *slot, unsigned int item_id, unsigned char *src, apr_size_t src_len)

/* return the total number of slots in the segment */
unsigned int num_slots(ap_slotmem_instance_t *s)

/* return the total data size, in bytes, of a slot in the segment */
apr_size_t slot_size(ap_slotmem_instance_t *s)

/* grab or allocate the first free slot and mark as in-use (does not do any data copying) */
apr_status_t grab(ap_slotmem_instance_t *s, unsigned int *item_id)

/* forced grab or allocate the specified slot and mark as in-use (does not do any data copying) */
apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id)

/* release or free a slot and mark as not in-use (does not do any data copying) */
apr_status_t release(ap_slotmem_instance_t *s, unsigned int item_id)

    Apache Module mod_dav_lock
    

    

    Available Languages:  en  |

 ja 
    

    

    Description:Generic locking module for mod_dav
    

    Status:Extension
    

    Module Identifier:dav_lock_module
    

    Source File:mod_dav_lock.c
    

    Compatibility:Available in version 2.1 and later
    

    Summary
    

    
    This module implements a generic locking API which can be used by any
    backend provider of mod_dav. It requires at least
    the service of mod_dav. But without a backend provider
    which makes use of it, it's useless and should not be loaded into the
    server. A sample backend module which actually utilizes
    mod_dav_lock is mod_dav_svn, the subversion provider module.
    

    
    Note that mod_dav_fs does not need this
    generic locking module, because it uses its own more specialized
    version.
    

    
    In order to make mod_dav_lock functional, you just have
    to specify the location of the lock database using the DavGenericLockDB directive described
    below.
    

    
    Developer's Note
    
      
    In order to retrieve the pointer to the locking provider function, you
      have to use the ap_lookup_provider API with the arguments
      dav-lock, generic, and 0.
    
    
    

    



    top
    

    DavGenericLockDB Directive
    

    

    Description:Location of the DAV lock database
    

    Syntax:DavGenericLockDB file-path
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_dav_lock
    

    
    
    Use the DavGenericLockDB directive to specify
    the full path to the lock database, excluding an extension. If
    the path is not absolute, it will be interpreted relative to ServerRoot. The implementation of
    mod_dav_lock uses a SDBM database to track user
    locks.
    

    
    Example
    DavGenericLockDB var/DavLock
    

    

    
    The directory containing the lock database file must be
    writable by the User
    and Group under which
    Apache is running.  For security reasons, you should create a
    directory for this purpose rather than changing the permissions on
    an existing directory.  In the above example, Apache will create
    files in the var/ directory under the ServerRoot with the base filename
    DavLock and an extension added by the server.

    説明:マルチスレッドとマルチプロセスのハイブリッド型
ウェブサーバを実装したマルチプロセッシングモジュール
    

    ステータス:MPM
    

    モジュール識別子:mpm_worker_module
    

    ソースファイル:worker.c
    

    概要
    

    
    このマルチプロセッシングモジュール (MPM) 
    は、マルチスレッドとマルチプロセスのハイブリッド型サーバを
    実装しています。リクエストの応答にスレッドを使うと、
    プロセスベースのサーバよりも少ないシステム資源で、
    多くのリクエストに応答することができます。
    それにもかかわらず、多くのスレッドを持った複数のプロセスを
    維持することで、
    プロセスベースのサーバの持つ安定性も保持しています。
    

    
    この MPM を制御するのに使われる最も重要なディレクティブは、
    ThreadsPerChild と
    MaxClients です。
    ThreadsPerChild は
    各子プロセスで用意されるスレッド数を制御して、
    MaxClients は
    起動されるスレッドの総数の最大値を制限します。
    

    


    top
    

    

    動作方法
    
    
    一つの制御用プロセス (親) が子プロセスを起動します。
    子プロセスは
    ThreadsPerChild
    ディレクティブで指定された一定数のサーバスレッドと接続を
    listen するスレッドを一つ作ります。
    Listener スレッドは接続が来たときにサーバプロセスに渡します。
    

    
    Apache はスペアの、つまりアイドルなサーバスレッドの
    プールを常に維持していて、それらは入ってくるリクエストに
    答えられるように待機しています。
    このようにして、クライアントはリクエストの応答が得られるようになるために
    新しいスレッドやプロセスが生成されるのを
    待たなくてもよいようになっています。
    起動初期時のプロセス総数は、
    StartServers
    ディレクティブで設定されます。稼働中に、
    Apache は全プロセスのアイドルスレッドの合計数を見積もって、
    MinSpareThreads と
    MaxSpareThreads
    で指定された範囲の中にこの数が収まるように fork したり
    kill したりします。この操作は非常に自律的なので、
    これらのディレクティブをデフォルト値から変更する必要は
    めったにないでしょう。
    同時に応答することのできるクライアント数の最大数
    (つまり全プロセス中の総スレッド数の最大値) は
    MaxClients
    ディレクティブで決定されます。
    活動中の子プロセス数の最大値は
    MaxClients を
    ThreadsPerChild で割った
    ものになります。
    
    
    
    活動中の子プロセスの数と子プロセス中のサーバスレッドの数の越えられない
    上限を設定するディレクティブが二つあります。これらはサーバを
    完全に停止して、再起動することでしか変更することはできません。
    ServerLimit
     は活動中の子プロセスの越えられない上限を設定し、
    MaxClients ディレクティブ
    の値を 
    ThreadsPerChild の値で割った値以上である
    必要があります。ThreadLimit は
    サーバスレッドの越えられない上限で、ThreadsPerChild ディレクティブの
    値以上である必要があります。
    

    
    活動中の子プロセス群に加えて、少なくとも一つのサーバスレッドが
    既存のクライアントからの接続を扱っている終了しようとしている
    子プロセスがある可能性があります。終了中のプロセスは MaxClients で指定された数まで
    存在できますが、実際に期待される数はずっと少なくなります。この
    振舞いは各子プロセスを終了させないようにすることで回避できます。
    これは以下の様にして実現できます。
    
     
    

    
    worker MPM の典型的なプロセス・スレッド制御の
    設定では、次のようになります。
    

    
    
      ServerLimit         16
    
      StartServers         2
    
      MaxClients         150
    
      MinSpareThreads     25
    
      MaxSpareThreads     75
    
      ThreadsPerChild     25
    
    

    
    通常 Unix では親プロセスは 80 番ポートにバインドするために
    root で起動されますが、子プロセスやスレッドは
    もっと低い権限のユーザで Apache によって起動されます。
    User と
    Group ディレクティブは
    Apache の子プロセスの権限を設定するのに用いられます。
    子プロセスはクライアントに送るコンテンツ全てを読めないといけませんが、
    可能な限り必要最小限の権限のみを持っているようにするべきです。
    さらに、suexec
    が使用されていない限り、これらのディレクティブは
    CGI スクリプトで継承される権限も設定します。
    

    
    MaxRequestsPerChild
    は、古いプロセスを停止して新しいプロセスを起動することによって、
    どの程度の頻度でサーバがプロセスをリサイクルするかを制御します。

    Module Identifier:env_module
    

    Source File:mod_env.c
    

    Summary
    

    
    This module allows for control of internal environment variables that
    are used by various Apache HTTP Server modules. These variables are also
    provided to CGI scripts as native system environment variables, and available
    for use in SSI pages. Environment variables may be passed from the shell
    which invoked the httpd process. Alternatively,
    environment variables may be set or unset within the configuration process.

    Description:Passes environment variables from the shell
    

    Syntax:PassEnv env-variable [env-variable]

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_env
    

    
    
    Specifies one or more native system environment variables to make available
    as internal environment variables, which are available to Apache HTTP Server modules
    as well as propagated to CGI scripts and SSI pages. Values come from the
    native OS environment of the shell which invoked the
    httpd process.
    

    
    Example
    PassEnv LD_LIBRARY_PATH

    SetEnv Directive
    

    

    Description:Sets environment variables
    

    Syntax:SetEnv env-variable [value]
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_env
    

    
    
    Sets an internal environment variable, which is then available to Apache
    HTTP Server modules, and passed on to CGI scripts and SSI pages.
    

    
    Example
    SetEnv SPECIAL_PATH /foo/bin
    

    
 
    
     If you omit the value argument, the variable is set to
    an empty string.
    

    
    The internal environment variables set by this directive are set
    after most early request processing directives are run, such as access
    control and URI-to-filename mapping.  If the environment variable you're
    setting is meant as input into this early phase of processing such as the
    RewriteRule directive, you should
    instead set the environment variable with
    SetEnvIf.

    Apache Module mod_proxy_http
    

    

    Available Languages:  en  |

    Description:HTTP support module for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_http_module
    

    Source File:mod_proxy_http.c
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides the features used for
    proxying HTTP and HTTPS requests. mod_proxy_http
    supports HTTP/0.9, HTTP/1.0 and HTTP/1.1. It does not
    provide any caching abilities. If you want to set up a caching
    proxy, you might want to use the additional service of the
    mod_cache module.
    

    
    Thus, in order to get the ability of handling HTTP proxy requests,
    mod_proxy and mod_proxy_http
    have to be present in the server.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.
    
    
    

    

    Support Apache!

    Environment Variables
    
    
    In addition to the configuration directives that control the
    behaviour of mod_proxy, there are a number of
    environment variables that control the HTTP protocol
    provider. Environment variables below that don't specify specific values
    are enabled when set to any value.
    
    
    
        
    proxy-sendextracrlf
    
        
    Causes proxy to send an extra CR-LF newline on the end of a
        request.  This is a workaround for a bug in some browsers.
    
        
    force-proxy-request-1.0
    
        
    Forces the proxy to send requests to the backend as HTTP/1.0
        and disables HTTP/1.1 features.
    
        
    proxy-nokeepalive
    
        
    Forces the proxy to close the backend connection after
        each request.
    
        
    proxy-chain-auth
    
        
    If the proxy requires authentication, it will read and
        consume the proxy authentication credentials sent by the client.
        With proxy-chain-auth it will also forward
        the credentials to the next proxy in the chain.  This may
        be necessary if you have a chain of proxies that share
        authentication information.  Security Warning:
        Do not set this unless you know you need it, as it forwards
        sensitive information!
    
        
    proxy-sendcl
    
        
    HTTP/1.0 required all HTTP requests that include a body
        (e.g. POST requests) to include a Content-Length
        header.  This environment variable forces the Apache proxy to
        send this header to the backend server, regardless of what the
        Client sent to the proxy.  It ensures compatibility when
        proxying for an HTTP/1.0 or unknown backend.  However, it
        may require the entire request to be buffered by the proxy,
        so it becomes very inefficient for large requests.
    
        
    proxy-sendchunks or proxy-sendchunked
    
        
    This is the opposite of proxy-sendcl.  It allows
        request bodies to be sent to the backend using chunked transfer
        encoding.  This allows the request to be efficiently streamed,
        but requires that the backend server supports HTTP/1.1.
    
        
    proxy-interim-response
    
        
    This variable takes values RFC (the default) or
        Suppress.  Earlier httpd versions would suppress
        HTTP interim (1xx) responses sent from the backend.  This is
        technically a violation of the HTTP protocol.  In practice,
        if a backend sends an interim response, it may itself be
        extending the protocol in a manner we know nothing about,
        or just broken.  So this is now configurable: set
        proxy-interim-response RFC to be fully protocol
        compliant, or proxy-interim-response Suppress
        to suppress interim responses.
    
        
    proxy-initial-not-pooled
    
        
    If this variable is set, no pooled connection will be reused
        if the client request is the initial request on the frontend connection. This avoids
        the "proxy: error reading status line from remote server" error message
        caused by the race condition that the backend server closed the
        pooled connection after the connection check by the proxy and
        before data sent by the proxy reached the backend. It has to be
        kept in mind that setting this variable downgrades performance,
        especially with HTTP/1.0 clients.

    Request notes
    
    
    mod_proxy_http creates the following request notes for
        logging using the %{VARNAME}n format in
        LogFormat or
        ErrorLogFormat:
    
    
    
    
        
    proxy-source-port
    
        
    The local port used for the connection to the backend server.
    
        
    proxy-status
    
        
    The HTTP status received from the backend server.

    Module Apache mod_privileges

    Description:Support des privilèges de Solaris et de l'exécution des
serveurs virtuels sous différents identifiants
utilisateurs.
    

    Statut:Expérimental
    

    Identificateur de Module:privileges_module
    

    Fichier Source:mod_privileges.c
    

    Compatibilité:Disponible depuis la version 2.3 d'Apache sur les
plates-formes Solaris 10 et OpenSolaris
    

    Sommaire
    


    Ce module permet l'exécution de différents serveurs virtuels sous
différents identifiants Unix User et Group,
et avec différents Privilèges
Solaris. En particulier, il apporte au problème de
séparation des privilèges entre les différents serveurs virtuels la
solution que devait apporter le module MPM abandonné perchild. Il
apporte aussi d'autres améliorations en matière de sécurité.
    


    À la différence de perchild, mod_privileges n'est
pas un module MPM. Il travaille au sein d'un modèle de
traitement pour définir les privilèges et les User/Group pour chaque
requête dans un même processus. Il n'est donc pas compatible avec
les MPM threadés, et refusera de s'exécuter en cas d'utilisation d'un de
ces derniers.
    


    mod_privileges traite des problèmes de sécurité
similaires à ceux de suexec ; mais à la
différence de ce dernier, il ne s'applique pas seulement aux programmes
CGI, mais à l'ensemble du cycle de traitement d'une requête, y compris
les applications in-process et les sous-processus. Il convient
particulièrement à l'exécution des applications PHP sous
mod_php, qui est lui-même incompatible avec les modules
MPM threadés. Il est également bien adapté aux autres applications de type
script in-process comme mod_perl,
mod_python, et mod_ruby, ainsi qu'aux
applications en langage C telles que les modules Apache pour lesquels la
séparation des privilèges constitue un problème.
    


    


    top
    

    

    Considérations à propos de sécurité
    


    mod_privileges introduit de nouveaux problèmes de
sécurité dans les situations où du code non sûr peut
s'exécuter à l'intérieur du processus du serveur web.
Ceci s'applique aux modules non sûrs, et aux scripts s'exécutant sous
des modules comme mod_php ou mod_perl. Les scripts s'exécutant en
externe (comme par exemple les scripts CGI ou ceux s'exécutant sur un
serveur d'applications derrière mod_proxy ou mod_jk) ne sont pas
concernés.
    


    Les principaux problèmes de sécurité que l'on rencontre avec
mod_privileges sont :
    



    • L'exécution sous un utilisateur système pose les mêmes problèmes
de sécurité que mod_suexec, et pratiquement les mêmes que cgiwrap et
suphp.
      • 

    • Une extension utilisateur (module ou script) malveillante, écrite en connaissant les mécanismes
utilisés par mod_privileges,
pourrait élever ses privilèges à tout niveau
accessible au processus httpd dans tout serveur virtuel. Ceci introduit
de nouveaux risques si (et seulement si) mod_privileges est compilé avec
l'option BIG_SECURITY_HOLE.
      • 

    • Une extension utilisateur (module ou script) malveillante, écrite en connaissant les mécanismes
utilisés par mod_privileges,
pourrait élever ses privilèges pour s'attribuer
l'identifiant utilisateur d'un autre utilisateur (et/ou groupe)
système.
      • 

    


    La directive PrivilegesMode vous permet de
sélectionner soit le mode FAST, soit le mode
SECURE. Vous pouvez panacher les modes en utilisant par
exemple le mode FAST pour les utilisateurs de confiance et
les chemins contenant du code entièrement audité, tout en imposant le
mode SECURE où un utilisateur non sûr a la possibilité
d'introduire du code.
    

    Avant de décrire les modes, il nous faut présenter les cas
d'utilisation de la cible : "Benign" ou "Hostile". Dans une situation
"Benign", vous voulez séparer les utilisateurs pour leur confort, et les
protéger, ainsi que le serveur, contre les risques induits par les
erreurs involontaires. Dans une situation "Hostile" - par exemple
l'hébergement d'un site commercial - il se peut que des utilisateurs
attaquent délibérément le serveur ou s'attaquent entre eux.
    

    

    Mode FAST
    

    En mode FAST, les requêtes sont traitées "in-process"
avec les uid/gid et privilèges sélectionnés, si bien que la
surcharge est négligeable. Ceci convient aux situations "Benign", mais
n'est pas sécurisé contre un attaquant augmentant ses privilèges avec un
module ou script "in-process".
    

    Mode SECURE
    

    Une requête en mode SECURE génère un sous-processus qui
supprime les privilèges. Ce comportement est très similaire à
l'exécution d'un programme CGI avec suexec, mais il reste valable tout
au long du cycle de traitement de la requête, avec en plus l'avantage
d'un contrôle précis des privilèges.
    

    

    Vous pouvez sélectionner différents
PrivilegesModes pour chaque serveur virtuel, et
même dans un contexte de répertoire à l'intérieur d'un serveur virtuel.
Le mode FAST convient lorsque les utilisateurs sont sûrs
et/ou n'ont pas le privilège de charger du code "in-process". Le mode
SECURE convient dans les cas où du code non sûr peut
s'exécuter "in-process".  Cependant, même en mode SECURE, il
n'y a pas de protection contre un utilisateur malveillant qui a la
possibilité d'introduire du code supportant les privilèges avant le
début du cycle de traitement de la requête.

    pas à elle-seule DTrace, mais que DTracePrivileges Off
    l'empêchera de fonctionner.

    Directive PrivilegesMode
    

    

    Description:Fait un compromis entre d'une part l'efficacité et la
vitesse de traitement et d'autre part la sécurité à l'encontre des codes
malicieux supportant les privilèges.
    

    Syntaxe:PrivilegesMode FAST|SECURE|SELECTIVE
    

    Défaut:PrivilegesMode FAST
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Expérimental
    

    Module:mod_privileges
    

    Compatibilité:Disponible sous Solaris 10 et OpenSolaris avec des
modules MPMs non threadés (comme prefork ou un module
personnalisé).
    

    Cette directive permet de faire un compromis entre les
performances et la sécurité à l'encontre des codes malicieux supportant
les privilèges. En mode SECURE, chaque requête est traitée
dans un sous-processus sécurisé, ce qui induit une dégradation sensible
des performances. En mode FAST, le serveur n'est pas protégé
contre l'augmentation de privilège comme décrit plus haut.
    

    Cette directive est sensiblement différente selon qu'elle se trouve
dans une section <Directory> (ou Location/Files/If)
ou au niveau global ou dans un <VirtualHost>.
    

    Au niveau global, elle définit un comportement par défaut dont
hériteront les serveurs virtuels. Dans un serveur virtuel, les modes
FAST ou SECURE agissent sur l'ensemble de la requête HTTP, et toute
définition de ces modes dans une section <Directory>
sera ignorée. Le pseudo-mode SELECTIVE confie le choix
du mode FAST ou SECURE aux directives contenues dans une
section<Directory>.
    

    Dans une section <Directory>, elle ne s'applique
que lorsque le mode SELECTIVE a été défini pour le serveur virtuel.
Seuls FAST ou SECURE peuvent être définis dans ce contexte (SELECTIVE
n'aurait pas de sens).
    

    Avertissement
    
	Lorsque le mode SELECTIVE a été défini pour un serveur virtuel,
	l'activation des privilèges doit être reportée après
	la détermination, par la phase de comparaison du traitement de
	la requête, du contexte <Directory> qui
	s'applique à la requête. Ceci peut donner à un attaquant
	l'opportunité d'introduire du code via une directive RewriteMap s'exécutant au
	niveau global ou d'un serveur virtuel avant que les
	privilèges n'aient été supprimés et l'uid/gid défini.

    Détermine si le serveur virtuel est autorisé à exécuter fork et
    exec, et définit les privilèges requis pour exécuter des sous-processus. Si cette
    directive est définie à Off le serveur virtuel ne
    disposera d'aucun privilège et ne pourra exécuter ni des programmes
    ou scripts CGI classiques via le module traditionnel
    mod_cgi, ni des programmes externes similaires tels
    que ceux créés via le module mod_ext_filter ou les
    programmes de réécriture externes utilisés par la directive
    RewriteMap. Notez que
    ceci n'empêche pas l'exécution de programmes CGI via d'autres
    processus et sous d'autres modèles de sécurité comme mod_fcgid, ce qui est la
    solution recommandée sous Solaris.
    
    
    Si cette directive est définie à On ou
    Secure, le serveur virtuel pourra exécuter les scripts et
    programmes externes cités ci-dessus. Définir la directive
    VHostCGIMode à Secure a pour effet
    supplémentaire de n'accorder aucun privilège aux sous-processus,
    comme décrit dans la directive
    VHostSecure.

    La directive VHostCGIPrivs permet
    d'assigner des privilèges au choix aux sous-processus créés par un serveur
    virtuel, comme décrit dans la directive
    VHostCGIMode. Chaque
    privilege-name correspond à un privilège Solaris tel que
    file_setid ou sys_nfs.
    

    
    privilege-name peut être éventuellement préfixé par +
    ou -, ce qui va respectivement accorder ou refuser le privilège. Si
    nom-privilège est spécifié sans + ni -, tous les autres
    privilèges préalablement assignés au serveur virtuel seront refusés.
    Cette directive permet de construire aisément votre propre jeu de

    Module Apache mod_macro
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Ce module permet d'utiliser des macros dans les fichiers
de configuration Apache.
    

    Statut:Base
    

    Identificateur de Module:macro_module
    

    Fichier Source:mod_macro.c
    

    Compatibilité:Disponible à partir de la version 2.4.5 du serveur HTTP Apache
    

    Sommaire
    


    
    Ce module permet d'utiliser des macros dans les fichiers de
    configuration à l'exécution du serveur HTTP Apache afin de faciliter
    la création de nombreux blocs de configuration similaires. Quand le
    serveur démarre, les macros sont exécutées avec les paramètres
    fournis, et le résultat obtenu est traité au même titre que le reste
    du fichier de configuration.
    


    


    top
    

    

    Utilisation
        

    On définit une macro à l'aide des blocs <Macro> qui contiennent la portion de votre
configuration qui intervient de manière répétitive, y compris les
variables pour les parties qui devront être substituées.
    


    Par exemple, vous pouvez utiliser une macro pour définir un bloc
<VirtualHost>, afin de pouvoir
définir de nombreux serveurs virtuels similaires :
        

    
    <Macro VHost $name $domain>
<VirtualHost *:80>
    ServerName $domain
    ServerAlias www.$domain

    DocumentRoot "/var/www/vhosts/$name"
    ErrorLog "/var/log/httpd/$name.error_log"
    CustomLog "/var/log/httpd/$name.access_log" combined
</VirtualHost>
</Macro>
    



    Comme les directives de configuration httpd, les noms des macros sont
insensibles à la casse, à la différence des variables qui y sont, elles,
sensibles.
    


    Vous pouvez alors invoquer cette macro autant de fois que vous le
voulez pour créer des serveurs virtuels 
    


    Use VHost example example.com
Use VHost myhost hostname.org
Use VHost apache apache.org

UndefMacro VHost
    



    Au démarrage du serveur, chacune de ces invocations
Use sera remplacée par une définition de serveur
virtuel complète, comme décrit dans la définition de la
<Macro>.
    


    La directive UndefMacro permet d'éviter les
conflits de définitions qui pourraient provenir de l'utilisation
ultérieure de macros contenant les mêmes noms de variables.
    


    Vous trouverez une version plus élaborée de cet exemple plus loin
dans la section Exemples.
    


    top
    

    

    Conseils
    


    Les noms de paramètres doivent commencer par un sigil tel que
$, %, ou @, de façon à ce qu'ils
soient clairement identifiables, mais aussi afin de faciliter les
interactions avec les autres directives, comme la directive de base
Define. Dans le cas contraire, vous
recevrez un avertissement. En tout état de cause, il est conseillé
d'avoir une bonne connaissance globale de la configuration du serveur,
afin d'éviter la réutilisation des mêmes variables à différents niveaux,
ce qui peut être à l'origine de confusions.
    


    Les paramètres préfixés par $ ou % ne sont
pas échappés. Les paramètres préfixés par @ sont échappés
entre guillemets.
    


    Evitez de préfixer un paramètre par le nom d'un autre paramètre (par
exemple, présence simultanée des paramètres $win et
$winter), car ceci peut introduire de la confusion lors de
l'évaluation des expressions. Si cela se produit, c'est le nom de
paramètre le plus long possible qui sera utilisé.
    


    Si vous désirez insérer une valeur dans une chaîne, il est conseillé
de l'entourer d'accolades afin d'éviter toute confusion :
    


    <Macro DocRoot ${docroot}>
    DocumentRoot "/var/www/${docroot}/htdocs"
</Macro>
    



    top
    

    

    Exemples
    



    Définition de serveurs virtuels
    



    Un exemple typique d'utilisation de mod_macro est la
création dynamique de serveurs virtuels.
    


    ## Définition d'une macro VHost pour les configurations répétitives

<Macro VHost $host $port $dir>
  Listen $port
  <VirtualHost *:$port>

    ServerName $host
    DocumentRoot "$dir"

    # Racine des documents publique
    <Directory "$dir">
      Require all granted
    </Directory>

    # restriction d'accès au sous-répertoire intranet.
    <Directory "$dir/intranet">
      Require ip 10.0.0.0/8
    </Directory>
  </VirtualHost>
</Macro>

## Utilisation de la macro VHost avec différents arguments.

Use VHost www.apache.org 80 /vhosts/apache/htdocs
Use VHost example.org 8080 /vhosts/example/htdocs
Use VHost www.example.fr 1234 /vhosts/example.fr/htdocs
    

 


    Suppression d'une définition de macro
    



    Il est recommandé de supprimer la définition d'une macro après
l'avoir utilisée. Ceci permet d'éviter les confusions au sein d'un
fichier de configuration complexe où des conflits entre noms de
variables peuvent survenir.
    


    <Macro DirGroup $dir $group>
  <Directory "$dir">
    Require group $group
  </Directory>
</Macro>

Use DirGroup /www/apache/private private
Use DirGroup /www/apache/server  admin

    Sommaire
    


    
    Ce module permet d'enregistrer le nombre d'octets reçus et
    envoyés pour chaque requête. Ce nombre reflète le nombre réel
    d'octets transmis sur le réseau, et prend en compte les en-têtes et
    corps des requêtes et des réponses. Le décompte est effectué avant
    SSL/TLS en entrée et après SSL/TLS en sortie, si bien que le
    résultat reflètera toute modification introduite par le
    chiffrement.
    

    
    Pour fonctionner, ce module requiert le chargement du module
    mod_log_config.
    

    
    Lorsqu'on utilise les connexions persistantes avec SSL, le
    supplément de trafic induit par la négociation SSL est enregistré
    dans le décompte des octets transmis dans le cadre de la première
    requête de la connexion. Lors d'une renégociation SSL au niveau d'un
    répertoire, le décompte d'octets est associé à la
    requête qui a déclenché la renégociation.

    Formats de journaux personnalisés
    


    
    Ce module introduit trois nouvelles directives de journalisation.
    Les caractéristiques de la requête en elle-même sont journalisées en
    insérant des directives "%" dans la chaîne de format,
    qui seront remplacées comme suit dans le fichier journal :
    

    
    Chaîne de Format
        Description
    

    %I
        Octets reçus, en-têtes et corps de requête inclus ; ne peut

    Description:Fonctionnalité de création et gestion de versions de
documents via le web (WebDAV)
    

    Statut:Extension
    

    Identificateur de Module:dav_module
    

    Fichier Source:mod_dav.c
    

    Sommaire
    

    
    Ce module ajoute à Apache une fonctionnalité WebDAV de classes 1 et 2
    ('Web-based Distributed Authoring and Versioning' ou Création et
    gestion de versions de documents via le web). Il s'agit d'une
    extension du protocole HTTP qui permet de créer, déplacer, copier et
    supprimer des ressources ou collections de ressources sur un serveur
    web distant.
    

    


    top
    

    

    Activation de WebDAV
    
    
    Pour activer le module mod_dav, ajoutez la ligne
    suivante à un conteneur de votre fichier httpd.conf
    :
    

    
    Dav On
    


    
    Ceci active le fournisseur de système de fichier DAV implémenté par
    le module mod_dav_fs. Ce dernier doit donc être
    compilé dans le serveur ou chargé au démarrage à l'aide de la
    directive LoadModule.
    

    
    En outre, vous devez indiquer où se trouve la base de données des
    verrous DAV via une directive DavLockDB dans la section globale de
    votre fichier httpd.conf :
    

    
    DavLockDB /usr/local/apache2/var/DavLock
    


    
    Le répertoire contenant le fichier de la base de données des
    verrous doit avoir des droits en écriture pour l'utilisateur et le
    groupe sous lesquels Apache s'exécute et définis respectivement par
    les directives User et
    Group.
    

    
    Si vous souhaitez limiter l'accès aux répertoires où DAV est
    activé, vous pouvez ajouter une clause <Limit> dans la section <Location> considérée. Pour
    définir la quantité maximale de données en octets qu'un client
    DAV peut envoyer par requête, vous devez utiliser la directive
    LimitXMLRequestBody, car La
    directive LimitRequestBody
    "habituelle" n'a aucune incidence sur les requêtes DAV.
    

    
    Exemple complet
    DavLockDB "/usr/local/apache2/var/DavLock"

<Directory "/usr/local/apache2/htdocs/foo">
    Require all granted
    Dav On

    AuthType Basic
    AuthName DAV
    AuthUserFile "user.passwd"

    <LimitExcept GET POST OPTIONS>
        Require user admin
    </LimitExcept>
</Directory>
    

    


    top
    

    

    Problèmes concernant la sécurité
    

    
    Etant donné que les méthodes d'accès DAV permettent à des clients
    distants de manipuler des fichiers sur le serveur, vous devez vous
    assurer que votre serveur est bien sécurisé avant d'activer
    mod_dav.
    

    
    Tout répertoire du serveur où DAV est activé doit être protégé
    par une procédure d'authentification. L'utilisation de
    l'authentification HTTP de base n'est pas recommandée. Vous devez
    utiliser au moins l'authentification HTTP à base de condensés
    qu'implémente le module mod_auth_digest.
    Pratiquement tous les clients WebDAV supportent cette méthode
    d'authentification. Vous pouvez aussi utiliser l'authentification de
    base sur une connexion où SSL est activé.
    

    
    Pour que mod_dav puisse manipuler des fichiers,
    il doit avoir des permissions en écriture sur les répertoires et les
    fichiers qui sont sous son contrôle ; en d'autre termes, c'est
    l'utilisateur et le groupe sous lesquels Apache s'exécute et définis
    par les directives User et
    Group qui doivent avoir
    les droits en écriture sur ces fichiers et répertoires. Les fichiers
    nouvellement créés appartiendront aussi à ces utilisateur et groupe.
    Par conséquent, il est important de contrôler l'accès à ce compte.
    Les répertoires DAV sont considérés comme privés du point de vue
    d'Apache, et la modification des fichiers qu'ils contiennent
    autrement que par l'intermédiaire d'Apache (par exemple par FTP ou
    par des outils du niveau du système de fichiers) ne doit pas être
    permise.
    

    
    mod_dav peut faire l'objet de plusieurs sortes
    d'attaques par déni de service. La directive LimitXMLRequestBody permet de limiter la
    quantité de mémoire consommée pour interpréter des requêtes DAV de
    grande taille. En outre, la directive DavDepthInfinity permet d'empêcher les
    requêtes PROPFIND concernant un répertoire de très
    grande taille de consommer de grandes quantités de mémoire. Un autre
    type d'attaque par déni de service peut aussi être mené par un
    client qui remplit simplement tout l'espace disque disponible avec
    des fichiers de très grande taille. Etant donné qu'il n'existe aucun
    moyen direct d'éviter ce genre d'attaque dans Apache, vous ne devez
    accorder des accès DAV qu'à des utilisateurs de confiance.
    

    top
    

    

    Configurations complexes
    

    
    Les requêtes ayant pour but de manipuler des fichiers dynamiques
    (scripts PHP, scripts CGI, etc...) en utilisant
    mod_dav sont courantes. Ce traitement n'est pas
    évident car une requête
    GET va toujours tenter d'exécuter le script, plutôt que
    de télécharger son contenu. Pour éviter cet inconvénient, une
    méthode possible consiste à faire correspondre deux URLs
    différentes au même contenu, l'une d'entre elles servant à lancer le
    script, alors que l'autre peut être utilisée pour le télécharger et
    le manipuler avec DAV.
    


    Alias "/phparea" "/home/gstein/php_files"
Alias "/php-source" "/home/gstein/php_files"
<Location "/php-source">
Dav On
ForceType text/plain
</Location>
    


    
    Avec cette configuration, on peut utiliser
    http://example.com/phparea pour afficher le résultat de
    l'exécution des scripts PHP, et
    http://example.com/php-source pour les manipuler avec
    DAV.

    Directive Dav
    

    

    Description:Active les méthodes HTTP WebDAV
    

    Syntaxe:Dav On|Off|nom fournisseur
    

    Défaut:Dav Off
    

    Contexte:répertoire
    

    Statut:Extension
    

    Module:mod_dav
    

    
    
    La directive Dav permet d'activer les
    méthodes HTTP WebDAV pour le conteneur condidéré :
    

    
    <Location "/foo">
    Dav On
</Location>
    


    
    La valeur On est en fait un alias vers le
    fournisseur par défaut filesystem implémenté par le
    module mod_dav_fs. Notez que lorsque DAV est activé
    pour un conteneur, on ne peut pas le désactiver pour ses
    sous-conteneurs. Pour un exemple de configuration complet,
    reportez-vous à la section précédente.
    

    
    
      N'activez pas WebDAV tant que votre serveur n'est pas sécurisé. Si
      vous passez outre cette recommandation, tout le monde pourra
      enregistrer des fichiers sur votre système.

    La directive DavDepthInfinity permet
    d'autoriser le traitement des requêtes PROPFIND
    contenant l'en-tête Depth: Infinity. Par défaut, ce type de requête
    n'est pas autorisé, car il peut favoriser les attaques de type Déni
    de service.

    Directive DavMinTimeout
    

    

    Description:Durée minimale pendant laquelle le serveur maintient un
verrou sur une ressource DAV
    

    Syntaxe:DavMinTimeout secondes
    

    Défaut:DavMinTimeout 0
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Extension
    

    Module:mod_dav
    

    
    
    Lorsqu'un client demande le verrouillage d'une ressource DAV, il
    peut aussi spécifier une durée au bout de laquelle le verrou sera
    automatiquement supprimé par le serveur. Cette valeur ne constitue
    qu'une demande, et le serveur peut l'ignorer ou informer le client
    qu'il va utiliser une valeur arbitraire.
    

    
    La directive DavMinTimeout permet de
    spécifier, en secondes, la durée minimale de verrouillage à renvoyer
    au client. Les Répertoires Web de Microsoft présentent une durée par
    défaut de 120 secondes ; la directive
    DavMinTimeout permet de définir une valeur
    supérieure (par exemple 600 secondes), afin de réduire les risques
    de perte du verrou par le client suite à une surcharge du
    réseau.
    

    
    Exemple
    <Location "/MSWord">
    DavMinTimeout 600
</Location>

    Description:Une série de directives implémentées par plusieurs
modules multi-processus (MPM)
    

    Statut:MPM
    

    



    top
    

    Directive CoreDumpDirectory
    

    

    Description:Le répertoire dans lequel le serveur HTTP Apache va tenter de se
positionner avant d'effectuer un vidage mémoire
    

    Syntaxe:CoreDumpDirectory répertoire
    

    Défaut:Voir ci-dessous pour le répertoire par défaut
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:event, worker, prefork
    

    
    
    Cette directive permet de définir le répertoire dans lequel
    Apache httpd va tenter de se positionner avant d'effectuer un vidage
    mémoire sur disque.
    Si votre système d'exploitation est configuré pour créer des
    fichiers de vidage mémoire dans le répertoire de travail des
    processus qui se sont crashés,
    CoreDumpDirectory est nécessaire pour
    définir un répertoire de travail autre que le répertoire par défaut
    ServerRoot, ce répertoire de
    travail ne devant pas être accessible en écriture par l'utilisateur sous
    lequel le serveur s'exécute.
    

    
    Si vous avez besoin d'un vidage mémoire pour le débogage, vous
    pouvez utiliser cette directive pour le placer à un endroit
    différent. Cette directive n'a aucun effet si votre système
    d'exploitation n'est pas configuré pour créer des
    fichiers de vidage mémoire dans le répertoire de travail des
    processus qui se sont crashés.
    

    
    
      
    Note de sécurité pour les systèmes de type Linux
    

      
    Utiliser cette directive sous Linux peut permettre aux autres processus
      du système s'exécutant avec les même privilèges (comme les scripts CGI) de
      se rattacher aux processus httpd enfants via l'appel système
      ptrace. La protection contre certaines attaques engageant la
      sécurité peut s'en trouver affectée. Il est par conséquent déconseillé
      d'utiliser cette directive sur les systèmes en production.
    
    
    

    
    Vidages mémoire sous Linux
    
      
    Si Apache httpd est démarré sous l'utilisateur root puis bascule vers
      un autre utilisateur, le noyau Linux désactive les
      vidages mémoire, même si le répertoire est accessible en écriture au
      processus. Apache httpd (versions 2.0.46 et supérieures) réactive les
      vidages mémoire sous Linux 2.4 et au delà, mais seulement si vous
      définissez une directive CoreDumpDirectory.
    
    
    

    
    
    
    Vidages mémoire sous BSD
    
    
    Pour activer le vidage mémoire des exécutables suid sur les
    systèmes de style BSD (comme FreeBSD), définissez
    kern.sugid_coredump à 1.
    
    
    
    

    
    Signaux spécifiques
    
      
    CoreDumpDirectory n'est traité qu'à la
      reception d'un certain nombre de signaux , SIGFPE, SIGILL, SIGABORT,
      SIGSEGV, et SIGBUS.
    
      
    
      Sur certains systèmes d'exploitation, SIGQUIT provoque aussi un
      vidage mémoire, mais n'est pas traité par les directives
      CoreDumpDirectory ou
      EnableExceptionHook, si bien que la
      définition du répertoire d'enregistrement du vidage mémoire est
      entièrement dévolue au système d'exploitation.

    Directive EnableExceptionHook
    

    

    Description:Active un hook ("point d'accrochage logiciel") qui exécute des
gestionnaires d'exception après un crash
    

    Syntaxe:EnableExceptionHook On|Off
    

    Défaut:EnableExceptionHook Off
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:event, worker, prefork
    

    
    
    Pour des raisons de sécurité, cette directive n'est disponible
    que si la compilation du serveur a été configurée avec l'option
    --enable-exception-hook. Elle permet d'activer un hook
    ("point d'accrochage logiciel")
    qui autorise certains modules externes à effectuer un branchement et
    accomplir telle ou telle action après le crash d'un processus
    enfant.
    

    
    Deux modules, mod_whatkilledus et
    mod_backtrace utilisent ce hook. Veuillez vous
    référer à la page EnableExceptionHook de Jeff Trawick pour plus
    d'informations à leur sujet.

    Directive GracefulShutdownTimeout
    

    

    Description:Spécifie le délai maximum après lequel le serveur va
s'arrêter dans le cas d'un arrêt "en douceur"
    

    Syntaxe:GracefulShutdownTimeout seconds
    

    Défaut:GracefulShutdownTimeout 0
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:event, worker, prefork
    

    Compatibilité:Disponible dans les versions 2.2 et supérieures
    

    
    
    La directive GracefulShutdownTimeout
    permet de spécifier le temps, en secondes, pendant lequel le serveur
    va continuer à fonctionner après avoir reçu un signal
    "graceful-stop" ("Arrêt en douceur"), afin de terminer le traitement
    des connexions en cours.
    

    
    Définir cette valeur à zéro signifie au serveur d'attendre
    jusqu'à ce que toutes les requêtes en cours aient été traitées.
    


    

    top
    

    Directive Listen
    

    

    Description:Les adresses IP et ports sur lesquels le serveur écoute
    

    Syntaxe:Listen [adresse IP:]numéro port
[protocole]
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    Compatibilité:L'argument protocole est supporté depuis la version
2.1.5
    

    
    
    La directive Listen permet de signifier à
    Apache httpd de ne se mettre à l'écoute que sur les adresses IP et ports spécifiés ; par
    défaut, le serveur répond aux requêtes en provenance de toutes les
    interfaces réseau. La directive Listen est
    dorénavant requise, et si elle est absente du fichier de
    configuration, le serveur refusera de démarrer. Ceci constitue un
    changement par rapport aux versions précédentes d'Apache httpd.
    

    
    La directive Listen signifie au serveur de
    n'accepter les requêtes entrantes que vers le port ou le couple
    adresse-port spécifié. Si seulement un port est spécifié, le serveur
    se met à l'écoute sur ce port sur toutes les interfaces réseau. Si une adresse IP
    et un port sont spécifiés, le serveur va se mettre à l'écoute sur ce port sur
    l'interface réseau correspondant à l'adresse IP.
    

    
    On peut utiliser autant de directives
    Listen que nécessaire pour spécifier
    plusieurs adresses et/ou ports à écouter. Le serveur répondra aux
    requêtes vers tous les adresses et ports spécifiés.
    

    
    Par exemple, pour que le serveur accepte les connexions sur les
    ports 80 et 8000, utilisez :
    

    
    Listen 80
Listen 8000
    


    
    Pour que le serveur accepte les connexions sur deux interfaces et
    ports particuliers, spécifiez :
    

    
    Listen 192.170.2.1:80
Listen 192.170.2.5:8000
    


    
    Les adressee IPv6 doivent être entourées de crochets, comme dans
    l'exemple suivant :
    

    
    Listen [2001:db8::a00:20ff:fea7:ccea]:80
    


    
    L'argument optionnel protocole n'est pas nécessaire
    dans la plupart des configurations. S'il est absent,
    https est la valeur par défaut pour le port 443 et
    http l'est pour tous les autres ports. L'argument
    protocole sert à déterminer quel module doit traiter une requête, et
    à appliquer des optimisations spécifiques à certains protocoles à
    l'aide de la directive AcceptFilter.
    

    
    La spécification d'un protocole n'est nécessaire que si vous
    utilisez des ports non standards. Par exemple, pour configurer un
    site en https sur le port 8443 :
    

    
    Listen 192.170.2.1:8443 https
    


    
    Condition d'erreur
    
      Plusieurs directives Listen pour les mêmes
      adresse IP/port vont provoquer l'envoi d'un message d'erreur
      Address already in use.

    Directive ListenBackLog
    

    

    Description:Longueur maximale de la liste d'attente des
connexions
    

    Syntaxe:ListenBackLog backlog
    

    Défaut:ListenBackLog 511
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:event, worker, prefork, mpm_winnt, mpm_netware, mpmt_os2
    

    
    
    La longueur maximale de la liste d'attente des connexions. En
    général, aucune modification n'est nécessaire, ni même souhaitable ;
    cependant, sur certains systèmes, il peut être nécessaire
    d'en augmenter la valeur en cas d'attaque TCP SYN flood (envoi en
    masse de requêtes SYN pour saturer le serveur). Voir le paramètre
    backlog de l'appel système listen(2).
    

    
    En fait, l'argument backlog sera souvent limité à une valeur
    inférieure en fonction du système d'exploitation. Notez aussi que de
    nombreux systèmes d'exploitation ne tiennent pas vraiment compte de
    la valeur spécifiée pour l'argument backlog, mais s'en inspirent
    seulement (et choisissent en général une valeur supérieure).

    Directive ListenCoresBucketsRatio
    

    

    Description:Rapport entre le nombre de coeurs de processeur activés et
le nombre de segments d'écoute
    

    Syntaxe:ListenCoresBucketsRatio ratio
    

    Défaut:ListenCoresBucketsRatio 0 (disabled)
    

    Contexte:configuration globale
    

    Statut:MPM
    

    Module:event, worker, prefork
    

    Compatibilité:Disponible à partir de la version 2.4.13 du serveur HTTP
Apache, avec un noyau supportant l'option de socket
SO_REUSEPORT, et distribuant uniformément les nouvelles
connexions aux sockets d'écoute des processus (ou threads) qui
l'utilisent (par exemple Linux versions 3.9 et ultérieures, mais pas
l'implémentation courante de SO_REUSEPORT par les
plateformes de type BSD.
    

    
    
    Vous pouvez utiliser la directive
    ListenCoresBucketsRatio pour spécifier un
    ratio entre le nombre de coeurs de CPU activés et le nombre de
    segments d'écoute (listeners' buckets) souhaités ; le serveur HTTP Apache va
    alors créernum_cpu_cores / ratio segments d'écoute, chacun
    contenant son propre socket d'écoute Listen sur le ou les mêmes ports ; chaque
    processus enfant sera associé à un seul segment d'écoute (avec une
    distribution de type round-robin des segments à la création des processus
    enfants).
    

    
    Définition du terme coeur de CPU activé ("online")
    
    
    Sous Linux et BSD, un coeur de CPU peut être activé ou désactivé si Hotplug
    a été configuré ; la directive
    ListenCoresBucketsRatio doit donc tenir compte de ce
    paramètre pour calculer le nombre de segments d'écoute à créer.
    
    
    

    
    La directive ListenCoresBucketsRatio peut
    améliorer le support de la montée en charge lorsque l'arrivée de
    nouvelles connexions est/devient un goulot d'étranglement. Le test
    de cette fonctionnalité avec des machines possédant un nombre de
    coeurs de CPU important a permit de constater une amélioration des
    performances significative et des temps de réponse plus courts.
    

    
    Pour que cette fonctionnalité soit activée, le nombre de coeurs
    de CPU doit être égal au moins au double du ratio
    spécifié. Si vous spécifiez la valeur recommandée pour
    ratio, à savoir 8, le nombre minimum de
    coeurs de processeurs disponibles sera alors de 16. La valeur
    optimale de ratio permettant d'obtenir des performances maximales
    doit être calculée pour chaque système cible, en testant plusieurs valeurs
    et en observant les résultats.
    

    
    Cette directive influence le calcul des valeurs limites inférieures de
    MinSpareThreads et MaxSpareThreads. En effet, pour accepter les
    connexions de manière optimale, le nombre de processus enfants doit être un
    multiple du nombre de segments d'écoute.
    

    
    
    
    Cas où plusieurs Listeners ou serveurs HTTP
    Apache partagent la même adresse IP et port
    
    
    La définition de l'option SO_REUSEPORT pour les sockets
    d'écoute permet à plusieurs processus (partageant le même EUID,
    par exemple root) de se rattacher à la même adresse IP et port,
    sans obtenir l'erreur de rattachement que le système génère habituellement
    lorsque ce cas se produit.
    
    
    Cela signifie aussi que plusieurs instances d'Apache httpd configurées
    avec le même IP:port et avec une valeur
    ListenCoresBucketsRatio positive pourraient démarrer
    sans erreur, et fonctionner ensuite avec une répartition uniforme des
    connexions entrantes sur ces différentes instances (ce n'est PAS une
    recommandation et ne constitue pas un usage approprié à tous les cas, mais
    juste un avertissement sur le fait qu'un véritable problème de rattachement
    multiple à un IP:port pourrait alors être occulté).
    
    
    Au sein d'une même instance, Apache httpd vérifie la présence de
    directives Listen multiples avec la même adresse IP
    (ou nom d'hôte) et le même port, et refuse de démarrer si c'est le cas, ce
    qui permet d'éviter la création de segments d'écoute dupliqués qui seraient
    du coup inutiles et affecteraient les performances. Cependant, il ne peut
    pas (et n'essaiera pas de le faire) intercepter tous les cas possibles de
    recouvrement (comme un nom d'hôte correspondant à une adresse IP utilisée
    quelque part ailleurs).

    La directive MaxConnectionsPerChild permet de
    définir le nombre maximum de connexions qu'un processus enfant va
    pouvoir traiter au cours de son fonctionnement. Lorsqu'il a traité
    MaxConnectionsPerChild connexions, le processus
    enfant est arrêté. Si MaxConnectionsPerChild est

    de connexions que le processus pourra traiter.
    

    
    Définir MaxConnectionsPerChild à une valeur

    La directive MaxRequestWorkers permet de fixer le
    nombre maximum de requêtes pouvant être traitées simultanément.
    Si la limite MaxRequestWorkers est atteinte, toute
    tentative de connexion sera normalement mise dans une file
    d'attente, et ceci jusqu'à un certain nombre dépendant de la
    directive ListenBacklog.
    Lorsqu'un processus enfant se libèrera suite à la fin du traitement
    d'une requête, la connexion en attente pourra être traitée à son
    tour.
    

    
    Pour les serveurs non threadés (c'est à dire utilisant
    prefork), la directive
    MaxRequestWorkers définit alors le nombre maximum de
    processus enfants qui pourront être lancés simultanément pour
    traiter les requêtes. La valeur par défaut est 256 ; si
    vous l'augmentez, vous devez aussi augmenter la valeur de la
    directive ServerLimit.
    

    
    Pour les serveur threadés et hybrides (utilisant par
    exemple event ou worker),
    MaxRequestWorkers définit alors le nombre total de
    threads qui seront disponibles pour servir les clients. Dans le
    cas des MPMs hybrides, la valeur par défaut est 16
    (directive ServerLimit) multiplié par la valeur
    25 (directive ThreadsPerChild). Par conséquent, pour affecter à la
    directive MaxRequestWorkers une valeur qui requiert
    plus de 16 processus, vous devez aussi augmenter la valeur de la
    directive ServerLimit.
    

    
    Le nom de la directive MaxRequestWorkers
    était MaxClients avant la version 2.3.13. Cet
    ancien nom est encore supporté.

    C'est le nombre maximum de threads inactifs. Les MPMs utilisent
    cette directive de différentes manières.
    

    
    Pour worker et event, la définition par défaut est
    MaxSpareThreads 250. Ce MPM gère les threads inactifs
    au niveau du serveur. Si le serveur possède trop de threads
    inactifs, des processus enfants seront arrêtés jusqu'à ce que le
    nombre de threads inactifs repasse en dessous de cette limite. Des
    processus/threads supplémentaires sont susceptibles d'être créés si
    ListenCoresBucketsRatio est
    activée.
    

    
    Pour mpm_netware, la définition par défaut est
    MaxSpareThreads 100. Comme ce MPM n'exécute qu'un seul
    processus, le nombre de processus inactifs est surveillé au
    niveau du serveur.
    

    
    mpmt_os2 fonctionne de manière similaire à

    Avec worker et event, la définition par défaut est
    MinSpareThreads 75, et le nombre de threads inactifs
    est surveillé au niveau du serveur. Si le serveur ne possède pas
    assez de threads inactifs, des processus enfants sont créés jusqu'à
    ce que le nombre de threads inactifs repasse au dessus de
    nombre. Des processus/threads supplémentaires peuvent
    être créés si ListenCoresBucketsRatio est activée.
    

    
    Avec mpm_netware, la définition par défaut est

    Le serveur HTTP Apache utilise un tableau de bord pour la
    communication entre le processus parent et les processus enfants.
    Pour faciliter cette communication, certaines architectures
    nécessitent un fichier. En l'absence de cette directive, donc si
    aucun nom de fichier n'est spécifié, Apache httpd tentera tout
    d'abord de créer un tableau uniquement en mémoire (en utilisant la
    mémoire partagée anonyme) ; et si il n'y parvient pas, il tentera de
    créer un fichier sur disque (en utilisant la mémoire partagée à base
    de fichier). Si cette directive est utilisée, Apache httpd créera
    systématiquement un fichier sur disque.
    

    
    Exemple
    ScoreBoardFile /var/run/apache_runtime_status
    

    

    
    Une mémoire partagée sous forme de fichier est utile pour les
    applications tierces qui nécessitent un accès direct au tableau de
    bord des processus.
    

    
    Si vous utilisez un ScoreBoardFile, vous
    pourrez constater une amélioration des performances en le plaçant
    sur un disque virtuel en RAM. Assurez-vous cependant de tenir compte
    des mêmes avertissements que ceux concernant le chemin du fichier
    journal et la sécurité.

    Cette directive doit être utilisée avec précaution. Si

    ServerLimit et MaxRequestWorkers possèdent des valeurs
    supérieures à ce que le système peut supporter, ce dernier peut
    devenir instable ou Apache httpd peut tout simplement refuser de démarrer.
    

    
    Avec les MPMs prefork et event, n'utilisez cette directive
    que si vous devez définir MaxRequestWorkers à une valeur supérieure à

    La directive ThreadStackSize permet de
    définir la taille de la pile (pour les données propres) qu'utilisent
    les threads qui traitent les connexions clients en faisant appel à
    des modules. Dans la plupart des cas, la valeur par défaut de la
    taille de la pile du système d'exploitation convient, mais il existe
    certaines situations où il peut s'avérer nécessaire de l'ajuster
    :
    

    
      
      
    • Sur les plates-formes qui possèdent une valeur par défaut de
      taille de la pile relativement petite (par exemple HP-UX), Apache
      httpd peut se crasher si l'on utilise certains modules tiers qui
      possèdent un quantité de données propres stockées relativement
      importante. Il se peut que ces mêmes modules fonctionnent
      correctement sur d'autres plate-formes où la valeur par défaut de
      la taille de la pile est supérieure. Ce type de crash peut être
      evité en définissant ThreadStackSize à une
      valeur supérieure à la valeur par défaut du système
      d'exploitation. Ce type d'ajustement n'est nécessaire que si le
      fournisseur du module tiers en fait mention, ou si le diagnostic
      d'un crash d'Apache httpd indique que la taille de la pile était trop
      petite.
      • 

      
    • Sur les plates-formes où la taille par défaut de la pile des
      threads est sensiblement supérieure à la taille nécessaire pour la
      configuration du serveur web, il est possible de disposer d'un
      plus grand nombre de threads par processus enfant si la directive
      ThreadStackSize est définie à une valeur
      inférieure à la valeur par défaut du système d'exploitation.
      Cependant, ce
      type d'ajustement ne doit être effectué que dans un environnement
      de test permettant de qualifier le serveur web au maximum de ses
      possibilités, car il peut arriver, dans de rares cas, que des
      requêtes nécessitent une taille de pile supérieure pour pouvoir
      être traitées. La taille minimale requise pour la pile dépend
      fortement des modules utilisés, mais toute modification dans la
      configuration du serveur web peut invalider la définition courante
      de la directive ThreadStackSize.
      • 

      
    • Sous Linux, cette directive ne peut être utilisée que pour
      augmenter la valeur par defaut de la taille de la pile, car
      l'appel système sous-jacent utilise cette valeur comme taille de pile
      minimale. C'est la limite logicielle (souvent élevée)
      pour ulimit -s (8Mo si aucune limite) qui est
      utilisée comme taille de pile par défaut.
      • 
    
    

    
    Il est recommandé de ne pas réduire
    ThreadStackSize, à moins qu'un grand nombre
    de threads par processus enfant ne soit nécessaire. Sur certaines
    plates-formes (y compris Linux), une valeur de 128000 est déjà trop
    basse et provoque des crashes avec certains modules courants.

    Module Apache mod_xml2enc
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    Description:Support avancé de l'internationalisation et des jeux de
caractères pour les modules de filtrage basés sur libxml2
    

    Statut:Base
    

    Identificateur de Module:xml2enc_module
    

    Fichier Source:mod_xml2enc.c
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.2.x
    

    Sommaire
    

    
    Ce module fournit un support avancé de l'internationalisation
    pour les modules de filtrage supportant les balises (markup-aware)
    comme mod_proxy_html. Il est capable de détecter
    automatiquement l'encodage des données en entrée et de s'assurer
    qu'elle sont traitées correctement par l'interpréteur libxml2, y compris la conversion en
    Unicode (UTF-8) si nécessaire. Il peut aussi convertir les données
    dans l'encodage de votre choix après le traitement des balises, et
    s'assurera que le jeu de caractères approprié sera défini
    dans l'en-tête HTTP Content-Type.
    

    


    top
    

    

    Utilisation
    
    
    Il existe deux scénarios d'utilisation : le cas des modules
    programmés pour travailler avec mod_xml2enc ; et les autres :
    
    
    
    
    Modules de filtrages programmés pour mod_xml2enc
    
    
    Les modules comme mod_proxy_html versions 3.1 et
    supérieures utilisent la fonction optionnelle
    xml2enc_charset pour déterminer la valeur de l'argument
    "jeu de caractères" à transmettre à l'interpréteur libxml2, et
    disposent de la fonction optionnelle xml2enc_filter
    pour effectuer un encodage ultérieur éventuel. L'utilisation de
    mod_xml2enc avec un module préprogrammé à cet effet ne nécessite
    aucune configuration : ce dernier configurera mod_xml2enc pour vous
    (sachant que vous pouvez tout de même le personnaliser via les
    directives de configuration ci-dessous).
    
    
    
    
    Modules de filtrages non programmés pour mod_xml2enc
    
    
    Pour utiliser mod_xml2enc avec un module basé sur libxml2 qui n'a
    pas été explicitement programmé pour mod_xml2enc, vous devrez
    configurer la chaîne de filtrage vous-même. Ainsi, pour utiliser
    mod_xml2enc avec un filtre foo fourni par un module
    mod_foo et pour
    améliorer le support i18n de ce dernier avec HTML et XML, vous
    pouvez utiliser les directives suivantes :
    
    
    
    FilterProvider iconv    xml2enc Content-Type $text/html
    FilterProvider iconv    xml2enc Content-Type $xml
    FilterProvider markup   foo Content-Type $text/html
    FilterProvider markup   foo Content-Type $xml
    FilterChain     iconv markup
    
    
    
    mod_foo supportera alors tout jeu de caractère supporté soit par
    libxml2, soit par apr_xlate/iconv, soit par les deux.
    
    
    

    top
    

    

    API de programmation
    
    
    Les programmeurs de modules de filtrage basés sur libxml2 sont
    encouragés à les préprogrammer pour mod_xml2enc, afin de fournir un
    support i18n solide aux utilisateurs sans avoir à réinventer la
    roue. L'API de programmation est décrite dans
    mod_xml2enc.h, et mod_proxy_html est un
    exemple de son utilisation.
    

    top
    

    

    Détection et encodage
    
    
    A la différence de mod_charset_lite, mod_xml2enc
    est conçu pour travailler avec des données dont l'encodage ne peut
    pas être connu, et donc configuré, à l'avance. Il utilise donc les
    techniques de 'reniflage' suivantes pour détecter le type d'encodage
    des données HTTP :
    
    
      
        
    1. Si l'en-tête HTTP Content-Type contient un
	paramètre charset, c'est ce dernier qui sera utilisé.
      2. 
        
    2. Si les données commancent par une balise XML concernant
	l'ordre des octets (BOM) ou par une déclaration d'encodage XML,
	c'est celle-ci qui sera utilisée.
      3. 
        
    3. Si un type d'encodage est déclaré dans un élément HTML
	<META>, c'est ce dernier qui sera utilisé.
      4. 
        
    4. Si aucun des éléments précédents n'est trouvé, c'est la
	valeur par défaut définie par la directive
	xml2EncDefault qui sera utilisée.
      5. 
    
    
    
    Les conditions sont testées dans cet ordre . Dès qu'une règle
    s'applique, elle est utilisée et la détection est terminée.
    

    top
    

    

    Codage en sortie
    

    libxml2 utilise toujours UTF-8
(Unicode) en interne, et les modules de filtrage basés sur libxml2
utiliseront cet encodage en sortie par défaut. mod_xml2enc peut modifier
l'encodage en sortie via l'API, mais il n'y a actuellement aucun moyen de le
configurer directement.
    

    La modification de l'encodage en sortie ne devrait (du moins en théorie)
jamais être nécessaire, et est même déconseillée à cause de la charge de
traitement supplémentaire imposée au serveur par une conversion non
nécessaire.
    

    top
    

    

    Codages non supportés
    

    Si vous travaillez avec des encodages non supportés par aucune des
méthodes de conversion disponibles sur votre plateforme, vous pouvez
tout de même leur associer un alias vers un code supporté via la
directive xml2EncAlias.

    Directive xml2EncAlias
    

    

    Description:Définit des alias pour les valeurs d'encodage

    Statut:Base
    

    Module:mod_xml2enc
    

    
    
    Cette directive de niveau serveur permet de définir un ou
    plusieurs alias pour un encodage. Elle permet au support d'encodage de
    libxml2 de traiter en interne des encodages non reconnus par libxml2
    en utilisant la table de conversion pour un encodage reconnu. Elle
    permet d'atteindre deux objectifs : supporter des jeux (ou noms) de
    caractères non reconnus par libxml2 ou iconv, et éviter une
    conversion pour un encodage lorsque cela n'est pas nécessaire.

    Directive xml2EncDefault

    Si vous traitez des données dont l'encodage est connu, mais ne
    contenant aucune information à propos de ce dernier, vous pouvez
    définir une valeur par défaut afin d'aider mod_xml2enc à traiter
    correctement les données. Par exemple, pour définir la valeur par
    défaut Latin1 (iso-8859-1) specifiée dans HTTP/1.0,
    utilisez :
    
    
    xml2EncDefault iso-8859-1

    Directive xml2StartParse

    Cette directive permet de spécifier à partir de quelle balise,
    parmi les éléments spécifiés, l'interpréteur de balise doit
    commencer son traitement. Ccei permet de contourner le problème des
    serveurs d'arrière-plan qui insèrent des éléments non conformes en
    début de données, ce qui a pour effet de perturber l'interpréteur (voir un exemple ici).
    
    
    Elle ne doit être utilisée ni pour les documents XML, ni pour les
    documents HTML correctement formatés.

    Compatibility:Available for unix in version 2.3 and later
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the passing the socket of the
    client to another process.
    

    
    mod_proxy_fdpass uses the ability of AF_UNIX domain
    sockets to pass an
    open file descriptor to allow another process to finish handling a request.
    
    

    
    The module has a proxy_fdpass_flusher provider interface,
    which allows another module to optionally send the response headers, or even
    the start of the response body.  The default flush provider
    disables keep-alive, and sends the response headers, letting the external
    process just send a response body.
    
    
    
    
    In order to use another provider, you have to set the flusher
    parameter in the ProxyPass directive.
    
    

    
    At this time the only data passed to the external process is the client
    socket. To receive a client socket, call recvfrom with an allocated
    struct cmsghdr. Future versions of this module may include
    more data after the client socket, but this is not implemented at this time.

    Apache Module mod_proxy_http2

    Description:HTTP/2 support module for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_http2_module
    

    Source File:mod_proxy_http2.c
    

    Compatibility:Available in httpd 2.4.19 and later
    

    Summary
    

    
    mod_proxy_http2
    supports HTTP/2 only, it does not
    provide any downgrades to HTTP/1.1. This means that the backend
    needs to support HTTP/2 because HTTP/1.1 will not be used instead.
    

    
    This module requires the service of mod_proxy, so in order to get the ability of
    handling HTTP/2 proxy requests,
    mod_proxy and mod_proxy_http2
    need to be both loaded by the server.
    

    
    mod_proxy_http2 works with incoming fronted requests
    using HTTP/1.1 or HTTP/2. In both cases, requests proxied
    to the same backend are sent over a single TCP connection
    whenever possible (namely when the connection can be re-used).
    

    
    Caveat: there will be no attempt to consolidate multiple HTTP/1.1 
    frontend requests (configured to be proxied to the same backend)
    into HTTP/2 streams belonging to the same HTTP/2 request.
    Each HTTP/1.1 frontend request will be proxied to the backend using
    a separate HTTP/2 request (trying to re-use the same TCP connection
    if possible).
    

    
    This module relies on libnghttp2
    to provide the core http/2 engine.
    

    
    Warning
    
       
    This module is experimental. Its behaviors, directives, and 
       defaults are subject to more change from release to 
       release relative to other standard modules. Users are encouraged to 
       consult the "CHANGES" file for potential updates.
    
    
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.

    Basic Examples
    

    
    The examples below demonstrate how to configure HTTP/2 for
    backend connections for a reverse proxy. 
    

    
    HTTP/2 (TLS)
    ProxyPass "/app" "h2://app.example.com"
ProxyPassReverse "/app" "https://app.example.com"
    

    

    
    HTTP/2 (cleartext)
    ProxyPass "/app" "h2c://app.example.com"
ProxyPassReverse "/app" "http://app.example.com"
    

    

    
    
      
    The schemes to configure above in
      ProxyPassReverse for reverse proxying
      h2 (or h2c) protocols are the usual
      https (resp. http) as expected/used by
      the user agent.

    Request notes
    
    
    mod_proxy_http creates the following request notes for
        logging using the %{VARNAME}n format in
        LogFormat or
        ErrorLogFormat:
    
    
    
    
        
    proxy-source-port
    
        
    The local port used for the connection to the backend server.
    
        
    proxy-status
    
        
    The HTTP/2 status received from the backend server.

    Exemples
    

    
      
      
    1. 
        Enregistre un message après le traitement d'une requête pour
	/foo/* :

        
      <Location "/foo/">
  LogMessage "/foo/ has been requested"
</Location>
      

      
      2. 

      
    2. 
        Enregistre un message si une requête pour /foo/* est traitée
	dans une sous-requête :
        
      <Location "/foo/">
  LogMessage "subrequest to /foo/" hook=type_checker "expr=-T %{IS_SUBREQ}"
</Location>
      


        Le branchement (hook) par défaut log_transaction n'est pas
	exécuté pour les sous-requêtes ; nous devons donc en utiliser un
	autre.
      
      3. 


      
    3. 
        Enregistre un message si un client IPv6 est à l'origine d'un
	dépassement de délai pour une requête :
        
      LogMessage "IPv6 timeout from %{REMOTE_ADDR}" "expr=-T %{IPV6} && %{REQUEST_STATUS} = 408"
      

        Notez l'emplacement des guillemets pour l'argument
	expr=.
      
      4. 

      
    4. 
        Enregistre la valeur de la variable d'environnement de requête
	"X-Foo" à chaque étape du traitement :
        
      <Location "/">
  LogMessage "%{reqenv:X-Foo}" hook=all
</Location>
      

        En association avec les repères de temps en microsecondes du journal des erreurs,
	hook=all permet aussi de déterminer la durée d'exécution des
	différentes phases du traitement de la requête.

    Cette directive permet d'enregistrer un message personnalisé dans
    le journal des erreurs. Ce message peut utiliser des variables et
    des fonctions dans la syntaxe ap_expr.
    D'éventuelles références à des en-têtes HTTP dans l'expression
    rationnelle n'entraîneront pas l'ajout des noms d'en-tête
    correspondants à l'en-tête Vary.
    Les messages sont enregistrés au loglevel info.
    

    
    Le branchement (hook) précise la phase du traitement de la
    requête avant laquelle le message sera enregistré. Les branchements
    suivants sont supportés :
    

    
    Nom
    

    pre_translate_name
    

    translate_name
    

    type_checker
    

    quick_handler

    check_authn
    

    check_authz
    

    fixups
    

    handler
    

    log_transaction
    

    

    
    Le branchement par défaut est log_transaction. La
    valeur spéciale all est également supportée ; dans ce cas,
    le message sera enregistré à chaque phase. Tous les branchements ne
    sont pas exécutés pour chaque requête.
    

    
    L'expression optionnelle permet de restreindre l'enregistrement
    du message en fonction d'une certaine condition. La syntaxe de
    l'expression est décrite dans la documentation ap_expr. D'éventuelles
    références à des en-têtes HTTP dans l'expression
    rationnelle n'entraîneront pas l'ajout des noms d'en-tête
    correspondants à l'en-tête Vary.

    Description:Génération des en-têtes HTTP Expires et
Cache-Control en fonction de critères spécifiés par
l'utilisateur
    

    Statut:Extension
    

    Identificateur de Module:expires_module
    

    Fichier Source:mod_expires.c
    

    Sommaire
    

    
    Ce module permet de contrôler la définition de l'en-tête HTTP
    Expires et la directive max-age de
    l'en-tête HTTP Cache-Control dans les réponses du
    serveur. La date d'expiration peut être définie soit par rapport à
    la date de dernière modification du fichier source, soit
    par rapport à l'heure d'accès du client.
    

    
    Ces en-têtes HTTP permettent d'informer le client quant à la
    validité et à la persistence du document. S'il est présent dans le
    cache, et tant qu'il n'est pas arrivé à expiration, le document sera
    servi à partir de ce dernier, plutôt qu'à partir du document source.
    Après expiration, la copie du document dans le cache sera considérée
    comme "expirée" et donc invalide, et une nouvelle copie devra être
    obtenue à partir du document source.
    

    
    Pour modifier les directives de contrôle du cache autres
    que max-age (voir la RFC
    2616 section 14.9), vous pouvez utiliser la directive Header.
    

    
    Lorsque l'en-tête Expires est déjà présent dans la
    réponse générée par le serveur, par exemple s'il a été créé par un
    script CGI ou un serveur original via un serveur mandataire, ce
    module n'ajoute aucun en-tête Expires ou
    Cache-Control.
    

    


    top
    

    

    Autre syntaxe de définition de
l'intervalle
    
    
    Pour une syntaxe plus lisible, on peut aussi utiliser les
    directives ExpiresDefault et ExpiresByType comme suit :
    

    
    ExpiresDefault "base  [plus num type] [num type] ..."
ExpiresByType type/encoding "base  [plus num type] [num type] ..."
    


    
    où base peut être :
    

    
      
      
    • access
      • 

      
    • now (équivalent à
      'access')
      • 

      
    • modification
      • 
    
    

    
    Le mot-clé plus est optionnel. num doit
    correspondre à une valeur entière [compatible avec
    atoi()], et type peut être choisi parmi :
    

    
      
      
    • years
      • 
      
    • months
      • 
      
    • weeks
      • 
      
    • days
      • 
      
    • hours
      • 
      
    • minutes
      • 
      
    • seconds
      • 
    
    

    
    Par exemple, pour faire expirer par défaut les documents 1 mois
    après leur accès, on peut utiliser une des directives suivantes :
    
    
    ExpiresDefault "access plus 1 month"
ExpiresDefault "access plus 4 weeks"
ExpiresDefault "access plus 30 days"
    



    
    La date d'expiration peut être définie plus précisément en
    ajoutant plusieurs clauses 'num type' :
    

    
    ExpiresByType text/html "access plus 1 month 15 days 2 hours"
ExpiresByType image/gif "modification plus 5 hours 3 minutes"
    


    
    Notez que si vous utilisez une configuration basée sur la date de
    modification, l'en-tête Expires ne sera pas ajouté à un contenu qui
    ne provient pas directement d'un fichier sur disque ; et ceci tout
    simplement parce que ce type de contenu ne possède pas de date de
    modification.

    Directive ExpiresActive
    

    

    Description:Active la génération d'en-têtes
Expires
    

    Syntaxe:ExpiresActive On|Off
    

    Défaut:ExpiresActive Off
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Extension
    

    Module:mod_expires
    

    
    
    Cette directive permet d'activer ou de désactiver la génération
    des en-têtes Expires et Cache-Control pour
    les documents concernés ; en d'autres termes, si cette directive se
    trouve dans un fichier .htaccess, par exemple, elle ne
    s'applique qu'aux documents générés à partir du répertoire
    considéré. Si elle est définie à Off, les en-têtes ne
    seront générés pour aucun document du domaine considéré (sauf
    surcharge de la configuration à un niveau inférieur, comme un
    fichier .htaccess qui l'emporterait sur le fichier de
    configuration du serveur). Si elle est définie à On,
    les en-têtes seront ajoutés aux documents servis en fonction des
    critères définis par les directives ExpiresByType et ExpiresDefault (voir plus
    loin).
    

    
    Notez que cette directive ne permet pas de garantir qu'un en-tête
    Expires ou Cache-Control sera généré. Si
    les critères ne sont pas respectés, aucun en-tête ne sera généré, et
    la directive produira le même effet que si elle n'avait pas été
    définie.
    
 

    

    top
    

    Directive ExpiresByType
    

    

    Description:Définition de la valeur de l'en-tête Expires
en fonction du type MIME
    

    Syntaxe:ExpiresByType type MIME
<code>secondes
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Extension
    

    Module:mod_expires
    

    
    
    Cette directive permet de définir la valeur de l'en-tête
    Expires et de la directive max-age de
    l'en-tête Cache-Control générés pour les documents du
    type MIME spécifié (par exemple, text/html). Le second
    argument définit le nombre de secondes qui seront ajoutées à un
    temps de base pour calculer la date d'expiration.
    Cache-Control: max-age se calcule en soustrayant la
    date de la requête de la date d'expiration et s'exprime en
    secondes.
    

    
    Le champ <code> permet de spécifier
    quel temps doit être utilisé comme temps de base; M
    signifie que c'est la date
    de dernière modification du fichier qui doit être utilisée comme
    temps de base, alors que A signifie que c'est le moment
    où le client a accédé au document qui doit être utilisé comme temps
    de base.
    

    
    La différence d'effet est subtile. Si on utilise M,
    toutes les copies existantes du document dans tous les caches
    expireront au même moment, ce qui peut convenir par exemple pour une
    notice hebdomadaire qui correspond toujours à la même URL. Si on
    utilise A, la date d'expiration sera différente pour
    chaque client, ce qui peut convenir pour des fichiers d'images qui
    ne changent pas très souvent, et en particulier pour un ensemble de
    documents en relation qui se réfèrent tous aux mêmes images (ces
    images sont alors accédées de manière répétitive dans un intervalle
    de temps assez court).
    

    
    Exemple :
    # active la génération des en-têtes Expires
ExpiresActive On
# les images GIF expirent au bout d'un mois dans le cache du
# client
ExpiresByType image/gif A2592000
# les documents HTML restent valables une semaine après leur date
# de dernière modification
ExpiresByType text/html M604800
    

    

    
    Notez que cette directive ne produit d'effet que si
    ExpiresActive On a été spécifié. Elle l'emporte, mais
    seulement pour le type MIME spécifié, sur toute date
    d'expiration définie par la directive ExpiresDefault.
    

    
    Vous pouvez aussi définir le mode de calcul de la date
    d'expiration en utilisant une syntaxe
    alternative, comme décrit plus haut dans ce document.
    


    

    top
    

    Directive ExpiresDefault
    

    

    Description:Mode de calcul par défaut de la date
d'expiration
    

    Syntaxe:ExpiresDefault <code>secondes
    

    Contexte:configuration globale, serveur virtuel, répertoire, .htaccess
    

    Surcharges autorisées:Indexes
    

    Statut:Extension
    

    Module:mod_expires
    

    
    
    Cette directive permet de définir le mode de calcul par défaut de
    la date d'expiration pour tous les documents du domaine considéré.
    Elle peut être annulée pour certains types de documents par la
    directive ExpiresByType. Voir la description
    de cette dernière directive pour plus de détails à propos de la
    syntaxe de l'argument, ainsi que la description de la syntaxe alternative.

    Sommaire
    

    
    Avertissement
    
      
    Les modules de session font usage des cookies HTTP, et peuvent
      à ce titre être victimes d'attaques de type Cross Site Scripting,
      ou divulguer des informations à caractère privé aux clients.
      Veuillez vous assurer que les risques ainsi encourus ont été pris
      en compte avant d'activer le support des sessions sur votre
      serveur.
    
    
    

    
    Ce sous-module du module mod_session fournit le
    support du stockage des sessions utilisateur dans une base de
    données SQL en utilisant le module mod_dbd.
    

    
    Les sessions sont soit anonymes, et la session
    est alors identifiée par un UUID unique stocké dans un cookie au
    niveau du navigateur, soit propres à l'utilisateur,
    et la session est alors identifiée par l'identifiant de
    l'utilisateur connecté.
    

    
    Les sessions basées sur SQL sont dissimulées au navigateur, et
    permettent ainsi de préserver la confidentialité sans avoir recours
    au chiffrement.
    

    
    Plusieurs serveurs web d'une forêt de serveurs peuvent choisir de
    partager une base de données, et ainsi partager les sessions entre
    eux.
    

    
    Pour plus de détails à propos de l'interface des sessions, voir
    la documentation du module mod_session.

    Configuration de DBD
    

      
    Pour que le module mod_session_dbd puisse être
      configuré et maintenir une session, il faut tout d'abord
      configurer le module mod_dbd pour que le serveur
      puisse exécuter des requêtes vers la base de données.
    

      
    Quatre types de requêtes sont nécessaires pour maintenir une
      session, sélectionner ou mettre à jour une session existante,
      insérer une nouvelle session et supprimer une session vide ou
      arrivée à expiration. Ces requêtes sont configurées comme dans
      l'exemple suivant :
    

      
    Exemple de configuration de DBD
    DBDriver pgsql
DBDParams "dbname=apachesession user=apache password=xxxxx host=localhost"
DBDPrepareSQL "delete from session where key = %s" deletesession
DBDPrepareSQL "update session set value = %s, expiry = %lld, key = %s where key = %s" updatesession
DBDPrepareSQL "insert into session (value, expiry, key) values (%s, %lld, %s)" insertsession
DBDPrepareSQL "select value from session where key = %s and (expiry = 0 or expiry > %lld)" selectsession
DBDPrepareSQL "delete from session where expiry != 0 and expiry < %lld" cleansession
    

    

    
    top
    

    

    Sessions anonymes
    

      
    Les sessions anonymes sont identifiées par un UUID unique, et
      stockées dans un cookie au niveau du navigateur. Cette méthode est
      similaire à celle utilisée par la plupart des serveurs
      d'applications pour stocker les informations de session.
    

      
    Pour créer une session anonyme, la stocker dans une table de
      base de donnée postgres nommée apachesession, et
      sauvegarder l'identifiant de session dans un cookie nommé
      session, configurez la session comme suit :
    

      
    Session anonyme basée sur SQL
    Session On
SessionDBDCookieName session path=/
    

    

      
    Pour plus d'exemples sur la manière dont une application CGI
      peut accéder aux informations de session, voir la section exemples
      de la documentation du module mod_session.
    

      
    Pour des détails sur la manière dont une session peut être
      utilisée pour stocker des informations de type nom
      d'utilisateur/mot de passe, voir la documentation du module
      mod_auth_form.
    

    
    top
    

    

    Sessions propres à un
    utilisateur
    

      
    Les sessions propres à un utilisateur sont identifiées par le
      nom de l'utilisateur authentifié avec succès. Ceci permet
      d'assurer une confidentialité optimale, car aucun traitement
      externe à la session n'existe en dehors du contexte
      authentifié.
    

      
    Les sessions propres à un utilisateur ne fonctionnent que dans
      un environnement d'authentification correctement configuré, qu'il
      s'agisse d'une authentification de base, à base de condensés
      (digest) ou de certificats client SSL. Suite à des limitations
      dues à des dépendances mutuelles, les sessions propres à un
      utilisateur ne peuvent pas être utilisées pour stocker les données
      d'authentification en provenance d'un module comme
      mod_auth_form.
    

      
    Pour créer une session propre à un utilisateur, la stocker dans
      une table de base de données postgres nommée
      apachesession, avec comme clé de session l'identifiant
      utilisateur, ajoutez les lignes suivantes :
    

      
    Session propre à un utilisateur basée sur SQL
    Session On
SessionDBDPerUser On
    

    

    
    top
    

    

    Nettoyage de la base de
    données
    
      
    Avec le temps, la base de données va commencer à accumuler des
      sessions expirées. Pour le moment, le module
      mod_session_dbd n'est pas en mesure de gérer
      automatiquement l'expiration des sessions.
    

      
    Avertissement
    
      
    L'administrateur devra mettre en oeuvre un traitement externe
      via cron pour nettoyer les sessions expirées.

    de spécifier le nom et les attributs optionnels d'un cookie
    compatible RFC2965 qui contiendra l'identifiant de session. Les
    cookies RFC2965 sont définis à l'aide de l'en-tête HTTP
    Set-Cookie2.
    
    

    
    Une liste optionnelle d'attributs peut être spécifiée pour ce
    cookie, comme dans l'exemple ci-dessous. Ces attributs sont insérés
    dans le cookie tel quel, et ne sont pas interprétés par Apache.
    Assurez-vous que vos attributs sont définis correctement selon la
    spécification des cookies.

    La directive SessionDBDCookieRemove permet
    de déterminer si les cookies contenant l'identifiant de session
    doivent être supprimés des en-têtes pendant le traitement de la
    requête.
    

    
    Dans le cas d'un mandataire inverse où le serveur Apache sert de
    frontal à un serveur d'arrière-plan, révéler le contenu du cookie de
    session à ce dernier peut conduire à une violation de la
    confidentialité. À ce titre, si cette directive est définie à "on",
    le cookie de session sera supprimé des en-têtes HTTP entrants.

    Digest Authentication

    Source File:mod_auth_digest.c
    

    Summary
    

    
    This module implements HTTP Digest Authentication
    (RFC2617), and
    provides an alternative to mod_auth_basic where the
    password is not transmitted as cleartext. However, this does
    not lead to a significant security advantage over
    basic authentication. On the other hand, the password storage on the
    server is much less secure with digest authentication than with
    basic authentication. Therefore, using basic auth and encrypting the
    whole connection using mod_ssl is a much better
    alternative.
    

    


    top
    

    

    Using Digest Authentication
    

    
    To use MD5 Digest authentication, configure the location to be
    protected as shown in the below example:
    

    
    Example:
    <Location "/private/">
    AuthType Digest
    AuthName "private area"
    AuthDigestDomain "/private/" "http://mirror.my.dom/private2/"
    
    AuthDigestProvider file
    AuthUserFile "/web/auth/.digest_pw"
    Require valid-user
</Location>
    

    

    
    AuthDigestDomain
    should list the locations that will be protected by this
    configuration.
    

    
    The password file referenced in the AuthUserFile directive may be
    created and managed using the htdigest tool.
    


    
    Note
    
    
    Digest authentication was intended to be more secure than basic
    authentication, but no longer fulfills that design goal. A
    man-in-the-middle attacker can trivially force the browser to downgrade
    to basic authentication. And even a passive eavesdropper can brute-force
    the password using today's graphics hardware, because the hashing
    algorithm used by digest authentication is too fast. Another problem is
    that the storage of the passwords on the server is insecure. The contents
    of a stolen htdigest file can be used directly for digest authentication.
    Therefore using mod_ssl to encrypt the whole connection is
    strongly recommended.
    
    
    mod_auth_digest only works properly on platforms
      where APR supports shared memory.

    AuthDigestAlgorithm Directive
    

    

    Description:Selects the algorithm used to calculate the challenge and
response hashes in digest authentication
    

    Syntax:AuthDigestAlgorithm MD5|MD5-sess
    

    Default:AuthDigestAlgorithm MD5
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_auth_digest
    

    
    
    The AuthDigestAlgorithm directive
    selects the algorithm used to calculate the challenge and response
    hashes.
    

    
    
      MD5-sess is not correctly implemented yet.
    
    
    


    

    top
    

    AuthDigestDomain Directive
    

    

    Description:URIs that are in the same protection space for digest
authentication
    

    Syntax:AuthDigestDomain URI [URI] ...
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_auth_digest
    

    
    
    The AuthDigestDomain directive allows
    you to specify one or more URIs which are in the same protection
    space (i.e. use the same realm and username/password info).
    The specified URIs are prefixes; the client will assume
    that all URIs "below" these are also protected by the same
    username/password. The URIs may be either absolute URIs (i.e.
    including a scheme, host, port, etc.) or relative URIs.
    

    
    This directive should always be specified and
    contain at least the (set of) root URI(s) for this space.
    Omitting to do so will cause the client to send the
    Authorization header for every request sent to this
    server.
    

    
    The URIs specified can also point to different servers, in
    which case clients (which understand this) will then share
    username/password info across multiple servers without
    prompting the user each time. 
    


    

    top
    

    AuthDigestNonceLifetime Directive
    

    

    Description:How long the server nonce is valid
    

    Syntax:AuthDigestNonceLifetime seconds
    

    Default:AuthDigestNonceLifetime 300
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_auth_digest
    

    
    
    The AuthDigestNonceLifetime directive
    controls how long the server nonce is valid. When the client
    contacts the server using an expired nonce the server will send
    back a 401 with stale=true. If seconds is
    greater than 0 then it specifies the amount of time for which the
    nonce is valid; this should probably never be set to less than 10
    seconds. If seconds is less than 0 then the nonce never
    expires. 
    
    


    

    top
    

    AuthDigestProvider Directive
    

    

    Description:Sets the authentication provider(s) for this location
    

    Syntax:AuthDigestProvider provider-name
[provider-name] ...
    

    Default:AuthDigestProvider file
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_auth_digest
    

    
    
    The AuthDigestProvider directive sets
    which provider is used to authenticate the users for this location.
    The default file provider is implemented
    by the mod_authn_file module.  Make sure
    that the chosen provider module is present in the server.
    

    
    See mod_authn_dbm, mod_authn_file,
    mod_authn_dbd and mod_authn_socache
    for providers.
    


    

    top
    

    AuthDigestQop Directive
    

    

    Description:Determines the quality-of-protection to use in digest
authentication
    

    Syntax:AuthDigestQop none|auth|auth-int [auth|auth-int]
    

    Default:AuthDigestQop auth
    

    Context:directory, .htaccess
    

    Override:AuthConfig
    

    Status:Extension
    

    Module:mod_auth_digest
    

    
    
    The AuthDigestQop directive determines
    the quality-of-protection to use. auth will
    only do authentication (username/password); auth-int is
    authentication plus integrity checking (an MD5 hash of the entity
    is also computed and checked); none will cause the module
    to use the old RFC-2069 digest algorithm (which does not include
    integrity checking). Both auth and auth-int may
    be specified, in which the case the browser will choose which of
    these to use. none should only be used if the browser for
    some reason does not like the challenge it receives otherwise.
    

    
    
      auth-int is not implemented yet.
    
    


    

    top
    

    AuthDigestShmemSize Directive
    

    

    Description:The amount of shared memory to allocate for keeping track
of clients
    

    Syntax:AuthDigestShmemSize size
    

    Default:AuthDigestShmemSize 1000
    

    Context:server config
    

    Status:Extension
    

    Module:mod_auth_digest
    

    
    
    The AuthDigestShmemSize directive defines
    the amount of shared memory, that will be allocated at the server
    startup for keeping track of clients. Note that the shared memory
    segment cannot be set less than the space that is necessary for
    tracking at least one client. This value is dependent on your
    system. If you want to find out the exact value, you may simply
    set AuthDigestShmemSize to the value of
    0 and read the error message after trying to start the
    server.
    

    
    The size is normally expressed in Bytes, but you
    may follow the number with a K or an M to
    express your value as KBytes or MBytes. For example, the following
    directives are all equivalent:
    


    AuthDigestShmemSize 1048576
AuthDigestShmemSize 1024K
AuthDigestShmemSize 1M

    This document describes the terms that are used to describe
    each Apache configuration
    directive.
    

    


    top
    

    

    Description
    


    A brief description of the purpose of the directive.
    

    top
    

    

    Syntax
    

    
    This indicates the format of the directive as it would
    appear in a configuration file. This syntax is extremely
    directive-specific, and is described in detail in the
    directive's definition. Generally, the directive name is
    followed by a series of one or more space-separated arguments.
    If an argument contains a space, the argument must be enclosed
    in double quotes. Optional arguments are enclosed in square
    brackets. Where an argument can take on more than one possible
    value, the possible values are separated by vertical bars "|".
    Literal text is presented in the default font, while
    argument-types for which substitution is necessary are
    emphasized. Directives which can take a variable
    number of arguments will end in "..." indicating that the last
    argument is repeated.
    

    
    Directives use a great number of different argument types. A
    few common ones are defined below.
    

    
    
      
    URL
    

      
    A complete Uniform Resource Locator including a scheme,
      hostname, and optional pathname as in
      http://www.example.com/path/to/file.html
    

      
    URL-path
    

      
    The part of a url which follows the scheme and
      hostname as in /path/to/file.html. The
      url-path represents a web-view of a resource, as
      opposed to a file-system view.
    

      
    file-path
    

      
    The path to a file in the local file-system beginning
      with the root directory as in
      /usr/local/apache/htdocs/path/to/file.html.
      Unless otherwise specified, a file-path which does
      not begin with a slash will be treated as relative to the ServerRoot.
    

      
    directory-path
    

      
    The path to a directory in the local file-system
      beginning with the root directory as in
      /usr/local/apache/htdocs/path/to/.
    

      
    filename
    

      
    The name of a file with no accompanying path information
      as in file.html.
    

      
    regex
    

      
    A Perl-compatible regular
      expression. The directive definition will specify what the
      regex is matching against.
    

      
    extension
    

      
    In general, this is the part of the filename
      which follows the last dot. However, Apache recognizes
      multiple filename extensions, so if a filename
      contains more than one dot, each dot-separated part of the
      filename following the first dot is an extension.
      For example, the filename file.html.en
      contains two extensions: .html and
      .en. For Apache directives, you may specify
      extensions with or without the leading dot. In
      addition, extensions are not case sensitive.
    

      
    MIME-type
    

      
    A method of describing the format of a file which
      consists of a major format type and a minor format type,
      separated by a slash as in text/html.
    

      
    env-variable
    

      
    The name of an environment
      variable defined in the Apache configuration process.
      Note this is not necessarily the same as an operating system
      environment variable. See the environment variable documentation for
      more details.
    
    
    

    top
    

    

    Default
    

    
    If the directive has a default value (i.e., if you
    omit it from your configuration entirely, the Apache Web server
    will behave as though you set it to a particular value), it is
    described here. If there is no default value, this section
    should say "None". Note that the default listed here
    is not necessarily the same as the value the directive takes in
    the default httpd.conf distributed with the server.
    

    top
    

    

    Context
    

    
    This indicates where in the server's configuration files the
    directive is legal. It's a comma-separated list of one or more
    of the following values:
    

    
    
      
    server config
    

      
    This means that the directive may be used in the server
      configuration files (e.g., httpd.conf), but
      not within any
      <VirtualHost>
      or <Directory>
      containers. It is not allowed in .htaccess files
      at all.
    

      
    virtual host
    

      
    This context means that the directive may appear inside
      <VirtualHost>
      containers in the server
      configuration files.
    

      
    directory
    

      
    A directive marked as being valid in this context may be
      used inside <Directory>, <Location>, <Files>, <If>, and <Proxy> containers
      in the server configuration files, subject to the restrictions
      outlined in Configuration
      Sections.
    

      
    .htaccess
    

      
    If a directive is valid in this context, it means that it
      can appear inside per-directory
      .htaccess files. It may not be processed, though
      depending upon the overrides currently active.
    
    
    

    
    The directive is only allowed within the designated
    context; if you try to use it elsewhere, you'll get a
    configuration error that will either prevent the server from
    handling requests in that context correctly, or will keep the
    server from operating at all -- i.e., the server won't
    even start.
    

    
    The valid locations for the directive are actually the
    result of a Boolean OR of all of the listed contexts. In other
    words, a directive that is marked as being valid in
    "server config, .htaccess" can be used in the
    httpd.conf file and in .htaccess
    files, but not within any <Directory> or
    <VirtualHost>
    containers.
    

    top
    

    

    Override
    

    
    This directive attribute indicates which configuration
    override must be active in order for the directive to be
    processed when it appears in a .htaccess file. If
    the directive's context
    doesn't permit it to appear in .htaccess files,
    then no context will be listed.
    

    
    Overrides are activated by the AllowOverride directive, and apply
    to a particular scope (such as a directory) and all
    descendants, unless further modified by other
    AllowOverride directives at
    lower levels. The documentation for that directive also lists the
    possible override names available.
    

    top
    

    

    Status
    

    
    This indicates how tightly bound into the Apache Web server
    the directive is; in other words, you may need to recompile the
    server with an enhanced set of modules in order to gain access
    to the directive and its functionality. Possible values for
    this attribute are:
    

    
    
      
    Core
    

      
    If a directive is listed as having "Core" status, that
      means it is part of the innermost portions of the Apache Web
      server, and is always available.
    

      
    MPM
    

      
    A directive labeled as having "MPM" status is provided by
      a Multi-Processing Module. This
      type of directive will be available if and only if you are
      using one of the MPMs listed on the Module line of the directive
      definition.
    

      
    Base
    

      
    A directive labeled as having "Base" status is supported
      by one of the standard Apache modules which is compiled into
      the server by default, and is therefore normally available
      unless you've taken steps to remove the module from your
      configuration.
    

      
    Extension
    

      
    A directive with "Extension" status is provided by one of
      the modules included with the Apache server kit, but the
      module isn't normally compiled into the server. To enable the
      directive and its functionality, you will need to change the
      server build configuration files and re-compile Apache.
    

      
    Experimental
    

      
    "Experimental" status indicates that the directive is
      available as part of the Apache kit, but you're on your own
      if you try to use it. The directive is being documented for
      completeness, and is not necessarily supported. The module
      which provides the directive may or may not be compiled in by
      default; check the top of the page which describes the
      directive and its module to see if it remarks on the
      availability.
    
    
    

    top
    

    

    Module
    

    
    This quite simply lists the name of the source module which
    defines the directive.
    

    top
    

    

    Compatibility
    

    
    If the directive wasn't part of the original Apache version
    2 distribution, the version in which it was introduced should
    be listed here.  In addition, if the directive is available
    only on certain platforms, it will be noted here.

    Description:Réécrit les liens HTML afin de s'assurer qu'ils soient bien
adressables depuis les réseaux des clients dans un contexte de
mandataire.
    

    Statut:Base
    

    Identificateur de Module:proxy_html_module

    Sommaire
    

    
    Ce module fournit un filtre en sortie permettant de réécrire les liens
    HTML dans un contexte de mandataire, afin de s'assurer que ces liens
    fonctionnent pour les utilisateurs en dehors du mandataire. Il accomplit la
    même tâche que la directive ProxyPassReverse d'Apache accomplit pour les
    en-têtes HTTP, et fait partie des composants essentiels d'un mandataire
    inverse.
    


    Par exemple, si une entreprise possède un serveur d'applications
nommé appserver.example.com qui n'est visible que depuis son réseau
interne, et un serveur web public www.example.com, il peut
être souhaitable de fournir une passerelle vers le serveur d'application
à l'adresse http://www.example.com/appserver/. Lorsque le
serveur d'applications présente un lien vers lui-même, ce lien doit être
réécrit pour fonctionner à travers la passerelle. A cet effet,
mod_proxy_html permet de réécrire <a
href="http://appserver.example.com/foo/bar.html">foobar</a>
en <a
href="http://www.example.com/appserver/foo/bar.html">foobar</a>,
ce qui permet de rendre le serveur d'applications accessible depuis
l'extérieur.
    


    mod_proxy_html a été développé à l'origine à WebÞing, dont la documentation
détaillée pourra s'avérer utile aux utilisateurs.

    Directive ProxyHTMLBufSize
    

    

    Description:Définit l'incrément de la taille du tampon, ainsi que sa
taille initiale, pour la mise en
tampon des scripts en ligne et des feuilles de style.
    

    Syntaxe:ProxyHTMLBufSize nb-octets
    

    Défaut:ProxyHTMLBufSize 8192
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Pour pouvoir interpréter du contenu non HTML (feuilles de style et
scripts) embarqué dans des documents HTML, mod_proxy_html doit
le lire et le mémoriser en entier dans un
tampon. Ce tampon devra être étendu autant que nécessaire afin de
pouvoir accueillir le plus grand script ou la plus grande feuille de
style de la page, selon un incrément de nb-octets que cette
directive permet de définir.
    

    La valeur par défaut est 8192 et sera suffisante pour la plupart des
pages. Cependant, si vous savez que vous allez mandater des
pages contenant des feuilles de style et/ou scripts plus grands que 8k
(cette taille s'entend pour chaque script ou feuilles de style, non pour
leur ensemble), il sera plus efficace de définir une taille de
tampon initiale plus grande afin d'éviter d'avoir à le redimensionner
dynamiquement au cours du traitement d'une requête.

    Directive ProxyHTMLCharsetOut
    

    

    Description:Spécifie un jeu de caractères pour la sortie de
mod_proxy_html.
    

    Syntaxe:ProxyHTMLCharsetOut jeu-de-caractères | *
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Cette directive permet de spécifier un jeu de caractères pour la
sortie de mod_proxy_html. Elle ne devrait jamais être utilisée, car tout
changement par rapport à la valeur par défaut UTF-8 (Unicode -
utilisé en interne par libxml2) induit une charge supplémentaire de
traitement. La définition spéciale ProxyHTMLCharsetOut *
permet de générer une sortie qui utilisera le même encodage que
l'entrée.
    

    Notez que tout ceci ne fonctionne que si le module
mod_xml2enc est chargé.

    Directive ProxyHTMLDocType
    

    

    Description:Définit une déclaration de type de document HTML ou XHTML.
    

    Syntaxe:ProxyHTMLDocType HTML|XHTML [Legacy]
    OR

    ProxyHTMLDocType fpi [SGML|XML]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Avec la première syntaxe, les documents seront déclarés de type HTML
4.01 ou XHTML 1.0 selon l'option spécifiée. Cette option détermine aussi
si la syntaxe utilisée en sortie est HTML ou XHTML. Notez que le format
des documents en provenance du serveur d'arrière-plan n'est pas
important, car l'interpréteur le détectera automatiquement. Si le
second argument optionnel est défini à Legacy, les documents seront
déclarés de type "Transitional" ; cette option peut être nécessaire si
vous mandatez du contenu datant d'avant 1998, ou si vous travaillez avec
des outils de création/publication déficients.
    

    Avec la deuxième syntaxe, cette directive vous permet d'insérer votre
propre FPI (Formal Public Identifier). Le second argument optionnel
détermine si la syntaxe utilisée sera SGML/HTML ou XML/XHTML.
    

    Par défaut, aucun FPI n'est inséré, étant donné qu'il vaut mieux pas
de FPI du tout qu'un FPI bogué. Si par contre votre serveur d'arrière-plan
génère du contenu HTML ou XHTML correct, vous pouvez définir cette
directive en conséquence.
    

    Avec la première syntaxe, mod_proxy_html va aussi mettre le code HTML
en conformité avec le standard spécifié. Il ne pourra pas corriger
toutes les erreurs, mais il va supprimer les éléments et attributs non
conformes. Il peut aussi journaliser les autres erreurs si la directive
LogLevel est définie à
Debug.

    Directive ProxyHTMLEnable
    

    

    Description:Permet d'activer/désactiver le filtre proxy_html.
    

    Syntaxe:ProxyHTMLEnable On|Off
    

    Défaut:ProxyHTMLEnable Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    
    
    Cette directive est un simple commutateur permettant
    d'activer/désactiver le filtre proxy_html. Si
    mod_xml2enc est chargé, elle va aussi activer
    automatiquement le support de l'internationalisation.
    
    
    Notez que le filtre proxy_html s'agira que si les données sont de
    type HTML (Content-Type text/html ou application/xhtml+xml), et si
    elles passent par un mandataire. Vous pouvez passer outre ces
    contraintes (à vos risques et périls) en définissant la variable
    d'environnement PROXY_HTML_FORCE.

    Directive ProxyHTMLEvents
    

    

    Description:Spécifie les attributs à traiter comme des évènements de
type scripting.
    

    Syntaxe:ProxyHTMLEvents attribut [attribut ...]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Cette directive permet de spécifier un ou plusieurs attributs à
traiter comme
des évènements de type scripting et de leur appliquer les règles
ProxyHTMLURLMap lorsqu'elles ont été définies. Vous
pouvez spécifier un nombre quelconque d'attributs dans une ou plusieurs
directives ProxyHTMLEvents.
    

    Normalement, cette directive est définie globalement. Si vous
définissez ProxyHTMLEvents à plusieurs niveaux, certains niveaux
l'emportant sur d'autres, vous devrez spécifier un jeu complet
d'évènements pour chaque niveau.
    

    Le fichier proxy-html.conf fournit une configuration par
défaut et définit les évènements selon les standards
HTML 4 et XHTML 1.
    


    

    top
    

    Directive ProxyHTMLExtended
    

    

    Description:Détermine si l'on doit corriger les liens dans les scripts
en ligne, les feuilles de style et les évènements de type scripting.
    

    Syntaxe:ProxyHTMLExtended On|Off
    

    Défaut:ProxyHTMLExtended Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Si cette directive est définie à Off, les liens HTML
sont réécrits en fonction des directives
ProxyHTMLURLMap, mais les liens qui apparaissent
dans le code Javascript et les feuilles de style restent inchangés.
    

    Si elle est définie à On, tous les évènements de type
scripting (définis par la directive
ProxyHTMLEvents) et les scripts inclus ou les
feuilles de style sont aussi
traités par les règles ProxyHTMLURLMap, en
fonction des drapeaux définis pour chacune d'entre elles. Ne définissez
cette directive à On qu'en cas de nécessité absolue, car la
charge supplémentaire induite impacte les performances.
    

    Vous devez aussi prêter attention aux modèles de comparaison, car
l'interpréteur n'a aucune notion de la forme que pourrait prendre une URL dans un
script embarqué ou une feuille de style. En particulier, la comparaison
étendus du caractère / a de fortes chances d'induire des
correspondances erronées.
    


    

    top
    

    Directive ProxyHTMLFixups
    

    

    Description:Corrige les erreurs HTML simples.
    

    Syntaxe:ProxyHTMLFixups [lowercase] [dospath] [reset]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Cette directive accepte un à trois arguments parmi les suivants :
    

      

    • lowercase Les Urls sont réécrites en minuscules
      • 

    • dospath Les slashes inversés dans les URLs sont
remplacés par des slashes directs.
      • 

    • reset Annule toute option définie à un niveau supérieur
dans la configuration
      • 

    

    Cette directive doit être utilisée avec prudence. Elle peut corriger
certaines erreurs de création, mais risque aussi de modifier par erreur
des liens corrects. Ne l'utilisez que si vous êtes sûr que le serveur
d'arrière-plan est déficient.

    Directive ProxyHTMLInterp
    

    

    Description:Active la réinterprétation des règles
ProxyHTMLURLMap pour chaque requête.
    

    Syntaxe:ProxyHTMLInterp On|Off
    

    Défaut:ProxyHTMLInterp Off
    

    Contexte:configuration globale, serveur virtuel, répertoire

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    
    
    Cette directive permet d'activer le réinterprétation pour chaque
    requête des modèles source et cible de la directive
    ProxyHTMLURLMap.
    
    
    Si la réinterprétation n'est pas activée, toutes les règles sont
    précompilées au démarrage du serveur. Si elle est activée, les
    règles doivent être recompilées pour chaque requête, ce qui induit
    une charge de traitement supplémentaire. Elle ne doit donc être activée que si
    cela s'avère nécessaire.

    Cette directive permet de spécifier les éléments dont les attributs d'URL
doivent être réécrits en utilisant les règles standards ProxyHTMLURLMap. Vous devez définir une
directive ProxyHTMLLinks pour chaque élément, mais chacune d'entre elles peut
spécifier un nombre quelconque d'attributs
     
    Normalement, cette directive
est définie globalement. Si vous définissez ProxyHTMLLinks à plusieurs niveaux,
certains niveaux l'emportant sur d'autres, vous devrez spécifier un jeu complet
de liens pour chaque niveau.
     
    Le fichier proxy-html.conf
fournit une configuration par défaut et définit les liens HTML selon les
standards HTML 4 et XHTML 1.

    Directive ProxyHTMLMeta
    

    

    Description:Active ou désactive une préinterprétation supplémentaire
des métadonnées dans les sections HTML <head>.
    

    Syntaxe:ProxyHTMLMeta On|Off
    

    Défaut:ProxyHTMLMeta Off
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible à partir de la version 2.4 du serveur HTTP
Apache ; proposé en tant que module tiers dans les versions 2.x
précédentes.
    

    
    
    Cette directive permet d'activer ou désactiver une
    préinterprétation supplémentaire des métadonnées dans les sections
    HTML <head>. Si cette préinterprétation n'est pas
    requise, définissez ProxyHTMLMeta à Off et les performances
    seront légèrement améliorées. Cependant, elle s'avère parfois
    nécessaire pour assurer un fonctionnement correct de l'internationalisation.
    
    
    La directive ProxyHTMLMeta a deux effets. Le premier et le plus
    important est la détection des codages de caractères déclarés sous
    la forme
    
    
    <meta http-equiv="Content-Type" content="text/html;charset=foo">
    
    
    ou, dans le cas d'un document XHTML, sous la forme d'une
    déclaration XML. Elle n'est pas nécessaire si le jeu de caractères
    est déclaré explicitement dans un en-tête HTTP (ce qui est
    préférable) en provenance du serveur d'arrière-plan, ou si le
    document est en utf-8 (unicode) ou un de ses
    sous-ensembles comme ASCII. Vous pourrez aussi vous en passer
    lorsque le document utilise une valeur par défaut déclarée via la
    directive xml2EncDefault, avec le risque de
    propager une déclaration incorrecte. Une directive
    ProxyHTMLCharsetOut permettra d'annuler ce
    risque, mais pourra induire une surcharge de traitement supérieure à
    celle de ProxyHTMLMeta.
    
    
    Le deuxième effet est l'interprétation de toutes les déclarations
    <meta http-equiv=...> et leur conversion en
    en-têtes HTTP, afin de conserver le but original de cette forme
    de métaélément HTML.
    

    
    Avertissement
     Compte tenu du fait que la
    directive ProxyHTMLMeta promeut tous les éléments
    http-equiv au rang d'en-têtes HTTP, il est conseillé de ne
    l'activer que si vous faites autant confiance au contenu HTML qu'à votre
    serveur mandataire. Avec cette directive en effet, si ce contenu est géré
    par des gens malintentionnés, ces derniers seront en mesure d'injecter des
    en-têtes HTTP arbitraires et peut-être malveillants dans les réponses de
    votre serveur.

Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Si cette directive est définie à On, mod_proxy_html
supprimera les commentaires HTML. Notez que cela supprimera aussi tout
script ou style inclus dans les commentaires (une monstruosité
introduite en 1995/1996 avec Netscape 2 pour les navigateurs plus
anciens, et encore utilisée de nos jours). Cette directive peut aussi
interférer avec des processeurs basés sur les commentaires comme SSI ou
ESI : assurez-vous d'exécuter ces derniers avant mod_proxy_html
dans la chaîne de filtrage si vous supprimez les commentaires !

    Directive ProxyHTMLURLMap
    

    

    Description:Définit une règle de réécriture des liens HTML
    

    Syntaxe:ProxyHTMLURLMap modèle-source modèle-cible [drapeaux] [cond]
    

    Contexte:configuration globale, serveur virtuel, répertoire
    

    Statut:Base
    

    Module:mod_proxy_html
    

    Compatibilité:Disponible depuis la version 2.4 du serveur HTTP Apache.
Disponible en tant que module tiers dans les versions 2.x antérieures.
    

    

    Il s'agit de la directive la plus importante pour la réécriture des
liens HTML. Lors de l'interprétation d'un document, chaque fois qu'un
lien correspond à modèle-source, la partie du lien concernée
sera réécrite en modèle-cible, en tenant compte des
modifications induites par les drapeaux éventuellement spécifiés et par
la directive ProxyHTMLExtended.
Ne seront considérés comme des liens HTML que les éléments spécifiés via la
directive ProxyHTMLLinks.
    


    Le troisième argument optionnel permet de définir un des drapeaux
suivants (les drapeaux sont sensibles à la casse) :
    

    

    h
    

    Ignore les liens HTML (les traverse sans les modifier)
    

    e
    

    Ignore les évènements de scripting (les traverse sans les
modifier)
    

    c
    

    Traverse les sections de type style ou script sans les modifier.
    


    L
    

    Last-match. Si cette règle s'applique, aucune autre règle ne sera
prise en compte (notez qu'il s'agit du comportement automatique pour les
liens HTML).
    

    l
    

    L'opposé de L. Passe outre le comportement par défaut du
changement unique pour les liens HTML.
    

    R
    

    Utilise des expressions rationnelles pour les modèles.
modèle-source est une expression rationnelle, et
modèle-cible une chaîne de remplacement qui peut être basée
elle aussi sur une expression rationnelle. La mémorisation dans les
expressions rationnelles est supportée : vous pouvez utiliser des
parenthèses () dans le modèle-source, et récupérer la
correspondance de leur contenu via les variables $1 à $9 dans le
modèle-cible.
    


    Si le drapeau R n'est pas fourni, la directive utilisera des chaînes
littérales pour les différents modèles de recherche/remplacement. La
logique de recherche est "commence par" dans les liens HTML, et
"contient" dans les évènements de scripting et les sections de
type style ou script.

    

    

    x
    

    Utilise les expressions rationnelles étendues POSIX. Ne
s'applique qu'avec R.
    

    i
    

    Recherche de correspondance sensible à la casse. Ne
s'applique qu'avec R.
    


    n
    

    Désactive la mémorisation dans les expressions rationnelles (pour
améliorer les performances). Ne s'applique qu'avec R.
    

    s
    

    Recherche de correspondance dans les expressions rationnelles
basée sur la ligne. Ne s'applique qu'avec R.
    

    ^
    

    Recherche de correspondance au début seulement. Ne concerne que
les recherches de correspondance par rapport à des chaînes, et ne
s'applique pas aux liens HTML.
    

    $
    

    Recherche de correspondance à la fin seulement. Ne concerne que
les recherches de correspondance par rapport à des chaînes, et ne
s'applique pas aux liens HTML.
    

    V
    

    Insère des variables d'environnement dans le
modèle-cible. Un modèle-cible de la forme
${varname|default} sera remplacé par la valeur de la
variable d'environnement varname. Si cette dernière n'est
pas définie, modèle-cible sera remplacé par
default. La spécification de |default est
facultative.
    

    NOTE: l'insertion de variables d'environnement n'est possible que si
la directive ProxyHTMLInterp a été définie à
On.
    

    


    v
    

    Insère des variables d'environnement dans le
modèle-source. La syntaxe du modèle est identique à la
syntaxe précédente.
    

    NOTE: l'insertion de variables d'environnement n'est possible que si
la directive ProxyHTMLInterp a été définie à
On.
    

    

    


    Le quatrième argument optionnel cond définit une
condition qui sera évaluée pour chaque requête, sous réserve que la
directive ProxyHTMLInterp ait été définie à
On. Si la condition est évaluée à FALSE, la règle ne sera pas
appliquée à la requête. Si elle est évaluée à TRUE, ou si aucune
condition n'est définie, la règle s'applique.
    

    La condition est évaluée par l'interpréteur d'expression. La syntaxe simple des
conditions dans mod_proxy_html 3.x pour HTTPD 2.0 et 2.2 est aussi
supportée.

    Index par classes des directives autorisées dans .htaccess
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    
    
      Ceci est un index, organisé en classes, des directives autorisées dans les
      fichiers .htaccess pour différentes définitions de la directive AllowOverride. Il a pour but d'aider les
      administrateurs à contrôler les privilèges qu'ils accordent aux
      utilisateurs via les fichiers .htaccess. Pour une présentation de la
      manière dont fonctionnent les fichiers .htaccess, voir le tutoriel .htaccess.  
    
    

    
     Pour déterminer le jeu de directives que la configuration de votre
    serveur autorise aux utilisateurs dans les fichiers .htaccess : 
    

    
      
      
    1. Commencez par rechercher la présence d'une directive
      AllowOverrideList dans la section directory concernée. Sa
      définition vous indiquera la liste des directives autorisées (La valeur
      par défaut de cette directive est None).
      2. 
      
    2. Recherchez ensuite la présence d'une directive
      AllowOverride dans cette même section (sa valeur par défaut
      est None). Il y a tout d'abord deux cas particuliers :
        
        
          
      1. Si la directive AllowOverride est définie à
	  All, vous pouvez ajouter toutes les directives indiquées
	  sur cette page à la liste préexistante.
        2. 
          
      2. Si la directive AllowOverride est définie à
	  None, inutile d'aller plus loin. Seules les directives indiquées
	  par la directive AllowOverrideList (si elle est présente)
	  seront autorisées.
        3. 
        
      
      
      3. 
      
    3. En dehors de ces deux cas, la directive AllowOverride
      définit une liste de classes de directives (vous trouverez plus loin le
      jeu de directives correspondant à chacune de ces classes), et vous pourrez
      alors les ajouter à la liste définie par la directive
      AllowOverrideList.
      4. 
      
    4. Ajoutez enfin à la liste le jeu de directives toujours autorisées dans les
      fichiers .htaccess (elles sont listées dans la section All ci-dessous).
      5. 
    
    

    
    
      De nombreuses classes de directives sont assez puissantes et peuvent
      permettre aux utilisateurs des fichiers .htaccess de contrôler une grande
      partie du serveur. Pour une approche plus sure, définissez
      AllowOverride None, et utilisez la directive AllowOverrideList pour spécifier la liste exacte
      de directives que les utilisateurs de fichiers .htaccess pourront utiliser.

    Description:Extension de mod_proxy pour le traitement
des requêtes CONNECT
    

    Statut:Extension
    

    Identificateur de Module:proxy_connect_module
    

    Fichier Source:mod_proxy_connect.c
    

    Sommaire
    

    
    Pour fonctionner, ce module nécessite le chargement de
    mod_proxy. Il fournit le support de la méthode HTTP
    CONNECT. Cette méthode est principalement utilisée pour
    faire franchir les serveurs mandataires aux requêtes SSL à l'aide
    d'un tunnel.
    

    
    Ainsi, pour pouvoir traiter les requêtes CONNECT,
    mod_proxy et mod_proxy_connect
    doivent être chargés dans le serveur.
    

    
    CONNECT est aussi utilisée lorsque le serveur doit envoyer une
    requête HTTPS via un mandataire. Dans ce cas, le serveur se comporte
    comme un client CONNECT. Cette fonctionnalité étant fournie par le
    module mod_proxy, le module
    mod_proxy_connect n'est dans ce cas pas nécessaire.
    

    
    Avertissement
    
      
    N'activez pas la fonctionnalité de mandataire avant d'avoir sécurisé votre serveur. Les
      serveurs mandataires ouverts sont dangereux non seulement pour
      votre réseau, mais aussi pour l'Internet au sens large.

    Compatibilité:Déplacé depuis mod_proxy à partir
d'Apache 2.3.5. Plages de ports disponibles depuis Apache 2.3.7.
    

    
    
    La directive AllowCONNECT permet de
    spécifier une liste de numéros ou de plages de ports auxquels la
    méthode de mandataire CONNECT pourra se connecter. Les
    navigateurs récents utilisent cette méthode dans le cas où une
    connexion https est requise et où le tunneling
    mandataire sur HTTP est en service.
    

    
    Par défaut, seuls les ports par défauts https (443)
    et snews (563) sont pris en compte. Vous pouvez
    utiliser la directive AllowCONNECT pour
    outrepasser ces valeurs par défaut et n'autoriser les connexions que
    vers les ports spécifiés.

    Description:Module de stockage à base de cache d'objets partagés
(socache) pour le filtre de mise en cache HTTP.

    Identificateur de Module:cache_socache_module
    

    Fichier Source:mod_cache_socache.c
    

    Sommaire
    

    
    Le module mod_cache_socache implémente un
    gestionnaire de stockage à base de cache d'objets partagés (socache)
    pour le module mod_cache.
    

    
    Les en-têtes et corps des réponses mises en cache sont rassemblés
    et stockés sous une même clé dans le cache d'objets partagés. Il est
    possible de choisir entre plusieurs implémentations de caches d'objets
    partagés.
    

    
    Des réponses avec différents contenus négociés peuvent être
    stockées simultanément ; cependant, la mise en cache de contenus
    partiels n'est pas encore supportée par ce module.
    

    
    # Activation de la mise en cache
CacheSocache shmcb
CacheSocacheMaxSize 102400
<Location "/foo">
    CacheEnable socache

# Possibilité de se rabattre sur le cache disque
CacheSocache shmcb
CacheSocacheMaxSize 102400
<Location "/foo">
    CacheEnable socache
    CacheEnable disk
</Location>
    


    
    Note :
    
      
    Le module mod_cache_socache requiert les
      services du module mod_cache qui doit donc avoir
      été préalablement chargé.

    Le module mod_cache_socache ne tentera de mettre
    en cache que des réponses qui possèdent une taille de contenu
    explicite, ou dont la taille est suffisamment petite pour qu'elles
    soient écrites en une seule passe. Ceci permet au module
    mod_cache_disk de mettre en cache des réponses dont
    la taille est trop importante pour pouvoir être mises en cache par
    mod_cache_socache.

    Sommaire
    

    
    mod_slotmem_plain est un fournisseur de mémoire qui
    permet la création et l'utilisation d'un segment de mémoire contigu
    dans lequel les ensembles de données sont organisés en "slots".
    
    

    
    Si la mémoire doit être partagée entre des threads et des
    processus, il est préférable d'utiliser le fournisseur
    mod_slotmem_shm.
    
    

    
    mod_slotmem_plain fournit une API comprenant les
    fonctions suivantes :
    
    

   

    /* appelle le callback sur tous les slots actifs */
apr_status_t doall(ap_slotmem_instance_t *s, ap_slotmem_callback_fn_t *func, void *data, apr_pool_t *pool)      

/* crée un nouveau slot de mémoire dont chaque item aura une taille de item_size. */
apr_status_t create(ap_slotmem_instance_t **new, const char *name, apr_size_t item_size, unsigned int item_num, ap_slotmem_type_t type, apr_pool_t *pool)      

/* rattache à un slot de mémoire existant. */
apr_status_t attach(ap_slotmem_instance_t **new, const char *name, apr_size_t *item_size, unsigned int *item_num, apr_pool_t *pool)      

/* indique la mémoire associée à ce slot actif. */
apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void **mem)      

/* lit la mémoire depuis ce slot et la transfert vers dest */
apr_status_t get(ap_slotmem_instance_t *s, unsigned int item_id, unsigned char *dest, apr_size_t dest_len)      

/* écrit dans ce slot la mémoire en provenance de src */
apr_status_t put(ap_slotmem_instance_t *slot, unsigned int item_id, unsigned char *src, apr_size_t src_len)      

/* renvoie le nombre total de slots contenus dans ce segment */
unsigned int num_slots(ap_slotmem_instance_t *s)      

/* renvoie la taille totale des données, en octets, contenues dans un slot de ce segment */
apr_size_t slot_size(ap_slotmem_instance_t *s)      

/* alloue le premier slot libre et le marque comme utilisé (n'effectue aucune copie de données) */
apr_status_t grab(ap_slotmem_instance_t *s, unsigned int *item_id)      

/* appropriation ou allocation forcée du slot spécifié et marquage comme utilisé (n'effectue aucune copie de données) */
apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id)      
        
/* libère un slot et le marque comme non utilisé (n'effectue aucune copie de données) */

    Apache MPM prefork

    Description:Implements a non-threaded, pre-forking web server
    

    Status:MPM
    

    Module Identifier:mpm_prefork_module
    

    Source File:prefork.c
    

    Summary
    

    
    This Multi-Processing Module (MPM) implements a non-threaded,
    pre-forking web server. Each server process may answer incoming
    requests, and a parent process manages the size of the server pool.
    It is appropriate for sites that need to avoid
    threading for compatibility with non-thread-safe libraries.  It
    is also the best MPM for isolating each request, so that a problem
    with a single request will not affect any other.
    

    
    This MPM is very self-regulating, so it is rarely necessary to
    adjust its configuration directives.  Most important is that
    MaxRequestWorkers be big enough
    to handle as many simultaneous requests as you expect to receive, but
    small enough to assure that there is enough physical RAM for all
    processes.
    

    


    top
    

    

    How it Works
    
    
    A single control process is responsible for launching child
    processes which listen for connections and serve them when they
    arrive. Apache httpd always tries to maintain several spare
    or idle server processes, which stand ready to serve incoming
    requests. In this way, clients do not need to wait for a new
    child processes to be forked before their requests can be
    served.
    

    
    The StartServers,
    MinSpareServers,
    MaxSpareServers, and
    MaxRequestWorkers regulate how
    the parent process creates children to serve requests. In general,
    Apache httpd is very self-regulating, so most sites do not need to
    adjust these directives from their default values. Sites which
    need to serve more than 256 simultaneous requests may need to
    increase MaxRequestWorkers,
    while sites with limited memory may need to decrease MaxRequestWorkers to keep the server from
    thrashing (swapping memory to disk and back). More information
    about tuning process creation is provided in the performance hints
    documentation.
    

    
    While the parent process is usually started as root
    under Unix in order to bind to port 80, the child processes are
    launched by Apache httpd as a less-privileged user. The User and Group directives are used to set
    the privileges of the Apache httpd child processes. The child processes
    must be able to read all the content that will be served, but
    should have as few privileges beyond that as possible.
    

    
    MaxConnectionsPerChild
    controls how frequently the server recycles processes by killing
    old ones and launching new ones.
    

    
    This MPM uses the mpm-accept mutex to serialize
    access to incoming connections when subject to the thundering herd
    problem (generally, when there are multiple listening sockets).
    The implementation aspects of this mutex can be configured with the
    Mutex directive.  The performance hints
    documentation has additional information about this mutex.

    MaxSpareServers Directive
    

    

    Description:Maximum number of idle child server processes
    

    Syntax:MaxSpareServers number
    

    Default:MaxSpareServers 10
    

    Context:server config
    

    Status:MPM
    

    Module:prefork
    

    
    
    The MaxSpareServers directive sets the
    desired maximum number of idle child server processes. An
    idle process is one which is not handling a request. If there are
    more than MaxSpareServers idle, then the
    parent process will kill off the excess processes.
    

    
    Tuning of this parameter should only be necessary on very
    busy sites. Setting this parameter to a large number is almost
    always a bad idea. If you are trying to set the value equal to or lower than
    MinSpareServers, Apache HTTP Server
    will automatically adjust it to MinSpareServers + 1.

    MinSpareServers Directive
    

    

    Description:Minimum number of idle child server processes
    

    Syntax:MinSpareServers number
    

    Default:MinSpareServers 5
    

    Context:server config
    

    Status:MPM
    

    Module:prefork
    

    
    
    The MinSpareServers directive sets the
    desired minimum number of idle child server processes. An
    idle process is one which is not handling a request. If there are
    fewer than MinSpareServers idle, then the parent
    process creates new children: It will spawn one, wait a second, then spawn
    two, wait a second, then spawn four, and it will
    continue exponentially until it is spawning 32 children per second. It will
    stop whenever it satisfies the MinSpareServers
    setting.
    

    
    Tuning of this parameter should only be necessary on very
    busy sites. Setting this parameter to a large number is almost
    always a bad idea.

    Apache Module mod_heartmonitor
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:Centralized monitor for mod_heartbeat origin servers
    

    Status:Experimental
    

    Module Identifier:heartmonitor_module
    

    Source File:mod_heartmonitor.c
    

    Compatibility:Available in Apache 2.3 and later
    

    Summary
    


    
mod_heartmonitor listens for server status messages generated
by mod_heartbeat enabled origin servers and makes their status
available to mod_lbmethod_heartbeat. This allows
ProxyPass to use the "heartbeat"
lbmethod inside of ProxyPass.

    


    This module uses the services of mod_slotmem_shm when
available instead of flat-file storage.  No configuration is required to
use mod_slotmem_shm.
    

    
    
        To use mod_heartmonitor,
        mod_status and mod_watchdog
        must be either a static modules or, if a dynamic module, it must
        be loaded before mod_heartmonitor.

    HeartbeatListen Directive
    

    

    Description:multicast address to listen for incoming heartbeat requests 
    

    Syntax:HeartbeatListen addr:port
    

    Default:disabled
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_heartmonitor
    

    
    
    The HeartbeatListen directive specifies the
    multicast address on which the server will listen for status information from
    mod_heartbeat-enabled servers.  This
    address will usually correspond to a configured  HeartbeatAddress on an origin server.
    
    

    
    HeartbeatListen 239.0.0.1:27999
    


    
     This module is inactive until this directive is used.

    HeartbeatMaxServers Directive
    

    

    Description:Specifies the maximum number of servers that will be sending
heartbeat requests to this server
    

    Syntax:HeartbeatMaxServers number-of-servers
    

    Default:HeartbeatMaxServers 10
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_heartmonitor
    

    
    
    The HeartbeatMaxServers directive specifies the
    maximum number of servers that will be sending requests to this monitor
    server.  It is used to control the size of the shared memory allocated
    to store the heartbeat info when mod_slotmem_shm is in use.

    HeartbeatStorage Directive
    

    

    Description:Path to store heartbeat data
    

    Syntax:HeartbeatStorage file-path
    

    Default:HeartbeatStorage logs/hb.dat
    

    Context:server config
    

    Status:Experimental
    

    Module:mod_heartmonitor
    

    
    
    The HeartbeatStorage directive specifies the
    path to store heartbeat data.  This flat-file is used only when
    mod_slotmem_shm is not loaded.

    Apache HTTP Server Version 2.4

    Allgemeine Direktiven der Apache-MPMs
    

    

    Verfügbare Sprachen:  de  |

    Diese Übersetzung ist möglicherweise
            nicht mehr aktuell. Bitte prüfen Sie die englische Version auf
            die neuesten Änderungen.
    

    Beschreibung:Eine Sammlung von Direktiven, die in mehr als einem
  Multi-Processing-Modul (MPM) implementiert sind.
    

    Status:MPM
    

    



    top
    

    CoreDumpDirectory-Direktive
    

    

    Beschreibung:Verzeichnis, in das der Apache zu wechseln versucht, bevor er
  einen Hauptspeicherauszug erstellt
    

    Syntax:CoreDumpDirectory Verzeichnis
    

    Voreinstellung:Für die Voreinstellung siehe Beschreibung
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:beos, leader, mpm_winnt, perchild, prefork, threadpool, worker
    

    
    
    Dies beeinflusst das Verzeichnis, in welches der Apache zu wechseln
    versucht, bevor er einen Hauptspeicherauszug (Anm.d.Ü.: einen
    so genannten Core-Dump) erstellt. Die Voreinstellung ist das
    ServerRoot-Verzeichnis. Da dieses
    jedoch nicht für den Benutzer beschreibbar sein soll, unter dem
    der Server läuft, werden normalerweise keine
    Hauptspeicherauszüge geschrieben. Wenn Sie zum Debuggen
    einen Hauptspeicherauszug haben möchten, können Sie
    ihn mit dieser Direktive an einem anderen Ort ablegen lassen.
    

    
    Hauptspeicherauszüge unter Linux
    
      
    Wenn Apache als root startet und zu einem anderen Benutzer 
      wechselt, deaktiviert der Linux-Kernel Hauptspeicherauszüge
      auch dann, wenn der Prozess in dem Verzeichnis schreiben darf. Ab Linux
      2.4 reaktiviert Apache (ab 2.0.46) Hauptspeicherauszüge wieder,
      jedoch nur dann, wenn Sie explizit
      CoreDumpDirectory konfigurieren.

    EnableExceptionHook-Direktive
    

    

    Beschreibung:Aktiviert einen Hook, der nach einem Absturz noch
Ausnahmefehler behandeln lassen kann
    

    Syntax:EnableExceptionHook On|Off
    

    Voreinstellung:EnableExceptionHook Off
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:leader, perchild, prefork, threadpool, worker
    

    Kompatibilität:Verfügbar seit Version 2.0.49
    

    
    
    Diese Direktive ist aus Sicherheitsgründen nur verfügbar,
    wenn der Server mit der Option --enable-exception-hook
    konfiguriert wurde. Sie aktiviert einen Hook, der es externen Modulen
    erlaubt, sich dort einzuhängen und nach dem Absturz eines
    Kindprozesses noch Aktionen durchzuführen.
    

    
    Es existieren bereits zwei Module, mod_whatkilledus und
    mod_backtrace, welche diesen Hook verwenden. Weitere
    Informationen hierzu finden Sie auf Jeff Trawicks EnableExceptionHook-Seite.

    GracefulShutdownTimeout-Direktive
    

    

    Beschreibung:Specify a timeout after which a gracefully shutdown server
will exit.
    

    Syntax:GracefulShutdownTimeout seconds
    

    Voreinstellung:GracefulShutdownTimeout 0
    

    Kontext:Serverkonfiguration

            Version.

    Listen-Direktive
    

    

    Beschreibung:IP-Adressen und Ports, an denen der Server lauscht
    

    Syntax:Listen [IP-Addresse:]Port
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:beos, leader, mpm_netware, mpm_winnt, mpmt_os2, perchild, prefork, threadpool, worker
    

    Kompatibilität:Seit Apache 2.0 vorgeschrieben
    

    
    
    Die Direktive Listen weist den Apache an,
    nur an den angegebenen IP-Adressen oder Ports zu lauschen.
    Standardmäßig antwortet er auf alle Anfragen an allen
    IP-Interfaces. Listen ist nun eine notwendige
    Anweisung. Wenn sie nicht in der Konfigurationsdatei enthalten ist,
    wird der Server-Start fehlschlagen. Dies ist eine Änderung
    gegenüber früheren Versionen des Apache.
    

    
    Die Direktive Listen weist den Server an,
    ankommende Anfragen am angegebenen Port oder der
    Kombination aus Adresse und Port entgegenzunehmen. Wenn nur eine Portnummer
    angegeben ist, dann lauscht der Server am angegebenen Port an allen
    Interfaces. Wenn sowohl eine IP-Adresse als auch ein Port angegeben
    sind, dann lauscht der Server am angegeben Port und Interface.
    

    
    Es können mehrere Listen-Anweisungen
    verwendet werden, um eine Reihe von Adressen und Port anzugeben, an
    denen gelauscht werden soll. Der Server antwortet auf Anfragen von
    jedem der aufgeführten Adressen und Ports.
    

    
    Um beispielsweise den Server Verbindungen an den beiden Ports 80 und
    8000 annehmen zu lassen, verwenden Sie:
    

    
    
      Listen 80
    
      Listen 8000
    
    

    
    Um den Server Verbindungen an zwei angegebenen Interfaces und Ports
    annehmen zu lassen, verwenden Sie:
    

    
    
      Listen 192.170.2.1:80
    
      Listen 192.170.2.5:8000
    
    

    
    IPv6-Adressen müssen wie in dem folgenden Beispiel in eckige
    Klammern eingeschlossen werden:
    

    
    
      Listen [2001:db8::a00:20ff:fea7:ccea]:80
    
    

    
    Fehlermöglichkeit
    
      Mehrere Listen-Direktiven für gleiche
      IP-Adresse und Port führen zur Fehlermeldung
      Address already in use (Anm.d.Ü.: Adresse schon in
      Benutzung).

    ListenBackLog-Direktive
    

    

    Beschreibung:Maximale Länge der Warteschlange schwebender
  Verbindungen
    

    Syntax:ListenBacklog backlog
    

    Voreinstellung:ListenBacklog 511
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:beos, leader, mpm_netware, mpm_winnt, mpmt_os2, perchild, prefork, threadpool, worker
    

    
    
    Die maximale Länge der Warteschlange schwebender Verbindungen.
    Üblicherweise ist keine Feineinstellung notwendig oder sinnvoll,
    auf einigen System kann es jedoch gewünscht sein, diesen Wert bei
    TCP-SYN-Angriffen zu erhöhen. Beachten Sie auch die Beschreibung des
    backlog-Parameters der Systemfunktion listen(2).
    

    
    Der Wert wird vom Betriebssystem oft auf eine niedrigere
    Einstellung begrenzt. Dies variiert von Betriebssystem zu Betriebssystem.
    Beachten Sie auch, dass viele Betriebssyteme nicht genau beachten,
    was für backlog angegeben ist, jedoch einen Wert basierend auf der
    Angabe (normalerweiseweise jedoch größer als diese) verwenden.

    MaxSpareThreads-Direktive
    

    

    Beschreibung:Maximale Anzahl unbeschäftigter Threads
    

    Syntax:MaxSpareThreads Anzahl
    

    Voreinstellung:Für Details siehe Beschreibung
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:beos, leader, mpm_netware, mpmt_os2, perchild, threadpool, worker
    

    
    
    Maximale Anzahl unbeschäftigter Threads. Die verschiedenen MPMs
    behandeln diese Anweisung unterschiedlich.
    

    
    Die Voreinstellung für perchild ist
    MaxSpareThreads 10. Das MPM überwacht die Anzahl der
    unbeschäftigten Threads auf der Basis einzelner Kindprozesse. Wenn
    zu viele unbeschäftigte Threads in einem Kindprozess existieren,
    beendet der Server Threads innerhalb dieses Kindprozesses.
    

    
    Die Voreinstellung für worker,
    leader und threadpool ist
    MaxSpareThreads 250. Diese MPMs behandeln Threads
    auf einer serverweiten Basis. Wenn zu viele unbeschäftigte Threads
    im Server existieren, dann werden solange Kindprozesse beendet, bis
    die Anzahl der unbeschäftigten Threads kleiner als der
    angegebene Wert ist.
    

    
    Die Voreinstellung für mpm_netware ist
    MaxSpareThreads 100. Da dieses MPM nur einen einzigen
    Prozess ausführt, ist die Zählung überschüssiger
    Threads ebenfalls serverweit.
    

    
    beos and mpmt_os2 arbeiten
    ähnlich wie mpm_netware. Die Voreinstellung
    für beos ist MaxSpareThreads 50.
    Die Voreinstellung für mpmt_os2 ist
    10.
    

    
    Restriktionen
    
      
    Der Wertebereich von MaxSpareThreads
      ist eingeschränkt. Apache korrigiert den angegebenen Wert
      automatisch gemäß den folgenden Regeln:

    Modul:beos, leader, mpm_netware, mpmt_os2, perchild, threadpool, worker
    

    
    
    Minimale Anzahl unbeschäftigter Threads, um Anfragespitzen
    zu bedienen. Die verschiedenen MPMs behandeln die Anweisung
    unterschiedlich.
    

    
    perchild verwendet die Voreinstellung
    MinSpareThreads 5 und überwacht die Anzahl der
    unbeschäftigten Threads auf der Basis einzelner Kindprozesse. Wenn
    in einem Kindprozess nicht genügend unbeschäftigte
    Threads vorhanden sind, erstellt der Server neue Threads innerhalb
    dieses Kindprozesses. Wenn Sie also NumServers auf 10 und MinSpareThreads auf einen Wert von 5 setzen,
    haben Sie mindestens 50 unbeschäftigte Threads auf Ihrem
    System.
    

    
    worker, leader und
    threadpool verwenden eine Voreinstellung von
    MinSpareThreads 75 und behandeln unbeschäftigte
    Threads auf serverweiter Basis. Wenn nicht genügend
    unbeschäftigte Threads im Server vorhanden sind, dann
    werden solange Kindprozesse erzeugt, bis die Anzahl unbeschäftigter
    Threads größer als der angegebene Wert ist.
    

    
    mpm_netware verwendet die Voreinstellung
    MinSpareThreads 10 und verfolgt dies serverweit, da
    es ein Einzelprozess-MPM ist.
    

    
    beos und mpmt_os2 arbeiten
    ähnlich wie mpm_netware. Die Voreinstellung
    für beos ist MinSpareThreads 1.
    Die Voreinstellung für mpmt_os2 ist
    5.

    PidFile-Direktive
    

    

    Beschreibung:Datei, in welcher der Server die Prozess-ID des Daemons
ablegt
    

    Syntax:PidFile Dateiname
    

    Voreinstellung:PidFile logs/httpd.pid
    

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:beos, leader, mpm_winnt, mpmt_os2, perchild, prefork, threadpool, worker
    

    
    
    Die Direktive PidFile bestimmt die Datei,
    in welcher der Server die Prozess-ID des Daemons ablegt. Wenn der
    Dateiname nicht absolut angegeben wird, wird er relativ zu
    ServerRoot interpretiert.
    

    
    Beispiel
    
      PidFile /var/run/apache.pid
    
    

    
    Es ist oft hilfreich, dem Server ein Signal senden zu können,
    damit er seine ErrorLogs und
    TransferLogs
    schließt und dann neu öffnet und seine
    Konfigurationsdateien neu einliest. Dies kann durch Senden eines
    SIGHUP-Signals (kill -1) an die Prozess-ID geschehen, die im
    PidFile eingetragen ist.
    

    
    Die PidFile-Datei unterliegt den
    gleichen Warnungen über die Ablage von Protokolldateien
    und Sicherheit.
    

    
    Anmerkung
    
      
    Ab Apache 2 wird empfohlen, nur das Skript apachectl zum (Neu-)Starten und Stoppen des Servers zu
      verwenden.

  Koordinierung der Kindprozesse verwendet wird
    

    Syntax:ScoreBoardFile Dateipfad

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:beos, leader, mpm_winnt, perchild, prefork, threadpool, worker
    

    
    
    Apache verwendet ein Scoreboard zur Kommunikation zwischen
    seinen Eltern- und Kindprozessen. Einige Architekturen erfordern
    eine Datei zur Unterstützung der Kommunikation. Wenn die Datei
    undefiniert bleibt, versucht der Apache zuerst, das Scoreboard im
    Arbeitsspeicher  zu erstellen (Verwendung von anonymem Shared-Memory),
    und versucht bei einem Fehlschlag anschließend die Datei auf
    der Festplatte zu erstellen (Verwendung von Datei-basiertem
    Shared-Memory). Die Angabe dieser Direktive veranlaßt den
    Apache stets, die Datei auf der Festplatte zu erstellen.
    

    
    Beispiel
    
      ScoreBoardFile /var/run/apache_status
    
    

    
    Datei-basiertes Shared-Memory ist für Applikationen von
    Drittanbietern hilfreich, die direkten Zugriff auf das Scoreboard
    benötigen.
    

    
    Wenn Sie eine ScoreBoardFile-Anweisung
    verwenden, erreichen Sie eventuell eine höhere Geschwindigkeit, wenn
    Sie die Datei auf einer RAM-Disk ablegen. Achten Sie darauf, die
    gleichen Warnungen wie über die Ablage von Protokolldateien und
    Sicherheit zu beherzigen.

    Der Server setzt die Größe des TCP-Puffers auf die
    angegebene Anzahl Bytes. Dies ist sehr hilfreich, um Voreinstellungen
    alter Standardbetriebssysteme für Hochgeschwindigkeitsverbindungen
    mit hoher Latenzzeit anzuheben (d.h. 100ms oder so, wie bei
    Interkontinentalverbindungen).
    

    
    Wird der Wert auf 0 gesetzt, dann verwendet der Server
    die Voreinstellung des Betriebssystems.

    Kontext:Serverkonfiguration
    

    Status:MPM
    

    Modul:leader, perchild, prefork, threadpool, worker
    

    
    
    Bei dem MPM prefork bestimmt die Direktive
    den während der Lebensdauer des Apache-Prozesses maximal
    einstellbaren Wert für MaxClients. Beim MPM
    worker bestimmt die Direktive in Verbindung mit
    ThreadLimit den Maximalwert
    für MaxClients
    für die Lebensdauer des Apache-Prozesses. Jeder Versuch, diese
    Anweisung während eines Neustarts zu ändern, wird ignoriert.
    MaxClients kann jedoch
    während eines Neustarts geändert werden.
    

    
    Lassen Sie besondere Vorsicht bei der Verwendung dieser Direktive
    walten. Wenn ServerLimit auf einen Wert deutlich
    höher als notwendig gesetzt wird, wird zusätzliches,
    unbenutztes Shared-Memory belegt. Wenn sowohl
    ServerLimit als auch MaxClients auf Werte gesetzt werden, die
    größer sind, als das System sie handhaben kann, dann kann
    der Apache möglicherweise nicht starten, oder das System kann
    instabil werden.
    

    
    Verwenden Sie die Direktive bei dem MPM prefork
    nur, wenn Sie MaxClients
    auf mehr als 256 (Voreinstellung) setzen müssen. Setzen Sie den
    Wert nicht höher als den Wert, den Sie für MaxClients angeben möchten.
    

    
    Verwenden Sie die Direktive bei worker,
    leader und threadpool nur, wenn Ihre
    MaxClients- und
    ThreadsPerChild-Einstellungen
    mehr als 16 Serverprozesse (Voreinstellung) erfordern. Setzen Sie den
    Wert dieser Direktive nicht höher, als die Anzahl der Serverprozesse,
    die dafür erforderlich ist, was Sie bei MaxClients und
    ThreadsPerChild angeben
    möchten.
    

    
    Verwenden Sie die Direktive beim MPM perchild nur,
    wenn Sie NumServers auf einen
    Wert größer als 8 (Voreinstellung) setzen müssen.
    

    
    Anmerkung
    
      
    Eine feste Begrenzung von ServerLimit 20000 ist in den
      Server einkompiliert (bei dem MPM prefork 200000).
      Dies soll unangenehme Effekte durch Tippfehler verhindern.

    kann jedoch während eines Neustarts modifiziert werden bis zu dem
    Wert dieser Anweisung.
    

    
    Lassen Sie besondere Vorsicht bei der Verwendung dieser Direktive
    walten. Wenn ThreadLimit auf einen Wert
    deutlich höher als ThreadsPerChild gesetzt wird, wird
    zusätzliches, ungenutztes Shared-Memory belegt. Wenn sowohl
    ThreadLimit als auch ThreadsPerChild auf Werte gesetzt werden,
    die größer sind, als das System sie handhaben kann, dann kann
    der Apache möglicherweise nicht starten oder das System kann
    instabil werden. Setzen Sie den Wert dieser Direktive nicht höher
    als Ihre größte erwartete Einstellung für

    während der aktuellen Ausführung des Apache.
    

    
    Die Voreinstellung für ThreadLimit ist

    Kindprozess gestartet werden. Der Kindprozess erstellt diese Threads
    beim Start und erstellt später keine weiteren mehr. Wenn Sie ein
    MPM wie mpm_winnt verwenden, wo nur ein
    Kindprozess existiert, dann sollte diese Angabe hoch genug sein,
    die gesamte Last des Servers zu bewältigen. Wenn Sie ein MPM
    wie worker verwenden, wo mehrere Kindprozesse
    existieren, dann sollte die Gesamtzahl der Thread groß
    genug sein, die übliche Last auf dem Server zu bewältigen.

    Kompatibilität:Verfügbar seit Version 2.1
    

    
    
    Die Direktive ThreadStackSize legt die
    Größe des Stacks (für Autodaten) der Threads fest, die
    Client-Verbindungen bearbeiten und Module aufrufen, welche bei der
    Verarbeitung dieser Verbindungen helfen. In den meisten Fällen ist die
    Voreinstellung des Betriebssystems angemessen, doch unter bestimmten
    Umständen kann es sinnvoll sein, den Wert anzupassen:
    

    
      
      
    • Auf Plattformen mit einer relativ kleinen Voreingestellung für
      die Größe des Thread-Stacks (z.B. HP-UX) kann der Apache bei
      der Verwendung einiger Drittanbietermodule, die einen relativ hohen Bedarf
      an Speicherplatz haben, abstürzen. Ebendiese Module arbeiten
      möglicherweise problemlos auf anderen Plattformen, wo der
      voreingestellte Thread-Stack größer ist. Derartige
      Abstürze können Sie vermeiden, indem Sie
      ThreadStackSize auf einen höheren Wert als die
      Betriebssystemvoreinstellung setzen.  Eine solche Anpassung ist nur
      notwendig, wenn es vom Anbieter des Moduls so spezifiziert wurde oder die
      Diagnose eines Apache-Absturzes ergeben hat, das die
      Thread-Stackgröße zu klein war.
      • 

      
    • Auf Plattformen, wo die voreingestellte Thread-Stackgröße
      für die Webserverkonfiguration deutlich größer als
      notwendig ist, kann eine größere Anzahl von Threads pro
      Kindprozess erreicht werden, wenn ThreadStackSize
      auf einen Wert kleiner als die Betriebssystemvoreinstellung gesetzt wird.
      Da es einzelne Anfragen geben kann, die mehr Stack zur Verarbeitung
      benötigen, sollte eine derartige Korrektur ausschließlich in
      Testumgebungen zum Einsatz kommen, auf denen die gesamte
      Webserververarbeitung ausprobiert werden kann. Eine Änderung der
      Webserverkonfiguration kann den aktuellen Wert der
      ThreadStackSize ungültig machen.

    Summary
    

    
    This module queries an RFC 1413 compatible daemon on a remote host to look up the owner of
    a connection.

    Module:mod_ident
    

    Compatibility:Moved out of core in Apache 2.1
    

    
    
    This directive enables RFC 1413-compliant logging of the remote user name for each
    connection, where the client machine runs identd or something similar.
    This information is logged in the access log using the %...l
    format string.
    

    
    
      The information should not be trusted in any way except for
      rudimentary usage tracking.
    
    

    
    Note that this can cause serious latency problems accessing
    your server since every request requires one of these lookups
    to be performed. When firewalls or proxy servers are involved,
    each lookup might possibly fail and add a latency duration as
    defined by the IdentityCheckTimeout directive to each hit. So in
    general this is not very useful on public servers accessible from
    the Internet.

    Status:Extension
    

    Module:mod_ident
    

    
    
    This directive specifies the timeout duration of an ident
    request. The default value of 30 seconds is recommended by RFC 1413, mainly because
    of possible network latency. However, you may want to adjust the
    timeout value according to your local network speed.

    Apache Module mod_mime_magic

    Description:Determines the MIME type of a file
    by looking at a few bytes of its contents
    

    Status:Extension
    

    Module Identifier:mime_magic_module
    

    Source File:mod_mime_magic.c
    

    Summary
    

    
    This module determines the MIME
    type of files in the same way the Unix
    file(1) command works: it looks at the first few
    bytes of the file. It is intended as a "second line of defense"
    for cases that mod_mime can't resolve.
    

    
    This module is derived from a free version of the
    file(1) command for Unix, which uses "magic
    numbers" and other hints from a file's contents to figure out
    what the contents are. This module is active only if the magic
    file is specified by the MimeMagicFile directive.
    

    


    top
    

    

    Format of the Magic File
    

    
    The contents of the file are plain ASCII text in 4-5
    columns. Blank lines are allowed but ignored. Commented lines
    use a hash mark (#). The remaining lines are parsed for
    the following columns:

        MIME encoding if matched (optional)
    

    

    
    For example, the following magic file lines would recognize
    some audio formats:
    

    
    # Sun/NeXT audio data
0      string      .snd
>12    belong      1       audio/basic
>12    belong      2       audio/basic
>12    belong      3       audio/basic
>12    belong      4       audio/basic
>12    belong      5       audio/basic
>12    belong      6       audio/basic
>12    belong      7       audio/basic
>12    belong     23       audio/x-adpcm
    

    
    Or these would recognize the difference between *.doc
    files containing Microsoft Word or FrameMaker documents. (These are
    incompatible file formats which use the same file suffix.)
    

    
    # Frame
0  string  \<MakerFile        application/x-frame
0  string  \<MIFFile          application/x-frame
0  string  \<MakerDictionary  application/x-frame
0  string  \<MakerScreenFon   application/x-frame
0  string  \<MML              application/x-frame
0  string  \<Book             application/x-frame
0  string  \<Maker            application/x-frame

# MS-Word
0  string  \376\067\0\043            application/msword
0  string  \320\317\021\340\241\261  application/msword
0  string  \333\245-\0\0\0           application/msword
    

    
    An optional MIME encoding can be included as a fifth column.
    For example, this can recognize gzipped files and set the
    encoding for them.
    

    
    # gzip (GNU zip, not to be confused with
#       [Info-ZIP/PKWARE] zip archiver)

0  string  \037\213  application/octet-stream  x-gzip

    Performance Issues
    
    
    This module is not for every system. If your system is barely
    keeping up with its load or if you're performing a web server
    benchmark, you may not want to enable this because the
    processing is not free.
    

    
    However, an effort was made to improve the performance of
    the original file(1) code to make it fit in a busy web
    server. It was designed for a server where there are thousands of users
    who publish their own documents. This is probably very common
    on intranets. Many times, it's helpful if the server can make
    more intelligent decisions about a file's contents than the
    file name allows ...even if just to reduce the "why doesn't my
    page work" calls when users improperly name their own files.
    You have to decide if the extra work suits your
    environment.

mod_setenvif - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Apache Module mod_setenvif
    

    

    Available Languages:  en  |

    Description:Allows the setting of environment variables based
on characteristics of the request
    

    Status:Base
    

    Module Identifier:setenvif_module
    

    Source File:mod_setenvif.c
    

    Summary
    


    
    The mod_setenvif module allows you to set
    internal environment variables according to whether different aspects of
    the request match regular expressions you specify. These
    environment variables can be used by other parts of the server
    to make decisions about actions to be taken, as well as becoming
    available to CGI scripts and SSI pages.
    

    
    The directives are considered in the order they appear in
    the configuration files. So more complex sequences can be used,
    such as this example, which sets netscape if the
    browser is mozilla but not MSIE.
    


    BrowserMatch ^Mozilla netscape
BrowserMatch MSIE !netscape
    


   
    When the server looks up a path via an internal 
   subrequest such as looking 
   for a DirectoryIndex 
   or generating a directory listing with mod_autoindex,
   per-request environment variables are not inherited in the 
   subrequest. Additionally, 
   SetEnvIf directives
   are not separately evaluated in the subrequest due to the API phases
   mod_setenvif takes action in.

    BrowserMatch Directive
    

    

    Description:Sets environment variables conditional on HTTP User-Agent

    

    Syntax:BrowserMatch regex [!]env-variable[=value]
[[!]env-variable[=value]] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_setenvif
    

    
  
    The BrowserMatch is a special cases of the
  SetEnvIf directive that
  sets environment variables conditional on the
  User-Agent HTTP request header.  The following two
  lines have the same effect:
    

    BrowserMatch Robot is_a_robot
SetEnvIf User-Agent Robot is_a_robot
    


    
    Some additional examples:
    

    BrowserMatch ^Mozilla forms jpeg=yes browser=netscape
BrowserMatch "^Mozilla/[2-3]" tables agif frames javascript
BrowserMatch MSIE !javascript

    BrowserMatchNoCase Directive
    

    

    Description:Sets environment variables conditional on User-Agent without
respect to case
    

    Syntax:BrowserMatchNoCase  regex [!]env-variable[=value]
    [[!]env-variable[=value]] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_setenvif
    

    

    
    The BrowserMatchNoCase directive is
    semantically identical to the BrowserMatch directive.
    However, it provides for case-insensitive matching. For
    example:
    

    BrowserMatchNoCase mac platform=macintosh
BrowserMatchNoCase win platform=windows
    


    
    The BrowserMatch and
    BrowserMatchNoCase directives are special cases of
    the SetEnvIf and SetEnvIfNoCase
    directives. The following two lines have the same effect:
    

    BrowserMatchNoCase Robot is_a_robot
SetEnvIfNoCase User-Agent Robot is_a_robot

    SetEnvIf Directive
    

    

    Description:Sets environment variables based on attributes of the request

    

    Syntax:SetEnvIf attribute
    regex [!]env-variable[=value]
    [[!]env-variable[=value]] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_setenvif
    

    
    
    The SetEnvIf directive defines
    environment variables based on attributes of the request. The
    attribute specified in the first argument can be one of four
    things:
    


      

    1. An HTTP request header field (see RFC2616
    for more information about these); for example: Host,
    User-Agent, Referer, and
    Accept-Language.  A regular expression may be
    used to specify a set of request headers.
      2. 


    2. One of the following aspects of the request:
    
        
      
      • Remote_Host - the hostname (if available) of
      the client making the request
        • 

      
      • Remote_Addr - the IP address of the client
      making the request
        • 

      
      • Server_Addr - the IP address of the server
      on which the request was received (only with versions later
      than 2.0.43)
        • 

      
      • Request_Method - the name of the method
      being used (GET, POST, et
      cetera)
        • 

      
      • Request_Protocol - the name and version of
      the protocol with which the request was made (e.g.,
      "HTTP/0.9", "HTTP/1.1", etc.)
        • 

      
      • Request_URI - the resource requested on the HTTP
       request line -- generally the portion of the URL
      following the scheme and host portion without the query string. See
      the RewriteCond
      directive of mod_rewrite for extra information on
      how to match your query string.
        • 
    
      

      3. 


    3. The name of an environment variable in the list of those
associated with the request. This allows
SetEnvIf directives to test against the result
of prior matches. Only those environment variables defined by earlier
SetEnvIf[NoCase] directives are available for testing in
this manner. 'Earlier' means that they were defined at a broader scope
(such as server-wide) or previously in the current directive's scope.
Environment variables will be considered only if there was no match
among request characteristics and a regular expression was not
used for the attribute.
      4. 


    


    The second argument (regex) is a regular expression.  If the regex
matches against the attribute, then the remainder of the
arguments are evaluated.
    


    The rest of the arguments give the names of variables to set, and
optionally values to which they should be set. These take the form
of
    

    
      
      
    1. varname, or
      2. 

      
    2. !varname, or
      3. 

      
    3. varname=value
      4. 
    
    

    
    In the first form, the value will be set to "1". The second
    will remove the given variable if already defined, and the
    third will set the variable to the literal value given by
    value. Since version 2.0.51, Apache httpd will
    recognize occurrences of $1..$9 within
    value and replace them by parenthesized subexpressions
    of regex. $0 provides access to the whole
    string matched by that pattern.
    


    SetEnvIf Request_URI "\.gif$" object_is_image=gif
SetEnvIf Request_URI "\.jpg$" object_is_image=jpg
SetEnvIf Request_URI "\.xbm$" object_is_image=xbm
    
SetEnvIf Referer www\.mydomain\.example\.com intra_site_referral
    
SetEnvIf object_is_image xbm XBIT_PROCESSING=1
    
SetEnvIf Request_URI "\.(.*)$" EXTENSION=$1

SetEnvIf ^TS  ^[a-z]  HAVE_TS
    


    
    The first three will set the environment variable
    object_is_image if the request was for an image
    file, and the fourth sets intra_site_referral if
    the referring page was somewhere on the
    www.mydomain.example.com Web site.
    

    
    The last example will set environment variable
    HAVE_TS if the request contains any headers that
    begin with "TS" whose values begins with any character in the
    set [a-z].

    SetEnvIfExpr Directive
    

    

    Description:Sets environment variables based on an ap_expr expression
    

    Syntax:SetEnvIfExpr expr
    [!]env-variable[=value]
    [[!]env-variable[=value]] ...
    

    Context:server config, virtual host, directory, .htaccess
    

    Override:FileInfo
    

    Status:Base
    

    Module:mod_setenvif
    

    
    
    The SetEnvIfExpr directive defines
    environment variables based on an <If>
    ap_expr. These expressions will be evaluated at runtime,
    and applied env-variable in the same fashion as SetEnvIf.
    


    SetEnvIfExpr "tolower(req('X-Sendfile')) == 'd:\images\very_big.iso')" iso_delivered
    


    
    This would set the environment variable iso_delivered
    every time our application attempts to send it via X-Sendfile
    

    
    A more useful example would be to set the variable rfc1918 if the
    remote IP address is a private address according to RFC 1918:
    


    SetEnvIfExpr "-R '10.0.0.0/8' || -R '172.16.0.0/12' || -R '192.168.0.0/16'" rfc1918

    SetEnvIfNoCase Directive
    

    

    Description:Sets environment variables based on attributes of the request
without respect to case

    Status:Base
    

    Module:mod_setenvif
    

    

    
    The SetEnvIfNoCase is semantically identical to
    the SetEnvIf directive,
    and differs only in that the regular expression matching is
    performed in a case-insensitive manner. For example:
    

    SetEnvIfNoCase Host Example\.Org site=example
    


    
    This will cause the site environment variable
    to be set to "example" if the HTTP request header
    field Host: was included and contained
    Example.Org, example.org, or any other
    combination.

    Description:Dynamic health check of Balancer members (workers) for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_hcheck_module
    

    Source File:mod_proxy_hcheck.c
    

    Compatibility:Available in Apache 2.4.21 and later
    

    Summary
    

    
    This module provides for dynamic health checking of balancer
    	members (workers). This can be enabled on a worker-by-worker
    	basis. The health check is done independently of the
    	actual reverse proxy requests.
    

    
    This module requires the service of mod_watchdog.
    


    Parameters
    
  
    The health check mechanism is enabled via the use of additional
     BalancerMember parameters, which are configured
     in the standard way via ProxyPass:
    

  
    A new BalancerMember status state (flag)
     is defined via this module: "C".
     When the worker is taken offline due to failures as determined by the health
     check module, this flag is set, and can be seen (and modified) via the
     balancer-manager.

        Name of expression, created via ProxyHCExpr,
            used to check response headers for health.
    
            If not used, 2xx thru 3xx status codes imply success
    
    
    

    


    


    top
    

    

    Usage examples
    

	
    
    The following example shows how one might configured health checking
    	for various backend servers:
    

	
	
    ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyHCExpr gdown {%{REQUEST_STATUS} =~ /^[5]/}
ProxyHCExpr in_maint {hc('body') !~ /Under maintenance/}

<Proxy balancer://foo>
  BalancerMember http://www.example.com/  hcmethod=GET hcexpr=in_maint hcuri=/status.php
  BalancerMember http://www2.example.com/ hcmethod=HEAD hcexpr=ok234 hcinterval=10
  BalancerMember http://www3.example.com/ hcmethod=TCP hcinterval=5 hcpasses=2 hcfails=3
  BalancerMember http://www4.example.com/
</Proxy>

ProxyPass "/" "balancer://foo"
ProxyPassReverse "/" "balancer://foo"
    



    In this scenario, http://www.example.com/ is health checked by sending a GET /status.php
request to that server and seeing that the returned page does not include the string Under maintenance. If
it does, that server is put in health-check fail mode, and disabled. This dynamic check is performed
every 30 seconds, which is the default.
    


    http://www2.example.com/ is checked by sending a simple HEAD request every
10 seconds and making sure that the response status is 2xx, 3xx or 4xx. http://www3.example.com/ is checked
every 5 seconds by simply ensuring that the socket to that server is up. If the backend is marked as
"down" and it passes 2 health check, it will be re-enabled and added back into the load balancer.
It takes 3 back-to-back health check failures to disable the server and move it out
of rotation. Finally, http://www4.example.com/ is
not dynamically checked at all.

    ProxyHCExpr Directive
    

    

    Description:Creates a named condition expression to use to determine health of the backend based on its response
    

    Syntax:ProxyHCExpr name {ap_expr expression}
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy_hcheck
    

    
    
    The ProxyHCExpr directive allows
       for creating a named condition expression that checks the response
       headers of the backend server to determine its health. This named
       condition can then be assigned to balancer members via the hcexpr
       parameter.
    

    
    ProxyHCExpr: Allow for 2xx/3xx/4xx as passing
    ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyPass "/apps"     "balancer://foo"

<Proxy balancer://foo>
  BalancerMember http://www2.example.com/  hcmethod=HEAD hcexpr=ok234 hcinterval=10
</Proxy>
    

    

    
    
    The expression can use curly-parens ("{}") as
    quoting deliminators in addition to normal quotes.
    
    

    
    If using a health check method (eg: GET) which results in a response
    body, that body itself can be checked via ap_expr using the hc()
    expression function, which is unique to this module.
    

    
    In the following example, we send the backend a GET request
    and if the response body contains the phrase Under maintenance,
    we want to disable the backend.
    

    
    ProxyHCExpr: Checking response body
    ProxyHCExpr in_maint {hc('body') !~ /Under maintenance/}
ProxyPass "/apps"     "balancer://foo"

<Proxy balancer://foo>
  BalancerMember http://www.example.com/ hcexpr=in_maint hcmethod=get hcuri=/status.php
</Proxy>
    

    

    
    NOTE: Since response body can quite large, it is best if used against specific status pages.

    ProxyHCTemplate Directive
    

    

    Description:Creates a named template for setting various health check parameters
    

    Syntax:ProxyHCTemplate name parameter=setting [...]
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_proxy_hcheck
    

    
    
    The ProxyHCTemplate directive allows
       for creating a named set (template) of health check parameters
       that can then be assigned to balancer members via the hctemplate
       parameter.
    

    
    ProxyHCTemplate
    ProxyHCTemplate tcp5 hcmethod=tcp hcinterval=5
ProxyPass "/apps"     "balancer://foo"

<Proxy balancer://foo>
  BalancerMember http://www2.example.com/ hctemplate=tcp5
</Proxy>

    ProxyHCTPsize Directive
    

    

    Description:Sets the total server-wide size of the threadpool used for the health check workers
    

    Syntax:ProxyHCTPsize size
    

    Default:ProxyHCTPsize 16
    

    Context:server config
    

    Status:Extension
    

    Module:mod_proxy_hcheck
    

    
    
    If Apache httpd and APR are built with thread support, the health check
       module will offload the work of the actual checking to a threadpool
       associated with the Watchdog process, allowing for parallel checks.
       The ProxyHCTPsize directive
       determines the size of this threadpool. If set to 0, no threadpool
       is used at all, resulting in serialized health checks.
    

    
    ProxyHCTPsize
    ProxyHCTPsize 32

    Apache Module mod_proxy_ftp
    

    

    Available Languages:  en  |

    Description:FTP support module for
mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_ftp_module
    

    Source File:mod_proxy_ftp.c
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the proxying
    FTP sites.  Note that FTP support is currently limited to
    the GET method.
    

    
    Thus, in order to get the ability of handling FTP proxy requests,
    mod_proxy and mod_proxy_ftp
    have to be present in the server.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.

    Why doesn't file type xxx
    download via FTP?
    
      
    You probably don't have that particular file type defined as
      application/octet-stream in your proxy's mime.types
      configuration file. A useful line can be:
    

      
    application/octet-stream   bin dms lha lzh exe class tgz taz
    
      
    Alternatively you may prefer to use the ForceType
      directive to default everything to binary:
    
      
    ForceType application/octet-stream
    

    
    
    top
    

    

    How can I force an FTP ASCII download of
    file xxx?
    
      
    In the rare situation where you must download a specific file using the
      FTP ASCII transfer method (while the default transfer is in
      binary mode), you can override mod_proxy's
      default by suffixing the request with ;type=a to force an
      ASCII transfer. (FTP Directory listings are always executed in ASCII mode,
      however.)
    
    
    top
    

    

    How can I do FTP upload?
    
    
    Currently, only GET is supported for FTP in mod_proxy.  You can
    of course use HTTP upload (POST or PUT) through an Apache proxy.
    
    
    top
    

    

    How can I access FTP files outside
    of my home directory?
    
      
    An FTP URI is interpreted relative to the home directory of the user
      who is logging in. Alas, to reach higher directory levels you cannot
      use /../, as the dots are interpreted by the browser and not actually
      sent to the FTP server. To address this problem, the so called Squid
      %2f hack was implemented in the Apache FTP proxy; it is a
      solution which is also used by other popular proxy servers like the Squid Proxy Cache. By
      prepending /%2f to the path of your request, you can make
      such a proxy change the FTP starting directory to / (instead
      of the home directory). For example, to retrieve the file
      /etc/motd, you would use the URL:
    

      
    
        ftp://user@host/%2f/etc/motd
      
    
    
    top
    

    

    How can I hide the FTP cleartext password
    in my browser's URL line?
    
      
    To log in to an FTP server by username and password, Apache uses
      different strategies. In absence of a user name and password in the URL
      altogether, Apache sends an anonymous login to the FTP server,
      i.e.,
    

      
    
        user: anonymous
    
        password: apache-proxy@
      
    

      
    This works for all popular FTP servers which are configured for
      anonymous access.
    

      
    For a personal login with a specific username, you can embed the user
      name into the URL, like in:
    

      
    
        ftp://username@host/myfile
      
    

      
    If the FTP server asks for a password when given this username (which
      it should), then Apache will reply with a 401 (Authorization
      required) response, which causes the Browser to pop up the
      username/password dialog. Upon entering the password, the connection
      attempt is retried, and if successful, the requested resource is
      presented. The advantage of this procedure is that your browser does not
      display the password in cleartext (which it would if you had used
    

      
    
        ftp://username:password@host/myfile
      
    

      
    in the first place).
    

      
    Note
    
        
    The password which is transmitted in such a way is not encrypted on
        its way. It travels between your browser and the Apache proxy server in
        a base64-encoded cleartext string, and between the Apache proxy and the
        FTP server as plaintext. You should therefore think twice before
        accessing your FTP server via HTTP (or before accessing your personal
        files via FTP at all!) When using insecure channels, an eavesdropper
        might intercept your password on its way.
    
      
    
    
    top
    

    

    Why do I get a file listing when I expected
        a file to be downloaded?
    
      
    In order to allow both browsing the directories on an FTP server and
        downloading files, Apache looks at the request URL.  If it looks like
        a directory, or contains wildcard characters ("*?[{~"), then it
        guesses that a listing is wanted instead of a download.
    
      
    You can disable the special handling of names with wildcard characters.
        See the ProxyFtpListOnWildcard directive.

    ProxyFtpEscapeWildcards Directive

    The ProxyFtpEscapeWildcards directive
    controls whether wildcard characters ("*?[{~") in requested
    filenames are escaped with backslash before sending them to the
    FTP server.  That is the default behavior, but many FTP servers
    don't know about the escaping and try to serve the literal filenames
    they were sent, including the backslashes in the names.
    
    
    Set to "off" to allow downloading files with wildcards
    in their names from FTP servers that don't understand wildcard
    escaping.

    The ProxyFtpListOnWildcard directive
    controls whether wildcard characters ("*?[{~") in requested
    filenames cause mod_proxy_ftp to return a listing
    of files instead of downloading a file.  By default (value on),
    they do.
    
    
    Set to "off" to allow downloading files even if they
    have wildcard characters in their names.

    Description:Répertoires propres à un utilisateur

    Fichier Source:mod_userdir.c
    

    Sommaire
    


    En activant ce module, vous permettez à plusieurs
utilisateurs de stocker des contenus sous un seul noeud de l'arborescence. La
politique de stockage sous un seul noeud de l'arborescence est un principe clé de
Javascript et de la sécurité du web. En stockant des pages web sous un seul noeud
de l'arborescence, celles-ci peuvent se lire et se contrôler mutuellement et
d'éventuels problèmes de sécurité liés à une page peut affecter les autres. Ceci
peut s'avérer particulièrement dangereux dans le cas des pages web mettant en
oeuvre du contenu dynamique et de l'authentification et lorsque les utilisateurs
ne se voient pas tous forcément d'un bon oeil.
    


    Ce module permet l'accès aux répertoires propres à un utilisateur en
utilisant la syntaxe http://example.com/~utilisateur/.

    Directive UserDir
    

    

    Description:Chemin des répertoires propres à un
utilisateur
    

    Syntaxe:UserDir nom-répertoire [nom-répertoire] ...

    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Base
    

    Module:mod_userdir
    

    

    
    La directive UserDir permet de définir le
    répertoire réel du répertoire home d'un utilisateur à utiliser à la
    réception d'une requête pour un document de cet utilisateur.
    nom-répertoire peut se présenter sous la forme suivante
    :
    

    
      
      
    • Le nom d'un répertoire ou un modèle tel que ceux présentés
      ci-dessous.
      • 

      
    • Le mot-clé disabled. Toutes les
      traductions nom d'utilisateur vers répertoire sont alors
      désactivées, à l'exception de celles comportant le mot-clé
      enabled (voir ci-dessous).
      • 

      
    • Le mot-clé disabled suivi d'une liste de noms
      d'utilisateurs séparés par des espaces. Les noms d'utilisateurs
      apparaissant dans une telle liste ne feront jamais
      l'objet d'une traduction vers un répertoire, même dans le cas où
      ils apparaîtront dans une clause enabled.
      • 

      
    • Le mot-clé enabled suivi d'une liste de noms
      d'utilisateurs séparés par des espaces. Les noms d'utilisateurs
      apparaissant dans une telle liste seront traduits en répertoires
      même dans le cas où une clause disable globale est active, mais
      pas s'ils apparaissent aussi dans une clause
      disabled.
      • 
    
    

    
    Si aucun mot-clé enabled ou disabled
    n'apparait dans la directive Userdir, l'argument est
    traité en tant que modèle de fichier, et utilisé pour traduire le
    nom d'utilisateur en une spécification de répertoire. Une requête
    pour http://www.example.com/~bob/un/deux.html sera
    traduite en :
    

    
    
      
    Directive Userdir utilisée
          Chemin traduit
    
      
    UserDir public_html
          ~bob/public_html/un/deux.html
    
      
    UserDir /usr/web
          /usr/web/bob/un/deux.html
    
      
    UserDir /home/*/www
          /home/bob/www/un/deux.html
    
    
    

    
    Les directives suivantes vont envoyer des redirections au client
    :
    

    
    
      
    Directive Userdir utilisée
          Chemin traduit
    
      
    UserDir http://www.example.com/utilisateurs
          http://www.example.com/utilisateurs/bob/un/deux.html
    
      
    UserDir http://www.example.com/*/usr
          http://www.example.com/bob/usr/un/deux.html
    
      
    UserDir http://www.example.com/~*/
          http://www.example.com/~bob/un/deux.html
    
    
    

    
    
      Soyez prudent avec cette directive ; par exemple,
      "UserDir ./" ferait correspondre
      "/~root" à "/" - ce qui n'est
      probablement pas souhaité. Il est fortement recommandé d'inclure
      une déclaration "UserDir disabled root" dans votre
      configuration. Voir aussi la directive Directory et la page Conseils en matière de
      sécurité pour plus d'informations.
    
    

    
    Exemples supplémentaires :
    

    
    Pour permettre à quelques utilisateurs et seulement à ceux-ci de
    posséder des répertoires UserDir, utilisez la
    configuration suivante :
    

    
    UserDir disabled
UserDir enabled user1 user2 user3
    


    
    Pour permettre à la plupart des utilisateurs de posséder des
    répertoires UserDir, mais l'interdire à quelques uns,
    utilisez la configuration suivante :
    

    
    UserDir disabled utilisateur4 utilisateur5 utilisateur6
    


    
    Il est aussi possible de spécifier des répertoires utilisateurs
    alternatifs. Si vous utilisez une commande comme :
    

    
    UserDir "public_html" "/usr/web" "http://www.example.com/"
    


    
    Avec une requête pour
    http://www.example.com/~bob/un/deux.html, le serveur
    tentera tout d'abord de trouver la page à
    ~bob/public_html/un/deux.html, puis à
    /usr/web/bob/un/deux.html, et enfin il enverra une
    redirection vers
    http://www.example.com/bob/un/deux.html.
    

    
    Si vous spécifiez une redirection, elle doit être la dernière
    alternative de la liste. Apache httpd ne pouvant pas déterminer si la
    redirection a réussi, si cette dernière ne se trouve pas en fin de
    liste, c'est cette alternative qui sera toujours utilisée.
    

    
    La substitution de répertoire utilisateur n'est pas activée par
    défaut depuis la version 2.1.4. Dans les versions précédentes,
    UserDir public_html était sous-entendu si aucune
    directive UserDir
    n'était présente.
    

    
    Détails à propos de la fusion
    
    
    Lorsqu'on passe du contexte global au contexte de serveur
    virtuel, les listes d'utilisateurs spécifiques activés ou désactivés
    sont remplacées par les listes du contexte, et non fusionnées.

    この日本語訳はすでに古くなっている

            最近更新された内容を見るには英語版をご覧下さい。
        
    

    説明:HTTP リクエストのヘッダと応答のヘッダのカスタマイズ
    

    ステータス:Extension
    

    モジュール識別子:headers_module
    

    ソースファイル:mod_headers.c
    

    互換性:RequestHeader 
は Apache 2.0 以降のみで使用可能
    

    概要
    

    
    このモジュールは HTTP のリクエストヘッダと応答ヘッダを制御し、
    変更するためのディレクティブを提供します。ヘッダを追加したり、
    置き換えたり、削除したりすることができます。
    

    


    top
    

    

    処理の順番
    

    
    mod_headers のディレクティブはサーバ設定のほぼどこにでも
    書くことができ、影響する範囲を設定用セクションで囲むことで限定する
    ことができます。
    

    
    処理の順番は重要で、設定ファイル中の順番と、設定用セクション内の位置との両方に
    影響されます。以下の二つのヘッダは順番が逆になると
    違う結果になります:
    

    
    
      RequestHeader append MirrorID "mirror 12"
    
      RequestHeader unset MirrorID
    
    

    
    この順番の場合は、MirrorID ヘッダは設定されません。
    逆になっていると、MirrorID ヘッダは "mirror 12" に設定されます。
    

    top
    

    

    早期処理、後期処理
    
    
    mod_headers では、リクエストの早期か後期かの
    どちらで適用するかを選べます。通常は後期モードで、
    コンテンツ生成が実行される直前にリクエストヘッダがセットされ、
    レスポンスとして送出される直前にレスポンスヘッダがセットされます。
    運用中のサーバでは必ず後期モードを使ってください。
    

    
    早期モードは開発者向けのテスト/デバッグ用に設計されています。
    early キーワード指定されたディレクティブによって、
    リクエスト処理の開始地点になります。
    つまり、異なるリクエストを試したりテストケースをセットアップするのに
    活用できる一方で、レスポンスを生成する前に他のモジュールによって
    ヘッダが書き換えられてしまうかもしれないということを意味します。
    

    
    early ディレクティブではリクエストパスの設定が解決される前に
    処理されるので、メインサーバかバーチャルホストコンテキストでのみ、
    早期ヘッダをセットできます。early ディレクティブはリクエストパスに
    依存することはできませんので、<Directory> や
    <Location> といったコンテキスト内では使用
    できません。
    

    top
    

    

    例
    

    
      
      
    1. リクエストヘッダ中の "TS" で始まるフィールドをすべて応答ヘッダに
        コピーします:
        
      
          Header echo ^TS
        
      
      
      2. 

      
    2. 
        リクエストを受け付けた時刻とリクエストを処理した時間を入れたヘッダ、
        MyHeader を応答に追加します。このヘッダはクライアントが
        サーバの負荷を直観的に知るためや、クライアント-サーバ間の
        ボトルネックを調べるために使うことができます。

        
      
           Header add MyHeader "%D %t"
        
      

        
      上記の設定では、以下のようなヘッダが応答に追加されることになります:
      

        
      
           MyHeader: D=3775428 t=991424704447256
        
      
      
      3. 

      
    3. 
        Joe にあいさつをします:

        
      
           Header add MyHeader "Hello Joe. It took %D microseconds for Apache to serve this request."
        
      

        
      以下のようなヘッダが応答に追加されることになります
      

        
      
           MyHeader: Hello Joe. It took D=3775428 microseconds for Apache to serve this request.
        
      
      
      4. 

      
    4. リクエストに "MyRequestHeader" があるときに限り MyHeader を応答に
      付けます。これは、クライアントの要求に応えてヘッダを作成するときに
      役に立ちます。この例では mod_setenvif モジュールが必要なことに
      注意してください。

        
      
           SetEnvIf MyRequestHeader value HAVE_MyRequestHeader
      
           Header add MyHeader "%D %t mytext" env=HAVE_MyRequestHeader
        
      

        
      もし HTTP リクエストに MyRequestHeader: value ヘッダが
        あると、応答には以下のようなヘッダが付加されます。
      

        
      
           MyHeader: D=3775428 t=991424704447256 mytext
        
      
      
      5. 
    
    

    

    top
    

    Header ディレクティブ
    

    

    説明:HTTP 応答ヘッダの設定
    

    構文:Header [condition] set|append|add|unset|echo
header [value] [early|env=[!]variable]
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト, ディレクトリ, .htaccess
    

    上書き:FileInfo
    

    ステータス:Extension
    

    モジュール:mod_headers
    

    
    
    このディレクティブは HTTP 応答ヘッダを置換、追加、削除できます。
    ヘッダはコンテントハンドラや出力フィルタが実行された直後に実行され、
    出て行くヘッダを変更できるようになっています。
    

    
    オプションの condition は onsuccess か
    always のどちらかを指定できます。これは内部ヘッダテーブルのどれを
    操作するかを決定します。onsuccess は 2xx
    ステータスコードの、always は全てのステータスコード
    (2xx を含む) の意味になります。
    あるモジュールでセットされるヘッダをアンセットしたい場合は特に、
    どのテーブルが影響を受けるかを実際に試したほうがよいでしょう。
    

    
    行なう処理は二番目のの引数で決まります。
    この引数には次の値を指定できます:
    

    
    
    
    set
    
    
    応答ヘッダを設定します。同じ名前のヘッダが存在する場合はそれを
    置き換えます。value にはフォーマット文字列を
    指定することもできます。
    

    
    append
    
    
    応答ヘッダを既に存在する同じ名前のヘッダに追加します。
    新しい値が既存のヘッダに追加されるときには、既存のヘッダの
    後にコンマで区切られて追加されます。これはヘッダに複数の値を
    指定するときの HTTP の標準の方法です。
    

    
    add
    
    
    ヘッダが既に存在しているときでさえも、応答ヘッダを
    既存のヘッダに追加します。これにより、二つ (かそれ以上) の
    ヘッダの名前が同じになることがあります。その結果、想定できない
    ことが起こる可能性がありますので、一般的には append の方を
    使う方が良いでしょう。
    

    
    unset
    
    
    もし指定された名前の応答ヘッダが存在していれば、削除されます。
    同じ名前のヘッダが複数あるときは、すべて削除されます。
    value をつけてはいけません。
    

    
    echo
    
    
    指定されたものと同じ名前のリクエストヘッダを応答ヘッダで
    そのまま返します。header には正規表現も指定できます。
    value をつけてはいけません。
    
    
    

    
    この引数の後にはヘッダ名 (header) が続きます。
    ヘッダ名には最後にコロンを含めることもできますが、無くても構いません。
    set, append, add,
    unset では大文字小文字は
    区別されません。echo の header 名は大文字小文字を区別し、
    正規表現を指定することもできます。
    

    
    add, append,
    set では value を三つ目の
    引数として指定します。value に空白がある場合は二重引用符で
    囲む必要があります。value は文字のみからなる文字列、
    フォーマット指示子を含む文字列、もしくは両方からなる文字列を指定できます。
    value は以下のフォーマット指示子をサポートします:
    

    
    フォーマット解説
    

    %%
        パーセント記号
    

    %t
        リクエストを受け取った時刻を、
        Universal Coordinated Time での始まりの時刻 (Jan. 1, 1970) から経過した
        時間をマイクロ秒として現したもの。値の最初には 
        t= が付加されます。
    

    %D
        リクエストを受け取った時刻と、ヘッダを送り出した
        時間との差。これは、リクエストが存在していた期間を現します。
        値の最初には D= が付加されます。
    

    %{FOOBAR}e
        環境変数
        FOOBAR の値です。
    

    %{FOOBAR}s
        mod_ssl が有効な場合、
        SSL 環境変数 FOOBAR
        の内容
    

    

    
    注
    
      
    %s フォーマット指定子は 2.1 以降でのみ利用できます。
      SSLOptions +StdEnvVars を有効にすることによるオーバーヘッドを
      避けるため、%e の代わりとして使えます。
      他の理由などがあって、どうしても SSLOptions +StdEnvVars 
      を有効にしなければならない場合は、%e のほうが
      %s よりも処理効率は良いです。
    
    
     

    
    Header ディレクティブには追加の引数を持たせることが
    できて、どういったアクションが行われたかの条件を指定したり、
    早期処理 を指定する early キーワードを
    指定できます。
    env=... 引数で指定された 環境変数 が存在する (もしくは env=!...
    が指定されていて環境変数が存在しない) 場合は、Header
    ディレクティブで指定された動作が行なわれます。そうでない場合は、
    ディレクティブはそのリクエストには何もしません。
    

    
    早期処理モードの場合以外では、
    Header
    ディレクティブは応答がネットワークに送られる直前に
    処理されます。これは、ヘッダフィルタにより追加されるヘッダを
    除き、ほとんどのヘッダを設定したり上書きしたりすることが
    可能、ということです。

    append, set の場合は、value が三つ目の
    引数として指定されます。value に空白がある場合は二重引用符で
    囲む必要があります。unset の場合は、value は指定しません。
    value は文字列、フォーマット指定子、あるいは、その混合です。
    使うことのできるフォーマット指定子は、Header と同じですので、
    詳細はそちらをご覧ください。
    

    
    RequestHeader ディレクティブは、
    どういった条件下でアクションを行うかを指定する追加引数
    あるいは、早期処理 を指定する early 
    キーワードを設定することができます。
    env=... の引数で設定されている
    環境変数 が存在している
    (あるいは env=!... で指定された環境変数が
    存在しない) 場合、RequestHeader ディレクティブは
    有効になります。それ以外の場合、ディレクティブは効力を持ちません。
    

    
    early モードでない場合に限り、
    RequestHeader ディレクティブは
    fixup フェーズでリクエストがハンドラに扱われる直前に
    処理されます。これにより、ブラウザや Apache の入力フィルタにより
    生成されたヘッダを上書きしたり修正したりできるようになっています。

    この文書は各 Apache 設定ディレクティブ
    を説明するために使われている用語を説明します。
    

    


    top
    

    

    説明
    


    ディレクティブの目的の簡単な説明。
    

    top
    

    

    構文
    

    
    設定ファイル中のディレクティブの書式を示します。
    この構文はディレクティブ特有なので、詳細はディレクティブの説明を
    参照してください。一般的に、ディレクティブ名の後には
    空白により分割されたいくつかの引数が続きます。
    引数が空白を含むときは二重引用符 (訳注: ")
    で囲まれています。 オプショナルな引数は括弧
    (訳注: []) で囲まれています。
    引数が複数の値を取り得る場合は、それらの値は垂直の棒 "|"
    で 分割されています。
    変更されないテキストはデフォルトのフォントで表示され、置換の必要な
    引数は強調されて表示されます。
    引数の数が変わるディレクティブは最後の
    引数が繰り返されることを示すために "..."
    で終わります。
    

    
    
    ディレクティブは多くの違う型の引数をとります。いくつか、良く
    使われるものを以下で定義します。
    

    
    
      
    URL
    

      
    http://www.example.com/path/to/file.html
      のように、
      スキーム、ホスト名、パス名(省略可能)を含んでいる完全な
      Uniform Resource Locator。
    

      
    URL-path
    

      
    /path/to/file.html のように、スキームと
      ホスト名の後に続く url
      の一部。url-path は
      ファイルシステムからの視点ではなく、
      ウェブからの視点でリソースを表現します。
    

      
    file-path
    

      
    /usr/local/apache/htdocs/path/to/file.html
      のように、
      ルートディレクトリから始まるローカルのファイルシステム上のファイルへのパス。
      通常、スラッシュで始まらない file-path は ServerRoot
      からの相対パスとして 扱われます。
    

      
    directory-path
    

      
    /usr/local/apache/htdocs/path/to/
      のように、
      ルートディレクトリから始まるローカルのファイルシステムのディレクトリへの
      パス。
    

      
    filename
    

      
    file.html のように、パス情報の付いていない
      ファイル名。
    

      
    regex
    

      
    Perl 互換の正規表現です。
      ディレクティブの定義が regex
      が何に対してマッチを行なうのかを指定します。
    

      
    extension
    

      
    一般的には filename
      の最後のドットの後の部分です。 しかし、Apache
      は複数のファイルの拡張子を認識しますので、filename
      に複数のドットがあると、最初のドットの後の、それぞれのドットで分離された部分が
      extension (訳注: 拡張子)
      になります。例えば、filename
      file.html.en
      には二つの拡張子があります。.html と
      .en です。Apache
      のディレクティブでは、extension
      はドット付きでも無しでも指定できます。さらに、extension
      は 大文字小文字を区別しません。
    

      
    MIME-type
    

      
    text/html のように、スラッシュで分離された
      主フォーマットと副フォーマットによってファイルの形式を
      表す方法です。
    

      
    env-variable
    

      
    Apache の設定により定義される 環境変数の名前です。これはオペレーティングシステムの
      環境変数と同じとは限らないことに注意してください。詳細は 環境変数の説明を参照してください。
    
    
    
  
    top
    

    

    デフォルト
    

    
    ディレクティブにデフォルト値
    (すなわち、設定ファイルから
    省略されていても、Apache
    ウェブサーバは特定の値に設定されているかのように
    動作します) がある場合はここに記述されます。
    デフォルト値の無い場合、ここは "None" と
    書かれます。ここで書かれているデフォルトはサーバと共に配布されている
    デフォルトの httpd.conf
    内に書かれているディレクティブの値と
    違う可能性があることに注意してください。
    

    top
    

    

    コンテキスト
    

    
    
    これは、サーバの設定ファイル中のどこでディレクティブが有効なのかを示します。
    次に示す値が一つ以上カンマ区切りで列挙されています。
    

    
    
      
    サーバ設定ファイル
    

      
    これは、サーバ設定ファイル
      (例えば、httpd.conf,
      srm.conf, access.conf)
      内では使用できますが、
      <VirtualHost> や
      <Directory> の中では
      使用できないことを示します。
      .htaccessファイルでの使用は許可されていません。
    

      
    バーチャルホスト
    

      
    これは、サーバ設定ファイルの
      <VirtualHost>
      の中で使用できることを示します。
    

      
    ディレクトリ
    

      
    これは、サーバ設定ファイルの
      <Directory>, 
      <Location>, 
      <Files>, 
      <If>, 
      <Proxy>
      コンテナの中で、 設定セクション
      で説明されている制限の下で使用できることを示します。
    

      
    .htaccess
    

      
    これは、ディレクトリ毎の
      .htaccess ファイル内で
      使用可能であることを示します。 ただ、上書き
      の設定によっては、処理されないかもしれません。
    
    
    

    
    
    ディレクティブは指示されたコンテキストでのみ許可されます。
    他の場所で使おうとすると、サーバがそのコンテキストを正しく扱えなく
    なるような設定エラーが発生するか、サーバがまったく動作しなくなる、
    すなわち、サーバが起動しなくなるということになります。
    

    
    
    ディレクティブの有効な位置は、実際は挙げられているコンテキストの
    論理和 (訳注: Boolen OR)
    になります。言い換えると、
    "サーバ設定ファイル、.htaccess" で有効だと
    記されているディレクティブは httpd.conf
    ファイルと .htaccess
    ファイルとで有効ですが、 <Directory>
    や <VirtualHost>
    の中では使用できません。
    

    top
    

    

    上書き
    

    
    このディレクティブの属性は、.htaccess
    ファイル中に
    ディレクティブが現れたときに、それの処理を有効にするために
    どの設定の上書きが必要かを示します。 ディレクティブの
    コンテキスト
    が、.htaccess
    ファイル中では許可していない場合は、 この属性は
    "適用不可" と書かれます。
    

    
    上書きは、AllowOverride
    ディレクティブによって有効にされ、
    特定のスコープ(ディレクトリなど)と、
    さらに下位のレベルの AllowOverride
    で修正されない限り、 その配下に対して適用されます。
    ディレクティブのドキュメントは取り得る上書きの名前も挙げます。
    

    top
    

    

    ステータス
    

    
    これはディレクティブが Apache
    ウェブサーバにどれくらいきつく組み込まれているかを
    示します。言い換えれば、ディレクティブとその機能を利用するために、
    モジュールの数を増やして、サーバを再コンパイルする必要があるかもしれない
    ということを示します。
    この属性が取り得る値は以下のものです:
    

    
    
      
    Core
    

      
    "Core" のディレクティブは Apache
      ウェブサーバの基本となるべきものであり、
      常に使用可能であることを示します。
    

      
    MPM
    

      
    "MPM" のディレクティブはマルチプロセッシングモジュールで提供されています。
      この種類のディレクティブはディレクティブの定義のモジュールの行に使っているモジュールの名前が書かれている
      場合にのみ使用可能です。
    

      
    Base
    

      
    "Base" のディレクティブは
      デフォルトでサーバに組み込まれている標準モジュールの中の一つでサ
      ポートされていて、わざわざ設定からモジュールを削除したときを除いて、
      通常では使用可能であることを示します。
    

      
    Extension
    

      
    "Extension" のディレクティブは、 Apache
      サーバの配布物に同梱されているモジュールの一つで提供されているものの、
      通常ではサーバに組み込まれていないことを示します。
      ディレクティブとその機能を有効にするには、サーバビルド用の設定ファイルを
      変更して Apache
      を再コンパイルする必要があります。
    

      
    Experimental
    

      
    "Experimental" のディレクティブは、Apache
      配布物に
      同梱されているものの、試したい場合は自己責任で行なう
      必要があるということを示します。ディレクティブは、すべてのドキュメントを
      完全にそろわせるために解説されていますが、サポートされているとは限りません。
      ディレクティブを提供するモジュールはデフォルトで組み込まれているかも
      しれませんし、そうでないかもしれません。使用可能かどうかは、
      ディレクティブとモジュールの説明をしているページの先頭を調べてください。

    Sommaire
    

    
    Ce module fournit la possibilité de mettre en tampon les piles
    des filtres en entrée et sortie.
    

    
    Dans certaines situations, les générateurs de contenu créent des
    contenus composés de petits tronçons. Afin de permettre la
    réutilisation de la mémoire, les éléments de mémoire attribués aux
    tronçons ont toujours une taille de 8k, quelle que soit la taille du
    tronçon lui-même. Lorsqu'une requête génère de nombreux petits
    tronçons, une grande quantité de mémoire peut être mobilisée par le
    traitement de la requête, et une grande quantité de données
    transmises sans nécessité. Pour y remédier, l'utilisation d'un
    tampon rassemble la réponse en un nombre de tronçons le plus petit
    possible.
    

    
    Lorsque httpd est utilisé comme frontal d'un générateur de
    contenu consommant beaucoup de ressources, la mise en tampon de la
    réponse peut permettre à ce dernier d'effectuer le traitement et de
    libérer les ressources plus ou moins rapidement, en fonction de la
    manière dont il a été conçu.
    

    
    Le filtre de mise en tampon peut être ajouté aux piles des
    filtres en entrée ou en sortie, selon les besoins, à l'aide des
    directives SetInputFilter,
    SetOutputFilter, AddOutputFilter ou AddOutputFilterByType.
    

      
    Utilisation d'un tampon avec mod_include
    AddOutputFilterByType INCLUDES;BUFFER text/html
    

    

    
    Les filtres de mise en tampon lisent la
    requête/réponse en RAM, puis la reconditionnent sous la forme d'un
    nombre d'éléments mémoire le plus petit possible, au prix d'une
    consommation de temps CPU. Lorsque la requête/réponse est déjà
    conditionnée de manière satisfaisante, sa mise en tampon pourrait
    s'avérer encore plus lente qu'en l'absence d'utilisation de tampon.
    C'est pourquoi ces filtres doivent être utilisés avec précautions,
    et seulement si nécessaire.

    Description:User-specific directories

    Module Identifier:userdir_module
    

    Source File:mod_userdir.c
    

    Summary
    


    By using this module you are allowing multiple users
to host content within the same origin. The same origin policy is a key
principle of Javascript and web security. By hosting web pages in the same
origin these pages can read and control each other and security issues in
one page may affect another. This is particularly dangerous in combination
with web pages involving dynamic content and authentication and when
your users don't necessarily trust each other.
    


    This module allows user-specific directories to be accessed using the
http://example.com/~user/ syntax.
    

    



    top
    

    UserDir Directive
    

    

    Description:Location of the user-specific directories
    

    Syntax:UserDir directory-filename [directory-filename] ...

    

    Context:server config, virtual host
    

    Status:Base
    

    Module:mod_userdir
    

    

    
    The UserDir directive sets the real
    directory in a user's home directory to use when a request for a
    document for a user is received. Directory-filename is
    one of the following:
    

    
      
      
    • The name of a directory or a pattern such as those shown
      below.
      • 

      
    • The keyword disabled. This turns off
      all username-to-directory translations except those
      explicitly named with the enabled keyword (see
      below).
      • 

      
    • The keyword disabled followed by a
      space-delimited list of usernames. Usernames that appear in
      such a list will never have directory translation
      performed, even if they appear in an enabled
      clause.
      • 

      
    • The keyword enabled followed by a
      space-delimited list of usernames. These usernames will have
      directory translation performed even if a global disable is
      in effect, but not if they also appear in a
      disabled clause.
      • 
    
    

    
    If neither the enabled nor the
    disabled keywords appear in the
    Userdir directive, the argument is treated as a
    filename pattern, and is used to turn the name into a directory
    specification. A request for
    http://www.example.com/~bob/one/two.html will be
    translated to:
    

    
    
      
    UserDir directive used
          Translated path
    
      
    UserDir public_html
          ~bob/public_html/one/two.html
    
      
    UserDir /usr/web
          /usr/web/bob/one/two.html
    
      
    UserDir /home/*/www
          /home/bob/www/one/two.html
    
    
    

    
    The following directives will send redirects to the client:
    

    
    
      
    UserDir directive used
          Translated path
    
      
    UserDir http://www.example.com/users
          http://www.example.com/users/bob/one/two.html
    
      
    UserDir http://www.example.com/*/usr
          http://www.example.com/bob/usr/one/two.html
    
      
    UserDir http://www.example.com/~*/
          http://www.example.com/~bob/one/two.html
    
    
    

    
    
      Be careful when using this directive; for instance,
      "UserDir ./" would map "/~root" to
      "/" - which is probably undesirable. It is strongly
      recommended that your configuration include a "UserDir
      disabled root" declaration.  See also the Directory directive and the Security Tips page for
      more information.
    
    

    
    Additional examples:
    

    
    To allow a few users to have UserDir directories, but
    not anyone else, use the following:
    

    
    UserDir disabled
UserDir enabled user1 user2 user3
    


    
    To allow most users to have UserDir directories, but
    deny this to a few, use the following:
    

    
    UserDir disabled user4 user5 user6
    


    
    It is also possible to specify alternative user directories.
    If you use a command like:
    

    
    UserDir "public_html" "/usr/web" "http://www.example.com/"
    


    
    With a request for
    http://www.example.com/~bob/one/two.html, will try to
    find the page at ~bob/public_html/one/two.html first, then
    /usr/web/bob/one/two.html, and finally it will send a
    redirect to http://www.example.com/bob/one/two.html.
    

    
    If you add a redirect, it must be the last alternative in the list.
    Apache httpd cannot determine if the redirect succeeded or not, so if you have
    the redirect earlier in the list, that will always be the alternative
    that is used.
    

    
    User directory substitution is not active by default in versions
    2.1.4 and later.  In earlier versions, UserDir public_html

    概要
    

    
    このモジュールはクライアントリクエストの forensic ロギングを
    行ないます。ログ収集はリクエストの処理の前と後に行なわれますので、
    forensic ログは各リクエストに対して二行ログ収集します。
    Forensic ロガーは非常に厳密です。これは以下のことを意味します:
    

    
      
    
    • フォーマットは固定です。実行時にロギングフォーマットを変更することは
    できません。
      • 
    
    • データを書けない場合は子プロセスはその場で終了し、さらにコアを
    ダンプするかもしれません (CoreDumpDirectory ディレクティブの設定に依ります)。
      • 
    
    

    
    Forensic ログの出力を検査するためには、
    配布物の support ディレクトリにある check_forensic 
    スクリプトが役に立つでしょう。
    

    


    top
    

    

    Forensic ログフォーマット
    
    
    各リクエストは2回ログ収集されます。最初はリクエストが処理される
    前 (つまり、ヘッダを受け取った後) です。2度目のログは
    リクエストが処理された後、通常のログ収集と同じときに
    行なわれます。
    

    
    各リクエストを識別するために、リクエストには
    一意なリクエスト ID が割り当てられます。この forensic ID は
    フォーマット文字列 %{forensic-id}n を使うことで
    通常の transfer ログにログ収集することもできます。
    mod_unique_id を使っている場合は、それが生成する
    ID が使われます。
    

    
    最初の行は forensic ID、リクエスト行と受け取ったすべてのヘッダを
    パイプ文字 (|) で分離してログ収集します。
    例えば以下のようになります (実際はすべて同じ行になります):
    

    
    
        +yQtJf8CoAB4AAFNXBIEAAAAA|GET /manual/de/images/down.gif
        HTTP/1.1|Host:localhost%3a8080|User-Agent:Mozilla/5.0 (X11;
        U; Linux i686; en-US; rv%3a1.6) Gecko/20040216
        Firefox/0.8|Accept:image/png, etc...
    
    

    
    最初のプラス文字がこのログは最初のログであることを示します。
    二番目の行はマイナス文字と ID のみです:
    

    
    
      -yQtJf8CoAB4AAFNXBIEAAAAA
    
    

    
    check_forensic スクリプトは引数としてログファイルの名前を
    取ります。+/- の ID の組を調べ、完了していない
    リクエストがある場合は警告を発します。
    

    top
    

    

    セキュリティの問題
    
    
    ログファイルが保存されるディレクトリがサーバを起動したユーザ
    以外で書き込み可能になっているときにセキュリティが破られる可能性が
    あることについての詳細はセキュリティのこつを
    参照してください。

    ForensicLog ディレクティブ
    

    

    説明:Forensic ログのファイル名を設定する
    

    構文:ForensicLog filename|pipe
    

    コンテキスト:サーバ設定ファイル, バーチャルホスト
    

    ステータス:Extension
    

    モジュール:mod_log_forensic
    

    
    
    ForensicLog ディレクティブは forensic 解析のための
    サーバへのリクエストをログ収集に使います。
    各ログエントリには、普通の CustomLog ディレクティブを使ってリクエストと関連付けることの
    できる
    一意な ID が割り当てられます。mod_log_forensic は
    forensic-id というトークンを作成し、フォーマット文字列
    %{forensic-id}n を使うことでそのトークンを transfer ログに
    追加することができます。
    

    
    引数はログが書き出される位置を指定し、以下の 2種類の値のどちらかを
    取ることができます:
    

    
    
      
    filename
    
      
    ServerRoot からの
      相対ファイル名
    

      
    pipe
    
      
    パイプ文字 "|" と、その後にログ情報を標準入力から
      受け取るプログラム。プログラム名は ServerRoot からの相対パスとしても
      指定できます。

      
    セキュリティ:
    
      
    プログラムを使う場合、そのプログラムは httpd を起動したユーザで
      実行されます。つまり、サーバが root で実行された場合は root で
      実行されるということです。プログラムが安全であるか、より権限の少ない
      ユーザに切り替えるようになっていることを確かめてください。
    
      
    

      
    注
    
        
    Unix 以外のプラットフォームでファイル名を入力するときは、
        プラットフォームがバックスラッシュの使用を許可している場合でも、
        スラッシュのみが使われるように気をつけてください。
        普通は設定ファイルすべてにおいて、スラッシュの方を使用するように
        してください。

    Apache Module mod_vhost_alias

    Description:Provides for dynamically configured mass virtual
hosting
    

    Status:Extension
    

    Module Identifier:vhost_alias_module
    

    Source File:mod_vhost_alias.c
    

    Summary
    

    
    This module creates dynamically configured virtual hosts, by
    allowing the IP address and/or the Host: header of
    the HTTP request to be used as part of the pathname to
    determine what files to serve. This allows for easy use of a
    huge number of virtual hosts with similar configurations.
    

    
    Note
    
      
    If mod_alias or mod_userdir are
      used for translating URIs to filenames, they will override the
      directives of mod_vhost_alias described below. For
      example, the following configuration will map 
      /cgi-bin/script.pl to 
      /usr/local/apache2/cgi-bin/script.pl in all cases:
    

      
    ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/"
VirtualScriptAlias "/never/found/%0/cgi-bin/"

    Directory Name Interpolation
    
    

    
    All the directives in this module interpolate a string into
    a pathname. The interpolated string (henceforth called the
    "name") may be either the server name (see the UseCanonicalName
    directive for details on how this is determined) or the IP
    address of the virtual host on the server in dotted-quad
    format. The interpolation is controlled by specifiers inspired
    by printf which have a number of formats:
    


    


    %%
insert a %
    


    %p
insert the port number of the virtual host
    


    %N.M
insert (part of) the name
    


    

    
    N and M are used to specify
    substrings of the name. N selects from the
    dot-separated components of the name, and M
    selects characters within whatever N has selected.
    M is optional and defaults to zero if it isn't
    present; the dot must be present if and only if M
    is present. The interpretation is as follows:
    

    
    
      
      
    0
      the whole name
    

      
    1
      the first part
    

      
    2
      the second part
    

      
    -1
      the last part
    

      
    -2
      the penultimate part
    

      
    2+
      the second and all subsequent parts
    

      
    -2+
      the penultimate and all preceding parts
    

      
    1+ and -1+
      the same as 0
    
    
    

    
    If N or M is greater than the number
    of parts available a single underscore is interpolated.

    Examples
    
    

    
    For simple name-based virtual hosts you might use the
    following directives in your server configuration file:
    

    
    UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/vhosts/%0"
    


    
    A request for
    http://www.example.com/directory/file.html will be
    satisfied by the file
    /usr/local/apache/vhosts/www.example.com/directory/file.html.
    
    

    
    For a very large number of virtual hosts it is a good idea
    to arrange the files to reduce the size of the
    vhosts directory. To do this you might use the
    following in your configuration file:
    

    
    UseCanonicalName    Off
VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2"
    


    
    A request for
    http://www.domain.example.com/directory/file.html
    will be satisfied by the file
    /usr/local/apache/vhosts/example.com/d/o/m/domain/directory/file.html.
    

    
    A more even spread of files can be achieved by hashing from the
    end of the name, for example: 
    


    VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.-1/%2.-2/%2.-3/%2"
    


    
    The example request would come from
    /usr/local/apache/vhosts/example.com/n/i/a/domain/directory/file.html.
    

    
    Alternatively you might use: 
    


    VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2.4+"
    


    
    The example request would come from
    /usr/local/apache/vhosts/example.com/d/o/m/ain/directory/file.html.
    


     A very common request by users is the ability to point multiple domains to multiple 
document roots without having to worry about the length or number of parts of the 
hostname being requested. If the requested hostname is sub.www.domain.example.com
 instead of simply www.domain.example.com, then using %3+ will result in the document
root being /usr/local/apache/vhosts/domain.example.com/... instead of the
intended example.com directory. In such cases, it can be beneficial to use 
the combination %-2.0.%-1.0, which will always yield the domain name and the 
tld, for example example.com regardless of the number of subdomains appended 
to the hostname. As such, one can make a configuration that will direct all first, second 
or third level subdomains to the same directory:

    

    VirtualDocumentRoot "/usr/local/apache/vhosts/%-2.0.%-1.0"
    


    
In the example above, both www.example.com as well as www.sub.example.com
or example.com will all point to /usr/local/apache/vhosts/example.com.

    

    
    For IP-based virtual hosting you might use the following in
    your configuration file:
    

    
    UseCanonicalName DNS
VirtualDocumentRootIP "/usr/local/apache/vhosts/%1/%2/%3/%4/docs"
VirtualScriptAliasIP  "/usr/local/apache/vhosts/%1/%2/%3/%4/cgi-bin"
    


    
    A request for
    http://www.domain.example.com/directory/file.html
    would be satisfied by the file
    /usr/local/apache/vhosts/10/20/30/40/docs/directory/file.html
    if the IP address of www.domain.example.com were
    10.20.30.40. A request for
    http://www.domain.example.com/cgi-bin/script.pl would
    be satisfied by executing the program
    /usr/local/apache/vhosts/10/20/30/40/cgi-bin/script.pl.
    

    
    If you want to include the . character in a
    VirtualDocumentRoot directive, but it clashes with
    a % directive, you can work around the problem in
    the following way:
    


    VirtualDocumentRoot "/usr/local/apache/vhosts/%2.0.%3.0"
    


    
    A request for
    http://www.domain.example.com/directory/file.html
    will be satisfied by the file
    /usr/local/apache/vhosts/domain.example/directory/file.html.
    

    
    The LogFormat
    directives %V and %A are useful
    in conjunction with this module.

    VirtualDocumentRoot Directive
    

    

    Description:Dynamically configure the location of the document root
for a given virtual host
    

    Syntax:VirtualDocumentRoot interpolated-directory|none
    

    Default:VirtualDocumentRoot none
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_vhost_alias
    

    

    
    The VirtualDocumentRoot directive allows you to
    determine where Apache HTTP Server will find your documents based on the
    value of the server name. The result of expanding
    interpolated-directory is used as the root of the
    document tree in a similar manner to the DocumentRoot directive's argument.
    If interpolated-directory is none then
    VirtualDocumentRoot is turned off. This directive
    cannot be used in the same context as VirtualDocumentRootIP.
    


    Note
    
VirtualDocumentRoot will override any DocumentRoot directives you may have put in the same 
context or child contexts. Putting a VirtualDocumentRoot 
in the global server scope will effectively override DocumentRoot directives in any virtual hosts defined later 
on, unless you set VirtualDocumentRoot to None 
in each virtual host.

    VirtualDocumentRootIP Directive
    

    

    Description:Dynamically configure the location of the document root
for a given virtual host
    

    Syntax:VirtualDocumentRootIP interpolated-directory|none
    

    Default:VirtualDocumentRootIP none
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_vhost_alias
    

    


    The VirtualDocumentRootIP directive is like the
    VirtualDocumentRoot
    directive, except that it uses the IP address of the server end
    of the connection for directory interpolation instead of the server
    name.

    VirtualScriptAlias Directive
    

    

    Description:Dynamically configure the location of the CGI directory for
a given virtual host
    

    Syntax:VirtualScriptAlias interpolated-directory|none
    

    Default:VirtualScriptAlias none
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_vhost_alias
    

    

    
    The VirtualScriptAlias directive allows you to
    determine where Apache httpd will find CGI scripts in a similar
    manner to VirtualDocumentRoot does for other documents. It matches
    requests for URIs starting /cgi-bin/, much like ScriptAlias
    /cgi-bin/ would.

    VirtualScriptAliasIP Directive
    

    

    Description:Dynamically configure the location of the CGI directory for
a given virtual host

    Default:VirtualScriptAliasIP none
    

    Context:server config, virtual host
    

    Status:Extension
    

    Module:mod_vhost_alias
    

    

    
    The VirtualScriptAliasIP directive is like the
    VirtualScriptAlias
    directive, except that it uses the IP address of the server end
    of the connection for directory interpolation instead of the server
    name.

    Descripción
    

    
    Una breve descripción del propósito de la directiva.
    

    top
    

    

    Sintaxis
    

    
    Indica el formato de la directiva tal y como aparecería en un fichero de 
    configuración. Esta sintaxis es muy específica de cada directiva, y se 
    describe con detalle en la definición de la directiva. Generalmente, el 
    nombre de la directiva va seguido de una serie de uno o más parámetros 
    separados por un espacio. Si un parámetro contiene un espacio, éste debe 
    especificarse entre comillas dobles. Los parámetros opcionales van 
    especificados entre corchetes. Donde un parámetro puede tener uno o más 
    valores, los valores posibles se separan con barras verticales "|". El Texto
    Literal se muestra con la fuente por defecto, mientras que los distintos 
    tipos de parámetros para los que una sustitución resulta necesaria son 
    enfatizados. Las directivas que pueden tomar una lista variada de 
    parámetros acaban en "..." indicando que el último parámetro se repite.
    

    
    Las Directivas usan un gran número de diferentes tipos de parámetros. A 
    continuación definimos algunos de los más comunes.
    

    
    
      
    URL
    
      
    Un Localizador de Recursos Uniforme, incluye un esquema,
		  nombre de host, y un path opcional como en
      http://www.example.com/path/to/file.html
    

      
    Ruta de URL
    
      
    La parte de una url que sigue al esquema y el
		  nombre de host como en /path/to/file.html. El
      url-path representa una vista-web de un recurso, en
      contraposición a una vista de sistema-de-ficheros.
    

      
    Ruta del Fichero
    
      
    La ruta a un fichero en el sistema de ficheros local que
		  comienza desde el directorio raíz como en
      /usr/local/apache/htdocs/path/to/file.html.
      A menos que se especifique, una ruta de fichero que no comienza
      con una barra "/" se tratará como una ruta relativa a ServerRoot.
    

      
    Ruta del Directorio
    

      
    La ruta a un directorio en el sistema de ficheros local que
      comienza con el directorio ráiz como en
      /usr/local/apache/htdocs/path/to/.
    

      
    Nombre del Fichero
    

      
    El nombre de un fichero sin ir acompañado de información de la ruta
      como en file.html.
    

      
    regex
    

      
    Una 
      expresión regular compatible con Perl. La definición
      de directiva especificará contra qué se compara la
      regex.
    

      
    extensión
    

      
    En general, esta es la parte del nombre de fichero
      que sigue al último punto. Sin embargo, Apache reconoce múltiples
      extensiones de fichero, así que si un nombre de fichero
      contiene más de un punto, cada parte separada por un punto del
      nombre de fichero después del primer punto es una extensión.
      Por ejemplo, el nombre de fichero file.html.en
      contiene dos extensiones: .html y
      .en. Para las directivas de Apache, podrá especificar
      la extensiones con o sin el punto inicial. Además, las 
      extensiones no son sensibles a mayúsculas o minúsculas.
    

      
    Tipo MIME
    

      
    Un método de describir el formato de un fichero que está formado
      por un tipo de formato mayor y un tipo de formato menor, separados de
      de una barra como en text/html.
    

      
    Variable de Entorno
    

      
    El nombre de una variable de entorno
      definida en el proceso de configuración de Apache. Tenga en cuenta
      que esto no es necesariamente lo mismo que la variable de entorno
      de un sistema operativo. Vea la documentación de variable de entorno para
      más detalles.
    
    
    

    top
    

    

    Por defecto
    

    
    Si la directiva tiene un valor por defecto (p.ej., si
    la omite de la configuración completamente, el servidor Web Apache
    se comportará como si la hubiera configurado con un valor en 
    particular), se describe aquí. Si no tiene valor por defecto, esta 
    sección debería	indicar "Ninguno". Tenga en cuenta que el 
    valor por defecto listado aquí no es necesariamente el mismo que el   
    valor que toma la directiva en el httpd.conf por defecto distribuido 
    con el servidor.
    

    top
    

    

    Contexto
    

    
    Esto indica dónde se acepta la directiva en los ficheros de 
    configuración. Es una lista separada por comas para uno o más de los 
    siguientes valores:
    

    
    
      
    server config
    

      
    Esto indica que la directiva puede usarse en los ficheros de 
		  configuración del servidor (p.ej., httpd.conf),
		  pero not dentro de cualquier contenedor
      <VirtualHost>
      o <Directory>. 
		  No se permite en ficheros .htaccess de ninguna 
		  manera.
    

      
    virtual host
    

      
    Este contexto significa que la directiva puede aparecer dentro de un
      contenedor <VirtualHost>
      en el fichero de configuración del servidor.
    

      
    directory
    

      
    Una directiva marcada como válida en este contexto puede usarse dentro
      de contenedores <Directory>, <Location>, <Files>, <If>,  <Proxy> en los ficheros de
      configuración del servidor, sujeta a las restricciones destacadas en
      las Secciones de Configuración.
    

      
    .htaccess
    

      
    Si una directiva es válida en este contexto, significa que puede 
      aparecer dentro de ficheros .htaccess de contexto de 
      directorio. Aunque podría no ser procesada, dependiendo de la 
      configuración activa de AllowOverride en ese 
      momento.
     
    
    

    
    La directiva solo se permite dentro del contexto designado; si
    intenta usarlo en algún otro, obtendrá un error de configuración que 
    impedirá que el servidor gestione correctamente las solicitudes en ese
    contexto, o impedirá que el servidor pueda funcionar completamente --
    p.ej., el servidor no arrancará.
    

    
    Las ubicaciones válidas para la directiva son actualmente el resultado de 
    un Boolean OR de todos los contextos listados. En otras palabras, una 
    directiva que está marcada como válida en 
    "server config, .htaccess" puede usarse en el fichero
    httpd.conf y en ficheros .htaccess, pero no dentro 
    de contenedores <Directory> 
    o <VirtualHost>.
    

    top
    

    

    Override
    

    
    Este atributo de directiva indica qué Override de configuración debe 
    estar activo para que la directiva se procese cuando aparece en un fichero 
    .htaccess. Si el contexto de la 
    directiva no permite que aparezca en ficheros .htaccess, 
    entonces no se listará ningún contexto.
    

    
    Los Override se activan con la directiva AllowOverride, si se aplican a un ámbito en 
    particular (como por ejemplo un directorio) y todos sus descendientes, a 
    menos que se modifique más adelante por otras directivas
    AllowOverride en niveles
    inferiores. La documentación para la directiva también muestra una lista de
    los posibles nombres de Override disponibles.

    Estado
    

    
    Esto indica cuan vinculada está esta directiva al servidor Web de Apache; 
    o en otras palabras, puede que necesite recompilar el servidor con un 
    conjunto mejor de módulos para obtener acceso a esta directiva y su 
    funcionalidad. Valores posibles para estar directiva son:
    

    
    
      
    Core
    

      
    Si una directiva aparece listada con estado "Core", eso significa
      que forma parte de las partes más internas del Servidor Apache Web, y que
      siempre está disponible.
    

      
    MPM
    

      
    La directivas facilitadas por un
      Módulo de Multi-Proceso están etiquetadas con
      Estado "MPM". Este tipo de directiva estará disponible si y sólo si está 
      usando uno de los MPM listados en la línea Módulo 
      de la definición de la directiva.
    

      
    Base
    

      
    Una directiva listada con estado "Base" está facilitada por uno
      de los módulos estándar de Apache que están compilados con el servidor
      por defecto, y por tanto está normalmente disponible a menos que usted 
      haga las acciones necesarias para eliminar este módulo de su 
      configuración.
    

      
    Extensión
    

      
    Una directiva con estado "Extensión" está facilitada por uno de los 
      módulos incluidos en el kit del servidor Apache, pero el módulo no 
      está compilado generalmente dentro del servidor. Para activar esta y su
      funcionalidad, necesirará cambiar la configuración de compilación
      del servidor y recompilar Apache.
    

      
    Experimental
    

      
    El estado "Experimental" indica que la directiva está disponible como
      parte del kit de Apache, pero usted tendrá que ir por su cuenta si intenta
      usarla. La directiva se documenta para aportar información, pero no tiene
      por qué estar soportada de manera oficial. El módulo que provee esta 
      directiva puede o puede que no esté compilado por defecto, compruebe
      la parte superior de la página que describe la direcitiva y el módulo para
      ver las anotaciones sobre su disponibilidad.

    Compatibilidad
    

    
    Si la directiva no era parte de la distribución original de Apache 
    versión 2, la versión en la que se introdujo debería estar referida aquí. 
    Además, si la direcitva solo está disponible en ciertas plataformas, se verá
    anotado aquí.

    Fichier Source:mod_http2.c
    

    Compatibilité:Disponible à partir de la version 2.4.17 du serveur
    HTTP Apache
    

    Sommaire
    

	
    Ce module ajoute le support de HTTP/2 (RFC 7540) au serveur HTTP
	Apache.
    
        
        
    Il s'appuie sur la bibliothèque libnghttp2 pour implémenter le
	moteur de base http/2.
    
        
        
    Pour mettre en oeuvre les fonctionnalités décrites dans ce
	document, vous devez activer HTTP/2 en utilisant la directive
	Protocols. HTTP/2 n'imposant
	pas de chiffrement, deux protocoles sont disponibles :
	h2 (HTTP/2 avec TLS) at h2c (HTTP/2 avec TCP).
    

	
    Voici deux types de configuration courant :
    

	
    HTTP/2 dans un contexte de serveur virtuel (TLS seulement)
    
        
    Protocols h2 http/1.1
    

	
    Permet une négociation HTTP/2 (h2) via TLS ALPN au sein d'un
	<VirtualHost>
	sécurisé. La vérification du préambule HTTP/2 (mode direct, voir
	H2Direct) est désactivée par
	défaut pour h2.
    
        
    
 
        
    HTTP/2 dans un contexte de serveur (TLS et texte pur)
    
	
    Protocols h2 h2c http/1.1
    

	
    Permet une négociation HTTP/2 (h2) via TLS ALPN au sein d'un
	<VirtualHost>
	sécurisé. Permet aussi une négociation HTTP/2 en texte pur (h2c) en
	effectuant une mise à jour depuis une connexion initiale HTTP/1.1 ou via
	une vérification du préambule HTTP/2 (mode direct, voir
	H2Direct).
    
        
    
 
        
    Si vous avez besoin d'informations supplémentaires à propos du
	protocole, veuillez vous reporter à la HTTP/2 FAQ.

    Comment ça marche ?
    
    
    
    Quantification des ressources
    supplémentaires nécessaires à HTTP/2
    
        
    
            Activer HTTP/2 sur votre serveur Apache a un impact sur la
	    consommation de ressources, et si votre site est très actif, il est
	    conseillé d'en prendre sérieusement en compte les implications.
        
    
        
    
            HTTP/2 attribue à chaque requête qu'il reçoit son propre thread
	    de travail pour son traitement, la collecte des résultats et
	    l'envoie de ces derniers au client. Pour y parvenir, il lui faut
	    lancer des threads supplémentaires, et ceci constituera le premier
	    effet notable de l'activation de HTTP/2.
        
    
        
    
	    Dans l'implémentation actuelle, ces threads de travail font partie
	    d'un jeu de threads distinct de celui des threads de travail du MPM
	    avec lequel vous êtes familié. Il s'agit simplement du mode de
	    fonctionnement actuel, et il n'en sera pas obligatoirement toujours
	    ainsi (il est cependant probable que la situation restera inchangée
	    avec la version 2.4.x). De par ce mode de fonctionnement, les
	    threads de travail HTTP/2, ou plus simplement H2 ne seront pas
	    affichés par mod_status. De même, ils ne seront pas
	    pris en compte par les directives du style ThreadsPerChild. Par contre, ils
	    utilisent par défaut la valeur de ThreadsPerChild si vous n'avez pas
	    spécifié d'autres valeurs via H2MinWorkers et H2MaxWorkers.
        
    
        
    
            Autre changement à surveiller : la consommation de mémoire. En
	    effet, comme HTTP/2 conserve plus d'informations sur le serveur pour
	    gérer toutes les requêtes en cours, leurs priorités et
	    interdépendances, il aura toujours besoin de plus de mémoire que
	    pour un traitement en HTTP/1.1. Trois directives permettent de
	    limiter l'empreinte mémoire d'une connexion HTTP/2 : H2MaxSessionStreams, H2WindowSize et H2StreamMaxMemSize.
        
    
        
    
            La directive H2MaxSessionStreams permet de limiter
	    le nombre de requêtes simultanées qu'un client peut envoyer sur une
	    connexion HTTP/2. La valeur que vous allez définir dépend de votre
	    site. La valeur par défaut qui est de 100 est largement suffisante,
	    et à moins que vous ne soyez un peu juste en mémoire, je vous
	    conseille de ne pas la modifier. La plupart des requêtes qu'envoie
	    un client sont des requêtes de type GET sans corps qui n'utilisent
	    que très peu de mémoire en attendant le démarrage du traitement.
	    
        
    
        
    
            La directive H2WindowSize
	    permet de définir la taille maximale que peut avoir le corps d'une
	    requête que le client envoie avant d'attendre que le serveur
	    en demande d'avantage. En d'autres termes, il s'agit de la quantité
	    de données que le serveur peut stocker dans son tampon, valable pour
	    une requête.
        
    
        
    
	    En outre, la directive H2StreamMaxMemSize permet de définir
	    la quantité de données de la réponse qui doit être mise en tampon.
	    Chaque requête étant prise en charge par un thread H2Worker et
	    produisant des données que le serveur tente de transmettre au client
	    via une connexion HTTP/2, si le client n'est pas en mesure de lire
	    ces données assez rapidement, la connexion les mettra en tampon et
	    interrompra l'exécution du thread H2Worker correspondant.
        
    
        
    
    
    
    Serveurs virtuels et requêtes mal
    redirigées
    
        
    
            De nombreux site utilisent le même certificat TLS pour plusieurs
	    serveurs virtuels. Ce certificat référence un nom de serveur
	    générique comme '*.example.org' ou plusieurs noms de serveur
	    différents. Les navigateurs qui utilisent HTTP/2 détectent ce
	    comportement et réutilisent une connexion déjà ouverte pour ces
	    serveurs.
        
    
        
    
            Ceci améliore considérablement les performances, mais il y a un prix
	    à payer : il faut accorder un soin tout particulier à la
	    configuration de tels serveurs virtuels. Le problème réside dans le
	    fait que plusieurs requêtes pour plusieurs serveurs virtuels vont se
	    partager la même connexion TLS, et ceci empêche toute renégociation
	    car le standard HTTP/2 l'interdit.
        
    
        
    
            Ainsi, lorsque plusieurs de vos serveurs virtuels utilisent le même
	    certificat et si vous souhaitez utiliser HTTP/2 pour y accéder, vous
	    devez vous assurer que tous vos serveurs virtuels possèdent
	    exactement la même configuration SSL. En particulier, ils doivent
	    utiliser les mêmes protocole, algorithme de chiffrement et
	    configuration pour la vérification du client.
        
    
        
    
	    Dans le cas contraire, Apache httpd le détectera et renverra au
	    client un code de réponse spécial, 421 Misdirected Request.
        
    
    

    
    Variables d'environnement
    
        
        
    Ce module peut être configuré pour fournir des informations en

                Cette directive permet de définir la manière de gérer les
		contenus de fichiers dans les réponses. Lorsqu'elle est à off
		(sa valeur par défaut), les descripteurs de fichiers sont
		transmis par le processus de traitement de la requête vers la
		connexion principale en utilisant le système habituel de mise en
		réserve d'Apache pour gérer le durée de vie du fichier.
            
    
            
    
                Lorsqu'elle est à on, le contenu du fichier est
		recopier pendant le traitement de la requête et ces données
		mises en tampon sont transmises vers la connexion principale, ce
		qui s'avère avantageux lorsqu'un module tiers injecte dans la
		réponse des fichiers possédant des durées de vie différentes. 
            
    
            
    
                Un exemple de ces modules tiers : mod_wsgi qui peut
		injecter des descripteurs de fichiers dans la réponse. Ces
		fichiers sont fermés lorsque Python estime que le traitement est
		terminé, alors que mod_http2 est probablement
		encore loin d'en avoir fini avec eux.

                Cette directive permet d'activer/désactiver
		l'utilisation du mode HTTP/2 Direct. Elle doit être
		située dans une section <VirtualHost> afin d'activer la
		communication directe HTTP/2 pour le serveur virtuel
		considéré. 
            
    
            
    
                La notion de communication directe signifie que si les
		premiers octets reçus par le serveur correspondent à un
		en-tête HTTP/2, le protocole HTTP/2 est utilisé sans
		négociation supplémentaire. Ce mode est défini pour
		les transmissions en clair (h2c) dans la RFC 7540. Son
		utilisation avec les connexions TLS n'est pas
		officiellement supportée.
            
    
            
    
                Lorsque le protocole h2 ou h2c n'est pas activé via la
		directive Protocols, la recherche d'un en-tête HTTP/2 n'est
		jamais effectuée au sein d'une connexion. La directive
		H2Direct ne produit alors aucun effet. Ceci est
		important pour les connexions qui utilisent un protocole
		pour lequel une lecture initiale peut entraîner un
		blocage définitif comme NNTP.
            
    
            
    
                Pour un client qui sait qu'un serveur supporte h2c, la
		communication directe HTTP/2 dispense le client d'une
		mise à jour HTTP/1.1, ce qui entraîne une amélioration
		des performances et évite les restrictions sur les corps
		de requête suite à une mise à jour.
            
    
            
    
                Cette directive rend aussi h2c plus attractif pour les
		communications de serveur à serveur lorsque la connexion
		est sure ou peut être sécurisée d'une manière ou d'une
		autre.

                Cette directive permet de définir si les vérifications de
		sécurité sur les connexions HTTP/2 doivent être exclusivement en
		mode TLS (https:). Elle peut être placée au niveau du serveur
		principal ou dans une section <VirtualHost>. 
            
    
            
    
                Les vérifications de sécurité nécessitent TLSv1.2 au minimum et
		l'absence de tout algorithme de chiffrement listé dans la RFC
		7540, Appendix A. Ces vérifications seront étendues lorsque de
		nouveaux prérequis en matière de sécurité seront mis en place.
            
    
            
    
                Le nom provient des définitions Mozilla Security/Server
		Side TLS où il est question de "modern compatibility".
		Mozilla Firefox et d'autres navigateurs imposent la "modern
		compatibility" pour les connexions HTTP/2. Comme toute chose en
		matière de sécurité opérationnelle, c'est une cible mouvante
		susceptible d'évoluer dans le futur.
            
    
            
    
                Un des buts de ces vérifications dans mod_http2 tend à imposer
		ce niveau de sécurité pour toutes les connexions, et non
		seulement celles en provenance des navigateurs web. Un autre but
		est l'interdiction d'utiliser HTTP/2 en tant que protocole dans
		les négociations si les prérequis ne sont pas respectés.
            
    
            
    
                En fin de compte, la sécurité de la connexion TLS est déterminée
		par les directives de configuration du serveur pour mod_ssl.

		indépendamment à chaque trame que le module renvoie au client.
            
    
            
    
                Pour améliorer la dissimulation de la longueur des trames, on
		peut augmenter le nombre moyen d'octets de bourrage, mais cela
		augmente d'autant le trafic réseau. Le nombre optimal d'octets
		de bourrage dépend donc du type de trafic web que le serveur

                La valeur par défaut de 0 (aucun octet de bourrage) a été
		choisie dans un but de compatibilité ascendante. Il peut en
		effet exister des installations où les octets de bourrage ne
		sont pas souhaités ou sont néfastes. La cause principale peut
		provenir d'un client dont l'implémentation comporte des erreurs.

                Cette directive permet d'activer/désactiver
		l'utilisation de la fonctionnalité server push du
		protocole HTTP/2. 
            
    
            
    
                Lorsqu'un client demande une ressource particulière, le
		protocole HTTP/2 permet au serveur de lui fournir des
		ressources supplémentaires. Ceci s'avère utile lorsque
		ces ressources sont reliées entre elles, ce qui peut
		laisser supposer que le client va probablement les
		demander dans un délai plus ou moins long. Le mécanisme
		de pushing permet alors au client d'économiser le temps
		qu'il lui aurait fallu pour demander ces ressources
		supplémentaires lui-même. Par contre, fournir au client
		des ressources dont il n'a pas besoin ou qu'il possède
		déjà constitue une perte de bande passante.
            
    
            
    
                Les server pushes sont détectés en inspectant les
		en-têtes Link des réponses (voir
		https://tools.ietf.org/html/rfc5988 pour la
		spécification). Lorsqu'un lien spécifié de cette manière
		possède l'attribut rel=preload, il est
		considéré comme devant faire l'objet d'un push.
            
    
            
     
                Les en-têtes link des réponses sont soit définis par
		l'application, soit configurés via
		H2PushResource ou
		mod_headers comme suit :
            
    
            
    Exemple de configuration d'en-tête link via mod_headers
    <Location /index.html>
    Header add Link "</css/site.css>;rel=preload"
    Header add Link "</images/logo.jpg>;rel=preload"
</Location>
    

    
            
    
                Comme le montre l'exemple, il est possible d'ajouter
		autant d'en-têtes link que l'on souhaite à une réponse, ce qui déclenchera
		autant de pushes. Cette fonctionnalité doit donc être
		utilisée avec prudence car le module ne vérifie pas si
		une ressource n'a pas déjà été "pushée" vers un client.
            
    
            
     
                Les PUSH HTTP/2 sont activés par défaut. Vous pouvez
		activer/désactiver cette fonctionnalité pour toute connexion au
		serveur au niveau global ou serveur virtuel. Vous pouvez en
		outre désactiver PUSH pour un jeu de ressources dans une
		section Directory/Location. Notez que ceci permet de contrôler
		quelles ressources peuvent déclencher un PUSH, mais pas les
		ressources qui peuvent être envoyées via PUSH.
            
    
            
    Exemple
    H2Push off
    

    
            
    
                Enfin, il est important de savoir que les pushes ne se
		produisent que si le client en manifeste le désir ; la
		plupart des navigateurs le font, mais certains, comme
		Safari 9, ne le font pas. En outre, les pushes ne se produisent que
		pour les ressources de la même autorité que celle de la
		réponse originale.

                Cette directive permet de définir le nombre maximum de pushes

		placée dans une section <VirtualHost> afin de définir le nombre
		de pushes pour le serveur virtuel considéré. 
            
    
            
    
                Le journal des pushes enregistre un condensé (sous la forme d'un
		nombre de 64 bits) des ressources préchargées (leurs URLs) afin
		d'éviter les duplications de pushes pour une même connexion.
		Cependant, ces données ne sont pas conservées, et les clients
		qui ouvrent une nouvelle connexion se verront à nouveau affecter les
		mêmes pushes. A ce titre, une étude est en cours pour permettre
		au client de supprimer le condensé des ressources qu'il possède
		déjà, et par là-même de réinitialiser le journal des pushes à
		chaque nouvelle connexion.
            
    
            
    
                Si la taille maximale est atteinte, les nouvelles entrées
		remplacent les plus anciennes. Une entrée du journal nécessitant
		8 octets, un journal de 256 entrées consomme 2 Ko de mémoire.

    Compatibilité:Disponible à partir de la version 2.4.18 du serveur HTTP
	Apache. Nécessite la bibliothèque nghttp2 version 1.5.0 ou supérieure.
    

    
            
    
                Cette directive permet de définir une gestion de priorité des
		pushes en fonction du type de contenu de la réponse. Elle est en
		général définie au niveau du serveur principal, mais peut aussi
		l'être au niveau d'un serveur virtuel. 
            
    
            
    
                Les pushes HTTP/2 sont toujours liés à une requête client.
		Chaque paire requête/réponse de cette sorte, ou flux,
		possède une dépendance et un poids qui définissent la
		priorité du flux. 
            
    
            
    
                Lorsqu'un flux dépend d'un autre, disons X dépend de Y,
		alors Y reçoit toute la bande passante avant que X n'en reçoive
		ne serait-ce qu'une partie. Notez que cela ne signifie en rien
		que Y bloque X ; en effet, si Y n'a aucune donnée à envoyer,
		toute la bande passante qui lui est allouée peut être utilisée
		par X.
            
    
            
    
                Lorsque plusieurs flux dépendent d'un même autre flux, disons X1
		et X2 dépendent tous deux de Y, le poids détermine la
		bande passante allouée. Ainsi, si X1 et X2 possèdent le même
		poids, ils recevront tous deux la moitié de la bande passante
		disponible. Si le poids de X1 est égal au double de celui de X2,
		X1 recevra une bande passante double de celle de X2.
		
            
    
            
     
                En fin de compte, tout flux dépend du flux racine qui
		reçoit toute la bande passante disponible mais n'envoie jamais
		de données. Cette bande passante est ainsi répartie entre les flux
		enfants selon leur poids. Ces derniers l'utilisent alors pour
		envoyer leurs données ou pour la répartir entre leurs propres
		flux enfants, et ainsi de suite. Si aucun des flux enfants n'a
		de données à envoyer, la bande passante est attribuée à d'autres
		flux selon les mêmes règles.
            
    
            
     
                Ce système de priorités a été conçu de façon a toujours pouvoir
		utiliser la bande passante disponible tout en définissant des
		priorités et en attribuant des poids aux différents flux. Ainsi,
		tous les flux sont en général initialisés par le client qui
		lui-même définit les priorités.
            
    
            
    
                Seul le fait de savoir qu'un flux implique un PUSH permet au
		serveur de décider quelle est la priorité initiale d'un
		tel flux. Dans les exemples ci-dessous, X est le flux client. Il
		dépend de Y et le serveur décide de "PUSHer" les flux P1 et P2
		sur X.
            
    
            
    
                La règle de priorité par défaut est :
            
    
            
    Règle de priorité par défaut
    H2PushPriority * After 16
    

    
            
    
                Elle peut se traduire par "Envoyer un flux PUSH avec tout type
		de contenu et dépendant du flux client avec le poids 16". P1 et
		P2 seront alors envoyés après X, et comme leurs poids sont
		identiques, il se verront allouer la même quantité de bande
		passante.
            
    
            
    Règle de priorité entrelacée
    H2PushPriority text/css Interleaved 256
    

    
            
    
                Ce qui peut se traduire par "Envoyer toute ressource CSS dans la
		même dépendance et avec le même poids que le flux client". Si le
		type de contenu de P1 est "text/css", il dépendra de Y (comme X)
		et son poids effectif sera calculé selon la formule : P1ew
		= Xw * (P1w / 256). Si P1w est de 256, Le poids effectif
		de P1 sera le même que celui de X. Si X et P1 ont des données à
		envoyer, il se verront allouer la même quantité de bande
		passante.
            
    
            
    
                Avec un Pw de 512, un flux entrelacé et PUSHé aura un poids
		double de celui de X. Avec un poids de 128, son poids ne sera
		que la moitié de celui de X. Notez que les poids effectifs sont
		toujours plafonnés à 256.
		
            
    
            
    Règle de priorité Before
    H2PushPriority application/json Before
    

    
            
    
                Dans cet exemple, tout flux PUSHé dont le contenu est de type
		'application/json' sera envoyé avant X, ce qui rend P1
		dépendant de Y et X dépendant de P1. Ainsi, X sera mis en
		attente aussi longtemps que P1 aura des données à envoyer. Le
		poids effectif est hérité du flux client, et l'attribution d'un
		poids spécifique n'est pas autorisée.

		de priorités sont limitées par les ressources disponibles du
		serveur. Si un serveur ne dispose d'aucun processus/thread de
		travail pour les flux PUSHés, les données du flux considéré ne
		seront envoyées que lorsque les autres flux auront terminé
		l'envoi des leurs.
            
    
            
    
                Enfin et surtout, il convient de tenir compte de certaines
		particularités de la syntaxe de cette directive :
             
    
            
      
                
    1. '*' est la seule expression permettant de remplacer tout
		type de contenu. 'image/*' ne fonctionnera pas.
      2. 
                
    2. La dépendance par défaut est 'After'.
      3. 
                
    3. Il existe aussi des poids par défaut : pour 'After' le poids
		est de 16, alors que pour 'interleaved' il est de 256. 
                
      4. 
            
    
            
    Exemples de règles
    H2PushPriority application/json 32         # une règle de priorité 'After'
H2PushPriority image/jpeg before           # poid hérité
H2PushPriority text/css   interleaved      # poids de 256 par défaut

    Directive H2PushResource
    

    

    Description:Déclare des ressources à proposer ("pusher") au client

	Apache.
    

    
            
    
                Lorsqu'il sont activés pour un répertoire, les PUSHes HTTP/2 seront
		tentés pour tous les chemins ajoutés via cette directive. Cette
		dernière peut être utilisée plusieurs fois pour le même
		répertoire.
            
    
            
    
                Cette directive propose des ressources beaucoup plus tôt que les
		en-têtes Link de mod_headers.
		mod_http2 présente ces ressources au client via
		une réponse intermédiaire 103 Early Hints. Ceci
		implique que les clients qui ne supportent pas PUSH recevront
		quand-même rapidement des propositions de préchargement.
            
    
            
    
                A la différence de la définition d'en-têtes de réponse
		Link via mod_headers, cette
		directive n'aura d'effet que pour les connexions HTTP/2. 
            
    
            
    
                En ajoutant l'option critical à une telle
		ressource, le serveur la traitera prioritairement, et une fois
		les données disponibles, ces dernières seront envoyées avant les
		données de la requête principale.

    Module:mod_http2
    

    
            
    
                Cette directive permet de définir si les requêtes HTTP/2 doivent
		être sérialisées au format HTTP/1.1 pour être traitées par le
		noyau de httpd, ou si les données binaires reçues
		doivent être passées directement aux request_recs.
            
    
            
    
                La sérialisation dégrade les performances, mais garantit une
		meilleure compatibilité ascendante lorsque des filtres ou
		programmes accroche personnalisés en ont besoin.

                Cette directive permet de définir la quantité maximale de
		données en sortie mises en tampon mémoire pour un flux actif. Ce
		tampon mémoire n'est pas alloué pour chaque flux en tant que
		tel. Les quantités de mémoire sont définies en fonction de
		cette limite lorsqu'elles sont sur le point d'être allouées. Le
		flux s'arrête lorsque la limite a été atteinte, et ne reprendra
		que lorsque les données du tampon auront été transmises au
		client.

    Directive H2TLSCoolDownSecs
    

    

    Description:Durée d'inactivité d'une connexion TLS avant diminution de
	la taille des paquets
    

    Syntaxe:H2TLSCoolDownSecs seconds
    

    Défaut:H2TLSCoolDownSecs 1
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_http2
    

    Compatibilité:Disponible à partir de la version 2.4.18 du serveur HTTP
	Apache.
    

    
            
    
                Cette directive permet de spécifier le nombre de secondes avant
		lequel une connexion TLS inactive va diminuer
		la taille des paquets de données à une valeur inférieure (~1300
		octets). Elle peut être définie au niveau du serveur principal
		ou pour un <serveur
		virtuel> spécifique. 
            
    
            
    
                Voir la directive H2TLSWarmUpSize pour une description
		du "préchauffage" de TLS. La directive H2TLSCoolDownSecs met en
		lumière le fait que les connexions peuvent se détériorer au bout
		d'un certain temps (et au fur et à mesure des corrections du
		flux TCP), et cela même si elle sont inactives. Pour ne pas
		détériorer les performances d'une manière générale, il est par
		conséquent préférable de revenir à la phase de préchauffage
		lorsqu'aucune donnée n'a été transmise pendant un certain nombre
		de secondes. 
            
    
            
    
                Dans les situations où les connexions peuvent être considérées
		comme fiables, ce délai peut être désactivé en définissant cette
		directive à 0. 
            
    
            
    
                Dans l'exemple suivant, la directive est définie à 0, ce qui
		désactive tout retour à une phase de préchauffage des connexions
		TLS. Les connexions TLS déjà préchauffées conservent donc toujours
		leur taille de paquet de données maximale.
            
    
            
    Exemple
    H2TLSCoolDownSecs 0

    Directive H2TLSWarmUpSize
    

    

    Description:Taille des paquets durant la phase initiale de la connexion
	TLS
    

    Syntaxe:H2TLSWarmUpSize amount
    

    Défaut:H2TLSWarmUpSize 1048576
    

    Contexte:configuration globale, serveur virtuel
    

    Statut:Extension
    

    Module:mod_http2
    

    Compatibilité:Disponible à partir de la version 2.4.18 du serveur HTTP
	Apache.
    

    
            
    
                Cette directive permet de définir le nombre d'octets à envoyer
		dans les petits enregistrements TLS (~1300 octets) avant
		d'atteindre leur taille maximale de 16 ko pour les connexions
		https: HTTP/2. Elle peut être définie au niveau du serveur
		principal ou pour des <Serveurs virtuels> spécifiques. 
            
    
            
    
                Les mesures effectuées par les laboratoires de performances de
		Google montrent que les meilleurs performances sont atteintes
		pour les connexions TLS si la taille initiale des
		enregistrements reste en deça du niveau du MTU afin de permettre
		à la totatlité d'un enregistrement d'entrer dans un paquet IP.
            
    
            
    
                Comme TCP ajuste son contrôle de flux et sa taille de fenêtre,
		des enregistrements TLS trop longs peuvent rester en file
		d'attente ou même être perdus et devoir alors être réémis. Ceci
		est bien entendu vrai pour tous les paquets ; cependant, TLS a
		besoin de la totalité de l'enregistrement pour pouvoir le
		déchiffrer. Tout octet manquant rendra impossible l'utilisation
		de ceux qui ont été reçus.
            
    
            
    
                Lorqu'un nombre suffisant d'octets a été transmis avec succès,
		la connexion TCP est stable, et la taille maximale (16 ko) des
		enregistrements TLS peut être utilisée pour des performances
		optimales.
            
    
            
    
                Dans les architectures où les serveurs sont atteints par des
		machines locales ou pour les connexions de confiance seulement,
		la valeur de cette directive peut être définie à 0, ce qui a
		pour effet de désactiver la "phase de chauffage".
            
    
            
    
                Dans l'exemple suivant, la phase de chauffage est effectivement
		désactivée en définissant la directive à 0.

    Module:mod_http2
    

    
            
    
                Cette directive permet d'activer/désactiver l'utilisation de la
		méthode de mise à jour pour passer de HTTP/1.1 à HTTP/2. Elle
		doit être placée dans une section <VirtualHost> afin d'activer la mise à
		jour vers HTTP/2 pour le serveur virtuel considéré. 
            
    
            
    
                Cette méthode de changement de protocole est définie dans
		HTTP/1.1 et utilise l'en-tête "Upgrade" (d'où son nom) pour
		indiquer l'intention d'utiliser un autre protocole. Cet en-tête
		peut être présent dans toute requête sur une connexion HTTP/1.1.
            
    
            
    
                Elle activée par défaut pour les transmissions en clair
		(h2c), et désactivée avec TLS (h2), comme préconisé par la RFC
		7540. 
            
    
            
    
                Sachez cependant que les mises à jour ne sont acceptées que pour
		les requêtes qui ne possèdent pas de corps. Le requêtes de type
		POST et PUT avec un contenu ne feront jamais l'objet d'une mise
		à jour vers HTTP/2. Se référer à la documentation de la
		directive H2Direct pour
		envisager une alternative à Upgrade.
            
    
            
    
                Cette directive n'a d'effet que si h2 ou h2c est activé via la
		directive Protocols.

                Cette directive permet de définir la taille maximale des paquets
		de données envoyés par le client au serveur, et
		limite la quantité de données que le serveur doit mettre en
		tampon. Le client arrêtera d'envoyer des données sur un flux
		lorsque cette limite sera atteinte jusqu'à ce que le serveur
		indique qu'il dispose d'un espace suffisant (car il aura traité
		une partie des données).
            
    
                Cette limite n'affecte que les corps de requêtes, non les
		métadonnées comme les en-têtes. Par contre, elle n'affecte pas
		les corps de réponses car la taille maximale de ces derniers est
		gérée au niveau des clients.

    説明:クライアントへ送られる前にコンテンツを圧縮する
    

    ステータス:Extension
    

    モジュール識別子:deflate_module
    

    ソースファイル:mod_deflate.c
    

    概要
    

    
    mod_deflate モジュールは DEFLATE
    出力フィルタを提供します。これはサーバからの出力を、ネットワークを
    通してクライアントに送る前に圧縮することを可能にします。
    

    


    top
    

    

    サンプル設定
    
    
    下にせっかちな人向けの簡単な設定例を示します。
    

    
    数タイプのみ圧縮する
    
      AddOutputFilterByType DEFLATE text/html text/plain text/xml
    
    

    
    以下の設定はコンテンツをより圧縮しますが、ずっと複雑な設定になります。
    設定の隅々までよく理解しないで使わないでください。
    

    
    画像以外全て圧縮する
    
      <Location />
    
      
        # Insert filter
    
        SetOutputFilter DEFLATE
    
        
    
        # Netscape 4.x has some problems...
    
        BrowserMatch ^Mozilla/4         gzip-only-text/html
    
        
    
        # Netscape 4.06-4.08 have some more problems
    
        BrowserMatch ^Mozilla/4\.0[678] no-gzip
    
        
    
        # MSIE masquerades as Netscape, but it is fine
    
        # BrowserMatch \bMSIE             !no-gzip !gzip-only-text/html
    
        
    
        # Don't compress images
    
        SetEnvIfNoCase Request_URI \
    
        
          \.(?:gif|jpe?g|png)$ no-gzip dont-vary
    
            
        
    
        # Make sure proxies don't deliver the wrong content
    
        Header append Vary User-Agent env=!dont-vary
    
          
      </Location>

    圧縮を有効にする
    

    
    Output Compression
    
      
    圧縮機能は DEFLATE フィルタ
      により実装されています。以下のディレクティブはそのディレクティブのある
      コンテナ中のドキュメントを圧縮するようにします:
    
      
      
    
        SetOutputFilter DEFLATE
      
    

      
    よく使われているブラウザでは、すべてのコンテンツに対する
      圧縮を扱えるわけではありません。ですから、gzip-only-text/html 
      ノートを 1 にして、html ファイルに対してのみ
      圧縮が働くようにした方がよいかもしれません (以下参照)
      この値を 1 以外の値に設定した場合は無視されます。
    
      
      
    通常、特定のMIMEタイプについてのみ圧縮したいのであれば、
      AddOutputFilterByType
      ディレクティブを使用します。次に Apache のドキュメントの html
      ファイルのみの圧縮を有効にする例を示します。
    

      
    
        <Directory "/your-server-root/manual">
    
        
          AddOutputFilterByType DEFLATE text/html
    
            
        </Directory>
      
    

      
    全てのファイルタイプでの圧縮に問題を抱えているブラウザに対しては、
      BrowserMatch
      ディレクティブを使用して、特定のブラウザに no-gzip
      ノートをセットし、圧縮が行なわれないようにします。
      no-gzip と gzip-only-text/html
      を組み合わせることで上手く対処できます。
      この場合、前者が後者をオーバーライドします。
      上記の設定例の抜粋を
      次に示しますのでご覧下さい。
    

      
    
        BrowserMatch ^Mozilla/4         gzip-only-text/html
    
        BrowserMatch ^Mozilla/4\.0[678] no-gzip
    
        BrowserMatch \bMSIE             !no-gzip !gzip-only-text/html
      
    

      
    まず始めに User-Agent 文字列から Netscape Navigator
      4.x であるかどうかを調べます。これらのバージョンでは、
      text/html 以外のタイプの圧縮を扱うことができません。
      4.06, 4.07, 4.08 は html ファイルの伸張にも問題を抱えています。
      ですからこれらに対しては、完全に deflate フィルタをオフにします。
    

      
    3 番目の BrowserMatch
      ディレクティブで、推測したユーザーエージェントを修正します。
      なぜなら Microsoft Internet Explorer も "Mozilla/4" と特定されますが、
      これらは実際には圧縮を扱うことができるからです。
      User-Agent ヘッダを "MSIE"
      (\b は「単語の境界」を意味します) の追加文字で検査して、
      これ以前に設定した制限を再び解除します。
    

      
    注
    
        DEFLATE フィルタは必ず、PHP や SSI といった RESOURCE
        フィルタの後になります。
        DEFLATE フィルタは内部的なサブリクエストを関知しません。
      
    
      
    注
    
        SetEnv で設定される
        force-gzip 環境変数がありますが、これは
        ブラウザの accept-encoding 設定を無視し、圧縮した出力をします。
      
    

    
    
    出力の伸長
    
      
    mod_deflate モジュールは、gzip 圧縮されたレスポンス
      本文を inflate/uncompress するフィルタも提供しています。
      この機能を有効にするには、SetOutputFilter
      や AddOutputFilter を使って、
      INFLATE フィルタを出力フィルタチェインに挿入します。
      例えば次のようにします。
    

      
    
        <Location /dav-area>
    
        
          ProxyPass http://example.com/
    
          SetOutputFilter INFLATE
    
            
        </Location>
      
    

      
    この例では、example.com からの gzip 圧縮された出力を伸長し、
      その他のフィルタがさらにその出力を処理できるようにします。
      
    
      
    
    
    入力の伸張
    
      
    mod_deflate モジュールは、gzip
      で圧縮されたリクエスト本体を伸張するフィルタも提供しています。
      この機能を有効にするには、SetInputFilter
      か AddInputFilter を使用して、
      DEFLATE フィルタを入力フィルタチェインに組み込みます。
      例えば次のようになります。
    

      
    
        <Location /dav-area>
    
        
          SetInputFilter DEFLATE
    
            
        </Location>
      
    
      
      
    この設定であれば、Content-Encoding: gzip
      ヘッダを含むリクエストが来ると、本体は自動的に伸張されます。
      gzip リクエスト本体を送信するブラウザはあまりありません。
      しかし、例えば WebDAV
      クライアントの幾つかなど、特別なアプリケーションでリクエストの
      圧縮を実際にサポートしているものもあります。
    

      
    Content-Length に関する注意
    
        
    リクエスト本体それ自体を評価する場合は、Content-Length
        ヘッダを信用しないでください。Content-Length ヘッダは、
        クライアントから送信されるデータの長さを反映しているのであって、
        伸張されたデータストリームのバイトカウントではありません。
    
      
    
    

    top
    

    

    Proxy サーバでの扱い
    

    
    mod_deflate モジュールは Vary: Accept-Encoding
    HTTP 応答ヘッダを送信して、適切な Accept-Encoding
    リクエストヘッダを送信するクライアントに対してのみ、
    プロクシサーバがキャッシュした応答を送信するように注意を喚起します。
    このようにして、圧縮を扱うことのできないクライアントに
    圧縮された内容が送られることのないようにします。
    

    
    もし特別に何かに依存して除外したい場合、例えば User-Agent
    ヘッダなどに依存している場合、手動で Vary ヘッダを設定して、
    追加の制限についてプロクシサーバに注意を行なう必要があります。
    例えば User-Agent に依存して DEFLATE
    を追加する典型的な設定では、次のように追加することになります。
    

    
    
      Header append Vary User-Agent
    
    
    
    
    リクエストヘッダ以外の情報 (例えば HTTP バージョン)
    に依存して圧縮するかどうか決める場合、
    Vary ヘッダを * に設定する必要があります。
    このようにすると、仕様に準拠したプロクシはキャッシュを全く行なわなくなります。
    

    
    例
    
      Header set Vary *

    DeflateFilterNote ディレクティブは
    圧縮比に関するメモがリクエストに付加されることを指定します。
    メモ (note) の名前はディレクティブに指定された値です。
    メモはアクセスログに
    値を記録し、統計を取る目的にも使えます。
    

    
    例
    
      DeflateFilterNote ratio
    
      
    
      LogFormat '"%r" %b (%{ratio}n) "%{User-agent}i"' deflate
    
      CustomLog logs/deflate_log deflate
    
    

    
    ログからもっと精密な値を抽出したい場合は、type
    引数を使用して、データタイプをログのメモとして残すように指定できます。
    type は次のうちの一つです。
    

    
    
      
    Input
    
      
    フィルタの入力ストリームのバイトカウントをメモに保存する。
    

      
    Output
    
      
    フィルタの出力ストリームのバイトカウントをメモに保存する。
    

      
    Ratio
    
      
    圧縮率 (出力 / 入力 * 100) をメモに保存する。
      type 引数を省略した場合は、これがデフォルトとなります。

    Weighted Traffic Counting Algorithm
    
    
    
    Enabled via lbmethod=bytraffic, the idea behind this
    scheduler is very similar to the Request Counting method, with
    the following changes:
    

    
    lbfactor is how much traffic, in bytes, we want
    this worker to handle. This is also a normalized value
    representing their "share" of the amount of work to be done,
    but instead of simply counting the number of requests, we take
    into account the amount of traffic this worker has either seen
    or produced.
    

    
    If a balancer is configured as follows:
    

    
    worker
        a
        b
        c
    

    lbfactor
        1
        2
        1
    

    

    
    Then we mean that we want b to process twice the
    amount of bytes than a or c should. It does
    not necessarily mean that b would handle twice as
    many requests, but it would process twice the I/O. Thus, the
    size of the request and response are applied to the weighting
    and selection algorithm.
    

    
    Note: input and output bytes are weighted the same.

mod_proxy_scgi - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    Apache Module mod_proxy_scgi
    

    

    Available Languages:  en  |
 fr 
    

    

    Description:SCGI gateway module for mod_proxy
    

    Status:Extension
    

    Module Identifier:proxy_scgi_module
    

    Source File:mod_proxy_scgi.c
    

    Compatibility:Available in version 2.2.14 and later
    

    Summary
    

    
    This module requires the service of mod_proxy. It provides support for the
    SCGI protocol, version
    1.
    

    
    Thus, in order to get the ability of handling the SCGI protocol,
    mod_proxy and mod_proxy_scgi have to
    be present in the server.
    

    
    Warning
    
      
    Do not enable proxying until you have secured your server. Open proxy
      servers are dangerous both to your network and to the Internet at
      large.
    
    
    

    


    top
    

    

    Examples
    
    
    Remember, in order to make the following examples work, you have to
    enable mod_proxy and mod_proxy_scgi.
    

    
    Simple gateway
    ProxyPass "/scgi-bin/" "scgi://localhost:4000/"
    

    

    
    The balanced gateway needs mod_proxy_balancer and
    at least one load balancer algorithm module, such as
    mod_lbmethod_byrequests, in addition to the proxy
    modules listed above.  mod_lbmethod_byrequests is the
    default, and will be used for this example configuration.
    

    
    Balanced gateway
    ProxyPass "/scgi-bin/" "balancer://somecluster/"
<Proxy "balancer://somecluster">
    BalancerMember "scgi://localhost:4000"
    BalancerMember "scgi://localhost:4001"
</Proxy>
    

    

    top
    

    

    Environment Variables
    
    
    In addition to the configuration directives that control the
    behaviour of mod_proxy, an environment
    variable may also control the SCGI protocol
    provider:
    
    
    
        
    proxy-scgi-pathinfo
    
        
    By default mod_proxy_scgi will neither create
        nor export the PATH_INFO environment variable. This allows
        the backend SCGI server to correctly determine SCRIPT_NAME
        and Script-URI and be compliant with RFC 3875 section 3.3.
        If instead you need mod_proxy_scgi to generate
        a "best guess" for PATH_INFO, set this env-var.  The
        variable must be set before SetEnv
        is effective.  SetEnvIf can be
        used instead: SetEnvIf Request_URI . proxy-scgi-pathinfo

    ProxySCGIInternalRedirect Directive
    

    

    Description:Enable or disable internal redirect responses from the
backend
    

    Syntax:ProxySCGIInternalRedirect On|Off|Headername
    

    Default:ProxySCGIInternalRedirect On
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy_scgi
    

    Compatibility:The Headername feature is available in version
2.4.13 and later
    

    
    
    The ProxySCGIInternalRedirect enables the backend
    to internally redirect the gateway to a different URL. This feature
    originates in mod_cgi, which internally redirects the
    response if the response status is OK (200) and
    the response contains a Location (or configured alternate
    header) and its value starts with a slash (/). This value is 
    interpreted as a new local URL that Apache httpd internally redirects to.
    

    
    mod_proxy_scgi does the same as
    mod_cgi in this regard, except that you can turn off the
    feature or specify the use of a header other than Location.
    

    
    Example
        ProxySCGIInternalRedirect Off

# Django and some other frameworks will fully qualify "local URLs"
# set by the application, so an alternate header must be used.
<Location /django-app/>
    ProxySCGIInternalRedirect X-Location
</Location>
    

    


    

    top
    

    ProxySCGISendfile Directive
    

    

    Description:Enable evaluation of X-Sendfile pseudo response
header
    

    Syntax:ProxySCGISendfile On|Off|Headername
    

    Default:ProxySCGISendfile Off
    

    Context:server config, virtual host, directory
    

    Status:Extension
    

    Module:mod_proxy_scgi
    

    
    
    The ProxySCGISendfile directive enables the
    SCGI backend to let files be served directly by the gateway. This is useful
    for performance purposes — httpd can use sendfile or other
    optimizations, which are not possible if the file comes over the backend
    socket.  Additionally, the file contents are not transmitted twice.
    
    
    The ProxySCGISendfile argument determines the
    gateway behaviour:
    
    
    
    
    Off
    
    
    No special handling takes place.
    

    
    On
    
    
    The gateway looks for a backend response header called
    X-Sendfile and interprets the value as the filename to serve.
    The  header is removed from the final response headers. This is equivalent to
    ProxySCGISendfile X-Sendfile.
    

    
    anything else
    
    
    Similar to On, but instead of the hardcoded header name
    X-Sendfile, the argument is used as the header name.
    
    
    

    
    Example
    # Use the default header (X-Sendfile)
ProxySCGISendfile On

# Use a different header
ProxySCGISendfile X-Send-Static

    概要
    


    
    リクエストの綴りが間違っていたり、
    大文字小文字が違っていたりするために、Apache のコアサーバが
    ドキュメントへのリクエストへの応答を正しく提供できないことがあります。
    このモジュールは、他のすべてのモジュールがあきらめた後であったとしても、
    リクエストに合うドキュメントを見つけようとすることによりこの問題の
    解決を試みます。このモジュールはリクエストされたディレクトリにある
    それぞれのドキュメントの名前と、リクエストされたドキュメントの名前とを
    大文字小文字の区別を無視し、一文字までの
    綴りの間違い (文字の挿入/省略/隣合う文字の置換、間違った文字)
    を許可して比較することにより、目的を達成しようとします。
    この方法でリクエストに合うドキュメントの一覧が作成されます。
    

    
    ディレクトリをスキャンした後に、
    

    
      
      
    • 適切なドキュメントが見つからなかった場合、
      Apache はいつもと同じように処理をし、
      「ドキュメントが見つからない」というエラーを返します。
      • 

      
    • リクエストに「ほとんど」合うドキュメントが一つだけ見つかった場合、
       それがリダイレクト応答として返されます。
      • 

      
    • よく似たドキュメントが複数見つかった場合、
      そのリストがクライアントに返され、
      クライアントが正しい候補を選択できるようにします。

    Access Control
    

    

    Available Languages:  en  |

    Access control refers to any means of controlling access to any
    resource. This is separate from authentication and authorization.
    

    


    top
    

    

    Related Modules and Directives
    

    
    Access control can be done by several different modules. The most
    important of these are mod_authz_core and
    mod_authz_host. Also discussed in this document
    is access control using mod_rewrite.
    


    top
    

    

    Access control by host
    
    
    
    If you wish to restrict access to portions of your site based on the
    host address of your visitors, this is most easily done using
    mod_authz_host.
    
    

    
    The Require
    provides a variety of different ways to allow or deny access to
    resources. In conjunction with the RequireAll, RequireAny, and RequireNone directives, these
    requirements may be combined in arbitrarily complex ways, to enforce
    whatever your access policy happens to be.
    

    
    
    The Allow,
    Deny, and
    Order directives,
    provided by mod_access_compat, are deprecated and
    will go away in a future version. You should avoid using them, and
    avoid outdated tutorials recommending their use.
    
    

    
    The usage of these directives is:
    

    
    Require host address
Require ip ip.address
    


    
    In the first form, address is a fully qualified
    domain name (or a partial domain name); you may provide multiple
    addresses or domain names, if desired.
    

    
    In the second form, ip.address is an IP address, a
    partial IP address, a network/netmask pair, or a network/nnn CIDR
    specification. Either IPv4 or IPv6 addresses may be used.
    

    
    See the
    mod_authz_host documentation for further examples of this
    syntax.
    

    
    You can insert not to negate a particular requirement.
    Note, that since a not is a negation of a value, it cannot 
    be used by itself to allow or deny a request, as not true
    does not constitute false. Thus, to deny a visit using a negation,
    the block must have one element that evaluates as true or false.
    For example, if you have someone spamming your message
    board, and you want to keep them out, you could do the
    following:
    

    
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>
    


    
    Visitors coming from that address (10.252.46.165)
    will not be able to see the content covered by this directive. If, 
    instead, you have a machine name, rather than an IP address, you 
    can use that.
    

    
    Require not host host.example.com
    
    


    
    And, if you'd like to block access from an entire domain,
    you can specify just part of an address or domain name:
    

    
    Require not ip 192.168.205
Require not host phishers.example.com moreidiots.example
Require not host gov
    


    
    Use of the RequireAll, RequireAny, and RequireNone directives may be
    used to enforce more complex sets of requirements.
    


    top
    

    

    Access control by arbitrary variables
    

    
    Using the <If>,
    you can allow or deny access based on arbitrary environment
    variables or request header values. For example, to deny access
    based on user-agent (the browser type) you might do the
    following:
    

    
    <If "%{HTTP_USER_AGENT} == 'BadBot'">
    Require all denied
</If>
    


    
    Using the Require
    expr syntax, this could also be written as:
    


    
    Require expr %{HTTP_USER_AGENT} != 'BadBot'
    


    
    Warning:
    
    
    Access control by User-Agent is an unreliable technique,
    since the User-Agent header can be set to anything at all,
    at the whim of the end user.
    
    
    

    
    See the expressions document for a
    further discussion of what expression syntaxes and variables are
    available to you.
    


    top
    

    

    Access control with mod_rewrite
    

    
    The [F] RewriteRule flag causes a 403 Forbidden
    response to be sent. Using this, you can deny access to a resource based
    on arbitrary criteria.
    

    
    For example, if you wish to block access to a resource between 8pm
    and 7am, you can do this using mod_rewrite.
    

    
    RewriteEngine On
RewriteCond "%{TIME_HOUR}" ">=20" [OR]
RewriteCond "%{TIME_HOUR}" "<07"
RewriteRule "^/fridge"     "-" [F]
    


    
    This will return a 403 Forbidden response for any request after 8pm
    or before 7am. This technique can be used for any criteria that you wish
    to check. You can also redirect, or otherwise rewrite these requests, if
    that approach is preferred.
    

    
    The <If> directive,
    added in 2.4, replaces many things that mod_rewrite has
    traditionally been used to do, and you should probably look there first
    before resorting to mod_rewrite.
    


    top
    

    

    More information
    

    
    The expression engine gives you a
    great deal of power to do a variety of things based on arbitrary
    server variables, and you should consult that document for more
    detail.
    

    
    Also, you should read the mod_authz_core
    documentation for examples of combining multiple access requirements
    and specifying how they interact.
    

    
    See also the Authentication and Authorization
    howto.

    サーバサイドインクルードによって、既存の HTML
ドキュメントに動的なコンテンツを追加することができます。
    

    


    top
    

    

    はじめに
    
 
    関連モジュール関連ディレクティブ
    

    
    この記事は、通常は単に SSI と呼ばれる Server Side Includes
    を扱います。この記事においては、サーバでの SSI を許可するための設定と、
    現在の HTML ページに動的なコンテンツを加えるためのいくつかの基本的な
    SSI 技術を紹介します。
    

    
    記事の後半では、SSI ディレクティブで SSI
    と共に実行することができる条件文のような
    幾分高度な事柄について述べています。
    


    top
    

    

    SSI とは ?
    

    
    SSI (Server Side Includes) は、HTML
    ページ中に配置されるディレクティブであり、
    サーバでページを提供する時に評価されます。SSI は、CGI
    プログラムやその他の動的な技術で全てのページを提供せずに、
    動的に生成されたコンテンツを現在の HTML ページに加えます。
    

    
    どういう場合に SSI を使い、どういう場合にプログラムで
    ページを完全に生成するかは、ページのうちどの程度が静的であり、
    ページが提供されるたびに再計算する必要がどの程度あるかで通常は決定します。
    SSI は現在時刻のような小さい情報を加えるにはうってつけの方法です。
    しかし、そのページのほとんどの部分が提供時に生成される場合は、
    他の方法を探す必要があります。
    

    top
    

    

    SSI を許可するためのサーバの設定
    


    
    サーバで SSI を許可するには、httpd.conf
    ファイルまたは .htaccess
    ファイルに次のディレクティブを指定する必要があります:
    

    
        Options +Includes

    

    
    この指定は、ファイルを SSI
    ディレクティブで解析させることを許可するということを Apache
    に伝えます。ほとんどの設定ではお互いを上書きできる、複数の
    Options があることに
    注意してください。おそらく、設定が最後に評価されることを
    保証されるために、SSI を使用したいディレクトリに Options
    ディレクティブを適用する必要があるでしょう。
    

    
    全てのファイルが SSI
    ディレクティブで解析されるというわけではありません。
    どのファイルが解析されるかを Apache に伝える必要があります。
    これを行なうには二つ方法があります。
    次のディレクティブを使うことで、例えば .shtml
    のような特別なファイル拡張子を持つファイルを解析するよう
    Apache に伝えることができます:
    

    
        AddType text/html .shtml
    
        AddOutputFilter INCLUDES .shtml

    

    
    この方法の欠点は、もし現在のページに SSI ディレクティブを加えたい場合、
    それらのディレクティブが実行されるように 
    .shtml 拡張子にするため、そのページの名前と、
    そのページへの全てのリンクを変更しなければならないことです。
    

    
    もう一つの方法は、XBitHack
    ディレクティブを使用することです:
    

    
        XBitHack on

    

    
    XBitHack 
    は、ファイルの実行ビットが立っている場合、
    SSI ディレクティブにより解析することを Apache に伝えます。
    従って、SSI ディレクティブを現在のページに加えるためには、
    ファイル名を変更しなくてもよく、単に chmod
    を使用してファイルを実行可能にするだけで済みます。
    

    
        chmod +x pagename.html

    

    
    行なうべきではないことに関する短いコメント。時々誰かが、全ての
    .html ファイルを SSI で解析するよう Apache に伝えれば、
    わざわざ .shtml というファイル名にする必要がないといって
    薦めるのを見ることでしょう。こういう人たちは、おそらく
    XBitHack
    について聞いたことがないのでしょう。
    この方法について注意することは、たとえ SSI
    ディレクティブを全く含まない場合でも、Apache がクライアントに
    送る全てのファイルを最後まで読み込ませることになります。
    この方法はかなり処理を遅くするものであり、良くないアイデアです。
    

    
    もちろん、Windows ではそのような実行ビットをセット
    するようなものはありませんのでオプションが少し制限されています。
    

    
    デフォルトの設定では、Apache は SSI ページについて最終変更時刻や
    コンテンツの長さを HTTP ヘッダに送りません。
    動的なコンテンツであるため、それらの値を計算するのが難しいからです。
    このためドキュメントがキャッシュされなくなり、
    結果としてクライアントの性能が遅くなったように感じさせることになります。
    これを解決する方法が二つあります:
    

    
      
      
    1. XBitHack Full 設定を使用する。
      この設定により、もともと要求されたファイルの時刻を参照し、
      読み込まれるファイルの変更時刻を無視して最終変更時刻を決定するよう
      Apache に伝えます。
      2. 

      
    2. mod_expires
      で提供されているディレクティブを使用して、
      ファイルが無効になる時刻を明示します。これにより、
      ブラウザとプロキシにキャッシュが有効であることを通知します。
      3. 
    
    

    top
    

    

    基本的な SSI ディレクティブ
    

    
    SSI ディレクティブは以下の文法で記述します:
    

    
        <!--#element attribute=value attribute=value ... -->

    

    
    HTML のコメントのような書式をしているので、もし SSI
    を正しく動作可能にしなければ、ブラウザはそれを無視するでしょう。
    しかし、HTML ソース中では見えます。もし SSI を正しく設定したなら、
    ディレクティブはその結果と置き換えられます。
    

    
    element はたくさんあるものから一つ指定することができます。
    指定できるものの大多数については、次回もう少し詳しく説明します。
    ここでは、SSI で行なうことができる例をいくつか示します。
    


    今日の日付
    


    
        <!--#echo var="DATE_LOCAL" -->

    

    
    echo 要素は単に変数の値を出力します。
    CGI プログラムに利用可能な環境変数の全ての
    セットを含む多くの標準変数があります。また、set
    要素を用いることで、独自の変数を定義することができます。
    
    

    
    出力される日付の書式が好きではない場合、その書式を修正するために、
    config 要素に timefmt
    属性を使用することができます。
    


    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        Today is <!--#echo var="DATE_LOCAL" -->

    



    ファイルの変更日
    


    
        This document last modified <!--#flastmod file="index.html" -->

    

    
    この要素も timefmt
    フォーマットの設定に従います。
    



    CGI プログラムの結果を取り込む
    

    
    これは、全ての人のお気に入りである ``ヒットカウンタ'' のような
    CGI プログラムの結果を出力する SSI
    のより一般的な使用のうちの一つです。
    


    
        <!--#include virtual="/cgi-bin/counter.pl" -->

    



    top
    

    

    追加の例
    


    
    以下は、SSI を使用して HTML
    ドキュメントにおいてできることのいくつかの特別な例です。
    


    いつこのドキュメントは修正されたのか
?
    

    
    先に、ドキュメントが最後に変更されたのはいつかを
    ユーザに通知するために SSI を使用することができることを述べました。
    しかしながら、実際の方法は、いくぶん問題のままにしておきました。
    HTML ドキュメントに配置された次のコードは、ページにそのような
    タイムスタンプを入れるでしょう。もちろん、上述のように、
    SSI を正しく動作可能にしておく必要があります。
    

    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        This file last modified <!--#flastmod file="ssi.shtml" -->

    

    
    もちろん、ssi.shtml
    の部分を実際の当該ファイル名と置き換える必要があります。
    もし、あらゆるファイルに張ることができる一般的なコードを探しているなら、
    これは不便であるかもしれません。おそらくその場合は、
    そうする代わりに変数 LAST_MODIFIED
    を使用したいと考えるでしょう:
    

    
        <!--#config timefmt="%D" -->
    
        This file last modified <!--#echo var="LAST_MODIFIED" -->

    

    
    timefmt
    書式についてのより詳細については、お好みの検索サイトに行き、
    strftime で検索してみてください。文法は同じです。
    



    標準のフッタを挿入する
    


    
    もし数ページを超えるページを持つサイトを管理しているならば、
    全ページに対して変項を行なうことが本当に苦痛となり得ることが
    分かるでしょう。全てのページに渡ってある種の標準的な外観を
    維持しようとしているならば特にそうでしょう。
    

    
    ヘッダやフッタ用の挿入用ファイルを使用することで、
    このような更新にかかる負担を減らすことができます。
    一つのフッタファイルを作成し、それを include
    SSI コマンドで各ページに入れるだけで済みます。include
    要素は、file 属性または virtual
    属性のいずれかを使用してどのファイルを挿入するかを決めることができます。
    file 属性は、カレントディレクトリからの相対パスで示された
    ファイルパスです。
    それは / で始まる絶対ファイルパスにはできず、また、そのパスの一部に ../
    を含むことができないことを意味します。virtual
    属性は、おそらくより便利だと思いますが、提供するドキュメントからの相対
    URL で指定すべきです。それは / で始めることができますが、
    提供するファイルと同じサーバ上に存在しなくてはなりません。
    

    
        <!--#include virtual="/footer.html" -->

    

    
    私は最後の二つを組み合わせて、LAST_MODIFIED
    ディレクティブをフッタファイルの中に置くことがよくあります。
    SSI ディレクティブは、挿入用のファイルに含ませたり、
    挿入ファイルのネストをしたりすることができます。すなわち、
    挿入用のファイルは他のファイルを再帰的に挿入することができます。
    



    top
    

    

    他に何が設定できるのか ?
    


    
    時刻書式を config で設定できることに加えて、
    更に二つ config で設定することができます。
    

    
    通常、SSI ディレクティブで何かがうまくいかないときは、
    次のメッセージが出力されます。
    

    
        [an error occurred while processing this directive]

    

    
    このメッセージを他のものにしたい場合、config
    要素の errmsg 属性で変更することができます:
    

    
        <!--#config errmsg="[It appears that you don't know how to use SSI]" -->

    

    
    おそらく、エンドユーザはこのメッセージを決して見ることはありません。
    なぜなら、そのサイトが生きた状態になる前に SSI ディレクティブに関する
    全ての問題を解決しているはずだからです。(そうですよね?)
    

    
    そして、config において sizefmt
    属性を使用することで、
    返されるファイルサイズの書式を設定することができます。
    バイト数には bytes を、適当に Kb や Mb
    に短縮させるには abbrev を指定することができます。
    
    
    top
    

    

    コマンドの実行
    
    

    
    今後数ヶ月のうちに、小さな CGI プログラムと SSI
    を使用する記事を出したいと考えています。ここではそれとは別に、
    exec 要素によって行なうことができることを示します。
    SSI にシェル (正確には /bin/sh。Win32 ならば DOS シェル)
    を使用してコマンドを実行させることができます。
    下記の例では、ディレクトリリスト出力を行ないます。
    

    
        <pre>
    
        <!--#exec cmd="ls" -->
    
        </pre>

    

    
    Windows 上では、
    

    
        <pre>
    
        <!--#exec cmd="dir" -->
    
        </pre>

    

    
    Windows 上では、このディレクティブによっていくつかの奇妙な
    書式に気づくでしょう。なぜなら dir の出力が文字列
    ``<dir>'' を含み、ブラウザを混乱させるからです。
    

    
    この機能は非常に危険であり、どんなコードでも exec
    タグに埋め込まれてしまえば実行することに注意してください。例えば 
    `` ゲストブック '' のように、もし、
    ユーザがページの内容を編集できる状況にあるならば、
    この機能を確実に抑制してください。Options
    ディレクティブの IncludesNOEXEC 引数を指定することで、
    SSI は許可するけれど exec
    機能は許可しないようにすることができます。
    
    
    top
    

    

    高度な SSI テクニック
    


    
    コンテンツを出力することに加え、Apache SSI は変数を設定し、
    そして比較と条件分岐にその変数を使用できる機能を提供しています。
    
    


    警告
    

    
    この記事で述べた大部分の機能は、Apache 1.2
    以降を使用している場合のみ利用可能です。もちろん、もし Apache 1.2
    以降を使用してない場合、直ちにアップグレードする必要があります。
    さぁ、今それを行ないなさい。それまで待っています。
    



    変数を設定する
    

    
    set ディレクティブを使用して、
    後で使用するために変数を設定することができます。
    これは後の説明で必要になるので、ここでそれについて述べています。
    文法は以下のとおりです:
    

    
        <!--#set var="name" value="Rich" -->

    

    
    このように単純に文字どおりに設定することに加え、
    環境変数や上記の変数
    (例えば LAST_MODIFIED のような)
    を含む他のあらゆる変数を値を設定するのに使用することができます。
    変数名の前にドル記号 ($) を使用することで、
    それがリテラル文字列ではなくて変数であることを示します。
    

    
        <!--#set var="modified" value="$LAST_MODIFIED" -->

    

    
    ドル記号 ($) を文字として変数の値に入れるには、
    バックスラッシュによってドル記号をエスケープする必要があります。
    

    
        <!--#set var="cost" value="\$100" -->

    

    
    最後になりますが、長い文字列の中に変数を置きたい場合で、
    変数名が他の文字とぶつかる可能性があり、
    それらの文字について混乱してしまう場合、この混乱を取り除くため、
    変数名を中括弧で囲むことができます
    (これについての良い例を示すのは難しいのですが、
    おそらく分かっていただけるでしょう)。
    
    

    
        <!--#set var="date" value="${DATE_LOCAL}_${DATE_GMT}" -->

    



    条件式
    


    
    さて、変数を持っていて、
    それらの値を設定して比較することができるのですから、
    条件を表すためにそれらを使用することができます。これにより
    SSI はある種の小さなプログラミング言語になっています。
    mod_include は条件を表現するために if,
    elif, else, endif
    構造を提供しています。これによって、
    一つの実際のページから複数の論理ページを効果的に生成することができます。
    

    
    条件構造は以下のとおりです:
    

    
    <!--#if expr="test_condition" -->
    
    <!--#elif expr="test_condition" -->
    
    <!--#else -->
    
    <!--#endif -->

    

    
    test_condition
    はあらゆる種類の論理的比較をすることができます。
    値を比較したり、その値が ``真'' かどうかを評価します
    (空でないなら与えられた文字列は真です)。
    利用可能な比較演算子の全てのリストについては、
    mod_include ドキュメンテーションを参照してください。
    ここでは、この構造をどう使用するかの例をいくつか示します。
    

    
    設定ファイルで次の行を記述します:
    

    
        BrowserMatchNoCase macintosh Mac
    
        BrowserMatchNoCase MSIE InternetExplorer

    

    
    これはクライアントが Macintosh
    上でインターネットエクスプローラが動いている場合、環境変数
    ``Mac'' と ``InternetExplorer'' を真と設定します。
    

    
    次に、SSI が可能になったドキュメントで以下を行ないます:
    
    

    
        <!--#if expr="${Mac} && ${InternetExplorer}" -->
    
        Apologetic text goes here
    
        <!--#else -->
    
        Cool JavaScript code goes here
    
        <!--#endif -->

    

    
    Mac 上の IE に対して何か思うところがあるわけでありません。
    他では実行できているいくつかの JavaScript を Mac 上の IE
    で実行させるのに、先週数時間苦労したというだけのことです。
    上の例はその暫定的な対処方法です。
    

    
    他のどんな変数 (あなたが定義するもの、
    または普通の環境変数のいずれか) も、条件文に使用することができます。
    Apache は SetEnvIf ディレクティブや他の関連
    ディレクティブを使用して環境変数を設定することができます。
    この機能により、CGI
    に頼ることなくかなり複雑な動的なことをさせることができます。
    


    top
    

    

    終わりに
    

    
    SSI は確かに CGI
    や動的なウェブページを生成する他の技術に代わるものではありません。
    しかし、たくさんの余分な作業をせずに、
    少量の動的なコンテンツを加えるにはすぐれた方法です。

    Control de Acceso
    

    

    Idiomas disponibles:  en  |
 es  |
 fr 
    

    

    
    El control de acceso, hace referencia a todos los medios que proporcionan
        una forma de controlar el acceso a cualquier recurso. Esta parte está
        separada de autenticación y autorización.
    

    


    top
    

    

    Módulos y Directivas relacionados
    

    
    El control de acceso puede efectuarse mediante diferentes módulos. Los 
    más importantes de éstos son mod_authz_core y
    mod_authz_host. También se habla en este documento de
    el control de acceso usando el módulo mod_rewrite.
    


    top
    

    

    Control de Acceso por host
    
    
    
    Si lo que se quiere es restringir algunas zonas del sitio web, basándonos
    en la dirección del visitante, esto puede ser realizado de manera 
    fácil con el módulo mod_authz_host.
    
    

    
    La directiva Require
    proporciona una variedad de diferentes maneras de permitir o denegar el acceso a los recursos. Además puede ser usada junto con las directivas:RequireAll, RequireAny, y RequireNone, estos requerimientos pueden
    ser combinados de forma compleja y arbitraria, para cumplir cualquiera que
    sean tus políticas de acceso.
    

    
    
    Las directivas Allow,
    Deny, y
    Order,
    proporcionadas por mod_access_compat, están obsoletas y
    serán quitadas en futuras versiones. Deberá evitar su uso, y también
    los tutoriales desactualizaos que recomienden su uso.
    
    

    
    El uso de estas directivas es:
    

 
    
    Require host address 
    
Require ip ip.address
    
    


    
    En la primera línea, address es el FQDN de un nombre de 
    dominio (o un nombre parcial del dominio); puede proporcionar múltiples
    direcciones o nombres de dominio, si se desea.
    
    

    
    En la segunda línea, ip.address es la dirección IP, una
    dirección IP parcial, una red con su máscara, o una especificación red/nnn 
    CIDR. Pueden usarse tanto IPV4 como IPV6.
    

    
    Consulte también la 
    documentación de mod_authz_host  para otros ejemplos de esta sintaxis.
    
    

    
    Puede ser insertado not para negar un requisito en particular.
    Note que, ya que not es una negación de un valor, no puede ser 
    usado por si solo para permitir o denegar una petición, como not true
    que no contituye ser false. En consecuencia, para denegar una 
    visita usando una negación, el bloque debe tener un elemento que se evalúa como
    verdadero o falso. Por ejemplo, si tienes a alguien espameandote tu tablón de 
    mensajes, y tu quieres evitar que entren o dejarlos fuera, puedes realizar
    lo siguiente:
    
    

    
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>
    


    
    Los visitantes que vengan desde la IP que se configura (10.252.46.165)
    no tendrán acceso al contenido que cubre esta directiva. Si en cambio, lo que se 
    tiene es el nombre de la máquina, en vez de la IP, podrás usar:
    

    
    Require not host host.example.com
    
    


    
    Y, Si lo que se quiere es bloquear el acceso desde dominio especifico, 
        podrás especificar parte de una dirección o nombre de dominio:
    

    
    Require not ip 192.168.205
Require not host phishers.example.com moreidiots.example
Require not host gov
    


    
    Uso de las directivas RequireAll, RequireAny, y RequireNone pueden ser usadas
    para forzar requisitos más complejos.
    


    top
    

    

    Control de acceso por variables arbitrarias.
    

    
    Haciendo el uso de <If>,
    puedes permitir o denegar el acceso basado en variables de entrono arbitrarias
    o en los valores de las cabeceras de las peticiones. Por ejemplo para denegar 
    el acceso basándonos en el "user-agent" (tipo de navegador así como Sistema Operativo)
    puede que hagamos lo siguiente:
    
    

    
    <If "%{HTTP_USER_AGENT} == 'BadBot'">
    Require all denied
</If>
    


    
    Usando la sintaxis de Require
    expr , esto también puede ser escrito de la siguiente forma:
    
    


    
    Require expr %{HTTP_USER_AGENT} != 'BadBot'
    


    
    Advertencia:
    
    
    El control de acceso por User-Agent es una técnica poco fiable,
    ya que la cabecera de User-Agent puede ser modificada y establecerse 
    al antojo del usuario.
    
    
    

    
    Vea también la página de  expresiones
    para una mayor aclaración de que sintaxis tienen las expresiones y que
    variables están disponibles.
    


    top
    

    

    Control de acceso con mod_rewrite
    

    
    El flag [F] de RewriteRule causa una respuesta 403 Forbidden
    para ser enviada. USando esto, podrá denegar el acceso a recursos basándose
    en criterio arbitrario.
    

    
    Por ejemplo, si lo que desea es bloquear un recurso entre las 8pm y las 
        7am, podrá hacerlo usando mod_rewrite:
    

    
    RewriteEngine On
RewriteCond "%{TIME_HOUR}" ">=20" [OR]
RewriteCond "%{TIME_HOUR}" "<07"
RewriteRule "^/fridge"     "-"       [F]
    


    
    Esto devolverá una respuesta de error 403 Forbidden para cualquier  petición 
    después de las 8pm y antes de las 7am. Esta técnica puede ser usada para cualquier 
    criterio que desee usar. También puede redireccionar, o incluso reescribir estas 
    peticiones, si se prefiere ese enfoque.
    
    

    
    La directiva <If>,
     añadida en la 2.4, sustituye muchas cosas que mod_rewrite
     tradicionalmente solía hacer, y deberá comprobar estas antes de recurrir a 
    
    


    top
    

    

    Más información
    

    
    El motor de expresiones le da una gran
    capacidad de poder para hacer una gran variedad de cosas basadas en 
    las variables arbitrarias del servidor, y debe consultar este 
    documento para más detalles.
    

    
    También, deberá leer la documentación de mod_authz_core
    para ejemplos de combinaciones de múltiples requisitos de acceso y especificar
    cómo interactúan.

    Kimlik Doğrulama istediğiniz kişileri teyid etme işlemidir.
      Yetkilendirme ise kişilerin nereye gireceklerine ve hangi bilgiye
      ulaşacaklarına müsaade edilmesi işlemidir.
    

    
    Genel erişim denetimi için Erişim Denetimi
      Nasıl belgesine bakınız.

    İlgili modüller ve Yönergeler
    

    
    Kimlik Doğrulama ve yetkilendirme işlemi ile ilgili üç tür modül
    vardır. Genellikle her bir gruptan en az bir modül seçeceksiniz.
    

    

    
    Bu modüllere ek olarak, mod_authn_core ve
    mod_authz_core modülleri bulunur. Bu modüller
    yetkilendirme modüllerinin çekirdeğini oluşturan temel yönergeleri
    gerçekler.
    

    
    mod_authnz_ldap modülü kimlik doğrulama ve
    yetkilendirme işlemlerinin ikisini birden gerçekleştirir.
    mod_authz_host modülü bu işlemleri sunucu adına, IP
    adresine ve isteğin karekteristiğine bağlı olarak gerçekleştirir.
    Ancak kimlik doğrulama sisteminin bir parçası değildir.
    mod_access ile geriye uyumluluk için
    mod_access_compat diye bir modül daha vardır.
    

    
    Muhtemelen göz atmak isteyeceğiniz Erişim
    Denetimi nasıl belgesi, sunucuya erişimlerin çeşitli yollarından
    bahsetmektedir.

    Giriş
    
    
    Sitenizde sadece küçük bir grup insana hitap eden ya da hassas
    bilgileriniz varsa, bu makaledeki teknikleri kullanarak dilediğiniz
    kişilerin sadece dilediğiniz sayfaları görüntülemesini
    sağlayabilirsiniz.
    

    
    Bu makale sitenizin bazı parçalarını korumak için kullanacağınız
    "standart" yolları içermektedir.
    

    
    Bilginize:
    
      
    Eğer bilgileriniz gerçekten gizliliğe ihtiyaç duyuyorsa kimlik
      doğrulamasına ilaveten mod_ssl modülünü de
      kullanabilirsiniz.
    
    
    

  
    top
    

    

    Ön gereksinimler
    
    
    
    Bu makalede bahsi geçen yönergeler ya ana sunucu yapılandırma
    dosyasında (genellikle <Directory> bölümünde) ya da dizin içi
    yapılandırma dosyalarında (.htaccess dosyaları)
    bulunmak zorundadır.
    

    
    Eğer .htaccess dosyalarını kullanmayı
    tasarlıyorsanız, kimlik doğrulama yönergelerine bu dosyaların içine
    koymaya izin veren sunucu yapılandırmasına ihtiyacınız olacaktır.
    Bunun için, dizin içi yapılandırma dosyalarının içine hangi
    yönergelerin konacağını belirleyen AllowOverride yönergesi kullanılır.
    

    
    Kimlik doğrulamadan sözettiğimize göre, aşağıda gösterilen
    şekilde bir AllowOverride yönergesine ihtiyacınız olacaktır:
    

    
    AllowOverride AuthConfig
    


    
    Yönergeleri doğrudan ana sunucunun yapılandırma dosyasına
    koyacaksanız bu dosyaya yazma izniniz olmalıdır.
    

    
    Bazı dosyaların nerede saklandığını bilmek için sunucunun dizin
    yapısı hakkında biraz bilgi sahibi olmanız gerekmektedir. Bu çok da
    zor olmamakla birlikte bu noktaya gelindiğinde konuyu
    netleştireceğiz.
    

    
    Ayrıca mod_authn_core ve
    mod_authz_core modülleri ya httpd
    çalıştırılabilirinin içinde derlenmiş olmalı ya da
    httpd.conf yapılandırma dosyası ile yüklenmelidir. Bu
    iki modül HTTP sunucusunda kimlik doğrulama ve yetkilendirme
    kullanımı ve yapılandırması için büyük öneme sahip temel yönergeleri
    ve işlevselliği sağlar.
    

  
    top
    

    

    Çalışmaya Başlama
    
    
    Burada, sunucu üzerindeki bir dizini parolayla korumak için
    gereken temel bilgiler verilecektir.
    

    
    İlk olarak bir parola dosyası oluşturmalısınız. Bunu nasıl
    yapacağınız, özellikle, seçtiğiniz kimlik doğrulayıcıya göre
    değişiklik gösterir. Bunun üzerinde ileride daha fazla duracağız.
    Başlangıç için parolaları bir metin dosyasında tutacağız.
    

    
    Bu dosya belge kök dizini altında olmamalıdır. Böylece başkaları
    parola dosyasını indiremezler. Örneğin belgeleriniz
    /usr/local/apache/htdocs üzerinden sunuluyorsa parola
    dosyanızı /usr/local/apache/passwd dizininde
    tutabilirsiniz.
    

    
    Dosyayı oluşturmak için Apache ile gelen
    htpasswd uygulamasını kullanacağız. Bu uygulama
    Apache'nin kurulumunda belirtilen  bin dizininde
    bulunur. Eğer Apache'yi üçüncü parti paketlerden  kurduysanız,
    çalıştırılabilir dosyaların bulunduğu yollar üzerinde olmalıdır.
    

    
    Bir dosya oluşturmak için şunları yazın:
    

    
    
      htpasswd -c /usr/local/apache/passwd/passwords umut
    
    

    
    htpasswd size parola soracaktır arkasından da
    teyit etmek için parolayı tekrar girmenizi isteyecektir:
    

    
    
      # htpasswd -c /usr/local/apache/passwd/passwords umut
    
      New password: parolam
    
      Re-type new password: parolam
    
      Adding password for user umut
    
    

    
    Eğer htpasswd normal yollar üzerinde değilse
    çalıştırmak için dosyanın bulunduğu tam yeri belirtmeniz
    gerekecektir. Dosyanın öntanımlı kurulum yeri:
    /usr/local/apache2/bin/htpasswd
    

    
    Bundan sonra, sunucuyu, parola sorması için ve kimlerin erişim
    izni olacağını belirlemek için yapılandıracaksınız. Bu işlemi
    httpd.confdosyasını düzenleyerek ya da bir
    .htaccess dosyası kullanarak yapabilirsiniz. Örneğin,
    /usr/local/apache/htdocs/secret dizinini korumayı
    amaçlıyorsanız, şu yönergeleri kullanabilirsiniz. Bu yönergeleri
    /usr/local/apache/htdocs/secret/.htaccess dosyası içine
    veya httpd.conf içindeki <Directory
    "/usr/local/apache/htdocs/secret"> bölümüne koyabilirsiniz.
    

    
    AuthType Basic
AuthName "Gizli Dosyalar"
# (Aşağıdaki satırın kullanımı isteğe bağlıdır)
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
Require user umut
    


    
    Bu yönergeleri tek tek inceleyelim.
    AuthType yönergesi
    kullanıcının kimliğini doğrulamakta kullanılacak yöntemi seçer. En
    çok kullanılan yöntem Basic'tir ve bu yöntem
    mod_auth_basic modülüyle gerçeklenmiştir. Temel
    (Basic) kimlik doğrulamasıyla gönderilen parolanın
    şifrelenmeyeceğini unutmayın. Bu yöntem, bu sebepten dolayı
    mod_ssl eşliğinde kullanılmadığı sürece yüksek
    hassasiyete sahip bilgiler için kullanılmamalıdır. Apache bir başka
    kimlik doğrulama yöntemini daha destekler: AuthType
    Digest. Bu yöntem mod_auth_digest tarafından
    gerçeklenmişti ve çok daha güvenli olacağı düşünülmüştü. Bu artık
    geçerliliğini yitirdiğinden bağlantının bundan böyle
    mod_ssl ile şifrelenmesi gerekmektedir.
    

    
    AuthName yönergesi
    ile kimlik doğrulamada kullanılacak Saha da
    belirtilebilir. Saha kullanımının, başlıca iki işlevi vardır.
    Birincisi, istemci sıklıkla bu bilgiyi kullanıcıya parola diyalog
    kutusunun bir parçası olarak sunar. İkincisi, belirtilen kimlik
    doğrulamalı alan için gönderilecek parolayı belirlerken istemci
    tarafından kullanılır.
    

    
    Örneğin, bir istemcinin "Gizli Dosyalar" alanında
    kimliği doğrulanmış olsun. Aynı sunucu üzerinde "Gizli
    Dosyalar" Sahası olarak belirlenmiş alanlarda aynı parola
    özdevinimli olarak yinelenecektir. Böylece parola bir kere girilerek
    aynı Sahayı paylaşan çok sayıda kısıtlanmış alana ulaşırken oluşacak
    gecikmeden kullanıcı korunmuş olur. Güvenlik gerekçelerinden dolayı,
    her sunucu adı değiştirilişinde istemcinin parolayı yeniden sorması
    gerekir.
    

    
    AuthBasicProvider
    yönergesinin öntanımlı değeri file olduğundan, bu
    durumda, bu yönergenin kullanımı isteğe bağlıdır. Ancak, eğer kimlik
    doğrulaması için  mod_authn_dbm ya da
    mod_authn_dbd gibi farklı bir kaynak seçecekseniz
    bu yönergeyi kullanmanız gerekecektir.
    

    
    AuthUserFile
    yönergesi htpasswd ile oluşturduğumuz parola
    dosyasının yerini belirtmek için kullanılır. Eğer çok sayıda
    kullanıcınız varsa her bir kullanıcıyı her kimlik doğrulama isteği
    için kimlik bilgilerini bir metin dosyasında aramak gayet yavaş
    olacaktır. Apache, kullanıcı bilgilerini hızlı bir veritabanı
    dosyasında depolama özelliğine de sahiptir. Bu amaçla,
    mod_authn_dbm modülünün
    AuthDBMUserFile
    yönergesi kullanılabilir. Bu dosyalar dbmmanage ve
    htdbm programı ile oluşturulabilir ve değiştirilebilir.
    Üçüncü parti modüllerinde çok sayıda
    başka kimlik doğrulama türü de vardır.
    

    
    Son olarak Require
    yönergesi, sunucunun bu bölgesine erişimine izin verilen
    kullanıcıları ayarlama işleminin kimlik doğrulamasıyla ilgili
    kısmını sağlar. Bir sonraki bölümde Require yönergesini kullanmanın
    çeşitli yoları üzerinde duracağız.
    
  
    top
    

    

    Birden çok kişiye izin vermek
    
    
    
    Yukarıdaki yönergelerle bir dizinde sadece bir kişiye
    (umut adlı kullanıcıya) izin verir. Çoğunlukla birden
    çok kişiye izin verilmesi istenir. Bu durumda AuthGroupFile yönergesi
    devreye girer.
    

    
    Eğer birden çok kişiye izin vermek istiyorsanız içinde kullanıcı
    isimlerinin olduğu bir grup dosyası oluşturmalısınız. Bu dosyanın
    biçemi gayet basittir ve bunu herhangi bir metin düzenleyici ile
    oluşturabilirsiniz. Bu dosyanın içeriği aşağıdaki gibi
    görünecektir:
    

    
    
     GroupName: umut samet engin kubilay
    
    

    
    Dosya, sadece, boşluklarla birbirinden ayrılmış gurup üyelerinin
    isimlerinden oluşan uzun bir liste içerir.
    

    
    Varolan parola dosyasına bir kullanıcı eklemek için şunu
    yazın:
    

    
    
      htpasswd /usr/local/apache/passwd/passwords birey
    
    

    
    Evvelce almış olduğunuz yanıtı yine alacaksınız ama bu sefer yeni
    bir dosya oluşturulmak yerine var olan bir dosyaya eklenecektir.
    (Yeni bir parola dosyası oluşturmak için -c seçeneği
    kullanılır).
    

    
    Şimdi, .htaccess dosyanızı veya
    <Directory> bölümünüzü
    aşağıda görüldüğü şekilde değiştirebilirsiniz:
    

    
    AuthType Basic
AuthName "Davete Binaen"
# Satır isteğe bağlıdır:
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
AuthGroupFile "/usr/local/apache/passwd/groups"
Require group Grupismi
    


    
    Artık, Grupismi gurubunda listelenmiş ve
    password dosyasında kaydı olan kişiye, parolayı doğru
    yazdığı takdirde izin verilecektir.
    

    
    Çoklu kullanıcıya izin veren biraz daha az kullanılan başka bir
    yol daha mevcuttur. Bir gurup dosyası oluşturmaktansa, şu yönergeyi
    kullanabilirsiniz:
    

    
    Require valid-user
    


    
    Require user umut satırı ile parola dosyasında

    Olası Sorunlar
    
    
    Temel kimlik doğrulama yolu belirtildiği için, sunucuya
    yaptığınız her belge istediğinde kullanıcı adınızın ve parolanızın
    doğrulanması gerekir. Hatta aynı sayfayı yeniden yüklerken ya da
    sayfadaki her bir resim için bu yapılmalıdır (şayet korunmakta olan
    bir dizinden geliyorsa). Bu işlem hızı azaltacaktır. Yavaşlama
    miktarı parola dosyanızın büyüklüğü ile orantılı olacaktır, çünkü bu
    işlem sırasında dosya açılacak ve kullanıcıların arasında isminiz
    bulunana kadar liste aşağı doğru taranacaktır. Bu işlem sayfa her
    yüklenişinde tekrar edilecektir.
    

    
    Buradan çıkacak sonuç, bir parola dosyasına konulan kullanıcı
    sayısında bir üst sınır olması gerekliliğidir. Bu sınır sunucunuzun
    başarımına bağlı olarak değişiklik gösterir. Bir kaç yüz kayıtın
    üstünde giriş yaptığınızda hız düşüşünü gözlemlebilirsiniz İşte bu
    anda kimlik doğrulama için başka bir yöntem aramaya başlarsınız.

    Diğer parola depolama yöntemleri
    
    
    
    Parolaları basit bir metin dosyasında depolamak yukarıda
    bahsedilen sorunlara yol açtığından parolaları başka bir yerde
    depolamayı düşünebilirsiniz; örneğin bir veritabanında.
    

    
    mod_authn_dbm ve mod_authn_dbd
    modülleri bunu mümkün kılan iki modüldür. Depolama yönemi olarak
    AuthBasicProvider file yerine, dbm
    veya dbd kullanabilirsiniz.
    

    
    Bir metin dosyası yerine bir dbm dosyası kullanım örneği:
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider dbm
    AuthDBMUserFile "/www/passwords/passwd.dbm"
    Require valid-user
</Directory>
    


    
    Başka seçenekler de mümkündür. Ayrınılar için
    mod_authn_dbm belgesine başvurun.

    Birden çok tedarikçi kullanmak
    
    
    
    Kimlik doğrulama ve yetkilendirme mimarisine dayalı yeni
    tedarikçiyi kullanarak tek bir yetkilendirme ya da kimlik doğrulama
    yöntemine kilitlenip kalmayacaksınız. Aslında birden çok tedarikçi
    ihtiyacınıza cevap vermek için bir arada kullanılabilir. Aşağıdaki
    örnekte dosya ve LDAP tabanlı kimlik doğrulama tedarikçileri bir
    arada kullanılmıştır.
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file ldap
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    Require valid-user
</Directory>
    


    
    Bu örnekte dosya tedarikçisi, ilk olarak kullanıcının kimliğini
    doğrulamaya teşebbüs edecektir. Kullanıcının kimliği
    doğrulanamıyorsa LDAP tedarikçisi çağırılır. Eğer kurumunuz birden
    çok kimlik doğrulama tedarikçisini yürürlüğe koyuyorsa bu, kimlik
    doğrulama faaliyet alanının genişletilmesini sağlar. Diğer kimlik
    kanıtlama ve yetkilendirme senaryoları tek bir kimlik doğrulaması
    ile birden fazla yetkilendirme türüne izin verebilir.
    

    
    Çok sayıda kimlik doğrulama tedarikçisi uygulamaya konulabileceği
    gibi, çok sayıda yetkilendirme yöntemi de kullanılabilir. Bu örnekte
    dosya için hem dosyalı hem de LDAP grup kimlik doğrulaması
    kullanılmıştır.
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    AuthGroupFile "/usr/local/apache/passwd/groups"
    Require group GroupName
    Require ldap-group cn=mygroup,o=yourorg
</Directory>
    


    
    Kimlik doğrulama konusunu biraz daha genişletirsek, <RequireAll> ve
    <RequireAny> gibi yetkilendirme taşıyıcısı
    yönergelerle hangi iznin hangi sırayla uygulanacağını
    belirlenebilir. Yetkilendirme Taşıyıcıları bölümünde bunun bir uygulama
    örneğini görebilirsiniz.

    Yetkilendirmenin biraz ötesi
    
    
    Tek bir veri deposundan yapılacak tek bir sınamadan çok daha
    esnek kimlik doğrulaması yapılabilir. Sıralama, mantık ve hangi
    kimlik doğrulamasının kullanılacağını seçmek mümkündür.
    

    
    Mantık ve sıralamanın uygulanması
    
      
      
    Yetkilendirmenin hangi sırayla uygulanacağı ve nasıl
      denetleneceği geçmişte biraz gizemli bir konuydu. Apache 2.2'de,
      tedarikçi tabanlı kimlik doğrulamasının devreye girmesiyle asıl
      kimlik doğrulama işlemini yetkilendirme ve destek işlevselliğinden
      ayırmak mümkün oldu. Bunun faydalarından birisi de kimlik
      doğrulama tedarikçilerinin yapılandırılabilmesi ve auth modülünün
      kendi yükleme sırasından bağımsız olarak özel bir sırayla
      çağrılabilmesidir. Bu tedarikçi tabanlı mekanizmanın aynısı
      yetkilendirmeye de getirilmiştir. Bunun anlamı Require yönergesinde hangi
      izin yönteminin kullanılması gerektiğinin belirtmesinin yanında
      hangi sırayla çağırılacaklarının da belirlenebildiğidir. Çok
      sayıda yetkilendirme yöntemi kullanıldığında, bunlar, Require yönergelerinin
      yapılandırma dosyasında göründükleri sıra ile çağırılır.
    

      
    <RequireAll> ve <RequireAny> gibi yetkilendirme
      taşıyıcısı yönergelerin devreye girmesiyle yetkilendirme
      yöntemlerinin ne zaman çağırılacağı ve çağırıldığında ve erişime
      izin verirken hangi kuralların uygulanacağı konusunda denetim
      yapılandırmanın eline geçmektedir. Karmaşık yetkilendime mantığını
      ifade etmek için kullanılan bir örneği görmek için
      Yetkilendirme
      Taşıyıcıları bölümüne bakınız.
    

      
    Öntanımlı olarak tüm 
      Require yönergeleri, <RequireAny>
      taşıyıcı yönergesinin içine konur. Başka bir deyişle eğer
      belirtilen kimlik doğrulama yöntemlerinden herhangi biri başarılı
      olursa yetkilendirme de sağlanmış olur.
    

    

    
    Erişim denetimi için yetkilendirme tedarikçilerinin
      kullanımı
    
      
      
    Kullanıcı adı ve parolasına göre kimlik doğrulama hikayenin
      sadece bir bölümüdür. Sıklıkla insanlara kim olduklarına göre
      değil birşeylere dayanarak izin vermek istersiniz. Örneğin nereden
      geldikleri gibi.
    

      
    all, env, host ve
      ip gibi yetkilendirme tedarikçileri ile, bir belgenin
      istendiği makinenin IP adresi veya konak ismi gibi bazı özelliklerine
      dayalı olarak erişime izin verip vermeyeceğinizi belirtebilirsiniz.
    

      
    Bu tedarikçilerin kullanımı Require yönergesinde açıklanmıştır. Bu yönergeler,
      isteklerin işlenmesi sırasında yetkilendirme aşamasında
      çağırılacak yetkilendirme tedarikçilerini kayda geçirir. Örneğin:
      
    

      
    Require ip adres
      
    


      
    Burada, adres bir IP adresidir (veya kısmi bir IP
        addresidir)
    

      
    Require host alan_adı
      
    


      
    Burada, alan_adı bir tam nitelikli alan adıdır
      (ya da kısmi alan adıdır); gerekirse çok sayıda alan adı veya IP
      adresi de belirtilebilir.
    

      
    Örneğin, yorum alanını gereksiz iletilerle dolduran birini uzak
      tutmak istediğinizi varsayalım. Bu kişiyi uzak tutmak için şunları
      yapabilirsiniz:
    

        
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>
    


      
    Bu adresden gelen ziyaretçiler bu yönergedeki içeriği
      göremeyeceklerdir. Bunun yerine, elinizde IP adresi değil de
      makine adı varsa şunu kullanabilirsiniz:
    

        
    <RequireAll>
    Require all granted
    Require not host host.example.com
</RequireAll>
    


      
    Eğer alan adının tamanıdan gelecek olan bütün erişimleri
      engellemek isterseniz adresin ya da alan adının bir parçasını
      belirtin:
    

        
    <RequireAll>
    Require all granted
    Require not ip 192.168.205
    Require not host phishers.example.com moreidiots.example
    Require not host ke
</RequireAll>
    


        
    <RequireAll> yönergesini çok sayıda
        <Require> yönergesi ile birlikte kullanarak,
        sadece not ile olumsuzlanan tüm koşulları gerçekleyen
        bağlantılara erişim verilir. Başka bir deyişle, olumsuzlanan koşulları
        gerçeklemeyen bağlantıların erişimi engellenir.
    

    

    
    Erişim denetimi ve geriye uyumluluk
    
      
      
    Kimlik doğrulama için tedarik tabanlı mekanizma kullanımının
      yan etkilerinden birisi,
      Order,
      Allow,
      Deny ve
      Satisfy erişim
      denetim yönergelerine artık ihtiyaç duyulmamasıdır. Ancak eski
      yapılandırmalarla uyumluluğu sağlamak için bu yönergeler
      mod_access_compat modülüne taşınmıştır.
    

      
    Note
    
        
    mod_access_compat ile sağlanan yönergelerin
        kullanımı artık önerilmemekte, mod_authz_host
        modülündeki yönergeler önerilmektedir. Order, Allow veya Deny ile
        Require gibi daha yeni
        olanlarının yenilerle karışık kullanımı teknik olarak mümkünse de
        önerilmemektedir. mod_access_compat modülü, 2.4
        yükseltmesini kolaylaştırmak için sadece eski yönergeleri içeren
        yapılandırmaları desteklemek üzere oluşturulmuştur.  Daha ayrıntılı
        bilgi için yükseltme belgesine bakınız.

    Kimlik Doğrulama Arabelleği

    Introduction
    
 
    Related ModulesRelated Directives
    

    
    This article deals with Server Side Includes, usually called
    simply SSI. In this article, I'll talk about configuring your
    server to permit SSI, and introduce some basic SSI techniques
    for adding dynamic content to your existing HTML pages.
    

    
    In the latter part of the article, we'll talk about some of
    the somewhat more advanced things that can be done with SSI,
    such as conditional statements in your SSI directives.

    What are SSI?
    

    
    SSI (Server Side Includes) are directives that are placed in
    HTML pages, and evaluated on the server while the pages are
    being served. They let you add dynamically generated content to
    an existing HTML page, without having to serve the entire page
    via a CGI program, or other dynamic technology.
    

    
    For example, you might place a directive into an existing HTML
    page, such as:
    

    
    
    <!--#echo var="DATE_LOCAL" -->
    
    

    
    And, when the page is served, this fragment will be evaluated and replaced with its value:

    The decision of when to use SSI, and when to have your page
    entirely generated by some program, is usually a matter of how
    much of the page is static, and how much needs to be
    recalculated every time the page is served. SSI is a great way
    to add small pieces of information, such as the current time - shown
    above.  But if a majority of your page is being generated at the time
    that it is served, you need to look for some other solution.
    

    top
    

    

    Configuring your server to permit SSI
    


    
    To permit SSI on your server, you must have the following
    directive either in your httpd.conf file, or in a
    .htaccess file:
    

    Options +Includes
    


    
    This tells Apache that you want to permit files to be parsed
    for SSI directives.  Note that most configurations contain
    multiple Options directives
    that can override each other.  You will probably need to apply the
    Options to the specific directory where you want SSI
    enabled in order to assure that it gets evaluated last.
    

    
    Not just any file is parsed for SSI directives. You have to
    tell Apache which files should be parsed. There are two ways to
    do this. You can tell Apache to parse any file with a
    particular file extension, such as .shtml, with
    the following directives:
    

    AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
    


    
    One disadvantage to this approach is that if you wanted to
    add SSI directives to an existing page, you would have to
    change the name of that page, and all links to that page, in
    order to give it a .shtml extension, so that those
    directives would be executed.
    

    
    The other method is to use the XBitHack directive:
    

    XBitHack on
    


    
    XBitHack
    tells Apache to parse files for SSI
    directives if they have the execute bit set. So, to add SSI
    directives to an existing page, rather than having to change
    the file name, you would just need to make the file executable
    using chmod.
    

    
        chmod +x pagename.html

    

    
    A brief comment about what not to do. You'll occasionally
    see people recommending that you just tell Apache to parse all
    .html files for SSI, so that you don't have to
    mess with .shtml file names. These folks have
    perhaps not heard about XBitHack. The thing to
    keep in mind is that, by doing this, you're requiring that
    Apache read through every single file that it sends out to
    clients, even if they don't contain any SSI directives. This
    can slow things down quite a bit, and is not a good idea.
    

    
    Of course, on Windows, there is no such thing as an execute
    bit to set, so that limits your options a little.
    

    
    In its default configuration, Apache does not send the last
    modified date or content length HTTP headers on SSI pages,
    because these values are difficult to calculate for dynamic
    content. This can prevent your document from being cached, and
    result in slower perceived client performance. There are two
    ways to solve this:
    

    
      
      
    1. Use the XBitHack Full configuration. This
      tells Apache to determine the last modified date by looking
      only at the date of the originally requested file, ignoring
      the modification date of any included files.
      2. 

      
    2. Use the directives provided by
      mod_expires to set an explicit expiration
      time on your files, thereby letting browsers and proxies
      know that it is acceptable to cache them.
      3.

    Basic SSI directives
    

    
    SSI directives have the following syntax:
    

    
        <!--#function attribute=value attribute=value ... -->

    

    
    It is formatted like an HTML comment, so if you don't have
    SSI correctly enabled, the browser will ignore it, but it will
    still be visible in the HTML source. If you have SSI correctly
    configured, the directive will be replaced with its
    results.
    

    
    The function can be one of a number of things, and we'll talk
    some more about most of these in the next installment of this
    series. For now, here are some examples of what you can do with
    SSI
    


    Today's date
    


    
        <!--#echo var="DATE_LOCAL" -->

    

    
    The echo function just spits out the value of a
    variable. There are a number of standard variables, which
    include the whole set of environment variables that are
    available to CGI programs. Also, you can define your own
    variables with the set function.
    

    
    If you don't like the format in which the date gets printed,
    you can use the config function, with a
    timefmt attribute, to modify that formatting.
    


    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        Today is <!--#echo var="DATE_LOCAL" -->

    



    Modification date of the file
    


    
        This document last modified <!--#flastmod file="index.html" -->

    

    
    This function is also subject to timefmt format
    configurations.
    



    Including the results of a CGI program
    

    
    This is one of the more common uses of SSI - to output the
    results of a CGI program, such as everybody's favorite, a ``hit
    counter.''
    


    
        <!--#include virtual="/cgi-bin/counter.pl" -->

    



    top
    

    

    Additional examples
    


    
    Following are some specific examples of things you can do in
    your HTML documents with SSI.
    


    When was this document
modified?
    

    
    Earlier, we mentioned that you could use SSI to inform the
    user when the document was most recently modified. However, the
    actual method for doing that was left somewhat in question. The
    following code, placed in your HTML document, will put such a
    time stamp on your page. Of course, you will have to have SSI
    correctly enabled, as discussed above.
    

    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        This file last modified <!--#flastmod file="ssi.shtml" -->

    

    
    Of course, you will need to replace the
    ssi.shtml with the actual name of the file that
    you're referring to. This can be inconvenient if you're just
    looking for a generic piece of code that you can paste into any
    file, so you probably want to use the
    LAST_MODIFIED variable instead:
    

    
        <!--#config timefmt="%D" -->
    
        This file last modified <!--#echo var="LAST_MODIFIED" -->

    

    
    For more details on the timefmt format, go to
    your favorite search site and look for strftime. The
    syntax is the same.
    



    Including a standard footer
    


    
    If you are managing any site that is more than a few pages,
    you may find that making changes to all those pages can be a
    real pain, particularly if you are trying to maintain some kind
    of standard look across all those pages.
    

    
    Using an include file for a header and/or a footer can
    reduce the burden of these updates. You just have to make one
    footer file, and then include it into each page with the
    include SSI command. The include
    function can determine what file to include with either the
    file attribute, or the virtual
    attribute. The file attribute is a file path,
    relative to the current directory. That means that it
    cannot be an absolute file path (starting with /), nor can it
    contain ../ as part of that path. The virtual
    attribute is probably more useful, and should specify a URL
    relative to the document being served. It can start with a /,
    but must be on the same server as the file being served.
    

    
        <!--#include virtual="/footer.html" -->

    

    
    I'll frequently combine the last two things, putting a
    LAST_MODIFIED directive inside a footer file to be
    included. SSI directives can be contained in the included file,
    and includes can be nested - that is, the included file can
    include another file, and so on.
    



    top
    

    

    What else can I config?
    


    
    In addition to being able to config the time
    format, you can also config two other things.
    

    
    Usually, when something goes wrong with your SSI directive,
    you get the message
    

    
        [an error occurred while processing this directive]

    

    
    If you want to change that message to something else, you
    can do so with the errmsg attribute to the
    config function:
    

    
        <!--#config errmsg="[It appears that you don't know how to use SSI]" -->

    

    
    Hopefully, end users will never see this message, because
    you will have resolved all the problems with your SSI
    directives before your site goes live. (Right?)
    

    
    And you can config the format in which file
    sizes are returned with the sizefmt attribute. You
    can specify bytes for a full count in bytes, or
    abbrev for an abbreviated number in Kb or Mb, as
    appropriate.

    Executing commands
    
    

    
    Here's something else that you can do with the exec
    function. You can actually have SSI execute a command using the
    shell (/bin/sh, to be precise - or the DOS shell,
    if you're on Win32). The following, for example, will give you
    a directory listing.
    

    
        <pre>
    
        <!--#exec cmd="ls" -->
    
        </pre>

    

    
    or, on Windows
    

    
        <pre>
    
        <!--#exec cmd="dir" -->
    
        </pre>

    

    
    You might notice some strange formatting with this directive
    on Windows, because the output from dir contains
    the string ``<dir>'' in it, which confuses
    browsers.
    

    
    Note that this feature is exceedingly dangerous, as it will
    execute whatever code happens to be embedded in the
    exec tag. If you have any situation where users
    can edit content on your web pages, such as with a
    ``guestbook'', for example, make sure that you have this
    feature disabled. You can allow SSI, but not the
    exec feature, with the IncludesNOEXEC
    argument to the Options directive.
    
    
    top
    

    

    Advanced SSI techniques
    


    
    In addition to spitting out content, Apache SSI gives you
    the option of setting variables, and using those variables in
    comparisons and conditionals.
    


    Setting variables
    

    
    Using the set directive, you can set variables
    for later use. We'll need this later in the discussion, so
    we'll talk about it here. The syntax of this is as follows:
    

    
        <!--#set var="name" value="Rich" -->

    

    
    In addition to merely setting values literally like that, you
    can use any other variable, including environment variables or the variables
    discussed above (like LAST_MODIFIED, for example) to
    give values to your variables. You will specify that something is
    a variable, rather than a literal string, by using the dollar sign
    ($) before the name of the variable.
    

    
     <!--#set var="modified" value="$LAST_MODIFIED" -->
    
    

    
    To put a literal dollar sign into the value of your
    variable, you need to escape the dollar sign with a
    backslash.
    

    
        <!--#set var="cost" value="\$100" -->

    

    
    Finally, if you want to put a variable in the midst of a
    longer string, and there's a chance that the name of the
    variable will run up against some other characters, and thus be
    confused with those characters, you can place the name of the
    variable in braces, to remove this confusion. (It's hard to
    come up with a really good example of this, but hopefully
    you'll get the point.)
    

    
        <!--#set var="date" value="${DATE_LOCAL}_${DATE_GMT}" -->

    



    Conditional expressions
    


    
    Now that we have variables, and are able to set and compare
    their values, we can use them to express conditionals. This
    lets SSI be a tiny programming language of sorts.
    mod_include provides an if,
    elif, else, endif
    structure for building conditional statements. This allows you
    to effectively generate multiple logical pages out of one
    actual page.
    

    
    The structure of this conditional construct is:
    

    
    <!--#if expr="test_condition" -->
    
    <!--#elif expr="test_condition" -->
    
    <!--#else -->
    
    <!--#endif -->

    

    
    A test_condition can be any sort of logical
    comparison - either comparing values to one another, or testing
    the ``truth'' of a particular value. (A given string is true if
    it is nonempty.) For a full list of the comparison operators
    available to you, see the mod_include
    documentation.
    
   
    
    For example, if you wish to customize the text on your web page
    based on the time of day, you could use the following recipe, placed
    in the HTML page:
    

    
    
    Good
    <!--#if expr="%{TIME_HOUR} <12" -->
    
    morning!
    
    <!--#else -->
    
    afternoon!
    
    <!--#endif -->
    
    
    

    
    Any other variable (either ones that you define, or normal
    environment variables) can be used in conditional statements.
    See Expressions in Apache HTTP Server for
    more information on the expression evaluation engine.
    

    
    With Apache's ability to set environment variables with the
    SetEnvIf directives, and other related directives,
    this functionality can let you do a wide variety of dynamic content
    on the server side without resorting a full web application.

    Conclusion
    

    
    SSI is certainly not a replacement for CGI, or other
    technologies used for generating dynamic web pages. But it is a
    great way to add small amounts of dynamic content to pages,
    without doing a lot of extra work.

  この 2 つのモジュールは認証モジュールに共通なコアディレクティブを
  実装しています。
    

  
    mod_authnz_ldap は認証プロバイダと承認プロバイダの
  両方の機能を持っています。
  mod_authz_host はホスト名、IP アドレスや
  リクエストの特徴に基づいたアクセス制御を行いますが、
  認証プロバイダのシステムの一部ではありません。
  mod_access との後方互換性のため、
  新しいモジュールの mod_access_compat があります。

    はじめに
    
    
    もし機密の情報や、ごくごく少数グループの人向けの情報を
    ウェブサイトに置くのであれば、この文書に書かれている
    テクニックを使うことで、そのページを見ている人たちが
    望みの人たちであることを確実にできるでしょう。
    

    
    この文書では、多くの人が採用するであろう、
    ウェブサイトの一部分を保護する「一般的な」
    方法についてカバーしています。
    

    
    注意
    
    
    データが本当に機密なのであれば、認証に加えてさらに
    mod_ssl を使うと良いでしょう。

    準備
    
    
    この文書で取り扱われるディレクティブは、
    メインサーバ設定ファイル (普通は 
    <Directory>
    セクション中) か、あるいはディレクトリ毎の設定ファイル 
    (.htaccess ファイル) かで用います。
    

    
    .htaccess ファイルを用いるのであれば、
    これらのファイルに認証用のディレクティブを置けるように
    サーバの設定をしないといけないでしょう。これは
    AllowOverride
    ディレクティブで可能になります。
    AllowOverride
    ディレクティブでは、ディレクトリ毎の設定ファイル中に置くことのできる
    ディレクティブを、もしあれば、指定します。
    

    
    認証について話を進めているので、次のような
    AllowOverride
    ディレクティブが必要になるでしょう。
    

    
    
      AllowOverride AuthConfig
    
    

    
    そうでなく、メインサーバ設定ファイルの中に
    直接置くのであれば、当然ながらそのファイルへの書き込み
    権限を持っていなければならないでしょう。
    

    
    また、どのファイルがどこに保存されているか知るために、
    サーバのディレクトリ構造について少し知っておく
    必要があるでしょう。
    これはそんなに難しくないので、この文書中で
    ディレクトリ構造について知っておく必要がある場面では、
    明らかになるようにします。
    

    
    mod_authn_core と mod_authz_core 
    の両方が httpd バイナリに静的に組み込み済みであるか、httpd.conf 
    設定ファイルで動的にロードされるかして、httpd に組み込まれていなければ
    なりません。これらの二つのモジュールは、設定ファイルのなかで非常に
    重要でウェブサーバの認証と承認で使用されるコアディレクティブと
    その機能を提供しています。

    動作させる
    
    
    では、サーバ上のあるディレクトリをパスワードで保護する
    基本手順を示します。
    

    
    まずはじめに、パスワードファイルを作ります。
    どの認証プロバイダを使うかによって、パスワードファイル生成の手順は
    大きく異なります。ここでの例では、手始めにテキストパスワードファイルを
    使います。
    

    
    このパスワードファイルは、ウェブからアクセスできる場所に
    置くべきではありません。他の人がパスワードファイルを
    ダウンロードできないようにするためです。例えば、
    /usr/local/apache/htdocs でドキュメントを
    提供しているのであれば、パスワードファイルは
    /usr/local/apache/passwd
    などに置いた方が良いでしょう。
    

    
    ファイルを作るためには、Apache 付属の htpasswd 
    を使います。このコマンドは Apache をどこにインストールしようとも、
    インストールディレクトリの bin 
    ディレクトリ以下に置かれます。サードバーティ製のパッケージで
    インストールした場合は、実行パスの中で見つかるでしょう。
    
    
    
    ファイルを作るには、次のようにタイプしてください。
    

    
    
      htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
    

    
    htpasswd は、パスワードを要求し、その後
    確認のためにもう一度入力するように要求してきます。
    

    
    
      # htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
      New password: mypassword
    
      Re-type new password: mypassword
    
      Adding password for user rbowen
    
    

    
    もし htpasswd がパスの中に入っていない場合は、
    もちろん、実行するためにプログラムまでのフルパスを
    タイプする必要があります。デフォルトのインストール状態であれば、
    /usr/local/apache/bin/htpasswd
    にプログラムが置かれています。
    

    
    次に、サーバがパスワードを要求するように設定して、
    どのユーザがアクセスを許されているかをサーバに知らせなければ
    なりません。 httpd.conf を編集するか
    .htaccess ファイルを使用するかで
    設定します。例えば、ディレクトリ
    /usr/local/apache/htdocs/secret
    を保護したい場合は、
    /usr/local/apache/htdocs/secret/.htaccess
    か httpd.conf 中の <Directory
    /usr/local/apache/htdocs/secret> セクションに
    配置して、次のディレクティブを使うことができます。
    

    
    
      AuthType Basic
    
      AuthName "Restricted Files"
    
      # (Following line optional)
    
      AuthBasicProvider file
    
      AuthUserFile /usr/local/apache/passwd/passwords
    
      Require user rbowen
    
    

    
    個々のディレクティブについて見てみましょう。
    AuthType
    ディレクティブはどういう認証方法でユーザの認証を行うかを
    選択します。最も一般的な方法は Basic
    で、これは mod_auth_basic
    で実装されています。しかしながら、
    これは気を付けるべき重要なポイントなのですが、
    Basic 認証はクライアントからサーバへ、
    パスワードを暗号化せずに送ります。ですからこの方法は、
    mod_ssl と組み合わせない状態では、
    特に機密性の高いデータに対しては用いるべきでは
    ありません。 Apache ではもう一つ別の認証方法:
    AuthType Digest をサポートしています。
    この方法は mod_auth_digest
    で実装されていて、もっと安全です。
    最近のクライアントは Digest
    認証をサポートしているようです。
    

    
    AuthName
    ディレクティブでは、認証に使う Realm (訳注: 領域)
    を設定します。Realm は大きく分けて二つの機能を提供します。
    一つ目は、クライアントがパスワードダイアログボックスの
    一部としてユーザにこの情報をよく提示する、というものです。
    二つ目には、クライアントが与えられた認証領域に対してどのパスワードを
    送信すれば良いのかを決定するために使われる、という機能です。
    

    
    例えば、"Restricted Files" 領域中で
    一度認証されれば、同一サーバ上で "Restricted Files"
    Realm としてマークされたどんな領域でも、クライアントは
    自動的に同じパスワードを使おうと試みます。
    このおかげで、複数の制限領域に同じ realm を共有させて、
    ユーザがパスワードを何度も要求される事態を
    防ぐことができます。もちろん、セキュリティ上の理由から、
    サーバのホスト名が変わればいつでも必ず、
    クライアントは再びパスワードを尋ねる必要があります。
    

    
    AuthBasicProvider
    はデフォルト値が file なので、今回の場合は無くても構いません。
    mod_authn_dbm や mod_authn_dbd
    といった他のモジュールを使う場合には必要になります。
    
    

    
    AuthUserFile
    ディレクティブは htpasswd で作った
    パスワードファイルへのパスを設定します。
    ユーザ数が多い場合は、リクエスト毎のユーザの認証のための
    プレーンテキストの探索が非常に遅くなることがあります。
    Apache ではユーザ情報を高速なデータベースファイルに
    保管することもできます。
    mod_authn_dbm モジュールが
    AuthDBMUserFile
    ディレクティブを提供します。これらのファイルは dbmmanage
    プログラムで作成したり操作したりできます。
    Apache 
    モジュールデータベース中にあるサードパーティー製の
    モジュールで、その他多くのタイプの認証オプションが
    利用可能です。
    

    
    最後に、Require
    ディレクティブが、サーバのこの領域にアクセスできるユーザを
    指定することによって、プロセスの承認部分を提供します。
    次のセクションでは、Require
    ディレクティブの様々な用法について述べます。
    

    top
    

    

    
複数の人が入れるようにする
    
    
    上記のディレクティブは、ただ一人 (具体的にはユーザ名
    rbowen の誰か) がディレクトリに
    入れるようにします。多くの場合は、複数の人が
    入れるようにしたいでしょう。ここで
    AuthGroupFile
    の登場です。
    

    
    もし複数の人が入れるようにしたいのであれば、
    グループに属するユーザの一覧の入っている、グループ名のついた
    グループファイルを作る必要があります。このファイルの
    書式はきわめて単純で、お好みのエディタで生成できます。
    ファイルの中身は次のようなものです。
    

   
    
     GroupName: rbowen dpitts sungo rshersey
   
    

    
    一行にスペース区切りで、グループに所属するメンバーの
    一覧をならべるだけです。
    

    
    既に存在するパスワードファイルにユーザを加える場合は、
    次のようにタイプしてください。
    

    
    
      htpasswd /usr/local/apache/passwd/passwords dpitts
    
    

    
    以前と同じ応答が返されますが、新しいファイルを
    作るのではなく、既にあるファイルに追加されています。
    (新しいパスワードファイルを作るには -c
    を使います。)
    

    
    ここで次のようにして .htaccess ファイルを
    修正する必要があります。
    

    
    
      AuthType Basic
    
      AuthName "By Invitation Only"
    
      # Optional line:
    
      AuthBasicProvider file
    
      AuthUserFile /usr/local/apache/passwd/passwords
    
      AuthGroupFile /usr/local/apache/passwd/groups
    
      Require group GroupName
    
    

    
    これで、グループ GroupName にリストされていて、
    password ファイルにエントリがある人は、
    正しいパスワードをタイプすれば入ることができるでしょう。
    

    
    もっと特定せずに複数のユーザが入れるようにする、
    もう一つの方法があります。グループファイルを作るのではなく、
    次のディレクティブを使えばできます。
    

    
    
      Require valid-user
    
    

    
    require user rbowen 行でなく、上記を使うと、
    パスワードファイルにリストされている人であれば誰でも
    許可されます。
    単にパスワードファイルをグループ毎に分けておくことで、
    グループのような振る舞いをさせることもできます。
    このアプローチの利点は、Apache は二つではなく、
    ただ一つのファイルだけを検査すればよいという点です。
    欠点は、たくさんのパスワードファイルを管理して、その中から
    AuthUserFile
    ディレクティブに正しいファイルを参照させなければならない点です。
    

    top
    

    

    起こりえる問題
    
    
    Basic 認証が指定されている場合は、
    サーバにドキュメントをリクエストする度に
    ユーザ名とパスワードを検査しなければなりません。
    これは同じページ、ページにある全ての画像を
    リロードする場合であっても該当します
     (もし画像も保護されたディレクトリから来るのであれば) 。
    予想される通り、これは動作を多少遅くします。
    遅くなる程度はパスワードファイルの大きさと比例しますが、
    これは、ファイルを開いてあなたの名前を発見するまで
    ユーザ名のリストを読まなければならないからです。
    そして、ページがロードされる度にこれを行わなければ
    なりません。
    

    
    結論としては、一つのパスワードファイルに置くことのできる
    ユーザ数には実質的な限界があります。
    この限界はサーバマシンの性能に依存して変わりますが、
    数百のエントリを越えたあたりから速度低下が見られると予期されています。
    その時は他の認証方法を考慮に入れた方が良いでしょう。
    

    top
    

    

    パスワードの保存形式を変える
    

    
    プレーンテキストでパスワードを保存する方法には上記の問題があり、
    データベースのような別の場所にパスワードを保存したいと思う
    かもしれません。
    

    
    mod_authn_dbm と mod_authn_dbd
    を使うと、それができるようになります。
    AuthBasicSource
    で file の代わりに、dbm あるいは dbd
    を格納形式として選べます。
    

    
    テキストファイルの代わりに dbm ファイルを選択する場合は、たとえば次のようにします。
    

    
    
    <Directory /www/docs/private>
    
    AuthName "Private"
    
    AuthType Basic
    
    AuthBasicProvider dbm
    
    AuthDBMUserFile /www/passwords/passwd.dbm
    
    Require valid-user
    
    </Directory>
    
    

    
    この他のオプションも存在します。詳細に関しては
    mod_authn_dbm のドキュメントをご覧ください。
    

    top
    

    

    複数のプロバイダを使用する
    

    
    認証承認アーキテクチャに基づいている新しいプロバイダを使うと、
    認証承認の方法をひとつに縛る必要がなくなります。
    いくつものプロバイダを組み合わせて、自分の望みの挙動にできます。
    次の例では file 認証プロバイダと ldap 認証プロバイダを
    組み合わせています。
    

    
    
    <Directory /www/docs/private>
    
    AuthName "Private"
    
    AuthType Basic
    
    AuthBasicProvider file ldap
    
    AuthUserFile /usr/local/apache/passwd/passwords
    
    AuthLDAPURL ldap://ldaphost/o=yourorg
    
    Require valid-user
    
    

    
    この例では、まず file プロバイダがユーザ認証を試みます。
    認証できなかった場合には、ldap プロバイダが呼び出されます。
    組織で複数の認証格納方法を使っている際などに、
    この方法を使って認証のスコープを拡大できます。
    もうひとつのシナリオは、ひとつの認証タイプと異なる承認を
    組み合わせる方法でしょう。たとえば、パスワードファイルで認証して、
    ldap ディレクトリで承認を行うといった場合です。
    

    
    認証プロバイダを複数実装できるように、承認方法も複数使用できます。
    この例では file グループ承認と ldap グループ承認を使っています。
    

    
    
    <Directory /www/docs/private>
    
    AuthName "Private"
    
    AuthType Basic
    
    AuthBasicProvider file
    
    AuthUserFile /usr/local/apache/passwd/passwords
    
    AuthLDAPURL ldap://ldaphost/o=yourorg
    AuthGroupFile /usr/local/apache/passwd/groups
    
    Require group GroupName
    
    Require ldap-group cn=mygroup,o=yourorg
    
    

    
    承認をより細かく制御したい場合は、
    <SatisfyAll> と
    <SatisfyOne> 
    ディレクティブを使って AND/OR ロジックで指定し、設定ファイルで
    承認の処理順番の制御ができるようになっています。
    これらのディレクティブをどのように使えるか、網羅した例をご覧ください。
    


    top
    

    

    単純な承認のその先
    

    
    承認の方法は、ひとつのデータソースを見て一回だけチェックするのと比べて、
    ずっと多彩な適用方法ができます。
    承認処理の適用順序や制御、選択ができるようになりました。
    

    
    AND/OR ロジックの適用と順序付け
    
        
    承認がどのような順序で適用されているか、また、それをどのように制御するかは、
        これまで混乱を招いていました。
        Apache 2.2 ではプロバイダベースの認証メカニズムが導入され、
        承認処理から認証処理とサポート機能とが切り分けられました。
        これによるひとつの効果として、
        認証モジュールのロード順やモジュール自体の順序に依存することなく、
        指定した順番で認証プロバイダが呼び出せるよう、
	設定できるようになりました。
        このプロバイダメカニズムは承認処理でも導入されています。
        つまり、Require
        ディレクティブは単にどの承認手法が使われるかを指定するだけではなく、
        それらの呼び出し順序も指定できるようになりました。
        複数の承認手法があるとき、その呼び出し順は、設定ファイルの
        Require ディレクティブ中で
        現れた順序と同じになります。
    

        
    追加で導入された
        <SatisfyAll>,
        <SatisfyOne>
        ディレクティブを使って、承認手法がいつ呼び出され、アクセスが許可された際に
        どの手続きが適用されるか指定することができます。
        たとえば、次の承認ブロックのロジックを見てみましょう:
    

        
    
          # if ((user == "John") ||
    
          #    ((Group == "admin")
    
          #     && (ldap-group <ldap-object> contains auth'ed_user)
    
          #     && ((ldap-attribute dept == "sales")
    
          #         || (file-group contains auth'ed_user))))
    
          # then
    
          #   auth_granted
    
          # else
    
          #   auth_denied
    
          #
    
          <Directory /www/mydocs>
    
          
            Authname ...
    
            AuthBasicProvider ...
    
            ...
    
            Require user John
    
            <SatisfyAll>
    
            
              Require Group admins
    
              Require ldap-group cn=mygroup,o=foo
    
              <SatisfyOne>
    
              
                Require ldap-attribute dept="sales"
    
                Require file-group
    
                  
              </SatisfyOne>
    
                
            </SatisfyAll>
    
              
          </Directory>
        
    

        
    デフォルトでは Require
        ディレクティブは OR 操作として扱われます。つまり、もし指定した承認手法の
        ひとつでも合格すれば、承認されます。
        Require ディレクティブのセットを
        ひとつの <SatisfyAll>
        ブロックで囲むとAND 操作となり、全ての承認手法で合格しなければ許可されません。
    

    

    
    アクセス制御における Require と Reject の使い方
    
        
    ユーザ名とパスワードによる認証は全体の一部分でしかありません。
        誰がアクセスしてきたかといった情報以外の条件を使いたい、
	とよく思うことでしょう。
        たとえば、どこからアクセスしてきているか、といった具合です。
    
    
        
    承認プロバイダ all,
        env, 
        host,
        ip
        を使うと、リクエストを送信してきているマシンのホスト名や IP アドレス
        といった、ホストベースでのアクセス制御ができます。
    
    
        
    これらプロバイダの扱いは
        Require や
        Reject で
        指定されます。これらのディレクティブは承認プロバイダを登録し、
        リクエスト処理の承認段階で呼び出されます。たとえば:
    
    
        
    
          Require ip address
        
    
    
        
    ここで、address は IP アドレス (あるいは IP アドレスの
        一部) か : 
    
    
        
    
          Require host domain_name
        
    
    
        
    ここで domain_name は FQDN (あるいはドメイン名の一部)
        で、必要であれば複数のアドレスやドメイン名を書くことができます。
    
    
        
    たとえば、スパムメッセージを送信してくる誰かを拒否したい場合、
        次のようになります : 
    
    
        
    
          Reject ip 10.252.46.165
        
    
    
        
    このディレクティブが有効な範囲のコンテンツに対しては、
        そのアドレスからアクセスしてきても見ることができません。
        もしマシン名がわかっていて IP アドレスよりもそちらで
        指定したいのであれば、そのマシン名が使えます。
    
    
        
    
          Reject host host.example.com
        
    
    
        
    また、特定のドメインからのアクセス全てをブロックしたい場合は、
        IP アドレスの一部や、ドメイン名が指定できます :
    
    
        
    
          <SatisfyAll>
    
          
            Reject ip 192.168.205
    
            Reject host phishers.example.com moreidiots.example
               Reject host ke
    
              
          </SatisfyAll>
        
    
    
        
    Reject ディレクティブを
        <SatisfyAll> ブロックの中で使うと、
        許可したいグループにのみアクセスができるように確認できます。
    
    
        
    上記の例では <SatisfyAll>
        を使って、アクセスに合格する前段階で、全ての 
        Reject ディレクティブが
        満たされていることを確認しています。
    
    
    

    
    アクセス制御の後方互換性
    
        
    認証プロバイダベースの機構があるため、以前使用されていたディレクティブ
        Order,
        Allow,
        Deny,
        Satisfy
        は必要なくなりました。
        とはいうものの、古い設定ファイルでの後方互換性を提供するため、
        これらのディレクティブは mod_access_compat モジュールに移されました。
    

        
    これらのディレクティブの抱えていた問題のひとつに、承認の設定行とアクセス制御の設定行の
        関係がとてもあいまいだったことが挙げられます。
        Satisfy ディレクティブは
        リクエスト処理中でそれ自身を呼び出すことによって、これらの 2 つの処理段階を結びつけようとします。
        現在は、これらのディレクティブは mod_access_compat に移動し、
        新しい認証ディレクティブと古いアクセス制御ディレクティブを混ぜて使うことは
        難しくなっています。この問題のため、mod_authz_default モジュールを
        ロードすることがとても重要で、必須になっています。
        mod_authz_default　モジュールの主な目的は、どの承認プロバイダで
        処理されなかった承認リクエストを受けることにあります。
        しかし、古いアクセス制御ディレクティブが用いられた場合には、
        アクセス制御と承認を結びつけて、すべての処理段階の出力結果を見てアクセスに合格するかを決めています。
        ですから、古いディレクティブがうまく動作しない場合は、
        mod_authz_default がロードされていないからかもしれない、
        と疑ってみてください。

    Autenticación es cualquier proceso por el cuál se verifica que uno es 
    quien dice ser. Autorización es cualquier proceso en el cuál cualquiera
    está permitido a estar donde se quiera, o tener información la cuál se
    quiera tener.

    Módulos y Directivas Relacionados
    


    Hay tres tipos de módulos involucrados en los procesos de la autenticación 
	y autorización. Normalmente deberás escoger al menos un módulo de cada grupo.
    



  
    A parte de éstos módulos, también están
  mod_authn_core y
  mod_authz_core. Éstos módulos implementan las directivas 
  esenciales que son el centro de todos los módulos de autenticación.
    

  
    El módulo mod_authnz_ldap es tanto un proveedor de 
  autenticación como de autorización. El módulo
  mod_authz_host proporciona autorización y control de acceso
  basado en el nombre del Host, la dirección IP o características de la propia
  petición, pero no es parte del sistema proveedor de 
  autenticación. Para tener compatibilidad inversa con el mod_access, 
  hay un nuevo modulo llamado mod_access_compat.
    

  
    También puedes mirar el how-to de Control de Acceso , donde se plantean varias formas del control de acceso al servidor.

    Introducción
    
    
    Si se tiene información en nuestra página web que sea información 
    	sensible o pensada para un grupo reducido de usuarios/personas,
    	las técnicas que se describen en este manual, le servirán  
    	de ayuda para asegurarse de que las personas que ven esas páginas sean 
    	las personas que uno quiere.
    

    
    Este artículo cubre la parte "estándar" de cómo proteger partes de un 
    	sitio web que muchos usarán.
    

    
    Nota:
    
    
    Si de verdad es necesario que tus datos estén en un sitio seguro, 
    	considera usar mod_ssl  como método de autenticación adicional a cualquier forma de autenticación.
    
    
    

    top
    

    

    Los Prerequisitos
    
    
    Las directivas que se usan en este artículo necesitaran ponerse ya sea 
    	en el fichero de configuración principal del servidor ( típicamente en 
    	la sección 
    <Directory> de httpd.conf ), o
    en cada uno de los ficheros de configuraciones del propio directorio
    (los archivos .htaccess).
    

    
    Si planea usar los ficheros .htaccess , necesitarás
    tener en la configuración global del servidor, una configuración que permita
    poner directivas de autenticación en estos ficheros. Esto se hace con la
    directiva AllowOverride, la cual especifica
    que directivas, en su caso, pueden ser puestas en cada fichero de configuración
    por directorio.
    

    
    Ya que estamos hablando aquí de autenticación, necesitarás una directiva 
    	AllowOverride como la siguiente:
    	
    

    
    AllowOverride AuthConfig
    


    
    O, si solo se van a poner las directivas directamente en la configuración
    	principal del servidor, deberás tener, claro está, permisos de escritura
    	en el archivo. 
    

    
    Y necesitarás saber un poco de como está estructurado el árbol de 
    	directorios de tu servidor, para poder saber donde se encuentran algunos 
    	archivos. Esto no debería ser una tarea difícil, aún así intentaremos 
    	dejarlo claro llegado el momento de comentar dicho aspecto.
    

    
    También deberás de asegurarte de que los módulos 
    mod_authn_core y mod_authz_core
    han sido incorporados, o añadidos a la hora de compilar en tu binario httpd o
    cargados mediante el archivo de configuración httpd.conf. Estos 
    dos módulos proporcionan directivas básicas y funcionalidades que son críticas
    para la configuración y uso de autenticación y autorización en el servidor web.

    Conseguir que funcione
    
    
    Aquí está lo básico de cómo proteger con contraseña un directorio en tu
     servidor.
    

    
    Primero, necesitarás crear un fichero de contraseña. Dependiendo de que 
    	proveedor de autenticación se haya elegido, se hará de una forma u otra. Para empezar, 
    	usaremos un fichero de contraseña de tipo texto.
    

    
    Este fichero deberá estar en un sitio que no se pueda tener acceso desde
     la web. Esto también implica que nadie pueda descargarse el fichero de 
     contraseñas. Por ejemplo, si tus documentos están guardados fuera de
     /usr/local/apache/htdocs, querrás poner tu archivo de contraseñas en 
     /usr/local/apache/passwd.
    

    
    Para crear el fichero de contraseñas, usa la utilidad 
    	htpasswd que viene con Apache. Esta herramienta se 
    	encuentra en el directorio /bin en donde sea que se ha 
    	instalado el Apache. Si ha instalado Apache desde un paquete de terceros, 
    	puede ser que se encuentre en su ruta de ejecución.
    

    
    Para crear el fichero, escribiremos:
    

    
    
      htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
    

    
    htpasswd te preguntará por una contraseña, y después 
    te pedirá que la vuelvas a escribir para confirmarla:
    

    
    
      $ htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
      New password: mypassword
    
      Re-type new password: mypassword
    
      Adding password for user rbowen
    
    

    
    Si htpasswd no está en tu variable de entorno "path" del 
    sistema, por supuesto deberás escribir la ruta absoluta del ejecutable para 
    poder hacer que se ejecute. En una instalación por defecto, está en:
    /usr/local/apache2/bin/htpasswd
    

    
    Lo próximo que necesitas, será configurar el servidor para que pida una 
    	contraseña y así decirle al servidor que usuarios están autorizados a acceder.
    	Puedes hacer esto ya sea editando el fichero httpd.conf
    de configuración  o usando in fichero .htaccess. Por ejemplo, 
    si quieres proteger el directorio
    /usr/local/apache/htdocs/secret, puedes usar las siguientes 
    directivas, ya sea en el fichero .htaccess localizado en
    following directives, either placed in the file
    /usr/local/apache/htdocs/secret/.htaccess, o
    en la configuración global del servidor httpd.conf dentro de la
    sección <Directory  
    "/usr/local/apache/htdocs/secret"> , como se muestra a continuación:
    

    
    <Directory "/usr/local/apache/htdocs/secret">
AuthType Basic
AuthName "Restricted Files"
# (Following line optional)
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
Require user rbowen
</Directory>
    


    
    Vamos a explicar cada una de las directivas individualmente.
    	La directiva AuthType selecciona el método
    que se usa para autenticar al usuario. El método más común es 
    Basic, y éste es el método que implementa 
    mod_auth_basic. Es muy importante ser consciente,
    de que la autenticación básica, envía las contraseñas desde el cliente 
    al servidor sin cifrar.
    Este método por tanto, no debe ser utilizado para proteger datos muy sensibles,
    a no ser que, este método de autenticación básica, sea acompañado del módulo
    mod_ssl.
    Apache soporta otro método más de autenticación  que es del tipo 
    AuthType Digest. Este método, es implementado por el módulo mod_auth_digest y con el se pretendía crear una autenticación más
    segura. Este ya no es el caso, ya que la conexión deberá realizarse con  mod_ssl en su lugar.
    
    

    
    La directiva AuthName 
    establece el Realm para ser usado en la autenticación. El 
    Realm tiene dos funciones principales.
    La primera, el cliente presenta a menudo esta información al usuario como 
    parte del cuadro de diálogo de contraseña. La segunda, que es utilizado por 
    el cliente para determinar qué contraseña enviar a para una determinada zona 
    de autenticación.
    

    
    Así que, por ejemple, una vez que el cliente se ha autenticado en el área de
    los "Ficheros Restringidos", entonces re-intentará automáticamente
    la misma contraseña para cualquier área en el mismo servidor que es marcado 
    con el Realm de "Ficheros Restringidos"
    Por lo tanto, puedes prevenir que a un usuario se le pida mas de una vez por su
    contraseña, compartiendo así varias áreas restringidas el mismo Realm
    Por supuesto, por razones de seguridad, el cliente pedirá siempre por una contraseña, 
    siempre y cuando el nombre del servidor cambie.
    
    

    
    La directiva AuthBasicProvider es,
    en este caso, opcional, ya que file es el valor por defecto
    para esta directiva. Deberás usar esta directiva si estas usando otro medio
    diferente para la autenticación, como por ejemplo
    mod_authn_dbm o mod_authn_dbd.
    

    
    La directiva AuthUserFile
    establece el path al fichero de contraseñas que acabamos de crear con el 
    comando htpasswd. Si tiene un número muy grande de usuarios, 
    puede ser realmente lento el buscar el usuario en ese fichero de texto plano 
    para autenticar a los usuarios en cada petición.
    Apache también tiene la habilidad de almacenar información de usuarios en 
    unos ficheros de rápido acceso a modo de base de datos.
    El módulo mod_authn_dbm proporciona la directiva AuthDBMUserFile. Estos ficheros pueden ser creados y
    manipulados con el programa dbmmanage y htdbm. 
    Muchos otros métodos de autenticación así como otras opciones, están disponibles en 
    módulos de terceros 
    Base de datos de Módulos disponibles.
    

    
    Finalmente, la directiva Require
    proporciona la parte del proceso de autorización estableciendo el o los
    usuarios que se les está permitido acceder a una región del servidor.
    En la próxima sección, discutiremos las diferentes vías de utilizar la 
    directiva Require.
    

    top
    

    

    Dejar que más de una persona 
	entre
    
    
    Las directivas mencionadas arriba sólo permiten a una persona 
    (especialmente con un usuario que en ej ejemplo es rbowen) 
    en el directorio. En la mayoría de los casos, se querrá permitir el acceso
    a más de una persona. Aquí es donde la directiva 
    AuthGroupFile entra en juego.
    

    
    Si lo que se desea es permitir a más de una persona el acceso, necesitarás
     crear un archivo de grupo que asocie los nombres de grupos con el de personas
     para permitirles el acceso. El formato de este fichero es bastante sencillo, 
     y puedes crearlo con tu editor de texto favorito. El contenido del fichero 
     se parecerá a:
    

   
    
     GroupName: rbowen dpitts sungo rshersey
   
    

    
    Básicamente eso es la lista de miembros los cuales están en un mismo fichero
     de grupo en una sola linea separados por espacios.
    

    
    Para añadir un usuario a tu fichero de contraseñas existente teclee:
    

    
    
      htpasswd /usr/local/apache/passwd/passwords dpitts
    
    

    
    Te responderá lo mismo que anteriormente, pero se añadirá al fichero 
    	existente en vez de crear uno nuevo. (Es decir el flag -c será 
    	el que haga que se genere un nuevo 
    fichero de contraseñas).
    

    
    Ahora, tendrá que modificar su fichero .htaccess para que sea 
    parecido a lo siguiente:
    

    
    AuthType Basic
AuthName "By Invitation Only"
# Optional line:
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
AuthGroupFile "/usr/local/apache/passwd/groups"
Require group GroupName
    


    
    Ahora, cualquiera que esté listado en el grupo GroupName,
    y tiene una entrada en el fichero de contraseñas, se les 
    permitirá el acceso, si introducen su contraseña correctamente.
    

    
    Hay otra manera de dejar entrar a varios usuarios, que es menos específica.
    En lugar de crear un archivo de grupo, sólo puede utilizar la siguiente 
    directiva:
    

    
    Require valid-user
    


    
    Usando ésto en vez de la línea Require user rbowen
     permitirá a cualquier persona acceder, la cuál aparece en el archivo de 
     contraseñas, y que introduzca correctamente su contraseña. Incluso puede 
     emular el comportamiento del grupo aquí, sólo manteniendo un fichero de 
     contraseñas independiente para cada grupo. La ventaja de este enfoque es 
     que Apache sólo tiene que comprobar un archivo, en lugar de dos. La desventaja 
     es que se tiene que mantener un montón de ficheros de contraseña de grupo, y 
     recuerde hacer referencia al fichero correcto en la directiva
    AuthUserFile.
    

    top
    

    

    Posibles Problemas
    
    
    Debido a la forma en que se especifica la autenticación básica,
    su nombre de usuario y la contraseña deben ser verificados cada vez 
    que se solicita un documento desde el servidor. Esto es, incluso si 
    se  vuelve a cargar la misma página, y para cada imagen de la página (si
    provienen de un directorio protegido). Como se puede imaginar, esto
    ralentiza las cosas un poco. La cantidad que ralentiza las cosas es 
    proporcional al tamaño del archivo de contraseñas, porque tiene que 
    abrir ese archivo, recorrer lista de usuarios hasta que llega a su nombre.
    Y tiene que hacer esto cada vez que se carga una página.
    

    
    Una consecuencia de esto, es que hay un limite práctico de cuantos 
    usuarios puedes introducir en el fichero de contraseñas. Este límite
    variará dependiendo de la máquina en la que tengas el servidor,
    pero puedes notar ralentizaciones en cuanto se metan cientos de entradas,
    y por lo tanto consideraremos entonces otro método de autenticación
    en ese momento.
	
    

    top
    

    

    Método alternativo de almacenamiento de las 
	contraseñas
    

    
    Debido a que el almacenamiento de las contraseñas en texto plano tiene 
    	el problema mencionado anteriormente, puede que se prefiera guardar 
    	las contraseñas en otro lugar como por ejemplo una base de datos.
    	
    

    
    Los módulos mod_authn_dbm y mod_authn_dbd son
    dos módulos que hacen esto posible. En vez de seleccionar la directiva de fichero
    AuthBasicProvider , en su lugar
    se puede elegir dbm o dbd como formato de almacenamiento.
    

    
    Para seleccionar los ficheros de tipo dbm en vez de texto plano, podremos hacer algo parecido a lo siguiente:
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider dbm
    AuthDBMUserFile "/www/passwords/passwd.dbm"
    Require valid-user
</Directory>
    


    
    Hay otras opciones disponibles. Consulta la documentación de
    mod_authn_dbm para más detalles.
    

    top
    

    

    Uso de múltiples proveedores
    

    
    Con la introducción de la nueva autenticación basada en un proveedor y
     una arquitectura de autorización, ya no estaremos restringidos a un único
     método de autenticación o autorización. De hecho, cualquier número de 
     los proveedores pueden ser mezclados y emparejados para ofrecerle 
     exactamente el esquema que se adapte a sus necesidades. 
     En el siguiente ejemplo, veremos como ambos proveedores tanto el fichero 
     como el LDAP son usados en la autenticación:
     
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file ldap
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    Require valid-user
</Directory>
    


    
    En este ejemplo el fichero, que actúa como proveedor, intentará autenticar 
    	primero al usuario. Si no puede autenticar al usuario, el proveedor del LDAP
    	será llamado para que realice la autenticación.
    	Esto permite al ámbito de autenticación ser amplio, si su organización 
    	implementa más de un tipo de almacén de autenticación. 
    	Otros escenarios de autenticación y autorización pueden incluir la 
    	mezcla de un tipo de autenticación con un tipo diferente de autorización.
    	Por ejemplo, autenticar contra un fichero de contraseñas pero autorizando
    	dicho acceso mediante el directorio del LDAP.
    

    
    Así como múltiples métodos y proveedores de autenticación pueden 
    	ser implementados, también pueden usarse múltiples formas de 
    	autorización.
    	En este ejemplo ambos ficheros de autorización de grupo así como 
    	autorización de grupo mediante LDAP va a ser usado:
    
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    AuthGroupFile "/usr/local/apache/passwd/groups"
    Require group GroupName
    Require ldap-group cn=mygroup,o=yourorg
</Directory>
    


    
    Para llevar la autorización un poco más lejos, las directivas 
    	de autorización de contenedores tales como
    <RequireAll>
    and
    <RequireAny>
    nos permiten aplicar una lógica de en qué orden se manejará la autorización dependiendo
    de la configuración y controlada a través de ella.
    Mire también Contenedores de
    Autorización para ejemplos de cómo pueden ser aplicados.
    


    top
    

    

    Más allá de la Autorización
    

    
    El modo en que la autorización puede ser aplicada es ahora mucho más flexible
    	que us solo chequeo contra un almacén de datos (contraseñas). Ordenando la 
    	lógica y escoger la forma en que la autorización es realizada, ahora es posible 
    
    

    
    Aplicando la lógica y ordenación
    
        
    Controlar el cómo y en qué orden se va a aplicar la autorización ha 
        	sido un misterio en el pasado. En Apache 2.2 un proveedor del 
        	mecanismo de autenticación fue introducido para disociar el proceso actual
        	de autenticación y soportar funcionalidad.
        	Uno de los beneficios secundarios fue que los proveedores de autenticación
        	podían ser configurados y llamados en un orden especifico que no dependieran
        	en el orden de carga del propio modulo. 
        	Este proveedor de dicho mecanismo, ha sido introducido en la autorización
        	también. Lo que esto significa es que la directiva 
        	Require 
        	no sólo especifica que método de autorización deberá ser usado, si no
        	también especifica el orden en que van a ser llamados. Múltiples
        	métodos de autorización son llamados en el mismo orden en que la directiva
            Require aparece en la
            configuración.
        
    

        
    
        	Con la Introducción del contenedor de directivas de autorización tales como
	        <RequireAll>
	        y
	        <RequireAny>,
	        La configuración también tiene control sobre cuándo se llaman a los métodos
	        de autorización y qué criterios determinan cuándo se concede el acceso.
	        Vease
	        Contenedores de autorización
	        Para un ejemplo de cómo pueden ser utilizados para expresar una lógica 
	        más compleja de autorización.
	    
    

        
    
        	Por defecto todas las directivas 
        	Require
       		son manejadas como si estuvieran contenidas en una directiva
       		<RequireAny>.
       		En otras palabras, Si alguno de los métodos de autorización 
       		especificados tiene éxito, se concede la autorización.
       	
    

    

    
    Uso de los proveedores de autorización para 
    	el control de acceso
    

    	
    
    		La autenticación de nombre de usuario y contraseña es sólo parte
    		de toda la historia que conlleva el proceso. Frecuentemente quiere
    		dar acceso a la gente en base a algo más que lo que son.
    		Algo como de donde vienen.
    	
    

        
    
        	Los proveedores de autorización all,
        	env, host y ip
        	te permiten denegar o permitir el acceso basándose en otros
        	criterios como el nombre de la máquina o la IP de la máquina que
        	realiza la consulta para un documento.
        
    

        
    
        	El uso de estos proveedores se especifica a través de la directiva
        	Require.
        	La directiva registra los proveedores de autorización que serán llamados
        	durante la solicitud de la fase del proceso de autorización. Por ejemplo:
        
    

        
    Require ip address
        
    


        
    
        	Donde address es una dirección IP (o una dirección IP parcial) 
        	o bien:
        
    

        
    Require host domain_name
        
    


        
    
        	Donde domain_name es el nombre completamente cualificado de un nombre 
	        de dominio (FQDN) (o un nombre parcial del dominio);
	        puede proporcionar múltiples direcciones o nombres de dominio, si se desea.
        
    

        
    
        	Por ejemplo, si alguien envía spam a su tablón de mensajes y desea
        	mantenerlos alejados, podría hacer lo siguiente:
    

        
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>

        	Uno de los efectos secundarios de adoptar proveedores basados en 
        	mecanismos de autenticación es que las directivas anteriores
	        Order,
	        Allow,
	        Deny y
        	Satisfy ya no son necesarias.
        	Sin embargo, para proporcionar compatibilidad con configuraciones antiguas,
        	estas directivas se han movido al módulo mod_access_compat.
        
    

        
    Nota:
    
	        
    
	        	Las directivas proporcionadas por mod_access_compat 
	        	han quedado obsoletas por mod_authz_host. Mezclar 
	        	directivas antiguas como

	            Allow ó 
	            Deny con las nuevas 
	            como 
	            Require 
	            es técnicamente posible pero desaconsejable. El módulo 
	            mod_access_compat se creó para soportar configuraciones
	            que contuvieran sólo directivas antiguas para facilitar la actualización
	            a la versión 2.4.

    Cache de Autenticación
    
	
    
		Puede haber momentos en que la autenticación ponga una carga 
		inaceptable en el proveedor (de autenticación) o en tu red.
		Esto suele afectar a los usuarios de mod_authn_dbd 
		(u otros proveedores de terceros/personalizados).
		Para lidiar con este problema, HTTPD 2.3/2.4 introduce un nuevo proveedor
		de caché  mod_authn_socache para cachear las credenciales 
		y reducir la carga en el proveedor(es) original.
	
    
    
    
    	Esto puede ofrecer un aumento de rendimiento sustancial para algunos usuarios.

    Authentication and Authorization
    
      
    
        
    Authentication is any process by which you verify that
        someone is who they claim they are. Authorization is any
        process by which someone is allowed to be where they want to
        go, or to have information that they want to have.
    

        
    See: Authentication, Authorization
    
      
    
    
    

    
    
      
    Access Control
    
      
    
        
    Access control refers to the process of restricting, or
        granting access to a resource based on arbitrary criteria. There
        are a variety of different ways that this can be
        accomplished.

    Dynamic Content with CGI
    
      
    
        
    The CGI (Common Gateway Interface) defines a way for a web
        server to interact with external content-generating programs,
        which are often referred to as CGI programs or CGI scripts. It
        is a simple way to put dynamic content on
        your web site. This document will be an introduction to setting
        up CGI on your Apache web server, and getting started writing
        CGI programs.

    .htaccess files
    
      
    
        
    .htaccess files provide a way to make configuration
        changes on a per-directory basis. A file, containing one or more
        configuration directives, is placed in a particular document directory,
        and the directives apply to that directory, and all subdirectories thereof.

    HTTP/2 with httpd
    
      
    
      
    HTTP/2 is the evolution of the world's most successful application layer protocol, HTTP. 
        It focuses on making more efficient use of network resources without changing the semantics of HTTP.
        This guide explains how HTTP/2 is implemented in httpd, showing basic configurations tips and 
        best practices.

    Introduction to Server Side Includes
    
      
    
        
    SSI (Server Side Includes) are directives that are placed in
        HTML pages, and evaluated on the server while the pages are
        being served. They let you add dynamically generated content to
        an existing HTML page, without having to serve the entire page
        via a CGI program, or other dynamic technology.

    Per-user web directories
    
      
    
        
    On systems with multiple users, each user can be permitted to have a
        web site in their home directory using the UserDir directive. Visitors
        to a URL http://example.com/~username/ will get content
        out of the home directory of the user "username", out of
        the subdirectory specified by the UserDir directive.

    Reverse Proxy guide
    
      
    
        
    Apache httpd has extensive capabilities as a reverse proxy server using the
        ProxyPass directive as well as
        BalancerMember to create sophisticated
        reverse proxying implementations which provide for high-availability, load
        balancing and failover, cloud-based clustering and dynamic on-the-fly reconfiguration.

    Rewriting URLs with mod_rewrite
    
      
    
        
    Rewriting URLs with (and without)
        mod_rewrite tends to be one of the most
        frequently asked topics on our mailing lists and IRC channels.
        We have devoted and entire section of our
        documentation to howtos and recipes around this topic.

    Related ModulesRelated Directives
    

    
    You should avoid using .htaccess files completely if you have access to
    httpd main server config file. Using .htaccess files slows down your Apache http server.
    Any directive that you can include in a .htaccess file is better set in a Directory block, as it will have the same effect with better performance.
    

    top
    

    

    What they are/How to use them
    


    
    .htaccess files (or "distributed configuration files")
    provide a way to make configuration changes on a per-directory basis. A
    file, containing one or more configuration directives, is placed in a
    particular document directory, and the directives apply to that
    directory, and all subdirectories thereof.
    

    
    Note:
    
      
    If you want to call your .htaccess file something
      else, you can change the name of the file using the AccessFileName directive. For example,
      if you would rather call the file .config then you
      can put the following in your server configuration file:
    

      
    AccessFileName ".config"
    

    
    

    
    In general, .htaccess files use the same syntax as
    the main configuration
    files. What you can put in these files is determined by the
    AllowOverride directive. This
    directive specifies, in categories, what directives will be
    honored if they are found in a .htaccess file. If a
    directive is permitted in a .htaccess file, the
    documentation for that directive will contain an Override section,
    specifying what value must be in AllowOverride in order for that
    directive to be permitted.
    

    
    For example, if you look at the documentation for the AddDefaultCharset
    directive, you will find that it is permitted in .htaccess
    files. (See the Context line in the directive summary.) The Override line reads
    FileInfo. Thus, you must have at least
    AllowOverride FileInfo in order for this directive to be
    honored in .htaccess files.
    

    
    Example:
    
        
    
          Context:
          server config, virtual host, directory, .htaccess
        
    

        
    
          Override:
          FileInfo
        
    
      
    

    
    If you are unsure whether a particular directive is permitted in a
    .htaccess file, look at the documentation for that
    directive, and check the Context line for ".htaccess".
    
    
    top
    

    

    When (not) to use .htaccess files
    

    
    In general, you should only use .htaccess files when
    you don't have access to the main server configuration file. There is,
    for example, a common misconception that user authentication should
    always be done in .htaccess files, and, in more recent years,
    another misconception that mod_rewrite directives
    must go in .htaccess files. This is simply not the
    case. You can put user authentication configurations in the main server
    configuration, and this is, in fact, the preferred way to do
    things. Likewise, mod_rewrite directives work better,
    in many respects, in the main server configuration.
    

    
    .htaccess files should be used in a case where the
    content providers need to make configuration changes to the server on a
    per-directory basis, but do not have root access on the server system.
    In the event that the server administrator is not willing to make
    frequent configuration changes, it might be desirable to permit
    individual users to make these changes in .htaccess files
    for themselves. This is particularly true, for example, in cases where
    ISPs are hosting multiple user sites on a single machine, and want
    their users to be able to alter their configuration.
    

    
    However, in general, use of .htaccess files should be
    avoided when possible. Any configuration that you would consider
    putting in a .htaccess file, can just as effectively be
    made in a <Directory> section in your main server
    configuration file.
    

    
    There are two main reasons to avoid the use of
    .htaccess files.
    

    
    The first of these is performance. When AllowOverride
    is set to allow the use of .htaccess files, httpd will
    look in every directory for .htaccess files. Thus,
    permitting .htaccess files causes a performance hit,
    whether or not you actually even use them! Also, the
    .htaccess file is loaded every time a document is
    requested.
    

    
    Further note that httpd must look for .htaccess files
    in all higher-level directories, in order to have a full complement of
    directives that it must apply. (See section on how
    directives are applied.) Thus, if a file is requested out of a
    directory /www/htdocs/example, httpd must look for the
    following files:
    

    
    
      /.htaccess
    
      /www/.htaccess
    
      /www/htdocs/.htaccess
    
      /www/htdocs/example/.htaccess
    
    

    
    And so, for each file access out of that directory, there are 4
    additional file-system accesses, even if none of those files are
    present. (Note that this would only be the case if
    .htaccess files were enabled for /, which
    is not usually the case.)
    

    
    In the case of RewriteRule directives, in
    .htaccess context these regular expressions must be
    re-compiled with every request to the directory, whereas in main
    server configuration context they are compiled once and cached.
    Additionally, the rules themselves are more complicated, as one must
    work around the restrictions that come with per-directory context
    and mod_rewrite. Consult the Rewrite Guide for more
    detail on this subject.
    

    
    The second consideration is one of security. You are permitting
    users to modify server configuration, which may result in changes over
    which you have no control. Carefully consider whether you want to give
    your users this privilege. Note also that giving users less
    privileges than they need will lead to additional technical support
    requests. Make sure you clearly tell your users what level of
    privileges you have given them. Specifying exactly what you have set
    AllowOverride to, and pointing them
    to the relevant documentation, will save yourself a lot of confusion
    later.
    

    
    Note that it is completely equivalent to put a .htaccess
    file in a directory /www/htdocs/example containing a
    directive, and to put that same directive in a Directory section
    <Directory "/www/htdocs/example"> in your main server
    configuration:
    

    
    .htaccess file in /www/htdocs/example:
    

    
    Contents of .htaccess file in
    /www/htdocs/example
    AddType text/example ".exm"
    

    

    
    Section from your httpd.conf
    file
    <Directory "/www/htdocs/example">
    AddType text/example ".exm"
</Directory>
    

    

    
    However, putting this configuration in your server configuration
    file will result in less of a performance hit, as the configuration is
    loaded once when httpd starts, rather than every time a file is
    requested.
    

    
    The use of .htaccess files can be disabled completely
    by setting the AllowOverride
    directive to none:
    

    
    AllowOverride None
    


    top
    

    

    How directives are applied
    

    
    The configuration directives found in a .htaccess file
    are applied to the directory in which the .htaccess file
    is found, and to all subdirectories thereof. However, it is important
    to also remember that there may have been .htaccess files
    in directories higher up. Directives are applied in the order that they
    are found. Therefore, a .htaccess file in a particular
    directory may override directives found in .htaccess files
    found higher up in the directory tree. And those, in turn, may have
    overridden directives found yet higher up, or in the main server
    configuration file itself.
    

    
    Example:
    

    
    In the directory /www/htdocs/example1 we have a
    .htaccess file containing the following:
    

    
    Options +ExecCGI
    


    
    (Note: you must have "AllowOverride Options" in effect
    to permit the use of the "Options" directive in
    .htaccess files.)
    

    
    In the directory /www/htdocs/example1/example2 we have
    a .htaccess file containing:
    

    
    Options Includes
    


    
    Because of this second .htaccess file, in the directory
    /www/htdocs/example1/example2, CGI execution is not
    permitted, as only Options Includes is in effect, which
    completely overrides any earlier setting that may have been in
    place.
    

    
    Merging of .htaccess with the main
    configuration files
    

    
    As discussed in the documentation on Configuration Sections,
    .htaccess files can override the <Directory> sections for
    the corresponding directory, but will be overridden by other types
    of configuration sections from the main configuration files. This
    fact can be used to enforce certain configurations, even in the
    presence of a liberal AllowOverride setting. For example, to
    prevent script execution while allowing anything else to be set in
    .htaccess you can use:
    

    
    <Directory "/www/htdocs">
    AllowOverride All
</Directory>

<Location "/">
    Options +IncludesNoExec -ExecCGI
</Location>
    


    
    This example assumes that your DocumentRoot is /www/htdocs.

    Authentication example
    

    
    If you jumped directly to this part of the document to find out how
    to do authentication, it is important to note one thing. There is a
    common misconception that you are required to use
    .htaccess files in order to implement password
    authentication. This is not the case. Putting authentication directives
    in a <Directory>
    section, in your main server configuration file, is the preferred way
    to implement this, and .htaccess files should be used only
    if you don't have access to the main server configuration file. See above for a discussion of when you should and should
    not use .htaccess files.
    

    
    Having said that, if you still think you need to use a
    .htaccess file, you may find that a configuration such as
    what follows may work for you.
    

    
    .htaccess file contents:
    

    
    AuthType Basic
AuthName "Password Required"
AuthUserFile "/www/passwords/password.file"
AuthGroupFile "/www/passwords/group.file"
Require group admins
    


    
    Note that AllowOverride AuthConfig must be in effect
    for these directives to have any effect.
    

    
    Please see the authentication tutorial for a
    more complete discussion of authentication and authorization.
    

    top
    

    

    Server Side Includes example
    

    
    Another common use of .htaccess files is to enable
    Server Side Includes for a particular directory. This may be done with
    the following configuration directives, placed in a
    .htaccess file in the desired directory:
    

    
    Options +Includes
AddType text/html shtml
AddHandler server-parsed shtml
    


    
    Note that AllowOverride Options and AllowOverride
    FileInfo must both be in effect for these directives to have any
    effect.
    

    
    Please see the SSI tutorial for a more
    complete discussion of server-side includes.
    

    top
    

    

    Rewrite Rules in .htaccess files
    

    When using RewriteRule in
.htaccess files, be aware that the per-directory context
changes things a bit. In particular, rules are taken to be relative to
the current directory, rather than being the original requested URI.
Consider the following examples:
    


    # In httpd.conf
RewriteRule "^/images/(.+)\.jpg" "/images/$1.png"

# In .htaccess in root dir
RewriteRule "^images/(.+)\.jpg" "images/$1.png"

# In .htaccess in images/
RewriteRule "^(.+)\.jpg" "$1.png"
    



    In a .htaccess in your document directory, the leading
slash is removed from the value supplied to RewriteRule, and in the
images subdirectory, /images/ is removed from
it. Thus, your regular expression needs to omit that portion as
well.
    


    Consult the mod_rewrite documentation for

    CGI example
    

    
    Finally, you may wish to use a .htaccess file to permit
    the execution of CGI programs in a particular directory. This may be
    implemented with the following configuration:
    

    
    Options +ExecCGI
AddHandler cgi-script cgi pl
    


    
    Alternately, if you wish to have all files in the given directory be
    considered to be CGI programs, this may be done with the following
    configuration:
    

    
    Options +ExecCGI
SetHandler cgi-script
    


    
    Note that AllowOverride Options and AllowOverride
    FileInfo must both be in effect for these directives to have any
    effect.
    

    
    Please see the CGI tutorial for a more
    complete discussion of CGI programming and configuration.

    Troubleshooting
    

    
    When you put configuration directives in a .htaccess
    file, and you don't get the desired effect, there are a number of
    things that may be going wrong.
    

    
    Most commonly, the problem is that AllowOverride is not
    set such that your configuration directives are being honored. Make
    sure that you don't have a AllowOverride None in effect
    for the file scope in question. A good test for this is to put garbage
    in your .htaccess file and reload the page. If a server error is
    not generated, then you almost certainly have AllowOverride
    None in effect.
    

    
    If, on the other hand, you are getting server errors when trying to
    access documents, check your httpd error log. It will likely tell you
    that the directive used in your .htaccess file is not
    permitted.
    

    
    
    [Fri Sep 17 18:43:16 2010] [alert] [client 192.168.200.51] /var/www/html/.htaccess: DirectoryIndex not allowed here
    
    

    
    This will indicate either that you've used a directive that is
    never permitted in .htaccess files, or that you simply
    don't have AllowOverride set to
    a level sufficient for the directive you've used. Consult the
    documentation for that particular directive to determine which is
    the case.
    

    
    Alternately, it may tell you that you had a syntax error in your
    usage of the directive itself.
    

    
    
    [Sat Aug 09 16:22:34 2008] [alert] [client 192.168.200.51] /var/www/html/.htaccess: RewriteCond: bad flag delimiters
    
    

    
    In this case, the error message should be specific to the
    particular syntax error that you have committed.

    Módulos RelacionadosDirectivas Relacionadas
    

    
    Debería evitar usar ficheros .htaccess completamente si
    tiene acceso al fichero de configuración principal de httpd. Usar ficheros 
    .htaccess ralentiza su servidor Apache http. Cualquier 
    directiva que pueda incluir en un fichero .htaccess 
    estará mejor configurada dentro de una sección 
    Directory, tendrá el mismo efecto y
    mejor rendimiento.
    

    top
    

    

    Qué son/Cómo usarlos
    


    
    Los ficheros .htaccess (o "ficheros de configuración
    distribuida") facilitan una forma de realizar cambios en la configuración
    en contexto directorio. Un fichero, que contiene una o más directivas, se 
    coloca en un documento específico de un directorio, y estas directivas 
    aplican a ese directorio y todos sus subdirectorios.
    

    
    Nota:
    
      
    Si quiere llamar a su fichero .htaccess de otra manera, 
      puede cambiar el nombre del fichero usando la directiva AccessFileName. Por ejemplo, si usted prefiere
      llamar al fichero .config, entonces puede poner lo siguiente
      en el fichero de configuración de su servidor:
    

      
    AccessFileName ".config"
    

    
    

    
    Generalmente, los ficheros .htaccess usan la misma sintáxis 
    que los ficheros de la configuración
    principal. Lo que puede utilizar en estos ficheros lo determina la 
    directiva AllowOverride. Esta directiva
    especifica, en categorías, qué directivas tendrán efecto si se encuentran en 
    un fichero .htaccess. Si se permite una directiva en un fichero 
    .htaccess, la documentación para esa directiva contendrá una 
    sección Override, especificando qué valor debe ir en 
    AllowOverride para que se permita esa
    directiva.
    

    
    Por ejemplo, si busca en la documentación la directiva AddDefaultCharset, encontrará que se permite en
    ficheros .htaccess. (Vea la línea de Contexto en el sumario de
    la directiva.) La línea Override muestra
    FileInfo. De este modo, debe tener al menos
    AllowOverride FileInfo para que esta directiva se aplique en
    ficheros .htaccess.
    

    
    Ejemplo:
    
        
    
          Context:
          server config, virtual host, directory, .htaccess
        
    

        
    
          Override:
          FileInfo
        
    
      
    

    
    Si no está seguro de cuándo, una directiva en concreto, se puede usar en un 
    fichero .htaccess, consulte la documentación para esa directiva, 
    y compruebe la línea Context buscando ".htaccess".
    
    
    top
    

    

    Cuando (no) usar ficheros .htaccess
    

    
    Generalmente, solo debería usar ficheros .htaccess cuando no
    tiene acceso al fichero principal de configuración del servidor. Hay, por
    ejemplo, una creencia errónea de que la autenticación de usuario debería 
    hacerse siempre dentro de ficheros .htaccess, y, más recientemente, otra creencia errónea de que las directivas de 
    mod_rewrite deben ir en ficheros .htaccess. 
    Esto sencillamente no es el caso. Puede poner las configuraciones de 
    autenticación de usuario en la configuración principal del servidor, y esto 
    es de hecho, el método preferido de configurar Apache. Del mismo modo, las 
    directivas mod_rewrite funcionan mejor, en muchos sentidos, en 
    el fichero de configuración principal del servidor.
    

    
    Los ficheros .htaccess deberían usarse cuando su proveedor 
    de contenidos le permite hacer modificaciones de configuración 
    en contexto directorio, pero usted no tiene acceso de root en el servidor.
    En el caso de que el administrador no esté dispuesto a hacer cambios 
    frecuentes en la configuración, puede que sea necesario permitir a usuarios
    individuales realizar estos cambios de configuración en ficheros 
    .htaccess por ellos mismos. Lo cual ocurre a menudo, por 
    ejemplo, en casos donde los ISP están albergando múltiples sitios web de 
    usuario en una sola máquina, y quieren que sus usuarios tengan la 
    posibilidad de modificar sus configuraciones.
    

    
    Aun así, generalmente, el uso de ficheros .htaccess debería
    evitarse cuando sea posible. Cualquier configuración que consideraría poner
    en un fichero .htaccess, puede usarse con la misma efectividad
    en una sección <Directory> en el fichero de configuración 
    del servidor.
    

    
    Hay dos razones para evitar el uso de ficheros .htaccess.
    

    
    La primera es el rendimiento. Cuando AllowOverride
    está configurado para permitir el uso de ficheros .htaccess, 
    httpd buscará ficheros .htaccess en cada directorio. Así,
    permitiendo ficheros .htaccess provoca una pérdida de 
    rendimiento, ¡incluso aunque no los use! Además, los ficheros 
    .htaccess se cargan cada vez que se solicita un documento.
    

    
    Además tenga en cuenta que httpd debe buscar ficheros 
    .htaccess en todos los directorios de mayor jerarquía, 
    para poder terner la lista completa de directivas que debe aplicar. (Vea
    la sección sobre Cómo se aplican las directivas.) Así, si
    se solicita un fichero de un directorio /www/htdocs/example, 
    httpd debe buscar los siguientes ficheros:
    

    
    
      /.htaccess
    
      /www/.htaccess
    
      /www/htdocs/.htaccess
    
      /www/htdocs/example/.htaccess
    
    

    
    De esta manera, por cada acceso a un fichero de ese directorio, hay 4 
    accesos adicionales al sistema de ficheros, incluso si ninguno de esos 
    ficheros está presente. (Tenga en cuenta que este caso solo se daría si los 
    ficheros .htaccess están activados en /, que 
    generalmente no es el caso.).
    

    
    En el caso de las directivas RewriteRule, en el contexto de
    .htaccess estas expresiones regulares deben recompilarse con 
    cada solicitud a ese directorio, cuando en el contexto de configuración del
    servidor solo se compilan una vez y se cachean. Adicionalmente, las reglas
    en sí mismas son más complicadas, puesto que uno debe sortear las 
    restricciones que vienen acompañadas del contexto directorio y 
    mod_rewrite. Consulte la  Guía de Rewrite para un mayor 
    detalle sobre este tema.
    

    
    La segunda consideración es de seguridad. Estará permitiendo que usuarios
    modifiquen la configuración del servidor, lo cual puede dar lugar a cambios sobre los que usted no tendrá ningún control. Medite profundamente si debe 
    dar a sus usuarios ese privilegio. Además tenga en cuenta que dar a los usuarios menos privilegios de los que necesitan dará lugar a más peticiones 
    de soporte. Asegúrese de que le indica a sus usuarios claramente el nivel de privilegios que les está dando. Especificando exactamente cómo ha 
    configurado AllowOverride, e invíteles 
    a revisar la documentación relacionada, lo cual le ahorrará 
    bastantes confusiones más adelante.
    

    
    Tenga en cuenta que esto es equivalente por completo a poner un fichero
    .htaccess en un directorio /www/htdocs/example 
    con una directiva, y poner la misma directiva en una sección 
    Directory <Directory "/www/htdocs/example"> en su 
    configuración principal del servidor:
    

    
    Fichero .htaccess en /www/htdocs/example:
    

    
    Contenido de fichero .htaccess en
    /www/htdocs/example
    AddType text/example ".exm"
    

    

    
    Sección de su fichero httpd.conf
    <Directory "/www/htdocs/example">
    AddType text/example ".exm"
</Directory>
    

    

    
    Aun así, poniendo ésta en el fichero de configuración dará como resultado
    una menor pérdida de rendimiento, y como la configuración se carga una vez
    cuando el httpd arranca, en lugar de cada vez que se solicita un fichero.
    

    
    El uso de ficheros .htaccess puede desactivarse por completo
    configurando la directiva AllowOverride
    a none:
    

    
    AllowOverride None
    


    top
    

    

    How directives are applied
    

    
    Las directivas de configuración que se encuentran en el fichero
    .htaccess se aplican al directorio en el que el fichero
    .htaccess se encuentra, y a todos sus subdirectorios. Sin 
    embargo, es importante recordar que puede haber otros ficheros 
    .htaccess en directorios previos. Las directivas se aplican en
    el orden en el que se encuentran. Por lo tanto, un fichero 
    .htaccess puede sobrescribir directivas que se encuentran
    en ficheros .htaccess que se encuentran en directorios previos 
    del árbol de directorios. Y estos, en cambio, pueden haber sobrescrito 
    directivas que se encontraban más arriba, o en el fichero principal de 
    configuración del servidor mismo.
    

    
    Ejemplo:
    

    
    En el directorio /www/htdocs/example1 tenemos un fichero
    .htaccess que contiene lo siguiente:
    

    
    Options +ExecCGI
    


    
    (Nota: debe terner "AllowOverride Options" configurado para
    permitir el uso de la directiva "Options" en ficheros 
    .htaccess files.)
    

    
    En el directorio /www/htdocs/example1/example2 tenemos un
    fichero .htaccess que contiene:
    

    
    Options Includes
    


    
    Por este segundo fichero .htaccess, en el directorio
    /www/htdocs/example1/example2, la ejecución de CGI execution no
    está permitida, porque solo se ha definido Options Includes, 
    que sobrescribe completamente una configuración previa que se pudiera haber
    definido.
    

    
    Incorporando el .htaccess en los ficheros de 
    configuración principal
    

    
    Como se ha comentado en la documentación en las Secciones de Configuración, los ficheros
    .htaccess pueden sobrescribir las secciones <Directory> por el directorio
    correspondiente, pero se sobrescribirán por otros tipos de secciones de 
    configuración de los ficheros de configuración principal. Este hecho se
    puede usar para forzar ciertas configuraciones, incluso en presencia
    de una configuración laxa de 
    AllowOverride. Por ejemplo, para 
    prevenir la ejecución de un script mientras se permite cualquier otra cosa 
    en .htaccess puede usar:
    

    
    <Directory "/www/htdocs">
    AllowOverride All
</Directory>

<Location "/">
    Options +IncludesNoExec -ExecCGI
</Location>
    


    
    Este ejemplo asume que su DocumentRoot es /www/htdocs.

    Ejemplo de Autenticación
    

    
    Si saltó directamente a esta parte del documento para averiguar como 
    hacer la autenticación, es important que tenga en cuenta una cosa. Hay una 
    creencia errónea de que necesita usar ficheros .htaccess para
    configurar autenticación con contraseña. Este no es el caso. Colocar las
    directivas de autenticación en una sección 
    <Directory>, en su fichero
    de configuración principal, es el método recomendado para configurar esto, 
    y los ficheros .htaccess deberían usarse solamente si no tiene 
    acceso al fichero de configuración principal del servidor. Vea más arriba una explicación de cuando debería y cuando no
    debería usar ficheros .htaccess.
    

    
    Dicho esto, si todavía cree que debe usar el fichero
    .htaccess, podrá ver que una configuración como la que sigue 
    podría servirle.
    

    
    Contenido del fichero .htaccess:
    

    
    AuthType Basic
AuthName "Password Required"
AuthUserFile "/www/passwords/password.file"
AuthGroupFile "/www/passwords/group.file"
Require group admins
    


    
    Tenga en cuenta que AllowOverride AuthConfig debe estar
    habilitado para que estas directivas tengan algún efecto.
    

    
    Por favor vea el tutorial de autenticación para
    una explicación más completa de la autenticación y la autorización.
    

    top
    

    

    Ejemplo de Server Side Includes
    

    
    Otro uso común de ficheros .htaccess es activar Server Side 
    Includes para un directorio en particular. Esto puede hacerse 
    con las siguientes directivas de configuración, colocadas en un fichero
    .htaccess y el directorio deseado:
    

    
    Options +Includes
AddType text/html "shtml"
AddHandler server-parsed shtml
    


    
    Tenga en cuenta que AllowOverride Options y 
    AllowOverride FileInfo deben estar activadas para que estas 
    directivas tengan efecto.
    

    
    Por favor vea el tutorial de SSI para una
    explicación más completa de server-side includes.
    

    top
    

    

    Reglas de Rewrite en ficheros .htaccess
    
    
    Cuando use RewriteRule en
    ficheros .htaccess, tenga en cuenta que el contexto 
    directorio cambia las cosas un poco. En concreto, las reglas son 
    relativas al directorio actual, en lugar de serlo de la petición de URI 
    solicitada originalmente.
    Considere los siguientes ejemplos:
    


    # En httpd.conf
RewriteRule "^/images/(.+)\.jpg" "/images/$1.png"

# En .htaccess en el directorio raíz
RewriteRule "^images/(.+)\.jpg" "images/$1.png"

# En .htaccess en images/
RewriteRule "^(.+)\.jpg" "$1.png"
    


    
    En un .htaccess en cualquier directorio del DocumentRoot, la 
    barra ("/") inicial se elimina del valor facilitado a RewriteRule, y en el subdirectorio 
    images, se elimina /images/ también de este valor. 
    Así, su expresión regular necesita omitir también esa parte.
    

    
    Consulte la documentación de mod_rewrite para 
    más detalles al usar mod_rewrite.
    


    top
    

    

    Ejemplo de CGI
    

    
    Finalmente, puede que quiera usar un fichero .htaccess para
    permitir la ejecución de programas CGI en un directorio en particular. Esto
    se puede implementar con la siguiente configuración:
    

    
    Options +ExecCGI
AddHandler cgi-script "cgi" "pl"
    


    
    Alternativamente, si quiere considerar como programas CGI todos los 
    ficheros de un directorio concreto, esto se puede conseguir con la siguiente 
    configuración:
    

    
    Options +ExecCGI
SetHandler cgi-script
    


    
    Tenga en cuenta que AllowOverride Options y 
    AllowOverride FileInfo deben estar ambas activadas para que 
    estas directivas tengan efecto.
    

    
    Por favor vea el tutorial CGI para mayor detalle
    sobre programación y configuración de CGI.
    


    top
    

    

    Resolución de problemas
    

    
    Cuando pone directivas en un fichero .htaccess y no obtiene 
    el efecto deseado hay una serie de cosas que pueden haber ido mal.
    

    
    El problema más común es que AllowOverride
     no está configurada para que sus directivas puedan surtir
    efecto. Asegúrese de que no tiene AllowOverride None 
    configurado para el directorio en cuestión. Una buena forma de probar esto
    es poner "basura" en su fichero .htaccess y recargar la página. 
    Si no se genera un error en el servidor, casi seguro que tiene configurado 
    AllowOverride None.
    

    
    Si, por otro lado, obtiene errores de servidor al intentar acceder a 
    documentos, compruebe el log de errores de httpd. Seguramente le indiquen 
    que la directiva en uso en su fichero .htaccess no está 
    permitida.
    

    
    
    [Fri Sep 17 18:43:16 2010] [alert] [client 192.168.200.51] /var/www/html/.htaccess: DirectoryIndex not allowed here
    
    

    
    Esto indicará que o bien ha usado una directiva que no se permite nunca 
    en ficheros .htaccess, o que simplementa no tiene
    AllowOverride configurado
    a un nivel suficiente para la directiva que ha usado. Consulte la
    documentación para esa directiva en particular para determinar cual es el 
    caso.
    

    
    Alternativamente, puede que le indique que hay un error de sintaxis en 
    el uso de la propia directiva.
    

    
    
    [Sat Aug 09 16:22:34 2008] [alert] [client 192.168.200.51] /var/www/html/.htaccess: RewriteCond: bad flag delimiters
    
    

    
    En este caso, el mensaje de error debería ser específico para el error de
    sintaxis concreto que ha cometido.

    Authentication is any process by which you verify that
    someone is who they claim they are. Authorization is any
    process by which someone is allowed to be where they want to
    go, or to have information that they want to have.

    Control How-To.

    Related Modules and Directives
    


    There are three types of modules involved in the authentication and
authorization process.  You will usually need to choose at least one
module from each group.
    



  
    In addition to these modules, there are also
  mod_authn_core and
  mod_authz_core.  These modules implement core
  directives that are core to all auth modules.
    

  
    The module mod_authnz_ldap is both an
  authentication and authorization provider.  The module
  mod_authz_host provides authorization
  and access control based on hostname, IP address or characteristics
  of the request, but is not part of the authentication provider
  system. For backwards compatibility with the mod_access, there is
  a new module mod_access_compat.
    

  
    You probably also want to take a look at the Access Control howto, which discusses the
  various ways to control access to your server.

    Introduction
    
    
    If you have information on your web site that is sensitive
    or intended for only a small group of people, the techniques in
    this article will help you make sure that the people that see
    those pages are the people that you wanted to see them.
    

    
    This article covers the "standard" way of protecting parts
    of your web site that most of you are going to use.
    

    
    Note:
    
    
    If your data really needs to be secure, consider using
    mod_ssl in addition to any authentication.
    
    
    

    top
    

    

    The Prerequisites
    
    
    The directives discussed in this article will need to go
    either in your main server configuration file (typically in a
    <Directory> section), or
    in per-directory configuration files (.htaccess files).
    

    
    If you plan to use .htaccess files, you will
    need to have a server configuration that permits putting
    authentication directives in these files. This is done with the
    AllowOverride directive, which
    specifies which directives, if any, may be put in per-directory
    configuration files.
    

    
    Since we're talking here about authentication, you will need
    an AllowOverride directive like the
    following:
    

    
    AllowOverride AuthConfig
    


    
    Or, if you are just going to put the directives directly in
    your main server configuration file, you will of course need to
    have write permission to that file.
    

    
    And you'll need to know a little bit about the directory
    structure of your server, in order to know where some files are
    kept. This should not be terribly difficult, and I'll try to
    make this clear when we come to that point.
    

    
    You will also need to make sure that the modules
    mod_authn_core and mod_authz_core
    have either been built into the httpd binary or loaded by the
    httpd.conf configuration file. Both of these modules provide core
    directives and functionality that are critical to the configuration
    and use of authentication and authorization in the web server.

    Getting it working
    
    
    Here's the basics of password protecting a directory on your
    server.
    

    
    First, you need to create a password file. Exactly how you do
    this will vary depending on what authentication provider you have
    chosen. More on that later. To start with, we'll use a text password
    file.
    

    
    This file should be
    placed somewhere not accessible from the web. This is so that
    folks cannot download the password file. For example, if your
    documents are served out of /usr/local/apache/htdocs, you
    might want to put the password file(s) in
    /usr/local/apache/passwd.
    

    
    To create the file, use the htpasswd utility that
    came with Apache. This will be located in the bin directory
    of wherever you installed Apache. If you have installed Apache from
    a third-party package, it may be in your execution path.
    

    
    To create the file, type:
    

    
    
      htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
    

    
    htpasswd will ask you for the password, and
    then ask you to type it again to confirm it:
    

    
    
      # htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
      New password: mypassword
    
      Re-type new password: mypassword
    
      Adding password for user rbowen
    
    

    
    If htpasswd is not in your path, of course
    you'll have to type the full path to the file to get it to run.
    With a default installation, it's located at
    /usr/local/apache2/bin/htpasswd
    

    
    Next, you'll need to configure the server to request a
    password and tell the server which users are allowed access.
    You can do this either by editing the httpd.conf
    file or using an .htaccess file. For example, if
    you wish to protect the directory
    /usr/local/apache/htdocs/secret, you can use the
    following directives, either placed in the file
    /usr/local/apache/htdocs/secret/.htaccess, or
    placed in httpd.conf inside a <Directory
    "/usr/local/apache/htdocs/secret"> section.
    

    
    AuthType Basic
AuthName "Restricted Files"
# (Following line optional)
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
Require user rbowen
    


    
    Let's examine each of those directives individually. The AuthType directive selects
    the method that is used to authenticate the user. The most
    common method is Basic, and this is the method
    implemented by mod_auth_basic. It is important to be aware,
    however, that Basic authentication sends the password from the client to
    the server unencrypted. This method should therefore not be used for
    highly sensitive data, unless accompanied by mod_ssl.
    Apache supports one other authentication method:
    AuthType Digest. This method is implemented by mod_auth_digest and was intended to be more secure. This is no
    longer the case and the connection should be encrypted with mod_ssl instead.
    

    
    The AuthName directive sets
    the Realm to be used in the authentication. The realm serves
    two major functions. First, the client often presents this information to
    the user as part of the password dialog box. Second, it is used by the
    client to determine what password to send for a given authenticated
    area.
    

    
    So, for example, once a client has authenticated in the
    "Restricted Files" area, it will automatically
    retry the same password for any area on the same server that is
    marked with the "Restricted Files" Realm.
    Therefore, you can prevent a user from being prompted more than
    once for a password by letting multiple restricted areas share
    the same realm. Of course, for security reasons, the client
    will always need to ask again for the password whenever the
    hostname of the server changes.
    

    
    The AuthBasicProvider is,
    in this case, optional, since file is the default value
    for this directive. You'll need to use this directive if you are
    choosing a different source for authentication, such as
    mod_authn_dbm or mod_authn_dbd.
    

    
    The AuthUserFile
    directive sets the path to the password file that we just
    created with htpasswd. If you have a large number
    of users, it can be quite slow to search through a plain text
    file to authenticate the user on each request. Apache also has
    the ability to store user information in fast database files.
    The mod_authn_dbm module provides the AuthDBMUserFile directive. These
    files can be created and manipulated with the dbmmanage and htdbm programs. Many
    other types of authentication options are available from third
    party modules.
    

    
    Finally, the Require
    directive provides the authorization part of the process by
    setting the user that is allowed to access this region of the
    server. In the next section, we discuss various ways to use the
    Require directive.
    

    top
    

    

    Letting more than one
person in
    
    
    The directives above only let one person (specifically
    someone with a username of rbowen) into the
    directory. In most cases, you'll want to let more than one
    person in. This is where the AuthGroupFile comes in.
    

    
    If you want to let more than one person in, you'll need to
    create a group file that associates group names with a list of
    users in that group. The format of this file is pretty simple,
    and you can create it with your favorite editor. The contents
    of the file will look like this:
    

   
    
     GroupName: rbowen dpitts sungo rshersey
   
    

    
    That's just a list of the members of the group in a long
    line separated by spaces.
    

    
    To add a user to your already existing password file,
    type:
    

    
    
      htpasswd /usr/local/apache/passwd/passwords dpitts
    
    

    
    You'll get the same response as before, but it will be
    appended to the existing file, rather than creating a new file.
    (It's the -c that makes it create a new password
    file).
    

    
    Now, you need to modify your .htaccess file or
    <Directory> block
    to look like the following:
    

    
    AuthType Basic
AuthName "By Invitation Only"
# Optional line:
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
AuthGroupFile "/usr/local/apache/passwd/groups"
Require group GroupName
    


    
    Now, anyone that is listed in the group GroupName,
    and has an entry in the password file, will be let in, if
    they type the correct password.
    

    
    There's another way to let multiple users in that is less
    specific. Rather than creating a group file, you can just use
    the following directive:
    

    
    Require valid-user
    


    
    Using that rather than the Require user rbowen
    line will allow anyone in that is listed in the password file,
    and who correctly enters their password.
    

    top
    

    

    Possible problems
    
    
    Because of the way that Basic authentication is specified,
    your username and password must be verified every time you
    request a document from the server. This is even if you're
    reloading the same page, and for every image on the page (if
    they come from a protected directory). As you can imagine, this
    slows things down a little. The amount that it slows things
    down is proportional to the size of the password file, because
    it has to open up that file, and go down the list of users
    until it gets to your name. And it has to do this every time a
    page is loaded.
    

    
    A consequence of this is that there's a practical limit to
    how many users you can put in one password file. This limit
    will vary depending on the performance of your particular
    server machine, but you can expect to see slowdowns once you
    get above a few hundred entries, and may wish to consider a
    different authentication method at that time.
    

    top
    

    

    Alternate password storage
    

    
    Because storing passwords in plain text files has the above
    problems, you may wish to store your passwords somewhere else, such
    as in a database.
    

    
    mod_authn_dbm and mod_authn_dbd are two
    modules which make this possible. Rather than selecting AuthBasicProvider file, instead
    you can choose dbm or dbd as your storage
    format.
    

    
    To select a dbm file rather than a text file, for example:
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider dbm
    AuthDBMUserFile "/www/passwords/passwd.dbm"
    Require valid-user
</Directory>
    


    
    Other options are available. Consult the
    mod_authn_dbm documentation for more details.
    

    top
    

    

    Using multiple providers
    

    
    With the introduction of the new provider based authentication and
    authorization architecture, you are no longer locked into a single
    authentication or authorization method. In fact any number of the
    providers can be mixed and matched to provide you with exactly the
    scheme that meets your needs. In the following example, both the
    file and LDAP based authentication providers are being used.
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file ldap
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    Require valid-user
</Directory>
    


    
    In this example the file provider will attempt to authenticate
    the user first. If it is unable to authenticate the user, the LDAP
    provider will be called. This allows the scope of authentication
    to be broadened if your organization implements more than
    one type of authentication store. Other authentication and authorization
    scenarios may include mixing one type of authentication with a
    different type of authorization. For example, authenticating against
    a password file yet authorizing against an LDAP directory.
    

    
    Just as multiple authentication providers can be implemented, multiple
    authorization methods can also be used. In this example both file group
    authorization as well as LDAP group authorization is being used.
    

    
    <Directory "/www/docs/private">
    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    AuthGroupFile "/usr/local/apache/passwd/groups"
    Require group GroupName
    Require ldap-group cn=mygroup,o=yourorg
</Directory>
    


    
    To take authorization a little further, authorization container
    directives such as
    <RequireAll>
    and
    <RequireAny>
    allow logic to be applied so that the order in which authorization
    is handled can be completely controlled through the configuration.
    See Authorization
    Containers for an example of how they may be applied.
    


    top
    

    

    Beyond just authorization
    

    
    The way that authorization can be applied is now much more flexible
    than just a single check against a single data store. Ordering, logic
    and choosing how authorization will be done is now possible.
    

    
    Applying logic and ordering
    
        
    Controlling how and in what order authorization will be applied
        has been a bit of a mystery in the past. In Apache 2.2 a provider-based
        authentication mechanism was introduced to decouple the actual
        authentication process from authorization and supporting functionality.
        One of the side benefits was that authentication providers could be
        configured and called in a specific order which didn't depend on the
        load order of the auth module itself. This same provider based mechanism
        has been brought forward into authorization as well. What this means is
        that the Require directive
        not only specifies which authorization methods should be used, it also
        specifies the order in which they are called. Multiple authorization
        methods are called in the same order in which the
        Require directives
        appear in the configuration.
    

        
    With the introduction of authorization container directives
        such as
        <RequireAll>
        and
        <RequireAny>,
        the configuration also has control over when the
        authorization methods are called and what criteria determines when
        access is granted.  See
        Authorization Containers
        for an example of how they may be used to express complex
        authorization logic.
    

        
    By default all
        Require
        directives are handled as though contained within a
        <RequireAny>
        container directive.  In other words, if
        any of the specified authorization methods succeed, then authorization
        is granted.
    

    

    
    Using authorization providers for access control
    
        
    Authentication by username and password is only part of the
        story. Frequently you want to let people in based on something
        other than who they are. Something such as where they are
        coming from.
    

        
    The authorization providers all,
        env, host and ip let you
        allow or deny access based on other host based criteria such as
        host name or ip address of the machine requesting a
        document.
    

        
    The usage of these providers is specified through the
        Require directive.
        This directive registers the authorization providers
        that will be called during the authorization stage of the request
        processing. For example:
    

        
    Require ip address
        
    


        
    where address is an IP address (or a partial IP
        address) or:
    

        
    Require host domain_name
        
    


        
    where domain_name is a fully qualified domain name
        (or a partial domain name); you may provide multiple addresses or
        domain names, if desired.
    

        
    For example, if you have someone spamming your message
        board, and you want to keep them out, you could do the
        following:
    

        
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>
    


        
    Visitors coming from that address will not be able to see
        the content covered by this directive. If, instead, you have a
        machine name, rather than an IP address, you can use that.
    

        
    <RequireAll>
    Require all granted
    Require not host host.example.com
</RequireAll>
    


        
    And, if you'd like to block access from an entire domain,
        you can specify just part of an address or domain name:
    

        
    <RequireAll>
    Require all granted
    Require not ip 192.168.205
    Require not host phishers.example.com moreidiots.example
    Require not host ke
</RequireAll>
    


        
    Using <RequireAll>
        with multiple <Require> directives, each negated with not,
        will only allow access, if all of negated conditions are true. In other words,
        access will be blocked, if any of the negated conditions fails.
    

    

    
    Access Control backwards compatibility
    
        
    One of the side effects of adopting a provider based mechanism for
        authentication is that the previous access control directives
        Order,
        Allow,
        Deny and
        Satisfy are no longer needed.
        However to provide backwards compatibility for older configurations, these
        directives have been moved to the mod_access_compat module.
    

        
    Note
    
        
    The directives provided by mod_access_compat have
        been deprecated by mod_authz_host.
        Mixing old directives like Order, Allow or Deny with new ones like
        Require is technically possible
        but discouraged. The mod_access_compat module was created to support
        configurations containing only old directives to facilitate the 2.4 upgrade.
        Please check the upgrading guide for more
        information.

    Authentication Caching
    
    
    There may be times when authentication puts an unacceptable load
    on a provider or on your network.  This is most likely to affect users
    of mod_authn_dbd (or third-party/custom providers).
    To deal with this, HTTPD 2.3/2.4 introduces a new caching provider
    mod_authn_socache to cache credentials and reduce
    the load on the origin provider(s).
    
    
    This may offer a substantial performance boost to some users.
    

    top
    

    

    More information
    
    
    You should also read the documentation for
    mod_auth_basic and mod_authz_host
    which contain some more information about how this all works.  The
    directive <AuthnProviderAlias> can also help
    in simplifying certain authentication configurations.
    

    
    The various ciphers supported by Apache for authentication data are
    explained in Password
    Encryptions.
    

    
    And you may want to look at the Access
    Control howto, which discusses a number of related topics.

    Introducción
    
 
    Módulos RelacionadosDirectivas Relacionadas
    

    
    Este artículo trata sobre los Server Side Includes, generalmente llamados SSI.
     En este artículo, hablaremos sobre cómo configurar su servidor para permitir SSI,
      y de técnicas básicas de SSI para añadir contenido dinámico a sus páginas 
      HTML existentes.
    

    
    Más adelante también hablaremos de algunas técnicas más avanzadas que 
    pueden usarse con SSI, tales como declaraciones condicionales en sus directivas SSI.
    


    top
    

    

    ¿Qué son los SSI?
    

    
    SSI (Server Side Includes) son directivas que se introducen en páginas HTML y son 
        evaluadas por el servidor mientras éste las sirve. Le permiten añadir 
        contenido generado de manera dinámica a sus páginas HTML existentes sin tener 
        que servir una página entera a través de un programa CGI, u otra tecnología 
        para generar contenido dinámico.
    

    
    Por ejemplo, podría colocar una directiva en una página existente de HTML 
        de esta manera:
    

    
    
    <!--#echo var="DATE_LOCAL" -->
    
    

    
    Y, cuando se sirve la página, este fragmento será evaluado y sustituido con su resultado:
    

    
    
    Tuesday, 15-Jan-2013 19:28:54 EST
    
    

    
    La decisión sobre cuándo usar SSI, o de cuándo generar una página al completo con algún programa, suele depender generalmente de la cantidad de contenido estático que contiene, y cuánto de esa página tiene que ser recalculado cada vez que ésta se sirve. SSI es un buen método para añadir pequeñas partes de información, tales como la hora actual - como se ha mostrado más arriba. Pero si la mayoría de su página se tiene que generar en el momento en el que se está sirviendo, necesita buscar otra opción más adecuada que no sea SSI.
    

    top
    

    

    Configurar su servidor para permitir SSI
    


    
    Para permitir SSI en su servidor, debe tener la siguiente directiva en su fichero httpd.conf , o en un fichero 
    .htaccess:
    

    Options +Includes
    


    
    Esto le dice a Apache que quiere permitir que se examinen los ficheros buscando directivas SSI. Tenga en cuenta que la mayoría de las configuraciones contienen múltiples directivas Options que pueden sobreescribirse las unas a las otras. Probablemente necesitará aplicar Options al directorio específico donde quiere SSI activado para asegurarse de que se evalúa en último lugar y por tanto se acabará aplicando.
    

    
    No todos los ficheros se examinan buscando directivas SSI. Usted Le tiene que indicar a Apache qué ficheros se tienen que examinar. Hay dos formas de hacer esto. Puede decirle a Apache que examine cualquier fichero con una extensión determinada, como por ejemplo .shtml, con las siguientes directivas:
    

    AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
    


    
    Una desventaja de este método es que si quisiera añadir directivas SSI a una página ya existente, tendría que cambiar el nombre de la página, y todos los enlaces que apuntasen a esa página, todo para poder darle la extensión .shtml y que esas directivas sean interpretadas.
    

    
    El otro método es usar la directiva XBitHack :
    

    XBitHack on
    


    
    XBitHack le dice a Apache que examine ficheros buscando directivas SSI si los ficheros tienen el bit de ejecución configurado. Asi que para añadir directivas SSI a una página existente, en lugar de tener que cambiarle el nombre, solo tendría que convertirla en ejecutable usando chmod.
    

    
        chmod +x pagename.html

    

    
    Una breve recomendación de qué no hay que hacer. Ocasionalmente vemos gente recomendar que le diga a Apache que examine todos los ficheros 
    .html para activar SSI, para no tener que lidiar renombrando los ficheros a .shtml. Quizás estas personas no hayan oido hablar de XBitHack. Lo que hay que tener en cuenta, es que haciendo eso, está pidiendo al Apache que lea cada uno de los ficheros que manda al cliente, incluso si no contenien directivas SSI. Esto puede ralentizar bastante el servidor, y no es una buena idea.
    

    
    Por supuesto, en Windows, no hay tal cosa como la configuración del bit de ejecución, así que esto limita las opciones un poco.
    

    
    En su configuración por defecto, Apache no envía la fecha de última modificación o la longitud de contenido de páginas SSI porque es dificil calcular estos valores para contenido dinámico. Esto puede impedir que se cachee un documento, y dar como resultado en apareciencia un rendimiento más lento del cliente. Hay dos maneras de solucionar esto:
    

    
      
      
    1. Usando la configuración XBitHack Full. Esto le indica a apache que determine la fecha de última modificación mirando sólo la fecha del fichero que se ha solicitado originalmente, obviando la modificación de cualquier otro fichero al que se hace referencia mediante SSI.
      2. 

      
    2. Use las directivas facilitadas por mod_expires para configurar una expiración específica de tiempo en sus ficheros, y así hacer saber a proxies o navegadores web que es aceptable cachearlos.
      3. 
    
    

    top
    

    

    Directivas SSI básicas
    

    
    Las directivas SSI tienen la sintaxis siguiente:
    

    
        <!--#function attribute=value attribute=value ... -->

    

    
    Se formatean como comentarios HTML, así si no tiene SSI habilitado correctamente, el navegador las obviará, pero todavía serán visibles en el fichero HTML. Si tiene SSI configurado correctamente, la directiva será reemplazada con su propio resultado.
    

    
    Esta función es una de tantas, y hablaremos de algunas de ellas más adelante. Por ahora, aquí mostramos unos ejemplos de lo que puede hacer con SSI.
    


    La fecha de hoy
    


    
        <!--#echo var="DATE_LOCAL" -->

    

    
    La función echo sencillamente muestra el valor de una variable. Hay muchas variables estándar que incluyen un conjunto de variables de entorno disponibles para programas CGI. También puede definir sus propias variables con la función set.
    

    
    Si no le gusta el formato en el que se imprime la fecha, puede usar la función config, con un atributo
    timefmt para modificar ese formato.
    


    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        Today is <!--#echo var="DATE_LOCAL" -->

    



    Fecha de modificación del fichero
    


    
        La última modificación de este documento <!--#flastmod file="index.html" -->

    

    
    Esta función también está sujeta a configuraciones de formato de 
        timefmt.
    



    Incluyendo los resultados de un programa CGI
    

    
    Este es uno de los usos más comunes de SSI - para sacar el resultado de un programa CGI, tal y como ocurre con el que fuera el programa favorito de todos, un ``contador de visitas.''
    


    
        <!--#include virtual="/cgi-bin/counter.pl" -->

    



    top
    

    

    Más ejemplos
    


    
    A continuación hay algunos ejemplos específicos de cosas que puede hacer con SSI en sus documentos HTML.
    


    ¿Cuándo fue modificado este documento?
    

    
    Antes mencionamos que puede usar SSI para informar al usuario cuando el documento ha sido modificado por última vez. Aun así, el método actual para hacerlo se dejó en cuestión. El código que se muestra a continuación, puesto en un documento HTML, pondrá ese sello de tiempo en su página. Por descontado, tendrá que tener SSI habilitado correctamente, como se indicó más arriba.
    

    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        Ultima modificación de este fichero <!--#flastmod file="ssi.shtml" -->

    

    
    Obviamente, necesitará sustituir el nombre de fichero
    ssi.shtml con el nombre real del fichero al que usted hace referencia. Esto puede ser inconveniente si solo está buscando un trozo genérico de código que pueda copiar y pegar en cualquier fichero, asi que probablemente necesite usar la variable LAST_MODIFIED en su lugar:
    

    
        <!--#config timefmt="%D" -->
    
        Última modificación de este fichero <!--#echo var="LAST_MODIFIED" -->

    

    
    Para más detalles sobre el formato timefmt, vaya a su buscador favorito y busque strftime. La sintaxis es la misma.
    



    Incluyendo un pie de página estándar
    


    
    Si gestiona un sitio que tiene más de unas cuantas páginas, probablemente se de cuenta de que modificar todas esa páginas es un auténtico engorro, especialmente si trata de mantener una apareciencia homogénea en todas ellas.
    

    
    Si usa un Include de fichero para la cabecera y/o pie de página puede reducir la carga de trabajo de estas actualizaciones. Solo tiene que hacer un sólo pie de página, y después incluirlo en cada página con el comando SSI include. La función include
    puede determinar qué fichero incluir cuando usa el atributo
    file, o el atributo virtual. El atributo file es una ruta de fichero, relativa al directorio actual. Eso significa que no puede ser una ruta de fichero absoluta (que comienza con /), ni tampoco puede contener ../ como parte de la ruta. El atributo virtual es probablemente más útil, y debería especificar una URL relativa al documento que se está sirviendo. Puede empezar con una /, pero debe estar en el mismo servidor que el fichero que se está sirviendo.
    

    
        <!--#include virtual="/footer.html" -->

    

    
    Frecuentemente combinaremos las dos últimas, poniendo una directiva
    LAST_MODIFIED dentro de un fichero de pie de página que va a ser incluido. Se pueden encontrar directivas SSI en el fichero que se incluye, las inclusiones pueden anidarse - lo que quiere decir, que el fichero incluido puede incluir otro fichero, y así sucesivamente.
    



    top
    

    

    ¿Qué más puedo configurar?
    


    
    Además de poder configurar el formato de la hora, también puede configurar dos cosas más.
     

    
    Generalmente, cuando algo sale mal con sus directivas SSI, obtiene el mensaje (ha ocurrido un error procesando esta directiva)
    

    
        [an error occurred while processing this directive]

    

    
    Si quiere cambiar ese mensaje por otra cosa, puede hacerlo con el atributo errmsg para la función
    config:
    

    
        <!--#config errmsg="[Parece que no sabe cómo usar SSI]" -->

    

    
    Afortunadamente, los usuarios finales nunca verán este mensaje, porque habrá resuelto todos los problemas con sus directivas SSI antes de publicar su página web. (¿Verdad?)
    

    
    Y puede configurar el formato en el que los tamaños de fichero se muestran con el formato sizefmt. Puede especificar
    bytes para un recuento total en bytes, o
    abbrev para un número abreviado en Kb o Mb, según sea necesario.
    
    
    top
    

    

    Ejecutando comandos
    
    

    
     Puede usar la función exec para ejecutar comandos. Y SSI puede ejecutar un comando usando la shell (/bin/sh, para ser más precisos - o la shell de DOS , si está en Win32). Lo siguiente, por ejemplo, le dará un listado de ficheros en un directorio.
    

    
        <pre>
    
        <!--#exec cmd="ls" -->
    
        </pre>

    

    
    o, en Windows
    

    
        <pre>
    
        <!--#exec cmd="dir" -->
    
        </pre>

    

    
    Notará un formato estraño con esta directiva en Windows, porque el resultado de dir contiene la cadena de caracterers ``<dir>'' ,que confunde a los navegadores.
    

    
    Tenga en cuenta de que esta característica es muy peligrosa, puesto que ejecutará cualquier código que esté especificado con la etiqueta 
    exec. Si tiene una situación en la que los usuarios pueden editar contenido en sus páginas web, tales como por ejemplo un ``registro de visitas'', asegúrese de tener esta característica deshabilitada. Puede permitir SSI, pero no la característica exec, con el argumento IncludesNOEXEC en la directiva Options.
    
    
    top
    

    

    Técnicas avanzadas de SSI
    


    
    Además de mostrar contenido, SSI en Apache da la opción de configurar variables y usar esas variables en comparaciones y condicionales.
    


    Configurando Variables
    

    
    Usando la directiva set, puede configurar variables para su uso posterior. La sintaxis es como sigue:
    

    
        <!--#set var="name" value="Rich" -->

    

    
    Además de configurar valores literales como esto, puede usar cualquier otra variable, incluyendo variables de entorno o las variables que se han mencionado antes (como por ejemplo LAST_MODIFIED) para dar valores a sus variables. Podrá especificar que algo es una vaiable, en lugar de una cadena de caracters literal, usando el símbolo del dolar ($) antes del nombre de la variable.
    

    
     <!--#set var="modified" value="$LAST_MODIFIED" -->
    
    

    
    Para poner el símbolo del dolar de manera literal en un valor de su variable tendrá que escapar el símbolo del dolar con una barra "\".
    

    
        <!--#set var="cost" value="\$100" -->

    

    
    Por último, si quiere poner una variable entre medias de una cadena de caracteres más larga, y se da la coincidencia de que el nombre de la variable se encontrará con otros caracteres, y de esta manera se confundirá con otros caracteres, puedes poner el nombre de la variable entre llaves, y así eliminar la confusión. (Es dificil encontrar un buen ejemplo para esto, pero con éste a lo mejor entiende lo que tratamos de transmitir.)
    

    
        <!--#set var="date" value="${DATE_LOCAL}_${DATE_GMT}" -->

    



    Expresiones condicionales
    


    
    Ahora que tenemos variables, y somos capaces de comparar sus valores, podemos usarlas para expresar condicionales. Esto permite a SSI ser un cierto tipo de lenguaje de programación diminuto.
    mod_include provee una estrucura if,
    elif, else, endif
    para construir declaraciones condicionales. Esto le permite generar de manera efectiva multitud de páginas lógicas desde tan solo una página.
    

    
    La estructura de este sistema condicional es:
    

    
    <!--#if expr="test_condition" -->
    
    <!--#elif expr="test_condition" -->
    
    <!--#else -->
    
    <!--#endif -->

    

    
    Una test_condition puede ser cualquier tipo de comparación lógica - o bien comparando valores entre ellos, o probando la ``verdad'' (o falsedad) de un valor en particular. (Una cadena de caracteres cualquiera es verdadera si no está vacía.) Para una lista completa de operadores de comparación, vea la documentación de mod_include.
    

    
    Por ejemplo, si quiere personalizar el texto en su página web basado en la hora actual, puede usar la siguiente receta, colocada en su página HTML:
    

    
    
    Good
    <!--#if expr="%{TIME_HOUR} <12" -->
    
    morning!
    
    <!--#else -->
    
    afternoon!
    
    <!--#endif -->
    
    
    

    
    Cualquier otra variable (o bien las que defina usted, o variables de entorno normales) puede usarse en declaraciones condicionales.
    Vea Expresiones en el Servidor Apache HTTP para más información sobre el motor de evaluación de expresiones.
    

    
    Con la habilidad de Apache de configurar variables de entorno con directivas SetEnvIf, y otras directivas relacionadas,
    esta funcionalidad puede llevarle a hacer una gran variedad de contenido dinámico en la parte de servidor sin tener que depender de una aplicación web al completo.
    


    top
    

    

    Conclusión
    

    
    Desde luego SSI no es un reemplazo para CGI u otras tecnologías que se usen para generar páginas web dinámicas. Pero es un gran método para añadir pequeñas cantidaddes de contenido dinámico a páginas web, sin hacer mucho más trabajo extra.

    関連モジュール関連ディレクティブ
    

    
    CGI (Common Gateway Interface) は、ウェブサーバが
    コンテンツ生成をする外部プログラムと協調して動作するための方法を
    定義しています。そのプログラムはしばしば CGI プログラムや
    CGI スクリプトと呼ばれます。CGI は、ウェブサイトに動的な
    コンテンツを置くための最も簡単で一般的な方法です。このドキュメントは、
    Apache ウェブサーバで CGI を設定し、
    CGI プログラムを書き始めるための入門書となるでしょう。

    CGI を許可するように Apache を設定する
    
    

    
    CGI プログラムを正しく動作させるには、CGI を許可するように
    Apache の設定を行う必要があります。
    これを行なうための方法がいくつかあります。
    

    
    
    注: Apache が共有モジュール機能着きでビルドされている場合、
    モジュールがロードされていることを確認してください。
    つまり httpd.conf で 
    LoadModule
    がコメントアウトされていないことを確認してください。
    正常に設定されていれば次のようになるはずです:

    
    
      LoadModule cgi_module modules/mod_cgi.so
    
    

    
    ScriptAlias
    
      

      
    ScriptAlias
      ディレクティブを使用して、
      CGI プログラム用の特別な別ディレクトリを Apache に設定します。
      Apache は、このディレクトリ中の全てのファイルを CGI
      プログラムであると仮定します。
      そして、この特別なリソースがクライアントから要求されると、
      そのプログラムの実行を試みます。
    

      
    ScriptAlias
      ディレクティブは以下のように使用します:
    

      
    
        ScriptAlias /cgi-bin/ /usr/local/apache2/cgi-bin/
      
    

      
    デフォルト位置に Apache をインストールしたならば、
      この例はデフォルト状態の httpd.conf
      設定ファイルに含まれています。
      ScriptAlias
      ディレクティブは、URL の前に付加するディレクトリを定義する
      Alias
      ディレクティブとかなり似ています。
      Alias と ScriptAlias
      は通常、DocumentRoot
      ディレクトリ外のディレクトリのために使用されます。
      Alias と ScriptAlias
      との差は、ScriptAlias が接頭辞で始まるすべての
      URL は CGI プログラムとみなされるという追加の意味を含んでいることです。
      従って、上記の例では、/cgi-bin/
      で始まるリソースへのあらゆるリクエストに対して、ディレクトリ
      /usr/local/apache2/cgi-bin/ から提供し、それらを
      CGI プログラムとして扱うよう Apache に示します。
    

      
    例えば、URL http://www.example.com/cgi-bin/test.pl
      が要求された場合、Apache は ファイル
      /usr/local/apache2/cgi-bin/test.pl
      を実行し、その出力を返すことを試みます。
      もちろん、ファイルが存在し、実行可能であり、決められた方法で出力を返します。
      そうでなければ、Apache はエラーメッセージを返します。
    
    

    
    ScriptAlias ディレクトリ外の CGI
    
      

      
    CGI プログラムは、セキュリティ上の理由から 
      ScriptAlias
      されたディレクトリに制限されることがしばしばあります。この方法により、
      CGI プログラムを使用できるユーザを管理者が厳しく制御することができます。
      しかしながら、適切なセキュリティ事前対策がとられるならば、CGI
      プログラムを任意のディレクトリで実行できないようにする理由はありません。
      例えば、ユーザに UserDir
      ディレクティブで彼らのホームディレクトリ配下にウェブコンテンツを持たせたいとします。
      もし、彼らが CGI プログラムを持つことを望んでいても、メインの
      cgi-bin ディレクトリへのアクセスができない場合、
      CGI プログラムを実行することができる他の場所が必要になります。
    

      
    任意のディレクトリで CGI の実行を許可するには二段階の設定が必要です。
      まず、AddHandler や SetHandler ディレクティブによって
      cgi-script ハンドラが可能になっている必要があります。
      次に、Options ディレクティブで
      ExecCGI が指定されていなければなりません。
    
    

    
    CGI の実行を可能にするために Options を明示的に使用する
    
      

      
    サーバのメインの設定ファイル中で Options
      ディレクティブを明示的に使用することで、特定のディレクトリ配下で
      CGI の実行を許可するように指定することができます:
    

      
    
        <Directory /usr/local/apache2/htdocs/somedir>
    
        
          Options +ExecCGI
    
            
        </Directory>
      
    

      
    上記ディレクティブは、CGI ファイルの実行を可能にするよう
      Apache に伝えます。また、どのファイルが CGI ファイルかを
      サーバに伝える必要があります。次の
      AddHandler
      ディレクティブの例では、cgi または pl
      を拡張子に持つすべてのファイルを CGI
      プログラムとしてみなすことをサーバに伝えます:
    

      
    
        AddHandler cgi-script .cgi .pl
      
    
    

    
    .htaccess ファイル
    
      

      
    .htaccess チュートリアル
      は httpd.conf を変更できない場合にどうやって CGI プログラムを
      使えるようにするかを説明しています。
    
    

    
    User ディレクトリ
    
      

      
    .cgi で終わるすべてのファイルに対して CGI プログラムの
      実行を許可するには、以下の設定を使用できます。
    

      
    
      <Directory /home/*/public_html>
    
      
        Options +ExecCGI
    
        AddHandler cgi-script .cgi
    
          
      </Directory>
      
    

      
    ユーザディレクトリの cgi-bin サブディレクトリの
      すべてのファイルを CGI プログラムとして指定したい場合には
      以下のようなものを使います。
    

      
    
      <Directory /home/*/public_html/cgi-bin>
    
      
        Options ExecCGI
    
        SetHandler cgi-script
    
          
      </Directory>
      
    

    
  
    top
    

    

    CGI プログラムを書く
    
    

    
    「通常の」プログラミングと CGI
    プログラミングの間には主に二つの違いがあります。
    

    
    一つは、CGI プログラムのすべての出力にはMIME タイプ
    ヘッダを付けなければなりません。
    これはどのような種類のコンテンツを受け取っているかをクライアントに示す
    HTTP ヘッダです。ほとんどの場合では、次のように出力します:
    

    
    
      Content-type: text/html
    
    

    
    もう一つは、出力を HTML
    か、ブラウザが表示することができる何か他の形式にする必要があります。
    大抵の場合は HTML でしょうが、GIF イメージや他の非 HTML
    コンテンツを出力する CGI プログラムを書くこともあるでしょう。
    

    
    これら二点以外では、CGI プログラムを書くことは、
    あなたが書いている他のプログラムとよく似ているでしょう。
    

    
    最初の CGI プログラム
    
      

      
    次に示すのは、ブラウザに 1 行印字する CGI
      プログラムの例です。以下を入力し、first.pl
      というファイルに保存し、それを cgi-bin
      ディレクトリに置いてください。
    

      
    
        #!/usr/bin/perl
    
        print "Content-type: text/html\n\n";
    
        print "Hello, World.";
      
    

      
    Perl に精通していなくても、
      何が起こるかを理解することはできるでしょう。1 行目は、
      /usr/bin/perl で見つけられるインタプリタに
      このファイルを供給することでこのプログラムが実行されることを
      Apache に (シェル上で実行しようとしているならば、そのシェルに ) 
      示します。2 行目は、前述したとおり content-type の定義を印字します。
      これには復帰改行の二つの組を後に付加します。
      これにより、ヘッダの終りに空行が置かれ、HTTP
      ヘッダの終りとボディの始まりを示します。3 行目は、"Hello, World."
      という文字列を印字し、これで終りとなります。
    

      
    好みのブラウザを開き、アドレス
    

      
    
        http://www.example.com/cgi-bin/first.pl
      
    

      
    あるいはファイルを置いたロケーションを指定すると、
      Hello, World.
      という 1 行がブラウザウィンドに現れるでしょう。
      それはあまりエキサイティングなことではありません。
      しかし、これがうまく動けば、
      他のどのようなものでも動かすことができるようになります。
    
    
  
    top
    

    

    しかし、まだ動かない !
    
    

    
    ウェブから CGI プログラムへのアクセスを行なったとき、
    ブラウザで見る可能性がある四つの基本的なことがあります:
    

    
    
      
    CGI プログラムの出力
    
      
    素晴らしい ! それはすべてがうまく動いたことを意味します。
      出力が正常だけれども、ブラウザが正常に処理してくれない場合は、
      正しい Content-Type を CGI プログラム内で
      セットしたかを確認してください。
    

      
    CGI プログラムのソースコード、または "POST Method Not Allowed"
      というメッセージ
     
      
    これは、CGI プログラムを処理できるよう Apache
      を適切に設定していなかったことを意味します。「CGI を許可するように
      Apache を設定する」の章を読み直し、
      あなたが何を間違えたかを探してみてください。
      
    

      
    メッセージが "Forbidden" で始まっている
    
      
    これはパーミッションの問題ということを意味します。
      Apache のエラーログと、後述の「ファイルのパーミッション」
      の章をチェックしてください。
      
    

      
    "Internal Server Error" というメッセージ
    
      
    Apache
      のエラーログをチェックすると、"Premature end of script headers"
      というログが記録されていると思います。そして、おそらく CGI
      プログラムによって生成されたエラーメッセージも記録されているでしょう。
      この場合、CGI プログラムが適切な
      HTTP ヘッダを出力できない原因を知るために、
      以下の各章でチェックしてみてください。
    
    
    

    
    ファイルのパーミッション
    
      

      
    サーバはあなたの権限で実行されていないのを忘れないように。
      つまり、起動するとき、サーバは特権をもたないユーザ - 通常 nobody
      や www の権限で実行されます。したがって、あなたが所有する
      ファイルを実行するには別のパーミッションが必要となります。
      通常、nobody が実行するのに十分なパーミッションを与える方法は、
      ファイルに誰でも実行可能とするパーミッションを与えることです:
    

      
    
        chmod a+x first.pl
      
    

      
    また、もしあなたのプログラムが他のファイルを読み書きするならば、
      それらのファイルは、これが可能となる正しいパーミッション
      を持っている必要があります。
    

    

    
    パス情報と環境
    
      

      
    コマンドラインからプログラムを実行するとき、
      意識しなくてもシェルに渡される情報があります。
      例えば、参照するファイルのためにどこを検索したらよいかを
      シェルに伝える PATH があります。
    

      
    プログラムが CGI プログラムとしてウェブサーバによって実行されるとき、
      それは同じ PATH ではないかもしれません。
      CGI プログラム内で呼び出すあらゆるプログラム
      (例えば、sendmail のようなもの) は、
      フルパスで指定する必要があるでしょう。それにより、CGI
      プログラムを実行しようとしたとき、
      シェルはそのようなプログラムを見つけることができます。
    

      
    同様なことは、スクリプトのインタプリタ (しばしば perl)
      へのパスで、CGI プログラムの 1 行目に次のように示されます:
    

      
    
        #!/usr/bin/perl
      
    

      
    これがインタープリタへの実際のパスであることを確認しておきます。
    
    

      
    また、CGI プログラムが他の環境変数に依存している場合は、その環境変数が
      Apache から渡されるようにする必要があります。
    

    
    プログラムエラー
    
      

      
    CGI
      プログラムが失敗するのは大抵、プログラム自身に問題がある場合です。
      一度 CGI の使い方を理解し、前述の二つの誤りを犯していないならば、
      まず間違いなくそうでしょう。ブラウザを使ってテストする前に
      まず確認することは、コマンドラインからプログラムが実行できることです。
      例えば、以下を実行してみてください:
    

      
    
      cd /usr/local/apache2/cgi-bin
    
      ./first.pl
      
    

      
    (perl インタプリタは呼ばないでください。
      シェルと Apache がスクリプトの最初の行の パス情報 を使って見つけます。)
    

      
    最初にプログラムから出力されるのは Content-Type を含み、
      後に空行の続く HTTP ヘッダでなければなりません。他のものが出力されている
      場合は、Apache はこのプログラムをサーバ経由で実行しようとしたときには
      Premature end of script headers エラーを出力します。詳細は
      上記の CGI プログラムを書く を読んでください。
    
    

    
    エラーログ
    
      

      
    エラーログは友達です。
      全てのうまくいかないことは、エラーログにメッセージを生成します。
      必ずそれを最初に見るべきです。
      もし、あなたがウェブサイトを主催している場所が
      エラーログの参照を許していないならば、きっと他のサイトで主催するべきです。
      エラーログの読み方を学ぶことで、ほとんど全ての問題が迅速に確認され、
      迅速に解決されるということが分かるでしょう。
    
    

    
    Suexec
    
      

      
    suexec サポートプログラムは
      バーチャルホストやユーザのホームディレクトリの場所に依って
      CGI プログラムを違うユーザ権限の下で走らせることを可能にします。
      Suexec の権限のチェックは非常に厳しく、それを満たさない場合は
      CGI プログラムが Premature end of script headers エラーで
      実行されません。
    

      
    suexec を使っているかどうかを調べためには apachectl
      -V を実行して、SUEXEC_BIN の場所を調べてください。
      Apache がそこに suexec のバイナリを発見した場合は、suexec が
      使用されます。
    

      
    suexec を完全に理解していない限り、使うべきではありません。
      suexec を無効にするには、SUEXEC_BIN から指されている
      suexec バイナリを削除 (か名前を変更) するだけです。
      suexec を読んだ後で、まだそれを
      使いたいのであれば、suexec -V を実行して suexec の
      ログファイルの位置を調べ、そのログファイルを使ってポリシー違反を
      見つけてください。
    
    
  
    top
    

    

    裏で何が起こっているのか?
    
    

    
    CGI プログラミングに習熟すると、
    裏で起こっていることについて更に理解することの役に立ちます。
    ブラウザとサーバがどのように相互通信するかについては特にそうです。
    なぜなら、"Hello, World."
    を印字するプログラムを書くことはおおいに結構ですが、
    それは特に有益ではありません。
    

    
    環境変数
    
      

      
    環境変数は、
      あなたがコンピュータを使うときに辺りに存在している値です。
      それらは、パス
      (コマンドをタイプしたときに実行する実際のファイルを探し出すところ)、
      ユーザ名、端末型などのような便利なものです。
      通常、普段使用している環境変数の完全なリストを調べるには、
      コマンドプロンプトで env を入力します。
    

      
    CGI の処理中、サーバとブラウザも環境変数を設定し、
      それにより相互に通信することができるようになります。
      その環境変数は、ブラウザタイプ (Netscape, IE, Lynx)、サーバタイプ
      (Apache, IIS, WebSite)、実行されている CGI
      プログラムの名前などです。
    

      
    これらの変数は CGI プログラマが使用できます。
      そして、それはクライアントとサーバの通信の話の半分です。
      必要な変数の完全なリストは http://hoohoo.ncsa.uiuc.edu/cgi/env.html にあります。
    

      
    以下の単純な Perl CGI
      プログラムは、渡される全ての環境変数を表示します。同様のプログラムは、
      Apache ディストリビューションの cgi-bin
      ディレクトリに二つ含まれています。
      いくつかの変数が必須であり、いくつかは任意であることに注意してください。
      そして、公式のリストにはないいくつかの変数が表示されているかもしれません。
      さらに、Apache はデフォルトで用意されている基本的なものに
      あなた自身の環境変数を加えるための、
      多くの異なる方法を用意してします。
    

      
    
        #!/usr/bin/perl
    
        print "Content-type: text/html\n\n";
    
        foreach $key (keys %ENV) {
    
        
          print "$key --> $ENV{$key}<br>";
    
            
        }
      
    
    

    
    STDIN と STDOUT
    
      

      
    サーバとクライアント間のもう一つの通信は、標準入力
      (STDIN)と標準出力 (STDOUT)
      を通じて行なわれます。通常の文脈において、STDIN
      はキーボードやプログラムが動作するために与えられるファイルを意味し、
      STDOUT は通常コンソールまたはスクリーンを意味します。
    

      
    ウェブフォームから CGI プログラムへPOST
      したとき、フォームのデータは特別なフォーマットで束ねられ、
      STDIN を通して、CGI プログラムに引き渡されます。
      プログラムはデータがキーボード
      もしくはファイルから来ていたかのように処理することができます。
    

      
    「特別なフォーマット」はとても単純です。フィールド名と値はイコール
      (=) で結ばれます。そして値の組はアンパサンド (&) で結ばれます。
      スペース、アンパサンド、イコールのような面倒な文字は、
      それらが動作を駄目にしないようにその文字に相当する 16 進に変換されます。
      全データ文字列は、以下のようになります:
      
    

      
    
        name=Rich%20Bowen&city=Lexington&state=KY&sidekick=Squirrel%20Monkey
      
    

      
    時々、このような文字列が URL
      に付加されるのを見るでしょう。その場合、サーバは
      QUERY_STRING という環境変数にその文字列を入れます。それは
      GET リクエストと呼ばれます。
      HTML フォームでは、データを渡すために GET と
      POST のどちらを使用するかを、FORM タグの
      METHOD 属性の設定で指定します。
    

      
    CGI プログラムは、その文字列を役に立つ情報に分割する責任があります。
      幸いにも、そのデータ処理を助けるライブラリやモジュールが存在します。
      これらは、CGI プログラムの他の面でも同様に役に立ちます。
    
    
  
    top
    

    

    CGI モジュール/ライブラリ
    
    

    
    CGI プログラムを書くとき、面倒な仕事の大部分をしてくれる
    コードライブラリまたはモジュールを使うことを検討すべきです。
    これはエラーを減らし、早い開発につながります。
    

    
    Perl で CGI プログラムを書いているなら、モジュールは CPAN で提供されています。
    この目的のための最も普及しているモジュールは CGI.pm です。
    CGI::Lite も検討しましょう。これは、ほとんどのプログラム
    において必要とするすべての機能の最小セットの実装です。
    

    
    C で CGI プログラムを書いているなら、いろいろな
    オプションがあります。これらの内の一つは http://www.boutell.com/cgic/
    で提供されている CGIC ライブラリです。
    
  
    top
    

    

    更なる情報
    
    

    
    CGI に関する情報はウェブで数多く提供されています。CGI
    の問題については Usenet の comp.infosystems.www.authoring.cgi で、
    他のユーザと論議することができます。HTML Writers Guide の
    -servers メーリングリストは、あなたの質問に回答してくれる偉大なリソースです。
    http://www.hwg.org/lists/hwg-servers/
    で更に多くを探し出すことができます。
    

    
    そしてもちろん、おそらく CGI
    プログラムの動作に関する詳細の全てが記述されている
    CGI の仕様を読むべきです。オリジナルバージョンを
    NCSA
    で、アップデートされたドラフトを
    Common Gateway Interface RFC
    プロジェクトで参照することができます。
    

    
    CGI の問題について、加わっているメーリングリストまたはニュース
    グループに質問を送るとき、起こったもの、起こってほしいこと、
    実際に起こったことがどう違うか、使用しているサーバ、
    CGI プログラムを記述している言語に関する十分な情報と、
    可能であれば問題のコードを提供するようにしてください。
    そうすることで、問題がより間単に見つかるようになります。
    

    
    Apache のソースコードにおいて問題を発見したことを確信していない限り、
    CGI の問題に関する質問を Apache
    バグデータベースに送るべきでない
    ことに注目してください。

    CGI による動的コンテンツ
    
      
    
        
    CGI (Common Gateway Interface) はウェブサーバが外部のコンテンツ
        生成プログラムとどのように相互動作をするかを定義します。
        その外部プログラムは通常 CGI プログラムや CGI スクリプトと呼ばれます。
        CGI はウェブサイトに動的なコンテンツを追加するための、
        単純な方法です。この文書は Apache ウェブサーバに
        CGI を設定し、CGI プログラムを書き始めるためのイントロダクションです。

    .htaccess ファイル
    
      
    
        
    .htaccess ファイルはディレクトリ毎に設定を変更するための
        方法を提供します。設定ディレクティブが書かれたファイルが、あるドキュメント
        ディレクトリに置かれると、ディレクティブはそのディレクトリと
        すべてのサブディレクトリに適用されます。

    Server Side Includes イントロダクション
    
      
    
        
    SSI (Server Side Includes) は HTML ページ中に書かれるディレクティブで、
        ページが送られる時にサーバにより評価されます。これにより、ページ全体を
        CGI プログラムで生成したり、他の動的な技術を使うことなく、既存の HTML
        ページに動的に生成された内容を付加することができます。

    ユーザ毎のウェブディレクトリ
    
      
    
        
    複数ユーザの存在するシステムでは、それぞれのユーザは UserDir ディレクティブを使うことによって
        ホームディレクトリ上にウェブサイトを作成することができます。
        URL http://example.com/~username/ を訪れた人は
        ユーザ "username" のホームディレクトリの、UserDir ディレクティブで指定された
       サブディレクトリからコンテンツを得ることになります。

    El protocolo HTTP/2
    
    

    
    HTTP/2 es la evolución del protocolo de la capa de aplicación con más
    éxito, HTTP. Se centra en hacer un uso más eficiente de los recursos de red. 
    No cambia la característica fundamental de HTTP, la semántica. Todavía hay 
    olicitudes, respuestas, cabeceras y todo los elementos típicos de HTTP/1. Así 
    que, si ya conoce HTTP/1, también conoce el 95% de HTTP/2.
    
    
    
    Se ha escrito mucho sobre HTTP/2 y de cómo funciona. La norma más
    estándar es, por supuesto, su 
    RFC 7540 
    ( también disponible en un
    formato más legible, YMMV). Así que, ahí encontrará toda la especificación 
    del protocolo.
    

    
    Pero, como con todos los RFC, no es ideal como primera lectura. Es mejor
    entender primero qué se quiere hacer y después leer el RFC sobre 
    cómo hacerlo. Un documento mucho mejor con el que empezar es
    http2 explicado
    por Daniel Stenberg, el autor de curl. 
    ¡También está disponible cada vez en un mayor número lenguajes!
    
    
    
    Si le parece demasiado largo, o no lo ha leido, hay algunos términos
    y elementos a tener en cuenta cuando lea este documento:
    
    
      
        
    • HTTP/2 es un protocolo binario, al contrario que 
        HTTP 1.1 que es texto plano. La intención para HTTP 1.1 es que sea 
        legible (por ejemplo capturando el tráfico de red) mientras que para 
        HTTP/2 no. Más información en el FAQ oficial 
        ¿Por qué es 
            binario HTTP/2?
      • 

        
    • h2 es HTTP/2 sobre TLS (negociación de protocolo a 
        través de ALPN).
      • 

        
    • h2c es HTTP/2 sobre TCP.
      • 

        
    • Un frame es la unidad más pequeña de comunicación 
        dentro de una conexión HTTP/2, que consiste en una cabecera y una secuencia 
        de octetos de longitud variable estructurada de acuerdo con el tipo de 
        frame. Más información en la documentación oficial 
        Sección de 
            Capa de Frame.
      • 

        
    • Un stream es un flujo bidireccional de frames dentro 
        de una conexión HTTP/2. El concepto correspondiente en HTTP 1.1 es un 
        intercambio de mensajes de solicitud/respuesta. Más información en la 
        documentación oficial 
        Sección Capa 
            de Stream.
      • 

        
    • 
            HTTP/2 es capaz de llevar múltiples streams de datos
            sobre la misma conexión TCP, evitando la clásica solicitud lenta 
            "head-of-line blocking" de HTTP 1.1 y evitando generar múltiples conexiones
            TCP para cada solicitud/respuesta (KeepAlive parcheó el problema en 
            HTTP 1.1 pero no lo resolvió completamente).
      
      •

    HTTP/2 en Apache httpd
    
    

    
    
        El protocolo HTTP/2 se implementa con su propio módulo httpd, llamado 
        acertadamente mod_http2. Incluye el set completo de 
        características descritas por el RFC 7540 y soporta HTTP/2 sobre texto 
        plano (http:), así como conexiones seguras (https:). La variante de texto
        plano se llama 'h2c', la segura 'h2'. Para 
        h2c permite el modo direct
        y el Upgrade: a través de una solicitud inicial HTTP/1.
    
    
    
    
    
        Una característica de HTTP/2 que ofrece capacidades nuevas para 
        desarrolladores de web es Server Push. Vea esa sección
         para saber como su aplicación web puede hacer uso de ella.
     
    
  
    top
    

    

    Compilar httpd con soporte HTTP/2
    
    

    
    
        mod_http2 usa la librería 
        nghttp2como su implementación base. Para compilar 
        mod_http2 necesita al menos la versión 1.2.1 de 
        libnghttp2 instalada en su sistema.
    
    

    
    
        Cuando usted ejecuta ./configure en el código fuente de 
        Apache HTTPD, necesita indicarle '--enable-http2' como una 
        opción adicional para activar la compilación de este módulo. Si su 
        libnghttp2 está ubicado en una ruta no habitual (cualquiera que 
        sea en su sistema operativo), puede indicar su ubicación con 
        '--with-nghttp2=<path>' para ./configure.
    
    

    
    Aunque puede que eso sirva para la mayoría, habrá quien prefiera un nghttp2 compilado estáticamente para este módulo. Para ellos existe la opción --enable-nghttp2-staticlib-deps. Funciona de manera muy similar a como uno debe enlazar openssl estáticamente para mod_ssl.
    

    
    Hablando de SSL, necesita estar al tanto de que la mayoría de los navegadores hablan HTTP/2 solo con URLs https:. Así que necesita un servidor con soporte SSL. Pero no solo eso, necesitará una librería SSL que de soporte a la extensión ALPN. Si usa OpenSSL, necesita al menos la versión 1.0.2.
    
  
    top
    

    

    Configuración básica
    
    

    
    Cuando tiene un httpd compilado con mod_http2 necesita una configuración básica para activarlo. Lo primero, como con cualquier otro módulo de Apache, es que necesita cargarlo:
    
    
    
    LoadModule http2_module modules/mod_http2.so
    

    
    
    La segunda directiva que necesita añadir a la configuración de su servidor es:
    

    
    Protocols h2 http/1.1
    

    
    
    Esto permite h2, la variante segura, para ser el protocolo preferido de las conexiones en su servidor. Cuando quiera habilitar todas las variantes de HTTP/2, entonces simplemente configure:
    

    
    Protocols h2 h2c http/1.1
    


    
    Dependiendo de dónde pone esta directiva, afecta a todas las conexiones o solo a las de ciertos host virtuales. La puede anidar, como en:
    

    
    Protocols http/1.1
<VirtualHost ...>
    ServerName test.example.org
    Protocols h2 http/1.1
</VirtualHost>
    


    
    Esto solo permite HTTP/1, excepto conexiones SSL hacia test.example.org que ofrecen HTTP/2.
    

    
    Escoger un SSLCipherSuite seguro
    
     
    Es necesario configurar SSLCipherSuite con una suite segura de cifrado TLS. La versión actual de mod_http2 no fuerza ningún cifrado pero la mayoría de los clientes si lo hacen. Encaminar un navegador hacia un servidor con h2 activado con una suite inapropiada de cifrados forzará al navegador a rehusar e intentar conectar por HTTP 1.1. Esto es un error común cuando se configura httpd con HTTP/2 por primera vez, ¡así que por favor tenga en cuenta que debe evitar largas sesiones de depuración! Si quiere estar seguro de la suite de cifrados que escoja, por favor evite los listados en la Lista Negra de TLS para HTTP/2.
    
    
    

    
    El orden de los protocolos mencionados también es relevante. Por defecto, el primero es el protocolo preferido. Cuando un cliente ofrece múltiples opciones, la que esté más a la izquierda será la escogida. En
    
    
    Protocols http/1.1 h2
    

    
    
    el protocolo preferido es HTTP/1 y siempre será seleccionado a menos que el cliente sólo soporte h2. Puesto que queremos hablar HTTP/2 con clientes que lo soporten, el orden correcto es:
    
    
    
    Protocols h2 h2c http/1.1
    


    
    Hay algo más respecto al orden: el cliente también tiene sus propias preferencias. Si quiere, puede configurar su servidor para seleccionar el protocolo preferido por el cliente:
    

    
    ProtocolsHonorOrder Off
    


    
    Hace que el orden en que usted escribió los Protocols sea irrelevante y sólo el orden de preferencia del cliente será decisorio.
    

    
    Una última cosa: cuando usted configura los protocolos no se comprueba si son correctos o están bien escritos. Puede mencionar protocolos que no existen, así que no hay necesidad de proteger Protocols con ningún <IfModule> de comprobación.

    Configuración MPM
    
    
    
    
    HTTP/2 está soportado en todos los módulos de multi-proceso que se ofrecen con httpd. Aun así, si usa el mpm prefork, habrá  restricciones severas.
    

    
    En prefork, mod_http2 solo procesará una solicitud cada vez por conexión. Pero los clientes, como los navegadores, enviarán muchas solicitudes al mismo tiempo. Si una de ellas tarda mucho en procesarse (o hace un sondeo que dura más de la cuenta), las otras solicitudes se quedarán atascadas.
    

    
    mod_http2 no evitará este límite por defecto. El motivo es que prefork hoy en día solo se escoge si ejecuta motores de proceso que no están preparados para multi-hilo, p.ej. fallará con más de una solicitud.
    

    
    Si su configuración lo soporta, hoy en día event es el mejor mpm que puede usar.
    
    
    
    Si realmente está obligado a usar prefork y quiere multiples solicitudes, puede configurar la directiva H2MinWorkers para hacerlo posible. Sin embargo, si esto falla, es bajo su cuenta y riesgo.

    Clientes
    
    
    
    
    Casi todos los navegadores modernos dan soporte a HTTP/2, pero solo en conexiones SSL: Firefox (v43), Chrome (v45), Safari (since v9), iOS Safari (v9), Opera (v35), Chrome para Android (v49) e Internet Explorer (v11 en Windows10) (Fuente).
    

    
    Otros clientes, así cómo otros servidores, están listados en la 
    wiki de Implementaciones, entre ellos, implementaciones para c, c++, common lisp, dart, erlang, haskell, java, nodejs, php, python, perl, ruby, rust, scala y swift.
    

    
    Muchos de las implementaciones de clientes que no son navegadores soportan HTTP/2 sobre texto plano, h2c. La más versátil es curl.
    
  
    top
    

    

    Herramientas útiles para depurar HTTP/2
    
    

    
    La primera herramienta a mencionar es por supuesto curl. Por favor asegúrese de que su versión soporta HTTP/2 comprobando sus Características:
    
    
        $ curl -V
    curl 7.45.0 (x86_64-apple-darwin15.0.0) libcurl/7.45.0 OpenSSL/1.0.2d zlib/1.2.8 nghttp2/1.3.4
    Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 [...] 
    Features: IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP HTTP2
    
    

    
    Notas sobre Mac OS homebrew
    
    brew install curl --with-openssl --with-nghttp2 
    
    
    
    Y para una inspección en gran profundidad wireshark.
    
    
    El paquete nghttp2 también incluye clientes, tales como:
    
    
      
        
    • nghttp
         - util para visualizar la frames de HTTP/2 y tener una mejor idea de como funciona el protocolo.
      • 
        
    • h2load - útil para hacer un stress-test de su servidor.
      • 
    
    

    
    Chrome ofrece logs detallados de HTTP/2 en sus conexiones a través de la página especial de net-internals. También hay una extensión interesante para Chrome y Firefox con la que visualizar cuando su navegador usa HTTP/2.
    
  
    top
    

    

    Server Push
    
    
    
    
    El protocolo HTTP/2 permite al servidor hacer PUSH de respuestas a un cliente que nunca las solicitó. El tono de la conversación es: "Aquí tiene una solicitud que nunca envió y la respuesta llegará pronto..."
    

    
    Pero hay restricciones: el cliente puede deshabilitar esta característica y el servidor entonces solo podrá hacer PUSH en una solicitud que hizo previamente del cliente.
    

    
    La intención es permitir al servidor enviar recursos que el cliente seguramente vaya a necesitar, p. ej. un recurso css o javascript que pertenece a una página html que el cliente solicitó, un grupo de imágenes a las que se hace referencia en un css, etc.
    

    
    La ventaja para el cliente es que ahorra tiempo para solicitudes que pueden tardar desde unos pocos milisegundos a medio segundo, dependiendo de la distancia entre el cliente y el servidor. La desventaja es que el cliente puede recibir cosas que ya tiene en su cache. Por supuesto que HTTP/2 soporta cancelación previa de tales solicitudes, pero aun así se malgastan recursos.
    

    
    Resumiendo: no hay una estrategia mejor sobre cómo usar esta característica de HTTP/2 y todo el mundo está experimentando con ella. Así que, ¿cómo experimenta usted con ella en Apache httpd?
    

    
    mod_http2 busca e inspecciona las cabeceras de respuesta 
    Link con cierto formato:
    

    
    Link </xxx.css>;rel=preload, </xxx.js>; rel=preload
    


    
    
        Si la conexión soporta PUSH, estos dos recursos se enviarán al cliente. 
        Como desarrollador web, puede configurar estas cabeceras o bien 
        directamente en la respuesta de su aplicación o configurar su servidor con:
    
    

    
    <Location /xxx.html>
    Header add Link "</xxx.css>;rel=preload"
    Header add Link "</xxx.js>;rel=preload"
</Location>
    


    
    Si quiere usar enlaces con preload sin activar un PUSH, puede
    usar el parámetro nopush, como en:
    

    
    Link </xxx.css>;rel=preload;nopush
    


    
    o puede desactivar PUSH para su servidor por completo con la directiva 
    

    
    H2Push Off
    


    
    Y hay más:
    

    
    
        El módulo mantiene un registro de lo que se ha enviado con PUSH para cada
        conexión (hashes de URLs, básicamente) y no hará PUSH del mismo recurso dos
        veces. Cuando la conexión se cierra, la información es descartada.
    
    

    
    
        Hay gente pensando cómo un cliente puede decirle al servidor lo que ya
        tiene, para evitar los PUSH de esos elementos, pero eso algo muy
        experimental ahora mismo.
    
    

    
    Otro borrador experimental que ha sido implementado en 
    mod_http2 es el  Campo de Cabecera
    Accept-Push-Policy en la que un cliente puede, para cada solicitud, definir 
    qué tipo de PUSH acepta.
    

    
    
        Puede que PUSH no siempre lance la peticion/respuesta/funcionamiento que
        uno espera. Hay varios estudios sobre este tema en internet, que explican
        el beneficio y las debilidades de como diferentes funcionalidades del
        cliente y de la red influyen en el resultado.
        Por Ejemplo, que un servidor haga "PUSH" de recursos, no significa que el 
        navegador vaya a usar dichos datos.
    
    
    
    
        Lo más importante que influye en la respuesta que se envía, es la solicitud
        que se simuló. La url de solicitud de un PUSH es dada por la aplicación,
        pero ¿de donde vienen las cabeceras de la petición? por ejemplo si el PUSH
        pide una cabecera accept-language y si es así, ¿con qué valor?
    
    
    
    Httpd mirará la petición original (la que originó el PUSH) y copiará las
        siguientes cabeceras a las peticiones PUSH:
        user-agent, accept, accept-encoding,
        accept-language, cache-control.
    
    
    
    
        Todas las otras cabeceras son ignorados. Las cookies tampoco serán copiadas.
        Impulsar los recursos que requieren una cookie para estar presente no
        funcionará. Esto puede ser una cuestión de debate. Pero a menos que esto se
        discuta más claramente con el navegador, evitemos el exceso de precaución y
        no expongamos las cookies donde podrían o no ser visibles.
    
    


    top
    

    

    "Early Hints"
    
    

    
    Una alternativa de "Pushear" recursos es mandar una cabecera 
        Link al cliente antes que la respuesta esté lista. Esto usa
        una caracteristica de HTTP que se llama  "Early Hints" y está descrita en
        la RFC 8297.
    
    
    Para poder usar esto, necesita habilitarlo explicitamente en el servidor 
    via
    
    
    
    H2EarlyHints on
    

    
    
    (No está habilitado por defecto ya q ue algunos navegadores más antiguos 
        se caen con dichas  respuestas.)
    
    

    
    si esta funcionalidad esta activada, puede usar la directiva 
        H2PushResource para que lance 
        "Early hints" y recursos mediante push:
    
    
    
    <Location /xxx.html>
    H2PushResource /xxx.css
    H2PushResource /xxx.js
</Location>
    

    
    
        Esto lanzará una respuesta "103 Early Hints" a un cliente 
        tan pronto como el servidor comience a procesar la solicitud. 
        Esto puede ser mucho antes que en el momento en que se determinaron los 
        primeros encabezados de respuesta, dependiendo de su aplicación web.
    
    

    
    
        Si la directiva H2Push está 
        habilitada, esto comenzará el PUSH justo después de la respuesta 103.
        Sin embargo, si la directiva H2Push está dehabilitada, la respuesta 103 se le enviará al cliente.

    .htaccess ファイルはディレクトリ毎に設定を変更する方法を
提供します。

    .htaccess ファイルとは何か/その使い方
    


    
    .htaccess ファイル (「分散設定ファイル」) は
    ディレクトリ毎に設定を変更する方法を提供します。ディレクティブの
    書かれたファイルをディレクトリに置くことで、そのディレクトリとその
    サブディレクトリすべてにディレクティブを適用させることができます。
    

    
    注:
    
      
    .htaccess ファイルを別の名前にしたい場合は、
      AccessFileName ディレクティブを
      使って変更することができます。例えば、そのファイルを .config 
      という名前にしたい場合は、以下の設定をサーバ設定ファイルに入れることが
      できます:
    

      
    
        AccessFileName .config
      
    
    
    

    
    一般に、.htaccess ファイルの構文は
    主設定ファイル
    と同じです。これらのファイルに書くことのできるディレクティブは AllowOverride ディレクティブにより決まります。
    このディレクティブは、.htaccess ファイルに
    書かれたディレクティブの中で、、
    どのディレクティブが適用されるかをカテゴリー単位で指定します。
    .htaccess に書くことのできるディレクティブであれば、
    説明文書には「上書き」という項目があり、.htaccess に書くことができるように
    なるための AllowOverride の値が指定されています。
    

    
    例えば、AddDefaultCharset ディレクティブの説明を
    見ると、.htaccess ファイルでの使用が許可されていることが
    わかります。 (ディレクティブの概要の所にある「コンテキスト」と書かれている
    行を見てください。) 上書きと書かれている行には
    FileInfo とあります。ですから、.htaccess 中の
    このディレクティブが有効になるためには、少なくとも
    AllowOverride FileInfo が設定されている必要があります。
    

    
    例:
    
        
    
          コンテキスト:
          サーバ設定ファイル,バーチャルホスト,ディレクトリ,.htaccess
        
    

        
    
          上書き:
          FileInfo
        
    
      
    

    
    あるディレクティブを .htaccess ファイルに書くことができるか
    どうかわからないときは、そのディレクティブの説明を探して、".htaccess"
    のための「コンテキスト」の行を調べてください。
    
    
    top
    

    

    いつ .htaccess ファイルを使う(使わない)か。
    

    
    一般的に、サーバの主設定ファイルにアクセスできない場合を除いて、
    .htaccess ファイルの使用は極力避けてください。
    世の中には、例えば、ユーザ認証は常に .htaccess ファイルで
    行なわなければならない、という誤解が広まっていますが、まったくそんなことは
    ありません。ユーザ認証の設定はサーバ主設定ファイルに書くことができ、
    実際、その方がより良い設定方法です。
    

    
    .htaccess ファイルはコンテンツ提供者がディレクトリ毎の
    設定を行ないたいけれど、サーバシステムの root アクセス権限を持っていない
    という場合にのみ使うべきものです。サーバ管理者が頻繁に設定変更を行ないたくは
    ない、というときには個々のユーザが .htaccess ファイルを使って
    自分で設定の変更を行なうことを許可した方が良いときもあるでしょう。
    これは特に、ISP が複数のユーザのサイトを一つのマシンでホストしていて、
    各ユーザが設定の変更をできるようにしたいようなときにあてはまります。
    

    
    しかし、普通は可能であれば .htaccess ファイルの使用は
    避けてください。.htaccess ファイルに書こうと考えるような
    すべての設定は、サーバの主設定ファイルの <Directory> セクションで同じように行なうことが
    できます。
    

    
    .htaccess ファイルの使用を避ける理由は主に二つあります。
    

    
    一つ目はサーバの性能の問題です。AllowOverride ディレクティブが
    .htaccess ファイルの設定を許可している場合は、Apache は
    各ディレクトリで .htaccess ファイルを探します。
    ですから、.htaccess ファイルを許可すると、実際に使用しているか
    どうかに関わらず、性能の低下を招くことになります! また、.htaccess
    ファイルは文書がリクエストされる度に読み込まれます。
    

    
    さらに、Apache は適用すべきディレクティブを集めるために、すべての
    上位のディレクトリの .htaccess ファイルを探す必要があることにも
    注意してください。(ディレクティブが適用される方法を
    参照してください。)ですから、/www/htdocs/example にある
    ファイルがリクエストされたときは、Apache は以下のファイルを調べます。
    

    
    
      /.htaccess
    
      /www/.htaccess
    
      /www/htdocs/.htaccess
    
      /www/htdocs/example/.htaccess
    
    

    
    ですから、そのディレクトリのそれぞれのファイルへのアクセスに対して、
    上の例のファイルがまったく存在しないときでも、追加のファイルシステムの
    アクセスが行なわれることになります。(これは、.htaccess が
    / に対して有効になっているときの場合で、普通はそうなって
    いないことに注意してください。)
    

    
    二つ目はセキュリティです。ユーザにサーバの設定を変更することを
    許可することになりますので、あなた自身が管理できない変更をされる
    恐れがあります。ユーザにこの特権を与えるのが良いのかどうか、十分
    検討してください。また、ユーザに与える権限が必要なものよりも少なすぎると、
    余分な技術サポート報告を受け取るようになる可能性が高いことにも
    注意してください。確実に、ユーザにどの程度の権限を与えたか明確に告げるように
    してください。AllowOverride に
    何を設定したかということと、関連する文書を示すことで、
    後々の混乱をぐっと減らすことが
    できます。
    

    
    ところで、ディレクティブの書かれた .htaccess を
    /www/htdocs/example に置くことと、同じディレクティブを
    主サーバ設定の Directory セクション
    <Directory /www/htdocs/example> に書くことは
    完全に等価です:
    

    
    /www/htdocs/example の .htaccess ファイル:
    

    
    /www/htdocs/example の .htaccess ファイルの
    内容
    
        AddType text/example .exm
    
    

    
    httpd.conf のセクション
    file
    
      <Directory /www/htdocs/example>
    
      
        AddType text/example .exm
    
          
      </Directory>
    
    

    
    しかし、この設定はサーバ設定ファイルに書いた方がパフォーマンスの
    低下が少なくなります。ファイルがリクエストされる度に
    読み込まれる代わりに、Apache の起動時に 1 回だけ読み込めば
    よくなるからです。
    

    
    AllowOverride ディレクティブの
    値を none に設定することで .htaccess ファイル
    の使用を完全に無効にすることができます。
    

    
    
      AllowOverride None
    
    

    top
    

    

    ディレクティブの適用のされ方
    

    
    .htaccess ファイルの設定ディレクティブは .htaccess
    ファイルの存在するディレクトリと、そのサブディレクトリすべてに適用されます。
    しかし、上の階層のディレクトリにも .htaccess ファイルが
    存在するかもしれないことを覚えておくことは大切です。ディレクティブは現れる
    順番に適用されます。ですから、あるディレクトリの .htaccess は
    ディレクトリツリーのより上の階層の .htaccess ファイルの
    設定を上書きするかもしれません。そして、その .htaccess も
    より上の階層で書かれたディレクティブを上書きしたり、主サーバ設定ファイル
    そのものの設定を上書きしたりしているかもしれません。
    

    
    例:
    

    
    ディレクトリ /www/htdocs/example1 に以下の内容の
    .htaccess ファイルがあります:
    

    
    
       Options +ExecCGI
    
    

    
    (注: .htaccess
    ファイルで "Options" ディレクティブが有効になるためには、
    "AllowOverride Options" を有効にする必要があります。)
    

    
    ディレクトリ /www/htdocs/example1/example2 には
    以下のような .htaccess ファイルがあります:
    

    
    
       Options Includes
    
    

    
    二つめの .htaccess により、ディレクトリ
    /www/htdocs/example1/example2 では CGI の実行は
    許可されません。これは、Options Includes のみが
    効力を持ち、それがすべての以前の設定を上書きするからです。
    

    
    メイン設定ファイルに対する
    .htaccess のマージ
    

    
    As discussed in the documentation on Configuration Sections,
    .htaccess files can override the <Directory> sections for
    the corresponding directory, but will be overriden by other types
    of configuration sections from the main configuration files.  This
    fact can be used to enforce certain configurations, even in the
    presence of a liberal AllowOverride setting.  For example, to
    prevent script execution while allowing anything else to be set in
    .htaccess you can use:
    
    
    セクションの設定
    に記載されているように、.htaccess ファイルを使って
    <Directory>
    セクションの設定をディレクトリ毎に上書きできますが、
    メイン設定ファイル中にある、他の種類の設定セクションによって
    さらに上書きされることもあります。
    この特徴を使って、
    AllowOverride
    で自由度の高い設定があったとしても、ある特定の設定が確実に
    反映されるようにできます。例えば、CGI スクリプトの実行は
    不許可に、かつ、.htaccess でその他の項目は
    設定できるように、という場合は次のようにできます :
    
    
    
    
<Directory />
    

Allowoverride All
    
    
</Directory>
    

    
<Location />
    

Options +IncludesNoExec -ExecCGI
    
    
</Location>

    認証の例
    

    
    もし認証の方法を知るためにこの部分に直接来たのであれば、次のことを
    知っておくことが重要です。よくある誤解に、パスワード認証を行なうためには
    .htaccess ファイルを使う必要がある、というものがあります。
    これは正しくありません。主サーバ設定ファイルの <Directory> セクションに
    認証用のディレクティブを書く方が推奨される方法で、.htaccess
    ファイルは主サーバ設定ファイルを変更できないときにのみ使用すべきです。
    いつ .htaccess ファイルを使うべきで、いつ使うべきではないかに
    ついては 上を参照してください。
    

    
    以上のことをふまえた上で、もし .htaccess の使用が
    まだ必要だと思う場合は、次のようなものが望みのことをしてくれるかも
    しれません。
    

    
    .htaccess ファイルの内容:
    

    
    
      AuthType Basic
    
      AuthName "Password Required"
    
      AuthUserFile /www/passwords/password.file
    
      AuthGroupFile /www/passwords/group.file
    
      Require Group admins
    
    

    
    これらのディレクティブが有効になるためには、
    AllowOverride AuthConfig が有効でなくてはならないことに
    注意してください。
    

    
    認証と承認については 認証チュートリアルを
    参照してください。
    

    top
    

    

    SSI の例
    

    
    もう一つの .htaccess ファイルのよくある利用法は
    特定のディレクトリで SSI を有効にすることです。これは、望みのディレクトリの
    .htaccess ファイルに以下の設定ディレクティブを書くことで

    CGI の例
    

    
    最後に、特定のディレクトリで CGI プログラムの実行を許可したいことが
    あるでしょう。これは以下の設定で行なうことができます:
    

    
    
       Options +ExecCGI
    
       AddHandler cgi-script cgi pl
    
    

    
    もしくは、あるディレクトリのすべてのファイルが CGI プログラムと
    みなされるようにしたいなら、以下の設定で実現することができます:
    

    
    
       Options +ExecCGI
    
       SetHandler cgi-script
    
    

    
    これらのディレクティブが有効になるためには、
    AllowOverride Options と AllowOverride
    FileInfo が有効である必要があることに注意してください。
    

    
    CGI プログラムと設定のよりまとまった説明は CGI チュートリアルを参照してください。

    問題解決
    

    
    設定ディレクティブを .htaccess ファイルに書いたけれども、
    期待した効果が得られないときには、いくつかの原因が考えられます。
    

    
    一番よくあることは、設定ディレクティブが考慮されるようには
    AllowOverride が設定されていない
    というものです。該当のファイルのスコープに AllowOverride None
    が設定されていないことを確認してください。これを調べるための良い方法は、
    .htaccess ファイルにごみを書いて、リロードすることです。
    サーバのエラーが生成されないときは、ほぼ確実に AllowOverride
    None が設定されている状態になっています。
    

    
    そうではなく、文書をアクセスしようとしたときにエラーが発生している
    ときは、Apache のエラーログを調べてください。.htaccess ファイルで
    使用されたディレクティブが許可されていない、ということを知らせている
    可能性が高いです。または、構文の間違いがあることを述べているかもしれません。
    その場合にはまずそれを修正する必要があります。

    Sur les systèmes multi-utilisateurs, on peut permettre à chaque
utilisateur d'avoir un site web dans son répertoire home à l'aide de la
directive UserDir. Les
visiteurs de l'URL http://example.com/~nom_utilisateur/
recevront un contenu situé dans le répertoire home de l'utilisateur
"nom_utilisateur", et dans le sous-répertoire spécifié par
la directive UserDir.
    

    Notez que par défaut, l'accès à ces répertoires n'est
pas permis. Vous pouvez en permettre l'accès à l'aide
de la directive UserDir en
décommentant la ligne :
    
    
    #Include conf/extra/httpd-userdir.conf
    

    
    dans le fichier de configuration par défaut
    conf/httpd.conf, et en adaptant le
    fichier httpd-userdir.conf selon vos besoins, ou en
    incluant les directives appropriées dans une section
    <Directory> du fichier de
    configuration principal.

    top
    

    

    Définition du chemin des fichiers avec UserDir
    
    

    
    La directive UserDir
    permet de spécifier un répertoire à partir duquel le contenu de
    l'utilisateur pourra être chargé. Elle peut revêtir plusieurs
    formes.
    

    
    Si le chemin spécifié ne commence pas par un slash, il sera
    interprété comme chemin relatif au répertoire home de l'utilisateur
    considéré. Par exemple, avec cette configuration :
    

    
    UserDir public_html
    


    
    l'URL http://example.com/~rbowen/fichier.html
    correspondra au chemin fichier
    /home/rbowen/public_html/fichier.html
    

    
    Si le chemin spécifié commence par un slash, le chemin du fichier
    sera construit en utilisant ce chemin, suivi du nom de l'utilisateur
    considéré. Par exemple, avec cette configuration :
    

    
    UserDir /var/html
    


    
    l'URL http://example.com/~rbowen/fichier.html
    correspondra au chemin fichier
    /var/html/rbowen/fichier.html
    

    
    Si le chemin spécifié contient un astérisque (*), ce dernier sera
    remplacé par le nom de l'utilisateur dans le chemin du fichier
    correspondant. Par exemple, avec cette configuration :
    

    
    UserDir /var/www/*/docs
    


    
    l'URL http://example.com/~rbowen/fichier.html
    correspondra au chemin fichier
    /var/www/rbowen/docs/fichier.html
    

    
    On peut aussi définir plusieurs répertoires ou chemins de
    répertoires.
    

    
    UserDir public_html /var/html
    


    
    Avec l'URL http://example.com/~rbowen/fichier.html,
    Apache va rechercher ~rbowen. S'il ne le trouve pas,
    Apache va rechercher rbowen dans
    /var/html. S'il le trouve, l'URL ci-dessus correspondra
    au chemin fichier /var/html/rbowen/file.html
    

  
    top
    

    

    Redirection vers des URLs externes
    
    
    
    On peut utiliser la directive UserDir pour rediriger les requêtes
    relatives aux répertoires utilisateurs vers des URLs externes.
    

    
    UserDir http://example.org/users/*/
    


    
    L'exemple ci-dessus va rediriger une requête pour
    http://example.com/~bob/abc.html vers
    http://exemple.org/users/bob/abc.html.
    
  
    top
    

    

    Définition de la liste des utilisateurs autorisés à utiliser
    cette fonctionnalité
    
    

    
    En suivant la syntaxe décrite dans la documentation de UserDir,
    vous pouvez définir quels utilisateurs sont autorisés à utiliser
    cette fonctionnalité :
    

    
    UserDir disabled root jro fish
    


    
    La configuration ci-dessus va autoriser l'utilisation de la
    fonctionnalité pour tous les utilisateurs, à l'exception de ceux
    listés à la suite de l'argument disabled. De même, vous
    pouvez interdire l'utilisation de la fonctionnalité à tous les
    utilisateurs sauf certains d'entre eux en utilisant une
    configuration du style :
    

    
    UserDir disabled
UserDir enabled rbowen krietz
    


    
    Vous trouverez d'autres exemples dans la documentation de
    UserDir.
    

  
    top
    

    

    Définition d'un répertoire CGI pour chaque utilisateur
    
  

   
    Afin de réserver un répertoire cgi-bin pour chaque utilisateur,
   vous pouvez utiliser une section <Directory> pour activer CGI dans un
   sous-répertoire particulier d'un répertoire home utilisateur.
    

    
    <Directory "/home/*/public_html/cgi-bin/">
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    


    
    Avec la configuration ci-dessus, et en supposant que
    UserDir est défini à public_html, un
    programme CGI exemple.cgi pourra être chargé depuis ce
    répertoire en passant par l'URL :
    

    
    
    http://example.com/~rbowen/cgi-bin/exemple.cgi
    
    

    
    top
    

    

    Permettre aux utilisateurs de modifier la
    configuration
    
    

    
    Si vous voulez que vos utilisateurs puissent modifier la
    configuration du serveur pour ce qui concerne leur espace web, ils
    devront utiliser des fichiers .htaccess pour effectuer
    ces modifications. Assurez-vous d'avoir défini la directive
    AllowOverride à une valeur
    appropriée pour les directives dont vous voulez permettre la
    modification aux utilisateurs. Voir le tutoriel .htaccess pour plus de détails sur
    la manière dont tout ceci fonctionne.

    This is the howto guide for the HTTP/2 implementation in Apache httpd. This
    feature is production-ready and you may expect interfaces and directives to
    remain consistent releases.

    The HTTP/2 protocol
    
    
    
    HTTP/2 is the evolution of the world's most successful application layer protocol, HTTP.
    It focuses on making more efficient use of network resources. It does not change the fundamentals
    of HTTP, the semantics. There are still request and responses and headers and all that. So, if
    you already know HTTP/1, you know 95% about HTTP/2 as well.
    
    
    There has been a lot written about HTTP/2 and how it works. The most normative is, of course,
    its RFC 7540 
    (also available in more readable formatting, YMMV).
    So, there you'll find the nuts and bolts.
    
    
    But, as RFC do, it's not really a good thing to read first. It's better to first understand
    what a thing wants to do and then read the RFC about how it is done. A much
    better document to start with is http2  explained
    by Daniel Stenberg, the author of curl. It is available in
    an ever growing list of languages, too!
    
    
    Too Long, Didn't read: there are some new terms and gotchas that need to be kept in mind while reading this document:
    
    
      
        
    • HTTP/2 is a binary protocol, as opposed to HTTP 1.1 that is plain text. The latter is meant to be human readable (for example sniffing network traffic) meanwhile the former is not. More info in the official FAQ question.
      • 
        
    • h2 is HTTP/2 over TLS (protocol negotiation via ALPN).
      • 
        
    • h2c is HTTP/2 over TCP.
      • 
        
    • A frame is the smallest unit of communication within an HTTP/2 connection, consisting of a header and a variable-length sequence of octets structured according to the frame type. More info in the official documentation  section.
      • 
        
    • A stream is a bidirectional flow of frames within the HTTP/2 connection. The correspondent concept in HTTP 1.1 is a request/response message exchange. More info in the official documentation  section.
      • 
        
    • HTTP/2 is able to run multiple streams of data over the same TCP connection, avoiding the classic HTTP 1.1 head of blocking slow request and avoiding to re-instantiate TCP connections for each request/response (KeepAlive patched the problem in HTTP 1.1 but did not fully solve it).
      • 
    
    
  
    top
    

    

    HTTP/2 in Apache httpd
    
    
    
    The HTTP/2 protocol is implemented by its own httpd module, aptly named
    mod_http2. It implements the complete set
    of features described by RFC 7540 and supports HTTP/2 over cleartext (http:), as
    well as secure (https:) connections. The cleartext variant is named 'h2c', 
    the secure one 'h2'. For h2c it allows the direct
    mode and the Upgrade: via an initial HTTP/1 request.
    
    
    One feature of HTTP/2 that offers new capabilities for web developers is
    Server Push. See that section on how your web application
    can make use of it.
    
  
    top
    

    

    Build httpd with HTTP/2 support
    
    
    
    mod_http2 uses the library of nghttp2
    as its implementation base. In order to build mod_http2 you need at least version 1.2.1 of
    libnghttp2 installed on your system.
    
    
    When you ./configure you Apache httpd source tree, you need to give it 
    '--enable-http2' as additional argument to trigger the build of the module.
    Should your libnghttp2 reside in an unusual place (whatever that is on your
    operating system), you may announce its location with '--with-nghttp2=<path>'
    to configure.
    
    
    While that should do the trick for most, they are people who might prefer a statically
    linked nghttp2 in this module. For those, the option --enable-nghttp2-staticlib-deps
    exists. It works quite similar to how one statically links openssl to mod_ssl.
    
    
    Speaking of SSL, you need to be aware that most browsers will speak HTTP/2 only on https:
    URLs, so you need a server with SSL support. But not only that, you will need a SSL library
    that supports the ALPN extension. If OpenSSL is the library you use, you need
    at least version 1.0.2.
    
  
    top
    

    

    Basic Configuration
    
    

    
    When you have a httpd built with mod_http2 you need some
    basic configuration for it becoming active. The first thing, as with every Apache module,
    is that you need to load it:
    
    
    LoadModule http2_module modules/mod_http2.so
    

    
    
    The second directive you need to add to your server configuration is
    
    
    Protocols h2 http/1.1
    

    
    This allows h2, the secure variant, to be the preferred protocol on your server
    connections. When you want to enable all HTTP/2 variants, you simply write:
    
    
    Protocols h2 h2c http/1.1
    

    
    Depending on where you put this directive, it affects all connections or just
    the ones to a certain virtual host. You can nest it, as in:
    
    
    Protocols http/1.1
<VirtualHost ...>
    ServerName test.example.org
    Protocols h2 http/1.1
</VirtualHost>
    


    
    This allows only HTTP/1 on connections, except SSL connections to test.example.org
    which offer HTTP/2.
    
    
    Choose a strong SSLCipherSuite
    
    
    The SSLCipherSuite needs to be configured with
    a strong TLS cipher suite. The current version of mod_http2 does not enforce any cipher but most
    clients do so. Pointing a browser to a h2 enabled server with a inappropriate
    cipher suite will force it to simply refuse and fall back to HTTP 1.1. This is a common mistake
    that is done while configuring httpd for HTTP/2 the first time, so please keep it in mind to avoid
    long debugging sessions! If you want to be sure about the cipher suite to choose please avoid
    the ones listed in the HTTP/2 TLS reject list.
    
    
    
    
    The order of protocols mentioned is also relevant. By default, the first one is the 
    most preferred protocol. When a client offers multiple choices, the one most to the 
    left is selected. In
    
    
    Protocols http/1.1 h2
    

    
    the most preferred protocol is HTTP/1 and it will always be selected unless a 
    client only supports h2. Since we want to talk HTTP/2 to clients that
    support it, the better order is
    
    
    Protocols h2 h2c http/1.1
    


    
    There is one more thing to ordering: the client has its own preferences, too. If
    you want, you can configure your server to select the protocol most preferred by
    the client:
    
    
    ProtocolsHonorOrder Off
    

    
    makes the order you wrote the Protocols irrelevant and only the client's
    ordering will decide.
    
    
    A last thing: the protocols you configure are not checked for correctness
    or spelling. You can mention protocols that do not exist, so there is no need
    to guard Protocols with any
    <IfModule> checks.
    
    
    For more advanced tips on configuration, see the 
    modules section about dimensioning and 
    how to manage multiple hosts with the same certificate.
    
  
    top
    

    

    MPM Configuration
    
    
    
    
    HTTP/2 is supported in all multi-processing modules that come with httpd. However, if
    you use the prefork mpm, there will be severe restrictions.
    
    
    In prefork, mod_http2 will only process one request at at time
    per connection. But clients, such as browsers, will send many requests at the same time.
    If one of these takes long to process (or is a long polling one), the other requests will
    stall.
    
    
    mod_http2 will not work around this limit by default. The reason is that
    prefork is today only chosen, if you run processing engines that are not
    prepared for multi-threading, e.g. will crash with more than one request.
    
    
    If your setup can handle it, configuring event mpm is nowadays
    the best one (if supported on your platform).
    
    
    If you are really stuck with prefork and want multiple requests,
    you can tweak the H2MinWorkers to make
    that possible. If it breaks, however, you own both parts.
    
  
    top
    

    

    Clients
    
    
    
    Almost all modern browsers support HTTP/2, but only over SSL connections: Firefox (v43),
    Chrome (v45), Safari (since v9), iOS Safari (v9), Opera (v35), Chrome for Android (v49)
    and Internet Explorer (v11 on Windows10) (source).
    
    
    Other clients, as well as servers, are listed 
    on the Implementations wiki,
    among them implementations for c, c++, common lisp, dart, erlang, haskell, java, nodejs,  php, 
    python, perl, ruby, rust, scala and swift.
    
    
    Several of the non-browser client implementations support HTTP/2 over cleartext, h2c. The
    most versatile being curl.
    
  
    top
    

    

    Useful tools to debug HTTP/2
    
    
    
    The first tool to mention is of course curl. Please make sure that
    your version supports HTTP/2 checking its Features:
    
    
        $ curl -V
    curl 7.45.0 (x86_64-apple-darwin15.0.0) libcurl/7.45.0 OpenSSL/1.0.2d zlib/1.2.8 nghttp2/1.3.4
    Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 [...] 
    Features: IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP HTTP2
    
    

    
    Mac OS homebrew notes
    
    brew install curl --with-openssl --with-nghttp2 
    
    
    
    And for really deep inspection wireshark.
    
    
    The nghttp2 package also includes clients, such as:
    
    
      
        
    • nghttp - useful to visualize the HTTP/2 frames and get a better idea of the protocol.
      • 
        
    • h2load - useful to stress-test your server.
      • 
    
    
    
    Chrome offers detailed HTTP/2 logs on its connections via the 
    special net-internals page. There is also an
    interesting extension for Chrome
    and Firefox
    to visualize when your browser is using HTTP/2.
    
  
    top
    

    

    Server Push
    
    
    
    The HTTP/2 protocol allows the server to PUSH responses to a client it never
    asked for. The tone of the conversation is: "here is a request that you
    never sent and the response to it will arrive soon..."
    
    
    But there are restrictions: the client can disable this feature and the
    server may only ever PUSH on a request that came from the client.
    
    
    The intention is to allow the server to send resources to the client that
    it will most likely need: a css or javascript resource that belongs to a html
    page the client requested. A set of images that is referenced by a css, etc.
    
    
    The advantage for the client is that it saves the time to send the request which
    may range from a few milliseconds to half a second, depending on where on the 
    globe both are located. The disadvantage is that the client may get sent
    things it already has in its cache. Sure, HTTP/2 allows for the early cancellation
    of such requests, but still there are resources wasted.
    
    
    To summarize: there is no one good strategy on how to make best use of this 
    feature of HTTP/2 and everyone is still experimenting. So, how do you experiment
    with it in Apache httpd?
    
    
    mod_http2 inspect response header for Link headers
    in a certain format:
    
    
    Link </xxx.css>;rel=preload, </xxx.js>; rel=preload
    

    
    If the connection supports PUSH, these two resources will be sent to the
    client. As a web developer, you may set these headers either directly in
    your application response or you configure the server via
    
    
    <Location /xxx.html>
    Header add Link "</xxx.css>;rel=preload"
    Header add Link "</xxx.js>;rel=preload"
</Location>
    

    
    If you want to use preload links without triggering a PUSH, you
    can use the nopush parameter, as in
    
    
    Link </xxx.css>;rel=preload;nopush
    

    
    or you may disable PUSHes for your server entirely with the directive
    
    
    H2Push Off
    

    
    And there is more:
    
    
    The module will keep a diary of what has been PUSHed for each connection
    (hashes of URLs, basically) and will not PUSH the same resource twice. When
    the connection closes, this information is discarded.
    
    
    There are people thinking about how a client can tell a server what it
    already has, so PUSHes for those things can be avoided, but this is all
    highly experimental right now.
    
    
    Another experimental draft that has been implemented in mod_http2
    is the 
    Accept-Push-Policy Header Field where a client can, for each request, define
    what kind of PUSHes it accepts.
    
    
    
    PUSH might not always trigger the request/response/performance that one expects or 
    hopes for. There are various studies on this topic to be found on the web that explain
    benefits and weaknesses and how different features of client and network influence
    the outcome. For example: just because the server PUSHes a resource does not mean
    a browser will actually use the data.
    
    
    The major thing that influences the response being PUSHed is the request that was
    simulated. The request URL for a PUSH is given by the application, but where do the
    request headers come from? For example, will the PUSH request a accept-language
    header and if yes with what value?
    
    
    Apache will look at the original request (the one that triggered the PUSH) and copy the 
    following headers over to PUSH requests: user-agent, accept, 
    accept-encoding, accept-language, cache-control.
    
    
    All other headers are ignored. Cookies will also not be copied over. PUSHing resources
    that require a cookie to be present will not work. This can be a matter of debate. But 
    unless this is more clearly discussed with browser, let's err on the side of caution and
    not expose cookie where they might ordinarily not be visible.
    
  
    top
    

    

    Early Hints
    
    
    
    An alternative to PUSHing resources is to send Link headers to the
    client before the response is even ready. This uses the HTTP feature called "Early Hints" and
    is described in RFC 8297.
    
    
    In order to use this, you need to explicitly enable it on the server via
    
    
    H2EarlyHints on
    

    
    (It is not enabled by default since some older browser tripped on such responses.)
    
    
    If this feature is on, you can use the directive H2PushResource to 
    trigger early hints and resource PUSHes:
    
    
    <Location /xxx.html>
    H2PushResource /xxx.css
    H2PushResource /xxx.js
</Location>
    

    
    This will send out a "103 Early Hints" response to a client as soon
    as the server starts processing the request. This may be much early than
    the time the first response headers have been determined, depending on your web
    application.
    
    
    If H2Push is enabled, this will also start the PUSH right after the
    103 response. If H2Push is disabled however, the 103 response will be send
    nevertheless to the client.

    On systems with multiple users, each user can be permitted to have a
    web site in their home directory using the UserDir directive. Visitors
    to a URL http://example.com/~username/ will get content
    out of the home directory of the user "username", out of
    the subdirectory specified by the UserDir directive.
    

    Note that, by default, access to these directories is not
    enabled. You can enable access when using UserDir by uncommenting the line:
    
    
    #Include conf/extra/httpd-userdir.conf
    

    
    in the default config file conf/httpd.conf, and adapting the httpd-userdir.conf
    file as necessary, or by including the appropriate directives in a
    <Directory> block
    within the main config file.

    Setting the file path with UserDir
    
    

    
    The UserDir
    directive specifies a directory out of which per-user
    content is loaded. This directive may take several different forms.
    

    
    If a path is given which does not start with a leading slash, it is
    assumed to be a directory path relative to the home directory of the
    specified user. Given this configuration:
    

    
    UserDir public_html
    


    
    the URL http://example.com/~rbowen/file.html will be
    translated to the file path
    /home/rbowen/public_html/file.html
    

    
    If a path is given starting with a slash, a directory path will be
    constructed using that path, plus the username specified. Given this
    configuration:
    

    
    UserDir /var/html
    


    
    the URL http://example.com/~rbowen/file.html will be
    translated to the file path /var/html/rbowen/file.html
    

    
    If a path is provided which contains an asterisk (*), a path is used
    in which the asterisk is replaced with the username. Given this
    configuration:
    

    
    UserDir /var/www/*/docs
    


    
    the URL http://example.com/~rbowen/file.html will be
    translated to the file path
    /var/www/rbowen/docs/file.html
    

    
    Multiple directories or directory paths can also be set.
    

    
    UserDir public_html /var/html
    


    
    For the URL http://example.com/~rbowen/file.html,
    Apache will search for ~rbowen. If it isn't found,
    Apache will search for rbowen in /var/html. If
    found, the above URL will then be translated to the file path
    /var/html/rbowen/file.html
    

  
    top
    

    

    Redirecting to external URLs
    
    
    
    The UserDir directive can be
      used to redirect user directory requests to external URLs.
    

    
    UserDir http://example.org/users/*/
    


    
    The above example will redirect a request for
    http://example.com/~bob/abc.html to
    http://example.org/users/bob/abc.html.
    
  
    top
    

    

    Restricting what users are permitted to use this
    feature
    
    

    
    Using the syntax shown in the UserDir documentation, you can restrict
    what users are permitted to use this functionality:
    

    
    UserDir disabled root jro fish
    


    
    The configuration above will enable the feature for all users
    except for those listed in the disabled statement.
    You can, likewise, disable the feature for all but a few users by
    using a configuration like the following:
    

    
    UserDir disabled
UserDir enabled rbowen krietz
    


    
    See UserDir
    documentation for additional examples.
    

  
    top
    

    

    Enabling a cgi directory for each user
    
  

   
    In order to give each user their own cgi-bin directory, you can use
    a <Directory>
    directive to make a particular subdirectory of a user's home directory
    cgi-enabled.
    

    
    <Directory "/home/*/public_html/cgi-bin/">
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    


    
    Then, presuming that UserDir is set to
    public_html, a cgi program example.cgi
    could be loaded from that directory as:
    

    
    
    http://example.com/~rbowen/cgi-bin/example.cgi
    
    

    
    top
    

    

    Allowing users to alter configuration
    
    

    
    If you want to allows users to modify the server configuration in
    their web space, they will need to use .htaccess files to
    make these changes. Ensure that you have set AllowOverride to a
    value sufficient for the directives that you want to permit the users
    to modify. See the .htaccess tutorial for
    additional details on how this works.

    L'authentification est un processus qui vous permet de vérifier
    qu'une personne est bien celle qu'elle prétend être. L'autorisation
    est un processus qui permet à une personne d'aller là où elle veut
    aller, ou d'obtenir les informations qu'elle désire.
    

    
    Pour le contrôle d'accès en général, voir le How-To Contrôle d'accès.

    Modules et directives concernés
    


    Trois groupes de modules sont concernés par le processus
d'authentification et d'autorisation. Vous devrez utiliser au moins un
module de chaque groupe.
    



  
    On peut aussi ajouter mod_authn_core et
  mod_authz_core. Ces modules implémentent des
  directives générales qui opèrent au dessus de tous les modules
  d'authentification.
    

  
    Le module mod_authnz_ldap est un fournisseur
  d'authentification et d'autorisation. Le module
  mod_authz_host fournit une autorisation et un
  contrôle d'accès basés sur le nom du serveur, l'adresse IP ou
  certaines caractéristiques de la requête, mais ne fait pas partie du
  système fournisseur d'authentification. Le module
  mod_access_compat a été créé à des fins de
  compatibilité ascendante avec mod_access.
    

  
    Vous devriez aussi jeter un coup d'oeil au manuel de recettes de Contrôle d'accès, qui décrit les différentes
  méthodes de contrôle d'accès à votre serveur.

    Introduction
    
    
    Si votre site web contient des informations sensibles ou
    destinées seulement à un groupe de personnes restreint, les
    techniques exposées dans cet article vont vous aider à vous assurer
    que les personnes qui ont accès à ces pages sont bien celles
    auxquelles vous avez donné l'autorisation d'accès.
    

    
    Cet article décrit les méthodes "standards" de protection de
    parties de votre site web que la plupart d'entre vous sont appelés à
    utiliser.
    

    
    Note :
    
    
    Si vos données ont un réel besoin de sécurisation, prévoyez
    l'utilisation de mod_ssl en plus de toute méthode
    d'authentification.
    
    
    

    top
    

    

    Les prérequis
    
    
    Les directives décrites dans cet article devront être insérées
    soit au niveau de la configuration de votre serveur principal (en
    général dans une section <Directory>), soit au niveau de la
    configuration des répertoires (fichiers .htaccess)
    

    
    Si vous envisagez l'utilisation de fichiers
    .htaccess, la configuration de votre serveur devra
    permettre l'ajout de directives d'authentification dans ces
    fichiers. Pour ce faire, on utilise la directive AllowOverride, qui spécifie quelles
    directives pourront éventuellement contenir les fichiers de
    configuration de niveau répertoire.
    

    
    Comme il est ici question d'authentification, vous aurez besoin
    d'une directive AllowOverride
    du style :
    

    
    AllowOverride AuthConfig
    


    
    Si vous avez l'intention d'ajouter les directives directement
    dans le fichier de configuration principal, vous devrez bien entendu
    posséder les droits en écriture sur ce fichier.
    

    
    Vous devrez aussi connaître un tant soit peu la structure des
    répertoires de votre serveur, ne serait-ce que pour savoir où se
    trouvent certains fichiers. Cela ne devrait pas présenter de grandes
    difficultés, et nous essaierons de clarifier tout ça lorsque le besoin
    s'en fera sentir.
    

    
    Enfin, vous devrez vous assurer que les modules
    mod_authn_core et mod_authz_core
    ont été soit compilés avec le binaire httpd, soit chargés par le
    fichier de configuration httpd.conf. Ces deux modules fournissent
    des directives générales et des fonctionnalités qui sont critiques
    quant à la configuration et l'utilisation de l'authentification et
    de l'autorisation au sein du serveur web.

    Mise en oeuvre
    
    
    Nous décrivons ici les bases de la protection par mot de passe
    d'un répertoire de votre serveur.
    

    
    Vous devez en premier lieu créer un fichier de mots de passe. La
    méthode exacte selon laquelle vous allez créer ce fichier va varier
    en fonction du fournisseur d'authentification choisi. Mais nous
    entrerons dans les détails plus loin, et pour le moment, nous nous
    contenterons d'un fichier de mots de passe en mode texte.
    

    
    Ce fichier doit être enregistré à un endroit non accessible
    depuis le web, de façon à ce que les clients ne puissent pas le
    télécharger. Par exemple, si vos documents sont servis à partir de
    /usr/local/apache/htdocs, vous pouvez enregistrer le
    fichier des mots de passe dans
    /usr/local/apache/passwd.
    

    
    L'utilitaire htpasswd fourni avec Apache
    permet de créer ce fichier. Vous le trouverez dans le répertoire
    bin de votre installation d'Apache. Si vous avez
    installé Apache à partir d'un paquetage tiers, il sera probablement
    dans le chemin par défaut de vos exécutables.
    

    
    Pour créer le fichier, tapez :
    

    
    
      htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
    

    
    htpasswd vous demandera d'entrer le mot de
    passe, et de le retaper pour confirmation :
    

    
    
      # htpasswd -c /usr/local/apache/passwd/passwords rbowen
    
      New password: mot-de-passe
    
      Re-type new password: mot-de-passe
    
      Adding password for user rbowen
    
    

    
    Si htpasswd n'est pas dans le chemin par
    défaut de vos exécutables, vous devrez bien entendu entrer le chemin
    complet du fichier. Dans le cas d'une installation par défaut, il se
    trouve à /usr/local/apache2/bin/htpasswd.
    

    
    Ensuite, vous allez devoir configurer le serveur de façon à ce
    qu'il demande un mot de passe et lui préciser quels utilisateurs ont
    l'autorisation d'accès. Pour ce faire, vous pouvez soit éditer le
    fichier httpd.conf, soit utiliser un fichier
    .htaccess. Par exemple, si vous voulez protéger le
    répertoire /usr/local/apache/htdocs/secret, vous pouvez
    utiliser les directives suivantes, soit dans le fichier
    /usr/local/apache/htdocs/secret/.htaccess, soit dans le
    fichier httpd.conf à l'intérieur d'une section <Directory
    "/usr/local/apache/htdocs/secret"> :
    

    
    AuthType Basic
AuthName "Restricted Files"
# (Following line optional)
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
Require user rbowen
    


    
    Examinons ces directives une à une. La directive AuthType définit la méthode
    utilisée pour authentifier l'utilisateur. La méthode la plus
    courante est Basic, et elle est implémentée par
    mod_auth_basic. Il faut cependant garder à l'esprit
    que l'authentification Basic transmet le mot de passe depuis le
    client vers le serveur en clair. Cette méthode ne devra donc pas
    être utilisée pour la transmission de données hautement sensibles si
    elle n'est pas associée au module mod_ssl. Apache
    supporte une autre méthode d'authentification : AuthType
    Digest. Cette méthode est implémentée par le module mod_auth_digest et a été conçue pour
    améliorer la sécurité. Ce but n'a cependant pas été atteint et il est préférable
    de chiffrer la connexion avec mod_ssl.
    

    
    La directive AuthName définit
    l'Identificateur (Realm) à utiliser avec
    l'authentification. L'identificateur possède deux fonctions. Tout
    d'abord, le client présente en général cette information à
    l'utilisateur dans le cadre de la boîte de dialogue de mot de passe.
    Ensuite, le client l'utilise pour déterminer quel mot de passe
    envoyer pour une zone authentifiée donnée.
    

    
    Ainsi par exemple, une fois un client authentifié dans la zone
    "Fichiers réservés", il soumettra à nouveau
    automatiquement le même mot de passe pour toute zone du même serveur
    marquée de l'identificateur "Fichiers réservés". De
    cette façon, vous pouvez éviter à un utilisateur d'avoir à saisir
    plusieurs fois le même mot de passe en faisant partager le même
    identificateur entre plusieurs zones réservées. Bien entendu et pour
    des raisons de sécurité, le client devra redemander le mot
    de passe chaque fois que le nom d'hôte du serveur sera modifié.
    

    
    La directive AuthBasicProvider est, dans ce
    cas, facultative, car file est la valeur par défaut
    pour cette directive. Par contre, cette directive sera obligatoire
    si vous utilisez une autre source d'authentification comme
    mod_authn_dbm ou
    mod_authn_dbd.
    

    
    La directive AuthUserFile définit le chemin
    du fichier de mots de passe que nous venons de créer avec
    htpasswd. Si vous possédez un grand nombre
    d'utilisateurs, la durée de la recherche dans un fichier texte pour
    authentifier un utilisateur à chaque requête va augmenter
    rapidement, et pour pallier cet inconvénient, Apache peut aussi
    stocker les données relatives aux
    utilisateurs dans des bases de données rapides. Le module
    mod_authn_dbm fournit la directive AuthDBMUserFile. Les programmes dbmmanage et htdbm permettent de
    créer et manipuler ces fichiers. Enfin, de nombreux modules tiers
    fournissent d'autres types d'authentification.
    

    
    Enfin, la directive Require implémente la partie
    autorisation du processus en définissant l'utilisateur autorisé à
    accéder à cette zone du serveur. Dans la section suivante, nous
    décrirons les différentes méthodes d'utilisation de la directive
    Require.
    

    top
    

    

    Autorisation d'accès à
plusieurs personnes
    
    
    Les directives ci-dessus n'autorisent qu'une personne (quelqu'un
    possédant le nom d'utilisateur rbowen) à accéder au
    répertoire. Dans la plupart des cas, vous devrez autoriser
    l'accès à plusieurs personnes. C'est ici
    qu'intervient la directive AuthGroupFile.
    

    
    Si vous voulez autoriser l'accès à plusieurs personnes, vous
    devez créer un fichier de groupes qui associe des noms de groupes
    avec une liste d'utilisateurs de ce groupe. Le format de ce fichier
    est très simple, et vous pouvez le créer avec votre éditeur favori.
    Son contenu se présente comme suit :
    

   
    
     Nom-de-groupe: rbowen dpitts sungo rshersey
   
    

    
    Il s'agit simplement une liste des membres du groupe sous la
    forme d'une ligne séparée par des espaces.
    

    
    Pour ajouter un utilisateur à votre fichier de mots de passe
    préexistant, entrez :
    

    
    
      htpasswd /usr/local/apache/passwd/passwords dpitts
    
    

    
    Vous obtiendrez le même effet qu'auparavant, mais le mot de passe
    sera ajouté au fichier, plutôt que d'en créer un nouveau (C'est le
    drapeau -c qui permet de créer un nouveau fichier de
    mots de passe)..
    

    
    Maintenant, vous devez modifier votre fichier
    .htaccess ou la section <Directory> comme suit :
    

    
    AuthType Basic
AuthName "By Invitation Only"
# Optional line:
AuthBasicProvider file
AuthUserFile "/usr/local/apache/passwd/passwords"
AuthGroupFile "/usr/local/apache/passwd/groups"
Require group GroupName
    


    
    Maintenant, quiconque appartient au groupe
    Nom-de-groupe, et possède une entrée dans le fichier
    password pourra accéder au répertoire s'il tape le bon
    mot de passe.
    

    
    Il existe une autre méthode moins contraignante pour autoriser
    l'accès à plusieurs personnes. Plutôt que de créer un fichier de
    groupes, il vous suffit d'ajouter la directive suivante :
    

    
    Require valid-user
    


    
    Le remplacement de la ligne Require user rbowen par
    la ligne Require valid-user autorisera l'accès à
    quiconque possédant une entrée dans le fichier password, et ayant
    tapé le bon mot de passe.
    

    top
    

    

    Problèmes possibles
    
    
    L'authentification Basic est spécifiée d'une telle manière que
    vos nom d'utilisateur et mot de passe doivent être vérifiés chaque
    fois que vous demandez un document au serveur, et ceci même si vous
    rechargez la même page, et pour chaque image contenue dans la page
    (si elles sont situées dans un répertoire protégé). Comme vous
    pouvez l'imaginer, ceci ralentit un peu le fonctionnement. La mesure
    dans laquelle le fonctionnement est ralenti est proportionnelle à la
    taille du fichier des mots de passe, car ce dernier doit être ouvert
    et la liste des utilisateurs parcourue jusqu'à ce que votre nom soit
    trouvé, et ceci chaque fois qu'une page est chargée.
    

    
    En conséquence, ce ralentissement impose une limite pratique au
    nombre d'utilisateurs que vous pouvez enregistrer dans un fichier de
    mots de passe. Cette limite va varier en fonction des performances
    de votre serveur, mais vous commencerez à remarquer un
    ralentissement lorsque vous atteindrez quelques centaines
    d'utilisateurs, et serez alors appelés à utiliser une méthode
    d'authentification différente.
    

    top
    

    

    Autre méthode de stockage des mots de
passe
    

    
    Suite au problème évoqué précédemment et induit par le stockage
    des mots de passe dans un fichier texte, vous pouvez être appelé à
    stocker vos mots de passe d'une autre manière, par exemple dans une
    base de données.
    

    
    Pour y parvenir, on peut utiliser les modules
    mod_authn_dbm ou mod_authn_dbd.
    Vous pouvez choisir comme format de stockage dbm ou
    dbd à la place de file pour la directive
    AuthBasicProvider.
    

    
    Par exemple, pour sélectionner un fichier dbm à la place d'un
    fichier texte :
    

    
    <Directory "/www/docs/private">

    AuthName "Private"
    AuthType Basic
    AuthBasicProvider dbm
    AuthDBMUserFile "/www/passwords/passwd.dbm"
    Require valid-user

</Directory>
    


    
    D'autres options sont disponibles. Consultez la documentation de
    mod_authn_dbm pour plus de détails.
    

    top
    

    

    Utilisation de plusieurs fournisseurs
d'authentification
    

    
    Depuis l'arrivée des nouvelles architecture d'autorisation et
    d'authentification basées sur les fournisseurs, vous n'êtes plus
    limité à une méthode d'authentification et d'autorisation
    unique. En fait, on peut panacher autant de fournisseurs que l'on
    veut, ce qui vous permet d'élaborer l'architecture qui correspond
    exactement à vos besoins. Dans l'exemple suivant, on utilise
    conjointement les fournisseurs d'authentification
    file et LDAP :
    

    
    <Directory "/www/docs/private">

    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file ldap
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    Require valid-user

</Directory>
    


    
    Dans cet exemple, le fournisseur file va tenter d'authentifier
    l'utilisateur en premier. S'il n'y parvient pas, le fournisseur LDAP
    sera sollicité. Ceci permet l'élargissement des possibilités
    d'authentification si votre organisation implémente plusieurs types
    de bases d'authentification. D'autres scénarios d'authentification
    et d'autorisation peuvent associer un type d'authentification avec
    un autre type d'autorisation. Par exemple, une authentification
    basée sur un fichier de mots de passe peut permettre l'attribution
    d'autorisations basée sur un annuaire LDAP.
    

    
    Tout comme plusieurs fournisseurs d'authentification peuvent être
    implémentés, on peut aussi utiliser plusieurs méthodes
    d'autorisation. Dans l'exemple suivant, on utilise à la fois une
    autorisation à base de fichier de groupes et une autorisation à base
    de groupes LDAP.
    

    
    <Directory "/www/docs/private">

    AuthName "Private"
    AuthType Basic
    AuthBasicProvider file
    AuthUserFile "/usr/local/apache/passwd/passwords"
    AuthLDAPURL ldap://ldaphost/o=yourorg
    AuthGroupFile "/usr/local/apache/passwd/groups"
    Require group GroupName
    Require ldap-group cn=mygroup,o=yourorg

</Directory>
    


    
    Pour un scénario d'autorisation un peu plus avancé, des
    directives de conteneur d'autorisation comme <RequireAll> et
    <RequireAny> permettent d'appliquer une
    logique telle que l'ordre dans lequel les autorisations sont
    appliquées peut être entièrement contrôlé au niveau de la
    configuration. Voir Conteneurs
    d'autorisations pour un exemple de ce contrôle.
    


    top
    

    

    Pour aller plus loin qu'une simple
autorisation
    

    
    La manière dont les autorisations sont accordées est désormais
    beaucoup plus souple qu'une simple vérification auprès d'une seule
    base de données. Il est maintenant possible de choisir l'ordre, la
    logique et la manière selon lesquels une autorisation est
    accordée.
    

    
    Appliquer logique et
    ordonnancement
    
        
    Le contrôle de la manière et de l'ordre selon lesquels le
	processus d'autorisation était appliqué
	constituait une sorte de mystère par
	le passé. Dans Apache 2.2, un mécanisme d'authentification basé
	sur les fournisseurs a été développé afin de séparer le
	véritable processus d'authentification de l'autorisation et ses
	différentes fonctionnalités. Un des avantages colatéraux
	résidait dans le fait que les fournisseurs d'authentification
	pouvaient être configurés et appelés selon un ordre particulier
	indépendant de l'ordre de chargement du module auth proprement
	dit. Ce mécanisme basé sur les fournisseurs a été étendu au
	processus d'autorisation. Ceci signifie que la directive
	Require définit
	non seulement quelles méthodes d'autorisation doivent être
	utilisées, mais aussi l'ordre dans lequel elles sont appelées.
	Les méthodes d'autorisation sont appelées selon l'ordre dans
	lequel les directives Require apparaissent dans la
	configuration.
    

        
    Avec l'introduction des directives de conteneur
	d'autorisations <RequireAll>
 	et <RequireAny>, la
	configuration contrôle aussi le moment où les méthodes
	d'autorisation sont appelées, et quels critères déterminent
	l'autorisation d'accès. Voir Conteneurs
	d'autorisations pour un exemple de la manière de les
	utiliser pour exprimer des logiques d'autorisation
	complexes.
    

        
    Par défaut, toutes les directives Require sont
	traitées comme si elles étaient contenues dans une directive
	<RequireAny>. En d'autres termes, il
	suffit
	qu'une méthode d'autorisation s'applique avec succès pour que
	l'autorisation soit accordée.
    

    

    
    Utilisation de fournisseurs
    d'autorisation pour le contrôle d'accès
    
        
    La vérification du nom d'utilisateur et du mot de passe ne
	constituent qu'un aspect des méthodes d'authentification.
	Souvent, le contrôle d'accès à certaines personnes n'est pas
	basé sur leur identité ; il peut dépendre, par exemple de leur
	provenance.
    

        
    Les fournisseurs d'autorisation all,
	env, host et ip vous
	permettent d'accorder ou refuser l'accès en
	fonction de critères tels que le nom d'hôte ou l'adresse
	IP de la machine qui effectue la requête.
    

        
    L'utilisation de ces fournisseurs est spécifiée à l'aide de
	la directive Require. Cette directive
	permet d'enregistrer quels fournisseurs d'autorisation
	seront appelés dans le processus d'autorisation au cours du
	traitement de la requête. Par exemple :
    

        
    Require ip address
    


        
    où adresse est une adresse IP (ou une adresse IP
	partielle) ou :
    

        
    Require host domain_name
    


        
    où nom_domaine est un nom de domaine entièrement
	qualifé (ou un nom de domaine partiel) ; vous pouvez indiquer
	plusieurs adresses ou noms de domaines, si vous le désirez.
    

        
    Par exemple, si vous voulez rejeter les spams dont une
	machine vous inonde, vous pouvez utiliser ceci :
    

        
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>
    


        
    Ainsi, les visiteurs en provenance de cette adresse ne
	pourront pas voir le contenu concerné par cette directive. Si,
	par contre, vous connaissez le nom de la machine, vous pouvez
	utiliser ceci :
    

        
    <RequireAll>
    Require all granted
    Require not host host.example.com
</RequireAll>
    


        
    Et si vous voulez interdire l'accès à toutes les machines
	d'un domaine, vous pouvez spécifier une partie seulement de
	l'adresse ou du nom de domaine :
    

        
    <RequireAll>
    Require all granted
    Require not ip 192.168.205
    Require not host phishers.example.com moreidiots.example
    Require not host ke
</RequireAll>
    


        
    L'utilisation de la directive <RequireAll>
	avec de multiples directives <Require>, toutes avec la négation
	not, n'accordera l'accès que si toutes les
	conditions négatives sont vérifiées. En d'autres termes, l'accès
	sera refusé si au moins une des conditions négatives n'est pas
	vérifiée.
    

    

    
    Compatibilité ascendante du contrôle
    d'accès
    
        
    L'adoption d'un mécanisme à base de fournisseurs pour
	l'authentification, a pour effet colatéral de rendre inutiles
	les directives Order, Allow, Deny et Satisfy. Cependant, et à
	des fins de compatibilité ascendante vers les anciennes
	configurations, ces directives ont été déplacées vers le module
	mod_access_compat.
    

    
    Note
    
      
    Les directives fournies par le module
      mod_access_compat sont devenues obsolètes depuis
      la refonte du module mod_authz_host. Mélanger d'anciennes
      directives comme Order, Allow ou Deny avec des nouvelles comme
      Require est techniquement
      possible mais déconseillé. En effet, mod_access_compat a
      été conçu pour supporter des configurations ne contenant que des anciennes
      directives afin de faciliter le passage à la version 2.4. Voir le document
      upgrading pour plus de détails.

    Mise en cache de l'authentification
    
    
    Dans certains cas, l'authentification constitue une charge
    inacceptable pour un fournisseur d'authentification ou votre réseau.
    Ceci est susceptible d'affecter les utilisateurs du module
    mod_authn_dbd (ou les fournisseurs
    tiers/personnalisés). Pour résoudre ce problème, HTTPD 2.3/2.4
    propose un nouveau fournisseur de mise en cache,
    mod_authn_socache, qui permet de mettre en cache
    les données d'authentification, et ainsi réduire la charge du/des
    fournisseurs(s) originels.
    
    
    Cette mise en cache apportera un gain en performance substantiel
    à certains utilisateurs.
    

    top
    

    

    Pour aller plus loin . . .
    
    
    Vous pouvez aussi lire la documentation de
    mod_auth_basic et mod_authz_host
    qui contient des informations supplémentaires à propos du
    fonctionnement de tout ceci.
    Certaines configurations d'authentification peuvent aussi être
    simplifiées à l'aide de la directive <AuthnProviderAlias>.
    

    
    Les différents algorithmes de chiffrement supportés par Apache
    pour authentifier les données sont expliqués dans PasswordEncryptions.
    

    
    Enfin vous pouvez consulter la recette Contrôle
    d'accès, qui décrit un certain nombre de situations en relation

    En sistemas con múltiples usuarios, cada usuario puede tener un website 
    en su directorio home usando la directiva UserDir. Los visitantes de una URL 
    http://example.com/~username/ recibirán el contenido del 
    directorio home del usuario "username", en el subdirectorio 
    especificado por la directiva UserDir.
    

	
    Tenga en cuenta que, por defecto, el acceso a estos directorios 
    NO está activado. Puede permitir acceso cuando usa 
    UserDir quitando el comentario de la línea:
    

    
    #Include conf/extra/httpd-userdir.conf
    


    
    En el fichero por defecto de configuración conf/httpd.conf, 
    y adaptando el fichero httpd-userdir.conf según sea necesario, 
    o incluyendo las directivas apropiadas en un bloque 
    <Directory> dentro del fichero 
    principal de configuración.

    Configurando la ruta del fichero con UserDir
    
    

    
    La directiva UserDir
    especifica un directorio del que cargar contenido por usuario. Esta directiva 
    puede tener muchas formas distintas.
    

    
    Si se especifica una ruta que no empieza con una barra ("/"), se asume que 
      va a ser una ruta de directorio relativa al directorio home del usuario 
      especificado. Dada ésta configuración:
    

    
    UserDir public_html
    


    
    La URL http://example.com/~rbowen/file.html se traducirá en 
    la ruta del fichero /home/rbowen/public_html/file.html
    

    
    Si la ruta que se especifica comienza con una barra ("/"), la ruta del 
      directorio se construirá usando esa ruta, más el usuario especificado en la 
      configuración:
    

    
    UserDir /var/html
    


    
    La URL http://example.com/~rbowen/file.html se traducirá en 
    la ruta del fichero /var/html/rbowen/file.html
    

    
    Si se especifica una ruta que contiene un asterisco (*), se usará una ruta 
      en la que el asterisco se reemplaza con el nombre de usuario. Dada ésta configuración:
    

    
    UserDir /var/www/*/docs
    


    
    La URL http://example.com/~rbowen/file.html se traducirá en 
    la ruta del fichero /var/www/rbowen/docs/file.html
    

    
    También se pueden configurar múltiples directorios o rutas de directorios.
    

    
    UserDir public_html /var/html
    


    
    Para la URL http://example.com/~rbowen/file.html,
    Apache buscará ~rbowen. Si no lo encuentra, Apache buscará
    rbowen en /var/html. Si lo encuentra, la URL de más 
    arriba se traducirá en la ruta del fichero 
    /var/html/rbowen/file.html
    

  
    top
    

    

    Redirigiendo a URLs externas
    
    
    
    La directiva UserDir puede 
    usarse para redirigir solcitudes de directorios de usuario a URLs externas.
    

    
    UserDir http://example.org/users/*/
    


    
    El ejemplo de aquí arriba redirigirá una solicitud para
    http://example.com/~bob/abc.html hacia
    http://example.org/users/bob/abc.html.
    
  
    top
    

    

    Restringiendo qué usuarios pueden usar esta característica
    
    

    
    Usando la sintaxis que se muestra en la documentación de UserDir, usted 
      puede restringir a qué usuarios se les permite usar esta funcionalidad:
    

    
    UserDir disabled root jro fish
    


    
    La configuración de aquí arriba permitirá a todos los usuarios excepto a 
      los que se listan con la declaración disabled. Usted puede, 
      del mismo modo, deshabilitar esta característica para todos excepto algunos 
      usuarios usando una configuración como la siguiente:
    

    
    UserDir disabled
UserDir enabled rbowen krietz
    


    
    Vea la documentación de UserDir para más 
    ejemplos.
    

  
    top
    

    

    Activando un directorio cgi para cada usuario
    
  

   
    Para dar a cada usuario su propio directorio cgi-bin, puede usar una directiva 
   	<Directory>
   para activar cgi en un subdirectorio en particular del directorio home del usuario.
    

    
    <Directory "/home/*/public_html/cgi-bin/">
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    


    
    Entonces, asumiendo que UserDir está configurado con la 
    declaración public_html, un programa cgi example.cgi 
    podría cargarse de ese directorio así:
    

    
    
    http://example.com/~rbowen/cgi-bin/example.cgi
    
    

    
    top
    

    

    Permitiendo a usuarios cambiar la configuración
    
    

    
    Si quiere permitir que usuarios modifiquen la configuración del servidor en 
    	su espacio web, necesitarán usar ficheros .htaccess para hacer 
    	estos cambios. Asegúrese de tener configurado AllowOverride con un valor suficiente que permita a 
    los usuarios modificar las directivas que quiera permitir. 
    Vea el tutorial de .htaccess para obtener detalles adicionales sobre cómo funciona.

    Ce document est le guide de l'utilisateur de l'implémentation de HTTP/2
    dans Apache httpd. Cette fonctionnalité en est au stade
    de production, et les interfaces et directives devraient donc être
    dorénavant relativement stables.

    Le protocole HTTP/2
    
    
    
    HTTP/2 est une évolution du protocole de la couche application le plus
    utilisé au monde, HTTP. Cette évolution permet en particulier une utilisation
    plus efficace des ressources réseau. Il ne modifie pas les aspects
    fondamentaux de HTTP (sa sémantique). Entre autres, il y a toujours des
    requêtes, des réponses et des en-têtes. Par conséquent, si vous connaissez
    HTTP/1, vous connaissez déjà 95% de HTTP/2.
    
    
    Beaucoup a déjà été écrit à propos de HTTP/2 et de son fonctionnement. La
    documentation la plus officielle est bien entendu sa RFC 7540 (ou cette version au format plus
    lisible). Vous trouverez ici une description des rouages de HTTP/2 dans
    leurs moindres détails.
    
    
    Le premier document à lire lorsqu'on ne connaît pas un mécanisme n'est
    cependant pas sa RFC. Il est préférable de comprendre tout d'abord ce
    que ce mécanisme est censé faire, et seulement ensuite de lire sa RFC
    pour comprendre comment il fonctionne. http2  explained de Daniel Stenberg
    (l'auteur de curl)
    est un bien meilleur document pour démarrer l'étude de HTTP/2. En outre, de
    nouveaux langages s'ajoutent régulièrement à sa liste de traductions
    disponibles !
    
    
    Si vous n'avez pas envie de le lire parce que vous le trouvez trop long,
    voici certains pièges à éviter et nouveaux termes à connaître avant de lire
    ce document :
    
    
      
        
    • A la différence de HTTP/1 qui est en texte pur, HTTP/2 est un
	protocole binaire, et alors que le premier est lisible par
	un humain (par exemple pour sniffer le trafic réseau), le second ne
	l'est pas. Voir la FAQ
	officielle pour plus de détails.
      • 
        
    • h2 correspond à HTTP/2 sur TLS (négociation de
	protocole via ALPN).
      • 
        
    • h2c correspond à HTTP/2 sur TCP.
      • 
	
    • Une frame ou trame est la plus petite unité de
	communication au sein d'une connexion HTTP/2 et comporte une en-tête et
	une séquence d'octets de longueur variable dont la structure correspond
	au type de trame. Voir la section
	correspondante de la documentation officielle pour plus de
	détails.
      • 
        
    • Un stream est un flux bidirectionnel de frames au
	sein d'une connexion HTTP/2. La notion correspondante dans HTTP/1 est un
	échange de messages de type requête et réponse. Voir la section
	correspondante de la documentation officielle pour plus de détails.
      • 
        
    • HTTP/2 peut gérer plusieurs streams de données sur
	la même connexion TCP, ce qui permet d'éviter le point de blocage
	classique de HTTP/1 pour les requêtes lentes, et de ne pas avoir à
	ouvrir de nouvelles connexions TCP pour chaque requête/réponse (les
	connexions persistantes ou KeepAlive avaient contourné le problème dans
	HTTP/1 mais ne l'avaient pas entièrement résolu)
      •

    HTTP/2 dans Apache httpd
    
    
    
    Le protocole HTTP/2 est implémenté dans Apache httpd via un module
    propre, pertinemment nommé mod_http2. Ce
    module implémente toutes les fonctionnalités décrites par la RFC 7540 et
    supporte les connexions en texte pur (http:), ou sécurisées (https:).
    La variante texte pur se nomme 'h2c', et la variante sécurisée
    'h2'. h2c peut être en mode direct ou
    Upgrade: via une requête initiale en HTTP/1.
    
    
    Server Push est une nouvelle fonctionnalité offerte
    aux développeurs web par HTTP/2. La section correspondante de ce document
    vous indiquera comment votre application peut en tirer parti.
    
  
    top
    

    

    Compilation de httpd avec le support de HTTP/2
    
    
    
    mod_http2 se base sur la bibliothèque
    de nghttp2 pour son implémentation. Pour
    pouvoir compiler mod_http2, libnghttp2 version
    1.2.1. ou supérieure doit être installée dans votre système.
    
    
    Pour déclencher la compilation de mod_http2, vous devez
    ajouter l'argument '--enable-http2' au script
    ./configure que vous exécutez à la racine de l'arborescence des
    sources de httpd. Si libnghttp2 est installée dans un
    répertoire non connu du chemin de vos bibliothèques, vous devez indiquer ce
    répertoire au script ./configure via l'argument
    '--with-nghttp2=<path>'.
    
    
    Alors que cette méthode de compilation conviendra à la plupart, certains
    préféreront lier statiquement nghttp2 à ce module. Pour ce
    faire, utilisez l'argument --enable-nghttp2-staticlib-deps.
    Cette méthode est pratiquement la même que celle utilisée pour lier
    statiquement openssl à mod_ssl.
    
    
    En parlant de SSL, vous devez savoir que la plupart des navigateurs ne
    communiqueront en HTTP/2 que sur des URLs sécurisées de type
    https: ; votre serveur doit donc supporter SSL. Mais de plus,
    votre bibliothèque SSL devra supporter l'extension ALPN. Enfin,
    si la bibliothèque que vous utilisez est OpenSSL, sa version devra être
    1.0.2. ou supérieure.
    
  
    top
    

    

    Configuration de base
    
    

    
    Maintenant que vous disposez d'un binaire httpd compilé avec le
    module mod_http2, l'activation de ce dernier nécessite un
    minimum de configuration supplémentaire. En premier lieu, comme pour tout
    module Apache, vous devez le charger :
    
    
    LoadModule http2_module modules/mod_http2.so
    


    
    La seconde directive que vous devez ajouter à votre fichier de
    configuration est
    
    
    Protocols h2 http/1.1
    

    
    Ceci permet de définir h2, la variante sécurisée, comme le protocole
    préféré pour les connexions à votre serveur. Si vous souhaitez que toutes les
    variantes soient disponibles, utilisez la directive suivante :
    
    
    Protocols h2 h2c http/1.1
    

    
    Selon l'endroit où vous placez cette directive, elle affectera l'ensemble
    de votre serveur, ou seulement un ou plusieurs serveurs virtuels. Vous
    pouvez aussi l'imbriquer comme dans l'exemple suivant :
    
    
    Protocols http/1.1
<VirtualHost ...>
    ServerName test.example.org
    Protocols h2 http/1.1
</VirtualHost>
    


    
    Seules les connexions en HTTP/1 seront alors permises, sauf pour le serveur
    virtuel test.example.org qui acceptera aussi les connexions SSL
    en HTTP/2.
    
    
    Utilisez une chaîne d'algorithmes de chiffrement forte
    
    
    La directive SSLCipherSuite doit
    être définie avec une chaîne d'algorithmes de chiffrement TLS forte. Même si
    la version actuelle de mod_http2 n'impose pas d'algorithmes
    de chiffrement particuliers, la plupart des clients le font. Faire pointer
    un navigateur vers un serveur où h2 est activé avec une chaîne
    d'algorithmes de chiffrement inappropriée entraînera un rejet et une
    retrogradation vers HTTP 1.1. C'est une erreur que l'on fait couramment
    lorsqu'on configure httpd pour HTTP/2 pour la première fois ; donc gardez la
    à l'esprit si vous voulez éviter de longues sessions de débogage ! Si vous
    voulez être sûr de définir une chaîne d'algorithmes de chiffrement
    appropriée, évitez ceux qui sont listés dans la  liste des
    algorithmes de chiffrement TLS HTTP/2 à proscrire.
    
    
    
    
    L'ordre des protocoles indiqués est aussi important. Par défaut, le
    premier sera le protocole préféré. Lorsqu'un client offre plusieurs choix,
    c'est le plus à gauche qui sera sélectionné. Dans
    
    
    Protocols http/1.1 h2
    

    
    le protocole préféré sera HTTP/1 et il sera toujours sélectionné sauf si
    un client ne supporte que h2. Comme nous souhaitons communiquer en
    HTTP/2 avec les clients qui le supportent, la meilleure définition de la
    directive est
    
    
    Protocols h2 h2c http/1.1
    


    
    Toujours à propos de l'ordre des protocoles, le client a lui aussi ses
    propres préférences en la matière. À ce titre, si vous le souhaitez, vous
    pouvez configurer votre serveur pour qu'il sélectionne non plus son
    protocole préféré, mais au contraire le protocole préféré
    du client :
    
    
    ProtocolsHonorOrder Off
    

    
    Avec cette directive, l'ordre des protocoles que vous avez
    défini devient caduque et seul l'ordre défini par le client sera pris en
    compte.
    
    
    Une dernière chose : les protocoles que vous définissez ne sont pas
    vérifiés quant à leurs validité ou orthographe. Vous pouvez très bien
    définir des protocoles qui n'existent pas, et il n'est donc pas nécessaire
    de filtrer le contenu de la directive Protocols avec des vérifications de type
    <IfModule>.
    
    
    Pour des conseils plus avancés à propos de la configuration, voir la Documentation de mod_http2, et en particulier
    la section à propos de la consommation supplémentaire de
    ressources, ainsi que la section expliquant comment gérer les serveurs multiples avec certificat
    commun.
    
  
    top
    

    

    Configuration du MPM
    
    

    
    Tous les modules multiprocessus (MPM) fournis avec httpd supportent
    HTTP/2. Cependant, si vous utilisez le MPM prefork, vous allez
    faire face à de sévères restrictions.
    
    
    Avec le MPM prefork, mod_http2 ne traitera
    qu'une requête à la fois par connexion alors que les clients tels que les
    navigateurs internet envoient de nombreuses requêtes au même moment. Si
    l'une d'entre elles est longue à traiter (ou implique une longue
    interrogation), les autres requêtes seront mises en attente.
    
    
    Par défaut, mod_http2 ne passe pas outre cette limitation pour
    la simple et bonne raison que le MPM prefork n'est aujourd'hui
    choisi que si vous exécutez des moteurs de traitement qui ne sont pas préparés
    pour le multithreading (par exemple qui se crashent lorsque plusieurs
    requêtes arrivent).
    
    
    Si votre plateforme et votre installation de httpd le supportent, la
    meilleur solution consiste actuellement à utiliser le MPM
    event.
    
    
    
    Si vous n'avez pas d'autre choix que d'utiliser le MPM
    prefork, mais souhaitez tout de même traiter plusieurs requêtes
    simultanément, vous pouvez jouer avec la directive H2MinWorkers, sans garantie que cela
    fonctionne.
    
  
    top
    

    

    Clients
    
    
    
    La plupart des navigateurs modernes supportent HTTP/2, mais seulement sur
    des connexions SSL : Firefox v43, Chrome v45, Safari v9, iOS Safari v9,
    Opera v35, Chrome pour Android v49 et
    Internet Explorer v11 sous Windows10 (selon cette source).
    
    
    D'autres clients et serveurs sont listés dans le wiki des
    implémentations ; entre autres des implémentations pour c, c++, common
    lisp, dart, erlang, haskell, java, nodejs, php, python, perl, ruby, rust,
    scala et swift.
    
    
    De nombreuses implémentations clientes autres que les navigateurs
    supportent HTTP/2 en texte pur, h2c. L'une des plus efficaces d'entre elles
    est curl.
    
  
    top
    

    

    Outils efficaces pour déboguer HTTP/2
    
    
    
    Le premier d'entre eux est bien entendu curl. Assurez-vous au préalable que votre
    version supporte HTTP/2 en vérifiant ses Fonctionnalités :
    
    
        $ curl -V
    curl 7.45.0 (x86_64-apple-darwin15.0.0) libcurl/7.45.0 OpenSSL/1.0.2d zlib/1.2.8 nghttp2/1.3.4
    Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 [...]
    Features: IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP HTTP2
    
    

    
    homebrew sous Mac OS :
    
    brew install curl --with-openssl --with-nghttp2
    
    
    
    Pour une inspection en profondeur : wireshark.
    
    
    Le paquet nghttp2 inclut aussi des
    outils comme :
    
    
      
        
    • nghttp
	- permet de visualiser les trames HTTP/2 et ainsi de se faire une meilleure
	  idée du protocole.
      • 
        
    • h2load -
	permet de tester votre serveur dans des conditions extremes.
      • 
    
    
    
    Chrome fournit des journaux détaillés des connexions HTTP/2 via la page
    special net-internals page. Il y
    a aussi cette extension intéressante pour Chrome
    et Firefox
    qui permet d'indiquer que votre navigateur utilise HTTP/2.
    
  
    top
    

    

    Push serveur
    
    
    
    Le protocole HTTP/2 permet au serveur de proposer (PUSH) des réponses
    pour lesquelles le client n'a rien demandé. La communication autour de ces
    réponses est du style : "voici une requête que vous n'avez jamais
    envoyée, et la réponse vous parviendra bientôt tout de même ..."
    
    
    Il y a cependant des conditions : le client peut désactiver cette
    fonctionnalité et le serveur ne pourra alors lui proposer des réponses que
    pour les requêtes qu'il a effectivement envoyées.
    
    
    Cette fonctionnalité a pour but de permettre au serveur d'envoyer au
    client des ressources dont il va probablement avoir besoin : par exemple une
    ressource css ou javascript appartenant à une page html que le client a
    demandée, un jeu d'images référencé par un css, etc...
    
    
    Cette anticipation a pour avantage de permettre au client d'économiser le
    temps qu'il lui aurait fallu pour envoyer une requête, quelques
    millisecondes à une demi-seconde en fonction de l'éloignement du serveur.
    Elle a cependant pour inconvénient d'imposer au client le téléchargement de
    ressources qu'il possède peut-être déjà dans son cache. Bien entendu, HTTP/2
    permet d'annuler prématurément de telles requêtes, mais des ressources sont
    tout de même gaspillées.
    
    
    En résumé : il n'existe pas encore de stratégie efficace pour faire le
    meilleur usage de cette fonctionnalité de HTTP/2 et tout le monde en est
    encore au stade de l'expérimentation. À ce titre, voici des conseils pour
    procéder vous-même à ces expérimentations :
    
    
    mod_http2 inspecte l'en-tête de la réponse et recherche les
    en-têtes Link sous un certain format :
    
    
    Link </xxx.css>;rel=preload, </xxx.js>; rel=preload
    

    
    Si la connexion supporte PUSH, ces deux ressources seront envoyées au
    client. En tant que développeur web vous pouvez définir ces en-têtes soit
    directement au niveau de la réponse de votre application, soit en
    configurant votre serveur via
    
    
    <Location /xxx.html>
    Header add Link "</xxx.css>;rel=preload"
    Header add Link "</xxx.js>;rel=preload"
</Location>
    

    
    Si vous souhaitez utiliser des liens preload sans déclencher
    de PUSH, vous pouvez utiliser le paramètre nopush comme suit :
    
    
    Link </xxx.css>;rel=preload;nopush
    

    
    Vous pouvez aussi désactiver les PUSHes pour l'ensemble de votre
    serveur via la directive
    
    
    H2Push Off
    

    
    À savoir aussi :
    
    
    Le module maintient un journal des ressources ayant fait l'objet d'un
    PUSH pour chaque connexion (en général des condensés hash des URLs), et
    n'effectuera pas deux fois un PUSH pour la même ressource. Cependant,
    lorsque la connexion est fermée, le journal de ses PUSHes est supprimé.
    
    
    Certains développeurs planchent sur la manière de permettre au client
    d'informer le serveur des ressources qu'il possède déjà dans son cache afin
    d'éviter les PUSHes pour ces dernières, mais ceci n'en est actuellement qu'à
    un stade très expérimental.
    
    
    L'
    en-tête Accept-Push-Policy est un autre dispositif expérimental
    implémenté dans mod_http2 ; il permet au client de définir pour
    chaque requête quels genres de PUSHes il accepte.
    
  

    
    
    La fonctionnalité PUSH n'apportera pas toujours le gain de performances dans
    l'obtention de réponses aux requêtes. Vous trouverez plusieurs études sur ce
    sujet sur internet qui en expliquent les avantages et inconvénients et
    comment les particularités des clients et du réseau en influencent le
    fonctionnement. Par exemple, le seul fait que le serveur PUSHes une
    ressource n'implique pas forcément que le navigateur l'utilisera.
    
    
    Ce qui influence le plus la réponse PUSHed, c'est la requête qui a été
    simulée. En effet, l'URL de la requête pour un PUSH est fournie par
    l'application, mais d'où viennent les en-têtes ? Par exemple, La requête
    PUSH requiert-elle un en-tête accept-language et si oui, quelle
    sera sa valeur ?
    
    
    httpd va consulter la requête originale (celle qui a déclenché le PUSH)
    et copier les en-têtes suivants vers la requête PUSH :
    user-agent, accept, accept-encoding,
    accept-language et cache-control.
    
    
    Tous les autres en-têtes sont ignorés. Les cookies eux non plus ne seront
    pas copiés. PUSHer des ressources qui requièrent la présence d'un cookie ne
    fonctionnera pas. Ceci peut être sujet à débat, mais tant que ce ne sera pas
    clairement discuté avec les navigateurs, restons prudents et évitons
    d'exposer les cookies là où ils ne sont pas censés être visibles.
    
  
    top
    

    

    Suggestions précoces
    
    
    
    A l'instar des ressources PUSHées, une autre méthode consiste à envoyer
    des en-têtes Link au client avant même que la réponse ne soit
    prête. Cette méthode utilise la fonctionnalité appelée "Suggestions
    précoces" (Early Hints) décrite dans la RFC 8297.
    
    
    Pour utiliser cette fonctionnalité, vous devez l'activer explicitement
    sur le serveur via :
    
    
    H2EarlyHints on
    

    
    Elle n'est en effet pas activée par défaut car certains navigateurs
    anciens perdent pied avec de telles réponses.
    
    
    Une fois cette fonctionnalité activée, vous pouvez utiliser la directive
    H2PushResource pour déclencher les
    suggestions précoces et les PUSHes de ressources :
    
    
    <Location /xxx.html>
    H2PushResource /xxx.css
    H2PushResource /xxx.js
</Location>
    

    
    Le serveur enverra alors au client une réponse "103 Early
    Hints" dès qu'il commencera à traiter la requête. Selon
    votre application web, cet envoi peut intervenir beaucoup plus tôt que le
    moment où les premiers en-têtes de réponse auront été déterminés.
    
    
    Si H2Push est activé, ceci
    déclenchera aussi le PUSH juste après la réponse 103. Mais si H2Push n'est pas activé, la réponse 103 sera
    quand-même envoyée au client.

    Introduction
    
 
    Modules ApparentésDirectives Apparentées
    

    
    Cet article traite des Inclusions Côté Serveur (Server Side
    Includes), plus communément appelés SSI. Vous trouverez ici la
    manière de configurer votre serveur pour permettre les SSI, ainsi
    qu'une introduction à quelques techniques SSI de base permettant
    d'ajouter du contenu dynamique à vos pages HTML préexistantes.
    

    
    La dernière partie de cet article sera consacrée aux
    configurations SSI plus avancées, telles que les expressions
    conditionnelles dans les directives SSI.

    Qu'est-ce que SSI ?
    

    
    SSI (Server Side Includes) est constitué de directives placées dans
    des pages HTML, et évaluées par le serveur au moment où les pages
    sont servies. Elles vous permettent d'ajouter du contenu généré
    dynamiquement à une page HTML préexistante, sans avoir à servir la
    page entière via un programme CGI, ou toute autre technologie de
    contenu dynamique.
    

    
    Par exemple, vous pouvez insérer la directive suivante dans une
    page HTML existante :
    

    
    
    <!--#echo var="DATE_LOCAL" -->
    
    

    
    Ainsi, lorsque la page sera servie, la directive sera évaluée et
    remplacée par sa valeur :

    Le choix entre l'utilisation des SSI et la génération entière de
    la page par un programme quelconque, est en général dicté par la
    proportion de contenu statique et de contenu devant être généré
    chaque fois que la page est servie. SSI est idéal pour ajouter de
    petites quantités d'information, comme l'heure courante dans
    l'exemple précédent. Mais si la
    plus grande partie de votre page est générée au moment où elle est
    servie, vous devez vous tourner vers une autre solution.
    

    top
    

    

    Configurer votre serveur pour permettre les SSI
    


    
    Pour permettre l'utilisation des SSI sur votre serveur, vous
    devez ajouter la directive suivante dans votre fichier
    httpd.conf, ou dans un fichier .htaccess
    :
    

    Options +Includes
    


    
    Cette directive indique à Apache que vous désirez permettre la
    recherche de directives SSI lors de l'interprétation des fichiers.
    Notez cependant que la plupart des configurations contiennent de
    nombreuses directives Options
    qui peuvent s'écraser les unes les autres. Vous devrez probablement
    appliquer ces directives Options au répertoire
    spécifique pour lequel vous voulez activer les SSI, afin d'être sûr
    qu'elles y seront bien activées.
    

    
    Tout fichier ne fera cependant pas l'objet de recherche de
    directives SSI. Vous devez indiquer à Apache quels fichiers seront
    concernés. Vous pouvez y parvenir en indiquant une extension, comme
    .shtml, à l'aide des directives suivantes :
    

    AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
    


    
    Un des désavantages de cette approche réside dans le fait que si
    vous voulez ajouter des directives SSI à une page préexistante, vous
    devrez changer le nom de cette page, et donc tout lien qui la
    contient, de façon à ce qu'elle possède l'extension
    .shtml, condition nécessaire pour que les directives
    SSI qu'elle contient soient traitées.
    

    
    Une autre méthode consiste à utiliser la directive XBitHack :
    

    XBitHack on
    


    
    La directive XBitHack
    indique à Apache qu'il doit rechercher des directivves SSI dans les
    fichiers si leur bit d'exécution est positionné. Il n'est ainsi plus
    nécessaire de changer le nom du fichier pour ajouter des directives
    SSI à une page préexistante ; vous devez simplement attribuer les
    droits d'exécution au fichier à l'aide de chmod.
    

    
        chmod +x pagename.html

    

    
    Un bref commentaire sur ce qu'il ne faut pas faire. Certaines
    personnes peuvent vous conseiller de tout simplement indiquer à
    Apache de rechercher des directives SSI dans tous les fichiers
    .html, ce qui vous évite d'avoir à gérer les noms de
    fichiers avec extension .shtml. Ils n'ont probablement
    pas entendu parler de la directive XBitHack. En effet, vous devez
    garder à l'esprit qu'en faisant ceci, Apache va devoir rechercher
    des directives SSI dans chaque fichier qu'il sert, même s'il n'en
    contient aucune. Ce n'est donc pas une bonne idée car les
    performances peuvent en être sensiblement affectées.
    

    
    Bien entendu, sous Windows, il n'y a pas de bit d'exécution à
    positionner, ce qui limite un peu vos choix.
    

    
    Dans sa configuration par défaut, Apache n'envoie pas la date de
    dernière modification ou les en-têtes HTTP relatifs à la taille des
    contenus dans les pages SSI, car ses valeurs sont difficiles à
    calculer pour les contenus dynamiques. Ceci peut induire une
    impression de diminution des performances côté client, en empêchant
    la mise en cache de votre document. Il existe deux méthodes pour
    résoudre ce problème :
    

    
      
      
    1. Utilisez la configuration XBitHack Full. Elle
      indique à Apache de déterminer la date de dernière modification en
      ne regardant que la date du fichier à l'origine de la requête,
      tout en ignorant la date de modification de tout fichier inclus.
      2. 

      
    2. Utilisez les directives fournies par le module
      mod_expires pour définir de manière explicite la
      date d'expiration de vos fichiers, laissant par la-même
      aux navigateurs et aux mandataires le soin de déterminer s'il est
      opportun ou non de les mettre en cache.
      3.

    Directives SSI de base
    

    
    Les directives SSI adoptent la syntaxe suivante :
    

    
        <!--#fonction attribut=valeur attribut=valeur ... -->

    

    
    Le format d'une directive SSI étant similaire à celui d'un
    commentaire HTML, si vous n'avez pas activé correctement SSI, le
    navigateur l'ignorera, mais elle sera encore visible dans le source
    HTML. Si SSI est correctement configuré, la directive sera remplacée
    par ses résultats.
    

    
    "fonction" peut prendre de nombreuses formes, et nous décrirons
    plus précisément la plupart d'entre eux dans la prochaine version de
    ce document. Pour le moment, voici quelques exemples de ce que vous
    pouvez faire avec SSI.
    


    La date courante
    


    
        <!--#echo var="DATE_LOCAL" -->

    

    
    La fonction echo permet d'afficher la valeur d'une
    variable. Il existe un grand nombre de variables standards, y
    compris l'ensemble des variables d'environnement disponibles pour
    les programmes CGI. De plus, vous pouvez définir vos propres
    variables à l'aide de la fonction set.
    

    
    Si vous n'aimez pas le format sous lequel la date s'affiche, vous
    pouvez utiliser la fonction config avec un attribut
    timefmt, pour le modifier.
    


    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        Today is <!--#echo var="DATE_LOCAL" -->

    



    Date de modification du fichier
    


    
        Dernière modification du document <!--#flastmod file="index.html" -->

    

    
    Le format peut là aussi être modifié à l'aide de l'attribut
    timefmt.
    



    Inclusion des résultats d'un programme CGI
    

    
    C'est le cas le plus courant d'utilisation des SSI - afficher les
    résultats d'un programme CGI, comme l'universellement adoré
    "compteur d'accès".
    


    
        <!--#include virtual="/cgi-bin/counter.pl" -->

    



    top
    

    

    Exemples additionnels
    


    
    Vous trouverez dans ce qui suit quelques exemples spécifiques de
    ce que vous pouvez faire de vos documents HTML avec SSI.
    


    Quand ce document a-t-il été modifié ?
    

    
    Nous avons mentionné plus haut que vous pouviez utiliser SSI pour
    informer l'utilisateur de la date de dernière modification du
    document. Cependant, la méthode pour y parvenir n'a pas été vraiment
    abordée. Placé dans votre document HTML, le code suivant va insérer
    un repère de temps dans votre page. Bien entendu, SSI devra avoir
    été correctement activé, comme décrit plus haut.
    

    
        <!--#config timefmt="%A %B %d, %Y" -->
    
        Dernière modification du fichier <!--#flastmod file="ssi.shtml" -->

    

    
    Bien entendu, vous devez remplacer ssi.shtml par le
    nom du fichier auquel vous faites référence. Ceci ne conviendra pas
    si vous recherchez un morceau de code générique que vous pourrez
    insérer dans tout fichier ; dans ce cas, il est préférable
    d'utiliser la variable LAST_MODIFIED :
    

    
        <!--#config timefmt="%D" -->
    
        This file last modified <!--#echo var="LAST_MODIFIED" -->

    

    
    Pour plus de détails sur le format timefmt, tapez
    strftime dans votre moteur de recherche préferé. La
    syntaxe est identique.
    



    Inclusion d'un pied de page standard
    


    
    Si le site que vous gérez comporte plus que quelques pages, vous
    allez vite vous apercevoir qu'effectuer des modifications sur toutes
    ces pages peut devenir très contraignant, en particulier si vous
    voulez qu'elles conservent un aspect homogène.
    

    
    Inclure un fichier pour un en-tête et/ou un pied de page peut
    simplifier cette corvée de mises à jour. Il vous suffit de
    confectionner un fichier de pied de page, et de l'inclure dans
    chaque page à l'aide de l'élément SSI include. Pour
    définir le fichier à inclure, la fonction include peut
    utiliser soit l'attribut file, soit l'attribut
    virtual. L'attribut file est un chemin de
    fichier relatif au répertoire courant. C'est à dire qu'il
    ne peut ni avoir pour valeur un chemin absolu (commençant par /), ni
    comporter "../" dans son chemin. L'attribut virtual est
    probablement plus commode, et peut spécifier une URL relative au
    document servi. Elle peut commencer par un /, mais le fichier inclus
    et le fichier servi doivent résider sur le même serveur.
    

    
        <!--#include virtual="/footer.html" -->

    

    
    Je combinerai souvent ces deux derniers points, en ajoutant une
    directive LAST_MODIFIED dans un fichier de pied de page
    destiné à être inclus. Le fichier inclus peut contenir des
    directives SSI, et les inclusions peuvent être imbriquées - à
    savoir, le fichier inclus peut inclure un autre fichier, etc...
    



    top
    

    

    Que puis-je configurer d'autre ?
    


    
    En plus du format de date, vous pouvez utiliser l'élément
    config pour configurer deux autres choses.
    

    
    En général, lorsque quelque chose se passe mal avec votre
    directive SSI, vous recevez le message :
    

    
        [an error occurred while processing this directive]

    

    
    Pour modifier ce message, vous pouvez utiliser l'attribut
    errmsg avec la fonction config :
    

    
        <!--#config errmsg="[Il semblerait que vous ne sachiez pas
	utiliser les SSI]" -->

    

    
    Il est cependant probable que les utilisateurs finaux ne voient
    jamais ce message, car vous aurez résolu tous les problèmes issus de
    vos directives SSI avant que votre site ne soit mis en production.
    (N'est-ce pas ?)
    

    
    Vous pouvez aussi modifier le format sous lequel les tailles de
    fichiers sont affichées à l'aide de l'attribut sizefmt.
    Vous pouvez spécifier bytes pour un affichage en
    octets, ou abbrev pour un affichage plus concis en Ko
    ou Mo, selon le cas.
    
    
    top
    

    

    Exécution de commandes
    
    

    
    Voici autre chose que vous pouvez faire avec la fonction
    exec. Vous pouvez vraiment faire exécuter une commande
    par SSI en utilisant le shell (/bin/sh, pour être plus
    précis - ou le shell DOS, si vous êtes sous Win32). Par exemple, ce
    qui suit vous permet d'afficher le contenu d'un répertoire.
    

    
        <pre>
    
        <!--#exec cmd="ls" -->
    
        </pre>

    

    
    ou, sous Windows
    

    
        <pre>
    
        <!--#exec cmd="dir" -->
    
        </pre>

    

    
    Vous noterez probablement l'étrange formatage provoqué par cette
    directive sous Windows, car la sortie de dir contient
    la chaîne  de caractères "<dir>", ce qui trompe le
    navigateur.
    

    
    Notez que cette fonctionnalité est très dangereuse, car elle va
    permettre d'exécuter tout code associé à l'élément
    exec. Si vous êtes dans la situation où les
    utilisateurs peuvent éditer le contenu de vos pages web, dans le cas
    d'un "livre d'or" par exemple, assurez-vous de désactiver cette
    fonctionnalité. Vous pouvez, tout en permettant les SSI, désactiver
    la fonctionnalité exec à l'aide de l'argument
    IncludesNOEXEC de la directive
    Options.
    
    
    top
    

    

    Techniques SSI avancées
    


    
    Outre l'affichage de contenu, les SSI d'Apache vous permettent de
    définir des variables, et de les utiliser dans des comparaisons et
    des conditions.
    


    Définition de variables
    

    
    Avec l'élément set, vous pouvez définir des
    variables pour un usage ultérieur. Comme nous en aurons besoin plus
    loin, nous allons en parler tout de suite. La syntaxe se présente
    comme suit :
    

    
        <!--#set var="name" value="Rich" -->

    

    
    Pour affecter une valeur à vos variables, en plus de la
    définition littérale de l'exemple ci-dessus, vous pouvez utiliser
    une autre variable, y compris les variables d'environnement, ou les variables
    décrites plus haut (comme LAST_MODIFIED par exemple).
    Pour indiquer qu'il s'agit d'une variable et non d'une chaîne, vous
    devez utiliser le symbole dollar ($) devant le nom de la
    variable.
    

    
     <!--#set var="modified" value="$LAST_MODIFIED" -->
    
    

    
    Pour insérer un caractère $ dans la valeur de votre variable,
    vous devez l'échapper à l'aide d'un backslash.
    

    
        <!--#set var="cost" value="\$100" -->

    

    
    Enfin, si vous voulez insérer une variable dans une chaîne, et
    s'il y a une chance pour que le nom de la variable se confonde avec
    le reste de la chaîne, vous pouvez l'entourer d'accolades pour
    eviter toute confusion (Il est difficile de trouver un bon exemple
    pour illustrer ceci, mais j'espère que vous comprendrez).
    

    
        <!--#set var="date" value="${DATE_LOCAL}_${DATE_GMT}" -->

    



    Expressions conditionnelles
    


    
    Maintenent que nous avons des variables, et que nous pouvons
    définir et comparer leurs valeurs, nous sommes à même de les
    utiliser dans des expressions conditionnelles. Ceci confère à SSI le
    statut de petit langage de programmation.
    mod_include fournit une structure if,
    elif, else, endif pour la
    construction d'expressions conditionnelles, ce qui vous permet de
    générer plusieurs pages logiques à partir d'une seule vraie
    page.
    

    
    La structure de l'expression conditionnelle est :
    

    
    <!--#if expr="condition" -->
    
    <!--#elif expr="condition" -->
    
    <!--#else -->
    
    <!--#endif -->

    

    
    Une condition peut revêtir la forme de toute comparaison
    logique - soit une comparaison de valeurs avec une autre, soit une
    vérification de la "vérité" d'une valeur particulière (Une chaîne
    donnée est vraie si elle n'est pas vide). Pour une liste exhaustive
    des opérateurs de comparaison disponibles, voir la documentation du
    module mod_include.
    

    
    Par exemple, spour insérer l'heure du jour dans votre page web,
    vous pouvez ajouter ces lignes dans la page HTML :
    

    
    
    Good
    <!--#if expr="%{TIME_HOUR} <12" -->
    
    morning!
    
    <!--#else -->
    
    afternoon!
    
    <!--#endif -->
    
    
        

    
    Toute autre variable (que vous avez définie, ou une variable
    d'environnement normale) peut être utilisée dans les expressions
    conditionnelles. Voir le document Expressions
    rationnelles dans le serveur HTTP Apache pour plus de détails à
    propos du fonctionnement du moteur d'évaluation des expressions
    rationnelles.
    
    
    
    Associée à la possibilité avec Apache de définir
    des variables d'environnement à l'aide de directives
    SetEnvIf, ainsi que d'autres directives en rapport,
    cette fonctionnalité vous permet d'ajouter une grande variété
    de contenus dynamiques côté serveur sans avoir à concevoir une
    application web de A à Z.
    


    top
    

    

    Conclusion
    

    
    SSI ne remplace certainement pas CGI, ou d'autres technologies
    utilisées pour la génération de pages web dynamiques. Mais c'est une
    bonne méthode pour ajouter des petits contenus dynamiques à vos
    pages, sans devoir fournir un gros effort supplémentaire.

    Modules ApparentésDirectives Apparentées
    
    
    Les fichiers .htaccess ne doivent être utilisés
    que si vous n'avez pas accès au fichier de configuration du serveur
    principal. L'utilisation des fichiers .htaccess
    ralentit le fonctionnement de votre serveur HTTP Apache. Il est toujours
    préférable de définir les directives que vous pouvez inclure dans un
    fichier .htaccess dans une section Directory, car elles produiront le
    même effet avec de meilleures performances.
    

    top
    

    

    Que sont ce fichiers, comment les utiliser ?
    


    
    Les fichiers .htaccess (ou "fichiers de
    configuration distribués") fournissent une méthode pour modifier la
    configuration du serveur au niveau d'un répertoire. Un fichier,
    contenant une ou plusieurs directives de configuration, est placé
    dans un répertoire de documents particulier, et ses directives
    s'appliquent à ce répertoire et à tous ses sous-répertoires.
    

    
    Note :
    
      
    Si vous voulez donner un autre nom à votre fichier
      .htaccess, vous pouvez le faire en utilisant la
      directive AccessFileName. Par
      exemple, si vous préférez nommer votre fichier
      .config, vous pouvez mettre ceci dans le fichier de
      configuration de votre serveur :
    

      
    AccessFileName ".config"
    

    
    

    
    En général, les fichiers .htaccess utilisent la même
    syntaxe que les fichiers de
    configuration principaux. Ce que vous pouvez mettre dans ces
    fichier est déterminé par la directive AllowOverride. Cette directive spécifie,
    sous forme de catégories, quelles directives seront traitées si
    elles se trouvent dans un fichier .htaccess. Si une
    directive est permise dans un fichier .htaccess file,
    la documentation de cette directive contiendra une section Override,
    spécifiant quelle valeur doit prendre AllowOverride pour que cette directive
    soit traitée.
    

    
    Par exemple, si vous regardez la documentation de la directive
    AddDefaultCharset, vous verrez
    que cette dernière est permise dans les fichiers
    .htaccess (Voir la ligne de contexte dans le résumé de
    la directive). La ligne Override indique
    FileInfo. Vous devez donc avoir au moins
    AllowOverride FileInfo pour que cette directive soit
    traitée dans les fichiers .htaccess.
    

    
    Exemple :
    
        
    
          Contexte :
          configuration du serveur, serveur virtuel, directory, .htaccess
        
    

        
    
          Override:
          FileInfo
        
    
      
    

    
    Si vous n'êtes pas sûr qu'une directive particulière soit permise
    dans un fichier .htaccess, lisez la documentation de
    cette directive, et consultez la ligne de contexte pour
    ".htaccess".
    
    
    top
    

    

    Quand doit-on (ne doit-on pas) utiliser
    les fichiers .htaccess ?
    

    
    En principe, vous ne devriez utiliser les fichiers
    .htaccess que lorsque vous n'avez pas accès au fichier de
    configuration du serveur principal. Par exemple, la fausse
    idée
    selon laquelle l'authentification de l'utilisateur devrait toujours
    être faite dans les fichiers .htaccess est très
    répandue. Il est aussi souvent avancé, ces dernières
    années, que les directives de mod_rewrite doivent
    être définies dans les fichiers .htaccess. Ceci est
    tout simplement faux. Vous pouvez configurer
    l'authentification des utilisateurs au niveau de la configuration du
    serveur principal, et c'est en fait cette méthode qui doit être
    privilégiée. De même, les directives de
    mod_rewrite fonctionneront mieux, à de nombreux égards,
    dans le contexte du serveur principal.
    

    
    Les fichiers .htaccess ne devraient être utilisés
    que dans le cas où les fournisseurs de contenu ont besoin de
    modifier la configuration du serveur au niveau d'un répertoire, mais
    ne possèdent pas l'accès root sur le système du serveur. Si
    l'administrateur du serveur ne souhaite pas effectuer des
    modifications de configuration incessantes, il peut être intéressant
    de permettre aux utilisateurs isolés d'effectuer eux-mêmes ces
    modifications par le biais de fichiers .htaccess. Ceci
    est particulièrement vrai dans le cas où le fournisseur d'accès à
    Internet héberge de nombreux sites d'utilisateurs sur un seul
    serveur, et souhaite que ces utilisateurs puissent modifier
    eux-mêmes leurs configurations.
    

    
    Cependant et d'une manière générale, il vaut mieux éviter
    d'utiliser les fichiers .htaccess. Tout élément de
    configuration que vous pourriez vouloir mettre dans un fichier
    .htaccess, peut aussi être mis, et avec la même
    efficacité, dans une section <Directory> du fichier de configuration de
    votre serveur principal.
    

    
    Il y a deux raisons principales d'éviter l'utilisation des
    fichiers .htaccess.
    

    
    La première est liée aux performances. Lorsque la directive
    AllowOverride est définie de
    façon à autoriser l'utilisation des fichiers .htaccess,
    httpd va rechercher leur présence dans chaque répertoire. Ainsi,
    permettre l'utilisation des fichiers .htaccess est déjà
    en soi une cause de dégradation des performances, que vous utilisiez
    effectivement ces fichiers ou non ! De plus, le fichier
    .htaccess est chargé en mémoire chaque fois qu'un
    document fait l'objet d'une requête.
    

    
    Notez aussi que httpd doit rechercher les fichiers
    .htaccess dans tous les répertoires de niveau
    supérieur, afin de rassembler toutes les directives qui s'appliquent
    au répertoire courant (Voir la section comment sont
    appliquées les directives). Ainsi, si un fichier fait l'objet
    d'une requête à partir d'un répertoire
    /www/htdocs/exemple, httpd doit rechercher les
    fichiers suivants :
    

    
    
      /.htaccess
    
      /www/.htaccess
    
      /www/htdocs/.htaccess
    
      /www/htdocs/exemple/.htaccess
    
    

    
    En conséquence, chaque accès à un fichier de ce répertoire
    nécessite 4 accès au système de fichiers supplémentaires pour
    rechercher des fichiers .htaccess, même si
    aucun de ces fichiers n'est présent. Notez que cet exemple ne peut
    se produire que si les fichiers .htaccess ont été
    autorisés pour le répertoire /, ce qui est rarement le
    cas.
    

    
    La seconde raison d'éviter l'utilisation des fichiers
    .htaccess est liée à la sécurité. Si vous permettez aux
    utilisateurs de modifier la configuration du serveur, il peut en
    résulter des conséquences sur lesquelles vous n'aurez aucun
    contrôle. Réfléchissez bien avant de donner ce privilège à vos
    utilisateurs. Notez aussi que ne pas donner aux utilisateurs les
    privilèges dont ils ont besoin va entraîner une augmentation des
    demandes de support technique. Assurez-vous d'avoir informé
    clairement vos utilisateurs du niveau de privilèges que vous leur
    avez attribué. Indiquer exactement comment vous avez défini la
    directive AllowOverride et
    diriger les utilisateurs vers la documentation correspondante vous
    évitera bien des confusions ultérieures.
    

    
    Notez que mettre un fichier .htaccess contenant une
    directive dans un répertoire /www/htdocs/exemple
    revient exactement au même que mettre la même directive dans une
    section Directory <Directory "/www/htdocs/exemple">
    du fichier de configuration de votre serveur principal :
    

    
    Fichier .htaccess dans
    /www/htdocs/exemple :
    

    
    Contenu du fichier .htaccess dans
    /www/htdocs/exemple
    AddType text/example ".exm"
    

    

    
    Section de votre fichier
    httpd.conf
    <Directory "/www/htdocs/example">
    AddType text/example .exm
</Directory>
    

    

    
    Cependant, la perte de performances sera moindre si vous
    définissez cette directive dans la configuration de
    votre serveur principal, car cette dernière ne sera chargée qu'une
    seule fois au moment du démarrage du serveur, alors qu'elle le sera
    à chaque accès dans le cas d'un fichier .htaccess.
    

    
    L'utilisation des fichiers .htaccess peut être
    entièrement désactivée en définissant la directive AllowOverride à none :
    

    
    AllowOverride None
    


    top
    

    

    Comment sont appliquées les directives ?
    

    
    Les directives de configuration situées dans un fichier
    .htaccess s'appliquent au répertoire dans lequel ce
    fichier .htaccess se trouve, ainsi qu'à tous ses
    sous-répertoires. Cependant, il est important de garder à l'esprit
    qu'il peut y avoir des fichiers .htaccess dans les
    répertoires de niveau supérieur. Les directives sont appliquées
    selon l'ordre dans lequel elles sont rencontrées. Ainsi, les
    directives d'un fichier .htaccess situé dans un
    répertoire particulier peuvent écraser les directives se trouvant
    dans des fichiers .htaccess situés à un niveau
    supérieur dans l'arborescence des répertoires. Et ces dernières
    peuvent elles-mêmes avoir écrasé des directives d'un fichier
    .htaccess situé à un niveau encore plus haut, ou dans
    le fichier de configuration du serveur principal.
    

    
    Exemple :
    

    
    Dans le répertoire /www/htdocs/exemple1 se trouve un
    fichier .htaccess contenant ce qui suit :
    

    
    Options +ExecCGI
    


    
    Note : "AllowOverride Options" doit être présent
    pour permettre l'utilisation de la directive "Options"  dans les fichiers
    .htaccess.
    

    
    Dans le répertoire /www/htdocs/exemple1/exemple2 se
    trouve un fichier .htaccess contenant ce qui suit
    :
    

    
    Options Includes
    


    
    Ainsi, à cause de ce second fichier .htaccess du
    répertoire /www/htdocs/exemple1/exemple2, l'exécution
    des CGI est interdite, car la dernière définition d'options
    Options Includes écrase toute autre définition
    d'options d'un fichier .htaccess situé dans un
    répertoire de niveau supérieur.
    

    
    Interactions entre les fichiers .htaccess
    et les fichiers de configuration du serveur principal
    

    
    Comme indiqué dans la documentation sur les Sections de configuration, les fichiers
    .htaccess peuvent écraser les directives des sections
    <Directory> pour
    le répertoire correspondant, mais peuvent eux-mêmes être écrasés
    par d'autres types de sections des fichiers de la
    configuration principale. Cette possibilité peut s'avérer utile pour
    forcer certaines configurations, même en cas de présence de l'option
    libérale AllowOverride. Par
    exemple, pour interdire l'exécution de scripts en autorisant la
    définition de toute autre option dans les fichiers
    .htaccess, vous pouvez utiliser :
    

    
    <Directory "/www/htdocs">
    AllowOverride All
</Directory>

<Location "/">
    Options +IncludesNoExec -ExecCGI
</Location>
    


    
    Dans cet exemple, on considère que le chemin défini par la
    directive DocumentRoot est
    /www/htdocs.
    



    top
    

    

    Exemple d'authentification
    

    
    Si vous accédez directement à ce point du document pour apprendre
    à effectuer une authentification, il est important de noter ceci. Il
    existe une fausse idée selon laquelle il serait nécessaire
    d'utiliser les fichiers .htaccess pour implémenter
    l'authentification par mot de passe. Ceci est tout simplement faux.
    Pour y parvenir, il est préférable de mettre les directives
    d'authentification dans une section <Directory> du fichier de configuration de
    votre serveur principal, et les fichiers .htaccess ne
    devraient être utilisés que dans le cas où vous n'avez pas accès au
    fichier de configuration du serveur principal. Voir ci-dessus pour savoir dans quels cas vous devez ou
    ne devez pas utiliser les fichiers .htaccess.
    

    
    Ceci étant dit, si vous pensez que vous devez quand-même utiliser
    un fichier .htaccess, vous pouvez utiliser la
    configuration suivante :
    

    
    Contenu du fichier .htaccess :
    

    
    AuthType Basic
AuthName "Password Required"
AuthUserFile "/www/passwords/password.file"
AuthGroupFile "/www/passwords/group.file"
Require group admins
    


    
    Notez que AllowOverride AuthConfig doit être présent
    pour que ces directives produisent leur effet.
    

    
    Vous pouvez vous référer au tutoriel sur
    l'authentification pour une description plus détaillée de
    l'authentification et de l'autorisation.
    

    top
    

    

    Exemple d'Inclusion Côté Serveur (Server Side
Includes - SSI)
    

    
    Les fichiers .htaccess sont aussi couramment
    utilisés pour activer les SSI pour un répertoire particulier. Pour y
    parvenir, on utilise les directives de configuration suivantes,
    placées dans un fichier .htaccess enregistré dans le
    répertoire considéré :
    

    
    Options +Includes
AddType text/html shtml
AddHandler server-parsed shtml
    


    
    Notez que AllowOverride Options et AllowOverride
    FileInfo doivent être tous les deux présents pour que ces
    directives puissent produire leur effet.
    

    
    Vous pouvez vous référer au tutoriel SSI
    pour une description plus détaillée des SSI.
    

    top
    

    

    Les règles de réécriture dans les fichiers .htaccess
    

    Sivous utilisez des directives RewriteRule dans un fichier
.htaccess, gardez à l'esprit que les choses sont légèrement
différentes dans un contexte de répertoire. En particulier, les règles
sont relatives au répertoire courant, et non à l'URI original. Considérez
les exemples suivants :
    


    # Dans httpd.conf
RewriteRule "^/images/(.+)\.jpg" "/images/$1.png"

# Dans un fichier .htaccess situé dans le répertoire racine de vos
# documents
RewriteRule "^images/(.+)\.jpg" "images/$1.png"

# Dans un fichier .htaccess situé dans le répertoire images/
RewriteRule "^(.+)\.jpg" "$1.png"
    



    On voit que si le fichier .htaccess se situe à la racine
de vos documents, le slash de tête est supprimé de la valeur de
remplacement spécifiée pour la règle RewriteRule, et que si le fichier
.htaccess se situe dans le répertoire images,
la chaîne /images/ disparaît de cette même valeur de
remplacement. Il doit donc en être de même dans votre expression
rationnelle.
    


    Veuillez vous référer à cette documentation
pour une étude détaillée de l'utilisation du module
mod_rewrite.
    


    top
    

    

    Exemple de CGI
    

    
    En fin de compte, vous avez décidé d'utiliser un fichier
    .htaccess pour permettre l'exécution des programmes CGI
    dans un répertoire particulier. Pour y parvenir, vous pouvez
    utiliser la configuration suivante :
    

    
    Options +ExecCGI
AddHandler cgi-script cgi pl
    


    
    Alternativement, si vous souhaitez que tous les fichiers d'un
    répertoire donné soient considérés comme des programmes CGI, vous
    pouvez utiliser la configuration suivante :
    

    
    Options +ExecCGI
SetHandler cgi-script
    


    
    Notez que AllowOverride Options et AllowOverride
    FileInfo doivent être tous les deux présents pour que ces
    directives puissent produire leur effet.
    

    
    Vous pouvez vous référer au tutoriel CGI
    pour une description plus détaillée de la configuration et de la
    proprammation CGI.
    


    top
    

    

    Résolution des problèmes
    

    
    De nombreuses raisons peuvent être à l'origine du fait que
    les directives que vous avez mises dans un fichier
    .htaccess ne produisent pas l'effet désiré.
    

    
    Le plus souvent, le problème vient du fait que la définition de
    la directive AllowOverride
    ne permet pas l'activation des directives de votre fichier
    .htaccess. Vérifiez si une directive
    AllowOverride None n'affecte pas le répertoire où se
    trouve votre fichier. Un bon test consiste à mettre des directives
    dont la syntaxe est erronée dans votre ficher .htaccess
    et de recharger la page. Si aucune erreur n'est générée par le
    serveur, il est pratiquement certain qu'une directive
    AllowOverride None affecte votre répertoire.
    

    
    Par contre, si vous obtenez des erreurs de serveur lorsque vous
    tentez d'accéder à des documents, consultez votre journal des
    erreurs de httpd. Il vous indiquera probablement que la directive
    utilisée dans votre fichier .htaccess n'est pas
    permise.
    


    
	[Fri Sep 17 18:43:16 2010] [alert] [client 192.168.200.51] /var/www/html/.htaccess: DirectoryIndex not allowed here

    
	
    Cela signifie soit que vous utilisez une directive qui n'est
	jamais permise dans les fichiers .htaccess, soit
	que vous n'avez tout simplement pas défini la directive
	AllowOverride à un niveau
	suffisant pour la directive que vous utilisez. Consultez la
	documentation de cette directive pour déterminer quel cas
	s'applique.
    

	
    Le journal des erreurs peut aussi vous signaler une erreur de
	syntaxe dans l'usage de la directive elle-même.
    

    
    
    [Sat Aug 09 16:22:34 2008] [alert] [client 192.168.200.51] /var/www/html/.htaccess: RewriteCond: bad flag delimiters
    
    

	
    Dans ce cas, le message d'erreur sera spécifique à l'erreur
	de syntaxe que vous avez commise.

    Arquivos .htaccess oferecem um meio de fazer mudanças
 nas configurações por-diretório.

    O que eles são/Como usá-los
    


    
    Os arquivos .htaccess (ou "arquivos de
    configuração distribuída") oferecem um meio de fazer mudanças nas
    configurações por-diretório. Um arquivo, contendo uma ou mais
    diretrizes de configurações, é colocado em um diretório 
    em particular, e as diretrizes se aplicam para aquele diretório e todos 
    os seu subdiretórios subseqüentes.
    

    
    Nota:
    
      
    Se você quiser renomear o seu arquivo .htaccess
      para outro nome, você deve usar a diretriz AccessFileName. Por exemplo, se você
      prefere que o arquivo se chame .config, então você 
      pode adicionar a seguinte linha ao seu arquivo de configuração
      do servidor:
    

      
    
        AccessFileName .config
      
    
    
    

    
    No geral, arquivos .htaccess usam a mesma sintaxe
    que os arquivos de
    configuração principal. O que você pode colocar nesses
    arquivos é determinado pele diretriz AllowOverride. Essa diretriz especifica,
    em categorias, quais diretrizes serão aceitas caso sejam
    encontradas em um arquivo .htaccess.  Se uma diretriz
    for permitida em um arquivo .htaccess, a documentação
    para essa diretriz irá conter uma seção Override,
    especificando que valor precisa estar em AllowOverride para que esta diretriz
    seja permitida.
    

    
    Por exemplo, se você procurar na documentação pela diretriz
    AddDefaultCharset, você
    achará que ela é permitida nos arquivos .htaccess.
    (Veja a linha Contexto no sumário das diretivas.) A
    linha Override lê
    FileInfo. Então, você deve ao menos ter
    AllowOverride FileInfo para que essa diretriz seja
    aceita nos arquivos .htaccess.
    

    
    Exemplo:
    
        
    
          Contexto:
          configuração do servidor, hospedeiros virtuais, diretório, .htaccess
        
    

        
    
          Override:
          FileInfo
        
    
      
    

    
    Se você estiver incerto se uma diretriz em particular é
    aceita em um arquivo .htaccess, procure na
    documentação por essa diretriz, e verifique a linha de
    Contexto por ".htaccess".
     
    top
    

    

    Quando (não) usar arquivos .htaccess
    

    
    No geral, você nunca deve usar arquivos .htaccess
    a não ser que você não tenha acesso ao arquivo de configuração
    principal do servidor. Existe, por exemplo, um erro de concepção
    que dita que a autenticação de usuários sempre deve
    ser feita usando os arquivos .htaccess. Esse
    simplesmente não é o caso. Você pode usar as configurações de
    autenticação de usuário no arquivo de configuração principal do
    servidor, e isso é, de fato, a maneira mais adequada de se fazer
    as coisas.
    

    
    Arquivos .htaccess devem ser usados em casos onde
    os provedores de conteúdo do site precisem fazer mudanças na
    configuração do servidor por-diretório, mas não tem
    acesso root ao sistema do servidor. Caso o administrador do 
    servidor não esteja disposto a fazer mudanças freqüentes nas
    configurações do servidor, é desejável permitir que os 
    usuários possam fazer essas mudanças através de arquivos
    .htaccess eles mesmos. Isso é particularmente
    verdade, por exemplo, em casos onde provedores estão fornecendo
    múltiplos sites para usuários em apenas uma máquina, e querem que
    seus usuários possam alterar suas configurações.
    

    
    No entanto, de modo geral, o uso de arquivos .htaccess
    deve ser evitado quando possível. Quaisquer configurações 
    que você considerar acrescentar em um arquivo .htaccess, podem
    ser efetivamente colocadas em uma seção <Directory> no arquivo principal de
    configuração de seu servidor.
    

    
    Existem duas razões principais para evitar o uso de arquivos
    .htaccess.
    

    
    A primeira delas é a performance. Quando AllowOverride é configurado para
    permitir o uso de arquivos .htaccess, o Apache procura
    em todos diretórios por arquivos .htaccess.  
    Logo, permitir arquivos .htaccess causa um impacto na 
    performance, mesmo sem você usá-los de fato! Além disso, 
    o arquivo .htaccess é carregado toda vez que um documento 
    é requerido.
    

    
    Além disso, note que o Apache precisa procurar pelos arquivos
    .htaccess em todos os diretórios superiores, para ter
    o complemento total de todas as diretivas que devem ser
    aplicadas. (Veja a seção como as diretrizes são
    aplicadas.) Então, se um arquivo de um diretório
    /www/htdocs/example é requerido, o Apache precisa
    procurar pelos seguintes arquivos:
    

    
    
      /.htaccess
    
      /www/.htaccess
    
      /www/htdocs/.htaccess
    
      /www/htdocs/example/.htaccess
    
    

    
    Assim, para cada acesso de arquivo fora desse diretório,
    existem 4 acessos ao sistema de arquivos adicionais, mesmo
    que nenhum desses arquivos estejam presentes. (Note que esse
    só será o caso se os arquivos .htaccess
    estiverem habilitados para /, o que
    normalmente não é o verdade.)
    

    
    A segunda consideração é relativa à segurança. 
    Você está permitindo que os usuários modifiquem as 
    configurações do servidor, o que pode resultar em mudanças 
    que podem fugir ao seu controle. Considere com cuidado se você quer 
    ou não dar aos seus usuários esses privilégios. Note também 
    que dar aos usuários menos privilégios que eles precisam, acarreta em 
    pedidos de suporte técnico adicionais. Tenha certeza que você comunicou
    aos usuários que nível de privilégios você os deu. 
    Especificar exatamente o que você configurou na diretriz AllowOverride, e direcioná-los para a
    documentação relevante, irá poupá-lo de muita confusão 
    depois.
    

    
    Perceba que é exatamente equivalente colocar o arquivo
    .htaccess em um diretório
    /www/htdocs/example contendo uma diretriz, e
    adicionar a mesma diretriz em uma seção Directory
    <Directory /www/htdocs/example> na configuração
    principal do seu servidor:
    

    
    Arquivo .htaccess em /www/htdocs/example:
    

    
    Conteúdo de um arquivo .htaccess em
    /www/htdocs/example
    
        AddType text/example .exm
    
    

    
    Seção do seu arquivo httpd.conf
    
      <Directory /www/htdocs/example>
    
      
        AddType text/example .exm
    
          
      </Directory>
    
    

    
    No entanto, adicionando isso ao seu arquivo de configuração do
    servidor resultará em uma menor perda de performance, na medida que
    a configuração é carregada no momento da inicialização do
    servidor, ao invés de toda que que um arquivo é requerido.
    

    
    O uso de arquivos .htaccess pode ser totalmente
    desabilitado, ajustando a diretriz AllowOverride para none:
    

    
    
      AllowOverride None
    
    

    top
    

    

    Como as diretrizes são aplicadas
    

    
    As diretrizes de configuração que se encontram em um arquivo
    .htaccess são aplicadas para o diretório no qual o
    arquivo .htaccess se encontra, e para todos os
    subdiretórios ali presentes. Mas, é importante lembrar também que
    podem existir arquivos .htaccess no diretórios
    superiores. As diretrizes são aplicadas na ordem que são
    achadas. Logo, um arquivo .htaccess em um diretório
    em particular, pode sobrescrever as diretrizes encontradas em um
    diretório acima deste em sua respectiva árvore. Estes, por sua vez,
    podem ter suas diretrizes sobrescritas por diretrizes ainda mais
    acima, ou no próprio arquivo de configuração principal do
    servidor.
    

    
    Exemplo:
    

    
    No diretório /www/htdocs/example1 nós temos
    um arquivo .htaccess contendo o seguinte:
    

    
    
       Options +ExecCGI
    
    

    
    (Nota: você deve ter "AllowOverride Options" para
    permitir o uso da diretriz "Options" nos arquivos
    .htaccess .)
    

    
    No diretório /www/htdocs/example1/example2 nós temos
    um arquivo .htaccess contendo:
    

    
    
       Options Includes
    
    

    
    Devido a esse segundo arquivo .htaccess, no
    diretório /www/htdocs/example1/example2, a execução
    de scripts CGI não é permitida, pois somente Options
    Includes está em efeito, o que sobrescreve completamente
    quaisquer outros ajustes previamente configurados.
    

    top
    

    

    Exemplo de Autenticação
    

    
    Se você veio diretamente à esta parte do documento para
    aprender como fazer autenticação, é importante notar uma
    coisa. Existe uma concepção errada, mas muito comum, de que é
    necessário o uso de arquivos .htaccess para implementar 
    a autenticação por senha. Este não é o caso. Colocar 
    diretrizes de senha em uma seção <Directory>, no seu arquivo principal de
    configuração do servidor, é a melhor maneira de se implementar
    isto, e os arquivos .htaccess devem ser usados apenas
    se você não tem acesso ao arquivo principal de configuração do
    servidor. Veja acima a discussão sobre quando
    você deve e quando não deve usar os arquivos
    .htaccess.
    

    
    Dito isso, se você ainda acredita que precisa usar um arquivo
    .htaccess, a configuração a seguir provavelmente
    funcionará para você.
    

    
    Conteúdo de um arquivo .htaccess:
    

    
    
      AuthType Basic
    
      AuthName "Password Required"
    
      AuthUserFile /www/passwords/password.file
    
      AuthGroupFile /www/passwords/group.file
    
      Require Group admins
    
    

    
    Note que AllowOverride AuthConfig precisa estar
    habilitado para que estas diretrizes tenham efeito.
    

    
    Por favor veja o tutorial de
    autenticação para uma discussão mais completa sobre
    autenticação e autorização.
    

    top
    

    

    Exemplo de Server Side Includes
    

    
    Outro uso comum de arquivos .htaccess é ativar o
    Server Side Includes para um diretório em particular. Isto pode
    ser feito com as seguintes diretrizes de configuração, colocadas em
    um arquivo .htaccess no diretório desejado:
    

    
    
       Options +Includes
    
       AddType text/html shtml
    
       AddHandler server-parsed shtml
    
    

    
    Note que ambos AllowOverride Options e
    AllowOverride FileInfo precisam estar habilitados
    para essas diretrizes terem efeito.
    

    
    Por favor veja o tutorial de SSI para
    uma discussão mais completa sobre server-side includes.
    

    top
    

    

    Exemplo de CGI
    

    
    Finalmente, você pode querer que um arquivo
    .htaccess permita a execução de programas CGI em um
    diretório em particular. Isto pode ser implementado com as
    seguintes configurações:
    

    
    
       Options +ExecCGI
    
       AddHandler cgi-script cgi pl
    
    

    
    Alternativamente, se você desejar que todos os arquivos de um
    dado diretório, sejam considerados programas CGI, isso pode ser
    feito com a seguinte configuração:
    

    
    
       Options +ExecCGI
    
       SetHandler cgi-script
    
    

    
    Note que ambos AllowOverride Options e
    AllowOverride FileInfo precisam estar habilitados
    para que essas diretrizes tenham quaisquer efeito.
    

    
    Por favor veja o tutorial de CGI
    tutorial para uma discussão mais completa sobre programação
    e configuração CGI.
    

    top
    

    

    Resolvendo Problemas
    

    
    Quando você adiciona diretrizes de configuração em um arquivo
    .htaccess, e não obtém o efeito desejado, existe uma
    série de pontos que podem estar errados.
    

    
    Mais comumente, o problema é que a diretriz AllowOverride não está habilitada
    corretamente para que as suas diretrizes de configurações sejam
    honradas. Verifique se você não possui AllowOverride
    None ajustado para o escopo do arquivo em questão. Um bom
    meio de testar isso é colocar "lixo" em seu arquivo
    .htaccess e recarregá-lo. Se não for gerado nenhum
    erro do servidor, certamente você tem AllowOverride
    None habilitado.
    

    
    Se, por outro lado, você está obtendo erros do servidor ao
    tentar acessar documentos, verifique o registro de erros do
    Apache. Ele provavelmente irá indicar que a diretriz usada em
    seu arquivo .htaccess não é permitida.
    Alternativamente, ele pode acusar erros de sintaxe que você terá
    que corrigir.

    複数のユーザのいるシステムでは、UserDir ディレクティブを使って
    各ユーザがホームディレクトリにウェブサイトを構築できるように設定することが
    可能です。URL http://example.com/~username/ を訪れた人は
    "username" というユーザの UserDir ディレクティブで指定された
    サブディレクトリからコンテンツを得ることになります。

    file as necessary, or by including the appropriate directives in a
    Directory block within the main config file.
    
    
    デフォルトではこれらのディレクトリへのアクセスは許可されていません。
    UserDir を使って有効にできます。
    有効にするには、デフォルトの設定ファイルで付随する
    httpd-userdir.conf ファイルが必要で、
    その中の次の行のコメントアウトを外して有効にするか、
    
    
    
    
      #Include conf/extra/httpd-userdir.conf
    
    
    
    あるいは、メインの設定ファイル中の Directory 
    ブロックの中に適切にディレクティブを記述しておきます。

    UserDir を使ってファイルのパスを設定する
    
    

    
    UserDir ディレクティブは
    ユーザ毎のコンテンツが読み込まれるディレクトリを指定します。
    このディレクティブはいろいろ違った形式を取ることができます。
    

    
    スラッシュで始まらないパスが与えられたときは、ユーザのホームディレクトリ
    からの相対パスとみなされます。次の設定があったときに:
    

    
    UserDir public_html
    


    
    URL http://example.com/~rbowen/file.html は
    パス /home/rbowen/public_html/file.html へ
    変換されます。
    

    
    パスがスラッシュで始まるときは、ディレクトリパスはそのパスに
    ユーザ名を加えたものからなります。次の設定のとき:
    

    
    UserDir /var/html
    


    
    URL http://example.com/~rbowen/file.html は
    パス /var/html/rbowen/file.html へ変換されます。
    

    
    アスタリスク (*) を含むパスが指定されたときは、アスタリスクを
    ユーザ名で置換したものが使用されます。このような設定だと:
    

    
    UserDir /var/www/*/docs
    


    
    URL http://example.com/~rbowen/file.html は
    パス /var/www/rbowen/docs/file.html へ変換されます。
    

    
    ディレクトリやディレクトリパスを複数設定することもできます。
    

    
    UserDir public_html /var/html
    



    
    http://example.com/~rbowen/file.html という
    URL に対しては ~rbowen を探します。見つからなければ、
    /var/html の下にある rbowen を探します。
    もし見つかれば上記の URL は /var/html/rbowen/file.html
    というファイルパスに変換されます。
    

  
    top
    

    

    外部 URL にリダイレクトする
    
    
    
    UserDir
    ディレクティブを使って外部 URL にリダイレクトすることもできます。
    

    
    UserDir http://example.org/users/*/
    


    
    
    上記例では http://example.com/~bob/abc.html
    へのリクエストは http://example.org/users/bob/abc.html
    にリダイレクトされます。
    
  
    top
    

    

    この機能を使用できるユーザを制限する
    
    

    
    UserDir のドキュメントに示されている構文を使うことで、
    どのユーザがこの機能を使うことができるかを制限することができます:
    

    
    
      UserDir enabled
    
      UserDir disabled root jro fish
    
    

    
    上の設定は dissabled 文のユーザ以外のすべてのユーザに
    対して UserDir の機能を有効にします。同様にして、以下のように
    数名のユーザ以外に対してこの機能を無効にすることもできます:
    

    
          UserDir disabled
    
      UserDir enabled rbowen krietz
    


    
    他の例は UserDir
    の説明を参照してください。
    

  
    top
    

    

    ユーザ毎の CGI ディレクトリ
    
  

   
    それぞれのユーザに専用の cgi-bin ディレクトリを与えるために、
    <Directory>
    を使ってユーザのホームディレクトリの指定された領域に対して CGI を有効に
    することができます。
    

    
    <Directory /home/*/public_html/cgi-bin/>
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    


    
    そして、UserDir が
    public_html に設定されていると仮定すると、
    そのディレクトリの CGI プログラム example.cgi
    は以下の様に呼び出されることができます:
    

    
    
    http://example.com/~rbowen/cgi-bin/example.cgi
    
    

    
    top
    

    

    ユーザによる設定変更を許可
    
    

    
    ユーザに彼らのウェブ空間でのサーバの設定の変更を許可する場合、
    ユーザは .htaccess ファイルを使って設定を変更する必要があります。
    AllowOverride の値を
    ユーザが変更することを許可したいディレクティブに対して十分なものに
    設定していることを確認してください。この機能がどのようにして動作しているか
    の詳細は .htaccess チュートリアル を読んで

    Contrôle d'accès
    

    

    Langues Disponibles:  en  |

    Le contrôle d'accès fait référence à tout concept de contrôle
    d'accès à une ressource quelconque. Il est distinct du processus d'authentification et d'autorisation.
    

    


    top
    

    

    Modules et directives concernés
    

    
    Plusieurs modules peuvent intervenir dans le contrôle d'accès.
    Les plus importants sont mod_authz_core et
    mod_authz_host. Ce document illustre aussi comment
    utiliser mod_rewrite pour le contrôle
    d'accès.
    


    top
    

    

    Contrôle d'accès en fonction de l'hôte du
client
    
    
    
    Si vous souhaitez restreindre l'accès à certaines parties de votre
    site web en fonction de l'addresse de l'hôte de vos visiteurs, le
    plus simple pour y parvenir consiste à utiliser le module
    mod_authz_host.
    
    

    
    La directive Require permet d'accorder ou
    d'interdire l'accès à certaines ressources de différentes manières.
    Ces critères d'accès, en conjonction avec les directives RequireAll, RequireAny, et RequireNone, peuvent être
    combinés d'une manière suffisamment complexe pour
    satisfaire votre politique de contrôle d'accès.
    

    
    
    Les directives Allow, Deny, et Order fournies par le module
    mod_access_compat sont obsolètes, et sont appelées à
    disparaître dans les versions futures. Il est donc déconseillé de
    les utiliser, et de se fier aux tutoriels qui recommandent leur
    utilisation.
    
    

    
    Les directives Require s'utilisent comme suit :
    

    
    Require host address
Require ip ip.address
    


    
    Dans la première forme, nom-hôte est un nom de domaine
    pleinement qualifié (fqdn), ou un nom de domaine partiel ; vous
    pouvez spécifier plusieurs noms de domaines, si vous le désirez.
    

    
    Dans la seconde forme, adresse-ip est une adresse IP
    complète, une adresse IP partielle, une paire réseau/masque de
    sous-réseau ou une spécification CIDR de la forme réseau/nnn. Il est
    possible de spécifier des adresses IPv4 ou IPv6.
    

    
    Voir la
    documentation de mod_authz_host pour d'autres exemples de cette
    syntaxe.
    

    
    Vous pouvez insérer le mot-clé not pour inverser un
    critère particulier. Notez que le mot not étant la
    négation d'une valeur, il ne peut pas être utilisé pour autoriser
    ou interdire une requête, car non vrai ne
    sera pas interpreté par httpd comme faux. Ainsi, pour interdire la
    visite d'une page à l'aide d'une négation, le bloc doit contenir un
    élément évalué à vrai ou faux.
    Par exemple, si quelqu'un est en train d'inonder
    votre forum de messages indésirables, vous pouvez ajouter cette ligne pour lui refuser
    l'accès :
    

    
    <RequireAll>
    Require all granted
    Require not ip 10.252.46.165
</RequireAll>
    


    
    Les visiteurs possédant cette adresse (10.252.46.165) ne pourront pas voir le
    contenu concerné par cette directive. Si vous voulez interdire
    l'accès à une machine en fonction de son nom, vous pouvez ajouter
    ceci :
    

    
    Require not host host.example.com
    
    


    
    Et si vous voulez interdire l'accès à un domaine particulier,
    vous pouvez spécifier des adresses IP partielles ou des noms de
    domaine, comme ceci :
    

    
    Require not ip 192.168.205
Require not host phishers.example.com moreidiots.example
Require not host gov
    


    
    Les directives RequireAll, RequireAny, et RequireNone permettent également de préciser des
    critères d'accès plus complexes.
    


    top
    

    

    Contrôle d'accès en fonction de variables
arbitraires
    

    
    Vous pouvez accorder ou refuser l'accès en fonction de variables
    d'environnement arbitraires ou de valeurs d'en-têtes de la requête
    en utilisant la directive <If>. Par exemple, pour interdire l'accès en
    fonction du user-agent (le type de navigateur), vous pouvez
    spécifier ceci :
    

    
    <If "%{HTTP_USER_AGENT} == 'BadBot'">
    Require all denied
</If>
    


    
    La syntaxe expr de la directive Require permet de réécrire
    l'exemple précédent de la manière suivante :
    


    
    Require expr %{HTTP_USER_AGENT} != 'BadBot'
    


    
    Avertissement :
    
    
    Contrôler l'accès en fonction de l'en-tête
    User-Agent n'est pas une technique fiable, car cet
    en-tête peut être défini à une valeur quelconque, selon le bon
    vouloir de l'utilisateur.
    
    
    

    
    Voir le document à propos des expressions pour une description plus
    approfondie des syntaxes d'expressions et des variables disponibles.
    


    top
    

    

    Utilisation de mod_rewrite pour le contrôle
d'accès
    

    
    Le drapeau [F] de la directive RewriteRule permet d'envoyer une
    réponse de type 403 Forbidden. Il vous permet donc d'interdire
    l'accès à une ressource en fonction d'un critère arbitraire.
    

    
    Par exemple, pour bloquer l'accès à une ressources entre 20h et
    7h du matin, vous pouvez utiliser mod_rewrite :
    

    
    RewriteEngine On
RewriteCond "%{TIME_HOUR}" ">=20" [OR]
RewriteCond "%{TIME_HOUR}" "<07"
RewriteRule "^/fridge"     "-" [F]
    


    
    Toute requête arrivant après 20h ou avant 7h du matin provoquera
    l'envoi d'une réponse de type 403 Forbidden. Vous pouvez utiliser
    cette technique pour vérifier toutes sortes de critères. En outre,
    si vous le préférez, vous pouvez rediriger ou réécrire la requête.
    

    
    Notez que la directive <If>, introduite à partir de la version 2.4,
    permet de remplacer le module mod_rewrite dans de
    nombreuses situations où il était traditionnellement utilisé, et
    il sera probablement préférable pour vous de tenter de l'utiliser
    avant de vous tourner vers mod_rewrite.
    


    top
    

    

    Informations complémentaires
    

    
    Le moteur d'expressions vous fournit
    une grande puissance d'action en fonction de variables du serveur
    arbitraires, et il vous est conseillé de consulter le document
    correspondant pour plus de détails.
    

    
    De même, vous devez lire la documentation du module

    Introduction
    
    

    
    Related ModulesRelated Directives
    

    
    The CGI (Common Gateway Interface) defines a way for a web
    server to interact with external content-generating programs,
    which are often referred to as CGI programs or CGI scripts. It
    is a simple way to put dynamic content on
    your web site, using whatever programming language you're most
    familiar with. This document will be an introduction to setting
    up CGI on your Apache web server, and getting started writing
    CGI programs.

    Configuring Apache to permit CGI
    
    

    
    In order to get your CGI programs to work properly, you'll
    need to have Apache configured to permit CGI execution. There
    are several ways to do this.
    

    
    Note: If Apache has been built with shared module
    support you need to ensure that the module is loaded; in your
    httpd.conf you need to make sure the
    LoadModule
    directive has not been commented out.  A correctly configured directive
    may look like this:

    
    LoadModule cgid_module modules/mod_cgid.so
    



     On Windows, or using a non-threaded MPM like prefork,  A correctly 
     configured directive may look like this:

    
    LoadModule cgi_module modules/mod_cgi.so
    

    


    
    ScriptAlias
    
      

      
    The
      ScriptAlias

      directive tells Apache that a particular directory is set
      aside for CGI programs. Apache will assume that every file in
      this directory is a CGI program, and will attempt to execute
      it, when that particular resource is requested by a
      client.
    

      
    The ScriptAlias
      directive looks like:
    

      
    ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/"
    


      
    The example shown is from your default httpd.conf
      configuration file, if you installed Apache in the default
      location. The ScriptAlias
      directive is much like the Alias directive, which defines a URL prefix that
      is to mapped to a particular directory. Alias
      and ScriptAlias are usually used for
      directories that are outside of the DocumentRoot directory. The difference between
      Alias and ScriptAlias
      is that ScriptAlias has the added meaning
      that everything under that URL prefix will be considered a CGI
      program. So, the example above tells Apache that any request for a
      resource beginning with /cgi-bin/ should be served from
      the directory  /usr/local/apache2/cgi-bin/, and should be
      treated as a CGI program.
    

      
    For example, if the URL
      http://www.example.com/cgi-bin/test.pl
      is requested, Apache will attempt to execute the file
      /usr/local/apache2/cgi-bin/test.pl
      and return the output. Of course, the file will have to
      exist, and be executable, and return output in a particular
      way, or Apache will return an error message.
    
    

    
    CGI outside of ScriptAlias directories
    
      

      
    CGI programs are often restricted to ScriptAlias'ed directories for security reasons.
      In this way, administrators can tightly control who is allowed to
      use CGI programs. However, if the proper security precautions are
      taken, there is no reason why CGI programs cannot be run from
      arbitrary directories. For example, you may wish to let users
      have web content in their home directories with the
      UserDir directive.
      If they want to have their own CGI programs, but don't have access to
      the main cgi-bin directory, they will need to be able to
      run CGI programs elsewhere.
    

      
    There are two steps to allowing CGI execution in an arbitrary
      directory.  First, the cgi-script handler must be
      activated using the AddHandler or SetHandler directive.  Second,
      ExecCGI must be specified in the Options directive.
    
    

    
    Explicitly using Options to permit CGI execution
    
      

      
    You could explicitly use the Options directive, inside your main server configuration
      file, to specify that CGI execution was permitted in a particular
      directory:
    

      
    <Directory "/usr/local/apache2/htdocs/somedir">
    Options +ExecCGI
</Directory>
    


      
    The above directive tells Apache to permit the execution
      of CGI files. You will also need to tell the server what
      files are CGI files. The following AddHandler directive tells the server to treat all
      files with the cgi or pl extension as CGI
      programs:
    

      
    AddHandler cgi-script .cgi .pl
    

    

    
    .htaccess files
    
      

      
    The .htaccess tutorial
      shows how to activate CGI programs if you do not have
      access to httpd.conf.
    
    

    
    User Directories
    
      

      
    To allow CGI program execution for any file ending in
      .cgi in users' directories, you can use the
      following configuration.
    

      
    <Directory "/home/*/public_html">
    Options +ExecCGI
    AddHandler cgi-script .cgi
</Directory>
    


      
    If you wish designate a cgi-bin subdirectory of
      a user's directory where everything will be treated as a CGI
      program, you can use the following.
    

      
    <Directory "/home/*/public_html/cgi-bin">
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    


    

  
    top
    

    

    Writing a CGI program
    
    

    
    There are two main differences between ``regular''
    programming, and CGI programming.
    

    
    First, all output from your CGI program must be preceded by
    a MIME-type header. This is HTTP header that tells the client
    what sort of content it is receiving. Most of the time, this
    will look like:
    

    
    
      Content-type: text/html
    
    

    
    Secondly, your output needs to be in HTML, or some other
    format that a browser will be able to display. Most of the
    time, this will be HTML, but occasionally you might write a CGI
    program that outputs a gif image, or other non-HTML
    content.
    

    
    Apart from those two things, writing a CGI program will look
    a lot like any other program that you might write.
    

    
    Your first CGI program
    
      

      
    The following is an example CGI program that prints one
      line to your browser. Type in the following, save it to a
      file called first.pl, and put it in your
      cgi-bin directory.
    

      
    #!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, World.";
    


      
    Even if you are not familiar with Perl, you should be able
      to see what is happening here. The first line tells Apache
      (or whatever shell you happen to be running under) that this
      program can be executed by feeding the file to the
      interpreter found at the location /usr/bin/perl.
      The second line prints the content-type declaration we
      talked about, followed by two carriage-return newline pairs.
      This puts a blank line after the header, to indicate the end
      of the HTTP headers, and the beginning of the body. The third
      line prints the string "Hello, World.". And that's the end
      of it.
    

      
    If you open your favorite browser and tell it to get the
      address
    

      
    
        http://www.example.com/cgi-bin/first.pl
      
    

      
    or wherever you put your file, you will see the one line
      Hello, World. appear in your browser window.
      It's not very exciting, but once you get that working, you'll
      have a good chance of getting just about anything working.
    
    
  
    top
    

    

    But it's still not working!
    
    

    
    There are four basic things that you may see in your browser
    when you try to access your CGI program from the web:
    

    
    
      
    The output of your CGI program
    
      
    Great! That means everything worked fine.  If the output is correct,
      but the browser is not processing it correctly, make sure you have the
      correct Content-Type set in your CGI program.
    

      
    The source code of your CGI program or a "POST Method Not
      Allowed" message
    
      
    That means that you have not properly configured Apache
      to process your CGI program. Reread the section on
      configuring
      Apache and try to find what you missed.
    

      
    A message starting with "Forbidden"
    
      
    That means that there is a permissions problem. Check the
      Apache error log and the section below on
      file permissions.
    

      
    A message saying "Internal Server Error"
    
      
    If you check the
      Apache error log, you will probably
      find that it says "Premature end of
      script headers", possibly along with an error message
      generated by your CGI program. In this case, you will want to
      check each of the below sections to see what might be
      preventing your CGI program from emitting the proper HTTP
      headers.
    
    
    

    
    File permissions
    
      

      
    Remember that the server does not run as you. That is,
      when the server starts up, it is running with the permissions
      of an unprivileged user - usually nobody, or
      www - and so it will need extra permissions to
      execute files that are owned by you. Usually, the way to give
      a file sufficient permissions to be executed by nobody
      is to give everyone execute permission on the file:
    

      
    
        chmod a+x first.pl
      
    

      
    Also, if your program reads from, or writes to, any other
      files, those files will need to have the correct permissions
      to permit this.
    

    

    
    Path information and environment
    
      

      
    When you run a program from your command line, you have
      certain information that is passed to the shell without you
      thinking about it. For example, you have a PATH,
      which tells the shell where it can look for files that you
      reference.
    

      
    When a program runs through the web server as a CGI program,
      it may not have the same PATH. Any programs that you
      invoke in your CGI program (like sendmail, for
      example) will need to be specified by a full path, so that the
      shell can find them when it attempts to execute your CGI
      program.
    

      
    A common manifestation of this is the path to the script
      interpreter (often perl) indicated in the first
      line of your CGI program, which will look something like:
    

      
    #!/usr/bin/perl
    


      
    Make sure that this is in fact the path to the
      interpreter.
    
      
    
      When editing CGI scripts on Windows, end-of-line characters may be
      appended to the interpreter path. Ensure that files are then
      transferred to the server in ASCII mode. Failure to do so may
      result in "Command not found" warnings from the OS, due to the
      unrecognized end-of-line character being interpreted as a part of
      the interpreter filename.
      
    
    

    
    Missing environment variables
    
      

      
    If your CGI program depends on non-standard environment variables, you will need to
      assure that those variables are passed by Apache.
    

      
    When you miss HTTP headers from the environment, make
      sure they are formatted according to
      RFC 2616,
      section 4.2: Header names must start with a letter,
      followed only by letters, numbers or hyphen. Any header
      violating this rule will be dropped silently.
    

    

    
    Program errors
    
      

      
    Most of the time when a CGI program fails, it's because of
      a problem with the program itself. This is particularly true
      once you get the hang of this CGI stuff, and no longer make
      the above two mistakes.  The first thing to do is to make
      sure that your program runs from the command line before
      testing it via the web server.  For example, try:
    

      
    
      cd /usr/local/apache2/cgi-bin
    
      ./first.pl
      
    

      
    (Do not call the perl interpreter.  The shell
      and Apache should find the interpreter using the path information on the first line of
      the script.)
    

      
    The first thing you see written by your program should be
      a set of HTTP headers, including the Content-Type,
      followed by a blank line.  If you see anything else, Apache will
      return the Premature end of script headers error if
      you try to run it through the server. See Writing a CGI program above for more
      details.
    
    

    
    Error logs
    
      

      
    The error logs are your friend. Anything that goes wrong
      generates message in the error log. You should always look
      there first. If the place where you are hosting your web site
      does not permit you access to the error log, you should
      probably host your site somewhere else. Learn to read the
      error logs, and you'll find that almost all of your problems
      are quickly identified, and quickly solved.
    
    

    
    Suexec
    
      

      
    The suexec support program
      allows CGI programs to be run under different user permissions,
      depending on which virtual host or user home directory they are
      located in. Suexec has very strict permission checking, and any
      failure in that checking will result in your CGI programs
      failing with Premature end of script headers.
    

      
    To check if you are using suexec, run apachectl
      -V and check for the location of SUEXEC_BIN.
      If Apache finds an suexec binary there on startup,
      suexec will be activated.
    

      
    Unless you fully understand suexec, you should not be using it.
      To disable suexec, simply remove (or rename) the suexec
      binary pointed to by SUEXEC_BIN and then restart the
      server.  If, after reading about suexec,
      you still wish to use it, then run suexec -V to find
      the location of the suexec log file, and use that log file to
      find what policy you are violating.
    
    
  
    top
    

    

    What's going on behind the scenes?
    
    

    
    As you become more advanced in CGI programming, it will
    become useful to understand more about what's happening behind
    the scenes. Specifically, how the browser and server
    communicate with one another. Because although it's all very
    well to write a program that prints "Hello, World.", it's not
    particularly useful.
    

    
    Environment variables
    
      

      
    Environment variables are values that float around you as
      you use your computer. They are useful things like your path
      (where the computer searches for the actual file
      implementing a command when you type it), your username, your
      terminal type, and so on. For a full list of your normal,
      every day environment variables, type
      env at a command prompt.
    

      
    During the CGI transaction, the server and the browser
      also set environment variables, so that they can communicate
      with one another. These are things like the browser type
      (Netscape, IE, Lynx), the server type (Apache, IIS, WebSite),
      the name of the CGI program that is being run, and so on.
    

      
    These variables are available to the CGI programmer, and
      are half of the story of the client-server communication. The
      complete list of required variables is at
      Common Gateway
      Interface RFC.
    

      
    This simple Perl CGI program will display all of the
      environment variables that are being passed around. Two
      similar programs are included in the
      cgi-bin

      directory of the Apache distribution. Note that some
      variables are required, while others are optional, so you may
      see some variables listed that were not in the official list.
      In addition, Apache provides many different ways for you to
      add your own environment variables
      to the basic ones provided by default.
    

      
    #!/usr/bin/perl
use strict;
use warnings;

print "Content-type: text/html\n\n";
foreach my $key (keys %ENV) {
    print "$key --> $ENV{$key}<br>";
}
    

    

    
    STDIN and STDOUT
    
      

      
    Other communication between the server and the client
      happens over standard input (STDIN) and standard
      output (STDOUT). In normal everyday context,
      STDIN means the keyboard, or a file that a
      program is given to act on, and STDOUT
      usually means the console or screen.
    

      
    When you POST a web form to a CGI program,
      the data in that form is bundled up into a special format
      and gets delivered to your CGI program over STDIN.
      The program then can process that data as though it was
      coming in from the keyboard, or from a file
    

      
    The "special format" is very simple. A field name and
      its value are joined together with an equals (=) sign, and
      pairs of values are joined together with an ampersand
      (&). Inconvenient characters like spaces, ampersands, and
      equals signs, are converted into their hex equivalent so that
      they don't gum up the works. The whole data string might look
      something like:
    

      
    
        name=Rich%20Bowen&city=Lexington&state=KY&sidekick=Squirrel%20Monkey
      
    

      
    You'll sometimes also see this type of string appended to
      a URL. When that is done, the server puts that string
      into the environment variable called
      QUERY_STRING. That's called a GET
      request. Your HTML form specifies whether a GET
      or a POST is used to deliver the data, by setting the
      METHOD attribute in the FORM tag.
    

      
    Your program is then responsible for splitting that string
      up into useful information. Fortunately, there are libraries
      and modules available to help you process this data, as well
      as handle other of the aspects of your CGI program.
    
    
  
    top
    

    

    CGI modules/libraries
    
    

    
    When you write CGI programs, you should consider using a
    code library, or module, to do most of the grunt work for you.
    This leads to fewer errors, and faster development.
    

    
    If you're writing CGI programs in Perl, modules are
    available on CPAN. The most
    popular module for this purpose is CGI.pm. You might
    also consider CGI::Lite, which implements a minimal
    set of functionality, which is all you need in most programs.
    

    
    If you're writing CGI programs in C, there are a variety of
    options. One of these is the CGIC library, from
    https://web.mit.edu/wwwdev/www/cgic.html.
    
  
    top
    

    

    For more information
    
    

    
    The current CGI specification is available in the
    Common Gateway
    Interface RFC.
    

    
    When you post a question about a CGI problem that you're
    having, whether to a mailing list, or to a newsgroup, make sure
    you provide enough information about what happened, what you
    expected to happen, and how what actually happened was
    different, what server you're running, what language your CGI
    program was in, and, if possible, the offending code. This will
    make finding your problem much simpler.
    

    
    Note that questions about CGI problems should never
    be posted to the Apache bug database unless you are sure you
    have found a problem in the Apache source code.

Reverse Proxy Guide - Apache HTTP Server Version 2.4

    In addition to being a "basic" web server, and providing static and
    dynamic content to end-users, Apache httpd (as well as most other web
    servers) can also act as a reverse proxy server, also-known-as a
    "gateway" server.
    

    
    In such scenarios, httpd itself does not generate or host the data,
    but rather the content is obtained by one or several backend servers,
    which normally have no direct connection to the external network. As
    httpd receives a request from a client, the request itself is proxied
    to one of these backend servers, which then handles the request, generates
    the content and then sends this content back to httpd, which then
    generates the actual HTTP response back to the client.
    

    
    There are numerous reasons for such an implementation, but generally
    the typical rationales are due to security, high-availability, load-balancing
    and centralized authentication/authorization. It is critical in these
    implementations that the layout, design and architecture of the backend
    infrastructure (those servers which actually handle the requests) are
    insulated and protected from the outside; as far as the client is concerned,
    the reverse proxy server is the sole source of all content.
    

    
    A typical implementation is below:
    
    
    reverse-proxy-arch

    Simple reverse proxying
    
    

    
    
      The ProxyPass
      directive specifies the mapping of incoming requests to the backend
      server (or a cluster of servers known as a Balancer
      group). The simplest example proxies all requests ("/")
      to a single backend:
    
    

    
    ProxyPass "/"  "http://www.example.com/"
    


    
    
      To ensure that and Location: headers generated from
      the backend are modified to point to the reverse proxy, instead of
      back to itself, the ProxyPassReverse
      directive is most often required:
    
    

    
    ProxyPass "/"  "http://www.example.com/"
ProxyPassReverse "/"  "http://www.example.com/"
    


    
    Only specific URIs can be proxied, as shown in this example:
    

    
    ProxyPass "/images"  "http://www.example.com/"
ProxyPassReverse "/images"  "http://www.example.com/"
    


    
    In the above, any requests which start with the /images
      path with be proxied to the specified backend, otherwise it will be handled
      locally.
    
    
  
    top
    

    

    Clusters and Balancers
    
    

    
    
      As useful as the above is, it still has the deficiencies that should
      the (single) backend node go down, or become heavily loaded, that proxying
      those requests provides no real advantage. What is needed is the ability
      to define a set or group of backend servers which can handle such
      requests and for the reverse proxy to load balance and failover among
      them. This group is sometimes called a cluster but Apache httpd's
      term is a balancer. One defines a balancer by leveraging the
      <Proxy> and
      BalancerMember directives as
      shown:
    
    

    
    <Proxy balancer://myset>
    BalancerMember http://www2.example.com:8080
    BalancerMember http://www3.example.com:8080
    ProxySet lbmethod=bytraffic
</Proxy>

ProxyPass "/images/"  "balancer://myset/"
ProxyPassReverse "/images/"  "balancer://myset/"
    


    
    
      The balancer:// scheme is what tells httpd that we are creating
      a balancer set, with the name myset. It includes 2 backend servers,
      which httpd calls BalancerMembers. In this case, any requests for
      /images will be proxied to one of the 2 backends.
      The ProxySet directive
      specifies that the myset Balancer use a load balancing algorithm
      that balances based on I/O bytes.
    
    

    
    Hint
    
      
    
      	BalancerMembers are also sometimes referred to as workers.
      
    
   
    

  
    top
    

    

    Balancer and BalancerMember configuration
    
    

    
    
      You can adjust numerous configuration details of the balancers
      and the workers via the various parameters defined in
      ProxyPass. For example,
      assuming we would want http://www3.example.com:8080 to
      handle 3x the traffic with a timeout of 1 second, we would adjust the
      configuration as follows:
    
    

    
    <Proxy balancer://myset>
    BalancerMember http://www2.example.com:8080
    BalancerMember http://www3.example.com:8080 loadfactor=3 timeout=1
    ProxySet lbmethod=bytraffic
</Proxy>

ProxyPass "/images"  "balancer://myset/"
ProxyPassReverse "/images"  "balancer://myset/"
    


  
    top
    

    

    Failover
    
    

    
    
      You can also fine-tune various failover scenarios, detailing which workers
      and even which balancers should be accessed in such cases. For example, the
      below setup implements three failover cases:
    
    
    
      
      
    1. 
        http://spare1.example.com:8080 and
        http://spare2.example.com:8080 are only sent traffic if one
        or both of http://www2.example.com:8080 or
        http://www3.example.com:8080 is unavailable. (One spare
        will be used to replace one unusable member of the same balancer set.)
      
      2. 
      
    2. 
        http://hstandby.example.com:8080 is only sent traffic if
        all other workers in balancer set 0 are not available.
      
      3. 
      
    3. 
        If all load balancer set 0 workers, spares, and the standby
        are unavailable, only then will the
        http://bkup1.example.com:8080 and
        http://bkup2.example.com:8080 workers from balancer set
        1 be brought into rotation.
      
      4. 
    
    
    
    
      Thus, it is possible to have one or more hot spares and hot standbys for
      each load balancer set.
    
    

    
    <Proxy balancer://myset>
    BalancerMember http://www2.example.com:8080
    BalancerMember http://www3.example.com:8080 loadfactor=3 timeout=1
    BalancerMember http://spare1.example.com:8080 status=+R
    BalancerMember http://spare2.example.com:8080 status=+R
    BalancerMember http://hstandby.example.com:8080 status=+H
    BalancerMember http://bkup1.example.com:8080 lbset=1
    BalancerMember http://bkup2.example.com:8080 lbset=1
    ProxySet lbmethod=byrequests
</Proxy>

ProxyPass "/images/"  "balancer://myset/"
ProxyPassReverse "/images/"  "balancer://myset/"
    


    
    
      For failover, hot spares are used as replacements for unusable workers in
      the same load balancer set. A worker is considered unusable if it is
      draining, stopped, or otherwise in an error/failed state. Hot standbys are
      used if all workers and spares in the load balancer set are
      unavailable. Load balancer sets (with their respective hot spares and
      standbys) are always tried in order from lowest to highest.

    Balancer Manager
    
    

    
    
      One of the most unique and useful features of Apache httpd's reverse proxy is
	  the embedded balancer-manager application. Similar to
	  mod_status, balancer-manager displays
	  the current working configuration and status of the enabled
	  balancers and workers currently in use. However, not only does it
	  display these parameters, it also allows for dynamic, runtime, on-the-fly
	  reconfiguration of almost all of them, including adding new BalancerMembers
	  (workers) to an existing balancer. To enable these capability, the following
	  needs to be added to your configuration:
    
    

    
    <Location "/balancer-manager">
    SetHandler balancer-manager
    Require host localhost
</Location>
    


    
    Warning
    
      
    Do not enable the balancer-manager until you have secured your server. In
      particular, ensure that access to the URL is tightly
      restricted.
    
    
    

    
    
      When the reverse proxy server is accessed at that url
      (eg: http://rproxy.example.com/balancer-manager/, you will see a
      page similar to the below:
    
    
    
    balancer-manager page
    

    
    
      This form allows the devops admin to adjust various parameters, take
      workers offline, change load balancing methods and add new works. For
      example, clicking on the balancer itself, you will get the following page:
    
    
    
    balancer-manager page
    

    
    
      Whereas clicking on a worker, displays this page:
    
    
    
    balancer-manager page
    

    
    
      To have these changes persist restarts of the reverse proxy, ensure that
      BalancerPersist is enabled.

    Dynamic Health Checks
    
    

    
    
      Before httpd proxies a request to a worker, it can "test" if that worker
      is available via setting the ping parameter for that worker using
      ProxyPass. Oftentimes it is
      more useful to check the health of the workers out of band, in a
      dynamic fashion. This is achieved in Apache httpd by the
      mod_proxy_hcheck module.
    
    

  
    top
    

    

    BalancerMember status flags
    
    

    
    
      In the balancer-manager the current state, or status, of a worker
      is displayed and can be set/reset. The meanings of these statuses are as follows:
    
    
      
    
      	
    FlagStringDescription
    
      	
     OkWorker is available
    
      	
     InitWorker has been initialized
    
        
    DDisWorker is disabled and will not accept any requests; will be
                    automatically retried.
    
        
    SStopWorker is administratively stopped; will not accept requests
                    and will not be automatically retried
    
        
    IIgnWorker is in ignore-errors mode and will always be considered available.
    
        
    RSparWorker is a hot spare. For each worker in a given lbset that is unusable
                    (draining, stopped, in error, etc.), a usable hot spare with the same lbset will be used in
                    its place. Hot spares can help ensure that a specific number of workers are always available
                    for use by a balancer.
    
        
    HStbyWorker is in hot-standby mode and will only be used if no other
                    viable workers or spares are available in the balancer set.
    
        
    EErrWorker is in an error state, usually due to failing pre-request check;
                    requests will not be proxied to this worker, but it will be retried depending on
                    the retry setting of the worker.
    
        
    NDrnWorker is in drain mode and will only accept existing sticky sessions
                    destined for itself and ignore all other requests.
    
        
    CHcFlWorker has failed dynamic health check and will not be used until it
                    passes subsequent health checks.

    Introduction
    
    

    
    Modules ApparentésDirectives Apparentées
    

    
    CGI (Common Gateway Interface) définit une méthode d'interaction
    entre un serveur web et des programmes générateurs de contenu
    externes, plus souvent appelés programmes CGI ou scripts CGI.
    Il s'agit d'une méthode simple pour ajouter du contenu dynamique à votre site
    web en utilisant votre langage de programmation préféré.
    Ce document est une introduction à la configuration de CGI sur votre
    serveur web Apache, et une initiation à l'écriture de programmes
    CGI.
    
  
    top
    

    

    Configurer Apache pour autoriser CGI
    
    

    
    Apache doit être configuré pour permettre l'exécution des
    programmes CGI, pour que vos programmes CGI puissent fonctionner
    correctement. Il existe plusieurs méthodes pour y parvenir.
    

    
    Note: si Apache a été compilé avec le support
    des modules partagés (DSO), vous devez vous assurer que le module CGI est
    chargé ; vous devez pour cela vérifier que la directive LoadModule correspondante n'a pas été
    commentée dans votre httpd.conf. Une directive correcte
    doit ressembler à ceci :

    
    LoadModule cgid_module modules/mod_cgid.so
    



     Sous Windows, ou si l'on utilise un module MPM non-threadé comme prefork,
     une directive correctement configurée sera du style :

    
    LoadModule cgi_module modules/mod_cgi.so
    

    


    
    ScriptAlias
    
      

      
    La directive ScriptAlias indique à Apache qu'un
      répertoire particulier est dédié aux programmes CGI. Apache
      considérera que tout fichier situé dans ce répertoire est un
      programme CGI, et tentera de l'exécuter lorsque cette ressource
      fera l'objet d'une requête client.
    

      
    La directive ScriptAlias se présente comme suit
      :
    

      
    ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/"
    


      
    Cet exemple est tiré de votre fichier de configuration
      httpd.conf par défaut, si vous avez installé Apache
      dans son répertoire par défaut. La directive ScriptAlias est similaire à la
      directive Alias, qui
      définit à quel répertoire particulier doit correspondre un préfixe
      d'URL. Alias et
      ScriptAlias sont généralement utilisés pour
      accéder à des répertoires situés en dehors du répertoire défini
      par la directive DocumentRoot. La différence entre
      Alias et ScriptAlias
      réside dans le fait que ScriptAlias indique
      en plus que tout ce qui se trouve sous le préfixe d'URL doit être
      considéré comme un programme CGI. Ainsi, l'exemple ci-dessus
      indique à Apache que toute requête pour une ressource commençant
      par /cgi-bin/ doit être servie depuis le répertoire
      /usr/local/apache2/cgi-bin/, et doit être traitée en
      tant que programme CGI.
    

      
    Par exemple, si une requête pour l'URL
      http://www.example.com/cgi-bin/test.pl est
      effectuée, Apache tentera d'exécuter le fichier
      /usr/local/apache2/cgi-bin/test.pl et en renverra la
      sortie. Bien entendu, le fichier doit exister, être exécutable, et
      retourner sa sortie d'une manière particulière, sinon Apache
      renverra un message d'erreur.
    
    

    
    CGI en dehors des répertoires ScripAlias
    
      

      
    Pour des raisons de sécurité, la localisation des programmes
      CGI est souvent restreinte aux
      répertoires définis par ScriptAlias. De cette manière, les administrateurs
      peuvent contrôler précisément qui est autorisé à utiliser les
      programmes CGI. Cependant, si les précautions adéquates quant à
      la sécurité sont prises, il n'y a aucune raison pour que les
      programmes CGI ne puissent pas être exécutés depuis d'autres
      répertoires. Par exemple, vous pouvez autoriser les utilisateurs à
      enregistrer des contenus web dans leurs répertoires home à l'aide
      de la directive UserDir. S'ils veulent mettre en
      oeuvre leurs propres programmes CGI, mais n'ont pas l'autorisation
      d'accès au répertoire cgi-bin principal, ils devront
      être en mesure d'exécuter ces programmes depuis un autre
      répertoire.
    

      
    L'autorisation d'exécution des programmes CGI dans un
      répertoire arbitraire se fait en deux étapes. En premier lieu, le
      gestionnaire cgi-script doit être activé à l'aide
      d'une directive AddHandler ou SetHandler. En second lieu,
      ExecCGI doit être spécifié dans la directive Options.
    
    

    
    Utilisation d'options explicites pour permettre l'exécution
      des programmes CGI
    
      

      
    Vous pouvez utiliser de manière explicite la directive
      Options dans le fichier de
      configuration de votre serveur principal, pour indiquer que
      l'exécution des programmes CGI est permise depuis un répertoire
      particulier :
    

      
    <Directory "/usr/local/apache2/htdocs/somedir">
    Options +ExecCGI
</Directory>
    


      
    La directive ci-dessus indique à Apache qu'il doit permettre
      l'exécution des fichiers CGI. Vous devez aussi indiquer au serveur
      quels fichiers sont des fichiers CGI. La directive AddHandler suivante indique au
      serveur qu'il doit traiter tous les fichiers possédant une
      extension cgi ou pl en tant que
      programmes CGI :
    

      
    AddHandler cgi-script .cgi .pl
    

    

    
    Fichiers .htaccess
    
      

      
    Le tutoriel
      .htaccess montre comment activer les programmes
      CGI si vous n'avez pas accès au
      fichier httpd.conf.
    
    

    
    Répertoires utilisateurs
    
      

      
    Pour permettre l'exécution en tant que programme CGI de tout
      fichier possédant l'extension .cgi et situé dans un
      répertoire utilisateur, vous pouvez utiliser la configuration
      suivante :
    

      
    <Directory "/home/*/public_html">
    Options +ExecCGI
    AddHandler cgi-script .cgi
</Directory>
    


      
    Pour indiquer un sous-répertoire cgi-bin d'un
      répertoire utilisateur où tout fichier sera traité en tant que
      programme CGI, vous pouvez utiliser ceci :
    

      
    <Directory "/home/*/public_html/cgi-bin">
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    


    

  
    top
    

    

    Ecrire un programme CGI
    
    

    
    Il y a deux différences principales entre la programmation
    "standard" et la programmation CGI.
    

    
    En premier lieu, toute sortie de votre programme CGI doit être
    précédée d'un en-tête MIME-type. Il s'agit d'un
    en-tête HTTP qui indique au client quel type de contenu il reçoit.
    La plupart du temps, il se présente comme suit :
    

    
    
      Content-type: text/html
    
    

    
    En second lieu, votre sortie doit être en HTML, ou tout autre
    format qu'un navigateur est en mesure d'afficher. La plupart du
    temps, il s'agira de HTML, mais occasionnellement, vous pouvez être
    amené à écrire un programme CGI qui renvoie une image gif, ou un
    autre type de contenu non-HTML.
    

    
    A part ces deux différences, un programme CGI ressemblera à tout
    autre programme que vous pourriez être amené à écrire.
    

    
    Votre premier programme CGI
    
      

      
    L'exemple suivant est un exemple de programme CGI qui permet
      d'afficher une ligne de caractères dans votre navigateur. Ecrivez
      ce qui suit, enregistrez le dans un fichier nommé
      premier.pl, et placez le dans votre répertoire
      cgi-bin.
    

      
    #!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hello, World.";
    


      
    Même si Perl ne vous est pas familier, vous devriez être
      capable de comprendre le fonctionnement de ce programme. La
      première ligne indique à Apache (ou à toute interface à partir de
      laquelle le programme s'exécute) que ce programme peut être
      exécuté en fournissant son fichier à l'interpréteur
      /usr/bin/perl. La seconde ligne affiche la
      déclaration du type de contenu considéré, suivie de deux paires
      "Retour chariot - Nouvelle ligne". Ceci a pour effet d'insérer une
      ligne vide après l'en-tête pour marquer la fin des en-têtes HTTP,
      et le début du corps du document. La troisième ligne affiche la
      chaîne de caractères "Bonjour tout le monde . . .". Et c'est tout
      ce dont vous avez besoin.
    

      
    Si vous ouvrez votre navigateur favori et lui indiquez
      l'adresse
    

      
    
        http://www.example.com/cgi-bin/premier.pl
      
    

      
    ou toute autre URL correspondant à votre programme CGI, Vous
      verrez la ligne Bonjour tout le monde . . .
      s'afficher dans la fenêtre de votre navigateur. Ce n'est pas
      extraordinaire, mais si vous y êtes parvenu, vous avez de bonnes
      chances d'y parvenir pour tout autre programme plus
      sophistiqué.
    
    
  
    top
    

    

    Mais ça ne marche toujours pas !
    
    

    
    Vous devriez voir au moins une des quatre sorties suivantes dans
    votre navigateur lorsque vous essayez d'accéder à votre programme
    CGI depuis le web :
    

    
    
      
    Le flux de sortie de votre programme CGI
    
      
    Impeccable ! Cela signifie que tout fonctionne correctement.
      Si la sortie est correcte mais n'est pas traitée correctement par
      le navigateur, assurez-vous d'avoir défini
      Content-Type de manière appropriée dans votre
      programme CGI.
    

      
    Le code source de votre programme CGI ou un message "POST
      Method Not Allowed"
    
      
    Cela signifie que vous n'avez pas configuré Apache de manière
      à ce qu'il puisse traiter votre programme CGI. Relisez la section
      sur la configuration d'Apache, et
      essayez de trouver votre erreur.
    

      
    Un message commençant par "Forbidden"
    
      
    Ce type de message est révélateur d'un problème de
      droits. Consultez le journal des erreurs
      d'Apache et la section ci-dessous sur les droits des fichiers.
    

      
    Un message contenant "Internal Server Error"
    
      
    Si vous consultez le journal des erreurs
      d'Apache, vous y trouverez probablement des messages du type
      "Premature end of script headers" (Fin prématurée des en-têtes de
      script), éventuellement accompagnés d'un message d'erreur généré
      par votre programme CGI. Dans ce cas, il va vous falloir lire
      chacune des sections ci-dessous pour déterminer ce qui empêche
      votre programme CGI de générer les en-têtes appropriés.
    
    
    

    
    Droits des fichiers
    
      

      
    Souvenez-vous que le serveur ne s'exécute pas sous votre nom.
      En d'autres termes, lorsque le serveur a démarré, il s'exécute
      avec les droits d'un utilisateur non privilégié - en général
      nobody, ou www - et en conséquence, il
      aura besoin de droits supplémentaires pour pouvoir exécuter des
      fichiers dont vous êtes le propriétaire. En général, pour qu'un
      fichier ait des droits suffisants pour être exécutable par
      nobody, il suffit de lui attribuer des droits
      d'exécution pour tout le monde :
    

      
    
        chmod a+x premier.pl
      
    

      
    En outre, si votre programme doit pouvoir accéder en lecture
      et/ou écriture à d'autres fichiers, ces derniers devront avoir les
      droits appropriés.
    

    

    
    Chemin des exécutables (PATH) et variables
      d'environnement
    
      

      
    Lorsque vous lancez un programme depuis la ligne de commande,
      certaines informations sont passées au shell sans que vous vous en
      doutiez. Par exemple, la variable PATH indique au
      shell où il doit rechercher les exécutables auxquels vous faites
      référence.
    

      
    Lorsqu'un programme s'exécute depuis le serveur web en tant que
      programme CGI, sa variable PATH n'aura peut-être pas
      la même valeur. Tout programme que vous invoquez dans votre
      programme CGI ( comme par exemple sendmail) devra
      être spécifié par son chemin complet, de façon à ce que le shell
      puisse le trouver lorsqu'il tentera d'exécuter votre programme
      CGI.
    

      
    Un exemple typique de spécification de programme est le chemin
      vers l'interpréteur de script (souvent perl) que l'on
      trouve à la première ligne de votre programme CGI et qui va
      ressembler à ceci :
    

      
    #!/usr/bin/perl
    


      
    Assurez-vous qu'il s'agit bien du chemin correct vers
      l'interpréteur.
    

      
    
      Lors de l'édition de scripts CGI sous Windows, il se peut que des
      caractères de fin de ligne soient ajoutés au chemin de
      l'interpréteur. Assurez-vous donc que les fichiers sont bien
      transmis au serveur en mode ASCII. Dans le cas contraire, l'OS
      pourra envoyer des avertissements "Command not found" à cause des
      caractères de fin de ligne non reconnus car considérés comme
      faisant partie du nom de fichier de l'interpréteur.
      
    

      

    
    Variables d'environnement manquantes
    
      

      
    Si votre programme CGI dépend de variables
      d'environnement non standards, vous devrez vous assurez que
      ces variables lui sont bien transmises par Apache.
    

      
    Lorsque des en-têtes HTTP ne sont pas transmis à
      l'environnement, assurez-vous qu'ils sont bien formatés selon la
      RFC 2616, section
      4.2 : les noms d'en-têtes doivent commencer par une lettre,
      elle-même suivie de lettres, chiffres ou traits d'union. Tout
      en-tête dont le nom viole cette règle sera ignoré.
    

    

    
    Erreurs inhérentes au programme
    
      

      
    La plupart des échecs dans l'exécution d'un programme CGI
      proviennent du programme lui-même. Ceci est particulièrement vrai
      lorsque ce satané programme CGI se bloque, alors que vous avez
      appris à ne plus commettre les deux erreurs précédentes. La
      première chose à faire est de vous assurer que votre programme
      s'exécute depuis la ligne de commande, avant de le tester à partir
      du serveur web. Par exemple, essayez :
    

      
    
      cd /usr/local/apache2/cgi-bin
    
      ./premier.pl
      
    

      
    (N'invoquez pas l'interpréteur perl. Le shell et
      Apache doivent être capable de le déterminer à partir de l'information sur le chemin située sur
      la première ligne du script.)
    

      
    La première chose que vous devriez voir affichée par votre
      programme est un ensemble d'en-têtes HTTP, comprenant entre autres
      le Content-Type, et suivi d'une ligne vide. Si vous
      voyez quoi que ce soit d'autre, Apache renverra l'erreur
      Premature end of script headers si vous tentez
      d'exécuter le programme depuis le serveur. Voir Ecriture d'un programme CGI ci-dessus pour
      plus de détails.
    
    

    
    Journalisation des erreurs
    
      

      
    Les journaux d'erreurs sont vos amis. Toute anomalie de
      fonctionnement est consignée dans le journal des erreurs et c'est
      ici que vous devez regarder en premier en cas de problème. Si
      l'hébergeur de votre site ne vous donne pas accès au journal des
      erreurs, vous avez tout intérêt à vous tourner vers quelqu'un
      d'autre. Apprenez à déchiffrer les journaux d'erreurs, et vous
      vous apercevrez que la plupart des problèmes seront rapidement
      identifiés . . . et résolus.
    
    

    
    Suexec
    
      

      
    Le programme suexec permet
      d'exécuter les programmes CGI avec des droits différents selon le
      serveur virtuel ou le répertoire utilisateur dans lequel ils
      se situent. Suexec effectue une vérification des droits très
      stricte, et toute anomalie détectée au cours de cette vérification
      entraînera un echec d'exécution de votre programme CGI avec
      affichage de l'erreur Premature end of script
      headers.
    

      
    Pour savoir si vous pouvez utiliser suexec, tapez la commande
      apachectl -V, et regardez le chemin indiqué par
      SUEXEC_BIN. Si au démarrage d'Apache, ce dernier
      trouve un exécutable suexec dans ce chemin,
      suexec sera activé.
    

      
    Si vous ne maîtrisez pas le fonctionnement de suexec, il vous
      est déconseillé de l'utiliser. Pour désactiver suexec, supprimer
      simplement (ou renommez) l'exécutable suexec
      pointé par SUEXEC_BIN et redémarrez le serveur. Si
      après une lecture de suexec, vous
      décidez quand-même de l'utiliser, tapez la commande suexec
      -V pour voir où se situe le journal de suexec, et utilisez
      ce dernier pour déterminer quelles règles vous violez
      éventuellement.
    
    
  
    top
    

    

    Que se passe-t-il en coulisse
    
    

    
    Lorsque vos compétences en programmation CGI seront plus
    poussées, il s'avérera intéressant pour vous de mieux comprendre ce
    qui se passe en coulisse, et en particulier la manière dont le
    navigateur et le serveur dialoguent entre eux. En effet, bien qu'il
    soit tout à fait louable d'écrire un programme qui affiche "Bonjour
    tout le monde . . .", cela ne sert pas à grand chose.
    

    
    Variables d'environnement
    
      

      
    Les variables d'environnement sont des valeurs qui gravitent
      autour de vous lorsque vous utilisez votre ordinateur. Elles sont
      très utiles, à l'instar de votre chemin par défaut (où votre
      ordinateur va rechercher le fichier physique correspondant à la
      commande que vous avez tapée), votre nom d'utilisateur, le type de
      votre terminal, etc... Pour obtenir une liste complète des
      variables d'environnement standards que vous utilisez tous les
      jours, tapez env dans votre interpréteur
      de commandes.
    

      
    Au cours de la transaction CGI, le serveur et le navigateur
      définissent aussi des variables d'environnement, de façon à ce
      qu'ils puissent communiquer entre eux. Ces variables définissent
      entre autre le type de navigateur (Netscape, IE, Lynx), le type de
      serveur (Apache, IIS, WebSite), le nom du programme CGI en cours
      d'exécution, etc...
    

      
    Ces variables sont à la disposition du programmeur CGI, et
      elles constituent 50% de la communication client-serveur. La liste
      complète des variables requises se trouve à
      Common Gateway
      Interface RFC.
    

      
    Ce programme CGI basique en Perl permet d'afficher toutes les
      variables d'environnement qui sont échangées. Deux programmes
      similaires sont fournis avec la distribution d'Apache et situés
      dans le répertoire cgi-bin.
      Notez que certaines variables sont
      obligatoires, alors que d'autres sont optionnelles, si bien que
      vous verrez s'afficher certaines variables qui ne font pas partie
      de la liste officielle. De plus, Apache vous propose de nombreuses
      méthodes pour ajouter vos propres
      variables d'environnement aux variables de base fournies par
      défaut.
    

      
    #!/usr/bin/perl
use strict;
use warnings;

print "Content-type: text/html\n\n";
foreach my $key (keys %ENV) {
    print "$key --> $ENV{$key}<br>";
}
    

    

    
    STDIN et STDOUT
    
      

      
    L'entrée standard (STDIN) et la sortie standard
      (STDOUT) constituent d'autres voies de communication
      entre le client et le serveur. Dans un contexte normal,
      STDIN correspond au clavier, ou à un fichier fourni
      au programme à des fins de traitement, et STDOUT à la
      console ou à l'écran.
    

      
    Lorsque vous transmettez un formulaire web à un programme CGI
      par la méthode POST, les données de ce formulaire
      sont transcrites dans un format spécial et transmises à votre
      programme CGI via STDIN. Le programme peut alors les
      traiter comme si elles provenaient du clavier ou d'un
      fichier.
    

      
    Ce "format spécial" est très simple. Un nom de champ et sa
      valeur sont reliés entre eux par un signe "égal" (=), et chacune
      de ces paires nom champ/valeur est séparée de la suivante par un
      "et" commercial (&). Les caractères
      spéciaux comme les espaces, les "et" commerciaux, et les signes
      "égal" sont convertis en leur équivalent hexadécimal pour éviter
      qu'ils ne gâchent le travail. La chaîne contenant les données doit
      ressembler à ceci :
    

      
    
        name=Rich%20Bowen&city=Lexington&state=KY&sidekick=Squirrel%20Monkey
      
    

      
    Vous verrez aussi parfois une chaîne de ce type accolée à une
      URL. Dans ce cas, le serveur enregistre cette chaîne dans la
      variable d'environnement appelée QUERY_STRING. On a
      alors affaire à une requête de type GET. Votre
      formulaire HTML indique laquelle des méthodes GET ou
      POST est utilisée pour transmettre les données, en
      définissant l'attribut METHOD au niveau de la balise
      FORM.
    

      
    Votre programme est ensuite chargé d'extraire les informations
      utiles de cette chaîne. Heureusement, des bibliothèques et des
      modules sont à votre disposition pour vous aider à traiter ces
      données, et à gérer les différents aspects de votre programme
      CGI.

    Bibliothèques et modules CGI
    
    

    
    Pour écrire un programme CGI, il vous est conseillé d'utiliser
    une bibliothèque de code, ou un module, qui effectueront une grande
    partie du travail de base pour vous. Ceci vous permettra de diminuer
    le nombre d'erreurs et d'accélérer le développement.
    

    
    Si vous écrivez des programmes CGI en Perl, des modules sont à
    votre disposition à CPAN. A ce
    sujet, le module le plus populaire est CGI.pm. Vous
    pouvez aussi essayer CGI::Lite, qui implémente les
    fonctionnalités strictement nécessaires, mais suffisantes pour
    la majorité des programmes.
    

    
    Si vous écrivez des programmes CGI en C, vous disposez de nombreuses
    options. L'une d'elles est la bibliothèque CGIC de  https://web.mit.edu/wwwdev/www/cgic.html.
    
  
    top
    

    

    Pour plus d'informations
    
    

    
    La spécification CGI actuelle est disponible dans la Common Gateway
    Interface RFC.
    

    
    Lorsque vous postez une question à propos d'un problème CGI que
    vous rencontrez, que ce soit dans une liste de diffusion ou dans un
    newsgroup, faites en sorte de fournir suffisamment d'informations
    sur le problème rencontré, ce que vous attendiez exactement, et en
    quoi ce qui se produit est réellement différent de ce que vous
    attendiez, quel serveur vous utilisez, en quel langage votre
    programme CGI a été écrit, et, si possible, son code source. Ceci
    permettra une résolution plus aisée de votre problème.
    

    
    Notez que les questions à propos de problèmes CGI ne doivent
    jamais être postées dans la base de données de
    bogues d'Apache, à moins que vous ne soyez sûr d'avoir trouvé un
    problème dans le code source d'Apache.

    Guide de configuration d'un mandataire inverse
    

    

    Langues Disponibles:  en  |
 fr 
    

    

    
    En plus de ses fonctions de serveur web "basique", à savoir fournir du
    contenu statique et dynamique à l'utilisateur, Apache httpd (comme la
    plupart des autres serveurs web) peut aussi assurer les fonctions de serveur
    mandataire inverse, connu aussi sous le nom de serveur "passerelle".
    

    
    Dans un tel scénario, httpd ne génère et n'héberge pas lui-même les
    données, le contenu étant en général obtenu à partir d'un ou plusieurs serveurs
    d'arrière-plan qui n'ont normalement aucune connexion directe avec le réseau
    externe. Lorsque httpd reçoit une requête en provenance d'un client, la
    requête proprement dite est mandatée vers un de ces serveurs
    d'arrière-plan qui traite la requête, génère le contenu et l'envoie à httpd,
    ce dernier générant la véritable réponse HTTP à destination du client.
    

    
    De nombreuses raisons peuvent vous motiver à utiliser cette
    fonctionnalité, mais elles sont souvent du domaine de la sécurité, de
    la haute disponibilité, de la répartition de charge et de
    l'authentification/autorisation centralisée. Il est alors indispensable que
    l'organisation, la conception et l'architecture de l'infrastructure
    d'arrière-plan (les serveurs qui traitent au sens propre les requêtes) soient
    isolées et protégées de l'extérieur ; vu du client, le serveur mandataire
    inverse est le seul serveur accessible pouvant lui fournir du
    contenu.
    

    
    Voici un exemple typique d'implémentation de cette fonctionnalité :
    
    
    reverse-proxy-arch

    Mandataire inverse
    
  
  
    Modules ApparentésDirectives Apparentées
    
  
    top
    

    

    Mandatement inverse simple
    
    

    
    
      La directive ProxyPass permet de
      rediriger les requêtes entrantes vers un serveur d'arrière-plan (ou un
      cluster de serveurs plus connu sous le nom de groupe
      Balancer). Dans cet exemple le plus simple, toutes les
      requêtes ("/") sont redirigées vers un serveur d'arrière-plan
      unique :
    
    

    
    ProxyPass "/"  "http://www.example.com/"
    


    
    
      Pour être sur que cette redirection soit effectuée et que les en-têtes
      Location: générés par le serveur d'arrière-plan soient
      modifiés pour pointer vers le mandataire inverse, et non vers le serveur
      d'arrière-plan, la directive ProxyPassReverse est souvent requise :
    
    

    
    ProxyPass "/"  "http://www.example.com/"
ProxyPassReverse "/"  "http://www.example.com/"
    


    
    Seules des URIs spécifiques peuvent être mandatées, comme le montre
    l'exemple suivant :
    

    
    ProxyPass "/images"  "http://www.example.com/"
ProxyPassReverse "/images"  "http://www.example.com/"
    


    
    Dans l'exemple précédent, si le chemin d'une requête commence par
    /images, elle sera redirigée vers le serveur d'arrière-plan
    spécifié ; dans le cas contraire, elle sera traitée localement.
    
    
  
    top
    

    

    Clusters et Balancers
    
    

    
    
      Utiliser un serveur d'arrière-plan unique n'est cependant pas une solution
      idéale car ce dernier peut devenir indisponible ou surchargé, et le
      mandatement inverse vers ce serveur ne présente alors plus aucun avantage.
      La solution réside dans la définition d'un groupe de serveurs
      d'arrière-plan qui vont se partager le traitement des requêtes via un
      mécanisme de répartition de charge et de gestion des indisponibilités pris
      en charge par le mandataire. Ce groupe de répartition est plus connu sous le nom de
      cluster, mais dans la terminologie d'Apache httpd, on utilise
      plutôt le terme de balancer. Un balancer se définit en
      utilisant les directives <Proxy> et BalancerMember comme suit :
    
    

    
    <Proxy balancer://myset>
    BalancerMember http://www2.example.com:8080
    BalancerMember http://www3.example.com:8080
    ProxySet lbmethod=bytraffic
</Proxy>

ProxyPass "/images/"  "balancer://myset/"
ProxyPassReverse "/images/"  "balancer://myset/"
    


    
    
      Le protocole balancer:// indique à httpd que l'on souhaite
      créer un balancer nommé myset. Ce balancer comporte deux serveurs
      d'arrière-plan référencés dans la terminologie httpd sous le nom de
      BalancerMembers. Avec cet exemple, toute requête dont le chemin
      commence par /images sera mandatée vers un des deux
      serveurs d'arrière-plan. La directive ProxySet définit ici pour le balancer
      myset un algorithme de
      répartition de charge basé sur le trafic entrées/sorties.
    
    

    
    Remarque
    
      
    
      	Les BalancerMembers sont aussi souvent référencés sous le terme
	workers.
      
    
   
    

  
    top
    

    

    Configuration du Balancer et des BalancerMembers
    
    

    
    
      Vous pouvez configurer de manière détaillée les balancers et
      workers via les nombreux paramètres de la directive ProxyPass. Par exemple, si vous souhaitez
      que http://www3.example.com:8080 traite avec un facteur 3 le
      trafic avec un timeout d'une seconde, utilisez la configuration suivante :
    
    

    
    <Proxy balancer://myset>
    BalancerMember http://www2.example.com:8080
    BalancerMember http://www3.example.com:8080 loadfactor=3 timeout=1
    ProxySet lbmethod=bytraffic
</Proxy>

ProxyPass "/images"  "balancer://myset/"
ProxyPassReverse "/images"  "balancer://myset/"
    


  
    top
    

    

    Gestion des indisponibilités (Failover)
    
    

    
    
      Vous pouvez aussi définir finement des scénarios pour les cas
      d'indisponibilité d'un ou plusieurs serveurs d'arrière-plan en spécifiant
      quels serveurs doivent alors prendre le relai. Dans l'exemple suivant,
      trois scénarios sont envisagés :
    
    
    
      
      
    1. 
        http://spare1.example.com:8080 et
        http://spare2.example.com:8080 ne sont sollicités que si
	http://www2.example.com:8080 ou
	http://www3.example.com:8080 est indisponible (un serveur
	de remplacement sera utilisé à la place d'un membre indisponible du même
	jeu de serveurs cibles).
      
      2. 
      
    2. 
        http://hstandby.example.com:8080 n'est sollicité que si
	tous les autres serveurs cibles du jeu de serveurs 0 sont
	indisponibles.
      
      3. 
      
    3. 
        Les serveurs http://bkup1.example.com:8080 et
	http://bkup2.example.com:8080 du jeu 1 ne seront sollicités que si
	tous les serveurs du jeu 0, tous les serveurs de
	remplacement et tous les serveurs de standby sont indisponibles.
      
      4. 
    
    
    
    
      Il est ainsi possible de définir un ou plusieurs serveurs de remplacement
      ou de standby pour chaque jeu de serveurs du répartiteur de charge.
    
    

    
    <Proxy balancer://myset>
    BalancerMember http://www2.example.com:8080
    BalancerMember http://www3.example.com:8080 loadfactor=3 timeout=1
    BalancerMember http://spare1.example.com:8080 status=+R
    BalancerMember http://spare2.example.com:8080 status=+R
    BalancerMember http://hstandby.example.com:8080 status=+H
    BalancerMember http://bkup1.example.com:8080 lbset=1
    BalancerMember http://bkup2.example.com:8080 lbset=1
    ProxySet lbmethod=byrequests
</Proxy>

ProxyPass "/images/"  "balancer://myset/"
ProxyPassReverse "/images/"  "balancer://myset/"
    


    
    
      Les serveurs de remplacement à chaud remplacent les serveurs indisponibles
      du même jeu de serveurs du répartiteur de charge. Un serveur est
      considéré comme indisponible s'il est en maintenance, arrêté ou en erreur.
      Les serveurs de standby à chaud sont utilisés si tous les serveurs et
      serveurs de remplacement du jeu de serveurs du répartiteur de charge sont
      indisponibles. Les jeux de serveurs du répartiteur de charge (avec leurs
      serveurs de standby et de remplacement à chaud respectifs) sont toujours
      sollicités dans l'ordre du plus bas lbset vers le plus haut.
    
    

  
    top
    

    

    Gestion du répartiteur de charge
    
    

    
    
     L'application balancer-manager fournie avec le mandataire inverse
     d'Apache httpd en est un des outils les plus utiles. Comme
     mod_status, balancer-manager affiche la
     configuration et l'activité actuelles des balancers actifs. L'affichage de
     ces informations n'est cependant pas sa seule fonction ; il permet aussi de
     modifier la plupart d'entre elles et même d'ajouter des membres au groupe
     de répartition de charge en temps réel. Pour activer ces fonctionnalités,
     vous devez ajouter les lignes suivantes à votre fichier de configuration : 
    
    

    
    <Location "/balancer-manager">
    SetHandler balancer-manager
    Require host localhost
</Location>
    


    
    Avertissement
    
      
    N'activez le balancer-manager que si vous avez déjà sécurisé votre serveur.
      Assurez-vous en particulier que l'accès à l'URL soit fortement restreint.
    
    
    

    
    
      Lorsque vous accédez au serveur mandataire avec une adresse du style
      http://rproxy.example.com/balancer-manager/, la page suivante
      s'affiche :
    
    
    
    balancer-manager page
    

    
    
      Ce formulaire permet à l'administrateur de modifier certains paramètres,
      de désactiver ou d'ajouter certains serveurs d'arrière-plan, et de
      modifier les règles de répartition de charge. Par exemple, si on clique
      sur le répartiteur, la page suivante s'affiche : 
    
    
    
    balancer-manager page
    

    
    
      Si on clique sur un membre du groupe de répartition de charge, la page
      suivante s'affiche :
    
    
    
    balancer-manager page
    

    
    
      Si vous souhaitez que ces modifications soient conservées après un
      redémarrage du serveur, assurez-vous que la directive BalancerPersist soit définie à On.

    Vérification dynamique du bon fonctionnement d'un serveur
    d'arrière-plan
    
    

    
    
      Avant que le mandataire httpd ne fasse appel à un serveur d'arrière-plan, il
      peut "tester" si ce dernier est disponible en définissant le
      paramètre ping de ce serveur via la directive ProxyPass. Cependant, il est souvent plus
      judicieux de vérifier le bon fonctionnement d'un serveur hors
      bande et de manière dynamique via le module
      mod_proxy_hcheck d'Apache httpd.
    
    

  
    top
    

    

    Drapeaux d'état d'un membre du groupe de répartition de charge
    
    

    
    
      balancer-manager permet d'afficher et de modifier l'état d'un
      membre du groupe de répartition de charge. Les différents états et leurs
      significations sont les suivants :
    
    
      
    
      	
    DrapeauSigleDescription
    
      	
     OkLe serveur est disponible
    
      	
     InitLe serveur a été initialisé
    
        
    DDisLe serveur est
	désactivé et n'accepte aucune requête ; il sera retesté automatiquement.
    
        
    SStopLe serveur a été
	arrêté par l'administrateur ; il n'accepte aucune requête et il ne sera
	pas retesté automatiquement.
    
        
    IIgnLes erreurs
	concernant ce serveur sont ignorées et il sera donc toujours considéré
	comme disponible.
    
	
    RSparLe serveur cible sert de remplaçant à
	 chaud. Lorsqu'un serveur cible avec un lbset donné est inutilisable
	 (maintenance, arrêt, en erreur, etc...), un serveur de remplacement à
	 chaud libre de même lbset sera utilisé à sa place. Les remplaçants à
	 chaud permettent de s'assurer qu'un nombre déterminé de serveurs cibles
	 sera toujours disponible pour un répartiteur de charge.
    
        
    HStbyLe serveur est en
	mode hot-standby et ne sera donc utilisé que si aucun autre serveur ou
	serveur de remplacement	n'est disponible dans le jeu de serveurs du
	répartiteur de charge.
    
        
    EErrLe serveur est en
	erreur, en général suite à un test préalable à une requête ; aucune
	requête ne lui sera soumise, mais il sera retesté en fonction de la
	valeur de son paramètre retry.
    
        
    NDrnLe serveur est en
	mode drain ; il n'acceptera de requêtes que dans le cadre des sessions
	persistantes qui lui sont réservées et ignorera toutes les autres.
    
        
    CHcFlLe serveur a échoué
	au test dynamique de bon fonctionnement et ne sera utilisé que lorsqu'il
	aura réussi un test ultérieur.

    Introducción
    
	    
		
    Módulos RelacionadosDirectivas Relacionadas
    

    	
    CGI (Common Gateway Interface) es un método por el cual
		un servidor web puede interactuar con programas externos de 
		generación de contenido, a ellos nos referimos comúnmente como 
		programas CGI o scripts CGI. Es el método más común y sencillo de
        mostrar contenido dinámico en su sitio web. Este documento es una 
		introducción para configurar CGI en su servidor web Apache, y de
		iniciación para escribir programas CGI.
    
	
    top
    

    

    Configurando Apache para permitir CGI
    
		

        
    Para conseguir que sus programas CGI funcionen correctamente,
	    deberá configurar Apache para que permita la ejecución de CGI. Hay
	    distintas formas de hacerlo.
    

        
    Nota: Si Apache ha sido compilado con soporte
        de módulos compartidos, necesitará que el módulo de CGI esté cargado;
        en su httpd.conf tiene que asegurarse de que la directiva
        LoadModule
        no ha sido comentada. Una directiva configurada correctamente sería así:
            
            
    LoadModule cgid_module modules/mod_cgid.so
    


        En Windows, o si usa un mpm que no es multihilo, como prefork, una 
        directiva configurada correctamente podría definirse así: 

        
    LoadModule cgi_module modules/mod_cgi.so
    

    

        
    ScriptAlias
    
            

            
    La directiva
            ScriptAlias
            indica a Apache que un directorio se ha configurado específicamente
            para programas CGI. Apache asumirá que cada fichero en este 
            directorio es un programa CGI, e intentará ejecutarlos cuando un
            cliente solicita este recurso.
    
        
            
    La directiva 
            ScriptAlias se puede 
            definir así:
    

            
    ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/"
    

        
            
    El ejemplo que se muestra es de un archivo de configuración
            httpd.conf por defecto si usted instaló Apache
            en la ubicación por defecto. La directiva
            ScriptAlias es muy 
            parecida a la directiva Alias,
            ésta define un prefijo de URL que se enlaza a un directorio 
            en particular. Alias y
            ScriptAlias se usan generalmente para 
            directorios que se encuentran fuera del directorio 
            DocumentRoot. La diferencia
            entre Alias y ScriptAlias
            es que en ScriptAlias cualquier elemento
            debajo de ese prefijo de URL será considerado un programa CGI. Así, 
            el ejemplo de más arriba le indica a Apache que
            cualquier solicitud para un recurso que comience con 
            /cgi-bin/ debería servirse desde el directorio
            /usr/local/apache2/cgi-bin/, y debería tratarse como un
            programa CGI.
    

            
    Por ejemplo, si se solicita la URL
            http://www.example.com/cgi-bin/test.pl,
            Apache intentará ejecutar el archivo
            /usr/local/apache2/cgi-bin/test.pl y dar
            el resultado. Por supuesto el archivo debe existir y ser ejecutable, 
            y dar el resultado de una manera específica o Apache devolverá
            un mensaje de error.
    
        

        
    CGI fuera de directorios ScriptAlias
    
            

            
    Los programas CGI habitualmente se restringen a los directorios de
            ScriptAlias por razones de
            seguridad. De esta manera, los administradores pueden controlar de una
            manera más segura quien puede ejecutar programas CGI. Aun así, si no
            se toman suficientes precauciones, no hay ninguna razón por la que
            programas CGI no se puedan ejecutar desde directorios seleccionados de 
            manera arbitraria. Por ejemplo, quizás quiera permitir que usuarios del
            sistema tengan contenido web en sus directorios home con la directiva
            UserDir. Si quieren 
            tener sus propios programas CGI, pero no tienen acceso al directorio 
            principal cgi-bin, necesitarán ser capaces de 
            ejecutar sus scripts CGI en algún otro sitio.
    
      
            
    Hay dos pasos a seguir para permitir la ejecución CGI en directorios
            seleccionados de manera arbitraria. Primero, el handler 
            cgi-script debe estar activado usando la directiva 
            AddHandler o la directiva 
            SetHandler. Segundo, el parámetro
            ExecCGI debe estar definido en la directiva
            Options.
    
        

        
    Usando Options de manera explícita para permitir ejecución de 
            CGI
    
            

            
    Puede usar la directiva 
            Options, en el archivo de 
            configuración principal para especificar que se permite la ejecución 
            de CGI en un directorio en particular:
    

            
    <Directory "/usr/local/apache2/htdocs/somedir">
    Options +ExecCGI
</Directory>
    

            
            
    Esta directiva de aquí arriba le indica a Apache que debe 
            permitir la ejecución de archivos CGI. También necesitará indicarle 
            al servidor que los archivos son archivos CGI. La directiva 
            AddHandler le indica al 
            servidor que debe tratar a todos los archivos con la extensión 
            cgi o pl como programas CGI:
    

            
    AddHandler cgi-script .cgi .pl
    

        

        
    Ficheros .htaccess
    
            

            
    El tutorial .htaccess
            enseña como activar programas CGI si no tienes acceso a 
            httpd.conf.
    
        

        
    Directorios de Usuario
    
            

            
    Para permitir la ejecución de programas CGI para cualquier 
            archivo que acabe en .cgi en directorios de usuario, 
            puedes usar la siguiente configuración:
    

            
    <Directory "/home/*/public_html">
    Options +ExecCGI
    AddHandler cgi-script .cgi
</Directory>
    


            
    Si quiere designar un subdirectorio cgi-bin dentro 
            de un directorio de usuario en el que todos los ficheros serán 
            tratados como un programa CGI, puede usar lo siguiente:
    

            
    <Directory "/home/*/public_html/cgi-bin">
    Options ExecCGI
    SetHandler cgi-script
</Directory>
    

        
    
    top
    

    

    Escribiendo un programa CGI
    
        

        
    Hay dos diferencias principales entre programación ``regular'' y 
        programación en CGI.
    

        
    Primera, el resultado al completo de tu programa CGI debe estar 
        precedido de una cabecera MIME-type. Esta
        cabecera HTTP le indica al cliente que tipo de contenido está
        recibiendo. La mayor parte de las veces, ésto será algo como:
    

        
    
            Content-type: text/html
        
    

        
    Segunda, el resultado debe estar en formato HTML, o cualquier 
        otro formato que su navegador sea capaz de mostrar. La mayor
        parte de las veces, será HTML, pero otras escribirá un programa
        CGI que devuelve una imagen gif, u otro contenido no-HTML.
    

        
    Aparte de estas dos cosas, escribir un programa en CGI se 
        parecerá bastante a cualquier otro programa que vaya a escribir.
        
    


        
    Su primer programa CGI
    
            

            
    A continuación podrá ver un ejemplo de programa CGI que muestra
            una línea de texto en su navegador. Escriba lo siguiente, 
            guárdelo en un archivo con el nombre first.pl, y 
            póngalo en su directorio cgi-bin.
    

            
    #!/usr/bin/perl
print "Content-type: text/html\n\n";
print "Hola, Mundo.";
    


            
    Incluso si Perl no le resulta familiar, podrá ver lo que está
            ocurriendo aquí. La primera línea le dice a Apache (o a
            cualquier shell en la que se esté ejecutando) que este programa
            puede ejecutarse con el intérprete en la ubicación
            /usr/bin/perl. La segunda línea imprime la
            declaración de Content-Type que mencionamos antes, seguida de 
            dos pares de retornos de carro. Esto pone una línea en blanco 
            después de la cabecera para indicar el final de las cabeceras
            HTTP, y el comienzo del cuerpo del contenido. La tercera 
            imprime la cadena de caracteres "Hola, Mundo.". Y ese es el 
            final del programa.
    

            
    Si lo abre con su navegador favorito y le dice que solicite la 
            dirección
    

            
    
                http://www.example.com/cgi-bin/first.pl
            
    

            
    o donde quiera que pusiera el archivo, verá una línea
            Hola, Mundo. aparecerán la ventana del navegador. No es 
            muy emocionante, pero una vez que consiga que funcione podrá hacer 
            lo mismo con casi cualquier programa.
    
        
    
    top
    

    

    ¡Pero todavía no funciona!
    
        

        
    Hay 4 cosas básicas que puede llegar a ver en su navegador cuando
        intenta acceder a un programa CGI desde la web:
    

        
    
            
    El resultado del programa CGI
    
            
    ¡Genial! Esto indica que todo funcionó correctamente. Si el
            resultado es correcto, pero el navegador no lo procesa
            correctamente, asegúrese de que tiene especificado 
            correctamente el Content-Type en su programa 
            CGI.
    

            
    El código fuente de su programa CGI o un mensaje del tipo 
            "POST Method Not Allowed".
    

            
    Eso significa que no ha configurado Apache de manera
            apropiada para interpretar su programa CGI. Relea la sección
            de Configurando Apache e intente
            encontrar qué le falta.
    

            
    Un mensaje que empieza con "Forbidden"
    
            
    Eso significa que hay un problema de permisos. Compruebe el
            Log de Errores de Apache y la
            sección de más abajo de Permisos de
            Fichero.
    

            
    Un mensaje indicando "Internal Server Error"
    
            
    Si comprueba el Log de errores de
            Apache, probablemente encontrará que indica "Premature 
            end of script headers", posiblemente acompañado de otro 
            mensaje de error generado por su programa CGI. En este caso, 
            querrá comprobar cada una de las secciones de más adelante 
            para ver qué impide que su programa CGI genere las cabeceras 
            HTTP adecuadas.
    
            
    

        
    Permisos de Fichero
    
            

            
    Recuerde que el servidor no se ejecuta con su usuario. Es decir,
            cuando el servidor arranca, está funcionando con un usuario sin
            privilegios, generalmente el usuario nobody, o
            www-data, así que necesitará permisos extra para
            ejecutar los archivos de los que usted es dueño. Generalmente, 
            el método para dar permisos suficientes para que se pueda 
            ejecutar con nobody es dar permisos de ejecución a 
            todo el mundo en el fichero:
    

            
    
                chmod a+x first.pl
            
    

            
    Además, si su programa lee desde o escribe a cualquier otro/s
            archivo/s, esos archivos necesitarán tener los permisos correctos
            para permitir esas acciones.
    

        

        
    Información de Ruta y Entorno
    
            

            
    Cuando ejecuta un programa desde la línea de comandos, usted tiene
            cierta información que se le pasa a la shell sin que usted se
            percate de ello. Por ejemplo, usted tiene un PATH,
            que le indica a la shell dónde debe buscar archivos a los que usted
            hace referencia.
    

            
    Cuando un programa se ejecuta a través del servidor web como un
            programa CGI, puede que no tenga el mismo PATH. 
            Cualquier programa que invoque desde su programa CGI (como por
            ejemplo sendmail) necesitará que se le indique la
            ruta absoluta, así la shell puede encontrarlos cuando intenta 
            ejecutar su programa CGI.
    

            
    Una manifestación común de esto es la ruta del intérprete del 
            script (a menudo perl) indicado en la primera línea
            de su programa CGI, que parecerá algo como:
    

            
    #!/usr/bin/perl
    


            
    Asegúrese de que éste es de hecho el path de su intérprete.
    
            
    
            Cuando edita scripts CGI en Windows, los caracteres de retorno de
            carro podrían añadirse a la línea donde se especifica el intérprete. 
            Asegúrese de que los archivos se transfieren al servidor en modo 
            ASCII. Fallar en esto puede acabar con avisos del tipo "Command not 
            found" del Sistema Operativo, debido a que éste no reconoce los 
            caracteres de final de línea interpretados como parte del nombre
            de fichero del intérprete.
            
    
        

        
    Faltan Variables de Entorno
    
            

            
    Si su programa CGI depende de variables de entorno no estándar, necesitará
            asegurarse de que Apache pasa esas variables.
    

            
    Cuando no encuentra ciertas cabeceras HTTP del entorno, asegúrese 
            de que están formateadas según el 
            RFC 2616, 
            sección 4.2: Nombres de Cabeceras deben empezar con una letra, 
            seguida solo de letras, números o guión. Cualquier cabecera 
            que no cumpla esta regla será ignorada de manera silenciosa.
    

        

        
    Errores de Programa
    
            

            
    La mayor parte de las veces cuando un programa CGI falla, es por un 
            problema en el programa mismo. Esto ocurre generalmente cuando se 
            maneja bien con "esto del CGI", y ya no comete los dos errores
            mencionados más arriba. Lo primero que hay que hacer es asegurarse
            de que su programa se ejecuta correctamente en línea de comandos 
            antes de probarlo a través del servidor web.  Por ejemplo, 
            intente:
    

            
    
                cd /usr/local/apache2/cgi-bin
    
                ./first.pl
            
    

            
    (No llame al intérprete de perl. La consola y Apache 
            tienen que poder encontrar el intérprete usando línea 
            línea de información en la primera 
            línea del script.)
    

            
    Lo primero que debe ver escrito por su programa es un conjunto de 
            cabeceras HTTP, incluyendo el Content-Type,
            seguido de una línea en blanco.  Si ve alguna otra cosa, Apache
            devolverá el error Premature end of script headers si
            intenta lanzar el script en el servidor web. Vea 
            Escribiendo un programa CGI más arriba para
            más detalle.
    
        

        
    Log de Errores
    
            

            
    El log de errores es su amigo. Cualquier cosa que vaya mal generará 
            un mensaje en el log de errores. Debería mirar siempre ahí primero. 
            Si el lugar donde está alojando su sitio web no permite que acceda
            al log de errores, probablemente debería alojarlo en otro sitio.
            Aprenda a leer el log de errores y se dará cuenta de que enseguida
            averiguará el motivo del error y lo solucionará rápidamente.
    
        

        
    Suexec
    
            

            
    El programa de soporte suexec permite
            que programas CGI se ejecuten con permisos de usuario distintos,
            dependiendo del virtualhost o el directorio home donde se 
            encuentren. Suexec tiene una comprobación de permisos muy estricta, 
            y cualquier fallo en esa comprobación dará como resultado un error
            con el mensaje Premature end of script headers.
    

            
    Para comprobar si está usando Suexec, ejecute 
            apachectl -V y compruebe la ubicación de 
            SUEXEC_BIN. Si Apache encuentra un binario 
            suexec al arrancar, suexec se activará.
    

            
    A menos que comprenda suxec perfectamente, no debería usarlo.
            Para desactivar suexec, basta con eliminar el binario 
            suexec al que apunta SUEXEC_BIN y 
            reiniciar el servidor. Si después de leer sobre 
            suexec todavía quiere usarlo, entonces
            ejecute suexec -V para encontrar la ubicación del 
            fichero log de suexec, y use ese log para encontrar que política no
            está cumpliendo.

    ¿Qué ocurre entre bastidores?
    
        

        
    En cuanto tenga conocimiento avanzado de programación CGI, le será 
        útil comprender más de lo que ocurre entre bastidores. 
        Específicamente, cómo el navegador y el servidor se comunican el uno
        con el otro. Porque aunque esté muy bien escribir un programa que 
        diga "Hola, Mundo.", no tiene una gran utilidad.
    

        
    Variables de Entorno
    
            

            
    Las variables de entorno son valores que están ahí cuando 
            usa el ordenador. Son cosas útiles como el path (donde su ordenador
            busca el archivo específico que se lanza cuando usted escribe un 
            comando), su nombre de usuario, el tipo de terminal que usa, etc. 
            Para una lista completa de la variables de entorno normales que se 
            se usan en su día a día escriba env en la línea de 
            comandos.
    

            
    Durante la transacción CGI, el servidor y el navegador también 
            configuran variables de entorno, y así pueden comunicarse entre 
            ellos. Cosas como el tipo de navegador (Netscape, IE, Lynx), el tipo
            de servidor (Apache, IIS, WebSite), el nombre del programa CGI que
            se está ejecutando, etc.
    

            
    Estas variables están disponibles para el programador de CGI, y son 
            la mitad de la historia de la comunicación cliente-servidor. La 
            lista completa de las variables necesarias se encuentra en 
            el RFC de Common Gateway
            Interface.
    

            
    Este sencillo programa CGI en Perl mostrará todas las variables 
            de entorno que se están pasando entre el cliente y el navegador. Dos
            programas similares están incluidos en el directorio 
            cgi-bin de la distribución de Apache. Tenga en cuenta
            que algunas variables son necesarias mientras que otras son 
            opcionales, así que es posible que vea algunas variables que no 
            están en la lista oficial. Adicionalmente, Apache aporta distintas
            maneras diferentes para que pueda
            añadir sus variables de entorno a las 
            básicas que se proveen por defecto.
    

            
    #!/usr/bin/perl
use strict;
use warnings;

print "Content-type: text/html\n\n";
          
foreach my $key (keys %ENV) {
    print "$key --> $ENV{$key}<br>";
}
    

        

        
    STDIN y STDOUT
    
            

            
    Otra comunicación entre el servidor y el cliente ocurre en la 
            entrada estándar (STDIN) y la salida estándar 
            (STDOUT). En el contexto normal de cada día, 
            STDIN es la entrada con el teclado, o un fichero que se 
            le da a un programa para que actúe sobre él, y STDOUT
            generalmente es la consola o la pantalla.
    

            
    Cuando hace POST con un formulario de web a un programa 
            CGI, los datos en ese formulario se empaquetan en un formato especial
            que se entrega a su programa CGI en el STDIN.
            Entonces el programa puede procesar la información como si le llegara
            desde el teclado, o desde un fichero.
    

            
    El "formato especial" es muy sencillo. Un nombre de campo y su 
            valor se asocian juntos con el signo igual (=), y pares de valores 
            se asocian juntos con el ampersand ó et en español (&). 
            Caracteres inconvenientes como los espacios, ampersands y signos de 
            igual, se convierten en su equivalente hexadecimal para no impidan 
            el funcionamiento correcto del programa. La cadena de datos al 
            completo será algo como:
    

  
    
        name=Rich%20Bowen&city=Lexington&state=KY&sidekick=Squirrel%20Monkey
  
    

            
    A veces tendrá este tipo de cadena de caracteres al final de una 
            URL. Cuando esto ocurre, el servidor pone esa cadena en una variable 
            de entorno que se llama QUERY_STRING. Esto se llama 
            solicitud GET. Su formulario HTML especifica si se usa 
            un GET o un POST para entregar la 
            información, configurando el atributo METHOD en la 
            etiqueta FORM.
    

            
    Su programa es el responsable de convertir esa cadena de 
            caracteres en información útil. Afortunadamente, hay librerías y 
            módulos disponibles que ayudan a procesar la información, así como a 
            gestionar los distintos aspectos de su programa CGI.

    Módulos/librerías CGI
    
        

        
    Cuando escribe programas CGI, debería considerar usar una librería de
        código, o módulo, para hacer todo el trabajo más arduo por usted.
        Esto lleva a tener menos errores y un desarrollo de código más 
        rápido.
    

        
    Si está escribiendo un programa CGI en Perl, existen módulos 
        disponibles en CPAN. El módulo más
        conocido para este propósito es CGI.pm. Quizás quiera
        considerar CGI::Lite, que implementa una funcionalidad 
        mínima, que es todo lo que se necesita en la mayoría de los programas.
    

        
    Si está escribiendo programas CGI en C, hay varidad de opciones. Una
        de estas es la librería CGIC, de
        http://www.boutell.com/cgic/.
        
    
    
    top
    

    

    Para más información
    
        

        
    La especificación actual de CGI está disponible en el
        RFC de Common Gateway
        Interface.
    

        
    Cuando envíe una pregunta sobre un problema de CGI, o bien a una 
        lista de correo, o a un grupo de noticias, asegúrese de que facilita suficiente
        información de lo que ha ocurrido, de lo que espera que ocurra, y de 
        lo que está ocurriendo en su lugar que es diferente, el servidor que 
        está ejecutando, en qué lenguaje CGI está hecho su programa, y si es
        posible, el código que falla. Esto hará encontrar el problema mucho más 
        fácil.
    

        
    Tenga en cuenta que las preguntas sobre problemas CGI 
        nunca deberían enviarse a la base de datos de bugs de
        bugs de Apache a menos que esté seguro de haber encontrado un 
        problema en el código fuente de Apache.

    Authentification et autorisation
    
      
    
        
    L'authentification représente tout processus par lequel vous
	vérifiez si quelqu'un correspond bien à la personne qu'il
	prétend être. L'autorisation représente tout processus
	permettant de savoir si une personne est autorisée à aller là où
	elle veut aller, ou à obtenir les informations qu'elle demande.

    Contrôle d'accès
    
      
    
        
    Le contrôle d'accès se réfère au processus permettant
	d'interdire ou d'accorder l'accès à une ressource en fonction de
	certains critères, et il existe de nombreuses façons d'y
	parvenir.

    Contenu dynamique avec CGI
    
      
    
        
    L'interface CGI (Common Gateway Interface)
	fournit au serveur web une méthode d'interaction avec des
	programmes externes générateurs de contenu, souvent nommés
	programmes CGI ou scripts CGI. Il s'agit d'une méthode
	simple permettant d'ajouter du contenu
	dynamique à votre site web. Ce document se veut une introduction
	à la configuration de CGI sur votre serveur web Apache et à
	l'écriture de programmes CGI.
    

        
    Voir CGI : contenu dynamique
    
      
    
    
    

    
    
      
    Fichiers .htaccess
    
      
    
        
    Les fichiers .htaccess permettent de modifier la
	configuration du serveur au niveau de chaque répertoire. À cet
	effet, un fichier est placé dans un répertoire particulier du site
	web, et les directives de configuration qu'il contient s'appliquent à ce
	répertoire et à tous ses sous-répertoires.

    HTTP/2 avec httpd
    
      
    
      
    HTTP/2 est une évolution du protocole de la couche application le plus
      connu au monde, HTTP. Les efforts se sont concentrés sur une amélioration
      de l'efficacité de l'utilisation des ressources réseau sans modifier la
      sémantique de HTTP. Ce guide explique la manière dont HTTP/2 est
      implémenté dans httpd, donne des conseils pour une configuration de base
      ainsi qu'une liste de recommandations.

    Introduction au Inclusions côté Serveur (Server Side Includes
      ou SSI)
    
      
    
        
    Les SSI sont des directives que l'on place dans des pages
	HTML, et qui sont évaluées par le serveur lorsque ces pages sont
	servies. Elles vous permettent d'ajouter du contenu généré
	dynamiquement à une page HTML existante, sans avoir à servir
	l'intégralité de la page via un programme CGI, ou toute autre
	technologie dynamique.

    Répertoires web de l'utilisateur
    
      
    
        
    Sur les systèmes multi-utilisateurs, vous pouvez permettre à
	chaque utilisateur d'avoir un site web dans son répertoire home
	via la directive UserDir. Les visiteurs de l'URL
	http://example.com/~nom-utilisateur/ vont recevoir
	du contenu situé dans le répertoire home de l'utilisateur
	"nom-utilisateur", et dans le sous-répertoire
	spécifié par la directive UserDir.

    Mandataires inverses
    
      
    
        
    Apache httpd possède des fonctionnalités évoluées de serveur
	mandataire inverse via ses directives ProxyPass et BalancerMember qui permettent
	d'implémenter un système de mandataire inverse sophistiqué garantissant
	une haute disponibilité, une répartition et une réattribution de charge,
	un regroupement de serveurs en grappe (clustering) basé sur le cloud et
	une reconfiguration dynamique à la volée.

    Réécriture d'URLs avec mod_rewrite
    
      
    
        
    La réécriture d'URLs avec (ou sans) mod_rewrite devient
	l'une des questions les plus fréquentes posées dans nos listes de
	diffusion et nos canaux IRC. C'est pourquoi nous avons dédié une section entière de notre documentation à des
	howtos et recettes sur ce sujet.

log_server_status - Log periodic status summaries - Apache HTTP Server Version 2.4

    Apache HTTP Server Version 2.4

    log_server_status - Log periodic status summaries
    

    

    Available Languages:  en  |
 fr 
    

    

    
    This perl script is designed to be run at a frequent interval by
    something like cron. It connects to the server and downloads the status
    information. It reformats the information to a single line and logs it to
    a file. Adjust the variables at the top of the script to specify the
    location of the resulting logfile. mod_status will
    need to be loaded and configured in order for this script to do its
    job.
    

    

    top
    

    

    Usage
    


    The script contains the following section.
    


    my $wherelog = "/usr/local/apache2/logs/";  # Logs will be like "/usr/local/apache2/logs/19960312"
my $server   = "localhost";        # Name of server, could be "www.foo.com"
my $port     = "80";               # Port on server
my $request = "/server-status/?auto";    # Request to send
    



    You'll need to ensure that these variables have the correct values,
and you'll need to have the /server-status handler
configured at the location specified, and the specified log location
needs to be writable by the user which will run the script.
    


    Run the script periodically via cron to produce a daily log file,
which can then be used for statistical analysis.

    suexec, CGI programlarını çalıştırmadan
    önce Apache HTTP Sunucusu tarafından kullanıcı değiştirmek için kullanılır.
    Bunu yapabilmek için sunucunun root tarafından çalıştırılmış
    olması gerekir. HTTP artalan süreci normalde root aidiyetinde
    çalışmadığından suexec'in çalıştırılabilir
    dosyasının sahibi root olmalı, setuid biti etkin
    (u+s) olmalı ve dosyaya root dışında hiç kimse
    yazamamalıdır.
    

    
    suexec güvenlik modeli ve kavramlar

apxs - Apache Eklenti Aracı - Apache HTTP Sunucusu Sürüm 2.4

    Apache HTTP Sunucusu Sürüm 2.4

    apxs - Apache Eklenti Aracı
    

    

    Mevcut Diller:  en  |

 tr 
    

    

    
    apxs, Apache Hiper Metin Aktarım
     Protokolü (HTTP) sunucusu için ek modül derleme ve kurulum aracıdır. Bu
     araç sayesinde, bir veya daha fazla kaynak veya nesne
     dosyasından bir devingen paylaşımlı nesne (DSO - "Dynamic
     Shared Object" kısaltması) derlemek ve bu nesneyi (modülü) Apache
     sunucusuna çalışma anında mod_so
     modülünün LoadModule yönergesi üzerinden yüklemek mümkün
     olmaktadır.
    

    
    Bu eklenti mekanizmasını platformunuzda kullanmak için DSO desteğinin
     olması ve httpd programının
     mod_so modülünü içerecek şekilde
     derlenmiş olması gerekir. Eğer bunlar mevcut değilse
     apxs aracı durumu size bildirecektir. Bunu
     aşağıdaki komutla kendiniz de sınayabilirsiniz:
    

    
    
      $ httpd -l
    
    

    
    mod_so modülü gösterilen listede yer
     almalıdır. Bu gereksinimler sağlandığı takdirde
     apxs aracı sayesinde DSO mekanizması
     üzerinden kendi modüllerinizi kurmak suretiyle Apache sunucunuzun
     işlevselliğini kolayca arttırabilirsiniz. Örnek bir uygulama:
    

    
    
      $ apxs -i -a -c mod_foo.c
    
      gcc -fpic -DSHARED_MODULE -I/dosya/yolu/apache/include -c mod_foo.c
    
      ld -Bshareable -o mod_foo.so mod_foo.o
    
      cp mod_foo.so /dosya/yolu/apache/modules/mod_foo.so
    
      chmod 755 /dosya/yolu/apache/modules/mod_foo.so
    
      [`foo' modülü /dosya/yolu/apache/etc/httpd.conf'ta etkinleştiriliyor]
    
      $ apachectl restart
    
      /dosya/yolu/apache/sbin/apachectl restart: httpd not running, trying to start
    
      [Tue Mar 31 11:27:55 1998] [debug] mod_so.c(303): loaded module foo_module
    
      /dosya/yolu/apache/sbin/apachectl restart: httpd started
    
      $ _
    
    

    
    dosya olarak bir C kaynak dosyası (.c), bir nesne dosyası
     (.o) ve hatta bir kütüphane arşivi archive (.a) belirtebilirsiniz.
     apxs aracı bu dosya uzantılarını
     tanıdığından C dosyalarını derleme işleminden, arşiv ve nesne
     dosyalarını ise doğrudan ilintileme işleminden geçirir. Fakat böyle
     önceden derlenmiş nesne dosyalarını kullanırken, devingen paylaşımlı
     nesne olarak kullanılmalarını sağlamak üzere konumdan bağımsız kod (PIC)
     üretecek şekilde derlenmiş olduklarından emin olmalısınız. Örneğin
     GCC'yi bunun için daima -fpic seçeneği ile
     kullanmalısınız. Diğer C derleyiciler için,
     apxs'in nesne dosyalarını derlerken
     kullanacağı seçenekleri öğrenmek için o derleyicilerin kılavuz
     sayfalarına bakınız.
    

    
    Apache'deki DSO desteği ile ilgili daha ayrıntılı bilgi edinmek için
     mod_so belgesini okumakla yetinmeyip
     src/modules/standard/mod_so.c kaynak dosyasını da
     okuyunuz.

         ismi belirtmek için bu seçeneği kullanın.
         -g seçeneği için bu gereklidir.
         -i seçeneği için ise araç, modül

         değişkenleri değerleriyle birlikte basar. İsteğe bağlı
         -v seçeneği liste çıktısını biçemler.

         
    Modülünüzü yükleyecek httpd'yi
          derlemek için kullanılacak ayarları elle belirtmek için kullanılır.
          Örneğin, Apache'nin C başlık dosyalarının yerini kendi Makefile
          dosyalarınızın içinde şöyle belirtebilirsiniz:
    
        
    
          INC=-I`apxs -q INCLUDEDIR`

    Şablon Üretme Seçenekleri
    
      
    
      
    -g
    
      
    modüladı (-n
       seçeneğine bakınız) adında bir alt dizin oluşturur ve içine iki dosya
       yerleştirir: Kendi modülünüzü oluşturabilmeniz için veya
       apxs mekanizmaları ile hemen oynamaya
       başlayabilmeniz için mod_modüladı.c adında bir
       modül kaynak dosyası örneği ve bu modülü derleyip kurmayı
       kolaylaştırmak için bir Makefile dosyası.
    
      
    
    

    
    DSO Derleme Seçenekleri
    
      
    
      
    -c
    
      
    Bu seçenek derleme yapılacağını belirtir. Önce belirtilen C kaynak
       dosyalarını (.c), nesne dosyalarını (.o) elde etmek için
       derler. Sonra bunları kalan nesne dosyaları (.o ve .a) ile
       ilintileyerek dso-dosyası adında bir devingen paylaşımlı
       nesne oluşturur. Eğer -o seçeneği ile
       modül ismi belirtilmemişse dosyalar arasındaki ilk dosyanın
       ismine bakarak dosya ismi tahmin edilmeye çalışılır ve
       mod_isim.so dosya adı bu isimden elde
       edilir.
    

      
    -o dso-dosyası
    
      
    Oluşturulacak devingen paylaşımlı nesnenin ismini belirtmek için
       kullanılır. Modül ismi bu seçenekle belirtilmez ve dosya

    Örnekler
    
    
    Apache'nin sunucu işlevselliğini genişletmek amacıyla kullanacağınız
     mod_foo.c adında bir Apache modülünüz olduğunu varsayalım.
     Öncelikle, C kaynak dosyasını, Apache sunucusuna çalışma anında
     yüklenmeye uygun bir paylaşımlı nesne olarak derlemeniz gerekir. Bunu
     sağlamak için şu komutları vermelisiniz:
    

    
    
      $ apxs -c mod_foo.c
    
      /dosya/yolu/libtool --mode=compile gcc ... -c mod_foo.c
    
      /dosya/yolu/libtool --mode=link gcc ... -o mod_foo.la mod_foo.slo
    
      $ _
    
    

    
    Bundan sonra, Apache yapılandırmanızın bu paylaşımlı nesneyi yüklemek
     için bir LoadModule yönergesi içermesini
     sağlamalısınız. apxs bu adımı
     basitleştirmek amacıyla, paylaşımlı nesneyi sunucunun modules
     dizinine özdevinimli olarak kurmak ve httpd.conf dosyasını
     buna uygun olarak güncellemek için bir yol sağlar. Bu sonuç şöyle elde
     edilebilir:
    

    
    
      $ apxs -i -a mod_foo.la
    
      /dosya/yolu/instdso.sh mod_foo.la /path/to/apache/modules
    
      /dosya/yolu/libtool --mode=install cp mod_foo.la /dosya/yolu/apache/modules
      ...
      chmod 755 /dosya/yolu/apache/modules/mod_foo.so
    
      [`foo' modülü /dosya/yolu/apache/conf/httpd.conf'da etkinleştiriliyor] 
    
      $ _
    
    

    
    Yapılandıma dosyasına (eğer yoksa) şu satır eklenir:
    

    
    
      LoadModule foo_module modules/mod_foo.so
    
    

    
    Bunu öntanımlı olarak iptal etmek isterseniz
     -A seçeneğini kullanmanız gerekir:
    

    
    
      $ apxs -i -A mod_foo.c
    
    

    
    apxs mekanizmalarını hızlıca denemek
     için örnek bir Apache modül şablonunu ve bir Makefile dosyasını şöyle
     oluşturabilirsiniz:
    

    
    
      $ apxs -g -n foo
    
      Creating [DIR]  foo
    
      Creating [FILE] foo/Makefile
    
      Creating [FILE] foo/modules.mk
    
      Creating [FILE] foo/mod_foo.c
    
      Creating [FILE] foo/.deps
    
      $ _
    
    

    
    Ardından bu örnek modülü bir paylaşımlı nesne olarak derleyip Apache
     sunucusuna yükleyebilirsiniz:
    

    
    
      $ cd foo
    
      $ make all reload
    
      apxs -c mod_foo.c
    
      /dosya/yolu/libtool --mode=compile gcc ... -c mod_foo.c
    
      /dosya/yolu/libtool --mode=link gcc ... -o mod_foo.la mod_foo.slo
    
      apxs -i -a -n "foo" mod_foo.la
    
      /dosya/yolu/instdso.sh mod_foo.la /dosya/yolu/apache/modules
    
      /dosya/yolu/libtool --mode=install cp mod_foo.la /dosya/yolu/apache/modules
      ...
       chmod 755 /dosya/yolu/apache/modules/mod_foo.so
    
      [`foo' modülü /dosya/yolu/apache/conf/httpd.conf'ta etkinleştiriliyor]

    Le script configure permet de configurer
    l'arborescence des sources afin de compiler et installer le serveur
    HTTP Apache sur votre plate-forme spécifique. De nombreuses options
    vous permettent de compiler un serveur correspondant à vos propres
    besoins.
    

    
    Ce script, situé dans le répertoire racine de la distribution des
    sources, ne concerne que la compilation sur les systèmes Unix et
    apparentés. Pour les autres plates-formes, voir la documentation spécifique de ces
    dernières.

    Résumé
    
    
    Vous devez appeler le script configure depuis le
    répertoire racine de la distribution.
    

    
    ./configure [OPTION]...
    [VARIABLE=VALEUR]...
    

    
    Pour définir des variables d'environnement (par exemple
    CC,CFLAGS, etc...), utilisez la clause
    VARIABLE=VALEUR. Voir ci-dessous pour la description de quelques variables
    usuelles.
    

    top
    

    

    Options
    
  

  
    Options de Configuration
    

    
    Les options suivantes affectent le comportement du script
    configure.
    

    
    
      
    -C
    
      
    --config-cache
    
      
    C'est un alias pour --cache-file=config.cache
    

      
    --cache-file=FICHIER
    
      
    Les résultats des tests seront mis en cache dans le fichier
      FICHIER. Cette option est désactivée par défaut.
    

      
    -h
    
      
    --help [short|recursive]
    
      
    Affichage de l'aide et sortie du script. Avec l'argument
      short, seules les options spécifiques à ce paquet
      seront affichées. L'argument recursive permet
      d'afficher l'aide de tous les paquets inclus.
    

      
    -n
    
      
    --no-create
    
      
    Le script configure s'exécute normalement, mais
      ne crée pas les fichiers résultants. Ceci permet de vérifier les
      résultats des tests avant de générer les fichiers makefile pour la
      compilation.
    

      
    -q
    
      
    --quiet
    
      
    Les messages checking ... ne sont pas affichés au
      cours du processus de configuration.
    

      
    --srcdir=DIR
    
      
    Définit le répertoire DIR comme répertoire des
      fichiers sources. Par défaut, c'est le répertoire où se situe le
      script configure, ou le répertoire parent.
    

      
    --silent
    
      
    Identique à --quiet
    

      
    -V
    
      
    --version
    
      
    Affichage des informations de copyright et sortie du
      script.
    
    
    
  

  
    Répertoires
  d'installation
    

    
    Ces options permettent de spécifier le répertoire d'installation.
    L'arborescence de l'installation dépend de l'organisation (layout)
    sélectionnée.
    

    
    
      
    --prefix=PREFIX
    
      
    Installe les fichiers indépendants de l'architecture dans
      PREFIX. Par défaut, le répertoire d'installation est
      /usr/local/apache2.
    

      
    --exec-prefix=EPREFIX
    
      
    Installe les fichiers dépendants de l'architecture dans
      EPREFIX. La valeur par défaut de cette option
      correspond à la valeur de la variable
      PREFIX.
    
    
    

    
    Par défaut, make install va installer tous les
    fichiers dans /usr/local/apache2/bin,
    /usr/local/apache2/lib, etc... Vous pouvez cependant
    spécifier un préfixe d'installation autre que
    /usr/local/apache2 en utilisant l'option
    --prefix (par exemple --prefix=$HOME).
    

    
    Spécifier une organisation (layout) des
    répertoires
    
      
    
        
    --enable-layout=LAYOUT
    
        
    Configure le code source et les scripts de compilation de
	façon à ce que l'arborescence d'installation adopte
	l'organisation LAYOUT. Ceci vous permet de spécifier
	des chemins séparés pour chaque type de fichier de
	l'installation du serveur HTTP Apache. Le fichier
	config.layout contient de nombreux exemples de
	configurations, et vous pouvez créer vos propres configurations
	personnalisées en vous basant sur ces exemples. Les différentes
	organisations contenues dans ce fichier sont enregistrées sous
	forme de sections <Layout
	FOO>...</Layout> et référencées dans ce cas par
	le nom FOO. L'organisation par défaut
	est Apache.
    
      
    
    

    
    Configuration avancée des
    répertoires d'installation
    

      
    Pour une définition plus précise des répertoires
      d'installation, utilisez les options ci-dessous. Notez que les
      répertoires par défaut sont définis par autoconf, et
      que leurs valeurs sont écrasées par les valeurs correspondantes
      définies lors du choix de l'organisation des répertoires
      (layout).
    

      
    
        
    --bindir=DIR
    
        
    Installe les exécutables utilisateur dans DIR.
	Les exécutables utilisateur sont des programmes support comme
	htpasswd, dbmmanage,
	etc..., et destinés aux administrateurs du site. Par défaut,
	DIR est défini à
	EPREFIX/bin.
    

        
    --datadir=DIR
    
        
    Installe les données non modifiables indépendantes de
	l'architecture dans DIR. Par défaut,
	datadir est défini à

	par autoconf et actuellement inutilisée.
    

        
    --includedir=DIR
    
        
    Installe les fichiers d'en-têtes C dans DIR. Par
	défaut, includedir est défini à
	EPREFIX/include.
    

        
    --infodir=DIR
    
        
    Installe la documentation info dans DIR. Par
	défaut, infodir est défini à
	PREFIX/info. Cette option est
	actuellement inutilisée.
    

        
    --libdir=DIR
    
        
    Installe les fichiers objet des bibliothèques dans
	DIR. Par défaut, libdir est défini à
	EPREFIX/lib.
    

        
    --libexecdir=DIR
    
        
    Installe les exécutables du programme (autrement dit les
	modules partagés) dans DIR. Par défaut,
	libexecdir est défini à
	EPREFIX/modules.
    

        
    --localstatedir=DIR
    
        
    Installe les données temporaires modifiables spécifiques à
	la machine dans
	DIR. Par défaut, localstatedir est
	défini à PREFIX/var. Cette option est
	fournie par autoconf et est actuellement
	inutilisée.
    

        
    --mandir=DIR
    
        
    Installe les pages de manuel dans  DIR. Par
	défaut, mandir est défini à
	EPREFIX/man.
    

        
    --oldincludedir=DIR
    
        
    Installe les fichiers d'en-têtes C pour les programmes
	autres que gcc dans DIR. Par défaut,
	oldincludedir est défini à
	/usr/include. Cette option est fournie par
	autoconf et est actuellement inutilisée.
    

        
    --sbindir=DIR
    
        
    Installe les exécutables de l'administrateur système dans
	DIR. Ce sont les programmes du serveur comme
	httpd, apachectl,
	suexec, etc..., qui sont nécessaires à
	l'exécution du serveur HTTP Apache. Par défaut,
	sbindir est défini à
	EPREFIX/sbin.
    

        
    --sharedstatedir=DIR
    
        
    Installe les données modifiables indépendantes de
	l'architecture dans DIR. Par défaut,

	autoconf et est actuellement inutilisée.
    

        
    --sysconfdir=DIR
    
        
    Installe les données non modifiables spécifiques à la
	machine comme les fichiers de configuration du serveur
	httpd.conf, mime.types, etc... dans
	DIR. Par défaut, sysconfdir est défini à
	PREFIX/conf.
    
      
    
    
  

  
    Types de systèmes
    

    
    Ces options sont utilisées pour la cross-compilation du serveur
    HTTP Apache afin de pouvoir l'utiliser sur un autre système. Dans le
    cas général où la compilation et l'exécution du serveur ont lieu sur
    le même système, ces options ne sont pas utilisées.
    

    
    
      
    --build=BUILD
    
      
    Définit le type du système sur lequel les outils sont
      compilés. Par défaut, il s'agit de la chaîne renvoyée par le
      script config.guess.
    

      
    --host=HOST
    
      
    Définit le type du système sur lequel le serveur s'exécutera.
      Par défaut, HOST est identique à BUILD.
    

      
    --target=TARGET
    
      
    Configure pour construire des compilateurs pour le type de
      système TARGET. Par défaut, TARGET est
      identique à HOST. Cette option est fournie par
	autoconf et n'est pas requise par le serveur HTTP
	Apache.
    
    
    
  

  
    Fonctionnalités
  optionnelles
    

    
    Ces options vous permettent de configurer avec précision les
    fonctionnalités de votre futur serveur HTTP.
    

    
    Syntaxe générale
    
      
    D'une manière générale, vous pouvez utiliser la syntaxe
      suivante pour activer ou désactiver une fonctionnalité :
    

      
    
        
    --disable-FONCTIONNALITE
    
        
    Désactive la fonctionnalité FONCTIONNALITE.
	Identique à
	--enable-FONCTIONNALITE=no.
    

        
    --enable-FONCTIONNALITE[=ARG]
    
        
    Active la fonctionnalité FONCTIONNALITE. La
	valeur par défaut de ARG est yes.
    

        
    --enable-MODULE=shared
    
        
    Le module spécifié sera compilé en tant que module DSO. Par
	défaut, les modules activés sont liés dynamiquement.
    

        
    --enable-MODULE=static
    
        
    Le module correspondant sera lié statiquement.
    
      
    

      
    Note
    
        Si vous spécifiez --enable-foo, et si
	foo n'existe pas, configure ne le
	signalera pas ; vous devez donc prendre soin de taper les
	options correctement.
      
    
    

    
    Choix des modules à compiler
    
      
    La plupart des modules sont compilés par défaut et ils doivent être
      désactivés de manière explicite ou via le mots-clé few (voir
      ci-dessous --enable-modules,
      --enable-mods-shared et --enable-mods-static
      pour une explication plus détaillée), ou
      --enable-modules=none pour les désactiver tous.
    

      
    Par défaut, les autres modules ne sont pas compilés et doivent
      être activés explicitement, ou en utilisant les mots-clés
      all ou reallyall pour être disponibles.
    

      
    Pour déterminer quels modules sont compilés par défaut,
      exécutez la commande ./configure -h ou
      ./configure --help, et consultez les Optional
      Features. Par exemple, supposons que vous soyez intéressé
      par les modules mod_example1 et
      mod_example2, et que vous voyiez ceci :
    

        
    Optional Features:
  ...
  --disable-example1     example module 1
  --enable-example2      example module 2
  ...
    

        
    Le module mod_example1 est ici activé par
	défaut, et vous devez spécifier --disable-example1
	si vous ne voulez pas le compiler. Par contre, le module
	mod_example2 est désactivé par défaut, et vous
	devez spécifier --enable-example2 si vous voulez le
	compiler.
    

    

    
    Modules Multi-Processus
    
      
    Les Modules Multi-Processus, ou MPMs,
      constituent le coeur du serveur. Un seul MPM doit être actif pour
      que le serveur puisse fonctionner. Vous trouverez la liste des
      MPMs disponibles à module index page.
    

      
    Les MPMs peuvent être compilés en tant que modules DSO pour un
      chargement dynamique, ou liés statiquement avec le serveur, et
      sont activés via les options suivantes :
    

      
    
        
    --with-mpm=MPM
    
        
    
          
    Sélectionne le MPM par défaut pour votre serveur. Si les
	  MPMs sont compilés en tant que modules DSO (voir
	  --enable-mpms-shared), cette option spécifie le
	  MPM qui sera chargé par défaut selon le fichier de
	  configuration. Dans le cas contraire, cette option spécifie le
	  seul MPM disponible qui sera lié statiquement avec le
	  serveur.
    
          
    Si cette option est omise, c'est le MPM par défaut pour votre
	  système d'exploitation qui sera utilisé.
    
        
    

        
    --enable-mpms-shared=Liste de MPM
    
        
    
          
    Définit une liste de MPMs à compiler en tant que modules
	  dynamiquement partagés (DSO). Un de ces modules doit être
	  chargé dynamiquement via la directive LoadModule.
    
          
    Liste de MPM est une liste, entourée
	  d'apostrophes,  de noms de MPM séparés par des espaces. Par
	  exemple :
    
          
    
            --enable-mpms-shared='prefork worker'
          
    
          
    Vous pouvez aussi utiliser le mot-clé all, ce
	  qui aura pour effet de spécifier tous les MPMs qui supportent
	  le chargement dynamique sur la plate-forme considérée, et de
	  les compiler en tant que modules DSO. Par exemple :
    
          
    
            --enable-mpms-shared=all
          
    
	
    
      
    
    

    
    Modules tiers
    
      
    Pour ajouter des modules tiers, utilisez les options suivantes
      :
    

      
    
        
    --with-module=type-module:fichier-module[,
          type-module:fichier-module]
    
        
    Ajoute un ou plusieurs modules tiers à la liste des
	modules liés statiquement. Le fichier source du module
	fichier-module sera recherché dans le sous-répertoire
	type-module de l'arborescence des sources de votre
	serveur HTTP Apache. S'il ne l'y trouve pas,
	configure considèrera fichier-module
	comme un chemin de fichier absolu et essaiera de copier le
	fichier source dans le sous-répertoire type-module.
	Si ce sous-répertoire n'existe pas, il sera créé et un fichier
	Makefile.in standard y sera enregistré.
    
          
    Cette option est conçue pour ajouter de petits modules
	  externes ne comportant qu'un seul fichier source. Pour des
	  modules plus complexes, vous devrez lire la documentation du
	  fournisseur du module.
    
          
    Note
    
            Si vous voulez compiler un module DSO (lié de manière
	    dynamique au lieu de statique), utilisez le programme
	    apxs.
    
        
    

      
    
    

    
    Options cumulatives et autres
    options
    
      
    
        
    --enable-maintainer-mode
    
        
    Active les avertissements de débogage et de compilation et
	charge tous les modules compilés.
    

        
    --enable-mods-shared=LISTE-MODULES
    
        
    
          
    Définit une liste de modules à activer et à compiler en
	  tant que modules dynamiques partagés. Cela signifie que ces
	  modules doivent être chargés dynamiquement en utilisant la
	  directive LoadModule.
    
          
    LISTE-MODULES est une liste, entourée
	  d'apostrophes, de noms de modules
	  séparés par des espaces. Les noms
	  des modules sont spécifiés sans le préfixe mod_.
	  Par exemple :
    
          
    
            --enable-mods-shared='headers rewrite dav'
          
    
          
    Vous pouvez aussi utiliser les mots-clés reallyall,
	  all, most et few. Par
	  exemple,
    
          
    
            --enable-mods-shared=most
          
    
          
    va compiler la plupart des modules en tant que modules DSO,
    
	  
    
            --enable-mods-shared=few
          
    
          
    ne compilera qu'un jeu de modules de base.
    
          
    Le jeu par défaut correspond au mot-clé most.
    
            
	  
    Les directives LoadModule correspondant aux
	  différents modules choisis sont automatiquement générées dans
	  le fichier de configuration principal. Par défaut, toutes ces
	  directives sont mises en commentaire, sauf pour les modules
	  requis ou ceux explicitement sélectionnés par un argument
	  --enable-nom-module du script configure. Vous
	  pouvez modifier le jeu de modules chargé en activant ou
	  désactivant les directives LoadModule dans le fichier
	  httpd.conf. En outre, les directives LoadModule peuvent être activées
	  pour tous les modules compilés via l'option
	  --enable-load-all-modules du script configure.
    
          
        
    

        
    --enable-mods-static=MODULE-LIST
    
        
    Cette option produit le même effet que l'option
	--enable-mods-shared, à l'exception que les modules
	seront liés statiquement. Cela signifie que les modules
	spécifiés seront toujours disponibles au cours du fonctionnement
	de httpd. Ils n'ont pas besoin d'être chargés
	via la directive LoadModule.
    

	
    --enable-modules=MODULE-LIST
    
        
    Cette option se comporte comme
	--enable-mods-shared, et va aussi lier les modules
	concernés dynamiquement. Le mot-clé spécial none
	désactive la compilation de tous les modules.
    

        
    --enable-v4-mapped
    
        
    Permet aux sockets IPv6 de traiter les connexions IPv4.
    

        
    --with-port=PORT
    
        
    Permet de définir le port que le programme
	httpd va écouter. Ce numéro de port est
	utilisé lors de la génération du fichier de configuration
	httpd.conf. Sa valeur par défaut est 80.
    

        
    --with-program-name
    
        
    Permet de définir un nom d'exécutable alternatif. Le nom par
	défaut est httpd.
    
      
    
    
  

  
    Paquets optionnels
    
    
    Ces options permettent de définir des paquets optionnels.
    

    
    Syntaxe générale
    
      
    D'une manière générale, vous pouvez utiliser la syntaxe
      suivante pour définir un paquet optionnel :
    

      
    
        
    --with-PAQUET[=ARG]
    
        
    Utilise le paquet PAQUET. La valeur par défaut de
	ARG est yes.
    

        
    --without-PAQUET
    
        
    N'utilise pas le paquet PAQUET. Cette option est
	identique à --with-PAQUET=no. Elle est
	fournie par autoconf mais n'est pas très utile pour
	le serveur HTTP Apache.
    
      
    
    

    

    
    Paquets spécifiques
    
      
    
        
    --with-apr=REP|FICHIER
    
        
    La Bibliothèque pour la portabilité
	d'Apache ou
	Apache Portable Runtime (APR) fait partie de la
	distribution des sources de httpd et est compilée
	automatiquement avec le serveur HTTP. Si vous voulez utiliser
	une APR déjà installée à la place, vous devez indiquer à
	configure le chemin du script
	apr-config. Vous pouvez spécifier le chemin absolu
	et le nom ou le répertoire d'installation de l'APR.
	apr-config doit se trouver dans ce répertoire ou
	dans le sous-repertoire bin.
    

        
    --with-apr-util=REP|FICHIER
    
        
    Les utilitaires pour la Bibliothèque pour la portabilité
	d'Apache ou Apache Portable Runtime Utilities (APU) font partie de la
	distribution des sources de httpd et sont compilés
	automatiquement avec le serveur HTTP. Si vous voulez utiliser
	des APU déjà installés à la place, vous devez indiquer à
	configure le chemin du script
	apu-config. Vous pouvez spécifier le chemin absolu
	et le nom ou le répertoire d'installation des APU.
	apu-config doit se trouver dans ce répertoire ou
	dans le sous-repertoire bin.
    

        
    --with-ssl=REP
    
        
    Si mod_ssl a été activé,
	configure recherche une installation d'OpenSSL.
	Vous pouvez définir le répertoire de la boîte à outils SSL/TLS à
	la place.
    

        
    --with-z=REP
    
        
    configure recherche automatiquement une
	bibliothèque zlib installée si la configuration de
	vos sources en nécessite une (par exemple lorsque
	mod_deflate est activé). Vous pouvez définir le
	répertoire de la bibliothèque de compression à la place.
    
      
    

      
    De nombreuses fonctionnalités du serveur HTTP Apache, y compris
      les directives RewriteMap DBM de
      mod_rewrite et mod_authn_dbm
      utilisent une base de données simple
      de la forme clé/valeur pour une recherche rapide d'informations.
      SDBM, inclus dans les APU, est donc toujours disponible. Si vous
      souhaitez utiliser d'autres types de bases de données, utilisez
      les options suivantes afin de les activer :
    

      
    
        
    --with-gdbm[=chemin]
    
        
    Si aucun chemin n'est spécifié,
	configure va rechercher les fichiers d'en-têtes et
	les bibliothèques d'une installation DBM GNU dans les chemins
	standards. Avec un chemin explicite,
	configure recherchera les fichiers concernés dans
	chemin/lib et
	chemin/include. En fait,
	chemin permet de spécifier plusieurs chemins
	d'en-têtes et bibliothèques spécifiques en les séparant par des
	caractères ':'.
    

        
    --with-ndbm[=chemin]
    
        
    Identique à --with-gdbm, mais recherche une
	installation de New DBM.
    

        
    --with-berkeley-db[=chemin]
    
        
    Identique à --with-gdbm, mais recherche une
	installation de Berkeley DB.
    
      
    

      
    Note
    
        
    Les options DBM sont fournies par les APU et passées en
	paramètres à son script de configuration. Elles sont inutiles
	lorsqu'on utilise des APU déjà installés définis par
	--with-apr-util.
    
        
    Vous pouvez utiliser plusieurs implémentations DBM avec votre
	serveur HTTP. Le type DBM approprié sera choisi au cours de la
	configuration de l'exécution à chaque démarrage.
    
      
    
    
  

  
    Options pour les programmes de
  support
    
    
    
      
    --enable-static-support
    
      
    Permet de compiler une version des binaires de support liés
      statiquement. En d'autres termes, la compilation produira un
      exécutable indépendant comportant toutes les bibliothèques
      nécessaires. Sans cette option, les binaires de supports sont liés
      dynamiquement.
    

      
    --enable-suexec
    
      
    Utilisez cette option pour activer la programme
      suexec, qui vous permet de définir un uid et un
      gid pour les processus lancés. N'utilisez cette option que
      si vous maîtrisez toutes les implications en matière de sécurité
      de l'exécution d'un binaire suid sur votre serveur.
      D'autres options permettent de configurer
      suexec comme décrit ci-dessous.
    
    
    

    
    Il est possible de lier statiquement le binaire d'un programme
    support particulier en utilisant les options suivantes :
    

    
    
      
    --enable-static-ab
    
      
    Compile une version liée statiquement du programme
      ab.
    

      
      
    --enable-static-checkgid
    
      
    >Compile une version liée statiquement du programme
      checkgid.
    

      
    --enable-static-htdbm
    
      
    Compile une version liée statiquement du programme htdbm.
    

      
    --enable-static-htdigest
    
      
    Compile une version liée statiquement du programme htdigest.
    

      
    --enable-static-htpasswd
    
      
    Compile une version liée statiquement du programme htpasswd.
    

      
    --enable-static-logresolve
    
      
    Compile une version liée statiquement du programme logresolve.
    

      
    --enable-static-rotatelogs
    
      
    Compile une version liée statiquement du programme rotatelogs.
    
    
    

    
    Options de configuration de suexec
    
      
      
    Les options suivantes permettent de définir avec précision le
      comportement du programme suexec. Voir Configurer et installer suEXEC
	pour plus de détails.
    

      
    
        
    --with-suexec-bin
    
        
    Définit le chemin du binaire suexec. La
	valeur par défaut est --sbindir (voir Définition précise des répertoires
	d'installation).
    

        
    --with-suexec-caller
    
        
    Définit l'utilisateur qui a l'autorisation d'appeler
	suexec. Il est en général souhaitable que ce
	soit le même que celui sous lequel httpd
	s'exécute.
    

        
    --with-suexec-docroot
    
        
    Définit l'arborescence des répertoires dans laquelle le
	lancement des exécutables via suexec est
	autorisé. La valeur par défaut est
	--datadir/htdocs.
    

        
    --with-suexec-gidmin
    
        
    Définit la valeur de GID la plus basse autorisée comme
	valeur cible pour suexec. La valeur par
	défaut est 100.
    

        
    --with-suexec-logfile
    
        
    Définit le nom du fichier journal de

    --with-suexec-safepath
    
        
    Définit la valeur de la variable d'environnement
	PATH pour les processus lancés par
	suexec. La valeur par défaut est
	/usr/local/bin:/usr/bin:/bin.
    

        
    --with-suexec-userdir
    
        
    Définit le sous-répertoire du répertoire utilisateur qui
	contient tous les exécutables pouvant être lancés par
	suexec. Cette option est nécessaire si vous
	souhaitez utiliser suexec avec des
	répertoires utilisateurs (définis via
	mod_userdir). La valeur par défaut est
	public_html.
    

        
    --with-suexec-uidmin
    
        
    Définit la valeur d'UID la plus basse autorisée comme
	valeur cible pour suexec. La valeur par
	défaut est 100.
    

        
    --with-suexec-umask
    
        
    Définit le masque de permissions umask pour les
	processus lancés par suexec. Il correspond
	par défaut au masque défini par la configuration de votre
	système.

    htdigest permet de créer et maintenir les fichiers
    textes dans lesquels sont stockés des noms d'utilisateurs, des
    domaines de protection (realms) et des mots de passe pour
    l'authentification à base de condensés des utilisateurs HTTP.
    L'accès aux ressources du serveur HTTP Apache peut être limité aux
    seuls utilisateurs enregistrés dans les fichiers créés par
    htdigest.
    

    
    Cette page de manuel ne décrit que les arguments de la ligne de
    commande. Pour plus de détails à propos des directives nécessaires à
    la configuration de l'authentification à base de condensés dans
    httpd, voir le manuel Apache qui est fourni avec
    la distribution et peut être consulté à http://httpd.apache.org/.

    Considérations à propos de sécurité
    
    
    En tant qu'exécutable setuid, ce programme n'est pas sûr. En
    conséquence, évitez de lui attribuer des permissions setuid.

    Ce script perl a été conçu pour être exécuté à intervalles
    réguliers via un déclencheur de type cron. Il se connecte au serveur
    pour en extraire des informations quant à son état. Il formate ces
    informations sous la forme d'une seule ligne qu'il enregistre dans
    un fichier. Vous devez éditer la valeur des variables en tête de
    script afin de définir le chemin du fichier de sortie. Pour que ce
    script puisse fonctionner, mod_status doit au
    préalable être chargé et configuré.
    

    

    top
    

    

    Mode d'emploi
    


    Le script contient les sections suivantes :
    


    my $wherelog = "/usr/local/apache2/logs/";  # Le fichier de sortie sera
					# du style "/usr/local/apache2/logs/19960312"
my $server   = "localhost";        # Nom du serveur, par exemple "www.foo.com"
my $port     = "80";               # Port d'écoute du serveur
my $request = "/server-status/?auto";    # Requête à soumettre
    



    Ces variables doivent contenir des valeurs correctes, et le
gestionnaire /server-status doit être configuré pour le
répertoire considéré. En outre, l'utilisateur qui exécute le script doit
avoir les droits d'écriture sur le chemin du fichier de sortie.
    


    L'exécution périodique du script via cron permet d'obtenir un jeu de
rapports d'état qui pourra être utilisé à des fins d'analyse
statistique.

apxs - APache eXtenSion tool - Apache HTTP Server Version 2.4

    apxs is a tool for building and installing extension
    modules for the Apache HyperText Transfer Protocol (HTTP) server. This is
    achieved by building a dynamic shared object (DSO) from one or more source
    or object files which then can be loaded into the Apache server
    under runtime via the LoadModule
    directive from mod_so.
    

    
    So to use this extension mechanism your platform has to support the DSO
    feature and your Apache httpd binary has to be built with the
    mod_so module. The apxs tool automatically
    complains if this is not the case. You can check this yourself by manually
    running the command
    

    
    
      $ httpd -l
    
    

    
    The module mod_so should be part of the displayed list.
    If these requirements are fulfilled you can easily extend your Apache
    server's functionality by installing your own modules with the DSO mechanism
    by the help of this apxs tool:
    

    
    
      $ apxs -i -a -c mod_foo.c
    
      gcc -fpic -DSHARED_MODULE -I/path/to/apache/include -c mod_foo.c
    
      ld -Bshareable -o mod_foo.so mod_foo.o
    
      cp mod_foo.so /path/to/apache/modules/mod_foo.so
    
      chmod 755 /path/to/apache/modules/mod_foo.so
    
      [activating module `foo' in /path/to/apache/etc/httpd.conf]
    
      $ apachectl restart
    
      /path/to/apache/sbin/apachectl restart: httpd not running, trying to start
    
      [Tue Mar 31 11:27:55 1998] [debug] mod_so.c(303): loaded module foo_module
    
      /path/to/apache/sbin/apachectl restart: httpd started
    
      $ _
    
    

    
    The arguments files can be any C source file (.c), a object
    file (.o) or even a library archive (.a). The apxs tool
    automatically recognizes these extensions and  automatically used the C
    source files for compilation while just using the object and archive files
    for the linking phase. But when using such pre-compiled objects make sure
    they are compiled for position independent code (PIC) to be able to use them
    for a dynamically loaded shared object. For instance with GCC you always
    just have to use -fpic. For other C compilers consult its
    manual page or at watch for the flags apxs uses to compile the
    object files.
    

    
    For more details about DSO support in Apache read the documentation of
    mod_so or perhaps even read the
    src/modules/standard/mod_so.c source file.

    Options
    
    
    Common Options
    
      
    
      
    -n modname
    
      
    This explicitly sets the module name for the -i (install)
      and -g (template generation) option. Use this to explicitly
      specify the module name. For option -g this is required, for
      option -i the apxs tool tries to determine the
      name from the source or (as a fallback) at least by guessing it from the
      filename.
    
      
    
    

    
    Query Options
    
      
    
      
    -q
    
      
    Performs a query for variables and environment settings used to
      build httpd.  When invoked without query parameters,
      it prints all known variables and their values.  The optional -v
      parameter formats the list output.

      
    Use this to manually determine settings used to build the
      httpd that will load your module.  For instance use
    
      
    
        INC=-I`apxs -q INCLUDEDIR`
      
    

      
    inside your own Makefiles if you need manual access to Apache's C
      header files.
    
      
    
    

    
    Configuration Options
    
      
    
      
    -S name=value
    
      
    This option changes the apxs settings described above.
    
      
    
    

    
    Template Generation Options
    
      
    
      
    -g
    
      
    This generates a subdirectory name (see option
      -n) and there two files: A sample module source file named
      mod_name.c which can be used as a template for
      creating your own modules or as a quick start for playing with the
      apxs mechanism. And a corresponding Makefile for even easier
      build and installing of this module.
    
      
    
    

    
    DSO Compilation Options
    
      
    
      
    -c
    
      
    This indicates the compilation operation. It first compiles the C
      source files (.c) of files into corresponding object files (.o)
      and then builds a dynamically shared object in dsofile by
      linking these object files plus the remaining object files (.o and .a) of
      files. If no -o option is specified the output
      file is guessed from the first filename in files and thus
      usually defaults to mod_name.so.
    

      
    -o dsofile
    
      
    Explicitly specifies the filename of the created dynamically shared
      object. If not specified and the name cannot be guessed from the
      files list, the fallback name mod_unknown.so is
      used.
    

      
    -D name=value
    
      
    This option is directly passed through to the compilation command(s).
      Use this to add your own defines to the build process.
    

      
    -I incdir
    
      
    This option is directly passed through to the compilation command(s).
      Use this to add your own include directories to search to the build
      process.
    

      
    -L libdir
    
      
    This option is directly passed through to the linker command. Use this
      to add your own library directories to search to the build  process.
    

      
    -l libname
    
      
    This option is directly passed through to the linker command. Use this
      to add your own libraries to search to the build process.
    

      
    -Wc,compiler-flags
    
      
    This option passes compiler-flags as additional flags to
      the libtool --mode=compile command. Use this to add local
      compiler-specific options.
    

      
    -Wl,linker-flags
    
      
    This option passes linker-flags as additional
      flags to the libtool --mode=link command. Use this
      to add local linker-specific options.
    

      
    -p
    
      
    This option causes apxs to link against the apr/apr-util libraries.
      This is useful when compiling helper programs that use the apr/apr-util
      libraries.
    
      
    
    

    
    DSO Installation and Configuration Options
    
    
      
    
      
    -i
    
      
    This indicates the installation operation and installs one or more
      dynamically shared objects into the server's modules
      directory.
    

      
    -a
    
      
    This activates the module by automatically adding a corresponding
      LoadModule line to Apache's
      httpd.conf configuration file, or by enabling it if it
      already exists.
    

      
    -A
    
      
    Same as option -a but the created LoadModule directive is prefixed with a hash
      sign (#), i.e., the module is just prepared for
      later activation but initially disabled.
    

      
    -e
    
      
    This indicates the editing operation, which can be used with the
      -a and -A options similarly to the
      -i operation to edit Apache's httpd.conf
      configuration file without attempting to install the module.
    
      
    
    

    top
    

    

    Examples
    
    
    Assume you have an Apache module named mod_foo.c available
    which should extend Apache's server functionality. To accomplish this you
    first have to compile the C source into a shared object suitable for loading
    into the Apache server under runtime via the following command:
    

    
    
      $ apxs -c mod_foo.c
    
      /path/to/libtool --mode=compile gcc ... -c mod_foo.c
    
      /path/to/libtool --mode=link gcc ... -o mod_foo.la mod_foo.slo
    
      $ _
    
    

    
    Then you have to update the Apache configuration by making sure a
    LoadModule directive is present to
    load this shared object. To simplify this step apxs provides
    an automatic way to install the shared object in its "modules" directory
    and updating the httpd.conf file accordingly. This can be
    achieved by running:
    

    
    
      $ apxs -i -a mod_foo.la
    
      /path/to/instdso.sh mod_foo.la /path/to/apache/modules
    
      /path/to/libtool --mode=install cp mod_foo.la /path/to/apache/modules
      ...
      chmod 755 /path/to/apache/modules/mod_foo.so
    
      [activating module `foo' in /path/to/apache/conf/httpd.conf]
    
      $ _
    
    

    
    This way a line named
    

    
    
      LoadModule foo_module modules/mod_foo.so
    
    

    
    is added to the configuration file if still not present. If you want to
    have this disabled per default use the -A option,
    i.e.
    

    
    
      $ apxs -i -A mod_foo.c
    
    

    
    For a quick test of the apxs mechanism you can create a sample Apache
    module template plus a corresponding Makefile via:
    

    
    
      $ apxs -g -n foo
    
      Creating [DIR]  foo
    
      Creating [FILE] foo/Makefile
    
      Creating [FILE] foo/modules.mk
    
      Creating [FILE] foo/mod_foo.c
    
      Creating [FILE] foo/.deps
    
      $ _
    
    

    
    Then you can immediately compile this sample module into a shared object
    and load it into the Apache server:
    

    
    
      $ cd foo
    
      $ make all reload
    
      apxs -c mod_foo.c
    
      /path/to/libtool --mode=compile gcc ... -c mod_foo.c
    
      /path/to/libtool --mode=link gcc ... -o mod_foo.la mod_foo.slo
    
      apxs -i -a -n "foo" mod_foo.la
    
      /path/to/instdso.sh mod_foo.la /path/to/apache/modules
    
      /path/to/libtool --mode=install cp mod_foo.la /path/to/apache/modules
      ...
      chmod 755 /path/to/apache/modules/mod_foo.so
    
      [activating module `foo' in /path/to/apache/conf/httpd.conf]
    
      apachectl restart
    
      /path/to/apache/sbin/apachectl restart: httpd not running, trying to start

    dbmmanage permet de créer et de maintenir les
    fichiers au format DBM où sont stockés les noms d'utilisateurs et
    mots de passe à des fins d'authentification de base des utilisateurs
    HTTP via le module mod_authn_dbm. Il est possible
    de restreindre l'accès aux ressources disponibles sur le serveur
    HTTP Apache aux seuls utilisateurs spécifiés dans les fichiers créés
    par dbmmanage. Ce programme ne peut être utilisé
    qu'avec des fichiers d'utilisateurs au format DBM. Pour
    l'utilisation de fichiers textes, voir le programme
    htpasswd.
    

    
    Le programme htdbm est aussi un utilitaire
    permettant de maintenir une base de données de mots de passe DBM.
    

    
    Cette page de manuel ne décrit que les arguments de la ligne de
    commande. Pour plus de détails à propos des directives nécessaires
    pour configurer l'authentification des utilisateurs dans
    httpd, voir le manuel httpd qui est fourni avec
    la distribution d'Apache, ou peut être consulté à http://httpd.apache.org/.

    Options
    
    
    
    
    nom-fichier
    
    
    Le nom du fichier au format DBM, en général sans l'extension
    .db, .pag, ou .dir.
    

    
    nom-utilisateur
    
    
    L'utilisateur concerné par l'opération effectuée. Le
    nom-utilisateur ne doit pas contenir de caractère

    mot-de-passe-chiffré
    
    
    C'est le mot de passe sous sa forme chiffrée à utiliser avec les
    commandes update et add. Vous pouvez
    utiliser un tiret (-) si vous voulez que le mot de
    passe vous soit demandé, mais remplissez les champs par la suite. En
    outre, avec la commande update, un point
    (.) permet de conserver le mot de passe original.
    

    
    groupe
    
    
    Un groupe dont l'utilisateur est membre. Un nom de groupe ne
    doit pas contenir de caractère (:). Vous pouvez
    utiliser un tiret (-) si vous ne voulez pas associer
    l'utilisateur à un groupe, mais remplissez le champ commentaire. En
    outre, avec la commande update, un point
    (.) permet de conserver le groupe original.
    

    
    commentaire
    
    
    C'est l'endroit où vous pouvez enregistrer diverses informations
    à propos de l'utilisateur telles que son nom réel, sont e-mail,
    etc... Le serveur ignore ce champ.

    import
    
      
    Lit les entrées
      nom-utilisateur:mot-de-passe
      (une par ligne) depuis STDIN, et les ajoute à
      nom-fichier. Les mots de passe doivent être déjà
      chiffrés.
    

      
    update
    
      
    Identique à la commande adduser, à l'exception
      que la présence de nom-utilisateur dans
      nom-fichier est vérifiée.

      
    dbmmanage passwords.dat update rbowen
    
      
    

      
    view
    
      
    Affiche le contenu du fichier DBM. Si vous spécifiez un
      nom-utilisateur, seule l'entrée correspondante est
      affichée.

      
    dbmmanage passwords.dat view
    
      
    
      
    
    

    top
    

    

    Bogues
    
    
    Vous devez garder à l'esprit qu'il existe de nombreux formats de
    fichiers DBM différents, et que selon toute vraisemblance, des
    bibliothèques pour plus d'un format sont présentes sur votre
    système. Les trois exemples de base sont SDBM, NDBM, le projet GNU
    GDBM, et Berkeley DB 2. Malheureusement, toutes ces bibliothèques
    utilisent des formats de fichiers différents, et vous devez vous
    assurer que le format de fichier utilisé par nom-fichier
    correspond au format attendu par dbmmanage.
    Actuellement, dbmmanage n'a aucun moyen de savoir à
    quel type de fichier DBM il a à faire. S'il est utilisé avec un
    format inapproprié, il ne renverra rien, ou pourra créer un fichier
    DBM différent avec un nom différent, ou au pire, va corrompre le
    fichier DBM si vous avez tenté de le modifier.
    

    
    dbmmanage possède une liste de préférences en
    matière de formats DBM, définies dans le tableau
    @AnyDBM::ISA au début du programme. Comme nous
    préférons le format de fichier Berkeley DB 2, l'ordre dans lequel
    dbmmanage va rechercher les bibliothèques système est
    Berkeley DB 2, puis NDBM, GDBM et enfin SDBM. La première
    bibliothèque trouvée sera celle que dbmmanage tentera
    d'utiliser pour toutes les opérations sur les fichiers DBM. Cette
    ordre est sensiblement différent de l'ordre standard de Perl
    @AnyDBM::ISA, et de l'ordre utilisé par l'appel
    dbmopen() de Perl ; si vous utilisez un autre
    utilitaire pour gérer vos fichiers DBM, il doit donc se conformer à
    l'ordre de préférence indiqué précédemment. Vous devez prêter la
    même attention si vous utilisez des programmes écrits dans d'autres
    langages, comme C, pour accéder à ces fichiers.
    

    
    Vous pouvez utiliser le programme file fourni par la
    plupart des systèmes Unix pour déterminer le format d'un fichier
    DBM.

    htpasswd permet de créer et de maintenir les
    fichiers textes où sont stockés les noms d'utilisateurs et mots de
    passe pour l'authentification de base des utilisateurs HTTP. Si
    htpasswd rencontre un problème d'accès à un fichier,
    que ce soit pour écrire dans le fichier de sortie, ou pour lire le
    fichier d'entrée dans le but de le mettre à jour, il renvoie un code
    d'erreur et n'effectue aucune modification.
    

    
    Il est possible de limiter l'accès aux ressources du serveur HTTP
    Apache aux seuls utilisateurs présents dans les fichiers créés par
    htpasswd. Ce programme ne sait gérer les noms
    d'utilisateurs et mots de passe que s'ils sont stockés dans des
    fichiers textes. Il peut cependant chiffrer et afficher les mots de
    passe à des fins d'utilisation dans d'autres types de bases de
    données. Pour utiliser une base de données DBM, voir le programme
    dbmmanage ou htdbm.
    

    
    htpasswd chiffre les mots de passe en utilisant soit
    bcrypt,
    une version de MD5 modifiée pour Apache, soit SHA1, soit la routine
    crypt() du système. Les fichiers gérés par
    htpasswd peuvent contenir deux types de mots de passe ;
    certaines entrées peuvent contenir des mots de passe chiffrés en
    MD5 ou bcrypt, alors que d'autres entrées du même fichier contiendront des
    mots de passe chiffrés avec crypt().
    

    
    Cette page de manuel ne décrit que les arguments de la ligne de
    commande. Pour plus de détails à propos des directives nécessaires à
    la configuration de l'authentification des utilisateurs dans
    httpd, voir le manuel Apache qui est fourni avec
    la distribution ou peut être consulté à http://httpd.apache.org/.

    Options
    
    
    
    
    -b
    
    
    Utilise le mode batch ; c'est à dire, extrait le mot de passe de
    la ligne de commande au lieu de le demander à l'opérateur. Cette
    option doit être utilisée avec la plus grande prudence, car
    le mot de passe est visible en clair dans la ligne
    de commande. Pour utiliser un script, voir l'option
    -i.
    Disponible à partir de la version 2.4.4 du serveur HTTP Apache.
    

    
    -i
    
    
    Lit le mot de passe depuis stdin sans vérification (à utiliser
    dans les scripts).
    

    
    -c
    
    
    Crée le fichier-mots-de-passe. Si
    fichier-mots-de-passe existe déjà, il est réécrit et
    tronqué. Cette option ne peut pas être combinée avec l'option
    -n.
    

    
    -n
    
    
    Affiche le résultat du traitement sur la sortie standard au lieu
    de mettre à jour le fichier. Ceci peut s'avérer utile pour générer
    des enregistrements de mots de passe qu'Apache pourra utiliser à des
    fins d'inclusion dans des fichiers de données au format autre que
    texte. Cette option modifie la syntaxe de la ligne de commande, car
    l'argument fichier-mots-de-passe (en général le premier)
    est omis. Elle ne peut pas être combinée avec l'option
    -c option.
    

    
    -m
    
    
    Utilise le chiffrement MD5 pour les mots de passe. C'est le
    comportement par défaut (depuis la version 2.2.18).
    

    
    -B
    
    
    Utilise bcrypt pour chiffrer les mots de passe. c'est un
    algorythme de chiffrement actuellement considéré comme sûr.
    

    
    -C
    
    
    Ce drapeau n'est autorisé qu'en conjonction avec le drapeau
    -B (chiffrement bcrypt). Il permet de définir la durée
    de traitement pour l'algorytme bcrypt (plus elle est longue,
    meilleure sera la sécurité, mais inférieure la rapidité). La valeur
    par défaut est 5 et les valeurs autorisées vont de 4 à 17.
    


    
    -d
    
    
    Utilise le chiffrement crypt() pour les mots de
    passe. Cette option n'est pas supportée par le
    serveur httpd sous Windows ou Netware. Cet
    algorithme limite la longueur des mots de passe à 8 caractères ; il
    est considéré comme non sur du point de vue des
    standards actuels. C'était l'algorithme par défaut jusqu'à la
    version 2.2.17.
    

    
    -s
    
    
    Utilise le chiffrement SHA pour les mots de passe. Facilite la
    migration vers/depuis les serveurs Netscape qui utilisent le format
    LDAP Directory Interchange (ldif). Cet algorithme
    est considéré comme non sur du point de vue des
    standards actuels.
    

    
    -p
    
    
    Enregistre les mots de passe en clair. Bien que
    htpasswd supporte la création des mots de passe en
    clair sur toutes les plates-formes, le démon
    httpd n'accepte les mots de passe en clair que
    sous Windows et Netware.
    

    
    -D
    
    
    Supprime un utilisateur, sous réserve qu'il existe dans le
    fichier spécifié par htpasswd.
    

    
    -v
    
    
    Vérifie si le mot de passe fourni correspond au mot de passe de
    l'utilisateur enregistré dans le fichier de mots de passe spécifié.
    Disponible à partir de la version 2.4.5 du serveur HTTP Apache.
    

    
    fichier-mots-de-passe
    
    
    Le nom du fichier contenant les noms d'utilisateurs et mots de
    passe. Avec l'option -c, le fichier est créé s'il
    n'existe pas, ou réécrit et tronqué s'il existe déjà.
    

    
    nom-utilisateur
    
    
    Le nom d'utilisateur à créer ou mettre à jour dans le
    fichier-mots-de-passe. Si nom-utilisateur
    n'existe pas, une nouvelle entrée est ajoutée. Dans le cas
    contraire, le mot de passe est modifié.
    

    
    mot-de-passe
    
    
    Le mot de passe en clair et destiné à être chiffré puis stocké
    dans le fichier. Cet argument ne s'utilise qu'avec l'option
    -b.
    
    
    

    top
    

    

    Valeur renvoyée
    
    
    htpasswd renvoie 0 ("true") si le nom d'utilisateur
    et le mot de passe ont été enregistrés ou mis à jour avec succès
    dans le fichier-mots-de-passe. htpasswd
    renvoie 1 s'il a rencontré un problème d'accès aux
    fichiers, 2 si la ligne de commande comportait une
    erreur de syntaxe, 3 si le mot de passe entré
    interactivement ne correspondait pas au nom d'utilisateur,
    4 si l'opération a été interrompue, 5 si
    une valeur était trop longue (nom-utilisateur, nom-fichier,
    mot-de-passe, ou l'enregistrement résultant), 6 si le
    nom d'utilisateur contenait des caractères illégaux (voir la section
    Restrictions), et 7 si le
    fichier spécifié n'était pas un fichier de mots de passe
    valide.
    

    top
    

    

    Exemples
    
    
    
      htpasswd /usr/local/etc/apache/.utilisateurs-htpasswd jsmith
    
    

    
    Ajoute ou modifie le mot de passe de l'utilisateur
    jsmith. Le mot de passe est demandé à l'opérateur. Le
    mot de passe sera chiffré en utilisant l'algorithme MD5
    modifié pour Apache. Si le fichier spécifié
    n'existe pas, htpasswd renverra un code d'erreur.

    Crée un nouveau fichier de mots de passe et y enregistre une
    entrée pour l'utilisateur jane. Le mot de passe est
    demandé à l'opérateur. Si le fichier existe et ne peut être ni lu ni
    écrit, il n'est pas modifié et htpasswd affichera un
    message et renverra un code d'erreur.
    

    
    
      htpasswd -db /usr/web/.htpasswd-tous jones Pwd4Steve
    
    

    
    Chiffre le mot de passe spécifié dans la ligne de commande
    (Pwd4Steve) en utilisant l'algorithme
    crypt(), et le stocke dans le fichier spécifié.

    Considérations à propos de sécurité
    
    
    Les fichiers de mots de passe Web comme ceux que gère
    htpasswd ne doivent pas être situés dans
    l'espace d'URI du serveur Web -- en d'autres termes, il ne doit pas
    être possible d'y accéder à partir d'un navigateur.
    

    
    En tant qu'exécutable setuid, ce programme n'est pas sûr, et il
    ne faut par conséquent pas lui attribuer de permissions
    setuid.
    

    
    L'utilisation de l'option -b est déconseillée, car
    avec elle, les mots de passe apparaissent en clair dans la ligne de
    commande.
    

    
    Notez qu'avec l'algorithme crypt(), seuls les huit
    premiers caractères du mot de passe spécifié sont pris en compte. Si
    le mot de passe spécifié est plus long, les caractères
    supplémentaires sont ignorés.
    

    
    Le format de chiffrement SHA n'utilise pas d'amorçage aléatoire
    (salting) : à un mot de passe donné correspond une seule
    représentation chiffrée. Les formats crypt() et MD5
    permutent la représentation en la préfixant par une chaîne d'amorce
    aléatoire, afin de rendre les attaques de mots de passe à base de
    dictionnaires plus difficiles.
    

    
    Les algorithmes de chiffrement SHA et crypt() 
    sont considérés comme non surs du point de vue des
    standards actuels.
    

    top
    

    

    Restrictions
    
    
    Sur les plates-formes Windows, la taille des mots de passe
    chiffrés avec htpasswd est limitée à 255
    caractères. Les mots de passe dont la taille est supérieure seront
    tronqués.
    

    
    L'algorithme MD5 utilisé par htpasswd est spécifique
    à Apache ; les mots de passe chiffrés en utilisant cet algorithme
    seront inutilisables sur d'autres serveurs Web.
    

    
    La taille des noms d'utilisateurs est limitée à 255
    octets et ceux-ci ne doivent pas contenir de caractère
    :.
    

    
    Le coût en performances de la génération de la valeur de hashage d'un mot
    de passe bcrypt augmente avec le nombre de passes spécifié par l'option
    -C. A partir de sa version 1.6.0, la bibliothèque
    apr-util limite le nombre de passes à 17.

    The configure script configures the source tree
    for compiling and installing the Apache HTTP Server on your
    particular platform. Various options allow the compilation of a
    server corresponding to your personal requirements.
    

    
    This script, included in the root directory of the source
    distribution, is for compilation on Unix and Unix-like systems
    only. For other platforms, see the platform documentation.

    Synopsis
    
    
    You should call the configure script from within the
    root directory of the distribution.
    

    
    ./configure [OPTION]...
    [VAR=VALUE]...
    

    
    To assign environment variables (e.g. CC,
    CFLAGS ...), specify them as
    VAR=VALUE. See below
    for descriptions of some of the useful variables.

    Options
    
  

  
    Configuration options
    

    
    The following options influence the behavior of
    configure itself.
    

    
    
      
    -C
    
      
    --config-cache
    
      
    This is an alias for --cache-file=config.cache
    

      
    --cache-file=FILE
    
      
    The test results will be cached in file FILE.
        This option is disabled by default.
    

      
    -h
    
      
    --help [short|recursive]
    
      
    Output the help and exit. With the argument short only
        options specific to this package will displayed. The argument
        recursive displays the short help of all the included
        packages.
    

      
    -n
    
      
    --no-create
    
      
    The configure script is run normally but does
        not create output files. This is useful to check the test results
        before generating makefiles for compilation.
    

      
    -q
    
      
    --quiet
    
      
    Do not print checking ... messages during the
        configure process.
    

      
    --srcdir=DIR
    
      
    Defines directory DIR to be the source file directory.
        Default is the directory where configure is located, or
        the parent directory.
    

      
    --silent
    
      
    Same as --quiet
    

      
    -V
    
      
    --version
    
      
    Display copyright information and exit.
    
    
    
  

  
    Installation
    directories
    

    
    These options define the installation directory. The installation
      tree depends on the selected layout.
    

    
    
      
    --prefix=PREFIX
    
      
    Install architecture-independent files in PREFIX.
        By default the installation directory is set to
        /usr/local/apache2.
    

      
    --exec-prefix=EPREFIX
    
      
    Install architecture-dependent files in EPREFIX.
        By default the installation directory is set to the
        PREFIX directory.
    
    
    

    
    By default, make install will install all the files in
      /usr/local/apache2/bin, /usr/local/apache2/lib
      etc. You can specify an installation prefix other than
      /usr/local/apache2 using --prefix,
      for instance --prefix=$HOME.
    

    
    Define a directory layout
    
      
    
        
    --enable-layout=LAYOUT
    
        
    Configure the source code and build scripts to assume an
          installation tree based on the layout LAYOUT. This allows
          you to separately specify the locations for each type of file within
          the Apache HTTP Server installation. The config.layout
          file contains several example configurations, and you can also create
          your own custom configuration following the examples. The different
          layouts in this file are grouped into <Layout
            FOO>...</Layout> sections and referred to by name as
          in FOO. The default layout is Apache.
    
      
    
    

    
    Fine tuning of the installation
      directories
    

      
    For better control of the installation directories, use the options
        below. Please note that the directory defaults are set by
        autoconf and are overwritten by the corresponding layout
        setting.
    

      
    
        
        
    --bindir=DIR
    
        
    Install user executables in DIR. The user executables
          are supporting programs like htpasswd,
          dbmmanage, etc. which are useful for site
          administrators. By default DIR is set to
          EPREFIX/bin.
    

        
    --datadir=DIR
    
        
    Install read-only architecture-independent data in DIR.
          By default datadir is set to
          PREFIX/share. This option is offered by
          autoconf and currently unused.
    

        
    --includedir=DIR
    
        
    Install C header files in DIR. By default
          includedir is set to
          EPREFIX/include.
    

        
    --infodir=DIR
    
        
    Install info documentation in DIR.
          By default infodir is set to
          PREFIX/info. This option is currently
          unused.
    

        
    --libdir=DIR
    
        
    Install object code libraries in DIR. By default
          libdir is set to
          EPREFIX/lib.
    

        
    --libexecdir=DIR
    
        
    Install the program executables (i.e., shared modules) in
          DIR. By default libexecdir is set to
          EPREFIX/modules.
    

        
    --localstatedir=DIR
    
        
    Install modifiable single-machine data in DIR.
          By default localstatedir is set to
          PREFIX/var. This option is offered by
          autoconf and currently unused.
    

        
    --mandir=DIR
    
        
    Install the man documentation in DIR. By default
          mandir is set to
          EPREFIX/man.
    

        
    --oldincludedir=DIR
    
        
    Install C header files for non-gcc in DIR.
          By default oldincludedir is set to
          /usr/include. This option is offered by
          autoconf and currently unused.
    

        
    --sbindir=DIR
    
        
    Install the system administrator executables in DIR.
          Those are server programs like httpd,
          apachectl, suexec, etc. which
          are necessary to run the Apache HTTP Server. By default
          sbindir is set to
          EPREFIX/sbin.
    

        
    --sharedstatedir=DIR
    
        
    Install modifiable architecture-independent data in DIR.
          By default sharedstatedir is set to
          PREFIX/com. This option is offered by
          autoconf and currently unused.
    

        
    --sysconfdir=DIR
    
        
    Install read-only single-machine data like the server configuration
          files httpd.conf, mime.types, etc. in
          DIR. By default sysconfdir is set to
          PREFIX/conf.
    
      
    
    
  

  
    System types
    

    
    These options are used to cross-compile the Apache HTTP Server to run on
      another system. In normal cases, when building and running the server on
      the same system, these options are not used.
    

    
    
      
    --build=BUILD
    
      
    Defines the system type of the system on which the tools are being
        built. It defaults to the result of the script
        config.guess.
    

      
    --host=HOST
    
      
    Defines the system type of the system on which the server will run.
        HOST defaults to BUILD.
    

      
    --target=TARGET
    
      
    Configure for building compilers for the system type
        TARGET. It defaults to HOST. This option is
        offered by autoconf and not necessary for the Apache HTTP
        Server.
    
    
    
  

  
    Optional Features
    

    
    These options are used to fine tune the features your HTTP server will
      have.
    

    
    General syntax
    
      
    Generally you can use the following syntax to enable or disable a
        feature:
    

      
    
        
    --disable-FEATURE
    
        
    Do not include FEATURE. This is the same as
          --enable-FEATURE=no.
    

        
    --enable-FEATURE[=ARG]
    
        
    Include FEATURE. The default value for ARG
          is yes.
    

        
    --enable-MODULE=shared
    
        
    The corresponding module will be built as a DSO module.
            By default enabled modules are linked dynamically.
    

        
    --enable-MODULE=static
    
        
    The corresponding module will be linked statically.
    
      
    

      
    Note
    
        configure will not complain about
        --enable-foo even if foo doesn't
        exist, so you need to type carefully.
      
    
    

    
    Choosing modules to compile
    
      
    Most modules are compiled by default and have to be disabled
        explicitly or by using the keyword few 
        (see --enable-modules, --enable-mods-shared
        and --enable-mods-static below for further explanation)
        or --enable-modules=none to be removed as a group.
    

        
    Other modules are not compiled by default and have to be enabled
        explicitly or by using the keywords all or
        reallyall to be available.
    

        
    To find out which modules are compiled by default, run
        ./configure -h or ./configure --help
        and look under Optional Features.  Suppose you
        are interested in mod_example1 and
        mod_example2, and you
        see this:
    

        
    Optional Features:
  ...
  --disable-example1     example module 1
  --enable-example2      example module 2
  ...
    

        
    Then mod_example1 is enabled by default,
        and you would use --disable-example1 to not
        compile it.  mod_example2 is disabled by
        default, and you would use --enable-example2
        to compile it.
    
    

    
    Multi-Processing Modules
    
      
    Multi-Processing Modules, or MPMs, implement
        the basic behavior of the server.  A single MPM must be active in order
        for the server to function.  The list of available MPMs appears on the
        module index page.
    

      
    MPMs can be built as DSOs for dynamic loading or statically linked with
        the server, and are enabled using the following options:
    

      
    
        
    --with-mpm=MPM
    
        
    
          
    Choose the default MPM for your server.  If MPMs are built as DSO
            modules (see --enable-mpms-shared), this directive
            selects the MPM which will be loaded in the default configuration
            file.  Otherwise, this directive selects the only available MPM,
            which will be statically linked into the server.
    
          
    If this option is omitted, the default
          MPM for your operating system will be used.
    
        
    

        
    --enable-mpms-shared=MPM-LIST
    
        
    
          
    Enable a list of MPMs as dynamic shared modules.  One of these
            modules must be loaded dynamically using the
            LoadModule directive.
    
          
    MPM-LIST is a space-separated list of MPM names
            enclosed by quotation marks.  For example:
    
          
    
            --enable-mpms-shared='prefork worker'
          
    
          
    Additionally you can use the special keyword all,
            which will select all MPMs which support dynamic loading on the
            current platform and build them as DSO modules.  For example:
    
          
    
            --enable-mpms-shared=all
          
    
	
    
      
    
    

    
    Third-party modules
    
      
    To add additional third-party modules use the following options:
    

      
    
        
    --with-module=module-type:module-file[,
          module-type:module-file]
    
        
    Add one or more third-party modules to the list of statically linked
            modules. The module source file module-file
            will be searched in the modules/module-type
            subdirectory of your Apache HTTP server source tree. If it is not found
            there configure is considering module-file to be
            an absolute file path and tries to copy the source file into the
            module-type subdirectory. If the subdirectory doesn't
            exist it will be created and populated with a standard
            Makefile.in.
    
          
    This option is useful to add small external modules consisting of
            one source file. For more complex modules you should read the
            vendor's documentation.
    
          
    Note
    
            If you want to build a DSO module instead of a statically linked
            use apxs.
    
        
    
      
    
    

    
    Cumulative and other options
    
      
    
        
    --enable-maintainer-mode
    
        
    Turn on debugging and compile time warnings
            and load all compiled modules.
    

        
    --enable-mods-shared=MODULE-LIST
    
        
    
          
    Defines a list of modules to be enabled and build as dynamic
            shared modules. This mean, these module have to be loaded
            dynamically by using the  LoadModule directive.
    
          
    MODULE-LIST is a space separated list of modulenames
            enclosed by quotation marks. The module names are given without the
            preceding mod_. For example:
    
          
    
            --enable-mods-shared='headers rewrite dav'
          
    
          
    Additionally you can use the special keywords reallyall,
            all, most and few.
            For example,
    
          
    
            --enable-mods-shared=most
          
    
          
    will compile most modules and build them as DSO modules,
    
          
    
            --enable-mods-shared=few
          
    
          
    will only compile a very basic set of modules.
    
          
    The default set is most.
    
            
          
    The LoadModule directives for
          the chosen modules will be automatically generated in the main
          configuration file. By default, all those directives will be commented
          out except for the modules that are either required or explicitly selected
          by a configure --enable-foo argument. You can change the set
          of loaded modules by activating or deactivating the LoadModule directives in
          httpd.conf. In addition the
          LoadModule directives for all
          built modules can be activated via the configure option
          --enable-load-all-modules.
    
        
    

        
    --enable-mods-static=MODULE-LIST
    
        
    This option behaves similar to --enable-mods-shared,
          but will link the given modules statically. This mean, these modules
          will always be present while running httpd. They need
          not be loaded with LoadModule.
    

        
    --enable-modules=MODULE-LIST
    
        
    This option behaves like to --enable-mods-shared,
          and will also link the given modules dynamically. The special
          keyword none disables the build of all modules.
    

        
    --enable-v4-mapped
    
        
    Allow IPv6 sockets to handle IPv4 connections.
    

        
    --with-port=PORT
    
        
    This defines the port on which httpd will listen.
          This port number is used when generating the configuration file
          httpd.conf. The default is 80.
    

        
    --with-program-name
    
        
    Define an alternative executable name. The default is
          httpd.
    
      
    
    
  

  
    Optional packages
    
    
    These options are used to define optional packages.
    

    
    General syntax
    
      
    Generally you can use the following syntax to define an optional
        package:
    

      
    
        
    --with-PACKAGE[=ARG]
    
        
    Use the package PACKAGE. The default value for
          ARG is yes.
    

        
    --without-PACKAGE
    
        
    Do not use the package PACKAGE. This is the same as
          --with-PACKAGE=no. This option is provided by
          autoconf but not very useful for the Apache HTTP
          Server.
    
      
    
    

    

    
    Specific packages
    
      
    
        
    --with-apr=DIR|FILE
    
        
    The Apache Portable Runtime (APR)
          is part of the httpd
          source distribution and will automatically be build together with the
          HTTP server. If you want to use an already installed APR instead you
          have to tell configure the path to the
          apr-config script. You may set the absolute path and name
          or the directory to the installed APR. apr-config must
          exist within this directory or the subdirectory
          bin.
    

        
    --with-apr-util=DIR|FILE
    
        
    The Apache Portable Runtime Utilities (APU) are part of the
          httpd source distribution and will automatically be build
          together with the HTTP server. If you want to use an already installed
          APU instead you have to tell configure the path to the
          apu-config script. You may set the absolute path and name
          or the directory to the installed APU. apu-config must
          exist within this directory or the subdirectory
          bin.
    

        
    --with-ssl=DIR
    
        
    If mod_ssl has been enabled configure
          searches for an installed OpenSSL. You can set the directory path
          to the SSL/TLS toolkit instead.
    

        
    --with-z=DIR
    
        
    configure searches automatically for an installed
          zlib library if your source configuration requires one
          (e.g., when mod_deflate is enabled). You can set the
          directory path to the compression library instead.
    
      
    

      
    Several features of the Apache HTTP Server, including
        mod_authn_dbm and mod_rewrite's DBM
        RewriteMap use simple
        key/value databases for quick lookups of information. SDBM is included
        in the APU, so this database is always available. If you would like to
        use other database types, use the following options to enable
        them:
    

      
    
        
    --with-gdbm[=path]
    
        
    If no path is specified, configure will
          search for the include files and libraries of a GNU DBM
          installation in the usual search paths. An explicit
          path will cause configure to look in
          path/lib and
          path/include for the relevant files.
          Finally, the path may specify specific include and
          library paths separated by a colon.
    

        
    --with-ndbm[=path]
    
        
    Like --with-gdbm, but searches for a New DBM
          installation.
    

        
    --with-berkeley-db[=path]
    
        
    Like --with-gdbm, but searches for a Berkeley DB
          installation.
    
      
    

      
    Note
    
        
    The DBM options are provided by the APU and passed through to its
          configuration script. They are useless when using an already
          installed APU defined by --with-apr-util.
    
        
    You may use more then one DBM implementation together with your
          HTTP server. The appropriated DBM type will be configured within
          the runtime configuration at each time.
    
      
    
    
  

  
    Options for support programs
    
    
    
      
    --enable-static-support
    
      
    Build a statically linked version of the support binaries. This
        means, a stand-alone executable will be built with all the necessary
        libraries integrated. Otherwise the support binaries are linked
        dynamically by default.
    

      
    --enable-suexec
    
      
    Use this option to enable suexec, which allows you to set
        uid and gid for spawned processes. Do not use this
        option unless you understand all the security implications of
        running a suid binary on your server. Further options
        to configure suexec are described below.
    
    
    

    
    It is possible to create a statically linked binary of a single
      support program by using the following options:
    

    
    
      
    --enable-static-ab
    
      
    Build a statically linked version of ab.
    

      
      
    --enable-static-checkgid
    
      
    Build a statically linked version of checkgid.
    

      
    --enable-static-htdbm
    
      
    Build a statically linked version of htdbm.
    

      
    --enable-static-htdigest
    
      
    Build a statically linked version of htdigest.
    

      
    --enable-static-htpasswd
    
      
    Build a statically linked version of htpasswd.
    

      
    --enable-static-logresolve
    
      
    Build a statically linked version of logresolve.
    

      
    --enable-static-rotatelogs
    
      
    Build a statically linked version of rotatelogs.
    
    
    

    
    suexec configuration options
    
      
      
    The following options are used to fine tune the behavior of suexec. See Configuring and installing suEXEC
        for further information.
    

      
    
        
    --with-suexec-bin
    
        
    This defines the path to suexec binary.
        Default is --sbindir (see Fine tuning of installation directories).
    

        
    --with-suexec-caller
    
        
    This defines the user allowed to call suexec.
          It should be the same as the user under which
          httpd normally runs.
    

        
    --with-suexec-docroot
    
        
    This defines the directory tree under which suexec access is allowed for executables. Default value is
          --datadir/htdocs.
    

        
    --with-suexec-gidmin
    
        
    Define this as the lowest GID allowed to be a target user for
          suexec. The default value is 100.
    

        
    --with-suexec-logfile
    
        
    This defines the filename of the suexec logfile.
          By default the logfile is named suexec_log and located in
          --logfiledir.
    

        
    --with-suexec-safepath
    
        
    Define the value of the environment variable PATH to
          be set for processes started by suexec. Default
          value is /usr/local/bin:/usr/bin:/bin.
    

        
    --with-suexec-userdir
    
        
    This defines the subdirectory under the user's directory that
          contains all executables for which suexec access
          is allowed. This setting is necessary when you want to use
          suexec together with user-specific directories (as
          provided by mod_userdir). The default is
          public_html.
    

        
    --with-suexec-uidmin
    
        
    Define this as the lowest UID allowed to be a target user for
          suexec. The default value is 100.
    

        
    --with-suexec-umask
    
        
    Set umask for processes started by
          suexec. It defaults to your system settings.
    
      
    
    
  

    top
    

    

    Environment variables
    
  
    There are some useful environment variables to override the choices made by
    configure or to help it to find libraries and programs with
    nonstandard names or locations.
    

  
  
    
    
    CC
    
    
    Define the C compiler command to be used for compilation.
    

    
    CFLAGS
    
    
    Set C compiler flags you want to use for compilation.
    

    
    CPP
    
    
    Define the C preprocessor command to be used.
    

    
    CPPFLAGS
    
    
    Set C/C++ preprocessor flags, e.g. -Iincludedir
      if you have headers in a nonstandard directory includedir.
    

    
    LDFLAGS
    
    
    Set linker flags, e.g. -Llibdir if you have
      libraries in a nonstandard directory libdir.

suexec - Switch user before executing external programs - Apache HTTP Server Version 2.4

    suexec - Switch user before executing external programs
    

    

    Available Languages:  en  |

    suexec is used by the Apache HTTP Server to switch
     to another user before executing CGI programs. In order to achieve this,
     it must run as root. Since the HTTP daemon normally doesn't
     run as root, the suexec executable needs the
     setuid bit set and must be owned by root. It should never be
     writable for any other person than root.
    

     
    For further information about the concepts and the security model
     of suexec please refer to the suexec documentation (http://httpd.apache.org/docs/2.4/suexec.html).

    Options
    


    

    -V
    


    If you are root, this option displays the compile options of
suexec. For security reasons all configuration options are
changeable only at compile time.

 tr 
    

    

    
    dbmmanage is used to create and update the DBM format files
    used to store usernames and password for basic authentication of HTTP users
    via mod_authn_dbm.
    Resources available from the Apache HTTP server can be restricted to just
    the users listed in the files created by dbmmanage. This
    program can only be used when the usernames are stored in a DBM file. To
    use a flat-file database see htpasswd.
    

    
    Another tool to maintain a DBM password database is
    htdbm.
    

    
    This manual page only lists the command line arguments. For details of
    the directives necessary to configure user authentication in
    httpd see the httpd manual, which is part of
    the Apache distribution or can be found at http://httpd.apache.org/.

    dbmmanage filename import
    

    top
    

    

    Options
    
    
    
    
    filename
    
    
    The filename of the DBM format file. Usually without the extension
    .db, .pag, or .dir.
    

    
    username
    
    
    The user for which the operations are performed. The username
    may not contain a colon (:).
    

    
    encpasswd
    
    
    This is the already encrypted password to use for the
    update and add commands. You may use a hyphen
    (-) if you want to get prompted for the password, but fill
    in the fields afterwards. Additionally when using the update
    command, a period (.) keeps the original password
    untouched.
    

    
    group
    
    
    A group, which the user is member of. A groupname may not contain a
    colon (:). You may use a hyphen (-) if you don't
    want to assign the user to a group, but fill in the comment field.
    Additionally when using the update command, a period
    (.) keeps the original groups untouched.
    

    
    comment
    
    
    This is the place for your opaque comments about the user, like
    realname, mailaddress or such things. The server will ignore this
    field.
    
    
    

    
    Encodings
    
      
    
      
    -d
    
      
    crypt encryption (default, except on Win32, Netware)
    

      
    -m
    
      
    MD5 encryption (default on Win32, Netware)
    

      
    -s
    
      
    SHA1 encryption
    

      
    -p
    
      
    plaintext (not recommended)
    
      
    
    

    
    Commands
    
      
    
      
    add
    
      
    Adds an entry for username to filename using the
      encrypted password encpasswd.

      
    dbmmanage passwords.dat add rbowen foKntnEF3KSXA
    
      
    

      
    adduser
    
      
    Asks for a password and then adds an entry for username to
      filename.

      
    dbmmanage passwords.dat adduser krietz
    
      
    

      
    check
    
      
    Asks for a password and then checks if username is in
      filename and if it's password matches the specified one.

      
    dbmmanage passwords.dat check rbowen
    
      
    

      
    delete
    
      
    Deletes the username entry from filename.

      
    dbmmanage passwords.dat delete rbowen
    
      
    

      
    import
    
      
    Reads username:password entries
      (one per line) from STDIN and adds them to
      filename. The passwords already have to be crypted.
    

      
    update
    
      
    Same as the adduser command, except that it makes
      sure username already exists in filename.

      
    dbmmanage passwords.dat update rbowen
    
      
    

      
    view
    
      
    Just displays the contents of the DBM file. If you specify a
      username, it displays the particular record only.

      
    dbmmanage passwords.dat view

    Bugs
    
    
    One should be aware that there are a number of different DBM file formats
    in existence, and with all likelihood, libraries for more than one format
    may exist on your system. The three primary examples are SDBM, NDBM, the GNU
    project's GDBM, and Berkeley DB 2. Unfortunately, all these libraries use
    different file formats, and you must make sure that the file format used
    by filename is the same format that dbmmanage
    expects to see. dbmmanage currently has no way of determining
    what type of DBM file it is looking at. If used against the wrong format,
    will simply return nothing, or may create a different DBM file with a
    different name, or at worst, it may corrupt the DBM file if you were
    attempting to write to it.
    

    
    dbmmanage has a list of DBM format preferences, defined by
    the @AnyDBM::ISA array near the beginning of the program. Since
    we prefer the Berkeley DB 2 file format, the order in which
    dbmmanage will look for system libraries is Berkeley DB 2,
    then NDBM, then GDBM and then SDBM. The first library found will be the
    library dbmmanage will attempt to use for all DBM file
    transactions. This ordering is slightly  different than the standard
    @AnyDBM::ISA ordering in Perl, as well as the ordering used by
    the simple dbmopen() call in Perl, so if you use any other
    utilities to manage your DBM files, they must also follow this preference
    ordering. Similar care must be taken if using programs in other languages,
    like C, to access these files.
    

    
    One can usually use the file program supplied with most
    Unix systems to see what format a DBM file is in.

    httpd, Apache Hiper Metin Aktarım
      Protokolü (HTTP) sunucusu programıdır. Tek başına çalışan bir artalan
      süreci olarak tasarlanmıştır. Bu tarz kullanıldığında istekleri işleme
      sokmak için çocuk süreçlerden ve evrelerden oluşan bir havuz
      oluşturur.
    

     
    Genelde, httpd'nin doğrudan çağrılmaması
      gerekir. Unix ve benzerlerinde apachectl
      aracılığıyla, Windows NT, 2000
      ve XP'de bir hizmet olarak,  Windows 9x ve ME'de ise bir
      konsol uygulaması olarak çalıştırılır.

     [ -w ]
    

    top
    

    

    Seçenekler
    

  
    
    
    -d sunucu-kök-dizini
    
      
    sunucu-kök-dizini'ni ServerRoot yönergesine ilk değer olarak atar. Yapılandırma
      dosyasındaki bir ServerRoot
      yönergesiyle bu atama geçersiz kılınabilir. Bu seçenek belirtilmediği
      takdirde /usr/local/apache2 dizini öntanımlıdır.
    

    
    -f yapılandırma-dosyası
    
      
    Başlatma sırasında yapılandırma-dosyası'ndaki yönergeler
      kullanılır. Eğer yapılandırma-dosyası bir / ile başlamıyorsa
      dosyanın ServerRoot yönergesinin
      değerine göreli olduğu varsayılır. Seçenek belirtilmediği takdirde
      conf/httpd.conf öntanımlı değerdir.
    

    
    -k start | restart | graceful | stop |
      graceful-stop
    
    
    httpd'yi başlatmak, durdurmak ve yeniden
      başlatmak için sinyal gönderir. Daha ayrıntılı bilgi edinmek için Apache httpd'nin Durdurulması belgesine
      bakınız.
    

    
    -C yönerge
    
    
    Yapılandırma yönerge'sini yapılandırma dosyalarını okumadan
      önce işleme sokar.
    

    
    -c yönerge
    
    
    Yapılandırma yönerge'sini yapılandırma dosyalarını
      okuduktan sonra işleme sokar.
    

    
    -D parametre
    
    
    Sunucu başlatılırken veya yeniden başlatılırken komutları şarta bağlı
      olarak işleme sokmak veya atlamak için yapılandırma dosyalarında
      kullanılan <IfDefine>
      bölümlerinde kullanılmak üzere bir yapılandırma parametre'si
      tanımlar. Ayrıca, -DNO_DETACH (ana sürecin çatallanmasını
      engellemek için), -DFOREGROUND (ana sürecin
      setsid() ve benzerlerinden çağrılmasını engellemek için)
      gibi daha az bilinen bazı başlatma parametrelerini atamakta da
      kullanılabilir.
    

    
    -e seviye
    
    
    Hata günlüğü seviyesi olarak LogLevel yönergesine sunucu başlatılırken seviye
      değerini atar. Bu seçenek, başlatma sırasındaki sorunları saptamak
      amacıyla hata iletilerinin ayrıntı seviyesini geçici olarak arttırmak
      için kullanılır.
    

    
    -E dosya
    
    
    Sunucunun başlatılması sırasında hata iletilerinin belirtilen
      dosya'ya gönderilmesini sağlar.
    

    
    -h
    
    
    Mevcut komut satırı seçeneklerinin kısa bir özetini çıktılar.
    

    
    -l
    
    
    Sunucunun içinde derlenmiş modüllerin listesini çıktılar. Bu liste
      LoadModule yönergesi kullanılarak
      devingen olarak yüklenen modülleri içermez.
    

    
    -L
    
    
    Durağan modüllerce sağlanmış yönergeleri olası değerleriyle geçerli
      konumlarına yerleştirerek listeler. Paylaşımlı modüllerce sağlanan
      yönergeleri listelemez.
    

    
    -M
    
    
    Yüklü durağan ve paylaşımlı modülleri listeler.
    

    
    -S
    
    
    Yapılandırma dosyasından çözümlenmiş haliyle ayarları gösterir (şu an
      sadece sanal konak ayarları gösterilmektedir).
    

    
    -T (2.3.8 ve sonrasında
    kullanılabilmektedir)
    
    
    Başlatma ve yeniden başlatma sırasında belge kökü sınanmadan
      geçilir.
    

    
    -t
    
    
    Yapılandırma dosyasını sözdizimi hatalarına karşı denetler. Program
      sözdizimini denetledikten sonra sözdizimi geçerliyse 0 ile, değilse
      sıfırdan farklı bir değerle çıkar.
      -DDUMP_VHOSTS seçeneği ile birlikte
      kullanılmışsa ek olarak sanal konak ayrıntıları da basılır.
      -DDUMP_MODULES seçeneği ile ise ek olarak
      tüm modüller listelenir.
    

    
    -v
    
    
    httpd sürümünü basar ve çıkar.
    

    
    -V
    
    
    Sürümü ve httpd kurulum parametrelerini
      basar ve çıkar.
    

    
    -X
    
    
    httpd hata ayıklama kipinde çalışır. Tek
      çocuk süreç başlatılır ve sunucu konsolu terketmez.
    
  
    

  
    Aşağıdaki seçenekler sadece Windows
    platformunda geçerlidir:
    

  
    
    
    -k install | config | uninstall
    
    
    Parametreler bakımından sırasıyla: Apache httpd bir Windows NT hizmeti
      haline getirilir; başlatma seçenekleri Apache httpd hizmeti için
      değiştirilir; ve Apache httpd hizmeti sistemden kaldırılır.
    

    
    -n isim
    
    
    Sinyal gönderilecek Apache httpd hizmetinin ismi.
    

    
    -w
    
    
    Hata durumunda konsol penceresi açık tutularak hata iletilerinin
      okunması sağlanır.

    Seçenekler
    
    
    
    
    -b
    
    
    Betik kipi; parola için istek yapmak yerine parola komut satırından
    verilir. Parola komut satırında görünür olacağından çok
    dikkatli kullanmak gerekir. Betik kullanımı için
    -i seçeneğine bakınız.
    

    
    -i
    
    
    Parolayı doğrulamaksızın standart girdiden okur (betik kullanımı
    için).
    

    
    -c
    
    
    parola-dosyası oluşturur. Dosya mevcutsa,
    dosya silinip yeniden yazılır. Bu seçenek
    -n seçeneği ile birlikte kullanılamaz.
    

    
    -n
    
    
    Sonuçları veritabanında güncellemek yerine standart çıktıya gönderir.
    parola-dosyası belirtilmediğinden, bu seçenek
    komut satırı sözdizimini değiştirir. Bu seçenek
    -c seçeneği ile birlikte kullanılamaz.
    

    
    -m
    
    
    Parolalar için MD5 şifrelemesi kullanılır. Windows ve Netware
    için bu öntanımlıdır.
    

    
    -B
    
    
    Parolalar için bcrypt şifrelemesi kullanılır. Şu an için çok güvenli
    kabul edilmektedir.
    

    
    -C  bedel
    
    
    Bu seçenek sadece -B (bcrypt şifrelemesi)
    seçeneği ile birlikte kullanılabilir. Bcrypt algoritmasına hesaplama
    süresini belirtir (daha yüksek değerler daha güvenlidir, öntanımlı 5,
    geçerli değerler: 4 - 31).
    

    
    -d
    
    
    Parolaları şifrelemek için crypt() kullanılır. Windows,
    ve Netware dışında öntanımlıdır.
    htdbm tarafından tüm platformlarda
    destekleniyor olsa da Windows ve Netware üzerinde
    httpd sunucusu tarafından desteklenmez. Bu algoritma
    günümüz standartlarında güvenilmez kabul
    edilmektedir.
    

    
    -s
    
    
    Parolalar için SHA şifrelemesi kullanılır. LDAP Dizin değişim
    biçemini (ldif) kullanarak Netscape sunucularına/sunucularından göçü
    kolaylaştırır. Bu algoritma günümüz standartlarında
    güvenilmez kabul edilmektedir.
    

    
    -p
    
    
    Düz metin parolalar kullanılır. htdbm
    tarafından tüm platformlarda destekleniyor olsa da Windows, Netware ve
    TPF üzerinde httpd sunucusu tarafından sadece düz
    metin parolalar kabul edilir.
    

    
    -l
    
    
    Veritabanındaki kullanıcıları açıklamalarıyla birlikte standart
    çıktıya gönderir.
    

    
    -v
    
    
    Kullanıcı adını ve parolasını doğrular. Program belirtilen parolanın
    geçerli olup olmadığını belirten bir ileti basar. Eğer parola geçersizse
    program hata kodu 3 ile çıkar.
    

    
    -x
    
    
    Kullanıcıyı siler. Kullanıcı belirtilen DBM dosyasında mevcutsa
    silinir.
    

    
    -t
    
    
    Son değiştirgenin bir açıklama olarak yorumlanmasını sağlar. Bu
    seçenek kullanıldığında komut satırının sonuna fazladan bir dizge
    eklenebilir. Bu dizge, veritabanında belirtilen kullanıcının "Comment"
    alanında saklanır.
    

    
    parola-dosyası
    
    
    DBM dosyasının ismi. Genellikle, .db, .pag
    veya .dir eklentisi olmaksızın belirtilir.
    -c seçeneği ile birlikte verilmişse ve DBM
    dosyası mevcut değilse dosya oluşturulur, mevcutsa dosya güncellenir.
    

    
    kullanıcı
    
    
    parola-dosyası'nda oluşturulacak veya
    güncellenecek kullanıcı ismi. kullanıcı bu
    dosyada mevcut değilse yeni bir girdi eklenir. Girdi mevcutsa parolası
    değiştirilir.
    

    
    parola
    
    
    Şifrelenip DBM dosyasında saklanacak düz metin parola. Sadece
    -b seçeneği ile kullanılır.
    

    
    -T VTtürü
    
    
    DBM dosyasının türü; SDBM, GDBM, DB, veya "default" olabilir.
    
    
    

    top
    

    

    Hatalar
    
    
    Birden fazla DBM dosya biçemi vardır ve büyük bir olasılıkla da
    sisteminizde bu birden fazla biçemle ilgili kütüphaneler vardır. SDBM,
    NDBM, GNU'nun GDBM projesi ve Berkeley/Sleepycat DB 2/3/4 bunların
    başlıcalarıdır. Ne yazık ki, bu kütüphanelerin her birinin dosya
    biçimleri farklıdır. Bu bakımdan, dosyaismi
    dosyasında kullanılan dosya biçeminin htdbm
    tarafından kullanılanla aynı biçemde olduğundan emin olmalısınız.
    htdbm hangi tür DBM dosyasına baktığını
    saptayacak yeterliliğe sahip değildir. Yanlış biçemli bir dosya
    belirtirseniz hiçbir şey dönmeyebileceği gibi, başka isimde bir DBM
    dosyasının oluşturulması veya daha da kötüsü üzerine yazmaya
    çalışıyorsanız DBM dosyasının bozulması bile olasıdır.
    

    
    Unix sistemlerinde, kullanılan DBM dosyasının biçemini öğrenmek için
    file programı kullanılabilir.
    

    top
    

    

    Çıkış Durumu
    
    
    htdbm, kullanıcı ismi ve parolasını DBM
    dosyasına başarıyla eklemiş veya güncellemişse 0, dosyalara
    erişirken bir sorun çıkmışsa 1, komut satırında bir
    sözdizimi hatası varsa 2, parola etkileşimli alınmış fakat
    girdi ile eşleşme sağlanamamışsa 3, işlem kesintiye
    uğramışsa 4, bir değer çok uzunsa 5 (kullanıcı,
    parola, dosya ismi veya açıklama), kullanıcı ismi kuraldışı karakter
    içeriyorsa (Kısıtlamalar bölümüne bakınız)
    6 ve dosya geçerli bir DBM parola dosyası değilse
    7 değeriyle döner.

    Örnekler
    
    
    
      htdbm /usr/local/etc/apache/.htdbm-users jsmith
    
    

    
    jsmith kullanıcısı için parolayı ekler veya değiştirir.
    Parolayı vermesi için kullanıcıya parola isteği yapılır. Windows üzerinde
    çalıştırılırsa parola Apache MD5 algoritması ile şifrelenir, aksi
    takdirde sistemin crypt() yordamı kullanılır. Dosya mevcut
    değilse htdbm beklenen hiçbir işlemi
    yapmadan bir hata vererek çıkar.
    

    
    
      htdbm -c /home/doe/public_html/.htdbm jane
    
    

    
    Yeni bir dosya oluşturur ve kullanıcı jane için kaydı bir
    girdi olarak bu dosyaya yazar. Dosya mevcutsa fakat okunamıyor veya
    yazılamıyorsa dosyada bir değişiklik yapılmaz ve
    htdbm bir ileti gösterip bir hata durumu
    ile çıkar.
    

    
    
      htdbm -mb /usr/web/.htdbm-all jones Pwd4Steve
    
    

    
    Komut satırından verilen parolayı (Pwd4Steve) MD5
    algoritmasıyla şifreler ve bunu belirtilen dosyada saklar.
    

    top
    

    

    Güvenlik Değerlendirmeleri
    
    
    htdbm tarafından yönetilen parola
    dosyalarına sunucunun URI uzayından erişilememelidir; yani dosya bir
    tarayıcı ile okunabilecek bir yerde bulunmamalıdır.
    

    
    Komut satırında parolanın şifrelenmemiş olarak görünmesi sebebiyle
    -b seçeneğinin kullanımından kaçınılmasını
    öneriyoruz.
    

    
    crypt() algoritması kullanılırken, parolayı
    şekillendirmek için parolanın ilk 8 baytının kullanılacağına dikkat
    ediniz. Eğer parola 8 bayttan uzunsa kalanlar bir uyarı verilmeksizin
    iptal edilir.
    

    
    SHA şifreleme biçeminde tuz kullanılmaz; yani, bir parolanın
    sadece bir şifreli gösterimi olabilir. crypt() ve
    MD5 biçemleri parolanın önüne rasgele üretilmiş bir tuz dizgesi
    eklediklerinden sözlük saldırılarına karşı daha dayanıklıdır.
    

    
    SHA ve crypt() biçimleri günümüz standartlarında
    güvenilmez kabul edilmektedir.
    

    top
    

    

    Kısıtlamalar
    
    
    Windows platformunda, htdbm
    ile şifrelenen parolalar 255 karakterden daha uzun olamaz.
    255 karakterden sonrası kırpılır.
    

    
    htdbm tarafından kullanılan MD5
    algoritması Apache yazılımına özeldir; bu algoritma ile şifrelenen
    parolalar başka HTTP sunucularında kullanılamayabilir.
    

    
    Kullanıcı isimleri 255 bayttan uzun olamaz ve iki nokta
    imi (:) içeremez.

    htcacheclean is used to keep the size of
    mod_cache_disk's storage within a given size limit, or
    limit on inodes in use. This tool can run either manually or in daemon mode.
    When running in daemon mode, it sleeps in the background and checks the cache
    directory at regular intervals for cached content to be removed. You can stop
    the daemon cleanly by sending it a TERM or INT signal. When run manually, a
    once off check of the cache directory is made for cached content to be
    removed. If one or more URLs are specified, each URL will be deleted from
    the cache, if present.

    Options
    
    
    
    
    -dinterval
    
    
    Daemonize and repeat cache cleaning every interval minutes.
    This option is mutually exclusive with the -D, -v
    and -r options. To shutdown the daemon cleanly, just send it
    a SIGTERM or SIGINT.
    

    
    -D
    
    
    Do a dry run and don't delete anything. This option is mutually
        exclusive with the -d option. When doing a dry run and
        deleting directories with -t, the inodes reported deleted
        in the stats cannot take into account the directories deleted, and will
        be marked as an estimate.
    

    
    -v
    
    
    Be verbose and print statistics. This option is mutually exclusive
    with the -d option.
    

    
    -r
    
    
    Clean thoroughly. This assumes that the Apache web server is
    not running (otherwise you may get garbage in the cache). This option
    is mutually exclusive with the -d option and implies
    the -t option.
    

    
    -n
    
    
    Be nice. This causes slower processing in favour of other
    processes. htcacheclean will sleep from time to time
    so that (a) the disk IO will be delayed and (b) the kernel can schedule
    other processes in the meantime.
    

    
    -t
    
    
    Delete all empty directories. By default only cache files are
    removed, however with some configurations the large number of
    directories created may require attention. If your configuration
    requires a very large number of directories, to the point that
    inode or file allocation table exhaustion may become an issue, use
    of this option is advised.
    

    
    -ppath
    
    
    Specify path as the root directory of the disk cache. This
    should be the same value as specified with the CacheRoot directive.
    

    
    -Ppidfile
    
    
    Specify pidfile as the name of the file to write the
    process ID to when daemonized.
    

    
    -Rround
    
    
    Specify round as the amount to round sizes up to, to
    compensate for disk block sizes. Set to the block size of the cache
    partition.
    

    
    -llimit
    
    
    Specify limit as the total disk cache size limit. The value
    is expressed in bytes by default (or attaching B to the
    number). Attach K for Kbytes, M for
    MBytes or G for Gbytes.
    

    
    -Llimit
    
    
    Specify limit as the total disk cache inode limit.
    K, M or G suffix can also be
    used.
    

    
    -i
    
    
    Be intelligent and run only when there was a modification of the disk
    cache. This option is only possible together with the -d
    option.
    

    
    -a
    
    
    List the URLs currently stored in the cache. Variants of the same URL
    will be listed once for each variant.
    

    
    -A
    
    
    List the URLs currently stored in the cache, along with their
    attributes in the following order: url, header size, body size, status,
    entity version, date, expiry, request time, response time, body present,
    head request.
    
    
    


    top
    

    

    Deleting a specific URL
    
    
    If htcacheclean is passed one or more URLs, each URL will
    be deleted from the cache. If multiple variants of an URL exists, all
    variants would be deleted.
    

    
    When a reverse proxied URL is to be deleted, the effective URL is
    constructed from the Host header, the
    port, the path and the
    query. Note the '?' in the URL must always be specified
    explicitly, whether a query string is present or not. For example, an
    attempt to delete the path / from the server
    localhost, the URL to delete would be
    http://localhost:80/?.
    


    top
    

    

    Listing URLs in the Cache
    
    
    By passing the -a or -A options to
    htcacheclean, the URLs within the cache will be listed
    as they are found, one URL per line. The -A option
    dumps the full cache entry after the URL, with fields in the
    following order:
    

    
    
        
    url
    The URL of the entry.
    
        
    header size
    The size of the header in bytes.
    
        
    body size
    The size of the body in bytes.
    
        
    status
    Status of the cached response.
    
        
    entity version
    The number of times this entry has been
        revalidated without being deleted.
    
        
    date
    Date of the response.
    
        
    expiry
    Expiry date of the response.
    
        
    request time
    Time of the start of the request.
    
        
    response time
    Time of the end of the request.
    
        
    body present
    If 0, no body is stored with this request,
        1 otherwise.
    
        
    head request
    If 1, the entry contains a cached HEAD
        request with no body, 0 otherwise.
    
    
    


    top
    

    

    Exit Status
    
    
    htcacheclean returns a zero status ("true") if all
    operations were successful, 1 otherwise. If an URL is
    specified, and the URL was cached and successfully removed,
    0 is returned, 2 otherwise. If an error
    occurred during URL removal, 1 is returned.

    htdbm is used to manipulate the DBM format files used to
    store usernames and password for basic authentication of HTTP users via
    mod_authn_dbm.  See the dbmmanage
    documentation for more information about these DBM files.

    Options
    
    
    
    
    -b
    
    
    Use batch mode; i.e., get the password from the command line
    rather than prompting for it. This option should be used with extreme care,
    since the password is clearly visible on the command
    line. For script use see the -i option.
    

    
    -i
    
    
    Read the password from stdin without verification (for script usage).
    

    
    -c
    
    
    Create the passwdfile. If passwdfile already
    exists, it is rewritten and truncated. This option cannot be combined with
    the -n option.
    

    
    -n
    
    
    Display the results on standard output rather than updating a
    database.  This option changes the syntax of the command line, since the
    passwdfile argument (usually the first one) is omitted. It
    cannot be combined with the -c option.
    

    
    -m
    
    
    Use MD5 encryption for passwords. On Windows and Netware, this is
    the default.
    

    
    -B
    
    
    Use bcrypt encryption for passwords. This is currently considered to
    be very secure.
    

    
    -C
    
    
    This flag is only allowed in combination with -B (bcrypt
    encryption). It sets the computing time used for the bcrypt algorithm
    (higher is more secure but slower, default: 5, valid: 4 to 31).
    

    
    -d
    
    
    Use crypt() encryption for passwords. The default on all
    platforms but Windows and Netware. Though possibly supported by
    htdbm on all platforms, it is not supported by the
    httpd server on Windows and Netware.
    This algorithm is insecure by today's standards.
    

    
    -s
    
    
    Use SHA encryption for passwords. Facilitates migration from/to Netscape
    servers using the LDAP Directory Interchange Format (ldif).
    This algorithm is insecure by today's standards.
    

    
    -p
    
    
    Use plaintext passwords. Though htdbm will support
    creation on all platforms, the httpd daemon will
    only accept plain text passwords on Windows and Netware.
    

    
    -l
    
    
    Print each of the usernames and comments from the database on
    stdout.
    

    
    -v
    
    
    Verify the username and password.  The program will print a message
    indicating whether the supplied password is valid.  If the password is
    invalid, the program exits with error code 3.
    

    
    -x
    
    
    Delete user. If the username exists in the specified DBM file, it
    will be deleted.
    

    
    -t
    
    
    Interpret the final parameter as a comment.  When this option is
    specified, an additional string can be appended to the command line; this
    string will be stored in the "Comment" field of the database, associated
    with the specified username.
    

    
    filename
    
    
    The filename of the DBM format file. Usually without the extension
    .db, .pag, or .dir.  If
    -c is given, the DBM file is created if it does not already
    exist, or updated if it does exist.
    

    
    username
    
    
    The username to create or update in passwdfile. If
    username does not exist in this file, an entry is added. If it
    does exist, the password is changed.
    

    
    password
    
    
    The plaintext password to be encrypted and stored in the DBM file.
    Used only with the -b flag.
    

    
    -TDBTYPE
    
    
    Type of DBM file (SDBM, GDBM, DB, or "default").
    
    
    

    top
    

    

    Bugs
    
    
    One should be aware that there are a number of different DBM file
    formats in existence, and with all likelihood, libraries for more than
    one format may exist on your system. The three primary examples are
    SDBM, NDBM, GNU GDBM, and Berkeley/Sleepycat DB 2/3/4. Unfortunately,
    all these libraries use different file formats, and you must make sure
    that the file format used by filename is the same format that
    htdbm expects to see. htdbm currently has
    no way of determining what type of DBM file it is looking at. If used
    against the wrong format, will simply return nothing, or may create a
    different DBM file with a different name, or at worst, it may corrupt
    the DBM file if you were attempting to write to it.
    

    
    One can usually use the file program supplied with most
    Unix systems to see what format a DBM file is in.
    

    top
    

    

    Exit Status
    
    
    htdbm returns a zero status ("true") if the username and
    password have been successfully added or updated in the DBM File.
    htdbm returns 1 if it encounters some problem
    accessing files, 2 if there was a syntax problem with the
    command line, 3 if the password was entered interactively and
    the verification entry didn't match, 4 if its operation was
    interrupted, 5 if a value is too long (username, filename,
    password, or final computed record), 6 if the username
    contains illegal characters (see the Restrictions
    section), and 7 if the file is not a valid DBM password
    file.
    

    top
    

    

    Examples
    
    
    
      htdbm /usr/local/etc/apache/.htdbm-users jsmith
    
    

    
    Adds or modifies the password for user jsmith. The user
    is prompted for the password. If executed on a Windows system, the password
    will be encrypted using the  modified Apache MD5 algorithm; otherwise, the
    system's crypt() routine will be used. If the file does not
    exist, htdbm will do nothing except return an error.
    

    
    
      htdbm -c /home/doe/public_html/.htdbm jane
    
    

    
    Creates a new file and stores a record in it for user jane.
    The user is prompted for the password. If the file exists and cannot be
    read, or cannot be written, it is not altered and htdbm
    will display a message and return an error status.
    

    
    
      htdbm -mb /usr/web/.htdbm-all jones Pwd4Steve
    
    

    
    Encrypts the password from the command line (Pwd4Steve)
    using the MD5 algorithm, and stores it in the specified file.
    

    top
    

    

    Security Considerations
    
    
    Web password files such as those managed by htdbm should
    not be within the Web server's URI space -- that is, they should
    not be fetchable with a browser.
    

    
    The use of the -b option is discouraged, since when it is
    used the unencrypted password appears on the command line.
    

    
    When using the crypt() algorithm, note that only the first
    8 characters of the password are used  to form the password. If the supplied
    password is longer, the extra characters will be silently discarded.
    

    
    The SHA encryption format does not use salting: for a given password,
    there is only one encrypted representation. The crypt() and
    MD5 formats permute the representation by prepending a random salt string,
    to make dictionary attacks against the passwords more difficult.
    

    
    The SHA and crypt() formats are insecure by today's
    standards.
    

    top
    

    

    Restrictions
    
    
    On the Windows platform, passwords encrypted with
    htdbm are limited to no more than 255
    characters in length. Longer passwords will be truncated to 255
    characters.
    

    
    The MD5 algorithm used by htdbm is specific to the Apache
    software; passwords encrypted using it will not be usable with other Web
    servers.
    

    
    Usernames are limited to 255 bytes and may not include the
    character :.

    logresolve est un programme agissant après
     traitement pour résoudre les adresses IP dans les journaux d'accès
     d'Apache. Pour minimiser la charge de votre serveur de noms,
     logresolve possède son propre cache interne sous forme d'une table
     de hashage. Cela implique que chaque numéro IP ne fera l'objet
     d'une requête DNS que la première fois où il est rencontré dans le
     fichier journal.
    

     
    Le programme reçoit le fichier journal sur son entrée standard.
     Les adresses IP doivent se trouver en tête de chaque ligne et
     doivent être séparées du reste de la ligne par un espace.

    Avec cette option, logresolve effectue certaines

adresse IP, logresolve effectue une recherche DNS sur ce
nom d'hôte et vérifie si une des adresses IP trouvées correspond à
l'adresse originale.

    apachectl - Apache HTTP Server Control Interface

    apachectl is a front end to the Apache HyperText
     Transfer Protocol (HTTP) server.  It is designed to help the
     administrator control the functioning of the Apache
     httpd daemon.
    

     
    The apachectl script can operate in two modes.
     First, it can act as a simple front-end to the httpd
     command that simply sets any necessary environment variables and
     then invokes httpd, passing through any command line
     arguments.  Second, apachectl can act as a SysV init
     script, taking simple one-word arguments like start,
     restart, and stop, and translating them
     into appropriate signals to httpd.
    

     
    If your Apache installation uses non-standard paths, you will
     need to edit the apachectl script to set the
     appropriate paths to the httpd binary.  You can also
     specify any necessary httpd command line arguments.
     See the comments in the script for details.
    

     
    The apachectl script returns a 0 exit value on
     success, and >0 if an error occurs.  For more details, view
     the comments in the script.
    

    


    top
    

    

    Synopsis
    


    When acting in pass-through mode, apachectl can take
all the arguments available for the httpd
binary.
    


    apachectl [ httpd-argument ]
    


    When acting in SysV init mode, apachectl takes simple,
one-word commands, defined below.
    


    apachectl command
    


    top
    

    

    Options
    


    Only the SysV init-style options are defined here.  Other arguments
are defined on the httpd manual page.
    


    


    start
    


    Start the Apache httpd daemon.  Gives an error if it
is already running.  This is equivalent to apachectl -k
start.
    


    stop
    


    Stops the Apache httpd daemon.  This is equivalent to
apachectl -k stop.
    


    restart
    


    Restarts the Apache httpd daemon.  If the daemon is
not running, it is started.  This command automatically checks the
configuration files as in configtest before initiating
the restart to make sure the daemon doesn't die.  This is equivalent
to apachectl -k restart.
    


    fullstatus
    


    Displays a full status report from mod_status.
For this to work, you need to have mod_status enabled
on your server and a text-based browser such as lynx
available on your system.  The URL used to access the status report
can be set by editing the STATUSURL variable in the
script.
    


    status
    


    Displays a brief status report.  Similar to the
fullstatus option, except that the list of requests
currently being served is omitted.
    


    graceful
    


    Gracefully restarts the Apache httpd daemon.  If the
daemon is not running, it is started.  This differs from a normal
restart in that currently open connections are not aborted.  A side
effect is that old log files will not be closed immediately.  This
means that if used in a log rotation script, a substantial delay may
be necessary to ensure that the old log files are closed before
processing them.  This command automatically checks the configuration
files as in configtest before initiating the
restart to make sure Apache doesn't die.  This is equivalent to
apachectl -k graceful.
    


    graceful-stop
    


    Gracefully stops the Apache httpd daemon.
This differs from a normal stop in that currently open connections are not
aborted.  A side effect is that old log files will not be closed immediately.
This is equivalent to apachectl -k graceful-stop.
    


    configtest
    


    Run a configuration file syntax test. It parses the configuration
files and either reports Syntax Ok
or detailed information about the particular syntax error.  This is
equivalent to apachectl -t.
    


    


    The following option was available in earlier versions but has been removed.
    


    


    startssl
    


    To start httpd with SSL support, you should edit
your configuration file to include the relevant directives and then
use the normal apachectl start.

    apachectl est un frontal pour le serveur HTTP
     Apache. Il a été conçu pour aider l'administrateur à contrôler le
     fonctionnement du démon Apache httpd.
    

     
    Le script apachectl possède deux modes de
     fonctionnement. Il peut fonctionner en tant que simple frontal
     de la commande httpd et ne fait alors que
     définir toute variable d'environnement nécessaire, puis invoque
     httpd en lui passant tout argument de ligne de
     commande souhaité. Il peut aussi fonctionner en tant que script
     d'initialisation SysV n'acceptant qu'un seul argument tel que
     start, restart et stop, et
     traduisant ce dernier en signaux appropriés pour le démon
     httpd.
    

     
    Si votre installation d'Apache utilise des chemins non
     standards, vous devrez éditer le script apachectl afin
     de définir les chemins appropriés pour le binaire
     httpd. Vous pouvez aussi spécifier tout argument
     de ligne de commande de httpd nécessaire. Voir
     les commentaires dans le script pour plus de détails.
    

     
    Le script apachectl renvoie une valeur égale à 0 en
     cas de succès, et une valeur supérieure à 0 en cas de problème.
     Voir les commentaires dans le script pour plus de détails.

    Résumé
    


    En mode frontal (pass-through), apachectl peut spécifier
tous les arguments qu'accepte le binaire httpd.
    


    apachectl [ argument-httpd ]
    


    En mode script d'initialisation SysV, apachectl
n'accepte qu'un seul des arguments définis ci-dessous.
    


    apachectl commande
    


    top
    

    

    Options
    


    Seules les options du style initialisation SysV sont décrites ici.
Les autres arguments sont décrits dans la page de manuel de
httpd.
    


    


    start
    


    Démarre le démon Apache httpd. Renvoie une erreur
s'il est déjà en cours d'exécution. Équivalent à apachectl -k
start.
    


    stop
    


    Arrête le démon Apache httpd. Équivalent à
apachectl -k stop.
    


    restart
    


    Redémarre le démon Apache httpd. Si le démon
n'est pas en cours d'exécution, il est démarré. Cette option vérifie
automatiquement les fichiers de configuration (de la même manière que
l'option configtest ) avant de lancer le redémarrage, afin
d'être sûr que le fonctionnement du démon ne sera pas compromis.
Equivalent à apachectl -k restart.
    


    fullstatus
    


    Affiche le rapport d'état complet du module
mod_status. Pour que ceci fonctionne,
mod_status doit être activé dans votre serveur et vous
devez disposer d'un navigateur en mode texte tel que lynx
sur votre système. L'URL utilisée pour accéder au rapport d'état peut
être modifiée en définissant la variable STATUSURL dans le
script.
    


    status
    


    Affiche un rapport d'état succinct. Similaire à l'option
fullstatus, excepté que la liste des requêtes en cours de
traitement est omise.
    


    graceful
    


    Redémarre le démon Apache httpd en douceur. Si le
démon n'est pas en cours d'exécution, il est démarré. À la différence
d'un redémarrage normal, les connexions en cours ne sont pas fermées.
Comme effet de bord, les anciens fichiers journaux ne seront pas fermés
immédiatement. Cela signifie que si l'on utilise un script de rotation
des journaux, un délai suffisant sera nécessaire afin d'être sûr que les
fichiers journaux seront bien fermés avant leur traitement par le script
de rotation. Cette option vérifie
automatiquement les fichiers de configuration (de la même manière que
l'option configtest ) avant de lancer le redémarrage, afin
d'être sûr que le fonctionnement du démon ne sera pas compromis.
Équivalent à apachectl -k graceful.
    


    graceful-stop
    


    Arrête le démon Apache httpd en douceur. À la
différence d'un arrêt normal, les connexions en cours ne sont pas
fermées. Comme effet de bord, les anciens fichiers journaux ne seront
pas fermés immédiatement. Équivalent à apachectl -k
graceful-stop.
    


    configtest
    


    Effectue une vérification de la syntaxe du fichier de configuration.
Avec cette option, le script parcourt le fichier de configuration et
renvoie soit Syntax Ok, soit des informations détaillées à
propos des éventuelles erreurs de syntaxe. Equivalent à apachectl
-t.
    


    


    Les options suivantes étaient disponibles dans les anciennes versions
et ont été supprimées.
    


    


    startssl
    


    Pour démarrer httpd avec le support SSL, vous
devez éditer votre fichier de configuration et y inclure les
directives appropriées, puis utiliser la commande de démarrage normale
apachectl start.

    Ce script perl permet d'extraire un journal pour chaque serveur
    virtuel à partir d'un journal d'accès global du serveur web. Pour
    que ce script fonctionne, le premier champ de chaque ligne du
    journal global doit contenir l'identité du serveur virtuel ; ce
    champ aura été ajouté à la directive LogFormat via la variable
    "%v".
    
    

    

    top
    

    

    Mode d'emploi
    

    
    Création d'un fichier journal comportant l'identité du serveur
    virtuel considéré :
    

    
    LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined_plus_vhost
CustomLog logs/access_log combined_plus_vhost
    


    
    Un fichier journal sera créé dans le répertoire à partir duquel
    vous exécutez le script pour chaque serveur virtuel qui apparaît
    dans le journal global. Ces fichiers journaux seront nommés à partir
    du nom du serveur virtuel considéré, avec l'extension
    .log.
    

    
    Le fichier journal global est lu depuis l'entrée standard stdin.
    Les entrées de ce journal sont alors ajoutées au journal du serveur
    virtuel correspondant.

    rotatelogs est un programme simple à utiliser en
     conjonction avec la fonctionnalité d'Apache de redirection dans un
     "pipe" des fichiers journaux. Il supporte une rotation basée sur un
     intervalle de temps ou une taille maximale du journal.

     [ décalage ]
    

    top
    

    

    Options
    


    


    -l
    

    Utilise le temps local plutôt que GMT comme base pour l'intervalle
de temps ou pour le formatage de strftime(3) avec une
rotation basée sur la taille.
    


    -L nom-lien
    

    Etablit un lien physique entre le fichier journal courant et le lien
spécifié. Cette option permet de consulter le journal de manière
continue malgré les rotations via une commande du style tail -F
nom-lien.
    

    Si le nom du lien spécifié n'est pas un chemin absolu, il est relatif au
répertoire de travail de rotatelogs qui correspond à la valeur de
la directive ServerRoot lorsque la commande
rotatelogs est exécutée par le serveur.

    

    


    -p programme
    

    Avec cette option, rotatelogs exécutera le programme
programme chaque fois qu'un nouveau fichier journal sera
ouvert. Le nom du fichier nouvellement ouvert est passé comme premier
argument au programme. Si l'exécution se produit après une rotation,
l'ancien nom du fichier journal est passé au programme comme second
argument. rotatelogs
n'attend pas la fin du programme pour continuer son
exécution, et cessera tout enregistrement de codes d'erreur lorsqu'il
aura terminé son processus. Le programme utilise les mêmes
canaux stdin, stdout, et stderr que rotatelogs, et hérite de son
environnement.
    


    -f
    

    Ouvre le fichier journal immédiatement, dès que
rotatelogs démarre, au lieu d'attendre la lecture de la
première entrée de journal (pour les sites peu chargés, il peut
s'écouler un temps substantiel entre le démarrage du serveur et le
traitement de la première requête, temps pendant lequel le fichier
journal associé n'"existe" pas, ce qui peut causer des problèmes à
certains utilitaires de journalisation automatiques).
    


    -D
    

    Crée les répertoires parents du répertoire dans lequel le fichier journal
sera placé s'ils n'existent pas déjà. Cela permet d'utiliser le formatage
strftime(3) non seulement dans le nom de fichier mais aussi dans le
chemin.
    


    -t
    

    Provoque une troncature du fichier journal au lieu d'une rotation.
Cela peut s'avérer utile lorsqu'un journal est élaboré en temps réel par
une commande telle que tail, l'archivage des données n'étant ici pas
nécessaire. Si aucun suffixe n'est ajouté au nom de fichier, les
chaînes de format contenant des caractères '%' sont cependant
respectées.

    


    -v
    

    Affiche une sortie verbeuse sur STDERR. La sortie contient le
résultat de l'interprétation de la configuration, ainsi que toutes les
opérations d'ouverture et de fermeture de fichiers.
    


    -c
    

    Crée un fichier journal pour chaque intervalle, même s'il est vide.
    


    -e
    

    Envoie les messages de journalisation vers stdout. Ceci s'avère
utile lorsque les journaux doivent être traités par un autre programme.
    


    -n nombre-de-fichiers
    

    Utilise une liste circulaire de fichiers sans repères de temps. Avec
-n 3, la série de fichiers conservés sera "logfile",
"logfile.1", "logfile.2" avec écrasement de "logfile".
Disponible à partir de la version 2.4.5 du serveur HTTP Apache.
    


    fichier-journal
    

    Le chemin et le nom de base du fichier journal. Si
fichier-journal contient des caractères '%', il est considéré
comme une chaîne de formatage pour strftime(3). Dans le cas
contraire, le suffixe .nnnnnnnnnn est automatiquement ajouté
et correspond au temps en secondes (sauf si l'option -t est spécifiée).
Les deux formats calculent le temps
de démarrage depuis le début de la période courante. Par exemple, si un
temps de rotation de 86400 est spécifié, les champs heure, minute et
seconde créés à partir du format strftime(3) auront tous
pour valeur 0, en référence au début de la période de 24 heures courante
(minuit).
    

    Si vous utilisez le formatage de noms de fichiers
strftime(3), assurez-vous que le format du fichier journal
possède une granularité suffisamment importante pour générer un nom de
fichier différent à chaque rotation des journaux. Si ce n'est pas le
cas, la rotation va écraser le fichier existant au lieu d'en générer un
nouveau. Par exemple, si fichier-journal était
/var/log/errorlog.%Y-%m-%d avec une rotation à 5
mégaoctets, et si la limite de 5 mégaoctets a été atteinte deux fois
dans la même journée, le même nom de fichier va être généré, et la
rotation va écraser le fichier existant.
    

    Si le nom du fichier journal n'est pas un chemin absolu, il est relatif au
répertoire de travail de rotatelogs qui correspond à la valeur de
la directive ServerRoot lorsque la commande
rotatelogs est exécutée par le serveur.  

    

    


    temps-rotation
    


    Le temps entre deux rotations des fichiers journaux en secondes. La
rotation intervient au début de cet intervalle. Par exemple, si le temps
de rotation est de 3600, la rotation des fichiers journaux s'effectuera
au début de chaque heure ; si le temps de rotation est de 86400, la
rotation des fichiers journaux s'effectuera chaque nuit à minuit. (Si
aucune donnée n'est enregistrée au cours d'un intervalle, aucun fichier
ne sera créé).
    


    taille-fichier(B|K|M|G)
    


    La taille maximale du fichier suivie par une des lettres
B (Octets), K (KOctets), M (MOctets)
ou G (GOctets).

    
Lorsque temps et taille sont spécifiés, la taille doit l'être après le
temps. La rotation interviendra alors aussitôt que l'une des deux limites
(temps ou taille) sera atteinte.

    

    


    décalage
    


    Le décalage en minutes par rapport au temps UTC. Par défaut, le
décalage est considéré comme nul et c'est le temps UTC qui est utilisé.
Par exemple, pour utiliser le temps local de la zone UTC -5 heures,
spécifiez une valeur de -300 pour cette option. Dans la
plupart des cas, il vaut mieux utiliser l'option -l que
spécifier un décalage.

    Exemples
    


    
     CustomLog "|bin/rotatelogs /var/log/fichier-journal 86400" common

    

     
    Cette directive crée les fichiers /var/log/fichier-journal.nnnn
     où nnnn correspond au temps système auquel la journalisation
     démarre effectivement (ce temps sera toujours un multiple du temps
     de rotation, si bien que vous pouvez synchroniser les scripts cron
     avec lui). A la fin de chaque temps de rotation (ici après 24
     heures), une nouvelle journalisation démarre.
    


    
     CustomLog "|bin/rotatelogs -l /var/log/fichier-journal.%Y.%m.%d 86400" common

    

     
    Cette directive crée les fichiers
     /var/log/fichier-journal.yyyy.mm.dd où yyyy correspond à l'année,
     mm au mois et dd au jour du mois. La journalisation basculera vers
     un nouveau fichier chaque jour à minuit, temps local.
    


    
     CustomLog "|bin/rotatelogs /var/log/fichier-journal 5M" common

    

     
    Cette directive va effectuer une rotation du fichier journal
     chaque fois que la taille de ce dernier atteindra 5 MOctets.
    


    
     ErrorLog "|bin/rotatelogs /var/log/journal-erreurs.%Y-%m-%d-%H_%M_%S 5M"

    
     
    Cette directive va effectuer une rotation du fichier journal des
     erreurs chaque fois que la taille de ce dernier atteindra 5
     MOctets, et le nom du fichier journal se présentera sous
     la forme journal-erreurs.YYYY-mm-dd-HH_MM_SS.
    


    
     CustomLog "|bin/rotatelogs -t /var/log/journal 86400" common

    

     
    Cet exemple crée le fichier /var/log/journal en le tronquant
     au démarrage, puis une fois par jour. Ce scénario implique qu'un
     processus séparé (tel que tail) traite le fichier en temps
     réel.

    ab est un utilitaire qui vous permet de tester les
    performances de votre serveur HTTP Apache. Il a été conçu pour vous
    donner une idée du degré de performances de votre installation
    d'Apache. Il vous permet en particulier de déterminer le nombre de
    réquêtes que votre installation d'Apache est capable de servir par
    seconde.

    -A nom-utilisateur:mot-de-passe
    
    
    Fournit le support d'une authentification de base vers le
    serveur. Les nom-utilisateur et mot-de-passe sont séparés par un
    seul caractère : et transmis sous forme codée base64.
    La chaîne est envoyée que le serveur en ait besoin ou non (qu'il ait
    renvoyé un code "401 authentication needed" ou non).
    

    
    -b taille-tampon
    
    
    Taille du tampon d'émission/réception TCP, en octets.
    

    
    -B adresse-locale
    
    
    Adresse à laquelle se rattacher lors des connexions sortantes.
    

    
    -c simultanéité
    
    
    Nombre de requêtes à effectuer simultanément. Par défaut, une
    seule requête est effectuée à la fois.
    

    
    -C nom-cookie=valeur
    
    
    Ajoute une ligne Cookie: à la requête. L'argument
    se présente en général sous la forme d'une
    paire nom=valeur. Ce champ peut
    être répété.
    

    
    -d
    
    
    
    N'affiche pas le "pourcentage servi dans la table XX [ms]".
    (support de l'héritage).
    

    
    -e fichier-csv
    
    
    Enregistre des valeurs séparées par des virgules (CSV) dans un
    fichier, indiquant pour chaque pourcentage (de 1% à 100 %), le temps
    (en millisecondes) mis pour servir ce pourcentage de requêtes. Ce
    fichier est en général plus utile qu'un fichier 'gnuplot', car les
    résultats sont déjà sous forme binaire.
    

    
    -E fichier du certificat client
    
    
    Utilise le certificat client au format PEM qu'il contient pour
    s'authentifier auprès du serveur lors d'une connexion à un site web sous
    SSL. Ce fichier doit contenir le certificat client suivi des certificats
    intermédiaires et de la clé privé. Disponible à partir de la version 2.4.36
    du serveur HTTP Apache.
    

    
    -f protocole
    
    
    Spécifie le protocole SSL/TLS (SSL2, SSL3, TLS1, TLS1.1, TLS1.2, or ALL).
    TLS1.1 et TLS1.2 sont supportés à partir de la version 2.4.4 du
    serveur HTTP Apache.
    

    
    -g fichier-gnuplot
    
    
    Enregistre toutes les valeurs mesurées dans un fichier 'gnuplot'
    ou TSV (valeurs séparées par des tabulations). Ce fichier peut être
    facilement importé dans des programmes comme Gnuplot, IDL,
    Mathematica, Igor ou même Excel. La première ligne du fichier
    contient les noms des valeurs.
    

    
    -h
    
    
    Affiche une aide à propos de l'utilisation du programme.
    

    
    -H en-tête-personnalisé
    
    
    Ajoute des en-têtes supplémentaires à la requête. L'argument se
    présente sous la forme d'une ligne d'en-tête valide, autrement dit
    une paire champ/valeur séparés par un caractère ':' (par exemple
    "Accept-Encoding: zip/zop;8bit").
    

    
    -i
    
    
    Effectue des requêtes HEAD plutôt que
    GET.
    

    
    -k
    
    
    Active la fonctionnalité des connexions HTTP persistantes
    (KeepAlive), c'est à dire effectue plusieurs requêtes au cours d'une
    seule session HTTP. Cette fonctionnalité est désactivée par
    défaut.
    

    
    -l
    
    
    Ne signale pas les erreurs si la taille de la réponse n'est pas
    constante. Cette option peut s'avérer utile pour les pages
    dynamiques. Disponible à partir de la version 2.4.7 du serveur HTTP
    Apache.
    
    

    
    -m HTTP-method
    
    
    Méthode HTTP personnalisée à utiliser pour les requêtes.
    Disponible à partir de la version 2.4.10 du serveur HTTP
    Apache.
    

    
    -n requêtes
    
    
    Nombre de requêtes à effectuer au cours du test de performances.
    Par défaut, une seule requête est effectuée, ce qui ne permet pas
    d'obtenir des résultats représentatifs.
    

    
    -p fichier-POST
    
    
    Fichier contenant les données pour les requêtes POST.
    Assurez-vous de spécifier aussi le paramètre -T.
    

    
    -P nom-utilisateur-mandataire:mot-de-passe
    
    
    Fournit les informations d'authentification basique pour un
    mandataire en-route. Les nom d'utilisateur et mot de passe sont
    séparés par un simple caractère : et envoyés sur le
    réseau codés en base64. La chaîne est envoyée, que le mandataire en
    ait besoin ou non (qu'il ait renvoyé un code "407 proxy
    authentication needed" ou non).
    

    
    -q
    
    
    Lorsque plus de 150 requêtes sont traitées, ab
    affiche la progression du traitement sur stderr tous
    les 10% du nombre total ou toutes les 100 requêtes. Le drapeau
    -q permet de supprimer ces messages.
    

    
    -r
    
    
    Ne s'arrête pas en cas d'erreur de réception du socket.
    

    
    -s timeout
    
    
    Temps maximum d'attente en secondes du socket avant de considérer
    le délai comme dépassé. La valeur par défaut est de 30 secondes.
    Disponible à partir de la version 2.4.4 du serveur HTTP
    Apache.
    

    
    -S
    
    
    N'affiche ni les valeurs de déviation standards et médianes, ni
    les messages d'erreur et d'avertissement lorsque les valeurs
    médianes et moyennes sont égales à une ou deux fois la valeur de
    déviation standard. Par défaut les valeurs mini/moyenne/maxi sont
    affichées (support de l'héritage).
    
    

    
    -t limite-durée
    
    
    Durée maximale en secondes du test de performances. Ceci
    implique un -n 50000 en interne. Utilisez cette option
    si vous souhaitez tester les performances du serveur pendant une
    durée fixée à l'avance. Par défaut, il n'y a pas de limite de
    durée.
    

    
    -T type-contenu
    
    
    Valeur de l'en-tête Content-type à utiliser pour les données
    POST/PUT, par exemple
    application/x-www-form-urlencoded.
    La valeur par défaut est text/plain.
    

    
    -u fichier PUT
    
    
    Fichier contenant des données PUT.  Ne pas oublier de spécifier
    aussi -T.
    

    
    -v verbosité
    
    
    Définit le niveau de verbosité - les niveaux 4 et
    supérieurs permettent d'afficher des informations à propos des
    en-têtes, les niveaux 3 et supérieurs les codes de
    réponse (404, 200, etc...), et les niveaux 2 et
    supérieurs les messages d'avertissement et d'information.
    

    
    -V
    
    
    Affiche le numéro de version et s'arrête.
    

    
    -w
    
    
    Affiche les résultats dans des tables HTML. La table par défaut
    comporte deux colonnes sur fond blanc.
    

    
    -x <table>-attributs
    
    
    La chaîne à utiliser comme attributs pour
    <table>. Les attributs sont insérés
    <table ici >.
    

    
    -X mandataire[:port]
    
    
    Utilise un serveur mandataire pour les requêtes.
    

    
    -y <tr>-attributs
    
    
    La chaîne à utiliser comme attributs pour
    <tr>.

    Vous touverez dans ce qui suit la liste des valeurs retournées
    par ab :
    
    

    
    
        
    Server Software
    
        
    La valeur, si elle existe, de l'en-tête HTTP
	server renvoyée dans la première réponse réussie.
	Elle comporte tous les caractères de l'en-tête jusqu'à ce qu'un
	caractère de valeur décimale 32 soit rencontré (le plus souvent
	un espace ou une fin de ligne).
    

        
    Server Hostname
    
        
    Le nom DNS ou l'adresse IP fourni dans la ligne de commande.
    

        
    Server Port
    
        
    Le port auquel ab est connecté. Si la ligne de commande ne
	spécifie aucun port, le port par défaut sera 80 pour http et 443

    Document Length
    
        
    Il s'agit de la taille en octets du premier document renvoyé
	avec succès. Si la taille du document est modifiée au cours
	du test, la réponse est considérée comme une erreur.
    

        
    Concurrency Level
    
        
    Le nombre de clients simultanés utilisés au cours du test.
    

        
    Time taken for tests
    
        
    Il s'agit du temps écoulé entre le moment de la première
	connexion au socket et la réception de la dernière
	réponse.
    

        
    Complete requests
    
        
    Le nombre de réponses reçues avec succès.
    

        
    Failed requests
    
        
    Le nombre de requêtes considérées comme erronées. Si ce
	nombre est différent de 0, une ligne supplémentaire indiquera le
	nombre de requêtes ayant échoué suite à un problème de
	connexion, de lecture, de taille de contenu erronée ou
	d'exceptions.
    

        
    Write errors

    Le nombre de connexions promues à l'état de connexions
	persistantes.
    

        
    Total body sent
    
        
    Si le test a été configuré dans ce sens, il s'agit du nombre
	total d'octets envoyés au cours du test. Ce champ est omis si le
	test ne prévoyait pas d'envoi de corps.
    

        
    Total transferred
    
        
    Le nombre total d'octets reçus du serveur. Ce nombre
	correspond à peu près au nombre d'octets envoyés sur la ligne.
    

        
    HTML transferred
    
        
    Le nombre total d'octets utiles (contenus) reçus du serveur.
	Ce nombre n'inclut pas les octets correspondant aux en-têtes
	HTTP.
    

        
    Requests per second
    
        
    Il s'agit du nombre de requêtes par seconde. Il correspond
	au nombre de requêtes divisé par la durée totale du traitement.
    

        
    Time per request
    
        
    La durée moyenne du traitement d'une requête. La première
	valeur est calculée selon la formule concurrency *
	timetaken * 1000 / done, alors que la seconde valeur est
	calculée selon la formule timetaken * 1000 / done.
    

        
    Transfer rate
    
        
    Le taux de transfert calculé selon la formule
	totalread / 1024 / timetaken.
    
    
    

    top
    

    

    Bogues
    
    
    De nombreux tampons de taille fixe sont déclarés statiquement.
    Combiné avec l'interprétation poussive des arguments de la ligne de
    commande, les en-têtes de réponse du serveur et autres entrées
    externes, ceci peut vous affecter.
    

    
    HTTP/1.x n'est pas complètement implémenté ; seules certaines
    formes de réponses 'attendues' sont acceptées. L'utilisation
    relativement intense de strstr(3) provoque un affichage
    en tête de profil, ce qui peut faire croire à un problème de
    performances ; en d'autres termes, vous mesurez les performances de
    ab plutôt que celles du serveur.

    htcacheclean permet de maintenir la taille de
    l'espace de stockage réservé à mod_disk_cache en
    dessous d'une limite de taille donnée ou d'inodes utilisés. Cet
    utilitaire peut s'exécuter
    soit manuellement, soit en mode démon. Lorsqu'il fonctionne en mode
    démon, il se met en attente en arrière-plan et recherche à
    intervalles réguliers dans le répertoire du cache les contenus à
    supprimer. Pour arrêter proprement le démon, vous pouvez lui envoyer
    un signal TERM ou INT. Lorsqu'il est lancé manuellement, une
    recherche des contenus du cache qui peuvent être supprimés est
    effectuée une seule fois. Si une ou plusieurs URLs sont spécifiées,
    chacune d'entre elles sera supprimée du cache, si elle est présente.

    Options
    
    
    
    
    -dintervalle
    
    
    Configure en mode démon et planifie le nettoyage du cache toutes
    les intervalle minutes. Cette option et les options
    -D, -v et -r s'excluent
    mutuellement. Pour arrêter le démon proprement, il suffit de lui
    envoyer un signal SIGTERM ou SIGINT.
    

    
    -D
    
    
    Le programme s'exécute mais ne supprime aucun contenu ("dry run"). Cette
    option et l'option -d s'excluent mutuellement. Si ce mode
    est combiné avec la suppression des répertoires avec
    -t, les inodes signalés comme supprimés dans les
    statistiques ne peuvent pas prendre en compte les répertoires
    supprimés, et seront marqués en tant qu'estimation.
    

    
    -v
    
    
    Exécution verbeuse et affichage de statistiques. Cette
    option et l'option -d s'excluent mutuellement.
    

    
    -r
    
    
    Nettoyage en profondeur. Le serveur web Apache doit être arrêté
    (dans le cas contraire, il risque de rester des déchets dans le
    cache). Cette option implique l'option -t et s'exclue
    mutuellement avec l'option -d.
    

    
    -n
    
    
    Exécution en retrait. L'exécution du programme est ralentie en
    faveur des autres processus. htcacheclean s'interrompt
    de temps en temps de façon à ce que a) les entrées/sorties disque
    soient retardées et b) que le noyau puisse mettre ce temps
    processeur à disposition des autres processus.
    

    
    -t
    
    
    Supprime tous les répertoires vides. Par défaut, seuls les
    fichiers sont supprimés du cache ; avec certaines configurations,
    cependant, un grand nombre de répertoires sont créés et méritent que
    l'on y prête attention. Si votre configuration nécessite un grand
    nombre de répertoires, au point que le remplissage de la table
    d'inodes ou d'allocation de fichiers puisse poser problème,
    l'utilisation de cette option est conseillée.
    

    
    -pchemin
    
    
    Définit chemin comme répertoire racine du cache sur
    disque. Cette valeur doit correspondre à celle spécifiée par la
    directive CacheRoot.
    

    
    -Pfichier-pid
    
    
    Permet de spécifier fichier-pid comme nom du fichier
    dans le lequel sera enregistré l'identifiant du processus en mode
    démon.
    

    
    -Rround
    
    
    Permet de spécifier le plus petit commun multiple de la taille
    du cache, afin de tenir compte de la taille des blocs. Définir ce
    paramètre à la taille d'un bloc de la partition du cache.
    

    
    -llimite
    
    
    Définit limite comme la taille maximale du cache sur
    disque. La valeur s'exprime par défaut en octets (ou en ajoutant le
    suffixe B à la valeur). Ajoutez le suffixe
    K pour Ko, M pour Mo ou G pour
    Go.
    

    
    -Llimite
    
    
    Spécifie limite comme la limite totale en inodes du cache
    disque. Là aussi, on peut ajouter le suffixe K pour Ko,
    M pour Mo ou G pour Go.
    

    
    -i
    
    
    Exécution intelligente. Le programme ne s'exécute que lorsque le
    cache sur disque a été modifié. Cette option ne peut s'utiliser
    qu'avec l'option -d.
    

    
    -a
    
    
    Affiche la liste des URLs actuellement stockées dans le cache.
    Les variantes de la même URL seront listées une seule fois par
    variante.
    

    
    -A
    
    
    Affiche la liste des URLs actuellement stockées dans le cache,
    ainsi que leurs attributs dans l'ordre suivant : url, header size,
    body size, status, entity version, date, expiry, request time,
    response time, body present, head request.
    
    
    

    top
    

    

    Suppression d'une URL particulière
    
    
    Si une ou plusieurs URLs sont passées en argument à
    htcacheclean, chacune d'entre elles sera supprimée du
    cache. S'il existe plusieurs variantes de ces URLs, elles seront
    toutes supprimées.
    

    
    Lorsqu'une URL mandatée en inverse doit être supprimée, l'URL
    effective est construite à partir de l'en-tête
    Host, du port, du
    chemin et de la requête. Notez que
    le '?' doit toujours être spécifié explicitement dans l'URL, qu'une
    chaîne de paramètres soit présente ou non. Par exemple, pour
    supprimer le chemin / du serveur
    localhost, l'URL devra être spécifiée comme suit :
    http://localhost:80/?.
    


    top
    

    

    Affichage des URLs présentes dans le cache
    
    
    Les options -a ou -A permettent
    d'afficher les URLs présentes dans le cache telles qu'elles s'y
    trouvent, une URL par ligne. L'option -A affiche
    l'entrée du cache complète pour chaque URL, avec ses différents
    champs dans l'ordre suivant :
    

    
    
        
    url
    L'URL de l'entrée considérée.
    
        
    header size
    La taille de l'en-tête en octets.
    
        
    body size
    La taille du corps en octets.
    
        
    status
    Etat de la réponse en cache.
    
        
    entity version
    Le nombre de fois que cette entrée a
	été revalidée sans être effacée.
    
        
    date
    Date de la réponse.
    
        
    expiry
    Date d'expiration de la réponse.
    
        
    request time
    Date du début de la requête.
    
        
    response time
    Date de la fin de la requête.
    
        
    body present
    Ce champ contient la valeur 0 si aucun
	corps n'est stocké avec cette requête, 1 dans le cas contraire.
    
        
    head request
    Ce champ contient la valeur 1 si
	l'entrée comporte une requête HEAD en cache sans corps, 0 dans
	le cas contraire.
    
    
    


    top
    

    

    Valeur renvoyée
    
    
    htcacheclean renvoie zéro ("true") si toutes les
    opérations se sont déroulées normalement, et 1 dans le
    cas contraire. Si une URL est spécifiée, et si cette URL était
    présente dans le cache et a été supprimée avec succès,
    htcacheclean renvoie 0, et 2
    dans le cas contraire. Si une erreur est survenue au cours de la
    suppression de l'URL, htcacheclean renvoie
    1.

    configure betiği, Apache HTTP Sunucusunun kaynak kodlarını
      belli bir platform için yapılandırmakta ve derlemekte kullanılır.
      Sunucuyu kişisel gereksinimlerinize uygun şekilde derlemek için çeşitli
      seçeneklere sahiptir.
    

    
    Bu betik Apache HTTP Sunucusu kaynak paketinin kök dizininde bulunur ve
      sadece Unix ve benzeri sistemlerde kullanılabilir. Kaynak paketinin
      diğer platformalarda yapılandırılması ve derlenmesi hakkında bilgi
      edinmek için platform belgelerine bakınız.

    Komut Satırı
    
    
    configure betiğini kaynak paketinin kök dizininden başka
      bir yere kopyalayıp çalıştırmamalısınız.
    

    
    ./configure [seçenek]...
      [değişken=değer]...
    

    
    CC, CFLAGS gibi ortam değişkenlerini
      değişken=değer atamaları biçiminde
      kullanabilirsiniz. Kullanışlı değişkenlerin bazıları aşağıda açıklanmıştır.
    

    top
    

    

    Seçenekler
    
  

  
    Yapılandırma seçenekleri
    

    
    Aşağıdaki seçenekler configure betiğinin kendi davranışını
      belirlemekte kullanılır.
    

    
    
      
    -C
    
      
    --config-cache
    
      
    --cache-file=config.cache için bir kısaltmadır.
    

      
    --cache-file=dosya
    
      
    Sınama sonuçları dosya dosyasında saklanır.
        Bu seçenek açıkça belirtilmedikçe işlevsizdir.
    

      
    -h
    
      
    --help [short|recursive]
    
      
    Yardım metnini basar ve çıkar. short değeriyle sadece
        bu pakete özgü seçenekler listelenir. recursive değeriyle
        ise paketin içindeki tüm paketler için kısa bir yardım metni
        basılır.
    

      
    -n
    
      
    --no-create
    
      
    configure betiği normal olarak çalışır fakat herhangi
        bir çıktı dosyası üretmez. Derleme için Makefile
        dosyalarını üretmeksizin sınamaların sonuçlarını görmek için
        yararlıdır.
    

      
    -q
    
      
    --quiet
    
      
    Yapılandırma sürecinde checking ... iletilerini basmaz.
      
    

      
    --srcdir=dizin
    
      
    dizin dizinini kaynak dosyaları dizini olarak
        tanımlar. configure betiğinin bulunduğu dizin veya bir
        üst dizin öntanımlıdır.
    

      
    --silent
    
      
    --quiet ile aynı.
    

      
    -V
    
      
    --version
    
      
    Telif hakkı bilgilerini gösterir ve çıkar.
    
    
    
  

  
    Kurulum dizinleri
    

    
    Bu seçenekler kurulum dizinlerini tanımlar. Kurulum dizinleri seçilmiş
      yerleşime bağımlıdır.
    

    
    
      
    --prefix=PREFIX
    
      
    Mimariden bağımsız dosyalar PREFIX dizininin
        altına kurulur. /usr/local/apache2 öntanımlı kurulum
        dizinidir.
    

      
    --exec-prefix=EPREFIX
    
      
    Mimariye bağımlı dosyalar EPREFIX dizininin
        altına kurulur. Bunun için PREFIX dizini
        öntanımlı kurulum dizinidir.
    
    
    

    
    Öntanımlı olarak, make install tüm dosyaların
      /usr/local/apache2/bin, /usr/local/apache2/lib
      gibi dizinlere kurulmasını sağlar. Kurulum dizini önekini örneğin,
      --prefix=$HOME şeklinde belirterek kurulumun başka bir yere
      yapılmasını sağlayabilirsiniz.
    

    
    Bir dizin yerleşimi tanımlamak
    
      
    
        
    --enable-layout=LAYOUT
    
        
    Kaynak kodu ve derleme betikleri kurulum ağacının
          LAYOUT yerleşimine dayalı olduğu varsayımıyla
          yapılandırılır. Bu seçenek sayesinde Apache HTTP Sunucusu kurulumu
          içinde her dosya türü için farklı bir yer belirleyebilirsiniz.
          config.layout dosyasında böyle yapılandırma örnekleri
          vardır. Örnekleri izleyerek kendi yapılandırmanızı
          oluşturabilirsiniz. Bu dosyada örneğin FOO isimli
          yerleşim <Layout FOO>...</Layout> bölümü
          içinde düzenlenmiştir ve her yerleşim için böyle ayrı bir bölüm
          vardır. Öntanımlı yerleşim Apache’dir.
    
      
    
    

    
    Kurulum dizinlerinde ince ayar
    
      

      
    Kurulum dizinlerini daha iyi denetim altında tutmak için aşağıdaki
        seçenekler kullanılır. Lütfen, dizin öntanımlılarının
        autoconf tarafından tanımlandığına ve seçilen yerleşim
        ayarlarının bunları yerini aldığına dikkat ediniz.
    

      
    
        
        
    --bindir=dizin
    
        
    Kullanıcı tarafından çalıştırılabilen dosyalar
          dizin dizinine kurulur. Bunlar
          htpasswd, dbmmanage gibi site
          yönetimi için yararlı destek programlarıdır. Öntanımlı olarak bu
          dosyalar EPREFIX/bin dizinine kurulur.
    

        
    --datadir=dizin
    
        
    Mimariden bağımsız salt okunur veriler dizin
          dizinine kurulur. Bunların öntanımlı kurulum dizini
          PREFIX/share dizinidir. Bu seçenek
          autoconf tarafından atanır ve şimdilik
          kullanılmamıştır.
    

        
    --includedir=dizin
    
        
    C başlık dosyaları dizin dizinine kurulur.
          Bunların öntanımlı kurulum dizini
          PREFIX/include dizinidir.
    

        
    --infodir=dizin
    
        
    Info belgeleri dizin dizinine kurulur.
          Bunların öntanımlı kurulum dizini
          PREFIX/info dizinidir. Bu seçenek şimdilik
          kullanılmamıştır.
    

        
    --libdir=dizin
    
        
    Nesne kod kütüphaneleri dizin dizinine
          kurulur. Bunların öntanımlı kurulum dizini
          PREFIX/lib dizinidir.
    

        
    --libexecdir=dizin
    
        
    Paylaşımlı modüller gibi program dosyaları
          dizin dizinine kurulur. Öntanımlı olarak
          libexecdir bu dizini
          EPREFIX/modules olarak tanımlar.
    

        
    --localstatedir=dizin
    
        
    Düzenlenebilir tek makinelik veri dizin
          dizinine kurulur. Öntanımlı olarak localstatedir bu
          dizini PREFIX/var olarak tanımlar. Bu
          seçenek autoconf tarafından atanır ve şimdilik
          kullanılmamıştır.
    

        
    --mandir=dizin
    
        
    Kılavuz sayfaları dizin dizinine kurulur.
          Öntanımlı olarak mandir bu dizini
          EPREFIX/man olarak tanımlar.
    

        
    --oldincludedir=dizin
    
        
    GCC harici C başlık dosyaları dizin dizinine
          kurulur. Öntanımlı olarak oldincludedir bu dizini
          /usr/include olarak tanımlar. Bu seçenek
          autoconf tarafından atanır ve şimdilik
          kullanılmamıştır.
    

        
    --sbindir=dizin
    
        
    Sistem yöneticisi tarafından kullanılabilen programlar
          dizin dizinine kurulur. Bunlar
          httpd, apachectl,
          suexec gibi Apache HTTP Sunucusunu çalıştırmak
          için gereken programlardır. Öntanımlı olarak sbindir bu
          dizini EPREFIX/sbin olarak tanımlar.
    

        
    --sharedstatedir=dizin
    
        
    Mimariye bağımlı düzenlenebilir veriler
          dizin dizinine kurulur. Öntanımlı olarak
          sharedstatedir bu dizini
          PREFIX/com olarak tanımlar. Bu seçenek
          autoconf tarafından atanır ve şimdilik
          kullanılmamıştır.
    

        
    --sysconfdir=dizin
    
        
    httpd.conf, mime.types gibi tek
          makinelik salt okunur sunucu yapılandırma dosyaları
          dizin dizinine kurulur. Öntanımlı olarak
          sysconfdir bu dizini
          PREFIX/conf olarak tanımlar.
    
      
    
    
  

  
    Sistem türleri
    

    
    Bu seçenekleri Apache HTTP Sunucusunu başka bir platformda çalıştırmak
      üzere çapraz derleme yaparken kullanılır. Normal durumlarda sunucu
      derlendiği platformda çalıştırıldığından bu seçenekler kullanılmaz.
    

    
    
      
    --build=derleme-ortamı
    
      
    Derleme araçlarının derleneceği sistemin sistem türünü tanımlar.
        config.guess betiği ile elde edilen sonuç
        öntanımlıdır.
    

      
    --host=çalışma-ortamı
    
      
    Sunucunun çalışacağı sistemin sistem türünü tanımlar. Öntanımlı
        sistem türü derleme-ortamı’dır.
    

      
    --target=hedef-ortam
    
      
    Derleyicileri hedef-ortam sistem türü için
        yapılandırır. Öntanımlı sistem türü
        çalışma-ortamı’dır. Bu seçenek
        autoconf tarafından atanır ve Apache HTTP Sunucusu için
        gerekli değildir.
    
    
    
  

  
    Seçimlik özellikler
    

    
    Bu seçenekler HTTP sunucunuzun sahip olmasını istediğiniz özelliklerin
      hassas olarak ayarlanmasını sağlar.
    

    
    Genel sözdizimi
    
      
    Bir özelliği etkin kılmak veya iptal etmek için genellikle şu
        sözdizimi kullanılır:
    

      
    
        
    --disable-özellik
    
        
    Sunucu özellik özelliğine sahip olmaz. Bu
          seçenek--enable-özellik=no seçeneğine
          eşdeğerdir.
    

        
    --enable-özellik[=değer]
    
        
    Sunucu özellik özelliğine sahip olur.
          değer belirtilmediği takdirde
          yes (evet) öntanımlıdır.
    

        
    --enable-modül=shared
    
        
    Belirtilen modül DSO modülü olarak derlenir. Öntanımlı olarak
          etkin modüller devingen ilintilenir.
    

        
    --enable-modül=static
    
        
    Belirtilen modül durağan ilintilenir.
    
      
    

      
    Bilginize
    
      
    --enable-filanca seçeneğinin varlığı
        configure betiğinin filanca diye
        bir modül var olmasa bile bundan şikayetçi olmasına sebep olmaz. Bu
        bakımdan dikkatli olunuz.
    
      
    
    

    
    Derlenecek modüllerin seçimi
    
      
    Modüllerin çoğu öntanımlı olarak derlenir ve ya açıkça iptal edilmek
        ya da few anahtar sözcüğü
        kullanılarak kaldırılmak zorunda kalınır (ayrıntılar için
        --enable-modules, --enable-mods-shared ve
        --enable-mods-static seçeneklerine bakın). Bir grubu 
        tamamen kaldırmak için --enable-modules=none gerekir.
    

        
    Öntanımlı olarak derlenmeyenler ise ya açıkça etkin kılınmak ya da
          all veya reallyall anahtar sözcükleriyle
          kullanılabilir yapılmak zorunda kalınır.
    

        
    Hangi modüllerin öntanımlı olarak derlendiğini öğrenmek için
          ./configure -h veya ./configure --help
          komutunu çalıştırın ve çıktıdaki Optional Features
          bölümüne bakın. Örnek olarak, mod_example1 ve
          mod_example2 modülleriyle ilgilendiğinizi
          varsayalım:
    

        
    Optional Features:
  ...
  --disable-example1     example module 1
  --enable-example2      example module 2
  ...
    

        
    Burada, mod_example1 öntanımlı olarak etkindir ve
          derlenmemesini istiyorsanız --disable-example1
          seçeneğini kullanmalısınız. mod_example2 ise öntanımlı
          olarak derlenmemektedir ve derlenmesini istiyorsanız
          --enable-example2 seçeneğini kullanmalısınız.
    
    

    
    Çok Süreçlilik Modülleri
    
      
    Çok Süreçlilik Modülleri veya MPM'ler
        sunucunun temel davranışını belirler. Sunucuya yüklenebilecek azami MPM
        sayısı birdir. Kullanılabilecek modüller modül
        dizininde listelenmiştir.
    

      
    MPM'ler devingen yükleme için DSO olarak derlenebileceği gibi
        sunucuyla duruk olarak da ilintilenebilir ve bunlar aşağıdaki
        seçeneklerle etkin kılınır:
    

      
    
        
    --with-mpm=MPM
    
        
    
          
    Sunucu için öntanımlı MPM'i seçer. MPM'ler DSO modülleri olarak
            derleniyorsa (bak --enable-mpms-shared), bu seçenek
            öntanımlı yapılandırma dosyasında yüklenecek MPM'i seçer. Aksi
            takdirde, sunucuyla duruk olarak ilintilenecek, kullanılabilir tek
            MPM'i seçer.
    

          
    Bu seçenek belirtilmezse, işletim sisteminiz için
            öntanımlı olan MPM seçilir.
    
        
    

       
    --enable-mpms-shared=MPM-LISTESİ
    
        
    
          
    MPM'leri devingen paylaşımlı modül olarak etkinleştirir.
            LoadModule yönergesi
            kullanılarak bu modüllerden biri devingen olarak yüklenmelidir.
    

          
    MPM-LISTESİ MPM'lerin aralarına boşluk bırakılarak ve
            tamamı tek tırnaklarla sarmalanarak oluşturulmuş bir listesidir.
            Örnek:
    

          
    
            --enable-mpms-shared='prefork worker'
          
    

          
    Ek olarak, kullandığınız platformda devingen yüklemeyi destekleyen
            ve DSO modülü olarak derlenmiş tüm modülleri seçmek için
            all anahtar sözcüğünü de kullanabilirsiniz. Örnek:
    

            
    
            --enable-mpms-shared=all
          
    
       
    
     
    
    

    
    Üçüncü parti modüller
    
      
    Üçüncü parti modülleri etkin kılmak için şu seçenekler kullanılır:
    

      
    
        
    --with-module=modül-türü:modül-dosyası[,modül-türü:modül-dosyası]
    
        
    Durağan ilintili modüller listesine belirtilen modülleri ekler.
          Modül kaynak dosyası modül-dosyası, önce
          Apache HTTP Sunucusu kaynak ağacı altında
          modules/modül-türü alt dizininde aranır.
          Modül orada değilse configure  betiği
          modül-dosyası ile bir mutlak dosya yolu
          belirtildiği varsayımıyla kaynak dosyasını
          modül-türü alt dizinine kopyalamaya çalışır.
          Alt dizin mevcut değilse oluşturulur ve içine standart bir
          Makefile.in yerleştirilir.
    

        
    Bu seçenek tek kaynak dosyasından oluşan küçük harici modülleri
          eklemek için yararlıdır. Daha karmaşık modüller için modül üreticisi
          tarafından sağlanan belgelere bakınız.
    

        
    Bilginize
    
          
    Durağan ilintili modüller yerine bir DSO modülü derlemek
            isterseniz apxs programını kullanınız.
    
        
    
        
    
      
    
    

    
    Kümeleme seçenekleri ve diğerleri
    
      
    
        
    --enable-maintainer-mode
    
        
    Hata ayıklama iletileri ve derleme sırasındaki uyarıların
          gösterilmesi etkin kılınır ve derlenmiş tüm modüller yüklenir.
    

        
    --enable-mods-shared=modül-listesi
    
        
    
          
    Etkinleştirilip devingen paylaşımlı modül olarak derlenecek
            modüllerin listesi belirtilir. Yani, bu modüller LoadModule yönergesi kullanılarak
            devingen olarak yüklenir.
    

          
    modül-listesi tırnak içine alınmış boşluk
            ayraçlı modül isimleri listesidir. Modül isimleri önlerindeki
            mod_ öneki olmaksızın belirtilirler. Örnek:
    

          
    
            --enable-mods-shared='headers rewrite dav'
          
    

          
    modül-listesi yerine
            reallyall, all, most ve 
            few anahtar sözcükleri de belirtilebilir. Örneğin,
    

          
    
            --enable-mods-shared=most
          
    

          
    seçeneği ile çoğu modül DSO modülü olarak derlenir,
    

          
    
            --enable-mods-shared=few
          
    

          
    seçeneği ile sadece en temel modüller derlenir.
    

          
    most öntanımlıdır.
    

          
    Seçilen modüller için LoadModule yönergeleri ana yapılandırma dosyasında
            kendiliğinden üretilir. Öntanımlı olarak, --enable-foo
            yapılandıma seçeneği ile açıkça seçilen modüller ve gerekli olanlar
            dışında kalan LoadModule yönergeleri açıklama haline
            getirilir. Yüklü modülleri httpd.conf dosyasındaki
            LoadModule yönergelerini
            etkin kılarak veya açıklama haline getirerek değiştirebilirsiniz.
            LoadModule yönergelerine ek
            olarak, derlenmiş tüm modüller
            --enable-load-all-modules yapılandırma seçeneği ile de
            etkinleştirilebilir.
    

        
    --enable-mods-static=modül-listesi
    
        
    Bu seçenek modülleri devingen değil de durağan ilintilemek dışında
          --enable-mods-shared seçeneğine benzer. Yani bu
          modüller httpd çalıştırılır çalıştırılmaz etkin
          olurlar. Yüklenmeleri için LoadModule yönergesine ihtiyaçları
          yoktur.
    

        
    --enable-modules=MODULE-LIST
    
        
    Bu seçenek --enable-mods-shared gibi davranır ve ek
          olarak belirtilen modülleri devingen olarak ilintiler.Özel
          none anahtar sözcüğü tüm modüllerin derlenmesini iptal
          eder.
    

        
    --enable-v4-mapped
    
        
    IPv6 soketlierinin IPv4 bağlantılar üzerinde kullanılması mümkün
          olur.
    

        
    --with-port=port
    
        
    Bu seçenek httpd'nin dinleyeceği portu
          belirler. Bu port httpd.conf yapılandırma dosyası
          üretilirken kullanılır. 80. port öntanımlıdır.
    

        
    --with-program-name
    
        
    Öntanımlı olan httpd yerine başka bir çalıştırabilir
          ismi tanımlar.
    
      
    
    
  

  
    Seçimlik paketler
    
    
    Buradaki seçenekler seçimlik paketleri tanımlamak için kullanılır.
    

    
    Genel sözdizimi
    
      
    Bir seçimlik paketi tanımlamak için genellikle şöyle bir sözdizimi
        kullanılır:
    

      
    
        
    --with-paket[=değer]
    
        
    paket paketi kullanılır. Öntanımlı
          değer yes’tir.
    

        
    --without-paket
    
        
    paket paketi kullanılmaz. Öntanımlı
          değer no’dur. Bu seçenek
          autoconf tarafından sağlanmıştır ve Apache HTTP
          Sunucusu için pek yararlı değildir.
    
      
    
    

    

    
    Özel paketler
    
      
    
        
    --with-apr=dizin|dosya
    
        
    Apache Taşınabilir Arayüzü (APR)
          httpd kaynak paketinin bir parçası olup HTTP Sunucu ile birlikte
          derlenir. Eğer kendi kurulu APR’nizi kullanmak isterseniz bunu
          configure betiğine apr-config betiğinin
          yolunu belirterek ifade edebilirsiniz. Kurulu APR için bid dizin,
          dosya ismi veya mutlak dosya yolu belirtebilirsiniz.
          apr-config ya belirttiğiniz dizinde ya da
          bin alt dizininde bulunmalıdır.
    

        
    --with-apr-util=dizin|dosya
    
        
    Apache Taşınabilir Arayüzü Araçları (APU) httpd kaynak paketinin
          bir parçası olup HTTP Sunucu ile birlikte derlenir. Eğer kendi
          kurulu APU’nuzu kullanmak isterseniz bunu configure
          betiğine apu-config betiğinin yolunu belirterek ifade
          edebilirsiniz. Kurulu APR için bir dizin, dosya ismi veya mutlak
          dosya yolu belirtebilirsiniz. apr-config ya
          belirttiğiniz dizinde ya da bin alt dizininde
          bulunmalıdır.
    

        
    --with-ssl=dizin
    
        
    mod_ssl modülü etkinse configure
          betiği kurulu bir OpenSSL arayacaktır. Kendi SSL/TLS kurulumunuzun
          yolunu bu seçenekle belirtebilirsiniz.
    

        
    --with-z=dizin
    
        
    Yapılandırmanız gerektirdiği takdirde (örneğin,
          mod_deflate etkinse) configure betiği
          kurulu zlib kütüphanesinin yerini tespit etmeye
          çalışacaktır. Kendi sıkıştırma kütüphanenizin yerini bu seçenekle
          belirtebilirsiniz.
    
      
    

      
    Apache HTTP Sunucusunun çeşitli bölümleri,
        mod_authn_dbm modülü ve mod_rewrite
        modülünün RewriteMap
        yönergesi bilgilere erişimi hızlandırmak için basit anahtar/değer
        veritabanları kullanırlar. SDBM, APU içinde mevcut olduğundan bu
        veritabanı her zaman kullanılabilir durumdadır. Eğer başka veritabanı
        türleri kullanmak isterseniz aşağıdaki seçeneklerle bunları etkin
        kılabilirsiniz:
    

      
    
        
    --with-gdbm[=dizin-yolu]
    
        
    Bir dizin-yolu belirtilmemişse
          configure betiği GNU DBM kurulumunun kütüphanelerini ve
          başlık dosyalarını bulunması olası yerlerde arar.  Bir
          dizin-yolu belirtilmişse
          configure betiği kurulumun kütüphanelerini
          dizin-yolu/lib altında, başlık dosyalarını
          ise dizin-yolu/include altında arayacaktır.
          Bundan başka, başlık ve kütüphane dosyalarının bulundukları yerler
          iki nokta imi ile ayrılarak dizin-yolu
          olarak belirtilebilir.
    

        
    --with-ndbm[=dizin-yolu]
    
        
    New DBM kurulumunu araştırması dışında --with-gdbm
          seçeneği gibidir.
    

        
    --with-berkeley-db[=dizin-yolu]
    
        
    Berkeley DB kurulumunu araştırması dışında
          --with-gdbm seçeneği gibidir.
    
      
    

      
    Bilginize
    
        
    DBM seçenekleri APU tarafından sağlanmış olup onun yapılandırma
          betiğine aktarılır. Bu seçenekler --with-apr-util
          seçeneği ile tanımlanmış bir kurulu APU varsa kullanışlı olur.
    
        
    HTTP sunucunuz ile birlikte birden fazla DBM gerçeklenimi
          kullanabilirsiniz. Kullanılacak DBM türünü her zaman çalışma anı
          yapılandırmanızla yapılandırabilirsiniz.
    
      
    
    
  

  
    Destek programları için seçenekler
    
    
    
      
    --enable-static-support
    
      
    Destek programlarını durağan ilintili olarak derler. Yani
        çalıştırılabilirin kullandığı bütün kütüphaneler kodla
        bütünleştirilir. Bu seçenek belirtilmedikçe destek programları daima
        devingen ilintili olarak derlenir.
    

      
    --enable-suexec
    
      
    Çatallanan sürecin kullanıcı ve grup kimliklerinin
        değiştirilebilmesini sağlayan suexec programının
        kullanımını etkinleştirir. Sunucunuz üzerinde suid biti
        etkinleştirilmiş bir program çalıştırmanın sistem güvenliğinde
        yaratacağı sorunlar hakkında bir fikriniz yoksa bu seçeneği
        etkinleştirmeyin. suexec yapılandırma
        seçenekleri aşağıda açıklanmıştır.
    
    
    

    
    Tek bir destek programını aşağıdaki seçenekleri kullanarak bir durağan

    Options
    
    
    
    
    -A auth-username:password
    
    
    Supply BASIC Authentication credentials to the server. The username and
    password are separated by a single : and sent on the wire
    base64 encoded. The string is sent regardless of whether the server needs
    it (i.e., has sent an 401  authentication needed).
    

    
    -b windowsize
    
    
    Size of TCP send/receive buffer, in bytes.
    

    
    -B local-address
    
    
    Address to bind to when making outgoing connections.
    

    
    -c concurrency
    
    
    Number of multiple requests to perform at a time. Default is one
    request at a time.
    

    
    -C cookie-name=value
    
    
    Add a Cookie: line to the request. The  argument  is
    typically in the form of a name=value
    pair. This field is repeatable.
    

    
    -d
    
    
    Do not display the "percentage served within XX [ms] table". (legacy
    support).
    

    
    -e csv-file
    
    
    Write a Comma separated value (CSV) file which contains for each
    percentage (from 1% to 100%) the time (in milliseconds) it took to serve
    that percentage of the requests. This is usually more useful than the
    'gnuplot' file; as the results are already 'binned'.
    

    
    -E client-certificate-file
    
    
    When connecting to an SSL website, use the provided client certificate
    in PEM format to authenticate with the server. The file is expected to
    contain the client certificate, followed by intermediate certificates,
    followed by the private key. Available in 2.4.36 and later.
    

    
    -f protocol
    
    
    Specify SSL/TLS protocol (SSL2, SSL3, TLS1, TLS1.1, TLS1.2, or ALL).
    TLS1.1 and TLS1.2 support available in 2.4.4 and later.
    

    
    -g gnuplot-file
    
    
    Write all measured values out as a 'gnuplot' or TSV (Tab separate
    values) file. This file can easily be imported into packages like Gnuplot,
    IDL, Mathematica, Igor or even Excel. The labels are on the first line of
    the file. 
    

    
    -h
    
    
    Display usage information.
    

    
    -H custom-header
    
    
    Append extra headers to the request.  The  argument  is typically in
    the form of a valid header line, containing a colon-separated field-value
    pair (i.e., "Accept-Encoding: zip/zop;8bit").
    

    
    -i
    
    
    Do HEAD requests instead of GET.
    

    
    -k
    
    
    Enable the HTTP KeepAlive feature, i.e., perform multiple
    requests within one HTTP session. Default is no KeepAlive.
    

    
    -l
    
    
    Do not report errors if the length of the responses is not constant. This 
    can be useful for dynamic pages.
    Available in 2.4.7 and later.
    
    

    
    -m HTTP-method
    
    
    Custom HTTP method for the requests.
    Available in 2.4.10 and later.
    

    
    -n requests
    
    
    Number of requests to perform for the benchmarking session. The default
    is to just perform a single request which usually leads to
    non-representative benchmarking results.
    

    
    -p POST-file
    
    
    File containing data to POST.  Remember to also set -T.
    

    
    -P proxy-auth-username:password
    
    
    Supply BASIC Authentication credentials to a proxy en-route. The
    username and password are separated by a single : and sent on
    the  wire base64 encoded. The string is sent regardless of whether the
    proxy needs it (i.e., has  sent an 407 proxy authentication
    needed).
    

    
    -q
    
    
    When processing more than 150 requests, ab outputs a
    progress count on stderr every 10% or 100 requests or so. The
    -q flag will suppress these messages.
    

    
    -r
    
    
    Don't exit on socket receive errors.
    

    
    -s timeout
    
    
    Maximum number of seconds to wait before the socket times out.
    Default is 30 seconds.
    Available in 2.4.4 and later.
    

    
    -S
    
    
    Do not display the median and standard deviation values, nor display
    the warning/error messages when the average and median are more than
    one or two times the standard deviation apart. And default to the
    min/avg/max values. (legacy support).
    

    
    -t timelimit
    
    
    Maximum number of seconds to  spend  for  benchmarking. This implies a
    -n 50000 internally. Use this to benchmark the server within a
    fixed total amount of time. Per default there is no timelimit.
    

    
    -T content-type
    
    
    Content-type header to use for POST/PUT data, eg.
    application/x-www-form-urlencoded.
    Default is text/plain.
    

    
    -u PUT-file
    
    
    File containing data to PUT.  Remember to also set -T.
    

    
    -v verbosity
    
    
    Set verbosity level - 4 and above prints information on
    headers, 3 and above prints response codes (404, 200, etc.),
    2 and above prints warnings and info.
    

    
    -V
    
    
    Display version number and exit.
    

    
    -w
    
    
    Print out results in HTML tables. Default table is two columns wide,
    with a white background.
    

    
    -x <table>-attributes
    
    
    String to use as attributes for <table>. Attributes
    are inserted <table here >.
    

    
    -X proxy[:port]
    
    
    Use a proxy server for the requests.
    

    
    -y <tr>-attributes
    
    
    String to use as attributes for <tr>.
    

    
    -z <td>-attributes
    
    
    String to use as attributes for <td>.
    

    
    -Z ciphersuite
    
    
    Specify SSL/TLS cipher suite (See openssl ciphers)

    Output
    
    
    The following list describes the values returned by ab:
    
    

    
    
        
    Server Software
    
        
    The value, if any, returned in the server HTTP header
        of the first successful response. This includes all characters in the
        header from beginning to the point a character with decimal value of 32
        (most notably: a space or CR/LF) is detected.
    

        
    Server Hostname
    
        
    The DNS or IP address given on the command line
    

        
    Server Port
    
        
    The port to which ab is connecting. If no port is given on the
        command line, this will default to 80 for http and 443 for
        https.
    

        
    SSL/TLS Protocol
    
        
    The protocol parameters negotiated between the client and server.
        This will only be printed if SSL is used.
    

        
    Document Path
    
        
    The request URI parsed from the command line string.
    

        
    Document Length
    
        
    This is the size in bytes of the first successfully returned document.
        If the document length changes during testing, the response is
        considered an error.
    

        
    Concurrency Level
    
        
    The number of concurrent clients used during the test
    

        
    Time taken for tests
    
        
    This is the time taken from the moment the first socket connection
        is created to the moment the last response is received
    

        
    Complete requests
    
        
    The number of successful responses received
    

        
    Failed requests
    
        
    The number of requests that were considered a failure. If the
        number is greater than zero, another line will be printed showing the
        number of requests that failed due to connecting, reading, incorrect
        content length, or exceptions.
    

        
    Write errors
    
        
    The number of errors that failed during write (broken pipe).
    

        
    Non-2xx responses
    
        
    The number of responses that were not in the 200 series of response
        codes. If all responses were 200, this field is not printed.
    

        
    Keep-Alive requests
    
        
    The number of connections that resulted in Keep-Alive requests
    

        
    Total body sent
    
        
    If configured to send data as part of the test, this is the total
        number of bytes sent during the tests. This field is omitted if the test
        did not include a body to send.
    

        
    Total transferred
    
        
    The total number of bytes received from the server. This number
        is essentially the number of bytes sent over the wire.
    

        
    HTML transferred
    
        
    The total number of document bytes received from the server. This
        number excludes bytes received in HTTP headers
    

        
    Requests per second
    
        
    This is the number of requests per second. This value is the result
        of dividing the number of requests by the total time taken
    

        
    Time per request
    
        
    The average time spent per request. The first value is calculated
        with the formula concurrency * timetaken * 1000 / done
        while the second value is calculated with the formula
        timetaken * 1000 / done
    

        
    Transfer rate
    
        
    The rate of transfer as calculated by the formula
        totalread / 1024 / timetaken
    
    
    

    top
    

    

    Bugs
    
    
    There are various statically declared buffers of fixed length. Combined
    with the lazy parsing of the command line arguments, the response headers
    from the server and other external inputs, this might bite you.
    

    
    It does not implement HTTP/1.x fully; only accepts some 'expected' forms
    of responses. The rather heavy use of strstr(3) shows up top
    in profile, which might indicate a performance problem; i.e., you
    would measure the ab performance rather than the server's.

    suexec permet au serveur HTTP Apache de changer
     d'utilisateur avant d'exécuter un programme CGI. Pour ce faire, il
     doit être exécuté par root. A cet effet, comme le
     démon HTTP ne s'exécute en général pas en tant que
     root, l'exécutable suexec doit posséder
     le bit setuid et avoir comme propriétaire root. Seul
     root doit en posséder les droits en écriture.
    

     
    Pour plus d'informations à propos des concepts et du modèle de
     sécurité du programme suexec, veuillez vous reporter à sa
     documentation : http://httpd.apache.org/docs/2.4/suexec.html.

    logresolve is a post-processing program to
     resolve IP-addresses in Apache's access logfiles.  To minimize
     impact on your nameserver, logresolve has its very own internal
     hash-table cache.  This means that each IP number will only be
     looked up the first time it is found in the log file.
    

     
    Takes an Apache log file on standard input.  The IP addresses
     must be the first thing on each line and must be separated from
     the remainder of the line by a space.

    Options
    


    


    -s filename
    


    Specifies a filename to record statistics.
    


    -c
    


    This causes logresolve to apply some DNS checks:
after finding the hostname from the IP address, it looks up the IP
addresses for the hostname and checks that one of these matches the
original address.

    split-logfile - Split up multi-vhost logfiles
    

    

    Available Languages:  en  |
 fr 
    

    

    
    This perl script will take a combined Web server access log file and
    break its contents into separate files. It assumes that the first field of
    each line is the virtual host identity, put there using the "%v"
    variable in LogFormat.
    
    

    

    top
    

    

    Usage
    

    
    Create a log file with virtual host information in it:
    

    
    LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\"" combined_plus_vhost
CustomLog logs/access_log combined_plus_vhost
    


    
    Log files will be created, in the directory where you run the
    script, for each virtual host name that appears in the combined log file.
    These logfiles will named after the hostname, with a
    .log file extension.
    

    
    The combined log file is read from stdin. Records read will be appended
    to any existing log files.
    

    
    split-logfile < access_log

apxs - Utilitaire pour les extensions d'Apache - Serveur HTTP Apache Version 2.4

    Serveur HTTP Apache Version 2.4

    apxs - Utilitaire pour les extensions d'Apache
    

    

    Langues Disponibles:  en  |

 tr 
    

    

    
    apxs est un utilitaire permettant de compiler et
    d'installer des modules en tant qu'extensions du serveur HTTP
    Apache. A cet effet, un objet dynamique partagé (DSO) est compilé à
    partir d'un ou plusieurs fichiers sources ou objets et
    peut être chargé pendant l'exécution du serveur Apache via la
    directive LoadModule du
    module mod_so.
    

    
    Pour pouvoir utiliser ce mécanisme d'extensions, votre
    plate-forme doit supporter la fonctionnalité DSO, et votre binaire
    httpd Apache doit être compilé avec le module
    mod_so. Si ce n'est pas le cas, l'utilitaire
    apxs vous le signalera. Vous pouvez aussi vérifier
    vous-même ces prérequis en exécutant manuellement la commande :
    

    
    
      $ httpd -l
    
    

    
    Le module mod_so doit faire partie de la liste
    des modules affichée. Si ces prérequis sont présents, vous pouvez
    facilement étendre les fonctionnalités de votre serveur Apache en
    installant vos propres modules à l'aide de l'utilitaire
    apxs, via le mécanisme DSO :
    

    
    
      $ apxs -i -a -c mod_foo.c
    
      gcc -fpic -DSHARED_MODULE -I/chemin/vers/apache/include -c mod_foo.c
    
      ld -Bshareable -o mod_foo.so mod_foo.o
    
      cp mod_foo.so /chemin/vers/apache/modules/mod_foo.so
    
      chmod 755 /chemin/vers/apache/modules/mod_foo.so
    
      [activation du module `foo' dans /chemin/vers/apache/etc/httpd.conf]
    
      $ apachectl restart
    
      /chemin/vers/apache/sbin/apachectl restart: httpd not running, trying to start
    
      [Tue Mar 31 11:27:55 1998] [debug] mod_so.c(303): loaded module foo_module
    
      /chemin/vers/apache/sbin/apachectl restart: httpd started
    
      $ _
    
    

    
    Les arguments fichiers peuvent correspondre à un
    fichier source C (.c), un fichier objet (.o) ou même une archive de
    bibliothèques (.a). L'utilitaire apxs reconnaît
    automatiquement ces extensions et utilise automatiquement les
    fichiers source C pour la compilation, et les fichiers objets et
    archives pour l'édition de liens. Cependant, si vous utilisez des
    fichiers objets précompilés, assurez-vous que leur code soit
    indépendant de la position (PIC), afin de pouvoir les utiliser avec
    un objet partagé chargé dynamiquement. Avec GCC, par exemple, il
    vous suffit de toujours utiliser l'option de compilation
    -fpic. Pour les autres compilateurs C, consultez leur
    page de manuel, ou vérifiez les drapeaux qu'apxs
    utilise pour compiler les fichiers objets.
    

    
    Pour plus de détails à propos du support DSO dans Apache, lire la
    documentation du module mod_so, ou même, consultez
    le fichier source src/modules/standard/mod_so.c.

    Options courantes
    
      
    
      
    -n nom-module
    
      
    Définit explicitement le nom du module pour les options
      -i (install) et -g (génération de
      modèles). Utilisez cette option pour spécifier de manière
      explicite le nom du module. Pour l'option -g, cette
      option est nécessaire ; pour l'option -i,
      l'utilitaire apxs tente de déterminer le nom du
      module à partir des sources, ou (à défaut) en le déduisant du nom
      de fichier.
    
      
    
    

    
    Options de requête
    
      
    
      
    -q
    
      
    Effectue une requête à propos des variables et de
      l'environnement utilisés pour compiler httpd.
      Lorsqu'elle est invoquée sans paramètre requête, cette
      option affiche toutes les variables connues, ainsi que leurs
      valeurs. Le paramètre optionnel -v formate la liste
      affichée.

      
    Utilisez cette option pour déterminer manuellement les options
      utilisées pour compiler le binaire httpd qui chargera
      votre module. Ajoutez par exemple
    
      
    
        INC=-I`apxs -q INCLUDEDIR`
      
    

      
    dans vos propres Makefiles si vous devez accéder manuellement
      aux fichiers d'en-têtes C d'Apache.
    
      
    
    

    
    Options de configuration
    
      
    
      
    -S nom=valeur
    
      
    Cette option permet de modifier la configuration d'apxs
      décrite ci-dessus.
    
      
    
    

    
    Option de génération des
    modèles
    
      
    
      
    -g
    
      
    Cette option permet de générer un sous-répertoire
      nom (voir option -n) contenant deux
      fichiers : le premier fichier est un exemple de fichier source de
      module nommé mod_nom.c que l'on peut
      utiliser comme modèle pour créer ses propres modules, ou comme
      point de départ pour se familiariser avec le mécanisme apxs ; le
      second fichier est le Makefile correspondant
      facilitant la compilation et l'installation de ce module.
    
      
    
    
    
    Options de compilation DSO
    
      
    
      
    -c
    
      
    Cette option indique une opération de compilation. Tout
      d'abord, les fichiers sources (.c) spécifiés par
      fichiers sont compilés en fichiers objets
      correspondants (.o), puis un objet dynamiquement partagé
      fichier-dso est compilé via une édition de liens de ces
      fichiers objets avec les autres fichiers objets (.o and .a)
      spécifiés par fichiers. Si l'option -o
      n'est pas spécifiée, le nom du fichier résultant est déduit du
      premier nom de fichier spécifié par fichiers, et ainsi
      prend en général pour valeur par défaut
      mod_nom.so.
    

      
    -o fichier-dso
    
      
    Spécifie de manière explicite le nom de fichier de l'objet
      partagé dynamiquement créé. Sans cette option, et si le nom ne
      peut pas être déduit de la liste fichiers, c'est le nom
      par défaut mod_unknown.so qui sera utilisé.
    

      
    -D nom=valeur
    
      
    Cette option est transmise directement à la commande de
      compilation. Vous pouvez l'utiliser pour ajouter vos propres
      définitions au processus de compilation. 
    

      
    -I répertoire-inc
    
      
    Cette option est transmise directement à la commande de
      compilation. Vous pouvez l'utiliser pour ajouter vos propres
      chemins de recherche des répertoires include au processus de
      compilation.
    

      
    -L répertoire-lib
    
      
    Cette option est transmise directement à la commande d'édition
      de liens. Vous pouvez l'utiliser pour ajouter vos propres
      chemins de recherche des répertoires de bibliothèques au processus
      de compilation.
    

      
    -l nom-bibliothèque
    
      
    Cette option est transmise directement à la commande d'édition
      de liens. Vous pouvez l'utiliser pour ajouter vos propres
      bibliothèques à rechercher au processus de compilation.
    

      
    -Wc,options-compilation
    
      
    Cette option transmet les options-compilation en
      tant qu'options supplémentaires à la commande libtool
      --mode=compile. Vous pouvez l'utiliser pour ajouter des
      options locales spécifiques au compilateur.
    

      
    -Wl,options-edition-liens
    
      
    Cette option transmet les options-edition-liens en
      tant qu'options supplémentaires à la commande libtool
      --mode=link. Vous pouvez l'utiliser pour ajouter des
      options locales spécifiques à l'éditeur de liens.
    
      
      
    -p
    
      
    Avec cette option, apxs effectue l'édition de liens avec les
      bibliothèques apr/apr-util. Elle permet de compiler les programmes
      helper qui utilisent les bibliothèques apr/apr-util.
    
      
    
    

    
    Options d'installation et de configuration DSO
    
    
      
    
      
    -i
    
      
    Cette option indique une opération d'installation et installe
      un ou plusieurs objets dynamiquement partagés dans le répertoire
      modules du serveur.
    

      
    -a
    
      
    Cette option active le module en ajoutant automatiquement une
      directive LoadModule
      correspondante au fichier de configuration d'Apache
      httpd.conf, ou en l'activant s'il existe déjà.
    

      
    -A
    
      
    Identique à l'option -a, à la différence que la
      directive LoadModule créée
      est préfixée par un caractère dièse (#) ; le module
      est ainsi préparé pour une activation ultérieure, mais est
      désactivé dans un premier temps.
    

      
    -e
    
      
    Cette option indique une opération d'édition de liens et peut
      être utilisée avec les options -a et -A
      de la même manière qu'au cours de l'opération d'installation pour
      éditer le fichier de configuration d'Apache
      httpd.conf, sans toutefois installer le module.
    
      
    
    

    top
    

    

    Exemples
    
    
    Supposons que vous disposiez d'un module Apache nommé
    mod_foo.c et destiné à étendre les fonctionnalités du
    serveur. Pour ce faire, vous devez tout d'abord compiler le fichier
    source C en un objet partagé pouvant être chargé dans le serveur
    Apache à l'exécution, via la commande suivante :
    

    
    
      $ apxs -c mod_foo.c
    
      /chemin/vers/libtool --mode=compile gcc ... -c mod_foo.c
    
      /chemin/vers/libtool --mode=link gcc ... -o mod_foo.la mod_foo.slo
    
      $ _
    
    

    
    Vous devez ensuite vérifier la configuration d'Apache en vous
    assurant qu'une directive LoadModule est bien présente pour
    charger cet objet partagé. Pour simplifier cette étape,
    apxs propose une méthode automatique d'installation de
    l'objet partagé dans son répertoire "modules", et de mise à jour du
    fichier httpd.conf en conséquence. Pour bénéficier de
    cette automatisation, utilisez la commande suivante :
    

    
    
      $ apxs -i -a mod_foo.la
    
      /chemin/vers/instdso.sh mod_foo.la /chemin/vers/apache/modules
    
      /chemin/vers/libtool --mode=install cp mod_foo.la /chemin/vers/apache/modules
      ...
      chmod 755 /chemin/vers/apache/modules/mod_foo.so
    
      [activation du module `foo' dans /chemin/vers/apache/conf/httpd.conf]
    
      $ _
    
    

    
    Une ligne contenant
    

    
    
      LoadModule foo_module modules/mod_foo.so
    
    

    
    est alors ajoutée au fichier de configuration si ce n'est pas
    déjà fait. Si vous voulez que le module soit désactivé par défaut,
    utilisez l'option -A comme suit :
    

    
    
      $ apxs -i -A mod_foo.c
    
    

    
    Pour un test rapide du mécanisme apxs, vous pouvez créer un
    exemple de modèle de module Apache, ainsi que le Makefile
    correspondant via :
    

    
    
      $ apxs -g -n foo
    
      Creating [DIR]  foo
    
      Creating [FILE] foo/Makefile
    
      Creating [FILE] foo/modules.mk
    
      Creating [FILE] foo/mod_foo.c
    
      Creating [FILE] foo/.deps
    
      $ _
    
    

    
    Vous pouvez ensuite compiler immédiatement ce module exemple en
    objet partagé et le charger dans le serveur Apache :
    

    
    
      $ cd foo
    
      $ make all reload
    
      apxs -c mod_foo.c
    
      /chemin/vers/libtool --mode=compile gcc ... -c mod_foo.c
    
      /chemin/vers/libtool --mode=link gcc ... -o mod_foo.la mod_foo.slo
    
      apxs -i -a -n "foo" mod_foo.la
    
      /chemin/vers/instdso.sh mod_foo.la /chemin/vers/apache/modules
    
      /chemin/vers/libtool --mode=install cp mod_foo.la /chemin/vers/apache/modules
      ...
      chmod 755 /chemin/vers/apache/modules/mod_foo.so
    
      [activation du module `foo' dans /chemin/vers/apache/conf/httpd.conf]

    htdigest is used to create and update the flat-files used
    to store usernames, realm and password for digest authentication of HTTP
    users. Resources available from the Apache HTTP server can be restricted
    to just the users listed in the files created by htdigest.
    

    
    This manual page only lists the command line arguments. For details of
    the directives necessary to configure digest authentication in
    httpd see the Apache manual, which is part
    of the Apache distribution or can be found at
    http://httpd.apache.org/.

    username
    
    
    The user name to create or update in passwdfile. If
    username does not exist is this file, an entry is added. If it
    does exist, the password is changed.

    sadece, kullanıcı isimleri bir DBM dosyasında saklanmak istenirse işe
    yarar. Düz metin bir veritabanı kullanmak isterseniz
    htpasswd sayfasına bakınız.
    

    
    DBM parola veritabanı sağlayan diğer bir araç da
      htdbm'dir.

    Hatalar
    
    
    Birden fazla DBM dosya biçemi vardır ve büyük bir olasılıkla da
    sisteminizde bu birden fazla biçemle ilgili kütüphaneler vardır. SDBM,
    NDBM, GNU'nun GDBM projesi ve Berkeley DB 2 bunların başlıcalarıdır. Ne
    yazık ki, bu kütüphanelerin her birinin dosya biçimleri farklıdır. Bu
    bakımdan, dosyaismi dosyasında kullanılan dosya
    biçeminin dbmmanage tarafından kullanılanla
    aynı biçemde olduğundan emin olmalısınız.
    dbmmanage hangi tür DBM dosyasına baktığını
    saptayacak yeterliliğe sahip değildir. Yanlış biçemli bir dosya
    belirtirseniz hiçbir şey dönmeyebileceği gibi, başka isimde bir DBM
    dosyasının oluşturulması veya daha da kötüsü üzerine yazmaya
    çalışıyorsanız DBM dosyasının bozulması bile olasıdır.
    

    
    dbmmanage programının başlangıcında
    @AnyDBM::ISA dizisi olarak tanımlanmış DBM biçem
    tercihlerinin bir listesi vardır. Berkeley DB 2 biçemini tercih
    ettiğimizden dbmmanage sistem
    kütüphanelerini şu sıraya göre arar: Berkeley DB 2, NDBM, GDBM ve SDBM.
    dbmmanage DBM dosyası hareketleri için  bu
    sıralamaya göre bulduğu ilk kütüphaneyi kullanacaktır. Sıralama Perl'deki
    dbmopen() çağrısının kullandığından faklı olduğu gibi
    Perl'deki standart @AnyDBM::ISA sıralamasından da oldukça
    farklıdır. Bu bakımdan, DBM dosyalarınızı yönetmek için Perl ile yazılmış
    başka araçlar kullanıyorsanız, onların da bu tercih sırasını izlemesini
    sağlamalısınız. Benzer şekilde, bu dosyalara erişmek için diğer dillerde
    (C gibi) yazılmış programlar kullanıyorsanız bunlar için de aynı durum
    geçerlidir.
    

    
    Unix sistemlerinde, kullanılan DBM dosyasının biçemini öğrenmek için
    file programı kullanılabilir.

    htpasswd, HTTP kullanıcılarının temel
    kimlik doğrulaması için kullanıcı isimlerinin ve parolalarının
    saklanmasında kullanılacak düz metin dosyalarını oluşturmak ve güncellemek
    için kullanılır. htpasswd, güncelleme
    sırasında yazmak veya okumak için bir dosyaya erişemezse beklenen hiçbir
    işlemi yapmaz ve hata vererek çıkar.
    

    
    Apache HTTP sunucusunun mevcut özkaynaklarının kullanımı
    sadece htpasswd tarafından oluşturulan
    dosyalarda listelenmiş kullanıcılara tahsis edilebilir.
    htpasswd sadece düz metin dosyalarda
    saklanmış kullanıcı isimlerini ve parolalarını yönetirse de, diğer veri
    saklama türleri için parolayı şifreleyip gösterebilir. Bir DBM veritabanı
    kullanmak isterseniz dbmmanage ve
    htdbm sayfasına bakınız.
    

    
    htpasswd, parolaları şifrelemek için
    bcrypt, Apache'nin kendine özgü MD5 algoritması, SHA1 ya da sistemin
    crypt() yordamını kullanır. Bu bakımdan
    htpasswd tarafından yönetilen dosyalar farklı
    algoritmalarla şifrelenmiş parolalar içerebilir.

    Seçenekler
    
    
    
    
    -b
    
    
    Betik kipi; parola için istek yapmak yerine parola komut satırından
    verilir. Parola komut satırında görünür olacağından çok
    dikkatli kullanmak gerekir. Betik kullanımı için
    -i seçeneğine bakınız.
    2.4.4 ve sonraki sürümler içindir.
    

    
    -i
    
    
    Parolayı doğrulamaksızın standart girdiden okur (betik kullanımı
    için).
    

    
    -c
    
    
    parola-dosyası oluşturur. Dosya mevcutsa,
    dosya silinip yeniden yazılır. Bu seçenek
    -n seçeneği ile birlikte kullanılamaz.
    

    
    -n
    
    
    Sonuçları veritabanında güncellemek yerine standart çıktıya gönderir.
    Bu seçenek, Apache'nin metin veriler içermeyen veri depolarına dahil
    edilebilecek parolaları üretmekte yararlıdır.
    parola-dosyası belirtilmediğinden, bu seçenek
    komut satırı sözdizimini değiştirir. Bu seçenek
    -c seçeneği ile birlikte kullanılamaz.
    

    
    -m
    
    
    Parolalar için MD5 şifrelemesi kullanılır.
    Bu 2.2.18 sürümünden beri öntanımlıdır.
    

    
    -B
    
    
    Parolalar için bcrypt şifrelemesi kullanılır. Şu an için çok güvenli
    kabul edilmektedir.
    

    
    -C  bedel
    
    
    Bu seçenek sadece -B (bcrypt şifrelemesi)
    seçeneği ile birlikte kullanılabilir. Bcrypt algoritmasına hesaplama
    süresini belirtir (daha yüksek değerler daha güvenlidir, öntanımlı 5,
    geçerli değerler: 4 - 17).
    

    
    -d
    
    
    Parolaları şifrelemek için crypt() kullanılır.
    htpasswd tarafından tüm platformlarda
    destekleniyor olsa da Windows, Netware ve TPF üzerinde
    httpd sunucusu tarafından desteklenmez. Bu algoritma
    günümüz standartlarında güvenilmez kabul
    edilmektedir. 2.2.17 sürümüne kadar öntanımlı algoritma olarak
    kullanılmıştı.
    

    
    -s
    
    
    Parolalar için SHA şifrelemesi kullanılır. LDAP Dizin değişim
    biçemini (ldif) kullanarak Netscape sunucularına/sunucularından göçü
    kolaylaştırır.Bu algoritma günümüz standartlarında
    güvenilmez kabul edilmektedir.
    

    
    -p
    
    
    Düz metin parolalar kullanılır. htpasswd
    tarafından tüm platformlarda destekleniyor olsa da Windows, Netware ve
    TPF üzerinde httpd sunucusu tarafından sadece düz
    metin parolalar kabul edilir.
    

    
    -D
    
    
    Kullanıcıyı siler. Kullanıcı belirtilen dosyada mevcutsa
    silinir.
    

    
    -v
    
    
    Parolayı doğrular. Verilen parolayı belitilen htpasswd dosyasında
      saklanan kullanıcı parolası ile karşılaştırarak doğrulama yapar.
      2.4.5 ve sonraki sürümler içindir.
    

    
    parola-dosyası
    
    
    Kullanıcı ismini ve parolasını içeren dosyanın ismi.
    -c seçeneği verilmişse ve dosya mevcut
    değilse oluşturulur, dosya mevcutsa silinip yeniden oluşturulur.
    

    
    kullanıcı
    
    
    parola-dosyası'nda oluşturulacak veya
    güncellenecek kullanıcı ismi. kullanıcı bu
    dosyada mevcut değilse yeni bir girdi eklenir. Girdi mevcutsa parolası
    değiştirilir.
    

    
    parola
    
    
    Şifrelenip dosyada saklanacak düz metin parola. Sadece
    -b seçeneği ile kullanılır.

    Örnekler
    
    
    
      htpasswd /usr/local/etc/apache/.htpasswd-users jsmith
    
    

    
    jsmith kullanıcısı için parolayı ekler veya değiştirir.
    Parolayı vermesi için kullanıcıya parola isteği yapılır.
    Parola takviyeli Apache MD5 algoritması ile şifrelenir. Dosya mevcut
    değilse htpasswd beklenen hiçbir işlemi
    yapmadan bir hata vererek çıkar.
    

    
    
      htpasswd -c /home/doe/public_html/.htpasswd jane
    
    

    
    Yeni bir dosya oluşturur ve kullanıcı jane için kaydı bir
    girdi olarak bu dosyaya yazar. Dosya mevcutsa fakat okunamıyor veya
    yazılamıyorsa dosyada bir değişiklik yapılmaz ve
    htpasswd bir ileti gösterip bir hata durumu
    ile çıkar.
    

    
    
      htpasswd -db /usr/web/.htpasswd-all jones Pwd4Steve
    
    

    
    Komut satırından verilen parolayı (Pwd4Steve) crypt()
    algoritmasıyla şifreler ve bunu belirtilen dosyada saklar.
    

    top
    

    

    Güvenlik Değerlendirmeleri
    
    
    htpasswd tarafından yönetilen parola
    dosyalarına sunucunun URI uzayından erişilememelidir; yani dosya bir
    tarayıcı ile okunabilecek bir yerde bulunmamalıdır.
    

    
    Bu program bir setuid çalıştırılabiliri olarak güvenilir olmadığından
    setuid yapılmamalıdır.
    

    
    Komut satırında parolanın şifrelenmemiş olarak görünmesi sebebiyle
    -b seçeneğinin kullanımından kaçınılmasını
    öneriyoruz.
    

    
    crypt() algoritması kullanılırken, parolayı
    şekillendirmek için parolanın ilk 8 baytının kullanılacağına dikkat
    ediniz. Eğer parola 8 bayttan uzunsa kalanlar bir uyarı verilmeksizin
    iptal edilir.
    

    
    SHA şifreleme biçeminde tuz kullanılmaz; yani, bir parolanın
    sadece bir şifreli gösterimi olabilir. crypt() ve
    MD5 biçemleri parolanın önüne rasgele üretilmiş bir tuz dizgesi
    eklediklerinden sözlük saldırılarına karşı daha dayanıklıdırlar.
    

    
    SHA ve crypt() biçimleri günümüz standartlarında
    güvenilmez kabul edilmektedir.
    

    top
    

    

    Kısıtlamalar
    
    
    Windows platformuda, htpasswd
    ile şifrelenen parolalar 255 karakterden daha uzun olamaz.
    255 karakterden sonrası kırpılır.
    

    
    htpasswd tarafından kullanılan MD5
    algoritması Apache yazılımına özeldir; bu algoritma ile şifrelenen
    parolalar başka HTTP sunucularında kullanılamayabilir.
    

    
    Kullanıcı isimleri 255 bayttan uzun olamaz ve iki nokta
    imi (:) içeremez.
    
    
    
    Bir bcrypt parolasının karma değerini hesaplamanın maliyeti, 
    -C seçeneğinde belirtilen tur sayısı ile artar.
    apr-util kitaplığının 1.6.0 ve sonraki 
    sürümleri için azami tur sayısı 17 ile sınırlıdır.

    htpasswd - Manage user files for basic authentication

    htpasswd is used to create and update the flat-files used to
    store usernames and password for basic authentication of HTTP users. If
    htpasswd cannot access a file, such as not being able to write
    to the output file or not being able to read the file in order to update it,
    it returns an error status and makes no changes.
    

    
    Resources available from the Apache HTTP server can be restricted to
    just the users listed in the files created by htpasswd. This
    program can only manage usernames and passwords stored in a flat-file. It
    can encrypt and display password information for use in other types of data
    stores, though. To use a DBM database see dbmmanage or
    htdbm.
    

    
    htpasswd encrypts passwords using either bcrypt,
    a version of MD5 modified for Apache, SHA1, or the system's
    crypt() routine. Files
    managed by htpasswd may contain a mixture of different encoding
    types of passwords; some
    user records may have bcrypt or MD5-encrypted passwords while others in the
    same file may have passwords encrypted with crypt().
    

    
    This manual page only lists the command line arguments. For details of
    the directives necessary to configure user authentication in
    httpd see the Apache manual, which is part of the
    Apache distribution or can be found at http://httpd.apache.org/.

    Options
    
    
    
    
    -b
    
    
    Use batch mode; i.e., get the password from the command line
    rather than prompting for it. This option should be used with extreme care,
    since the password is clearly visible on the command
    line. For script use see the -i option.
    Available in 2.4.4 and later.
    

    
    -i
    
    
    Read the password from stdin without verification (for script usage).
    

    
    -c
    
    
    Create the passwdfile. If passwdfile already
    exists, it is rewritten and truncated. This option cannot be combined with
    the -n option.
    

    
    -n
    
    
    Display the results on standard output rather than updating a file.
    This is useful for generating password records acceptable to Apache for
    inclusion in non-text data stores. This option changes the syntax of the
    command line, since the passwdfile argument (usually the first
    one) is omitted. It cannot be combined with the -c option.
    

    
    -m
    
    
    Use MD5 encryption for passwords. This is the default (since version
    2.2.18).
    

    
    -B
    
    
    Use bcrypt encryption for passwords. This is currently considered to
    be very secure.
    

    
    -C
    
    
    This flag is only allowed in combination with -B (bcrypt
    encryption). It sets the computing time used for the bcrypt algorithm
    (higher is more secure but slower, default: 5, valid: 4 to 17).
    

    
    -d
    
    
    Use crypt() encryption for passwords. This is not
    supported by the httpd server on Windows and
    Netware. This algorithm limits the password length to 8 characters.
    This algorithm is insecure by today's standards.
    It used to be the default algorithm until version 2.2.17.
    

    
    -s
    
    
    Use SHA encryption for passwords. Facilitates migration from/to Netscape
    servers using the LDAP Directory Interchange Format (ldif).
    This algorithm is insecure by today's standards.
    

    
    -p
    
    
    Use plaintext passwords. Though htpasswd will support
    creation on all platforms, the httpd daemon will
    only accept plain text passwords on Windows and Netware.
    

    
    -D
    
    
    Delete user. If the username exists in the specified htpasswd file, it
    will be deleted.
    

    
    -v
    
    
    Verify password. Verify that the given password matches the password
    of the user stored in the specified htpasswd file.
    Available in 2.4.5 and later.
    

    
    passwdfile
    
    
    Name of the file to contain the user name and password. If
    -c is given, this file is created if it does not already exist,
    or rewritten and truncated if it does exist.
    

    
    username
    
    
    The username to create or update in passwdfile. If
    username does not exist in this file, an entry is added. If it
    does exist, the password is changed.
    

    
    password
    
    
    The plaintext password to be encrypted and stored  in the file. Only
    used with the -b flag.
    
    
    

    top
    

    

    Exit Status
    
    
    htpasswd returns a zero status ("true") if the username and
    password have been successfully added or updated in the
    passwdfile. htpasswd returns 1 if it
    encounters some problem accessing files, 2 if there was a
    syntax problem with the command line, 3 if the password was
    entered interactively and the verification entry didn't match,
    4 if its operation was interrupted, 5 if a value
    is too long (username, filename, password, or final computed record),
    6 if the username contains illegal characters (see the
    Restrictions section), and 7
    if the file is not a valid password file.
    

    top
    

    

    Examples
    
    
    
      htpasswd /usr/local/etc/apache/.htpasswd-users jsmith
    
    

    
    Adds or modifies the password for user jsmith. The user
    is prompted for the password. The password will be encrypted using the
    modified Apache MD5 algorithm. If the file does not exist,
    htpasswd will do nothing except return an error.
    

    
    
      htpasswd -c /home/doe/public_html/.htpasswd jane
    
    

    
    Creates a new file and stores a record in it for user jane.
    The user is prompted for the password. If the file exists and cannot be
    read, or cannot be written, it is not altered and htpasswd
    will display a message and return an error status.
    

    
    
      htpasswd -db /usr/web/.htpasswd-all jones Pwd4Steve
    
    

    
    Encrypts the password from the command line (Pwd4Steve)
    using the crypt() algorithm, and stores it in the specified
    file.
    

    top
    

    

    Security Considerations
    
    
    Web password files such as those managed by htpasswd should
    not be within the Web server's URI space -- that is, they should
    not be fetchable with a browser.
    

    
    This program is not safe as a setuid executable. Do not make it
    setuid.
    

    
    The use of the -b option is discouraged, since when it is
    used the unencrypted password appears on the command line.
    

    
    When using the crypt() algorithm, note that only the first
    8 characters of the password are used  to form the password. If the supplied
    password is longer, the extra characters will be silently discarded.
    

    
    The SHA encryption format does not use salting: for a given password,
    there is only one encrypted representation. The crypt() and
    MD5 formats permute the representation by prepending a random salt string,
    to make dictionary attacks against the passwords more difficult.
    

    
    The SHA and crypt() formats are insecure by today's
    standards.
    

    top
    

    

    Restrictions
    
    
    On the Windows platform, passwords encrypted with
    htpasswd are limited to no more than 255
    characters in length. Longer passwords will be truncated to 255
    characters.
    

    
    The MD5 algorithm used by htpasswd is specific to the Apache
    software; passwords encrypted using it will not be usable with other Web
    servers.
    

    
    Usernames are limited to 255 bytes and may not include the
    character :.
    

    
    The cost of computing a bcrypt password hash value increases
    with the number of rounds specified by the -C option.
    The apr-util library enforces a maximum number of
    rounds of 17 in version 1.6.0 and later.

    httpd est le programme du serveur HTTP d'Apache. Il
     a été conçu pour fonctionner sous forme de processus démon
     indépendant. Lorsqu'il est utilisé ainsi, il va créer un jeu de
     processus enfants ou de threads qui traiteront les requêtes.
    

     
    En général, httpd n'est pas invoqué directement,
     mais plutôt via apachectl sur les systèmes de
     style Unix ou en tant que service sous
     Windows NT, 2000 et XP et comme application de
     console sous Windows 9x et ME.

    rotatelogs is a simple program for use in
     conjunction with Apache's piped logfile feature.  It supports
     rotation based on a time interval or maximum size of the log.

    top
    

    

    Options
    


    


    -l
    

    Causes the use of local time rather than GMT as the base for the
interval or for strftime(3) formatting with size-based
rotation.
    


    -L linkname
    

    Causes a hard link to be made from the current logfile
to the specified link name.  This can be used to watch
the log continuously across rotations using a command like
tail -F linkname.
    

    If the linkname is not an absolute
path, it is relative to rotatelogs' working directory,
which is the ServerRoot when
rotatelogs is run by the server.  

    

    


    -p program
    


    If given, rotatelogs will execute the specified
program every time a new log file is opened.  The filename of the
newly opened file is passed as the first argument to the program.  If
executing after a rotation, the old log file is passed as the second
argument.  rotatelogs does not wait for the specified
program to terminate before continuing to operate, and will not log
any error code returned on termination.  The spawned program uses the
same stdin, stdout, and stderr as rotatelogs itself, and also inherits
the environment.
    


    -f
    

    Causes the logfile to be opened immediately, as soon as
rotatelogs starts, instead of waiting for the
first logfile entry to be read (for non-busy sites, there may be
a substantial delay between when the server is started
and when the first request is handled, meaning that the
associated logfile does not "exist" until then, which
causes problems from some automated logging tools)
    


    -D
    

    Creates the parent directories of the path that the log file will be
placed in if they do not already exist.  This allows strftime(3)
formatting to be used in the path and not just the filename.
    


    -t
    

    Causes the logfile to be truncated instead of rotated. This is
useful when a log is processed in real time by a command like tail,
and there is no need for archived data. No suffix will be added to
the filename, however format strings containing '%' characters
will be respected.

    


    -v
    

    Produce verbose output on STDERR. The output contains
the result of the configuration parsing, and all file open and
close actions.
    


    -e
    

    Echo logs through to stdout. Useful when logs need to be further
processed in real time by a further tool in the chain.
    


    -c
    

    Create log file for each interval, even if empty.
    


    -n number-of-files
    

    Use a circular list of filenames without timestamps.
With -n 3, the series of log files opened would be
"logfile", "logfile.1", "logfile.2", then overwriting "logfile".
Available in 2.4.5 and later.
    


    logfile
    


    The path plus basename of the logfile.  If logfile
includes any '%' characters, it is treated as a format string for
strftime(3).  Otherwise, the suffix
.nnnnnnnnnn is automatically added and is the time in
seconds (unless the -t option is used). Both formats compute the
start time from the beginning of the current period.  For example,
if a rotation time of 86400 is specified, the hour, minute, and
second fields created from the strftime(3) format will
all be zero, referring to the beginning of the current 24-hour
period (midnight).
    

    When using strftime(3) filename formatting,
be sure the log file format has enough granularity to produce
a different file name each time the logs are rotated.  Otherwise
rotation will overwrite the same file instead of starting a new
one.  For example, if logfile was
/var/log/errorlog.%Y-%m-%d with log rotation at 5
megabytes, but 5 megabytes was reached twice in the same day, the
same log file name would be produced and log rotation would keep
writing to the same file.
    

    If the logfile is not an absolute
path, it is relative to rotatelogs' working directory,
which is the ServerRoot when
rotatelogs is run by the server.

    

    


    rotationtime
    


    The time between log file rotations in seconds.  The rotation
occurs at the beginning of this interval.  For example, if the
rotation time is 3600, the log file will be rotated at the beginning
of every hour; if the rotation time is 86400, the log file will be
rotated every night at midnight.  (If no data is logged during an
interval, no file will be created.)
    


    filesize(B|K|M|G)
    


    The maximum file size in followed by exactly one of the letters
B (Bytes), K (KBytes), M (MBytes)
or G (GBytes).

    
When time and size are specified, the size must be given after the time.
Rotation will occur whenever either time or size limits are reached.

    

    


    offset
    


    The number of minutes offset from UTC.  If omitted, zero is
assumed and UTC is used.  For example, to use local time in the zone
UTC -5 hours, specify a value of -300 for this argument.
In most cases, -l should be used instead of specifying
an offset.
    


    

    top
    

    

    Examples
    


    
     CustomLog "|bin/rotatelogs /var/log/logfile 86400" common

    

     
    This creates the files /var/log/logfile.nnnn where nnnn  is
     the system time at which the log nominally starts (this time
     will always be a multiple of the rotation time, so  you  can
     synchronize cron scripts with it).  At the end of each rotation
     time (here after 24 hours) a new log is started.
    


    
     CustomLog "|bin/rotatelogs -l /var/log/logfile.%Y.%m.%d 86400" common

    

     
    This creates the files /var/log/logfile.yyyy.mm.dd where
     yyyy is the year, mm is the month, and dd is the day of the month.
     Logging will switch to a new file every day at midnight, local time.
    


    
     CustomLog "|bin/rotatelogs /var/log/logfile 5M" common

    

     
    This configuration will rotate the logfile whenever it reaches
     a size of 5 megabytes.
    


    
     ErrorLog "|bin/rotatelogs /var/log/errorlog.%Y-%m-%d-%H_%M_%S 5M"

    
     
    This configuration will rotate the error logfile whenever it
     reaches a size of 5 megabytes, and the suffix to the logfile name
     will be created of the form
     errorlog.YYYY-mm-dd-HH_MM_SS.
    


    
     CustomLog "|bin/rotatelogs -t /var/log/logfile 86400" common

    

     
    This creates the file /var/log/logfile, truncating the file at
     startup and then truncating the file once per day. It is expected
     in this scenario that a separate process (such as tail) would
     process the file in real time.

    Portability
    


    The following logfile format string substitutions should be
supported by all strftime(3) implementations, see

    httpd is the Apache HyperText Transfer Protocol
     (HTTP) server program.  It is designed to be run as a standalone
     daemon process. When used like this it will create a pool of
     child processes or threads to handle requests.
    

     
    In general, httpd should not be invoked directly,
     but rather should be invoked via apachectl on Unix-based systems or as a service on Windows NT,
     2000 and XP and as
     a console application on Windows 9x and ME.

    Options
    


    

    -d serverroot
    


    Set the initial value for the ServerRoot directive to
serverroot.  This can be overridden by the ServerRoot
directive in the configuration file. The default is
/usr/local/apache2.
    


    -f config
    


    Uses the directives in the file config on startup. If
config does not begin with a /, then it is taken to be a
path relative to the ServerRoot. The default is
conf/httpd.conf.
    


    -k start|restart|graceful|stop|graceful-stop
    


    Signals httpd to start, restart, or stop.  See Stopping Apache httpd for more information.
    


    -C directive
    


    Process the configuration directive before reading
config files.
    


    -c directive
    


    Process the configuration directive after reading config
files.
    



    -D parameter
    


    Sets a configuration parameter which can be used with
<IfDefine> sections
in the configuration files to conditionally skip or process commands
at server startup and restart. Also can be used to set certain
less-common startup parameters including -DNO_DETACH
(prevent the parent from forking) and -DFOREGROUND
(prevent the parent from calling setsid() et al).
    


    -e level
    


    Sets the LogLevel to
level during server startup.  This is useful for
temporarily increasing the verbosity of the error messages to find
problems during startup.
    


    -E file
    


    Send error messages during server startup to file.
    


    -h
    


    Output a short summary of available command line options.
    


    -l
    


    Output a list of modules compiled into the server.  This will
not list dynamically loaded modules included using
the LoadModule directive.
    


    -L
    


    Output a list of directives provided by static modules, together with expected arguments and
places where the directive is valid. Directives provided by shared modules are not listed.
    


    -M
    


    Dump a list of loaded Static and Shared Modules.
    


    -S
    


    Show the settings as parsed from the config file (currently only
shows the virtualhost settings).
    


    -T (Available in 2.3.8 and later)
    


    Skip document root check at startup/restart.
    


    -t
    


    Run syntax tests for configuration files only.  The program
immediately exits after these syntax parsing tests with either a return code
of 0 (Syntax OK) or return code not equal to 0 (Syntax Error).  If -D
DUMP_VHOSTS is also set, details of the virtual host
configuration will be printed. If -D DUMP_MODULES  is
set, all loaded modules will be printed.
    


    -v
    


    Print the version of httpd, and then exit.
    


    -V
    


    Print the version and build parameters of httpd, and
then exit.
    


    -X
    


    Run httpd in debug mode.  Only one worker will be started and the
server will not detach from the console.
    


    


    The following arguments are available only on the Windows platform:
    


    


    -k install|config|uninstall
    


    Install Apache httpd as a Windows NT service; change startup options for
the Apache httpd service; and uninstall the Apache httpd service.
    


    -n name
    


    The name of the Apache httpd service to signal.
    


    -w

    apachectl Apache Hiper Metin Aktarım
      Protokolü (HTTP) sunucusu için bir denetim aracıdır. Sistem
      yöneticisinin Apache httpd artalan
      sürecini denetimi altında tutabilmesine yardımcı olmak amacıyla
      tasarlanmıştır.
    

    
    apachectl iki kipte işleyebilir.
      İlkinde, httpd komutu için basit
      bir önyüz gibi davranarak, gerekli ortam değişkenlerini atar ve
      belirtilen komut satırı seçenekleriyle
      httpd sürecini başlatır. İkinci
      kipte ise, apachectl bir SysV başlatma
      betiği olarak start,
      restart,
      stop gibi tek sözcüklük basit argümanlar
      alır ve bunları uygun sinyallere dönüştürerek
      httpd'ye gönderir.
    

    
    Eğer Apache kurulumunuzda standart dışı dosya yolları kullanmışsanız,
      httpd programına uygun yolları
      atamak için apachectl betiğini elden
      geçirmelisiniz. Bu arada gerek gördüğünüz
      httpd komut satırı argümanlarını da
      belirtebilirsiniz. Ayrıntılar için betik içindeki açıklamalara
      bakınız.
    

    
    apachectl betiği başarı durumunda 0
      çıkış değeri ile döner. Bir hata durumunda ise sıfırdan farklı bir
      değerle döner. Daha fazla bilgi için betik içindeki açıklamalara
      bakınız.

    Seçenekler
    

    
    Burada sadece SysV başlatma betiğine özgü seçeneklere yer verilmiştir.
      Diğer argümanlar için httpd kılavuz
      sayfasına bakınız.
    

    
    
      
    start
    
      
    Apache httpd artalan sürecini
        başlatır. Zaten çalışmaktaysa bir hata verir. apachectl
        -k start komutuna eşdeğerdir.
    

      
    stop
    
      
    Apache httpd artalan sürecini
        durdurur. apachectl -k stop komutuna
        eşdeğerdir.
    

      
    restart
    
      
    Apache httpd artalan sürecini
        yeniden başlatır; çalışmıyorsa çalıştırılır. Artalan sürecinin ölü
        olmadığından emin olmak için yeniden başlatmadan önce
        configtest seçeneği verilmiş gibi
        yapılandırma dosyaları sınanır. apachectl -k
        restart komutuna eşdeğerdir.
    

      
    fullstatus
    
      
    mod_status üzerinden tam bir
        durum raporu gösterir. Bunun çalışması için sunucuda
        mod_status etkinleştirilmiş olmalı
        ve sisteminizde lynx gibi bir metin
        kipi HTTP tarayıcı kurulu olmalıdır. Durum raporuna erişmek için
        kullanılacak adres betik içinde STATUSURL değişkenine
        atanabilir.
    

      
    status
    
      
    Özet halinde bir durum raporu gösterir. O an sunulmakta olan
        isteklerin gösterilmemesi dışında
        fullstatus seçeneği gibidir.
    

      
    graceful
    
      
    Apache httpd artalan sürecini
        nazikçe yeniden başlatır; çalışmıyorsa çalıştırılır. O an
        hizmet sunmakta olan çocuk süreçleri hemen durdurmaması dışında
        normal yeniden başlatma gibidir. Bir yan etki olarak eski günlük
        dosyaları hemen kapatılmaz. Yani, günlük dosyalarını döndüren bir
        betik kullanıyorsanız yenilerini başlatmadan önce eski dosyaların
        tamamen kapandığından emin olmak için belli bir süre beklemeniz
        gerekecektir. Artalan sürecinin ölü olmadığından emin olmak için
        yeniden başlatmadan önce  configtest
        seçeneği verilmiş gibi yapılandırma dosyaları sınanır.
        apachectl -k graceful komutuna
        eşdeğerdir.
    

      
    graceful-stop
    
      
    Apache httpd artalan sürecini
        nazikçe durdurur. O an hizmet sunmakta olan çocuk süreçleri
        hemen durdurmaması dışında normal durdurma gibidir. Bir yan etki
        olarak eski günlük dosyaları hemen kapatılmaz.
        apachectl -k graceful-stop komutuna
        eşdeğerdir.
    

      
    configtest
    
      
    Yapılandırma dosyasında sözdizimi denetimi yapılmasını sağlar.
        Yapılandırma dosyaları çözümlenir ve bir sorun yoksa bir Syntax
        Ok raporu verilir fakat, bir hata varsa o hataya ilişkin
        ayrıntılı bilgi verilir. apachectl -t
        komutuna eşdeğerdir.
    

    
    

    
    Aşağıdaki seçenek eski sürümlerde kullanılmaktaydı, fakat artık
      kullanılmamaktadır.
    

    
    
      
    startssl
    
      
    httpd programını SSL destekli
        başlatmak için, yapılandırma dosyanızı ilgili yönergeleri içermesi
        için elden geçirmeli ve normal apachectl
        start komutunu kullanmalısınız.

    logresolve, Apache'nin erişim
     günlüklerindeki IP adreslerini çözümlemek için bir ardıl işlem
     uygulamasıdır. İsim sunucunuza bindirdiği yükü en aza indirmek için
     logresolve kendi arabelleğinde oluşturduğu
     eşleme tablosunu kullanır.
    

     
    Apache günlük dosyasını standart girdisinden okur. IP adresleri günlük
     dosyası satırlarında ilk bileşen olmalı ve sonraki bileşenlerden bir
     boşluk ile ayrılmalıdır.

    -s dosyaismi
    
    
    İstatistiklerin kaydedileceği dosyanın ismi belirtilir.
    

    
    -c
    
    
    logresolve uygulamasının bazı DNS
    sorguları yapmasına sebep olur: IP adresine karşılık olan konak ismini
    bulduktan sonra özgün adresle karşılaştırmak için bu konak ismine karşılık
    gelen IP adresini sorgular.

    Börtü böcek
    
    
    Duruk bildirimli sabit uzunlukta çeşitli tamponlar vardır.
      Sunucudan gelen yanıt başlıkları ve diğer harici girdiler, komut satırı
      argümanları ile birlikte basitçe çözümlenir, bu size can sıkıcı
      gelebilir.
    

    
    HTTP/1.x protokolünü tamamen gerçeklemez; sadece yanıtların 'belli
      başlı' bazı biçimlerini kabul eder. Aksi takdirde,
      strstr(3) işlevinin yoğun kullanımı
      nedeniyle sunucu yerine ab'nin başarımını
      ölçerdiniz.

    rotatelogs, Apache'nin borulu günlük
     dosyaları özelliği ile birlikte kullanmak için tasarlanmış basit bir
     programdır. Günlük dosyasının azami boyutuna göre veya belli aralıklarla
     günlük dosyalarını döndürür.

    Seçenekler
    


    
    
    -l
    
    
    GMT yerine yerel zamanın kullanılmasını sağlar.
    

    
    -L bagismi
    
    
    Belirtilen bağ dosyası ismine geçerli günlük dosyasından kalıcı bir bağ
    oluşturulur. tail -F bagismi gibi bir komut kullanılarak
    günlüğün sürekli izlenmesi için kullanılabilir.
    
    
    Bağ ismi mutlak bir yol içermiyorsa, rotatelogs'un çalışma 
    dizinine, rotatelogs sunucu tarafından çalıştırılıyorsa 
    ServerRoot dizinine görelidir.
    
    
    

    
    -p program
    

    
    Belirtildiği takdirde, rotatelogs yeni
    bir günlük dosyasının her açılışında belirtilen programı çalıştırır. Yeni
    açılan dosyanın ismi programa ilk argüman olarak aktarılır. Bu işlem bir
    döndürme sonrası yapılırsa eski günlük dosyası ikinci argüman olarak
    aktarılır. rotatelogs işlemini sürdürmek için
    belirtilen programın sonlanmasını beklemez, dolayısıyla sonlanma soucunda
    döndürülen hata kodunu günlüğe kaydetmez. Çalıştırılan program
    rotatelogs ile aynı stdin, stdout ve stderr'i
    kullanır ve ortamı da miras alır.
    

    
    -f
    
    
    İlk günlük giridisinin okunmasını beklemeden
    rotatelogs başlar başlamaz günlük
    dosyasının açılmasını sağlar. Çok meşgul sitelerde, sunucu başlatılıp ilk
    istek sunuluncaya kadar geçen zamanda günlük dosyasının yokluğu
    özdevinimli işlemler yapan bazı günlükleme araçlarında sorunlara yol
    açabilir. Bu seçenek bu gibi durumlarda yararlıdır.
    

    
    -D
    
    
    Günlük dosyasının yerleştirileceği dizini (eğer yoksa) üst dizinleri ile 
    birlikte yapılandırır. Bu, strftime(3) işlevinin sırf dosya için 
    değil yol için de kullanılmasını sağlar.
    

    
    -t
    
    
    Günlük dosyasının döndürülmek yerine tepeden kırpılmasına sebep olur.
    Günlüğün tail gibi bir araç tarafından gerçek
    zamanda işlendiği ve veriyi saklamanın gerekmediği durumda kullanışlıdır.
    Dosya ismine bir sonek eklenmez, ancak biçem dizgesi '%' karakteri
    içeriyorsa buna uyulur.
    

    
    -v
    
    
    Standart hataya verilen çıktı daha ayrıntılı olur. Çıktı,
    yapılandırma çözümlemesinin sonuçlarını ve tüm dosya açma/kapama
    işlemlerini içerir.
    

    
    -e
    
    
    Günlüğü standart çıktıya basar. Günlüğün zincirdeki ilgili araç
    tarafından gerçek zamanda işlenmesi gerektiğinde kullanışlıdır.
    

    
    -c
    
    
    Create log file for each interval, even if empty.
    

    
    -n dosya_sayısı
    
    
    Zaman damgalarına bakılmaksızın bir dosya serisi açılır. Örneğin -n3
      belirtilirse "logfile", "logfile.1", "logfile.2" serisi açılır ve
      "logfile" üzerine yazılır.
      2.4.5 ve sonraki sürümler içindir.
    

    
    dosyaismi
    
    
    Günlük dosyasının ismi yoluyla birlikte belirtilir.
      dosyaismi '%' karakterleri içeriyorsa bunlar
      strftime(3) biçem belirteçleri olarak ele alınır. Aksi
      takdirde, özdevinimli olarak .nnnnnnnnnn uzantısı üretilir.
      (-t seçeneği kullanılmadıkça) Uzantı saniye
      cinsindendir  ve her iki durumda da bu değer, mevcut döngü
      diliminin başlangıcına göre hesaplanır. Örneğin, döndürmenin 86400
      saniyede bir yapılacağı belirtilmişse, strftime(3) biçeminde
      oluşturulan saat, dakika ve saniye alanları, 24 saatlik sürenin
      başlangıcını (geceyarısı) göstermek üzere sıfırlarla doldurulur.
    

      
    strftime(3) dosyaismi biçemlemesi kullanılırken, günlük
      dosyası biçeminin günlük dosyası döndürülürken her zaman farklı bir dosya
      ismi üretecek yeterlilikte parçacıklı yapıya sahip olduğundan emin
      olmalısınız. Aks takdirde döndürme işlemi yeni bir dosya başlatmak yerine
      hep aynı dosyanın üzerine yazar. Örneğin, logfile için
      /var/log/errorlog.%Y-%m-%d belirtilmişse 5 mega baytta bir
      yeni bir günlük dosyasına başlanacaktır. Fakat 5 megabayta gün içinde iki
      kez ulaşılırsa aynı günlük dosyası üretilir ve günlük hep aynı dosyanın
      üzerine yazılır.
    
      
    Günlük dosyası mutlak bir yol içermiyorsa, rotatelogs'un 
      çalışma dizinine, rotatelogs sunucu tarafından 
      çalıştırılıyorsa ServerRoot 
      dizinine görelidir.
    
    
    

    
    süre
    
    
    Günlük dosyasının yenisinin kaç saniyede bir açılacağı belirtilir.
    Örneğin, bu süre 3600 saniye ise günlük dosyası her saat başında
    yenilenir; 86400 saniye ise her geceyarısı yenilenir. (Bu süre zarfında
    günlüğe kaydedilecek bir olay gerçekleşmemişse dosya oluşturulmaz.)
    

    
    boyut(B|K|M|G)
    
    
    Boyuta göre döndürme için azami dosya boyutu. Belirtilenin bir süre
    değil de bir boyut değeri olarak ele alınması için değerin sonuna şu
    karakterlerden biri eklenmelidir: B (Bayt), K
    (kilobayt), M (megabayt), G (gigabayt).

    
    Süre ve boyut birlikte belirtilmişse boyut süreden sonra
    belirtilmelidir. Dosya yenilemesi, bunlardan hangisi daha önce aşılırsa o
    zaman gerçekleşir.
    

    
    saat_farkı
    
    
    Koordinatlı evrensel zamana göre "dakika" farkı. Belirtilmezse, sıfır
    öntanımlıdır. Örneğin, -5 saatlik bir zaman diliminde bulunuyorsanız bu
    değer -300 olmalıdır. Çoğu durumda, bunun yerine
    -l seçeneğini kullanmak gerekir.

    Örnekler
    


    
     CustomLog "|bin/rotatelogs /var/log/logfile 86400" common

    

     
    nnnn, günlük kaydının başladığı sistem zamanı olmak üzere
     /var/log/logfile.nnnn dosyası oluşturulur. Bu zaman, daima döngü
     süresinin katları olacağından bunu cron betiklerinizi eşzamanlamakta
     kullanabilirsiniz. Her döngü süresinin sonunda (burada 24 saat sonra)
     yeni bir günlük dosyası açılır.
    


    
     CustomLog "|bin/rotatelogs -l /var/log/logfile.%Y.%m.%d 86400" common

    

     
    yyyy, yıl; mm, ay; dd, ayın gününü belirtmek üzere
     /var/log/logfile.yyyy.mm.dd dosyası oluşturulur. Her gün yerel zamanla
     geceyarısı yeni bir günlük dosyasına geçilecektir.
    


    
     CustomLog "|bin/rotatelogs /var/log/logfile 5M" common

    

     
    Günlük dosyası 5 megabaytlık olunca yenisinin oluşturulmasını sağlar.
     
    


    
     ErrorLog "|bin/rotatelogs /var/log/errorlog.%Y-%m-%d-%H_%M_%S 5M"

    
     
    Hata günlüğünün 5 megabaytta bir
     errorlog.YYYY-mm-dd-HH_MM_SS biçemli bir isimle
     oluşturulmasını sağlar.
    


    
     CustomLog "|bin/rotatelogs -t /var/log/logfile 86400" common

    

     
    /var/log/logfile dosyasını oluşturur, sunucu başlatılırken ve günde
       bir kere dosyanın tepesi kırpılır. Bu senaryoda ayrı bir sürecin (tail
       gibi) dosyayı gerçek zamanlı işleyeceği umulur.

    htcacheclean,
    mod_cache_disk deposunun boyutlarını belli sınırlar
    içinde veya kullanımdaki dosya düğümlerinin sınırları içinde tutmak için
    kullanılır. Bu araç ya elle ya da bir artalan süreci
    olarak çalıştırılır. Artalan süreci olarak çalıştırıldığında, silinecek
    arabellek içeriğini tespit etmek için arabellek dizinlerine belli
    aralıklarla bakmak dışında uykuda olur. Artalan sürecini temiz olarak
    durdurmak için TERM veya INT sinyali göndermeniz yeterlidir. Elle
    çalıştırıldığında, silinecek arabellek içeriğini tespit etmek için
    arabellek dizinlerine bir kereliğine bakar. Bir veya daha fazla URL
    belirtilmesi durumunda arabellekte olanlar arabellekten silinir.

    Seçenekler
    
    
    
    
    -d süre
    
    
    Artalanda çalışarak süre dakikada bir
    arabelleği temizler. Bu seçenek -D,
    -v ve -r
    seçenekleri ile birlikte kullanılamaz. Artalan sürecini temiz olarak
    sonlandırmak için SIGTERM veya SIGINT göndermek
    yeterlidir.
    

    
    -D
    
    
    Kuru kuruya çalışıp, hiçbir şeyi silmez.
    -d seçeneği ile birlikte kullanılamaz. Kuru
    çalıştırma sırasında -t seçeneği ile dizinler
    silinmek istenirse, statlarda silinmiş görünen dosya düğümleri silinmiş
    dizinler olarak hesaba katılmaz ve tahmini olarak imlenir.
    

    
    -v
    
    
    Çıktı daha ayrıntılı olur. -d seçeneği
    ile birlikte kullanılamaz.
    

    
    -r
    
    
    İyice temizlik yapılır. Bunun için Apache HTTP sunucusunun
    çalışmadığı varsayılır (aksi takdirde arabellek içeriği bozulabilir).
    -t seçeneğinin de uygulanmasını sağlar.
    -d seçeneği ile birlikte kullanılamaz.
    

    
    -n
    
    
    Nazik olur. Diğer süreçlerin yararına daha yavaş çalışır. (a) disk
    G/Ç işlemlerinde gecikmeler olursa ve (b) çekirdek bu arada başka bir
    süreci öne çekmişse htcacheclean uyumayı
    tercih edecektir.
    

    
    -t
    
    
    Tüm boş dizinleri siler. Öntanımlı olarak, sadece arabellek dosyaları
    silinirse de bazı yapılandırmalarda büyük miktarda dizin oluşturulması bu
    seçeneğin kullanılmasını gerektirebilir. Yapılandırmanız çok sayıda dizin
    gerektiriyorsa ve dosya düğümlerinin veya dosya ayırma tablolarının
    tükenmesi sözkonusu ise bu seçeneğin kullanılması önerilir.
    

    
    -p yol
    
    
    yol, disk arabelleğinin kök dizini olarak
    belirtilir. CacheRoot
    yönergesinde belirtilen dizin olmalıdır.
    

    
    -Ppiddosyası
    
    
    Artalan süreci olarak çalışmada süreç kimliğinin yazılacağı dosyanın
    adını belirtmek için kullanılır.
    

    
    -Rboyut
    
    
    Disk bloklarının boyunu denkleştirmek için yuvarlanacak üst boyutu
    belirtmekte kullanılır. Arabellek bölümünün blok boyutunu belirler.
    

    
    -l sınır
    
    
    sınır, disk arabelleğinin toplam boyutu
    olarak belirtilir. Değerin öntanımlı olarak bayt cinsinden belirtileceği
    varsayılır. Değerin sonuna kilobayt için K, megabayt
    M, Gbayt için G  harfi konulabilir.
    

    
    -Llimit
    
    
    Disk arabellek dosyası düğümü toplamının sınırını belirlemekte
    kullanılır. Değerin sonuna kilobayt için K, megabayt
    M, Gbayt için G  harfi konulabilir.
    

    
    -i
    
    
    Akıllı olup sadece disk arabelleği değiştiği zaman çalışır. Bu
    seçenek -d seçeneği ile birlikte
    belirtilmek zorundadır.
    

    
    -a
    
    
    O an arabellekte saklanmakta olan URL'leri listeler. Birden fazla aynı
    URL varsa yalnız biri listelenir.
    

    
    -A
    
    
    O an arabellekte saklanmakta olan URL'leri öznitelikleri ile listeler.
    Öznitelikler şu sırayla verilir: url, header size, body size, status,
    entity version, date, expiry, request time, response time, body present,
    head request
    
    
    

    top
    

    

    Belli bir URL'nin silinmesi
    
    
    htcacheclean tarafından aktarılan URL'ler
    arabellekten silinir. Bir URL birden fazla mevcutsa hepsi silinir.
    

    
    Ters vekilli bir URL silinmişse, etkin URL Host başlığı
    port, yol ve sorgu ile
    oluşturulur. Bir sorgu dizgesi olsun olmasın, URL içinde '?' daima açıkça
    belirtilmelidir. Örneğin, localhost sunucusundaki
    / yolu silinmek istenirse silinecek URL
    http://localhost:80/? olurdu.
    


    top
    

    

    Arabellekteki URL'lerin listelenmesi
    
    
    htcacheclean'e
    -a veya -A
    seçeneğinin aktarılmasıyla, arabellekteki URL'ler bulundukça her satıra bir
    URL gelecek biçemde listelenir. -A seçeneği
    URL'nin ardından arabellek içeriğini tamamını şu sırayla dökümler:
    

    
    
        
    url
    Öğenin URL'si.
    
        
    header size
    Bayt cinsinden başlık uzunluğu.
    
        
    body size
    Bayt cinsinden gövde uzunluğu.
    
        
    status
    Arabellekteki yanıtın durumu.
    
        
    entity version
    Öğenin silinmeksizin kaç kere
          doğrulandığı.
    
        
    date
    Yanıt tarihi.
    
        
    expiry
    Yanıtın zaman aşımı tarihi.
    
        
    request time
    İsteğin başlama zamanı.
    
        
    response time
    İsteğin bitiş zamanı.
    
        
    body present
    0 ise istekle birlikte gövde saklanmaz, 1 ise
          saklanır.
    
        
    head request
    1 ise, öğe, gövde olmaksızın arabellekli bir
          HEAD isteği içerir, 0 ise içermez.
    
    
    

    top
    

    

    Çıkış Durumu
    
    
    htcacheclean, tüm işlemler başarıyla
    yerine getirildiğinde 0, aksi takdirde 1
    döndürür. Bir URL belirtildiğinde, bu URL arablleklenmi ve silinmişse
    0, aksi takdirde 2 döndürür. URL'nin silinmesi
    sırasında bir hata oluşursa 1 döndürür.

    htdbm permet de manipuler des fichiers au format DBM
    ou sont stockés des nom d'utilisateurs et mots de passe à des fins
    d'authentification de base des utilisateurs HTTP via le module
    mod_authn_dbm. Voir la documentation de
    dbmmanage pour plus de détails à propos de ces
    fichiers DBM.

    Options
    
    
    
    
    -b
    
    
    Utilise le mode batch ; en d'autres termes, le mot de passe est
    extrait de la ligne de commande au lieu d'être demandé à
    l'opérateur. Cette option doit être utilisée avec la plus grande
    prudence, car le mot de passe est visible en clair
    dans la ligne de commande. Pour utiliser un script, voir l'option
    -i.
    

    
    -i
    
    
    Lit le mot de passe depuis stdin sans vérification (à utiliser
    dans le cadre d'un script).
    

    
    -c
    
    
    Crée le fichier-mots-de-passe. Si
    fichier-mots-de-passe existe déjà, il est réécrit et
    tronqué. Cette option ne peut pas être combinée avec l'option
    -n.
    

    
    -n
    
    
    Affiche les résultats sur la sortie standard et ne met pas à
    jour la base de données. Cette option modifie la syntaxe de la ligne
    de commande, car l'argument fichier-mots-de-passe (en
    général le premier) est omis. Elle ne peut pas être combinée avec
    l'option -c.
    

    
    -m
    
    
    Utilise un chiffrement MD5 pour les mots de passe. Sous Windows
    et Netware, c'est l'option par défaut..
    

    
    -B
    
    
    Utilise l'algorythme de chiffrement bcrypt pour les mots de
    passe. C'est un algorythme actuellement considéré comme sûr.
    

    
    -C
    
    
    Ce drapeau n'est autorisé qu'en conjonction avec le drapeau
    -B (chiffrement bcrypt). Il permet de définir la durée
    de traitement pour l'algorythme de chiffrement bcrypt (plus elle est
    longue, plus la sécurité est élevée, mais la rapidité est diminuée
    d'autant) ; la valeur par défaut est 5, les valeurs valides vont de
    4 à 31.
    


    
    -d
    
    
    Utilise un chiffrement crypt() pour les mots de
    passe. C'est l'option par défaut sur toutes les plates-formes, sauf
    Windows et Netware. Bien que htdbm supporte ce
    chiffrement sur toutes les plates-formes, il n'est pas supporté par
    le serveur httpd sous Windows et Netware. Cet
    algorythme est considéré comme non sûr selon les
    standards actuels.
    

    
    -s
    
    
    Utilise le chiffrement SHA pour les mots de passe. Facilite la
    migration vers/depuis les serveurs Netscape qui utilisent le format
    LDAP Directory Interchange (ldif). Cet
    algorythme est considéré comme non sûr selon les
    standards actuels.
    

    
    -p
    
    
    Utilise des mots de passe au format texte en clair. Bien que
    htdbm supporte ce format sur toutes les plates-formes,
    le démon httpd n'accepte les mots de passe au
    format texte en clair que sous Windows et Netware.
    

    
    -l
    
    
    Affiche chaque nom d'utilisateur de la base de données
    accompagné de son commentaire sur la sortie standard.
    

    
    -v
    
    
    Vérifie une association nom d'utilisateur/mot de passe. Le
    programme affichera un message indiquant si le mot de passe fourni
    est valide. Si le mot de passe n'est pas valide, le programme
    s'arrête et renvoie un code d'erreur 3.
    

    
    -x
    
    
    Supprime l'utilisateur. Si le nom d'utilisateur existe dans le
    fichier DBM spécifié, il sera supprimé.
    

    
    -t
    
    
    Interprète le dernier paramètre en tant que commentaire. Avec
    cette option, il est possible d'ajouter une chaîne supplémentaire à
    la fin de la ligne de commande ; le contenu de cette chaîne sera
    stocké dans la base de données dans le champ "Comment" associé au
    nom d'utilisateur spécifié.
    

    
    nom-fichier
    
    
    Le nom du fichier au format DBM en général sans l'extension
    .db, .pag, ou .dir. Avec
    l'option -c, le fichier DBM est mis à jour s'il existe
    ou créé dans le cas contraire.
    

    
    nom-utilisateur
    
    
    Le nom d'utilisateur à créer ou mettre à jour dans le
    fichier-mots-de-passe. Si nom-utilisateur
    n'existe pas dans ce fichier, une entrée est ajoutée. S'il existe,
    son mot de passe est modifié.
    

    
    mot-de-passe
    
    
    Le mot de passe en clair destiné à être chiffré et stocké dans
    le fichier DBM. Ne s'utilise qu'avec l'option -b.
    

    
    -TDBTYPE
    
    
    Type de fichier DBM (SDBM, GDBM, DB, ou "default").
    
    
    

    top
    

    

    Bugs
    
    
    Vous devez garder à l'esprit qu'il existe de nombreux formats de
    fichiers DBM différents, et que selon toute vraisemblance, des
    bibliothèques pour plus d'un format sont présentes sur votre
    système. Les trois exemples de base sont SDBM, NDBM, le projet GNU
    GDBM, et Berkeley/Sleepycat DB 2/3/4. Malheureusement, toutes ces
    bibliothèques
    utilisent des formats de fichiers différents, et vous devez vous
    assurer que le format de fichier utilisé par nom-fichier
    correspond au format attendu par htdbm.
    Actuellement, htdbm n'a aucun moyen de savoir à
    quel type de fichier DBM il a à faire. S'il est utilisé avec un
    format inapproprié, il ne renverra rien, ou pourra créer un fichier
    DBM différent avec un nom différent, ou au pire, va corrompre le
    fichier DBM si vous avez tenté de le modifier.
    

    
    Vous pouvez utiliser le programme file fourni par la
    plupart des systèmes Unix pour déterminer le format d'un fichier
    DBM.

    Valeur renvoyée
    
    
    htdbm renvoie 0 ("true") si les nom d'utilisateur et
    mot de passe ont été créés ou mis à jour avec succès dans le fichier
    DBM. htdbm renvoie 1 s'il a rencontré un
    problème d'accès aux fichiers, 2 si la ligne de
    commande comportait une erreur de syntaxe, 3 si le mot
    de passe a été fourni interactivement et s'il est invalide pour
    l'entrée considérée, 4 si l'opération a été
    interrompue, 5 si une valeur est trop longue (nom
    utilisateur, nom fichier, mot de passe, ou l'enregistrement après
    son élaboration), 6 si le nom d'utilisateur contient
    des caractères illégaux (voir la section Restrictions), et 7 si le
    fichier n'est pas un fichier de mots de passe DBM valide.
    

    top
    

    

    Exemples
    
    
    
      htdbm /usr/local/etc/apache/.utilisateurs-htdbm jsmith
    
    

    
    Ajoute ou modifie le mot de passe de l'utilisateur
    jsmith. Le mot de passe est demandé à l'opérateur. Sous
    Windows, le mot de passe sera chiffré en utilisant l'algorithme MD5
    Apache modifié ; dans les autres cas, c'est la routine
    crypt() du système qui sera utilisée. Si le fichier
    n'existe pas, htdbm s'arrêtera et renverra une
    erreur.
    

    
    
      htdbm -c /home/doe/public_html/.htdbm jane
    
    

    
    Crée un nouveau fichier et y enregistre une entrée pour
    l'utilisateur jane. Le mot de passe est demandé à
    l'opérateur. Si le fichier existe et ne peut pas être lu, ou ne peut
    pas être écrit, il ne sera pas modifié et
    htdbm affichera un message et renverra un code
    d'erreur.
    

    
    
      htdbm -mb /usr/web/.htdbm-tous jones Pwd4Steve
    
    

    
    Chiffre le mot de passe entré avec la ligne de commande
    (Pwd4Steve) à l'aide de l'algorithme MD5, et
    l'enregistre dans le fichier spécifié.
    

    top
    

    

    Considérations à propos de sécurité
    
    
    Les fichiers de mots de passe Web tels que ceux que gère
    htdbm ne doivent pas être stockés dans
    l'espace d'URI du serveur Web -- en d'autres termes, il ne doit pas
    être possible d'y accéder à l'aide d'un navigateur.
    

    
    L'utilisation de l'option -b est déconseillée, car
    lorsqu'il est utilisé, le mot de passe apparaît en clair dans la
    ligne de commande.
    

    
    Notez que lorsque vous utilisez l'algorythme
    crypt(), seuls les 8 premiers caractères du mot de
    passe sont pris en compte. Si le mot de passe fourni est plus long,
    les caractères supplémentaires seront ignorés sans avertissement.
    

    
    L'algorythme SHA ne permet pas de spécifier une valeur
    d'initialisation pour la génération de nombres aléatoires (salting)
    : un mot de passe donné ne possède ainsi qu'une réprésentation
    chiffrée. Les algorythmes crypt() et MD5 permettent quant à
    eux des représentations chiffrées multiples en acceptant comme
    paramètre une chaîne d'initialisation (salt), rendant les attaques à
    base de dictionnaires contre les mots de passe plus difficiles.
    

    
    Les algorythmes SHA et crypt() sont considérés comme
    non sûrs selon les standards actuels.
    

    top
    

    

    Restrictions
    
    
    Sur la plate-forme Windows, les mots de passe chiffrés avec
    htdbm ont une taille limitée à 255
    caractères. Si le mot de passe fourni est plus long, il sera tronqué
    à 255 caractères.
    

    
    L'algorithme MD5 utilisé par htdbm est spécifique à
    Apache ; les mots de passe chiffrés en utilisant cet algorithme
    seront inutilisables sur d'autres serveurs Web.
    

    
    Les noms d'utilisateurs ont une taille limitée à 255
    octets et ne doivent pas contenir de caractère :.

 * For a fairly comprehensive set of languages see the
 * README
 * file that came with this source.  At a minimum, the lexer should work on a
 * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
 * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
 * and a subset of Perl, but, because of commenting conventions, doesn't work on
 * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
 * 
    
 * Usage: 
      
 * 
    1.  include this source file in an html page via
 *   {@code }
 * 
    2.  define style rules.  See the example page for examples.
 * 
    3.  mark the {@code 
      } and {@code } tags in your source with
 *    {@code class=prettyprint.}
 *    You can also use the (html deprecated) {@code } tag, but the pretty
 *    printer needs to do more substantial DOM manipulations to support that, so
 *    some css styles may not be preserved.
 * </ol>
 * That's it.  I wanted to keep the API as simple as possible, so there's no
 * need to specify which language the code is in, but if you wish, you can add
 * another class to the {@code <pre>} or {@code <code>} element to specify the
 * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
 * starts with "lang-" followed by a file extension, specifies the file type.
 * See the "lang-*.js" files in this directory for code that implements
 * per-language file handlers.

    * constant like PR_PLAIN.  index_n-1 <= index_n, and style_n-1 applies to
    * all characters in sourceCode[index_n-1:index_n].
    *
    * The stylePatterns is a list whose elements have the form
    * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
    *
    * Style is a style constant like PR_PLAIN, or can be a string of the
    * form 'lang-FOO', where FOO is a language extension describing the
    * language of the portion of the token in $1 after pattern executes.
    * E.g., if style is 'lang-lisp', and group 1 contains the text
    * '(hello (world))', then that portion of the token will be passed to the
    * registered lisp handler for formatting.
    * The text before and after group 1 will be restyled using this decorator
    * so decorators should take care that this doesn't result in infinite
    * recursion.  For example, the HTML lexer rule for SCRIPT elements looks
    * something like ['lang-js', /<[s]cript>(.+?)<\/script>/].  This may match
    * '<script>foo()<\/script>', which would cause the current decorator to
    * be called with '<script>' which would not match the same rule since
    * group 1 must not be empty, so it would be instead styled as PR_TAG by
    * the generic tag rule.  The handler registered for the 'js' extension would
    * then be called with 'foo()', and finally, the current decorator would
    * be called with '<\/script>' which would not match the original rule and
    * so the generic tag rule would identify it as a tag.
    *
    * Pattern must only match prefixes, and if it matches a prefix, then that
    * match is considered a token with the same style.
    *
    * Context is applied to the last non-whitespace, non-comment token
    * recognized.
    *
    * Shortcut is an optional string of characters, any of which, if the first
    * character, guarantee that this pattern and only this pattern matches.

<h2><a name="req" id="req">Requirements</a></h2>

    

    <p>Apache 2.0 is designed to run on NetWare 6.0 service pack 3
    and above. If you are running a service pack less
    than SP3, you must install the latest
    <a href="http://developer.novell.com/ndk/libc.htm">NetWare Libraries
    for C (LibC)</a>.</p>

    <p>NetWare service packs are available <a href="http://support.novell.com/misc/patlst.htm#nw">here</a>.</p>

    <p>Apache 2.0 for NetWare can also be run in a NetWare 5.1 environment
    as long as the latest service pack or the latest version
    of the <a href="http://developer.novell.com/ndk/libc.htm">NetWare Libraries
    for C (LibC)</a> has been installed .  <strong>WARNING:</strong> Apache 2.0
    for NetWare has not been targeted for or tested in this environment.</p>

<h2><a name="inst" id="inst">Installing Apache for NetWare</a></h2>

    

    <p>There is no Apache install program for NetWare currently. If you
    are building Apache 2.0 for NetWare from source, you will need to
    copy the files over to the server manually.</p>

    <p>Follow these steps to install Apache on NetWare from the
    binary download (assuming you will install to
    <code>sys:/apache2</code>):</p>

    <ul>
      <li>Unzip the binary download file to the root of the <code>SYS:</code>
      volume (may be installed to any volume)</li>

      <li>Edit the <code>httpd.conf</code> file setting <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> and <code class="directive"><a href="../mod/core.html#servername">ServerName</a></code> along with any file path values
      to reflect your correct server settings</li>

      <li>Add <code>SYS:/APACHE2</code> to the search path, for example:
        <div class="example"><p><code>SEARCH ADD SYS:\APACHE2</code></p></div>
      </li>

    </ul>

    <p>Follow these steps to install Apache on NetWare manually
    from your own build source (assuming you will install to
    <code>sys:/apache2</code>):</p>

    <ul>
      <li>Create a directory called <code>Apache2</code> on a
      NetWare volume</li>

      <li>Copy <code>APACHE2.NLM</code>, <code>APRLIB.NLM</code>
      to <code>SYS:/APACHE2</code></li>

      <li>Create a directory under <code>SYS:/APACHE2</code>
      called <code>BIN</code></li>

      <li>Copy <code>HTDIGEST.NLM</code>, <code>HTPASSWD.NLM</code>,
      <code>HTDBM.NLM</code>, <code>LOGRES.NLM</code>, <code>ROTLOGS.NLM</code>
      to <code>SYS:/APACHE2/BIN</code></li>

      <li>Create a directory under <code>SYS:/APACHE2</code>
      called <code>CONF</code></li>

      <li>Copy the <code>HTTPD-STD.CONF</code> file to the
      <code>SYS:/APACHE2/CONF</code> directory and rename to
      <code>HTTPD.CONF</code></li>

      <li>Copy the <code>MIME.TYPES</code>, <code>CHARSET.CONV</code> and
      <code>MAGIC</code> files to <code>SYS:/APACHE2/CONF</code> directory</li>

      <li>Copy all files and subdirectories in <code>\HTTPD-2.0\DOCS\ICONS</code>
      to <code>SYS:/APACHE2/ICONS</code></li>

      <li>Copy all files and subdirectories in <code>\HTTPD-2.0\DOCS\MANUAL</code>
      to <code>SYS:/APACHE2/MANUAL</code></li>

      <li>Copy all files and subdirectories in <code>\HTTPD-2.0\DOCS\ERROR</code>
      to <code>SYS:/APACHE2/ERROR</code></li>

      <li>Copy all files and subdirectories in <code>\HTTPD-2.0\DOCS\DOCROOT</code>
      to <code>SYS:/APACHE2/HTDOCS</code></li>

      <li>Create the directory <code>SYS:/APACHE2/LOGS</code>
      on the server</li>

      <li>Create the directory <code>SYS:/APACHE2/CGI-BIN</code>
      on the server</li>

      <li>Create the directory <code>SYS:/APACHE2/MODULES</code>
      and copy all nlm modules into the <code>modules</code> directory</li>

      <li>Edit the <code>HTTPD.CONF</code> file searching for all
      <code>@@Value@@</code> markers and replacing them with the
      appropriate setting</li>

      <li>Add <code>SYS:/APACHE2</code> to the search path, for example:
        <div class="example"><p><code>SEARCH ADD SYS:\APACHE2</code></p></div>
      </li>
    </ul>

    <p>Apache may be installed to other volumes besides the default <code>SYS</code> volume.</p>

    <p>During the build process, adding the keyword "install" to the makefile command line
    will automatically produce a complete distribution package under the subdirectory
    <code>DIST</code>. Install Apache by simply copying the distribution that was produced
    by the makfiles to the root of a NetWare volume (see: <a href="#comp">Compiling Apache for
    NetWare</a> below).</p>

<div class="section">
<h2><a name="run" id="run">Running Apache for NetWare</a></h2>

    

    <p>To start Apache just type <code>apache</code> at the
    console. This will load apache in the OS address space. If you
    prefer to load Apache in a protected address space you may
    specify the address space with the load statement as follows:</p>

    <div class="example"><p><code>
      load address space = apache2 apache2
    </code></p></div>

    <p>This will load Apache into an address space called apache2.
    Running multiple instances of Apache concurrently on NetWare is
    possible by loading each instance into its own protected
    address space.</p>

    <p>After starting Apache, it will be listening to port 80
    (unless you changed the <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>
    directive in the configuration files).
    To connect to the server and access the default page,
    launch a browser and enter the server's name or address. This
    should respond with a welcome page, and a link to the Apache
    manual. If nothing happens or you get an error, look in the
    <code>error_log</code> file in the <code>logs</code>
    directory.</p>

    <p>Once your basic installation is working, you should
    configure it properly by editing the files in the
    <code>conf</code> directory.</p>

    <p>To unload Apache running in the OS address space just type
    the following at the console:</p>

    <div class="example"><p><code>
      unload apache2
    </code></p></div>

    <p>or</p>

    <div class="example"><p><code>
      apache2 shutdown
    </code></p></div>

    <p>If apache is running in a protected address space specify the
    address space in the unload statement:</p>

    <div class="example"><p><code>
      unload address space = apache2 apache2
    </code></p></div>

    <p>When working with Apache it is important to know how it will
    find the configuration files. You can specify a configuration
    file on the command line in two ways:</p>

    <ul>
      <li><code>-f</code> specifies a path to a particular
      configuration file</li>
    </ul>

    <div class="example"><p><code>
      apache2 -f "vol:/my server/conf/my.conf"
    </code></p></div>

    <div class="example"><p><code>
      apache -f test/test.conf
    </code></p></div>

    <p>In these cases, the proper <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>
    should be set in the configuration file.</p>

    <p>If you don't specify a configuration file name with <code>-f</code>,
    Apache will use the file name compiled into the server, usually
    <code>conf/httpd.conf</code>. Invoking Apache with the <code>-V</code>
    switch will display this value labeled as <code>SERVER_CONFIG_FILE</code>.
    Apache will then determine its <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>
    by trying the following, in this order:</p>

    <ul>
      <li>A <code>ServerRoot</code> directive via a
      <code>-C</code> switch.</li>

      <li>The <code>-d</code> switch on the command line.</li>

      <li>Current working directory</li>

      <li>The server root compiled into the server.</li>
    </ul>

    <p>The server root compiled into the server is usually <code>sys:/apache2</code>.
    invoking apache with the <code>-V</code> switch will display this value labeled as
    <code>HTTPD_ROOT</code>.</p>

    <p>Apache 2.0 for NetWare includes a set of command line directives that can
    be used to modify or display information about the running instance of the
    web server. These directives are only available while Apache is running. Each
    of these directives must be preceded by the keyword <code>APACHE2</code>.</p>

    <dl>
      <dt>RESTART</dt>

<h2><a name="use" id="use">Configuring Apache for NetWare</a></h2>

    

    <p>Apache is configured by reading configuration files usually stored
    in the <code>conf</code> directory. These are the same as files used
    to configure the Unix version, but there are a few different directives for
    Apache on NetWare. See the <a href="../mod/">Apache module
    documentation</a> for all the available directives.</p>

    <p>The main differences in Apache for NetWare are:</p>

    <ul>
      <li>
        <p>Because Apache for NetWare is multithreaded, it does not
        use a separate process for each request, as Apache does on some Unix
        implementations. Instead there are only threads running: a parent
        thread, and multiple child or worker threads which handle the requests.</p>

        <p>Therefore the "process"-management directives are different:</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code> -
        Like the Unix directive, this controls how many connections
        a worker thread will serve before exiting. The recommended default,
        <code>MaxConnectionsPerChild 0</code>, causes the thread to continue servicing
        request indefinitely. It is recommended on NetWare, unless there is some
        specific reason, that this directive always remain set to <code>0</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code> -
        This directive tells the server how many threads it should start initially.
        The recommended default is <code>StartThreads 50</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code> -
        This directive instructs the server to spawn additional worker threads
        if the number of idle threads ever falls below this value. The recommended
        default is <code>MinSpareThreads 10</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code> -
        This directive instructs the server to begin terminating worker threads
        if the number of idle threads ever exceeds this value. The recommended
        default is <code>MaxSpareThreads 100</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_netware.html#maxthreads">MaxThreads</a></code> -
        This directive limits the total number of work threads to a maximum
        value. The recommended default is <code>ThreadsPerChild 250</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#threadstacksize">ThreadStackSize</a></code> -
        This directive tells the server what size of stack to use
        for the individual worker thread. The recommended default
        is <code>ThreadStackSize 65536</code>.</p>
      </li>

      <li>
        <p>The directives that accept filenames as arguments must use
        NetWare filenames instead of Unix names. However, because Apache
        uses Unix-style names internally, forward slashes must be used
        rather than backslashes. It is recommended that all rooted file paths
        begin with a volume name. If omitted, Apache will assume the
        <code>SYS:</code> volume which may not be correct.</p>
      </li>

      <li>
        <p>Apache for NetWare has the ability to load modules at
        runtime, without recompiling the server. If Apache is
        compiled normally, it will install a number of optional
        modules in the <code>\Apache2\modules</code> directory.
        To activate these, or other modules, the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> directive
        must be used. For example, to active the status module, use
        the following:</p>

        <div class="example"><p><code>
          LoadModule status_module modules/status.nlm
        </code></p></div>

        <p>Information on <a href="../mod/mod_so.html#creating">creating loadable
        modules</a> is also available.</p>
      </li>
    </ul>

    <h3><a name="use-add" id="use-add">Additional NetWare specific directives:</a></h3>

      

      <ul>
        <li><code class="directive"><a href="../mod/core.html#cgimapextension">CGIMapExtension</a></code> -
        This directive maps a CGI file extension to a script interpreter.</li>
      </ul>
      <ul>
        <li><code class="directive"><a href="../mod/mod_nw_ssl.html#securelisten">SecureListen</a></code> -
        Enables SSL encryption for a specified port.</li>
      </ul>
      <ul>
        <li><code class="directive"><a href="../mod/mod_nw_ssl.html#nwssltrustedcerts">NWSSLTrustedCerts</a></code> -
        Adds trusted certificates that are used to create secure connections to proxied servers.</li>
      </ul>
      <ul>
        <li><code class="directive"><a href="../mod/mod_nw_ssl.html#nwsslupgradeable">NWSSLUpgradeable</a></code> -
        Allow a connection created on the specified address/port to be upgraded to an SSL connection.</li>
      </ul>

<h2><a name="comp" id="comp">Compiling Apache for NetWare</a></h2>

    

    <p>Compiling Apache requires MetroWerks CodeWarrior 6.x or higher. Once
    Apache has been built, it can be installed to the root of any NetWare
    volume. The default is the <code>sys:/Apache2</code> directory.</p>

    <p>Before running the server you must fill out the <code>conf</code>
    directory. Copy the file <code>HTTPD-STD.CONF</code> from the distribution
    <code>conf</code> directory and rename it to <code>HTTPD.CONF</code>.
    Edit the <code>HTTPD.CONF</code> file searching for all <code>@@Value@@</code>
    markers and replacing them with the appropriate setting. Copy over
    the <code>conf/magic</code> and <code>conf/mime.types</code> files as well.
    Alternatively, a complete distribution can be built by including the keyword
    <code>install</code> when invoking the makefiles.</p>

    <h3><a name="comp-req" id="comp-req">Requirements:</a></h3>

      

      <p>The following development tools are required to build
      Apache 2.0 for NetWare:</p>

      <ul>
        <li>Metrowerks CodeWarrior 6.0 or higher with the
        <a href="http://developer.novell.com/ndk/cwpdk.htm">NetWare PDK 3.0</a>
        or higher.</li>

        <li><a href="http://developer.novell.com/ndk/libc.htm">NetWare Libraries
        for C (LibC)</a></li>

        <li><a href="http://developer.novell.com/ndk/cldap.htm">LDAP Libraries
        for C</a></li>

        <li><a href="http://www.gzip.org/zlib/">ZLIB Compression Library source code</a></li>

        <li>AWK utility (awk, gawk or similar). AWK can be downloaded from
        <a href="http://developer.novell.com/ndk/apache.htm">http://developer.novell.com/ndk/apache.htm</a>.
        The utility must be found in your windows path and must be named <code>awk.exe</code>.</li>

        <li>To build using the makefiles, you will need GNU make version 3.78.1 (GMake) available at
        <a href="http://developer.novell.com/ndk/apache.htm">http://developer.novell.com/ndk/apache.htm</a>.</li>
      </ul>

    

    <h3><a name="comp-make" id="comp-make">Building Apache using the NetWare makefiles:</a></h3>

      

      <ul>
        <li>Set the environment variable <code>NOVELLLIBC</code> to the
        location of the NetWare Libraries for C SDK, for example:
        <div class="example"><p><code>Set NOVELLLIBC=c:\novell\ndk\libc</code></p></div>
        </li>

        <li>Set the environment variable <code>METROWERKS</code> to the
        location where you installed the Metrowerks CodeWarrior compiler,
        for example:
        <div class="example"><p><code>Set METROWERKS=C:\Program Files\Metrowerks\CodeWarrior</code></p></div>
        If you installed to the default location <code>C:\Program
        Files\Metrowerks\CodeWarrior</code>, you don't need to set this.</li>

        <li>Set the environment variable <code>LDAPSDK</code> to the
        location where you installed the LDAP Libraries for C, for example:
        <div class="example"><p><code>Set LDAPSDK=c:\Novell\NDK\cldapsdk\NetWare\libc</code></p></div>
        </li>

        <li>Set the environment variable <code>ZLIBSDK</code> to the
        location where you installed the source code for the ZLib Library,
        for example:
        <div class="example"><p><code>Set ZLIBSDK=D:\NOVELL\zlib</code></p></div>
        </li>

        <li>Set the environment variable <code>PCRESDK</code> to the location
        where you installed the source code for the PCRE Library, for example:
        <div class="example"><p><code>Set PCRESDK=D:\NOVELL\pcre</code></p></div>
        </li>

        <li>Set the environment variable <code>AP_WORK</code> to the full path of
        the <code>httpd</code> source code directory.
        <div class="example"><p><code>Set AP_WORK=D:\httpd-2.0.x</code></p></div>
        </li>

        <li>Set the environment variable <code>APR_WORK</code> to the full path of
        the <code>apr</code> source code directory. Typically <code>\httpd\srclib\apr</code>
        but the APR project can be outside of the httpd directory structure.
        <div class="example"><p><code>Set APR_WORK=D:\apr-1.x.x</code></p></div>
        </li>

        <li>Set the environment variable <code>APU_WORK</code> to the full path of
        the <code>apr-util</code> source code directory. Typically <code>\httpd\srclib\apr-util</code>
        but the APR-UTIL project can be outside of the httpd directory structure.
        <div class="example"><p><code>Set APU_WORK=D:\apr-util-1.x.x</code></p></div>
        </li>

        <li>Make sure that the path to the AWK utility and the GNU make utility
        (<code>gmake.exe</code>) have been included in the system's
        <code>PATH</code> environment variable.</li>

        <li>Download the source code and unzip to an appropriate directory on
        your workstation.</li>

        <li>Change directory to <code>\httpd-2.0</code> and build the prebuild utilities
        by running "<code>gmake -f nwgnumakefile prebuild</code>". This target will create
        the directory <code>\httpd-2.0\nwprebuild</code> and copy each of the utilities
        to this location that are necessary to complete the following build steps.
        </li>

        <li>Copy the files <code>\httpd-2.0\nwprebuild\GENCHARS.nlm</code> and
        <code>\httpd-2.0\nwprebuild\DFTABLES.nlm</code> to the <code>SYS:</code> volume of a
        NetWare server and run them using the following commands:
          <div class="example"><p><code>
            SYS:\genchars &gt; sys:\test_char.h<br />
            SYS:\dftables sys:\chartables.c<br />
          </code></p></div>
        </li>

        <li>Copy the files <code>test_char.h</code> and <code>chartables.c</code>
        to the directory <code>\httpd-2.0\os\netware</code> on the build machine.</li>

        <li>Change directory to <code>\httpd-2.0</code> and build Apache by running
        "<code>gmake -f nwgnumakefile</code>". You can create a distribution directory by
        adding an install parameter to the command, for example:
        <div class="example"><p><code>gmake -f nwgnumakefile install</code></p></div>
        </li>
      </ul>

    

    <h3><a name="comp-add" id="comp-add">Additional make options</a></h3>

        <div class="example"><p><code>Set USE_STDSOCKETS=1</code></p></div>
        </li>

      </ul>

    

    <h3><a name="comp-mod_ssl" id="comp-mod_ssl">Building mod_ssl for the NetWare platform</a></h3>

      

      <p>By default Apache for NetWare uses the built-in module
      <code class="module"><a href="../mod/mod_nw_ssl.html">mod_nw_ssl</a></code> to provide SSL services.  This module
      simply enables the native SSL services implemented in NetWare OS
      to handle all encryption for a given port.  Alternatively, mod_ssl
      can also be used in the same manner as on other platforms.</p>

      <p>Before mod_ssl can be built for the NetWare platform, the OpenSSL
      libraries must be provided.  This can be done through the following
      steps:</p>

      <ul>
          <li>Download the recent OpenSSL 0.9.8 release source code from the
          <a href="http://www.openssl.org/source/">OpenSSL Source</a>
          page (older 0.9.7 versions need to be patched and are therefore not
          recommended).</li>

          <li>Edit the file <code>NetWare/set_env.bat</code> and modify any
          tools and utilities paths so that they correspond to your build
          environment.</li>

          <li>From the root of the OpenSSL source directory, run the following
          scripts:
          <div class="example"><p><code>
              Netware\set_env netware-libc<br />
              Netware\build netware-libc
          </code></p></div>
          For performance reasons you should enable to build with ASM code.
          Download NASM from the <a href="http://nasm.sourceforge.net/">SF site</a>.
          Then configure OpenSSL to use ASM code:
          <div class="example"><p><code>
              Netware\build netware-libc nw-nasm enable-mdc2 enable-md5
          </code></p></div>
          Warning: don't use the CodeWarrior Assembler - it produces broken code!
          </li>

          <li>Before building Apache, set the environment variable
          <code>OSSLSDK</code> to the full path to the root of the openssl
          source code directory, and set WITH_MOD_SSL to 1.
          <div class="example"><p><code>
              Set OSSLSDK=d:\openssl-0.9.8x<br />
              Set WITH_MOD_SSL=1
          </code></p></div></li>

      </ul>

    <p>While many distributions make Apache httpd available as operating system
    supported packages, it can sometimes be desirable to install and use the
    canonical version of Apache httpd on these systems, replacing the natively
    provided versions of the packages.</p>

    <p>While the Apache httpd project does not currently create binary RPMs
    for the various distributions out there, it is easy to build your own
    binary RPMs from the canonical Apache httpd tarball.</p>

    <p>This document explains how to build, install, configure and run
    Apache httpd 2.4 under Unix systems supporting the RPM packaging format.</p>

<h2><a name="default" id="default">Configuring the Default Instance of Apache httpd</a></h2>
    

    <p>The default configuration for the server is installed by default
    beneath the <code>/etc/httpd</code> directory, with logs written by
    default to <code>/var/log/httpd</code>. The environment for the

<h2><a name="additional" id="additional">Configuring Additional Instances of Apache httpd on the Same Machine</a></h2>
    

    <p>It is possible to configure additional instances of the Apache
    httpd server running independently alongside each other on the same
    machine. These instances can have independent configurations, and
    can potentially run as separate users if so configured.</p>

    <p>This was done by making the httpd startup script aware of its own
    name. This name is then used to find the environment file for the
    server, and in turn, the server root of the server instance.</p>

    <p>To create an additional instance called
    <code>httpd-additional</code>, follow these steps:</p>

    <ul>
      <li>Create a symbolic link to the startup script for the additional
      server:

      <div class="example"><p><code>
        ln -s /etc/rc.d/init.d/httpd /etc/rc.d/init.d/httpd-additional<br />
        chkconfig --add httpd-additional
      </code></p></div>

      </li>

      <li>Create an environment file for the server, using the
      <code>/etc/sysconfig/httpd</code> file as a template:

      <div class="example"><p><code>
        # template from httpd<br />
        cp /etc/sysconfig/httpd /etc/sysconfig/httpd-additional
      </code></p></div>
      
      <div class="example"><p><code>
        # blank template<br />
        touch /etc/sysconfig/httpd-additional
      </code></p></div>

      Edit <code>/etc/sysconfig/httpd-additional</code> and pass the
      server root of the new server instance within the
      <code>OPTIONS</code> environment variable.

      <div class="example"><p><code>
        OPTIONS="-d /etc/httpd-additional -f conf/httpd-additional.conf"
      </code></p></div>

      </li>

      <li>Edit the server configuration file
      <code>/etc/httpd-additional/conf/httpd-additional.conf</code> to
      ensure the correct ports and paths are configured.
      </li>

      <li>Start the server as follows:

      <div class="example"><p><code>
        service httpd-additional restart
      </code></p></div>

      </li>

      <li>Repeat this process as required for each server instance.</li>
    </ul>

<h2><a name="overview" id="overview">Overview of the Apache EBCDIC Port</a></h2>

    

    <p>Version 1.3 of the Apache HTTP Server was the first version
    which included a port to a (non-ASCII) mainframe machine which
    uses the EBCDIC character set as its native codeset.</p>

    <p>(It is the SIEMENS family of mainframes running the <a href="http://www.siemens.de/servers/bs2osd/osdbc_us.htm">BS2000/OSD
    operating system</a>. This mainframe OS nowadays features a
    SVR4-derived POSIX subsystem).</p>

    <p>The port was started initially to</p>

    <ul>
      <li>prove the feasibility of porting <a href="http://httpd.apache.org/">the Apache HTTP server</a> to
      this platform</li>

      <li>find a "worthy and capable" successor for the venerable
      <a href="http://www.w3.org/Daemon/">CERN-3.0</a> daemon
      (which was ported a couple of years ago), and to</li>

      <li>prove that Apache's preforking process model can on this
      platform easily outperform the accept-fork-serve model used
      by CERN by a factor of 5 or more.</li>
    </ul>

    <p>This document serves as a rationale to describe some of the
    design decisions of the port to this machine.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="design" id="design">Design Goals</a></h2>

    

    <p>One objective of the EBCDIC port was to maintain enough
    backwards compatibility with the (EBCDIC) CERN server to make
    the transition to the new server attractive and easy. This
    required the addition of a configurable method to define
    whether a HTML document was stored in ASCII (the only format
    accepted by the old server) or in EBCDIC (the native document
    format in the POSIX subsystem, and therefore the only realistic
    format in which the other POSIX tools like <code>grep</code> or
    <code>sed</code> could operate on the documents). The current
    solution to this is a "pseudo-MIME-format" which is intercepted
    and interpreted by the Apache server (see below). Future versions
    might solve the problem by defining an "ebcdic-handler" for all
    documents which must be converted.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="technical" id="technical">Technical Solution</a></h2>

    

    <p>Since all Apache input and output is based upon the BUFF
    data type and its methods, the easiest solution was to add the
    conversion to the BUFF handling routines. The conversion must
    be settable at any time, so a BUFF flag was added which defines
    whether a BUFF object has currently enabled conversion or not.
    This flag is modified at several points in the HTTP
    protocol:</p>

    <ul>
      <li><strong>set</strong> before a request is received
      (because the request and the request header lines are always
      in ASCII format)</li>

      <li><strong>set/unset</strong> when the request body is
      received - depending on the content type of the request body
      (because the request body may contain ASCII text or a binary
      file)</li>

      <li><strong>set</strong> before a reply header is sent
      (because the response header lines are always in ASCII
      format)</li>

      <li><strong>set/unset</strong> when the response body is sent
      - depending on the content type of the response body (because
      the response body may contain text or a binary file)</li>
    </ul>

    <ol>
      <li>
        <p>The relevant changes in the source are <code>#ifdef</code>'ed
        into two categories:</p>

        <dl>
          <dt><code><strong>#ifdef
          CHARSET_EBCDIC</strong></code></dt>

          <dd>
            <p>Code which is needed for any EBCDIC based machine.
            This includes character translations, differences in
            contiguity of the two character sets, flags which
            indicate which part of the HTTP protocol has to be
            converted and which part doesn't <em>etc.</em></p>
          </dd>

          <dt><code><strong>#ifdef _OSD_POSIX</strong></code></dt>

          <dd>
            <p>Code which is needed for the SIEMENS BS2000/OSD
            mainframe platform only. This deals with include file
            differences and socket implementation topics which are
            only required on the BS2000/OSD platform.</p>
          </dd>
        </dl>
      </li>

      <li>
        <p>The possibility to translate between ASCII and EBCDIC at
        the socket level (on BS2000 POSIX, there is a socket option
        which supports this) was intentionally <em>not</em> chosen,
        because the byte stream at the HTTP protocol level consists
        of a mixture of protocol related strings and non-protocol
        related raw file data. HTTP protocol strings are always
        encoded in ASCII (the <code>GET</code> request, any Header: lines,
        the chunking information <em>etc.</em>) whereas the file transfer
        parts (<em>i.e.</em>, GIF images, CGI output <em>etc.</em>)
        should usually be just "passed through" by the server. This
        separation between "protocol string" and "raw data" is
        reflected in the server code by functions like <code>bgets()</code>
        or <code>rvputs()</code> for strings, and functions like
        <code>bwrite()</code> for binary data. A global translation
        of everything would therefore be inadequate.</p>

        <p>(In the case of text files of course, provisions must be
        made so that EBCDIC documents are always served in
        ASCII)</p>
      </li>

      <li>
        <p>This port therefore features a built-in protocol level
        conversion for the server-internal strings (which the
        compiler translated to EBCDIC strings) and thus for all
        server-generated documents. The hard coded ASCII escapes
        <code>\012</code> and <code>\015</code> which are ubiquitous
        in the server code are an exception: they are already the binary
        encoding of the ASCII <code>\n</code> and <code>\r</code> and
        must not be converted to ASCII a second time.
        This exception is only relevant for server-generated strings;
        and <em>external</em> EBCDIC documents are not expected to
        contain ASCII newline characters.</p>
      </li>

      <li>
        <p>By examining the call hierarchy for the BUFF management
        routines, I added an "ebcdic/ascii conversion layer" which
        would be crossed on every puts/write/get/gets, and a
        conversion flag which allowed enabling/disabling the
        conversions on-the-fly. Usually, a document crosses this
        layer twice from its origin source (a file or CGI output) to
        its destination (the requesting client): <code>file -&gt;
        Apache</code>, and <code>Apache -&gt; client</code>.</p>

        <p>The server can now read the header lines of a CGI-script
        output in EBCDIC format, and then find out that the remainder
        of the script's output is in ASCII (like in the case of the
        output of a WWW Counter program: the document body contains a
        GIF image). All header processing is done in the native
        EBCDIC format; the server then determines, based on the type
        of document being served, whether the document body (except
        for the chunking information, of course) is in ASCII already
        or must be converted from EBCDIC.</p>
      </li>

      <li>
        <p>For Text documents (MIME types text/plain, text/html
        <em>etc.</em>), an implicit translation to ASCII can be
        used, or (if the users prefer to store some documents in
        raw ASCII form for faster serving, or because the files
        reside on a NFS-mounted directory tree) can be served
        without conversion.</p>

        <p><strong>Example:</strong></p>

        <p>to serve files with the suffix <code>.ahtml</code> as a
        raw ASCII <code>text/html</code> document without implicit
        conversion (and suffix <code>.ascii</code> as ASCII
        <code>text/plain</code>), use the directives:</p>

        <div class="example"><p><code>
          AddType  text/x-ascii-html  .ahtml <br />
          AddType  text/x-ascii-plain .ascii
        </code></p></div>

        <p>Similarly, any <code>text/foo</code> MIME type can be
        served as "raw ASCII" by configuring a MIME type
        "<code>text/x-ascii-foo</code>" for it using
        <code>AddType</code>.</p>
      </li>

      <li>
        <p>Non-text documents are always served "binary" without
        conversion. This seems to be the most sensible choice for,
        .<em>e.g.</em>, GIF/ZIP/AU file types. This of course
        requires the user to copy them to the mainframe host using
        the "<code>rcp -b</code>" binary switch.</p>
      </li>

      <li>
        <p>Server parsed files are always assumed to be in native
        (<em>i.e.</em>, EBCDIC) format as used on the machine, and
        are converted after processing.</p>
      </li>

      <li>
        <p>For CGI output, the CGI script determines whether a
        conversion is needed or not: by setting the appropriate
        Content-Type, text files can be converted, or GIF output can
        be passed through unmodified. An example for the latter case
        is the wwwcount program which we ported as well.</p>
      </li>

    </ol>

<h2><a name="document" id="document">Document Storage Notes</a></h2>

    

    <h3><a name="binary" id="binary">Binary Files</a></h3>

      

      <p>All files with a <code>Content-Type:</code> which does not
      start with <code>text/</code> are regarded as <em>binary
      files</em> by the server and are not subject to any conversion.
      Examples for binary files are GIF images, gzip-compressed files
      and the like.</p>

      <p>When exchanging binary files between the mainframe host and
      a Unix machine or Windows PC, be sure to use the ftp "binary"
      (<code>TYPE I</code>) command, or use the
      <code>rcp -b</code> command from the mainframe host (the
      <code>-b</code> switch is not supported in unix
      <code>rcp</code>'s).</p>

    

    <h3><a name="text" id="text">Text Documents</a></h3>

      

      <p>The default assumption of the server is that Text Files
      (<em>i.e.</em>, all files whose <code>Content-Type:</code>
      starts with <code>text/</code>) are stored in the native
      character set of the host, EBCDIC.</p>

    

    <h3><a name="ssi" id="ssi">Server Side Included Documents</a></h3>

      

      <p>SSI documents must currently be stored in EBCDIC only.
      No provision is made to convert it from ASCII before
      processing.</p>

    <p>La plate-forme Windows de base pour l'exécution d'Apache 2.4 est
    Windows 2000 ou supérieur. Veillez à toujours vous procurer et installer le
    dernier service pack afin d'éviter les bogues du système
    d'exploitation.</p>

    <div class="note">Les versions du serveur HTTP Apache supérieures à 2.2 ne
    fonctionneront sous aucun système d'exploitation d'une version

<h2><a name="down" id="down">Téléchargement d'Apache pour Windows</a></h2>
    

    <p>Le projet du serveur HTTP Apache proprement dit ne fournit pas de
    distribution binaire mais seulement le code source. Certains membres
    du projet <em>peuvent</em> mettre à disposition des paquets binaires
    à titre individuel, mais ceux-ci n'ont pas vocation à être
    distribués publiquement.</p>
    
    <p>Si vous n'êtes
    pas en mesure de compiler le serveur HTTP Apache vous-même, vous
    pouvez vous procurer un paquet binaire auprès des nombreuses
    distributions disponibles sur Internet.</p>

<div class="section">
<h2><a name="cust" id="cust">Personnaliser Apache pour Windows</a></h2>
    

    <p>La configuration d'Apache est enregistrée dans les fichiers du
    sous-répertoire <code>conf</code>. Ce sont les même fichiers que
    ceux utilisés pour configurer la version Unix, mais il y a quelques
    directives spécifiques à Apache pour Windows. Voir l'<a href="../mod/directives.html">index des directives</a> pour la liste
    des directives disponibles.</p>

    <p>Les principales spécificités d'Apache pour Windows sont :</p>
    <ul>
      <li><p>Comme Apache pour Windows est un programme multithread, il
      ne lance pas de processus séparé pour chaque requête, comme Apache
      peut le faire sous Unix. En fait, il n'y a en général que deux
      processus Apache en exécution : un processus parent, et un
      processus enfant qui traite les requêtes. Chaque requête est
      traitée par un thread séparé au sein du processus enfant.</p>

      <p>Les directives de gestion de processus diffèrent également :</p>

      <p><code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code>
      : comme dans la version Unix, cette directive contrôle le nombre
      de connexions qu'un
      processus enfant particulier va traiter avant de s'arrêter.
      Cependant, à la différence d'Unix, un processus de remplacement
      n'est pas instantanément disponible. Utilisez la définition par
      défaut <code>MaxConnectionsPerChild 0</code>, sauf si vous
      risquez de manquer de mémoire dans des modules tiers ou dans des
      applications in-process.</p>

      <div class="warning"><strong>Attention : le fichier de
      configuration du serveur est rechargé lorsqu'un nouveau processus
      enfant est démarré. En conséquence, si vous avez modifié
      <code>httpd.conf</code>, le nouveau processus enfant peut ne pas
      démarrer, ou vous pouvez obtenir des résultats
      inattendus.</strong></div>

      <p><code class="directive"><a href="../mod/mpm_common.html#threadsperchild">ThreadsPerChild</a></code> : il
      s'agit d'une nouvelle directive. Elle indique au serveur le nombre
      de threads qu'il doit utiliser. Elle définit le nombre maximum de
      connexions simultanées que le serveur peut gérer ; vous devez
      donc vous assurer que ce nombre soit suffisamment grand pour les
      besoins de votre site. La valeur par défaut <code>ThreadsPerChild
      150</code> est recommandée, mais doit être ajustée à la valeur
      maximale estimée de connexions simultanées à accepter.</p></li>

      <li><p>Les directives qui acceptent des noms de fichiers comme
      arguments doivent utiliser des noms de fichiers Windows et non
      Unix. Cependant, comme Apache peut interpréter les anti-slashes
      comme des séquences d'échappement de caractères, vous devez
      absolument utiliser des slashes dans les noms de chemins à la
      place des anti-slashes.</p></li>

      <li><p>Alors que les noms de fichiers sont en général insensibles
      à la casse sous Windows, les URLs sont encore sensibles à la casse
      en interne avant d'être mises en correspondance avec le système de
      fichiers. Par exemple, les directives <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>, <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, et <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> utilisent toutes des
      arguments sensibles à la casse. Pour cette raison, il est
      particulièrement recommandé d'utiliser la directive <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> lorsqu'on
      désire limiter l'accès à certains contenus du système de fichiers,
      car cette directive s'applique à tout contenu d'un répertoire,
      sans tenir compte de la manière dont on y accède. Pour vous
      assurer que seules des minuscules sont utilisées dans les URLs,
      vous pouvez utiliser ceci :</p>

      <pre class="prettyprint lang-config">RewriteEngine On
RewriteMap lowercase int:tolower
RewriteCond "%{REQUEST_URI}" "[A-Z]"
RewriteRule "(.*)" "${lowercase:$1}" [R,L]</pre>
</li>

      <li><p>Lors de son exécution, Apache n'a besoin d'un accès en
      écriture qu'au répertoire des journaux et à toute arborescence de
      répertoires de cache configurée. Suite au problème d'insensibilité
      à la casse et au format de noms courts 8.3, Apache doit valider
      tous les noms de chemins fournis. Cela signifie que chaque
      répertoire qu'Apache évalue doit avoir les droits en lecture,
      listage et parcours, et ceci depuis la racine jusqu'aux feuilles.
      Si Apache2.4 est installé dans C:\Program Files, le répertoire
      racine, Program Files et Apache2.4 doivent tous être visibles pour
      Apache</p></li>

      <li><p>Apache peut charger divers modules sans qu'il soit nécessaire
      de recompiler le serveur. Si Apache est compilé
      normalement, il va installer de nombreux modules optionnels dans
      le répertoire <code>\Apache2.4\modules</code>. Pour activer ces
      modules ou d'autres modules, on doit utiliser la
      directive <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code>. Par
      exemple, pour activer le module status, ajoutez la ligne suivante
      (en plus des directives d'activation de status dans
      <code>access.conf</code>) :</p>

      <pre class="prettyprint lang-config">LoadModule status_module "modules/mod_status.so"</pre>


      <p>Des informations sont aussi à votre disposition pour <a href="../mod/mod_so.html#creating">créer des modules
      chargeables</a></p></li>

      <li><p>Apache peut aussi charger des extensions ISAPI (Internet
      Server Application Programming Interface), comme celles qu'utilise
      Microsoft IIS et d'autres serveurs Windows. <a href="../mod/mod_isapi.html">Voir ici pour plus
      d'informations</a>. Notez qu'Apache ne peut <strong>pas</strong>
      charger de filtres ISAPI, et que les gestionnaires ISAPI contenant
      des extensions de fonctionnalités Microsoft ne fonctionneront
      pas.</p></li>

      <li><p>Pour les scripts CGI, la méthode qu'utilise Apache pour
      déterminer l'interpréteur du script est configurable grâce à la
      directive <code class="directive"><a href="../mod/core.html#scriptinterpretersource">ScriptInterpreterSource</a></code></p></li>

      <li><p>Comme il est souvent difficile de gérer des fichiers avec
      des noms du style <code>.htaccess</code> sous Windows, vous avez
      tout intérêt à changer le nom de ce fichier de configuration par
      répertoire à l'aide de la directive <code class="directive"><a href="../mod/core.html#accessfilename">AccessFilename</a></code>.</p></li>

      <li><p>Toute erreur survenant au cours du processus de démarrage
      d'Apache est enregistrée dans le journal des évènements de
      Windows si l'on est sous Windows NT. Ce mécanisme fonctionne comme
      une sauvegarde pour les situations où Apache n'est pas encore prêt
      à utiliser le fichier <code>error.log</code>. Vous pouvez
      consulter le journal des évènements applicatifs Windows en
      utilisant l'observateur d'évènements : Démarrage - Paramètres -
      Panneau de configuration - Outils d'administration - Observateur
      d'évènements.</p></li>

    du réseau. Pour pouvoir gérer un service Apache avec le moniteur,
    vous devez d'abord installer le service (soit automatiquement au
    cours de l'installation, soit manuellement).</p>

    <p>Vous pouvez installer Apache en tant que service Windows NT à
    partir de la ligne de commandes et depuis le sous-répertoire Apache
    <code>bin</code> comme suit :</p>

    <div class="example"><p><code>
      httpd.exe -k install
    </code></p></div>

    <p>Si vous avez installé plusieurs services Apache sur votre
    ordinateur, vous devrez spécifier le nom du service que vous voulez
    installer en utilisant la commande suivante (notez que si vous
    spécifiez un nom durant l'installation, vous devrez aussi le
    spécifier pour toute opération comportant l'option -k) :</p>

    <div class="example"><p><code>
      httpd.exe -k install -n "Nom-service"
    </code></p></div>

    <p>Si un service doit utiliser un fichier de configuration
    spécifique, utilisez ceci :</p>

    <div class="example"><p><code>
      httpd.exe -k install -n "Nom-service" -f "c:\fichiers\Nom-service.conf"
    </code></p></div>

    <p>Si vous utilisez la première commande sans paramètre particulier,
    excepté <code>-k install</code>, le service aura pour nom
    <code>Apache2.4</code> et le fichier de configuration sera censé
    être <code>conf\httpd.conf</code>.</p>

    <p>Supprimer un service Apache est très simple. Utilisez
    simplement :</p>

    <div class="example"><p><code>
      httpd.exe -k uninstall
    </code></p></div>

    <p>On peut spécifier un service Apache particulier en utilisant
    :</p>

    <div class="example"><p><code>
      httpd.exe -k uninstall -n "Nom service"
    </code></p></div>

    <p>Normalement, le démarrage, le redémarrage et l'arrêt d'un
    service Apache s'effectuent via le Moniteur de Service Apache, ou en
    utilisant des commandes telles que <code>NET START Apache2.4</code> et
    <code>NET STOP Apache2.4</code>, ou encore via le gestionnaire de
    services standard de Windows. Avant de démarrer Apache en tant que
    service dans quelque but que ce soit, vous devez tester le fichier
    de configuration du service en utilisant :</p>

    <div class="example"><p><code>
      httpd.exe -n "Nom-service" -t
    </code></p></div>

    <p>Vous pouvez aussi contrôler un service Apache à l'aide de ses
    options de ligne de commande. Avec cette méthode, pour démarrer un
    service Apache installé, vous utiliserez :</p>

    <div class="example"><p><code>
      httpd.exe -k start -n "Nom-Service"
    </code></p></div>

    <p>Pour arrêter un service Apache via les options de lignes de
    commande, utilisez ceci :</p>

    <div class="example"><p><code>
      httpd.exe -k stop -n "Nom-Service"
    </code></p></div>

    <p>ou</p>

    <div class="example"><p><code>
      httpd.exe -k shutdown -n "Nom-Service"
    </code></p></div>

    <p>Vous pouvez aussi redémarrer un service en exécution et le forcer
    à relire son fichier de configuration en utilisant :</p>

    <div class="example"><p><code>
      httpd.exe -k restart -n "Nom-Service"
    </code></p></div>

    <p>Par défaut, tous les services Apache sont configurés pour
    s'exécuter sous l'utilisateur system (le compte
    <code>LocalSystem</code>). Le compte <code>LocalSystem</code> n'a
    pas de privilèges sur votre réseau, que ce soit via un mécanisme
    sécurisé de Windows, y compris le système de fichiers, des tubes
    nommés, DCOM ou des RPC sécurisés. Il a cependant des privilèges
    élevés en local.</p>

    <div class="warning"><strong>N'accordez jamais de privilèges réseau
    au compte <code>LocalSystem</code> ! Si Apache doit pouvoir accéder
    à des ressources réseau, créez un compte séparé pour Apache comme
    indiqué ci-dessous.</strong></div>

    <p>Il est fortement fortement conseillé aux utilisateurs de créer un
    compte séparé pour exécuter le(s) service(s) Apache, et même
    obligatoire si vous devez accéder à des ressources réseau via
    Apache.</p>

    <ol>
      <li>Créez un compte d'utilisateur du domaine normal, et
      assurez-vous de retenir son mot de passe.</li>

      <li>Accordez à l'utilisateur nouvellement créé les privilèges
      <code>Log on as a service</code> et <code>Act as part of the
      operating system</code>. Sous Windows NT 4.0, ces privilèges sont
      accordés via le Gestionnaire des utilisateurs du Domaine, mais
      sous Windows 2000 et XP, vous aurez plutôt intérêt à utiliser une
      GPO pour propager ces configurations. Vous pouvez aussi effectuer
      ces réglages via la Politique de Sécurité Locale intégrée à la
      MMC.</li>

      <li>Vérifiez que le compte nouvellement créé est membre du groupe
      Utilisateurs</li>

      <li>Accordez à ce compte les droits Lecture et Exécution (RX) sur
      tous les documents et répertoires de scripts (<code>htdocs</code>
      et <code>cgi-bin</code> par exemple), et aussi sur l'exécutable
      binaire <code>httpd.exe</code>.</li>

      <li>Accordez aussi à ce compte les droits de modification sur le
      répertoire <code>logs</code>.</li>

    </ol>

    <div class="note">Il est en général de bonne pratique d'accorder à l'utilisateur
    sous lequel le service Apache s'exécute les droits en lecture et
    exécution (RX) sur l'ensemble du répertoire Apache2.4, sauf pour le
    sous-répertoire <code>logs</code>, sur lequel l'utilisateur doit
    avoir au moins les droits de modification (RWXD).</div>

    <p>Si vous permettez à ce compte de se connecter en tant
    qu'utilisateur et service, vous pouvez ouvrir une session sous ce
    compte et vérifier s'il a bien le droit d'exécuter les scripts, de
    lire les pages web, et si vous pouvez démarrer Apache à partir d'une
    console Windows. Si tout fonctionne, et si vous avez suivi les
    étapes ci-dessus, Apache devrait s'exécuter en tant que service sans
    problème.</p>

    <div class="note"><strong>Le code d'erreur 2186</strong> indique probablement
    qu'Apache ne peut pas accéder à une ressource réseau nécessaire, et
    que vous devez revoir la configuration "Log On As" (Se connecter en
    tant que ...) du service.</div>

    <p>Lorsqu'Apache démarre en tant que service, il se peut que vous
    obteniez un message d'erreur du Gestionnaire de Services Windows.
    Par exemple, si vous essayez de démarrer Apache en utilisant
    l'applet Services du Panneau de configuration de Windows, vous
    pouvez obtenir le message suivant :</p>

    <div class="example"><p><code>
      Could not start the Apache2.4 service on \\COMPUTER <br />
      Error 1067; The process terminated unexpectedly.
    </code></p></div>

    <p>Vous obtiendrez cette erreur à caractère général pour tout
    problème survenant au cours du démarrage du service Apache. Afin de
    déterminer exactement la cause du problème, vous devez suivre les
    instructions permettant d'exécuter Apache pour Windows depuis la
    ligne de commande.</p>

    <p>Si vous rencontrez des problèmes avec le service, il est
    conseillé de suivre les instructions ci-dessous afin d'essayer de
    démarrer httpd.exe depuis une console, et d'analyser les erreurs
    plutôt que vous démener à essayer de démarrer le service.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="wincons" id="wincons">Exécuter Apache depuis la console</a></h2>
    

    <p>Il est en général recommandé d'exécuter Apache en tant que
    service, mais il est parfois plus simple d'utiliser la ligne de
    commande, en particulier au cours de la configuration initiale et
    les tests.</p>

    <p>Pour exécuter Apache depuis la ligne de commande et en tant
    qu'application de console, utilisez la commande suivante :</p>

    <div class="example"><p><code>
      httpd.exe
    </code></p></div>

    <p>Apache va démarrer, et continuera son exécution jusqu'à ce qu'on
    l'arrête en tapant Ctrl-C.</p>

    <p>Vous pouvez également démarrer Apache via le raccourci "Démarrer
    Apache dans une console" placé dans <code>Démarrer --&gt;
    Programmes --&gt; Apache HTTP Server 2.4.xx --&gt; Control Apache
    Server</code> au cours de l'installation. Ceci va
    ouvrir une console Windows, et y démarrer Apache.
    Si vous n'avez pas installé Apache en tant que service, la
    fenêtre Windows restera ouverte jusqu'à ce que vous arrêtiez Apache
    en tapant Ctrl-C dans cette fenêtre. Le serveur va alors s'arrêter
    au bout de quelques secondes. Cependant, si vous avez installé
    Apache en tant que service, c'est ce dernier que le raccourci
    ci-dessus va lancer. Si le service Apache est déjà en cours
    d'exécution, le raccourci va rester sans effet.</p>

    <p>Si Apache s'exécute en tant que service, vous pouvez l'arrêter en
    ouvrant une autre console et en entrant :</p>

    <div class="example"><p><code>
      httpd.exe -k shutdown
    </code></p></div>

    <p>Plutôt que de lancer Apache à partir d'une console, il est
    préférable de l'exécuter en tant que service car dans ce cas, il
    termine proprement les opérations en cours avant de s'éteindre.</p>

    <p>Si le serveur a été lancé depuis une console, vous ne pouvez
    l'arrêter qu'en pressant la combinaison de touches Ctrl-C dans la
    même fenêtre.</p>

    <p>Vous pouvez aussi redémarrer Apache. Ceci le force à recharger
    son fichier de configuration. Toute opération en cours peut être
    achevée sans interruption. Pour redémarrer Apache, vous pouvez soit
    taper Control-Break dans la fenêtre de console que vous avez
    utilisée pour le démarrer, soit entrer :</p>

    <div class="example"><p><code>
      httpd.exe -k restart
    </code></p></div>

    <p>si le serveur s'exécute en tant que service.</p>

    <div class="note">Note pour les utilisateurs familiers de la version Unix
    d'Apache : les commandes ci-dessus représentent pour Windows
    l'équivalent des commandes <code>kill -TERM <em>pid</em></code> et
    <code>kill -USR1 <em>pid</em></code>. L'option de ligne de commande
    <code>-k</code> a été choisie à titre de rapprochement avec la
    commande <code>kill</code> utilisée sous Unix.</div>

    <p>Si la fenêtre de la console Apache se ferme immédiatement ou
    inopinément après le démarrage d'Apache, ouvrez une console Windows
    depuis le menu Démarrer --&gt; Programmes. Placez-vous dans le
    répertoire d'installation d'Apache, tapez la commande
    <code>httpd.exe</code>, et observez le message d'erreur. Allez
    ensuite dans le répertoire des journaux, et visualisez le fichier
    <code>error.log</code> pour détecter d'éventuelles erreurs de
    configuration. Si Apache a été installé dans <code>C:\Program
    Files\Apache Software Foundation\Apache2.4\</code>, vous
    pouvez entrer ce qui suit :</p>

    <div class="example"><p><code>
      c: <br />
      cd "\Program Files\Apache Software Foundation\Apache2.4\bin" <br />
      httpd.exe
    </code></p></div>

    <p>Attendez ensuite qu'Apache s'arrête ou tapez Ctrl-C. Entrez alors
    la commande suivante :</p>

    <div class="example"><p><code>
      cd ..\logs <br />
      more &lt; error.log
    </code></p></div>

    <p>Lorsqu'on travaille avec Apache, il est important de comprendre
    comment ce dernier trouve son fichier de configuration. Vous pouvez
    spécifier un fichier de configuration à partir de la ligne de
    commande de deux façons :</p>

    <ul>
      <li><p>L'option <code>-f</code> permet de spécifier un chemin
      absolu ou relatif vers un fichier de configuration particulier
      :</p>(sous Windows 9x, il est recommandé d'utiliser la ligne de
    commande à cause du manque de fiabilité du support des services
    fourni par ce système).

      <div class="example"><p><code>
        httpd.exe -f "c:\fichiers-de-mon-serveur\autre-config.conf"
      </code></p></div>

      <p>ou</p>

      <div class="example"><p><code>
        httpd.exe -f fichiers-de-mon-serveur\autre-config.conf
      </code></p></div></li>

      <li><p>L'option <code>-n</code> permet de spécifier le service
      Apache installé dont le fichier de configuration doit être utilisé
      :</p>

      <div class="example"><p><code>
        httpd.exe -n "Nom-service"
      </code></p></div>
      </li>
    </ul>

    <p>Dans les deux cas, la directive <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> doit être correctement définie
    dans le fichier de configuration.</p>

    <p>Si vous ne spécifiez aucun fichier de configuration à l'aide des
    options <code>-f</code> ou <code>-n</code>, Apache utilisera le nom
    du fichier de configuration compilé dans le serveur, en général
    <code>conf\httpd.conf</code>. Ce chemin codé en dur est relatif au
    répertoire d'installation. Vous pouvez vérifier ce chemin à partir
    de la valeur de l'étiquette <code>SERVER_CONFIG_FILE</code> en
    invoquant Apache avec l'option <code>-V</code>, comme ceci :</p>

    <div class="example"><p><code>
      httpd.exe -V
    </code></p></div>

    <p>Apache va ensuite essayer de déterminer la valeur de son
    <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> en effectuant les
    recherches suivantes, dans cet ordre :</p>

    <ol>
      <li>Une directive <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>
      via l'option de ligne de commande <code>-C</code>.</li>

      <li>L'option de ligne de commande <code>-d</code>.</li>

      <li>Le répertoire de travail courant.</li>

      <li>Une entrée de la base de registre créée dans le cas d'une
      installation binaire.</li>

      <li>La racine des documents (<code>DocumentRoot</code>) codée en dur
      dans le serveur. Elle
      correspond par défaut à <code>/apache</code>, et vous pouvez le
      vérifier en tapant <code>httpd.exe -V</code> et en recherchant
      l'étiquette <code>HTTPD_ROOT</code>.</li>
    </ol>

    <p>Si vous n'avez pas effectué d'installation binaire, dans certains
    scénarios, Apache va signaler l'absence de cette clé de registre.
    On peut passer outre cet avertissement si le serveur a été en mesure
    de trouver son fichier de configuration d'une autre manière.</p>

    <p>La valeur de cette clé correspond au répertoire <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> qui contient lui-même le
    sous-répertoire <code>conf</code>. Lors de son démarrage, Apache lit
    le fichier <code>httpd.conf</code> à partir de ce répertoire. Si ce
    fichier contient une directive <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> qui spécifie un répertoire
    différent de celui que contient la clé de registre ci-dessus, Apache
    oubliera la clé de registre, et utilisera le répertoire spécifié par
    le fichier de configuration. Si vous déplacez le répertoire Apache
    ou ses fichiers de configuration, il est vital de mettre à jour la
    directive <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> dans
    <code>httpd.conf</code> afin de refléter la nouvelle
    localisation.</p>

<div class="section">
<h2><a name="test" id="test">Vérification de l'installation</a></h2>
    

    <p>Une fois Apache démarré (soit à partir d'une console Windows,
    soit en tant que service), ce dernier va se mettre à l'écoute sur
    le port 80 (à moins que vous ayiez modifié la directive <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> dans les fichiers de
    configuration ou que vous ayiez installé Apache pour l'utilisateur
    courant seulement). Pour vous connecter au serveur et accéder à la
    page par défaut, lancez un navigateur et entrez cette URL :</p>

    <div class="example"><p><code>
      http://localhost/
    </code></p></div>

    <p>Apache devrait renvoyer une page de bienvenue et vous devriez
    voir s'afficher "It Works!". Si rien ne se passe ou si vous obtenez
    une erreur, consultez le fichier <code>error.log</code> dans le
    sous-répertoire <code>logs</code>. Si votre serveur n'est pas
    connecté au réseau, ou si vous avez de sérieux problèmes avec la
    configuration de votre DNS (Domain Name Service), vous devez
    utiliser cette URL :</p>

    <div class="example"><p><code>
      http://127.0.0.1/
    </code></p></div>

    <p>Si Apache écoute un port non standard, vous devez le préciser
    explicitement dans l'URL :</p>

    <div class="example"><p><code>
      http://127.0.0.1:8080/
    </code></p></div>

    <p>Après que votre installation de base fonctionne, vous devez la
    configurer correctement en éditant les fichiers du sous-répertoire
    <code>conf</code>. Encore une fois, si vous modifiez la
    configuration du service Apache sous Windows NT, essayez d'abord de
    redémarrer le service depuis la ligne de commande afin de vous
    assurer de l'absence d'erreur.</p>

    <p>Comme Apache <strong>ne peut pas</strong> partager le même port
    avec d'autres applications TCP/IP, il se peut que vous soyez amené à
    arrêter, désinstaller ou reconfigurer certains services avant de
    démarrer Apache. Ces services entrant en conflit avec Apache
    comprennent les autres serveurs WWW, certaines implémentations de
    pare-feu, et même certaines applications client (comme Skype) qui
    utilisent le port 80 afin de contourner les pare-feu.</p>

<h2><a name="windrivemap" id="windrivemap">Configuration de l'accès aux ressources réseau</a></h2>
    

  <p>L'accès à des fichiers par le réseau peut être spécifié via deux
  mécanismes fournis par Windows :</p>

  <dl>
    <dt>Association de lettres de lecteur</dt>
    <dd>Par exemple, <code>Alias "/images/" "Z:/"</code></dd>

    <dt>chemins UNC</dt>
    <dd>Par exemple, <code>Alias "/images/" "//imagehost/www/images/"</code></dd>
  </dl>

  <p>L'association de lettres de lecteur permet à l'administrateur de
  maintenir une correspondance avec une certaine machine et un certain
  chemin en dehors de la configuration d'Apache httpd. Cependant, ces
  associations ne sont possibles que dans le cadre des sessions
  interactives, et ne sont pas directement disponibles pour Apache httpd
  lorsqu'il est démarré en tant que service. <strong>N'utilisez par
  conséquent que des
  chemins UNC pour les ressources réseau dans httpd.conf,</strong> de
  façon à ce que les ressources soient accessibles quelle que soit la
  manière dont Apache httpd a été démarré (des procédures exotiques et
  probablement sujettes aux erreurs peuvent permettre de contourner la
  restriction due aux associations de lettres de lecteur, mais leur
  utilisation est déconseillée).</p>

  <div class="example"><h3>Exemple de DocumentRoot avec chemin UNC</h3><pre class="prettyprint lang-config">DocumentRoot "//dochost/www/html/"</pre>

    <p>Alors que de nombreuses distributions mettent à disposition des
    paquets Apache httpd supportés par le système d'exploitation
    sous-jacent, il peut s'avérer nécessaire d'installer et d'utiliser
    la version de base d'Apache httpd en remplacement de la version des
    paquets.</p>

    <p>Bien que le projet Apache httpd ne crée pas actuellement de
    paquets RPM pour les différentes distributions, il est aisé de
    construire votre propre paquet RPM à partir du tarball de base
    d'Apache httpd.</p>

    <p>Ce document explique comment construire, installer, configurer et
    exécuter Apache httpd 2.4 sur les systèmes Unix à base de paquets
    RPM.</p>

    <p>Le tarball d'Apache httpd peut être converti en paquet SRPM de la

    <p>Il sera nécessaire d'installer les paquets "-devel"

    commande <code>rpmbuild</code> détecte automatiquement les RPMs
    requis et en donne la liste sous forme de dépendances manquantes sur
    votre système. Ces paquets "-devel" ne seront d'ailleurs plus
    nécessaires une fois la création des RPMs terminée, et pourront
    alors être supprimés sans risque.</p>

<h2><a name="installing" id="installing">Installation du serveur</a></h2>
    

    <p>Le RPM <code>httpd</code> est le seul paquet nécessaire pour
    obtenir un serveur de base fonctionnel. Vous pouvez l'installer
    comme suit :</p>

    <div class="example"><p><code>
      rpm -U httpd-2.4.x-1.i686.rpm
    </code></p></div>

    <p>Le jeu de modules standards est inclus dans le serveur. Les
    modules qui dépendent de bibliothèques externes sont fournis en tant
    que paquets RPM séparés et doivent être installés si nécessaire.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="default" id="default">Configuration de l'instance par défaut d'Apache httpd</a></h2>
    

    <p>Les répertoires par défaut sont
    <code>/etc/httpd</code> pour la configuration du serveur, et
    <code>/var/log/httpd</code> pour la journalisation. L'environnement
    par défaut du serveur web est défini dans le répertoire optionnel
    <code>/etc/sysconfig/httpd</code>.</p>

    <p>Démarrez le serveur comme suit :</p>

    <div class="example"><p><code>
      service httpd restart
    </code></p></div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="additional" id="additional">Configuration d'instances d'Apache httpd supplémentaires sur
    la même machine</a></h2>
    

    <p>Il est possible d'exécuter simultanément plusieurs instances du
    serveur Apache httpd sur la même machine. Chaque instance peut
    posséder sa propre configuration et en fonction de cette dernière,
    s'exécuter sous un utilisateur différent.</p>

    <p>Pour parvenir à ce résultat, on a fait en sorte que le script de
    démarrage de httpd ait connaissance de son propre nom. Ce nom est
    par la suite utilisé pour trouver le fichier d'environnement associé
    au serveur, et par conséquent, la racine de l'instance du serveur
    considéré.</p>

    <p>Pour créer une instance supplémentaire appelée
    <code>httpd-additional</code>, suivez ces étapes :</p>

    <ul>
      <li>Créez un lien symbolique vers le script de démarrage pour
      l'instance supplémentaire :

      <div class="example"><p><code>
        ln -s /etc/rc.d/init.d/httpd /etc/rc.d/init.d/httpd-additional<br />
        chkconfig --add httpd-additional
      </code></p></div>

      </li>

      <li>Créez un fichier d'environnement pour l'instance
      supplémentaire, en utilisant le fichier
      <code>/etc/sysconfig/httpd</code> comme modèle :

      <div class="example"><p><code>
        # création du fichier d'environnement à partir du modèle httpd<br />
        cp /etc/sysconfig/httpd /etc/sysconfig/httpd-additional
      </code></p></div>
      
      <div class="example"><p><code>
        # création du fichier d'environnement à partir de zéro<br />
        touch /etc/sysconfig/httpd-additional
      </code></p></div>

      Editez le fichier <code>/etc/sysconfig/httpd-additional</code> et
      définissez la racine de la nouvelle instance du serveur via la
      variable d'environnement <code>OPTIONS</code>.

      <div class="example"><p><code>
        OPTIONS="-d /etc/httpd-additional -f conf/httpd-additional.conf"
      </code></p></div>

      </li>

      <li>Editez le fichier de configuration du serveur supplémentaire
      <code>/etc/httpd-additional/conf/httpd-additional.conf</code> et
      assurez-vous que les ports et chemins sont correctement définis.
      </li>

      <li>Démarrez le serveur supplémentaire comme suit :

      <div class="example"><p><code>
        service httpd-additional restart
      </code></p></div>

      </li>

      <li>Répétez ces opérations pour chaque instance supplémentaire
      souhaitée.</li>
    </ul>

    <p>There are many important points to consider before you begin compiling
    Apache HTTP Server (httpd). See <a href="windows.html">Using Apache HTTP
    Server on Microsoft Windows</a> before you begin.</p>

    <p>httpd can be built on Windows using a cmake-based build system or with
    Visual Studio project files maintained by httpd developers.  The cmake-based
    build system directly supports more versions of Visual Studio but currently
    has considerable functional limitations.</p>

  <h3><a name="requirements" id="requirements">Requirements</a></h3>

    

    <p>Compiling Apache requires the following environment to be
    properly installed:</p>

    <ul>
      <li>
        <p>Disk Space</p>

        <p>Make sure you have at least 200 MB of free disk space
        available. After installation Apache requires approximately
        80 MB of disk space, plus space for log and cache files,
        which can grow rapidly. The actual disk space requirements
        will vary considerably based on your chosen configuration and
        any third-party modules or libraries, especially when OpenSSL
        is also built.  Because many files are text and very easily
        compressed, NTFS filesystem compression cuts these requirements
        in half.</p>
      </li>

      <li>
        <p>Appropriate Patches</p>

        <p>The httpd binary is built with the help of several patches to
        third party packages, which ensure the released code is buildable
        and debuggable.  These patches are available and distributed from <a href="http://www.apache.org/dist/httpd/binaries/win32/patches_applied/">http://www.apache.org/dist/httpd/binaries/win32/patches_applied/</a>
        and are recommended to be applied to obtain identical results as the
        "official" ASF distributed binaries.</p>
      </li>

      <li>
        <p>Microsoft Visual C++ 6.0 (Visual Studio 97) or later.</p>

        <p>Apache can be built using the command line tools, or from
        within the Visual Studio IDE Workbench.  The command line
        build requires the environment to reflect the <code>PATH</code>,
        <code>INCLUDE</code>, <code>LIB</code> and other variables
        that can be configured with the <code>vcvars32.bat</code> script.</p>

        <div class="note">You may want the Visual Studio Processor Pack for your older
        version of Visual Studio, or a full (not Express) version of newer
        Visual Studio editions, for the ml.exe assembler.  This will allow
        you to build OpenSSL, if desired, using the more efficient assembly
        code implementation.</div>

        <div class="note">Only the Microsoft compiler tool chain is actively supported by
        the active httpd contributors.  Although the project regularly accepts
        patches to ensure MinGW and other alternative builds work and improve
        upon them, they are not actively maintained and are often broken in
        the course of normal development.</div>
      </li>

      <li>
        <p>Updated Microsoft Windows Platform SDK, February 2003 or later.</p>

        <p>An appropriate Windows Platform SDK is included by default in the
        full (not express/lite) versions  of Visual C++ 7.1 (Visual Studio 2002)
        and later, these users can ignore these steps unless explicitly choosing
        a newer or different version of the Platform SDK.</p>

        <p>To use Visual C++ 6.0 or 7.0 (Studio 2000 .NET), the Platform SDK
        environment must be prepared using the <code>setenv.bat</code>
        script (installed by the Platform SDK) before starting the command
        line build or launching the msdev/devenv GUI environment.  Installing
        the Platform SDK for Visual Studio Express versions (2003 and later)
        should adjust the default environment appropriately.</p>

        <div class="example"><p><code>
          "c:\Program Files\Microsoft Visual Studio\VC98\Bin\VCVARS32"<br />
          "c:\Program Files\Platform SDK\setenv.bat"
        </code></p></div>
      </li>

      <li>
        <p>Perl and awk</p>

        <p>Several steps recommended here require a perl interpreter during
        the build preparation process, but it is otherwise not required.</p>

        <p>To install Apache within the build system, several files are
        modified using the <code>awk.exe</code> utility. awk was chosen since
        it is a very small download (compared with Perl or WSH/VB) and
        accomplishes the task of modifying configuration files upon
        installation.  Brian Kernighan's
        <a href="http://www.cs.princeton.edu/~bwk/btl.mirror/">http://www.cs.princeton.edu/~bwk/btl.mirror/</a>
        site has a compiled native Win32 binary,
        <a href="http://www.cs.princeton.edu/~bwk/btl.mirror/awk95.exe">http://www.cs.princeton.edu/~bwk/btl.mirror/awk95.exe</a> which
        you must save with the name <code>awk.exe</code> (rather than
        <code>awk95.exe</code>).</p>

        <div class="note">If awk.exe is not found, Makefile.win's install target
        will not perform substitutions in the installed .conf files.
        You must manually modify the installed .conf files to allow
        the server to start.  Search and replace all "@token@" tags
        as appropriate.</div>

        <div class="note">The Visual Studio IDE will only find <code>awk.exe</code>
        from the PATH, or executable path specified in the menu option
        Tools -&gt; Options -&gt; (Projects -&gt;) Directories.  Ensure
        awk.exe is in your system path.</div>

        <div class="note">Also note that if you are using Cygwin tools
        (<a href="http://www.cygwin.com/">http://www.cygwin.com/</a>)
        the awk utility is named <code>gawk.exe</code> and that the file
        <code>awk.exe</code> is really a symlink to the <code>gawk.exe</code>
        file. The Windows command shell does not recognize symlinks, and
        because of this building InstallBin will fail. A workaround is
        to delete <code>awk.exe</code> from the cygwin installation and
        copy <code>gawk.exe</code> to <code>awk.exe</code>.  Also note the
        cygwin/mingw ports of gawk 3.0.x were buggy, please upgrade to 3.1.x
        before attempting to use any gawk port.</div>
      </li>

      <li>
        <p>[Optional] zlib library (for <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code>)</p>

        <p>Zlib must be installed into a <code>srclib</code> subdirectory named
        <code>zlib</code>.  This must be built in-place.  Zlib can be obtained
        from <a href="http://www.zlib.net/">http://www.zlib.net/</a> -- the
        <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code> is confirmed to work correctly with
        version 1.2.3.</p>

        <div class="example"><p><code>
          nmake -f win32\Makefile.msc<br />
          nmake -f win32\Makefile.msc test
        </code></p></div>
      </li>

      <li>
        <p>[Optional] OpenSSL libraries (for <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>
        and <code>ab.exe</code> with ssl support)</p>

        <div class="note">The OpenSSL library is cryptographic software.  The country
        in which you currently reside may have restrictions on the import,
        possession, use, and/or re-export to another country, of encryption
        software.  BEFORE using any encryption software, please check your
        country's laws, regulations and policies concerning the import,
        possession, or use, and re-export of encryption software, to see
        if this is permitted.  See
        <a href="http://www.wassenaar.org/">http://www.wassenaar.org/</a>
        for more information.</div>

        <p>Configuring and building OpenSSL requires perl to be installed.</p>

        <p>OpenSSL must be installed into a <code>srclib</code> subdirectory
        named <code>openssl</code>, obtained from
        <a href="http://www.openssl.org/source/">http://www.openssl.org/source/</a>, in order to compile
        <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> or the <code>abs.exe</code> project, which
        is ab.c with SSL support enabled.  To prepare OpenSSL to be linked
        to Apache mod_ssl or abs.exe, and disable patent encumbered features
        in OpenSSL,  you might use the following build commands:</p>

        <div class="example"><p><code>
          perl Configure no-rc5 no-idea enable-mdc2 enable-zlib VC-WIN32
               -Ipath/to/srclib/zlib -Lpath/to/srclib/zlib<br />
          ms\do_masm.bat<br />
          nmake -f ms\ntdll.mak
        </code></p></div>

        <div class="note">It is not advisable to use zlib-dynamic, as that transfers
        the cost of deflating SSL streams to the first request which must
        load the zlib dll.  Note the suggested patch enables the -L flag to
        work with windows builds, corrects the name of zdll.lib and ensures
        .pdb files are generated for troubleshooting.  If the assembler is
        not installed, you would add no-asm above and use ms\do_ms.bat
        instead of the ms\do_masm.bat script.</div>
      </li>

      <li>
        <p>[Optional] Database libraries (for <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code>
        and <code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>)</p>

        <p>The apr-util library exposes dbm (keyed database) and dbd (query
        oriented database) client functionality to the httpd server and its
        modules, such as authentication and authorization.  The sdbm dbm and
        odbc dbd providers are compiled unconditionally.</p>

        <p>The dbd support includes the Oracle instantclient package, MySQL,
        PostgreSQL and sqlite.  To build these all, for example, set up the
        LIB to include the library path, INCLUDE to include the headers path,
        and PATH to include the dll bin path of all four SDK's, and set the
        DBD_LIST environment variable to inform the build which client driver
        SDKs are installed correctly, e.g.;</p>

        <div class="example"><p><code>
          set DBD_LIST=sqlite3 pgsql oracle mysql
        </code></p></div>

        <p>Similarly, the dbm support can be extended with DBM_LIST to
        build a Berkeley DB provider (db) and/or gdbm provider, by similarly
        configuring LIB, INCLUDE and PATH first to ensure the client library
        libs and headers are available.</p>

        <div class="example"><p><code>
          set DBM_LIST=db gdbm
        </code></p></div>

        <div class="note">Depending on the choice of database distributions, it may be
        necessary to change the actual link target name (e.g. gdbm.lib vs.
        libgdb.lib) that are listed in the corresponding .dsp/.mak files
        within the directories srclib\apr-util\dbd or ...\dbm.</div>

        <p>See the README-win32.txt file for more hints on obtaining the
        various database driver SDKs.</p>
      </li>
    </ul>

  

  <h3><a name="unixsrcbuild" id="unixsrcbuild">Building from Unix sources</a></h3>

    

    <p>The policy of the Apache HTTP Server project is to only release Unix sources.
    Windows source packages made available for download have been supplied by 
    volunteers and may not be available for every release. You can still build 
    the server on Windows from the Unix source tarball with just a few additional
    steps.</p>

    <ol>
    	<li>Download and unpack the Unix source tarball for the latest version.</li>
    	<li>Download and unpack the Unix source tarball for latest version of
        APR, AR-Util and APR-Iconv, place these sources in directories  httpd-2.x.x\srclib\apr, httpd-2.x.x\srclib\apr-util and httpd-2.x.x\srclib\apr-iconv</li>
    	<li>Open a Command Prompt and CD to the httpd-2.x.x folder</li>
    	<li>Run the line endings conversion utility at the prompt;</li>
    </ol>

    <div class="example"><p><code>
      perl srclib\apr\build\lineends.pl
    </code></p></div>

    <p>You can now build the server with the Visual Studio development 
    environment using the IDE. Command-Line builds of the server are not 
    possible from Unix sources unless you export .mak files as explained 
    below.
    </p>

  

  <h3><a name="commandbuild" id="commandbuild">Command-Line Build</a></h3>

    

    <p><code>Makefile.win</code> is the top level Apache makefile.
    To compile Apache on Windows, simply use one of the following commands
    to build the <code>release</code> or <code>debug</code> flavor:</p>

    <div class="example"><p><code>
      nmake /f Makefile.win _apacher<br /><br />
      nmake /f Makefile.win _apached
    </code></p></div>

    <p>Either command will compile Apache. The latter will disable
    optimization of the resulting files, making it easier to single
    step the code to find bugs and track down problems.</p>

    <p>You can add your apr-util dbd and dbm provider choices with the
    additional make (environment) variables DBD_LIST and DBM_LIST,
    see the comments about [Optional] Database libraries, above.
    Review the initial comments in Makefile.win for additional options
    that can be provided when invoking the build.</p>

  

  <h3><a name="workspacebuild" id="workspacebuild">Developer Studio Workspace IDE Build</a></h3>

    

    <p>Apache can also be compiled using VC++'s Visual Studio
    development environment. To simplify this process, a
    Visual Studio workspace, <code>Apache.dsw</code>, is provided.
    This workspace exposes the entire list of working <code>.dsp</code>
    projects that are required for the complete Apache binary release.
    It includes dependencies between the projects to assure that they
    are built in the appropriate order.</p>

    <p>Open the <code>Apache.dsw</code> workspace, and select
    <code>InstallBin</code> (<code>Release</code> or <code>Debug</code> build,
    as desired) as the Active Project. <code>InstallBin</code> causes all
    related project to be built, and then invokes <code>Makefile.win</code> to
    move the compiled executables and dlls. You may personalize the
    <code>INSTDIR=</code> choice by changing <code>InstallBin</code>'s Settings,
    General tab, Build command line entry. <code>INSTDIR</code> defaults to the
    <code>/Apache2</code> directory. If you only want a test compile (without
    installing) you may build the <code>BuildBin</code> project instead.</p>

    <p>The <code>.dsp</code> project files are distributed in Visual Studio 6.0
    (98) format. Visual C++ 5.0 (97) will recognize them. Visual Studio
    2002 (.NET) and later users must convert <code>Apache.dsw</code> plus
    the <code>.dsp</code> files into an <code>Apache.sln</code> plus
    <code>.msproj</code> files.  Be sure you reconvert the <code>.msproj</code>
    file again if its source <code>.dsp</code> file changes! This is really
    trivial, just open <code>Apache.dsw</code> in the VC++ 7.0 IDE once again
    and reconvert.</p>

    <div class="note">There is a flaw in the .vcproj conversion of .dsp files.  devenv.exe
    will mis-parse the /D flag for RC flags containing long quoted /D'efines
    which contain spaces.  The command:
    <div class="example"><p><code>
      perl srclib\apr\build\cvtdsp.pl -2005
    </code></p></div>
    will convert the /D flags for RC flags to use an alternate, parseable
    syntax; unfortunately this syntax isn't supported by Visual Studio 97
    or its exported .mak files.  These /D flags are used to pass the long
    description of the mod_apachemodule.so files to the shared .rc resource
    version-identifier build.</div>

	<div class="note"><strong>Building with OpenSSL 1.1.0 and up</strong>
    Due to difference in the build structure of OpenSSL begining with version
    1.1.0 you will need to convert the dsp files affected with cvtdsp.pl from
    APR 1.6 or greater.  The command:
    <div class="example"><p><code>
      perl srclib\apr\build\cvtdsp.pl -ossl11
    </code></p></div>
	</div>

    <p>Visual Studio 2002 (.NET) and later users should also use the Build
    menu, Configuration Manager dialog to uncheck both the <code>Debug</code>
    and <code>Release</code> Solution modules <code>abs</code>,
    <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code> and <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> components, as
    well as every component starting with <code>apr_db*</code>.  These modules
    are built by invoking <code>nmake</code>, or the IDE directly with the
    <code>BinBuild</code> target, which builds those modules conditionally
    if the <code>srclib</code> directories <code>openssl</code> and/or
    <code>zlib</code> exist, and based on the setting of <code>DBD_LIST</code>
    and <code>DBM_LIST</code> environment variables.</p>

  

  <h3><a name="exportingmakfiles" id="exportingmakfiles">Exporting command-line .mak files</a></h3>

    

    <p>Exported <code>.mak</code> files pose a greater hassle, but they are
    required for Visual C++ 5.0 users to build <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>,
    abs (<code class="program"><a href="../programs/ab.html">ab</a></code> with SSL support) and/or
    <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code>.  The .mak files also support a broader
    range of C++ tool chain distributions, such as Visual Studio Express.</p>

    <p>You must first build all projects in order to create all dynamic
    auto-generated targets, so that dependencies can be parsed correctly.
    Build the entire project from within the Visual Studio 6.0 (98) IDE,
    using the <code>BuildAll</code> target, then use the Project Menu Export
    for all makefiles (checking on "with dependencies".)  Run the following
    command to correct absolute paths into relative paths so they will build
    anywhere:</p>

    <div class="example"><p><code>
      perl srclib\apr\build\fixwin32mak.pl
    </code></p></div>

    <p>You must type this command from the <em>top level</em>
    directory of the httpd source tree. Every
    <code>.mak</code> and <code>.dep</code> project file within
    the current directory and below will be corrected, and the
    timestamps adjusted to reflect the <code>.dsp</code>.</p>

    <p>Always review the generated <code>.mak</code> and <code>.dep</code>
    files for Platform SDK or other local, machine specific file paths.
    The <code>DevStudio\Common\MSDev98\bin\</code> (VC6) directory contains
    a <code>sysincl.dat</code> file, which lists all exceptions.  Update
    this file (including both forward and backslashed paths, such as both
    <code>sys/time.h</code> and <code>sys\time.h</code>) to ignore such
    newer dependencies.  Including local-install paths in a distributed
    <code>.mak</code> file will cause the build to fail completely.</p>

    <p>If you contribute back a patch that revises project files, we
    must commit project files in Visual Studio 6.0 format. Changes
    should be simple, with minimal compilation and linkage flags that
    can be recognized by all Visual Studio environments.</p>

  

  <h3><a name="installation" id="installation">Installation</a></h3>

    

    <p>Once Apache has been compiled, it needs to be installed in
    its server root directory. The default is the
    <code>\Apache2</code> directory, of the same drive.</p>

    <p>To build and install all the files into the desired folder
    <em>dir</em> automatically, use one of the following
    <code>nmake</code> commands:</p>

    <div class="example"><p><code>
      nmake /f Makefile.win installr INSTDIR=<em>dir</em><br />
      nmake /f Makefile.win installd INSTDIR=<em>dir</em>
    </code></p></div>

    <p>The <em>dir</em> argument to <code>INSTDIR</code> provides
    the installation directory; it can be omitted if Apache is
    to be installed into <code>\Apache22</code> (of the current
    drive).</p>

  

  <h3><a name="projectcomponents-warn" id="projectcomponents-warn">Warning about building Apache from the development tree</a></h3>

    

    <div class="note">Note only the <code>.dsp</code> files are maintained between <code>release</code>
    builds. The <code>.mak</code> files are NOT regenerated, due to the tremendous
    waste of reviewer's time. Therefore, you cannot rely on the <code>NMAKE</code>
    commands above to build revised <code>.dsp</code> project files unless you
    then export all <code>.mak</code> files yourself from the project. This is
    unnecessary if you build from within the Microsoft
    Developer Studio environment.</div>

<h2><a name="cmake" id="cmake">Building httpd with cmake</a></h2>
  

  <p>The primary documentation for this build mechanism is in the 
  <code>README.cmake</code> file in the source distribution.  Refer to that file
  for detailed instructions.</p>

  <p>Building httpd with cmake requires building APR and APR-util separately.
  Refer to their <code>README.cmake</code> files for instructions.</p>

  <p>The primary limitations of the cmake-based build are inherited from the APR-util
  project, and are listed below because of their impact on httpd:</p>

  <ul>
    <li>No cmake build for the APR-iconv subproject is available, and the
      APR-util cmake build cannot consume an existing APR-iconv build.  Thus,
      <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> and possibly some third-party modules 
      cannot be used.</li>
    <li>The cmake build for the APR-util subproject does not support most of the
      optional DBM and DBD libraries supported by the included Visual Studio
      project files.  This limits the database backends supported by a number of
      bundled and third-party modules.</li>

    <p>This document explains how to install, configure and run
    Apache 2.4 under Microsoft Windows.  If you have questions after
    reviewing the documentation (and any event and error logs), you
    should consult the peer-supported
    <a href="http://httpd.apache.org/userslist.html">users' mailing
    list</a>.</p>

    <p>This document assumes that you are installing a binary
    distribution of Apache. If you want to compile Apache yourself
    (possibly to help with development or tracking down bugs),
    see <a href="win_compiling.html">Compiling Apache for Microsoft
    Windows</a>.</p>

    <p>The Apache HTTP Server Project itself does not provide binary releases of
    software, only source code. Individual committers <em>may</em> provide
    binary packages as a convenience, but it is not a release deliverable.</p>
    <p>If you cannot compile the Apache HTTP Server
    yourself, you can obtain a binary package from numerous binary distributions
    available on the Internet.</p>

<h2><a name="cust" id="cust">Customizing Apache for Windows</a></h2>
    

    <p>Apache is configured by the files in the <code>conf</code>
    subdirectory. These are the same files used to configure the Unix
    version, but there are a few different directives for Apache on
    Windows. See the <a href="../mod/directives.html">directive index</a>
    for all the available directives.</p>

    <p>The main differences in Apache for Windows are:</p>
    <ul>
      <li><p>Because Apache for Windows is multithreaded, it does not
      use a separate process for each request, as Apache can on Unix.
      Instead there are usually only two Apache processes running: a
      parent process, and a child which handles the requests. Within
      the child process each request is handled by a separate thread.
      </p>

      <p>The process management directives are also different:</p>

      <p><code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code>:
      Like the Unix directive, this controls how many connections a single
      child process will serve before exiting.
      However, unlike on Unix, a replacement process is not instantly
      available.  Use the default <code>MaxConnectionsPerChild 0</code>,
      unless instructed to change the behavior to overcome a memory leak
      in third party modules or in-process applications.</p>

      <div class="warning"><strong>Warning: The server configuration
      file is reread when a new child process is started. If you have
      modified <code>httpd.conf</code>, the new child may not start or
      you may receive unexpected results.</strong></div>

      <p><code class="directive"><a href="../mod/mpm_common.html#threadsperchild">ThreadsPerChild</a></code>:
      This directive is new. It tells the server how many threads it
      should use. This is the maximum number of connections the server
      can handle at once, so be sure to set this number high enough for
      your site if you get a lot of hits. The recommended default is
      <code>ThreadsPerChild 150</code>, but this must be adjusted to
      reflect the greatest anticipated number of simultaneous
      connections to accept.</p></li>

      <li><p>The directives that accept filenames as arguments must use
      Windows filenames instead of Unix ones. However, because Apache
      may interpret backslashes as an "escape character" sequence, you
      should consistently use forward slashes in path names, not
      backslashes.</p></li>

      <li><p>While filenames are generally case-insensitive on
      Windows, URLs are still treated internally as case-sensitive
      before they are mapped to the filesystem.  For example, the
      <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>,
      <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, and <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> directives all use
      case-sensitive arguments.  For this reason, it is particularly
      important to use the <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> directive when attempting
      to limit access to content in the filesystem, since this
      directive applies to any content in a directory, regardless of
      how it is accessed.  If you wish to assure that only lowercase
      is used in URLs, you can use something like:</p>

      <pre class="prettyprint lang-config">RewriteEngine On
RewriteMap lowercase int:tolower
RewriteCond "%{REQUEST_URI}" "[A-Z]"
RewriteRule "(.*)" "${lowercase:$1}" [R,L]</pre>
</li>

      <li><p>When running, Apache needs write access only to the logs
      directory and any configured cache directory tree.  Due to the
      issue of case insensitive and short 8.3 format names, Apache must
      validate all path names given.  This means that each directory
      which Apache evaluates, from the drive root up to the directory
      leaf, must have read, list and traverse directory permissions.
      If Apache2.4 is installed at C:\Program Files, then the root
      directory, Program Files and Apache2.4 must all be visible
      to Apache.</p></li>

      <li><p>Apache for Windows contains the ability to load modules at
      runtime, without recompiling the server. If Apache is compiled
      normally, it will install a number of optional modules in the
      <code>\Apache2.4\modules</code> directory. To activate these or
      other modules, the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code>
      directive must be used. For example, to activate the status
      module, use the following (in addition to the status-activating
      directives in <code>access.conf</code>):</p>

      <pre class="prettyprint lang-config">LoadModule status_module "modules/mod_status.so"</pre>


      <p>Information on <a href="../mod/mod_so.html#creating">creating
      loadable modules</a> is also available.</p></li>

      <li><p>Apache can also load ISAPI (Internet Server Application
      Programming Interface) extensions such as those used by Microsoft
      IIS and other Windows servers. <a href="../mod/mod_isapi.html">More
      information is available</a>. Note that Apache <strong>cannot</strong>
      load ISAPI Filters, and ISAPI Handlers with some Microsoft feature
      extensions will not work.</p></li>

      <li><p>When running CGI scripts, the method Apache uses to find
      the interpreter for the script is configurable using the
      <code class="directive"><a href="../mod/core.html#scriptinterpretersource">ScriptInterpreterSource</a></code>
      directive.</p></li>

      <li><p>Since it is often difficult to manage files with names
      like <code>.htaccess</code> in Windows, you may find it useful to
      change the name of this per-directory configuration file using
      the <code class="directive"><a href="../mod/core.html#accessfilename">AccessFilename</a></code>
      directive.</p></li>

      <li><p>Any errors during Apache startup are logged into the
      Windows event log when running on Windows NT. This mechanism
      acts as a backup for those situations where Apache is not yet
      prepared to use the <code>error.log</code> file. You can
      review the Windows Application Event Log by using the Event Viewer,
      e.g. Start - Settings - Control Panel - Administrative Tools
      - Event Viewer.</p></li>

<h2><a name="winsvc" id="winsvc">Running Apache as a Service</a></h2>
    

    <p>Apache comes with a utility called the Apache Service Monitor.
    With it you can see and manage the state of all installed Apache
    services on any machine on your network. To be able to manage an
    Apache service with the monitor, you have to first install the
    service (either automatically via the installation or manually).
    </p>

    <p>You can install Apache as a Windows NT service as follows from
    the command prompt at the Apache <code>bin</code> subdirectory:</p>

    <div class="example"><p><code>
      httpd.exe -k install
    </code></p></div>

    <p>If you need to specify the name of the service you want to
    install, use the following command. You have to do this if you
    have several different service installations of Apache on your
    computer. If you specify a name during the install, you have to
    also specify it during any other -k operation.</p>

    <div class="example"><p><code>
      httpd.exe -k install -n "MyServiceName"
    </code></p></div>

    <p>If you need to have specifically named configuration files for
    different services, you must use this:</p>

    <div class="example"><p><code>
      httpd.exe -k install -n "MyServiceName" -f "c:\files\my.conf"
    </code></p></div>

    <p>If you use the first command without any special parameters except
    <code>-k install</code>, the service will be called <code>Apache2.4</code>
    and the configuration will be assumed to be <code>conf\httpd.conf</code>.
    </p>

    <p>Removing an Apache service is easy. Just use:</p>

    <div class="example"><p><code>
      httpd.exe -k uninstall
    </code></p></div>

    <p>The specific Apache service to be uninstalled can be specified by using:</p>

    <div class="example"><p><code>
      httpd.exe -k uninstall -n "MyServiceName"
    </code></p></div>

    <p>Normal starting, restarting and shutting down of an Apache
    service is usually done via the Apache Service Monitor, by using
    commands like <code>NET START Apache2.4</code> and <code>NET STOP
    Apache2.4</code> or via normal Windows service management. Before
    starting Apache as a service by any means, you should test the
    service's configuration file by using:</p>

    <div class="example"><p><code>
      httpd.exe -n "MyServiceName" -t
    </code></p></div>

    <p>You can control an Apache service by its command line switches,
    too. To start an installed Apache service you'll use this:</p>

    <div class="example"><p><code>
      httpd.exe -k start -n "MyServiceName"
    </code></p></div>

    <p>To stop an Apache service via the command line switches, use
    this:</p>

    <div class="example"><p><code>
      httpd.exe -k stop -n "MyServiceName"
    </code></p></div>

    <p>or</p>

    <div class="example"><p><code>
      httpd.exe -k shutdown -n "MyServiceName"
    </code></p></div>

    <p>You can also restart a running service and force it to reread
    its configuration file by using:</p>

    <div class="example"><p><code>
      httpd.exe -k restart -n "MyServiceName"
    </code></p></div>

    <p>By default, all Apache services are registered to run as the
    system user (the <code>LocalSystem</code> account). The
    <code>LocalSystem</code> account has no privileges to your network
    via any Windows-secured mechanism, including the file system, named
    pipes, DCOM, or secure RPC. It has, however, wide privileges locally.
    </p>

    <div class="warning"><strong>Never grant any network privileges to
    the <code>LocalSystem</code> account! If you need Apache to be able
    to access network resources, create a separate account for Apache as
    noted below.</strong></div>

    <p>It is recommended that users create a separate account for running
    Apache service(s). If you have to access network resources via Apache,
    this is required.</p>

    <ol>
      <li>Create a normal domain user account, and be sure to
      memorize its password.</li>

      <li>Grant the newly-created user a privilege of <code>Log on
      as a service</code> and <code>Act as part of the operating
      system</code>. On Windows NT 4.0 these privileges are granted via
      User Manager for Domains, but on Windows 2000 and XP you probably
      want to use Group Policy for propagating these settings. You can
      also manually set these via the Local Security Policy MMC snap-in.
      </li>

      <li>Confirm that the created account is a member of the Users
      group.</li>

      <li>Grant the account read and execute (RX) rights to all document
      and script folders (<code>htdocs</code> and <code>cgi-bin</code>
      for example).</li>

      <li>Grant the account change (RWXD) rights to the
      Apache <code>logs</code> directory.</li>

      <li>Grant the account read and execute (RX) rights to the
      <code>httpd.exe</code> binary executable.</li>
    </ol>

    <div class="note">It is usually a good practice to grant the user the Apache
    service runs as read and execute (RX) access to the whole Apache2.4
    directory, except the <code>logs</code> subdirectory, where the
    user has to have at least change (RWXD) rights.</div>

    <p>If you allow the account to log in as a user and as a service,
    then you can log on with that account and test that the account has
    the privileges to execute the scripts, read the web pages, and that
    you can start Apache in a console window. If this works, and you
    have followed the steps above, Apache should execute as a service
    with no problems.</p>

    <div class="note"><strong>Error code 2186</strong> is a good indication that
    you need to review the "Log On As" configuration for the service,
    since Apache cannot access a required network resource. Also, pay
    close attention to the privileges of the user Apache is
    configured to run as.</div>

    <p>When starting Apache as a service you may encounter an error
    message from the Windows Service Control Manager. For example,
    if you try to start Apache by using the Services applet in the
    Windows Control Panel, you may get the following message:</p>

    <div class="example"><p><code>
      Could not start the Apache2.4 service on \\COMPUTER <br />
      Error 1067; The process terminated unexpectedly.
    </code></p></div>

    <p>You will get this generic error if there is any problem with
    starting the Apache service. In order to see what is really causing
    the problem you should follow the instructions for Running Apache
    for Windows from the Command Prompt.</p>

    <p>If you are having problems with the service, it is suggested
    you follow the instructions below to try starting httpd.exe from
    a console window, and work out the errors before struggling to
    start it as a service again.</p>
  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="wincons" id="wincons">Running Apache as a Console Application</a></h2>
    

    <p>Running Apache as a service is usually the recommended way to
    use it, but it is sometimes easier to work from the command line,
    especially during initial configuration and testing.</p>

    <p>To run Apache from the command line as a console application,
    use the following command:</p>

    <div class="example"><p><code>
      httpd.exe
    </code></p></div>

    <p>Apache will execute, and will remain running until it is stopped
    by pressing Control-C.</p>

    <p>You can also run Apache via the shortcut Start Apache in Console
    placed to <code>Start Menu --&gt; Programs --&gt; Apache HTTP Server
    2.4.xx --&gt; Control Apache Server</code> during the installation.
    This will open a console window and start Apache inside it. If you
    don't have Apache installed as a service, the window will remain
    visible until you stop Apache by pressing Control-C in the console
    window where Apache is running in. The server will exit in a few
    seconds. However, if you do have Apache installed as a service, the
    shortcut starts the service. If the Apache service is running
    already, the shortcut doesn't do anything.</p>

    <p>If Apache is running as a service, you can tell it to stop by opening another console
    window and entering:</p>

    <div class="example"><p><code>
      httpd.exe -k shutdown
    </code></p></div>

    <p>Running as a service should be preferred over running in a
    console window because this lets Apache end any current operations
    and clean up gracefully.</p>

    <p>But if the server is running in a console window, you can
    only stop it by pressing Control-C in the same window.</p>

    <p>You can also tell Apache to restart. This forces it to reread
    the configuration file. Any operations in progress are allowed to
    complete without interruption. To restart Apache, either press
    Control-Break in the console window you used for starting Apache,
    or enter</p>

    <div class="example"><p><code>
      httpd.exe -k restart
    </code></p></div>

    <p>if the server is running as a service.</p>

    <div class="note">Note for people familiar with the Unix version of Apache:
    these commands provide a Windows equivalent to <code>kill -TERM
    <em>pid</em></code> and <code>kill -USR1 <em>pid</em></code>. The
    command line option used, <code>-k</code>, was chosen as a reminder
    of the <code>kill</code> command used on Unix.</div>

    <p>If the Apache console window closes immediately or unexpectedly
    after startup, open the Command Prompt from the Start Menu --&gt;
    Programs. Change to the folder to which you installed Apache, type
    the command <code>httpd.exe</code>, and read the error message. Then
    change to the logs folder, and review the <code>error.log</code>
    file for configuration mistakes. Assuming httpd was installed into
    <code>C:\Program Files\Apache Software Foundation\Apache2.4\</code>,
    you can do the following:</p>

    <div class="example"><p><code>
      c: <br />
      cd "\Program Files\Apache Software Foundation\Apache2.4\bin" <br />
      httpd.exe
    </code></p></div>

    <p>Then wait for Apache to stop, or press Control-C. Then enter the
    following:</p>

    <div class="example"><p><code>
      cd ..\logs <br />
      more &lt; error.log
    </code></p></div>

    <p>When working with Apache it is important to know how it will
    find the configuration file. You can specify a configuration file
    on the command line in two ways:</p>

    <ul>
      <li><p><code>-f</code> specifies an absolute or relative path to
      a particular configuration file:</p>

      <div class="example"><p><code>
        httpd.exe -f "c:\my server files\anotherconfig.conf"
      </code></p></div>

      <p>or</p>

      <div class="example"><p><code>
        httpd.exe -f files\anotherconfig.conf
      </code></p></div></li>

      <li><p><code>-n</code> specifies the installed Apache service
      whose configuration file is to be used:</p>

      <div class="example"><p><code>
        httpd.exe -n "MyServiceName"
      </code></p></div>
      </li>
    </ul>

    <p>In both of these cases, the proper
    <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> should be set in
    the configuration file.</p>

    <p>If you don't specify a configuration file with <code>-f</code>
    or <code>-n</code>, Apache will use the file name compiled into the
    server, such as <code>conf\httpd.conf</code>. This built-in path
    is relative to the installation directory. You can verify the compiled
    file name from a value labelled as <code>SERVER_CONFIG_FILE</code> when
    invoking Apache with the <code>-V</code> switch, like this:</p>

    <div class="example"><p><code>
      httpd.exe -V
    </code></p></div>

    <p>Apache will then try to determine its <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> by trying the following, in this order:</p>

    <ol>
      <li>A <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directive
      via the <code>-C</code> command line switch.</li>

      <li>The <code>-d</code> switch on the command line.</li>

      <li>Current working directory.</li>

      <li>A registry entry which was created if you did a binary
      installation.</li>

      <li>The server root compiled into the server. This is <code>
      /apache</code> by default, you can verify it by using <code>
      httpd.exe -V</code> and looking for a value labelled as
      <code>HTTPD_ROOT</code>.</li>
    </ol>

    <p>If you did not do a binary install, Apache will in some
    scenarios complain about the missing registry key. This warning can
    be ignored if the server was otherwise able to find its
    configuration file.</p>

    <p>The value of this key is the
    <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directory which
    contains the <code>conf</code> subdirectory. When Apache starts it
    reads the <code>httpd.conf</code> file from that directory. If
    this file contains a <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>
    directive which contains a different directory from the one
    obtained from the registry key above, Apache will forget the
    registry key and use the directory from the configuration file. If
    you copy the Apache directory or configuration files to a new
    location it is vital that you update the
    <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directive in the
    <code>httpd.conf</code> file to reflect the new location.</p>

<h2><a name="test" id="test">Testing the Installation</a></h2>
    

    <p>After starting Apache (either in a console window or as a
    service) it will be listening on port 80 (unless you changed the
    <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> directive in the
    configuration files or installed Apache only for the current user).
    To connect to the server and access the default page, launch a
    browser and enter this URL:</p>

    <div class="example"><p><code>
      http://localhost/
    </code></p></div>

    <p>Apache should respond with a welcome page and you should see
    "It Works!". If nothing happens or you get an error, look in the
    <code>error.log</code> file in the <code>logs</code> subdirectory.
    If your host is not connected to the net, or if you have serious
    problems with your DNS (Domain Name Service) configuration, you
    may have to use this URL:</p>

    <div class="example"><p><code>
      http://127.0.0.1/
    </code></p></div>

    <p>If you happen to be running Apache on an alternate port, you
    need to explicitly put that in the URL:</p>

    <div class="example"><p><code>
      http://127.0.0.1:8080/
    </code></p></div>

    <p>Once your basic installation is working, you should configure it
    properly by editing the files in the <code>conf</code> subdirectory.
    Again, if you change the configuration of the Windows NT service
    for Apache, first attempt to start it from the command line to
    make sure that the service starts with no errors.</p>

    <p>Because Apache <strong>cannot</strong> share the same port with
    another TCP/IP application, you may need to stop, uninstall or reconfigure
    certain other services before running Apache. These conflicting
    services include other WWW servers, some firewall implementations,
    and even some client applications (such as Skype) which will use port
    80 to attempt to bypass firewall issues.</p>

<h2><a name="windrivemap" id="windrivemap">Configuring Access to Network Resources</a></h2>
    

  <p>Access to files over the network can be specified using two
  mechanisms provided by Windows:</p>

  <dl>
    <dt>Mapped drive letters</dt>
    <dd>e.g., <code>Alias "/images/" "Z:/"</code></dd>

    <dt>UNC paths</dt>
    <dd>e.g., <code>Alias "/images/" "//imagehost/www/images/"</code></dd>
  </dl>

  <p>Mapped drive letters allow the administrator to maintain the
  mapping to a specific machine and path outside of the Apache httpd
  configuration.  However, these mappings are associated only with
  interactive sessions and are not directly available to Apache httpd
  when it is started as a service.  <strong>Use only UNC paths for
  network resources in httpd.conf</strong> so that the resources can
  be accessed consistently regardless of how Apache httpd is started.
  (Arcane and error prone procedures may work around the restriction
  on mapped drive letters, but this is not recommended.)</p>

  <div class="example"><h3>Example DocumentRoot with UNC path</h3><pre class="prettyprint lang-config">DocumentRoot "//dochost/www/html/"</pre>
</div>

  <div class="example"><h3>Example DocumentRoot with IP address in UNC path</h3><pre class="prettyprint lang-config">DocumentRoot "//192.168.1.50/docs/"</pre>
</div>

  <div class="example"><h3>Example Alias and corresponding Directory with UNC path</h3><pre class="prettyprint lang-config">Alias "/images/" "//imagehost/www/images/"

&lt;Directory "//imagehost/www/images/"&gt;
#...
&lt;/Directory&gt;</pre>
</div>

  <p>When running Apache httpd as a service, you must create a
  separate account in order to access network resources, as described
  above.</p>

<pre>Date: Wed, 05 Nov 1997 16:59:34 -0800
From: Rick Jones &lt;<a href="mailto:raj@cup.hp.com">raj@cup.hp.com</a>&gt;
Reply-To: <a href="mailto:raj@cup.hp.com">raj@cup.hp.com</a>
Organization: Network Performance
Subject: HP-UX tuning tips</pre>

    <p>Here are some tuning tips for HP-UX to add to the tuning page.</p>

    <p>For HP-UX 9.X: Upgrade to 10.20<br />
    For HP-UX 10.[00|01|10]: Upgrade to 10.20</p>

    <p>For HP-UX 10.20:</p>

    <p>Install the latest cumulative ARPA Transport Patch. This
    will allow you to configure the size of the TCP connection
    lookup hash table. The default is 256 buckets and must be set
    to a power of two. This is accomplished with adb against the
    *disc* image of the kernel. The variable name is <code>tcp_hash_size</code>.
    Notice that it's critically important that you use "<code>W</code>"
    to write a 32 bit quantity, not "<code>w</code>" to write a 16 bit
    value when patching the disc image because the <code>tcp_hash_size</code>
    variable is a 32 bit quantity.</p>

    <p>How to pick the value? Examine the output of <a href="ftp://ftp.cup.hp.com/dist/networking/tools/connhist">ftp://ftp.cup.hp.com/dist/networking/tools/connhist</a>
    and see how many total TCP connections exist on the system. You
    probably want that number divided by the hash table size to be
    reasonably small, say less than 10. Folks can look at HP's
    SPECweb96 disclosures for some common settings. These can be
    found at <a href="http://www.specbench.org/">http://www.specbench.org/</a>.
    If an HP-UX system was performing at 1000 SPECweb96 connections
    per second, the <code>TIME_WAIT</code> time of 60 seconds would mean
    60,000 TCP "connections" being tracked.</p>

    <p>Folks can check their listen queue depths with <a href="ftp://ftp.cup.hp.com/dist/networking/misc/listenq">ftp://ftp.cup.hp.com/dist/networking/misc/listenq</a>.</p>

    <p>If folks are running Apache on a PA-8000 based system, they
    should consider "chatr'ing" the Apache executable to have a
    large page size. This would be "<code>chatr +pi L &lt;BINARY&gt;</code>".
    The GID of the running executable must have <code>MLOCK</code> privileges.
    <code>Setprivgrp(1m)</code> should be consulted for assigning
    <code>MLOCK</code>. The change can be validated by running Glance
    and examining the memory regions of the server(s) to make sure that
    they show a non-trivial fraction of the text segment being locked.</p>

    <p>If folks are running Apache on MP systems, they might
    consider writing a small program that uses <code>mpctl()</code>
    to bind processes to processors. A simple <code>pid % numcpu</code>
    algorithm is probably sufficient. This might even go into the
    source code.</p>

    <p>If folks are concerned about the number of <code>FIN_WAIT_2</code>
    connections, they can use nettune to shrink the value of
    <code>tcp_keepstart</code>. However, they should be careful there -
    certainly do not make it less than oh two to four minutes. If
    <code>tcp_hash_size</code> has been set well, it is probably OK to
    let the <code>FIN_WAIT_2</code>'s take longer to timeout (perhaps
    even the default two hours) - they will not on average have a big
    impact on performance.</p>

    <p>There are other things that could go into the code base, but
    that might be left for another email. Feel free to drop me a
    message if you or others are interested.</p>

    <p>sincerely,</p>

    <p>rick jones</p>

    <p>Il y a de nombreux points importants à connaître avant de
    compiler Le serveur HTTP Apache pour Microsoft Windows. Avant de commencer, lisez le
    document <a href="windows.html">Utiliser le serveur HTTP Apache avec Microsoft
    Windows</a>.</p>

    <p>httpd peut être compilé sous Windows en utilisant une chaîne de
    compilation basée sur cmake, ou à partir de fichiers projet Visual
    Studio maintenus par les développeurs de httpd. La chaîne de
    compilation basée sur cmake supporte directement davantage de
    versions de Visual Studio, mais possède actuellement des
    fonctionnalités très limitées.</p>

<h2><a name="requirements" id="requirements">Prérequis</a></h2>

    

    <p>Pour compiler Apache, l'environnement doit satisfaire aux
    conditions suivantes :</p>

    <ul>
      <li>
        <p>Espace disque</p>

        <p>Assurez-vous de disposer d'un minimum de 200 Mo d'espace
	disque disponible. Après l'installation, Apache occupe environ
	80 Mo d'espace disque, plus l'espace réservé aux journaux et au
	cache, la taille de ces derniers pouvant augmenter rapidement.
	Les besoins réels en espace disque dépendent étroitement de la
	configuration choisie et des bibliothèques ou modules tiers
	installés, en particulier lorsqu'OpenSSL est mis en oeuvre.
	Comme de nombreux fichiers sont au format texte et donc
	facilement compressibles, l'utilisation de la compression du
	système de fichiers NTFS divise ces besoins par deux.</p>
      </li>

      <li>
        <p>Correctifs requis</p>

        <p>Le binaire httpd est compilé à l'aide de nombreux correctifs
	appliqués aux paquets tiers, ce qui permet de s'assurer que le
	code fourni est bien compilable et déboguable. Ces correctifs
	sont disponibles à <a href="http://www.apache.org/dist/httpd/binaries/win32/patches_applied/">http://www.apache.org/dist/httpd/binaries/win32/patches_applied/</a>,
	et il est recommandé de les appliquer afin d'obtenir un
	résultat identique aux binaires "officiels" distribués par
	l'ASF.</p>
      </li>

      <li>
        <p>Microsoft Visual C++ 6.0 (Visual Studio 97) ou supérieur.</p>

        <p>Apache peut être compilé en utilisant l'outil ligne de
	commande, ou depuis l'espace de travail IDE Visual Studio. Pour
	la compilation depuis la ligne de commandes, l'environnement
	doit comporter les variables the <code>PATH</code>,
	<code>INCLUDE</code>, <code>LIB</code>, ainsi que d'autres
	variables qui peuvent être définies via le script
	<code>vcvars32.bat</code> :</p>

        <div class="note">Vous pouvez vous procurer le paquet du Processeur Visual
	Studio pour votre ancienne version de Visual Studio, ou une
	version complète (et non Express) d'une édition plus récente de
	Visual Studio pour l'assembleur ml.exe. Ceci vous permettra, si
	vous le souhaitez, de compiler OpenSSL en utilisant une
	implémentation du code d'assemblage plus efficace.</div>

        <div class="note">Seule la chaîne d'outils de compilation de Microsoft est
	supportée de manière suivie par les contributeurs actifs à httpd.
	Bien que le projet accepte régulièrement des correctifs pour
	s'assurer que MinGW et d'autre outils de compilation
	fonctionnent, ou même pour les améliorer, ils ne sont pas
	maintenus de manière suivie et sont même souvent hors d'état
	de fonctionner à certains stades du développement normal.</div>
      </li>

      <li>
        <p>Le SDK de la plate-forme Windows mis à jour, février 2003 ou
	plus récent.</p>

	<p>Un SDK approprié pour la plate-forme Windows est inclus par
	défaut dans les versions complètes (et non Express/lite) de
	Visual C++ 7.1 (Visual Studio 2002) et supérieures ; les
	utilisateurs peuvent ignorer ces étapes, à moins qu'ils aient
	choisi d'utiliser une version plus récente ou différente du SDK.</p>

	<p>Pour pouvoir utiliser Visual C++ 6.0 or 7.0 (Studio 2000
	.NET), l'environnement du SDK de la plate-forme doit être préparé en utilisant le
	script <code>setenv.bat</code> (installé par le SDK de la plate-forme) avant de
	lancer la compilation en ligne de commande ou l'interface GUI
	msdev/devenv. L'installation du SDK de la plate-forme pour les
	versions Express de Visual Studio (2003 et supérieures) devrait
	ajuster l'environnement par défaut de manière appropriée.</p>

        <div class="example"><p><code>
	  "c:\Program Files\Microsoft Visual Studio\VC98\Bin\VCVARS32"<br />

      <li>
        <p>Perl et awk</p>

	<p>De nombreuses étapes recommandées ici nécessitent un
	interpréteur perl durant le processus de préparation de la
	compilation.</p>

        <p>Pour installer Apache à partir du système de compilation, de
	nombreux fichiers sont modifiés via l'utilitaire
	<code>awk.exe</code>. awk effectue la modification des fichiers
	au moment de l'installation ; il a été choisi car il nécessite
	un téléchargement de petite taille (par rapport à Perl ou
	WSH/VB). Le site de Brian Kernighan <a href="http://www.cs.princeton.edu/~bwk/btl.mirror/">http://www.cs.princeton.edu/~bwk/btl.mirror/</a> propose un
	binaire précompilé pour Win32, <a href="http://www.cs.princeton.edu/~bwk/btl.mirror/awk95.exe">http://www.cs.princeton.edu/~bwk/btl.mirror/awk95.exe</a>, que
	vous devez enregistrer sous le nom <code>awk.exe</code> (plutôt
	que <code>awk95.exe</code>).</p>

        <div class="note">Si awk.exe n'est pas trouvé, la cible install du fichier
	Makefile.win n'effectuera aucune substitution dans les fichiers
	.conf installés. Vous devez modifier manuellement les fichiers
	.conf installés afin de permettre au serveur de démarrer.
	Recherchez et remplacez toutes les balises "@token@" par une
	valeur appropriée.</div>

        <div class="note">L'IDE Visual Studio ne trouvera le chemin de
	<code>awk.exe</code> que dans la variable PATH, ou dans le
	chemin des exécutables spécifié par l'option de menu Tools -&gt;
	Options -&gt; (Projects -&gt;) Directories. Assurez-vous
	qu'awk.exe est bien dans votre chemin système.</div>

        <div class="note">Notez aussi, si vous utilisez les outils Cygwin (<a href="http://www.cygwin.com/">http://www.cygwin.com/</a>), que
	l'utilitaire awk de nomme <code>gawk.exe</code> et que le
	fichier <code>awk.exe</code> est en fait un lien symbolique vers
	le fichier <code>gawk.exe</code>. Le shell de commandes Windows
	ne reconnaît pas les liens symboliques, et par conséquent la
	compilation d'InstallBin échouera. Pour contourner le problème,
	vous pouvez supprimer le lien <code>awk.exe</code> de
	l'installation de Cygwin, et copier <code>gawk.exe</code> vers
	<code>awk.exe</code>. Notez aussi que les portages cygwin/mingw
	de gawk 3.0.x étaient bogués ; veuillez par conséquent effectuer
	une mise à jour vers la	version 3.1.x avant l'utilisation de
	tout portage de gawk.</div>

        <p>[Optionnel] bibliothèque zlib (pour le module
	<code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code>)</p>

        <p>Zlib doit être installée dans un sous-répertoire du
	répertoire <code>srclib</code> et nommé <code>zlib</code>. Elle
	doit être compilée directement à cette place. Zlib est
	disponible à l'adresse <a href="http://www.zlib.net/">http://www.zlib.net/</a> -- le
	fonctionnement correct du module <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code> a
	été vérifié avec la version 1.2.3.</p>

        <div class="example"><p><code>

      <li>
        <p>[Optionnel] Bibliothèques OpenSSL (pour le module
	<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> et <code>ab.exe</code> avec le support
	ssl)</p>

	<div class="note">La bibliothèque OpenSSL est un logiciel de chiffrement. Le
	pays dans lequel vous résidez peut imposer des restrictions à
	l'importation, la possession, l'utilisation, et/ou la
	réexportation vers un autre pays des logiciels de chiffrement.
	AVANT d'utiliser tout logiciel de chiffrement, veuillez
	consulter la législation de votre pays, les règles et politiques
	d'importation, de possession, ou d'utilisation, et de
	réexportation des logiciels de chiffrement, afin de déterminer
	si vous en avez le droit. Voir <a href="http://www.wassenaar.org/">http://www.wassenaar.org/</a>
	pour plus de détails.</div>

        <p>La configuration et la compilation d'OpenSSL nécessite
	l'installation de perl.</p>

        <p>Pour pouvoir compiler <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> ou le projet
	<code>abs.exe</code>, qui devient ab.c avec le support SSL
	activé, vous devez
	télécharger OpenSSL à l'adresse <a href="http://www.openssl.org/source/">http://www.openssl.org/source/</a>,
	et l'installer dans un sous-répertoire du répertoire
	<code>srclib</code> que vous nommerez <code>openssl</code>. Afin
	de préparer OpenSSL à la liaison avec le module Apache mod_ssl
	ou abs.exe, et désactiver les fonctionnalités d'Openssl grévées
	de brevets, vous pouvez utiliser la commande de compilation
	suivante :</p>

        <div class="example"><p><code>
          perl Configure no-rc5 no-idea enable-mdc2 enable-zlib VC-WIN32
               -Ipath/to/srclib/zlib -Lpath/to/srclib/zlib<br />
          ms\do_masm.bat<br />
          nmake -f ms\ntdll.mak
        </code></p></div>

        <div class="note">Il est déconseillé d'utiliser zlib-dynamic, car la charge
	de la décompression des flux SSL est alors transférée à la
	première requête qui doit charger la dll zlib. Notez que le
	correctif proposé active le drapeau -L afin de pouvoir
	fonctionner avec les compilations Windows, corrige le nom de
	zdll.lib et s'assure que les fichiers .pdb sont générés afin de
	pouvoir résoudre les problèmes. Si l'assembleur n'est pas
	installé, vous devez ajouter no-asm ci-dessus et utiliser le
	script ms\do_ms.bat à la place de ms\do_masm.bat.</div>
      </li>

      <li>
        <p>[Optionnel] Bibliothèques de bases de données (pour
<code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> et <code class="module"><a href="../mod/mod_authn_dbm.html">mod_authn_dbm</a></code>)</p>

        <p>La bibliothèque apr-util fournit un accès aux fonctionnalités
	clients dbm (base de données à base de clés) et dbd (base de
	données à base de requêtes) au serveur httpd et à certains de
	ses modules, comme les modules d'authentification et
	d'autorisation. Les fournisseurs sdbm dbm et odbc dbd sont
	compilés automatiquement.</p>

        <p>Le support dbd inclut le paquet instantclient Oracle, MySQL,
	PostgreSQL et sqlite. Par exemple, pour les compiler tous,
	définissez LIB de façon à inclure le chemin des bibliothèques,
	INCLUDE de façon à inclure le chemin des en-têtes, et PATH de
	façon à inclure le chemin des dll et bin de chacun des quatre
	SDK, et définissez la variable d'environnement DBD_LIST de façon
	à indiquer au processus de compilation quels SDKs pilotes
	clients du sont correctement installés ; par exemple :</p>

        <div class="example"><p><code>
          set DBD_LIST=sqlite3 pgsql oracle mysql
        </code></p></div>

        <p>De manière similaire, le support dbm peut être étendu avec
	DBM_LIST pour compiler un fournisseur Berkeley DB (db) et/ou un
	fournisseur gdbm, en configurant tout d'abord de la même manière
	LIB, INCLUDE et PATH afin de s'assurer que les bibliothèques et
	en-têtes de la bibliothèque client sont bien disponibles.</p>

        <div class="example"><p><code>
          set DBM_LIST=db gdbm
        </code></p></div>

        <div class="note">En fonction du choix des distributions de bases de
	données, il peut s'avérer nécessaire de modifier le nom des
	cibles de l'édition de liens (par exemple gdbm.lib à la place de
	libgdb.lib) listées dans les fichiers .dsp/.mak des répertoires
	srclib\apr-util\dbd ou ...\dbm correspondants.</div>

<h2><a name="unixsrcbuild" id="unixsrcbuild">Compilation à partir des sources Unix</a></h2>

    

    <p>Le projet du serveur HTTP Apache à pour politique de ne fournir
    que des sources de type Unix. Les paquets source de type Windows
    disponibles en téléchargement ont été élaborés par des
    contributeurs, et ne seront pas forcément reconduits pour toutes les
    versions. Vous pouvez cependant compiler le serveur sous Windows à
    partir des sources Unix en ajoutant quelques étapes supplémentaires.</p>

    <ol>
    	<li>Téléchargez et ouvrez le tarball source Unix de la dernière
	version du serveur HTTP Apache.</li>
    	<li>Téléchargez et ouvrez le tarball source Unix de la dernière
	version de APR, APR-Util et APR-Iconv, et copier l'arborescence
	obtenue dans httpd-2.x.x\srclib\apr, httpd-2.x.x\srclib\apr-util
	et httpd-2.x.x\srclib\apr-iconv</li>
    	<li>Ouvrez la console et placez-vous au niveau du répertoire httpd-2.x.x</li>
    	<li>Exécutez l'utilitaire de conversion de fins de ligne</li>
    </ol>

    <div class="example"><p><code>
      perl srclib\apr\build\lineends.pl
    </code></p></div>

    <p>Vous pouvez maintenant compiler le serveur via l'environnement de
    développement Visual Studio en utilisant l'IDE. Les compilations
    du serveur en ligne de commande ne sont possibles avec des sources
    de type Unix que si vous exportez les fichiers .mak comme indiqué
    ci-dessous.

<h2><a name="commandbuild" id="commandbuild">Compilation à partir de la ligne de commandes</a></h2>

    

    <p><code>Makefile.win</code> est le makefile principal ou racine
    d'Apache. Pour compiler Apache sous Windows, utilisez simplement une
    des commandes suivantes pour compiler la version
    <code>release</code> ou <code>debug</code> :</p>

    <div class="example"><p><code>
      nmake /f Makefile.win _apacher<br /><br />
      nmake /f Makefile.win _apached
    </code></p></div>


    <p>Ces deux commandes effectuent la compilation d'Apache. Cependant,
    avec la deuxième, les fichiers résultants ne seront pas optimisés,
    ce qui va faciliter l'examen pas à pas du code pour trouver des
    bogues et résoudre les problèmes.</p>

    <p>Vous pouvez indiquer vos choix en matière de fournisseurs dbd et

<h2><a name="workspacebuild" id="workspacebuild">Compilation depuis l'espace de travail IDE de Developer
    Studio</a></h2>

    

    <p>Apache peut aussi être compilé depuis l'environnement de
    développement Visual Studio de VC++. Pour simplifier ce processus,
    l'espace de travail Visual Studio <code>Apache.dsw</code> est
    fourni. Cet espace de travail expose la liste complète des projets
    <code>.dsp</code> actifs nécessaires à l'installation binaire
    complète d'Apache. Il inclut les dépendances entre projets afin que
    ces derniers soient compilés selon l'ordre approprié.</p>

    <p>Ouvrez l'espace de travail <code>Apache.dsw</code>, et
    sélectionnez <code>InstallBin</code> (compilation
    <code>Release</code> ou <code>Debug</code>, selon vos souhaits)
    comme Active Project. <code>InstallBin</code> provoque la
    compilation de tous les projets concernés, puis invoque
    <code>Makefile.win</code> pour installer les exécutables et dlls
    compilés. Vous pouvez modifier la valeur de <code>INSTDIR=</code>
    via la configuration de <code>InstallBin</code>, onglet Général,
    entrée ligne de commandes de compilation. La valeur par défaut de
    <code>INSTDIR</code> est le répertoire <code>/Apache2</code>. Si
    vous désirez effectuer un test de compilation (sans installation),
    sélectionnez le projet <code>BuildBin</code>.</p>

    <p>Les fichiers projets <code>.dsp</code> sont distribués au format
    Visual Studio 6.0 (98). Visual C++ 5.0 (97) les reconnaît. Les
    utilisateurs de Visual Studio 2002 (.NET) et versions supérieures
    doivent convertir <code>Apache.dsw</code> et les fichiers
    <code>.dsp</code> en un projet <code>Apache.sln</code>, ainsi que
    les fichiers <code>.msproj</code> ; assurez-vous de reconvertir le
    fichier <code>.msproj</code> si l'un des fichiers source
    <code>.dsp</code> est modifié ! Cette opération est vraiment très
    simple, il suffit de réouvrir <code>Apache.dsw</code> dans l'IDE
    VC++ 7.0 et de le reconvertir.</p>

    
    <div class="note">Il y a une erreur dans la conversion .vcproj des fichiers
    .dsp. devenv.exe interprète mal le drapeau
    /D pour les drapeaux RC contenant de grandes /D'éfinitions entourées
    de guillemets, et contenant elles-mêmes des espaces. Ainsi, la
    commande :
    <div class="example"><p><code>
      perl srclib\apr\build\cvtdsp.pl -2005
    </code></p></div>
    va convertir les drapeaux /D pour les drapeaux RC afin d'utiliser
    une syntaxe alternative, interprétable ; malheureusement, cette
    syntaxe n'est pas supportée par Visual Studio 97 ou ses fichiers
    .mak exportés. Ces drapeaux /D permettent de transmettre la longue
    description des fichiers de mod_apachemodule.so à leurs compilations
    d'identificateur de version de ressource .rc partagée.</div>

    
	<div class="note"><strong>Compilation avec OpenSSL versions 1.1.0 et supérieures</strong>
    Suite à une modification de la structure de compilation d'OpenSSL à partir

    et <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code> pour <code>abs</code>. Ces modules
    sont compilés
    en invoquant <code>nmake</code> ou directement l'IDE avec la cible
    <code>BinBuild</code> pour compiler ces modules de manière
    conditionnelle si les sous-répertoires de <code>srclib</code>
    <code>openssl</code> et/ou <code>zlib</code> existent, et en

<h2><a name="exportingmakfiles" id="exportingmakfiles">Export des fichiers .mak de la ligne de commandes</a></h2>

    


    <p>Les fichiers <code>.mak</code> exportés posent plus de problèmes,
    mais les utilisateurs de Visual C++ 5.0 en ont besoin pour compiler
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>, abs (<code class="program"><a href="../programs/ab.html">ab</a></code> avec support
    SSL) et/ou <code class="module"><a href="../mod/mod_deflate.html">mod_deflate</a></code>. Les fichiers .mak
    supportent aussi un choix plus large de distributions de chaînes
    d'outils C++, comme Visual Studio Express.</p>

    <p>Vous devez tout d'abord compiler tous les projets afin de créer
    toutes les cibles dynamiques auto-générées, de façon à ce que les
    dépendances puissent être interprétées correctement. Compilez
    l'ensemble du projet depuis l'IDE Visual Studio 6.0 (98), en
    utilisant la cible <code>BuildAll</code>, puis utilisez le menu de
    projet Export pour tous les makefiles (en cochant "with
    dependencies"). Utilisez la commande suivante pour transformer les
    chemins absolus en chemins relatifs de façon à ce que la compilation
    puisse s'effectuer depuis n'importe quelle position dans
    l'arborescence :</p>

    <div class="example"><p><code>
      perl srclib\apr\build\fixwin32mak.pl
    </code></p></div>

    <p>Vous devez exécuter cette commande depuis la <em>racine</em> de
    l'arborescence des sources de httpd. Tout fichier projet
    <code>.mak</code> et <code>.dep</code> du répertoire courant et de
    ses sous-répertoires sera corrigé, et les repères de temps ajustés
    en fonction des <code>.dsp</code>.</p>

    <p>Vérifiez toujours le SDK de la plate-forme ou autres chemins
    fichiers locaux, spécifiques à la machine dans les fichiers
    <code>.mak</code> et <code>.dep</code> générés. Le répertoire
    <code>DevStudio\Common\MSDev98\bin\</code> (VC6) contient un fichier
    <code>sysincl.dat</code> qui énumère toutes les exceptions. Mettez à
    jour ce fichier (en particulier les chemins avec slashes et
    anti-slashes, tels que <code>sys/time.h</code> et
    <code>sys\time.h</code>) de façon à ignorer ces nouvelles
    dépendances. Inclure les chemins d'installation locale dans un
    fichier <code>.mak</code> distribué fera échouer la
    compilation.</p>

    <p>Si vous soumettez un patch qui modifie les fichiers projet, nous
    devons valider la modification de ces fichiers projet au format
    Visual Studio 6.0. Les modifications doivent êtres simples, avec un
    minimum de drapeaux de compilation et d'édition de liens qui
    pourront être reconnus par tous les environnements Visual
    Studio.</p>

    <p>Une fois compilé, Apache doit être installé dans le répertoire

    <li>La compilation du sous-projet APR-util avec cmake ne supporte

Reply-To: <a href="mailto:raj@cup.hp.com">raj@cup.hp.com</a>
Organization: Network Performance
Subject: HP-UX tuning tips</pre>

    <p>Traduction du corps du message cité ci-dessus :</p>

    <p>Voici quelques conseils de personnalisation pour HPUX à ajouter à
    la page de personnalisation.</p>

    <p>Pour HP-UX 9.X: mettre à jour vers la version 10.20<br />
    Pour HP-UX 10.[00|01|10]: mettre à jour vers la version 10.20</p>

    <p>Pour HP-UX 10.20:</p>

    <p>Installez le dernier patch cumulatif à propos du transport ARPA.
    Ceci va vous permettre de configurer la taille de la table de
    hashage de recherche de connexion TCP. La valeur par défaut est 256
    conteneurs et doit être une puissance de deux. À cet effet, utilisez
    adb pour modifier l'image *disque* du noyau. Le nom de la variable
    est <code>tcp_hash_size</code>. Notez qu'il est impératif d'utiliser
    "<code>W</code>" pour spécifier une quantité sur 32 bits, et non
    "<code>w</code>" qui indique une valeur sur 16 bits, lors de la
    modification de l'image disque car la variable
    <code>tcp_hash_size</code> est une quantité sur 32 bits.</p>

    <p>Comment déterminer cette valeur ? Examinez la sortie de <a href="ftp://ftp.cup.hp.com/dist/networking/tools/connhist">ftp://ftp.cup.hp.com/dist/networking/tools/connhist</a>, et
    comptez le nombre total de connexions TCP existant sur le système.
    Il est en général souhaitable que ce nombre divisé par la taille de
    la table de hashage soit raisonnablement petit, disons inférieur à
    10. Les administrateurs peuvent consulter le document SPECweb96 de
    HP pour quelques réglages courants. On peut les trouver à <a href="http://www.specbench.org/">http://www.specbench.org/</a>. Si
    un système HP-UX traite 1000 connexions SPECweb96 par seconde, une
    valeur de temps <code>TIME_WAIT</code> de 60 secondes permettrait le
    suivi de 60000 connexions TCP.</p>

    <p>Les administrateurs peuvent tester la profondeur de leur file
    d'attente d'écoute avec <a href="ftp://ftp.cup.hp.com/dist/networking/misc/listenq">ftp://ftp.cup.hp.com/dist/networking/misc/listenq</a>.</p>

    <p>Si Apache s'exécute sur un système à base de PA-8000, il est
    conseillé de modifier l'exécutable Apache avec la commande chatr
    afin d'utiliser une page de grande taille. La commande sera du style
    "<code>chatr +pi L &lt;BINARY&gt;</code>". Le GID de l'exécutable en
    cours de fonctionnement doit posséder le privilège
    <code>MLOCK</code>. Pour assigner ce privilège <code>MLOCK</code>,
    consultez <code>Setprivgrp(1m)</code>. La modification peut être
    validée en exécutant Glance et en examinant les portions de mémoire
    du/des serveur(s) afin de s'assurer qu'elles montrent une fraction
    non triviale du segment de texte verrouillé.</p>

    <p>Si Apache s'exécute sur un système MP (multi-processeurs), il est
    conseillé d'écrire un petit programme qui utilise
    <code>mpctl()</code> et permettant d'associer les processus aux
    processeurs. Un simple algorithme <code>pid % numcpu</code> suffira
    probablement. Cette modification peut aussi être ajoutée dans le
    code source.</p>

    <p>Si l'administrateur s'intéresse au nombre de connexions
    <code>FIN_WAIT_2</code>, il peut utiliser nettune pour diminuer la
    valeur de <code>tcp_keepstart</code>. Il devra cependant être
    prudent - surtout ne pas diminuer cette valeur en dessous de, disons
    deux à quatre minutes. Si <code>tcp_hash_size</code> a été défini,
    il est probablement approprié de laisser les connexions
    <code>FIN_WAIT_2</code> prendre plus de temps à expirer (peut-être
    même la valeur par défaut de deux heures) - elles n'auront en
    général pas un grand impact sur les performances.</p>

    <p>On peut ajouter d'autres choses au code de base, mais elles
    feront peut-être l'objet d'un autre email. N'hésitez pas à m'envoyer
    un message si vous êtes intéressé.</p>

    <p>sincèrement ,</p>

<h2><a name="req" id="req">Prérequis</a></h2>

    

    <p>Apache 2.0 nécessite NetWare 6.0 service pack 3 et supérieurs
    pour fonctionner. Si vous utilisez un service pack antérieur à SP3,
    vous devez installer les dernières <a href="http://developer.novell.com/ndk/libc.htm">Bibliothèques
    Netware pour C (LibC)</a>.</p>

    <p>Vous trouverez les service packs Netware <a href="http://support.novell.com/misc/patlst.htm#nw">ici</a>.</p>

    <p>Apache 2.0 pour NetWare peut aussi fonctionner dans un
    environnement NetWare 5.1, à partir du moment où le dernier service
    pack ou la dernière version des <a href="http://developer.novell.com/ndk/libc.htm">Bibliothèques
    Netware pour C (LibC)</a> ont été installés. <strong>ATTENTION
    :</strong> Apache 2.0 pour NetWare n'a pas été testé dans cet

<h2><a name="inst" id="inst">Installation d'Apache pour NetWare</a></h2>

    

    <p>Il n'existe pas actuellement de programme d'installation d'Apache
    pour Netware. Si vous installez Apache 2.0 pour NetWare à partir des
    sources, vous devrez copier les fichiers sur le serveur
    manuellement.</p>

    <p>Suivez ces instructions pour installer Apache sous Netware à
    partir de la distribution binaire (en supposant que vous effectuez
    l'installation dans <code>sys:/apache2</code>) :</p>

    <ul>
      <li>Décompressez le fichier binaire téléchargé à la racine du
      volume <code>SYS:</code> (vous pouvez cependant l'installer dans
      tout volume)</li>

      <li>Editez le fichier <code>httpd.conf</code> et définissez les
      directives <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> et
      <code class="directive"><a href="../mod/core.html#servername">ServerName</a></code> avec les valeurs
      correctes des chemins de fichiers qui correspondent à la
      configuration de votre serveur.</li>

      <li>Ajoutez <code>SYS:/APACHE2</code> au chemin de recherche, par
      une commande du style : <div class="example"><p><code>SEARCH ADD
      SYS:\APACHE2</code></p></div></li>

    </ul>

    <p>Suivez ces instructions pour installer Apache pour Netware
    manuellement à partir de votre propre répertoire de sources (en
    supposant que vous effectuez l'installation dans
    <code>sys:/apache2</code>) :</p>

    <ul>
      <li>Créez un répertoire que vous appellerez <code>Apache2</code>
      dans un volume Netware.</li>

      <li>Copiez <code>APACHE2.NLM</code>, <code>APRLIB.NLM</code> dans
      <code>SYS:/APACHE2</code>.</li>

      <li>Créez un répertoire que vous appellerez <code>BIN</code> dans
      <code>SYS:/APACHE2</code>.</li>

      <li>Copiez <code>HTDIGEST.NLM</code>, <code>HTPASSWD.NLM</code>,
      <code>HTDBM.NLM</code>, <code>LOGRES.NLM</code>,
      <code>ROTLOGS.NLM</code> dans <code>SYS:/APACHE2/BIN</code>.</li>

      <li>Créez un répertoire que vous appellerez <code>CONF</code> dans
      <code>SYS:/APACHE2</code>.</li>

      <li>Copiez le fichier <code>HTTPD-STD.CONF</code> dans le
      répertoire <code>SYS:/APACHE2/CONF</code> et renommez-le en
      <code>HTTPD.CONF</code>.</li>

      <li>Copiez les fichiers <code>MIME.TYPES</code>,
      <code>CHARSET.CONV</code> et <code>MAGIC</code> dans le répertoire
      <code>SYS:/APACHE2/CONF</code>.</li>

      <li>Copiez tous les fichiers et sous-répertoires de
      <code>\HTTPD-2.0\DOCS\ICONS</code> dans
      <code>SYS:/APACHE2/ICONS</code>.</li>

      <li>Copiez tous les fichiers et sous-répertoires de
      <code>\HTTPD-2.0\DOCS\MANUAL</code> dans
      <code>SYS:/APACHE2/MANUAL</code>.</li>

      <li>Copiez tous les fichiers et sous-répertoires de
      <code>\HTTPD-2.0\DOCS\ERROR</code> dans
      <code>SYS:/APACHE2/ERROR</code>.</li>

      <li>Copiez tous les fichiers et sous-répertoires de
      <code>\HTTPD-2.0\DOCS\DOCROOT</code> dans
      <code>SYS:/APACHE2/HTDOCS</code>.</li>

      <li>Créez le répertoire <code>SYS:/APACHE2/LOGS</code> sur le
      serveur.</li>

      <li>Créez le répertoire <code>SYS:/APACHE2/CGI-BIN</code> sur le
      serveur.</li>

      <li>Créez le répertoire <code>SYS:/APACHE2/MODULES</code> et
      copiez tous les modules nlm dans le répertoire
      <code>modules</code>.</li>

      <li>Editez le fichier <code>HTTPD.CONF</code>, et recherchez
      toutes les marques <code>@@Value@@</code> afin de les remplacer
      par les valeurs appropriées.</li>

      <li>Ajoutez <code>SYS:/APACHE2</code> au chemin de recherche, par
      une commande du style : <div class="example"><p><code>SEARCH ADD
      SYS:\APACHE2</code></p></div>.</li>
    </ul>

    <p>Outre le volume par défaut <code>SYS</code>, Apache peut être
    installé dans tout autre volume.</p>

    <p>Au cours du processus d'installation, l'ajout du mot-clé
    "install" à la ligne de commande du makefile va provoquer la
    construction d'une distribution complète sous forme d'un paquetage
    dans le sous-répertoire <code>DIST</code>. Vous pouvez simplement
    installer Apache en copiant la distribution créée précédemment à la
    racine d'un volume Netware (voir <a href="#comp">Compilation
    d'Apache pour NetWare</a> ci-dessous).</p>

<div class="section">
<h2><a name="run" id="run">Exécuter Apache pour NetWare</a></h2>

    

    <p>Pour démarrer Apache, tapez simplement <code>apache</code> dans
    la console. Ceci aura pour effet de charger Apache dans l'espace
    d'adressage du système d'exploitation. Si vous préférez charger
    Apache dans un espace d'adressage protégé, vous pouvez spécifier cet
    espace d'adressage à l'aide de l'instruction de chargement suivante
    :</p>

    <div class="example"><p><code>
      load address space = apache2 apache2
    </code></p></div>

    <p>Cette instruction va charger Apache dans un espace d'adressage
    appelé apache2. Il est possible d'exécuter plusieurs instances
    simultanées d'Apache sous Netware, en chargeant chacune d'entre
    elles dans son propre espace d'adressage protégé.</p>

    <p>Une fois démarré, Apache écoute le port 80 (à moins que vous
    n'ayez modifié la directive <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> dans les fichiers de
    configuration). Pour vous connecter au serveur et afficher la page
    par défaut, lancez un navigateur et entrez le nom du serveur ou son
    adresse IP. Vous devriez voir une page de bienvenue, et un lien vers
    le manuel Apache. Si rien ne se produit, ou si vous obtenez un
    message d'erreur, consultez le fichier <code>error_log</code> dans
    le répertoire <code>logs</code>.</p>

    <p>Lorsque votre installation de base fonctionne, vous devez la
    configurer correctement en éditant les fichiers du répertoire
    <code>conf</code>.</p>

    <p>Pour arrêter une instance d'Apache s'exécutant dans l'espace
    d'adressage du système d'exploitation, entrez simplement dans la
    console :</p>

    <div class="example"><p><code>
      unload apache2
    </code></p></div>

    <p>ou</p>

    <div class="example"><p><code>
      apache2 shutdown
    </code></p></div>

    <p>Si Apache s'exécute dans un espace d'adressage protégé, spécifiez
    cet espace d'adressage dans l'instruction d'arrêt :</p>

    <div class="example"><p><code>
      unload address space = apache2 apache2
    </code></p></div>

    <p>Lorsqu'on travaille avec Apache, il est important de savoir
    comment il trouve ses fichiers de configuration. Vous pouvez
    spécifier un fichier de configuration sur la ligne de commande de
    deux manières :</p>

    <ul>
      <li><code>-f</code> spécifie un chemin vers un fichier de
      configuration particulier</li>
    </ul>

    <div class="example"><p><code>
      apache2 -f "vol:/nom-serveur/conf/fich-conf.conf"
    </code></p></div>

    <div class="example"><p><code>
      apache -f test/test.conf
    </code></p></div>

    <p>Dans ces cas, la directive <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> doit être correctement définie
    dans le fichier de configuration.</p>

    <p>Si vous ne spécifiez pas de nom de fichier de configuration avec
    l'option <code>-f</code>, Apache utilisera le nom de fichier codé en
    dur dans le serveur, en général <code>conf/httpd.conf</code>.
    L'invocation d'Apache avec l'option <code>-V</code> indiquera ce nom
    comme valeur de l'étiquette <code>SERVER_CONFIG_FILE</code>. Apache
    va ensuite déterminer son <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> en effectuant les tests
    suivants, dans cet ordre </p>

    <ul>
      <li>Une directive <code>ServerRoot</code> via une option
      <code>-C</code> switch.</li>

      <li>L'option de ligne de commande <code>-d</code>.</li>

      <li>Le contenu du répertoire courant.</li>

      <li>La racine du répertoire d'installation codée en dur dans le
      serveur.</li>
    </ul>

    <p>La racine du répertoire d'installation codée en dur dans le
      serveur est en général <code>sys:/apache2</code>. L'invocation
      d'Apache avec l'option <code>-V</code> indiquera ce chemin comme
      valeur de l'étiquette <code>HTTPD_ROOT</code>.</p>

    <p>Apache 2.0 pour Netware comporte un jeu d'options de ligne de
    commande permettant d'afficher ou de modifier certaines
    caractéristiques de l'instance du serveur web en cours d'exécution.
    Ces options ne sont disponibles que lorsqu'Apache est en cours
    d'exécution. Chacune de ces options doit être précédée du mot-clé
    <code>APACHE2</code>.</p>

    <dl>
      <dt>RESTART</dt>
      <dd>Demande à Apache d'arrêter tout worker thread en cours

    </dl>

    <p>Par défaut, ces options sont passées à l'instance d'apache
    s'exécutant dans l'espace d'adressage du système d'exploitation.
    Pour passer une option à une instance d'Apache spécifique
    s'exécutant dans un espace d'adressage protégé, ajouter le paramètre
    -p suivi du nom de l'espace d'adressage. Pour plus d'informations,
    tapez "apache2 Help" sur la ligne de commande.</p>

<div class="section">
<h2><a name="use" id="use">Configuration d'Apache pour NetWare</a></h2>

    

    <p>Apache lit en général ses fichiers de configuration dans le
    répertoire <code>conf</code>. Ces fichiers sont les mêmes que ceux
    de la version Unix, mais quelques directives sont différentes sous
    Netware. Voir la <a href="../mod/">Documentation Apache</a> pour
    l'ensemble des directives disponibles.</p>

    <p>Les principales différences propres à Apache pour NetWare sont
    : </p>

    <ul>
      <li>
        <p>Comme Apache pour Netware est une application multithread,
	elle n'utilise pas de processus séparé pour chaque requête,
	comme c'est le cas pour certaines implémentations sous Unix. Il
	n'y a que des threads en cours d'exécution : un thread parent,
	et plusieurs threads enfants ou worker qui traitent les
	requêtes.</p>

        <p>En conséquence, les directives de gestion des "processus"
	sont différentes :</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code> - comme sous
	Unix, cette directive contrôle le nombre maximum de connexions
	qu'un worker thread peut traiter avant de s'arrêter. Avec la
	valeur par défaut <code>MaxConnectionsPerChild 0</code>,
	le thread va pouvoir traiter un nombre illimité de requêtes.
	Cette valeur est recommandée sous Netware, à moins que vous
	n'ayez des raisons particulières de la modifier.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code> -
	Cette directive indique au serveur le nombre de threads qu'il
	doit lancer au démarrage. Il est recommandé de conserver la
	valeur par défaut <code>StartThreads 50</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code> -
	Cette directive indique au serveur le nombre de worker threads
	additionnels qu'il doit lancer si le nombre de threads inactifs
	tombe en dessous de cette valeur. Il est recommandé de conserver la
	valeur par défaut <code>MinSpareThreads 10</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code> -
	Cette directive indique au serveur qu'il doit commencer à
	arrêter des worker threads si le nombre de threads inactifs
	passe au dessus de cette valeur. Il est recommandé de conserver
	la valeur par défaut <code>MaxSpareThreads 100</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_netware.html#maxthreads">MaxThreads</a></code> -
	Cette directive impose un nombre maximum de worker threads. Il
	est recommandé de conserver la valeur par défaut
	<code>ThreadsPerChild 250</code>.</p>

        <p><code class="directive"><a href="../mod/mpm_common.html#threadstacksize">ThreadStackSize</a></code> -
	Cette directive indique au serveur la taille de la pile à
	utiliser pour un worker thread individuel. Il est recommandé de
	conserver la valeur par défaut <code>ThreadStackSize
	65536</code>.</p>
      </li>

      <li>
        <p>Les directives qui acceptent des noms de fichiers comme
	arguments ne doivent pas utiliser des noms de fichiers Unix,
	mais des noms de fichiers Netware. Cependant, comme Apache
	utilise des noms de style Unix en interne, on doit utiliser des
	slashes et non des antislashes. Il est recommandé de préfixer
	tous les chemins de fichiers racines par un nom de volume. Si ce
	dernier est omis, Apache supposera que le volume est
	<code>SYS:</code>, ce qui n'est pas forcément correct.</p>
      </li>

      <li>
        <p>Apache pour Netware a la possibilité de charger des modules
	en cours d'exécution, sans avoir à recompiler le serveur. Si
	Apache est compilé avec les options par défaut, il va installer
	de nombreux modules optionnels dans le répertoire
	<code>\Apache2\modules</code>. Pour les activer, ou en activer
	d'autres, on doit utiliser la directive <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code>. Par exemple, pour
	activer le module status, ajoutez la ligne suivante :</p>

        <div class="example"><p><code>
          LoadModule status_module modules/status.nlm
        </code></p></div>

        <p>Des informations à propos de la  <a href="../mod/mod_so.html#creating">création de modules
	chargeables</a> sont aussi disponibles.</p>
      </li>
    </ul>

      <ul>
        <li><code class="directive"><a href="../mod/core.html#cgimapextension">CGIMapExtension</a></code> -

<h2><a name="comp" id="comp">Compilation d'Apache pour NetWare</a></h2>

    

    <p>La compilation d'Apache nécessite MetroWerks CodeWarrior 6.x ou
    supérieur. Une fois compilé, Apache peut être installé à la racine
    de tout volume Netware. Le répertoire d'installation par défaut est
    <code>sys:/Apache2</code>.</p>

    <p>Avant de démarrer Apache, vous devez remplir le répertoire
    <code>conf</code>. Copiez le fichier <code>HTTPD-STD.CONF</code>
    depuis le répertoire <code>conf</code> de la distribution et
    renommez-le en <code>HTTPD.CONF</code>. Editez le fichier
    <code>HTTPD.CONF</code> en recherchant les repères
    <code>@@Value@@</code>, et remplacez ces derniers par la valeur
    appropriée. Copiez de même les fichiers <code>conf/magic</code> et
    <code>conf/mime.types</code>. Vous pouvez aussi construire une
    distribution complète en ajoutant le mot-clé <code>install</code>
    lors de l'invocation des makefiles.</p>

    <h3><a name="comp-req" id="comp-req">Prérequis :</a></h3>

      

      <p>Les outils de développement suivants sont nécessaires pour la
      compilation d'Apache pour Netware :</p>

      <ul>
        <li>Metrowerks CodeWarrior 6.0 ou supérieur avec le <a href="http://developer.novell.com/ndk/cwpdk.htm">NetWare PDK
	3.0</a> ou supérieur.</li>

        <li>Les <a href="http://developer.novell.com/ndk/libc.htm">Bibliothèques
	Netware pour C (LibC)</a></li>

        <li>Les <a href="http://developer.novell.com/ndk/cldap.htm">Bibliothèques
	LDAP pour C</a></li>

        <li>Le <a href="http://www.gzip.org/zlib/">Code source de la
	bibliothèque de compression ZLIB</a></li>

        <li>L'utilitaire AWK (awk, gawk ou similaire). AWK peut être
	téléchargé à <a href="http://developer.novell.com/ndk/apache.htm">http://developer.novell.com/ndk/apache.htm</a>.
	L'utilitaire doit se trouver dans votre chemin windows et avoir
	pour nom <code>awk.exe</code>.</li>

        <li>Pour utiliser les makefiles, vous devez disposer de GNU make
	version 3.78.1 (GMake) disponible à <a href="http://developer.novell.com/ndk/apache.htm">http://developer.novell.com/ndk/apache.htm</a>.</li>
      </ul>

    

    <h3><a name="comp-make" id="comp-make">Compiler Apache en utilisant les makefiles Netware
      :</a></h3>

      

      <ul>
        <li>Définissez la variable d'environnement
	<code>NOVELLLIBC</code> avec le chemin des bibliothèques Netware
	pour C SDK ; par exemple : <div class="example"><p><code>Set
	NOVELLLIBC=c:\novell\ndk\libc</code></p></div></li>

        <li>Définissez la variable d'environnement
	<code>METROWERKS</code> avec le chemin de votre compilateur
	Metrowerks CodeWarrior ; par exemple : <div class="example"><p><code>Set
	METROWERKS=C:\Program Files\Metrowerks\CodeWarrior</code></p></div>. Si
	vous l'avez installé dans le répertoire par défaut
	<code>C:\Program Files\Metrowerks\CodeWarrior</code>, vous
	n'avez pas besoin de définir cette variable.</li>

        <li>Définissez la variable d'environnement <code>LDAPSDK</code>
	avec le chemin des bibliothèques LDAP pour C ; par exemple :
	<div class="example"><p><code>Set
	LDAPSDK=c:\Novell\NDK\cldapsdk\NetWare\libc</code></p></div></li>

        <li>Définissez la variable d'environnement <code>ZLIBSDK</code>
	avec le chemin du code source de la bibliothèque Zlib ; par
	exemple : <div class="example"><p><code>Set ZLIBSDK=D:\NOVELL\zlib</code></p></div></li>

	<li>Définissez la variable d'environnement <code>PCRESDK</code>
	avec le chemin d'installation du code source de la bibliothèque
	PCRE ; par exemple :
	<div class="example"><p><code>Set PCRESDK=D:\NOVELL\pcre</code></p></div>
	</li>

        <li>Définissez la variable d'environnement <code>AP_WORK</code>
	avec le chemin du code source de <code>httpd</code>.
	<div class="example"><p><code>Set AP_WORK=D:\httpd-2.0.x</code></p></div></li>

        <li>Définissez la variable d'environnement <code>APR_WORK</code>
	avec le chemin du code source d'<code>apr</code> ; en général
	<code>\httpd\srclib\apr</code>, mais le projet APR peut se
	trouver en dehors de la structure des répertoires de httpd.
	<div class="example"><p><code>Set APR_WORK=D:\apr-1.x.x</code></p></div></li>

        <li>Définissez la variable d'environnement <code>APU_WORK</code>
	avec le chemin du code source d'<code>apr-util</code> ; en
	général <code>\httpd\srclib\apr-util</code>, mais le projet
	APR-UTIL peut se trouver en dehors de la structure des
	répertoires de httpd. <div class="example"><p><code>Set
	APU_WORK=D:\apr-util-1.x.x</code></p></div></li>

        <li>Vérifiez que les chemins des utilitaires AWK et GNU make
	(<code>gmake.exe</code>) ont bien été inclus dans la variable
	d'environnement système <code>PATH</code>.</li>

        <li>Téléchargez le code source et décompressez-le dans un
	répertoire de votre choix sur votre station de travail.</li>

        <li>Positionnez-vous dans le répertoire <code>\httpd-2.0</code>
	et compilez les utilitaires précompilés à l'aide de la commande
	"<code>gmake -f nwgnumakefile prebuild</code>". Cette cible va
	créer le répertoire <code>\httpd-2.0\nwprebuild</code>, et y
	copier tous les utilitaires nécessaires au franchissement des
	étapes suivantes de la compilation.</li>

        <li>Copiez les fichiers
	<code>\httpd-2.0\nwprebuild\GENCHARS.nlm</code> et
	<code>\httpd-2.0\nwprebuild\DFTABLES.nlm</code> vers le volume
	<code>SYS:</code> d'un serveur Netware et exécutez-les à l'aide
	des commandes suivantes :
          <div class="example"><p><code>
            SYS:\genchars &gt; sys:\test_char.h<br />
            SYS:\dftables sys:\chartables.c<br />
          </code></p></div>
        </li>

        <li>Copiez les fichiers <code>test_char.h</code> et
	<code>chartables.c</code> vers le répertoire
	<code>\httpd-2.0\os\netware</code> de la machine où s'effectue
	la compilation.</li>

        <li>Positionnez-vous dans le répertoire <code>\httpd-2.0</code>
	et compilez Apache à l'aide de la commande "<code>gmake -f
	nwgnumakefile</code>". Vous pouvez créer un répertoire pour la
	distribution en ajoutant le paramètre install à la commande ;
	par exemple :
        <div class="example"><p><code>gmake -f nwgnumakefile install</code></p></div>
        </li>
      </ul>

    

    <h3><a name="comp-add" id="comp-add">Options de make supplémentaires</a></h3>

      

      <ul>
        <li><code>gmake -f nwgnumakefile</code><p>Compile les versions
	de distribution de tous les binaires et les copie dans un
	répertoire <code>\release</code>.</p></li>

        <li><code>gmake -f nwgnumakefile DEBUG=1</code><p>Compile les versions
	de débogage de tous les binaires et les copie dans un
	répertoire <code>\debug</code>.</p></li>

        <li><code>gmake -f nwgnumakefile install</code><p>Crée une
	distribution complète d'Apache avec les binaires, la
	documentation et les fichiers support dans un répertoire
	<code>\dist\Apache2</code>.</p></li>

        <li><code>gmake -f nwgnumakefile prebuild</code><p>Compile tous
	les utilitaires précompilés et les copie dans le répertoire
	<code>\nwprebuild</code>.</p></li>

        <li><code>gmake -f nwgnumakefile installdev</code><p>Même effet
	que l'option install, mais en plus, les répertoires
	<code>\lib</code> et <code>\include</code> sont créés dans le
	répertoire de destination, et les en-têtes et fichiers d'import
	y sont copiés.</p></li>

        <li><code>gmake -f nwgnumakefile clean</code><p>Supprime tous
	les fichiers objets et les binaires de la zone de compilation
	<code>\release.o</code>, ou <code>\debug.o</code> si
	<code>DEBUG</code> a été défini.</p></li>

        <li><code>gmake -f nwgnumakefile clobber_all</code><p>Même effet
	que clean, mais en plus, le répertoire de la distribution est
	supprimé s'il existe.</p></li>
      </ul>

    

    <h3><a name="comp-add-env" id="comp-add-env">Variables d'environnement supplémentaires</a></h3>

      

      <ul>
        <li>Pour compiler tous les modules expérimentaux, définissez la
	variable d'environnement <code>EXPERIMENTAL</code> :
        <div class="example"><p><code>Set EXPERIMENTAL=1</code></p></div>
        </li>

        <li>Pour compiler Apache en utilisant les sockets de style BSD
	standard, plutôt que Winsock, définissez la variable
	d'environnement <code>USE_STDSOCKETS</code> :
        <div class="example"><p><code>Set USE_STDSOCKETS=1</code></p></div>
        </li>

      </ul>

    

    <h3><a name="comp-mod_ssl" id="comp-mod_ssl">Compilation de mod_ssl pour la plate-forme Netware</a></h3>

      

      <p>Pour fournir les services SSL, Apache pour Netware utilise par
      défaut le module intégré <code class="module"><a href="../mod/mod_nw_ssl.html">mod_nw_ssl</a></code>. Ce module ne
      fournit que les services SSL implémentés par le système
      d'exploitation Netware lui-même pour gérer tous les chiffrements
      pour un port donné. Cependant, on peut aussi utiliser mod_ssl de
      la même manière que sur les autres plate-formes.</p>

      <p>Afin de pouvoir compiler mod_ssl pour la plate-forme Netware,
      les bibliothèques OpenSSL doivent être disponibles. Elles peuvent
      être installées de la manière suivante :</p>

      <ul>
          <li>Téléchargez la dernière distribution du code source
	  d'OpenSSL 0.9.8 depuis la page <a href="http://www.openssl.org/source/">OpenSSL Source</a> (les
	  versions 0.9.7 doivent être patchées, et ne sont donc pas
	  recommandées).</li>

          <li>Editez le fichier <code>NetWare/set_env.bat</code>, et
	  effectuez toutes modifications nécessaires des chemins des
	  outils et utilitaires en fonction de votre environnement de
	  développement.</li>

          <li>Exécutez les scripts suivants depuis la racine du
	  répertoire des sources d'OpenSSL :
          <div class="example"><p><code>
              Netware\set_env netware-libc<br />
              Netware\build netware-libc
          </code></p></div>
          Pour des raisons de performances, vous devez activer la
	  compilation avec le code ASM. Télécharger NASM depuis le <a href="http://nasm.sourceforge.net/">site SF</a>. Configurez
	  ensuite OpenSSL pour utiliser le code ASM :
          <div class="example"><p><code>
              Netware\build netware-libc nw-nasm enable-mdc2 enable-md5
          </code></p></div>
          Attention : n'utilisez pas l'Assembleur CodeWarrior - il
	  produit un code de mauvaise qualité !</li>

          <li>Avant de compiler Apache, définissez la variable
	  d'environnement <code>OSSLSDK</code> avec le chemin absolu de
	  la racine du répertoire du code source d'openssl, et
	  définissez WITH_MOD_SSL à 1.
          <div class="example"><p><code>
              Set OSSLSDK=d:\openssl-0.9.8x<br />
              Set WITH_MOD_SSL=1
          </code></p></div></li>

      </ul>

<h2><a name="configexample" id="configexample">Basic Configuration Example</a></h2>


<p>Your SSL configuration will need to contain, at minimum, the
following directives.</p>

<pre class="prettyprint lang-config">LoadModule ssl_module modules/mod_ssl.so

Listen 443
&lt;VirtualHost *:443&gt;
    ServerName www.example.com
    SSLEngine on
    SSLCertificateFile "/path/to/www.example.com.cert"

&lt;/VirtualHost&gt;</pre>

<h2><a name="ciphersuites" id="ciphersuites">Cipher Suites and Enforcing Strong Security</a></h2>

<ul>
<li><a href="#onlystrong">How can I create an SSL server which accepts strong encryption only?</a></li>
<li><a href="#strongurl">How can I create an SSL server which accepts all types of ciphers in general, but
requires a strong cipher for access to a particular URL?</a></li>
</ul>

<h3><a name="onlystrong" id="onlystrong">How can I create an SSL server which accepts strong encryption
only?</a></h3>

    <p>The following enables only the strongest ciphers:</p>
    <pre class="prettyprint lang-config">SSLCipherSuite HIGH:!aNULL:!MD5</pre>


    <p>While with the following configuration you specify a preference
    for specific speed-optimized ciphers (which will be selected by
    mod_ssl, provided that they are supported by the client):</p>

    <pre class="prettyprint lang-config">SSLCipherSuite RC4-SHA:AES128-SHA:HIGH:!aNULL:!MD5
SSLHonorCipherOrder on</pre>



<h3><a name="strongurl" id="strongurl">How can I create an SSL server which accepts all types of ciphers
in general, but requires a strong ciphers for access to a particular
URL?</a></h3>

    <p>Obviously, a server-wide <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code> which restricts
    ciphers to the strong variants, isn't the answer here. However,
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> can be reconfigured within <code>Location</code>
    blocks, to give a per-directory solution, and can automatically force
    a renegotiation of the SSL parameters to meet the new configuration.
    This can be done as follows:</p>
    <pre class="prettyprint lang-config"># be liberal in general
SSLCipherSuite ALL:!aNULL:RC4+RSA:+HIGH:+MEDIUM:+LOW:+EXP:+eNULL

&lt;Location "/strong/area"&gt;
# but https://hostname/strong/area/ and below
# requires strong ciphers
SSLCipherSuite HIGH:!aNULL:!MD5
&lt;/Location&gt;</pre>

<div class="section">
<h2><a name="ocspstapling" id="ocspstapling">OCSP Stapling</a></h2>


<p>The Online Certificate Status Protocol (OCSP) is a mechanism for
determining whether or not a server certificate has been revoked, and OCSP
Stapling is a special form of this in which the server, such as httpd and
mod_ssl, maintains current OCSP responses for its certificates and sends
them to clients which communicate with the server.  Most certificates
contain the address of an OCSP responder maintained by the issuing
Certificate Authority, and mod_ssl can communicate with that responder to
obtain a signed response that can be sent to clients communicating with
the server.</p>

<p>Because the client can obtain the certificate revocation status from
the server, without requiring an extra connection from the client to the
Certificate Authority, OCSP Stapling is the preferred way for the
revocation status to be obtained.  Other benefits of eliminating the 
communication between clients and the Certificate Authority are that the
client browsing history is not exposed to the Certificate Authority and
obtaining status is more reliable by not depending on potentially heavily
loaded Certificate Authority servers.</p>

<p>Because the response obtained by the server can be reused for all clients
using the same certificate during the time that the response is valid, the
overhead for the server is minimal.</p>

<p>Once general SSL support has been configured properly, enabling OCSP
Stapling generally requires only very minor modifications to the httpd
configuration — the addition of these two directives:</p>

    <pre class="prettyprint lang-config">SSLUseStapling On
SSLStaplingCache "shmcb:logs/ssl_stapling(32768)"</pre>


<p>These directives are placed at global scope (i.e., not within a virtual
host definition) wherever other global SSL configuration directives are
placed, such as in <code>conf/extra/httpd-ssl.conf</code> for normal 
open source builds of httpd, <code>/etc/apache2/mods-enabled/ssl.conf</code>
for the Ubuntu or Debian-bundled httpd, etc.</p>

<p>The path on the <code class="directive">SSLStaplingCache</code> directive
(e.g., <code>logs/</code>) should match the one on the 
<code class="directive">SSLSessionCache</code> directive.  This path is relative
to <code class="directive">ServerRoot</code>.</p>

<p>This particular <code class="directive">SSLStaplingCache</code> directive requires
<code class="module"><a href="../mod/mod_socache_shmcb.html">mod_socache_shmcb</a></code> (from the <code>shmcb</code> prefix on the
directive's argument).  This module is usually enabled already for
<code class="directive">SSLSessionCache</code> or on behalf of some module other than
<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>.  If you enabled an SSL session cache using a 
mechanism other than <code class="module"><a href="../mod/mod_socache_shmcb.html">mod_socache_shmcb</a></code>, use that alternative
mechanism for <code class="directive">SSLStaplingCache</code> as well.  For example:</p>

    <pre class="prettyprint lang-config">SSLSessionCache "dbm:logs/ssl_scache"
SSLStaplingCache "dbm:logs/ssl_stapling"</pre>


<p>You can use the openssl command-line program to verify that an OCSP response
is sent by your server:</p>

<pre>$ openssl s_client -connect www.example.com:443 -status -servername www.example.com
...
OCSP response: 
======================================
OCSP Response Data:
    OCSP Response Status: successful (0x0)
    Response Type: Basic OCSP Response
...
    Cert Status: Good
...</pre>

<p>The following sections highlight the most common situations which require
further modification to the configuration.  Refer also to the 
<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> reference manual.</p>

<h3>If more than a few SSL certificates are used for the server</h3>

<p>OCSP responses are stored in the SSL stapling cache.  While the responses
are typically a few hundred to a few thousand bytes in size, mod_ssl 
supports OCSP responses up to around 10K bytes in size.  With more than a 
few certificates, the stapling cache size (32768 bytes in the example above) 
may need to be increased.  Error message AH01929 will be logged in case of
an error storing a response.</p>


<h3>If the certificate does not point to an OCSP responder, or if a
different address must be used</h3>

<p>Refer to the 
<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingforceurl">SSLStaplingForceURL</a></code> directive.</p>

<p>You can confirm that a server certificate points to an OCSP responder
using the openssl command-line program, as follows:</p>

<pre>$ openssl x509 -in ./www.example.com.crt -text | grep 'OCSP.*http'
OCSP - URI:http://ocsp.example.com</pre>

<p>If the OCSP URI is provided and the web server can communicate to it
directly without using a proxy, no configuration is required.  Note that
firewall rules that control outbound connections from the web server may
need to be adjusted.</p>

<p>If no OCSP URI is provided, contact your Certificate Authority to
determine if one is available; if so, configure it with
<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingforceurl">SSLStaplingForceURL</a></code> in the virtual
host that uses the certificate.</p>


<h3>If multiple SSL-enabled virtual hosts are configured and OCSP
Stapling should be disabled for some</h3>


<p>Add <code>SSLUseStapling Off</code> to the virtual hosts for which OCSP
Stapling should be disabled.</p>


<h3>If the OCSP responder is slow or unreliable</h3>

<p>Several directives are available to handle timeouts and errors.  Refer
to the documentation for the
<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingfaketrylater">SSLStaplingFakeTryLater</a></code>,
<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingrespondertimeout">SSLStaplingResponderTimeout</a></code>, and
<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingreturnrespondererrors">SSLStaplingReturnResponderErrors</a></code>
directives.</p>


<h3>If mod_ssl logs error AH02217</h3>

<pre>AH02217: ssl_stapling_init_cert: Can't retrieve issuer certificate!</pre>
<p>In order to support OCSP Stapling when a particular server certificate is
used, the certificate chain for that certificate must be configured.  If it 
was not configured as part of enabling SSL, the AH02217 error will be issued

<h3><a name="allclients" id="allclients">How can I force clients to authenticate using certificates?</a></h3>


    <p>When you know all of your users (eg, as is often the case on a corporate
    Intranet), you can require plain certificate authentication. All you
    need to do is to create client certificates signed by your own CA
    certificate (<code>ca.crt</code>) and then verify the clients against this
    certificate.</p>
    <pre class="prettyprint lang-config"># require a client certificate which has to be directly
# signed by our CA certificate in ca.crt
SSLVerifyClient require
SSLVerifyDepth 1
SSLCACertificateFile "conf/ssl.crt/ca.crt"</pre>



<h3><a name="arbitraryclients" id="arbitraryclients">How can I force clients to authenticate using certificates for a
  particular URL, but still allow arbitrary clients to access the rest of the server?</a></h3>


    <p>To force clients to authenticate using certificates for a particular URL,
    you can use the per-directory reconfiguration features of
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>:</p>

    <pre class="prettyprint lang-config">SSLVerifyClient none
SSLCACertificateFile "conf/ssl.crt/ca.crt"

&lt;Location "/secure/area"&gt;
SSLVerifyClient require
SSLVerifyDepth 1
&lt;/Location&gt;</pre>



<h3><a name="certauthenticate" id="certauthenticate">How can I allow only clients who have certificates to access a
  particular URL, but allow all clients to access the rest of the server?</a></h3>


    <p>The key to doing this is checking that part of the client certificate
    matches what you expect. Usually this means checking all or part of the
    Distinguished Name (DN), to see if it contains some known string.
    There are two ways to do this, using either <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
    <code class="directive"><a href="../mod/mod_ssl.html#sslrequire">SSLRequire</a></code>.</p>

    <p>The <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> method is generally required when
    the certificates are completely arbitrary, or when their DNs have
    no common fields (usually the organisation, etc.). In this case,
    you should establish a password database containing <em>all</em>
    clients allowed, as follows:</p>

    <pre class="prettyprint lang-config">SSLVerifyClient      none
SSLCACertificateFile "conf/ssl.crt/ca.crt"
SSLCACertificatePath "conf/ssl.crt"

&lt;Directory "/usr/local/apache2/htdocs/secure/area"&gt;
    SSLVerifyClient      require
    SSLVerifyDepth       5
    SSLOptions           +FakeBasicAuth
    SSLRequireSSL
    AuthName             "Snake Oil Authentication"
    AuthType             Basic
    AuthBasicProvider    file
    AuthUserFile         "/usr/local/apache2/conf/httpd.passwd"
    Require              valid-user
&lt;/Directory&gt;</pre>


    <p>The password used in this example is the DES encrypted string "password".
    See the <code class="directive"><a href="../mod/mod_ssl.html#ssloptions">SSLOptions</a></code> docs for more
    information.</p>

    <div class="example"><h3>httpd.passwd</h3><pre>/C=DE/L=Munich/O=Snake Oil, Ltd./OU=Staff/CN=Foo:xxj31ZMTZzkVA
/C=US/L=S.F./O=Snake Oil, Ltd./OU=CA/CN=Bar:xxj31ZMTZzkVA
/C=US/L=L.A./O=Snake Oil, Ltd./OU=Dev/CN=Quux:xxj31ZMTZzkVA</pre></div>

    <p>When your clients are all part of a common hierarchy, which is encoded
    into the DN, you can match them more easily using <code class="directive"><a href="../mod/mod_ssl.html#sslrequire">SSLRequire</a></code>, as follows:</p>


    <pre class="prettyprint lang-config">SSLVerifyClient      none
SSLCACertificateFile "conf/ssl.crt/ca.crt"
SSLCACertificatePath "conf/ssl.crt"

&lt;Directory "/usr/local/apache2/htdocs/secure/area"&gt;
  SSLVerifyClient      require
  SSLVerifyDepth       5
  SSLOptions           +FakeBasicAuth
  SSLRequireSSL
  SSLRequire       %{SSL_CLIENT_S_DN_O}  eq "Snake Oil, Ltd." \
               and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"}
&lt;/Directory&gt;</pre>



<h3><a name="intranet" id="intranet">How can I require HTTPS with strong ciphers, and either basic
authentication or client certificates, for access to part of the
Intranet website, for clients coming from the Internet? I still want to allow
plain HTTP access for clients on the Intranet.</a></h3>


   <p>These examples presume that clients on the Intranet have IPs in the range
   192.168.1.0/24, and that the part of the Intranet website you want to allow
   internet access to is <code>/usr/local/apache2/htdocs/subarea</code>.
   This configuration should remain outside of your HTTPS virtual host, so
   that it applies to both HTTPS and HTTP.</p>

    <pre class="prettyprint lang-config">SSLCACertificateFile "conf/ssl.crt/company-ca.crt"

&lt;Directory "/usr/local/apache2/htdocs"&gt;
    #   Outside the subarea only Intranet access is granted
    Require              ip 192.168.1.0/24
&lt;/Directory&gt;

&lt;Directory "/usr/local/apache2/htdocs/subarea"&gt;
    #   Inside the subarea any Intranet access is allowed
    #   but from the Internet only HTTPS + Strong-Cipher + Password
    #   or the alternative HTTPS + Strong-Cipher + Client-Certificate
    
    #   If HTTPS is used, make sure a strong cipher is used.
    #   Additionally allow client certs as alternative to basic auth.
    SSLVerifyClient      optional
    SSLVerifyDepth       1
    SSLOptions           +FakeBasicAuth +StrictRequire
    SSLRequire           %{SSL_CIPHER_USEKEYSIZE} &gt;= 128
    
    #   Force clients from the Internet to use HTTPS
    RewriteEngine        on
    RewriteCond          "%{REMOTE_ADDR}" "!^192\.168\.1\.[0-9]+$"
    RewriteCond          "%{HTTPS}" "!=on"
    RewriteRule          "." "-" [F]
    
    #   Allow Network Access and/or Basic Auth
    Satisfy              any

<p>Ce chapitre en guise d'introduction est destiné aux lecteurs pour lesquels
le Web, HTTP et Apache sont familiers, mais ne sont pas des experts en matière
de sécurité. Il n'a pas la prétention d'être un guide détaillé sur le
protocole SSL, il ne traitera pas non plus des techniques spécifiques de gestion
des certificats dans une organisation, ni des importants problèmes légaux de
brevets ou des restrictions d'importation ou d'exportation. Il se veut plutôt
une base de travail pour les utilisateurs de <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> en
rassemblant différents concepts, définitions et exemples comme point de départ
pour une exploration plus détaillée.</p>

<h2><a name="cryptographictech" id="cryptographictech">Techniques de chiffrement</a></h2>

<p>La maîtrise de SSL nécessite la compréhension des algorithmes de
chiffrement, des fonctions relatives aux empreintes de messages (comme les
fonctions de type hash ou non réversibles), et des signatures numériques. Ces
techniques pourraient faire l'objet d'un ouvrage à elles seules (voir par
exemple [<a href="#AC96">AC96</a>]) et constituent les bases de la
confidentialité, de l'intégrité et de l'authentification.</p>

<h3><a name="cryptographicalgo" id="cryptographicalgo">Algorithmes de chiffrement</a></h3>

    <p>Supposons qu'Alice veuille envoyer un message à sa banque pour
    transférer une certaine somme. Alice souhaiterait que le message soit
    privé, car il contient des informations comme son numéro de compte et le
    montant du transfert. Une solution consisterait à utiliser un algorithme de
    chiffrement, technique qui permet de remplacer un message par sa version
    chiffrée, illisible jusqu'à ce qu'elle soit déchiffrée.
    Sous sa forme chiffrée,
    le message ne peut être déchiffré qu'en utilisant une clé secrète. Sans la
    clé, le message est inutilisable : les bons algorithmes de chiffrement
    rendent si difficile la restitution du texte original par des intrus que
    ceux-ci y gaspilleraient leurs efforts.</p>

    <p>Il existe deux catégories d'algorithmes de chiffrement : conventionnel
    ou à clé publique.</p>

    <dl>
    <dt>Chiffrement conventionnel</dt>
    <dd>aussi connu sous le nom de chiffrement symétrique, il nécessite le
    partage d'une clé entre l'expéditeur et le destinataire : une portion
    d'information secrète permettant de chiffrer et déchiffrer un message.
    Tant que cette clé reste secrète, personne à part l'expéditeur et le
    destinataire ne peut lire le message. Si Alice et sa banque partagent une
    clé secrète, ils peuvent donc s'envoyer l'un à l'autre des messages privés.
    Le fait de partager une clé entre l'expéditeur et le destinataire avant
    de communiquer, tout en la maintenant secrète vis à vis des autres, peut
    toutefois poser des problèmes.</dd>

    <dt>Chiffrement à clé publique</dt>
    <dd>aussi connu sous le nom de chiffrement asymétrique, il résoud le
    problème d'échange de clé en définissant un algorithme qui utilise deux
    clés, chacune d'entre elles pouvant être utilisée pour chiffrer un message.
    Si une des clés a été utilisée pour chiffrer le message, on doit utiliser
    l'autre clé pour le déchiffrer. Il est ainsi possible de recevoir des
    messages sécurisés simplement en rendant publique une des clés (la clé
    publique), et en gardant l'autre clé secrète (la clé privée).</dd>
    </dl>

    <p>Tout le monde peut chiffrer un message en utilisant la clé publique,
    mais seul le propriétaire de la clé privée sera en mesure de le lire. De
    cette façon, Alice peut envoyer des messages privés au propriétaire d'une
    paire de clés (sa banque), en les chiffrant à l'aide de la clé publique.
    Seule la banque sera en mesure de les déchiffrer.</p>


<h3><a name="messagedigests" id="messagedigests">Empreinte d'un message</a></h3>

    <p>Bien qu'Alice puisse chiffrer son message pour le rendre privé, il
    subsiste toujours le risque que quelqu'un puisse modifier le message
    original ou le remplacer par un autre, afin d'effectuer le transfert de
    fonds à son profit, par exemple. Une solution pour garantir l'intégrité du
    message consisterait pour Alice à créer un résumé concentré de son message
    qu'elle enverrait à sa banque avec ce dernier. A la réception du message,
    la banque crée son propre résumé et le compare avec celui qu'Alice a
    envoyé. Si les deux résumés sont identiques, le message reçu n'a pas
    été modifié.</p>

    <p>Un résumé tel que celui-ci est appelé
    <dfn>empreinte numérique de message</dfn> (message digest),
    <em>fonction irréversible</em> (one-way function) ou
    <em>fonction de hashage</em> (hash function). Une empreinte de message
    constitue une représentation courte et de longueur fixe, d'un message plus
    long et de longueur variable. Les algorithmes de création d'empreintes sont
    conçus pour produire une empreinte unique pour chaque message. Les
    empreintes de messages sont conçues pour que la restitution du message
    à partir de l'empreinte soit d'une difficulté insurmontable, et qu'il soit
    (en théorie) impossible de trouver deux messages différents qui produisent
    la même empreinte -- ce qui élimine la possibilité de remplacer un message
    par un autre en conservant la même empreinte.</p>

    <p>Trouver le moyen d'envoyer l'empreinte de manière sécurisée à la banque
    constitue un autre défit auquel Alice doit faire face ; si l'empreinte
    n'est pas envoyée de manière sécurisée, son intégrité peut être compromise,
    et avec elle, la possibilité pour la banque de vérifier l'intégrité du
    message original. L'intégrité du message ne peut être vérifiée que si
    l'empreinte qui lui est associée est envoyée de manière sécurisée.</p>

    <p>Une solution pour envoyer l'empreinte de manière sécurisée consiste à
    l'inclure dans une signature numérique.</p>


<h3><a name="digitalsignatures" id="digitalsignatures">Signatures numériques</a></h3>
<p>Quand Alice envoie un message à sa banque, cette dernière doit s'assurer
que le message a bien été envoyé par elle, pour éviter qu'un intrus puisse
effectuer une transaction sur son compte. Une <em>signature numérique</em>,
créée par Alice et incluse dans le message, permet d'atteindre cet
objectif.</p>

<p>Les signatures numériques peuvent être créées en chiffrant une empreinte de
message, ainsi que d'autres informations (comme un numéro d'ordre) avec la clé
privée de l'expéditeur. Bien que tout le monde puisse <em>déchiffrer</em> la
signature à l'aide de la clé publique, seul l'expéditeur connait la clé privée.
Ce qui implique que seul l'expéditeur peut avoir signé le message. Inclure
l'empreinte dans la signature entraîne que cette dernière n'est valable que
pour ce message ; ceci assure aussi l'intégrité du message car personne ne
peut modifier l'empreinte et ensuite signer le message.</p>
<p>Afin de se prémunir contre l'interception et la réutilisation de la
signature par un intrus quelques jours plus tard, la signature contient un
numéro d'ordre unique. Ceci protège la banque contre une plainte frauduleuse
de la part d'Alice alléguant qu'elle n'a pas envoyé le message --
elle seule peut l'avoir signé (non-répudiation).</p>


</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="certificates" id="certificates">Certificats</a></h2>

<p>Bien qu'Alice soit parvenue à envoyer un message privé à sa banque, après
l'avoir signé et avoir ainsi assuré l'intégrité du message, elle doit encore vérifier
qu'elle communique réellement avec la banque. C'est à dire qu'elle doit
s'assurer que la clé publique qu'elle utilise appartient bien à la paire de
clés de la banque, et non à celle d'un intrus.
De même, la banque doit vérifier que la
signature du message a bien été construite avec la clé privée d'Alice.</p>

<p>Si chaque partie possède un certificat qui valide l'identité de l'autre,
confirme la clé publique, et est signé par un organisme de confiance, alors
les deux protagonistes peuvent être sûrs que la personne avec laquelle ils
communiquent est bien celle avec laquelle ils désirent le faire. Un tel
organisme de confiance s'appelle une <em>Autorité de Certification</em>, et
on utilise les certificats à des fins d'authentification.</p>

<h3><a name="certificatecontents" id="certificatecontents">Contenu d'un certificat</a></h3>

    <p>Un certificat associe une clé publique avec l'identité réelle d'un
    individu, d'un serveur, ou d'une autre entité plus connue sous le nom de
    sujet. Comme on le voit dans le <a href="#table1">Tableau 1</a>, les
    information concernant le sujet comprennent des informations
    d'identification (le nom distinctif ou distinguished name - dn), ainsi que
    la clé publique. Il comporte aussi l'identification et la signature de
    l'autorité de certification qui a délivré le certificat, ainsi que la
    période de validité de ce dernier. Il peut aussi contenir des informations
    supplémentaires (ou extensions) telles que des informations de gestion
    destinées à l'autorité de certification, comme un numéro de série.</p>

    <h4><a name="table1" id="table1">Tableau 1: Information contenues dans un certificat</a></h4>
    
    <table>
    
    <tr><th>Sujet</th>
        <td>Nom distinctif, Clé publique</td></tr>
    <tr><th>Fournisseur</th>
        <td>Nom distinctif, Signature</td></tr>
    <tr><th>Période de validité</th>
        <td>Pas avant, Pas après</td></tr>
    <tr><th>Informations de gestion</th>
        <td>Version, Numéro de série</td></tr>
    <tr><th>Extensions</th>
        <td>Contraintes de base, Drapeaux Netscape, etc.</td></tr>
    </table>
    

    <p>Un nom distinctif sert à fournir une identité dans un contexte
    spécifique -- par exemple, un individu peut posséder un certificat
    personnel, et aussi un certificat en tant qu'employé. Les noms distinctifs
    doivent respecter le standard X509 [<a href="#X509">X509</a>], qui définit
    les champs, les noms de champs, et les abréviations utilisées pour faire
    référence aux champs (voir <a href="#table2">Tableau 2</a>).</p>

    <h4><a name="table2" id="table2">Tableau 2: Informations contenues dans le nom distinctif</a></h4>
    
    <table class="bordered">
    
    <tr><th>Champ du DN</th>
        <th>Abrév.</th>
        <th>Description</th>
        <th>Exemple</th></tr>
    <tr><td>Nom complet (Common Name)</td>
        <td>CN</td>
        <td>Nom certifié</td>
        <td>CN=Joe Average</td></tr>
    <tr><td>Organisation or Entreprise</td>
        <td>O</td>
        <td>Nom est associé à cette<br />organisation</td>
        <td>O=Snake Oil, Ltd.</td></tr>
    <tr><td>Unité organisationnelle (Organizational Unit)</td>
        <td>OU</td>
        <td>Nom est associé avec cette <br />unité organisationnelle,
	par exemple un département</td>
        <td>OU=Research Institute</td></tr>
    <tr><td>Ville/Localisation</td>
        <td>L</td>
        <td>Nom est localisé dans cette ville</td>
        <td>L=Snake City</td></tr>
    <tr><td>Etat/Province</td>
        <td>ST</td>
        <td>Nom est localisé dans cet état/province</td>
        <td>ST=Desert</td></tr>
    <tr><td>Pays</td>
        <td>C</td>
        <td>Nom est localisé dans ce pays (code ISO)</td>
        <td>C=XZ</td></tr>
    </table>
    

    <p>Une autorité de certification peut définir une contrainte spécifiant
    quels champs du nom distinctif sont optionnels et lesquels sont
    obligatoires. Elle peut aussi imposer des contraintes sur le contenu des
    champs, ce que peuvent aussi faire les utilisateurs de certificats. Par
    exemple, un navigateur Netscape peut exiger, dans le cas d'un certificat
    de serveur, que le nom complet (Common Name) corresponde à un nom générique
    contenant le nom de domaine du serveur, comme
    <code>*.snakeoil.com</code>.</p>

    <p>Le format binaire d'un certificat est défini en utilisant la
    notation ASN.1 [<a href="#ASN1">ASN1</a>] [<a href="#PKCS">PKCS</a>].
    Cette notation definit la manière de spécifier les contenus, et les règles
    d'encodage définissent la manière dont ces information sont converties au
    format binaire. L'encodage binaire du certificat est défini par les Règles
    d'Encodage Distinctives (Distinguished Encoding Rules - DER), qui se basent
    d'une manière plus générale sur les Règles d'Encodage de Base (Basic
    Encoding Rules - BER). Pour les transmissions qui ne supportent pas le
    format binaire, ce dernier peut être converti au format ASCII en utilisant
    le codage Base64 [<a href="#MIME">MIME</a>]. Lorsqu'il est placé entre des
    délimiteurs de début et de fin (comme ci-dessous), on dit que le certificat
    est encodé au format PEM ("Privacy Enhanced Mail").</p>

<h3><a name="certificateauthorities" id="certificateauthorities">Autorités de certification</a></h3>

    <p>En vérifiant les informations contenues dans une demande de certificat
    avant de l'accorder, l'autorité de certification s'assure de l'identité du
    propriétaire de la clé privée issue de sa paire de clés. Par exemple, Si
    Alice demande un certificat personnel, l'autorité de certification doit
    d'abord s'assurer qu'elle correspond vraiment à la personne à laquelle
    la demande de certificat fait référence.</p>

    <h4><a name="certificatechains" id="certificatechains">Chaînes de certification</a></h4>
    
        <p>Une autorité de certification peut aussi émettre un certificat à
	destination d'une
	autre autorité de certification. Pour vérifier un certificat, Alice
	peut être amenée à vérifier le certificat de l'émetteur pour chaque
	autorité de certification parente, jusqu'à ce qu'elle en atteigne une
	en qui elle a confiance. Elle peut aussi ne faire confiance qu'aux
	certificats faisant l'objet d'une chaîne limitée d'émetteurs, afin
	de réduire le risque de rencontrer un "mauvais" certificat dans la
	chaîne.</p>
    

    <h4><a name="rootlevelca" id="rootlevelca">Création d'une autorité de certification racine</a></h4>
    
        <p>Comme indiqué plus haut, chaque certificat nécessite la validation
	de l'identité du sujet par un émetteur de certificats
	de niveau supérieur, et ceci en
	remontant jusqu'à l'Autorité de Certification (CA) racine. Ceci pose un
	problème : qui va se porter garant du certificat de l'autorité racine
	qui ne possède pas d'émetteur de certificat ? C'est uniquement dans ce
	cas que le certificat est auto-signé, l'émetteur du certificat et son
	sujet étant confondus. Les navigateurs sont préconfigurés avec une
	liste d'autorités de certification de confiance, mais il est important
	d'être extrèmement prudent avant de faire confiance à un certificat
	auto-signé. La large publication d'une clé publique par l'autorité
	racine réduit cependant les risques encourus
	en faisant confiance à cette clé --
	si quelqu'un publiait une clé en se faisant passer pour l'autorité, il
	serait vite démasqué.</p>

        <p>Quelques compagnies, comme <a href="http://www.thawte.com/">Thawte</a> et <a href="http://www.verisign.com/">VeriSign</a>,
	se sont proclamées elles-mêmes Autorités de Certification. Ces
	compagnies proposent les services suivant :</p>

        <ul>
        <li>Vérification des demandes de certificats</li>
        <li>Traitement des demandes de certificats</li>
        <li>Emission et gestion des certificats</li>
        </ul>

        <p>Vous pouvez aussi créer votre propre autorité de certification. Bien
	que risqué dans l'environnement de l'Internet, ceci peut s'avérer utile
	dans un Intranet, où l'organisme peut vérifier facilement les identités
	des individus et des serveurs.</p>
    

    <h4><a name="certificatemanagement" id="certificatemanagement">Gestion des certificats</a></h4>
    
        <p>Constituer une autorité de certification représente une
	responsabilité qui nécessite une solide infrastructure administrative,
	technique et gestionnaire. Les autorités de certification ne se
	contentent pas d'émettre des certificats, elles doivent aussi les gérer
	-- à savoir elles déterminent leur durée de validité, elles les
	renouvellent, et elles maintiennent des listes de certificats qui ont
	été émis dans le passé mais ne sont plus valides (Listes de révocations
	de certificats, ou CRLs).</p>

        <p>Par exemple, si Alice est titulaire d'un certificat en tant
	qu'employée d'une compagnie, mais vient de quitter cette compagnie,
	son certificat doit être révoqué. Comme les certificats ne sont émis
	qu'après vérification de l'identité du sujet, et peuvent être envoyés
	à tous ceux avec lesquels le sujet peut communiquer, il est impossible
	de discerner à partir du seul certificat s'il a été révoqué. Pour
	vérifier la validité d'un certificat, il est donc nécessaire de
	contacter l'autorité de certification qui l'a émis afin de pouvoir
	consulter ses listes de révocations de certificats -- ce qui n'est
	en général pas une partie automatique du processus.</p>

        <div class="note"><h3>Note</h3>
        <p>Si votre autorité de certification ne fait pas partie de la liste
	des autorités de confiance de votre navigateur, il faut enregistrer le
	certificat de l'autorité de certification dans ce dernier, ce qui lui
	permettra de valider les certificats de serveurs signés par cette
	autorité de certification. Ceci peut être dangereux, car une fois le
	certificat enregistré, le navigateur acceptera tous les certificats
	signés par cette autorité de certification.</p>

<h2><a name="ssl" id="ssl">Couche Points d'Accès Sécurisés - Secure Sockets Layer (SSL)</a></h2>

<p>Le protocole Couche Points d'Accès Sécurisés est une couche protocolaire
qui pourrait s'intercaler entre un protocole d'une couche réseau orientée
connexion (comme TCP/IP) et une couche protocolaire d'application (comme HTTP).
SSL fournit une communication sécurisée entre client et serveur en permettant
l'authentification mutuelle, l'utilisation des signatures numériques pour la
vérification de l'intégrité des données, et le chiffrement pour la
confidentialité.</p>

<p>Ce protocole est conçu pour supporter un grand choix d'algorithmes
spécifiques utilisés pour la cryptographie, les empreintes et les signatures.
Ceci permet la sélection d'un algorithme pour des serveurs spécifiques en
respectant la légalité, les règles d'exportation ou autres contraintes, et
permet aussi au protocole de tirer parti des nouveaux algorithmes. Ces choix
font l'objet d'une négociation entre client et serveur lors de
l'établissement de la session protocolaire.</p>

<p>Il existe plusieurs versions du protocole SSL, comme le montre le
<a href="#table4">Tableau 4</a>. Comme indiqué dans ce dernier, un des apports
de SSL 3.0 est le support du chargement des chaînes de certification. Cette
fonctionnalité permet à un serveur de passer au navigateur un certificat de
serveur accompagné du certificat de l'émetteur. Le chargement de la
chaîne permet aussi au navigateur de valider le certificat du serveur, même si
les certificats de l'autorité de certification ne sont pas installés pour les
émetteurs intermédiaires, car ils sont inclus dans la chaîne de certification.
SSL 3.0 sert de base au standard du protocole Sécurité de la Couche Transport
ou Transport Layer Security
[<a href="#TLS1">TLS</a>], actuellement en développement au sein de
l'Internet Engineering Task Force (IETF).</p>

<h3><a name="session" id="session">Etablissement d'une session</a></h3>

    <p>La session SSL est établie en suivant une séquence d'échanges
    d'informations entre client et serveur, comme le montre la
    <a href="#figure1">Figure 1</a>. Cette séquence peut varier, selon que
    le serveur est configuré pour fournir un certificat de serveur ou
    réclame un certificat client. Bien que dans certains cas, des étapes
    d'échanges d'informations supplémentaires soient nécessaires pour la
    gestion des informations de chiffrement, cet article résume un scénario
    courant. Se reporter aux spécifications SSL pour avoir la liste de
    toutes les possibilités.</p>

    <div class="note"><h3>Note</h3>
    <p>Une fois la session SSL établie, elle peut être réutilisée. Ceci
    permet d'éviter la perte de performances due à la répétition des nombreuses
    étapes nécessaires à l'établissement d'une session. Pour parvenir à ceci,
    le serveur assigne un identifiant de session unique à chaque session SSL ;
    cet identifiant est mis en cache dans le serveur et le client peut
    l'utiliser pour des connexions ultérieures afin de réduire la durée des
    échanges d'informations (et ceci jusqu'à ce que l'identifiant de session
    arrive à expiration dans le cache du serveur).</p>
    </div>

    <p class="figure">
    <img src="../images/ssl_intro_fig1.gif" alt="" width="423" height="327" /><br />
    <a id="figure1" name="figure1"><dfn>Figure 1</dfn></a> : Séquence
    simplifiée d'échanges d'informations SSL</p>

    <p>Les éléments de la séquence d'échanges d'informations, tels qu'ils
    sont utilisés par le client et le serveur, sont énumérés ci-après :</p>

    <ol>
    <li>Négociation de la suite de chiffrement à utiliser durant le transfert des données</li>
    <li>Elaboration et échange d'une clé de session entre le client et le serveur</li>
    <li>Authentification éventuelle du serveur par le client</li>
    <li>Authentification éventuelle du client par le serveur</li>
    </ol>

    <p>La première étape, la négociation de la suite de chiffrement, permet au
    client et au serveur de choisir une suite de chiffrement qu'ils supportent
    tous les deux. La spécification du protocole SSL 3.0 définit 31 suites de
    chiffrement. Une suite de chiffrement se compose des éléments
    suivants :</p>

    <ul>
    <li>Méthode d'échange de la clé</li>
    <li>Chiffrement du transfert des données</li>
    <li>Empreinte du message servant à créer le code d'authentification du
    message (MAC)</li>
    </ul>

    <p>Ces trois éléments sont décrits dans les sections suivantes.</p>


<h3><a name="keyexchange" id="keyexchange">Méthode d'échange de la clé</a></h3>

    <p>La méthode d'échange de la clé définit la manière
    dont la clé de chiffrement
    symétrique secrète et partagée utilisée pour le transfert des données de
    l'application sera acceptée par le client et le serveur. SSL 2.0 utilise
    l'échange de clé RSA seulement, tandis que SSL 3.0 supporte tout un choix
    d'algorithmes d'échange de clé incluant l'échange de clé RSA (quand les
    certificats sont utilisés), et l'échange de clés Diffie-Hellman (pour
    échanger des clés sans certificat, ou en l'absence de communication
    préalable entre le client et le serveur).</p>

    <p>Les signatures numériques constituent une variante dans le choix des
    méthodes d'échange de clé -- utiliser les signatures ou pas, et dans
    l'affirmative, quel genre de signatures utiliser. La signature à l'aide
    d'une clé privée fournit une protection contre une attaque
    "man-in-the-middle" au cours de laquelle
    l'échange d'informations destiné à générer la
    clé partagée peut être intercepté [<a href="#AC96">AC96</a>, p516].</p>


<h3><a name="ciphertransfer" id="ciphertransfer">Chiffrement du transfert de données</a></h3>

    <p>Comme décrit plus haut, SSL utilise le chiffrement symétrique
    conventionnel pour chiffrer les messages au cours d'une session. Il existe
    neuf choix possibles pour le chiffrement, y compris l'option du transfert
    non chiffré :</p>

    <ul>
    <li>Pas de chiffrement</li>
    <li>Chiffrement en continu (Stream Ciphers)
        <ul>
        <li>RC4 avec clés de 40 bits</li>
        <li>RC4 avec clés de 128 bits</li>
        </ul></li>
    <li>Chiffrement par blocs CBC (CBC Block Ciphers)
        <ul><li>RC2 avec clé de 40 bits</li>
        <li>DES avec clé de 40 bits</li>
        <li>DES avec clé de 56 bits</li>
        <li>Triple-DES avec clé de 168 bits</li>
        <li>Idea (clé de 128 bits)</li>
        <li>Fortezza (clé de 96 bits)</li>
        </ul></li>
    </ul>

    <p>"CBC" signifie Cipher Block Chaining (Chaînage de blocs chiffrés),
    c'est à dire qu'une portion du bloc de texte chiffré précédent est utilisée
    pour le chiffrement du bloc courant. "DES" signifie Data Encryption
    Standard (Standard de Chiffrement des Données)
    [<a href="#AC96">AC96</a>, ch12], et possède de nombreuses variantes
    (telles que DES40 et 3DES_EDE). Parmi les algorithmes disponibles, "Idea"
    est actuellement un des meilleurs et des plus puissants sur le plan
    cryptographique, et "RC2" est un algorithme propriétaire de RSA DSI
    [<a href="#AC96">AC96</a>, ch13].</p>


<h3><a name="digestfunction" id="digestfunction">Fonction de création d'empreinte</a></h3>

    <p>Le choix d'une fonction de création d'empreinte détermine la manière
    dont une empreinte est créée à partir d'une unité de données. SSL supporte
    les fonctions suivantes :</p>

    <ul>
    <li>Pas d'empreinte (choix Null)</li>
    <li>MD5, une empreinte de 128 bits</li>
    <li>Algorithme d'Empreinte Sécurisée (Secure Hash Algorithm - SHA-1), une
    empreinte de 160 bits</li>
    </ul>

    <p>On utilise l'empreinte de message pour créer un Code d'Authentification
    de Message (Message Authentication Code - MAC) qui est chiffré avec le
    message afin de vérifier son intégrité et de se protéger contre les
    attaques de type "rejeu".</p>


<h3><a name="handshake" id="handshake">Protocole de la séquence d'échanges d'informations</a></h3>

    <p>La séquence d'échanges d'informations utilise trois protocoles :</p>

    <ul>
    <li>Le <dfn>Protocole d'échanges d'informations SSL</dfn> pour établir
    la session SSl entre le client et le serveur.</li>
    <li>Le <dfn>Protocole de spécification du chiffrement SSL</dfn> pour
    l'agrément effectif de la suite de chiffrement à utiliser
    pour la session.</li>
    <li>Le <dfn>Protocole d'alertes SSL</dfn> pour la transmission de
    messages d'erreur SSL entre le client et le serveur.</li>
    </ul>

    <p>Ces protocoles, ainsi que les données du protocole de l'application,
    sont encapsulés dans le <dfn>Protocole d'enregistrement SSL
    (SSL Record Protocol)</dfn>, comme
    le montre la <a href="#figure2">Figure 2</a>. Un protocole encapsulé est
    tranféré en tant que données par le protocole de la couche de niveau
    inférieur, qui ne se préoccupe pas du contenu des données. Le protocole
    encapsulé n'a aucune connaissance du protocole sous-jacent.</p>

    <p class="figure">
    <img src="../images/ssl_intro_fig2.gif" alt="" width="428" height="217" /><br />
    <a id="figure2" name="figure2"><dfn>Figure 2</dfn></a>:
    Pile du protocole SSL</p>

    <p>L'encapsulation des protocoles de contrôle SSL dans le protocole
    d'enregistrement signifie que si une session active est renégociée, les
    protocoles de contrôle seront transmis de manière sécurisée. S'il n'y
    avait pas de session préalable, la suite de chiffrement Null est utilisée,
    ce qui signifie que les messages ne seront pas chiffrés et ne possèderont
    pas d'empreinte d'intégrité, jusqu'à ce que la session ait été établie.</p>


<h3><a name="datatransfer" id="datatransfer">Transmission des données</a></h3>

    <p>Le protocole d'enregistrement SSL, comme le montre la
    <a href="#figure3">Figure 3</a>, est utilisé pour transmettre les données
    de l'application et les données de contrôle SSL entre le client et le
    serveur, les données étant nécessairement fragmentées en éléments plus
    petits, ou plusieurs messages de données avec protocole de niveau
    supérieur pouvant être combinés en un seul élément. Ce protocole peut
    joindre des signatures d'empreintes, compresser et chiffrer ces éléments
    avant de les transmettre en utilisant le protocole fiable de transport
    sous-jacent (Note : actuellement, aucune implémentation majeure de SSL
    n'inclut le support de la compression).</p>

    <p class="figure">
    <img src="../images/ssl_intro_fig3.gif" alt="" width="423" height="323" /><br />
    <a id="figure3" name="figure3"><dfn>Figure 3</dfn></a>:
    Protocole d'enregistrement SSL</p>


<h3><a name="securehttp" id="securehttp">Sécurisation des communications HTTP</a></h3>

    <p>Une des utilisations courantes de SSL est la sécurisation des
    communication HTTP sur le Web entre un navigateur et un serveur web. Ceci
    n'exclut pas l'utilisation de HTTP non sécurisé - la version sécurisée
    (appelée HTTPS) est identique à du vrai HTTP sur SSL,
    mais utilise le préfixe
    d'URL <code>https</code> au lieu de <code>http</code>, et un port
    de serveur différent (par défaut le port 443).
    Ceci constitue pour une large part
    ce qu'apporte <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> au serveur web Apache.</p>

<h3><a name="mutex" id="mutex">Why do I get permission errors related to
        SSLMutex when I start Apache?</a></h3>
    <p>Errors such as ``<code>mod_ssl: Child could not open
    SSLMutex lockfile /opt/apache/logs/ssl_mutex.18332 (System error follows)
    [...] System: Permission denied (errno: 13)</code>'' are usually
    caused by overly restrictive permissions on the <em>parent</em> directories.
    Make sure that all parent directories (here <code>/opt</code>,
    <code>/opt/apache</code> and <code>/opt/apache/logs</code>) have the x-bit
    set for, at minimum, the UID under which Apache's children are running (see
    the <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code> directive).</p>


<h3><a name="entropy" id="entropy">Why does mod_ssl stop with the error
        "Failed to generate temporary 512 bit RSA private key" when I start
        Apache?</a></h3>
    <p>Cryptographic software needs a source of unpredictable data
    to work correctly. Many open source operating systems provide
    a "randomness device" that serves this purpose (usually named
    <code>/dev/random</code>). On other systems, applications have to
    seed the OpenSSL Pseudo Random Number Generator (PRNG) manually with
    appropriate data before generating keys or performing public key
    encryption. As of version 0.9.5, the OpenSSL functions that need
    randomness report an error if the PRNG has not been seeded with
    at least 128 bits of randomness.</p>
    <p>To prevent this error, <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> has to provide
    enough entropy to the PRNG to allow it to work correctly. This can
    be done via the <code class="directive"><a href="../mod/mod_ssl.html#sslrandomseed">SSLRandomSeed</a></code>
    directive.</p>

<h3><a name="parallel" id="parallel">Is it possible to provide HTTP and HTTPS
        from the same server?</a></h3>
    <p>Yes. HTTP and HTTPS use different server ports (HTTP binds to
    port 80, HTTPS to port 443), so there is no direct conflict between
    them. You can either run two separate server instances bound to
    these ports, or use Apache's elegant virtual hosting facility to
    create two virtual servers, both served by the same instance of Apache
    - one responding over HTTP to requests on port 80, and the other
    responding over HTTPS to requests on port 443.</p>


<h3><a name="ports" id="ports">Which port does HTTPS use?</a></h3>
<p>You can run HTTPS on any port, but the standards specify port 443, which
    is where any HTTPS compliant browser will look by default. You can force
    your browser to look on a different port by specifying it in the URL. For
    example, if your server is set up to serve pages over HTTPS on port 8080,
    you can access them at <code>https://example.com:8080/</code></p>


<h3><a name="httpstest" id="httpstest">How do I speak HTTPS manually for testing purposes?</a></h3>
 <p>While you usually just use</p>

    <div class="example"><p><code>$ telnet localhost 80<br />
    GET / HTTP/1.0</code></p></div>

    <p>for simple testing of Apache via HTTP, it's not so easy for
    HTTPS because of the SSL protocol between TCP and HTTP. With the
    help of OpenSSL's <code>s_client</code> command, however, you can
    do a similar check via HTTPS:</p>

    <div class="example"><p><code>$ openssl s_client -connect localhost:443 -state -debug<br />
    GET / HTTP/1.0</code></p></div>

    <p>Before the actual HTTP response you will receive detailed
    information about the SSL handshake. For a more general command
    line client which directly understands both HTTP and HTTPS, can
    perform GET and POST operations, can use a proxy, supports byte
    ranges, etc. you should have a look at the nifty
    <a href="http://curl.haxx.se/">cURL</a> tool. Using this, you can
    check that Apache is responding correctly to requests via HTTP and
    HTTPS as follows:</p>

    <div class="example"><p><code>$ curl http://localhost/<br />
    $ curl https://localhost/</code></p></div>


<h3><a name="hang" id="hang">Why does the connection hang when I connect
    to my SSL-aware Apache server?</a></h3>

<p>This can happen when you try to connect to a HTTPS server (or virtual
    server) via HTTP (eg, using <code>http://example.com/</code> instead of
    <code>https://example.com</code>). It can also happen when trying to
    connect via HTTPS to a HTTP server (eg, using
    <code>https://example.com/</code> on a server which doesn't support HTTPS,
    or which supports it on a non-standard port). Make sure that you're
    connecting to a (virtual) server that supports SSL.</p>

<h3><a name="refused" id="refused">Why do I get ``Connection Refused'' messages,
    when trying to access my newly installed Apache+mod_ssl server via HTTPS?</a></h3>
<p>
    This error can be caused by an incorrect configuration.
    Please make sure that your <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> directives match your
    <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
    directives. If all else fails, please start afresh, using the default
    configuration provided by <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>.</p>


<h3><a name="envvars" id="envvars">Why are the <code>SSL_XXX</code> variables
    not available to my CGI &amp; SSI scripts?</a></h3>
<p>Please make sure you have ``<code>SSLOptions +StdEnvVars</code>''
    enabled for the context of your CGI/SSI requests.</p>


<h3><a name="relative" id="relative">How can I switch between HTTP and HTTPS in relative
    hyperlinks?</a></h3>

<p>Usually, to switch between HTTP and HTTPS, you have to use
    fully-qualified hyperlinks (because you have to change the URL
    scheme).  Using <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> however, you can
    manipulate relative hyperlinks, to achieve the same effect.</p>
    <pre class="prettyprint lang-config">RewriteEngine on
RewriteRule   "^/(.*)_SSL$"   "https://%{SERVER_NAME}/$1" [R,L]
RewriteRule   "^/(.*)_NOSSL$" "http://%{SERVER_NAME}/$1"  [R,L]</pre>


    <p>This rewrite ruleset lets you use hyperlinks of the form
    <code>&lt;a href="document.html_SSL"&gt;</code>, to switch to HTTPS
    in a relative link. (Replace SSL with NOSSL to switch to HTTP.)</p>

<h3><a name="keyscerts" id="keyscerts">What are RSA Private Keys, CSRs and Certificates?</a></h3>
<p>An RSA private key file is a digital file that you can use to decrypt
    messages sent to you. It has a public component which you distribute (via
    your Certificate file) which allows people to encrypt those messages to
    you.</p>
    <p>A Certificate Signing Request (CSR) is a digital file which contains
    your public key and your name. You send the CSR to a Certifying Authority
    (CA), who will convert it into a real Certificate, by signing it.</p>
    <p>A Certificate contains your
    RSA public key, your name, the name of the CA, and is digitally signed by
    the CA. Browsers that know the CA can verify the signature on that
    Certificate, thereby obtaining your RSA public key. That enables them to
    send messages which only you can decrypt.</p>
    <p>See the <a href="ssl_intro.html">Introduction</a> chapter for a general
    description of the SSL protocol.</p>


<h3><a name="startup" id="startup">Is there a difference on startup between
    a non-SSL-aware Apache and an SSL-aware Apache?</a></h3>
<p>Yes. In general, starting Apache with
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> built-in is just like starting Apache
    without it. However, if you have a passphrase on your SSL private
    key file, a startup dialog will pop up which asks you to enter the
    pass phrase.</p>

    <p>Having to manually enter the passphrase when starting the server
    can be problematic - for example, when starting the server from the
    system boot scripts. In this case, you can follow the steps
    <a href="#removepassphrase">below</a> to remove the passphrase from
    your private key. Bear in mind that doing so brings additional security
    risks - proceed with caution!</p>


<h3><a name="selfcert" id="selfcert">How do I create a self-signed SSL
Certificate for testing purposes?</a></h3>
    <ol>
    <li>Make sure OpenSSL is installed and in your <code>PATH</code>.<br />
    <br />
    </li>
    <li>Run the following command, to create <code>server.key</code> and
        <code>server.crt</code> files:<br />
        <code><strong>$ openssl req -new -x509 -nodes -out server.crt
                        -keyout server.key</strong></code><br />
        These can be used as follows in your <code>httpd.conf</code>
        file:
        <pre class="prettyprint lang-config">SSLCertificateFile    "/path/to/this/server.crt"
SSLCertificateKeyFile "/path/to/this/server.key"</pre>

    </li>
    <li>It is important that you are aware that this
        <code>server.key</code> does <em>not</em> have any passphrase.
        To add a passphrase to the key, you should run the following
        command, and enter &amp; verify the passphrase as requested.<br />
        <p><code><strong>$ openssl rsa -des3 -in server.key -out
        server.key.new</strong></code><br />
        <code><strong>$ mv server.key.new server.key</strong></code><br /></p>
        Please backup the <code>server.key</code> file, and the passphrase
        you entered, in a secure location.
    </li>
    </ol>


<h3><a name="realcert" id="realcert">How do I create a real SSL Certificate?</a></h3>
<p>Here is a step-by-step description:</p>
    <ol>
    <li>Make sure OpenSSL is installed and in your <code>PATH</code>.
    <br />
    <br />
    </li>
    <li>Create a RSA private key for your Apache server
       (will be Triple-DES encrypted and PEM formatted):<br />
       <br />
       <code><strong>$ openssl genrsa -des3 -out server.key 2048</strong></code><br />
       <br />
       Please backup this <code>server.key</code> file and the
       pass-phrase you entered in a secure location.
       You can see the details of this RSA private key by using the command:<br />

       <br />
       <code><strong>$ openssl rsa -noout -text -in server.key</strong></code><br />
       <br />
       If necessary, you can also create a decrypted PEM version (not
       recommended) of this RSA private key with:<br />
       <br />
       <code><strong>$ openssl rsa -in server.key -out server.key.unsecure</strong></code><br />
       <br />

    </li>
    <li>Create a Certificate Signing Request (CSR) with the server RSA private
       key (output will be PEM formatted):<br />
       <br />
       <code><strong>$ openssl req -new -key server.key -out server.csr</strong></code><br />
       <br />
       Make sure you enter the FQDN ("Fully Qualified Domain Name") of the
       server when OpenSSL prompts you for the "CommonName", i.e. when you
       generate a CSR for a website which will be later accessed via
       <code>https://www.foo.dom/</code>, enter "www.foo.dom" here.
       You can see the details of this CSR by using<br />

       <br />
       <code><strong>$ openssl req -noout -text -in server.csr</strong></code><br />
       <br />
    </li>
    <li>You now have to send this Certificate Signing Request (CSR) to
       a Certifying Authority (CA) to be signed. Once the CSR has been
       signed, you will have a real Certificate, which can be used by
       Apache. You can have a CSR signed by a commercial CA, or you can
       create your own CA to sign it.<br />
       Commercial CAs usually ask you to post the CSR into a web form,
       pay for the signing, and then send a signed Certificate, which
       you can store in a server.crt file.<br />

       For details on how to create your own CA, and use this to sign
       a CSR, see <a href="#ownca">below</a>.<br />

       Once your CSR has been signed, you can see the details of the
       Certificate as follows:<br />
       <br />
       <code><strong>$ openssl x509 -noout -text -in server.crt</strong></code><br />

    </li>
    <li>You should now have two files: <code>server.key</code> and
    <code>server.crt</code>. These can be used as follows in your
    <code>httpd.conf</code> file:
       <pre class="prettyprint lang-config">SSLCertificateFile    "/path/to/this/server.crt"
SSLCertificateKeyFile "/path/to/this/server.key"</pre>

       The <code>server.csr</code> file is no longer needed.
    </li>

    </ol>


<h3><a name="ownca" id="ownca">How do I create and use my own Certificate Authority (CA)?</a></h3>
    <p>The short answer is to use the <code>CA.sh</code> or <code>CA.pl</code>
    script provided by OpenSSL. Unless you have a good reason not to,
    you should use these for preference. If you cannot, you can create a
    self-signed certificate as follows:</p>

    <ol>
    <li>Create a RSA private key for your server
       (will be Triple-DES encrypted and PEM formatted):<br />
       <br />
       <code><strong>$ openssl genrsa -des3 -out server.key 2048</strong></code><br />
       <br />
       Please backup this <code>server.key</code> file and the
       pass-phrase you entered in a secure location.
       You can see the details of this RSA private key by using the
       command:<br />
       <br />
       <code><strong>$ openssl rsa -noout -text -in server.key</strong></code><br />
       <br />
       If necessary, you can also create a decrypted PEM version (not
       recommended) of this RSA private key with:<br />
       <br />
       <code><strong>$ openssl rsa -in server.key -out server.key.unsecure</strong></code><br />
       <br />
    </li>
    <li>Create a self-signed certificate (X509 structure)
       with the RSA key you just created (output will be PEM formatted):<br />
       <br />
       <code><strong>$ openssl req -new -x509 -nodes -sha1 -days 365
                       -key server.key -out server.crt -extensions usr_cert</strong></code><br />
       <br />
       This signs the server CSR and results in a <code>server.crt</code> file.<br />
       You can see the details of this Certificate using:<br />
       <br />
       <code><strong>$ openssl x509 -noout -text -in server.crt</strong></code><br />
       <br />
    </li>
    </ol>


<h3><a name="passphrase" id="passphrase">How can I change the pass-phrase on my private key file?</a></h3>
<p>You simply have to read it with the old pass-phrase and write it again,
    specifying the new pass-phrase. You can accomplish this with the following
    commands:</p>


    <p><code><strong>$ openssl rsa -des3 -in server.key -out server.key.new</strong></code><br />
    <code><strong>$ mv server.key.new server.key</strong></code><br /></p>

    <p>The first time you're asked for a PEM pass-phrase, you should
    enter the old pass-phrase. After that, you'll be asked again to
    enter a pass-phrase - this time, use the new pass-phrase. If you
    are asked to verify the pass-phrase, you'll need to enter the new
    pass-phrase a second time.</p>


<h3><a name="removepassphrase" id="removepassphrase">How can I get rid of the pass-phrase dialog at Apache startup time?</a></h3>
<p>The reason this dialog pops up at startup and every re-start
    is that the RSA private key inside your server.key file is stored in
    encrypted format for security reasons. The pass-phrase is needed to decrypt
    this file, so it can be read and parsed. Removing the pass-phrase
    removes a layer of security from your server - proceed with caution!</p>
    <ol>
    <li>Remove the encryption from the RSA private key (while
       keeping a backup copy of the original file):<br />
       <br />
       <code><strong>$ cp server.key server.key.org</strong></code><br />
       <code><strong>$ openssl rsa -in server.key.org -out server.key</strong></code><br />

       <br />
    </li>
    <li>Make sure the server.key file is only readable by root:<br />
       <br />
       <code><strong>$ chmod 400 server.key</strong></code><br />
       <br />
    </li>
    </ol>

    <p>Now <code>server.key</code> contains an unencrypted copy of the key.
    If you point your server at this file, it will not prompt you for a
    pass-phrase. HOWEVER, if anyone gets this key they will be able to
    impersonate you on the net. PLEASE make sure that the permissions on this
    file are such that only root or the web server user can read it
    (preferably get your web server to start as root but run as another
    user, and have the key readable only by root).</p>

    <p>As an alternative approach you can use the ``<code>SSLPassPhraseDialog
    exec:/path/to/program</code>'' facility. Bear in mind that this is
    neither more nor less secure, of course.</p>


<h3><a name="verify" id="verify">How do I verify that a private key matches its Certificate?</a></h3>
<p>A private key contains a series of numbers. Two of these numbers form
    the "public key", the others are part of the "private key". The "public
    key" bits are included when you generate a CSR, and subsequently form
    part of the associated Certificate.</p>
    <p>To check that the public key in your Certificate matches the public
    portion of your private key, you simply need to compare these numbers.
    To view the Certificate and the key run the commands:</p>

    <p><code><strong>$ openssl x509 -noout -text -in server.crt</strong></code><br />
    <code><strong>$ openssl rsa -noout -text -in server.key</strong></code></p>

    <p>The `modulus' and the `public exponent' portions in the key and the
    Certificate must match. As the public exponent is usually 65537
    and it's difficult to visually check that the long modulus numbers
    are the same, you can use the following approach:</p>

    <p><code><strong>$ openssl x509 -noout -modulus -in server.crt | openssl md5</strong></code><br />
    <code><strong>$ openssl rsa -noout -modulus -in server.key | openssl md5</strong></code></p>

    <p>This leaves you with two rather shorter numbers to compare. It is,
    in theory, possible that these numbers may be the same, without the
    modulus numbers being the same, but the chances of this are
    overwhelmingly remote.</p>
    <p>Should you wish to check to which key or certificate a particular
    CSR belongs you can perform the same calculation on the CSR as
    follows:</p>

    <p><code><strong>$ openssl req -noout -modulus -in server.csr | openssl md5</strong></code></p>


<h3><a name="pemder" id="pemder">How can I convert a certificate from PEM to DER format?</a></h3>
<p>The default certificate format for OpenSSL is PEM, which is simply
    Base64 encoded DER, with header and footer lines. For some applications
    (e.g. Microsoft Internet Explorer) you need the certificate in plain DER
    format. You can convert a PEM file <code>cert.pem</code> into the
    corresponding DER file <code>cert.der</code> using the following command:
    <code><strong>$ openssl x509 -in cert.pem -out cert.der -outform DER</strong></code></p>


<h3><a name="gid" id="gid">Why do browsers complain that they cannot verify my server certificate?</a></h3>

    <p>One reason this might happen is because your server certificate is signed
    by an intermediate CA. Various CAs, such as Verisign or Thawte, have started
    signing certificates not with their root certificate but with intermediate
    certificates.</p>

    <p>Intermediate CA certificates lie between the root CA certificate (which is
    installed in the browsers) and the server certificate (which you installed
    on the server). In order for the browser to be able to traverse and verify
    the trust chain from the server certificate to the root certificate it
    needs need to be given the intermediate certificates. The CAs should
    be able to provide you such intermediate certificate packages that can be
    installed on the server.</p>

    <p>You need to include those intermediate certificates with the
    <code class="directive"><a href="../mod/mod_ssl.html#sslcertificatechainfile">SSLCertificateChainFile</a></code>
    directive.</p>

</ul>

<h3><a name="random" id="random">Why do I get lots of random SSL protocol
errors under heavy server load?</a></h3>
<p>There can be a number of reasons for this, but the main one
    is problems with the SSL session Cache specified by the
    <code class="directive"><a href="../mod/mod_ssl.html#sslsessioncache">SSLSessionCache</a></code> directive. The DBM session
    cache is the most likely source of the problem, so using the SHM session cache (or
    no cache at all) may help.</p>


<h3><a name="load" id="load">Why does my webserver have a higher load, now
that it serves SSL encrypted traffic?</a></h3>
<p>SSL uses strong cryptographic encryption, which necessitates a lot of
    number crunching. When you request a webpage via HTTPS, everything (even
    the images) is encrypted before it is transferred. So increased HTTPS
    traffic leads to load increases.</p>


<h3><a name="establishing" id="establishing">Why do HTTPS connections to my server
sometimes take up to 30 seconds to establish a connection?</a></h3>
<p>This is usually caused by a <code>/dev/random</code> device for
    <code class="directive"><a href="../mod/mod_ssl.html#sslrandomseed">SSLRandomSeed</a></code> which blocks the
    read(2) call until enough entropy is available to service the
    request. More information is available in the reference
    manual for the <code class="directive"><a href="../mod/mod_ssl.html#sslrandomseed">SSLRandomSeed</a></code>
    directive.</p>


<h3><a name="ciphers" id="ciphers">What SSL Ciphers are supported by mod_ssl?</a></h3>
<p>Usually, any SSL ciphers supported by the version of OpenSSL in use,
    are also supported by <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>. Which ciphers are
    available can depend on the way you built OpenSSL. Typically, at
    least the following ciphers are supported:</p>

    <ol>
    <li>RC4 with SHA1</li>
    <li>AES with SHA1</li>
    <li>Triple-DES with SHA1</li>
    </ol>

    <p>To determine the actual list of ciphers available, you should run
    the following:</p>
    <div class="example"><p><code>$ openssl ciphers -v</code></p></div>


<h3><a name="adh" id="adh">Why do I get ``no shared cipher'' errors, when
trying to use Anonymous Diffie-Hellman (ADH) ciphers?</a></h3>
<p>By default, OpenSSL does <em>not</em> allow ADH ciphers, for security
    reasons. Please be sure you are aware of the potential side-effects
    if you choose to enable these ciphers.</p>
    <p>In order to use Anonymous Diffie-Hellman (ADH) ciphers, you must
    build OpenSSL with ``<code>-DSSL_ALLOW_ADH</code>'', and then add
    ``<code>ADH</code>'' into your <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code>.</p>


<h3><a name="sharedciphers" id="sharedciphers">Why do I get a 'no shared ciphers'
error when connecting to my newly installed server?</a></h3>
<p>Either you have made a mistake with your
    <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code>
    directive (compare it with the pre-configured example in
    <code>extra/httpd-ssl.conf</code>) or you chose to use DSA/DH
    algorithms instead of RSA when you generated your private key
    and ignored or overlooked the warnings. If you have chosen
    DSA/DH, then your server cannot communicate using RSA-based SSL
    ciphers (at least until you configure an additional RSA-based
    certificate/key pair). Modern browsers like NS or IE can only
    communicate over SSL using RSA ciphers. The result is the
    "no shared ciphers" error. To fix this, regenerate your server
    certificate/key pair, using the RSA algorithm.</p>


<h3><a name="vhosts" id="vhosts">Why can't I use SSL with name-based/non-IP-based virtual hosts?</a></h3>
<p>The reason is very technical, and a somewhat "chicken and egg" problem.
    The SSL protocol layer stays below the HTTP protocol layer and
    encapsulates HTTP. When an SSL connection (HTTPS) is established
    Apache/mod_ssl has to negotiate the SSL protocol parameters with the
    client. For this, mod_ssl has to consult the configuration of the virtual
    server (for instance it has to look for the cipher suite, the server
    certificate, etc.). But in order to go to the correct virtual server
    Apache has to know the <code>Host</code> HTTP header field. To do this, the
    HTTP request header has to be read. This cannot be done before the SSL
    handshake is finished, but the information is needed in order to
    complete the SSL handshake phase. See the next question for how to
    circumvent this issue.</p>
    
    <p>Note that if you have a wildcard SSL certificate, or a
    certificate that has multiple hostnames on it using subjectAltName
    fields, you can use SSL on name-based virtual hosts without further
    workarounds.</p>


<h3><a name="vhosts2" id="vhosts2">Is it possible to use Name-Based
Virtual Hosting to identify different SSL virtual hosts?</a></h3>
    <p>Name-Based Virtual Hosting is a very popular method of identifying
    different virtual hosts. It allows you to use the same IP address and
    the same port number for many different sites. When people move on to
    SSL, it seems natural to assume that the same method can be used to have
    lots of different SSL virtual hosts on the same server.</p>

    <p>It is possible, but only if using a 2.2.12 or later web server,
    built with 0.9.8j or later OpenSSL.  This is because it requires a
    feature that only the most recent revisions of the SSL
    specification added, called Server Name Indication (SNI).</p>

    <p>Note that if you have a wildcard SSL certificate, or a
    certificate that has multiple hostnames on it using subjectAltName
    fields, you can use SSL on name-based virtual hosts without further
    workarounds.</p>

    <p>The reason is that the SSL protocol is a separate layer which
    encapsulates the HTTP protocol. So the SSL session is a separate
    transaction, that takes place before the HTTP session has begun.
    The server receives an SSL request on IP address X and port Y
    (usually 443). Since the SSL request did not contain any Host:
    field, the server had no way to decide which SSL virtual host to use.
    Usually, it just used the first one it found which matched the
    port and IP address specified.</p>

    <p>If you are using a version of the web server and OpenSSL that
    support SNI, though, and the client's browser also supports SNI,
    then the hostname is included in the original SSL request, and the
    web server can select the correct SSL virtual host.</p>

    <p>You can, of course, use Name-Based Virtual Hosting to identify many
    non-SSL virtual hosts (all on port 80, for example) and then
    have a single SSL virtual host (on port 443). But if you do this,
    you must make sure to put the non-SSL port number on the NameVirtualHost
    directive, e.g.</p>

    <pre class="prettyprint lang-config">NameVirtualHost 192.168.1.1:80</pre>


    <p>Other workaround solutions include: </p>

    <p>Using separate IP addresses for different SSL hosts.
    Using different port numbers for different SSL hosts.</p>


<h3><a name="comp" id="comp">How do I get SSL compression working?</a></h3>
<p>Although SSL compression negotiation was defined in the specification
of SSLv2 and TLS, it took until May 2004 for RFC 3749 to define DEFLATE as
a negotiable standard compression method.
</p>
<p>OpenSSL 0.9.8 started to support this by default when compiled with the
<code>zlib</code> option. If both the client and the server support compression,
it will be used. However, most clients still try to initially connect with an
SSLv2 Hello. As SSLv2 did not include an array of preferred compression algorithms
in its handshake, compression cannot be negotiated with these clients.
If the client disables support for SSLv2, either an SSLv3 or TLS Hello
may be sent, depending on which SSL library is used, and compression may
be set up. You can verify whether clients make use of SSL compression by
logging the <code>%{SSL_COMPRESS_METHOD}x</code> variable.
</p>


<h3><a name="lockicon" id="lockicon">When I use Basic Authentication over HTTPS
the lock icon in Netscape browsers stays unlocked when the dialog pops up.
Does this mean the username/password is being sent unencrypted?</a></h3>
<p>No, the username/password is transmitted encrypted. The icon in
    Netscape browsers is not actually synchronized with the SSL/TLS layer.
    It only toggles to the locked state when the first part of the actual
    webpage data is transferred, which may confuse people. The Basic
    Authentication facility is part of the HTTP layer, which is above
    the SSL/TLS layer in HTTPS. Before any HTTP data communication takes
    place in HTTPS, the SSL/TLS layer has already completed its handshake
    phase, and switched to encrypted communication. So don't be
    confused by this icon.</p>


<h3><a name="msie" id="msie">Why do I get I/O errors when connecting via
HTTPS to an Apache+mod_ssl server with older versions of Microsoft Internet
Explorer (MSIE)?</a></h3>
<p>The first reason is that the SSL implementation in some MSIE versions has
    some subtle bugs related to the HTTP keep-alive facility and the SSL close
    notify alerts on socket connection close. Additionally the interaction
    between SSL and HTTP/1.1 features are problematic in some MSIE versions.
    You can work around these problems by forcing Apache not to use HTTP/1.1,
    keep-alive connections or send the SSL close notify messages to MSIE clients.
    This can be done by using the following directive in your SSL-aware
    virtual host section:</p>
    <pre class="prettyprint lang-config">SetEnvIf User-Agent "MSIE [2-5]" \
         nokeepalive ssl-unclean-shutdown \
         downgrade-1.0 force-response-1.0</pre>

    <p>Further, some MSIE versions have problems with particular ciphers.
    Unfortunately, it is not possible to implement a MSIE-specific
    workaround for this, because the ciphers are needed as early as the
    SSL handshake phase. So a MSIE-specific
    <code class="directive"><a href="../mod/mod_setenvif.html#setenvif">SetEnvIf</a></code> won't solve these
    problems. Instead, you will have to make more drastic
    adjustments to the global parameters. Before you decide to do
    this, make sure your clients really have problems. If not, do not
    make these changes - they will affect <em>all</em> your clients, MSIE
    or otherwise.</p>


<h3><a name="srp" id="srp">How do I enable TLS-SRP?</a></h3>
    <p>TLS-SRP (Secure Remote Password key exchange for TLS, specified in RFC 5054)
    can supplement or replace certificates in authenticating an SSL connection.
    To use TLS-SRP, set the
    <code class="directive"><a href="../mod/mod_ssl.html#sslsrpverifierfile">SSLSRPVerifierFile</a></code> directive to
    point to an OpenSSL SRP verifier file. To create the verifier file, use the
    <code>openssl</code> tool:</p>
    <div class="example"><p><code>
    openssl srp -srpvfile passwd.srpv -add username
    </code></p></div>
    <p>After creating this file, specify it in the SSL server configuration:</p>
    <div class="example"><p><code>
    SSLSRPVerifierFile /path/to/passwd.srpv
    </code></p></div>
    <p>To force clients to use non-certificate TLS-SRP cipher suites, use the
    following directive:</p>
    <div class="example"><p><code>
    SSLCipherSuite "!DSS:!aRSA:SRP"
    </code></p></div>


<h3><a name="javadh" id="javadh">Why do I get handshake failures with Java-based clients when using a certificate with more than 1024 bits?</a></h3>
    <p>Beginning with version 2.4.7,
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> will use DH parameters which include primes
    with lengths of more than 1024 bits. Java 7 and earlier limit their
    support for DH prime sizes to a maximum of 1024 bits, however.</p>

    <p>If your Java-based client aborts with exceptions such as
    <code>java.lang.RuntimeException: Could not generate DH keypair</code> and
    <code>java.security.InvalidAlgorithmParameterException: Prime size must be
    multiple of 64, and can only range from 512 to 1024 (inclusive)</code>,
    and httpd logs <code>tlsv1 alert internal error (SSL alert number 80)</code>
    (at <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code> <code>info</code>
    or higher), you can either rearrange mod_ssl's cipher list with
    <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code>
    (possibly in conjunction with <code class="directive"><a href="../mod/mod_ssl.html#sslhonorcipherorder">SSLHonorCipherOrder</a></code>),
    or you can use custom DH parameters with a 1024-bit prime, which
    will always have precedence over any of the built-in DH parameters.</p>

    <p>To generate custom DH parameters, use the <code>openssl dhparam 1024</code>
    command. Alternatively, you can use the following standard 1024-bit DH
    parameters from <a href="http://www.ietf.org/rfc/rfc2409.txt">RFC 2409</a>,
    section 6.2:</p>
    <div class="example"><pre>-----BEGIN DH PARAMETERS-----
MIGHAoGBAP//////////yQ/aoiFowjTExmKLgNwc0SkCTgiKZ8x0Agu+pjsTmyJR
Sgh5jjQE3e+VGbPNOkMbMCsKbfJfFDdP4TVtbVHCReSFtXZiXn7G9ExC6aY37WsL
/1y29Aa37e44a/taiZ+lrp8kEXxLH+ZJKGZR7OZTgf//////////AgEC
-----END DH PARAMETERS-----</pre></div>
    <p>Add the custom parameters including the "BEGIN DH PARAMETERS" and
    "END DH PARAMETERS" lines to the end of the first certificate file
    you have configured using the
    <code class="directive"><a href="../mod/mod_ssl.html#sslcertificatefile">SSLCertificateFile</a></code> directive.</p>

    </dd>
    </dl>


<h3><a name="contact" id="contact">What support contacts are available in case
of mod_ssl problems?</a></h3>
 <p>The following lists all support possibilities for mod_ssl, in order of
         preference. Please go through these possibilities
         <em>in this order</em> - don't just pick the one you like the look of. </p>
    <ol>

    <li><em>Send a Problem Report to the Apache httpd Users Support Mailing List</em><br />
        <a href="mailto:users@httpd.apache.org">
        users@httpd.apache.org</a><br />
        This is the second way of submitting your problem report. Again, you must
        subscribe to the list first, but you can then easily discuss your problem
        with the whole Apache httpd user community.
    </li>

    <li><em>Write a Problem Report in the Bug Database</em><br />
        <a href="http://httpd.apache.org/bug_report.html">
        http://httpd.apache.org/bug_report.html</a><br />
        This is the last way of submitting your problem report. You should only
        do this if you've already posted to the mailing lists, and had no success.
        Please follow the instructions on the above page <em>carefully</em>.
    </li>
    </ol>


<h3><a name="reportdetails" id="reportdetails">What information should I
provide when writing a bug report?</a></h3>
<p>You should always provide at least the following information:</p>

    <dl>
    <dt>Apache httpd and OpenSSL version information</dt>
    <dd>The Apache version can be determined
        by running <code>httpd -v</code>. The OpenSSL version can be
        determined by running <code>openssl version</code>. Alternatively, if
        you have Lynx installed, you can run the command <code>lynx -mime_header
        http://localhost/ | grep Server</code> to gather this information in a
        single step.
    </dd>

    <dt>The details on how you built and installed Apache httpd and OpenSSL</dt>
    <dd>For this you can provide a logfile of your terminal session which shows
    the configuration and install steps. If this is not possible, you
    should at least provide the <code class="program"><a href="../programs/configure.html">configure</a></code> command line you used.
    </dd>

    <dt>In case of core dumps please include a Backtrace</dt>
    <dd>If your Apache httpd dumps its core, please attach
    a stack-frame ``backtrace'' (see <a href="#backtrace">below</a>
    for information on how to get this). This information is required
    in order to find a reason for your core dump.
    </dd>

    <dt>A detailed description of your problem</dt>
    <dd>Don't laugh, we really mean it! Many problem reports don't
    include a description of what the actual problem is. Without this,
    it's very difficult for anyone to help you. So, it's in your own
    interest (you want the problem be solved, don't you?) to include as
    much detail as possible, please. Of course, you should still include
    all the essentials above too.
    </dd>
    </dl>


<h3><a name="coredumphelp" id="coredumphelp">I had a core dump, can you help me?</a></h3>
<p>In general no, at least not unless you provide more details about the code
    location where Apache dumped core. What is usually always required in
    order to help you is a backtrace (see next question). Without this
    information it is mostly impossible to find the problem and help you in
    fixing it.</p>


<h3><a name="backtrace" id="backtrace">How do I get a backtrace, to help find
the reason for my core dump?</a></h3>
<p>Following are the steps you will need to complete, to get a backtrace:</p>
    <ol>
    <li>Make sure you have debugging symbols available, at least
        in Apache. On platforms where you use GCC/GDB, you will have to build
        Apache+mod_ssl with ``<code>OPTIM="-g -ggdb3"</code>'' to get this. On
        other platforms at least ``<code>OPTIM="-g"</code>'' is needed.
    </li>

    <li>Start the server and try to reproduce the core-dump. For this you may
        want to use a directive like ``<code>CoreDumpDirectory /tmp</code>'' to
        make sure that the core-dump file can be written. This should result
        in a <code>/tmp/core</code> or <code>/tmp/httpd.core</code> file. If you
        don't get one of these, try running your server under a non-root UID.
        Many modern kernels do not allow a process to dump core after it has
        done a <code>setuid()</code> (unless it does an <code>exec()</code>) for
        security reasons (there can be privileged information left over in
        memory). If necessary, you can run <code>/path/to/httpd -X</code>
        manually to force Apache to not fork.
    </li>

    <li>Analyze the core-dump. For this, run <code>gdb /path/to/httpd
        /tmp/httpd.core</code> or a similar command. In GDB, all you
        have to do then is to enter <code>bt</code>, and voila, you get the
        backtrace. For other debuggers consult your local debugger manual.
    </li>
    </ol>

<p>Ce document couvre la compatibilité ascendante entre mod_ssl et
d'autres solutions SSL. mod_ssl n'est pas la seule solution SSL pour Apache ;
quatre autres produits sont (ou ont été) également disponibles :
<a href="http://www.apache-ssl.org/">Apache-SSL</a>, le produit libre de
Ben Laurie (d'où mod_ssl est issu à l'origine en 1998), Secure
Web Server, un produit commercial de Red Hat (basé sur mod_ssl),
Raven SSL Module, un produit commercial
de Covalent (basé lui aussi sur mod_ssl), et enfin <a href="http://www.redhat.com/explore/stronghold/">Stronghold</a>, produit
commercial de C2Net et maintenant de Red Hat, (basé sur une branche
d'évolution différente appelée Sioux jusqu'à Stronghold 2.x et basé sur
mod_ssl depuis Stronghold 3.x).</p>

<p>En plus de ses fonctionnalités propres, mod_ssl rassemble la plupart de
celles des autres solutions SSL, si bien qu'il est très simple de
migrer depuis un module plus ancien vers mod_ssl. Les directives de
configuration et les noms des variables d'environnement utilisés par les
solutions SSL plus anciennes diffèrent de ceux qu'utilise mod_ssl ;
les tableaux de correspondance ci-dessous fournissent les équivalences
de termes utilisés par mod_ssl.</p>

<h3><a name="mutex" id="mutex">Pourquoi le démarrage d'Apache provoque-t-il des
erreurs de permission en rapport avec SSLMutex ?</a></h3>
    <p>Des erreurs telles que ``<code>mod_ssl: Child could not open
    SSLMutex lockfile /opt/apache/logs/ssl_mutex.18332 (avec l'erreur
    système qui suit) [...] System: Permission denied (errno: 13)</code>''
    sont souvent provoquées par des permissions trop restrictives sur les
    répertoires <em>parents</em>. Assurez-vous que tous les répertoires
    parents (ici <code>/opt</code>, <code>/opt/apache</code> et
    <code>/opt/apache/logs</code>) ont le bit x positionné au moins pour
    l'UID sous lequel les processus enfants d'Apache s'exécutent (voir la
    directive <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code>).</p>


<h3><a name="entropy" id="entropy">Pourquoi mod_ssl s'arrête-t-il avec l'erreur
"Failed to generate temporary 512 bit RSA private key" au démarrage
d'Apache ?</a></h3>
    <p>Pour fonctionner correctement, les logiciels de cryptographie ont
    besoin d'une source de données aléatoires. De nombreux systèmes
    d'exploitation libres proposent un "périphérique source d'entropie"
    qui fournit ce service (il se nomme en général
    <code>/dev/random</code>). Sur d'autres systèmes, les applications
    doivent amorcer manuellement
    le Générateur de Nombres Pseudo-Aléatoires d'OpenSSL
    (Pseudo Random Number Generator -PRNG) à l'aide de données appropriées
    avant de générer des clés ou d'effectuer un chiffrement à clé
    publique. Depuis la version 0.9.5, les fonctions d'OpenSSL qui nécessitent
    des données aléatoires provoquent une erreur si le PRNG n'a pas été amorcé
    avec une source de données aléatoires d'au moins 128 bits.</p>
    <p>Pour éviter cette erreur, <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> doit fournir
    suffisamment d'entropie au PRNG pour lui permettre de fonctionner
    correctement. Ce niveau d'entropie est défini par la directive
    <code class="directive"><a href="../mod/mod_ssl.html#sslrandomseed">SSLRandomSeed</a></code>.</p>

<h3><a name="parallel" id="parallel">Peut-on faire cohabiter HTTP et HTTPS sur le même
serveur ?</a></h3>
    <p>Oui. HTTP et HTTPS utilisent des ports différents (HTTP écoute le port
    80 et HTTPS le port 443), si bien qu'il n'y a pas de conflit direct entre
    les deux. Vous pouvez soit exécuter deux instances séparées du serveur,
    chacune d'entre elles écoutant l'un de ces ports, soit utiliser l'élégante
    fonctionnalité d'Apache que constituent les hôtes virtuels pour créer
    deux serveurs virtuels gérés par la même instance d'Apache - le
    premier serveur répondant en HTTP aux requêtes sur le port 80,
    le second répondant en HTTPS aux requêtes sur le port
    443.</p>


<h3><a name="ports" id="ports">Quel port HTTPS utilise-t-il ?</a></h3>
<p>Vous pouvez associer le protocole HTTPS à n'importe quel port, mais le port
standard est le port 443, que tout navigateur compatible HTTPS va utiliser par
défaut. Vous pouvez forcer votre navigateur à utiliser un port différent en le
précisant dans l'URL. Par exemple, si votre serveur est configuré pour
servir des pages en HTTPS sur le port 8080, vous pourrez y accéder par
l'adresse <code>https://example.com:8080/</code>.</p>


<h3><a name="httpstest" id="httpstest">Comment s'exprimer en langage HTTPS à des fins
de test ?</a></h3>
 <p>Alors que vous utilisez simplement</p>

    <div class="example"><p><code>$ telnet localhost 80<br />
    GET / HTTP/1.0</code></p></div>

    <p>pour tester facilement Apache via HTTP, les choses ne sont pas si
    simples pour HTTPS à cause du protocole SSL situé entre TCP et HTTP.
    La commande OpenSSL <code>s_client</code> vous permet cependant
    d'effectuer un test similaire via HTTPS :</p>

    <div class="example"><p><code>$ openssl s_client -connect localhost:443 -state -debug<br />
    GET / HTTP/1.0</code></p></div>

    <p>Avant la véritable réponse HTTP, vous recevrez des informations
    détaillées à propos de l'établissement de la connexion SSL. Si vous
    recherchez un client en ligne de commande à usage plus général qui comprend
    directement HTTP et HTTPS, qui peut effectuer des opérations GET et POST,
    peut utiliser un mandataire, supporte les requêtes portant sur une partie
    d'un fichier (byte-range), etc..., vous devriez vous tourner vers
    l'excellent outil <a href="http://curl.haxx.se/">cURL</a>. Grâce à lui,
    vous pouvez vérifier si Apache répond correctement aux requêtes via
    HTTP et HTTPS comme suit :</p>

    <div class="example"><p><code>$ curl http://localhost/<br />
    $ curl https://localhost/</code></p></div>


<h3><a name="hang" id="hang">Pourquoi la communication se bloque-t-elle lorsque je
me connecte à mon serveur Apache configuré pour SSL ?</a></h3>
<p>Ceci peut arriver si vous vous connectez à un serveur HTTPS (ou à
un serveur virtuel) via HTTP (par exemple, en utilisant
<code>http://example.com/</code> au lieu de <code>https://example.com</code>).
Cela peut aussi arriver en essayant de vous connecter via HTTPS à un
serveur HTTP (par exemple, en utilisant <code>https://example.com/</code>
avec un serveur qui ne supporte pas HTTPS, ou le supporte, mais sur un
port non standard). Assurez-vous que vous vous connectez bien à un
serveur (virtuel) qui supporte SSL.</p>


<h3><a name="refused" id="refused">Pourquoi, lorsque je tente d'accéder en HTTPS à mon
serveur Apache+mod_ssl fraîchement installé, l'erreur ``Connection Refused''
s'affiche-t-elle ?</a></h3>
<p>Une configuration incorrecte peut provoquer ce type d'erreur.
Assurez-vous que vos directives <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> s'accordent avec vos directives
    <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>. Si
    l'erreur persiste, recommencez depuis le début en restaurant la
    configuration par défaut fournie par<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>.</p>


<h3><a name="envvars" id="envvars">Pourquoi les variables <code>SSL_XXX</code>
ne sont-elles pas disponibles dans mes scripts CGI et SSI ?</a></h3>
<p>Assurez-vous que la directive ``<code>SSLOptions +StdEnvVars</code>'' est

<h3><a name="relative" id="relative">Comment puis-je basculer entre les protocoles HTTP et
HTTPS dans les hyperliens relatifs ?</a></h3>

<p>Normalement, pour basculer entre HTTP et HTTPS, vous devez utiliser des
hyperliens pleinement qualifiés (car vous devez modifier le schéma de l'URL).
Cependant, à l'aide du module <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>, vous pouvez
manipuler des hyperliens relatifs, pour obtenir le même effet.</p>
    <pre class="prettyprint lang-config">RewriteEngine on
RewriteRule   "^/(.*)_SSL$"   "https://%{SERVER_NAME}/$1" [R,L]
RewriteRule   "^/(.*)_NOSSL$" "http://%{SERVER_NAME}/$1"  [R,L]</pre>


    <p>Ce jeu de règles rewrite vous permet d'utiliser des hyperliens de la
    forme <code>&lt;a href="document.html_SSL"&gt;</code> pour passer en HTTPS
    dans les liens relatifs. (Remplacez SSL par NOSSL pour passer en HTTP.)</p>

<h3><a name="keyscerts" id="keyscerts">Qu'est-ce qu'un clé privée RSA, un certificat,
une demande de signature de certificat (CSR) ?</a></h3>
<p>Un fichier de clé privée RSA est un fichier numérique que vous pouvez
utiliser pour déchiffrer des messages que l'on vous a envoyés. Il a son
pendant à caractère public que vous pouvez distribuer (par le biais de votre
certificat), ce qui permet aux utilisateurs de chiffrer les messages qu'ils
vous envoient.</p>
    <p>Une Demande de Signature de Certificat (CSR) est un fichier numérique
    qui contient votre clé publique et votre nom. La CSR doit être envoyée à
    une Autorité de Certification (CA), qui va la convertir en vrai certificat
    en la signant.</p>
    <p>Un certificat contient votre clé publique RSA, votre nom, le nom
    de la CA, et est signé numériquement par cette dernière. Les navigateurs
    qui reconnaissent la CA peuvent vérifier la signature du certificat, et
    ainsi en extraire votre clé publique RSA. Ceci leur permet de vous envoyer
    des messages chiffrés que vous seul pourrez déchiffrer.</p>
    <p>Se référer au chapitre <a href="ssl_intro.html">Introduction</a>
    pour une description générale du protocole SSL.</p>


<h3><a name="startup" id="startup">Y a-t-il une différence au démarrage entre un serveur
Apache non SSL et un serveur Apache supportant SSL ?</a></h3>
<p>Oui. En général, avec ou sans <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> intégré, le démarrage
d'Apache ne présente pas de différences. Cependant, si votre fichier de clé
privée SSL possède un mot de passe, vous devrez le taper au démarrage
d'Apache.</p>

    <p>Devoir entrer manuellement le mot de passe au démarrage du serveur peut
    poser quelques problèmes - par exemple, quand le serveur est démarré au
    moyen de scripts au lancement du système. Dans ce cas, vous pouvez suivre
    les étapes <a href="#removepassphrase">ci-dessous</a> pour supprimer le
    mot de passe de votre clé privée. Gardez à l'esprit qu'agir ainsi augmente
    les risques de sécurité - agissez avec précaution !</p>


<h3><a name="selfcert" id="selfcert">Comment créer un certificat auto-signé SSL à des
fins de test ?</a></h3>
    <ol>
    <li>Vérifiez qu'OpenSSL est installé et l'exécutable openssl dans votre
    <code>PATH</code>.<br />
    <br />
    </li>
    <li>Exécuter la commande suivante pour créer les fichiers
    <code>server.key</code> et <code>server.crt</code> :<br />
	<code><strong>$ openssl req -new -x509 -nodes -out server.crt
			-keyout server.key</strong></code><br />
	Ces fichiers seront utilisés comme suit dans votre
	<code>httpd.conf</code> :
        <pre class="prettyprint lang-config">SSLCertificateFile    "/path/to/this/server.crt"
SSLCertificateKeyFile "/path/to/this/server.key"</pre>

    </li>
    <li>Il est important de savoir que le fichier <code>server.key</code> n'a
    <em>pas</em> de mot de passe. Pour ajouter un mot de passe à la clé, vous
    devez exécuter la commande suivante et confirmer le mot de passe comme
    demandé.<br />
	<p><code><strong>$ openssl rsa -des3 -in server.key -out
	server.key.new</strong></code><br />
	<code><strong>$ mv server.key.new server.key</strong></code><br /></p>
	Sauvegardez le fichier <code>server.key</code> ainsi que son mot de
	passe en lieu sûr.
    </li>
    </ol>


<h3><a name="realcert" id="realcert">Comment créer un vrai certificat SSL ?</a></h3>
<p>Voici la marche à suivre pas à pas :</p>
    <ol>
    <li>Assurez-vous qu'OpenSSL est bien installé et dans votre <code>PATH</code>.
    <br />
    <br />
    </li>
    <li>Créez une clé privée RSA pour votre serveur Apache
    	(elle sera au format PEM et chiffrée en Triple-DES):<br />
       <br />
       <code><strong>$ openssl genrsa -des3 -out server.key 2048</strong></code><br />
       <br />
       Enregistrez le fichier <code>server.key</code> et le mot de passe
       éventuellement défini en lieu sûr.
       Vous pouvez afficher les détails de cette clé privée RSA à l'aide de la
       commande :<br />

       <br />
       <code><strong>$ openssl rsa -noout -text -in server.key</strong></code><br />
       <br />
       Si nécessaire, vous pouvez aussi créer une version PEM non chiffrée
       (non recommandé) de clé privée RSA avec :<br />
       <br />
       <code><strong>$ openssl rsa -in server.key -out server.key.unsecure</strong></code><br />
       <br />

    </li>
    <li>Créez une Demande de signature de Certificat (CSR) à l'aide de la
    clé privée précédemment générée (la sortie sera au format PEM):<br />
       <br />
       <code><strong>$ openssl req -new -key server.key -out server.csr</strong></code><br />
       <br />
       Vous devez entrer le Nom de Domaine Pleinement Qualifié
       ("Fully Qualified Domain Name" ou FQDN) de votre serveur lorsqu'OpenSSL
       vous demande le "CommonName", c'est à dire que si vous générez une CSR
       pour un site web auquel on accèdera par l'URL
       <code>https://www.foo.dom/</code>, le FQDN sera "www.foo.dom". Vous
       pouvez afficher les détails de ce CSR avec :<br />

       <br />
       <code><strong>$ openssl req -noout -text -in server.csr</strong></code><br />
       <br />
    </li>
    <li>Vous devez maintenant envoyer la CSR à une Autorité de Certification
    (CA), afin que cette dernière puisse la signer. Une fois la CSR signée,
    vous disposerez d'un véritable certificat que vous pourrez utiliser avec
    Apache. Vous pouvez faire signer votre CSR par une CA commerciale ou par
    votre propre CA.<br />
       Les CAs commerciales vous demandent en général de leur envoyer la CSR
       par l'intermédiaire d'un formulaire web, de régler le montant de la
       signature, puis vous envoient un certificat signé que vous pouvez
       enregistrer dans un fichier server.crt.

       Pour plus de détails sur la manière de créer sa propre CA, et de
       l'utiliser pour signer une CSR, voir <a href="#ownca">ci-dessous</a>.<br />

       Une fois la CSR signée, vous pouvez afficher les détails du certificat
       comme suit :<br />
       <br />
       <code><strong>$ openssl x509 -noout -text -in server.crt</strong></code><br />

    </li>
    <li>Vous devez maintenant disposer de deux fichiers :
    <code>server.key</code> et <code>server.crt</code>. Ils sont précisés dans
    votre fichier <code>httpd.conf</code> comme suit :
       <pre class="prettyprint lang-config">SSLCertificateFile    "/path/to/this/server.crt"
SSLCertificateKeyFile "/path/to/this/server.key"</pre>

       Le fichier <code>server.csr</code> n'est plus nécessaire.
    </li>

    </ol>


<h3><a name="ownca" id="ownca">Comment créer et utiliser sa propre Autorité de
certification (CA) ?</a></h3>
    <p>La solution la plus simple consiste à utiliser les scripts
    <code>CA.sh</code> ou <code>CA.pl</code> fournis avec OpenSSL. De
    préférence, utilisez cette solution, à moins que vous ayez de bonnes
    raisons de ne pas le faire. Dans ce dernier cas, vous pouvez créer un
    certificat auto-signé comme suit :</p>

    <ol>
    <li>Créez une clé privée RSA pour votre serveur
    	(elle sera au format PEM et chiffrée en Triple-DES) :<br />
       <br />
       <code><strong>$ openssl genrsa -des3 -out server.key 2048</strong></code><br />
       <br />
       Sauvegardez le fichier <code>server.key</code> et le mot de passe
       éventuellement défini en lieu sûr.
       Vous pouvez afficher les détails de cette clé privée RSA à l'aide de la
       commande :<br />
       <br />
       <code><strong>$ openssl rsa -noout -text -in server.key</strong></code><br />
       <br />
       Si nécessaire, vous pouvez aussi créer une version PEM non chiffrée
       (non recommandé) de cette clé privée RSA	 avec :<br />
       <br />
       <code><strong>$ openssl rsa -in server.key -out server.key.unsecure</strong></code><br />
       <br />
    </li>
    <li>Créez un certificat auto-signé (structure X509) à l'aide de la clé RSA
    que vous venez de générer (la sortie sera au format PEM) :<br />
       <br />
       <code><strong>$ openssl req -new -x509 -nodes -sha1 -days 365
		       -key server.key -out server.crt -extensions usr_cert</strong></code><br />
       <br />
       Cette commande signe le certificat du serveur et produit un fichier
       <code>server.crt</code>. Vous pouvez afficher les détails de ce
       certificat avec :<br />
       <br />
       <code><strong>$ openssl x509 -noout -text -in server.crt</strong></code><br />
       <br />
    </li>
    </ol>


<h3><a name="passphrase" id="passphrase">Comment modifier le mot de passe
de ma clé privée ?</a></h3>
<p>Vous devez simplement lire la clé avec l'ancien mot de passe et la
réécrire en spécifiant le nouveau mot de passe. Pour cela, vous pouvez
utiliser les commandes suivantes :</p>


    <p><code><strong>$ openssl rsa -des3 -in server.key -out server.key.new</strong></code><br />
    <code><strong>$ mv server.key.new server.key</strong></code><br /></p>

    <p>La première fois qu'il vous est demandé un mot de passe PEM, vous
    devez entrer l'ancien mot de passe. Ensuite, on vous demandera d'entrer
    encore un mot de passe - cette fois, entrez le nouveau mot de passe. Si on
    vous demande de vérifier le mot de passe, vous devrez entrer le nouveau
    mot de passe une seconde fois.</p>


<h3><a name="removepassphrase" id="removepassphrase">Comment démarrer Apache sans avoir à entrer de
mot de passe ?</a></h3>
<p>L'apparition de ce dialogue au démarrage et à chaque redémarrage provient
du fait que la clé privée RSA contenue dans votre fichier server.key est
enregistrée sous forme chiffrée pour des raisons de sécurité. Le
déchiffrement de ce fichier nécessite un mot de passe, afin de pouvoir être
lu et interprété. Cependant, La suppression du mot de passe diminue le niveau de
sécurité du serveur - agissez avec précautions !</p>
    <ol>
    <li>Supprimer le chiffrement de la clé privée RSA (tout en conservant une
    copie de sauvegarde du fichier original) :<br />
       <br />
       <code><strong>$ cp server.key server.key.org</strong></code><br />
       <code><strong>$ openssl rsa -in server.key.org -out server.key</strong></code><br />

       <br />
    </li>
    <li>Assurez-vous que le fichier server.key n'est lisible que par root :<br />
       <br />
       <code><strong>$ chmod 400 server.key</strong></code><br />
       <br />
    </li>
    </ol>

    <p>Maintenant, <code>server.key</code> contient une copie non chiffrée de
    la clé. Si vous utilisez ce fichier pour votre serveur, il ne vous
    demandera plus de mot de passe. CEPENDANT, si quelqu'un arrive à obtenir
    cette clé, il sera en mesure d'usurper votre identité sur le réseau.
    Vous DEVEZ par conséquent vous assurer que seuls root ou le serveur web
    peuvent lire ce fichier (de préférence, démarrez le serveur web sous
    root et faites le s'exécuter sous un autre utilisateur, en n'autorisant
    la lecture de la clé que par root).</p>

    <p>Une autre alternative consiste à utiliser la directive
    ``<code>SSLPassPhraseDialog exec:/chemin/vers/programme</code>''. Gardez
    cependant à l'esprit que ce n'est bien entendu ni plus ni moins
    sécurisé.</p>


<h3><a name="verify" id="verify">Comment vérifier si une clé privée correspond bien
à son certificat ?</a></h3>
<p>Une clé privée contient une série de nombres. Deux de ces nombres forment la
"clé publique", les autres appartiennent à la "clé privée". Les bits de la
"clé publique" sont inclus quand vous générez une CSR, et font par
conséquent partie du certificat associé.</p>
    <p>Pour vérifier que la clé publique contenue dans votre certificat
    correspond bien à la partie publique de votre clé privée, il vous suffit
    de comparer ces nombres. Pour afficher le certificat et la clé,
    utilisez cette commande :</p>

    <p><code><strong>$ openssl x509 -noout -text -in server.crt</strong></code><br />
    <code><strong>$ openssl rsa -noout -text -in server.key</strong></code></p>

    <p>Les parties `modulus' et `public exponent' doivent être identiques dans
    la clé et le certificat. Comme le `public exponent' est habituellement
    65537, et comme il est difficile de vérifier visuellement que les nombreux
    nombres du `modulus' sont identiques, vous pouvez utiliser l'approche
    suivante :</p>

    <p><code><strong>$ openssl x509 -noout -modulus -in server.crt | openssl md5</strong></code><br />
    <code><strong>$ openssl rsa -noout -modulus -in server.key | openssl md5</strong></code></p>

    <p>Il ne vous reste ainsi que deux nombres relativement courts à comparer.
    Il est possible, en théorie que ces deux nombres soient les mêmes, sans que
    les nombres du modulus soient identiques, mais les chances en sont infimes.</p>
    <p>Si vous souhaitez vérifier à quelle clé ou certificat appartient une CSR
    particulière, vous pouvez effectuer le même calcul
    sur la CSR comme suit :</p>

    <p><code><strong>$ openssl req -noout -modulus -in server.csr | openssl md5</strong></code></p>


<h3><a name="pemder" id="pemder">Comment convertir un certificat du format PEM
au format DER ?</a></h3>
<p>Le format des certificats par défaut pour OpenSSL est le format PEM,
qui est tout simplement un format DER codé en Base64, avec des lignes
d'en-têtes et des annotations. Certaines applications, comme
Microsoft Internet Explorer, ont besoin d'un certificat au format DER de base.
Vous pouvez convertir un fichier PEM <code>cert.pem</code> en son équivalent
au format DER <code>cert.der</code> à l'aide de la commande suivante :
<code><strong>$ openssl x509 -in cert.pem -out cert.der
-outform DER</strong></code></p>


<h3><a name="gid" id="gid">Pourquoi les navigateurs se plaignent-ils de ne pas pouvoir
vérifier mon certificat de serveur ?</a></h3>

    <p>Ceci peut se produire si votre certificat de serveur est signé
    par une autorité de certification intermédiaire. Plusieurs CAs,
    comme Verisign ou Thawte, ont commencé à signer les certificats avec
    des certificats intermédiaires au lieu de leur certificat racine.</p>

    <p>Les certificats de CA intermédiaires se situe à un niveau
    intermédiaire entre le certificat racine de la CA (qui est installé dans les
    navigateurs) et le certificat du serveur (que vous avez installé sur
    votre serveur). Pour que le navigateur puisse traverser et vérifier
    la chaîne de confiance depuis le certificat du serveur jusqu'au
    certificat racine, il faut lui fournir les certificats
    intermédiaires. Les CAs devraient pouvoir fournir de tels
    paquetages de certificats intermédiaires à installer sur les
    serveurs.</p>

    <p>Vous devez inclure ces certificats intermédiaires via la
    directive <code class="directive"><a href="../mod/mod_ssl.html#sslcertificatechainfile">SSLCertificateChainFile</a></code>.</p>

<h3><a name="random" id="random">Pourquoi de nombreuses et aléatoires erreurs de
protocole SSL apparaissent-elles en cas de forte charge du serveur ?</a></h3>
<p>Ce problème peut avoir plusieurs causes, mais la principale réside dans le
cache de session SSL défini par la directive
<code class="directive"><a href="../mod/mod_ssl.html#sslsessioncache">SSLSessionCache</a></code>. Le cache de session
DBM est souvent à la source du problème qui peut être résolu en utilisant le
cache de session SHM (ou en n'utilisant tout simplement pas de cache).</p>


<h3><a name="load" id="load">Pourquoi la charge de mon serveur est-elle plus
importante depuis qu'il sert des ressources chiffrées en SSL ?</a></h3>
<p>SSL utilise un procédé de chiffrement fort qui nécessite la manipulation
d'une quantité très importante de nombres. Lorsque vous effectuez une requête
pour une page web via HTTPS, tout (même les images) est chiffré avant d'être
transmis. C'est pourquoi un accroissement du traffic HTTPS entraîne une
augmentation de la charge.</p>


<h3><a name="establishing" id="establishing">Pourquoi les connexions en HTTPS à mon serveur
prennent-elles parfois jusqu'à 30 secondes pour s'établir ?</a></h3>
<p>Ce problème provient en général d'un périphérique <code>/dev/random</code>
qui bloque l'appel système read(2) jusqu'à ce que suffisamment d'entropie
soit disponible pour servir la requête. Pour plus d'information, se référer au
manuel de référence de la directive
<code class="directive"><a href="../mod/mod_ssl.html#sslrandomseed">SSLRandomSeed</a></code>.</p>


<h3><a name="ciphers" id="ciphers">Quels sont les algorithmes de chiffrement
supportés par mod_ssl ?</a></h3>
<p>En général, tous les algorithmes de chiffrement supportés par la version
d'OpenSSL installée, le sont aussi par <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>. La liste des
algorithmes disponibles peut dépendre de la manière dont vous avez installé
OpenSSL. Typiquement, au moins les algorithmes suivants sont supportés :</p>

    <ol>
    <li>RC4 avec SHA1</li>
    <li>AES avec SHA1</li>
    <li>Triple-DES avec SHA1</li>
    </ol>

    <p>Pour déterminer la liste réelle des algorithmes disponibles, vous
    pouvez utiliser la commande suivante :</p>
    <div class="example"><p><code>$ openssl ciphers -v</code></p></div>


<h3><a name="adh" id="adh">Pourquoi une erreur ``no shared cipher'' apparaît-elle
quand j'essaie d'utiliser un algorithme de chiffrement
Diffie-Hellman anonyme (ADH) ?</a></h3>
<p>Par défaut et pour des raisons de sécurité, OpenSSl ne permet <em>pas</em>
l'utilisation des algorithmes de chiffrements ADH. Veuillez vous informer
sur les effets pervers potentiels si vous choisissez d'activer le support
de ces algorithmes de chiffrements.</p>
<p>Pour pouvoir utiliser les algorithmes de chiffrements Diffie-Hellman
anonymes (ADH), vous devez compiler OpenSSL avec
``<code>-DSSL_ALLOW_ADH</code>'', puis ajouter ``<code>ADH</code>'' à votre
directive <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code>.</p>


<h3><a name="sharedciphers" id="sharedciphers">Pourquoi une erreur ``no shared cipher''
apparaît-elle lorsqu'on se connecte à mon serveur
fraîchement installé ?</a></h3>
<p>Soit vous avez fait une erreur en définissant votre directive
<code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code> (comparez-la avec
l'exemple préconfiguré dans <code>extra/httpd-ssl.conf</code>), soit vous avez
choisi d'utiliser des algorithmes DSA/DH au lieu de RSA lorsque vous avez
généré votre clé privée, et avez ignoré ou êtes passé outre les
avertissements. Si vous avez choisi DSA/DH, votre serveur est incapable de
communiquer en utilisant des algorithmes de chiffrements SSL basés sur RSA
(du moins tant que vous n'aurez pas configuré une paire clé/certificat RSA
additionnelle). Les navigateurs modernes tels que NS ou IE ne peuvent
communiquer par SSL qu'avec des algorithmes RSA. C'est ce qui provoque l'erreur
"no shared ciphers". Pour la corriger, générez une nouvelle paire
clé/certificat pour le serveur en utilisant un algorithme de chiffrement
RSA.</p>


<h3><a name="vhosts" id="vhosts">Pourquoi ne peut-on pas utiliser SSL avec des hôtes
virtuels identifiés par un nom et non par une adresse IP ?</a></h3>
<p>La raison est très technique, et s'apparente au problème de la primauté de
l'oeuf ou de la poule. La couche du protocole SSL se trouve en dessous de la
couche de protocole HTTP qu'elle encapsule. Lors de l'établissement d'une
connexion SSL (HTTPS), Apache/mod_ssl doit négocier les paramètres du
protocole SSL avec le client. Pour cela, mod_ssl doit consulter la
configuration du serveur virtuel (par exemple, il doit accéder à la suite
d'algorithmes de chiffrement, au certificat du serveur, etc...). Mais afin de
sélectionner le bon serveur virtuel, Apache doit connaître le contenu du champ
d'en-tête HTTP <code>Host</code>. Pour cela, il doit lire l'en-tête de la
requête HTTP. Mais il ne peut le faire tant que la négociation SSL n'est pas
terminée, or, la phase de négociation SSL a besoin du nom d'hôte contenu
dans l'en-tête de la requête. Voir la question suivante pour
contourner ce problème.</p>

    <p>Notez que si votre certificat comporte un nom de serveur avec
    caractères génériques, ou des noms de serveurs multiples dans le
    champ subjectAltName, vous pouvez utiliser SSL avec les serveurs
    virtuels à base de noms sans avoir à contourner ce problème.</p>


<h3><a name="vhosts2" id="vhosts2">Est-il possible d'utiliser
l'hébergement virtuel basé sur le nom d'hôte
pour différencier plusieurs hôtes virtuels ?</a></h3>
    <p>L'hébergement virtuel basé sur le nom est une méthode très populaire
    d'identification des différents hôtes virtuels. Il permet d'utiliser la
    même adresse IP et le même numéro de port pour de nombreux sites
    différents. Lorsqu'on se tourne vers SSL, il semble tout naturel de penser
    que l'on peut appliquer la même méthode pour gérer plusieurs hôtes
    virtuels SSL sur le même serveur.</p>

    <p>C'est possible, mais seulement si on utilise une version 2.2.12
    ou supérieure du serveur web compilée avec OpenSSL
    version 0.9.8j ou supérieure. Ceci est du au fait que
    l'utilisation de l'hébergement virtuel à base de nom
    avec SSL nécessite une fonctionnalité appelée
    Indication du Nom de Serveur (Server Name Indication - SNI) que
    seules les révisions les plus récentes de la
    spécification SSL supportent.</p>

    <p>Notez que si votre certificat comporte un nom de serveur avec
    caractères génériques, ou des noms de serveurs multiples dans le
    champ subjectAltName, vous pouvez utiliser SSL avec les serveurs
    virtuels à base de noms sans avoir à contourner ce problème.</p>

    <p>La raison en est que le protocole SSL constitue une couche séparée qui
    encapsule le protocole HTTP. Aini, la session SSL nécessite une
    transaction séparée qui prend place avant que la session HTTP n'ait débuté.
    Le serveur reçoit une requête SSL sur l'adresse IP X et le port Y
    (habituellement 443). Comme la requête SSL ne contenait aucun
    en-tête Host:, le serveur n'avait aucun moyen de déterminer quel hôte virtuel SSL il
    devait utiliser. En général, il utilisait le premier
    qu'il trouvait et qui
    correspondait à l'adresse IP et au port spécifiés.</p>

    <p>Par contre, si vous utilisez des versions du serveur web et
    d'OpenSSL qui supportent SNI, et si le navigateur du client le
    supporte aussi, alors le nom d'hôte sera inclus dans la
    requête SSL originale, et le serveur web pourra
    sélectionner le bon serveur virtuel SSL.</p>

    <p>Bien entendu, vous pouvez utiliser l'hébergement virtuel basé sur le nom
    pour identifier de nombreux hôtes virtuels non-SSL
    (tous sur le port 80 par exemple), et ne gérer qu'un seul hôte virtuel SSL
    (sur le port 443). Mais dans ce cas, vous devez définir le numéro de port
    non-SSL à l'aide de la directive NameVirtualHost dans ce style :</p>

    <pre class="prettyprint lang-config">NameVirtualHost 192.168.1.1:80</pre>


    <p>il existe d'autres solutions alternatives comme :</p>

    <p>Utiliser des adresses IP différentes pour chaque hôte SSL.
    Utiliser des numéros de port différents pour chaque hôte SSL.</p>


<h3><a name="comp" id="comp">Comment mettre en oeuvre la compression SSL ?</a></h3>
<p>Bien que la négociation pour la compression SSL ait été définie dans la
spécification de SSLv2 et TLS, ce n'est qu'en mai 2004 que la RFC 3749 a
défini DEFLATE comme une méthode de compression standard négociable.
</p>
<p>Depuis la version 0.9.8, OpenSSL supporte cette compression par défaut
lorsqu'il est compilé avec l'option <code>zlib</code>. Si le client et le
serveur supportent la compression, elle sera utilisée. Cependant, la
plupart des clients essaient encore de se connecter avec un Hello SSLv2.
Comme SSLv2 ne comportait pas de table des algorithmes de compression préférés
dans sa négociation, la compression ne peut pas être négociée avec ces clients.
Si le client désactive le support SSLv2, un Hello SSLv3 ou TLS peut être
envoyé, selon la bibliothèque SSL utilisée, et la compression peut être mise
en oeuvre. Vous pouvez vérifier si un client utilise la compression SSL en
journalisant la variable <code>%{SSL_COMPRESS_METHOD}x</code>.
</p>


<h3><a name="lockicon" id="lockicon">Lorsque j'utilise l'authentification de base sur HTTPS,
l'icône de verrouillage des navigateurs Netscape reste ouverte quand la boîte
de dialogue d'authentification apparaît. Cela signifie-t-il que les utilisateur
et mot de passe sont envoyés en clair ?</a></h3>
<p>Non, le couple utilisateur/mot de passe est transmis sous forme chiffrée.
	L'icône de chiffrement dans les navigateurs Netscape n'est pas vraiment
	synchronisé avec la couche SSL/TLS. Il ne passe à l'état verrouillé
	qu'au moment où la première partie des données relatives à la page web
	proprement dite sont transférées, ce qui peut prêter à confusion. Le
	dispositif d'authentification de base appartient à la couche HTTP, qui
	est située au dessus de la couche SSL/TLS dans HTTPS. Avant tout
	transfert de données HTTP sous HTTPS, la couche SSL/TLS a déjà achevé
	sa phase de négociation et basculé dans le mode de communication
	chiffrée. Ne vous laissez donc pas abuser par l'état de cet icône.</p>


<h3><a name="msie" id="msie">Pourquoi des erreurs d'entrée/sortie apparaissent-elles
lorsqu'on se connecte via HTTPS à un serveur Apache+mod_ssl avec des
versions anciennes de
Microsoft Internet Explorer (MSIE) ?</a></h3>
<p>La première raison en est la présence dans l'implémentation SSL de
certaines versions de MSIE de bogues subtils en rapport avec le
dispositif de "maintien en vie" (keep-alive) HTTP, et les alertes de
notification de fermeture de session SSL en cas de coupure de la
connexion au point d'entrée (socket). De plus, l'interaction entre
SSL et les fonctionnalités HTTP/1.1 pose problème avec certaines
versions de MSIE. Vous pouvez contourner ces problèmes en interdisant
à Apache l'utilisation de HTTP/1.1, les connexions avec maintien en vie
ou l'envoi de messages de notification de fermeture de session SSL aux
clients MSIE. Pour cela, vous pouvez utiliser la directive suivante
dans votre section d'hôte virtuel avec support SSL :</p>
    <pre class="prettyprint lang-config">SetEnvIf User-Agent "MSIE [2-5]" \
         nokeepalive ssl-unclean-shutdown \
         downgrade-1.0 force-response-1.0</pre>

    <p>En outre, certaines versions de MSIE ont des problèmes avec des
    algorithmes de chiffrement particuliers. Hélas, il n'est pas
    possible d'apporter une solution spécifique à MSIE pour ces
    problèmes, car les algorithmes de chiffrement sont utilisés dès la
    phase de négociation SSL. Ainsi, une directive
    <code class="directive"><a href="../mod/mod_setenvif.html#setenvif">SetEnvIf</a></code> spécifique
    à MSIE ne peut être d'aucun secours. Par contre, vous devrez
    ajuster les paramètres généraux de manière drastique. Avant de
    vous décider, soyez sûr que vos clients rencontrent vraiment des
    problèmes. Dans la négative, n'effectuez pas ces ajustements car
    ils affecteront <em>tous</em> vos clients, ceux utilisant MSIE,
    mais aussi les autres.</p>



<h3><a name="srp" id="srp">Comment activer TLS-SRP ?</a></h3>
    <p>Le protocole TLS-SRP (Echange de clés sécurisé par mot de passe
    pour TLS comme spécifié dans la RFC 5054) peut compléter ou même
    remplacer les certificats lors du processus d'authentification des
    connexions SSL. Pour utiliser TLS-SRP, spécifiez un fichier de
    vérification SRP OpenSSL via la directive <code class="directive"><a href="../mod/mod_ssl.html#sslsrpverifierfile">SSLSRPVerifierFile</a></code>. Vous pouvez créer
    le fichier de vérification via l'utilitaire <code>openssl</code> :</p>
    <div class="example"><p><code>
    openssl srp -srpvfile passwd.srpv -add username
    </code></p></div>
    <p>Une fois ce fichier créé, vous devez le référencer dans la
    configuration du serveur SSL :</p>
    <div class="example"><p><code>
    SSLSRPVerifierFile /path/to/passwd.srpv
    </code></p></div>
    <p>Pour forcer les clients à utiliser des algorithmes de chiffrement
    basés sur TLS-SRP et s'affranchissant des certificats, utilisez la
    directive suivante :</p>
    <div class="example"><p><code>
    SSLCipherSuite "!DSS:!aRSA:SRP"
    </code></p></div>


<h3><a name="javadh" id="javadh">Pourquoi des erreurs de négociation apparaissent
avec les clients basés sur Java lorsqu'on utilise un certificat de plus
de 1024 bits ?</a></h3>
    <p>Depuis la version 2.4.7,
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> utilise des paramètres DH qui comportent
    des nombres premiers de plus de 1024 bits. Cependant, java 7 et ses versions
    antérieures ne supportent que les nombres premiers DH d'une longueur
    maximale de 1024 bits.</p>

    <p>Si votre client basé sur Java s'arrête avec une exception telle
    que <code>java.lang.RuntimeException: Could not generate DH
    keypair</code> et
    <code>java.security.InvalidAlgorithmParameterException: Prime size
    must be multiple of 64, and can only range from 512 to 1024
    (inclusive)</code>, et si httpd enregistre le message <code>tlsv1
    alert internal error (SSL alert number 80)</code> dans son journal
    des erreurs (avec un <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code>
    <code>info</code> ou supérieur), vous pouvez soit réarranger la
    liste d'algorithmes de mod_ssl via la directive <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code> (éventuellement en
    conjonction avec la directive <code class="directive"><a href="../mod/mod_ssl.html#sslhonorcipherorder">SSLHonorCipherOrder</a></code>), soit utiliser des
    paramètres DH personnalisés avec un nombre
    premier de 1024 bits, paramètres qui seront toujours prioritaires
    par rapport à tout autre paramètre DH par défaut.</p>

    <p>Pour générer des paramètres DH personnalisés, utilisez la
    commande <code>openssl dhparam 1024</code>. Vous pouvez aussi
    utiliser les
    paramètres DH standards issus de la <a href="http://www.ietf.org/rfc/rfc2409.txt">RFC 2409</a>, section 6.2 :</p>
    <div class="example"><pre>-----BEGIN DH PARAMETERS-----
MIGHAoGBAP//////////yQ/aoiFowjTExmKLgNwc0SkCTgiKZ8x0Agu+pjsTmyJR

    <p>Ajoute les paramètres personnalisés incluant les lignes "BEGIN DH

    </li>
    </ol>


<h3><a name="reportdetails" id="reportdetails">Quelles informations dois-je fournir lors
de l'écriture d'un rapport de bogue ?</a></h3>
<p>Vous devez toujours fournir au moins les informations
suivantes :</p>

    <dl>
    <dt>Les versions d'Apache httpd et OpenSSL installées</dt>
    <dd>La version d'Apache peut être déterminée en exécutant
    <code>httpd -v</code>. La version d'OpenSSL peut être déterminée
    en exécutant <code>openssl version</code>. Si Lynx est installé,
    vous pouvez aussi exécuter la commande<code>lynx -mime_header
    http://localhost/ | grep Server</code> et ainsi obtenir ces
    informations en une seule fois.
    </dd>

    <dt>Les détails de votre installation d'Apache httpd et OpenSSL</dt>
    <dd>A cet effet, vous pouvez fournir un fichier journal de votre
    session de terminal qui montre les étapes de la configuration et
    de l'installation. En cas d'impossibilité, vous devez au moins
    fournir la ligne de commande <code class="program"><a href="../programs/configure.html">configure</a></code> que
    vous avez utilisée.
    </dd>

    <dt>En cas de vidage mémoire, inclure une trace de ce qui s'est
    passé</dt>
    <dd>Si votre serveur Apache httpd fait un vidage de sa
    mémoire, merci de fournir en pièce jointe un fichier contenant
    une trace de la zone dédiée à la pile (voir
    <a href="#backtrace">ci-dessous</a> pour des informations sur la manière
    de l'obtenir). Il est nécessaire de disposer de ces informations
    afin de pouvoir déterminer la raison de votre vidage mémoire.
    </dd>

    <dt>Une description détaillée de votre problème</dt>

    <dd>Ne riez pas, nous sommes sérieux ! De nombreux rapports
    n'incluent pas de description de la véritable nature du problème.
    Sans ces informations, il est très difficile pour quiconque de
    vous aider. Donc, et c'est votre propre intérêt (vous souhaitez
    que le problème soit résolu, n'est-ce pas ?), fournissez, s'il vous
    plait, le maximum de détails possible. Bien entendu, vous devez
    aussi inclure tout ce qui a été dit précédemment.
    </dd>
    </dl>


<h3><a name="coredumphelp" id="coredumphelp">Un vidage mémoire s'est produit,
pouvez-vous m'aider ?</a></h3>
<p>En général non, du moins tant que vous n'aurez pas fourni plus de
détails à propos de la localisation dans le code où Apache a effectué
son vidage mémoire. Ce dont nous avons en général besoin pour vous
aider est une trace de ce qui s'est passé (voir la question suivante).
Sans cette information, il est pratiquement impossible de déterminer
la nature du problème et de vous aider à le résoudre.</p>


<h3><a name="backtrace" id="backtrace">Comment puis-je obtenir une journalisation de
ce qui s'est passé, pour m'aider à trouver la raison de ce vidage
mémoire ?</a></h3>
<p>Vous trouverez ci-dessous les différentes étapes permettant
d'obtenir une journalisation des évènements (backtrace) :</p>
    <ol>
    <li>Assurez-vous que les symboles de débogage sont disponibles, au
    moins pour Apache. Pour cela, sur les plates-formes où GCC/GDB est
    utilisé, vous devez compiler Apache+mod_ssl avec l'option
    ``<code>OPTIM="-g -ggdb3"</code>''. Sur les autres plates-formes,
    l'option ``<code>OPTIM="-g"</code>'' est un minimum.
    </li>

    <li>Démarrez le serveur et essayez de reproduire le vidage mémoire.
    A cet effet, vous pouvez utiliser une directive du style
    ``<code>CoreDumpDirectory /tmp</code>'' pour être sûr que le
    fichier de vidage mémoire puisse bien être écrit. Vous devriez
    obtenir un fichier <code>/tmp/core</code> ou
    <code>/tmp/httpd.core</code>. Si ce n'est pas le cas, essayez de
    lancer votre serveur sous un UID autre que root.
    Pour des raisons de sécurité, de nombreux
    noyaux modernes de permettent pas à un processus de vider sa
    mémoire une fois qu'il a accompli un <code>setuid()</code> (à moins
    qu'il effectue un <code>exec()</code>) car des informations d'un
    niveau privilégié pourraient être transmises en mémoire. Si
    nécessaire, vous pouvez exécuter <code>/chemin/vers/httpd -X</code>
    manuellement afin de ne pas permettre à Apache de se clôner (fork).
    </li>

    <li>Analysez le vidage mémoire. Pour cela, exécutez
    <code>gdb /path/to/httpd /tmp/httpd.core</code> ou une commande
    similaire. Dans GDB, tout ce que vous avez à faire est d'entrer
    <code>bt</code>, et voila, vous obtenez la backtrace. Pour les
    débogueurs autres que GDB consulter le manuel correspondant.
    </li>
    </ol>

<p>
This page covers backwards compatibility between mod_ssl and other
SSL solutions.  mod_ssl is not the only SSL solution for Apache; four
additional products are (or were) also available: Ben Laurie's freely
available <a href="http://www.apache-ssl.org/">Apache-SSL</a> (from
where mod_ssl were originally derived in 1998), Red Hat's commercial
Secure Web Server (which was based on mod_ssl), Covalent's commercial
Raven SSL Module (also based on
mod_ssl) and finally C2Net's (now Red Hat's) commercial product <a href="http://www.redhat.com/explore/stronghold/">Stronghold</a> (based
on a different evolution branch, named Sioux up to Stronghold 2.x, and
based on mod_ssl since Stronghold 3.x).</p>

<p>
mod_ssl mostly provides a superset of the functionality of all the other
solutions, so it's simple to migrate from one of the older modules to
mod_ssl. The configuration directives and environment variable names
used by the older SSL solutions vary from those used in mod_ssl;
mapping tables are included here to give the equivalents used by mod_ssl.</p>

<h3><a name="onlystrong" id="onlystrong">Comment créer un serveur SSL qui n'accepte

    <pre class="prettyprint lang-config">SSLCipherSuite HIGH:!aNULL:!MD5</pre>


 <p>Avec la configuration qui suit, vous indiquez une préférence pour
 des algorityhmes de chiffrement spécifiques optimisés en matière de
 rapidité (le choix final sera opéré par mod_ssl, dans la mesure ou le

    <pre class="prettyprint lang-config">SSLCipherSuite RC4-SHA:AES128-SHA:HIGH:!aNULL:!MD5

<h3><a name="strongurl" id="strongurl">Comment créer un serveur qui accepte tous les types de

    <p>Dans ce cas bien évidemment, une directive <code class="directive"><a href="../mod/mod_ssl.html#sslciphersuite">SSLCipherSuite</a></code> au niveau du serveur principal
    qui restreint le choix des suites de chiffrement aux versions les plus
    fortes ne conviendra pas. <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> peut cependant être
    reconfiguré au sein de blocs <code>Location</code> qui permettent
    d'adapter la configuration générale à un répertoire spécifique ;
    <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> peut alors forcer automatiquement une
    renégociation des paramètres SSL pour parvenir au but recherché.
    Cette configuration peut se présenter comme suit :</p>
    <pre class="prettyprint lang-config"># soyons très tolérant a priori

&lt;Location "/strong/area"&gt;

<div class="section">
<h2><a name="ocspstapling" id="ocspstapling">Agrafage OCSP</a></h2>


<p>Le protocole de contrôle du statut des certificats en ligne (Online
Certificate Status Protocol - OCSP) est un mécanisme permettant de
déterminer si un certificat a été révoqué ou non, et l'agrafage OCSP en
est une fonctionnalité particulière par laquelle le serveur, par exemple
httpd et mod_ssl, maintient une liste des réponses OCSP actuelles pour
ses certificats et l'envoie aux clients qui communiquent avec lui. La
plupart des certificats contiennent l'adresse d'un répondeur OCSP maintenu
par l'Autorité de Certification (CA) spécifiée, et mod_ssl peut requérir
ce répondeur pour obtenir une réponse signée qui peut être envoyée aux
clients qui communiquent avec le serveur.</p>

<p>L'agrafage OCSP est la méthode la plus performante pour obtenir le
statut d'un certificat car il est disponible au niveau du serveur, et le
client n'a donc pas besoin d'ouvrir une nouvelle connexion vers
l'autorité de certification. Autres avantages de l'absence de
communication entre le client et l'autorité de certification :
l'autorité de certification n'a pas accès à l'historique de navigation
du client, et l'obtention du statut du certificat est plus efficace car
elle n'est plus assujettie à une surcharge éventuelle des serveurs de
l'autorité de certification.</p>

<p>La charge du serveur est moindre car la réponse qu'il a obtenu du
répondeur OCSP peut être réutilisée par tous les clients qui utilisent
le même certificat dans la limite du temps de validité de la réponse.</p>

<p>Une fois le support général SSL correctement configuré, l'activation
de l'agrafage OCSP ne requiert que des modifications mineures
à la configuration de httpd et il suffit en général de l'ajout de ces
deux directives :</p>

    <pre class="prettyprint lang-config">SSLUseStapling On
SSLStaplingCache "shmcb:ssl_stapling(32768)"</pre>


<p>Ces directives sont placées de façon à ce qu'elles aient une portée
globale (et particulièrement en dehors de toute section VirtualHost), le
plus souvent où sont placées les autres directives de configuration
globales SSL, comme <code>conf/extra/httpd-ssl.conf</code> pour les
installations de httpd à partir des sources, ou
<code>/etc/apache2/mods-enabled/ssl.conf</code> pour Ubuntu ou Debian,
etc...</p>

<p>Le chemin spécifié par la directive
<code class="directive">SSLStaplingCache</code> (par exemple <code>logs/</code>)
doit être le même que celui spécifié par la directive
<code class="directive">SSLSessionCache</code>. Ce chemin est relatif au chemin
spécifié par la directive <code class="directive">ServerRoot</code>.</p>

<p>Cette directive <code class="directive">SSLStaplingCache</code> particulière
nécessite le chargement du module <code class="module"><a href="../mod/mod_socache_shmcb.html">mod_socache_shmcb</a></code> (à
cause du préfixe <code>shmcb</code> de son argument). Ce module est en
général déjà activé pour la directive
<code class="directive">SSLSessionCache</code>, ou pour des modules autres que
<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>. Si vous activez un cache de session SSL
utilisant un mécanisme autre que <code class="module"><a href="../mod/mod_socache_shmcb.html">mod_socache_shmcb</a></code>,
utilisez aussi ce mécanisme alternatif pour la directive
<code class="directive">SSLStaplingCache</code>. Par exemple :</p>

    <pre class="prettyprint lang-config">SSLSessionCache "dbm:ssl_scache"
SSLStaplingCache "dbm:ssl_stapling"</pre>


<p>Vous pouvez utiliser la commande openssl pour vérifier que votre
serveur envoie bien une réponse OCSP :</p>

<pre>$ openssl s_client -connect www.example.com:443 -status -servername www.example.com
...
OCSP response: 
======================================
OCSP Response Data:
    OCSP Response Status: successful (0x0)
    Response Type: Basic OCSP Response
...
    Cert Status: Good
...</pre>

<p>Les sections suivantes explicitent les situations courantes qui
requièrent des modifications supplémentaires de la configuration. Vous
pouvez aussi vous référer au manuel de référence de
<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>.</p>

<h3>Si l'on utilise plus que quelques certificats SSL pour le serveur</h3>

<p>Les réponses OCSP sont stockées dans le cache d'agrafage SSL. Alors
que les réponses ont une taille de quelques centaines à quelques
milliers d'octets, mod_ssl supporte des réponses d'une taille jusqu'à
environ 10 ko. Dans notre cas, le nombre de certificats est conséquent
et la taille du cache (32768 octets dans l'exemple ci-dessus) doit être
augmentée. En cas d'erreur lors du stockage d'une réponse, le
message AH01929 sera enregistré dans le journal.</p>


<h3>Si le certificat ne spécifie pas de répondeur OCSP, ou si une
adresse différente doit être utilisée</h3>

<p>Veuillez vous référer à la documentation de la directive <code class="directive"><a href="../mod/mod_ssl.html#sslstaplingforceurl">SSLStaplingForceURL</a></code>.</p>

<p>Vous pouvez vérifier si un certificat spécifie un répondeur OCSP en
utilisant la commande openssl comme suit :</p>

<pre>$ openssl x509 -in ./www.example.com.crt -text | grep 'OCSP.*http'
OCSP - URI:http://ocsp.example.com</pre>

<p>Si un URI OCSP est fourni et si le serveur web peut communiquer
directement avec lui sans passer par un mandataire, aucune modification
supplémentaire de la configuration n'est requise. Notez que les règles
du pare-feu qui contrôlent les connexions sortantes en provenance du
serveur web devront peut-être subir quelques ajustements.</p>

<p>Si aucun URI OCSP n'est fourni, contactez votre autorité de
certification pour savoir s'il en existe une ; si c'est le
cas, utilisez la directive <code class="directive"><a href="../mod/mod_ssl.html#sslstaplingforceurl">SSLStaplingForceURL</a></code> pour la spécifier dans
la configuration du serveur virtuel qui utilise le certificat.</p>


<h3>Si plusieurs serveurs virtuels sont configurés pour utiliser SSL

<p>Ajoutez la directive <code>SSLUseStapling Off</code> à la

être désactivé.</p>


<h3>Si le répondeur OCSP est lent ou instable</h3>

<p>De nombreuses directives permettent de gérer les temps de réponse et

<pre>AH02217: ssl_stapling_init_cert: Can't retrieve issuer certificate!</pre>
<p>Afin de pouvoir supporter l'agrafage OCSP lorsqu'un certificat de
serveur particulier est utilisé, une chaîne de certification pour ce

<h3><a name="allclients" id="allclients">Comment forcer les clients
à s'authentifier à l'aide de certificats ?
</a></h3>


    <p>Lorsque vous connaissez tous vos clients (comme c'est en général le cas
    au sein d'un intranet d'entreprise), vous pouvez imposer une
    authentification basée uniquement sur les certificats. Tout ce dont vous
    avez besoin pour y parvenir est de créer des certificats clients signés par
    le certificat de votre propre autorité de certification
    (<code>ca.crt</code>), et d'authentifier les clients à l'aide de ces
    certificats.</p>
    <pre class="prettyprint lang-config"># exige un certificat client signé par le certificat de votre CA
# contenu dans ca.crt
SSLVerifyClient require
SSLVerifyDepth 1
SSLCACertificateFile "conf/ssl.crt/ca.crt"</pre>



<h3><a name="arbitraryclients" id="arbitraryclients">Comment forcer les clients
à s'authentifier à l'aide de certificats pour une URL particulière,
mais autoriser quand-même tout client anonyme
à accéder au reste du serveur ?</a></h3>


<p>Pour forcer les clients à s'authentifier à l'aide de certificats pour une
URL particulière, vous pouvez utiliser les fonctionnalités de reconfiguration
de <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> en fonction du répertoire :</p>

    <pre class="prettyprint lang-config">SSLVerifyClient none
SSLCACertificateFile "conf/ssl.crt/ca.crt"

&lt;Location "/secure/area"&gt;
SSLVerifyClient require
SSLVerifyDepth 1
&lt;/Location&gt;</pre>



<h3><a name="certauthenticate" id="certauthenticate">Comment n'autoriser l'accès à une URL
particulière qu'aux clients qui possèdent des certificats, mais autoriser
l'accès au reste du serveur à tous les clients ?</a></h3>


    <p>La clé du problème consiste à vérifier si une partie du certificat
    client correspond à ce que vous attendez. Cela signifie en général
    consulter tout ou partie du nom distinctif (DN), afin de vérifier s'il
    contient une chaîne connue. Il existe deux méthodes pour y parvenir ;
    on utilise soit le module <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>, soit la
    directive <code class="directive"><a href="../mod/mod_ssl.html#sslrequire">SSLRequire</a></code>.</p>

    <p>La méthode du module <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> est en général
    incontournable lorsque les certificats ont un contenu arbitraire, ou
    lorsque leur DN ne contient aucun champ connu
    (comme l'organisation, etc...). Dans ce cas, vous devez construire une base
    de données de mots de passe contenant <em>tous</em> les clients
    autorisés, comme suit :</p>

    <pre class="prettyprint lang-config">SSLVerifyClient      none
SSLCACertificateFile "conf/ssl.crt/ca.crt"
SSLCACertificatePath "conf/ssl.crt"

&lt;Directory "/usr/local/apache2/htdocs/secure/area"&gt;
SSLVerifyClient      require
    SSLVerifyDepth       5
    SSLOptions           +FakeBasicAuth
    SSLRequireSSL
    AuthName             "Snake Oil Authentication"
    AuthType             Basic
    AuthBasicProvider    file
    AuthUserFile         "/usr/local/apache2/conf/httpd.passwd"
    Require              valid-user
&lt;/Directory&gt;</pre>

    

    <p>Le mot de passe utilisé dans cet exemple correspond à la chaîne de
    caractères "password" chiffrée en DES. Voir la documentation de la
    directive <code class="directive"><a href="../mod/mod_ssl.html#ssloptions">SSLOptions</a></code> pour
    plus de détails.</p>

    <div class="example"><h3>httpd.passwd</h3><pre>/C=DE/L=Munich/O=Snake Oil, Ltd./OU=Staff/CN=Foo:xxj31ZMTZzkVA
/C=US/L=S.F./O=Snake Oil, Ltd./OU=CA/CN=Bar:xxj31ZMTZzkVA
/C=US/L=L.A./O=Snake Oil, Ltd./OU=Dev/CN=Quux:xxj31ZMTZzkVA</pre></div>

    <p>Lorsque vos clients font tous partie d'une même hiérarchie, ce qui
    apparaît dans le DN, vous pouvez les authentifier plus facilement en
    utilisant la directive <code class="directive"><a href="../mod/mod_ssl.html#sslrequire">SSLRequire</a></code>, comme suit :</p>


    <pre class="prettyprint lang-config">SSLVerifyClient      none
SSLCACertificateFile "conf/ssl.crt/ca.crt"
SSLCACertificatePath "conf/ssl.crt"

&lt;Directory "/usr/local/apache2/htdocs/secure/area"&gt;
  SSLVerifyClient      require
  SSLVerifyDepth       5
  SSLOptions           +FakeBasicAuth
  SSLRequireSSL
  SSLRequire       %{SSL_CLIENT_S_DN_O}  eq "Snake Oil, Ltd." \
               and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"}
&lt;/Directory&gt;</pre>

<h2><a name="cryptographictech" id="cryptographictech">暗号化技術</a></h2>

<p>SSL を理解するには、暗号アルゴリズム、
メッセージダイジェスト関数(別名: 一方向関数、ハッシュ関数)、
電子署名などへの理解が必要です。
これらの技術は本が丸ごと必要な題目で
(例えば [<a href="#AC96">AC96</a>] を参照)、
プライバシー、信用、認証などの技術の基礎となっています。</p>

<h3><a name="cryptographicalgo" id="cryptographicalgo">暗号アルゴリズム</a></h3>

    <p>例えば、アリスが送金のために銀行にメッセージを送りたいとします。
    口座番号や送金の金額が含まれるため、
    アリスはそのメッセージを秘密にしたいと思います。
    解決方法の一つは暗号アルゴリズムを使って、メッセージを
    復号されるまで読むことができない暗号化された
    形態に変えてしまうことです。
    その形態になると、
    メッセージは秘密の鍵によってのみ復号化することができます。
    鍵なしでは、メッセージは役に立ちません。
    良い暗号アルゴリズムは、侵入者が元のテキストを解読することを
    非常に難しくするため、努力が割に合わなくさせます。</p>

    <p>暗号アルゴリズムには
    従来型と公開鍵の二つの種類があります。</p>

    <dl>
    <dt>従来型暗号</dt>
    <dd>対称暗号としても知られ、
    送信者と受信者が鍵を共有することが必要です。
    鍵とは、メッセージを暗号化したり復号するのに使われる秘密
    の情報のことです。
    この鍵が秘密になっている限り、送信者と受信者以外は誰もメッセージを読
    むことができません。
    もしも、アリスと銀行が秘密の鍵を知っているなら、
    彼らはお互いに秘密のメッセージを送ることができるでしょう。
    ただし交信の前に、事前に内密に鍵を共有するという作業自体は難題かもしれません。</dd>

    <dt>公開鍵暗号</dt>
    <dd>非対称暗号としても知られ、
    メッセージを暗号化することのできる二つの鍵
    を使用するアルゴリズムを定義することで鍵のやり取りの問題を解決
    します。
    もし、ある鍵が暗号化に使われたなら、
    もう片方の鍵で復号しなければいけません。
    この方式によって、一つの鍵を公表して(公開鍵)、
    もう片方を秘密にしておく(秘密鍵)だけで、
    安全なメッセージを受け取ることができます。</dd>
    </dl>

    <p>公開鍵を使って誰もがメッセージを暗号化できますが、秘
    密鍵の持ち主だけがそれを読むことができます。
    この方法で、銀行の公開鍵を使って暗号化することで、
    アリスは秘密のメッセージを送ることができます。
    銀行のみが送られたメッセージを復号することができます。</p>


<h3><a name="messagedigests" id="messagedigests">メッセージダイジェスト</a></h3>

    <p>アリスはメッセージを秘密にすることができますが、
    誰かが例えば自分に送金するようにメッセージを変更したり、
    別のものに置き換えてしまうかもしれないという問題があります。
    アリスのメッセージだという信憑性を保証する方法の一つは、
    メッセージの簡潔なダイジェストを作って、それも銀行に送るというものです。
    メッセージを受け取ると銀行側でもダイジェストを作成し、
    アリスが送ったダイジェストと比べます。もし一致したなら、
    受け取ったメッセージは無傷だということになります。</p>

    <p>このような要約は<dfn>メッセージダイジェスト</dfn>、
    <em>一方行関数</em>、または<em>ハッシュ関数</em>と呼ばれます。
    メッセージダイジェストは長い可変長のメッセージから
    短い固定長の表現を作るのに使われます。
    ダイジェストアルゴリズムはメッセージから
    一意なダイジェストを生成するように作られています。
    メッセージダイジェストはダイジェストから元のメッセージを
    判定するのがとても難しいようにできていて、
    同じ要約を作成する二つのメッセージを探すのは(理論上)不可能です。
    これによって、要約を変更することなくメッセージを置き換えられる
    可能性を排除しています。</p>

    <p>アリスへのもう一つの問題は、このダイジェストを安全に送る方法を探すことです。
    ダイジェストが安全に送られればダイジェストの信憑性が保障されて、
    ダイジェストの信憑性をもってオリジナルメッセージの信憑性を得ることができます。
    ダイジェストを安全に送った場合にのみ、そのメッセージの
    信憑性が得られます。</p>

    <p>ダイジェスト安全に送る方法の一つは、電子署名に含める方法です。</p>


<h3><a name="digitalsignatures" id="digitalsignatures">電子署名</a></h3>
<p>アリスが銀行にメッセージを送ったとき、
侵入者が彼女になりすまして彼女の口座への取引を申請できないように、
銀行側ではメッセージが本当に彼女からのものか確実に分かるようにしなければなりません。
アリスによって作成されて、メッセージに含まれた
<em>電子署名</em>がここで役に立ちます。</p>

<p>電子署名はメッセージのダイジェストやその他の情報(処理番号など)を
送信者の秘密鍵で暗号化することで作られます。
誰もが公開鍵を使って署名を<em>復号</em>することができますが、
送信者のみが秘密鍵を知っています。
これは送信者のみが署名しえたことを意味します。
ダイジェストを電子署名に含むことは、
その署名がそのメッセージのみに有効であることを意味します。
これは、誰もダイジェストを変えて署名をすることができないため、
メッセージの信用も保証します。</p>

<p>侵入者が署名を傍受して後日に再利用するのを防ぐため
電子署名には一意な処理番号が含まれます。
これは、アリスがそんなメッセージは送っていないと言う詐欺
から銀行を守ります。
彼女だけが署名しえたからです。(否認防止)</p>

<p>アリスは秘密のメッセージを銀行に送り、
署名をして、メッセージの信用を保証することができるおうになりましたが、
通信している相手が本当に銀行なのか確かめなくてはいけません。
つまり彼女が使おうとしている公開鍵が、銀行の秘密鍵と対になっていて、
侵入者の秘密鍵と対になっているわけではないことを
確かめなくてはいけないことを意味しています。
同様に銀行は、メッセージの署名が本当にアリスの持っている
秘密鍵で署名された署名かを確認する必要があります。</p>

<p>もし両者に身元を証明し、公開鍵を確認し、また信頼された機関が署名
した証明書があれば、両者とも通信相手について正しい相手だと
確信することができます。
そのような信頼された機関は<em>認証局</em>
 (Certificate Authority または CA) と呼ばれ、
証明書 (certificate) が認証 (authentication) に使われます。</p>

<h3><a name="certificatecontents" id="certificatecontents">証明書の内容</a></h3>

    <p>証明書は公開鍵と個人、サーバ、その他の主体の実在の身元を
    関連付けます。
    <a href="#table1">表1</a>に示されるように証明対象の情報は
    身元証明の情報(識別名)と公開鍵が含まれます。
    証明書はまた、認証局の身元証明と署名、そして証明書の有効期間を
    含みます。
    シリアルナンバーなどの認証局の管理上の情報や
    その他の追加の情報が含まれているかもしれません。</p>

    <p>識別名(ディスティングイッシュ・ネーム)は特定の状況における
    身分証明を提供するのに使われています。例えば、ある人は
    私用と会社とで別々の身分証明を持つかもしれません。
    
    識別名は X.509 標準規格 [<a href="#X509">X509</a>] で定義されています。
    X.509 標準規格は、項目、項目名、そして項目の略称を定義しています。(<a href="#table2">表

    <p>認証局はどの項目が省略可能でどれが必須かの方針を定義する
    かもしれません。項目の内容についても認証局や証明書のユーザからの
    要件があるかもしれません。
    例えばネットスケープのブラウザは、サーバの証明書の
     Common Name (コモンネーム)がサーバのドメイン名の
     <code>*.snakeoil.com</code> 
    というようなワイルドカードのパターンにマッチすること

    <p>バイナリ形式の証明書は ASN.1 表記法
     [<a href="#X208">X208</a>] [<a href="#PKCS">PKCS</a>] で
    定義されています。
    この表記法は内容をどのように記述するかを定義し、
    符号化の規定がこの情報がどのようにバイナリ形式に変換されるかを
    定義します。
    証明書のバイナリ符号化は Distinguished Encoding
    Rules (DER) で定義され、それはより一般的な Basic Encoding Rules
    (BER) に基づいています。
    バイナリ形式を扱うことのできない送信では、
    バイナリ形式は Base64 符号化 [<a href="#MIME">MIME</a>] で
    ASCII 形式に変換されることがあります。
    開始デリミタ行と終了デリミタ行で囲まれた、この形式のことを
    PEM ("Privacy Enhanced Mail") 符号化された証明書と言います。</p>

<h3><a name="certificateauthorities" id="certificateauthorities">認証局</a></h3>

    <p>証明書を承認する前に、証明書要求に記載されている情報を確認し、
    認証局は鍵の所有者の身元を確認します。
    例えば、アリスが個人証明書を申請したとすると、
    認証局はアリスが証明書の申請が主張する通りの
    当の本人だということを確認しなくてはいけません。</p>

    <h4><a name="certificatechains" id="certificatechains">証明書の連鎖</a></h4>
    
        <p>認証局は他の認証局への証明書を発行することができます。
        未知の証明書を調べる時に、アリスはその証明書の発行者
        に自信が持てるまで、発行者の証明書を
        その上位階層の認証局をたどって調べる必要があります。
        「悪質な」証明書の危険性を減らすため、
        彼女は限られた連鎖の発行者のみ信頼するように
        決めることもできます。</p>
    

    <h4><a name="rootlevelca" id="rootlevelca">最上位認証局の作成</a></h4>
    
        <p>前に述べたように、全ての証明書について、
        最上位の認証局(CA)までそれぞれの発行者が
        対象の身元証明の有効性を明らかにする必要があります。
        問題は、誰がその最上位の認証機関の証明書を保証するのか、
        ということです。
        このような場合に限り、証明書は「自己署名」されます。
        ブラウザには、とてもよく知られている認証局が初期登録されていますが、
        自己署名された証明書を信用する際には
        細心の注意が必要です。
        最上位認証局が公開鍵を広く公表することで、
        その鍵を信頼するリスクを低くすることができます。
        もし、他人がその認証局になりすました時に、それが露見しや
        すいからです。</p>

        <p><a href="http://www.thawte.com/">Thawte</a> 
        や <a href="http://www.verisign.com/">VeriSign</a> 
        のような多くの会社が認証局として開設しました。
        このような会社は以下のサービスを提供します:</p>

        <ul>
        <li>証明書申請の確認</li>
        <li>証明書申請の処理</li>
        <li>証明書の発行と管理</li>
        </ul>

        <p>自分で認証局を作ることも可能です。
        インターネット環境では危険ですが、
        個人やサーバの身元証明が簡単に行える組織の
        イントラネット内では役に立つかもしれません。</p>
    

    <h4><a name="certificatemanagement" id="certificatemanagement">証明書管理</a></h4>
    
        <p>認証局の開設は徹底した管理、技術、運用の体制を必要とする
        責任のある仕事です。
        認証局は証明書を発行するだけでなく、
        管理もしなければなりません。
        具体的には、証明書がいつまで有効であり続けるかを決定し、更新し、
        また過去発行されて失効した証明書のリスト
        (Certificate Revocation Lists または CRL)
        を管理しなければいけません。</p>
        
        <p>例えばアリスが過去、会社の社員であることを証明する証明書を持っていたが、
        現在は退職していた際、その証明書は失効されなければなりません。
        証明書は次々と人に渡されていくものなので、
        証明書そのものから、それが取り消されたか判断することは
        不可能です。
        よって、証明書の有効性を調べるときには、
        認証局に連絡して CRL を照合する必要があります。
        普通この過程は自動化されているものではありません。</p>

        <div class="note"><h3>注意</h3>
        <p>ブラウザに信用できる認証局としてデフォルトで登録されていない
        認証局を使おうとした場合、
        認証局の証明書をブラウザに読み込んで、
        ブラウザがその認証局によって署名されたサーバの証明書を
        有効にする必要があります。
        一度読み込まれると、その認証局によって署名された全ての
        証明書を受け入れるため、危険を伴います。</p>

<h2><a name="ssl" id="ssl">Secure Sockets Layer (SSL)</a></h2>

<p>Secure Sockets Layer プロトコルは信頼性のあるコネクション型の
ネットワーク層のプロトコル(例えば、TCP/IP)と
アプリケーション層のプロトコル(例えば、HTTP)
の間に置くことができます。
SSL は、相互認証によってサーバとクライアント間の安全な通信を、
電子署名によってデータの完全性を、
そして暗号化によってプライバシを提供します。</p>

<p>SSL プロトコルは暗号化、ダイジェスト、電子署名について、
様々なアルゴリズムをサポートするようにできています。
こうすることで、法や輸出の規制を考慮に入れて、サーバに合わせた
アルゴリズムを選ぶことができ、また、新しいアルゴリズムを
利用していくことも可能にしています。
アルゴリズムの選択はプロトコルセッション開始時に
サーバとクライアント間で取り決められます。</p>

<p><a href="#table4">表4</a>に示されるとおり、SSL プロトコルには
いくつものバージョンがあります。
表にも書かれているように、SSL 3.0 の利点の一つは
証明書階層構造をサポートすることです。
この機能によって、サーバは自分の証明書に加えて、
発行者の証明書をブラウザに渡すことができます。
証明書階層構造によって、
ブラウザに発行者の証明書が直接登録されていなくても、
階層の中に含まれていれば、
ブラウザはサーバの証明書を有効化することができます。
SSL 3.0 は現在 Internet Engineering Task Force (IETF) 
によって開発されている Transport Layer Security 
[<a href="#TLS1">TLS</a>] プロトコル標準規格の基礎となっています。</p>

<h3><a name="session" id="session">セッションの確立</a></h3>

    <p><a href="#figure1">図1</a>で示されるように、
    セッションの確立はクライアントとサーバ間の
    ハンドシェークシークエンスによって行なわれます。
    サーバが証明書を提供するか、クライアントの証明書をリクエストするか
    というサーバの設定により、このシークエンスは異なるものとなります。
    暗号情報の管理のために、追加のハンドシェーク過程が必要になる
    場合もありますが、この記事では
    よくあるシナリオを手短に説明します。
    全ての可能性についは、SSL 仕様書を参照してください。</p>

    <div class="note"><h3>注意</h3>
    <p>一度 SSL セッションが確立すると、セッションを再利用することで、
    セッションを開始するための多くの過程を繰り返すという
    パフォーマンスの損失を防ぎます。
    そのため、サーバは全てのセッションに一意なセッション識別名を
    割り当て、サーバにキャッシュし、クライアントは次回から
    (識別名がサーバのキャッシュで期限切れになるまでは)
    ハンドシェークなしで接続することができます。</p>
    </div>

    <a id="figure1" name="figure1"><dfn>図1</dfn></a>: SSL
    ハンドシェークシークエンス概略</p>

    <p>サーバとクライアントで使われる
    ハンドシェークシークエンスの要素を以下に示します:</p>

    <ol>
    <li>データ通信に使われる暗号スイートの取り決め</li>
    <li>クライアントとサーバ間でのセッション鍵の確立と共有</li>
    <li>オプションとして、クライアントに対するサーバの認証</li>
    <li>オプションとして、サーバに対するクライアントの認証</li>
    </ol>

    <p>第一ステップの暗号スイート取り決めによって、
    サーバとクライアントはそれぞれにあった
    暗号スイートを選ぶことができます。
    SSL3.0 プロトコルの仕様書は 31 の暗号スイートを定義しています。
    暗号スイートは以下のコンポーネントにより定義されています:</p>

    <ul>
    <li>鍵の交換手段</li>
    <li>データ通信の暗号術</li>
    <li>Message Authentication Code (MAC) 作成のための
    メッセージダイジェスト</li>
    </ul>

    <p>これらの三つの要素は以下のセクションで説明されています。</p>


<h3><a name="keyexchange" id="keyexchange">鍵の交換手段</a></h3>

    <p>鍵の交換手段はアプリケーションのデータ通信に使われ、
    共有される対称暗号鍵をどのようにがクライアントとサーバで
    取り決めるかを定義します。
    SSL 2.0 は RSA 鍵交換しか使いませんが、
    SSL 3.0 は (証明書が使われるときの) RSA 鍵交換や、
    (証明書無しの場合やクライアントとサーバの事前の通信が無い場合の)
    Diffie-Hellman 鍵交換
    など様々な鍵交換アルゴリズムをサポートします。</p>

    <p>鍵の交換方法における一つの選択肢は電子署名です。
    電子署名を使うかどうか、また、
    どの種類の署名を使うかという選択があります。
    秘密鍵で署名することで共有鍵を保護し、情報交換する時の
    マン・イン・ザ・ミドル攻撃を防ぐことができます。
    [<a href="#AC96">AC96</a>, p516]</p>


<h3><a name="ciphertransfer" id="ciphertransfer">データ通信の暗号術</a></h3>

    <p>SSL はセッションのメッセージの暗号化に前述した
    対称暗号方式を用います。
    暗号化しないという選択肢も含め九つの暗号方式の選択肢があります:</p>

    <ul>
    <li>暗号化なし</li>
    <li>ストリーム暗号
        <ul>
        <li>40-bit 鍵での RC4</li>
        <li>128-bit 鍵での RC4</li>
        </ul></li>
    <li>CBC ブロック暗号
        <ul><li>40 bit 鍵での RC2</li>
        <li>40 bit 鍵での DES</li>
        <li>56 bit 鍵での DES</li>
        <li>168 bit 鍵での Triple-DES</li>
        <li>Idea (128 bit 鍵)</li>
        <li>Fortezza (96 bit 鍵)</li>
        </ul></li>
    </ul>

    <p>CBC とは暗号ブロック連鎖 (Cipher Block Chaining)
     の略で、一つ前の暗号化された暗号文の一部が
    ブロックの暗号化に使われることを意味します。
    DES はデータ暗号化標準規格 (Data Encryption Standard)
     [<a href="#AC96">AC96</a>, ch12] の略で、
    DES40 や 3DES_EDE を含むいくつもの種類があります。
    Idea は現在最高なものの一つで、暗号術的には現在ある中で
    最も強力なものです。
    RC2 は RSA DSI による独占的なアルゴリズムです。
     [<a href="#AC96">AC96</a>,
    ch13]</p>


<h3><a name="digestfuntion" id="digestfuntion">ダイジェスト関数</a></h3>

    <p>
    ダイジェスト関数の選択はレコードユニットからどのようにダイジェストが生成されるかを決定します。
    SSL は以下をサポートします:</p>

    <ul>
    <li>ダイジェストなし</li>
    <li>MD5 (128-bit ハッシュ)</li>
    <li>Secure Hash Algorithm (SHA-1) (160-bit ハッシュ)</li>
    </ul>

    <p>メッセージダイジェストは Message Authentication Code (MAC) 
    の生成に使われ、メッセージと共に暗号化され、メッセージの信憑性を
    確認し、リプレイ攻撃を防ぎます。</p>


<h3><a name="handshake" id="handshake">ハンドシェークシークエンスプロトコル</a></h3>

    <p>ハンドシェークシークエンスは三つのプロトコルを使います:</p>

    <ul>
    <li><dfn>SSL ハンドシェークプロトコル</dfn>は
    クライアントとサーバ間での SSL セッションの確立に使われます。</li>
    <li><dfn>SSL 暗号仕様変更プロトコル</dfn>は
    セッションでの暗号スイートの取り決めに使われます。</li>
    <li><dfn>SSL 警告プロトコル</dfn>は
    クライアントサーバ間で SSL エラーを伝達するのに使われます。</li>
    </ul>

    <p>三つのプロトコルは、アプリケーションプロトコルデータとともに、
    <a href="#figure2">図2</a>に示すとおり <dfn>SSL レコードプロトコル</dfn>
    でカプセル化されます。
    カプセル化されたプロトコルはデータを検査しない
    下層のプロトコルによってデータとして伝達されます。
    カプセル化されたプロトコルは下層のプロトコルに関して一切関知しません。</p>

    <p class="figure">
    <img src="../images/ssl_intro_fig2.gif" alt="" width="428" height="217" /><br />
    <a id="figure2" name="figure2"><dfn>図2</dfn></a>: SSL プロトコルスタック
    </p>

    <p>
    レコードプロトコルで SSL コントロールプロトコルがカプセル化されているということは、
    アクティブなセッション上で再ネゴシエーションされたときにも、
    コントロールプロトコルは安全であることを意味します。
    既存のセッションが無い場合は、Null 暗号スイートが使われ、
    暗号化は行なわれず、セッションが確立するまでは
    ダイジェストも無い状態となります。</p>


<h3><a name="datatransfer" id="datatransfer">データ通信</a></h3>

    <p><a href="#figure3">図3</a>に示される SSL レコードプロトコル
    はクライアントとサーバ間のアプリケーションや
    SSL コントロールデータの通信に使われます。
    必要に応じてこのデータはより小さいユニットに分けられたり、
    いくつかの高級プロトコルをまとめて一ユニットとして通信が
    行なわれることもあります。
    データを圧縮し、ダイジェスト署名を添付して、
    これらのユニットを暗号化したのち、ベースとなっている
    信頼性のあるトランスポートプロトコルを用いるかもしれません。
    (注意: 現在メジャーな SLL 実装で圧縮をサポートしているものはありません)</p>

    <p class="figure">

    <a id="figure3" name="figure3"><dfn>図 3</dfn></a>: SSL レコードプロトコル
    </p>


<h3><a name="securehttp" id="securehttp">HTTP 通信の安全化</a></h3>

    <p>よくある SSL の使い方はブラウザとウェブサーバ間の HTTP 通信
    の安全化です。
    これは、従来の安全ではない HTTP の使用を除外するものではありません。
    安全化されたもの (HTTPS と呼ばれます) は、SSL 上での普通の HTTP で、
    URL スキームに <code>http</code> の代わりに <code>https</code>
    を用い、サーバで別のポートを使うことです (デフォルトでは443)。
    これが主に <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> が Apache 
    ウェブサーバに提供する機能です。</p>

<p>As an introduction this chapter is aimed at readers who are familiar
with the Web, HTTP, and Apache, but are not security experts. It is not
intended to be a definitive guide to the SSL protocol, nor does it discuss
specific techniques for managing certificates in an organization, or the
important legal issues of patents and import and export restrictions.
Rather, it is intended to provide a common background to <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> users by pulling together various concepts, definitions,
and examples as a starting point for further exploration.</p>

<h2><a name="cryptographictech" id="cryptographictech">Cryptographic Techniques</a></h2>

<p>Understanding SSL requires an understanding of cryptographic
algorithms, message digest functions (aka. one-way or hash functions), and
digital signatures. These techniques are the subject of entire books (see
for instance [<a href="#AC96">AC96</a>]) and provide the basis for privacy,
integrity, and authentication.</p>

<h3><a name="cryptographicalgo" id="cryptographicalgo">Cryptographic Algorithms</a></h3>

    <p>Suppose Alice wants to send a message to her bank to transfer some
    money. Alice would like the message to be private, since it will
    include information such as her account number and transfer amount. One
    solution is to use a cryptographic algorithm, a technique that would
    transform her message into an encrypted form, unreadable until it is
    decrypted. Once in this form, the message can only be
    decrypted by using a secret key. Without the key the message is useless:
    good cryptographic algorithms make it so difficult
    for intruders to decode the original text that it isn't worth their
    effort.</p>

    <p>There are two categories of cryptographic algorithms: conventional
    and public key.</p>

    <dl>
    <dt>Conventional cryptography</dt>
    <dd>also known as symmetric cryptography, requires the sender and
    receiver to share a key: a secret piece of information that may be
    used to encrypt or decrypt a message. As long as this key is kept
    secret, nobody other than the sender or recipient can read the message.
    If Alice and the bank know a secret key, then they can send each other
    private messages. The task of sharing a key between sender and recipient
    before communicating, while also keeping it secret from others, can be
    problematic.</dd>

    <dt>Public key cryptography</dt>
    <dd>also known as asymmetric cryptography, solves the key exchange
    problem by defining an algorithm which uses two keys, each of which
    may be used to encrypt a message. If one key is used to encrypt a
    message then the other must be used to decrypt it. This makes it
    possible to receive secure messages by simply publishing one key
    (the public key) and keeping the other secret (the private key).</dd>
    </dl>

    <p>Anyone can encrypt a message using the public key, but only the
    owner of the private key will be able to read it. In this way, Alice
    can send private messages to the owner of a key-pair (the bank), by
    encrypting them using their public key. Only the bank will be able to
    decrypt them.</p>


<h3><a name="messagedigests" id="messagedigests">Message Digests</a></h3>

    <p>Although Alice may encrypt her message to make it private, there
    is still a concern that someone might modify her original message or
    substitute it with a different one, in order to transfer the money
    to themselves, for instance. One way of guaranteeing the integrity
    of Alice's message is for her to create a concise summary of her
    message and send this to the bank as well. Upon receipt of the message,
    the bank creates its own summary and compares it with the one Alice
    sent. If the summaries are the same then the message has been received
    intact.</p>

    <p>A summary such as this is called a <dfn>message digest</dfn>, <em>one-way
    function</em> or <em>hash function</em>. Message digests are used to create
    a short, fixed-length representation of a longer, variable-length message.
    Digest algorithms are designed to produce a unique digest for each
    message. Message digests are designed to make it impractically difficult
    to determine the message from the digest and (in theory) impossible to
    find two different messages which create the same digest -- thus
    eliminating the possibility of substituting one message for another while
    maintaining the same digest.</p>

    <p>Another challenge that Alice faces is finding a way to send the digest
    to the bank securely; if the digest is not sent securely, its integrity may
    be compromised and with it the possibility for the bank to determine the
    integrity of the original message. Only if the digest is sent securely can
    the integrity of the associated message be determined.</p>

    <p>One way to send the digest securely is to include it in a digital
    signature.</p>


<h3><a name="digitalsignatures" id="digitalsignatures">Digital Signatures</a></h3>
<p>When Alice sends a message to the bank, the bank needs to ensure that the
message is really from her, so an intruder cannot request a transaction
involving her account. A <em>digital signature</em>, created by Alice and
included with the message, serves this purpose.</p>

<p>Digital signatures are created by encrypting a digest of the message and
other information (such as a sequence number) with the sender's private key.
Though anyone can <em>decrypt</em> the signature using the public key, only the
sender knows the private key. This means that only the sender can have signed
the message. Including the digest in the signature means the signature is only
good for that message; it also ensures the integrity of the message since no one
can change the digest and still sign it.</p>
<p>To guard against interception and reuse of the signature by an intruder at a
later date, the signature contains a unique sequence number. This protects
the bank from a fraudulent claim from Alice that she did not send the message
-- only she could have signed it (non-repudiation).</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="certificates" id="certificates">Certificates</a></h2>

<p>Although Alice could have sent a private message to the bank, signed
it and ensured the integrity of the message, she still needs to be sure
that she is really communicating with the bank. This means that she needs
to be sure that the public key she is using is part of the bank's key-pair,
and not an intruder's. Similarly, the bank needs to verify that the message
signature really was signed by the private key that belongs to Alice.</p>

<p>If each party has a certificate which validates the other's identity,
confirms the public key and is signed by a trusted agency, then both
can be assured that they are communicating with whom they think they are.
Such a trusted agency is called a <em>Certificate Authority</em> and
certificates are used for authentication.</p>

<h3><a name="certificatecontents" id="certificatecontents">Certificate Contents</a></h3>

    <p>A certificate associates a public key with the real identity of
    an individual, server, or other entity, known as the subject. As
    shown in <a href="#table1">Table 1</a>, information about the subject
    includes identifying information (the distinguished name) and the
    public key. It also includes the identification and signature of the
    Certificate Authority that issued the certificate and the period of
    time during which the certificate is valid. It may have additional
    information (or extensions) as well as administrative information
    for the Certificate Authority's use, such as a serial number.</p>

    <h4><a name="table1" id="table1">Table 1: Certificate Information</a></h4>
    
    <table>
    
    <tr><th>Subject</th>
        <td>Distinguished Name, Public Key</td></tr>
    <tr><th>Issuer</th>
        <td>Distinguished Name, Signature</td></tr>
    <tr><th>Period of Validity</th>
        <td>Not Before Date, Not After Date</td></tr>
    <tr><th>Administrative Information</th>
        <td>Version, Serial Number</td></tr>
    <tr><th>Extended Information</th>
        <td>Basic Constraints, Netscape Flags, etc.</td></tr>
    </table>
    

    <p>A distinguished name is used to provide an identity in a specific
    context -- for instance, an individual might have a personal
    certificate as well as one for their identity as an employee.
    Distinguished names are defined by the X.509 standard [<a href="#X509">X509</a>], which defines the fields, field names and
    abbreviations used to refer to the fields (see <a href="#table2">Table
    2</a>).</p>

    <h4><a name="table2" id="table2">Table 2: Distinguished Name Information</a></h4>
    
    <table class="bordered">
    
    <tr><th>DN Field</th>
        <th>Abbrev.</th>
        <th>Description</th>
        <th>Example</th></tr>
    <tr><td>Common Name</td>
        <td>CN</td>
        <td>Name being certified</td>
        <td>CN=Joe Average</td></tr>
    <tr><td>Organization or Company</td>
        <td>O</td>
        <td>Name is associated with this<br />organization</td>
        <td>O=Snake Oil, Ltd.</td></tr>
    <tr><td>Organizational Unit</td>
        <td>OU</td>
        <td>Name is associated with this <br />organization unit, such
        as a department</td>
        <td>OU=Research Institute</td></tr>
    <tr><td>City/Locality</td>
        <td>L</td>
        <td>Name is located in this City</td>
        <td>L=Snake City</td></tr>
    <tr><td>State/Province</td>
        <td>ST</td>
        <td>Name is located in this State/Province</td>
        <td>ST=Desert</td></tr>
    <tr><td>Country</td>
        <td>C</td>
        <td>Name is located in this Country (ISO code)</td>
        <td>C=XZ</td></tr>
    </table>
    

    <p>A Certificate Authority may define a policy specifying which
    distinguished field names are optional and which are required. It
    may also place requirements upon the field contents, as may users of
    certificates. For example, a Netscape browser requires that the
    Common Name for a certificate representing a server matches a wildcard
    pattern for the domain name of that server, such
    as <code>*.snakeoil.com</code>.</p>

    <p>The binary format of a certificate is defined using the ASN.1
    notation [<a href="#ASN1">ASN1</a>] [<a href="#PKCS">PKCS</a>]. This
    notation defines how to specify the contents and encoding rules
    define how this information is translated into binary form. The binary
    encoding of the certificate is defined using Distinguished Encoding
    Rules (DER), which are based on the more general Basic Encoding Rules
    (BER). For those transmissions which cannot handle binary, the binary
    form may be translated into an ASCII form by using Base64 encoding
    [<a href="#MIME">MIME</a>]. When placed between begin and end delimiter
    lines (as below), this encoded version is called a PEM ("Privacy Enhanced
    Mail") encoded certificate.</p>

<h3><a name="certificateauthorities" id="certificateauthorities">Certificate Authorities</a></h3>

    <p>By verifying the information in a certificate request
    before granting the certificate, the Certificate Authority assures
    itself of the identity of the private key owner of a key-pair.
    For instance, if Alice requests a personal certificate, the
    Certificate Authority must first make sure that Alice really is the
    person the certificate request claims she is.</p>

    <h4><a name="certificatechains" id="certificatechains">Certificate Chains</a></h4>
    
        <p>A Certificate Authority may also issue a certificate for
        another Certificate Authority. When examining a certificate,
        Alice may need to examine the certificate of the issuer, for each
        parent Certificate Authority, until reaching one which she has
        confidence in. She may decide to trust only certificates with a
        limited chain of issuers, to reduce her risk of a "bad" certificate
        in the chain.</p>
    

    <h4><a name="rootlevelca" id="rootlevelca">Creating a Root-Level CA</a></h4>
    
        <p>As noted earlier, each certificate requires an issuer to assert
        the validity of the identity of the certificate subject, up to
        the top-level Certificate Authority (CA). This presents a problem:
        who can vouch for the certificate of the top-level
        authority, which has no issuer? In this unique case, the
        certificate is "self-signed", so the issuer of the certificate is
        the same as the subject. Browsers are preconfigured to trust well-known
        certificate authorities, but it is important to exercise extra care in
        trusting a self-signed certificate. The wide publication of a
        public key by the root authority reduces the risk in trusting this
        key -- it would be obvious if someone else publicized a key
        claiming to be the authority.</p>

        <p>A number of companies, such as <a href="http://www.thawte.com/">Thawte</a> and <a href="http://www.verisign.com/">VeriSign</a>
        have established themselves as Certificate Authorities. These
        companies provide the following services:</p>

        <ul>
        <li>Verifying certificate requests</li>
        <li>Processing certificate requests</li>
        <li>Issuing and managing certificates</li>
        </ul>

        <p>It is also possible to create your own Certificate Authority.
        Although risky in the Internet environment, it may be useful
        within an Intranet where the organization can easily verify the
        identities of individuals and servers.</p>
    

    <h4><a name="certificatemanagement" id="certificatemanagement">Certificate Management</a></h4>
    
        <p>Establishing a Certificate Authority is a responsibility which
        requires a solid administrative, technical and management
        framework. Certificate Authorities not only issue certificates,
        they also manage them -- that is, they determine for how long
        certificates remain valid, they renew them and keep lists of
        certificates that were issued in the past but are no longer valid
        (Certificate Revocation Lists, or CRLs).</p>

        <p>For example, if Alice is entitled to a certificate as an
        employee of a company but has now left
        that company, her certificate may need to be revoked.
        Because certificates are only issued after the subject's identity has
        been verified and can then be passed around to all those with whom
        the subject may communicate, it is impossible to tell from the
        certificate alone that it has been revoked.
        Therefore when examining certificates for validity
        it is necessary to contact the issuing Certificate Authority to
        check CRLs -- this is usually not an automated part of the process.</p>

        <div class="note"><h3>Note</h3>
        <p>If you use a Certificate Authority that browsers are not configured
        to trust by default, it is necessary to load the Certificate
        Authority certificate into the browser, enabling the browser to
        validate server certificates signed by that Certificate Authority.
        Doing so may be dangerous, since once loaded, the browser will
        accept all certificates signed by that Certificate Authority.</p>

<h2><a name="ssl" id="ssl">Secure Sockets Layer (SSL)</a></h2>

<p>The Secure Sockets Layer protocol is a protocol layer which may be
placed between a reliable connection-oriented network layer protocol
(e.g. TCP/IP) and the application protocol layer (e.g. HTTP). SSL provides
for secure communication between client and server by allowing mutual
authentication, the use of digital signatures for integrity and encryption
for privacy.</p>

<p>The protocol is designed to support a range of choices for specific
algorithms used for cryptography, digests and signatures. This allows
algorithm selection for specific servers to be made based on legal, export
or other concerns and also enables the protocol to take advantage of new
algorithms. Choices are negotiated between client and server when
establishing a protocol session.</p>

<p>There are a number of versions of the SSL protocol, as shown in
<a href="#table4">Table 4</a>. As noted there, one of the benefits in
SSL 3.0 is that it adds support of certificate chain loading. This feature
allows a server to pass a server certificate along with issuer certificates
to the browser. Chain loading also permits the browser to validate the
server certificate, even if Certificate Authority certificates are not
installed for the intermediate issuers, since they are included in the
certificate chain. SSL 3.0 is the basis for the Transport Layer Security
[<a href="#TLS1">TLS</a>] protocol standard, currently in development by
the Internet Engineering Task Force (IETF).</p>

<h3><a name="session" id="session">Establishing a Session</a></h3>

    <p>The SSL session is established by following a handshake sequence
    between client and server, as shown in <a href="#figure1">Figure 1</a>. This sequence may vary, depending on whether the server
    is configured to provide a server certificate or request a client
    certificate. Although cases exist where additional handshake steps
    are required for management of cipher information, this article
    summarizes one common scenario. See the SSL specification for the full
    range of possibilities.</p>

    <div class="note"><h3>Note</h3>
    <p>Once an SSL session has been established, it may be reused. This
    avoids the performance penalty of repeating the many steps needed
    to start a session. To do this, the server assigns each SSL session a
    unique session identifier which is cached in the server and which the
    client can use in future connections to reduce the handshake time
    (until the session identifier expires from the cache of the server).</p>
    </div>

    <p class="figure">
    <img src="../images/ssl_intro_fig1.gif" alt="" width="423" height="327" /><br />
    <a id="figure1" name="figure1"><dfn>Figure 1</dfn></a>: Simplified SSL
    Handshake Sequence</p>

    <p>The elements of the handshake sequence, as used by the client and
    server, are listed below:</p>

    <ol>
    <li>Negotiate the Cipher Suite to be used during data transfer</li>
    <li>Establish and share a session key between client and server</li>
    <li>Optionally authenticate the server to the client</li>
    <li>Optionally authenticate the client to the server</li>
    </ol>

    <p>The first step, Cipher Suite Negotiation, allows the client and
    server to choose a Cipher Suite supported by both of them. The SSL3.0
    protocol specification defines 31 Cipher Suites. A Cipher Suite is
    defined by the following components:</p>

    <ul>
    <li>Key Exchange Method</li>
    <li>Cipher for Data Transfer</li>
    <li>Message Digest for creating the Message Authentication Code (MAC)</li>
    </ul>

    <p>These three elements are described in the sections that follow.</p>


<h3><a name="keyexchange" id="keyexchange">Key Exchange Method</a></h3>

    <p>The key exchange method defines how the shared secret symmetric
    cryptography key used for application data transfer will be agreed
    upon by client and server. SSL 2.0 uses RSA key exchange only, while
    SSL 3.0 supports a choice of key exchange algorithms including
    RSA key exchange (when certificates are used), and Diffie-Hellman key
    exchange (for exchanging keys without certificates, or without prior
    communication between client and server).</p>

    <p>One variable in the choice of key exchange methods is digital
    signatures -- whether or not to use them, and if so, what kind of
    signatures to use. Signing with a private key provides protection
    against a man-in-the-middle-attack during the information exchange
    used to generating the shared key [<a href="#AC96">AC96</a>, p516].</p>


<h3><a name="ciphertransfer" id="ciphertransfer">Cipher for Data Transfer</a></h3>

    <p>SSL uses conventional symmetric cryptography, as described earlier,
    for encrypting messages in a session.
    There are nine choices of how to encrypt, including the option not to
    encrypt:</p>

    <ul>
    <li>No encryption</li>
    <li>Stream Ciphers
        <ul>
        <li>RC4 with 40-bit keys</li>
        <li>RC4 with 128-bit keys</li>
        </ul></li>
    <li>CBC Block Ciphers
        <ul><li>RC2 with 40 bit key</li>
        <li>DES with 40 bit key</li>
        <li>DES with 56 bit key</li>
        <li>Triple-DES with 168 bit key</li>
        <li>Idea (128 bit key)</li>
        <li>Fortezza (96 bit key)</li>
        </ul></li>
    </ul>

    <p>"CBC" refers to Cipher Block Chaining, which means that a
    portion of the previously encrypted cipher text is used in the
    encryption of the current block. "DES" refers to the Data Encryption
    Standard [<a href="#AC96">AC96</a>, ch12], which has a number of
    variants (including DES40 and 3DES_EDE). "Idea" is currently one of
    the best and cryptographically strongest algorithms available,
    and "RC2" is a proprietary algorithm from RSA DSI [<a href="#AC96">AC96</a>, ch13].</p>


<h3><a name="digestfunction" id="digestfunction">Digest Function</a></h3>

    <p>The choice of digest function determines how a digest is created
    from a record unit. SSL supports the following:</p>

    <ul>
    <li>No digest (Null choice)</li>
    <li>MD5, a 128-bit hash</li>
    <li>Secure Hash Algorithm (SHA-1), a 160-bit hash</li>
    </ul>

    <p>The message digest is used to create a Message Authentication Code
    (MAC) which is encrypted with the message to verify integrity and to
    protect against replay attacks.</p>


<h3><a name="handshake" id="handshake">Handshake Sequence Protocol</a></h3>

    <p>The handshake sequence uses three protocols:</p>

    <ul>
    <li>The <dfn>SSL Handshake Protocol</dfn>
    for performing the client and server SSL session establishment.</li>
    <li>The <dfn>SSL Change Cipher Spec Protocol</dfn> for actually
    establishing agreement on the Cipher Suite for the session.</li>
    <li>The <dfn>SSL Alert Protocol</dfn> for conveying SSL error
    messages between client and server.</li>
    </ul>

    <p>These protocols, as well as application protocol data, are
    encapsulated in the <dfn>SSL Record Protocol</dfn>, as shown in
    <a href="#figure2">Figure 2</a>. An encapsulated protocol is
    transferred as data by the lower layer protocol, which does not
    examine the data. The encapsulated protocol has no knowledge of the
    underlying protocol.</p>

    <p class="figure">
    <img src="../images/ssl_intro_fig2.gif" alt="" width="428" height="217" /><br />
    <a id="figure2" name="figure2"><dfn>Figure 2</dfn></a>: SSL Protocol Stack
    </p>

    <p>The encapsulation of SSL control protocols by the record protocol
    means that if an active session is renegotiated the control protocols
    will be transmitted securely. If there was no previous session,
    the Null cipher suite is used, which means there will be no encryption and
    messages will have no integrity digests, until the session has been
    established.</p>


<h3><a name="datatransfer" id="datatransfer">Data Transfer</a></h3>

    <p>The SSL Record Protocol, shown in <a href="#figure3">Figure 3</a>,
    is used to transfer application and SSL Control data between the
    client and server, where necessary fragmenting this data into smaller units,
    or combining multiple higher level protocol data messages into single
    units. It may compress, attach digest signatures, and encrypt these
    units before transmitting them using the underlying reliable transport
    protocol (Note: currently, no major SSL implementations include support
    for compression).</p>

    <p class="figure">
    <img src="../images/ssl_intro_fig3.gif" alt="" width="423" height="323" /><br />
    <a id="figure3" name="figure3"><dfn>Figure 3</dfn></a>: SSL Record Protocol
    </p>


<h3><a name="securehttp" id="securehttp">Securing HTTP Communication</a></h3>

    <p>One common use of SSL is to secure Web HTTP communication between
    a browser and a webserver. This does not preclude the use of
    non-secured HTTP - the secure version (called HTTPS) is the same as
    plain HTTP over SSL, but uses the URL scheme <code>https</code>
    rather than <code>http</code>, and a different server port (by default,
    port 443). This functionality is a large part of what <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> provides for the Apache webserver.</p>

        <dt>Description:</dt>

        <dd>
          <p>The following technique forbids the practice of other sites
          including your images inline in their pages. This practice is
          often referred to as "hotlinking", and results in
          your bandwidth being used to serve content for someone else's
          site.</p>
        </dd>

        <dt>Solution:</dt>

        <dd>
          <p>This technique relies on the value of the
          <code>HTTP_REFERER</code> variable, which is optional. As
          such, it's possible for some people to circumvent this
          limitation. However, most users will experience the failed
          request, which should, over time, result in the image being
          removed from that other site.</p>
          <p>There are several ways that you can handle this
          situation.</p>

    <p>In this first example, we simply deny the request, if it didn't
    initiate from a page on our site. For the purpose of this example,
    we assume that our site is <code>www.example.com</code>.</p>



<pre class="prettyprint lang-config">RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule "\.(gif|jpg|png)$"    "-"   [F,NC]</pre>


    <p>In this second example, instead of failing the request, we display
    an alternate image instead.</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule "\.(gif|jpg|png)$"    "/images/go-away.png"   [R,NC]</pre>


    <p>In the third example, we redirect the request to an image on some
    other site.</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule "\.(gif|jpg|png)$" "http://other.example.com/image.gif"   [R,NC]</pre>


    <p>Of these techniques, the last two tend to be the most effective
    in getting people to stop hotlinking your images, because they will
    simply not see the image that they expected to see.</p>

        </dd>

        <dt>Discussion:</dt>

        <dd>
        <p>If all you wish to do is deny access to the resource, rather
        than redirecting that request elsewhere, this can be
        accomplished without the use of mod_rewrite:</p>

        <pre class="prettyprint lang-config">SetEnvIf Referer "example\.com" localreferer
&lt;FilesMatch "\.(jpg|png|gif)$"&gt;
    Require env localreferer
&lt;/FilesMatch&gt;</pre>

        </dd>
      </dl>

        <dt>Description:</dt>

        <dd>
        <p>
        In this recipe, we discuss how to block persistent requests from
        a particular robot, or user agent.</p>

        <p>The standard for robot exclusion defines a file,
        <code>/robots.txt</code> that specifies those portions of your
        website where you wish to exclude robots. However, some robots
        do not honor these files.
        </p>

        <p>Note that there are methods of accomplishing this which do
        not use mod_rewrite. Note also that any technique that relies on
        the clients <code>USER_AGENT</code> string can be circumvented
        very easily, since that string can be changed.</p>
        </dd>

        <dt>Solution:</dt>

        <dd>
        <p>We use a ruleset that specifies the directory to be
        protected, and the client <code>USER_AGENT</code> that
        identifies the malicious or persistent robot.</p>

        <p>In this example, we are blocking a robot called
        <code>NameOfBadRobot</code> from a location
        <code>/secret/files</code>. You may also specify an IP address
        range, if you are trying to block that user agent only from the
        particular source.</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_USER_AGENT}"   "^NameOfBadRobot"
RewriteCond "%{REMOTE_ADDR}"       "=123\.45\.67\.[8-9]"
RewriteRule "^/secret/files/"   "-"   [F]</pre>

        </dd>

      <dt>Discussion:</dt>

      <dd>
      <p>
        Rather than using mod_rewrite for this, you can accomplish the
        same end using alternate means, as illustrated here:
      </p>
      <pre class="prettyprint lang-config">SetEnvIfNoCase User-Agent "^NameOfBadRobot" goaway
&lt;Location "/secret/files"&gt;
    &lt;RequireAll&gt;
        Require all granted
        Require not env goaway
    &lt;/RequireAll&gt;
&lt;/Location&gt;</pre>

      <p>
      As noted above, this technique is trivial to circumvent, by simply
      modifying the <code>USER_AGENT</code> request header. If you
      are experiencing a sustained attack, you should consider blocking
      it at a higher level, such as at your firewall.

    <p>
    The second RewriteCond assumes that you have HostNameLookups turned
    on, so that client IP addresses will be resolved. If that's not the
    case, you should drop the second RewriteCond, and drop the
    <code>[OR]</code> flag from the first RewriteCond.

      <p>The map file lists redirection targets for each referer, or, if

<p>This document supplements the <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>
<a href="../mod/mod_rewrite.html">reference documentation</a>. It describes
perhaps one of the most important concepts about <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> - namely,
when to avoid using it.</p>

<p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> should be considered a last resort, when other
alternatives are found wanting. Using it when there are simpler
alternatives leads to configurations which are confusing, fragile, and
hard to maintain. Understanding what other alternatives are available is
a very important step towards <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> mastery.</p>

<p>Note that many of these examples won't work unchanged in your
particular server configuration, so it's important that you understand
them, rather than merely cutting and pasting the examples into your
configuration.</p>

<p>The most common situation in which <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> is
the right tool is when the very best solution requires access to the
server configuration files, and you don't have that access. Some
configuration directives are only available in the server configuration
file. So if you are in a hosting situation where you only have .htaccess
files to work with, you may need to resort to
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>.</p>

<h2><a name="redirect" id="redirect">Simple Redirection</a></h2>


<p><code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> provides the <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code> and <code class="directive"><a href="../mod/mod_alias.html#redirectmatch">RedirectMatch</a></code> directives, which provide a
means to redirect one URL to another. This kind of simple redirection of
one URL, or a class of URLs, to somewhere else, should be accomplished
using these directives rather than <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>. <code>RedirectMatch</code>
allows you to include a regular expression in your redirection criteria,
providing many of the benefits of using <code>RewriteRule</code>.</p>

<p>A common use for <code>RewriteRule</code> is to redirect an entire
class of URLs. For example, all URLs in the <code>/one</code> directory
must be redirected to <code>http://one.example.com/</code>, or perhaps
all <code>http</code> requests must be redirected to
<code>https</code>.</p>

<p>These situations are better handled by the <code>Redirect</code>
directive. Remember that <code>Redirect</code> preserves path
information. That is to say, a redirect for a URL <code>/one</code> will
also redirect all URLs under that, such as <code>/one/two.html</code>
and <code>/one/three/four.html</code>.</p>

<p>To redirect URLs under <code>/one</code> to
<code>http://one.example.com</code>, do the following:</p>

<pre class="prettyprint lang-config">Redirect "/one/" "http://one.example.com/"</pre>


<p>To redirect one hostname to another, for example
<code>example.com</code> to <code>www.example.com</code>, see the
<a href="remapping.html#canonicalhost">Canonical Hostnames</a>
recipe.</p>

<p>To redirect <code>http</code> URLs to <code>https</code>, do the
following:</p>

<pre class="prettyprint lang-config">&lt;VirtualHost *:80&gt;
    ServerName www.example.com
    Redirect "/" "https://www.example.com/"
&lt;/VirtualHost&gt;

&lt;VirtualHost *:443&gt;
    ServerName www.example.com
    # ... SSL configuration goes here
&lt;/VirtualHost&gt;</pre>


<p>The use of <code>RewriteRule</code> to perform this task may be
appropriate if there are other <code>RewriteRule</code> directives in
the same scope. This is because, when there are <code>Redirect</code>
and <code>RewriteRule</code> directives in the same scope, the
<code>RewriteRule</code> directives will run first, regardless of the
order of appearance in the configuration file.</p>

<p>In the case of the <em>http-to-https</em> redirection, the use of
<code>RewriteRule</code> would be appropriate if you don't have access
to the main server configuration file, and are obliged to perform this
task in a <code>.htaccess</code> file instead.</p>

<h2><a name="alias" id="alias">URL Aliasing</a></h2>
<p>The <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> directive
provides mapping from a URI to a directory - usually a directory outside
of your <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>. Although it
is possible to perform this mapping with <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>,

The use of <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> to perform this mapping may be
appropriate when you do not have access to the server configuration
files. Alias may only be used in server or virtualhost context, and not
in a <code>.htaccess</code> file.
</p>

<p>Symbolic links would be another way to accomplish the same thing, if
you have <code>Options FollowSymLinks</code> enabled on your
server.</p>

<h2><a name="vhosts" id="vhosts">Virtual Hosting</a></h2>
<p>Although it is possible to handle <a href="vhosts.html">virtual hosts
with mod_rewrite</a>, it is seldom the right way. Creating individual
<code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code> blocks is
almost always the right way to go. In the
event that you have an enormous number of virtual hosts, consider using
<code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code> to create these hosts automatically.</p>

<p>Modules such as <code class="module"><a href="../mod/mod_macro.html">mod_macro</a></code> are
also useful for creating a large number of virtual hosts dynamically.</p>

<p>Using <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> for vitualhost creation may be
appropriate if you are using a hosting service that does not provide
you access to the server configuration files, and you are therefore
restricted to configuration using <code>.htaccess</code> files.</p>

<p>See the <a href="vhosts.html">virtual hosts with mod_rewrite</a>
document for more details on how you might accomplish this if it still
seems like the right approach.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="proxy" id="proxy">Simple Proxying</a></h2>

<p><code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> provides the <a href="flags.html#flag_p">[P]</a> flag to pass rewritten URIs through
<code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>.</p>

<pre class="prettyprint lang-config">RewriteRule "^/?images(.*)" "http://imageserver.local/images$1" [P]</pre>


<p>However, in many cases, when there is no actual pattern matching
needed, as in the example shown above, the <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> directive is a better choice.
The example here could be rendered as:</p>

<pre class="prettyprint lang-config">ProxyPass "/images/" "http://imageserver.local/images/"</pre>


<p>Note that whether you use <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> or <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>, you'll still need to use the
<code class="directive"><a href="../mod/mod_proxy.html#proxypassreverse">ProxyPassReverse</a></code> directive to
catch redirects issued from the back-end server:</p>

<pre class="prettyprint lang-config">ProxyPassReverse "/images/" "http://imageserver.local/images/"</pre>


<p>You may need to use <code>RewriteRule</code> instead when there are
other <code>RewriteRule</code>s in effect in the same scope, as a
<code>RewriteRule</code> will usually take effect before a
<code>ProxyPass</code>, and so may preempt what you're trying to
accomplish.</p>

<div class="section">
<h2><a name="setenv" id="setenv">Environment Variable Testing</a></h2>

<p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> is frequently used to take a particular
action based on the presence or absence of a particular environment
variable or request header. This can be done more efficiently using the
<code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code>.</p>

<p>Consider, for example, the common scenario where
<code class="directive">RewriteRule</code> is used to enforce a canonical
hostname, such as <code>www.example.com</code> instead of
<code>example.com</code>. This can be done using the <code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code> directive, as shown here:</p>

<pre class="prettyprint lang-config">&lt;If "req('Host') != 'www.example.com'"&gt;
    Redirect "/" "http://www.example.com/"
&lt;/If&gt;</pre>


<p>This technique can be used to take actions based on any request
header, response header, or environment variable, replacing
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> in many common scenarios.</p>

<p>See especially the <a href="../expr.html">expression evaluation
documentation</a> for a overview of what types of expressions you can
use in <code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code> sections,
and in certain other directives.</p>

<h2><a name="introduction" id="introduction">Introduction</a></h2>
<p>A <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> can have
its behavior modified by one or more flags. Flags are included in
square brackets at the end of the rule, and multiple flags are separated
by commas.</p>
<pre class="prettyprint lang-config">RewriteRule pattern target [Flag1,Flag2,Flag3]</pre>


<p>Each flag (with a few exceptions) has a short form, such as
<code>CO</code>, as well as a longer form, such as <code>cookie</code>. 
While it is most common to use
the short form, it is recommended that you familiarize yourself with the
long form, so that you remember what each flag is supposed to do.
Some flags take one or more arguments. Flags are not case sensitive.</p>

<p>Flags that alter metadata associated with the request (T=, H=, E=)
have no affect in per-directory and htaccess context, when a substitution
(other than '-') is performed during the same round of rewrite processing.
</p>

<p>Presented here are each of the available flags, along with an example
of how you might use them.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_b" id="flag_b">B (escape backreferences)</a></h2>
<p>The [B] flag instructs <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> to escape non-alphanumeric
characters before applying the transformation.</p>
<p>In 2.4.26 and later, you can limit the escaping to specific characters
in backreferences by listing them: <code>[B=#?;]</code>. Note: The space
character can be used in the list of characters to escape, but it cannot be
the last character in the list.</p>

<p><code>mod_rewrite</code> has to unescape URLs before mapping them,
so backreferences are unescaped at the time they are applied.
Using the B flag, non-alphanumeric characters in backreferences
will be escaped. For example, consider the rule:</p>

<pre class="prettyprint lang-config">RewriteRule "^search/(.*)$" "/search.php?term=$1"</pre>


<p>Given a search term of 'x &amp; y/z', a browser will encode it as
'x%20%26%20y%2Fz', making the request 'search/x%20%26%20y%2Fz'. Without the B
flag, this rewrite rule will map to 'search.php?term=x &amp; y/z', which
isn't a valid URL, and so would be encoded as
<code>search.php?term=x%20&amp;y%2Fz=</code>, which is not what was intended.</p>

<p>With the B flag set on this same rule, the parameters are re-encoded
before being passed on to the output URL, resulting in a correct mapping to
<code>/search.php?term=x%20%26%20y%2Fz</code>.</p>

<pre class="prettyprint lang-config">RewriteRule "^search/(.*)$" "/search.php?term=$1" [B,PT]</pre>


<p>Note that you may also need to set <code class="directive"><a href="../mod/core.html#allowencodedslashes">AllowEncodedSlashes</a></code> to <code>On</code> to get this
particular example to work, as httpd does not allow encoded slashes in URLs, and
returns a 404 if it sees one.</p>

<p>This escaping is particularly necessary in a proxy situation,
when the backend may break if presented with an unescaped URL.</p>

<p>An alternative to this flag is using a <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> to capture against %{THE_REQUEST} which will capture
strings in the encoded form.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_bnp" id="flag_bnp">BNP|backrefnoplus (don't escape space to +)</a></h2>
<p>The [BNP] flag instructs <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> to escape the space character
in a backreference to %20 rather than '+'. Useful when the backreference
will be used in the path component rather than the query string.</p>

<p>This flag is available in version 2.4.26 and later.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_c" id="flag_c">C|chain</a></h2>
<p>The [C] or [chain] flag indicates that the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> is chained to the next
rule. That is, if the rule matches, then it is processed as usual and
control moves on to the next rule. However, if it does not match, then
the next rule, and any other rules that are chained together, are
skipped.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_co" id="flag_co">CO|cookie</a></h2>
<p>The [CO], or [cookie] flag, allows you to set a cookie when a
particular <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>
matches. The argument consists of three required fields and five optional
fields.</p>

<p>The full syntax for the flag, including all attributes, is as
follows:</p>

<div class="example"><p><code>
[CO=NAME:VALUE:DOMAIN:lifetime:path:secure:httponly:samesite]
</code></p></div>

<p>If a literal ':' character is needed in any of the cookie fields, an 
alternate syntax is available.  To opt-in to the alternate syntax, the cookie 
"Name" should be preceded with a ';' character, and field separators should be
specified as ';'.</p>

<div class="example"><p><code>
[CO=;NAME;VALUE:MOREVALUE;DOMAIN;lifetime;path;secure;httponly;samesite]
</code></p></div>

<p>You must declare a name, a value, and a domain for the cookie to be set.</p>

<dl>
<dt>Domain</dt>
<dd>The domain for which you want the cookie to be valid. This may be a
hostname, such as <code>www.example.com</code>, or it may be a domain,
such as <code>.example.com</code>. It must be at least two parts
separated by a dot. That is, it may not be merely <code>.com</code> or
<code>.net</code>. Cookies of that kind are forbidden by the cookie
security model.</dd>
</dl>

<p>You may optionally also set the following values:</p>

<dl>
<dt>Lifetime</dt>
<dd>The time for which the cookie will persist, in minutes.</dd>
<dd>A value of 0 indicates that the cookie will persist only for the
current browser session. This is the default value if none is
specified.</dd>

<dt>Path</dt>
<dd>The path, on the current website, for which the cookie is valid,
such as <code>/customers/</code> or <code>/files/download/</code>.</dd>
<dd>By default, this is set to <code>/</code> - that is, the entire
website.</dd>

<dt>Secure</dt>
<dd>If set to <code>secure</code>, <code>true</code>, or <code>1</code>,
the cookie will only be permitted to be translated via secure (https)
connections.</dd>

<dt>httponly</dt>
<dd>If set to <code>HttpOnly</code>, <code>true</code>, or
<code>1</code>, the cookie will have the <code>HttpOnly</code> flag set,
which means that the cookie is inaccessible to JavaScript code on
browsers that support this feature.</dd>

<dt>samesite</dt>
<dd>If set to anything other than <code>false</code> or <code>0</code>, the <code>SameSite</code>
attribute is set to the specified value.  Typical values are <code>None</code>,
<code>Lax</code>, and <code>Strict</code>.Available in 2.5.1 and later.</dd>
</dl>


<p>Consider this example:</p>

<pre class="prettyprint lang-config">RewriteEngine On
RewriteRule "^/index\.html" "-" [CO=frontdoor:yes:.example.com:1440:/]</pre>


<p>In the example give, the rule doesn't rewrite the request.
The "-" rewrite target tells mod_rewrite to pass the request
through unchanged. Instead, it sets a cookie
called 'frontdoor' to a value of 'yes'. The cookie is valid for any host
in the <code>.example.com</code> domain. It is set to expire in 1440
minutes (24 hours) and is returned for all URIs.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_dpi" id="flag_dpi">DPI|discardpath</a></h2>
<p>The DPI flag causes the PATH_INFO portion of the rewritten URI to be
discarded.</p>
<p>This flag is available in version 2.2.12 and later.</p>
<p>In per-directory context, the URI each <code class="directive">RewriteRule</code>
compares against is the concatenation of the current values of the URI
and PATH_INFO.</p>

<p>The current URI can be the initial URI as requested by the client, the
result of a previous round of mod_rewrite processing, or the result of
a prior rule in the current round of mod_rewrite processing.</p>

<p>In contrast, the PATH_INFO that is appended to the URI before each
rule reflects only the value of PATH_INFO before this round of
mod_rewrite processing. As a consequence, if large portions
of the URI are matched and copied into a substitution in multiple
<code class="directive">RewriteRule</code> directives, without regard for
which parts of the URI came from the current PATH_INFO, the final
URI may have multiple copies of PATH_INFO appended to it.</p>

<p>Use this flag on any substitution where the PATH_INFO that resulted
from the previous mapping of this request to the filesystem is not of
interest.  This flag permanently forgets the PATH_INFO established
before this round of mod_rewrite processing began. PATH_INFO will
not be recalculated until the current round of mod_rewrite processing
completes.  Subsequent rules during this round of processing will see
only the direct result of substitutions, without any PATH_INFO
appended.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_e" id="flag_e">E|env</a></h2>
<p>With the [E], or [env] flag, you can set the value of an environment
variable. Note that some environment variables may be set after the rule
is run, thus unsetting what you have set. See <a href="../env.html">the
Environment Variables document</a> for more details on how Environment
variables work.</p>

<p>The full syntax for this flag is:</p>

<pre class="prettyprint lang-config">[E=VAR:VAL]
[E=!VAR]</pre>


<p><code>VAL</code> may contain backreferences (<code>$N</code> or
<code>%N</code>) which are expanded.</p>

<p>Using the short form</p>

<div class="example"><p><code>
[E=VAR]
</code></p></div>

<p>you can set the environment variable named <code>VAR</code> to an
empty value.</p>

<p>The form</p>

<div class="example"><p><code>
[E=!VAR]
</code></p></div>

<p>allows to unset a previously set environment variable named
<code>VAR</code>.</p>

<p>Environment variables can then be used in a variety of
contexts, including CGI programs, other RewriteRule directives, or
CustomLog directives.</p>

<p>The following example sets an environment variable called 'image' to a
value of '1' if the requested URI is an image file. Then, that
environment variable is used to exclude those requests from the access
log.</p>

<pre class="prettyprint lang-config">RewriteRule "\.(png|gif|jpg)$" "-" [E=image:1]
CustomLog "logs/access_log" combined env=!image</pre>


<p>Note that this same effect can be obtained using <code class="directive"><a href="../mod/mod_setenvif.html#setenvif">SetEnvIf</a></code>. This technique is offered as
an example, not as a recommendation.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_end" id="flag_end">END</a></h2>
<p>Using the [END] flag terminates not only the current round of rewrite
processing (like [L]) but also prevents any subsequent rewrite
processing from occurring in per-directory (htaccess) context.</p>

<p>This does not apply to new requests resulting from external
redirects.</p>

<div class="section">
<h2><a name="flag_f" id="flag_f">F|forbidden</a></h2>
<p>Using the [F] flag causes the server to return a 403 Forbidden status
code to the client. While the same behavior can be accomplished using
the <code class="directive"><a href="../mod/mod_access_compat.html#deny">Deny</a></code> directive, this
allows more flexibility in assigning a Forbidden status.</p>

<p>The following rule will forbid <code>.exe</code> files from being
downloaded from your server.</p>

<pre class="prettyprint lang-config">RewriteRule "\.exe" "-" [F]</pre>


<p>This example uses the "-" syntax for the rewrite target, which means
that the requested URI is not modified. There's no reason to rewrite to
another URI, if you're going to forbid the request.</p>

<p>When using [F], an [L] is implied - that is, the response is returned
immediately, and no further rules are evaluated.</p>

<div class="section">
<h2><a name="flag_g" id="flag_g">G|gone</a></h2>
<p>The [G] flag forces the server to return a 410 Gone status with the
response. This indicates that a resource used to be available, but is no
longer available.</p>

<p>As with the [F] flag, you will typically use the "-" syntax for the
rewrite target when using the [G] flag:</p>

<pre class="prettyprint lang-config">RewriteRule "oldproduct" "-" [G,NC]</pre>


<p>When using [G], an [L] is implied - that is, the response is returned
immediately, and no further rules are evaluated.</p>

<div class="section">
<h2><a name="flag_h" id="flag_h">H|handler</a></h2>
<p>Forces the resulting request to be handled with the specified
handler. For example, one might use this to force all files without a
file extension to be parsed by the php handler:</p>

<pre class="prettyprint lang-config">RewriteRule "!\." "-" [H=application/x-httpd-php]</pre>


<p>
The regular expression above - <code>!\.</code> - will match any request
that does not contain the literal <code>.</code> character.
</p>

<p>This can be also used to force the handler based on some conditions.
For example, the following snippet used in per-server context allows
<code>.php</code> files to be <em>displayed</em> by <code>mod_php</code>
if they are requested with the <code>.phps</code> extension:</p>

<pre class="prettyprint lang-config">RewriteRule "^(/source/.+\.php)s$" "$1" [H=application/x-httpd-php-source]</pre>


<p>The regular expression above - <code>^(/source/.+\.php)s$</code> - will
match any request that starts with <code>/source/</code> followed by 1 or
n characters followed by <code>.phps</code> literally. The backreference
$1 referrers to the captured match within parenthesis of the regular
expression.</p>

<div class="section">
<h2><a name="flag_l" id="flag_l">L|last</a></h2>
<p>The [L] flag causes <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> to stop processing
the rule set. In most contexts, this means that if the rule matches, no
further rules will be processed. This corresponds to the
<code>last</code> command in Perl, or the <code>break</code> command in
C. Use this flag to indicate that the current rule should be applied
immediately without considering further rules.</p>

<p>If you are using <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> in either
<code>.htaccess</code> files or in
<code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections,
it is important to have some understanding of how the rules are
processed.  The simplified form of this is that once the rules have been
processed, the rewritten request is handed back to the URL parsing
engine to do what it may with it. It is possible that as the rewritten
request is handled, the <code>.htaccess</code> file or
<code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> section
may be encountered again, and thus the ruleset may be run again from the
start. Most commonly this will happen if one of the rules causes a
redirect - either internal or external - causing the request process to
start over.</p>

<p>It is therefore important, if you are using <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> directives in one of these
contexts, that you take explicit steps to avoid rules looping, and not
count solely on the [L] flag to terminate execution of a series of
rules, as shown below.</p>

<p> An alternative flag, [END], can be used to terminate not only the
current round of rewrite processing but prevent any subsequent
rewrite processing from occurring in per-directory (htaccess)
context. This does not apply to new requests resulting from external
redirects.</p>

<p>The example given here will rewrite any request to
<code>index.php</code>, giving the original request as a query string
argument to <code>index.php</code>, however, the <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> ensures that if the request
is already for <code>index.php</code>, the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> will be skipped.</p>

<pre class="prettyprint lang-config">RewriteBase "/"
RewriteCond "%{REQUEST_URI}" "!=/index.php"
RewriteRule "^(.*)" "/index.php?req=$1" [L,PT]</pre>

<div class="section">
<h2><a name="flag_n" id="flag_n">N|next</a></h2>
<p>
The [N] flag causes the ruleset to start over again from the top, using
the result of the ruleset so far as a starting point. Use
with extreme caution, as it may result in loop.
</p>
<p>
The [Next] flag could be used, for example, if you wished to replace a
certain string or letter repeatedly in a request. The example shown here
will replace A with B everywhere in a request, and will continue doing
so until there are no more As to be replaced.
</p>
<pre class="prettyprint lang-config">RewriteRule "(.*)A(.*)" "$1B$2" [N]</pre>

<p>You can think of this as a <code>while</code> loop: While this
pattern still matches (i.e., while the URI still contains an
<code>A</code>), perform this substitution (i.e., replace the
<code>A</code> with a <code>B</code>).</p>

<p>In 2.4.8 and later, this module returns an error after 32,000 iterations to
protect against unintended looping.  An alternative maximum number of 
iterations can be specified by adding to the N flag.  </p>
<pre class="prettyprint lang-config"># Be willing to replace 1 character in each pass of the loop
RewriteRule "(.+)[&gt;&lt;;]$" "$1" [N=64000]
# ... or, give up if after 10 loops
RewriteRule "(.+)[&gt;&lt;;]$" "$1" [N=10]</pre>

<div class="section">
<h2><a name="flag_nc" id="flag_nc">NC|nocase</a></h2>
<p>Use of the [NC] flag causes the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> to be matched in a
case-insensitive manner. That is, it doesn't care whether letters appear
as upper-case or lower-case in the matched URI.</p>

<p>In the example below, any request for an image file will be proxied
to your dedicated image server. The match is case-insensitive, so that
<code>.jpg</code> and <code>.JPG</code> files are both acceptable, for
example.</p>

<pre class="prettyprint lang-config">RewriteRule "(.*\.(jpg|gif|png))$" "http://images.example.com$1" [P,NC]</pre>

<h2><a name="flag_ne" id="flag_ne">NE|noescape</a></h2>
<p>By default, special characters, such as <code>&amp;</code> and
<code>?</code>, for example, will be converted to their hexcode
equivalent. Using the [NE] flag prevents that from happening.
</p>

<pre class="prettyprint lang-config">RewriteRule "^/anchor/(.+)" "/bigpage.html#$1" [NE,R]</pre>


<p>
The above example will redirect <code>/anchor/xyz</code> to
<code>/bigpage.html#xyz</code>. Omitting the [NE] will result in the #
being converted to its hexcode equivalent, <code>%23</code>, which will
then result in a 404 Not Found error condition.

<div class="section">
<h2><a name="flag_ns" id="flag_ns">NS|nosubreq</a></h2>
<p>Use of the [NS] flag prevents the rule from being used on
subrequests. For example, a page which is included using an SSI (Server
Side Include) is a subrequest, and you may want to avoid rewrites
happening on those subrequests. Also, when <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code>
tries to find out information about possible directory default files
(such as <code>index.html</code> files), this is an internal
subrequest, and you often want to avoid rewrites on such subrequests.
On subrequests, it is not always useful, and can even cause errors, if
the complete set of rules are applied. Use this flag to exclude
problematic rules.</p>

<p>To decide whether or not to use this rule: if you prefix URLs with
CGI-scripts, to force them to be processed by the CGI-script, it's
likely that you will run into problems (or significant overhead)
on sub-requests. In these cases, use this flag.</p>

<p>
Images, javascript files, or css files, loaded as part of an HTML page,
are not subrequests - the browser requests them as separate HTTP
requests.

<div class="section">
<h2><a name="flag_p" id="flag_p">P|proxy</a></h2>
<p>Use of the [P] flag causes the request to be handled by
<code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>, and handled via a proxy request. For
example, if you wanted all image requests to be handled by a back-end
image server, you might do something like the following:</p>

<pre class="prettyprint lang-config">RewriteRule "/(.*)\.(jpg|gif|png)$" "http://images.example.com/$1.$2" [P]</pre>


<p>Use of the [P] flag implies [L] - that is, the request is immediately
pushed through the proxy, and any following rules will not be
considered.</p>

<p>
You must make sure that the substitution string is a valid URI
(typically starting with <code>http://</code><em>hostname</em>) which can be
handled by the <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>. If not, you will get an
error from the proxy module. Use this flag to achieve a
more powerful implementation of the <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> directive,
to map remote content into the namespace of the local server.</p>

<div class="warning">
<h3>Security Warning</h3>
<p>Take care when constructing the target URL of the rule, considering
the security impact from allowing the client influence over the set of
URLs to which your server will act as a proxy.  Ensure that the scheme
and hostname part of the URL is either fixed, or does not allow the
client undue influence.</p>
</div>

<div class="warning">
<h3>Performance warning</h3>
<p>Using this flag triggers the use of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>, without handling of persistent connections. This
means the performance of your proxy will be better if you set it up with <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> or
<code class="directive"><a href="../mod/mod_proxy.html#proxypassmatch">ProxyPassMatch</a></code></p>
<p>This is because this flag triggers the use of the default worker, which does not handle connection pooling/reuse.</p>
<p>Avoid using this flag and prefer those directives, whenever you can.</p>
</div>

<p>Note: <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> must be enabled in order
to use this flag.</p>

<div class="section">
<h2><a name="flag_pt" id="flag_pt">PT|passthrough</a></h2>

<p>
The target (or substitution string) in a RewriteRule is assumed to be a
file path, by default. The use of the [PT] flag causes it to be treated
as a URI instead. That is to say, the
use of the [PT] flag causes the result of the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> to be passed back through
URL mapping, so that location-based mappings, such as <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code>, or <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>, for example, might have a
chance to take effect.
</p>

<p>
If, for example, you have an
<code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>
for /icons, and have a <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> pointing there, you should
use the [PT] flag to ensure that the
<code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> is evaluated.
</p>

<pre class="prettyprint lang-config">Alias "/icons" "/usr/local/apache/icons"
RewriteRule "/pics/(.+)\.jpg$" "/icons/$1.gif" [PT]</pre>


<p>
Omission of the [PT] flag in this case will cause the Alias to be
ignored, resulting in a 'File not found' error being returned.
</p>

<p>The <code>PT</code> flag implies the <code>L</code> flag:
rewriting will be stopped in order to pass the request to
the next phase of processing.</p>

<p>Note that the <code>PT</code> flag is implied in per-directory
contexts such as
<code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections
or in <code>.htaccess</code> files. The only way to circumvent that
is to rewrite to <code>-</code>.</p>

<div class="section">
<h2><a name="flag_qsa" id="flag_qsa">QSA|qsappend</a></h2>
<p>
When the replacement URI contains a query string, the default behavior
of <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> is to discard
the existing query string, and replace it with the newly generated one.
Using the [QSA] flag causes the query strings to be combined.
</p>

<p>Consider the following rule:</p>

<pre class="prettyprint lang-config">RewriteRule "/pages/(.+)" "/page.php?page=$1" [QSA]</pre>


<p>With the [QSA] flag, a request for <code>/pages/123?one=two</code> will be
mapped to <code>/page.php?page=123&amp;one=two</code>. Without the [QSA]
flag, that same request will be mapped to
<code>/page.php?page=123</code> - that is, the existing query string
will be discarded.

<div class="section">
<h2><a name="flag_qsd" id="flag_qsd">QSD|qsdiscard</a></h2>
<p>
When the requested URI contains a query string, and the target URI does
not, the default behavior of <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> is to copy that query
string to the target URI. Using the [QSD] flag causes the query string
to be discarded.
</p>

<p>This flag is available in version 2.4.0 and later.</p>

<p>
Using [QSD] and [QSA] together will result in [QSD] taking precedence.
</p>

<p>
If the target URI has a query string, the default behavior will be
observed - that is, the original query string will be discarded and
replaced with the query string in the <code>RewriteRule</code> target
URI.

<div class="section">
<h2><a name="flag_qsl" id="flag_qsl">QSL|qslast</a></h2>
<p>
By default, the first (left-most) question mark in the substitution
delimits the path from the query string.  Using the [QSL] flag instructs
<code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> to instead split
the two components using the last (right-most) question mark.  </p>

<p>
This is useful when mapping to files that have literal question marks in 
their filename.  If no query string is used in the substitution, 
a question mark can be appended to it in combination with this flag.  </p>

<p> This flag is available in version 2.4.19 and later.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_r" id="flag_r">R|redirect</a></h2>
<p>
Use of the [R] flag causes a HTTP redirect to be issued to the browser.
If a fully-qualified URL is specified (that is, including
<code>http://servername/</code>) then a redirect will be issued to that
location. Otherwise, the current protocol, servername, and port number
will be used to generate the URL sent with the redirect.
</p>

<p>
<em>Any</em> valid HTTP response  status code may be specified,
using the syntax [R=305], with a 302 status code being used by
default if none is specified. The status code specified need not
necessarily be a redirect (3xx) status code. However,
if a status code is outside the redirect range (300-399) then the
substitution string is dropped entirely, and rewriting is stopped as if
the <code>L</code> were used.</p>

<p>In addition to response status codes, you may also specify redirect
status using their symbolic names: <code>temp</code> (default),
<code>permanent</code>, or <code>seeother</code>.</p>

<p>
You will almost always want to use [R] in conjunction with [L] (that is,
use [R,L]) because on its own, the [R] flag prepends
<code>http://thishost[:thisport]</code> to the URI, but then passes this
on to the next rule in the ruleset, which can often result in 'Invalid
URI in request' warnings.
</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_s" id="flag_s">S|skip</a></h2>
<p>The [S] flag is used to skip rules that you don't want to run. The
syntax of the skip flag is [S=<em>N</em>], where <em>N</em> signifies
the number of rules to skip (provided the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">
RewriteRule</a></code> matches). This can be thought of as a <code>goto</code>
statement in your rewrite ruleset. In the following example, we only want
to run the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> if the
requested URI doesn't correspond with an actual file.</p>

<pre class="prettyprint lang-config"># Is the request for a non-existent file?
RewriteCond "%{REQUEST_FILENAME}" "!-f"
RewriteCond "%{REQUEST_FILENAME}" "!-d"
# If so, skip these two RewriteRules
RewriteRule ".?" "-" [S=2]

RewriteRule "(.*\.gif)" "images.php?$1"
RewriteRule "(.*\.html)" "docs.php?$1"</pre>


<p>This technique is useful because a <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> only applies to the
<code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> immediately
following it. Thus, if you want to make a <code>RewriteCond</code> apply
to several <code>RewriteRule</code>s, one possible technique is to
negate those conditions and add a <code>RewriteRule</code> with a [Skip] flag. You can
use this to make pseudo if-then-else constructs: The last rule of
the then-clause becomes <code>skip=N</code>, where N is the
number of rules in the else-clause:</p>
<pre class="prettyprint lang-config"># Does the file exist?
RewriteCond "%{REQUEST_FILENAME}" "!-f"
RewriteCond "%{REQUEST_FILENAME}" "!-d"
# Create an if-then-else construct by skipping 3 lines if we meant to go to the "else" stanza.
RewriteRule ".?" "-" [S=3]

# IF the file exists, then:
    RewriteRule "(.*\.gif)" "images.php?$1"
    RewriteRule "(.*\.html)" "docs.php?$1"
    # Skip past the "else" stanza.
    RewriteRule ".?" "-" [S=1]
# ELSE...
    RewriteRule "(.*)" "404.php?file=$1"
# END</pre>


<p>It is probably easier to accomplish this kind of configuration using
the <code class="directive">&lt;If&gt;</code>, <code class="directive">&lt;ElseIf&gt;</code>, and <code class="directive">&lt;Else&gt;</code> directives instead.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_t" id="flag_t">T|type</a></h2>
<p>Sets the MIME type with which the resulting response will be
sent. This has the same effect as the <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code> directive.</p>

<p>For example, you might use the following technique to serve Perl
source code as plain text, if requested in a particular way:</p>

<pre class="prettyprint lang-config"># Serve .pl files as plain text
RewriteRule "\.pl$" "-" [T=text/plain]</pre>


<p>Or, perhaps, if you have a camera that produces jpeg images without
file extensions, you could force those images to be served with the
correct MIME type by virtue of their file names:</p>

<pre class="prettyprint lang-config"># Files with 'IMG' in the name are jpg images.
RewriteRule "IMG" "-" [T=image/jpg]</pre>


<p>Please note that this is a trivial example, and could be better done
using <code class="directive"><a href="../mod/core.html#filesmatch">&lt;FilesMatch&gt;</a></code>
instead. Always consider the alternate
solutions to a problem before resorting to rewrite, which will
invariably be a less efficient solution than the alternatives.</p>

<p>
If used in per-directory context, use only <code>-</code> (dash)
as the substitution <em>for the entire round of mod_rewrite processing</em>,
otherwise the MIME-type set with this flag is lost due to an internal
re-processing (including subsequent rounds of mod_rewrite processing).
The <code>L</code> flag can be useful in this context to end the
<em>current</em> round of mod_rewrite processing.</p>

<h2><a name="introduction" id="introduction">Introduction</a></h2>
<p>Le module Apache <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> est un module puissant
et sophistiqué qui permet la réécriture des URLs. Grâce à lui, vous
pouvez effectuer quasiment tous les types de réécriture d'URLs dont vous
avez besoin. Il est cependant assez complexe, et peut paraître
intimidant au débutant. Certains ont aussi tendance à traiter les
règles de réécriture comme des incantations magiques, et à les utiliser
sans vraiment comprendre leur manière d'agir.</p>

<p>Ce document a pour ambition d'être suffisamment explicite pour
permettre la compréhension, et non la copie en aveugle, de ce qui suit.
</p>

<p>Gardez à l'esprit que de nombreuses tâches de manipulation d'URLs
courantes n'ont pas besoin de la puissance et de la complexité de
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>. Pour les tâches simples, voir
<code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> et la documentation sur la <a href="../urlmapping.html">Mise en correspondance des URLs avec le
système de fichiers</a>.</p>

<p>Enfin, avant de procéder, assurez-vous d'avoir configuré le niveau de
journalisation de <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> à un des niveaux de trace
via la directive <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code>. Bien que
ceci risque de vous submerger sous une énorme quantité d'informations,
le débogage des problèmes avec la configuration de
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> est à ce prix car vous verrez alors
exactement comment chaque règle est traitée.</p>

<div class="section">
<h2><a name="regex" id="regex">Expressions rationnelles</a></h2>

<p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> utilise le vocabulaire des <a href="http://pcre.org/">Expressions rationnelles compatibles Perl</a>.
Ce document n'a pas pour prétention d'être une référence détaillée des
expressions rationnelles. A cet effet, nous recommandons les <a href="http://pcre.org/pcre.txt">pages de manuel de PCRE</a>, la <a href="http://perldoc.perl.org/perlre.html">page de manuel des
expressions rationnelles Perl</a>, et l'ouvrage <a href="http://shop.oreilly.com/product/9780596528126.do">Mastering
Regular Expressions, by Jeffrey Friedl</a>.</p>

<p>Dans ce document, nous avons pour but de vous fournir suffisamment de
vocabulaire des expressions rationnelles pour vous mettre le pied à
l'étrier, sans être dépassé, en espérant que les directives <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> vous apparaîtront comme des
formules scientifiques, plutôt que comme des incantations magiques.</p>

<h3><a name="regexvocab" id="regexvocab">Vocabulaire des expressions rationnelles</a></h3>

<p>Vous trouverez dans ce qui suit le minimum à connaître pour être en
mesure d'écrire des expressions rationnelles et des règles <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>. Ceci ne représente
certainement pas un vocabulaire des expressions rationnelles complet,
mais constitue un bon point de départ, et devrait vous aider à
déchiffrer les expressions rationnelles simples, et à écrire vos propres
expressions.</p>

<p>Avec <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>, le caractère <code>!</code> peut
préfixer une expression rationnelle afin d'en exprimer la négation.
Autrement dit, une chaîne ne correspondra que si elle ne correspond pas
à l'expression située après le <code>!</code>.</p>



<h3><a name="InternalBackRefs" id="InternalBackRefs">Disponibilité des références
arrières dans les expressions rationnelles</a></h3>

      <p>Vous devez vous souvenir d'une chose importante : chaque fois
      que vous utilisez des parenthèses dans un <em>Modèle</em> ou dans
      un des <em>modèles de conditions</em>, des références arrières
      sont créées en interne et peuvent être rappelées via les chaînes
      <code>$N</code> et <code>%N</code> (voir ci-dessous). Ces
      références sont disponibles lors de la
      création de la chaîne de substitution d'une directive
      <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> ou de la
      chaîne de test d'une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code>.</p>
      <p>Les captures dans les modèles de directives <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> sont paradoxalement
      disponibles dans toutes les directives <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> qui précèdent, car
      les expressions des directives <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> sont évaluées avant
      les conditions individuelles.</p>
      
      <p>La figure 1 montre à quels endroits les
      références arrières sont suceptibles
      d'être développées, et illustre le flux des comparaisons
      effectuées par les règles RewriteRule et
      RewriteCond. Dans les chapitres suivants, nous examinerons comment
      utiliser ces références arrières, donc ne vous affolez pas si
      elles vous paraissent un peu exotiques au premier abord.</p>

<p class="figure">
      <img src="../images/rewrite_backreferences.png" alt="Flux des comparaisons effectuées par les règles RewriteRule       et RewriteCond" /><br />
      <dfn>Figure 1 :</dfn> Le cheminement d'une référence arrière à
      travers une règle.<br />
      Dans cet exemple, une requête pour <code>/test/1234</code> serait
      transformée en
      <code>/admin.foo?page=test&amp;id=1234&amp;host=admin.example.com</code>.
</p>


</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="rewriterule" id="rewriterule">Les bases des règles de réécriture</a></h2>
<p>Une règle de réécriture <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> est constituée de trois
arguments séparés par des espaces. Les arguments sont :</p>
<ol>
<li><var>Modèle</var>: le modèle des URLs auxquelles la règle doit
s'appliquer;</li>
<li><var>Substitution</var>: vers quoi la requête correspondante doit être
transformée;</li>
<li><var>[drapeaux]</var>: options affectant la requête réécrite.</li>
</ol>

<p>Le <var>Modèle</var> est une <a href="#regex">expression
rationnelle</a>. Au sein de la première règle de réécriture, ou jusqu'à
ce qu'une substitution survienne, elle est comparée au chemin de
l'URL de la requête entrante (la
partie située après le nom d'hôte mais avant tout point d'interrogation
qui indique le début d'une chaîne de paramètres de
requête) ou, dans un contexte de répertoire, au chemin de la
requête relativement au répertoire pour lequel la
règle est définie. Lorsqu'une substitution a eu lieu, les
règles suivantes effectuent leurs comparaisons par rapport à la valeur
substituée.</p>

<p class="figure">
      <img src="../images/syntax_rewriterule.png" alt="Syntaxe de la directive RewriteRule" /><br />
      <dfn>Figure 2 :</dfn> Syntaxe de la directive RewriteRule.
</p>

<p>La chaîne de <var>Substitution</var> peut, quant à elle, être de
trois types :</p>

<dl>
<dt>Un chemin complet du système de fichiers vers une ressource</dt>
<dd>
<pre class="prettyprint lang-config">RewriteRule "^/jeux" "/usr/local/jeux/web"</pre>

<p>Ceci peut faire correspondre une requête à toute localisation voulue de
votre système de fichiers, un peu comme la directive <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>.</p>
</dd>

<dt>Un chemin web vers une ressource</dt>
<dd>
<pre class="prettyprint lang-config">RewriteRule "^/foo$" "/bar"</pre>

<p>Si la directive <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> a
pour valeur <code>/usr/local/apache2/htdocs</code>, cette règle va faire
correspondre les requêtes pour <code>http://example.com/foo</code> au
chemin <code>/usr/local/apache2/htdocs/bar</code>.</p>
</dd>

<dt>Une URL absolue</dt>
<dd>
<pre class="prettyprint lang-config">RewriteRule "^/produits/vues$" "http://site2.example.com/voirproduits.html" [R]</pre>

<p>Ceci informe le client qu'il doit effectuer une nouvelle requête vers
l'URL spécifiée.</p>
</dd>
</dl>

<p>La chaîne de <var>Substitution</var> peut aussi contenir des
<em>références arrières</em> vers des parties du chemin d'URL entrant
correspondant au <var>Modèle</var>. Considérons ce qui suit :</p>
<pre class="prettyprint lang-config">RewriteRule "^/produits/(.*)/view$" "/var/web/produitsdb/$1"</pre>

<p>La variable <code>$1</code> sera remplacée par tout texte
correspondant à l'expression située entre les parenthèses dans le
<var>Modèle</var>. Par exemple, une requête pour
<code>http://example.com/produits/r14df/vue</code> correspondra au
chemin <code>/var/web/produitsdb/r14df</code>.</p>

<p>S'il y a plus d'une expression entre parenthèses, elle seront
accessibles selon leur ordre d'apparition via les variables
<code>$1</code>, <code>$2</code>, <code>$3</code>, etc...</p>


</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flags" id="flags">Drapeaux de réécriture</a></h2>
<p>Le comportement d'une règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> peut être modifié par la
présence d'un ou plusieurs drapeaux en fin de règle. Par exemple, les
conditions de correspondance d'une règle peuvent être rendues
insensibles à la casse par la présence du drapeau <code>[NC]</code> :
</p>
<pre class="prettyprint lang-config">RewriteRule "^puppy.html" "petitchien.html" [NC]</pre>


<p>Pour une liste des drapeaux disponibles, leurs significations, et des
exemples, voir le document <a href="flags.html">Drapeaux de
réécriture</a>.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="rewritecond" id="rewritecond">Conditions de réécriture</a></h2>
<p>Il est possible d'utiliser une ou plusieurs directives <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> pour restreindre les types
de requêtes auxquelles devra s'appliquer la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> suivante. Le premier
argument est une variable décrivant une caractéristique de la requête,
le second argument est une <a href="#regex">expression rationnelle</a>
qui doit correspondre à la variable, et un troisième argument optionnel
est une liste de drapeaux qui modifient la manière dont la
correspondance est évaluée.</p>

<p class="figure">
      <img src="../images/syntax_rewritecond.png" alt="Syntaxe de la directive RewriteCond" /><br />
      <dfn>Figure 3 :</dfn> Syntaxe de la directive RewriteCond
</p>


<p>Par exemple, pour renvoyer toutes les requêtes en provenance d'une
certaine tranche d'adresses IP vers un autre serveur, vous pouvez
utiliser :</p>
<pre class="prettyprint lang-config">RewriteCond "%{REMOTE_ADDR}" "^10\.2\."
RewriteRule "(.*)" "http://intranet.example.com$1"</pre>


<p>Si vous spécifiez plus d'une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code>, ces directives
doivent toutes être satisfaites pour que la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> suivante s'applique. Par exemple,
pour interdire les requêtes qui contiennent le mot "hack" dans la chaîne
de requête, sauf si elles contiennent aussi un cookie contenant le mot
"go", vous pouvez utiliser :</p>
<pre class="prettyprint lang-config">RewriteCond "%{QUERY_STRING}" "hack"
RewriteCond "%{HTTP_COOKIE}" "!go"
RewriteRule "." "-" [F]</pre>

<p>Notez que le point d'exclamation indique une correspondance négative
; ainsi, la règle n'est appliquée que si le cookie ne contient pas "go"</p>

<p>Les correspondances dans les expressions rationnelles contenues dans
les directives <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code>
peuvent constituer des parties de la chaîne de <var>Substitution</var>
de la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> via
les variables <code>%1</code>, <code>%2</code>, etc... Par
exemple, ce qui suit va diriger la requête vers un répertoire différent
en fonction du nom d'hôte utilisé pour accéder au site :</p>
<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "(.*)"
RewriteRule "^/(.*)" "/sites/%1/$1"</pre>

<p>Si la requête concernait <code>http://example.com/foo/bar</code>,
alors <code>%1</code> contiendrait <code>example.com</code> et
<code>$1</code> contiendrait <code>foo/bar</code>.</p>



</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="rewritemap" id="rewritemap">Tables de réécriture</a></h2>

<p>La directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>
permet en quelque sorte de faire appel à une fonction externe pour
effectuer la réécriture à votre place. Tout ceci est décrit plus en
détails dans la <a href="rewritemap.html">Documentation
supplémentaire sur RewriteMap</a>.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="htaccess" id="htaccess">Fichiers .htaccess</a></h2>

<p>La réécriture est en général définie au niveau de la configuration du
serveur principal (en dehors de toute section <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>) ou dans une section  <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>. Il s'agit là de la
manière la plus simple de mettre en oeuvre la réécriture et nous la
recommandons. Il est possible, cependant, de mettre en oeuvre la
réécriture au sein d'une section <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> ou d'un fichier <a href="../howto/htaccess.html"><code>.htaccess</code></a> ; ce type de
configuration est cependant plus complexe. Cette technique est appelée
réécriture par répertoire.</p>

<p>La principale différence avec les réécritures au niveau du serveur réside
dans le fait que le préfixe du chemin du répertoire contenant le fichier
<code>.htaccess</code> est supprimé avant la mise en correspondance dans
la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>. De
plus, on doit utiliser la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> pour s'assurer que la
requête est correctement mise en correspondance.</p>

    <dd>
    <p>Cet exemple utilise une fonctionnalité souvent méconnue de
    mod_rewrite, en tirant avantage de l'ordre d'exécution du jeu de
    règles. En particulier, mod_rewrite évalue la partie gauche des
    règles de réécriture avant d'évaluer les directives RewriteCond. En
    conséquence, $1 est déjà défini au moment où les directives
    RewriteCond sont évaluées. Ceci nous permet de tester l'existence du
    fichier original (<code>document.html</code>) et du fichier cible
    (<code>document.php</code>) en utilisant le même nom de base.</p>

    <p>Ce jeu de règles est conçu pour une utilisation dans un contexte
    de répertoire (au sein d'une section &lt;Directory&gt; ou d'un
    fichier .htaccess), de façon à ce que les vérifications
    <code>-f</code> effectuent leurs recherches dans le bon répertoire.
    Vous serez peut-être amené à définir une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> pour spécifier le
    répertoire de base à partir duquel vous travaillez.</p>

        <dd>Le but de cette règle est de préférer l'utilisation d'un nom

        <dt>Solution :</dt>

        <dd>

<p>Pour y parvenir, il vaut mieux se passer de mod_rewrite, et utiliser
plutôt la directive <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code> dans
une section de serveur virtuel pour le/les noms d'hôte non canoniques.</p>

<pre class="prettyprint lang-config">&lt;VirtualHost *:80&gt;
  ServerName undesired.example.com
  ServerAlias example.com notthis.example.com

  Redirect "/" "http://www.example.com/"
&lt;/VirtualHost&gt;

&lt;VirtualHost *:80&gt;
  ServerName www.example.com
&lt;/VirtualHost&gt;</pre>


<p>Vous pouvez aussi utiliser la directive <code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code> :</p>

<pre class="prettyprint lang-config">&lt;If "%{HTTP_HOST} != 'www.example.com'"&gt;
	Redirect "/" "http://www.example.com/"
&lt;/If&gt;</pre>


<p>Ou, par exemple, pour rediriger une portion de votre site vers HTTPS
:</p>

<pre class="prettyprint lang-config">&lt;If "%{SERVER_PROTOCOL} != 'HTTPS'"&gt;
	Redirect "/admin/" "https://www.example.com/admin/"
&lt;/If&gt;</pre>


<p>Si, pour une raison particulière, vous voulez tout de même utiliser
<code>mod_rewrite</code> - dans le cas, par exemple, où vous avez besoin
d'un jeu plus important de règles de réécritures - vous pouvez utiliser
la recette suivante :</p>

<p>Pour les sites écoutant sur un port autre que 80:</p>
<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}"   "!^www\.example\.com" [NC]
RewriteCond "%{HTTP_HOST}"   "!^$"
RewriteCond "%{SERVER_PORT}" "!^80$"
RewriteRule "^/?(.*)"         "http://www.example.com:%{SERVER_PORT}/$1" [L,R,NE]</pre>


<p>Et pour un site écoutant sur le port 80</p>
<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}"   "!^www\.example\.com" [NC]
RewriteCond "%{HTTP_HOST}"   "!^$"
RewriteRule "^/?(.*)"         "http://www.example.com/$1" [L,R,NE]</pre>

	<p>
	Si vous souhaitez que cette règle s'applique à tous les noms de
	domaine - en d'autres termes, si vous voulez rediriger
	<strong>example.com</strong> vers
	<strong>www.example.com</strong> pour toutes les valeurs
	possibles de <strong>example.com</strong>, vous pouvez utiliser
	le jeu de règles suivants :</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "!^www\." [NC]
RewriteCond "%{HTTP_HOST}" "!^$"
RewriteRule "^/?(.*)" "http://www.%{HTTP_HOST}/$1" [L,R,NE]</pre>

	<p>
	Vous pouvez utiliser ce jeu de règles aussi bien dans le fichier
	de configuration de votre serveur principal que dans un fichier
	<code>.htaccess</code> placé dans le répertoire défini par la
	directive <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> du serveur.</p>

<p>Notez que l'on peut aussi y parvenir en utilisant la directive
<code class="directive"><a href="../mod/mod_alias.html#redirectmatch">RedirectMatch</a></code> :</p>

<pre class="prettyprint lang-config">RedirectMatch "^/$" "http://example.com/a-propos-de/"</pre>


<p>Notez aussi que cet exemple ne réécrit que l'URL racine. En d'autres
termes, il réécrit une requête pour <code>http://example.com/</code>,
mais pas pour une requête <code>http://example.com/page.html</code>. Si
vous avez effectivement modifié la racine de vos documents - c'est à dire
si <strong>tous</strong> vos contenus se trouvent dans un
sous-répertoire, il est largement préférable de modifier simplement
votre directive <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>, ou de
déplacer l'ensemble du contenu vers le répertoire supérieur, plutôt que
de réécrire les URLs.</p>

<div class="section">
<h2><a name="fallback-resource" id="fallback-resource">Ressource par défaut</a></h2>


<dl>
<dt>Description :</dt>
<dd>Vous voulez qu'une seule ressource (disons un certain fichier tel
que index.php) soit servie pour toutes les requêtes à destination d'un
certain répertoire, sauf pour celles qui concernent une ressource
existant effectivement comme une image, ou un fichier css.</dd>

<dt>Solution :</dt>
<dd>
<p>Depuis la version 2.2.16, vous pouvez y parvenir via la directive
<code class="directive"><a href="../mod/mod_dir.html#fallbackresource">FallbackResource</a></code> :</p>

<pre class="prettyprint lang-config">&lt;Directory "/var/www/my_blog"&gt;
  FallbackResource "index.php"
&lt;/Directory&gt;</pre>


<p>Cependant, si vos besoins étaient plus complexes, vous pouviez, dans
les versions plus anciennes d'Apache, utiliser un jeu de règles du style
:</p>

<pre class="prettyprint lang-config">&lt;Directory "/var/www/my_blog"&gt;
  RewriteBase "/my_blog"

  RewriteCond "/var/www/my_blog/%{REQUEST_FILENAME}" !-f
  RewriteCond "/var/www/my_blog/%{REQUEST_FILENAME}" !-d
  RewriteRule "^" "index.php" [PT]
&lt;/Directory&gt;</pre>


<p>D'autre part, si vous voulez transmettre l'URI de la requête en tant
que chaîne de paramètres à index.php, vous pouvez remplacer cette règle
de réécriture par :</p>

<pre class="prettyprint lang-config">RewriteRule "(.*)" "index.php?$1" [PT,QSA]</pre>


<p>Notez que l'on peut utiliser ces jeux de règles aussi bien dans un
fichier <code>.htaccess</code> que dans une section
&lt;Directory&gt;.</p>

<div class="section">
<h2><a name="rewrite-query" id="rewrite-query">Rewrite query string</a></h2>


<dl>
<dt>Description :</dt>
<dd>Vous voulez extraire une valeur particulière d'une chaîne de
paramètres d'une URL, et soit la remplacer, soit l'incorporer dans un
autre composant de l'URL.</dd>

<dt>Solutions :</dt>
<dd>
<p>Dans la plupart des solutions de cette section, on utilise la même
condition qui stocke la valeur recherchée dans la référence arrière %2.
%1 est le début de la requête, et %3 ce qui reste. Cette condition est
un peu complexe car elle introduit de la flexibilité et évite les
doubles perluettes '&amp;&amp;' dans les substitutions.</p>
<ul>
  <li>Cette solution supprime le couple clé/valeur recherché :

<pre class="prettyprint lang-config"># Remove mykey=???
RewriteCond "%{QUERY_STRING}" "(.*(?:^|&amp;))mykey=([^&amp;]*)&amp;?(.*)&amp;?$"
RewriteRule "(.*)" "$1?%1%3"</pre>

  </li>

  <li>Cette solution remplace la partie de l'URL qui suit la valeur
  recherchée par un '?' :

<pre class="prettyprint lang-config"># Copy from query string to PATH_INFO
RewriteCond "%{QUERY_STRING}" "(.*(?:^|&amp;))mykey=([^&amp;]*)&amp;?(.*)&amp;?$"
RewriteRule "(.*)" "$1/products/%2/?" [PT]</pre>

  </li>

  <li>Cette solution utilise la valeur recherchée dans une deuxième
  condition ::

<pre class="prettyprint lang-config"># Capture the value of mykey in the query string
RewriteCond "%{QUERY_STRING}" "(.*(?:^|&amp;))mykey=([^&amp;]*)&amp;?(.*)&amp;?$""
RewriteCond "%2" !=not-so-secret-value 
RewriteRule "(.*)" - [F]</pre>

  </li>

  <li>Cette solution produit l'effet inverse des précédentes ; elle
  copie des composantes du chemin (peut-être PATH_INFO) depuis l'URL
  vers sa chaîne de paramètres :
<pre class="prettyprint lang-config"># The desired URL might be /products/kitchen-sink, and the script expects 
# /path?products=kitchen-sink.
RewriteRule "^/?path/([^/]+)/([^/]+)" "/path?$1=$2" [PT]</pre>

  </li>
</ul>

    <p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> provides a way to modify incoming
    URL requests, dynamically, based on <a href="intro.html#regex">regular
    expression</a> rules. This allows you to map arbitrary URLs onto
    your internal URL structure in any way you like.</p>

      <p>It supports an unlimited number of rules and an
      unlimited number of attached rule conditions for each rule to
      provide a really flexible and powerful URL manipulation
      mechanism. The URL manipulations can depend on various tests:
      server variables, environment variables, HTTP
      headers, time stamps, external database lookups, and various other
      external programs or handlers, can be used to achieve granular URL
      matching.</p>

      <p>Rewrite rules can operate on the full URLs, including the path-info
      and query string portions, and may be used in per-server context
      (<code>httpd.conf</code>), per-virtualhost context (<code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code> blocks), or
      per-directory context (<code>.htaccess</code> files and <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> blocks). The
      rewritten result can lead to further rules, internal
      sub-processing, external request redirection, or proxy
      passthrough, depending on what <a href="flags.html">flags</a> you
      attach to the rules.</p>

      <p>Since mod_rewrite is so powerful, it can indeed be rather
      complex. This document supplements the <a href="../mod/mod_rewrite.html">reference documentation</a>, and
      attempts to allay some of that complexity, and provide highly
      annotated examples of common scenarios that you may handle with
      mod_rewrite. But we also attempt to show you when you should not
      use mod_rewrite, and use other standard Apache features instead,
      thus avoiding this unnecessary complexity.</p>

<h2><a name="sharding" id="sharding">Distribution de la charge entre plusieurs serveurs
  d'arrière-plan en fonction de l'adresse IP</a></h2>

  

  <dl>
    <dt>Description :</dt>

    <dd>
      <p>La fragmentation ou "sharding" est une technique courante de
      distribution de la charge du serveur ou de l'espace de stockage.
      Quand on utilise cette méthode, un serveur frontal utilise l'URL
      pour répartir de manière appropriée les utilisateurs et objets
      entre différents serveurs d'arrière-plan.</p>
    </dd>

    <dt>Solution :</dt>

    <dd>
      <p>On maintient une table de correspondance entre utilisateurs et
      serveurs cibles dans des fichiers externes. Ces derniers se
      présentent comme suit :</p>

<div class="example"><p><code>
utilisateur1  serveur_physique_utilisateur1<br />
utilisateur2  serveur_physique_utilisateur2<br />
:      :
</code></p></div>

  <p>Tout ceci est enregistré dans un fichier
  <code>correspondances-utilisateurs-serveurs</code>. Le but est de
  faire correspondre</p>

<div class="example"><p><code>
/u/utilisateur1/chemin
</code></p></div>

  <p>avec</p>

<div class="example"><p><code>
http://serveur_physique_utilisateur1/u/utilisateur/chemin
</code></p></div>

      <p>il n'est ainsi pas nécessaire que tous les chemins URL soient
      valides sur tous les serveurs physiques d'arrière-plan. Le jeu de
      règles suivant fait tout ceci pour nous, en s'appuyant sur les
      fichiers de correspondances, en supposant que serveur0 est un
      serveur par défaut qui sera utilisé lorsqu'un utilisateur ne
      possèdera pas d'entrée dans la table de correspondances :</p>

<pre class="prettyprint lang-config">RewriteEngine on
RewriteMap    users-to-hosts      "txt:/path/to/map.users-to-hosts"
RewriteRule   "^/u/([^/]+)/?(.*)" "http://${users-to-hosts:$1|server0}/u/$1/$2"</pre>

    </dd>
  </dl>

  <p>Voir la documentation de <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> pour une description plus
  approfondie de la syntaxe de cette directive.</p>

    <dt>Description :</dt>

    <dd>
      <p>Nous voulons générer du contenu de manière dynamique, mais le
      conserver de manière statique lorsqu'il a été généré. La règle
      suivante vérifie l'existence du fichier statique, et le génère
      s'il est absent. Les fichiers statiques peuvent être supprimés
      périodiquement si on le désire (par exemple via cron), et seront
      régénérés à la demande.</p>
    </dd>

    <dt>Solution :</dt>

    <dd>
      A cet effet, on utilise le jeu de règles suivant :

<pre class="prettyprint lang-config"># Cet exemple n'est valable que dans un contexte de répertoire
RewriteCond "%{REQUEST_URI}"   "!-U"
RewriteRule "^(.+)\.html$"     "/regenerate_page.cgi"   [PT,L]</pre>


      <p>L'opérateur <code>-U</code> permet de déterminer si la chaîne
      de test (dans ce cas <code>REQUEST_URI</code>) est une URL valide.
      Pour ce faire, il utilise une sous-requête. Si cette sous-requête
      échoue, ou en d'autres termes, si la ressource demandée n'existe pas,
      cette règle invoque le programme CGI
      <code>/regenerate_page.cgi</code> qui génère la ressource
      demandée et la sauvegarde dans le répertoire des documents, de
      façon à ce qu'une copie statique puisse être servie lors d'une
      demande ultérieure.</p>

    <p>De cette façon, les documents qui ne sont pas mis à jour
    régulièrement peuvent être servis sous une forme statique. Si ces
    documents doivent être réactualisés, on peut les supprimer du
    répertoire des documents, et ils seront ainsi régénérés à la
    prochaine demande.</p>

    <dd>
      <p>Pour y parvenir, nous allons utiliser la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> et une liste de

<p>Apache possède un module de répartition de charge -
<code class="module"><a href="../mod/mod_proxy_balancer.html">mod_proxy_balancer</a></code> - beaucoup plus souple et présentant

    <dt>Solution :</dt>

    <dd>
      <p>Il existe de nombreuses variables nommées
	  <code>TIME_xxx</code> utilisables dans les conditions de
	  réécriture. Utilisées en conjonction avec les modèles de
	  comparaison lexicographique spéciaux <code>&lt;STRING</code>,
	  <code>&gt;STRING</code> et <code>=STRING</code>, elles
	  permettent d'effectuer des redirections dépendant de
	  l'heure :</p>

<pre class="prettyprint lang-config">RewriteEngine on

RewriteRule   "^foo\.html$"             "foo.night.html"</pre>


      <p>Avec cet exemple, l'URL <code>foo.html</code> renvoie
	  le contenu de <code>foo.jour.html</code> durant le

<h2><a name="introduction" id="introduction">Introduction</a></h2>
<p>The Apache module <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> is a very powerful and
sophisticated module which provides a way to do URL manipulations. With
it, you can do nearly all types of URL rewriting that you may need. It
is, however, somewhat complex, and may be intimidating to the beginner.
There is also a tendency to treat rewrite rules as magic incantation,
using them without actually understanding what they do.</p>

<p>This document attempts to give sufficient background so that what
follows is understood, rather than just copied blindly.
</p>

<p>Remember that many common URL-manipulation tasks don't require the
full power and complexity of <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>. For simple
tasks, see <code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> and the documentation
on <a href="../urlmapping.html">mapping URLs to the
filesystem</a>.</p>

<p>Finally, before proceeding, be sure to configure
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>'s log level to one of the trace levels using
the <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code> directive. Although this
can give an overwhelming amount of information, it is indispensable in
debugging problems with <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> configuration, since
it will tell you exactly how each rule is processed.</p>

<h2><a name="regex" id="regex">Regular Expressions</a></h2>

<p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> uses the <a href="http://pcre.org/">Perl Compatible
Regular Expression</a> vocabulary. In this document, we do not attempt
to provide a detailed reference to regular expressions. For that, we
recommend the <a href="http://pcre.org/pcre.txt">PCRE man pages</a>, the
<a href="http://perldoc.perl.org/perlre.html">Perl regular
expression man page</a>, and <a href="http://shop.oreilly.com/product/9780596528126.do">Mastering
Regular Expressions, by Jeffrey Friedl</a>.</p>

<p>In this document, we attempt to provide enough of a regex vocabulary
to get you started, without being overwhelming, in the hope that
<code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>s will be scientific
formulae, rather than magical incantations.</p>

<h3><a name="regexvocab" id="regexvocab">Regex vocabulary</a></h3>

<p>The following are the minimal building blocks you will need, in order
to write regular expressions and <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>s. They certainly do not
represent a complete regular expression vocabulary, but they are a good
place to start, and should help you read basic regular expressions, as
well as write your own.</p>

<p>In <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> the <code>!</code> character can be
used before a regular expression to negate it. This is, a string will
be considered to have matched only if it does not match the rest of
the expression.</p>



<h3><a name="InternalBackRefs" id="InternalBackRefs">Regex Back-Reference Availability</a></h3>

      <p>One important thing here has to be remembered: Whenever you
      use parentheses in <em>Pattern</em> or in one of the
      <em>CondPattern</em>, back-references are internally created
      which can be used with the strings <code>$N</code> and
      <code>%N</code> (see below). These are available for creating
      the <em>Substitution</em> parameter of a
      <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> or
      the <em>TestString</em> parameter of a
      <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code>.</p>
      <p>  Captures in the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> patterns are (counterintuitively) available to
       all preceding
      <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> directives,
      because the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>
      expression is evaluated before the individual conditions.</p>

      <p>Figure 1 shows to which
      locations the back-references are transferred for expansion as
      well as illustrating the flow of the RewriteRule, RewriteCond
      matching. In the next chapters, we will be exploring how to use
      these back-references, so do not fret if it seems a bit alien
      to you at first.

<h2><a name="rewriterule" id="rewriterule">RewriteRule Basics</a></h2>
<p>A <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> consists
of three arguments separated by spaces. The arguments are</p>
<ol>
<li><var>Pattern</var>: which incoming URLs should be affected by the rule;</li>
<li><var>Substitution</var>: where should the matching requests be sent;</li>
<li><var>[flags]</var>: options affecting the rewritten request.</li>
</ol>

<p>The <var>Pattern</var> is a <a href="#regex">regular expression</a>.
It is initially (for the first rewrite rule or until a substitution occurs)
matched against the URL-path of the incoming request (the part after the
hostname but before any question mark indicating the beginning of a query
string) or, in per-directory context, against the request's path relative
to the directory for which the rule is defined. Once a substitution has
occurred, the rules that follow are matched against the substituted
value.
</p>

<p class="figure">
      <img src="../images/syntax_rewriterule.png" alt="Syntax of the RewriteRule directive" /><br />
      <dfn>Figure 2:</dfn> Syntax of the RewriteRule directive.
</p>


<p>The <var>Substitution</var> can itself be one of three things:</p>

<dl>
<dt>A full filesystem path to a resource</dt>
<dd>
<pre class="prettyprint lang-config">RewriteRule "^/games" "/usr/local/games/web"</pre>

<p>This maps a request to an arbitrary location on your filesystem, much
like the <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> directive.</p>
</dd>

<dt>A web-path to a resource</dt>
<dd>
<pre class="prettyprint lang-config">RewriteRule "^/foo$" "/bar"</pre>

<p>If <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> is set
to <code>/usr/local/apache2/htdocs</code>, then this directive would
map requests for <code>http://example.com/foo</code> to the
path <code>/usr/local/apache2/htdocs/bar</code>.</p>
</dd>

<dt>An absolute URL</dt>
<dd>
<pre class="prettyprint lang-config">RewriteRule "^/product/view$" "http://site2.example.com/seeproduct.html" [R]</pre>

<p>This tells the client to make a new request for the specified URL.</p>
</dd>
</dl>

<p>The <var>Substitution</var> can also
contain <em>back-references</em> to parts of the incoming URL-path
matched by the <var>Pattern</var>. Consider the following:</p>
<pre class="prettyprint lang-config">RewriteRule "^/product/(.*)/view$" "/var/web/productdb/$1"</pre>

<p>The variable <code>$1</code> will be replaced with whatever text
was matched by the expression inside the parenthesis in
the <var>Pattern</var>. For example, a request
for <code>http://example.com/product/r14df/view</code> will be mapped
to the path <code>/var/web/productdb/r14df</code>.</p>

<p>If there is more than one expression in parenthesis, they are
available in order in the
variables <code>$1</code>, <code>$2</code>, <code>$3</code>, and so
on.</p>

<div class="section">
<h2><a name="flags" id="flags">Rewrite Flags</a></h2>
<p>The behavior of a <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> can be modified by the
application of one or more flags to the end of the rule. For example, the
matching behavior of a rule can be made case-insensitive by the
application of the <code>[NC]</code> flag:
</p>
<pre class="prettyprint lang-config">RewriteRule "^puppy.html" "smalldog.html" [NC]</pre>


<p>For more details on the available flags, their meanings, and
examples, see the <a href="flags.html">Rewrite Flags</a> document.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="rewritecond" id="rewritecond">Rewrite Conditions</a></h2>
<p>One or more <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code>
directives can be used to restrict the types of requests that will be
subject to the
following <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>. The
first argument is a variable describing a characteristic of the
request, the second argument is a <a href="#regex">regular
expression</a> that must match the variable, and a third optional
argument is a list of flags that modify how the match is evaluated.</p>

<p class="figure">
      <img src="../images/syntax_rewritecond.png" alt="Syntax of the RewriteCond directive" /><br />
      <dfn>Figure 3:</dfn> Syntax of the RewriteCond directive
</p>

<p>For example, to send all requests from a particular IP range to a
different server, you could use:</p>
<pre class="prettyprint lang-config">RewriteCond "%{REMOTE_ADDR}" "^10\.2\."
RewriteRule "(.*)"           "http://intranet.example.com$1"</pre>


<p>When more than
one <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> is
specified, they must all match for
the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> to be
applied. For example, to deny requests that contain the word "hack" in
their query string, unless they also contain a cookie containing
the word "go", you could use:</p>
<pre class="prettyprint lang-config">RewriteCond "%{QUERY_STRING}" "hack"
RewriteCond "%{HTTP_COOKIE}"  !go
RewriteRule "."               "-"   [F]</pre>

<p>Notice that the exclamation mark specifies a negative match, so the rule is only applied if the cookie does not contain "go".</p>

<p>Matches in the regular expressions contained in
the <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code>s can be
used as part of the <var>Substitution</var> in
the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> using the
variables <code>%1</code>, <code>%2</code>, etc. For example, this
will direct the request to a different directory depending on the
hostname used to access the site:</p>
<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "(.*)"
RewriteRule "^/(.*)"       "/sites/%1/$1"</pre>

<p>If the request was for <code>http://example.com/foo/bar</code>,
then <code>%1</code> would contain <code>example.com</code>
and <code>$1</code> would contain <code>foo/bar</code>.</p>

<h2><a name="rewritemap" id="rewritemap">Rewrite maps</a></h2>

<p>The <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> directive
provides a way to call an external function, so to speak, to do your
rewriting for you. This is discussed in greater detail in the <a href="rewritemap.html">RewriteMap supplementary documentation</a>.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="htaccess" id="htaccess">.htaccess files</a></h2>

<p>Rewriting is typically configured in the main server configuration
setting (outside any <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> section) or
inside <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
containers. This is the easiest way to do rewriting and is
recommended. It is possible, however, to do rewriting
inside <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>
sections or <a href="../howto/htaccess.html"><code>.htaccess</code>
files</a> at the expense of some additional complexity. This technique
is called per-directory rewrites.</p>

<p>The main difference with per-server rewrites is that the path
prefix of the directory containing the <code>.htaccess</code> file is
stripped before matching in
the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>. In addition, the <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> should be used to assure the request is properly mapped.</p>

    <dd>
    <p>Nous voulons créer automatiquement un serveur virtuel pour tout
    nom d'hôte qui peut être résolu dans notre domaine, sans avoir à
    créer de nouvelle section VirtualHost.</p>

    <p>Dans cet exemple, nous supposons que nous utilisons le nom d'hôte
    <code>www.<strong>SITE</strong>.example.com</code> pour chaque
    utilisateur, et que nous servons leur contenu depuis
    <code>/home/<strong>SITE</strong>/www</code>.</p>

    <div class="warning">Vous devez vérifier le bon fonctionnement de la
    résolution DNS - Apache ne gère pas la résolution de nom. Vous
    devrez créer soit des enregistrements CNAME pour chaque nom d'hôte,
    soit un enregistrement DNS avec caractères génériques. La création
    des enregistrements DNS est en dehors du sujet de ce document.</div>

<p>La directive RewriteMap interne <code>tolower</code> permet de
s'assurer que les noms d'hôtes utilisés seront tous en minuscules, de
façon à éviter toute ambiguité dans la structure des répertoires qui
doit être créée.</p>

<p>Les contenus des parenthèses utilisées dans une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> sont enregistrés dans les
références arrières <code>%1</code>, <code>%2</code>, etc..., alors que
les contenus des parenthèses utilisées dans une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> le sont dans les
références arrières <code>$1</code>, <code>$2</code>, etc...</p>

<p>
Comme c'est le cas pour de nombreuses techniques discutées dans ce
document, mod_rewrite n'est vraiment pas la meilleure méthode pour
accomplir cette tâche. Vous devez plutôt vous tourner vers
<code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code>, car ce dernier sera bien plus à même
de gérer tout ce qui est au delà du domaine des fichiers statiques,
comme les contenus dynamiques et la résolution des alias.

    <p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> 提供了基于<a href="intro.html#regex">正则表达式</a>规则动态修改传入的请求的 URL 的方法。
    这允许你以自己喜欢的任意方法映射任意 URL 到你的内部 URL 结构。</p>

    <p>它支持无限的规则，以及为每个规则附加条件，从而提供了一个真正灵活且强大的 URL
    操作机制。URL 操作可以依赖于各种测试，例如服务器变量，环境变量，HTTP
    头，时戳，甚至外部数据库查询等，以便完成 URL 单元匹配。</p>

    <p>这个模块在服务器上下文 (<code>httpd.conf</code>)，虚拟主机上下文 (<code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code> 指令块)，目录上下文
    (<code>.htaccess</code> 文件和 <code>&lt;Directory&gt;</code>
    指令块) 对完整的 URL (包含目录信息部分和查询字符串部分) 操作。
    重写结果可以导致新的规则处理，内部的后续处理，外部请求重定向，甚至透过内部代理，
    这取决于你为规则附加的<a href="flags.html">标志</a>。</p>

    <p>既然 mod_rewrite 这么强大，它当然是相当复杂。这篇文档作为<a href="../mod/mod_rewrite.html">参考手册</a>的补充，试图减轻一些复杂性，
    提供你可能使用 mod_rewrite 的常见场景的有充分注释的例子。
    但是，我们也试图告诉你，在什么时候你不应当使用 mod_rewrite，
    可以使用其它标准的 Apache 特性来达到目的，以避免无谓的复杂性。</p>

<h2><a name="per-hostname" id="per-hostname">Virtual Hosts For Arbitrary Hostnames</a></h2>

  

  <dl>
    <dt>Description:</dt>

    <dd>
    <p>We want to automatically create a virtual host for every hostname
    which resolves in our domain, without having to create
    new VirtualHost sections.</p>

    <p>In this recipe, we assume that we'll be using the hostname
    <code>www.<strong>SITE</strong>.example.com</code> for each
    user, and serve their content out of
    <code>/home/<strong>SITE</strong>/www</code>.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>

<pre class="prettyprint lang-config">RewriteEngine on

RewriteMap    lowercase int:tolower

RewriteCond   "${lowercase:%{<strong>HTTP_HOST</strong>}}"   "^www\.<strong>([^.]+)</strong>\.example\.com$"
RewriteRule   "^(.*)" "/home/<strong>%1</strong>/www$1"</pre>
</dd>

<dt>Discussion</dt>
    <dd>

    <div class="warning">You will need to take care of the DNS
    resolution - Apache does
    not handle name resolution. You'll need either to create CNAME
    records for each hostname, or a DNS wildcard record. Creating DNS
    records is beyond the scope of this document.</div>

<p>The internal <code>tolower</code> RewriteMap directive is used to
ensure that the hostnames being used are all lowercase, so that there is
no ambiguity in the directory structure which must be created.</p>

<p>Parentheses used in a <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> are captured into the
backreferences <code>%1</code>, <code>%2</code>, etc, while parentheses
used in <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> are
captured into the backreferences <code>$1</code>, <code>$2</code>,
etc.</p>

<p>
As with many techniques discussed in this document, mod_rewrite really
isn't the best way to accomplish this task. You should, instead,
consider using <code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code> instead, as it will much
more gracefully handle anything beyond serving static files, such as any
dynamic content, and Alias resolution.
</p>
    </dd>

<div class="section">
<h2><a name="simple.rewrite" id="simple.rewrite">Dynamic
    Virtual Hosts Using <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code></a></h2>

    <p>This extract from <code>httpd.conf</code> does the same
    thing as <a href="#per-hostname">the first example</a>. The first
    half is very similar to the corresponding part above, except for
    some changes, required for backward compatibility and to make the
    <code>mod_rewrite</code> part work properly; the second half
    configures <code>mod_rewrite</code> to do the actual work.</p>

    <p>Because <code>mod_rewrite</code> runs before other URI translation
    modules (e.g., <code>mod_alias</code>), <code>mod_rewrite</code> must
    be told to explicitly ignore any URLs that would have been handled
    by those modules. And, because these rules would otherwise bypass
    any <code>ScriptAlias</code> directives, we must have
    <code>mod_rewrite</code> explicitly enact those mappings.</p>

<pre class="prettyprint lang-config"># get the server name from the Host: header
UseCanonicalName Off

# splittable logs
LogFormat "%{Host}i %h %l %u %t \"%r\" %s %b" vcommon
CustomLog "logs/access_log" vcommon

&lt;Directory "/www/hosts"&gt;
    # ExecCGI is needed here because we can't force
    # CGI execution in the way that ScriptAlias does
    Options FollowSymLinks ExecCGI
&lt;/Directory&gt;

RewriteEngine On

# a ServerName derived from a Host: header may be any case at all
RewriteMap  lowercase  int:tolower

## deal with normal documents first:
# allow Alias "/icons/" to work - repeat for other aliases
RewriteCond  "%{REQUEST_URI}"  "!^/icons/"
# allow CGIs to work
RewriteCond  "%{REQUEST_URI}"  "!^/cgi-bin/"
# do the magic
RewriteRule  "^/(.*)$"  "/www/hosts/${lowercase:%{SERVER_NAME}}/docs/$1"

## and now deal with CGIs - we have to force a handler
RewriteCond  "%{REQUEST_URI}"  "^/cgi-bin/"
RewriteRule  "^/(.*)$"  "/www/hosts/${lowercase:%{SERVER_NAME}}/cgi-bin/$1"  [H=cgi-script]</pre>

<div class="section">
<h2><a name="xtra-conf" id="xtra-conf">Using a Separate Virtual Host Configuration File</a></h2>

    <p>This arrangement uses more advanced <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>
    features to work out the translation from virtual host to document
    root, from a separate configuration file. This provides more
    flexibility, but requires more complicated configuration.</p>

    <p>The <code>vhost.map</code> file should look something like
    this:</p>

<div class="example"><p><code>
customer-1.example.com  /www/customers/1<br />
customer-2.example.com  /www/customers/2<br />
# ...<br />
customer-N.example.com  /www/customers/N<br />
</code></p></div>

    <p>The <code>httpd.conf</code> should contain the following:</p>

<pre class="prettyprint lang-config">RewriteEngine on

RewriteMap   lowercase  int:tolower

# define the map file
RewriteMap   vhost      "txt:/www/conf/vhost.map"

# deal with aliases as above

RewriteCond  "%{REQUEST_URI}"               "!^/cgi-bin/"
RewriteCond  "${lowercase:%{SERVER_NAME}}"  "^(.+)$"
# this does the file-based remap
RewriteCond  "${vhost:%1}"                  "^(/.*)$"
RewriteRule  "^/(.*)$"                      "%1/docs/$1"

RewriteCond  "%{REQUEST_URI}"               "^/cgi-bin/"
RewriteCond  "${lowercase:%{SERVER_NAME}}"  "^(.+)$"
RewriteCond  "${vhost:%1}"                  "^(/.*)$"

<h2><a name="sharding" id="sharding">URL-based sharding across multiple backends</a></h2>

  

  <dl>
    <dt>Description:</dt>

    <dd>
      <p>A common technique for distributing the burden of
      server load or storage space is called "sharding".
      When using this method, a front-end server will use the
      url to consistently "shard" users or objects to separate
      backend servers.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      <p>A mapping is maintained, from users to target servers, in
      external map files. They look like:</p>

<div class="example"><p><code>
user1  physical_host_of_user1<br />
user2  physical_host_of_user2<br />
:      :
</code></p></div>

  <p>We put this into a <code>map.users-to-hosts</code> file. The
    aim is to map;</p>

<div class="example"><p><code>
/u/user1/anypath
</code></p></div>

  <p>to</p>

<div class="example"><p><code>
http://physical_host_of_user1/u/user/anypath
</code></p></div>

      <p>thus every URL path need not be valid on every backend physical
      host. The following ruleset does this for us with the help of the map
      files assuming that server0 is a default server which will be used if
      a user has no entry in the map:</p>

<pre class="prettyprint lang-config">RewriteEngine on
RewriteMap    users-to-hosts      "txt:/path/to/map.users-to-hosts"
RewriteRule   "^/u/([^/]+)/?(.*)" "http://${users-to-hosts:$1|server0}/u/$1/$2"</pre>

    </dd>
  </dl>

  <p>See the <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>
  documentation for more discussion of the syntax of this directive.</p>

<div class="section">
<h2><a name="on-the-fly-content" id="on-the-fly-content">On-the-fly Content-Regeneration</a></h2>

  

  <dl>
    <dt>Description:</dt>

    <dd>
      <p>We wish to dynamically generate content, but store it
      statically once it is generated. This rule will check for the
      existence of the static file, and if it's not there, generate
      it. The static files can be removed periodically, if desired (say,
      via cron) and will be regenerated on demand.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      This is done via the following ruleset:

<pre class="prettyprint lang-config"># This example is valid in per-directory context only
RewriteCond "%{REQUEST_URI}"   "!-U"
RewriteRule "^(.+)\.html$"     "/regenerate_page.cgi"   [PT,L]</pre>


    <p>The <code>-U</code> operator determines whether the test string
    (in this case, <code>REQUEST_URI</code>) is a valid URL. It does
    this via a subrequest. In the event that this subrequest fails -
    that is, the requested resource doesn't exist - this rule invokes
    the CGI program <code>/regenerate_page.cgi</code>, which generates
    the requested resource and saves it into the document directory, so
    that the next time it is requested, a static copy can be served.</p>

    <p>In this way, documents that are infrequently updated can be served in
    static form. if documents need to be refreshed, they can be deleted
    from the document directory, and they will then be regenerated the
    next time they are requested.</p>

  <dl>
    <dt>Description:</dt>

    <dd>
      <p>We wish to randomly distribute load across several servers
      using mod_rewrite.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      <p>We'll use <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> and a list of servers
      to accomplish this.</p>

<pre class="prettyprint lang-config">RewriteEngine on
RewriteMap lb        "rnd:/path/to/serverlist.txt"
RewriteRule "^/(.*)" "http://${lb:servers}/$1"     [P,L]</pre>


<p><code>serverlist.txt</code> will contain a list of the servers:</p>

<div class="example"><p><code>
## serverlist.txt<br />
<br />
servers one.example.com|two.example.com|three.example.com<br />
</code></p></div>

<p>If you want one particular server to get more of the load than the
others, add it more times to the list.</p>

   </dd>

   <dt>Discussion</dt>
   <dd>
<p>Apache comes with a load-balancing module -
<code class="module"><a href="../mod/mod_proxy_balancer.html">mod_proxy_balancer</a></code> - which is far more flexible and
featureful than anything you can cobble together using mod_rewrite.</p>

    <dt>Description:</dt>

    <dd>
      <p>Some sites with thousands of users use a
      structured homedir layout, <em>i.e.</em> each homedir is in a
      subdirectory which begins (for instance) with the first
      character of the username. So, <code>/~larry/anypath</code>
      is <code>/home/<strong>l</strong>/larry/public_html/anypath</code>
      while <code>/~waldo/anypath</code> is
      <code>/home/<strong>w</strong>/waldo/public_html/anypath</code>.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      <p>We use the following ruleset to expand the tilde URLs

  <dl>

    <dd>
    <p>By default, redirecting to an HTML anchor doesn't work,
    because mod_rewrite escapes the <code>#</code> character,

    </dd>

    <dt>Solution:</dt>

      <p>We wish to use mod_rewrite to serve different content based on
      the time of day.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      <p>There are a lot of variables named <code>TIME_xxx</code>
      for rewrite conditions. In conjunction with the special
      lexicographic comparison patterns <code>&lt;STRING</code>,
      <code>&gt;STRING</code> and <code>=STRING</code> we can
      do time-dependent redirects:</p>

<pre class="prettyprint lang-config">RewriteEngine on
RewriteCond   "%{TIME_HOUR}%{TIME_MIN}" "&gt;0700"
RewriteCond   "%{TIME_HOUR}%{TIME_MIN}" "&lt;1900"
RewriteRule   "^foo\.html$"             "foo.day.html" [L]
RewriteRule   "^foo\.html$"             "foo.night.html"</pre>


      <p>This provides the content of <code>foo.day.html</code>
      under the URL <code>foo.html</code> from
      <code>07:01-18:59</code> and at the remaining time the
      contents of <code>foo.night.html</code>.</p>

      <div class="warning"><code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code>, intermediate proxies

      shown outside of the time-window configured.
      <code class="module"><a href="../mod/mod_expires.html">mod_expires</a></code> may be used to control this
      effect. You are, of course, much better off simply serving the
      content dynamically, and customizing it based on the time of day.</div>

  <dl>
    <dt>Description:</dt>

    <dd>
      <p>At times, we want to maintain some kind of status when we
      perform a rewrite. For example, you want to make a note that
      you've done that rewrite, so that you can check later to see if a
      request came via that rewrite. One way to do this is by setting an
      environment variable.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      <p>Use the [E] flag to set an environment variable.</p>

<pre class="prettyprint lang-config">RewriteEngine on
RewriteRule   "^/horse/(.*)"   "/pony/$1" [E=<strong>rewritten:1</strong>]</pre>


    <p>Later in your ruleset you might check for this environment
    variable using a RewriteCond:</p>

<pre class="prettyprint lang-config">RewriteCond "%{ENV:rewritten}" "=1"</pre>


    <p>Note that environment variables do not survive an external
    redirect. You might consider using the [CO] flag to set a
    cookie. For per-directory and htaccess rewrites, where the final
    substitution is processed as an internal redirect, environment
    variables from the previous round of rewriting are prefixed with
    "REDIRECT_". </p>

      <p>Assume we have recently renamed the page

      to provide the old URL for backward compatibility. However,
      we want that users of the old URL even not recognize that

    <p>In this example, as contrasted to the <a href="#old-to-new-intern">internal</a> example above, we can simply
    use the Redirect directive. mod_rewrite was used in that earlier
    example in order to hide the redirect from the client:</p>

    <dd>
    <p>This example uses an often-overlooked feature of mod_rewrite,
    by taking advantage of the order of execution of the ruleset. In
    particular, mod_rewrite evaluates the left-hand-side of the
    RewriteRule before it evaluates the RewriteCond directives.
    Consequently, $1 is already defined by the time the RewriteCond
    directives are evaluated. This allows us to test for the existence
    of the original (<code>document.html</code>) and target
    (<code>document.php</code>) files using the same base filename.</p>

    <p>This ruleset is designed to use in a per-directory context (In a
    &lt;Directory&gt; block or in a .htaccess file), so that the
    <code>-f</code> checks are looking at the correct directory path.
    You may need to set a <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> directive to specify the
    directory base that you're working in.</p>

        <dd>The goal of this rule is to force the use of a particular
        hostname, in preference to other hostnames which may be used to
        reach the same site. For example, if you wish to force the use
        of <strong>www.example.com</strong> instead of
        <strong>example.com</strong>, you might use a variant of the
        following recipe.</dd>

        <dt>Solution:</dt>

        <dd>

<p>The very best way to solve this doesn't involve mod_rewrite at all,
but rather uses the <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code>
directive placed in a virtual host for the non-canonical
hostname(s).</p>

<pre class="prettyprint lang-config">&lt;VirtualHost *:80&gt;
  ServerName undesired.example.com
  ServerAlias example.com notthis.example.com

  Redirect "/" "http://www.example.com/"
&lt;/VirtualHost&gt;

&lt;VirtualHost *:80&gt;
  ServerName www.example.com
&lt;/VirtualHost&gt;</pre>


<p>You can alternatively accomplish this using the
<code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code>
directive:</p>

<pre class="prettyprint lang-config">&lt;If "%{HTTP_HOST} != 'www.example.com'"&gt;
    Redirect "/" "http://www.example.com/"
&lt;/If&gt;</pre>


<p>Or, for example, to redirect a portion of your site to HTTPS, you
might do the following:</p>

<pre class="prettyprint lang-config">&lt;If "%{SERVER_PROTOCOL} != 'HTTPS'"&gt;
    Redirect "/admin/" "https://www.example.com/admin/"
&lt;/If&gt;</pre>


<p>If, for whatever reason, you still want to use <code>mod_rewrite</code>
- if, for example, you need this to work with a larger set of RewriteRules -
you might use one of the recipes below.</p>

<p>For sites running on a port other than 80:</p>
<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}"   "!^www\.example\.com" [NC]
RewriteCond "%{HTTP_HOST}"   "!^$"
RewriteCond "%{SERVER_PORT}" "!^80$"
RewriteRule "^/?(.*)"        "http://www.example.com:%{SERVER_PORT}/$1" [L,R,NE]</pre>


<p>And for a site running on port 80</p>
<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}"   "!^www\.example\.com" [NC]
RewriteCond "%{HTTP_HOST}"   "!^$"
RewriteRule "^/?(.*)"        "http://www.example.com/$1" [L,R,NE]</pre>


        <p>
        If you wanted to do this generically for all domain names - that
        is, if you want to redirect <strong>example.com</strong> to
        <strong>www.example.com</strong> for all possible values of
        <strong>example.com</strong>, you could use the following
        recipe:</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "!^www\." [NC]
RewriteCond "%{HTTP_HOST}" "!^$"
RewriteRule "^/?(.*)"      "http://www.%{HTTP_HOST}/$1" [L,R,NE]</pre>


    <p>These rulesets will work either in your main server configuration
    file, or in a <code>.htaccess</code> file placed in the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> of the server.</p>

<pre class="prettyprint lang-config">RedirectMatch "^/$" "http://example.com/about/"</pre>


<p>Note also that the example rewrites only the root URL. That is, it
rewrites a request for <code>http://example.com/</code>, but not a
request for <code>http://example.com/page.html</code>. If you have in
fact changed your document root - that is, if <strong>all</strong> of
your content is in fact in that subdirectory, it is greatly preferable
to simply change your <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>
directive, or move all of the content up one directory,
rather than rewriting URLs.</p>

<h2><a name="fallback-resource" id="fallback-resource">Fallback Resource</a></h2>


<dl>
<dt>Description:</dt>
<dd>You want a single resource (say, a certain file, like index.php) to
handle all requests that come to a particular directory, except those
that should go to an existing resource such as an image, or a css file.</dd>

<dt>Solution:</dt>
<dd>
<p>As of version 2.2.16, you should use the <code class="directive"><a href="../mod/mod_dir.html#fallbackresource">FallbackResource</a></code> directive for this:</p>

<pre class="prettyprint lang-config">&lt;Directory "/var/www/my_blog"&gt;
  FallbackResource "index.php"
&lt;/Directory&gt;</pre>


<p>However, in earlier versions of Apache, or if your needs are more
complicated than this, you can use a variation of the following rewrite
set to accomplish the same thing:</p>

<pre class="prettyprint lang-config">&lt;Directory "/var/www/my_blog"&gt;
  RewriteBase "/my_blog"

  RewriteCond "/var/www/my_blog/%{REQUEST_FILENAME}" !-f
  RewriteCond "/var/www/my_blog/%{REQUEST_FILENAME}" !-d
  RewriteRule "^" "index.php" [PT]
&lt;/Directory&gt;</pre>


<p>If, on the other hand, you wish to pass the requested URI as a query
string argument to index.php, you can replace that RewriteRule with:</p>

<pre class="prettyprint lang-config">RewriteRule "(.*)" "index.php?$1" [PT,QSA]</pre>


<p>Note that these rulesets can be used in a <code>.htaccess</code>
file, as well as in a &lt;Directory&gt; block.</p>

<h2><a name="rewrite-query" id="rewrite-query">Rewrite query string</a></h2>


<dl>
<dt>Description:</dt>
<dd>You want to capture a particular value from a query string
and either replace it or incorporate it into another component
of the URL.</dd>

<dt>Solutions:</dt>
<dd>
<p> Many of the solutions in this section will all use the same condition,
which leaves the matched value in the %2 backreference.  %1 is the beginining
of the query string (up to the key of intererest), and %3 is the remainder. This
condition is a bit complex for flexibility and to avoid double '&amp;&amp;' in the
substitutions.</p>
<ul>
  <li>This solution removes the matching key and value:

<pre class="prettyprint lang-config"># Remove mykey=???
RewriteCond "%{QUERY_STRING}" "(.*(?:^|&amp;))mykey=([^&amp;]*)&amp;?(.*)&amp;?$"
RewriteRule "(.*)" "$1?%1%3"</pre>

  </li>

  <li>This solution uses the captured value in the URL substitution,
  discarding the rest of the original query by appending a '?':

<pre class="prettyprint lang-config"># Copy from query string to PATH_INFO
RewriteCond "%{QUERY_STRING}" "(.*(?:^|&amp;))mykey=([^&amp;]*)&amp;?(.*)&amp;?$"
RewriteRule "(.*)" "$1/products/%2/?" [PT]</pre>

  </li>

  <li>This solution checks the captured value in a subsequent condition:

<pre class="prettyprint lang-config"># Capture the value of mykey in the query string
RewriteCond "%{QUERY_STRING}" "(.*(?:^|&amp;))mykey=([^&amp;]*)&amp;?(.*)&amp;?$"
RewriteCond "%2" !=not-so-secret-value 
RewriteRule "(.*)" - [F]</pre>

  </li>

  <li>This solution shows the reverse of the previous ones, copying
      path components (perhaps PATH_INFO) from the URL into the query string.
<pre class="prettyprint lang-config"># The desired URL might be /products/kitchen-sink, and the script expects
# /path?products=kitchen-sink.
RewriteRule "^/?path/([^/]+)/([^/]+)" "/path?$1=$2" [PT]</pre>

<h2><a name="InternalAPI" id="InternalAPI">API Phases</a></h2>

    <p>The Apache HTTP Server handles requests in several phases. At
    each of these phases, one or more modules may be called upon to
    handle that portion of the request lifecycle. Phases include things
    like URL-to-filename translation, authentication, authorization,
    content, and logging. (This is not an exhaustive list.)</p>

    <p>mod_rewrite acts in two of these phases (or "hooks", as they are
    often called) to influence how URLs may be rewritten.</p>

    <p>First, it uses the URL-to-filename translation hook, which occurs
    after the HTTP request has been read, but before any authorization
    starts. Secondly, it uses the Fixup hook, which is after the
    authorization phases, and after per-directory configuration files
    (<code>.htaccess</code> files) have been read, but before the
    content handler is called.</p>

    <p>So, after a request comes in and a corresponding server or
    virtual host has been determined, the rewriting engine starts
    processing any <code>mod_rewrite</code> directives appearing in the
    per-server configuration. (i.e., in the main server configuration file
    and <code class="directive"><a href="../mod/core.html#virtualhost">&lt;Virtualhost&gt;</a></code>
    sections.) This happens in the URL-to-filename phase.</p>

    <p>A few steps later, once the final data directories have been found,
    the per-directory configuration directives (<code>.htaccess</code>
    files and <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> blocks) are applied. This
    happens in the Fixup phase.</p>

    <p>In each of these cases, mod_rewrite rewrites the
    <code>REQUEST_URI</code> either to a new URL, or to a filename.</p>

    <p>In per-directory context (i.e., within <code>.htaccess</code> files
    and <code>Directory</code> blocks), these rules are being applied
    after a URL has already been translated to a filename. Because of
    this, the URL-path that mod_rewrite initially compares <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> directives against
    is the full filesystem path to the translated filename with the current
    directories path (including a trailing slash) removed from the front.</p>

    <p> To illustrate: If rules are in /var/www/foo/.htaccess and a request
    for /foo/bar/baz is being processed, an expression like ^bar/baz$ would
    match.</p>

    <p> If a substitution is made in per-directory context, a new internal 
    subrequest is issued with the new URL, which restarts processing of the 
    request phases. If the substitution is a relative path, the <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> directive 
    determines the URL-path prefix prepended to the substitution.
    In per-directory context, care must be taken to 
    create rules which will eventually (in some future "round" of per-directory
    rewrite processing) not perform a substitution to avoid looping.
    (See <a href="http://wiki.apache.org/httpd/RewriteLooping">RewriteLooping</a>
    for further discussion of this problem.)</p>

    <p>Because of this further manipulation of the URL in per-directory
    context, you'll need to take care to craft your rewrite rules
    differently in that context. In particular, remember that the
    leading directory path will be stripped off of the URL that your
    rewrite rules will see. Consider the examples below for further
    clarification.</p>

    <table class="bordered">

        <tr>
            <th>Location of rule</th>
            <th>Rule</th>
        </tr>

        <tr>
            <td>VirtualHost section</td>
            <td>RewriteRule "^/images/(.+)\.jpg" "/images/$1.gif"</td>
        </tr>

        <tr>
            <td>.htaccess file in document root</td>
            <td>RewriteRule "^images/(.+)\.jpg" "images/$1.gif"</td>
        </tr>

        <tr>
            <td>.htaccess file in images directory</td>
            <td>RewriteRule "^(.+)\.jpg" "$1.gif"</td>
        </tr>

    </table>

    <p>For even more insight into how mod_rewrite manipulates URLs in
    different contexts, you should consult the <a href="../mod/mod_rewrite.html#logging">log entries</a> made during 
    rewriting.</p>

<div class="section">
<h2><a name="InternalRuleset" id="InternalRuleset">Ruleset Processing</a></h2>

      <p>Now when mod_rewrite is triggered in these two API phases, it
      reads the configured rulesets from its configuration
      structure (which itself was either created on startup for
      per-server context or during the directory walk of the Apache
      kernel for per-directory context). Then the URL rewriting
      engine is started with the contained ruleset (one or more
      rules together with their conditions). The operation of the
      URL rewriting engine itself is exactly the same for both
      configuration contexts. Only the final result processing is
      different.</p>

      <p>The order of rules in the ruleset is important because the
      rewriting engine processes them in a special (and not very
      obvious) order. The rule is this: The rewriting engine loops
      through the ruleset rule by rule (<code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> directives) and
      when a particular rule matches it optionally loops through
      existing corresponding conditions (<code>RewriteCond</code>
      directives). For historical reasons the conditions are given
      first, and so the control flow is a little bit long-winded. See
      Figure 1 for more details.</p>
<p class="figure">
      <img src="../images/rewrite_process_uri.png" alt="Flow of RewriteRule and RewriteCond matching" /><br />
      <dfn>Figure 1:</dfn>The control flow through the rewriting ruleset
</p>
      <p>First the URL is matched against the
      <em>Pattern</em> of each rule. If it fails, mod_rewrite
      immediately stops processing this rule, and continues with the
      next rule. If the <em>Pattern</em> matches, mod_rewrite looks
      for corresponding rule conditions (RewriteCond directives,
      appearing immediately above the RewriteRule in the configuration).
      If none are present, it substitutes the URL with a new value, which is
      constructed from the string <em>Substitution</em>, and goes on
      with its rule-looping. But if conditions exist, it starts an
      inner loop for processing them in the order that they are
      listed. For conditions, the logic is different: we don't match
      a pattern against the current URL. Instead we first create a
      string <em>TestString</em> by expanding variables,
      back-references, map lookups, <em>etc.</em> and then we try
      to match <em>CondPattern</em> against it. If the pattern
      doesn't match, the complete set of conditions and the
      corresponding rule fails. If the pattern matches, then the
      next condition is processed until no more conditions are
      available. If all conditions match, processing is continued
      with the substitution of the URL with
      <em>Substitution</em>.</p>

<h2><a name="introduction" id="introduction">Introduction</a></h2>
    

   <p>
   The <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> directive
   defines an external function which can be called in the context of
   <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> or
   <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> directives to
   perform rewriting that is too complicated, or too specialized to be
   performed just by regular expressions. The source of this lookup can
   be any of the types listed in the sections below, and enumerated in
   the <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> reference
   documentation.</p>

   <p>The syntax of the <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>
   directive is as follows:</p>

<pre class="prettyprint lang-config">RewriteMap <em>MapName</em> <em>MapType</em>:<em>MapSource</em>
</pre>


    <p>The <a id="mapfunc" name="mapfunc"><em>MapName</em></a> is an
    arbitrary name that you assign to the map, and which you will use in
    directives later on. Arguments are passed to the map via the
    following syntax:</p>

    <p class="indent">
      <strong>
        <code>${</code> <em>MapName</em> <code>:</code> <em>LookupKey</em>
        <code>}</code> <br /> <code>${</code> <em>MapName</em> <code>:</code>
        <em>LookupKey</em> <code>|</code> <em>DefaultValue</em> <code>}</code>
      </strong>
    </p>

    <p>When such a construct occurs, the map <em>MapName</em> is
      consulted and the key <em>LookupKey</em> is looked-up. If the
      key is found, the map-function construct is substituted by
      <em>SubstValue</em>. If the key is not found then it is
      substituted by <em>DefaultValue</em> or by the empty string
      if no <em>DefaultValue</em> was specified.</p>

    <p>For example, you can define a
      <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> as:</p>
    <pre class="prettyprint lang-config">RewriteMap examplemap "txt:/path/to/file/map.txt"</pre>

    <p>You would then be able to use this map in a
      <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> as follows:</p>
      <pre class="prettyprint lang-config">RewriteRule "^/ex/(.*)" "${examplemap:$1}"</pre>


<p>A default value can be specified in the event that nothing is found
in the map:</p>

<pre class="prettyprint lang-config">RewriteRule "^/ex/(.*)" "${examplemap:$1|/not_found.html}"</pre>


<div class="note"><h3>Per-directory and .htaccess context</h3>
<p>
The <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> directive may not be
used in <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections or
<code>.htaccess</code> files. You must
declare the map in server or virtualhost context. You may use the map,
once created, in your <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> and
<code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> directives in those
scopes. You just can't <strong>declare</strong> it in those scopes.</p>
</div>

<p>The sections that follow describe the various <em>MapType</em>s that
may be used, and give examples of each.</p>
  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="int" id="int">int: Internal Function</a></h2>
    

    <p>When a MapType of <code>int</code> is used, the MapSource is one
    of the available internal <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>
    functions.  Module authors can provide
    additional internal functions by registering them with the
    <code>ap_register_rewrite_mapfunc</code> API.
    The functions that are provided by default are:
    </p>

    <ul>
      <li><strong>toupper</strong>:<br />
             Converts the key to all upper case.</li>
      <li><strong>tolower</strong>:<br />
             Converts the key to all lower case.</li>
      <li><strong>escape</strong>:<br />
             Translates special characters in the key to
            hex-encodings.</li>
      <li><strong>unescape</strong>:<br />
             Translates hex-encodings in the key back to
            special characters.</li>
    </ul>

    <p>
    To use one of these functions, create a <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> referencing
    the int function, and then use that in your <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>:
    </p>

   <p> <strong>Redirect a URI to an all-lowercase version of itself</strong></p>
    <pre class="prettyprint lang-config">RewriteMap lc int:tolower
RewriteRule "(.*)" "${lc:$1}" [R]</pre>


    <div class="note">
    <p>Please note that the example offered here is for
    illustration purposes only, and is not a recommendation. If you want
    to make URLs case-insensitive, consider using
    <code class="module"><a href="../mod/mod_speling.html">mod_speling</a></code> instead.
    </p>
    </div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="txt" id="txt">txt: Plain text maps</a></h2>
    

    <p>When a MapType of <code>txt</code> is used, the MapSource is a filesystem path to a
    plain-text mapping file, containing one space-separated key/value pair
    per line. Optionally, a line may contain a comment, starting with
    a '#' character.</p>

    <p>A valid text rewrite map file will have the following syntax:</p>

    <div class="example"><p><code>
      # Comment line<br />
      <strong><em>MatchingKey</em> <em>SubstValue</em></strong><br />
      <strong><em>MatchingKey</em> <em>SubstValue</em></strong> # comment<br />
    </code></p></div>

    <p>When the <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> is invoked
    the argument is looked for in the
    first argument of a line, and, if found, the substitution value is
    returned.</p>

    <p>For example, we can use a mapfile to translate product names to
    product IDs for easier-to-remember URLs, using the following
    recipe:</p>
<p><strong>Product to ID configuration</strong></p>
    <pre class="prettyprint lang-config">RewriteMap product2id "txt:/etc/apache2/productmap.txt"
RewriteRule "^/product/(.*)" "/prods.php?id=${product2id:$1|NOTFOUND}" [PT]</pre>


    <p>We assume here that the <code>prods.php</code> script knows what
    to do when it received an argument of <code>id=NOTFOUND</code> when
    a product is not found in the lookup map.</p>

    <p>The file <code>/etc/apache2/productmap.txt</code> then contains
    the following:</p>

    <div class="example"><h3>Product to ID map</h3><p><code>
##<br />
##  productmap.txt - Product to ID map file<br />
##<br />
<br />
television 993<br />
stereo     198<br />
fishingrod 043<br />
basketball 418<br />
telephone  328
    </code></p></div>

    <p>Thus, when <code>http://example.com/product/television</code> is
    requested, the <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> is
    applied, and the request
    is internally mapped to <code>/prods.php?id=993</code>.</p>

    <div class="note"><h3>Note: .htaccess files</h3>
    The example given is crafted to be used in server or virtualhost
    scope. If you're planning to use this in a <code>.htaccess</code>
    file, you'll need to remove the leading slash from the rewrite
    pattern in order for it to match anything:
    <pre class="prettyprint lang-config">RewriteRule "^product/(.*)" "/prods.php?id=${product2id:$1|NOTFOUND}" [PT]</pre>

    </div>

    <div class="note"><h3>Cached lookups</h3>
    <p>
    The looked-up keys are cached by httpd until the <code>mtime</code>
    (modified time) of the mapfile changes, or the httpd server is
    restarted. This ensures better performance on maps that are called
    by many requests.
    </p>
    </div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="rnd" id="rnd">rnd: Randomized Plain Text</a></h2>
    

    <p>When a MapType of <code>rnd</code> is used, the MapSource is a
    filesystem path to a plain-text mapping file, each line of which
    contains a key, and one or more values separated by <code>|</code>.
    One of these values will be chosen at random if the key is
    matched.</p>

    <p>For example, you can use the following map
    file and directives to provide a random load balancing between
    several back-end servers, via a reverse-proxy. Images are sent
    to one of the servers in the 'static' pool, while everything
    else is sent to one of the 'dynamic' pool.</p>

    <div class="example"><h3>Rewrite map file</h3><p><code>
##<br />
##  map.txt -- rewriting map<br />
##<br />
<br />
static   www1|www2|www3|www4<br />
dynamic  www5|www6
    </code></p></div>
<p><strong>Configuration directives</strong></p>
    <pre class="prettyprint lang-config">RewriteMap servers "rnd:/path/to/file/map.txt"

RewriteRule "^/(.*\.(png|gif|jpg))" "http://${servers:static}/$1"  [NC,P,L]
RewriteRule "^/(.*)"                "http://${servers:dynamic}/$1" [P,L]</pre>


    <p>So, when an image is requested and the first of these rules is
    matched, <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> looks up the string
    <code>static</code> in the map file, which returns one of the
    specified hostnames at random, which is then used in the
    <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> target.</p>

    <p>If you wanted to have one of the servers more likely to be chosen
    (for example, if one of the server has more memory than the others,
    and so can handle more requests) simply list it more times in the
    map file.</p>

    <div class="example"><p><code>
static   www1|www1|www2|www3|www4
    </code></p></div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="dbm" id="dbm">dbm: DBM Hash File</a></h2>
    

    <p>When a MapType of <code>dbm</code> is used, the MapSource is a
    filesystem path to a DBM database file containing key/value pairs to
    be used in the mapping. This works exactly the same way as the
    <code>txt</code> map, but is much faster, because a DBM is indexed,
    whereas a text file is not. This allows more rapid access to the
    desired key.</p>

    <p>You may optionally specify a particular dbm type:</p>

 <pre class="prettyprint lang-config">RewriteMap examplemap "dbm=sdbm:/etc/apache/mapfile.dbm"</pre>


    <p>The type can be <code>sdbm</code>, <code>gdbm</code>, <code>ndbm</code> 
    or <code>db</code>.
    However, it is recommended that you just use the <a href="../programs/httxt2dbm.html">httxt2dbm</a> utility that is
    provided with Apache HTTP Server, as it will use the correct DBM library,
    matching the one that was used when httpd itself was built.</p>

    <p>To create a dbm file, first create a text map file as described
    in the <a href="#txt">txt</a> section. Then run
    <code>httxt2dbm</code>:</p>

<div class="example"><p><code>
$ httxt2dbm -i mapfile.txt -o mapfile.map
</code></p></div>

<p>You can then reference the resulting file in your
<code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> directive:</p>

<pre class="prettyprint lang-config">RewriteMap mapname "dbm:/etc/apache/mapfile.map"</pre>


<div class="note">
<p>Note that with some dbm types, more than one file is generated, with
a common base name. For example, you may have two files named
<code>mapfile.map.dir</code> and <code>mapfile.map.pag</code>. This is
normal, and you need only use the base name <code>mapfile.map</code> in
your <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> directive.</p>
</div>

<div class="note"><h3>Cached lookups</h3>
<p>
The looked-up keys are cached by httpd until the <code>mtime</code>
(modified time) of the mapfile changes, or the httpd server is
restarted. This ensures better performance on maps that are called
by many requests.

<h2><a name="prg" id="prg">prg: External Rewriting Program</a></h2>

    <p>When a MapType of <code>prg</code> is used, the MapSource is a
    filesystem path to an executable program which will providing the
    mapping behavior. This can be a compiled binary file, or a program
    in an interpreted language such as Perl or Python.</p>

    <p>This program is started once, when the Apache HTTP Server is
    started, and then communicates with the rewriting engine via
    <code>STDIN</code> and <code>STDOUT</code>. That is, for each map
    function lookup, it expects one argument via <code>STDIN</code>, and
    should return one new-line terminated response string on
    <code>STDOUT</code>. If there is no corresponding lookup value, the
    map program should return the four-character string
    "<code>NULL</code>" to indicate this.</p>

    <p>External rewriting programs are not started if they're defined in
    a context that does not have <code class="directive"><a href="../mod/mod_rewrite.html#rewriteengine">RewriteEngine</a></code> set to
    <code>on</code>.</p>

    <p>By default, external rewriting programs are run as the
    user:group who started httpd. This can be changed on UNIX systems
    by passing user name and group name as third argument to
    <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> in the
    <code>username:groupname</code> format.</p>

    <p>This feature utilizes the <code>rewrite-map</code> mutex,
    which is required for reliable communication with the program.
    The mutex mechanism and lock file can be configured with the
    <code class="directive"><a href="../mod/core.html#mutex">Mutex</a></code> directive.</p>

    <p>A simple example is shown here which will replace all dashes with
    underscores in a request URI.</p>

    <p><strong>Rewrite configuration</strong></p>
    <pre class="prettyprint lang-config">RewriteMap d2u "prg:/www/bin/dash2under.pl" apache:apache
RewriteRule "-" "${d2u:%{REQUEST_URI}}"</pre>


    <p><strong>dash2under.pl</strong></p>
    <pre class="prettyprint lang-perl">#!/usr/bin/perl
$| = 1; # Turn off I/O buffering
while (&lt;STDIN&gt;) {
    s/-/_/g; # Replace dashes with underscores
    print $_;
}</pre>


<div class="note"><h3>Caution!</h3>
<ul>
<li>Keep your rewrite map program as simple as possible. If the program
hangs, it will cause httpd to wait indefinitely for a response from the
map, which will, in turn, cause httpd to stop responding to
requests.</li>
<li>Be sure to turn off buffering in your program. In Perl this is done
by the second line in the example script: <code>$| = 1;</code> This will
of course vary in other languages. Buffered I/O will cause httpd to wait
for the output, and so it will hang.</li>
<li>Remember that there is only one copy of the program, started at
server startup. All requests will need to go through this one bottleneck.
This can cause significant slowdowns if many requests must go through
this process, or if the script itself is very slow.</li>
</ul>

<h2><a name="dbd" id="dbd">dbd or fastdbd: SQL Query</a></h2>
    

    <p>When a MapType of <code>dbd</code> or <code>fastdbd</code> is
    used, the MapSource is a SQL SELECT statement that takes a single
    argument and returns a single value.</p>

    <p><code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> will need to be configured to point at
    the right database for this statement to be executed.</p>

    <p>There are two forms of this MapType.
    Using a MapType of <code>dbd</code> causes the query to be
    executed with each map request, while using <code>fastdbd</code>
    caches the database lookups internally. So, while
    <code>fastdbd</code> is more efficient, and therefore faster, it
    won't pick up on changes to the database until the server is
    restarted.</p>

    <p>If a query returns more than one row, a random row from
    the result set is used.</p>

    <div class="example"><h3>Example</h3><pre class="prettyprint lang-config">RewriteMap myquery "fastdbd:SELECT destination FROM rewrite WHERE source = %s"</pre>
</div>

    <div class="note"><h3>Note</h3>
    <p>The query name is passed to the database driver as a label for
    an SQL prepared statement, and will therefore need to follow any rules
    (such as case-sensitivity) required for your database.</p></div>

<a href="../mod/mod_rewrite.html">reference documentation</a>. It describes
how to use the RewriteRule's [P] flag to proxy content to another server.
A number of recipes are provided that describe common scenarios.</p>

<h2><a name="dynamic-proxy" id="dynamic-proxy">Proxying Content with mod_rewrite</a></h2>

  

  <dl>
    <dt>Description:</dt>

    <dd>
    <p>
    mod_rewrite provides the [P] flag, which allows URLs to be passed,
    via mod_proxy, to another server. Two examples are given here. In
    one example, a URL is passed directly to another server, and served
    as though it were a local URL. In the other example, we proxy
    missing content to a back-end server.</p>
    </dd>

    <dt>Solution:</dt>

    <dd>
      <p>To simply map a URL to another server, we use the [P] flag, as
      follows:</p>

<pre class="prettyprint lang-config">RewriteEngine  on
RewriteBase    "/products/"
RewriteRule    "^widget/(.*)$"  "http://product.example.com/widget/$1"  [P]
ProxyPassReverse "/products/widget/" "http://product.example.com/widget/"</pre>


   <p>In the second example, we proxy the request only if we can't find
   the resource locally. This can be very useful when you're migrating
   from one server to another, and you're not sure if all the content
   has been migrated yet.</p>

<pre class="prettyprint lang-config">RewriteCond "%{REQUEST_FILENAME}"       !-f
RewriteCond "%{REQUEST_FILENAME}"       !-d
RewriteRule "^/(.*)" "http://old.example.com/$1" [P]
ProxyPassReverse "/" "http://old.example.com/"</pre>

    </dd>

    <dt>Discussion:</dt>

    <dd><p>In each case, we add a <code class="directive"><a href="../mod/mod_proxy.html#proxypassreverse">ProxyPassReverse</a></code> directive to ensure
    that any redirects issued by the backend are correctly passed on to
    the client.</p>

    <p>Consider using either <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> or <code class="directive"><a href="../mod/mod_proxy.html#proxypassmatch">ProxyPassMatch</a></code> whenever possible in
    preference to mod_rewrite.</p>

<p>Ce document est un complément à la <a href="../mod/mod_rewrite.html">Documentation de référence</a> de
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>. Il décrit peut-être un des concepts les
plus importants à propos de <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> - à savoir, quand doit-on éviter
de l'utiliser.</p>

<p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> doit être considéré comme un dernier recours,
lorsqu'aucune alternative n'est possible. Utiliser mod_rewrite lorsqu'il
existe des alternatives plus simples conduit à des configurations
confuses, fragiles, et difficiles à maintenir. La compréhension des
autres alternatives disponibles est une étape très importante sur le
chemin de la maîtrise de <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>.</p>

<p>Vous devez vous attacher à comprendre le
fonctionnement des exemples, car la plupart d'entre eux ne
fonctionneront pas sur votre système si vous vous contentez de les
copier/coller dans vos fichiers de configuration.</p>

<p>Le cas le plus courant dans lequel <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> est
l'outil approprié est la situation où la seule solution envisageable
nécessite l'accès aux fichiers de configuration du serveur, alors que
cet accès ne vous est pas accordé. Certaines directives de configuration
ne sont disponibles que dans le fichier de configuration du serveur. Si
vous ne pouvez agir que sur les fichiers .htaccess, vous devrez donc
vous tourner vers <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>.</p>

<h2><a name="redirect" id="redirect">Redirection simple</a></h2>


<p><code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> fournit les directives <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code> et <code class="directive"><a href="../mod/mod_alias.html#redirectmatch">RedirectMatch</a></code> qui permettent de
rediriger une URL vers une autre. Plutôt que d'utiliser la directive
<code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> pour ce genre de
redirection simple d'une URL ou d'une classe d'URLs vers une autre, on
préfèrera l'utilisation de ces directives. En outre, avec
<code>RedirectMatch</code>, vous pouvez inclure une expression
rationnelle dans votre critère de redirection, ce qui vous permet de
bénéficier de nombreux avantages de la directive
<code>RewriteRule</code>.</p>

<p>Une utilisation courante de la directive <code>RewriteRule</code> est
la redirection de toute une classe d'URLs. Par exemple, toutes les URLs
faisant référence au répertoire <code>/un</code> doivent être
redirigées vers <code>http://un.example.com/</code>, ou toutes les
requêtes <code>http</code> doivent être redirigées vers
<code>https</code>.</p>

<p>Pour ce faire, il est préférable d'utiliser la directive
<code>Redirect</code>. Souvenez-vous que la directive
<code>Redirect</code> conserve les informations relatives au chemin. En
d'autres termes, la redirection d'une URL <code>/un</code> va aussi
rediriger toutes les URLs de niveaux inférieurs comme
<code>/un/deux.html</code> et <code>/un/trois/quatre.html</code>.</p>

<p>Pour rediriger les URLs sous <code>/un</code> vers
<code>http://un.example.com/</code>, utilisez cette définition :</p>

<pre class="prettyprint lang-config">Redirect /one/ http://one.example.com/</pre>


<p>Pour rediriger un nom d'hôte vers un autre nom d'hôte, par exemple
<code>example.com</code> vers <code>www.example.com</code>, voir la
méthode <a href="remapping.html#canonicalhost">Noms d'hôtes canoniques</a>.</p>

<p>Pour rediriger les URLs <code>http</code> vers <code>https</code>,
utilisez cette définition :</p>

<pre class="prettyprint lang-config">&lt;VirtualHost *:80&gt;
ServerName www.example.com
Redirect "/" "https://www.example.com/"
&lt;/VirtualHost&gt;

&lt;VirtualHost *:443&gt;
ServerName www.example.com
#  ... insérer ici la configuration SSL
&lt;/VirtualHost&gt;</pre>


<p>L'utilisation de la directive <code>RewriteRule</code> pour accomplir
cette tâche peut se justifier s'il existe d'autres directives
<code>RewriteRule</code> dans la même portée. En effet, lorsque des
directives <code>Redirect</code> et <code>RewriteRule</code> se trouvent
dans la même portée, les directives <code>RewriteRule</code> sont
exécutées en premier, sans tenir compte de leur ordre d'apparition dans
le fichier de configuration.</p>

<p>Dans le cas de la redirection <em>http-vers-https</em>, l'utilisation
de règles <code>RewriteRule</code> se justifie si vous n'avez pas accès
au fichier de configuration principal, et devez donc accomplir cette
tâche au sein d'un fichier <code>.htaccess</code>.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="alias" id="alias">Alias d'URL</a></h2>
<p>La directive <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> permet
de mettre en correspondance un URI avec un répertoire, ce dernier étant
en général situé en dehors de l'arborescence définie par la directive
<code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>. Bien qu'il soit
possible d'effectuer cette mise en correspondance avec
<code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>, il est préférable d'utiliser la directive
<code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> pour des raisons de simplicité
et de performances.</p>

<div class="example"><h3>Utilisation de la directive Alias</h3><pre class="prettyprint lang-config">Alias "/cats" "/var/www/virtualhosts/felines/htdocs"</pre>
</div>

<p>
Pour effectuer cette mise en correspondance, <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>
s'impose si vous n'avez pas accès aux fichiers de configuration du
serveur. En effet, la directive Alias ne peut pas être utilisée dans un
fichier <code>.htaccess</code>, mais seulement dans un contexte de
serveur principal ou de serveur virtuel.
</p>

<p>En outre, vous pouvez arriver au même résultat avec les liens
symboliques, pourvu que <code>Options FollowSymLinks</code> soit activé
sur votre serveur.</p>

<div class="section">
<h2><a name="vhosts" id="vhosts">Hébergement virtuel</a></h2>
<p>Bien qu'il soit possible de gérer les <a href="vhosts.html">serveurs
virtuels avec mod_rewrite</a>, il s'agit rarement de la bonne méthode.
Il est pratiquement toujours préférable de créer des blocs
<code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code> individuels.
Dans l'éventualité où vous devez gérer
un grand nombre de serveurs virtuels, vous devez vous tourner vers
<code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code> pour créer ces serveurs
automatiquement.</p>

<p>Il est aussi possible d'utiliser des modules comme <code class="module"><a href="../mod/mod_macro.html">mod_macro</a></code> pour
créer un grand nombre de serveurs virtuels dynamiquement.</p>

<p>L'utilisation de <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> pour la création de
serveurs virtuels peut se révéler appropriée si votre service
d'hébergement ne vous permet pas d'accéder aux fichiers de configuration
du serveur, et que vous soyez par conséquent obligé de passer par les
fichiers <code>.htaccess</code>.</p>

<p>Voir le document <a href="vhosts.html">création de serveurs virtuels
avec mod_rewrite</a> pour plus de détails sur la manière d'y parvenir si
cela semble être tout de même la meilleure approche.</p>

<div class="section">
<h2><a name="proxy" id="proxy">Mandat simple</a></h2>

<p>La directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> fournit
le drapeau <a href="flags.html#flag_p">[P]</a> qui permet de faire passer les URIs
réécrits par <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>.</p>

<pre class="prettyprint lang-config">RewriteRule "^/?images(.*)" "http://serveur-images.local/images$1" [P]</pre>


<p>Cependant, dans les nombreux cas où aucune correspondance au modèle
n'est vraiment nécessaire, comme dans l'exemple ci-dessus, il est
préférable d'utiliser la directive <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>. L'exemple précédent pourrait
être remplacé par :</p>

<pre class="prettyprint lang-config">ProxyPass "/images/" "http://serveur-images.local/images/"</pre>


<p>Que vous utilisiez <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> ou <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>, vous devrez dans tous les cas
utiliser aussi la directive <code class="directive"><a href="../mod/mod_proxy.html#proxypassreverse">ProxyPassReverse</a></code> pour intercepter les
redirections en provenance du serveur d'arrière-plan :</p>

<pre class="prettyprint lang-config">ProxyPassReverse "/images/" "http://serveur-images.local/images/"</pre>


<p>Vous devrez cependant tout de même utiliser <code>RewriteRule</code>
lorsque d'autres <code>RewriteRule</code>s se trouvent dans la même portée,
car elles agissent en général avant les directives
<code>ProxyPass</code>, et peuvent ainsi les court-circuiter.</p>

<div class="section">
<h2><a name="setenv" id="setenv">Test de variables d'environnement</a></h2>

<p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> est souvent utilisé pour effectuer une
action en fonction de la présence ou de l'absence d'une variable
d'environnement particulière ou d'un en-tête de requête, ce qui peut
être accompli de manière plus efficace via la directive <code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code>.</p>

<p>Considérons par exemple le scénario courant où la directive
<code class="directive">RewriteRule</code> est utilisée pour forcer un nom
d'hôte canonique, tel que <code>www.example.com</code> au lieu de
<code>example.com</code>. Il est possible d'utiliser à la place la
directive <code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code> comme
suit :</p>

<pre class="prettyprint lang-config">&lt;If "req('Host') != 'www.example.com'"&gt;
    Redirect "/" "http://www.example.com"
&lt;/If&gt;</pre>


<p>On peut utiliser cette technique dans de nombreux scénarios courant
pour remplacer <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> pour effectuer des actions
en fonction d'en-têtes de requêtes ou de réponses, ou de variables
d'environnement.</p>

<p>Voir en particulier la <a href="../expr.html">documentation sur
l'évaluation des expressions</a> pour une vue d'ensemble des types
d'expressions que vous pouvez utiliser dans les sections <code class="directive"><a href="../mod/core.html#if">&lt;If&gt;</a></code>,

<h2><a name="dynamic-proxy" id="dynamic-proxy">Mandater du contenu avec mod_rewrite</a></h2>

  

  <dl>
    <dt>Description :</dt>

    <dd>
    <p>
    mod_rewrite implémente le drapeau [P] qui permet de passer des URLs,
    via mod_proxy, à un autre serveur. Deux exemples sont fournis ici.
    Dans le premier, une URL est passée directement à un autre serveur,
    et servie comme si c'était une URL locale. Dans le deuxième, nous
    mandatons un contenu manquant vers un serveur d'arrière-plan.</p>
    </dd>

    <dt>Solution :</dt>

    <dd>
      <p>Pour passer une URL à un autre serveur, on utilise le drapeau
      [P] comme suit :</p>

<pre class="prettyprint lang-config">RewriteEngine  on
RewriteBase    "/produits/"
RewriteRule    "^widget/(.*)$"  "http://produits.example.com/widget/$1"  [P]
ProxyPassReverse "/produits/objet/" "http://produits.example.com/objet/"</pre>


   <p>Dans le deuxième exemple, nous ne mandatons la requête que si nous
   ne trouvons pas la ressource localement. Ceci peut s'avérer très
   utile lorsque vous effectuez une migration d'un serveur vers un
   autre, et que vous n'êtes pas certain que tout le contenu a déjà été
   migré.</p>

<pre class="prettyprint lang-config">RewriteCond "%{REQUEST_FILENAME}"       !-f
RewriteCond "%{REQUEST_FILENAME}"       !-d
RewriteRule "^/(.*)" "http://ancien.exemple.com/$1" [P]
ProxyPassReverse "/" "http://ancien.exemple.com/"</pre>

    </dd>

    <dt>Discussion :</dt>

    <dd><p>Dans les deux cas, on ajoute une directive <code class="directive"><a href="../mod/mod_proxy.html#proxypassreverse">ProxyPassReverse</a></code> afin de s'assurer
    que toute redirection en provenance du serveur d'arrière-plan est
    renvoyée correctement au client.</p>

    <p>Chaque fois que cela est possible, préférez l'utilisation de la
    directive <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> ou
    <code class="directive"><a href="../mod/mod_proxy.html#proxypassmatch">ProxyPassMatch</a></code> à
    mod_rewrite.</p>

<h2><a name="blocked-inline-images" id="blocked-inline-images">Blocage du référencement à chaud (Hotlinking) d'images</a></h2>

      

      <dl>
        <dt>Description :</dt>

        <dd>
          <p>Cette technique vous permet d'interdire à d'autres sites
	  d'inclure directement vos images dans leurs pages. On fait
	  souvent référence à cette pratique sous le nom de
	  référencement à chaud (Hotlinking) qui entraîne l'utilisation
	  de votre bande passante pour servir des contenus faisant
	  partie du site de quelqu'un d'autre.</p>
        </dd>

        <dt>Solution :</dt>

        <dd>
	<p>Cette technique repose sur la valeur de la variable
	optionnelle <code>HTTP_REFERER</code>. Certaines personnes
	pourront donc contourner cette limitation. Pour la plupart des
	utilisateurs cependant, la requête échouera, en ce sens que
	l'image ne sera pas affichée depuis le site tiers.</p>
	<p>Il y a plusieurs manières de gérer cette situation.</p>

	<p>Dans le premier exemple, nous rejetons tout simplement la
	requête si elle ne provenait pas d'une page appartenant à notre
	site. Pour les besoins de cet exemple, nous supposons que le nom
	de votre site est <code>www.example.com</code>.</p>



<pre class="prettyprint lang-config">RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule "\.(gif|jpg|png)$"    "-"   [F,NC]</pre>


	<p>Dans le second exemple, plutôt que de rejeter la requête,
	nous affichons une autre image à la place.</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule "\.(gif|jpg|png)$"    "/images/go-away.png"   [R,NC]</pre>


	<p>Dans le troisième exemple, nous redirigeons la requête vers
	une image appartenant à un autre site.</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_REFERER}" "!^$"
RewriteCond "%{HTTP_REFERER}" "!www.example.com" [NC]
RewriteRule "\.(gif|jpg|png)$" "http://other.example.com/image.gif"   [R,NC]</pre>


	<p>De tous ces exemples, les deux derniers semblent les plus
	efficaces pour faire en sorte que les gens arrêtent de
	référencer vos images à chaud, car il ne verront pas les images
	qu'ils s'attendent à voir.</p>

        </dd>

        <dt>Discussion :</dt>

        <dd>
        <p>Si vous ne voulez pas rediriger la requête, mais

        <dt>Description :</dt>

        <dd>
        <p>
        Dans cet exemple, nous allons discuter d'une méthode permettant
	de bloquer les requêtes persistentes en provenance d'un robot
	particulier, ou d'un navigateur.</p>

        <p>La méthode classique pour exclure un robot consiste à définir
	un fichier, <code>/robots.txt</code> qui spécifie les parties de
	votre site web pour lesquelles vous voulez exclure les robots.
	Malheureusement, certains robots ne tiennent pas compte de ces
	fichiers.
        </p>

        <p>Notez qu'il existe des méthodes d'exclusion qui n'utilisent
	pas mod_rewrite. Notez aussi que toute technique qui repose sur
	le contenu de la chaîne client <code>USER_AGENT</code> peut être
	contournée très facilement car cette chaîne peut être modifiée.</p>
        </dd>

        <dt>Solution :</dt>

        <dd>
        <p>On utilise un jeu de règles qui spécifie le répertoire à
	protéger, ainsi que la chaîne client <code>USER_AGENT</code> qui
	identifie le robot malin ou envahissant.</p>

        <p>Dans cet exemple, nous bloquons un robot nommé
	<code>Vilain_Robot</code> pour le répertoire
	<code>/secret/fichiers</code>. Si vous voulez bloquer ce client
	seulement depuis une source particulière, vous pouvez aussi
	spécifier un intervalle d'adresses IP.</p>

<pre class="prettyprint lang-config">RewriteCond "%{HTTP_USER_AGENT}"   "^NameOfBadRobot"
RewriteCond "%{REMOTE_ADDR}"       "=123\.45\.67\.[8-9]"
RewriteRule "^/secret/files/"   "-"   [F]</pre>

        </dd>

      <dt>Discussion :</dt>

      <dd>
      <p>
        Vous pouvez cependant parvenir au même résultat sans utiliser
	mod_rewrite via la méthode alternative suivante :
      </p>
      <pre class="prettyprint lang-config">SetEnvIfNoCase User-Agent "^NameOfBadRobot" goaway
&lt;Location "/secret/files"&gt;
    &lt;RequireAll&gt;
        Require all granted
        Require not env goaway
    &lt;/RequireAll&gt;
&lt;/Location&gt;</pre>

      <p>
      Comme indiqué plus haut, il est aisé de contourner cette
      technique, simplement en modifiant le contenu de l'en-tête
      <code>USER_AGENT</code>. Si vous subissez une attaque en règle,
      vous allez devoir réfléchir à un blocage à un niveau supérieur,
      par exemple une règle de filtrage de votre pare-feu.

   <p>
   La directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>
   définit une fonction externe qui peut être appelée depuis une
   directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> ou
   <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> pour
   accomplir une réécriture trop compliquée, ou trop spécialisée pour
   être effectuée à partir d'expressions rationnelles. Vous trouverez
   ci-dessous les différents types disponibles pour la source de
   données, ceux-ci étant par ailleurs énumérés dans la documentation de
   référence de <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>.</p>

   <p>La syntaxe de la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> est la suivante
   :</p>

<pre class="prettyprint lang-config">RewriteMap <em>MapName</em> <em>MapType</em>:<em>MapSource</em></pre>


    <p>L'argument <a id="mapfunc" name="mapfunc"><em>MapName</em></a>
    est un nom arbitraire que vous associez à la table de
    correspondances, et que vous
    pourrez utilisez par la suite dans les directives de réécriture. Les
    recherches dans la table de correspondance s'effectuent en
    respectant cette syntaxe :</p>

    <p class="indent">
      <strong>
        <code>${</code> <em>nom-map</em> <code>:</code>
	<em>clé-recherche</em>
        <code>}</code> <br /> <code>${</code> <em>nom-map</em> <code>:</code>
        <em>clé-recherche</em> <code>|</code> <em>DefaultValue</em> <code>}</code>
      </strong>
    </p>

    <p>Lorsque cette syntaxe est employée, la table de correspondances
    <em>nom-map</em> est consultée et la clé <em>clé-recherche</em>
    recherchée. Si la clé est trouvée, la fonction de recherche dans la
    table de correspondance est remplacée par <em>SubstValue</em>, ou
    par <em>DefaultValue</em> dans le cas contraire, ou par la chaîne
    vide si aucune <em>DefaultValue</em> n'a été spécifiée.</p>

    <p>Par exemple, vous pouvez définir une directive
    <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> comme suit :</p>
    <pre class="prettyprint lang-config">RewriteMap examplemap "txt:/path/to/file/map.txt"</pre>

    <p>Vous pourrez par la suite utiliser cette table de correspondances
    dans une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> comme suit :</p>
<pre class="prettyprint lang-config">RewriteRule "^/ex/(.*)" "${examplemap:$1}"</pre>


<p>Il est possible de spécifier une valeur par défaut qui sera utilisée
si la recherche dans la table de correspondances est infructueuse :</p>

<pre class="prettyprint lang-config">RewriteRule "^/ex/(.*)" "${examplemap:$1|/not_found.html}"</pre>


<div class="note"><h3>Contexte de répertoire et fichiers.htaccess</h3>
<p>
Vous ne pouvez utiliser la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> ni dans
les sections <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>, ni dans les fichiers
<code>.htaccess</code>. Vous devez déclarer la table de correspondances
au niveau du serveur principal ou dans un contexte de serveur virtuel.
En revanche, si vous ne pouvez pas déclarer la table dans une section
&lt;Directory&gt; ou dans un fichier <code>.htaccess</code>, vous
pourrez y faire référence dans ces contextes, une fois cette table
créée.
</p>
</div>

<p>Les sections suivantes décrivent les différents types de tables de
correspondances <em>type-map</em> disponibles, et fournissent des
exemples pour chacun d'entre eux.</p>
  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="int" id="int">int: Fonction interne</a></h2>
    

    <p>Lorsque le type-map <code>int</code> est spécifié, la source est
    une des fonctions RewriteMap internes disponibles. Les développeurs
    de modules peuvent fournir des fonctions internes supplémentaires en
    les enregistrant via l'API <code>ap_register_rewrite_mapfunc</code>.
    Les fonctions fournies par défaut sont :
    </p>

    <ul>
      <li><strong>toupper</strong>:<br />
             Met tous les caractères de la clé en majuscules.</li>
      <li><strong>tolower</strong>:<br />
             Met tous les caractères de la clé en minuscules.</li>
      <li><strong>escape</strong>:<br />
             Protège les caractères spéciaux de la clé en les
	     transformant en leur code hexadécimal.</li>
      <li><strong>unescape</strong>:<br />
             Retraduit les codes hexadécimaux de la clé en caractères
	     spéciaux.</li>
    </ul>

    <p>
    Pour utiliser une de ces fonctions, créez une
    <code>RewriteMap</code> faisant référence à cette fonction int, et
    utilisez-la dans votre règle <code>RewriteRule</code> :
    </p>

    <p> <strong>Redirige un URI vers son équivalent en minuscules</strong></p>
    <pre class="prettyprint lang-config">RewriteMap lc int:tolower
RewriteRule "(.*)" "${lc:$1}" [R]</pre>


    <div class="note">
    <p>Notez que cet exemple n'est fourni qu'à titre d'illustration,
    et ne constitue en aucun cas une recommandation. Si vous voulez
    rendre des URLs insensibles à la casse, vous devez plutôt vous
    tourner vers <code class="module"><a href="../mod/mod_speling.html">mod_speling</a></code>.
    </p>
    </div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="txt" id="txt">txt: tables de correspondances au format texte</a></h2>
    

    <p>Lorsqu'un type-map <code>txt</code> est utilisé, la source-map
    est un chemin du système de fichiers vers un fichier de
    correspondances au format texte, contenant sur chaque ligne une
    paire clé/valeur séparées par un espace. Il est possible d'insérer
    des commentaires sous la forme de chaînes commençant par le caractère
    '#'.</p>

    <p>Voici un exemple d'entrées valides dans un fichier de
    correspondances :</p>

    <div class="example"><p><code>
      # Ligne de commentaires<br />
      <strong><em>clé</em> <em>valeur-substitution</em></strong><br />
      <strong><em>clé</em> <em>valeur-substitution</em></strong> # commentaire<br />
    </code></p></div>

    <p>Lorsque la table de correspondance fait l'objet d'une recherche,
    la valeur spécifiée est recherchée dans le premier champ, et si elle
    est trouvée, la valeur de substitution est renvoyée.</p>

    <p>Par exemple, nous pourrions utiliser un fichier de
    correspondances pour traduire des noms de produits en identifiants
    produits pour obtenir des URLs plus simples à mémoriser, en
    utilisant la recette suivante :</p>

    <p><strong>Product to ID configuration</strong></p>
    <pre class="prettyprint lang-config">RewriteMap product2id "txt:/etc/apache2/productmap.txt"
RewriteRule "^/product/(.*)" "/prods.php?id=${product2id:$1|NOTFOUND}" [PT]</pre>


    <p>Nous supposons ici que le script <code>prods.php</code> sait quoi
    faire lorsqu'il reçoit un argument <code>id=NOTFOUND</code>, dans
    le cas où le produit ne se trouve pas dans la table de
    correspondances.</p>

    <p>Le fichier <code>/etc/apache2/map-produit.txt</code> contient ce
    qui suit :</p>

    <div class="example"><h3>Fichier de correspondances Produit - Identifiant</h3><p><code>
##<br />
##  map-produit.txt - Fichier de correspondances Produit - Identifiant<br />
##<br />
<br />
TELEVISION 993<br />
STEREO     198<br />
CANNE-A-PECHE 043<br />
BALLON-BASKET 418<br />
TELEPHONE  328
    </code></p></div>

    <p>Ainsi, lorsqu'une requête pour
    <code>http://example.com/produit/TELEVISION</code> arrive, la directive
    <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> s'applique, et la
    requête est transformée en interne en <code>/prods.php?id=993</code>.</p>

    <div class="note"><h3>Note: fichiers .htaccess</h3>
    L'exemple donné est conçu pour être utilisé dans un contexte de
    serveur principal ou de serveur virtuel. Si vous voulez l'utiliser
    dans un fichier <code>.htaccess</code>, vous devrez supprimer le
    slash de début dans le modèle de réécriture afin que ce dernier
    puisse correspondre à toute URL :
    <pre class="prettyprint lang-config">RewriteRule "^product/(.*)" "/prods.php?id=${product2id:$1|NOTFOUND}" [PT]</pre>

    </div>

    <div class="note"><h3>Recherches mises en cache</h3>
    <p>
    Les clés de recherche sont mises en cache par httpd jusqu'à ce que
    le <code>mtime</code> (date de modification) du fichier de
    correspondances soit modifié, ou que le serveur httpd soit
    redémarré, ce qui améliore les performances pour les tables de
    correspondances consultées par de nombreuses requêtes.
    </p>
    </div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="rnd" id="rnd">rnd: Fichier texte à valeurs de substitution multiples
    choisies de manière aléatoire</a></h2>
    

    <p>Lorsque le type-map spécifié est <code>rnd</code>, la source est
    un chemin du système de fichiers vers un fichier de correspondances
    au format texte dont chaque ligne contient une clé, et une ou
    plusieurs valeurs séparées par le caractère <code>|</code>. Si une
    clé convient, une des valeurs correspondantes sera choisie de
    manière aléatoire.</p>

    <p>Par exemple, vous pouvez utiliser le fichier de correspondances
    et les directives suivants pour implémenter une répartition de
    charge aléatoire entre plusieurs serveurs d'arrière-plan, par
    l'intermédiaire d'un mandataire inverse. Les images sont envoyées
    vers un des serveurs de l'ensemble 'statique', tandis que tout le
    reste est envoyé vers un des serveurs de l'ensemble 'dynamique'.</p>

    <div class="example"><h3>Fichier de correspondances</h3><p><code>
##<br />
##  map.txt -- table de réécriture<br />

    <p>Ainsi, lorsqu'une image est demandée et que la première règle
    convient, <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> recherche la chaîne
    <code>statique</code> dans le fichier de correspondances qui
    renvoie un des noms de serveurs spécifiés de manière aléatoire,
    ce dernier étant utilisé dans la cible de la règle
    <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>.</p>

    <p>Si vous voulez qu'un des serveurs soit plus souvent sollicité que
    les autres (par exemple s'il possède plus de mémoire, et peut donc
    traiter d'avantage de requêtes), spécifiez-le plusieurs fois dans la
    liste des serveurs.</p>

<h2><a name="dbm" id="dbm">dbm: Fichier condensé DBM</a></h2>
    

    <p>Lorsque le type-map <code>dbm</code> est utilisé, la source est
    un chemin du système de fichiers vers un fichier de données DBM
    contenant des paires clé/valeur permettant d'effectuer la
    correspondance. Le fonctionnement est identique à celui du type-map
    <code>txt</code>, mais beaucoup plus rapide car un fichier DBM est
    indexé, alors qu'un fichier texte ne l'est pas. L'accès à la clé
    recherchée est donc plus rapide.</p>

    <p>Vous pouvez éventuellement spécifier un type dbm particulier :</p>

 <pre class="prettyprint lang-config">RewriteMap examplemap "dbm=sdbm:/etc/apache/mapfile.dbm"</pre>


    <p>Ce type peut être choisi parmi <code>sdbm</code>, <code>gdbm</code>,
    <code>ndbm</code> ou <code>db</code>. Il est
    cependant recommandé d'utiliser l'utilitaire <a href="../programs/httxt2dbm.html">httxt2dbm</a> fourni avec le
    serveur HTTP Apache, car il utilise la bibliothèque DBM appropriée,
    à savoir celle qui a été utilisée lors de la compilation de httpd.</p>

    <p>Pour créer un fichier dbm, créez tout d'abord un fichier de
    correspondances au format texte comme décrit dans la section <a href="#txt">txt</a>. Traitez ensuite ce fichier avec
    <code>httxt2dbm</code> :</p>

<div class="example"><p><code>
$ httxt2dbm -i fichier-map.txt -o fichier-map.map
</code></p></div>

<p>Vous pouvez alors faire référence au fichier obtenu dans votre
directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code> :</p>
<pre class="prettyprint lang-config">RewriteMap mapname "dbm:/etc/apache/mapfile.map"</pre>


<div class="note">
<p>Notez qu'avec certains types dbm, plusieurs fichiers possédant le
même nom de base sont créés. Par exemple, vous pouvez obtenir deux
fichiers nommés <code>fichier-map.map.dir</code> et
<code>fichier-map.map.pag</code>. Ceci est tout à fait normal, et vous
ne devez utiliser que le nom de base <code>fichier-map.map</code> dans votre
directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>.</p>
</div>

<div class="note"><h3>Mise en cache des recherches</h3>
<p>
    Les clés de recherche sont mises en cache par httpd jusqu'à ce que
    le <code>mtime</code> (date de modification) du fichier de
    correspondances soit modifié, ou que le serveur httpd soit
    redémarré, ce qui améliore les performances pour les tables de
    correspondances consultées par de nombreuses requêtes.

<h2><a name="prg" id="prg">prg: Programme de réécriture externe</a></h2>

    <p>Lorque le type-map <code>prg</code> est spécifié, la source est
    un chemin du système de fichiers vers un programme exécutable
    destiné à effectuer la mise en correspondance. Il peut s'agir d'un
    fichier binaire compilé, ou d'un programme en langage interprété
    comme Perl ou Python.</p>

    <p>Ce programme est lancé une fois au démarrage du serveur HTTP
    Apache, puis communique avec le moteur de réécriture via
    <code>STDIN</code> et <code>STDOUT</code>. En d'autres termes, pour
    chaque recherche de correspondance, il reçoit un argument via
    <code>STDIN</code>, et doit renvoyer en guise de réponse une chaîne
    terminée par un caractère nouvelle-ligne sur <code>STDOUT</code>. Si
    la recherche de correspondance est infructueuse, le programme doit
    l'indiquer en retournant la chaîne de quatre caractères
    "<code>NULL</code>".</p>

    <p>Les programmes de réécriture externes ne sont pas lancés s'il
    n'ont pas été définis dans un contexte où la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriteengine">RewriteEngine</a></code> est définie à
    <code>on</code>.</p>

    <p>Par défaut, les programmes de réécriture externes sont lancés par
    l'utilisateur/groupe qui a démarré httpd. Pour changer ce comportement, il
    est possible sur les systèmes de style Unix de spécifier un autre couple
    utilisateur/groupe via le troisième argument de la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritemap">RewriteMap</a></code>, et ceci au format
    <code>utilisateur:groupe</code>.</p>

    <p>Cette fonctionnalité utilise le mutex <code>rewrite-map</code>
    nécessaire à la fiabilité des communications avec le programme. Le
    mécanisme de mutex et le fichier verrou peuvent être définis via la
    directive <code class="directive"><a href="../mod/core.html#mutex">Mutex</a></code>.</p>

    <p>Voici un exemple simple qui remplace tous les tirets par des
    caractères de soulignement dans l'URI de la requête.</p>

    <p><strong>Configuration de la réécriture</strong></p>
    <pre class="prettyprint lang-config">RewriteMap d2u "prg:/www/bin/dash2under.pl" apache:apache
RewriteRule "-" "${d2u:%{REQUEST_URI}}"</pre>


    <p><strong>dash2under.pl</strong></p>
    <pre class="prettyprint lang-perl">    #!/usr/bin/perl
    $| = 1; # Turn off I/O buffering
    while (&lt;STDIN&gt;) {
        s/-/_/g; # Remplace tous les tirets par des caractères de soulignement
        print $_;
    }</pre>


<div class="note"><h3>Mises en garde !</h3>
<ul>
<li>Votre programme doit être le plus
simple possible. Si le programme se bloque, httpd va attendre
indéfiniment une réponse de sa part, et par conséquent ne répondra plus
aux requêtes.</li>
<li>Assurez-vous de bien désactiver la mise en tampon dans votre
programme. En Perl, ceci est effectué à la seconde ligne du script de
l'exemple - <code>$| = 1;</code> - La syntaxe sera bien entendu
différente dans
d'autres langages. Si les entrées/sorties sont mises en tampon, httpd va
attendre une sortie, et va par conséquent se bloquer.</li>
<li>Rappelez-vous qu'il n'existe qu'une copie du programme lancé au
démarrage du serveur, et que toutes les requêtes vont devoir passer par
ce goulot d'étranglement. Ceci peut provoquer des ralentissements
significatifs si de nombreuses requêtes doivent être traitées, ou si le
script lui-même est très lent.</li>

<h2><a name="dbd" id="dbd">dbd ou fastdbd: requête SQL</a></h2>
    

    <p>Lorsque le type-map <code>dbd</code> ou <code>fastdbd</code> est
    spécifié, la source est une requête SQL SELECT qui reçoit un
    argument et renvoie une seule valeur.</p>

    <p>Pour que cette requête puisse être exécutée,
    <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> doit être configuré pour attaquer la base
    de données concernée.</p>

    <p>Ce type-map existe sous deux formes. Avec le type-map
    <code>dbd</code>, la requête est exécutée à chaque demande, tandis
    qu'avec le type-map <code>fastdbd</code>, les recherches dans la
    base de données sont mises en cache en interne. <code>fastdbd</code>
    est donc plus efficace et donc plus rapide ; par contre, il ne
    tiendra pas compte des modifications apportées à la base de données
    jusqu'à ce que le serveur soit redémarré.</p>

    <p>Si une requête renvoie plusieurs enregistrements, un de ceux-ci

<h2><a name="InternalAPI" id="InternalAPI">Phases de l'API</a></h2>

      <p>Le traitement des requêtes par le serveur HTTP Apache se
      déroule en plusieurs phases. Au cours de chaque phase, un ou
      plusieurs modules peuvent être appelés pour traiter la partie
      concernée du cycle de vie de la requête. Les différentes phases
      peuvent consister en traduction d'URL en nom de fichier,
      authentification, autorisation, gestion de contenu ou journalisation (la
      liste n'est pas exhaustive).</p>

    <p>mod_rewrite agit dans deux de ces phases (ou accroches - hooks -
    comme on les nomme souvent) pour la réécriture des URLs.</p>

    <p>Tout d'abord, il utilise le hook traduction URL vers nom de
    fichier qui intervient après la lecture de la requête HTTP, mais
    avant le processus d'autorisation. Ensuite, il utilise le hook
    Fixup, qui intervient après les phases d'autorisation, après la
    lecture des fichiers de configuration de niveau répertoire (fichiers
    <code>.htaccess</code>), mais avant l'appel du gestionnaire de
    contenu.</p>

    <p>Ainsi, lorsqu'une requête arrive et une fois le serveur
    correspondant ou le serveur virtuel déterminé, le moteur de
    réécriture commence à traiter toute directive apparaissant dans la
    configuration de niveau serveur (autrement dit dans le
    fichier de configuration principal du serveur et les sections
    <code class="directive"><a href="../mod/core.html#virtualhost">&lt;Virtualhost&gt;</a></code>).
    Tout ce processus s'exécute au cours de la phase de traduction URL
    vers nom de fichier.</p>

    <p>Quelques étapes plus loin, une fois les répertoires de données
    finaux trouvés, les directives de configuration de niveau répertoire
    (fichiers <code>.htaccess</code> et sections <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>) sont appliquées. Ce processus
    s'exécute au cours de la phase Fixup.</p>

    <p>Dans tous ces cas, mod_rewrite réécrit le
    <code>REQUEST_URI</code> soit vers une nouvelle URL, soit vers un
    nom de fichier.</p>

    <p>Dans un contexte de niveau répertoire (autrement dit dans les
    fichiers <code>.htaccess</code> et les sections
    <code>Directory</code>), les règles de réécriture s'appliquent après
    la traduction de l'URL en nom de fichier. C'est pourquoi le chemin
    URL auquel mod_rewrite compare initialement les directives
    <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> est le
    chemin complet vers le nom de fichier traduit amputé de la partie
    répertoires (y compris le dernier slash).</p>

    <p>Un exemple : si les règles se trouvent dans
    /var/www/foo/.htaccess et si une requête pour /foo/bar/baz est
    traité, une expression comme ^bar/baz$ correspondra.</p>

    <p>Si une substitution intervient dans un contexte de répertoire,
    une nouvelle sous-requête interne est générée avec la nouvelle URL,
    ce qui relance le traitement des phases de la requête. Si la
    substitution est un chemin relatif, la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> détermine le chemin URL
    devant préfixer cette substitution. Dans un contexte de répertoire,
    il faut s'assurer de créer des règles qui
    n'effectueront pas de substitution au
    cours d'une passe ultérieure du processus de réécriture au niveau
    répertoire afin d'éviter les bouclages . Voir <a href="http://wiki.apache.org/httpd/RewriteLooping">Bouclage dans le
    processus de réécriture</a> pour une discussion plus détaillée à
    propos de ce problème.</p>

    <p>En conséquence de cette manipulation de l'URL , vous devrez
    pensez à confectionner différemment vos règles de réécriture dans un
    contexte de niveau répertoire. En particulier, rappelez-vous que le
    chemin de répertoire sera absent de l'URL que vos règles de
    réécriture verront. Voici quelques exemples qui permettront de
    clarifier les choses :</p>

    <table class="bordered">

        <tr>
            <th>Position de la règle</th>
            <th>Règle</th>
        </tr>

        <tr>
            <td>Section VirtualHost</td>
            <td>RewriteRule "^/images/(.+)\.jpg" "/images/$1.gif"</td>
        </tr>

        <tr>
            <td>Fichier .htaccess à la racine des documents</td>
            <td>RewriteRule "^images/(.+)\.jpg" "images/$1.gif"</td>
        </tr>

        <tr>
            <td>Fichier .htaccess dans le répertoire images</td>
            <td>RewriteRule "^(.+)\.jpg" "$1.gif"</td>
        </tr>

    </table>

    <p>Pour une étude plus approfondie de la manière dont mod_rewrite
    manipule les URLs dans les différents contextes, vous pouvez
    consulter les <a href="../mod/mod_rewrite.html#logging">entrées du
    journal</a> générées au cours du processus de réécriture.</p>

<div class="section">
<h2><a name="InternalRuleset" id="InternalRuleset">Traitement du jeu de règles</a></h2>

      <p>Maintenant, quand mod_rewrite se lance dans ces deux phases de
      l'API, il lit le jeu de règles configurées depuis la structure
      contenant sa configuration (qui a été elle-même créée soit au
      démarrage d'Apache pour le contexte du serveur, soit lors du
      parcours des répertoires par le noyau d'Apache pour le contexte de
      répertoire). Puis le moteur de réécriture est démarré avec le jeu
      de règles contenu (une ou plusieurs règles associées à leurs
      conditions). En lui-même, le mode opératoire du moteur de
      réécriture d'URLs est exactement le même dans les deux contextes
      de configuration. Seul le traitement du résultat final diffère.</p>

      <p>L'ordre dans lequel les règles sont définies est important car
      le moteur de réécriture les traite selon une chronologie
      particulière (et pas très évidente). Le principe est le suivant :
      le moteur de réécriture traite les règles (les directives <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>) les unes
      à la suite des autres, et lorsqu'une règle s'applique, il parcourt
      les éventuelles conditions (directives
      <code>RewriteCond</code>directives) associées.
      Pour des raisons historiques, les
      conditions précèdent les règles, si bien que le déroulement du
      contrôle est un peu compliqué. Voir la figure 1 pour plus de
      détails.</p>
<p class="figure">
      <img src="../images/rewrite_process_uri.png" alt="Flux des comparaisons des directives RewriteRule et RewriteCond" /><br />
      <dfn>Figure 1:</dfn>Déroulement du contrôle à travers le jeu de
      règles de réécriture
</p>
      <p>L'URL est tout d'abord comparée au
      <em>Modèle</em> de chaque règle. Lorsqu'une règle ne s'applique
      pas, mod_rewrite stoppe immédiatement le traitement de cette règle
      et passe à la règle suivante. Si l'URL correspond au
      <em>Modèle</em>, mod_rewrite recherche la présence de conditions
      correspondantes (les directives Rewritecond apparaissant dans la
      configuration juste
      avant les règles de réécriture). S'il n'y en a pas, mod_rewrite remplace
      l'URL par une chaîne élaborée à partir de la chaîne de
      <em>Substitution</em>, puis passe à la règle suivante. Si des
      conditions sont présentes, mod_rewrite lance un bouclage
      secondaire afin de les traiter selon l'ordre dans lequel elles
      sont définies. La logique de traitement des conditions est
      différente : on ne compare pas l'URL à un modèle. Une chaîne de
      test <em>TestString</em> est tout d'abord élaborée en développant
      des variables, des références arrières, des recherches dans des
      tables de correspondances, etc..., puis cette chaîne de test est
      comparée au modèle de condition <em>CondPattern</em>. Si le modèle
      ne correspond pas, les autres conditions du jeu ne sont pas
      examinées et la règle correspondante ne s'applique pas. Si le
      modèle correspond, la condition suivante est examinée et ainsi de
      suite jusqu'à la dernière condition. Si toutes les conditions sont
      satisfaites, le traitement de la règle en cours se poursuit avec
      le remplacement de l'URL par la chaîne de <em>Substitution</em>.</p>

<h2><a name="introduction" id="introduction">Introduction</a></h2>
<p>Le comportement d'une directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> peut être modifié par un ou
plusieurs drapeaux. Les drapeaux sont situés en fin de règle, entourés
de crochets, et séparés le cas échéant par des virgules.</p>
<pre class="prettyprint lang-config">RewriteRule pattern target [Flag1,Flag2,Flag3]</pre>


<p>Chaque drapeau (à quelques exceptions près)
possède une forme courte, comme <code>CO</code>, ainsi qu'une forme longue,
comme <code>cookie</code>. Bien que
la forme courte soit la plus couramment utilisée, nous vous recommandons
de vous familiariser avec les drapeaux sous leur forme longue, afin de
bien mémoriser ce que chaque drapeau est supposé faire.
Certains drapeaux acceptent un ou plusieurs arguments. Les drapeaux ne
sont pas sensibles à la casse.</p>

<p>Les drapeaux qui modifient les métadonnées associées à la requête
(T=, H=, E=) n'ont aucun effet dans un contexte de répertoire ou de
fichier htaccess, lorsqu'une substitution (autre que '-') est effectuée
au cours de la même passe du processus de réécriture.
</p>

<p>Chaque drapeau disponible est présenté ici, avec un exemple
d'utilisation.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_b" id="flag_b">B (échappement dans les références arrières)</a></h2>
<p>Avec le drapeau [B], la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> échappe les caractères
non-alphanumériques avant d'appliquer la transformation. A partir
de la version 2.4.26, vous pouvez limiter l'échappement dans les
références arrières à une liste de caractères que vous pouvez spécifiez comme
dans cet exemple : <code>[B=#?;]</code>. Notez que l'espace peut faire
partie de la liste des caractères à échapper, mais qu'il ne doit pas
être le dernier caractère de cette liste.
</p>

<p><code>mod_rewrite</code> doit supprimer les séquences d'échappement
des URLs avant leur
mise en correspondance avec le système de fichiers ; les séquences
d'échappement sont donc supprimées des références arrières au moment où
ces dernières sont appliquées. Avec le drapeau B, les caractères
non-alphanumériques des références arrières seront échappés. Considérons
par exemple cette règle :</p>

<pre class="prettyprint lang-config">RewriteRule "^search/(.*)$" "/search.php?term=$1"</pre>


<p>Soit le terme de recherche 'x &amp; y/z' ; un navigateur va le coder
en 'x%20%26%20y%2Fz', transformant la requête en
'search/x%20%26%20y%2Fz'. Sans le drapeau B, cette règle de réécriture
va réécrire la requête en 'search.php?term=x &amp; y/z', ce qui ne
correspond pas à une URL valide et cette dernière sera encodée en
<code>search.php?term=x%20&amp;y%2Fz=</code>, ce qui ne correspond pas à
ce que l'on souhaitait.</p>

<p>Avec le drapeau B, les paramètres sont réencodés avant d'être passés
à l'URL résultante, ce qui fournit une réécriture correcte en
<code>/search.php?term=x%20%26%20y%2Fz</code>.</p>

<pre class="prettyprint lang-config">RewriteRule "^search/(.*)$" "/search.php?term=$1" [B,PT]</pre>


<p>Notez que vous devrez peut-être aussi définir la
directive <code class="directive"><a href="../mod/core.html#allowencodedslashes">AllowEncodedSlashes</a></code>
à <code>On</code> pour
que cet exemple particulier fonctionne, car httpd ne permet pas les
slashes encodés dans les URLs, et renvoie une erreur 404 s'il en
rencontre un.</p>

<p>Ce processus d'échappement est en particulier nécessaire dans le
contexte d'un mandataire, où l'accès au serveur d'arrière-plan échouera
si on présente à ce dernier une URL non échappée.</p>

<p>Une alternative à ce drapeau consiste à utiliser une directive
<code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> pour capturer
%{THE_REQUEST}, les chaînes capturées se présentant
alors sous la forme codée.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_bnp" id="flag_bnp">BNP|backrefnoplus (ne pas échapper
l'espace en +)</a></h2>
<p>Si le drapeau [BNP] est spécifié, la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> échappera le caractère
espace en %20 au lieu de '+' dans les références arrières. Ceci s'avère
utile lorsque la référence arrière est utilisée dans la partie chemin,
et non dans les paramètres de la requête.</p>

<p>Ce drapeau est disponible à partir de la version 2.4.26 du serveur HTTP
Apache.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_c" id="flag_c">C|chain</a></h2>
<p>Le drapeau [C] ou [chain] indique que la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> est chaînée avec la
suivante. Autrement dit, si la règle s'applique, elle est traitée
normalement et passe le contrôle à la règle suivante. Par contre, si
elle ne s'applique pas, la règle suivante, ainsi que toutes les règles
chaînées qui suivent, seront sautées.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_co" id="flag_co">CO|cookie</a></h2>
<p>Le drapeau [CO], ou [cookie], vous permet de définir un cookie
lorsqu'une règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code>
s'applique. Il possède trois arguments obligatoires et
cinq arguments optionnels.</p>

<p>La syntaxe complète de ce drapeau, avec tous ses attributs, est la
suivante :</p>

<div class="example"><p><code>
[CO=NAME:VALUE:DOMAIN:lifetime:path:secure:httponly:samesite]
</code></p></div>

<p>Si un caractère littéral ':' doit être insérer dans un des champs du
cookie, une autre syntaxe est disponible. Pour utiliser cette syntaxe
alternative, le contenu du champ "Name" doit être précédé du caractère
';', et les sépateurs de champs deviendront des ';'.</p>

<div class="example"><p><code>
[CO=;NAME;VALUE:MOREVALUE;DOMAIN;lifetime;path;secure;httponly;samesite]
</code></p></div>

<p>Vous devez déclarer un nom, une valeur et un domaine pour que
le cookie puisse être défini.</p>


<dl>
<dt>Domain</dt>
<dd>Le domaine pour lequel vous souhaitez que le cookie soit valide. Ce
peut être un nom de serveur, comme <code>www.example.com</code>, ou un
domaine, comme <code>.example.com</code>. Il doit comporter au moins
deux parties séparées par un point. C'est à dire que vous ne pouvez pas
utiliser les valeurs <code>.com</code> ou <code>.net</code>. En effet,
ce style de cookie est interdit par le modèle de sécurité des cookies.</dd>
</dl>

<p>Vous pouvez aussi définir les valeurs suivantes :</p>

<dl>
<dt>Lifetime</dt>
<dd>La durée de vie du cookie, en minutes.</dd>
<dd>Une valeur de 0 indique une durée de vie correspondant à la session
courante du navigateur. Il s'agit de la valeur par défaut.</dd>

<dt>Path</dt>
<dd>Le chemin, sur le site web concerné, pour lequel le cookie est
valide, du style <code>/clients/</code> or
<code>/fichiers/telechargement/</code>.</dd>
<dd>La valeur par défaut est <code>/</code> - c'est à dire l'ensemble du
site web.</dd>

<dt>Secure</dt>
<dd>Si cet argument a pour valeur <code>secure</code>,
<code>true</code>, ou <code>1</code>, le cookie ne pourra être transmis
que dans le cadre d'une connexion sécurisée (https).</dd>

<dt>httponly</dt>
<dd>Si cet argument a pour valeur <code>HttpOnly</code>,
<code>true</code>, ou <code>1</code>, le cookie aura son drapeau
<code>HttpOnly</code> activé, ce qui signifie qu'il sera inaccessible au
code JavaScript pour les navigateurs qui supportent cette
fonctionnalité.</dd>

<dt>samesite</dt>
<dd>S'il est différent de <code>false</code> ou <code>0</code>, l'attribut
<code>SameSite</code> est défini à la valeur spécifiée. Les valeurs typiques
sont <code>None</code>, <code>Lax</code> et <code>Strict</code>. Disponible à
partir de la version 2.5.1 du serveur HTTP Apache.</dd>
</dl>

<p>Voici un exemple :</p>

<pre class="prettyprint lang-config">RewriteEngine On
RewriteRule "^/index\.html" "-" [CO=frontdoor:yes:.example.org:1440:/]</pre>


<p>Dans l'exemple ci-dessus, la règle ne réécrit
pas la requête. La cible de réécriture "-"
indique à mod_rewrite de transmettre la requête sans
modification. Par contre, il
définit un cookie nommé 'frontdoor' avec une valeur 'yes'. Le cookie est
valide pour tout hôte situé dans le domaine <code>.example.org</code>. Sa
durée de vie est limitée à 1440 minutes (24 heures), et il sera renvoyé
pour tous les URIs.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_dpi" id="flag_dpi">DPI|discardpath</a></h2>
<p>Avec le drapeau DPI, la partie PATH_INFO de l'URI
réécrit est supprimée.</p>
<p>Ce drapeau est disponible dans les versions 2.2.12 et supérieures.</p>
<p>Dans un contexte de répertoire, l'URI mis en comparaison par chaque
règle <code class="directive">RewriteRule</code> est la concaténation des
valeurs courantes de l'URI et de PATH_INFO.</p>

<p>L'URI courant peut être l'URI initial tel qu'il a été fourni par le
client, le résultat d'une passe précédente du processus de réécriture,
ou le résultat de la règle précédente dans le processus courant de
réécriture.</p>

<p>Par contre, la partie PATH_INFO ajoutée à l'URI avant chaque règle ne
reflète que la valeur de PATH_INFO avant la passe courante du processus
de réécriture. En conséquence, si de larges portions de l'URI
correspondent et sont traduites via plusieurs directives
<code class="directive">RewriteRule</code>, sans prendre en compte
quelles parties de l'URI provenaient du PATH_INFO courant, l'URI final
pourra se voir ajouter plusieurs copies de PATH_INFO.</p>

<p>Utilisez ce drapeau pour toute substitution où la présence du PATH_INFO qui
résultait de la mise en correspondance précédente de cette requête avec
le système de fichier n'est pas nécessaire. Avec ce drapeau, le
PATH_INFO établi avant que cette passe du processus de réécriture ne
débute est oublié. PATH_INFO ne sera pas recalculé tant que la passe
courante du processus de réécriture ne sera pas achevée. Les règles
suivantes de cette passe ne verront que le résultat direct des
substitutions, sans aucun PATH_INFO ajouté.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_e" id="flag_e">E|env</a></h2>
<p>Avec le drapeau [E], ou [env], vous pouvez définir la valeur d'une
variable d'environnement. Notez que certaines variables d'environnement
peuvent être définies après le traitement de la règle, annulant par
la-même ce que vous avez défini. Voir le <a href="../env.html">document
sur les variables d'environnement</a> pour plus de détails sur le
fonctionnement des variables d'environnement.</p>

<p>La syntaxe complète pour ce drapeau est :</p>

<pre class="prettyprint lang-config">[E=!VAR]</pre>


<p><code>VAL</code> peut comporter des références arrières
(<code>$N</code> ou <code>%N</code>) qui seront développées.</p>

<p>En utilisant la version courte</p>

<div class="example"><p><code>
[E=VAR]
</code></p></div>

<p>vous pouvez définir la variable d'environnement nommée
<code>VAR</code> avec une valeur vide.</p>

<p>La forme</p>

<div class="example"><p><code>
[E=!VAR]
</code></p></div>

<p>permet d'annuler la définition de la variable <code>VAR</code>.</p>

<p>Les variables d'environnement s'emploient dans différents contextes,
comme les programmes CGI, d'autres directives RewriteRule, ou des
directives CustomLog.</p>

<p>L'exemple suivant définit une variable d'environnement nommée 'image'
avec une valeur de '1' si l'URI de la requête correspond à un fichier
image. Cette variable d'environnement est ensuite utilisée pour exclure
une telle requête du journal des accès.</p>

<div class="example"><p><code>
RewriteRule "\.(png|gif|jpg)" "-" [E=image:1]<br />
CustomLog "logs/access_log" combined env=!image
</code></p></div>

<p>Notez que le même effet peut être obtenu à l'aide de la directive
<code class="directive"><a href="../mod/mod_setenvif.html#setenvif">SetEnvIf</a></code>. Cette technique
est présentée à titre d'exemple et non de recommandation.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_end" id="flag_end">END</a></h2>
<p>L'utilisation du drapeau [END] permet non seulement de terminer le
processus de réécriture en cours (comme [L]), mais aussi d'empêcher tout
processus de réécriture ultérieur dans un contexte de répertoire
(htaccess).</p>

<p>Ceci ne s'applique pas aux nouvelles requêtes résultant d'une
redirection externe.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_f" id="flag_f">F|forbidden</a></h2>
<p>L'utilisation du drapeau [F] permet de faire envoyer par le serveur au
client un code de statut "403 Forbidden". Le même effet peut être obtenu à
l'aide de la directive <code class="directive"><a href="../mod/mod_access_compat.html#deny">Deny</a></code>,
mais ce drapeau offre plus de souplesse dans l'attribution d'un statut
Forbidden.</p>

<p>La règle suivante va interdire la téléchargement de fichiers
<code>.exe</code> depuis votre serveur.</p>

<pre class="prettyprint lang-config">RewriteRule "\.exe" "-" [F]</pre>


<p>Cet exemple utilise la syntaxe "-" pour la cible de réécriture, ce
qui signifie que l'URI de la requête n'est pas modifié. Il n'y a aucune
raison de réécrire un URI, si vous avez l'intention d'interdire la
requête.</p>

<p>Lorsqu'on utilise [F], [L] est implicite - c'est à dire que la
réponse est renvoyée immédiatement, et aucune autre règle n'est évaluée.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_g" id="flag_g">G|gone</a></h2>
<p>Le drapeau [G] permet de faire envoyer par le serveur un code de statut
"410 Gone" avec la réponse. Ce code indique qu'une ressource qui était
disponible auparavant ne l'est plus actuellement.</p>

<p>Comme dans le cas du drapeau [F], on utilise en général la syntaxe
"-" pour la cible de réécriture lorsqu'on utilise le drapeau [G] :</p>

<pre class="prettyprint lang-config">RewriteRule "oldproduct" "-" [G,NC]</pre>


<p>Lorsqu'on utilise [G], [L] est implicite - c'est à dire que la
réponse est renvoyée immédiatement, et aucune autre règle n'est évaluée.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_h" id="flag_h">H|handler</a></h2>
<p>Force le traitement de la requête résultante par le gestionnaire
spécifié. Par exemple, on peut utiliser ce drapeau pour forcer
l'interprétation de tous les fichiers sans extension par le gestionnaire
php :</p>

<pre class="prettyprint lang-config">RewriteRule "!\." "-" [H=application/x-httpd-php]</pre>


<p>
L'expression rationnelle ci-dessus - <code>!\.</code> - correspond à
toute requête qui ne contient pas le caractère <code>.</code>.
</p>
<p>On peut aussi utiliser ce drapeau pour forcer l'utilisation d'un
certain gestionnaire en fonction de certaines conditions. Par exemple,
l'extrait suivant utilisé dans un contexte de niveau serveur permet de
faire en sorte que les fichiers <code>.php</code> soient
<em>affichés</em> par <code>mod_php</code> dans le cas où ils font
l'objet d'une requête avec l'extension <code>.phps</code> :</p>

<pre class="prettyprint lang-config">RewriteRule "^(/source/.+\.php)s$" "$1" [H=application/x-httpd-php-source]</pre>



<p>L'expression rationnelle ci-dessus -
<code>^(/source/.+\.php)s$</code> - va correspondre à toute requête qui
débutera par <code>/source/</code>, continuera par 1 ou n caractères
puis par <code>.phps</code>. La référence arrière $1 fait référence à la
correspondance capturée entre parenthèses de l'expression
rationnelle.</p>


</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_l" id="flag_l">L|last</a></h2>
<p>Lorsque le drapeau [L] est présent, <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>
arrête le traitement du jeu de règles. Cela signifie dans la plupart des
situations que si la règle s'applique, aucune autre règle ne sera
traitée. Ce drapeau correspond à la commande Perl <code>last</code>, ou
à la commande <code>break</code> en C. Utilisez ce drapeau pour indiquer
que la règle courante doit être appliquée immédiatement, sans tenir
compte des règles ultérieures.</p>

<p>Si vous utilisez des règles <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> dans des fichiers
<code>.htaccess</code> ou des sections <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>, il est important d'avoir quelques
notions sur la manière dont les règles sont traitées. Pour simplifier,
une fois les règles traitées, la requête réécrite est passée à nouveau
au moteur d'interprétation des URLs afin que ce dernier puisse la
traiter. Il est possible qu'au cours du traitement de la requête
réécrite, le fichier <code>.htaccess</code> ou la section <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> soient à nouveau
rencontrés, entraînant un nouveau traitement du jeu de règles depuis le
début. Cette situation se présente le plus souvent lorsqu'une des règles
provoque une redirection - interne ou externe - ce qui réinitialise le
traitement de la requête.</p>

<p>Si vous utilisez des directives <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> dans un de ces contextes,
il importe par conséquent de prévoir explicitement des étapes permettant
d'éviter un bouclage infini sur les règles,
et de ne pas compter seulement sur
le drapeau [L] pour terminer l'exécution d'une série de règles, comme
décrit ci-dessous.</p>

<p>Un autre drapeau, [END], permet non seulement d'interrompre le cycle
courant du processus de réécriture, mais aussi d'empêcher toute
réécriture ultérieure dans le contexte de répertoire (htaccess). Ceci ne
s'applique pas aux nouvelles requêtes résultant de redirections
externes.</p>

<p>Dans l'exemple donné ici, toute requête est réécrite en
<code>index.php</code>, la requête originale étant ajoutée comme chaîne
de requête en argument à <code>index.php</code> ; cependant, la
directive <code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> permet de s'assurer que si
la requête concerne déjà <code>index.php</code>, la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> sera sautée.</p>

<pre class="prettyprint lang-config">RewriteBase "/"
RewriteCond "%{REQUEST_URI}" "!=/index.php"
RewriteRule "^(.*)" "/index.php?req=$1" [L,PT]</pre>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_n" id="flag_n">N|next</a></h2>
<p>Le drapeau [N] provoque un redémarrage du traitement des règles
depuis le début, en utilisant le résultat du jeu de règles, sous
réserve qu'il existe un point de démarrage ; à utiliser avec précautions
car il peut provoquer un bouclage infini.
</p>
<p>
Le drapeau [Next] peut servir, par exemple,
à remplacer de manière répétitive
une chaîne de caractère ou une lettre dans une requête. Dans l'exemple
suivant, chaque occurence de A sera remplacée par B dans la requête, et
ceci jusqu'il n'y ait plus de A à remplacer.
</p>

<pre class="prettyprint lang-config">RewriteRule "(.*)A(.*)" "$1B$2" [N]</pre>


<p>Vous pouvez vous représenter ce traitement comme une boucle
<code>while</code> : tant que le modèle de la règle correspond (c'est à
dire, tant que l'URI contient un <code>A</code>),
effectuer la substitution (c'est à dire, remplacer le <code>A</code> par
un <code>B</code>).</p>

<p>A partir de la version 2.4.8, ce module renvoie une erreur après
32000 itérations afin d'éviter les boucles infinies. Ce nombre maximum
d'itération peut être modifié via le drapeau N.</p>
<pre class="prettyprint lang-config"># On veut remplacer 1 caractère à chaque itération de la boucle
RewriteRule "(.+)[&gt;&lt;;]$" "$1" [N=64000]
# ... ou s'arrêter après 10 itérations
RewriteRule "(.+)[&gt;&lt;;]$" "$1" [N=10]</pre>

<h2><a name="flag_nc" id="flag_nc">NC|nocase</a></h2>
<p>Avec le drapeau [NC], le modèle de la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> est comparé à la requête de
manière insensible à la casse. C'est à dire que cette comparaison
s'effectue sans tenir compte des majuscules/minuscules dans l'URI
comparé.</p>

<p>Dans l'exemple suivant, toute requête pour un fichier image sera
transmise par Apache à votre serveur d'images dédié. La correspondance est
insensible à la casse, si bien que par exemple, <code>.jpg</code> aussi
bien que <code>.JPG</code> seront acceptés.</p>

<pre class="prettyprint lang-config">RewriteRule "(.*\.(jpg|gif|png))$" "http://images.example.com$1" [P,NC]</pre>

<p>Par défaut, les caractères spéciaux, comme <code>&amp;</code> et

</p>

<pre class="prettyprint lang-config">RewriteRule "^/anchor/(.+)" "/bigpage.html#$1" [NE,R]</pre>


<p>
Dans l'exemple ci-dessus, <code>/anchor/xyz</code> est réécrit en
<code>/bigpage.html#xyz</code>. En l'absence du drapeau [NE], le #
aurait été converti en son équivalent hexadécimal, <code>%23</code>, ce
qui aurait provoqué un code d'erreur "404 Not Found".

<div class="section">
<h2><a name="flag_ns" id="flag_ns">NS|nosubreq</a></h2>
<p>Le drapeau [NS] empêche la règle de s'appliquer aux sous-requêtes.
Par exemple, une page incluse au moyen d'une SSI (Server
Side Include) est une sous-requête, et vous ne voudrez probablement pas que
la réécriture s'applique à ces sous-requêtes. Ainsi, lorsque
<code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> recherche des informations à propos des
fichiers par défaut du répertoire (comme les fichiers
<code>index.html</code>), il s'agit d'une sous-requête interne, et vous
ne désirez en général pas que ces sous-requêtes soient réécrites. Cette
réécriture
n'est pas toujours utile pour les sous-requêtes, et peut même causer des
erreurs si l'ensemble du jeu de règles est appliqué. L'utilisation de
ce drapeau permet d'exclure les règles qui peuvent poser problème.</p>

<p>Comment déterminer si vous devez utiliser cette règle ou non : si
vous préfixez les URLs avec des scripts CGI, afin de forcer leur
traitement par le script CGI, vous vous exposez à des problèmes (ou du
moins à une surcharge significative) avec les sous-requêtes. Dans ces
cas, vous devez utiliser ce drapeau.</p>

<p>
Les images, scripts java, ou fichiers css, chargés en tant que partie
d'une page html, ne sont pas des sous-requêtes - le navigateur les
appelle sous forme de requêtes HTTP à part entière.

<div class="section">
<h2><a name="flag_p" id="flag_p">P|proxy</a></h2>
<p>L'utilisation du drapeau [P] entraîne le traitement de la requête par
le module <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>, et ceci via une requête de
mandataire. Par exemple, si vous voulez que toutes les requêtes d'images
soient traitées par un serveur d'images annexe, vous pouvez utiliser
une règle de ce style :</p>

<pre class="prettyprint lang-config">RewriteRule "/(.*)\.(jpg|gif|png)$" "http://images.example.com/$1.$2" [P]</pre>


<p>L'utilisation du drapeau [P] provoque aussi l'effet du drapeau [L] -
autrement dit, la requête est immédiatement envoyée au mandataire, et
toute règle ultérieure sera ignorée.</p>

<p>
Vous devez vous assurer que la chaîne de substitution soit un URI valide
(commençant typiquement par <code>http://</code><em>nom-serveur</em>)
qui puisse être traitée par le module <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>. Dans
le cas contraire, le module mandataire vous renverra une erreur.
L'utilisation de ce drapeau implémente de manière plus puissante la
directive <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>, pour
faire correspondre le contenu distant à l'espace de nommage du serveur
local.</p>

<div class="warning">
      <h3>Avertissement à propos de la sécurité</h3>
      <p>Lors de la construction de l'URL cible de la règle, il convient
      de prendre en compte l'impact en matière de sécurité qu'aura le
      fait de permettre au client d'influencer le jeu d'URLs pour
      lesquelles votre serveur agira en tant que mandataire.
      Assurez-vous que la partie protocole://nom-serveur de l'URL soit
      fixe, ou ne permette pas au client de l'influencer induement.</p>
</div>

<div class="warning">
      <h3>Avertissement au sujet des performances</h3>
      <p>Utiliser ce drapeau fait intervenir <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> sans la gestion des connexions
      persistantes, ce qui signifie que vous obtiendrez des performances meilleurs si vous utilisez
      <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> ou <code class="directive"><a href="../mod/mod_proxy.html#proxypassmatch">ProxyPassMatch</a></code>.</p>
      <p>Ceci est du au fait que ce drapeau induit l'utilisation du worker par défaut, qui
      ne gère pas la mise en commun et la réutilisation des connexions.</p>
      <p>Partout où cela est possible, préférez l'utilisation de ces directives.</p>

<h2><a name="flag_pt" id="flag_pt">PT|passthrough</a></h2>

<p>
Par défaut, la cible (ou chaîne de substitution) d'une règle
RewriteRule est sensée être un chemin de fichier. Avec le drapeau [PT],
par contre, elle est traitée comme un URI. Autrement dit, avec le
drapeau [PT], le résultat de la règle  <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> est passé à nouveau au
système de mise en correspondance des URLs avec le système de fichiers,
de façon à ce que les systèmes de mise en correspondance basés sur les
chemins de fichiers, comme la directive <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code>, ou <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>, par exemple, puissent avoir une
chance d'accomplir leur tâche.
</p>

<p>
Si par exemple, vous avez un <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> pour /icons, et une règle  <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> qui renvoie vers /icons,
vous devez utiliser le drapeau [PT] pour être sûr que l'<code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> sera bien évalué.
</p>

<pre class="prettyprint lang-config">Alias "/icons" "/usr/local/apache/icons"
RewriteRule "/pics/(.+)\.jpg$" "/icons/$1.gif" [PT]</pre>


<p>
Dans l'exemple précédent, en l'absence du drapeau [PT], l'Alias aurait
été ignoré, ce qui aurait provoqué une erreur 'File not found'.
</p>

<p>Avec le drapeau <code>PT</code>, le drapeau <code>L</code> est
implicite : la réécriture s'arrêtera afin de transmettre la requête à la
phase suivante du traitement.</p>

<p>Notez que le drapeau <code>PT</code> est implicite dans des contextes
de répertoire comme les sections <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> ou les fichiers
<code>.htaccess</code>. Le seul moyen de contourner ceci consiste à
réécrire vers <code>-</code>.</p>

<h2><a name="flag_qsa" id="flag_qsa">QSA|qsappend</a></h2>
<p>
Quand l'URI de remplacement contient une chaîne de requête, le
comportement par défaut de la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> est de supprimer la <code>
query string</code> (il s'agit des paramètres éventuellement passés dans l'URL après le
caractère <code>?</code>, usuellement pour les formulaires traités par la
méthode HTTP <code>GET</code>) existante, et de la remplacer par celle nouvellement créée.
Avec le drapeau [QSA], les chaînes de requête peuvent être combinées.
</p>

<p>Considérons la règle suivante :</p>

<pre class="prettyprint lang-config">RewriteRule "/pages/(.+)" "/page.php?page=$1" [QSA]</pre>


<p>Avec le drapeau [QSA], une requête pour
<code>/pages/123?one=two</code> sera réécrite en
<code>/page.php?page=123&amp;one=two</code>. Sans le drapeau [QSA], la
même requête sera réécrite en <code>/page.php?page=123</code> -
autrement dit, la chaîne de requête (<code>query string</code>) existante sera supprimée.
</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_qsd" id="flag_qsd">QSD|qsdiscard</a></h2>
<p>
Lorsque l'URI de la requête contient une chaîne de paramètres, et si
l'URI cible n'en contient pas, le comportement par défaut de la
directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> consiste à copier cette
chaîne de paramètres dans l'URI cible. Avec le drapeau [QSD], la chaîne
de paramètres est supprimée.
</p>

<p>Ce drapeau est disponible dans les versions 2.4.0 et supérieures.</p>

<p>
Lorsque les drapeaux [QSD] et [QSA] sont utilisés ensemble, c'est le
drapeau [QSD] qui l'emporte.
</p>

<p>
Si l'URI cible possède une chaîne de paramètres, le comportement par
défaut sera respecté - c'est à dire que la chaîne de paramètres
originale sera supprimée et remplacée par la chaîne de paramètres de
l'URI cible.

<div class="section">
<h2><a name="flag_qsl" id="flag_qsl">QSL|qslast</a></h2>
<p>
Par défaut, le premier (le plus à gauche) point d'interrogation de la
substitution sépare le chemin de la requête de sa chaîne de paramètres. Avec le
drapeau [QSL] au contraire, les deux composants seront séparés en utilisant le
dernier (le plus à droite) point d'interrogation.</p>

<p>
Cela peut s'avérer utile lorsqu'on recherche un fichier dont le nom contient des
points d'interrogation. Si aucune chaîne de paramètre n'est présente dans la
substitution, il est alors possible d'ajouter un point d'interrogation à la fin
et d'utiliser ce drapeau.</p>

<p>Ce drapeau est disponible à partir de la version 2.4.19 du serveur HTTP
Apache.</p>

<div class="section">
<h2><a name="flag_r" id="flag_r">R|redirect</a></h2>
<p>
L'utilisation du drapeau [R] provoque l'envoi d'une redirection au
navigateur. Si une URL pleinement qualifiée (FQDN - fully qualified domain name)
 est spécifiée (c'est à dire incluant <code>http://nom-du-serveur/</code>),
 une redirection sera effectuée vers cette adresse. Dans le cas contraire,
 le protocole courant, le nom du serveur et le numéro de port seront
 utilisés pour générer l'URL envoyée avec la redirection.
</p>

<p><em>Tout</em> code de statut de réponse HTTP valide peut être
spécifié, en utilisant la syntaxe [R=305], le code de statut 302 étant
utilisé par défaut si aucun code n'est spécifié. Le code de statut
spécifié n'est pas nécessairement un code de statut
de redirection (3xx). Cependant, si le code de statut est en dehors de la plage des codes de
redirection (300-399), la chaîne de substitution est entièrement
supprimée, et la réécriture s'arrête comme si le drapeau <code>L</code>
était utilisé.</p>

<p>En plus des codes de statut de réponse, vous pouvez spécifier les
codes de redirection en utilisant leurs noms symboliques :
<code>temp</code> (défaut), <code>permanent</code>, ou
<code>seeother</code>.</p>

<p>
Vous utiliserez presque toujours [R] en conjonction avec [L] (c'est à
dire [R,L]), car employé seul, le drapeau [R] préfixe l'URI avec
<code>http://cet-hôte[:ce-port]</code>, mais passe ensuite cette adresse
à la règle suivante, ce qui provoquera le plus souvent des
avertissements 'Invalid URI in request'.

<div class="section">
<h2><a name="flag_s" id="flag_s">S|skip</a></h2>
<p>Le drapeau [S] sert à sauter des règles que vous ne voulez pas voir
exécuter. La syntaxe du drapeau [S] est [S=<em>N</em>], où
<em>N</em> correspond au nombre de règles à sauter (sous
réserve que la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> corresponde).
Ceci peut s'interpréter comme une instruction
<code>goto</code>  dans votre jeu de règles de réécriture. Dans
l'exemple suivant, nous ne voulons exécuter la règle <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> que si l'URI demandé ne
correspond pas à un fichier existant.</p>
<pre class="prettyprint lang-config"># La requête concerne-t-elle un fichier qui n'existe pas ?
RewriteCond "%{REQUEST_FILENAME}" "!-f"
RewriteCond "%{REQUEST_FILENAME}" "!-d"
# Si c'est la cas, on saute les deux règles de réécriture suivantes
RewriteRule ".?" "-" [S=2]

RewriteRule "(.*\.gif)" "images.php?$1"
RewriteRule "(.*\.html)" "docs.php?$1"</pre>




<p>Cette technique trouve son utilité dans le fait qu'une directive
<code class="directive"><a href="../mod/mod_rewrite.html#rewritecond">RewriteCond</a></code> ne s'applique
qu'à la règle qui la suit immédiatement. Ainsi, si vous voulez
qu'une directive <code>RewriteCond</code> s'applique à plusieurs règles
<code>RewriteRule</code>, une technique possible consiste à inverser ces
conditions et ajouter une <code>RewriteRule</code> avec le drapeau [Skip]. Cette technique permet
d'élaborer des pseudo-constructions if-then-else : la dernière règle du
bloc then contiendra <code>skip=N</code>, où N est le nombre de règles
contenues dans le bloc else :</p>
<pre class="prettyprint lang-config"># Est-ce que le fichier existe ?
RewriteCond "%{REQUEST_FILENAME}" "!-f"
RewriteCond "%{REQUEST_FILENAME}" "!-d"
# Create an if-then-else construct by skipping 3 lines if we meant to go to the "else" stanza.
RewriteRule ".?" "-" [S=3]

# Si le fichier existe, alors :
RewriteRule "(.*\.gif)" "images.php?$1"
    RewriteRule "(.*\.html)" "docs.php?$1"
    # Skip past the "else" stanza.
    RewriteRule ".?" "-" [S=1]
# ELSE...
RewriteRule "(.*)" "404.php?file=$1
# END</pre>


<p>Il est probablement plus aisé de définir ce genre de configuration
via les directives <code class="directive">&lt;If&gt;</code>, <code class="directive">&lt;ElseIf&gt;</code>, et <code class="directive">&lt;Else&gt;</code>.</p>

</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="flag_t" id="flag_t">T|type</a></h2>
<p>Définit le type MIME de la réponse résultante renvoyée. L'effet est
identique à celui de la directive <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code>.</p>

<p>Par exemple, vous pouvez utiliser la technique suivante pour servir
du code source Perl en tant que plein texte, s'il est requis d'une
certaine manière :</p>

<pre class="prettyprint lang-config"># Sert les fichier .pl en tant que plein texte
RewriteRule "\.pl$" "-" [T=text/plain]</pre>


<p>Ou encore, si vous possédez une caméra qui produit des fichiers
images jpeg sans extension, vous pouvez forcer le renvoi de ces images
avec le type MIME correct en se basant sur le nom du fichier :</p>

<pre class="prettyprint lang-config"># Les fichiers dont le nom contient 'IMG' sont des images jpg.
RewriteRule "IMG" "-" [T=image/jpg]</pre>


<p>Notez cependant qu'il s'agit d'un exemple trivial, et que le problème
aurait pu être résolu en utilisant à la place la directive <code class="directive"><a href="../mod/core.html#filesmatch">&lt;FilesMatch&gt;</a></code>. Il faut toujours
envisager la possibilité d'une solution alternative à un problème avant
d'avoir recours à la réécriture, qui sera toujours moins efficace qu'une
solution alternative.</p>

<p>
Dans un contexte de niveau répertoire, n'utilisez que <code>-</code>
(tiret) comme substitution, <em>dans toute la séquence de réécriture de
mod_rewrite</em>, sinon le type MIME défini avec ce drapeau
sera perdu suite à un retraitement interne (y compris les séquences de
réécriture suivantes de mod_rewrite). Dans ce contexte, vous pouvez
utiliser le drapeau <code>L</code> pour terminer la séquence
<em>courante</em> de réécriture de mod_rewrite.</p>

       <p><code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> permet de modifier les requêtes
       entrantes dynamiquement, en fonction de règles manipulant des <a href="intro.html#regex">expressions rationnelles</a>. Vous pouvez
       ainsi relier des URLs arbitraires à votre propre structure d'URLs
       interne comme vous le souhaitez.</p>

      <p>Il fournit un
      mécanisme de manipulation d'URL particulièrement souple et
      puissant en supportant un nombre illimité de règles et de
      conditions attachées à chaque règle. Les manipulations d'URLs
      peuvent dépendre de tests variés : les URLs peuvent
      être finement caractérisées en fonction de variables du serveur,
      de variables d'environnement, d'en-têtes HTTP, de repères
      temporels, de recherches dans des bases de données
      externes, ou même de requêtes vers des bases de données externes
      et de différents gestionnaires ou programmes externes.</p>

      <p>Les règles de réécriture peuvent agir sur l'ensemble des URLs (la partie chemin
      et la chaîne de paramètres) et peuvent être utilisées dans le contexte du serveur principal
      (<code>httpd.conf</code>), mais aussi dans le contexte des
      serveurs virtuels (sections <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>), ou dans le
      contexte des
      répertoires (fichiers <code>.htaccess</code> et blocs
      <code>&lt;Directory&gt;</code>. Le résultat
      réécrit peut conduire vers d'autres règles à un
      traitement secondaire interne, une redirection vers une requête
      externe ou même l'envoi vers un serveur mandataire, en fonction
      des  <a href="flags.html">drapeaux</a> que vous attachez aux
      règles</p>

	<p>mod_rewrite étant très puissant, il peut par
	conséquent être très complexe. Ce document
	complète la <a href="../mod/mod_rewrite.html">documentation de
      référence du module mod_rewrite</a>, et est sensé alléger un
      peu cette complexité, et présenter des exemples largement
      commentés, ainsi que des situations courantes que vous
      pourrez traiter avec mod_rewrite. Mais nous voulons aussi vous
      montrer des situations où vous ne devrez pas utiliser
      mod_rewrite, et lui préférer d'autres
      fonctionnalités standard d'Apache, évitant ainsi
      d'entrer dans une complexité inutile.</p>

    <p>When using any of the threaded mpms in the Apache HTTP Server 2.x it is important
    that every function called from Apache be thread safe.  When linking in 3rd
    party extensions it can be difficult to determine whether the resulting
    server will be thread safe.  Casual testing generally won't tell you this
    either as thread safety problems can lead to subtle race conditions that
    may only show up in certain conditions under heavy load.</p>

<h2><a name="variables" id="variables">Global and static variables</a></h2>
    <p>When writing your module or when trying to determine if a module or
    3rd party library is thread safe there are some common things to keep in
    mind.</p>

    <p>First, you need to recognize that in a threaded model each individual
    thread has its own program counter, stack and registers.  Local variables
    live on the stack, so those are fine.  You need to watch out for any
    static or global variables.  This doesn't mean that you are absolutely not
    allowed to use static or global variables.  There are times when you
    actually want something to affect all threads, but generally you need to
    avoid using them if you want your code to be thread safe.</p>

    <p>In the case where you have a global variable that needs to be global and
    accessed by all threads, be very careful when you update it.  If, for
    example, it is an incrementing counter, you need to atomically increment
    it to avoid race conditions with other threads.  You do this using a mutex
    (mutual exclusion). Lock the mutex, read the current value, increment it
    and write it back and then unlock the mutex.  Any other thread that wants
    to modify the value has to first check the mutex and block until it is
    cleared.</p>

    <p>If you are using <a href="http://apr.apache.org/">APR</a>, have a look
    at the <code>apr_atomic_<var>*</var></code> functions and the
    <code>apr_thread_mutex_<var>*</var></code> functions.</p>
    
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="errno" id="errno">errno</a></h2>
    <p>This is a common global variable that holds the error number of the
    last error that occurred. If one thread calls a low-level function that
    sets errno and then another thread checks it, we are bleeding error
    numbers from one thread into another.  To solve this, make sure your
    module or library defines <code>_REENTRANT</code> or is compiled with
    <code>-D_REENTRANT</code>. This will make errno a per-thread variable
    and should hopefully be transparent to the code. It does this by doing
    something like this:</p>

    <div class="example"><p><code>
      #define errno (*(__errno_location()))
    </code></p></div>

    <p>which means that accessing errno will call
    <code>__errno_location()</code> which is provided by the libc. Setting
    <code>_REENTRANT</code> also forces redefinition of some other functions
    to their <code><var>*</var>_r</code> equivalents and sometimes changes
    the common <code>getc</code>/<code>putc</code> macros into safer function
    calls.  Check your libc documentation for specifics.  Instead of, or in
    addition to <code>_REENTRANT</code> the symbols that may affect this are
    <code>_POSIX_C_SOURCE</code>, <code>_THREAD_SAFE</code>,
    <code>_SVID_SOURCE</code>, and <code>_BSD_SOURCE</code>.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="functions" id="functions">Common standard troublesome functions</a></h2>
    <p>Not only do things have to be thread safe, but they also have to be
    reentrant. <code>strtok()</code> is an obvious one. You call it the first
    time with your delimiter which it then remembers and on each subsequent
    call it returns the next token.  Obviously if multiple threads are
    calling it you will have a problem.  Most systems have a reentrant version
    of the function called <code>strtok_r()</code> where you pass in an
    extra argument which contains an allocated <code>char *</code> which the
    function will use instead of its own static storage for maintaining
    the tokenizing state. If you are using <a href="http://apr.apache.org/">APR</a> you can use <code>apr_strtok()</code>.</p>

    <p><code>crypt()</code> is another function that tends to not be reentrant,
    so if you run across calls to that function in a library, watch out. On
    some systems it is reentrant though, so it is not always a problem. If
    your system has <code>crypt_r()</code> chances are you should be using
    that, or if possible simply avoid the whole mess by using md5 instead.</p>

<div class="section">
<h2><a name="commonlibs" id="commonlibs">Common 3rd Party Libraries</a></h2>
    <p>The following is a list of common libraries that are used by 3rd party
    Apache modules.  You can check to see if your module is using a potentially
    unsafe library by using tools such as <code>ldd(1)</code> and
    <code>nm(1)</code>. For <a href="http://www.php.net/">PHP</a>, for example,
    try this:</p>

    <div class="example"><p><code>

      libsnmp.so.0 =&gt; /usr/lib/libsnmp.so.0 (0x402f9000)<br />
      libpdf.so.1 =&gt; /usr/local/lib/libpdf.so.1 (0x40353000)<br />

      libjpeg.so.62 =&gt; /usr/lib/libjpeg.so.62 (0x404e7000)<br />
      libcrypt.so.1 =&gt; /lib/libcrypt.so.1 (0x40505000)<br />
      libssl.so.2 =&gt; /lib/libssl.so.2 (0x40532000)<br />
      libcrypto.so.2 =&gt; /lib/libcrypto.so.2 (0x40560000)<br />
      libresolv.so.2 =&gt; /lib/libresolv.so.2 (0x40624000)<br />
      libdl.so.2 =&gt; /lib/libdl.so.2 (0x40634000)<br />

      /lib/ld-linux.so.2 =&gt; /lib/ld-linux.so.2 (0x80000000)
    </code></p></div>

    <p>In addition to these libraries you will need to have a look at any
    libraries linked statically into the module. You can use <code>nm(1)</code>
    to look for individual symbols in the module.</p>

<h2><a name="easy" id="easy">簡単な変更点</a></h2>

    <h3><a name="cleanup" id="cleanup">クリーンナップ ルーチン</a></h3>
      <p>クリーンナップルーチンは <code>apr_status_t</code> 型である必要があります。
      そして、apr_status_t 型の値を返さなくてはなりません。
      クリーンナップ中のエラーを通知する必要がなければ、返り値は普通、
      <code>ARP_SUCCESS</code> です。たとえエラーを通知したとしても、
      すべてのコードがその通知をチェックしたり、
      エラーに応じた動作をするわけではないことに気をつけてください。</p>
    


    <h3><a name="init" id="init">初期化ルーチン</a></h3>

    <p>初期化ルーチンは処理全体から見てしっくりくるような意味を表すように、
    名前が変更されました。ですから、<code>mmap_init</code> から <code>mmap_post_config</code>
    のようにちょっと変更されました。
    渡される引数は大幅に変更され、次のようになりました。</p>

      <ul>
        <li><code>apr_pool_t *p</code></li>
        <li><code>apr_pool_t *plog</code></li>

      <p>データ型のほとんどは <a href="http://apr.apache.org/">APR</a> に移されました。つまり、
      いくつかの名前が前述のように変更されています。
      施すべき変更点の簡単な一覧を以下に示します。</p>

      <ul>
        <li><code>pool</code> becomes <code>apr_pool_t</code></li>
        <li><code>table</code> becomes <code>apr_table_t</code></li>

<h2><a name="messy" id="messy">もっと厄介な変更点…</a></h2>

    <h3><a name="register-hooks" id="register-hooks">フックの登録</a></h3>
      <p>新しいアーキテクチャでは作成した関数を呼び出すのに
      一連のフックを使用します。このフックは、新しい関数
      <code>static void register_hooks(void)</code> を使って登録するよう、
      モジュールに書き足さなくてはなりません。
      この関数は、なにをすべきか一旦理解してしまえば、
      十分にわかりやすいものです。
      リクエストの処理のあるステージで呼び出さなくてはならない
      関数は登録する必要があります。ハンドラは登録する必要はありません。
      関数を登録できるフェーズはたくさんあります。
      それぞれのフェーズで、関数を呼び出す相対的な順番は、
      かなりの程度制御できます。</p>

    <p>以下は、<code>mod_mmap_static</code> に追加したコードです:</p>

      <div class="example"><pre>static void register_hooks(void)
{
    static const char * const aszPre[]={ "http_core.c",NULL };
    ap_hook_post_config(mmap_post_config,NULL,NULL,HOOK_MIDDLE);
    ap_hook_translate_name(mmap_static_xlat,aszPre,NULL,HOOK_LAST);
};</pre></div>

    <p>ここでは呼びだすべき二つの関数を登録しています。一つは
    <code>post_config</code> ステージ用 (ほとんどすべてのモジュール
    はこれが必要です) で、もう一つは <code>translate_name</code> フェーズ用です。
    それぞれの関数は名前は違うけれども形式は同じであることに注意してください。
    それでは、形式はどのようになっているでしょうか?</p>

      <div class="example"><p><code>
        ap_hook_<var>phase_name</var>(<var>function_name</var>,
        <var>predecessors</var>, <var>successors</var>, <var>position</var>);
      </code></p></div>

    <p>三つの位置が定義されています…</p>

      <ul>
        <li><code>HOOK_FIRST</code></li>
        <li><code>HOOK_MIDDLE</code></li>
        <li><code>HOOK_LAST</code></li>
      </ul>

    <p>位置を定義するには、上記の「位置」を指定し、
    修飾子である「先行」と「後行」で手を加えます。
   「先行」「後行」は、呼ばれるべき関数のリストです。
   「先行」は関数の実行前に呼ばれるもので、
   「後行」は実行後に呼ばれるものです。</p>

    <p><code>mod_mmap_static</code> の場合、<code>post_config</code>
    ステージでは必要ありませんが、
    <code>mmap_static_xlat</code> が core モジュールが名前の変換を実行した後に
    <strong>呼ばれなければなりません</strong>。
    そこで aszPre を使って <code>HOOK_LAST</code> の修飾子を定義しています。</p>
  

    <h3><a name="moddef" id="moddef">モジュールの定義</a></h3>
      <p>モジュールの定義を作成する際に注意しなければならない
      ステージの数は激減しています。古い定義は次のようになっていました。</p>

      <div class="example"><pre>module MODULE_VAR_EXPORT <var>module_name</var>_module =
{
    STANDARD_MODULE_STUFF,
    /* initializer */
    /* dir config creater */
    /* dir merger --- default is to override */
    /* server config */
    /* merge server config */
    /* command handlers */
    /* handlers */
    /* filename translation */
    /* check_user_id */
    /* check auth */
    /* check access */
    /* type_checker */
    /* fixups */
    /* logger */
    /* header parser */
    /* child_init */
    /* child_exit */
    /* post read-request */
};</pre></div>

    <p>新しい構造体はとってもシンプルです…</p>
      <div class="example"><pre>module MODULE_VAR_EXPORT <var>module_name</var>_module =
{
    STANDARD20_MODULE_STUFF,
    /* create per-directory config structures */
    /* merge per-directory config structures  */
    /* create per-server config structures    */
    /* merge per-server config structures     */
    /* command handlers */
    /* handlers */
    /* register hooks */
};</pre></div>

    <p>このうちのいくつかは古いものから新しいものに直接読み替えられるもので、
    いくつかはそうではありません。どうすればいいのかを要約してみます。</p>

    <p>直接読み替えられるステージ:</p>

    <dl>
      <dt><code>/* ディレクトリ設定作成関数 */</code></dt>
      <dd><code>/* ディレクトリ毎設定構造体作成 */</code></dd>

      <dt><code>/* サーバ設定作成関数 */</code></dt>
      <dd><code>/* サーバ毎設定構造体作成 */</code></dd>

      <dt><code>/* サーバ設定マージ関数 */</code></dt>
      <dd><code>/* サーバ毎設定構造体作成マージ */</code></dd>

      <dt><code>/* コマンド・テーブル */</code></dt>
      <dd><code>/* コマンド apr_table_t */</code></dd>

      <dt><code>/* ハンドラ */</code></dt>
      <dd><code>/* ハンドラ */</code></dd>
    </dl>

    <p>古い関数の残りのものはフックとして登録されるべきです。
    現時点で次のようなフック・ステージが定義されています…</p>

<h2><a name="types" id="types">Filter Types</a></h2>
    <p>There are three basic filter types (each of these is actually broken
    down into two categories, but that comes later).</p>

    <dl>
    <dt><code>CONNECTION</code></dt>
    <dd>Filters of this type are valid for the lifetime of this connection.
    (<code>AP_FTYPE_CONNECTION</code>, <code>AP_FTYPE_NETWORK</code>)</dd>

    <dt><code>PROTOCOL</code></dt>
    <dd>Filters of this type are valid for the lifetime of this request from
    the point of view of the client, this means that the request is valid
    from the time that the request is sent until the time that the response
    is received. (<code>AP_FTYPE_PROTOCOL</code>,
    <code>AP_FTYPE_TRANSCODE</code>)</dd>

    <dt><code>RESOURCE</code></dt>
    <dd>Filters of this type are valid for the time that this content is used
    to satisfy a request.  For simple requests, this is identical to
    <code>PROTOCOL</code>, but internal redirects and sub-requests can change
    the content without ending the request. (<code>AP_FTYPE_RESOURCE</code>,
    <code>AP_FTYPE_CONTENT_SET</code>)</dd>
    </dl>

    <p>It is important to make the distinction between a protocol and a
    resource filter.  A resource filter is tied to a specific resource, it
    may also be tied to header information, but the main binding is to a
    resource.  If you are writing a filter and you want to know if it is
    resource or protocol, the correct question to ask is:  "Can this filter
    be removed if the request is redirected to a different resource?"  If
    the answer is yes, then it is a resource filter.  If it is no, then it
    is most likely a protocol or connection filter.  I won't go into
    connection filters, because they seem to be well understood. With this
    definition, a few examples might help:</p>

    <dl>
    <dt>Byterange</dt>
    <dd>We have coded it to be inserted for all requests, and it is removed
    if not used.  Because this filter is active at the beginning of all
    requests, it can not be removed if it is redirected, so this is a
    protocol filter.</dd>

    <dt>http_header</dt>
    <dd>This filter actually writes the headers to the network.  This is
    obviously a required filter (except in the asis case which is special
    and will be dealt with below) and so it is a protocol filter.</dd>

    <dt>Deflate</dt>
    <dd>The administrator configures this filter based on which file has been
    requested.  If we do an internal redirect from an autoindex page to an
    index.html page, the deflate filter may be added or removed based on
    config, so this is a resource filter.</dd>
    </dl>

    <p>The further breakdown of each category into two more filter types is
    strictly for ordering.  We could remove it, and only allow for one
    filter type, but the order would tend to be wrong, and we would need to
    hack things to make it work.  Currently, the <code>RESOURCE</code> filters
    only have one filter type, but that should change.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="howinserted" id="howinserted">How are filters inserted?</a></h2>
    <p>This is actually rather simple in theory, but the code is
    complex.  First of all, it is important that everybody realize that
    there are three filter lists for each request, but they are all
    concatenated together:</p>
    <ul>
        <li><code>r-&gt;output_filters</code> (corresponds to RESOURCE)</li>
        <li><code>r-&gt;proto_output_filters</code> (corresponds to PROTOCOL)</li>
        <li><code>r-&gt;connection-&gt;output_filters</code> (corresponds to CONNECTION)</li>
    </ul> 
    
    <p>The problem previously, was that we used a singly linked list to create the filter stack, and we
    started from the "correct" location.  This means that if I had a
    <code>RESOURCE</code> filter on the stack, and I added a
    <code>CONNECTION</code> filter, the <code>CONNECTION</code> filter would
    be ignored. This should make sense, because we would insert the connection
    filter at the top of the <code>c-&gt;output_filters</code> list, but the end
    of <code>r-&gt;output_filters</code> pointed to the filter that used to be
    at the front of <code>c-&gt;output_filters</code>. This is obviously wrong.
    The new insertion code uses a doubly linked list. This has the advantage
    that we never lose a filter that has been inserted. Unfortunately, it comes
    with a separate set of headaches.</p>

    <p>The problem is that we have two different cases were we use subrequests.
    The first is to insert more data into a response. The second is to
    replace the existing response with an internal redirect. These are two
    different cases and need to be treated as such.</p>

    <p>In the first case, we are creating the subrequest from within a handler
    or filter.  This means that the next filter should be passed to
    <code>make_sub_request</code> function, and the last resource filter in the
    sub-request will point to the next filter in the main request.  This
    makes sense, because the sub-request's data needs to flow through the
    same set of filters as the main request.  A graphical representation
    might help:</p>

<div class="example"><pre>Default_handler --&gt; includes_filter --&gt; byterange --&gt; ...</pre></div>

    <p>If the includes filter creates a sub request, then we don't want the
    data from that sub-request to go through the includes filter, because it
    might not be SSI data.  So, the subrequest adds the following:</p>

<div class="example"><pre>Default_handler --&gt; includes_filter -/-&gt; byterange --&gt; ...
                                    /
Default_handler --&gt; sub_request_core</pre></div>

    <p>What happens if the subrequest is SSI data?  Well, that's easy, the
    <code>includes_filter</code> is a resource filter, so it will be added to
    the sub request in between the <code>Default_handler</code> and the
    <code>sub_request_core</code> filter.</p>

    <p>The second case for sub-requests is when one sub-request is going to
    become the real request.  This happens whenever a sub-request is created
    outside of a handler or filter, and NULL is passed as the next filter to
    the <code>make_sub_request</code> function.</p>

    <p>In this case, the resource filters no longer make sense for the new
    request, because the resource has changed.  So, instead of starting from
    scratch, we simply point the front of the resource filters for the
    sub-request to the front of the protocol filters for the old request.
    This means that we won't lose any of the protocol filters, neither will
    we try to send this data through a filter that shouldn't see it.</p>

    <p>The problem is that we are using a doubly-linked list for our filter
    stacks now. But, you should notice that it is possible for two lists to
    intersect in this model.  So, you do you handle the previous pointer?
    This is a very difficult question to answer, because there is no "right"
    answer, either method is equally valid.  I looked at why we use the
    previous pointer.  The only reason for it is to allow for easier
    addition of new servers.  With that being said, the solution I chose was
    to make the previous pointer always stay on the original request.</p>

    <p>This causes some more complex logic, but it works for all cases.  My
    concern in having it move to the sub-request, is that for the more
    common case (where a sub-request is used to add data to a response), the
    main filter chain would be wrong.  That didn't seem like a good idea to
    me.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="asis" id="asis">Asis</a></h2>
    <p>The final topic.  :-)  Mod_Asis is a bit of a hack, but the
    handler needs to remove all filters except for connection filters, and
    send the data.  If you are using <code class="module"><a href="../mod/mod_asis.html">mod_asis</a></code>, all other
    bets are off.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="conclusion" id="conclusion">Explanations</a></h2>
    <p>The absolutely last point is that the reason this code was so hard to
    get right, was because we had hacked so much to force it to work.  I
    wrote most of the hacks originally, so I am very much to blame.
    However, now that the code is right, I have started to remove some
    hacks.  Most people should have seen that the <code>reset_filters</code>
    and <code>add_required_filters</code> functions are gone.  Those inserted
    protocol level filters for error conditions, in fact, both functions did
    the same thing, one after the other, it was really strange. Because we
    don't lose protocol filters for error cases any more, those hacks went away.
    The <code>HTTP_HEADER</code>, <code>Content-length</code>, and
    <code>Byterange</code> filters are all added in the
    <code>insert_filters</code> phase, because if they were added earlier, we
    had some interesting interactions.  Now, those could all be moved to be
    inserted with the <code>HTTP_IN</code>, <code>CORE</code>, and
    <code>CORE_IN</code> filters.  That would make the code easier to
    follow.</p>

  <p>This document describes changes to the Apache HTTPD API from
     version 2.2 to 2.4, that may be of interest to module/application
     developers and core hacks.  As of the first GA release of the
     2.4 branch API compatibility is preserved for the life of the
     2.4 branch.  (The
     <a href="http://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x/VERSIONING">VERSIONING</a>
     description for the 2.4 release provides more information about API
     compatibility.)</p>

  <p>API changes fall into two categories: APIs that are altogether new,
     and existing APIs that are expanded or changed.  The latter are
     further divided into those where all changes are backwards-compatible
     (so existing modules can ignore them), and those that might
     require attention by maintainers.  As with the transition from
     HTTPD 2.0 to 2.2, existing modules and applications will require
     recompiling and may call for some attention, but most should not
     require any substantial updating (although some may be able to
     take advantage of API changes to offer significant improvements).</p>
  <p>For the purpose of this document, the API is split according
     to the public header files.  These headers are themselves the
     reference documentation, and can be used to generate a browsable
     HTML reference with <code>make docs</code>.</p>

<h2><a name="api_changes" id="api_changes">Changed APIs</a></h2>
  

  <h3><a name="ap_expr" id="ap_expr">ap_expr (NEW!)</a></h3>
    
    <p>Introduces a new API to parse and evaluate boolean and algebraic
       expressions, including provision for a standard syntax and
       customised variants.</p>
  

  <h3><a name="ap_listen" id="ap_listen">ap_listen (changed; backwards-compatible)</a></h3>
    
    <p>Introduces a new API to enable httpd child processes to serve
       different purposes.</p>
  

  <h3><a name="ap_mpm" id="ap_mpm">ap_mpm (changed)</a></h3>
    
  <p><code>ap_mpm_run</code> is replaced by a new <code>mpm</code> hook.
  Also <code>ap_graceful_stop_signalled</code> is lost, and
  <code>ap_mpm_register_timed_callback</code> is new.</p>
  

  <h3><a name="ap_regex" id="ap_regex">ap_regex (changed)</a></h3>
    
  <p>In addition to the existing regexp wrapper, a new higher-level API
  <code>ap_rxplus</code> is now provided.  This provides the capability to
  compile Perl-style expressions like <code>s/regexp/replacement/flags</code>
  and to execute them against arbitrary strings. Support for regexp
  backreferences is also added.</p>
  

  <h3><a name="ap_slotmem" id="ap_slotmem">ap_slotmem (NEW!)</a></h3>
    
    <p>Introduces an API for modules to allocate and manage memory slots,
    most commonly for shared memory.</p>
  

  <h3><a name="ap_socache" id="ap_socache">ap_socache (NEW!)</a></h3>
    
    <p>API to manage a shared object cache.</p>
  

  <h3><a name="heartbeat" id="heartbeat">heartbeat (NEW!)</a></h3>
    
    <p>common structures for heartbeat modules</p>
  

  <h3><a name="ap_parse_htaccess" id="ap_parse_htaccess">ap_parse_htaccess (changed)</a></h3>
    
    <p>The function signature for <code>ap_parse_htaccess</code> has been
    changed. A <code>apr_table_t</code> of individual directives allowed
    for override must now be passed (override remains).</p>
  

  <h3><a name="http_config" id="http_config">http_config (changed)</a></h3>
    
    <ul>
      <li>Introduces per-module, per-directory loglevels, including macro wrappers.</li>
      <li>New <code>AP_DECLARE_MODULE</code> macro to declare all modules.</li>
      <li>New <code>APLOG_USE_MODULE</code> macro necessary for per-module loglevels in
          multi-file modules.</li>
      <li>New API to retain data across module unload/load</li>
      <li>New <code>check_config</code> hook</li>
      <li>New <code>ap_process_fnmatch_configs()</code> function to process wildcards</li>
      <li>Change <code>ap_configfile_t</code>, <code>ap_cfg_getline()</code>,
          <code>ap_cfg_getc()</code> to return error codes, and add
          <code>ap_pcfg_strerror()</code> for retrieving an error description.</li>
      <li>Any config directive permitted in ACCESS_CONF context must now
          correctly handle being called from an .htaccess file via the new
          <code class="directive"><a href="../mod/core.html#allowoverridelist">AllowOverrideList</a></code> directive.
          ap_check_cmd_context() accepts a new flag NOT_IN_HTACCESS to detect
          this case.</li>
    </ul>
  

  <h3><a name="http_core" id="http_core">http_core (changed)</a></h3>
    
    <ul>
      <li>REMOVED <code>ap_default_type</code>, <code>ap_requires</code>, all
          2.2 authnz API</li>
      <li>Introduces Optional Functions for logio and authnz</li>
      <li>New function <code>ap_get_server_name_for_url</code> to support IPv6
          literals.</li>
      <li>New function <code>ap_register_errorlog_handler</code> to register error log
          format string handlers.</li>
      <li>Arguments of <code>error_log</code> hook have changed. Declaration has moved to
          <code>http_core.h</code>.</li>
      <li>New function <code>ap_state_query</code> to determine if the server is in the
          initial configuration preflight phase or not. This is both easier to
          use and more correct than the old method of creating a pool userdata
          entry in the process pool.</li>
      <li>New function <code>ap_get_conn_socket</code> to get the socket descriptor for a
          connection. This should be used instead of accessing the core
          connection config directly.</li>
    </ul>
  

  <h3><a name="httpd" id="httpd">httpd (changed)</a></h3>
    
    <ul>

      <li>Modules that load other modules later than the <code>EXEC_ON_READ</code> config
          reading stage need to call <code>ap_reserve_module_slots()</code> or
          <code>ap_reserve_module_slots_directive()</code> in their
          <code>pre_config hook</code>.</li>
      <li>The useragent IP address per request can now be tracked
          independently of the client IP address of the connection, for
          support of deployments with load balancers.</li>
    </ul>
  

  <h3><a name="http_log" id="http_log">http_log (changed)</a></h3>
    
    <ul>
      <li>Introduce per-directory, per-module loglevel</li>
      <li>New loglevels <code>APLOG_TRACEn</code></li>
      <li><code>ap_log_*error</code> become macro wrappers (backwards-compatible if
          <code>APLOG_MARK</code> macro is used, except that is no longer possible to

      <li><code>module_index</code> added to error_log hook</li>
      <li>new function: <code>ap_log_command_line</code></li>
    </ul>
  

  <h3><a name="http_request" id="http_request">http_request (changed)</a></h3>
    
    <ul>
      <li>New auth_internal API and auth_provider API</li>
      <li>New <code>EOR</code> bucket type</li>
      <li>New function <code>ap_process_async_request</code></li>
      <li>New flags <code>AP_AUTH_INTERNAL_PER_CONF</code> and
          <code>AP_AUTH_INTERNAL_PER_URI</code></li>
      <li>New <code>access_checker_ex</code> hook to apply additional access control
          and/or bypass authentication.</li>
      <li>New functions <code>ap_hook_check_access_ex</code>,
          <code>ap_hook_check_access</code>, <code>ap_hook_check_authn</code>,
          <code>ap_hook_check_authz</code> which accept
          <code>AP_AUTH_INTERNAL_PER_*</code> flags</li>
      <li>DEPRECATED direct use of <code>ap_hook_access_checker</code>,
          <code>access_checker_ex</code>, <code>ap_hook_check_user_id</code>,
          <code>ap_hook_auth_checker</code></li>
    </ul>
    <p>When possible, registering all access control hooks (including
       authentication and authorization hooks) using <code>AP_AUTH_INTERNAL_PER_CONF</code>
       is recommended.  If all modules' access control hooks are registered
       with this flag, then whenever the server handles an internal
       sub-request that matches the same set of access control configuration
       directives as the initial request (which is the common case), it can
       avoid invoking the access control hooks another time.</p>
    <p>If your module requires the old behavior and must perform access
       control checks on every sub-request with a different URI from the
       initial request, even if that URI matches the same set of access
       control configuration directives, then use
       <code>AP_AUTH_INTERNAL_PER_URI</code>.</p>
  

  <h3><a name="mod_auth" id="mod_auth">mod_auth (NEW!)</a></h3>
    
    <p>Introduces the new provider framework for authn and authz</p>
  

  <h3><a name="mod_cache" id="mod_cache">mod_cache (changed)</a></h3>
    
    <p>Introduces a <code>commit_entity()</code> function to the cache provider
    interface, allowing atomic writes to cache. Add a <code>cache_status()</code>
    hook to report the cache decision. All private structures and functions were
    removed.</p>
  

  <h3><a name="mod_core" id="mod_core">mod_core (NEW!)</a></h3>
    
    <p>This introduces low-level APIs to send arbitrary headers,
    and exposes functions to handle HTTP OPTIONS and TRACE.</p>
  

  <h3><a name="mod_cache_disk" id="mod_cache_disk">mod_cache_disk (changed)</a></h3>
    
    <p>Changes the disk format of the disk cache to support atomic cache
    updates without locking. The device/inode pair of the body file is
    embedded in the header file, allowing confirmation that the header
    and body belong to one another.</p>
  

  <h3><a name="mod_disk_cache" id="mod_disk_cache">mod_disk_cache (renamed)</a></h3>
    
    <p>The mod_disk_cache module has been renamed to mod_cache_disk in
    order to be consistent with the naming of other modules within the
    server.</p>
  

  <h3><a name="mod_request" id="mod_request">mod_request (NEW!)</a></h3>
    
    <p>The API for <code class="module"><a href="../mod/mod_request.html">mod_request</a></code>, to make input data
    available to multiple application/handler modules where required,
    and to parse HTML form data.</p>
  

  <h3><a name="mpm_common" id="mpm_common">mpm_common (changed)</a></h3>
    
    <ul>
      <li>REMOVES: <code>accept</code>, <code>lockfile</code>, <code>lock_mech</code>,
          <code>set_scoreboard</code> (locking uses the new ap_mutex API)</li>
      <li>NEW API to drop privileges (delegates this platform-dependent
          function to modules)</li>
      <li>NEW Hooks: <code>mpm_query</code>, <code>timed_callback</code>, and
          <code>get_name</code></li>
      <li>CHANGED interfaces: <code>monitor</code> hook,
          <code>ap_reclaim_child_processes</code>,
          <code>ap_relieve_child_processes</code></li>
    </ul>
  

  <h3><a name="scoreboard" id="scoreboard">scoreboard (changed)</a></h3>
    
    <p><code>ap_get_scoreboard_worker</code> is made non-backwards-compatible
    as an alternative version is introduced.  Additional proxy_balancer
    support.  Child status stuff revamped.</p>

<h2><a name="upgrading" id="upgrading">Specific information on upgrading modules from 2.2</a></h2>
  

  <h3><a name="upgrading_logging" id="upgrading_logging">Logging</a></h3>
    
    <p>In order to take advantage of per-module loglevel configuration, any
       source file that calls the <code>ap_log_*</code> functions should declare
       which module it belongs to. If the module's module_struct is called
       <code>foo_module</code>, the following code can be used to remain
       backward compatible with HTTPD 2.0 and 2.2:</p>
    <div class="example"><p><code>
        #include &lt;http_log.h&gt;<br />
        <br />
        #ifdef APLOG_USE_MODULE<br />
        APLOG_USE_MODULE(foo);<br />
        #endif
    </code></p></div>
    <p>Note: This is absolutely required for C++-language modules.  It
    can be skipped for C-language modules, though that breaks
    module-specific log level support for files without it.</p>
    <p>The number of parameters of the <code>ap_log_*</code> functions and the
       definition of <code>APLOG_MARK</code> has changed. Normally, the change
       is completely transparent. However, changes are required if a
       module uses <code>APLOG_MARK</code> as a parameter to its own functions
       or if a module calls <code>ap_log_*</code> without passing
       <code>APLOG_MARK</code>.  A module which uses wrappers
       around <code>ap_log_*</code> typically uses both of these constructs.</p>

    <p>The easiest way to change code which passes <code>APLOG_MARK</code> to
       its own functions is to define and use a different macro that expands to
       the parameters required by those functions, as <code>APLOG_MARK</code>
       should only be used when calling <code>ap_log_*</code>
       directly.  In this way, the code will remain compatible with HTTPD 2.0
       and 2.2.</p>

    <p>Code which calls <code>ap_log_*</code> without passing
       <code>APLOG_MARK</code> will necessarily differ between 2.4 and earlier
       releases, as 2.4 requires a new third argument,
       <code>APLOG_MODULE_INDEX</code>.</p>

    <div class="example"><p><code>
       /* code for httpd 2.0/2.2 */<br />
       ap_log_perror(file, line, APLOG_ERR, 0, p, "Failed to allocate dynamic lock structure");<br />
       <br />
       /* code for httpd 2.4 */<br />
       ap_log_perror(file, line, APLOG_MODULE_INDEX, APLOG_ERR, 0, p, "Failed to allocate dynamic lock structure");<br />
       <br />
    </code></p></div>

    <p><code>ap_log_*error</code> are now implemented as macros. This means
       that it is no longer possible to use <code>#ifdef</code> inside the
       argument list of <code>ap_log_*error</code>, as this would cause
       undefined behavior according to C99.</p>

    <p>A <code>server_rec</code> pointer must be passed to
       <code>ap_log_error()</code> when called after startup.  This
       was always appropriate, but there are even more limitations with
       a <code>NULL</code> <code>server_rec</code> in 2.4 than in
       previous releases.  Beginning with 2.3.12, the global variable
       <code>ap_server_conf</code> can always be used as
       the <code>server_rec</code> parameter, as it will be
       <code>NULL</code> only when it is valid to pass <code>NULL</code>
       to <code>ap_log_error()</code>.  <code>ap_server_conf</code>
       should be used only when a more appropriate <code>server_rec</code>
       is not available.</p>

    <p>Consider the following changes to take advantage of the new
       <code>APLOG_TRACE1..8</code> log levels:</p>
       <ul>
         <li>Check current use of <code>APLOG_DEBUG</code> and
         consider if one of the <code>APLOG_TRACEn</code> levels is
         more appropriate.</li>
         <li>If your module currently has a mechanism for configuring
         the amount of debug logging which is performed, consider
         eliminating that mechanism and relying on the use of
         different <code>APLOG_TRACEn</code> levels.  If expensive
         trace processing needs to be bypassed depending on the
         configured log level, use the <code>APLOGtrace<em>n</em></code>
         and <code>APLOGrtrace<em>n</em></code> macros to first check
         if tracing is enabled.</li>
       </ul>

    <p>Modules sometimes add process id and/or thread id to their log
       messages.  These ids are now logged by default, so it may not
       be necessary for the module to log them explicitly.  (Users may
       remove them from the error log format, but they can be
       instructed to add it back if necessary for problem diagnosis.)</p>

      <dd>Previously, these assumed that <code>errno</code> contained
      information describing the failure.  Now,
      an <code>apr_status_t</code> parameter must be provided.  Pass
      0/APR_SUCCESS if there is no such error information, or a valid

      values set in it are no longer visible to modules.  (Most can
      still be overridden at build time.)  <code>DEFAULT_PIDLOG</code>
      and <code>DEFAULT_REL_RUNTIMEDIR</code> are now universally
      available via <code>ap_config.h</code>.</dd>

      <dt><code>unixd_config</code></dt>
      <dd>This has been renamed to ap_unixd_config.</dd>

      <dt><code>unixd_setup_child()</code></dt>

          should call the added ap_run_drop_privileges() hook.</dd>

      <dt><code>conn_rec-&gt;remote_ip</code> and
          <code>conn_rec-&gt;remote_addr</code></dt>
      <dd>These fields have been renamed in order to distinguish between
      the client IP address of the connection and the useragent IP address
      of the request (potentially overridden by a load balancer or proxy).
      References to either of these fields must be updated with one of the
      following options, as appropriate for the module:
      <ul>
        <li>When you require the IP address of the user agent, which
        might be connected directly to the server, or might optionally be
        separated from the server by a transparent load balancer or
        proxy, use <code>request_rec-&gt;useragent_ip</code> and
        <code>request_rec-&gt;useragent_addr</code>.</li>
        <li>When you require the IP address of the client that is
        connected directly to the server, which might be the useragent or
        might be the load balancer or proxy itself, use
        <code>conn_rec-&gt;client_ip</code> and
        <code>conn_rec-&gt;client_addr</code>.</li>
      </ul>
      </dd>

          also log the value of the new
          field <code>suexec_disabled_reason</code>, which contains an
          explanation of why it is not available.</dd>

      <dt>Extended status data in the scoreboard</dt>
      <dd>In previous releases, <code>ExtendedStatus</code> had to be
          set to <code>On</code>, which in turn required that
          mod_status was loaded.  In 2.4, just
          set <code>ap_extended_status</code> to <code>1</code> in a
          pre-config hook and the extended status data will be

    <p>Apache 2.0 使用 <a href="http://www.doxygen.org/">Doxygen</a> 从代码中
    生成 API 和全局变量的文档。下面是对使用 Doxygen 生成文档的简介。</p>
</div>
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="brief" id="brief">简要说明</a></h2>
    <p>使用 <code>/**</code> 开始文档块<br />
    使用 <code>*/</code> 结束文档块</p>

    <p>在文档块中，我们可以使用多个标签:</p>

    <div class="example"><p><code>
      Description of this functions purpose<br />
      @param parameter_name description<br />
      @return description<br />
      @deffunc signature of the function<br />
    </code></p></div>
      
    <p>一般不需要 <code>deffunc</code> 。DoxyGen 没有完整的解析器，所以任何
    在返回类型声明中使用宏的原型，都是太复杂了。这些函数就需要使用 <code>deffunc</code>。
    例如 (使用 &amp;gt; 而不是 &gt;):</p>

    <div class="example"><p><code>
      /**<br />
 &nbsp;* return the final element of the pathname<br />
 &nbsp;* @param pathname The path to get the final element of<br />
 &nbsp;* @return the final element of the path<br />
 &nbsp;* @tip Examples:<br />
 &nbsp;* &lt;pre&gt;<br />
 &nbsp;*                 "/foo/bar/gum"   -&amp;gt; "gum"<br />
 &nbsp;*                 "/foo/bar/gum/"  -&amp;gt; ""<br />
 &nbsp;*                 "gum"            -&amp;gt; "gum"<br />
 &nbsp;*                 "wi\\n32\\stuff" -&amp;gt; "stuff"<br />
 &nbsp;* &lt;/pre&gt;<br />
 &nbsp;* @deffunc const char * ap_filename_of_pathname(const char *pathname)<br />
 &nbsp;*/
    </code></p></div>

    <p>总是在头文件开始包含:</p>
    <div class="example"><p><code>
      /**<br />
 &nbsp;* @package Name of library header<br />
 &nbsp;*/
    </code></p></div>

    <p>Doxygen 为每个包生成一个新的 HTML 文件，名字是
    {Name_of_library_header}.html，所以请简化名称。</p>

    <p>更深入的讨论，请参见
    <a href="http://www.doxygen.org/">Doxygen 站点</a>。</p>

    <div class="warning"><h3>Warning</h3>
      <p>Warning - this is a first (fast) draft that needs further
      revision!</p>
    </div>

    <p>Several changes in 2.0 and above affect the internal request
    processing mechanics. Module authors need to be aware of these
    changes so they may take advantage of the optimizations and
    security enhancements.</p>

    <p>The first major change is to the subrequest and redirect
    mechanisms. There were a number of different code paths in
    the Apache HTTP Server 1.3 to attempt to optimize subrequest 
    or redirect behavior. As patches were introduced to 2.0, these
    optimizations (and the server behavior) were quickly broken due
    to this duplication of code. All duplicate code has been folded
    back into <code>ap_process_request_internal()</code> to prevent
    the code from falling out of sync again.</p>

    <p>This means that much of the existing code was 'unoptimized'.
    It is the Apache HTTP Project's first goal to create a robust
    and correct implementation of the HTTP server RFC. Additional
    goals include security, scalability and optimization. New
    methods were sought to optimize the server (beyond the
    performance of 1.3) without introducing fragile or
    insecure code.</p>

<h2><a name="processing" id="processing">The Request Processing Cycle</a></h2>
    <p>All requests pass through <code>ap_process_request_internal()</code>
    in <code>server/request.c</code>, including subrequests and redirects. If a module
    doesn't pass generated requests through this code, the author is cautioned
    that the module may be broken by future changes to request
    processing.</p>

    <p>To streamline requests, the module author can take advantage
    of the <a href="./modguide.html#hooking">hooks offered</a> to drop 
    out of the request cycle early, or to bypass core hooks which are 
    irrelevant (and costly in terms of CPU.)</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="parsing" id="parsing">The Request Parsing Phase</a></h2>
    <h3><a name="unescape" id="unescape">Unescapes the URL</a></h3>
      <p>The request's <code>parsed_uri</code> path is unescaped, once and only
      once, at the beginning of internal request processing.</p>

      <p>This step is bypassed if the proxyreq flag is set, or the
      <code>parsed_uri.path</code> element is unset. The module has no further
      control of this one-time unescape operation, either failing to
      unescape or multiply unescaping the URL leads to security
      repercussions.</p>
    

    <h3><a name="strip" id="strip">Strips Parent and This Elements from the
    URI</a></h3>
      <p>All <code>/../</code> and <code>/./</code> elements are
      removed by <code>ap_getparents()</code>, as well as any trailing 
      <code>/.</code> or <code>/..</code> element. This helps to ensure
      the path is (nearly) absolute before the request processing
      continues. (See RFC 1808 section 4 for further discussion.)</p>

      <p>This step cannot be bypassed.</p>
    

    <h3><a name="inital-location-walk" id="inital-location-walk">Initial URI Location Walk</a></h3>
      <p>Every request is subject to an
      <code>ap_location_walk()</code> call. This ensures that
      <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code> sections
      are consistently enforced for all requests. If the request is an internal
      redirect or a sub-request, it may borrow some or all of the processing
      from the previous or parent request's ap_location_walk, so this step
      is generally very efficient after processing the main request.</p>
    

    <h3><a name="translate_name" id="translate_name">translate_name</a></h3>
      <p>Modules can determine the file name, or alter the given URI
      in this step. For example, <code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code> will
      translate the URI's path into the configured virtual host,
      <code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> will translate the path to an alias path,
      and if the request falls back on the core, the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> is prepended to the request resource.</p>

      <p>If all modules <code>DECLINE</code> this phase, an error 500 is
      returned to the browser, and a "couldn't translate name" error is logged
      automatically.</p>
    

    <h3><a name="map_to_storage" id="map_to_storage">Hook: map_to_storage</a></h3>
      <p>After the file or correct URI was determined, the
      appropriate per-dir configurations are merged together. For
      example, <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> compares and merges the appropriate
      <code class="directive"><a href="../mod/mod_proxy.html#proxy">&lt;Proxy&gt;</a></code> sections.
      If the URI is nothing more than a local (non-proxy) <code>TRACE</code>
      request, the core handles the request and returns <code>DONE</code>.
      If no module answers this hook with <code>OK</code> or <code>DONE</code>,
      the core will run the request filename against the <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> and <code class="directive"><a href="../mod/core.html#files">&lt;Files&gt;</a></code> sections. If the request
      'filename' isn't an absolute, legal filename, a note is set for
      later termination.</p>
    

    <h3><a name="location-walk" id="location-walk">URI Location Walk</a></h3>
      <p>Every request is hardened by a second
      <code>ap_location_walk()</code> call. This reassures that a
      translated request is still subjected to the configured
      <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code> sections.
      The request again borrows some or all of the processing from its previous
      <code>location_walk</code> above, so this step is almost always very
      efficient unless the translated URI mapped to a substantially different
      path or Virtual Host.</p>
    

    <h3><a name="header_parser" id="header_parser">Hook: header_parser</a></h3>
      <p>The main request then parses the client's headers. This
      prepares the remaining request processing steps to better serve
      the client's request.</p>

<h2><a name="preparation" id="preparation">The Preparation Phase</a></h2>
    <h3><a name="type_checker" id="type_checker">Hook: type_checker</a></h3>
      <p>The modules have an opportunity to test the URI or filename
      against the target resource, and set mime information for the
      request. Both <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> and
      <code class="module"><a href="../mod/mod_mime_magic.html">mod_mime_magic</a></code> use this phase to compare the file
      name or contents against the administrator's configuration and set the
      content type, language, character set and request handler. Some modules
      may set up their filters or other request handling parameters at this
      time.</p>

      <p>If all modules <code>DECLINE</code> this phase, an error 500 is
      returned to the browser, and a "couldn't find types" error is logged
      automatically.</p>
    

    <h3><a name="fixups" id="fixups">Hook: fixups</a></h3>
      <p>Many modules are 'trounced' by some phase above. The fixups
      phase is used by modules to 'reassert' their ownership or force
      the request's fields to their appropriate values. It isn't
      always the cleanest mechanism, but occasionally it's the only
      option.</p>
    
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="handler" id="handler">The Handler Phase</a></h2>
    <p>This phase is <strong>not</strong> part of the processing in
    <code>ap_process_request_internal()</code>. Many
    modules prepare one or more subrequests prior to creating any
    content at all. After the core, or a module calls
    <code>ap_process_request_internal()</code> it then calls
    <code>ap_invoke_handler()</code> to generate the request.</p>

    <h3><a name="insert_filter" id="insert_filter">Hook: insert_filter</a></h3>
      <p>Modules that transform the content in some way can insert
      their values and override existing filters, such that if the
      user configured a more advanced filter out-of-order, then the
      module can move its order as need be.  There is no result code,
      so actions in this hook better be trusted to always succeed.</p>
    

    <h3><a name="hook_handler" id="hook_handler">Hook: handler</a></h3>
      <p>The module finally has a chance to serve the request in its
      handler hook. Note that not every prepared request is sent to
      the handler hook. Many modules, such as <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code>,
      will create subrequests for a given URI, and then never serve the
      subrequest, but simply lists it for the user. Remember not to
      put required teardown from the hooks above into this module,
      but register pool cleanups against the request pool to free
      resources as required.</p>

<h2><a name="easy" id="easy">The easier changes ...</a></h2>

    <h3><a name="cleanup" id="cleanup">Cleanup Routines</a></h3>
      <p>These now need to be of type <code>apr_status_t</code> and return a
      value of that type. Normally the return value will be
      <code>APR_SUCCESS</code> unless there is some need to signal an error in
      the cleanup. Be aware that even though you signal an error not all code
      yet checks and acts upon the error.</p>
    

    <h3><a name="init" id="init">Initialisation Routines</a></h3>
      <p>These should now be renamed to better signify where they sit
      in the overall process. So the name gets a small change from
      <code>mmap_init</code> to <code>mmap_post_config</code>. The arguments
      passed have undergone a radical change and now look like</p>

      <ul>

<h2><a name="messy" id="messy">The messier changes...</a></h2>

    <h3><a name="register-hooks" id="register-hooks">Register Hooks</a></h3>
      <p>The new architecture uses a series of hooks to provide for
      calling your functions. These you'll need to add to your module
      by way of a new function, <code>static void register_hooks(void)</code>.
      The function is really reasonably straightforward once you
      understand what needs to be done. Each function that needs
      calling at some stage in the processing of a request needs to
      be registered, handlers do not. There are a number of phases
      where functions can be added, and for each you can specify with
      a high degree of control the relative order that the function
      will be called in.</p>

      <p>This is the code that was added to <code>mod_mmap_static</code>:</p>
      <div class="example"><pre>static void register_hooks(void)
{
    static const char * const aszPre[]={ "http_core.c",NULL };
    ap_hook_post_config(mmap_post_config,NULL,NULL,HOOK_MIDDLE);
    ap_hook_translate_name(mmap_static_xlat,aszPre,NULL,HOOK_LAST);
};</pre></div>

      <p>This registers 2 functions that need to be called, one in
      the <code>post_config</code> stage (virtually every module will need this
      one) and one for the <code>translate_name</code> phase. note that while
      there are different function names the format of each is
      identical. So what is the format?</p>

      <div class="example"><p><code>
        ap_hook_<var>phase_name</var>(<var>function_name</var>,
        <var>predecessors</var>, <var>successors</var>, <var>position</var>);
      </code></p></div>

      <p>There are 3 hook positions defined...</p>

      <ul>
        <li><code>HOOK_FIRST</code></li>
        <li><code>HOOK_MIDDLE</code></li>
        <li><code>HOOK_LAST</code></li>
      </ul>

      <p>To define the position you use the position and then modify
      it with the predecessors and successors. Each of the modifiers
      can be a list of functions that should be called, either before
      the function is run (predecessors) or after the function has
      run (successors).</p>

      <p>In the <code>mod_mmap_static</code> case I didn't care about the
      <code>post_config</code> stage, but the <code>mmap_static_xlat</code>
      <strong>must</strong> be called after the core module had done its name
      translation, hence the use of the aszPre to define a modifier to the
      position <code>HOOK_LAST</code>.</p>
    

    <h3><a name="moddef" id="moddef">Module Definition</a></h3>
      <p>There are now a lot fewer stages to worry about when
      creating your module definition. The old definition looked
      like</p>

      <div class="example"><pre>module MODULE_VAR_EXPORT <var>module_name</var>_module =
{
    STANDARD_MODULE_STUFF,
    /* initializer */
    /* dir config creater */
    /* dir merger --- default is to override */
    /* server config */
    /* merge server config */
    /* command handlers */
    /* handlers */
    /* filename translation */
    /* check_user_id */
    /* check auth */
    /* check access */
    /* type_checker */
    /* fixups */
    /* logger */
    /* header parser */
    /* child_init */
    /* child_exit */
    /* post read-request */
};</pre></div>

      <p>The new structure is a great deal simpler...</p>
      <div class="example"><pre>module MODULE_VAR_EXPORT <var>module_name</var>_module =
{
    STANDARD20_MODULE_STUFF,
    /* create per-directory config structures */
    /* merge per-directory config structures  */
    /* create per-server config structures    */
    /* merge per-server config structures     */
    /* command handlers */
    /* handlers */
    /* register hooks */
};</pre></div>

      <p>Some of these read directly across, some don't. I'll try to
      summarise what should be done below.</p>

      <p>The stages that read directly across :</p>

      <dl>
        <dt><code>/* dir config creater */</code></dt>
        <dd><code>/* create per-directory config structures */</code></dd>

        <dt><code>/* server config */</code></dt>
        <dd><code>/* create per-server config structures */</code></dd>

        <dt><code>/* dir merger */</code></dt>
        <dd><code>/* merge per-directory config structures */</code></dd>

        <dt><code>/* merge server config */</code></dt>
        <dd><code>/* merge per-server config structures */</code></dd>

        <dt><code>/* command table */</code></dt>
        <dd><code>/* command apr_table_t */</code></dd>

        <dt><code>/* handlers */</code></dt>
        <dd><code>/* handlers */</code></dd>
      </dl>

      <p>The remainder of the old functions should be registered as
      hooks. There are the following hook stages defined so
      far...</p>

      <dl>
        <dt><code>ap_hook_pre_config</code></dt>
        <dd>do any setup required prior to processing configuration

<a href="http://www.apache.org/">Apache</a> &gt; <a href="http://httpd.apache.org/">HTTP Server</a> &gt; <a href="http://httpd.apache.org/docs/">Documentation</a> &gt; <a href="../">Version 2.4</a> &gt; <a href="./">Developer Documentation</a></div><div id="page-content"><div id="preamble"><h1>Documenting code in Apache 2.4</h1>
<div class="toplang">
<p><span>Available Languages: </span><a href="../en/developer/documenting.html" title="English">&nbsp;en&nbsp;</a> |

</div>

    <p>Apache 2.4 uses <a href="http://www.doxygen.org/">Doxygen</a> to
    document the APIs and global variables in the code. This will explain
    the basics of how to document using Doxygen.</p>
</div>
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="brief" id="brief">Brief Description</a></h2>
    <p>To start a documentation block, use <code>/**</code><br />
    To end a documentation block, use <code>*/</code></p>

    <p>In the middle of the block, there are multiple tags we can
    use:</p>

    <div class="example"><p><code>
      Description of this functions purpose<br />
      @param parameter_name description<br />
      @return description<br />
      @deffunc signature of the function<br />
    </code></p></div>

    <p>The <code>deffunc</code> is not always necessary. DoxyGen does not
    have a full parser  in it, so any prototype that use a macro in the
    return type declaration is too complex for scandoc. Those functions
    require a <code>deffunc</code>. An example (using &amp;gt; rather
    than &gt;):</p>

    <div class="example"><p><code>
      /**<br />
 &nbsp;* return the final element of the pathname<br />
 &nbsp;* @param pathname The path to get the final element of<br />
 &nbsp;* @return the final element of the path<br />
 &nbsp;* @tip Examples:<br />
 &nbsp;* &lt;pre&gt;<br />
 &nbsp;*                 "/foo/bar/gum"   -&amp;gt; "gum"<br />
 &nbsp;*                 "/foo/bar/gum/"  -&amp;gt; ""<br />
 &nbsp;*                 "gum"            -&amp;gt; "gum"<br />
 &nbsp;*                 "wi\\n32\\stuff" -&amp;gt; "stuff"<br />
 &nbsp;* &lt;/pre&gt;<br />
 &nbsp;* @deffunc const char * ap_filename_of_pathname(const char *pathname)<br />
 &nbsp;*/
    </code></p></div>

    <p>At the top of the header file, always include:</p>
    <div class="example"><p><code>
      /**<br />
 &nbsp;* @package Name of library header<br />
 &nbsp;*/
    </code></p></div>

    <p>Doxygen uses a new HTML file for each package. The HTML files are named
    {Name_of_library_header}.html, so try to be concise with your names.</p>

    <p>For a further discussion of the possibilities please refer to
    <a href="http://www.doxygen.org/">the Doxygen site</a>.</p>

    <p>In general, a hook function is one that the Apache HTTP Server
    will call at some point during the processing of a request.
    Modules can provide functions that are called, and specify when
    they get called in comparison to other modules.</p>

<h2><a name="corehooks" id="corehooks">Core Hooks</a></h2>
    <p>The httpd's core modules offer a predefinined list of hooks
    used during the standard <a href="./request.html">request processing</a>
    phase. Creating a new hook will expose a function that 
    implements it (see sections below) but it is essential to understand that you will not 
    extend the httpd's core hooks. Their presence and order in the request processing is in fact 
    a consequence of how they are called in <code>server/request.c</code> 
    (check <a href="./modguide.html#hooking">this section</a> 
    for an overview). The core hooks are listed in the 
    <a href="https://ci.apache.org/projects/httpd/trunk/doxygen/group__hooks.html">doxygen documentation</a>.</p>

    <p>Reading <a href="./modguide.html">guide for developing modules</a> and 
    <a href="./request.html">request processing</a> before proceeding is 
    highly recommended.
    </p> 
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="create" id="create">Creating a hook function</a></h2>
    <p>In order to create a new hook, four things need to be
    done:</p>

    <h3><a name="create-declare" id="create-declare">Declare the hook function</a></h3>
      <p>Use the <code>AP_DECLARE_HOOK</code> macro, which needs to be given
      the return type of the hook function, the name of the hook, and the
      arguments. For example, if the hook returns an <code>int</code> and
      takes a <code>request_rec *</code> and an <code>int</code> and is
      called <code>do_something</code>, then declare it like this:</p>
      <pre class="prettyprint lang-c">AP_DECLARE_HOOK(int, do_something, (request_rec *r, int n))</pre>


      <p>This should go in a header which modules will include if
      they want to use the hook.</p>
    

    <h3><a name="create-create" id="create-create">Create the hook structure</a></h3>
      <p>Each source file that exports a hook has a private structure
      which is used to record the module functions that use the hook.
      This is declared as follows:</p>

      <pre class="prettyprint lang-c">APR_HOOK_STRUCT(
  APR_HOOK_LINK(do_something)
  ...
)</pre>

    

    <h3><a name="create-implement" id="create-implement">Implement the hook caller</a></h3>
      <p>The source file that exports the hook has to implement a
      function that will call the hook. There are currently three
      possible ways to do this. In all cases, the calling function is
      called <code>ap_run_<var>hookname</var>()</code>.</p>

      <h4>Void hooks</h4>
        <p>If the return value of a hook is <code>void</code>, then all the
        hooks are called, and the caller is implemented like this:</p>

        <pre class="prettyprint lang-c">AP_IMPLEMENT_HOOK_VOID(do_something, (request_rec *r, int n), (r, n))</pre>


        <p>The second and third arguments are the dummy argument
        declaration and the dummy arguments as they will be used when
        calling the hook. In other words, this macro expands to
        something like this:</p>

        <pre class="prettyprint lang-c">void ap_run_do_something(request_rec *r, int n)
{
    ...
    do_something(r, n);
}</pre>

      

      <h4>Hooks that return a value</h4>
        <p>If the hook returns a value, then it can either be run until
        the first hook that does something interesting, like so:</p>

        <pre class="prettyprint lang-c">AP_IMPLEMENT_HOOK_RUN_FIRST(int, do_something, (request_rec *r, int n), (r, n), DECLINED)</pre>


        <p>The first hook that does <em>not</em> return <code>DECLINED</code>
        stops the loop and its return value is returned from the hook
        caller. Note that <code>DECLINED</code> is the traditional
        hook return value meaning "I didn't do anything", but it can be
        whatever suits you.</p>

        <p>Alternatively, all hooks can be run until an error occurs.
        This boils down to permitting <em>two</em> return values, one of
        which means "I did something, and it was OK" and the other
        meaning "I did nothing". The first function that returns a
        value other than one of those two stops the loop, and its
        return is the return value. Declare these like so:</p>

        <pre class="prettyprint lang-c">AP_IMPLEMENT_HOOK_RUN_ALL(int, do_something, (request_rec *r, int n), (r, n), OK, DECLINED)</pre>


        <p>Again, <code>OK</code> and <code>DECLINED</code> are the traditional
        values. You can use what you want.</p>
      
    

    <h3><a name="create-call" id="create-call">Call the hook callers</a></h3>
      <p>At appropriate moments in the code, call the hook caller,
      like so:</p>

      <pre class="prettyprint lang-c">int n, ret;
request_rec *r;

ret=ap_run_do_something(r, n);</pre>

    
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="hooking" id="hooking">Hooking the hook</a></h2>
    <p>A module that wants a hook to be called needs to do two
    things.</p>

    <h3><a name="hooking-implement" id="hooking-implement">Implement the hook function</a></h3>
      <p>Include the appropriate header, and define a static function
      of the correct type:</p>

      <pre class="prettyprint lang-c">static int my_something_doer(request_rec *r, int n)
{
    ...
    return OK;
}</pre>

    

    <h3><a name="hooking-add" id="hooking-add">Add a hook registering function</a></h3>
      <p>During initialisation, the server will call each modules hook
      registering function, which is included in the module
      structure:</p>

      <pre class="prettyprint lang-c">static void my_register_hooks()
{
    ap_hook_do_something(my_something_doer, NULL, NULL, APR_HOOK_MIDDLE);
}

mode MODULE_VAR_EXPORT my_module =
{
    ...
    my_register_hooks       /* register hooks */
};</pre>

    

    <h3><a name="hooking-order" id="hooking-order">Controlling hook calling order</a></h3>
      <p>In the example above, we didn't use the three arguments in
      the hook registration function that control calling order of 
      all the functions registered within the hook.
      There are two mechanisms for doing this. The first, rather
      crude, method, allows us to specify roughly where the hook is
      run relative to other modules. The final argument control this.
      There are three possible values: <code>APR_HOOK_FIRST</code>,
      <code>APR_HOOK_MIDDLE</code> and <code>APR_HOOK_LAST</code>.</p>

      <p>All modules using any particular value may be run in any
      order relative to each other, but, of course, all modules using
      <code>APR_HOOK_FIRST</code> will be run before <code>APR_HOOK_MIDDLE</code>
      which are before <code>APR_HOOK_LAST</code>. Modules that don't care
      when they are run should use <code>APR_HOOK_MIDDLE</code>. <em>These
      values are spaced out, so that positions like <code>APR_HOOK_FIRST-2</code>
      are possible to hook slightly earlier than other functions.</em></p>

      <p>Note that there are two more values,
      <code>APR_HOOK_REALLY_FIRST</code> and <code>APR_HOOK_REALLY_LAST</code>. These
      should only be used by the hook exporter.</p>

      <p>The other method allows finer control. When a module knows
      that it must be run before (or after) some other modules, it
      can specify them by name. The second (third) argument is a
      NULL-terminated array of strings consisting of the names of
      modules that must be run before (after) the current module. For
      example, suppose we want "mod_xyz.c" and "mod_abc.c" to run
      before we do, then we'd hook as follows:</p>

      <pre class="prettyprint lang-c">static void register_hooks()
{
    static const char * const aszPre[] = { "mod_xyz.c", "mod_abc.c", NULL };

    ap_hook_do_something(my_something_doer, aszPre, NULL, APR_HOOK_MIDDLE);
}</pre>


      <p>Note that the sort used to achieve this is stable, so
      ordering set by <code>APR_HOOK_<var>ORDER</var></code> is preserved, as far
      as is possible.</p>

    <div class="warning"><h3>Warning</h3>
      <p>This document has not been updated to take into account changes made
      in the 2.0 version of the Apache HTTP Server. Some of the information may
      still be relevant, but please use it with care.</p>
    </div>

    <p>These are some notes on the Apache API and the data structures you have
    to deal with, <em>etc.</em> They are not yet nearly complete, but hopefully,
    they will help you get your bearings. Keep in mind that the API is still
    subject to change as we gain experience with it. (See the TODO file for
    what <em>might</em> be coming). However, it will be easy to adapt modules
    to any changes that are made. (We have more modules to adapt than you
    do).</p>

    <p>A few notes on general pedagogical style here. In the interest of
    conciseness, all structure declarations here are incomplete -- the real
    ones have more slots that I'm not telling you about. For the most part,
    these are reserved to one component of the server core or another, and
    should be altered by modules with caution. However, in some cases, they
    really are things I just haven't gotten around to yet. Welcome to the
    bleeding edge.</p>

    <p>Finally, here's an outline, to give you some bare idea of what's coming
    up, and in what order:</p>

<div class="section">
<h2><a name="basics" id="basics">Basic concepts</a></h2>
    <p>We begin with an overview of the basic concepts behind the API, and how
    they are manifested in the code.</p>

    <h3><a name="HMR" id="HMR">Handlers, Modules, and Requests</a></h3>
      <p>Apache breaks down request handling into a series of steps, more or
      less the same way the Netscape server API does (although this API has a
      few more stages than NetSite does, as hooks for stuff I thought might be
      useful in the future). These are:</p>

      <ul>
      <li>URI -&gt; Filename translation</li>
      <li>Auth ID checking [is the user who they say they are?]</li>
      <li>Auth access checking [is the user authorized <em>here</em>?]</li>
      <li>Access checking other than auth</li>
      <li>Determining MIME type of the object requested</li>
      <li>`Fixups' -- there aren't any of these yet, but the phase is intended
      as a hook for possible extensions like <code class="directive"><a href="../mod/mod_env.html#setenv">SetEnv</a></code>, which don't really fit well elsewhere.</li>
      <li>Actually sending a response back to the client.</li>
      <li>Logging the request</li>
      </ul>

      <p>These phases are handled by looking at each of a succession of
      <em>modules</em>, looking to see if each of them has a handler for the
      phase, and attempting invoking it if so. The handler can typically do one
      of three things:</p>

      <ul>
      <li><em>Handle</em> the request, and indicate that it has done so by
      returning the magic constant <code>OK</code>.</li>

      <li><em>Decline</em> to handle the request, by returning the magic integer
      constant <code>DECLINED</code>. In this case, the server behaves in all
      respects as if the handler simply hadn't been there.</li>

      <li>Signal an error, by returning one of the HTTP error codes. This
      terminates normal handling of the request, although an ErrorDocument may
      be invoked to try to mop up, and it will be logged in any case.</li>
      </ul>

      <p>Most phases are terminated by the first module that handles them;
      however, for logging, `fixups', and non-access authentication checking,
      all handlers always run (barring an error). Also, the response phase is
      unique in that modules may declare multiple handlers for it, via a
      dispatch table keyed on the MIME type of the requested object. Modules may
      declare a response-phase handler which can handle <em>any</em> request,
      by giving it the key <code>*/*</code> (<em>i.e.</em>, a wildcard MIME type
      specification). However, wildcard handlers are only invoked if the server
      has already tried and failed to find a more specific response handler for
      the MIME type of the requested object (either none existed, or they all
      declined).</p>

      <p>The handlers themselves are functions of one argument (a
      <code>request_rec</code> structure. vide infra), which returns an integer,
      as above.</p>
    

    <h3><a name="moduletour" id="moduletour">A brief tour of a module</a></h3>
      <p>At this point, we need to explain the structure of a module. Our
      candidate will be one of the messier ones, the CGI module -- this handles
      both CGI scripts and the <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code> config file command. It's actually a great deal
      more complicated than most modules, but if we're going to have only one
      example, it might as well be the one with its fingers in every place.</p>

      <p>Let's begin with handlers. In order to handle the CGI scripts, the
      module declares a response handler for them. Because of <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>, it also has handlers for the
      name translation phase (to recognize <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>ed URIs), the type-checking phase (any
      <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>ed request is typed
      as a CGI script).</p>

      <p>The module needs to maintain some per (virtual) server information,
      namely, the <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>es in
      effect; the module structure therefore contains pointers to a functions
      which builds these structures, and to another which combines two of them
      (in case the main server and a virtual server both have <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>es declared).</p>

      <p>Finally, this module contains code to handle the <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code> command itself. This particular
      module only declares one command, but there could be more, so modules have
      <em>command tables</em> which declare their commands, and describe where
      they are permitted, and how they are to be invoked.</p>

      <p>A final note on the declared types of the arguments of some of these
      commands: a <code>pool</code> is a pointer to a <em>resource pool</em>
      structure; these are used by the server to keep track of the memory which
      has been allocated, files opened, <em>etc.</em>, either to service a
      particular request, or to handle the process of configuring itself. That
      way, when the request is over (or, for the configuration pool, when the
      server is restarting), the memory can be freed, and the files closed,
      <em>en masse</em>, without anyone having to write explicit code to track
      them all down and dispose of them. Also, a <code>cmd_parms</code>
      structure contains various information about the config file being read,

<div class="section">
<h2><a name="handlers" id="handlers">How handlers work</a></h2>
    <p>The sole argument to handlers is a <code>request_rec</code> structure.
    This structure describes a particular request which has been made to the
    server, on behalf of a client. In most cases, each connection to the
    client generates only one <code>request_rec</code> structure.</p>

    <h3><a name="req_tour" id="req_tour">A brief tour of the request_rec</a></h3>
      <p>The <code>request_rec</code> contains pointers to a resource pool
      which will be cleared when the server is finished handling the request;
      to structures containing per-server and per-connection information, and
      most importantly, information on the request itself.</p>

      <p>The most important such information is a small set of character strings
      describing attributes of the object being requested, including its URI,
      filename, content-type and content-encoding (these being filled in by the
      translation and type-check handlers which handle the request,
      respectively).</p>

      <p>Other commonly used data items are tables giving the MIME headers on
      the client's original request, MIME headers to be sent back with the
      response (which modules can add to at will), and environment variables for
      any subprocesses which are spawned off in the course of servicing the
      request. These tables are manipulated using the <code>ap_table_get</code>
      and <code>ap_table_set</code> routines.</p>

      <div class="note">
        <p>Note that the <code>Content-type</code> header value <em>cannot</em>
        be set by module content-handlers using the <code>ap_table_*()</code>
        routines. Rather, it is set by pointing the <code>content_type</code>
        field in the <code>request_rec</code> structure to an appropriate
        string. <em>e.g.</em>,</p>
        <div class="example"><p><code>
          r-&gt;content_type = "text/html";
        </code></p></div>
      </div>

      <p>Finally, there are pointers to two data structures which, in turn,
      point to per-module configuration structures. Specifically, these hold
      pointers to the data structures which the module has built to describe
      the way it has been configured to operate in a given directory (via
      <code>.htaccess</code> files or <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections), for private data it has built in the
      course of servicing the request (so modules' handlers for one phase can
      pass `notes' to their handlers for other phases). There is another such
      configuration vector in the <code>server_rec</code> data structure pointed
      to by the <code>request_rec</code>, which contains per (virtual) server
      configuration data.</p>

      <p>Here is an abridged declaration, giving the fields most commonly
      used:</p>

    <h3><a name="req_orig" id="req_orig">Where request_rec structures come from</a></h3>
      <p>Most <code>request_rec</code> structures are built by reading an HTTP
      request from a client, and filling in the fields. However, there are a
      few exceptions:</p>

      <ul>
      <li>If the request is to an imagemap, a type map (<em>i.e.</em>, a
      <code>*.var</code> file), or a CGI script which returned a local
      `Location:', then the resource which the user requested is going to be
      ultimately located by some URI other than what the client originally
      supplied. In this case, the server does an <em>internal redirect</em>,
      constructing a new <code>request_rec</code> for the new URI, and
      processing it almost exactly as if the client had requested the new URI
      directly.</li>

      <li>If some handler signaled an error, and an <code>ErrorDocument</code>
      is in scope, the same internal redirect machinery comes into play.</li>

      <li><p>Finally, a handler occasionally needs to investigate `what would
      happen if' some other request were run. For instance, the directory
      indexing module needs to know what MIME type would be assigned to a
      request for each directory entry, in order to figure out what icon to
      use.</p>

      <p>Such handlers can construct a <em>sub-request</em>, using the
      functions <code>ap_sub_req_lookup_file</code>,
      <code>ap_sub_req_lookup_uri</code>, and <code>ap_sub_req_method_uri</code>;
      these construct a new <code>request_rec</code> structure and processes it
      as you would expect, up to but not including the point of actually sending
      a response. (These functions skip over the access checks if the
      sub-request is for a file in the same directory as the original
      request).</p>

      <p>(Server-side includes work by building sub-requests and then actually
      invoking the response handler for them, via the function
      <code>ap_run_sub_req</code>).</p>
      </li>
      </ul>
    

    <h3><a name="req_return" id="req_return">Handling requests, declining, and returning
    error codes</a></h3>
      <p>As discussed above, each handler, when invoked to handle a particular
      <code>request_rec</code>, has to return an <code>int</code> to indicate
      what happened. That can either be</p>

      <ul>
      <li><code>OK</code> -- the request was handled successfully. This may or
      may not terminate the phase.</li>

      <li><code>DECLINED</code> -- no erroneous condition exists, but the module
      declines to handle the phase; the server tries to find another.</li>

      <li>an HTTP error code, which aborts handling of the request.</li>
      </ul>

      <p>Note that if the error code returned is <code>REDIRECT</code>, then
      the module should put a <code>Location</code> in the request's
      <code>headers_out</code>, to indicate where the client should be
      redirected <em>to</em>.</p>
    

    <h3><a name="resp_handlers" id="resp_handlers">Special considerations for response
    handlers</a></h3>
      <p>Handlers for most phases do their work by simply setting a few fields
      in the <code>request_rec</code> structure (or, in the case of access
      checkers, simply by returning the correct error code). However, response
      handlers have to actually send a request back to the client.</p>

      <p>They should begin by sending an HTTP response header, using the
      function <code>ap_send_http_header</code>. (You don't have to do anything
      special to skip sending the header for HTTP/0.9 requests; the function
      figures out on its own that it shouldn't do anything). If the request is
      marked <code>header_only</code>, that's all they should do; they should
      return after that, without attempting any further output.</p>

      <p>Otherwise, they should produce a request body which responds to the
      client as appropriate. The primitives for this are <code>ap_rputc</code>
      and <code>ap_rprintf</code>, for internally generated output, and
      <code>ap_send_fd</code>, to copy the contents of some <code>FILE *</code>
      straight to the client.</p>

      <p>At this point, you should more or less understand the following piece
      of code, which is the handler which handles <code>GET</code> requests
      which have no more specific handler; it also shows how conditional
      <code>GET</code>s can be handled, if it's desirable to do so in a
      particular response handler -- <code>ap_set_last_modified</code> checks
      against the <code>If-modified-since</code> value supplied by the client,
      if any, and returns an appropriate code (which will, if nonzero, be
      USE_LOCAL_COPY). No similar considerations apply for
      <code>ap_set_content_length</code>, but it returns an error code for
      symmetry.</p>

      <div class="example"><p><code>
        int default_handler (request_rec *r)<br />
        {<br />
        <span class="indent">
          int errstatus;<br />
          FILE *f;<br />
          <br />
          if (r-&gt;method_number != M_GET) return DECLINED;<br />
          if (r-&gt;finfo.st_mode == 0) return NOT_FOUND;<br />
          <br />
          if ((errstatus = ap_set_content_length (r, r-&gt;finfo.st_size))<br />
          &nbsp;&nbsp;&nbsp;&nbsp;||
             (errstatus = ap_set_last_modified (r, r-&gt;finfo.st_mtime)))<br />
          return errstatus;<br />
          <br />
          f = fopen (r-&gt;filename, "r");<br />
          <br />
          if (f == NULL) {<br />
          <span class="indent">
            log_reason("file permissions deny server access", r-&gt;filename, r);<br />
            return FORBIDDEN;<br />
          </span>
          }<br />
          <br />
          register_timeout ("send", r);<br />
          ap_send_http_header (r);<br />
          <br />
          if (!r-&gt;header_only) send_fd (f, r);<br />
          ap_pfclose (r-&gt;pool, f);<br />
          return OK;<br />
        </span>
        }
      </code></p></div>

      <p>Finally, if all of this is too much of a challenge, there are a few
      ways out of it. First off, as shown above, a response handler which has
      not yet produced any output can simply return an error code, in which
      case the server will automatically produce an error response. Secondly,
      it can punt to some other handler by invoking
      <code>ap_internal_redirect</code>, which is how the internal redirection
      machinery discussed above is invoked. A response handler which has
      internally redirected should always return <code>OK</code>.</p>

      <p>(Invoking <code>ap_internal_redirect</code> from handlers which are
      <em>not</em> response handlers will lead to serious confusion).</p>
    

    <h3><a name="auth_handlers" id="auth_handlers">Special considerations for authentication
    handlers</a></h3>
      <p>Stuff that should be discussed here in detail:</p>

      <ul>
      <li>Authentication-phase handlers not invoked unless auth is
      configured for the directory.</li>

      <li>Common auth configuration stored in the core per-dir
      configuration; it has accessors <code>ap_auth_type</code>,
      <code>ap_auth_name</code>, and <code>ap_requires</code>.</li>

      <li>Common routines, to handle the protocol end of things, at
      least for HTTP basic authentication
      (<code>ap_get_basic_auth_pw</code>, which sets the
      <code>connection-&gt;user</code> structure field
      automatically, and <code>ap_note_basic_auth_failure</code>,
      which arranges for the proper <code>WWW-Authenticate:</code>
      header to be sent back).</li>
      </ul>
    

    <h3><a name="log_handlers" id="log_handlers">Special considerations for logging
    handlers</a></h3>
      <p>When a request has internally redirected, there is the question of
      what to log. Apache handles this by bundling the entire chain of redirects
      into a list of <code>request_rec</code> structures which are threaded
      through the <code>r-&gt;prev</code> and <code>r-&gt;next</code> pointers.
      The <code>request_rec</code> which is passed to the logging handlers in
      such cases is the one which was originally built for the initial request
      from the client; note that the <code>bytes_sent</code> field will only be
      correct in the last request in the chain (the one for which a response was
      actually sent).</p>
    
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="pools" id="pools">Resource allocation and resource pools</a></h2>
    <p>One of the problems of writing and designing a server-pool server is
    that of preventing leakage, that is, allocating resources (memory, open
    files, <em>etc.</em>), without subsequently releasing them. The resource
    pool machinery is designed to make it easy to prevent this from happening,
    by allowing resource to be allocated in such a way that they are
    <em>automatically</em> released when the server is done with them.</p>

    <p>The way this works is as follows: the memory which is allocated, file
    opened, <em>etc.</em>, to deal with a particular request are tied to a
    <em>resource pool</em> which is allocated for the request. The pool is a
    data structure which itself tracks the resources in question.</p>

    <p>When the request has been processed, the pool is <em>cleared</em>. At
    that point, all the memory associated with it is released for reuse, all
    files associated with it are closed, and any other clean-up functions which
    are associated with the pool are run. When this is over, we can be confident
    that all the resource tied to the pool have been released, and that none of
    them have leaked.</p>

    <p>Server restarts, and allocation of memory and resources for per-server
    configuration, are handled in a similar way. There is a <em>configuration
    pool</em>, which keeps track of resources which were allocated while reading
    the server configuration files, and handling the commands therein (for
    instance, the memory that was allocated for per-server module configuration,
    log files and other files that were opened, and so forth). When the server
    restarts, and has to reread the configuration files, the configuration pool
    is cleared, and so the memory and file descriptors which were taken up by
    reading them the last time are made available for reuse.</p>

    <p>It should be noted that use of the pool machinery isn't generally
    obligatory, except for situations like logging handlers, where you really
    need to register cleanups to make sure that the log file gets closed when
    the server restarts (this is most easily done by using the function <code><a href="#pool-files">ap_pfopen</a></code>, which also arranges for the
    underlying file descriptor to be closed before any child processes, such as
    for CGI scripts, are <code>exec</code>ed), or in case you are using the
    timeout machinery (which isn't yet even documented here). However, there are
    two benefits to using it: resources allocated to a pool never leak (even if
    you allocate a scratch string, and just forget about it); also, for memory
    allocation, <code>ap_palloc</code> is generally faster than
    <code>malloc</code>.</p>

    <p>We begin here by describing how memory is allocated to pools, and then
    discuss how other resources are tracked by the resource pool machinery.</p>

    <h3>Allocation of memory in pools</h3>
      <p>Memory is allocated to pools by calling the function
      <code>ap_palloc</code>, which takes two arguments, one being a pointer to
      a resource pool structure, and the other being the amount of memory to
      allocate (in <code>char</code>s). Within handlers for handling requests,
      the most common way of getting a resource pool structure is by looking at
      the <code>pool</code> slot of the relevant <code>request_rec</code>; hence
      the repeated appearance of the following idiom in module code:</p>

      <div class="example"><p><code>
        int my_handler(request_rec *r)<br />
        {<br />
        <span class="indent">
          struct my_structure *foo;<br />
          ...<br />
          <br />
          foo = (foo *)ap_palloc (r-&gt;pool, sizeof(my_structure));<br />
        </span>
        }
      </code></p></div>

      <p>Note that <em>there is no <code>ap_pfree</code></em> --
      <code>ap_palloc</code>ed memory is freed only when the associated resource
      pool is cleared. This means that <code>ap_palloc</code> does not have to
      do as much accounting as <code>malloc()</code>; all it does in the typical
      case is to round up the size, bump a pointer, and do a range check.</p>

      <p>(It also raises the possibility that heavy use of
      <code>ap_palloc</code> could cause a server process to grow excessively
      large. There are two ways to deal with this, which are dealt with below;
      briefly, you can use <code>malloc</code>, and try to be sure that all of
      the memory gets explicitly <code>free</code>d, or you can allocate a
      sub-pool of the main pool, allocate your memory in the sub-pool, and clear
      it out periodically. The latter technique is discussed in the section
      on sub-pools below, and is used in the directory-indexing code, in order
      to avoid excessive storage allocation when listing directories with
      thousands of files).</p>
    

    <h3>Allocating initialized memory</h3>
      <p>There are functions which allocate initialized memory, and are
      frequently useful. The function <code>ap_pcalloc</code> has the same
      interface as <code>ap_palloc</code>, but clears out the memory it
      allocates before it returns it. The function <code>ap_pstrdup</code>
      takes a resource pool and a <code>char *</code> as arguments, and
      allocates memory for a copy of the string the pointer points to, returning
      a pointer to the copy. Finally <code>ap_pstrcat</code> is a varargs-style
      function, which takes a pointer to a resource pool, and at least two
      <code>char *</code> arguments, the last of which must be
      <code>NULL</code>. It allocates enough memory to fit copies of each of
      the strings, as a unit; for instance:</p>

      <div class="example"><p><code>
        ap_pstrcat (r-&gt;pool, "foo", "/", "bar", NULL);
      </code></p></div>

      <p>returns a pointer to 8 bytes worth of memory, initialized to
      <code>"foo/bar"</code>.</p>
    

    <h3><a name="pools-used" id="pools-used">Commonly-used pools in the Apache Web
    server</a></h3>
      <p>A pool is really defined by its lifetime more than anything else.
      There are some static pools in http_main which are passed to various
      non-http_main functions as arguments at opportune times. Here they
      are:</p>

      <dl>
      <dt><code>permanent_pool</code></dt>

          until the server is terminated or restarts; passed to all
          config-time routines, either via cmd-&gt;pool, or as the
          "pool *p" argument on those which don't take pools</li>

          referring to the use of ptrans in the parent... contrast
          this with the later definition of ptrans in the

          "bastard child" because it isn't available everywhere.
          Used for temporary scratch space which may be needed by
          some config routines but which is deleted at the end of

          the first thing palloc()d from it</li>
        </ul>
      </dd>
      </dl>

      <p>For almost everything folks do, <code>r-&gt;pool</code> is the pool to
      use. But you can see how other lifetimes, such as pchild, are useful to
      some modules... such as modules that need to open a database connection
      once per child, and wish to clean it up when the child dies.</p>

      <p>You can also see how some bugs have manifested themself, such as
      setting <code>connection-&gt;user</code> to a value from
      <code>r-&gt;pool</code> -- in this case connection exists for the
      lifetime of <code>ptrans</code>, which is longer than
      <code>r-&gt;pool</code> (especially if <code>r-&gt;pool</code> is a
      subrequest!). So the correct thing to do is to allocate from
      <code>connection-&gt;pool</code>.</p>

      <p>And there was another interesting bug in <code class="module"><a href="../mod/mod_include.html">mod_include</a></code>
      / <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code>. You'll see in those that they do this test
      to decide if they should use <code>r-&gt;pool</code> or
      <code>r-&gt;main-&gt;pool</code>. In this case the resource that they are
      registering for cleanup is a child process. If it were registered in
      <code>r-&gt;pool</code>, then the code would <code>wait()</code> for the
      child when the subrequest finishes. With <code class="module"><a href="../mod/mod_include.html">mod_include</a></code> this
      could be any old <code>#include</code>, and the delay can be up to 3
      seconds... and happened quite frequently. Instead the subprocess is
      registered in <code>r-&gt;main-&gt;pool</code> which causes it to be
      cleaned up when the entire request is done -- <em>i.e.</em>, after the
      output has been sent to the client and logging has happened.</p>
    

    <h3><a name="pool-files" id="pool-files">Tracking open files, etc.</a></h3>
      <p>As indicated above, resource pools are also used to track other sorts
      of resources besides memory. The most common are open files. The routine
      which is typically used for this is <code>ap_pfopen</code>, which takes a
      resource pool and two strings as arguments; the strings are the same as
      the typical arguments to <code>fopen</code>, <em>e.g.</em>,</p>

      <div class="example"><p><code>
        ...<br />
        FILE *f = ap_pfopen (r-&gt;pool, r-&gt;filename, "r");<br />
        <br />
        if (f == NULL) { ... } else { ... }<br />
      </code></p></div>

      <p>There is also a <code>ap_popenf</code> routine, which parallels the
      lower-level <code>open</code> system call. Both of these routines arrange
      for the file to be closed when the resource pool in question is
      cleared.</p>

      <p>Unlike the case for memory, there <em>are</em> functions to close files
      allocated with <code>ap_pfopen</code>, and <code>ap_popenf</code>, namely
      <code>ap_pfclose</code> and <code>ap_pclosef</code>. (This is because, on
      many systems, the number of files which a single process can have open is
      quite limited). It is important to use these functions to close files
      allocated with <code>ap_pfopen</code> and <code>ap_popenf</code>, since to
      do otherwise could cause fatal errors on systems such as Linux, which
      react badly if the same <code>FILE*</code> is closed more than once.</p>

      <p>(Using the <code>close</code> functions is not mandatory, since the
      file will eventually be closed regardless, but you should consider it in
      cases where your module is opening, or could open, a lot of files).</p>
    

    <h3>Other sorts of resources -- cleanup functions</h3>
      <p>More text goes here. Describe the cleanup primitives in terms of
      which the file stuff is implemented; also, <code>spawn_process</code>.</p>

      <p>Pool cleanups live until <code>clear_pool()</code> is called:
      <code>clear_pool(a)</code> recursively calls <code>destroy_pool()</code>
      on all subpools of <code>a</code>; then calls all the cleanups for
      <code>a</code>; then releases all the memory for <code>a</code>.
      <code>destroy_pool(a)</code> calls <code>clear_pool(a)</code> and then
      releases the pool structure itself. <em>i.e.</em>,
      <code>clear_pool(a)</code> doesn't delete <code>a</code>, it just frees
      up all the resources and you can start using it again immediately.</p>
    

    <h3>Fine control -- creating and dealing with sub-pools, with
    a note on sub-requests</h3>
      <p>On rare occasions, too-free use of <code>ap_palloc()</code> and the
      associated primitives may result in undesirably profligate resource
      allocation. You can deal with such a case by creating a <em>sub-pool</em>,
      allocating within the sub-pool rather than the main pool, and clearing or
      destroying the sub-pool, which releases the resources which were
      associated with it. (This really <em>is</em> a rare situation; the only
      case in which it comes up in the standard module set is in case of listing
      directories, and then only with <em>very</em> large directories.
      Unnecessary use of the primitives discussed here can hair up your code
      quite a bit, with very little gain).</p>

      <p>The primitive for creating a sub-pool is <code>ap_make_sub_pool</code>,
      which takes another pool (the parent pool) as an argument. When the main
      pool is cleared, the sub-pool will be destroyed. The sub-pool may also be
      cleared or destroyed at any time, by calling the functions
      <code>ap_clear_pool</code> and <code>ap_destroy_pool</code>, respectively.
      (The difference is that <code>ap_clear_pool</code> frees resources
      associated with the pool, while <code>ap_destroy_pool</code> also
      deallocates the pool itself. In the former case, you can allocate new
      resources within the pool, and clear it again, and so forth; in the
      latter case, it is simply gone).</p>

      <p>One final note -- sub-requests have their own resource pools, which are
      sub-pools of the resource pool for the main request. The polite way to
      reclaim the resources associated with a sub request which you have
      allocated (using the <code>ap_sub_req_...</code> functions) is
      <code>ap_destroy_sub_req</code>, which frees the resource pool. Before
      calling this function, be sure to copy anything that you care about which
      might be allocated in the sub-request's resource pool into someplace a
      little less volatile (for instance, the filename in its
      <code>request_rec</code> structure).</p>

      <p>(Again, under most circumstances, you shouldn't feel obliged to call
      this function; only 2K of memory or so are allocated for a typical sub
      request, and it will be freed anyway when the main request pool is
      cleared. It is only when you are allocating many, many sub-requests for a
      single main request that you should seriously consider the
      <code>ap_destroy_...</code> functions).</p>

<div class="section">
<h2><a name="config" id="config">Configuration, commands and the like</a></h2>
    <p>One of the design goals for this server was to maintain external
    compatibility with the NCSA 1.3 server --- that is, to read the same
    configuration files, to process all the directives therein correctly, and
    in general to be a drop-in replacement for NCSA. On the other hand, another
    design goal was to move as much of the server's functionality into modules
    which have as little as possible to do with the monolithic server core. The
    only way to reconcile these goals is to move the handling of most commands
    from the central server into the modules.</p>

    <p>However, just giving the modules command tables is not enough to divorce
    them completely from the server core. The server has to remember the
    commands in order to act on them later. That involves maintaining data which
    is private to the modules, and which can be either per-server, or
    per-directory. Most things are per-directory, including in particular access
    control and authorization information, but also information on how to
    determine file types from suffixes, which can be modified by
    <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code> and <code class="directive"><a href="../mod/core.html#forcetype">ForceType</a></code> directives, and so forth. In general,
    the governing philosophy is that anything which <em>can</em> be made
    configurable by directory should be; per-server information is generally
    used in the standard set of modules for information like
    <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>es and <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code>s which come into play before the
    request is tied to a particular place in the underlying file system.</p>

    <p>Another requirement for emulating the NCSA server is being able to handle
    the per-directory configuration files, generally called
    <code>.htaccess</code> files, though even in the NCSA server they can
    contain directives which have nothing at all to do with access control.
    Accordingly, after URI -&gt; filename translation, but before performing any
    other phase, the server walks down the directory hierarchy of the underlying
    filesystem, following the translated pathname, to read any
    <code>.htaccess</code> files which might be present. The information which
    is read in then has to be <em>merged</em> with the applicable information
    from the server's own config files (either from the <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections in
    <code>access.conf</code>, or from defaults in <code>srm.conf</code>, which
    actually behaves for most purposes almost exactly like <code>&lt;Directory
    /&gt;</code>).</p>

    <p>Finally, after having served a request which involved reading
    <code>.htaccess</code> files, we need to discard the storage allocated for
    handling them. That is solved the same way it is solved wherever else
    similar problems come up, by tying those structures to the per-transaction
    resource pool.</p>

    <h3><a name="per-dir" id="per-dir">Per-directory configuration structures</a></h3>
      <p>Let's look out how all of this plays out in <code>mod_mime.c</code>,
      which defines the file typing handler which emulates the NCSA server's
      behavior of determining file types from suffixes. What we'll be looking
      at, here, is the code which implements the <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code> and <code class="directive"><a href="../mod/mod_mime.html#addencoding">AddEncoding</a></code> commands. These commands can appear in
      <code>.htaccess</code> files, so they must be handled in the module's
      private per-directory data, which in fact, consists of two separate
      tables for MIME types and encoding information, and is declared as
      follows:</p>

      <div class="example"><pre>typedef struct {
    table *forced_types;      /* Additional AddTyped stuff */
    table *encoding_types;    /* Added with AddEncoding... */
} mime_dir_config;</pre></div>

      <p>When the server is reading a configuration file, or <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> section, which includes
      one of the MIME module's commands, it needs to create a
      <code>mime_dir_config</code> structure, so those commands have something
      to act on. It does this by invoking the function it finds in the module's
      `create per-dir config slot', with two arguments: the name of the
      directory to which this configuration information applies (or
      <code>NULL</code> for <code>srm.conf</code>), and a pointer to a
      resource pool in which the allocation should happen.</p>

      <p>(If we are reading a <code>.htaccess</code> file, that resource pool
      is the per-request resource pool for the request; otherwise it is a
      resource pool which is used for configuration data, and cleared on
      restarts. Either way, it is important for the structure being created to
      vanish when the pool is cleared, by registering a cleanup on the pool if
      necessary).</p>

      <p>For the MIME module, the per-dir config creation function just
      <code>ap_palloc</code>s the structure above, and a creates a couple of
      tables to fill it. That looks like this:</p>

      <div class="example"><p><code>
        void *create_mime_dir_config (pool *p, char *dummy)<br />
        {<br />
        <span class="indent">
          mime_dir_config *new =<br />
          <span class="indent">
           (mime_dir_config *) ap_palloc (p, sizeof(mime_dir_config));<br />
          </span>
          <br />
          new-&gt;forced_types = ap_make_table (p, 4);<br />
          new-&gt;encoding_types = ap_make_table (p, 4);<br />
          <br />
          return new;<br />
        </span>
        }
      </code></p></div>

      <p>Now, suppose we've just read in a <code>.htaccess</code> file. We
      already have the per-directory configuration structure for the next
      directory up in the hierarchy. If the <code>.htaccess</code> file we just
      read in didn't have any <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code>
      or <code class="directive"><a href="../mod/mod_mime.html#addencoding">AddEncoding</a></code> commands, its
      per-directory config structure for the MIME module is still valid, and we
      can just use it. Otherwise, we need to merge the two structures
      somehow.</p>

      <p>To do that, the server invokes the module's per-directory config merge
      function, if one is present. That function takes three arguments: the two
      structures being merged, and a resource pool in which to allocate the
      result. For the MIME module, all that needs to be done is overlay the
      tables from the new per-directory config structure with those from the
      parent:</p>

      <div class="example"><p><code>
        void *merge_mime_dir_configs (pool *p, void *parent_dirv, void *subdirv)<br />
        {<br />
        <span class="indent">
          mime_dir_config *parent_dir = (mime_dir_config *)parent_dirv;<br />
          mime_dir_config *subdir = (mime_dir_config *)subdirv;<br />
          mime_dir_config *new =<br />
          <span class="indent">
            (mime_dir_config *)ap_palloc (p, sizeof(mime_dir_config));<br />
          </span>
          <br />
          new-&gt;forced_types = ap_overlay_tables (p, subdir-&gt;forced_types,<br />
          <span class="indent">
            parent_dir-&gt;forced_types);<br />
          </span>
          new-&gt;encoding_types = ap_overlay_tables (p, subdir-&gt;encoding_types,<br />
          <span class="indent">
            parent_dir-&gt;encoding_types);<br />
          </span>
          <br />
          return new;<br />
        </span>
        }
      </code></p></div>

      <p>As a note -- if there is no per-directory merge function present, the
      server will just use the subdirectory's configuration info, and ignore
      the parent's. For some modules, that works just fine (<em>e.g.</em>, for
      the includes module, whose per-directory configuration information
      consists solely of the state of the <code>XBITHACK</code>), and for those
      modules, you can just not declare one, and leave the corresponding
      structure slot in the module itself <code>NULL</code>.</p>
    

    <h3><a name="commands" id="commands">Command handling</a></h3>
      <p>Now that we have these structures, we need to be able to figure out how
      to fill them. That involves processing the actual <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code> and <code class="directive"><a href="../mod/mod_mime.html#addencoding">AddEncoding</a></code> commands. To find commands, the server looks in
      the module's command table. That table contains information on how many
      arguments the commands take, and in what formats, where it is permitted,
      and so forth. That information is sufficient to allow the server to invoke
      most command-handling functions with pre-parsed arguments. Without further
      ado, let's look at the <code class="directive"><a href="../mod/mod_mime.html#addtype">AddType</a></code>
      command handler, which looks like this (the <code class="directive"><a href="../mod/mod_mime.html#addencoding">AddEncoding</a></code> command looks basically the same, and won't be
      shown here):</p>

      <div class="example"><p><code>
        char *add_type(cmd_parms *cmd, mime_dir_config *m, char *ct, char *ext)<br />
        {<br />
        <span class="indent">
          if (*ext == '.') ++ext;<br />
          ap_table_set (m-&gt;forced_types, ext, ct);<br />
          return NULL;<br />
        </span>
        }
      </code></p></div>

      <p>This command handler is unusually simple. As you can see, it takes
      four arguments, two of which are pre-parsed arguments, the third being the
      per-directory configuration structure for the module in question, and the
      fourth being a pointer to a <code>cmd_parms</code> structure. That
      structure contains a bunch of arguments which are frequently of use to
      some, but not all, commands, including a resource pool (from which memory
      can be allocated, and to which cleanups should be tied), and the (virtual)
      server being configured, from which the module's per-server configuration
      data can be obtained if required.</p>

      <p>Another way in which this particular command handler is unusually
      simple is that there are no error conditions which it can encounter. If
      there were, it could return an error message instead of <code>NULL</code>;
      this causes an error to be printed out on the server's
      <code>stderr</code>, followed by a quick exit, if it is in the main config
      files; for a <code>.htaccess</code> file, the syntax error is logged in
      the server error log (along with an indication of where it came from), and
      the request is bounced with a server error response (HTTP error status,
      code 500).</p>

      <p>The MIME module's command table has entries for these commands, which
      look like this:</p>

      <div class="example"><p><code>
        command_rec mime_cmds[] = {<br />
        <span class="indent">
          { "AddType", add_type, NULL, OR_FILEINFO, TAKE2,<br />
          <span class="indent">"a mime type followed by a file extension" },<br /></span>
          { "AddEncoding", add_encoding, NULL, OR_FILEINFO, TAKE2,<br />
          <span class="indent">
          "an encoding (<em>e.g.</em>, gzip), followed by a file extension" },<br />
          </span>
          { NULL }<br />
        </span>
        };
      </code></p></div>

      <p>The entries in these tables are:</p>
      <ul>
      <li>The name of the command</li>
      <li>The function which handles it</li>
      <li>a <code>(void *)</code> pointer, which is passed in the
      <code>cmd_parms</code> structure to the command handler ---
      this is useful in case many similar commands are handled by
      the same function.</li>

      <li>A bit mask indicating where the command may appear. There
      are mask bits corresponding to each
      <code>AllowOverride</code> option, and an additional mask
      bit, <code>RSRC_CONF</code>, indicating that the command may
      appear in the server's own config files, but <em>not</em> in
      any <code>.htaccess</code> file.</li>

      <li>A flag indicating how many arguments the command handler
      wants pre-parsed, and how they should be passed in.
      <code>TAKE2</code> indicates two pre-parsed arguments. Other
      options are <code>TAKE1</code>, which indicates one
      pre-parsed argument, <code>FLAG</code>, which indicates that
      the argument should be <code>On</code> or <code>Off</code>,
      and is passed in as a boolean flag, <code>RAW_ARGS</code>,
      which causes the server to give the command the raw, unparsed
      arguments (everything but the command name itself). There is
      also <code>ITERATE</code>, which means that the handler looks
      the same as <code>TAKE1</code>, but that if multiple
      arguments are present, it should be called multiple times,
      and finally <code>ITERATE2</code>, which indicates that the
      command handler looks like a <code>TAKE2</code>, but if more
      arguments are present, then it should be called multiple
      times, holding the first argument constant.</li>

      <li>Finally, we have a string which describes the arguments
      that should be present. If the arguments in the actual config
      file are not as required, this string will be used to help
      give a more specific error message. (You can safely leave
      this <code>NULL</code>).</li>
      </ul>

      <p>Finally, having set this all up, we have to use it. This is ultimately
      done in the module's handlers, specifically for its file-typing handler,
      which looks more or less like this; note that the per-directory
      configuration structure is extracted from the <code>request_rec</code>'s
      per-directory configuration vector by using the
      <code>ap_get_module_config</code> function.</p>

    <h3><a name="servconf" id="servconf">Side notes -- per-server configuration,
    virtual servers, <em>etc</em>.</a></h3>
      <p>The basic ideas behind per-server module configuration are basically
      the same as those for per-directory configuration; there is a creation
      function and a merge function, the latter being invoked where a virtual
      server has partially overridden the base server configuration, and a
      combined structure must be computed. (As with per-directory configuration,
      the default if no merge function is specified, and a module is configured
      in some virtual server, is that the base configuration is simply
      ignored).</p>

      <p>The only substantial difference is that when a command needs to
      configure the per-server private module data, it needs to go to the
      <code>cmd_parms</code> data to get at it. Here's an example, from the
      alias module, which also indicates how a syntax error can be returned
      (note that the per-directory configuration argument to the command
      handler is declared as a dummy, since the module doesn't actually have
      per-directory config data):</p>

      <div class="example"><p><code>
        char *add_redirect(cmd_parms *cmd, void *dummy, char *f, char *url)<br />
        {<br />
        <span class="indent">
          server_rec *s = cmd-&gt;server;<br />
          alias_server_conf *conf = (alias_server_conf *)<br />
          <span class="indent">
            ap_get_module_config(s-&gt;module_config,&amp;alias_module);<br />
          </span>
          alias_entry *new = ap_push_array (conf-&gt;redirects);<br />
          <br />
          if (!ap_is_url (url)) return "Redirect to non-URL";<br />
          <br />
          new-&gt;fake = f; new-&gt;real = url;<br />
          return NULL;<br />
        </span>

<h2><a name="introduction" id="introduction">Introduction</a></h2>
<h3><a name="what" id="what">What we will be discussing in this document</a></h3>
<p>
This document will discuss how you can create modules for the Apache 
HTTP Server 2.4, by exploring an example module called 
<code>mod_example</code>. In the first part of this document, the purpose 
of this module will be to calculate and print out various digest values for 
existing files on your web server, whenever we access the URL <code>
http://hostname/filename.sum</code>. For instance, if we want to know the 
MD5 digest value of the file located at <code>
http://www.example.com/index.html</code>, we would visit <code>
http://www.example.com/index.html.sum</code>. 
</p>

<p>
In the second part of this document, which deals with configuration 
directive and context awareness, we will be looking at a module that simply 
writes out its own configuration to the client.
</p>


<h3><a name="prerequisites" id="prerequisites">Prerequisites</a></h3>
<p>
First and foremost, you are expected to have a basic knowledge of how the C 
programming language works. In most cases, we will try to be as pedagogical 
as possible and link to documents describing the functions used in the 
examples, but there are also many cases where it is necessary to either 
just assume that "it works" or do some digging yourself into what the hows 
and whys of various function calls. 
</p>
<p>
Lastly, you will need to have a basic understanding of how modules are 
loaded and configured in the Apache HTTP Server, as well as how to get the headers for 
Apache if you do not have them already, as these are needed for compiling 
new modules.
</p>

<h3><a name="compiling" id="compiling">Compiling your module</a></h3>
<p>
To compile the source code we are building in this document, we will be 
using <a href="../programs/apxs.html">APXS</a>. Assuming your source file 
is called mod_example.c, compiling, installing and activating the module is 
as simple as: 
</p>
<div class="example"><pre>apxs -i -a -c mod_example.c</pre></div>


</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="basics" id="basics">Defining a module</a></h2>
<p>
<img src="../images/build_a_mod_3.png" alt="Module name tags" /><br />
Every module starts with the same declaration, or name tag if you will, 
that defines a module as <em>a separate entity within Apache</em>:</p>



<pre class="prettyprint lang-c">module AP_MODULE_DECLARE_DATA   example_module =
{ 
    STANDARD20_MODULE_STUFF,
    create_dir_conf, /* Per-directory configuration handler */
    merge_dir_conf,  /* Merge handler for per-directory configurations */
    create_svr_conf, /* Per-server configuration handler */
    merge_svr_conf,  /* Merge handler for per-server configurations */
    directives,      /* Any directives we may have for httpd */
    register_hooks   /* Our hook registering function */
};</pre>



<p>
This bit of code lets the server know that we have now registered a new module 
in the system, and that its name is <code>example_module</code>. The name 
of the module is used primarily for two things:<br />
</p>
<ul>
<li>Letting the server know how to load the module using the LoadModule</li>
<li>Setting up a namespace for the module to use in configurations</li>
</ul>
<p>
For now, we're only concerned with the first purpose of the module name, 
which comes into play when we need to load the module:
</p>
<pre class="prettyprint lang-config">LoadModule example_module modules/mod_example.so</pre>

<p>
In essence, this tells the server to open up <code>mod_example.so</code> and look for a module 
called <code>example_module</code>.
</p>
<p>
Within this name tag of ours is also a bunch of references to how we would 
like to handle things: Which directives do we respond to in a configuration 
file or .htaccess, how do we operate within specific contexts, and what 
handlers are we interested in registering with the Apache HTTP service. We'll 
return to all these elements later in this document.

<h2><a name="hooking" id="hooking">Getting started: Hooking into the server</a></h2>
<h3><a name="hook_intro" id="hook_intro">An introduction to hooks</a></h3>
<p>
When handling requests in Apache HTTP Server 2.4, the first thing you will need to do is 
create a hook into the request handling process. A hook is essentially a 
message telling the server that you are willing to either serve or at least 
take a glance at certain requests given by clients. All handlers, whether 
it's mod_rewrite, mod_authn_*, mod_proxy and so on, are hooked into 
specific parts of the request process. As you are probably aware, modules 
serve different purposes; Some are authentication/authorization handlers, 
others are file or script handlers while some third modules rewrite URIs or 
proxies content. Furthermore, in the end, it is up to the user of the server 
how and when each module will come into place. Thus, the server itself does not 
presume to know which module is responsible for handling a specific 
request, and will ask each module whether they have an interest in a given 
request or not. It is then up to each module to either gently decline 
serving a request, accept serving it or flat out deny the request from 
being served, as authentication/authorization modules do: <br />
<img src="../images/build_a_mod_2.png" alt="Hook handling in httpd" /><br />
To make it a bit easier for handlers such as our mod_example to know 
whether the client is requesting content we should handle or not, the server 
has directives for hinting to modules whether their assistance is needed or 
not. Two of these are <code class="directive"><a href="../mod/mod_mime.html#addhandler">AddHandler</a></code> 
and <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>. Let's take a look at 
an example using <code class="directive"><a href="../mod/mod_mime.html#addhandler">AddHandler</a></code>. In 
our example case, we want every request ending with .sum to be served by 
<code>mod_example</code>, so we'll add a configuration directive that tells 
the server to do just that:
</p>
<pre class="prettyprint lang-config">AddHandler example-handler .sum</pre>

<p>
What this tells the server is the following: <em>Whenever we receive a request 
for a URI ending in .sum, we are to let all modules know that we are 
looking for whoever goes by the name of "example-handler" </em>. 
Thus, when a request is being served that ends in .sum, the server will let all 
modules know, that this request should be served by "example-handler
". As you will see later, when we start building mod_example, we will 
check for this handler tag relayed by <code>AddHandler</code> and reply to 
the server based on the value of this tag.
</p>

<h3><a name="hook_declaration" id="hook_declaration">Hooking into httpd</a></h3>
<p>
To begin with, we only want to create a simple handler that replies to the 
client browser when a specific URL is requested, so we won't bother setting 
up configuration handlers and directives just yet. Our initial module 
definition will look like this:</p>



<pre class="prettyprint lang-c">module AP_MODULE_DECLARE_DATA   example_module =
{
    STANDARD20_MODULE_STUFF,
    NULL,
    NULL,
    NULL,
    NULL,
    NULL,
    register_hooks   /* Our hook registering function */
};</pre>




<p>This lets the server know that we are not interested in anything fancy, we 
just want to hook onto the requests and possibly handle some of them. </p> 

<p> The reference in our example declaration, <code>register_hooks</code> 
is the name of a function we will create to manage how we hook onto the 
request process. In this example module, the function has just one purpose; 
To create a simple hook that gets called after all the rewrites, access 
control etc has been handled. Thus, we will let the server know that we want 
to hook into its process as one of the last modules: 
</p>


<pre class="prettyprint lang-c">static void register_hooks(apr_pool_t *pool)
{
    /* Create a hook in the request handler, so we get called when a request arrives */
    ap_hook_handler(example_handler, NULL, NULL, APR_HOOK_LAST);
}</pre>



<p>
The <code>example_handler</code> reference is the function that will handle 
the request. We will discuss how to create a handler in the next chapter.
</p>

<h3><a name="hook_others" id="hook_others">Other useful hooks</a></h3>
<p>
Hooking into the request handling phase is but one of many hooks that you 
can create. Some other ways of hooking are:
</p>
<ul>
<li><code>ap_hook_child_init</code>: Place a hook that executes when a child process is spawned (commonly used for initializing modules after the server has forked)</li>
<li><code>ap_hook_pre_config</code>: Place a hook that executes before any configuration data has been read (very early hook)</li>
<li><code>ap_hook_post_config</code>: Place a hook that executes after configuration has been parsed, but before the server has forked</li>
<li><code>ap_hook_pre_translate_name</code>: Place a hook that executes when a URI needs to be translated into a filename on the server, before decoding</li>
<li><code>ap_hook_translate_name</code>: Place a hook that executes when a URI needs to be translated into a filename on the server (think <code>mod_rewrite</code>)</li>
<li><code>ap_hook_quick_handler</code>: Similar to <code>ap_hook_handler</code>, except it is run before any other request hooks (translation, auth, fixups etc)</li>
<li><code>ap_hook_log_transaction</code>: Place a hook that executes when the server is about to add a log entry of the current request</li>
</ul>


</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="handling" id="handling">Building a handler</a></h2>
<p>
A handler is essentially a function that receives a callback when a request 
to the server is made. It is passed a record of the current request (how it was 
made, which headers and requests were passed along, who's giving the 
request and so on), and is put in charge of either telling the server that it's 
not interested in the request or handle the request with the tools provided.
</p>
<h3><a name="simple_handler" id="simple_handler">A simple "Hello, world!" 
handler</a></h3> 
<p>Let's start off by making a very simple request handler 
that does the following:
</p>
<ol>
<li>Check that this is a request that should be served by "example-handler"</li>
<li>Set the content type of our output to <code>text/html</code></li>
<li>Write "Hello, world!" back to the client browser</li>
<li>Let the server know that we took care of this request and everything went fine</li>
</ol>
<p>
In C code, our example handler will now look like this:
</p>


<pre class="prettyprint lang-c">static int example_handler(request_rec *r)
{
    /* First off, we need to check if this is a call for the "example-handler" handler.
     * If it is, we accept it and do our things, if not, we simply return DECLINED,
     * and the server will try somewhere else.
     */
    if (!r-&gt;handler || strcmp(r-&gt;handler, "example-handler")) return (DECLINED);
    
    /* Now that we are handling this request, we'll write out "Hello, world!" to the client.
     * To do so, we must first set the appropriate content type, followed by our output.
     */
    ap_set_content_type(r, "text/html");
    ap_rprintf(r, "Hello, world!");
    
    /* Lastly, we must tell the server that we took care of this request and everything went fine.
     * We do so by simply returning the value OK to the server.
     */
    return OK;
}</pre>



<p>
Now, we put all we have learned together and end up with a program that 
looks like 
<a href="http://people.apache.org/~humbedooh/mods/examples/mod_example_1.c">mod_example_1.c</a>
. The functions used in this example will be explained later in the section 
<a href="#functions">"Some useful functions you should know"</a>. 
</p>
 
<h3><a name="request_rec" id="request_rec">The request_rec structure</a></h3> 
<p>The most essential part of any request is the <em>request record
</em>. In a call to a handler function, this is represented by the <code>
request_rec* </code> structure passed along with every call that is made. 
This struct, typically just referred to as <code>r</code> in modules, 
contains all the information you need for your module to fully process any 
HTTP request and respond accordingly.</p> <p>Some key elements of the <code>
request_rec </code> structure are:
</p>
<ul>
<li><code>r-&gt;handler (char*):</code> Contains the name of the handler the server is currently asking to do the handling of this request</li>
<li><code>r-&gt;method (char*):</code> Contains the HTTP method being used, f.x. GET or POST</li>
<li><code>r-&gt;filename (char*):</code> Contains the translated filename the client is requesting</li>
<li><code>r-&gt;args (char*):</code> Contains the query string of the request, if any</li>
<li><code>r-&gt;headers_in (apr_table_t*):</code> Contains all the headers sent by the client</li>
<li><code>r-&gt;connection (conn_rec*):</code> A record containing information about the current connection</li>
<li><code>r-&gt;user (char*):</code> If the URI requires authentication, this is set to the username provided</li>
<li><code>r-&gt;useragent_ip (char*):</code> The IP address of the client connecting to us</li>
<li><code>r-&gt;pool (apr_pool_t*)</code>: The memory pool of this request. We'll discuss this in the 
"<a href="#memory">Memory management</a>" chapter.</li>
</ul>
<p>
A complete list of all the values contained within the <code>request_rec</code> structure can be found in 
the <a href="http://svn.apache.org/repos/asf/httpd/httpd/trunk/include/httpd.h"><code>httpd.h</code></a> header 
file or at <a href="http://ci.apache.org/projects/httpd/trunk/doxygen/structrequest__rec.html">http://ci.apache.org/projects/httpd/trunk/doxygen/structrequest__rec.html</a>.
</p>


<p>
Let's try out some of these variables in another example handler:<br />
</p>


<pre class="prettyprint lang-c">static int example_handler(request_rec *r)
{
    /* Set the appropriate content type */
    ap_set_content_type(r, "text/html");

    /* Print out the IP address of the client connecting to us: */
    ap_rprintf(r, "&lt;h2&gt;Hello, %s!&lt;/h2&gt;", r-&gt;useragent_ip);
    
    /* If we were reached through a GET or a POST request, be happy, else sad. */
    if ( !strcmp(r-&gt;method, "POST") || !strcmp(r-&gt;method, "GET") ) {
        ap_rputs("You used a GET or a POST method, that makes us happy!&lt;br/&gt;", r);
    }
    else {
        ap_rputs("You did not use POST or GET, that makes us sad :(&lt;br/&gt;", r);
    }

    /* Lastly, if there was a query string, let's print that too! */
    if (r-&gt;args) {
        ap_rprintf(r, "Your query string was: %s", r-&gt;args);
    }
    return OK;
}</pre>





<h3><a name="return_value" id="return_value">Return values</a></h3>
<p>
Apache relies on return values from handlers to signify whether a request 
was handled or not, and if so, whether the request went well or not. If a 
module is not interested in handling a specific request, it should always 
return the value <code>DECLINED</code>. If it is handling a request, it 
should either return the generic value <code>OK</code>, or a specific HTTP 
status code, for example:
</p>


<pre class="prettyprint lang-c">static int example_handler(request_rec *r)
{
    /* Return 404: Not found */
    return HTTP_NOT_FOUND;
}</pre>



<p>
Returning <code>OK</code> or a HTTP status code does not necessarily mean 
that the request will end. The server may still have other handlers that are 
interested in this request, for instance the logging modules which, upon a 
successful request, will write down a summary of what was requested and how 
it went. To do a full stop and prevent any further processing after your 
module is done, you can return the value <code>DONE</code> to let the server 
know that it should cease all activity on this request and carry on with 
the next, without informing other handlers.
<br />
<strong>General response codes:</strong>
</p>
<ul>
<li><code>DECLINED</code>: We are not handling this request</li>
<li><code>OK</code>: We handled this request and it went well</li>
<li><code>DONE</code>: We handled this request and the server should just close this thread without further processing</li>
</ul>
<p>
<strong>HTTP specific return codes (excerpt):</strong>
</p>
<ul>
<li><code>HTTP_OK (200)</code>: Request was okay</li>
<li><code>HTTP_MOVED_PERMANENTLY (301)</code>: The resource has moved to a new URL</li>
<li><code>HTTP_UNAUTHORIZED (401)</code>: Client is not authorized to visit this page</li>
<li><code>HTTP_FORBIDDEN (403)</code>: Permission denied</li>
<li><code>HTTP_NOT_FOUND (404)</code>: File not found</li>
<li><code>HTTP_INTERNAL_SERVER_ERROR (500)</code>: Internal server error (self explanatory)</li>
</ul>


<h3><a name="functions" id="functions">Some useful functions you should know</a></h3>

</li>


</ul>


<h3><a name="memory" id="memory">Memory management</a></h3>
<p>
Managing your resources in Apache HTTP Server 2.4 is quite easy, thanks to the memory pool 
system. In essence, each server, connection and request have their own 
memory pool that gets cleaned up when its scope ends, e.g. when a request 
is done or when a server process shuts down. All your module needs to do is 
latch onto this memory pool, and you won't have to worry about having to 
clean up after yourself - pretty neat, huh?
</p>

<p>
In our module, we will primarily be allocating memory for each request, so 
it's appropriate to use the <code>r-&gt;pool</code> 
reference when creating new objects. A few of the functions for allocating 
memory within a pool are:
</p>
<ul>
<li><code>void* <a href="http://apr.apache.org/docs/apr/1.4/group__apr__pools.html#ga85f1e193c31d109affda72f9a92c6915">apr_palloc</a>(
apr_pool_t *p, apr_size_t size)</code>: Allocates <code>size</code> number of bytes in the pool for you</li>
<li><code>void* <a href="http://apr.apache.org/docs/apr/1.4/group__apr__pools.html#gaf61c098ad258069d64cdf8c0a9369f9e">apr_pcalloc</a>(
apr_pool_t *p, apr_size_t size)</code>: Allocates <code>size</code> number of bytes in the pool for you and sets all bytes to 0</li>
<li><code>char* <a href="http://apr.apache.org/docs/apr/1.4/group__apr__strings.html#gabc79e99ff19abbd7cfd18308c5f85d47">apr_pstrdup</a>(
apr_pool_t *p, const char *s)</code>: Creates a duplicate of the string <code>s</code>. This is useful for copying constant values so you can edit them</li>
<li><code>char* <a href="http://apr.apache.org/docs/apr/1.4/group__apr__strings.html#ga3eca76b8d293c5c3f8021e45eda813d8">apr_psprintf</a>(
apr_pool_t *p, const char *fmt, ...)</code>: Similar to <code>sprintf</code>, except the server supplies you with an appropriately allocated target variable</li>
</ul>

<p>Let's put these functions into an example handler:</p>



<pre class="prettyprint lang-c">static int example_handler(request_rec *r)
{
    const char *original = "You can't edit this!";
    char *copy;
    int *integers;
    
    /* Allocate space for 10 integer values and set them all to zero. */
    integers = apr_pcalloc(r-&gt;pool, sizeof(int)*10); 
    
    /* Create a copy of the 'original' variable that we can edit. */
    copy = apr_pstrdup(r-&gt;pool, original);
    return OK;
}</pre>



<p>
This is all well and good for our module, which won't need any 
pre-initialized variables or structures. However, if we wanted to 
initialize something early on, before the requests come rolling in, we 
could simply add a call to a function in our <code>register_hooks</code> 
function to sort it out:
</p>


<pre class="prettyprint lang-c">static void register_hooks(apr_pool_t *pool)
{
    /* Call a function that initializes some stuff */
    example_init_function(pool);
    /* Create a hook in the request handler, so we get called when a request arrives */
    ap_hook_handler(example_handler, NULL, NULL, APR_HOOK_LAST);
}</pre>



<p>
In this pre-request initialization function we would not be using the 
same pool as we did when allocating resources for request-based functions. 
Instead, we would use the pool given to us by the server for allocating memory 
on a per-process based level.
</p>


<h3><a name="parsing" id="parsing">Parsing request data</a></h3>
<p>
In our example module, we would like to add a feature, that checks which 
type of digest, MD5 or SHA1 the client would like to see. This could be 
solved by adding a query string to the request. A query string is typically 
comprised of several keys and values put together in a string, for instance 
<code>valueA=yes&amp;valueB=no&amp;valueC=maybe</code>. It is up to the 
module itself to parse these and get the data it requires. In our example, 
we'll be looking for a key called <code>digest</code>, and if set to <code>
md5</code>, we'll produce an MD5 digest, otherwise we'll produce a SHA1 
digest.
</p>
<p>
Since the introduction of Apache HTTP Server 2.4, parsing request data from GET and 
POST requests have never been easier. All we require to parse both GET and 
POST data is four simple lines:
</p> 



<pre class="prettyprint lang-c">
<a href="http://ci.apache.org/projects/httpd/trunk/doxygen/group__apr__tables.html#gad7ea82d6608a4a633fc3775694ab71e4">apr_table_t</a> *GET; <em>
</em><a href="http://ci.apache.org/projects/httpd/trunk/doxygen/structapr__array__header__t.html">apr_array_header_t</a>*POST; 
<em>
</em>
<a href="http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__SCRIPT.html#gaed25877b529623a4d8f99f819ba1b7bd">
ap_args_to_table</a>(r, &amp;GET); <em>
</em><a href="http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__DAEMON.html#ga9d426b6382b49754d4f87c55f65af202">
ap_parse_form_data</a>(r, NULL, &amp;POST, -1, 8192);</pre>



<p>
In our specific example module, we're looking for the <code>digest</code> 
value from the query string, which now resides inside a table called <code>
GET</code>. To extract this value, we need only perform a simple operation:
</p>



<pre class="prettyprint lang-c">/* Get the "digest" key from the query string, if any. */
const char *digestType = apr_table_get(GET, "digest");

/* If no key was returned, we will set a default value instead. */
if (!digestType) digestType = "sha1";</pre>



<p>
The structures used for the POST and GET data are not exactly the same, so 
if we were to fetch a value from POST data instead of the query string, we 
would have to resort to a few more lines, as outlined in <a href="#get_post">this example</a> in the last chapter of this document.
</p>


<h3><a name="advanced_handler" id="advanced_handler">Making an advanced handler</a></h3>
<p>
Now that we have learned how to parse form data and manage our resources, 
we can move on to creating an advanced version of our module, that spits 
out the MD5 or SHA1 digest of files:
</p>



<pre class="prettyprint lang-c">static int example_handler(request_rec *r)
{
    int rc, exists;
    apr_finfo_t finfo;
    apr_file_t *file;

    apr_size_t readBytes;
    int n;
    apr_table_t *GET;
    apr_array_header_t *POST;
    const char *digestType;
    
    
    /* Check that the "example-handler" handler is being called. */
    if (!r-&gt;handler || strcmp(r-&gt;handler, "example-handler")) return (DECLINED);
    
    /* Figure out which file is being requested by removing the .sum from it */
    filename = apr_pstrdup(r-&gt;pool, r-&gt;filename);
    filename[strlen(filename)-4] = 0; /* Cut off the last 4 characters. */
    
    /* Figure out if the file we request a sum on exists and isn't a directory */
    rc = apr_stat(&amp;finfo, filename, APR_FINFO_MIN, r-&gt;pool);
    if (rc == APR_SUCCESS) {
        exists =
        (
            (finfo.filetype != APR_NOFILE)
        &amp;&amp;  !(finfo.filetype &amp; APR_DIR)
        );
        if (!exists) return HTTP_NOT_FOUND; /* Return a 404 if not found. */
    }
    /* If apr_stat failed, we're probably not allowed to check this file. */
    else return HTTP_FORBIDDEN;
    
    /* Parse the GET and, optionally, the POST data sent to us */
    
    ap_args_to_table(r, &amp;GET);
    ap_parse_form_data(r, NULL, &amp;POST, -1, 8192);
    
    /* Set the appropriate content type */
    ap_set_content_type(r, "text/html");
    
    /* Print a title and some general information */
    ap_rprintf(r, "&lt;h2&gt;Information on %s:&lt;/h2&gt;", filename);
    ap_rprintf(r, "&lt;b&gt;Size:&lt;/b&gt; %u bytes&lt;br/&gt;", finfo.size);
    
    /* Get the digest type the client wants to see */
    digestType = apr_table_get(GET, "digest");
    if (!digestType) digestType = "MD5";
    
    
    rc = apr_file_open(&amp;file, filename, APR_READ, APR_OS_DEFAULT, r-&gt;pool);
    if (rc == APR_SUCCESS) {
        
        /* Are we trying to calculate the MD5 or the SHA1 digest? */
        if (!strcasecmp(digestType, "md5")) {
            /* Calculate the MD5 sum of the file */
            union {
                char      chr[16];

            for (n = 0; n &lt; APR_MD5_DIGESTSIZE/4; n++) {
                ap_rprintf(r, "%08x", digest.num[n]);
            }
            ap_rputs("&lt;/code&gt;", r);
            /* Print a link to the SHA1 version */
            ap_rputs("&lt;br/&gt;&lt;a href='?digest=sha1'&gt;View the SHA1 hash instead&lt;/a&gt;", r);

<h2><a name="configuration" id="configuration">Adding configuration options</a></h2>
<p>
In this next segment of this document, we will turn our eyes away from the 
digest module and create a new example module, whose only function is to 
write out its own configuration. The purpose of this is to examine how 
the server works with configuration, and what happens when you start writing 
advanced configurations 
for your modules.
</p>
<h3><a name="config_intro" id="config_intro">An introduction to configuration 
directives</a></h3>
<p>
If you are reading this, then you probably already know 
what a configuration directive is. Simply put, a directive is a way of 
telling an individual module (or a set of modules) how to behave, such as 
these directives control how <code>mod_rewrite</code> works:
</p>
<pre class="prettyprint lang-config">RewriteEngine On
RewriteCond "%{REQUEST_URI}" "^/foo/bar"
RewriteRule "^/foo/bar/(.*)$" "/foobar?page=$1"</pre>

<p>
Each of these configuration directives are handled by a separate function, 
that parses the parameters given and sets up a configuration accordingly.
</p>

<h3><a name="config_simple" id="config_simple">Making an example configuration</a></h3>
<p>To begin with, we'll create a basic configuration in C-space:</p>



<pre class="prettyprint lang-c">typedef struct {
    int         enabled;      /* Enable or disable our module */
    const char *path;         /* Some path to...something */
    int         typeOfAction; /* 1 means action A, 2 means action B and so on */
} example_config;</pre>



<p>
Now, let's put this into perspective by creating a very small module that 
just prints out a hard-coded configuration. You'll notice that we use the 
<code>register_hooks</code> function for initializing the configuration 
values to their defaults:
</p>


<pre class="prettyprint lang-c">typedef struct {
    int         enabled;      /* Enable or disable our module */
    const char *path;         /* Some path to...something */
    int         typeOfAction; /* 1 means action A, 2 means action B and so on */
} example_config;

static example_config config;

static int example_handler(request_rec *r)
{
    if (!r-&gt;handler || strcmp(r-&gt;handler, "example-handler")) return(DECLINED);
    ap_set_content_type(r, "text/plain");
    ap_rprintf(r, "Enabled: %u\n", config.enabled);
    ap_rprintf(r, "Path: %s\n", config.path);
    ap_rprintf(r, "TypeOfAction: %x\n", config.typeOfAction);
    return OK;
}

static void register_hooks(apr_pool_t *pool) 
{
    config.enabled = 1;
    config.path = "/foo/bar";
    config.typeOfAction = 0x00;
    ap_hook_handler(example_handler, NULL, NULL, APR_HOOK_LAST);
}

/* Define our module as an entity and assign a function for registering hooks  */

module AP_MODULE_DECLARE_DATA   example_module =
{
    STANDARD20_MODULE_STUFF,
    NULL,            /* Per-directory configuration handler */
    NULL,            /* Merge handler for per-directory configurations */
    NULL,            /* Per-server configuration handler */
    NULL,            /* Merge handler for per-server configurations */
    NULL,            /* Any directives we may have for httpd */
    register_hooks   /* Our hook registering function */
};</pre>



<p>
So far so good. To access our new handler, we could add the following to 
our configuration:
</p>
<pre class="prettyprint lang-config">&lt;Location "/example"&gt;
    SetHandler example-handler
&lt;/Location&gt;</pre>

<p>
When we visit, we'll see our current configuration being spit out by our 
module. 
</p>


<h3><a name="register_directive" id="register_directive">Registering directives with the server</a></h3>
<p>
What if we want to change our configuration, not by hard-coding new values 
into the module, but by using either the httpd.conf file or possibly a 
.htaccess file? It's time to let the server know that we want this to be 
possible. To do so, we must first change our <em>name tag</em> to include a 
reference to the configuration directives we want to register with the server:
</p>


<pre class="prettyprint lang-c">module AP_MODULE_DECLARE_DATA   example_module =
{
    STANDARD20_MODULE_STUFF,
    NULL,               /* Per-directory configuration handler */
    NULL,               /* Merge handler for per-directory configurations */
    NULL,               /* Per-server configuration handler */
    NULL,               /* Merge handler for per-server configurations */
    example_directives, /* Any directives we may have for httpd */
    register_hooks      /* Our hook registering function */
};</pre>



<p>
This will tell the server that we are now accepting directives from the 
configuration files, and that the structure called <code>example_directives
</code> holds information on what our directives are and how they work. 
Since we have three different variables in our module configuration, we 
will add a structure with three directives and a NULL at the end:
</p>


<pre class="prettyprint lang-c">static const command_rec        example_directives[] =
{
    AP_INIT_TAKE1("exampleEnabled", example_set_enabled, NULL, RSRC_CONF, "Enable or disable mod_example"),
    AP_INIT_TAKE1("examplePath", example_set_path, NULL, RSRC_CONF, "The path to whatever"),
    AP_INIT_TAKE2("exampleAction", example_set_action, NULL, RSRC_CONF, "Special action value!"),
    { NULL }
};</pre>



<p>
<img src="../images/build_a_mod_4.png" alt="Directives structure" /><br />
As you can see, each directive needs at least 5 parameters set:
</p>
<ol>
<li><code><a href="http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__CONFIG.html#ga07c7d22ae17805e61204463326cf9c34">AP_INIT_TAKE1</a></code>: This is a macro that tells the server that this directive takes one and only one argument. 
If we required two arguments, we could use the macro <code><a href="http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__CONFIG.html#gafaec43534fcf200f37d9fecbf9247c21">AP_INIT_TAKE2</a></code> and so on (refer to httpd_conf.h 
for more macros).</li>
<li><code>exampleEnabled</code>: This is the name of our directive. More precisely, it is what the user must put in his/her 
configuration in order to invoke a configuration change in our module.</li>
<li><code>example_set_enabled</code>: This is a reference to a C function that parses the directive and sets the configuration 
accordingly. We will discuss how to make this in the following paragraph.</li>
<li><code>RSRC_CONF</code>: This tells the server where the directive is permitted. We'll go into details on this value in the 
later chapters, but for now, <code>RSRC_CONF</code> means that the server will only accept these directives in a server context.</li>
<li><code>"Enable or disable...."</code>: This is simply a brief description of what the directive does.</li>
</ol>
<p>
(<em>The "missing" parameter in our definition, which is usually set to 
<code>NULL</code>, is an optional function that can be run after the 
initial function to parse the arguments have been run. This is usually 
omitted, as the function for verifying arguments might as well be used to 
set them.</em>)
</p>

<h3><a name="directive_handler" id="directive_handler">The directive handler function</a></h3>
<p>
Now that we have told the server to expect some directives for our module, it's 
time to make a few functions for handling these. What the server reads in the 
configuration file(s) is text, and so naturally, what it passes along to 
our directive handler is one or more strings, that we ourselves need to 
recognize and act upon. You'll notice, that since we set our <code>
exampleAction</code> directive to accept two arguments, its C function also 
has an additional parameter defined:</p> 


<pre class="prettyprint lang-c">/* Handler for the "exampleEnabled" directive */
const char *example_set_enabled(cmd_parms *cmd, void *cfg, const char *arg)
{
    if(!strcasecmp(arg, "on")) config.enabled = 1;
    else config.enabled = 0;
    return NULL;
}

/* Handler for the "examplePath" directive */
const char *example_set_path(cmd_parms *cmd, void *cfg, const char *arg)
{
    config.path = arg;
    return NULL;
}

/* Handler for the "exampleAction" directive */
/* Let's pretend this one takes one argument (file or db), and a second (deny or allow), */
/* and we store it in a bit-wise manner. */
const char *example_set_action(cmd_parms *cmd, void *cfg, const char *arg1, const char *arg2)
{
    if(!strcasecmp(arg1, "file")) config.typeOfAction = 0x01;
    else config.typeOfAction = 0x02;
    
    if(!strcasecmp(arg2, "deny")) config.typeOfAction += 0x10;
    else config.typeOfAction += 0x20;
    return NULL;
}</pre>





<h3><a name="directive_complete" id="directive_complete">Putting it all together</a></h3>
<p>
Now that we have our directives set up, and handlers configured for them, 
we can assemble our module into one big file:
</p>

<p>
In our httpd.conf file, we can now change the hard-coded configuration by 
adding a few lines:
</p>
<pre class="prettyprint lang-config">ExampleEnabled On
ExamplePath "/usr/bin/foo"
ExampleAction file allow</pre>

<p>
And thus we apply the configuration, visit <code>/example</code> on our 
web site, and we see the configuration has adapted to what we wrote in our 
configuration file.
</p>



</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="context" id="context">Context aware configurations</a></h2>
<h3><a name="context_intro" id="context_intro">Introduction to context aware configurations</a></h3>
<p>
In Apache HTTP Server 2.4, different URLs, virtual hosts, directories etc can have very 
different meanings to the user of the server, and thus different contexts 
within which modules must operate. For example, let's assume you have this 
configuration set up for mod_rewrite:
</p>
<pre class="prettyprint lang-config">&lt;Directory "/var/www"&gt;
    RewriteCond "%{HTTP_HOST}" "^example.com$"
    RewriteRule "(.*)" "http://www.example.com/$1"
&lt;/Directory&gt;
&lt;Directory "/var/www/sub"&gt;
    RewriteRule "^foobar$" "index.php?foobar=true"
&lt;/Directory&gt;</pre>

<p>
In this example, you will have set up two different contexts for 
mod_rewrite:</p>
<ol>
<li>Inside <code>/var/www</code>, all requests for <code>http://example.com</code> must go to <code>http://www.example.com</code></li>
<li>Inside <code>/var/www/sub</code>, all requests for <code>foobar</code> must go to <code>index.php?foobar=true</code></li>
</ol>
<p>
If mod_rewrite (or the entire server for that matter) wasn't context aware, then 
these rewrite rules would just apply to every and any request made, 
regardless of where and how they were made, but since the module can pull 
the context specific configuration straight from the server, it does not need 
to know itself, which of the directives are valid in this context, since 
the server takes care of this.</p>

<p>
So how does a module get the specific configuration for the server, 
directory or location in question? It does so by making one simple call:
</p>


<pre class="prettyprint lang-c">example_config *config = (example_config*) <a href="http://ci.apache.org/projects/httpd/trunk/doxygen/group__APACHE__CORE__CONFIG.html#ga1093a5908a384eacc929b028c79f2a02">ap_get_module_config</a>(r-&gt;per_dir_config, &amp;example_module);</pre>



<p>
That's it! Of course, a whole lot goes on behind the scenes, which we will 
discuss in this chapter, starting with how the server came to know what our 
configuration looks like, and how it came to be set up as it is in the 
specific context.
</p>


<h3><a name="context_base" id="context_base">Our basic configuration setup</a></h3>
<p>In this chapter, we will be working with a slightly modified version of 
our previous context structure. We will set a <code>context</code> 
variable that we can use to track which context configuration is being 
used by the server in various places:
</p>

<pre class="prettyprint lang-c">typedef struct {
    char        context[256];
    char        path[256];
    int         typeOfAction;
    int         enabled;
} example_config;</pre>



<p>Our handler for requests will also be modified, yet still very simple:</p>



<pre class="prettyprint lang-c">static int example_handler(request_rec *r)
{
    if(!r-&gt;handler || strcmp(r-&gt;handler, "example-handler")) return(DECLINED);
    example_config *config = (example_config*) ap_get_module_config(r-&gt;per_dir_config, &amp;example_module);
    ap_set_content_type(r, "text/plain");
    ap_rprintf("Enabled: %u\n", config-&gt;enabled);
    ap_rprintf("Path: %s\n", config-&gt;path);
    ap_rprintf("TypeOfAction: %x\n", config-&gt;typeOfAction);
    ap_rprintf("Context: %s\n", config-&gt;context);
    return OK;
}</pre>





<h3><a name="context_which" id="context_which">Choosing a context</a></h3>
<p>
Before we can start making our module context aware, we must first define, 
which contexts we will accept. As we saw in the previous chapter, defining 
a directive required five elements be set:</p>



<pre class="prettyprint lang-c">AP_INIT_TAKE1("exampleEnabled", example_set_enabled, NULL, RSRC_CONF, "Enable or disable mod_example"),</pre>




<p>The <code>RSRC_CONF</code> definition told the server that we would only allow 
this directive in a global server context, but since we are now trying out 
a context aware version of our module, we should set this to something 
more lenient, namely the value <code>ACCESS_CONF</code>, which lets us use 
the directive inside &lt;Directory&gt; and &lt;Location&gt; blocks. For more 
control over the placement of your directives, you can combine the following 
restrictions together to form a specific rule:
</p>
<ul>
<li><code>RSRC_CONF</code>: Allow in .conf files (not .htaccess) outside &lt;Directory&gt; or &lt;Location&gt;</li>
<li><code>ACCESS_CONF</code>: Allow in .conf files (not .htaccess) inside &lt;Directory&gt; or &lt;Location&gt;</li>
<li><code>OR_OPTIONS</code>: Allow in .conf files and .htaccess when <code>AllowOverride Options</code> is set</li>
<li><code>OR_FILEINFO</code>: Allow in .conf files and .htaccess when <code>AllowOverride FileInfo</code> is set</li>
<li><code>OR_AUTHCFG</code>: Allow in .conf files and .htaccess when <code>AllowOverride AuthConfig</code> is set</li>
<li><code>OR_INDEXES</code>: Allow in .conf files and .htaccess when <code>AllowOverride Indexes</code> is set</li>
<li><code>OR_ALL</code>: Allow anywhere in .conf files and .htaccess</li>
</ul>


<h3><a name="context_pool" id="context_pool">Using the server to allocate configuration slots</a></h3>
<p> A much smarter way to manage your configurations is by letting the server 
help you create them. To do so, we must first start off by changing our 
<em>name tag</em> to let the server know, that it should assist us in creating 
and managing our configurations. Since we have chosen the per-directory 
(or per-location) context for our module configurations, we'll add a 
per-directory creator and merger function reference in our tag:</p>


<pre class="prettyprint lang-c">module AP_MODULE_DECLARE_DATA   example_module =
{
    STANDARD20_MODULE_STUFF,
    create_dir_conf, /* Per-directory configuration handler */
    merge_dir_conf,  /* Merge handler for per-directory configurations */
    NULL,            /* Per-server configuration handler */
    NULL,            /* Merge handler for per-server configurations */
    directives,      /* Any directives we may have for httpd */
    register_hooks   /* Our hook registering function */
};</pre>







<h3><a name="context_new" id="context_new">Creating new context configurations</a></h3>
<p>
Now that we have told the server to help us create and manage configurations, 
our first step is to make a function for creating new, blank 
configurations. We do so by creating the function we just referenced in 
our name tag as the Per-directory configuration handler:</p>

<pre class="prettyprint lang-c">void *create_dir_conf(apr_pool_t *pool, char *context) {
    context = context ? context : "(undefined context)";
    example_config *cfg = apr_pcalloc(pool, sizeof(example_config));
    if(cfg) {
        /* Set some default values */
        strcpy(cfg-&gt;context, context);
        cfg-&gt;enabled = 0;
        cfg-&gt;path = "/foo/bar";
        cfg-&gt;typeOfAction = 0x11;
    }
    return cfg;
}</pre>






<h3><a name="context_merge" id="context_merge">Merging configurations</a></h3>
<p>
Our next step in creating a context aware configuration is merging 
configurations. This part of the process particularly applies to scenarios 
where you have a parent configuration and a child, such as the following: 
</p>
<pre class="prettyprint lang-config">&lt;Directory "/var/www"&gt;
    ExampleEnabled On
    ExamplePath "/foo/bar"
    ExampleAction file allow
&lt;/Directory&gt;
&lt;Directory "/var/www/subdir"&gt;
    ExampleAction file deny
&lt;/Directory&gt;</pre>

<p>
In this example, it is natural to assume that the directory <code>
/var/www/subdir</code> should inherit the values set for the <code>/var/www
</code> directory, as we did not specify an <code>ExampleEnabled</code> nor 
an <code>ExamplePath</code> for this directory. The server does not presume to 
know if this is true, but cleverly does the following:
</p>
<ol>
<li>Creates a new configuration for <code>/var/www</code></li>
<li>Sets the configuration values according to the directives given for <code>/var/www</code></li>
<li>Creates a new configuration for <code>/var/www/subdir</code></li>
<li>Sets the configuration values according to the directives given for <code>/var/www/subdir</code></li>
<li><strong>Proposes a merge</strong> of the two configurations into a new configuration for <code>/var/www/subdir</code></li>
</ol>
<p>
This proposal is handled by the <code>merge_dir_conf</code> function we 
referenced in our name tag. The purpose of this function is to assess the 
two configurations and decide how they are to be merged:</p>



<pre class="prettyprint lang-c">void *merge_dir_conf(apr_pool_t *pool, void *BASE, void *ADD) {
    example_config *base = (example_config *) BASE ; /* This is what was set in the parent context */
    example_config *add = (example_config *) ADD ;   /* This is what is set in the new context */
    example_config *conf = (example_config *) create_dir_conf(pool, "Merged configuration"); /* This will be the merged configuration */
    
    /* Merge configurations */
    conf-&gt;enabled = ( add-&gt;enabled == 0 ) ? base-&gt;enabled : add-&gt;enabled ;
    conf-&gt;typeOfAction = add-&gt;typeOfAction ? add-&gt;typeOfAction : base-&gt;typeOfAction;
    strcpy(conf-&gt;path, strlen(add-&gt;path) ? add-&gt;path : base-&gt;path);
    
    return conf ;
}</pre>






<h3><a name="context_example" id="context_example">Trying out our new context aware configurations</a></h3>
<p>
Now, let's try putting it all together to create a new module that is 
context aware. First off, we'll create a configuration that lets us test 
how the module works:
</p>
<pre class="prettyprint lang-config">&lt;Location "/a"&gt;
    SetHandler example-handler
    ExampleEnabled on
    ExamplePath "/foo/bar"
    ExampleAction file allow
&lt;/Location&gt;

&lt;Location "/a/b"&gt;
    ExampleAction file deny
    ExampleEnabled off
&lt;/Location&gt;

&lt;Location "/a/b/c"&gt;
    ExampleAction db deny
    ExamplePath "/foo/bar/baz"
    ExampleEnabled on
&lt;/Location&gt;</pre>

<p>
Then we'll assemble our module code. Note, that since we are now using our 
name tag as reference when fetching configurations in our handler, I have 
added some prototypes to keep the compiler happy:
</p>

configuring them. What you do next is entirely up to you, but it is my 
hope that something valuable has come out of reading this documentation.

    <p>There are a number of common pitfalls encountered when writing
    output filters; this page aims to document best practice for
    authors of new or existing filters.</p>

    <p>This document is applicable to both version 2.0 and version 2.2
    of the Apache HTTP Server; it specifically targets
    <code>RESOURCE</code>-level or <code>CONTENT_SET</code>-level
    filters though some advice is generic to all types of filter.</p>

<h2><a name="basics" id="basics">Filters and bucket brigades</a></h2>
    

    <p>Each time a filter is invoked, it is passed a <em>bucket
    brigade</em>, containing a sequence of <em>buckets</em> which
    represent both data content and metadata.  Every bucket has a
    <em>bucket type</em>; a number of bucket types are defined and
    used by the <code>httpd</code> core modules (and the
    <code>apr-util</code> library which provides the bucket brigade
    interface), but modules are free to define their own types.</p>

    <div class="note">Output filters must be prepared to process
    buckets of non-standard types; with a few exceptions, a filter
    need not care about the types of buckets being filtered.</div>

    <p>A filter can tell whether a bucket represents either data or
    metadata using the <code>APR_BUCKET_IS_METADATA</code> macro.
    Generally, all metadata buckets should be passed down the filter
    chain by an output filter.  Filters may transform, delete, and
    insert data buckets as appropriate.</p>

    <p>There are two metadata bucket types which all filters must pay
    attention to: the <code>EOS</code> bucket type, and the
    <code>FLUSH</code> bucket type.  An <code>EOS</code> bucket
    indicates that the end of the response has been reached and no
    further buckets need be processed.  A <code>FLUSH</code> bucket
    indicates that the filter should flush any buffered buckets (if
    applicable) down the filter chain immediately.</p>

    <div class="note"><code>FLUSH</code> buckets are sent when the
    content generator (or an upstream filter) knows that there may be
    a delay before more content can be sent.  By passing
    <code>FLUSH</code> buckets down the filter chain immediately,
    filters ensure that the client is not kept waiting for pending
    data longer than necessary.</div>

    <p>Filters can create <code>FLUSH</code> buckets and pass these
    down the filter chain if desired.  Generating <code>FLUSH</code>
    buckets unnecessarily, or too frequently, can harm network
    utilisation since it may force large numbers of small packets to
    be sent, rather than a small number of larger packets.  The
    section on <a href="#nonblock">Non-blocking bucket reads</a>
    covers a case where filters are encouraged to generate
    <code>FLUSH</code> buckets.</p>

    <div class="example"><h3>Example bucket brigade</h3><p><code>
    HEAP FLUSH FILE EOS</code></p></div>

    <p>This shows a bucket brigade which may be passed to a filter; it
    contains two metadata buckets (<code>FLUSH</code> and
    <code>EOS</code>), and two data buckets (<code>HEAP</code> and
    <code>FILE</code>).</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="invocation" id="invocation">Filter invocation</a></h2>
    

    <p>For any given request, an output filter might be invoked only
    once and be given a single brigade representing the entire response.
    It is also possible that the number of times a filter is invoked
    for a single response is proportional to the size of the content
    being filtered, with the filter being passed a brigade containing
    a single bucket each time.  Filters must operate correctly in
    either case.</p>

    <div class="warning">An output filter which allocates long-lived
    memory every time it is invoked may consume memory proportional to
    response size.  Output filters which need to allocate memory
    should do so once per response; see <a href="#state">Maintaining
    state</a> below.</div>

    <p>An output filter can distinguish the final invocation for a
    given response by the presence of an <code>EOS</code> bucket in
    the brigade.  Any buckets in the brigade after an EOS should be
    ignored.</p>

    <p>An output filter should never pass an empty brigade down the
    filter chain.  To be defensive, filters should be prepared to
    accept an empty brigade, and should return success without passing
    this brigade on down the filter chain.  The handling of an empty
    brigade should have no side effects (such as changing any state
    private to the filter).</p>

    <div class="example"><h3>How to handle an empty brigade</h3><pre class="prettyprint lang-c">apr_status_t dummy_filter(ap_filter_t *f, apr_bucket_brigade *bb)
{
    if (APR_BRIGADE_EMPTY(bb)) {
        return APR_SUCCESS;
    }
    ...</pre>
</div>

<div class="section">
<h2><a name="brigade" id="brigade">Brigade structure</a></h2>
    

    <p>A bucket brigade is a doubly-linked list of buckets.  The list
    is terminated (at both ends) by a <em>sentinel</em> which can be
    distinguished from a normal bucket by comparing it with the
    pointer returned by <code>APR_BRIGADE_SENTINEL</code>.  The list
    sentinel is in fact not a valid bucket structure; any attempt to
    call normal bucket functions (such as
    <code>apr_bucket_read</code>) on the sentinel will have undefined
    behaviour (i.e. will crash the process).</p>

    <p>There are a variety of functions and macros for traversing and
    manipulating bucket brigades; see the <a href="http://apr.apache.org/docs/apr-util/trunk/group___a_p_r___util___bucket___brigades.html">apr_buckets.h</a>
    header for complete coverage.  Commonly used macros include:</p>

    <dl>
      <dt><code>APR_BRIGADE_FIRST(bb)</code></dt>
      <dd>returns the first bucket in brigade bb</dd>

      <dt><code>APR_BRIGADE_LAST(bb)</code></dt>
      <dd>returns the last bucket in brigade bb</dd>

      <dt><code>APR_BUCKET_NEXT(e)</code></dt>
      <dd>gives the next bucket after bucket e</dd>

      <dt><code>APR_BUCKET_PREV(e)</code></dt>
      <dd>gives the bucket before bucket e</dd>

    </dl>

    <p>The <code>apr_bucket_brigade</code> structure itself is
    allocated out of a pool, so if a filter creates a new brigade, it
    must ensure that memory use is correctly bounded.  A filter which
    allocates a new brigade out of the request pool
    (<code>r-&gt;pool</code>) on every invocation, for example, will fall
    foul of the <a href="#invocation">warning above</a> concerning
    memory use.  Such a filter should instead create a brigade on the
    first invocation per request, and store that brigade in its <a href="#state">state structure</a>.</p>

    <div class="warning"><p>It is generally never advisable to use
    <code>apr_brigade_destroy</code> to "destroy" a brigade unless
    you know for certain that the brigade will never be used
    again, even then, it should be used rarely.  The
    memory used by the brigade structure will not be released by
    calling this function (since it comes from a pool), but the
    associated pool cleanup is unregistered.  Using
    <code>apr_brigade_destroy</code> can in fact cause memory leaks;
    if a "destroyed" brigade contains buckets when its
    containing pool is destroyed, those buckets will <em>not</em> be
    immediately destroyed.</p>

    <p>In general, filters should use <code>apr_brigade_cleanup</code>
    in preference to <code>apr_brigade_destroy</code>.</p></div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="buckets" id="buckets">Processing buckets</a></h2>

    

    <p>When dealing with non-metadata buckets, it is important to
    understand that the "<code>apr_bucket *</code>" object is an
    abstract <em>representation</em> of data:</p>

    <ol>
      <li>The amount of data represented by the bucket may or may not
      have a determinate length; for a bucket which represents data of
      indeterminate length, the <code>-&gt;length</code> field is set to
      the value <code>(apr_size_t)-1</code>.  For example, buckets of
      the <code>PIPE</code> bucket type have an indeterminate length;
      they represent the output from a pipe.</li>

      <li>The data represented by a bucket may or may not be mapped
      into memory.  The <code>FILE</code> bucket type, for example,
      represents data stored in a file on disk.</li>
    </ol>

    <p>Filters read the data from a bucket using the
    <code>apr_bucket_read</code> function.  When this function is
    invoked, the bucket may <em>morph</em> into a different bucket
    type, and may also insert a new bucket into the bucket brigade.
    This must happen for buckets which represent data not mapped into
    memory.</p>

    <p>To give an example; consider a bucket brigade containing a
    single <code>FILE</code> bucket representing an entire file, 24
    kilobytes in size:</p>

    <div class="example"><p><code>FILE(0K-24K)</code></p></div>

    <p>When this bucket is read, it will read a block of data from the
    file, morph into a <code>HEAP</code> bucket to represent that
    data, and return the data to the caller.  It also inserts a new
    <code>FILE</code> bucket representing the remainder of the file;
    after the <code>apr_bucket_read</code> call, the brigade looks
    like:</p>

    <div class="example"><p><code>HEAP(8K) FILE(8K-24K)</code></p></div>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="filtering" id="filtering">Filtering brigades</a></h2>
    

    <p>The basic function of any output filter will be to iterate
    through the passed-in brigade and transform (or simply examine)
    the content in some manner.  The implementation of the iteration
    loop is critical to producing a well-behaved output filter.</p>

    <p>Taking an example which loops through the entire brigade as
    follows:</p>

    <div class="example"><h3>Bad output filter -- do not imitate!</h3><pre class="prettyprint lang-c">apr_bucket *e = APR_BRIGADE_FIRST(bb);
const char *data;
apr_size_t length;

while (e != APR_BRIGADE_SENTINEL(bb)) {
    apr_bucket_read(e, &amp;data, &amp;length, APR_BLOCK_READ);
    e = APR_BUCKET_NEXT(e);
}

return ap_pass_brigade(bb);</pre>
</div>

    <p>The above implementation would consume memory proportional to
    content size.  If passed a <code>FILE</code> bucket, for example,
    the entire file contents would be read into memory as each
    <code>apr_bucket_read</code> call morphed a <code>FILE</code>
    bucket into a <code>HEAP</code> bucket.</p>

    <p>In contrast, the implementation below will consume a fixed
    amount of memory to filter any brigade; a temporary brigade is
    needed and must be allocated only once per response, see the <a href="#state">Maintaining state</a> section.</p>

    <div class="example"><h3>Better output filter</h3><pre class="prettyprint lang-c">apr_bucket *e;

<h2><a name="state" id="state">Maintaining state</a></h2>

    

    <p>A filter which needs to maintain state over multiple
    invocations per response can use the <code>-&gt;ctx</code> field of
    its <code>ap_filter_t</code> structure.  It is typical to store a
    temporary brigade in such a structure, to avoid having to allocate
    a new brigade per invocation as described in the <a href="#brigade">Brigade structure</a> section.</p>

    <div class="example"><h3>Example code to maintain filter state</h3><pre class="prettyprint lang-c">struct dummy_state {
    apr_bucket_brigade *tmpbb;

{

    state = f-&gt;ctx;
    if (state == NULL) {

        /* First invocation for this response: initialise state structure.

<div class="section">
<h2><a name="buffer" id="buffer">Buffering buckets</a></h2>
    

    <p>If a filter decides to store buckets beyond the duration of a
    single filter function invocation (for example storing them in its
    <code>-&gt;ctx</code> state structure), those buckets must be <em>set
    aside</em>.  This is necessary because some bucket types provide
    buckets which represent temporary resources (such as stack memory)
    which will fall out of scope as soon as the filter chain completes
    processing the brigade.</p>

    <p>To setaside a bucket, the <code>apr_bucket_setaside</code>
    function can be called.  Not all bucket types can be setaside, but
    if successful, the bucket will have morphed to ensure it has a
    lifetime at least as long as the pool given as an argument to the
    <code>apr_bucket_setaside</code> function.</p>

    <p>Alternatively, the <code>ap_save_brigade</code> function can be
    used, which will move all the buckets into a separate brigade
    containing buckets with a lifetime as long as the given pool
    argument.  This function must be used with care, taking into
    account the following points:</p>

    <ol>
      <li>On return, <code>ap_save_brigade</code> guarantees that all
      the buckets in the returned brigade will represent data mapped
      into memory.  If given an input brigade containing, for example,
      a <code>PIPE</code> bucket, <code>ap_save_brigade</code> will
      consume an arbitrary amount of memory to store the entire output
      of the pipe.</li>

      <li>When <code>ap_save_brigade</code> reads from buckets which
      cannot be setaside, it will always perform blocking reads,
      removing the opportunity to use <a href="#nonblock">Non-blocking
      bucket reads</a>.</li>

      <li>If <code>ap_save_brigade</code> is used without passing a
      non-NULL "<code>saveto</code>" (destination) brigade parameter,
      the function will create a new brigade, which may cause memory
      use to be proportional to content size as described in the <a href="#brigade">Brigade structure</a> section.</li>
    </ol>

    <div class="warning">Filters must ensure that any buffered data is
    processed and passed down the filter chain during the last
    invocation for a given response (a brigade containing an EOS
    bucket).  Otherwise such data will be lost.</div>

<div class="section">
<h2><a name="nonblock" id="nonblock">Non-blocking bucket reads</a></h2>
    

    <p>The <code>apr_bucket_read</code> function takes an
    <code>apr_read_type_e</code> argument which determines whether a
    <em>blocking</em> or <em>non-blocking</em> read will be performed
    from the data source.  A good filter will first attempt to read
    from every data bucket using a non-blocking read; if that fails
    with <code>APR_EAGAIN</code>, then send a <code>FLUSH</code>
    bucket down the filter chain, and retry using a blocking read.</p>

    <p>This mode of operation ensures that any filters further down the
    filter chain will flush any buffered buckets if a slow content
    source is being used.</p>

    <p>A CGI script is an example of a slow content source which is
    implemented as a bucket type. <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code> will send
    <code>PIPE</code> buckets which represent the output from a CGI
    script; reading from such a bucket will block when waiting for the
    CGI script to produce more output.</p>

<h2><a name="rules" id="rules">Ten rules for output filters</a></h2>
    

    <p>In summary, here is a set of rules for all output filters to
    follow:</p>

    <ol>
      <li>Output filters should not pass empty brigades down the filter
      chain, but should be tolerant of being passed empty
      brigades.</li>

      <li>Output filters must pass all metadata buckets down the filter
      chain; <code>FLUSH</code> buckets should be respected by passing
      any pending or buffered buckets down the filter chain.</li>

      <li>Output filters should ignore any buckets following an
      <code>EOS</code> bucket.</li>

      <li>Output filters must process a fixed amount of data at a
      time, to ensure that memory consumption is not proportional to
      the size of the content being filtered.</li>

      <li>Output filters should be agnostic with respect to bucket
      types, and must be able to process buckets of unfamiliar
      type.</li>

      <li>After calling <code>ap_pass_brigade</code> to pass a brigade
      down the filter chain, output filters should call
      <code>apr_brigade_cleanup</code> to ensure the brigade is empty
      before reusing that brigade structure; output filters should
      never use <code>apr_brigade_destroy</code> to "destroy"
      brigades.</li>

      <li>Output filters must <em>setaside</em> any buckets which are
      preserved beyond the duration of the filter function.</li>

      <li>Output filters must not ignore the return value of
      <code>ap_pass_brigade</code>, and must return appropriate errors
      back up the filter chain.</li>

      <li>Output filters must only create a fixed number of bucket
      brigades for each response, rather than one per invocation.</li>

      <li>Output filters should first attempt non-blocking reads from
      each data bucket, and send a <code>FLUSH</code> bucket down the
      filter chain if the read blocks, before retrying with a blocking
      read.</li>

<h2><a name="usecase1" id="usecase1">Use case: buffering in mod_ratelimit</a></h2>
    
    <p>The <a href="http://svn.apache.org/r1833875">r1833875</a> change is a good
    example to show what buffering and keeping state means in the context of an
    output filter. In this use case, a user asked on the users' mailing list a
    interesting question about why <code class="module"><a href="../mod/mod_ratelimit.html">mod_ratelimit</a></code> seemed not to
    honor its setting with proxied content (either rate limiting at a different
    speed or simply not doing it at all). Before diving deep into the solution,
    it is better to explain on a high level how <code class="module"><a href="../mod/mod_ratelimit.html">mod_ratelimit</a></code> works.
    The trick is really simple: take the rate limit settings and calculate a
    chunk size of data to flush every 200ms to the client. For example, let's imagine
    that to set <code>rate-limit 60</code> in our config, these are the high level
    steps to find the chunk size:</p>
    <pre class="prettyprint lang-c">/* milliseconds to wait between each flush of data */
RATE_INTERVAL_MS = 200;
/* rate limit speed in b/s */
speed = 60 * 1024;
/* final chunk size is 12228 bytes */
chunk_size = (speed / (1000 / RATE_INTERVAL_MS));</pre>

    <p>If we apply this calculation to a bucket brigade carrying 38400 bytes, it means
    that the filter will try to do the following:</p>
    <ol>
        <li>Split the 38400 bytes in chunks of maximum 12228 bytes each.</li>
        <li>Flush the first 12228 chunk of bytes and sleep 200ms.</li>
        <li>Flush the second 12228 chunk of bytes and sleep 200ms.</li>
        <li>Flush the third 12228 chunk of bytes and sleep 200ms.</li>
        <li>Flush the remaining 1716 bytes.</li>
    </ol>
    <p>The above pseudo code works fine if the output filter handles only one brigade
    for each response, but it might happen that it needs to be called multiple times
    with different brigade sizes as well. The former use case is for example when
    httpd directly serves some content, like a static file: the bucket brigade
    abstraction takes care of handling the whole content, and rate limiting
    works nicely. But if the same static content is served via mod_proxy_http (for
    example a backend is serving it rather than httpd) then the content generator
    (in this case mod_proxy_http) may use a maximum buffer size and then send data
    as bucket brigades to the output filters chain regularly, triggering of course
    multiple calls to <code class="module"><a href="../mod/mod_ratelimit.html">mod_ratelimit</a></code>. If the reader tries to execute the pseudo code
    assuming multiple calls to the output filter, each one requiring to process
    a bucket brigade of 38400 bytes, then it is easy to spot some
    anomalies:</p>
    <ol>
        <li>Between the last flush of a brigade and the first one of the next,
            there is no sleep.</li>
        <li>Even if the sleep was forced after the last flush, then that chunk size
            would not be the ideal size (1716 bytes instead of 12228) and the final client's speed
            would quickly become different than what set in the httpd's config.</li>
    </ol>
    <p>In this case, two things might help:</p>
    <ol>
        <li>Use the ctx internal data structure, initialized by <code class="module"><a href="../mod/mod_ratelimit.html">mod_ratelimit</a></code>
        for each response handling cycle, to "remember" when the last sleep was
        performed across multiple invocations, and act accordingly.</li>
        <li>If a bucket brigade is not splittable into a finite number of chunk_size
        blocks, store the remaining bytes (located in the tail of the bucket brigade) 
        in a temporary holding area (namely another bucket brigade) and then use
        <code>ap_save_brigade</code> to set them aside.
        These bytes will be prepended to the next bucket brigade that will be handled
        in the subsequent invocation.</li>
        <li>Avoid the previous logic if the bucket brigade that is currently being
        processed contains the end of stream bucket (EOS). There is no need to sleep
        or buffering data if the end of stream is reached.</li>
    </ol>
    <p>The commit linked in the beginning of the section contains also a bit of code
    refactoring so it is not trivial to read during the first pass, but the overall
    idea is basically what written up to now. The goal of this section is not to
    cause a headache to the reader trying to read C code, but to put him/her into
    the right mindset needed to use efficiently the tools offered by the httpd's
    filter chain toolset.</p>

<h2><a name="uptodate" id="uptodate">Maintenez votre serveur à jour</a></h2>

    <p>Le serveur HTTP Apache a une bonne réputation en matière de sécurité
    et possède une communauté de développeurs très sensibilisés aux problèmes
    de sécurité. Mais il est inévitable de trouver certains problèmes
    -- petits ou grands -- une fois le logiciel mis à disposition. C'est pour
    cette raison qu'il est crucial de se tenir informé des mises à jour. Si
    vous avez obtenu votre version du serveur HTTP directement depuis Apache,
    nous vous conseillons grandement de vous abonner à la <a href="http://httpd.apache.org/lists.html#http-announce">Liste de diffusion
    des annonces du serveur HTTP</a> qui vous informera de
    la parution des nouvelles versions et des mises à jour de sécurité. La
    plupart des distributeurs tiers d'Apache fournissent des services
    similaires.</p>

    <p>Gardez cependant à l'esprit que lorsqu'un serveur web est compromis, le
    code du serveur HTTP n'est la plupart du temps pas en cause. Les problèmes
    proviennent plutôt de code ajouté, de scripts CGI, ou du système
    d'exploitation sous-jacent. Vous devez donc vous tenir informé des
    problèmes et mises à jour concernant tous les logiciels présents sur
    votre système.</p>

<h2><a name="dos" id="dos">Attaques de type "Déni de service"
    (Denial of Service - DoS)</a></h2>

    

    <p>Tous les services réseau peuvent faire l'objet d'attaques de type
    "Déni de service" qui tentent de les empêcher de répondre aux clients en
    saturant leurs ressources. Il est impossible de se prémunir totalement
    contre ce type d'attaques, mais vous pouvez accomplir certaines actions
    afin de minimiser les problèmes qu'elles créent.</p>

    <p>Souvent, l'outil anti-DoS le plus efficace sera constitué par le
    pare-feu ou certaines configurations du système d'exploitation. Par
    exemple, la plupart des pare-feu peuvent être configurés de façon à
    limiter le nombre de connexions simultanées depuis une adresse IP ou un
    réseau, ce qui permet de prévenir toute une gamme d'attaques simples.
    Bien sûr, ceci n'est d'aucun secours contre les attaques de type
    "Déni de service" distribuées (DDoS).</p>

    <p>Certains réglages de la configuration d'Apache peuvent aussi
    minimiser les problèmes :</p>

    <ul>
      <li>La directive <code class="directive"><a href="../mod/mod_reqtimeout.html#requestreadtimeout">RequestReadTimeout</a></code> permet de
      limiter le temps que met le client pour envoyer sa requête.</li>

      <li>La valeur de la directive
      <code class="directive"><a href="../mod/core.html#timeout">TimeOut</a></code> doit être diminuée sur les
      sites sujets aux attaques DoS. Une valeur de quelques secondes devrait
      convenir. Cependant, comme <code class="directive"><a href="../mod/core.html#timeout">TimeOut</a></code>
      est actuellement concerné par de nombreuses opérations différentes, lui
      attribuer une valeur trop faible peut provoquer des problèmes avec les
      scripts CGI qui présentent un long temps de réponse.</li>

      <li>La valeur de la directive
      <code class="directive"><a href="../mod/core.html#keepalivetimeout">KeepAliveTimeout</a></code> doit aussi être
      diminuée sur les sites sujets aux attaques DoS. Certains sites
      désactivent même complètement le "maintien en vie" (keepalives)
      à l'aide de la directive
      <code class="directive"><a href="../mod/core.html#keepalive">KeepAlive</a></code>, ce qui bien sûr
      présente des inconvénients en matière de performances.</li>

      <li>Les valeurs des différentes directives fournies par d'autres modules
      et en rapport avec des délais doivent aussi être vérifiées.</li>

      <li>Les directives
      <code class="directive"><a href="../mod/core.html#limitrequestbody">LimitRequestBody</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestfields">LimitRequestFields</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestfieldsize">LimitRequestFieldSize</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestline">LimitRequestLine</a></code>, et
      <code class="directive"><a href="../mod/core.html#limitxmlrequestbody">LimitXMLRequestBody</a></code> doivent être
      configurées avec prudence afin de limiter la consommation de ressources
      induite par les demandes des clients.
      </li>

      <li>Sur les systèmes d'exploitation qui le supportent, assurez-vous que
      la directive <code class="directive"><a href="../mod/core.html#acceptfilter">AcceptFilter</a></code> est
      activée afin de déléguer une partie du traitement des requêtes au
      système d'exploitation. Elle est activée par défaut dans le démon httpd
      d'Apache, mais peut nécessiter une reconfiguration de votre noyau.</li>

      <li>Optimisez la directive <code class="directive"><a href="../mod/mpm_common.html#maxrequestworkers">MaxRequestWorkers</a></code> de façon à définir le nombre
      maximum de connexions simultanées au dessus duquel les ressources
      s'épuisent. Voir aussi la <a href="perf-tuning.html">documentation sur l'optimisation des
      performances</a>.</li>

      <li>L'utilisation d'un <a href="../mpm.html">module mpm</a> threadé
      vous permet de traiter d'avantage de connexions simultanées, ce qui
      minimise l'effet des attaques DoS. Dans le futur, le module mpm
      <code class="module"><a href="../mod/event.html">event</a></code> utilisera un traitement asynchrone afin de ne pas
      dédier un thread à chaque connexion. De par la
      nature de la bibliothèque OpenSSL, le module mpm <code class="module"><a href="../mod/event.html">event</a></code> est actuellement incompatible
      avec le module <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> ainsi que d'autres filtres
      en entrée. Dans ces cas, son comportement se ramène à celui
      du module mpm <code class="module"><a href="../mod/worker.html">worker</a></code>.</li>

      <li>Il existe de nombreux modules tiers qui peuvent restreindre les
      comportements de certains clients et ainsi minimiser les problèmes de
      DoS.</li>

<h2><a name="serverroot" id="serverroot">Permissions sur les répertoires de la racine du serveur</a></h2>

    

    <p>Typiquement, Apache est démarré par l'utilisateur root, puis il devient
    la propriété de l'utilisateur défini par la directive <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code> afin de répondre aux demandes. Comme
    pour toutes les commandes exécutées par root, vous devez vous assurer
    qu'elle n'est pas modifiable par les utilisateurs autres que root. Les
    fichiers eux-mêmes, mais aussi les répertoires ainsi que leurs parents ne
    doivent être modifiables que par root. Par exemple, si vous avez choisi de
    placer la racine du serveur dans <code>/usr/local/apache</code>, il est conseillé de
    créer le répertoire en tant que root, avec des commandes du style :</p>

    <div class="example"><p><code>
      mkdir /usr/local/apache <br />
      cd /usr/local/apache <br />
      mkdir bin conf logs <br />
      chown 0 . bin conf logs <br />
      chgrp 0 . bin conf logs <br />
      chmod 755 . bin conf logs
    </code></p></div>

    <p>Nous supposerons que <code>/</code>, <code>/usr</code> et
    <code>/usr/local</code> ne sont modifiables que par
    root. Quand vous installez l'exécutable <code class="program"><a href="../programs/httpd.html">httpd</a></code>, vous
    devez vous assurer qu'il possède des protections similaires :</p>

    <div class="example"><p><code>
      cp httpd /usr/local/apache/bin <br />
      chown 0 /usr/local/apache/bin/httpd <br />
      chgrp 0 /usr/local/apache/bin/httpd <br />
      chmod 511 /usr/local/apache/bin/httpd
    </code></p></div>

    <p>Vous pouvez créer un sous-répertoire htdocs modifiable par d'autres
    utilisateurs -- car root ne crée ni exécute aucun fichier dans ce
    sous-répertoire.</p>

    <p>Si vous permettez à des utilisateurs non root de modifier des fichiers
    que root écrit ou exécute, vous exposez votre système à une compromission
    de l'utilisateur root. Par exemple, quelqu'un pourrait remplacer le binaire
    <code class="program"><a href="../programs/httpd.html">httpd</a></code> de façon à ce que la prochaine fois que vous le
    redémarrerez, il exécutera un code arbitraire. Si le répertoire des
    journaux a les droits en écriture (pour un utilisateur non root), quelqu'un
    pourrait remplacer un fichier journal par un lien symbolique vers un autre
    fichier système, et root pourrait alors écraser ce fichier avec des données
    arbitraires. Si les fichiers journaux eux-mêmes ont des droits en
    écriture (pour un utilisateur non root), quelqu'un pourrait
    modifier les journaux eux-mêmes avec des données fausses.</p>

<div class="section">
<h2><a name="ssi" id="ssi">Inclusions côté serveur</a></h2>

    

    <p>Les inclusions côté serveur (Server Side Includes - SSI) exposent
    l'administrateur du serveur à de nombreux risques potentiels en matière de
    sécurité.</p>

    <p>Le premier risque est l'augmentation de la charge du serveur. Tous les
    fichiers où SSI est activé doivent être analysés par Apache, qu'ils
    contiennent des directives SSI ou non. L'augmentation de la charge induite
    est minime, mais peut devenir significative dans le contexte d'un
    serveur partagé.</p>

    <p>Les fichiers SSI présentent les mêmes risques que les scripts CGI en
    général. Les fichiers où SSI est activé peuvent exécuter tout script CGI
    ou autre programme à l'aide de la commande <code>"exec cmd"</code> avec les permissions
    des utilisateur et groupe sous lesquels Apache s'exécute, comme défini
    dans <code>httpd.conf</code>.</p>

    <p>Des méthodes existent pour améliorer la sécurité des fichiers SSI, tout
    en tirant parti des bénéfices qu'ils apportent.</p>

    <p>Pour limiter les dommages qu'un fichier SSI agressif pourrait causer,
    l'administrateur du serveur peut activer<a href="../suexec.html">suexec</a>
    comme décrit dans la section <a href="#cgi">Les CGI en général</a>.</p>

    <p>L'activation des SSI pour des fichiers possédant des extensions
    <code>.html</code> ou
    <code>.htm</code> peut s'avérer dangereux. Ceci est particulièrement vrai dans un
    environnement de serveur partagé ou étant le siège d'un traffic élevé. Les
    fichiers où SSI est activé doivent posséder une extension spécifique, telle
    que la conventionnelle <code>.shtml</code>. Ceci permet de limiter la charge du serveur
    à un niveau minimum et de simplifier la gestion des risques.</p>

    <p>Une autre solution consiste à interdire l'exécution de scripts et
    programmes à partir de pages SSI. Pour ce faire, remplacez
    <code>Includes</code> par <code>IncludesNOEXEC</code> dans la directive
    <code class="directive"><a href="../mod/core.html#options">Options</a></code>. Notez que les utilisateurs
    pourront encore utiliser <code>&lt;--#include virtual="..." --&gt;</code> pour exécuter
    des scripts CGI si ces scripts sont situés dans des répertoires spécifiés
    par une directive
    <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>.</p>

<h2><a name="cgi" id="cgi">Les CGI en général</a></h2>

    

    <p>Tout d'abord, vous devez toujours garder à l'esprit que vous devez
    faire confiance aux développeurs de scripts ou programmes CGI ainsi qu'à
    vos compétences pour déceler les trous de sécurité potentiels dans les
    CGI, que ceux-ci soient délibérés ou accidentels. Les scripts CGI peuvent
    essentiellement exécuter des commandes arbitraires sur votre système avec
    les droits de l'utilisateur du serveur web, et peuvent par conséquent être
    extrèmement dangereux s'ils ne sont pas vérifiés avec soin.</p>

    <p>Tous les scripts CGI s'exécutent sous le même utilisateur, il peuvent
    donc entrer en conflit (accidentellement ou délibérément) avec d'autres
    scripts. Par exemple, l'utilisateur A hait l'utilisateur B, il écrit donc
    un script qui efface la base de données CGI de l'utilisateur B. Vous pouvez
    utiliser le programme <a href="../suexec.html">suEXEC</a> pour faire en
    sorte que les scripts s'exécutent sous des utilisateurs différents. Ce
    programme est inclus dans la distribution d'Apache depuis la version 1.2
    et est appelé à partir de certaines portions de code du serveur Apache. Une
    autre méthode plus connue est l'utilisation de
    <a href="http://cgiwrap.sourceforge.net/">CGIWrap</a>.</p>

<h2><a name="nsaliasedcgi" id="nsaliasedcgi">CGI sans alias de script</a></h2>

    

    <p>Vous ne devez permettre aux utilisateurs d'exécuter des scripts CGI

    <ul>
      <li>Vous faites confiance à vos utilisateurs pour ne pas écrire de
      scripts qui vont délibérément ou accidentellement exposer votre
      système à une attaque.</li>
      <li>Vous estimez que le niveau de sécurité dans les autres parties de
      votre site est si faible qu'un trou de sécurité de plus ou de moins

<h2><a name="saliasedcgi" id="saliasedcgi">CGI avec alias de script</a></h2>

    

    <p>Le confinement des CGI dans des répertoires spécifiques permet à
    l'administrateur de contrôler ce que l'on met dans ces répertoires. Ceci
    est bien entendu mieux sécurisé que les CGI sans alias de script, mais
    seulement à condition que les utilisateurs avec les droits en écriture sur
    les répertoires soient dignes de confiance, et que l'administrateur ait la
    volonté de tester chaque programme ou script CGI à la recherche d'éventuels
    trous de sécurité.</p>

    <p>La plupart des sites choisissent cette approche au détriment des CGI
    sans alias de script.</p>

  Les options de scripting intégrées qui s'exécutent en tant que partie du

  <code>mod_tcl</code>, et <code>mod_python</code>,
  s'exécutent sous le même utilisateur que le serveur (voir la directive
  <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code>), et par conséquent,
  les scripts que ces moteurs exécutent peuvent accéder aux mêmes ressources
  que le serveur. Certains moteurs de scripting peuvent proposer des
  restrictions, mais pour plus de sûreté, il vaut mieux partir du principe
  que ce n'est pas le cas.</p>

<h2><a name="systemsettings" id="systemsettings">Protection de la configuration du système</a></h2>

    

    <p>Pour contrôler étroitement votre serveur, vous pouvez interdire
    l'utilisation des fichiers <code>.htaccess</code> qui permettent de
    passer outre les fonctionnalités de sécurité que vous avez configurées.
    Voici un moyen pour y parvenir :</p>

    <p>Ajoutez dans le fichier de configuration du serveur</p>

    <pre class="prettyprint lang-config">&lt;Directory "/"&gt;
    AllowOverride None
&lt;/Directory&gt;</pre>


    <p>Ceci interdit l'utilisation des fichiers <code>.htaccess</code> dans
    tous les répertoires, sauf ceux pour lesquels c'est explicitement
    autorisé.</p>

    <p>Notez que c'est la configuration par défaut depuis Apache 2.3.9.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="protectserverfiles" id="protectserverfiles">Protection par défaut des fichiers du serveur</a></h2>

    

    <p>Le concept d'accès par défaut est un aspect d'Apache qui est parfois mal
    compris. C'est à dire que, à moins que vous ne changiez explicitement ce
    comportement, si le serveur trouve son chemin vers un fichier en suivant
    les règles normales de correspondance URL - fichier, il peut le retourner
    aux clients.</p>

    <p>Considérons l'exemple suivant :</p>

    <div class="example"><p><code>
      # cd /; ln -s / public_html <br />
      puis accès à <code>http://localhost/~root/</code>
    </code></p></div>

    <p>Ceci permettrait aux clients de parcourir l'ensemble du système de
    fichiers. Pour l'éviter, ajoutez le bloc suivant à la configuration
    de votre serveur :</p>

    <pre class="prettyprint lang-config">&lt;Directory "/"&gt;
    Require all denied
&lt;/Directory&gt;</pre>


    <p>ceci va interdire l'accès par défaut à tous les fichiers du système de
    fichiers. Vous devrez ensuite ajouter les blocs
    <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> appropriés correspondant
    aux répertoires auxquels vous voulez autorisez l'accès. Par exemple,</p>

    <pre class="prettyprint lang-config">&lt;Directory "/usr/users/*/public_html"&gt;
    Require all granted
&lt;/Directory&gt;
&lt;Directory "/usr/local/httpd"&gt;
    Require all granted
&lt;/Directory&gt;</pre>


    <p>Portez une attention particulière aux interactions entre les directives
    <code class="directive"><a href="../mod/core.html#location">Location</a></code> et
    <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> ; par exemple, si une
    directive <code>&lt;Directory ""/&gt;</code> interdit un accès, une
    directive <code>&lt;Location "/"&gt;</code> pourra passer outre.</p>

    <p>De même, soyez méfiant en jouant avec la directive
    <code class="directive"><a href="../mod/mod_userdir.html#userdir">UserDir</a></code> ; la positionner à
    <code>"./"</code> aurait le même effet, pour root, que le premier exemple plus haut.
    Nous vous conseillons
    fortement d'inclure la ligne suivante dans le fichier de configuration de
    votre serveur :</p>

    <pre class="prettyprint lang-config">UserDir disabled root</pre>

<h2><a name="watchyourlogs" id="watchyourlogs">Surveillez vos journaux</a></h2>

    

    <p>Pour vous tenir informé de ce qui se passe réellement dans votre
    serveur, vous devez consulter vos
    <a href="../logs.html">fichiers journaux</a>. Même si les fichiers journaux
    ne consignent que des évènements qui se sont déjà produits, ils vous
    informeront sur la nature des attaques qui sont lancées contre le serveur
    et vous permettront de vérifier si le niveau de sécurité nécessaire est
    atteint.</p>

    <p>Quelques exemples :</p>

    <div class="example"><p><code>
      grep -c "/jsp/source.jsp?/jsp/ /jsp/source.jsp??" access_log <br />
      grep "client denied" error_log | tail -n 10
    </code></p></div>

    <p>Le premier exemple listera les attaques essayant d'exploiter la
    <a href="http://online.securityfocus.com/bid/4876/info/">vulnérabilité
    d'Apache Tomcat pouvant provoquer la divulgation d'informations par des
    requêtes Source.JSP mal formées</a>, le second donnera la liste des dix
    dernières interdictions client ; par exemple :</p>

    <div class="example"><p><code>
      [Thu Jul 11 17:18:39 2002] [error] [client foo.example.com] client denied
      by server configuration: /usr/local/apache/htdocs/.htpasswd
    </code></p></div>

    <p>Comme vous le voyez, les fichiers journaux ne consignent que ce qui
    s'est déjà produit ; ainsi, si le client a pu accéder au fichier
    <code>.htpasswd</code>, vous devriez avoir quelque chose du style :</p>

    <div class="example"><p><code>
      foo.example.com - - [12/Jul/2002:01:59:13 +0200] "GET /.htpasswd HTTP/1.1"
    </code></p></div>

    <p>dans votre <a href="../logs.html#accesslog">journal des accès</a> ; ce
    qui signifie que vous avez probablement mis en commentaire ce qui suit dans
    le fichier de configuration de votre serveur :</p>

    <pre class="prettyprint lang-config">&lt;Files ".ht*"&gt;
    Require all denied
&lt;/Files&gt;</pre>

<h2><a name="merging" id="merging">Fusion des sections de configuration</a></h2>

    

    <p>La fusion des sections de configuration est complexe et dépend

    fusionnées.</p>

    <p>Concernant les modules qui n'implémentent aucune logique de
    fusion, comme <code class="module"><a href="../mod/mod_access_compat.html">mod_access_compat</a></code>, le
    comportement des sections suivantes est tributaire de la présence

<h2><a name="basic" id="basic">Authentification de base</a></h2>

    <p>Voici les cinq formats de mots de passe qu'Apache reconnaît
    pour l'authentification de base. Notez que tous les formats ne sont
    pas supportés par toutes les plates-formes :</p>

    <dl>
         
       <dt>bcrypt</dt>
       <dd>"$2y$" + the result of the crypt_blowfish algorithm. Dérivé
       de l'algorythme de chiffrement crypt_blowfish. Voir le fichier
       source APR <a href="http://svn.apache.org/viewvc/apr/apr/trunk/crypto/crypt_blowfish.c?view=markup">crypt_blowfish.c</a>
       pour plus de détails à propos de cet algorithme.</dd>

       <dt>MD5</dt>
       <dd>"$apr1$" + le résultat d'un algorithme spécifique à Apache
       utilisant un condensé MD5 réitéré (1000 fois) de combinaisons
       variées du mot de passe et d'une source d'entropie sur 32 bits.
       Voir le fichier source APR <a href="http://svn.apache.org/viewvc/apr/apr/trunk/crypto/apr_md5.c?view=markup">apr_md5.c</a>
       pour les détails de l'algorithme.</dd>
    

    <dt>SHA1</dt>
       <dd>"{SHA}" + un condensé SHA-1 du mot de passe codé en
       Base64. Non sûr.</dd>

    <dt>CRYPT</dt>
       <dd>Unix seulement. Utilise la fonction Unix traditionnelle
       <code>crypt(3)</code> avec une source d'entropie sur 32 bits
       (seuls 12 bits sont utilisés), et seulement les 8 premiers
       caractères du mot de passe. Non sûr.</dd>

    <dt>PLAIN TEXT (autrement dit <em>non chiffré</em>)</dt>
      <dd>Windows &amp; Netware seulement. Non sûr.</dd>
    </dl>
    <h3>Générer des mots de passe avec htpasswd</h3>

      <div class="example"><h3>bcrypt</h3><p><code>
      $ htpasswd -nbB monNom monMot-de-passe<br />
      monNom:$2y$05$c4WoMPo3SXsafkva.HHa6uXQZWr7oboPiC2bT/r7q1BB8I2s0BRqC
      </code></p></div>    

      <div class="example"><h3>MD5</h3><p><code>
      $ htpasswd -nbm monNom monMot-de-passe<br />
      monNom:$apr1$r31.....$HqJZimcKQFAMYayBlzkrA/
      </code></p></div>

      <div class="example"><h3>SHA1</h3><p><code>
      $ htpasswd -nbs monNom monMot-de-passe<br />
      monNom:{SHA}VBPuJHI7uixaa6LQGWx4s+5GKNE=
      </code></p></div>

      <div class="example"><h3>CRYPT</h3><p><code>
      $ htpasswd -nbd monNom monMot-de-passe<br />
      monNom:rqXexS6ZhobKA
      </code></p></div>

    

    <h3>Générer des mots de passe CRYPT and MD5 avec le programme
      OpenSSL en ligne de commande</h3>
      

      <p>OpenSSL connaît l'algorithme MD5 spécifique à Apache.</p>

      <div class="example"><h3>MD5</h3><p><code>
      $ openssl passwd -apr1 monMot-de-passe<br />
      $apr1$qHDFfhPC$nITSVHgYbDAK1Y0acGRnY0
      </code></p></div>

      <div class="example"><h3>CRYPT</h3><p><code>
      openssl passwd -crypt monMot-de-passe<br />
      qQ5vTYO3c8dsU
      </code></p></div>
    

    <h3>Valider des mots de passe CRYPT and MD5 avec le programme
      OpenSSL en ligne de commande</h3>
      
      <p>La source d'entropie pour un mot de passe CRYPT est constituée
      des deux premiers caractères (convertis en valeur binaire). Pour
      valider <code>monMot-de-passe</code> par rapport à
      <code>rqXexS6ZhobKA</code></p>

      <div class="example"><h3>CRYPT</h3><p><code>
      $ openssl passwd -crypt -salt rq monMot-de-passe<br />
      Warning: truncating password to 8 characters<br />
      rqXexS6ZhobKA
      </code></p></div>

      <p>Notez que spécifier <code>monMot-d</code> au lieu de
      <code>monMot-de-passe</code> produira le même résultat car seuls
      les 8 premiers caractères des mots de passe CRYPT sont pris en
      compte.</p>

      <p>La source d'entropie pour un mot de passe MD5 se situe entre
      <code>$apr1$</code> et le caractère <code>$</code> suivant (sous
      la forme d'une valeur binaire codée en Base64 - au maximum 8
      caractères). Pour valider <code>monMot-de-passe</code> par rapport
      à <code>$apr1$r31.....$HqJZimcKQFAMYayBlzkrA/</code></p>

      <div class="example"><h3>MD5</h3><p><code>
      $ openssl passwd -apr1 -salt r31..... monMot-de-passe<br />
      $apr1$r31.....$HqJZimcKQFAMYayBlzkrA/
      </code></p></div>
    

    <h3>Champs mot de passe de base de données pour
    mod_dbd</h3>
      <p>La variante SHA1 constitue probablement le format le mieux
      approprié pour l'authentification DBD. Comme les fonctions SHA1 et
      Base64 sont en général disponibles, d'autres logiciels peuvent
      renseigner une base de données avec des mots de passe chiffrés
      utilisables par l'authentification basique d'Apache.</p>

      <p>Pour créer des mots de passe au format SHA1 pour
      l'authentification de base d'Apache dans divers langages :</p>

      <div class="example"><h3>PHP</h3><p><code>
      '{SHA}' . base64_encode(sha1($password, TRUE))
      </code></p></div>

      <div class="example"><h3>Java</h3><p><code>
      "{SHA}" + new sun.misc.BASE64Encoder().encode(java.security.MessageDigest.getInstance("SHA1").digest(password.getBytes()))
      </code></p></div>

      <div class="example"><h3>ColdFusion</h3><p><code>
      "{SHA}" &amp; ToBase64(BinaryDecode(Hash(password, "SHA1"), "Hex"))
      </code></p></div>

      <div class="example"><h3>Ruby</h3><p><code>
      require 'digest/sha1'<br />
      require 'base64'<br />
      '{SHA}' + Base64.encode64(Digest::SHA1.digest(password))
      </code></p></div>

      <div class="example"><h3>C ou C++</h3><p><code>
      Utilisez la fonction APR : apr_sha1_base64
      </code></p></div>

      <div class="example"><h3>Python</h3><p><code>
      import base64<br />
      import hashlib<br />
      "{SHA}" + format(base64.b64encode(hashlib.sha1(password).digest()))
      </code></p></div>

      <div class="example"><h3>PostgreSQL (avec les fonctions contrib/pgcrypto
               installées)</h3><p><code>
        
        '{SHA}'||encode(digest(password,'sha1'),'base64')
      </code></p></div>
    

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="digest" id="digest">Authentification à base de condensés</a></h2>
    <p>Apache ne reconnaît qu'un format pour les mots de passe
    d'authentification à base de condensés - le condensé MD5 de la
    chaîne <code>utilisateur:domaine-de-protection:mot-de-passe</code>
    sous la forme d'une chaîne de 32 caractères au format hexadécimal.
    <code>domaine-de-protection</code> est l'identifiant du domaine de
    protection de l'autorisation passé en argument à la directive
    <code class="directive"><a href="../mod/mod_authn_core.html#authname">AuthName</a></code> dans

      logiciels peuvent renseigner une base de données avec des mots de

      condensés d'Apache.</p>

      <p>Pour créer des mots de passe pour l'authentification à base de
      condensés d'Apache dans divers langages :</p>

      <div class="example"><h3>PHP</h3><p><code>
      md5($user . ':' . $realm . ':' .$password)

      <div class="example"><h3>Java</h3><p><code>

        s = "0" + s;
      </span>
      // La chaîne s contient le mot de passe chiffré
      </code></p></div>

      LCase(Hash( (user &amp; ":" &amp; realm &amp; ":" &amp; password) , "MD5"))
      </code></p></div>

      <div class="example"><h3>Ruby</h3><p><code>
      require 'digest/md5'<br />

    <p>Apache 2.x, esneklik, taşınabilirlik ve başarım arasında bir denge
      sağlamak üzere tasarlanmış genel amaçlı bir HTTP sunucusudur. Başka
      sunucularla kıyaslama denemelerinde öne geçmek üzere tasarlanmamış
      olsa da Apache 2.x gerçek yaşamda karşılaşılan pek çok durumda oldukça
      yüksek bir başarıma ulaşacak yetenektedir.</p>

    <p>Apache 1.3 ile karşılaştırıldığında 2.x sürümleri toplam veri hızını
      ve ölçeklenebilirliği arttırmak için pek çok en iyileme seçeneği
      içerir. Bu iyileştirmelerin pek çoğu zaten öntanımlı olarak etkin
      olmakla birlikte derleme ve kullanım sırasında başarımı önemli ölçüde
      etkileyebilen yapılandırma seçenekleri de mevcuttur. Bu belgede, bir
      Apache 2.x kurulumunda sunucu yöneticisinin sunucunun başarımını
      arttırmak amacıyla yapılandırma sırasında neler yapabileceğinden
      bahsedilmiştir. Bu yapılandırma seçeneklerinden bazıları, httpd’nin
      donanımın ve işletim sisteminin olanaklarından daha iyi
      yararlanabilmesini sağlarken bir kısmı da  daha hızlı bir sunum için
      yöneticinin işlevsellikten ödün verebilmesini olanaklı kılar.</p>

<h2><a name="hardware" id="hardware">Donanım ve İşletim Sistemi ile İlgili Konular</a></h2>

    

    <p>HTTP sunucusunun başarımını etkileyen en önemli donanım bellektir
      (RAM). Bir HTTP sunucusu asla takaslama yapmamalıdır. Çünkü takaslama,
      kullanıcının "yeterince hız" umduğu noktada sunumun gecikmesine sebep
      olur. Böyle bir durumda kullanıcılar yüklemeyi durdurup tekrar
      başlatma eğilimindedirler; sonuçta yük daha da artar. <code class="directive"><a href="../mod/mpm_common.html#maxrequestworkers">MaxRequestWorkers</a></code> yönergesinin değerini
      değiştirerek takaslamaya sebep olabilecek kadar çok çocuk süreç
      oluşturulmasını engelleyebilirsiniz ve böyle bir durumda bunu mutlaka
      yapmalısınız. Bunun için yapacağınız işlem basittir: <code>top</code>
      benzeri bir araç üzerinden çalışan süreçlerinizin bir listesini alıp
      Apache süreçlerinizin ortalama büyüklüğünü saptayıp, mevcut bellekten
      bir kısmını diğer süreçler için ayırdıktan sonra kalan miktarı bu
      değere bölerseniz yönergeye atayacağınız değeri bulmuş olursunuz.</p>

    <p>Donanımın diğer unsurları için kararı siz verin: Daha hızlı işlemci,
      daha hızlı ağ kartı, daha hızlı disk; daha hızlının ne kadar hızlı
      olacağını deneyimlerinize bağlı olarak tamamen sizin ihtiyaçlarınız
      belirler.</p>

    <p>İşletim sistemi seçimi büyük oranda yerel ilgi konusudur. Fakat yine
      de, genelde yararlılığı kanıtlanmış bazı kurallar bu seçimde size
      yardımcı olabilir:</p>

    <ul>
      <li>
        <p>Seçtiğiniz işletim sisteminin (çekirdeğin) en son kararlı
          sürümünü çalıştırın. Bir çok işletim sistemi, son yıllarda TCP
          yığıtları ve evre kütüphaneleri ile ilgili belirgin iyileştirmeler
          yapmışlar ve yapmaktadırlar.</p>
      </li>

      <li>
        <p>İşletim sisteminiz <code>sendfile</code>(2) sistem çağrısını
          destekliyorsa bunun etkinleştirilebildiği sürümün kurulu olması
          önemlidir. (Örneğin, Linux için bu, Linux 2.4 ve sonraki sürümler
          anlamına gelirken, Solaris için Solaris 8’den önceki sürümlerin
          yamanması gerektirdiği anlamına gelmektedir.)
          <code>sendfile</code> işlevinin desteklendiği sistemlerde Apache 2
          duruk içeriği daha hızlı teslim etmek ve işlemci kullanımını
          düşürmek amacıyla bu işlevselliği kullanacaktır.</p>

    <h3><a name="dns" id="dns"><code>HostnameLookups</code> ve DNS ile ilgili diğer konular</a></h3>

      

      <p>Apache 1.3 öncesinde, <code class="directive"><a href="../mod/core.html#hostnamelookups">HostnameLookups</a></code> yönergesinin öntanımlı değeri
        <code>On</code> idi. İstek yerine getirilmeden önce bir DNS sorgusu
        yapılmasını gerektirmesi sebebiyle bu ayarlama her istekte bir
        miktar gecikmeye sebep olurdu. Apache 1.3’ten itibaren yönergenin
        öntanımlı değeri <code>Off</code> yapılmıştır. Eğer günlük
        dosyalarınızda konak isimlerinin bulunmasını isterseniz, Apache ile
        birlikte gelen <code class="program"><a href="../programs/logresolve.html">logresolve</a></code> programını
        kullanabileceğiniz gibi günlük raporlarını çözümleyen Apache ile
        gelmeyen programlardan herhangi birini de kullanabilirsiniz.</p>

      <p>Günlük dosyaları üzerindeki bu işlemi sunucu makinesi dışında
        günlük dosyasının bir kopyası üzerinde yapmanızı öneririz. Aksi
        takdirde sunucunuzun başarımı önemli ölçüde etkilenebilir.</p>

      <p><code class="directive"><a href="../mod/mod_access_compat.html#allow">Allow</a></code> veya
        <code class="directive"><a href="../mod/mod_access_compat.html#deny">Deny</a></code>
        yönergelerinde IP adresi yerine bir konak veya alan ismi
        belirtirseniz, iki DNS sorguluk bir bedel ödersiniz (biri normal,
        diğeri IP taklidine karşı ters DNS sorgusu). Başarımı en iyilemek
        için bu yönergelerde mümkün olduğunca isim yerine IP adreslerini
        kullanınız.</p>

      <p><code class="directive"><a href="../mod/core.html#hostnamelookups">HostnameLookups</a></code>
        yönergelerinin <code>&lt;Location "/server-status"&gt;</code> gibi
        bölüm yönergelerinin içinde de yer alabileceğini unutmayın. Bu gibi
        durumlarda DNS sorguları sadece istek kuralla eşleştiği takdirde
        yapılacaktır. Aşağıdaki örnekte <code>.html</code> ve
        <code>.cgi</code> dosyalarına yapılan istekler hariç DNS sorguları
        iptal edilmektedir:</p>

      <pre class="prettyprint lang-config">HostnameLookups off
&lt;Files ~ "\.(html|cgi)$"&gt;
  HostnameLookups on
&lt;/Files&gt;</pre>


      <p>Yine de bazı CGI’lerin DNS isimlerine ihtiyacı olursa bu CGI’lerin
        bu ihtiyaçlarına yönelik olarak <code>gethostbyname</code> çağrıları
        yapabileceğini gözardı etmeyiniz.</p>

    

    <h3><a name="symlinks" id="symlinks"><code>FollowSymLinks</code> ve
        <code>SymLinksIfOwnerMatch</code></a></h3>

      

      <p>URL uzayınızda geçerli olmak üzere bir <code>Options
        FollowSymLinks</code> yoksa veya <code>Options
        SymLinksIfOwnerMatch</code> yönergeleri varsa, Apache her sembolik
        bağın üzerinde bazı sınamalar yapmak için ek bir sistem çağrısından
        başka istenen her dosya için de ayrı bir çağrı yapacaktır.</p>

      <pre class="prettyprint lang-config">DocumentRoot "/siteler/htdocs"
&lt;Directory /&gt;
  Options SymLinksIfOwnerMatch
&lt;/Directory&gt;</pre>


      <p>Bu durumda <code>/index.html</code> için bir istek yapıldığında
        Apache, <code>/siteler</code>, <code>/siteler/htdocs</code> ve<br />
        <code>/siteler/htdocs/index.html</code> üzerinde
        <code>lstat</code>(2) çağrıları yapacaktır. <code>lstat</code>
        sonuçları önbelleğe kaydedilmediğinden bu işlem her istekte
        yinelenecektir. Amacınız gerçekten sembolik bağları güvenlik
        açısından sınamaksa bunu şöyle yapabilirsiniz:</p>

      <pre class="prettyprint lang-config">DocumentRoot "/siteler/htdocs"
&lt;Directory "/"&gt;
  Options FollowSymLinks
&lt;/Directory&gt;

&lt;Directory "/siteler/htdocs"&gt;
  Options -FollowSymLinks +SymLinksIfOwnerMatch
&lt;/Directory&gt;</pre>


      <p>Böylece <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> altındaki
        dosyalar için fazladan bir çağrı yapılmasını engellemiş olursunuz.
        Eğer bazı bölümlerde <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> gibi yönergeler üzerinden belge kök
        dizininizin dışında kalan dosya yollarına sahipseniz benzer
        işlemleri onlar için de yapmalısınız. Sembolik bağ koruması yapmamak
        suretiyle başarımı arttırmak isterseniz, <code>FollowSymLinks</code>
        seçeneğini her yerde etkin kılın ve
        <code>SymLinksIfOwnerMatch</code> seçeneğini asla
        etkinleştirmeyin.</p>

    

    <h3><a name="htaccess" id="htaccess"><code>AllowOverride</code></a></h3>

      

      <p>Genellikle <code>.htaccess</code> dosyaları üzerinden yapıldığı
        gibi URL uzayınızda geçersizleştirmelere izin veriyorsanız, Apache
        her dosya bileşeni için bu <code>.htaccess</code> dosyalarını açmaya
        çalışacaktır.</p>

      <pre class="prettyprint lang-config">DocumentRoot "/siteler/htdocs"
&lt;Directory "/"&gt;
  AllowOverride all
&lt;/Directory&gt;</pre>


      <p>Bu durumda <code>/index.html</code> sayfasına yapılan bir istek için
        Apache, <code>/.htaccess</code>, <code>/siteler/.htaccess</code> ve
        <code>/siteler/htdocs/.htaccess</code> dosyalarını açmaya
        çalışacaktır. Çözüm <code>Options FollowSymLinks</code> durumunun
        benzeridir; başarımı arttırmak için dosya sisteminizin her yerinde
        <code>AllowOverride None</code> olsun.</p>

    

    <h3><a name="negotiation" id="negotiation">Dil Uzlaşımı</a></h3>

      

      <p>Başarımı son kırıntısına kadar arttırmak istiyorsanız, mümkünse
        içerik dili uzlaşımı da yapmayın. Dil uzlaşımından yararlanmak
        isterken büyük başarım kayıplarına uğrayabilirsiniz. Böyle bir
        durumda sunucunun başarımını arttırmanın tek bir yolu vardır. </p>

      <pre class="prettyprint lang-config">DirectoryIndex index</pre>


      <p>Yukarıdaki gibi bir dosya ismi kalıbı kullanmak yerine, aşağıdaki
        gibi seçenekleri tam bir liste halinde belirtin:</p>

      <pre class="prettyprint lang-config">DirectoryIndex index.cgi index.pl index.shtml index.html</pre>


      <p>Buradaki sıralama öncelik sırasını belirler; yani,
        öncelikli olmasını istediğiniz seçeneği listenin başına
        yazmalısınız.</p>

      <p>İstenen dosya için <code>MultiViews</code> kullanarak dizini
        taratmak yerine, gerekli bilgiyi tek bir dosyadan okutmak suretiyle
        başarımı arttırabilirsiniz. Bu amaçla türeşlem
        (<code>type-map</code>) dosyaları kullanmanız yeterli olacaktır.</p>

      <p>Sitenizde içerik dili uzlaşımına gerek varsa, bunu <code>Options
        MultiViews</code> yönergesi üzerinden değil, türeşlem dosyaları
        kullanarak yapmayı deneyin. İçerik dili uzlaşımı ve türeşlem
        dosyalarının oluşturulması hakkında daha ayrıntılı bilgi edinmek
        için <a href="../content-negotiation.html">İçerik Uzlaşımı</a>
        belgesine bakınız.</p>

    

    <h3>Bellek Eşlemleri</h3>

      

      <p>Apache’nin SSI sayfalarında olduğu gibi teslim edilecek dosyanın
        içeriğine bakma gereği duyduğu durumlarda, eğer işletim sistemi
        <code>mmap</code>(2) ve benzerlerini destekliyorsa çekirdek normal
        olarak dosyayı belleğe kopyalayacaktır.</p>

      <p>Bazı platformlarda bu belleğe eşleme işlemi başarımı arttırsa da
        başarımın veya httpd kararlılığının zora girdiği durumlar
        olabilmektedir:</p>

      <ul>
        <li>
          <p>Bazı işletim sistemlerinde işlemci sayısı artışına bağlı
            olarak, <code>mmap</code> işlevi <code>read</code>(2) kadar iyi
            ölçeklenmemiştir. Örneğin, çok işlemcili Solaris sunucularda
            <code>mmap</code> iptal edildiği takdirde içeriği sunucu
            tarafından işlenen dosyalar üzerinde bazen daha hızlı işlem
            yapılabilmektedir.</p>
        </li>

        <li>
          <p>Belleğe kopyalanacak dosya NFS üzerinden bağlanan bir dosya
            sistemindeyse ve dosya başka bir NFS istemcisi makine tarafından
            silinmiş veya dosyanın boyutu değiştirilmişse sunucunuz dosyaya
            tekrar erişmeye çalıştığında bir hata alabilecektir.</p>
        </li>
      </ul>

      <p>Böyle durumların olasılık dahilinde olduğu kurulumlarda içeriği

    <h3><code>sendfile</code></h3>

      

      <p>Apache’nin duruk dosyalarda olduğu gibi teslim edilecek dosyanın
        içeriğine bakmadığı durumlarda, eğer işletim sistemi
        <code>sendfile</code>(2) desteğine sahipse çekirdek normal olarak bu
        desteği kullanacaktır.</p>

      <p>Bazı platformlarda <code>sendfile</code> kullanımı, okuma ve yazma
        işlemlerinin ayrı ayrı yapılmamasını sağlasa da
        <code>sendfile</code> kullanımının httpd kararlılığını bozduğu bazı
        durumlar sözkonusudur:</p>

      <ul>
        <li>
          <p>Bazı platformlar derleme sisteminin saptayamadığı bozuk bir
            <code>sendfile</code> desteğine sahip olabilir. Özellikle
            derleme işleminin başka bir platformda yapılıp
            <code>sendfile</code> desteği bozuk bir makineye kurulum
            yapıldığı durumlarda bu desteğin bozuk olduğu
            saptanamayacaktır.</p>
        </li>
        <li>
          <p>Çekirdek, NFS üzerinden erişilen ağ dosyalarını kendi önbelleği
            üzerinden gerektiği gibi sunamayabilir.</p>
        </li>
      </ul>

      <p>Böyle durumların olasılık dahilinde olduğu kurulumlarda içeriğin

        yapılandırmanıza <code>EnableSendfile off</code> satırını ekleyiniz.

    <h3><a name="process" id="process">Süreç Oluşturma</a></h3>

      

      <p>Apache 1.3 öncesinde <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>, <code class="directive"><a href="../mod/prefork.html#maxspareservers">MaxSpareServers</a></code> ve <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> ayarları, başka sunucularla kıyaslama
        denemelerinde olağanüstü kötü sonuçlar alınmasına sebep olmaktaydı.
        Özellikle uygulanan yükü karşılamaya yetecek sayıda çocuk süreç
        oluşturulması aşamasında Apache’nin elde ettiği ivme bunlardan
        biriydi. Başlangıçta <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> yönergesiyle belli sayıda süreç
        oluşturulduktan sonra her saniyede bir tane olmak üzere <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code> sayıda çocuk süreç
        oluşturulmaktaydı. Örneğin, aynı anda 100 isteğe yanıt vermek için
        <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code>
        yönergesinin öntanımlı değeri olarak başta <code>5</code> süreç
        oluşturulduğundan kalan süreçler için 95 saniye geçmesi gerekirdi.
        Sık sık yeniden başlatılmadıklarından dolayı gerçek hayatta
        sunucuların başına gelen de buydu. Başka sunucularla kıyaslama
        denemelerinde ise işlem sadece on dakika sürmekte ve içler acısı
        sonuçlar alınmaktaydı.</p>

      <p>Saniyede bir kuralı, sunucunun yeni çocukları oluşturması sırasında
        sistemin aşırı meşgul duruma düşmemesi için alınmış bir önlemdi.
        Makine çocuk süreç oluşturmakla meşgul edildiği sürece isteklere
        yanıt veremeyecektir. Böylesi bir durum Apache’nin başarımını
        kötüleştirmekten başka işe yaramayacaktır. Apache 1.3’te saniyede
        bir kuralı biraz esnetildi. Yeni gerçeklenimde artık bir süreç
        oluşturduktan bir saniye sonra iki süreç, bir saniye sonra dört
        süreç oluşturulmakta ve işlem, saniyede 32 çocuk süreç oluşturulur
        duruma gelene kadar böyle ivmelenmektedir. Çocuk süreç oluşturma
        işlemi <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>
        değerine ulaşılınca durmaktadır.</p>

      <p>Bu, <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>,
        <code class="directive"><a href="../mod/prefork.html#maxspareservers">MaxSpareServers</a></code> ve
        <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> ayarlarıyla
        oynamayı neredeyse gereksiz kılacak kadar iyi sonuçlar verecek gibi
        görünmektedir. Saniyede 4 çocuktan fazlası oluşturulmaya
        başlandığında hata günlüğüne bazı iletiler düşmeye başlar. Bu
        iletilerin sayısı çok artarsa bu ayarlarla oynama vakti gelmiş
        demektir. Bunun için <code class="module"><a href="../mod/mod_status.html">mod_status</a></code> çıktısını bir
        kılavuz olarak kullanabilirsiniz.</p>

      <p>Süreç oluşturmayla ilgili olarak süreç ölümü <code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code> değeri ile
        sağlanır. Bu değer öntanımlı olarak <code>0</code> olup, çocuk süreç
        başına istek sayısının sınırsız olduğu anlamına gelir. Eğer
        yapılandırmanızda bu değeri <code>30</code> gibi çok düşük bir
        değere ayarlarsanız bunu hemen kaldırmak zorunda kalabilirsiniz.
        Sunucunuzu SunOS veya Solaris’in eski bir sürümü üzerinde
        çalıştırıyorsanız bellek kaçaklarına sebep olmamak için bu değeri
        <code>10000</code> ile sınırlayınız.</p>

      <p>Kalıcı bağlantı özelliğini kullanıyorsanız, çocuk süreçler zaten
        açık bağlantılardan istek beklemekte olacaklardır. <code class="directive"><a href="../mod/core.html#keepalivetimeout">KeepAliveTimeout</a></code> yönergesinin öntanımlı
        değeri <code>5</code> saniye olup bu etkiyi en aza indirmeye yönelik
        süredir. Burada ağ band genişliği ile sunucu kaynaklarının kullanımı
        arasında bir seçim yapmak söz konusudur. Hiçbir şey umurunuzda
        değilse <a href="http://www.hpl.hp.com/techreports/Compaq-DEC/WRL-95-4.html">
        çoğu ayrıcalığın yitirilmesi pahasına</a> bu değeri rahatça
        <code>60</code> saniyenin üzerine çıkarabilirsiniz.</p>

<h2><a name="compiletime" id="compiletime">Derleme Sırasında Yapılandırma ile İlgili Konular</a></h2>
    

    <h3>MPM Seçimi</h3>
      

      <p>Apache 2.x, <a href="../mpm.html">Çok Süreçlilik Modülleri</a>
        (MPM) adı verilen eklemlenebilir çok görevlilik modellerini
        destekler. Apache’yi derlerken bu MPM’lerden birini seçmeniz
        gerekir. MPM’lerden bazıları platformlara özeldir:
        <code class="module"><a href="../mod/mpm_netware.html">mpm_netware</a></code>, <code class="module"><a href="../mod/mpmt_os2.html">mpmt_os2</a></code> ve
        <code class="module"><a href="../mod/mpm_winnt.html">mpm_winnt</a></code>. Unix
        benzeri sistemler için ise seçebileceğiniz modül sayısı birden
        fazladır. MPM seçiminin httpd’nin hızında ve ölçeklenebilirliğinde
        bazı etkileri olabilir:</p>

      <ul>

        <li><code class="module"><a href="../mod/worker.html">worker</a></code> modülü her biri çok evreli çok sayıda
          çocuk süreç kullanımını destekler. Her evre aynı anda tek bir
          bağlantıya hizmet sunar. Aynı hizmeti daha az bellek harcayarak
          vermesi nedeniyle yüksek trafiğe sahip sunucularda
          <code class="module"><a href="../mod/prefork.html">prefork</a></code> modülüne göre daha iyi bir seçimdir.</li>

        <li><code class="module"><a href="../mod/event.html">event</a></code> modülü <code class="module"><a href="../mod/worker.html">worker</a></code> modülü gibi
          çok evreli bir modüldür, fakat aunı anda dahafazla isteğe yanıt
          verecek şekilde tasarlanmıştır. Bunu, evreleri destekleyen bazı
          işlemleri yapmamak suretiyle yeni isteklerle çalışacak ana evreleri
          serbestleştirerek sağlar.</li>

        <li><code class="module"><a href="../mod/prefork.html">prefork</a></code> modülü her biri tek bir evreye sahip
          çok sayıda çocuk süreç kullanımını destekler. Her süreç aynı anda
          tek bir bağlantıya hizmet sunar. Çoğu sistemde daha hızlı olması
          nedeniyle <code class="module"><a href="../mod/worker.html">worker</a></code> modülüne göre daha iyi bir seçim
          olarak görünürse de bunu daha fazla bellek kullanarak sağlar.
          <code class="module"><a href="../mod/prefork.html">prefork</a></code> modülünün evresiz tasarımının
          <code class="module"><a href="../mod/worker.html">worker</a></code> modülüne göre bazı yararlı tarafları
          vardır: Çok evreli sistemlerde güvenilir olmayan üçüncü parti
          modülleri kullanabilir ve evrelerde hata ayıklamanın yetersiz
          kaldığı platformlarda hatalarını ayıklamak daha kolaydır.</li>

      </ul>

      <p>Bu modüller ve diğerleri hakkında daha ayrıntılı bilgi edinmek için
        <a href="../mpm.html">Çok Süreçlilik Modülleri</a> belgesine
        bakınız.</p>

    

    <h3><a name="modules" id="modules">Modüller</a></h3>

        

        <p>Bellek kullanımı başarım konusunda önemli olduğundan gerçekte
        kullanmadığınız modülleri elemeye çalışmalısınız. Modülleri birer <a href="../dso.html">DSO</a> olarak derlediyseniz <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> yönergesinin bulunduğu satırı
        açıklama haline getirmeniz modülden kurtulmanız için yeterli
        olacaktır. Modülleri bu şekilde kaldırarak onların yokluğunda
        sitenizin hala işlevlerini yerine getirdiğini görme şansına da
        kavuşmuş olursunuz.</p>

        <p>Ancak, eğer modülleri Apache çalıştırılabilirinin içine
        gömmüşseniz istenmeyen modülleri kaldırmak için Apache'yi yeniden
        derlemeniz gerekir.</p>

        <p>Bu noktada bir soru akla gelebilir: Hangi modüller gerekli,
        hangileri değil? Bu sorunun yanıtı şüphesiz siteden siteye değişir.
        Ancak, olmazsa olmaz moüller olarak <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code>,
        <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> ve <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>
        modüllerini sayabiliriz. Bunlardan <code>mod_log_config</code>
        olmadan da bir sitenin çalışabileceğinden hareketle bu modülün
        varlığı isteğe bağlı olsa da bu modülü kaldırmanızı önermiyoruz.</p>

    

    <h3>Atomik İşlemler</h3>

      

      <p>Worker MPM'nin en son geliştirme sürümleri ve
      <code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code> gibi bazı modüller APR'nin atomik API'sini
      kullanırlar. Bu API, düşük ayarlı evre eşzamanlamasında atomik
      işlemler yapar.</p>

      <p>Öntanımlı olarak, APR bu işlemleri hedef işletim sistemi/işlemci
      platformunda kullanılabilecek en verimli mekanizmayı kullanarak
      gerçekleştirir. Günümüz işlemcilerinin çoğu, örneğin, bir atomik
      karşılaştırma ve takas (CAS) işlemini donanımda gerçekleştirmektedir.
      Bazı platformlarda APR'nin atomik işlemler için öntanımlı olarak daha
      yavaş olan mutekslere dayalı gerçeklenimi kullanmasının sebebi eski
      işlemcilerde bu tür makine kodlarının yokluğudur. Apache'yi bu tür
      platformalarda günümüz işlemcileriyde çalıştırmayı düşünüyorsanız
      Apache'yi derlemek için yapılandırırken en hızlı atomik işlemin
      seçilebilmesi için <code>--enable-nonportable-atomics</code>
      seçeneğini kullanın:</p>

      <div class="example"><p><code>
        ./buildconf<br />
        ./configure --with-mpm=worker --enable-nonportable-atomics=yes
      </code></p></div>

      <p><code>--enable-nonportable-atomics</code> seçeneği şu platformlar
      için uygundur:</p>

      <ul>

        <li>SPARC üzerinde Solaris<br />
            APR öntanımlı olarak, SPARC/Solaris üzerinde mutekslere dayalı
            atomik işlemleri kullanır. Ancak,
            <code>--enable-nonportable-atomics</code> yapılandırmasını
            kullanırsanız, donanım üzerinde hızlı karşılaştırma ve takas
            için uygun SPARC v8plus kodunu kullanacak şekilde kod üretilir.
            Apache'yi bu seçenekle yapılandırırsanız atomik işlemler daha
            verimli olacak fakat derlenen Apache çalıştırılabiliri sadece
            UltraSPARC kırmığı üzerinde çalışacaktır.
        </li>

        <li>x86 üzerinde Linux<br />
            APR öntanımlı olarak, Linux üzerinde mutekslere dayalı atomik
            işlemleri kullanır. Ancak,
            <code>--enable-nonportable-atomics</code> yapılandırmasını
            kullanırsanız, donanım üzerinde hızlı karşılaştırma ve takas
            için uygun 486 kodunu kullanacak şekilde kod üretilir. Apache'yi
            bu seçenekle yapılandırırsanız atomik işlemler daha verimli
            olacak fakat derlenen Apache çalıştırılabiliri (386 üzerinde
            değil) sadece 486 ve sonrası kırmıklarda çalışacaktır.
        </li>

      </ul>

    

    <h3><code>mod_status</code> ve <code>ExtendedStatus On</code>
      </h3>

      

      <p><code class="module"><a href="../mod/mod_status.html">mod_status</a></code> modülünü derlemiş ve Apache'yi
      yapılandırır ve çalıştırırken <code>ExtendedStatus On</code> satırını
      da kullanmışsanız Apache her istek üzerinde
      <code>gettimeofday(2)</code> (veya işletim sistemine bağlı olarak
      <code>time(2)</code>) çağrısından başka (1.3 öncesinde) fazladan
      defalarca  <code>time(2)</code> çağrıları yapacaktır. Bu çağrılarla
      durum raporununun zamanlama bilgilerini içermesi sağlanır. Başarımı
      arttırmak için <code>ExtendedStatus off</code> yapın (zaten öntanımlı
      böyledir).</p>

    

    <h3><code>accept</code> dizgilemesi ve çok soketli işlem</h3>

      

    <div class="warning"><h3>Uyarı:</h3>
      <p>Bu bölüm, Apache HTTP sunucusunun 2.x sürümlerinde yapılan
      değişikliklere göre tamamen güncellenmemiştir. Bazı bilgiler hala
      geçerliyse de lütfen dikkatli kullanınız.</p>
    </div>

      <p>Burada Unix soket arayüzü gerçeklenirken ihmal edilen bir durumdan
      bahsedeceğiz. HTTP sunucunuzun çok sayıda adresten çok sayıda portu
      dinlemek için çok sayıda <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> yönergesi kullanmakta olduğunu varsayalım. Her
      soketi çalıştığını görmek için denerken Apache bağlantı için
      <code>select(2)</code> kullanacaktır. <code>select(2)</code> çağrısı
      bu soketin üzerinde <em>sıfır</em> veya <em>en azından bir</em>
      bağlantının beklemekte olduğu anlamına gelir. Apache'nin modeli çok
      sayıda çocuk süreç içerir ve boşta olanların tümünde aynı anda yeni
      bağlantılar denenebilir. Gerçekte çalışan kod bu olmasa da meramımızı
      anlatmak için kodun şöyle bir şey olduğunu varsayabiliriz:</p>

      <pre class="prettyprint lang-c">        for (;;) {
          for (;;) {
            fd_set accept_fds;

            FD_ZERO (&amp;accept_fds);
            for (i = first_socket; i &lt;= last_socket; ++i) {
              FD_SET (i, &amp;accept_fds);
            }
            rc = select (last_socket+1, &amp;accept_fds, NULL, NULL, NULL);
            if (rc &lt; 1) continue;
            new_connection = -1;
            for (i = first_socket; i &lt;= last_socket; ++i) {
              if (FD_ISSET (i, &amp;accept_fds)) {
                new_connection = accept (i, NULL, NULL);
                if (new_connection != -1) break;
              }
            }
            if (new_connection != -1) break;
          }
          process_the(new_connection);
        }</pre>


      <p>Bu özet gerçeklenim bir takım açlık sorunlarına sebep olur. Bu
      döngünün çalışması sırasında aynı anda çok sayıda çocuk süreç yeniden
      çağrılır ve istekler arasında kalan çoğu çocuk da <code>select</code>
      ile engellenir. Engellenen tüm bu çocuklar soketlerden herhangi biri
      üzerinde tek bir istek göründüğünde <code>select</code> tarafından
      uyandırılıp işleme sokulmak üzere döndürülürler. (Uyandırılan çocuk
      sayısı işletim sistemine ve zamanlama ayarlarına göre değişiklik
      gösterir,) Bunların hepsi döngüye katılıp bağlantı kabul etmeye
      (<code>accept</code>) çalışırlar. Fakat içlerinden yalnız biri
      (sadece bir bağlantı isteğinin mevcut olduğu varsayımıyla) bunu
      başarabilir. Kalanının bağlantı kabul etmesi (<code>accept</code>)
      <em>engellenir</em>. Bu durum, bu çocukları istekleri başka başka soketlerden
      değil mecburen tek bir soketten kabul etmeye kilitler ve bu soket
      üzerinde yeni bir istek belirip uyandırılana kadar bu durumda
      kalırlar. Bu açlık sorunu ilk olarak <a href="http://bugs.apache.org/index/full/467">PR#467</a> sayılı raporla
      belgelenmiştir. Bu sorunun en az iki çözümü vardır.</p>

      <p>Çözümün biri engellenmeyen soket kullanımıdır. Bu durumda
      <code>accept</code> çocukları engellemeyecek ve yapılan bir
      bağlantının ardından diğer çocuklar durumları değişmeksizin bağlantı
      beklemeye devam edeceklerdir. Fakat bu durum işlemci zamanının boşa
      harcanmasına sebep olur.  Seçilmiş (<code>select</code>) boşta on
      çocuğun olduğunu ve bir bağlantı geldiğini varsayalım. Kalan dokuz
      çocuk işine devam edip bağlantı kabul etmeyi (<code>accept</code>)
      deneyecek, başarızsız olacak, dönecek başa, tekrar seçilecek
      (<code>select</code>) ve böyle hiçbir iş yapmadan dönüp duracaktır. Bu
      arada hizmet sunmakta olanlar da işlerini bitirdikten sonra bu
      döngüdeki yerlerini alacaklardır. Aynı kutunun içinde boşta bir sürü
      işlemciniz (çok işlemcili sistemler) yoksa bu çözüm pek verimli
      olmayacaktır.</p>

      <p>Diğer çözüm ise Apache tarafından kullanılan çözüm olup, girdiyi
      bir iç döngüde sıraya sokmaktır. Döngü aşağıda örneklenmiştir (farklar
      vurgulanmıştır):</p>

      <pre class="prettyprint lang-c">        for (;;) {
          <strong>accept_mutex_on ();</strong>
          for (;;) {
            fd_set accept_fds;

            FD_ZERO (&amp;accept_fds);
            for (i = first_socket; i &lt;= last_socket; ++i) {
              FD_SET (i, &amp;accept_fds);
            }
            rc = select (last_socket+1, &amp;accept_fds, NULL, NULL, NULL);
            if (rc &lt; 1) continue;
            new_connection = -1;
            for (i = first_socket; i &lt;= last_socket; ++i) {
              if (FD_ISSET (i, &amp;accept_fds)) {
                new_connection = accept (i, NULL, NULL);
                if (new_connection != -1) break;
              }
            }
            if (new_connection != -1) break;
          }
          <strong>accept_mutex_off ();</strong>
          process the new_connection;
        }</pre>


      <p><code>accept_mutex_on</code> ve <code>accept_mutex_off</code> <a id="serialize" name="serialize">işlevleri</a> bir karşılıklı red
      semoforu oluştururlar. Mutekse aynı anda sadece bir çocuk sahip
      olabilir. Bu muteksleri gerçeklemek için çeşitli seçenekler vardır.
      Seçim, <code>src/conf.h</code> (1.3 öncesi) veya
      <code>src/include/ap_config.h</code> (1.3 ve sonrası) dosyasında
      tanımlanmıştır. Bazı mimariler bir kilitleme seçeneğine sahip
      değildir. Böyle mimarilerde çok sayıda <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> yönergesi kullanmak güvenilir
      olmayacaktır.</p>

      <p><code class="directive"><a href="../mod/core.html#mutex">Mutex</a></code> yönergesi,
      <code>mpm-accept</code> muteks gerçeklenimini çalışma anında değiştirmek
      için kullanılabilir. Farklı muteks gerçeklenimleri ile ilgili hususlar
      bu yönergede belgelenmiştir.</p>

      <p>Başka bir çözüm daha vardır ancak döngü kısmen dizgilenmeyeceğinden
      (yani belli sayıda sürece izin verilemeyeceğinden) asla
      gerçeklenmemiştir. Bu sadece, aynı anda çok sayıda çocuk sürecin
      çalışabileceği ve dolayısıyla band genişliğinin tüm yönleriyle
      kullanılabileceği çok işlemcili sistemlerde ilginç olabilirdi. Bu
      gelecekte incelenmeye değer bir konu olmakla beraber çok sayıda HTTP
      sunucusunun aynı anda aynı amaca hizmet edecek şekilde çalışması
      standart olarak pek mümkün görülmediğinden bu olasılık çok
      düşüktür.</p>

      <p>En yüksek başarımı elde etmek için ideal olanı sunucuları
      çalıştırırken çok sayıda <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> yönergesi kullanmamaktır. Fakat siz yine de
      okumaya devam edin.</p>

    

    <h3><code>accept</code> dizgilemesi - tek soket</h3>

      

      <p>Çok soketli sunucular için yukarıda açıklananlar iyi güzel de tek
      soketli sunucularda durum ne? Kuramsal olarak, bunların hiçbiriyle bir
      sorunları olmaması gerekir. Çünkü yeni bir bağlantı gelene kadar tüm
      çocuklar <code>accept(2)</code> ile engellenirler dolayısıyla hiçbir
      açlık sorununun ortaya çıkmaması gerekir. Uygulamada ise son
      kullanıcıdan gizli olarak, yukarıda engellenmeyen çocuklar çözümünde
      bahsedilenle hemen hemen aynı "boşa dönüp durma" davranışı mevcuttur.
      Çoğu TCP yığıtı bu yolu gerçeklemiştir. Çekirdek, yeni bir bağlantı
      ortaya çıktığında <code>accept</code> ile engellenen tüm süreçleri
      uyandırır. Bu süreçlerden bağlantıyı alan kullanıcı bölgesine geçerken
      çekirdek içinde döngüde olan diğerleri de yeni bağlantı keşfedilene
      kadar uykularına geri dönerler. Bu çekirdek içi döngü, kullanıcı
      bölgesindeki kodlara görünür değildir ama bu olmadıkları anlamına
      gelmez. Bu durum, çok soketli engellenmeyen çocuklar çözümündeki boşa
      döngünün sebep olduğu gereksiz işlemci yükü sorununu içinde
      barındırır.</p>

      <p>Bununla birlikte, tek soketli durumda bile bundan daha verimli bir
      davranış sergileyen bir çok mimari bulduk. Bu aslında hemen hemen her
      durumda öntanımlı olarak böyledir. Linux altında yapılan üstünkörü
      denemelerde (128MB bellekli çift Pentium pro 166 işlemcili makinede
      Linux 2.0.30) tek sokette dizgilemenin dizgilenmemiş duruma göre
      saniyede %3 daha az istekle sonuçlandığı gösterilmiştir. Fakat
      dizgilenmemiş tek soket durumunda her istekte 100ms'lik ek bir gecikme
      olduğu görülmüştür. Bu gecikmenin sebebi muhtemelen uzun mesafeli
      hatlar olup sadece yerel ağlarda söz konusudur. Tek soketli
      dizgilemeyi geçersiz kılmak için
      <code>SINGLE_LISTEN_UNSERIALIZED_ACCEPT</code> tanımlarsanız tek
      soketli sunucularda artık dizgileme yapılmayacaktır.</p>

    

    <h3>Kapatmayı zamana yaymak</h3>

      

      <p><a href="http://www.ics.uci.edu/pub/ietf/http/draft-ietf-http-connection-00.txt">draft-ietf-http-connection-00.txt</a> taslağının 8. bölümünde
      bahsedildiği gibi, bir HTTP sunucusunun protokolü <strong>güvenilir
      şekilde</strong> gerçeklemesi için her iki yöndeki iletişimi
      birbirinden bağımsız olarak (iki yönlü bir TCP bağlantısının her
      yarısını diğerinden bağımsız olarak) kapatması gerekir.</p>

      <p>Bu özellik Apache'ye eklendiğinde Unix'in çeşitli sürümlerinde
      uzgörüsüzlükten dolayı bir takım geçici telaş sorunlarına sebep oldu.
      TCP belirtimi <code>FIN_WAIT_2</code> durumunda bir zaman aşımından
      bahsetmez ama yasaklamaz da. Zaman aşımı olmayan sistemlerde, Apache
      1.2 çoğu soketin sonsuza kadar <code>FIN_WAIT_2</code> durumunda
      takılıp kalmasına sebep olur. Çoğu durumda, satıcıdan sağlanan en son
      TCP/IP yamalarını uygulanarak bu önlenebilir. Satıcının hiçbir yeni
      yama dağıtmadığı durumlarda (örneğin, SunOS4 -- bir kaynak lisansı ile
      insanlar bunu kendileri yamayabilirse de) bu özelliği devre dışı
      bırakmaya karar verdik.</p>

      <p>Bunun üstesinden gelmenin iki yolu vardır. Bunlardan biri
      <code>SO_LINGER</code> soket seçeneğidir. Bu işin kaderi buymuş gibi
      görünürse de çoğu TCP/IP yığıtında bu gerektiği gibi
      gerçeklenmemiştir. Bu yığıtlar üzerinde, bu yöntemin, doğru bir
      gerçeklenimle bile (örneğin, Linux 2.0.31) sonraki çözümden daha
      pahalı olduğu ortaya çıkmıştır.</p>

      <p>Çoğunlukla, Apache bunu (<code>http_main.c</code> içindeki)
      <code>lingering_close</code> adında bir işlevle gerçekler. Bu işlev
      kabaca şöyle görünür:</p>

      <pre class="prettyprint lang-c">        void lingering_close (int s)
        {
          char junk_buffer[2048];

          /* shutdown the sending side */
          shutdown (s, 1);

          signal (SIGALRM, lingering_death);
          alarm (30);

          for (;;) {
            select (s for reading, 2 second timeout);
            if (error) break;
            if (s is ready for reading) {
              if (read (s, junk_buffer, sizeof (junk_buffer)) &lt;= 0) {
                break;
              }
              /* just toss away whatever is here */
            }
          }

          close (s);
        }</pre>


      <p>Bağlantı sonunda bu doğal olarak biraz daha masrafa yol açar, fakat
      güvenilir bir gerçeklenim için bu gereklidir. HTTP/1.1'in daha yaygın
      kullanılmaya başlanması ve tüm bağlantıların kalıcı hale gelmesiyle bu
      gerçeklenim daha fazla istek üzerinden kendi masrafını
      karşılayacaktır. Ateşle oynamak ve bu özelliği devre dışı bırakmak
      isterseniz <code>NO_LINGCLOSE</code>'u tanımlayabilirsiniz, fakat bu
      asla önerilmez. Özellikle, HTTP/1.1'den itibaren boruhatlı kalıcı
      bağlantıların <code>lingering_close</code> kullanmaya başlaması mutlak
      bir gerekliliktir (ve <a href="http://www.w3.org/Protocols/HTTP/Performance/Pipeline.html">
      boruhatlı bağlantıların daha hızlı</a> olması nedeniyle bu
      bağlantıları desteklemek isteyebilirsiniz).</p>

    

    <h3>Çetele Dosyası</h3>

      

      <p>Apache'nin ana ve alt süreçleri birbirleriyle çetele denen birşey
      üzerinden haberleşirler. Bunun en mükemmel şekilde paylaşımlı bellekte
      gerçeklenmesi gerekir. Eriştiğimiz veya portlarını ayrıntılı olarak
      belirttiğimiz işletim sistemleri için bu, genellikle paylaşımlı bellek
      kullanılarak gerçeklenir. Geri kalanlar, öntanımlı olarak bunu bir
      disk dosyası kullanarak gerçekler. Bir disk dosyaı yavaş olmanın yanı
      sıra güvenilir de değildir (ve daha az özelliğe sahiptir). Mimarinizin
      <code>src/main/conf.h</code> dosyasını inceleyin ve
      <code>USE_MMAP_SCOREBOARD</code> veya
      <code>USE_SHMGET_SCOREBOARD</code>'a bakın. Bu ikisinden birinin (ve
      yanı sıra sırasıyla <code>HAVE_MMAP</code> veya
      <code>HAVE_SHMGET</code>'in) tanımlanmış olması, sağlanan paylaşımlı
      bellek kodunu etkinleştirir. Eğer sisteminiz diğer türdeki paylaşımlı
      belleğe sahipse, <code>src/main/http_main.c</code> dosyasını açıp,
      Apache'de bu belleği kullanması gereken kanca işlevleri ekleyin (Bize
      de bir yama yollayın, lütfen).</p>

      <div class="note">Tarihsel bilgi: Apache'nin Linux uyarlaması, Apache'nin 1.2
      sürümüne kadar paylaşımlı belleği kullanmaya başlamamıştı. Bu kusur,
      Apache'nin Linux üzerindeki erken dönem sürümlerinin davranışlarının
      zayıf ve güvenilmez olmasına yol açmıştı.</div>

    

    <h3>DYNAMIC_MODULE_LIMIT</h3>

      

      <p>Devingen olarak yüklenen modülleri kullanmamak niyetindeyseniz
      (burayı okuyan ve sunucunuzun başarımını son kırıntısına kadar
      arttırmakla ilgilenen biriyseniz bunu düşünmezsiniz), sunucunuzu
      derlerken seçenekler arasına <code>-DDYNAMIC_MODULE_LIMIT=0</code>
      seçeneğini de ekleyin. Bu suretle, sadece, devingen olarak yüklenen
      modüller için ayrılacak belleği kazanmış olacaksınız.</p>

    

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="trace" id="trace">Ek: Bir çağrı izlemesinin ayrıntılı çözümlemesi</a></h2>

    

    <p>Burada, Solaris 8 üzerinde worker MPM'li Apache 2.0.38'in bir sistem
    çağrısı izlenmektedir. Bu izleme şu komutla elde edilmiştir:</p>

    <div class="example"><p><code>
      truss -l -p <var>httpd_çocuk_pidi</var>.
    </code></p></div>

    <p><code>-l</code> seçeneği, truss'a hafif bir sürecin yaptığı her
    sistem çağrısını (hafif süreç -- HS -- Solaris'in bir çekirdek seviyesi
    evreleme biçimi) günlüğe yazmasını söyler.</p>

    <p>Diğer sistemlerin sistem çağrılarını izleyen farklı araçları vardır
    (<code>strace</code>, <code>ktrace</code>, <code>par</code> gibi).
    Bunlar da benzer çıktılar üretirler.</p>

    <p>Bu izleme sırasında, bir istemci httpd'den 10 KB'lık duruk bir dosya
    talebinde bulunmuştur. Duruk olmayan veya içerik uzlaşımlı isteklerin
    izleme kayıtları vahşice (bazı durumlarda epey çirkince) farklı
    görünür.</p>

    <div class="example"><p><code>
      /67:    accept(3, 0x00200BEC, 0x00200C0C, 1) (uykuda...)<br />
      /67:    accept(3, 0x00200BEC, 0x00200C0C, 1)            = 9
    </code></p></div>

    <p>Bu izlemede, dinleyen evre HS #67 içinde çalışmaktadır.</p>

    <div class="note"><code>accept(2)</code> dizgelemesinin olmayışına dikkat edin.
    Özellikle bu platformda worker MPM, çok sayıda portu dinlemedikçe,
    öntanımlı olarak dizgeleştirilmemiş bir accept çağrısı kullanır.</div>

    <div class="example"><p><code>
      /65:    lwp_park(0x00000000, 0)                         = 0<br />
      /67:    lwp_unpark(65, 1)                               = 0
    </code></p></div>

    <p>Bağlantının kabul edilmesiyle, dinleyici evre isteği yerine getirmek
    üzere bir worker evresini uyandırır. Bu izlemede, isteği yerine getiren
    worker evresi  HS #65'e aittir.</p>

    <div class="example"><p><code>
      /65:    getsockname(9, 0x00200BA4, 0x00200BC4, 1)       = 0
    </code></p></div>

    <p>Sanal konakların gerçeklenimi sırasında, Apache'nin, bağlantıları
    kabul etmek için kullanılan yerel soket adreslerini bilmesi gerekir.
    Çoğu durumda bu çağrıyı bertaraf etmek mümkündür (hiç sanal konağın
    olmadığı veya <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>
    yönergelerinin mutlak adreslerle kullanıldığı durumlarda). Fakat bu en
    iyilemeleri yapmak için henüz bir çaba harcanmamıştır.</p>

    <div class="example"><p><code>
      /65:    brk(0x002170E8)                                 = 0<br />
      /65:    brk(0x002190E8)                                 = 0
    </code></p></div>

    <p><code>brk(2)</code> çağrıları devingen bellekten bellek ayırır. httpd
    çoğu isteği yerine getirirken özel bellek ayırıcılar
    (<code>apr_pool</code> ve <code>apr_bucket_alloc</code>) kullandığından
    bunlar bir sistem çağrısı izlemesinde nadiren görünür. Bu izlemede,
    httpd henüz yeni başlatıldığından, özel bellek ayırıcıları oluşturmak
    için ham bellek bloklarını ayırmak amacıyla <code>malloc(3)</code>
    çağrıları yapması gerekir.</p>

    <div class="example"><p><code>
/65:    fcntl(9, F_GETFL, 0x00000000)                   = 2<br />
/65:    fstat64(9, 0xFAF7B818)                          = 0<br />
/65:    getsockopt(9, 65535, 8192, 0xFAF7B918, 0xFAF7B910, 2190656) = 0<br />
/65:    fstat64(9, 0xFAF7B818)                          = 0<br />
/65:    getsockopt(9, 65535, 8192, 0xFAF7B918, 0xFAF7B914, 2190656) = 0<br />
/65:    setsockopt(9, 65535, 8192, 0xFAF7B918, 4, 2190656) = 0<br />
/65:    fcntl(9, F_SETFL, 0x00000082)                   = 0
    </code></p></div>

    <p>Ardından, worker evresi istemciye (dosya tanıtıcısı 9) engellenmeyen
    kipte bir bağlantı açar. <code>setsockopt(2)</code>
    ve <code>getsockopt(2)</code> çağrıları, Solaris libc'sinin soketler
    üzerindeki <code>fcntl(2)</code> çağrısı yanında birer yan etkiden
    ibarettirler.</p>

    <div class="example"><p><code>
      /65:    read(9, " G E T   / 1 0 k . h t m".., 8000)     = 97
    </code></p></div>

    <p>Worker evresi istemciden isteği okur.</p>

    <div class="example"><p><code>
/65:    stat("/var/httpd/apache/httpd-8999/htdocs/10k.html", 0xFAF7B978) = 0<br />
/65:    open("/var/httpd/apache/httpd-8999/htdocs/10k.html", O_RDONLY) = 10
    </code></p></div>

    <p>Bu httpd  <code>Options FollowSymLinks</code> ve <code>AllowOverride
    None</code> ile yapılandırılmıştır. Bu bakımdan, ne istenen dosya ile
    sonuçlanan yol üzerindeki her dizinde <code>lstat(2)</code> çağrısına ne
    de <code>.htaccess</code> dosyalarına bakılmasına gerek vardır.
    <code>stat(2)</code> çağrısı basitçe dosya için şunları doğrulamak
    amacıyla yapılır: 1) dosya mevcuttur ve 2) bir dizin değil normal bir
    dosyadır.</p>

    <div class="example"><p><code>
      /65:    sendfilev(0, 9, 0x00200F90, 2, 0xFAF7B53C)      = 10269
    </code></p></div>

    <p>Bu örnekte, httpd, istenen dosyayı ve HTTP yanıt başlığını tek bir
    <code>sendfilev(2)</code> sistem çağrısı ile  göndermektedir. Dosya
    gönderim işleminin anlamı sistemden sisteme değişiklik gösterir. Bazı
    sistemlerde, <code>sendfile(2)</code> çağrısından önce başlıkları
    göndermek için  <code>write(2)</code> veya <code>writev(2)</code>
    çağrısı yapmak gerekir.</p>

    <div class="example"><p><code>
      /65:    write(4, " 1 2 7 . 0 . 0 . 1   -  ".., 78)      = 78
    </code></p></div>

    <p>Bu <code>write(2)</code> çağrısı isteği erişim günlüğüne kaydeder. Bu
    izlemede eksik olan tek şey, <code>time(2)</code> çağrısıdır. Apache
    1.3'ün aksine, Apache 2.x zamana bakmak için
    <code>gettimeofday(3)</code> çağırısını kullanır. Linux ve Solaris gibi
    bazı işletim sistemleri, <code>gettimeofday</code> işlevinin, sıradan
    bir sistem çağrısından daha fazla götürüsü olmayan en iyilenmiş bir
    gerçeklenimine sahiptir.</p>

    <div class="example"><p><code>
      /65:    shutdown(9, 1, 1)                               = 0<br />
      /65:    poll(0xFAF7B980, 1, 2000)                       = 1<br />
      /65:    read(9, 0xFAF7BC20, 512)                        = 0<br />
      /65:    close(9)                                        = 0
    </code></p></div>

    <p>Burada worker evresi bağlantıyı zamana yaymaktadır.</p>

    <div class="example"><p><code>
      /65:    close(10)                                       = 0<br />
      /65:    lwp_park(0x00000000, 0)         (uykuda...)
    </code></p></div>

    <p>Son olarak, worker evresi teslim edilen dosyayı kapattıktan sonra
    dinleyici evre tarafından başka bir bağlantı atanıncaya kadar beklemeye
    alınır.</p>

    <div class="example"><p><code>
      /67:    accept(3, 0x001FEB74, 0x001FEB94, 1) (uykuda...)
    </code></p></div>

    <p>Bu arada, dinleyici evre bağlantıyı bir worker evresine atar atamaz
    başka bir bağlantıyı beklemeye başlar (Mevcut tüm evreler meşgulse
    dinleyici evreyi baskılayan worker MPM'nin akış denetim şemasına konu
    olur). Bu izlemede görünmüyor olsa da sonraki <code>accept(2)</code>
    çağrısı, yeni bağlantı kabul eden worker evresine paralel olarak
    yapılabilir (aşırı yük durumlarında normal olarak, bu yapılır).</p>

<h2><a name="basic" id="basic">Basic Authentication</a></h2>

    <p>There are five formats that Apache recognizes for basic-authentication
    passwords. Note that not all formats work on every platform:</p>

    <dl>
       <dt>bcrypt</dt>
       <dd>"$2y$" + the result of the crypt_blowfish algorithm.
       See the APR source file
       <a href="http://svn.apache.org/viewvc/apr/apr/trunk/crypto/crypt_blowfish.c?view=markup">crypt_blowfish.c</a>
       for the details of the algorithm.</dd>

       <dt>MD5</dt>
       <dd>"$apr1$" + the result of an Apache-specific algorithm using an
       iterated (1,000 times) MD5 digest of various combinations of a
       random 32-bit salt and the password. See the APR source file
       <a href="http://svn.apache.org/viewvc/apr/apr/trunk/crypto/apr_md5.c?view=markup">apr_md5.c</a>
       for the details of the algorithm.</dd>

       <dt>SHA1</dt>
       <dd>"{SHA}" + Base64-encoded SHA-1 digest of the password. Insecure.</dd>

       <dt>CRYPT</dt>
       <dd>Unix only. Uses the traditional Unix <code>crypt(3)</code> function
       with a randomly-generated 32-bit salt (only 12 bits used) and the first 8
       characters of the password. Insecure.</dd>

       <dt>PLAIN TEXT (i.e. <em>unencrypted</em>)</dt>
       <dd>Windows &amp; Netware only. Insecure.</dd>
    </dl>

    <h3>Generating values with htpasswd</h3>

      <div class="example"><h3>bcrypt</h3><p><code>
      $ htpasswd -nbB myName myPassword<br />
      myName:$2y$05$c4WoMPo3SXsafkva.HHa6uXQZWr7oboPiC2bT/r7q1BB8I2s0BRqC
      </code></p></div>

      <div class="example"><h3>MD5</h3><p><code>
      $ htpasswd -nbm myName myPassword<br />
      myName:$apr1$r31.....$HqJZimcKQFAMYayBlzkrA/
      </code></p></div>

      <div class="example"><h3>SHA1</h3><p><code>
      $ htpasswd -nbs myName myPassword<br />
      myName:{SHA}VBPuJHI7uixaa6LQGWx4s+5GKNE=
      </code></p></div>

      <div class="example"><h3>CRYPT</h3><p><code>
      $ htpasswd -nbd myName myPassword<br />
      myName:rqXexS6ZhobKA
      </code></p></div>

    

    <h3>Generating CRYPT and MD5 values with the OpenSSL
             command-line program</h3>
      

      <p>OpenSSL knows the Apache-specific MD5 algorithm.</p>

      <div class="example"><h3>MD5</h3><p><code>
      $ openssl passwd -apr1 myPassword<br />
      $apr1$qHDFfhPC$nITSVHgYbDAK1Y0acGRnY0
      </code></p></div>

      <div class="example"><h3>CRYPT</h3><p><code>
      openssl passwd -crypt myPassword<br />
      qQ5vTYO3c8dsU
      </code></p></div>
    

    <h3>Validating CRYPT or MD5 passwords with the OpenSSL command
             line program</h3>
      
      <p>The salt for a CRYPT password is the first two characters (converted to
      a binary value). To validate <code>myPassword</code> against
      <code>rqXexS6ZhobKA</code></p>

      <div class="example"><h3>CRYPT</h3><p><code>
      $ openssl passwd -crypt -salt rq myPassword<br />
      Warning: truncating password to 8 characters<br />
      rqXexS6ZhobKA
      </code></p></div>

      <p>Note that using <code>myPasswo</code> instead of
      <code>myPassword</code> will produce the same result because only the
      first 8 characters of CRYPT passwords are considered.</p>

      <p>The salt for an MD5 password is between <code>$apr1$</code> and the
      following <code>$</code> (as a Base64-encoded binary value - max 8 chars).
      To validate <code>myPassword</code> against
      <code>$apr1$r31.....$HqJZimcKQFAMYayBlzkrA/</code></p>

      <div class="example"><h3>MD5</h3><p><code>
      $ openssl passwd -apr1 -salt r31..... myPassword<br />
      $apr1$r31.....$HqJZimcKQFAMYayBlzkrA/
      </code></p></div>
    

    <h3>Database password fields for mod_dbd</h3>
      <p>The SHA1 variant is probably the most useful format for DBD
      authentication. Since the SHA1 and Base64 functions are commonly
      available, other software can populate a database with encrypted passwords
      that are usable by Apache basic authentication.</p>

      <p>To create Apache SHA1-variant basic-authentication passwords in various
      languages:</p>

      <div class="example"><h3>PHP</h3><p><code>
      '{SHA}' . base64_encode(sha1($password, TRUE))
      </code></p></div>

      <div class="example"><h3>Java</h3><p><code>
      "{SHA}" + new sun.misc.BASE64Encoder().encode(java.security.MessageDigest.getInstance("SHA1").digest(password.getBytes()))
      </code></p></div>

      <div class="example"><h3>ColdFusion</h3><p><code>
      "{SHA}" &amp; ToBase64(BinaryDecode(Hash(password, "SHA1"), "Hex"))
      </code></p></div>

      <div class="example"><h3>Ruby</h3><p><code>
      require 'digest/sha1'<br />
      require 'base64'<br />
      '{SHA}' + Base64.encode64(Digest::SHA1.digest(password))
      </code></p></div>

      <div class="example"><h3>C or C++</h3><p><code>
      Use the APR function: apr_sha1_base64
      </code></p></div>

      <div class="example"><h3>Python</h3><p><code>
      import base64<br />
      import hashlib<br />
      "{SHA}" + format(base64.b64encode(hashlib.sha1(password).digest()))
      </code></p></div>

      <div class="example"><h3>PostgreSQL (with the contrib/pgcrypto functions
               installed)</h3><p><code>
        
        '{SHA}'||encode(digest(password,'sha1'),'base64')
      </code></p></div>
    

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="digest" id="digest">Digest Authentication</a></h2>
    <p>Apache recognizes one format for
    digest-authentication passwords - the MD5 hash of the string
    <code>user:realm:password</code> as a 32-character string of hexadecimal
    digits. <code>realm</code> is the Authorization Realm argument to the
    <code class="directive"><a href="../mod/mod_authn_core.html#authname">AuthName</a></code> directive in
    httpd.conf.</p>

    <h3>Database password fields for mod_dbd</h3>

      <p>Since the MD5 function is commonly available, other software can
      populate a database with encrypted passwords that are usable by Apache
      digest authentication.</p>

      <p>To create Apache digest-authentication passwords in various
      languages:</p>

      <div class="example"><h3>PHP</h3><p><code>
      md5($user . ':' . $realm . ':' .$password)
      </code></p></div>

      <div class="example"><h3>Java</h3><p><code>
      byte b[] = java.security.MessageDigest.getInstance("MD5").digest( (user + ":" + realm + ":" + password ).getBytes());<br />
      java.math.BigInteger bi = new java.math.BigInteger(1, b);<br />
      String s = bi.toString(16);<br />
      while (s.length() &lt; 32)<br />
      <span class="indent">
        s = "0" + s;
      </span>
      // String s is the encrypted password
      </code></p></div>

      <div class="example"><h3>ColdFusion</h3><p><code>
      LCase(Hash( (user &amp; ":" &amp; realm &amp; ":" &amp; password) , "MD5"))
      </code></p></div>

      <div class="example"><h3>Ruby</h3><p><code>
      require 'digest/md5'<br />
      Digest::MD5.hexdigest(user + ':' + realm + ':' + password)
      </code></p></div>

      <div class="example"><h3>PostgreSQL (with the contrib/pgcrypto functions installed)</h3><p><code>
        
        encode(digest( user || ':' || realm || ':' || password , 'md5'), 'hex')

      konularıyla oldukça ilgili bir geliştirici topluluğuna sahiptir. Fakat,
      bir yazılımın dağıtılmasının ardından küçük ya da büyük bazı sorunların
      keşfedilmesi kaçınılmazdır. Bu sebeple, yazılım güncellemelerinden
      haberdar olmak oldukça önem kazanır. HTTP sunucunuzu doğrudan
      Apache’den temin ediyorsanız yeni sürümler ve güvenlik güncellemeleri
      ile ilgili bilgileri tam zamanında alabilmek için <a href="http://httpd.apache.org/lists.html#http-announce">Apache
      HTTP Sunucusu Duyuru Listesi</a>ne mutlaka üye olmanızı öneririz.
      Apache yazılımının üçüncü parti dağıtımlarını yapanların da buna benzer
      hizmetleri vardır.</p>

    <p>Şüphesiz, bir HTTP sunucusu, sunucu kodunda bir sorun olmasa da
      tehlike altındadır. Eklenti kodları, CGI betikleri hatta işletim
      sisteminden kaynaklanan sorunlar nedeniyle bu ortaya çıkabilir. Bu
      bakımdan, sisteminizdeki tüm yazılımların sorunları ve güncellemeleri
      hakkında bilgi sahibi olmalısınız.</p>

<h2><a name="dos" id="dos">Hizmet Reddi (DoS) Saldırıları</a></h2>
    

    <p>Tüm ağ sunucuları, istemcilerin sistem kaynaklarından yararlanmalarını
      engellemeye çalışan hizmet reddi saldırılarına (HRS) maruz kalabilir.
      Bu tür saldırıları tamamen engellemek mümkün değildir, fakat
      yarattıkları sorunları azaltmak için bazı şeyler yapabilirsiniz.</p>

    <p>Çoğunlukla en etkili anti-HRS aracı bir güvenlik duvarı veya başka bir
      işletim sistemi yapılandırmasıdır. Örneğin, çoğu güvenlik duvarı
      herhangi bir IP adresinden aynı anda yapılan bağlantıların sayısına bir
      sınırlama getirmek üzere yapılandırılabilir. Böylece basit saldırılar
      engellenebilir. Ancak bunun dağıtık hizmet reddi saldırılarına (DHRS)
      karşı bir etkisi olmaz.</p>

    <p>Bunların yanında Apache HTTP Sunucusunun da sorunları azaltıcı
      tedbirler alınmasını sağlayacak bazı yapılandırmaları vardır:</p>

    <ul>
      <li><code class="directive"><a href="../mod/mod_reqtimeout.html#requestreadtimeout">RequestReadTimeout</a></code>
        yönergesi bir istemcinin isteği göndermek için harcadığı zamanı
        sınırlamayı sağlar.</li>

      <li>HRS’ye maruz kalması olası sitelerde <code class="directive"><a href="../mod/core.html#timeout">TimeOut</a></code> yönergesinin değeri düşürülmelidir. Birkaç
        saniye gibi mümkün olduğunca düşük bir ayar uygun olabilir. Ancak
        <code class="directive"><a href="../mod/core.html#timeout">TimeOut</a></code> başka işlemlerde de
        kullanıldığından çok düşük değerler, örneğin, uzun süre çalışan CGI
        betiklerinde sorunlar çıkmasına sebep olabilir.</li>

      <li>HRS’ye maruz kalması olası sitelerde <code class="directive"><a href="../mod/core.html#keepalivetimeout">KeepAliveTimeout</a></code> yönergesinin değeri de düşürülebilir.
        Hatta bazı siteler başarımı arttırmak amacıyla <code class="directive"><a href="../mod/core.html#keepalive">KeepAlive</a></code> yönergesi üzerinden kalıcı
        bağlantıları tamamen kapatabilirler.</li>

      <li>Zaman aşımıyla ilgili yönergeler bakımından diğer modüller de
        araştırılmalıdır.</li>

      <li><code class="directive"><a href="../mod/core.html#limitrequestbody">LimitRequestBody</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestfields">LimitRequestFields</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestfieldsize">LimitRequestFieldSize</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestline">LimitRequestLine</a></code> ve
      <code class="directive"><a href="../mod/core.html#limitxmlrequestbody">LimitXMLRequestBody</a></code> yönergeleri,
        istemci girdileri ile tetiklenen özkaynak tüketimini sınırlamak için
        yapılandırılırken dikkatli olunmalıdır.</li>

      <li>İşletim sisteminiz desteklediği takdirde, işletim sisteminin isteği
        işleyen kısmını yüksüz bırakmak için <code class="directive"><a href="../mod/core.html#acceptfilter">AcceptFilter</a></code> yönergesinin etkin olmasını sağlamalısınız.
        Bu, Apache HTTP Sunucusunda zaten öntanımlı olarak etkindir.
        Yapacağınız şey işletim sistemi çekirdeğini buna göre yapılandırmak
        olacaktır.</li>

      <li>Sunucu tarafından özkaynakları tüketmeden aynı anda işlenebilecek
        bağlantıların sayısını sınırlamak için <code class="directive"><a href="../mod/mpm_common.html#maxrequestworkers">MaxRequestWorkers</a></code> yönergesini kullanın. Ayrıca, <a href="perf-tuning.html">başarım arttırma belgesine</a> de
        bakabilirsiniz.</li>

      <li>HRS’lerin etkilerini azaltmak için aynı andaki bağlantı sayısını
        arttırabilecek evreli <a href="../mpm.html">MPM</a>’lerden birini
        kullanmak iyi olabilir. Dahası, <code class="module"><a href="../mod/event.html">event</a></code> MPM’i
        her bağlantıya yeni bir evre atanmaması için eşzamansız işlem yapar.
        OpenSSL kütüphanesinin doğası nedeniyle
        <code class="module"><a href="../mod/event.html">event</a></code> MPM’i <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> ve diğer girdi
        süzgeçleri ile henüz uyumlu değildir. Bu durumlarda,
        <code class="module"><a href="../mod/worker.html">worker</a></code> MPM'inin davranışına geri döner.</li>

      <li>Belli istemci davranışlarını sınırlayacak ve HRS ile
        ilgili sorunları azaltmaya yardımcı olacak üçüncü parti modüller
        bulunabilir.</li>
    </ul>

<h2><a name="serverroot" id="serverroot"><code>ServerRoot</code> Dizinlerinin İzinleri</a></h2>
    

    <p>Normalde, Apache root kullanıcı tarafından başlatılır ve hizmetleri
      sunarken <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code> yönergesi
      tarafından tanımlanan kullanıcının aidiyetinde çalışır. Root tarafından
      çalıştırılan komutlarda olduğu gibi, root olmayan kullanıcıların
      yapacakları değişikliklerden korunmak konusunda da dikkatli
      olmalısınız. Dosyaların sadece root tarafından yazılabilir olmasını
      sağlamak yeterli değildir, bu dizinler ve üst dizinler için de
      yapılmalıdır. Örneğin, sunucu kök dizininin
      <code>/usr/local/apache</code> olmasına karar verdiyseniz, bu dizini
      root olarak şöyle oluşturmanız önerilir:</p>

    <div class="example"><p><code>
      mkdir /usr/local/apache <br />
      cd /usr/local/apache <br />
      mkdir bin conf logs <br />
      chown 0 . bin conf logs <br />
      chgrp 0 . bin conf logs <br />
      chmod 755 . bin conf logs
    </code></p></div>

    <p><code>/</code>, <code>/usr</code>, <code>/usr/local</code>
      dizinlerinde sadece root tarafından değişiklik yapılabileceği kabul
      edilir. <code class="program"><a href="../programs/httpd.html">httpd</a></code> çalıştırılabilirini kurarken de benzer
      bir önlemin alındığından emin olmalısınız:</p>

    <div class="example"><p><code>
      cp httpd /usr/local/apache/bin <br />
      chown 0 /usr/local/apache/bin/httpd <br />
      chgrp 0 /usr/local/apache/bin/httpd <br />
      chmod 511 /usr/local/apache/bin/httpd
    </code></p></div>

    <p>Diğer kullanıcıların değişiklik yapabileceği bir dizin olarak bir
      <code>htdocs</code> dizini oluşturabilirsiniz. Bu dizine root
      tarafından çalıştırılabilecek dosyalar konulmamalı ve burada root
      tarafından hiçbir dosya oluşturulmamalıdır.</p>

    <p>Diğer kullanıcılara root tarafından yazılabilen ve çalıştırılabilen
      dosyalarda değişiklik yapma hakkını tanırsanız, onlara root
      kullanıcısını ele geçirilebilme hakkını da tanımış olursunuz. Örneğin,
      biri <code class="program"><a href="../programs/httpd.html">httpd</a></code> çalıştırılabilirini zararlı bir programla
      değiştirebilir ve o programı tekrar çalıştırdığınız sırada program
      yapacağını yapmış olur. Günlükleri kaydettiğiniz dizin herkes
      tarafından yazılabilen bir dizin olduğu takdirde, birileri bir günlük
      dosyasını bir sistem dosyasına sembolik bağ haline getirerek root
      kullanıcısının bu dosyaya ilgisiz şeyler yazmasına sebep olabilir.
      Günlüklerin dosyaları herkes tarafından yazılabilir olduğu takdirde ise
      birileri dosyaya yanıltıcı veriler girebilir.</p>

<h2><a name="ssi" id="ssi">Sunucu Taraflı İçerik Yerleştirme</a></h2>
    

    <p>SSI sayfaları bir sunucu yöneticisi açısından çeşitli olası risklere
      kaynaklık edebilir.</p>

    <p>İlk risk, sunucu yükündeki artış olasılığıdır. Tüm SSI sayfaları,  SSI
      kodu içersin içermesin Apache tarafından çözümlenir. Bu küçük bir artış
      gibi görünürse de bir paylaşımlı sunucu ortamında önemli bir yük haline
      gelebilir.</p>

    <p>SSI sayfaları, CGI betikleriyle ilgili riskleri de taşır. <code>exec
      cmd</code> elemanı kullanılarak bir SSI sayfasından herhangi bir CGI
      betiğini veya bir sistem programını Apache’nin aidiyetinde olduğu
      kullanıcının yetkisiyle çalıştırmak mümkündür.</p>

    <p>SSI sayfalarının yararlı özelliklerinden yararlanırken güvenliğini de
      arttırmanın bazı yolları vardır.</p>

    <p>Sunucu yöneticisi, bir başıbozuk SSI sayfasının sebep olabileceği
      zararları bertaraf etmek için <a href="#cgi">CGI Genelinde</a>
      bölümünde açıklandığı gibi <a href="../suexec.html">suexec</a>’i etkin
      kılabilir.</p>

    <p>SSI sayfalarını <code>.html</code> veya <code>.htm</code>
      uzantılarıyla etkinleştirmek tehlikeli olabilir. Bu özellikle
      paylaşımlı ve yüksek trafikli bir sunucu ortamında önemlidir. SSI
      sayfalarını normal sayfalardan farklı olarak <code>.shtml</code> gibi
      bildik bir uzantıyla etkinleştirmek gerekir. Bu, sunucu yükünü asgari
      düzeyde tutmaya ve risk yönetimini kolaylaştırmaya yarar.</p>

    <p>Diğer bir çözüm de SSI sayfalarından betik ve program çalıştırmayı
      iptal etmektir. Bu, <code class="directive"><a href="../mod/core.html#options">Options</a></code>
      yönergesine değer olarak <code>Includes</code> yerine
      <code>IncludesNOEXEC</code> vererek sağlanır. Ancak, eğer betiklerin
      bulunduğu dizinde <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>
      yönergesiyle CGI betiklerinin çalışması mümkün kılınmışsa,
      kullanıcıların <code>&lt;--#include virtual="..." --&gt;</code> ile bu
      betikleri  çalıştırabileceklerine dikkat ediniz.</p>

      yakalama becerinize güvenmek zorundasınız. CGI betikleri esasen
      sisteminizdeki komutları site kullanıcılarının izinleriyle
      çalıştırırlar. Bu bakımdan dikkatle denenmedikleri takdirde oldukça
      tehlikeli olabilirler.</p>

    <p>CGI betiklerinin hepsi aynı kullanıcının aidiyetinde çalışırsa diğer
      betiklerle aralarında çelişkilerin ortaya çıkması ister istemez
      kaçınılmazdır. Örneğin A kullanıcısının B kullanıcısına garezi varsa
      bir betik yazıp B’nin CGI veritabanını silebilir. Bu gibi durumların
      ortaya çıkmaması için betiklerin farklı kullanıcıların aidiyetlerinde
      çalışmasını sağlayan ve 1.2 sürümünden beri Apache ile dağıtılan <a href="../suexec.html">suEXEC</a> diye bir program vardır. Başka bir yol

    <p>Güvenliği gerçekten sıkı tutmak istiyorsanız, kullanıcılarınızın
      yapılandırmanızdaki güvenlik ayarlarını geçersiz kılmak için
      <code>.htaccess</code> dosyalarını kullanabilmelerinin de önüne
      geçmelisiniz. Bunu yapmanın tek bir yolu vardır.</p>

    <p>Sunucu yapılandırma dosyanıza şunu yerleştirin:</p>

    <pre class="prettyprint lang-config">&lt;Directory "/"&gt;
    AllowOverride None
&lt;/Directory&gt;</pre>


    <p>Böylece, belli dizinlerde özellikle etkinleştirilmedikçe bütün
      dizinlerde <code>.htaccess</code> dosyalarının kullanımını engellemiş
      olursunuz.</p>

    <p>Bu ayar Apache 2.3.9 itibariyle öntanımlıdır.</p>

<div class="section">
<h2><a name="protectserverfiles" id="protectserverfiles">Sunucu dosyalarının öntanımlı olarak korunması</a></h2>
    

    <p>Apache’nin ister istemez yanlış anlaşılan yönlerinden biri öntanımlı
      erişim özelliğidir. Yani siz aksine bir şeyler yapmadıkça, sunucu normal
      URL eşleme kurallarını kullanarak bir dosyayı bulabildiği sürece onu
      istemciye sunacaktır.</p>

    <p>Örneğin, aşağıdaki durumu ele alalım:</p>

    <div class="example"><p><code>
      # cd /; ln -s / public_html
    </code></p></div>

    <p>Ve, tarayıcınıza <code>http://localhost/~root/</code> yazın.</p>

    <p>Böylece, istemcilerin tüm dosya sisteminizi gezmelerine izin vermiş
      olursunuz. Bu işlemin sonuçlarının önünü almak için sunucu yapılandırma
      dosyanıza şunları yazın:</p>

    <pre class="prettyprint lang-config">&lt;Directory "/"&gt;
    Require all denied
&lt;/Directory&gt;</pre>


    <p>Bu suretle, dosya sisteminize öntanımlı erişimi yasaklamış olursunuz.
      Erişime izin vermek istediğiniz dizinler için uygun <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> bölümleri eklemeniz yeterli
      olacaktır. Örnek:</p>

    <pre class="prettyprint lang-config">&lt;Directory "/usr/users/*/public_html"&gt;
    Require all granted
&lt;/Directory&gt;
&lt;Directory "/usr/local/httpd"&gt;
    Require all granted
&lt;/Directory&gt;</pre>


    <p><code class="directive"><a href="../mod/core.html#location">Location</a></code> ve <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> yönergelerinin etkileşimine de
      özellikle önem vermelisiniz; örneğin <code>&lt;Directory "/"&gt;</code>
      erişimi yasaklarken bir <code>&lt;Location "/"&gt;</code> yönergesi bunu
      ortadan kaldırabilir.</p>

    <p><code class="directive"><a href="../mod/mod_userdir.html#userdir">UserDir</a></code> yönergesi de size
      buna benzer bir oyun oynayabilir; yönergeye <code>./</code> atamasını
      yaparsanız, root kullanıcısı söz konusu olduğunda yukarıda ilk örnekteki
      durumla karşılaşırız. Sunucu yapılandırma dosyanızda aşağıdaki satırın
      mutlaka bulunmasını öneririz:</p>

    <pre class="prettyprint lang-config">UserDir disabled root</pre>

      sadece olup biteni raporlamakla kalmaz, sunucunuza ne tür saldırılar
      yapıldığını ve güvenlik seviyenizin yeterli olup olmadığını anlamanızı da
      sağlarlar.</p>

    <p>Bazı örnekler:</p>

    <div class="example"><p><code>

    <div class="example"><p><code>

      by server configuration: /usr/local/apache/htdocs/.htpasswd
    </code></p></div>

    <p>Gördüğünüz gibi günlük dosyaları sadece ne olup bittiğini raporlar, bu
      bakımdan eğer istemci <code>.htpasswd</code> dosyasına erişebiliyorsa <a href="../logs.html#accesslog">erişim günlüğünüzde</a> şuna benzer bir
      kayıt görürsünüz:</p>

      foo.example.com - - [12/Jul/2002:01:59:13 +0200] "GET /.htpasswd HTTP/1.1"
    </code></p></div>

    <p>Bu, sunucu yapılandırma dosyanızda aşağıdaki yapılandırmayı iptal

<h2><a name="uptodate" id="uptodate">Keep up to Date</a></h2>

    <p>The Apache HTTP Server has a good record for security and a
    developer community highly concerned about security issues.  But
    it is inevitable that some problems -- small or large -- will be
    discovered in software after it is released.  For this reason, it
    is crucial to keep aware of updates to the software.  If you have
    obtained your version of the HTTP Server directly from Apache, we
    highly recommend you subscribe to the <a href="http://httpd.apache.org/lists.html#http-announce">Apache
    HTTP Server Announcements List</a> where you can keep informed of
    new releases and security updates.  Similar services are available
    from most third-party distributors of Apache software.</p>

    <p>Of course, most times that a web server is compromised, it is
    not because of problems in the HTTP Server code.  Rather, it comes
    from problems in add-on code, CGI scripts, or the underlying
    Operating System.  You must therefore stay aware of problems and
    updates with all the software on your system.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="dos" id="dos">Denial of Service (DoS) attacks</a></h2>

    

    <p>All network servers can be subject to denial of service attacks
    that attempt to prevent responses to clients by tying up the
    resources of the server.  It is not possible to prevent such
    attacks entirely, but you can do certain things to mitigate the
    problems that they create.</p>

    <p>Often the most effective anti-DoS tool will be a firewall or
    other operating-system configurations.  For example, most
    firewalls can be configured to restrict the number of simultaneous
    connections from any individual IP address or network, thus
    preventing a range of simple attacks.  Of course this is no help
    against Distributed Denial of Service attacks (DDoS).</p>

    <p>There are also certain Apache HTTP Server configuration
    settings that can help mitigate problems:</p>

    <ul>
      <li>The <code class="directive"><a href="../mod/mod_reqtimeout.html#requestreadtimeout">RequestReadTimeout</a></code>
      directive allows to limit the time a client may take to send the
      request.</li>

      <li>The <code class="directive"><a href="../mod/core.html#timeout">TimeOut</a></code> directive
      should be lowered on sites that are subject to DoS attacks.
      Setting this to as low as a few seconds may be appropriate.
      As <code class="directive"><a href="../mod/core.html#timeout">TimeOut</a></code> is currently
      used for several different operations, setting it to a low value
      introduces problems with long running CGI scripts.</li>

      <li>The <code class="directive"><a href="../mod/core.html#keepalivetimeout">KeepAliveTimeout</a></code>
      directive may be also lowered on sites that are subject to DoS
      attacks.  Some sites even turn off the keepalives completely via
      <code class="directive"><a href="../mod/core.html#keepalive">KeepAlive</a></code>, which has of course
      other drawbacks on performance.</li>

      <li>The values of various timeout-related directives provided by
      other modules should be checked.</li>

      <li>The directives
      <code class="directive"><a href="../mod/core.html#limitrequestbody">LimitRequestBody</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestfields">LimitRequestFields</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestfieldsize">LimitRequestFieldSize</a></code>,
      <code class="directive"><a href="../mod/core.html#limitrequestline">LimitRequestLine</a></code>, and
      <code class="directive"><a href="../mod/core.html#limitxmlrequestbody">LimitXMLRequestBody</a></code>
      should be carefully configured to limit resource consumption
      triggered by client input.</li>

      <li>On operating systems that support it, make sure that you use
      the <code class="directive"><a href="../mod/core.html#acceptfilter">AcceptFilter</a></code> directive
      to offload part of the request processing to the operating
      system.  This is active by default in Apache httpd, but may
      require reconfiguration of your kernel.</li>

      <li>Tune the <code class="directive"><a href="../mod/mpm_common.html#maxrequestworkers">MaxRequestWorkers</a></code> directive to allow
      the server to handle the maximum number of simultaneous
      connections without running out of resources.  See also the <a href="perf-tuning.html">performance tuning
      documentation</a>.</li>

      <li>The use of a threaded <a href="../mpm.html">mpm</a> may
      allow you to handle more simultaneous connections, thereby
      mitigating DoS attacks.  Further, the
      <code class="module"><a href="../mod/event.html">event</a></code> mpm
      uses asynchronous processing to avoid devoting a thread to each
      connection. Due to the nature of the OpenSSL library the
      <code class="module"><a href="../mod/event.html">event</a></code> mpm is currently incompatible with
      <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> and other input filters. In these
      cases it falls back to the behaviour of the
      <code class="module"><a href="../mod/worker.html">worker</a></code> mpm.</li>

      <li>There are a number of third-party modules available
      that can restrict certain client behaviors and thereby mitigate
      DoS problems.</li>

    </ul>

<div class="section">
<h2><a name="serverroot" id="serverroot">Permissions on ServerRoot Directories</a></h2>

    

    <p>In typical operation, Apache is started by the root user, and it
    switches to the user defined by the <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code> directive to serve hits. As is the
    case with any command that root executes, you must take care that it is
    protected from modification by non-root users. Not only must the files
    themselves be writeable only by root, but so must the directories, and
    parents of all directories. For example, if you choose to place
    ServerRoot in  <code>/usr/local/apache</code> then it is suggested that
    you create that directory as root, with commands like these:</p>

    <div class="example"><p><code>
      mkdir /usr/local/apache <br />
      cd /usr/local/apache <br />
      mkdir bin conf logs <br />
      chown 0 . bin conf logs <br />
      chgrp 0 . bin conf logs <br />
      chmod 755 . bin conf logs
    </code></p></div>

    <p>It is assumed that <code>/</code>, <code>/usr</code>, and
    <code>/usr/local</code> are only modifiable by root. When you install the
    <code class="program"><a href="../programs/httpd.html">httpd</a></code> executable, you should ensure that it is
    similarly protected:</p>

    <div class="example"><p><code>
      cp httpd /usr/local/apache/bin <br />
      chown 0 /usr/local/apache/bin/httpd <br />
      chgrp 0 /usr/local/apache/bin/httpd <br />
      chmod 511 /usr/local/apache/bin/httpd
    </code></p></div>

    <p>You can create an htdocs subdirectory which is modifiable by other
    users -- since root never executes any files out of there, and shouldn't
    be creating files in there.</p>

    <p>If you allow non-root users to modify any files that root either
    executes or writes on then you open your system to root compromises.
    For example, someone could replace the <code class="program"><a href="../programs/httpd.html">httpd</a></code> binary so
    that the next time you start it, it will execute some arbitrary code. If
    the logs directory is writeable (by a non-root user), someone could replace
    a log file with a symlink to some other system file, and then root
    might overwrite that file with arbitrary data. If the log files
    themselves are writeable (by a non-root user), then someone may be
    able to overwrite the log itself with bogus data.</p>

<div class="section">
<h2><a name="ssi" id="ssi">Server Side Includes</a></h2>

    

    <p>Server Side Includes (SSI) present a server administrator with
    several potential security risks.</p>

    <p>The first risk is the increased load on the server. All
    SSI-enabled files have to be parsed by Apache, whether or not
    there are any SSI directives included within the files. While this
    load increase is minor, in a shared server environment it can become
    significant.</p>

    <p>SSI files also pose the same risks that are associated with CGI
    scripts in general. Using the <code>exec cmd</code> element, SSI-enabled
    files can execute any CGI script or program under the permissions of the
    user and group Apache runs as, as configured in
    <code>httpd.conf</code>.</p>

    <p>There are ways to enhance the security of SSI files while still
    taking advantage of the benefits they provide.</p>

    <p>To isolate the damage a wayward SSI file can cause, a server
    administrator can enable <a href="../suexec.html">suexec</a> as
    described in the <a href="#cgi">CGI in General</a> section.</p>

    <p>Enabling SSI for files with <code>.html</code> or <code>.htm</code>
    extensions can be dangerous. This is especially true in a shared, or high
    traffic, server environment. SSI-enabled files should have a separate
    extension, such as the conventional <code>.shtml</code>. This helps keep
    server load at a minimum and allows for easier management of risk.</p>

    <p>Another solution is to disable the ability to run scripts and
    programs from SSI pages. To do this replace <code>Includes</code>
    with <code>IncludesNOEXEC</code> in the <code class="directive"><a href="../mod/core.html#options">Options</a></code> directive.  Note that users may
    still use <code>&lt;--#include virtual="..." --&gt;</code> to execute CGI
    scripts if these scripts are in directories designated by a <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code> directive.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="cgi" id="cgi">CGI in General</a></h2>

    

    <p>First of all, you always have to remember that you must trust the
    writers of the CGI scripts/programs or your ability to spot potential
    security holes in CGI, whether they were deliberate or accidental. CGI
    scripts can run essentially arbitrary commands on your system with the
    permissions of the web server user and can therefore be extremely
    dangerous if they are not carefully checked.</p>

    <p>All the CGI scripts will run as the same user, so they have potential
    to conflict (accidentally or deliberately) with other scripts e.g. User
    A hates User B, so he writes a script to trash User B's CGI database. One
    program which can be used to allow scripts to run as different users is
    <a href="../suexec.html">suEXEC</a> which is included with Apache as of
    1.2 and is called from special hooks in the Apache server code. Another
    popular way of doing this is with
    <a href="http://cgiwrap.sourceforge.net/">CGIWrap</a>.</p>

<h2><a name="nsaliasedcgi" id="nsaliasedcgi">Non Script Aliased CGI</a></h2>

    

    <p>Allowing users to execute CGI scripts in any directory should only be
    considered if:</p>

    <ul>
      <li>You trust your users not to write scripts which will deliberately
          or accidentally expose your system to an attack.</li>
      <li>You consider security at your site to be so feeble in other areas,
          as to make one more potential hole irrelevant.</li>
      <li>You have no users, and nobody ever visits your server.</li>

<div class="section">
<h2><a name="saliasedcgi" id="saliasedcgi">Script Aliased CGI</a></h2>

    

    <p>Limiting CGI to special directories gives the admin control over what
    goes into those directories. This is inevitably more secure than non
    script aliased CGI, but only if users with write access to the
    directories are trusted or the admin is willing to test each
    new CGI script/program for potential security holes.</p>

    <p>Most sites choose this option over the non script aliased CGI
    approach.</p>

<h2><a name="dynamic" id="dynamic">Other sources of dynamic content</a></h2>

  

  <p>Embedded scripting options which run as part of the server itself,
  such as <code>mod_php</code>, <code>mod_perl</code>, <code>mod_tcl</code>,
  and <code>mod_python</code>, run under the identity of the server itself
  (see the <code class="directive"><a href="../mod/mod_unixd.html#user">User</a></code> directive), and
  therefore scripts executed by these engines potentially can access anything
  the server user can. Some scripting engines may provide restrictions, but
  it is better to be safe and assume not.</p>

<div class="section">
<h2><a name="dynamicsec" id="dynamicsec">Dynamic content security</a></h2>

  

  <p>When setting up dynamic content, such as <code>mod_php</code>,
  <code>mod_perl</code> or <code>mod_python</code>, many security considerations
  get out of the scope of <code>httpd</code> itself, and you need to consult
  documentation from those modules. For example, PHP lets you setup <a href="http://www.php.net/manual/en/ini.sect.safe-mode.php">Safe Mode</a>,
  which is most usually disabled by default. Another example is <a href="http://www.hardened-php.net/suhosin/">Suhosin</a>, a PHP addon for more
  security. For more information about those, consult each project
  documentation.</p>

  <p>At the Apache level, a module named <a href="http://modsecurity.org/">mod_security</a>
  can be seen as a HTTP firewall and, provided you configure it finely enough,
  can help you enhance your dynamic content security.</p>

<h2><a name="systemsettings" id="systemsettings">Protecting System Settings</a></h2>

    

    <p>To run a really tight ship, you'll want to stop users from setting
    up <code>.htaccess</code> files which can override security features
    you've configured. Here's one way to do it.</p>

    <p>In the server configuration file, put</p>

    <pre class="prettyprint lang-config">&lt;Directory "/"&gt;
    AllowOverride None
&lt;/Directory&gt;</pre>


    <p>This prevents the use of <code>.htaccess</code> files in all
    directories apart from those specifically enabled.</p>

    <p>Note that this setting is the default since Apache 2.3.9.</p>

  </div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="protectserverfiles" id="protectserverfiles">Protect Server Files by Default</a></h2>

    

    <p>One aspect of Apache which is occasionally misunderstood is the
    feature of default access. That is, unless you take steps to change it,
    if the server can find its way to a file through normal URL mapping
    rules, it can serve it to clients.</p>

    <p>For instance, consider the following example:</p>

    <div class="example"><p><code>
      # cd /; ln -s / public_html <br />
      Accessing <code>http://localhost/~root/</code>
    </code></p></div>

    <p>This would allow clients to walk through the entire filesystem. To
    work around this, add the following block to your server's
    configuration:</p>

    <pre class="prettyprint lang-config">&lt;Directory "/"&gt;
    Require all denied
&lt;/Directory&gt;</pre>


    <p>This will forbid default access to filesystem locations. Add
    appropriate <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> blocks to
    allow access only in those areas you wish. For example,</p>

    <pre class="prettyprint lang-config">&lt;Directory "/usr/users/*/public_html"&gt;
    Require all granted
&lt;/Directory&gt;
&lt;Directory "/usr/local/httpd"&gt;
    Require all granted
&lt;/Directory&gt;</pre>


    <p>Pay particular attention to the interactions of <code class="directive"><a href="../mod/core.html#location">Location</a></code> and <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> directives; for instance, even
    if <code>&lt;Directory "/"&gt;</code> denies access, a <code>
    &lt;Location "/"&gt;</code> directive might overturn it.</p>

    <p>Also be wary of playing games with the <code class="directive"><a href="../mod/mod_userdir.html#userdir">UserDir</a></code> directive; setting it to
    something like <code>./</code> would have the same effect, for root, as
    the first example above. We strongly
    recommend that you include the following line in your server
    configuration files:</p>

    <pre class="prettyprint lang-config">UserDir disabled root</pre>

<h2><a name="watchyourlogs" id="watchyourlogs">Watching Your Logs</a></h2>

    

    <p>To keep up-to-date with what is actually going on against your server
    you have to check the <a href="../logs.html">Log Files</a>.  Even though
    the log files only reports what has already happened, they will give you
    some understanding of what attacks is thrown against the server and
    allow you to check if the necessary level of security is present.</p>

    <p>A couple of examples:</p>

    <div class="example"><p><code>
      grep -c "/jsp/source.jsp?/jsp/ /jsp/source.jsp??" access_log <br />
      grep "client denied" error_log | tail -n 10
    </code></p></div>

    <p>The first example will list the number of attacks trying to exploit the
    <a href="http://online.securityfocus.com/bid/4876/info/">Apache Tomcat
    Source.JSP Malformed Request Information Disclosure Vulnerability</a>,
    the second example will list the ten last denied clients, for example:</p>

    <div class="example"><p><code>
      [Thu Jul 11 17:18:39 2002] [error] [client foo.example.com] client denied
      by server configuration: /usr/local/apache/htdocs/.htpasswd
    </code></p></div>

    <p>As you can see, the log files only report what already has happened, so
    if the client had been able to access the <code>.htpasswd</code> file you
    would have seen something similar to:</p>

    <div class="example"><p><code>
      foo.example.com - - [12/Jul/2002:01:59:13 +0200] "GET /.htpasswd HTTP/1.1"
    </code></p></div>

    <p>in your <a href="../logs.html#accesslog">Access Log</a>. This means

<h2><a name="merging" id="merging">Merging of configuration sections</a></h2>

    

    <p> The merging of configuration sections is complicated and sometimes
    directive specific.  Always test your changes when creating dependencies
    on how directives are merged.</p>

    <p> For modules that don't implement any merging logic, such as
    <code class="module"><a href="../mod/mod_access_compat.html">mod_access_compat</a></code>, the behavior in later sections
    depends on whether the later section has any directives
    from the module.  The configuration is inherited until a change is made,
    at which point the configuration is <em>replaced</em> and not merged.</p>

    <p>Apache 2.x is a general-purpose webserver, designed to
    provide a balance of flexibility, portability, and performance.
    Although it has not been designed specifically to set benchmark
    records, Apache 2.x is capable of high performance in many
    real-world situations.</p>

    <p>Compared to Apache 1.3, release 2.x contains many additional
    optimizations to increase throughput and scalability. Most of
    these improvements are enabled by default. However, there are
    compile-time and run-time configuration choices that can
    significantly affect performance. This document describes the
    options that a server administrator can configure to tune the
    performance of an Apache 2.x installation. Some of these
    configuration options enable the httpd to better take advantage
    of the capabilities of the hardware and OS, while others allow
    the administrator to trade functionality for speed.</p>

<h2><a name="hardware" id="hardware">Hardware and Operating System Issues</a></h2>

    

    <p>The single biggest hardware issue affecting webserver
    performance is RAM. A webserver should never ever have to swap,
    as swapping increases the latency of each request beyond a point
    that users consider "fast enough". This causes users to hit
    stop and reload, further increasing the load. You can, and
    should, control the <code class="directive"><a href="../mod/mpm_common.html#maxrequestworkers">MaxRequestWorkers</a></code> setting so that your server
    does not spawn so many children that it starts swapping. The procedure
    for doing this is simple: determine the size of your average Apache
    process, by looking at your process list via a tool such as
    <code>top</code>, and divide this into your total available memory,
    leaving some room for other processes.</p>

    <p>Beyond that the rest is mundane: get a fast enough CPU, a
    fast enough network card, and fast enough disks, where "fast
    enough" is something that needs to be determined by
    experimentation.</p>

    <p>Operating system choice is largely a matter of local
    concerns. But some guidelines that have proven generally
    useful are:</p>

    <ul>
      <li>
        <p>Run the latest stable release and patch level of the
        operating system that you choose. Many OS suppliers have
        introduced significant performance improvements to their
        TCP stacks and thread libraries in recent years.</p>
      </li>

      <li>
        <p>If your OS supports a <code>sendfile(2)</code> system
        call, make sure you install the release and/or patches
        needed to enable it. (With Linux, for example, this means
        using Linux 2.4 or later. For early releases of Solaris 8,
        you may need to apply a patch.) On systems where it is
        available, <code>sendfile</code> enables Apache 2 to deliver
        static content faster and with lower CPU utilization.</p>
      </li>
    </ul>

    <h3><a name="dns" id="dns">HostnameLookups and other DNS considerations</a></h3>

      

      <p>Prior to Apache 1.3, <code class="directive"><a href="../mod/core.html#hostnamelookups">HostnameLookups</a></code> defaulted to <code>On</code>.
      This adds latency to every request because it requires a
      DNS lookup to complete before the request is finished. In
      Apache 1.3 this setting defaults to <code>Off</code>. If you need
      to have addresses in your log files resolved to hostnames, use the
      <code class="program"><a href="../programs/logresolve.html">logresolve</a></code>
      program that comes with Apache, or one of the numerous log
      reporting packages which are available.</p>

      <p>It is recommended that you do this sort of postprocessing of
      your log files on some machine other than the production web
      server machine, in order that this activity not adversely affect
      server performance.</p>

      <p>If you use any <code><code class="directive"><a href="../mod/mod_access_compat.html#allow">Allow</a></code> from domain</code> or <code><code class="directive"><a href="../mod/mod_access_compat.html#deny">Deny</a></code> from domain</code>
      directives (i.e., using a hostname, or a domain name, rather than
      an IP address) then you will pay for
      two DNS lookups (a reverse, followed by a forward lookup
      to make sure that the reverse is not being spoofed). For best
      performance, therefore, use IP addresses, rather than names, when
      using these directives, if possible.</p>

      <p>Note that it's possible to scope the directives, such as
      within a <code>&lt;Location "/server-status"&gt;</code> section.
      In this case the DNS lookups are only performed on requests
      matching the criteria. Here's an example which disables lookups
      except for <code>.html</code> and <code>.cgi</code> files:</p>

      <pre class="prettyprint lang-config">HostnameLookups off
&lt;Files ~ "\.(html|cgi)$"&gt;
  HostnameLookups on
&lt;/Files&gt;</pre>


      <p>But even still, if you just need DNS names in some CGIs you
      could consider doing the <code>gethostbyname</code> call in the
      specific CGIs that need it.</p>

    

    <h3><a name="symlinks" id="symlinks">FollowSymLinks and SymLinksIfOwnerMatch</a></h3>

      

      <p>Wherever in your URL-space you do not have an <code>Options
      FollowSymLinks</code>, or you do have an <code>Options
      SymLinksIfOwnerMatch</code>, Apache will need to issue extra
      system calls to check up on symlinks. (One extra call per
      filename component.) For example, if you had:</p>

      <pre class="prettyprint lang-config">DocumentRoot "/www/htdocs"
&lt;Directory "/"&gt;
  Options SymLinksIfOwnerMatch
&lt;/Directory&gt;</pre>


      <p>and a request is made for the URI <code>/index.html</code>,
      then Apache will perform <code>lstat(2)</code> on
      <code>/www</code>, <code>/www/htdocs</code>, and
      <code>/www/htdocs/index.html</code>. The results of these
      <code>lstats</code> are never cached, so they will occur on
      every single request. If you really desire the symlinks
      security checking, you can do something like this:</p>

      <pre class="prettyprint lang-config">DocumentRoot "/www/htdocs"
&lt;Directory "/"&gt;
  Options FollowSymLinks
&lt;/Directory&gt;

&lt;Directory "/www/htdocs"&gt;
  Options -FollowSymLinks +SymLinksIfOwnerMatch
&lt;/Directory&gt;</pre>


      <p>This at least avoids the extra checks for the
      <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> path.
      Note that you'll need to add similar sections if you
      have any <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> or
      <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> paths
      outside of your document root. For highest performance,
      and no symlink protection, set <code>FollowSymLinks</code>
      everywhere, and never set <code>SymLinksIfOwnerMatch</code>.</p>

    

    <h3><a name="htaccess" id="htaccess">AllowOverride</a></h3>

      

      <p>Wherever in your URL-space you allow overrides (typically
      <code>.htaccess</code> files), Apache will attempt to open
      <code>.htaccess</code> for each filename component. For
      example,</p>

      <pre class="prettyprint lang-config">DocumentRoot "/www/htdocs"
&lt;Directory "/"&gt;
  AllowOverride all
&lt;/Directory&gt;</pre>


      <p>and a request is made for the URI <code>/index.html</code>.
      Then Apache will attempt to open <code>/.htaccess</code>,
      <code>/www/.htaccess</code>, and
      <code>/www/htdocs/.htaccess</code>. The solutions are similar
      to the previous case of <code>Options FollowSymLinks</code>.
      For highest performance use <code>AllowOverride None</code>
      everywhere in your filesystem.</p>

    

    <h3><a name="negotiation" id="negotiation">Negotiation</a></h3>

      

      <p>If at all possible, avoid content negotiation if you're
      really interested in every last ounce of performance. In
      practice the benefits of negotiation outweigh the performance
      penalties. There's one case where you can speed up the server.
      Instead of using a wildcard such as:</p>

      <pre class="prettyprint lang-config">DirectoryIndex index</pre>


      <p>Use a complete list of options:</p>

      <pre class="prettyprint lang-config">DirectoryIndex index.cgi index.pl index.shtml index.html</pre>


      <p>where you list the most common choice first.</p>

      <p>Also note that explicitly creating a <code>type-map</code>
      file provides better performance than using
      <code>MultiViews</code>, as the necessary information can be
      determined by reading this single file, rather than having to
      scan the directory for files.</p>

    <p>If your site needs content negotiation, consider using
    <code>type-map</code> files, rather than the <code>Options
    MultiViews</code> directive to accomplish the negotiation. See the
    <a href="../content-negotiation.html">Content Negotiation</a>
    documentation for a full discussion of the methods of negotiation,
    and instructions for creating <code>type-map</code> files.</p>

    

    <h3>Memory-mapping</h3>

      

      <p>In situations where Apache 2.x needs to look at the contents
      of a file being delivered--for example, when doing server-side-include
      processing--it normally memory-maps the file if the OS supports
      some form of <code>mmap(2)</code>.</p>

      <p>On some platforms, this memory-mapping improves performance.
      However, there are cases where memory-mapping can hurt the performance
      or even the stability of the httpd:</p>

      <ul>
        <li>
          <p>On some operating systems, <code>mmap</code> does not scale
          as well as <code>read(2)</code> when the number of CPUs increases.
          On multiprocessor Solaris servers, for example, Apache 2.x sometimes
          delivers server-parsed files faster when <code>mmap</code> is disabled.</p>
        </li>

        <li>
          <p>If you memory-map a file located on an NFS-mounted filesystem
          and a process on another NFS client machine deletes or truncates
          the file, your process may get a bus error the next time it tries
          to access the mapped file content.</p>
        </li>
      </ul>

      <p>For installations where either of these factors applies, you
      should use <code>EnableMMAP off</code> to disable the memory-mapping
      of delivered files. (Note: This directive can be overridden on
      a per-directory basis.)</p>

    

    <h3>Sendfile</h3>

      

      <p>In situations where Apache 2.x can ignore the contents of the file
      to be delivered -- for example, when serving static file content --
      it normally uses the kernel sendfile support for the file if the OS
      supports the <code>sendfile(2)</code> operation.</p>

      <p>On most platforms, using sendfile improves performance by eliminating
      separate read and send mechanics.  However, there are cases where using
      sendfile can harm the stability of the httpd:</p>

      <ul>
        <li>
          <p>Some platforms may have broken sendfile support that the build
          system did not detect, especially if the binaries were built on
          another box and moved to such a machine with broken sendfile support.</p>
        </li>
        <li>
          <p>With an NFS-mounted filesystem, the kernel may be unable
          to reliably serve the network file through its own cache.</p>
        </li>
      </ul>

      <p>For installations where either of these factors applies, you
      should use <code>EnableSendfile off</code> to disable sendfile
      delivery of file contents. (Note: This directive can be overridden
      on a per-directory basis.)</p>

    

    <h3><a name="process" id="process">Process Creation</a></h3>

      

      <p>Prior to Apache 1.3 the <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>, <code class="directive"><a href="../mod/prefork.html#maxspareservers">MaxSpareServers</a></code>, and <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> settings all had drastic effects on
      benchmark results. In particular, Apache required a "ramp-up"
      period in order to reach a number of children sufficient to serve
      the load being applied. After the initial spawning of
      <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> children,
      only one child per second would be created to satisfy the
      <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>
      setting. So a server being accessed by 100 simultaneous
      clients, using the default <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> of <code>5</code> would take on
      the order of 95 seconds to spawn enough children to handle
      the load. This works fine in practice on real-life servers
      because they aren't restarted frequently. But it does really
      poorly on benchmarks which might only run for ten minutes.</p>

      <p>The one-per-second rule was implemented in an effort to
      avoid swamping the machine with the startup of new children. If
      the machine is busy spawning children, it can't service
      requests. But it has such a drastic effect on the perceived
      performance of Apache that it had to be replaced. As of Apache
      1.3, the code will relax the one-per-second rule. It will spawn
      one, wait a second, then spawn two, wait a second, then spawn
      four, and it will continue exponentially until it is spawning
      32 children per second. It will stop whenever it satisfies the
      <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>
      setting.</p>

      <p>This appears to be responsive enough that it's almost
      unnecessary to twiddle the <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>, <code class="directive"><a href="../mod/prefork.html#maxspareservers">MaxSpareServers</a></code> and <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> knobs. When more than 4 children are
      spawned per second, a message will be emitted to the
      <code class="directive"><a href="../mod/core.html#errorlog">ErrorLog</a></code>. If you
      see a lot of these errors, then consider tuning these settings.
      Use the <code class="module"><a href="../mod/mod_status.html">mod_status</a></code> output as a guide.</p>

    <p>Related to process creation is process death induced by the
    <code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code>
    setting. By default this is <code>0</code>,
    which means that there is no limit to the number of connections
    handled per child. If your configuration currently has this set
    to some very low number, such as <code>30</code>, you may want to bump this
    up significantly. If you are running SunOS or an old version of
    Solaris, limit this to <code>10000</code> or so because of memory leaks.</p>

    <p>When keep-alives are in use, children will be kept busy
    doing nothing waiting for more requests on the already open
    connection. The default <code class="directive"><a href="../mod/core.html#keepalivetimeout">KeepAliveTimeout</a></code> of <code>5</code>
    seconds attempts to minimize this effect. The tradeoff here is
    between network bandwidth and server resources. In no event
    should you raise this above about <code>60</code> seconds, as <a href="http://www.hpl.hp.com/techreports/Compaq-DEC/WRL-95-4.html">
    most of the benefits are lost</a>.</p>

    <h3>Choosing an MPM</h3>

      

      <p>Apache 2.x supports pluggable concurrency models, called
      <a href="../mpm.html">Multi-Processing Modules</a> (MPMs).
      When building Apache, you must choose an MPM to use.  There
      are platform-specific MPMs for some platforms:
      <code class="module"><a href="../mod/mpm_netware.html">mpm_netware</a></code>,
      <code class="module"><a href="../mod/mpmt_os2.html">mpmt_os2</a></code>, and <code class="module"><a href="../mod/mpm_winnt.html">mpm_winnt</a></code>.  For
      general Unix-type systems, there are several MPMs from which
      to choose.  The choice of MPM can affect the speed and scalability
      of the httpd:</p>

      <ul>

        <li>The <code class="module"><a href="../mod/worker.html">worker</a></code> MPM uses multiple child
        processes with many threads each.  Each thread handles
        one connection at a time.  Worker generally is a good
        choice for high-traffic servers because it has a smaller
        memory footprint than the prefork MPM.</li>
        
        <li>The <code class="module"><a href="../mod/event.html">event</a></code> MPM is threaded like the 
        Worker MPM, but is designed to allow more requests to be 
        served simultaneously by passing off some processing work 
        to supporting threads, freeing up the main threads to work
        on new requests.</li>

        <li>The <code class="module"><a href="../mod/prefork.html">prefork</a></code> MPM uses multiple child
        processes with one thread each.  Each process handles
        one connection at a time.  On many systems, prefork is
        comparable in speed to worker, but it uses more memory.
        Prefork's threadless design has advantages over worker
        in some situations: it can be used with non-thread-safe
        third-party modules, and it is easier to debug on platforms
        with poor thread debugging support.</li>

      </ul>

      <p>For more information on these and other MPMs, please
      see the MPM <a href="../mpm.html">documentation</a>.</p>

    

    <h3><a name="modules" id="modules">Modules</a></h3>

        

        <p>Since memory usage is such an important consideration in
        performance, you should attempt to eliminate modules that you are
        not actually using. If you have built the modules as <a href="../dso.html">DSOs</a>, eliminating modules is a simple
        matter of commenting out the associated <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> directive for that module.
        This allows you to experiment with removing modules and seeing
        if your site still functions in their absence.</p>

        <p>If, on the other hand, you have modules statically linked
        into your Apache binary, you will need to recompile Apache in
        order to remove unwanted modules.</p>

        <p>An associated question that arises here is, of course, what
        modules you need, and which ones you don't. The answer here
        will, of course, vary from one web site to another. However, the
        <em>minimal</em> list of modules which you can get by with tends
        to include <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code>, <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code>,
        and <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>. <code>mod_log_config</code> is,
        of course, optional, as you can run a web site without log
        files. This is, however, not recommended.</p>

    

    <h3>Atomic Operations</h3>

      

      <p>Some modules, such as <code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code> and
      recent development builds of the worker MPM, use APR's
      atomic API.  This API provides atomic operations that can
      be used for lightweight thread synchronization.</p>

      <p>By default, APR implements these operations using the
      most efficient mechanism available on each target
      OS/CPU platform.  Many modern CPUs, for example, have
      an instruction that does an atomic compare-and-swap (CAS)
      operation in hardware.  On some platforms, however, APR
      defaults to a slower, mutex-based implementation of the
      atomic API in order to ensure compatibility with older
      CPU models that lack such instructions.  If you are
      building Apache for one of these platforms, and you plan
      to run only on newer CPUs, you can select a faster atomic
      implementation at build time by configuring Apache with
      the <code>--enable-nonportable-atomics</code> option:</p>

      <div class="example"><p><code>
        ./buildconf<br />
        ./configure --with-mpm=worker --enable-nonportable-atomics=yes
      </code></p></div>

      <p>The <code>--enable-nonportable-atomics</code> option is
      relevant for the following platforms:</p>

      <ul>

        <li>Solaris on SPARC<br />
            By default, APR uses mutex-based atomics on Solaris/SPARC.
            If you configure with <code>--enable-nonportable-atomics</code>,
            however, APR generates code that uses a SPARC v8plus opcode for
            fast hardware compare-and-swap.  If you configure Apache with
            this option, the atomic operations will be more efficient
            (allowing for lower CPU utilization and higher concurrency),
            but the resulting executable will run only on UltraSPARC
            chips.
        </li>

        <li>Linux on x86<br />
            By default, APR uses mutex-based atomics on Linux.  If you
            configure with <code>--enable-nonportable-atomics</code>,
            however, APR generates code that uses a 486 opcode for fast
            hardware compare-and-swap.  This will result in more efficient
            atomic operations, but the resulting executable will run only
            on 486 and later chips (and not on 386).
        </li>

      </ul>

    

    <h3>mod_status and ExtendedStatus On</h3>

      

      <p>If you include <code class="module"><a href="../mod/mod_status.html">mod_status</a></code> and you also set
      <code>ExtendedStatus On</code> when building and running
      Apache, then on every request Apache will perform two calls to
      <code>gettimeofday(2)</code> (or <code>times(2)</code>
      depending on your operating system), and (pre-1.3) several
      extra calls to <code>time(2)</code>. This is all done so that
      the status report contains timing indications. For highest
      performance, set <code>ExtendedStatus off</code> (which is the
      default).</p>

    

    <h3>accept Serialization - Multiple Sockets</h3>

      

    <div class="warning"><h3>Warning:</h3>
      <p>This section has not been fully updated
      to take into account changes made in the 2.x version of the
      Apache HTTP Server. Some of the information may still be
      relevant, but please use it with care.</p>
    </div>

      <p>This discusses a shortcoming in the Unix socket API. Suppose
      your web server uses multiple <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> statements to listen on either multiple
      ports or multiple addresses. In order to test each socket
      to see if a connection is ready, Apache uses
      <code>select(2)</code>. <code>select(2)</code> indicates that a
      socket has <em>zero</em> or <em>at least one</em> connection
      waiting on it. Apache's model includes multiple children, and
      all the idle ones test for new connections at the same time. A
      naive implementation looks something like this (these examples
      do not match the code, they're contrived for pedagogical
      purposes):</p>

      <pre class="prettyprint lang-c">        for (;;) {
          for (;;) {
            fd_set accept_fds;

            FD_ZERO (&amp;accept_fds);
            for (i = first_socket; i &lt;= last_socket; ++i) {
              FD_SET (i, &amp;accept_fds);
            }
            rc = select (last_socket+1, &amp;accept_fds, NULL, NULL, NULL);
            if (rc &lt; 1) continue;
            new_connection = -1;
            for (i = first_socket; i &lt;= last_socket; ++i) {
              if (FD_ISSET (i, &amp;accept_fds)) {
                new_connection = accept (i, NULL, NULL);
                if (new_connection != -1) break;
              }
            }
            if (new_connection != -1) break;
          }
          process_the(new_connection);
        }</pre>


      <p>But this naive implementation has a serious starvation problem.
      Recall that multiple children execute this loop at the same
      time, and so multiple children will block at
      <code>select</code> when they are in between requests. All
      those blocked children will awaken and return from
      <code>select</code> when a single request appears on any socket.
      (The number of children which awaken varies depending on the
      operating system and timing issues.) They will all then fall
      down into the loop and try to <code>accept</code> the
      connection. But only one will succeed (assuming there's still
      only one connection ready). The rest will be <em>blocked</em>
      in <code>accept</code>. This effectively locks those children
      into serving requests from that one socket and no other
      sockets, and they'll be stuck there until enough new requests
      appear on that socket to wake them all up. This starvation
      problem was first documented in <a href="http://bugs.apache.org/index/full/467">PR#467</a>. There
      are at least two solutions.</p>

      <p>One solution is to make the sockets non-blocking. In this
      case the <code>accept</code> won't block the children, and they
      will be allowed to continue immediately. But this wastes CPU
      time. Suppose you have ten idle children in
      <code>select</code>, and one connection arrives. Then nine of
      those children will wake up, try to <code>accept</code> the
      connection, fail, and loop back into <code>select</code>,
      accomplishing nothing. Meanwhile none of those children are
      servicing requests that occurred on other sockets until they
      get back up to the <code>select</code> again. Overall this
      solution does not seem very fruitful unless you have as many
      idle CPUs (in a multiprocessor box) as you have idle children
      (not a very likely situation).</p>

      <p>Another solution, the one used by Apache, is to serialize
      entry into the inner loop. The loop looks like this
      (differences highlighted):</p>

      <pre class="prettyprint lang-c">        for (;;) {
          <strong>accept_mutex_on ();</strong>
          for (;;) {
            fd_set accept_fds;
            
            FD_ZERO (&amp;accept_fds);
            for (i = first_socket; i &lt;= last_socket; ++i) {
              FD_SET (i, &amp;accept_fds);
            }
            rc = select (last_socket+1, &amp;accept_fds, NULL, NULL, NULL);
            if (rc &lt; 1) continue;
            new_connection = -1;
            for (i = first_socket; i &lt;= last_socket; ++i) {
              if (FD_ISSET (i, &amp;accept_fds)) {
                new_connection = accept (i, NULL, NULL);
                if (new_connection != -1) break;
              }
            }
            if (new_connection != -1) break;
          }
          <strong>accept_mutex_off ();</strong>
          process the new_connection;
        }</pre>


      <p><a id="serialize" name="serialize">The functions</a>
      <code>accept_mutex_on</code> and <code>accept_mutex_off</code>
      implement a mutual exclusion semaphore. Only one child can have
      the mutex at any time. There are several choices for
      implementing these mutexes. The choice is defined in
      <code>src/conf.h</code> (pre-1.3) or
      <code>src/include/ap_config.h</code> (1.3 or later). Some
      architectures do not have any locking choice made, on these
      architectures it is unsafe to use multiple
      <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>
      directives.</p>

      <p>The <code class="directive"><a href="../mod/core.html#mutex">Mutex</a></code> directive can
      be used to change the mutex implementation of the
      <code>mpm-accept</code> mutex at run-time.  Special considerations
      for different mutex implementations are documented with that
      directive.</p>

      <p>Another solution that has been considered but never
      implemented is to partially serialize the loop -- that is, let
      in a certain number of processes. This would only be of
      interest on multiprocessor boxes where it's possible that multiple
      children could run simultaneously, and the serialization
      actually doesn't take advantage of the full bandwidth. This is
      a possible area of future investigation, but priority remains
      low because highly parallel web servers are not the norm.</p>

      <p>Ideally you should run servers without multiple
      <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>
      statements if you want the highest performance.
      But read on.</p>

    

    <h3>accept Serialization - Single Socket</h3>

      

      <p>The above is fine and dandy for multiple socket servers, but
      what about single socket servers? In theory they shouldn't
      experience any of these same problems because all the children
      can just block in <code>accept(2)</code> until a connection
      arrives, and no starvation results. In practice this hides
      almost the same "spinning" behavior discussed above in the
      non-blocking solution. The way that most TCP stacks are
      implemented, the kernel actually wakes up all processes blocked
      in <code>accept</code> when a single connection arrives. One of
      those processes gets the connection and returns to user-space.
      The rest spin in the kernel and go back to sleep when they
      discover there's no connection for them. This spinning is
      hidden from the user-land code, but it's there nonetheless.
      This can result in the same load-spiking wasteful behavior
      that a non-blocking solution to the multiple sockets case
      can.</p>

      <p>For this reason we have found that many architectures behave
      more "nicely" if we serialize even the single socket case. So
      this is actually the default in almost all cases. Crude
      experiments under Linux (2.0.30 on a dual Pentium pro 166
      w/128Mb RAM) have shown that the serialization of the single
      socket case causes less than a 3% decrease in requests per
      second over unserialized single-socket. But unserialized
      single-socket showed an extra 100ms latency on each request.
      This latency is probably a wash on long haul lines, and only an
      issue on LANs. If you want to override the single socket
      serialization, you can define
      <code>SINGLE_LISTEN_UNSERIALIZED_ACCEPT</code>, and then
      single-socket servers will not serialize at all.</p>

    

    <h3>Lingering Close</h3>

      

      <p>As discussed in <a href="http://www.ics.uci.edu/pub/ietf/http/draft-ietf-http-connection-00.txt">
      draft-ietf-http-connection-00.txt</a> section 8, in order for
      an HTTP server to <strong>reliably</strong> implement the
      protocol, it needs to shut down each direction of the
      communication independently. (Recall that a TCP connection is
      bi-directional. Each half is independent of the other.)</p>

      <p>When this feature was added to Apache, it caused a flurry of
      problems on various versions of Unix because of shortsightedness.
      The TCP specification does not state that the <code>FIN_WAIT_2</code> 
      state has a timeout, but it doesn't prohibit it.
      On systems without the timeout, Apache 1.2 induces many sockets
      stuck forever in the <code>FIN_WAIT_2</code> state. In many cases this
      can be avoided by simply upgrading to the latest TCP/IP patches
      supplied by the vendor. In cases where the vendor has never
      released patches (<em>i.e.</em>, SunOS4 -- although folks with
      a source license can patch it themselves), we have decided to
      disable this feature.</p>

      <p>There are two ways to accomplish this. One is the socket
      option <code>SO_LINGER</code>. But as fate would have it, this
      has never been implemented properly in most TCP/IP stacks. Even
      on those stacks with a proper implementation (<em>i.e.</em>,
      Linux 2.0.31), this method proves to be more expensive (cputime)
      than the next solution.</p>

      <p>For the most part, Apache implements this in a function
      called <code>lingering_close</code> (in
      <code>http_main.c</code>). The function looks roughly like
      this:</p>

      <pre class="prettyprint lang-c">        void lingering_close (int s)
        {
          char junk_buffer[2048];
          
          /* shutdown the sending side */
          shutdown (s, 1);

          signal (SIGALRM, lingering_death);
          alarm (30);

          for (;;) {
            select (s for reading, 2 second timeout);
            if (error) break;
            if (s is ready for reading) {
              if (read (s, junk_buffer, sizeof (junk_buffer)) &lt;= 0) {
                break;
              }
              /* just toss away whatever is here */
            }
          }
          
          close (s);
        }</pre>


      <p>This naturally adds some expense at the end of a connection,
      but it is required for a reliable implementation. As HTTP/1.1
      becomes more prevalent, and all connections are persistent,
      this expense will be amortized over more requests. If you want
      to play with fire and disable this feature, you can define
      <code>NO_LINGCLOSE</code>, but this is not recommended at all.
      In particular, as HTTP/1.1 pipelined persistent connections
      come into use, <code>lingering_close</code> is an absolute
      necessity (and <a href="http://www.w3.org/Protocols/HTTP/Performance/Pipeline.html">
      pipelined connections are faster</a>, so you want to support
      them).</p>

    

    <h3>Scoreboard File</h3>

      

      <p>Apache's parent and children communicate with each other
      through something called the scoreboard. Ideally this should be
      implemented in shared memory. For those operating systems that
      we either have access to, or have been given detailed ports
      for, it typically is implemented using shared memory. The rest
      default to using an on-disk file. The on-disk file is not only
      slow, but it is unreliable (and less featured). Peruse the
      <code>src/main/conf.h</code> file for your architecture, and
      look for either <code>USE_MMAP_SCOREBOARD</code> or
      <code>USE_SHMGET_SCOREBOARD</code>. Defining one of those two
      (as well as their companions <code>HAVE_MMAP</code> and
      <code>HAVE_SHMGET</code> respectively) enables the supplied
      shared memory code. If your system has another type of shared
      memory, edit the file <code>src/main/http_main.c</code> and add
      the hooks necessary to use it in Apache. (Send us back a patch
      too, please.)</p>

      <div class="note">Historical note: The Linux port of Apache didn't start to
      use shared memory until version 1.2 of Apache. This oversight
      resulted in really poor and unreliable behavior of earlier
      versions of Apache on Linux.</div>

    

    <h3>DYNAMIC_MODULE_LIMIT</h3>

      

      <p>If you have no intention of using dynamically loaded modules
      (you probably don't if you're reading this and tuning your
      server for every last ounce of performance), then you should add
      <code>-DDYNAMIC_MODULE_LIMIT=0</code> when building your
      server. This will save RAM that's allocated only for supporting
      dynamically loaded modules.</p>

<div class="section">
<h2><a name="trace" id="trace">Appendix: Detailed Analysis of a Trace</a></h2>

    

    <p>Here is a system call trace of Apache 2.0.38 with the worker MPM
    on Solaris 8. This trace was collected using:</p>

    <div class="example"><p><code>
      truss -l -p <var>httpd_child_pid</var>.
    </code></p></div>

    <p>The <code>-l</code> option tells truss to log the ID of the
    LWP (lightweight process--Solaris' form of kernel-level thread)
    that invokes each system call.</p>

    <p>Other systems may have different system call tracing utilities
    such as <code>strace</code>, <code>ktrace</code>, or <code>par</code>.
    They all produce similar output.</p>

    <p>In this trace, a client has requested a 10KB static file
    from the httpd. Traces of non-static requests or requests
    with content negotiation look wildly different (and quite ugly
    in some cases).</p>

    <div class="example"><pre>/67:    accept(3, 0x00200BEC, 0x00200C0C, 1) (sleeping...)
/67:    accept(3, 0x00200BEC, 0x00200C0C, 1)            = 9</pre></div>

    <p>In this trace, the listener thread is running within LWP #67.</p>

    <div class="note">Note the lack of <code>accept(2)</code> serialization. On this
    particular platform, the worker MPM uses an unserialized accept by
    default unless it is listening on multiple ports.</div>

    <div class="example"><pre>/65:    lwp_park(0x00000000, 0)                         = 0
/67:    lwp_unpark(65, 1)                               = 0</pre></div>

    <p>Upon accepting the connection, the listener thread wakes up
    a worker thread to do the request processing. In this trace,
    the worker thread that handles the request is mapped to LWP #65.</p>

    <div class="example"><pre>/65:    getsockname(9, 0x00200BA4, 0x00200BC4, 1)       = 0</pre></div>

    <p>In order to implement virtual hosts, Apache needs to know
    the local socket address used to accept the connection. It
    is possible to eliminate this call in many situations (such
    as when there are no virtual hosts, or when
    <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> directives
    are used which do not have wildcard addresses). But
    no effort has yet been made to do these optimizations. </p>

    <div class="example"><pre>/65:    brk(0x002170E8)                                 = 0
/65:    brk(0x002190E8)                                 = 0</pre></div>

    <p>The <code>brk(2)</code> calls allocate memory from the heap.
    It is rare to see these in a system call trace, because the httpd
    uses custom memory allocators (<code>apr_pool</code> and
    <code>apr_bucket_alloc</code>) for most request processing.
    In this trace, the httpd has just been started, so it must
    call <code>malloc(3)</code> to get the blocks of raw memory
    with which to create the custom memory allocators.</p>

    <div class="example"><pre>/65:    fcntl(9, F_GETFL, 0x00000000)                   = 2
/65:    fstat64(9, 0xFAF7B818)                          = 0
/65:    getsockopt(9, 65535, 8192, 0xFAF7B918, 0xFAF7B910, 2190656) = 0
/65:    fstat64(9, 0xFAF7B818)                          = 0
/65:    getsockopt(9, 65535, 8192, 0xFAF7B918, 0xFAF7B914, 2190656) = 0
/65:    setsockopt(9, 65535, 8192, 0xFAF7B918, 4, 2190656) = 0
/65:    fcntl(9, F_SETFL, 0x00000082)                   = 0</pre></div>

    <p>Next, the worker thread puts the connection to the client (file
    descriptor 9) in non-blocking mode. The <code>setsockopt(2)</code>
    and <code>getsockopt(2)</code> calls are a side-effect of how
    Solaris' libc handles <code>fcntl(2)</code> on sockets.</p>

    <div class="example"><pre>/65:    read(9, " G E T   / 1 0 k . h t m".., 8000)     = 97</pre></div>

    <p>The worker thread reads the request from the client.</p>

    <div class="example"><pre>/65:    stat("/var/httpd/apache/httpd-8999/htdocs/10k.html", 0xFAF7B978) = 0
/65:    open("/var/httpd/apache/httpd-8999/htdocs/10k.html", O_RDONLY) = 10</pre></div>

    <p>This httpd has been configured with <code>Options FollowSymLinks</code>
    and <code>AllowOverride None</code>.  Thus it doesn't need to
    <code>lstat(2)</code> each directory in the path leading up to the
    requested file, nor check for <code>.htaccess</code> files.
    It simply calls <code>stat(2)</code> to verify that the file:
    1) exists, and 2) is a regular file, not a directory.</p>

    <div class="example"><pre>/65:    sendfilev(0, 9, 0x00200F90, 2, 0xFAF7B53C)      = 10269</pre></div>

    <p>In this example, the httpd is able to send the HTTP response
    header and the requested file with a single <code>sendfilev(2)</code>
    system call. Sendfile semantics vary among operating systems. On some other
    systems, it is necessary to do a <code>write(2)</code> or
    <code>writev(2)</code> call to send the headers before calling
    <code>sendfile(2)</code>.</p>

    <div class="example"><pre>/65:    write(4, " 1 2 7 . 0 . 0 . 1   -  ".., 78)      = 78</pre></div>

    <p>This <code>write(2)</code> call records the request in the
    access log. Note that one thing missing from this trace is a
    <code>time(2)</code> call. Unlike Apache 1.3, Apache 2.x uses
    <code>gettimeofday(3)</code> to look up the time. On some operating
    systems, like Linux or Solaris, <code>gettimeofday</code> has an
    optimized implementation that doesn't require as much overhead
    as a typical system call.</p>

    <div class="example"><pre>/65:    shutdown(9, 1, 1)                               = 0
/65:    poll(0xFAF7B980, 1, 2000)                       = 1
/65:    read(9, 0xFAF7BC20, 512)                        = 0
/65:    close(9)                                        = 0</pre></div>

    <p>The worker thread does a lingering close of the connection.</p>

    <div class="example"><pre>/65:    close(10)                                       = 0
/65:    lwp_park(0x00000000, 0)         (sleeping...)</pre></div>

    <p>Finally the worker thread closes the file that it has just delivered
    and blocks until the listener assigns it another connection.</p>

    <div class="example"><pre>/67:    accept(3, 0x001FEB74, 0x001FEB94, 1) (sleeping...)</pre></div>

    <p>Meanwhile, the listener thread is able to accept another connection
    as soon as it has dispatched this connection to a worker thread (subject
    to some flow-control logic in the worker MPM that throttles the listener
    if all the available workers are busy).  Though it isn't apparent from
    this trace, the next <code>accept(2)</code> can (and usually does, under
    high load conditions) occur in parallel with the worker thread's handling
    of the just-accepted connection.</p>

    <p>Apache 2.x est un serveur web à usage général, conçu dans un but
    d'équilibre entre souplesse, portabilité et performances. Bien que non
    conçu dans le seul but d'établir une référence en la matière,
    Apache 2.x est capable de hautes performances dans de nombreuses situations
    du monde réel.</p>

    <p>Comparée à Apache 1.3, la version 2.x comporte de nombreuses
    optimisations supplémentaires permettant d'améliorer le débit du serveur
    et sa personnalisation. La plupart de ces améliorations sont activées par
    défaut. Cependant, certains choix de configuration à la compilation et à
    l'exécution peuvent affecter les performances de manière significative. Ce
    document décrit les options qu'un administrateur de serveur peut configurer
    pour améliorer les performances d'une installation d'Apache 2.x. Certaines
    de ces options de configuration permettent au démon httpd de mieux tirer
    parti des possibilités du matériel et du système d'exploitation, tandis
    que d'autres permettent à l'administrateur de privilégier la vitesse
    par rapport aux fonctionnalités.</p>

<h2><a name="hardware" id="hardware">Problèmes matériels et relatifs au système d'exploitation</a></h2>

    

    <p>Le principal problème matériel qui affecte les performances du serveur
    web est la mémoire vive (RAM). Un serveur web ne devrait jamais avoir à
    utiliser le swap, car le swapping augmente le temps de réponse de chaque
    requête au delà du point que les utilisateurs considèrent comme
    "trop lent". Ceci incite les utilisateurs à cliquer sur "Stop", puis
    "Charger à nouveau", ce qui a pour effet d'augmenter encore la charge
    du serveur. Vous pouvez, et même devez définir la valeur de la directive
    <code class="directive"><a href="../mod/mpm_common.html#maxrequestworkers">MaxRequestWorkers</a></code> de façon à ce que
    votre serveur ne lance pas un nombre de processus enfants tel qu'il
    commence à faire du swapping. La méthode pour y parvenir est
    simple : déterminez la taille de votre processus Apache standard en
    consultant votre liste de processus à l'aide d'un outil tel que
    <code>top</code>, et divisez votre quantité totale de mémoire disponible
    par cette taille, tout en gardant un espace suffisant
    pour les autres processus.</p>

    <p>Hormis ce réglage relatif à la mémoire, le reste est trivial : le
    processeur, la carte réseau et les disques doivent être suffisamment
    rapides, où "suffisamment rapide" doit être déterminé par
    l'expérience.</p>

    <p>Le choix du système d'exploitation dépend principalement du
    contexte local. Voici cependant quelques conseils qui se sont
    généralement avérés utiles :</p>

    <ul>
      <li>
        <p>Exécutez la dernière version stable et le niveau de patches le
	plus haut du système d'exploitation que vous avez choisi. De nombreux
	éditeurs de systèmes d'exploitation ont amélioré de manière
	significative les performances de leurs piles TCP et de leurs
	bibliothèques de thread ces dernières années.</p>
      </li>

      <li>
        <p>Si votre système d'exploitation possède un appel système
	<code>sendfile(2)</code>, assurez-vous d'avoir installé la version
	et/ou les patches nécessaires à son activation. (Pour Linux, par
	exemple, cela se traduit par Linux 2.4 ou plus. Pour les versions
	anciennes de Solaris 8, vous pouvez être amené à appliquer un patch.)
	Sur les systèmes où il est disponible, <code>sendfile</code> permet
	à Apache 2 de servir les contenus statiques plus rapidement, tout en
	induisant une charge CPU inférieure.</p>
      </li>
    </ul>

    <h3><a name="dns" id="dns">HostnameLookups et autres considérations à propos du DNS</a></h3>

      

      <p>Avant Apache 1.3, la directive
      <code class="directive"><a href="../mod/core.html#hostnamelookups">HostnameLookups</a></code> était positionnée
      par défaut à <code>On</code>. Ce réglage augmente le temps de réponse de
      chaque requête car il entraîne une recherche DNS et le traitement de la
      requête ne pourra pas être achevé tant que cette recherche ne sera
      pas terminée. Avec Apache 1.3, ce réglage est défini par défaut à
      <code>Off</code>. Si vous souhaitez que les adresses dans vos fichiers
      journaux soient résolues en noms d'hôtes, utilisez le programme
      <code class="program"><a href="../programs/logresolve.html">logresolve</a></code> fourni avec Apache, ou un des nombreux
      paquets générateurs de rapports sur les journaux disponibles.</p>

      <p>Il est recommandé d'effectuer ce genre de traitement a posteriori
      de vos fichiers journaux sur une autre machine que celle qui héberge le
      serveur web en production, afin que cette activité n'affecte pas les
      performances du serveur.</p>

      <p>Si vous utilisez une directive
      <code><code class="directive"><a href="../mod/mod_access_compat.html#allow">Allow</a></code>from domain</code>
      ou
      <code><code class="directive"><a href="../mod/mod_access_compat.html#deny">Deny</a></code> from domain</code>
      (ce qui signifie que vous utilisez un nom d'hôte ou un nom de domaine à
      la place d'une adresse IP), vous devrez compter avec deux recherches
      DNS (une recherche inverse suivie d'une recherche directe pour
      s'assurer que l'adresse IP n'a pas été usurpée). C'est pourquoi il est
      préférable, pour améliorer les performances, d'utiliser des adresses IP
      plutôt que des noms lorsqu'on utilise ces directives, du moins chaque
      fois que c'est possible.</p>

      <p>Notez qu'il est possible de modifier la portée des directives, en les
      plaçant par exemple à l'intérieur d'une section
      <code>&lt;Location "/server-status"&gt;</code>. Les recherches DNS ne
      seront alors effectuées que pour les requêtes qui satisfont aux critères.
      Voici un exemple qui désactive les recherches DNS sauf pour les fichiers
      <code>.html</code> et <code>.cgi</code> :</p>

      <pre class="prettyprint lang-config">HostnameLookups off
&lt;Files ~ "\.(html|cgi)$"&gt;
  HostnameLookups on
&lt;/Files&gt;</pre>


      <p>Mais même dans ce cas, si vous n'avez besoin de noms DNS que dans
      certains CGIs, vous pouvez effectuer l'appel à <code>gethostbyname</code>
      dans les CGIs spécifiques qui en ont besoin.</p>

    

    <h3><a name="symlinks" id="symlinks">FollowSymLinks et SymLinksIfOwnerMatch</a></h3>

      

      <p>Chaque fois que la ligne <code>Options FollowSymLinks</code> sera
      absente, ou que la ligne <code>Options SymLinksIfOwnerMatch</code> sera
      présente dans votre espace d'adressage, Apache devra effectuer des
      appels système supplémentaires pour vérifier la présence de liens
      symboliques. Un appel supplémentaire par élément du chemin du fichier.
      Par exemple, si vous avez :</p>

      <pre class="prettyprint lang-config">DocumentRoot "/www/htdocs"
&lt;Directory "/"&gt;
  Options SymLinksIfOwnerMatch
&lt;/Directory&gt;</pre>


      <p>et si une requête demande l'URI <code>/index.html</code>, Apache
      effectuera un appel à <code>lstat(2)</code> pour
      <code>/www</code>, <code>/www/htdocs</code>, et
      <code>/www/htdocs/index.html</code>. Les résultats de ces appels à
      <code>lstat</code> ne sont jamais mis en cache, ils devront donc être
      générés à nouveau pour chaque nouvelle requête. Si vous voulez absolument
      vérifier la sécurité des liens symboliques, vous pouvez utiliser une
      configuration du style :</p>

      <pre class="prettyprint lang-config">DocumentRoot "/www/htdocs"
&lt;Directory "/"&gt;
  Options FollowSymLinks
&lt;/Directory&gt;

&lt;Directory "/www/htdocs"&gt;
  Options -FollowSymLinks +SymLinksIfOwnerMatch
&lt;/Directory&gt;</pre>


      <p>Ceci évite au moins les vérifications supplémentaires pour le chemin
      défini par <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>. Notez que
      vous devrez ajouter des sections similaires si vous avez des chemins
      définis par les directives
      <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code> ou
      <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> en dehors de
      la racine de vos documents. Pour améliorer les performances, et supprimer
      toute protection des liens symboliques, ajoutez l'option
      <code>FollowSymLinks</code> partout, et n'utilisez jamais l'option
      <code>SymLinksIfOwnerMatch</code>.</p>

    

    <h3><a name="htaccess" id="htaccess">AllowOverride</a></h3>

      

      <p>Dans toute partie de votre espace d'adressage où vous autoriserez
      la surcharge de la configuration (en général à l'aide de fichiers
      <code>.htaccess</code>), Apache va tenter d'ouvrir <code>.htaccess</code>
      pour chaque élément du chemin du fichier demandé. Par exemple, si vous
      avez : </p>

      <pre class="prettyprint lang-config">DocumentRoot "/www/htdocs"
&lt;Directory "/"&gt;
  AllowOverride all
&lt;/Directory&gt;</pre>


      <p>et qu'une requête demande l'URI <code>/index.html</code>, Apache
      tentera d'ouvrir <code>/.htaccess</code>, <code>/www/.htaccess</code>,
      et <code>/www/htdocs/.htaccess</code>. Les solutions sont similaires à
      celles évoquées précédemment pour <code>Options FollowSymLinks</code>.
      Pour améliorer les performances, utilisez <code>AllowOverride None</code>
      pour tous les niveaux de votre espace d'adressage.</p>

    

    <h3><a name="negotiation" id="negotiation">Négociation</a></h3>

      

      <p>Dans la mesure du possible, évitez toute négociation de contenu si
      vous tenez au moindre gain en performances. En pratique toutefois,
      les bénéfices de la négociation l'emportent souvent sur la diminution
      des performances.
      Il y a cependant un cas dans lequel vous pouvez accélérer le serveur.
      Au lieu d'utiliser une directive générique comme :</p>

      <pre class="prettyprint lang-config">DirectoryIndex index</pre>


      <p>utilisez une liste explicite d'options :</p>

      <pre class="prettyprint lang-config">DirectoryIndex index.cgi index.pl index.shtml index.html</pre>


      <p>où vous placez le choix courant en première position.</p>

      <p>Notez aussi que créer explicitement un fichier de
      <code>correspondances de type</code> fournit de meilleures performances
      que l'utilisation des <code>MultiViews</code>, car les informations
      nécessaires peuvent être simplement obtenues en lisant ce fichier, sans
      avoir à parcourir le répertoire à la recherche de types de fichiers.</p>

    <p>Par conséquent, si la négociation de contenu est nécessaire pour votre
    site, préférez les fichiers de <code>correspondances de type</code> aux
    directives <code>Options MultiViews</code> pour mener à bien cette
    négociation. Se référer au document sur la
    <a href="../content-negotiation.html">Négociation de contenu</a> pour une
    description complète des méthodes de négociation, et les instructions
    permettant de créer des fichiers de <code>correspondances de type</code>.</p>

    

    <h3>Transfert en mémoire</h3>

      

      <p>Dans les situations où Apache 2.x doit consulter le contenu d'un
      fichier en train d'être servi - par exemple à l'occasion du traitement
      d'une inclusion côté serveur - il transfère en général le fichier en
      mémoire si le système d'exploitation supporte une forme quelconque
      de <code>mmap(2)</code>.</p>

      <p>Sur certains systèmes, ce transfert en mémoire améliore les
      performances. Dans certains cas, ce transfert peut toutefois les dégrader
      et même diminuer la stabilité du démon httpd :</p>

      <ul>
        <li>
          <p>Dans certains systèmes d'exploitation, <code>mmap</code> devient
	  moins efficace que <code>read(2)</code> quand le nombre de
	  processeurs augmente. Sur les serveurs multiprocesseurs sous Solaris,
	  par exemple, Apache 2.x sert parfois les fichiers consultés par le
	  serveur plus rapidement quand <code>mmap</code> est désactivé.</p>
        </li>

        <li>
          <p>Si vous transférez en mémoire un fichier localisé dans un système
	  de fichiers monté par NFS, et si un processus sur
	  une autre machine cliente NFS supprime ou tronque le fichier, votre
	  processus peut rencontrer une erreur de bus la prochaine fois qu'il
	  essaiera d'accéder au contenu du fichier en mémoire.</p>
        </li>
      </ul>

      <p>Pour les installations où une de ces situations peut se produire,
      vous devez utiliser <code>EnableMMAP off</code> afin de désactiver le
      transfert en mémoire des fichiers servis. (Note : il est possible de
      passer outre cette directive au niveau de chaque répertoire.)</p>

    

    <h3>Sendfile</h3>

      

      <p>Dans les cas où Apache peut se permettre d'ignorer le contenu du
      fichier à servir - par exemple, lorsqu'il sert un contenu de fichier
      statique - il utilise en général le support sendfile du noyau si le
      système d'exploitation supporte l'opération <code>sendfile(2)</code>.</p>

      <p>Sur la plupart des plateformes, l'utilisation de sendfile améliore
      les performances en éliminant les mécanismes de lecture et envoi séparés.
      Dans certains cas cependant, l'utilisation de sendfile peut nuire à la
      stabilité du démon httpd :</p>

      <ul>
        <li>
          <p>Certaines plateformes peuvent présenter un support de sendfile
	  défaillant que la construction du système n'a pas détecté, en
	  particulier si les binaires ont été construits sur une autre machine
	  et transférés sur la machine où le support de sendfile est
	  défaillant.</p>
        </li>
        <li>
          <p>Dans le cas d'un système de fichiers monté
	  sous NFS, le noyau peut s'avérer incapable de servir
	  les fichiers réseau de manière fiable depuis
	  son propre cache.</p>
        </li>
      </ul>

      <p>Pour les installations où une de ces situations peut se produire,
      vous devez utiliser <code>EnableSendfile off</code> afin de désactiver
      la mise à disposition de contenus de fichiers par sendfile. (Note : il
      est possible de passer outre cette directive au niveau de chaque
      répertoire.)</p>

    

    <h3><a name="process" id="process">Process Creation</a></h3>

      

      <p>Avant Apache 1.3, les directives
      <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>,
      <code class="directive"><a href="../mod/prefork.html#maxspareservers">MaxSpareServers</a></code>, et
      <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code> avaient des
      effets drastiques sur les performances de référence. En particulier,
      Apache avait besoin d'un délai de "montée en puissance" afin d'atteindre
      un nombre de processus enfants suffisant pour supporter la charge qui lui
      était appliquée. Après le lancement initial des processus enfants par
      <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code>, seulement un
      processus enfant par seconde était créé afin d'atteindre la valeur de la
      directive <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>. Ainsi,
      un serveur accédé par 100 clients simultanés et utilisant la valeur par
      défaut de <code>5</code> pour la directive
      <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code>, nécessitait
      environ 95 secondes pour lancer suffisamment de processus enfants
      permettant de faire face à la charge. Ceci fonctionne en pratique pour
      les serveurs en production, car ils sont rarement redémarrés. Ce n'est
      cependant pas le cas pour les tests de référence (benchmarks) où le
      serveur ne fonctionne que 10 minutes.</p>

      <p>La règle "un processus par seconde" avait été implémentée afin
      d'éviter l'enlisement de la machine dans le démarrage de nouveaux
      processus enfants. Pendant que la machine est occupée à lancer des
      processus enfants, elle ne peut pas traiter les requêtes. Mais cette
      règle impactait tellement la perception des performances d'Apache qu'elle
      a dû être remplacée. A partir d'Apache 1.3, le code a assoupli la règle
      "un processus par seconde". Il va en lancer un, attendre une seconde,
      puis en lancer deux, attendre une seconde, puis en lancer quatre et
      ainsi de suite jusqu'à lancer 32 processus. Il s'arrêtera lorsque le
      nombre de processus aura atteint la valeur définie par la directive
      <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>.</p>

      <p>Ceci s'avère suffisamment réactif pour pouvoir en général se passer
      de manipuler les valeurs des directives
      <code class="directive"><a href="../mod/prefork.html#minspareservers">MinSpareServers</a></code>,
      <code class="directive"><a href="../mod/prefork.html#maxspareservers">MaxSpareServers</a></code> et
      <code class="directive"><a href="../mod/mpm_common.html#startservers">StartServers</a></code>. Lorsque plus de
      4 processus enfants sont lancés par seconde, un message est émis vers
      le journal des erreurs. Si vous voyez apparaître souvent ce genre de
      message, vous devez vous pencher sur ces réglages. Pour vous guider,
      utilisez les informations délivrées par le module
      <code class="module"><a href="../mod/mod_status.html">mod_status</a></code>.</p>

    <p>À mettre en relation avec la création de processus, leur destruction
    est définie par la valeur de la directive
    <code class="directive"><a href="../mod/mpm_common.html#maxconnectionsperchild">MaxConnectionsPerChild</a></code>. Sa valeur
    par défaut est <code>0</code>, ce qui signifie qu'il n'y a pas de limite
    au nombre de connexions qu'un processus enfant peut traiter. Si votre
    configuration actuelle a cette directive réglée à une valeur très basse,
    de l'ordre de <code>30</code>, il est conseillé de l'augmenter de manière
    significative. Si vous utilisez SunOs ou une ancienne version de Solaris,
    utilisez une valeur de l'ordre de <code>10000</code>  à cause des fuites
    de mémoire.</p>

    <p>Lorsqu'ils sont en mode "keep-alive", les processus enfants sont
    maintenus et ne font rien sinon attendre la prochaine requête sur la
    connexion déjà ouverte. La valeur par défaut de <code>5</code> de la
    directive <code class="directive"><a href="../mod/core.html#keepalivetimeout">KeepAliveTimeout</a></code> tend à
    minimiser cet effet. Il faut trouver le bon compromis entre la bande
    passante réseau et les ressources du serveur. En aucun cas vous ne devez
    choisir une valeur supérieure à <code>60</code> seconds, car
    <a href="http://www.hpl.hp.com/techreports/Compaq-DEC/WRL-95-4.html">
    la plupart des bénéfices sont alors perdus</a>.</p>

    <h3>Choisir un Module Multi-Processus (MPM)</h3>

      

      <p>Apache 2.x supporte les modèles simultanés enfichables, appelés
      <a href="../mpm.html">Modules Multi-Processus</a> (MPMs). Vous devez
      choisir un MPM au moment de la construction d'Apache. Certaines
      plateformes ont des modules MPM spécifiques :
      <code class="module"><a href="../mod/mpm_netware.html">mpm_netware</a></code>, <code class="module"><a href="../mod/mpmt_os2.html">mpmt_os2</a></code> et
      <code class="module"><a href="../mod/mpm_winnt.html">mpm_winnt</a></code>. Sur les systèmes de type Unix, vous avez le
      choix entre un grand nombre de modules MPM. Le choix du MPM peut affecter
      la vitesse et l'évolutivité du démon httpd :</p>

      <ul>

        <li>Le MPM <code class="module"><a href="../mod/worker.html">worker</a></code> utilise plusieurs processus
	enfants possédant chacun de nombreux threads. Chaque thread gère une
	seule connexion à la fois. Worker est en général un bon choix pour les
	serveurs présentant un traffic important car il possède une empreinte
	mémoire plus petite que le MPM prefork.</li>

	<li>Comme le MPM Worker, le MPM <code class="module"><a href="../mod/event.html">event</a></code> utilise
	les threads, mais il a été conçu pour traiter davantage de
	requêtes simultanément en confiant une partie du travail à des
	threads de support, ce qui permet aux threads principaux de
	traiter de nouvelles requêtes.</li>

        <li>Le MPM <code class="module"><a href="../mod/prefork.html">prefork</a></code> utilise plusieurs processus enfants
	possédant chacun un seul thread. Chaque processus gère une seule
	connexion à la fois. Sur de nombreux systèmes, prefork est comparable
	en matière de vitesse à worker, mais il utilise plus de mémoire. De par
	sa conception sans thread, prefork présente des avantages par rapport à
	worker dans certaines situations : il peut être utilisé avec les
	modules tiers qui ne supportent pas le threading, et son débogage est plus
	aisé sur les platesformes présentant un support du débogage des threads
	rudimentaire.</li>

      </ul>

      <p>Pour plus d'informations sur ces deux MPMs et les autres, veuillez
      vous référer à la <a href="../mpm.html">documentation sur les
      MPM</a>.</p>

    

    <h3><a name="modules" id="modules">Modules</a></h3>

        

        <p>Comme le contrôle de l'utilisation de la mémoire est très important
	en matière de performance, il est conseillé d'éliminer les modules que
	vous n'utilisez pas vraiment. Si vous avez construit ces modules en
	tant que <a href="../dso.html">DSOs</a>, leur élimination consiste
	simplement à commenter la directive
	<code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> associée à ce
	module. Ceci vous permet de vérifier si votre site fonctionne toujours
	après la suppression de tel ou tel module.</p>

        <p>Par contre, si les modules que vous voulez supprimer sont liés
	statiquement à votre binaire Apache, vous devrez recompiler ce dernier
	afin de pouvoir les éliminer.</p>

        <p>La question qui découle de ce qui précède est évidemment de
	savoir de quels modules vous avez besoin et desquels vous pouvez vous
	passer. La réponse sera bien entendu différente d'un site web à
	l'autre. Cependant, la liste <em>minimale</em> de modules nécessaire à
	la survie de votre site contiendra certainement
	<code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code>, <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> et
	<code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>. <code>mod_log_config</code> est bien
	entendu optionnel puisque vous pouvez faire fonctionner un site web
	en se passant de fichiers journaux ; ceci est cependant
	déconseillé.</p>

    

    <h3>Opérations atomiques</h3>

      

      <p>Certains modules, à l'instar de <code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code> et des
      versions de développement récentes du MPM worker, utilisent l'API
      atomique d'APR. Cette API propose des opérations atomiques que l'on
      peut utiliser pour alléger la synchronisation des threads.</p>

      <p>Par défaut, APR implémente ces opérations en utilisant les
      mécanismes les plus efficaces disponibles sur chaque plateforme cible
      (Système d'exploitation et processeur). De nombreux processeurs modernes,
      par exemple, possèdent une instruction qui effectue une opération
      atomique de type comparaison et échange ou compare-and-swap (CAS) au
      niveau matériel. Sur certaines platesformes cependant, APR utilise par
      défaut une implémentation de l'API atomique plus lente, basée sur les
      mutex, afin d'assurer la compatibilité avec les anciens modèles de
      processeurs qui ne possèdent pas ce genre d'instruction. Si vous
      construisez Apache pour une de ces platesformes, et ne prévoyez de
      l'exécuter que sur des processeurs récents, vous pouvez sélectionner une
      implémentation atomique plus rapide à la compilation en utilisant
      l'option <code>--enable-nonportable-atomics</code> du
      script configure :</p>

      <div class="example"><p><code>
        ./buildconf<br />
        ./configure --with-mpm=worker --enable-nonportable-atomics=yes
      </code></p></div>

      <p>L'option <code>--enable-nonportable-atomics</code> concerne les
      platesformes suivantes :</p>

      <ul>

        <li>Solaris sur SPARC<br />
            Sur Solaris/SPARC, APR utilise par défaut les opérations
	    atomiques basées sur les mutex. Cependant, si vous ajoutez l'option
	    <code>--enable-nonportable-atomics</code> au script configure, APR
	    génère un code qui utilise le code opération SPARC v8plus pour des
	    opérations de compare-and-swap matériel plus rapides. Si vous
	    utilisez cette option de configure avec Apache, les opérations
	    atomiques seront plus efficaces (permettant d'alléger la charge du
	    processeur et un plus haut niveau de simultanéité), mais
	    l'exécutable produit ne fonctionnera que sur les processeurs
	    UltraSPARC.
	</li>

        <li>Linux sur x86<br />
            Sous Linux, APR utilise par défaut les opérations atomiques basées
	    sur les mutex. Cependant, si vous ajoutez l'option
	    <code>--enable-nonportable-atomics</code> au script configure,
	    APR générera un code qui utilise un code d'opération du 486
	    pour des opérations de compare-and-swap matériel plus rapides. Le
	    code résultant est plus efficace en matière d'opérations atomiques,
	    mais l'exécutable produit ne fonctionnera que sur des processeurs
	    486 et supérieurs (et non sur des 386).
        </li>

      </ul>

    

    <h3>Module mod_status et ExtendedStatus On</h3>

      

      <p>Si vous incluez le module <code class="module"><a href="../mod/mod_status.html">mod_status</a></code> à la
      construction d'Apache et ajoutez <code>ExtendedStatus On</code> à sa
      configuration, Apache va effectuer pour chaque requête deux appels à
      <code>gettimeofday(2)</code> (ou <code>times(2)</code> selon votre
      système d'exploitation), et (pour les versions antérieures à 1.3) de
      nombreux appels supplémentaires à <code>time(2)</code>. Tous ces
      appels sont effectués afin que le rapport de statut puisse contenir
      des indications temporelles. Pour améliorer les performances, utilisez
      <code>ExtendedStatus off</code> (qui est le réglage par défaut).</p>

    

    <h3>accept Serialization - points de connexion à un programme (sockets) multiples</h3>

      

    <div class="warning"><h3>Mise en garde :</h3>
      <p>Cette section n'a pas été totalement mise à jour car elle ne tient pas
      compte des changements intervenus dans la version 2.x du Serveur HTTP
      Apache. Certaines informations sont encore pertinentes, il vous est
      cependant conseillé de les utiliser avec prudence.</p>
    </div>

      <p>Ce qui suit est une brève discussion à propos de l'API des sockets
      Unix. Supposons que votre serveur web utilise plusieurs directives
      <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> afin d'écouter
      plusieurs ports ou de multiples adresses. Afin de tester chaque socket
      pour voir s'il a une connexion en attente, Apache utilise
      <code>select(2)</code>. <code>select(2)</code> indique si un socket a
      <em>zéro</em> ou <em>au moins une</em> connexion en attente. Le modèle
      d'Apache comporte plusieurs processus enfants, et tous ceux qui sont
      inactifs testent la présence de nouvelles connexions au même moment.
      Une implémentation rudimentaire de ceci pourrait ressembler à
      l'exemple suivant
      (ces exemples ne sont pas extraits du code d'Apache, ils ne sont
      proposés qu'à des fins pédagogiques) :</p>

      <pre class="prettyprint lang-c">        for (;;) {
          for (;;) {
            fd_set accept_fds;

            FD_ZERO (&amp;accept_fds);
            for (i = first_socket; i &lt;= last_socket; ++i) {
              FD_SET (i, &amp;accept_fds);
            }
            rc = select (last_socket+1, &amp;accept_fds, NULL, NULL, NULL);
            if (rc &lt; 1) continue;
            new_connection = -1;
            for (i = first_socket; i &lt;= last_socket; ++i) {
              if (FD_ISSET (i, &amp;accept_fds)) {
                new_connection = accept (i, NULL, NULL);
                if (new_connection != -1) break;
              }
            }
            if (new_connection != -1) break;
          }
          process_the(new_connection);
        }</pre>


      <p>Mais cette implémentation rudimentaire présente une sérieuse lacune.
      Rappelez-vous que les processus enfants exécutent cette boucle au même
      moment ; ils vont ainsi bloquer sur <code>select</code> s'ils se trouvent
      entre deux requêtes. Tous ces processus bloqués vont se réactiver et
      sortir de <code>select</code> quand une requête va apparaître sur un des
      sockets (le nombre de processus enfants qui se réactivent varie en
      fonction du système d'exploitation et des réglages de synchronisation).
      Ils vont alors tous entrer dans la boucle et tenter un
      <code>"accept"</code> de la connexion. Mais seulement un d'entre eux y
      parviendra (en supposant qu'il ne reste q'une seule connexion en
      attente), les autres vont se bloquer au niveau de <code>accept</code>.
      Ceci verrouille vraiment ces processus de telle sorte qu'ils ne peuvent
      plus servir de requêtes que par cet unique socket, et il en sera ainsi
      jusqu'à ce que suffisamment de nouvelles requêtes apparaissent sur ce
      socket pour les réactiver tous. Cette lacune a été documentée pour la
      première fois dans
      <a href="http://bugs.apache.org/index/full/467">PR#467</a>. Il existe
      au moins deux solutions.</p>

      <p>La première consiste à rendre les sockets non blocants. Dans ce cas,
      <code>accept</code> ne bloquera pas les processus enfants, et ils
      pourront continuer à s'exécuter immédiatement. Mais ceci consomme des
      ressources processeur. Supposons que vous ayez dix processus enfants
      inactifs dans <code>select</code>, et qu'une connexion arrive.
      Neuf des dix processus vont se réactiver, tenter un <code>accept</code>
      de la connexion, échouer, et boucler dans <code>select</code>, tout en
      n'ayant finalement rien accompli. Pendant ce temps, aucun de ces processus
      ne traite les requêtes qui arrivent sur d'autres sockets jusqu'à ce
      qu'ils retournent dans <code>select</code>. Finalement, cette solution
      ne semble pas très efficace, à moins que vous ne disposiez d'autant de
      processeurs inactifs (dans un serveur multiprocesseur) que de processus
      enfants inactifs, ce qui n'est pas une situation très courante.</p>

      <p>Une autre solution, celle qu'utilise Apache, consiste à sérialiser les
      entrées dans la boucle interne. La boucle ressemble à ceci (les
      différences sont mises en surbrillance) :</p>

      <pre class="prettyprint lang-c">        for (;;) {
          <strong>accept_mutex_on ();</strong>
          for (;;) {
            fd_set accept_fds;
            
            FD_ZERO (&amp;accept_fds);
            for (i = first_socket; i &lt;= last_socket; ++i) {
              FD_SET (i, &amp;accept_fds);
            }
            rc = select (last_socket+1, &amp;accept_fds, NULL, NULL, NULL);
            if (rc &lt; 1) continue;
            new_connection = -1;
            for (i = first_socket; i &lt;= last_socket; ++i) {
              if (FD_ISSET (i, &amp;accept_fds)) {
                new_connection = accept (i, NULL, NULL);
                if (new_connection != -1) break;
              }
            }
            if (new_connection != -1) break;
          }
          <strong>accept_mutex_off ();</strong>
          process the new_connection;
        }</pre>


      <p><a id="serialize" name="serialize">Les fonctions</a>
      <code>accept_mutex_on</code> et <code>accept_mutex_off</code>
      implémentent un sémaphore permettant une exclusion mutuelle. Un seul
      processus enfant à la fois peut posséder le mutex. Plusieurs choix se
      présentent pour implémenter ces mutex. Ce choix est défini dans
      <code>src/conf.h</code> (versions antérieures à 1.3) ou
      <code>src/include/ap_config.h</code> (versions 1.3 ou supérieures).
      Certaines architectures ne font pas ce choix du mode de verrouillage ;
      l'utilisation de directives
      <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> multiples sur ces
      architectures est donc peu sûr.</p>

      <p>La directive <code class="directive"><a href="../mod/core.html#mutex">Mutex</a></code> permet
      de modifier l'implémentation du mutex <code>mpm-accept</code> à
      l'exécution. Des considérations spécifiques aux différentes
      implémentations de mutex sont documentées avec cette directive.</p>

      <p>Une autre solution qui a été imaginée mais jamais implémentée, consiste
      à sérialiser partiellement la boucle -- c'est à dire y faire entrer un
      certain nombre de processus. Ceci ne présenterait un intérêt que sur les
      machines multiprocesseurs où plusieurs processus enfants peuvent
      s'exécuter simultanément, et encore, la sérialisation ne tire pas
      vraiment parti de toute la bande passante. C'est une possibilité
      d'investigation future, mais demeure de priorité basse car les serveurs
      web à architecture hautement parallèle ne sont pas la norme.</p>

      <p>Pour bien faire, vous devriez faire fonctionner votre serveur sans
      directives <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> multiples
      si vous visez les performances les plus élevées.
      Mais lisez ce qui suit.</p>

    

    <h3>accept Serialization - point de connexion à un programme (sockets) unique</h3>

      

      <p>Ce qui précède convient pour les serveurs à sockets multiples, mais
      qu'en est-il des serveurs à socket unique ? En théorie, ils ne
      devraient pas rencontrer les mêmes problèmes car tous les processus
      enfants peuvent se bloquer dans <code>accept(2)</code> jusqu'à ce qu'une
      connexion arrive, et ils ne sont pas utilisés à ne rien faire. En
      pratique, ceci dissimule un même comportement de bouclage
      discuté plus haut dans la solution non-blocante. De la manière dont
      sont implémentées les piles TCP, le noyau réactive véritablement tous les
      processus bloqués dans <code>accept</code> quand une seule connexion
      arrive. Un de ces processus prend la connexion en compte et retourne
      dans l'espace utilisateur, les autres bouclant dans l'espace du
      noyau et se désactivant quand ils s'aperçoivent qu'il n'y a pas de
      connexion pour eux. Ce bouclage est invisible depuis le code de l'espace
      utilisateur, mais il est quand-même présent. Ceci peut conduire à la
      même augmentation de charge à perte que la solution non blocante au cas
      des sockets multiples peut induire.</p>

      <p>Pour cette raison, il apparaît que de nombreuses architectures se
      comportent plus "proprement" si on sérialise même dans le cas d'une socket
      unique. Il s'agit en fait du comportement par défaut dans la plupart des
      cas. Des expériences poussées sous Linux (noyau 2.0.30 sur un
      biprocesseur Pentium pro 166 avec 128 Mo de RAM) ont montré que la
      sérialisation d'une socket unique provoque une diminution inférieure à 3%
      du nombre de requêtes par secondes par rapport au traitement non
      sérialisé. Mais le traitement non sérialisé des sockets uniques induit
      un temps de réponse supplémentaire de 100 ms pour chaque requête. Ce
      temps de réponse est probablement provoqué par une limitation sur les
      lignes à haute charge, et ne constitue un problème que sur les réseaux
      locaux. Si vous voulez vous passer de la sérialisation des sockets
      uniques, vous pouvez définir
      <code>SINGLE_LISTEN_UNSERIALIZED_ACCEPT</code> et les
      serveurs à socket unique ne pratiqueront plus du tout la
      sérialisation.</p>

    

    <h3>Fermeture en prenant son temps (Lingering close)</h3>

      

      <p>Comme discuté dans <a href="http://www.ics.uci.edu/pub/ietf/http/draft-ietf-http-connection-00.txt">
      draft-ietf-http-connection-00.txt</a> section 8, pour implémenter de
      manière <strong>fiable</strong> le protocole, un serveur HTTP doit fermer
      les deux directions d'une communication indépendamment (rappelez-vous
      qu'une connexion TCP est bidirectionnelle, chaque direction étant
      indépendante de l'autre).</p>

      <p>Quand cette fonctionnalité fut ajoutée à Apache, elle causa une
      avalanche de problèmes sur plusieurs versions d'Unix à cause d'une
      implémentation à courte vue. La spécification TCP ne précise pas que
      l'état <code>FIN_WAIT_2</code> possède un temps de réponse mais elle ne
      l'exclut pas. Sur les systèmes qui n'introduisent pas ce temps de
      réponse, Apache 1.2 induit de nombreux blocages définitifs de socket
      dans l'état <code>FIN_WAIT_2</code>. On peut eviter ceci dans de nombreux
      cas tout simplement en mettant à jour TCP/IP avec le dernier patch mis à
      disposition par le fournisseur. Dans les cas où le fournisseur n'a
      jamais fourni de patch (par exemple, SunOS4 -- bien que les utilisateurs
      possédant une license source puissent le patcher eux-mêmes), nous avons
      décidé de désactiver cette fonctionnalité.</p>

      <p>Il y a deux méthodes pour arriver à ce résultat. La première est
      l'option de socket <code>SO_LINGER</code>. Mais le sort a voulu que cette
      solution ne soit jamais implémentée correctement dans la plupart des
      piles TCP/IP. Et même dans les rares cas où cette solution a été
      implémentée correctement (par exemple Linux 2.0.31), elle se
      montre beaucoup plus gourmande (en temps processeur) que la solution
      suivante.</p>

      <p>Pour la plus grande partie, Apache implémente cette solution à l'aide
      d'une fonction appelée <code>lingering_close</code> (définie dans
      <code>http_main.c</code>). La fonction ressemble approximativement à
      ceci :</p>

      <pre class="prettyprint lang-c">        void lingering_close (int s)
        {
          char junk_buffer[2048];
          
          /* shutdown the sending side */
          shutdown (s, 1);

          signal (SIGALRM, lingering_death);
          alarm (30);

          for (;;) {
            select (s for reading, 2 second timeout);
            if (error) break;
            if (s is ready for reading) {
              if (read (s, junk_buffer, sizeof (junk_buffer)) &lt;= 0) {
                break;
              }
              /* just toss away whatever is here */
            }
          }
          
          close (s);
        }</pre>


      <p>Ceci ajoute naturellement un peu de charge à la fin d'une connexion,
      mais s'avère nécessaire pour une implémentation fiable. Comme HTTP/1.1
      est de plus en plus présent et que toutes les connexions sont
      persistentes, la charge sera amortie par la multiplicité des requêtes.
      Si vous voulez jouer avec le feu en désactivant cette fonctionnalité,
      vous pouvez définir <code>NO_LINGCLOSE</code>, mais c'est fortement
      déconseillé. En particulier, comme les connexions persistantes en
      pipeline de HTTP/1.1 commencent à être utilisées,
      <code>lingering_close</code> devient une absolue nécessité (et les
      <a href="http://www.w3.org/Protocols/HTTP/Performance/Pipeline.html">
      connexions en pipeline sont plus rapides</a> ; vous avez donc tout
      intérêt à les supporter).</p>

    

    <h3>Fichier tableau de bord (Scoreboard file)</h3>

      

      <p>Les processus parent et enfants d'Apache communiquent entre eux à
      l'aide d'un objet appelé "Tableau de bord" (Scoreboard). Idéalement, cet
      échange devrait s'effectuer en mémoire partagée. Pour les systèmes
      d'exploitation auxquels nous avons eu accès, ou pour lesquels nous avons
      obtenu des informations suffisamment détaillées pour effectuer un
      portage, cet échange est en général implémenté en utilisant la mémoire
      partagée. Pour les autres, on utilise par défaut un fichier d'échange sur
      disque. Le fichier d'échange sur disque est non seulement lent, mais
      aussi peu fiable (et propose moins de fonctionnalités). Recherchez dans
      le fichier <code>src/main/conf.h</code> correspondant à votre
      architecture soit <code>USE_MMAP_SCOREBOARD</code>, soit
      <code>USE_SHMGET_SCOREBOARD</code>. La définition de l'un des deux
      (ainsi que leurs compagnons respectifs <code>HAVE_MMAP</code> et
      <code>HAVE_SHMGET</code>), active le code fourni pour la mémoire
      partagée. Si votre système propose une autre solution pour la gestion de
      la mémoire partagée, éditez le fichier <code>src/main/http_main.c</code>
      et ajoutez la portion de code nécessaire pour pouvoir l'utiliser dans
      Apache (Merci de nous envoyer aussi le patch correspondant).</p>

      <div class="note">Note à caractère historique : le portage d'Apache sous Linux
      n'utilisait pas la mémoire partagée avant la version 1.2. Ceci entraînait
      un comportement très rudimentaire et peu fiable des versions antérieures
      d'Apache sous Linux.</div>

    

    <h3>DYNAMIC_MODULE_LIMIT</h3>

      

      <p>Si vous n'avez pas l'intention d'utiliser les modules chargés
      dynamiquement (ce qui est probablement le cas si vous êtes en train de
      lire ce document afin de personnaliser votre serveur en recherchant le
      moindre des gains en performances), vous pouvez ajouter la définition
      <code>-DDYNAMIC_MODULE_LIMIT=0</code> à la construction de votre serveur.
      Ceci aura pour effet de libérer la mémoire RAM allouée pour le
      chargement dynamique des modules.</p>

<div class="section">
<h2><a name="trace" id="trace">Appendice : Analyse détaillée d'une trace</a></h2>

    

    <p>Voici la trace d'un appel système d'Apache 2.0.38 avec le MPM worker
    sous Solaris 8. Cette trace a été collectée à l'aide de la commande :</p>

    <div class="example"><p><code>
      truss -l -p <var>httpd_child_pid</var>.
    </code></p></div>

    <p>L'option <code>-l</code> demande à truss de tracer l'ID du LWP
    (lightweight process--la version de Solaris des threads niveau noyau) qui
    invoque chaque appel système.</p>

    <p>Les autres systèmes peuvent proposer des utilitaires de traçage
    des appels système différents comme <code>strace</code>,
    <code>ktrace</code>, ou <code>par</code>. Ils produisent cependant tous une
    trace similaire.</p>

    <p>Dans cette trace, un client a demandé un fichier statique de 10 ko au
    démon httpd. Le traçage des requêtes pour des contenus non statiques
    ou comportant une négociation de contenu a une présentation
    différente (et même assez laide dans certains cas).</p>

    <div class="example"><pre>/67:    accept(3, 0x00200BEC, 0x00200C0C, 1) (sleeping...)
/67:    accept(3, 0x00200BEC, 0x00200C0C, 1)            = 9</pre></div>

    <p>Dans cette trace, le thread à l'écoute s'exécute à l'intérieur de
    LWP #67.</p>

    <div class="note">Notez l'absence de la sérialisation d'<code>accept(2)</code>. Sur
    cette plateforme spécifique, le MPM worker utilise un accept non sérialisé
    par défaut sauf s'il est en écoute sur des ports multiples.</div>

    <div class="example"><pre>/65:    lwp_park(0x00000000, 0)                         = 0
/67:    lwp_unpark(65, 1)                               = 0</pre></div>

    <p>Après avoir accepté la connexion, le thread à l'écoute réactive un
    thread du worker pour effectuer le traitement de la requête. Dans cette
    trace, le thread du worker qui traite la requête est associé à
    LWP #65.</p>

    <div class="example"><pre>/65:    getsockname(9, 0x00200BA4, 0x00200BC4, 1)       = 0</pre></div>

    <p>Afin de pouvoir implémenter les hôtes virtuels, Apache doit connaître
    l'adresse du socket local utilisé pour accepter la connexion. On pourrait
    supprimer cet appel dans de nombreuses situations (par exemple dans le cas
    où il n'y a pas d'hôte virtuel ou dans le cas où les directives
    <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code> contiennent des adresses
    sans caractères de substitution). Mais aucun effort n'a été accompli à ce
    jour pour effectuer ces optimisations.</p>

    <div class="example"><pre>/65:    brk(0x002170E8)                                 = 0
/65:    brk(0x002190E8)                                 = 0</pre></div>

    <p>L'appel <code>brk(2)</code> alloue de la mémoire dans le tas. Ceci est
    rarement visible dans une trace d'appel système, car le démon httpd
    utilise des allocateurs mémoire de son cru (<code>apr_pool</code> et
    <code>apr_bucket_alloc</code>) pour la plupart des traitements de requêtes.
    Dans cette trace, le démon httpd vient juste de démarrer, et il doit
    appeler <code>malloc(3)</code> pour réserver les blocs de mémoire
    nécessaires à la création de ses propres allocateurs de mémoire.</p>

    <div class="example"><pre>/65:    fcntl(9, F_GETFL, 0x00000000)                   = 2
/65:    fstat64(9, 0xFAF7B818)                          = 0
/65:    getsockopt(9, 65535, 8192, 0xFAF7B918, 0xFAF7B910, 2190656) = 0
/65:    fstat64(9, 0xFAF7B818)                          = 0
/65:    getsockopt(9, 65535, 8192, 0xFAF7B918, 0xFAF7B914, 2190656) = 0
/65:    setsockopt(9, 65535, 8192, 0xFAF7B918, 4, 2190656) = 0
/65:    fcntl(9, F_SETFL, 0x00000082)                   = 0</pre></div>

    <p>Ensuite, le thread de worker passe la connexion du client (descripteur
    de fichier 9) en mode non blocant. Les appels <code>setsockopt(2)</code>
    et <code>getsockopt(2)</code> constituent un effet de bord de la manière
    dont la libc de Solaris utilise <code>fcntl(2)</code> pour les sockets.</p>

    <div class="example"><pre>/65:    read(9, " G E T   / 1 0 k . h t m".., 8000)     = 97</pre></div>

    <p>Le thread de worker lit la requête du client.</p>

    <div class="example"><pre>/65:    stat("/var/httpd/apache/httpd-8999/htdocs/10k.html", 0xFAF7B978) = 0
/65:    open("/var/httpd/apache/httpd-8999/htdocs/10k.html", O_RDONLY) = 10</pre></div>

    <p>Ce démon httpd a été configuré avec les options
    <code>Options FollowSymLinks</code> et <code>AllowOverride None</code>. Il
    n'a donc ni besoin d'appeler <code>lstat(2)</code> pour chaque répertoire
    du chemin du fichier demandé, ni besoin de vérifier la présence de fichiers
    <code>.htaccess</code>. Il appelle simplement <code>stat(2)</code> pour
    vérifier d'une part que le fichier existe, et d'autre part que c'est un
    fichier régulier, et non un répertoire.</p>

    <div class="example"><pre>/65:    sendfilev(0, 9, 0x00200F90, 2, 0xFAF7B53C)      = 10269</pre></div>

    <p>Dans cet exemple, le démon httpd peut envoyer l'en-tête de la réponse
    HTTP et le fichier demandé à l'aide d'un seul appel système
    <code>sendfilev(2)</code>. La sémantique de sendfile varie en fonction des
    systèmes d'exploitation. Sur certains autres systèmes, il faut faire un
    appel à <code>write(2)</code> ou <code>writev(2)</code> pour envoyer les
    en-têtes avant d'appeler <code>sendfile(2)</code>.</p>

    <div class="example"><pre>/65:    write(4, " 1 2 7 . 0 . 0 . 1   -  ".., 78)      = 78</pre></div>

    <p>Cet appel à <code>write(2)</code> enregistre la requête dans le journal
    des accès. Notez qu'une des choses manquant à cette trace est un appel à
    <code>time(2)</code>. A la différence d'Apache 1.3, Apache 2.x utilise
    <code>gettimeofday(3)</code> pour consulter l'heure. Sur certains systèmes
    d'exploitation, comme Linux ou Solaris, <code>gettimeofday</code> est
    implémenté de manière optimisée de telle sorte qu'il consomme moins de
    ressources qu'un appel système habituel.</p>

    <div class="example"><pre>/65:    shutdown(9, 1, 1)                               = 0
/65:    poll(0xFAF7B980, 1, 2000)                       = 1
/65:    read(9, 0xFAF7BC20, 512)                        = 0
/65:    close(9)                                        = 0</pre></div>

    <p>Le thread de worker effectue une fermeture "en prenant son temps"
    (lingering close) de la connexion.</p>

    <div class="example"><pre>/65:    close(10)                                       = 0
/65:    lwp_park(0x00000000, 0)         (sleeping...)</pre></div>

    <p>Enfin, le thread de worker ferme le fichier qu'il vient de délivrer et
    se bloque jusqu'à ce que le thread en écoute lui assigne une autre
    connexion.</p>

    <div class="example"><pre>/67:    accept(3, 0x001FEB74, 0x001FEB94, 1) (sleeping...)</pre></div>

    <p>Pendant ce temps, le thread à l'écoute peut accepter une autre connexion
    à partir du moment où il a assigné la connexion présente à un thread de
    worker (selon une certaine logique de contrôle de flux dans le MPM worker
    qui impose des limites au thread à l'écoute si tous les threads de worker
    sont occupés). Bien que cela n'apparaisse pas dans cette trace,
    l'<code>accept(2)</code> suivant peut (et le fait en général, en situation
    de charge élevée) s'exécuter en parallèle avec le traitement de la
    connexion qui vient d'être acceptée par le thread de worker.</p>

.SH "SUMMARY"
 
.PP
\fBsuexec\fR is used by the Apache HTTP Server to switch to another user before executing CGI programs\&. In order to achieve this, it must run as \fBroot\fR\&. Since the HTTP daemon normally doesn't run as \fBroot\fR, the \fBsuexec\fR executable needs the setuid bit set and must be owned by \fBroot\fR\&. It should never be writable for any other person than \fBroot\fR\&.
 
.PP
For further information about the concepts and the security model of suexec please refer to the suexec documentation (http://httpd\&.apache\&.org/docs/2\&.4/suexec\&.html)\&.

.SH "SUMMARY"
 
.PP
\fBhtdbm\fR is used to manipulate the DBM format files used to store usernames and password for basic authentication of HTTP users via mod_authn_dbm\&. See the dbmmanage documentation for more information about these DBM files\&.
 

.SH "OPTIONS"
 
 
.TP
\fB-b\fR
Use batch mode; \fIi\&.e\&.\fR, get the password from the command line rather than prompting for it\&. This option should be used with extreme care, since \fBthe password is clearly visible\fR on the command line\&. For script use see the \fB-i\fR option\&.  
.TP
\fB-i\fR
Read the password from stdin without verification (for script usage)\&.  
.TP
\fB-c\fR
Create the \fIpasswdfile\fR\&. If \fIpasswdfile\fR already exists, it is rewritten and truncated\&. This option cannot be combined with the \fB-n\fR option\&.  
.TP
\fB-n\fR
Display the results on standard output rather than updating a database\&. This option changes the syntax of the command line, since the \fIpasswdfile\fR argument (usually the first one) is omitted\&. It cannot be combined with the \fB-c\fR option\&.  
.TP
\fB-m\fR
Use MD5 encryption for passwords\&. On Windows and Netware, this is the default\&.  
.TP
\fB-B\fR
Use bcrypt encryption for passwords\&. This is currently considered to be very secure\&.  
.TP
\fB-C\fR
This flag is only allowed in combination with \fB-B\fR (bcrypt encryption)\&. It sets the computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 31)\&.  
.TP
\fB-d\fR
Use \fBcrypt()\fR encryption for passwords\&. The default on all platforms but Windows and Netware\&. Though possibly supported by \fBhtdbm\fR on all platforms, it is not supported by the httpd server on Windows and Netware\&. This algorithm is \fBinsecure\fR by today's standards\&.  
.TP
\fB-s\fR
Use SHA encryption for passwords\&. Facilitates migration from/to Netscape servers using the LDAP Directory Interchange Format (ldif)\&. This algorithm is \fBinsecure\fR by today's standards\&.  
.TP
\fB-p\fR
Use plaintext passwords\&. Though \fBhtdbm\fR will support creation on all platforms, the httpd daemon will only accept plain text passwords on Windows and Netware\&.  
.TP
\fB-l\fR
Print each of the usernames and comments from the database on stdout\&.  
.TP
\fB-v\fR
Verify the username and password\&. The program will print a message indicating whether the supplied password is valid\&. If the password is invalid, the program exits with error code 3\&.  
.TP
\fB-x\fR
Delete user\&. If the username exists in the specified DBM file, it will be deleted\&.  
.TP
\fB-t\fR
Interpret the final parameter as a comment\&. When this option is specified, an additional string can be appended to the command line; this string will be stored in the "Comment" field of the database, associated with the specified username\&.  
.TP
\fB\fIfilename\fR\fR
The filename of the DBM format file\&. Usually without the extension \fB\&.db\fR, \fB\&.pag\fR, or \fB\&.dir\fR\&. If \fB-c\fR is given, the DBM file is created if it does not already exist, or updated if it does exist\&.  
.TP
\fB\fIusername\fR\fR
The username to create or update in \fIpasswdfile\fR\&. If \fIusername\fR does not exist in this file, an entry is added\&. If it does exist, the password is changed\&.  
.TP
\fB\fIpassword\fR\fR
The plaintext password to be encrypted and stored in the DBM file\&. Used only with the \fB-b\fR flag\&.  
.TP
\fB-T\fIDBTYPE\fR\fR
Type of DBM file (SDBM, GDBM, DB, or "default")\&.  
 
.SH "BUGS"
 
.PP
One should be aware that there are a number of different DBM file formats in existence, and with all likelihood, libraries for more than one format may exist on your system\&. The three primary examples are SDBM, NDBM, GNU GDBM, and Berkeley/Sleepycat DB 2/3/4\&. Unfortunately, all these libraries use different file formats, and you must make sure that the file format used by \fIfilename\fR is the same format that \fBhtdbm\fR expects to see\&. \fBhtdbm\fR currently has no way of determining what type of DBM file it is looking at\&. If used against the wrong format, will simply return nothing, or may create a different DBM file with a different name, or at worst, it may corrupt the DBM file if you were attempting to write to it\&.
 
.PP
One can usually use the \fBfile\fR program supplied with most Unix systems to see what format a DBM file is in\&.
 
.SH "EXIT STATUS"
 
.PP
\fBhtdbm\fR returns a zero status ("true") if the username and password have been successfully added or updated in the DBM File\&. \fBhtdbm\fR returns \fB1\fR if it encounters some problem accessing files, \fB2\fR if there was a syntax problem with the command line, \fB3\fR if the password was entered interactively and the verification entry didn't match, \fB4\fR if its operation was interrupted, \fB5\fR if a value is too long (username, filename, password, or final computed record), \fB6\fR if the username contains illegal characters (see the Restrictions section), and \fB7\fR if the file is not a valid DBM password file\&.
 
.SH "EXAMPLES"
 
.nf

      htdbm /usr/local/etc/apache/\&.htdbm-users jsmith
    
.fi
 
.PP
Adds or modifies the password for user \fBjsmith\fR\&. The user is prompted for the password\&. If executed on a Windows system, the password will be encrypted using the modified Apache MD5 algorithm; otherwise, the system's \fBcrypt()\fR routine will be used\&. If the file does not exist, \fBhtdbm\fR will do nothing except return an error\&.
 
.nf

      htdbm -c /home/doe/public_html/\&.htdbm jane
    
.fi
 
.PP
Creates a new file and stores a record in it for user \fBjane\fR\&. The user is prompted for the password\&. If the file exists and cannot be read, or cannot be written, it is not altered and \fBhtdbm\fR will display a message and return an error status\&.
 
.nf

      htdbm -mb /usr/web/\&.htdbm-all jones Pwd4Steve
    
.fi
 
.PP
Encrypts the password from the command line (\fBPwd4Steve\fR) using the MD5 algorithm, and stores it in the specified file\&.
 
.SH "SECURITY CONSIDERATIONS"
 
.PP
Web password files such as those managed by \fBhtdbm\fR should \fInot\fR be within the Web server's URI space -- that is, they should not be fetchable with a browser\&.
 
.PP
The use of the \fB-b\fR option is discouraged, since when it is used the unencrypted password appears on the command line\&.
 
.PP
When using the \fBcrypt()\fR algorithm, note that only the first 8 characters of the password are used to form the password\&. If the supplied password is longer, the extra characters will be silently discarded\&.
 
.PP
The SHA encryption format does not use salting: for a given password, there is only one encrypted representation\&. The \fBcrypt()\fR and MD5 formats permute the representation by prepending a random salt string, to make dictionary attacks against the passwords more difficult\&.
 
.PP
The SHA and \fBcrypt()\fR formats are insecure by today's standards\&.
 
.SH "RESTRICTIONS"
 
.PP
On the Windows platform, passwords encrypted with \fBhtdbm\fR are limited to no more than \fB255\fR characters in length\&. Longer passwords will be truncated to 255 characters\&.
 
.PP
The MD5 algorithm used by \fBhtdbm\fR is specific to the Apache software; passwords encrypted using it will not be usable with other Web servers\&.
 
.PP
Usernames are limited to \fB255\fR bytes and may not include the character \fB:\fR\&.

.SH "BUGS"
 
.PP
One should be aware that there are a number of different DBM file formats in existence, and with all likelihood, libraries for more than one format may exist on your system\&. The three primary examples are SDBM, NDBM, the GNU project's GDBM, and Berkeley DB 2\&. Unfortunately, all these libraries use different file formats, and you must make sure that the file format used by \fIfilename\fR is the same format that \fBdbmmanage\fR expects to see\&. \fBdbmmanage\fR currently has no way of determining what type of DBM file it is looking at\&. If used against the wrong format, will simply return nothing, or may create a different DBM file with a different name, or at worst, it may corrupt the DBM file if you were attempting to write to it\&.
 
.PP
\fBdbmmanage\fR has a list of DBM format preferences, defined by the \fB@AnyDBM::ISA\fR array near the beginning of the program\&. Since we prefer the Berkeley DB 2 file format, the order in which \fBdbmmanage\fR will look for system libraries is Berkeley DB 2, then NDBM, then GDBM and then SDBM\&. The first library found will be the library \fBdbmmanage\fR will attempt to use for all DBM file transactions\&. This ordering is slightly different than the standard \fB@AnyDBM::ISA\fR ordering in Perl, as well as the ordering used by the simple \fBdbmopen()\fR call in Perl, so if you use any other utilities to manage your DBM files, they must also follow this preference ordering\&. Similar care must be taken if using programs in other languages, like C, to access these files\&.
 
.PP
One can usually use the \fBfile\fR program supplied with most Unix systems to see what format a DBM file is in\&.

.SH "SUMMARY"
 
.PP
\fBapxs\fR is a tool for building and installing extension modules for the Apache HyperText Transfer Protocol (HTTP) server\&. This is achieved by building a dynamic shared object (DSO) from one or more source or object \fIfiles\fR which then can be loaded into the Apache server under runtime via the LoadModule directive from mod_so\&.
 
.PP
So to use this extension mechanism your platform has to support the DSO feature and your Apache httpd binary has to be built with the mod_so module\&. The \fBapxs\fR tool automatically complains if this is not the case\&. You can check this yourself by manually running the command
 
.nf

      $ httpd -l
    
.fi
 
.PP
The module mod_so should be part of the displayed list\&. If these requirements are fulfilled you can easily extend your Apache server's functionality by installing your own modules with the DSO mechanism by the help of this \fBapxs\fR tool:
 
.nf

      $ apxs -i -a -c mod_foo\&.c
      gcc -fpic -DSHARED_MODULE -I/path/to/apache/include -c mod_foo\&.c
      ld -Bshareable -o mod_foo\&.so mod_foo\&.o
      cp mod_foo\&.so /path/to/apache/modules/mod_foo\&.so
      chmod 755 /path/to/apache/modules/mod_foo\&.so
      [activating module `foo' in /path/to/apache/etc/httpd\&.conf]
      $ apachectl restart
      /path/to/apache/sbin/apachectl restart: httpd not running, trying to start
      [Tue Mar 31 11:27:55 1998] [debug] mod_so\&.c(303): loaded module foo_module
      /path/to/apache/sbin/apachectl restart: httpd started
      $ _
    
.fi
 
.PP
The arguments \fIfiles\fR can be any C source file (\&.c), a object file (\&.o) or even a library archive (\&.a)\&. The \fBapxs\fR tool automatically recognizes these extensions and automatically used the C source files for compilation while just using the object and archive files for the linking phase\&. But when using such pre-compiled objects make sure they are compiled for position independent code (PIC) to be able to use them for a dynamically loaded shared object\&. For instance with GCC you always just have to use \fB-fpic\fR\&. For other C compilers consult its manual page or at watch for the flags \fBapxs\fR uses to compile the object files\&.
 
.PP
For more details about DSO support in Apache read the documentation of mod_so or perhaps even read the \fBsrc/modules/standard/mod_so\&.c\fR source file\&.
 

.SH "OPTIONS"
 
.SS "Common Options"
 
 
.TP
\fB-n \fImodname\fR\fR
This explicitly sets the module name for the \fB-i\fR (install) and \fB-g\fR (template generation) option\&. Use this to explicitly specify the module name\&. For option \fB-g\fR this is required, for option \fB-i\fR the \fBapxs\fR tool tries to determine the name from the source or (as a fallback) at least by guessing it from the filename\&.  
  
.SS "Query Options"
 
 
.TP
\fB-q\fR
Performs a query for variables and environment settings used to build \fBhttpd\fR\&. When invoked without \fIquery\fR parameters, it prints all known variables and their values\&. The optional \fB-v\fR parameter formats the list output\&. .PP Use this to manually determine settings used to build the \fBhttpd\fR that will load your module\&. For instance use INC=-I`apxs -q INCLUDEDIR` .PP inside your own Makefiles if you need manual access to Apache's C header files\&.  
  
.SS "Configuration Options"
 
 
.TP
\fB-S \fIname\fR=\fIvalue\fR\fR
This option changes the apxs settings described above\&.  
  
.SS "Template Generation Options"
 
 
.TP
\fB-g\fR
This generates a subdirectory \fIname\fR (see option \fB-n\fR) and there two files: A sample module source file named \fBmod_\fIname\fR\&.c\fR which can be used as a template for creating your own modules or as a quick start for playing with the apxs mechanism\&. And a corresponding \fBMakefile\fR for even easier build and installing of this module\&.  
  
.SS "DSO Compilation Options"
 
 
.TP
\fB-c\fR
This indicates the compilation operation\&. It first compiles the C source files (\&.c) of \fIfiles\fR into corresponding object files (\&.o) and then builds a dynamically shared object in \fIdsofile\fR by linking these object files plus the remaining object files (\&.o and \&.a) of \fIfiles\fR\&. If no \fB-o\fR option is specified the output file is guessed from the first filename in \fIfiles\fR and thus usually defaults to \fBmod_\fIname\fR\&.so\fR\&.  
.TP
\fB-o \fIdsofile\fR\fR
Explicitly specifies the filename of the created dynamically shared object\&. If not specified and the name cannot be guessed from the \fIfiles\fR list, the fallback name \fBmod_unknown\&.so\fR is used\&.  
.TP
\fB-D \fIname\fR=\fIvalue\fR\fR
This option is directly passed through to the compilation command(s)\&. Use this to add your own defines to the build process\&.  
.TP
\fB-I \fIincdir\fR\fR
This option is directly passed through to the compilation command(s)\&. Use this to add your own include directories to search to the build process\&.  
.TP
\fB-L \fIlibdir\fR\fR
This option is directly passed through to the linker command\&. Use this to add your own library directories to search to the build process\&.  
.TP
\fB-l \fIlibname\fR\fR
This option is directly passed through to the linker command\&. Use this to add your own libraries to search to the build process\&.  
.TP
\fB-Wc,\fIcompiler-flags\fR\fR
This option passes \fIcompiler-flags\fR as additional flags to the \fBlibtool --mode=compile\fR command\&. Use this to add local compiler-specific options\&.  
.TP
\fB-Wl,\fIlinker-flags\fR\fR
This option passes \fIlinker-flags\fR as additional flags to the \fBlibtool --mode=link\fR command\&. Use this to add local linker-specific options\&.  
.TP
\fB-p\fR
This option causes apxs to link against the apr/apr-util libraries\&. This is useful when compiling helper programs that use the apr/apr-util libraries\&.  
  
.SS "DSO Installation and Configuration Options"
  
 
.TP
\fB-i\fR
This indicates the installation operation and installs one or more dynamically shared objects into the server's \fImodules\fR directory\&.  
.TP
\fB-a\fR
This activates the module by automatically adding a corresponding LoadModule line to Apache's \fBhttpd\&.conf\fR configuration file, or by enabling it if it already exists\&.  
.TP
\fB-A\fR
Same as option \fB-a\fR but the created LoadModule directive is prefixed with a hash sign (\fB#\fR), \fIi\&.e\&.\fR, the module is just prepared for later activation but initially disabled\&.  
.TP
\fB-e\fR
This indicates the editing operation, which can be used with the \fB-a\fR and \fB-A\fR options similarly to the \fB-i\fR operation to edit Apache's \fBhttpd\&.conf\fR configuration file without attempting to install the module\&.  
  
.SH "EXAMPLES"
 
.PP
Assume you have an Apache module named \fBmod_foo\&.c\fR available which should extend Apache's server functionality\&. To accomplish this you first have to compile the C source into a shared object suitable for loading into the Apache server under runtime via the following command:
 
.nf

      $ apxs -c mod_foo\&.c
      /path/to/libtool --mode=compile gcc \&.\&.\&. -c mod_foo\&.c
      /path/to/libtool --mode=link gcc \&.\&.\&. -o mod_foo\&.la mod_foo\&.slo
      $ _
    
.fi
 
.PP
Then you have to update the Apache configuration by making sure a LoadModule directive is present to load this shared object\&. To simplify this step \fBapxs\fR provides an automatic way to install the shared object in its "modules" directory and updating the \fBhttpd\&.conf\fR file accordingly\&. This can be achieved by running:
 
.nf

      $ apxs -i -a mod_foo\&.la
      /path/to/instdso\&.sh mod_foo\&.la /path/to/apache/modules
      /path/to/libtool --mode=install cp mod_foo\&.la /path/to/apache/modules
      \&.\&.\&.
      chmod 755 /path/to/apache/modules/mod_foo\&.so
      [activating module `foo' in /path/to/apache/conf/httpd\&.conf]
      $ _
    
.fi
 
.PP
This way a line named
 
.nf

      LoadModule foo_module modules/mod_foo\&.so
    
.fi
 
.PP
is added to the configuration file if still not present\&. If you want to have this disabled per default use the \fB-A\fR option, \fIi\&.e\&.\fR
 
.nf

      $ apxs -i -A mod_foo\&.c
    
.fi
 
.PP
For a quick test of the apxs mechanism you can create a sample Apache module template plus a corresponding Makefile via:
 
.nf

      $ apxs -g -n foo
      Creating [DIR]  foo
      Creating [FILE] foo/Makefile
      Creating [FILE] foo/modules\&.mk
      Creating [FILE] foo/mod_foo\&.c
      Creating [FILE] foo/\&.deps
      $ _
    
.fi
 
.PP
Then you can immediately compile this sample module into a shared object and load it into the Apache server:
 
.nf

      $ cd foo
      $ make all reload
      apxs -c mod_foo\&.c
      /path/to/libtool --mode=compile gcc \&.\&.\&. -c mod_foo\&.c
      /path/to/libtool --mode=link gcc \&.\&.\&. -o mod_foo\&.la mod_foo\&.slo
      apxs -i -a -n "foo" mod_foo\&.la
      /path/to/instdso\&.sh mod_foo\&.la /path/to/apache/modules
      /path/to/libtool --mode=install cp mod_foo\&.la /path/to/apache/modules
      \&.\&.\&.
      chmod 755 /path/to/apache/modules/mod_foo\&.so
      [activating module `foo' in /path/to/apache/conf/httpd\&.conf]
      apachectl restart
      /path/to/apache/sbin/apachectl restart: httpd not running, trying to start

Maximum number of seconds to wait before the socket times out\&. Default is 30 seconds\&. Available in 2\&.4\&.4 and later\&.  
.TP
\fB-S\fR
Do not display the median and standard deviation values, nor display the warning/error messages when the average and median are more than one or two times the standard deviation apart\&. And default to the min/avg/max values\&. (legacy support)\&.  
.TP
\fB-t \fItimelimit\fR\fR
Maximum number of seconds to spend for benchmarking\&. This implies a \fB-n 50000\fR internally\&. Use this to benchmark the server within a fixed total amount of time\&. Per default there is no timelimit\&.

.PP
The following list describes the values returned by \fBab\fR:
 
 
.TP
Server Software
The value, if any, returned in the \fIserver\fR HTTP header of the first successful response\&. This includes all characters in the header from beginning to the point a character with decimal value of 32 (most notably: a space or CR/LF) is detected\&.  
.TP
Server Hostname
The DNS or IP address given on the command line  
.TP
Server Port
The port to which ab is connecting\&. If no port is given on the command line, this will default to 80 for http and 443 for https\&.  
.TP
SSL/TLS Protocol
The protocol parameters negotiated between the client and server\&. This will only be printed if SSL is used\&.  
.TP
Document Path
The request URI parsed from the command line string\&.  
.TP
Document Length
This is the size in bytes of the first successfully returned document\&. If the document length changes during testing, the response is considered an error\&.

.TP
Time taken for tests
This is the time taken from the moment the first socket connection is created to the moment the last response is received  
.TP
Complete requests
The number of successful responses received  
.TP
Failed requests
The number of requests that were considered a failure\&. If the number is greater than zero, another line will be printed showing the number of requests that failed due to connecting, reading, incorrect content length, or exceptions\&.  
.TP
Write errors
The number of errors that failed during write (broken pipe)\&.  
.TP
Non-2xx responses

.SH "BUGS"
 
.PP
There are various statically declared buffers of fixed length\&. Combined with the lazy parsing of the command line arguments, the response headers from the server and other external inputs, this might bite you\&.
 
.PP
It does not implement HTTP/1\&.x fully; only accepts some 'expected' forms of responses\&. The rather heavy use of \fBstrstr(3)\fR shows up top in profile, which might indicate a performance problem; \fIi\&.e\&.\fR, you would measure the \fBab\fR performance rather than the server's\&.

.SH "SUMMARY"
 
.PP
\fBlogresolve\fR is a post-processing program to resolve IP-addresses in Apache's access logfiles\&. To minimize impact on your nameserver, logresolve has its very own internal hash-table cache\&. This means that each IP number will only be looked up the first time it is found in the log file\&.
 
.PP
Takes an Apache log file on standard input\&. The IP addresses must be the first thing on each line and must be separated from the remainder of the line by a space\&.
 

.SH "OPTIONS"
 
 
.TP
\fB-s \fIfilename\fR\fR

.TP
\fB-c\fR
This causes \fBlogresolve\fR to apply some DNS checks: after finding the hostname from the IP address, it looks up the IP addresses for the hostname and checks that one of these matches the original address\&.

.TH "APACHECTL" 8 "2018-07-06" "Apache HTTP Server" "apachectl"

.SH NAME
apachectl \- Apache HTTP Server Control Interface

.SH "SYNOPSIS"
 
.PP
When acting in pass-through mode, \fBapachectl\fR can take all the arguments available for the httpd binary\&.
 
.PP
\fB\fBapachectl\fR [ \fIhttpd-argument\fR ]\fR
 
.PP
When acting in SysV init mode, \fBapachectl\fR takes simple, one-word commands, defined below\&.
 
.PP
\fB\fBapachectl\fR \fIcommand\fR\fR
 

.SH "SUMMARY"
 
.PP
\fBapachectl\fR is a front end to the Apache HyperText Transfer Protocol (HTTP) server\&. It is designed to help the administrator control the functioning of the Apache httpd daemon\&.
 
.PP
The \fBapachectl\fR script can operate in two modes\&. First, it can act as a simple front-end to the httpd command that simply sets any necessary environment variables and then invokes httpd, passing through any command line arguments\&. Second, \fBapachectl\fR can act as a SysV init script, taking simple one-word arguments like \fBstart\fR, \fBrestart\fR, and \fBstop\fR, and translating them into appropriate signals to httpd\&.
 
.PP
If your Apache installation uses non-standard paths, you will need to edit the \fBapachectl\fR script to set the appropriate paths to the httpd binary\&. You can also specify any necessary httpd command line arguments\&. See the comments in the script for details\&.
 
.PP
The \fBapachectl\fR script returns a 0 exit value on success, and >0 if an error occurs\&. For more details, view the comments in the script\&.
 

.SH "OPTIONS"
 
.PP
Only the SysV init-style options are defined here\&. Other arguments are defined on the httpd manual page\&.
 
 
.TP
\fBstart\fR
Start the Apache httpd daemon\&. Gives an error if it is already running\&. This is equivalent to \fBapachectl -k start\fR\&.  
.TP
\fBstop\fR
Stops the Apache httpd daemon\&. This is equivalent to \fBapachectl -k stop\fR\&.  
.TP
\fBrestart\fR
Restarts the Apache httpd daemon\&. If the daemon is not running, it is started\&. This command automatically checks the configuration files as in \fBconfigtest\fR before initiating the restart to make sure the daemon doesn't die\&. This is equivalent to \fBapachectl -k restart\fR\&.  
.TP
\fBfullstatus\fR
Displays a full status report from mod_status\&. For this to work, you need to have mod_status enabled on your server and a text-based browser such as \fBlynx\fR available on your system\&. The URL used to access the status report can be set by editing the \fBSTATUSURL\fR variable in the script\&.  
.TP
\fBstatus\fR
Displays a brief status report\&. Similar to the \fBfullstatus\fR option, except that the list of requests currently being served is omitted\&.  
.TP
\fBgraceful\fR
Gracefully restarts the Apache httpd daemon\&. If the daemon is not running, it is started\&. This differs from a normal restart in that currently open connections are not aborted\&. A side effect is that old log files will not be closed immediately\&. This means that if used in a log rotation script, a substantial delay may be necessary to ensure that the old log files are closed before processing them\&. This command automatically checks the configuration files as in \fBconfigtest\fR before initiating the restart to make sure Apache doesn't die\&. This is equivalent to \fBapachectl -k graceful\fR\&.  
.TP
\fBgraceful-stop\fR
Gracefully stops the Apache httpd daemon\&. This differs from a normal stop in that currently open connections are not aborted\&. A side effect is that old log files will not be closed immediately\&. This is equivalent to \fBapachectl -k graceful-stop\fR\&.  
.TP
\fBconfigtest\fR
Run a configuration file syntax test\&. It parses the configuration files and either reports \fBSyntax Ok\fR or detailed information about the particular syntax error\&. This is equivalent to \fBapachectl -t\fR\&.  
 
.PP
The following option was available in earlier versions but has been removed\&.
 
 
.TP
\fBstartssl\fR
To start httpd with SSL support, you should edit your configuration file to include the relevant directives and then use the normal \fBapachectl start\fR\&.

.TH "ROTATELOGS" 8 "2020-06-10" "Apache HTTP Server" "rotatelogs"

.SH NAME
rotatelogs \- Piped logging program to rotate Apache logs

.SH "SYNOPSIS"
 
.PP
\fB\fBrotatelogs\fR [ -\fBl\fR ] [ -\fBL\fR \fIlinkname\fR ] [ -\fBp\fR \fIprogram\fR ] [ -\fBf\fR ] [ -\fBD\fR ] [ -\fBt\fR ] [ -\fBv\fR ] [ -\fBe\fR ] [ -\fBc\fR ] [ -\fBn\fR \fInumber-of-files\fR ] \fIlogfile\fR \fIrotationtime\fR|\fIfilesize\fR(B|K|M|G) [ \fIoffset\fR ]\fR
 

.SH "SUMMARY"
 
.PP
\fBrotatelogs\fR is a simple program for use in conjunction with Apache's piped logfile feature\&. It supports rotation based on a time interval or maximum size of the log\&.
 

.SH "OPTIONS"
 
 
.TP
\fB-l\fR
Causes the use of local time rather than GMT as the base for the interval or for \fBstrftime(3)\fR formatting with size-based rotation\&.  
.TP
\fB-L\fR \fIlinkname\fR
.PP Causes a hard link to be made from the current logfile to the specified link name\&. This can be used to watch the log continuously across rotations using a command like \fBtail -F linkname\fR\&. .PP If the linkname is not an absolute path, it is relative to \fBrotatelogs\fR' working directory, which is the ServerRoot when \fBrotatelogs\fR is run by the server\&.  
.TP
\fB-p\fR \fIprogram\fR
If given, \fBrotatelogs\fR will execute the specified program every time a new log file is opened\&. The filename of the newly opened file is passed as the first argument to the program\&. If executing after a rotation, the old log file is passed as the second argument\&. \fBrotatelogs\fR does not wait for the specified program to terminate before continuing to operate, and will not log any error code returned on termination\&. The spawned program uses the same stdin, stdout, and stderr as rotatelogs itself, and also inherits the environment\&.  
.TP
\fB-f\fR
Causes the logfile to be opened immediately, as soon as \fBrotatelogs\fR starts, instead of waiting for the first logfile entry to be read (for non-busy sites, there may be a substantial delay between when the server is started and when the first request is handled, meaning that the associated logfile does not "exist" until then, which causes problems from some automated logging tools)  
.TP
\fB-D\fR
Creates the parent directories of the path that the log file will be placed in if they do not already exist\&. This allows \fBstrftime(3)\fR formatting to be used in the path and not just the filename\&.  
.TP
\fB-t\fR
Causes the logfile to be truncated instead of rotated\&. This is useful when a log is processed in real time by a command like tail, and there is no need for archived data\&. No suffix will be added to the filename, however format strings containing '%' characters will be respected\&.  
.TP
\fB-v\fR
Produce verbose output on STDERR\&. The output contains the result of the configuration parsing, and all file open and close actions\&.  
.TP
\fB-e\fR
Echo logs through to stdout\&. Useful when logs need to be further processed in real time by a further tool in the chain\&.  
.TP
\fB-c\fR
Create log file for each interval, even if empty\&.  
.TP
\fB-n \fInumber-of-files\fR\fR
Use a circular list of filenames without timestamps\&. With -n 3, the series of log files opened would be "logfile", "logfile\&.1", "logfile\&.2", then overwriting "logfile"\&. Available in 2\&.4\&.5 and later\&.  
.TP
\fB\fIlogfile\fR\fR
.PP The path plus basename of the logfile\&. If \fIlogfile\fR includes any '%' characters, it is treated as a format string for \fBstrftime(3)\fR\&. Otherwise, the suffix \fI\&.nnnnnnnnnn\fR is automatically added and is the time in seconds (unless the -t option is used)\&. Both formats compute the start time from the beginning of the current period\&. For example, if a rotation time of 86400 is specified, the hour, minute, and second fields created from the \fBstrftime(3)\fR format will all be zero, referring to the beginning of the current 24-hour period (midnight)\&. .PP When using \fBstrftime(3)\fR filename formatting, be sure the log file format has enough granularity to produce a different file name each time the logs are rotated\&. Otherwise rotation will overwrite the same file instead of starting a new one\&. For example, if \fIlogfile\fR was \fB/var/log/errorlog\&.%Y-%m-%d\fR with log rotation at 5 megabytes, but 5 megabytes was reached twice in the same day, the same log file name would be produced and log rotation would keep writing to the same file\&. .PP If the logfile is not an absolute path, it is relative to \fBrotatelogs\fR' working directory, which is the ServerRoot when \fBrotatelogs\fR is run by the server\&.  
.TP
\fB\fIrotationtime\fR\fR
The time between log file rotations in seconds\&. The rotation occurs at the beginning of this interval\&. For example, if the rotation time is 3600, the log file will be rotated at the beginning of every hour; if the rotation time is 86400, the log file will be rotated every night at midnight\&. (If no data is logged during an interval, no file will be created\&.)  
.TP
\fB\fIfilesize\fR(B|K|M|G)\fR
The maximum file size in followed by exactly one of the letters \fBB\fR (Bytes), \fBK\fR (KBytes), \fBM\fR (MBytes) or \fBG\fR (GBytes)\&. .PP When time and size are specified, the size must be given after the time\&. Rotation will occur whenever either time or size limits are reached\&.  
.TP
\fB\fIoffset\fR\fR
The number of minutes offset from UTC\&. If omitted, zero is assumed and UTC is used\&. For example, to use local time in the zone UTC -5 hours, specify a value of \fB-300\fR for this argument\&. In most cases, \fB-l\fR should be used instead of specifying an offset\&.  
 
.SH "EXAMPLES"
 
.nf

     CustomLog "|bin/rotatelogs /var/log/logfile 86400" common

.fi
 
.PP
This creates the files /var/log/logfile\&.nnnn where nnnn is the system time at which the log nominally starts (this time will always be a multiple of the rotation time, so you can synchronize cron scripts with it)\&. At the end of each rotation time (here after 24 hours) a new log is started\&.
 
.nf

     CustomLog "|bin/rotatelogs -l /var/log/logfile\&.%Y\&.%m\&.%d 86400" common

.fi
 
.PP
This creates the files /var/log/logfile\&.yyyy\&.mm\&.dd where yyyy is the year, mm is the month, and dd is the day of the month\&. Logging will switch to a new file every day at midnight, local time\&.
 
.nf

     CustomLog "|bin/rotatelogs /var/log/logfile 5M" common

.fi
 
.PP
This configuration will rotate the logfile whenever it reaches a size of 5 megabytes\&.
 
.nf

     ErrorLog "|bin/rotatelogs /var/log/errorlog\&.%Y-%m-%d-%H_%M_%S 5M"

.fi
 
.PP
This configuration will rotate the error logfile whenever it reaches a size of 5 megabytes, and the suffix to the logfile name will be created of the form \fBerrorlog\&.YYYY-mm-dd-HH_MM_SS\fR\&.
 
.nf

     CustomLog "|bin/rotatelogs -t /var/log/logfile 86400" common

.fi
 
.PP
This creates the file /var/log/logfile, truncating the file at startup and then truncating the file once per day\&. It is expected in this scenario that a separate process (such as tail) would process the file in real time\&.
 
.SH "PORTABILITY"
 
.PP
The following logfile format string substitutions should be supported by all \fBstrftime(3)\fR implementations, see the \fBstrftime(3)\fR man page for library-specific extensions\&.

.SH "SUMMARY"
 
.PP
\fBhtpasswd\fR is used to create and update the flat-files used to store usernames and password for basic authentication of HTTP users\&. If \fBhtpasswd\fR cannot access a file, such as not being able to write to the output file or not being able to read the file in order to update it, it returns an error status and makes no changes\&.
 
.PP
Resources available from the Apache HTTP server can be restricted to just the users listed in the files created by \fBhtpasswd\fR\&. This program can only manage usernames and passwords stored in a flat-file\&. It can encrypt and display password information for use in other types of data stores, though\&. To use a DBM database see dbmmanage or htdbm\&.
 
.PP
\fBhtpasswd\fR encrypts passwords using either bcrypt, a version of MD5 modified for Apache, SHA1, or the system's \fBcrypt()\fR routine\&. Files managed by \fBhtpasswd\fR may contain a mixture of different encoding types of passwords; some user records may have bcrypt or MD5-encrypted passwords while others in the same file may have passwords encrypted with \fBcrypt()\fR\&.
 
.PP
This manual page only lists the command line arguments\&. For details of the directives necessary to configure user authentication in httpd see the Apache manual, which is part of the Apache distribution or can be found at http://httpd\&.apache\&.org/\&.
 

.SH "OPTIONS"
 
 
.TP
\fB-b\fR
Use batch mode; \fIi\&.e\&.\fR, get the password from the command line rather than prompting for it\&. This option should be used with extreme care, since \fBthe password is clearly visible\fR on the command line\&. For script use see the \fB-i\fR option\&. Available in 2\&.4\&.4 and later\&.  
.TP
\fB-i\fR
Read the password from stdin without verification (for script usage)\&.  
.TP
\fB-c\fR
Create the \fIpasswdfile\fR\&. If \fIpasswdfile\fR already exists, it is rewritten and truncated\&. This option cannot be combined with the \fB-n\fR option\&.  
.TP
\fB-n\fR
Display the results on standard output rather than updating a file\&. This is useful for generating password records acceptable to Apache for inclusion in non-text data stores\&. This option changes the syntax of the command line, since the \fIpasswdfile\fR argument (usually the first one) is omitted\&. It cannot be combined with the \fB-c\fR option\&.  
.TP
\fB-m\fR
Use MD5 encryption for passwords\&. This is the default (since version 2\&.2\&.18)\&.  
.TP
\fB-B\fR
Use bcrypt encryption for passwords\&. This is currently considered to be very secure\&.  
.TP
\fB-C\fR
This flag is only allowed in combination with \fB-B\fR (bcrypt encryption)\&. It sets the computing time used for the bcrypt algorithm (higher is more secure but slower, default: 5, valid: 4 to 17)\&.  
.TP
\fB-d\fR
Use \fBcrypt()\fR encryption for passwords\&. This is not supported by the httpd server on Windows and Netware\&. This algorithm limits the password length to 8 characters\&. This algorithm is \fBinsecure\fR by today's standards\&. It used to be the default algorithm until version 2\&.2\&.17\&.  
.TP
\fB-s\fR
Use SHA encryption for passwords\&. Facilitates migration from/to Netscape servers using the LDAP Directory Interchange Format (ldif)\&. This algorithm is \fBinsecure\fR by today's standards\&.  
.TP
\fB-p\fR
Use plaintext passwords\&. Though \fBhtpasswd\fR will support creation on all platforms, the httpd daemon will only accept plain text passwords on Windows and Netware\&.  
.TP
\fB-D\fR
Delete user\&. If the username exists in the specified htpasswd file, it will be deleted\&.  
.TP
\fB-v\fR
Verify password\&. Verify that the given password matches the password of the user stored in the specified htpasswd file\&. Available in 2\&.4\&.5 and later\&.  
.TP
\fB\fIpasswdfile\fR\fR
Name of the file to contain the user name and password\&. If \fB-c\fR is given, this file is created if it does not already exist, or rewritten and truncated if it does exist\&.  
.TP
\fB\fIusername\fR\fR
The username to create or update in \fIpasswdfile\fR\&. If \fIusername\fR does not exist in this file, an entry is added\&. If it does exist, the password is changed\&.  
.TP
\fB\fIpassword\fR\fR
The plaintext password to be encrypted and stored in the file\&. Only used with the \fB-b\fR flag\&.  
 
.SH "EXIT STATUS"
 
.PP
\fBhtpasswd\fR returns a zero status ("true") if the username and password have been successfully added or updated in the \fIpasswdfile\fR\&. \fBhtpasswd\fR returns \fB1\fR if it encounters some problem accessing files, \fB2\fR if there was a syntax problem with the command line, \fB3\fR if the password was entered interactively and the verification entry didn't match, \fB4\fR if its operation was interrupted, \fB5\fR if a value is too long (username, filename, password, or final computed record), \fB6\fR if the username contains illegal characters (see the Restrictions section), and \fB7\fR if the file is not a valid password file\&.
 
.SH "EXAMPLES"
 
.nf

      htpasswd /usr/local/etc/apache/\&.htpasswd-users jsmith
    
.fi
 
.PP
Adds or modifies the password for user \fBjsmith\fR\&. The user is prompted for the password\&. The password will be encrypted using the modified Apache MD5 algorithm\&. If the file does not exist, \fBhtpasswd\fR will do nothing except return an error\&.
 
.nf

      htpasswd -c /home/doe/public_html/\&.htpasswd jane
    
.fi
 
.PP
Creates a new file and stores a record in it for user \fBjane\fR\&. The user is prompted for the password\&. If the file exists and cannot be read, or cannot be written, it is not altered and \fBhtpasswd\fR will display a message and return an error status\&.
 
.nf

      htpasswd -db /usr/web/\&.htpasswd-all jones Pwd4Steve
    
.fi
 
.PP
Encrypts the password from the command line (\fBPwd4Steve\fR) using the \fBcrypt()\fR algorithm, and stores it in the specified file\&.
 
.SH "SECURITY CONSIDERATIONS"
 
.PP
Web password files such as those managed by \fBhtpasswd\fR should \fInot\fR be within the Web server's URI space -- that is, they should not be fetchable with a browser\&.
 
.PP
This program is not safe as a setuid executable\&. Do \fInot\fR make it setuid\&.
 
.PP
The use of the \fB-b\fR option is discouraged, since when it is used the unencrypted password appears on the command line\&.
 
.PP
When using the \fBcrypt()\fR algorithm, note that only the first 8 characters of the password are used to form the password\&. If the supplied password is longer, the extra characters will be silently discarded\&.
 
.PP
The SHA encryption format does not use salting: for a given password, there is only one encrypted representation\&. The \fBcrypt()\fR and MD5 formats permute the representation by prepending a random salt string, to make dictionary attacks against the passwords more difficult\&.
 
.PP
The SHA and \fBcrypt()\fR formats are insecure by today's standards\&.
 
.SH "RESTRICTIONS"
 
.PP
On the Windows platform, passwords encrypted with \fBhtpasswd\fR are limited to no more than \fB255\fR characters in length\&. Longer passwords will be truncated to 255 characters\&.
 
.PP
The MD5 algorithm used by \fBhtpasswd\fR is specific to the Apache software; passwords encrypted using it will not be usable with other Web servers\&.
 
.PP
Usernames are limited to \fB255\fR bytes and may not include the character \fB:\fR\&.
 
.PP
The cost of computing a bcrypt password hash value increases with the number of rounds specified by the \fB-C\fR option\&. The \fBapr-util\fR library enforces a maximum number of rounds of 17 in version \fB1\&.6\&.0\fR and later\&.

.SH "SUMMARY"
 
.PP
\fBhtcacheclean\fR is used to keep the size of mod_cache_disk's storage within a given size limit, or limit on inodes in use\&. This tool can run either manually or in daemon mode\&. When running in daemon mode, it sleeps in the background and checks the cache directory at regular intervals for cached content to be removed\&. You can stop the daemon cleanly by sending it a TERM or INT signal\&. When run manually, a once off check of the cache directory is made for cached content to be removed\&. If one or more URLs are specified, each URL will be deleted from the cache, if present\&.
 

.SH "OPTIONS"
 
 
.TP
\fB-d\fIinterval\fR\fR
Daemonize and repeat cache cleaning every \fIinterval\fR minutes\&. This option is mutually exclusive with the \fB-D\fR, \fB-v\fR and \fB-r\fR options\&. To shutdown the daemon cleanly, just send it a \fBSIGTERM\fR or \fBSIGINT\fR\&.  
.TP
\fB-D\fR
Do a dry run and don't delete anything\&. This option is mutually exclusive with the \fB-d\fR option\&. When doing a dry run and deleting directories with \fB-t\fR, the inodes reported deleted in the stats cannot take into account the directories deleted, and will be marked as an estimate\&.  
.TP
\fB-v\fR
Be verbose and print statistics\&. This option is mutually exclusive with the \fB-d\fR option\&.  
.TP
\fB-r\fR
Clean thoroughly\&. This assumes that the Apache web server is not running (otherwise you may get garbage in the cache)\&. This option is mutually exclusive with the \fB-d\fR option and implies the \fB-t\fR option\&.  
.TP
\fB-n\fR
Be nice\&. This causes slower processing in favour of other processes\&. \fBhtcacheclean\fR will sleep from time to time so that (a) the disk IO will be delayed and (b) the kernel can schedule other processes in the meantime\&.  
.TP
\fB-t\fR
Delete all empty directories\&. By default only cache files are removed, however with some configurations the large number of directories created may require attention\&. If your configuration requires a very large number of directories, to the point that inode or file allocation table exhaustion may become an issue, use of this option is advised\&.  
.TP
\fB-p\fIpath\fR\fR
Specify \fIpath\fR as the root directory of the disk cache\&. This should be the same value as specified with the CacheRoot directive\&.  
.TP
\fB-P\fIpidfile\fR\fR
Specify \fIpidfile\fR as the name of the file to write the process ID to when daemonized\&.  
.TP
\fB-R\fIround\fR\fR
Specify \fIround\fR as the amount to round sizes up to, to compensate for disk block sizes\&. Set to the block size of the cache partition\&.  
.TP
\fB-l\fIlimit\fR\fR
Specify \fIlimit\fR as the total disk cache size limit\&. The value is expressed in bytes by default (or attaching \fBB\fR to the number)\&. Attach \fBK\fR for Kbytes, \fBM\fR for MBytes or \fBG\fR for Gbytes\&.  
.TP
\fB-L\fIlimit\fR\fR
Specify \fIlimit\fR as the total disk cache inode limit\&. \fBK\fR, \fBM\fR or \fBG\fR suffix can also be used\&.  
.TP
\fB-i\fR
Be intelligent and run only when there was a modification of the disk cache\&. This option is only possible together with the \fB-d\fR option\&.  
.TP
\fB-a\fR
List the URLs currently stored in the cache\&. Variants of the same URL will be listed once for each variant\&.  
.TP
\fB-A\fR
List the URLs currently stored in the cache, along with their attributes in the following order: url, header size, body size, status, entity version, date, expiry, request time, response time, body present, head request\&.  
 
.SH "DELETING A SPECIFIC URL"
 
.PP
If \fBhtcacheclean\fR is passed one or more URLs, each URL will be deleted from the cache\&. If multiple variants of an URL exists, all variants would be deleted\&.
 
.PP
When a reverse proxied URL is to be deleted, the effective URL is constructed from the \fBHost\fR header, the \fBport\fR, the \fBpath\fR and the \fBquery\fR\&. Note the '?' in the URL must always be specified explicitly, whether a query string is present or not\&. For example, an attempt to delete the path \fB/\fR from the server \fBlocalhost\fR, the URL to delete would be \fBhttp://localhost:80/?\fR\&.
 
.SH "LISTING URLS IN THE CACHE"
 
.PP
By passing the \fB-a\fR or \fB-A\fR options to \fBhtcacheclean\fR, the URLs within the cache will be listed as they are found, one URL per line\&. The \fB-A\fR option dumps the full cache entry after the URL, with fields in the following order:
 
 
.TP
url
The URL of the entry\&. 
.TP
header size
The size of the header in bytes\&. 
.TP
body size
The size of the body in bytes\&. 
.TP
status
Status of the cached response\&. 
.TP
entity version
The number of times this entry has been revalidated without being deleted\&. 
.TP
date
Date of the response\&. 
.TP
expiry
Expiry date of the response\&. 
.TP
request time
Time of the start of the request\&. 
.TP
response time
Time of the end of the request\&. 
.TP
body present
If 0, no body is stored with this request, 1 otherwise\&. 
.TP
head request
If 1, the entry contains a cached HEAD request with no body, 0 otherwise\&. 
 
.SH "EXIT STATUS"
 
.PP
\fBhtcacheclean\fR returns a zero status ("true") if all operations were successful, \fB1\fR otherwise\&. If an URL is specified, and the URL was cached and successfully removed, \fB0\fR is returned, \fB2\fR otherwise\&. If an error occurred during URL removal, \fB1\fR is returned\&.

.SH "ÖRNEKLER"
 
.PP
Apache'nin sunucu işlevselliğini genişletmek amacıyla kullanacağınız mod_foo\&.c adında bir Apache modülünüz olduğunu varsayalım\&. Öncelikle, C kaynak dosyasını, Apache sunucusuna çalışma anında yüklenmeye uygun bir paylaşımlı nesne olarak derlemeniz gerekir\&. Bunu sağlamak için şu komutları vermelisiniz:
 
.nf

      $ apxs -c mod_foo\&.c
      /dosya/yolu/libtool --mode=compile gcc \&.\&.\&. -c mod_foo\&.c
      /dosya/yolu/libtool --mode=link gcc \&.\&.\&. -o mod_foo\&.la mod_foo\&.slo
      $ _
    
.fi
 
.PP
Bundan sonra, Apache yapılandırmanızın bu paylaşımlı nesneyi yüklemek için bir \fBLoadModule\fR yönergesi içermesini sağlamalısınız\&. \fBapxs\fR bu adımı basitleştirmek amacıyla, paylaşımlı nesneyi sunucunun \fImodules\fR dizinine özdevinimli olarak kurmak ve httpd\&.conf dosyasını buna uygun olarak güncellemek için bir yol sağlar\&. Bu sonuç şöyle elde edilebilir:
 
.nf

      $ apxs -i -a mod_foo\&.la
      /dosya/yolu/instdso\&.sh mod_foo\&.la /path/to/apache/modules
      /dosya/yolu/libtool --mode=install cp mod_foo\&.la /dosya/yolu/apache/modules
      \&.\&.\&.
      chmod 755 /dosya/yolu/apache/modules/mod_foo\&.so
      [`foo' modülü /dosya/yolu/apache/conf/httpd\&.conf'da etkinleştiriliyor] 
      $ _
    
.fi
 
.PP
Yapılandıma dosyasına (eğer yoksa) şu satır eklenir:
 
.nf

      LoadModule foo_module modules/mod_foo\&.so
    
.fi
 
.PP
Bunu öntanımlı olarak iptal etmek isterseniz \fB-A\fR seçeneğini kullanmanız gerekir:
 
.nf

      $ apxs -i -A mod_foo\&.c
    
.fi
 
.PP
\fBapxs\fR mekanizmalarını hızlıca denemek için örnek bir Apache modül şablonunu ve bir Makefile dosyasını şöyle oluşturabilirsiniz:
 
.nf

      $ apxs -g -n foo
      Creating [DIR]  foo
      Creating [FILE] foo/Makefile
      Creating [FILE] foo/modules\&.mk
      Creating [FILE] foo/mod_foo\&.c
      Creating [FILE] foo/\&.deps
      $ _
    
.fi
 
.PP
Ardından bu örnek modülü bir paylaşımlı nesne olarak derleyip Apache sunucusuna yükleyebilirsiniz:
 
.nf

      $ cd foo
      $ make all reload
      apxs -c mod_foo\&.c
      /dosya/yolu/libtool --mode=compile gcc \&.\&.\&. -c mod_foo\&.c
      /dosya/yolu/libtool --mode=link gcc \&.\&.\&. -o mod_foo\&.la mod_foo\&.slo

\fBapachectl\fR iki kipte işleyebilir\&. İlkinde, \fBhttpd\fR komutu için basit bir önyüz gibi davranarak, gerekli ortam değişkenlerini atar ve belirtilen komut satırı seçenekleriyle \fBhttpd\fR sürecini başlatır\&. İkinci kipte ise, \fBapachectl\fR bir SysV başlatma betiği olarak \fBstart\fR, \fBrestart\fR, \fBstop\fR gibi tek sözcüklük basit argümanlar alır ve bunları uygun sinyallere dönüştürerek \fBhttpd\fR'ye gönderir\&.
 
.PP
Eğer Apache kurulumunuzda standart dışı dosya yolları kullanmışsanız, \fBhttpd\fR programına uygun yolları atamak için \fBapachectl\fR betiğini elden geçirmelisiniz\&. Bu arada gerek gördüğünüz \fBhttpd\fR komut satırı argümanlarını da belirtebilirsiniz\&. Ayrıntılar için betik içindeki açıklamalara bakınız\&.
 
.PP
\fBapachectl\fR betiği başarı durumunda 0 çıkış değeri ile döner\&. Bir hata durumunda ise sıfırdan farklı bir değerle döner\&. Daha fazla bilgi için betik içindeki açıklamalara bakınız\&.

\fB-l\fR
GMT yerine yerel zamanın kullanılmasını sağlar\&.  
.TP
\fB-L\fR \fIbagismi\fR
Belirtilen bağ dosyası ismine geçerli günlük dosyasından kalıcı bir bağ oluşturulur\&. tail -F bagismi gibi bir komut kullanılarak günlüğün sürekli izlenmesi için kullanılabilir\&.  
.TP
\fB-p\fR \fIprogram\fR
Belirtildiği takdirde, \fBrotatelogs\fR yeni bir günlük dosyasının her açılışında belirtilen programı çalıştırır\&. Yeni açılan dosyanın ismi programa ilk argüman olarak aktarılır\&. Bu işlem bir döndürme sonrası yapılırsa eski günlük dosyası ikinci argüman olarak aktarılır\&. \fBrotatelogs\fR işlemini sürdürmek için belirtilen programın sonlanmasını beklemez, dolayısıyla sonlanma soucunda döndürülen hata kodunu günlüğe kaydetmez\&. Çalıştırılan program \fBrotatelogs\fR ile aynı stdin, stdout ve stderr'i kullanır ve ortamı da miras alır\&.  
.TP
\fB-f\fR
İlk günlük giridisinin okunmasını beklemeden \fBrotatelogs\fR başlar başlamaz günlük dosyasının açılmasını sağlar\&. Çok meşgul sitelerde, sunucu başlatılıp ilk istek sunuluncaya kadar geçen zamanda günlük dosyasının yokluğu özdevinimli işlemler yapan bazı günlükleme araçlarında sorunlara yol açabilir\&. Bu seçenek bu gibi durumlarda yararlıdır\&.  
.TP
\fB-t\fR
Günlük dosyasının döndürülmek yerine tepeden kırpılmasına sebep olur\&. Günlüğün \fBtail\fR gibi bir araç tarafından gerçek zamanda işlendiği ve veriyi saklamanın gerekmediği durumda kullanışlıdır\&. Dosya ismine bir sonek eklenmez, ancak biçem dizgesi '%' karakteri içeriyorsa buna uyulur\&.  
.TP
\fB-v\fR
Standart hataya verilen çıktı daha ayrıntılı olur\&. Çıktı, yapılandırma çözümlemesinin sonuçlarını ve tüm dosya açma/kapama işlemlerini içerir\&.  
.TP
\fB-e\fR
Günlüğü standart çıktıya basar\&. Günlüğün zincirdeki ilgili araç tarafından gerçek zamanda işlenmesi gerektiğinde kullanışlıdır\&.  
.TP
\fB-c\fR
Create log file for each interval, even if empty\&.  
.TP
\fB-n\fR \fIdosya_sayısı\fR
Zaman damgalarına bakılmaksızın bir dosya serisi açılır\&. Örneğin -n3 belirtilirse "logfile", "logfile\&.1", "logfile\&.2" serisi açılır ve "logfile" üzerine yazılır\&. 2\&.4\&.5 ve sonraki sürümler içindir\&.  
.TP
\fIdosyaismi\fR
.PP Günlük dosyasının ismi yoluyla birlikte belirtilir\&. \fIdosyaismi\fR '%' karakterleri içeriyorsa bunlar strftime(3) biçem belirteçleri olarak ele alınır\&. Aksi takdirde, özdevinimli olarak \fI\&.nnnnnnnnnn\fR uzantısı üretilir\&. (\fB-t\fR seçeneği kullanılmadıkça) Uzantı saniye cinsindendir ve her iki durumda da bu değer, mevcut döngü diliminin başlangıcına göre hesaplanır\&. Örneğin, döndürmenin 86400 saniyede bir yapılacağı belirtilmişse, strftime(3) biçeminde oluşturulan saat, dakika ve saniye alanları, 24 saatlik sürenin başlangıcını (geceyarısı) göstermek üzere sıfırlarla doldurulur\&. .PP strftime(3) dosyaismi biçemlemesi kullanılırken, günlük dosyası biçeminin günlük dosyası döndürülürken her zaman farklı bir dosya ismi üretecek yeterlilikte parçacıklı yapıya sahip olduğundan emin olmalısınız\&. Aks takdirde döndürme işlemi yeni bir dosya başlatmak yerine hep aynı dosyanın üzerine yazar\&. Örneğin, \fIlogfile\fR için /var/log/errorlog\&.%Y-%m-%d belirtilmişse 5 mega baytta bir yeni bir günlük dosyasına başlanacaktır\&. Fakat 5 megabayta gün içinde iki kez ulaşılırsa aynı günlük dosyası üretilir ve günlük hep aynı dosyanın üzerine yazılır\&.  
.TP
\fIsüre\fR
Günlük dosyasının yenisinin kaç saniyede bir açılacağı belirtilir\&. Örneğin, bu süre 3600 saniye ise günlük dosyası her saat başında yenilenir; 86400 saniye ise her geceyarısı yenilenir\&. (Bu süre zarfında günlüğe kaydedilecek bir olay gerçekleşmemişse dosya oluşturulmaz\&.)  
.TP
\fIboyut\fR(B|K|M|G)
Boyuta göre döndürme için azami dosya boyutu\&. Belirtilenin bir süre değil de bir boyut değeri olarak ele alınması için değerin sonuna şu karakterlerden biri eklenmelidir: B (Bayt), K (kilobayt), M (megabayt), G (gigabayt)\&. .PP Süre ve boyut birlikte belirtilmişse boyut süreden sonra belirtilmelidir\&. Dosya yenilemesi, bunlardan hangisi daha önce aşılırsa o zaman gerçekleşir\&.  
.TP
\fIsaat_farkı\fR
Koordinatlı evrensel zamana göre "dakika" farkı\&. Belirtilmezse, sıfır öntanımlıdır\&. Örneğin, -5 saatlik bir zaman diliminde bulunuyorsanız bu değer -300 olmalıdır\&. Çoğu durumda, bunun yerine \fB-l\fR seçeneğini kullanmak gerekir\&.

.SH "ÖZET"
 
.PP
\fBhtpasswd\fR, HTTP kullanıcılarının temel kimlik doğrulaması için kullanıcı isimlerinin ve parolalarının saklanmasında kullanılacak düz metin dosyalarını oluşturmak ve güncellemek için kullanılır\&. \fBhtpasswd\fR, güncelleme sırasında yazmak veya okumak için bir dosyaya erişemezse beklenen hiçbir işlemi yapmaz ve hata vererek çıkar\&.
 
.PP
Apache HTTP sunucusunun mevcut özkaynaklarının kullanımı sadece \fBhtpasswd\fR tarafından oluşturulan dosyalarda listelenmiş kullanıcılara tahsis edilebilir\&. \fBhtpasswd\fR sadece düz metin dosyalarda saklanmış kullanıcı isimlerini ve parolalarını yönetirse de, diğer veri saklama türleri için parolayı şifreleyip gösterebilir\&. Bir DBM veritabanı kullanmak isterseniz \fBdbmmanage\fR ve \fBhtdbm\fR sayfasına bakınız\&.
 
.PP
\fBhtpasswd\fR, parolaları şifrelemek için bcrypt, Apache'nin kendine özgü MD5 algoritması, SHA1 ya da sistemin crypt() yordamını kullanır\&. Bu bakımdan \fBhtpasswd\fR tarafından yönetilen dosyalar farklı algoritmalarla şifrelenmiş parolalar içerebilir\&.
 
.PP
Bu kılavuz sayfası sadece komut satırı değiştirgelerini listeler\&. Kullanıcı kimlik doğrulamasını \fBhttpd\fR'de yapılandırmak için gerekli yönergelerle ilgili ayrıntılar için Apache dağıtımının bir parçası olan ve http://httpd\&.apache\&.org/ adresinde de bulunan Apache HTTP Sunucusu Belgelerine bakınız\&.
 

.SH "SEÇENEKLER"
 
 
.TP
\fB-b\fR
Betik kipi; parola için istek yapmak yerine parola komut satırından verilir\&. \fBParola komut satırında görünür\fR olacağından çok dikkatli kullanmak gerekir\&. Betik kullanımı için \fB-i\fR seçeneğine bakınız\&. 2\&.4\&.4 ve sonraki sürümler içindir\&.  
.TP
\fB-i\fR
Parolayı doğrulamaksızın standart girdiden okur (betik kullanımı için)\&.  
.TP
\fB-c\fR
\fIparola-dosyası\fR oluşturur\&. Dosya mevcutsa, dosya silinip yeniden yazılır\&. Bu seçenek \fB-n\fR seçeneği ile birlikte kullanılamaz\&.  
.TP
\fB-n\fR
Sonuçları veritabanında güncellemek yerine standart çıktıya gönderir\&. Bu seçenek, Apache'nin metin veriler içermeyen veri depolarına dahil edilebilecek parolaları üretmekte yararlıdır\&. \fIparola-dosyası\fR belirtilmediğinden, bu seçenek komut satırı sözdizimini değiştirir\&. Bu seçenek \fB-c\fR seçeneği ile birlikte kullanılamaz\&.  
.TP
\fB-m\fR
Parolalar için MD5 şifrelemesi kullanılır\&. Bu 2\&.2\&.18 sürümünden beri öntanımlıdır\&.  
.TP
\fB-B\fR
Parolalar için bcrypt şifrelemesi kullanılır\&. Şu an için çok güvenli kabul edilmektedir\&.  
.TP
\fB-C\fR \fIbedel\fR
Bu seçenek sadece \fB-B\fR (bcrypt şifrelemesi) seçeneği ile birlikte kullanılabilir\&. Bcrypt algoritmasına hesaplama süresini belirtir (daha yüksek değerler daha güvenlidir, öntanımlı 5, geçerli değerler: 4 - 31)\&.  
.TP
\fB-d\fR
Parolaları şifrelemek için crypt() kullanılır\&. \fBhtpasswd\fR tarafından tüm platformlarda destekleniyor olsa da Windows, Netware ve TPF üzerinde httpd sunucusu tarafından desteklenmez\&. Bu algoritma günümüz standartlarında \fBgüvenilmez\fR kabul edilmektedir\&. 2\&.2\&.17 sürümüne kadar öntanımlı algoritma olarak kullanılmıştı\&.  
.TP
\fB-s\fR
Parolalar için SHA şifrelemesi kullanılır\&. LDAP Dizin değişim biçemini (ldif) kullanarak Netscape sunucularına/sunucularından göçü kolaylaştırır\&.Bu algoritma günümüz standartlarında \fBgüvenilmez\fR kabul edilmektedir\&.  
.TP
\fB-p\fR
Düz metin parolalar kullanılır\&. \fBhtpasswd\fR tarafından tüm platformlarda destekleniyor olsa da Windows, Netware ve TPF üzerinde httpd sunucusu tarafından sadece düz metin parolalar kabul edilir\&.  
.TP
\fB-D\fR
Kullanıcıyı siler\&. Kullanıcı belirtilen dosyada mevcutsa silinir\&.  
.TP
-v
Parolayı doğrular\&. Verilen parolayı belitilen htpasswd dosyasında saklanan kullanıcı parolası ile karşılaştırarak doğrulama yapar\&. 2\&.4\&.5 ve sonraki sürümler içindir\&.  
.TP
\fIparola-dosyası\fR
Kullanıcı ismini ve parolasını içeren dosyanın ismi\&. \fB-c\fR seçeneği verilmişse ve dosya mevcut değilse oluşturulur, dosya mevcutsa silinip yeniden oluşturulur\&.  
.TP
\fIkullanıcı\fR
\fIparola-dosyası\fR'nda oluşturulacak veya güncellenecek kullanıcı ismi\&. \fIkullanıcı\fR bu dosyada mevcut değilse yeni bir girdi eklenir\&. Girdi mevcutsa parolası değiştirilir\&.  
.TP
\fIparola\fR
Şifrelenip dosyada saklanacak düz metin parola\&. Sadece \fB-b\fR seçeneği ile kullanılır\&.  
 
.SH "ÇIKIŞ DURUMU"
 
.PP
\fBhtpasswd\fR, kullanıcı ismi ve parolasını DBM dosyasına başarıyla eklemiş veya güncellemişse 0, dosyalara erişirken bir sorun çıkmışsa 1, komut satırında bir sözdizimi hatası varsa 2, parola etkileşimli alınmış fakat girdi ile eşleşme sağlanamamışsa 3, işlem kesintiye uğramışsa 4, bir değer çok uzunsa 5 (kullanıcı, parola, dosya ismi veya açıklama), kullanıcı ismi kuraldışı karakter içeriyorsa (Kısıtlamalar bölümüne bakınız) 6 ve dosya geçerli bir DBM parola dosyası değilse 7 değeriyle döner\&.
 
.SH "ÖRNEKLER"
 
.nf

      htpasswd /usr/local/etc/apache/\&.htpasswd-users jsmith
    
.fi
 
.PP
jsmith kullanıcısı için parolayı ekler veya değiştirir\&. Parolayı vermesi için kullanıcıya parola isteği yapılır\&. Parola takviyeli Apache MD5 algoritması ile şifrelenir\&. Dosya mevcut değilse \fBhtpasswd\fR beklenen hiçbir işlemi yapmadan bir hata vererek çıkar\&.
 
.nf

      htpasswd -c /home/doe/public_html/\&.htpasswd jane
    
.fi
 
.PP
Yeni bir dosya oluşturur ve kullanıcı jane için kaydı bir girdi olarak bu dosyaya yazar\&. Dosya mevcutsa fakat okunamıyor veya yazılamıyorsa dosyada bir değişiklik yapılmaz ve \fBhtpasswd\fR bir ileti gösterip bir hata durumu ile çıkar\&.
 
.nf

      htpasswd -db /usr/web/\&.htpasswd-all jones Pwd4Steve
    
.fi
 
.PP
Komut satırından verilen parolayı (Pwd4Steve) crypt() algoritmasıyla şifreler ve bunu belirtilen dosyada saklar\&.
 
.SH "GÜVENLİK DEĞERLENDİRMELERİ"
 
.PP
\fBhtpasswd\fR tarafından yönetilen parola dosyalarına sunucunun URI uzayından erişilememelidir; yani dosya bir tarayıcı ile okunabilecek bir yerde bulunmamalıdır\&.
 
.PP
Bu program bir setuid çalıştırılabiliri olarak güvenilir olmadığından \fIsetuid yapılmamalıdır\fR\&.
 
.PP
Komut satırında parolanın şifrelenmemiş olarak görünmesi sebebiyle \fB-b\fR seçeneğinin kullanımından kaçınılmasını öneriyoruz\&.
 
.PP
crypt() algoritması kullanılırken, parolayı şekillendirmek için parolanın ilk 8 baytının kullanılacağına dikkat ediniz\&. Eğer parola 8 bayttan uzunsa kalanlar bir uyarı verilmeksizin iptal edilir\&.
 
.PP
SHA şifreleme biçeminde tuz kullanılmaz; yani, bir parolanın sadece bir şifreli gösterimi olabilir\&. crypt() ve MD5 biçemleri parolanın önüne rasgele üretilmiş bir tuz dizgesi eklediklerinden sözlük saldırılarına karşı daha dayanıklıdırlar\&.
 
.PP
SHA ve crypt() biçimleri günümüz standartlarında \fBgüvenilmez\fR kabul edilmektedir\&.
 
.SH "KISITLAMALAR"
 
.PP
Windows platformuda, \fBhtpasswd\fR ile şifrelenen parolalar 255 karakterden daha uzun olamaz\&. 255 karakterden sonrası kırpılır\&.
 
.PP
\fBhtpasswd\fR tarafından kullanılan MD5 algoritması Apache yazılımına özeldir; bu algoritma ile şifrelenen parolalar başka HTTP sunucularında kullanılamayabilir\&.
 
.PP
Kullanıcı isimleri 255 bayttan uzun olamaz ve iki nokta imi (:) içeremez\&.

.SH "ÖZET"
 
.PP
\fBhtcacheclean\fR, mod_cache_disk deposunun boyutlarını belli sınırlar içinde veya kullanımdaki dosya düğümlerinin sınırları içinde tutmak için kullanılır\&. Bu araç ya elle ya da bir artalan süreci olarak çalıştırılır\&. Artalan süreci olarak çalıştırıldığında, silinecek arabellek içeriğini tespit etmek için arabellek dizinlerine belli aralıklarla bakmak dışında uykuda olur\&. Artalan sürecini temiz olarak durdurmak için TERM veya INT sinyali göndermeniz yeterlidir\&. Elle çalıştırıldığında, silinecek arabellek içeriğini tespit etmek için arabellek dizinlerine bir kereliğine bakar\&. Bir veya daha fazla URL belirtilmesi durumunda arabellekte olanlar arabellekten silinir\&.
 

.SH "SEÇENEKLER"
 
 
.TP
\fB-d\fR\fI süre\fR
Artalanda çalışarak \fIsüre\fR dakikada bir arabelleği temizler\&. Bu seçenek \fB-D\fR, \fB-v\fR ve \fB-r\fR seçenekleri ile birlikte kullanılamaz\&. Artalan sürecini temiz olarak sonlandırmak için SIGTERM veya SIGINT göndermek yeterlidir\&.  
.TP
\fB-D\fR
Kuru kuruya çalışıp, hiçbir şeyi silmez\&. \fB-d\fR seçeneği ile birlikte kullanılamaz\&. Kuru çalıştırma sırasında \fB-t\fR seçeneği ile dizinler silinmek istenirse, statlarda silinmiş görünen dosya düğümleri silinmiş dizinler olarak hesaba katılmaz ve tahmini olarak imlenir\&.  
.TP
\fB-v\fR
Çıktı daha ayrıntılı olur\&. \fB-d\fR seçeneği ile birlikte kullanılamaz\&.  
.TP
\fB-r\fR
İyice temizlik yapılır\&. Bunun için Apache HTTP sunucusunun çalışmadığı varsayılır (aksi takdirde arabellek içeriği bozulabilir)\&. \fB-t\fR seçeneğinin de uygulanmasını sağlar\&. \fB-d\fR seçeneği ile birlikte kullanılamaz\&.  
.TP
\fB-n\fR

.TP
\fB-t\fR
Tüm boş dizinleri siler\&. Öntanımlı olarak, sadece arabellek dosyaları silinirse de bazı yapılandırmalarda büyük miktarda dizin oluşturulması bu seçeneğin kullanılmasını gerektirebilir\&. Yapılandırmanız çok sayıda dizin gerektiriyorsa ve dosya düğümlerinin veya dosya ayırma tablolarının tükenmesi sözkonusu ise bu seçeneğin kullanılması önerilir\&.  
.TP
\fB-p\fR\fI yol\fR
\fIyol\fR, disk arabelleğinin kök dizini olarak belirtilir\&. CacheRoot yönergesinde belirtilen dizin olmalıdır\&.  
.TP
\fB-P\fR\fIpiddosyası\fR
Artalan süreci olarak çalışmada süreç kimliğinin yazılacağı dosyanın adını belirtmek için kullanılır\&.  
.TP
\fB-R\fR\fIboyut\fR
Disk bloklarının boyunu denkleştirmek için yuvarlanacak üst boyutu belirtmekte kullanılır\&. Arabellek bölümünün blok boyutunu belirler\&.  
.TP
\fB-l\fR\fI sınır\fR
\fIsınır\fR, disk arabelleğinin toplam boyutu olarak belirtilir\&. Değerin öntanımlı olarak bayt cinsinden belirtileceği varsayılır\&. Değerin sonuna kilobayt için K, megabayt M, bayt için B harfi konulabilir\&.  
.TP
\fB-L\fR\fIlimit\fR
Disk arabellek dosyası düğümü toplamının sınırını belirlemekte kullanılır\&.  
.TP
\fB-i\fR

.TP
\fB-a\fR
O an arabellekte saklanmakta olan URL'leri listeler\&. Birden fazla aynı URL varsa yalnız biri listelenir\&.  
.TP
\fB-A\fR
O an arabellekte saklanmakta olan URL'leri öznitelikleri ile listeler\&. Öznitelikler şu sırayla verilir: url, header size, body size, status, entity version, date, expiry, request time, response time, body present, head request  
 
.SH "BELLİ BİR URL'NİN SİLİNMESİ"
 
.PP
\fBhtcacheclean\fR tarafından aktarılan URL'ler arabellekten silinir\&. Bir URL birden fazla mevcutsa hepsi silinir\&.
 
.PP
Ters vekilli bir URL silinmişse, etkin URL \fBHost\fR başlığı \fBport\fR, \fByol\fR ve \fBsorgu\fR ile oluşturulur\&. Bir sorgu dizgesi olsun olmasın, URL içinde '?' daima açıkça belirtilmelidir\&. Örneğin, \fBlocalhost\fR sunucusundaki \fB/\fR yolu silinmek istenirse silinecek URL \fBhttp://localhost:80/?\fR olurdu\&.
 
.SH "ARABELLEKTEKİ URL'LERİN LİSTELENMESİ"
 
.PP
\fBhtcacheclean\fR'e \fB-a\fR veya \fB-A\fR seçeneğinin aktarılmasıyla, arabellekteki URL'ler bulundukça her satıra bir URL gelecek biçemde listelenir\&. \fB-A\fR seçeneği URL'nin ardından arabellek içeriğini tamamını şu sırayla dökümler:
 
 
.TP
url
Öğenin URL'si\&. 
.TP
header size
Bayt cinsinden başlık uzunluğu\&. 
.TP

       for details.  YYERROR is fine as it does not invoke this
       function.
     - If this state is a consistent state with a default action, then
       the only way this function was invoked is if the default action
       is an error action.  In that case, don't check for expected
       tokens because there are none.
     - The only way there can be no lookahead present (in yychar) is if
       this state is a consistent state with a default action.  Thus,
       detecting the absence of a lookahead is sufficient to determine
       that there is no unexpected or expected token to report.  In that
       case, just report a simple "syntax error".
     - Don't assume there isn't a lookahead just because this state is a
       consistent state with a default action.  There might have been a
       previous inconsistent state, consistent state with a non-default
       action, or user semantic action that manipulated yychar.
     - Of course, the expected token list depends on states to have
       correct lookahead information, and it depends on the parser not
       to perform extra reductions after fetching a lookahead from the
       scanner and before detecting a syntax error.  Thus, state merging
       (from LALR or IELR) and default reductions corrupt the expected
       token list.  However, the list is correct for canonical LR with
       one exception: it will still contain any token that will not be
       accepted due to an error action in a later state.

 * Otherwise it's a name-vhost list, and the default is the server in the

 * conn_rec field vhost_lookup_data.  Later on after the headers we get a
 * second chance, and we use the name_chain to figure out what name-vhost
 * matches the headers.
 *
 * If there was no ip address match in the iphash_table then do a lookup

 * Signalling Apache on NT.
 *
 * Under Unix, Apache can be told to shutdown or restart by sending various
 * signals (HUP, USR, TERM). On NT we don't have easy access to signals, so
 * we use "events" instead. The parent apache process goes into a loop
 * where it waits forever for a set of events. Two of those events are
 * called
 *
 *    apPID_shutdown
 *    apPID_restart
 *
 * (where PID is the PID of the apache parent process). When one of these
 * is signalled, the Apache parent performs the appropriate action. The events
 * can become signalled through internal Apache methods (e.g. if the child
 * finds a fatal error and needs to kill its parent), via the service
 * control manager (the control thread will signal the shutdown event when
 * requested to stop the Apache service), from the -k Apache command line,
 * or from any external program which finds the Apache PID from the
 * httpd.pid file.
 *
 * The signal_parent() function, below, is used to signal one of these events.
 * It can be called by any child or parent process, since it does not
 * rely on global variables.
 *
 * On entry, type gives the event to signal. 0 means shutdown, 1 means
 * graceful restart.

 * master_main()
 * master_main() runs in the parent process.  It creates the child
 * process which handles HTTP requests then waits on one of three
 * events:
 *
 * restart_event
 * -------------
 * The restart event causes master_main to start a new child process and
 * tells the old child process to exit (by setting the child_exit_event).
 * The restart event is set as a result of one of the following:
 * 1. An apache -k restart command on the command line
 * 2. A command received from Windows service manager which gets
 *    translated into an ap_signal_parent(SIGNAL_PARENT_RESTART)
 *    call by code in service.c.
 * 3. The child process calling ap_signal_parent(SIGNAL_PARENT_RESTART)
 *    as a result of hitting MaxConnectionsPerChild.
 *
 * shutdown_event
 * --------------
 * The shutdown event causes master_main to tell the child process to
 * exit and that the server is shutting down. The shutdown event is
 * set as a result of one of the following:
 * 1. An apache -k shutdown command on the command line
 * 2. A command received from Windows service manager which gets
 *    translated into an ap_signal_parent(SIGNAL_PARENT_SHUTDOWN)
 *    call by code in service.c.
 *
 * child process handle
 * --------------------
 * The child process handle will be signaled if the child process
 * exits for any reason. In a normal running server, the signaling
 * of this event means that the child process has exited prematurely
 * due to a seg fault or other irrecoverable error. For server
 * robustness, master_main will restart the child process under this
 * condition.
 *
 * master_main uses the child_exit_event to signal the child process
 * to exit.

/**
 * This MPM tries to fix the 'keep alive problem' in HTTP.
 *
 * After a client completes the first request, the client can keep the
 * connection open to send more requests with the same socket.  This can save
 * significant overhead in creating TCP connections.  However, the major
 * disadvantage is that Apache traditionally keeps an entire child
 * process/thread waiting for data from the client.  To solve this problem,
 * this MPM has a dedicated thread for handling both the Listening sockets,
 * and all sockets that are in a Keep Alive status.
 *
 * The MPM assumes the underlying apr_pollset implementation is somewhat
 * threadsafe.  This currently is only compatible with KQueue and EPoll.  This
 * enables the MPM to avoid extra high level locking or having to wake up the
 * listener thread when a keep-alive socket needs to be sent to it.
 *
 * This MPM does not perform well on older platforms that do not have very good
 * threading, like Linux with a 2.4 kernel, but this does not matter, since we
 * require EPoll or KQueue.
 *
 * For FreeBSD, use 5.3.  It is possible to run this MPM on FreeBSD 5.2.1, if
 * you use libkse (see `man libmap.conf`).
 *
 * For NetBSD, use at least 2.0.
 *
 * For Linux, you should use a 2.6 kernel, and make sure your glibc has epoll
 * support compiled in.
 *

/* Multi-process, multi-threaded MPM for OS/2

 * Server consists of

 * - a small, static number of child processes
 *
 * The parent process's job is to manage the child processes. This involves
 * spawning children as required to ensure there are always ap_daemons_to_start
 * processes accepting connections.
 *
 * Each child process consists of a pool of worker threads and a
 * main thread that accepts connections & passes them to the workers via
 * a work queue. The worker thread pool is dynamic, managed by a maintenance
 * thread so that the number of idle threads is kept between
 * min_spare_threads & max_spare_threads.

 * Filters operate using a "chaining" mechanism. The filters are chained
 * together into a sequence. When output is generated, it is passed through
 * each of the filters on this chain, until it reaches the end (or "bottom")
 * and is placed onto the network.
 *
 * The top of the chain, the code generating the output, is typically called
 * a "content generator." The content generator's output is fed into the
 * filter chain using the standard Apache output mechanisms: ap_rputs(),
 * ap_rprintf(), ap_rwrite(), etc.
 *
 * Each filter is defined by a callback. This callback takes the output from
 * the previous filter (or the content generator if there is no previous
 * filter), operates on it, and passes the result to the next filter in the
 * chain. This pass-off is performed using the ap_fc_* functions, such as
 * ap_fc_puts(), ap_fc_printf(), ap_fc_write(), etc.
 *
 * When content generation is complete, the system will pass an "end of
 * stream" marker into the filter chain. The filters will use this to flush
 * out any internal state and to detect incomplete syntax (for example, an
 * unterminated SSI directive).

 * This function type is used for filter callbacks. It will be passed a

 * to be filtered.
 *
 * In filter->ctx, the callback will find its context. This context is
 * provided here, so that a filter may be installed multiple times, each
 * receiving its own per-install context pointer.
 *
 * Callbacks are associated with a filter definition, which is specified
 * by name. See ap_register_input_filter() and ap_register_output_filter()
 * for setting the association between a name for a filter and its
 * associated callback (and other information).
 *
 * If the initialization function argument passed to the registration
 * functions is non-NULL, it will be called iff the filter is in the input
 * or output filter chains and before any data is generated to allow the
 * filter to prepare for processing.
 *
 * The bucket brigade always belongs to the caller, but the filter
 * is free to use the buckets within it as it sees fit. Normally,
 * the brigade will be returned empty. Buckets *may not* be retained
 * between successive calls to the filter unless they have been
 * "set aside" with a call apr_bucket_setaside. Typically this will
 * be done with ap_save_brigade(). Buckets removed from the brigade
 * become the responsibility of the filter, which must arrange for
 * them to be deleted, either by doing so directly or by inserting
 * them in a brigade which will subsequently be destroyed.
 *
 * For the input and output filters, the return value of a filter should be
 * an APR status value.  For the init function, the return value should
 * be an HTTP error code or OK if it was successful.

/*
    The MPM, "multi-processing model" provides an abstraction of the
    interface with the OS for distributing incoming connections to
    threads/process for processing.  http_main invokes the MPM, and
    the MPM runs until a shutdown/restart has been indicated.
    The MPM calls out to the apache core via the ap_process_connection
    function when a connection arrives.

    The MPM may or may not be multithreaded.  In the event that it is
    multithreaded, at any instant it guarantees a 1:1 mapping of threads
    ap_process_connection invocations.

    Note: In the future it will be possible for ap_process_connection
    to return to the MPM prior to finishing the entire connection; and
    the MPM will proceed with asynchronous handling for the connection;
    in the future the MPM may call ap_process_connection again -- but
    does not guarantee it will occur on the same thread as the first call.

    The MPM further guarantees that no asynchronous behaviour such as
    longjmps and signals will interfere with the user code that is
    invoked through ap_process_connection.  The MPM may reserve some
    signals for its use (i.e. SIGUSR1), but guarantees that these signals
    are ignored when executing outside the MPM code itself.  (This
    allows broken user code that does not handle EINTR to function
    properly.)

    The suggested server restart and stop behaviour will be "graceful".
    However the MPM may choose to terminate processes when the user
    requests a non-graceful restart/stop.  When this occurs, the MPM kills
    all threads with extreme prejudice, and destroys the pchild pool.
    User cleanups registered in the pchild apr_pool_t will be invoked at
    this point.  (This can pose some complications, the user cleanups
    are asynchronous behaviour not unlike longjmp/signal... but if the
    admin is asking for a non-graceful shutdown, how much effort should
    we put into doing it in a nice way?)

    unix/posix notes:
    - The MPM does not set a SIGALRM handler, user code may use SIGALRM.
        But the preferred method of handling timeouts is to use the
        timeouts provided by the BUFF abstraction.
    - The proper setting for SIGPIPE is SIG_IGN, if user code changes it
        for any of their own processing, it must be restored to SIG_IGN
        prior to executing or returning to any apache code.
    TODO: add SIGPIPE debugging check somewhere to make sure it's SIG_IGN

/*
 * request.c is the code which handles the main line of request
 * processing, once a request has been read in (finding the right per-
 * directory configuration, building it if necessary, and calling all
 * the module dispatch functions in the right order).
 *
 * The pieces here which are public to the modules, allow them to learn
 * how the server would handle some other file or URI, or perhaps even
 * direct the server to serve that other file instead of the one the
 * client requested directly.
 *
 * There are two ways to do that.  The first is the sub_request mechanism,
 * which handles looking up files and URIs as adjuncts to some other
 * request (e.g., directory entries for multiviews and directory listings);
 * the lookup functions stop short of actually running the request, but
 * (e.g., for includes), a module may call for the request to be run
 * by calling run_sub_req.  The space allocated to create sub_reqs can be
 * reclaimed by calling destroy_sub_req --- be sure to copy anything you care
 * about which was allocated in its apr_pool_t elsewhere before doing this.

/*
    test-writev: use this to figure out if your writev() does intelligent
    things on the network.  Some writev()s when given multiple buffers
    will break them up into multiple packets, which is a waste.

    Linux prior to 2.0.31 has this problem.

    Solaris 2.5, 2.5.1 doesn't appear to, 2.6 hasn't been tested.

    IRIX 5.3 doesn't have this problem.

    To use this you want to snoop the wire with tcpdump, and then run
    "test-writev a.b.c.d port#" ... against some TCP service on another
    box.  For example you can run it against port 80 on another server.
    You want to look to see how many data packets are sent, you're hoping
    only one of size 300 is sent.

SNI Files generated
===================

The directory ${DIR}/sni has been populated with the following

-       root.key|pem    Certificate authority root and key. (You could
                        import the root.pem key into your browser to
                        quell warnings about an unknown authority).

-       hosts           /etc/hosts file with fake entries for the hosts

-       htdocs          directory with one docroot for each domain,
                        each with a small sample file.

-       ssl             directory with an ssl cert (signed by root)
                        for each of the domains).

-       logs            logfiles, one for each domain and an
                        access_log for any misses.

The directory ${CDIR} contains optional test files to allow client
authentication testing:

-       client*pem/p12  Files for client authentication testing. These
                        need to be imported into the browser.

-       xs-root-1/2     Certificate authority which has issued above
                        client authentication certificates.

-       xs-root-dir     A directory specific for the SSLCACertificateDir
                        directive.

-       xs-root-chain   A chain of the two client xs authorities for the
                        SSLCACertificate directive.

SNI Test
========

A directory ${DIR}/sni has been created. Run an apache
server against it with

    .../httpd -f ${DIR}/httpd-sni.conf

and keep an eye on ${DIR}/logs/error_log. When everything 
is fine you will see entries like:

    Feb 11 16:12:26 2008] [debug] Init: 
        SSL server IP/port overlap: ape.*:443 (httpd-sni.conf:24) vs. jane.*:443 (httpd-sni.conf:42)

for each vhost configured and a concluding warning:

    [Mon Feb 11 16:12:26 2008] [warn] Init: 
        Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366)

HOWEVER - If you see an entry like:

    [Mon Feb 11 15:41:41 2008] [warn] Init: 
        You should not use name-based virtual hosts in conjunction with SSL!!

then you are either using an OpenSSL which is too old and/or you need to ensure that the
TLS Extensions are compiled into openssl with the 'enable-tlsext' flag. Once you have
recompiled or reinstalled OpenSSL with TLS Extensions you will have to recompile mod_ssl
to allow it to recognize SNI support.

Meanwhile add 'hosts' to your c:\windows\system32\drivers\etc\hosts
or /etc/hosts file as to point the various URL's to your server:
$LST

and verify that each returns its own name (and an entry in its
own ${DIR}/logs) file).

NOTE
====

Note that in the generated example the 'first' domain is special - and is the
catch all for non-SNI browsers. Depending on your circumstances it may make
sense to use a generic name - and have each of the SNI domains as subdirectories
(and hence URI's under this generic name). Thus allowing non SNI browsers also
access to those sites.

Variables
---------

The Travis scripts use the following environment variables:

* APR_VERSION - if set, APR of this version is built and installed in
  $HOME/root/apr-$APR_VERSION - a value of "trunk" means trunk is
  used, "*.x" means a branch, otherwise a tagged version is implied.

* APR_CONFIG - arguments to pass when running APR's configure script
  if APR_VERSION is set

* APU_VERSION - if set, APR-util of this version is built and
  installed in $HOME/root/apr-util-$APU_VERSION - a value of "*.x"
  means a branch, otherwise a tagged version is implied.  (Since there
  is no "trunk" for apr-util, that value cannot be used here.)

* APU_CONFIG - arguments to pass when running APR-util's configure
  script if APU_VERSION is set

* CONFIG - arguments to pass to httpd's configure script.

* BUILDCONFIG - arguments to pass when running httpd's ./buildconf script

* MFLAGS - arguments to pass when running "make" for httpd.

* SKIP_TESTING - if set, the Perl test framework is not run for the
  build.

* TEST_UBSAN - set for job using UBSan ("Undefined Behaviour Sanitizer")

* TEST_MALLOC - set for job using enhanced malloc debugging.

* TEST_INSTALL - set for job testing "make install"

* TEST_VPATH - set for job testing srcdir!=builddir 

* TEST_LDAP - set for job with slapd, running LDAP tests

* TEST_SSL - set for job with SSL/TLS testing variants

* TESTS - a list of Perl framework tests to run

* TEST_ARGS - arguments to pass to ./t/TEST in the Perl test framework

Caching
-------

Perl modules installed in $HOME/perl5 are cached.

Anything installed into the $HOME/root directory is cached - notably,
versions of APR/APR-util are installed here and cached across httpd
build jobs without needing to be rebuilt every time.

TODO list
---------

* MacOS build
* Windows build
* clang-on-Linux build
* Use containers for non-Ubuntu-based Linux testing
* sanity checks for use of APLOGNO() - empty arguments, accidental duplicates, etc.
 - not sure how exactly
* Known test failures
 - "apt-get install" timeout/fails - workaround by moving apt install to before_script phase?

Testing from a Feature Branch
-----------------------------

An SVN branch off trunk should be mirrored to github, and will be
tested in the same way that trunk is in Travis, so this workflow is
available for those familiar with using Subversion and the standard
ASF/httpd repository layout.

Tested branches are listed at: https://travis-ci.org/github/apache/httpd/branches

Travis will also run the tests for a PR filed against the httpd Github
repository at https://github.com/apache/httpd or from a fork of this
repository if enabled for the Travis user.

A workflow to enable testing would be as follows, substituting
$USERNAME for your github username:

  $ git clone https://github.com/apache/httpd
  $ cd httpd
  $ git remote add $USERNAME git@github.com:$USERNAME/httpd.git
  $ git checkout -b my-feature origin/trunk
  ... do some work ...
  $ git commit ...
  $ git push -u $USERNAME my-feature:my-feature

To enable testing for a fork, visit the settings page at
https://travis-ci.org/$USERNAME/httpd/settings - you may need to sync
your account via https://travis-ci.org/account/repositories for a
freshly created fork.

To create a Pull Request, go to a URL like:
https://github.com/apache/httpd/compare/trunk...$USERNAME:trunk

Once a PR has been created, travis will run the tests and link the
results from a PR comment. All tested PRs are listed here:
https://travis-ci.org/github/apache/httpd/pull_requests

To merge from github back to SVN trunk, create a patch from e.g.:

  $ git diff origin/trunk..my-feature

and then apply it in SVN.  To rebase a feature once trunk has
diverged, from a feature branch run:

  $ git pull
  $ git rebase -i origin/trunk

and follow the standard rebase steps.

=========================
Using pytest (<https://docs.pytest.org/en/6.2.x/>) and a Python >= 3.8
for a more flexible testing of Apache httpd.

Usage
-----
In your httpd source checkout, do:

> make install
> pytest

and all tests defined run on the installed executable and modules.
> pytest test/modules/core
runs all the core tests. You can run tests also by name selection:
> pytest -k test_core
runs all test cases starting with 'test_core'. Similar:
> pytest -k test_core_001_04
runs the test cases starting with that.

Test output gets more verbose, by adding one or several '-v'. This
also raises the error log level of the tested modules.
> pytest -vvv -k test_h2_004_01
run the specific test with mod_http2 at log level TRACE2.

By default, test cases will configure httpd with mpm_event. You
can change that with the invocation:
> MPM=worker pytest test/modules/http2

Some tests rely on additional tools installed in your environment
and will 'skip' if those are not present. In a non-verbose run,
these will appear as 's' in the output. If you run pytest more
verbose, the skipped test cases will mention a reason for why
they are disabled.

For example, most tests in test/modules/md require an installation
of 'pebble', an ACME test server, and look for it in $PATH.


Workings
--------
All tests start httpd on their own and try hard to shut it down
afterwards. You can abort tests with ^C and they clean up.

httpd is started/stopped repeatedly in testing as configurations
for individual test cases are changed. This is a main difference to
the Perl test framework which starts the server with all possible
combinations configured that are needed by tests.

In test/gen/apache a server root is created with config, logs and htdocs
directories. test/gen/apache/logs/error_log will be the log.
Configs start in test/gen/apache/conf/httpd.conf. modules.conf is
dynamically created for the list of modules that a test suite needs.

Test cases write their specific setup in test.conf and reload/restart
the httpd process. This makes for a small configuration in a test case.


Development
-----------

Adding a test in an existing file is done by adding a method. Its name
must start with 'test_' and the common practise is to have the name
of the test suite there as well. All http2 tests start with 'test_h2_'.

Following this can be any characters. If you make test cases of a
certain feature with a common prefix, it is easier to invoke just
them using the '-k' selector on the command line.

You can also add just a new file to a test suite, if you do a new
range of test cases that do not fit anywhere else. A very simple
one is found in test/modules/http2/test_001_httpd_alive.py.

There is a python class defined with 2 methods. One is the test
method itself and the other one ' is

    @pytest.fixture(autouse=True, scope='class')
    def _class_scope(self, env):
        code

is marked as a pytest 'fixture'. This is some pytest magic.
'autouse=True' means that this fixture is run, even though
no test case uses it directly. scope='class' means that it
is run once for all test cases in this class.

As you see, this fixture gets a parameter named 'env' and
that is the name of another pytest fixture, defined in the
file 'conftest.py' in the same directory.

    @pytest.fixture(scope="package")
    def env(pytestconfig) -> H2TestEnv:
        code

This one runs one time per 'package', meaning for all test
cases in this directory. And it gets the 'pytestconfig'
as parameter which is a standard pytest fixture.

So, when you run 'pytest -k test_h2_004', pytest will look
at _all_ test cases defined and collect those with that
prefix. For each directory with test cases found, it will
process the 'conftest.py', boot-strapping the 'env' fixture,
and the process the files with active test cases.

As a result, if you invoke just a single test case, only
the fixtures needed for that test case are created. This
gives good turn around times when debugging a test case.

If you want to add a new test suite, create a new directory.
Add the files '__init__.py', 'conftest.py' and a first
'test_suitename_something.py'. test/modules/core is the
simplest example. 'test/modules/http2' shows how you load
other modules. 'test/modules/md' checks and starts external
processes (an ACME test server).


Infrastructure
--------------
The test cases rely on the classes provided in 'test/pyhttpd'
for common code in managing a httpd test instance and do
provide some base setups:
- a small set of virtual hosts with some files
- access to paths and definitions (env fixture)
- start/stop httpd and inspect the error log
- run clients like curl and nghttp
- create certificates for your hosts and make curl use
  the root certs (so no --insecure calls by curl).

/*
time-sem.c has the basics of the semaphores we use in http_main.c.  It's
intended for timing differences between various methods on an
architecture.  In practice we've found many things affect which semaphore
to be used:

    - NFS filesystems absolutely suck for fcntl() and flock()

    - uslock absolutely sucks on single-processor IRIX boxes, but
        absolutely rocks on multi-processor boxes.  The converse
        is true for fcntl.  sysvsem seems a moderate balance.

    - Under Solaris you can't have too many processes use SEM_UNDO, there
        might be a tuneable somewhere that increases the limit from 29.
        We're not sure what the tunable is, so there's a define
        NO_SEM_UNDO which can be used to simulate us trapping/blocking
        signals to be able to properly release the semaphore on a clean
        child death.  You'll also need to define NEED_UNION_SEMUN
        under solaris.

You'll need to define USE_SHMGET_SCOREBOARD if anonymous shared mmap()
doesn't work on your system (i.e. linux).

argv[1] is the #children, argv[2] is the #iterations per child

You should run each over many different #children inputs, and choose
#iter such that the program runs for at least a second or so... or even
longer depending on your patience.

compile with:

gcc -o time-FCNTL -Wall -O time-sem.c -DUSE_FCNTL_SERIALIZED_ACCEPT
gcc -o time-FLOCK -Wall -O time-sem.c -DUSE_FLOCK_SERIALIZED_ACCEPT
gcc -o time-SYSVSEM -Wall -O time-sem.c -DUSE_SYSVSEM_SERIALIZED_ACCEPT
gcc -o time-SYSVSEM2 -Wall -O time-sem.c -DUSE_SYSVSEM_SERIALIZED_ACCEPT -DNO_SEM_UNDO
gcc -o time-PTHREAD -Wall -O time-sem.c -DUSE_PTHREAD_SERIALIZED_ACCEPT -lpthread
gcc -o time-USLOCK -Wall -O time-sem.c -DUSE_USLOCK_SERIALIZED_ACCEPT

not all versions work on all systems.

Reply-To: new-httpd@apache.org

Anyone too lazy to hack tcpdump (eg. my tcpdump has a -X option to display
the data in ASCII) can use something like the below to grab HTTP headers
when debugging broken clients.

Nothing complicated, but handy.

I usually just use this perl script, which I call "tcpdumpscii".
Then run "tcpdumpscii -s 1500 -x [other tcpdump args]".

# Although created for httpd, this file is used by many software systems
# and has been placed in the public domain for unlimited redisribution.
#
# The table below contains both registered and (common) unregistered types.
# A type that has no unique extension can be ignored -- they are listed
# here to guide configurations toward known types and to make it easier to
# identify "new" types.  File extensions are also commonly used to indicate
# content languages and encodings, so choose them carefully.
#
# Internet media types should be registered as described in RFC 4288.
# The registry is at <http://www.iana.org/assignments/media-types/>.
